Introduction: Cementless fixation is the standard for acetabular fixation in primary total hip arthroplasty (THA). There are various surface finishes thought to improve osteointegration, although literature regarding the long-term survival of some of these surfaces is limited. Regardless of design, primary stability is essential to allow for osteointegration. Previous studies have suggested an increased rate of radiolucency and compromised short-term functional outcomes using the Tritanium primary acetabular component (Stryker, Mahwah, NJ). The purpose of this study was to compare the primary Tritanium acetabular component to another contemporary acetabular component as a control group with an established clinical record. Methods: 444 consecutive, primary THAs performed by a single surgeon from 2008 to 2012 were reviewed. Patients were included if they had a minimum 1-year follow-up. Implant survivorship and modified Harris Hip Scores (mHHS) were recorded for all patients at final follow-up. Radiographs were evaluated by 2 surgeons at 6 weeks, 1 year, and the most recent follow-up for evidence of radiolucency and migration. Components were considered to have evidence of radiographic lucency if they had radiolucency in 2 or more DeLee zones. Results: 198 patients met criteria for inclusion (96 Pinnacle, 102 Tritanium). Average follow-up was 28 (12–72) months. At final follow-up 6.2% of the Pinnacle cups and 29.4% of the Tritanium cups had radiographic evidence of loosening ( p < 0.01). The average mHHS for the Tritanium group was 83.1, and 88.4 for the Pinnacle group ( p < 0.01). Radiographic evidence of loosening also correlated with a lower mHHS: 75.5 versus 86.4 ( p < 0.01). In patients that received Tritanium cups without screw fixation 44.6% showed radiographic evidence of loosening versus 8% that received screw fixation ( p < 0.01). In total, 6 patients in the Tritanium group required revision for aseptic loosening of the acetabular component. Conclusions: The 30% rate of radiographic loosening in the Tritanium group was significantly higher than the Pinnacle group and correlated with an inferior clinical outcome. Interestingly the use of screw augmentation was protective against radiographic evidence of loosening. This suggests that the Tritanium component may be prone to fibrous in-growth because of inadequate primary stability.

ObjectivesTo prospectively investigate differences in medium-term patient-reported outcome measures and objective functional outcome measures, between patients receiving and those not receiving intensive short-term immunosuppressive therapy for coronavirus disease 19 (COVID-19)-associated hyperinflammation.MethodsPatients previously included in the COVID-19 High-intensity Immunosuppression in Cytokine storm syndrome (CHIC) study who received immunosuppressive treatment versus standard of care for COVID-19-associated hyperinflammation were invited for follow-up at 3 and 6 months after hospitalisation. At both visits, patients were assessed by a pulmonologist, completed quality of life (QoL) questionnaires and performed pulmonary and exercise function tests. At 3 months, patients additionally completed questionnaires on dyspnoea, anxiety, depression and trauma. Outcomes were compared between patients receiving and those not receiving intensive short-term immunosuppressive therapy for COVID-19-associated hyperinflammation.Results131 (66.5%) patients survived hospitalisation due to COVID-19-associated hyperinflammation and 118 (90.1%) were included. QoL questionnaires, pulmonary- and exercise function tests showed improvement between 3 and 6 months after discharge, which was similar in both groups. Assessed patients reached levels that were close to levels predicted from the normal population. In contrast, diffusing capacity of the lung for carbon monoxide was disturbed in both groups: 69.6% predicted (SD 16.2) and 73.5% predicted (SD 16.5) in control group and treated group, respectively.ConclusionsNo differences in medium-term outcomes are demonstrated in survivors of COVID-19-associated hyperinflammation treated or not treated with methylprednisolone with or without tocilizumab during the acute phase. Short-term benefits of this therapy, as showed in the baseline CHIC study analysis, are thus not hampered by medium-term adverse events.

