Introduction: Premature neonates demonstrate difficulties with swallowing due to neurological immaturity as well as a weaker suck reflex compared to full term infants. Swallowing starts to mature by 33-34 weeks of gestational age. In neonates, dysphagia is evaluated clinically by speech-language pathologists and a swallow study is ordered for infants with swallowing difficulties. However, leaving the NICU to undergo a swallow study puts infants under environmental stressors and a swallow study exposes infants to radiation. There is a concern that swallow studies are being over-utilized in the NICU., Methods: All premature infants born before 36 weeks GA admitted to the Sanford Boekelheide NICU between January 2015 and December 2019 who underwent a swallow study were enrolled in data analysis. Deidentified data was collected retrospectively through electronic medical record review and RedCap was utilized for data storage. Infants were divided in two cohorts; those who underwent a feeding change (feeding thickening) following a swallow study vs those who continued with prior feedings. Infant demographics and characteristics were assessed to identify a group of infants who are at high risk of aspiration., Results: A total of 179 infants were identified., Discussion: A swallow study can identify infants at high risk for aspiration, however, many could potentially be avoided by allowing more time for infant maturation., (Copyright© South Dakota State Medical Association.)

Introduction: Baltic States including Latvia are reported as having one of the highest renal cell carcinoma (RCC) incidence and mortality rates in the world. However, data are often presented without stage-specific stratification, making assessment of the overall RCC diagnosis and survival trends challenging., Material and Methods: We collected data on all newly diagnosed RCC patients from the national population-based cancer registry between 1997 and 2016. We analyzed RCC incidence, mortality and survival trends using Joinpoint analysis. Kaplan-Meier analysis was performed for 5- and 10-year cancer specific survival rate calculations., Results: There were a total of 7893 patients with newly diagnosed RCC. The age standardized (AS) incidence rate (per 100,000) increased slightly from 8.9 in 1997 to 9.8 in 2016. There were no specific changes in the incidence rate trend. Detection of early stage RCC increased by 5.4% annually. The AS mortality rates (per 100,000) decreased from 4.9 in 1997 to 3.9 in 2016, however, it did not reach a statistically significant change. The mortality rates decreased significantly in females and in the age group of 60-69 years. The 5-year cancer specific survival (CSS) rate increased from 55.1% in 1997-2001 to 66.6% in years 2007-2011. The 10-year CSS rate increased from 49.1% in 1997-2001 to 56.5% in years 2002-2006., Conclusions: During the study period, RCC incidence rates increased and overall mortality rates did not change. Similar to the rest of the world, the incidence of RCC diagnosed at an earlier stage increased and 5- and 10-year survival rates improved., Competing Interests: The authors declare no conflicts of interest, (Copyright by Polish Urological Association.)
