Preliminary study on the association between lignan metabolites and CT non-destructive testing of coconut fruit at different developmental stages.

Lignans play a crucial role in maintaining plant growth, development, metabolism and stress resistance. Computed tomography (CT) imaging technology can be used to explore the internal structure and morphology of plants, and understanding the correlation between the two is highly significant. In this study, the content of lignan metabolites in coconut water was determined using liquid chromatography. The internal structure data of coconut fruit was obtained by CT scanning, and the relationship between lignan metabolites and CT image data at different developmental stages was evaluated using partial least square (PLS) regression. The results showed that the total lignan content in coconut water initially decreased, then increased, and gradually decreased after the maturity stage. The Wenye No. 5 variety exhibited higher levels of Epiturinol, Turbinol, Isobarinin-9'-o-glucoside, 5'-methoxy-rohanoside, Rohan rosin-4,4'-di-o-glucoside, turbinol-4-O-glucoside, cycloisoperinolin-4-O-glucoside compared to local coconuts. Coconut meat had the greatest effect on Rohan rosin-4,4'-di-o-glucoside, coconut water on Daphne, and coconut shell and coconut fiber on Larinin-4'-o-glucoside. The data from different parts of coconut fruit's images showed a significant correlation with the content of lignan metabolites. This study has preliminarily explored the correlation between non-destructive testing of coconut fruit and its development process of coconut fruit, providing a new approach and method for further research on non-destructive testing of coconut fruit development.

An in-depth study of anthocyanin synthesis in the exocarp of virescens and nigrescens oil palm: metabolomic and transcriptomic analysis.

BACKGROUND: Oil palm (Elaeis guineensis Jacq.) is a very important tropical woody oil plant with high commercial and ornamental value. The exocarp of the oil palm fruit is rich in anthocyanosides and proanthocyanidins, which not only give it a bright colour, but also mark the maturity of the fruit. The study of the dynamic change pattern of anthocyanoside content and important anthocyanoside metabolism-related regulatory genes during oil palm ripening is conducive to the improvement of the ornamental value of oil palm and the determination of the optimal harvesting period of the fruits. METHODS: We analyzed the virescens oil palm (AS) and nigrescens oil palm (AT) at 95 days (AS1, AT1), 125 days (AS2, AT2) and 185 days (AS3, AT3) after pollination were used as experimental materials for determining the changes in the total amount of anthocyanins as well as their metabolomics and transcriptomics studies by using the LC-MS/MS technique and RNA-Seq technique. RESULT: The results showed that the total anthocyanin content decreased significantly from AS1 (119 µg/g) to AS3 (23 µg/g), and from AT1 (1302 µg/g) to AT3 (170 µg/g), indicating a clear decreasing trend during fruit development. Among them, the higher flavonoids in AS and AT included anthocyanins such as peonidin-3-O-rutinoside (H35), pelargonidin-3-O-rutinoside (H21), and cyanidin-3-O-glucoside (H7), as well as condensed tannins such as procyanidin B2 (H47), procyanidin C1 (H49), and procyanidin B3 (H48). Notably, nine genes involved in the anthocyanin biosynthetic pathway exhibited up-regulated expression during the pre-development stage of oil palm fruits, particularly during the AS1 and AT1 periods. These genes include: Chalcone synthase (CHS; LOC105036364); Flavanone 3-hydroxylase (F3H; LOC105054663); Dihydroflavonol 4-reductase (DFR; LOC105040724, LOC105048473); Anthocyanidin synthase (ANS; LOC105035842), UDP-glucose: flavonoid 3-O-glucosyltransferase (UFGT; LOC105039612); Flavonoid 3',5'-hydroxylase (F3'5'H; LOC105036086, LOC105044124, LOC105045493). In contrast, five genes demonstrated up-regulated expression as the fruits developed, specifically during the AS3 and AT3 periods. These genes include: Chalcone synthase (CHS; LOC105036921, LOC105035716); Chalcone isomerase (CHI; LOC105045978); UDP-glucose: flavonoid 3-O-glucosyltransferase (UFGT; LOC105046326); Flavonoid 3'-hydroxylase (F3'H; LOC105036086). CONCLUSION: Most of differentially expressed genes exhibited up-regulation during the early stages of fruit development, which may contribute to the elevated anthocyanin content observed in oil palm fruits of both types during the pre-developmental period. Furthermore, the expression levels of most genes were found to be higher in the AT fruit type compared to the AS fruit type, suggesting that the differential expression of these genes may be a key factor underlying the differences in anthocyanoside production in the exocarp of oil palm fruits from these two fruit types. The findings of this study provide a theoretical foundation for the identification and characterization of genes involved in anthocyanin synthesis in oil palm fruits, as well as the development of novel variations using molecular biology approaches.

