Patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Greatly Improved Fatigue Symptoms When Treated with Oxygen-Ozone Autohemotherapy

(1) Background: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a chronic syndrome characterized by fatigue as its major and most outstanding symptom. Previous evidence has supported the ability of ozone to relief ME/CFS related fatigue in affected patients (2) Methods: A number of 200 ME/CFS previously diagnosed patients, (mean age 33 ± 13 SD years) were consecutively treated with oxygen-ozone autohemotherapy (O2-O3-AHT). Fatigue was evaluated via an FSS 7-scoring questionnaire before and following 30 days after treatment. (3) Results: Almost half (43.5%) of the treated patients evolved their FSS scale from the worst (7) to the best (1) score, assessing the highest improvement from being treated with O2-O3-AHT. Furthermore 77.5% of patients experienced significant ameliorations of fatigue, of 4–6 delta score. No patient showed side effects, yet experienced long lasting fatigue disappearance, by three months follow up (4) Conclusions: Treatment with O2-O3-AHT greatly improves ME/CFS related fatigue, aside from sex and age distribution.

A Randomized Controlled Trial of Simulation Training in Teaching Coronary Angiographic Views

IntroductionSimulation technology has an established role in teaching technical skills to cardiology fellows, but their impact on teaching trainees to interpret coronary angiographic (CA) images has not been systematically studied. The aim of this randomized controlled study was to test whether structured simulation training in addition to traditional methods would improve CA image interpretation skills in a group of novices to advanced medical trainees.MethodsWe prospectively randomized 105 subjects comprising of medical students (N=20), residents (N=68) and fellows (N=17) from the University of Arizona. Subjects were randomized into a simulation training group which received simulation training in addition to didactic teaching (n=53) and a control training group which received didactic teaching alone (n=52). The change in pre and post-test score (delta score) was analyzed by a two-way ANOVA for education status and training arm.ResultsSubjects improved in their post-test scores with a mean change of 4.6 ± 4.0 points. Subjects in the simulation training arm had a higher delta score compared to control (5.4 ± 4.2 versus 3.8 ± 3.7, p=0.04), with greatest impact for residents (6.6 ± 4.0 versus 3.5 ± 3.4) with a p=0.02 for interaction of training arm and education status.ConclusionsSimulation training complements traditional methods to improve CA interpretation skill, with greatest impact on novice trainees. This highlights the importance of incorporating high-fidelity simulation training early in cardiovascular fellowship curricula.

Adolescents with cancer on privacy: Fact-finding survey on the need for confidentiality and space

Background: Cancer diagnosis and related treatment can limit young patients’ privacy. Their need for private physical and psychological spaces can be impeded by limited freedom, e.g., sharing hospital rooms with others and exposing their body to their parents and doctors. Methods: We conducted a survey among young patients of our center to investigate how their perception of privacy changed after being diagnosed with cancer and their need for hospital dedicated physical spaces and time for patients to enjoy their privacy. A questionnaire with 16 items was developed by the staff involving psychologists and physicians. The relevance of changes before and after the cancer diagnosis was assessed by calculating two scores indicating the situation before and after diagnosis for each answer, as well as a delta score. Results: Between May and June 2020, the questionnaire was completed by 60 patients aged 16–24 years. The median delta scores describing the changes before and after diagnosis were −8 points for perception of privacy, indicating a significant decrement of the level of privacy perceived. A major issue was the constant presence of parents being perceived as intrusive. Concerning hospital dedicated physical spaces and time for patients to enjoy their privacy, respondents requested dedicated spaces (50% of patients) and opportunities to have private interviews with medical personnel (88%). Conclusions: Our study offers a snapshot of how young people with cancer perceive the impact of the disease and its treatment on their privacy with the restrictions imposed on their individual freedom. Patients’ personal needs must be taken into consideration to adopt appropriate measures and better organize wards.

