Nonresponsive Neurons Improve Population Coding of Object Location.

Understanding how heterogeneous neural populations represent sensory input to give rise to behavior remains a central problem in systems neuroscience. Here we investigated how midbrain neurons within the electrosensory system of code for object location in space. In vivo simultaneous recordings were achieved via Neuropixels probes, high-density electrode arrays, with the stimulus positioned at different locations relative to the animal.

Coding of object location by heterogeneous neural populations with spatially dependent correlations in weakly electric fish.

Understanding how neural populations encode sensory stimuli remains a central problem in neuroscience. Here we performed multi-unit recordings from sensory neural populations in the electrosensory system of the weakly electric fish Apteronotus leptorhynchus in response to stimuli located at different positions along the rostro-caudal axis. Our results reveal that the spatial dependence of correlated activity along receptive fields can help mitigate the deleterious effects that these correlations would otherwise have if they were spatially independent.

Can short PROMs support valid factor-based sub-scores? Example of COMQ-12 in chronic otitis media.

Purpose: Interpretable factor solutions for questionnaire instruments are typically taken as justification for use of factor-based sub-scores. They can indeed articulate content and construct validities of a total and components but do not guarantee criterion validity for clinical application. Our previous documentation of basic psychometric characteristics for a 12-item patient-reported outcome measure in adult chronic otitis media (COMQ-12) justified next appraising criterion validity of sub-scores.

Gains in Quality of Life in Chronic Otitis Media Patients After Surgery, Adjusted for Placebo Bias.

Objective: Using a short-form specific questionnaire, we sought to quantify specific and generic benefits of surgery for chronic otitis media (COM) while adjusting for expectancy (placebo) bias.

Study Design: A prospective observational pretreatment/posttreatment study.

Setting: A national tertiary referral center.

COVCOG 2: Cognitive and Memory Deficits in Long COVID: A Second Publication From the COVID and Cognition Study.

COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been often characterized as a respiratory disease. However, it is increasingly being understood as an infection that impacts multiple systems, and many patients report neurological symptoms. Indeed, there is accumulating evidence for neural damage in some individuals, with recent studies suggesting loss of gray matter in multiple regions, particularly in the left hemisphere.

COVCOG 1: Factors Predicting Physical, Neurological and Cognitive Symptoms in Long COVID in a Community Sample. A First Publication From the COVID and Cognition Study.

Since its first emergence in December 2019, coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has evolved into a global pandemic. Whilst often considered a respiratory disease, a large proportion of COVID-19 patients report neurological symptoms, and there is accumulating evidence for neural damage in some individuals, with recent studies suggesting loss of gray matter in multiple regions, particularly in the left hemisphere. There are a number of mechanisms by which COVID-19 infection may lead to neurological symptoms and structural and functional changes in the brain, and it is reasonable to expect that many of these may translate into cognitive problems.

Restricted Eating in Preschoolers with Autism: Mother Stressors and Solutions.

Feeding interventions for children with Autism Spectrum Disorder (ASD) focus solely on the child, not the family milieu. This qualitative study aimed to understand mothers' perspectives on managing restricted eating among preschoolers with ASD. Focus groups were conducted with eleven mothers of preschoolers with ASD.

Feasibility of Attachment-Focused Self-Hypnosis to Change Insecure God Attachment.

Secure God attachment is related to less psychological distress and greater well-being, while insecure God attachment is associated with higher levels of psychological distress and various forms of maladaptive coping. Cognitive resistance may arise, however, when therapists directly address insecure attachment beliefs through overt cognitive-behavioral techniques. Based on principles of the dual process model of cognition, the authors hypothesized that self-hypnosis may be a theoretically sound and feasible treatment to alter insecure attachment, since hypnosis addresses the emotional, experiential cognitive system rather than the analytical, deliberative cognitive system.

Hearing in Adults: A Digital Reprint of the Main Report From the MRC National Study of Hearing.

The 1011-page book, Hearing in Adults, published in 1995, contains the fullest report of the United Kingdom’s Medical Research Council National Study of Hearing. It was designed to determine the prevalence and distribution in Great Britain of audiometrically measured hearing loss as a function of age, gender, occupation, and noise exposure. The study’s size, quality, and breadth made it unique when it was done in the 1980s.

Contrasting Effects of Pressure Compensation on TEOAE and DPOAE in Children With Negative Middle Ear Pressure.

In children with normal cochlear acuity, middle ear fluid often abolishes otoacoustic emissions (OAEs), and negative middle ear pressure (NMEP) reduces them. No convincing evidence of beneficial pressure compensation on distortion product OAE (DPOAE) has yet been presented. Two studies aimed to document effects of NMEP on transient OAE (TEOAE) and DPOAE.

International consensus (ICON) on management of otitis media with effusion in children.

Otitis media with effusion (OME) is a common childhood disease defined as the presence of liquid in the middle ear without signs or symptoms of acute ear infection. Children can be impacted mainly with hearing impairment and/or co-occurring recurrent acute otitis media (AOM) thus requiring treatment. Although many meta-analyses and national guidelines have been issued, management remains difficult to standardize, and use of surgical and medical treatments continue to vary.

Psychometric characteristics of the chronic Otitis media questionnaire 12 (COMQ - 12): stability of factor structure and replicability shown by the Serbian version.

Background: Recently, demand for and supply of short-form patient-reported outcome measures (PROMs) have risen throughout the world healthcare. Our contribution to meeting that demand has been translating and culturally adapting the Chronic Otitis Media Questionnaire-12 (COMQ-12) for adults into Serbian and enhancing its psychometric base on the relatively large Serbian COM caseload. Chronic otitis media can seriously affect quality of life progressively and in long-term, and it remains the major source of hearing problems in the developing world.

