Metabolic-related outcomes after switching from tenofovir disoproxil fumarate to tenofovir alafenamide in adults with HIV: a multicenter prospective cohort study.

alexandrossfakianakis shared this article with you from Inoreader Metabolic-related outcomes after switching from tenofovir disoproxil fumarate to tenofovir alafenamide in adults with HIV: a multicenter prospective cohort study. via Clinical Infectious Diseases Advance Access Abstract Background Tenofovir alafenamide (TAF) has replaced tenofovir disoproxil fumarate (TDF) in many clinical settings. However, concerns remain about potential metabolic complications of TAF. We aimed to evaluate changes in weight, laboratory markers, and metabolic-related clinical events after replacing TDF with TAF. Methods Multicenter prospective cohort study in the Spanish CoRIS cohort. We included virologically suppressed adults with HIV receiving TDF for more than 12 months who either switched to TAF or maintained TDF, with no changes in the core agent. Participants were matched by propensity score. We fitted generalized equation models to assess changes in weight, blood lipids, and hepatic steatosis index, and to compare the incidence of diabetes, hypertension, and lipid-lowering drug use after 144 weeks. Results 1,446 participants were matched in each group. Median age was 38 years, 85% were male, mean weight at ba seline was 73 kilograms. Participants who switched to TAF had a mean weight increase of +0.5 kg at 144 weeks over those who maintained TDF, with no difference in the occurrence of overweight or obesity. Individuals who switched to TAF had a significant increase in total cholesterol (+7.9 mg/dL) and triglycerides (+11.2 mg/dL), with no differences in the total cholesterol-HDL ratio. However, no increased incidence of diabetes, hypertension, or lipid-lowering drug use was observed after the follow-up period. Conclusions Switching from TDF to TAF is associated with modest weight gain and increases in total cholesterol and triglycerides, without an impact on the incidence of obesity or metabolic-related clinical events, in this Spanish cohort with a majority white male population.

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.

Cytocompatibility and bioactive potential of AH Plus Bioceramic Sealer: an in vitro study

alexandrossfakianakis shared this article with you from Inoreader Cytocompatibility and bioactive potential of AH Plus Bioceramic Sealer: an in vitro study via International Endodontic Journal Abstract Abstract Aim To assess the cytocompatibility and bioactive potential of the new calcium silicate cement-based sealer AH Plus Bioceramic Sealer (AHPbcs) on human periodontal ligament stem cells (hPDLSCs) compared to the epoxy resin-based sealer AH Plus (AHP) and the calcium silicate cement-based sealer Endosequence BC Sealer (ESbcs). Methodology Standardized sample discs and 1:1, 1:2, and 1:4 eluates of the tested materials were prepared. The following assays were performed: surface element distribution via SEM-EDX, cell attachment and morphology via SEM, cell viability via a MTT assay, cell migration/proliferation via a wound-healing assay, osteo/cemento/odontogenic marker expression via RT-qPCR, and cell mineralized nodule formation via Alizarin Red S staining. HPDLSCs were isolated from extracted third molars. Comparisons were made with hPDLSCs cultured in unconditioned (negative control) or osteogenic (positive control) culture media. Statistical significance was established at p<0.05. Results A higher peak of Ca2+ was detected from ESbcs compared with AHPbcs and AHP in SEM-EDX. Both AHPbcs and ESbcs showed significantly positive results in the cytocompatibility assays (cell viability, migration/proliferation, attachment, and morphology) compared with a negative control group, while AHP showed significant negative results. Both AHPbcs and ESbcs exhibited an upregulation of at least one osteo/odonto/cementogenic marker compared to the negative and positive control groups. Both ESbcs and AHPbcs showed a significantly higher calcified nodule formation than the negative and positive control groups, indicative of their biomineralization potential, and were also significantly higher than AHP group. Conclusion AH Plus Bioceramic Sealer exhibited a significantly higher cytocompatibility and bioactive potential than AH Plus, and a similar cytocompatibility to that of Endosequence BC Sealer. Endosequence BC Sealer exhibited a significantly higher mineralization potential than the other tested sealers. The results from this in vitro study act as supporting evidence for the use of AH Plus bioceramic sealer in root canal treatment. View on Web

Newborn body composition and child cardiovascular risk markers: a prospective multi-ethnic Asian cohort study

alexandrossfakianakis shared this article with you from Inoreader Newborn body composition and child cardiovascular risk markers: a prospective multi-ethnic Asian cohort study via International Journal of Epidemiology - Advance Access Abstract Background Early epidemiological studies have associated low birthweight with increased cardiovascular risk. We aimed to examine whether the fat and fat-free components of birthweight have differing relationships with childhood cardiovascular risk markers. Methods In the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort, air displacement plethysmography was conducted within 24 h after delivery in 290 naturally conceived singletons. We investigated associations of newborn cohort-specific standardized z-score of fat mass, fat-free mass, body fat percentage and birthweight on child (at 6 years of age) carotid intima-media thickness, pulse wave velocity, blood pressure, prehypertension/hypertension (>110/70 mmHg) and standardized systolic and diastolic blood pressure (SBP and DBP) trajectories (at 3–6 years of age), taking account of maternal education, height, tobacco exposure, parity, ethnicity, child� �s sex, gestational age, age at follow-up, and other maternal factors. Results Clear inverse associations were seen for blood pressure with z-score of fat mass [SBP, β (95% CI): −1.31 mmHg (−2.57, −0.06); DBP: −0.79 mmHg (−1.74, 0.15)] and body fat percentage [SBP: −1.46 mmHg (−2.73, −0.19); DBP: −0.80 mmHg (−1.75, 0.16)], but not with fat-free mass [SBP: 0.27 mmHg (−1.29, 1.83)]; DBP: −0.14 mmHg (−1.30, 1.03)]. Being in the lowest tertile of fat mass or body fat percentage was associated with higher blood pressure trajectories and prehypertension/hypertension risk [OR (95% CI), fat mass: 4.23 (1.41, 12.68); body fat percentage: 3.22 (1.09, 9.53)] without concomitantly higher overweight/obesity risk. Conclusions At birth, low adiposity was associated with increased childhood blood pressure. Low newborn adiposity might serve as a marker of poor fetal growth or suboptimal intrauterine conditions associated with hypertension risk later in life. View on Web

