Assessment of knowledge, attitude and practice for oxygen therapy among medical staff at the Colonial War Memorial Hospital in Fiji. Intern Med J 2024; 54:657-663. [PMID: 37615066 DOI: 10.1111/imj.16210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 07/31/2023] [Indexed: 08/25/2023]
Abstract
BACKGROUND Oxygen therapy (OT) is a commonly prescribed essential medicine for people of all ages in the management of hypoxia. The adverse effects of inappropriate OT supplementation may be underestimated by health professionals and lead to poor health outcomes among hospitalised patients. Knowledge, attitude and practice (KAP) assessments of medical staff members to OT guidelines are essential to ensure optimal patient care. AIMS To perform a KAP assessment of OT administration among doctors and nurses employed at the national hospital of Fiji in 2021. METHODS Prospective cross-sectional study design. KAP assessment was performed with an online questionnaire and clinical observation. RESULTS The study population (N = 116) consisted of doctors (20.7%) and nurses (79.3%) representing the acute medical, burns, cardiac care, intensive care, surgical and postanaesthetic recovery units. Overall, the proportion of participants who obtained a good score (>70%) was 87% for knowledge, 87.93% for attitudes and 84% for practice. Best knowledge scores were obtained for general OT indications (71%) and scenarios where immediate oxygen application is required (70%). Lowest knowledge scores were for OT contraindications (14%) and oxygen saturation for acute myocardial infarction (32%), asthma (36%) and healthy newborns (43%). The most positive attitudes were in response to the statement that OT guidelines are essential (96%). A total of 78 (80.4%) patients were being cared for with good OT practice. CONCLUSIONS Good KAP scores were obtained for medical staff in Fiji regarding OT administration. Ongoing professional education activities should include updated training of OT contraindications and optimal oxygen saturation levels for special patient groups.

Abstract
Objective To evaluate whether there is an enrichment of rare variants in familial hemophagocytic lymphohistiocytosis (HLH) genes and systemic juvenile idiopathic arthritis (sJIA) with or without macrophage activation syndrome (MAS). Methods Targeted sequencing of HLH genes (LYST, PRF1, RAB27A, STX11, STXBP2, UNC13D) was performed in sJIA subjects from an established cohort. Sequence data from control subjects were obtained in silico (dbGaP:phs000280.v8.p2). Rare variant association testing (RVT) was performed with sequence kernel association test (SKAT) package. Significance was defined as p<0.05 after 100,000 permutations. Results Sequencing data from 524 sJIA cases were jointly called and harmonized with exome-derived target data from 3000 controls. Quality control operations produced a set of 481 cases and 2924 ancestrally-matched control subjects. RVT of sJIA cases and controls revealed a significant association with rare protein-altering variants (minor allele frequency [MAF]<0.01) of STXBP2 (p=0.020), and ultra-rare variants (MAF<0.001) of STXBP2 (p=0.007) and UNC13D (p=0.045). A subanalysis of 32 cases with known MAS and 90 without revealed significant association of rare UNC13D variants (p=0.0047). Additionally, sJIA patients more often carried ≥2 HLH variants than did controls (p=0.007), driven largely by digenic combinations involving LYST. Conclusion We identified an enrichment of rare HLH variants in sJIA patients compared with healthy controls, driven by STXBP2 and UNC13D. Biallelic variation in HLH genes was associated with sJIA, driven by LYST. Only UNC13D displayed enrichment in patients with MAS. This suggests that HLH variants may contribute to the pathophysiology of sJIA, even without MAS.

Developing a novel dual-injection FDG-PET imaging methodology to study the functional neuroanatomy of gait. Neuroimage 2024; 288:120531. [PMID: 38331333 DOI: 10.1016/j.neuroimage.2024.120531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 01/26/2024] [Accepted: 02/05/2024] [Indexed: 02/10/2024] Open
Abstract
Gait is an excellent indicator of physical, emotional, and mental health. Previous studies have shown that gait impairments in ageing are common, but the neural basis of these impairments are unclear. Existing methodologies are suboptimal and novel paradigms capable of capturing neural activation related to real walking are needed. In this study, we used a hybrid PET/MR system and measured glucose metabolism related to both walking and standing with a dual-injection paradigm in a single study session. For this study, 15 healthy older adults (10 females, age range: 60.5-70.7 years) with normal cognition were recruited from the community. Each participant received an intravenous injection of [18F]-2-fluoro-2-deoxyglucose (FDG) before engaging in two distinct tasks, a static postural control task (standing) and a walking task. After each task, participants were imaged. To discern independent neural functions related to walking compared to standing, we applied a bespoke dose correction to remove the residual 18F signal of the first scan (PETSTAND) from the second scan (PETWALK) and proportional scaling to the global mean, cerebellum, or white matter (WM). Whole-brain differences in walking-elicited neural activity measured with FDG-PET were assessed using a one-sample t-test. In this study, we show that a dual-injection paradigm in healthy older adults is feasible with biologically valid findings. Our results with a dose correction and scaling to the global mean showed that walking, compared to standing, increased glucose consumption in the cuneus (Z = 7.03), the temporal gyrus (Z = 6.91) and the orbital frontal cortex (Z = 6.71). Subcortically, we observed increased glucose metabolism in the supraspinal locomotor network including the thalamus (Z = 6.55), cerebellar vermis and the brainstem (pedunculopontine/mesencephalic locomotor region). Exploratory analyses using proportional scaling to the cerebellum and WM returned similar findings. Here, we have established the feasibility and tolerability of a novel method capable of capturing neural activations related to actual walking and extended previous knowledge including the recruitment of brain regions involved in sensory processing. Our paradigm could be used to explore pathological alterations in various gait disorders.

The impact of the COVID-19 pandemic on antenatal care provision and associated mental health, obstetric and neonatal outcomes. J Perinat Med 2024; 52:222-229. [PMID: 37883210 DOI: 10.1515/jpm-2023-0196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 09/28/2023] [Indexed: 10/28/2023]
Abstract
OBJECTIVES The COVID-19 pandemic imposed many challenges on pregnant women, including rapid changes to antenatal care aimed at reducing the societal spread of the virus. This study aimed to assess how the pandemic affected perinatal mental health and other pregnancy and neonatal outcomes in a tertiary unit in Queensland, Australia. METHODS This was a retrospective cohort study of pregnant women booked for care between March 2019 - June 2019 and March 2020 - June 2020. A total of 1984 women were included with no confirmed cases of COVID-19. The primary outcome of this study was adverse maternal mental health defined as an Edinburgh Postnatal Depression Scale score of ≥13 or an affirmative response to 'EPDS Question 10'. Secondary outcomes were preterm birth <37 weeks and <32 weeks, mode of birth, low birth weight, malpresentation in labour, hypertensive disease, anaemia, iron/vitamin B12 deficiency, stillbirth and a composite of neonatal morbidity and mortality. RESULTS There were no differences in the primary perinatal mental health outcomes. The rates of composite adverse neonatal outcomes (27 vs. 34 %, p<0.001) during the pandemic were higher; however, there was no difference in perinatal mortality (p=1.0), preterm birth (p=0.44) or mode of delivery (p=0.38). CONCLUSIONS Although there were no adverse consequences on maternal mental health during the pandemic, there was a concerning increase in neonatal morbidity potentially due to the altered model of maternity care implemented in the early COVID-19 pandemic.

