Abstract Plasmodium falciparum malaria contributes to a significant global disease burden. Circumsporozoite protein (CSP), the most abundant sporozoite stage antigen, is a prime vaccine candidate. Inhibitory monoclonal antibodies (mAbs) against CSP map to either a short junctional sequence or the central (NPNA)n repeat region. We compared in vitro and in vivo activities of six CSP-specific mAbs derived from human recipients of a recombinant CSP vaccine RTS,S/AS01 (mAbs 317 and 311); an irradiated whole sporozoite vaccine PfSPZ (mAbs CIS43 and MGG4); or individuals exposed to malaria (mAbs 580 and 663). RTS,S mAb 317 that specifically binds the (NPNA)n epitope, had the highest affinity and it elicited the best sterile protection in mice. The most potent inhibitor of sporozoite invasion in vitro was mAb CIS43 which shows dual-specific binding to the junctional sequence and (NPNA)n. In vivo mouse protection was associated with the mAb reactivity to the NANPx6 peptide, the in vitro inhibition of sporozoite invasion activity, and kinetic parameters measured using intact mAbs or their Fab fragments. Buried surface area between mAb and its target epitope was also associated with in vivo protection. Association and disconnects between in vitro and in vivo readouts has important implications for the design and down-selection of the next generation of CSP based interventions.

Abstract Background Powered exoskeletons provide a way to stand and walk for people with severe spinal cord injury. Here, we used the ReWalk exoskeleton to determine the training dosage required for walking proficiency, the sensory and motor changes in the nervous system with training, and the functionality of the device in a home-like environment. Methods Participants with chronic (> 1 yr) motor complete or incomplete spinal cord injury, who were primarily wheelchair users, were trained to walk in the ReWalk for 12 weeks. Measures were taken before, during, immediately after, and 2–3 months after training. Measures included walking progression, sitting balance, skin sensation, spasticity, and strength of the corticospinal tracts. Results Twelve participants were enrolled with 10 completing training. Training progression and walking ability: The progression in training indicated about 45 sessions to reach 80% of final performance in training. By the end of training, participants walked at speeds of 0.28–0.60 m/s, and distances of 0.74–1.97 km in 1 h. The effort of walking was about 3.3 times that for manual wheelchair propulsion. One non-walker with an incomplete injury became a walker without the ReWalk after training. Sensory and motor measures: Sitting balance was improved in some, as seen from the limits of stability and sway speed. Neuropathic pain showed no long term changes. Change in spasticity was mixed with suggestion of differences between those with high versus low spasticity prior to training. The strength of motor pathways from the brain to back extensor muscles remained unchanged. Adverse events: Minor adverse events were encountered by the participants and trainer (skin abrasions, non-injurious falls). Field testing: The majority of participants could walk on uneven surfaces outdoors. Some limitations were encountered in home-like environments. Conclusion For individuals with severe SCI, walking proficiency in the ReWalk requires about 45 sessions of training. The training was accompanied by functional improvements in some, especially in people with incomplete injuries. Trial registration NCT02322125 Registered 22 December 2014.

Abstract Background Despite growing evidence of a critical link between neuromodulation technologies and neuroplastic recovery, the underlying mechanisms of these technologies remain elusive. Objective To investigate physiological evidence of central nervous system (CNS) changes in humans during translingual neurostimulation (TLNS). Methods We used high-density electroencephalography (EEG) to measure changes in resting brain activity before, during, and after high frequency (HF) and low frequency (LF) TLNS. Results Wavelet power analysis around Cz and microstate analysis revealed significant changes after 20 min of stimulation compared to baseline. A secondary effect of exposure order was also identified, indicating a differential neuromodulatory influence of HF TLNS relative to LF TLNS on alpha and theta signal power. Conclusions These results further our understanding of the effects of TLNS on underlying resting brain activity, which in the long-term may contribute to the critical link between clinical effect and changes in brain activity.

Using a longitudinal case study design, we have tracked the recovery of motor function following severe traumatic brain injury (TBI) through a multimodal neuroimaging approach. In 2006, Canadian Soldier Captain (retired) Trevor Greene (TG) was attacked with an axe to the head while on tour in Afghanistan. TG continues intensive daily rehabilitation, which recently included the integration of physical therapy (PT) with neuromodulation using translingual neurostimulation (TLNS) to facilitate neuroplasticity. Recent findings with PT + TLNS demonstrated that recovery of motor function occurred beyond conventional time limits, currently extending past 14-years post-injury. To investigate whether PT + TLNS similarly resulted in associated cognitive function improvements, we examined event-related potentials (ERPs) with the brain vital signs framework. In parallel with motor function improvements, brain vital signs detected significant increases in basic attention (as measured by P300 response amplitude) and cognitive processing (as measured by contextual N400 response amplitude). These objective cognitive improvements corresponded with TG’s self-reported improvements, including a noteworthy and consistent reduction in ongoing symptoms of post-traumatic stress disorder (PTSD). The findings provide valuable insight into the potential importance of non-invasive neuromodulation in cognitive rehabilitation, in addition to initial indications for physical rehabilitation.

BACKGROUND: The prevalence of atrial fibrillation(AF) and diabetes mellitus is rising to epidemic proportions. We aimed to assess the impact of diabetes on the management and outcomes of patients with AF.METHODS: The EORP-AF General Long-Term Registry is a prospective, observational registry from 250 centres across 27 European countries. Outcomes of interest were as follows: i)rhythm control interventions; ii)quality of life; iii)healthcare resource utilisation; and iv)major adverse events.RESULTS: Of 11,028 patients with AF, the median age was 71 (63-77) years and 2537 (23.0%) had diabetes. Median follow-up was 24 months. Diabetes was related to increased use of anticoagulation but less rhythm control interventions. Using multivariable analysis, at 2-year follow-up, patients with diabetes were associated with greater levels of anxiety (p = 0.038) compared to those without diabetes. Overall, diabetes was associated with worse health during follow-up, as indicated by Health Utility Score and Visual Analogue Scale. Healthcare resource utilisation was greater with diabetes in terms of length of hospital stay (8.1 (±8.2) vs. 6.1 (±6.7) days); cardiology and internal medicine/general practitioner visits; and emergency room admissions. Diabetes was an independent risk factor of major adverse cardiovascular event (MACE; HR 1.26 [95% CI, 1.04-1.52]), all-cause mortality (HR 1.28 [95% CI, 1.08-1.52]), and cardiovascular mortality (HR 1.41 [95% CI, 1.09-1.83]).CONCLUSION: In this contemporary AF cohort, diabetes was present in 1 in 4 patients and it served as an independent risk factor for reduced quality of life, greater healthcare resource utilisation and excess MACE, all-cause mortality and cardiovascular mortality. There was increased use of anticoagulation therapy in diabetes but with less rhythm control interventions.

