RESUMO

BACKGROUND: One of the hallmarks of frailty in patients with severe aortic stenosis (AS) is malnutrition, for which one of the most up-to-date scoring systems is the Naples prognostic score (NPS). This study sought to investigate the predictive role of the NPS in determining mortality in patients undergoing transcatheter aortic valve replacement (TAVR) under long-term follow-up. METHODS: A total of 430 consecutive patients with symptomatic severe AS who underwent TAVR were included retrospectively. The primary endpoint of the study was the long-term all-cause mortality. The study population was divided into two groups according to the NPS value, including Group 1 (NPS 0-2) and Group 2 (NPS 3-4). RESULTS: The all-cause mortality occurred in 250 patients (62.5%) patients during a follow-up time of 40.6 (22.0-69.4) months. During the follow-up period, all-cause mortality was higher in Group 2 compared with Group 1 (87.9% vs. 42.9%, p < 0.001). Older age (p < 0.001), chronic obstructive pulmonary disease (p = 0.015), left ventricular ejection fraction (p = 0.021), and being in Group 2 (high NPS) (hazard ratio: 7.058, 95% confidence interval: 5.174-9.629, p < 0.001) were found to be independent predictors of all-cause mortality at long-term follow-up. CONCLUSION: The NPS as a malnutrition and inflammation marker in patients with severe aortic stenosis who underwent TAVR provides valuable information for all-cause mortality under long-term follow-up.

RESUMO

BACKGROUND: Double kissing (DK)-crush and T-stenting and small protrusion (TAP) techniques are gaining popularity, but the comparison for both techniques is still lacking. This study sought to retrospectively evaluate the long-term outcomes of DK-crush and TAP techniques in patients with complex bifurcation lesions. METHODS: A total of 255 (male: 205 [80.3%], mean age: 59.56 ± 10.13 years) patients who underwent coronary bifurcation intervention at a single-center between January 2014 and May 2021 were included. Angiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary endpoint was target lesion failure (TLF), defined as the combination of cardiac death, target vessel myocardial infarction, or clinically driven-target lesion revascularization (TLR). The regression models were adjusted applying by the inverse probability weighted (IPW) approach to reduce treatment selection bias. RESULTS: The initial management strategy was DK-crush in 152 (59.6%) patients and TAP in 103 (40.4%) cases. The SYNTAX scores (24.58 ± 7.4 vs. 24.26 ± 6.39, p = 0.846) were similar in both groups. The number of balloon (6.32 ± 1.82 vs. 3.92 ± 1.19, p < 0.001) usage was significantly higher in the DK-crush group than in the TAP group. The rates of TLF (11.8 vs. 22.3%, p = 0.025) and clinically driven TLR (6.6 vs. 15.5%, p = 0.020) were significantly lower in the DK-crush group compared to the TAP group. The long-term TLF was significantly higher in the TAP group compared to the DK-crush group (unadjusted HR: 1.974, [95% CI: 1.044-3.732], p = 0.035 and adjusted HR [IPW]: 2.498 [95% CI: 1.232-5.061], p = 0.011). CONCLUSION: The present study showed that the DK-crush technique of bifurcation treatment was associated with lower long-term TLF and TLR rates compared to the TAP technique.

RESUMO

BACKGROUND: Frailty indicates older people who are vulnerable to stressors. The relation between ultrasonographic parameters of muscle and frailty among older people has yet to be investigated. AIMS: The aim of the study is to investigate the relationship between frailty and the ultrasonographic measurements of the rectus femoris muscle (RFM). METHODS: This cross-sectional study included 301 participants who were ≥65 years. The FRAIL questionnaire assessed frailty. The thickness, cross-sectional area (CSA), fascicle length, pennation angle (PA), stiffness, and echogenicity of RFM were assessed by ultrasound. The accuracy of parameters in predicting the frailty was evaluated by ROC analysis. RESULTS: Of all 301 participants, 24.6% were frail. Pre-frail and frail participants had significantly lower thickness (p = 0.002), CSA (p = 0.009), and fascicle length (p = 0.043) of RFM compared to robust. PA was significantly lowest in frails (p < 0.001). The multivariate logistic regression analysis showed that PA values lower than 10.65 degrees were an independent predictor of frailty (OR = 0.83, 95% Cl: 0.70-0.97, p = 0.019). Results of ROC analysis demonstrated a satisfactory result between the PA and frailty (AUC = 0.692, p < 0.001). DISCUSSION: Thickness, CSA, and PA of RFM were found to be lower in frail subjects, which may indicate the changes in muscle structure in frailty. Among all parameters, lower PA values were independent predictors of frailty. These findings may indicate a novel ultrasound-based method in frailty, that is more objective and unrelated to the cross-sectional evaluation. CONCLUSIONS: Ultrasonographic measurements of RFM, especially the lower PA may predict frailty in older people. As an objective and quantitative method, PA may be used to define frailty with acceptable sensitivity.

