Perioperative Systemic Dexamethasone Reduces Length of Stay in Total Joint Arthroplasty: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BackgroundThe objective of this review is to examine the effect of perioperative systemic corticosteroids at varying doses and timings on early postoperative recovery outcomes following unilateral total knee and total hip arthroplasty. The primary outcome was length of stay (LOS).MethodsA systematic review and meta-analysis of randomized controlled trials was performed. MEDLINE, EMBASE, and Cochrane Library databases were searched from inception to June 1, 2020. Studies comparing the outcome of adult patients receiving a systemic steroid to patients who did not receive steroids were included.ResultsSeventeen studies were included, incorporating 1957 patients. Perioperative corticosteroids reduced hospital LOS (mean difference [MD] = ?0.39 days, 95% confidence interval [CI] ?0.61 to ?0.18). A subsequent dose of corticosteroid at 24 hours further reduced LOS (MD = ?0.33, 95% CI ?0.55 to ?0.11). Corticosteroids resulted in reduced levels of pain on postoperative day (POD) 0 (MD = ?1.99, 95% CI ?3.30 to ?0.69), POD1 (MD = ?1.47, 95% CI ?2.15 to ?0.79), and POD2. Higher doses were more effective in reducing pain with activity on POD0 (P = .006) and 1 (P = .023). Steroids reduced the incidence of PONV on POD1 (log odds ratio [OR] = ?1.05, 95% CI ?1.26 to ?0.84) and POD2, with greater effect at higher doses (P = .046). Corticosteroids did not increase the incidence of infection (P = 1.000), venous thromboembolism (P = 1.000), or gastrointestinal hemorrhage (P = 1.000) but were associated with an increase in blood glucose (MD = 5.30 mg/dL, 95% CI 2.69-7.90).ConclusionPerioperative corticosteroids are safe, facilitate earlier discharge, and improve patient recovery following unilateral total knee arthroplasty and total hip arthroplasty. Higher doses (15-20 mg of dexamethasone) are associated with further reductions in dynamic pain and PONV, and repeat dosing may further reduce LOS.     

Cemented Total Knee Arthroplasty Shows Less Blood Loss but a Higher Rate of Aseptic Loosening Compared With Cementless Fixation: An Updated Meta-Analysis of Comparative Studies

BackgroundThe aim of this study was to update the current evidence on functional outcomes, complications, and reoperation rates between cemented and cementless total knee arthroplasty (TKA) by evaluating comparative studies published over the past 15 years.MethodsThe PubMed, MEDLINE, Scopus, and the Cochrane Central databases were used to search keywords and a total of 18 studies were included. Random and fixed effect models were used for the meta-analysis of pooled mean differences (MDs) and odds ratios (ORs).ResultsA total of 5,222 patients were identified with a mean age of 64.4 ± 9.4 and 63 ± 8.6 years for the cemented and cementless TKA groups, respectively. The mean follow-up was 107.9 ± 30 and 104.3 ± 10 months for the cemented and cementless TKA groups, respectively. Cemented TKA showed a significantly greater postoperative Knee Society Score (MD = ?0.95, 95% CI [?1.57, 0.33], P = .003) and range of motion (MD = ?1.09, 95% CI [?1.88, ?0.29], P = .0007), but no differences in other outcome scores were found. The incidence of periprosthetic joint infection, radiolucent lines, instability, and polyethylene wear was also comparable. Cemented TKA showed less perioperative blood loss (SMD = ?438.41, 95% CI [?541.69, ?35.14], P < .0001) but a higher rate of manipulation under anesthesia (OR = 3.39, 95% CI [1.64, 6.99], P = .001) and aseptic loosening (OR = 1.62, 95% CI [1.09, 2.41], P = .02) than cementless TKA. No differences were found in terms of the reoperation rate.ConclusionWhen cemented and cementless fixations are compared in primary TKA, comparable functional outcomes and reoperation rates can be achieved. Cemented TKA showed less blood loss but a higher rate of manipulation under anesthesia and aseptic loosening.     

