Lower limb post-traumatic osteomyelitis: a systematic review of clinical outcomes

PurposeThe aim of this study was to examine the patient-reported outcomes of patients presenting with post-traumatic osteomyelitis (PTOM) of the lower limb over the past 15 years. This period was chosen to reflect modern treatment principles and increased centralisation of care.MethodsAn electronic literature search of the relevant databases (PubMed, Ovid Medline, Embase, and the Cochrane library) was conducted to identify studies published between January 2006 and July 2021 reporting series of greater than 10 patients with PTOM of the tibia or femur at the site of a previous fracture. Studies reporting septic non-union were excluded.ResultsSixteen eligible studies were identified and included in the final report. Remission of infection was achieved in 93.2% of cases (range 70–100%), whilst amputation was reported in 1–7% of cases. A variety of patient-reported outcome measures were utilised including the lower extremity functional scale, short musculoskeletal functional assessment, Enneking score, and EQ-5D-3L. Limb-specific functional outcomes returned to levels similar to that of the general population although poorer outcomes were noted in specific cohorts including those with complex anatomic disease and active medical comorbidities.ConclusionInfection following fracture fixation remains a difficult problem to treat. Regardless, using modern treatments and techniques patients can have comparable functional outcomes to that of the general population. High-quality studies are required to advance our knowledge into which types of treatments offer a benefit and how to further improve outcomes.

A Systematic Review of Clinical Outcomes from Pharmacist Provided Medication Therapy Management (MTM) among Patients with Diabetes, Hypertension, or Dyslipidemia.

This study aimed to compare the clinical outcomes of pharmacist-provided medication therapy management (MTM) services as compared to no MTM services (i.e., standard of care) on outpatient clinical outcomes for patients with diabetes, hypertension, or dyslipidemia. A systematic literature review of PubMed, EMBASE, Cochrane library, International Pharmaceutical s, PsycINFO, Scopus, CINAHL electronic databases, grey literature, websites, and journals, was conducted from 1 January 2005–20 July 2021. The search field contained a combination of keywords and MeSH terms such as: “medication therapy management”, “pharmacist”, “treatment outcomes”. Studies published in United States, included adults ≥18 years old who received at least one pharmacist-provided MTM consultation and at least one group who received no MTM, and reported pre-specified clinical outcomes for diabetes mellitus, hypertension, or dyslipidemia were included. Of 849 studies identified, eight were included (cohort studies = 6, randomized controlled trials = 2). Clinical outcomes improved with MTM interventions, as evidenced by statistically significant changes in at least one of the three chronic conditions in most studies. Improvements were observed for diabetes outcomes (n = 4 studies), hypertension outcomes (n = 4 studies), and dyslipidemia outcomes (n = 3 studies). Overall, this study indicated that pharmacist delivered MTM services (versus no MTM services) can improve clinical outcomes for patients with diabetes, hypertension, and dyslipidemia.

EP.FRI.36 Clinical outcomes for surgical management of unstable spinal fractures in polytrauma patients: A systematic review

Abstract Aims This systematic review seeks to identify and discuss clinical outcomes in polytrauma patients who undergo surgical fixation of unstable spinal fractures. Specifically, this review aims to address the question of whether one surgical treatment modality outperforms other surgical approaches. Methods PubMed and the Cochrane Library database were systematically searched for case reports and clinical studies using key words and MeSH terms. Titles and abstracts were skimmed, and relevant articles were identified for further analysis. A total of 96 results were returned, 16 of which were included for full-text review. Results Six articles met the inclusion criteria. Four case reports, one case series, and one retrospective study published variable datasets, and each article failed to include highly relevant information. Thus, while conclusive statements about clinical outcomes in this population cannot be made, specific recommendations for future publications can. Conclusion Limited studies, a small overall cohort, and inconsistent reporting of data preclude a comprehensive systematic review of clinical outcomes. However, this review serves to highlight the need for consistent and standardized reporting guidelines for this cohort. In addition, two cases were successfully treated with minimally invasive techniques, suggesting that viable surgical options exist for patients who cannot undergo open spine surgery. Finally, these data support early surgical intervention when medically possible.