RESUMO

OBJECTIVES: The artificial intelligence competition in healthcare at TEKNOFEST-2022 provided a platform to address the complex multi-class classification challenge of abdominal emergencies using computer vision techniques. This manuscript aimed to comprehensively present the methodologies for data preparation, annotation procedures, and rigorous evaluation metrics. Moreover, it was conducted to introduce a meticulously curated abdominal emergencies data set to the researchers. METHODS: The data set underwent a comprehensive central screening procedure employing diverse algorithms extracted from the e-Nabiz (Pulse) and National Teleradiology System of the Republic of Türkiye, Ministry of Health. Full anonymization of the data set was conducted. Subsequently, the data set was annotated by a group of ten experienced radiologists. The evaluation process was executed by calculating F1 scores, which were derived from the intersection over union values between the predicted bounding boxes and the corresponding ground truth (GT) bounding boxes. The establishment of baseline performance metrics involved computing the average of the highest five F1 scores. RESULTS: Observations indicated a progressive decline in F1 scores as the threshold value increased. Furthermore, it could be deduced that class 6 (abdominal aortic aneurysm/dissection) was relatively straightforward to detect compared to other classes, with class 5 (acute diverticulitis) presenting the most formidable challenge. It is noteworthy, however, that if all achieved outcomes for all classes were considered with a threshold of 0.5, the data set's complexity and associated challenges became pronounced. CONCLUSION: This data set's significance lies in its pioneering provision of labels and GT-boxes for six classes, fostering opportunities for researchers. CLINICAL RELEVANCE STATEMENT: The prompt identification and timely intervention in cases of emergent medical conditions hold paramount significance. The handling of patients' care can be augmented, while the potential for errors is minimized, particularly amidst high caseload scenarios, through the application of AI. KEY POINTS: • The data set used in artificial intelligence competition in healthcare (TEKNOFEST-2022) provides a 6-class data set of abdominal CT images consisting of a great variety of abdominal emergencies. • This data set is compiled from the National Teleradiology System data repository of emergency radiology departments of 459 hospitals. • Radiological data on abdominal emergencies is scarce in literature and this annotated competition data set can be a valuable resource for further studies and new AI models.

RESUMO

BACKGROUND: Foreign body aspiration (FBA) in childhood is a life-threatening condition that necessitates prompt management to prevent devastating complications. Different imaging methods are used in the diagnosis of FBA. OBJECTIVE: The aim of this study was to compare the diagnostic value and dose of microsievert wide-volume computed tomography (µSv-WV-CT) with multidetector computed tomography using an automatic exposure control system (MDCT-AEC) in children with FBA. MATERIAL AND METHODS: In this single-center cross-sectional study, 102 cases diagnosed with FBA between September 2013 and September 2021 were retrospectively evaluated. The patients were divided into 2 groups according to the diagnostic modality used: group A, µSv-WV-CT (2016-2021) and group B, MDCT-AEC (2013-2021). The diagnostic performance and radiation dose of the 2 groups were statistically compared. RESULTS: The diagnostic performance (sensitivity, specificity, positive predictive value, negative predictive value, and accuracy) of the 2 groups was similar. The mean effective radiation dose of group A was 34.89 ± 0.01 µSv, which was significantly lower than that of group B (179.75 ± 114.88 µSv) ( P < 0.001). CONCLUSION: In children with suspected FBA, µSv-WV-CT at a lower radiation dose had similar diagnostic performance to MDCT-AEC.

