RESUMEN

BACKGROUND: Migraine is associated with several genetic or acquired comorbidities. Studies conducted in recent years emphasize that the frequency of thrombophilia is high in migraine, especially migraine with aura (MA). Similarly, the presence of white matter lesions (WMLs) on brain magnetic resonance imaging (MRI) scans has been associated with migraine for many years. OBJECTIVE: Based on the knowledge that both WMLs and thrombophilia variants are frequently observed in MA, we aimed to investigate whether there is a relationship between genetic thrombophilia and the presence of WMLs in these patients. METHODS: The levels of proteins S and C, antithrombin III activities, activated protein C (APC) resistance, antiphospholipid immunoglobulin G/immunoglobulin M (IgG/IgM) and anticardiolipin IgG/IgM antibodies were investigated in 66 MA patients between the ages of 18 and 49 years who presented no cardiovascular risk factors. The presence of WMLs and the Fazekas grade was determined from the brain magnetic resonance imaging (MRI) scans' T2-weighted and fluid-attenuated inversion recovery (FLAIR) sequence taken from the patients. The rates of WMLs were compared in patients with and without thrombophilia. RESULTS: Thrombophilia was detected in 34.8% of the patients, and 27.3% were determined to have WMLs in brain MRI scans. The WMLs were detected in 23.3% of the patients without thrombophilia, in 34.8% of those with thrombophilia, and in 50% of the subjects with multiple thrombophilia disorders. Among the thrombophilia disorders, only APC resistance was significantly more common in patients with WMLs. CONCLUSION: The results of the present study showed that thrombophilia may be a mechanism that should be investigated in the etiology of increased WMLs in MA.


ANTECEDENTES: La migraña se asocia con una serie de comorbilidades genéticas o adquiridas. Los estudios realizados en los últimos años destacan que la frecuencia de trombofilia es elevada en la migraña, especialmente en la migraña con aura (MA). De manera similar, la presencia de lesiones de la sustancia blanca (LSB) en las imágenes por resonancia magnética (RM) del cerebro se ha asociado con la migraña hace muchos años. OBJETIVO: Con base en la información de que se suelen observar tanto LSB como variantes de la trombofilia en MA, nuestro objetivo fue investigar si existe una relación entre la trombofilia genética y la presencia de LSB en estos pacientes. MéTODOS: Se investigaron los niveles de proteína S y de proteína C, actividades de antitrombina III, resistencia a la proteína C activada (PCA), anticuerpos antifosfolípidos inmunoglobulina G/inmunoglobulina M (IgG/IgM) y anticuerpos anticardiolipina IgG/IgM en 66 pacientes con MA entre 18 y 49 años que no presentaban factores de riesgo cardiovascular. Se determinaron la presencia de LSB y el grado de Fazekas a partir de imágenes por RM del cerebro en la secuencia ponderada en T2 y recuperación de la inversión atenuada de fluido (fluid-attenuated inversion recovery, FLAIR, en inglés) obtenidas de los pacientes. Se compararon las tasas de LSB en pacientes con y sin trombofilia. RESULTADOS: Se detectó trombofilia en el 34,8% de los pacientes y LSB en el 27,3%. Las LSB estuvieron presentes en el 23,3% de los pacientes sin trombofilia, en el 34,8% de los que tenían trombofilia, y en el 50% de los que tenían múltiples trastornos trombofílicos. La resistencia a la PCA fue significativamente más común en aquellos pacientes con LSB. CONCLUSIóN: Los resultados del presente estudio mostraron que la trombofilia puede ser un mecanismo que debe investigarse en la etiología del aumento de LSB en MA.

