RESUMEN

BACKGROUND: This study investigates the safety evaluation of enterocin-producing 11 E. mundtii and two E. faecium strains previously isolated from small livestock colostrums. Enterococcus species do not possess Generally Recognized as Safe (GRAS) status. Hence, it is critical to scrutinize enterococci's antibiotic resistance, virulence characteristics, and biogenic amine production capabilities in order to assess their safety before using them as starter or adjunct cultures. RESULTS: Enterococcus strains showed susceptibility to medically significant antibiotics. Multiple-drug resistance (MDR) was found in only E. faecium HC121.4, and its multiple antibiotic resistance (MAR) index was detected to be 0.22. The tetL and aph(3')-IIIa were the most commonly found antibiotic resistance genes in the strains. However, E. mundtii strains HC56.3, HC73.1, HC147.1, and E. faecium strain HC121.4 were detected to lack any of the antibiotic resistance genes examined in this study. Only E. mundtii HC166.3 showed hemolytic activity, while none of the strains engage in gelatinase activity. The strains were identified to have virulence factor genes with a low rate. None of the virulence factor genes could be detected in E. mundtii HC26.1, HC56.3, HC73.1, HC165.3, HC166.8, and E. faecium HC121.4. The E. mundtii HC73.2 strain displayed the highest presence of virulence factor genes, namely gelE, efaAfs, cpd, and ccf. Similarly, the E. mundtii HC112.1 strain showed a significant presence of genes efaAfm, ccf, and acm. There was no decarboxylation of histidine, ornithine, or lysine seen in any of the strains. Nevertheless, E. faecium HC121.4 and HC161.1 strains could decarboxylate tyrosine, but E. mundtii HC26.1, HC56.3, HC73.1, HC73.2, HC112.1, HC147.1, HC155.2, HC165.3, HC166.3, HC166.5, and HC166.8 strains only showed a limited capacity for tyrosine decarboxylation. None of the strains possessed the hdc, odc, or ldc genes, but all of them had the tdc gene. CONCLUSION: The E. mundtii HC56.3 and HC73.1 strains were deemed appropriate for utilization in food production. Using the remaining 11 strains as live cultures in food production activities could pose a possible risk to consumer health.

RESUMEN

This methodological study aimed to assess the validity and reliability of the Turkish version of the Evaluation of the Impact of Hearing Loss in Adults (ERSA) questionnaire for individuals with treated hearing loss. The study involved 200 participants, and both exploratory factor analysis and confirmatory factor analysis were used to examine structural validity. External validity was assessed by correlating ERSA scores with the Abbreviated Profile of Hearing Aid Benefit (APHAB). Internal consistency and test-retest reliability were evaluated using Cronbach's alpha and the intraclass correlation coefficient, respectively. The Turkish ERSA demonstrated strong psychometric properties, with significant correlations between APHAB and ERSA scores and excellent internal consistency and test-retest reliability. The findings suggest that the Turkish ERSA is a valid and reliable tool for evaluating the impact of hearing loss in individuals.

RESUMEN

OBJECTIVE: To detect changes in body temperature during outpatient procedures and to identify factors associated with hypothermia in the paediatric population undergoing radiotherapy under sedation. METHODS: The observational study was conducted between July and October 2022 at Ankara City Hospital, Turkey, and comprised paediatric cancer patients aged from 1 month to 18 years who needed sedation or general anaesthesia during radiotherapy. Baseline body temperature T1 was measured before transportation to the radiotherapy room, while body temperature T2 was taken after radiotherapy. Data was analysed using SPSS 20. RESULTS: A total of 152 radiotherapy sessions related to 13 children were evaluated. There were 8(61%) boys and 5(38%) girls with overall mean 4.46±3.45 years (range: 2-13 years). The mean body surface area as 0.70±0.212. Radiotherapy was performed in 9(69%) patients, while 4(31%) patients underwent tomotheraphy. The dose used was 180cGy in 12(92.3%) patients. Hypothermia was observed in at least one session in 12(92.3%) patients. There was significant difference in body temperature at baseline and post-radiotherapy (p<0.05). CONCLUSIONS: There were significant changes in body temperature during outpatient procedures in the paediatric population undergoing radiotherapy under sedation.