Unveiling the Secrets of Oil Palm Genetics: A Look into Omics Research.

Oil palm is a versatile oil crop with numerous applications. Significant progress has been made in applying histological techniques in oil palm research in recent years. Whole genome sequencing of oil palm has been carried out to explain the function and structure of the order genome, facilitating the development of molecular markers and the construction of genetic maps, which are crucial for studying important traits and genetic resources in oil palm. Transcriptomics provides a powerful tool for studying various aspects of plant biology, including abiotic and biotic stresses, fatty acid composition and accumulation, and sexual reproduction, while proteomics and metabolomics provide opportunities to study lipid synthesis and stress responses, regulate fatty acid composition based on different gene and metabolite levels, elucidate the physiological mechanisms in response to abiotic stresses, and explain intriguing biological processes in oil palm. This paper summarizes the current status of oil palm research from a multi-omics perspective and hopes to provide a reference for further in-depth research on oil palm.

Tenfold Increase: Acute Pediatric Mastoiditis Before, During, and After COVID-19 Restrictions.

INTRODUCTION: Acute mastoiditis (AM) is a relatively rare complication arising from acute otitis media, a common condition among children. The COVID-19 pandemic has significantly impacted AM cases. We noted a surge in pediatric AM cases in Germany after COVID-19 restrictions were lifted in 2022. This study assesses AM incidence and the clinical course in children before, during, and after the pandemic. The study also explores complication rates and microbial changes. METHODS: Participants: We included children (0-18 yr) diagnosed with AM who underwent mastoidectomy at a tertiary-care university hospital from January 2012 to June 2023.Objectives: We aimed to evaluate AM incidence during pre-COVID, COVID, and post-COVID periods; assess complications; and analyze the microbial spectrum.Data Analysis: Incidence and complication rates were compared between periods, along with the microbial spectrum. RESULTS: Population: 75 children were included (median age, 3.3 yr).Incidence: Significant increases in AM cases occurred in the post-COVID period compared to pre-COVID and COVID periods. No significant difference was observed between pre-COVID and COVID periods.Complications: Complication rates increased notably in the post-COVID period compared to pre-COVID and COVID periods with respect to more sensitive imaging methods being used in the post-COVID period. No significant difference was observed between pre-COVID and COVID periods.Spectrum of Pathogens: No significant differences were found in pathogen distribution between periods. Streptococcus pyogenes and Streptococcus pneumoniae were common throughout. DISCUSSION: The study highlights a substantial rise in AM cases and complications after COVID-19 restrictions were lifted in Germany. This underscores the importance of monitoring infectious diseases and their complications during health crises. Additionally, the study highlights the importance of contrast-enhanced imaging. Further research is needed to explore the mechanisms behind this trend. CONCLUSION: The study reveals a significant increase in pediatric AM cases and complications following the COVID-19 pandemic in Germany. Adequate computed tomographic or magnetic resonance imaging, including contrast enhancement, is shown to be a very important parameter beside clinical symptoms in deciding for the right therapy. Thus, surgical treatment became more important. Continuous monitoring and adaptive healthcare strategies during health crises are vital for optimal patient care. Further research is warranted to understand the reasons behind these trends and to inform future pandemic preparedness efforts.

Multi-Omics Approaches in Oil Palm Research: A Comprehensive Review of Metabolomics, Proteomics, and Transcriptomics Based on Low-Temperature Stress.

