Consumers' experiences, preferences, and perceptions of effectiveness in using telehealth for cancer care in Australia. Asia Pac J Clin Oncol 2023; 19:752-761. [PMID: 37712136 DOI: 10.1111/ajco.14002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 08/06/2023] [Accepted: 08/27/2023] [Indexed: 09/16/2023]
Abstract
AIM COVID-19 accelerated telehealth (video and telephone) use for cancer care to reduce disease exposure and transmission. Understanding consumers' health service delivery needs is required to sustain telehealth activity and develop new models of care. We explored consumers' experiences of telehealth in cancer care and their perspectives on improving and sustaining telehealth uptake in the future. METHODS Exploratory design mixed-methods study using the Model for Assessment of Telemedicine (MAST) framework. Consumers affected by cancer completed an online survey and semistructured interviews. Quantitative data were analyzed using descriptive statistics and chi-square. Qualitative data from the MAST consumer domain were thematically analyzed. RESULTS There were 1162 survey respondents and 18 interview participants. Video and telephone were used in cancer care with various providers. Telephone was used more frequently. Most respondents (85%) had reliable internet connections for video, however, 36% were not offered a video consultation. Video compared with telephone users were statistically significantly more likely to be satisfied with the quality of their treatment and perceived their consultation achieved as much as an in-person consultation. Telephone users (51%) compared with video users (31%) were more likely to perceive their concerns would have been better understood by their care provider if they were seen in person. Five themes emerged from the qualitative data. Consumers want modality choice, video provides superior experiences versus telephone, consultation mode preference is fluid, and consultation scheduling and administration need further consideration. CONCLUSION Consumers support telehealth in cancer care. Consumers want consultation mode choices based on their needs and purpose of consultation.

Abstract
PURPOSE/OBJECTIVE(S) The optimal delivery of postoperative radiotherapy to WHO grade 2 or atypical meningiomas (AM) is controversial. The historical standard of care has been high dose fractionated radiation to the resection bed and a 2 cm CTV as in RTOG 0539. Single fraction radiosurgery offers a more conformal alternative with demonstrated local control for smaller AM in less sensitive areas. Though less studied, fractionated stereotactic radiosurgery (FSRT) promises safer treatment of larger AM in more sensitive locations while minimizing the treated volume. This single institution retrospective review examines the hypothesis that local and marginal failure patterns in AM treated with five fraction FSRT remain unacceptably high. MATERIALS/METHODS Thirty-nine patients received 27.5 - 30 Gy in 5 fractions to their AM from 2009 to 2022 with grading based on the WHO criteria active at the time of treatment. All treatments were frameless VMAT deliveries with no PTV margin. Histological diagnosis of AM, gross disease at time of FSRT, five fraction FSRT, and lack of prior local radiation were required for inclusion. Single fraction treatments were excluded. Local recurrence was defined similar to RECIST criteria as an increase of 20% in the greatest cross-sectional diameter on MRI (or CT if MRI contraindicated) with at least one voxel touching the prescription volume. To examine the role of CTV margin, marginal recurrence was defined as any new lesion outside of the prescription volume but within 2 cm of the resection cavity. High grade toxicity per CTCAE v5 was an irreversible grade 3 or any grade 4 toxicity. Resection for radionecrosis was considered a local failure if any viable tumor was seen on pathology. RESULTS Median follow up was 32.5 months (range 3.2-147.5 months). The number of AM treated post STR, post GTR recurrence, and definitively were 26, 16, and 5 respectively. 3-year local tumor control was estimated to be 84%. As expected, larger tumors were more likely to fail locally (p >.001). Two (5%) patients experienced high grade toxicity - both symptomatic radionecrosis requiring resection. Three-year marginal control was estimated to be 92.3%. Of the 5 tumors treated to the entire resection cavity, none experienced a marginal failure. Interestingly, recurrent tumors s/p GTR were more likely to recur marginally than tumors treated after STR (p = .009). Only 1 (4%) tumor treated after STR failed marginally while 4 (33%) tumors treated after GTR recurrence failed. CONCLUSION The rate of high-grade toxicity in AM receiving FSRT was low. Local control appeared comparable to historical rates which may suggest the need for dose escalation with longer term follow-up. Recurrent tumors appear more prone to marginal failures, however more work is needed to determine which patients may benefit from additional CTV margin and more prolonged fractionated dose schedules. Improved targeting with newer imaging studies (e.g., DOTATATE PET) should be examined to determine if more accurate targeting will improve outcomes.