Comparison of SP263 and 22C3 immunohistochemistry PD-L1 assays for clinical efficacy of adjuvant atezolizumab in non-small cell lung cancer: results from the randomized phase III IMpower010 trial. J Immunother Cancer 2023; 11:e007047. [PMID: 37903590 PMCID: PMC10619123 DOI: 10.1136/jitc-2023-007047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/07/2023] [Indexed: 11/01/2023] Open
Abstract
BACKGROUND Tumor samples from the phase III IMpower010 study were used to compare two programmed death-ligand 1 (PD-L1) immunohistochemistry assays (VENTANA SP263 and Dako 22C3) for identification of PD-L1 patient subgroups (negative, positive, low, and high expression) and their predictive value for adjuvant atezolizumab compared with best supportive care (BSC) in resectable early-stage non-small cell lung cancer (NSCLC). METHODS PD-L1 expression was assessed by the SP263 assay, which measured the percentage of tumor cells with any membranous PD-L1 staining, and the 22C3 assay, which scored the percentage of viable tumor cells showing partial or complete membranous PD-L1 staining. RESULTS When examining the concordance at the PD-L1-positive threshold (SP263: tumor cell (TC)≥1%; 22C3: tumor proportion score (TPS)≥1%), the results were concordant between assays for 83% of the samples. Similarly, at the PD-L1-high cut-off (SP263: TC≥50%; 22C3: TPS≥50%), the results were concordant between assays for 92% of samples. The disease-free survival benefit of atezolizumab over BSC was comparable between assays for PD-L1-positive (TC≥1% by SP263: HR, 0.58 (95% CI: 0.40 to 0.85) vs TPS≥1% by 22C3: HR, 0.65 (95% CI: 0.45 to 0.95)) and PD-L1-high (TC≥50% by SP263: HR, 0.27 (95% CI: 0.14 to 0.53) vs TPS≥50% by 22C3: HR, 0.31 (95% CI: 0.16 to 0.60)) subgroups. CONCLUSIONS The SP263 and 22C3 assays showed high concordance and a comparable clinical predictive value of atezolizumab at validated PD-L1 thresholds, suggesting that both assays can identify patients with early-stage NSCLC most likely to experience benefit from adjuvant atezolizumab. TRIAL REGISTRATION NUMBER NCT02486718.

Overall survival with adjuvant atezolizumab after chemotherapy in resected stage II-IIIA non-small-cell lung cancer (IMpower010): a randomised, multicentre, open-label, phase III trial. Ann Oncol 2023; 34:907-919. [PMID: 37467930 DOI: 10.1016/j.annonc.2023.07.001] [Citation(s) in RCA: 27] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 06/30/2023] [Accepted: 07/03/2023] [Indexed: 07/21/2023] Open
Abstract
BACKGROUND IMpower010 (NCT02486718) demonstrated significantly improved disease-free survival (DFS) with adjuvant atezolizumab versus best supportive care (BSC) following platinum-based chemotherapy in the programmed death-ligand 1 (PD-L1)-positive and all stage II-IIIA non-small-cell lung cancer (NSCLC) populations, at the DFS interim analysis. Results of the first interim analysis of overall survival (OS) are reported here. PATIENT AND METHODS The design, participants, and primary-endpoint DFS outcomes have been reported for this phase III, open-label, 1 : 1 randomised study of atezolizumab (1200 mg q3w; 16 cycles) versus BSC after adjuvant platinum-based chemotherapy (1-4 cycles) in adults with completely resected stage IB (≥4 cm)-IIIA NSCLC (per the Union Internationale Contre le Cancer and American Joint Committee on Cancer staging system, 7th edition). Key secondary endpoints included OS in the stage IB-IIIA intent-to-treat (ITT) population and safety in randomised treated patients. The first pre-specified interim analysis of OS was conducted after 251 deaths in the ITT population. Exploratory analyses included OS by baseline PD-L1 expression level (SP263 assay). RESULTS At a median of 45.3 months' follow-up on 18 April 2022, 127 of 507 patients (25%) in the atezolizumab arm and 124 of 498 (24.9%) in the BSC arm had died. The median OS in the ITT population was not estimable; the stratified hazard ratio (HR) was 0.995 [95% confidence interval (CI) 0.78-1.28]. The stratified OS HRs (95% CI) were 0.95 (0.74-1.24) in the stage II-IIIA (n = 882), 0.71 (0.49-1.03) in the stage II-IIIA PD-L1 tumour cell (TC) ≥1% (n = 476), and 0.43 (95% CI 0.24-0.78) in the stage II-IIIA PD-L1 TC ≥50% (n = 229) populations. Atezolizumab-related adverse event incidences remained unchanged since the previous analysis [grade 3/4 in 53 (10.7%) and grade 5 in 4 (0.8%) of 495 patients, respectively]. CONCLUSIONS Although OS remains immature for the ITT population, these data indicate a positive trend favouring atezolizumab in PD-L1 subgroup analyses, primarily driven by the PD-L1 TC ≥50% stage II-IIIA subgroup. No new safety signals were observed after 13 months' additional follow-up. Together, these findings support the positive benefit-risk profile of adjuvant atezolizumab in this setting.

"Echoes of a dark past" is a history of maternal childhood maltreatment a perinatal risk factor for pregnancy and postpartum trauma experiences? A longitudinal study. BMC Pregnancy Childbirth 2023; 23:397. [PMID: 37248446 DOI: 10.1186/s12884-023-05714-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 05/17/2023] [Indexed: 05/31/2023] Open
Abstract
BACKGROUND Although associations between maternal exposure to adverse childhood experiences (ACEs) and perinatal anxiety and depression are established, there is a paucity of information about the associations between ACEs and perinatal trauma and perinatal post-traumatic stress outcomes. For the purposes of this article, perinatal trauma is defined as a very frightening or distressing event that may result in psychological harm. The event must have been related to conception, pregnancy, birth, and up to 12 months postpartum. METHODS Women recruited at an antenatal appointment (n = 262) were invited to complete online surveys at two-time points; mid-pregnancy and eight weeks after the estimated date of delivery. The ACE Q 10-item self-reporting tool and a perinatal trauma screen related to the current and/or a previous perinatal period were completed. If the perinatal trauma screen was positive at either time point in the study, women were invited to complete a questionnaire examining symptoms of perinatal post-traumatic stress disorder and, if consenting, a clinical interview where the Post-traumatic Symptoms Scale was administered. RESULTS Sixty women (22.9%) reported four or more ACEs. These women were almost four times more likely to endorse perinatal trauma, when compared with those who either did not report ACEs (OR = 3.6, CI 95% 1.74 - 7.36, p < 0.001) or had less than four ACEs (OR = 3.9, CI 95% 2.037.55, p < 0.001). A 6-sevenfold increase in perinatal trauma was seen amongst women who reported having at least one ACE related to abuse (OR = 6.23, CI 95% 3.32-11.63, p < 0.001) or neglect (OR = 6.94, CI 95% 2.95-16.33, p < 0.001). The severity of perinatal-PTSD symptoms for those with perinatal trauma in pregnancy was significantly higher in those women exposed to at least one ACE related to abuse. CONCLUSIONS Awareness of maternal exposure to childhood adversity/maltreatment is critical to providing trauma-informed approaches in the perinatal setting. Our study suggests that routine screening for ACEs in pregnancy adds clinical value. This adds to previous research confirming the relationship between ACEs and mental health complexities and suggests that ACEs influence perinatal mental health outcomes.