Oil palm (Elaeis guineensis Jacq.) is a typical tropical oil crop with a temperature of 26-28 °C, providing approximately 35% of the total world's vegetable oil. Growth and productivity are significantly affected by low-temperature stress, resulting in inhibited growth and substantial yield losses. To comprehend the intricate molecular mechanisms underlying the response and acclimation of oil palm under low-temperature stress, multi-omics approaches, including metabolomics, proteomics, and transcriptomics, have emerged as powerful tools. This comprehensive review aims to provide an in-depth analysis of recent advancements in multi-omics studies on oil palm under low-temperature stress, including the key findings from omics-based research, highlighting changes in metabolite profiles, protein expression, and gene transcription, as well as including the potential of integrating multi-omics data to reveal novel insights into the molecular networks and regulatory pathways involved in the response to low-temperature stress. This review also emphasizes the challenges and prospects of multi-omics approaches in oil palm research, providing a roadmap for future investigations. Overall, a better understanding of the molecular basis of the response of oil palm to low-temperature stress will facilitate the development of effective breeding and biotechnological strategies to improve the crop's resilience and productivity in changing climate scenarios.

Exploring the Potential Impact of GLP-1 Receptor Agonists on Substance Use, Compulsive Behavior, and Libido: Insights from Social Media Using a Mixed-Methods Approach.

Glucagon-like peptide-1 (GLP-1) is involved in a range of central and peripheral pathways related to appetitive behavior. Hence, this study explored the effects of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) on substance and behavioral addictions, including alcohol, caffeine, nicotine, cannabis, psychostimulants, compulsive shopping, and sex drive/libido. Data were collected from various social platforms. Keywords related to GLP-1 RAs and substance/behavioral addiction were used to extract relevant comments. The study employed a mixed-methods approach to analyze online discussions posted from December 2019 to June 2023 and collected using a specialized web application. Reddit entries were the focus here due to limited data from other platforms, such as TikTok and YouTube. A total of 5859 threads and related comments were extracted from six subreddits, which included threads about GLP-1 RAs drugs and associated brand names. To obtain relevant posts, keywords related to potential substance use and compulsive behavior were selected. Further analysis involved two main steps: (1) manually coding posts based on users' references to the potential impact of GLP-1 RAs on substance use and non-substance habits, excluding irrelevant or unclear comments; (2) performing a thematic analysis on the dataset of keywords, using AI-assisted techniques followed by the manual revision of the generated themes. Second, a thematic analysis was performed on the keyword-related dataset, using AI-assisted techniques followed by the manual revision of the generated themes. In total, 29.75% of alcohol-related; 22.22% of caffeine-related; and 23.08% of nicotine-related comments clearly stated a cessation of the intake of these substances following the start of GLP-1 RAs prescription. Conversely, mixed results were found for cannabis intake, and only limited, anecdotal data were made available for cocaine, entactogens, and dissociative drugs' misuse. Regarding behavioral addictions, 21.35% of comments reported a compulsive shopping interruption, whilst the sexual drive/libido elements reportedly increased in several users. The current mixed-methods approach appeared to be a useful tool in gaining insight into complex topics such as the effects of GLP-1 RAs on substance and non-substance addiction-related disorders; some GLP-1 RA-related mental health benefits could also be inferred from here. Overall, it appeared that GLP-1 RAs may show the potential to target both substance craving and maladaptive/addictive behaviors, although further empirical research is needed.

Comparison between propofol and total inhalational anaesthesia on cardiovascular outcomes following on-pump cardiac surgery in higher-risk patients: a randomised controlled pilot and feasibility study.

OBJECTIVES: Myocardial revascularisation and cardiopulmonary bypass (CPB) can cause ischaemia-reperfusion injury, leading to myocardial and other end-organ damage. Volatile anaesthetics protect the myocardium in experimental studies. However, there is uncertainty about whether this translates into clinical benefits because of the coadministration of propofol and its detrimental effects, restricting myocardial protective processes. METHODS: In this single-blinded, parallel-group randomised controlled feasibility trial, higher-risk patients undergoing elective coronary artery bypass graft (CABG) surgery with an additive European System for Cardiac Operative Risk Evaluation ≥5 were randomised to receive either propofol or total inhalational anaesthesia as single agents for maintenance of anaesthesia. The primary outcome was the feasibility of recruiting and randomising 50 patients across two cardiac surgical centres, and secondary outcomes included the feasibility of collecting the planned perioperative data, clinically relevant outcomes and assessments of effective patient identification, screening and recruitment. RESULTS: All 50 patients were recruited within 11 months in two centres, allowing for a 13-month hiatus in recruitment due to the COVID-19 pandemic. Overall, 50/108 (46%) of eligible patients were recruited. One patient withdrew before surgery and one patient did not undergo surgery. All but one completed in-hospital and 30-day follow-up. CONCLUSIONS: It is feasible to recruit and randomise higher-risk patients undergoing CABG surgery to a study comparing total inhalational and propofol anaesthesia in a timely manner and with high acceptance and completion rates. TRIAL REGISTRATION NUMBER: NCT04039854.

