Abstract
Aims Prior cost-effectiveness analyses on osseointegrated prosthesis for transfemoral unilateral amputees have analyzed outcomes in non-USA countries using generic quality of life instruments, which may not be appropriate when evaluating disease-specific quality of life. These prior analyses have also focused only on patients who had failed a socket-based prosthesis. The aim of the current study is to use a disease-specific quality of life instrument, which can more accurately reflect a patient's quality of life with this condition in order to evaluate cost-effectiveness, examining both treatment-naïve and socket refractory patients. Methods Lifetime Markov models were developed evaluating active healthy middle-aged male amputees. Costs of the prostheses, associated complications, use/non-use, and annual costs of arthroplasty parts and service for both a socket and osseointegrated (OPRA) prosthesis were included. Effectiveness was evaluated using the questionnaire for persons with a transfemoral amputation (Q-TFA) until death. All costs and Q-TFA were discounted at 3% annually. Sensitivity analyses on those cost variables which affected a change in treatment (OPRA to socket, or socket to OPRA) were evaluated to determine threshold values. Incremental cost-effectiveness ratios (ICERs) were calculated. Results For treatment-naïve patients, the lifetime ICER for OPRA was $279/quality-adjusted life-year (QALY). For treatment-refractory patients the ICER was $273/QALY. In sensitivity analysis, the variable thresholds that would affect a change in the course of treatment based on cost (from socket to OPRA), included the following for the treatment-naïve group: yearly replacement components for socket > $8,511; cost yearly replacement parts OPRA < $1,758; and for treatment-refractory group: yearly replacement component for socket of > $12,467. Conclusion The use of the OPRA prosthesis in physically active transfemoral amputees should be considered as a cost-effective alternative in both treatment-naïve and treatment-refractory socket prosthesis patients. Disease-specific quality of life assessments such as Q-TFA are more sensitive when evaluating cost-effectiveness.

Abstract
INTRODUCTION PD catheter tip migration is a common complication and a significant cause of catheter malfunction. In this perspective, we present our experience with a new catheter and a new technique that involves the use of a new triple cuff PD catheter and a low entry site in an attempt to prevent PD catheter migration. METHODS A total of 503 incident PD patients have been studied in more than one PD center over a period of 5 years. RESULTS During the 5-year follow up we recorded zero percent catheter migration. Other technical complications were poor drainage in 3.4%, omental wrap in 2.8%, early leakage in 3.4%, and catheter replacement in 2.4%. By the end of the study, the one-year PD catheter survival was 97.6%. CONCLUSION Our new triple cuff PD catheter and our low-entry approach seem to be effective in preventing PD catheter migration and minimizing other mechanical complications.

Abstract
Antibiotic cement articulating spacers eradicate infection during a two-stage revision for advanced septic hip arthritis (ASHA); however, mechanical complications have been reported. We hypothesized that the rate of mechanical complications would be lower in medullary-sparing (MS) than in non-medullary-sparing (n-MS) articulating spacers. A retrospective study of ASHA using n-MS or MS spacers was conducted between 1999 and 2019. The rate of mechanical complications and reoperation and risk factors for mechanical complications were analyzed. The cohort included 71 n-MS and 36 MS spacers. All patients were followed up for 2 years. The rate of spacer dislocation was lower in MS (0%) than in n-MS spacers (14.1%; p = 0.014). The reoperation rate for mechanical complications was lower in MS (0%) than in n-MS spacers (12.7%; p = 0.019). The rate of a diaphyseal stem during reimplantation was lower in MS (0%) than in n-MS spacers (19.4%; p = 0.002). The identified risk factors for n-MS spacer dislocation were postoperative under-restored femoral head diameter ≥3 mm, femoral offset ≥3 mm, and surgical volume (≤6 resection arthroplasties per year). Both spacers controlled infection. However, MS spacers had a lower spacer dislocation and reoperation rate and avoided the diaphyseal stem during reimplantation. We recommend using MS spacers to restore native femoral head diameter and femoral offset when ASHA is treated by surgeons with lower surgical volumes.

Abstract
Background Left ventricular free-wall rupture (LVFWR) is a catastrophic complication of acute myocardial infarction (AMI). Historically, cardiac surgery is considered the treatment of choice. However, because of the rarity of this entity, little is known regarding the efficacy and safety of surgical treatment for post-infarction LVFWR. The aim of this study was to report a single-center experience in this field over a period of 30 years. Methods Patients who developed LVFWR following AMI and underwent surgical repair at our Institution from January 1990 to December 2019 were considered. The primary end-point was in-hospital morality rate; secondary outcomes were long-term survival and postoperative complications. Multivariate analysis was carried out by constructing a logistic regression model to identify risk factors for early mortality. Results A total of 35 patients were enrolled in this study. The mean age was 68.9 years; 65.7% were male. The oozing type of LVFWR was encountered in 29 individuals, and the blowout type in 6 subjects. Sutured repair was used in 77.1% of patients, and sutureless repair in the remaining cases. The in-hospital mortality rate was 28.6%. Low cardiac output syndrome was the main cause of postoperative death. Multivariable analysis identified age >75 years at operation, preoperative cardiac arrest, concurrent ventricular septal rupture (VSR) as independent predictors of in-hospital death. Follow-up was complete in 100% of patients who survived surgery (mean follow-up: 9.3 ± 7.8 years); among the survivors, 16 patients died during the follow-up with a 3-year and 12-year overall survival rate of 82.5% and 55.2%, respectively. Conclusions Surgical treatment of LVFWR following AMI is possible with acceptable in-hospital mortality and excellent long-term results. Advanced age, concurrent VSR and cardiac arrest at presentation are independent risk factors of poor early outcome.

Abstract
BACKGROUND Mechanical complications (MC) are rare but significant sequelae of acute myocardial infarction (AMI). Current data on sex differences in AMI with MC is limited. METHODS We queried the National Inpatient Sample database to identify adult patients with the primary diagnosis of AMI and MC. The main outcome of interest was sex difference in-hospital mortality. Secondary outcomes were sex differences in the incidence of acute kidney injury (AKI), major bleeding, use of inotropes, permanent pacemaker implantation (PPMI), performance of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), surgery (VSD repair and MV surgery), pericardiocentesis, use of mechanical circulatory support (MCS), ischemic stroke, and mechanical ventilation. RESULTS Among AMI-MC cohort, in-hospital mortality was higher among females compared to males (41.24% vs 28.13%: aOR 1.39. 95% CI 1.079-1.798; p = 0.01). Among those who had VSD, females also had higher in-hospital mortality compared to males (56.7% vs 43.1%: aOR 1.74, 95% CI 1.12-2.69; p = 0.01). Females were less likely to receive CABG compared to males (12.03% vs 20%: aOR 0.49 95% CI 0.345-0.690; p < 0.001). CONCLUSION Despite the decreasing trend in AMI admission, females had higher risk of MC and associated mortality. Significant sex disparities still exist in AMI treatment.

