RESUMEN

This study investigates the dynamics of collaborative characteristics, interpersonal reactivity, and disaster situation responses in non-face-to-face settings, a response mechanism increasingly relevant in the wake of prolonged pandemics. By examining a group of 123 university students engaged in a seven-week non-face-to-face collaborative project, the research identifies relational patterns between collaborative traits such as regulation and efficacy, interpersonal empathy, and responses to disaster situations. The research methodology employs a sophisticated analytical framework comprising factor and canonical correlation analyses to identify how empathy and collaborative efficacy significantly related with disaster response in online collaborations. The mediation and moderation models analyzed confirm mutual mediation effects of collaborative regulation and interpersonal reactivity on situational empathy without significant moderation effects. This suggests there were direct causal relationships of collaborative regulation, collaborative efficacy, interpersonal reactivity on situational empathy. The findings underscore the pivotal role of empathy in collaboration during disasters offering a nuanced understanding of the social and psychological underpinnings that enable collective responses to crises in environments lacking physical interaction and illuminating the critical role of collaborative and interpersonal skills in such settings.

RESUMEN

Two novel cyclometalated ruthenium complexes, RC-4 and RC-5, featuring 1-phenylisoquinoline and phenyl quinazoline as ancillary ligands, respectively, were synthesized to investigate their viability with the environmentally friendly copper (Cu) redox mediator, [Cu(bpye)2]2+/+. The modification of the ligand environment resulted in variations in the energetics, photophysical properties, and photovoltaic performance of RC-4 and RC-5 sensitizers. Despite RC-5 sensitizer possessing a more positive ground state potential of 1.19 V versus the NHE, the RC-4 sensitizer, with a lower HOMO level of 0.72 V versus NHE, exhibited superior photovoltaic performance along with the Cu electrolyte, attributed to its enhanced light harvesting ability, improved lifetime and reduced back electron transfer, contributing to higher Jsc, Voc, and PCE.

RESUMEN

BACKGROUND: Changes in oral microbiota composition (dysbiosis) have long been known to play a key role in the pathogenesis of oral and systemic diseases including respiratory diseases. However, till now, no study has assessed changes in oral microbiota following tuberculosis (TB) infection in humans. AIMS: This is the first study of its kind that aimed to investigate oral microbial dysbiosis in newly diagnosed, treatment naïve, TB patients. METHODS: Oral swab samples were collected from newly diagnosed TB patients (n = 20) and age, gender and ethnicity matched healthy controls (n = 10). DNA was extracted and microbiota analyzed by sequencing the hypervariable (V3-V4) region of the bacterial 16S rRNA gene using Illumina MiSeq platform. Bioinformatics and statistical analyses were performed using QIIME and R. RESULTS: Bacterial richness, diversity and community composition were significantly different between TB patients and healthy controls. The two groups also exhibit differential abundance at phylum, class, genus and species levels. LEfSe analysis revealed enrichment (LDA scores (log10) >2, P < 0.05) of Firmicutes (especially Streptococcus) and Actinobacteriota (especially Rothia) in TB patients relative to healthy controls. Gene function prediction analysis showed upregulation of metabolic pathways related to carbohydrates (butanoate, galactose) and fatty acids metabolism, antibiotics biosynthesis, proteosome and immune system signaling. CONCLUSION: These observations suggest significant variations in diversity, relative abundance and functional potential of oral microbiota of TB patients compared to healthy controls thereby suggesting potential role of oral bacterial dysbiosis in TB pathogenesis. However, longitudinal studies using powerful metagenomic and transcriptomic approaches are crucial to more fully understand and confrim these findings.

