Arthrocentesis versus non-surgical intervention as initial treatment for temporomandibular joint arthralgia: a randomized controlled trial with long-term follow-up

alexandrossfakianakis shared this article with you from Inoreader Arthrocentesis versus non-surgical intervention as initial treatment for temporomandibular joint arthralgia: a randomized controlled trial with long-term follow-up via International Journal of Oral and Maxillofacial Surgery via MedWorm.com Arthrocentesis for arthralgia of the temporomandibular joint (TMJ) is often only indicated when conservative, non-surgical interventions have failed. However, performing arthrocentesis as initial therapy may facilitate earlier and better recuperation of the joint. The aim of this study was to assess the efficacy of this therapy with a long-term follow-up. Eighty-four patients were randomly allocated to receive either arthrocentesis as initial treatment (n  = 41) or non-surgical intervention (n = 43).

Clinical Outcomes and Economic Burden of Seasonal Influenza and Other Respiratory Virus Infections in Hospitalized Adults

alexandrossfakianakis shared this article with you from Inoreader Clinical Outcomes and Economic Burden of Seasonal Influenza and Other Respiratory Virus Infections in Hospitalized Adults via Journal of Medical Virology ABSTRACT Background The cost of influenza and other respiratory virus infections should be determined to analyze the real burden of these diseases. We aimed to investigate the clinical outcomes and cost of illness due to respiratory virus infections in hospitalized adult patients. Methods Hospitalized patients who had nasal swab sampling for a suspected viral infection between 1 August 2018 to 31 March 2019 were included. Outcome variables were oxygen requirement, mechanical ventilation need, intensive care unit admission and cost. Results At least one viral pathogen was detected in 125 (47.7%) of 262 patients who were included in the study. Fifty-five (20.9%) of the patients were infected with influenza. Influenza-positive patients had higher rates for respiratory support, intensive care unit admission and mortality compared to all other patients. The average cost of hospitalization per person was 2,879.76 USD in the influenza-negative group, while the same cost was 3,274.03 USD in the influenza-positive group. Although all of the vaccinated influenza-positive patients needed oxygen support, neither of them required invasive mechanical ventilation or intensive care unit admission. The average hospitalization cost per person was 779.70 USD in the vaccinated group compared to 3,762.01 USD in the unvaccinated group. Disease-related direct cost of influenza in the community was estimated as 22,776,075.61 USD in the 18-65 years of age group and 15,756,120.02 USD in the 65 years of age and over group per year. Conclusion Influenza, compared to other respiratory virus infections, can lead to untoward clinical outcomes and mortality as well as higher direct medical costs in adults.

The T‐shaped FST pharyngoplasty step‐by‐step closure technique

alexandrossfakianakis shared this article with you from Inoreader The T‐shaped FST pharyngoplasty step‐by‐step closure technique via Head & Neck Abstract Pharyngocutaneous fistula is one of the most common and serious complications associated with total laryngectomy. Numerous studies tried to evaluate causative and predisposing factors associated with this complication, but data are considerably variable and there is still no international consensus. Incidence rate varies considerably between studies, with reported rates from 3% to 65%. This 4K video presents our T-shaped four-step technique (FST) for closing the pharyngeal mucosa after total laryngectomy in a step-by-step manner. All sutures were performed by braided absorbable 3/0 26 mm 1/2c (Vicryl plus 3.0; Ethicon, Somerville, NJ, USA). Recordings were performed using a Karl Storz 4K 3D VITOM® exoscope (Karl Storz SE & Co. KG, Tuttlingen, Germany). We have been described this technique through a high-definition video, showing each step, and tips from the authors. Our T-shaped pharyngoplasty closure technique can be divided into four steps: 1. "Key Stitches"; 2. "A rea Refinement Stitches"; 3. "Modified Connell Suture"; 4. "Modified Purse String Suture." Our T-shaped FST closure technique proved to be an effective and reproducible method, which we feel could be the preferred choice for primary pharyngoplasty closure. View on Web