Zero Fluoroscopy

Introduction: Radiofrequency catheter ablation of atrial fibrillation is performed under fluoroscopic guidance and therefore carries radiation risk exposure for the both the patient and the operator. Three-dimensional mapping systems and newer technologies to allow non-fluoroscopic catheter visualization together with intracardiac echo have reduced but not abolished the fluoroscopy exposure. We aim to demonstrate the feasibility, the safety and the efficacy of catheter ablation for atrial fibrillation without the use of fluoroscopy. Methods: A totally fluoro-less approach was developed for AF ablation at our Institution. 94 consecutive AF patients underwent zero fluoroscopy catheter ablation for atrial fibrillation. In the zero fluoroscopy cases, the fluoroscopy arm was kept far away from the patient table. Access including double trans-septal, mapping with the Carto 3 system and ablation were all performed without fluoroscopy with the use of ICE and the Carto 3 system. These 94 patients were compared with 94 control patients matched for age, sex and type of AF who underwent AF ablation by the same operator with the use of fluoroscopy. Results: Baseline characteristics were similar between fluoroless (N=94, Age=64.5 ± 10.1, 75.5% male, 48% paroxysmal) and control (N=94, Age=65.1 ± 9.9, 72.3% male, 50% paroxysmal) group. Non-PV triggers were detected and ablated in 51 (54.3%) and 56 (59.6%) patients in fluoroless and control group respectively (p=0.5). Average fluoro time in control group was 10.1 ± 4.7 minutes. Procedure duration was comparable (120.4 ± 25.8 vs. 122.2 ± 28.7, p =0.6). After the short term median follow-up of 4.5 (4 – 6.5) months, 10 (10.6 %) patients in flourless and 9 (9.6%) patients in control group experienced recurrences (p=0.8).One pericardial effusion requiring pericardiocenteis occurred in the fluoroless group. Conclusions: Our series show that zero fluoroscopy ablation of atrial fibrillation with the use of newer technologies is feasible, safe and efficacious at the short term follow up. Importantly in our series the double transeptal was performed without fluoroscopy and the ablation was not limited to the pulmonary veins only but included ablation of the posterior wall, the coronary sinus and the left atrial appendage.

ObjectiveEndoscopic suture gastroplasty (ESG) has been developed as an alternative treatment for moderately obese patients. We present our results of a short-term randomised controlled trial on a new suturing technique, the Endomina system (E-ESG, Endo Tools therapeutics, Belgium).DesignEligible patients (body mass index 30–40 kg/m2) were randomised in a 2:1 ratio to receive lifestyle modification plus E-ESG or lifestyle modification alone (control group); dietetic counselling and follow-up were identical. Endpoints included a mean excess weight loss (EWL) of more than 25% 12 months after E-ESG and a 15% EWL difference at 6 months between groups. At 6 months, a cross-over to E-ESG was offered to the control group. All patients were followed for a total of 12 months after E-ESG.ResultsOf the 71 patients included (five male, mean age 40 years), mean EWL at 6 months was significantly higher in the treatment (38.6%, n=45) than in the control group (13.4%, n=21; p<0.001). At 6 months, satiety tests demonstrated a higher decrease in mean volume (41% vs 2.5%, p<0.001), and mean quality of life (QoL) was also higher in the treatment group (52.8 vs 45.1 p<0.05). No procedure-related or device-related severe adverse events were observed. Twelve months follow-up after E-ESG showed a mean EWL of 45.1%, which translated into a total body weight loss of 11.8%.ConclusionsThis study demonstrates that E-ESG is safe and effective, providing a 25% better EWL at 6 months than lifestyle modification alone. This weight loss was maintained and resulted in a significant improvement in QoL up to 18 months after treatment.Trial registration numberNCT03255005.

Bone marrow stromal cells (BMSCs) may differentiate into nerve cells under a certain condition; however, the clinical application for treating nervous system disease remains unclear. The aim is to assess the safety profile, feasibility, and effectiveness of surgery combined with autologous BMSCs transplantation for treating ICH. 206 ICH patients who had received surgical procedure were divided into transplantation (n=110) or control group (n=96). For transplantation group, BMSCs were injected into the perihemorrhage area in the base ganglia through an intracranial drainage tube 5.5 (3.01–6.89) days after surgery, followed by a second injection into the subarachnoid space through lumbar puncture 4 weeks later. Neurologic impairment and daily activities were assessed with National Institute Stroke Scale (NIHSS), Barthel index, and Rankin scale before transplantation and 6 months and 12 months after transplantation. Our results revealed that, compared with control group, NIHSS score and Rankin scale were both significantly decreased but Barthel index was increased in transplantation group after 6 months. Interestingly, no significant difference was observed between 12 months and 6 months. No transplantation-related adverse effects were investigated during follow-up assessments. Our findings suggest that surgery combined with autologous BMSCs transplantation is safe for treatment of ICH, providing short-term therapeutic benefits.

