Vascular health years after a hypertensive disorder of pregnancy: The EPOCH study.

BACKGROUND: Preeclampsia is associated with a two-fold increase in a woman's lifetime risk of developing atherosclerotic cardiovascular disease (ASCVD), but the reasons for this association are uncertain. The objective of this study was to examine the associations between vascular health and a hypertensive disorder of pregnancy among women ≥ 2 years postpartum. METHODS: Pre-menopausal women with a history of either a hypertensive disorder of pregnancy (cases: preeclampsia or gestational hypertension) or a normotensive pregnancy (controls) were enrolled. Participants were assessed for standard ASCVD risk factors and underwent vascular testing, including measurements of blood pressure, endothelial function, and carotid artery ultrasound. The primary outcomes were blood pressure, ASCVD risk, reactive hyperemia index measured by EndoPAT and carotid intima-medial thickness. The secondary outcomes were augmentation index normalized to 75 beats per minute and pulse wave amplitude measured by EndoPAT, and carotid elastic modulus and carotid beta-stiffness measured by carotid ultrasound. RESULTS: Participants had a mean age of 40.7 years and were 5.7 years since their last pregnancy. In bivariate analyses, cases (N = 68) were more likely than controls (N = 71) to have hypertension (18% vs 4%, P = .034), higher calculated ASCVD risk (0.6 vs 0.4, P = .02), higher blood pressures (systolic: 118.5 vs 111.6 mm Hg, P = .0004; diastolic: 75.2 vs 69.8 mm Hg, P = .0004), and higher augmentation index values (7.7 vs 2.3, P = .03). They did not, however, differ significantly in carotid intima-media thickness (0.5 vs 0.5, P = .29) or reactive hyperemia index (2.1 vs 2.1, P = .93), nor in pulse wave amplitude (416 vs 326, P = .11), carotid elastic modulus (445 vs 426, P = .36), or carotid beta stiffness (2.8 vs 2.8, P = .86). CONCLUSION: Women with a prior hypertensive disorder of pregnancy had higher ASCVD risk and blood pressures several years postpartum, but did not have more endothelial dysfunction or subclinical atherosclerosis.

Mental health conditions and contraception: current landscape, reproductive health and obstetric outcomes, and clinical guidance.

PURPOSE OF REVIEW: This review presents the epidemiology of mental health conditions among reproductive aged people, common adverse reproductive outcomes, the hormonal profile of contraception and its relationship with psychiatric outcomes, and updated information for clinicians providing contraceptive counselling for this population. RECENT FINDINGS: There is variability among contraceptive behaviours and patterns across those who have mental health conditions, impacting reproductive, psychiatric, and perinatal outcomes. The endocrinology of hormonal contraceptives is well understood, however, the impacts of steroidal hormones on mental health outcomes continue to be less understood. Overall, hormonal contraceptives are safe to use among those with mental health conditions, and among those using selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors. Additional considerations are needed when prescribing contraception among people who may be at risk of poor adherence, who use certain classes of antidepressants, antipsychotics, antiepileptics, and who are <6 weeks postpartum. SUMMARY: Barriers to effective contraceptive use should be addressed and myths on negative psychiatric impacts of hormonal contraceptives should be dispelled. Healthcare clinicians should seek out opportunities to become proficient in contraception counselling to improve health outcomes among people with mental health conditions.

Associations between anxiety, sleep, and blood pressure parameters in pregnancy: a prospective pilot cohort study.

