Overall, the LEQ-CI21 was found to meet the Rasch model criteria for interval-level measurement. The LEQ-CI21 is the first PROM to be developed specifically for the measurement of perceived listening effort and one of the first patient-reported outcome measures for use with CI patients to be developed using Rasch analysis. The LEQ-CI21 has the potential to be used as a research tool and in clinical practice to evaluate perceived listening effort in daily life. Further psychometric evaluation of the LEQ-CI21 is planned.
The investigation of auditory cognitive processes recently moved from strictly controlled, trial-based paradigms toward the presentation of continuous speech. This also allows the investigation of listening effort on larger time scales (i.e., sustained listening effort). Here, we investigated the modulation of sustained listening effort by a noise reduction algorithm as applied in hearing aids in a listening scenario with noisy continuous speech. The investigated directional noise reduction algorithm mainly suppresses noise from the background.
We recorded the pupil size and the EEG in 22 participants with hearing loss who listened to audio news clips in the presence of background multi-talker babble noise. We estimated how noise reduction (off, on) and signal-to-noise ratio (SNR; +3 dB, +8 dB) affect pupil size and the power in the parietal EEG alpha band (i.e., parietal alpha power) as well as the behavioral performance.
Our results show that noise reduction reduces pupil size, while there was no signe show that the modulation of sustained listening effort (e.g., by hearing aid noise reduction) as indicated by pupil size and parietal alpha power can be studied under more ecologically valid conditions. Mainly concluded from pupil size, we demonstrate that hearing aid noise reduction lowers sustained listening effort. Our study approximates to real-world listening scenarios and evaluates the benefit of the signal processing as can be found in a modern hearing aid.
Hyponatremia is the most common electrolyte disorder in hospitalized patients and occurs in about 30% of patients with pneumonia. Hyponatremia has been associated with a worse outcome in several pathologic conditions The main objective of this study was to determine whether serum sodium alterations may be independent predictors of the outcome of hospitalized COVID-19 patients.
In this observational study, data from 441 laboratory-confirmed COVID-19 patients admitted to a University Hospital were collected. After excluding 61 patients (no serum sodium at admission available, saline solution infusion before sodium assessment, transfer from another hospital), data from 380 patients were analyzed.
274 (72.1%) patients had normonatremia at admission, 87 (22.9%) patients had hyponatremia and 19 (5%) patients had hypernatremia. We found an inverse correlation between serum sodium and IL-6, whereas a direct correlation between serum sodium and PaO2/FiO2 ratio was observed. Patients with hyponatremia had a higher prevalence of non-invasive ventilation and ICU transfer than those with normonatremia or hypernatremia. Hyponatremia was an independent predictor of in-hospital mortality (2.7-fold increase vs normonatremia) and each mEq/L of serum sodium reduction was associated with a 14.4% increased risk of death.
These results suggest that serum sodium at admission may be considered as an early prognostic marker of disease severity in hospitalized COVID-19 patients.

The transcription factor OTX2 is implicated in ocular, craniofacial, and pituitary development.
We aimed to establish the contribution of OTX2 mutations in congenital hypopituitarism patients with/without eye abnormalities, study functional consequences, and establish OTX2 expression in the human brain, with a view to investigate the mechanism of action.
We screened patients from the UK (n = 103), international centres (n = 24), and Brazil (n = 282); 145 were within the septo-optic dysplasia spectrum, and 264 had no eye phenotype. Transactivation ability of OTX2 variants was analysed in murine hypothalamic GT1-7 neurons. In situ hybridization was performed on human embryonic brain sections. Genetically engineered mice were generated with a series of C-terminal OTX2 variants.
Two chromosomal deletions and six haploinsufficient mutations were identified in individuals with eye abnormalities; an affected relative of one patient harboured the same mutation without an ocular phenotype. OTX2 truncations ledc origin.
Patients with acromegaly show musculoskeletal symptoms which may persist despite disease control. Increased i.m. fat fraction is a known cause of muscle dysfunction in several disorders.
To assess the degree of fat fraction in thigh muscles of controlled acromegaly patients and its relationship with muscle dysfunction.
In a cross-sectional study, we included 36 patients with controlled acromegaly and 36 matched controls. We assessed the percentage of fat fraction in each thigh muscle, using MRI 2-point Dixon sequence, and muscle performance and strength using the gait speed, timed up and go, 30-s chair stand, and hand grip strength tests. We evaluated joint symptoms using the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC).
Intramuscular fat fraction was greater in patients than controls (P < 0.05 for muscle compartments, rectus femoris (RF), vastus intermedius (VI), adductor magnus (AM) and semimembranosus). Patients had slower gait speed and poorer performance on the 30-s chair stand and timed up and go tests than controls (P < 0.05). The greater fat fraction in the combined anterior-posterior compartment and in each muscle was associated with worse performance on timed up and go (P < 0.05). The fat fraction in the anterior-posterior compartment predicted performance on timed up and go after adjusting for muscle area, IGF-I and WOMAC functional and pain scores (β = 0.737 P < 0.001).
Patients with controlled acromegaly have greater thigh i.m. fatty infiltration, which is associated with muscle dysfunction. Futures studies are needed to elucidate the mechanisms underlying this relationship.