Abstract
PURPOSE To evaluate the survival of and incidence of mechanical complications with single- and multiple-unit cement-retained posterior implant-supported restorations with custom CAD/CAM Atlantis titanium abutments (Dentsply Sirona, Charlotte, NC, USA). MATERIALS AND METHODS This retrospective clinical study analysed 196 Astra Tech OsseoSpeed TX Internal Hexagon implants (Dentsply Sirona) placed in 85 patients between January 2011 and January 2021. Customised Atlantis titanium abutments and cement-retained metal-ceramic crowns were employed. The clinical outcomes recorded were implant and abutment survival rates, and mechanical complications. The results were analysed according to implant length and diameter, arch, implant position and single- or multiple-unit restoration. RESULTS Over the observation period (up to 10 years), implant and abutment survival rates were 98.5% and 100.0%, respectively. The mean observation period for the single- and multiple-unit implant-supported restorations was 106.00 ± 20.84 months, with a minimum of 41 months and a maximum of 120 months. For the 67 single-unit and 129 multiple-unit posterior implant-supported restorations, four mechanical complications were recorded: two cases of screw loosening, one case of chipping or fracture of veneering materials, and one case of crown decementation. No screw or abutment fractures were observed. CONCLUSIONS According to the results of this retrospective clinical study, cement-retained posterior implant-supported restorations with custom CAD/CAM Atlantis titanium abutments showed high survival rates over a follow-up period of up to 10 years. No statistically significant differences were recorded when comparing implant position, implant diameter, implant length, single- versus multiple-unit restoration and arch.

Abstract
Aims This work aimed at answering the following research questions: 1) What is the rate of mechanical complications, nonunion and infection for head/neck femoral fractures, intertrochanteric fractures, and subtrochanteric fractures in the elderly USA population? and 2) Which factors influence adverse outcomes? Methods Proximal femoral fractures occurred between 1 January 2009 and 31 December 2019 were identified from the Medicare Physician Service Records Data Base. The Kaplan-Meier method with Fine and Gray sub-distribution adaptation was used to determine rates for nonunion, infection, and mechanical complications. Semiparametric Cox regression model was applied incorporating 23 measures as covariates to identify risk factors. Results Union failure occured in 0.89% (95% confidence interval (CI) 0.83 to 0.95) after head/neck fracturs, in 0.92% (95% CI 0.84 to 1.01) after intertrochanteric fracture and in 1.99% (95% CI 1.69 to 2.33) after subtrochanteric fractures within 24 months. A fracture-related infection was more likely to occur after subtrochanteric fractures than after head/neck fractures (1.64% vs 1.59%, hazard ratio (HR) 1.01 (95% CI 0.87 to 1.17); p < 0.001) as well as after intertrochanteric fractures (1.64% vs 1.13%, HR 1.31 (95% CI 1.12 to 1.52); p < 0.001). Anticoagulant use, cerebrovascular disease, a concomitant fracture, diabetes mellitus, hypertension, obesity, open fracture, and rheumatoid disease was identified as risk factors. Mechanical complications after 24 months were most common after head/neck fractures with 3.52% (95% CI 3.41 to 3.64; currently at risk: 48,282). Conclusion The determination of complication rates for each fracture type can be useful for informed patient-clinician communication. Risk factors for complications could be identified for distinct proximal femur fractures in elderly patients, which are accessible for therapeutical treatment in the management.

Abstract
Background: Cervical spine clearance in intubated patients due to blunt trauma remains contentious. Accumulating evidence suggests that a normal computed tomography (CT) cervical spine can be used to clear the cervical spine and remove the collar in unconscious patients presenting to the emergency department. However, whether this strategy can safely be employed by critical care physicians with intubated patients admitted to the trauma intensive care unit (TICU) with cervical collars in situ, has not been definitively studied. Methods: A retrospective review of 730 intubated victims of trauma who presented to the Level 1 Trauma center of a tertiary hospital was conducted. The rates of missed cervical injuries in patients who had their cervical collars removed by intensive care physicians based on a normal CT scan of the cervical spine, were reviewed. Secondary outcomes included rates of collar-related complications. Results: Three hundred and fifty patients had their cervical collars removed by Trauma ICU doctors based on a high-quality, radiologist-interpreted normal CT cervical spine. Seventy percent of patients were sedated and/or comatose at the time of collar removal. Fifty-one percent of patients had concomitant traumatic brain injury. The average GCS at time of collar removal was 9. The incidence of missed neurological injury discerned clinically at time of both ICU and hospital discharge was nil (negative predictive value 100%). The rate of collar-related complications was 2%. Conclusion: Cervical collar removal by intensive care physicians on TICU following normal CT cervical spine, is safe, provided certain quality conditions related to the CT scan are met. Not removing the collar early may be associated with increased complications. An algorithm is suggested to assist critical care decision-making in this patient cohort.

Abstract
INTRODUCTION With the increasing demand for total knee arthroplasty (TKA) and the burden of revision TKA on the healthcare system, as well as the quality of life implications for patients, it is extremely important for surgeons to be able to anticipate and prevent TKA mechanical complications. Surgeons must be familiar with the different causes and mechanisms of TKA complications so that they can properly treat patients with failed TKAs and better avoid these complications. AREAS COVERED This review addresses TKA mechanical complications and provides context for the topic. A detailed review of surgical factors, implant factors, and patient factors that contribute to mechanical complications after TKA is provided. All of the literature cited in this review was gathered from the PubMed online database using different keywords based on the section of the manuscript. EXPERT OPINION As surgeons and engineers solve certain issues in TKA, new challenges will inevitably arise. We must continue to push forward and innovate from both a surgical technique and implant design perspective.

Abstract
Background Low bone mineral density (BMD) is a well-established risk factor for mechanical complications following adult spinal deformity (ASD) surgery. Hounsfield units (HU) measured on computed tomography (CT) scans are a proxy of BMD. In ASD surgery, we sought to: (I) evaluate the association of HU with mechanical complications and reoperation, and (II) identify optimal HU threshold to predict the occurrence of mechanical complications. Methods A single-institution retrospective cohort study was undertaken for patients undergoing ASD surgery from 2013-2017. Inclusion criteria were: ≥5-level fusion, sagittal/coronal deformity, and 2-year follow-up. HU were measured on 3 axial slices of one vertebra, either at the upper instrumented vertebra (UIV) itself or UIV ±4 from CT scans. Multivariable regression controlled for age, body mass index (BMI), postoperative sagittal vertical axis (SVA), and postoperative pelvic-incidence lumbar-lordosis mismatch. Results Of 145 patients undergoing ASD surgery, 121 (83.4%) had a preoperative CT from which HU were measured. Mean age was 64.4±10.7 years, mean total instrumented levels was 9.8±2.6, and mean HU was 153.5±52.8. Mean preoperative SVA and T1PA were 95.5±71.1 mm and 28.8°±12.8°, respectively. Postoperative SVA and T1PA significantly improved to 61.2±61.6 mm (P<0.001) and 23.0°±11.0° (P<0.001). Mechanical complications occurred in 74 (61.2%) patients, including 42 (34.7%) proximal junctional kyphosis (PJK), 3 (2.5%) distal junctional kyphosis (DJK), 9 (7.4%) implant failure, 48 (39.7%) rod fracture/pseudarthrosis, and 61 (52.2%) reoperations within 2 years. Univariate logistic regression showed a significant association between low HU and PJK [odds ratio (OR) =0.99; 95% confidence interval (CI): 0.98-0.99; P=0.023], but not on multivariable analysis. No association was found regarding other mechanical complications, overall reoperations, and reoperations due to PJK. HU below 163 were associated with increased PJK on receiver operating characteristic (ROC) curve analysis [area under the curve (AUC) =0.63; 95% CI: 0.53-0.73; P<0.001]. Conclusions Though several factors contribute to PJK, it appears that 163 HU may serve as a preliminary threshold when planning ASD surgery to mitigate the risk of PJK.

Abstract
A 61-year-old male patient diagnosed with Coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS) was managed with tracheostomy and intermittent prone positioning in the intensive care unit. After a sudden deterioration, examination of tracheostomy tube (TT) and X-ray of the chest revealed that he had aspirated the fractured TT. The fractured tube was removed through the tracheostomy stoma using a rigid ventilating bronchoscope and forceps. Prone positioning is a beneficial postural therapy capable of improving patient oxygenation. However, it has some complications, like unplanned extubation and facial tissue injury. Percutaneous tracheostomy is also a valuable and safe procedure and has been increasingly performed in critical care patients, including those who suffer from COVID-19 ARDS. Fractures and aspiration of a tracheostomy tube can occur anytime after tracheostomy. We think prone positioning may contribute to the rupture and aspiration of the tracheostomy tube in this study.

