The prognostic impact of tumor necrosis in non-muscle invasive bladder cancer.
We aimed to investigate the impact of tumor necrosis in non-muscle invasive bladder cancer on patients' recurrence and progression rates and survival outcomes. ⋯ In this study, we demonstrated that patients with non-muscle invasive bladder cancer and tumor necrosis in pathological specimens have shorter progression-free survival and more adverse pathological features.

Serum Calcium/Phosphorus Ratio in Biochemical Screening of Primary Hyperparathyroidism.
Primary hyperparathyroidism is a common endocrine disease and most cases are asymptomatic. Currently, in a hypercalcemic patient, the first laboratory investigation is serum primary hyperparathyroidism measurement. However, the primary hyperparathyroidism level cannot be measured in many primary healthcare centers in our country. In addition, serum calcium levels are normal in normocalcemic primary hyperparathyroidism patients, even if most centers have serum calcium levels measured. Therefore, a simple and inexpensive laboratory biochemical marker is required for the diagnosis of primary hyperparathyroidism. Recently, the calcium/phosphorus ratio has been proposed as a suitable tool for diagnosing primary hyperparathyroidism. This study aimed to investigate the diagnostic value of serum calcium/phosphorus ratio in primary hyperparathyroidism screening. ⋯ The calcium/phosphorus ratio is a simple and inexpensive method for primary hyperparathyroidism screening when a cutoff value of 2.59 is used.

Effect of patellar resurfacing surgery on bleeding in total knee arthroplasty.
Postoperative bleeding is one of the most important factors affecting clinical and functional results in total knee arthroplasty. Therefore, many studies have been conducted on bleeding in arthroplasty patients. However, there are very few reports investigating the effect of patellar surface replacement on bleeding in knee arthroplasty. We, therefore, aimed to investigate the effect of patellar surface replacement on postoperative bleeding. ⋯ Patellar component application in patients who had undergone total knee arthroplasty does not change the blood loss of the patients.

C-reactive protein to lymphocyte count ratio is a promising novel marker in hepatitis C infection: the clear hep-c study.
Chronic hepatitis C (CHC) is one of the most important health problems affecting the significant rate of world population and it may lead to cirrhosis and hepatocellular carcinoma. C-reactive protein to lymphocyte count ratio (CLR) is used in estimating inflammatory burden. Therefore, this study aimed to compare CLR values between CHC patients and healthy controls and between CHC patients with and without fibrosis. ⋯ Increased CLR in patients with CHC may be an alarming finding of liver fibrosis, as CLR is associated with both CHC and hepatic fibrosis.

Predictors of left ventricular ejection function decline in young patients with ST-segment elevation myocardial infarction.
A decrease in the left ventricular ejection fraction (≤40%) in the setting of ST-segment elevation myocardial infarction is a significant predictor of mortality in the young ST-segment elevation myocardial infarction population. In this study, we aimed to investigate the predictors of left ventricular ejection fraction reduction and evaluate the long-term mortality rates in young ST-segment elevation myocardial infarction patients with or without decreased left ventricular ejection fraction. ⋯ In young ST-segment elevation myocardial infarction patients, lesion properties (left anterior descending lesion, proximally located lesion), no-reflow, and prolonged ischemia time appeared to be important determinants for the left ventricular ejection fraction decline, rather than coronary disease severity or demographic and hematological parameters. Statin use may be preventive in the development of left ventricular ejection fraction decline in young ST-segment elevation myocardial infarction patients.