Immunomodulatory fibrous hyaluronic acid‐Fmoc‐diphenylalanine‐based hydrogel induces bone regeneration

alexandrossfakianakis shared this article with you from Inoreader Immunomodulatory fibrous hyaluronic acid‐Fmoc‐diphenylalanine‐based hydrogel induces bone regeneration via Journal of Clinical Periodontology Abstract Aim To investigate the potential of an ultra-short aromatic peptide hydrogelator integrated with hyaluronic acid (HA) to serve as a scaffold for bone regeneration. Materials and methods Fluorenylmethyloxycarbonyl-diphenylalanine (FmocFF)/HA hydrogel was prepared and characterized using microscopy and rheology. Osteogenic differentiation of MC3T3-E1 preosteoblasts was investigated using Alizarin red, alkaline phosphatase and calcium deposition assays. In vivo, 5-mm diameter calvarial critical-sized defects were prepared in 20 Sprague-Dawley rats and filled with either FmocFF/HA hydrogel, deproteinized bovine bone mineral, FmocFF/Alginate (Alg) hydrogel or left unfilled. 8 weeks following implantation, histology and micro-CT analyses were performed. Immunohistochemistry was performed in 6 rats to assess the hydrogel's immunomodulatory effect. Results A nanofibrous FmocFF/HA hydrogel with a high storage modulus of 46KPa was prepared. It supported osteogenic differentiation of MC3T3-E1 preosteoblasts and facilitated calcium deposition. In vivo, the hydrogel implantation resulted in approximately 93% bone restoration. It induced bone deposition not only around the margins, but also generated bony islets along the defect. Elongated M2 macrophages lining at the periosteum-hydrogel interface were observed 1 week after implantation. After 3 weeks, these macrophages were dispersed through the regenerating tissue surrounding the newly formed bone. Conclusion FmocFF/HA hydrogel can serve as a cell-free, biomimetic, immunomodulatory scaffold for bone regeneration. This article is protected by copyright. All rights reserved. View on Web

Quantification of Vocal Fold Atrophy in Age‐Related and Parkinson's Disease‐Related Vocal Atrophy

alexandrossfakianakis shared this article with you from Inoreader Quantification of Vocal Fold Atrophy in Age‐Related and Parkinson's Disease‐Related Vocal Atrophy via The Laryngoscope In this study, features of vocal fold atrophy were quantified and compared across dysphonia severity and between age-related and Parkinson's disease-related vocal atrophy. The results support an association between vocal fold bowing and dysphonia severity based on CAPE-V scores, and demonstrate that patients with Parkinson's-related atrophy have more significant bowing compared to those with age-related vocal atrophy. Objective Vocal fold atrophy (VFA) is associated with aging and Parkinson's disease (PD). Clinical diagnosis of VFA depends on several visual-perceptual laryngostroboscopy findings that are inherently subjective. The purpose of this study was to use quantitative measurements to; (1) examine the relationships between VFA and dysphonia severity and (2) evaluate differences in VFA in patients with age-related VFA versus PD. Methods Thirty-six patients >60 years of age with VFA were included in this retrospective cohort study. Demographic information, medical history, Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), Voice Handicap Index-10 (VHI-10), and still images from the stroboscopic exam were obtained. Image J™ was used to measure VFA, including bowing index (BI), normalized glottal gap area, and normalized mucosal wave amplitude. Pearson's correlation was used to evaluate the relationship between VFA, CAPE-V, and VHI-10. t-Tests and multivariate linear regression were used to compare VFA measures by dysphonia severity (CAPE-V <30 vs. >30) and diagnosis (age-related vocal atrophy [ARVA] and PD). Results BI was positively correlated with CAPE-V. Patients with CAPE-V >30 had a significantly larger BI compared to those with CAPE-V <30. Patients with PD had significantly larger BI than those with ARVA. Diagnosis of PD also predicted a larger BI after controlling for age and CAPE-V. Conclusion Quantitative measures supported an association between bowing severity and dysphonia severity in patients with PD and ARVA. A PD diagnosis significantly predicted more severe BI. These findings demonstrate the potential utility of BI. Quantitative VFA measures might also provide insight into the mechanisms of ARVA and dysphonia.