New trends of drug abuse in custodial settings: A systematic review on the misuse of over-the-counter drugs, prescription-only-medications, and new psychoactive substances.

The article presents a systematic literature review on the use and the psychiatric implications of over-the-counter drugs (OTC), prescription-only-medications (POM), and new psychoactive substances (NPS) within custodial settings. The searches wer carried out on 2 November 2022 on PubMed, Scopus, and Web of Science in line with PRISMA guidelines. A total of 538 records were identified, of which 37 met the inclusion criteria. Findings showed the most prevalent NPS and OTC and POM classes reported in prisons were synthetic cannabinoids receptor agonists (SCRAs) and opioids, respectively. NPS markets were shown to be in constant evolution following the pace of legislations aimed to reduce their spread. The use of such substances heavily impacts the conditions and rehabilitation of persons in custody, with consequent physical and mental health risks. It is important to raise awareness of the use and misuse of such substances in prisons (i) from an early warning perspective for law enforcement and policy makers (ii) to prompt doctors to cautiously prescribe substances that may be misused (iii) to improve and increase access to treatment provided (iv) to add such substances to routine toxicological screening procedures (v) to improve harm reduction programmes.

Comparison of Two Measurement Paradigms to Determine Electrically Evoked Cochlear Nerve Responses and Their Correlation to Cochlear Nerve Cross-section in Infants and Young Children With Cochlear Implant.

INTRODUCTION: Electrically evoked compound action potentials (ECAPs) are used for intra-/postoperative monitoring with intracochlear stimulation of cochlear implants. ECAPs are recorded in MED-EL (Innsbruck, Austria) implants using auditory response telemetry (ART), which has been further developed with automatic threshold determination as AutoART. The success of an ECAP measurement also depends on the number of available spiral ganglion cells and the bipolar neurons of the cochlear nerve (CN). It is assumed that a higher population of spiral ganglion cell implies a larger CN cross-sectional area (CSA), which consequently affects ECAP measurements. METHODS: Intraoperative ECAP measurements from 19 implanted ears of children aged 8 to 18 months were retrospectively evaluated. A comparison and correlation of ART/AutoART ECAP thresholds/slopes at electrodes E2 (apical), E6 (medial), E10 (basal), and averaged E1 to E12 with CN CSA on magnetic resonance imaging was performed. RESULTS: A Pearson correlation of the ART/AutoART ECAP thresholds/slopes for E2/E6/E10 and the averaged electrodes E1 to E12 showed a significant correlation. The CN CSA did not correlate significantly with the averaged ART/AutoART ECAP thresholds/slopes across all 12 electrodes. SUMMARY: AutoART provides reliable measurements and is therefore a suitable alternative to ART. No significant influence of CN CSA on ECAP thresholds/slopes was observed. A predictive evaluation of the success of ECAP measurements based on CN CSA for a clinical setting cannot be made according to the present data.

Catalase (CAT) Gene Family in Oil Palm (Elaeis guineensis Jacq.): Genome-Wide Identification, Analysis, and Expression Profile in Response to Abiotic Stress.

Catalases (CATs) play crucial roles in scavenging H2O2 from reactive oxygen species, controlling the growth and development of plants. So far, genome-wide identification and characterization of CAT genes in oil palm have not been reported. In the present study, five EgCAT genes were obtained through a genome-wide identification approach. Phylogenetic analysis divided them into two subfamilies, with closer genes sharing similar structures. Gene structure and conserved motif analysis demonstrated the conserved nature of intron/exon organization and motifs among the EgCAT genes. Several cis-acting elements related to hormone, stress, and defense responses were identified in the promoter regions of EgCATs. Tissue-specific expression of EgCAT genes in five different tissues of oil palm was also revealed by heatmap analysis using the available transcriptome data. Stress-responsive expression analysis showed that five EgCAT genes were significantly expressed under cold, drought, and salinity stress conditions. Collectively, this study provided valuable information on the oil palm CAT gene family and the validated EgCAT genes can be used as potential candidates for improving abiotic stress tolerance in oil palm and other related crops.