RESUMEN

BACKGROUND: In this study, we aimed to investigate the clinical follow-up results of endoscopic thoracic sympathectomy (ETS) in the treatment of vasospastic angina (VSA) resistant to maximal medical therapy. METHODS: A total of 80 patients with VSA who presented to our hospital between 2010 and 2022 were included in our study. Among them, 6 patients who did not respond to medical therapy underwent ETS. In-hospital and long-term clinical outcomes of patients who underwent ETS were recorded. RESULTS: The median age of the patients with VSA was 57 [48-66] years, and 70% of the group were males. In the ETS group, compared to the non-ETS group, higher numbers of hospital admissions and coronary angiographies were observed before ETS (median 6 [5-6] versus 2 [1-3], P <.001; median 5 [3-6] versus 2 [1-3], P =.004, respectively). Additionally, while 2 patients (33.3%) in the ETS group had implantable cardioverter defib-rillator (ICD), only 2 patients (2.7%) in the non-ETS group had ICD (P =.027). Out of the 6 patients who underwent ETS, 2 were females, with a median age of 56 [45-63] years. Four patients underwent successful bilateral ETS, while 2 patients underwent unilateral ETS. During the follow-up period after ETS, only 3 patients experienced sporadic attacks (once in 28 months, twice in 41 months, and once in 9 years, respectively), while no attacks were observed in 3 patients during their median follow-up of 7 years. CONCLUSION: It appears that ETS is effective in preventing VSA attacks without any major complications.

RESUMEN

BACKGROUND: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs. METHODS AND RESULTS: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary end point was defined as the all-cause death during follow-up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P=0.549) and procedural success (73.7 versus 65.2%; P=0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in-hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75-5.88]; P=0.001; and adjusted odds ratio (inverse probability-weighted), 4.55 [95% CI, 2.27-10.0]; P<0.001). However, the long-term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59-1.25]; P=0.435; and adjusted HR (inverse probability-weighted), 1.11 [95% CI, 0.67-1.81]; P=0.679). CONCLUSIONS: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long-term mortality rates compared with surgery.

RESUMEN

OBJECTIVE: Obesity is a global health problem that increases the risk of coronary artery disease (CAD). However in studies, it has been observed that when the disease develops, obese patients have a more favorable prognosis than leaner patients. This is called the "obesity paradox." This study aims to evaluate the effect of obesity assessed with body fat percentage (BFP) and relative fat mass (RFM) besides body mass index (BMI) on infarct size (IS) estimated from peak creatine kinase-MB (CK-MB) levels in patients with non-ST-segment elevation myocardial infarction (NSTEMI). METHODS: Patients with a diagnosis of NSTEMI who underwent coronary angiography between January 2017 and January 2022 were retrospectively evaluated. Patients without available anthropometric data to calculate BMI, BFP, and RFM and serial CK-MB measurements were excluded from the study. BMI was calculated using weight(kg)/(height[m])2 formula. Patients were dichotomized as obese (BMI≥30 kg/m2) and non-obese (BMI<30 kg/m2) to compare baseline characteristics. BFP and RFM were calculated from anthropometric data. Linear regression analysis was performed to define predictors of IS. RESULTS: Final study population consisted of 748 NSTEMI patients (mean age was 59.3±11.2 years, 76.3% were men, 36.1% of the patients were obese). Obese patients were more likely to be female, hypertensive, and diabetic. Smoking was less frequently observed in obese patients. Peak CK-MB levels were similar among groups. Obese patients had higher in-hospital left ventricular ejection fraction, and less severe CAD was observed in coronary angiographies of these patients. Multivariable regression analysis identified diabetes mellitus, systolic blood pressure, white blood cell count, hemoglobin, and BFP (ß=-4.8, 95% CI=-8.7; -0.3, p=0.03) as independent predictors of IS. CONCLUSION: Higher BFP is associated with smaller IS in NSTEMI patients. These findings support the obesity paradox in this patient group, but further, randomized controlled studies are required.

