In rod we trust-The evaluation of a virtual rod and frame test as a cybersickness screening instrument.

Although Virtual Reality (VR) holds massive potential, its applicability still faces challenges because some individuals experience cybersickness. This phenomenon includes general discomfort, disorientation, and/or nausea, and it threatens not only a pleasant user experience but also the user's safety. Thus, predicting a user's susceptibility without relying on screening questionnaires that focus on past experiences, would enable more pleasant, safer VR experiences, especially for first-time users. Hence, the current study uses the participant's controller input in a virtual Rod and Frame Test (RFT) as an effortlessly trackable performance measure. The RFT is an established method for measuring an individual's sense of verticality in visually displaced fields. It has been used in the context of simulator sickness and cybersickness. In line with the literature and the subjective vertical mismatch theory, a lower visual dependency is expected to be correlated positively with cybersickness. To evaluate the potential of the RFT as a screening method for cybersickness, a cybersickness-inducing virtual environment (the City) was deployed. In total, data from 76 participants were eligible for the statistical analysis. The study finds a positive correlation between lower visual dependency and cybersickness, but only for the group that took the RFT after experiencing the City and only for the post-RFT cybersickness ratings. As cybersickness symptoms were VR environment-specific, the predictive validity of the RFT considering the VR-specific attributes is limited. Further, other studies attributed different working mechanisms to explain the connection between visual dependence and cybersickness with conflicting evidence. Although the RFT is not applicable as a cybersickness screening method, the effect sizes suggest that the RFT could serve as an additional objective assessment of the individuals' current state during VR exposure. Future research should systematically explore interconnections between the various factors that contribute to cybersickness, pursuing the idea of open science for context sensitivity.

Sounds of Nature and Hearing Loss: A Call to Action.

The ability to monitor surrounding natural sounds and scenes is important for performing many activities in daily life and for overall well-being. Yet, unlike speech, perception of natural sounds and scenes is relatively understudied in relation to hearing loss, despite the documented restorative health effects. We present data from first-time hearing aid users describing "rediscovered" natural sounds they could now perceive with clarity. These data suggest that hearing loss not only diminishes recognition of natural sounds, but also limits people's awareness of the richness of their environment, thus limiting their connection to it. Little is presently known about the extent hearing aids can restore the perception of abundance, clarity, or intensity of natural sounds. Our call to action outlines specific steps to improve the experience of natural sounds and scenes for people with hearing loss-an overlooked aspect of their quality of life.

ChatGPT and me: First-time and experienced users’ perceptions of ChatGPT’s communicative ability as a dialogue partner

Chatbots like ChatGPT have the potential to produce more natural conversational user interface interactions. Yet, we currently know little about perceptions of ChatGPT as a dialogue partner, and if interaction changes these. Through an online, two-stage, mixed methods study conducted in July 2023, in which first-time and experienced users living in the UK or Ireland engaged in tasks with ChatGPT, we show that interaction improves attitudes towards the system for first-time users, while these attitudes are already positive and stable in experienced users. We further show that first-time users’ perceptions of ChatGPT’s communicative ability (competence, human-likeness, and flexibility) are more dynamic than those of experienced users, although the experienced users’ perceptions also peak post-interaction. When reflecting on their interaction experience with ChatGPT, both groups were positive with little mention of limitations. We discuss the implications of these findings for user perceptions of ChatGPT as a dialogue partner, and highlight the potential risks of uncritical adoption of such technology.

Persistence and Adherence to GLP-1 RA treatment in Type 2 Diabetes Mellitus: a Nationwide registry study

