Comprehensive evaluation of older patients with suspected malignancy: 5-year experience of a tertiary geriatric inpatient unit.

OBJECTIVE: Geriatric cancer population is growing. Both cancer and geriatric conditions are associated with some degree of inflammatory burden. To comprehensively present our five years of experience in patients with suspicion of a malignancy, signs and symptoms that are more prominent as indicator of malignancies, conditions that cause malignancy-like symptoms, and common malignancies and newly diagnosed malignancies in geriatric patients with a history of cancer. METHODS: Patients hospitalized with suspected malignancy in a geriatric inpatient unit were included. Demographic data, hospitalization symptoms, clinical findings, smoking history, laboratory and further examinations, comprehensive geriatric assessment scores, length of hospital stay and discharge diagnoses were examined. Endoscopy and colonoscopy findings were also recorded. RESULTS: Of the 1,104 patients hospitalized for various reasons in the five-year period, 197 (106 women) were suspected of having a malignancy. Mean age was 78.22 ± 7.27. A total of 65 (33%) patients were diagnosed with a malignancy. Amount of smoking (pack/year) and geriatric depression scale (GDS) scores were significantly higher in malignant group (p = .009; p < .001; respectively). Of the hospitalization symptoms, frequency of lumbar-hip-back pain was significantly higher in the malignant group (p = .043). The three most common cancers were hematologic (32%), lung (15%), and gastrointestinal cancers (15%). Gastritis was the most common pathological finding from gastroscopies (58%), and adenoma from colonoscopies (24%). Malignancies were detected in 40% of patients with a history of malignancy, and 55% of the newly detected malignancies were new primaries. Immunoglobulin G4-related disease was one of the detected interested benign conditions. CONCLUSION: The frequency and presentation patterns of malignancies may differ in older adults. Depressive symptoms are common in geriatric cancer patients. Geriatric patients with a history of malignancy should be evaluated in detail for new primary malignancies.

Glutathione-related antioxidant defence, DNA damage, and DNA repair in patients suffering from post-COVID conditions.

Post-COVID conditions are defined as the continuation of the symptoms of Coronavirus Disease 2019 (COVID-19) 3 months after the initial Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, with no other explanation. Post-COVID conditions are seen among 30%-60% of patients with asymptomatic or mild forms of COVID-19. The underlying pathophysiological mechanisms of post-COVID conditions are not known. In SARS-CoV-2 infection, activation of the immune system leads to increased production of reactive oxygen molecules, depleted antioxidant reserve, and finally occurrence of oxidative stress. In oxidative stress conditions, DNA damage increases and DNA repair systems impair. In this study, glutathione (GSH) level, glutathione peroxidase (GPx) activity, 8-hydroxydeoxyguanosine (8-OHdG) level, basal, induced, and post-repair DNA damage were investigated in individuals suffering from post-COVID conditions. In the red blood cells, GSH levels and GPx activities were measured with a spectrophotometric assay and a commercial kit. Basal, in vitro H2O2 (hydrogen peroxide)-induced, and post-repair DNA damage (DNA damage after a repair incubation following H2O2-treatment, in vitro) were determined in lymphocytes by the comet assay. The urinary 8-OHdG levels were measured by using a commercial ELISA kit. No significant difference was found between the patient and control groups for GSH level, GPx activity, and basal and H2O2-induced DNA damage. Post-repair DNA damage was found to be higher in the patient group than those in the control group. Urinary 8-OHdG level was lower in the patient group compared to the control group. In the control group, GSH level and post-repair DNA damage were higher in the vaccinated individuals. In conclusion, oxidative stress formed due to the immune response against SARS-COV-2 may impair DNA repair mechanisms. Defective DNA repair may be an underlying pathological mechanism of post-COVID conditions.

The relationship between malnutrition and neutrophil-to-lymphocyte ratio in hospitalized older patient.

