Evaluation of malnutrition with blood ghrelin and fecal elastase levels in acute decompensated heart failure patients.

OBJECTIVES: Exocrine pancreatic dysfunction may contribute to malnutrition and lack of appetite in the advanced stages of heart failure. Nutritional assessment was carried out on patients diagnosed with mild or moderate/severe heart failure. Fecal elastase levels are an indicator of pancreatic exocrine function and ghrelin is an appetite hormone which is also investigated for its contribution to malnutrition. STUDY DESIGN: This is an observational study. 52 patients (32 males, 20 females) aged over eighteen years and hospitalized for acute decompensated heart failure (ADHF) were included in the study. They were compared with 31 people (16 male, 15 female) of the same age as Control Group (C). Patients in New York Heart Association (NYHA) stages 1 and 2 were grouped as mild (miADHF), while those in NYHA stages 3 and 4 were grouped as moderate/severe ADHF (seADHF). Fecal and blood samples were taken at admission. In ADHF patients, exocrine pancreatic functions and their relationship with malnutrition were evaluated. Statistical analyses were performed using Tukey's test, the independent-sample t-test, the Kruskal-Wallis test, the Mann-Whitney U-test, the chi-square test and Pearson's bivariate correlation analysis. RESULTS: Significantly decreased fecal elastase levels were found when moderate/severe ADHF patients and the control group were compared. (C 278.9±144.8, miADHF 336.6±181.7, seADHF 168.7±153.6, p=0.002). 10 seADHF patients (50%) had severe, 4 (20%) moderate, and 6 (30%) mild pancreatic insufficiency. Ghrelin levels were higher in seADHF patients compared to C and miADHF patients (C 69.7±34.6, miCHF 82.5±48.2, SeADHF 105.0±78.1 p=0.361). CONCLUSION: Fecal elastase and ghrelin hormone levels can contribute to the determination of malnutrition in ADHF patients.

Assessment of inflammatory parameters as predictive markers for malignancy in thyroid nodules: a study on the correlation with Bethesda classification.

OBJECTIVE: The study aimed to assess the predictive significance of inflammatory parameters as potential markers for malignancy in individuals with thyroid nodules. METHOD: Nine hundred and ninety-one patients with thyroid nodules who had undergone thyroid fine-needle aspiration biopsy were included and classified according to the Bethesda system. Neutrophil lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) values obtained from hemogram parameters were determined for each patient. The study examined the correlation between the Bethesda classification and NLR/SII levels. In addition, a comparison was made between the inflammatory parameters of the benign and malignant Bethesda groups. RESULTS: Five hundred and seventy-three patients were classified as Bethesda 2 (benign), 34 as Bethesda 6 (malignant). A correlation was observed between the Bethesda classification and NLR and SII levels (r: 0.230, p < 0.001; r: 0.207 p < 0.001, respectively). NLR and SII values were significantly higher in the malignant group (p < 0.001). The cutoff value for SII in predicting benign and malignant thyroid nodules was 489.86 × 103/mm3 with a sensitivity of 88.2% and a specificity of 63.7%. The cutoff value for NLR for the same prediction was 2.06 with a sensitivity of 82.4% and a specificity of 83.4%. CONCLUSIONS: The findings of this study indicate that SII and NLR may be valuable prognostic markers for predicting the malignancy of thyroid nodules.

