INTRODUCTION: There is growing concern over the lack of regulation of alcohol advertisements on social media platforms frequented by youths. This study aims to build upon existing literature by assessing the frequency with which young Australians (17-25) are shown advertisements promoting alcohol use and the themes utilised in these advertisements. METHODS: A total of 125 Australian youths (mean age 18.74 years; 74.40% female) were recruited in exchange for course credit to participate in an online study. Participants scrolled through Facebook or Instagram for a period of 30 min and screenshotted any alcohol advertisements encountered. Participants then identified the advertisement qualities (or 'themes') present in the advertisements, based on pre-identified categories. Demographic, social media usage and historical personal, peer or familial substance use behaviour data was also collected. RESULTS: Seventy-one university students were exposed to 796 alcohol advertisements across both platforms, and they encountered an advertisement every 2 min and 43 s on average. Most advertisements included call to action features on both Facebook (78.80%) and Instagram (71.17%). Advertisements relating to ease of access (promoting subscription/home delivery; 41.72% and 42.56%) and sales incentives (special offers, promotions, samples or bonuses with purchase; 43.70% and 46.84%) were most common across both platforms. DISCUSSION AND CONCLUSIONS: Alcohol advertisements are highly prevalent online, particularly among Australian youth social media users. Future research should endeavour to identify whether temporal use of alcohol is a predictor of subsequent exposure to alcohol advertising on social media, and whether this exposure is likely to increase successive alcohol use behaviours.

BACKGROUND: Abrocitinib, an oral, once-daily, Janus kinase 1-selective inhibitor, is efficacious in moderate-to-severe atopic dermatitis with a manageable long-term safety profile. OBJECTIVE: We aimed to provide updated integrated long-term safety results for abrocitinib from available data accrued up to a maximum of almost 4 years in patients with moderate-to-severe atopic dermatitis from the JADE clinical development program. METHODS: Analysis included 3802 patients (exposure: 5213.9 patient-years) from the phase II monotherapy study (NCT02780167) and the phase III studies JADE MONO-1 (NCT03349060), JADE MONO-2 (NCT03575871), JADE TEEN (NCT03796676), JADE COMPARE (NCT03720470), JADE DARE (NCT04345367; 200 mg only), JADE REGIMEN (NCT03627767), and JADE EXTEND (NCT03422822; data cutoff 25 September, 2021). Data from patients receiving one or more doses of abrocitinib 200 mg or 100 mg were pooled in a consistent-dose cohort (patients were allocated to receive the same abrocitinib dose throughout exposure in the qualifying parent study and/or long-term study) or a variable-dose cohort (patients received open-label abrocitinib 200 mg; responders were randomized to abrocitinib 200 mg, 100 mg, or placebo, and could then receive abrocitinib 200 mg plus topical corticosteroids as rescue therapy). Incidence rates of adverse events of special interest were assessed. Cox regression analysis of risk factors for herpes zoster and serious infections was performed. RESULTS: Overall, this safety analysis of long-term data up to a maximum of ~ 4 years of abrocitinib exposure does not indicate any changes from the previously reported risk profile. The most frequent serious infections (per Medical Dictionary for Regulatory Activities preferred term) with consistent-dose abrocitinib 200 mg and 100 mg were herpes zoster (0.5% and 0.2%), pneumonia (0.2% with either dose), and herpes simplex (0.1% with either dose). Risk factors for herpes zoster were a history of herpes zoster, abrocitinib 200-mg dose, age ≥ 65 years, absolute lymphocyte count < 1 × 103/mm3 before the event, and residing in Asia. For serious infections, > 100 kg body weight was a risk factor. Incidence rate/100 patient-years (95% confidence interval) with the consistent abrocitinib 200-mg and 100-mg dose combined was higher in older (aged ≥ 65 years) patients versus younger (aged 18 to < 65 years) patients for serious adverse events (17.6 [11.7‒25.4] vs 6.7 [5.8‒7.8]), malignancy excluding non-melanoma skin cancer (2.4 [0.6‒6.0] vs 0.1 [0.0‒0.4]), non-melanoma skin cancer (2.4 [0.6‒6.1] vs 0.2 [0.1‒0.4]), lymphopenia (3.5 [1.3‒7.6] vs 0.1 [0.0‒0.3]), and venous thromboembolism (1.7 [0.4‒5.1] vs 0.1 [0.0‒0.3]). Incident rate/100 patient-years (95% confidence interval) of non-melanoma skin cancer with the consistent abrocitinib 200-mg and 100-mg dose combined was higher in current/former smokers (0.9 [0.4‒1.6]) vs never-smokers (0.0 [0.0‒0.1]). CONCLUSIONS: This safety update showed a consistent profile for abrocitinib with no new safety signals and continues to support that abrocitinib has a manageable long-term safety profile in patients with moderate-to-severe atopic dermatitis. Risk of specific adverse events was higher in certain patient populations, especially those aged ≥ 65 years.