Vertebral fractures assessed by dual-energy X-ray absorptiometry and all-cause mortality. The Tromsø Study 2007-2020

alexandrossfakianakis shared this article with you from Inoreader Vertebral fractures assessed by dual-energy X-ray absorptiometry and all-cause mortality. The Tromsø Study 2007-2020 via American Journal of Epidemiology - Advance Access Abstract Vertebral fractures have been associated with increased mortality, but findings are inconclusive, and many vertebral fractures avoid clinical attention. We investigated this association in a general population of 2476 older adults aged ≥55 years from Tromsø, Norway, who were followed over 2007-2020, using dual-energy X-ray absorptiometry (DXA) at baseline to evaluate vertebral fractures (mild, moderate, severe). We used multiple Cox regression models to estimate hazard ratios (HRs) for all-cause mortality, adjusted for age, sex, body mass index, education, smoking, alcohol intake, cardiovascular disease and respiratory disease. Mean follow-up in the cohort was 11.2±2.7 years. 341 participants (13.8%) had one or more vertebral fractures at baseline, and 636 participants (25.7%) died between baseline and follow-up. Fully adjusted models showed a non-significant association between vertebral fracture status (yes/no) and mortality. Participants with ≥three vertebral fractures (HR 2.43, 95% CI 1.57-3.78), or at least one severe vertebral fracture (HR 1.65, 95% CI 1.26-2.15) had increased mortality compared to those with no vertebral fractures. DXA-based screening could be a potent and feasible tool in detecting vertebral fractures that are often clinically silent yet independently associated with premature death. Our data indicate that detailed vertebral assessment could be warranted for a more accurate survival estimation. View on Web

Development of the remote 100 ml water swallow test versus clinical assessment in patients with head and neck cancer: Do they agree?

alexandrossfakianakis shared this article with you from Inoreader Development of the remote 100 ml water swallow test versus clinical assessment in patients with head and neck cancer: Do they agree? via Head & Neck Abstract Background The 100 ml water swallow test (WST) is a validated swallow assessment used in head and neck cancer (HNC). We aimed to determine the level of agreement when completing the 100 ml WST via clinician-graded video-testing or patient self-testing compared to standard face-to-face assessment (FTF). Methods Convenience sampling from four UK centers. Inclusion criteria: patients with HNC treated with any modality prior to, or within 5 years of treatment. Participants were recruited to complete the 100 ml WST by video-testing or self-testing and compared with FTF. Results Sixty-three patients were recruited; 1 was unable to perform the task; 30 in video-testing; and 32 in self-testing. There was no difference in swallow capacity (p = 0.424) and volume (p = 0.363) for the video-testing or the self-testing swallow capacity (p = 0.777) and volume (p = 0.445). Conclusions This study demonstrates that video-testing and self-testing are reliable methods of completing the 100 ml WST for this sample of patients with HNC. View on Web

Integrated longitudinal analysis of adult grade 4 diffuse gliomas with long-term relapse interval revealed upregulation of TGF-β signaling in recurrent tumors

alexandrossfakianakis shared this article with you from Inoreader Integrated longitudinal analysis of adult grade 4 diffuse gliomas with long-term relapse interval revealed upregulation of TGF-β signaling in recurrent tumors via Neuro-Oncology Advance Access Abstract Background Adult-type diffuse gliomas, CNS WHO grade 4 are the most aggressive primary brain tumors and represent a particular challenge of therapeutic intervention. Methods In a single-center retrospective study of matched pairs of initial and post-therapeutic glioma cases with a recurrence period greater than one year, we performed whole exome sequencing combined with mRNA and microRNA expression profiling to identify processes that are altered in recurrent gliomas. Results Mutational analysis of recurrent gliomas revealed early branching evolution in seventy-five percent of patients. High plasticity was confirmed at the mRNA and miRNA levels. SBS1 signature was reduced and SBS11 was elevated, demonstrating the effect of alkylating agent therapy on the mutational landscape. There was no evidence for secondary genomic alterations driving therapy resistance. ALK7/ACVR1C and LTBP1 were upregulated, whereas LEFTY2 was downregulated, pointing towards enhanced Tumor Growth Factor β (TGF-β) signaling in recurrent gliomas. Consistently, altered microRNA expression profiles pointed towards enhanced Nuclear Factor Kappa B and Wnt signaling that, cooperatively with TGF-β, induces epithelial to mesenchymal transition (EMT), migration and stemness. TGF-β-induced expression of pro-apoptotic proteins and repression of anti-apoptotic proteins were uncoupled in the recurrent tumor. Conclusions Our results suggest an important role of TGF-β signaling in recurrent gliomas. This may have clinical implication, since TGF-β inhibitors have entered clinical phase studies and may potentially be used in combination therapy to interfere with chemoradiation resistance. Recurrent gliomas show high incidence of early branching evolution. High tumor plasticity is confirmed at the level of mic roRNA and mRNA expression profiles. View on Web

