Authors: Sweity Samaher , Finlay Andrew , Lees Charlotte , Monk Adam , Sherpa Toshi , Wade Derick 
Published: October 2018

Objective: To determine the short-term effects of supplying hospital inpatients with earplugs and eye masks, preparatory to a full-scale trial. Design: A single-centre, open-label, two-arm, parallel group, randomized-controlled trial. Setting: A total of 13 medical and surgical wards in a large teaching hospital in the United Kingdom. Participants: Everyone admitted to hospital aged 18 years or older, who stayed overnight and had the mental capacity and sufficient understanding of English to give consent, the ability to complete the study questionnaire and the ability to use earplugs and eye masks unaided was considered. Interventions: The intervention group was provided with earplugs and eye masks for use the following night, and the control group received standard care. Main measures: Sleep quality assessed using the SleepSure questionnaire after the first night of using the intervention, use of earplugs and eye masks, number of falls throughout their inpatient stay, use of zopiclone during inpatient stay, length of stay and recruitment rate. Results: A total of 1600 patients were admitted; out of which, 626 (39%) were eligible and 206 (13% total, 33% eligible) recruited (intervention group, 109). The intervention group’s mean sleep quality score was 6.33 (95% confidence interval (CI): 5.89–6.77), compared with 5.09 (95% CI: 4.66–5.52) in the control group ( p < 0.001). There were no differences in use of zopiclone, falls or length of stay between the groups. Of the intervention group, 91 (86%) reported using the earplugs and/or eye masks. Conclusions: The intervention seems feasible, and effective, but trial eligibility rate and rate of recruitment into the study were limited.

Published: October 2018

Background: Schizophrenia is a severe, persistent mental disorder, and a leading cause of disability worldwide. Cognitive impairments presented in schizophrenia lead to a worse prognostic, thus treatments targeted to enhance cognition in schizophrenia may be clinically relevant. Aims: The purpose of this study was to assess the efficacy of acetylcholinesterase inhibitors as add-on medication to antipsychotics on cognition in patients with schizophrenia. Methods: Search strategies were developed for Medline, Embase and Cochrane Central Register of Controlled Trials, and are current to March 2018. We included randomised controlled trials that compared antipsychotics plus acetylcholinesterase inhibitors versus antipsychotics plus placebo on prespecified cognitive domains (speed of processing, attention and working memory). Two review authors independently evaluated study eligibility, extracted data and assessed the risk of bias of included studies. We used random-effects model for meta-analyses and assessed the quality of evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Results: We included nine randomised controlled trials. Six randomised controlled trials ( n=219) presented evidence that acetylcholinesterase inhibitors improve speed of processing (standardised mean difference −0.52, 95% confidence interval (−0.79 to −0.25); p value=0.0002). However, eight randomised controlled trials ( n=252) did find placebo was better than acetylcholinesterase inhibitors in the attention domain (−0.43, (−0.72 to −0.13); p value=0.005) and eight randomised controlled trials ( n=273) did not find differences in the working memory (−0.14, (−0.51 to 0.24), p value=0.47). Conclusions: The current evidence is too weak to base recommendations on the use of acetylcholinesterase inhibitors as adjunctive treatments to antipsychotics to improve basic cognitive functions. We have limited confidence in the effect estimates.

Published: October 2018

Background The performance of magnetic resonance imaging (MRI) interpretation and communication of findings and its implication on treatment decisions has not fully been explored in rectal cancer. Purpose To investigate in a region the adherence to MRI protocol standards and the relation between MRI interpretation and selection to preoperative therapy in rectal cancer. Material and Methods Data on consecutive patients who underwent elective rectal cancer surgery in the region from January to June 2010 were obtained from the National Colorectal Cancer Registry. Pretherapeutic MRI images were re-evaluated. Agreement between the original reports and the re-evaluation was compared using Cohen’s kappa coefficient. Results Among the 94 patients included, 81 (86%) had pretherapeutic MRI in accordance with defined imaging guidelines. In 34% of the original MR reports, data on extramural venous invasion (mrEMVI) and mrT category were not reported. Complete tumor staging was not possible because of missing data in 33 (35%) of the patients. The agreement between the original MR reports and the re-evaluation regarding tumor stage was moderate (κ = 0.48). For decided treatment compared to recommended preoperative treatment according to the re-evaluation, the agreement was fair (κ = 0.33). Conclusion Established MRI protocol standards were not universally applied. Missing data and inadequacies in original MRI reports resulted in moderate agreement between the original report and the re-evaluation indicating a risk of inappropriate treatment selection. The results call for further educational efforts in rectal cancer MRI acquisition and repeated audits of image protocol adherence and interpretation quality.

