Bridging the Telehealth Digital Divide With Collegiate Navigators: Mixed Methods Evaluation Study of a Service-Learning Health Disparities Course.

BACKGROUND: Limited digital literacy is a barrier for vulnerable patients accessing health care. OBJECTIVE: The Stanford Technology Access Resource Team (START), a service-learning course created to bridge the telehealth digital divide, trained undergraduate and graduate students to provide hands-on patient support to improve access to electronic medical records (EMRs) and video visits while learning about social determinants of health. METHODS: START students reached out to 1185 patients (n=711, 60% from primary care clinics of a large academic medical center and n=474, 40% from a federally qualified health center). Registries consisted of patients without an EMR account (at primary care clinics) or patients with a scheduled telehealth visit (at a federally qualified health center). Patient outcomes were evaluated by successful EMR enrollments and video visit setups. Student outcomes were assessed by reflections coded for thematic content. RESULTS: Over 6 academic quarters, 57 students reached out to 1185 registry patients. Of the 229 patients contacted, 141 desired technical support. START students successfully established EMR accounts and set up video visits for 78.7% (111/141) of patients. After program completion, we reached out to 13.5% (19/141) of patients to collect perspectives on program utility. The majority (18/19, 94.7%) reported that START students were helpful, and 73.7% (14/19) reported that they had successfully connected with their health care provider in a digital visit. Inability to establish access included a lack of Wi-Fi or device access, the absence of an interpreter, and a disability that precluded the use of video visits. Qualitative analysis of student reflections showed an impact on future career goals and improved awareness of health disparities of technology access. CONCLUSIONS: Of the patients who desired telehealth access, START improved access for 78.7% (111/141) of patients. Students found that START broadened their understanding of health disparities and social determinants of health and influenced their future career goals.

What is the relationship between risk attitudes and ambient temperature? Evidence from a large population-based cohort study.

Rising temperatures affect human behavior and risk-taking in several domains. However, it is not yet well understood just how ambient temperature shapes risk attitudes. Using data from the large population-based KORA-Fit study (Cooperative Health Research in the Region of Augsburg) of older people (N=2454), we identify a statistically significant, but very small, positive association between short-term ambient temperature changes and individuals' general willingness to take risks. Health-related risk attitudes, however, show no significant relationship with temperature. These findings support a domain-specific view of risk attitudes, with results remaining consistent for vulnerable individuals with the chronic conditions diabetes, hypertension, and asthma. Overall, our findings suggest that risk attitudes are somewhat stable towards changes in ambient temperature.

Contraception used by people assigned female at birth with spinal cord injury.