RESUMO

BACKGROUND: Peripheral arterial disease is a common disease all over the world. Medical treatment, percutaneous invasive treatment, and operation are the considerable options. Percutaneous treatment is a valid option with a higher patency rate. Systemic immune-inflammatory index (SII) is a formula which is calculated as neutrophil count to platelet count divided into lymphocyte count. This formula demonstrates the active inflammatory state. In our study, we aimed to demonstrate the relationship with SII and the mortality, major cardiovascular events, and success rates of percutaneous treatment of iliac artery disease. METHODS: A total of 600 patients underwent percutaneous intervention due to iliac artery disease were enrolled. The primary end point was mortality and the secondary end points were in-hospital thrombosis, restenosis, residual stenosis, and postintervention complications. The best cut-off value of SII to predict mortality was determined and the patients were divided into 2 groups, as those with higher SII values (1,073.782 <) and as those with lower SII values (1,073.782 >). Each group was evaluated in terms of clinical, laboratory, and technical aspects. RESULTS: After exclusion criteria were applied, 417 patients were enrolled into the study. Patients with high SII values had higher rates of in-hospital thrombosis [0 (0%); 3 (2.2%), P = 0.037] and mortality [38 (13.7%); 46 (33.1%), P < 0.001]. In multivariate logistic regression analysis, chronic kidney disease [odds ratio: 4.104, 95 0.5 confidence interval: 2.250-7.487, P < 0.001] and SII [odds ratio: 3.346, 95 0.5 confidence interval: 1.982-5.649, P < 0.001] were found to be independent risk factors for mortality. CONCLUSIONS: SII is a relatively new, simple, and effective mortality risk predictor in patients with iliac artery disease who underwent percutaneous intervention. To the best of our knowledge, our study is the first study which uses SII to predict mortality in such patient group.

RESUMO

OBJECTIVE: Critical limb ischemia (CLI) is a progressive form of peripheral artery disease (PAD). Patients with CLI have poor long-term prognosis. The aim of this study was to investigate the value of sarcopenia in terms of 1-year mortality in patients with below-the-knee lesions who underwent endovascular treatment for CLI. METHODS: A total of 190 patients with critical limb ischemia who underwent endovascular treatment (EVT) for below-the-knee (BTK) lesions were enrolled in this study. Sarcopenia was defined using the psoas muscle index (PMI). PMI was obtained by calculating the average psoas muscle area (APMA) of the left and right psoas muscles at the third lumbar vertebra level and dividing by the square of the height (cm2/m2). The primary endpoint of the study was 1-year mortality and the secondary endpoint was 1-year amputation. Patients were divided into 2 groups according to presence of sarcopenia. RESULTS: We detected sarcopenia in 64 patients. The mean age, height, and EF were higher in sarcopenia group. The psoas muscle area, weight, psoas muscle index, body-mass index, albumin level, and GFR were lower in sarcopenia group. The incidence of amputation (11.9% vs 29.7%, p = 0.003) and mortality (15.1% vs 35.9%, p = 0.001) were higher in patients with sarcopenia. Univariate and multivariate logistic regression analyses were used to determine the independent predictors of amputation and mortality. The survival curve for 1-year using the sarcopenia was analyzed using the Kaplan-Meier method, and statistical analysis was performed with the log-rank test. The presence of sarcopenia, glomerular filtration rate level, and low ejection fraction were found to be independent predictors of mortality. CONCLUSIONS: Sarcopenia was associated with 1-year mortality in patients with CLI undergoing EVT for BTK lesions. Also, patients with sacropenia had higher 1-year amputation rates. Sarcopenia may be a simple method to help patient selection, assessment, and intervention strategy for EVT and may improve patient outcomes.

RESUMO

OBJECT: Native T1 mapping provides tissue-specific T1 relaxation times, which can be used to identify structural changes in the various organs. The object of this article was to evaluate the bladder wall of patients with overactive bladder using native T1 mapping and compare the relaxation times of patients and healthy controls. MATERIAL AND METHODS: Seventeen patients with a diagnosis of overactive bladder and 15 healthy controls were enrolled in this prospective study. All participants underwent pelvic MRI and T1 maps were acquired. Native T1 relaxation times were calculated via regions of interest acquired from the anterosuperior wall of the bladder in all participants. Mean T1 relaxation times of the overactive bladder patients were compared with those of controls. RESULTS: Overactive bladder patients had statistically significantly higher T1 relaxation times compared with controls (p = 0.004). In the subgroup analysis, there was no statistically significant difference between males (1113.42 ± 62.4) and females (1176.70 ± 100.9) regarding the T1 relaxation times (p = 0.165). There were no correlations between age and T1 relaxation times in patient or control groups (r = 0.057, p = 0.825, and r = 0.052, p = 0.932, respectively). CONCLUSION: Native T1 mapping can identify structural changes in the bladder wall of patients with overactive bladder. This technique has a promising role in the diagnosis of patients with suspected overactive bladder.

