Screening and treatment of anxiety symptoms within an interdisciplinary comprehensive epilepsy center.

Youth with epilepsy (YWE) are at elevated risk for anxiety, yet anxiety is often undetected and understudied in this population. Most research on anxiety in YWE is based on parent proxy-report and broad-band measures with limited sensitivity. The aim of the current study was to: 1) examine rates of anxiety symptoms in YWE using a diagnosis-specific, self-report measure of anxiety symptoms, 2) assess differences in anxiety symptoms by sociodemographic and medical variables, and 3) evaluate changes in anxiety symptoms following a brief behavioral health intervention delivered within an interdisciplinary epilepsy clinic visit. As part of routine clinical care, 317 YWE [Mage=13.4+2.5 years (range 7-19 years); 54% female; 84% White: Non-Hispanic] completed the Multidimensional Anxiety Scale for Children, self-report (MASC-10), with a subset completing the MASC-10 at a second timepoint (n=139). A retrospective chart review was completed and sociodemographic, medical variables and behavioral health interventions were collected. Thirty percent of YWE endorsed elevated anxiety symptoms, with higher rates in those who were younger. YWE who received a behavioral health intervention for anxiety (n=21) demonstrated greater decreases in anxiety symptoms from Time 1 to Time 2 compared to those who did not receive a behavioral intervention (n=108). The integration of psychologists into pediatric epilepsy clinics may have allowed for early identification of anxiety symptoms, as well behavioral interventions to address these symptoms, which has the potential to decrease the need for more intensive services.

Cohort profile: GRACE - a residential aged care cohort examining factors influencing antimicrobial resistance carriage.

BACKGROUND: The emergence of antimicrobial-resistant bacteria represents a considerable threat to human health, particularly for vulnerable populations such as those living in residential aged care. However, antimicrobial resistance carriage and modes of transmission remain incompletely understood. The Generating evidence on antimicrobial Resistance in the Aged Care Environment (GRACE) study was established to determine principal risk factors of antimicrobial resistance carriage and transmission in residential aged care facilities (RACFs). This article describes the cohort characteristics, national representation, and planned analyses for this study. METHODS: Between March 2019 and March 2020, 279 participants were recruited from five South Australian RACFs. The median age was 88.6 years, the median period in residence was 681 days, and 71.7% were female. A dementia diagnosis was recorded in 54.5% and more than two thirds had moderate to severe cognitive impairment (68.8%). 61% had received at least one course of antibiotics in the 12 months prior to enrolment. RESULTS: To investigate the representation of the GRACE cohort to Australians in residential aged care, its characteristics were compared to a subset of the historical cohort of the Registry of Senior Australians (ROSA). This included 142,923 individuals who were permanent residents of RACFs on June 30th, 2017. GRACE and ROSA cohorts were similar in age, sex, and duration of residential care, prevalence of health conditions, and recorded dementia diagnoses. Differences were observed in care requirements and antibiotic exposure (both higher for GRACE participants). GRACE participants had fewer hospital visits compared to the ROSA cohort, and a smaller proportion were prescribed psycholeptic medications. CONCLUSIONS: We have assembled a cohort of aged care residents that is representative of the Australian aged care population, and which provides a basis for future analyses. Metagenomic data isolated from participants and built environments will be used to determine microbiome and resistome characteristics of an individual and the facility. Individual and facility risk exposures will be aligned with metagenomic data to identify principal determinants for antimicrobial resistance carriage. Ultimately, this analysis will inform measures aimed at reducing the emergence and spread of antimicrobial resistant pathogens in this high-risk population.

Vaccine Attitudes Mediate Relationships Between Caregiver Political Ideology and Likelihood of Child Vaccination for COVID-19.