Abstract Background The use of glucagon-like peptide-1 receptor agonsists (GLP-1 RA) continues to rise and is increasingly important in the treatment of type-2 diabetes mellitus (T2DM). Though the use of GLP-1 RA continues to increase, persistence and adherence to therapy remains suboptimal. Purpose We aimed to assess the level of adherence and persistence to GLP-1 RA using real-world data and to investigate sociodemographic and clinical factors associated with discontinuation of GLP-1 RA therapy. Methods In this retrospective cohort study, all first-time users of GLP-1 RA with T2DM ≥18 years from 2007-2020 were identified using the Danish registries (Figure 1A-1B). All participants had 18 months of follow-up. Medication possession ratio (MPR) was calculated by summing days of medication supply from all dispensed prescription made during the study period divided by number of days in study period. MPR ≥0.80 was used to define adherence. Discontinuation was defined as >90 days between the last day of prescription coverage and the first day of a new dispensed prescription. Adherence to GLP-1 RA therapy and the risk of discontinuing therapy was estimated at 6- and 12-months of follow-up. Multivariable logistic regression was used to identify sociodemographic and clinical factors associated with discontinuing GLP-1 RA therapy. Results In total, 44,343 first-time users of GLP-1 RA with T2DM were identified (mean age: 58.6 years, 42.7% female, 21.3% had cardiovascular disease, median duration of T2DM was 6.8 years, median HbA1c was 65 mmol/mol). The absolute risk of discontinuing GLP-1 RA at 6 and 12 months was 14.2% (95%CI: 13.9-14.6) and 21.4% (95%CI: 21.1-21.8), respectively (Figure 2A). Of the 9,520 (21.5%) who discontinued therapy during the 12-month follow-up, 1,947 (20.5%) occurred within the first 31 days of treatment. At 6 months, 58.5% were adherent to GLP-1 RA therapy with a median MPR of 0.84 [IQR: 0.70-0.95]. At 12 months, 61.1% were adherent to therapy with a median MPR of 0.85 [IQR: 0.71, 0.94]. In the multivariable model, low (<40 years) and high age (>75 years), lower household income, educational level, longer diabetes duration, and higher comorbidity burden were associated with a higher risk of discontinuing GLP-1 RA whereas baseline HbA1c was not (Figure 2B-2E). Conclusion Approximately one in five patients discontinued therapy within 12 months and a little over 60% were adherent. Sociodemographic factors, including household income, age, and comorbidity burden were associated with risk of discontinuing GLP-1 RA therapy. Given the changing landscape of who should be treated with GLP-1 RA, the cardio-renal benefits reported in recent trials, and the ongoing trials in the field, future research into adherence and persistence to GLP-1 RA and possible interventions to improve these, are needed.

Self-Guided Blood Pressure Screening in the Community, Opportunities, and Challenges.

Community-based health check kiosks provide opportunities to improve the detection and long-term monitoring of hypertension. We describe the sociodemographic and cardiovascular characteristics of first-time and repeat users of these kiosks. This was an observational study. Deidentified data collected from 430 SiSU Health consumer-facing health check stations in pharmacies across Australia between January 2018 and November 2020 were analyzed. Using a logistic regression, we identified factors associated with repeat checks in the overall cohort and in those with possible hypertension presented as adjusted odds ratios (aOR) and 95% CIs. A total of 982 122 unique checks were conducted; 54% (n=530 139) of the health check users were female, and the average age of all users was 38.2 (SD, 16.0) years. Notably, 13% used the kiosks more than once. Overall, 22% met the definition of possible hypertension, 16% (n=136 345) had blood pressure (BP) ≥140/90 mm Hg, 4% (n=34 349) had BP >160/100 mm Hg, and 13% (121 282) reported taking BP medicines. In the adjusted analysis, first-time users who were aged 50 to 69 years (aOR, 0.91 [95% CI, 0.87-0.96]) or ≥70 years (aOR, 0.68 [95% CI, 0.62-0.74]) were less likely than young users (18-29 years) to return for a second health check. Those in very remote areas were 61% (aOR, 0.39 [95% CI, 0.19-0.72]), and smokers were 13% less likely to return (aOR, 0.87 [95% CI, 0.83-0.91]). People taking BP medications were more likely to return (aOR, 1.16 [95% CI, 1.09-1.22]). Community-based health checks may identify people with high BP and could provide an option for self-monitoring. Broader implementation is needed to increase the reach in rural areas and among the elderly population.

Association between food security status and dietary patterns in a cohort of first-time food-aid users.

To examine the associations between food security status and dietary patterns among first-time food-aid users. From September 2018 to January 2020, a sample of 1001 newly registered food-aid users from 106 community-based food donation organizations were recruited across urban, rural, and peri-urban areas in four administrative regions of the province of Quebec, Canada. The Household Food Security Survey Module (HFSSM) and the Short Diet Questionnaire (SDQ) were used to assess food security status and food intake, respectively. A posteriori dietary patterns were identified through principal component analysis. Regression analyses were performed on 987 participants with complete data to quantify the association between food security status and dietary patterns. Three main dietary patterns were identified: prudent (intake of fruits and fruit juice, plant-based beverages and legumes, green salad, carrots, other vegetables, whole grains, and fish), western (intake of poultry, red meat, potatoes and fried potatoes, rice, and pasta and refined grains), and snack foods (intake of salty snacks, cheese, butter and margarine, sweets, condiments, sweet beverages, and processed meat). Food insecurity was negatively associated with the prudent dietary pattern and positively associated with the snackfood dietary pattern. This study highlights the complexity of dietary patterns in a vulnerable population of first-time food-aid users, especially among those who are severely food insecure.