Land use modification causes slow, but predictable, change in soil microbial community composition and functional potential. ENVIRONMENTAL MICROBIOME 2023; 18:30. [PMID: 37024971 PMCID: PMC10080853 DOI: 10.1186/s40793-023-00485-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 03/19/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND Bacterial communities are critical to ecosystem functioning and sensitive to their surrounding physiochemical environment. However, the impact of land use change on microbial communities remains understudied. We used 16S rRNA gene amplicon sequencing and shotgun metagenomics to assess soil microbial communities' taxonomic and functional responses to land use change. We compared data from long-term grassland, exotic forest and horticulture reference sites to data from sites that transitioned from (i) Grassland to exotic forest or horticulture and from (ii) Exotic forest to grassland. RESULTS Community taxonomic and functional profiles of the transitional sites significantly differed from those within reference sites representing both their historic and current land uses (P < 0.001). The bacterial communities in sites that transitioned more recently were compositionally more similar to those representing their historic land uses. In contrast, the composition of communities from sites exposed to older conversion events had shifted towards the compositions at reference sites representing their current land use. CONCLUSIONS Our study indicates that microbial communities respond in a somewhat predictable way after a land use conversion event by shifting from communities reflecting their former land use towards those reflecting their current land use. Our findings help us to better understand the legacy effects of land use change on soil microbial communities and implications for their role in soil health and ecosystem functioning. Understanding the responsiveness of microbial communities to environmental disturbances will aid us in incorporating biotic variables into soil health monitoring techniques in the future.

Abstract
INTRODUCTION Appendicitis continues to be a common surgical emergency in children, but its diagnosis remains challenging. Use of diagnostic imaging to confirm appendicitis has gained popularity in some countries because it is associated with lower negative appendicectomy rates. This study reports our centre's experience of adopting routine ultrasound for the investigation of suspected appendicitis in children. METHODS A single-centre retrospective cohort study was performed investigating all children aged 5-16 years admitted under surgeons with suspected appendicitis, in January-December 2019. Primary outcomes were the rate of ultrasound use, its accuracy in diagnosing/excluding appendicitis and negative appendicectomy rate. Other outcomes were treatment received, length of stay and complications. RESULTS The majority of the 193 children with suspected appendicitis underwent a diagnostic ultrasound (87.5%). Ultrasound was highly sensitive (0.90, 95% confidence interval (CI) 0.81-0.96) and specific (1.0, 95% CI 0.96-1.0) for appendicitis in this study. Negative appendicectomy rate was extremely low (1.4%). Laparoscopic appendicectomy was the preferred management (75/86), with one case started open and no conversions to open. A minority of cases of simple appendicitis (10/86) were treated primarily with antibiotics. Rates of complex appendicitis and postoperative complications were similar to other studies. CONCLUSION Ultrasound can be highly sensitive and specific for appendicitis. Its routine use to confirm appendicitis prior to surgery is associated with a low negative appendicectomy rate. This is a major change in practice for a general surgical unit in the United Kingdom.

Prognostic prediction of genotype versus phenotype in genetic cardiomyopathies. Eur Heart J 2022.

