Background: Introduction of new implants should be monitored closely to capture any signs of compromising patient safety. Vitamin E infused highly-crosslinked polyethylene liners (VEPE) offer the potential for reduced wear. Highwall liners have been hypothesised to result in increased wear and potential liner fractures. The aim of this study was to determine the 3–7-year follow-up of highwall VEPE for primary total hip arthroplasty (THA), focusing on liner-related complications. Methods: We included 1221 consecutive THA operations from July 2010 to May 2014 with minimum follow-up of 3 (3.1–6.8) years Data collected included demographics, implant data, complications, reoperations, and deaths. Data were cross-referenced with the Danish Hip Arthroplasty Registry in order to ensure validity and completeness. Acetabular shell position was measured using Martell Hip Analysis Suite in a subgroup of 931 THAs. Results: Cumulative stem revision and shell revision at 3-year follow-up was 3.4% and 0.4% respectively. There were no revisions due to liner failure. Reason for revision included 11 dislocations, 15 soft-tissue revisions for infection, 44 stem revisions of which 34 were periprosthetic fractures and 13 shell revisions of which 6 were combined shell and stem revisions. Conclusion: Early follow-up of VEPE liners for primary THA have not shown any revisions associated with liner failure. Continued monitoring of new materials are necessary to capture any signs of compromised patient safety.

Introduction: Central venous accesses devices (CVADs) have a fundamental importance for diagnostic and therapeutic purposes in pediatric onco-hematological patients. The treatment of pediatric onco-hematological diseases is complex and requires the use of integrated multimodal therapies. Long-lasting and safe central venous access is therefore a cornerstone for any successful treatment. Methods: The aim of this work is to define pediatric guidelines about the management of CVADs in onco-hematology. A panel of experts belonging to the working groups on Infections and Supportive Therapy, Surgery and Nursing of the Italian Pediatric Hematology Oncology Association (AIEOP) revised the scientific literature systematically, scored the level of evidence and prepared these guidelines. The content of the following guidelines was approved by the Scientific Board of AIEOP. Results and Conclusions: Important innovations have been developed recently in the field of CVADs, leading to new insertion methods, new materials and new strategy in the overall management of the device, especially in the adult population. These guidelines recommend how to apply these innovations in the pediatric population, and are directed to all physicians, nurses and health personnel active in the daily management of CVADs. Their aim is to update the knowledge on CVAD and improve the standard of care in pediatric patients with malignancies.

Published: November 2020

Objective:The aim of the work was to demonstrate the effectiveness and safety of ultrasonographic guided aspiration performed with corticosteroid injection intra-lesional for ruptured Baker cysts (BCs).Methods:Single-center retrospective study that included 42 patients with knee joint disorder associated with ruptured BCs were treated by ultrasonographic guided aspiration of fluid from the cyst and different points from the calf then intra-lesional injection of corticosteroids once or twice, 1 week apart. Follow up were done weekly until complete resolution of symptoms. Visual analog scale (VAS) and Rauschning-Lindgren and Lysholm Knee Scoring Scales (RLC) were used for assessment.Results:Clinical parameters (VAS and RLC) improved significantly in all patients at both post injection evaluation visits (1 week and 12 weeks). Ultrasonographic features improved significantly with complete disappearance of free fluid in the calf in 35 (83.3%) cases 1 week after the injection, and in 41 (97.6%) after 12 weeks. As regards BCs only 4 (9.5%) cases showed complete disappearance after 1 week and there was recurrent BCs in 38 (90.5%) cases which required reaspiration. While after 12 weeks, BCs were completely disappeared in 23 (54.8%) cases, most of the relapsed BCs were complex BCs. No side effects were reported in all cases.Conclusion:Ultrasonographic guided aspiration followed by injection of corticosteroids intra-lesional is an efficient and safe method for managing ruptured BCs.
Community-Based Social Marketing in Theory and Practice: Five Case Studies of Water Efficiency Programs in Canada
Authors: Fries Sarah , Cook Julie , Lynes Jennifer Kristin 
Published: November 2020

