Evaluation of Eye Movement Desensitization and Reprocessing in the management of tinnitus. An observational study

ObjectivesTinnitus can induce disabling psychological suffering, requiring an integrative multimodal approach, combining neuromodulation and psychotherapeutic methods. We sought to evaluate the therapeutic efficacy and acceptability of Eye Movement Desensitization and Reprocessing (EMDR) in tinnitus.Materials and methodsThis was a single-center prospective non-comparative study. Inclusion criteria comprised: adult patient, with chronic tinnitus, Tinnitus Handicap Inventory (THI) score > 17, causing psychological distress motivating active treatment after ineffective “classic” treatment (combining advice, sound therapy and first-line drug treatment), and agreement to EMDR therapy. Therapeutic efficacy was defined by a decrease in THI or Visual Analog Scale (VAS) scores. Treatment acceptability was defined by the rate of included patients who completed therapy.ResultsThirty-eight patients were included. There was a significant reduction of 53.5% in THI score in 78.9% of patients (P < 0.0001; 64.8 ± 20.8 before versus 31.8 ± 24.7 after treatment), and of 51% in VAS score in 76.3% of patients (P < 0.0001; 7.24 ± 2.12 before versus 3.58 ± 2.03 after treatment). The treatment acceptability was 86.8%.ConclusionEMDR appeared to be an effective alternative that was acceptable to the majority of patients, after failure of “classic” first-line treatment, improving quality of life in tinnitus patients and thus relieving disability.     

Subchondroplasty in the treatment of bone Marrow lesion in early Knee Osteoarthritis: A systematic review of clinical and radiological outcomes

BackgroundKnee osteoarthritis (KOA) is increasingly prevalent in North American society. The significant societal burden it represents makes it essential to promote and target new treatments in earlier phases of the disease. Among others, subchondroplasty is a newly documented technique using calcium phosphate injection targeting the osteochondral lesions preceding KOA, also known as Bone Marrow Lesions (BMLs). This article aimed to review the existing literature on clinical and radiological outcomes of subchondroplasty in the treatment of BMLs in KOA.MethodA systematic review was performed using PubMed, Embase, Medline and Cochrane Database of Systematic Reviews. Studies on calcium phosphate injections into BMLs for KOA and its clinical and radiological outcomes were screened and reviewed by independent evaluators.ResultsAfter screening, ten articles were included, totaling 540 patients. Follow-up ranged from 6 months to 7 years. Overall, the procedure showed significant functional and quality of life improvement, as well as pain relief, as shown by Patients-Reported Outcomes Measures (PROMs). There were very few complications reported, the most important being leakage of calcium phosphate outside the targeted site. Conversion rate to total knee arthroplasty (TKA) ranged from 14 % to 30 % at 2 years post-procedure. Long term radiological outcomes have been poorly documented.ConclusionsSubchondroplasty is a promising avenue for the treatment of KOA. However, quality evidence is still required before any real conclusions and practical management guidelines can be drawn. Prospective, randomized studies with a control group and a rigorous assessment of long-term clinical and radiological outcomes are recommended.     

Preprocessor Adapts Cardiovascular Signals to a Minicomputer

A laboratory-developed analog signal processor, driven by a conventional polygraph recorder and associated signal conditioning devices, provides automatic heart beat-by-heart beat preprocessing of various cardiovascular functions for input to a laboratory-type minicomputer. The technique of preprocessing individual functions, integrated with the minicomputer system which includes an A/D converter and teletype as input-output peripherals, provides a low-cost data acquisition and reduction system for the on-line computation and analysis of cardiovascular functions in experimental research applications. Such preprocessing more efficiently uses the minicomputer's memory to handle large amounts of information since the digitized data is in the form of one data sample, per function, per heart beat. Preprocessing analog data provides a low density data format and simplified software programs that are ideally suited for the utilization of a minicomputer in this on-line application.     

Simulation of cardiovascular physiology: the diastolic function(s) of the heart

The cardiovascular system was simulated by using an equivalent electronic circuit. Four sets of simulations were performed. The basic variables investigated were cardiac output and stroke volume. They were studied as functions (i) of right ventricular capacitance and negative intrathoracic pressure; (ii) of left ventricular relaxation and of heart rate; and (iii) of left ventricle failure. It seems that a satisfactory simulation of systolic and diastolic functions of the heart is possible. Presented simulations improve our understanding of the role of the capacitance of both ventricles and of the diastolic relaxation in cardiovascular physiology.     