OBJECTIVE: There is limited data on contraception used by people assigned female at birth with spinal cord injury (SCI). Pregnancy in people with SCI can be medically complex, therefore access to contraception to prevent unplanned pregnancies is imperative. This study aimed to assess the availability of contraception from health care providers (HCPs) to people with SCI and contraception methods used. METHODS: An online international questionnaire was distributed. Demographic data and reproductive histories were recorded. 780 responses were received from participants in 33 different countries. Most participants lived in North America and self-identified as white. 75% had a traumatic SCI. Most SCIs were at cervical and thoracic levels and ASIA-A and ASIA-B. Descriptive and chi square statistics were used. RESULTS: The recruitment rate was 85.4% and completion rate was 73.8%. 93.6% of participants reported ever having been sexually active, while 60.7% reported sexual activity over the past year. Of people who were injured under the age of 50 and who have been sexually active, 63.6% were offered birth control by a HCP. Condoms were used by 44.5% of participants, withdrawal by 20.1%, the combined oral contraceptive pill by 28.4% and intra-uterine device by 20.1% of respondents. CONCLUSIONS: This is the largest known study on SCI and contraception. Most people with SCI are sexually active. The withdrawal method and no contraception are used by many individuals, which may increase the risk of unplanned pregnancy. Increased use of highly effective contraception in this population may be achieved through HCP-initiated conversations about sexual health. OBJECTIF: Les données sont limitées en ce qui concerne la contraception utilisée par les personnes de sexe féminin assigné à la naissance atteinte de lésions médullaires (LM). La prise en charge de la grossesse en contexte de LM peut s'avérer complexe; il est donc primordial que les personnes atteintes aient accès à la contraception pour éviter une grossesse non planifiée. Cette étude visait à évaluer l'offre contraceptive des prestataires de soins et les méthodes contraceptives utilisées chez les personnes atteintes d'une LM. MéTHODES: Un questionnaire en ligne a été distribué à des personnes de partout dans le monde. Les données démographiques et les antécédents reproductifs ont été recueillis. Au total, 780 réponses de participantes provenant de 33 pays ont été reçues. La plupart vivaient en Amérique du Nord et s'identifiaient comme Blanches. De ces participantes, 75 % ont indiqué avoir une LM traumatique. Les LM étaient généralement cervicaux ou thoraciques et de grades A ou B sur l'échelle de l'ASIA. L'analyse des données repose sur les statistiques descriptives et le test du chi carré. RéSULTATS: Le taux de recrutement s'élevait à 85,4 % et le taux de questionnaires remplis à 73,8 %. Parmi les participantes, 93,6 % ont déclaré avoir déjà été sexuellement actives et 60,7 % ont déclaré avoir eu des activités sexuelles dans la dernière année. Chez les personnes sexuellement actives ayant contracté une LM avant 50 ans, 63,6 % se sont fait offrir un contraceptif par un prestataire de soins. Dans l'ensemble, 44,5 % des participantes ont utilisé le condom; 20,1 %, la méthode du retrait; 28,4 %, la contraception orale combinée; et 20,1 %, le dispositif intra-utérin. CONCLUSIONS: Cette étude sur les LM et la contraception est la plus vaste à ce jour. La plupart des personnes atteintes d'une LM sont sexuellement actives. Bon nombre d'entre elles utilisent la méthode du retrait ou n'utilisent aucune méthode contraceptive; des facteurs qui peuvent augmenter le risque de grossesse non planifiée. Il serait sans doute possible d'augmenter l'utilisation de méthodes contraceptives hautement efficaces dans cette population au moyen de conversations sur la santé sexuelle amorcées par le prestataire de soins.

The Influence of Childhood Emotional Abuse and Neglect on Love Addiction: The Indirect Effect of Vulnerable Narcissism Among Female and Male Emerging Adults.

Childhood maltreatment is a key precursor to vulnerable narcissism since it likely lead to a narcissistic injury that triggers defenses against rage and abandonment. In later life, this pattern may contribute to a maladaptive model of love relationships. The present study explored the association between different types of childhood maltreatment (i.e., emotional, physical, and sexual abuse; physical and emotional neglect) and love addiction via vulnerable narcissism in a community sample of 505 cisgender emerging adults (M = 24.90, SD = 2.67; 76.6% assigned female at birth (AFAB); 68.5% heterosexual) residing in Italy. Data collection relied on self-report questionnaires administered online through the Qualtrics platform, and study hypotheses were tested using structural equation modeling. The results showed that childhood emotional abuse and emotional neglect directly influenced love addiction, while physical and sexual abuse, as well as physical neglect, showed no significant effects. Greater childhood emotional abuse and neglect were associated with increased vulnerable narcissism, leading to higher levels of love addiction. Gender differences emerged, with the indirect effect of vulnerable narcissism on the relationship between emotional neglect and love addiction significant only for AFAB. The findings emphasize the risk of love addiction in emerging adults with a history of childhood emotional abuse and neglect, highlighting the importance of addressing childhood emotional maltreatment and vulnerable narcissistic personality traits in interventions to treat this condition.

Support for Siblings of Children With Complex Care Needs: Public Health Nurses' Perceptions of Their Role in Primary Schools.

AIM: To explore the role of public health nurses (PHNs) in Norwegian primary school health services in supporting siblings who have a brother or a sister with complex care needs. DESIGN: A qualitative, exploratory design using focus groups combined with visual methods. METHODS: Nineteen Norwegian PHNs participated in three focus group discussions between May and September 2022. The nurses were asked to draw themselves as PHNs working in primary schools. Braun and Clarke's reflexive thematic approach was used to analyse the transcribed interviews. The drawings were analysed using critical visual analysis methodology. RESULTS: The findings revealed that PHNs in primary schools focused on establishing good relationships and found it important to be flexible and creative. However, a challenge to successful service provision in supporting siblings and their families was that the nurses lacked support for the implementation of health promotion interventions and often felt alone. The analysis elicited three main themes: 'the importance of relationships and flexibility in meeting siblings' needs', 'feeling alone with responsibility for supporting siblings' and 'the forgotten children: a need for coordinated services'. CONCLUSION: PHNs in school health services are in a unique position to provide support to improve siblings' mental health and well-being. To fully benefit from PHNs' potential to support siblings, there is a need to clarify guidelines and develop evidence-based interventions. IMPACT: This study provides valuable insights for health authorities, educators and practitioners on what inhibits sibling support in Norway. The study highlights the potential for PHNs to play a significant role in delivering timely health-promoting interventions for these siblings in school settings independent of context. REPORTING METHOD: This study was reported in accordance with the Consolidated Criteria for Reporting Qualitative Research (COREQ). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Characterization of pesticide exposures and their associations with asthma morbidity in a predominantly low-income urban pediatric cohort in Baltimore City.