Buprenorphine/Naloxone vs Methadone for the Treatment of Opioid Use Disorder

Previous studies on the comparative effectiveness between buprenorphine and methadone provided limited evidence on differences in treatment effects across key subgroups and were drawn from populations who use primarily heroin or prescription opioids, although fentanyl use is increasing across North America. To assess the risk of treatment discontinuation and mortality among individuals receiving buprenorphine/naloxone vs methadone for the treatment of opioid use disorder. Population-based retrospective cohort study using linked health administrative databases in British Columbia, Canada. The study included treatment recipients between January 1, 2010, and March 17, 2020, who were 18 years or older and not incarcerated, pregnant, or receiving palliative cancer care at initiation. Receipt of buprenorphine/naloxone or methadone among incident (first-time) users and prevalent new users (including first and subsequent treatment attempts). Hazard ratios (HRs) with 95% compatibility (confidence) intervals were estimated for treatment discontinuation (lasting ≥5 days for methadone and ≥6 days for buprenorphine/naloxone) and all-cause mortality within 24 months using discrete-time survival models for comparisons of medications as assigned at initiation regardless of treatment adherence ("initiator") and received according to dosing guidelines (approximating per-protocol analysis). A total of 30 891 incident users (39% receiving buprenorphine/naloxone; 66% male; median age, 33 [25th-75th, 26-43] years) were included in the initiator analysis and 25 614 in the per-protocol analysis. Incident users of buprenorphine/naloxone had a higher risk of treatment discontinuation compared with methadone in initiator analyses (88.8% vs 81.5% discontinued at 24 months; adjusted HR, 1.58 [95% CI, 1.53-1.63]), with limited change in estimates when evaluated at optimal dose in per-protocol analysis (42.1% vs 30.7%; adjusted HR, 1.67 [95% CI, 1.58-1.76]). Per-protocol analyses of mortality while receiving treatment exhibited ambiguous results among incident users (0.08% vs 0.13% mortality at 24 months; adjusted HR, 0.57 [95% CI, 0.24-1.35]) and among prevalent users (0.08% vs 0.09%; adjusted HR, 0.97 [95% CI, 0.54-1.73]). Results were consistent after the introduction of fentanyl and across patient subgroups and sensitivity analyses. Receipt of methadone was associated with a lower risk of treatment discontinuation compared with buprenorphine/naloxone. The risk of mortality while receiving treatment was similar for buprenorphine/naloxone and methadone, although the CI estimate for the hazard ratio was wide.

Club Drugs and Psychiatric Outcomes: A Descriptive Case Series from Spain

Background: illegal drugs significantly contribute to global health issues, with health complications often occurring not only in regular users with Substance Use Disorders (SUDs) but also in first-time and occasional users. Methods: this study examines five clinical cases from a public hospital in Ibiza, Spain, where patients presented with acute psychiatric symptoms due to recreational drug use. Results: Contrary to previous studies on SUDs, our patients typically had higher education levels and stable employment. Most of them used multiple substances, with cannabis, cocaine, and alcohol being the most frequently used. There was also a common occurrence of consuming drugs with uncertain contents. Upon admission, typical symptoms included aggression, hallucinations, mood swings, and disorientation in time and space. Conclusions: Our findings underscore the significant mental health risks posed by illicit drugs, even for individuals with no prior psychiatric history. Factors like the drug’s potency, frequency and amount of use, past mental health issues, personality traits, and previous traumatic experiences might influence the onset of these symptoms.

SQuID (subcutaneous insulin in diabetic ketoacidosis): Clinician acceptability.