OBJETIVO: Evaluar parámetros inflamatorios como posibles marcadores de malignidad en individuos con nódulos tiroideos. MÉTODO: Se incluyeron 991 pacientes con nódulos tiroideos que se sometieron a biopsia por aspiración con aguja fina y se clasificaron según el sistema de Bethesda. Se determinaron los valores de la relación neutrófilo-linfocito (NLR) y el índice de inflamación inmunitaria sistémica (SII). El estudio exploró la correlación entre la clasificación de Bethesda y los valores de NLR/SII, y comparó los parámetros inflamatorios de los grupos benignos y malignos de Bethesda. RESULTADOS: Se clasificaron 573 pacientes como Bethesda 2 (benigno) y 34 como Bethesda 6 (maligno). Se observó una correlación entre la clasificación de Bethesda y los valores de NLR y SII (r: 0.230; r: 0.207). Los valores de NLR y SII fueron mayores en el grupo maligno (p < 0.001). El valor de corte para SII en la predicción de nódulos tiroideos benignos y malignos fue de 489.86 × 103/mm3, con una sensibilidad del 88.2% y una especificidad del 63.7%; para NLR fue de 2.06, con una sensibilidad del 82.4% y una especificidad del 83.4%. CONCLUSIONES: El SII y el NLR pueden ser valiosos marcadores pronósticos para predecir la malignidad de los nódulos tiroideos.

Effects of sodium-glucose cotransporter-2 inhibitors on nutritional status in heart failure with reduced ejection fraction.

OBJECTIVE: This study aimed to evaluate the effects of sodium-glucose cotransporter-2 inhibitors on nutritional status in patients with heart failure with reduced ejection fraction. METHODS: The sodium-glucose cotransporter-2 inhibitor treatment was initiated in 153 patients with heart failure with reduced ejection fraction who were symptomatic despite optimal medical treatment and were followed up for 6 months. The Minnesota Living With Heart Failure Questionnaire scores, New York Heart Association functional class, NT-pro-BNP levels, and nutritional index scores of the patients were evaluated before sodium-glucose cotransporter-2 inhibitor treatment and at the 6-month follow-up. The nutritional status of the patients was evaluated with the COntrolling NUTritional Status score, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index. RESULTS: After sodium-glucose cotransporter-2 inhibitor treatment, significant changes were observed in the mean scores of the three different nutritional indexes: COntrolling NUTritional Status (before: 2.76±2.43 vs. after: 1.12±1.23, p<0.001), Geriatric Nutritional Risk Index (before: 98.2±9.63 vs. after: 104.4±5.83, p<0.001), and Prognostic Nutritional Index (before: 37.9±4.63 vs. after: 42.9±3.83, p<0.001) scores. A significant decrease in the number of patients with malnutrition was observed according to the COntrolling NUTritional Status (before: 46.4% vs. after: 9.7%, p<0.001), Geriatric Nutritional Risk Index (before: 41.8% vs. after: 18.9%, p=0.006), and Prognostic Nutritional Index (before: 36.6% vs. after: 13.7%, p=0.007) scores. A significant functional improvement was observed in patients after sodium-glucose cotransporter-2 treatment: Minnesota Living With Heart Failure Questionnaire scores (before: 39.2±7.2 vs. after: 20.4±7.4, p<0.001), NT-pro-BNP levels (before: 2989±681 vs. after: 1236±760, p<0.001), and New York Heart Association class (before: class II-III: 95.5%; class IV: 4.5% vs. after: class II-III: 78%; class IV: 0%, p<0.001). CONCLUSION: In patients with heart failure with reduced ejection fraction who are symptomatic despite optimal medical treatment, the addition of an sodium-glucose cotransporter-2 inhibitor to treatment can significantly improve both the nutritional and functional statuses.

Assessment and outcome of hospitalized patients during delta variant COVID-19 pandemic: A multicenter international study.

INTRODUCTION: To date, the world has experienced four waves of the Coronavirus disease- 19 (COVID-19) pandemic. Patients infected during the era of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant were the subject of this study. The objectives were to describe their clinical manifestations, explain their laboratory and radiological findings, conclude factors contributing to clinical outcomes, and evaluate treatment protocols. METHODOLOGY: Relevant data were collected retrospectively from records of patients admitted to six referral centers in four countries. Data included sociodemographic patterns, symptoms, associated comorbidities, physical examination, laboratory and radiologic findings, treatment received, and patient outcomes. RESULTS: Data analysis identified symptomatology and variables related to acquisition and infection outcome. The most prevalent symptoms were cough (81.5%), body aches (74.1%), and fever (71.6%). Independent risk factors for mortality were age, vomiting, epigastric pain, diabetes, obesity, oxygen saturation less than 90%, leukocytosis, neutrophilia, lymphopenia, thrombocytopenia, elevated creatinine, high glucose level, lung ground glass opacities with consolidation, affection of four lobes and bilateralism. Neither d-dimer nor lactate dehydrogenase nor ferritin foretells death possibility. The efficacy of the medications used was convenient. CONCLUSIONS: Assessing the clinical features of different COVID-19 waves, identifying predictors of outcomes, and concluding the efficacy of treatment protocols provide insight into patients' responses and viral behaviors, which help in the proper diagnosis and treatment of subsequent surges.

