Airway protection and outcomes after staged versus concurrent bilateral neck dissections with transoral base of tongue cancer resection. Head Neck 2024; 46:1020-1027. [PMID: 38414192 DOI: 10.1002/hed.27696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 12/30/2023] [Accepted: 02/08/2024] [Indexed: 02/29/2024] Open
Abstract
OBJECTIVES To assess airway, safety, and resource utilization outcomes between transoral base of tongue (BOT) surgery with staged versus concurrent bilateral neck dissections (BND). METHODS A retrospective cohort study of patients with human papilloma virus (HPV)-related BOT cancer who underwent transoral surgery and BND from January 2015 through June 2022 was conducted. Free flap patients were excluded. RESULTS Of 126 patients (46 [37%] staged and 80 [63%] concurrent BND), there were no significant differences in rates of postoperative intubation, tracheostomy, intensive care admission, operative takebacks, gastrostomy, and 30-day readmission. Total operative time (median difference 1.4 [95% CI 0.9-1.8] hours), length of stay (1.0 [1.0-1.0] day), and time between primary surgery and adjuvant therapy initiation (4.0 [0.0-8.0] days) were lower in the concurrent BND cohort. CONCLUSION Concurrent BND alongside transoral BOT resection is safe with similar airway outcomes and lower total operative time, length of stay, and time to adjuvant therapy initiation compared to staged BND.

Concurrent vs Staged Hybrid Ablation for Long-Standing Persistent Atrial Fibrillation: A Propensity-Matched Cohort Study. JACC Clin Electrophysiol 2024:S2405-500X(24)00160-9. [PMID: 38573292 DOI: 10.1016/j.jacep.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 02/16/2024] [Accepted: 02/21/2024] [Indexed: 04/05/2024]
Abstract
BACKGROUND Long-term success rates of catheter ablation (CA) for long-standing persistent atrial fibrillation (LSPAF) are less than satisfactory. Further improvement of ablation methods is crucial for enhancing the treatment of LSPAF. OBJECTIVE This study sought to compare the outcomes of concurrent vs staged minimally invasive surgical-catheter hybrid ablation for LSPAF. METHODS From December 2015 to December 2021, 104 matched patients (concurrent and staged, 1:1) were included in study. In the concurrent group, both left unilateral thoracoscopic epicardial ablation (EA) and CA were performed simultaneously in one procedure. In the staged group, EA was performed at the first hospitalization. If the patients experienced atrial fibrillation (AF) recurrence, CA was performed between 3 months and 1 year after EA. RESULTS In the concurrent group, 4 patients were restored to sinus rhythm after EA, and 41 were patients restored to sinus rhythm during CA; 86.5% (45 of 52) achieved intraprocedural AF termination during concurrent hybrid ablation. In the staged group, all 52 patients underwent staged CA because of the recurrence of AF or atrial tachycardia (AT). Forty-seven (90.4%) patients achieved intraprocedural AF or AT termination during CA. Freedom from AF or AT off antiarrhythmic drugs at 2 years after hybrid ablation was 79.9% ± 5.7% in the concurrent group and 86.0% ± 4.9% in the staged group (P = 0.390). Failure of intraprocedural AF termination (HR: 14.378) was an independent risk factor for AF recurrence after hybrid ablation. CONCLUSIONS Both concurrent and staged hybrid ablation could be safely and effectively applied to treat LSPAF. Improving the intraprocedural AF termination rate predicted better outcomes.

Abstract
Against the background of a lack of screening instruments for measuring depressive symptoms in Colombian adolescents and preadolescents, this study aims to establish the internal consistency reliability, component structure and the concurrent and discriminant validity of the Kutcher Adolescent Depression Six-Item Scale (KADS-6) among preadolescent school students in Sincelejo, Colombia. Participated 710 youth (10.8 years of age ± .75 years) divided into two groups to cross-validate analyses that were undertaken to determine the internal consistency reliability, as well as the concurrent and discriminant validity, of the KADS-6 among preadolescents. Results show that over 95% of the sample did not report problems understanding any of the items on the KADS-6. The KADS-6 had acceptable levels of internal consistency reliability, concurrent and discriminant validity and was unidimensional. In conclusion, The KADS-6 is well understood by Colombian preadolescents and has adequate psychometric properties in adolescents, rendering it acceptable for use with Colombian preadolescents.

[PMID: 37658764 DOI: 10.1002/alr.23262] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 08/24/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field. METHODS In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication. RESULTS The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention. CONCLUSION As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.

Abstract
Granulomatous mastitis (GM) is a rare inflammatory disorder that infrequently occurs with synchronous breast carcinoma. The present study reports the case of a patient who was initially diagnosed with recurrent GM, which eventually proved to be masking an underlying ductal carcinoma in situ (DCIS). A 30-year-old female presented with left breast pain. On clinical examination, there was a large, palpable and painful lump in the left breast, with axillary lymphadenopathy. Initially, the diagnosis was GM and conservative treatment was applied. Surgical resection was decided upon for the condition after it became recurrent, and the histopathological examination revealed extensive DCIS with GM. Later on, the patient underwent a mastectomy with an axillary sentinel lymph node biopsy. The postoperative follow-up was uneventful. In conclusion, tissue diagnosis has a key role in detecting DCIS masked by GM, especially in young females who are not undergoing regular mammogram screening. The present study shows the challenge that the specialists in this field may face when dealing with recurrent GM of the breast, and warns them to search for a second pathology such as the DCIS presented in the current case.

Comparative Analysis of Concurrent (CC), Mixed Flow (MX), and Combined Spray Drying Configurations on the Physicochemical Characteristics of Satsuma Mandarin ( Citrus unshiu) Juice Powders. Foods 2023; 12:3514. [PMID: 37761223 PMCID: PMC10530200 DOI: 10.3390/foods12183514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 09/14/2023] [Accepted: 09/18/2023] [Indexed: 09/29/2023] Open
Abstract
Satsuma mandarins are good sources of vitamin C and can be used as raw materials to produce novel plant-based food ingredients including satsuma mandarin juice powders (SJP). Food powders produced via spray drying often show thermal degradation due to the drying conditions and high drying air temperatures. The aim of this study was to evaluate the effect of using different spray drying configurations, including concurrent (CC), mixed flow (MX), and combined (CC + MX), at two inlet air temperatures (160 and 180 °C) on the physicochemical properties of SJP. Remarkably, SJP produced using the CC spray drying configuration exhibited a higher vitamin C content (3.56-4.01 mg/g) and lower moisture levels (15.18-16.35 g/100 g) than powders produced via MX or CC + MX. The vitamin C content of MX and CC + MX powders ranged from 2.88 to 3.33 mg/g. Meanwhile, all SJP had water activity values below 0.19. Furthermore, MX powders displayed the largest mean particle sizes (D50) (8.69-8.83 µm), higher agglomeration, and a rapid dissolution. Despite these differences, all SJP variants exhibited consistent color, surface area, and pore volumes. Notably, powders dried at higher inlet air temperatures (180 °C) showed less vitamin C content and increased thermal damage when compared with powders dried at 160 °C inlet air temperature. This study demonstrated the feasibility of producing high-quality SJP with an extended shelf life. SJP can be used as a novel plant-based ingredient in different food applications.

Complication rate of overlapping versus nonoverlapping functional and stereotactic surgery: a retrospective cohort study. J Neurosurg 2023; 138:1043-1049. [PMID: 36461842 PMCID: PMC10125844 DOI: 10.3171/2022.8.jns212363] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 08/03/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Overlapping surgery, in which one attending surgeon manages two overlapping operating rooms (ORs) and is present for all the critical portions of each procedure, is an important policy that improves healthcare access for patients and case volumes for surgeons and surgical trainees. Despite several studies demonstrating the safety and efficacy of overlapping neurosurgical operations, the practice of overlapping surgery remains controversial. To date, there are no studies that have investigated long-term complication rates of overlapping functional and stereotactic neurosurgical procedures. The primary objective of this study was to investigate the 1-year complication rates and OR times for nonoverlapping versus overlapping functional procedures. The secondary objective was to gain insight into what types of complications are the most prevalent and test for differences between groups. METHODS Seven hundred eighty-three functional neurosurgical cases were divided into two cohorts, nonoverlapping (n = 342) and overlapping (n = 441). The American Society of Anesthesiologists (ASA) scale score was used to compare the preoperative risk for both cohorts. A complication was defined as any surgically related reason that required readmission, reoperation, or an unplanned emergency department or clinic visit that required intervention. Complications were subdivided into infectious and noninfectious. Chi-square tests, independent-samples t-tests, and uni- and multivariable logistic regressions were used to determine significance. RESULTS There were no significant differences in mean ASA scale score (2.7 ± 0.6 for both groups, p = 0.997) or overall complication rates (8.8% nonoverlapping vs 9.8% overlapping, p = 0.641) between the two cohorts. Infections accounted for the highest percentage of complications in both cohorts (46.6% vs 41.8%, p = 0.686). There were no statistically significant differences between mean in-room OR time (187.5 ± 141.7 minutes vs 197.1 ± 153.0 minutes, p = 0.373) or mean open-to-close time (112.2 ± 107.9 minutes vs 121.0 ± 123.1 minutes, p = 0.300) between nonoverlapping and overlapping cases. CONCLUSIONS There was no increased risk of 1-year complications or increased OR time for overlapping functional and stereotactic neurosurgical procedures compared with nonoverlapping procedures.