RESUMEN

STUDY OBJECTIVES: The sleep apnea multi-level surgery (SAMS) randomized clinical trial showed surgery improved outcomes at 6 months compared to ongoing medical management in patients with moderate or severe obstructive sleep apnea (OSA) who failed continuous positive airway pressure therapy. This study reports the long-term outcomes of the multi-level surgery as a case series. METHODS: Surgical participants were reassessed >2 years postoperatively with the same outcomes reported in the main SAMS trial. Primary outcomes were apnea-hypopnea index (AHI) and Epworth sleepiness scale (ESS), with secondary outcomes including other polysomnography measures, symptoms, quality of life, and adverse events. Long-term effectiveness (baseline to long-term follow-up [LTFU]) and interval changes (6 month to LTFU) were assessed using mixed effects regression models. Control participants were also reassessed for rate of subsequent surgery and outcomes. RESULTS: 36/48 (75%) of surgical participants were reevaluated (mean (standard deviation)) 3.5 (1.0) years following surgery, with 29 undergoing polysomnography. AHI was 41/h (23) at preoperative baseline and 21/h (18) at follow-up, representing persistent improvement of -24/h (95% CI -32, -17; p < 0.001). ESS was 12.3 (3.5) at baseline and 5.5 (3.9) at follow-up, representing persistent improvement of -6.8 (95% CI -8.3, -5.4; p < 0.001). Secondary outcomes were improved long term, and adverse events were minor. Interval change analysis suggests stability of outcomes. 36/43 (84%) of the control participants were reevaluated, with 25 (69%) reporting subsequent surgery, with symptom and quality of life improvements. CONCLUSION: Multi-level upper airway surgery improves OSA burden with long-term maintenance of treatment effect in adults with moderate or severe OSA in whom conventional therapy failed. CLINICAL TRIAL: Multi-level airway surgery in patients with moderate-severe obstructive sleep apnea (OSA) who have failed medical management to assess change in OSA events and daytime sleepiness; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=366019&isReview=true; ACTRN12614000338662.

RESUMEN

OBJECTIVES: Dementia care scholarship focuses on care challenges and less on positive aspects of care, especially among culturally and linguistically diverse (CALD) carers outside the United States. This article investigates positive aspects of dementia care across eight CALD groups in Australia. METHODS: We analyzed interviews of 112 family carers using a four-domain framework covering: a sense of personal growth, feelings of mutuality, increases in family cohesion, and a sense of personal accomplishment. RESULTS: Positive associations with care are derived from past relationships, feelings of mutual obligation, valuing changed relationships and enjoying spending time with the person with dementia. Positive aspects of care were not associated with increased family cohesion except in Vietnamese and Arab families; neither was use of ethno-specific residential aged care, except for Greek and Italian families. Religion and spirituality as a coping and comforting mechanism was inconsistently expressed. CONCLUSIONS: The study reveals the multi-dimensional nature of care, what resonates, and diverges across CALD populations. Knowing which parts of the framework apply and which do not is useful for interventions seeking to enhance positive aspects of care. CLINICAL IMPLICATIONS: Migrant populations are varied and dynamic, and practitioners should be mindful of differences within and between ethnic minority groups.

RESUMEN

Objective: To investigate the effect of size, site, and activity of tympanic membrane (TM) perforation on hearing loss (HL) in Aboriginal and Torres Strait Islander (ATSI) children. Design: Observational study. Methodology: Children aged 5-18 years who identified as ATSI at seven Anangu community schools within the Anangu Pitjantjatjara Yankunytjatjara Lands and Maralinga Lands of South Australia underwent 4-frequency pure-tone audiometry (0.5, 1, 2, and 4 kHz) and video-otoscopy (VO). VO data was reviewed by surgeons for a middle ear diagnosis and VO files with TM perforations were then classified by perforation site (AS, AI, PS, PI, A, P, I) and size (<25%, 25%-50%, 50%-75%, or 75%-100%). Results: Five hundred seventy-five VO files with matching audiological data were obtained. Active perforations (35 dBHL; 28-44 IQR) demonstrated greater HL than inactive perforations (31 dBHL; 29-39 IQR) p = .0029. For inactive perforations there was a significant difference between <25% and all larger perforations (p < .0001) whereas for active perforations the significance changed to between <25% (p < .0001) and 25%-50% (p < .05) when compared to larger perforations. When perforation site was compared within all size/activity groups, no statistically different findings were identified. In all analyses, findings did not change when individual frequencies were compared to 4-frequency pure-tone average dBHL. Conclusion: In ATSI children from remote communities, HL is greater in ears with larger perforations and active middle ear disease but there was no relationship between perforation site and HL.Level of evidence: Level 4.