204 A Systematic Review of Clinical Outcomes for Outpatient vs Inpatient Shoulder Arthroplasty

Abstract Aim Outpatient shoulder arthroplasty is growing in popularity as a cost-effective and potentially equally safe alternative to inpatient arthroplasty. We investigated literature relating to outpatient shoulder arthroplasty, looking at clinical outcomes, complications, readmission, and cost compared to inpatient arthroplasty. Method We systematically searched Medline, Embase, PubMed using relevant search terms. Methodological quality of included studies was assessed using Methodological Index for Non-Randomised Studies score. Results We included 17 studies in our review with 11 included in the meta-analyses. A meta-analysis of hospital readmissions demonstrated that there was no statistically significant difference between outpatient and inpatient cohorts (OR = 0.89, 95% CI: 0.63-1.25, p = 0.49, I2=56%). Pooling results for all post-operative complications identified decreased complications in those undergoing outpatient surgery (OR = 0.70; 95% CI: 0.52-0.94, p = 0.02, I2=50%). No statistically significant difference was identified with respect to medical complications (OR = 0.86, 95% CI: 0.74-1.01, p = 0.07, I2=0%) or surgical complications (OR = 0.71, 95% CI: 0.45-1.12, p = 0.14, I2=26%). Considerable cost saving of between $3 614 – $53 202 (19.7 – 69.9%) per patient were present in the outpatient setting. Conclusions Shoulder arthroplasty in the outpatient setting is as safe as shoulder arthroplasty in the inpatient setting, with a significant reduction in cost. There is no demonstrable statistically significant difference with regards to readmissions between outpatient and inpatient shoulder arthroplasty. In the appropriately selected patient, outpatient shoulder arthroplasty is safe and cost-effective; however, we still need to work towards understanding who the appropriate patients are for this post-operative care pathway.

Fourth-Generation Total Wrist Arthroplasty: A Systematic Review of Clinical Outcomes.

Background The purpose of total wrist arthroplasty is to reduce pain and maintain mobility in a painful destructed wrist. First-, second-, and third-generation total wrist arthroplasties have shown unacceptable outcomes with high failure rates. In 2004, the fourth-generation total wrist implants were introduced to address the clinical problems encountered in the previous generations of total wrist implants. Methods Outcomes and complications of fourth-generation total wrist implants were systematically reviewed in the literature (2004-present), including the Universal 2, ReMotion, Freedom, Motec, and Maestro total wrist implants. Results The literature search yielded 114 papers, of which 18 (990 implants) were included in this systematic review. The quality of evidence was low. All implants effectively reduced pain and improved functionality of the wrist. The Motec wrist implant demonstrated the highest survival rate at 10 year follow-up (86%). Conclusion This systematic review suggests a substantial improvement of quality in fourth-generation total wrist arthroplasty.

Immune-Checkpoint Inhibitors for Metastatic Colorectal Cancer: A Systematic Review of Clinical Outcomes.

Simple SummaryIn 2018, colorectal cancer (CRC) was declared the fourth most deadly cancer worldwide. Unfortunately, a quarter of all patients are diagnosed at late stages, when curative surgery is not possible, rendering systemic therapy and/or best supportive care as the only options. To our knowledge, this is the first systematic review assessing response and survival rates in patients with mCRC treated with immune-checkpoint inhibitors (ICIs). Our study established that ICIs show potentially superior response rates in mCRC patients, though only in those with high microsatellite instability (MSI). Nivolumab + regorafenib was reported to provide encouraging response in low-MSI (MSI-L) patients; however, additional studies using cohort randomization are required. Further studies are required, particularly regarding the mechanism of resistance to ICIs in MSI-L patients.Background. Colorectal cancer (CRC) is the fourth most deadly cancer worldwide. Unfortunately, a quarter of the patients are diagnosed at late stages, when surgical options are limited. Targeted therapies, particularly immune-checkpoint inhibitors (ICIs), are the latest addition and have been studied herein regarding their efficacy outcomes. Methods. Clinical studies were identified through the PubMed, Scopus and Cochrane databases. Any trial that evaluated ICIs in patients with metastatic CRC (mCRC) and reported the objective response rate was deemed eligible. Data analysis was performed by employing the random-effects model in STATA v.17. Results. A total of 461 articles were identified; 13 clinical trials were included, encompassing a total cohort of 1209 patients. Our study determined that a single PD-1/PD-L1 checkpoint blockade provides durable clinical response in mCRC patients with high microsatellite instability (MSI-H). The combinatorial therapy of CTLA-4 + PD-1 inhibitors also showed high response rates in pre-treated MSI-H patients. The single-arm REGONIVO trial reported durable clinical response in patients with microsatellite stable (MSS) status. Conclusions. Our study surmises that PD-1/PD-L1 inhibitors as well as combination therapy with CTLA-4 and PD-1 inhibitors show encouraging response rates in mCRC patients, albeit exclusively in patients with cancer that are of MSI-H status. A single study suggests that nivolumab + regorafenib can reach a durable response rate in MSS patients; however, further studies in larger randomized settings are required.