INTRODUCTION: The COVID-19 vaccine has become available to children ages 5-12, yet vaccine uptake is suboptimal. Political ideology is a correlate of COVID-related beliefs and vaccine likelihood among US adults. However, since political ideology is not easily modifiable, attention to modifiable mechanisms that may explain links between political ideology and vaccine hesitancy is important in addressing this public health crisis. Caregiver attitudes around vaccine safety and efficacy have been related to vaccine uptake in other populations and warrant additional study in the context of COVID-19. The current study examined whether caregiver's attitudes regarding the safety and efficacy of the COVID-19 vaccine mediated the relationship between caregiver political ideology and likelihood of having their child vaccinated. METHODS: 144 US caregivers of children (6-12 years) completed an online survey in summer 2021 to assess political ideology, vaccine-related beliefs, and likelihood of having their child vaccinated against COVID-19. RESULTS: Caregivers with more liberal political views reported higher likelihood of eventual child vaccination compared to caregivers who reported a more conservative views (t(81) = 6.08, BCa CI [2.97, 5.67]). Moreover, parallel mediation models indicated caregiver?s perceptions of risks (BCa CI [-.98, -.10]) and efficacy (BCa CI [-3.16, -2.15]) of the vaccine each mediated the aforementioned relationship, with perceived efficacy explaining significantly more variance than risks. CONCLUSIONS: Findings extend knowledge by identifying social cognitive factors that impact caregiver vaccine hesitancy. Interventions to address caregiver's hesitancy to have their child vaccinated through modifying caregiver's inaccurate beliefs regarding vaccines or enhancing perceptions of vaccine efficacy is warranted.

Targeted reduction of airborne viral transmission risk in long-term residential aged care.

COVID-19 has demonstrated the devastating consequences of the rapid spread of an airborne virus in residential aged care. We report the use of CO2-based ventilation assessment to empirically identify potential 'super-spreader' zones within an aged care facility, and determine the efficacy of rapidly implemented, inexpensive, risk reduction measures.

Prevention of SARS-CoV-2 (COVID-19) transmission in residential aged care using ultraviolet light (PETRA): a two-arm crossover randomised controlled trial protocol.

BACKGROUND: SARS-CoV-2 poses a considerable threat to those living in residential aged care facilities (RACF). RACF COVID-19 outbreaks have been characterised by the rapid spread of infection and high rates of severe disease and associated mortality. Despite a growing body of evidence supporting airborne transmission of SARS-CoV-2, current infection control measures in RACF including hand hygiene, social distancing, and sterilisation of surfaces, focus on contact and droplet transmission. Germicidal ultraviolet (GUV) light has been used widely to prevent airborne pathogen transmission. Our aim is to investigate the efficacy of GUV technology in reducing the risk of SARS-CoV-2 infection in RACF. METHODS: A multicentre, two-arm double-crossover, randomised controlled trial will be conducted to determine the efficacy of GUV devices to reduce respiratory viral transmission in RACF, as an adjunct to existing infection control measures. The study will be conducted in partnership with three aged care providers in metropolitan and regional South Australia. RACF will be separated into paired within-site zones, then randomised to intervention order (GUV or control). The initial 6-week period will be followed by a 2-week washout before crossover to the second 6-week period. After accounting for estimated within-zone and within-facility correlations of infection, and baseline infection rates (10 per 100 person-days), a sample size of n = 8 zones (n = 40 residents/zone) will provide 89% power to detect a 50% reduction in symptomatic infection rate. The primary outcome will be the incidence rate ratio of combined symptomatic respiratory infections for intervention versus control. Secondary outcomes include incidence rates of hospitalisation for complications associated with respiratory infection; respiratory virus detection in facility air and fomite samples; rates of laboratory confirmed respiratory illnesses and genomic characteristics. DISCUSSION: Measures that can be deployed rapidly into RACF, that avoid the requirement for changes in resident and staff behaviour, and that are effective in reducing the risk of airborne SARS-CoV-2 transmission, would provide considerable benefit in safeguarding a highly vulnerable population. In addition, such measures might substantially reduce rates of other respiratory viruses, which contribute considerably to resident morbidity and mortality.

Hygiene along the continuum of care in the early post-natal period: an observational study in Nigeria.