BACKGROUND: Pesticides may impact respiratory health, yet evidence of their impact on pediatric asthma morbidity is limited, particularly among urban children. OBJECTIVE: To characterize pesticide biomarker concentrations and evaluate their associations with pediatric asthma morbidity among predominantly low-income, Black children in Baltimore City, USA. METHODS: We measured urinary concentrations of 10 biomarkers for pyrethroid insecticides (cyfluthrin:4F-3PBA, permethrin:3PBA), organophosphate insecticides (chlorpyrifos:TCPY, malathion:MDA, parathion:PNP, diazinon:IMPY), and herbicides (glyphosate:AMPA, GPS; 2,4-dicholorphenoxyacetic acid:2,4-D; 2,4,5-tricholorphenoxyacetic acid:2,4,5-T) among 148 children (5-17 years) with established asthma. Urine samples and asthma morbidity measures (asthma symptoms, healthcare utilization, lung function and inflammation) were collected every three months for a year. Generalized estimating equations were used to examine associations between pesticide biomarker concentrations and asthma morbidity measures, controlling for age, sex, race, caregiver education, season, and environmental tobacco smoke. In sensitivity analyses, we assessed the robustness of our results after accounting for environmental co-exposures. RESULTS: Frequently detected (≥90% detection) pesticide biomarker concentrations (IMPY, 3PBA, PNP, TCPY, AMPA, GPS) varied considerably within children over the follow-up period (intraclass correlation coefficients: 0.1-0.2). Consistent positive significant associations were observed between the chlorpyrifos biomarker, TCPY, and asthma symptoms. Urinary concentrations of TCPY were associated with increased odds of coughing, wheezing, or chest tightness (adjusted Odds Ratio, aOR, TCPY:1.60, 95% Confidence Interval, CI:1.17-2.18). Urinary concentrations of TCPY were also associated with maximal symptom days (aOR:1.38, CI:1.02-1.86), exercise-related symptoms (aOR:1.63, CI:1.09-2.44), and hospitalizations for asthma (aOR:2.84, CI:1.08-7.43). We did not observe consistent evidence of associations between the pesticide exposures assessed and lung function or inflammation measures. CONCLUSION: Among predominantly Black children with asthma, we found evidence that chlorpyrifos is associated with asthma morbidity. Further research is needed to assess the contribution of pesticide exposures to pediatric respiratory health and characterize exposure sources among vulnerable populations to inform targeted interventions against potentially harmful pesticide exposures.

How Do Persons With Disabilities and/or Complex Health Conditions Perceive Oral Health? A Qualitative Study.

OBJECTIVES: This qualitative study aimed to explore the experience and perception of the mouth, oral health, functioning and the social environment amongst adults with disabilities and complex health conditions. METHODS: Purposive sampling using the maximum variation strategy was performed to select participants with a wide range of experiences in terms of demographics, disability and health conditions. Consent was sought, and semi-structured interviews were conducted, recorded and transcribed verbatim. Within the interpretivist tradition, a phenomenological approach was used to describe the lived, contextualised experience of people in relation to their mouths, as described by participants. Thematic analysis was undertaken. RESULTS: Eighteen participants with disabilities and complex health conditions were interviewed. Twelve individuals had an intellectual disability. Three main themes were identified: perception of the mouth and oral health; symptomatic perceptions and responses to oral health problems; and inter-relationships between the mouth, oral health and the socio-medical environment. The mouth had a central place in the lives of the participants, but its importance was only recognised when oral health problems interfered with daily life, function, social relationships, family life or autonomy. Certain social determinants of health were identified: social exclusion, financial insecurity, lack of autonomy, nutrition and negotiation of services. Oral problems were perceived as an additional burden to those with disabilities or complex health conditions. CONCLUSION: This study provided insight into the daily lives of adults with disabilities and complex health conditions. It helps to fill the gaps in the existing literature regarding the perceptions of the mouth and oral health, connecting oral function, general health and social environment for this population. TRIAL REGISTRATION: This study was registered into ClinicalTrials.gov (NCT04815434).