A systematic review of clinical outcomes for outpatient vs. inpatient shoulder arthroplasty.

BackgroundOutpatient shoulder arthroplasty is growing in popularity as a cost-effective and potentially equally safe alternative to inpatient arthroplasty. The aim of this study was to investigate literature relating to outpatient shoulder arthroplasty, looking at clinical outcomes, complications, readmission, and cost compared to inpatient arthroplasty.MethodsWe conducted a systematic review of Medline, Embase and Cochrane Library databases from inception to 6 April 2020. Methodological quality was assessed using MINORS and GRADE criteria.ResultsWe included 17 studies, with 11 included in meta-analyses and 6 in narrative review. A meta-analysis of hospital readmissions demonstrated no statistically significant difference between outpatient and inpatient cohorts (OR = 0.89, p = 0.49). Pooled post-operative complications identified decreased complications in those undergoing outpatient surgery (OR = 0.70, p = 0.02). Considerable cost saving of between $3614 and $53,202 (19.7–69.9%) per patient were present in the outpatient setting. Overall study quality was low and presented a serious risk of bias.DiscussionShoulder arthroplasty in the outpatient setting appears to be as safe as shoulder arthroplasty in the inpatient setting, with a significant reduction in cost. However, this is based on low quality evidence and high risk of bias suggests further research is needed to substantiate these findings.

Renal sympathetic denervation for the treatment of recurrent ventricular arrhythmias-ELECTRAM investigators.

Renal sympathetic denervation (RSDN) is an alternate management approach for refractory ventricular arrhythmias (VAs). We aimed to perform a systematic review of clinical outcomes on the impact of RSDN on refractory VA patients. A systematic search without language restriction, using PubMed, EMBASE, SCOPUS, Google Scholar, and ClinicalTrials.gov from inception to August 18, 2020, was performed for the studies that reported outcomes in patients who underwent RSDN for VA. The outcomes studied were-(1) recurrent VA; and (2) all-cause mortality. Five studies (from 2014 to 2018) with a total of 51 VA patients met study inclusion criteria. The mean age was 61.92±11.76 years, and 78.4% were men. The pooled incidence of short-term (3 months or less) and long-term (more than 3 months) VA recurrence was 63.85% (95% CI 16.75 to 99.32) and 10.52% (95% CI 0.14 to 28.75), respectively. When stratified by the number of VA episodes, there was a significant reduction in mean VA episodes (SMD -3.79, 95% CI -6.59 to -0.98, p<.01), ICD shocks (SMD -1.71, 95% CI -3.0 to -0.42, p<.01) and anti-tachycardia pacing (SMD -1.21, 95% CI -1.98 to -0.44, p<.01) following RSDN denervation. The pooled incidence of all-cause mortality after RSDN was 10.16% (95% CI 1.08 to 24.12). There were no major vascular complications, one minor vascular complication-small non-flow limiting renal artery dissection (no intervention needed). RSDN appears to be a safe and effective treatment strategy in patients with prior failed antiarrhythmic drugs and catheter ablation for recurrent ventricular arrhythmia and electrical storm.

M15 Surgery for Type A Intramural Haematoma: A Systematic Review of Clinical Outcomes

Management of Type A intramural haematoma (IMH) remains controversial, with conflicting attitudes between early aggressive surgical management and adopting a conservative approach. The present systematic review aims to evaluate the mortality and morbidities following surgery for type A IMH.