Abstract
BACKGROUND Returning to education (RtE) after an acquired brain injury (ABI) can be stressful for children/young people (CYP) and families. While much can be done to support RtE, there has been limited exploration of the lived experience of parents/carers about what can both help and hinder the process. OBJECTIVE The aim was to understand more about RtE from parents' perspectives to inform best practice and facilitate improvements in service delivery. METHODS A service evaluation explored parent/carer views about the RtE process and the support received from healthcare professionals at a regional centre in the UK. Questionnaires (n = 59) were sent to parents of patients treated for an ABI in the last two years. RESULTS 31 parents (response rate = 51%) completed the survey. Results highlight the many challenges of RtE. Thematic analysis of responses revealed six key themes: Parental mindset and growth; What do they need know?; Specialist support and information; Talk and share; Challenges of new and hidden needs; and Don't forget them! CONCLUSION Parents offer crucial insight into the challenges of the RtE process. Their feedback highlights important factors for service development and reminds professionals of the key components of an effective return.

National Public Health Surveillance of Corporations in Key Unhealthy Commodity Industries - A Scoping Review and Framework Synthesis. Int J Health Policy Manag 2023; 12:6876.

Abstract
BACKGROUND Corporations in unhealthy commodity industries (UCIs) have growing influence on the health of national populations through practices that lead to increased consumption of unhealthy products. The use of government-led public health surveillance is best practice to better understand any emerging public health threat. However, there is minimal systematic evidence, generated and monitored by national governments, regarding the scope of UCI corporate practices and their impacts. This study aims to synthesise current frameworks that exist to identify and monitor UCI influence on health to highlight the range of practices deployed by corporations and inform future surveillance efforts in key UCIs. METHODS Seven biomedical, business and scientific databases were searched to identify literature focused on corporate practices that impact human health and frameworks for monitoring or assessment of the way UCIs impact health. Content analysis occurred in three phases, involving (1) the identification of framework documents in the literature and extraction of all corporate practices from the frameworks; (2) initial inductive grouping and synthesis followed by deductive synthesis using Lima and Galea's 'vehicles of power' as a heuristic; and (3) scoping for potential indicators linked to each corporate practice and development of an integrated framework. RESULTS Fourteen frameworks were identified with 37 individual corporate practices which were coded into five different themes according the Lima and Galea 'Corporate Practices and Health' framework. We proposed a summary framework to inform the public health surveillance of UCIs which outlines key actors, corporate practices and outcomes that should be considered. The proposed framework draws from the health policy triangle framework and synthesises key features of existing frameworks. CONCLUSION Systematic monitoring of the practices of UCIs is likely to enable governments to mitigate the negative health impacts of corporate practices. The proposed synthesised framework highlights the range of practices deployed by corporations for public health surveillance at a national government level. We argue there is significant precedent and great need for monitoring of these practices and the operationalisation of a UCI monitoring system should be the object of future research.

Abstract
OBJECTIVES This study sought to evaluate the prevalence, timing of onset and duration of symptoms of depression in the perinatal period (PND) in women with depression, according to whether they had a history of depression prior to their first perinatal period. We further sought to identify biopsychosocial correlates of perinatal symptoms in women with depression. DESIGN AND SETTING The Australian Genetics of Depression Study is an online case cohort study of the aetiology of depression. For a range of variables, women with depression who report significant perinatal depressive symptoms were compared with women with lifetime depression who did not experience perinatal symptoms. PARTICIPANTS In a large sample of parous women with major depressive disorder (n=7182), we identified two subgroups of PND cases with and without prior depression history (n=2261; n=878, respectively). PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome measure was a positive screen for PND on the lifetime version of the Edinburgh Postnatal Depression Scale. Descriptive measures reported lifetime prevalence, timing of onset and duration of PND symptoms. There were no secondary outcome measures. RESULTS The prevalence of PND among parous women was 70%. The majority of women reported at least one perinatal episode with symptoms both antenatally and postnatally. Of women who experienced depression prior to first pregnancy, PND cases were significantly more likely to report more episodes of depression (OR=1.15 per additional depression episode, 95% CI 1.13 to 1.17, p<0.001), non-European ancestry (OR 1.5, 95% CI 1.0 to 2.1, p=0.03), severe nausea during pregnancy (OR 1.3, 95% CI 1.1 to 1.6, p=0.006) and emotional abuse (OR 1.4, 95% CI 1.1 to 1.7, p=0.005). CONCLUSIONS The majority of parous women with lifetime depression in this study experienced PND, associated with more complex, severe depression. Results highlight the importance of perinatal assessments of depressive symptoms, particularly for women with a history of depression or childhood adverse experiences.

Abstract
OBJECTIVE The aims of this study were to describe firearm storage practices in homes of patients evaluated for mental health (MH) complaints at a tertiary care children's hospital and to describe storage practice changes after treatment. METHODS We surveyed families of children with MH complaints presenting to the emergency department or psychiatry unit who stored firearms in their homes between February 12, 2016, and January 14, 2017. Patients and families received standard care, including routine counseling on limiting access to methods of suicide. Participants completed surveys at baseline, 7, and 30 days after discharge. The primary outcome was triple safe firearm storage-storage of firearms unloaded, locked, and with ammunition stored and locked separately. RESULTS Ninety-one household members of MH patients who stated they had firearms were enrolled at baseline. Seventy-seven (85%) completed at least 1 follow-up survey, and 63 (69%) completed both. At baseline, 21% (19/91) of participants reported engaging in triple safe firearm storage, 26% had an unlocked firearm, 23% had a loaded firearm, and 65% stored ammunition either unlocked or with their firearm. Triple safe storage rates increased to 31% at both 7 days and 30 days. Ten (17%) of 59 (P < 0.01) participants who did not report triple safe storage at baseline and completed a follow-up survey changed to reporting triple safe storage on follow-up. CONCLUSIONS The majority of firearm-storing family members of children with MH complaints do not follow triple safe storage practices. Storage practices modestly improved after an emergent MH visit, but over two thirds of participants reported unsecured or partially secured firearms 7 and 30 days later.