BACKGROUND: Newborns delivered in healthcare facilities in low- and middle-income countries are at an increased risk of healthcare associated infections. Facility-based studies have focused primarily on healthcare worker behaviour during labour & delivery with limited attention to hygiene practices in post-natal care areas and largely ignore the wide variety of actors involved in maternal and neonatal care. METHODS: This exploratory mixed-methods study took place in six healthcare facilities in Nigeria where 31 structured observations were completed during post-natal care, discharge, and the first 6 hours after return to the home. Frequency of hand hygiene opportunities and hand hygiene actions were assessed for types of patient care (maternal and newborn care) and the role individuals played in caregiving (healthcare workers, cleaners, non-maternal caregivers). Qualitative interviews with mothers were completed approximately 1 week after facility discharge. RESULTS: Maternal and newborn care were performed by a range of actors including healthcare workers, mothers, cleaners and non-maternal caregivers. Of 291 hand hygiene opportunities observed at health facilities, and 459 observed in home environments, adequate hand hygiene actions were observed during only 1% of all hand hygiene opportunities. Adequate hand hygiene prior to cord contact was observed in only 6% (1/17) of cord contact related hand hygiene opportunities at healthcare facilities and 7% (2/29) in households. Discharge advice was infrequent and not standardised and could not be remembered by the mother after a week. Mothers reported discomfort around telling non-maternal caregivers to practice adequate hand hygiene for their newborn. CONCLUSIONS: In this setting, hand hygiene practices during post-natal care and the first 6 hours in the home environment were consistently inadequate. Effective strategies are needed to promote safe hand hygiene practices within the post-natal care ward and home in low resource, high-burden settings. Such strategies need to target not just mothers and healthcare workers but also other caregivers.

Determinants of clean birthing practices in low- and middle-income countries: a scoping review.

BACKGROUND: Infection is a leading cause of maternal and newborn mortality in low- and middle-income countries (LMIC). Clean birthing practices are fundamental to infection prevention efforts, but these are inadequate in LMIC. This scoping study reviews the literature on studies that describe determinants of clean birthing practices of healthcare workers or mothers during the perinatal period in LMIC. METHODS: We reviewed literature published between January 2000 and February 2018 providing information on behaviour change interventions, behaviours or behavioural determinants during the perinatal period in LMIC. Following a multi-stage screening process, we extracted key data manually from studies. We mapped identified determinants according to the COM-B behavioural framework, which posits that behaviour is shaped by three categories of determinants - capability, opportunity and motivation. RESULTS: Seventy-eight studies were included in the review: 47 observational studies and 31 studies evaluating an intervention. 51% had a household or community focus, 28% had a healthcare facility focus and 21% focused on both. We identified 31 determinants of clean birthing practices. Determinants related to clean birthing practices as a generalised set of behaviours featured in 50 studies; determinants related specifically to one or more of six predefined behaviours - commonly referred to as "the six cleans" - featured in 31 studies. Determinants of hand hygiene (n = 13) and clean cord care (n = 11) were most commonly reported. Reported determinants across all studies clustered around psychological capability (knowledge) and physical opportunity (access to resources). However, greater heterogeneity in reported behavioural determinants was found across studies investigating specific clean birthing practices compared to those studying clean birthing as a generalised set of behaviours. CONCLUSIONS: Efforts to combine clean birthing practices into a single suite of behaviours - such as the "six cleans"- may simplify policy and advocacy efforts. However, each clean practice has a unique set of determinants and understanding what drives or hinders the adoption of these individual practices is critical to designing more effective interventions to improve hygiene behaviours and neonatal and maternal health outcomes in LMIC. Current understanding in this regard remains limited. More theory-grounded formative research is required to understand motivators and social influences across different contexts.

Low energy availability surrogates correlate with health and performance consequences of Relative Energy Deficiency in Sport.

Low energy availability (EA) is suspected to be the underlying cause of both the Female Athlete Triad and the more recently defined syndrome, Relative Energy Deficiency in Sport (RED-S). The International Olympic Committee (IOC) defined RED-S as a syndrome of health and performance impairments resulting from an energy deficit. While the importance of adequate EA is generally accepted, few studies have attempted to understand whether low EA is associated with the health and performance consequences posited by the IOC. OBJECTIVE: The purpose of this cross-sectional study was to examine the association of low EA with RED-S health and performance consequences in a large clinical population of female athletes. METHODS: One thousand female athletes (15-30 years) completed an online questionnaire and were classified as having low or adequate EA. The associations between low EA and the health and performance factors listed in the RED-S models were evaluated using chi-squared test and the odds ratios were evaluated using binomial logistic regression (p<0.05). RESULTS: Athletes with low EA were more likely to be classified as having increased risk of menstrual dysfunction, poor bone health, metabolic issues, haematological detriments, psychological disorders, cardiovascular impairment and gastrointestinal dysfunction than those with adequate EA. Performance variables associated with low EA included decreased training response, impaired judgement, decreased coordination, decreased concentration, irritability, depression and decreased endurance performance. CONCLUSION: These findings demonstrate that low EA measured using self-report questionnaires is strongly associated with many health and performance consequences proposed by the RED-S models.