OBJECTIVES: Aging is characterized by appetite loss and cachexia, i.e., factors that contribute to malnutrition. An inflammation marker, neutrophil-to-lymphocyte ratio (NLR), is a significant prognostic predictor of many geriatric syndromes. We aim to determine the association between NLR and malnutrition. METHODS: We designed a retrospective study on hospitalized patients in the geriatric unit of a university hospital between January 2019 and January 2021. Demographic data, chronic diseases, history of smoking, length of hospital stay, number of drugs, laboratory and further examinations, and comprehensive geriatric assessment scores were recorded from the hospital data system. The nutritional status of the patients was evaluated using the mini-nutritional assessment (MNA) questionnaire. RESULTS: Of the 220 patients, 121 (55 %) were female, and the mean age was 77.9 ± 7.3 years. According to the MNA, 60 % (n = 132) were malnourished or at risk of malnutrition. As many as 47.3 % (n = 104) of the patients had depressive symptoms, and 41.4 % (n = 91) were cognitively impaired. The mean age (79.3 ± 7.3), NLR, and GDS scores were significantly higher, and MMSE scores were significantly lower in malnourished patients or in those at risk of malnutrition as compared to patients with normal nutritional status. We showed that NLR (OR: 1.248; 95% CI: 1.066‒1.461; p = 0.006), age (OR: 1.056; 95% CI: 1.005‒1.109; p = 0.031), depressive symptoms (OR: 1.225; 95% CI: 1.096‒1.369; p 4.5, with a sensitivity of 37.9 %, specificity of 85.2 %, negative predictive value of 47.8 %, and positive predictive value of 79.4 %. CONCLUSION: NLR, age, depressive symptoms, and cognitive impairment were independently associated risk factors for malnutrition. NLR may be a useful nutritional marker for evaluating the nutritional status of hospitalized geriatric patients (Tab. 4, Fig. 1, Ref. 28).

The impact of COVID-19 pandemic on the geriatric inpatient unit.

OBJECTIVE: We aimed to determine the effects of the pandemic on the inpatients in the geriatric unit by comparing the demographic and clinical characteristics, reasons for hospitalization, morbidity, and mortality of the patients before and during the pandemic. METHODS: The population of this retrospective, cross-sectional study consisted of inpatients in the geriatric unit for two years (11 March 2019-10 March 2021). The patients were separated into two groups according to the hospitalization time as pre-COVID-19 and COVID-19 period. Hospitalization types, reasons for hospitalization, length of stay, demographic data, chronic diseases, drugs, developed morbidities, discharge, and 1-year mortality status of the patients were recorded. RESULTS: Three hundred and fifty patients were included in our study. The mean age was 80.4 ± 8.02. It was observed that the number of hospitalized patients decreased by ∼50% in the COVID-19 period. However, there was a significant decrease in hospitalization due to the control of chronic diseases during the COVID-19 period (p = .008). The number of inpatients from the emergency department was found to be higher during the COVID-19 period (p < .001). Regarding the presence of geriatric syndromes, polypharmacy (p = .011) and delirium (p = .035) were found to be significantly less in the pre-COVID-19 period. The percentage of malnutrition was also detected as lower, but it was not statistically significant. In terms of 1-year mortality, although not statistically significant, the all-cause mortality rate was higher during the COVID-19 period (p = .08). CONCLUSIONS: Pandemic has greatly affected the geriatric unit. The prognosis of the patients has worsened and mortality rates have increased. Physiological and psychological deterioration caused by quarantine measures, worsening chronic diseases, and immunosenescence affected the prognosis of geriatric patients. This adds to the previous literature by proving the fact that older individuals are the most vulnerable group in the pandemic.