Abstract
BACKGROUND Novel adjuvant strategies are needed to optimise outcomes after complete surgical resection in patients with early-stage non-small-cell lung cancer (NSCLC). We aimed to evaluate adjuvant atezolizumab versus best supportive care after adjuvant platinum-based chemotherapy in these patients. METHODS IMpower010 was a randomised, multicentre, open-label, phase 3 study done at 227 sites in 22 countries and regions. Eligible patients were 18 years or older with completely resected stage IB (tumours ≥4 cm) to IIIA NSCLC per the Union Internationale Contre le Cancer and American Joint Committee on Cancer staging system (7th edition). Patients were randomly assigned (1:1) by a permuted-block method (block size of four) to receive adjuvant atezolizumab (1200 mg every 21 days; for 16 cycles or 1 year) or best supportive care (observation and regular scans for disease recurrence) after adjuvant platinum-based chemotherapy (one to four cycles). The primary endpoint, investigator-assessed disease-free survival, was tested hierarchically first in the stage II-IIIA population subgroup whose tumours expressed PD-L1 on 1% or more of tumour cells (SP263), then all patients in the stage II-IIIA population, and finally the intention-to-treat (ITT) population (stage IB-IIIA). Safety was evaluated in all patients who were randomly assigned and received atezolizumab or best supportive care. IMpower010 is registered with ClinicalTrials.gov, NCT02486718 (active, not recruiting). FINDINGS Between Oct 7, 2015, and Sept 19, 2018, 1280 patients were enrolled after complete resection. 1269 received adjuvant chemotherapy, of whom 1005 patients were eligible for randomisation to atezolizumab (n=507) or best supportive care (n=498); 495 in each group received treatment. After a median follow-up of 32·2 months (IQR 27·4-38·3) in the stage II-IIIA population, atezolizumab treatment improved disease-free survival compared with best supportive care in patients in the stage II-IIIA population whose tumours expressed PD-L1 on 1% or more of tumour cells (HR 0·66; 95% CI 0·50-0·88; p=0·0039) and in all patients in the stage II-IIIA population (0·79; 0·64-0·96; p=0·020). In the ITT population, HR for disease-free survival was 0·81 (0·67-0·99; p=0·040). Atezolizumab-related grade 3 and 4 adverse events occurred in 53 (11%) of 495 patients and grade 5 events in four patients (1%). INTERPRETATION IMpower010 showed a disease-free survival benefit with atezolizumab versus best supportive care after adjuvant chemotherapy in patients with resected stage II-IIIA NSCLC, with pronounced benefit in the subgroup whose tumours expressed PD-L1 on 1% or more of tumour cells, and no new safety signals. Atezolizumab after adjuvant chemotherapy offers a promising treatment option for patients with resected early-stage NSCLC. FUNDING F Hoffmann-La Roche and Genentech.

Receptiveness and Responsiveness Toward Using Social Media for Safe Firearm Storage Outreach: Mixed Methods Study. J Med Internet Res 2021; 23:e24458. [PMID: 34142974 PMCID: PMC8277364 DOI: 10.2196/24458] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 03/19/2021] [Accepted: 03/24/2021] [Indexed: 11/13/2022] Open
Abstract
Background Childhood and adolescent firearm injury and death rates have increased over the past decade and remain major public health concerns in the United States. Safe firearm storage has proven to be an effective measure to prevent firearm injury and death among youth. Social media has been used as an avenue to promote safe firearm storage, but perceptions of this tool remain unknown. Objective The aim of this study was to determine receptiveness and responsiveness in promoting firearm lock box and trigger lock giveaway events on social media, and to describe the characteristics of participants who learned of these events through social media. Methods We performed a mixed methods study combining a content analysis of Facebook event post comments, quantitative analysis of positive and negative feedback on social media, and a descriptive analysis of event participant characteristics. Through a qualitative content analysis approach, we thematically coded comments from each event’s social media page posting. Interrater reliability and κ statistics were calculated. We calculated the prevalence of positive and negative feedback data. Further, we calculated descriptive statistics for demographic characteristics gathered from day-of-event intake surveys. Differences between collected measures were analyzed with χ2 and t tests according to how the participant found out about the event (social media vs other means). Using concurrent analysis, we synthesized the results from both the qualitative and quantitative aims. Results Through qualitative content analysis, 414 comments from 13 events were coded. Seven themes emerged through the comment coding process with the most common being “positive receptiveness” (294/414, 71.0%). From quantitative analysis of the social media content, we found higher levels of positive feedback compared to negative feedback. The average number of event post “likes” was 1271.3 per event, whereas the average count in which “hide post” was clicked was 72.3 times per event. Overall, 35.9% (1457/4054) of participants found out about the event through social media. The participants who learned about the event through social media were on average significantly younger than those who learned about the event through other means (–6.4 years, 95% CI –5.5 to –7.3). Among the group that learned of the event through social media, 43.9% (629/1433) identified as female, whereas 35.5% (860/2420) identified as female among the group that learned of the event through other means. Conclusions There was overall positive receptiveness and responsiveness toward firearm lock box and trigger lock giveaway events when promoted on social media. Compared with other promotional tools, social media has the ability to reach those who are younger and those who identify as female. Future studies should extend this research to determine whether there is a difference between rural and urban settings, and consider other social media platforms in the analysis.

Ultra-Processed Profits: The Political Economy of Countering the Global Spread of Ultra-Processed Foods - A Synthesis Review on the Market and Political Practices of Transnational Food Corporations and Strategic Public Health Responses. Int J Health Policy Manag 2021; 10:968-982. [PMID: 34124866 PMCID: PMC9309965 DOI: 10.34172/ijhpm.2021.45] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Accepted: 04/17/2021] [Indexed: 11/23/2022] Open
Abstract
Background: Ultra-processed food (UPF) and Ultra-processed beverage (UPB) consumption is associated with higher risks of numerous non-communicable diseases (NCDs). Yet global consumption of these products is rising due to profound changes in production, processing, manufacturing, marketing, retail, and consumption practices, alongside the growth of the resources and political influence of Big Food. Whilst the sales of UPFs and UPBs in high-income countries (HICs) are stagnating, sales are rapidly expanding in more populous middle-income countries (MICs). In this paper, we adopt a political economy of food systems approach to understand how growth of Big Food in MICs drives the NCD pandemic.
Methods: We conducted a mixed methods synthesis review. This involved quantitative data collection and development of descriptive statistics; a search for academic, market and grey literature on the expansion of UPF in MICs; and the development of themes, three illustrative case examples (South Africa, Colombia, and Indonesia), and synthesis of the enablers of successful campaigns in MICs into recommendations for public health campaigns.
Results: We project that the combined sales volume of UPFs in MICs will reach equivalency with HICs by 2024, and the total sales volume of UPBs in MICs is already significantly higher than in HICs. Similarly, annual growth in UPF sales is higher in MICs compared to HICs. We also show how Big Food has entrenched its presence within MICs through establishing global production and hyper-local distribution networks, scaling up its marketing, challenging government policies and scientific expertise, and co-opting civil society. We argue that public health can counter the influence of Big Food by developing an expanded global network of driven and passionate people with diverse skillsets, and advocating for increased government leadership.
Conclusion: The projected increase in sales of UPFs and UPBs in MICs raises major concerns about the global capacity to prevent and treat NCDs.