A Two-Stage Voting-Boosting Technique for Ensemble Learning in Social Network Sentiment Classification. ENTROPY (BASEL, SWITZERLAND) 2023; 25:e25040555. [PMID: 37190343 PMCID: PMC10137704 DOI: 10.3390/e25040555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 03/15/2023] [Accepted: 03/21/2023] [Indexed: 05/17/2023]
Abstract
In recent years, social network sentiment classification has been extensively researched and applied in various fields, such as opinion monitoring, market analysis, and commodity feedback. The ensemble approach has achieved remarkable results in sentiment classification tasks due to its superior performance. The primary reason behind the success of ensemble methods is the enhanced diversity of the base classifiers. The boosting method employs a sequential ensemble structure to construct diverse data while also utilizing erroneous data by assigning higher weights to misclassified samples in the next training round. However, this method tends to use a sequential ensemble structure, resulting in a long computation time. Conversely, the voting method employs a concurrent ensemble structure to reduce computation time but neglects the utilization of erroneous data. To address this issue, this study combines the advantages of voting and boosting methods and proposes a new two-stage voting boosting (2SVB) concurrent ensemble learning method for social network sentiment classification. This novel method not only establishes a concurrent ensemble framework to decrease computation time but also optimizes the utilization of erroneous data and enhances ensemble performance. To optimize the utilization of erroneous data, a two-stage training approach is implemented. Stage-1 training is performed on the datasets by employing a 3-fold cross-segmentation approach. Stage-2 training is carried out on datasets that have been augmented with the erroneous data predicted by stage 1. To augment the diversity of base classifiers, the training stage employs five pre-trained deep learning (PDL) models with heterogeneous pre-training frameworks as base classifiers. To reduce the computation time, a two-stage concurrent ensemble framework was established. The experimental results demonstrate that the proposed method achieves an F1 score of 0.8942 on the coronavirus tweet sentiment dataset, surpassing other comparable ensemble methods.

Concurrent chemoradiotherapy followed by adjuvant chemotherapy versus concurrent chemoradiotherapy alone in locally advanced cervical cancer: A systematic review and meta-analysis. Front Oncol 2022; 12:997030. [PMID: 36568251 PMCID: PMC9768423 DOI: 10.3389/fonc.2022.997030] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Accepted: 11/21/2022] [Indexed: 12/12/2022] Open
Abstract
Objective This study aimed to assess the efficacy and safety of adjuvant chemotherapy (ACT) after concurrent chemoradiation (CCRT) in patients with locally advanced cervical cancer (LACC) via meta-analysis. Methods A systematic literature search of MEDLINE, PubMed, Web of Science, EMBASE, and the Cochrane Central Register of Controlled Trials was conducted from January 10, 1966 to May 20, 2022. Randomized controlled trials and observational studies comparing the CCRT alone with CCRT plus ACT were included. The literature search, quality assessment, and data extraction were conducted by two reviewers independently. The primary endpoints were 3-year rates of overall survival (OS) and progression-free survival (PFS). Complete response rate, local recurrence, distant metastasis, and adverse events were secondary outcomes. The hazard ratios (HRs) and relative risk (RR) were pooled. Results Nine studies with a total of 2732 patients were included in this meta-analysis, including 1411 patients in the CCRT group and 1321 in the CCRT plus ACT group. The HR for 3-year rates of OS and PFS of the CCRT group compared with the CCRT plus ACT group was 0.72 [95%confidence interval (CI) = 0.44-1.17] and 0.78 (95%CI = 0.5-1.75), respectively. No significant differences were observed between the two groups in the complete response rate (RR = 1.06, 95%CI = 0.96-1.16). However, local recurrence and distant metastasis were significantly lower in the CCRT plus ACT group than in the CCRT group (RR = 0.63, 95%CI = 0.44 -0.91 and RR = 0.64, 95%CI = 0.47-0.88). Grade 3-4 acute toxicities were more frequent in the CCRT plus ACT group (RR = 1.73, 95%CI =1.19-2.52). Conclusion Although associated with a decreased risk of local recurrence and distant metastasis, ACT did not significantly improve the survival rate and the complete response rate with increasing grade 3-4 acute toxicities in patients with LACC. Thus, this ACT regimen cannot be recommended for patients with LACC. Systematic review registration https://inplasy.com/inplasy-2022-9-0089/, identifier INPLASY202290089.

Global Coinfections with Bacteria, Fungi, and Respiratory Viruses in Children with SARS-CoV-2: A Systematic Review and Meta-Analysis. Trop Med Infect Dis 2022; 7:tropicalmed7110380. [PMID: 36422931 PMCID: PMC9698370 DOI: 10.3390/tropicalmed7110380] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/01/2022] [Accepted: 11/07/2022] [Indexed: 11/18/2022] Open
Abstract
Background: Coinfection with bacteria, fungi, and respiratory viruses has been described as a factor associated with more severe clinical outcomes in children with COVID-19. Such coinfections in children with COVID-19 have been reported to increase morbidity and mortality. Objectives: To identify the type and proportion of coinfections with SARS-CoV-2 and bacteria, fungi, and/or respiratory viruses, and investigate the severity of COVID-19 in children. Methods: For this systematic review and meta-analysis, we searched ProQuest, Medline, Embase, PubMed, CINAHL, Wiley online library, Scopus, and Nature through the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for studies on the incidence of COVID-19 in children with bacterial, fungal, and/or respiratory coinfections, published from 1 December 2019 to 1 October 2022, with English language restriction. Results: Of the 169 papers that were identified, 130 articles were included in the systematic review (57 cohort, 52 case report, and 21 case series studies) and 34 articles (23 cohort, eight case series, and three case report studies) were included in the meta-analysis. Of the 17,588 COVID-19 children who were tested for co-pathogens, bacterial, fungal, and/or respiratory viral coinfections were reported (n = 1633, 9.3%). The median patient age ranged from 1.4 months to 144 months across studies. There was an increased male predominance in pediatric COVID-19 patients diagnosed with bacterial, fungal, and/or viral coinfections in most of the studies (male gender: n = 204, 59.1% compared to female gender: n = 141, 40.9%). The majority of the cases belonged to White (Caucasian) (n = 441, 53.3%), Asian (n = 205, 24.8%), Indian (n = 71, 8.6%), and Black (n = 51, 6.2%) ethnicities. The overall pooled proportions of children with laboratory-confirmed COVID-19 who had bacterial, fungal, and respiratory viral coinfections were 4.73% (95% CI 3.86 to 5.60, n = 445, 34 studies, I2 85%, p < 0.01), 0.98% (95% CI 0.13 to 1.83, n = 17, six studies, I2 49%, p < 0.08), and 5.41% (95% CI 4.48 to 6.34, n = 441, 32 studies, I2 87%, p < 0.01), respectively. Children with COVID-19 in the ICU had higher coinfections compared to ICU and non-ICU patients, as follows: respiratory viral (6.61%, 95% CI 5.06−8.17, I2 = 0% versus 5.31%, 95% CI 4.31−6.30, I2 = 88%) and fungal (1.72%, 95% CI 0.45−2.99, I2 = 0% versus 0.62%, 95% CI 0.00−1.55, I2 = 54%); however, COVID-19 children admitted to the ICU had a lower bacterial coinfection compared to the COVID-19 children in the ICU and non-ICU group (3.02%, 95% CI 1.70−4.34, I2 = 0% versus 4.91%, 95% CI 3.97−5.84, I2 = 87%). The most common identified virus and bacterium in children with COVID-19 were RSV (n = 342, 31.4%) and Mycoplasma pneumonia (n = 120, 23.1%). Conclusion: Children with COVID-19 seem to have distinctly lower rates of bacterial, fungal, and/or respiratory viral coinfections than adults. RSV and Mycoplasma pneumonia were the most common identified virus and bacterium in children infected with SARS-CoV-2. Knowledge of bacterial, fungal, and/or respiratory viral confections has potential diagnostic and treatment implications in COVID-19 children.

Abstract
ABSTRACT In an attempt to protect the high-risk demographic and reduce burden on health care systems, concomitant administration of COVID-19 and influenza vaccines has been recommended by health bodies. The ComFluCOV trial indicates this is well tolerated with no reduction in immune response to either vaccine. A 48-year-old woman with right oropharyngeal squamous cell carcinoma underwent postradiotherapy FDG PET/CT, which demonstrated complete metabolic response. Incidental avid bilateral axillary lymphadenopathy of benign configuration was noted and concluded to be reactive in response to recent Pfizer-BioNTech booster and influenza vaccination. This is expected to be seen more frequently over the coming months.

RR Myelo POINT: A Retrospective Single-Center Study Assessing the Role of Radiotherapy in the Management of Multiple Myeloma and Possible Interactions with Concurrent Systemic Treatment. Cancers (Basel) 2022; 14:cancers14092273.

Abstract
Background and purpose: Although chemotherapy, biological agents, and radiotherapy (RT) are cornerstones of the treatment of multiple myeloma (MM), the literature regarding the possible interactions of concurrent systemic treatment (CST) and RT is limited, and the optimal RT dose is still unclear. Materials and methods: We retrospectively analyzed the records of patients who underwent RT for MM at our institution from 1 January 2005 to 30 June 2020. The data of 312 patients and 577 lesions (treated in 411 accesses) were retrieved. Results: Most of the treated lesions involved the vertebrae (60%) or extremities (18.9%). Radiotherapy was completed in 96.6% of the accesses and, although biologically effective doses assuming an α/β ratio of 10 (BED 10) > 38 Gy and CST were significantly associated with higher rates of toxicity, the safety profile was excellent, with side effects grade ≥2 reported only for 4.1% of the accesses; CST and BED 10 had no impact on the toxicity at one and three months. Radiotherapy resulted in significant improvements in performance status and in a pain control rate of 87.4% at the end of treatment, which further increased to 96.9% at three months and remained at 94% at six months. The radiological response rate at six months (data available for 181 lesions) was 79%, with only 4.4% of lesions in progression. Progression was significantly more frequent in the lesions treated without CST or BED 10 < 15 Gy, while concurrent biological therapy resulted in significantly lower rates of progression. Conclusion: Radiotherapy resulted in optimal pain control rates and fair toxicity, regardless of BED 10 and CST; the treatments with higher BED 10 and CST (remarkably biological agents) improved the already excellent radiological disease control.

