Characteristics and Gender-Related Differences of Patients Admitted to a Large Intensive Cardiac Care Unit: A Single-Center Experience with over 55 000 Patients.

OBJECTIVE: Parallel to the aging of the world population, the complexity of patients with cardiac problems has increased, especially in intensive cardiology care units, and the importance of multidisciplinary care has become more evident. The aim of this study was to analyze the clinical characteristics and gender-related differences of patients hospitalized in a large intensive cardiology care unit. METHODS: This single-center, retrospective, cross-sectional study includes all hospitalizations in a large intensive cardiology care unit between January 2016 and March 2021. All data were obtained using data collection software and transferred to MEDULLA, Turkey's general database system. RESULTS: Of the 55 737 consecutive patients included in the analysis, 16342 (29%) were women. The mean age of males was 59.71 ± 12 years, and the mean age of females was 63.3 ± 14 years (P <.001). Over a period of 5 years, the most common reason for hospitalization in the intensive cardiac care unit was acute coronary syndrome. The number of acute coronary syndrome patients who underwent coronary angiography was found to be 17 478 (31%), of which 12 878 were males and 26.3% were female. The number of patients who underwent at least 1 stent implantation was 13 952 (80% of coronary angiography procedures), and 2960 (21%) were women. The second cause of hospitalization in the intensive cardiology care unit was arrhythmias (5654 patients [10%]) followed by advanced heart failure (932 patients [1.7%]). During follow-up in the intensive cardiology care unit, the percentage of development of multiorgan failure was found to be approximately 18%. The mortality rate was 7% in women, which was higher than in men (4%). While the most common cause of death was acute coronary syndrome, the highest rate of death was found in patients with advanced heart failure. Among the patients who died, the mean age of females was higher than that of males, and the length of hospital stay was longer. CONCLUSION: Although numerically the highest death rate was observed in male acute coronary syndrome patients, the highest mortality rate was found in patients with advanced heart failure. Due to the elderly population and the increase in the number of patients requiring multidisciplinary treatment, the development of multiorgan failure in intensive cardiology care units seems to be one of the most important causes of death. Although the number of females hospitalized in the intensive cardiology care unit is lower than that of males, the mean age and mortality rate were found to be higher than males.

Predictive value of post-procedural hyponatremia on contrast-induced nephropathy in patients who underwent coronary angiography or percutaneous coronary intervention.

OBJECTIVE: Hyponatremia is a prognostic marker for specific pathologies. However, the association between contrast-induced nephropathy (CIN) and post-procedural hyponatremia has not been explored. Our study aims to evaluate the association between hyponatremia developing after contrast media administration and CIN. MATERIAL AND METHODS: A total number of 236 patients who required nephrology consultation before coronary angiography (CAG) or percutaneous coronary intervention (PCI) because of the high risk for contrast nephropathy, were included. Serum sodium levels were measured at admission and within three consecutive days after contrast media administration. RESULTS: Hyponatremia was observed in 141patients (59.7%) following angiography. CIN was developed in 149 (63.4%) patients. Among the patients who developed hyponatremia, ejection fraction, serum haemoglobin level and serum albumin level were low whereas, contrast media volume and percentage of the diabetes mellitus were higher. Also, length of hospital stay, percentage of CIN, renal replacement requirement and mortality rate were higher in patients with hyponatremia. In univariable analysis to evaluate the risk factors for CIN, being female gender, age, diabetes mellitus, serum albumin concentration, haemoglobin level, contrast media volume and hyponatremia were associated with development of CIN. Multivariable logistic regression analysis revealed that advanced age, serum albumin concentration and hyponatremia were independent predictors of CIN. CONCLUSION: Post-procedural hyponatremia was an independent risk factor for CIN in CAG or PCI patients.

Relationship Between Serum Magnesium Level and Insulin Resistance in Turkey Non-obese Adult Population.