Fatigue and primary sarcopenia in geriatric patients

SUMMARY OBJECTIVE: This study aimed to investigate the frequency of fatigue in geriatric patients with primary sarcopenia and to evaluate the relationship between fatigue and symptoms such as depression and sleepiness. METHODS: This case-control study was conducted between December 2020 and August 2021 in the geriatrics outpatient clinic of Istanbul University-Cerrahpasa. The European Working Group on Sarcopenia in Older People 2 criteria were considered for the diagnosis of sarcopenia. Demographic data, accompanying chronic diseases, comprehensive geriatric assessments, and laboratory values of the patients were noted. Scales used to assess fatigue in all participants include Fatigue Assessment Scale, Fatigue Severity Scale, and Fatigue Impact Scale and associated symptoms include Geriatric Depression Scale and Epworth Sleepiness Scale. RESULTS: The mean (standard deviation) age was 75.3 (7.1) for 51 primary sarcopenia (38 female) patients and 73.5 (5.8) for 51 control (37 female) patients. There was no significant difference between the two groups in terms of gender and age (p=0.822, p=0.171). The prevalence of hypertension was higher, and the level of education was lower in the sarcopenic group than in the nonsarcopenic group (p=0.017, p=0.013). Fatigue Assessment Scale, Fatigue Severity Scale, Fatigue Impact Scale total, Fatigue Impact Scale cognitive, Fatigue Impact Scale physical, and Fatigue Impact Scale social questionnaire scores were significantly higher in the sarcopenic group (all p<0.001). The Geriatric Depression Scale score was statistically higher in the sarcopenic group; however, there was no significant difference in the Epworth Sleepiness Scale score between the two groups (p=0.014, p=0.072). Multivariate analysis was performed on education level, hypertension, fatigue questionnaires, and Geriatric Depression Scale, which were found to be significant in the univariate logistic regression analysis. In the multivariate logistic regression analysis, only the Fatigue Impact Scale total was determined to be associated with sarcopenia [odds ratio 1.161, 95% confidence interval (1.084-1.242)]. CONCLUSION: In primary sarcopenia, there is mental and social fatigue as well as physical fatigue. Therefore, the prevention and treatment of sarcopenia in geriatric patients is important.

Clinical outcomes of geriatric patients with COVID-19: review of one-year data.

AIMS: In this study, we aimed to reveal mortality rates and factors affecting survival in geriatric patients infected with COVID-19. METHODS: This is a retrospective study of 873 geriatric patients with COVID-19 who were hospitalized between March 11, 2020 and March 11, 2021. Demographic, clinical, laboratory data, and treatment options were obtained from electronic medical records. Multivariate logistic regression was used to explore the risk factors for in-hospital death. RESULTS: During the specified period, 643 patients were discharged, and 230 patients died in the hospital. The mean age was 75.08 ± 7.39 years (mean ± SD) and 51.8% were males. We found that older age (≥ 85), polypharmacy, dyspnea, abnormal thorax computed tomography (CT), lower doses of anticoagulation, and high values of white blood cell, aspartate aminotransferase, C-reactive protein, lactate dehydrogenase, ferritin were associated with a significant increase in mortality (P < 0.001 for all). Although all of these values were significant in multivariate logistic regression analysis, the most important ones were dyspnea (Odds ratio (OR) 57.916, 95% confidence interval (CI) 23.439-143.104, P < 0.001), polypharmacy (OR 6.782, 95% CI 3.082-14.927, P < 0.001), and thorax CT classification (typical; OR 9.633, 95% CI 2.511-37.122, P < 0.001). CONCLUSION: Older age, polypharmacy, dyspnea, and abnormal thorax CT were the most significant mortality criteria and in addition appropriate anticoagulant use was associated with reduced mortality. Identifying the risk factors to predict mortality in older adults with COVID-19 is important to treat future cases successfully.

Sarcopenia assessment by new EWGSOP2 criteria for predicting chemotherapy dose-limiting toxicity in patients with gastrointestinal tract tumors.

INTRODUCTION: In 2019, The EWGSOP2 group made updates on the definition and diagnosis of sarcopenia. The aim of this study is to determine the possible risk factors for chemotherapy dose-limiting toxicity (DLT). METHODS: Newly diagnosed gastrointestinal (GI) cancer patients were included in this prospective observational study. Chemotherapy DLTs were recorded in patients receiving platinum-based therapy. The patients were divided into two groups according to the current sarcopenia criteria. RESULTS: 75 patients were included in the final analysis. Chemotherapy DLT occurred in 52% (n = 39) of all patients who received platinum-based chemotherapy. DLT rates were 78.9% and 42.9% in sarcopenic and non-sarcopenic patients, respectively (p = 0.007). According to the results of the multivariate analysis, the only sarcopenia was found as a statistically significant risk factor for DLT. CONCLUSION: Assessment of sarcopenia evaluated with the current EWGSOP2 diagnostic criteria is useful in predicting chemotherapy DLT development in patients with a diagnosis of GI cancer. In the future, current EWGSOP2 recommendations should be considered while designing a study investigating the correlation between sarcopenia and chemotoxicity.

