The Impact of Comment Style on Learners’ Essay Revisions

This paper investigates how the type of written feedback provided by teachers affects learners’ ability to revise essays. A total of 120 participants participated in two rounds of essay composition and feedback delivery. The findings indicate that learners who receive comments in the form of questions are more prone to make revisions compared to those receiving statements or imperatives. These results hold significant implications for educators and the ways they utilize written feedback to enhance learners’ writing skills.

Acetabular revisions using porous tantalum components: A retrospective study with 5-10 years follow-up

AIM To evaluate the clinical and X-ray results of acetabular components and tantalum augments in prosthetic hip revisions.METHODS Fifty-eight hip prostheses with primary failure of the acetabular component were reviewed with tantalum implants. The clinical records and X-rays of these cases were retrospectively reviewed. Bone defect evaluations were based on preoperative CT scans and classified according to Paprosky criteria of Radiolucent lines and periprosthetic gaps; implant mobilization and osteolysis were evaluated by X-ray. An ad hoc database was created and statistical analyses were performed with SPSS software(IBM SPSS Statistics for Windows, version 23.0). Statistical analyses were carried out using the Student's t test for independent and paired samples. A P value of < 0.05 was considered statistically significant and cumulative survival was calculated by the KaplanMeier method.RESULTS The mean follow-up was 87.6 ± 25.6 mo(range 3-120 mo). 25 cases(43.1%) were classified as minor defects, and 33 cases(56.9%) as major defects. The preoperative HHS rating improved significantly from a mean of 40.7 ± 6.1(range: 29-53) before revision, to a mean of 85.8 ± 6.1(range: 70-94) at the end of the follow-up(Student's t test for paired samples: P < 0.001). Considering HHS only at the end of follow-up, no statistically significant difference was observed between patients with a major or minor defect(Student's t test for independent samples: P > 0.05). Radiolucent lines were found in 4 implants(6.9%). Postoperative acetabular gaps were observed in 5 hips(8.6%). No signs of implant mobilization or areas of periprosthetic osteolysis were found in the x-rays at the final follow-up. Only 3 implants failed: 1 case of infection and 2 cases of instability. Defined as the end-point, cumulative survival at 10 years was 95%(for all reasons) and 100% for aseptic loosening of the acetabular component.CONCLUSION The medium-term use of prosthetic tantalum components in prosthetic hip revisions is safe and effective in a wide variety of acetabular bone defects.

Revising Space Groups from Simulated SHELXfcf Structure Factors. More Examples of Incorrect Space Groups, an Example of a Chemically-Incorrect Structure and the Special Case of Pgl to PRevisions

The structure factors of any crystal structure can be simulated from its atomic coordinates (and temperature factors) in a SHELXL-97 run on a dummy hkl in which only the scale factor is refined. The squares of the structure factors are retrieved from the fcf, and such simulated data are used in the revision of the space groups of several incorrectly-refined crystal structures. Two cases, a P1 to P1 revision and a chemically-incorrect structure that is refined in a correct space group, are discussed.

Long-term results after revisions of failed primary vertical banded gastroplasty

AIM: To compare the results after revision of primary vertical banded gastroplasty(Re-VBG) and conversion to sleeve gastrectomy(cS G) or gastric bypass(cR YGB).METHODS: In this retrospective single-center study, all patients with a failed VBG who underwent revisional surgery were included. Medical charts were reviewed and additional postal questionnaires were sent to update follow-up. Weight loss, postoperative complications and long-term outcome were assessed. RESULTS: A total 152 patients were included in this study, of which 21 underwent Re-VBG, 16 underwent c SG and 115 patients underwent c RYGB. Sixteen patients necessitated a second revisional procedure. No patients were lost-to-follow-up. Two patients deceased during the follow-up period, 23 patients did not return the questionnaire. Main reasons for revision were dysphagia/vomiting, weight regain and insufficient weight loss. Excess weight loss(%EWL) after Re-VBG, cS G and cR YGB was, respectively, 45%, 57% and 72%. Eighteen patients(11.8%) reported postoperative complications and 27% reported long-term complaints. CONCLUSION: In terms of additional weight loss, postoperative complaints and reintervention rate, Rouxen-Y gastric bypass seems feasible as a revision for a failed VBG.