RESUMEN

OBJECTIVE: Different results have been obtained in studies on the effect of anesthesia type applied during transcatheter aortic valve implantation on in-hospital outcomes. In this study, we aimed to investigate the association of the type of anesthesia with the lenght of stay in the intensive care unit and the need for inotropes in patients undergoing transcatheter aortic valve implantation. METHODS: A total of 140 patients who underwent transcatheter aortic valve implantation between January 2016 and January 2022 were retrospectively analyzed. The patients were divided into 2 groups as deep sedation and general anesthesia according to the type of anesthesia. RESULTS: The mean age of all patients was 78.5 ± 8.6 years, and 69 of the patients (49.3%) were female. Length of stay in intensive care unit, midazolam dosage, use of inotropic agents, and procedural hypotension were significantly lower in the deep sedation group than in the general anesthesia group [(1[1-2] vs. 1[1-2.5] days, P = 0.03), (2.1 ± 0.4 mg/kg vs. 2.3 ± 05, P = 0.02), (39 (37.9%) vs. 22 (59.5%), P = 0.02), (41 (39.8%) vs. 25 (67.6%), P = 0.004)]. General anesthesia was associated with increased use of inotropic agents during transcatheter aortic valve implantation compared to deep sedation (odds ratio = 2.93 95% CI = 1.18-7.30, P = 0.02). CONCLUSION: The use of inotropes is less in transcatheter aortic valve implantation procedures performed under deep sedation and length of stay in intensive care unit is shorter.

RESUMEN

OBJECT: In patients with headache, the distinction between transverse sinus (TS) atresia/hypoplasia and TS thrombosis in cranial magnetic resonance venography (MRV) may be misleading. In this study, we aimed to distinguish TS thrombosis from atretic or severely hypoplastic TS, with the help of cranial computed tomography (CT). METHOD: Non-contrast cranial CT scans of 51 patients with no or severely thin signal on MRV were analyzed retrospectively using the bone window. Absence or asymmetry of the sigmoid notches on the CT predicted atretic or severe hypoplastic TS, and symmetry predicted thrombotic TS. Afterwards, it was investigated whether the patient's other imaging findings and confirmed diagnoses matched with the predictions. FINDINGS: Of the 51 patients included in the study, 15 were diagnosed with TS thrombosis, and 36 were diagnosed with atretic/hypoplastic TS. All 36 of the congenital atresia/hypoplasia diagnoses were correctly predicted. Thrombosis was predicted correctly in 14 of 15 patients with TS thrombosis. In cranial CT, the symmetry or asymmetry of the sigmoid notch sign was examined, and it was found that the evaluation predicted with 93.3% sensitivity (95% confidence interval (CI): 68.05-99.83) and 100% specificity (95% CI: 90.26-100.00) the distinction between TS thrombosis and atretic/hypoplastic sinus. CONCLUSION: Symmetry or asymmetry of the sigmoid notch on CT is a reliable method that can be used to differentiate congenital atresia/hypoplasia from the TS thrombosis in patients with very thin or absent TS signal on the cranial MRV.

RESUMEN

BACKGROUND: Following COVID-19 infection, some patients acquired lung injury and fibrosis. Idiopathic pulmonary fibrosis is characterized by lung fibrosis. Both post-COVID lung injury and idiopathic pulmonary fibrosis cause loss of respiratory function and involvement of the lung parenchyma. We aimed to compare respiratory related functional characteristics and radiological involvement between post-COVID lung injury and idiopathic pulmonary fibrosis. METHODS: A single center, cross-sectional study was applied. Patients with post-COVID lung injury and idiopathic pulmonary fibrosis included in the study. All patients underwent the 6-minute walk test, as well as the Borg and MRC scales. Radiological images were evaluated and scored for lung parenchymal involvement. The impact of post-COVID lung injury and idiopathic pulmonary fibrosis on respiratory functions of were compared. The relationship of functional status and radiological involvement, as well as the effect of potential confounding factors were investigated. RESULTS: A total of 71 patients were included in the study. Forty-eight (67.6%) of the patients were male and the mean age was 65.4 ± 10.3 years. Patients with post-COVID lung injury had greater 6-minute walk test distance and duration, as well as higher oxygen saturations. The MRC and Borg dyspnea scores were comparable. At radiologic evaluation, ground glass opacity scores were higher in patients with post-COVID lung injury, whereas pulmonary fibrosis scores were higher in patients with idiopathic pulmonary fibrosis. However, the total severity scores were similar. While pulmonary fibrosis score was found to have a negative correlation with 6-minute walk test distance, test duration, and pre- and post-test oxygen saturation levels, there was a positive correlation with oxygen saturation recovery time and MRC score. There was no relationship between ground glass opacity and the functional parameters. CONCLUSIONS: Despite having equal degrees of radiological involvement and dyspnea symptom severity, PCLI patients exhibited higher levels of functional status. This might be due to different pathophysiological mechanisms and radiological involvement patterns of both diseases.