We investigate the clinical and pathological features related to variations in colorectal tumour apoptosis, proliferation and angiogenesis and the influence of the latter in short-term mortality (2 years); 551 tumour samples from a prospective cohort of patients with colorectal cancer were examined and tumour biology markers were determined as follows: percentage of apoptotic cells, by the terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling technique; Ki-67 antigen, as a cell proliferation marker and density of microvessels (as a marker of angiogenesis). An increase in the percentage of cellular apoptosis is significantly related to the presence of poorly differentiated tumours, with vascular invasion (p < 0.001). The CD105 angiogenesis marker is not related to any clinical–pathological parameter except that of higher frequency in older patients (p = 0.03). Ki-67 is more frequently expressed in tumours with less nervous invasion (p = 0.05). Neither apoptosis nor angiogenesis present any significant association with short-term survival. The only marker clearly related to 2-year survival is Ki-67, which is shown to be a good prognostic factor in the multivariate analysis (hazard ratio = 0.49; 95% confidence interval = 0.27–0.90). Therefore, in a prospective cohort of colorectal cancer patients, only Ki-67 is a marker of good prognosis in short-term follow-up.

AbstractThe Emotion Focused Training for Self-Compassion and Self-Protection (EFT-SCP) is an intervention developed to increase skills of self-compassion and protective anger with the aim to decrease self-criticism. This novel intervention was developed on the basis of the latest findings on self-criticism from Emotion-focused therapy and previous programs cultivating compassion (namely Compassion Mind Training and Mindful Self-Compassion Program). According to existing research, simply cultivating self-compassion is not always sufficient in reducing self-criticism. Therefore, the EFT-SCP was designed to build self-compassion whilst developing protective anger to combat self-criticism. Our goal was to investigate the efficacy of this new, short-term, online EFT-SCP program in a non-clinical population. A randomized control trial was conducted with pre- and post-intervention measurements and two-month follow-up of self-compassion and self-criticism/reassurance. Convenience sampling was used to recruit participants through a snowballing technique on social media. A total of 123 participants were randomly allocated to the EFT-SCP intervention or to a control condition. The intervention group were instructed through emails to complete an EFT-SCP task every day for 14 consecutive days. The control group did not complete any tasks. Out of 123 participants, 31 from intervention group and 20 from control group completed all measurements. There was a significant effect of the EFT-SCP on increasing self-compassion and self-reassurance scores as reported at two-month follow-up. The EFT-SCP was also effective at reducing self-uncompassionate responding and self-criticism (specifically Hated self) with changes evident at two months post-intervention. These findings are encouraging and suggest that interventions designed to enhance self-compassion and decrease self-criticism can be delivered to broader populations without the direct contact with mental health professionals.

