RESUMEN

The missense mutation p.R406W in microtubule-associated protein tau leads to frontotemporal lobar degeneration with an amnestic, Alzheimer's disease-like phenotype with an autosomal dominant pattern of inheritance. In 2003, we described the pedigree of a Belgian family, labelled ADG, with 28 p.R406W patients. Over 18 years follow-up, we extended the family with 10 p.R406W carriers and provided an in-depth clinical description of the patients. Additionally, genetic screening was used to identify p.R406W carriers in Belgian cohorts of frontotemporal dementia and Alzheimer's disease patients and to calculate p.R406W frequency. In the frontotemporal dementia cohort, we found four p.R406W carriers (n = 647, 0.62%) and three in the Alzheimer's disease cohort (n = 1134, 0.26%). Haplotype sharing analysis showed evidence of a shared haplotype suggesting that they are descendants of a common ancestor. Of the p.R406W patients, we describe characteristics of neuropsychological, imaging and fluid biomarkers as well as neuropathologic examination. Intriguingly, the phenotypic spectrum among the p.R406W patients ranged from typical behavioural variant frontotemporal dementia to clinical Alzheimer's disease, based on CSF biomarker analysis and amyloid PET scan. Heterogeneous overlap syndromes existed in between, with highly common neuropsychiatric symptoms like disinhibition and aggressiveness, which occurred in 100% of frontotemporal dementia and 58% of clinical Alzheimer's disease patients. This was also the case for memory problems, 89% in frontotemporal dementia and 100% in clinical Alzheimer's disease patients. Median age at death was significantly lower in patients with frontotemporal dementia (68 years) compared to clinical Alzheimer's disease patients (79 years), although the sizes of the sub-cohorts are limited and do not allow prognostic predictions. Post-mortem brain analysis of one p.R406W patient with behavioural variant frontotemporal dementia revealed frontotemporal lobar degeneration with tau pathology. Notably, neuropathological investigation showed only 3R tau isoforms in the absence of 4R tau reactivity, an unusual finding in microtubule-associated protein tau-related frontotemporal lobar degeneration. No traces of amyloid pathology were present. Prevalence of the p.R406W mutation was relatively high in both frontotemporal dementia and Alzheimer's disease Belgian patient cohorts. These findings grant new insights into genotype-phenotype correlations of p.R406W carriers. They may help in further unravelling of the pathophysiology of this tauopathy and in facilitating the identification of patients with p.R406W-related frontotemporal lobar degeneration, both in clinical diagnostic and research settings.

RESUMEN

The coronavirus (COVID-19) pandemic represented a critical moment for technology use within rehabilitation counseling. This study explored trends in the beliefs and behaviors of certified rehabilitation counselors (CRCs) regarding the ethical use of technology before and during the pandemic. Specifically, this study compared two groups of CRCs regarding the degree to which they engaged in 59 technology behaviors and whether they viewed each behavior to be ethical. Overall, group comparisons suggested an increased use of telephone, videoconferencing, and email to deliver counseling, assessment, and supervision services during the pandemic. Furthermore, supervision via videoconferencing and email in the pandemic were rated as more ethically appropriate than before the pandemic. As a general trend, synchronous modes of communication such as the telephone and video conferencing were rated as more ethically appropriate than asynchronous modes such as social networking and text messaging. Indicating a high degree of congruence between beliefs and behaviors, the technology practices viewed as most ethical were used the most often. Implications address the revisions to the Code of Professional Ethics for Rehabilitation Counselors regarding the ethical use of technology in rehabilitation counseling.

RESUMEN

IMPORTANCE: Despite criticisms of disability simulation and the limited research on the topic, disability simulation activities are often used to increase understanding of the challenges faced by people with disabilities. OBJECTIVE: To compare two disability awareness activities (disability simulation and an accessibility audit). DESIGN: A matched pretest-posttest design with two disability awareness activities to study attitudes, affect, cognitions, and behaviors toward disability. SETTING: A small college in New England. PARTICIPANTS: Eighty-eight undergraduate students. INTERVENTION: Participants took baseline tests online, after which they participated in a 1-hr on-campus activity. Participants were randomly assigned to either the disability simulation activity or the accessibility audit activity. Participants took posttest surveys online within 1 wk of completing the intervention. RESULTS: Results demonstrated that both activities lowered negative emotional responses toward people with disabilities, but participants who completed the tape measure activity had a larger decrease in scores. No significant differences were found between the scores of people who completed the different disability awareness activities. CONCLUSIONS: Given the many criticisms of disability simulation practices and marginal differences between activities, it is time for disability simulation activities to be retired from use. WHAT THIS ARTICLE ADDS: The results of this study demonstrate that disability simulation is no better than an accessibility audit in improving attitudes toward people with disabilities. Therefore, educators should cease use of these activities.

