Abstract Objective The content of websites for fellowship programs is an important source of information for residents applying to breast imaging fellowship programs (BIFPs). The purpose of this study is to evaluate the comprehensiveness of online content of BIFPs. Methods A list of BIFPs was obtained from the Society of Breast Imaging website. Each program’s website was evaluated for the presence of 19 training-relevant content variables. Impact of program characteristics on comprehensiveness scores was determined. For statistical analysis, Kruskal–Wallis tests were used to assess differences in comprehensiveness scores based upon region, and two-tailed t-tests were used to compare based upon program size. Results A total of 79 BIFP websites were analyzed. The mean comprehensiveness score of BIFP websites based on meeting the 19 criteria was 44.1% (8.4 ± 2.7/19). Program coordinator contact information (72/79, 91.1%), application requirements (71/79, 89.9%), and faculty information (56/79, 70.9%) appeared on >70% of websites. The majority of fellowships had a dedicated webpage for their program (71/79, 89.9%). Information regarding 12 of the 19 criteria appeared on fewer than 50% of websites. Program region (P = 0.32) and size (P = 0.16) were not associated with any differences in mean comprehensiveness score. Additionally, there was no significant difference in scores associated with filling all available positions for the 2020 match cycle (P = 0.77). Conclusion There is a paucity of information commonly sought out by applicants on the websites of most BIFPs. Both programs and applicants may mutually benefit from increasing comprehensive online content.

A longitudinal study of urinary 17-OHCS in 16 depressive patients showed mean values within the accepted normal range. There were no significant differences between pre-treatment and post-treatment values; only the female patients showed a tendency to have somewhat lower post-treatment levels. 17-KS output was measured in 18 depressive patients. The mean values were within the normal range. There was no significant difference between pre-treatment and post-treatment values although the female patients displayed a tendency towards somewhat lower levels following treatment. DHA and EA excretion were measured in 9 depressive patients. There was a very wide variance in the findings. There was no significant difference between pre-treatment and post-treatment levels. The significance of the above findings is discussed. It is considered that measurements of urinary excretion of corticosteroids in affective disorders constitute a limited source of information.

Customer Satisfaction And Loyalty

The hospitality industry in general and hotels in particular attend to diverse guests and their expectations. The satisfaction of all hotels guests and retaining them as a loyal customer, given their different profiles, is imperative but challenging to the sector. This study aims to address this very issue by trying to establish the relationship amongst, customer satisfaction, loyalty, demographic and tripographic attributes by focusing on the hotel guests who stayed in star rated hotels in Ethiopia. Satisfaction was measured as satisfaction with the product, satisfaction with the employees and overall satisfaction. Likewise, customer loyalty was measured with the likelihood of customers to return to the same hotel in the future. “A total of 1200 questionnaires distributed to 40 hotels out of which 415 hotel guests responded, by completing the questionnaires”. “The result of inferential statistical techniques reveals that there were significant positive relationships between the customer satisfaction variables” (products .488; p<0.001; staff .460; p<0.001), and the customer’s willingness to stay in the same hotel again.” Though all variables of “customer satisfaction affected customer loyalty, the overall satisfaction variable had the highest standardized coefficient (0.328) with a statistical significance (p < 0.01), followed by satisfaction with the product (.227, p<.01), and satisfaction with employees (.190, p<.01). There was also no statistically significant difference (p>.05) in the mean scores of the customer satisfaction and loyalty across the gender, age, marital status and employment type groups of respondents. With regards to the tripographic variables, there was a statistically significant difference (P<.05) in the mean scores of both the customer satisfaction and loyalty across the staying preference of rated hotel types of customers. Additionally, there was a statistically significant difference (p>.05) in the mean scores of customer loyalty across a source of information on the hotel group of respondents. Hotel managers in Ethiopia need to look at the importance of segmentation of guest based on their demographics and tripographic factors so that they provide personalized service to enhance their customers’ satisfaction that could lead to their loyalty.

