RESUMEN
BACKGROUND: Carbonyl stress, a metabolic state characterized by elevated production of reactive carbonyl compounds (RCCs), is closely related to oxidative stress and has been implicated in various diseases. This study aims to investigate carbonyl stress parameters in drug-free bipolar disorder (BD) patients compared to healthy controls, explore their relationship with clinical features, and assess the effect of treatment on these parameters. METHODS: Patients with a primary diagnosis of a manic episode of BD and healthy controls were recruited. Exclusion criteria included intellectual disability, presence of neurological diseases, chronic medical conditions such as diabetes mellitus and metabolic syndrome, and clinical signs of inflammation. Levels of serum carbonyl stress parameters were determined using high-performance liquid chromatography. RESULTS: Levels of glyoxal (GO) and methylglyoxal (MGO) did not differ between pre- and post-treatment patients, but malondialdehyde (MDA) levels decreased significantly post-treatment. Pre-treatment MGO and MDA levels were higher in patients compared to controls, and these differences persisted post-treatment. After adjusting for BMI and waist circumference, only MDA levels remained significantly higher in patients compared to controls. LIMITATIONS: The study's limitations include the exclusion of female patients, which precluded any assessment of potential gender differences, and the lack of analysis of the effect of specific mood stabilizers or antipsychotic drugs. CONCLUSIONS: This study is the first to focus on carbonyl stress markers in BD, specifically GO, MGO, and MDA. MDA levels remained significantly higher in patients, suggesting a potential role in BD pathophysiology. MGO levels were influenced by metabolic parameters, indicating a potential link to neurotoxicity in BD. Further research with larger cohorts is needed to better understand the role of RCCs in BD and their potential as therapeutic targets.

INTRODUCTION: The ghrelin system, which generates the appetite hormone, is harmed by obesity, a problem of worldwide public health. An efficient way to cure obesity is through bariatric surgery. This randomized controlled study's objective was to assess preoperative diet-related DNA methylation of Ghrelin (GHRL) levels in patients undergoing bariatric surgery. METHODS: The 50 patients who volunteered to participate in the trial were randomly divided into two groups. The study group followed the very low-calorie diet for 2 weeks. The control group did not follow any diet. The physiological parameters, weight, and DNA methylation levels of the patients were assessed. RESULTS: The percentage of excess weight loss (EWL) in the control and study groups was determined as 47.1% and 51.5%, respectively. The study group's GHRL percentage of methylated reference was 76.8%, whereas the control group's was 67.3%. It was concluded that the EWL and GHRL gene DNA methylation of the diet-treated study group were significantly higher than the control group (p < 0.05). CONCLUSION: According to the findings, the pre-op diet had a favorable effect on the patient's behavior modification. It has also been shown to increase postoperative weight loss and DNA methylation of the Ghrelin gene. The ghrelin gene has been muted by methylation, making hunger regulation more manageable.

When the studies are evaluated, immunomodulatory effect of MSCs, administration in critically ill patients, obstacle situations in use and side effects, pulmonary fibrosis prevention, which stem cells and their products, regeneration effect, administration route, and dosage are listed under the main heading like. The effect of MSC administration on DNA repair genes in COVID-19 infection is unknown. Our aim is to determine the effect of mesenchymal stem cells (MSCs) therapy applied in critically ill patients with coronavirus infection on DNA repair pathways and genes associated with those pathways. Patients (n = 30) divided into two equal groups. Group-1: Patients in a critically ill condition, Group-2: Patients in critically ill condition and transplanted MSCs. The mechanism was investigated in eleven genes of five different pathways; Base excision repair: PARP1, Nucleotide excision repair (NER): RAD23B and ERCC1, Homologous recombinational repair (HR): ATM, RAD51, RAD52 and WRN, Mismatch repair (MMR): MLH1, MSH2, and MSH6, Direct reversal repair pathway: MGMT. It was found that MSCs application had a significant effect on 6 genes located in 3 different DNA damage response pathways. These are NER pathway genes; RAD23 and ERCC1, HR pathway genes; ATM and RAD51, MMR pathway genes; MSH2 and MSH6 (p < 0.05). Two main points were shown. First, as a result of cellular damage in critical patients with COVID-19, DNA damage occurs and then DNA repair pathways and genes are activated in reaction to this situation. Second, administration of MSC to patients with COVID-19 infection plays a positive role by increasing the expression of DNA repair genes located in DNA damage pathways.
RESUMEN
Background: Two fundamental challenges in the current therapeutic approach for central nervous system tumors are the tumor heterogeneity and the absence of specific treatments and biomarkers that selectively target the tumor tissue. Therefore, we aimed to investigate the potential relationship between discoidin domain receptor 1 (DDR1) expression and the prognosis and characteristics of glioma patients. Materials and Methods: Tissue and serum samples from 34 brain tumor patients were evaluated for DDR1 messenger ribonucleic acid levels in comparison to 10 samples from the control group, and Kaplan-Meier survival analysis has performed. Results: DDR1 expression was observed in both tissue and serum samples of the patient and control groups. DDR1 expression levels in tissue and serum samples from patients were higher in comparison to the control group, although not statistically significant (P > 0.05). A significant correlation between tumor size and DDR1 serum measurements at the level of 0.370 was reported (r = 0.370; P = 0.034). The levels of DDR1 in serum showed a positive correlation with the increasing size of tumor. The results of the 5-year survival analysis depending on the DDR1 tissue levels showed a significantly higher survival rate (P = 0.041) for patients who have DDR1 tissue levels above cutoff value. Conclusions: DDR1 expression was significantly higher among brain tumor tissues and serum samples and its levels showed a positive correlation with the increased size of tumor. This study can be a starting point, since it investigated and indicated, for the first time, that DDR1 can be a novel therapeutic and prognostic target for aggressive high-grade gliomas.

