RESUMO

: Since the beginning of 2020, the world has been confronted by the Covid-19 pandemic. The lock-down aims to limit the circulation of the virus and thus avoid overwhelming healthcare systems. Healthcare workers have had to adapt by postponing consultation and surgical activities. Otolaryngologists are particularly exposed to infection from the upper airway where the virus is highly concentrated. Literature has previously reported other human coronaviruses in the middle ear and mastoid, suggesting a risk of infection to staff during ear surgery where aerosolizing procedures are usually used. The aim of this article is to propose a strategy for planning consultations and surgeries for ear and lateral skull base diseases, in the context of the current active evolution of the pandemic and of the future gradual recovery to normal practice.

RESUMO

AIMS: Preoperative nasal Staphylococcus aureus screening and eradication reduces surgical site infections (SSIs) but its impact on reducing early prosthetic joint infection (PJI) remains controversial. This study aims to assess the effect of preoperative nasal S. aureus screening and eradication on the incidence of early PJI in general and S. aureus-induced early PJI. METHODS: All primary total hip arthroplasties (THA) and total knee arthroplasties (TKA) performed from January 2006 to April 2018 were retrospectively reviewed for the incidence of early PJI. Demographic parameters, risk factors for PJI (American Society of Anaesthesiologists classification, body mass index, smoking status, and diabetes mellitus) and implant types were collected. A preoperative screening and eradication protocol for nasal colonization of S. aureus was introduced in October 2010. The incidence of early PJI was compared before and after the implementation of the protocol. Missing data were imputed via multiple imputation by chained equations. Inverse probability weighting was used to account for differences between patients in both groups. Weighted univariate logistic regression was used to evaluate the incidence of early PJI for both groups. RESULTS: In total, 10,486 THAs and TKAs were performed in the research period. After exclusion, a cohort of 5,499 screened cases and 3,563 non-screened cases were available for analysis. Overall, no significant reduction in early PJI was found in the screened group (odds ratio (OR) 0.78, 95% confidence interval (CI) 0.55 to 1.11; p = 0.173). However, the incidence of S. aureus-induced PJI was significantly reduced (OR 0.58, 95% CI 0.36 to 0.92; p = 0.027) in the screened group. CONCLUSION: A preoperative nasal S. aureus screening and eradication protocol did not significantly reduce the overall incidence of early PJI after THA or TKA. However, a decreased incidence of S. aureus-induced early PJI was established. These findings can help to establish better consensus around the value of these screening protocols.

RESUMO

Massive blood transfusion (MBT) is a relatively common complication of cardiac surgery, which is independently associated with severe postoperative adverse events. However, the value of using rapid thrombotomography (r-TEG) to predict MBT in perioperative period of cardiac surgery has not been explored. This study aimed to identify the effect of r-TEG in predicting MBT for patients undergoing coronary artery bypass grafting (CABG).This retrospective study included consecutive patients first time undergoing CABG at the Zhongnan Hospital of Wuhan University between March 2015 and November 2017. All the patients had done r-TEG tests before surgery. The MBT was defined as receiving at least 4 units of red blood cells intra-operatively and 5 units postoperatively (1 unit red blood cells from 200 mL whole blood).Lower preoperative hemoglobin level (P = .001) and longer cardiopulmonary bypass time (P = .001) were the independent risk factors for MBT during surgery, and no components of the r-TEG predicted MBT during surgery. Meanwhile, longer activated clotting time (P < .001), less autologous blood transfusion (P = .001), and older age (P = .008) were the independent risk factors for MBT within 24 hours of surgery.Preoperative r-TEG activated clotting time can predict the increase of postoperative MBT in patients undergoing CABG. We recommend the careful monitoring of coagulation system with r-TEG, which allows rapid diagnosis of coagulation abnormalities even before the start of surgery.