The homeostasis model assessment of insulin resistance (HOMA-IR) is widely used in clinical practice to estimate insulin resistance. In particular, magnesium (Mg) is an extensively studied mineral that has been shown to function in the management of hyperglycemia and insulin resistance (IR) action. The pathophysiology of IR in non-obese patients has not been clearly demonstrated. From this point of view, we aimed to investigate the relationship between serum Mg level and IR in non-obese patients. We analyzed 957 patients who are not obese and estimated glomerular filtration rate (e-GFR) ≥ 60 mL/min/1.73 m2. Patients were divided into two groups, with and without IR. The results of the IR detected group (HOMA-IR ≥ 2.5, n = 544) and the IR undetected group (HOMA-IR < 2.5, n = 413) were compared. The median Mg value of the patients was 1.76 [0.21] mg/dL. A statistically significant difference was observed between the two groups regarding serum Mg levels (p = 0.043). A negative correlation was found between the HOMA-IR index and serum Mg levels among patients (r = - 0.064, p = 0.049). Multivariable logistic regression analysis revealed that serum Mg level (p = 0.039, odds ratio [OR] = 0.770[95%CI: [0.917-0.989]) was independent risk factors for IR. HOMA-IR increases as the Mg level decreases in advanced ages without obesity, especially in men with low e-GFR.

Uric acid albumin ratio as a predictive marker of short-term mortality in patients with acute kidney injury.

OBJECTIVE: We aimed to investigate uric acid and albumin ratio (UA/A) as a marker of short-term mortality in acute kidney injury (AKI). Both uric acid and albumin are strongly correlated with the development and mortality of AKI. METHODS: The patients hospitalized from May 2019 to September 2019 for AKI were included in this study. The diagnostic odds ratio (DOR), Youden index (J), and the area under a receiver operating characteristic curve (AUROC) determined a cut-off UA/A ratio for mortality. Cox-regression analysis was performed to identify UA/A as a prognostic marker of the 30-day mortality rate. RESULTS: A total of 171 patients with an average age of 69.20±13.0 (45.6% women) were included in the study. The average UA/A ratio was 3.3±1.5 mg/g and 2.5±1.0 mg/g in the non-survivor and survivor groups, respectively (P=0.001). The best cut-off UA/A ratio associated with mortality was determined as 2.4 mg/g with a specificity of 52% and a sensitivity of 77% (DOR, 3.6; J, 28.8; AUROC, 0.644). Thirty-day cumulative survival rates of the low and high UA/A ratio groups were 85.9±4.0% and 63.7±5.0%, respectively. The estimated survival times of the low and high UA/A ratio groups were 27.7 days (95% confidence interval [CI], 26.2-29.3) and 23.9 days (95% Cl, 22.0-25.9), respectively. CONCLUSION: We found a direct correlation between 30-day mortality and UA/A ratio at initial presentation in AKI patients regardless of age, comorbidities, and clinical and laboratory findings, including albuminuria.

Presence of ear lobe crease may predict intermediate and high-risk patients with acute non-ST elevation acute coronary syndrome.

Introduction: Ear lobe crease (ELC) was first described in 1973 as a physical examination finding indicating significant coronary artery disease (CAD). Several studies have been carried out in relation to this finding, and it has been shown that it is a marker of intima-media thickness, carotid artery disease, and CAD. We aimed to investigate the relationship between earlobe crease, which is a simple physical examination finding, and GRACE score as a risk estimation index in acute coronary syndromes without ST-segment elevation (NSTE-ACS) patients. Methods: 360 patients (mean age 62.2 years, 70% male) were included in our study. Patients were divided into two groups of GRACE scores ≤ 109 and >109, 167 patients were enrolled in group 1, and193 cases in group 2. Results: The group 2 patients were older, had higher systolic blood pressure (SBP) levels, a higher rate of hypertension, higher glucose levels, lower creatinine clearance levels, higher initial and peak troponin levels, lower hemoglobin levels, lower left ventricular ejection fraction (LVEF) and higher Gensini scores than the patients in group 1. The higher GRACE score group had markedly increased frequencies of ELC compared to the lower GRACE score group (80.8% vs. 24.5%, respectively, P < 0.001). Conclusion: The presence of ELC may predict moderate to high risk group of patients with NSTEACS.

The mid-term effect of left ventricular assist devices on renal functions.