RESUMEN

Background: This study aimed to evaluate acute toxicity and oncological outcomes of breast cancer patients who underwent adjuvant radiotherapy (RT) with tomotherapy. Materials and methods: The results of 114 patients who underwent adjuvant RT with Tomotherapy device between 17.08.10-12.06.2021 in Ankara Atatürk Training and Research Hospital and Ankara City Hospital were evaluated retrospectively. The primary endpoint of the study was acute adverse events, and the secondary endpoints were overall survival (OS) and disease-free survival (DFS). Results: The results of 103 patients who met the inclusion criteria were analyzed. The median follow-up was 21 (range 1-125.8) months. Grade +3 esophagitis was not observed in any patient; no esophagitis was observed in 60 (58.3%) patients. Grade 3 dermatitis was observed in 3 (2.9%) patients. In addition, dermatitis was not observed in 47 (45.6%) patients. The relationship between chest wall volume and esophagitis development was statistically significant (p = 0.006; Z score: -2769). The median OS was 24.1 (range 1-128.5) and median disease-free survival was 21.1 (range 1-125.8) months. Five patients (4.9%) died and 9 patients (8.7%) relapsed. Local recurrence was observed in only 1 (1%) patient. There was a statistically significant correlation between OS and contralateral lung V20 dose [p < 0.001; Spearman Correlation Coefficient (SCC) -406) and heart mean dose (p < 0.001; SCC -370)]. There was a statically significant correlation between DFS and cN (p < 0.001); pN (p < 0.001); heart mean dose (p < 0.001; SCC -351); contralateral lung V5 dose (p = 0.041; SCC -213); contralateral lung V20 dose (p < 0.001; SCC -434). Conclusion: Acute toxicity results show improvement in breast cancer adjuvant radiotherapy with helical tomotherapy.

RESUMEN

The apelinergic system plays an important role in the modulation of the cardiovascular system via the apelin peptide and the apelin receptor (APJ receptor). Apelin and elabela, also known toddler, are peptide ligands for the apelin receptor. These two peptides show similar biological actions, such as vasodilatation, increased myocardial contractility, angiogenesis, and energy metabolism. However, the serum levels of elabela in patients with hyperthyroidism are not well known. The aim of this study was to investigate the changes in serum elabela levels in patients with hyperthyroidism and its association with hypertension. This cross-sectional study included 74 patients with newly diagnosed hyperthyroidism due to Graves' disease and 20 healthy individuals. Serum elabela levels were measured by enzyme-linked immunosorbent assay. The patients were divided into two groups: hyperthyroid patients without hypertension (n = 51) and those with hypertension (n = 23). Basal heart rate, serum glucose and high-sensitive C reactive protein were significantly higher in hyperthyroid patients with and those without hypertension than in healthy controls (p < 0.05 for each). Serum elabela levels were significantly elevated in hyperthyroid patients compared with healthy controls, with higher serum elabela levels found in hyperthyroid patients with hypertension than those without hypertension. Linear regression analysis showed that serum elabela levels were correlated with systolic blood pressure (p < 0.001). In conclusion, serum elabela levels were significantly increased in patients with hyperthyroidism, especially in hyperthyroid patients with hypertension. Elevation in serum elabela levels may contribute to alleviation of cardiovascular complications of hyperthyroidism and hypertension.

RESUMEN

In 2013, an oropharyngeal tularemia outbreak in Turkey affected 55 persons. Drinking tap water during the likely exposure period was significantly associated with illness (attack rate 27% vs. 11% among non-tap water drinkers). Findings showed the tap water source had been contaminated by surface water, and the chlorination device malfunctioned.