Abstract
PURPOSE To determine the survival rate, incidence of prosthetic complications, and patient satisfaction of implant fixed complete dental prostheses (IFCDPs) after a mean observation period of 1.4 years. MATERIALS AND METHODS Twenty-eight (28) eligible participants were recruited according to specific inclusion and exclusion criteria. The definitive metal-acrylic resin IFCDPs consisted of titanium bars veneered with acrylic resin and acrylic denture teeth. Prosthodontic complications, divided into major and minor, were monitored. Parameters such as gender, jaw location, bruxism, and occlusal scheme were evaluated. Moreover, a questionnaire was administered throughout the study to assess patient satisfaction. Poisson regression as well as repeated measures ANOVA were used for statistical analysis. RESULTS Fourteen (14) males and 14 females were enrolled and followed-up at 3, 6, and 12 months. All IFCDPs survived (100% survival rate). The most frequent minor complication was the loss of material used to close the screw access hole (20% out of total complications). The most frequent major complication was chipping of the acrylic denture teeth (77.14% out of total complications). Gender (p = 0.008) and bruxism (p = 0.030) were significant predictors for the total major complications (major wear and major chipping) while occlusal scheme was a significant predictor for major chipping events (p = 0.030). CONCLUSIONS While IFCDPs demonstrated high prosthetic survival rates, they also exhibited a high number of chipping events of the acrylic veneering material, especially in males, bruxers, and individuals with canine guidance occlusion. However, the occurrence of these prosthetic complications did not negatively affect patient satisfaction.

Abstract
OBJECTIVE The Global Alignment and Proportion (GAP) score was developed to serve as a tool to predict mechanical complication probability in patients undergoing surgery for adult spinal deformity (ASD), serving as an aid for setting surgical goals to decrease the prevalence of mechanical complications in ASD surgery. However, it was developed using ASD patients for whom open surgical techniques were used for correction. Therefore, the purpose of this study was to assess the applicability of the score for patients undergoing circumferential minimally invasive surgery (cMIS) for correction of ASD. METHODS Study participants were patients undergoing cMIS ASD surgery without the use of osteotomies with a minimum of four levels fused and 2 years of follow-up. Postoperative GAP scores were calculated for all patients, and the association with mechanical failure was analyzed. RESULTS The authors identified 182 patients who underwent cMIS correction of ASD. Mechanical complications were found in 11.1% of patients with proportioned spinopelvic states, 20.5% of patients with moderately disproportioned spinopelvic states, and 18.8% of patients with severely disproportioned spinopelvic states. Analysis with a chi-square test showed a significant difference between the cMIS and original GAP study cohorts in the moderately disproportioned and severely disproportioned spinopelvic states, but not in the proportioned spinopelvic states. CONCLUSIONS For patients stratified into proportioned, moderately disproportioned, and severely disproportioned spinopelvic states, the GAP score predicted 6%, 47%, and 95% mechanical complication rates, respectively. The mechanical complication rate in patients undergoing cMIS ASD correction did not correlate with the calculated GAP spinopelvic state.

Abstract
Aims COVID-19 has dramatically impacted the healthcare system. Evidence from previous studies suggests a decline in in-hospital admissions for acute myocardial infarction (AMI) during the pandemic. However, the effect of the pandemic on mechanical complications (MC) in acute ST-segment elevation myocardial infarction (STEMI) has not been comprehensively investigated. Therefore, we evaluated the impact of the pandemic on MC and in-hospital outcomes in STEMI during the second wave, in which there was a huge SARS-CoV-2 diffusion in Italy. Methods and results Based on a single center cohort of AMI patients admitted with STEMI between February 1, 2019, and February 28, 2021, we compared the characteristics and outcomes of STEMI patients treated during the pandemic vs. those treated before the pandemic. In total, 479 STEMI patients were included, of which 64.5% were during the pandemic. Relative to before the pandemic, primary percutaneous coronary intervention (PCI) declined (87.7 vs. 94.7%, p = 0.014) during the pandemic. Compared to those admitted before the pandemic (10/2019 to 2/2020), STEMI patients admitted during the second wave (10/2020 to 2/2021) presented with a symptom onset-to-door time greater than 24 h (26.1 vs. 10.3%, p = 0.009) and a reduction of primary PCI (85.2 vs. 97.1%, p = 0.009). MC occurred more often in patients admitted during the second wave of the pandemic than in those admitted before the pandemic (7.0 vs. 0.0%, p = 0.032). In-hospital mortality increased during the second wave (10.6 vs. 2.9%, p = 0.058). Conclusion Although the experience gained during the first wave and a more advanced hub-and-spoke system for cardiovascular emergencies persists, late hospitalizations and a high incidence of mechanical complications in STEMI were observed even in the second wave.

Abstract
BACKGROUND Individualised PEEP may optimise pulmonary compliance, thereby potentially mitigating lung injury. This meta-analysis aimed to determine the impact of individualised PEEP vs fixed PEEP during abdominal surgery on postoperative pulmonary outcomes. METHODS Medical databases (PubMed, Embase, Web of Science, ScienceDirect, Google Scholar, and the China National Knowledge Infrastructure) were searched for RCTs comparing fixed vs individualised PEEP. The composite primary outcome of pulmonary complications comprised hypoxaemia, atelectasis, pneumonia, and acute respiratory distress syndrome. Secondary outcomes included oxygenation (PaO2/FiO2) and systemic inflammatory markers (interleukin-6 [IL-6] and club cell protein-16 [CC16]). We calculated risk ratios (RRs) and mean differences (MDs) with 95% confidence interval (CI) using DerSimonian and Laird random effects models. Cochrane risk-of-bias tool was applied. RESULTS Ten RCTs (n=1117 patients) met the criteria for inclusion, with six reporting the primary endpoint. Individualised PEEP reduced the incidence of overall pulmonary complications (141/412 [34.2%]) compared with 183/415 (44.1%) receiving fixed PEEP (RR 0.69 [95% CI: 0.51-0.93]; P=0.016; I2=43%). Risk-of-bias analysis did not alter these findings. Individualised PEEP reduced postoperative hypoxaemia (74/392 [18.9%]) compared with 110/395 (27.8%) participants receiving fixed PEEP (RR 0.68 [0.52-0.88]; P=0.003; I2=0%) but not postoperative atelectasis (RR 0.93 [0.81-1.07]; P=0.297; I2=0%). Individualised PEEP resulted in higher PaO2/FiO2 (MD 20.8 mm Hg [4.6-36.9]; P=0.012; I2=80%) and reduced systemic inflammation (lower plasma IL-6 [MD -6.8 pg ml-1; -11.9 to -1.7]; P=0.009; I2=6%; and CC16 levels [MD -6.2 ng ml-1; -8.8 to -3.5]; P<0.001; I2=0%) at the end of surgery. CONCLUSIONS Individualised PEEP may reduce pulmonary complications, improve oxygenation, and reduce systemic inflammation after abdominal surgery. CLINICAL TRIAL REGISTRATION CRD42021277973.