Aims and background Although initial treatment of Hodgkin's disease induces a complete remission in most patients, approximately 50% of patients with advanced disease will not achieve a complete remission or will relapse following the first complete remission. Patients and methods Twenty-three patients with relapsed/resistant Hodgkin's disease, observed between January 1991 and October 1993, underwent CEP combination chemotherapy (CCNU, etoposide, prednimustine). All patients had previously received MOPP and ABVD regimens, in combination at diagnosis or sequentially (at diagnosis and at the first relapse). Results Thirteen (56%) patients achieved complete responses and 4 (18%) had partial responses. Two partial responders obtained a complete remission after a successive autologous bone marrow transplantation. The complete remission was not influenced by the timing of MOPP and ABVD treatments, presence of extranodal involvement or presence of bulky disease, but was affected by the presence of a primary disease refractory to the first standard programs. All the complete responders but 2 were alive and relapse-free at a median follow-up of 15 months; no major toxic effects were recorded. Conclusions These data suggest, as did those of other studies, that CEP is an effective regimen in patients with Hodgkin's disease in first or second relapse, also to reduce the tumor burden and to determine chemosensitivity before contingent bone marrow or peripheral blood stem cell support.

Published: October 2018

Aims and background Many lung cancers are diagnosed in patients over 65 years of age, but limited data are available on the tolerance and activity in elderly patients of chemotherapy protocols designed for adults. Methods We therefore activated a phase II study in patients aged 65 years or older affected by stage IIIB-IV non-small-cell lung cancer in order to assess the tolerance and activity of vinorelbine administered weekly at a dose of 25 mg/m2. Results Since June 1992, 25 patients (20 males, 5 females; performance status ECOG, 0-2) have been included in the study and are evaluable for response and side effects. Two-hundred and twenty-eight cycles of therapy have been delivered (median/patient, 9 cycles). Four partial remissions (16%; 95% confidence interval 5–36%), 9 disease stabilizations, and 12 progressions have been observed. Median time to disease progression was 3 months, and median survival was 5 months (range, 2–25+). Mild or moderate side effects included leukopenia (6 cases), neutropenia (4 cases), anemia (4 cases), nausea (4 cases), infection (3 cases) and thoracic pain (2 cases). Grade III/IV toxicity consisted mainly of leukopenia and neutropenia observed respectively in 5 and in 7 patients. No significant difference in terms of tolerability has been observed for patients aged 65 to 70 with respect to patients aged 70 years or older. Conclusions The administration of vinorelbine in elderly patients does not seem to differ significantly in terms of response and tolerability from that recorded for adults. Selected elderly patients with good performance status and adequate organ function can be safely treated with systemic chemotherapy.

Published: October 2018

Background Metastatic renal cell carcinoma is a “capricious” tumor. Many prognostic factors have been evaluated, treatment is still controversial, and results are not coincident. Methods We reviewed 156 patients with metastatic renal cell carcinoma. Survival from the time of diagnosis was the end point of the study. The influence on survival of age, sex, nephrectomy, disease-free interval, performance status, site and number of metastases was analyzed. Univariate and multivariate analysis were done. Survival according to different therapies was also evaluated. Results In our study, no nephrectomy, a disease-free interval < 24 months, > 2 metastatic sites and a performance status > 2 proved to be risk factors. According to the number of risk factors, 3 groups of patients were identified (low, intermediate and high risk). We observed 3 kinds of responses to treatments: 1) in untreated patients (n = 48), median overall survival was 6 months, and the 24-month survival rate was 8%; 2) in patients treated with hormone therapy and/or chemotherapy (n = 73), median overall survival was 13 months, and the 24-month survival rate was 24%; 3) in patients treated with interferon and/or interleukin-2 (n = 35), median overall survival was 16 months and the 24-month survival rate was 34%. Conclusions Our results are only partially in accordance with those observed by other authors. Risk factors and treatment must be determined in more defined and selected studies.
Cloning and Expression of Functional cDNA Genes of a Mouse/Human Chimeric Antibody rcM4
Authors: Boyd Mark , Xiang Jim 
Published: October 2018

