BACKGROUND: Terrible triad injury is a complex injury of the elbow, involving elbow dislocation with associated fracture of the radial head, avulsion or tear of the lateral ulnar collateral ligament, and fracture of the coronoid. These injuries are commonly managed surgically with fixation or replacement of the radial head and repair of the collateral ligaments with or without fixation of the coronoid. Postoperative mobilization is a significant factor that may affect patient outcomes; however, the optimal postoperative mobilization protocol is unclear. This study aimed to systematically review the available literature regarding postoperative rehabilitation of terrible triad injuries to aid clinical decision making. METHODS: We systematically reviewed the PubMed, Embase, Cochrane, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The inclusion criteria were studies with populations aged ≥16 years with terrible triad injury in which operative treatment was performed, a clear postoperative mobilization protocol was defined, and the Mayo Elbow Performance Score (MEPS) was reported. Secondary outcomes were pain, instability, and range of motion (ROM). Postoperative mobilization was classified as either "early," defined as active ROM commencement before or up to 14 days, or "late," defined as active ROM commencement after 14 days. RESULTS: A total of 119 articles were identified from the initial search, of which 11 (301 patients) were included in the final review. The most common protocols (6 studies) favored early mobilization, whereas 5 studies undertook late mobilization. Meta-regression analysis including mobilization as a covariate showed an estimated mean difference in the pooled mean MEPS between early and late mobilization of 6.1 (95% confidence interval, 0.2-12) with a higher pooled mean MEPS for early mobilization (MEPS, 91.2) than for late mobilization (MEPS, 85; P = .041). Rates of instability reported ranged from 4.5% to 19% (8%-11.5% for early mobilization and 4.5%-19% for late mobilization). CONCLUSION: Our findings suggest that early postoperative mobilization may confer a benefit in terms of functional outcomes following surgical management of terrible triad injuries without appearing to confer an increased instability risk. Further research in the form of randomized controlled trials between early and late mobilization is advised to provide a higher level of evidence.

In both sickle cell disease and malaria, red blood cells (RBCs) are phagocytosed in the spleen, but receptor-ligand pairs mediating uptake have not been identified. Here, we report that patches of high mannose N-glycans (Man5-9GlcNAc2), expressed on diseased or oxidized RBC surfaces, bind the mannose receptor (CD206) on phagocytes to mediate clearance. We find that extravascular hemolysis in sickle cell disease correlates with high mannose glycan levels on RBCs. Furthermore, Plasmodium falciparum-infected RBCs expose surface mannose N-glycans, which occur at significantly higher levels on infected RBCs from sickle cell trait subjects compared to those lacking hemoglobin S. The glycans are associated with high molecular weight complexes and protease-resistant, lower molecular weight fragments containing spectrin. Recognition of surface N-linked high mannose glycans as a response to cellular stress is a molecular mechanism common to both the pathogenesis of sickle cell disease and resistance to severe malaria in sickle cell trait.

BACKGROUND: Caudal epidural injection (CEI) is a commonly used procedure to treat back and leg pain secondary to nerve root irritation, predominantly in the context of spinal canal stenosis. Key to a successful outcome is correct needle placement. Although fluoroscopic guidance confirms accurate needle placement, it does not help in determining the starting point, which can lead to multiple needle insertions. OBJECTIVE: This study aimed to determine the variability in size and position of the sacral hiatus and to identify reproducible surface landmarks to locate its position. METHODS AND STUDY DESIGN: 250 human sacral bones were examined, measuring morphology and structure. Vernier callipers accurate to 0.1 mm were used for measurements. Results were analysed using SPSS statistical software. RESULTS: Two specimens were excluded due to agenesis of the hiatus (0.8%). Of the remaining 248 specimens, it was found that the mean internal diameter of the sacral hiatus was 5.12 mm (SD 1.61). The position of the hiatus was variable but was most commonly found at the level of the fourth sacral vertebrae (62.9%, n = 156). Mean distance between the two superolateral sacral prominences was 64.15 mm (SD 6.5) and between superolateral sacral prominences (left and right) and apex of the hiatus were 63.21 mm (SD 10.9) and 63.34 mm (SD 10.87) respectively. CONCLUSION: Although there is a clear anatomical variance in the position and size of the sacral hiatus, this study suggests that surface anatomy landmarks can be used to form an equilateral triangle of which the inferior apex should correspond to the sacral hiatus. Knowledge of this surface anatomy may assist the correct location of the sacral hiatus and hence subsequently improve the efficacy of CEI.

OBJECTIVE: To analyse how staff in one Scottish hospital respond to anonymised patient feedback posted on the nationally endorsed feedback platform Care Opinion; and to understand staff experiences of, and attitudes towards, engaging with Care Opinion data. METHODS: This was a multi-method study comprising: (a) numerical and thematic analysis of stories posted during a six-month period, using a published framework; (b) thematic analysis of interviews with a range of 10 hospital staff responsible for organisational responses to feedback. RESULTS: Seventy-seven stories were published during the six-month period. All received a response, with a mean response time of 3.9 days. Ninety-six responses were made in total, from 20 staff members. Personalisation and tailoring was mostly assessed as performing well against the published framework. Only two 'changes made' were reported. While staff interviewed were mostly understanding of why patients might prefer giving anonymised feedback, some found it uncomfortable and challenging. Participants described instances where they might seek to de-anonymise the individual, in order to pass on personal thanks to the relevant staff member, or to investigate the issue raised and seek resolution offline. Patients did not always want to identify themselves; this could sometimes lead staff to query the veracity or importance of issues raised. Sometimes staff could identify individuals anyway, including one described as 'our regular person'. CONCLUSIONS: Staff used to engaging directly with patients and families, both clinically and in dealing with feedback, need support in dealing with anonymous feedback, and the uncomfortable situation of unequal power it may create.