Plasmodium falciparum malaria contributes to a significant global disease burden. Circumsporozoite protein (CSP), the most abundant sporozoite stage antigen, is a prime vaccine candidate. Inhibitory monoclonal antibodies (mAbs) against CSP map to either a short junctional sequence or the central (NPNA)n repeat region. We compared in vitro and in vivo activities of six CSP-specific mAbs derived from human recipients of a recombinant CSP vaccine RTS,S/AS01 (mAbs 317 and 311); an irradiated whole sporozoite vaccine PfSPZ (mAbs CIS43 and MGG4); or individuals exposed to malaria (mAbs 580 and 663). RTS,S mAb 317 that specifically binds the (NPNA)n epitope, had the highest affinity and it elicited the best sterile protection in mice. The most potent inhibitor of sporozoite invasion in vitro was mAb CIS43 which shows dual-specific binding to the junctional sequence and (NPNA)n. In vivo mouse protection was associated with the mAb reactivity to the NANPx6 peptide, the in vitro inhibition of sporozoite invasion activity, and kinetic parameters measured using intact mAbs or their Fab fragments. Buried surface area between mAb and its target epitope was also associated with in vivo protection. Association and disconnects between in vitro and in vivo readouts has important implications for the design and down-selection of the next generation of CSP based interventions.

Background In a recent high-profile case study, we used functional magnetic resonance imaging (fMRI) to monitor improvements in motor function related to neuroplasticity following rehabilitation for severe traumatic brain injury (TBI). The findings demonstrated that motor function improvements can occur years beyond current established limits. The current study extends the functional imaging investigation to characterize neuromodulation effects on neuroplasticity to further push the limits. Methods Canadian Soldier Captain (retired) Trevor Greene (TG) survived a severe open-TBI when attacked with an axe during a 2006 combat tour in Afghanistan. TG has since continued intensive daily rehabilitation to recover motor function, experiencing an extended plateau using conventional physical therapy. To overcome this plateau, we paired translingual neurostimulation (TLNS) with the continuing rehabilitation program. Results Combining TLNS with rehabilitation resulted in demonstrable clinical improvements along with corresponding changes in movement evoked electro-encephalography (EEG) activity. High-density magneto-encephalography (MEG) characterized cortical activation changes in corresponding beta frequency range (27 Hz). MEG activation changes corresponded with reduced interhemispheric inhibition in the post-central gyri regions together with increased right superior/middle frontal activation suggesting large scale network level changes. Conclusions The findings provide valuable insight into the potential importance of non-invasive neuromodulation to enhance neuroplasticity mechanisms for recovery beyond the perceived limits of rehabilitation.

BACKGROUND: Cardiac troponins (cTn) have been reported to be predictors for adverse outcomes in atrial fibrillation (AF), patients, but their actual use is still unclear.AIM: To assess the factors associated with cTn testing in routine practice and evaluate the association with outcomes.METHODS: Patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry were stratified into 3 groups according to cTn levels as (i) cTn not tested, (ii) cTn in range (≤99th percentile), (iii) cTn elevated (>99th percentile). The composite outcome of any thromboembolism /any acute coronary syndrome/cardiovascular (CV) death, defined as Major Adverse Cardiovascular Events (MACE) and all-cause death were the main endpoints.RESULTS: Among 10 445 AF patients (median age 71 years, 40.3% females) cTn were tested in 2834 (27.1%). cTn was elevated in 904/2834 (31.9%) and in-range in 1930/2834 (68.1%) patients. Female sex, in-hospital enrollment, first-detected AF, CV risk factors, history of coronary artery disease, and atypical AF symptoms were independently associated with cTn testing. Elevated cTn were independently associated with a higher risk for MACE (Model 1, hazard ratio [HR] 1.74, 95% confidence interval [CI] 1.40-2.16, Model 2, HR 1.62, 95% CI 1.28-2.05; Model 3 HR 1.76, 95% CI 1.37-2.26) and all-cause death (Model 1, HR 1.45, 95% CI 1.21-1.74; Model 2, HR 1.36, 95% CI 1.12-1.66; Model 3, HR 1.38, 95% CI 1.12-1.71).CONCLUSIONS: Elevated cTn levels were associated with an increased risk of all-cause mortality and adverse CV events. Clinical factors that might enhance the need to rule out CAD were associated with cTn testing.

The control processes that guide attention to a visual-search target can result in the selection of an irrelevant object with similar features (a distractor). Once attention is captured by such a distractor, search for a subsequent target is momentarily impaired if the two stimuli appear at different locations. The textbook explanation for this impairment is based on the notion of an indivisible focus of attention that moves to the distractor, illuminates a nontarget that subsequently appears at that location, and then moves to the target once the nontarget is rejected. Here, we show that such delayed orienting to the target does not underlie the behavioral cost of distraction. Observers identified a color-defined target appearing within the second of two stimulus arrays. The first array contained irrelevant items, including one that shared the target's color. ERPs were examined to test two predictions stemming from the textbook serial-orienting hypothesis. Namely, when the target and distractor appear at different locations, (1) the target should elicit delayed selection activity relative to same-location trials, and (2) the nontarget search item appearing at the distractor location should elicit selection activity that precedes selection activity tied to the target. Here, the posterior contralateral N2 component was used to track selection of each of these search-array items and the previous distractor. The results supported neither prediction above, thereby disconfirming the serial-orienting hypothesis. Overall, the results show that the behavioral costs of distraction are caused by perceptual and postperceptual competition between concurrently attended target and nontarget stimuli.

Significance RTS,S/AS01 is a circumsporozoite protein (CSP)-based malaria vaccine that confers partial protection against malaria in endemic areas. Recent reports have elucidated structures of monoclonal antibodies that bind to the central (NPNA) repeat region of CSP and that inhibit parasite invasion. Antigen configuration and copy number of CSP repeats displayed on a tobacco mosaic virus (TMV) particle platform were studied. A TMV vaccine containing CSP repeats displayed as a loop induced 10× better antibody titer than a nearly full-length CSP in mice. In rhesus model, this translated to a 5× improvement in titer. Rhesus antibodies potently inhibited parasite invasion up to 11 mo after vaccination. An optimized epitope-focused, repeat-only CSP vaccine may be sufficient or better than the existing CSP vaccines., Plasmodium falciparum vaccine RTS,S/AS01 is based on the major NPNA repeat and the C-terminal region of the circumsporozoite protein (CSP). RTS,S-induced NPNA-specific antibody titer and avidity have been associated with high-level protection in naïve subjects, but efficacy and longevity in target populations is relatively low. In an effort to improve upon RTS,S, a minimal repeat-only, epitope-focused, protective, malaria vaccine was designed. Repeat antigen copy number and flexibility was optimized using the tobacco mosaic virus (TMV) display platform. Comparing antigenicity of TMV displaying 3 to 20 copies of NPNA revealed that low copy number can reduce the abundance of low-affinity monoclonal antibody (mAb) epitopes while retaining high-affinity mAb epitopes. TMV presentation improved titer and avidity of repeat-specific Abs compared to a nearly full-length protein vaccine (FL-CSP). NPNAx5 antigen displayed as a loop on the TMV particle was found to be most optimal and its efficacy could be further augmented by combination with a human-use adjuvant ALFQ that contains immune-stimulators. These data were confirmed in rhesus macaques where a low dose of TMV-NPNAx5 elicited Abs that persisted at functional levels for up to 11 mo. We show here a complex association between NPNA copy number, flexibility, antigenicity, immunogenicity, and efficacy of CSP-based vaccines. We hypothesize that designing minimal epitope CSP vaccines could confer better and more durable protection against malaria. Preclinical data presented here supports the evaluation of TMV-NPNAx5/ALFQ in human trials.