Determining host factors contributing to disease severity in a family cluster of 29 hospitalized SARS-CoV-2 patients: Could genetic factors be relevant in the clinical course of COVID-19?

In this study, we report a large family cluster consisting of 29 genetically related patients hospitalized with coronavirus disease-2019 (COVID-19). We sought to determine the clinical characteristics relevant to the clinical course of COVID-19 by comparing the family cluster to unrelated patients with SARS-CoV-2 infection so that the presence of potential determinants of disease severity, other than traditional risk factors previously reported, could be investigated. Twenty-nine patient files were investigated in group 1 and group 2 was created with 52 consecutive patients with COVID-19 having age and gender compatibility. The virus was detected for diagnosis. The clinical, laboratory and imaging features of all patients were retrospectively screened. Disease course was assessed using records regarding outcome from patient files retrospectively. Groups were compared with respect to baseline characteristics, disease severity on presentation, and disease course. There was no difference between the two groups in terms of comorbidity and smoking history. In terms of inhospital treatment, use differed not significantly between two groups. We found that all 29 patients in the group 1 had severe pneumonia, 18 patients had severe pneumonia. Hospitalization rates, length of hospital stay, and transferred to intensive care unit were found to be statistically significantly higher in the group 1. In the present study, COVID-19 cases in the large family cluster were shown to have more severe disease and worse clinical course compared with consecutive patients with COVID-19 presenting to the same time. We believe further studies into potential genetic mechanisms of host susceptibility to COVID-19 should include such family clusters.

Factors affecting mortality in geriatric patients hospitalized with COVID-19

Background/aim: We aimed to investigate the factors affecting the mortality of patients aged 65 years or older who were hospitalized with the diagnosis of new coronavirus pneumonia (COVID-19). Materials and methods: This is a retrospective study of patients 65 years old or older with COVID-19 who were hospitalized in Istanbul University-Cerrahpasa, Cerrahpasa Medical Faculty Hospital, between March 11 and May 28, 2020. Demographic, clinical, treatment, and laboratory data were extracted from electronic medical records. We used univariate and multivariate logistic regression methods to explore the risk factors for in-hospital death. Results: A total of 218 patients (112 men, 106 women) were included, of whom 166 were discharged and 52 died in hospital. With univariate analysis, various clinical features and laboratory variables were found to be significantly different (i.e. P < 0.05). In multivariate logistic regression analysis the following were independently associated with mortality: present malignancy [odds ratio (OR) = 4.817, 95% confidence interval (CI) = 1.107­20.958, P: 0.036]; dyspnea (OR = 4.652, 95% CI = 1.473­14.688, P: 0.009); neutrophil/lymphocyte ratio (NLR; OR = 1.097, 95% CI = 1.012­1.188, P: 0.025); the highest values of C-reactive protein (CRP; OR = 1.006, 95% CI = 1.000­1.012, P: 0.049), lactate dehydrogenase (LDH; OR = 1.002, 95% CI = 1.001­1.004, P: 0.003), and creatinine levels (OR = 1.497, 95% CI = 1.126­1.990, P: 0.006); oxygen saturation (SpO2) values on admission (OR = 0.897, 95% CI = 0.811­0.993, P: 0.036); and azithromycin use (OR = 0.239, 95% CI = 0.065­0.874, P: 0.031). Conclusion: The presence of malignancy; symptoms of dyspnea; high NLR; highest CRP, LDH, and creatinine levels; and low SpO2 on admission predicted mortality. On the other hand, azithromycin use was found to be protective against mortality. Knowing the causes predicting mortality will be important to treat future cases more successfully.

Tocilizumab challenge: A series of cytokine storm therapy experiences in hospitalized COVID-19 pneumonia patients.