Abstract
AIMS Registry studies on modified acetabular polyethylene (PE) liner designs are limited. We investigated the influence of standard and modified PE acetabular liner designs on the revision rate for mechanical complications in primary cementless total hip arthroplasty (THA). METHODS We analyzed 151,096 primary cementless THAs from the German Arthroplasty Registry (EPRD) between November 2012 and November 2020. Cumulative incidence of revision for mechanical complications for standard and four modified PE liners (lipped, offset, angulated/offset, and angulated) was determined using competing risk analysis at one and seven years. Confounders were investigated with a Cox proportional-hazards model. RESULTS Median follow-up was 868 days (interquartile range 418 to 1,364). The offset liner design reduced the risk of revision (hazard ratio (HR) 0.68 (95% confidence interval (CI) 0.50 to 0.92)), while the angulated/offset liner increased the risk of revision for mechanical failure (HR 1.81 (95% CI 1.38 to 2.36)). The cumulative incidence of revision was lowest for the offset liner at one and seven years (1.0% (95% CI 0.7 to 1.3) and 1.8% (95% CI 1.0 to 3.0)). No difference was found between standard, lipped, and angulated liner designs. Higher age at index primary THA and an Elixhauser Comorbidity Index greater than 0 increased the revision risk in the first year after surgery. Implantation of a higher proportion of a single design of liner in a hospital reduced revision risk slightly but significantly (p = 0.001). CONCLUSION The use of standard acetabular component liners remains a good choice in primary uncemented THA, as most modified liner designs were not associated with a reduced risk of revision for mechanical failure. Offset liner designs were found to be beneficial and angulated/offset liner designs were associated with higher risks of revision. Cite this article: Bone Joint J 2022;104-B(7):801-810.

Abstract
Background Ventricular septal rupture (VSR) following acute myocardial infarction (AMI) is a dangerous condition. Surgical VSR closure is the definitive therapy, but there is controversy regarding the surgical timing and the bridging therapy between diagnosis and intervention. The objective of this study is to analyze the ideal time of surgical repair and to establish the contribution of mechanical circulatory support (MCS) devices on the prognosis. Methods We designed an observational, retrospective, multicenter study, selecting all consecutive patients with post-AMI VSR between January 1, 2008 and December 31, 2018, with non-exclusion criteria. The main objective of this study was to analyze the optimal timing for surgical repair of post-AMI VSR. Secondary endpoints were to determine which factors could influence mortality in the patients of the surgical group. Results A total of 141 patients were included. We identified lower mortality rates with an odds ratio of 0.3 (0.1–0.9) in patients operated on from day 4 compared with the surgical mortality in the first 24 hours after VSR diagnosis. The use of MCS was more frequent in patients treated with surgery, particularly for intra-aortic balloon pump (IABP; 79.6% vs. 37.8%, p < 0.001), but also for veno-arterial extracorporeal membrane oxygenation (VA-ECMO; 18.2% vs. 6.4%, p = 0.134). Total mortality was 91.5% for conservative management and 52.3% with surgical repair (p < 0.001). Conclusions In our study, we observed that the lowest mortality rates in patients with surgical repair of post-AMI VSR were observed in patients operated on from day 4 after diagnosis of VSR, compared to earlier interventions.

Abstract
BACKGROUND Mechanical complications of acute myocardial infarction represent life-threatening events, including ventricular septal rupture (VSR), left ventricular free-wall rupture (LVFWR) and papillary muscle rupture (PMR). In-hospital mortality is high, even when prompt surgery can be offered. The role of concomitant coronary artery bypass grafting (CABG) in the surgical treatment of these conditions is still debated. METHODS A systematic review of the literature, from 2000 onwards, about these complications was performed, analyzing data of subjects receiving versus not-receiving concomitant CABG. Primary outcome was early mortality. Secondary outcome was late mortality for hospital survivors. Subgroup analysis for VSR, LVFWR and PMR was also performed. RESULTS Thirty-six studies were identified, including 4,321 patients (mostly VSR-related). Preoperative coronarography was performed in 92.2% of the cases, showing single-vessel disease in 54.3% of patients. Concomitant CABG rate was 49.0%. Early mortality was 32.6% and late mortality was 40.0% with 5.2 years of mean follow-up. The analysis showed no difference in early (OR 0.96; P=0.60) or late mortality (RR 0.91; P=0.49) between CABG and non-CABG group. In subgroup analysis, concomitant CABG was associated with significantly lower mortality at long term for PMR (RR 0.42; P=0.001), although it showed a higher, but not significant, mortality in VSR (RR 1.24; P=0.20). CONCLUSIONS Concomitant CABG in the treatment for post-infarction mechanical complications showed no significant impact on both early and late mortality, although deserving some distinctions among different types of complication and single versus multiple vessel disease. However, larger, dedicated studies are required to provide more consistent data and evidence.

Abstract
The causal effects of rheumatoid arthritis (RA) on complications of arthroplasty are yet to be established. This study was the first to explore the causal effect of RA on mechanical complications of prosthesis through two-sample Mendelian randomization (MR). In the MR analysis, RA was selected as the exposure in this study while single-nucleotide polymorphisms (SNPs) from a genome-wide association study (GWAS) were selected as the instrumental variables (IVs). Summary statistics data on mechanical complications of prosthesis was extracted from publicly available GWAS data, including 463,010 European descent individuals. MR analysis was performed using the standard inverse variance weighted method (IVW). Furthermore, other methods (MR Egger, weighted median, simple mode, and weighted mode) were also done to verify the results. Finally, the sensitivity analysis was executed. Results of the standard IVW showed that RA possibly increases the risk of mechanical complications of prosthesis [OR = 1.000255; 95% CI = (1.0001035, 1.000406); p = 9.69 × 10 -4 ]. This outcome was also verified by other methods including weighted median [OR = 1.000285; 95% CI = (1.0001032, 1.000466); p = 1.41 × 10-3], simple mode [OR = 1.000446; 95% CI = (1.0001116, 1.000781); p = 1.04 × 10-2], and weighted mode [OR = 1.000285; 95% CI = (1.0001032, 1.000466); p = 2.29 × 10-3]. No heterogeneity and directional pleiotropy was observed upon sensitivity analysis, indicating the stability and reliability of the result. In summary, the present study showed that RA potentially increases the risks of complications of prosthesis, which might provide guidance in arthroplasty on RA patients.

Abstract
AIMS The current study aimed to compare robotic arm-assisted (RA-THA), computer-assisted (CA-THA), and manual (M-THA) total hip arthroplasty regarding in-hospital metrics including length of stay (LOS), discharge disposition, in-hospital complications, and cost of RA-THA versus M-THA and CA-THA versus M-THA, as well as trends in use and uptake over a ten-year period, and future projections of uptake and use of RA-THA and CA-THA. METHODS The National Inpatient Sample was queried for primary THAs (2008 to 2017) which were categorized into RA-THA, CA-THA, and M-THA. Past and projected use, demographic characteristics distribution, income, type of insurance, location, and healthcare setting were compared among the three cohorts. In-hospital complications, LOS, discharge disposition, and in-hospital costs were compared between propensity score-matched cohorts of M-THA versus RA-THA and M-THA versus CA-THA to adjust for baseline characteristics and comorbidities. RESULTS RA-THA and CA-THA did not exhibit any clinically meaningful reduction in mean LOS (RA-THA 2.2 days (SD 1.4) vs 2.3 days (SD 1.8); p < 0.001, and CA-THA 2.5 days (SD 1.9) vs 2.7 days (SD 2.3); p < 0.001, respectively) compared to their respective propensity score-matched M-THA cohorts. RA-THA, but not CA-THA, had similar non-home discharge rates to M-THA (RA-THA 17.4% vs 18.5%; p = 0.205, and 18.7% vs 24.9%; p < 0.001, respectively). Implant-related mechanical complications were lower in RA-THA (RA-THA 0.5% vs M-THA 3.1%; p < 0.001, and CA-THA 1.2% vs M-THA 2.2%; p < 0.001), which was associated with a significantly lower in-hospital dislocation (RA-THA 0.1% vs M-THA 0.8%; p < 0.001). Both RA-THA and CA-THA demonstrated higher mean higher index in-hospital costs (RA-THA $18,416 (SD $8,048) vs M-THA $17,266 (SD $8,396); p < 0.001, and CA-THA $20,295 (SD $8,975) vs M-THA $18,624 (SD $9,226); p < 0.001, respectively). Projections indicate that 23.9% and 3.2% of all THAs conducted in 2025 will be robotic arm- and computer-assisted, respectively. Projections indicated that RA-THA use may overtake M-THA by 2028 (48.3%) and reach 65.8% of all THAs by 2030. CONCLUSION Technology-assisted THA, particularly RA-THA, may provide value by lowering in-hospital early dislocation rates and and other in-hospital metrics compared to M-THA. Higher index-procedure and hospital costs warrant further comprehensive cost analyses to determine the true added value of RA-THA in the episode of care, particularly since we project that one in four THAs in 2025 and two in three THA by 2030 will use RA-THA technology.