A meta-analysis of the three-dimensional reconstruction visualization technology for hepatectomy

This meta-analysis was conducted to systematically evaluate the short-term efficacy and safety of the three-dimensional (3D) reconstruction visualization technology (3D-RVT) technique for hepatectomy. A systematic literature search was used to gather information on the 3D reconstruction visualization technology technique for hepatectomy from retrospective cohort studies and comparative studies. The retrieval period was up to March 2022. Publications and conference papers in English were manually searched and references in bibliographies traced. After evaluating the quality of selected studies, a meta-analysis was conducted using Review Manager 5.1 software. We included 12 studies comprising 2053 patients with liver disease. Our meta-results showed that 3D-RVT significantly shortened operation times [weighted mean differences (WMD) = ?29.36; 95% confidence interval (CI): ?55.20 to ?3.51; P = 0.03], reduced intraoperative bleeding [WMD = ?93.53; 95% CI: ?152.32 to ?34.73; P = 0.002], reduced blood transfusion volume [WMD = ?66.06; 95% CI: ?109.13 to ?22.99; P = 0.003], and shortened hospital stays [WMD = ?1.90; 95% CI: ?3.05 to ?0.74; P = 0.001]. Additionally, the technique reduced the use of hepatic inflow occlusion and avoided overall postoperative complications [odds ratio (OR) = 0.60; 95% CI: 0.46 to 0.79; P < 0.001]. 3D-RVT is safe and effective for liver surgery and provides safety assessments before anatomical hepatectomy.     

Meta-analysis of infrahepatic inferior vena cava clamping combined with the pringle maneuver during hepatectomy

This meta-analysis was conducted to evaluate the effectiveness and safety of infrahepatic inferior vena cava clamping combined with the Pringle maneuver during. hepatectomies. Clinical studies were retrieved from the PubMed, Embase, Cochrane Library, Medline and Web of Science databases. Study-specific effect sizes and their 95% confidence intervals (CIs) were combined to calculate the pooled value using a fixed-effects or random-effects model.Nine studies with 1008 patients in total were included. The infrahepatic inferior vena cava clamping combined with Pringle maneuver group experienced less total operative blood loss (mean difference [MD] = -327.11; 95% CI: -386.50–267.72; P < 0.00001), less blood loss during transection (MD = -270.19; 95% CI: -344.99–195.38; P < 0.00001), fewer blood transfusions (odds ratio [OR] = 0.36; 95% CI: 0.25–0.53;P < 0.00001) and fewer postoperative complications (OR = 0.70; 95% CI: 0.52–0.95; P = 0.02) than did the control group. Operative time (MD = 8.54; 95% CI: 4.68–12.40; P < 0.0001) was similar in both groups. liver transection time,hospital stay, postoperative liver function and renal function did not differ between groups.Applying infrahepatic inferior vena cava clamping combined with the Pringle maneuver can effectively reduce intraoperative bleeding, blood transfusion rates, and postoperative complications, while adding minimal time to the operation.     

Romosozumab versus Teriparatide for the Treatment of Postmenopausal Osteoporosis: A Systematic Review and Meta‐analysis through a Grade Analysis of Evidence

ObjectiveTo provide a systematic review about the efficacy and safety of romosozumab and teriparatide for the treatment of postmenopausal osteoporosis.MethodRandomized controlled trials (RCTs) were searched from electronic databases, including PubMed (1996 to June 2019), Embase (1980 to June 2019), Cochrane Library (CENTRAL, June 2019), Web of Science (1998 to June 2019), and others. The primary outcomes included the following: the percentage change in bone mineral density of lumbar spine and total hip from baseline at month 6 and month 12 in each group. The secondary outcomes included the following: the percentage change in bone mineral density of femoral neck from baseline at month 6 and month 12 in each group and the incidence of adverse events at month 12 in each group.ResultsFour studies containing 1304 patients met our selection criteria. The result of our analysis indicated that romosozumab showed better effects in improving BMD of lumbar spine (month 6: MD = 3.54, 95% CI [3.13, 3.94], P<0.001; month 12: MD = 4.93, 95% CI [4.21, 5.64], P<0.001), total hip (month 6: MD = 2.27, 95% CI [0.62, 3.91], P = 0.007; month 12: MD = 3.17, 95% CI [2.68, 3.65], P<0.001), and femoral neck (month 6: MD = 2.30, 95% CI [0.51, 4.08], P = 0.01; month 12: MD = 3.04, 95% CI [2.29, 3.78], P<0.001). Also, the injection‐site reaction was less (month 12: RR = 2.84, 95% CI [1.22, 6.59], P = 0.02), but there were no significant difference in the incidence of serious adverse events (month 12: RR = 0.78, 95% CI [0.46, 1.33], P = 0.37) and death (month 12: RR = 0.61, 95% CI [0.08, 4.62], P = 0.63).ConclusionBased on the available studies, our current results demonstrate that romosozumab was better than teriparatide both in terms of efficacy and side effects.     