[PMID: 35458991 PMCID: PMC9028061 DOI: 10.3390/s22083006] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 04/01/2022] [Accepted: 04/11/2022] [Indexed: 02/04/2023]
Abstract
Real-time biomechanical feedback (BMF) is a relatively new area of research. The potential of using advanced technology to improve motion skills in sport and accelerate physical rehabilitation has been demonstrated in a number of studies. This paper provides a literature review of BMF systems in sports and rehabilitation. Our motivation was to examine the history of the field to capture its evolution over time, particularly how technologies are used and implemented in BMF systems, and to identify the most recent studies showing novel solutions and remarkable implementations. We searched for papers in three research databases: Scopus, Web of Science, and PubMed. The initial search yielded 1167 unique papers. After a rigorous and challenging exclusion process, 144 papers were eventually included in this report. We focused on papers describing applications and systems that implement a complete real-time feedback loop, which must include the use of sensors, real-time processing, and concurrent feedback. A number of research questions were raised, and the papers were studied and evaluated accordingly. We identified different types of physical activities, sensors, modalities, actuators, communications, settings and end users. A subset of the included papers, showing the most perspectives, was reviewed in depth to highlight and present their innovative research approaches and techniques. Real-time BMF has great potential in many areas. In recent years, sensors have been the main focus of these studies, but new types of processing devices, methods, and algorithms, actuators, and communication technologies and protocols will be explored in more depth in the future. This paper presents a broad insight into the field of BMF.

Factors Affecting Patients with Concurrent Deep Neck Infection and Lemierre's Syndrome. Diagnostics (Basel) 2022; 12:diagnostics12040928. [PMID: 35453976 PMCID: PMC9029513 DOI: 10.3390/diagnostics12040928] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 11/20/2022] Open
Abstract
Deep neck infection (DNI) is a severe disease affecting the deep neck spaces, and is associated with an increased risk of airway obstruction. Lemierre’s syndrome (LS) refers to septic thrombophlebitis of the internal jugular vein after pharyngeal infection, and is linked with high morbidity and mortality. Both diseases begin with an oropharyngeal infection, and concurrence is possible. However, no studies have examined the risk factors associated with co-existence of LS and DNI. Accordingly, this study examined a patient population to investigate the risk factors associated with concurrent DNI and LS. We examined data from a total of 592 patients with DNI who were hospitalized between May 2016 and January 2022. Among these patients, 14 had concurrent DNI and LS. The relevant clinical variables were assessed. In a univariate analysis, C-reactive protein (odds ratio (OR) = 1.004, 95% CI: 1.000−1.009, p = 0.045), involvement of multiple spaces (OR = 23.12, 95% CI: 3.003−178.7, p = 0.002), involvement of the carotid space (OR = 179.6, 95% CI: 22.90−1409, p < 0.001), involvement of the posterior cervical space (OR = 42.60, 95% CI: 12.45−145.6, p < 0.001) and Fusobacterium necrophorum (F. necrophorum, OR = 288.0, 95% CI: 50.58−1639, p < 0.001) were significant risk factors for concurrent DNI and LS. In a multivariate analysis, involvement of the carotid space (OR = 94.37, 95% CI: 9.578−929.9, p < 0.001), that of the posterior cervical space (OR = 24.99, 95% CI: 2.888−216.3, p = 0.003), and F. necrophorum (OR = 156.6, 95% CI: 7.072−3469, p = 0.001) were significant independent risk factors for concurrent LS in patients with DNI. The length of hospitalization in patients with concurrent LS and DNI (27.57 ± 14.94 days) was significantly longer than that in patients with DNI alone (10.01 ± 8.26 days; p < 0.001), and the only pathogen found in significantly different levels between the two groups was F. necrophorum (p < 0.001). Involvement of the carotid space, that of the posterior cervical space and F. necrophorum were independent risk factors for the concurrence of DNI and LS. Patients with concurrent LS and DNI had longer hospitalization periods than patients with DNI alone. Furthermore, F. necrophorum was the only pathogen found in significantly different levels in DNI patients with versus those without LS.

A Pilot Study Comparing the Effects of Concurrent and Terminal Visual Feedback on Standing Balance in Older Adults. SENSORS 2022; 22:s22082826. [PMID: 35458811 PMCID: PMC9033013 DOI: 10.3390/s22082826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 03/24/2022] [Accepted: 03/29/2022] [Indexed: 11/16/2022]
Abstract
While balance training with concurrent feedback has been shown to improve real-time balance in older adults, terminal feedback may simplify implementation outside of clinical settings. Similarly, visual feedback is particularly well-suited for use outside the clinic as it is relatively easily understood and accessible via ubiquitous mobile devices (e.g., smartphones) with little additional peripheral equipment. However, differences in the effects of concurrent and terminal visual feedback are not yet well understood. We therefore performed a pilot study that directly compared the immediate effects of concurrent and terminal visual feedback as a first and necessary step in the future design of visual feedback technologies for balance training outside of clinical settings. Nineteen healthy older adults participated in a single balance training session during which they performed 38 trials of a single balance exercise including trials with concurrent, terminal or no visual feedback. Analysis of trunk angular position and velocity features recorded via an inertial measurement unit indicated that sway angles decreased with training regardless of feedback type, but sway velocity increased with concurrent feedback and decreased with terminal feedback. After removing feedback, training with either feedback type yielded decreased mean velocity, but only terminal feedback yielded decreased sway angles. Consequently, this study suggests that, for older adults, terminal visual feedback may be a viable alternative to concurrent visual feedback for short duration single-task balance training. Terminal feedback provided using ubiquitous devices should be further explored for balance training outside of clinical settings.

[PMID: 35910822 PMCID: PMC9336604 DOI: 10.4103/jgid.jgid_279_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 11/07/2021] [Accepted: 11/22/2021] [Indexed: 11/10/2022] Open
Abstract
Introduction: Co-infection with different agents such as bacterial, viral, and Rickettsia is being increasingly recognized due to greater availability and utilization of the diagnostic tests among malaria patients. Methods: Consecutive admitted malarial cases were included and were subjected to test for general investigations, bacteria, typhoid, dengue, chikungunya, and rest for specific diagnosis. All patients were followed up till discharge or death and appropriate statistical tests were performed. Results: A total of 152 malaria patients were recruited and 27 (18.8%) had concurrent infections. It included 40.7% dengue only, 18.7% pneumonia, 11.1% urinary tract infection (UTI), 7.4% enteric fever, 3.7% leptospirosis, chikungunya, and tuberculous meningitis each, and 3.7% each of dengue with pneumonia and UTI. The organisms isolated were Streptococcus pneumoniae, Klebsiella pneumoniae, Escherichia coli, Salmonella typhi, and Mycobacterium tuberculosis. The mean duration of fever was 6.33 ± 3.63 days with a range of 3–20 days. Blood culture grew in 2 cases S. typhi and K. pneumonia,e. Dengue co-infections had significantly higher clinical and laboratory features of dengue and complications such as bleeding, jaundice, and cholecystitis, whereas rest concurrent infections had a significantly higher proportion of nausea and vomiting, convulsion, altered sensorium, productive cough, urinary symptoms, shock, acute kidney injury, anemia, and mean neutrophil count. There was significantly higher mortality among malaria–dengue concurrent infection group with 2 (15.4%) than malaria mono-infection group 3 (2.4%). Conclusion: Co-infections with malaria are not uncommon, especially dengue fever and other bacterial infections. The dominant clinical picture is of the superimposed infection. Decision should be clinically guided adjunct with specific diagnostic tests, and timely treatment has favorable outcome.

Targeted therapies for unresectable stage III non-small cell lung cancer. MEDIASTINUM (HONG KONG, CHINA) 2022; 5:22.

Abstract
Until recently, the standard treatment in unresectable stage III non-small cell lung cancer was concurrent chemoradiotherapy, but often with dismal outcome. The introduction of consolidation treatment with immune checkpoint inhibitors has shifted the treatment landscape and prognosis of these patients. However, patients whose tumors harbors an epidermal growth factor receptor (EGFR) mutation derived less benefit, with an increased risk of immune-related adverse events. Moreover, current data suggested that patients with oncogenic addicted tumors, mainly EGFR-positive tumors, and also anaplastic lymphoma kinase (ALK)-positive have poorer progression free survival after chemoradiotherapy. Indeed, these tumors have also inferior distant control compared with those who have wild-type disease, especially in the central nervous system, highlighting the need for assessing the role of targeted therapies in this patient population. It is speculated that outcome could probably increase with a consolidation treatment strategy including an EGFR tyrosine kinase inhibitor. However, a personalized treatment approach is not considered standard of care in this setting due to lack of robust evidence, as the majority of trials were performed in unselected patients, number of patients is limited and the majority of these studies were underpowered. In this review we summarize the role of tyrosine kinase inhibitors in unresectable stage III NSCLC, specifically focusing on EGFR-mutant tumors.