Abstract
Abstract
Background
In cardiomyopathies (CMPs), the diverse genetic background often leads to phenotypic heterogeneity. Currently, genotype-phenotype studies are founded on clinical phenotype-based classification of CMPs, contributing possible biases due to the exclusion of specific and unascertained phenotypic expressions of CMP genes.
Purpose
We sought to define differences in outcome when stratifying patients based on phenotype at presentation compared with genotype in a large cohort of CMP patients with positive genetic testing.
Methods
In this study, we included the whole spectrum of non-hypertrophic CMP phenotypes, genetically determined: dilated cardiomyopathy (DCM), arrhythmogenic right ventricular cardiomyopathy (ARVC), left ventricular arrhythmogenic cardiomyopathy (ALVC) and biventricular ARVC (BiV). The primary and secondary outcomes were: 1) all-cause mortality/heart transplant (D/HT); 2) heart failure-related death/heart transplant/left ventricular assist device implantation (DHF/HT/VAD); and 3) sudden cardiac death/life-threatening ventricular arrhythmias (SCD/MVA).
Results
Two hundred and eighty-one patients (80% DCM) carrying pathogenic or likely pathogenic variants were included in this study. The phenotype was classified as DCM, ARVC, ALVC and BiV according to current consensus criteria. The median follow-up was 188 months. Variants in titin (TTN; 34%) and sarcomeric genes (SARC; 22%) were the most frequent genotypes and almost invariably associated with a DCM phenotype. DSP, LMNA and FLNC displayed more heterogeneous phenotypic presentations, including DCM, ARVC, ALVC, BiV. At survival analysis, the arrhythmic outcome occurred more frequently in patients without a DCM phenotype and in carriers of DSP, PKP2, LMNA and FLNC variants. However, after adjustment for age and sex, the genotype-based classification but not the phenotype-based classification was predictive of the arrhythmic outcome. LMNA showed the worst trend in term of D/HT and DHF/HT/LVAD.
Conclusions
In genetic cardiomyopathies, genotype is associated with significant phenotypic heterogeneity. Nevertheless, in our study, the genotypic-based classification showed higher precision in predicting CMP patients' outcome in respect to the phenotype-based classification. These findings add to the current understanding of inherited CMPs and may implement the risk stratification of patients with positive genetic testing.

Injectable carbon nanotube-functionalized hydrogel as a tool for cardiac tissue engineering. Eur Heart J 2022.

Abstract
Abstract
Background/Introduction
Heart failure (HF) is an expensive major public health problem in the United States and around the world (1). The current treatments for HF are aimed at reducing symptoms, slowing disease progression, and reducing mortality and not aimed at repairing heart muscle or restoring function. Furthermore, even with these treatments, approximately half of patients with HF will die within 5 years of diagnosis (2). Cardiac transplantation remains the only definitive treatment for those affected with end-stage HF, but availability of donor hearts remains a major limitation (3).
Purpose
The ability of the adult heart to regenerate cardiomyocytes (CMs) lost after injury is limited, generating interest in developing tissue engineering therapies to avoid progression towards HF. Rigid carbon nanotubes (CNTs) scaffolds have been used to improve CMs viability, proliferation, and maturation (4), but require undesirable invasive surgeries for implantation. To overcome this limitation, we engineered an injectable reverse thermal gel (RTG) functionalized with CNTs (RTG-CNT) that transitions from a liquid-solution to a gel-based matrix shortly after reaching body temperature allowing for a liquid-based delivery rapidly followed by a stable-gel localization (5).
Methods and results
Here we show experimental evidences the RTG-CNT hydrogel, used as a three-dimensional (3D) niche to culture human induced pluripotent stem cells (hiPSC)-CMs, promotes hiPSC-CMs alignment and elongation with increased Cx43 localization and improved contraction function when compared with traditional two-dimensional (2D) fibronectin controls and plain 3D RTG system without CNTs. Moreover, the short-term (4-week) biocompatibility of the RTG-CNT hydrogel was also assessed in a mouse model (intracardial injection). The results confirmed that the RTG-CNT hydrogel is well tolerated by the cardiac tissue.
Conclusion
Our results indicated that the injectable RTG-CNT hydrogel has the potential to be used as a minimally invasive tool for cardiac tissue engineering efforts.