Predictors of preoperative deep vein thrombosis in hip fractures: A systematic review and meta-analysis

BackgroundThe predictors of preoperative deep vein thrombosis (DVT) in patients with hip fractures remain unclear. Therefore, this study describes the results of a systematic review and meta-analysis of relevant peer-reviewed literature on this topic.MethodsWe searched PubMed, Google Scholar, Cochrane Library, Web of Science, and MEDLINE for articles published in English on the predictors of preoperative DVT in hip fractures. We calculated pooled odds ratios (OR) or mean differences (MD) for the DVT groups as compared with the non-DVT groups for each variable, including gender, age, body mass index, injury side, current smoking status, time from injury to admission, time from injury to surgery, fracture type, hypertension, arrhythmia, coronary artery disease, diabetes, stroke, kidney disease, liver disease, lung disease, malignancy, rheumatoid arthritis, D-dimer, fibrinogen, activated partial thromboplastin time, prothrombin time, thrombin time, hemoglobin, albumin, total cholesterol, and triglycerides.ResultsWe included 9 studies involving 3,123 Asian patients with hip fractures (DVT, n = 570; non-DVT, n = 2,553). Being female (OR = 1.27; 95% confidence interval [CI] 1.04–1.56; p = 0.02), being of advanced age (MD = 1.63; 95% CI 0.80–2.47; p = 0.0001), having a longer time from injury to admission (MD = 0.80; 95% CI 0.48–1.12; p < 0.00001), having a longer time from injury to surgery (MD = 2.20; 95% CI 1.53–2.88; p < 0.00001), and the presence of kidney disease (OR = 1.76; 95% CI 1.04–2.96; p = 0.03) were correlated with a high risk of DVT. However, we found no significant differences between the two groups in the other predictors.ConclusionsEvidence indicates that being female, being of advanced age, having a longer time from injury to admission, having a longer time from injury to surgery, and having kidney disease are significantly correlated with a high risk of preoperative DVT in Asian patients with hip fracture. Further investigations with patients of other ethnicities are required.     

Level III axillary lymph nodes involvement in node positive breast cancer received neoadjuvant chemotherapy

ObjectiveTo investigate the incidence, associated factors and prognosis of level III node involvement for breast cancer with positive axillary lymph nodes after neoadjuvant chemotherapy.MethodsA consecutive series of 521 node positive T_0–2 invasive breast cancer cases were included in this retrospective study. Axillary node metastases were proved by ultrasound guided needle biopsy (NB) if ultrasonographic abnormal node was detected or by sentinel node biopsy (SNB) if no abnormal node was detected. After 4 to 8 cycles of neoadjuvant chemotherapy (NCT）, axillary lymph nodes dissection included level III lymph nodes were completed for each case.ResultsThe pathologic complete response rate of axillary nodes was 31.1% (90/289) in NB positive subgroup. The incidence of residual positive level III lymph nodes were 9.0% (47/521). Multivariate analysis showed that node NB positivity (OR = 2.212, 95% CI: 1.022–4.787, P = 0.044), clinical tumor size >2 cm before NCT (OR = 2.672, 95% CI: 1.170–6.098, P = 0.020), and primary tumor non-response to neoadjuvant chemotherapy (OR = 1.718, 95% CI: 1.232–2.396, P = 0.001) were independent predictors of level III lymph nodes positivity. At median follow-up time of 30 months, the distant disease-free survival (DDFS) rate of level III node positive group was much lower than that of level III negative group (p = 0.011).ConclusionsAbout 9% of node positive T_0–2 breast cancer will have residual positive node in level III region after neoadjuvant chemotherapy. Node positivity proved by NB, large tumor size, and primary tumor non-response to neoadjuvant chemotherapy are independent predictors of level III lymph nodes positivity.     

Evaluating postoperative outcomes in patients with hostile neck anatomy undergoing transcarotid artery revascularization versus transfemoral carotid artery stenting