RESUMEN

Aim: In our study, we aimed to investigate the Achilles tendon thickness (ATT) and asprosin levels in patients with polycystic ovary syndrome (PCOS) and to evaluate the relationship of these parameters, which may be related to cardio-metabolic diseases. Methods: In our prospective cross-sectional study, 45 female patients with PCOS and 30 female healthy individuals similar in age were included. Serum dehydroepiandrosterone sulfate (DHEAS), total testosterone, anti-Müllerian hormone (AMH) and asprosin levels were measured using appropriate kits and homeostatic model assessment of insulin resistance (HOMA-IR), luteinizing hormone (LH) to follicle-stimulating hormone (FSH) ratio was calculated. ATT measurements were performed by two radiologists using a high-resolution ultrasound doppler system. Results: Serum DHEAS, total testosterone, AMH and asprosin levels, HOMA-IR value, LF/FSH ratio, and ATT values were higher in patients with PCOS compared to healthy controls. Correlation analysis was performed between ATT and other parameters in patients with PCOS. In univariate analysis, parameters associated with ATT were detected as asprosin, DHEAS and AMH. In the linear regression analysis performed with significant parameters, asprosin and DHEAS levels were found to be associated with ATT. Conclusion: ATT values and serum asprosin levels were found to be significantly increased in patients with PCOS, and there is a very close positive relationship between ATT and serum asprosin levels. For this reason, it was thought that ATT measurement could be a cheap, simple and non-invasive monitoring parameter that can be used in the routine cardiometabolic follow-up of patients with PCOS.

RESUMEN

OBJECTIVE: High levels of insulin-like growth factor 1 (IGF-1) in patients with acromegaly cause structural and functional changes specific to the disease. These changes lead to mortality if the disease is not treated. Circadian blood pressure (BP) rhythm as measured by 24-h ambulatory blood pressure monitoring (ABPM) can change with a decrease in BP during sleep and a sudden increase in wakefulness. AIM: We aim to evaluate the relationship between changes in BP and IGF-1 levels in patients with acromegaly. METHODS: Patients who were diagnosed with acromegaly and the patient group with hypertension were included. Serum biochemistry parameters, serum IGF-1 level and ABPM follow-ups were compared in these patients. RESULTS: In our study, 30 patients with acromegaly and 30 patients with hypertension without acromegaly were included. Thirty of the patients were male and 30 were female. There was a statistically significant difference between the groups in terms of IGF-1(p = < 0.001) and GH(p = 0.004). There was no significant difference between patients' office systolic/diastolic BP measurements, day/night, systolic/diastolic BP measurements and all systolic/diastolic BP measurements in ambulatory blood pressure follow-ups. There was a significant difference in morning blood pressure surge(p = < 0.001). A statistically significant difference was found between the acromegaly patient groups with MBPS below and above 25 mmHg in terms of IGF-1 (p = 0.025) and platelet levels (p = 0.004). CONCLUSION: As a result, cardiovascular disease risks can be predicted in patients with high serum IGF-1 levels by planning ambulatory blood pressure in the early period.

RESUMEN

BACKGROUND AND AIM: The use of therapeutic plasma exchange (TPE) for treatment of hypertriglyceridemia-induced acute pancreatitis (HTGP) remains controversial in the literature. This study compared the clinical outcomes of TPE versus conventional therapy in patients with HTGP. METHODS: Fifty-five patients with HTGP were included. Patients were retrospectively compared in pairs: those who received TPE treatment and those who did not, those whose triglyceride level fell below 500 mg/dL within 48 h, and those who did not, those with and without persistent organ failure. The primary outcome was the percentage of triglyceride reduction within 48 h. Secondary outcomes were the length of hospital stay, mortality, cost-effectiveness, and persistent organ failure. RESULTS: Percentage decrease in triglyceride levels, medical hospitalization costs, and length of hospital stay were higher in the TPE group compared to the non-TPE group (p < 0.05, for each). However, there was no difference regarding persistent organ failure and mortality (p > 0.05, for each). The length of hospital stay, average cost, persistent organ failure, and mortality were similar in both groups whose triglyceride level fell below 500 mg/dL within 48 h and those who did not (p > 0.05, for each). Among patients with persistent organ failure, average cost was higher in the TPE group compared to the non-TPE group (p < 0.05). An independent relation was found between the average cost and persistent organ failure, TPE, length of hospital stay, albumin, and urea values in all patients (p < 0.05, for each). CONCLUSIONS: The approach of using TPE for treatment of HTGP was not found to be superior to the conventional treatment. Randomized controlled studies with larger number of patients are needed to gain better understanding of this issue.

