Bioinformatics Studies of Flavonoid Derivatives Compound from Saga Rambat Leaves as an Antipyretic Candidate

This research is backed by the frequent use of herbal plants in the community, one of which is the saga (Abrus precatory L.), which is used to reduce body temperature in the Tirtajaya District, Karawang Regency. Saga leaves contain several secondary metabolites with potential antipyretics, one of which is flavonoids. The study aimed to determine the inhibitory activity of flavonoid compounds of saga leaves as inhibitors of COX-2 receptors and IL-1 receptors that reduce fever. The methods used were pharmacokinetic and toxicity studies, molecular docking, and molecular dynamic simulation. The outcomes of molecular docking experiments with seven flavonoid-derived compounds from saga leaves targeting cyclooxygenase-2 (4PH9) receptors revealed that isohemiphloin compounds exhibited the most favorable Gibbs free energy (ΔG) at -7.08 kcal/mol. In the case of interleukin-1 (5R85), cirsimaritin compounds displayed the lowest Gibbs free energy (ΔG) at -7.78 kcal/mol. The analysis of drug screening results indicates that the best compound adheres to four of the five Lipinski rules. Furthermore, the predictions for pharmacokinetics and toxicity are fairly good, as the best compound demonstrates a favorable pharmacokinetic profile and is determined to be non-toxic. These findings collectively suggest that the isohemiphloin compound from saga leaves may be a promising candidate for developing an antipyretic drug, particularly due to its predicted interaction with the cyclooxygenase-2 (4PH9) receptor.

P833 Burden of steroid use in patients with moderate ulcerative colitis in Europe and the United States

Abstract Background Steroids are an effective short-term therapy option for induction of remission of ulcerative colitis (UC). However, long-term and frequent steroid use is common in clinical practice despite the risks of complications and adverse events.1 We aimed to describe disease burden in moderate UC patients (pts) based on their steroid use history. Methods Data were drawn from the Adelphi UC Disease Specific Programme™, a cross-sectional survey of gastroenterologists (GIs) and their pts in France, Germany, Italy, Spain, the UK and US from Jan 2020–Mar 2021. GIs reported patient demographics, clinical characteristics, treatments and healthcare resource utilization (HCRU). Pts reported quality of life (QoL) via the EQ-5D, short inflammatory bowel disease questionnaire (SIBDQ), and work productivity and activity impairment (WPAI) questionnaire. Pts had received 5-ASA or immunomodulator with no biologic or Janus kinase inhibitor in the 90 days following treatment initiation, had a history of physician-assessed moderate disease severity or a Mayo endoscopic subscore of 2, and no history of colectomy. Pts were categorized as: no steroids (NS; never received steroids), short term/intermittent (ST/I; currently receiving intermittent steroids or received steroids within the last two years for <90 days), or long term/escalated (LT/E; received steroids for ≥90 days within the last two years or had undergone steroid dose escalation within their current course). Analyses were descriptive. Results Overall, 217NS, 88 ST/I and 172 LT/E pts were analysed (Table 1). Median (interquartile range) total steroid use duration was 4.1 (1.6–22.3) months for ST/I and 14.9 (5.8–36.7) months for LT/E. NS (24.4%), ST/I (25.0%) and LT/E (26.2%) pts experienced abdominal pain; 0.5%, 4.6% and 5.2% had severe/extremely severe pain, respectively. Non-bloody diarrhoea was reported by 16.6%, 14.8%, 20.9% of pts, respectively. In the last 12 months, mean (standard deviation; SD) number of health care visits for NS, ST/I and LT/E was 6.1 (6.2), 7.3 (4.8), 8.0 (7.1); mean (SD) number of tests was 20.8 (17.2), 23.3 (15.7), 25.2 (18.2), respectively. NS, ST/I and LT/E patients reported mean EQ-5D scores (0.85, 0.81, 0.79), SIBDQ total scores (54.6, 49.7, 48.3) and overall work impairment (19.4, 23.1, 27.7). Key comorbidities experienced by ST/I and LT/E were hypertension, depression and diabetes (Figure 1). Conclusion Patients with long-term or escalated steroid use had high symptom burden, frequent comorbidities, high HCRU, and poor QoL. This highlights the need for alternative treatment approaches for moderate UC patients to avoid long-term steroid use. 1. Cross R.K. Inflamm Bowel Dis. 2017;23(10):1689–1701