Spontaneous Heterotopic Pregnancy with Unaffected Intrauterine Pregnancy: Systematic Review of Clinical Outcomes

Background and objective: Spontaneous heterotopic pregnancy (SHP) is a rare condition represented by the synchronous coexistence of an intrauterine and an ectopic pregnancy. It rarely occurs with natural conception and is usually a consequence of assisted reproductive techniques. Diagnosis of SHP can be a challenge for the clinician. The evolution of the intrauterine pregnancy is dependent on many factors, such as the location of the heterotopic pregnancy, gestational age at the time of diagnosis, the surgical procedure, the presence of other risk factors, early or delayed management. The aim of this systematic review of the literature was to extract existing evidence on spontaneous heterotopic pregnancy with otherwise unaffected intrauterine pregnancy. Materials and Methods: From a total of 1907 database entries identified in PubMed, EMBASE and Cochrane reviews, we selected 18 papers for narrative synthesis, for which we explored the diagnostic options, treatment, and outcome of these extremely rare epidemiologic occurrences. Manuscripts were assessed using the CARE guidelines for reporting case reports. Results: The main symptom was abdominal pain, and the preferred treatment approach was surgical, more precisely, using a laparoscopic approach. Most cases presented no risk factors, and the diagnosis was mostly made in the first semester. Conclusions: Normal follow-up and evolution of intrauterine pregnancy have been observed regardless of surgical approach (open or laparoscopic). Early diagnosis and treatment are advised, as they impact maternal and fetal outcomes. Evidence on this topic is scarce, predominantly comprised of case reports with variable degrees of adherence to dissemination guidelines. More studies on this topic are required to optimize care protocols for this type of pregnancy.

Subtalar Distraction Arthrodesis for the Treatment of Subtalar Arthritis and Severe Hindfoot Deformity: A Systematic Review

Category:Hindfoot; TraumaIntroduction/Purpose:Subtalar distraction arthrodesis (SDA) was developed as a means of treating the symptoms of subtalar arthritis. Despite almost 30 years of research in this field, many controversies still exist regarding SDA. The objectives of this study were (1) to conduct a systematic review of clinical outcomes following SDA, (2) to assess the demographics, indications, and surgical technique used, (3) to assess the clinical and radiographic outcomes of this procedure and its role in improving function,(4) to provide treatment recommendations based on the best available literature, and (5) to identify knowledge deficits that require further investigation.Methods:MEDLINE and EMBASE were queried with an end date of January 1, 2018 using the keywords The keywords used for this search included ‘‘subtalar,’’ ‘‘talar,’’ ‘‘talus,’’ ‘‘bone,’’ ‘‘block,’’ ‘distraction,’ ‘arthrodesis,’ ‘fusion,’ ‘arthritis,’ ‘arthrosis,’ ‘calcaneus,’ ‘calcaneal,’ ‘fracture,’ ‘malunion,’ ‘deformity,’ and ‘‘clinical outcome,’’ alone and in various combinations using the Boolean operator ‘‘AND.’’ Data abstraction was performed by two independent reviewers. Inclusion criteria for the articles were (1) English language, (2) peer-reviewed clinical studies with evidence levels I to IV, (3) with at least five patients, (4) reporting clinical and/or radiographic outcomes of SDA. Data collected included: demographics, operative techniques, radiographic measures, clinical and functional outcomes, and complications. The level of evidence for each study was assessed according to the method described by Wright et al. Methods followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.Results:Twenty-five studies matched the inclusion criteria (2 Level III and 23 Level IV studies) including 492 feet in 467 patients. The most common indication for SDA was late complications of calcaneus fractures. Many different operative techniques have been described, and there is no proven superiority of one method over the other. The most commonly reported complications were nonunion, hardware prominence, wound complications, and sural neuralgia. All studies showed both radiographic and clinical improvement at the last follow-up visit compared with the preoperative evaluation. Pooled results (12 studies, 237 patients) demonstrated improved American Orthopaedic Foot & Ankle Society ankle hindfoot scores with a weighted average of 33 points of improvement.Conclusion:Subtalar bone block arthrodesis provides good clinical results at short-term and midterm follow-up, with improvement in ankle function as well as acceptable complication and failure rates. These consistent clinical outcomes throughout the literature, despite different lengths of followup periods, suggest that the functional results do not deteriorate with time.Higher confidence recommendations for SDA require longer follow-up, clear indications and treatment protocols, standardized clinical and radiographic outcome measures, and direct comparison or stratification of results based on graft type and other operative techniques.