BackgroundCarotid endarterectomy is relatively contraindicated in patients with a hostile neck anatomy who were historically revascularized with transfemoral carotid artery stenting (TFCAS). As transcarotid artery revascularization (TCAR) has progressively replaced TFCAS, evidence pertaining to hostile neck anatomy and TCAR is necessary to establish its safety and feasibility in this subgroup of patients. Therefore, we analyzed the impact of a hostile neck anatomy on outcomes in patients undergoing TCAR and further compared them with those undergoing TFCAS to establish recommendations for standard of care.MethodsAll patients undergoing TCAR and TFCAS from November 2016 to June 2021 in the Vascular Quality Initiative database were included. Patients were characterized into two groups based on the neck anatomy. Hostile neck anatomy was defined as a history of neck radiation or prior neck surgery including prior carotid endarterectomy or radical neck dissection. Primary outcomes included technical failure, access site complications (hematoma, stenosis, infection, pseudoaneurysm and arteriovenous fistula), and stroke or death. Secondary outcomes included stroke, transient ischemic attack (TIA), myocardial infarction (MI), death, and a composite end point of stroke or TIA. Patients with nonatherosclerotic or multiple lesions were excluded from the analysis. Primary analysis was performed with all patients undergoing TCAR and outcomes between patients with hostile and nonhostile neck anatomy were compared. Further analysis included a comparison of patients with a hostile neck anatomy undergoing TCAR and TFCAS. Univariable and multivariable logistic regression was used to assess impact of hostile neck anatomy on postoperative outcomes. Results were adjusted for relevant potential confounders including age, gender, race, degree of stenosis, symptomatic status, comorbidities, preoperative medications, anesthesia type, and protamine use.ResultsAmong the 19,859 patients who underwent TCAR during the study period, 3636 (18.3%) had a hostile neck anatomy. On univariate analysis, both groups had comparable outcomes except for higher rates of stroke or death in patients with hostile neck anatomy. After adjusting for potential confounders, there were no differences in technical failure (adjusted odds ratio [aOR], 1.14; 95% confidence interval [CI], 0.59-2.21; P = .699), stroke (aOR, 0.86; 95% CI, 0.58-1.28; P = .464), death (aOR, 0.82; 95% CI, 0.39-1.71; P = .598), and MI (aOR, 1.18; 95% CI, 0.71-1.97; P = .518). However, patients with hostile neck were at a 30% increased risk of access site complications (aOR, 1.30; 95% CI, 1.0-1.6; P = .023). Further adjusted analysis comparing the outcomes in TFCAS and TCAR among patients with hostile neck anatomy showed an almost four-fold increase in risk of death (aOR, 3.77; 95% CI, 1.49-9.53; P = .005) and technical failure (aOR, 3.69; 95% CI, 1.82-7.47; P < .001) among patients undergoing treatment with TFCAS.ConclusionsPatients with a hostile neck anatomy undergoing TCAR experienced an increased risk of access site complications; however, the risk for technical failure and postoperative stroke/death, stroke, TIA, MI, or death was similar among both groups. TFCAS was associated with significant increase in the risk of death and technical failure compared with TCAR in this group of patients. These results confirm that TCAR should be the preferred minimally invasive revascularization procedure for patients with hostile neck anatomy.     

Relationship Between Mental Health Disorders and Readmissions Following Total Joint Arthroplasty: A Systematic Review and Meta-Analysis

BackgroundThere is limited evidence exploring the relationship between mental health disorders and the readmissions following total joint arthroplasty (TJA). Therefore, we conducted a meta-analysis to evaluate the relationship between mental health disorders and the risk of readmission following TJA.MethodsWe searched PubMed, Cochrane, and Google Scholar from their inception till April 19, 2022. Studies exploring the association of mental health disorders and readmission risk following TJA were selected. The outcomes were divided into 30-day readmission, 90-day readmission, and readmission after 90 days. We also performed subgroup analyses based on the type of arthroplasty: total hip arthroplasty (THA) and total knee arthroplasty (TKA). A total of 12 studies were selected, of which 11 were included in quantitative analysis. A total of 1,345,893 patients were evaluated, of which 73,953 patients suffered from mental health disorders.ResultsThe risk of 30-day readmission (odds ratio = 1.43, 95% CI 1.14-1.80, P = .002, I² = 87%) and 90-day readmission (OR = 1.35, 95% CI 1.22-1.49, P < .00001, I² = 89%) was significantly associated with mental health disorders. On subgroup analyses, 30-day readmission was significantly associated with THA (OR = 1.29, 95% CI 1.04-1.60, P = .02), but not with TKA (OR = 1.44, 95% CI 0.51-4.06, P = .50). Similarly, 90-day readmission was significantly associated with both THA (OR = 1.21, 95% CI 1.14-1.29, P < .00001) and TKA (OR = 1.33, 95% CI 1.17-1.51, P < .0001).ConclusionMental health disorders are significantly associated with increased 30-day and 90-day readmissions. Increasing awareness regarding mental health disorders and readmission in arthroplasty will help in efficient preoperative risk stratification and better postoperative management in these patients.     

