Attitudes Toward School-Based Surveillance of Adolescents' Social Media Activity: Convergent Parallel Mixed Methods Survey

BACKGROUND

US schools increasingly implement commercially available technology for social media monitoring (SMM) of students, purportedly to address youth mental health and school safety. However, little is known about how SMM is perceived by stakeholders, including the students who are the focus of these efforts.

OBJECTIVE

We aimed to assess attitudes toward SMM in schools among 4 stakeholder groups and examine reasons for holding supportive, neutral, or unsupportive views toward the technology. We also sought to explore whether any differences in attitudes were associated with binary sex, race, ethnicity, sexual orientation, or gender identity.

METHODS

In October 2019, we conducted a convergent parallel mixed methods web-based survey of young adults (aged 18-22 y; n=206), parents (n=205), teachers (n=77), and school administrators (n=41) via Qualtrics web-based panels. We included Likert-type survey items to assess perceived benefits, risks, and overall support of SMM in schools and test for differences based on stakeholder group or demographic characteristics. We also included open-ended questions, and the responses to these items were analyzed using thematic content analysis of reasons given for holding supportive, neutral, or unsupportive views.

RESULTS

The tests of group differences showed that young adults perceived lower benefit (P<.001) as well as higher risk (P<.001) and expressed lower overall support (P<.001) of the use of SMM in schools than all other stakeholder groups. Individuals identifying as nonheterosexual also perceived lower benefit (P=.002) and higher risk (P=.02) and expressed lower overall support (P=.02) than their heterosexual counterparts; respondents who identified as people of racial and ethnic minorities also perceived higher risk (P=.04) than their White counterparts. Qualitative thematic content analysis revealed greater nuance in concerns about SMM. Specifically, the primary reasons given for not supporting SMM across all stakeholder groups were (1) skepticism about its utility, (2) perceived privacy violations, and (3) fears of inappropriate or discriminatory use of the data. Within the young adult group in particular, concerns were also raised about (4) unintended and adverse consequences, including the erosion of trust between students and school institutions and administrators, and the chronic adverse effects of constant or prolonged surveillance. Thematic analysis also showed that individuals in every stakeholder group who indicated overall support of SMM were likely to cite the potential for enhanced school safety as the reason. Young adults' overall stances toward SMM were the most polarized, either strongly for or strongly against SMM, and responses from teachers indicated similar polarization but more often favored support of SMM in schools.

CONCLUSIONS

This study found differing perspectives among stakeholder groups regarding SMM in schools. More work is needed to assess the ways in which this type of surveillance is being implemented and the range and complexity of possible effects, particularly on students.

The Relationship Between Cannabis Use and Self-Reported Trait Anger in Treatment-Seeking Young People

Objective: Trait anger has been shown to be predictive of emotion-focused coping and alcohol use. Yet, the connection between cannabis use and trait anger remains poorly characterized. The present study sought to investigate the relationship between cannabis use and self-reported trait anger in youth seeking substance use treatment. Methods: A retrospective chart review was conducted on youth (n=168) aged 14-26 presenting for an initial evaluation at an outpatient substance use treatment program. Patients self-reported trait anger score (TAS) and lifetime, recent, and Diagnostic and Statistics Manual-5th Edition diagnostic status of cannabis use were assessed. Clinician-coded psychiatric and substance use patterns were collected, along with urine carboxy delta-9-tetrahydrocannabinol (THC) concentration levels. Additional measures of anxiety, depression, and demographic variables were assessed. Results: Higher self-reported TAS were associated with cannabis use, cannabis use disorder (CUD), and more recent and frequent cannabis use. The presence of a CUD was independently associated with TAS after controlling for the presence of other substance use disorders and co-occurring depression and anxiety disorders. Higher urine THC concentration levels were associated with higher TAS. Conclusions: Findings support an association between heavy, chronic cannabis use and elevated self-reported trait anger at intake. There may be important neurological consequences of heavy, chronic cannabis use that impact anger regulation. It is also plausible that trait anger maybe a predisposing factor for elevated cannabis use. Better controlled prospective research is needed to help determine directionality. Treatment programs should target both cannabis use and anger regulation in youth.

Examining the clinical correlates of conduct disorder in youth with bipolar disorder

BACKGROUND

Conduct Disorder (CD) is highly comorbid with Bipolar Disorder (BP) and this comorbidity is associated with high morbidity and dysfunction. We sought to better understand the clinical characteristics and familiality of comorbid BP + CD by examining children with BP with and without co-morbid CD.

METHODS

357 subjects with BP were derived from two independent datasets of youth with and without BP. All subjects were evaluated with structured diagnostic interviews, the Child Behavior Checklist (CBCL), and neuropsychological testing. We stratified the sample of subjects with BP by the presence or absence of CD and compared the two groups on measures of psychopathology, school functioning, and neurocognitive functioning. First-degree relatives of subjects with BP +/- CD were compared on rates of psychopathology in relatives.