We previously implemented the SQuID protocol (subcutaneous insulin in diabetic ketoacidosis [DKA]) demonstrating safe, effective treatment of low- to moderate-severity DKA in a non-intensive care unit setting. Since success and sustainability of interventions rely on staff buy-in, we assessed acceptability of SQuID among emergency department (ED) and inpatient clinicians. We conducted a cross-sectional study in an urban academic hospital (March 2023-November 2023), surveying ED nurses (RNs) and physicians (MDs) and floor RNs and MDs treating patients on SQuID via emailed survey links. Clinicians could only take the survey once. We used Sekhon's Theoretical Framework of Acceptability, validated for staff acceptability of a new intervention, assessing eight domains with 5-point Likert responses. Clinicians were asked about prior experience with SQuID, and we assessed ED MD and RN preference (SQuID vs. intravenous [IV] insulin). Surveys included free-text boxes for comments. We present descriptive statistics including proportions with 95% confidence interval and medians with interquartile ranges (IQRs) and conducted thematic analysis of free-text comments. Our overall response rate (107/133) was 80% (34/42 ED RNs, 13/16 floor RNs, 47/57 ED MDs, 13/17 floor MDs), with first-time users of SQuID ranging from 7.7% (hospitalist MDs) to 35.3% (ED RNs) of participants. ED clinicians preferred SQuID over IV insulin (67% vs. 12%, 21% no preference). Acceptability was high across all domains and clinician types (median 4, IQR 4-5). Overall percentage of positive responses (4s and 5s) across domains was 92% (ED RNs [89%], floor RNs [89%], ED MDs [97%], floor MDs [87%]). We identified several themes among participant comments. Acceptability was high across clinician types; 65% of ED clinicians preferred SQuID to IV insulin. Clinicians liked SQuID (affective attitude), found it easy to use (burden), were confident in its use (self-efficacy), felt that it improved outcomes (perceived effectiveness), found that it was fair to patients (ethicality), found that it made sense (intervention coherence), and found that it did not interfere with other activities (opportunity cost).

Randomised Controlled Trial for the Evaluation of the Efficacy of the IDA's "Living Well" Online Counselling Tool in First-Time Adult Users with Hearing Loss.

Effective management of hearing loss through the use of modern hearing aids significantly improves communication and the quality of life for individuals experiencing auditory impairment. Complementary counselling of patients with hearing loss who will be fitted with hearing aids for the first time should be evidence-based and adapted to their individual needs. To date, several counselling protocols and tools have been developed. The aim of this randomised controlled trial study was to investigate the efficacy of the application of the IDA's "Living Well" counselling tool in first-time hearing aid users in terms of the degree of their hearing related handicap (using the Hearing Handicap Inventory (HHI)), their communication coping strategies (using the Communication Profile for the Hearing Impaired (CPHI)) and their overall satisfaction of the hearing aids (using a Likert scale). Both groups (the IDA and the control group) were fitted with hearing aids and received counselling for their hearing aids by the same audiologist. The IDA group attended an additional counselling session about communication coping strategies with the use of the "Living Well" tool. Both groups' participants were seen for their hearing aid fittings 4-6 weeks, 3 and 6 months after their fitting when the HHI and the CPHI were measured. Although there was not a statistically significant difference between the two groups for the primary and secondary outcomes, the IDA group did show a more consistent improvement of their HHI score and less frequent use of maladaptive strategies. The "Living Well" counselling tool proved to be a favourably received and helpful counselling tool in first-time hearing aid users.

User engagement with home blood pressure monitoring: a multinational cohort using real-world data collected with a connected device.

Connected blood pressure (BP) monitors provide reliable data when used properly. Our objective was to analyse the engagement of real-world users with self-measurements. We included adult first-time users of a connected BP monitor from July 2019 to March 2021. They were categorized as persistent users if they continued to use the device between 311 and 400 days after inclusion. We defined a criterion to analyse the timing of self-measurements: at least 12 measurements performed within three consecutive days, at least once every 90 days. Persistent users were clustered by state sequence analysis according to the consistency of their BP monitor measurement timing with this criterion during 1 year of follow-up. Among the 22 177 included users, 11 869 (54%) were persistent during the first year. Their use was consistent with the timing criterion 25% (median) of this time (first and third quartiles: 0%, 50%) and four patterns of use were identified by clustering: 5215 persistent users (44%) only performed occasional sparse measurements, 4054 (34%) complied at the start of follow-up up to eight cumulated months, 1113 (9%) complied at least once during later follow-up up to eight cumulated months, and the remaining 1487 (13%) complied nine or more cumulated months of follow-up. Although connected BP monitors can collect a high volume of data, the real-life timing of self-measurements is far from recommended schedules. We must promote the use of BP monitors as recommended by guidelines and/or learn to analyse more occasional and sparse measurements.