Augmented Microfracture Technique Versus Microfracture in Talar Cartilage Restoration: A Systematic Review and Meta-Analysis

The aim of this meta-analysis was to compare the efficacy and safety between the microfracture (MFx) and augmented microfracture (MFx+) techniques for articular cartilage defects of the talus (OLTs). PubMed and EMBASE were searched from January 1950 to October 2020. Only randomized controlled trials, quasi-randomized controlled trials, and observational studies (retrospective and prospective) applying MFx and MFx+ techniques to treat talar cartilage defects were selected. Ten trials with 492 patients were included. There was significant difference in final American Orthopaedic Foot & Ankle Society score (AOFAS) (mean difference [MD] = 7.07; 95% confidence interval [CI], 3.70-10.44; p < .01), AOFAS change (MD = 7.97; 95% CI, 4.27-11.66; p < .01), visual analog scale (VAS) change score (MD = 0.44; 95% CI, 0.29-0.59; p < .01), Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score (MD = 12.51; 95% CI, 7.16-17.86; p < .01), complication (RR = 0.33; 95% CI, 0.16-0.69; p < .01), and revision (Relative risk = 0.34; 95% CI, 0.15-0.77; p < .05), between the MFx and MFx+ groups. No significant difference was observed for final VAS pain score (MD = -0.53; 95% CI, -1.2 to 1.05; p = .13) and Tegner scale (MD = 0.31; 95% CI, -1.05 to 1.66; p = .66) in either group. Our results suggest that augmented microfracture is superior to microfracture alone in the treatment of talar OLTs based on the AOFAS, MOCART, VAS score, complication rate, and revision ratio. Therefore, microfracture with augmentation should be considered as a treatment for OLTs of talus. However, more randomized trials are still required to determine the long-term superiority of MFx+.     

Clinical outcomes in patients with retear after arthroscopic rotator cuff repair: A meta-analysis

BackgroundRotator cuff retear is a major concern after arthroscopic rotator cuff repair (ARCR); however, the effects of retear remain unclear. Therefore, the purpose of this study was to assess the clinical outcomes of postoperative retear and intact tendons after ARCR.MethodsWe searched PubMed, Cochrane Library, Scopus, and PEDro databases for studies performed from January 2000 to June 2020. Clinical outcomes included the Constant score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles shoulder (UCLA) score, pain score, range of motion, and muscle strength. Meta-analysis using random-effects models was performed on the pooled results to determine significance.ResultsThe initial database search yielded 3141 records. After removal of duplicates, 26 of which met the inclusion criteria. Patients in the retear group had significantly lower Constant score [? 8.51 points (95% CI, ? 10.29 to ? 6.73); P < 0.001], ASES score [? 12.53 points (95% CI, ? 16.27 to ? 8.79); P < 0.001], UCLA score [? 3.77 points (95% CI, ? 4.72 to ? 2.82); P < 0.001], and significantly higher pain score [0.56 cm (95% CI, 0.10 to 1.01); P = 0.02] than the intact group. In addition, the retear group had significantly lower flexion [? 10.46° (95% CI, ? 19.86 to ? 1.07); P = 0.03], abduction [? 14.84° (95% CI, ? 28.55 to ? 1.14); P = 0.03], and external rotation [? 7.22° (95% CI, ? 13.71 to ? 0.74); P = 0.03] range of motion, and flexion [? 1.65 kg·f (95% CI, ? 2.29 to ? 1.01); P < 0.001], abduction [? 1.87 kg·f (95% CI, ? 3.02 to ? 0.72); P = 0.001], and external rotation [? 1.66 kg·f (95% CI, ? 3.25 to ? 0.07); P = 0.04] muscle strength.ConclusionOur results suggest that retear after ARCR leads to poor clinical outcomes after surgery.     

Does Regional Anesthesia Reduce Complications Following Total Hip and Knee Replacement Compared With General Anesthesia? An Analysis From the National Joint Registry for England,Wales, Northern Ireland and the Isle of Man

BackgroundRegional anesthesia is increasingly used in enhanced recovery programs following total hip replacement (THR) and total knee replacement (TKR). However, debate remains about its potential benefit over general anesthesia given that complications following surgery are rare. We assessed the risk of complications in THR and TKR patients receiving regional anesthesia compared with general anesthesia using the world’s largest joint replacement registry.MethodsWe studied the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man linked to English hospital inpatient episodes for 779,491 patients undergoing THR and TKR. Patients received either regional anesthesia (n = 544,620, 70%) or general anesthesia (n = 234,871, 30%). Outcomes assessed at 90 days included length of stay, readmissions, and complications. Regression models were adjusted for patient and surgical factors to determine the effect of anesthesia on outcomes.ResultsLength of stay was reduced with regional anesthesia compared with general anesthesia (THR = −0.49 days, 95% confidence interval [CI] = −0.51 to −0.47 days, P < .001; TKR = −0.47 days, CI = −0.49 to −0.45 days, P < .001). Regional anesthesia also had a reduced risk of readmission (THR odds ratio [OR] = 0.93, CI = 0.90-0.96; TKA OR = 0.91, CI = 0.89-0.93), any complication (THR OR = 0.88, CI = 0.85-0.91; TKA OR = 0.90, CI = 0.87-0.93), urinary tract infection (THR OR = 0.85, CI = 0.77-0.94; TKR OR = 0.87, CI = 0.79-0.96), and surgical site infection (THR OR = 0.87, CI = 0.80-0.95; TKR OR = 0.84, CI = 0.78-0.89). Anesthesia type did not affect the risk of revision surgery or mortality.ConclusionRegional anesthesia was associated with reduced length of stay, readmissions, and complications following THR and TKR when compared with general anesthesia. We recommend regional anesthesia should be considered the reference standard for patients undergoing THR and TKR.     