Abstract
BACKGROUND CONTEXT Sagittal spinopelvic alignment has been associated with patient-reported outcome measures and mechanical complication rates. Recently, it was claimed that linear numerical values of pelvic tilt and lumbar lordosis measurements may be misleading for patients that have different magnitudes of pelvic incidence. The use of "relative" measurements embedded in a weighted scoring of Global Alignment and Proportion (GAP) was proposed. PURPOSE The purpose was to evaluate the GAP scorein an independent database. STUDY DESIGN/SETTING Retrospective Cohort Study PATIENT SAMPLE: Adult spinal deformity patients who underwent ≥7 levels posterior fusion to the pelvis between 2004 and 2014 were included. OUTCOME MEASURES Mechanical Complication Rates. METHODS Demographic, clinical, surgical and radiographic patient characteristics were recorded. Cochran-Armitage tests were used to compare mechanical complication rates in GAP categories. Uni and multivariable logistic regression analyses were used to obtain crude and adjusted Odds Ratios, of predictor (GAP categories) and the outcome (mechanical complication), and Risk Ratios were calculated. The diagnostic performance of the GAP score was tested using the area under the receiver operating characteristic curve, sensitivity, specificity, positive predictive value, negative predictive value and accuracy in predicting mechanical complications. RESULTS A total of 322 patients (285F, 37M) with a mean age of 58.2±9.6 were analyzed. Mean follow-up was 69.7 months (range 24 to 177). Mechanical complications occurred in 52.2% of the patients. Mechanical complication rates in proportioned (GAP-P), moderately (GAP-MD) and severely disproportioned (GAP-SD) patients were 21.8%, 55.1%, and 70.4%, respectively. AUC for the GAP score, at 2 years, was 0.682 (95% CI, 0.624 to 0.741, p<.001). AUC at minimum 5 years follow-up was similar at 0.708, while AUC at minimum 7- and 12-year follow-up were 78.5 and 90.7, respectively. Having a postoperative spinopelvic alignment of GAP-MD and GAP-SD resulted in 2.5 and 3.2 folds of relative risk in incurring a mechanical complication when compared to having a proportioned spinopelvic state, respectively. CONCLUSIONS This study reports an association between the GAP Score and mechanical complications in an independent database. Increased association was noted as the years of follow-up increased. Aiming to achieve proportionate GAP Score postoperatively seems to be a viable option as lower GAP scores were associated with lower rates of mechanical complications, and vice versa.

Abstract
PURPOSE To evaluate and compare the implant survival rates, marginal bone loss, and mechanical complications of prostheses supported by splinted and nonsplinted short implants (≤8.5 mm). MATERIAL AND METHODS Electronic database (MEDLINE, CENTRAL, Web of Science, and EMBASE) and manual searches up to May 2021 were conducted to identify studies comparing splinted and nonsplinted short implants (≤8.5 mm). The primary outcome was implant survival rate. Secondary outcomes were marginal bone loss and mechanical complications. The quality of included studies and risk-of-bias were assessed according to the Newcastle-Ottawa Scale. A random-effects model was used to analyze the data. RESULTS Twelve studies fulfilled the inclusion criteria and featured 1506 short implants (596 nonsplinted and 910 splinted) with a follow-up time ranging from 1 to 16 years. Quantitative analysis found no statistically significant differences between splinted and nonsplinted short implants (≤8.5 mm) for survival rate (RR = 0.98; 95% CI 0.96, 1.01; p = 0.26)) and marginal bone loss (SMD = -0.08; 95% CI - 0.23, 0.07; p = 0.28). Veneer chipping, abutment screw breakage, screw loosening, and loss of retention were reported in the selected studies as common complications. However, no statistically significant difference was found between splinted and nonsplinted short implants (RR = 0.56; 95% CI 0.20, 1.54; p = 0.26). CONCLUSIONS Within the limitations of the present meta-analysis, it might be concluded that splinted short implants (≤8.5 mm) do not present superior performance in survival rate, marginal bone maintenance and prevention of mechanical complications compared with single-unit prostheses.

Abstract
Percutaneous peritoneal dialysis catheter (PDC) insertion for continuous ambulatory peritoneal dialysis (CAPD) entails a higher risk of complications such as bowel injury, vascular injury, and catheter migration compared to the surgical insertions. We conducted a comparative analysis of two techniques of peritoneal entry for PDC insertion by Seldinger technique. We performed a retrospective review of 426 percutaneously inserted PDCs in nonobese naïve abdomens for CAPD at two tertiary care teaching hospitals in India over 6 years. Comparison of various mechanical complications, and short-term catheter survival was done between use of introducer needle (Group "I") and spring-loaded pneumoperitoneum (Veress) needle (Group "V"). Group "I" to "V" patient ratio was 277:149. Group "I" had heavier patients (p = 0.03) whereas "V" group had a dominance of diabetes (p = 0.009) and prior hemodialysis patients (p = 0.03). At 3 months, the odds of mechanical complications (OR = 0.27, p = 0.004), PDC migration (OR = 0.18, p = 0.02), and omental wrapping (OR = 0.13, p = 0.04) were less in "V" group. No bowel injury occurred with Veress needle use. At 6 months, "V" group had higher odds of event-free sustained PDC tip position (OR = 0.39, p = 0.003), and catheter survival (p = 0.03), and the cumulative events were lesser too (p = 0.002). Refractory peritonitis and deaths with functioning catheter were comparable between both the groups. In this first-of-its-kind study, spring-loaded Veress pneumoperitoneum needle use was safer, entrusted sustained PDC tip position in pelvis, and had a better catheter survival compared to use of introducer needle for peritoneal entry in percutaneously inserted PDCs. These findings should be confirmed by a randomized controlled study.

Abstract
Amid the coronavirus disease 2019 (COVID-19) pandemic, there is an unprecedented increase in public avoidance of hospitals predominantly driven by fear of contracting the virus. Recent publications highlight a re-emergence of rare post-myocardial infarction complications. While mechanical complications are infrequent in the era of primary percutaneous coronary intervention, they are associated with high mortality rates. The concurrent occurrence of mechanical complications such as left ventricular aneurysm and ventricular septal rupture is an extremely rare entity. We hereby delineate a unique case of a 53-year-old Caucasian male who underwent successful concomitant closure of a ventricular septal rupture, left ventricular aneurysmectomy, and 3-vessel coronary artery bypass grafting. Due to a delayed initial presentation owing to the patient's fear of contracting COVID-19, the surgery was carried out 3 months after the myocardial infarction. His postoperative evaluation confirmed normal contractility of the left ventricle and complete closure of the ventricular septal rupture. Six months postoperatively, the patient continues to do well. We also present a literature review of the mechanical complications following delayed presentation of myocardial infarction amid the COVID-19 pandemic. This article illustrates that clinicians should remain cognizant of these extremely rare but potentially lethal collateral effects during the ongoing global public-health challenge. Furthermore, it highlights a significant concern regarding the delay in first medical contact due to the reluctance of patients to visit the hospital during the COVID-19 pandemic.