The Population Typology of Conspiracy Beliefs About Sars-Cov-2 Origin in Russia Based on Predictive Modelling of COMET-G Study Data: Incoherent Attitude Indicator as a Predisposing Factor for Developing Mental Disturbances.

BACKGROUND: We examined the prevalence and spread of conspiracy beliefs about the origins of the COVID-19 pandemic among representatives of the Russian population. Our study aimed to identify belief clusters and develop predictive models to understand the factors that influence conspiracy beliefs, particularly in the context of how they might evolve in response to socio-political events and cause mental disturbances, thus in relation to specific pathways of the infodemic and psychodemic waves that spread among vulnerable population groups. METHODS: Data respondents to the international COMET-G study living in Russia during pandemic period (n=7,777) were analyzed using descriptive statistics, K-means clustering, and various machine learning models, including gradient boosting. We identified distinct populations depending on predominant beliefs about COVID-19 pandemic origins, and applied game theory (Shapely additive explanations) to determine the most influential variables in predicting cluster membership. RESULTS: Four distinct belief clusters emerged, which we designate as Naturalists, Conspiracists, COVID-Sceptics, and the Incoherent Attitude groups. The Incoherent Attitude cluster constituted 20.8% of the sample, and was particularly associated with mental health signs such as sleep disturbances and the use of psychotropic medications. Internet use and mental health-related factors, as well as the respondents' education level, were key predictors of mental disturbances with mediating effects of the conspiracy views across all clusters. Conspiracy beliefs about COVID-19 origin were highly fluid/variable, often being shaped by external sociopolitical factors rather than objective health data. CONCLUSIONS: The cluster with Incoherent Attitude regarding COVID-pandemic origins, which had an association with psychoticism, showed a greater predisposition for mental health problems, than did the Conspiracist, Naturalist and Sceptic clusters. We suppose that underlying psychoticism bears a relation to their sleep problems and resorting to use of psychotropic medications. These results emphasizes the global health need for implementing target-focused and selective strategies that address public misinformation and promote the adoption of critical thinking skills to mitigate the impact of conspiracy theories, considering the factors of education level and pre-existing mental disorders.

Symptomatic Nonstenotic Carotids: A Topical Review.

Historically, the management of carotid artery disease has primarily focused on the degree of stenosis as the main indicator for assessing stroke etiology, risk, and need for intervention. However, accumulating evidence suggests that structural and biological features within the arterial wall, such as intraplaque hemorrhage, may have superior diagnostic, prognostic, and therapeutic values. Under current guidelines, unless an atheroma results in ≥50% stenosis, it is not considered the cause of a cerebrovascular event. This results in extensive and often unproductive diagnostic workup, prescription of ineffective medical therapy, and preclusion of patients from receiving revascularization procedures that have been shown to prevent recurrent cerebrovascular events in cases of ≥50% stenosis. A subset of embolic strokes of undetermined source, which account for up to 25% of all ischemic cerebrovascular events, are thought to be due to thromboembolic phenomena from undiagnosed plaque disruptions in nonstenotic arteries (<50% stenosis). Recently, it has been proposed to reclassify this subgroup of patients as symptomatic nonstenotic carotid if the carotid plaque ipsilateral to the cerebrovascular event presents with high-risk features including intraplaque hemorrhage, lipid-rich necrotic core, thinning/rupture of the fibrous cap, and ulceration. In this review, we first provide a historical overview of the chain of events and circumstances that resulted in the present management of carotid artery disease. Second, we embed the contemporary biomarkers of plaque vulnerability in a modern mechanistic paradigm of carotid plaque disruption and thromboembolization. Third, we review the clinically available imaging tools to detect these biomarkers, and how their use has started to shed light on the prevalence and natural history of this underdiagnosed condition. Fourth, we review recent clinical studies employing a contemporary definition of symptomatic nonstenotic carotid and discuss targeted treatments for this condition. Finally, we make a case to generate the much-needed high-level evidence to align the clinical management of patients with symptomatic nonstenotic carotid with a contemporary understanding of plaque disruption and thromboembolization.

Racial Disparities in Anesthesia Care: A Systematic Review of Pain Management and Patient Outcomes.