The association between viral load and concurrent human papillomavirus infection at the genital and anal sites of young women and the impact of vaccination. Tumour Virus Res 2021; 13:200233. [PMID: 34958987 PMCID: PMC8732794 DOI: 10.1016/j.tvr.2021.200233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 12/17/2021] [Accepted: 12/17/2021] [Indexed: 11/22/2022] Open
Abstract
Concurrent genital-anal human papillomavirus (HPV) infections may impose an increased anal cancer risk in women with HPV-related genital lesions. High viral load may facilitate genital-anal HPV concurrence. Genital and anal HPV is reduced by a bivalent HPV16/18 vaccine, yet the effect on concurrent genital-anal HPV remains unclear. This study analyzed viral load in concurrent genital-anal HPV infections, relative to genital-only and anal-only HPV infections and the impact of vaccination in young women. We included 1074 women, who provided both genital and anal swabs. HPV detection and genotyping was performed using the SPF10-DEIA-LiPA25. HPV copy numbers were measured with type-specific qPCRs and corrected for cellular content to obtain the viral load. Concurrent genital-anal HPV often had significantly higher genital viral load (0.09–371 c/cell) than genital-only HPV (3.17E-04-15.9 c/cell, p < 0.0001 to p < 0.05). Moreover, nearly all concurrent genital-anal HPV types had higher genital copy numbers per PCR reaction (157-416E04 c/rxn) than anal copy numbers (0.90–884E01 c/rxn, p < 0.0001 to p < 0.001). Vaccinated women had significantly less infections with HPV16/18 vaccine-types (2.8% vs 13.7%, p < 0.0001) and HPV31/35/45 cross-protective types (7.4% vs 21.1%, p < 0.0001) than unvaccinated women. In conclusion, particularly high genital viral load is found in concurrent genital-anal HPV infections, which are effectively reduced by vaccination. Concurrent genital-anal HPV infections may impose a higher risk of anal cancer. These infections have increased genital viral load. The genital site is likely the main source of a concurrent genital-anal HPV infection. Vaccination effectively reduces concurrent genital-anal HPV infections.

Concurrent and overlapping surgery: perspectives from surgeons on spinal posterior instrumented fusion for adolescent idiopathic scoliosis. J Child Orthop 2021; 15:589-595. [PMID: 34987670 PMCID: PMC8670537 DOI: 10.1302/1863-2548.15.210142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Accepted: 11/05/2021] [Indexed: 02/03/2023] Open
Abstract
PURPOSE The purpose of this study was to determine perspectives of surgeons regarding simultaneous surgery in patients undergoing posterior spine instrumentation and fusion (PSIF) for adolescent idiopathic scoliosis (AIS). METHODS A survey was administered to orthopaedic trainees and faculty regarding simultaneous surgery for primary PSIF for AIS. A five-point Likert scale (1: 'Strongly Disagree' to 5: 'Strongly Agree') was used to assess agreement with statements about simultaneous surgery. We divided simultaneous surgery into concurrent, when critical portions of operations occur at the same time, and overlapping, when noncritical portions occur at the same time. RESULTS The 72 respondents (78.3% of 92 surveyed) disagreed with concurrent surgery for 'one of my patients' (response mean 1.76 (sd 1.03)) but were more accepting of overlapping surgery (mean 3.94 (sd 0.99); p < 0.0001). The rating difference between concurrent and overlapping surgery was smaller for paediatric and spine surgeons (-1.25) than for residents or those who did not identify a subspecialty (-2.17; p = 0.0246) or other subspecialty surgeons (-2.57; p = 0.0026). Respondents were more likely to agree with explicit informed consent for concurrent surgery compared with overlapping (mean 4.32 (sd 0.91) versus 3.44 (sd 1.14); p < 0.001). CONCLUSION Orthopaedic surgeons disagreed with concurrent but were more accepting of overlapping surgery and anaesthesia for PSIF for AIS. Respondents were in greater agreement that patients should be explicitly informed of concurrence than of overlap. The surgical community's evidence and position regarding simultaneous surgery, in particular overlapping, must be more effectively presented to the public in order to bridge the gap in perspectives.

Abstract
Acute promyelocytic leukemia (APL) is a type of acute myeloid leukemia characterized by predominating abnormal promyelocytes with a PML-RARA rearrangement or a variant thereof. BCR-ABL1 rearrangement is an oncogenic event that is usually associated with chronic myeloid leukemia but also occurs in both acute lymphoblastic and acute myeloid leukemias and in healthy individuals. However, APL with concurrent PML-RARA and BCR-ABL1 rearrangements has rarely been reported. Herein, we describe a patient with APL exhibiting a BCR-ABL1 rearrangement in a minor clone and discuss the importance of evaluating this genetic alteration in terms of pathogenesis and treatment.

Abstract
International schizophrenia guidelines endorse seeking the patient's preference for guiding antipsychotic therapy. There exists a small niche of patients who prefer, or are required to use, long-acting injectable antipsychotic medications due to the adherence benefit. However, they may not be able to achieve adequate symptom reduction prior to experiencing treatment-limiting adverse effects from a single agent. Here, we present a patient case prescribed concurrent long-acting injectable antipsychotic therapy with paliperidone palmitate and aripiprazole monohydrate due to patient preference in the setting of a history of nonadherence to oral medications, treatment-limiting adverse effects to long-acting injectable paliperidone, and failure to achieve adequate symptom reduction with long-acting injectable aripiprazole monotherapy.

Continued versus Interrupted Targeted Therapy during Metastasis-Directed Stereotactic Radiotherapy: A Retrospective Multi-Center Safety and Efficacy Analysis. Cancers (Basel) 2021; 13:cancers13194780.

Abstract
Simple Summary The increasing use of targeted therapy (TT) has resulted in prolonged disease control and survival in many metastatic cancers. In parallel, stereotactic radiotherapy (SRT) is increasingly performed in patients receiving TT to obtain a durable control of resistant metastases, and thereby to prolong the time to disseminated disease progression and switch of systemic therapy. The aim of this study was to analyze the safety and efficacy of SRT combined with TT in metastatic cancer patients and to assess the influence of continuous vs. interrupted TT during metastasis-directed SRT. The data of 454 SRTs in 158 patients from the international multicenter database (TOaSTT) on metastatic cancer patients treated with SRT and concurrent TT (within 30 days) were analyzed. We found that there was no significant difference in survival, progression, or severe toxicity, whether TT was interrupted during SRT or not. Although any-grade acute and late SRT-related toxicity occurred in 63 (40%) and 52 (33%) patients, severe SRT-related toxicity rates were low (3% and 4%, respectively). The highest toxicity rates were observed for the combination of SRT and EGFRi or BRAF/MEKi, and any grade of toxicity was significantly increased when EGFRi or BRAF/MEKi were continued during SRT. However, this did not account for severe toxicity. Abstract The increasing use of targeted therapy (TT) has resulted in prolonged disease control and survival in many metastatic cancers. In parallel, stereotactic radiotherapy (SRT) is increasingly performed in patients receiving TT to obtain a durable control of resistant metastases, and thereby to prolong the time to disseminated disease progression and switch of systemic therapy. The aims of this study were to analyze the safety and efficacy of SRT combined with TT in metastatic cancer patients and to assess the influence of continuous vs. interrupted TT during metastasis-directed SRT. The data of 454 SRTs in 158 patients from the international multicenter database (TOaSTT) on metastatic cancer patients treated with SRT and concurrent TT (within 30 days) were analyzed using Kaplan–Meier and log rank testing. Toxicity was defined by the CTCAE v4.03 criteria. The median FU was 19.9 mo (range 1–102 mo); 1y OS, PFS and LC were 59%, 24% and 84%, respectively. Median TTS was 25.5 mo (95% CI 11–40). TT was started before SRT in 77% of patients. TT was interrupted during SRT in 44% of patients, with a median interruption of 7 (range 1–42) days. There was no significant difference in OS or PFS whether TT was temporarily interrupted during SRT or not. Any-grade acute and late SRT-related toxicity occurred in 63 (40%) and 52 (33%) patients, respectively. The highest toxicity rates were observed for the combination of SRT and EGFRi or BRAF/MEKi, and any-grade toxicity was significantly increased when EGFRi (p = 0.016) or BRAF/MEKi (p = 0.009) were continued during SRT. Severe (≥grade 3) acute and late SRT-related toxicity were observed in 5 (3%) and 7 (4%) patients, respectively, most frequently in patients treated with EGFRi or BRAF/MEKi and in the intracranial cohort. There was no significant difference in severe toxicity whether TT was interrupted before and after SRT or not. In conclusion, SRT and continuous vs. interrupted TT in metastatic cancer patients did not influence OS or PFS. Overall, severe toxicity of combined treatment was rare; a potentially increased toxicity after SRT and continuous treatment with EGFR inhibitors or BRAF(±MEK) inhibitors requires further evaluation.

Concurrent use of nivolumab and radiotherapy for patients with metastatic non-small cell lung cancer and renal cell carcinoma with oligometastatic disease progression on nivolumab. Mol Clin Oncol 2021; 15:214.