Exploration of animal models leads to discoveries that can reveal candidate biomarkers for translation to human populations. Herein, a model of hepatocarcinogenesis and protection was used in which rats treated with aflatoxin (AFB1 ) daily for 28 days (200 µg/kg BW) developed tumors compared with rats completely protected from tumors by concurrent administration of the chemoprotective agent, 1-[2-cyano-3-,12-dioxooleana-1,9(11)-dien-28-oyl]imidazole (CDDO-Im). Differential expression of miRNAs in tumors (AFB1 ) and nontumor (AFB1 + CDDO-Im) bearing livers and their levels in sera over the life-course of the animals was determined. miRNA transcriptome analysis identified 17 miRNAs significantly upregulated at greater than five-fold in the tumors. The ten most dysregulated miRNAs judged by fold-change and biological significance were selected for further study, including liver-specific miR-122-5p. Validation of sequencing results by real-time PCR confirmed the upregulation of the majority of these miRNAs in tumors, including miR-182, as well as miR-224-5p as the most dysregulated of these miRNAs (over 400-fold). The longitudinal analysis of levels of miR-182 in sera demonstrated significant and persistent increases (5.13-fold; 95% CI: 4.59-5.70). The increase in miR-182 was detected months before any clinical symptoms were present in the animals. By the terminal time point of the study, in addition to elevated levels of serum miR-182, serum miR-122-5p was also found to be increased (>1.5-fold) in animals that developed hepatocarcinomas. Thus, using the data from an unbiased discovery approach of the tissue findings, serum miR-182 was found to track across the complex, multistage process of hepatocarcinogenesis opening an opportunity for translation to human populations.

Social-distancing directives to contain community transmission of the COVID-19 virus can be expected to affect sleep timing, duration or quality. Remote work or school may increase time available for sleep, with benefits for immune function and mental health, particularly in those individuals who obtain less sleep than age-adjusted recommendations. Young adults are thought to regularly carry significant sleep debt related in part to misalignment between endogenous circadian clock time and social time. We examined the impact of social-distancing measures on sleep in young adults by comparing sleep self-studies submitted by students enrolled in a university course during the 2020 summer session (entirely remote instruction, N = 80) with self-studies submitted by students enrolled in the same course during previous summer semesters (on-campus instruction, N = 452; cross-sectional study design). Self-studies included 2–8 week sleep diaries, two chronotype questionnaires, written reports, and sleep tracker (Fitbit) data from a subsample. Students in the 2020 remote instruction semester slept later, less efficiently, less at night and more in the day, but did not sleep more overall despite online, asynchronous classes and ~44% fewer work days compared to students in previous summers. Subjectively, the net impact on sleep was judged as positive or negative in equal numbers of students, with students identifying as evening types significantly more likely to report a positive impact, and morning types a negative impact. Several features of the data suggest that the average amount of sleep reported by students in this summer course, historically and during the 2020 remote school semester, represents a homeostatic balance, rather than a chronic deficit. Regardless of the interpretation, the results provide additional evidence that social-distancing measures affect sleep in heterogeneous ways.

Aflatoxin B1 (AFB1) is a potent human and animal hepatocarcinogen. To investigate the effects of aflatoxin on miRNA expression during the initiation phase of carcinogenesis, next-generation sequencing was used to analyze liver tissues from F344 rats exposed to 200 µg/kg per day AFB1 for 4 weeks. A panel of miRNAs was identified that was upregulated with AFB1 treatment compared to controls: rno-miR-434-3p, rno-miR-411-5p, rno-miR-221-3p, rno-miR-127-3p, rno-miR-205, rno-miR-429, rno-miR-34a-5p, rno-miR-181c-3p, rno-miR-200b-3p, and rno-miR-541-5p. Analysis of rat livers exposed to AFB1 plus the chemopreventive triterpenoid CDDO-Im revealed a striking abrogation of this upregulation. These changes were validated by real-time PCR. We also explored the temporal variation in expression of the candidate miRNAs during the 4-week dosing period. Most of the candidate miRNAs were upregulated at week 1 and increased for the duration of AFB1 dosing over the 4-week period. Treatment with CDDO-Im ameliorated these effects at all time points. All candidate miRNAs were detectable in serum from aflatoxin treated animals; however, there was no significant difference in expression for 7 of the 11 miRNAs examined. Exposure to AFB1 upregulated miR-122-5p (5 fold), 34a-5p (13 fold), and 181c-3p (170 fold) compared with controls. The findings from this study give insight into epigenetic changes induced by aflatoxin taking place during the initial step of carcinogenesis. This article is protected by copyright.

Background Despite growing evidence of a critical link between neuromodulation technologies and neuroplastic recovery, the underlying mechanisms of these technologies remain elusive. Objective To investigate physiological evidence of central nervous system (CNS) changes in humans during translingual neurostimulation (TLNS). Methods We used high-density electroencephalography (EEG) to measure changes in resting brain activity before, during, and after high frequency (HF) and low frequency (LF) TLNS. Results Wavelet power analysis around Cz and microstate analysis revealed significant changes after 20 min of stimulation compared to baseline. A secondary effect of exposure order was also identified, indicating a differential neuromodulatory influence of HF TLNS relative to LF TLNS on alpha and theta signal power. Conclusions These results further our understanding of the effects of TLNS on underlying resting brain activity, which in the long-term may contribute to the critical link between clinical effect and changes in brain activity.

Evening-type individuals often perform poorly in the morning because of a mismatch between internal circadian time and external social time, a condition recognized as social jet lag. Performance impairments near the morning circadian (~24 hr) trough have been attributed to deficits in attention, but the nature of the impairment is unknown. Using electrophysiological indices of attentional selection (N2pc) and suppression (PD ), we show that evening-type individuals have a specific disability in suppressing irrelevant visual distractions. More specifically, evening-type individuals managed to suppress a salient distractor in an afternoon testing session, as evidenced by a PD , but were less able to suppress the distractor in a morning testing session, as evidenced by an attenuated PD and a concomitant distractor-elicited N2pc. Morning chronotypes, who would be well past their circadian trough at the time of testing, did not show this deficit at either test time. These results indicate that failure to filter out irrelevant stimuli at an early stage of perceptual processing contributes to impaired cognitive functioning at nonoptimal times of day and may underlie real-world performance impairments, such as distracted driving, that have been associated with circadian mismatch.

- Abstract
Marine bioregional planning requires a meaningful classification and spatial delineation of the ocean environment using biological and physical characteristics. The relative inaccessibility of much of the ocean and the paucity of directly measured data spanning entire planning regions mean that surrogate data, such as satellite imagery, are frequently used to develop spatial classifications. However, due to a lack of appropriate biological data, these classifications often rely on abiotic variables, which act as surrogates for biodiversity. The aim of this study was to produce a fine-scale bioregional classification, using multivariate clustering, for the inshore and offshore marine environment off the east coast of South Africa, adjacent to the province of KwaZulu-Natal and out to the boundary of the exclusive economic zone (EEZ), 200 nautical miles offshore. We used remotely sensed data of sea surface temperature, chlorophyll a and turbidity, together with interpolated bathymetry and continental-slope data, as well as additional inshore data on sediments, seabed oxygen and bottom temperature. A multivariate k-means analysis was used to produce a fine-scale marine bioregionalisation, with three bioregions subdivided into 12 biozones. The offshore classification was primarily a pelagic bioregionalisation, whereas the inshore classification (on the continental shelf) was a coupled benthopelagic bioregionalisation, owing to the availability of benthic data for this area. The resulting classification was used as a base layer for a systematic conservation plan developed for the province, and provided the methods for subsequent planning conducted for the entire South African EEZ. Validation of the classification is currently being conducted in marine research programmes that are sampling benthic biota and habitats in a sampling design stratified according to the biozones delineated in this study.