Implications of the 988 suicide and crisis lifeline among college students experiencing substance use crises

AbstractSubstance use remains a significant concern across college campuses and is associated with adverse mental health outcomes. Low levels of student help‐seeking call for innovative forms of support that increase access to care. The new 988 Suicide and Crisis Lifeline has the potential to address this concern through free, 24/7 crisis support. Regression analyses concluded that more frequent substance use significantly predicted lower help‐seeking intentions for suicidal thoughts among a sample of 446 college students. Students were also least likely to use the lifeline for substance use concerns as opposed to other mental health concerns. Implications for counselors are provided.

Features of severe asthma response to anti-IL5/IL5r therapies: identikit of clinical remission.

Clinical remission (CliR) achievement has been recognized as a new potential outcome in severe asthma. Nevertheless, we still lack a detailed profile of what features could better identify patients undergoing clinical remission. In this study, we aim to address this issue, tracing a possible identikit of patients fulfilling remission criteria. We enrolled 266 patients with severe eosinophilic asthma (SEA) treated with a 12-month course of anti-IL5/IL5 receptor (IL5r) monoclonal antibodies. Patients with no exacerbation, OCS withdrawal, ACT ≥ 20 and FEV1 ≥ 80% after 1 year of biologic treatment were classified as in clinical remission. 30.5% of the enrolled patients achieved remission after biologic administration. CliR group showed a lower number of baseline asthma exacerbations and better lung function parameters, with a trend for higher ACT scores and a less frequent history of a positive skin prick test. CliR achievement was unlikely in presence of a higher BMI, a positive skin prick test, an increased number of asthma exacerbations before biologic treatment, anti-muscarinic administration, and a previous diagnosis of EGPA, bronchiectasis or osteoporosis. In contrast, a better lung function, an increased blood eosinophilic count, the presence of chronic rhinosinusitis with nasal polyps and a more frequent use of reliever therapy predicts remission development. Changes in exacerbations number, OCS use, ACT scores and FEV1% between remittent and non-remittent patients arise at specific follow up timepoints and are positively associated with CliR achievement. anti-IL5/IL5r biologics can induce CliR in a proportion of patients with SEA. Patients achieving remission demonstrate specific clinical, functional and inflammatory features, as well as a specific moment of improvement in all the CliR items.

Antiviral and Antibacterial 3D-Printed Products Functionalised with Poly(hexamethylene biguanide).

Infection prevention and public health are a vital concern worldwide, especially during pandemics such as COVID-19 and seasonal influenza. Frequent manual disinfection and use of chemical spray coatings at public facilities are the typical measures taken to protect people from coronaviruses and other pathogens. However, limitations of human resources and coating durability, as well as the safety of disinfectants used are the major concerns in society during a pandemic. Non-leachable antimicrobial agent poly(hexamethylene biguanide) (PHMB) was mixed into photocurable liquid resins to produce novel and tailor-made covers for public facilities via digital light processing, which is a popular 3D printing technique for satisfactory printing resolution. Potent efficacies of the 3D-printed plastics were achieved in standard antibacterial assessments against S. aureus, E. coli and K. pneumoniae. A total of 99.9% of Human coronavirus 229E was killed after being in contact with the 3D-printed samples (containing the promising PHMB formulation) for two hours. In an eight-week field test in Hong Kong Wetland Park, antibacterial performances of the specially designed 3D-printed covers analysed by environmental swabbing were also found to be satisfactory. With these remarkable outcomes, antimicrobial products prepared by digital light processing 3D printing can be regarded as a reliable solution to long-term infection prevention and control.