Systematic review of clinical outcomes of clinical pharmacist roles in hospitalised general medicine patients

AbstractAimThe role of clinical pharmacists in the care of hospitalised general medicine patients is evolving from a reactive model of care to a model with an emphasis on interdisciplinary care and more advanced models of care. The purpose of this review was to evaluate the published literature on the effects of roles of clinical pharmacists that extend beyond those activities considered to be standard clinical practice in Australia, on clinical outcomes in hospitalised general medicine patients.Data sourcesA search of English‐language publications in six databases was conducted.Study selectionPeer‐reviewed, English‐language articles were identified across the date range January 2000 to June 2020. Studies were included if they evaluated an inpatient pharmacy service in a general medicine population and the article included a study design with a clear comparator and outcomes such as medication errors or medication appropriateness. Studies evaluating pharmacists’ activities that are considered standard clinical practice for pharmacists in Australia, such as participation on ward rounds, medication reconciliation and patient education were excluded.ResultsTwelve studies met the inclusion criteria: four evaluating pharmacist‐led anticoagulation or thromboprophylaxis management, one evaluating pharmacist‐led vaccination, three evaluating a pharmacist charting model, two evaluating pharmacist‐led de‐escalation of therapy, one evaluating a pharmacist intervention in patients with chronic kidney disease and one evaluating pharmacist‐led glycaemic control.ConclusionsThe addition of advanced clinical pharmacist services in the care of general medicine inpatients generally resulted in improved care, with no evidence of harm. Future studies should include multiple sites, larger sample sizes, reproducible interventions and identification of patient‐specific factors that lead to improved outcomes.

Bilateral total shoulder arthroplasty: A systematic review of clinical outcomes.

The purpose of this study was to describe the clinical outcomes following bilateral total shoulder arthroplasty (TSA). A systematic search of the PubMed, Embase, and Cochrane Library databases following PRISMA guidelines was performed. English-language literature published from 2010 to 2018 analyzing bilateral TSA (anatomic and/or reverse) with a minimum one-year follow-up was reviewed by two independent reviewers. Study quality was evaluated with the Modified Coleman Methodology Score and the methodological index for non-randomized studies score. Eleven studies (1 Level II, 3 Level III, 7 Level IV) with 292 patients were included. Two studies reported on bilateral anatomic TSA (n = 54), six reported on bilateral reverse TSA (RTSA; n = 168), two reported on anatomic TSA with contralateral RTSA (TSA/RTSA; n = 31), and one compared bilateral anatomic TSA (n = 26) and bilateral RTSA (n = 13). Among studies, mean revision rate ranged from 0% to 10.53% and mean complication rate ranged from 4.9% to 31.3%. At final follow-up, patients experienced significant overall improvements in range of motion and patient-reported outcome score measurements. However, bilateral anatomic TSA resulted in greater improvements in external rotation compared to bilateral RTSA. Overall patient satisfaction was 91.0%. The available data indicate that bilateral TSA allows for functional and pain improvements and result in high patient satisfaction. IV.

Treatment of elbow periprosthetic joint infection: a systematic review of clinical outcomes

Periprosthetic joint infection (PJI) of the elbow is a relatively common complication after total elbow arthroplasty (TEA), and its treatment is frequently variable. Few articles have provided direct comparisons of outcomes, making it difficult to draw conclusions from the available literature. This systematic review synthesizes the English-language literature on elbow PJI to quantify treatment outcomes. The PubMed and Scopus databases were searched in December 2018. Our review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Keywords included "elbow replacement infection" and "elbow arthroplasty infection." A total of 1056 titles were identified; after application of the exclusion criteria, 41 studies met the screening criteria and underwent full-text review. Fifteen articles were included for the final analysis regarding demographic characteristics, risk factors, infecting organisms, success of eradication of infection based on surgical method, and functional outcomes of specific treatment regimens. Among the 15 articles selected, there were 309 TEA infections. Staphylococcus aureus was the most frequently isolated organism (42.4%), followed by coagulase-negative staphylococci (32.6%). Risk factors for the development of elbow PJI included rheumatoid arthritis, steroid use, an immunocompromised state, and previous elbow surgery. The rate of successful infection eradication was highest with 2-stage revision (81.2%) and lowest with irrigation and débridement for component retention (55.8%). The level of evidence was IV in 14 studies and III in 1 study. In this systematic review of TEA infections, Staphylococcus species represent the most common infecting organism. Two-stage revision was the most effective treatment for elbow PJI, showing the lowest recurrence rate for infection.

