Objectives: Frailty is a relevant issue in older people, being associated with several negative outcomes. Increasing literature is reporting that pollution (particularly air pollution) can increase the risk of frailty, but the research is still limited. We aimed to investigate the potential association of pollution (air, noise) with frailty and prefrailty among participants 60 years and older of the UK Biobank study., Design: Cross-sectional., Settings and Participants: Older participants (age ≥ 60 years) participating to the UK Biobank., Methods: Frailty and prefrailty presence were ascertained using a model including 5 indicators (weakness, slowness, weight loss, low physical activity, and exhaustion). Air pollution was measured through residential exposures to nitrogen oxides (NO x ) and particulate matter (PM 2.5 , PM 2.5-10 , PM 10 ). The average residential sound level during the daytime, the evening, and night was used as an index for noise pollution., Results: A total of 220,079 subjects, aged 60 years and older, was included. The partial proportional odds model, adjusted for several confounders, showed that the increment in the exposure to NO x was associated with a higher probability of being in both the prefrail and frail category [odds ratio (OR) 1.003; 95% CI 1.001-1.004]. Similarly, the increase in the exposure to PM 2.5-10 was associated with a higher probability of being prefrail and frail (OR 1.014; 95% CI 1.001-1.036), such as the increment in the exposure to PM 2.5 that was associated with a higher probability of being frail (OR 1.018; 95% CI 1.001-1.037)., Conclusions and Implications: Our study indicates that the exposure to air pollutants as PM 2.5 , PM 2.5-10 , or NO x might be associated with frailty and prefrailty, suggesting that air pollution can contribute to frailty and indicating that the frailty prevention and intervention strategies should take into account the dangerous impact of air pollutants., (Copyright © 2023 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Objective: The aim of this study was to retrospectively analyze the outcome of LR-3 and LR-4 without arterial phase hyperenhancement (APHE), and identify which features could predict LR-5 progression on serial Gd-EOB-DTPA-enhanced MRI follow-up., Methods: Forty-nine cirrhotic patients with 55 LR-3 and 19 LR-4 without APHE were evaluated. Observations were classified as decreased, stable or increased in category at follow-up. Observation size and LI-RADS major and ancillary features were evaluated., Results: Seventeen/fifty-five (31%) LR-3 and 8/19 (42%) LR-4 progressed to LR-5 at follow-up. Baseline LI-RADS major and ancillary features were not significantly different among LR-3 and LR-4. A diameter ≥ 10 mm significantly increased LR-5 progression risk of LR-3 (OR = 6.07; 95% CI: 0.12; 60.28]; P < .001). LR-4 with a diameter ≥ 10 mm more likely become LR-5 at follow-up (OR = 8.95; 95% CI: 0.73; 111.8; P = .083])., Conclusion: LR-3 and LR-4 without APHE were often downgraded or remained stable in category on Gd-EOB-DTPA-enhanced MRI follow-up., (Copyright © 2020 Elsevier Inc.

Objectives: To investigate whether assessment with two geriatric screening tools shows a correlation with clinical outcomes of patients aged 65 years or more, with early-stage Non-Small Cell Lung Cancer (es-NSCLC) treated with hypofractionated stereotactic radiotherapy., Methods: From March 2014 to June 2018 we retrospectively evaluated 42 patients with stage I and II lung tumors. Patients were assessed with Charlson Comorbidity Index (CCI) and G8 screening tool. Median age was 74 years (range, 65-91). Stereotactic radiotherapy was performed with Helical Tomotherapy delivering 50-70 Gray (Gy) in 8-10 fractions. Toxicity was evaluated using Common Terminology Criteria for Adverse Events v4.0 criteria., Results: Median CCI and G8 scores were 6 (4-11) and 14 (12-17), respectively. With a median follow-up of 14 months (3-37), we observed: 3 cases of acute Grade 2 (G2) radiation pneumonitis, 1 late G2 non-cardiac chest pain, 1 late G2 dysphagia and 1 case of late G2 radiation pneumonitis. At statistical analysis, G8 scores ≤14 were significantly associated with late toxicity rates (p = .0073). Local failure was predictive of disease free survival and Overall Survival (p < .001 and p = .001). Death occurred in 12 patients, 6 for non-cancer related causes, with 1- and 2-yrs cancer specific survival rates of 94.8% and 90%, 1- and 2-yrs OS rates of 93% and 80%, respectively., Conclusions: Our experience shows a correlation between G8 scores and late toxicity in older patients treated with stereotactic radiotherapy for lung cancer, suggesting the need for prospective studies evaluating its use for the identification of patients at higher risk of adverse events., (Copyright © 2019 Elsevier Inc.