RESULTS

Subjects with BP + CD compared to BP without CD had significantly more impaired scores on the CBCL Aggressive Behavior (p < 0.001), Attention Problems (p = 0.002), Rule-Breaking Behavior (p < 0.001), Social Problems (p < 0.001), Withdrawn/Depressed clinical scales (p = 0.005), the Externalizing Problems (p < 0.001), and Total Problems composite scales(p < 0.001). Subjects with BP + CD had significantly higher rates of oppositional defiant disorder (ODD) (p = 0.002), any SUD (p < 0.001), and cigarette smoking (p = 0.001). First-degree relatives of subjects with BP + CD had significantly higher rates of CD/ODD/ASPD and cigarette smoking compared to first-degree relatives of subjects without CD.

LIMITATIONS

The generalization of our findings was limited due to a largely homogeneous sample and no CD only comparison group.

CONCLUSIONS

Given the deleterious outcomes associated with comorbid BP + CD, further efforts in identification and treatment are necessary.

A systematic review of substance use screening in outpatient behavioral health settings

OBJECTIVE

Despite the frequent comorbidity of substance use disorders (SUDs) and psychiatric disorders, it remains unclear if screening for substance use in behavioral health clinics is a common practice. The aim of this review is to examine what is known about systematic screening for substance use in outpatient behavioral health clinics.

METHODS

We conducted a PRISMA-based systematic literature search assessing substance use screening in outpatient adult and pediatric behavioral health settings in PubMed, Embase, and PsycINFO. Quantitative studies published in English before May 22, 2020 that reported the percentage of patients who completed screening were included.

RESULTS

Only eight articles met our inclusion and exclusion criteria. Reported prevalence of screening ranged from 48 to 100%, with half of the studies successfully screening more than 75% of their patient population. There were limited data on patient demographics for individuals who were and were not screened (e.g., gender, race) and screening practices (e.g., electronic versus paper/pencil administration).

CONCLUSIONS

The results of this systematic review suggest that successful screening for substance use in behavioral health settings is possible, yet it remains unclear how frequently screening occurs. Given the high rates of comorbid SUD and psychopathology, future research is necessary regarding patient and clinic-level variables that may impact the successful implementation of substance use screening. Trial registry A methodological protocol was registered with the PROSPERO systematic review protocol registry (ID: CRD42020188645).

A systematic review of virtual reality therapies for substance use disorders: Impact on secondary treatment outcomes

BACKGROUND AND OBJECTIVES

Virtual reality (VR) therapy may be an effective tool in treating urges and cravings in substance use disorder (SUD). Given the high co-occurrence of difficulties with mood, anxiety, and emotional dysregulation with SUD, this review sought to examine the extant literature on the efficacy of VR for SUD in improving these secondary treatment outcomes.

METHODS

A systematic literature review was conducted following PRISMA guidelines in PubMed, PsychInfo, and Embase. Studies were included if they utilized immersive VR, were conducted with individuals with substance use disorder/dependence/misuse, and included measures of mood, anxiety, depression, emotional dysregulation, or retention in treatment.

RESULTS

Seven articles met our inclusion criteria. Five studies were conducted on patients using nicotine and utilized a cue-exposure intervention. VR was effective at reducing substance use and cravings in the majority of studies. Results on the efficacy of VR for improving mood, anxiety, and emotional regulation were mixed. Work examining retention in treatment was limited.

DISCUSSION AND CONCLUSIONS

VR for SUD has the potential to improve mood and anxiety symptoms as well as retention in treatment for patients with SUD, particularly if the therapy targets these psychological symptoms. Future studies examining components of VR for SUD in individuals with drug use disorders, as well as examinations of targeted interventions for associated mood, emotional dysregulation, and retention in treatment, are necessary.

SCIENTIFIC SIGNIFICANCE

This is the first systematic review of the impact of VR on mood, anxiety, and emotional dysregulation for individuals with substance use.

95 EXPLORING HIP FRACTURE OUTCOMES IN POST-ACUTE REHABILITATION: A MULTI-SITE AUDIT

Background

In 2020, 28% of all hip fractures in Ireland were discharged to off-site rehabilitation. The annual Irish Hip Fracture Database (IHFD) report captures patient outcomes at the point of acute discharge however patient outcomes at discharge from offsite rehabilitation are unknown.

Methods

A multi-site retrospective audit was completed examining hip fracture outcomes for patients admitted to four post-acute rehabilitation hospitals during 2021, using IHFD HIPE portals as well as local databases. Descriptive statistics including demographics, pre-fracture mobility as well as outcomes measured including acute length of stay, rehabilitation length of stay, discharge destination and independence with mobility on discharge from rehabilitation. A comparison analysis between sites was completed.