Learning design thinking well: organizing (introductory) workshops for optimal participant experience

A better understanding of the implementation of design thinking (DT) as a means to increase the assimilation of its practices is an important concern for R&D and innovation managers because more frequent use of DT practices raises organizational innovative capabilities. Introducing DT practices in workshops is a common, but also challenging approach to learning DT. Participants often have little to no prior encounters with the tools, techniques and principles used to practice DT and often mistrust or misinterpret the DT concept after a bad experience during the first exposure. For that reason, a suboptimal experience in introductory workshops can prevent or reduce the assimilation of DT practices. This study investigates how participant experience during first exposure as a vital precursor to the assimilation of DT practices can be improved via the organization of introductory workshops. We examine flow as the core experience measure in a quantitative‐inductive, quasi‐experimental study of two 3‐day DT workshops and compare periods with step‐by‐step acquisition of DT practices under guidance, periods of flexible, independent application of DT practices and periods of recovery. Our research employs a segmented time series analysis on more than 1100 real‐time observations collected with the experience sampling method (ESM). This study contributes to the scarce empirical research on improving the implementation of DT practices by indicating that a positive initial experience depends on workshop length, the logic of guided periods, the combination of guided and unguided periods, timing and type of recovery, as well as on team formation. Our results lead to five organizing principles, which can be used as testable propositions for future research, as well as in the planning and execution of (introductory) DT workshops.

Simplified segmental scleral buckling without localization and cryopexy: A retrospective comparison with conventional segmental scleral buckling

Abstract: PURPOSE: The aim of this study was to propose a simplified segmental scleral buckling (SSSB) technique that does not require break localization for less-experienced vitreoretinal surgeons. MATERIALS AND METHODS: This retrospective study compared the clinical results of 46 conventional and 23 SSSB (conventional segmental SB [CSSB] and SSSB, respectively) procedures in a tertiary referral retinal center in Taiwan between 2008 and 2019. In the CSSB group, breaks were localized during surgery. In the SSSB group, a wider sponge band and a longer scleral buckle were used to maximize the chances of sealing the retinal breaks based on the preoperative fundus examination findings and to minimize the positioning error caused by cyclotorsion, without performing indirect ophthalmoscopy. The primary outcome was assessed after 6 months. Patient characteristics, surgical parameters, and outcomes were compared between groups. The main outcomes were the duration of surgery, changes in visual acuity, primary success rate, rhegmatogenous retinal detachment recurrence rate, and the frequency of further laser photocoagulation. RESULTS: SSSB had a shorter duration than CSSB and was associated with more frequent use of longer and wider explants and need for further laser retinopexy. Both groups showed high primary success rates (95.65%). CONCLUSION: The primary success rates for the SSSB and CSSB groups were comparable and equally high. SSSB required laser retinopexy more frequently and was a shorter procedure.

On the meaning of intonational contours: a view from scalar inference

This paper investigates the meaning of intonational contours by experimentally testing how they affect the likelihood of scalar inference (SI) calculation. Our main test case is the rise-fall-rise contour (RFR) which, based on prior theoretical work, is predicted to either increase or decrease the likelihood of SI. We conducted two experiments using an inference task: one where participants first produce a target sentence with their choice of contour and one where participants listen to a pre-recorded target sentence with a particular contour. The experiments converged in showing that the RFR increases SI rate relative to a neutral fall. Additionally, production data revealed the frequent use of another contour that resembles the Contradiction Contour, which we label Concession Contour. This contour also led to an increase in SI rate, although to a lesser extent than the RFR. In addition to informing the theoretical literature on RFR, our results also highlight the methodological importance of controlling for intonation in the study of SI.

Asthma prevalence among US 9th-12th graders who report past 30-day cannabis use in 2019.

Little is known about the relationship between cannabis use and asthma among youth in the US. The aims of this study were to estimate prevalence of asthma among youth who reported any cannabis use in the past 30 days, relative to those who did not, and to investigate the relationship between frequency of cannabis use and prevalence of asthma, adjusting for demographic characteristics and cigarette use. Data were drawn from the 2019 Youth Risk Behavior Surveillance System (YRBSS), a CDC national high school survey, which collects data from students in grades 9-12 across the US bi-annually. Logistic regression was used to examine the prevalence of asthma among youth who reported any past 30-day cannabis use, relative to no use, and by frequency of cannabis use, adjusting for demographic characteristics and cigarette use. Asthma was more common among youth who reported any cannabis use, relative to youth who reported no use (29.07% vs. 23.62%; AOR = 1.25 (1.20, 1.30)). Asthma was greater among youth who reported more frequent cannabis use; asthma was highest among youth who reported having used cannabis "40 or more times" in the month (31.38%; AOR = 1.35 (1.25, 1.45)) CONCLUSION: Asthma is more common among youth who use cannabis, relative to those who do not, and the prevalence of asthma increases with frequency of use among 9th-12th graders in the US. More public health and clinical research is needed quickly to produce scientific data that can inform clinical guidelines and public health policy, as well as parents and youth, on the potential relationship between cannabis use and respiratory health among youth.