RESUMEN

Introduction: The number of Australian residents with dementia is projected to double by 2058, with 28% currently being migrants from non-Anglophone countries. There will be growing demand for professional interpreters for cognitive assessments and dementia-related health consultations in the future. Interpreting cognitive assessments can be challenging for interpreters; inaccurate interpreting can influence assessment outcomes. The Improving Interpreting for Dementia Assessments (MINDSET) project will upskill interpreters through an online training course in dementia and cognitive assessments. The training has been co-designed with key stakeholders from the interpreting sector, dementia-related services, and family caregivers, and has been user-tested with 12 interpreters. The training aims to improve the quality of interpreter-mediated communication during cognitive assessments, and thereby improve the accuracy and acceptability of cognitive assessments with older people who have limited English proficiency. Methods: We are conducting a single-blinded randomized controlled trial to evaluate the effectiveness of the training. We aim to enroll 150 interpreters, and allocate them to equal parallel groups. The intervention group will receive access to the MINDSET training, which comprises 4 hours of resources covering five domains: dementia knowledge, cross-cultural communication, briefings and debriefings, interpreting skills, and interpreting ethics. The control group will be assigned to a wait list, and will receive access to the training after the trial. Participants will be assessed according to the five domains, via the Dementia Knowledge and Assessment Scale, multiple-choice questions, video-simulated assessments, and ethical scenarios. Assessments will occur at baseline (prior to the intervention group completing the training), 3 months after enrollment, and 6 months after enrollment. Results: The trial is ongoing. Recruitment began in June 2022. Discussion: This is the first time a training resource for interpreters in dementia has been trialed. If successful it may represent a technologically innovative way to offer training to both trainee and practicing interpreters. Highlights: Interpreters are crucial in facilitating cognitive assessments for allophone speakers.Interpreters would benefit from training to improve assessment accuracy.Our study has co-designed specialized dementia training for interpreters.This is a protocol to evaluate the training's efficacy in a randomized controlled trial.

RESUMEN

OBJECTIVES: Tinnitus is a complex and debilitating phenomenon with potentially significant implications on quality of life. New presentations can be resource and time intensive for clinicians. Validated comprehensive tinnitus questionnaires may lack practical utility in the high-volume clinical setting. Concise, targeted questionnaires may offer an efficient alternative. This study aimed to assess the validity of the FiveQ, a novel five question construct designed to measure tinnitus severity. Convergent validity was assessed through correlating FiveQ against two comprehensive validated questionnaires, the Tinnitus Handicap Questionnaire (THQ) and Tinnitus Handicap Inventory (THI). DESIGN: Cross-sectional study with prospective recruitment. The 117 voluntarily recruited participants completed the FiveQ, THI and THQ questionnaires. Results were comparatively analysed. SETTING: Recruitment was via electronic and print media, audiology clinics and public and private otolaryngology outpatient clinics. Surveys were completed electronically. PARTICIPANTS: Members of the public aged over 18 with subjective tinnitus were invited to participate. MAIN OUTCOME MEASURED: Analyses for establishing the content validity, construct validity, internal consistency, explorary factor analysis, and responsiveness of FiveQ was performed. RESULTS: FiveQ demonstrated a high positive correlation with both the THI (r = 0.773, p < .001) and THQ (r = 0.808, p < .001). Internal consistency for FiveQ reached an acceptable threshold (Cronbach's alpha 0.86). Exploratory factor analysis demonstrated that one latent factor underlies the five items of the FiveQ. FiveQ demonstrated better responsiveness than both the THI and THQ after a 6 week interval repeat measurement. CONCLUSION: FiveQ demonstrated high-positive correlations with existing validated tinnitus questionnaires as well as acceptable internal consistency and factor analysis. The concise construct of FiveQ allows clinicians to efficiently estimate tinnitus severity, target treatment towards dominant symptoms and establish a reliable estimation of treatment response following interventions.