Metabonomics and Transcriptomic Analysis of Free Fatty Acid Synthesis in Seedless and Tenera Oil Palm.

Oil palm, a tropical woody oil crop, is widely used in food, cosmetics, and pharmaceuticals due to its high production efficiency and economic value. Palm oil is rich in free fatty acids, polyphenols, vitamin E, and other nutrients, which are beneficial for human health when consumed appropriately. Therefore, investigating the dynamic changes in free fatty acid content at different stages of development and hypothesizing the influence of regulatory genes on free fatty acid metabolism is crucial for improving palm oil quality and accelerating industry growth. LC-MS/MS is used to analyze the composition and content of free fatty acids in the flesh after 95 days (MS1 and MT1), 125 days (MS2 and MT2), and 185 days (MS3 and MT3) of Seedless (MS) and Tenera (MT) oil palm species fruit pollination. RNA-Seq was used to analyze the expression of genes regulating free fatty acid synthesis and accumulation, with differences in genes and metabolites mapped to the KEGG pathway map using the KEGG (Kyoto encyclopedia of genes and genomes) enrichment analysis method. A metabolomics study identified 17 types of saturated and 13 types of unsaturated free fatty acids during the development of MS and MT. Transcriptomic research revealed that 10,804 significantly different expression genes were acquired in the set differential gene threshold between MS and MT. The results showed that FabB was positively correlated with the contents of three main free fatty acids (stearic acid, myristate acid, and palmitic acid) and negatively correlated with the contents of free palmitic acid in the flesh of MS and MT. ACSL and FATB were positively correlated with the contents of three main free fatty acids and negatively correlated with free myristate acid. The study reveals that the expression of key enzyme genes, FabB and FabF, may improve the synthesis of free myristate in oil palm flesh, while FabF, ACSL, and FATB genes may facilitate the production of free palmitoleic acid. These genes may also promote the synthesis of free stearic acid and palmitoleic acid in oil palm flesh. However, the FabB gene may inhibit stearic acid synthesis, while ACSL and FATB genes may hinder myristate acid production. This study provides a theoretical basis for improving palm oil quality.

ART and AutoART ECAP measurements and cochlear nerve anatomy as predictors in adult cochlear implant recipients.

PURPOSE: The purpose of this retrospective study is to compare the results of electrically evoked compound action potential (ECAP) measurements using automatic auditory response telemetry (AutoART) with those obtained by ART in adults. The study also aimed to evaluate the predictive value of intraoperative ART and AutoART ECAPs for speech intelligibility (SI) and hearing success (HS), and to determine if cochlear nerve (CN) cross-sectional area (CSA) obtained preoperatively by magnetic resonance imaging (MRI) scans could predict ART and AutoART ECAPs and SI and HS outcome. METHODS: The study analyzed and correlated ART and AutoART ECAP thresholds at electrodes E2, E6, and E10, as well as averaged ECAP thresholds over electrodes E1-E12, using data from 32 implants. Correlations were also examined for ART and AutoART ECAP slopes. In addition, averaged ART and AutoART ECAP thresholds and slopes over all 12 electrodes for each participant were correlated with CN CSA measured from MRI sequences. SI of the monosyllabic Freiburg Speech Test at 65 dB sound pressure level was examined along with averaged ART and AutoART thresholds and slopes over all 12 electrodes. A parallel analysis was performed for HS, derived from the difference between baseline and 6-month SI. Finally, correlations between CN CSA and SI, as well as CN CSA and HS were examined. RESULTS: The results of the study showed a significant positive correlation between ART and AutoART ECAP thresholds and as well as slopes for E2, E6, E10 and averaged thresholds and slopes of E1-E12. However, no significant correlation was observed between ART and AutoART averaged ECAP thresholds and slopes and either SI and HS or CN CSA. Furthermore, no significant correlation was found between CN CSA and SI and HS. CONCLUSION: While AutoART is a reliable and safe program for measuring ECAPs in adults, the study found no preoperative prognostic information on intraoperative ECAP results using parameters extracted from current MRI sequences or pre-/intraoperative information on subsequent hearing outcome using ECAP and CN CSA.

Comparison of speech perception in bimodal cochlear implant patients with respect to the cochlear coverage.