Antarctic emerald rockcod have the capacity to compensate for warming when uncoupled from CO2 -acidification.

Increases in atmospheric CO2 levels and associated ocean changes are expected to have dramatic impacts on marine ecosystems. Although the Southern Ocean is experiencing some of the fastest rates of change, few studies have explored how Antarctic fishes may be affected by co-occurring ocean changes, and even fewer have examined early life stages. To date, no studies have characterized potential trade-offs in physiology and behavior in response to projected multiple climate change stressors (ocean acidification and warming) on Antarctic fishes. We exposed juvenile emerald rockcod Trematomus bernacchii to three PCO2 treatments (~450, ~850, and ~1,200 µatm PCO2 ) at two temperatures (-1 or 2°C). After 2, 7, 14, and 28 days, metrics of physiological performance including cardiorespiratory function (heart rate [fH ] and ventilation rate [fV ]), metabolic rate (M˙O2), and cellular enzyme activity were measured. Behavioral responses, including scototaxis, activity, exploration, and escape response were assessed after 7 and 14 days. Elevated PCO2 independently had little impact on either physiology or behavior in juvenile rockcod, whereas warming resulted in significant changes across acclimation time. After 14 days, fH , fV and M˙O2 significantly increased with warming, but not with elevated PCO2 . Increased physiological costs were accompanied by behavioral alterations including increased dark zone preference up to 14%, reduced activity by 12%, as well as reduced escape time suggesting potential trade-offs in energetics. After 28 days, juvenile rockcod demonstrated a degree of temperature compensation as fV , M˙O2, and cellular metabolism significantly decreased following the peak at 14 days; however, temperature compensation was only evident in the absence of elevated PCO2 . Sustained increases in fV and M˙O2 after 28 days exposure to elevated PCO2 indicate additive (fV ) and synergistic (M˙O2) interactions occurred in combination with warming. Stressor-induced energetic trade-offs in physiology and behavior may be an important mechanism leading to vulnerability of Antarctic fishes to future ocean change.

3D bioprinting mesenchymal stem cell-laden construct with core-shell nanospheres for cartilage tissue engineering.

Cartilage tissue is prone to degradation and has little capacity for self-healing due to its avascularity. Tissue engineering, which provides artificial scaffolds to repair injured tissues, is a novel and promising strategy for cartilage repair. 3D bioprinting offers even greater potential for repairing degenerative tissue by simultaneously integrating living cells, biomaterials, and biological cues to provide a customized scaffold. With regard to cell selection, mesenchymal stem cells (MSCs) hold great capacity for differentiating into a variety of cell types, including chondrocytes, and could therefore be utilized as a cartilage cell source in 3D bioprinting. In the present study, we utilize a tabletop stereolithography-based 3D bioprinter for a novel cell-laden cartilage tissue construct fabrication. Printable resin is composed of 10% gelatin methacrylate (GelMA) base, various concentrations of polyethylene glycol diacrylate (PEGDA), biocompatible photoinitiator, and transforming growth factor beta 1 (TGF-ß1) embedded nanospheres fabricated via a core-shell electrospraying technique. We find that the addition of PEGDA into GelMA hydrogel greatly improves the printing resolution. Compressive testing shows that modulus of the bioprinted scaffolds proportionally increases with the concentrations of PEGDA, while swelling ratio decreases with the increase of PEGDA concentration. Confocal microscopy images illustrate that the cells and nanospheres are evenly distributed throughout the entire bioprinted construct. Cells grown on 5%/10% (PEGDA/GelMA) hydrogel present the highest cell viability and proliferation rate. The TGF-ß1 embedded in nanospheres can keep a sustained release up to 21 d and improve chondrogenic differentiation of encapsulated MSCs. The cell-laden bioprinted cartilage constructs with TGF-ß1-containing nanospheres is a promising strategy for cartilage regeneration.