Abrocitinib is an approved treatment for people with moderate or severe atopic dermatitis, also known as AD or atopic eczema. Abrocitinib is a tablet that is taken by mouth once a day. This safety analysis looked at the side effects of treatment in a large group of adults and adolescents with moderate or severe AD who took abrocitinib up to a maximum of almost 4 years. This analysis also looked at which people were more likely to have certain side effects after taking abrocitinib. The results from this analysis were similar to those of previous safety analyses with abrocitinib, with no new side effects. Infections such as shingles, pneumonia, or herpes simplex can occur during treatment with abrocitinib. Shingles was more likely to occur in people who previously had shingles before taking abrocitinib, or who took the higher dose of abrocitinib (200 mg), or were 65 years of age or older, or had certain blood test results, or lived in Asia. People who are 65 years of age or older and took abrocitinib were more likely to develop some types of cancer, have certain abnormal blood test results, or develop blood clots in the veins than people with AD who were younger and took abrocitinib. Current or former smokers with AD who took abrocitinib were more likely to develop skin cancer (but not melanoma) than people with AD who took abrocitinib but have never smoked. This analysis further shows that abrocitinib had manageable safety in patients with moderate-to-severe AD.

INTRODUCTION: Early prediction of abrocitinib efficacy in atopic dermatitis (AD) could help identify candidates for an early dose increase. A predictive model determined week 12 efficacy based on week 4 responses in patients receiving abrocitinib 100 mg/day and assessed the effect of an abrocitinib dose increase on platelet counts. METHODS: Analysis included the phase 3 trials JADE MONO-1 (NCT03349060), MONO-2 (NCT03575871), COMPARE (NCT03720470), and TEEN (NCT03796676). For platelet counts and simulations, a phase 2 psoriasis trial (NCT02201524) and phase 2b (NCT02780167) and phase 3 (MONO-1, MONO-2, and REGIMEN (NCT03627767)) abrocitinib trials were pooled. A training-and-validation framework assessed potential predictors of response at week 4: score and score change from baseline in the Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), and Peak Pruritus Numerical Rating Scale (PP-NRS), and percentage change from baseline in EASI. The dependent variables at week 12 were ≥ 75% improvement in EASI (EASI-75) and IGA score of 0 (clear) or 1 (almost clear) and ≥ 2-point improvement from baseline. The probability of each variable to predict week 12 EASI-75 and IGA responses was calculated. RESULTS: In the training cohort (n = 453), 72% of the ≥ 50% improvement in EASI (EASI-50) at week 4 responders and 16% of the nonresponders with abrocitinib 100 mg achieved EASI-75 at week 12; 48% and 6% of the week 4 EASI-50 responders and nonresponders, respectively, achieved week 12 IGA response. Similar results occurred with week 4 IGA = 2, ≥ 4-point improvement from baseline in PP-NRS, or EASI = 8 responders/nonresponders. Platelet counts after an abrocitinib dose increase from 100 to 200 mg were similar to those seen with continuous dosing with abrocitinib 100 mg or 200 mg. CONCLUSION: Achieving week 4 clinical responses with abrocitinib 100 mg may be useful in predicting week 12 responses. Week 4 nonresponders may benefit from a dose increase to abrocitinib 200 mg, and those that receive this dose increase are likely to achieve treatment success at week 12, with no significant impact on platelet count recovery. Video abstract available for this article. CLINICAL TRIAL REGISTRATION: NCT03349060, NCT03575871, NCT03720470, NCT03796676, NCT02201524, NCT02780167 and NCT03627767.