Does diabetes mellitus change the carpal tunnel release outcomes? Evidence from a systematic review and meta-analysis

Study DesignA systematic review and meta-analysis.IntroductionCarpal tunnel syndrome (CTS) is one of the most common upper extremity conditions which mostly affect women. Management of patients suffering from both CTS and diabetes mellitus (DM) is challenging, and it was suggested that DM might affect the diagnosis as well as the outcome of surgical treatment.Purpose of the StudyThis meta-analysis was aimed to compare the response with CTS surgical treatment in diabetic and nondiabetic patients.MethodsElectronic databases were searched to identify eligible studies comparing the symptomatic, functional, and neurophysiological outcomes between diabetic and nondiabetic patients with CTS. Pooled MDs with 95% CIs were applied to assess the level of outcome improvements.ResultsTen articles with 2869 subjects were included. The sensory conduction velocities in the wrist-palm and wrist–middle finger segments showed a significantly better improvement in nondiabetic compared with diabetic patients (MD = −4.31, 95% CI = −5.89 to −2.74, P < .001 and MD = −2.74, 95% CI = −5.32 to −0.16, P = .037, respectively). However, no significant differences were found for the improvement of symptoms severity and functional status based on the Boston Carpal Tunnel Questionnaire and Quick Disabilities of the Arm, Shoulder, and Hand questionnaire as well as motor conduction velocities and distal motor latencies.ConclusionMetaresults revealed no significant difference in improvements of all various outcomes except sensory conduction velocities after CTS surgery between diabetic and nondiabetic patients. A better diabetic neuropathy care is recommended to achieve better sensory recovery after CTS surgery in diabetic patients.     

Influencing factors for the recurrence of diabetic foot ulcers: A meta-analysis

This study aims to systematically review and identify the related influencing factors for the recurrence of diabetic foot ulcers (DFUs)in diabetic patients. We searched PUBMED, EMBASE, Web of Science, Cochrane Library, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Wan Fang and VIP databases to identify eligible studies published before March 31, 2022 to collect case–control studies or cohort studies on the related influencing factors for the recurrence of DFUs. Two reviewers independently screened the literature, and extracted data. Also, they assessed the risk of bias of the included studies using the Newcastle-Ottawa Scale. A meta-analysis was performed using RevMan5.4.1 software. 20 studies were included; 4238 patients were enrolled, in which 1567 were in the DFU recurrence group and 2671 were in the non-recurrent DFU group. Risk factors for the recurrence of DFUs included diabetic peripheral neuropathy (odds ratio [OR] = 4.05, 95% CI, 2.50-6.58, P < 0.00001), peripheral vascular disease (OR = 3.94, 95% CI, 2.65-5.84, P < 0.00001), poor blood glucose control (OR = 3.27, 95% confidence interval [CI], 2.79-3.84, P < 0.00001), plantar ulcer (OR = 3.66, 95% CI, 2.06-6.50, P < 0.00001), osteomyelitis (OR = 7.17, 95% CI, 2.29-22.47, P = 0.0007), smoking (OR = 1.98, 95% CI, 1.65-2.38, P < 0.00001), history of amputation (OR = 11.96, 95%CI, 4.60-31.14, P < 00001), multidrug-resistant bacterial infection (OR = 3.61, 95%CI, 3.13-4.17, P < 0.00001), callus (OR = 5.70, 95%CI, 1.36-23.89, P = 0.02), previous diabetic foot ulcer (OR = 4.10, 95% CI, 2.58-6.50, P < 0.00001), duration of previous diabetic foot ulcer >60d (OR = 1.02, 95% CI, 1.00-1.03, P = 0.004), history of vascular intervention (OR = 3.20, 95% CI, 2.13-4.81, P < 0.00001) and Wagner grade III/IV (OR = 4.40, 95% CI, 2.21-8.78, P < 0.0001). However, no significant differences were found in age, duration of diabetes, body mass index, total cholesterol or foot deformity. Recurrence of diabetic foot ulcers is affected by a variety of factors. Thus, we should focus on high-risk groups and take targeted interventions as soon as possible to reduce the recurrence rate of DFUs, because of the limited quality and quantity of the included studies, more rigorous studies with adequate sample sizes are needed to verify the conclusion.     

