The effect of clinical interventions on the oral health‐related quality of life in older adults

alexandrossfakianakis shared this article with you from Inoreader The effect of clinical interventions on the oral health‐related quality of life in older adults via Australian Dental Journal Abstract This paper reviews the literature to assess the effectiveness of oral health interventions in influencing oral health-related quality of life (OHRQoL) in older adults. Clinical studies published in 2010 onwards reporting oral health interventions in older adults and subsequent changes in OHRQoL were systematically searched in Medline, Web of Science and EMBASE databases. Reporting followed Preferred Reporting Items for Systematic Review and Meta-Analysis criteria. Eligibility evaluation and data abstraction from eligible studies were guided by predefined PICO questions and bias assessment by the Quality in Prognosis Studies tool. The search retrieved 144 articles. Of the 20 articles that met the eligibility criteria, 45% (9) reported a statistically significant improvement in OHRQoL. The majority of studies were conducted in adults with complete edentulism (70%) and mainly focused on implant provision to support a removable prosthesis (30%). The search indicates the limited scope of current literature on geriatric dental interventions, focusing mainly on denture realignments, denture fabrication and implant placement. Although the majority of the oral health interventions focused on edentulism and removable prostheses, there are many areas of oral health interventions and their potential impact on OHRQoL in this demographic group that have yet to be explored.

Association between body composition and survival in head and neck cancer patients undergoing radiotherapy

alexandrossfakianakis shared this article with you from Inoreader Association between body composition and survival in head and neck cancer patients undergoing radiotherapy via Head & Neck Abstract Background Body composition may influence the prognosis of head and neck cancer (HNC) patients. To find out the most crucial factors in this relationship, we explored the association between body composition and survival. Methods In this prospective longitudinal study, HNC patients who underwent radiotherapy (RT) from March 2017 to December 2018 were recruited. The association between body composition and survival was analyzed using Cox proportional hazard regression. Results Final analysis included 316 patients, with a median follow-up of 34.4 months. Multivariable analysis revealed that weight loss 6 months before RT and body composition changes during RT did not affect the survival outcome. However, patients with low appendicular skeletal muscle mass index (ASMI) before RT exhibited poor overall survival (OS). ASMI before RT was an independent prognostic factor for OS. Conclusions Body composition loss was common during RT, and ASMI before RT independently influenced the survival outcomes of HNC patients. View on Web

Recurrence risk stratification and treatment strategies of patients with stage IVa‐b hypopharyngeal squamous cell carcinoma

alexandrossfakianakis shared this article with you from Inoreader Recurrence risk stratification and treatment strategies of patients with stage IVa‐b hypopharyngeal squamous cell carcinoma via Head & Neck Abstract Background Optimal treatment strategies for patients with stage IVa-b hypopharyngeal squamous cell carcinoma (HSCC) remain controversial. This study aimed to examine the high-risk factors of postoperative tumor recurrence after surgical resection of HSCC and devise individualized postoperative adjuvant treatment (POAT). Methods Overall, 218 patients with stage IVa-b HSCC who received surgery as initial treatment and with negative surgical margins were evaluated. Independent risk factors of recurrence were identified, and survival outcomes were compared according to recurrence risk and POAT use. Results POAT significantly improved recurrence-free survival (RFS) and overall survival (OS) only in the high-risk patients (p = 0.003 and 0.018, respectively). Compared with postoperative radiotherapy alone, postoperative chemoradiotherapy (pCRT) achieved significantly better RFS (p = 0.035) and OS (p = 0.048). Conclusions POATs are recommended for high-risk patients with stage Iva-b HSCC, with pCRT achieving superior outcomes. Regular re-examination after tumor resection is sufficient for low-risk patients. View on Web