Abstract
Abstract
Purpose: Assess the feasibility of measuring Repetitive Head Impacts (RHI), cognition, and eye movements across a single season of high school football. Methods: Twelve players were provided an instrumented mouthguard (3200 Hz; Prevent Biometrics, Edina, MA) to evaluate RHI. Mouthguard use was assessed by total impacts and number of games/practices. Seven players also agreed to complete cognitive (ImPACT) and custom eye-tracking (500 Hz; EyeLink II) assessments pre-, mid-, and post-season. Multiple repeated measure ANOVA’s were completed using standard composite scores for ImPACT and oculomotor metrics. Results: Fifty percent of players ever used their mouthguard, and substantial variability in total impacts (M = 86.5, SD = 98.0, Range = 7–277) and number of games/practices (M = 9.8, SD = 7.6, Range = 2–23) were observed among players who did use their mouthguard. Specific completion rates for the 3 cognitive and 3 eye-tracking assessments were 71% each, and 57% of players completed all 6 scheduled assessments. Repeated measures ANOVA indicated Visual Motor Speed (VMS) improved between assessments (p = 0.015). Post hoc analysis showed both VMS and Verbal Memory increased from pre- to mid-season (−5.30(95%CI, −10.47 to −0.12), p = 0.046), (−0.20(95%CI, −13.00 to −1.41), p = 0.024). Conclusions: Variability in mouthguard use and missing assessment rates represent practical challenges in prospectively measuring RHI and utilizing multiple longitudinal assessment methods in high school football players. Although ImPACT results should be interpreted cautiously, future research should consider the potential role of practice effects and/or intentionally poor pre-season effort to explain the increase in performance during the season. A larger sample size will increase the possibility of measuring the effect of RHI on assessment outcomes.

Background
Rhythmia HDx® is a novel ultra-high density electroanatomical mapping system using an innovative 64 electrode basket catheter. A learning curve is a recognised phenomenon for any new technology and was examined in this study.
Purpose
Comparison of performance, long-term success, and complications using Rhythmia for atrial ablation in the UK.
Methods
Retrospective data collection from three centres across the UK from the introduction of Rhythmia. Patients were matched with controls who had undergone ablation using the well-established Carto3 mapping system. Assessed were: fluoroscopy, radiofrequency ablation and procedure times; acute and long term success, and complications.
Results
253 study patients with 253 controls were included. Significant correlations existed between procedural efficiency metrics and centre experience for de novo atrial fibrillation (AF) ablation (procedure time, Spearman’s ρ = -0.624; ablation time, ρ = -0.795), and de novo atrial flutter (AFlut) ablation (ablation time, ρ = -0.566; fluoroscopy time, ρ = -0.520). No such correlations existed for redo AF, redo AFlut, de novo atrial tachycardia (AT), or redo AT cases. For de novo AF and AFlut, procedural efficiency metrics were significantly improved after 10 procedures in each centre, (procedure time [AF only, p = 0.001], ablation time [AF, p < 0.0005; AFlut p < 0.0005] and fluoroscopy time [AFlut only, p = 0.0022]), and became comparable to controls (Figures 1 and 2). Acute success and long-term success did not see significant improvement with experience but were comparable to the control group. There was no relationship between experience and complications, which were comparable to Carto3 (3.6% in both groups).
Conclusion
A short learning curve exists with the use of Rhythmia HDx for standardised procedures (de novo AF / AFlut). Procedural performance improves and becomes comparable to Carto3 following 10 cases at each centre. Clinical outcomes at 6 and 12 months, and complications are not affected by this learning curve and remain comparable with controls.

Abstract
BACKGROUND Risk of breast cancer in adult life is influenced by body size and height in childhood, but the mechanisms responsible for these associations are currently unknown. We carried out research to determine if, at age 15-18, measures of dietary intake were associated with body size, hormones, and with variations in breast tissue composition that in adult life are associated with risk of breast cancer. METHODS In a cross-sectional study of 766 healthy Caucasian women aged 15-18, we measured percent breast water (PBW), total breast water and fat by magnetic resonance (MR), and assessed dietary intake using a validated food frequency questionnaire. We also measured height, weight, skin-fold thicknesses and waist-to-hip ratio, and in fasting blood assayed glucose and insulin. RESULTS After adjustment for age, measures of body size, and energy intake, dietary fiber (insoluble and total fiber) and insulin were associated positively and significantly with PBW. CONCLUSIONS Dietary fiber and fasting insulin were associated with breast tissue measures. These data suggest a potential approach to breast cancer prevention.