RESUMO

BACKGROUND: Adequate bowel preparation is essential for the detection of pathological lesions during colonoscopy. However, it has been found to be inadequate in approximately 20% to 30% of colonoscopy examinations. Educational interventions focused on health staff, such as physicians and nurses, may improve the patients' understanding of the bowel preparation instructions, and consequently, increase the quality of bowel preparation. OBJECTIVES: To investigate whether enhanced education of ward nurses could improve the bowel preparation quality in inpatients undergoing colonoscopy. DESIGN: This was a single-center randomized controlled study. METHODS: A total of 190 consecutive inpatients scheduled to undergo colonoscopy from March 2019 to March 2020 were randomized to the educated (nurses with enhanced education) or control group (nurses without enhanced education). We assessed the bowel preparation quality using the Boston bowel preparation scale. RESULTS: There were 89 patients in the educated group and 101 patients in the control group. The proportion of colonoscopies with adequate bowel preparation was 83.1% in the educated group and 69.3% in the control group. Patients' compliance with bowel preparation in the educated group was superior to that in the control group. Furthermore, significantly better sleep quality was found in the educated group. The multivariate logistic regression analysis identified the ward nurses-focused enhanced educational intervention as a risk factor for bowel preparation quality. CONCLUSIONS: The ward nurses-focused educational intervention improved the bowel preparation quality and reduced the adverse event rates in inpatients undergoing colonoscopy. TRIAL REGISTRATION: This study was registered in the Chinese Clinical Trial Registry under number ChiCTR2000030366.

RESUMO

BACKGROUND: Current demographics lead increasing older cancer patients to undergo complex medico-surgical procedures, with substantial risk of decompensations and deconditioning. The Prehabilitation & Rehabilitation in Oncology: Adaptation to Disease and Accompaniment of Patients' Trajectories (PROADAPT) project is currently being developed with the aim of improving care, through standardized care pathways guided by existing evidence and implementation programs. A working group will specifically focus on improvement of physical performances before such procedures. These interventions may have been developed in different contexts: before surgery in large, before carcinologic surgery or complex medical interventions (chemotherapy, radiotherapy), or in primary care for elderly patients to prevent sarcopenia and frailty. Post-surgical interventions are out of the scope of this review. The objective of this review is to summarize the level of evidence to support physical reconditioning interventions and identify areas where further work is required. METHODS: This umbrella review will include moderate to high quality systematic reviews, meta-analysis, and pre-existing umbrella or meta-reviews. Two reviewers will independently search the following databases: PubMed/MedLine, Cochrane Library, Embase, and CINAHL. Research strategy will use diverse keywords used to refer to the concepts of "prehabilitation," "preoperative exercise," or "preoperative rehabilitation," with prespecified inclusion and exclusion criteria and only systematic reviews selection. The distinct types of interventions presented using PRISMA guidelines and a narrative reporting of results. A focus will be made on outcomes such as physical performances, quality of life, autonomy in everyday activities, or number of hospital bed days. ETHICS AND DISSEMINATION: Ethical approval is not required for such an umbrella review. Our review will be submitted for publication in a peer-reviewed international journal using open access option if available. It will be complementary to reviews focused on hospital discharge of older people. PROSPERO REGISTRATION NUMBER: CRD42020100110.