Aim The purpose of this study was to clone and express cDNA genes of heavy and light chains of the mouse/human chimeric antibody rcM4, which recognize the sialosyl-Tn epitope of the TAG72 antigen. Methods The cDNA genes of chimeric heavy-chain M4H2 and light-chain M4K4 were cloned from the cDNA library of the ccM4 transfectoma. The M4H2 and M4K4 genes were modified in polymerase chain reaction and ligated into mpSV2neo-EP-PA and mpSV2gpt-EP-PA to form the heavy- and the light-chain expression vectors mpSV2neo-EP-M4H2-PA and mpSV2gpt-EP-M4K4-PA, respectively. These two expression vectors were then co-transfected into the myeloma cell line SP2/0Ag14. Transfectants were selected in media containing G418 and mycophenolic acid. The rcM4 antibody was purified from transfectant culture supernates by protein A affinity chromatography. Results The yield of the recombinant chimeric antibody rcM4 from its culture supernates was 6 μg/ml. We demonstrated that the rcM4 antibody retained its binding reactivity for sialosyl-Tn and that it was able to mediate effective antibody-dependent cellular cytotoxicity to the human ovarian cancer cell line OVCAR 3 in a manner comparable to the original ccM4 antibody. Conclusion The cDNA genes of chimeric heavy-chains (M4H2) and light-chains (M4K4) could be functionally expressed in the SP2/0Ag14 myeloma cell line. They thus have potential utility in the construction of some novel hybrid proteins such as those containing both antitumor immunoglobulins and cytokine molecules for use in cancer immunotherapy.
Influences on uptake of a community occupational therapy intervention for people with dementia and their family carers
Authors: Field Becky , Coates Elizabeth , Mountain Gail 
Published: October 2018

Introduction Health policy promotes living well with dementia. Occupational therapists deliver interventions to support people with dementia and family carers to live well. This study aimed at identifying influences on uptake of a community occupational therapy intervention by people with dementia and carers, as little evidence about this topic exists. Method Seventeen semi-structured, paired interviews with people with dementia and carers were conducted as part of the ‘Valuing Active Life in Dementia’ research programme. A secondary, qualitative analysis of these interviews explored influences on uptake of the intervention. Findings Four main themes were identified: ‘Grabbing at straws and keen to take part’; ‘We’re trying to put a routine in’; ‘We didn’t know what to expect’, and ‘Give it a go’. Factors identified as potentially influencing uptake included whether the intervention was perceived as potentially meeting needs for support and activity, and whether participants were struggling to adjust or cope. Conclusion Despite limited expectations or apprehension, uptake of this intervention was demonstrated. Understanding why people with dementia and carers accept intervention offers can inform what occupational therapists provide and how it is offered. Further research is required to determine the occupational therapy interventions people with dementia and carers might find supportive at different stages of the disease trajectory.

Published: October 2018

Background: Previous studies have demonstrated that hip arthroscopy is an effective treatment for symptomatic femoroacetabular impingement (FAI) in professional athletes across a variety of sports. However, the return-to-play rates and postoperative performance of elite basketball players after hip arthroscopy are currently unknown. Purpose: To determine return-to-play rates and postoperative performance among professional basketball athletes after hip arthroscopy. Study Design: Case series; Level of evidence, 3. Methods: Eighteen professional basketball players underwent hip arthroscopy (24 hips) for symptomatic FAI between 2001 and 2016 by a single surgeon. Return to play was defined as competing in a single professional game of equal level after surgery. Data were retrospectively obtained for each player from basketball-reference.com , ESPN.com , eurobasket.com, and individual team websites. Matched controls were selected from the websites to compare performances. Results: The mean age at the time of surgery was 25.6 years, and the mean body mass index was 24.4 kg/m2. All players returned to their previous levels of competition, with a mean number of 4 seasons played after surgery (median, 3; range, 1-12). The mean ± SD time between the date of surgery and return to a professional game was 7.1 ± 4.4 months. There was no change in player efficiency rating when pre- and postinjury performance were compared. When compared with controls, players undergoing surgery also had no significant decline in player efficiency rating. Conclusion: Elite basketball athletes who undergo hip arthroscopy for the treatment of FAI return to their presurgical levels of competition at a high rate. These athletes demonstrate no significant overall decrease in performance upon their return to play.