RESUMEN

The birth of a child is a process in which family life and daily routines undergo significant changes and adjustments. This study aims to investigate the relationship between spiritual coping styles and hope levels in mothers with disabled children. The study was conducted between January and April 2022 with mothers whose children were enrolled in a rehabilitation center of a district located in eastern Turkey. The target population of the study was 110 mothers who had children enrolled in the rehabilitation center. The sample of the study was 102 mothers who agreed to participate in the study. Data were collected through the Personal Information Form, the Trait Hope Scale, and the Maternal Spiritual Coping Scale. Spiritual coping mean scores were high in mothers who had a female disabled child, did not have any other disabled children, received support from the state for their child's care, did not ignore their other children's care due to the special condition of the disabled child and did not feel guilty, and were worried about their children's future. The difference between the mean scores was statistically significant (p < 0.05). Hope mean scores were found to be high in women who had children with physical and hearing disability, were illiterate, had a low economic condition, and received psychological support for the condition of their children. The difference between the mean scores was statistically significant (p < 0.05). A positive relationship was found between maternal spiritual coping levels and hope levels. In-line with this result, it is recommended to organize programs to help mothers to accept their children's condition and cope with their situation.

RESUMEN

PROBLEM: The research aimed to determine the relationship between internet addiction and peer bullying in sixth and seventh-grade students. METHOD: The population of the study consisted of students in the sixth and seventh grades of secondary schools in a province in eastern Turkey. The data were collected throughout the 2021-2022 academic year from 1201 sixth and seventh graders who voluntered to participate in the research. The data were collected using the Bullying Scale and the Internet Addiction Scale for Adolescents (IAA). FINDING: It was determined that gender, grade level, status of having a mobile phone, and age influenced children's participation in peer bullying. Also, variables of gender, grade level, and status of having a mobile phone affected internet addiction levels. Furthermore, when the correlation between the two scales was analyzed, a strong positive correlation was determined. CONCLUSIONS: In line with the findings of this study, interventions that may lower levels of bullying include delivering training on bullying and internet addiction to families, encouraging children to participate in activities that would reduce the amount of time they spend on the internet, and investigating the reasons for bullying.

RESUMEN

BACKGROUND: Left atrial (LA) strain is a robust measure of LA function and is a useful parameter to assess left ventricular filling pressure. While initially considered as a "load-independent" parameter of LA function, later studies have found that acute changes in LA preload may affect LA reservoir and contractile strains. Acute alterations in blood pressure (BP) induces a change in left ventricular (LV) filling pressure without imposing a volume load, thus providing an opportunity to assess the effects of the change in LA afterload on LA mechanics. This study aims to understand the effect of acute BP changes on LA strain. METHODS: A total of 40 patients admitted to the emergency department with hypertensive urgency were included. All patients underwent a comprehensive echocardiographic examination including measurement of LA reservoir, conduit and contractile strains. A repeat set of measurements were obtained after BP lowering. RESULTS: Average drop in mean BP following intervention was 18.1 ± 5.4%. LV end-systolic and end-diastolic volumes, as well as maximum and minimum LA volumes were decreased significantly after BP reduction. The absolute increases in reservoir and contractile strains were 2.3 ± 4.7% (7.9% ± 13.8% relative to baseline) and 2.5 ± 3.3% (13.5 ± 19.0% relative to baseline), respectively, with both changes being statistically significant (p = 0.003 for reservoir and p < 0.001 for contractile strains). There were no significant changes in conduit strain after BP intervention (p = 0.79). The change in both LA reservoir and contractile strains were more evident in those with a previous diagnosis of hypertension and those with a smaller degree of change in mean BP after intervention. CONCLUSION: In patients with an acute hypertension, lowering BP leads to an acute improvement in LA reservoir and contractile strains. Thus, acute changes in systemic BP should be considered when LA mechanics are evaluated.