To recognize the period of exaggerated cytokine response in patients with coronavirus disease 2019 (COVID-19) pneumonia, and to describe the clinical outcomes of using tocilizumab as a treatment option. The data of 12 adult COVID-19 pneumonia patients who were followed in the inpatient clinics of Biruni University Medical Faculty Hospital (Istanbul, Turkey) were retrospectively analyzed. Diagnostic tests, laboratory examinations, clinical findings, and computed tomography of the thorax imaging results were evaluated. A dramatic laboratory and clinical improvement was observed in 83% (10 out of 12) of patients after tocilizumab. In 17% (2 out of 12) of our patients, short-term ventilator support was required in the intensive care unit. The longest hospital stay was 18 days. However, in the end, all of our patients were discharged home with good health. Although arterial oxygen saturations (87.58 ± 3.12%) dropped in room air in the pre-tocilizumab period, post-tocilizumab they normalized in all patients (94.42 ± 1%). None of them had fever after tocilizumab treatment and the levels of C-reactive protein (13.08 ± 12.89) were almost within normal limits. Eosinophil values were quite low at the time of diagnosis (10 ± 17.06), but increased significantly post-tocilizumab (155.33 ± 192.69). There is currently no proven treatment for COVID-19 induced by novel coronavirus SARS-CoV-2. Based on our experience with twelve adult COVID-19 pneumonia patients, we can say that tocilizumab, an IL-6 inhibitor, is more beneficial in preventing the damage caused by excessive cytokine response in the body if administered at the right time and provides clinical and radiological recovery.

Myeloid-related protein complex 8/14 increases in hypertensive patients with excessive renal damage
.

AIM: Hypertension is a complex condition, and it is difficult to know whether inflammation is a cause or an effect. Information on the association between MRP-8/14 (myeloid-related protein) and hypertension is limited. In this study, we aimed to examine the relationship of MRP-8/14 with carotid intima-media thickness (CIMT) and albuminuria in hypertensive patients and to investigate whether early assay of MRP-8/14 levels could be helpful in assessment of renal damage and carotid atherosclerosis among hypertensive patients. MATERIALS AND METHODS: 61 hypertensive patients and 40 age-, gender-, and body mass index-matched controls were included into the study. Blood samples including fasting blood glucose, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total protein, albumin, urea creatinine, uric acid, sedimentation, C-reactive protein (CRP), and MRP-8/14 were collected. 24-hour urine albumin excretion and CIMT measurements were also obtained. RESULTS: All inflammatory variables including uric acid, CRP, sedimentation, MRP-8/14, and CIMT were statistically higher in patients with hypertension than in controls. MRP-8/14 was significantly higher in hypertensive patients with macroalbuminuria than in controls (339.3 (IQR (215.2 - 661.7)) ng/mL vs. 204.9 (IQR (140.1 - 339.3)) -ng/mL, p = 0.005, respectively). The levels of CIMT were the highest in macroalbuminuric hypertensive patients (controls vs. normoalbuminuria, microalbuminuria, macroalbuminuria groups, 0.57 (0.53 - 0.67) mm vs. 0.84 (0.76 - 0.89) mm, p = 0.000; 0.57 (0.53 - 0.67) mm vs. 0.87 (0.67 - 0.93) mm, p = 0.000; 0.57 (0.53 - 0.67) mm vs. 0.92 (0.85 - 0.97) mm, p = 0.000, respectively). CONCLUSION: Plasma MRP-8/14 levels were elevated in hypertensive patients with macroalbuminuria, however, it could not serve as an early marker to determine renal damage and carotid atherosclerosis in patients with hypertension.

The role of TMPRSS6 gene variants in iron-related hematological parameters in Turkish patients with iron deficiency anemia.