Abrocitinib is an approved treatment for people with moderate or severe atopic dermatitis. Abrocitinib tablets are available in two doses (100 and 200 mg) and are taken by mouth once daily. Some people with atopic dermatitis who are taking abrocitinib 100 mg may need to increase the dose to 200 mg to get adequate symptom relief. We studied whether people with atopic dermatitis who did or did not experience clear skin or itch relief after taking abrocitinib 100 mg for 4 weeks are likely or not likely to experience relief after 12 weeks of treatment. We also defined the level of response after 4 weeks of treatment that best differentiates people who did or did not experience symptom relief, and we identified who might benefit from increasing the abrocitinib dose from 100 to 200 mg. We found that people with atopic dermatitis who had symptom relief after 4 weeks of abrocitinib 100 mg treatment were much more likely to have greater relief after 12 weeks, and people who did not achieve symptom relief after 4 weeks may benefit from a dose increase at week 4. Some people who receive abrocitinib 200 mg may have a temporary decrease in the number of certain blood cells called platelets at week 4, but platelets return to near-normal levels by week 12. This analysis showed that increasing the abrocitinib dose from 100 to 200 mg at week 4 did not seem to affect the platelet numbers after week 4. Video abstract (MP4 174529 KB).

Australia prohibits the sale of nicotine-vaping products unless prescribed by medical practitioners. Significant policy reforms were announced on the 28th of November 2023 including a ban on single-use disposable vapes with and without nicotine, and the removal of the personal importation scheme. Despite stringent regulations, loopholes exist such that e-cigarette vendors are getting around it, and online markets provide a route to do so. We discuss strategies used by vendors to covertly market e-cigarettes online through social media. In this perspective, we highlight three proposed policies to strengthen social media regulations that may be feasible to implement. Our proposed strategies to regulate e-cigarette product listings on social media involve implementing robust age verification measures, enhancing the system for flagging and reporting prohibited content, and developing a more effective system to identify and flag content related to e-cigarettes.

PURPOSE OF REVIEW: This review describes the diagnoses related to problem gaming that are included in ICD-11, published by the WHO in 2022. It summarizes the recent literature on the prevalence of Gaming Disorder, its structure, antecedents and comorbidities, and explores whether the range of diagnoses currently available adequately covers the range of experiences seen with problem gaming. RECENT FINDINGS: Overall, between 3 and 6% of the population worldwide are reported to have a gaming disorder as defined by ICD-11 or DSM-5. However, most studies are constrained by methodological issues such as nonrepresentative samples and the use of brief questionnaires to determine prevalence. ICD-11 Gaming Disorder is a psychometrically sound diagnosis. There is no diagnosis that currently captures the experience of harm from gaming, where the requirements for the diagnosis of Gaming Disorder are not reached. SUMMARY: There is evidence in support of the proposed new entity of 'Harmful Gaming', which encompasses mental and physical harm/impairment due to a repeated pattern of gaming, but where requirements for the diagnosis of Gaming Disorder are not met. Such a diagnosis would complete the spectrum of diagnoses available for problem or unhealthy gaming, similar to those for unhealthy substance use, and would provide a framework for a public health approach to reducing the overall harm from unhealthy gaming.

BACKGROUND: Diabetes leads to chronic kidney disease (CKD) and kidney failure, requiring dialysis or transplantation. Astragalus, a common herbal medicine and US pharmacopeia-registered food ingredient, is shown kidney protective by retrospective and preclinical data but with limited long-term prospective clinical evidence. This trial aimed to assess the effectiveness of astragalus on kidney function decline in macroalbuminuric diabetic CKD patients. METHODS: This randomized, assessor-blind, standard care-controlled, multi-center clinical trial randomly assigned 118 patients with estimated glomerular filtration rate (eGFR) of 30-90 ml/min/1.73m2 and urinary albumin-to-creatinine ratio (UACR) of 300-5000 mg/g from 7 public outpatient clinics and the community in Hong Kong between July 2018 and April 2022 to add-on oral astragalus granules (15 gs of raw herbs daily equivalent) or to continue standard care alone as control for 48 weeks. Primary outcomes were the slope of change of eGFR (used for sample size calculation) and UACR of the intention-to-treat population. Secondary outcomes included endpoint blood pressures, biochemistry, biomarkers, concomitant drug change and adverse events. (ClinicalTrials.gov: NCT03535935) RESULTS: During the 48-week period, the estimated difference in the slope of eGFR decline was 4.6 ml/min/1.73m2 per year (95 %CI: 1.5 to 7.6, p = 0.003) slower with astragalus. For UACR, the estimated inter-group proportional difference in the slope of change was insignificant (1.14, 95 %CI: 0.85 to 1.52, p = 0.392). 117 adverse events from 31 astragalus-treated patients and 41 standard care-controlled patients were documented. The 48-week endpoint systolic blood pressure was 7.9 mmHg lower (95 %CI: -12.9 to -2.8, p = 0.003) in the astragalus-treated patients. 113 (96 %) and 107 (91 %) patients had post-randomization and endpoint primary outcome measures, respectively. CONCLUSION: In patients with type 2 diabetes, stage 2 to 3 CKD and macroalbuminuria, add-on astragalus for 48 weeks further stabilized kidney function on top of standard care.