This study evaluated the short and long-term prognostic value of galectin-3 in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). Patients (n = 143) were admitted with STEMI and followed up for 2 years. The study population was divided into high and low galectin-3 groups based on the admission median value of serum galectin-3. Primary clinical outcomes consisted of cardiovascular (CV) mortality, non-fatal reinfarction, stroke, and target vessel revascularization (TVR). CV events were recorded in hospital and at 1 and 2 years. The primary clinical outcomes (in-hospital, 1 year and 2 year) were significantly higher in the high galectin-3 group. (P = .008, P = .004, P = .002, respectively). High galectin-3 levels were also associated with heart failure development and re-hospitalization at both 1 year (P = .029, P = .009, respectively) and 2 years (P = .019, P = .036, respectively). According to Cox multivariate analysis, left ventricular ejection fraction (LVEF) was an independent predictor of 2-year cardiovascular mortality (P = .009), whereas galectin-3 was not (P = .291). Although high galectin-3 levels were not independent predictors of long-term CV mortality in patients with acute STEMI who underwent primary PCI, it was associated with short-term and long-term development of adverse CV events, heart failure, and re-hospitalization.

Mammography is one of the gold standard screening tests for breast cancer. The effects of mammography procedure on blood parameters are not known. This study aimed to investigate whether the procedure-associated breast compression affects the widely and simultaneously performed blood measurements of C-reactive protein (CRP), carcinoembryonic antigen (CEA), and cancer antigen (CA) 15-3. According to breast ultrasound examination results, participants were divided into 3 groups as follows: group 1 (participants with breast mass size ≥20.0 mm, n=48); group 2 (participants with breast mass size <20.0 mm, n=17); and group 3 (participants with no breast mass, n=23). In groups 1 and 2, on the day of the mammographic imaging study, serum CRP, CEA, and CA 15-3 levels were measured before and after the imaging study. Participants in group 3 had their blood parameters measured without mammography and/or any breast compression. Post-mammography blood measurements displayed a significant increase in serum CRP levels, and a significant decrease in serum CEA and CA 15-3 levels in group 1 (in comparison with the same day pre-mammography blood sampling levels; p<0.05 all). Although pre-mammography serum CEA levels in group 1 participants were significantly higher than those in group 2 and 3 participants, this significant elevation became nonsignificant at post-mammography measurements (p<0.05 and p>0.05, respectively). On the day of the mammographic imaging study, the optimal time of blood sampling for testing CRP, CEA and CA 15-3 levels in persons with a breast mass is before, but not after the mammographic imaging procedure. This issue requires additional detailed studies.