RESUMO

INTRODUCTION: Steroid therapy is known to be effective against granulomatous mastitis. We aimed to compare the efficacy of local versus systemic steroid administration in patients with idiopathic granulomatous mastitis. MATERIALS AND METHODS: This prospective cohort study included 58 patients who had either local (n = 42) or systemic (n = 16) treatment due to granulomatous mastitis between 2015 and 2019. Recurrence rates were determined as per ultrasound and magnetic resonance imaging examinations and the rate of side effects was evaluated as per patient complaints and physical examinations at the end of a 2-year follow-up period. RESULTS: Median doses of 140 mg and 3810 mg were administered to the local and systemic group, respectively. Six (14.3%) patients in the local treatment group and 13 (81.3%) in the systemic treatment group had steroid-related side effects. The local treatment group had significantly fewer side effects than the systemic treatment group (P < 0.001). The recurrence rates were similar in both groups (P > 0.05). CONCLUSIONS: Local steroid injection was as effective as systemic steroid therapy. Compared to systemic therapy, local steroid administration can be considered as a new therapeutic protocol with a lower dose and side effect rate.

RESUMO

INTRODUCTION: We aimed to study the characteristics of peritoneal dialysis (PD) patients with coronavirus disease-19 (COVID-19), determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome. METHODS: In this multicenter national study, we included PD patients with confirmed COVID-19 from 27 centers. The baseline demographic, clinical, laboratory, and radiological data and outcomes at the end of the first month were recorded. RESULTS: We enrolled 142 COVID-19 patients (median age: 52 years). 58.2% of patients had mild disease at diagnosis. Lung involvement was detected in 60.8% of patients. Eighty-three (58.4%) patients were hospitalized, 31 (21.8%) patients were admitted to intensive care unit and 24 needed mechanical ventilation. Fifteen (10.5%) patients were switched to hemodialysis and hemodiafiltration was performed for four (2.8%) patients. Persisting pulmonary symptoms (n = 27), lower respiratory system infection (n = 12), rehospitalization for any reason (n = 24), malnutrition (n = 6), hypervolemia (n = 13), peritonitis (n = 7), ultrafiltration failure (n = 7), and in PD modality change (n = 8) were reported in survivors. Twenty-six patients (18.31%) died in the first month of diagnosis. The non-survivor group was older, comorbidities were more prevalent. Fever, dyspnea, cough, serious-vital disease at presentation, bilateral pulmonary involvement, and pleural effusion were more frequent among non-survivors. Age (OR: 1.102; 95% CI: 1.032-1.117; p: 0.004), moderate-severe clinical disease at presentation (OR: 26.825; 95% CI: 4.578-157.172; p < 0.001), and baseline CRP (OR: 1.008; 95% CI; 1,000-1.016; p: 0.040) were associated with first-month mortality in multivariate analysis. DISCUSSION/CONCLUSIONS: Early mortality rate and medical complications are quite high in PD patients with COVID-19. Age, clinical severity of COVID-19, and baseline CRP level are the independent parameters associated with mortality.