BACKGROUND AND AIMS: Population-level alcohol use data are available from high-income countries, but limited research has been conducted in sub-Saharan Africa. This systematic review and meta-analysis aimed to summarize population-level alcohol use in sub-Saharan Africa. METHOD: Databases searched included PubMed, EMBASE, PsycINFO and AJOL, without language restrictions. Searches were also conducted in the Global Health Data Exchange (GHDx) and Google Scholar. Search terms encompassed 'substance' or 'substance-related disorders' and 'prevalence' and 'sub-Saharan Africa'. We included general population studies on alcohol use (including any use, high-risk alcohol use and alcohol use disorders) from 2018 onwards. Prevalence data for alcohol use among sub-Saharan African adolescents (10-17) and adults (18+) were extracted. Analyses included life-time and past 12- and 6-month alcohol use. RESULTS: We included 141 papers. Among adolescents, the life-time prevalence of alcohol use was 23.3% [95% confidence interval (CI) = 11.3-37.1%], 36.2% (CI = 18.4-56.1%) in the past year and 11.3% (CI = 4.5-20.4%) in the past 6 months. Among adolescents, 12-month prevalence of alcohol use disorder and alcohol dependence were 7.7% (CI = 0.0-27.8%) and 4.1% (CI = 1.4-7.9%), respectively. Among adults, the life-time prevalence of alcohol use was 34.9% (CI = 17.7-54.1%), 27.1% (CI = 5.0-56.4%) in the past year and 32.2% (CI = 19.8-46.0%) in the past 6 months. Among adults, the 12-month prevalence of alcohol use disorder and alcohol dependence were 9.5% (CI = 0.0-30.4%) and 4.3% (CI = 0.8-9.8%), respectively. The highest weighted life-time prevalence of alcohol use, 86.4%, was reported in Tanzania among adults. The highest weighted past 6-month prevalence of alcohol use, 80.6%, was found in Zambia among adolescents. CONCLUSION: Alcohol use patterns vary across countries and subregions within sub-Saharan Africa, and comprehensive population-level data on alcohol use remain scarce in numerous sub-Saharan African countries. The prevalence of alcohol use disorder is common among adolescents in sub-Saharan Africa.

Prioritizing adolescent health is a public health priority to achieve the sustainable development goals, including reducing the risk of unsafe sex. Data on unsafe sex have remained scarce among adolescents in low-and middle-income countries (LMICs). To estimate the prevalence of unsafe sex in LMICs, we conducted secondary data analysis on the Global School-based Student Health Surveys among 244,863 students aged 13-17 years from 68 countries across five World Health Organization regions. The overall prevalence of ever had sex was 16.2%. The highest to lowest regional prevalence estimation of ever had sex was 30.5% (28.9-32.1) in the Americas, 28.6% (26.8-30.4) in Africa, 10.9% (9.2-12.6) in the Eastern Mediterranean, 9.6% (8.8-10.5) in South-East Asia, and 8.0% (6.8-9.1) in the Western Pacific. The highest prevalence of sexual intercourse before age 14 and practicing sexual intercourse without condom use were 36.5% (34.5-38.5) and 32.2% (30.1-34.3) in Africa, respectively. Findings suggest that current interventions are inadequate in promoting the uptake of safe sexual behaviors and an urgent intervention is needed.