RESUMO

Introducción: La planificación preoperatoria favorece la realización de un acto quirúrgico sin complicaciones. Actualmente existe escasa información a nivel nacional sobre la eficacia de la planificación pre-operatoria digital por lo que el objetivo del presente estudio es el analizar los resultados de la implementación de esta estrategia en una población de pacientes con indicación de artroplastia total de cadera. Materiales y métodos: Estudio observacional, prospectivo, analítico. Se realizó un muestreo no probabilístico de casos consecutivos atendidos en la Cátedra de Ortopedia y Traumatología de la Facultad de Ciencias Médicas (U.N.A). Fueron captados pacientes >18 años con indicación de ATC, entre diciembre 2018 ­ octubre 2019, previo consentimiento informado. Se relevaron datos cuya caracterización fue posible mediante un instrumento establecido previamente, ingresado en base Excel. Se utilizó el software TraumaCad® versión 2.5 de Brainlab y marcadores radiológicos King Mark®. Fueron comparados ambos tipos de planificación ejecutando análisis estadísticos con el software R.v3.4.2., siendo un valor p ˂0.05, considerado estadísticamente significativa. Resultados: 57 pacientes fueron evaluados con el método digital y los resultados fueron comparados con los de 42 pacientes en los que se utilizó una planificación manual. La relación masculino-femenino fue 1/1, siendo los del grupo de 50 a 60 años, los más afectados. La coxartrosis primaria y la necrosis ósea aséptica fueron los diagnósticos más frecuentes. El tiempo quirúrgico, la correlación entre planificación y resultados para componentes acetabular, femoral, presentaron mejores resultados en el grupo de pacientes con planificación digital. Conclusión: La planificación digital comparada con la manual presentó mayor eficacia.


Introduction: Preoperative planning allows a surgical act without complications. It can be manual or digital. Its usefulness in total hip arthroplasty (ATC) is important, being digital seemingly more beneficial since it reduces surgical time and complications. The present study analyzed the effectiveness of the digital modality. Materials and methods: Observational, prospective, analytical study. Non-probabilistic sampling of consecutive cases attended in Department of Orthopedics and Traumatology of the Medicine Scholl (Universidad Nacional de Asunción). Patients> 18 years of age were indicated with ATC indication, between december 2018 to october 2019, with prior informed consent. Data whose characterization was made possible by means of a previously established instrument, entered in Excel basis, were released. Each patient had both types of planning: manual and digital. For TraumaCad® version 2.5 Brainlab software and King Mark® radiological markers were used for the digital. Both types of planning were compared by executing statistical analyzes with the software R.v3.4.2., being a value p <0.05, considered statistically significant. Results: 57 patients were evaluated with the digital method and 42 with the manual. The male-female ratio was 1/1, with those in the 50-60 age group being the most affected. The most frequent reason for consultation was hip pain, with primary coxarthrosis and aseptic bone necrosis being their cause. The consultation time 1 and surgery was 12.5 days. The surgical time, the correlation between planning and results for acetabular, femoral components, were more effective with digital planning. Conclusion: Digital planning compared to the manual is more effective.

RESUMO

The aim of this study was to analyze kinetic and morphologic features using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) with computer-aided diagnosis (CAD) to predict occult invasive components in cases of biopsy-proven ductal carcinoma in situ (DCIS).We enrolled 138 patients with 141 breasts who underwent preoperative breast MRI and were diagnosed with DCIS via ultrasonography (US)-guided core needle biopsy performed at our institution during January 2009 to December 2012. Their clinical, mammographic, ultrasonographic, MRI, and final histologic findings were retrospectively reviewed. Their mammographic, ultrasonographic, and MRI findings were analyzed according to the American College of Radiology Breast Imaging Reporting and Data System. CAD findings of detectability, initial (fast, medium, and slow) and delay (persistent, plateau, and washout) phase enhancement kinetic descriptor, peak enhancement percentage, and lesion size were evaluated. Continuous and categorical variables were analyzed using independent t test and χ or Fisher exact test, respectively. Independent factors for predicting the presence of invasive component were evaluated by multivariate logistic regression analysis.Final histologic findings revealed that 55 breasts (39%) had DCIS with an invasive component. MRI-detected, CAD-detected, or pathologic lesion size (P = .002, P = .001, P < .001, respectively), delay washout kinetics and detectability on CAD (P < .001 and P = .004, respectively), presence of symptoms (P = .01), presence of comedonecrosis (P < .001), nuclear grade (P = .001), abnormality on mammography (P = .02), or US (P = .03) were significantly different between pure DCIS and the DCIS with an invasive component group on univariate analysis. Of those findings, multivariate analysis revealed that delay washout on CAD (odds ratio [OR], 4.36; 95% confidence interval [CI], 1.96-9.69; P = .0003) and pathologic size (OR, 1.29; 95% CI 1.05-1.57; P = .014) were independent predictive factors for the presence of an invasive component.Delay washout kinetic features measured by CAD and pathologic tumor size are potentially useful for predicting occult invasion in cases of biopsy-proven DCIS.Breast MRI including a CAD system would be helpful for predicting invasive components in cases of biopsy-proven DCIS and for selecting patients for sentinel lymph node biopsy.