BACKGROUND: The hearing success of patients with bimodal fitting, utilizing both a cochlear implant (CI) and a hearing aid (HA), varies considerably: While some patients benefit from bimodal CI and HA, others do not. OBJECTIVES: This retrospective study aimed to investigate speech perception in bimodally fitted patients and compare it with the cochlear coverage (CC). METHODS: The CC was calculated with the OTOPLAN software, measuring the cochlear duct length on temporal bone CT scans of 39 patients retrospectively. The patients were categorized into two groups: CC ≤ 65% (CC500) and CC > 65% (CC600). Monaural speech intelligibility for monosyllables at a sound pressure level (SPL) of 65 dB in a free-field setting was assessed before and after CI at various time points. The two groups, one with preoperative HA and one with postoperative CI, were compared. Additionally, speech intelligibility was correlated with CC in the entire cohort before CI and at the last available follow-up (last observation time, LOT). RESULTS: Overall, there was no significant difference in speech intelligibility between CC500 and CC600 patients, with both groups demonstrating a consistent improvement after implantation. While CC600 patients tended to exhibit earlier improvement in speech intelligibility, CC500 patients showed a slower initial improvement within the first 3 months but demonstrated a steeper learning curve thereafter. At LOT, the two patient groups converged, with no significant differences in expected speech intelligibility. There was no significant relationship between unimodal/unilateral free-field speech intelligibility and CC. Interestingly, patients with a CC of 70-75% achieved the highest speech intelligibility. CONCLUSION: Despite of the lack of a significant correlation between CC and speech perception, patients appeared to reach their maximum in unimodal/unilateral speech perception primarily at a coverage level of 70-75%. Nevertheless, further investigation is warranted, as CC500 was associated with shorter cochlear duct length, and different types of electrodes were used in both groups.

Significance of endolymphatic sac surgery with and/or without simultaneous cochlea implant surgery in respect of vertigo control and speech perception in patients with Menière's disease.

PURPOSE: The focus on treating patients with Menière's Disease (MD) lies on the reduction of vertigo attacks and the preservation of sensory function. Endolympathic hydrops is considered as an epiphenomenon in MD, which can potentially be altered by endolymphatic sac surgery (ESS). Purpose of the study was to investigate the influences on vertigo control through manipulation of the perilymphatic system with or without ESS. METHODS: Retrospective data analysis of 86 consecutive patients with MD according to current diagnostic criteria after endolymphatic sac surgery alone (ESSalone; n = 45), cochlear implantation (CI) alone (CIalone; n = 12), and ESS with CI (ESS + CI; n = 29), treated at a tertiary referral center. MAIN OUTCOME MEASURES: vertigo control, speech perception pre- and postoperatively. RESULTS: Gender, side, and preoperative treatment were similar in all groups. Age was younger in the ESSalone-group with 56.2 ± 13.0 years (CIalone = 64.2 ± 11.4 years; ESS + CI = 63.1 ± 9.7 years). Definitive MD was present in all the CIalone, in 79.3% of the ESS + CI and in 59.6% of the ESSalone-patients. Likewise, vertigo control rate was 100% in the CIalone, 89.7% in the ESS + CI and 66.0% in the ESSalone-group. CONCLUSIONS: Vertigo control was improved in all three groups, however, superior in groups treated with CI, potentially contributed by the manipulation of both the endo- and perilymphatic systems. A more systematic characterization of the patients with larger case numbers and documentation of follow up data would be needed to evaluate a clinical effect more properly.

Long-term results and quality of life after vibrant soundbridge implantation (VSBs) in children and adults with aural atresia.