Background: Community-based social marketing (CBSM) offers a pragmatic five-step approach to developing a program that fosters sustainable behaviour. However, how the CBSM theoretical framework has been implemented into practice remains largely under-evaluated. To help address this gap, Lynes et al. developed 21 benchmarks to assess CBSM programs. This research builds upon these benchmarks by using both the benchmarks and additional assessment criteria to assess five Canadian programs that have used CBSM principles. Focus: This paper is related to research and evaluation of community-based social marketing. Research Question: How has the CBSM theoretical framework been implemented in practice at the community level? Importance to the Social Marketing Field: By exploring how five Canadian programs have implemented CBSM, this paper enables practitioners to align their programs with CBSM principles more closely. It also contributes to the literature on CBSM effectiveness. Methods: Five qualitative case studies were assessed, each featuring a Canadian community program seeking to influence residential water efficiency behaviour. In order to systematically assess each program’s adherence to the CBSM theoretical framework, a CBSM benchmark assessment tool that proposes additional assessment criteria to Lynes et al.’s 21 benchmarks was developed. The assessment tool allowed for replicable benchmark assessments across multiple programs. Triangulation of data from both primary (survey and interview) and secondary (peer-reviewed literature, gray literature, and online reporting) data sources informed the assessment of each case study. Results: On average, over the five case studies, just over half of the 21 benchmark criteria were fully integrated into the programs, whereas just under a third were partially integrated, and approximately one fifth were not integrated at all. Recommendations for Research or Practice: While the benchmarks were fairly well integrated overall, this paper outlines several recommendations that programs may consider to improve alignment with the CBSM theoretical framework and benchmarks. Recommendations for future research to explore CBSM effectiveness are also made. Limitations: Lack of generalizability due to small sample size, unable to make assessments of programmatic success, and inherent limitations of the benchmark assessment tool.

Published: November 2020

Purposes: Minichromosome maintenance (MCM) proteins play an important role in replication and cell cycle progression. Even so, their expression and prognostic roles in cancer remain controversial. Methods: To address this issue, the study investigated the roles of MCMs in the prognosis of GC by using ONCOMINE, GEPIA2, UALCAN, Cancer Cell Line Encyclopedia (CCLE), the Human Protein Atlas, Kaplan-Meier Plotter, cBioPortal, GeneMANIA, and DAVID databases. Results: Over expressions of mRNA and cell lines were found in all members of the MCM family, and MCMs were found to be significantly associated with pathological tumor grades in GC patients. Besides, higher mRNA expressions of MCM1/5/7 were found to be significantly associated with shorter overall survival (OS) and progression-free survival (FP) in GC patients, while higher mRNA expression of MCM4/6/9 were connected with favorable OS and FP. Moreover, a high mutation rate of MCMs (68%) was also observed in GC patients. Conclusions: The results indicated that MCM1/5/7 were potential targets of precision therapy for patients with GC. And MCM4/6/9 were new biomarkers for the prognosis of GC. The results of the study will contribute to supplement the existing knowledge, and help to explore therapeutic targets and enhance the accuracy of prognosis for patients with GC.

Objective To report and analyze the indications and results of endovascular and open surgical treatment for uretero-arterial fistula. Methods We retrospectively reviewed the clinical data of 25 consecutive patients with uretero-arterial fistulas admitted to our hospital from 2011 to 2020. Endpoints were technical success, freedom from open conversion, stent-graft/graft-related complications, and 30-day and one-year mortality. Results The study included 25 patients (68% female, n = 17) with 27 uretero-arterial fistulas by bilateral pathologies in two patients. The mean age was 61 ± 11 years (range 35–80). The most common predisposing factors for uretero-arterial fistula were history of pelvic operations for malignancy in 21 patients (84%), radiotherapy in 21 patients (84%), previous pelvic vascular bypass in 2 patients (8%), and iliac aneurysms in 2 patients (8%). On average, the period between the primary pelvic surgery and the diagnosis of uretero-arterial fistulas was 46 months (range 7–255). Twenty patients (80%) underwent endovascular treatment of the uretero-arterial fistulas. The primary technical success of the endovascular treatment was 95%, and the freedom from open conversion was 40% at six months and 30% at one year. Thirteen uretero-arterial fistulas (48%) underwent delayed open conversion due to recurrent bleeding in six cases (46%), stent-graft infection in three cases (23%), or pelvic abscess in four cases (31%). Primary open surgery was applied for five (20%) patients. After a mean follow-up of 34 months, early (<30 days) mortality was 8% (2/25), one-year mortality 16% (4/25), and overall mortality was 24% (6/25). Conclusions Uretero-arterial fistula is a late complication of prior pelvic surgery, radiation, and indwelling ureteral stents. Endovascular treatment remains an effective and less invasive modality in controlling the related life-threatening arterial bleeding of the uretero-arterial fistula. Open surgical treatment is still required for patients with local sepsis, previously failed endovascular treatment or infected stent-grafts.