RESUMO

RATIONALE: Although rare, pancreatic neoplasms can occur during pregnancy, both in benign and malignant forms. Mucinous cystic neoplasms (MCNs) of the pancreas, a type of these neoplasms, are precursor lesions to invasive pancreatic cancer. The presence of the ovarian-type stroma is a defining feature. PATIENT CONCERNS: The first case was a 38-year-old woman in her 18th week of pregnancy with abdominal pain that worsens a few weeks later. The second case was a 30-year-old woman in her 17th week of pregnancy with abdominal pain in the left hypochondrium. DIAGNOSIS: The patients were under clinical examination and laboratory test including carbohydrate antigen 19-9 (CA 19-9) and carcinoembryonic antigen (CEA). Both patients had magnetic resonance imaging (MRI). The diagnosis of a MCNs of the pancreas was done preoperatively in the 2 cases. INTERVENTIONS: Both patients underwent distal pancreatectomy during pregnancy. One of them was an emergency laparotomy because of a ruptured MCN. OUTCOMES: Both patients were completely recovered from distal pancreatectomy and continued to full term, delivering a healthy baby by Caesarean section. After 6 years of follow-up, the first patient underwent a total gastrectomy, because of a gastric cancer with carcinomatosis. Currently the 2 patients are still alive after 8 years and 5 years of follow-up, respectively. LESSONS: Surgical resection of MCNs during pregnancy should be considered during the second trimester given common distal pancreas location, rapid growth, risk of spontaneous rupture, and malignant potential.

RESUMO

BACKGROUND: Labiaplasty has grown in popularity, but it remains controversial. Few studies have quantified the change in specific symptomatology from before to after labiaplasty to establish its effectiveness in improving quality of life. METHODS: In a prospective study, 62 patients undergoing labiaplasty completed written surveys privately in an examination room preoperatively and postoperatively about the presence of 11 physical and appearance-related symptoms. RESULTS: Mean patient age was 33.5 years (range, 17 to 61 years). Two patients were of minority age. All patients presented with at least one symptom, averaging 6.5 (range, one to 11). Most (82.2 percent) had a trim labiaplasty, and the rest (17.7 percent) had a wedge. After labiaplasty, 93.5 percent of patients were symptom-free, with the average dropping to 0.23 of 11 symptoms. Symptom-prevalence changes from preoperatively to postoperatively included self-consciousness, dropping from 93 percent to 6.5 percent; tugging (from 66.1 percent to 0 percent); feeling less attractive (from 66.1 percent to 0 percent); negative impact on self-esteem (from 64.5 percent to 1.6 percent); negative impact on intimacy (from 62.5 percent to 0 percent); twisting (from 58.1 percent to 3.2 percent); being uncomfortable (from 56.5 percent to 4.8 percent); clothing restriction (from 54.8 percent to 3.2 percent); visible outline (from 46.8 percent to 1.6 percent); pain (from 43.5 percent to 1.6 percent); and exposure in swimsuits (from 38.7 percent to 1.6 percent). No major complications occurred. Two patients felt their labia were still too long and revision was offered. Average follow-up was 13.3 months (range, 6 to 24 months). CONCLUSIONS: Patients with elongated labia have a high incidence of functional and appearance-related symptoms. Labiaplasty is a safe procedure that yields significant improvement in quality of life. CLINICAL QUESTIONS/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