Background and Aims: We aimed to assess N-terminal pro brain-type natriuretic peptide (NT-proBNP) levels in acute ischemic stroke (AIS) patients according to clinical and radiological features and to investigate its relationship with short term clinical outcomes. Methods: In our study, 107 patients with AIS were evaluated prospectively. Of all, 56 patients had no evidence of atrial fibrillation (AF) (sinus rhythm [SR] group) (52.3%), 24 patients had paroxysmal AF (pAF group) (22.4%), and the other 27 patients had chronic AF (cAF group) (25.3%). Demographic datas, clinical characteristics, laboratory and radiological findings, CHA2DS2 -VASc scores, NIHSS (National Institute of Health Stroke Scale) and modified Rankin Scale (mRS) scores on admission and at the third month evaluations were recorded. Good functional outcome at 3 months was defined as modified Rankin score (mRS) 2 or less. According to the TOAST (Trial of Org 10172 in Acute StrokeTreatment) and OCSP (Oxfordshire Community Stroke Project) study, ischemic stroke subtyping was performed. Serum NT-proBNP levels were estimated in 107 stroke patients and 24 age- and sex-matched control subjects. Venous blood samples were obtained for serum NT-proBNP measurement within the first 48 hours of the patient group. Results: Mean age of the 107 AIS patients was 68 ± 15.22 years and 58.9% of them were women. Compared to controls, the SR, pAF and cAF groups had higher plasma NT-proBNP levels (P < 0.001) and also NT-proBNP values were significantly higher in the pAF and cAF group than SR groups (P < 0.001). NT-proBNP values were significantly higher in cardioembolic (CE) (n = 57) group than in large artery atherosclerosis (LAA) (n = 20) and small vessel disease (SVD) (n = 30) groups (P < 0.001). NT-proBNP levels of noncardioembolic SR (n = 49) (P = 0.080), LAA and SVD groups (P = 0.103) were higher than the control group but the difference was not statistically significant. There was a positive correlation between NT-proBNP level and third month mRS scores in CE group (r = 0.491). Conclusions: NT-proBNP will contribute to predict cardioembolic and pAF groups and estimate the prognosis.

The epigenetic features contribute to variations in host susceptibility to SARS-CoV-2 infection and severity of symptoms. This study aimed to evaluate the relationship between the relative expression of microRNAs (miRNAs) and the severity of the disease in COVID-19 patients. The miRNA profiles were monitored during the different stages of the disease course using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The expression levels of the selected 11 miRNAs were measured in the blood samples collected from 73 patients (moderate, n = 37; severe, n = 25; critically ill, n = 11, a total of 219 longitudinal samples) on hospitalization day and days 7 and 21. Expression changes were expressed as "fold change" compared to healthy controls (n = 10). Our study found that several miRNAs differed according to disease severity, with the miR-155-5p the most strongly upregulated (p = 0.0001). A statistically significant negative correlation was observed between the expression of miR-155-5p and its target gene, the suppressor of cytokine signaling 1 (SOCS1). The relative expression of miR-155-5p was significantly increased and SOCS1 was significantly decreased with the disease progression (r = -0.805 p = 0.0001, r = -0.940 p = 0.0001, r = -0.933 p = 0.0001 for admission, day 7, and day 21, respectively). The overexpression of miR-155-5p has significantly increased inflammatory cytokine production and promoted COVID-19 progression. We speculated that microRNA-155 facilitates immune inflammation via targeting SOCS1, thus establishing its association with disease prognosis.

INTRODUCTION: The aim of this study was to evaluate the physical structure, design, management, and organization of two emergency hospitals built in Istanbul within 45 days in the COVID-19 pandemic and the role played by these hospitals during the pandemic. A further aim was to determine the advantages and disadvantages of the emergency hospitals by comparing them with similar organizational models in other countries. METHODS: The pandemic hospitals established for the COVID-19 pandemic in Istanbul were investigated in a multi-faceted manner. The parameters investigated were physical structure, bed, and intensive care capacity, mechanics and infrastructure, medical equipment, personnel, organizational structures and management, and the medical services provided by both emergency hospitals during the outbreak. RESULTS: The pandemic hospitals were built on an open area of 125.000 m2 as a hospital building of 75.150 m2. Each hospital has a total bed capacity of 1008, with 576 being clinical and 432 being intensive care beds. The management of the pandemic hospitals is connected to two different hospital management structures, which are experienced in disasters and have all kinds of training, research clinics and academic personnel in this regard. CONCLUSION: The healthcare services provided by both the pandemic hospitals fulfilled the purpose of those hospitals during the pandemic. As it is most likely that the world will face other serious disasters and epidemics in the future, the construction of multi-purpose and permanent emergency hospitals instead of emergency temporary hospitals would be more advantageous in terms of economy, medical service, and environment.
RESUMEN
The diagnostic role of serum cytokines depends on the etiology and pathogenesis of acute appendicitis but the clinical significance of these cytokines in the differential diagnosis of complicated acute appendicitis remains unclear. To investigate the prediction of progression and diagnostic values of interleukin-6, interleukin-1 beta, and tumor necrosis factor-alpha in complicated acute appendicitis. This study was conducted in 100 patients with a definitive diagnosis of acute appendicitis and 20 individuals assigned for the control group. Venous blood was collected to assess biochemical tests, as well as interleukin-6, interleukin-1ß, and tumor necrosis factor-α levels. Serum levels of all parameters were dramatically higher in the complicated group compared with uncomplicated. Duration of hospitalization, rates of postoperative infection, intraabdominal abscess, and re-hospitalization were higher in complicated group. Cut-off points of WBC, CRP, NLR, interleukin-6, interleukin-1ß and tumor necrosis factor-α were 13.5x103/µL, 1.92 mg/dL, 6.09, 23.4 pg/mL, 5.6 pg/mL and 24 pg/mL (p=0.0014, p<0.001, p=0.009, respectively and p<0.001 for the rest). AUC of interleukin-6 was larger than AUCs of all other parameters, suggesting the highest predicting power of interleukin-6 among other parameters. Serum interleukin-6, interleukin-1ß, and tumor necrosis factor-α levels are valuable diagnostic parameters to predict a complicated acute appendicitis.