Published: November 2020

Background Beat-to-beat blood pressure variability is associated with increased stroke risk but its importance at different ages is unclear. Aims To determine the age-sex distribution of blood pressure variability in patients with transient ischemic stroke or minor stroke. Methods In consecutive patients within six weeks of transient ischemic stroke or non-disabling stroke (Oxford Vascular Study), non-invasive blood pressure was measured beat-to-beat over five minutes (Finometer). The age-sex distribution of blood pressure variability (residual coefficient of variation) was determined for systolic blood pressure and diastolic blood pressure. The risk of top-decile blood pressure variability was estimated (logistic regression), unadjusted, and adjusted for age, sex, and cardiovascular risk factors. Results In 908 of 1013 patients, excluding 54 in atrial fibrillation and 51 with low quality recordings, residual coefficient of variation was positively skewed with a median systolic residual coefficient of variation of 4.2% (IQR 3.2–5.5) and diastolic residual coefficient of variation of 3.9% (3.0–5.5), with 90th centile thresholds of 7.2 and 7.3%. Median systolic residual coefficient of variation was higher in patients under 50 years (4.5 and 3.0–5.3) compared to 60–70 years (4.1 and 3.2–5.2), but rose to 4.5% (3.5–6.9) above 80 years, with an increasingly positive skew. The proportion of patients with markedly elevated blood pressure variability in the top-decile increased significantly per decade (OR 1.72, p < 0.001), after adjustment for sex and risk factors. Conclusions Median beat-to-beat blood pressure variability fell in midlife, reflecting loss of physiological, organized blood pressure variability. However, rates of markedly elevated blood pressure variability significantly increased with greater age, suggesting that blood pressure variability may be particularly important in older patients.

Published: November 2020

Aims: Interstitial lung disease (ILD) is associated with the incidence of non-small cell lung cancer (NSCLC). Patients with ILD are at risk of acute exacerbation (AE) after pulmonary resection. However, there have been no recognized treatment guidelines for NSCLC patients with ILD on computed tomography (CT). Methods: We reviewed the medical records of 156 consecutive patients with ILD on high-resolution CT who have undergone pulmonary resection and between 2014 and 2018. Data regarding general information, imaging features, perioperative indicators, and long-term prognosis of patients were compared. Results: The mean patient age was 67.24 ± 6.80 years. Postoperative AE occurred in seven (4.5%) patients; five (71.4%) of the seven patients who had an AE died within 30 days. The incidence of postoperative AE was 5.3% among patients who underwent lobectomy ( n = 6). Overall survivals (OS) was significantly poorer in patients with possible usual interstitial pneumonia (UIP)/UIP [hazard ratio (HR) 2.34, 95% confidence interval (CI) 1.11–4.95, p = 0.026] and severe postoperative complications (Grade ⩾3) ( versus no complication: HR 2.58, 95% CI 1.11–6.02, p = 0.028; versus mild complications: HR 6.05, 95% CI 2.69–13.6, p < 0.001). Age (HR 1.071, 95% CI 1.006–1.137, p = 0.030) and ILD patterns (HR 2.420, 95% CI 1.024–5.716, p = 0.044) were independent prognostic factors for OS. Forced vital capacity (FVC) (odds ratio 0.351, 95% CI 0.145–0.850, p = 0.020) was an independent prognostic factor for patients who needed postoperative intensive care unit intervention. Conclusion: Pulmonary resection for NSCLC Patients with ILD on CT is a safe procedure. However, surgical indications for lobectomy need to be more carefully for these patients, especially for possible UIP/UIP patients and patients with lower FVC.