Online Base Transportation Service Quality and Customers Satisfaction Analysis

This study investigates how customer satisfaction is influenced by various service quality factors, including price, convenience, safety, and information and communication technologies (ICT). The study focused on Go-Jek users in Airmadidi and its surrounding areas, encompassing both frequent and first-time users. Data were collected using a Google Forms questionnaire from a sample of 315 respondents selected through convenience sampling. Prior to distribution, the validity and reliability of the questionnaire were tested with 37 respondents in a pilot study. Pearson correlation coefficients were calculated to assess the relationships between the different service quality attributes (safety, price, convenience, ICT) and customer satisfaction. The results revealed a strong relationship between customer satisfaction and the service quality factors of safety, price, convenience, and ICT. Among these factors, ICT showed the strongest association with customer satisfaction.

Sociodemographics and clinical factors associated with depression treatment outcomes in 65,741 first-time users of selective serotonin reuptake inhibitors: A Danish cohort study in older adults

ObjectiveTo investigate a wide range of sociodemographic and clinical factors associated with treatment outcomes in older adults who initiated an SSRI for depression treatment in a real-world setting. MethodsThis cohort study used Danish registry data covering all older adults (aged ≥65) who initiated SSRIs for depression from 2006 to 2017, first-time (since 1995). We followed the individuals for one year after their SSRI prescription. Six different outcomes were analyzed, including treatment discontinuation, switching, augmentation, psychiatric hospital contacts for depression, psychiatric hospital admission, and suicide attempt/self-harm. Association analyses employed Poisson regression, estimating incidence rate ratios with 95 % confidence intervals. ResultsThe study included 65,741 individuals with a mean age of 78.23 years, and 55.6 % were females. During follow-up, 40.1 % discontinued, 4.8 % switched, 20.3 % received augmentation, 3.0 % had psychiatric hospital contacts for depression, 3.2 % had psychiatric admission, and 0.1 % had suicide attempt/self-harm records. Differential treatment outcomes were observed based on sociodemographic and clinical factors. For example, being female, residing predominantly in rural areas, having psychiatric or somatic diagnoses, and using medications acting on blood/blood-forming organs, the cardiovascular system, or musculo-skeletal systems were linked to fewer unfavorable clinical outcomes. Conversely, marital status as being single or separated and the use of nervous system drugs were associated with a higher risk of unfavorable outcomes. LimitationsConfounding by indication might remain a problem, and depression severity data was not unavailable. ConclusionsOur findings emphasize considering patient characteristics in clinical decisions, as they can influence the clinical course of those undergoing depression treatment.

Adherence to glucagon-like peptide-1 receptor agonist treatment in type 2 diabetes mellitus: A nationwide registry study.

To assess the level of adherence to glucagon-like peptide-1 receptor agonist (GLP-1RA) treatment using real-world data and to investigate the sociodemographic and clinical factors associated with discontinuation of GLP-1RAs. First-time users of GLP-1RAs with type 2 diabetes mellitus (T2DM), aged ≥18 years, in the period 2007 to 2020, were identified using Danish registries, allowing all participants a minimum of 18 months' follow-up. Adherence to GLP-1RA therapy (medication possession ratio >0.80) and discontinuation of GLP-1RA therapy was estimated at 6- and 12-month follow-ups. Multivariable cause-specific Cox regression was used to identify sociodemographic and clinical factors associated with risk of discontinuation. In total, 44 343 first-time users of GLP-1RAs with T2DM were identified (mean age 58.6 years, 42.7% female, median duration of T2DM 6.8 years, median glycated haemoglobin level 65 mmol/mol). The absolute risk of discontinuing GLP-1RA treatment within 6 months was 14.2% (95% confidence interval [CI] 13.9-14.6) and 21.2% (95% CI 20.8-21.5) within 12 months. At 6 months, 50.4% were adherent to GLP-1RA therapy and at 12 months, 48.6% remained adherent. In the multivariable model, younger (<40 years) and older age (>75 years), higher Charlson Comorbidity Index score, lower household income, high school and longer university degree as educational attainment level, and longer diabetes duration were associated with a higher risk of discontinuing GLP-1RA treatment. Approximately one in five patients discontinued GLP-1RA therapy within the first 12 months and only half were adherent. Overall, lower socioeconomic status and higher comorbidity burden were associated with higher risk of discontinuing GLP-1RA treatment.