Abstract
Checkpoint inhibitors (CPIs), such as nivolumab, have transformed the treatment paradigm for patients with metastatic non-small cell lung cancer (mNSCLC) and metastatic renal cell carcinoma (mRCC). The combination of CPIs and radiotherapy (RT) constitutes a multimodal treatment approach that may work synergistically and facilitate augmented systemic responses. The aim of the present retrospective study was to assess the efficacy and safety of continuation of nivolumab treatment with the addition of RT in patients with mNSCLC and mRCC who develop oligometastatic disease progression on single-agent nivolumab. All patients with mNSCLC and mRCC who received nivolumab at the Department of Oncology, Prince Sultan Military Medical City (Riyadh, Saudi Arabia) between November 2016 and April 2018 were identified. The records of patients who developed oligometastatic disease progression during nivolumab treatment and were subsequently treated with RT, with nivolumab continued beyond disease progression, were retrospectively reviewed. Details of RT, clinical outcomes and toxicity data were collected. Of the 96 patients who received nivolumab, 22 received multiple courses of RT. A total of 39 sites were irradiated: Bone (n=15), lung (n=9), brain (n=8), adrenal gland (n=2), renal bed (n=2), skin (n=1), ethmoid sinus (n=1) and scalp (n=1). Partial response and complete response were noted at 25 (64%) and 3 (8%) sites, respectively. Stable disease was noted at 6 sites (15%) and disease progression was noted at 5 sites (13%). The median time on nivolumab from the date of the first fraction of RT was 4.5 months (range, 1.5-29 months) for patients with mNSCLC and 5 months (range, 1-38.5 months) for patients with mRCC. No patients developed grade 3-4 toxicities. Grade 2 pneumonitis was noted in 3 patients receiving lung RT. The addition of RT appeared to initiate a response and prolong the duration of nivolumab treatment. Therefore, the combination of nivolumab and RT was found to be well tolerated, with response rates exceeding those in published studies of nivolumab monotherapy.

Abstract
58 cases of metastatic sarcoma were reviewed retrospectively in order to compare the efficacy and safety of concurrent (n=24, group A) versus sequential (n=34, group B) use of chemotherapy and targeted therapy in metastatic sarcoma. Progression-free survival (PFS) 1 was defined as the duration between initiation of first-line treatment to disease progression or recurrence. PFS' was defined as the duration between initiation of first-line treatment to the failure of chemotherapy and targeted therapy, and overall survival (OS) was defined as the duration between initiation of first-line treatment to the date of last follow-up or death. The results revealed that patients in group A possessed a higher tumor burden compared to those in group B (P=0.049). Survival curves revealed that the median PFS1 (15.2 vs. 5.4 months, P=0.000), median PFS' (15.2 vs. 10.8 months, P=0.049), and median OS (42.3 vs. 25.3 months, P=0.041) of subjects in group A were remarkably longer than those of group B. Subgroup analysis showed that patients in group A experienced more favorable PFS1 (15.2 vs. 3 months, P=0.000), PFS' (15.2 vs. 5.8 months, P=0.003), and OS (35.2 vs. 15.7 months, P=0.011) than those in group B, with findings especially prominent in patients with tumor burden ≥ 10 cm in comparison to patients with tumor burden < 10 cm (P ≥ 0.05). All grades of leukopenia, thrombocytopenia, fatigue, and oral mucositis were more frequently diagnosed in patients of group A compared to those of group B. However, there were no significant differences between the rates of Grade 3-4 adverse events between the two groups. This investigation suggests that the concurrent use of targeted therapy and chemotherapy may be useful and safe as a first-line treatment in patients with metastatic sarcoma who possess a high tumor burden.

Abstract
Background: Coinfection with bacteria, fungi, and respiratory viruses in SARS-CoV-2 is of particular importance due to the possibility of increased morbidity and mortality. In this meta-analysis, we calculated the prevalence of such coinfections. Methods: Electronic databases were searched from 1 December 2019 to 31 March 2021. Effect sizes of prevalence were pooled with 95% confidence intervals (CIs). To minimize heterogeneity, we performed sub-group analyses. Results: Of the 6189 papers that were identified, 72 articles were included in the systematic review (40 case series and 32 cohort studies) and 68 articles (38 case series and 30 cohort studies) were included in the meta-analysis. Of the 31,953 SARS-CoV-2 patients included in the meta-analysis, the overall pooled proportion who had a laboratory-confirmed bacterial infection was 15.9% (95% CI 13.6–18.2, n = 1940, 49 studies, I2 = 99%, p < 0.00001), while 3.7% (95% CI 2.6–4.8, n = 177, 16 studies, I2 = 93%, p < 0.00001) had fungal infections and 6.6% (95% CI 5.5–7.6, n = 737, 44 studies, I2 = 96%, p < 0.00001) had other respiratory viruses. SARS-CoV-2 patients in the ICU had higher co-infections compared to ICU and non-ICU patients as follows: bacterial (22.2%, 95% CI 16.1–28.4, I2 = 88% versus 14.8%, 95% CI 12.4–17.3, I2 = 99%), and fungal (9.6%, 95% CI 6.8–12.4, I2 = 74% versus 2.7%, 95% CI 0.0–3.8, I2 = 95%); however, there was an identical other respiratory viral co-infection proportion between all SARS-CoV-2 patients [(ICU and non-ICU) and the ICU only] (6.6%, 95% CI 0.0–11.3, I2 = 58% versus 6.6%, 95% CI 5.5–7.7, I2 = 96%). Funnel plots for possible publication bias for the pooled effect sizes of the prevalence of coinfections was asymmetrical on visual inspection, and Egger’s tests confirmed asymmetry (p values < 0.05). Conclusion: Bacterial co-infection is relatively high in hospitalized patients with SARS-CoV-2, with little evidence of S. aureus playing a major role. Knowledge of the prevalence and type of co-infections in SARS-CoV-2 patients may have diagnostic and management implications.

Is the Concurrent Use of Sorafenib and External Radiotherapy Feasible for Advanced Hepatocellular Carcinoma? A Meta-Analysis. Cancers (Basel) 2021; 13:2912. [PMID: 34200809 PMCID: PMC8230463 DOI: 10.3390/cancers13122912] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 06/07/2021] [Accepted: 06/09/2021] [Indexed: 02/07/2023] Open
Abstract
We evaluate the feasibility of a concurrent application of sorafenib and external beam radiation therapy (EBRT) for advanced hepatocellular carcinoma (HCC). PubMed, Embase, Medline, and Cochrane Library were searched up to 9 April 2021. The primary endpoint was grade ≥3 complications, and the secondary endpoint was overall survival (OS). Subgroup analyses were performed for studies with the EBRT targets, intrahepatic vs. non-intrahepatic lesions (e.g., extrahepatic metastases or malignant vessel involvement only). Eleven studies involving 512 patients were included in this meta-analysis. Pooled rates of gastrointestinal, hepatologic, hematologic, and dermatologic grade ≥3 toxicities were 8.1% (95% confidence interval (CI): 4.8-13.5, I2 = ~0%), 12.9% (95% CI: 7.1-22.1, I2 = 22.4%), 9.1% (95% CI: 3.8-20.3, I2 = 51.3%), and 6.8% (95% CI: 3.8-11.7, I2 = ~0%), respectively. Pooled grade ≥3 hepatologic and hematologic toxicity rates were lower in studies targeting non-intrahepatic lesions than those targeting intrahepatic lesions (hepatologic: 3.3% vs. 17.1%, p = 0.041; hematologic: 3.3% vs. 16.0%, p = 0.078). Gastrointestinal and dermatologic grade ≥3 complications were not significantly different between the subgroups. Regarding OS, concurrent treatment was more beneficial than non-concurrent treatment (odds ratio: 3.3, 95% CI: 1.3-8.59, p = 0.015). One study reported a case of lethal toxicity due to tumor rupture and gastrointestinal bleeding. Concurrent treatment can be considered and applied to target metastatic lesions or local vessel involvement. Intrahepatic lesions should be treated cautiously by considering the target size and hepatic reserve.

Safety and efficacy of concurrent carboplatin during full-dose craniospinal irradiation for high-risk/metastatic medulloblastoma in a resource-limited setting. Pediatr Blood Cancer 2021; 68:e28925. [PMID: 33533557 DOI: 10.1002/pbc.28925] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 01/08/2021] [Accepted: 01/10/2021] [Indexed: 11/10/2022]
Abstract
PURPOSE To assess the safety and efficacy of concurrent carboplatin during craniospinal irradiation (CSI) in high-risk/metastatic medulloblastoma defined as either residual tumor >1.5 cm2 or leptomeningeal metastases. METHODS This single-arm combined prospective (2005-2011) and retrospective (2011-2019) study was undertaken at a tertiary care cancer center in India. Following surgery, patients with newly diagnosed high-risk/metastatic medulloblastoma received concurrent carboplatin (35 mg/m2 ) for 15 days (day 1 to day 15) during CSI plus posterior fossa/tumor bed boost, followed by six cycles of standard adjuvant chemotherapy. RESULTS All 97 patients completed their planned course of radiotherapy without interruptions, except for two (2.1%) patients who had brief gaps due to treatment-related toxicity. Grade 3-4 anemia, neutropenia, thrombocytopenia, and febrile neutropenia were seen in four (4.1%), 41 (42.2%) 21 (21.6%), and 18 (18.6%) patients, necessitating packed cell transfusion, granulocyte colony-stimulating factor, and platelet support in five (5.1%), 41 (42.2%), and five (5.1%) patients, respectively, during the concurrent phase. Following myelorecovery, 92 (94.9%) patients completed the planned six cycles of standard adjuvant systemic chemotherapy. There were no treatment-related deaths during the concurrent chemo-radiotherapy phase, while three (3.1%) toxic deaths were ascribed to adjuvant chemotherapy-related complications. At a median follow-up of 82 months, the 5-year Kaplan-Meier estimates of progression-free survival and overall survival were 60.2% and 62.1%, respectively. On univariate analysis, leptomeningeal metastases (M0/M1 vs. M2/M3) and histological subtype (large cell/anaplastic vs. others) emerged as significant prognostic factors for survival. CONCLUSION Addition of concurrent carboplatin to RT as radiosensitizing chemotherapy is a simple and effective way of treatment intensification in high-risk/metastatic medulloblastoma.