Irrelevant visual cues capture attention when they possess a task-relevant feature. Electrophysiologically, this contingent capture of attention is evidenced by the N2pc component of the visual event-related potential (ERP) and an enlarged ERP positivity over the occipital hemisphere contralateral to the cued location. The N2pc reflects an early stage of attentional selection, but presently it is unclear what the contralateral ERP positivity reflects. One hypothesis is that it reflects the perceptual enhancement of the cued search-array item; another hypothesis is that it is time-locked to the preceding cue display and reflects active suppression of the cue itself. Here, we varied the time interval between a cue display and a subsequent target display to evaluate these competing hypotheses. The results demonstrated that the contralateral ERP positivity is tightly time-locked to the appearance of the search display rather than the cue display, thereby supporting the perceptual enhancement hypothesis and disconfirming the cue-suppression hypothesis.

Hepatocellular carcinoma (HCC) continues to be a major cause of cancer death globally, with aflatoxin B1 (AFB1) as a prevalent risk factor in low- and middle-income countries. MicroRNAs have been shown to be differentially expressed in HCC and may serve as predictive biomarkers. In this study, we analyzed tumor and non-tumor tissue from rats dosed with AFB1 (200 µg/kg BW) for 28 consecutive days that received vehicle only or AFB1 plus the chemopreventive agent CDDO-Im (30 µmol), and control animals (Johnson et al., CaPR, 2014). Total RNA was isolated from tumor or non-tumor tissue at the time of sacrifice and sequenced. MicroRNA transcriptomic analysis revealed 17 miRNAs significantly upregulated (> 5 fold) in tumors compared to non-tumor tissue. The top ten dysregulated miRNAs determined by fold change and biological significance were selected for further investigation: rno-miR- 205, 200b-3p, 182, 429, 31a-5p, 10b-5p, 141-3p, 132-3p, 802-5p. Validation of sequencing results by quantitative PCR (qPCR) confirmed the upregulation of the majority of candidate miRNAs in tumors and rno-miR-224-5p as the most dysregulated miRNA (over 400 fold). We also examined the levels of these candidates in terminal sera of the same animals by qPCR. Circulating miRs-224-5p, 182, and 122-5p were increased (> 1.5 fold) in animals diagnosed with HCC compared to untreated animals and those previously dosed with AFB1 plus CDDO-Im. Analysis of tracking of serum miR-182 by generalized estimating equations (GEE) revealed significantly increased levels (5 fold; CI: 2.17- 2.50) in animals that developed HCC. This sustained increase in serum miR-182 is seen months before any tumors or other symptoms are present, and highlights this miRNA as a potential predictive biomarker in AFB1-induced HCC.

Liver cancer is the second leading cause of cancer death worldwide: risk factors include the viruses, HBV and HCV, and the environmental carcinogen aflatoxin B1 (AFB1). Chemoprevention strategies that activate genes controlled by the KEAP1-NRF2 pathway, such as CDDO-Im, afford complete protection against AFB1-induced hepatocarcinogenesis in rats. The opportunity to deploy these types of agents in high-risk populations would be advanced by the validation of biomarkers reflecting their efficacy. MicroRNAs (miRNAs) affecting gene expression are important in normal physiology and have been shown to be frequently dysregulated in cancer. It is our hypothesis that specific rat liver miRNAs are biomarkers that temporally track with AFB1-induced liver cancer, and are modulated in animals that receive complete protection by CDDO-Im. MiRNAs were isolated from archived liver tissue of rats (Johnson et al., CaPR, 2014) that were dosed with AFB1 (200 μg) for 28 consecutive days. Two additional groups received either vehicle only or AFB1 + CDDO-Im (30 μmol). After RNA isolation (miRCURY tissue, Exiqon), samples were profiled by RNA sequencing (Illumina). Fourteen miRNAs were selected based on dynamic range and level of detection for validation by RT-qPCR (TaqMan microRNA assay). MiRNA profiling from animals at the end of the carcinogenic 28-day dosing regimen revealed an increased total number of miRNAs due to AFB1 exposure alone (n≈500) compared to control. Those miRNAs displaying a greater than 10 fold increase in expression between control and AFB1 treatment groups were examined in detail: 541-5p, 34a-5p, 127-3p, 205, 434-3p, 429, 411-5p, 181c-3p, 200b-3p, 221-3p. RNA-seq data showed that these were all upregulated in the AFB1-treated samples. Co-treatment with CDDO-Im shifted expression levels back to control. The miRNAs 192-3p, 92a-3p, 26b-3p, and 375-3p were expressed consistently in all treatment groups and were selected for normalization. Expression levels of the 14 candidate miRNAs were then examined in liver samples obtained from rats after 7, 14 and 21 doses AFB1 and compared to levels determined at week 4 (28 doses AFB1). Quantitative analysis demonstrated an increase in expression of the panel of miRNAs due to AFB1 exposure over the dosing period, potentially indicating a role in early carcinogenesis. MicroRNA expression showed a varying trend over time in animals treated with AFB1 plus CDDO-Im. Three invariant miRNAs (miR-375-3p, 92a-3p, 192-3p) showed little change during the 28-day exposure period. In conclusion, we have identified a panel of miRNAs that are upregulated and track with AFB1 exposure. These changes are abrogated by treatment with CDDO-Im and thus reflect the protective efficacy of the intervention. Supported by T32ES007141-31A1 and CA197222. Citation Format: Merricka C.

Parekh S, Xu L, and Livingstone C
- Abstract
Background: Anticoagulants are life-saving medicines that can prevent strokes for patients diagnosed with atrial fibrillation (AF) as well as treating patients with venous thromboembolism (VTE), but when used incorrectly, they are frequently associated with patient harm., Aim: To evaluate the impact of community pharmacy teams on optimising patient knowledge and awareness and improving medication safety from the use of anticoagulants., Methods: Two national audits, consisting of 17 questions assessing and improving patients' understanding of anticoagulant therapy, identifying high-risk patients, and contacting prescribers when clinically appropriate were incentivised for England's community pharmacies in 2021-2022 and 2023-2024 using the Pharmacy Quality Scheme (PQS) commissioned by NHS England., Results: Approximately 11,000 community pharmacies audited just under a quarter of a million patients in total, whilst making almost 150,000 interventions for patients taking oral anticoagulants, i.e., identifying and addressing medication issues which could increase the risk of bleeding/harm. Out of the 111,195 patients audited in 2021-2022, only 24,545 (23%) patients were prescribed vitamin K antagonists. The remaining patients were prescribed direct oral anticoagulants (DOACs). By 2023-2024, this decreased to 17,043 (16%) patients. Most patients knew that they were prescribed an anticoagulant (95.6%, 106,255 in 2021-2022 and 96.5%, 101,006 in 2023-2024, p < 0.001)., Discussion: The audits resulted in a statistically significant increase in patients with a standard yellow anticoagulant alert card, as identified in audit 2 (73,901 66.5% in 2021-2022 to 76,735, 73.3% in 2023-2024, p < 0.001). Furthermore, fewer patients were prescribed concurrent antiplatelets with an anticoagulant (6021; 4.6% in 2021-2022 to 4975; 4% in 2023-2024, p < 0.001). Although there was an increase in the number of patients prescribed NSAIDs with anticoagulants, more of these patients were also prescribed gastroprotection concurrently (927 77.2% in 2021-2022 to 1457 84.1% in 2023-2024, p < 0.05). The majority of patients on warfarin had their blood checked within 12 weeks. Further there was an increase for these patients in the percentage of people prescribed VKAs who knew dietary changes can affect their anticoagulant medicine (16,764 67.4% in 2021-2022 to 12,594 73.9% in 2023-2024 p < 0.001)., Conclusions: Community pharmacy teams are well placed in educating and counselling patients on the safe use of anticoagulants and ensuring that all patients are correctly monitored.