BACKGROUND AND OBJECTIVE: Abrocitinib is an oral small-molecule Janus kinase (JAK)-1 inhibitor approved for the treatment of moderate-to-severe atopic dermatitis. In vitro studies indicated that abrocitinib is a weak time-dependent inhibitor of cytochrome P450 (CYP) 2C19/3A and a weak inducer of CYP1A2/2B6/2C19/3A. To assess the potential effect of abrocitinib on concomitant medications, drug-drug interaction (DDI) studies were conducted for abrocitinib with sensitive probe substrates of these CYP enzymes. The impact of abrocitinib on hormonal oral contraceptives (ethinyl estradiol and levonorgestrel), as substrates of CYP3A and important concomitant medications for female patients, was also evaluated. METHODS: Three Phase 1 DDI studies were performed to assess the impact of abrocitinib 200 mg once daily (QD) on the probe substrates of: (1) 1A2 (caffeine), 2B6 (efavirenz) and 2C19 (omeprazole) in a cocktail study; (2) 3A (midazolam); and (3) 3A (oral contraceptives). RESULTS: After multiple doses of abrocitinib 200 mg QD, there is a lack of effect on the pharmacokinetics of midazolam, efavirenz and contraceptives. Abrocitinib increased the area under the concentration time curve from 0 to infinity (AUCinf) and the maximum concentration (Cmax) of omeprazole by approximately 189 and 134%, respectively. Abrocitinib increased the AUCinf of caffeine by 40% with lack of effect on Cmax. CONCLUSIONS: Based on the study results, abrocitinib is a moderate inhibitor of CYP2C19. Caution should be exercised when using abrocitinib concomitantly with narrow therapeutic index medicines that are primarily metabolized by CYP2C19 enzyme. Abrocitinib is a mild inhibitor of CYP1A2; however, the impact is not clinically relevant, and no general dose adjustment is recommended for CYP1A2 substrates. Abrocitinib does not inhibit CYP3A or induce CYP1A2/2B6/2C19/3A and does not affect the pharmacokinetics of contraceptives.

BACKGROUND AND AIMS: Adolescent polysubstance use has been associated with adverse social and health outcomes. Our aim was to measure rates and transitions to polysubstance use during adolescence and identify factors associated with initiation and discontinuation of polysubstance use. DESIGN: Prospective cohort study. Multistate Markov modelling was used to estimate rates and identify correlates of transitions between substance use states. SETTING AND PARTICIPANTS: Adolescent-parent dyads (n = 1927; adolescents in grade 7, age ≈13 years) were recruited from Australian schools during 2010/11 (Wave 1). Adolescents were surveyed annually until 2016/17 (n = 1503; age ≈19 years; Wave 7) and parents were surveyed annually until 2014/15 (Wave 5). MEASUREMENTS: Alcohol, tobacco, cannabis and 3,4-methylenedioxymethamphetamine (MDMA) use outcomes were collected at Waves 3-7. Potential confounders were collected at Waves 1-6 and consisted of sex, anxiety and depression symptoms and externalizing problems, parental monitoring, family conflict and cohesion, parental substance use and peer substance use. Covariates were age and family socioeconomic status. FINDINGS: Few adolescents engaged in polysubstance use at earlier waves (Wave 3: 5%; Wave 4: 8%), but proportions increased sharply across adolescence (Waves 5-7: 17%, 24%, 36%). Rates of transitioning to polysubstance use increased with age, with few (<9%) adolescents transitioning out. More externalizing problems (odds ratio [OR] = 1.10; 99.6% confidence interval [CI] = 1.07-1.14), parental heavy episodic drinking (OR = 1.22; 99.6% CI = 1.07-1.40), parental illicit substance use (OR = 3.56; 99.6% CI = 1.43-8.86), peer alcohol use (OR = 5.68; 99.6% CI = 1.59-20.50) and peer smoking (OR = 4.18; 99.6% CI = 1.95-8.81) were associated with transitioning to polysubstance use. CONCLUSIONS: Polysubstance use in Australia appears to be rare during early adolescence but more common in later adolescence with low rates of transitioning out. Externalizing problems and greater parental and peer substance use are risk factors for adolescent polysubstance use that may be suitable intervention targets.

OBJECTIVE: To review randomised controlled trials (RCTs) investigating the effectiveness of text message-based interventions for smoking cessation, including the effects of dose (number of text messages) and concomitant use of behavioural or pharmacological interventions. DATA SOURCES: We searched seven databases (PubMed, CINAHL, PsycINFO, Scopus, EMBASE, Cochrane Library and Web of Science), Google Scholar and the reference lists of relevant publications for RCTs. Eligible studies included participants aged ≥15 years who smoked tobacco at enrolment. STUDY SELECTION: One reviewer screened titles and abstracts and two reviewers independently screened full texts of articles. DATA EXTRACTION: One of three reviewers independently extracted data on study and intervention characteristics and smoking abstinence rates using Qualtrics software. DATA SYNTHESIS: 30 of the 40 included studies reported higher rates of smoking cessation among those receiving text messaging interventions compared with comparators, but only 10 were statistically significant. A meta-analysis of seven RCTs found that participants receiving text messages were significantly more likely to quit smoking compared with participants in no/minimal intervention or 'usual care' conditions (risk ratio 1.87, 95% CI 1.52 to 2.29, p <0.001). Three trials found no benefit from a higher dose of text messages on smoking cessation. Two trials that tested the added benefit of text messaging to pharmacotherapy reported outcomes in favour of adding text messaging. CONCLUSIONS: Findings suggest that text messaging-based interventions are effective at promoting smoking cessation. Further research is required to establish if any additional benefit is gained from an increased number of text messages or concurrent pharmacotherapy or behavioural counselling.