RESUMO

BACKGROUND: Chronic limb-threatening ischemia (CLTI), which presents with ischemic rest pain, ulceration, or gangrene, is a complex form of peripheral artery disease that can cause mortality and amputation. C-reactive protein (CRP), an inflammatory marker, indicates vascular inflammation resulting from the cytokine-dependent inflammatory process in the arterial wall, and arterial atherosclerosis resulting from the inflammation. Lower albumin levels are also associated with peripheral artery disease. We investigated the association between CRP/Albumin ratio (CAR) and long-term mortality in patients with CLTI. METHODS: A total of 172 patients who underwent endovascular treatment (EVT) for below the knee (BTK) lesions were enrolled in this study. Patients with acute infection requiring antibiotic therapy, chronic inflammatory disease, end-stage liver disease, malignancy were excluded from the study. Besides, patients with pre-follow-up intervention to the same vascular bed were also excluded from the study. The primary endpoint of the study was all-cause mortality. Patients were divided into 2 groups according to mortality. RESULTS: A total of 70 patients (40.6%) died during 32 ± 21 months of follow-up in the present study. The major amputation rate was 21.5%. The mortality (+) group was older and had higher rates of congestive heart failure, chronic kidney disease, history of stroke, and CRP levels. Moreover, statin and ACE inhibitor/angiotensin receptor blocker (ACE/ARB) use, GFR, and albumin levels were lower in the mortality (+) group. CAR was significantly higher in the mortality (+) group when comparing both groups (3.25 [1.46 - 7.86] vs. 9.75 [4.5 - 17.71], P < 0.001). CAR, congestive heart failure, chronic kidney disease, history of stroke, ACE/ARB, or statin use were independent predictors of all-cause mortality in multivariable Cox regression analysis. CONCLUSIONS: CAR was associated with mortality in CLTI patients undergoing EVT for BTK lesions. CAR may be a simple method to help patient selection, assessment, and intervention strategy for EVT and may improve patient outcomes.

RESUMO

BACKGROUND: In this study, we aimed to investigate the prognostic value of C-reactive protein (CRP) to albumin ratio (CAR) for predicting restenosis in superficial femoral artery (SFA) lesions and its association with subsequent clinical outcomes in patients undergoing endovascular intervention. METHODS: The records of 685 consecutive patients who underwent endovascular intervention due to symptomatic peripheral artery disease were analyzed. Patients were divided into 2 groups, based on the CAR values. For each group, technical aspects of procedures and subsequent clinical outcomes were analyzed. RESULTS: According to our study, patients with high CAR values had higher rates of restenosis (30.2% vs. 10.3%, P < 0.05) and mortality (31.3% vs. 12.9%, P < 0.05). The rate of lower extremity amputations was also significantly higher in patients with high CAR values compared to those with low CAR values (9.1% vs. 3%, P < 0.05). With respect to Receiver operating characteristic ROC curves of inflammatory markers, the area under the curve (AUC) value of CAR was statistically significant (AUC: 0.659; 95% confidence interval CI: 0.611-0.706; P < 0.01). CONCLUSIONS: Our data showed that CAR is an independent predictor of restenosis and poor clinical outcomes in patients undergoing endovascular intervention.

RESUMO

OBJECTIVE: Both fibroadenomas (FAs) and phyllodes tumors (PTs) are classified as fibroepithelial lesions. PTs are rare fibroepithelial neoplasms that have a morphologic spectrum ranging from benign to malignant. The differentiation of these entities is important as PTs are to be enucleated surgically. The purpose of this study was to calculate the T1 relaxation times of fibroadenomas and phyllodes tumors and assess the potency of native T1 mapping for the differentiation of these tumors. MATERIALS AND METHODS: This prospective study included 11 patients with a proven diagnosis of benign PT and 14 patients with a proven diagnosis of FA. All the patients underwent T1 mapping prior to conventional dynamic contrast-enhanced MRI (DCE-MRI). Two radiologists, in consensus, selected lesion locations using freehand regions of interest from the DCE images and copied them onto T1 maps to acquire T1 relaxation times. The T1 relaxation times of the FA and PT groups were compared statistically. RESULTS: The mean T1 relaxation times were higher in the PT group compared to the FA group (p ≤ 0.001). The receiver operating characteristic analysis showed that the T1 relaxation time being longer than 1,478 ms differentiated PTs from FAs with a sensitivity of 0.89, specificity of 1, and area under the curve value of 0.93. CONCLUSION: We found that benign PTs had longer relaxation times in T1 mapping compared to FAs. Native T1 mapping can be used to differentiate PTs from FAs and adding T1 mapping in breast MRI in cases with fast-growing fibroepithelial lesions or multiple fibroepithelial lesions can facilitate the decision-making process.