BACKGROUND: The potential effect modification of sleep on the relationship between anxiety and elevated blood pressure (BP) in pregnancy is understudied. We evaluated the relationship between anxiety, insomnia, and short sleep duration, as well as any interaction effects between these variables, on BP during pregnancy. METHODS: This was a prospective pilot cohort of pregnant people between 23 to 36 weeks' gestation at a single institution between 2021 and 2022. Standardized questionnaires were used to measure clinical insomnia and anxiety. Objective sleep duration was measured using a wrist-worn actigraphy device. Primary outcomes were systolic (SBP), diastolic (DBP), and mean (MAP) non-invasive BP measurements. Separate sequential multivariable linear regression models fit with generalized estimating equations (GEE) were used to separately assess associations between anxiety (independent variable) and each BP parameter (dependent variables), after adjusting for potential confounders (Model 1). Additional analyses were conducted adding insomnia and the interaction between anxiety and insomnia as independent variables (Model 2), and adding short sleep duration and the interaction between anxiety and short sleep duration as independent variables (Model 3), to evaluate any moderating effects on BP parameters. RESULTS: Among the 60 participants who completed the study, 15 (25%) screened positive for anxiety, 11 (18%) had subjective insomnia, and 34 (59%) had objective short sleep duration. In Model 1, increased anxiety was not associated with increases in any BP parameters. When subjective insomnia was included in Model 2, increased DBP and MAP was significantly associated with anxiety (DBP: ß 6.1, p = 0.01, MAP: ß 6.2 p < 0.01). When short sleep was included in Model 3, all BP parameters were significantly associated with anxiety (SBP: ß 9.6, p = 0.01, DBP: ß 8.1, p < 0.001, and MAP: ß 8.8, p < 0.001). No moderating effects were detected between insomnia and anxiety (p interactions: SBP 0.80, DBP 0.60, MAP 0.32) or between short sleep duration and anxiety (p interactions: SBP 0.12, DBP 0.24, MAP 0.13) on BP. CONCLUSIONS: When including either subjective insomnia or objective short sleep duration, pregnant people with anxiety had 5.1-9.6 mmHg higher SBP, 6.1-8.1 mmHg higher DBP, and 6.2-8.8 mmHg higher MAP than people without anxiety.

Uterine atony.

PURPOSE OF REVIEW: Postpartum hemorrhage (PPH) is the leading preventable cause of maternal morbidity and mortality worldwide. Uterine atony is identified as the underlying etiology in up to 80% of PPH. This serves as a contemporary review of the epidemiology, risk factors, pathophysiology, and treatment of uterine atony. RECENT FINDINGS: Rates of postpartum hemorrhage continue to rise worldwide with the largest fraction attributed to uterine atony. A simple 0-10 numerical rating score for uterine tone was recently validated for use during cesarean delivery and may allow for more standardized assessment in clinical and research settings. The optimal prophylactic dose of oxytocin differs depending on the patient population, but less than 5 units and as low as a fraction of one unit is needed for PPH prevention, with an increased requirements within that range for cesarean birth, those on magnesium, and advanced maternal age. Carbetocin is an appropriate alternative to oxytocin. Misoprostol shows limited to no efficacy for uterine atony in recent studies. Several uncontrolled case studies demonstrate novel mechanical and surgical interventions for treating uterine atony. SUMMARY: There is a critical, unmet need for contemporary, controlled studies to address the increasing threat of atonic PPH.

Optimizing postpartum contraception for high-risk obstetric patients.

PURPOSE OF REVIEW: This review will focus on those who are at greatest risk of maternal and neonatal morbidity from a subsequent unplanned or short interval pregnancy and the interventions to increase contraceptive uptake in the postpartum period. RECENT FINDINGS: Populations at highest risk of maternal or neonatal morbidity - those with a history of preterm birth or those with complex medical conditions - are also those at the highest risk for unintended pregnancies attributed to low-efficacy contraceptive failure/ noncontraceptive use, and many are discharged from birth hospitalization without understanding the importance of birth spacing related to their high-risk pregnancies. Current innovative strategies to improve postpartum contraception access and uptake among high-risk populations include utilizing the antenatal period to initiate contraception counseling, developing multidisciplinary teams, and incorporating multimedia-based educational tools. However, ongoing challenges that continue to pose barriers to contraception access include racial and economic disparities and the restructuring of obstetric care during the COVID-19 pandemic. SUMMARY: Preventing an unintended short interval pregnancy by providing contraception in the postpartum period is one of the most modifiable risk factors for those at highest risk of subsequent maternal or neonatal morbidity and therefore should be prioritized by clinicians, hospitals, and insurance coverage.

Elusive Neck Carcinoma Simulating Idiopathic Intracranial Hypertension Due to Jugular Venous Outflow Obstruction - Case Report.

Few cases have been reported of extra-cranial tumours in the neck causing intracranial hypertension due to jugular vein compression and consequent outflow obstruction. We present a case of a patient presenting with transient vision loss due to intracranial hypertension of unidentifiable cause on initial imaging workup. Upon further evaluation, the patient was found to have a neck tumour compressing the right jugular vein with stenosis of the ipsilateral transverse sinus - both contributing to his intracranial hypertension. Atypical patients presenting with symptoms concerning for intracranial hypertension may benefit from imaging below the level of the head to evaluate for extra-cranial causes.