Abstract
8500 Background: Adjuvant platinum-based chemotherapy (chemo) provides only a modest 5-year survival benefit in fully resected, high-risk early-stage NSCLC. We report the primary disease-free survival (DFS) results from the pre-planned interim analysis of IMpower010, a randomized phase 3 open-label trial of adjuvant atezolizumab (atezo; anti–PD-L1) vs best supportive care (BSC) after adjuvant chemo in patients (pts) with early-stage resected NSCLC. Methods: Eligible pts had completely resected (4-12 weeks prior to enrollment) Stage IB (≥4 cm)-IIIA NSCLC (AJCC/UICC v7) and ECOG PS 0-1. A total of 1280 pts were enrolled, and 1269 pts received up to four 21-day cycles of cisplatin-based chemo (plus pemetrexed, docetaxel, gemcitabine or vinorelbine). Of these pts (n=1269), 1005 were subsequently randomized 1:1 to 16 cycles of atezo 1200 mg Q3W or BSC. The primary endpoint of investigator-assessed DFS and secondary endpoint of overall survival (OS) were tested hierarchically: first DFS in the PD-L1 TC ≥1% (SP263) subgroup with Stage II-IIIA disease, then DFS in all randomized pts with Stage II-IIIA disease, then DFS in the ITT population (Stage IB-IIIA) and finally OS in the ITT population. Efficacy assessments were based on randomized pts. Safety was assessed in the safety-evaluable population, defined as pts who received ≥1 dose of atezo or who had ≥1 post-baseline safety assessment if randomized to the BSC arm. Results: At data cutoff (January 21, 2021), median follow-up was 32.2 months in the ITT population. Baseline characteristics were generally balanced between arms. Atezo showed statistically significant DFS benefit vs BSC in the PD-L1 TC ≥1% Stage II-IIIA and all randomized Stage II-IIIA populations; the significance boundary was not crossed for DFS in the ITT population (Table). OS data were immature and not formally tested. Pts in the atezo arm received a median of 16 (range, 1-16) atezo doses. Any-grade AEs occurred in 92.7% (atezo) and 70.7% (BSC); events were Grade 3/4 in 21.8% and 11.5%, respectively. Grade 5 treatment-related AEs occurred in 0.8% of pts in the atezo arm. AEs leading to atezo discontinuation occurred in 18.2% of atezo-treated pts. Conclusions: IMpower010 met its primary endpoint, showing DFS benefit with adjuvant atezo vs BSC after adjuvant chemo in pts with resected Stage II-IIIA NSCLC, with pronounced benefit in the PD-L1 TC ≥1% subgroup. The safety profile of atezo was consistent with prior experience of atezo monotherapy across indications and lines of therapy. Funding: F. Hoffmann-La Roche Ltd.

Adolescent Water Safety Behaviors, Skills, Training and Their Association with Risk-Taking Behaviors and Risk and Protective Factors. CHILDREN-BASEL 2020; 7:children7120301. [PMID: 33348569 PMCID: PMC7765844 DOI: 10.3390/children7120301] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 12/15/2020] [Accepted: 12/15/2020] [Indexed: 11/16/2022]
Abstract
Background: Drowning remains the third leading cause of unintentional injury death for adolescents in the United States. Aims: This study described adolescent swimming lessons, behaviors (life jacket wear while boating) and comfort (swimming in deep water) and their association with protective and risk factors and risk-taking behaviors reported by Washington State students in Grades 8, 10, 12, primarily comprised of youth ages 13 to 18 years. Methods: This study used the 2014 Washington State Healthy Youth Survey (HYS), a publicly available dataset. Results: Most students reported having had swimming lessons, using life jackets, and comfort in deep water. Differences reflected racial, ethnic and socioeconomic disparities: being White or Caucasian, speaking English at home and higher maternal education. Lowest rates of comfort in deep water were among Hispanics or Latino/Latinas followed by Blacks or African Americans. Greater life jacket wear while boating was reported by females, those in lower grades and negatively associated with alcohol consumption, sexual activity and texting while driving. Having had swimming lessons was associated with fewer risk-taking behaviors. Conclusions: The HYS was useful to benchmark and identify factors associated with drowning risk among adolescents. It suggests a need to reframe approaches to promote water safety to adolescents and their families. Multivariate analysis of this data could identify the key determinants amongst the racial, ethnic, and socioeconomic disparities noted and provide stronger estimation of risk-taking and protective behaviors.

Abstract
BACKGROUND The transition to motherhood, although joyous, can be highly stressful, and the availability of professional postpartum support for mothers is often limited. Peer volunteer support programs may offer a viable and cost-effective method to provide community-based support for new mothers. AIM To determine the feasibility of a peer volunteer support program-The Mummy Buddy Program-in which experienced volunteer mothers are paired with, and trained to offer social support to, first-time mothers. METHODS Using a single-group non-randomised feasibility trial, a total of 56 experienced mothers participated in the Mummy Buddy training program, which was focused on education and practical exercises relating to the provision of various forms of social support. Experienced mothers ('Mummy Buddies') were subsequently paired with expectant first-time mothers (n=47 pairs), and were encouraged to provide support until 24-weeks postpartum. FINDINGS In terms of key feasibility considerations, 95.1% of Mummy Buddies felt that they were trained sufficiently to perform their role, and 85.8% of New Mothers were satisfied with the support provided by their Buddy. Analyses of preliminary efficacy (i.e., program outcomes) revealed that the first-time mothers maintained normal levels of stress and depressive symptomology, and possessed relatively strong maternal functioning, across the program duration. CONCLUSION The Mummy Buddy Program appears to be a feasible and potentially valuable peer volunteer support program for first-time mothers. This study provides a foundation for program expansion and for work designed to examine program outcomes-for first-time mothers, Mummy Buddies, and entire family units-within a sufficiently-powered randomised controlled trial.