Why Concurrent CDDP and Radiotherapy Has Synergistic Antitumor Effects: A Review of In Vitro Experimental and Clinical-Based Studies. Int J Mol Sci 2021; 22:ijms22063140. [PMID: 33808722 PMCID: PMC8003508 DOI: 10.3390/ijms22063140] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 03/08/2021] [Accepted: 03/17/2021] [Indexed: 01/17/2023] Open
Abstract
Chemo-radiotherapy, which combines chemotherapy with radiotherapy, has been clinically practiced since the 1970s, and various anticancer drugs have been shown to have a synergistic effect when used in combination with radiotherapy. In particular, cisplatin (CDDP), which is often the cornerstone of multi-drug combination cancer therapies, is highly versatile and frequently used in combination with radiotherapy for the treatment of many cancers. Therefore, the mechanisms underlying the synergistic effect of CDDP and radiotherapy have been widely investigated, although no definitive conclusions have been reached. We present a review of the combined use of CDDP and radiotherapy, including the latest findings, and propose a mechanism that could explain their synergistic effects. Our hypothesis involves the concepts of overlap and complementation. “Overlap” refers to the overlapping reactions of CDDP and radiation-induced excessive oxidative loading, which lead to accumulating damage to cell components, mostly within the cytoplasm. “Complementation” refers to the complementary functions of CDDP and radiation that lead to DNA damage, primarily in the nucleus. In fact, the two concepts are inseparable, but conceptualizing them separately will help us understand the mechanism underlying the synergism between radiation therapy and other anticancer drugs, and help us to design future radiosensitizers.

Abstract
Salmonella enterica serotype Enteritidis (Salmonella Enteritidis) is a major cause of foodborne disease outbreaks worldwide. In 2018, two concurrent outbreaks of Salmonella Enteritidis gastroenteritis in one district of South Africa were investigated. We describe the use of whole-genome sequencing (WGS) analysis of bacterial isolates to assist with the investigation of these outbreaks. Outbreak A affected children (n=27) attending a day-care centre, while outbreak B affected adults (n=16) who ate breakfast at the same restaurant. Salmonella Enteritidis was isolated from stool samples in both outbreaks (four children in outbreak A; 12 restaurant customers and three restaurant food-handlers in outbreak B). In outbreak B, Salmonella Enteritidis was isolated from three food retention samples (raw chicken egg, hollandaise sauce and rocket-herb). Available isolates from both outbreaks (n=13) were investigated using WGS analysis. Sequencing data for isolates were analysed at the EnteroBase web-based platform and included core-genome multi-locus sequence typing (cgMLST). Isolates with epidemiological links to the restaurant (n=10) and day-care centre (n=3), were shown by cgMLST to be highly genetically related, with no more than five allele differences when comparing one isolate against another. On food history, eggs and hollandaise sauce were the common food items consumed by ill restaurant customers. Unfortunately, Salmonella Enteritidis isolated from the egg and hollandaise sauce were not available for WGS analysis. Our investigation concluded that the two concurrent outbreaks were caused by a highly related strain of Salmonella Enteritidis, suggesting the possibility of a common contaminated food source, of which contaminated eggs are strongly implicated.

Description of parallel and sequential configurations for concurrent therapeutic plasma exchange and continuous kidney replacement therapy in adults. J Clin Apher 2020; 36:211-218.

Abstract
Therapeutic plasma exchange (TPE) and continuous kidney replacement therapy (CKRT) are extracorporeal therapeutic procedures often implemented in management of patients. Critically ill patients may be afflicted with disease processes that require both TPE and CKRT. Performing TPE discontinuous with CKRT is technically easier, however, it disrupts CKRT and may compromise with CKRT efficiency or hemofilter life. Concurrent TPE with CKRT offers several advantages including simultaneous control of disease process and correction of electrolyte, fluid, and acid-base disturbances that may accompany TPE. Additionally, TPE may be performed by either centrifugation method or membrane plasma separation method. The technical specifications of these methods may influence the methodology of concurrent connections. This report describes and reviews two different approaches to circuit arrangements when establishing concurrent TPE and CKRT.

Abstract
OBJECTIVES To evaluate the safety and efficacy of stereotactic radiotherapy (SRT) in patients with metastatic renal cell carcinoma (mRCC) concurrently receiving targeted therapy (TT) or immunotherapy. PATIENTS AND METHODS Data on patients with mRCC were extracted from a retrospective international multicentre register study (TOaSTT), investigating SRT concurrent (≤30 days) with TT/immune checkpoint inhibitor (ICI) therapy. Overall survival (OS), progression-free survival (PFS), local metastasis control (LC) and time to systemic therapy switch were analysed using Kaplan-Meier curves and log-rank testing. Clinical and treatment factors influencing survival were analysed using multivariate Cox regression. Acute and late SRT-induced toxicity were defined according to the Common Terminology Criteria for Adverse Events v.4.03. RESULTS Fifty-three patients who underwent 128 sessions of SRT were included, of whom 58% presented with oligometastatic disease (OMD). ICIs and TT were received by 32% and 68% of patients, respectively. Twenty patients (37%) paused TT for a median (range) of 14 (2-21) days. ICI therapy was not paused in any patient. A median (range) of 1 (1-5) metastatic tumour was treated per patient, with a median (range) SRT dose of 65 (40-129.4) Gy (biologically effective dose). The OS, LC and PFS rates at 1 year were 71%, 75% and 25%, respectively. The median OS and PFS were not significantly different among patients receiving TT vs those receiving ICIs (P = 0.329). New lesions were treated with a repeat radiotherapy course in 46% of patients. After 1 year, 62% of patients remained on the same systemic therapy as at the time of SRT; this was more frequent for ICI therapy compared to TT (83% vs 36%; P = 0.035). OMD was an independent prognostic factor for OS (P = 0.004, 95% confidence interval [CI] 0.035-0.528) and PFS (P = 0.004; 95% CI 0.165-0.717) in multivariate analysis. Eastern Cooperative Oncology Group performance status (ECOG-PS) was the other independent prognostic factor for OS (P = 0.001, 95% CI 0.001-0.351). Acute grade 3 toxicity was observed in two patients, and late grade 3 toxicity in one patient. No grade 4 or 5 toxicity was observed. CONCLUSION Combined treatment with TT or immunotherapy and concurrent SRT was safe, without signals of increased severe toxicity. As we observed no signal of excess toxicity, full-dose SRT should be considered to achieve optimal metastasis control in patients receiving TT or immunotherapy. Favourable PFS and OS were observed for patients with oligometastatic RCC with a good ECOG-PS, which should form the basis for prospective testing of this treatment strategy in properly designed clinical trials.

Abstract
In patients with specific dermatologic disorders who are affected by new corona virus, we know little about disease course (underlying disease and new onset infection), and the most proper management strategies include both issues that are what this systematic review targets. Databases of PubMed, Scopus, Google Scholar, Medscape, and Centre of Evidence-Based Dermatology, coronavirus dermatology resource of Nottingham University searched completely up to May 15, 2020, and initial 237 articles were selected to further review and finally 9 articles (including 12 patients) entered to this study. From 12 patients with chronic underlying dermatologic disease treated with systemic therapies, only 1 patient required Intensive Care Unit admission, the others have been treated for mild-moderate symptoms with conventional therapies. The biologic or immunosuppressive/immunomodulator agents have been ceased during the course of disease. The course of coronovirus diseases 2019 (COVID-19) and its management was as similar as normal populations. Their underlying dermatologic disease were exacerbating from mild to moderate. Their treatment has been continued as before, after the symptoms improved. Exacerbation of patients underlying dermatologic disease was mild to moderate. Discontinuing the treatment in the acute period of COVID and the restart after recovery may prevent severe recurrence and disturbing cytokine storms in these patients.

A Deep Machine Learning Method for Concurrent and Interleaved Human Activity Recognition. SENSORS (BASEL, SWITZERLAND) 2020; 20:E5770.

Abstract
Human activity recognition has become an important research topic within the field of pervasive computing, ambient assistive living (AAL), robotics, health-care monitoring, and many more. Techniques for recognizing simple and single activities are typical for now, but recognizing complex activities such as concurrent and interleaving activity is still a major challenging issue. In this paper, we propose a two-phase hybrid deep machine learning approach using bi-directional Long-Short Term Memory (BiLSTM) and Skip-Chain Conditional random field (SCCRF) to recognize the complex activity. BiLSTM is a sequential generative deep learning inherited from Recurrent Neural Network (RNN). SCCRFs is a distinctive feature of conditional random field (CRF) that can represent long term dependencies. In the first phase of the proposed approach, we recognized the concurrent activities using the BiLSTM technique, and in the second phase, SCCRF identifies the interleaved activity. Accuracy of the proposed framework against the counterpart state-of-art methods using the publicly available datasets in a smart home environment is analyzed. Our experiment's result surpasses the previously proposed approaches with an average accuracy of more than 93%.

