Nutrition impact symptoms and the risk of malnutrition in people with Parkinson's disease: a cross‐sectional study

alexandrossfakianakis shared this article with you from Inoreader Nutrition impact symptoms and the risk of malnutrition in people with Parkinson's disease: a cross‐sectional study via Journal of Human Nutrition and Dietetics Abstract Background People with Parkinson's disease (PD) often experience symptoms that affect their ability to eat. This may contribute to weight loss and increased risk of malnutrition. Objective Our aim was to quantify the extent of nutrition impact symptoms (NIS) in the population and a scoring system of NIS is incorporated in the tool used to identify malnutrition. Methods In this cross-sectional study members of the Norwegian Parkinson's Association, with any PD diagnosis and stage of illness, were invited to respond to an online 24-item questionnaire. Questions from two validated questionnaires, abridged patient-generated subjective global assessment (aPG-SGA) and Radboud Oral Motor Inventory for Parkinson's disease (ROMP), were adapted to an online format. Results The questionnaire was sent to 3047 members, of which 508 persons (17%) responded (61% men). In total, 59% were categorized as well-nourished, 34% at risk of malnutrition a nd 6.5% as malnourished. A quarter of all participants reported symptoms that affected food intake. The most frequent symptoms were constipation (14.2%) and dry mouth (13.4%). On average (SD), malnourished participants reported 3.4 (1.4) symptoms as opposed to 0.1 (0.3) per well-nourished participant. Malnourished participants had more swallowing problems than well-nourished, a mean total ROMP score of 15.5 (6.0) versus 9.0 (2.9) (p <0.001). As the number of points in the ROMP-score increased by one, the points in the aPG-SGA score increased with 37% (95% CI 0.309-0.428). Conclusion Risk of malnutrition was largely related to NIS, especially dysphagia in people with PD. Symptoms affecting food intake should be systematically mapped and treated in conjunction with PD to prevent malnutrition. This article is protected by copyright. All rights reserved. View on Web

Incidence, risk factors, outcomes, and clinical management of BK viremia in the modern era of kidney transplantation

alexandrossfakianakis shared this article with you from Inoreader Incidence, risk factors, outcomes, and clinical management of BK viremia in the modern era of kidney transplantation via Transplant Infectious Disease ABSTRACT Background : BK viremia is endemic among kidney transplant recipients (KTR). Incidence, risk factors, outcomes, and clinical management of detectable versus high BK viremia have not been considered previously in KTR in the modern era. Methods : This observational study examined KTR transplanted between January 1, 2009 and December 31, 2016. Any BK viral load in the serum constituted detectable BK viremia and ≥103 copies/mL constituted high viremia. Results : Among 1,193 KTR, the cumulative probability of developing detectable and high BK viremia within two years post-transplant were 27.8% and 19.6%, respectively. Significant risk factors for detectable BK viremia included recipient age (HR 1.02 [95% CI: 1.01, 1.03]) and donor age (HR 1.01 [95% CI: 1.00, 1.02]). Recipient age also predicted high BK viremia (HR 1.02 [95% CI: 1.01, 1.03]), whereas White race (HR 0.70 [95% CI: 0.52, 0.95]), non-depleting induction therapy (HR 0.61 [95% CI: 0.42, 0.89]), and delayed graft function (HR 0.61 [95% CI: 0.42, 0.88]) were protective. Mean estimated glomerular filtration rates were 4.28 mL/min/1.72 m2 (95% CI: 2.71, 5.84) lower with detectable BK viremia. Although low viral load was usually not acted upon at first presentation, anti-proliferative dose reductions were the most common initial management. Conclusion : BK viremia remains a common early complication in a modern cohort of KTR. These findings highlight the benefit of early BKV monitoring in addition to intensive clinical management. Clinical responses beyond first positive BK viremia tests, and their implications for graft outcomes, merit further investigation. This article is protected by copyright.

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

Genomic Annotation and Molecular Evolution of Monkeypox Virus Outbreak in 2022

alexandrossfakianakis shared this article with you from Inoreader Genomic Annotation and Molecular Evolution of Monkeypox Virus Outbreak in 2022 via Journal of Medical Virology ABSTRACT Monkeypox virus (MPXV) has generally circulated in West and Central Africa since its emergence. Recently, sporadic MPXV infections in several non-endemic countries have attracted widespread attention. Here, we conducted a systematic analysis of the recent outbreak of MPXV-2022, including its genomic annotation and molecular evolution. The phylogenetic analysis indicated that the MPXV-2022 strains belong to the same lineage of the MPXV strain isolated in 2018. However, compared with the MPXV strain in 2018, in total 46 new consensus mutations were observed in the MPXV-2022 strains, including 24 non-synonymous mutations. By assigning mutations to 187 proteins encoded by the MPXV genome, we found that ten proteins in the monkeypox virus are more prone to mutation, including D2L-like, OPG023, OPG047, OPG071, OPG105, OPG109, A27L-like, OPG153, OPG188, and OPG210 proteins. In the MPXV-2022 strains, 4 and 3 nucleotide substitutions are observed in OPG105 and OPG210 , respectively. Overall, our studies illustrated the genome evolution of the ongoing MPXV outbreak and pointed out novel mutations as a reference for further studies. This article is protected by copyright.