Background: HR HPV infection was proposed as aetiological factor of oral squamous cell carcinomas (OSCC). HPV frequency in OSCC is highly variable, due to the discrepancy in oral sampling procedures, HPV testing methods and inclusion criteria regarding tumour site (strictly oral cavity vs. nearby structures). Our aim was to compare HPV DNA frequency and type-specific distribution in paired cytological and histological samples of SCC strictly located in oral cavity. The correlation between HPV detection rate by each method of sampling and demographical, behavioural and clinical-pathological variables was also examined., Patients and Methods: HPV DNA was detected in brushed cells and formalin-fixed paraffin-embedded biopsies obtained from 83 consecutive unselected immunocompetent adults with OSCC. HPV DNA detection was performed in all samples by nPCR followed by direct DNA sequencing and the assay INNO-LiPA HPV Genotyping. Univariate and multivariate statistics were used, including Cohen κ index to evaluate agreement between two methods and association between HPV infection and demographical, behavioural and clinical-pathological variables for each method of sampling (p<0.05 statistically significant)., Results: HPV DNA was detected in 15.7% (13/83) of brushings and 12.1% (10/83) of biopsies (p>0.05). High risk HPV 51, 16 and 39 were genotypes more frequently detected, especially among biopsies; no concordance between two methods was found (Cohen κ index=0.04, p=0.34)., Conclusion: A fraction of OSCC could be linked to HR HPV infection in the Mediterranean area. Although without a statistical significance, biopsy specimen demonstrated more accurate for HR HPV detection than brushing in OSCC., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Objective: A previous sham-controlled multinational study demonstrated the short-term efficacy and safety for xerostomia treatment of an intraoral device that delivers electrostimulation to the lingual nerve. The objective of this study was to test the hypothesis that those beneficial effects would be sustained over an 11-month period., Study Design: The device was tested on a mixed sample of 94 patients with xerostomia in an open-label, uncontrolled, prospective multicenter trial. Statutory outcome assessments were done at 5th, 8th, and 11th months and analyzed by multiple comparisons., Results: Improvements achieved at month 5 from baseline were sustained throughout the follow-up period for the primary outcome, xerostomia severity, and the secondary outcomes resting whole salivary flow rate, xerostomia frequency, oral discomfort, and difficulties in speech, swallowing, and sleeping. No significant side effects were detected., Conclusions: The beneficial effects of a removable intraoral electrostimulating device were sustained for an 11-month period., (Copyright © 2012 Elsevier Inc.

A key issue in oral HPV infection is whether it can be associated with a genital HPV infection, or whether it can be considered as an independent event. This analysis evaluated the frequency and type-concordance of oral HPV infection in women with cervical HPV infection by means of: (i) a cross-sectional study on a sample (n=98) of Italian women; and (ii) a literature-based metanalysis, including the experimental study the subject of this Paper and nine other published studies (n=1017), which also examined the influence of oral sampling procedure (oral brushing vs oral rinse) and HIV status on oral HPV detection. The prevalence of oral HPV infection in the Italian study was 14.3% (95% CI: 7.4-21.2); the prevalence of type-concordance was 21.4% (95% CI: 0.0-43.6) and it was only marginally significant (P=0.05). The prevalence of oral HPV infection in the metanalysis was estimated as 18.1% (95% CI: 10.3-25.9); the prevalence of type-concordance was 27.0% (95% CI: 12.3-41.7), and it was statistically significant (P=0.002). The metanalysis also showed that the oral sampling procedure was not a determinant of HPV detection; however, HIV status increased the likelihood of oral HPV infection (HIV-positive vs negative: 27.2%; 95% CI: 22.1-32.2 vs 15.5%; 95% CI: 6.9-24.2) and type-concordance (HIV-positive vs negative: 46.8%; 95% CI: 34.7-58.9 vs 15.6%; 95% CI: 0.8-30.4). Oral HPV infection and type-concordance in women with cervical HPV infection are more prevalent than could be expected by chance; this finding is consistent with the notion of a degree of dependence of the oral site on the cervical site. Furthermore, oral HPV prevalence and type-concordance are influenced by immunity., (Copyright © 2011 Elsevier Ltd. All rights reserved.)