RESUMEN

Evidence suggests that family carers of culturally and linguistically diverse (CALD) people living with dementia experience higher stress and unmet need than the general Australian population. These disparities are often framed as the result of CALD communities failing to seek formal support. Challenging this, we draw on the concept of 'structural burden' to explore how the complexity of health and aged systems contribute to the burden that CALD carers experience. We conducted semi-structured interviews with 104 family carers for CALD people with dementia in Australia, followed by thematic analysis of transcripts. Additional to structural burdens encountered by the general older population, CALD carers faced challenges understanding Australia's Anglo-centric aged care system, locating culturally appropriate care and were required to translate the languages and operations of health and aged care systems into terms their family members understood. This burden was mitigated by the presence of ethno-specific organisations and other navigation support. Australia's aged care system has moved towards centralised governance and consumer-directed care provision. This system involves a confusing array of different programmes and levels, bureaucratic applications and long waiting times. Carers' encounters with these systems demonstrates how some CALD people are being left behind by the current aged care system. While ethno-specific services can reduce this burden, not all CALD groups are represented. Consequently, improving access to dementia care among CALD populations requires entry point and navigation support that is culturally appropriate and linguistically accessible.

RESUMEN

The motivation for developing, administering, and participating in full-scale disaster drills is multifold. Emergency drills not only test the capacity of emergency systems but also allow organizations to learn as well as improve processes and communication structures before disasters strike. They have been used as a platform to develop and maintain collaborative networks. This article examines the extent to which organizations collaborate with others during emergency/disaster drills. A social network analysis is employed to determine the patterns of communication and interorganizational networks during the planning and implementation of a full-scale emergency exercise. Specifically, we seek to understand the communication lines that stakeholders used to receive updated information, who they reached out to when standard communication channels were down, and what backup systems were in place. The research was conducted in a municipality located in north central Texas. This study was based on field observations and involved 14 face-to-face interviews with experienced public officials and first responders involved in a municipal government emergency drill/exercise. The interviews were administered after the 2017 full-scale emergency drill. Three major findings can be emphasized from this study. First, two types of organizations, namely, city fire departments and a university partaking in the exercise, played central role as a "bridge" between various organizations during the emergency drill. Second, the types of information considered important during the exercise can be categorized as strategic, procedural, and technical information. Finally, several back-up systems including ham radio, cellphones, internet back-up, and satellite were used to maintain communication channels.

RESUMEN

Drawing on the sociology of emotions, this article investigates the socially and culturally mediated nature of emotions and emotional care within 93 ethnic minority carers' narratives of dementia care. Adding to the cross-cultural literatures on the sociology of emotions and dementia care respectively, our analysis showed that 'signals' of dementia to family carers were often emotional outbursts of anger by the person with dementia. These displays, in turn, created conflict, and aroused emotions such as shame, anger, and depression among carers. To mitigate these tendencies, carers enacted emotional management, which centered on reducing the gravity of negative emotions felt by the person with dementia, and affording them the social space to maintain a positive disposition. To create this positive emotional space, carers deployed different strategies. Some mobilized medical discourses to diffuse the emotional and moral significance of their relative's behavior and enable emotional distantiation. Others conceived of people with dementia as 'childlike' and requiring their protection from emotional negativity. Although, such efforts work took a toll on carers' emotional energies, it was considered enabling, therapeutic, and integral to care. Such emotional work departs from academic and advocacy efforts that see such behavior as patronizing and infantilizing, and underscores the need for more nuanced discussion around emotions and dementia care in ethnic minority families.

RESUMEN

The 'family crisis' narrative is frequently used in dementia studies to explain ethnic minority families' pathways to health and aged care and why there is delayed dementia diagnoses in ethnic minority communities. Such narratives may obscure the family carers' agency in negotiating services and managing personal, social and structural burdens in the lead up to diagnosis. To illuminate agency, this article describes ethnic minority families' pathways to a dementia diagnosis using the concept of sense-making. Three case studies were drawn from 56 video interviews with family carers of older adults with dementia from Chinese, Arab and Indian backgrounds. Interviews were conducted across Australia from February to August 2018, then translated, transcribed and thematically analysed. Findings suggest families did not enter into formal care because of a crisis, instead navigating fragmented systems and conflicting advice to obtain a dementia diagnosis and access to relevant care. This experience was driven by sense-making (a search for plausible explanations) that involved family carers interpreting discrepant cues in changes to the behaviour of the person with dementia over time, managing conflicting (medical) advice about these discrepancies and reinterpreting their relationships with hindsight. The sense-making concept offers a more constructive hermeneutic than the 'family crisis' narrative as it illuminates the agency of carers' in understanding changed behaviours, negotiating services and managing personal, social and structural barriers pre-diagnosis. The concept also demonstrates the need for a multimodal approach to promoting timely diagnosis of dementia in ethnic minority communities through dementia awareness and literacy campaigns as well as initiatives that address structural inequities.