RESUMEN

BACKGROUND: Hypermagnesemia is one of the vital electrolyte disturbances and is associated with such chronic conditions as cardiovascular, endocrinologic, renal diseases, and malignancy. AIM: This study evaluates the association between hypermagnesemia and clinical course in hospitalized patients. METHODS: This study was conducted at the University of Health Sciences Haseki Training and Research Hospital Internal Medicine Clinic. We evaluated a total of 3850 patients. 2130 patients have met the inclusion criteria were included in the study. Those who were discharged with healing were evaluated as having a good prognosis. Patients who died or were transferred to the intensive care unit (ICU) were defined as having a poor prognosis. We divided the patients' serum magnesium levels into four quartiles and examined the clinical course/conditions of the patients. RESULTS: Of 2130 patients, 1013 (51.9%) were female. The mean age of patients with poor prognoses (69.2 ± 14.9) was higher than those with good prognoses (59.7 ± 19.1). Hypermagnesemia (4th quartile) was detected in 61 (33.9%), and hypomagnesemia (1st quartile) was found in 42 (23.3%) patients out of 180 patients with poor clinical outcomes. It was statistically significant that hypermagnesemia was more common in patients with poor prognoses (p: 0.002). Chronic kidney disease (CKD) was diagnosed in 258 (53.3%) of 484 hypermagnesemia patients. Hypermagnesemia was found to be more common in patients with CKD, which was statistically significant (p: 0.003). CONCLUSIONS: Hypermagnesemia is associated with poor prognosis independent of comorbidities. Besides hypomagnesemia, hypermagnesemia should be considered a critical electrolyte imbalance.

RESUMEN

BACKGROUND: Bariatric surgery is a treatment with a low risk of complications that is becoming common in obesity treatment. OBJECTIVE: The aim of this study is to evaluate postoperative visits to the emergency department by patients who underwent bariatric surgery and to investigate what postoperative conditions are encountered in these patients and what can be done to prevent emergency room admission and hospitalization. SETTING: University Hospital. METHODS: The study included 394 patients aged 18 years underwent bariatric surgery for obesity. Emergency department (ED) admissions and diagnoses of patients who underwent bariatric surgery were analyzed in two groups, surgery-related and surgery-unrelated. RESULTS: It was found that 22% (n: 87) of patients visited the ED at least once; 4.8% (n: 19) of them were hospitalized; and 78.1% (n: 68) of 87 patients did not need to be hospitalized. Low preoperative iron, folic acid, and ferritin levels increase the number of visits to ED with a bariatric surgery-related complaint, urinary tract infection was the most common diagnosis and did not require hospitalization; the most common diagnosis of hospitalized patients was gastrointestinal perforation, pulmonary embolism, intra-abdominal abscess. CONCLUSION: Despite the low risk of complications, bariatric surgery is a surgery associated with a high number of preventable postoperative emergency visits. ED visits can be reduced by calling these patients for more frequent outpatient check-ups, providing intravenous hydration therapy in outpatient clinics and, if necessary, providing prescribed treatment.

RESUMEN

AIM: To investigate the therapeutic and neuroprotective effects of transcranial direct current stimulation (tDCS) application on the traumatic brain injury (TBI)-induced glutamate and calcium excitotoxicity and loss of motor and cognitive functions. MATERIAL AND METHODS: Forty rats were equally divided in the sham, TBI, tDCS + TBI + tDCS, and TBI + tDCS groups. Mild TBI was induced by dropping a 450-g iron weight from a height of 1 m onto the skull of the rats. The tDCS + TBI + tDCS group was prophylactically administered 1 mA stimulation for 30 min for 7 days starting 5 days before inducing TBI. In the TBI + tDCS group, tDCS (1 mA for 30 min) was administered 2 h after TBI, on days 1 and 2. Cognitive and locomotor functions were assessed using the novel object recognition and open field tests. The calcium, glutamate, and N-methyl-D-aspartate receptor 1 (NMDAR1) levels in the hippocampus were measured using enzyme-linked immunosorbent assay. RESULTS: Although the motor and cognitive functions were substantially reduced in the TBI group when compared with the sham, they improved in the treatment groups (p < 0.05). The calcium, glutamate, and NMDAR1 levels were considerably higher in the TBI group than in the sham (p < 0.001). However, they were considerably lower in the tDCS + TBI + tDCS and TBI + tDCS groups than in the TBI groups (p < 0.05). In particular, the change in the tDCS + TBI + tDCS group was higher than that in the TBI + tDCS group. CONCLUSION: Application of tDCS before the development of TBI improved motor and cognitive dysfunction. It demonstrated a neuroprotective and therapeutic effect by reducing the excitotoxicity via the regulation of calcium and glutamate levels.