Abstract
Worldwide, diverse racial/ethnic groups have disproportionately higher drowning rates. Learning to swim and wearing life jackets decrease drowning risk. We evaluated aquatic facilities’ policies regarding use of life jackets, clothing, and diapers through a lens of social justice, equity, and inclusion to ensure they met the needs of the diverse high-risk groups they serve and changing aquatic activities and programs. Public recreational pools, beach and waterpark facilities in the US and international organizations were surveyed regarding their policies on life jacket use, clothing, and diapers between 2015 and 2016. A total of 562 facilities responded, mostly pools. Almost all facilities allowed wearing life jackets in the shallow end but less so in the deep end, and wearing of T-shirts, shorts, and clothes for modesty reasons. Policies varied most on wearing non-swim clothes. Almost universal requirement of diapers applied to infants only. Respondents’ reported themes included cost, access, safety, hygiene and equipment maintenance. Reviewed policies generally reflected facilities’ responsiveness to diverse populations’ specific needs. However, policy variations around wearing clothing and swim diapers could be costly, confusing, and impede participation in aquatic activities by vulnerable populations, specifically young children and racial and ethnic minorities. Standardization of these policies could assist aquatic facilities and their users. A best-practices-based policy is outlined.

Abstract
INTRODUCTION Binge eating may contribute to the prevalence of obesity in African-American women. Yet, there has been scant intervention research on the treatment of binge eating in this population. We tested the feasibility of an appetite awareness training (AAT) intervention in a sample of African-American women with binge and overeating behaviors. Participants who completed AAT were recruited to participate in focus groups to elicit information about their perceptions and experiences with this intervention to inform the design of future interventions to treat binge eating and obesity in African-American women. METHODS African-American women, aged 18-70 years, who had completed an 8-week randomized AAT intervention, were invited to attend a focus group discussion. Session content was recorded and transcribed. Data were analyzed by use of open coding. Themes were identified that described their perceptions and experiences of participating in the intervention. RESULTS Seventeen women participated in three focus group discussions. Pertinent themes identified included: paying attention to internal cues of hunger and satiety, influence of culture on eating patterns, breaking patterns of disordered eating, and perceptions about weight. Overall, participants were satisfied with their experience of AAT, and reported they found it valuable to learn about listening to biological signals of hunger and satiety and to learn specific strategies to reduce maladaptive eating patterns. CONCLUSION AAT was acceptable and provided helpful eating behavior instruction to African-American women with reported binge and overeating behaviors. Future research should examine the potential of AAT to improve weight management in this underserved population. LEVEL OF EVIDENCE Level V, qualitative descriptive study.

Abstract
Safe firearm storage is associated with lower risk of unintentional and intentionally self-inflicted firearm injuries among children and adolescents. Ten community-based firearm safety events were conducted across Washington state from 2015 to 2018. We sought to describe characteristics of event participants and assess whether presence and age of children in the household were associated with household firearm locking practices. We assessed demographic characteristics and baseline firearm storage behaviors of participants using a 13-item survey. Multivariable Poisson regression models were used to estimate prevalence ratios (PR) and corresponding confidence intervals (CI) for the association of presence and age of children in households with prevalence of storing a household firearm unlocked. Of 2956 participants, 58.3% were male and 57.9% lived with an individual under 18 years. Among the 89.8% participants living with firearms, 40.1% stored at least one firearm unlocked and 39.1% stored at least one firearm loaded. In adjusted analyses, there was no statistically significant difference in prevalence of storing a household firearm unlocked between those living with no children (reference group) and those living with a child <11 years (PR = 0.91; 95% CI: 0.80,1.04), or a child aged 11-18 years (PR = 0.94; 95% CI: 0.81,1.09). A high proportion of participants stored a firearm unlocked or loaded at home and neither living with young children nor adolescents was associated with safe locking practices. In comparison with firearm safety interventions conducted in clinic settings, a majority of the participants in these community-based interventions were male and owned firearms.

Abstract
BACKGROUND Although most persons over 5 years of age drown in open water, few laws have sought to regulate open water swim sites. We examined the association between regulations for designated open water swim sites and open water drowning death rates by state. METHODS Using International Classification of Disease (ICD)-10 codes in the CDC Web-based Injury Statistics Query and Reporting System (WISQARS), we identified and calculated open water drowning deaths involving all ages from 2012 to 2017 for 50 states and calculated open water drowning death rates. We then identified and categorised types of state regulations (lifeguards, water quality, rescue equipment, tracking/planning/reporting and signage) for open water swim sites in place in 2017 for a sample of 30 states (20 high-drowning, 10 low-drowning). Analyses evaluated associations between open water drowning rates in three groups (overall, youth and non-white) and the total number and types of state regulations. RESULTS Swim site regulations and open water drowning death rates for 10 839 victims were associated in all regression models. States with more types of regulations had lower open water drowning death rates in a dose-response relationship. States lacking regulations compared with states with all five types of regulations had open water drowning death rates 3.02 times higher among youth (95% CI 1.82 to 4.99) and 4.16 times higher among non-white residents (95% CI 2.46 to 7.05). Lifeguard and tracking/planning/reporting regulations were associated with a 33% and 45% reduction in open water drowning rates overall and among those aged 0-17 years. CONCLUSION States' open water swim area regulations, especially addressing tracking/planning/reporting and lifeguards, were associated with lower open water drowning death rates.

Abstract
Historical data are a valuable resource for addressing present-day conservation issues, for example by informing the establishment of appropriate recovery targets. However, while the recovery of threatened species is the end goal of many conservation programmes, data made available through the efforts of palaeoecologists and historical ecologists are rarely consulted. The proposal of a 'Green List of Species' by the International Union for Conservation of Nature (IUCN) will soon change this. The Green List of Species measures recovery against historical baselines; in particular, the method requires estimates of species range and abundance in previous centuries. In this paper, we present the case for why setting species recovery against a historical baseline is necessary to produce ambitious conservation targets, and we highlight examples from palaeoecology and historical ecology where fossil and archival data have been used to establish historical species baselines. Finally, we introduce Conservation Archive (https://conservationarchive.shinyapps.io/ConservationArchive/), a database of resources that can be used to infer baseline species conditions, and invite contributions to this database. This article is part of a discussion meeting issue 'The past is a foreign country: how much can the fossil record actually inform conservation?'