Primary Linked Total Elbow Arthroplasty for Acute Distal Humerus Fracture Management: A Systematic Review of Clinical Outcome.

BackgroudThe treatment of distal humerus fractures is often challenging in osteoporotic elderly patients. Total elbow arthroplasty (TEA) is a salvage option for non-reconstructable fractures. The aim of this systematic review was to evaluate the clinical evidence for primary TEA in patients with acute distal humeral fractures.MethodsLiteratures were searched through PubMed, Ovid/Medline, Cochrane, Google Scholar, and Embase databases with the keywords, “distal humerus fracture,” “total elbow arthroplasty,” and “outcome” according to the MeSH (Medical Subject Headings) index for English-language studies published from April 2009 to April 2019. We performed a systematic review using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines.ResultsTen articles with a total of 269 patients were included in the review. The Bryan-Morrey approach was the most common surgical approach (33.7%) with triceps reflecting (42%) for triceps tendon management. The most common implant design used was the Coonrad-Morrey system (83%). The mean postoperative motion arc was 102.3° for flexion-extension and 145.8° for pronation-supination. The average functional outcome score was 89.5 with Mayo Elbow Performance Score (MEPS). An excellent MEPS was found in studies with less than 7 days of average time from injury to surgery. The overall complication rate was 21.5%.ConclusionsThe current review showed favorable outcome of primary linked TEA for acute distal humerus fractures. Despite the promising functional outcomes, the complication rate was still considerably high. This systematic review will give surgeons help in explaining to patients regarding the expected outcome after primary TEA for acute distal humerus fractures.

Improved Dysphagia Outcomes in Anchored Spacers Versus Plate-Screw Systems in Anterior Cervical Discectomy and Fusion: A Systematic Review.

Study Design:Systematic review and meta-analysis.Objective:To perform a systematic review of clinical outcomes between stand-alone anchored spacers and traditional cages with plate fixation for dysphagia and pseudoarthrosis using data from clinical trials.Methods:Our search protocol was added to PROSPERO register and systematic review using PRISMA method was performed. Then, we systematically searched for studies addressing stand-alone anchored spacers in patients who underwent ACDF. Mean Neck Disability Index (NDI), dysphagia incidence % (Dinc%), and Swallowing–Quality of Life (SQOL) scores during preoperative, immediate postoperative and last follow-up visits were extracted. Chi-square and analysis of variance (ANOVA) tests were used for statistical comparisons (P ≤ .05).Results:The initial search generated 506 articles in CENTRAL and 40 articles in MEDLINE. Finally, 14 articles were included. Total number of patients was 1173 (583 anchored stand-alone and 590 plate). Dinc% scores were statistically significantly lower in the stand-alone anchored spacer compared to the plate-screw construct (P ≤ .05). ANOVA showed no statistically significant difference in the comparisons of SQOL. On the other hand, NDI scores were statistically significantly lower in baseline of stand-alone anchored spacer and the plate-screw construct compared with both immediate postoperative and last follow-up visits (P ≤ .05).Conclusions:Our study results revealed that the stand-alone anchored spacers were associated with less dysphagia in the immediate and last follow-up.

A Systematic Review of Clinical Outcomes Associated With Intrahospital Transitions.

Previous transitional care research has focused on transitions occurring between community and hospital settings. Little is known regarding intrahospital transitions and how they affect care quality. A systematic review was therefore conducted to synthesize the literature regarding clinical outcomes associated with intrahospital transitions. Literature published between January 2003 and December 2018 and indexed in Medline/PubMed, CINAHL, and PsychINFO were reviewed using PRISMA guidelines. Articles were limited to English language and peer-reviewed. Articles were excluded if they focused on transitions occurring from or to the hospital, discharge/discharge planning, or postdischarge follow-up. Data abstraction included study characteristics, sample characteristics, and reported clinical outcomes. Fourteen studies met inclusion criteria, primarily using cross-sectional, cohort, or retrospective chart review quantitative designs. Data were analyzed and synthesized based on outcomes reported. Major outcomes emerging from the articles included delirium, hospital length of stay, mortality, and adverse events. Delirium, hospital length of stay, and morbidity and mortality rates were associated with delayed transfers and transfers to inappropriate units. In addition, increased fall risk and infection rates were associated with higher rates of transfer. Intrahospital transitions represent critical periods of time where the quality of care being provided may be diminished, negatively affecting patient safety and outcomes.