Results

A total of 445 patients were admitted post hip fracture to the four rehabilitation hospitals in 2021. Most were female (69%, n=307), mean age 82.5, 49% lived alone and most (55%) had low pre-fracture mobility as measured by New Mobility Score of 0-6. The mean acute length of stay was 11.8 days and rehabilitation stay 37.6 days. Most (90.2% of complete data, n=333) discharged home, 4.5% (n=17) were transferred to hospital, 3.2% (n=12) were newly admitted to nursing home and 1% (n=4) died. Most (82.2% of complete data, n=256) were independently mobile (CAS 6) at discharge from rehabilitation. There was no significant difference in patient profile between sites however there were significant difference in both acute length of stay (median range 8-13days) as well as rehabilitation length of stay (median range 16-39days).

Conclusion

The findings of this audit provide a new perspective on recovery post hip fracture and insight into longer term hip fracture outcomes. It shows that data collection is feasible in off-site rehabilitation units and should be considered for inclusion in the IHFD. Further work could explore the establishment of standards of care in the post-acute phase of hip fracture rehabilitation.

Prevention and early treatment of the long-term physical effects of COVID-19 in adults: design of a randomised controlled trial of resistance exercise-CISCO-21

Background

Coronavirus disease-19 (COVID-19) infection causes persistent health problems such as breathlessness, chest pain and fatigue, and therapies for the prevention and early treatment of post-COVID-19 syndromes are needed. Accordingly, we are investigating the effect of a resistance exercise intervention on exercise capacity and health status following COVID-19 infection.

Methods

A two-arm randomised, controlled clinical trial including 220 adults with a diagnosis of COVID-19 in the preceding 6 months. Participants will be classified according to clinical presentation: Group A, not hospitalised due to COVID but persisting symptoms for at least 4 weeks leading to medical review; Group B, discharged after an admission for COVID and with persistent symptoms for at least 4 weeks; or Group C, convalescing in hospital after an admission for COVID.

Participants will be randomised to usual care or usual care plus a personalised and pragmatic resistance exercise intervention for 12 weeks. The primary outcome is the incremental shuttle walks test (ISWT) 3 months after randomisation with secondary outcomes including spirometry, grip strength, short performance physical battery (SPPB), frailty status, contacts with healthcare professionals, hospitalisation and questionnaires assessing health-related quality of life, physical activity, fatigue and dyspnoea.

Discussion

Ethical approval has been granted by the National Health Service (NHS) West of Scotland Research Ethics Committee (REC) (reference: GN20CA537) and recruitment is ongoing. Trial findings will be disseminated through patient and public forums, scientific conferences and journals.

O-187 An analysis of the outcome of 11,712 men applying to be sperm donors at Cryos International in Denmark and the USA

Study question

Is the outcome of donor recruitment influenced by the country in which recruitment took place or the initial ID-release choice of applicants?

Summary answer

More applicants are accepted as donors in Denmark than the USA and those who choose ID release are more frequently accepted than those who don’t.

What is known already

The successful recruitment of sperm donors is essential to provide a range of Assisted Reproductive Technologies (ART) which rely upon donor sperm. However, while much has been written about the medical screening and assessment of sperm donors from a safety perspective, relatively little has been written about the process of recruiting donors and how it works in practice. There are differences in attitudes between donors who choose to allow their identity to be released to any donor conceived people (ID-release) compared to those who don’t (non ID-release). Therefore, we reasoned this may also influence the likelihood of them being recruited.

Study design, size, duration

A total of 11,712 men applied to be sperm donors at Cryos International in Denmark and the USA during 2018 and 2019.

Participants/materials, setting, methods

Anonymised records of all donor applicants were examined to assess the number passing through (or lost) at each stage of the recruitment process. Statistical analysis was carried out by Chi Squared test, using Graphpad Prism (San Diego, USA) to examine differences between location (Denmark or USA) and/or donor type (ID-release vs non-ID release).

Main results and the role of chance

Few applicants (3.79%) were accepted as donors and had samples released for use. This was higher in Denmark (6.53%) than the USA (1.03%) (χ2 = 243.2; 1df; z = 15.60; p &lt; 0.0001) and was higher in donors who opted at the outset to be ID-release (4.70%) compared to those who didn’t (3.15%) (χ2 = 18.51; 1df; z = 4.303; p &lt; 0.0001). Most potential donors were lost during recruitment because they: (i) withdrew, failed to respond, did not attend an appointment, or return a questionnaire (54.91%); (ii) reported a disqualifying health issue or failed a screening test (17.41%); (iii) did not meet the eligibility criteria at the outset (11.71%); or (iv) had semen quality which was not adequate (11.20%). In each case, there were statistically significant differences between countries and the donor’s initial ID choice. During recruitment, some donors decided to change ID-type. There were no country differences in the frequency in which this occurred (χ2 = 0.2852; 1df; z = 0.5340; p = 0.5933), but it was more common for donors to change from non-ID release to ID release (27.19%) than the other way around (11.45%) (χ2 = 17.75; 1df; z = 4.213; p &lt; 0.0001) although movements in both directions did occur in both countries.