Clinical and Patient-Reported Outcomes of Medial Stabilized Versus Non–Medial Stabilized Prostheses in Total Knee Arthroplasty: A Systematic Review and Meta-Analysis

BackgroundThe aim of this systematic review and meta-analysis was to compare the clinical and patient-reported outcome measures (PROMs) of medial stabilized total knee arthroplasty (TKA) with non–medial stabilized TKAs.MethodsA systematic search of multiple databases was conducted in October 2019. A meta-analysis was conducted for the Knee Society Score (KSS), Knee Society Functional Score (KFS), range of motion (ROM), Oxford Knee Score (OKS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Forgotten Joint Score (FJS).ResultsA total of 857 articles yielded 21 studies eligible for inclusion with 13 studies used for quantitative analysis. The meta-analysis revealed that the medial stabilized group had a mean FJS that was 13.8 points higher than that of the non–medial stabilized TKA (mean difference [MD]: 13.83, P ≤ .0001, 95% confidence interval [CI]: 8.90-18.76, I² = 0%) which was less than the minimal clinically important difference of 14. The medial stabilized group also demonstrated a statistically significant difference in the postoperative ROM (MD = 2.52, P = .05, 95% CI: ?0.03 to 5.07, I² = 85%) and OKS when compared with the non–medial stabilized group (MD = 1.25, P = .02, 95% CI: 0.17-2.33, I² = 27%), but these were not clinically significant. There was no statistically or clinically significant difference in the KSS, KFS, and WOMAC scores.ConclusionMedial stabilized knee prostheses demonstrated no clinically significant differences for the ROM, OKS, WOMAC, KSS, and KFS. The FJS demonstrated the greatest MD and warrants further investigation. Future research is required using patient-reported outcome measures with a lower ceiling effect such as the FJS.     

Lymph node metastasis between the sternocleidomastoid and sternohyoid muscle in papillary thyroid carcinoma patients: A prospective study at multiple centers

BackgroundThe lymph nodes between the sternocleidomastoid and sternohyoid muscle (LNSS) are not explicitly mentioned in the 2015 American Thyroid Association and 2008 American Head and Neck Society (AHNS) guidelines, but they are easily overlooked in papillary thyroid carcinoma (PTC). We prospectively evaluated the clinical significance of the LNSS in papillary thyroid carcinoma (PTC) patients.MethodIn five medical centers, two hundred and thirty-four PTC patients with lateral neck metastasis who underwent 264 neck dissection were enrolled in this study. LNSS was resected and used as a specimen to investigate the relationship of LNSS with several clinicopathological parameters.ResultOf the 264 lateral neck dissections, the average lymph node metastasis rate of LNSS was 23.48%, significantly second only to that in level III (p<0.05). Univariate and multivariate analyses showed that a patient age over 45 years (OR 2.155, 95% CI 1.191 to 3.898, p = 0.011), with a tumor located in the inferior lobe of the thyroid (OR 1.517, 95% CI 1.113 to 2.068, p = 0.008), and LN metastasis at levels IIb (OR 2.298, 95% CI 1.121 to 4.712, p = 0.020) and level III (OR 2.408, 95% CI 1.222 to 4.745, p = 0.011) were independent risk factors for LNSS lymphatic metastasis.ConclusionThe LNSS has a high metastatic rate and is easily overlooked. Additional attention should be paid to LNSS, especially in patients over 45 years old and with PTC located in the thyroid’s inferior lobe.     

Are Patients Being Appropriately Selected for Same-Day Discharge Total Knee Arthroplasty?

BackgroundDecreased cost associated with same-day discharge (SDD) total knee arthroplasty (TKA) has led to an increased interest in this topic. The purpose of this study is to investigate whether there is a population of TKA patients in which SDD has similar rates of 30-day complications compared to patients discharged on postoperative day 1 or 2.MethodsUsing the American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2018, 6,327 TKA patients who had a SDD (length of stay [LOS] = 0) were matched to TKA patients who had an LOS of 1 or 2 days. All SDD patients were successfully matched 1:1 using the morbidity probability variable (a composite variable of demographics, comorbidities, and laboratory values). Patients were divided into quartiles based on their morbidity probability. Bivariate logistic regressions were then used to compare any complication and major complication rates in the SDD quartiles to the corresponding quartiles with an LOS of 1 or 2 days.ResultsWhen comparing the 1st quartiles (healthiest), there was no difference between the cohorts in any complication (odds ratio [OR] = 0.960, 95% CI 0.552-1.670, P = .866) and major complications (OR = 0.999, 95% CI = 0.448-2.231, P = .999). The same was observed in quartile 2 (any complications: OR = 1.161, 95% CI = 0.720-1.874, P = .540). Comparing the third quartiles, there was an increase in all complications with SDD (OR = 1.784, 95% CI = 1.125-2.829, P = .014), but no difference in major complications (OR = 1.635, 95% CI = 0.874-3.061, P = .124). Comparing the fourth quartiles (least healthy), there was an increase in all complications (OR = 1.384, 95% CI = 1.013-1.892, P = .042) and major complications (OR = 1.711, 95% CI = 1.048-2.793, P = .032) with SDD.ConclusionThe unhealthiest 50% of patients in this study who underwent SDD TKA were at an increased risk of having any complication, calling into question the current state of patient selection for SDD TKA.Level of EvidenceIII.     