Prediction of R Status in Resections for Pancreatic Cancer Using Simplified Radiological Criteria

alexandrossfakianakis shared this article with you from Inoreader Prediction of R Status in Resections for Pancreatic Cancer Using Simplified Radiological Criteria via Annals of Surgery - Most Popular Articles Objective: Predicting R status before surgery for pancreatic cancer (PDAC) patients with upfront surgery and neoadjuvant therapy. Summary Background Data: Negative surgical margins (R0) are a key predictor of long-term outcomes in PDAC. Methods: Patients undergoing pancreatic resection with curative intent for PDAC were identified. Using the CT scans from the time of diagnosis, the 2019 NCCN borderline resectability criteria were compared to novel criteria: presence of any alteration of the superior mesenteric-portal vein (SMPV) and perivascular stranding of the superior mesenteric artery (SMA). Accuracy of predicting R status was evaluated for both criteria. Patient baseline characteristics, surgical, histopathological parameters, and long-term overall survival (OS) after resection were evaluated. Results: A total of 593 patients undergoing pancreatic resections for PDAC between 2010 and 2018 were identified. Three hundred and twenty-five (54.8%) patients underwent upfront surgery, whereas 268 (45.2%) received neoadjuvant therapy. In upfront resected patients, positive SMA stranding was associated with 56% margin positive resection rates, whereas positive SMA stranding and SMPV alterations together showed a margin positive resection rate of 75%. In contrast to these criteria, the 2019 NCCN borderline criteria failed to predict margin status. In patients undergoing neoadjuvant therapy, only perivascular SMA stranding remained a predictor of margin positive resection, leading to a rate of 33% R+ resections. Perivascular SMA stranding was related to higher clinical T stage (P = 0.003) and clinical N stage (P = 0.043) as well as perineural invasion (P = 0.022). SMA stranding was associated with worse survival in both patients undergoing upfront surgery (36 vs 22 months, P = 0.002) and neoa djuvant therapy (47 vs 34 months, P = 0.050). Conclusions: The novel criteria were accurate predictors of R status in PDAC patients undergoing upfront resection. After neoadjuvant treatment, likelihood of positive resection margins is approximately halved, and only perivascular SMA stranding remained a predictive factor. View on Web

A modified dentin infection model with Fluorescent Lipopolysaccharide and LPS sampling technique to compare XP‐Endo finisher and passive ultrasonic irrigation

alexandrossfakianakis shared this article with you from Inoreader A modified dentin infection model with Fluorescent Lipopolysaccharide and LPS sampling technique to compare XP‐Endo finisher and passive ultrasonic irrigation via International Endodontic Journal Abstract Aim The LPS-dentine-infection models and sampling techniques frequently used to evaluate LPS disinfection have limitations. In this study, a lipopolysaccharides-dentine-infection (LPS-dentine-infection) model was devised using fluorescent conjugate LPS. Secondly, a sampling technique using cryogenic grinding for intraradicular LPS analysis was evaluated. Thirdly, the effectiveness of the XP-endo Finisher (XP-EF) was compared with passive ultrasonic irrigation (PUI) in removing LPS from root canal system. Methodology Sixty-nine mandibular premolars was submitted to dentine pretreatment and inoculated with fluorescent LPS conjugate (Alexa Fluor® 594). Twenty-three teeth were analysed under confocal laser scanning microscopy (CLSM) to validate this modified LPS-dentine-infection model. Forty-six teeth were randomly divided into two experimental groups: XP-EF (n = 23) and PUI (n = 23). All teeth were instrumented with XP-endo shaper (XPS; FKG Dentaire, La Chaux-de-Fonds, Switzerland) and 2.5% NaOCl. The root canals were sampled with paper points before (s1) and after (s2) instrumentation and after supplemental treatment (s3) with XP-EF and PUI. After s3, all roots were cryogenically ground for intraradicular LPS analysis (s4). Limulus amebocyte lysate (LAL) assay was used for LPS quantification. The Friedman test was used for differences in LPS among four timepoints (s1, s2, s3, and s4). Dunn's test was used for pairwise testing of timepoints. The significance level wa s set at 5% (P < .05). Results Fluorescent LPS conjugate was detected in 100% of the samples under CLSM with a penetration depth of approximately 400 μm into dentine. Chemo-mechanical preparation using XPS files significantly reduced LPS levels (p < .05). Both the XPS and PUI improved the LPS disinfection (p < .05), with no difference between them (p > .05). LPS was recovered from all samples after cryogenic grinding. The residual amount of LPS detected using the cryogenically sampling technique at s4 was approximately 3 times greater than with the paper point sampling technique at s3. Conclusion This study established a modified LPS-dentine-infection model using fluorescent conjugate LPS, and validated a LPS sampling technique for using cryopulverization intraradicular LPS analysis. Moreover, both the XP-EF and PUI further improved LPS disinfection from the root canals, and the innovative XP-EF was as effective as PUI. View on Web