RESUMO

OBJECTIVES: Vascular calcification is a well-known phenomenon and affects coronary and carotid arteries as well as other arterial beds. Presence of arterial calcification is associated with major adverse events in patients undergoing percutaneous coronary artery or carotid artery intervention. Even though there is a clear association between worse outcome and coronary-carotid calcification, there is no research that interrogated the relationship between iliac arterial calcification and clinical outcomes because of lack of data. Therefore, in this study, we aimed to investigate the impact of iliac arterial calcification on procedure success rates and long-term outcomes among patients undergoing endovascular intervention. METHODS: The records of 453 consecutive patients who underwent endovascular intervention due to symptomatic peripheral artery disease were analyzed. Patients were divided into two groups based on the presence or absence of heavy calcification of iliac arteries. For each group, technical aspects of procedures and subsequent clinical outcomes were analyzed. RESULTS: According to our study, the rate of restenosis following endovascular intervention at 6 and 12 months were similar between two groups. On the other hand, long-term restenosis was significantly higher in patients with heavy calcification of iliac arteries as compared to patients with low calcification on iliac arteries (32.2% vs. 12.8%, p < 0.05). CONCLUSIONS: Our data showed that there was a strong association between heavy calcification of iliac arteries and long-term restenosis in patients undergoing endovascular intervention.

RESUMO

BACKGROUND: Carotid artery stenting is a minimally invasive, durable alternative treatment option, which is an alternative to the reference method, carotid endarterectomy, for patients with carotid artery stenosis; however, silent new ischemic cerebral lesions (SNICLs) after carotid artery stenting remain as a matter of concern. Hence, we aimed to assess the effect of complex vascular anatomy on silent new ischemic cerebral lesions in carotid artery stenting procedures. METHODS: We prospectively evaluated 122 patients (mean age: 69.5 ± 7.1 years, male:83) who underwent carotid artery stenting for carotid artery revascularization. The patients having symptomatic transient ischemic attack or stroke after carotid artery stenting were excluded. The presence of a new hyperintense lesions on diffusion-weighted imaging without any neurological findings was considered as the SNICL. Patients were classified into two groups as DWI-positive and DWI-negative patients. RESULTS: Among the study population, 32 patients (26.2%) had SNICLs. The DWI-positive group had a significantly higher common carotid artery (CCA)-internal carotid artery (ICA) angle, older age, more frequent history of stroke, a higher proportion of type III aortic arch, and longer fluoroscopy time than the DWI-negative group. High CCA-ICA angle was identified as one of the independent predictors of SNICL (OR (odds ratio) = 1.103 95%CI (confidence interval): (1.023-1.596); p = 0.034), and CCA-ICA angle higher than 34.5 degrees predicted SNICL with a sensitivity of 62.5% and a specificity of 62.2% (area under the curve: 0.680; 95% CI: 0.570 to 0.789; p = 0.003). CONCLUSIONS: The higher CCA-ICA angle may predict pre-procedure SNICL risk in carotid artery stenting and may have clinical value in the management of patients with carotid artery stenosis.

RESUMO

OBJECTIVES: Ultrasonography in a child with suspected appendicitis is primarily performed to detect inflamed appendix, whereas secondary findings are important in patients with a nonvisualized appendix. The aim of this study is to evaluate the gallbladder wall thickness and volume in patients with suspected appendicitis and search an association between these parameters and appendicitis. METHODS: Between January 2018 and August 2018, 113 patients with suspected appendicitis were included in this prospective study. Gallbladder and right lower quadrant were evaluated in separate sessions by different radiologists. The wall thickness along with the width, length, and height of the gallbladder was measured and recorded for each patient. Assessment of the appendix was classified as acute appendicitis, normal, and equivocal. Statistically significant association was sought between the thickness of the gallbladder wall and diagnosis of appendicitis. RESULTS: Gallbladder wall thickness was significantly higher in patients without appendicitis (P = 0.017), whereas significantly increased gallbladder volume was observed in patients with appendicitis (P = 0.004). Receiver operating characteristic analysis showed gallbladder wall thickness threshold of 0.5 mm with a sensitivity of 83.3, specificity of 93.9, and volume threshold of 41.6 mL with a sensitivity of 100 and a specificity of 0.69. CONCLUSIONS: Gallbladder wall thickness and volume measurements were associated with the diagnosis of appendicitis in pediatric patients.