The Chronic Otitis Media Benefit Inventory (COMBI): Development and Validation of a Dynamic Quality of Life Questionnaire for Chronic Ear Disease.

Objective: This study introduces a change-oriented short-form health-related quality of life questionnaire suited to symptoms of adult chronic middle ear disease and its consequences, and describes its properties.

Study Design: Two-centre prospective correlational study primarily for instrument development.

Setting: Two otology secondary care centers in England.

Otitis media.

Otitis media (OM) or middle ear inflammation is a spectrum of diseases, including acute otitis media (AOM), otitis media with effusion (OME; 'glue ear') and chronic suppurative otitis media (CSOM). OM is among the most common diseases in young children worldwide. Although OM may resolve spontaneously without complications, it can be associated with hearing loss and life-long sequelae.

Precision-scored parental report questions and HL-scaled tympanometry as informative measures of hearing in otitis media 1: Large-sample evidence on determinants and complementarity to pure-tone audiometry.

Introduction: In otitis media with effusion (OME), hearing loss is a core sign/symptom and basis of concern, with absolute pure-tone threshold sensitivity (in dB HL) by air-conduction providing the default measure of hearing. However several fundamental problems limiting the value of HL measures in otitis media are insufficiently appreciated. To appraise the joint value and implications of multiple hearing measures towards more comprehensive hearing assessment in OM, we examine in two related articles the interrelations and common or diverging determinants of three measures, two of them objective: binaural HL, and ACET (the published quasi-continuous scaling of binaural tympanometry to HL).

Paracingulate sulcus morphology is associated with hallucinations in the human brain.

Hallucinations are common in psychiatric disorders, and are also experienced by many individuals who are not mentally ill. Here, in 153 participants, we investigate brain structural markers that predict the occurrence of hallucinations by comparing patients with schizophrenia who have experienced hallucinations against patients who have not, matched on a number of demographic and clinical variables. Using both newly validated visual classification techniques and automated, data-driven methods, hallucinations were associated with specific brain morphology differences in the paracingulate sulcus, a fold in the medial prefrontal cortex, with a 1 cm reduction in sulcal length increasing the likelihood of hallucinations by 19.

Associations Among Religiousness and Community Volunteerism in National Random Samples of American Adults.

The connection between religiousness and volunteering for the community can be explained through two distinct features of religion. First, religious organizations are social groups that encourage members to help others through planned opportunities. Second, helping others is regarded as an important value for members in religious organizations to uphold.

A causal model for longitudinal randomised trials with time-dependent non-compliance.

In the presence of non-compliance, conventional analysis by intention-to-treat provides an unbiased comparison of treatment policies but typically under-estimates treatment efficacy. With all-or-nothing compliance, efficacy may be specified as the complier-average causal effect (CACE), where compliers are those who receive intervention if and only if randomised to it. We extend the CACE approach to model longitudinal data with time-dependent non-compliance, focusing on the situation in which those randomised to control may receive treatment and allowing treatment effects to vary arbitrarily over time.

Individual differences in behavioral and cardiovascular reactivity to emotive stimuli and their relationship to cognitive flexibility in a primate model of trait anxiety.

High trait anxiety is a risk factor for the development of anxiety disorders. Like the disorders themselves high trait anxiety has marked phenotypic variation at the level of symptomatology and neural circuits, suggesting that there may be different symptoms and distinct neural circuits associated with risk for these disorders. To address these issues, it is essential to develop reliable animal models of trait anxiety in a non-human primate whose brain bears structural and functional similarity to humans.

A new health-related quality of life measure for active chronic otitis media (COMQ-12): development and initial validation.

Objective: To develop and document for clinical use a new HRQoL questionnaire for the assessment of active chronic otitis media.

Study Design: Two-center prospective correlational study.

Setting: Two otology referral centers in England.

Young-age gender differences in mathematics mediated by independent control or uncontrollability.

We studied whether the origins of math anxiety can be related to a biologically supported framework of stress induction: (un)controllability perception, here indicated by self-reported independent efforts in mathematics. Math anxiety was tested in 182 children (8- to 11-year-olds). Latent factor modeling was used to test hypotheses on plausible causal processes and mediations within competing models in quasi-experimental contrasts.

Addiction potential of phentermine prescribed during long-term treatment of obesity.

Objective: To investigate if phentermine treatment induces phentermine abuse, psychological dependence (addiction) or phentermine drug craving in overweight, obese and weight loss maintenance patients. To investigate whether amphetamine-like withdrawal occurs after abrupt cessation of long-term phentermine treatment.

Design: Clinical intervention trial with interruption of phentermine treatment in long-term patients.

Screening for hearing loss versus parental concern regarding hearing problems: Subsequent referral and treatment for otitis media in the Netherlands.

Objective: The present study investigates whether general practitioner (GP) consultation initiated by failing the population hearing screening at age nine months or GP consultation because of parental concern over ear/hearing problems was more important in deciding on referral and/or surgical treatment of otitis media (OM).

Design: A questionnaire covering the history between birth and 21 months of age was used to obtain information on referral after failing the hearing screening, GP consultations for ear/hearing problems, and subsequent referral to a specialist and possible surgical treatment at an ENT department.

Setting: The province of Limburg, the Netherlands.

Impact of pneumococcal conjugate vaccination on otitis media: a systematic review.

Acute otitis media (AOM) is a leading cause of visits to physicians and of antibiotic prescriptions for young children. We systematically reviewed studies on all-cause AOM episodes and physician visits in which impact was attributed to pneumococcal conjugate vaccines, either as efficacy or effectiveness. Of 18 relevant publications found, most used the 7-valent pneumococcal conjugate vaccine (7vCRM).