Introduction: Early diagnosis reduces mortality and morbidity rates in gastrointestinal system (GIS) anastomoses. Aim: The aim of the present study was to investigate the importance of some substances that were used to detect major complications early in patients who were treated in line with the Enhanced Recovery After Surgery (ERAS) protocol for gastric cancer. Factors included in the study were interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), procalcitonin (PCT) and white blood cell (WBC). Material and methods: A hundred and twenty patients who underwent laparoscopic subtotal or total gastrectomy for gastric cancer in accordance with the ERAS protocol between January 2018 and December 2019 were included in this prospective study. Blood values of IL-1ß, TNF-α, CRP, PCT, and WBC on the third and fifth post-operative days (POD) were measured for diagnosing major complications. Results: Major complications occurred in 12 (10%) patients. Third POD and fifth POD measurements of IL-1ß, TNF-α, CRP, PCT were statistically significantly higher than those in the non-complicated group, whereas WBC was not. In addition, in the group with complications, statistically significant changes of the blood levels of IL-1ß, TNF-α, CRP, and PCT between the 3rd and 5th days were detected (p = 0.008, p = 0.001, p = 0.004, p = 0.001 respectively). Conclusions: IL-1ß, TNF-α, CRP, and PCT can be used in the early detection of major complications in gastric cancer patients undergoing the ERAS protocol. Imaging methods should be used in patients with high levels of these inflammatory substances on the third and fifth POD.
RESUMEN
Pentraxin 3 (PTX3), a long pentraxin, is not only released from dendritic cells and neutrophils but also from epithelial and endothelial cells such as alveolar epithelium. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) initially activates the innate immune system, causing a complex immune response. Clinical and experimental studies suggest that PTX3, a locally and systemically secreted marker, can be used as a predictor of the severity and mortality in respiratory infections. In the current study, serum PTX3 levels in patients hospitalized with COVID-19 were found to be significantly increased at admission and showed significant association with the disease severity.

BACKGROUND: To determine and compare nasopharyngeal microbiota (NM) composition, in vitro basal (Nil tube), provoked (Mitogen tube) production of cytokines at the early stage of COVID-19. METHODS: This cross-sectional study included 4 age and sex-matched study groups; group 1 (recovered COVID-19) (n = 26), group 2 (mild COVID-19) (n = 24), group 3 (severe COVID-19) (n = 25), and group 4 (healthy controls) (n = 25). The study parameters obtained from the COVID-19 (group 2, and 3) at the early phase of hospital admission. RESULTS: The results from the reaserch deoicted that the Mean ± SD age was 53.09 ± 14.51 years. Some of the in vitro cytokines production was significantly different between the study groups. Some of the findinggs on cytokines depicted a significant differences between study groups were interleukin (IL)-1ß Nil, IL-1ß Mitogen, and their subtraction (i.e Mitogen-Nil). Regarding IL-10, and IL-17a levels, Mitogen, and Mitogen-Nil tube production levels were significantly different between the groups. Surprisingly, most of these measures were lowest in the severe COVID-19 patients' group. Using discriminant analysis effect size (LEfSe), Taxa of NM with significant abundance was determined. About 20 taxa with an LDA score > 4 were identified as candidate biomarkers. Some of these taxa showed a significant correlation with IL-1ß and IL-10 Mitogen and Mitogen- Nil levels (R > 0.3 or < -0.3, p < 0.05). CONCLUSIONS: The findings of this perticular study regarting the early stage of COVID-19 showed that in vitro cytokines production, studies might be more useful than the ordinary cytokines' blood level measurement. Besides, the study identified some NM species that could be candidate biomarkers in managing this infection. However, further detailed studies are needed in these fields.