Implementation effectiveness of psychosocial and environmental care practices in assisted living.

Psychosocial and environmental care practices are recommended to address behavioral expressions in persons with dementia, but their use has been limited partly because guidance is lacking regarding implementation. In response, we developed a simple "how-to" guide of evidence-based protocols for aromatherapy, natural light, familiar music, and robotic pets; trained staff in four assisted living (AL) communities to use the practices; provided materials; met with them regularly; and evaluated fidelity, facilitators and barriers to implementation, and staff knowledge, attitudes, and self-efficacy. After two months, staff reported more familiarity, confidence, and use; barriers such as difficulty locating supplies and task-focused staff with limited time; and staff "champion" facilitators. Notable differences were identified across communities, suggesting that just as care to individuals must be person-centered, practices embraced by communities must fit that community. Through strategic adoption, successful implementation is possible. The "how-to" guide is appropriate for AL, nursing homes, and persons' own homes.

Extended live-tracking and quantitative characterization of wound healing and cell migration with SiR-Hoechst.

Cell migration is essential to many life processes, including immune response, tissue repair, and cancer progression. A reliable quantitative characterization of the cell migration can therefore aid in the high throughput screening of drug efficacy in wound healing and cancer treatments. In this work, we report what we believe is the first use of SiR-Hoechst for extended live tracking and automated analysis of cell migration and wound healing. We showed through rigorous statistical comparisons that this far-red label does not affect migratory behavior. We observed excellent automated tracking of random cell migration, in which the motility parameters (speed, displacement, path length, directionality ratio, persistence time, and direction autocorrelation) obtained closely match those obtained from manual tracking. We also present an analysis framework to characterize the healing of a scratch wound from the perspective of single cells. The use of SiR-Hoechst is advantageous for the crowded environments in wound healing assays because as long as cell nuclei do not overlap, continuous tracking can be maintained even if there is cell-cell contact. In this paper, we report wound recovery based on the number of cells migrating into the wound over time, normalized by the initial cell count prior to the infliction of the wound. This normalized cell count approach is impervious to operator bias during the arbitration of wound edges and is also robust against variability that arises due to differences in the cell density of different samples. Additional wound healing characteristics were also defined based on the evolution of cell speed and directionality during healing. Not unexpected, the wound healing cells exhibited much higher tendency to maintain the same migratory direction in comparison to the randomly migrating cells. The use of SiR-Hoechst thus greatly simplified the automation of single cell and whole population analysis with high spatial and temporal resolution over extended periods of time.

Expression of α-subunit of α-glucosidase II in adult mouse brain regions and selected organs.

α-Glucosidase II (GII), a resident of endoplasmic reticulum (ER) and an important enzyme in the folding of nascent glycoproteins, is heterodimeric, consisting of α (GIIα) and ß (GIIß) subunits. The catalytic GIIα subunit, with the help of mannose 6-phosphate receptor homology domain of GIIß, sequentially hydrolyzes two α1-3-linked glucose residues in the second step of N-linked oligosaccharide-mediated protein folding. The soluble GIIα subunit is retained in the ER through its interaction with the HDEL-containing GIIß subunit. N-glycosylation and correct protein folding are crucial for protein stability and trafficking and cell surface expression of several proteins in the brain. Alterations in N-glycosylation lead to abnormalities in neuronal migration and mental retardation, various neurodegenerative diseases, and invasion of malignant gliomas. Inhibitors of GII are used to inhibit cell proliferation and migration in a variety of different pathologies, such as viral infection, cancer, and diabetes. Despite the widespread use of GIIα inhibitory drugs and the role of GIIα in brain function, little is known about its expression in brain and other tissues. Here, we report generation of a highly specific chicken antibody to the GIIα subunit and its characterization by Western blotting and immunoprecipitation using cerebral cortical extracts. By using this antibody, we showed that the GIIα protein is highly expressed in testis, kidney, and lung, with the lowest amount in heart. GIIα polypeptide levels in whole brain were comparable to those in spleen. However, a higher expression of GIIα protein was detected in the cerebral cortex, reflecting its continuous requirement in correct folding of cell surface proteins.

Dehydration in the Older Adult.

