An Independent Seizure-Onset Zone in Medial Temporal Lobe Found by 18F-FDG PET Imaging Besides Epileptogenic Periventricular Nodular Heterotopia

alexandrossfakianakis shared this article with you from Inoreader An Independent Seizure-Onset Zone in Medial Temporal Lobe Found by 18F-FDG PET Imaging Besides Epileptogenic Periventricular Nodular Heterotopia via Clinical Nuclear Medicine - Published Ahead-of-Print A 23-year-old man with drug-resistant epilepsy was admitted for presurgical evaluation. The epileptogenic zone could not be derived from seizure semiology and scalp electroencephalographic monitoring definitely. MRI showed periventricular nodular heterotopia in occipital horn of left lateral ventricle with high FDG uptake on interictal 18F-FDG PET scan, whereas the hypometabolic zone in the left medial temporal lobe was also found on PET with no abnormality on MRI. Stereoelectroencephalographic implantation was performed to identify the seizure-onset zone. Two independent epileptogenic foci located in periventricular nodula r heterotopia and left hippocampus were validated by stereoelectroencephalographic monitoring and the outcome of subsequent thermocoagulation.

Combined 18F-FDG PET/CT Radiomics and Sarcopenia Score in Predicting Relapse-Free Survival and Overall Survival in Patients With Esophagogastric Cancer

alexandrossfakianakis shared this article with you from Inoreader Combined 18F-FDG PET/CT Radiomics and Sarcopenia Score in Predicting Relapse-Free Survival and Overall Survival in Patients With Esophagogastric Cancer via Clinical Nuclear Medicine - Published Ahead-of-Print Purpose The aim of this study was to determine if radiomic features combined with sarcopenia measurements on pretreatment 18F-FDG PET/CT can improve outcome prediction in surgically treated adenocarcinoma esophagogastric cancer patients. Patients and Methods One hundred forty-five esophageal adenocarcinoma patients with curative therapeutic intent and available pretreatment 18F-FDG PET/CT were included. Textural features from PET and CT images were evaluated using LIFEx software (lifexsoft.org). Sarcopenia measurements were done by measuring the Skeletal Muscle Index at L3 level on the CT component. Univariable and multivariable analyses were conducted to create a model including the radiomic parameters, clinical features, and Skeletal Muscle Index score to predict patients' outcome. Results In multivariable analysis, we combined clinicopathological parameters including ECOG, surgical T, and N staging along with imaging derived sarcopenia measurements and radiomic features to build a predictor model for relapse-free survival and overall survival. Overall, adding sarcopenic status to the model with clinical features only (likelihood ratio test P = 0.03) and CT feature (P = 0.0037) improved the model fit for overall survival. Similarly, adding sarcopenic status (P = 0.051), CT feature (P = 0.042), and PET feature (P = 0.011) improved the model fit for relapse-free survival. Conclusions PET and CT radiomics derived from combined PET/CT integrated with clinicopathological parameters and sarcopenia measurement might improve outcome prediction in patients with nonmetastatic esophagogastric adenocarcinoma.

Melanin-Targeted PET Imaging Sheds Light on Pigment Epithelioma in Corpus Ciliare

alexandrossfakianakis shared this article with you from Inoreader Melanin-Targeted PET Imaging Sheds Light on Pigment Epithelioma in Corpus Ciliare via Clinical Nuclear Medicine - Published Ahead-of-Print A 57-year-old woman had gradually decreased visual acuity in the left eye, accompanied by distension and pain. MRI demonstrated a small neoplasm in corpus ciliare, which promoted PET imaging for further assessment. 18F-FDG PET imaging found no obvious uptake in the lesion. However, melanin-targeted PET imaging demonstrated the lesion with avid 18F-PFPN (18F-N-(2-diethylaminoethyl)-4-(2-[2-ethoxy]-ethoxy)pyridine) accumulation (SUVmax, 7.1), which suggested it with melanin expression. Pigmented epithelial adenoma was further confirmed by pathology. Our case illustrated that pigmented epithelial adenoma is characterized by av id 18F-PFPN accumulations and can be detected even in a hidden location with a size of ≤5 mm. View on Web