The main culprit behind most cancers is the accumulation of reactive oxygen species. Glyoxal (GO) and methylglyoxal (MGO) are reactive intermediates created by food processing and they are precursors of advanced glycation end products (AGE) that cause glycative stress. We aimed to evaluate the relationship between AGE levels of healthy volunteers and treatment-naive patients diagnosed with colorectal cancer. The study consisted of patients diagnosed with colorectal cancer and healthy volunteers who underwent routine colonoscopy. The study was conducted with a total of 42 cases, 47.6% (n = 20) female. The ages of the participants in the study ranged from 41 to 82 years, and the mean was 60.57 ± 10.78 years. The GO and MGO values of the patient group were found to be significantly higher than those of the control group (p = 0.007, p = 0.001, respectively). The risk of colorectal cancer was 22 and 57 times higher in individuals with GO and MGO values above 1.25 µg/mL and 0.0095 µg/mL, respectively. The blood AGE level is closely related to diet, and it can be decreased through the appropriate improvement of diet. Thus, the measurement of AGE can be used to predict whether a person's nutrition is healthy or unhealthy and prevent increased risk of colorectal cancer.

OBJECTIVE: The prevalence of diabetes mellitus is growing worldwide, as well as in the aging population, and its comorbidity and mortality rates are higher in aging people than they are in young people. It has been observed that the number of drugs used increases in aging patients, especially in diabetic patients. This study aimed to investigate the relationship between polypharmacy and modified Charlson Comorbidity Index (CCI) and Katz Index of Independence in Activities of Daily Living (Katz ADL) scores in aging diabetic and non-diabetic patients. MATERIALS AND METHODS: This prospective study included 184 diabetic and 62 non-diabetic subjects who were ≥65 years old. Comorbidity was determined with CCI, and dependency on daily basic activities was assessed with Katz ADL. RESULTS: CCI and the number of drugs were significantly higher in diabetic groups (P = .001). In all subjects and in the diabetic group, there was a negative correlation between CCI and Katz ADL (r = -0.343, P = .001; r = -0.383, P = .001, respectively); there was a positive correlation between CCI and number of drugs (r = 0.430, P = .001; r = 0.248, P = .001, respectively). CONCLUSION: We found an increase in the number of drugs taken by the aging patients, positively correlated with the CCI score. The increase in the number of drugs used is closely related to the insufficiency in daily life activity and comorbidity, and this predicts 10-year survival. Patients should be directed to special centers or physicians who will be scheduled for multidisciplinary treatment for the prevention of polypharmacy, especially in the aging.
RESUMEN
OBJECTIVE: Inflammation plays a crucial role in the pathogenesis and clinical outcome of atherosclerosis. Among the various inflammatory factors, antimicrobial peptides, such as alpha-defensins, seem to contribute to the development and progression of atherosclerosis. The aim of this study was to evaluate the plasma levels of human neutrophil peptide-1, -2, and -3 (HNP1-3) in patients with acute myocardial infarction (AMI) and to assess its relationship with the severity of coronary artery disease. METHODS: lasma HNP1-3 levels in patients with AMI and controls with angiographically normal coronary arteries were measured by solid-phase enzyme-linked immunosorbent assay. In the patient group, coronary artery disease severity was assessed using the SYNergy between percutaneous intervention with TAXus and cardiac surgery score (SS). RESULTS: HNP1-3 levels were significantly higher in the group with AMI than in the controls (6.5±5.8 ng/mL vs. 2.8±2.5 ng/mL, p<0.001). The receiver operator characteristic (ROC) analysis yielded a cut-off value of 3.13 ng/mL for differentiating patients with AMI from the controls (area under the curve: 0.739, 95% confidence interval: 0.629-0.831, p<0.001). HNP1-3 levels in the high SS tertile (≥33) were slightly but statistically nonsignificantly higher than that in the low (≤22) and intermediate SS tertiles (high SS: 7.0±6.1 ng/mL, intermediate SS: 5.9±6.2 ng/mL, low SS: 5.3±3.8 ng/mL; p=0.639). CONCLUSION: Patients with AMI had higher plasma HNP1-3 levels than the controls, but this did not show a significant correlation with angiographic disease severity. The nonsignificant trend toward higher SS in patients with higher HNP1-3 levels warrants future studies on larger populations.