Cannabis Use Among Students in Grades 8, 10, and 12, by Sex - King County, Washington, 2008-2021.

Cannabis use during adolescence is associated with poor outcomes, including cognitive impairment, cannabis use disorder, and impaired driving. To guide prevention and use reduction strategies, Public Health - Seattle & King County described recent trends in cannabis use by sex among King County, Washington students in grades 8, 10, and 12 and examined trends in sex-based differences. Data collected during seven 2008-2021 survey periods by the Healthy Youth Survey (administered by the Washington State Department of Health) and restricted to King County students in grades 8, 10, and 12 (range=33,439-39,391 students per cycle) were analyzed. Prevalence estimates were generated and sex-based prevalence differences (PDs) in current use (≥1 day during the previous 30 days) and frequent use (≥6 days during the previous 30 days) were assessed. PD models used weighted generalized linear regression with an interaction between sex and survey year. During 2008-2021, cannabis use declined among both male and female students. During 2008-2014, cannabis use was higher among male students than among female students (e.g., PD in 2008=4.8%) and not significantly different during 2014-2016; however, in 2021, current-use prevalence was lower among male students than among female students for the first time (PD=-1.3%). Frequent-use prevalence was similar among males and females. By grade levels, the highest prevalence of both current and frequent cannabis use was observed among 12th grade students, followed by 10th and 8th graders. Sex-specific differences by grade mirrored overall patterns. Developing tailored interventions that consider potential differences in risk and protective factors by sex or gender identity could promote equity in youth (grades 8, 10, and 12) cannabis use reduction measures.

Determination of dichlorvos pesticide residues in the groundwater of the environment surrounding Al‐Sin Lake using a high‐performance liquid chromatography

AbstractThe unreasonable use of agrochemicals and various human activities in the environment of Al‐Sin Lake basin may cause pollution to water, especially with widely used organophosphate pesticides, which have an effect on the human nervous system. This research sought to determine concentrations of dichlorvos of the synthetic organophosphate pesticide in the waters of the environment surrounding Al‐Sin Lake in the Syrian coastal area. A questionnaire form was dispensed to the local residents in the region, to determine the status of the studied area. Ground and surface water samples were collected from several locations surrounding the Lake. The first site is surrounded by greenhouses and a citrus orchard. The second is the Surit spring. The third site includes greenhouses. The fourth site represents surface water (Lake Surit). The study lasted for seven consecutive months from December until June 2020–2021, samples were taken once a month. Various parameters (pH, EC, TDS, and PO4−3) were measured. Dichlorvos was extracted from the samples using solvents (hexane‐acetone) to be ready for analysis using high‐performance liquid chromatography. The results showed the presence of dichlorvos residues in the studied water samples, with average concentrations ranging between 0.2 and 1.3 µg.L−1, which were higher than the recommended value for individual pesticide in water (0.1 µg.L−1) as recommended by the European Union. Observations of dichlorvos concentration indicated some increase at lower pH. Consequently, contamination of ground and surface waters with dichlorvos was observed in the studied sites, because of its frequent use and its high solubility in water. This unregulated use of dichlorvos can pose a matter of public health concern.

The Impact of Social Media Use on Mental Health and Family Functioning Within Web-Based Communities in Saudi Arabia: Ethnographic Correlational Study.