Dehydration affects 20% to 30% of older adults. It has a greater negative outcome in this population than in younger adults and increases mortality, morbidity, and disability. Dehydration is often caused by water deprivation in older adults, although excess water loss may also be a cause. Traditional markers for dehydration do not take into consideration many of the physiological differences present in older adults. Clinical assessment of dehydration in older adults poses different findings, yet is not always diagnostic. Treatment of dehydration should focus on prevention and early diagnosis before it negatively effects health and gives rise to comorbidities. The current article discusses what has most thoroughly been studied; the best strategies and assessment tools for evaluation, diagnosis, and treatment of dehydration in older adults; and what needs to be researched further.

Mifepristone and misoprostol in California pharmacies after modifications to the Risk Evaluation and Mitigation Strategy Program.

In January 2023, the Food & Drug Administration modified the Risk Evaluation and Mitigation Strategy program regulating mifepristone to allow direct dispensation from retail pharmacies. In June 2023, we conducted a random, distributive survey of pharmacies in California using secret shopper methodology to investigate the feasibility of accessing mifepristone. One pharmacy had mifepristone immediately available (<24 hours), and misoprostol availability was limited. Accessibility to misoprostol varied by type of pharmacy (p < 0.01), but not by region. Even in a reproductive freedom state, access to mifepristone and misoprostol from outpatient retail pharmacies remains limited.

A Case of an Obstructed Delivery by a Large, Lower Uterine Segment Fibroid Interlocked with a Fetal Mentum.

Uterine leiomyomata are associated with many pregnancy complications and will likely become increasingly common as the average age of childbearing increases. We describe a case of an obstructed delivery by a large fibroid. A 37-year-old G2P1001 with a 10-cm anterior, lower uterine segment fibroid presented for labor induction. Labor was complicated by arrest of descent due to suspected obstruction of the fetal body by the fibroid after descent of the fetal head, and delivery during cesarean section was complicated by apparent interlocking of the fetal mentum with the fibroid. Large, anterior lower uterine segment fibroids have the potential to obstruct delivery of the fetal head or of the fetal body, and these patients should be counseled regarding the potential for complications via both vaginal and cesarean deliveries.

Racial and Ethnic Disparities in Cervical Insufficiency, Cervical Cerclage, and Preterm Birth.

Background: The frequency of cervical insufficiency differs among the major racial and ethnic groups, with limited data specific to Asian American and Native Hawaiian/Pacific Islander (AANHPI) subpopulations. We assessed cervical insufficiency diagnoses and related outcomes across 10 racial and ethnic groups, including disaggregated AANHPI subgroups, in a large population-based cohort. Study Design: We performed a retrospective cohort study of all singleton births between 20-42 weeks' gestation in California from 2007 to 2018. Logistic regression models were performed to estimate the odds of cervical insufficiency and, among people with cervical insufficiency, the odds of cerclage and preterm birth according to self-reported race and ethnicity. Results: Among 5,114,470 births, 38,605 (0.8%) had a diagnosis code for cervical insufficiency. Compared with non-Hispanic White people, non-Hispanic Black people had the highest odds of cervical insufficiency (adjusted odds ratio [aOR] 3.07; 95% confidence interval [CI], 2.97, 3.18), for cerclage placement and higher odds for preterm birth. Disaggregating AANHPI subgroups showed that Indian people had the highest odds (aOR 1.94; 95% CI, 1.82, 2.07) of cervical insufficiency and had significantly higher odds of cerclage without increased odds of preterm birth; Southeast Asian people had the highest odds of preterm birth. Conclusion: Within a large, diverse population-based cohort, non-Hispanic Black people experienced the highest rates of cervical insufficiency, and among those with cervical insufficiency, had among the highest rates of cerclage and preterm birth. Among AANHPI subgroups specifically, Indian people had the highest rates of cervical insufficiency and cerclage placement, without increased rates of preterm birth; Southeast Asian people had the highest rates of preterm birth, without increased rates of cerclage. Disaggregating AANHPI subgroups identifies important differences in obstetric risk factors and outcomes.

Evaluation of Sleep in Pregnant Inpatients Compared With Outpatients.