Discrepancy-Based Evidence for Loss of Thinking Abilities (DELTA): Development and Validation of a Novel Approach to Identifying Cognitive Changes

Objective:To develop and validate the Discrepancy-based Evidence for Loss of Thinking Abilities (DELTA) score. The DELTA score characterizes the strength of evidence for cognitive decline on a continuous spectrum using well-established psychometric principles for improving detection of cognitive changes.Methods:DELTA score development used neuropsychological test scores from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) cohort (two tests each from Memory, Executive Function, and Language domains). We derived regression-based normative reference scores using age, gender, years of education, and word-reading ability from robust cognitively normal ADNI participants. Discrepancies between predicted and observed scores were used for calculating the DELTA score (range 0–15). We validated DELTA scores primarily against longitudinal Clinical Dementia Rating-Sum of Boxes (CDR-SOB) and Functional Activities Questionnaire (FAQ) scores (baseline assessment through Year 3) using linear mixed models and secondarily against cross-sectional Alzheimer’s biomarkers.Results:There were 1359 ADNI participants with calculable baseline DELTA scores (age 73.7 ± 7.1 years, 55.4% female, 100% white/Caucasian). Higher baseline DELTA scores (stronger evidence of cognitive decline) predicted higher baseline CDR-SOB (ΔR2 = .318) and faster rates of CDR-SOB increase over time (ΔR2 = .209). Longitudinal changes in DELTA scores tracked closely and in the same direction as CDR-SOB scores (fixed and random effects of mean + mean-centered DELTA, ΔR2 > .7). Results were similar for FAQ scores. High DELTA scores predicted higher PET-Aβ SUVr (ρ = 324), higher CSF-pTau/CSF-Aβ ratio (ρ = .460), and demonstrated PPV > .9 for positive Alzheimer’s disease biomarker classification.Conclusions:Data support initial development and validation of the DELTA score through its associations with longitudinal functional changes and Alzheimer’s biomarkers. We provide several considerations for future research and include an automated scoring program for clinical use.

Phylogeny in Phonology: How Tai Sound Systems Encode Their Past

The study of sound change is foundational to traditional historical linguistics, particularly the linguistic comparative method. It is well established that the phonology of modern languages encodes useful data for studying the history of those languages, and their genetic relationships to one another. However, phonology has typically been the means to the end, enabling the comparative method, and coding of a comparative lexicon for cognacy. Once coded, the particular sounds involved no longer factor into the analysis. This study examines whether the phoneme inventories and phonotactic profiles of a set of languages themselves contain phylogenetic signal detectable using established statistical tests D statistic (Fritz & Purvis 2010), K (Blomberg et al 2003), and NeighborNet delta score (Holland et al 2002) and Q-residual (Gray et al 2010). This study adds to the growing body of work on the use of phonological traits in computational phylogenetics for linguistics. Using data from 20 Tai lects from the Kra-Dai language family, this study confirms and extends previous findings. This includes detection of strong phylogenetic signal in phoneme frequency and biphone transition probabilities, but also relatively strong phylogenetic signal detected in even coarse-grained phoneme and biphone presence/absence, which previous work was unable to do.

Efficacy of intensive multidisciplinary rehabilitation in Parkinson’s disease: a randomised controlled study

ObjectiveTo evaluate whether a 4-week multidisciplinary, aerobic, motor-cognitive and intensive rehabilitation treatment (MIRT) improves the quality of life (QoL) of patients with Parkinson’s disease (PD), in the short-term and long-term period.MethodsThis is a prospective, parallel-group, single-centre, single-blind, randomised clinical trial (ClinicalTrials.gov NCT02756676). 186 patients with PD, assigned to experimental group, underwent MIRT; conversely, 48 patients, assigned to control group, did not receive rehabilitation. Parkinson’s Disease Questionnaire-39 was assessed 2 (T0), 10 (T1) and 18 (T2, only experimental group) weeks after the enrolment. We compared T1 versus T0 scores within subjects and delta scores (T1–T0) between subjects. To investigate the long-term effects, we compared T2 and T0 scores in the experimental group.ResultsAt T0, no between-group differences in the Global Index Score (GBI) were observed (experimental group: 43.6±21.4, controls: 41.6±22.9, P=0.50). At T1, we did not find significant changes in controls (delta score: 1.2±9.9, P=0.23), and we found an improvement in GBI in the experimental group (delta score: −8.3±18.0, P<0.0001), significant also between subjects (P<0.0001). Comparing T2 versus T0 in the experimental group, the GBI maintained a significant improvement (delta score: −4.8±17.5, P<0.0001).ConclusionsA rehabilitation treatment such as MIRT could improve QoL in patients with PD in the short-term and long-term period. Even though the single-blind design and the possible role of the placebo effect on the conclusive results must be considered as limitations of this study, the improvement in outcome measure, also maintained after a 3-month follow-up period, suggests the effectiveness of MIRT on the QoL.Clinical trial registrationNCT02756676: Pre-results.