RESUMEN

Mass gatherings for sporting events, music shows, and religious needs continue to grow in our urban areas, requiring local authorities to develop safety procedures to mitigate the challenges of keeping the attendees safe. These challenges are even more pronounced at pilgrimage venues where social distancing and contact avoidance are difficult as pilgrims are required to perform various rituals in close proximity with others, in a sequential manner, either daily or weekly, as per their religious tenets. Over two million pilgrims attend the Hajj pilgrimage in Saudi Arabia annually. Keeping the local and visiting pilgrims safe from crowd crush, sunstroke, skin infections, recurrence of prior medical issues, and contagious diseases requires the Saudi government to allocate huge investments for health communication and prevention programs every year. However, there is no evidence to date that has empirically tested whether Hajj pilgrims' are able to receive such information and are subsequently adopting various health promoting behaviors. This study aims to do that by framing it within the Health Belief Model. Data collected and analyzed from 245 pilgrims in Makkah between September 9th-19th, 2017 suggests that roughly 48% of the pilgrims adopted all five protective measures. However, language barriers, limited health care facilities, and difficulties in purchasing prescription mediciens were cited as impediments to adopting healthy measures. The study concludes with recommendations for the KSA government agencies, Hajj authorities, Mission authorities and pilgrims, during various phases of travel-- i.e. pre-travel, during the pilgrimage and post-travel, in light of new emerging health threats.

RESUMEN

BACKGROUND: Subtotal tonsil surgery (tonsillotomy) remains a controversial procedure. We aimed to document bleeding rates and return to normal activity for total versus subtotal tonsil surgery in the paediatric population. METHODS: A 10-year cohort of 608 children from a single-surgeon series was analysed. Bleeding events were classified using the Flinders modification of the Stammberger criteria. Return to normal activity was defined as normal diet and return to childcare/school. RESULTS: A total of 8.3% of tonsil procedures and a subtotal of 1.8% of procedures had some kind of bleeding episode (P < 0.01; odds ratio 3.2; 95% confidence interval (CI) 1.3-7.6). When blood-stained sputum (type A bleed) was excluded, this dropped to 2.5% versus 0.3%, respectively (P < 0.05; odds ratio 8.5; 95% CI 1.2-96.0). Return to normal activities occurred at a mean of 11.1 (95% CI 9.7-12.5) versus 4.6 (95% CI 4.0-5.3) days, respectively (P < 0.0001). CONCLUSION: In this 10-year single surgeon series, subtotal tonsillectomy or 'tonsillotomy' was associated with a significant reduction in both prevalence and severity of bleeding, in addition to a more rapid return to normal activities when compared to total tonsillectomy.

RESUMEN

This article explores whether this extension of treatment and medication possibilities, owing to greater transnational movement of goods and people, presents increasing challenges for maintaining patients' trust within nationally-bound healthcare systems, such as in Australia. We ran focus groups in Melbourne from June 2012 to June 2013 with 34 Indian migrants to Australia. Our findings illustrate discrepancies between the symbolic mediation of trust within Indian and Australian healthcare encounters. We find that Indian participants associated authoritative and decisive self-presentation by doctors with medical competence, conflicting with Western patient choice models which exalt patient autonomy and agency. We also find that trust in Indian healthcare encounters is mediated through the symbolic deployment of "strong medication" and the engendering of "hope" in patients. Australian doctors' failure to deploy these symbols in the same way contributes to distrust that Indian participants express towards Australian health professionals and healthcare systems. We conclude that in situations where patients have less familiarity with the symbolic repertoire shared by the majority of users of a national healthcare system, such as can be the case with recent migrants, difficulties and misunderstandings may arise in negotiating trust, providing a potential motivator for seeking alternatives transnationally.

