Transradial Amputation With Pedicled Pronator Quadratus Interposition and Advanced Neuroma-Prevention Techniques

Abstract. Background: High school and university teachers need to advise students against attempting suicide, the second leading cause of death among 15–29-year-olds. Aims: To investigate the role of reasoning and emotion in advising against suicide. Method: We conducted a study with 130 students at a university that specializes in teachers' education. Participants sat in front of a camera, videotaping their advising against suicide. Three raters scored their transcribed advice on "wise reasoning" (i.e., expert forms of reasoning: considering a variety of conditions, awareness of the limitation of one's knowledge, taking others' perspectives). Four registered psychologists experienced in suicide prevention techniques rated the transcripts on the potential for suicide prevention. Finally, using the software Facereader 7.1, we analyzed participants' micro-facial expressions during advice-giving. Results: Wiser reasoning and less disgust predicted higher potential for suicide prevention. Moreover, higher potential for suicide prevention was associated with more surprise. Limitations: The actual efficacy of suicide prevention was not assessed. Conclusion: Wise reasoning and counter-stereotypic ideas that trigger surprise probably contribute to the potential for suicide prevention. This advising paradigm may help train teachers in advising students against suicide, measuring wise reasoning, and monitoring a harmful emotional reaction, that is, disgust.

Introduction Triangular fibrocartilage complex (TFCC) injuries are associated with distal radioulnar joint (DRUJ) instability and impaired wrist proprioception. Sensorimotor training of extensor carpi ulnaris (ECU) and pronator quadratus (PQ) can enhance DRUJ stability. With limited evidence on effectiveness of TFCC sensorimotor rehabilitation, this study aimed to evaluate the effects and feasibility of a novel wrist sensorimotor rehabilitation program (WSRP) for TFCC injuries. Methods Patients diagnosed with TFCC injuries were recruited from May 2018 to January 2020 at an outpatient hand clinic in Singapore General Hospital. There are four stages in WSRP: (1) pain control, (2) muscle re-education and joint awareness, (3) neuromuscular rehabilitation, and (4) movement normalization and function. WSRP also incorporated dart throwing motion and proprioceptive neuromuscular facilitation. Outcome measures included grip strength measured with grip dynamometer, numerical pain rating scale, joint position sense (JPS) measurement, weight bearing measured with the ‘push-off’ test, and wrist function reported on the Patient Rated Wrist Hand Evaluation. Results Ten patients completed the WSRP. Mean changes were compared with minimal clinically important differences (MCID) for outcomes. All patients achieved MCID on pain, 70% of patients achieved MCID on grip strength, weight bearing and wrist function. Paired t-tests and Cohen’s D for outcome measures were calculated. There were large effect sizes of 2.47, 1.35, and 2.81 for function, grip strength and pain respectively, and moderate effect sizes of 0.72 and 0.39 for axial loading and JPS respectively. Discussion WSRP presents a potential treatment approach in TFCC rehabilitation. There is a need for future prospective clinical trials with control groups.

Abstract Background Understanding the predictors of vaccination intention among healthcare workers, including students in healthcare professions (SHPs), is crucial for policy making and for the development of evidence-driven training programs. The reasoned action approach (RAA) model includes three components to predict intention: attitude (experiential/instrumental), perceived norm (injunctive/descriptive), and perceived behavioral control (capacity/autonomy). We aimed to investigate the predictors of seasonal Flu vaccination intention among SHPs of the University of Milan. Methods We spread an e-survey to all medical residents and first- and last-year SHPs (medicine, nursery, midwifery, healthcare assistance and prevention techniques). The strength of association between measures of RAA components (as well as sociodemographic data, past vaccination behavior, vaccination knowledge, and perceived vaccination facilitation strategies), and vaccination intention was estimated using uni- and multivariate logistic regression models. Results Among 5743 invited SHPs, 884 participated in the survey and were included in the descriptive analyses (52,3% medical residents, 19,9% medicine, 21,1% nursing, 3,6% healthcare assistance, 2,7% prevention techniques and 0,5% midwifery students). Twenty-nine psycho-attitudinal items with an overall Cronbach alpha >0.7 were included in the analyses. The regression analyses were performed on 751 subjects who filled in completely the survey. Past vaccination behavior, vaccination knowledge, experiential attitudes, and perceived vaccination facilitation strategies were positive predictors of Flu vaccination intention (OR 8.16, 2.42, 1.96 and 1.15 respectively, p < 0.05). Conclusions Our results indicated knowledge, experiential attitudes and facilitation strategies as modifiable predictors of vaccination intention among SHPs. Targeted and lasting interventions are needed in order to pursue a change in the strongest predictor, past vaccination behavior. Key messages Past vaccination is the strongest predictor of vaccination intention among students in healthcare professions. Knowledge, attitudes and perceived facilitators predict vaccine propensity among students in healthcare professions.

Pronator Teres

We simulated pronator teres rerouting using a three-dimensional biomechanical model of the arm. Simulations comprised the evaluation of changes in muscle length and the moment arm of pronator teres with changes in forearm axial rotation and elbow flexion. The rerouting of Pronator Teres was simulated by defining a path for it through the interosseous membrane with re-attachment to its original insertion. However the effect of moving the insertion to new positions, 2 cm below and above, the original position was also assessed. The effect on total internal rotation and external rotation capacity was determined by calculating the potential moments for pronator teres, supinator, pronator quadratus, biceps brachii and brachioradialis. Pronator teres was found to be a weak internal rotator in extreme pronation, but a strong internal rotator in neutral rotation and in supination. After rerouting pronator teres was only a strong external rotator in full pronation and not at other forearm positions, where the effect of rerouting was comparable to a release procedure.