RESUMEN

BACKGROUND: Asprosin is an emerging biomarker that plays a role in metabolic diseases. This study investigates asprosin as a predictive marker for coronary artery disease (CAD) severity in diabetic patients. METHODS: Diabetic patients (n = 181) and healthy controls (n = 60) were analyzed. CAD severity was assessed using SYNTAX score. Diabetic patients were divided into 3 groups. Group 1 = patients without CAD, group 2 = patients with low SYNTAX score, and group 3 = patients with moderate-high SYNTAX score. Asprosin levels were measured for all participants using an enzyme-linked immunosorbent assay (ELISA). RESULTS: Asprosin levels were significantly higher in patient group compared to control group (p < 0.001). Asprosin levels were significantly higher in group 3 compared to group 1 and group 2 (p = 0.002). In logistic regression analysis, asprosin levels independently predicted patients with moderate-high SYNTAX scores. According to this analysis, 1 ng/mL increase in asprosin level was found to increase the risk of having moderate-high SYNTAX score by 14.1%. When the threshold value of asprosin level was set as 22.17 ng/mL, it predicted patients with moderate-high SYNTAX score with 63.6% sensitivity and 62.6% specificity. In multivariate regression analysis, SYNTAX score independently correlated with asprosin level. CONCLUSION: This is the first study in the literature to demonstrate a positive correlation between asprosin levels and SYNTAX scores in diabetic patients with CAD. More comprehensive studies with larger groups are needed.

RESUMEN

Background/Objectives: Acute pancreatitis (AP) is characterized by pancreatic gland inflammation, and its clinical course ranges from mild to severe. Predicting the severity of AP early and reliably is important. In this study, we investigate the potential use of the Controlling Nutritional Status (CONUT) score as a prognostic marker in acute pancreatitis. Methods: We examined 336 patients who had been hospitalized with an AP diagnosis in the internal medicine clinic. The patients included in the study were followed up for 5 years. The study analyzed the specific variables of age, gender, and AP etiology as recorded biochemical parameters for all study participants and calculated the effects of age, sex, Bedside Index of Severity in AP (BISAP), the revised Atlanta classification, and the CONUT score on mortality. Results: When compared with surviving patients, non-surviving patients had higher scores for BISAP, CONUT, and the Atlanta Classification (p ˂ 0.001). In the non-surviving group, hemoglobin, lymphocyte, and albumin levels were significantly lower and creatinine, uric acid, and procalcitonin levels were significantly higher compared to the surviving group (p ˂ 0.001, 0.003, ˂0.001, ˂0.001, 0.005, ˂0.001, respectively). The multivariate analysis showed a significant association of mortality with age, CONUT, and BISAP scores (p ˂ 0.003, 0.001, 0.012 respectively). The CONUT score was separated into two groups based on the median value. The predicted survival time in the group with a CONUT score > 2 (53.8 months) was significantly lower than in the group with a CONUT score ≤ 2 (63.8 months). The cumulative incidence of all-cause mortality was significantly higher in the patients with higher CONUT scores. Conclusions: This study has assigned the CONUT score as an independent risk factor for mortality in AP.

RESUMEN

Enterococci are lactic acid bacteria (LAB) that play a role in the aroma formation, maturation, and sensory development of fermented foods such as meat and dairy products. They also contribute to the improvement of the extended shelf life of fermented foods by producing bacteriocin. The aim of this study was to isolate bacteriocin-producing LAB from sheep and goat colostrum, to characterize the bacteriocin-producing strains, and determine the technological properties of the strains. A total of 13 bacteriocin-producing LAB was isolated and identified as 11 Enterococcus mundtii and two Enterococcus faecium. The strains were found to be genetically different from each other by phylogenetic analysis of 16S rRNA gene sequences and random amplified polymorphic-DNA (RAPD-PCR). It has been determined that bacteriocins show activity in a wide pH range and are resistant to heat, lose their activity with proteolytic enzymes and α-amylase, but are resistant to detergents. While the presence of the munKS gene was detected in all of the strains, it was determined that E. faecium HC121.4, HC161.1, E. mundtii HC147.1, HC166.5, and HC166.8 strains contained multiple enterocin genes. Trisin-SDS-PAGE analysis revealed two active protein bands of approximately 5.1 and 5.5 kDa in E. faecium HC121.4 and one active protein band with a weight of approximately 4.96 kDa in other strains. E. mundtii strains and E. faecium HC161.1 were identified as mundticin KS producers, and E. faecium HC121.4 was defined as an enterocin A and B producer. Except for E. mundtii HC166.8, acid production of strains was found to be slow at 6 h and moderate at 24 h. None of them showed extracellular proteolytic and lipolytic activities. It was found that the strains had esterase, esterase lipase, leucine arylamidase, acid phosphatase, and naphthol-AS-Bl-phosphohydrolase activities, while protease activities were low and peptidase activities were high. In conclusion, bacteriocin producer 13 Enterococcus strains isolated from sheep and goat colostrum were found to have the potential to be included in starter culture combinations.