Effect of prophylactic central neck dissection following total thyroidectomy on surgical site wound infection,hematoma, and haemorrhage in subjects with clinically node-negative papillary thyroid carcinoma: A meta-analysis

We performed a meta-analysis to evaluate the effect of prophylactic central neck dissection following total thyroidectomy on surgical site wound infection, hematoma, and haemorrhage in subjects with clinically node-negative papillary thyroid carcinoma. A systematic literature search up to April 2022 was performed and 3517 subjects with clinically node-negative papillary thyroid carcinoma at the baseline of the studies; 1503 of them were treated with prophylactic central neck dissection following total thyroidectomy, and 2014 were using total thyroidectomy. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of prophylactic central neck dissection following total thyroidectomy on surgical site wound infection, hematoma, and haemorrhage in subjects with clinically node-negative papillary thyroid carcinoma using the dichotomous method with a random or fixed-effect model. The prophylactic central neck dissection following total thyroidectomy subjects had a significantly lower surgical site wound infection (OR, 0.40; 95% CI, 0.20–0.78, P = .007) in subjects with clinically node-negative papillary thyroid carcinoma compared with total thyroidectomy. However, prophylactic central neck dissection following total thyroidectomy did not show any significant difference in hematoma (OR, 0.08; 95% CI, 0.43–2.71, P = .87), and haemorrhage (OR, 0.72; 95% CI, 0.26–1.97, P = .52) compared with total thyroidectomy in subjects with clinically node-negative papillary thyroid carcinoma. The prophylactic central neck dissection following total thyroidectomy subjects had a significantly higher surgical site wound infection, and no significant difference in hematoma, and haemorrhage compared with total thyroidectomy in subjects with clinically node-negative papillary thyroid carcinoma. The analysis of outcomes should be with caution because of the low number of studies in certain comparisons.     

Hospital Frailty Risk Score Predicts Adverse Events in Primary Total Hip and Knee Arthroplasty

BackgroundThe Hospital Frailty Risk Score (HFRS) is a validated geriatric comorbidity measure derived from routinely collected administrative data. The purpose of this study is to evaluate the utility of the HFRS as a predictor for postoperative adverse events after primary total hip (THA) and knee (TKA) arthroplasty.MethodsIn a retrospective analysis of 8250 patients who had undergone THA or TKA between 2011 and 2019, the HFRS was calculated for each patient. Reoperation rates, readmission rates, complication rates, and transfusion rates were compared between patients with low and intermediate or high frailty risk. Multivariate logistic regression models were used to assess the relationship between the HFRS and postoperative adverse events.ResultsPatients with intermediate or high frailty risk showed a higher rate of reoperation (10.6% vs 4.1%, P < .001), readmission (9.6% vs 4.3%, P < .001), surgical complications (9.1% vs 1.8%, P < .001), internal complications (7.3% vs 1.1%, P < .001), other complications (24.4% vs 2.0%, P < .001), Clavien-Dindo grade IV complications (4.1% vs 1.5%, P < .001), and transfusion (10.4% vs 1.3%, P < .001). Multivariate logistic regression analyses revealed a high HFRS as independent risk factor for reoperation (odds ratio [OR] = 2.1; 95% confidence interval [CI], 1.46-3.09; P < .001), readmission (OR = 1.78; 95% CI, 1.21-2.61; P = .003), internal complications (OR = 3.72; 95% CI, 2.28-6.08; P < .001), surgical complications (OR = 3.74; 95% CI, 2.41-5.82; P < .001), and other complications (OR = 9.00; 95% CI, 6.58-12.32; P < .001).ConclusionThe HFRS predicts adverse events after THA and TKA. As it derives from routinely collected data, the HFRS enables hospitals to identify at-risk patients without extra effort or expense.Level of EvidenceLevel III–retrospective cohort study.
