Investigation of the Parameters That May Predict Hemodialysis Frequency

DergiPark: 819242tmsjAims: This study investigates the relationship between the clinical parameters at the beginning of hemodialysis therapy and the changing in the frequency of weekly hemodialysis sessions in ongoing treatment. Methods: The study population was composed of all of the patients that were started chronic hemodialysis treatment between January 2015 and January 2020. The patients were classified as twice-weekly (2/7) and thrice-weekly (3/7) groups according to the hemodialysis schedule at the start of treat- ment. The 3/7 group is additionally subdivided according to the dialysis schedule switches to the thrice-weekly program. Basal demographics and biochemical parameters were obtained from medical records at the start of hemodialysis. Results: The total number of subjects in the study was 433 (141 in the twice-weekly program, 292 in the thrice-weekly program). Forty-six (32.6%) patients in twice-weekly hemodialysis program were shifted to a thrice-weekly program during the follow-up. The female/ male ratio in the 2/7 program is different from the 3/7 program. Serum creatinine and C-reactive protein levels were higher in patients on the 3/7 program. Serum calcium and albumin levels were higher in patients on a 2/7 program. The statistically sig- nificant increments were found in calcium, hemoglobin, hematocrit, urea, creatinine, and potassium levels between the before and after switch results of the 3/7 group which switched from 2/7. Conclusion: Urea, creatinine, and potassium levels can guide the decision to compose a hemodialysis schedule. However, patients' future weekly treatment schedules cannot be predicted by biochemical parameters obtained at the start of hemodialysis

Deceased donor kidney allocation schemes and international exchange

PURPOSE OF REVIEW: In this review, we summarize different allocation schemes around the world and identify ways to exchange organs between countries. RECENT FINDINGS: The primary goal of transplantation is prolongation of patient survival and an improved quality of life. Most allocation systems try to match the potential survival of the organ with the life expectancy of its recipient. Kidney transplantation enables cost reductions by the avoidance of dialysis for the healthcare system, which is sometimes the driving force for state interventions to enhance donor recruitmentThe major benefit from international exchange is the possibility to transplant highly sensitized patients or patients with rare HLA allele.In a broad international exchange system, there are three possibilities: exchange of surplus organs, exchange of organs to support patients with a potentially excessive waiting time because of HLA antibodies or rare alleles, and exchange of organs to make the best possible match between donor and recipient. SUMMARY: It is possible to shape a hierarchical allocation scheme, which could be applicable in the majority of populations despite different geographical and socioeconomic conditions: allocation to recipients with special requirements (high-urgency, highly sensitized); identification of a within the region/country; in case no suitable recipient can be identified, offer countrywide or between countries; for every organ transferred to another country, there must be an obligation to give one back

DETERMINATION OF SPATIAL VARIATION OF REFERENCE EVAPOTRANSPIRATION CASE STUDY OF SEYHAN BASIN

Geographic Information Systems (GIS) are computer-based tools for mapping and analyzing features and events onearth. GIS technology integrates common database operations such as query and statistical analysis with the uniquevisualization and geographic analysis benefits offered by maps Evapotranspiration mapping with classical methodsmay take months and even years based on the size of the area to be mapped. However, recently developed methodsdecreased the time consumed for such mapping practices to minutes. Geostatistical methods are the most commonlyused methods for mapping over large areas in a short time. In present study, Reference Evapotranspiration (ETo) valueswere calculated by ASCE Standardize Penman Monteith method using long-term climate data in the Seyhan basin. Thecalculated ETo values were mapped for April, May, June, July, August, September and yearly total by usinggeostatistical methods. It was used 7 stations in basin and 9 stations out of basins for calculation. In the production ofgeostatistical maps, cokriging was used as interpolation method and spherical model was used for model of semivariogram. At the end of the study, it was determined that ETo maps could be produced with reliable this method andmodel.&nbsp;</p