BACKGROUND: To see the relationship of early admission parameters with the type of stroke and/or with the 30-days mortality from this disease. METHODS: Stroke patients at their early hyperacute phase (n = 180) were enrolled in this study (156 ischemic strokes and 24 hemorrhagic strokes). Blood levels of C-reactive protein (CRP), testosterone, and estradiol were determined at admission, before any specific intervention. Patients' clinical data, including the above-mentioned laboratory parameters, were compared between the above two stroke types (in total and between sexes). RESULTS: The mean age of the patients was 69.55 ± 12.03 years old (69.92 ± 11.94 years old in ischemic stroke and 67.12 ± 12.54 years old in hemorrhagic stroke). Serum estradiol levels of both males of ischemic stroke and females of hemorrhagic stroke patients were significantly higher than the females of the ischemic stroke. Serum CRP levels of both females and males of the hemorrhagic group were higher than their peers of the opposite group. Early admission serum CRP level ≥ 0.74 mg/dL in males helped predict hemorrhagic stroke while a serum estradiol level ≥ 14.07 ng/mL helped predict the same type of stroke in females. CONCLUSIONS: Our study results show that simple early laboratory measures (such as CRP and estradiol) may help in the early phase management of stroke. Further studies are needed to confirm our findings.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has quickly turned into a global pandemic with close to 5 million cases and more than 320,000 deaths. Cancer patients constitute a group that is expected to be at risk and poor prognosis in COVID pandemic. We aimed to investigate how cancer patients are affected by COVID-19 infection, its clinical course and the factors affecting mortality. METHODS: In our single-center retrospective study, we included cancer patients with laboratory confirmed COVID-19 in our hospital. Demographic, clinical, treatment, and laboratory data were obtained from electronic medical records. Logistic regression methods were used to investigate risk factors associated with in-hospital death. RESULTS: In the hospital, 4489 patients were hospitalized with COVID infection and 77 were cancer patients. The mean age of cancer patients was 61.9 ± 10.9 and 44 of them were male (62%). While the mortality rate in non-cancer patients was 1.51% (n = 68), this rate was significantly higher in cancer patients, 23.9% (n = 17). The stage of the disease, receiving chemotherapy in the last 30 days also lymphopenia, elevated troponin I, D-dimer, CRP, and CT findings were associated with severe disease and mortality. Severe lung involvement (OR = 22.9, p = 0.01) and lymphopenia (OR = 0.99, p = 0.04) are the most important factors influencing survival in logistic regression. CONCLUSIONS: The disease is more severe in cancer patients and mortality is significantly higher than non-cancer patients. These data show that it may be beneficial to develop dynamic prevention, early diagnosis and treatment strategies for this vulnerable group of patients who are affected by the infection so much.
RESUMEN
INTRODUCTION: Although most ischaemic strokes are due to cardioembolism, about 25-40% of strokes are cryptogenic. Patent foramen ovale has been associated with cryptogenic stroke; however, the precise mechanism of this association has not been demonstrated. The aim of this study was to evaluate the association between inflammatory markers and cryptogenic stroke in patients with patent foramen ovale. MATERIAL AND METHODS: We included 206 patients with patent foramen ovale. Ninety-four (45.63%) out of 206 patients had had stroke, and 112 (54.37%) had not had stroke. The ratio of the total neutrophil count to the total lymphocyte count was defined as the neutrophil to lymphocyte ratio, and the ratio of the absolute platelet count to the absolute lymphocyte count was determined as the platelet to lymphocyte count. RESULTS: The neutrophil to lymphocyte ratio was significantly higher in patients who had stroke than in those who did not (2.41 ±1.69 vs. 2.19 ±1.74, p = 0.047). Although the platelet to lymphocyte count was also higher in patients who had had stroke than in those who had not, it was not statistically significant (120.94 ±55.45 vs. 118.01 ±52.21, p = 0.729). 1.62 was the cut-off value for neutrophil to lymphocyte ratio to be associated with stroke with 73.4% sensitivity and 45.05% specificity (p = 0.042). CONCLUSIONS: This study demonstrated that elevated neutrophil to lymphocyte ratio and platelet to lymphocyte count could be associated with cryptogenic stroke in patients with patent foramen ovale.