BACKGROUND: In this study, we aimed to investigate the mid-term effects of left ventricular assist devices on kidney functions. METHODS: Between January 2015 and December 2017, a total of 61 patients (53 males, 8 females; mean age 46.4±11.2 years; range, 20 to 67 years) who underwent left ventricular assist device implantation were retrospectively analyzed. Glomerular filtration rate was evaluated preoperatively and at 24 and 48 h, at one week, and at one, three, and six months postoperatively. According to the preoperative glomerular filtration rates, the patients were divided into three groups: glomerular filtration rates ?60 mL/min/1.73 m2 ( Group 1 ), g lomerular f iltration rates 61-90 mL/min/1.73 m2 (Group 2), and glomerular filtration rates >90 mL/min/1.73 m2 (Group 3). RESULTS: In all groups, the glomerular filtration rate significantly increased at one week and one month postoperatively, compared to preoperative values (p<0.001 and p<0.01, respectively). However, the glomerular filtration values at six months significantly decreased, compared to the values at one week and one month postoperatively (p<0.001 and p<0.001, respectively). The most significant drop to preoperative values was observed in Group 3 (p=0.02) at three months and it dropped below the preoperative level at six months (p<0.001). CONCLUSION: Our study results suggest that left ventricular assist devices can significantly increase the glomerular filtration rate in short-term, irrespective of baseline values. However, this improvement may recede later, particularly in patients with normal renal functions, and it may even disappear following the third postoperative month.

MCP-1 and soluble TWEAK levels are independently associated with coronary artery disease severity in patients with chronic kidney disease.

PURPOSE: Patients diagnosed with chronic kidney disease (CKD) have a greater rate of cardiovascular mortality when compared with the general population. The soluble form of TNF-like weak inducer of apoptosis (TWEAK) and monocyte chemoattractan protein 1 (MCP-1) play important roles in cellular proliferation, migration and apoptosis. The current study aimed to analyze whether soluble TWEAK (sTWEAK) and MCP-1 levels are associated with the severity of coronary arterial disease (CAD) in CKD patients. METHODS: Ninety-seven patients diagnosed with CKD stages 2-3 according to their estimated glomerular filtration rate and the presence of kidney injury were included in the study. Plasma sTWEAK and MCP-1 concentrations were determined using commercially available ELISA kits. Coronary angiographies were performed through femoral artery access using the Judkins technique. RESULTS: Correlation analysis of sTWEAK and Gensini scores showed significant association (p < 0.01, r(2) = 0.287). Also significant correlation has been found in MCP-1 levels and Gensini scores (p < 0.01, r(2) = 0.414). When patients were divided into two groups with a limit of 17 according to their Gensini score, sTWEAK levels indicated a statistically significant difference (p < 0.01). CONCLUSIONS: Our findings support a relationship between sTWEAK and MCP-1 levels and CAD in CKD stages 2-3 patients.

A Rare Reason of Ileus in Renal Transplant Patients With Peritoneal Dialysis History: Encapsulated Peritoneal Sclerosis.

Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

Proteinuria associated with mTOR inhibitors after kidney transplant.

OBJECTIVES: The mammalian target of rapamycin inhibitors sirolimus and everolimus are immunosuppressive drugs for kidney transplant patients, but adverse events may include proteinuria. The purpose of this study was to compare the effects of sirolimus and everolimus on creatinine clearance and proteinuria after kidney transplant. MATERIALS AND METHODS: This study was a prospective evaluation period of 50 patients (age, 16-65 y) who had kidney transplant. There were 25 patients who used sirolimus and 25 patients who used everolimus. Evaluation at the beginning mTOR and end of the evaluation period included complete blood count, blood pressure, serum creatinine level, creatinine clearance, and proteinuria level in a 24-hour urine collection. RESULTS: Mean creatinine clearance at the beginning and end of the evaluation period was significantly less in the everolimus than sirolimus group. There was no significant change in creatinine clearance from the beginning to end of the evaluation period in either the sirolimus or everolimus group. Mean proteinuria at the beginning and end of the evaluation period was similar between the sirolimus and everolimus groups. Both groups had a significant increase in mean proteinuria from beginning to end of the evaluation period, but the increase in proteinuria was similar for the sirolimus and everolimus groups (difference not significant). CONCLUSIONS: In kidney transplant recipients, sirolimus and everolimus are associated with a similar level of increased mean proteinuria.

Soluble TWEAK levels are independently associated with coronary artery disease severity in patients with stage 2-3 kidney disease.

PURPOSE: Patients diagnosed with chronic kidney disease (CKD) have a greater rate of cardiovascular mortality compared with the general population. The soluble form of TNF-like weak inducer of apoptosis (TWEAK) plays a role in cellular proliferation, migration, and apoptosis. The current study aimed to analyze whether soluble TWEAK levels are associated with the severity of coronary arterial disease (CAD) in CKD patients. METHODS: Ninety-seven patients diagnosed with CKD stages 2-3 according to their estimated glomerular filtration rate and the presence of kidney injury were included in the study. Plasma sTWEAK concentrations were determined using commercially available ELISA kits. Coronary angiographies were performed through femoral artery access using the Judkins technique. RESULTS: Correlation analysis of sTWEAK and Gensini scores showed significant association (p < 0.01, r (2) = 0.287). When patients were divided into two groups with a limit of 17 according to their Gensini score, sTWEAK levels indicated a statistically significant difference (p < 0.01). CONCLUSIONS: Our results indicate a relationship between sTWEAK levels and CAD in CKD stages 2-3 patients.