Abstract
Telehealth can effectively increase access to specialist care and reduce the need for travel. The Geri-Connect service was established in 2017 to support people living in residential aged care facilities in regional Victoria, Australia. Using the Model for the Assessment of Telemedicine, an evaluation of the Geri-Connect service identified service activity patterns and factors associated with uptake. Service activity from 2017 to 2020 and 10 semi-structured, key stakeholder interviews were captured and analysed. Between 2017 and 2020, video consultations were provided to 53 residential aged care facilities. Sustained growth (over 178%) and strong stakeholder acceptance highlight the effectiveness of this telegeriatric service. Four recommendations provide opportunities to further enhance service delivery including: implementation of an integrated health information system; systematic evaluation of service impact on stakeholders and residents, auditing and subsequent provision of targeted training; and regular auditing of software and hardware. Additionally, the need to augment fixed room hardware with mobile telehealth systems would increase access for residents with mobility problems. Dedicated personnel of the centralised team are best suited to implementing the recommendations. Whilst the provision of routine telehealth services into residential aged care facilities is challenging, the Geri-Connect service demonstrates that telehealth can be effectively provided to residential aged care facility residents needing specialist geriatric care.

Systematic review: Acculturation strategies and their impact on the mental health of migrant populations. PUBLIC HEALTH IN PRACTICE 2021; 2:100069. [PMID: 36101596 PMCID: PMC9461568 DOI: 10.1016/j.puhip.2020.100069] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 11/14/2020] [Accepted: 12/06/2020] [Indexed: 11/17/2022] Open
Abstract
Objectives This study aims to examine the correlation between the different types of migrant acculturation strategies according to Berry’s model of acculturation (integration, assimilation, separation, and marginalisation) and their effects on mental health conditions, such as depression, anxiety and PTSD. Study design Systematic Review. Methods Three databases (PubMed, Ovid and Ebsco) were searched using different combinations of search terms to identify relevant articles to be included. The search terms were pre-identified using relevant synonyms for “migrants”, “mental health” and “integration”. The list of article titles from these searches were then filtered using predefined inclusion and exclusion criteria. The mental health consequences included a range of common conditions including suicide/self-harm, depressive disorders, psychosis, as well as substance misuse. Results 21 primary studies were included in the review, which assessed 61,885 migrants in total (Fig. 1 and Supplemental File 1). Of these, seven were cohort studies and fourteen were cross-sectional studies. Most studies showed that marginalisation was associated with worse depression symptoms, compared to integration, assimilation and separation, while integration was associated with the least depressive symptoms. Marginalisation more than triples the likelihood of anxiety-related symptoms compared to integration. Similarly, separation increased the likelihood of anxiety-related symptoms nearly six-fold. Conclusions Our review found out that marginalisation had the worst effects on mental health of the migrant populations while integration had the most positive effects. The study also identified three key sources which may contribute to acculturation stress and worse mental health: low education or skill set, proficiency of the host country’s language, and financial hardships.

Acne and rosacea in skin of colour. Clin Exp Dermatol 2021; 47:259-263.

Abstract
Acne and rosacea are common inflammatory skin conditions present in numerous racial and ethnic groups. There are distinct differences in clinical presentation, exacerbating factors, potential triggers and consequences of both conditions in individuals with skin of colour (SOC), classified as Fitzpatrick skin types III-VI. For example, acne can be complicated by the development of postinflammatory hyperpigmentation and keloid scarring in SOC, and this can influence treatment choice. Although rosacea is reported less frequently in SOC, this may be the result of delayed diagnosis or late presentation due to the difficulty in discerning the classic features of erythema in darker skin tones. In such cases, additional clues in the medical history and clinical examination may assist in making the diagnosis. This review aims to summarize nuances in both the diagnosis and management of these two common skin conditions in patients with SOC to support clinicians in providing an individualized treatment approach.