- Abstract
Stigma reduces access to alcohol and other drug (AOD) support. This systematic review explored perceptions and experiences of stigma associated with AOD use among migrant and ethnic minority groups. Qualitative studies published in English were identified using six databases. Two reviewers screened and critically appraised articles using the Joanna Briggs Institute Critical Appraisal Checklist for qualitative studies. Data were synthesised using best fit framework synthesis. Twenty-three studies were included. Stigma drivers and facilitators included stereotypes, socio-cultural norms, legal responses and precarious lived experiences. Stigma intersected with gender, citizenship, race and ethnicity and manifested though shame, exclusion, secondary stigma and discrimination in treatment. Outcomes and impacts included avoidance of services, emotional distress, isolation and loneliness. This review identified similar stigma experiences to other populations, however outcomes were complicated by precarious lived experiences and multiple stigmatised identities. Multi-level interventions are required to reduce AOD-related stigma for migrant and ethnic minority groups., (© 2023. The Author(s).)

- Abstract
The National Health Protection (NHP) of Indonesia is a pro-poor social health insurance as the government pays the monthly premium for the poor. A waste picker is classified as an urban poor group needing affordable or free access to health care. This study explores the extent to which the NHP protects the health of waste pickers and provides them with quality health care. For this mixed-method study, 342 waste pickers completed the survey, 40 engaged in interviews, and 15 participated in Natural Group Discussions. The study found that 20% of waste pickers were not enrolled in NHP due to issues such as incorrect validation of poverty, discrimination, illegal fees, nepotism, unaffordable premiums, and lack of interest in purchasing the health plan. Among those who were enrolled, waste pickers expressed satisfaction with the health care they received and the behavior of the staff. However, they did criticize certain aspects such as waiting times, service gaps between full-paying and subsidized patients, suspicion of the quality of medicines, complicated medical administration procedures, and inflexibility of the capitation system. The study concludes that despite the NHP, poor groups remain vulnerable to accessing free health care., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Internationally, the prevalence of gambling disorder has been reported to be higher among homeless people than the general population; however, little is known about the factors associated with gambling disorder in this population. The present study aimed to investigate the prevalence of gambling disorder and its associated factors among homeless men using shelters in Osaka City. A cross-sectional survey was conducted from 30 to 2018 to 4 January 2019, using the 2017 Japanese National Survey of Gambling (JNSG) questionnaire, supplemented with questions about homeless experiences, drinking, and smoking. Using the South Oaks Gambling Screen, the presence of gambling disorder was determined by a score ≥ 5 out of 20. Multivariate logistic regression was conducted to explore factors associated with lifetime gambling disorder. Lifetime and past-year prevalence of gambling disorder among 103 participants was 43.7% (95% confidence interval [CI]: 34.5-53.3) and 3.9% (95% CI: 1.5-9.6), respectively, which are higher than the 6.7% and 1.5% found among men in the 2017 JNSG. Reasons reported for currently gambling less were primarily financial. Factors associated with lifetime GD included "more than 20 years since the first incidence of homelessness" (adjusted odds ratio [AOR]: 4.97, 95% CI: 1.50-16.45) and "more than five incidences of homelessness" (AOR: 4.51, 95% CI: 1.06-19.26). When homeless individuals with gambling disorder try to rebuild and stabilize their lives, the presence or resurgence of gambling disorder may hinder the process and pose a risk of recurring homelessness. Comprehensive support services for homeless individuals with gambling disorder are required. (250 words)., (© 2022. The Author(s).)

- Abstract
Introduction: Excessive alcohol use is associated with non-communicable diseases and social problems, such as work absence, financial problems and family violence. Expenditure and expenditure shares on alcohol are valuable measures to monitor financial activities on this risk behaviour. The aim of this paper is to report trends in alcohol expenditure in Australia over the last two decades., Methods: Data are from six waves of Australian Household Expenditure Surveys from 1984 to 2015-2016. We explored trends of alcohol expenditure among Australians and in different socio-demographic groups in the last 30 years. We further examined changes of expenditure on different on- and off-premises beverages over time., Results: Absolute alcohol expenditure has remained the same between the 1980s and 2016, after accounting for inflation. However, a declining trend in relative alcohol expenditure as a proportion of total household expenditure was found across nearly all demographic groups (e.g., sex, age, employment, household income), except for women aged 45-54, who showed an increasing trend of alcohol expenditure after 1998-1999., Discussion and Conclusions: The current study shows declines in relative alcohol expenditure, which may reflect declines in alcohol's relative importance within the elements of the person's lifestyle they need to pay for and/or increased awareness of alcohol's health and social harms. Further longitudinal analysis should explore additional predictors of household expenditure on alcohol. Results suggest that current bi-annual indexation increases in alcohol tax should account for increases in income to ensure the effectiveness of pricing. Moreover, attention is needed to address drinking among middle-aged females., (© 2023 The Authors.

- Abstract
Introduction: Losses disguised as wins (LDWs) are a salient type of losing outcome common to electronic gambling machines (EGMs). These events occur when a gambling payout is less than the amount wagered (i.e., a net loss) but is nonetheless accompanied by the sounds and animations that accompany genuine wins. Previous lab-based studies have reported that participants tend to overestimate genuine wins when LDWs are present. This study reports an independent replication of these findings in a large online sample that included a substantial number of individuals reporting high-risk gambling and frequent EGM users., Methods: This online study recruited a sample of 940 participants who were randomly assigned to view one of two brief videos. Each video displayed a short period of simulated online slot machine gambling and included 2 genuine wins and either 3 or 0 LDWs. Participants were asked to estimate the number of times a win occurred that was more than the amount bet . Participants also completed the Problem Gambling Severity Index., Results: The mean estimated number of genuine wins was significantly larger for the condition displaying LDWs, 3.02 [95% CI = 2.82, 3.21] than the control condition, 2.14 [1.98, 2.30], t (887.66) = 6.78, d = 0.44, p <.001., Conclusions: We replicated the LDW-triggered win overestimation effect previously reported in lab-based experiments that have recruited smaller samples. This effect was robust in both low-risk and high-risk groups, indicating that even experienced gamblers remain susceptible. Exploratory modelling suggested only a minority of individuals were uninfluenced by LDWs., Competing Interests: The authors declare that they have no conflict of interest in relation to the publication of this article.