BACKGROUND: Acute type A aortic dissection (ATAAD) is a life-threatening disease that requires emergent surgical intervention. This retrospective study aimed to clarify the individual characteristics, short-term and mid-term outcomes, and prognostic factors of patients who underwent surgical repair of ATAAD with preoperative cardiopulmonary resuscitation (CPR). METHODS: Between January 2007 and January 2020, 656 consecutive patients underwent ATAAD repair at our institution; 22 (3.4%) of these patients underwent CPR prior to surgery. Patients who underwent preoperative CPR were classified as the survivor group (n = 9) and non-survivor group (n = 13), according to whether they survived to hospital discharge. Clinical features, surgical information, and postoperative complications were analyzed and compared. Three-year cumulative survival rates and cerebral performance categories (CPC) scores are presented. RESULTS: In patients undergoing CPR prior to ATAAD surgery, the in-hospital mortality rate was 59.1%. A total of 72.7% of patients underwent concomitant surgical resuscitation procedures during CPR such as emergent subxiphoid pericardiotomy and/or emergent cardiopulmonary bypass. The survivor group had a higher rate of return of spontaneous heartbeat (ROSB) compared to the non-survivor group (100% versus 53.8%; P = 0.017). The 3-year cumulative survival rates were 35.1% (95% confidence interval [CI], 27.6%-42.6%) and 85.7% (95% CI, 81.9%-88.8%) for overall patients and for survivors, respectively. As for the neurological outcome, 77.8% (7/9) of patients had full cerebral performance (CPC-1) at the 3-month follow-up examination after discharge. CONCLUSIONS: Patients with ATAAD undergoing preoperative CPR, especially those without ROSB after CPR, are at high risk for in-hospital mortality. However, the short-term and mid-term outcomes, including the cerebral performance after discharge and 3-year survival rate, are promising for patients who survived to discharge.

RESUMO

PURPOSE: To test a new method to calculate the Intraocular Lens (IOL) power, that combines R Factor and ALxK methods, that we called Advance Lens Measurement Approach (ALMA). DESIGN: Retrospective, Comparative, Observational study. SETTING: Department of Medicine and Surgery, University of Salerno, Italy. METHODS: Ninety one eyes of 91 patients previously treated with Photorefractive Keratectomy (PRK) or Laser-Assisted in Situ Keratomileusis (LASIK) that underwent phacoemulsification and IOL implantation in the capsular bag were analyzed. For 68 eyes it was possible to zero out the Mean Errors (ME) for each formula and for selected IOL models, in order to eliminate the bias of the lens factor (A-Costant). Main outcome, measured in this study, was the median absolute error (MedAE) of the refraction prediction. RESULTS: In the sample with ME zeroed (68 eyes) both R Factor and ALxK methods resulted in MedAE of 0.67 D. For R Factor 33 eyes (48.53%) reported a refractive error <0.5D, and 53 eyes (77.94%) reported a refractive error <1D, For ALxK method, 32 eyes (47.06%) reported a refractive error <0.5 D, and 53 eyes (77.94%) reported a refractive error <1 D. ALMA method, reported a MedAE of 0.55 D, and an higher number of patients with a refractive error <0.5 D (35 eyes, 51.47%), and with a refractive error <1 D (54 eyes, 79.41%). CONCLUSIONS: Based on the results obtained from this study, ALMA method can improve R Factor and ALxK methods. This improvement is confirmed both by zeroing the mean error and without zeroing it.