Limitations, reasons for caution

No information was available about the demographic characteristics of the applicants which may also have influenced their chances of being accepted as a donor (e.g., ethnicity, age etc). Donor recruitment procedures may differ in other locations according to local laws or guidelines.

Wider implications of the findings

A better understanding of when and why potential donors are lost in the recruitment process may help develop leaner and efficient pathways for interested donors and sperm banks. This could ultimately increase the number of donors recruited through enhanced information, support and reassurance during the recruitment process.

0344 Use of an Adjustable Bed Base Improves Sleep Quality and Duration

Introduction

The positional adjustment of a bed can potentially contribute to better sleep and alleviation of discomfort associated with a variety of medical conditions. As most studies in this area have focused on inclined sleeping for therapeutic purposes, understanding the impact of postural change on improving sleep among healthy individuals requires further research. This study compared sleep in an inclined position on an adjustable bed base to participants’ prior sleep on their original bed bases.

Methods

Healthy adults (61% female, ages 23-60) willing to sleep at an incline participated in an 8-week field study, using a pre-post intervention design. During the 4-week baseline period, participants used their regular bed base at home. During the 4-week intervention period, they used the Mattress Firm 600 Adjustable Base at home with head and/or feet raised (not flat). Sleep was measured objectively using SleepScore Max every night and by daily and pre-post self-report. Multilevel regression and paired t-tests were used to test for statistical significance.

Results

There were over 1,100 nights of tracked sleep across 26 participants. Objective sleep measurements showed many nightly improvements during the intervention compared to baseline: increased time in bed (+21 minutes, p=.003), total sleep time (+21 minutes, p=.001), and REM (+5 minutes, p=.009); less WASO, both in duration (-3 minutes, p=.046) and proportion of the night (p=.015); fewer awakenings (p=.034); and better sleep maintenance (p=.014). Improvements also were observed in 3 objective sleep quality measures: SleepScore, BodyScore, and MindScore (ps&lt;.05).Self-report measures revealed greater comfort and enjoyment when using the adjustable base, as well as perceived improvement in a variety of outcomes, including time to fall asleep and falling asleep within a preferred amount of time, ability to sleep through the night, sleep duration, sleep quality and satisfaction, and feeling more rested in the morning (ps&lt;.05).

Conclusion

Objectively-measured sleep and self-reported sleep improved in duration and quality when using the adjustable base compared to healthy adults’ original bed bases. Furthermore, qualitative and quantitative self-report results suggested that the intervention was perceived as a comfortable and enjoyable experience.

0343 In-person Expert Pillow Fitting Process Improves Sleep Quality and Duration

Introduction

The myriad of anecdotal claims about the benefits of different pillow types may complicate consumers’ ability to find a pillow that can support better sleep. Services that provide consumers with personalized recommendations may address this problem. This study examined the sleep of research participants using pillows selected during an in-store pillow fitting process compared to using their original pillows.

Methods

Healthy adults (71% female, ages 21-59) who reported interest in a new pillow participated in a 9-week field study using a pre-post intervention design. The intervention consisted of being guided through the Mattress Firm in-store pillow fitting process to be paired with a pillow that provided the best fit and support based on body type and sleeping position preferences. During the 4-week baseline period, participants used their regular pillow. Once they were fit for their new pillow, participants slept with that pillow for 5 weeks, including a 1-week adjustment period. Sleep was measured objectively using SleepScore Max every night and by daily and pre-post self-report. Multilevel regression and paired t-tests and were used to test for statistical significance.

Results

There were 722 nights of tracked sleep across participants (n=17). Objective sleep measurements showed nightly improvement in SleepScore, a measure of objective sleep quality (p=.003), longer time in bed (+13 minutes, p=.034),longer sleep duration (+16 minutes, p=.010), a lower proportion of the night awake after falling asleep (p=.009), and better sleep maintenance (p=.009). In addition, participants got more deep sleep (+5.6 minutes, p=.017) and showed improved BodyScore, a measure of deep sleep (p=.031). Self-reported measures showed improvements in pillow comfort and overall comfort in bed; perceived ability to sleep through the night; perceived reduction in number of awakenings and amount of time awake at night; better overall sleep quality; and feeling more well-rested in the morning when using the fitted pillows compared to baseline (all ps &lt;.05).

Conclusion

Objective and self-reported sleep improved among healthy adults using a pillow selected by an expert, in-person pillow fitting process. The results suggest that a pillow fitting process can improve sleep by helping individuals find a pillow that provides a personalized fit and optimal comfort.