A NOVEL TRAINING MODEL TO IMPROVE VASCULAR ANASTOMOSIS IN DEEP CAVITY WITH LIMITED ACCESS

Vascular surgery, particularly the anastomosis of blood vessels in deep cavities, poses significant challenges due to limited access and visibility. Traditional dental and surgical education often focuses on superficial techniques, leaving a gap in training for deep cavity procedures. This study introduces a new training model designed to address this gap and enhance skills in vascular surgery. Objective: To improve skills in performing vascular anastomosis in deep cavities, which presents greater difficulty compared to superficial areas, through the use of an improvised training model. Methods: This prospective observational study was conducted at the Combined Military Hospital, Rawalpindi, from 1st September 2023 to 29th February 2024. The improvised training model is box-shaped with a depth akin to the aorta, made of silicone rubber, and features a removable cap for easy cleaning and reuse. The model provides a realistic environment for practicing deep cavity vascular anastomosis. Participants, including experienced and novice surgeons, used the model to assess its effectiveness in enhancing surgical skills. Results: The model was highly effective in improving surgical techniques, with volunteer surgeons reporting an 82.9% enhancement in their skills and experiences. First-time users also noted significant improvements in their surgical competencies. Quantitative analysis showed that the model was perceived as cost-effective (71.4%) and reusable (74.3%). Participants commented on the realism of the model, particularly its depth and complexity, which facilitated repeated practice without the need for animals or cadavers. Conclusion: The study suggests that this improvised training model can significantly enhance skills in vascular anastomosis, particularly in deep cavity situations. The model is affordable, portable, durable, and provides a realistic simulation of aortic anastomosis in restricted spaces. Further studies are needed to validate its efficacy in broader contexts and its impact on patient outcomes.

Analisis Perilaku Memilih Pada Pemilih Pemula Menjelang Pemilu 2024 Melalui Penerapan Konsep Voting Advice Application

The 2024 election moment is an opportunity for voting advice applications (VAA) to help them making wise political choices since it will be filled with many first-time voters. However, the development of VAA in Indonesia requires an understanding of voting behavior in order to be able to provide appropriate advice to users. For this reason, this research aims to determine the voting behavior of first-time voters so that VAA developers will gain a good understanding of the needs of first-time voters in making political choices by distributing national survey and focus group discussion to first-time voters. This research finds that VAA succeeds in presenting willingness to vote, discuss, and act on their first-time voter users, who also have more dominant rational voting behavior despite their low level of knowledge, liking, and urge to vote towards political parties. Corruption eradication, gender,and education issues are the main concerns of first-time voters. Hopefully, the more appropriate VAA works to the issue preferences of first-time voters, the more it will encourage the creation of well-informed choice voters in Indonesia.

Focusing on positive listening experiences improves hearing aid outcomes in first-time hearing aid users: a randomized controlled trial

Objective The objective of this study was to investigate whether positive focus (PF), an intervention that asks hearing aid users to focus on positive listening experiences, improves hearing aid outcomes for first-time hearing aid users. Design The participants were randomised into a control or PF group. They were fitted with hearing aids and followed for six months after fitting. The PF group was asked to report positive listening experiences in their daily life via an app. Participants in both groups were periodically prompted by the app to answer questionnaires about hearing aid satisfaction and benefit. Two follow-up visits at approximately one and six months were performed. Study sample 20 adult first-time hearing aid users in the control and 18 in the PF group. Results Hearing aid satisfaction and benefit scores were significantly better in the PF group, already at two weeks and throughout the six months. In the PF group, the hearing aid outcomes were positively correlated with the number of submitted positive reports. Conclusions These results point to the importance of asking first-time hearing aid users to focus on positive listening experiences and to reflect upon them. This can lead to improved short- and long-term hearing aid outcomes.

Short- and long-term effects of remote synchronous fine-tuning for first-time hearing aid users: a randomised controlled trial

Objective To evaluate the short- and long-term effect of remote synchronous fine-tuning and follow-up visits on hearing-related problems and hearing aid (HA) benefits for first-time HA users. Design A randomised controlled trial. Study sample Patients at public tax-funded HA clinics in Sweden due for aural rehabilitation (AR) were randomised to either an intervention group (n = 33) or a control group (n = 36). Both groups completed the conventional AR process, but the intervention group received synchronous remote fine-tuning of HAs and online follow-up visits. Outcome measures were used before and after intervention, and 6 months and 1 year after intervention. Results Both groups improved hearing-related problems measured with the Hearing Handicap Inventory for the Elderly/Adults over time, and no significant differences were found between the groups. Such improvements were also found for the Abbreviated Profile of Hearing Aid Benefit except for the subscale aversiveness. Both groups decreased the use of HAs in hours/day over time. The intervention group reported significant improvements in activity limitation when measured directly after the intervention, compared to the control group. Conclusion Synchronous remote fine-tuning and follow-ups for first-time HA users did not influence the outcomes of hearing-related problems and HA benefits differently from standard care at our clinic.