BACKGROUND: Second-hand smoking (SHS) increases the risk of chronic disease in adults and poses a serious health threat to children. Mass media campaigns are instrumental in raising awareness and reducing SHS exposure. There is a need to identify recent SHS mass media campaigns and assess their sustainability in terms of knowledge, attitudes, and behavioural changes. This systematic review summarises the characteristics and outcomes of mass media campaigns on SHS prevention. METHODS: PubMed, Embase, Web of Science, and grey literature were searched in November 2022 for SHS campaigns implemented between 2016 and 2022. The eligibility criteria included campaigns on the dangers or effects of SHS with any target group, dissemination medium, study design, or language. The database search identified 1,413 peer-reviewed titles, of which 82 full-texts were screened, with 14 meeting the eligibility criteria. The grey literature search identified 9,807 sources, of which 61 were included. We extracted data on the campaign characteristics, metrics, and smoking-related outcomes. The JBI critical appraisal tool was used to assess the risk of bias of the included studies. RESULTS: We found 73 SHS campaigns conducted between 2002 and 2022, across 50 countries. The campaigns reached 378 million people. The reported recall rates range from 8 to 76%. Of the 11 studies that reported smoking-related outcomes, 10 reported increased knowledge in understanding SHS risks (73-85%), five reported an increased prevalence of smoke-free homes, and two reported an increase in number of participants persuading others to quit smoking. Two studies reported a decrease in overall smoking, whereas three studies observed a reduction in smoking in the presence of children. CONCLUSION: The available data provide some support for the effectiveness of SHS campaigns in reducing smoking behaviours in homes and around children. However, the certainty of evidence was low due to the lack of a control group and the substantial heterogeneity in the outcomes assessed. Future campaigns need comprehensive evaluation and reporting to reduce publication bias.

Randomized controlled trials (RCTs) are considered the gold standard for causal inference. With a sufficient sample size, randomization removes confounding up to the time of randomization and allows the treatment effect to be isolated. However, RCTs may have limited generalizability and transportability and are often not feasible in addiction research due to ethical or logistical constraints. The importance of observational studies from real-world settings has been increasingly recognized in research on health. This paper provides an overview of modern approaches to designing observational studies that enable causal inference. It illustrates three key techniques, Directed Acyclic Graphs (DAGs), modified Disjunctive Cause Criterion and Target Trial Emulation, and discusses the strengths and limitations of their applications.

Background: Conduction system pacing (CSP), either as His bundle pacing (HBP) or as left bundle branch area pacing (LBBAP), may be superior to right ventricular apical or septal pacing. Objective: The study sought to present acute results for a new guiding catheter (Biotronik Selectra 3D) designed for CSP implantations of a retractable screw-in lead (Biotronik Solia S). Methods: The primary endpoint of the prospective, international nonrandomized BIO|MASTER.Selectra 3D study was freedom from catheter-related serious adverse device effects (SADEs) within 1 week of lead implantation. Results: Of 157 enrolled patients, CSP was achieved in 147 (93.6%) patients. No SADEs occurred within 7 days. LBBAP was achieved in 82 patients (45 as crossover from an HBP attempt) and HBP in 65 (44.2%) patients. In centers considering both HBP and LBBAP, the CSP implantation success approached 99%. Successful CSP implantations lasted on average ∼50 minutes (fluoroscopy ∼6 minutes). Most procedures (87.9%) needed only 1 catheter, even after switch from HBP to LBBAP. The catheter's handling was rated largely positive. In patients without bundle branch block, mean QRS duration increased from 106 ms (intrinsic) to 122 ms (CSP) (P = .001). In patients with bundle branch block, mean QRS duration decreased from 151 ms (intrinsic) to 137 ms (CSP) (P = .004). Conclusion: The Selectra 3D catheter is a valuable tool for HBP and LBBAP implantations of the stylet-supported pacemaker leads. When implanters considered both HBP and LBBAP, the success rate was ∼99%. Flexibility to change between different approaches may be advisable in heterogeneous and challenging areas, such as CSP implantations.

