Prevention of the Occupational Silicosis Epidemic

alexandrossfakianakis shared this article with you from Inoreader Prevention of the Occupational Silicosis Epidemic in Australia: What Do Those Who Assess Workplace Health Risk Think Should Be Done Now? via Annals of Work Exposures and Health Advance Access Abstract An Australian National Dust Disease Taskforce was established to address the re-emergence of occupational lung disease, in particular silicosis. Exposure to respirable crystalline silica (RCS) occurs in various industries in Australia. We asked occupational hygienists about their practical experiences and perspectives on RCS exposure and regulatory action. A total of 105 members of the Australian Institute of Occupational Hygienists completed an anonymous questionnaire, which addressed individual characteristics, experience, perceived level of employer awareness, effectiveness of current regulation, and recommendations for improvement, across three main industrial sectors. Based on professional experience, 71% were concerned about the potential for RCS over-exposure. Barriers to adequate exposure control included lack of management commitment and financial resources. The employment of specialist occupational hygiene inspectors was considered to b e the most effective regulatory strategy. Given the large number of exposed workers in the construction industry, with only a moderate awareness, there is the potential for significant cost shifting of the burden of occupational lung disease from employers on to individuals and the public health system. A nationally consistent approach to RCS exposure control across all industrial sectors is now recommended, with an increased focus on measuring and controlling exposure. View on Web

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

Effectiveness of root canal treatment for vital pulps compared with necrotic pulps in the presence or absence of signs of periradicular pathosis: a systematic review and meta‐analysis

alexandrossfakianakis shared this article with you from Inoreader Effectiveness of root canal treatment for vital pulps compared with necrotic pulps in the presence or absence of signs of periradicular pathosis: a systematic review and meta‐analysis via International Endodontic Journal Abstract Background Pre-operative pulpal status may influence the outcomes of root canal treatment (RCTx) according to various measures used. Objectives To compare effectiveness of RCTx of teeth with a vital pulp versus a necrotic pulp using a range of clinical and patient-related outcomes, for the development of S3-Level clinical practice guidelines. Methods A search was conducted in the PubMed-MEDLINE, Scopus, EMBASE, Google scholar databases and available repositories, followed by hand searches, until 29 March 2022. Clinical studies published in English language comparing the stipulated outcomes of RCTx of teeth with vital versus necrotic pulp were included. The Newcastle-Ottawa Scale was adapted to assess study quality. Effects of pulpal status were estimated and expressed as risk ratio (RR) using fixed- and random-effect meta-analyses. The quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation tool. Results Twenty-eight studies published between 1961 and 2021 were included. Five studies have investigated the 'tooth survival' outcome, four reported pulpal status was not a significant predictor, consistent with meta-analysis finding (RR: 1.00; 95% CI: 1.00, 1.00; n=3). Seven studies reported pulpal status had no significant influence on post-operative pain, regardless of duration after treatment. Sixteen studies have analysed 'periapical health', eleven revealed pulpal status had no significant influence. Meta-analyses revealed the influence was not significant if pre-operative periapical radiolucency was absent (RR: 0.95; 95% CI: 0.90, 1.00; n=9) but significant if it was present (RR: 1.12; 95% CI: 1.05, 1.19; n=11). Most studies were classified as 'some concerns' (n=16) to 'low' (n=10) risk of bias (RoB). Discussion Evidence is limited and only available for three outcomes when comparing the effectiveness of RCTx in permanent teeth with vital pulp versus pulp necrosis. Nevertheless, the quality of available evidence was moderate to high. The 'periapical health' data heterogeneity could be explained by pre-operative radiolucency, thus RCTx was found more effective for prevention than resolution of apical periodontitis. Conclusions There was no significant difference in the 'tooth survival', 'post-operative pain' and 'evidence of apical radiolucency' outcomes of RCTx in teeth with vital or necrotic pulps.

Systemic conditions associated with increased risk to develop oral squamous cell carcinoma: Systematic review and meta‐analysis

alexandrossfakianakis shared this article with you from Inoreader Systemic conditions associated with increased risk to develop oral squamous cell carcinoma: Systematic review and meta‐analysis via Head & Neck Abstract This study aimed to map systemic alterations predisposing to oral squamous cell carcinoma (OSCC) onset. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Five databases were used to access (1) reports of OSCC co-occurring in patients with systemic conditions, (2) prevalence of OSCC among these patients, and (3) clinicopathological profiles. Data from more than 1 million patients worldwide showed that Fanconi's anemia, xeroderma pigmentosum, dyskeratosis congenital, chronic fatigue syndrome, and patients post bone marrow transplantation (BMT) present increased risk for OSCC development. The overall prevalence of OSCC in syndromic patients and post-BMT were 0.65% (95% CI = 0.13–3.11, p < 0.01) and 5.83% (95% CI = 0.00–30.90, p < 0.01), respectively. The certainty of the evidence was moderate. This study demonstrated that some systemic conditions predispose to OSCC. These results present an impact on the screening of OSCC in systemically compromised patients. 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

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.