RESUMEN

Background: Cardiohepatic syndrome (CHS) indicates a bidirectional interaction between the heart and liver. This study was designed to evaluate the impact of CHS on in-hospital and long-term mortality in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention. Materials & methods: 1541 consecutive STEMI patients were examined. CHS was defined as the elevation of at least two of three cholestatic liver enzymes: total bilirubin, alkaline phosphatase and gamma-glutamyl transferase. Results: CHS was present in 144 (9.34%) patients. Multivariate analyses revealed CHS as an independent predictor of in-hospital (odds ratio: 2.48; 95% CI: 1.42-4.34; p = 0.001) and long-term mortality (hazard ratio: 2.4; 95% CI: 1.79-3.22; p < 0.001). Conclusion: The presence of CHS is a predictor of poor prognosis in patients with STEMI and should be evaluated during the risk stratification of these patients.

RESUMEN

INTRODUCTION: Tularemia is a zoonotic disease caused by the Gram-negative coccobacillus Francisella tularensis. It is frequently overlooked in the differential diagnosis of neck masses because of its rarity. The purpose of this study is to report cases diagnosed with tularemia among patients presenting to our clinic with neck masses and to share our experience. METHODOLOGY: Patients presented to our hospital with cervical masses and diagnosed with tularemia were included in this retrospective study. Medical files of all patients were evaluated, and physical examination findings, titration values, date of diagnosis, location of the abscess or mass, place of residence, occupation, drinking water sources, sedimentation (SED), C-reactive protein (CRP), and white blood cell (WBC) values were recorded. RESULTS: Seventy-six patients were included in the study. Forty patients (52.6%) were living in rural villages and 36 (47.4%) in urban areas. Thirty-one (40.8%) were engaged in animal husbandry and 29 (38.2%) in agriculture. In terms of drinking water sources, 59 patients (73.6%) obtained water from the mains, while 10 (13.32%) used well water. The most frequently observed clinical findings were swelling in the neck, sore throat, lethargy, and fever. Neck swelling frequently occurred in levels II and III. CONCLUSIONS: Since tularemia is rare and there are no specific clinical findings, diagnosis may be problematic. Ear, nose and throat (ENT) specialists should be familiar with the clinical symptoms of tularemia in the head and neck region and should consider a preliminary diagnosis of tularemia in the differential diagnosis of persistent neck masses.

RESUMEN

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus type-2 (SARS-CoV-2), has quickly become a global pandemic. Most multiple sclerosis (MS) patients use disease-modifying treatments (DMTs), such as immunomodulators or immunosuppressants. By targeting different types of immune cells, DMTs affect cellular and/or humoral immunity. The potential effects of DMTs on the long-term immune response to COVID-19 is not fully known. Between 16.04.2020 and 15.07.2020, a total of 34 people, 17 of whom were diagnosed with MS according to the 2010 McDonald diagnostic criteria and a control group of 17 individuals who did not have a known systemic disease who were matched according to age, gender, and COVID-19 disease severity, where all received COVID-19 diagnosis with SARS-CoV-2 PCR positivity in nasopharyngeal swab test and immune responses were measured (SARS-CoV-2 IgM and IgG antibody levels COVID 19 ELISA kit), were included in our study. Demographic data of MS patients and the control group, SARS-CoV-2 immune responses, antibody titers and disease year of MS patients, EDSS scores, disease type, and disease duration were determined. All patients were symptomatic for COVID-19. COVID-19 disease severity was divided into three groups as mild, moderate, and severe according to the clinical condition of the patient. Demographic data of MS patients and the control group, SARS-CoV-2 immune responses, antibody titers and disease year of MS patients, EDSS scores, disease type, and disease duration were determined. All patients were symptomatic for COVID-19. COVID-19 disease severity was divided into three groups as mild, moderate, and severe according to the clinical condition of the patient. According to our study results, IgG-type long-term immune responses were lower in MS patients using DMTs than in the healthy population. We hope that our study will provide insight into the COVID-19 vaccine immune responses.