RESUMO

AIMS: There is evidence that prior lumbar fusion increases the risk of dislocation and revision after total hip arthroplasty (THA). The relationship between prior lumbar fusion and the effect of femoral head diameter on THA dislocation has not been investigated. We examined the relationship between prior lumbar fusion or discectomy and the risk of dislocation or revision after THA. We also examined the effect of femoral head component diameter on the risk of dislocation or revision. METHODS: Data used in this study were compiled from several Finnish national health registers, including the Finnish Arthroplasty Register (FAR) which was the primary source for prosthesis-related data. Other registers used in this study included the Finnish Health Care Register (HILMO), the Social Insurance Institutions (SII) registers, and Statistics Finland. The study was conducted as a prospective retrospective cohort study. Cox proportional hazards regression and Kaplan-Meier survival analysis were used for analysis. RESULTS: Prior lumbar fusion surgery was associated with increased risk of prosthetic dislocation (hazard ratio (HR) = 2.393, p < 0.001) and revision (HR = 1.528, p < 0.001). Head components larger than 28 mm were associated with lower dislocation rates compared to the 28 mm head (32 mm: HR = 0.712, p < 0.001; 36 mm: HR = 0.700, p < 0.001; 38 mm: HR = 0.808, p < 0.140; and 40 mm: HR = 0.421, p < 0.001). Heads of 38 mm (HR = 1.288, p < 0.001) and 40 mm (HR = 1.367, p < 0.001) had increased risk of revision compared to the 28 mm head. CONCLUSION: Lumbar fusion surgery was associated with higher rate of hip prosthesis dislocation and higher risk of revision surgery. Femoral head component of 32 mm (or larger) associates with lower risk of dislocation in patients with previous lumbar fusion. Cite this article: Bone Joint J 2020;102-B(8):1003-1009.

RESUMO

Sarcomas are rare tumours arising from mesenchymal tissue. A multimodal management in an expert centre combining surgery and radiotherapy is the current standard of care for localized soft-tissue sarcomas of the extremities, to enable limb-sparing strategies. The delivery of pre- radiotherapy or postoperative radiotherapy offers similar local control and survival rates but the toxicity profile is quite different: preoperative radiotherapy increases the risk of wound complications and postoperative radiotherapy affects long-term functional outcomes. While postoperative radiotherapy has long been the rule, especially in Europe, technical improvements with image-guided- and intensity-modulated radiotherapy associated with a better management of postoperative wounds has tended to change practices with more frequent preoperative radiotherapy. More recently the possibilities of a hypofractionated regimen or potentiation by nanoparticles to increase the therapeutic index plead in favour of a preoperative delivery of radiotherapy. The aim of this paper is to report pros and cons of pre- and post-operative radiotherapy for soft-tissue sarcomas.

RESUMO

BACKGROUND: Heart Rate Variability (HRV) represents efferent vagus nerve activity which is suggested to be inversely related to fundamental mechanisms of tumorigenesis and to be a predictor of prognosis in various types of cancer. HRV is also believed to predict the occurrence and severity of post-operative complications. We aimed to determine the role of pre-operative HRV as a prognostic factor in overall and cancer free survival in patients with colorectal cancer. METHODS: Retrospective analysis was performed in a detailed dataset of patients diagnosed with primary colorectal cancer between January 2010 and December 2016, who underwent curative surgical treatment. HRV was measured as time-domain parameters (SDNN (Standard Deviation of NN-intervals) and RMSSD (Root Mean Square of Successive Differences)) based on pre-operative 10 second ECGs. Groups were created by baseline HRV: Low HRV (SDNN <20ms or RMSSD <19ms) and normal HRV (SDNN ≥20ms or RMSSD ≥19ms). Primary endpoints were overall and cancer free survival. RESULTS: A total of 428 patients were included in this study. HRV was not significantly associated with overall survival (SDNN <20ms vs SDNN ≥20ms:24.4% vs 22.8%, adjusted HR = 0.952 (0.607-1.493), p = 0.829; RMSSD <19ms vs RMSSD ≥19ms:27.0% vs 19.5%, adjusted HR = 1.321 (0.802-2.178), p = 0.274) or cancer recurrence (SDNN <20ms vs ≥20ms:20.1% vs 18.7%, adjusted HR = 0.976 (0.599-1.592), p = 0.924; RMSSD <19ms vs ≥19ms, 21.5% vs 16.9%, adjusted HR = 1.192 (0.706-2.011), p = 0.511). There was no significant association between HRV and CEA-level at one year follow-up, or between HRV and occurrence of a post-operative complication or the severity of post-operative complications. CONCLUSIONS: Heart rate variability was not associated with overall or cancer free survival in patients with primary colorectal cancer who underwent curative surgical treatment. These results do not align with results found in studies including only patients with advanced cancer, which suggests that there is only an association in the other direction, cancer causing low HRV.