RESUMEN

Screening of the antifungal activities of ten Guadeloupean plants was undertaken to find new extracts and formulations against superficial mycoses such as onychomycosis, athlete's foot, Pityriasis versicolor, as well as the deep fungal infection Pneumocystis pneumonia. For the first time, the CMI of these plant extracts [cyclohexane, ethanol and ethanol/water (1:1, v/v)] was determined against five dermatophytes, five Candida species, Scytalidium dimidiatum, a Malassezia sp. strain and Pneumocystis carinii. Cytotoxicity tests of the most active extracts were also performed on an HaCat keratinocyte cell line. Results suggest that the extracts of Bursera simaruba, Cedrela odorata, Enterolobium cyclocarpum and Pluchea carolinensis have interesting activities and could be good candidates for developing antifungal formulations.

RESUMEN

BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) improves motor and non-motor symptoms in patients with advanced Parkinson's disease (aPD). OBJECTIVE: To present the final 36-month efficacy and safety results from DUOGLOBE (DUOdopa/Duopa in Patients with Advanced Parkinson's Disease - a GLobal OBservational Study Evaluating Long-Term Effectiveness; NCT02611713). METHODS: DUOGLOBE was an international, prospective, long-term, real-world, observational study of patients with aPD initiating LCIG in routine clinical care. The primary endpoint was change in patient-reported "Off" time to Month 36. Safety was assessed by monitoring serious adverse events (SAEs). RESULTS: Significant improvements in "Off" time were maintained over 3 years (mean [SD]: -3.3 hours [3.7]; p < 0.001). There were significant improvements to Month 36 in total scores of the Unified Dyskinesia Rating Scale (-5.9 [23.7]; p = 0.044), Non-Motor Symptoms Scale (-14.3 [40.5]; p = 0.002), Parkinson's Disease Sleep Scale-2 (-5.8 [12.9]; p < 0.001), and Epworth Sleepiness Scale (-1.8 [6.0]; p = 0.008). Health-related quality of life and caregiver burden significantly improved through Months 24 and 30, respectively (Month 24, 8-item Parkinson's Disease Questionnaire Summary Index, -6.0 [22.5]; p = 0.006; Month 30, Modified Caregiver Strain Index, -2.3 [7.6]; p = 0.026). Safety was consistent with the well-established LCIG profile (SAEs: 54.9% of patients; discontinuations: 54.4%; discontinuations due to an adverse event: 27.2%). Of 106 study discontinuations, 32 patients (30.2%) continued LCIG outside the study. CONCLUSION: DUOGLOBE demonstrates real-world, long-term, reductions in motor and non-motor symptoms in patients with aPD treated with LCIG.

RESUMEN

BACKGROUND: It is believed that motor symptoms, including dyskinesia, and non-motor symptoms impact health-related quality of life (HRQoL) in patients with Parkinson's disease (PD), and that improvements in these metrics are correlated. OBJECTIVE: Investigate the relationship between HRQoL and measures of PD severity and treatment efficacy, including motor and non-motor symptoms. METHODS: This was a planned investigation of an international, prospective, single-arm, post-marketing observational study of the long-term effectiveness of levodopa-carbidopa intestinal gel (LCIG) in patients with advanced PD. Pearson correlation coefficients (PCC) were calculated for baseline and change from baseline at 12 months between HRQoL and motor and non-motor symptoms. RESULTS: A total of 195 patients were included. At baseline, HRQoL was moderately positively correlated with Activities of Daily Living (UPDRS II, PCC = 0.44), non-motor symptoms (0.48), and measures of sleep (0.50 and 0.40); all p < 0.001. After 12 months of treatment with LCIG, improvements in HRQoL were moderately positively correlated with improvement from baseline in non-motor symptoms (PCC = 0.42), sleep (0.54), and daytime sleepiness (0.40; all p < 0.001), and weakly correlated with improvement in dyskinesia signs and symptoms (PCC = 0.23; p = 0.011). Improvement in HRQoL was not correlated with improvements in OFF time or dyskinesia time. CONCLUSION: Both at baseline and for change from baseline at 12 months, HRQoL was correlated with baseline and change from baseline in dyskinesia, Activities of Daily Living, and non-motor symptoms, including sleep; but not with baseline or change in OFF time.

