METHODS: Computed tomography scans of 102 wrists from 51 healthy individuals were analyzed using a virtualization software. Four anatomical parameters at the distal radius sigmoid notch, namely, the radius of curvature, depth, version angle, and sagittal slope were measured. Morphological patterns of the sigmoid notch surface were identified. The results were statistically analyzed to assess the reliability of the technique and were compared with previously published literature.
RESULTS: Comparing our findings with previously published values, our study revealed a slightly larger radius of curvature and sagittal slope, while revealing a smaller depth and version. We identified the S-type, C-type, and ski-slope morphological variants. The flat-face morphological variant, however, was not identified. The sigmoid notch at the left and right wrists were similar, except for the radius of curvature.
CONCLUSION: This study demonstrates a noninvasive, fast, reliable, and reproducible technique for analyzing the sigmoid notch of the distal radius. In wrist injuries with intact distal radius sigmoid notch but involving comminuted fractures of the ulnar head, ulnar head replacement may be indicated. In such cases, analysis of the ipsilateral intact sigmoid notch would allow us to prepare an ulnar head prosthesis of appropriate size.
PATIENTEN UND METHODEN: Sechs Monate postoperativ wurde bei allen Patienten das klinische Ergebnis nach den Crawford-Kriterien, die Schmerzen anhand einer visuellen Analogskale (VAS) und der DASH-Score ermittelt. Zusätzlich wurden die aktive Beweglichkeit und das Extensionsdefizit im Endgelenk sowie aufgetretene Komplikationen festgehalten.
ERGEBNISSE: Patienten der Gruppe 1 hatten eine signifikant bessere Beugung im Fingerendgelenk, aber auch ein signifikant größeres Extensionsdefizit, obwohl sie signifikant früher ihre Arbeit wiederaufnahmen. Nach den Crawford-Kriterien erzielten 71 % der Patienten der Gruppe 1 und 100 % der Gruppe 2 ein exzellentes und gutes Ergebnis. Keine Unterschiede konnten bzgl. der OP-Dauer, der Schmerzen, dem DASH-Score und der Zeit bis zur knöchernen Heilung festgestellt werden.
SCHLUSSFOLGERUNG: In der Kurzzeitbeobachtung werden mit Extension-Block-Pinning bessere Ergebnisse in der Behandlung des knöchernen Strecksehnenausriss am Fingerendglied erzielt als mit der Delta-Draht-Technik.
METHODS: An anonymous, voluntary, cross-sectional electronic questionnaire, primarily based on the theory of planned behavior (TPB) was distributed to high school principals and teachers from 20 local (public and private) high schools between October and December 2021. The questionnaire was a 4-part (demographics, willingness, barriers, implementation approach), 23-variable tool.
RESULTS: Eighty-four out of 88 participants were included in the analysis from 20 high schools. The overall willingness to teach CPR to students was 4.2 ± 0.9, and this willingness was significantly associated with being a female (p = 0.019), being a teacher (p = 0.036), having a family history of cardiovascular disease (p = 0.007), previous school CPR campaigns (p = 0.02), and all TPB factors: attitude (p = 0.001), subjective norms (p = 0.011), and perceived behaviour control (p = 0.007). As for perceived barriers, there was moderate concern regarding the absence of the Good Samaritan law (3.8 ± 1.1) and CoVID-19 transmission (3.5 ± 1.3). High school teaching staff recommended formal legislation of CPR training from the Ministry of Education (MoE) and favoured CPR training delivery by healthcare professionals. However, they were willing to conduct CPR training themselves with regular training, material integration into the curriculum, and online teaching material access.
CONCLUSION: High school teachers are willing to teach students CPR. They need MoE legislation, appropriate training, online material, and a standardized database. Teaching staff also recommend specific training session settings. CoVID-19 and Good Samaritan law are moderate barriers. A number of factors influence teaching staff willingness to conduct CPR training. From this analysis, we recommend piloting CPR training in Kuwait high schools with consideration to the identified influential factors and barriers.
OBJECTIVE: This study aimed to describe the usability and utility testing of a newly developed medication adherence app-Med Assist-among ambulatory care patients in Malaysia.
METHODS: The Med Assist app was developed based on the Theory of Planned Behavior and the Nielson usability model. Beta testing was conducted from March to May 2016 at a primary care clinic in Kuala Lumpur. Ambulatory care patients who scored ≥40% on the electronic health literacy scale, were aged ≥21 years, and were taking two or more long-term medications were recruited. Two rounds of in-depth interviews were conducted with each participant. The first interview, which was conducted upon participant recruitment, was to assess the usability of Med Assist. Participants were asked to download Med Assist on their phone and perform two tasks (register themselves on Med Assist and enter at least one medication). Participants were encouraged to "concurrently think aloud" when using Med Assist, while nonverbal cues were observed and recorded. The participants were then invited for a second interview (conducted ≥7 days after the first interview) to assess the utility of Med Assist after using the app for 1 week. This was done using "retrospective probing" based on a topic guide developed for utilities that could improve medication adherence.
RESULTS: Usability and utility testing was performed for the Med Assist app (version P4). A total of 13 participants were recruited (6 men, 7 women) for beta testing. Three themes emerged from the usability testing, while three themes emerged from the utility testing. From the usability testing, participants found Med Assist easy to use and user friendly, as they were able to complete the tasks given to them. However, the details required when adding a new medication were found to be confusing despite displaying information in a hierarchical order. Participants who were caregivers as well as patients found the multiple-user support and pill buddy utility useful. This suggests that Med Assist may improve the medication adherence of patients on multiple long-term medications.
CONCLUSIONS: The usability and utility testing of Med Assist with end users made the app more patient centered in ambulatory care. From the usability testing, the overall design and layout of Med Assist were simple and user friendly enough for participants to navigate through the app and add a new medication. From the participants' perspectives, Med Assist was a useful and reliable tool with the potential to improve medication adherence. In addition, utilities such as multiple user support and a medication refill reminder encouraged improved medication management.