New Perspectives of Osteochondral Lesion of the Talus

Osteochondral lesions of the talus(OLT) are the most common articular cartilage defects in the ankle and may cause disability as a result of chronic pain and limited weight-bearing capacity. Numerous treatment strategies for symptomatic OLT have advanced significantly over the past decades.OLT are often managed conservatively for an initial stage before the surgical treatment. However, the conservative management determined solely on symptomatology, and not on the physiological healing. A systematic review for the treatment of OLT demonstrated a 45% success rate of non-operative management. Surgical treatment of OLT is reserved for symptomatic focal lesions that fail to respond to conservative treatments. There are three major operative strategies for OLT, reparative, replacement and regenerative manners.For the reparative modality, arthroscopic bone marrow stimulation(BMS) is widely regarded as the first-line treatment for OLT, as it is a technically undemanding, cost-effective, and minimally invasive procedure with low rates of complication and postoperative pain. Small lesion (<15 mm in diameter or <150mm2 in size) is the ideal candidate for BMS supported by several literatures. And a study reported the long-term follow-up study to date at 8-20 years after BMS in which 78% of patients had an excellent or good functional outcome score.As a replacement strategy, autologous osteochondral transplantation(AOT) is often indicated for symptomatic large, cystic lesions, including those that have failed previous reparative procedures, such as BMS. Osteochondral autograft transfer carries the inherent advantage over osteochondral allograft of being from the host with fresh viable cartilage, most commonly harvested from the ipsilateral knee. Clinical studies have found favorable results with osteochondral autograft techniques, including a recent systematic review of clinical outcomes at mid-term follow-up demonstrating excellent or good outcomes in 87% of patients.In recent years, Scaffold-based regenerative techniques are getting more attention. Matrix-associated chondrocyte implantation(MACI) is a 2-step procedure in which culture-expanded autologous chondrocytes are seeded on a scaffold, which is then secured in the OLT. More recently, 1-step procedures have been developed in which scaffolds and/or orthobiologics, including bone marrow aspirate concentrate(BMAC) and platelet-rich plasma(PRP), and hyaluronic acid(HA) have been used to augment microfracture with the intention of overcoming the 2-step procedures while concurrently promoting chondrogenic differentiation of endogenous stem cells. Matrix-augmented BMS is one such technique that has been reported with good results in case series.In the future, an advanced strategy for tissue engineering with gene therapy may influence the quality of integration and longevity in treatment of OLT.

A Systematic Review of Clinical Outcomes on Patients Rehabilitated with Complete-Arch Fixed Implant-Supported Prostheses According to the Time of Loading.

To perform a systematic review on studies assessing clinical outcomes in patients rehabilitated with complete-arch fixed implant-supported prostheses according to the time of loading. Data obtained from patient and clinical outcomes, as implant failure, success rate, survival rate, biological complications, technical complications, mechanical complications, and marginal bone loss, were included on this review. The search was performed on databases PubMed, Scopus, and Cochrane. Cochrane Collaboration tool was used to assess the risk of bias of randomized controlled studies, and an adapted version of Newcastle-Ottawa scale was used for observational studies. All data were tabulated according to the time of loading: (1) immediate restoration/loading, (2) early loading, and (3) conventional loading. From a total of 4027 studies identified through the three databases, six of them were randomized controlled trials, five of them were prospective observational studies, and another five were retrospective observational studies. In total, 5954 implants, 1294 patients and 1305 full-arch fixed implant-supported prostheses were included in this review. There was a wide heterogeneity among clinical studies regarding the study design and treatment procedures. Thus, pooled estimates were not performed in order to avoid potential biases. The methodological assessment by the Modified Newcastle-Ottawa scale showed a moderate quality of observational studies. Regarding the RCTs studies, all of them presented at least one element of bias according to the Cochrane Collaboration tool for assessing risk of bias. There is evidence of high survival-success implant rate (95-100%) for either loading protocols (immediate restoration/loading, early loading, and conventional loading). However, careful attention must be taken by clinician when interpreting the results reported in clinical studies. Future studies should be performed using standardized methodology in order to determine the true predictability regarding immediate, early, and conventional loading protocols.