In recent years, increasing numbers of parents, activists, and decision-makers have raised concerns about the potential adverse effects of social media use on both mental health and family functioning. Although some studies have indicated associations between social media use and negative mental health outcomes, others have found no evidence of mental health harm. This correlation study investigated the interplay between social media use, mental health, and family functioning. Analyzing data from 314 users, this study explores diverse mental health outcomes. The study places particular emphasis on the Saudi Arabian sample, providing valuable insights into the cultural context and shedding light on the specific dynamics of social media's impact on mental well-being and family dynamics in this demographic context. We collected data through a subsection of an anonymous web-based survey titled "The Effect of COVID-19 on Social Media Usage, Mental Health, and Family Functioning." The survey was distributed through diverse web-based platforms in Saudi Arabia, emphasizing the Saudi sample. The participants indicated their social media accounts and estimated their daily use. Mental health was assessed using the General Health Questionnaire and family functioning was evaluated using the Family Assessment Device Questionnaire. In addition, 6 mental health conditions (anxiety, self-esteem, depression, body dysmorphia, social media addiction, and eating disorders) were self-reported by participants. The study demonstrates a pattern of frequent social media use, with a significant portion dedicating 3-5 hours daily for web-based activities, and most of the sample accessed platforms multiple times a day. Despite concerns about social media addiction and perceived unhealthiness, participants cited staying connected with friends and family as their primary motivation for social media use. WhatsApp was perceived as the most positively impactful, whereas TikTok was considered the most negative for our Saudi sample. YouTube, Instagram, and Snapchat users reported poorer mental health compared with nonusers of these platforms. Mental health effects encompassed anxiety and addiction, with age and gender emerging as significant factors. Associations between social media use and family functioning were evident, with higher social media quartiles correlating with a greater likelihood of mental health and unhealthy family functioning. Logistic regression identified age and gender as factors linked to affected mental health, particularly noting that female participants aged 25-34 years were found to be more susceptible to affected mental health. In addition, multivariable analysis identified age and social media use quartiles as factors associated with poor family functioning. This study examined how social media affects mental health and family functioning in Saudi Arabia. These findings underscore the need for culturally tailored interventions to address these challenges, considering diverse demographic needs. Recognizing these nuances can guide the development of interventions to promote digital well-being, acknowledging the importance of familial connections in Saudi society.

Does frequent internet use increase the propensity to change address? UK evidence from Understanding Society on mobility preferences, expectations and moves

AbstractLong‐term declines in rates of internal migration have been widely documented in many developed economies. Accompanying this decline has been a proliferation in the everyday use of new technologies such as the internet. New communication technologies have been theorised to influence migration decisions, but the direction of this influence is ambiguous, with some studies finding that they decrease migration, others that they increase it. Using data from the UK Household Longitudinal Study, this paper assesses the relationship between internet use and preferences/expectations to change address as well as the decision to move. Although frequent users of the internet tend to be more mobile on average, longitudinal analysis offers no evidence that internet use influences migratory preferences and expectations or actual moves. This paper contributes to the literature by studying a developed country with high levels of internet penetration, by engaging not only with actual moves but also with preferences and expectations to move, and by drawing on longitudinal data to address unmeasured confounding in so far as possible. More broadly, it provides a reference point for future studies which might consider whether internet use plays a different role in the aftermath of the COVID‐19 pandemic.

Conversation-based hybrid UI for the repertory grid technique: A lab experiment into automation of qualitative surveys

A frequent use of conversational user interfaces (CUIs) today is improving the users’ experience with online quantitative surveys. In this paper, we explore the use of CUIs in qualitative surveys. As a concrete use case, we adopt a specific, well-structured, qualitative research method called the repertory grid technique (RGT). We developed a hybrid user interface (HUI) that combines a graphical user interface (GUI) with a CUI to automate the distinct stages in a RGT survey. A pilot study was used to verify the feasibility of the approach and to fine-tune interface aspects of an initial prototype. In this paper, we report the results of a within-subject lab experiment with 24 participants that aimed to establish the performance and UX in a realistic context of a more advanced prototype. We observed a small decrease in UX in some hedonistic aspects, but also confirmed that the HUI performs similarly to a human agent in most pragmatic aspects. These results provide support for our hypothesis that automating qualitative surveys is possible with proper interface design. We hope that our work can inspire other researchers to design additional tools for qualitative survey automation, especially now that generative AI systems, such as ChatGPT, open up interesting new ways for computer systems to interact with users in natural language.

Weekly hair washing: The recommended solution for women with afro-textured hair to alleviate dandruff and scalp discomfort.