OBJECTIVE: To evaluate whether antepartum hospitalization was associated with differences in sleep duration or disrupted sleep patterns. METHODS: This was a prospective cohort study with enrollment of pregnant people aged 18-55 years with singleton gestations at 16 weeks of gestation or more between 2021 and 2022. Each enrolled antepartum patient was matched by gestational age to outpatients recruited from obstetric clinics at the same institution. Participants responded to the ISI (Insomnia Severity Index) and wore actigraph accelerometer watches for up to 7 days. The primary outcome was total sleep duration per 24 hours. Secondary outcomes included sleep efficiency (time asleep/time in bed), ISI score, clinical insomnia (ISI score higher than 15), short sleep duration (less than 300 minutes/24 hours), wakefulness after sleep onset, number of awakenings, and sleep fragmentation index. Outcomes were evaluated with multivariable generalized estimating equations adjusted for body mass index (BMI), sleep aid use, and insurance type, accounting for gestational age correlations. An interaction term assessed the joint effects of time and inpatient status. RESULTS: Overall 58 participants were included: 18 inpatients and 40 outpatients. Inpatients had significantly lower total sleep duration than outpatients (mean 4.4 hours [SD 1.6 hours] inpatient vs 5.2 hours [SD 1.5 hours] outpatient, adjusted ß=-1.1, 95% CI, -1.8 to -0.3, P =.01). Awakenings (10.1 inpatient vs 13.8, P =.01) and wakefulness after sleep onset (28.3 inpatient vs 35.5 outpatient, P =.03) were lower among inpatients. There were no differences in the other sleep outcomes, and no interaction was detected for time in the study and inpatient status. Inpatients were more likely to use sleep aids (39.9% vs 12.5%, P =.03). CONCLUSION: Hospitalized pregnant patients slept about 1 hour/day less than outpatients. Fewer awakenings and reduced wakefulness after sleep onset among inpatients may reflect increased use of sleep aids in hospitalized patients.

Physical activity among pregnant inpatients and outpatients and associations with anxiety.

OBJECTIVE: Physical activity is linked to lower anxiety, but little is known about the association during pregnancy. This is especially important for antepartum inpatients, who are known to have increased anxiety yet may not be able to achieve target levels of physical activity during hospitalization. We compared physical activity metrics between pregnant inpatients and outpatients and explored correlations with anxiety. MATERIALS AND METHODS: This was a prospective cohort between 2021 and 2022 of pregnant people aged 18-55 years carrying singleton gestations ≥ 16 weeks. Three exposure groups were matched for gestational age: 1) outpatients from general obstetric clinics; 2) outpatients from high-risk Maternal-Fetal Medicine obstetric clinics; and 3) antepartum inpatients. Participants wore Actigraph GT9X Link accelerometer watches for up to 7 days to measure physical activity. The primary outcome was mean daily step count. Secondary outcomes were metabolic equivalent tasks (METs), hourly kilocalories (kcals), moderate to vigorous physical activity (MVPA) bursts, and anxiety (State-Trait Anxiety Inventory [STAI]). Step counts were compared using multivariable generalized estimating equations adjusting for maternal age, body-mass index, and insurance type as a socioeconomic construct, accounting for within-group clustering by gestational age. Spearman correlations were used to correlate anxiety scores with step counts. RESULTS: 58 participants were analyzed. Compared to outpatients, inpatients had significantly lower mean daily steps (primary outcome, adjusted beta -2185, 95 % confidence interval [CI] -3146, -1224, p < 0.01), METs (adjusted beta -0.18, 95 % CI -0.23, -0.13, p < 0.01), MVPAs (adjusted beta -38.2, 95 % CI -52.3, -24.1, p < 0.01), and kcals (adjusted beta -222.9, 95 % CI -438.0, -7.8, p = 0.04). Over the course of the week, steps progressively decreased for inpatients (p-interaction 0.01) but not for either of the outpatient groups. Among the entire cohort, lower step counts correlated with higher anxiety scores (r = 0.30, p = 0.02). CONCLUSION: We present antenatal population norms and variance for step counts, metabolic equivalent tasks, moderate to vigorous physical activity bursts, and kcals, as well as correlations with anxiety. Antepartum inpatients had significantly lower physical activity than outpatients, and lower step counts correlated with higher anxiety levels. These results highlight the need for physical activity interventions, particularly for hospitalized pregnant people.

Prior Cesarean Birth and Risk of Uterine Rupture in Second-Trimester Medication Abortions Using Mifepristone and Misoprostol: A Systematic Review and Meta-analysis.