Our study has also identified 16 factors that negatively impact level of migrant acculturation, 19 factors that adversely impact general mental health of migrants, and 22 factors that increases risks of depressive symptoms in migrants.
Conclusions
Our review found out that marginalisation had the worst effects on migrant mental health while integration had the most positive effects. The study also established multiple factors associated with low levels of acculturation and poor mental health in migrants. Given the problem of limited public resources, governments can identify at-risk individuals using factors highlighted and channel these scarce resources to develop targeted mental health interventions for them.

Background
Remote patient monitoring (RPM) is an underutilised telehealth intervention that can enhance self-management of cardiovascular and pulmonary disease and reduce acute care use. However, studies of effectiveness of RPM interventions vary widely. This study aimed to explain the variation in outcomes related to RPM interventions within cardiac and pulmonary populations. Specifically, we aimed to answer why some RPM interventions are more successful than others in reducing demand on acute care services.
Methods
In brief, search terms for remote monitoring and acute care utilisation were used across three electronic databases: PubMed, EMBASE and CINAHL. The search, conducted in October 2020, included articles published in the last five years (2015-2020). Articles were included if they used RPM to monitor an individual’s biometrics (e.g. heart rate, blood pressure) from a distance while they are not in hospital. Realist review methodology was used to enable exploration of how, why and for whom interventions do and do not work. Outcomes were evaluated to determine contextual factors and potential mechanisms that led to variation in cardiac and pulmonary intervention outcomes.
Results
After screening, 91 articles met the eligibility criteria and were included. We found that across a broad range of RPM interventions 31 factors emerged that are likely to impact the effectiveness of cardiac and pulmonary RPM innovations. These were synthesised into six theories of intervention success: 1) targeting populations at high risk; 2) accurately detecting a decline in health; 3) providing responsive and timely care; 4) personalising care; 5) enhancing self-management and, 6) ensuring collaborative and coordinated care.
Conclusion
While RPM interventions are complex, if they are designed with patients, providers and the implementation setting in mind and with the key variables identified within this review incorporated, it is more likely that they will be effective at reducing acute hospital events.

Abstract
L3-HAPLS (High-repetition-rate Advanced Petawatt Laser System) at ELI (Extreme Light Infrastructure) Beamlines currently delivers 0.45 PW pulses (12 J in 27 fs) at 3.3 Hz repetition rate. A fresh target surface for every shot was placed at the laser focus using an in-house tape target system designed to withstand large laser intensities and energies. It has been tested for different material thicknesses (25 and 7.6 µm), while L3-HAPLS delivered laser shots for energies ranging from 1 to 12 J. A technical description of the tape target system is given. The device can be used in diverse geometries needed for laser-matter interaction studies by providing an ≈300° free angle of view on the target in the equatorial plane. We show experimental data demonstrating the shot-to-shot stability of the device. An x-ray crystal spherical spectrometer was set up to measure the Kα yield stability, while a GHz H-field probe was used to check the shot-to-shot electromagnetic pulse generation. Finally, we discuss short and mid-term future improvements of the tape target system for efficient user operation.

The Relationship Between Behavioral Inhibition and Approach Motivation Systems (BIS/BAS) and Intrinsic Brain Network Connectivity in Adult Cannabis Users. Soc Cogn Affect Neurosci 2021; 16:985-994.

Abstract
Dampened behavioral inhibition and overactive behavioral approach motivation systems
(i.e. BIS/BAS) are associated with cannabis use disorder (CUD), although the underlying
neural mechanisms of these alterations have not yet been examined. The brain’s executive
control network (ECN) plays a role in decision-making and is associated with BIS/BAS. In
this study, we tested the hypothesis that altered ECN resting-state functional
connectivity (rsFC) underlies dysfunctional behavioral inhibition and approach motivation
in cannabis users. To that end, we collected resting-state functional magnetic resonance
imaging scans in 86 cannabis using adults and 59 non-using adults to examine group
differences in the relationship between ECN rsFC and BIS/BAS. Our results showed that BIS
was positively correlated with left ECN rsFC in cannabis users, while it was positively
correlated with right ECN rsFC in non-users. There was a trend-level moderation effect of
group on the association between BIS/BAS and ECN rsFC, showing a weaker association in
BIS/BAS and ECN rsFC in cannabis users compared to non-users. An exploratory mediation
analysis found that the severity of CUD mediated the relationship between users’ BIS
scores and left ECN rsFC. These findings suggest that cannabis use may lead to
dysregulation in typical ECN functional organization related to BIS/BAS.