TMPRSS6 gene mutations can result in iron deficiency anemia (IDA) and cause an increased iron-regulatory hormone, hepcidin, levels. TMPRSS6 encodes a serine protease, matriptase-2, which functions as negative regulatory protein of hepcidin transcription. Thus, TMPRSS6 variations might be risk factors for IDA. The aim of the study was to investigate the association of rs855791, rs4820268, rs5756506, rs2235324, rs2413450, rs2111833, rs228919, and rs733655 SNPs in TMPRSS6 gene with IDA susceptibility and iron-related clinical parameters. The study consisted of 150 IDA patients and 100 healthy controls. We analyzed the genotype distributions by using Real-Time polymerase chain reaction (Real-Time PCR) technique. We did not find any statistically differences for all SNPs between patients and controls (P > 0.05). In IDA patients, variations rs855791 and rs2413450 were associated with increased RBC (P = 0.03) and TIBC (P = 0.04), respectively. Also, increased of TIBC for rs4820268 (P < 0.05). On the other hand, in control group, rs5756506 was associated with two parameters, Hb (P = 0.02) and Hct (P = 0.03). We did not find markedly hepcidin levels in IDA patients compared to controls (P = 0.32). Our findings suggest that TMPRSS6 variations may not be risk factors for IDA. However, TMPRSS6 polymorphisms are associated with increased many iron-related hematological parameters.

DNA damage, DNA susceptibility to oxidation and glutathione redox status in patients with Alzheimer's disease treated with and without memantine.

The aim of the current study was to compare oxidative DNA damage, DNA susceptibility to oxidation, and ratio of GSH/GSSG in patients with Alzheimer's disease (AD) treated with acetylcholinesterase inhibitor (AChEI) and combined AChEI+memantine. The study included 67 patients with AD and 42 volunteers as control. DNA damage parameters (strand breaks, oxidized purines, H2O2-induced DNA damage) in lymphocyte DNA and GSH/GSSG ratio in erythrocytes were determined by the comet assay and spectrophotometric assay, respectively. DNA damage was found to be higher, GSH/GSSG ratio was found to be lower in the AD group than those in the control group. DNA strand breaks and H2O2-induced DNA damage were lower in the patients taking AChEI+memantine than those in the patients taking AChEI but no significant difference was determined between the groups for oxidized purines and GSH/GSSG ratio. In conclusion, increased systemic oxidative DNA damage and DNA susceptibility to oxidation may be resulted from diminished GSH/GSSG ratio in AD patients. Although DNA strand breaks and H2O2-induced DNA damage are lower in the AD patients treated with combined AChEI and memantine, this may not indicate protective effect of memantine against DNA oxidation due to similar levels of oxidized purines in the patients treated with AChEI and AChEI+memantine.

Prevalence of fecal incontinence and associated risk factors in elderly outpatients: a cross-sectional study.

BACKGROUND: Data on the prevalence of fecal incontinence in elderly patients admitted to outpatient clinics in Turkey are scarce. AIMS: The aim of this study was to assess the prevalence of fecal incontinence and the associated risk factors in the elderly outpatients. METHODS: Patients 60 years and older admitted to a geriatrics outpatient clinic between October 2013 and March 2014 were included. Demographic characteristics, anthropometric measurements, marital status, educational status, parity (for females), fecal incontinence (FI), urinary incontinence (UI), constipation, comorbid conditions, and medications were recorded. FI assessment was based on the Fecal Incontinence Severity Index (FISI). RESULTS: A total of 364 patients (64.8% female, n = 236) with a mean age of 73.2 ± 8.1 years were enrolled in the study. The prevalence of FI was 9.9% (10.2% female, 9.4% male). UI was 42.6%. Co-occurrence of FI and UI was 7.4%. According to the FISI, the most frequent type of defecation was liquid stool (61.1%). While the predictive factors for FI were polypharmacy (standardized coefficient, [r] = 0.203, 95% confidence interval [CI] = 0.009-0.040, p = 0.002), UI (r = 0.134, 95% CI = 0.006-0.156, p = 0.035), and being married (r = 0.200, 95% CI = -0.088 to -0.020, p = 0.002) in females, those were UI (r = 0.306, 95% CI = 0.093-0.309, p < 0.001) and polypharmacy (r = 0.251, 95% CI = 0.009-0.043, p = 0.003) in males. CONCLUSIONS: In both genders, urinary incontinence and polypharmacy seem to be the most important risk factors for fecal incontinence. Fecal incontinence should be questioned in detail and evaluated using FISI in elderly outpatients.