OBJECTIVE: To assess the risk difference of uterine rupture when using current mifepristone and misoprostol regimens for second-trimester abortion among individuals with prior cesarean birth compared with those without prior cesarean birth. DATA SOURCES: We searched the terms second trimester, induction, mifepristone, and abortion in PubMed, EMBASE, POPLINE, ClinicalTrials.gov , and Cochrane Library from inception until December 2022. METHODS OF STUDY SELECTION: We included randomized trials and observational studies including a mixed cohort, with and without uterine scar, of individuals at 14-28 weeks of gestation who used mifepristone and misoprostol to end a pregnancy or to manage a fetal death. We excluded case reports, narrative reviews, and studies not published in English. Two reviewers independently screened studies. TABULATION, INTEGRATION, AND RESULTS: Absolute risks with binomial CIs were calculated from pooled data. Using R software, we estimated total risk difference by the Mantel-Haenszel random-effects method without continuity correction. For studies with zero events, a continuity correction of 0.5 was applied for individual risk differences and plotted graphically with forest plots. Statistical heterogeneity was assessed with Higgins I2 statistics. Funnel plot assessed for publication bias. Of 198 articles identified, 22 met the inclusion criteria: seven randomized trials (n=923) and 15 observational studies (n=6,195). Uterine rupture risk with prior cesarean birth was 1.1% (10/874) (95% CI 0.6-2.1) and without prior cesarean birth was 0.01% (2/6,244) (95% CI 0.0-0.12). The risk difference was 1.23% (95% CI 0.46-2.00, I2 =0%). Of the 12 reported uterine ruptures, three resulted in hysterectomy. CONCLUSION: Uterine rupture with mifepristone and misoprostol use during second-trimester induction abortion is rare, with the risk increased to 1% in individuals with prior cesarean birth.

Abortion Bans and Resource Utilization for Congenital Heart Disease: A Decision Analysis.

OBJECTIVE: To investigate the implications of potential national abortion ban scenarios on the incidence of neonatal single-ventricle cardiac defects. METHODS: A decision tree model was developed to predict the incidence of neonatal single-ventricle cardiac defects and related outcomes in the United States under four theoretical national abortion bans: 1) abortion restrictions in existence immediately before the June 2022 Dobbs v Jackson Women's Health Organization Supreme Court decision, 2) 20 weeks of gestation, 3) 13 weeks of gestation, and 4) a complete abortion ban. The model included incidence of live births of neonates with single-ventricle cardiac defects, neonatal heart surgery (including heart transplant and extracorporeal membrane oxygenation [ECMO]), and neonatal death. Cohort size was based on national pregnancy incidence and different algorithm decision point probabilities were aggregated from the existing literature. Monte Carlo simulations were conducted with 10,000 iterations per model. RESULTS: In the scenario before the Dobbs decision, an estimated 6,369,000 annual pregnancies in the United States resulted in 1,006 annual cases of single-ventricle cardiac defects. Under a complete abortion ban, the model predicted a 53.7% increase in single-ventricle cardiac defects, or an additional 9 cases per 100,000 live births. This increase would result in an additional 531 neonatal heart surgeries, 16 heart transplants, 77 ECMO utilizations, and 102 neonatal deaths annually. More restrictive gestational age-based bans are predicted to confer increases in cases of neonatal single-ventricle cardiac defects and related adverse outcomes as well. CONCLUSION: Universal abortion bans are estimated to increase the incidence of neonatal single-ventricle cardiac defects, associated morbidity, and resource utilization. States considering limiting abortion should consider the implications on the resources required to care for increasing number of children that will be born with significant and complex medical needs, including those with congenital heart disease.

Recruitment approaches and profiles of consenting family caregivers and people living with dementia: A recruitment study within a trial.

Background: While studies have identified strategies that are useful for recruiting people living with dementia, none have focused on psychosocial interventions involving arts therapies, or have examined the profiles of older people living in the community who consent or decline participation, particularly during a global pandemic. We aimed to identify the most effective recruitment strategies according to participant characteristics and transnational differences and develop a profile of consenting and non-consenting participants. Methods: Recruitment teams in Australia, Norway, Germany, Poland, and the United Kingdom, recorded participants' source of study awareness and characteristics of consenting and non-consenting participants. Distributions of participants 'consenting to participate' were compared and logistic regressions were used to estimate the odds ratios. Results: Consenting female caregivers were disproportionally represented. Study awareness differed between countries but overall, most expressions of interest to participate were derived from referrals from professionals or organisations, or from databases of people wanting to participate in research. Troughs in recruitment rates occurred during Northern Hemisphere summer vacation periods, and during Christmas periods. Conclusions: This study found that recruiting for a trial with community-dwelling family caregivers and people living with dementia is challenging, especially during a global pandemic. While spousal caregivers comprised the highest proportion of dyads recruited, overall spousal caregivers were more reluctant to consent to participate than adult child caregivers. More targeted recruitment strategies designed for minority groups are also needed to ensure broader representation in dementia treatment studies.