RT- PCR testing of upper respiratory tract samples for diagnosis of SARS-CoV-2: Between justification and overestimation, a multi-center international study.

BACKGROUND: It has been found that patients recovered from COVID 19 may still test Reverse Transcriptase- Polymerase Chain Reaction (RT- PCR) positive without being infectious; the reasons are unclear. The occurrence of false-negative results of RT- PCR interferes with a proper diagnosis. The objectives of that work were to determine factors associated with persistently detectable SARS-CoV-2 RNA among recovered hospitalized patients and to determine the incidence of false-negative RT-PCR results and associated factors. METHODS: Relevant data were collected from 482 COVID 19 patients hospitalized in six referral centers from four countries. RESULTS: The median duration of RT- PCR conversion to negative was 20 days. Out of 482 studied patients, 8.7% tested positive after more than four weeks and were considered prolonged convertors. Binary logistic regression analysis revealed headache as an independent risk factor for short conversion time while fever, hypertension, chronic obstructive pulmonary disease, lymphopenia, elevated erythrocyte sedimentation rate, and the number of lobes affected, and bilateralism were found to be independent risk factors for prolonged positivity. Eighteen patients had initial negative results then turned positive after 24-48 h. Associated factors and outcomes were identified. CONCLUSION: Identifying patients with a high likelihood of COVID-19 despite a negative RT-PCR is critical for effective clinical care. However, patient isolation resumption depending on positive RT-PCR despite clinical and radiological recovery is an overrating that greatly burdens the health sector.

Investigating the correlation of the number of diagnostic criteria to serum adiponectin, leptin, resistin, TNF-alpha, EGFR levels and abdominal adipose tissue.

AIM: Cardiovascular diseases are among the leading causes of morbidity and mortality in developed countries. Metabolic syndrome is a common clinical presentation posing significant risk in cardiovascular diseases. This study investigated the correlation between the number of diagnostic criteria and serum adiponectin, leptin, resistin, TNF-alpha, EGFR levels and abdominal adipose tissue in the individuals with metabolic syndrome. MATERIALS AND METHODS: This study included a total of 40 patients (18 men and 22 women) with metabolic syndrome that applied to the Internal Diseases Outpatient Clinic of Ümraniye Training and Research Hospital between March 2011 and August 2011. The data including age, gender, personal history, familial history, habits, height, weight, systolic blood pressure, diastolic blood pressure, body mass index, waist circumference, hip circumference, body composition (tanita) were recorded for each patient. Blood samples were collected for biochemical examinations. The serum adiponectin, leptin, resistin, TNF-alpha, EGFR levels were measured. Statistical analyses were carried out using the NCSS (Number Cruncher Statistical System) 2007 and the PASS (Power Analysis and Sample Size) 2008 Statistical Software (UT, USA). RESULTS: When the patients with metabolic syndrome were analyzed by gender, no statistically significant difference was found between the EGFR and TNF-alpha levels (p>0.05). On the other side, the visceral fat rating and GGT levels of women were significantly lower than those of men (p<0.05). However, the resistin and leptin levels were found significantly higher in female patients as compared to male patients (p<0.05). CONCLUSION: In the present study, we did not observe any statistically significant change in abdominal adipose tissue thickness, serum TNF-alpha, adiponectin, resistin, and EGFR levels of the patients according to the number of diagnostic criteria; however, there was significant change in the patients' leptin levels.
