Generic learning skills in academically-at-risk medical students: a development programme bridges the gap.

BACKGROUND: Widening access to medical students from diverse educational backgrounds is a global educational mandate. The impact, on students' generic learning skills profiles, of development programmes designed for students at risk of attrition is unknown. AIMS: This study investigated the impact of a 12-month Intervention Programme (IP) on the generic learning skills profile of academically-at-risk students who, after failing at the end of the first semester, completed the IP before entering the second semester of a conventional medical training programme. METHODS: This prospective study surveyed medical students admitted in 2009 and 2010, on entry and on completion of first year, on their reported practice and confidence in information handling, managing own learning, technical and numeracy, computer, organisational and presentation skills. RESULTS: Of 414 first year students, 80 (19%) entered the IP. Levels of practice and confidence for five of the six skills categories were significantly poorer at entry for IP students compared to conventional stream students. In four categories these differences were no longer statistically significant after students had completed the IP; 62 IP students (77.5%) progressed to second year. CONCLUSIONS: A 12-month development programme, the IP, effectively addressed generic learning skills deficiencies present in academically-at-risk students entering medical school.

Changes in shoulder muscle size and activity following treatment for breast cancer.

BACKGROUND: Morbidity of the shoulder after breast cancer is a well-known phenomenon. MRI studies have shown muscle morbidity in cervical cancer and prostate cancer. In breast cancer clinical observations and patient reports include muscle morbidity in a number of muscles acting at the shoulder. Several of these muscles lie in the field of surgery and radiotherapy. Timed interaction between muscles that stabilise the shoulder and those acting as prime movers is essential to achieve a smooth scapulohumeral rthythm during functional elevation of the arm. METHOD: CROSS-SECTIONAL STUDY: Seventy-four women treated for unilateral carcinoma of the breast were included in the study. All patients filled out the Shoulder Pain and Disability Index (SPADI). EMG activity of four muscles was recorded during scaption on the affected and unaffected side. Muscle cross sectional area and signal intensity was determined from MRI scans. The association between EMG and covariates was determined using multiple linear regression techniques. RESULTS: Three of the 4 muscles on the affected side demonstrated significantly less EMG activity, particularly when lowering the arm. Upper trapezius demonstrated the greatest loss in activity. Decreased activity in both upper trapezius and rhomboid were significantly associated with an increase in SPADI score and increased time since surgery. Pectoralis major and minor were significantly smaller on the affected side. CONCLUSION: Muscles affected in the long term are the muscles associated with pain and disability yet are not in the direct field of surgery or radiotherapy. Primary muscle shortening and secondary loss of muscle activity may be producing a movement disorder similar to the 'Dropped Shoulder Syndrome'. Exercise programmes should aim not only for range of movement but also for posture correction and education of potential long-term effects.

Delayed versus immediate exercises following surgery for breast cancer: a systematic review.

BACKGROUND: Seroma formation, wound healing and fluid drainage are a concern for both surgeons and patients. Excessive fluid production can result in seroma formation, and inadequate drainage of seromas is known to cause infection, pain, discomfort and longer periods of hospitalisation. Postoperative exercises given to maintain movement of the arm are believed to increase the amount of fluid production following surgery. This review aimed to determine whether a program of delayed exercises reduces the risk of seroma formation, fluid loss and hospital stay, without loss of arm movement. METHOD: A systematic review. RCTs of early versus delayed shoulder mobilisation after surgery in females with breast cancer were included in the review. Outcomes. One or more measurements of shoulder range of motion, wound complications, fluid drainage volumes and incidence of seroma formation. Design. Randomised controlled trials, control group of delayed exercise/mobilisation. Validity assessment was carried out using a data extraction form based on the CONSORT statement. Study characteristics recorded include sample size, intervention, control, period of exercise delay, surgical procedure and conclusions drawn. Data synthesis was carried out using random effects and weighted mean differences to test for heterogeneity and combined effects. RESULTS: 12 RCTs were included in the review of which 6 were included for meta-analysis. Delaying exercises significantly decreases seroma formation (OR=0.4; 95%CI 0.2-0.5; p=0.00001). No significant differences were found for drainage volume or hospital stay. CONCLUSION: Current evidence from RCTs supports the use of a delayed program of arm exercises to reduce seroma formation. Clinical and statistical inconsistencies between studies did not allow any conclusions to be drawn regarding the effects of delayed exercises on fluid drainage, hospital stay and immediate or long term ability to move the arm.

Changes in the cross-sectional area of multifidus and psoas in patients with unilateral back pain: the relationship to pain and disability.

STUDY DESIGN: Prospective, cross-sectional observational study. OBJECTIVES: The aim of this study was to determine if there was an association between wasting of psoas and multifidus as observed on MRI scans and the presenting symptoms, reported pathology, pain, or disability of a cohort of patients presenting with unilateral low back pain. SUMMARY OF BACKGROUND DATA: Current physiotherapy practice is often based on localized spine stabilizing muscle exercises; most attention has been focused on transversus abdominus and multifidus with relatively little on psoas. METHOD: Fifty consecutive patients presenting to a back pain triage clinic with unilateral low back pain lasting more than 12 weeks were recruited. The cross-sectional surface area (CSA) of the muscles was measured. Duration of symptoms, rating of pain, self-reported function, and the presence of neural compression were recorded. RESULTS: Data analysis compared the CSA between the symptomatic and asymptomatic sides. There was a statistically significant difference in CSA between the sides (P < 0.001). There was a positive correlation between the percentage decrease in CSA of psoas on the affected side and with the rating of pain (rho = 0.608, P < 0.01), reported nerve root compression (rho = 0.812, P < 0.01), and the duration of symptoms (rho = 0.886, P < 0.01). There was an association between decrease in the CSA of multifidus and duration of symptoms. CONCLUSIONS: Atrophy of multifidus has been used as one of the rationales for spine stabilization exercises. The evidence of coexisting atrophy of psoas and multifidus suggests that a future area for study should be selective exercise training of psoas, which is less commonly used in clinical practice.