Determinants of gender disparities in scaling up the first 90 towards the UNAIDS 90-90-90 targets in South Africa: findings from the 2017 household-based national cross-sectional survey. AIDS Res Ther 2021; 18:24.

Abstract
BACKGROUND The first 90 of UNAIDS 90-90-90 targets to have 90% of the people living with HIV know their status is an important entry point to the HIV treatment cascade and care continuum, but evidence shows that there is a large gap between males and females in this regard. It is therefore important to understand barriers and facilitators of achieving the first 90 target. This study examined determinants of the first 90 target among females and males in order to inform strategies aimed at improving the HIV cascade in South Africa. METHODS The data used in the analysis were obtained from a 2017 household-based cross-sectional nationally representative survey conducted using a multi-stage stratified cluster random sampling design. A series of hierarchical multiple logistic regression models were fitted to identify the determinants of the first 90 target by gender. RESULTS Overall, 84.8% of HIV-positive individuals aged 15 years and older were aware of their HIV status. Females were significantly more aware of their HIV status compared to males (88.7% vs 78.2%, p < 0.001). Both females aged 25 to 49 years [aOR = 3.20 (95% CI 1.35-7.57), p = 0.008], and 50 years and older [aOR = 3.19 (95% CI 1.04-9.76), p = 0.042] and males aged 25 to 49 years [aOR = 3.00 (95% CI 1.13-7.97), p = 0.028], and 50 years and older [aOR = 7.25 (95% CI 2.07-25.36), p = 0.002] were significantly more likely to know their HIV status compared to those aged 15 to 19 years. Males with tertiary education level were significantly more likely to be aware of their HIV positive status [aOR = 75.24 (95% CI 9.07-624.26), p < 0.001] compared to those with no education or with primary level education. Females with secondary [aOR = 3.28 (95% CI 1.20-8.99), p = 0.021] and matric [aOR = 4.35 (95% CI 1.54-12.37), p = 0.006] educational levels were significantly more likely to be aware of their HIV positive status, compared to those with no education or with primary level education. CONCLUSION Significant progress has been made with regards to reaching the UNAIDS first 90 target. In this context achieving the first 90 target is feasible but there is a need for additional interventions to reach the males especially youth including those with no education or low levels of education.

Abstract
Introduction Patients with severe mental illness experience physical health inequities. They are less likely to receive preventative care and adequate treatment for physical illnesses. Physical health screening of patients receiving antipsychotics is usually carried out every six months. This comprises screening bloodwork and ECGs, and the sharing of results with family physicians. Objectives We sought to investigate whether the pandemic affected the receipt of routine physical health screening in patients managed by an Assertive Community Treatment (ACT) Service. Methods A comprehensive chart review was performed on 62 ACT patients. We compared the receipt of screening bloodwork and ECGs from March—December 2020 to the same period in 2019. Results were analyzed using McNemar’s Chi square test with Yates’ correction. Results Patients were less likely to have received an ECG during the pandemic period. 69% received an ECG from March—December 2019 versus 42% from March—December 2020 (χ2= 7.76, p<0.01). Similarly, patients were less likely to have received screening bloodwork during the pandemic period (69% vs. 50%, Χ2= 4.32, p<0.05). Qualitative discussion with ACT staff regarding the 39 patients who had not received an ECG and/or bloodwork during the pandemic period revealed system-related (8%), patient-related (23%), and Covid-related (69%) barriers to screening. Covid-related barriers included transport concerns and lab closures. Conclusions ACT patients were less likely to have received routine health screening during the Covid-19 pandemic. Thus, the pandemic may have exacerbated physical health inequities for patients with severe mental illness. Covid-related barriers to screening represent an important target for intervention. Disclosure No significant relationships.

