Malnutrition-Inflammation Score: A Valid Tool to Assess Nutritional Status in Patient with End-stage Renal Disease

Nutritional assessment is a basic and necessary process in the nutritional management of dialysis patients. Malnutrition is a prevalent complication in patients on maintenance hemodialysis (HD). The study aimed to evaluate its relationship with the duration of dialysis, demographic and socioeconomic profile of HD patients, and to assess malnutrition inflammation score (MIS) in HD patients. In this descriptive-analytical study, 153 HD patients were selected with random sampling. All the patients were interviewed and the MIS of the patients was recorded. Evaluate the relationship of malnutrition with the duration of dialysis, demographic and socioeconomic profile of HD patients, and to assess MIS in HD patients. Patients were followed up for 3 months. Data were analyzed with Chi-square and t-tests and Pearson correlation coefficient. A total of 153 patients were studied, 53 (34.64%) patients had good nutritional status and 100 (65.35%) patients had malnutrition. The mean of patients MIS score was 10.71 ± 5.14. Malnutrition rates in males and females were not significantly different. There was a positive and significant relationship between age and MIS score (P = 0.035). There was also a significant correlation between the level of education and MIS score (P = 0.042). The mean dialysis duration was 25.52 ± 2 6.27 months. There was a significant difference in the duration of dialysis in mild to severely malnourished patients (P = 0.002). A significant correlation between MIS score and the serum calcium and serum iron results (r = 0.402). The rise in serum prealbumin level was significantly greater at 3 months. MIS score is the best tool to assess nutritional status in patients with ESRD undergoing HD, because it can recognize various degrees of malnutrition that may remain undetected by a single laboratory assessment. The correlation between MIS score and age and dialysis period was significant

Top 100 Most Cited Papers in Laser-Assisted in situ Keratomileusis Surgery: A Bibliometric Analysis

PURPOSE: To conduct a bibliometric analysis of the 100 most cited publications on LASIK using the Scientific Information (ISI) Web of Knowledge database. METHODS: This analysis used keyword-specific searches within the Web of Science database to isolate the 100 most frequently cited LASIK articles published between 1996 and 2019 (T100). Number of citations per article and per year were quantified from 1996 to 2019. Title, authors (as well as affiliated institutions and countries of origin), journal, year of publication, and citation frequency were variables analyzed. RESULTS: Of the T100 articles, each article was cited between 103 to 411 times with a mean of 167 citations. Between 0-11 articles in the T100 were published every year on average with a median of 5 publications per year. The highest concentration of T100 publications occurred between 2003 and 2008 at 51%. A decrease in the annual publication rate of influential articles was observed after 2010 at 23%; 39.1% of these articles compared LASIK to newer refractive surgical approaches. The highest number of T100 articles were from the Journal of Refractive Surgery. The University of California System produced the highest number of T100 articles. The author with the most articles in the T100 is Dan Z. Reinstein. Most T100 articles originated from the United States. CONCLUSION: The peak of influential LASIK research occurred between 2000-2010, likely due to topics such as postprocedural corneal ectasia and the femtosecond laser approach. While newer surgical techniques such as SMILE may have contributed to the decline in the annual rate of LASIK-related publication, the underlying cause for this decline is unclear

Impact of Cochlear Dose on Hearing Preservation Following Stereotactic Radiosurgery in Treatment of Vestibular Schwannomas: A Multi-center Study

BACKGROUND: Stereotactic radiosurgery (SRS) is a well-established treatment for vestibular schwannomas (VS). Hearing loss remains a main morbidity of VS and its treatments, including SRS. Effects of radiation parameters of SRS on hearing remain unknown. OBJECTIVES: The goal of this study is to determine the effect of tumor volume, patient demographics, pre-treatment hearing status, cochlear radiation dose, total tumor radiation dose, fractionation, and other radiotherapy parameters on hearing deterioration. METHODS: Multicenter retrospective analysis of 611 patients who underwent SRS for VS from 1990-2020 and had pre- and post-treatment audiograms. RESULTS: Pure tone averages (PTA)s increased and word recognition scores (WRS)s decreased in treated ears at 12-60 months while remaining stable in untreated ears. Higher baseline PTA, higher tumor radiation dose, higher maximum cochlear dose, and usage of single fraction resulted in higher post radiation PTA; WRS was only predicted by baseline WRS and age. Higher baseline PTA, single fraction treatment, higher tumor radiation dose, and higher maximum cochlear dose resulted in a faster deterioration in PTA. Below a maximum cochlear dose of 3 Gy, there were no statistically significant changes in PTA or WRS. CONCLUSION: Decline of hearing at 1 year in VS patients after SRS is directly related to maximum cochlear dose, single versus 3-fraction treatment, total tumor radiation dose, and baseline hearing level. The maximum safe cochlear dose for hearing preservation at 1 year is 3 Gy, and the use of 3 fractions instead of 1 fraction was better at preserving hearing