Racial disparities in healthcare are a prominent issue that needs to be addressed to improve the quality of care for all patients. There are several disparities and biases related to the perceived pain tolerance people of color (POC) patients have and their need for analgesics. These biases lead to inadequate pain management and decreased health outcomes. Our study aims to highlight these disparities and how they impact the care patients receive, specifically in the field of anesthesia. To conduct this study, a comprehensive systematic literature search was performed, articles were included and removed according to specific inclusion and exclusion criteria, and a systematic review was performed. Sixteen papers that met the inclusion and exclusion criteria were selected, and after data collection, correlations between POC and pain tolerance were assessed throughout the articles. The studies reviewed showed that there may be some correlation between racial background and perceived pain tolerance. While some studies found that racial disparities may negatively impact the care POC patients receive, others found that there was no correlation at all. Regardless, more studies need to be conducted to assess the factors influencing the treatment of POC in anesthesia.

The current situation of health equity in underserved areas of Afghanistan.

Background: In Afghanistan, providing universal health coverage (UHC) in accordance with the principles of the UHC declaration is challenging on two fronts: the geographic topography of the country and the prevailing gender dynamics within the local culture. Methods: We conducted a desk review of underserved areas in the context of health services by gathering and analyzing existing literature, reports, and data using a combination of keywords and phrases such as: "underserved areas," "healthcare disparities," "access to healthcare," and "health services." The primary data were derived from an analysis of underserved populations conducted by the World Health Organization (WHO) Afghanistan's Emergency Program, supplemented by information from in-country partners. In addition to other reports, this review focused on analyzing the geographical availability of primary healthcare (PHC) services by employing the guidelines set forth in the SPHERE framework. It also took into account the social dynamics within the Afghan population that may create barriers to equity in terms of demand and access to PHC services. Results: Although there are a significant number of primary healthcare facilities in operation (4,242), they are unevenly distributed across different regions of Afghanistan, resulting in almost 25% of the population being underserved. The underserved population is nearly equally distributed between genders, with the majority residing in rural communities. Women of childbearing age represent 28% of the underserved population. Children under the age of five represent 16-18% of the underserved population in all regions, except in the western region, where they represent between 12 and 13%. Individuals over 60 years of age represent 1-3% of the underserved population across all regions. More than 50% of the population in the Central Highlands of Afghanistan is underserved, followed by the western and southern regions. Ghor province in the western region has the highest proportion of underserved populations, followed by Zabul province in the southern region. Conclusion: Afghanistan is currently experiencing a protracted humanitarian crisis, with millions of people living in poverty and lacking access to healthcare. This situation exposes them to serious risks such as disease epidemics, starvation, and maternal and child mortality. It is crucial to implement alternative strategies to reach the most affected populations and to increase funding for the delivery of healthcare services in Afghanistan.

A Texting- and Internet-Based Self-Reporting System for Enhanced Vaccine Safety Surveillance With Insights From a Large Integrated Health Care System in the United States: Prospective Cohort Study.

BACKGROUND: SMS text messaging- and internet-based self-reporting systems can supplement existing vaccine safety surveillance systems, but real-world participation patterns have not been assessed at scale. OBJECTIVE: This study aimed to describe the participation rates of a new SMS text messaging- and internet-based self-reporting system called the Kaiser Permanente Side Effect Monitor (KPSEM) within a large integrated health care system. METHODS: We conducted a prospective cohort study of Kaiser Permanente Southern California (KPSC) patients receiving a COVID-19 vaccination from April 23, 2021, to July 31, 2023. Patients received invitations through flyers, SMS text messages, emails, or patient health care portals. After consenting, patients received regular surveys to assess adverse events up to 5 weeks after each dose. Linkage with medical records provided demographic and clinical data. In this study, we describe KPSEM participation rates, defined as providing consent and completing at least 1 survey within 35 days of COVID-19 vaccination. RESULTS: Approximately, 8% (164,636/2,091,975) of all vaccinated patients provided consent and completed at least 1 survey within 35 days. The lowest participation rates were observed for parents of children aged 12-17 years (1349/152,928, 0.9% participation rate), and the highest participation was observed among older adults aged 61-70 years (39,844/329,487, 12.1%). Persons of non-Hispanic White race were more likely to participate compared with other races and ethnicities (13.1% vs 3.9%-7.5%, respectively; P<.001). In addition, patients residing in areas with a higher neighborhood deprivation index were less likely to participate (5.1%, 16,503/323,122 vs 10.8%, 38,084/352,939 in the highest vs lowest deprivation quintiles, respectively; P<.001). Invitations through the individual's Kaiser Permanente health care portal account and by SMS text message were associated with the highest participation rate (19.2%, 70,248/366,377 and 10.5%, 96,169/914,793, respectively), followed by email (19,464/396,912, 4.9%) and then QR codes on flyers (25,882/2,091,975, 1.2%). SMS text messaging-based surveys demonstrated the highest sustained daily response rates compared with internet-based surveys. CONCLUSIONS: This real-world prospective study demonstrated that a novel digital vaccine safety self-reporting system implemented through an integrated health care system can achieve high participation rates. Linkage with participants' electronic health records is another unique benefit of this surveillance system. We also identified lower participation among selected vulnerable populations, which may have implications when interpreting data collected from similar digital systems.