BACKGROUND Shift work can be demanding owing to disturbances in the biological and social rhythms. This can cause short-term negative effects in employees, such as increased fatigue and reduced alertness. A potential way to counteract these negative effects is to enhance employees’ recovery from work during working hours. OBJECTIVE The aim of this study is to develop and implement an intervention that focuses on promoting “on-job” recovery of shift workers. METHODS This study is performed in 2 department units with shift workers at a multinational company in the steel industry. For each department, an intervention will be developed and implemented through an iterative process of user-centered design and evaluation. This approach consists of various sessions in which employees and a project group (ie, researchers, line managers, human resource managers, and occupational health experts) provide input on the intervention content and implementation. Intervention effects will be evaluated using pretest and posttest web-based surveys. Digital ecological momentary assessment will be performed to gain insight into the link between the intervention and daily within-person processes. The intervention process and participants’ perception of the interventions will be assessed through a process evaluation. Intervention results will be analyzed by performing mixed model repeated measures analyses and multilevel analyses. RESULTS This study is supported by the Netherlands Organization for Applied Scientific Research Work and Health Research Program, which is funded by the Ministry of Economic Affairs and supported by the Dutch Ministry of Social Affairs and Employment, program number 19.204.1-3. This study was approved by the institutional review board on February 7, 2019. From June to August 2019, baseline data were collected, and from November to December 2019, the first follow-up data were collected. The second follow-up data collection and data analysis are planned for the first two quarters of 2020. Dissemination of the results is planned for the last two quarters of 2020. CONCLUSIONS A strength of this study design is the participatory action approach to enhance the stakeholder commitments, intervention adherence, and compliance. Moreover, since the target group will be participating in the development and implementation of the intervention, the proposed impact will be high. In addition, the short-term as well as the long-term effects will be evaluated. Finally, this study uses a unique combination of quantitative and qualitative evaluation methods. A limitation of this study is that it is impossible to randomly assign participants to an intervention or control group. Furthermore, the follow-up period (6 months) might be too short to establish health-related effects. Lastly, the results of this study might be specific to the department, organization, or sector, which limits the generalizability of the findings. However, as workplace intervention research for shift workers is scarce, this study might serve as a starting point for future research on shift work interventions.

BackgroundMelanocortin-4 receptor (MC4R) mutations are the most common of the rare monogenic forms of obesity. However, the efficacy of bariatric surgery (BS) and pharmacotherapy on weight and glycemic control in individuals with MC4R deficiency (MC4R-d) is not well-established. We investigated and compared the outcomes of BS and pharmacotherapy in patients with and without MC4R-d.MethodsPertinent details were derived from the electronic database among identified patients who had BS with MC4R-d (study group, SG) and wild-type controls (age- and sex-matched control group, CG). Short- and long-term outcomes were reported for the SG. Short-term outcomes were compared between the two groups.ResultsSeventy patients were screened for MC4R-d. The SG [six individuals (four females, two males); 18 (10–27) years old at BS; 50.3 (41.8–61.9) kg/m2 at BS, three patients with homozygous T162I mutations, two patients with heterozygous T162I mutations, and one patient with heterozygous I170V mutation] had a follow-up duration of up to 10 years. Weight loss, which varied depending on mutation type [17.99 (6.10–22.54) %] was stable for 6 months; heterogeneity of results was observed thereafter. BS was found superior to liraglutide on weight and glycemic control outcomes. At a median follow-up of 6 months, no significant difference was observed on weight loss (20.8% vs. 23.0%, p = 0.65) between the SG and the CG [eight individuals (four females, four males); 19.0 (17.8–36.8) years old at BS, 46.2 (42.0–48.3) kg/m2 at BS or phamacotherapeutic intervention]. Glycemic control in patients with MC4R-d and Type 2 diabetes improved post-BS.ConclusionOur data indicate efficacious short-term but varied long-term weight loss and glycemic control outcomes of BS on patients with MC4R-d, suggesting the importance of ongoing monitoring and complementary therapeutic interventions.

BackgroundEducation Not Discrimination (END) is the component of the Time to Change programme intended to reduce mental health stigma among professionals and professional trainees.AimsTo investigate the impact of the END anti-stigma programme on medical students immediately and after 6 months with regard to knowledge, attitudes, behaviour and empathy.MethodA total of 1452 medical students participated in the study (intervention group n = 1066, control group n = 386).Participants completed questionnaires at baseline, and at immediate and 6-month follow-up. Groups were compared for changes in stigma outcomes.ResultsAll measures improved in both groups, particularly among students with less knowledge and more stigmatising attitudes and intended behaviour at baseline. At immediate follow-up the intervention group demonstrated significantly greater improvements in stigma-related knowledge and reductions in stigma-related attitudes and intended behaviour, relative to the control group. At 6 months' follow-up, however, only one attitude item remained significantly better.ConclusionsAlthough the intervention produced short-term advantage there was little evidence for its persistent effect, suggesting a need for greater integration of ongoing measures to reduce stigma into the medical curriculum.