Published: November 2020

Background: There are two US Food and Drug Administration (FDA)-approved drugs, pirfenidone and nintedanib, for treatment of patients with idiopathic pulmonary fibrosis (IPF). However, neither of these drugs provide a cure. In addition, both are associated with several drug-related adverse events. Hence, the pursuit for newer IPF therapeutics continues. Recent studies show that joint analysis of systems-biology-level information with drug–disease connectivity are effective in discovery of biologically relevant candidate therapeutics. Methods: Publicly available gene expression signatures from patients with IPF were used to query a large-scale perturbagen signature library to discover compounds that can potentially reverse dysregulated gene expression in IPF. Two methods were used to calculate IPF–compound connectivity: gene expression-based connectivity and feature-based connectivity. Identified compounds were further prioritized if their shared mechanism(s) of action were IPF-related. Results: We found 77 compounds as potential candidate therapeutics for IPF. Of these, 39 compounds are either FDA-approved for other diseases or are currently in phase II/III clinical trials suggesting their repurposing potential for IPF. Among these compounds are multiple receptor kinase inhibitors (e.g. nintedanib, currently approved for IPF, and sunitinib), aurora kinase inhibitor (barasertib), epidermal growth factor receptor inhibitors (erlotinib, gefitinib), calcium channel blocker (verapamil), phosphodiesterase inhibitors (roflumilast, sildenafil), PPAR agonists (pioglitazone), histone deacetylase inhibitors (entinostat), and opioid receptor antagonists (nalbuphine). As a proof of concept, we performed in vitro validations with verapamil using lung fibroblasts from IPF and show its potential benefits in pulmonary fibrosis. Conclusions: As about half of the candidates discovered in this study are either FDA-approved or are currently in clinical trials for other diseases, rapid translation of these compounds as potential IPF therapeutics is possible. Further, the integrative connectivity analysis framework in this study can be adapted in early phase drug discovery for other common and rare diseases with transcriptomic profiles.

Published: November 2020

We report the case of a healthcare worker who presented with a large vessel acute ischemic stroke in setting of a mild SARS-CoV-2 infection and provide a review of the emerging literature on COVID-related stroke. A 43-year-old female presented with right-sided hemiparesis, aphasia and dysarthria. She had a nonproductive of cough for 1 week without fever, fatigue or dyspnea. A CT Head, CT angiography and CT perfusion imaging revealed a M1 segment occlusion of the left middle cerebral artery requiring transfer from a primary to a comprehensive stroke center. A nasopharyngeal swab confirmed SARS-CoV-2 infection prior to arrival at the accepting center. During the thrombectomy a 3 cm thrombus was removed. Thrombus was also evident in the 8 French short sheath during closure device placement so a hypercoagulable state was suspected. Stroke work-up revealed a glycosylated hemoglobin of 8.7%, elevation of inflammatory markers and an indeterminate level of lupus anticoagulant IgM. On discharge home, she had near complete neurological recovery. This case highlights suspected mechanisms of hypercoagulability in SARS-CoV-2 infection and the importance of optimizing stroke care systems during the COVID-19 pandemic.

Published: November 2020

Objectives: The aim of this study was to determine the proportion and mechanism of resistance to ceftriaxone and ceftazidime among Klebsiella species and Escherichia coli and examine the burden of methicillin-resistant Staphylococcus aureus from caesarean section surgical site infections in Uganda. Methods: Wound swabs from 109 caesarean section surgical site infections were cultured for pathogenic bacteria following standard microbiological procedures. The Kirby–Bauer disc diffusion technique was used for antimicrobial susceptibility testing. Methicillin-resistant S. aureus diagnosis was based on polymerase chain reaction testing for the mecA gene. Data were analysed using SPSS-IBM Statistics v.20. Results: A total of 118 pathogens were recovered from 93 (85%) of 109 surgical site infections swabs. Of the 118 pathogens, gram-negative bacteria were 69 (58.5%), including 44 (37.3%) Klebsiella species, 11 (9.3%) E. coli, 6 (5.1%) Citrobacter species, and 8 (6.8%) other gram-negative bacteria. In total, 49 of the 118 pathogens were gram-positive bacteria, including 34 (28.8%) S. aureus and 15 (12.7%) Enterococci species. Resistance to ceftriaxone was detected in all 11 (100%) of the E. coli and in 43 (97.7%) of the 44 Klebsiella species and to ceftazidime in all 11 (100%) of the E. coli and 40 (91%) of the 44 Klebsiella species. Extended-spectrum beta-lactamase explained resistance to ceftazidime in 10 (91%) of the 11 E. coli and 19 (48%) of the 40 Klebsiella species. Carbapenemase production explained 15 (38%) of the 40 ceftazidime-resistant Klebsiella species. Methicillin-resistant S. aureus was detected in 91% of S. aureus. Conclusion: Klebsiella species, E. coli, and S. aureus–majority methicillin-resistant S. aureus dominated the pathogens in caesarean section surgical site infections. Almost all of the E. coli and Klebsiella species were resistant to ceftriaxone or ceftazidime. Extended-spectrum beta-lactamase was the underlying resistance mechanism among almost all of the ceftriaxone- or ceftazidime-resistant E. coli. However, this mechanism accounted for less than half of ceftriaxone- or ceftazidime-resistant Klebsiella species, where carbapenemases accounted for 40% of the resistance, a finding previously unreported in Uganda.