Abstract
Auditory feedback is a simple, low-cost training solution that can be used in rehabilitation, motor learning, and performance development. The use has been limited to the instruction of a single kinematic or kinetic target. The goal of this study was to determine if auditory feedback could be used to simultaneously train 2 lower-extremity parameters to perform a bodyweight back squat. A total of 42 healthy, young, recreationally active males participated in a 4-week training program to improve squat biomechanics. The Trained group (n = 22) received 4 weeks of auditory feedback. Feedback focused on knee flexion angle and center of pressure under the foot at maximum squat depth. The Control group (n = 20) performed squats without feedback. Subjects were tested pre, post, and 1 week after training. The Trained group achieved average target knee flexion angle within 1.73 (1.31) deg (P < .001) after training and 5.36 (3.29) deg (P < .01) at retention. While achieving target knee flexion angle, the Trained group maintained target center of pressure (P < .001). The Control group improved knee range of motion, but were not able to achieve both parameter targets at maximum squat depth (P < .90). Results from this study demonstrate that auditory feedback is an effective way to train 2 independent biomechanical targets simultaneously.

Abstract
Chronic lymphocytic leukemia (CLL) patients are at an increased risk for developing more aggressive lymphomas via Richter's transformation and of developing secondary malignancies. Despite the known association for secondary cancers, oropharyngeal cancers occur rarely. We present a case of a woman with a history of CLL who presented to our facility via transfer for impending airway compromise. Her initial workup was consistent with CLL; however, biopsies were taken of the neck mass because of its aggressive nature. She was treated with rituximab with good response. Final pathology showed evidence of CLL and tonsillar squamous cell carcinoma (SCC). Direct laryngoscopy and further biopsies yielded a diagnosis of unresectable oropharyngeal SCC. She was to be treated with chemotherapy and radiation for her SCC while holding treatment for CLL. This case demonstrates a rare and unexpected concurrent diagnosis.

Abstract
Anaplastic thyroid cancer (ATC) is a rare, but extremely aggressive, form of cancer with a high mortality rate. Differentiated thyroid cancer (DTC), on the other hand, including papillary and follicular subtypes, are relatively common and typically follows a more indolent course. Cases have been reported in which ATC transforms from DTC, and where DTC and ATC exist simultaneously. Given the low incidence of such cases, they have not been well studied, and the optimal treatment regimen has yet to be determined. We present a case of a 77-year-old woman who was initially presented with papillary thyroid cancer (PTC) with focal ATC. Five months after undergoing total thyroidectomy, she returned with a new right sided neck mass. Fine needle aspiration (FNA) with biopsies of the mass and lymph node at one level revealed a smear pattern consistent with ATC. However, lymph node biopsy taken from a different level revealed a smear pattern consistent with PTC. Mutation analysis was performed and results were positive for metastatic BRAF V600- mutant ATC. The patient was then started on dabrafenib/trametinib chemotherapy. Seven months later, she was tolerating treatment well. These unique clinical features including the initial presentation and the relatively favorable survival, that is more than double that of the median survival rate for ATC, suggests that those with synchronous PTC and ATC may have a more indolent course with better prognosis than those with ATC alone. It is also possible that the relatively longer survival in our patient is due to the use of the BRAF inhibitor, dabrafenib and the MEK inhibitor, trametinib in this case with concurrent ATC and PTC. While patients with both PTC and ATC have been documented to have mutations in the BRAF V600 gene, the objective of this report is to present the relatively favorable outcomes when a therapeutic regimen is guided by mutation analysis. Future research into advanced treatment options including targeted therapy and/or immunotherapy for both DTC and ATC is needed. Somatic mutation testing may also be helpful to identify oncogenic kinase abnormalities that will inform therapeutic decision making.

Abstract
Objective: Planning, a higher order executive functioning ability important for accomplishing complex everyday tasks, can be differentiated into initial and concurrent (online) planning. In this study, initial plans were codified to assess their impact on task execution. Cognitive correlates of initial planning and task execution were also examined.Method: One-hundred fifty-four community dwelling older adults completed a naturalistic task, called the Day Out Task (DOT), in either a planning or no planning condition. The DOT required participants to multitask and efficiently complete a series of eight subtasks, preparing for a hypothetical day out. Participants also completed a neuropsychological battery with the following cognitive constructs assessed: processing speed, cognitive flexibility, episodic memory, visuoconstructional abilities, and working memory and sequencing.Results: There were no significant differences between the planning and no planning conditions in DOT execution accuracy, efficiency or duration. However, efficiency of the initial plan was a significant predictor of task execution efficiency and initial plans that contained a higher amount of Task Relevant Associations predicted a shorter duration of task execution after controlling for age, processing speed and episodic memory. Furthermore, initial plans that had more Task Relevant Associations and task executions that took less time were associated with better working memory and sequencing ability.Discussion: Quality of the initial plan is important. Initial plans that organize task objectives in an efficient manner may lead to better task execution efficiency, while initial plans that demonstrate a detailed understanding of individual relational aspects of the tasks (i.e., higher rate of Task Relevant Associations) may result in faster task execution.

Abstract
Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) are standard of care for pediatric choledocholithiasis. Patients typically undergo separate procedures during hospitalization. Collaboration between surgical and gastroenterology services led to performance of both procedures concurrently during one anesthetic. We hypothesized that concurrent procedures would reduce costs without increasing complications as compared with separate procedures. Materials and Methods: We evaluated patients admitted to our institution from 2013 to 2018 with choledocholithiasis who underwent both ERCP and LC during the same admission. Fourteen patients underwent both procedures during concurrent anesthetic. Forty-two patients who underwent LC and ERCP under separate anesthetics were randomly selected to perform a 3:1 matched case-control study. Demographic and clinical data were collected, including imaging and laboratory findings, outcomes, and costs. Comparative analysis was completed with Fisher's exact and Mann-Whitney U tests. Results: On presentation, there was no difference in common bile duct size, total bilirubin, or white blood cell count between the concurrent and separate procedure cohorts. Significantly, there was no difference in total length of anesthesia (117.9 ± 40 minutes versus 119.6 ± 52 minutes, P = .747). There were also no differences in complications, emergency department visits, or readmissions. Patients who underwent concurrent procedures had significantly lower total cost of stay ($45,597 ± 11,513 versus $61,008 ± 17,960, P = .006). Conclusions: In pediatric patients with choledocholithiasis, performing LC and ERCP may be performed concurrently during one anesthetic, which decreases costs without increasing in anesthesia time or complications.

[PMID: 29920857 DOI: 10.1111/adb.12637] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2017] [Revised: 04/24/2018] [Accepted: 04/25/2018] [Indexed: 12/13/2022]
Abstract
Restricting when and where smoking can occur is a major focus of public health policies in Western countries. In conjunction with increased taxation, these approaches have contributed to a reduction in smoking uptake among adolescents, yet the consequences for established smokers are less clear. In order to further explore this relationship, we developed a novel animal model of restricted nicotine self-administration. Rats were trained to choose between three doses of nicotine (15, 30 and 60 μg/kg/infusion) under conditions where nicotine was (1) freely available at a low cost (20-second post-infusion time-out, fixed-ratio 1 [FR1]), (2) available under restricted access at a low cost (300-second post-infusion time-out, FR1), or (3) freely available at a high cost (20-second post-infusion time-out, FR5). We demonstrate that as access to nicotine is restricted or when cost increases, rats compensate for these changes by increasing their intake of the highest dose of nicotine available. This preference was impervious to treatment with the smoking cessation medication varenicline, but was reduced when the cost of the highest dose only was increased, or when nicotine was again made freely available at a low cost. These results provide the first evidence in rats that nicotine availability and cost influence nicotine choice independently of variations in nicotine and context exposure. They imply that established smokers may compensate for changes in the availability and cost of tobacco by increasing their rate of smoking when they are free to do so.

Abstract
Spinal epidural abscess (SEA) presents with vertebral body involvement. SEA is mostly pyogenic in developed countries, but in developing countries, tuberculosis is more common cause. Young female presented with fever, neck, and right upper limb pain for 1 month followed by acute onset weakness in the right upper limb. Magnetic resonance imaging study of cervical spine showed contrast-enhancing lesion in C2-C3 epidural region. Surgery-aided by initiation of antibacterial and antitubercular treatment based on culture and histopathological study of pus helped us to get good clinical outcome. One should always keep in mind possibility of tubercular abscess while treating cases of spinal epidural lesions, though it is rare in the absence of osseous involvement. Pyogenic and tubercular abscess can present concurrently and sending pus for culture and sensitivity is must as it plays important role in identifying dual organisms.