- Abstract
Introduction: Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for their analgesic and anti-inflammatory action, but the gastrointestinal (GI) adverse effects are a known cause of preventable harm. A medication safety audit was incentivised for community pharmacies in England in 2 successive years as part of the Pharmacy Quality Scheme (PQS) to address GI safety of NSAIDs., Aims: To evaluate community pharmacy's contributions to NSAID safety and determine any change between audit 1 (2018-2019) and audit 2 (2019-2020)., Method: Patients aged 65 years or over prescribed an NSAID were included in both audits. The audit tool assessed compliance with national standards relating to co-prescribed gastroprotection, referrals to the prescriber and patient advice on long-term NSAID use and effects, with responses submitted via an online portal. Descriptive analyses were performed to explore differences between the years and tested for significance using Χ
2 tests. Qualitative data were analysed using an inductive thematic approach., Key Findings: Data from 91 252 patients in audit 1 and 73 992 in audit 2 were analysed. More patients were prescribed gastroprotection in audit 2 (85.0%) than audit 1 (80.7%, p<0.001). More patients without gastroprotection in audit 2 had a current or recent referral (67.5%) than in audit 1 (58.8%, p<0.001). Verbal or other communications between pharmacists and patients about their NSAID medication were reported more frequently in audit 2 (76.0% vs 63.5%, p<0.001)., Conclusion: During two audits, community pharmacists in England reported referring more than 15 000 patients at risk of preventable harm from NSAIDs to prescribers for review. The audits demonstrated significant potential for year-on-year improvement in GI safety for a large cohort of older patients prescribed NSAIDs. This evaluation provides evidence of how the PQS can effectively address a specific aspect of medicines safety and the place of community pharmacy more broadly in improving medicines safety., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

- Abstract
Background: Commercial determinants of health (CDoH) represent a critical frame for exploring undue corporate and commercial influence over health. Power lenses are integral to understanding CDoH. Impacts of food, alcohol, and gambling industries are observable CDoH outcomes. This study aims to inform understanding of the systems and institutions of commercial and/or corporate forces working within the Australian food, alcohol, and gambling industries that influence health and well-being, including broader discourses materialised via these systems and institutions., Methods: Twenty semi-structured interviews were conducted with key-informants on Australian public policy processes. Interviewees were current and former politicians, political staff members, regulators and other public servants, industry representatives, lobbyists, journalists, and researchers with expertise and experience of the Australian food, alcohol, and/ or gambling industries. Interviews sought participants' perceptions of Australian food, alcohol, and gambling industries' similarities and differences, power and influence, relationships, and intervention opportunities and needs., Results: Strategies and tactics used by Australian food, alcohol and gambling industries are similar, and similar to those of the tobacco industry. They wield considerable soft (eg, persuasive, preference-shaping) and hard (eg, coercive, political, and legal/economic) power. Perceptions of this power differed considerably according to participants' backgrounds. Participants framed their understanding of necessary interventions using orthodox neoliberal discourses, including limiting the role of government, emphasising education, consumer freedom, and personal choice., Conclusion: Food, alcohol, and gambling industries exercise powerful influences in Australian public policy processes, affecting population health and well-being. Per Wood and colleagues' framework, these manifest corporate, social, and ecological outcomes, and represent considerable instrumental, structural, and discursive power. We identify power as arising from discourse and material resources alike, along with relationships and complex industry networks. Addressing power is essential for reducing CDoH harms. Disrupting orthodox discourses and ideologies underpinning this should be a core focus of public health (PH) advocates and researchers alike., (© 2023 The Author(s); Published by Kerman University of Medical Sciences This is an open-access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.)

- Abstract
Five patients, comprising nine treatment courses of sargramostim use in pulmonary alveolar proteinosis, are described. The prevailing standard of treatment, whole lung lavage (WLL), is highly invasive, resource intensive and carries some procedural risk. Nebulised recombinant human GM-CSF (sargramostim) offers a pharmacological treatment option, allowing patients to be treated at home, possessing potential advantages in patient experience and wider health resourcing. The majority of reported patients described subjective improvement in symptoms along with radiographical improvement, although this did not translate into significant improvement in pulmonary function testing. Drug scarcity and high drug cost remain potential barriers to accessing this treatment, and so careful patient selection and treatment outcome assessment remain as challenging needs. Incorporating the routine assessment of validated patient symptom scores with objective physiological measures will allow prediction of response to treatment and help guide management. This report describes the largest published experience of sargramostim use in Australia., (© 2022 British Pharmacological Society.)

Background and Aims: Homelessness is one of the most significant harms associated with gambling and appears to affect older adults disproportionately, but the relationship has received little research attention. This exploratory study investigated how gambling and homelessness is linked in older adults., Methods: Using qualitative research methods, we undertook in-depth semi structured face-to-face individual and group interviews to gather data from a purposive sample (n = 48) of key informants working in service provision for older adults (aged 50+ years) experiencing gambling-related harm and/or homelessness in Victoria, Australia. Thematic analysis of data focused on evaluating mechanisms and identifying contextual conditions that activate pathways between gambling and homelessness., Results: The relationship between gambling and homelessness in older adults is often indirect and non-linear, and can represent a reflexive cycle. Experiencing periods of homelessness into older age can contribute to gambling, often because the adverse impacts of homelessness on older adults' mental and material wellbeing increase the appeal of gambling. Additionally, comorbidities (e.g. substance use, mental illness, past trauma) and structural conditions (e.g. gambling accessibility, poverty, housing insecurity) can activate gambling. Furthermore, because gambling in the older homeless adult population is frequently hidden and regularly overlooked by service providers, it often continues unabated. Gambling in older adults can also contribute to the onset of first-time homelessness. Large and rapid losses from high-intensity gambling frequently characterize this route to homelessness. Such gambling is often triggered by major life events and changes (e.g. bereavement, job loss, relationship difficulties), and the outcomes are often worsened by the conduct of gambling operators and creditors., Conclusions: The link between gambling and homelessness in older adults is complex, with connecting mechanisms often contingent upon individual, interpersonal and structural conditions and contexts. There is potential for preventative and ameliorative action given many of the underlying conditions appear modifiable through policy intervention., (© 2021 Society for the Study of Addiction.)

- Abstract
Introduction: There is growing concern internationally about co-occurring gambling and homelessness. We systematically review prevalence estimates in help-seeking and community samples., Methods: Adopting PRISMA guidelines, we searched CINAHL Plus, Cochrane Library, Embase, Ovid MEDLINE, PsychINFO, Proquest Central, PubMed, Scopus, Web of Science, and Google Scholar for relevant peer-reviewed articles in English. Primary outcomes examined in narrative and quantitative syntheses included prevalence of: (i) gambling in persons experiencing homelessness; (ii) harmful gambling in persons experiencing homelessness; and, (iii) homelessness in persons experiencing harmful gambling., Results: Searches identified 917 records after removing duplicates. After screening, 45 articles providing 54 prevalence estimates across 12 countries were included, with help-seeking (k = 37) and community based sample (k = 8) estimates pooled separately. Gambling prevalence (all timeframes) in help-seeking samples of persons experiencing homelessness is low (28.7%, 95% CI: 17.3-41.7, k = 14) compared to the general population (approximately 60-80%). However, harmful gambling prevalence (including problem, pathological, and disordered gambling) in help-seeking samples of persons experiencing homelessness is high (16.5%, 95% CI: 10.2-24.2, k = 20) compared to the general population (approximately 1-7%). Additionally, homelessness prevalence is high in help-seeking samples of persons experiencing harmful gambling (23.6%, 95% CI: 18.4-29.2, k = 4) compared to the general population (<1%). Meta-analysis found high between-study heterogeneity and risk of bias from small samples sizes., Conclusions: There are high rates of harmful gambling in persons experiencing homelessness and, concurrently, high rates of homelessness in persons experiencing harmful gambling. Improvements in sampling and measurement are needed to strengthen robustness and generalizability of prevalence estimates, which can potentially inform the scale and targeting of clinical interventions, support services, and policy responses., (Copyright © 2021 Elsevier Ltd.