Increased delay discounting is associated with obesity and binge eating disorder (BED). Although BED and obesity frequently co-occur, the neural mechanisms underlying delay discounting in these conditions remain poorly understood.
Thirtyfive women with obesity, including 10 participants with obesity and BED and 31 controls completed a monetary delay discounting task during functional magnetic resonance imaging.
We identified that increased discounting rates were associated with decreased activity in the left anterior insula in participants with obesity compared to controls when choosing immediate rewards over delayed rewards (PFWE < 0.05). An exploratory analysis comparing the BED subsample to the other groups did not detect significant differences.
Our findings suggest decreased activity in the anterior insula may underlie heightened delay discounting in individuals with obesity, contributing the probability of choosing immediate rewards over delayed rewards based on emotional states. Future studies including larger, more diverse samples are required to confirm these effects.

In our study, we isolated R. peoriensis from an open fracture of the left distal tibia of a three-year-old male patient. Tissue anaerobic culture was positive for R. peoriensis. It was identified with both matrix-assisted laser desorption ionization time-of-flight mass spectrometry and confirmed via 16S rRNA gene sequencing. The patient responded to ampicillin-sulbactam and amikacin antibiotic therapy. Antimicrobial susceptibility testing should be performed to guide the choice of treatment. To the best of our knowledge, this is the first report of R. peoriensis osteomyelitis in a pediatric patient and first report from Turkey.As antimicrobial resistance poses a globally rising health problem, the identification of alternative antimicrobial agents is urgently required. The short chain fatty acid propionate which is physiologically produced by the gut microbiota constitutes a promising molecule given that it has been widely used as a cosmetics and food preservative due to its antimicrobial effects. This literature survey aims to determine the most recent state of knowledge about the antimicrobial and immune-modulatory properties of propionate. GSK-3 signaling pathway Both in vitro and in vivo studies published between 2011 and 2020 confirmed the ability of propionate to inhibit the growth of several cellular pathogens, including Gram-positive and Gram-negative multi-drug resistant bacteria and fungi. In addition, heterogenous immune-modulatory and in particular, anti-inflammatory effects of propionate could be assessed involving a diverse signaling network that needs further comprehension. In conclusion, our literature survey provides evidence that propionate displays a plethora of health-beneficial including antimicrobial and immune-modulatory effects. Future research is required to further unravel the underlying molecular mechanisms and to set the basis for in vivo infection and clinical studies to broaden the path of propionate as a promising adjunct antibiotics-independent option in the combat of infections caused by multi-drug resistant bacteria.
Endometriosis affects approximately 10% of women, with well-documented delays between initial presentation with symptoms and diagnosis. In England, women typically seek help first in primary care, making this setting pivotal in women's pathways to diagnosis and treatment. English General Practitioner (GP) perspectives on managing possible endometriosis have not been previously reported.
To explore what GPs identify as important considerations when caring for women with symptoms that raise the possibility of endometriosis.
English primary care.
Semi-structured scenario-based telephone interviews with 42 GPs based around a fictional scenario of a woman presenting to primary care with symptoms suggesting possible endometriosis. Interviews were thematically coded and analysed.
Managing possible endometriosis in primary care brings challenges. While knowledge and awareness were pre-requisites for considering endometriosis, other important considerations were raised. Symptoms suggestive of endometriosis ant with undifferentiated symptoms, are needed.
Given the prevalence of long-term benzodiazepine (BZD) prescribing, increased monitoring through the implementation of prescription monitoring programmes (PMPs) may be the necessary impetus to promote BZD deprescribing. Despite evidence promoting the importance of patient-centred care, GPs have not been sufficiently supported to implement these principles through current deprescribing practice.
To investigate patients' perception of their prescriber's influence on ceasing BZD use, including their willingness to take their advice, and to understand how a patient's stage of change influences the barriers and facilitators they perceive to discontinuing BZDs.
An online survey and qualitative interviews with 22 long-term users of BZD (≥6 months), aged 18-69 years, recruited from the general population in Victoria, Australia.
Two groups of users of BZD participated, one in the process of reducing their BZD and one not reducing, and were categorised according to their stage of change. Data underwent thematic analysis to identify barriers and facilitators to reducing BZDs both at the patient level and the prescriber level.