PURPOSE: The aim of this study was to evaluate the long-term effectiveness and acceptance of the active middle ear implant system Vibrant Soundbridge (VSB®, MED-EL, Austria) in patients with aural atresia or aplasia (children and adults). METHODS: Data from 51 patients (mean age 13.9 ± 11.3 years), 42 (79.2%) children and adolescents, and 11 (20.8%) adults) who received a VSB implant between 2009 and 2019 at the Department of Otolaryngology at LMU Clinic Großhadern, Munich were included in the study. Pure-tone audiometry, speech recognition in a quiet environment and in a noisy environment were performed preoperatively, during the first fitting of the audio processor, after 1-3 years, after 3-5 years, and after 5 years (if possible). The follow-up period ranged from 11 to 157 months with a mean of 58.6 months (4.8 years). Furthermore, the benefit of the VSB was evaluated by self-assessment questionnaires (Speech, Spatial, and Qualities of Hearing Scale, respectively, for parents). RESULTS: Significant improvements were observed in hearing and speech comprehension immediately after the initial fitting of the VSB system (mean hearing gain 38.4 ± 9.4 dB HL) and at follow-up intervals (1-3, 3-5 and after 5 years) for children and adults (p < 0.01). The values remained stable over the long-term, indicating a sustained functional gain from the VSB (mean hearing gain 38.9 ± 9.2 dB HL). The results of the self-assessments affirm the positive influence on hearing and speech comprehension with the VSB. With the VSB, there was an improvement of 41.3 ± 13.7% in the Freiburg monosyllable test. CONCLUSION: These results (a stable hearing gain over the long term, a good tolerance of the implant and an improvement in quality of life) affirm the recommendation for using the active middle ear implant VSB as early as permitted for aural atresia and aplasia patients. This study represents the audiometric results with the (to date) largest collective of aural atresia patients and with a long follow-up period.

GLP-1 Receptor Agonists and Related Mental Health Issues; Insights from a Range of Social Media Platforms Using a Mixed-Methods Approach.

The emergence of glucagon-like peptide-1 receptor agonists (GLP-1 RAs; semaglutide and others) now promises effective, non-invasive treatment of obesity for individuals with and without diabetes. Social media platforms' users started promoting semaglutide/Ozempic as a weight-loss treatment, and the associated increase in demand has contributed to an ongoing worldwide shortage of the drug associated with levels of non-prescribed semaglutide intake. Furthermore, recent reports emphasized some GLP-1 RA-associated risks of triggering depression and suicidal thoughts. Consistent with the above, we aimed to assess the possible impact of GLP-1 RAs on mental health as being perceived and discussed in popular open platforms with the help of a mixed-methods approach. Reddit posts yielded 12,136 comments, YouTube videos 14,515, and TikTok videos 17,059, respectively. Out of these posts/entries, most represented matches related to sleep-related issues, including insomnia (n = 620 matches); anxiety (n = 353); depression (n = 204); and mental health issues in general (n = 165). After the initiation of GLP-1 RAs, losing weight was associated with either a marked improvement or, in some cases, a deterioration, in mood; increase/decrease in anxiety/insomnia; and better control of a range of addictive behaviors. The challenges of accessing these medications were a hot topic as well. To the best of our knowledge, this is the first study documenting if and how GLP-1 RAs are perceived as affecting mood, mental health, and behaviors. Establishing a clear cause-and-effect link between metabolic diseases, depression and medications is difficult because of their possible reciprocal relationship, shared underlying mechanisms and individual differences. Further research is needed to better understand the safety profile of these molecules and their putative impact on behavioral and non-behavioral addictions.

Didactic and narrative persuasion: An experiment to promote colorectal cancer screening.

We tested whether a didactic and a narrative video (i.e. educational content and personal stories versus irrelevant information) could boost colorectal cancer (CRC) screening intention directly and through cognitive predictors of CRC screening behavior. We also tested whether exposure to a story changed participants' affective forecasting, reducing the perception of negative emotions associated with CRC screening (disgust, embarrassment, and fear). The study was conducted online with a between-participants design and recruiting a convenience sample (N = 375). We found that, compared with watching the control video, being exposed to the narrative video about CRC screening was indirectly associated with greater screening intention via vicarious experience and positive attitudes, whereas watching the didactic video was positively associated with CRC screening intention only among participants who had received an invitation letter but did not get screened, and among those yet to receive an invitation to screen. In the latter group, screening intention was boosted through positive attitudes. Our findings do not confirm that stories change affective forecasting, but narration likely fosters messages acceptance through vicarious experience. We also found support for the effectiveness of physicians' recommendations in promoting CRC screening, an intervention that might be effectively administered through a generalized, cost-effective video.

Comparing Outcomes After Referral to Physical Therapy for Patients With Glenohumeral Osteoarthritis Based on the Radiographic Osteoarthritis Severity: A Retrospective Analysis.