Response assessment in pediatric craniopharyngioma: recommendations from the Response Assessment in Pediatric Neuro-Oncology (RAPNO) working group

alexandrossfakianakis shared this article with you from Inoreader Response assessment in pediatric craniopharyngioma: recommendations from the Response Assessment in Pediatric Neuro-Oncology (RAPNO) working group via Neuro-Oncology Advance Access Abstract Craniopharyngioma is a histologically benign tumor of the suprasellar region for which survival is excellent but quality of life often poor secondary to functional deficits from tumor and treatment. Standard therapy consists of maximal safe resection with or without radiation therapy. Few prospective trials have been performed, and response assessment has not been standardized. The Response Assessment in Pediatric Neuro-Oncology (RAPNO) committee devised consensus guidelines to assess craniopharyngioma response prospectively. Magnetic resonance imaging (MRI) is the recommended radiologic modality for baseline and follow-up assessments. Radiologic response is defined by two-dimensional measurements of both solid and cystic tumor components. In certain clinical contexts, response of solid and cystic disease may be differentially considered based on their unique natural histories and responses to treatment. Importantly, the committee incorporated fu nctional endpoints related to neuro-endocrine and visual assessments into craniopharyngioma response definitions. In most circumstances, cystic disease should be considered progressive only if growth is associated with acute, new-onset or progressive functional impairment. Craniopharyngioma is a common pediatric CNS tumor for which standardized response parameters have not been defined. A RAPNO committee devised guidelines for craniopharyngioma assessment to uniformly define response in future prospective trials. View on Web

Hyperkalaemia and potassium binders: Retrospective observational analysis looking at the efficacy and cost effectiveness of calcium polystyrene sulfonate and sodium zirconium cyclosilicate

alexandrossfakianakis shared this article with you from Inoreader Hyperkalaemia and potassium binders: Retrospective observational analysis looking at the efficacy and cost effectiveness of calcium polystyrene sulfonate and sodium zirconium cyclosilicate via Journal of Clinical Pharmacy and Therapeutics Both CPS and SZC are equally effective at lowering acutely raised potassium concentrations with a cost analysis that favours CPS. Any claims of benefits of newer agents over established medications need to be explored in randomized trials. Abstract What is Known and Objective Hyperkalaemia is a common medical emergency in patients admitted to hospital. There is a limited evidence base supporting some of the commonly applied treatment strategies. Although, NICE has recommended the use of sodium zirconium cyclosilicate (SZC) (TA599) and patiromer (TA623) in both acute and chronic hyperkalaemia, there is a limited evidence base for their use in acute hyperkalaemia in the hospital setting, particularly when compared to the present standard of care calcium polystyrene sulfonate (CPS). Methods A retrospective review of the electronic patient record system across our hospital over a 6-month period identified 138 patients who received either SZC (65 patients) or CPS (73 patients) to manage hyperkalaemia, investigating their efficacy and cost effectiveness. Results were analysed using simple descriptive statistics. Based on the results a naïve cost comparison between the two drugs was made. Results and Discussion CPS and SZC both effectively reduced plasm potassium concentrations in patients with hyperkalaemia (6.07 and 6.03 mmol/L respectively) by 1.17 mmol/L and 1.24 mmol/L taking a similar amount of time to work (2.97 days vs. 3 days). The principle causes of hyperkalaemia identified were acute kidney injury, medication, and chronic kidney disease. Cost comparison analysis which took into account raw product price and time needed to dispense medications revealed that CPS has slightly better cost effectiveness compared to SZC albeit at a cost of increased staff input. What is New and Conclusion Both CPS and SZC were equally effective at lowering acutely raised potassium concentrations. The cost difference between the two products appears to be small. Claims regarding the benefits of newer agents over older established medications need to be properly explored in randomized trials rather than being based on small scale non-comparative studies.