Dandruff and scalp discomfort are common concerns for women and men in Africa. Moreover, women with afro-textured hair are prone to scalp discomfort owing to irregular hair washing, frequent use of oil-based products on their scalp, and harsh chemical treatments. Current literature does not, however, provide data on the pathophysiological mechanisms of these conditions in this population. In this study, we investigated the mechanisms behind scalp discomfort and dandruff in women of African descent before and after hair washing. We conducted the in Durban, South Africa, over a 3-week period with 60 women of African descent aged 20-40 years. The respondents were equally divided into a "dandruff" and a "no dandruff" group, based on clinical grading of adherent dandruff by a dermatologist. Malassezia spp. and bacterial loads were quantified by quantitative polymerase chain reaction. Evaluations of scalp condition and sample collection were performed at five time points during the 3 weeks. Data on discomfort symptoms were collected via a self-assessment questionnaire. We observed that the dandruff severity peaked at the end of the first week after hair washing and plateaued from thereon in both groups. Dandruff was associated with higher Malassezia and bacterial load counts and there was a direct correlation between the Malassezia spp. load and dandruff score. Via self-assessment questionnaire responses submitted by participants, we observed that itching was the most pronounced scalp discomfort, compared with the sensation of tingling and burning at baseline, while an improvement of the scalp symptoms of dandruff and itch was observed in both groups after one hair wash. The study also showed that higher colonization with Malassezia spp. and bacteria is associated with dandruff independently of the time point, confirming a scalp microbiome contribution to the dandruff pathophysiology in the study population. The benefits of washing were, however, not sustained after 1 week and we thus recommend weekly hair washing for long-term management of dandruff and scalp itchiness in this population.

Assessing transnational spillover effects of Mexico's front-of-package nutritional labeling system among Mexican Americans in the US

ObjectiveIn 2020, Mexico implemented innovative front-of-package nutrition warning labels (FoPWLs) for packaged foods to increase the salience and understanding of nutrition information. This study evaluated Mexican Americans' self-reported exposure to Mexican FoPWLs and self-reported effects of FoPWLs on purchasing behavior. MethodsThe 2021 International Food Policy Study surveyed online panels of adult Mexican Americans in the US (n = 3361) to self-report on buying food at Mexican-oriented stores, noticing Mexican FoPWLs, and being influenced by FoPWLs to purchase less of eight different unhealthy foods (each assessed separately). After recoding the frequency of buying foods in Mexican stores and noticing FoPWLs (i.e., “often” or “very often” vs. less often), logistic models regressed these outcomes on sociodemographics, adjusting for post-stratification weights. ResultsMost participants (88.0%) purchased foods in Mexican stores. Of these, 64.1% reported noticing FoPWLs, among whom many reported that FoPWLs influenced them to buy fewer unhealthy foods (range = 32% [snacks like chips] - 44% [colas]). Participants were more likely to buy foods in Mexican stores and notice FoPWLs if they were younger, had ≥two children at home vs no children (AOR = 1.40, 95%CI = 1.15–1.71; AOR = 1.37, 95%CI = 1.03–1.80, respectively), and more frequently used Spanish (AOR = 1.91, 95%CI = 1.77–2.07; AOR = 1.87, 95%CI = 1.69–2.07). Also, high vs. low education (AOR = 1.51, 95%CI = 1.17–1.94) and higher income adequacy (AOR = 1.37, 95%CI = 1.25–1.51) were positively associated with noticing FoPWLs. Being female and more frequent Spanish use were consistently associated with reporting purchase of fewer unhealthy foods because of FoPWLs. ConclusionsMany Mexican Americans report both exposure to Mexican FOPWLs and reducing purchases of unhealthy foods because of them.