Adherence Of Candida Albicans to Five Long‐Term Silicone‐Based Denture Lining Materials Bonded to CAD‐CAM Denture Base

alexandrossfakianakis shared this article with you from Inoreader Adherence Of Candida Albicans to Five Long‐Term Silicone‐Based Denture Lining Materials Bonded to CAD‐CAM Denture Base via Journal of Prosthodontics Abstract Purpose : Knowledge about quantifying the number as well as the retention and adhesion of Candida albicans blastoconidia to silicone denture liners is limited. Thus, the aim of this in vitro study was to explore the adherence of Candida albicans to the surface of five long-term silicone-based soft denture lining materials, using artificial saliva. Materials & Methods A total of 50 specimens (10 × 10 × 3 mm) of five long-term resilient liners (Molloplast-B; GC Reline Soft; Elite Soft Relining; Tokuyama Sofreliner S; Ufigel SC), bonded to a computer-aided design and computer-aided manufacturing denture base, were prepared. The specimens were inoculated and incubated in artificial saliva for 1h and 24h with a standardized (2.8 × 106 cfu/ml) Candida albicans suspension. At the end of the incubation period, the specimens were stained with acridine orange and observed, using fluorescence microscopy. Results : After 1h and in 24h, Molloplast B demonstrated significantly earlier adherence of Candida albicans cells compared to the other chairside materials (p<0.001 and p<0.001, respectively), where the mean number of cells also increased in the frontal parts. Regarding the rate of Candida albicans proliferation from 1h to 24 hours within the materials, there was an increase in all materials (Molloplast B: p<0.001; GC Reline Soft: p = 0.220; Elite Soft Relining: p = 0.032; Tokuyama Sofreliner S: p = 0.001; Ufigel Sc: p = 0.001). The Ufigel Sc showed a significant 2.5-fold increase at 24h. Conclusions : Long-term silicone denture liners accumulate a significant amount of Candida albicans blastoconidia and their coverage by them increases progressively over time.

Flexural Strength of Various Provisional Restorative Materials for Rehabilitation After Aging

alexandrossfakianakis shared this article with you from Inoreader Flexural Strength of Various Provisional Restorative Materials for Rehabilitation After Aging via Journal of Prosthodontics Abstract Purpose Durability of provisional restoration is crucial for full-mouth reconstruction, which may be influenced by aging. This study evaluated the effect of aging on the flexural strength of provisional materials for oral rehabilitation. Materials and Methods Bar specimens (2×2×25 mm) were fabricated from CAD-CAM [Vita CAD-Temp® (VC), Telio®CAD (TC), artBloc® (RC)], auto polymerized- [Protemp™IV (PA), Luxatemp® (LA), Unifast™Trad (UA)]. Results TCNG indicated the highest mean of σ (133.49 ±4.32), whereas VCNG indicated the lowest mean of σ (84.62 ±3.73) for non-aging. Upon aging process, TCAG revealed the highest mean of σ (123.11 ±4.55), while VCAG possessed the lowest mean of σ (84.05 ±6.39). Significant differences among various provisional materials were indicated (p = 0.001). Aging significantly affected flexural strength (p = 0.001). Conclusions The CAD-CAM provisional material possessed higher flexural strength than heat-polymerized PMMA and auto-polymerized PMMA, which was suggested as a provisional material for rehabilitation. Aging reduced strength for all materials tested. This article is protected by copyright. All rights reserved View on Web

Development and validation of the Fat Attitudes Assessment Toolkit (FAAT): A multidimensional nonstigmatizing measure of contemporary attitudes toward fatness and fat people

alexandrossfakianakis shared this article with you from Inoreader Development and validation of the Fat Attitudes Assessment Toolkit (FAAT): A multidimensional nonstigmatizing measure of contemporary attitudes toward fatness and fat people via Journal of Applied Social Psychology Abstract Many instruments recommended for measuring attitudes toward fatness and "obesity" were developed in the 1990s, a time when the "obesity epidemic" was gaining momentum and anti-fat rhetoric was normative. Consequently, these instruments have tended to focus on assessing negative appraisals of fatness and fat people and reinforce weight stigma. As fat discourse has matured and expanded to incorporate fat positive attitudes, a nonstigmatizing way of measuring contemporary fat attitudes and beliefs in quantitative research is required. To address this need, we developed the Fat Attitudes Assessment Toolkit (FAAT). In this article, we describe the development of the FAAT and provide initial evidence for the scale's validity and psychometric properties across three studies. Study 1 included a systematic process for developing the extensive item pool that was reviewed by subject matter experts and a community panel. We explored and identified an initial multidimensional structure for the FAAT. Study 2 expanded and confirmed the factor structure with additional analyses in an independent sample and provided evidence for the overall reliability of the subscale scores and reliability as a function of gender and identification as fat. Construct and criterion validity of the subscale scores were also demonstrated. Study 3 provided evidence for the test-retest reliability of the FAAT subscales scores over time. The FAAT includes nine robust scales: Empathy, Activism Orientation, Size Acceptance, Attractiveness, Critical Health, General Complexity, Socioeconomic Complexity, Responsibility, and Body Acceptance. Specific subscales can be combined to form two composite measures: Fat Acceptance and Attribution Complexity. The scales that comprise the FAAT measure specific elements of attitudes towards fat people that are frequently targeted in weight stigma reduction research and activism; the FAAT thus offers a powerful and precise method for evaluating weight stigma reduction interventions that allows for an assessment of shifts toward more positive attitudes.