Introduction Glenohumeral osteoarthritis (GHOA) is a common cause of musculoskeletal pain (MSP) that can frequently lead to pain and functional disability in patients throughout the world. GHOA can be managed with conservative or surgical interventions, although conservative interventions, such as physical therapy (PT), are generally first-line interventions depending on the severity of GHOA. The purpose of this retrospective analysis was to examine how conventional PT impacts outcomes for patients with GHOA based on the severity of radiographic GHOA findings. Methods This study is a retrospective chart review of patients who were referred to PT for MSP and received PT in the outpatient setting between 2016 and 2022. Inclusion criteria were patients who received PT in the outpatient setting, received PT for MSP, had shoulder radiograph imaging within two years of initial PT evaluation, had more than one PT visit (i.e. attended a follow-up session after initial evaluation), and did not have a history of shoulder surgery. Primary outcome measures were pain, abduction active range-of-motion (AROM), and disability via the quick disabilities of the arm, shoulder, and hand (DASH). Patients were divided into the No GHOA group (n=104), Mild GHOA group (n=61), and Moderate/Severe GHOA group (n=55) based on the radiographic GHOA severity. Results All included patients (n=220) had a mean age of 62.2 ± 12.4 years old with a mean number of PT visits of 7.8 ± 4.5 visits. There was initially a significant difference in the magnitude of pain improvement between the three groups based on radiographic severity of GHOA (Kruskal-Wallis H=6.038; p=0.049); however, post hoc testing revealed no significant difference between any of the three groups for pain improvement (p=0.061 to p=1.000). There was also no significant difference in the magnitude of abduction AROM improvement between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=2.887; p=0.236). Finally, there was no significant difference in the magnitude of disability improvement via the Quick DASH between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=0.156; p=0.925). Conclusion Patients with GHOA referred to PT experience small but statistically significant short-term improvements in pain, abduction AROM, and disability regardless of GHOA radiographic severity. There is no significant association between the magnitude of clinical improvement and the severity of radiographic GHOA. However, despite statistically significant improvements in pain, only patients with mild GHOA experienced clinically significant improvements in pain. Patients with GHOA, regardless of severity, may or may not experience clinically significant improvements in disability after PT.

Clinical Outcomes Associated With the Addition of a Physical Therapist Assistant to a Rehabilitation Team When Treating Musculoskeletal Shoulder Pain in the Outpatient Setting: A Retrospective Cohort Study.

Introduction Musculoskeletal shoulder pain (MSP) is a common condition frequently treated in an outpatient setting by a physical therapy rehabilitation team. Treatment teams can consist of physical therapists (PTs) with or without physical therapist assistants (PTAs). It is currently unknown how different physical therapy team compositions can impact patient outcomes in the outpatient setting. The purpose of this study is to examine how the addition of PTAs to a physical therapy treatment team would impact clinical outcomes when treating patients with MSP in the outpatient setting. Methods This study is a retrospective cohort analysis comparing clinical outcomes for pain, active range of motion (AROM), and disability for patients with MSP when treated by physical therapy treatment teams with or without the presence of PTAs. Inclusion criteria were patients treated for MSP in an outpatient physical therapy clinic without a history of shoulder surgery. Depending on the rehabilitation team composition, patients were divided into a PT-only group or a PTA group. Results Total patients (n = 238) had a mean age of 62.6 ± 12.6 years (median: 64 years) with a mean total number of physical therapy visits of 7.8 ± 4.9 visits (median: 7.0 visits). Of the entire cohort, the PT-only group had 100 patients and the PTA group had 138 patients. There was no significant difference in the magnitude of pain improvement (mean: 1.5 versus 1.9 points, p = 0.177), the magnitude of abduction AROM improvement (mean: 17.6 versus 13.9 degrees, p = 0.173), and the magnitude of disability improvement (mean: 18.9 versus 13.4 percentage points, p = 0.221) between the PT-only group and the PTA group. However, the PT-only group had significantly fewer total visits as compared to the PTA group (6.7 versus 8.6 visits, p < 0.001). Conclusion The addition of PTAs to a rehabilitation team when treating patients with MSP in the outpatient setting does not appear to adversely impact pain, AROM, or disability outcomes. However, patients treated only by PTs had significantly less visits with similar outcomes. More research is needed to determine the interplay between cost, healthcare utilization, and patient outcomes to maximize quality care.