- Abstract
Background: Stigma is a social process that impedes access to support for mental health conditions and alcohol and other drug (AOD) use, particularly for people from migrant and ethnic minority backgrounds. There is limited understanding, however, of people's experiences of stigma, the underlying drivers, intersections with ethnicity, gender, and citizenship status, and how powerful discourses and social institutions create and perpetuate systems of stigma. This review aims to synthesise and critically analyse qualitative evidence to understand how stigma associated with mental health conditions and AOD use operates among people from migrant and ethnic minority groups., Methods: Qualitative evidence will be identified using MEDLINE, Embase, PsycINFO, CINAHL, Applied Social Sciences Index and Sociological Abstracts. Two reviewers will screen the titles, abstracts and full-text articles. Eligible studies will include original, empirical, peer-reviewed qualitative evidence, published in English since 1990. Studies must examine stigma in relation to mental health conditions, illicit drug use or alcohol consumption among participants who are from migrant and ethnic minority backgrounds. Studies will be critically appraised using the Joanna Briggs Institute Critical Appraisal Checklist for qualitative studies and the level of confidence in the findings will be assessed using Confidence in the Evidence from Reviews of Qualitative research. Data will be analysed using the 'best fit' framework synthesis approach, drawing on the Health Stigma and Discrimination Framework., Discussion: This review will provide an in-depth understanding of the stigma associated with mental health conditions and AOD use among people from migrant and ethnic minority backgrounds. The findings will inform culturally responsive interventions that aim to reduce the negative impact of stigma on individuals, families and communities., Systematic Review Registration: PROSPERO CRD42021204057., (© 2022.

- Abstract
Purpose: Comprehensive primary health care (PHC) models are seldom implemented in high income countries, in part due to their contested legitimacy in neoliberal policy environments. This article explores how merging affected the perceived legitimacy of independent community health organisations in Victoria, Australia, in providing comprehensive PHC services., Design/methodology/approach: A longitudinal follow-up study (2-3 years post-merger) of two amalgamations among independent community health organisations from the state of Victoria, Australia, was conducted. This article explores the perceived effects of merging on (1) the pragmatic, normative and cognitive legitimacy of studied organisations and (2) the collective legitimacy of these organisations in Victoria's health care system. Data were collected through 19 semi-structured interviews with key informants and subjected to template and thematic analyses., Findings: Merging enabled individual organisations to gain greater overall legitimacy as regional providers of comprehensive PHC services and thus retain some capacity to operationalise a social model of health. Normative legitimacy was most enhanced by merging, through acquisition of a large organisational size and adoption of business practices favoured by neoliberal norms. However, mergers may have destabilised the already contested cognitive legitimacy of community health services as a group of organisations and as a comprehensible state-wide platform of service delivery., Practical Implications: Over-reliance on individual organisational behaviour to maintain the legitimacy of comprehensive PHC as a model of organising health and social care could lead to inequities in access to such models across communities., Originality/value: This study shows that organisations can manage their perceived legitimacy in order to ensure the survival of their preferred model of service delivery., (© Emerald Publishing Limited.)

- Abstract
Objective: To analyse a 'socioecological' health promotion discourse and its relationship to orthodox 'economistic' discourse in Australia., Method: In research on health promotion addressing equity and environmental sustainability, we identified a socioecological discourse, based on an ethic of care for people and ecosystems. Using Foucault's concept of discourse as a regime that produces and legitimises certain kinds of knowledge, and ecofeminist historical analysis, we analysed this discourse and its relationship to economism., Results: The socioecological discourse takes social and ecological wellbeing as primary values, while economism takes production and trade of goods and services, measured by money, as primary. Following British invasion, property-owning white men in Australia had the right to control and profit from land, trade, and the work of women and subordinate peoples. A knowledge regime using money as a primary measure reflects this history. In contrast, a First Nations' primary value expressed in the study was 'look after the land and the children'. Conclusion and implications for public health: Public health often attempts to express value through economism, using monetary measures. However, socioecological discourse, expressed for example through direct measures of social and ecological wellbeing, appears more fit for purpose in promoting a fair and sustainable society., (© 2021 The Authors.)

- Abstract
Background Anticoagulants continue to pose high risk of harm to patients despite the discovery of novel direct-acting oral anticoagulant agents that require less monitoring than warfarin. Objective To evaluate patients' knowledge about their oral anticoagulants and the potential role for community pharmacists in optimising safety. Setting Community pharmacies in England. Methods An online survey-based evaluation conducted over a 5-month period to ascertain patients' knowledge, use of anticoagulant alert cards, compliance with national monitoring requirements for warfarin, and frequency and nature of community pharmacist involvement in optimisation. Differences between patients on direct-acting oral anticoagulant agents and warfarin were assessed using Chi squared tests. Main outcome measure Patients' knowledge and use of anticoagulant alert cards. Results A total of 1515 pharmacies participated. Of 22,624 patients, 97% knew that they were taking anticoagulants; 20% had alert cards with them at time of dispensing; 17% had no card and 10% refuted their usefulness. Patients on warfarin were more aware of interactions with over-the-counter or herbal medicines than those on direct-acting oral anticoagulant agents. Of the patients on warfarin, 82% confirmed monitoring in the previous 12 weeks in accordance with national standards, with the international normalised ratio value known for 76%. Pharmacists intervened in a fifth of the patients to issue an alert card, contact the general practitioner for a change in the prescription or due to interacting medicines. Conclusion Patients had reasonable knowledge of their anticoagulation therapy, but areas for improvement were identified. Community pharmacists are well placed to optimise the safe use of anticoagulants.

- Abstract
The gambling industry has grown into a global business in the 21st century. This has created the need for a new emphasis on problem prevention. This article highlights the core themes of the book Setting Limits: Gambling, Science and Public Policy, taking a broad view of the consequences of gambling for society as a burden on health, well-being and equality. The book covers the extent of gambling and gambling-related problems in different societies and presents a critical review of research on industry practices, policy objectives and preventive approaches, including services to people suffering from gambling and its consequences. It discusses the developments in game characteristics and gambling environments and provides evidence on how regulation can affect those. Effective measures to minimize gambling harm exist and many are well supported by scientific evidence. They include restrictions on general availability as well as selective measures to prevent gamblers from overspending. The revenue generated from gambling for the industry, governments, and providers of public services funded from gambling returns presents an obstacle to developing policies to implement harm-reduction measures. A public interest approach must weigh these interests against the suffering and losses of the victims of gambling., (© 2020 Society for the Study of Addiction.)

