PURPOSE: The aim of this study was to evaluate the correlations between laboratory findings and ultrasonographic measurements of renal length and cortical thickness in patients receiving follow-up for chronic kidney disease (CKD). METHODS: A total of 41 CKD patients (18 males and 23 females; mean age, 65.2 years; range, 42 to 85 years) with a low glomerular filtration rate who did not require renal replacement therapy were included in this prospective study. Patients were followed up with laboratory assays at bimonthly intervals and with ultrasonography performed twice a year. Renal cortical thickness, renal length, and estimated glomerular filtration rate (eGFR) values were compared using the paired-samples t test. Additionally, Pearson correlation analysis was conducted between renal length and cortical thickness measurements and eGFR values to assess kidney function. RESULTS: At the beginning of the study and after 24 months, mean eGFR values of the 41 patients were 35.92 mL/min and 28.38 mL/min, respectively. The mean renal length was 91.29 mm at the beginning of the study and 90.24 mm at the end of the study. The mean cortical thickness was 5.76±2.05 mm at the beginning of the study and 5.28±1.99 mm at the end of the study. A statistically significant positive association was found between eGFR and mean renal length (r=0.66, P < 0.01) and between eGFR and mean cortical thickness (r=0.85, P < 0.01), with the latter being more prominent. CONCLUSION: Our study suggests that ultrasonographic cortical thickness measurements may be an important imaging technique in the follow-up care of patients with CKD.

Purpose:
The main purpose of this study is to evaluate prognostic factors that affected the patients’ early (<30 days) and late (six months, one year, and overall) postoperative mortality following hip fracture surgery.
Materials and Methods:
This retrospective study included 515 patients older than 75 years old with surgically treated osteoporotic hip fracture. The demographic data, American Society of Anesthesiologists (ASA) classification, type of anesthesia, duration of hospital stay, and history of intensive care unit (ICU) stay were collected.An analysis of laboratory values was also performed to determine their relationship with mortality. The primary outcome was survival, determined as the time from the surgery to death or the end of the study. The patients were divided into four groups according to survival time: at the first month, six months, first year, and overall survival. An analysis of demographic and laboratory values was performed to determine their validity as prognostic factors for each group.
Results:
Postoperative C-reactive protein (CRP) level showed an independent association with a poor survival at the first month. ASA classification, admission to the ICU, and preoperative CRP levels showed an independent association with a poor survival for the first six months. Preoperative CRP level showed an independent association with a poor survival for the first year. ASA classification, admission to the ICU, and the preoperative CRP levels showed an independent association with a poor overall survival.
Conclusion
CRP level, a high ASA classification, and postoperative ICU admission were related to poorer overall survival rate following hip fracture surgery in the elderly.

Objective:
The use of noninvasive volume assessment methods to predict acute blood loss in spontaneously breathing patients remains unclear. We aimed to investigate changes in the pleth variability index (PVI), vena cava collapsibility index (VCCI), end-tidal carbon dioxide (EtCO2), pulse pressure (PP), and mean arterial pressure (MAP) in spontaneously breathing volunteers after acute loss of 450 mL blood and passive leg raise (PLR).
Methods:
This prospective observational study enrolled healthy volunteers in the blood donation center of an academic hospital. We measured the PVI, EtCO2, VCCI, MAP, and PP before blood donation; at the 0th and 10th minute of blood donation; and after PLR. The primary outcome was the changes in PVI, EtCO2, VCCI, MAP, and PP.
Results:
We enrolled thirty volunteers. There were significant differences among the four obtained measurements of the PVI, EtCO2, and MAP (P<0.001, P<0.001, P<0.001, respectively). Compared to the predonation values, post-hoc analysis revealed an increase in the PVI at the 0th min postdonation (mean difference [MD], 5.4±5.9; 95% confidence interval [CI], -7.6 to -3.1; P<0.001); a decrease in the EtCO2 and MAP at the 0th and 10th minute postdonation, respectively (MD, 2.4±4.6; 95% CI, 0.019 to 4.84; P=0.008 and MD, 6.4±6.4; 95% CI, 3 to 9.7; P<0.001, respectively). Compared with EtCO2 at the 10th minute, the value increased after PLR (MD, 1.8±3.2; 95% CI, 0.074 to 4.44; P=0.006).
Conclusion
The PVI and EtCO2 could detect early hemodynamic changes after acute blood loss. However, it remains unclear whether they can determine volume status in spontaneously breathing patients.

Objective:
The history, electrocardiogram, age, risk factors, troponin (HEART), the thrombolysis in myocardial infarction (TIMI), and Global Registry of Acute Coronary Events (GRACE) scores are useful risk stratification tools in the emergency department (ED). However, the accuracy of these scores in the cancer population is not well known. This study aimed to compare the performance of cardiac risk stratification scores in cancer patients with suspected acute coronary syndrome (ACS) in the ED.
Methods:
This prospective cohort study recruited patients with cancer who visited the ED because of suspected ACS. The development of any major adverse cardiac events (MACE) within 6 weeks was recorded, with the study outcome being a MACE within 6 weeks of ED admission.
Results:
A total of 178 patients participated in this study, of whom 5.6% developed a MACE. Statistically significant differences were found between the mean HEART and TIMI scores in predicting MACE. The HEART score had the highest area under the curve (0.64; 95% confidence interval, 0.48–0.81), highest sensitivity (80%), and highest negative predictive value (97.5) in patients with cancer.
Conclusion
We found a similar rate of MACE in cancer patients with low-risk chest pain compared to that in the general population. However, the HEART, TIMI, and GRACE scores had a lower performance in cancer patients with MACE compared to that in the general population.

Anaphylaxis have been documented as adverse effects of ciprofloxacin, ofloxacin, norfloxacin, levofloxacin, and moxifloxacin. However resistant and biphasic anaphlylactic reactions to gemifloxacin have not been reported to date. Management of severe anaphylaxis in the elderly can be complicated by concurrent medications such as beta (β) adrenergic, alpha (α) adrenergic blockers and angiotensin-converting enzyme (ACE) inhibitors. We report here in the case of a 60-year-old male who was taking on ACE inhibitor, α and β blockers and experienced a severe, resistant and biphasic anaphlylactic reaction to gemifloxacin mesylate.