Published: October 2018

Background: Acetabular cartilage lesions are a known cause of poor outcomes after hip arthroscopy and are seen regularly among adolescents. However, studies identifying preoperative factors predictive of acetabular cartilage lesions have been limited to adult populations. Purpose: To assess clinical and radiographic predictors of acetabular cartilage lesions in a large cohort of adolescents undergoing hip arthroscopy. Study Design: Cohort study (Diagnosis); Level of evidence, 3. Methods: Patients undergoing hip arthroscopy for idiopathic femoroacetabular impingement or acetabular labral tears at a children’s hospital were reviewed. Demographic predictors were analyzed by use of univariate logistic regression with generalized estimating equations. A matched case-control analysis was subsequently performed to identify radiographic predictors of acetabular cartilage lesions through use of univariate and multivariable conditional logistic regression. Results: Four hundred two patients (446 hips) undergoing hip arthroscopy between 2010 and 2015 were analyzed. Median age was 16.7 years (range, 13.6-19.0) and 72% of patients were female. Ninety-five hips (21%) were found to have an acetabular cartilage lesion at the time of arthroscopic surgery. Age (odds ratio [OR], 1.7; 95% CI, 1.4-2.1), male sex (OR, 2.5; 95% CI, 1.7-5.0), and body mass index (OR, 1.07; 95% CI, 1.01-1.14) were found to be predictive of intraoperative acetabular cartilage lesions. In the matched case-control analysis, femoral alpha angle as calculated on a Dunn lateral radiograph was independently predictive of an intraoperative acetabular cartilage lesion (OR, 1.8; 95% CI, 1.2-2.6). Additionally, the presence of a crossover sign was independently associated with a decreased odds of an acetabular cartilage lesion (OR, 0.3; 95% CI, 0.1-0.7). On multivariate analysis, alpha angle (Dunn lateral) (OR, 2.0; 95% CI, 1.3-3.1) and crossover sign (OR, 0.2; 95% CI, 0.1-0.7) remained independently associated with the presence of an acetabular cartilage lesion. The presence of an acetabular labral tear was not predictive of an associated cartilage lesion (OR, 1.17; 95% CI, 0.39-3.47; P = .78). Conclusion: In an adolescent population undergoing hip arthroscopy, older age, male sex, and higher body mass index were predictive of acetabular cartilage lesions. From an imaging standpoint, increased alpha angle increased the likelihood of an acetabular cartilage lesion whereas the presence of a crossover sign decreased this likelihood. Predicting the presence of an acetabular cartilage lesion is important when considering a hip arthroscopy procedure to facilitate preoperative planning and to more accurately set patient expectations.
Aluminium Kinetics during Haemodialysis with the Redy 2000 Sorbsystem
Authors: Curtis J.R. , Sampson B. 
Published: October 2018

Aluminium kinetics of the Redy 2000 Sorbsystem using D3260 cartridges and the latest pre-treatment protocol have been studied in vitro and in vivo. In 7 patients, aluminium kinetics were studied during haemodialysis using the Redy 2000 Sorbysystem, D3260 cartridges, S557 acetate concentrate and Gambro hollow fibre dialyser (cuprophane 120M). The same patients were also studied during conventional haemodialysis using the Gambro AK10 proportionating system with acetate dialysate and Gambro hollow fibre dialyser (cuprophane 120M). There was no significant rise in plasma aluminium concentration during dialysis on the Redy 2000 Sorbsystem. The post-dialysis plasma aluminium concentrations were significantly higher after conventional haemodialysis, however, and the explanation for this is not clear but is not accounted for by differences in the degree of ultrafiltration during the studies. A significant rise in dialysate aluminium concentration was observed after 4 hours of dialysis on the Redy 2000 Sorbsystem. The manufacturer's ammonia test papers appear to be too insensitive as indicators of cartridge exhaustion and dialysate pH may be better. The D3260 cartridges should be used for a maximum of 4 hours only. Further long-term studies of aluminium kinetics using this system are justified.
Le Valvole Congenite Dell'Uretra

Prefazione Un'intensa serie di ricerche, associata all'affinamento dei mezzi tecnici di indagine e terapeutici, hanno dato, in epoca relativamente recente, alla fisiopatologia dell'apparato urinario nell'infanzia un impulso tale da fare assumere a questa disciplina la fisionomia di una branca specialistica quasi “a sè stante”. Ancor oggi l'argomento è oggetto di un fervore di idee e di studi rivolti ai numerosi problemi eziopatogenetici, diagnostici, terapeutici che attendono una soluzione definitiva. Presso la Divisione Urologica dell'Ospedale Civile di Padova, da vari anni la materia in questione è stata oggetto di studi e l'esperienza ricavata ha consentito nel 1959 una relazione al XXXII Congresso della Società Italiana di Urologia, tenuto da Dell'Adami sulle “Alterazioni ostruttive delle vie urinarie nell'infanzia”. Il dott. Pagano con questa monografia sulle valvole congenite dell'uretra porta un nuovo valido contributo alla conoscenza di questa particolare forma di ostruzione delle vie urinarie nell'infanzia, frutto degli studi che egli da anni conduce con particolare interesse su questo argomento cosi poco conosciuto della patologia infantile, specie in campo pediatrico.