Mortality risk and causes of death among people who use opioids in a take-home naloxone cohort

BackgroundPeople who use opioids (PWUO) have an excess mortality from a range of causes. The cumulative effect of behavioral, social, and health risk factors complicates the interpretation of the effects of suitable interventions. This study explores mortality causes among a cohort of PWUO in the take-home naloxone (THN) program. MethodsThis was a prospective cohort study of PWUO who received THN between 2015 and 2023. Participant data was linked with death registry data. Crude mortality rates and standardized mortality ratios (SMRs) were calculated for all causes, internal causes, and accidental opioid overdoses (AOOs). In addition to age and gender, risk factors like main route of administration, polydrug use, self-experienced overdoses, and using while alone were fitted in a Cox Regression model to explore factors associated with mortality. ResultsThe 2194 participants had a considerably higher mortality ratio for all causes investigated when compared to the general population (SMR=10.9, 95 % CI = 9.3,12.6). AOOs were the most prevalent cause of death (49 %). Those who reported frequent opioid use while alone had an elevated risk of dying of 2.6 (95 % CI = 1.1,6.4) compared to those who never used while alone. ConclusionsFrequent opioid use while alone was associated with elevated mortality risk, supporting the importance of overdose prevention education with naloxone distribution, and additional efforts to improve environmental and social areas for safer drug-use practices among PWUO. The variety of mortality causes found in this study illustrates the need for multifaceted and targeted interventions for people at risk of overdosing.

Design, synthesis, antifungal activity and molecular docking of novel pyrazole-4-carboxamides containing tertiary alcohol and difluoromethyl moiety as potential succinate dehydrogenase inhibitors.

Resistance problems with the long-term and frequent use of existing fungicides, and the lack of structure diversity of traditional pyrazole-4-carboxamide succinate dehydrogenase inhibitors, it is highly required to design and develop new fungicides to address the resistance issue. Different from previous pyrazole-4-carboxamide succinate dehydrogenase inhibitors by breaking the norm of difluoromethyl at the C-3 position of pyrazole and introducing a tertiary alcohol group at the C-3 position, 27 novel pyrazole-4-carboxamide derivatives were designed, synthesized and characterized by proton (1 H) nuclear magnetic resonance (NMR), carbon-13 (13 C) NMR, fluorine-19 (19 F) NMR and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS). The crystal structures of compounds A14 and C5 were analyzed by single crystal X-ray diffraction. Their in vitro antifungal activities were evaluated against phytopathogen Fusarium graminearum, Botrytis cinerea, Phytophthora capsica, Sclerotinia sclerotiorum, Thanatephorus cucumeris. The results displayed that most of them exhibited significant antifungal activities against S. sclerotiorum at 50 mg/L, the half maximal effective concentration (EC50 ) data of A8 and A14 were 3.96 and 2.52 mg/L, respectively. Their in vivo antifungal activities were evaluated against Pseudoperonospora cubensis, Puccinia sorghi Schw, Colletotrichum gloeosporioides, F. graminearum, Erysiphe graminis, Thanatephorus cucumeris, the control efficacies of A6, B3, C3, and C6 against E. graminis reached 100% at a concentration of 400 mg/L. The molecular docking results showed that the binding mode of the target compounds containing tertiary alcohols were similar to that of fluxapyroxad in succinate dehydrogenase. In addition, tertiary alcohols were involved in the formation of hydrogen bonds. The excellent in vitro and in vivo inhibitory activities of novel pyrazole-4-carboxamide derivatives against succinate dehydrogenase were reported for the first time, and they could be used as the potential lead compounds. © 2023 Society of Chemical Industry.

Do parent media habits contribute to child global development?

Parents of preschoolers' report using screen media frequently. More frequent screen use by parents may undermine child development by displacing time for foundational parent-child interactions. The objective of the present study is to examine the extent to which parent screen use contributes to child global development 1 year later. Data are from a cohort of 315 preschoolers from Nova Scotia, Canada and their parents during the COVID-19 pandemic. Parents reported the number of hours per day they spent using screens, as well as child screen time and sex, and parent educational attainment. Our outcome is child global development scores, which combine assessments of communication, cognitive, personal-social, and motor skills measured at 4.5 using the Ages and Stages Questionnaire (ASQ) (N = 249, 79% retained). Parents in our sample spent on average 6.35 h per day using screen media outside of work (SD = 3.07) and children spent on average 3.43 h per/day using screens. Multivariate linear regression indicated that each 1-h increase in parents daily screen media use, corresponded to a 1.25 decrease in child global development scores, B = -1.25 p < 0.05, 95% CI between -2.37 and -0.13. Our results indicate that parent screen use may represent a key component of children's media ecology. Given the importance of global development in early childhood for later health and achievement, the present results suggest that interventions should include parent screen use habits in media wellness interventions.