The Impact of Pharmacotherapy of Childhood-Onset Psychiatric Disorders on the Development of Substance Use Disorders

Background and Objective: Child- and adolescent-onset psychopathology is known to increase the risk for developing substance use and substance use disorders (SUDs). While pharmacotherapy is effective in treating pediatric psychiatric disorders, the impact of medication on the ultimate risk to develop SUDs in these youth remains unclear. Methods: We conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) systematic review of peer-reviewed literature published on PubMed through November 2021, examining pharmacological treatments of psychiatric disorders in adolescents and young adults and their effect on substance use, misuse, and use disorder development. Results: Our search terms yielded 21 studies examining the impact of pharmacotherapy and later SUD in attention-deficit/hyperactivity disorder (ADHD), two studies on Major Depressive Disorder, and three studies on psychotic disorders. The majority of these studies reported reductions in SUD (N = 14 sides) followed by no effects (N = 10) and enhanced rates of SUD (N = 2). Studies in ADHD also reported that earlier-onset and longer-duration treatment was associated with the largest risk reduction for later SUD. Conclusions: Overall, pharmacological treatments for psychiatric disorders appear to mitigate the development of SUD, especially when treatment is initiated early and for longer durations. More studies on the development of SUD linked to the effects of psychotherapy alone and in combination with medication, medication initiation and duration, adequacy of treatment, non-ADHD disorders, and psychiatric comorbidity are necessary.

222 OLDER ADULT INPATIENTS’ PERCEPTIONS OF PROGRESSIVE RESISTANCE TRAINING IN A SPECIALIST GERIATRIC REHABILITATION SETTING

Background

Progressive resistance training (PRT) has the potential to reduce age-related disability and has been proven to benefit the older adult in a variety of ways. PRT is prescribed routinely by physiotherapists for frail older adults in an inpatient setting. To date little is known of their experiences engaging in PRT. This study aimed to explore older adult inpatients’ perceptions and experience of PRT as part of their overall physiotherapy program in a Specialised Geriatric Rehabilitation Unit.

Methods

The study had a qualitative design. Semi-structured interviews explored experiences and perceptions of PRT along with motivators and barriers to participation. Interviews were face to face and conducted in the unit. Data was analysed using thematic analysis. 11 frail older inpatients with orthogeriatric (n = 5), neurological (n = 2), general surgical (n = 2) and general medical (n = 2) diagnoses were interviewed.

Results

The study identified three overarching themes: Acceptability, Facilitators and Barriers. In the category of Acceptability participants identified the subthemes: (1) PRT is challenging, (2) PRT is Rewarding and (3) PRT is Enjoyable. In the category of Facilitators, the following subthemes emerged: (4) Positive outcomes as motivators and (5) Supervision is necessary for engagement. In the category of Barriers, (6) Low self-efficacy beliefs and (7) the Negative effects of PRT, such as pain and fatigue affected participation.

Conclusion

Frail older inpatients find PRT to be an acceptable form of exercise. It is perceived to be challenging, but rewarding and enjoyable for most. Participants were motivated to participate in PRT by the positive outcomes (improved strength, general health, function, independence, confidence) they experienced. They felt supervision from professionals with medical expertise was essential to participation; and had low self-efficacy beliefs surrounding independent practice; fearing falling and causing harm. Pain and fatigue also impacted participation.

Perinatal mental health services for mothers from ethnic minority and migrant backgrounds

Perinatal mental health disorders are among the most common morbidities of the perinatal period with considerable adverse effects on mothers and their offspring. Members of ethnic minority groups, particularly those from migrant backgrounds, are at higher risk of developing mental illness with evidence of ongoing inequality in access to support. We will present an exploratory mixed-methods study scoping ethnic minority and migrant women's experiences accessing perinatal mental health services in the UK. Results showed how women perceived access to services as very challenging and how they experienced ‘suffering in silence', a ‘need for a safe space to talk and to be listened to', and a ‘need of finding other women like them'. We will complement these findings with the lessons learned from a related project, a three-site European study (ORAMMA) evaluating the feasibility of implementing an integrated perinatal care model for migrant mothers comprising maternity peer supporters (MPSs)-women from migrant backgrounds who had lived in the country for a longer time and were trained to support other migrant women during the childbearing continuum-. Results showed that MPSs supported migrant women accessing maternity care, overcoming language barriers, and advocating for them in their encounters with healthcare professionals. Besides, they provided emotional support and increased women's confidence, helping them overcome loneliness, encouraging them to build relationships with others and promoting bonding with the new baby. Bringing these two projects together, we will discuss how MPSs have the potential to help overcome barriers that immigrant women experience in seeking perinatal mental health and how the benefits of maternity peer supporters have the potential to reduce perinatal mental health risks amongst migrant mothers. Findings will point to the need for future research to evaluate the direct impacts of MPSs on immigrant's mother perinatal mental health.

P–537 What is the attitude of gamete donors towards expanded genetic testing

Study question

What is the opinion of gamete donors on extended carrier screening in Denmark and in US?

Summary answer

This study showed that the overwhelming majority of the donors were very positive towards genetic testing in general and the expanded carrier screening.

What is known already

There is a lack of empirical studies on the experiences of and attitudes of donors towards expanded carrier screening (ECS) (Amor et al. 2018). Oocyte donors in a Spanish clinic were surprised by the information on testing and the possibility of being carriers (Abuli et al., 2016). After adequate genetic counselling before and after the test, the results of testing did not seem to have a meaningful emotional or psychological impact on the donors.