Prevalence and factors contributing to mental health challenges among school-going adolescents: a case of a climate-vulnerable Manafwa Watershed in Uganda.

BACKGROUND: Globally, mental health challenges are common among school-going adolescents, with a prevalence of 50.2% and 43.6% for depression and anxiety disorders, respectively. In Northeastern Uganda, a prevalence of 26.6% and 8.6% for anxiety and depressive disorders respectively were reported among children. School-going adolescents are at higher risk of developing these mental health challenges and this could be worsened by natural disasters like landslides. We aimed to determine the prevalence and factors contributing to mental health challenges (having at least one of following; depression, anxiety, anger, disruptive behaviour and social concept) among school adolescents in the Manafwa Watershed area. METHODS: This was a cross-sectional study in 3 districts of the Manafwa watershed area (Bududa, Manafwa, and Butaleja). We selected school-going adolescents aged 13-18 years because of the nature of study tools. Mental health challenges (anxiety, depression, anger, disruptive behaviour and self-concept) were assessed using the Beck Youth Inventory-II. Descriptive statistics and inferential analysis were performed to determine factors associated with mental health challenges. RESULTS: A total of 762 adolescents participated, with a median age of 17 years (interquartile range =16-17 years). More than half of the students were females. The prevalence of mental health challenges was 65% with a (confidence interval) = 54.0% - 75.0%; the majority 44% of the participants had anxiety, and 31% had disruptive behaviour. Families with more than five children [adjusted odds ratio = 1.18, 95% confidence interval= 1.08-1.29, p value = <0.001] and substance abuse [adjusted odds ratio = 1.20, 95% confidence interval= 1.15-1.24, p value <0.001] were significantly associated with mental health challenges. CONCLUSION: The prevalence of mental health challenges among students was high with majority having anxiety and disruptive behaviour. Adolescents from families with more than five children and those with substance abuse were more likely to have mental health challenges. We therefore recommend that various stakeholders such as the Ministry of Health, and the Ministry of Education, design a curriculum that caters to the mental health needs of children. Family planning awareness, awareness on Government laws prohibiting alcohol and substance use, and parenting skills should be raised by the local leaders.

Polymedia Literacy and Other Ethical Considerations for Online Ethnographic Research on Social Networking Sites.

Drawing on the authors' own ethnographic research, this article discusses the importance of developing polymedia literacy as a key step toward ethical online research on social networking sites (SNS). Polymedia literacy entails the ability to critically analyze the vast landscape of SNS, their affordances, and users' social motivations for choosing specific SNS for their interactions. Internet researchers face several ethical challenges, including issues of informed consent, "public" and "private" online spaces, and data protection. Even when research ethics committees waive the need for a formal ethics approval process, researchers of online spaces need to ensure that their studies are conducted and presented in an ethical and responsible manner. This is particularly important in research contexts that pertain to vulnerable populations in online communities.

Initiation and/or re-initiation of drug use among people who use drugs in Vancouver, Canada from 2021 to 2022: a prospective cohort study.