Abstract
Introduction Safe firearm storage is associated with a lower risk of firearm-related injury and death. Although providing firearm locking devices is a key component of firearm safety interventions, little is known about the types and characteristics of devices preferred by firearm users or others who make decisions about firearm storage. The aim of this study was to describe preferences for firearm locking devices and device features among firearm safety event participants. Methods We conducted a cross-sectional survey in the State of Washington in 2016 that assessed participants’ preferences for five firearm locking devices (eg, trigger lock) and seven device features (eg, quick access). We categorized respondents (n=401) as adults in households with 1) all firearms locked, 2) at least one unlocked firearm, and 3) no firearms. We analyzed data in 2017. Results Device ownership and feature preferences varied substantially but were similar across the three household categories. Of those residing with unlocked firearms, 84% reported they would consider using or definitely use a lock box, whereas 11% reported they would never use a trigger lock. Additionally, of those residing with unlocked firearms, 80% and 89% reported that the ability to lock a firearm while loaded and unlock it quickly were, respectively, “very important” or “absolutely essential.” Conclusion Participants had differing preferences for firearm locking devices and device features, although preferences were largely similar across households with locked, unlocked, or no firearms. At least eight in ten participants reported “great importance” regarding the ability to lock a firearm while loaded and unlock it quickly, which is likely related to perceptions about the utility of safely stored firearms for household protection. Designing firearm safety interventions to match the needs and preferences of those who make firearm storage decisions may improve their effectiveness.

Abstract
It is increasingly accepted that survival alone is an inadequate measure of the success of childhood brain tumour treatments. Consequently, there is growing emphasis on capturing quality of survival. Ependymomas are the third most frequently occurring brain tumours in childhood and present significant clinical challenges. European Society of Paediatric Oncology Ependymoma II is a comprehensive international program aiming to evaluate outcomes under different treatment regimens and improve diagnostic accuracy. Importantly, there has been agreement to lower the age at which children with posterior fossa ependymoma undergo focal irradiation from three years to either eighteen months or one year of age. Hitherto radiotherapy in Europe had been reserved for children over three years due to concerns over adverse cognitive outcomes following irradiation of the developing brain. There is therefore a duty of care to include longitudinal cognitive follow-up and this has been agreed as an essential trial outcome. Discussions between representatives of 18 participating European countries over 10 years have yielded European consensus for an internationally accepted test battery for follow-up of childhood ependymoma survivors. The 'Core-Plus' model incorporates a two-tier approach to assessment by specifying core tests to establish a minimum dataset where resources are limited, whilst maintaining scope for comprehensive assessment where feasible. The challenges leading to the development of the Core-Plus model are presented alongside learning from the initial stages of the trial. We propose that this model could provide a solution for future international trials addressing both childhood brain tumours and other conditions associated with cognitive morbidity.

Clinical developmental, neuropsychological, and social-emotional features of Turner syndrome. AMERICAN JOURNAL OF MEDICAL GENETICS PART C-SEMINARS IN MEDICAL GENETICS 2019; 181:126-134. [PMID: 30767374 DOI: 10.1002/ajmg.c.31687] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 01/16/2019] [Accepted: 01/17/2019] [Indexed: 12/11/2022]
Abstract
Individuals with Turner syndrome (TS) are at risk for a constellation of neurocognitive and psychosocial differences, although there is significant individual variability in these features. TS is associated with an increased risk for difficulties with visual-spatial reasoning, visual-spatial memory, attention, executive functioning, motor, and math skills. Additionally, increased rates of social difficulties, anxiety, and depression are observed. There can be significant interplay between all of these factors contributing to the behavioral phenotype. Neuropsychological features and previous research are reviewed. Clinical considerations and recommendations for evaluation and treatment of psychological and behavioral difficulties are provided, including consideration of medical features in TS, as well as therapies, educational supports, and medication treatment. Future research is needed to evaluate effectiveness of different treatments for neuropsychological and psychosocial features of TS, including modification and validation of existing evidence-based treatments and new approaches to care.

Abstract
Introduction Hepatitis C virus (HCV) infection prevalence is believed to be elevated in Punjab, India; however, state-wide prevalence data are not available. An understanding of HCV prevalence, risk factors and genotype distribution can be used to plan control measures in Punjab. Methods A cross-sectional, state-wide, population-based serosurvey using a multi-stage stratified cluster sampling design was conducted October 2013 to April 2014. Children aged ≥5 years and adults were eligible to participate. Demographic and risk behavior data were collected, and serologic specimens were obtained and tested for anti-HCV antibody, HCV Ribonucleic acid (RNA) on anti-HCV positive samples, and HCV genotype. Prevalence estimates and adjusted odds ratios for risk factors were calculated from weighted data and stratified by urban/rural residence. Results 5,543 individuals participated in the study with an overall weighted anti-HCV prevalence of 3.6% (95% Confidence Interval [CI]: 3.0%–4.2%) and chronic infection (HCV Ribonucleic acid test positive) of 2.6% (95% CI: 2.0%–3.1%). Anti-HCV was associated with being male (adjusted odds ratio 1.52; 95% CI: 1.08–2.14), living in a rural area (adjusted odds ratio 2.53; 95% CI: 1.62–3.95) and was most strongly associated with those aged 40–49 (adjusted odds ratio 40–49 vs. 19–29-year-olds 3.41; 95% CI: 1.90–6.11). Anti-HCV prevalence increased with each blood transfusion received (adjusted odds ratio 1.36; 95% CI: 1.10–1.68) and decreased with increasing education, (adjusted odds ratio 0.37 for graduate-level vs. primary school/no education; 95% CI: 0.16–0.82). Genotype 3 (58%) was most common among infected individuals. Discussion The study findings, including the overall prevalence of chronic HCV infection, associated risk factors and demographic characteristics, and genotype distribution can guide prevention and control efforts, including treatment provision. In addition to high-risk populations, efforts targeting rural areas and adults aged ≥40 would be the most effective for identifying infected individuals.

Abstract
OBJECTIVES To characterise sex differences in macronutrient intakes and adherence to dietary recommendations in the UK Biobank population. DESIGN Cross-sectional population-based study. SETTING UK Biobank Resource. PARTICIPANTS 210 106 (52.5% women) individuals with data on dietary behaviour. MAIN OUTCOME MEASURES Women-to-men mean differences in nutrient intake in grams and as a percentage of energy and women-to-men ORs in non-adherence, adjusting for age, socioeconomic status and ethnicity. RESULTS There were sex differences in energy intake and distribution. Men had greater intakes of energy and were less likely to have energy intakes above the estimated average requirement compared with women. Small, but significant, sex differences were found in the intakes of all macronutrients. For all macronutrients, men had greater absolute intakes while women had greater intakes as a percentage of energy. Women were more likely to have intakes that exceeded recommendations for total fat, saturated fat and total sugar. Men were less likely to achieve the minimum recommended intakes for protein, polyunsaturated fat and total carbohydrate. Over 95% of men and women were non-adherent to fibre recommendations. Sex differences in dietary intakes were moderated by age and to some extent by socioeconomic status. CONCLUSIONS There are significant sex differences in adherence to dietary recommendations, particularly for sugar. However, given the increased focus on food groups and dietary patterns for nutritional policy, these differences alone may not be sufficient for policy and health promotion. Future studies that are able to explore the sex differences in intakes of different food groups that are risk factors for diet-related diseases are warranted to improve the current understanding of the differential impact of diet on health in women and men.