Efficacy of myofascial therapy and kinesitherapy in improving function in shoulder pathology with prolonged immobilization: A randomized,single-blind,controlled trial

BackgroundThe best physiotherapeutic approach in shoulder pathology that generates prolonged immobilization is still uncertain. Kinesitherapy remains the most widely used option. Myofascial therapy is a therapeutic approach in which the aim is to release fascial tension and regain mobility although its efficacy in shoulder pathology has not been sufficiently studied. This Prospective, single-blind randomized controlled trial in a university hospital setting aimed to compare the efficacy of myofascial therapy and kinesitherapy in improving function in shoulder pathology with prolonged immobilization.MethodsPatients were randomly assigned to a control group or to the intervention group.Both groups completed a therapeutic exercise program. Main Outcome Measures: The QuickDash questionnaire was the primary outcome, Pain Visual Analog Scale and the Range Of Motion of the shoulder were the secondary outcomes. The outcomes were evaluated at baseline (T0), at 4 (T2), 8 (T2), and 12 weeks (T3)Results44 participants were included. In the analysis of evolution over time, a significant improvement in functionality and range of motion measurements was observed in both groups (p < 0.05), although at 12 weeks only Myofasical Group achieved a clinically and statistically significant reduction in pain. Comparative analysis at 12 weeks revealed no statistically significant differences between the two therapies in the variables explored.ConclusionsBoth, myofascial therapy and kinesitherapy can improve function, mobility, and pain in patients with painful shoulder associated with prolonged immobilization, with no significant differences between therapies, although in the medium term only myofascial therapy achieves a clinically and statistically significant improvement in pain.Trial registrationTrial registration: ClinicalTrials.gov NCT04944446.     

Numerical Architecture

The idea that there is a “Number Sense” (Dehaene, 1997) or “Core Knowledge” of number ensconced in a modular processing system (Carey, 2009) has gained popularity as the study of numerical cognition has matured. However, these claims are generally made with little, if any, detailed examination of which modular properties are instantiated in numerical processing. In this article, I aim to rectify this situation by detailing the modular properties on display in numerical cognitive processing. In the process, I review literature from across the cognitive sciences and describe how the evidence reported in these works supports the hypothesis that numerical cognitive processing is modular. I outline the properties that would suffice for deeming a certain processing system a modular processing system. Subsequently, I use behavioral, neuropsychological, philosophical, and anthropological evidence to show that the number module is domain specific, informationally encapsulated, neurally localizable, subject to specific pathological breakdowns, mandatory, fast, and inaccessible at the person level; in other words, I use the evidence to demonstrate that some of our numerical capacity is housed in modular casing.

Fatigue,anxiety and depression overrule the role of oncological treatment in predicting self-reported health complaints in women with breast cancer compared to healthy controls

BackgroundWomen with breast cancer often attribute their health problems as side effects caused by oncological treatments. The aim of the study was to examine and compare self-reported health complaints (SHC) in postmenopausal patients with breast cancer to healthy controls.MethodWomen with breast cancer (N = 196) filled in 5 questionnaires 1–2 years after surgery; SHC Inventory, Functional Assessment of Cancer Therapy-Endocrine Subscale (FACT-ES), Fatigue – Functional Assessment of Cancer Therapy-Fatigue subscale (FACIT-F), Fatigue Visual Analog Scale (Fatigue VAS), and Hospital Anxiety and Depression Scale (HADS). Controls comprised 101 blood donors who reported on the questionnaires except for HADS. Bonferroni adjustment and p < 0.0017 was considered statistically significant for SHC Inventory, p < 0.05 for the remaining questionnaires.ResultsThe patients, mean age 58.0 (SD 9.5), reported significantly more self-reported health complaints, whereof 6 of 29 complaints were significantly elevated compared to the controls, mean age 57.0 (SD 5.8) (p < 0.001). HADS scores in patients fell into normal range, mean 6.3 (SD 5.7). A subgroup of 48 patients experienced more frequent and severe symptoms in all the questionnaires compared to the remaining 148 patients, and the 101 controls. Among the patients, fatigue, anxiety and depression explained 49% of the total variance in self-reported health complaints (p ≤ 0.001).ConclusionMost women with breast cancer (76%) reported health complaints equal to the healthy controls. Fatigue, anxiety and depression, not oncological treatments, were significant predictors for the complaints.