No Reduction in the 226-Hz Probe Tone Acoustic Reflex Amplitude Following Severe Inner Hair Cell Loss in Chinchillas

alexandrossfakianakis shared this article with you from Inoreader No Reduction in the 226-Hz Probe Tone Acoustic Reflex Amplitude Following Severe Inner Hair Cell Loss in Chinchillas via JARO - Journal of the Association for Research in Otolaryngology via MedWorm.com AbstractThe relationship between the middle ear acoustic reflex (AR) and inner hair cell (IHC) loss is currently unknown. Given that IHC are believed to convey nearly all acoustic information to the central auditory nervous system, it has been assumed that loss of IHC would significantly impact the AR. To evaluate this relationship, we assessed the presence and amplitude of the AR in chinchillas before and after treatment with carboplatin, an anticancer drug that reliably and selectively destroys IHC in this species. Baseline measures of hearing sensitivity, including auditory brainstem response (ABR) thresholds and distortion product otoacoustic emissions (DPOAE), were assessed and then re-evaluated following carboplatin treatment. Post-carboplatin ABR thresholds and DPOAE were found to b... View on Web

Tenofovir Disoproxil Fumarate/Emtricitabine and Baricitinib for Patients at High Risk of Severe COVID-19: The PANCOVID Randomized Clinical Trial

alexandrossfakianakis shared this article with you from Inoreader Tenofovir Disoproxil Fumarate/Emtricitabine and Baricitinib for Patients at High Risk of Severe COVID-19: The PANCOVID Randomized Clinical Trial via Clinical Infectious Diseases Advance Access Abstract Background This study was designed to evaluate if patients with high risk for severe COVID-19 would benefit from treatment with TDF/FTC followed by baricitinib in case of hypoxemia and systemic inflammation. Methods PANCOVID is an open-label, double-randomized, phase 3 pragmatic clinical trial including adults with symptomatic COVID-19 with ≥ 2 comorbidities or older than 60 years conducted between 10 October 2020 and 23 September 2021. In the first randomization patients received TDF/FTC or not TDF/FTC. In the second randomization patients with room-air O2 saturation <95% and at least one increased inflammatory biomarker received baricitinib plus dexamethasone or dexamethasone alone. The primary endpoint was 28-day mortality. Main secondary endpoint was 28-day disease progression or critical care unit admission or mortality. The trial was stopped before reaching planned sample size due to the decrease in th e number of cases and a mortality rate substantially lower than expected EudraCT registration number: 2020-001156-18. Results Of the 355 included participants 97% were hospitalized at baseline. Overall, 28-day mortality was 3.1%. The 28-day mortality relative risk (RR) for participants treated with TDF/FTC was 1.76 (95% CI 0.52-5.91; p= 0.379); it was 0.42 (95% CI 0.11-1.59; p= 0.201) for those treated with baricitinib. The 28-day RR for the main secondary combined endpoint for participants treated with TDF/FTC was 0.95 (95% CI 0.66-1.40; p = 0.774); it was 0.90 (95%CI 0.61-1.33; p = 0.687) for those treated with baricitinib. Conclusions Our results do not suggest a beneficial effect of TDF/FTC; nevertheless, they are compatible with the beneficial effect of baricitinib already established by other clinical trials.