RESUMEN

OBJECTIVE: To assess whether access to saltwater chlorinated swimming pools in remote Aboriginal communities is beneficial in reducing levels of middle ear disease and hearing loss in school children. DESIGN: A prospective 3-year cohort study of children in 10 remote Aboriginal communities in South Australia with (n = 4) or without (n = 6) swimming pools. SETTING: Outback Australia. PARTICIPANTS: Eight hundred and thirteen school-age children residing in remote South Australia. MAIN OUTCOME MEASURES: Prevalence of open and closed middle ear disease and prevalence of hearing loss. RESULTS: About 2107 ear assessments were conducted during the study period. 70.7% of children in communities with pools failed a screening test of hearing compared with 68.6% of children in non-pool communities (P = 0.637). 32.3% of children had chronic otitis media (COM). There was no difference between pool and non-pool communities in the frequency of either inactive (19.4% pool vs 22.6% non-pool; P = 0.232) or active (19.8% pool vs 17.8% non-pool; P = 0.383) COM. In children with bilateral intact tympanic membranes, 21.2% had unilateral and 20.6 had bilateral type B tympanograms. There was no difference between pool and non-pool communities in the frequency of type B tympanometry (P = 0.465). CONCLUSIONS: Hearing loss associated with both open and closed middle ear disease remains highly prevalent in children living in remote Aboriginal communities in South Australia. Access to swimming pools in this population does not appear to significantly reduce these high levels of middle ear disease or associated hearing loss.

RESUMEN

This research focuses on the 2014 Ebola crisis response by emergency managers in the Dallas-Fort Worth (DFW) Metropolitan region in the State of Texas, U.S.A. It examines the patterns of crisis communication and the use of Standard Operating Procedures (SOPs) during the first month of the crisis. Primary data collected from 24 face-to-face interviews and 12 online surveys are analyzed. The research identifies elements contributing to organizational failures, which by their very nature gain public and media attention, and also explicates the less mentioned successful decisions made by response agencies in the DFW region. It is important to investigate both failures and successes to help inform organizational learning for better preparedness to future health crises. Findings suggest that, although there was a breakdown in communication between small city governments/ municipalities and higher levels of government at the State and Federal levels, prior training and collaborative relationships helped in improvised decision-making. Takeaways for practitioners include reiterating the importance of establishing SOPs, merits of flexibility, and improvisational decisions for shared learning.

RESUMEN

PURPOSE: There is a relative paucity of research regarding medication expenditure associated with multiple-therapy use for rhinitis in Australia. To describe 1) the nature and extent of multiple-therapy use for rhinitis in Australia using data on therapies purchased with prescription or over-the-counter (OTC) and 2) additional costs incurred by multiple-therapy use compared with intranasal corticosteroid (INCS) therapy alone. PATIENTS AND METHODS: A retrospective observational study was carried out using a database containing anonymous pharmacy transaction data available from 20% of pharmacies in Australia that links doctor prescriptions and OTC purchase information. Pharmacy purchases of at least one prescription or OTC rhinitis treatment, with or without additional asthma/chronic obstructive pulmonary disease (COPD) therapy, by patients during 2013 and 2014 were assessed. RESULTS: In total, 4,247,193 prescription and OTC rhinitis treatments were purchased from 909 pharmacies over 24 months. The majority of rhinitis therapy transactions were single-therapy purchases without additional asthma/COPD therapy. Of the single therapies purchased, 73% were oral antihistamines (OAHs) and 15% were INCS therapy. Dual-therapy purchases of INCSs and OAHs accounted for 40% of multiple-therapy purchases. Patients frequently purchased OAHs, nonsteroidal nasal sprays, and eye drops for allergic conjunctivitis alongside INCSs, resulting in higher financial costs (up to AU$21 per treatment episode) compared with INCS monotherapy. CONCLUSION: This study highlighted the significant burden posed on community pharmacy to address the needs of people with rhinitis symptoms, and the failure to translate the evidence that INCSs are the most effective monotherapy for moderate to severe and/or persistent rhinitis into clinical practice in light of the lack of evidence supporting combination of INCS and OAH therapy. Health care professional engagement, especially at the pharmacy level, will be extremely important if we wish to ensure that the purchase of rhinitis treatment is in accordance with guidelines and that their use is optimal.