Home-based family caregiver-delivered music and reading interventions for people living with dementia (HOMESIDE trial): an international randomised controlled trial.

Background: Music interventions provided by qualified therapists within residential aged care are effective at attenuating behavioural and psychological symptoms (BPSD) of people with dementia (PwD). The impact of music interventions on dementia symptom management when provided by family caregivers is unclear. Methods: We implemented a community-based, large, pragmatic, international, superiority, single-masked randomised controlled trial to evaluate if caregiver-delivered music was superior to usual care alone (UC) on reducing BPSD of PwD measured by the Neuropsychiatric Inventory-Questionnaire (NPI-Q). The study included an active control (reading). People with dementia (NPI-Q score ≥6) and their caregiver (dyads) from one of five countries were randomly allocated to caregiver-delivered music, reading, or UC with a 1:1:1 allocation stratified by site. Caregivers received three online protocolised music or reading training sessions delivered by therapists and were recommended to provide five 30-min reading or music activities per week (minimum twice weekly) over 90-days. The NPI-Q severity assessment of PwD was completed online by masked assessors at baseline, 90- (primary) and 180-days post-randomisation and analysed on an intention-to-treat basis using a likelihood-based longitudinal data analysis model. ACTRN12618001799246; ClinicalTrials.govNCT03907748. Findings: Between 27th November 2019 and 7th July 2022, we randomised 432 eligible of 805 screened dyads (music n = 143, reading n = 144, UC n = 145). There was no statistical or clinically important difference in the change from baseline BPSD between caregiver-delivered music (-0.15, 95% CI -1.41 to 1.10, p = 0.81) or reading (-1.12, 95% CI -2.38 to 0.14, p = 0.082) and UC alone at 90-days. No related adverse events occurred. Interpretation: Our findings suggested that music interventions and reading interventions delivered by trained caregivers in community contexts do not decrease enduring BPSD symptoms. Funding: Our funding was provided by National Health and Medical Research Council, Australia; The Research Council of Norway; Federal Ministry of Education and Research, Germany; National Centre for Research and Development, Poland; Alzheimer's Society, UK, as part of the Joint Programme for Neurodegenerative Diseases consortia scheme.

Gender-based salary differences in academic medicine: a retrospective review of data from six public medical centers in the Western USA.

OBJECTIVES: We assessed the effect of gender, rank and research productivity on compensation for faculty at academic medical centres. DESIGN: A web-based retrospective review of salary for professors in 2016. SETTING: Faculty from six state-run, publicly funded academic medical centres in the Western USA. PARTICIPANTS: 799 faculty members, 225 assistant (51% women), 200 associate (40% women) and 374 full professors (32% women) from general surgery (26% women), obstetrics and gynaecology (70% women) and radiology (34% women). METHODS: Archived online faculty profiles were reviewed for gender, rank and compensation (total, baseline and supplemental). Total compensation was defined as baseline compensation plus supplemental income. Baseline compensation was defined as base salary minus reductions due to participation in the voluntary Employee Reduction in Time and phased retirement programmes. Supplemental income was defined as additional salary for clinical care and research (eg, grants). Elsevier's Scopus was used to collect data on h-index, a measure of research productivity. Linear regression models were estimated to determine the relationship between these factors and salary. RESULTS: Total compensation was significantly higher for men across all professorial ranks in both general surgery [Formula: see text] and obstetrics and gynaecology [Formula: see text]. Women faculty members within these departments earned almost US$75 000 less than their men colleagues. The disparity in salary originates from gaps in supplemental income, as baseline compensation was not significantly different between men and women. No significant gender difference in total compensation for radiology was found [Formula: see text]. Higher h-index was associated with higher baseline compensation across all departments as well as with supplemental income for general surgery. Higher h-index was related to lower supplemental income for radiology and was not related to supplemental income for obstetrics and gynaecology. CONCLUSIONS: Further investigations should focus on discrepancies in supplemental income, which may preferentially benefit men.