Eano-Euracan-Sno Guidelines on Circumscribed Astrocytic GLIOMAS, Glioneuronal and Neuronaltumors

alexandrossfakianakis shared this article with you from Inoreader Eano-Euracan-Sno Guidelines on Circumscribed Astrocytic GLIOMAS, Glioneuronal and Neuronaltumors via Neuro-Oncology Advance Access Abstract In the new WHO 2021 Classification of CNS Tumors the chapter "Circumscribed astrocytic gliomas, glioneuronal and neuronal tumors" encompasses several different rare tumor entities, which occur more frequently in children, adolescents and young adults. The Task Force has reviewed the evidence of diagnostic and therapeutic interventions, which is low particularly for adult patients, and draw recommendations accordingly. Tumor diagnosis, based on WHO 2021, is primarily performed using conventional histological techniques; however, molecular workup is important for differential diagnosis, in particular DNA methylation profiling for the definitive classification of histologically unresolved cases. Molecular factors are increasingly of prognostic and predictive importance. MRI finding are non specific, but for some tumors are characteristic and suggestive. Gross total resection, when feasible, is the most important treatment in terms of prolonging survival and achieving long-term seizure control. Conformal radiotherapy should be considered in grade 3 and incompletely resected grade 2 tumors. In recurrent tumors reoperation and radiotherapy, including stereotactic radiotherapy, can be useful. Targeted therapies may be used in selected patients: BRAF and MEK inhibitors in pilocytic astrocytomas, pleomorphic xanthoastrocytomas, and gangliogliomas when BRAF altered, and mTOR inhibitor everolimus in subependymal giant cells astrocytomas .Sequencing to identify molecular targets is advocated for diagnostic clarification and to direct potential targeted therapies.

Long-term wellbeing and neurocognitive functioning of diffuse low-grade glioma patients and their caregivers: a longitudinal study spanning two decades

alexandrossfakianakis shared this article with you from Inoreader Long-term wellbeing and neurocognitive functioning of diffuse low-grade glioma patients and their caregivers: a longitudinal study spanning two decades via Neuro-Oncology Advance Access Abstract Background While patients with diffuse low-grade glioma (LGG) often survive for years, there is a risk of tumour progression which may impact on patients' long-term health-related quality of life (HRQOL) and neurocognitive functioning (NCF). We present a follow-up of LGG patients and their informal caregivers (T3) who took part in our previous HRQOL investigations (T1, M=7 and T2 M=13 years after diagnosis). Methods Participants completed HRQOL (SF-36; EORTC-BN20), fatigue (Checklist Individual Strength (CIS)), and depression (Center for Epidemiological Studies-Depression (CES-D)) questionnaires and underwent NCF assessments. T3 scores were compared with matched controls. Change over time (T1-T2-T3) on group and participant level were assessed. Where available, histology of the initial tumour was revised and immunohistochemical staining for IDH1 R 132H mutant protein was performed. Results Thirty patients and nineteen caregivers participated. Of N=11 with tissue available, 3 patients had confirmed diffuse LGG. At T3, patients (M=26 years after diagnosis) had HRQOL and NCF similar to, or better than controls, yet 23.3% and 53.3% scored above the cut-off for depression (≥16 CES-D) and fatigue (≥35 CIS), respectively. Caregivers' HRQOL was similar to controls, but reported high rates of fatigue (63.2%). Over time, patients' mental health improved (p<.05). Minimal detectable change in HRQOL over time was observed in individual patients (30% improvement; 23.3% decline; 20% both improvement and decline) with 23.3% remaining stable. NCF remained stable or improved in 82.8% of patients. Conclusions While HRQOL and NCF do not appear greatly impacted during long-term survivorship in LGG, d epressive symptoms and fatigue are persistent. View on Web

Facial nerve palsy: Narrative review on the importance of the eye and its assessment

alexandrossfakianakis shared this article with you from Inoreader Facial nerve palsy: Narrative review on the importance of the eye and its assessment via Head & Neck Abstract New solutions are emerging that address specific facial regions in facial nerve palsy (FNP). However the most dreaded consequence of FNP is paralytic lagophthalmos threatening the eye. A way to prioritize these regions is thus required. A review of the literature is conduced to capture the current concepts in evaluating FNP. Overall, patients are assessed from three perspectives: from the clinician's perspective using validated clinician-based grading instruments, from patient's perspective based on FNP-specific patient-reported outcome measures, and from the perspective of the layperson. The existing tools however provide limited information regarding the relative importance of different regions of the face. The eye appears to be an area of great concern for the patient where most surgical therapies are directed at. Addressing ocular problems in FNP carry a high priority but this is not clearly reflected by the standard systems. View on Web