RESUMO

Multiple surgical targets for treating obsessive-compulsive disorder with deep brain stimulation (DBS) have been proposed. However, different targets may modulate the same neural network responsible for clinical improvement. We analyzed data from four cohorts of patients (N = 50) that underwent DBS to the anterior limb of the internal capsule (ALIC), the nucleus accumbens or the subthalamic nucleus (STN). The same fiber bundle was associated with optimal clinical response in cohorts targeting either structure. This bundle connected frontal regions to the STN. When informing the tract target based on the first cohort, clinical improvements in the second could be significantly predicted, and vice versa. To further confirm results, clinical improvements in eight patients from a third center and six patients from a fourth center were significantly predicted based on their stimulation overlap with this tract. Our results show that connectivity-derived models may inform clinical improvements across DBS targets, surgeons and centers. The identified tract target is openly available in atlas form.

RESUMO

BACKGROUND: The aim of the present retrospective study was to evaluate the influence of preoperative right ventricular (RV) and tricuspid valve (TV) remodeling on the fate of tricuspid annuloplasty (TA) and right ventricle. METHODS: From May 2009 to December 2015, 423 patients who had undergone TA for functional tricuspid regurgitation (TR) were included in the study. Residual and recurrent TR were defined as moderate or more TR at discharge and follow-up, respectively. RV remodeling was defined as RV dysfunction and/or dilation. RESULTS: Residual TR after TA was recorded in 54 patients (13%). Five-year freedom from TR recurrence was 81% ± 3% in patients without residual TR and 41 ± 8 in patients with residual TR (P < .001). In patients without residual TR, the following risk factors for recurrent TR and late RV remodeling were identified: preoperative systolic pulmonary artery pressure, preoperative RV remodeling, severe preoperative TR or less than severe TR but with TV apparatus remodeling, and etiology of mitral regurgitation. Cox analysis with time-dependent variables confirmed TR recurrence (hazard ratio [HR]: 3.1) and late RV remodeling (HR: 6.5) as risk factors for lower survival. No protective effect of either flexible band or rigid ring TA compared with DeVega procedure was found. Similarly, preoperative atrial fibrillation and pacemaker dependency, late failure of mitral valve surgery did not affect the fate of TR. CONCLUSIONS: Prophylactic TA should be encouraged among surgeons. TA at the time of left-sided valve surgery should take into consideration not only annular size, but also tethering severity and RV remodeling.

RESUMO

Repair of medial meniscus posterior root tear (MMPRT) is considered as an effective early intervention strategy for osteoarthritis. We aimed at evaluating whether or not single-photon emission computed tomography/computed tomography (SPECT/CT) could predict the treatment outcome.Eleven patients with MMPRT who underwent preoperative SPECT/CT were retrospectively enrolled. Clinical symptoms were evaluated based on the knee injury and osteoarthritis outcome score (KOOS) and visual analogue scale (VAS) for pain. The uptake pattern of the medial tibial plateau (MTP) on SPECT/CT was visually assessed. Additionally, the maximum lesion-to-cortical counts ratio (LCRmax) for the anterior and posterior aspects of MTP and anterior-posterior MTP ratio (APR) were quantitatively assessed. Spearman correlation analyses were performed between the change in clinical symptom scores and preoperative SPECT/CT patterns.All patients showed increased radiotracer uptake in MTP. Among them, 8 (73%) showed dominant uptake in the anterior aspect of MTP. The rest 3 (27%) showed posterior-dominant uptake. Patients with anterior-dominant patterns tended to show better outcomes in terms of the postoperative KOOS score (P = .07). Anterior MTP LCRmax showed a negative correlation with the change in VAS (ρ = -0.664, P < .03). APR showed a correlation with the change in the KOOS score (ρ = 0.655, P < .03).Patients with MMPRT with relatively higher uptake in the anterior aspect of MTP could have better clinical outcomes after the repair. The preoperative SPECT/CT pattern may have a predictive value in selecting patients with good postoperative outcomes.