Regeneration of keratinized tissue around teeth and implants following coronal repositioning of alveolar mucosa with and without a connective tissue graft. An experimental study in dogs

alexandrossfakianakis shared this article with you from Inoreader Regeneration of keratinized tissue around teeth and implants following coronal repositioning of alveolar mucosa with and without a connective tissue graft. An experimental study in dogs via Journal of Clinical Periodontology Abstract Aim To compare clinical and histological keratinized tissue formation around teeth and implants following coronal repositioning of alveolar mucosa with or without a connective tissue graft. Methods In 9 beagle dogs, the third and fourth premolars (P3, P4) were extracted from one side of the maxilla. Three months after the tooth extraction, a full-thickness buccal flap was raised and 2 implants were placed in those healed areas. On the contralateral side, a buccal flap was also raised at the P3, P4 area. Before suturing, the dogs were randomly assigned to 3 study groups (control, non-keratinized tissue [NKT], and non-keratinized tissue connective tissue graft [NKT-CTG]). In the control group, the buccal flaps were repositioned around the teeth (P3, P4) on one side, and implants on the other side, presenting an adequate band of keratinized tissue (KT). For the NKT and NKT-CTG groups, this buccal KT was then excised. In the NKT group, the buccal flap without KT (alveolar mucosa) was repositioned around the teeth and implants. In the NKT-CTG group, a connective tissue graft taken from the excised KT was sutured to the buccal alveolar mucosa and then both were repositioned around the teeth and implants. The clinical height of the KT was measured at baseline and at 1, 2, and 3 months of healing. The animals were sacrificed at 3 months, at which point the KT height was measured histologically. Results The control group presented normal healing with a band of KT surrounding the teeth and implants. In the NKT and NKT-CTG groups, a new KT band approximately 2 mm in height (measured clinically and histologically) spontaneously formed around all teeth, regardless of whether a connective tissue graft had been placed. In the NKT implant group, no new KT was observed (clinically or histologically). Around the implants in the NKT-CTG group, a small amount of KT was formed in just 2 of the 6 implants. Conclusion After surgical excision of KT, spontaneous KT is formed around teeth but not around implants, regardless of the placement of a connective tissue graft.

SARS-CoV-2 incidence and risk factors in a national, community-based prospective cohort of U.S. adults

alexandrossfakianakis shared this article with you from Inoreader SARS-CoV-2 incidence and risk factors in a national, community-based prospective cohort of U.S. adults via Clinical Infectious Diseases Advance Access Abstract Background Prospective cohort studies of SARS-CoV-2 incidence complement case-based surveillance and cross-sectional seroprevalence surveys. Methods We estimated the incidence of SARS-CoV-2 infection in a national cohort of 6,738 U.S. adults, enrolled March-August 2020. Using Poisson models, we examined the association of social distancing and a composite epidemiologic risk score with seroconversion. The risk score was created using LASSO regression to identify factors predictive of seroconversion. The selected factors were household crowding, confirmed case in household, indoor dining, gathering with groups ≥ 10, and no masking in gyms/salons. Results Among 4,510 individuals with ≥1 serologic test, 323 (7.3%, 95% confidence interval [CI] 6.5%-8.1%) seroconverted by January 2021. Among 3,422 participants seronegative in May-September 2020 and retested during November 2020-January 2021, 161 seroconverted over 1,646 person-years of follow-up (9.8 per 100 person-years [95%CI 8.3-11.5]). Seroincidence rate was lower among females compared to males (IRR: 0.69, 95% CI 0.50-0.94) and higher among Hispanic (IRR: 2.09, 95% CI 1.41-3.05) participants compared to White non-Hispanic. In adjusted models, participants who reported social distancing with people they did not know (IRRalways vs. never: 0.42, 95% CI 0.20-1.0) and with people they knew (IRRalways vs. never 0.64, 95%CI 0.39-1.06; IRRsometimes vs. never 0.60, 95% CI 0.38-0.96) had lower seroconversion risk. Seroconversion risk increased with epidemiologic risk score (IRRmedium vs. low 1.68, 95% CI 1.03-2.81; IRRhigh vs. low 3.49, 95% CI 2.26-5.58). Only 29% of those who seroconverted reported isolating and 19% were asked about contacts. Conclusion Modifiable risk factors and poor reach of public health strategies drove SARS-CoV-2 transmission across the U.S. View on Web