- Abstract
Time-limited prevention initiatives are frequently used to address complex and persisting public health issues, such as non-communicable diseases. This often creates issues in terms of achieving sustainable change. In this study, we use a system dynamic perspective to explore the effects of stop-start funding over system behaviour in two community-based initiatives designed to prevent chronic diseases and obesity. We conducted a qualitative exploratory study using complexity theory as an analytical lens of two Healthy Together Communities (HTCs) initiatives in Victoria, Australia. Data were generated from 20 semi-structured interviews with health promotion practitioners and managers, from community health and local government organizations. Template analysis based on properties of complex systems informed the inductive identification of system behaviour narratives across the stop-start life-course of HTCs. A central narrative of system behaviour emerged around relationships. Within it, we identified pre-existing contextual conditions and intervention design elements that influenced non-linearity of system self-organization and adaptation, and emergence of outcomes. Examples include cynicism, personal relationships and trust, and history of collaboration. Feedback loops operated between HTCs and these conditions, in a way that could influence long-term system behaviour. Taking a dynamic life-course view of system behaviour helps understand the pre-existing contextual factors, design and implementation influences, and feedback loops which shape the long-term legacy of short-lived interventions aimed at solving complex issues. In turn, greater awareness of such interactions can inform better design and implementation of community-based interventions., (© The Author(s) 2019. Published by Oxford University Press.

- Abstract
Complexity and systems science are increasingly used to devise interventions to address health and social problems. Boundaries are important in systems thinking, as they bring attention to the power dynamics that guide decision-making around the framing of a situation, and how it is subsequently tackled. Using complexity theory as an analytical frame, this qualitative exploratory study examined boundary interactions between local government and community health organizations during the operationalization of a systems-based initiative to prevent obesity and chronic diseases (Healthy Together Communities-HTCs) in Victoria, Australia. Across two HTC sites, data was generated through semi-structured interviews with 20 key informants, in mid-2015. Template analysis based on properties of complex systems was applied to the data. The dynamics of boundary work are explored using three case illustrations: alignment, boundary spanning and boundary permeability. Alignment was both a process and an outcome of boundary work, and occurred at strategic, operational and individual levels. Boundary spanning was an important mechanism to develop a unified collaborative approach, and ensure that mainstream initiatives reached disadvantaged groups. Finally, some boundaries exhibited different levels of permeability for local government and community health organizations. This influenced how each organization could contribute to HTC interventions in unique, yet complementary ways. The study of boundary work offers potential for understanding the mechanisms that contribute to the nonlinear behaviour of complex systems. The complementarity of partnering organizations, and boundary dynamics should be considered when designing and operationalizing multilevel, complex systems-informed prevention initiatives., (© The Author(s) 2019.

- Abstract
Objectives: To address the current status of responsible gambling (RG) as the dominant discourse for reducing gambling harm., Study Design: The article is a narrative review of relevant literature analysed discursively., Methods: We identified significant texts describing the discourse of RG and analysed these to extract major characteristics and themes of the discourse. These were then subjected to a critique, using the public health discourses as an alternative system for addressing gambling harm., Results: The discourse of RG is inadequate for preventing or minimising gambling harm. A public health-focused approach to prevent and minimise gambling harm is likely to be far more effective but will be opposed by vested interests., Conclusions: It is timely to consider abandoning the discourse of RG. This discourse has been discredited because of its complicity with vested interests and a lack of evidence to demonstrate its efficacy in preventing or reducing harm. A public health response to the prevention of gambling harm is feasible and practical and can and should be further developed and implemented rapidly., (Copyright © 2020 The Royal Society for Public Health.

- Abstract
Background: Despite increasing attention to the social determinants of health in recent decades, globally there is an unprecedented burden from non-communicable diseases (NCDs). Recently, the corporate and commercial conditions associated with these, commercial determinants of health (CDoH), have also begun to receive attention. This research aims to articulate the CDoH as described in the literature, summarize substantive findings, and assess strengths and limitations of current literature., Methods: Systematic review of formal (Medline, EMBASE, Scopus, Global Health) and grey literature (database, Google Advanced, targeted website, citation searching). Searching identified 125 texts for full-text review, with 33 included for final review. Data extracted were analyzed thematically., Results: The dynamics constituting CDoH include broad facilitators such as globalization of trade, corporate structures, and regulatory systems, articulation of social and economic power, neoliberal and capitalist ideologies; additional elements include corporate activities such as marketing, corporate political activities, corporate social responsibility, extensive supply chains, harmful products and production, and issues of accessibility. These contribute significantly to worsened global health outcomes., Conclusions: Literature describing effects of macro conditions and corporate activities on health could usefully utilize CDoH terminology. Facilitation via revised, consistent and operational definition of CDoH would assist. Social, political, commercial and economic structures and relations of CDoH are under-theorized. Systematic approaches to identifying, describing, and disrupting these are required to improve global health.

- Abstract
Background: Electronic gambling machines (EGMs) are in casinos and community venues (hotels and clubs) in all jurisdictions in Australia, except Western Australia (only in casino). EGMs have a range of features that can affect how people gamble, which can influence losses incurred by users. The Northern Territory Government recently changed two EGM policies - the introduction of note acceptors on EGMs in community venues, and an increase in the cap from 10 to 20 EGMs in hotels and 45 to 55 in clubs. This study evaluates two changes in EGM policy on user losses in community venues, and tracks changes in user losses per adult, EGM gambler, and EGM problem/moderate risk gambler between 2005 and 2015., Methods: Trends in venue numbers, EGM numbers, user losses and user losses per EGM by venue type and size are presented to determine if EGM policy changes affected user losses. Data from the 2005 and 2015 NT gambling surveys are used to determine EGM user losses per adult, per EGM gambler, and per EGM problem and/or moderate risk gambler, with several assumptions applied., Results: From 2010 (post smoking ban) to 2013 real user losses were stagnant, but from 2013 to 2017, real user losses in community venues increased 19, 9, 8 and 5% per annum, with increases higher in clubs and hotels with the maximum allowable number of EGMs. Over the same period user losses in the two casinos declined by 13%. Between 2005 and 2015, estimated user losses per EGM problem/moderate risk and problem gambler increased by 5 and 34% respectively., Conclusions: The analysis demonstrates that reductions in how much money gamblers can insert into an EGM (load-up limit), and/or the abolition of note acceptors, and reductions in the number of EGMs in venues is likely to reduce harm from EGM use. Given the demonstrated inability for Australian jurisdictions to identify and implement effective harm prevention and minimisation interventions, a national approach to gambling regulation in Australia may be desirable. Similarly, national co-ordination of research, particularly on EGMs and online betting is required to better understand changes in gambling policy on related harms.

- Abstract
Comprehensive theories of health justice can supplement rights-based approaches like primary health care, by conceptualizing key terms, and systematizing knowledge about structural factors that influence health. Our aim was to use "health capability" as a theoretical lens for understanding how primary health care approaches might address structural factors impeding health in a rural Swazi community. We conducted abductive, interpretive, analysis of a mixed-method (QUAL+quan) data set about "health capability deprivations," generated through participatory action research. Four themes are discussed: illness and disease, unhealthy daily living environments, inability to move freely, and gendered expectations and norms. The analysis demonstrates that there were complex interrelationships between health capability deprivations, material and ideological deprivation prevented community members from aspiring to or securing their right to health, health capability theory can augment primary health care approaches and vice versa, and qualitatively driven, mixed-method research can generate unique insights about structural factors that influence health.