Peripheral Retinal Imaging Biomarkers for Alzheimer's Disease: A Pilot Study.

PURPOSE: To examine whether ultra-widefield (UWF) retinal imaging can identify biomarkers for Alzheimer's disease (AD) and its progression. METHODS: Images were taken using a UWF scanning laser ophthalmoscope (Optos P200C AF) to determine phenotypic variations in 59 patients with AD and 48 healthy controls at baseline (BL). All living participants were invited for a follow-up (FU) after 2 years and imaged again (if still able to participate). All participants had blood taken for genotyping at BL. Images were graded for the prevalence of age-related macular degeneration-like pathologies and retinal vascular parameters. Comparison between AD patients and controls was made using the Student t test and the χ2 test. RESULTS: Analysis at BL revealed a significantly higher prevalence of a hard drusen phenotype in the periphery of AD patients (14/55; 25.4%) compared to controls (2/48; 4.2%) [χ2 = 9.9, df = 4, p = 0.04]. A markedly increased drusen number was observed at the 2-year FU in patients with AD compared to controls. There was a significant increase in venular width gradient at BL (zone C: 8.425 × 10-3 ± 2.865 × 10-3 vs. 6.375 × 10-3 ± 1.532 × 10-3, p = 0.008; entire image: 8.235 × 10-3 ± 2.839 × 10-3 vs. 6.050 × 10-3 ± 1.414 × 10-3, p = 0.004) and a significant decrease in arterial fractal dimension in AD at BL (entire image: 1.250 ± 0.086 vs. 1.304 ± 0.089, p = 0.049) with a trend for both at FU. CONCLUSIONS: UWF retinal imaging revealed a significant association between AD and peripheral hard drusen formation and changes to the vasculature beyond the posterior pole, at BL and after clinical progression over 2 years, suggesting that monitoring pathological changes in the peripheral retina might become a valuable tool in AD monitoring.

Juvenile Antarctic rockcod (Trematomus bernacchii) are physiologically robust to CO2-acidified seawater.

To date, numerous studies have shown negative impacts of CO2-acidified seawater (i.e. ocean acidification, OA) on marine organisms, including calcifying invertebrates and fishes; however, limited research has been conducted on the physiological effects of OA on polar fishes and even less on the impact of OA on early developmental stages of polar fishes. We evaluated aspects of aerobic metabolism and cardiorespiratory physiology of juvenile emerald rockcod, ITALIC! Trematomus bernacchii, an abundant fish in the Ross Sea, Antarctica, to elevated partial pressure of carbon dioxide ( ITALIC! PCO2 ) [420 (ambient), 650 (moderate) and 1050 (high) µatm ITALIC! PCO2 ] over a 1 month period. We examined cardiorespiratory physiology, including heart rate, stroke volume, cardiac output and ventilation rate, whole organism metabolism via oxygen consumption rate and sub-organismal aerobic capacity by citrate synthase enzyme activity. Juvenile fish showed an increase in ventilation rate under high ITALIC! PCO2 compared with ambient ITALIC! PCO2 , whereas cardiac performance, oxygen consumption and citrate synthase activity were not significantly affected by elevated ITALIC! PCO2 Acclimation time had a significant effect on ventilation rate, stroke volume, cardiac output and citrate synthase activity, such that all metrics increased over the 4 week exposure period. These results suggest that juvenile emerald rockcod are robust to near-future increases in OA and may have the capacity to adjust for future increases in ITALIC! PCO2  by increasing acid-base compensation through increased ventilation.

Phenomenal advanced age of pupping in a captive Pacific harbor seal (Phoca vitulina richardsi).

To better define the life history in the captive environment, we describe the reproductive history and advanced age of pupping of a female Pacific harbor seal (Phoca vitulina richardsi) at the Henry Vilas Zoo (HVZ) in Madison, Wisconsin. This female gave birth to a viable pup on May 16, 2012, at the age of 42 years and is the oldest documented birth reported for this species. This female also demonstrated high temporal fidelity to her previously described birth timing. The pup's sire was also 42 years at the time of birth. Captive harbor seals can remain reproductively healthy into their 5th decade.

Patient and healthcare provider perceptions of acceptability of fingerstick point-of-care hepatitis C testing at Aboriginal Community Controlled Health Services in Australia.