RESUMEN

Ventricular tachycardia (VT) is an important type of arrhythmia with a risk of sudden death. Although implanted cardiac defibrillation and radiofrequency ablation are used together with medical treatments for VT, the treatment options are limited in cases that do not respond to them. Stereotactic ablative body radiotherapy (SABR) applied to VT substrates in resistant cases is an emerging treatment with positive results. Such clinical results have increased the interest in this subject. However, the ideal treatment device and method have not yet been described for this therapy, which is generally applied at a single fraction using various devices and methods. Herein, treatment planning was conducted for a total of 8 patients (11 VT substrates) using the Varian TrueBeam EDGE and TomoTherapy Radixact devices at a single center, and the results were compared dosimetrically. The Wilcoxon-signed rank test was used for the statistical analysis, and mean values were expressed as medians and interquartile ranges (IQRs). In the volumetric modulated arc therapy (VMAT) and helical tomotherapy (HT) plans, the plan coverages and conformity indexes were similar; meanwhile, the homogeneity indexes were 0.10 (IQR = 0.05) and 0.07 (IQR = 0.05), respectively, and were significantly better in the HT plan (p = 0.02). The gradient indexes were 3.18 (IQR = 0.8) and 5.33 (IQR = 3.68) in the VMAT and HT plans, respectively, and were significantly better in the VMAT plan. For the organs at risk, similar doses were observed. The maximum doses for the stomach and esophagus and the mean doses for the left lung and both lungs were significantly lower in the VMAT plan. Similarly, the maximum and mean doses for the cardiac substructures and great vessels were significantly lower in the VMAT plan. More homogeneous plans were obtained in HT, while a faster dose reduction and lower critical organ dose were observed in VMAT. Reasonable myocardial SABR plans could be obtained with both techniques. The effects of the dosimetric differences on the clinical outcomes should be evaluated in prospective clinical studies.

RESUMEN

Nephrotic syndrome progresses with various metabolic disturbances, such as proteinuria over 3.5 grams in 24 hours, hypoalbuminemia, and hypercoagulability. Patients usually complain about diffuse edema throughout the body, which is secondary to hypoalbuminemia. It has many primary and secondary causes. Patients may require a renal biopsy to confirm the diagnosis. Besides, many secondary causes of nephrotic syndrome should be examined and excluded. Although many vaccines were developed due to the COVID-19, many side effects are still reported because of the Pfizer-BioNTech COVID-19 vaccine (COVID-19 mRNA and BNT162b2), which is widely used in Turkey. This study examines a case of nephrotic syndrome with acute renal injury after Pfizer-BioNTech vaccine.