Abstract
This study aimed to analyze a novel technique to make screws with greater untightening resistance and to solve screw loosening in implant-supported single crowns. Thirty grade IV titanium straight abutments were screwed onto 30 external hex implants using grade IV titanium screws (30 Ncm). They were exposed to cyclic loading (300,000 cycles, 200 N). Samples were divided into 4 groups (15 samples per group): new screws (SCREW group) (control), reused screws (rSCREW group), new screws wrapped with polytetrafluoroethylene (PTFE) tape (PTFE group), and reused screws wrapped with PTFE tape (rPTFE group). Reverse torque values (RTVs) were recorded with a digitally calibrated implant motor. Mean RTVs observed were 14.46 N (±1.10 N) for the control group, 14.42 N (±1.22 N) for the rSCREW group, 19.97 N (±1.16 N) for the PTFE group, and 19.13 N (±2.38 N) for the rPTFE group. Statistically significant differences were found between RTVs of both groups employing screws without PTFE tape (SCREW and rSCREW groups) compared with those using screws wrapped with PTFE tape (PTFE and rPTFE) (p < 0.001). These results suggest that wrapping the implant–abutment screw with PTFE tape may effectively lower the risk of loosening and even constitute a solution when this complication occurs in implant single crowns.

Abstract
BACKGROUND Mechanical complications represent an important cause of mortality in myocardial infarction (MI) patients. This is a nationwide study performed to evaluate possible changes in epidemiology or prognosis of these complications with current available strategies. METHODS Information was obtained from the minimum basis data set of the Spanish National Health System, including all hospitalizations for acute myocardial infarction (AMI) from 2010 to 2015. Risk-standardized in-hospital mortality ratio was calculated using multilevel risk adjustment models. RESULTS A total of 241,760 AMI episodes were analyzed, MI mechanical complications were observed in 842 patients: cardiac tamponade in 587, ventricular septal rupture in 126, and mitral regurgitation due to papillary muscle or chordae tendineae rupture in 155 (there was more than one complication in 21 patients). In-hospital mortality was 59.5%. On multivariate adjustment, variables with significant impact on in-hospital mortality were: age (OR 1.06; 95% CI 1.04-1.07; p < 0.001), ST-segment elevation AMI (OR 2.91; 95% CI 1.88-4.5; p < 0.001), cardiogenic shock (OR 2.35; 95% CI 1.66-3.32; p < 0.001), cardio-respiratory failure (OR 3.48; 95% CI 2.37-5.09; p < 0.001), and chronic obstructive pulmonary disease (OR 1.85; 95% CI 1.07-3.20; p < 0.001). No significant trends in risk-adjusted in-hospital mortality were detected (IRR 0.997; p = 0.109). Cardiac intensive care unit availability and more experience with mechanical complications management were associated with lower adjusted mortality rates (56.7 ± 5.8 vs. 60.1 ± 4.5; and 57 ± 6.1 vs. 59.9 ± 5.6, respectively; p < 0.001). CONCLUSIONS Mechanical complications occur in 3.5 per thousand AMI, with no significant trends to better survival over the past few years. Advanced age, cardiogenic shock and cardio-respiratory failure are the most important risk factors for in-hospital mortality. Higher experience and specialized cardiac intensive care units are associated with better outcomes.

Abstract
OBJECTIVE The goal of this study was to validate the Global Alignment and Proportion (GAP) score in a cohort of patients undergoing adult spinal deformity (ASD) surgery. The GAP score is a novel measure that uses sagittal parameters relative to each patient's lumbosacral anatomy to predict mechanical complications after ASD surgery. External validation is required. METHODS Adult ASD patients undergoing > 4 levels of posterior fusion with a minimum 2-year follow-up were included. Six-week postoperative standing radiographs were used to calculate the GAP score, classified into a spinopelvic state as proportioned (P), moderately disproportioned (MD), or severely disproportioned (SD). A chi-square analysis, receiver operating characteristic curve, and Cochran-Armitage analysis were performed to assess the relationship between the GAP score and mechanical complications. RESULTS Sixty-seven patients with a mean age of 52.5 years (range 18-75 years) and a mean follow-up of 2.04 years were included. Patients with < 2 years of follow-up were included only if they had an early mechanical complication. Twenty of 67 patients (29.8%) had a mechanical complication. The spinopelvic state breakdown was as follows: P group, 21/67 (31.3%); MD group, 23/67 (34.3%); and SD group, 23/67 (34.3%). Mechanical complication rates were not significantly different among all groups: P group, 19.0%; MD group, 30.3%; and SD group, 39.1% (χ2 = 1.70, p = 0.19). The rates of mechanical complications between the MD and SD groups (30.4% and 39.1%) were less than those observed in the original GAP study (MD group 36.4%-57.1% and SD group 72.7%-100%). Within the P group, the rates in this study were higher than in the original study (19.0% vs 4.0%, respectively). CONCLUSIONS The authors found no statistically significant difference in the rate of mechanical complications between the P, MD, and SD groups. The current validation study revealed poor generalizability toward the authors' patient population.

Abstract
We aimed to assess the biological and mechanical-technical complications and survival rate of implants of full-arch metal-ceramic prostheses, during five years of follow-up. 558 implants (of three different brands) retaining 80 full-arch metal-ceramic prostheses were placed in 65 patients, all of whom were examined annually for biological and mechanical-technical complications during the five years of follow-up. Descriptive statistics and univariate logistic regression were calculated. The cumulative survival rate of the implants was 99.8%, and 98.8% prosthesis-based. Mucositis was the most frequent of the biological complications and peri-implantitis was recorded as 13.8% at restoration-level, 16.9% at patient level and 2.0% at implant level. An implant length greater than 10 mm was shown to be a protective factor against biological complications. The mechanical-technical complications were associated with implant diameter, abutment/implant connection and retention system. Loss of screw access filling was the most frequent prosthetic complication, followed by the fracture of the porcelain. Full-arch metal-ceramic prostheses show a high prevalence of implant and prosthesis survival, with few biological and mechanical-technical complications.

Abstract
PURPOSE To determine the prevalence and distribution of prosthetic complications affecting implant-supported fixed dental prostheses (ISFDPs). MATERIALS AND METHODS Subjects previously treated with one or more ISFDP(s) were identified from an electronic health record search and recalled for comprehensive clinical examination. Past prosthesis failures and complications were identified from the patient records while any existing complications, not previously recorded, were assessed during examination. ISFDP survival and failure rates were calculated with Kaplan-Meier curves and life table analysis, while regression Poisson analysis was used to identify associations between outcomes and possible patient- and prosthesis-based risk factors. RESULTS Seventy-four subjects with 107 ISFDPs were enrolled in the study with a mean time between prosthesis delivery and exam of 3.14 years (range: 1.00-9.00 years). Four prostheses failed, resulting in a cumulative prosthesis survival rate of 96.26%. Prosthetic complications affected 48.59% of ISFDPs, the majority (94.87%) of them minor complications. Only the use of a nightguard was associated with a lower prevalence of prosthetic screw loosening (HR 0.11, 95% CI 0.02-0.59, p = 0.007) while no outcome differences were noted for other variables. Patient satisfaction was high regardless of presence or number of complications. CONCLUSIONS ISFDPs demonstrated a high survival rate and overall high, patient-reported satisfaction. Minor prosthetic complications were common but were only significantly associated with nightguard use.