Association Between Intrauterine System Hormone Dosage and Depression Risk.

The authors compared the associated risk of incident depression between first-time users of low-, medium-, and high-dose levonorgestrel-releasing intrauterine systems (LNG-IUSs). This national cohort study was based on Danish register data on first-time users of LNG-IUSs, 15-44 years of age, between 2000 and 2022. Cox regression and a G-formula estimator were used to report 1-year average absolute risks, risk differences, and risk ratios of incident depression, defined as initiation of an antidepressant or receipt of a depression diagnosis, standardized for calendar year, age, education level, parental history of mental disorders, endometriosis, menorrhagia, polycystic ovary syndrome, dysmenorrhea, leiomyoma, and postpartum initiation. In total, 149,200 women started using an LNG-IUS, among whom 22,029 started a low-dose one (mean age, 22.9 years [SD=4.5]), 47,712 a medium-dose one (mean age, 25.2 years [SD=6.2]), and 79,459 a high-dose one (mean age, 30.2 years [SD=5.6]). The associated subsequent 1-year adjusted absolute risks of incident depression were 1.21% (95% CI=1.06-1.36), 1.46% (95% CI=1.33-1.59), and 1.84% (95% CI=1.72-1.96), respectively. For the users of high-dose LNG-IUSs, the risk ratios were 1.52 (95% CI=1.30-1.74) and 1.26 (95% CI=1.10-1.41) compared with users of the low- and medium-dose LNG-IUSs, respectively. For users of medium-dose LNG-IUSs, the risk ratio was 1.21 (95% CI=1.03-1.39) compared with users of low-dose LNG-IUSs. First-time use of an LNG-IUS was positively associated with incident depression in an LNG-dose-dependent manner across low-, medium-, and high-dose LNG-IUSs. Although the observational design of the study does not permit causal inference, the dose-response relationship contributes to the body of evidence suggesting a relationship between levonorgestrel exposure and risk of depression.

Client Oriented Scale of Improvement in First-Time and Experienced Hearing Aid Users: An Analysis of Five Predetermined Predictability Categories through Audiometric and Speech Testing.

Objectives: The aim of our investigation was to explore the relationship between unaided pure-tone and speech audiometry and self-reported aided performance measured according to five predetermined COSI categories among first-time hearing aid users and experienced hearing aid users. Methods: Data from 286 patients were retrospectively evaluated. We divided the sample into first-time hearing aid users (G1) and experienced hearing aid users (G2). The correlation between unaided tonal and speech audiometry and five preliminary selected client-oriented scale of improvement (COSI) categories was studied. Results: A greater percentage of hearing aid users aged >80 years and a higher prevalence of severe-to-profound hearing loss in G2 group were observed (p < 0.05). For the total cohort, a mean hearing threshold of 60.37 ± 18.77 db HL emerged in the right ear, and 59.97 ± 18.76 db HL was detected in the left ear (p > 0.05). A significant statistical difference was observed in the group of first-time hearing aid users for the "Television/Radio at normal volume" item, where patients with a lower speech intellection threshold (SIT) were associated with higher COSI scores (p = 0.019). Studying the relationship between the speech reception threshold (SRT) and the COSI item "conversation with 1 or 2 in noise" evidenced worse speech audiometry in patients who scored ≤2 among experienced hearing aid users (p = 0.00012); a higher mean 4-8 kHz frequencies threshold for the better ear was found within the G2 group among those who scored ≤2 in the COSI item "conversation with 1 or 2 in quiet" (p = 0.043). Conclusions: Our study confirms a poor correlation between unaided tonal and speech audiometry and self-reported patient assessment. Although we included only five COSI categories in this study, it is clear that unaided audiometric tests may drive the choice of proper hearing rehabilitation, but their value in predicting the benefit of hearing aids remains limited.