Background Five-megapixel (MP) displays are recommended as soft copy devices for digital mammogram. An 8-MP liquid crystal display (LCD) (two 4-MP displays within one display) might offer the advantage of being able to view biplane mammography more easily than the dual planes of 5-MP LCDs. Purpose To compare detectability of Breast Imaging Reporting and Data System (BI-RADS) category 3 or higher lesions and reading time on mammography between 5- MP and 8-MP LCDs. Material and Methods The mammograms of 240 breasts of 120 patients including 60 breasts with BI-RADS category 3 or higher lesions and 180 breasts with normal or category 2 lesions were enrolled. All bilateral mammograms were displayed on bifacial 5-MP LCDs or an 8-MP LCD (two 4-MP displays within one display). Six radiologists assessed 240 breasts on each display. The observations were analyzed using receiver operating characteristic (ROC) analysis. A jack-knife method was used for statistical analysis. We employed a paired t-test to determine whether any significant differences existed in the reading time between two different displays. A P value < 0.05 was considered significant. Results The mean areas under the ROC curve obtained using 5-MP and 8-MP LCDs were 0.925 and 0.915, respectively, and there was no significant difference ( P = 0.46). There was also no significant difference in the reading time between two types of displays (57.8 min. vs. 51.5 min, P = 0.39). Conclusion The detectability of BI-RADS category 3 or higher lesions and reading time using an 8-MP LCD were comparable to those using a 5-MP LCD.

Background: Increasing amounts of diabetes-focused content is being posted to YouTube with little regulation as to the quality of the content. Diabetic education has been shown to reduce the risk of ulceration and amputation. YouTube is a frequently visited site for instructional and demonstrational videos posted by individuals, advertisers, companies, and health-care organizations. We sought to evaluate the usefulness of diabetic foot care video information on YouTube. Methods: YouTube was queried using the keyword phrase diabetic foot care. Original videos in English, with audio, less than 10 min long within the first 100 video results were evaluated. Two reviewers classified each video as useful or nonuseful/misleading. A 14-point usefulness criteria checklist was used to further categorize videos as most useful, somewhat useful, or nonuseful/misleading. Video sources were categorized by user type, and additional video metrics were collected. Results: Of 87 included videos, 56 (64.4%), were classified as useful and 31 (35.6%) as nonuseful/misleading. A significant difference in the mean length of useful videos vs nonuseful/misleading videos was observed (3.33 versus 1.73 min; P &lt; .0001). There was no significant difference in terms of popularity metrics (likes, views, subscriptions, etc) between useful and nonuseful/misleading videos. Conclusions: This study demonstrates that although most diabetic foot care videos on YouTube are useful, many are still nonuseful/misleading. More concerning is the lack of difference in popularity between useful and nonuseful videos. Podiatric physicians should alert patients to possibly misleading information and offer a curated list of videos.

Category: Other Introduction/Purpose: Academic productivity within orthopaedic subspecialties is important in developing generalizable knowledge, challenging biases, and evolving practice management. Productivity is linked to academic status and can affect compensation. This study evaluated the research activity of faculty at foot and ankle surgery fellowship programs in the United States and associated Canadian programs. The primary objective was to describe the publishing productivity of American Orthopaedic Foot & Ankle Society (AOFAS) fellowship faculty. Methods: Program characteristics from orthopaedic foot and ankle fellowship programs across the United States and Canada were collected from AOFAS and each program’s respective websites. The studied faculty characteristics consisted of years in practice, academic rank, extent of training, and gender. Specific program characteristics were recorded, including Accreditation Council for Graduate Medical Education approval, academic affiliation, fellow research requirement, number of fellows, number of associated faculty members. Data analysis of faculty productivity (Publications, number of publications in specific journals, number of citations, and Hirsch index [h index]) was gathered using the Scopus database. Results: A total of 48 AOFAS foot and ankle surgery fellowship programs were identified with an associated 185 faculty members. The mean number of publications per faculty member was 44.9 (sd 53.0; range 0-323) with a mean h-index of 11.9 (sd 10.6; range 0-54). One-hundred and forty-four (77.8%) academic-affiliated faculty had a significantly greater number of publications (p<0.01), total citations (p<0.05), and publications in FAI (p<0.05), JBJS (p<0.05), CORR (p<0.05), and JAAOS (p<0.05) compared to the 41 (22.2%) nonacademic faculty. Nonacademic faculty maintained a h-index of 9.5 (95% CI 7-12), while academic faculty had a h-index of 12.6 (95% CI 11-14), which did not meet statistical significance (p=0.062). There were no significant differences between measures of publication productivity in male and female faculty, except for maximum citations in a single paper (67.1 vs 142.3; p<0.05) Conclusion: Academic-affiliated foot and ankle fellowship faculty have higher research productivity than non-academic surgeons. The mean h-index of foot and ankle fellowship faculty was 11.9, which is lower than that reported in sports, joints, and spine fellowship faculty but higher than that reported for hand fellowship faculty. The analyses presented can aid foot and ankle surgeons in assessing their academic productivity. [Table: see text]