Concurrent Micronutrient Deficiencies Are Low and Micronutrient Status Is Not Related to Common Health Indicators in Ghanaian Women Expecting to Become Pregnant. Curr Dev Nutr 2019; 3:nzz053. [PMID: 31187085 PMCID: PMC6554457 DOI: 10.1093/cdn/nzz053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Revised: 04/10/2019] [Accepted: 04/15/2019] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Micronutrients are important for reproductive health and pregnancy, but the status of multiple vitamins and minerals is rarely measured in women before pregnancy. OBJECTIVES We aimed to assess the status and concurrent deficiencies of micronutrients among women before pregnancy and their relation with common health indicators. METHODS This was a cross-sectional study that recruited women who expected to become pregnant within the next 6 mo in Asesewa, Ghana, a semi-urban community. Women self-reported demographics and health history. We measured blood pressure, height, and weight and conducted a blood draw and hemoglobin assessment (n = 98). We measured serum/plasma concentrations of ferritin, iron, total iron binding capacity, zinc, copper, retinol, and 25-hydroxyvitamin D, in addition to markers of inflammation. We used established cutoffs for deficiency and insufficiency/low status for each micronutrient after adjusting ferritin, zinc, and retinol for inflammation. We compared biomarker distributions by common health indicators. RESULTS Forty percent of women had overweight/obesity, 33% were anemic, and 23% had elevated blood pressure. Overall, 27% had ≥1 deficiencies, whereas only 4% had 2 deficiencies. Fifty-eight percent of women had ≥1 insufficiencies and 18% had ≥2 insufficiencies. Prevalence of individual deficiencies was 12%, 7%, 7%, 4%, and 0% and prevalence of individual insufficiencies was 18%, 12%, 29%, 13%, and 13% for iron, copper, vitamin A, zinc, and vitamin D, respectively. Iron biomarkers and retinol concentrations differed by anemia status, and copper was higher in those with elevated blood pressure. Micronutrient concentrations were not associated with self-reported medical history (parity or history of anemia, malaria, or night blindness). CONCLUSIONS In Asesewa, Ghana, there was a relatively low prevalence of individual micronutrient deficiencies, but the majority of women were insufficient in ≥1 micronutrients. Iron and vitamin A status was lower in those with anemia, but otherwise, micronutrient status did not relate to common health markers.

Concurrent neoadjuvant chemotherapy and estrogen deprivation in patients with estrogen receptor-positive, human epidermal growth factor receptor 2-negative breast cancer (CBCSG-036): A randomized, controlled, multicenter trial. Cancer 2019; 125:2185-2193. [PMID: 30892700 DOI: 10.1002/cncr.32057] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2018] [Revised: 01/17/2019] [Accepted: 01/22/2019] [Indexed: 12/22/2022]
Abstract
BACKGROUND The current randomized, controlled, multicenter clinical trial was conducted to investigate the efficacy of concurrent neoadjuvant chemotherapy (NCT) and estrogen deprivation in patients with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer. METHODS Eligible patients with AJCC stage IIB to stage IIIC, ER-positive, HER2-negative breast cancer were enrolled and randomly assigned to receive NCT with or without estrogen deprivation. The primary endpoint was the objective response rate (ORR). RESULTS A total of 249 patients were assigned to either neoadjuvant chemoendocrine therapy (NCET) (125 patients) or the NCT group (124 patients). In the intention-to-treat analysis, the ORR was found to be significantly higher in the NCET group compared with the NCT group (84.8% vs 72.6%; odds ratio, 2.11 [95% CI, 1.13-3.95; P = .02). The efficacy of NCET was more prominent in tumors with a higher Ki-67 index (>20%), with an ORR of 91.2% reported in the NCET group versus 68.7% in the NCT group (P = .001). The pathologic complete response and pathological response rates did not differ significantly between the 2 groups. Although there was no significant difference with regard to progression-free survival (PFS) between the 2 groups (P = .188), patients with a higher baseline Ki-67 index appeared to derive a greater PFS benefit from NCET (2-year PFS rate of 91.5% in the NCET group vs 76.5% in the NCT group; P = .058). Adding endocrine agents to NCT did not result in significant differences in adverse events (grade 3 or 4; graded according to National Cancer Institute Common Terminology Criteria for Adverse Events [version 3.0]) between the 2 groups. CONCLUSIONS The addition of estrogen deprivation to NCT appears to improve the clinical response in patients with ER-positive, HER2-negative breast cancer, especially for those individuals with a higher Ki-67 index. Patients with a higher Ki-67 index might derive more PFS benefit from concurrent neoadjuvant treatment.

Abstract
BACKGROUND Distal radius fracture (DRF) is a common fracture of the upper extremity. The role of concurrent injuries in patients treated for DRFs is poorly elucidated. The authors sought to determine whether remote injuries were associated with worse outcomes after management of DRFs. METHODS A retrospective cohort study including all consecutively seen patients by a university hospital hand service between 2010 and 2015. Preoperative radiographs were analyzed, and patients were managed by surgeon preference and evaluated postoperatively using pain scores. Remote injury was defined as any other injury sustained at the time of fracture not localized to affected extremity. Univariate analysis was performed to identify factors associated with risk of complication. A multivariate logistic regression analysis was performed, controlling for confounding factors. RESULTS A total of 181 DRFs in 176 patients were treated over the 5-year period of the study. Forty-eight (26.5%) of the fractures were managed nonoperatively with casting, 12 (6.6%) with closed reduction and pinning, and 119 (65.7%) with open reduction and plating. The mean follow-up was 5.2 months. The complication rate was 18.2%. The most common complication was persistent pain in 5 patients, followed by median neuropathy, loss of reduction, arthritis, and distal radioulnar joint instability. After controlling for age, body mass index, hand surgeon, and other confounders, remote injury was associated with a significantly increased risk of complications ( P = .04, odds ratio: 6.03, 95% confidence interval: 1.05-34.70). CONCLUSIONS Patients with remote injuries have a 6-fold increased risk of complications after DRF treatment. The additional risk in these patients should be considered during patient/family counseling and clinical decision-making in DRF management.

Abstract
STUDY DESIGN Prospective cross-sectional survey. OBJECTIVE To determine the perspectives of parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis (AIS) regarding simultaneous surgery and trainee participation. SUMMARY OF BACKGROUND DATA Simultaneous ("at the same time") surgery is under scrutiny by the public, government, payers, and the medical community. The objective of this study is to determine the perspectives of parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis. Our goal is to inform the national conversation on this subject with real patient and family voices. METHODS A survey was prospectively administered to 31 consecutive parents of patients undergoing posterior instrumented fusion for adolescent idiopathic scoliosis at a large academic medical center. "Overlapping" was defined as simultaneity during "noncritical" parts of an operation. "Concurrent" was defined as simultaneity that includes "critical" part(s) of an operation. Participants were asked to provide levels of agreement with overlapping and concurrent surgery and anesthesia, as well as with trainee involvement. RESULTS On average, respondents "strongly agree" with the need to be informed about overlapping or concurrent surgery. They "disagree" with both overlapping and concurrent scheduling, and "disagree" with trainees operating without direct supervision, even for "noncritical" parts. Informing parents about the presence of a back-up surgeon or research demonstrating safety of simultaneous surgery did not make them agreeable to simultaneous scheduling. CONCLUSION Parents have a strong desire to be informed of simultaneous spinal surgery and anesthesia as part of consent on behalf of their children. Their disagreement with simultaneous surgery, as well as with trainees operating without direct supervision, suggests discordance with current guidelines and practice and should inform the national conversation moving forward. LEVEL OF EVIDENCE N/A.

Comparison of outcomes between hip fracture patients with concurrent upper limb injuries and patients with an isolated hip fracture. ANZ J Surg 2018; 89:57-60. [PMID: 30497096 DOI: 10.1111/ans.14942] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 09/15/2018] [Accepted: 09/28/2018] [Indexed: 11/30/2022]
Abstract
BACKGROUND Concurrent upper limb injuries can occur with hip fractures, and its incidence and effect on outcomes are unclear. The objective of this study was to review the number and types of upper limb injuries sustained by patients with hip fractures, and investigate how acute hospital stay, rehabilitation and patient outcomes are affected. METHODS A retrospective study was performed on 820 patients with traumatic fracture of the hip over the age of 50. We reviewed the patients with concurrent upper limb injuries and compared patient outcomes - including mortality, acute length of stay in the orthopaedic ward, rehabilitation outcomes and rehabilitation length of stay. RESULTS Thirty-four patients (4.1%) with a hip fracture had a concurrent upper limb injury. Patients with and without concurrent upper limb injuries had similar acute length of stays on the orthopaedic ward (mean 5.2 versus 5.5 days, P = 0.4), and no significant difference in mortality rates at time of discharge (0% versus 3.8%, P = 0.4) and at 30 days (2.9% versus 9.1%, P = 0.2). However, they also required significantly longer rehabilitation (mean 34.6 versus 19.9 days, P = 0.009) even after other demographic factors including upper limb injury, older age and dementia were taken into consideration (multivariate linear model: concurrent upper limb injury, P = 0.0003; older age, P = 0.05; dementia, P = 0.09). CONCLUSION A concurrent upper limb injury is infrequent in the hip fracture population. Overall, these patients were previously higher functioning than the average hip fracture patient and required longer stays in inpatient rehabilitation than patients with isolated hip fractures.

Abstract
To examine the outcomes of concurrent versus sequential whole-brain radiotherapy (WBRT) and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in nonsmall cell lung cancer (NSCLC) patients with EGFR mutation.Retrospectively 105 patients with NSCLC, brain metastasis, and EGFR mutation (Affiliated Hospital of Guangdong Medical University, 01/2011 to 12/2014) were grouped as: EGFR-TKIs alone (n = 39, group A), EGFR-TKIs + concurrent radiotherapy (n = 34, group B), and radiotherapy followed by EGFR-TKIs (n = 32, group C).The intracranial objective response rates of groups A, B, and C were 66.7%, 85.3%, and 75%, respectively (P < .05). The median intracranial progression-free survival of groups A, B, and C were 6.8, 12.4, and 9.1 months, respectively (P < .05). The median extracranial progression-free survival of groups A, B, and C were 7.8, 9.4, and 8.3 months, respectively (P > .05).EGFR-TKIs and WBRT by simultaneous application improved the short- and long-term benefits to patients with NSCLC brain metastasis carrying EGFR mutation compared to concurrent application or EGFR-TKIs alone without additional adverse events.