RESUMO

BACKGROUND: Depression is the most common psychiatric problem in older individuals. In some countries, the common approach is to ignore psychiatric disorders. This study aimed to reveal the importance of newly diagnosed high depression scores in the geriatric population admitted to outpatient clinics with somatic complaints. METHODS: Patients who did not have a previous diagnosis of a psychiatric disorder and were not receiving treatment were included in the study. A comprehensive geriatric evaluation of 235 elderly patients was performed using established assessment tests. The time and quality of sleep and the Clinical Frailty Scores (CFSs) were documented. RESULTS: The mean age of the 235 patients was 73.6 ± 6.39 years, 65.5% (n = 154) were women, and 34.9% (n = 81) had a geriatric depression score ≥ 5. In the higher depression rating scores group, the Lawton-Brody, Mini-Mental State Examination (MMSE), and Mini Nutritional Assessment (MNA-SF) scores were low (p = 0.010, p < 0.001, p = 0.003). Sleep duration was short, and sleep quality was poor (p = 0.042, p = 0.006). The CFSs were high. (p = 0.035) According to the regression analysis results, the MMSE, MNA-SF and CFS predicted higher depression scores significantly (p = 0.048, ß = .892; p = 0.045, ß = .661; p = 0.045, ß = 1.245). DISCUSSION: Depression scores in older people may be associated with not only mood but also the functionality. As with other geriatric syndromes, symptoms in depression may be atypical rather than typical.

RESUMO

Medications show their biological effects by interaction with enzymes, which have been known to play an essential role in the pathogenesis of many diseases. Inhibition or induction of drug metabolizing enzymes has an essential place in the drug design for many kinds of diseases including cardiovascular, neurological, metabolic, and cancer. The main goal of the current study is to contribute to this growing drug design field by observing PON1-drug interactions. In recent years, the safety of gadolinium-based contrast agents (GBCAs) used in magnetic resonance imaging (MRI) has discussed. In the present study, paraoxonase 1 (PON1) enzyme was purified from human serum by simple chromatographic methods with 4095.24 EU mg-1 protein specific activity. The inhibitory activities of gadoteric acid, gadopentetic acid, gadoxetate disodium, and gadodiamide were investigated on PON1 activity of the enzyme. IC50 values were found in the range of 51.28 ± 0.14 to 285.80 ± 0.96 mM. Ki constants were found as 67.95 ± 0.60 mM, 104.97 ± 0.96 mM, 202.33 ± 1.75 mM, and 299.43 ± 2.64 mM for gadoteric acid, gadopentetic acid, gadoxetate disodium, and gadodiamide, respectively. While the inhibition types are determined as competitive of gadoxetate disodium and gadodiamide by the Lineweaver-Burk curves, it was noncompetitive for other compounds. In addition, the molecular docking analyses of gadoxetate disodium and gadodiamide were carried out to understand the binding interactions on the active site of the PON1 enzyme. The structure-activity relationship (SAR) of the drugs was established on the basis of different substituents and their positions in the compounds.

RESUMO

BACKGROUND: A curfew for elderly people was announced in Turkey to protect the geriatric population during the COVID-19 pandemic. Although this may have the beneficial effect of preventing infection, psychological distress may also increase with prolongation of the pandemic. METHODS: Geriatric patients were interviewed by telephone due to the ongoing curfew. Demographical characteristics, comorbidities, personal risk perception of COVID-19, common concerns related to COVID-19, and experiences of delayed hospital admission due to the pandemic were recorded. The Hospital Anxiety and Depression Scale (HADS) was used to assess psychological distress, anxiety, and depression. RESULTS: Participants (n = 136; 82 females, 60.3%) had a mean age of 73.4 ± 5.9 years. The most common comorbidity was hypertension (75%). Approximately 80% of the participants reported a decrease in physical activity during the curfew period. The HADS scores indicated rates of anxiety as 25.7% and depression as 16.9%. Anxiety was significantly more common in females than males (P = 0.002). Sleep problems (P = 0.000), fatigue (P = 0.000), and hopelessness (P = 0.000) were more common in participants with depression and anxiety. Logistic regression analyses showed an association between a delay in hospital admission and the presence of depression (P = 0.0029, R2  = 0.146). Personal risk perception of COVID-19 was statistically significantly higher among patients with anxiety (P = 0.0027, R2  = 0.157). CONCLUSION: Decreased adaptation to external and internal factors among older individuals may facilitate unfavourable outcomes of the pandemic. These results indicate that the geriatric population was mentally and physically affected by the restrictions and isolation.