Bone morphogenetic protein-7 and disease progression in renal amyloidosis patients.

INTRODUCTION: Chronic kidney disease (CKD) is an important health care problem with increasing incidence. Early diagnosis, recognition and interventions to avoid the disease progression have great value. Even some risk factors for disease progression have been described; there are still some dark spots. Transforming growth factors (TGFs), particularly bone morphogenetic protein-7 (BMP7) take place in renal fibrosis. Our study aimed to evaluate the association between serum BMP7 levels and the progression of CKD. MATERIALS AND METHODS: Our study has been conducted between January 2008 and December 2010. Decrease in GFR by 10%, doubling of serum creatinine and need for renal replacement therapy have been set as progression end-points. Totally 93 patients (48 female, 45 male) have been included. Baseline and end of follow-up BMP7 levels have been measured. RESULTS: At the end of the follow-up, 46 of 93 patients have been considered as having progressive CKD. Higher levels of serum BMP7 levels have been found to be associated in progressive kidney disease. DISCUSSION: Our results showed that BMP7 levels were higher in patients with progressive CKD, and also BMP7 to be associated with CKD progression. But this relationship was not statistically significant. In patients with progressive CKD, higher levels of proteinuria and blood pressure have been previously described. The effect of BMP7 on kidneys is not still clear, it is hypothesized that TGF-beta1 inhibition may alter renal fibrosis.

Complete reversal of nephrotic syndrome secondary to amyloidosis with use of infliximab in a patient with inflammatory bowel disease and ankylosing spondylitis.

A 30-year-old woman was diagnosed with ulcerative colitis in January 2006. One year later, she presented because of severe back pain and was diagnosed with ankylosing spondylitis (AS). In February 2008, the patient, while still under standard treatment for ulcerative colitis and AS, was admitted because of massive proteinuria and related symptoms. Nephrotic syndrome was observed and renal biopsy revealed amyloid deposits. After treatment with infliximab, nephrotic syndrome disappeared. We aim to present a case of secondary amyloidosis complicating ulcerative colitis and associated spondyloarthropathy.

The effect of peripheral blood values on prognosis of patients with locally advanced gastric cancer before treatment.

We aimed to investigate the prognostic significance of neutrophil, lymphocyte, platelet, mean platelet value (MPV), platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) in patients with locally advanced gastric cancer (LAGC). One hundred sixty-eight patients with LAGC who had been followed-up between 2004 and 2008 were included in present study. The results of hematological (platelet, lymphocyte, neutrophil and MPV) and biochemical (uric acid and LDH) parameters were evaluated before treatment. NLR was divided into two groups as <2.56 and ≥2.57 and PLR was also divided into two groups as ≤160 and >160. Platelet counts and lymphocyte counts were also divided into two groups; ≤300.000/mm3 and >300.000/mm3, and <1,500/mm3 and ≥1,500/mm3, respectively. Results were evaluated with Kaplan-Meier and Long-rank tests. The mean age of patients at diagnosis was 60.1±12.1 and 114 of patients (67.8%) were male. For 168 patients, 48 months overall survival (OS) rate was 45.2% and the median OS was 39 months (range 33-44). In patients whose PLR was less than 160 (n=54), the median OS was 45 months (range 38-52) and also for cases whose PRL was greater than 160 (n=114), the median OS was 27 months (range 22-32) (p=0.006). While for fifty patients whose lymphocyte counts were less than 1,500, the median OS was 27 months (range 21-33), in cases with high lymphocyte counts (≥1,500) (n=118), it was 41 months (range 35-48) (p=0.03). The median OS was 41 (range 34-48) and 30 (range 23-37) months in two platelets groups, respectively (p=0.24). However, in the patients whose NLR was less than 2.56 (n=107), median OS was better than with cases whose NLR was greater than or equal to 2.56 (42 vs. 27 months). Routine peripheral blood counts may be useful prognostic factor for evaluating the accuracy of risk stratification in patients with radically resected gastric cancer Our results need to be confirmed by study including larger sample size in future.