OBJECTIVES: Widespread health service disruptions resulting from the COVID-19 pandemic coincided with a dramatic increase in overdose deaths among people who use drugs (PWUD) in Vancouver, Canada. Those with a history of injection drug use are known to be at heightened risk of substance-associated harms. Drug use patterns and associated sociodemographic and health care utilization trends have been understudied in this population since the pandemic onset. We sought to understand patterns of drug use initiation and/or re-initiation among people with a history of injection drug use (IVDU). METHODS: Data were obtained from three harmonized prospective cohort studies of PWUD in Vancouver. Participants with a lifetime history of IVDU who responded to a survey between June 2021 and May 2022 were included. The primary outcome variable was a composite of substance use initiation and re-initiation over the study period, labelled as drug (re)-initiation. A multivariable generalized linear mixed-effects model was used to examine factors associated with self-reported (re)-initiation of substance use over the past six months. RESULTS: Among 1061 participants, the median age was 47 years at baseline and 589 (55.5%) identified as men. In total, 183 (17.2%) participants reported initiating and/or re-initiating a drug, with 44 (4.1%) reporting new drug initiation and 148 (14.0%) reporting drug re-initiation (9 participants responded 'yes' to both). Overall, unregulated stimulants (e.g., crystal methamphetamine and cocaine) were the most common drug class (re-)initiated (n = 101; 55.2%), followed by opioids (n = 74; 40.4%) and psychedelics (n = 36; 19.7%). In the multivariable analysis, (re-)initiation of drug use was independently associated with recent IVDU (adjusted odds ratio [AOR] 2.62, 95% confidence interval [CI] 1.02, 6.76), incarceration (AOR 3.36, CI 1.12, 10.14) and inability to access addiction treatment (AOR 4.91, 95% CI 1.22, 19.75). CONCLUSIONS: In an era impacted by the intersecting effects of the COVID-19 pandemic and the overdose crisis, nearly one in five PWUD with a history of IVDU began using a new drug and/or re-started use of a previous drug. Those who reported drug (re-)initiation exhibited riskier substance use behaviours and reported difficulty accessing treatment services. Our findings underscore the need to provide additional resources to support this high-risk population.

[Population structure and fruiting ability of Rosa persica]. / 单叶蔷薇种群结构与结实能力.

We analyzed age structure and dynamics, spatial distribution patterns, and reproductive capabilities of four Rosa persica populations in Xinjiang, to evaluate the survival status of the species and explore the reasons behind its endangerment. The results showed that the populations had fewer individuals in the youngest (Ⅰ) and oldest (Ⅵ-Ⅷ) age classes, with a predominance of middle-aged individuals, resulting in an irregular pyramid-shaped distribution, described as "high in the middle, low on both sides". The populations were generally growing, but were susceptible to external environmental disturbances (Vpi'＞0, Pmax＞0). The mortality rate (qx) and vanish rate (Kx) peaked at age Ⅴ, leading to a sharp decline in plant abundance. The life expectancy (ex) decreased progressively with the increases of age class, reaching its lowest at age Ⅷ, which indicated minimal vitality at this stage. A time sequence analysis predicted a future dominance of individuals at age Ⅴ-Ⅷ, suggesting an aging trend. Spatially, the four populations were predominantly clumped, with the intensity of clumping ranked from highest to lowest as P4, P3, P1, and P2. P3 and P4 exhibited better reproductive capabilities than P1 and P2. There was a significant positive correlation between hundred-fruit weight and plant height and crown width, and between total seed number and crown width and hundred-fruit weight.

COVID-19 Disease and Chronic Health Outcomes Associated with Nicotine Use in a Great Plains Tribal Community: A Community-Based Study.

BACKGROUND: The Cheyenne River Sioux Tribe (CRST) is affected by high nicotine use and disease burden. Understanding nicotine exposure is important to recognize what groups may be at higher risk for negative health outcomes, including COVID-19. OBJECTIVE: To compare self-reported health outcomes and nicotine use between exclusive electronic cigarette (e-cig) users, users of combustible cigarettes, dual e-cig/cigarette users, and nonusers among adult residents on the CRST. METHODS: The CRST "COVID-19 - Wayakta He study" ("Are you on guard against COVID-19?") recruited 562 participants on the reservation who filled out a 97-item survey. Regression models were used to analyze nicotine exposure, demographic characteristics, and health outcomes. RESULTS: Prevalence of nicotine use among participants was 53%. Reported median puffs per day was 15 for e-cig, 100 for cigarette, and 20 for dual users (p < 0.001). The odds of having COVID-19 were lower for nicotine users compared to nonusers (p < 0.001). The odds of hypertension (p = 0.04) and high cholesterol (p = 0.03) were lower for nicotine users compared to nonusers. The proportional odds were higher for nicotine users for longer COVID-19 recovery time (p = 0.046) and lower for more severe COVID-19 infection (p = 0.001). SIGNIFICANCE: This study provides critical data on self-reported COVID-19, chronic disease outcomes, and exposure to commercial nicotine products. Results from this unique Tribal community-driven study with a large sample size (N = 562 participants from 289 households) will help understand the role that environmental exposures played on increased COVID-19 mortality, help target public health interventions, and inform Tribal public health policies on emergency preparedness and exposure analyses.

