Characteristics of the Audience Reached by the National Network of Sexually Transmitted Disease Clinical Prevention Training Centers and Correlation With Sexually Transmitted Infection Rates, 2015 to 2020.

BACKGROUND: The National Network of Sexually Transmitted Disease Clinical Prevention Training Centers (NNPTC) trains clinical providers to diagnose and treat sexually transmitted infections (STIs) in the United States. The purpose of this study was to examine the demographics of clinical providers and to correlate the number of training episodes with STI rates at the county level. METHODS: Registration data were collected between April 1, 2015, and March 31, 2020, in a custom Learning Management System from clinical providers taking NNPTC training. Using the 2018 STI surveillance data, counties were divided into quartiles based on reportable STI case rates and the number of county-level training events was compared per quartile. Univariate and multivariate analyses were conducted in IBM SPSS Statistics 23 (Armonk, NY) and SAS Enterprise Guide 7.1 (Cary, NC). RESULTS: From 2015 to 2020, the NNPTC trained 21,327 individuals, predominantly in the nursing professions and working in a public health environment. In multivariate analysis, the number of training events was significantly associated with higher STI rates at the county level (P < 0.0001) and the state where a prevention training center is located (P < 0001). CONCLUSIONS: The analysis suggests that NNPTC trainings are reaching the clinical providers working in geographic areas with higher STI rates.

Quantitating Dialysis in the Home Hemodialysis Patient: A Simple and Practical Approach.

Home hemodialysis is the most cost-effective form of dialysis and is associated with the lowest mortality. Home hemodialysis patients are usually highly motivated, independent, and actively employed. Because of the minimal supervision they require and the fact that they are not in a controlled environment, it is easy to overlook the measurement of their dialysis adequacy. We studied 6 home hemodialysis patients and demonstrated that blood urea measured 30 min before the end of dialysis (Ct-30) is equivalent to that measured 30 min after the end of dialysis (Ct+30). The Kt/V results using Ct-30, Kt/V(Ct-30), were almost equivalent to Kt/V(Ct+30) (p = 0.5). The Kt/V Kt/V(Ct) using blood urea measured at the end of dialysis (Ct) significantly overestimated Kt/V(Ct-30) and Kt/V(Ct+30) (p = 0.007) The calculated percent reduction of urea (PRU) was about 5% less when using Ct-30 compared with Ct (p = 0.001). Taking blood samples 30 min before the end of dialysis for urea kinetics is more convenient for the home dialysis patients, since no other technical aspects of dialysis need their attention. The samples can be delivered to the laboratory the following day, because the blood may be stored in heparinized tubes at 4°C without deterioration of urea and creatinine concentrations. The Kt/V(Ct-30) was almost equal to Kt/V(Ct+30), so there is no longer any concern for the errors introduced by urea rebound. The blood pump must be reduced to 80 mL/min for about 10 sec to eliminate the errors due to fistula and cardiopulmonary recirculation. A simple programmable calculator will facilitate the calculation of accurate results using the Daugirdas second-generation formula.