RESUMEN

BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) is an established treatment for improving motor and some non-motor symptoms (NMS) in patients with advanced Parkinson's disease (PD). Prospective long-term data in routine clinical practice are limited. OBJECTIVE: Assess LCIG effectiveness and safety in patients with advanced PD after 12 months during real-world routine clinical practice. METHODS: Duodopa/Duopa in patients with advanced Parkinson's disease-a global observational study evaluating long-term effectiveness (DUOGLOBE) (NCT02611713) is an ongoing, prospective, multinational, observational study of LCIG-naïve patients treated as part of routine clinical practice; 3 years of follow-up are planned. The primary outcome is the change in patient-reported off time. Other assessments include the Unified Dyskinesia Rating Scale (UDysRS), Non-Motor Symptoms Scale (NMSS), Parkinson's Disease Sleep scale (PDSS-2), Epworth Sleepiness Scale (ESS), health-related quality of life (HR-QoL), caregiver burden, and serious adverse events (SAEs). Outcomes from baseline to month (M) 12 are presented. RESULTS: In this 12-month follow-up, patients (N = 195) had baseline characteristics similar to other LCIG studies. Significant improvements (mean change to M12) were observed in off time (-3.9 ± 3.6 hr/day, P < 0.001), dyskinesia assessed using the UDysRS (-9.6 ± 22.5, P < 0.001), NMSS (-23.1 ± 41.4, P < 0.001), sleep and sleepiness symptoms on the PDSS-2 (-6.5 ± 12.2, P < 0.001) and ESS (-1.0 ± 5.7, P < 0.05), HR-QoL (-9.0 ± 21.6, P < 0.001), and caregiver burden (-1.9 ± 6.7, P = 0.008). Overall, 40.5% (n = 79) of patients experienced SAEs; fall (n = 6; 3.1%) and urinary tract infection (n = 6; 3.1%) were SAEs reported in ≥3% of patients. CONCLUSIONS: These 12-month outcome data show sustained, long-term improvements and support the real-world effectiveness of LCIG in patients with advanced PD. Safety was consistent with previous studies.

RESUMEN

Aim: A Delphi expert consensus panel proposed that fulfilling ≥1 of the '5-2-1 criteria' (≥five-times daily oral levodopa use, ≥two daily hours with 'Off' symptoms or ≥one daily hour with troublesome dyskinesia) suggests advanced Parkinson's disease (PD). Patients & methods: DUOdopa/Duopa in Patients with Advanced PD - a GLobal OBservational Study Evaluating Long-Term Effectiveness (DUOGLOBE) - is a single-arm, postmarketing, observational, long-term effectiveness study of levodopa-carbidopa intestinal gel (LCIG) for advanced PD. Results: This 6-month interim analysis (n = 139) affirms that most (98%) enrolled patients fulfill ≥1 of the 5-2-1 criteria. These patients responded favorably to LCIG treatment. Safety was consistent with other LCIG studies. Conclusion: In advanced PD patients, the 5-2-1 criteria generally aligns with clinician assessment. Clinical Trial Registration: NCT02611713 (ClinicalTrials.gov).

RESUMEN

A new bicoumarin (3) was isolated from the leaves and stems of Triphasia trifolia. Its structure was determined by spectral data, in particular two-dimensional NMR experiments. It appeared that the two coumarinic moieties of 3 are derivatives of mexoticin (1) and meranzin hydrate (2), which are known constituents of the plant.

RESUMEN

The composition of the kernel oils of two Calophyllum species (Calophyllum calaba L. and Calophyllum inophyllum L.) was investigated. The physico-chemical properties and fatty acid composition of the kernel oils were examined. In two species, oleic acid C18:1 (39.1-50%) is the dominating fatty acid followed by linoleic acid C18:2 (21.7-31.1%) as the second major fatty acid. Stearic C18:0 (13.4-14.3%) and palmitic C16:0 (11-13.7%) acids are the major saturates. The oils contains an appreciable amount of unsaturated fatty acids (70.8-73.10%). Most of the fatty acids are present as triacylglycerol (76.7-84%), twenty one triacylglycerols are detected with predominantly unsaturated triacylglycerols. The total unsaponifiable content, its general composition and the identity of the components of the sterol and tocopherol fractions are presented. In both species, analysis of the unsaponifiable fractions revealed the preponderance of phytosterols, mainly stigmasterol (35.8-45.1%) and beta-sitosterol (41.1-43.1%). Among the eight tocopherols and tocotrienols present in two species, variations exist; alpha-tocopherol (183 mg/kg) is the main tocopherol in Calophyllum calaba L. and Delta-tocotrienol (236 mg/kg) is the dominant tocotrienol in Calophyllum inophyllum L.

RESUMEN

Wastes produced during fermentation and distillation of crude sugarcane juice in rum factories were evaluated as a new source of waxes. The chemical composition of the crude wax extracted from adsorbat of the wastes on fuller's earth was studied by GC-mass spectrometry. Series of linear alkanes (C19-C33), and wax esters constitute the main components. In addition, phytosterols, triterpene methyl ethers, ethyl and methyl esters of fatty acids, and free fatty acids were found as minor components. Acid (predominance of C16 and C18) and alcohol portions (C26-C32) of the wax esters were analysed after saponification.