Study design, size, duration

A questionnaire was emailed to all active sperm donors in a sperm bank in Denmark and in a sperm bank in US.

Participants/materials, setting, methods

A total of 393 donors received the email of which 233 donors completed the questionnaire, 196 in Denmark (response rate of 60.7%) and 37 in the United States (response rate of 52.9%).

Main results and the role of chance

We systematically compared the US and DK donors and ID-release versus non-ID-release donors for all characteristics and items. ID-release donors with a partner significantly more informed their partner about their donor status than non-ID-release donors (90.5% vs. 72.4%, p 0.027). ID-release donors significantly more intended to tell their own children (57.5% vs. 21.2%, p 0.001). ID-release donors significantly more thought about their potential donor children (56.2% vs. 35.0%; p 0.002) and significantly more likely to want information on whether a pregnancy occurred from their donation (70.6% vs. 55.0%, p 0.017). In addition, they also significantly more wished to obtain information about the children conceived with their sperm: the number of children (64.0% vs. 50.0%, p 0.048), their gender (40% vs. 26.2%, p 0.042), and their health (59.3% vs. 42.5%, p 0.018). The ID-release donors were much less likely than the other type not to want any information (19.3% vs. 32.5%, p 0.034). This general attitude is extended to the wish to be informed if a child with a hereditary disease is born after using their sperm. The ID-release donors were more likely to desire contact if their genetic child was diagnosed with a genetic disease (73.9% vs. 55.0%, p 0.003).

Limitations, reasons for caution

The main element that makes the study unique (i.e., the choice between ID-release and non-ID-release) also renders the generalization of the findings more difficult. Wider implications of the findings: A better understanding of the attitude among gamete doners will possibly guide future legislation and ensure the safety and welfare of the donors too.

Social Media Surveillance in Schools: Rethinking Public Health Interventions in the Digital Age

Growing public concern about student safety and well-being has led schools and school districts to contract private companies to implement new technologies that target and surveil students' activity on social media websites. Although innovative solutions for addressing student safety and health are needed, it is unclear whether the implementation of social media surveillance in schools is an effective strategy. Currently, there is no evidence to support the claims made by social media surveillance companies, as well as the schools that hire them, that these technologies can address the myriad of public health issues facing today's students. Instead, these digital surveillance systems may only serve to exacerbate the problems that youth-especially those from historically marginalized groups-already face.

Disentangling the Social Context of Nonmedical Use of Prescription Stimulants in College Students

BACKGROUND AND OBJECTIVES

The aim of this study was to investigate the social context of nonmedical use of prescription stimulants (NMUPS) among college students who endorsed NMUPS with co-occurring substance use disorders (SUD) compared with those without co-occurring SUDs.

METHODS

Presented here are new analyses based on data previously collected from college students aged 18 to 28 years derived from the Boston metropolitan area who endorsed NMUPS (N = 100) at least once in their lifetime. Differences between those with lifetime history of SUD (N = 46) and without a history of SUD (N = 54) on the Massachusetts General Hospital ADHD Medication Misuse and Diversion Assessment were analyzed using the Student t test, the Pearson χ² test, and the Wilcoxon rank-sum test.

RESULTS

College students who endorsed NMUPS with co-occurring SUD were more likely than those without SUD to have bought or traded stimulants, bought or traded in their car, used at parties with drugs/alcohol, or used intranasally (all P < .05). Intranasal administration was common (38% of all students endorsing NMUPS) and was associated with misuse at a party and simultaneous use with cocaine (P = .04), marijuana (P < .001), and alcohol (P < .001), compared with only oral use.

DISCUSSION AND CONCLUSIONS

Notable characteristics were identified among individuals who engaged in NMUPS in the type, amount, cost, and ascertainment of stimulants.

SCIENTIFIC SIGNIFICANCE

The concurrence of SUD and/or intranasal administration appear to represent a more severe phenotype of NMUPS that should be considered in the implementation of future prevention and intervention protocols on college campuses. (Am J Addict 2020;29:476-484).

ATP synthase F1 subunits recruited to centromeres by CENP-A are required for male meiosis

The histone H3 variant CENP-A epigenetically defines the centromere and is critical for chromosome segregation. Here we report an interaction between CENP-A and subunits of the mitochondrial ATP synthase complex in the germline of male Drosophila. Furthermore, we report that knockdown of CENP-A, as well as subunits ATPsyn-α, -βlike (a testis-specific paralogue of ATPsyn-β) and -γ disrupts sister centromere cohesion in meiotic prophase I. We find that this disruption is likely independent of reduced ATP levels. We identify that ATPsyn-α and -βlike localise to meiotic centromeres and that this localisation is dependent on the presence of CENP-A. We show that ATPsyn-α directly interacts with the N-terminus of CENP-A in vitro and that truncation of its N terminus perturbs sister centromere cohesion in prophase I. We propose that the CENP-A N-terminus recruits ATPsyn-α and -βlike to centromeres to promote sister centromere cohesion in a nuclear function that is independent of oxidative phosphorylation.