Abstract
BACKGROUND Safe firearm storage practices are associated with a lower risk of unintentional and self-inflicted firearm injuries among household members, though many firearms remain unlocked and/or loaded. OBJECTIVES Conduct a preliminary evaluation of a community-based firearm safety intervention and assess participants' preferences for firearm locking devices and their comfort with potential firearm safety counsellors. DESIGN/METHODS Baseline event and follow-up surveys among adult participants to assess changes in firearm storage practices, including whether all household firearms were stored locked, all were unloaded, all ammunition was locked, and a composite measure assessing whether all firearms were locked and unloaded and all ammunition was stored locked. RESULTS A total of 206 out of 415 participants completed both surveys and were included. Nearly 9 in 10 respondents preferred the firearm lock box rather than a trigger lock. At follow-up, a significantly greater proportion reported that all household firearms were locked (+13.7%) and unloaded (+8.5%) and a non-significantly greater proportion reported that all ammunition was locked (+6.3%). A significantly greater proportion reported practising all three safe firearm and ammunition storage practices at follow-up (+12.6%). A majority reported they would be comfortable or very comfortable discussing firearm safety with various safety counsellors, though women were less likely to do so than men. CONCLUSION This intervention that included distribution of a free, participant-selected locking device improved safe firearm storage practices among participants. Differences in participant preferences for devices and safety counsellors suggest that a 'one size fits all' approach may be inadequate in affecting population-level storage practices.

Abstract
Most fatal drownings worldwide occur in open water. Flotation devices may protect swimmers. Their use by those recreating in water has not been described. METHODS Observational survey of swimmers and waders at designated swim sites at lakes and rivers evaluated them by age group, sex, type of flotation used (life jacket vs substandard flotation, eg, water wings, noodles, inflatables) and, for children <6 years, being within arm's reach of an adult. RESULTS Of 1967 swimmers/waders observed, 37% used some type of flotation device. Use rates, especially of life jackets, decreased with increasing age. Children <6 years had the highest use of some type of flotation (140/212, 66%) and the highest use of life jackets (50.5%). Children <13 years were more likely to use flotation devices and life jackets than teens (RR 6.78, 3.62 to 12.71); boys were more likely than girls to wear life jackets (RR 1.47, 1.18 to 1.83). While teenagers and adults used flotation (29.5% and 23.5%), they rarely used life jackets (2-3%). Boys <6 years who were further than arm's length of an adult were more likely to wear life jackets than girls. Substandard flotation use did not differ among age groups (15.5-26.5%) but their use was greater among females in most age groups. CONCLUSIONS Flotation devices were frequently used for recreational wading and swimming in open water by all age groups. Life jacket use was limited to children. Promoting use of flotation devices with safety standards that provide protection as well as fun could potentially decrease open water drowning rates.

Abstract
INTRODUCTION The Australian Aboriginal population experiences significantly poorer health than the non-Aboriginal population. The contribution of environmental risk factors in remote communities to this health disparity is poorly understood. OBJECTIVE To describe and quantify major environmental risk factors and associated health outcomes in remote Aboriginal communities in Western Australia. METHODS The association between environmental health indicators, community infrastructure and reported health outcomes was analysed using linear and logistic regression of survey data. RESULTS Housing/overcrowding was significantly associated with increased reports of hearing/eyesight (OR 3.01 95 % CI 1.58-5.73), skin (OR 2.71 95 % CI 1.31-5.60), gastrointestinal (OR 3.51 95 % CI 1.49-8.26) and flu/colds (OR 2.47 95 % CI 1.27-4.78) as health concerns. Dust was significantly associated with hearing/eyesight (OR 3.16 95 % CI 1.82-5.48), asthma/respiratory (OR 2.48 95 % CI 1.43-4.29) and flu/colds (OR 3.31 95 % CI 1.88-5.86) as health concerns. CONCLUSION Poor environmental health is prevalent in remote Aboriginal communities and requires further delineation to inform environmental health policy.

Abstract
OBJECTIVE In contrast to previous clinical practice, current guidelines recommend bilateral cochlear implantation in children, resulting in a cohort of children who initially received one implant, but have subsequently had a second, contralateral implant. This study aimed to explore satisfaction and quality of life in children implanted simultaneously or sequentially. DESIGN A novel measure of satisfaction and quality of life following paediatric bilateral cochlear implantation (the Brief Assessment of Parental Perception; BAPP) was developed and preliminary validation undertaken as part of a large, national project of bilateral implantation. Children's parents completed the measure yearly for up to three years following implantation. STUDY SAMPLE Children from 14 UK implant centres were recruited into the study; data were available for 410 children one year post-implantation. RESULTS The BAPP was found to have good face and convergent validity, and internal consistency. Results indicated very high levels of satisfaction with the devices, and improvements in quality of life. However there was evidence that children implanted sequentially were less willing to wear their second implant in the first two years than those children receiving simultaneous implants. CONCLUSION Simultaneous and sequential cochlear implants have a positive impact on the quality of life of deaf children.

Abstract
BACKGROUND Drowning is the second leading cause of unintentional injury death among US children. Multiple studies describe decreased drowning risk among children possessing some swim skills. Current surveillance for this protective factor is self/proxy-reported swim skill rather than observed inwater performance; however, children's self-report or parents' proxy report of swim skill has not been validated. This is the first US study to evaluate whether children or parents can validly report a child's swim skill. It also explores which swim skill survey measure(s) correlate with children's inwater swim performance. METHODS For this cross-sectional convenience-based sample, pilot study, child/parent dyads (N=482) were recruited at three outdoor public pools in Washington State. Agreement between measures of self-reports and parental-reports of children's swim skill was assessed via paired analyses, and validated by inwater swim test results. RESULTS Participants were representative of pool's patrons (ie, non-Hispanic White, highly educated, high income). There was agreement in child/parent dyads' reports of the following child swim skill measures: 'ever taken swim lessons', perceived 'good swim skills' and 'comfort in water over head'. Correlation analyses suggest that reported 'good swim skills' was the best survey measure to assess a child's swim skill-best if the parent was the informant (r=0.25-0.47). History of swim lessons was not significantly correlated with passing the swim test. CONCLUSIONS Reported 'good swim skills' was most correlated with observed swim skill. Reporting 'yes' to 'ever taken swim lessons' did not correlate with swim skill. While non-generalisable, findings can help inform future studies.

Abstract
Long-term outcomes and updated clinical efficacy and safety data were evaluated for newly-diagnosed multiple myeloma patients treated on a phase II study of bortezomib and pegylated liposomal doxorubicin (PegLD). Out of 61 patients, the overall response rate was 57% and the near-complete/complete response rate was 7%. Patients aged ≥65 years old had a higher incidence of treatment-related ≥Grade 3 non-haematological toxicity (80% vs. 51%, P = 0·020). Median overall survival was 5·6 years and negatively impacted by the presence of International Staging System stage III disease, underscoring the need for novel treatment strategies for this group of patients.