Human cytomegalovirus (HCMV) utilizes peripheral blood monocytes as a means to systemically disseminate throughout the host. Following viral entry, HCMV stimulates non-canonical Akt signaling leading to the activation of mTORC1 and the subsequent translation of select antiapoptotic proteins within infected monocytes. However, the full extent to which the HCMV-initiated Akt/mTORC1 signaling axis reshapes the monocyte translatome is unclear. We found HCMV entry alone was able to stimulate widescale changes to mRNA translation levels and that inhibition of mTOR, a component of mTORC1, dramatically attenuated HCMV-induced protein synthesis. Although monocytes treated with normal myeloid growth factors also exhibited increased levels of translation, mTOR inhibition had no effect, suggesting HCMV activation of mTOR stimulates the acquisition of a unique translatome within infected monocytes. Indeed, polyribosomal profiling of HCMV-infected monocytes identified distinct prosurvival transcripts that were preferentially loaded with ribosomes when compared to growth factor-treated cells. Sirtuin 1 (SIRT1), a deacetylase that exerts prosurvival effects through regulation of the PI3K/Akt pathway, was found to be highly enriched following HCMV infection in an mTOR-dependent manner. Importantly, SIRT1 inhibition led to the death of HCMV-infected monocytes while having minimal effect on uninfected cells. SIRT1 also supported a positive feedback loop to sustain Akt/mTORC1 signaling following viral entry. Taken together, HCMV profoundly reshapes mRNA translation in an mTOR-dependent manner to enhance the synthesis of select factors necessary for the survival of infected monocytes.IMPORTANCEHuman cytomegalovirus (HCMV) infection is a significant cause of morbidity and mortality among the immunonaïve and immunocompromised. Peripheral blood monocytes are a major cell type responsible for disseminating the virus from the initial site of infection. In order for monocytes to mediate viral spread within the host, HCMV must subvert the naturally short lifespan of these cells. In this study, we performed polysomal profiling analysis, which demonstrated HCMV to globally redirect mRNA translation toward the synthesis of cellular prosurvival factors within infected monocytes. Specifically, HCMV entry into monocytes induced the translation of cellular SIRT1 to generate an antiapoptotic state. Defining the precise mechanisms through which HCMV stimulates survival will provide insight into novel anti-HCMV drugs able to target infected monocytes.

In the United States (US), biosafety and biosecurity oversight of research on viruses is being reappraised. Safety in virology research is paramount and oversight frameworks should be reviewed periodically. Changes should be made with care, however, to avoid impeding science that is essential for rapidly reducing and responding to pandemic threats as well as addressing more common challenges caused by infectious diseases. Decades of research uniquely positioned the US to be able to respond to the COVID-19 crisis with astounding speed, delivering life-saving vaccines within a year of identifying the virus. We should embolden and empower this strength, which is a vital part of protecting the health, economy, and security of US citizens. Herein, we offer our perspectives on priorities for revised rules governing virology research in the US.

INTRODUCTION: Medicinal cannabis is now legal in 44 US jurisdictions. Between 2020 and 2021 alone, four US jurisdictions legalised medicinal cannabis. The aim of this study is to identify themes in medicinal cannabis tweets from US jurisdictions with different legal statuses of cannabis from January to June 2021. METHODS: A total of 25,099 historical tweets from 51 US jurisdictions were collected using Python. Content analysis was performed on a random sample of tweets accounting for the population size of each US jurisdictions (n = 750). Results were presented separately by tweets posted from jurisdictions where all cannabis use (non-medicinal and medicinal) is 'fully legalised', 'illegal' and legal for 'medical-only' use. RESULTS: Four themes were identified: 'Policy', 'Therapeutic value', 'Sales and industry opportunities' and 'Adverse effects'. Most of the tweets were posted by the public. The most common theme was related to 'Policy' (32.5%-61.5% of the tweets). Tweets on 'Therapeutic value' were prevalent in all jurisdictions and accounted for 23.8%-32.1% of the tweets. Sales and promotional activities were prominent even in illegal jurisdictions (12.1%-26.5% of the tweets). Fewer than 10% of tweets were about intoxication and withdrawal symptoms. DISCUSSION AND CONCLUSION: This study has explored if content themes of medicinal cannabis tweets differed by cannabis legal status. Most tweets were pro-cannabis and they were related to policy, therapeutic value, and sales and industry opportunities. Tweets on unsubstantiated health claims, adverse effects and crime warrants continued surveillance as these conversations could allow us to estimate cannabis-related harms to inform health surveillance.