The histone H3 CENP-A is known to play a role during meiosis but its role in the testes in the fly is unknown. Here, the authors identify the mitochondrial metabolic protein complex ATP synthase F₁ as interacting with CENP-A, promoting centromere cohesion during meiosis and affecting fly fertility.

Cost-effectiveness of indacaterol/glycopyrronium in comparison with salmeterol/fluticasone combination for patients with moderate-to-severe chronic obstructive pulmonary disease: a LANTERN population analysis from Singapore

INTRODUCTION

In light of the growing evidence base for better clinical results with the use of the dual bronchodilator indacaterol/glycopyrronium (IND/GLY) over inhaled corticosteroid-containing salmeterol/fluticasone combination (SFC), this study aimed to evaluate the cost-effectiveness of IND/GLY over SFC in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) who are at low risk of exacerbations, in the Singapore healthcare setting.

METHODS

A previously published patient-level simulation model was adapted for use in Singapore by applying local unit costs. The model was populated with clinical data from the LANTERN and ECLIPSE studies. Both costs and health outcomes were predicted for the lifetime horizon from a payer's perspective and were discounted at 3% per annum. Costs were expressed in 2015 USD exchange rates. Uncertainty was assessed through probabilistic sensitivity analysis.

RESULTS

Compared to SFC, use of IND/GLY increased mean life expectancy by 0.316 years and mean quality-adjusted life years (QALYs) by 0.246 years, and decreased mean total treatment costs (drug costs and management of associated events) by USD 1,474 over the entire lifetime horizon. IND/GLY was considered to be 100% cost-effective at a threshold of 1 × gross domestic product per capita. The cost-effectiveness acceptability curve showed that IND/GLY was 100% cost-effective at a willingness-to-pay threshold of USD 0 (additional cost) when compared to SFC.

CONCLUSION

IND/GLY was estimated to be highly cost-effective compared to SFC in patients with moderate-to-severe COPD who are not at high risk of exacerbations in the Singapore healthcare setting.

Metastatic gestational choriocarcinoma: a masquerader in obstetrics

We describe a case of a 36-year-old woman presenting with vaginal bleeding and suboptimally rising serum human chorionic gonadotropin levels, who was investigated for a pregnancy of unknown location. Ultrasonography, laparoscopy and dilatation and curettage failed to reveal signs of an intra-uterine or intra-abdominal pregnancy. Following computed tomography imaging, a mediastinal mass was histologically determined to be a gestational choriocarcinoma. Following surgical resection and chemotherapy, the patient recovered and proceeded to have a successful intra-uterine pregnancy. We describe this exceptionally rare case and emphasise the importance of follow-up of hCG levels in pregnancy of unknown location.

AxGxE: Using Flies to Interrogate the Complex Etiology of Neurodegenerative Disease

Progressive and late-onset neurological disorders such as Parkinson's disease and Alzheimer's disease affect up to 50 million people globally-a number postulated to double every 20 years in a continually aging population. While predisposing allelic variants in several genes clearly confer risk, individual age and specific environmental influences are equally important discriminators of disease onset age and progression. However, none of these factors can independently predict disease with significant precision. Therefore, we must actively develop models that accommodate contributions from all factors, potentially resulting in an A × G × E (age-gene-environment) metric that reflects individual cumulative risk and reliably forecasts disease outcomes. This effort can only be enabled by a deep quantitative understanding of the contribution of these factors to neurodegenerative disease, both individually and in combination. This is also an important consideration because neuronal loss typically precedes clinical presentation and disease-modifying therapies are contingent on early diagnosis that is likely to be informed by an accurate estimation of individual risk. Although epidemiological studies continue to make strong advances in these areas with the advent of powerful "omics"-based approaches, systematic phenotypic modeling of AxGxE interactions is currently more feasible in model organisms such as Drosophila melanogaster where all three parameters can be manipulated with manageable experimental burden. Here, we outline the advantages of using fruit flies for investigating these complex interactions and highlight potential approaches that might help synthesize existing information from diverse fields into a cogent description of age-dependent, environmental, and genetic risk factors in the pathophysiology of neurological disorders.

Patient Satisfaction and Acceptability: A Journey through an Ambulatory Gynaecology Clinic in the West of Ireland

Ambulatory Gynaecology allows a 'see-and-treat' approach to managing gynaecological conditions, providing a more streamlined, integrated care pathway than the traditional gynaecology clinic and inpatient care model. This study was designed to assess patient satisfaction and acceptability of Ambulatory Gynaecology services in Mayo University Hospital, Castlebar, Ireland. It also provided for feedback from patients as to how the service might be improved. Eighty questionnaires were appropriately completed. Outcomes revealed positive responses in 84% with respect to their experience before attending the clinic, 93% relating to the Ambulatory Gynaecology clinic environment, 96% for communication within the service, 91% for their experience during the procedure and 88% for aftercare information. This study concludes that an ambulatory approach to managing a range of gynaecology referrals is a highly acceptable approach in an Irish gynaecological population. Valuable feedback was gained from the study, which will allow us to further enhance the service for our patients.

