Abstract Context.—The effectiveness of the long-term monitoring of errors detected by frozen section–permanent section correlation is unknown. Objective.—To determine factors important in laboratory improvement in frozen section–permanent section discordant and deferral rates by participation in a multi-institutional continuous quality improvement program. Design.—Participants in the College of American Pathologists Q-Tracks program self-reported the number of anatomic pathology frozen–permanent section discordant and deferred cases in their laboratories by prospectively performing secondary review of intraoperative consultations. Laboratories participated in the program for 1 to 5 years and reported their data every quarter. We calculated mean and median discordant and deferred case frequencies and used mixed linear modeling to determine if length of participation in the program was associated with improved performance. Participants.—One hundred seventy-four laboratories self-reported data. Main Outcome Measures.—Mean frozen–permanent section discordant and deferred diagnostic frequencies and changes in these frequencies over time were measured. Results.—The mean and median frozen–permanent section discordant frequencies were 1.36% and 0.70%, respectively. The mean and median deferred diagnostic frequencies were 2.35% and 1.20%, respectively. Longer participation in the Q-Tracks program was significantly associated (P = .04) with lower discordant frequencies; 4- or 5-year participation showed a decrease in discordant frequency of 0.99%, whereas 1-year participation showed a decrease in discordant frequency of 0.84%. Longer participation in the Q-Tracks monitor was associated with lower microscopic sampling frequencies for discordant diagnoses (P = .04). Increased length of participation in the Q-Tracks program was significantly associated (P = .04) with lower deferred diagnostic frequencies. Conclusions.—Long-term monitoring of frozen–permanent section correlation is associated with sustained improvement in performance.

In this study, we evaluate the qualitative thermal performance of a groundwater borehole by monitoring the temperature at the primary (borehole) and secondary (heat pump) sides of a domestic heat pump over three heating seasons between 2010 and 2013. Based on early results, the borehole was extended during the monitoring period in order to increase performance. Our results suggest that the temperature parameters of a borehole do not remain constant and that a borehole’s properties can change significantly over time if the borehole substrate temperature is not given time to regenerate.

An inventory of chiropteran fauna was carried out in Bhubaneswar city, Odisha, eastern India during October 2015 and March 2016 following roost survey and mist net survey techniques. During the study a total 19 species of bats belonging to seven families including the nationally threatened Rhinolophus rouxii were recorded of which family Vespertilionidae was the most diverse one, represented by five species. Majority of 11 species are found roosting and breeding in old temples and caves and are vulnerable from renovation activities, persecution and tourism. Therefore, long term monitoring of these sites are essential to understand the population trend over time and derive appropriate conservation implications.

A group of 110 patients from the West Bohemian region who had been infected with COVID-19 was monitored for the purposes of this study. We focused on cases of mild or moderate COVID-19; statistically the most likely to occur. Day zero was defined as the day on which a positive PCR test was first established. The mean length of observation was 6.5 months, the maximum length 12 months. The first blood samples were taken from a smaller cohort during the 1–3 months following the first positive PCR test. We assumed that SARS-CoV-2 antibodies would be present during this period and therefore a limited number of samples were taken for the purpose of detecting antibodies. More samples were collected, starting 4 months after the first positive PCR test. A subsequent set of blood samples were drawn, mostly 6 months after the first ones. Our study confirmed the presence of total IgG SARS-CoV-2 antibodies up to 1 year after the onset of the disease. The peak of antibody production was observed in the third month after the first positive PCR test. A mathematical estimate of the median duration of antibody positivity was calculated to be 18 months from the onset of the COVID-19 infection.

Term Monitoring

The long-term monitoring of organophosphoric acid triesters started in 1976 in the Yodo River basin; Lake Biwa, Yodo River and the rivers in Osaka City. An extensive survey was also conducted in the Yamato River and Osaka Bay, Japan. This report presents the current levels and distributions of OPEs as well as the historical trend of TDCPP. Some or all of OPEs studied here have been detected in the entire water samples over the monitoring period. It was clear that OPEs were ubiquitous pollutants in the river and coastal waters. Total OPE levels ranged from 0.4 to 2.4 µgl−1 in the Yodo River basin, 2.4 to 12 µgl−1 in the rivers in Osaka City, 18 to 28 µgl−1 in the Yamato River basin and 0.1 to 1.3 µgl−1 in Osaka Bay. An apparent difference was found in the individual OPE level among the different water areas surveyed. In the Lake Biwa and the Yodo River, the predominant compound was TBXP followed by TCEP and TDCPP. The higher levels were observed for TBXP, TEP, TCPP and TCEP in the rivers in Osaka City. The highest TCPP level, which occupied more than 70% of OPEs' composition, was observed and the mean level reached to 13.1µgl−1 in the Yamato River. In Osaka Bay, 6 kinds of OPEs, except for TPP, TEHP and TCP, were found and the most prevalent compounds were TCEP and TBP. TDCPP had gradually increased in concentration in the Yodo River basin until 1987 from 1976 year by year. However, the reverse trend of TDCPP has been noticed during the last several years.

Osteoarthritis (OA) is a chronic disease that disables many aging adults. People with OA are often asked to adhere to prescribed exercise regimens that must be undertaken in the presence of pain and other disease-related symptoms. We conducted a review of literature that focused on what is known about exercise adherence and the factors that influence exercise adherence among people with OA. Results revealed multiple determinants of exercise adherence; however, these determinants have not been carefully studied in the context of exercise adherence and OA. Almost all studies of exercise adherence among people with OA are short-term and do not use validated measures of adherence. Moreover, poor adherence is the most compelling explanation for the declining impact of the benefits of exercise over time. We conclude that interventions to enhance self-efficacy, social support, and skills in long-term monitoring of progress are necessary to foster exercise adherence among people with OA.