BACKGROUND: Skin pain in atopic dermatitis (AD) increases with disease severity and is associated with substantial quality of life (QoL) burden. OBJECTIVES: The aim of the study was to evaluate abrocitinib efficacy on skin pain and QoL in adults and adolescents with moderate-to-severe AD. METHODS: This post hoc analysis included data with abrocitinib administered as monotherapy (pooled phase 2b [NCT02780167] and phase 3 JADE MONO-1 [NCT03349060] and JADE MONO-2 [NCT03575871]) or in combination with topical therapy (phase 3 JADE COMPARE [NCT03720470] and JADE TEEN [NCT03796676]). Patients received oral, once-daily abrocitinib 200 mg, abrocitinib 100 mg, or placebo for 12 or 16 weeks (JADE COMPARE). Skin pain was rated using the Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD) skin pain Numerical Rating Scale (NRS) item ("How painful was your skin over the past 24 h?") on a scale from 0 (not painful) to 10 (extremely painful). Itch (Peak Pruritus NRS) and QoL (Dermatology Life Quality Index or Children's Dermatology Life Quality Index) were assessed. Least squares mean (LSM) change from baseline was analyzed using mixed-effects repeated measures modeling. RESULTS: A total of 1,822 patients (monotherapy pool, n = 942; JADE COMPARE, n = 595; and JADE TEEN, n = 285) were analyzed. LSM change from baseline in PSAAD skin pain score was significantly greater with abrocitinib versus placebo from week 2 through week 12 or 16 across all 3 study populations and occurred in a dose-dependent manner. A greater proportion of patients achieved a ≥4-point improvement from baseline in PSAAD skin pain score with abrocitinib (200 mg and 100 mg) versus placebo in the monotherapy pool (56% and 38% vs. 12%; week 12), JADE COMPARE (72% and 52% vs. 26%; week 16), and JADE TEEN (51% and 60% vs. 31%; week 12). Additionally, a greater proportion of patients achieved a stringent threshold of skin pain improvement (PSAAD skin pain score <2) with abrocitinib versus placebo. Adults and adolescents who achieved a ≥4-point improvement in skin pain reported greater QoL improvement than those who did not achieve a ≥4-point improvement. A positive correlation (≥0.3) was observed between skin pain and QoL and separately between skin pain and itch across the 3 study populations. CONCLUSION: Abrocitinib as monotherapy or in combination with topical therapy improved skin pain and was associated with improved QoL in both adults and adolescents with moderate-to-severe AD across all evaluated studies.

INTRODUCTION: Substance use, including drugs, alcohol and smoking have a significant health, social and economic impact. We aim to assess the rate and factors associated with treatment access among individuals with high-risk substance use. METHOD: This study is a cross-sectional analysis of the 2019 Australian National Drug Strategy Household Survey (N = 22,015). Participants were persons with high-risk substance use based on the Alcohol, Smoking and Substance Involvement Screening Test-Lite (ASSIST-Lite) and current smokers. We measured self-reports of past 12-month engagement in a tobacco, alcohol or other drugs treatment program. RESULTS: Overall, 0.4% had high-risk drug use (0.3% cannabis, 0.1% meth/amphetamine or 0.1% opioids), 7.4% had high-risk alcohol use, and 14.0% currently smoked. Among high-risk users, past 12-month treatment access rates were 50.6% [22.3-78.9%] for opioids, 27.1% [8.1-46.1%] for meth/amphetamine, 14.5% [4.3-24.7%] for cannabis, 9.6% [8.1-11.0%] for alcohol and 11.7% [10.6-12.9%] for current smoking. The primary source of treatment support was information and education (12.7% drugs, 4.6% alcohol, 4.0% smoking), followed by counselling (6.7% drugs, 4.5% alcohol, 3.0% smoking). Online or internet support was accessed by 5.9% (drug) and 1.6% (alcohol) people with high-risk use. Psychological distress was associated with treatment access (drugs: odds ratio 3.03 [0.77-11.95], p = 0.111; alcohol: odds ratio 3.16 [2.20-4.56], p ≤ 0.001; smoking: odds ratio 1.95 [1.52-2.49], p ≤ 0.001). DISCUSSION AND CONCLUSIONS: The proportion of people engaging in risky substance use who had used treatment programs remains low, especially for alcohol. Public health strategies to scale up treatment access are warranted.