Abstract
In implant-supported prostheses, the most frequently reported mechanical complications after implant restoration are loosening or fracture of abutments or screws. Such complications have serious consequences, and removal of fractured abutments or screws is difficult. There are various methods to remove fractured abutment screws in implants with screwed-in connections. However, no approach has been reported to retrieve solid abutments in implants with a locking-taper implant-abutment connection, which are rarely observed in clinical settings. This study presents the case of a 62-year-old male patient with a fractured abutment in an upper-right second premolar implant. Abutment fracture is a common mechanical complication after dental implantation. Parafunctional habits and occlusal overloading may generate excessive occlusal forces, which increase the risk of mechanical complications. This report presents a series of emergency procedures for removing a fractured solid abutment and fabricating a new prosthesis to restore the edentulous area. In this retrospective analysis, the authors deeply consider the whole treatment, through which the deficiencies of the treatment are noted, and corresponding future directions are discussed. This case report presents a convenient approach to removing a solid abutment in a sudden emergency, discusses possible reasons for solid abutment fractures, designs a new rescue kit for easy retrieval of such abutments and summarizes a valid solution for removing fractured solid abutments.

Abstract
The objective of this study was to compare the efficacy of supportive periodontal therapy (i.e. scaling and root planning, SRP) alone, versus a chemical device silica dioxide (SiO2) colloidal solutions (SDCS) used in association with SRP in the treatment of chronic periodontitis in adult patients.
A total of 20 patients with a diagnosis of chronic periodontitis (40 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients have previously received any surgical or non-surgical periodontal therapy and demonstrated radiographic evidence of moderate bone loss. Two non-adjacent sites in separate quadrants were selected in each patient to monitor treatment efficacy (split mouth design). Clinical pocket depth (PD) and microbial analysis (MA) were analyzed at baseline day 15. SPSS program and paired simple statistic T-test were used to detect significant differences.
Total bacteria loading, Tannerella forsitia and Treponema denticola loading were statistically reduced when SiO2 is locally delivered. SDCS gel is an adjuvant therapy which should be added to SRP in the management of moderate to severe chronic periodontitis.

Abstract
BACKGROUND The influence of surgical approach on risk of early postoperative mechanical complications after total hip arthroplasty (THA) continues to be a focus of debate. We performed the first single-institution study on risk of early operative and nonoperative mechanical complications after THA based on approach, with the hypothesis that there would be no clinically significant difference with modern surgical methods. METHODS A retrospective study was conducted on 16,186 consecutive THA performed from 2010 to 2016. Revision or conversion THA and cases performed for hip fracture, with recalled prostheses, or during a surgeon's learning period were excluded. THAs were performed using direct anterior (DA; n = 5465), direct lateral (DL; n = 8561), or posterolateral approach with soft tissue repair (PL; n = 2160). All mechanical complications within the first 2 years were identified. The primary analysis was a time to event Cox regression, accounting for both patient and surgeon characteristics. RESULTS Compared with the DL approach, risk of mechanical complications was higher for both DA and PL. Adjusted risk of instability within 2 years was 0.17%, 0.74%, and 1.74% for DL, DA, and PL, respectively. While occurring at similar rates with the PL and DL approaches, the risk of periprosthetic fracture and loosening increased with DA. Consequently, femoral failure, including fracture or loosening, occurred more frequently for DA, with an adjusted incidence of 1.20% vs 0.58% and 0.47%, with DL and PL. CONCLUSION Even with soft tissue repair, instability continues to occur with increased frequency with the PL approach. While reducing dislocation, a higher risk of femoral failure with DA must also be considered. Nevertheless, the DL approach appears to confer the lowest overall risk of mechanical complications.

Abstract
BACKGROUND Central venous catheter (CVC) complication rates reflecting the application of modern insertion techniques to a clinically heterogeneous patient populations are needed to better understand procedural risk attributable to the 3 common anatomic insertion sites: internal jugular, subclavian, and femoral veins. We sought to define site-specific mechanical and duration-associated CVC complication rates across all hospital inpatients. METHODS A retrospective chart review was conducted over 9 months at Georgetown University Hospital and Washington Hospital Center. Peripherally inserted central catheters and tunneled or fluoroscopically placed CVC's were excluded. Mechanical complications (retained guidewire, arterial injury, and pneumothorax) and duration-associated complications (deep vein thrombosis or pulmonary embolism, and central line-associated bloodstream infections) were identified. RESULTS In all, 1179 CVC insertions in 801 adult patients were analyzed. Approximately 32% of patients had multiple lines placed. Of 1179 CVCs, 73 total complications were recorded, giving a total rate of one or more complications occurring per CVC of 5.9%. There was no statistically significant difference between site-specific complications. A total of 19 mechanical complications were documented, with a 1.5% complication rate of one or more mechanical complications occurring. A total of 54 delayed complications were documented, with a 4.4% complication rate of 1 or more delayed complications occurring. There were no statistically significant differences between anatomic sites for either total mechanical or total delayed complications. CONCLUSIONS These results suggest that site-specific CVC complication rates may be less common than previously reported. These data further inform on the safety of modern CVC insertion techniques across all patient populations and clinical settings.

Abstract
The use of LOCATOR® attachments in implant-supported removable dental prostheses (ISRDPs) has been evidenced with conflicting clinical behavior in literature. This retrospective study aimed to investigate the long-term clinical performance of LOCATOR® attachments by evaluating the frequency of the encountered mechanical complication events (MCEs) and the factors that play a role in attachment wear (AW). The study recruited participants with ISRDPs on LOCATOR® attachments. Clinical parameters, number of MCEs (attachment replacements, attachment loosenings, denture cap-related events, loss of retention and/or insert, and implant fractures), and AW were recorded. Nonparametric tests were applied for statistical analyses (𝛼=0.05). Baseline demographics for the recruited 47 participants (mean age: 72.0 ± 9.0 years) revealed an implant survival rate of 94.9% (mean observation period: 54.8 months), average peri-implant probing depths, bleeding on probing scores, and plaque scores of 1.80 ± 1.50 mm, 0.70 ± 0.90, and 0.81 ± 0.90, respectively. MCEs were directly influenced by the time in use (p < 0.001). The most frequently encountered MCEs were loss of retention (p < 0.001) and denture cap-related complications (p = 0.004). AW was found to be significantly higher in the maxilla than in the mandible (p = 0.028); in the maxilla, the vestibular (p = 0.005) and mesial (p = 0.01) aspects were the most common wear sites. Maxillary implant overdentures revealed more vestibular AW (p = 0.013). In prostheses supported by >3 implants, vestibular (p = 0.046) and mesial (p = 0.032) AW were common. Lingual AW (p = 0.021) was observed more frequently when the support was <3 implants. Loss of retention and AW are the most common complications encountered with LOCATOR® attachments. Therefore, a modification in the attachment design along with an amelioration of the attachment surface may help decrease the maintenance needs and further enhance its clinical performance.

Abstract
OBJECTIVES To analyze the complications of dental implant treatment in a group of patients with bruxism in comparison with a matched group of non-bruxers. MATERIAL AND METHODS Patients being diagnosed as bruxers were identified within a group of patients consecutively treated with implant-supported prostheses at one specialist clinic, based on the most recent listed sign and symptoms of bruxism according to the International Classification of Sleep Disorders. A diagnostic grading system of "possible," "probable," and "definite" sleep or awake bruxism was used, according to a recent published international consensus. A case-control matching model was used to match the bruxers with a group of non-bruxers, based on five variables. Implant-, prosthetic-, and patient-related data were collected, as well as 14 mechanical complications, and compared between groups. RESULTS Ninety-eight of 2670 patients were identified as bruxers. The odds ratio of implant failure in bruxers in relation to non-bruxers was 2.71 (95% CI 1.25, 5.88). Considering the same number of patients with the same total number of implants equally distributed between groups, the bruxers group had a higher prevalence of mechanical complications in comparison with the non-bruxers group. CONCLUSIONS This study suggests that bruxism may significantly increase both the implant failure rate and the rate of mechanical and technical complications of implant-supported restorations. Other risk factors may also have influenced the results.