Introduction: In the literature, there exists a wide range of human papillomavirus (HPV) DNA prevalence for head and neck squamous cell carcinoma (HNSCC), especially in relation to methods of viral detection and the lesion site. We estimated the pooled prevalence of HPV DNA in biopsies of HNSCC generically grouped versus oral squamous cell carcinoma (OSCC) in relation to the method of viral DNA detection, with the primary end point of verifying if these two variables (specification of tumour site and method of HPV DNA identification) influence the datum on HPV assay., Methods: By means of MEDLINE/PubMED/Ovid databases, we selected studies examining paraffin-embedded (PE) biopsies of HNSCC and OSCC. According to the inclusion criteria, 62 studies were analyzed. The following data were abstracted: sample size, HPV DNA prevalence, methods of detection [PCR and in situ hybridization (ISH)] and HPV genotypes. After testing the heterogeneity of the studies by the Cochran Q test, metanalysis was performed using the random effects model., Results: The pooled prevalence of HPV DNA in the overall samples (Sigma: 4852) was 34.5%, in OSCC it was 38.1% and in the not site-specific HNSCC was 24.1%. With regard to the detection method, PCR-based studies reported a higher prevalence rate than ISH-based rates (34.8, versus 32.9%) especially in the OSCC subgroup (OSCC PCR based: 39.9%)., Conclusion: These findings support the assumption that a correct distinction of HNSCC by site, together with the use of more sensitive HPV DNA detection methods, should be considered as essential prerogatives in designing future investigations into viral prevalence in head and neck tumors.

We aimed to evaluate if in oral squamous cell carcinoma (OSCC) there is a relationship between histological grading (HG), TNM clinical stage and HPV infection; and to study the performance of fuzzy logic compared to traditional statistics, in the analysis of HPV status and correlates of OSCC. In cross-sectional analysis, the study group comprised 63 patients (mean age 68.89 years (SD +/-11.78), range (32-93); males 28 (44.4%), females 35 (55.6%)) with OSCC histologically diagnosed. HPV-DNA was studied in exfoliated oral epithelial cells by nested PCR (MY09/MY11 and GP5+/GP6+ primers). Data were analysed in parallel by traditional statistics with multivariate analysis and a fuzzy logic (FL) technique (membership functions as input, the ANFIS methodology, and the Sugeno's model of first order). HPV infection was detected in 24/63 (38.1%) of OSCC, as being HPV+ve 14/36 (38.9%) in G1, 7/18 (38.9%) in G2, and 3/9 (33.3%) in G3; HPV+ve 8/33 (24.2%) in Stage I, 9/12 (75.0%) in Stage II, 6/11(54.5%) in Stage III, and 1/7 (14.3%) in Stage IV. In both methods of analysis, no significantly increased risk of HPV infection was found for any HG score; whereas, TNM stage II was significantly associated to HPV infection (p=0.004; OR=9.375 (95% CI=2.030:43.30); OR'=11.148 (95% CI=1.951:43.30)), and, in particular, to primary tumour size T2 (p=0.0036; OR=7.812 (95% CI=1.914:31.890); OR'=9.414 (95% CI=1.846:48.013)); FL (% of prevision: 79.8; Root Mean-Square Error (RMSE): 0.29). No association was found between HPV infection and any demographical variable. Our findings show an association between HPV infection with TNM (stage II-T2), but not with histological grading of OSCC. Also, FL seems to be an additional effective tool in analysing the relationship of HPV infection with correlates of OSCC.
