Corneal densitometry in patients with arcus senilis and its correlation with serum lipid levels.

Purpose: To evaluate corneal densitometry (CD) of patients with arcus senilis (AS) and its association with the serum lipid markers. Methods: This is a cross-sectional, case-control study. The AS diagnosis was made clinically. Forty-five eyes of 45 patients with AS and 38 eyes of 38 age-matched control subjects with no noticeable AS were enrolled in the study. All participants underwent detailed ophthalmologic examination along with corneal Scheimpflug imaging with CD measurement. The evaluated serum lipid markers of the participants included total cholesterol, triglyceride, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very-low-density lipoprotein (VLDL). The Spearman correlation analysis was used to correlate the serum lipid values and the CD. P < 0.05 was defined as statistically significant. Results: The male to female ratio was 26/19 and 14/24 in the study and control groups, respectively (P = 0.057). The mean age was 59.56 ± 8.7 and 56.47 ± 8.6 years in the study and control groups, respectively (P = 0.117). The mean total CD values in the zones extending from 2 to 12 mm were higher in the study group than in the control group (P < 0.001). The serum HDL level was found to be significantly decreased in the study group compared to the control group (P = 0.048 and Z = -1.976). There was a significant positive correlation between the serum triglyceride level and the CD value of the outermost zone (10-12 mm) (r = 0.334 and P = 0.025). Conclusion: The CD of patients with AS was found to increase not only in the peripheral zone but also in the cornea's paracentral zone compared to the healthy controls. The serum triglyceride level should give an insight into the intensity of arcus senilis. The serum HDL levels were decreased in patients with AS.

Experiences of Turkish Parents of Hospitalized Children With Cancer During the COVID-19 Pandemic: A Qualitative Study.

PURPOSE: To describe the experiences of Turkish parents of hospitalized children with cancer during the COVID-19 pandemic. PARTICIPANTS & SETTING: Participants were recruited at the pediatric hematology-oncology clinic of a university hospital in Turkey. A purposive sampling strategy was used to identify participants. Parents who had a child aged 0-18 years with cancer were eligible. METHODOLOGIC APPROACH: This study was conducted using a descriptive qualitative research design. Semistructured individual interviews with 14 parents of children with cancer were used for data collection. Data were analyzed using the content analysis method. FINDINGS: Two main themes with related subthemes were identified that revealed the lived experiences of parents of children with cancer. IMPLICATIONS FOR NURSING: Pediatric oncology nurses can develop clinical practices that help parents to cope with anxiety about COVID-19. Nurses should share with parents current and valid information about the child's care during the pandemic. Future research should examine the experiences of children with cancer and their parents from different cultures during the COVID-19 pandemic.

Investigation of the Factors Affecting Allograft Kidney Functions: Results of 10 Years.

INTRODUCTION: Significant improvements in patient and graft survival and reductions in the frequency of acute rejection were obtained in the early period after renal transplantation, but this success was not sufficiently reflected in the long term. Allograft kidney losses in the long term remain a significant problem. In this study, we investigated the specific causes of graft losses in patients who had a good clinical course in the first year but developed graft loss in the long term. METHODS: A total of 118 patients who underwent kidney transplantation in 2005 and 2006 in the Organ Transplantation Center of Ege University Medical Faculty Hospital were evaluated. The inclusion criteria were to be older than 18 years and have a serum creatinine value of <2 mg/dL at the 12th month after transplantation. RESULTS: Sixty-one percent of the recipients were male, and the mean age at the time of transplantation was 34 ± 11 years (18 to 61). We observed 29 graft losses during the mean follow-up period of 129 ± 35 months (27 to 162). Three of the graft losses were death by functional graft. Of the 26 patients with graft loss, 16 had chronic rejection, and 8 had recurrent glomerulonephritis. The relationship between nonimmune causes and graft loss was not detected. CONCLUSIONS: In conclusion, nonimmune factors may not be as important as we think in relatively young and healthier recipients. Chronic rejection and recurrent glomerulonephritis are the main causes of long-term graft loss of patients with good graft function at the end of the first year. Improvement of long-term survival will be possible with the prevention and effective treatment of these 2 problems.