Abstract
Ventricular septal rupture is a potentially fatal complication of acute myocardial infarction. The key to management of this critical condition is an aggressive approach to haemodynamic stabilization and surgical closure of the rupture. Where there is a small rupture and the patient is in a haemodynamically stable condition, surgery can be delayed with the prospect of achieving better perioperative results. However, in unstable critically ill patients either immediate surgery or extracorporeal membranous oxygenation support and delayed surgery is indicated. In some patients, trans-catheter closure may be considered as an alternative to surgery.

Abstract
Mechanical complications of ventricular assist devices (VADs) are rare but serious. The authors describe two cases of different mechanical complications of VADs that can affect the mitral valve. Attention should be paid to the position of the inflow/outflow cannula after off-loading of the ventricle, especially in acute heart failure and normal atrial dimensions. Complete off-loading of the left ventricle in the presence of a bioprosthetic mitral valve might cause fusion of the valve leaflets leading to mitral stenosis, which will call for another intervention.

Abstract
BACKGROUND This retrospective study was conducted to evaluate the effect of a new, modified open surgery technique on catheter-related malfunction. METHODS During the period from January 1997 to June 2009, 216 patients received initial peritoneal catheters. For the present study, patients were divided into four groups according to the catheter types and the surgery techniques: TO-S: traditional open surgery, straight Tenckhoff catheter TO-C: traditional open surgery, coiled Tenckhoff catheter TO-SN: traditional open surgery, swan-neck catheter MO-S: modified open surgery, straight Tenckhoff catheter The modified surgery was characterized by a low incision site, a short intra-abdominal catheter segment and an additional upward straight subcutaneous tunnel. All patients were followed up for 2 years or until death. Survival rates, complications caused by catheter placement, and the probability of malfunction-free catheter survival were compared between the groups. RESULTS Catheter malfunction was the most frequent mechanical complication, found in 31 patients (14.4%), who experienced 38 malfunctions. Only 2 episodes of catheter malfunction were found in the MO-S group, representing a rate significantly less than those in the TO-S and TO-C groups (both p < 0.05). Kaplan-Meier curves for malfunction-free PD catheter survival showed a significantly different malfunction-free probability for the various groups (p = 0.009). After 2 years of follow-up, 136 patients (63.0%) survived with their initial PD catheter. The initial catheter survival rate was 76.8% in the MO-S group. Kaplan-Meier curves for initial catheter survival showed that the highest survival rate was found in the MO-S group (p = 0.001). CONCLUSIONS The modified open surgery technique is a reliable method for catheter placement.

Abstract
PURPOSE The aim of this 10-year follow-up study was to evaluate the implant survival and complication rates of fixed restorations supported by locking-taper implants. MATERIALS AND METHODS Over a 10-year period (January 2002 to December 2011) all patients referred to a single private practice for treatment with fixed restorations (single crowns, SCs; fixed partial prostheses, FPPs; fixed full arches, FFAs) supported by dental implants were considered for inclusion in the study. At each annual follow-up session, clinical, radiographic, and prosthetic parameters were assessed. The surviving implant-supported restorations were defined as "complication free" in the absence of any biological or prosthetic (mechanical or technical) complication. The cumulative implant survival and the "complication-free" survival of fixed implant-supported restorations were identified using the Kaplan-Meier method. The Log-rank test was used to identify correlations between the study variables. RESULTS In total, 1494 locking-taper implants (727 maxilla, 767 mandible) were placed in 642 patients (356 males, 286 females). Nineteen implants (12 maxilla, 7 mandible) failed. Implant failures were attributed to lack of osseointegration (14 implants), peri-implantitis (4 implants), and mechanical overloading (1 implant). An overall 10-year cumulative implant survival rate of 98.7% (98.3% maxilla, 99.1% mandible) was found. The implant survival rates did not significantly differ with respect to implant location, position, bone type, implant length and diameter, and type of restorations. Among the surviving implant-supported restorations (478 SC, 242 FPP, 19 FFA), a few biological (11/739: 1.4%) and prosthetic (27/739: 3.6%) complications were reported. The incidence of mechanical complications was low (3/739: 0.4%), with three loosened abutments in three SCs (3/478: 0.6%), and no abutment fractures; technical complications were more frequent (24/739: 3.2%), with an incidence of decementation of 2.0% (SC 2.0%, FPP 1.6%, FFA 5.2%) and ceramic/veneer chipping/fracture of 1.2% (SC 0.0%, FPP 2.8%, FFA 10.5%). A 10-year cumulative "complication-free" survival of restorations of 88.6% (SC 91.7%, FPP 83.1%, FFA 73.8%) was reported. The complication rates differ significantly with respect to the type of restoration (p < 0.05). CONCLUSIONS Fixed restorations on locking-taper implants seem to be a successful procedure for the rehabilitation of partially and completely edentulous arches.

Abstract
Background: Central venous catheters (CVC) are associated with mechanical, infectious and thrombotic complications. Aims: To study (a) the incidence of mechanical and infectious complications of CVC insertions and to compare, (b) the rates of these complications between the internal jugular venous (IJV) and the subclavian venous (SCV) accesses. Settings and Design: An adult intensive care unit of a tertiary care hospital. Prospective, observational study. Methods: All landmark-based CVC insertions performed between 1st October 2008 and 30th September 2009 were prospectively studied for mechanical and infectious complications. Statistical Analysis: SPSS software for Windows, Version SPSS 16.0, and Epi Info (3.5.1) software. Results: Four hundred and eighty central venous catheterizations were studied (IJV route, 241 and SCV route, 239). Mechanical complications occurred in 86 patients (17.9%, bleeding complications-48, catheter-related complications-27 and pneumothorax-11). The IJV route was associated with a significantly higher incidence of bleeding complications (P=0.009). Forty-seven patients had infectious complications (9.79%), like exit site infections (n=17), catheter tip infections (n=22) and catheter-related bloodstream infections (CRBSIs) (n=8). The risks of infectious complications increased significantly if the CVC was in situ for longer than 7 days (P=0.009), especially with IJV cannulae. The incidence density of CVC tip infections was 7.67 per 1000 catheter days and of CRBSIs was 2.79 per 1000 catheter days. Conclusions: Bleeding complications occurred more frequently with IJV insertions and infectious complications occurred more commonly in cannulae that were left in situ for longer than 7 days.

Abstract
Cardiogenic shock is often a devastating consequence of acute myocardial infarction (MI) and portends to significant mortality and morbidity. Despite improvements in expediting the time to treatment and enhancements in available medical therapy and reperfusion techniques, cardiogenic shock remains the most common cause of mortality following MI. Post-MI cardiogenic shock most commonly occurs as a consequence of severe left ventricular dysfunction. Right ventricular (RV) MI must also be considered. Mechanical complications including acute mitral regurgitation, ventricular septal rupture, and ventricular free-wall rupture can also lead to cardiogenic shock. Rapid diagnosis of cardiogenic shock and its underlying cause is pivotal to delivering definitive therapy. Intravenous vasoactive agents and mechanical support devices may temporize the patient's hemodynamic status until definitive therapy by percutaneous or surgical intervention can be performed. Despite prompt management, post-MI cardiogenic shock mortality remains high.