Abstract
The rare decay K_{L}→π^{0}νν[over ¯] was studied with the dataset taken at the J-PARC KOTO experiment in 2016, 2017, and 2018. With a single event sensitivity of (7.20±0.05_{stat}±0.66_{syst})×10^{-10}, three candidate events were observed in the signal region. After unveiling them, contaminations from K^{±} and scattered K_{L} decays were studied, and the total number of background events was estimated to be 1.22±0.26. We conclude that the number of observed events is statistically consistent with the background expectation. For this dataset, we set an upper limit of 4.9×10^{-9} on the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level.

Abstract
Abstract
Background
Dilated Cardiomyopathy (DCM) represents a specific subgroup of non-ischemic cardiomyopathies. Little is known about the genotypic characterization of dilated cardiomyopathy (DCM) patients diagnosed over 60 years of age.
Aim
To investigate prevalence, characterization and prognostic impact of the genetic background of late-onset DCM patients.
Methods
We analyzed a study population of 566 DCM patients from two international referral centers. Genetic background was analyzed and patients were grouped into typical-onset DCM (<60 years of age at diagnosis) or late-onset DCM (>60 years of age at diagnosis).
Results
Approximately 12% of patients (n=70) had late-onset DCM and female sex was significantly more frequent in the late-onset DCM cohort (p<0.001). Diagnostic yield of genetic testing was comparable between typical- and late-onset DCM (53% vs 50%, respectively p=0.438) whereas the prevalence of Titin gene truncation variants (TTNtv) was higher in the late-onset DCM group compared to the younger cohort (23% vs 13% respectively; p<0.05). Notably, patients with late-onset genetic DCM had comparable long-term outcomes to those with typical-onset DCM.
Conclusions
Late-onset DCM patients have nearly double the rate of TTNtv mutations and are more likely to be female compared to younger DCM patients. These observed differences in mutational makeup and sex may reveal insights into age and sex dependent mechanisms for TTNtv and should prompt further study. Notably, the increased prevalence of TTNtv and female sex did not translate into noticeable differences in rates of measurable cardiac events.

Abstract
Abstract
Background
Danon Disease (DD) is a rare X-linked autophagic disorder due to mutations in the Lysosomal Associated Membrane Protein 2 (LAMP-2) gene and causes severe cardiac manifestations. Measurement of longitudinal strain (LS) has been shown to provide diagnostic insights into different etiologies of hypertrophic cardiomyopathies compared to conventional echocardiographic parameters.
Purpose
The aim of this study was to describe the pattern of global and regional LS in DD.
Methods
A retrospective, international registry, using medical records provided by patients, was formed to describe the natural history of DD. Complete echocardiogram images were available for review and LS was analyzed globally and regionally (basal, mid, apex).
Results
A total of eighteen DD patients (male 72%, mean age 17.2±10 years) had sufficient quality echocardiographic images for both traditional and myocardial strain evaluation. Notable traditional echocardiographic parameters included a mean EF of 60±11%, LV mass index 200±159 g/m2, intraventricular septal diameter 17.7±10.3 mm, LV posterior wall diameter 16.1±7.7 mm, LA volume index 21.9±13 mL/m2. Global longitudinal strain was reduced with a mean of −12.1±4.9% with an observed regional strain gradient: apex (−16.6±6.6%), mid (−10.9±4.7%) and basal (−9.2±4.5%). Bull's eye plot patterns reflected an apical sparing pattern that was similar to that described in cardiac amyloidosis.
Conclusion
In this DD cohort, we describe for the first time a strain pattern characterized by reduction in global longitudinal strain with apical sparing, which was originally pathognomonic for cardiac amyloidosis. This strain pattern in conjunction with a paradoxically normal LA volume may discriminate patients with DD from other hypertrophic conditions.