RESUMO

INTRODUCTION: Most symptomatic large-to-massive rotator cuff tears (RCTs) should be operated, but the surgical reparability depended on the degree of rotator cuff muscle atrophy or fatty infiltration. The orthopedic surgeons will decide whether the teared stump is reparable during the surgery, but preoperative evaluation can be done by some assessment tools. Magnetic resonance imaging (MRI) was used in recent studies to predict the reparability of large-to-massive RCTs, but the clinical availability was not as good as ultrasound. We hypothesize that the ultrasound elastography can predict the reparability of large-to-massive RCTs. METHODS: This is a prospective observational study and participants with large-to-massive RCTs who are going to have surgeries will be included. Out investigators will evaluate the shoulder passive range of motion (ROM) and strength of all participants. Participants' degree of shoulder pain and activities of daily living (ADLs) will be assessed by American Shoulder and Elbow Surgeons (ASES) score. The ultrasound elastography will be used to evaluate the tissue quality of supraspinatus muscle and infraspinatus muscle. To test the reliability of the ultrasound elastography, two physicians will perform the ultrasound elastography independently and twenty participants will be selected for the reliability test. Besides, MRI will be used to evaluate the size of tear, the degree of tendon retraction, fatty infiltration of rotator cuff muscles, and muscle atrophy. Finally, the orthopedic surgeons will perform surgeries and decide whether the teared stump can be completely repaired intraoperatively. The primary analysis is the predictive validity of ultrasound elastography for the reparability of large-to-massive RCTs. Before the predictive validity of ultrasound elastography is measured, our investigators will assess the reliability of ultrasound elastography when administered to cases with large-to-massive RCTs, and we will check the correlations between the findings of ultrasound elastography and MRI. DISCUSSION: The outcome will provide the evidence of ultrasound elastography for preoperative evaluation of large-to-massive RCTs. The relationships between the findings of ultrasound elastography and MRI will also be examined for further analysis. TRIAL REGISTRATION: Clinicaltrials.gov NCT03682679.

RESUMO

BACKGROUND: In the perioperative context, a frailty evaluation scale must consider certain characteristics such as validation, execution speed, simplicity, the capacity to measure multiple dimensions and not being dependent on a cognitive or physical test that could not be performed prior to surgery. The test should select patients that could benefit from interventions aimed to improve their postoperative outcomes. AIM: To validate two frailty evaluation scales for the perioperative period. MATERIAL AND METHODS: The Risk Analysis Index with local modifications (RAI-M) were applied to 201 patients aged 73 ± 7 years (49% women) and the Edmonton frailty scale were applied in 151 patients aged 73 ± 7 years (49% women) in the preoperative period. Their results were compared with the Rockwood frailty index. RESULTS: The Edmonton frail scale showed adequate psychometric properties and assessed multiple dimensions through 8 of the 11 original questions, achieving a discrimination power over 80% compared to the Rockwood Index. The RAI- M, demonstrated solid psychometric properties with a tool that examines 4 dimensions of frailty through 15 questions and reviewing the presence of 11 medical comorbidities. This scale had a discrimination power greater than 85% and it was significantly associated with prolongation of the planned hospital stay and mortality. CONCLUSIONS: RAI-M is a short and easily administered scale, useful to detect frailty in the preoperative period.