Case volume regionalization and volume‐based outcome differences in cutaneous head and neck melanoma

alexandrossfakianakis shared this article with you from Inoreader Case volume regionalization and volume‐based outcome differences in cutaneous head and neck melanoma via Head & Neck Abstract Background Hospital volume has emerged as a prognostic factor in oncology but is not currently known whether volume is associated with improved outcomes for cutaneous head and neck (HN) melanoma. Methods A total of 556 079 cutaneous melanoma cases reported by the 2004–2016 National Cancer Database were separated into two cohorts (HN and non-HN) and facilities within each cohort were classified by case volume. Analysis employed chi-square, analysis of variance, Kaplan–Meier, and Cox proportional hazards models. Results Only 41 facilities (3.1% of 1326) treating HN melanoma and 50 facilities (3.7% of 1344) treating non-HN melanoma were classified as high-volume facilities (HVFs). The estimated 5-year overall survival (OS) was 62.7% (standard error [SE]: 0.4%) for patients with HN at low-volume facilities (LVFs), 69.3% (SE: 0.4%) at IVFs, and 71.8% (SE 0.4%) at HVFs (p < 0.001). Differences in OS remained significant between HVFs versus LVFs after adjusting for confounders. Conclusion Volume is independently associated with OS and improved surgical outcomes for HN melanoma.

Menopausal hormone therapy and subclinical cardiovascular disease in women with and without HIV

alexandrossfakianakis shared this article with you from Inoreader Menopausal hormone therapy and subclinical cardiovascular disease in women with and without HIV via Clinical Infectious Diseases Advance Access Abstract Background Estrogen-based hormone therapy (HT) may have beneficial cardiovascular effects when initiated in early menopause. This has not been examined in women with HIV who have heightened immune activation and cardiovascular risks. Methods Among 609 post-menopausal women (1,234 person-visits) in the Women's Interagency HIV Study, we examined the relationship of ever HT use (oral, patch, or vaginal) with subclinical atherosclerosis – carotid artery intima-media thickness (CIMT), distensibility, and plaque assessed via repeated B-mode ultrasound imaging (2004-2013). We also examined associations of HT with cross-sectional biomarkers of immune activation and D-dimer. Statistical models were adjusted for sociodemographic, behavioral, and cardiometabolic factors. Results Women (mean age = 51, 80% HIV+) who ever used HT at baseline were older, and more likely to be non-Hispanic White and report higher income, than never users. Women who ever used HT had 43% lower prevalence of plaque (prevalence ratio = 0.57; 95% CI = [0.40, 0.80]; p < 0.01), 2.51 µm less progression of CIMT per year (95% CI = [-4.60, -0.41]; p = 0.02), and marginally lower incidence of plaque over ∼7 years (risk ratio = 0.38; 95% CI = [0.14, 1.03]; p = 0.06), compared with never users, adjusting for covariates; ever HT use was not associated with distensibility. These findings were similar for women with and without HIV. Ever HT use was associated with lower serum D-dimer, but not with biomarkers of immune activation after covariate adjustment. Conclusions HT may confer a subclinical cardiovascular benefit in women with HIV. These results begin to fill a knowledge gap in menopausal care for women with HIV, in whom uptake of HT is very low.

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.

Empiric versus pre-emptive antifungal strategy in high-risk neutropenic patients on fluconazole prophylaxis: a randomized trial of the European organization for Research and Treatment of cancer (EORTC 65091)

alexandrossfakianakis shared this article with you from Inoreader Empiric versus pre-emptive antifungal strategy in high-risk neutropenic patients on fluconazole prophylaxis: a randomized trial of the European organization for Research and Treatment of cancer (EORTC 65091) via Clinical Infectious Diseases Advance Access Abstract Background Empiric antifungal therapy is considered the standard-of-care for high-risk neutropenic patients with persistent fever. The impact of a pre-emptive, diagnostic-driven approach based on galactomannan (GM) screening and chest CT-scan on demand on survival and on the risk of invasive fungal disease (IFD) during the first weeks of high-risk neutropenia is unknown. Methods Patients with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS) and allogeneic hematopoietic cell transplant recipients were randomly assigned to receive caspofungin empirically (Arm A) or pre-emptively (Arm B). All patients received fluconazole 400 mg daily as prophylaxis. The primary endpoint of this non-inferiority study was overall survival (OS) 42 days after randomization. Results Of 556 patients recruited, 549 were eligible: 275 in Arm A, 274 in Arm B. Eighty percent of the patients had AML or MDS requiring high-dose chemothe rapy and 93% of them were in first induction phase. At day 42, the OS was not inferior in Arm B (96.7%; 95% confidence interval (CI), 93.8 - 98.3%) when compared to Arm A (93.1%; 95% CI, 89.3 - 95.5%). The rates of IFDs at day 84 were not significantly different, 7.7% (95%CI, 4.5–10.8%) in Arm B versus 6.6% (95%CI, 3.6–9.5%) in Arm A, respectively. The rate of patients receiving caspofungin was significantly lower in Arm B (27%) than in Arm A (63%) (p < 0.001). Conclusions The pre-emptive antifungal strategy was safe for high-risk neutropenic patients given fluconazole as prophylaxis, halving the number of patients receiving antifungals without excess mortality or IFDs.

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.