BACKGROUND: Hepatitis C (HCV) is highly prevalent in First Nations communities globally. Barriers in the uptake of testing and treatment create challenges to realise elimination of HCV in these communities. In efforts to reduce barriers to testing and treatment, the SCALE-C study implemented an HCV test-and-treat intervention integrating point-of-care HCV testing and FibroScan®. SCALE-C was carried out at four Aboriginal Community Controlled Health Services (ACCHS; renowned for providing culturally safe care) in four regional towns in Australia. This qualitative analysis sought to understand healthcare provider and patient perceptions of acceptability of a community-based HCV test-and-treat intervention within ACCHS. METHODS: Semi-structured interviews were undertaken with 23 patient participants and 14 healthcare personnel (including Aboriginal Health Workers/Practitioners, nurses, general practitioners, and practice managers) from across the four ACCHS involved in SCALE-C. A coding framework was developed among study authors and informed by Sekhon's Theoretical Framework of Acceptability. RESULTS: The SCALE-C intervention enabled opportunities for healthcare providers to listen to patients, and for patients to feel heard (affective attitude). HCV testing was opportunistic and often occurred outside of the allocated SCALE-C clinical hours (burden). For patients, HCV testing within SCALE-C was viewed as a moral responsibility and ensured protection of self and others (ethicality). For personnel, SCALE-C (including following up visits) was regarded as an opportunity to engage with patients especially those with complex health needs which may be unrelated to HCV risk factors (ethicality). Patients and personnel widely regarded the SCALE-C intervention to be effective, and the test-and-treat model was preferable for both patients and personnel. CONCLUSION: The SCALE-C intervention was broadly perceived to be acceptable among both healthcare providers and patients within ACCHS. Whilst the prioritisation of HCV was viewed as increasing patient engagement, it was also regarded as an opportunity for addressing other healthcare needs within Aboriginal communities. HCV test-and-treat models of care delivered by ACCHS simplify the HCV care pathway and ensure all HCV care is provided in a culturally safe setting (e.g., patients did not need to attend external services such as pathology).

The development and validation of the One Health Community Assessment.

Interdisciplinary collaborations to address human, animal, and environmental health have been emphasized since the inception of the One Health framework. A quantitative survey instrument was developed to measure perceptions of the impacts of pets on One Health. Using the exploratory sequential mixed methods approach, 20 interviews were conducted with individuals from a racially diverse and low-socioeconomic status community in the U.S. to understand their perceptions of One Health. Data from those interviews informed the development of a Likert scale survey measuring individual perceptions of community, human, pet, and environmental health and welfare, as well as the connections between the domains of the One Health triad (human, animal, and environment). The resulting One Health Community Assessment (OHCA) was administered in two urban and two rural underserved U.S. communities longitudinally (2018-2021) through door-to-door data collection as well as phone, email, and text surveys. Validation of the instrument was completed using data collected in the third and fourth years of the study (n = 654). Factor analysis with orthogonal varimax rotation was used to assess the structure and internal consistency of the OHCA. Five subscales explained 42.4% of the variance in our 92-item instrument: community health (Cronbach's α = 0.897), human health (α = 0.842), pet health (α = 0.899), environmental health (α = 0.789), and connections between domains of One Health (α = 0.762). The OHCA represents the first reliable and validated instrument to measure the impacts of pets on One Health.

A regulatory toolbox of MiniPromoters to drive selective expression in the brain.

The Pleiades Promoter Project integrates genomewide bioinformatics with large-scale knockin mouse production and histological examination of expression patterns to develop MiniPromoters and related tools designed to study and treat the brain by directed gene expression. Genes with brain expression patterns of interest are subjected to bioinformatic analysis to delineate candidate regulatory regions, which are then incorporated into a panel of compact human MiniPromoters to drive expression to brain regions and cell types of interest. Using single-copy, homologous-recombination "knockins" in embryonic stem cells, each MiniPromoter reporter is integrated immediately 5' of the Hprt locus in the mouse genome. MiniPromoter expression profiles are characterized in differentiation assays of the transgenic cells or in mouse brains following transgenic mouse production. Histological examination of adult brains, eyes, and spinal cords for reporter gene activity is coupled to costaining with cell-type-specific markers to define expression. The publicly available Pleiades MiniPromoter Project is a key resource to facilitate research on brain development and therapies.