Losing work: regional unemployment and its effect on homeless demographic characteristics, needs, and health care

BACKGROUND

Who becomes homeless because of unemployment and what they need are poorly understood.

METHODS

Four-year time-series study. Homeless characteristics, co-morbid conditions, and needs are correlated with unemployment rates.

RESULTS

The unemployment rate averaged 6.7% during years 1-2 (N=198) and 11.8% during years 3-4 (N=202). Those presenting during high unemployment worked most recently in clerical positions (10.4% vs. 4.5%, p= .02) and reported unemployment (OR=2.0; 95% CI; 1.07, 3.76) and unaffordable housing (28.7% vs. 15.2%; p<.01) causing homelessness. Those reporting unemployment were more likely to be local residents (OR=2.1; CI=1.01, 4.53), but less likely to have family support (OR=0.4; CI=0.19, 0.87). While comparable proportions reported mental health conditions and received care, more high unemployment individuals reported needing additional care (59.9% vs. 42.9%; p<.001) and that this was necessary for leaving homelessness (58.9% vs. 44.1%; p=.05).

CONCLUSIONS

High unemployment expands the population vulnerable to homelessness and influences health care needs and social needs.

Neuroimaging findings in sickle cell disease

At least 25% of individuals with sickle cell disease will have a neurological complication over their lifetime, often as early as in childhood. Neuroradiological findings in patients with sickle cell disease are common and include acute territorial infarction, silent ischaemia and intracranial haemorrhage. Imaging abnormalities are typically, but not always, manifestations of the underlying vasculopathy. Coexisting acute and chronic pathology may pose challenges to interpretation.

SPECT-CT: applications in musculoskeletal radiology

This article reviews the technique, basic science principles and applications of integrated single photon emission CT (SPECT)-CT in musculoskeletal radiology. A review of the current evidence on the topic was undertaken, and selected clinical cases from the authors' institution have been used for illustration. SPECT-CT is a technology with emerging applications that offers technical advantages to image fusion of separately acquired SPECT and CT studies. The prevailing evidence indicates that there may be benefit in adding SPECT-CT to conventional imaging algorithms during the evaluation of some malignant and benign musculoskeletal conditions. SPECT-CT can improve both sensitivity and specificity by reducing equivocal interpretation in comparison to planar scintigraphy or SPECT alone. The evidence base for SPECT-CT in musculoskeletal radiology is still evolving. There is a lack of evidence comparing SPECT-CT with MRI in many key indications, and further research is required in these areas.

Creation of a percutaneous mesocaval shunt to control variceal bleeding in a child

Although transjugular intrahepatic portosystemic shunt (TIPS) placement is the standard procedure for the treatment of portal hypertension, it is often impossible to perform in patients with extrahepatic portal vein occlusion. In these patients, options for decompressing the liver are few. In this report, we present a novel solution for managing gastro-esophageal hemorrhage in a child with portal hypertension and extrahepatic portal vein occlusion, through the creation of a percutaneous mesocaval shunt.

Ultrasound-guided core biopsy in the diagnosis of lymphoma of the head and neck. A 9 year experience

OBJECTIVES

This retrospective study aimed to evaluate the diagnostic utility of ultrasound-guided core biopsy (USCB) in lymphoma of the head and neck, in particular whether core biopsy can provide sufficient diagnostic information for definitive treatment.

METHODS

All lymphomas diagnosed in the head and neck at Eastbourne General Hospital between January 2000 and June 2009 were identified. Radiology and pathology reports were reviewed and the diagnostic techniques recorded. The type of biopsy (fine needle aspiration, needle core, surgical excision biopsy) used to establish a diagnosis sufficient to allow treatment, i.e. the "index" diagnostic technique, was identified. Previous inconclusive or inadequate biopsies were noted. Pathology reports based on USCB were graded 0-3 according to diagnostic completeness and ability to provide treatment information.

RESULTS

Of 691 overall cases of lymphoma diagnosed over the 9 year period, 171 different patients presented with lymphoma in the head and neck. Of these 171, 83 had USCB biopsy during diagnostic work up. 60 were regarded as grade 3 where a confident diagnosis of lymphoma was made. In seven patients, clinical management proceeded on the basis of a suggestive (grade 2) pathology report without surgical excision, and these were therefore also included as "index" biopsies. Overall therefore, 67/83 core biopsies (81%) provided adequate information to allow treatment. Surgical excision biopsy was the index modality in 104 cases.

CONCLUSION

In the majority of cases USCB is adequate for confident histopathological diagnosis avoiding the need for surgical excision biopsy in cases of suspected head and neck lymphoma.