Femoral Head Autograft to the Iliac for Use in Future Revisions of Total Hip Arthroplasty: 15-Year Follow-Up

Introduction: The therapeutic success of total hip arthroplasty (THA) is unquestionable. However, in young patients, it is still a controversial topic, not because of the results obtained, but because of the presumed need for revision of the prosthetics components in the future. Objectives: The present work performs a retrospective study of patients who underwent THA surgery in the past, in which the femoral head was transferred to the iliac for use in future revisions of total hip arthroplasty (autograft), and describes the proposed technique. Methods: The research reviewed 27 patients operated on using the femoral head autograft technique for the ipsilateral iliac in total hip arthroplasty, performed from 1996 to 2005;the study considered medical records, X-rays and CT scan images, and photographs taken at the time of surgery. Results: To date, only two revisions of total hip arthroplasty have been performed, in which the patients have benefited from the technique of autografting of the femoral head. No case evolved with infection or any other type of complication. All inserted grafts are consolidated and integrated with the iliac. Conclusion: The autograft technique is cheap, simple and reproducible, making available large amounts of bone for use in future revisions of total hip arthroplasty in young patients.

Analysis of the causes of primary revision after unicompartmental knee arthroplasty: A case series

BACKGROUND Unicompartmental knee arthroplasty(UKA)has great advantages in the treatment of unicompartmental knee osteoarthritis,but its revision rate is higher than that of total knee arthroplasty.AIM To summarize and analyse the causes of revision after UKA.METHODS This is a retrospective case series study in which the reasons for the first revision after UKA are summarized.We analysed the clinical symptoms,medical histories,laboratory test results,imaging examination results and treatment processes of the patients who underwent revision and summarized the reasons for primary revision after UKA.RESULTS A total of 13 patients,including 3 males and 10 females,underwent revision surgery after UKA.The average age of the included patients was 67.62 years.The prosthesis was used for 3 d to 72 months.The main reasons for revision after UKA were improper suturing of the surgical opening(1 patient),osteophytes(2 patients),intra-articular loose bodies(2 patients),tibial prosthesis loosening(2 patients),rheumatoid arthritis(1 patient),gasket dislocation(3 patients),anterior cruciate ligament injury(1 patient),and medial collateral ligament injury with residual bone cement(1 patient).CONCLUSION The causes of primary revision after UKA were gasket dislocation,osteophytes,intra-articular loose bodies and tibial prosthesis loosening.Avoidance of these factors may greatly reduce the rate of revision after UKA,improve patient satisfaction and reduce medical burden.

The Extended Hybrid Carrier-Based Multiple Access Technology for High Mobility Scenarios

The hybrid carrier(HC)system rooted in the carrier fusion concept is gradually garnering attention.In this paper,we study the extended hybrid carrier(EHC)multiple access scheme to ensure reliable wireless communication.By employing the EHC modulation,a power layered multiplexing framework is realized,which exhibits enhanced interference suppression capability owing to the more uniform energy distribution design.The implementation method and advantage mechanism are explicated respectively for the uplink and downlink,and the performance analysis under varying channel conditions is provided.In addition,considering the connectivity demand,we explore the non-orthogonal multiple access(NOMA)method of the EHC system and develop the EHC sparse code multiple access scheme.The proposed scheme melds the energy spread superiority of EHC with the access capacity of NOMA,facilitating superior support for massive connectivity in high mobility environments.Simulation results have verified the feasibility and advantages of the proposed scheme.Compared with existing HC multiple access schemes,the proposed scheme exhibits robust bit error rate performance and can better guarantee multiple access performance in complex scenarios of nextgeneration communications.

Highly Aromatic Norditerpenoid Heterodimers and Monomers from Trigonostemon fragilis

Four new norditerpenoid heterodimers with different dimerization patterns-namely,trigofragiloids A-C(denoted as compounds 1-3)and(+)-and(-)-trigofragiloid D(compound 4)-and three new phenanthrenone norditerpenoids-namely,trigofragiloids E-G(compounds 5-7)-were isolated from Trigonostemon fragilis.Compounds 1 and 2 feature a novel heterodimeric carbon skeleton formed by the conjugation of a tetra-norditerpenoid and an ennea-norditerpenoid;they have been identified as class 2 atropisomers by means of quantum chemical calculations.Compound 3 is an unprecedented phenylpropanoid-norditerpenoid adduct with a new dimerization pattern.Compounds(+)-and(-)-4 are the first example of S-shaped 1,4-dioxane-fused norditerpenoid dimers.Inspired by the structure elucidation of compound 4,two co-occurring analogues,actephilol A and epiactephilol A,were structurally revised as a pair of geometrical isomers and were identified as two pairs of enantiomers,(+)-and(-)-8 and(+)-and(-)-9,respectively.Their structures were characterized using a combined method.Notably,compound 7 exhibits remarkable adenosine triphosphate-citrate lyase(ACLY)inhibition with a halfmaximal inhibition concentration(IC50)value of(0.46±0.11)lmol·L^(-1),as active as the positive control BMS-303141,and a molecular docking study offers deep insight into the interaction between compound 7 and ACLY.