Distinctive Optical Coherence Tomography Angiography and Indocyanine Green Angiography Imaging Patterns in Topiramate-Induced Choroidal Effusion.

PURPOSE: To describe novel findings seen on optical coherence tomography angiography (OCTA) and indocyanine green angiography (ICGA) in a young male patient presenting with bilateral topiramate-induced choroidal effusion. METHODS: Retrospective case report. A comprehensive ophthalmic examination was conducted and multimodal imaging techniques, including B-scan ultrasound, OCT, OCTA, and ICGA were analyzed. RESULTS: A male in his 30s presented with a myopic shift due to bilateral choroidal effusion induced by a medication containing topiramate prescribed for weight loss. ICGA showed multiple hypofluorescent spots within the choroid corresponding to areas of reduced OCTA flow signal in both the inner and deeper en face choroidal slabs. Symptoms and abnormal imaging findings resolved within five days of discontinuing the medication. CONCLUSION: Findings observed with OCTA and ICGA together suggest multifocal reversible areas of reduced choroidal vascular flow occurring in a topiramate-induced choroidal effusion. We propose that this transient hypoperfusion is due to compression from deeper choroidal vessels with a congested choroid.

Preventing empirical antibiotic treatment failure in migrant populations: screening by infection risk, not ethnic background.

Multidrug-resistant organisms (MDROs) are a major international health threat. In many low and middle-income countries poorly regulated antibiotic use, limited surveillance, and inadequate sanitation give rise to high rates of antibiotic resistance. A resulting reliance on last-line antibiotic options further contributes to the emergence of MDROs. The potential for these pathogens to spread across international borders is a matter of considerable concern. However, this problem is commonly framed as primarily a threat to the health security of countries where resistance is not yet endemic. In fact, it is little acknowledged that those at greatest risk from antibiotic treatment failure are individuals who move from regions of high MDRO prevalence to settings where standard empirical treatment options remain largely effective. In this perspective, we highlight the poor treatment outcomes for disseminated bacterial infections in individuals who have moved from settings in which MDROs are common to those where MDROs are currently less common. We discuss MDRO screening strategies that could avoid stigmatizing vulnerable populations by focusing on future risk of disseminated infection, rather than past risk of acquisition. In practical terms, this means screening individuals before childbirth, immunosuppressive treatments, major surgery, or other events associated with disseminated infection risk, rather than prioritizing screening for individuals from regions with high carriage rates. We argue that such measures would reduce antibiotic treatment failure and improve outcomes while protecting migrant populations from the divisive consequences of targeted screening programs.

A Trainee-Led Quality Improvement Project Using Change Management Theory to Improve Bedside Rounding.

OBJECTIVE: The coronavirus disease 2019 pandemic disrupted the practice of family-centered rounds. After the height of the pandemic, a trainee-led team identified a low percentage of bedside rounds on general pediatrics resident teams and combined a quality improvement framework and change management theory to increase bedside rounds. Initial efforts focused on a single general pediatrics team with the aim to increase bedside rounds from 18% to 50% within 6 months and sustain improvement for 12 months. A second aim was to increase bedside rounds from 7% to 50% for all general pediatrics resident teams within 6 months of spread. METHODS: The Model for Improvement informed the identification of 3 primary drivers of bedside rounds: knowledge, culture, and logistics. Twelve plan-do-study-act (PDSA) cycles were implemented. Measures included the percentage of bedside rounds (primary outcome), caregiver attendance (secondary outcome), and nurse attendance and rounding time (balancing measures). RESULTS: For the initial team, 13 522 patient days were analyzed for the primary outcome with the average percentage of weekly bedside rounds increasing from 18% to 89% with 12 months of sustained improvement. The spread of the intervention to all teams revealed an increase in bedside rounding from 7% to 54%. The most significant improvements occurred after PDSA cycle 2, a communication bundle, and PDSA cycle 5, when the project was spread to all teams. CONCLUSIONS: This trainee-led initiative reveals the strength of the incorporation of change management theory within a quality improvement framework, resulting in rapid and sustainable increase in bedside rounds.