Left ventricular function including regional wall motion (RWM) was evaluated by 99mTc first-pass and equilibrium gated blood pool ventriculography and glycohemoglobin (HbA1c) blood levels determined by a quantitative column technique in 25 young patients with insulin-dependent diabetes mellitus without clinical evidence of heart disease, and in healthy controls matched for age and sex. Phase analysis revealed abnormal RWM in 19 of 21 diabetic patients. The mean left ventricular global ejection fraction, the mean regional ejection fraction and the mean 1/3 filling fraction were lower and the time to peak ejection, the time to peak filling and the time to peak ejection /cardiac cycle were longer in diabetics than in controls. We found high HbA1c levels in all diabetics. There was no significant difference between patients with and without retinopathy and with and without peripheral neuropathy in terms of left ventricular function and HbA1c levels.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.

SummaryFour thromboplastin reagents were tested by 18 laboratories in Europe, North-America, and Australasia, according to a detailed protocol. One thromboplastin was the International Reference Preparation for ox brain thromboplastin combined with adsorbed bovine plasma (coded OBT/79), and the second was a certified reference material for rabbit brain thromboplastin, plain (coded CRM 149R). The other two thromboplastin reagents were another rabbit plain brain thromboplastin (RP) with a lower ISI than CRM 149R and a rabbit brain thromboplastin combined with adsorbed bovine plasma (RC). Calibration of the latter two reagents was performed according to methods recommended by the World Health Organization (W. H. O.).The purpose of this study was to answer the following questions: 1) Is the calibration of the RC reagent more precise against the bovine/combined (OBT/79) than against the rabbit/plain reagent (CRM 149R)? 2) Is the precision of calibration influenced by the magnitude of the International Sensitivity Index (ISI)?The lowest inter-laboratory variation of ISI was observed in the calibration of the rabbit/plain reagent (RP) against the other rabbit/plain reagent (CRM 149R) (CV 1.6%). The highest interlaboratory variation was obtained in the calibration of rabbit/plain (RP) against bovine/combined (OBT/79) (CV 5.1%). In the calibration of the rabbit/combined (RC) reagent, there was no difference in precision between OBT/79 (CV 4.3%) and CRM 149R (CV 4.2%). Furthermore, there was no significant difference in the precision of the ISI of RC obtained with CRM 149R (ISI = 1.343) and the rabbit/plain (RP) reagent with ISI = 1.14. In conclusion, the calibration of RC could be performed with similar precision with either OBT/79 or CRM 149R, or RP.The mean ISI values calculated with OBT/79 and CRM 149R were practically identical, indicating that there is no bias in the ISI of these reference preparations and that these reference preparations have been stable since their original calibration studies in 1979 and 1987, respectively.International Normalized Ratio (INR) equivalents were calculated for a lyophilized control plasma derived from patients treated with oral anticoagulants. There were small but significant differences in the mean INR equivalents between the bovine and rabbit thromboplastins. There were no differences in the interlaboratory variation of the INR equivalents, when the four thromboplastins were compared.

This study investigated the boreal digging frog, Kaloula borealis, to determine the egg hatching period and whether the hatching period is affected by incubation temperature. The results of this study showed that all the eggs hatched within 48 h after spawning, with 28.1% (±10.8, n=52) hatching within 24 h and 99.9% (±0.23, n=49) within 48 h after spawning. A significant difference was noted in the mean hatching proportion of tadpoles at different water temperatures. The mean hatching rates between 15 and 24 h after spawning was higher at a water temperature of 21.1 (±0.2) °C than at 24.1 (±0.2) °C. These results suggest that incubation temperature affected the early life stages of the boreal digging frog, since they spawn in ponds or puddles that form during the rainy season.