RESUMEN

BACKGROUND: Blood components should be gamma-irradiated (γ-IR) in order to prevent transfusion-associated graft-versus-host disease. The aim of this study is to determine the effect of γ-IR and storage time on the exosomes released from apheresis platelet concentrates (aPC) and to investigate their impact on the maximum platelet aggregation (MPA) and hemostasis. MATERIALS AND METHODS: Eight units of aPC were included in this study. These were divided into four equal portions. Two portions were irradiated before storage while the other two were not. Thus, irradiated and non-irradiated aPC samples for storage Days 0 (D0) and 5 (D5) were obtained. Exosomes were isolated from these samples using a commercial kit and were evaluated to ascertain their parent cells by flow cytometry. For the following steps, exosomes were pooled according to their features. Pooled exosomes were then used for aggregometry and thromboelastography. RESULTS: Platelet-derived exosome (PD-EX) levels decreased in D5 compared to D0 in NI-aPC, whereas granulocyte-derived exosome (GD-EX) levels increased. Exosome pools had no effect on MPA compared to saline groups. Exosome pools decreased the time to initial fibrin formation (R), whereas they increased the rate of clot formation (α-angle) and coagulation index (CI) compared to saline groups. DISCUSSION: Storage time and γ-IR each have almost the opposite effects on PD-EX and GD-EX. Exosomes have no impact on MPA, but enhance the clot strength. The impact of exosomes on aPC quality and effectiveness can be ignored or considered as a positive effect.

RESUMEN

Manifest myocardial involvement is somewhat rare in patients with Behcet's disease (BD), although echocardiographic studies suggest that subclinical alterations in left ventricular (LV) contractility is rather common. Data on right ventricular (RV) involvement in BD is rather scarce. This study aims to determine whether RV systolic performance is affected in BD patients, and to understand the clinical and echocardiographic correlates of RV contractility in these patients. Forty-five patients who fulfilled criteria for BD and 45 age and gender matched controls were enrolled. All participants underwent a comprehensive echocardiographic examination, including deformation imaging, to characterize RV mechanics. Conventional morphologic and echocardiographic indicators of RV morphology and function were not different between groups, but RV apical strain and RV free wall strain (FWS) were significantly lower in BD patients as compared to the controls (P < 0.001 and P = 0.02, respectively). The only significant correlates of FWS were tricuspid regurgitation velocity and related indices in healthy controls, while FWS correlated with LV global longitudinal strain (GLS), morphologic measures of left and right atria and ventricles, and with conventional measures of right ventricular contractility. The relationship between FWS and GLS remained statistically significant after adjusting for other clinical and echocardiographic parameters (ß = 0.379, P = 0.01). In patients with BD, there is a subclinical alteration in RV contractility and the degree of alteration in the RV systolic performance paralleled that of LV. Thus, present results support the presence of RV involvement in these patients.

RESUMEN

OBJECTIVE: To explore the possible relationship between vitamin D and coronavirus disease-2019 in an urban population known to have relatively low vitamin D levels. METHODS: The retrospective study was conducted in Bursa, Turkey, and comprised data of 30 family health centers from March 1 to December 15, 2020, related to diagnosed inpatients of coronovairus disease-2019. The diagnosis was based on polymerase chain reaction test for severe acute respiratory syndrome coronavirus-2 infection. Vitamin D levels of these patients were obtained from previous records and compared with those without polymerase chain reaction positivity. Vitamin D levels of positive patients who survived were compared with those who died of coronavirus disease-2019. Data was analysed using SPSS 21. RESULTS: Of the 2,105 patients whose data was retrieved, 212(10%) were positive for coronavirus disease-2019, while 1,893(90%) were negative. Among the positive patients, 89(42%) were men and 123(58%) were women. The overall median age was 45 years (Q1-Q3(Q1: first quartile, Q3: third quartile): 35-56 years). Vitamin D level was not significantly different between the positive and negative patients (p>0.05). Among the positive patients, 2(0.9%) patients did not have new admissions to the designated centers and their data was excluded, 206(97.2%) survived and 4(1.9%) died. There was no significant difference in vitamin D levels between those who survived and those who died (p>0.05). CONCLUSIONS: There was no significant relationship found between vitamin D levels and coronavirus disease-2019 infection and related deaths.