RESUMEN

Purpose: Internal medicine services serve the patient population with many chronic diseases. Therefore, it is high mortality rates compared to other departments of the hospital. Estimating the prognostic risk of hospitalized patients may be useful in mortality for patients. In this study, we evaluated the level of Systemic Immune Inflammation Index (SII) and Systemic Inflammation Response Index (SIRI) and its association with mortality in inpatients. Patients and methods: This study was performed in 2218 patients who were hospitalized between January 1st-December 31th of 2019. Patients were followed up for three years about primary endpoint as all-cause (except for unnatural deaths) mortality. Participants were divided into 4 equal groups according to their increasing levels of SII and SIRI. (Quartile 1-4) Age, gender, diabetes mellitus, hypertension, coronary artery disease, chronic kidney disease, malignancies (solid), white blood cell, neutrophil, lymphocyte, monocytes, hemoglobin, hematocrit, platelet, CRP, albumin, Systemic Inflammation Response Index (Quartile 1-4), Systemic Immune Inflammation Index (Quartile 1-4) were compared between survival and non-survival groups. Results: There were 1153 female and 1065 male participants enrolled. Compared with surviving patients, patients who died were older and had a higher prevalence of diabetes mellitus, hypertension, malignancy, chronic kidney disease and coronary artery disease (p < 0.001). There was a lower proportion of female patients among the patients who died. Compared to the survivor group, group who died exhibited a significant increase in CRP level, neutrophil, white blood cell and monocyte counts, but had a lower lymphocyte count, albumin level and hemoglobin count (P < 0.001). Results of Cox regression analysis showed that age, chronic kidney disease, malignancy, SIRI quartile 3, 4 and SII quartile 3, 4 pointed out a close relationship with mortality risk. (P < 0.001). Conclusion: The SIRI and SII have indicated the clinical importance of as novel markers for predicting mortality in inpatients.

RESUMEN

BACKGROUND: Stereotactic body radioablation therapy (SBRT) has recently been introduced with the ability to provide ablative energy noninvasively to arrhythmogenic substrate while reducing damage to normal cardiac tissue nearby and minimizing patients' procedural risk. There is still debate regarding whether SBRT has a predominant effect in the early or late period after the procedure. We sought to assess the time course of SBRT's efficacy as well as the value of using a blanking period following a SBRT session. METHODS: Eight patients (mean age 58 ± 14 years) underwent eight SBRT sessions for refractory ventricular tachycardia (VT). SBRT was given using a linear accelerator device with a total dose of 25 Gy to the targeted area. RESULTS: During a median follow-up of 8 months, all patients demonstrated VT recurrences; however, implantable cardioverter-defibrillator (ICD) and anti-tachycardia pacing therapies were significantly reduced with SBRT (8.46 to 0.83/per month, p = 0.047; 18.50 to 3.29/per month, p = 0.036, respectively). While analyzing the temporal SBRT outcomes, the 2 weeks to 3 months period demonstrated the most favorable outcomes. After 6 months, one patient was ICD therapy-free and the remaining patients demonstrated VT episodes. CONCLUSIONS: Our findings showed that the SBRT was associated with a marked reduction in the burden of VT and ICD interventions especially during first 3 months. Although SBRT does not seem to succeed complete termination of VT in long-term period, our findings support the strategy that SBRT can be utilized for immediate antiarrhythmic palliation in critically ill patients with otherwise untreatable refractory VT and electrical storm.

RESUMEN

BACKGROUND: Periostin is an emerging biomarker that plays a role in bone metabolism and may be associated with bone mineral density (BMD). This study is aimed to investigate serum periostin levels in patients with primary hyperparathyroidism (PHPT) and its correlation with BMD in these patients. METHODS: Forty patients with newly diagnosed PHPT without co-morbidities and 30 healthy controls were included. Laboratory tests for the diagnosis of PHPT and serum levels of periostin were measured for all patients. BMD was measured on lumbar spines L1 and L4 by dual-energy X-ray absorptiometry (DEXA). Serum periostin levels were detected using an enzyme-linked immunosorbent assay (ELISA). RESULTS: Serum periostin levels were significantly higher in patients with PHPT than in healthy controls (p<0.001). Serum periostin levels were also significantly higher (mean 59.7±11.0 ng/mL) in PHPT patients with osteoporosis than those without osteoporosis (p=0.004). In logistic regression analysis, only serum periostin levels independently predicted the patients with osteoporosis. According to this analysis, every 1 ng/mL increase in serum periostin increased the risk of having osteoporosis by 20.6%. When the cut-off for serum periostin level was 49.75 ng/mL, the patients with osteoporosis were predicted with 71.4% sensitivity and 69.2% specificity. Multivariate regression analysis revealed a negative correlation between serum periostin levels and L1-L4 T scores on DEXA. CONCLUSION: This is the first study to determine that serum periostin levels are higher in PHPT patients than those without PHPT and to demonstrate a significant association between serum periostin levels and T scores on DEXA in patients with PHPT. These findings will aid in detecting osteoporosis in patients with PHPT and making the decision for surgery in PHPT patients with no need for DEXA imaging that involves radiation.