Trade and socioeconomic importance of an invasive giant snail in the endemic-rich island of São Tomé, Central Africa.

Managing invasive species is crucial to mitigate their negative impacts on ecosystems, yet conflicts may arise when their social benefits are disregarded. Human pressure on the endemic-rich forests of São Tomé has been high since the island was discovered by the Portuguese in the 15th century, and numerous species have been introduced. These include the invasive West African giant land snail (Archachatina marginata), which was introduced in the mid-20th century, is now widespread on the island, and is a potential threat to native flora and fauna. We assessed the frequency of consumption of this species and its socioeconomic importance to people across the island with household questionnaires, focus group discussions, and semistructured interviews. We explored the prevalence and potential drivers of use (e.g., wealth, household composition, and diversity of occupations) and characterized the commodity chain to identify demographic groups linked to the snail trade. We interviewed 672 people (1 person per household), conducted 6 focus groups, and interviewed 80 key actors belonging to 5 subcategories. The snail was the most widely consumed bushmeat and an important source of income, particularly for women and unemployed youth. Insecure and scarce livelihood alternatives, mostly in rural areas, were reported as drivers for trade involvement. Snail harvesting was more frequent in poorer households with low occupational diversity. Selling tended to occur in households that were well-established in the community and had a higher proportion of children. Both were stimulated by the proximity of communities to the native forest. Buying snails was common in all demographic groups, but it was linked to wealth and occupational diversity. Interventions to manage the impact of this introduced species on the valuable ecosystems of the island should involve multiple sectors of society to ensure societal support. This requires robust consideration of the welfare of vulnerable demographic groups that benefit from the species.

Importancia socioeconómica y comercial de un caracol invasor en la isla rica en endemismos de Santo Tomé, África Central Resumen La gestión de las especies invasoras es crucial para mitigar sus efectos negativos en los ecosistemas, aunque pueden surgir conflictos cuando no se tienen en cuenta sus beneficios sociales. La presión humana sobre los bosques de Santo Tomé, ricos en endemismos, ha sido alta desde que la isla fue colonizada por los portugueses en el siglo XV y desde entonces se han introducido numerosas especies. Una de ellas es el caracol terrestre gigante de África Occidental (Archachatina marginata), introducido a mediados del siglo XX y que ahora tiene una distribución amplia en la isla y es una amenaza potencial para la flora y la fauna autóctonas al ser invasor. Evaluamos la frecuencia de consumo de esta especie y su importancia socioeconómica para la población de toda la isla mediante encuestas en hogares, grupos de discusión y entrevistas semiestructuradas a actores clave de cinco categorías. Exploramos la prevalencia y los posibles factores impulsores del consumo (por ejemplo, la riqueza, la composición de los hogares y la diversidad de ocupaciones) y caracterizamos la cadena comercial para identificar los grupos demográficos vinculados al comercio de caracoles. Entrevistamos a 672 personas (una persona por hogar), realizamos seis grupos de discusión y entrevistamos a 80 actores clave. El caracol fue la carne de caza más consumida y una importante fuente de ingresos, sobre todo para las mujeres y los jóvenes desempleados. La inseguridad y la escasez de medios de subsistencia, sobre todo en las zonas rurales, fueron los factores que impulsaron la participación en el mercado. La colecta de caracoles fue más frecuente en los hogares más pobres y con escasa diversidad ocupacional. La venta tendía a producirse en hogares bien establecidos en la comunidad y con una mayor proporción de niños. Ambos factores se vieron estimulados por la proximidad de las comunidades al bosque nativo. La compra de caracoles fue común en todos los grupos demográficos, pero estuvo vinculada a la riqueza y a la diversidad ocupacional. Las intervenciones para gestionar el impacto de esta especie introducida en los valiosos ecosistemas de la isla deben implicar a múltiples sectores de la sociedad para garantizar su apoyo. Para ello es necesario tener muy en cuenta el bienestar de los grupos demográficos vulnerables que se benefician de la especie.