RESUMEN

Background: Diabetes, hypertension, hyperlipidemia and smoking are associated with coronary artery disease and ST-elevation myocardial infarction (STEMI). However, patients without any classic risk factors have a higher mortality rate in the post-STEMI period. The aim of this study was to investigate the relationship between in-hospital mortality and creatinine/albumin ratio in patients with STEMI without modifiable risk factors. Materials & methods: All patients included in this study with a diagnosis of STEMI and who underwent primary percutaneous intervention between 2016 and 2020 were retrospectively analyzed. Patients were included in the standard modifiable cardiovascular risk factor (SMuRF) group if at least diabetes, hypertension, smoking or hyperlipidemia was present according to risk factors. Patients without these risk factors were considered the non-SMuRF group. Results: Creatinine/albumin ratio was found to be higher in non-SMuRF patients with mortality (p < 0.001). In multivariate logistic regression analysis, ejection fraction, hemoglobin and SMuRF were found to be inversely associated with in-hospital mortality (odds ratio [OR]: 0.48, 95% CI: 0.35-0.66, p < 0.001; OR: 0.70, 95% CI: 0.56-0.88, p = 0.002; OR: 0.57, 95% CI: 0.34-0.95, p = 0.03, respectively). Conclusion: The creatinine/albumin ratio can be used as a predictor of mortality in these patients; it can help identify high-risk patients beforehand.

RESUMEN

OBJECTIVE: While the coronavirus disease 2019 pandemic is an ongoing issue across the world, understanding the course of the disease is important for early diagnosis and treatment. We aimed, with this study, to determine the differences between laboratory parameters in different clinical pictures of coronavirus disease 2019. MATERIALS AND METHODS: The study included 443 patients who presented to Atatürk University Medical Faculty Hospital between March 15, 2020, and June 15, 2020, and were diagnosed with coronavirus disease 2019 upon a positive Real Time Polymerase Chain Reaction (RT-PCR) result. The hospitalized patients were divided into 4 groups based on their clinical status. The roles of these markers in determining the severity of coronavirus disease 2019 were statistically evaluated. RESULTS: A total of 443 patients with RT-PCR confirmation were included in the study. The mean age was 46.0 ± 19.1 years and 54.4% of the patients were male. According to the clinical classification, 16.3% of the cases were asymptomatic, 25.7% uncomplicated, 35.7% mild/moderate, and 22.3% severe. The first 3 most frequent symptoms were cough (21.3%), fever (17.7%), and fatigue (15.5%). Hypertension (36.1%) was the major comorbidity among the patients. During the follow-up of severe cases, 39.4% developed the need for intensive care. The overall mortality rate, on the other hand, was 4.7%. Regarding laboratory parameters, procalcitonin (PCT), serum ferritin, erythrocyte sedimentation rate, C-reactive protein, neutrophil count, D-dimer, troponin, and lactate dehydrogenase were at the highest level in the severe patient group while albumin, platelet, and lymphocyte count were found to be at the lowest level in the same group. A statistically significant difference was detected between the groups (P < .001). CONCLUSION: The increase in C-reactive protein, PCT, erythrocyte sedimentation rate, ferritin, troponin, D-dimer, lactate dehydrogenase, and neutrophil count and the decrease in albumin, platelet, and lymphocyte count are significant in the severe patient group; it has been concluded that they can be used to determine the severity of coronavirus disease 2019.
