mHealth-Based Just-in-Time Adaptive Intervention to Improve the Physical Activity Levels of Individuals With Spinal Cord Injury: Protocol for a Randomized Controlled Trial.
BACKGROUND
The lack of regular physical activity (PA) in individuals with spinal cord injury (SCI) in the United States is an ongoing health crisis. Regular PA and exercise-based interventions have been linked with improved outcomes and healthier lifestyles among those with SCI. Providing people with an accurate estimate of their everyday PA level can promote PA. Furthermore, PA tracking can be combined with mobile health technology such as smartphones and smartwatches to provide a just-in-time adaptive intervention (JITAI) for individuals with SCI as they go about everyday life. A JITAI can prompt an individual to set a PA goal or provide feedback about their PA levels.
OBJECTIVE
The primary aim of this study is to investigate whether minutes of moderate-intensity PA among individuals with SCI can be increased by integrating a JITAI with a web-based PA intervention (WI) program. The WI program is a 14-week web-based PA program widely recommended for individuals with disabilities. A secondary aim is to investigate the benefit of a JITAI on proximal PA, defined as minutes of moderate-intensity PA within 120 minutes of a PA feedback prompt.
METHODS
Individuals with SCI (N=196) will be randomized to a WI arm or a WI+JITAI arm. Within the WI+JITAI arm, a microrandomized trial will be used to randomize participants several times a day to different tailored feedback and PA recommendations. Participants will take part in the 24-week study from their home environment in the community. The study has three phases: (1) baseline, (2) WI program with or without JITAI, and (3) PA sustainability. Participants will provide survey-based information at the initial meeting and at the end of weeks 2, 8, 16, and 24. Participants will be asked to wear a smartwatch every day for ≥12 hours for the duration of the study.
RESULTS
Recruitment and enrollment began in May 2023. Data analysis is expected to be completed within 6 months of finishing participant data collection.
CONCLUSIONS
The JITAI has the potential to achieve long-term PA performance by delivering tailored, just-in-time feedback based on the person's actual PA behavior rather than a generic PA recommendation. New insights from this study may guide intervention designers to develop engaging PA interventions for individuals with disability.

SARS-CoV-2 induces delayed type-I/III interferon production, allowing it to escape the early innate immune response. The delay has been attributed to a deficiency in the ability of cells to sense viral replication upon infection, which in turn hampers activation of the antiviral state in bystander cells. Here, we introduce a cellular automaton model to investigate the spatiotemporal spreading of viral infection as a function of virus and host-dependent parameters. The model suggests that the considerable person-to-person heterogeneity in SARS-CoV-2 infections is a consequence of high sensitivity to slight variations in biological parameters near a critical threshold. It further suggests that within-host viral proliferation can be curtailed by the presence of remarkably few cells that are primed for IFN production. Thus, the observed heterogeneity in defense readiness of cells reflects a remarkably cost-efficient strategy for protection.

Unit cohesion is the extent to which military service members feel committed to and supported by their military unit or, conversely, feel overlooked, neglected, and/or alienated. Unit cohesion reflects an important aspect of military social support and can act as a protective factor against mental health challenges, particularly in challenging situations. Theoretical suppositions and emerging evidence suggest that different types of unit support, specifically, and , uniquely matter for service member well-being. (support from leaders in the unit and other higher-ranking positions) may be of universal importance to service members with implications for career progression and personal wellbeing, while (support from fellow unit members and peers) may be of importance under certain circumstances. Informed by the psychometric theory of scale development and validation, the dimensionality of unit cohesion theory, and the need for brief, sound measurement tools, this study first examined the psychometric properties of the Army STARRS four-item Vertical Unit Cohesion Scale in a longitudinal analysis with a large, diverse sample of Soldiers from the Pre/Post Deployment Study component of the Army STARRS dataset ( = 10,116). Then, exploratory analyses were conducted to examine the properties of the Horizontal Unit Cohesion Scale and understand the relationship between vertical and horizontal unit cohesion. Strong evidence for the Vertical Unit Cohesion Scale's psychometric soundness was established regarding factor structure, measurement invariance overtime, and construct validity. Conversely, preliminary evidence suggests that the three-item measure of Horizontal Unit Cohesion should be used with caution. Implications for researchers and military leadership are provided.

Effectiveness of non-pharmacological interventions delivered at home for urinary and faecal incontinence with homebound older people: systematic review of randomised controlled trials.
INTRODUCTION
Incontinence is a common, distressing condition, most prevalent in older people. There is an unmet need for effective interventions to support continence. This review focuses on non-pharmacological interventions to reduce incontinence among homebound older people. Aim: to identify interventions with potential to be delivered by care workers, nurses or family members in a person's home.
METHODS
Multiple databases were searched until 15 September 2023 for randomised controlled trials reporting home-based interventions for incontinence for older people (≥65 years) living at home. Two reviewers independently screened titles, abstracts and papers against inclusion criteria, then assessed for the Risk of Bias (RoB2). A third reviewer resolved the discrepancies. Primary data were extracted and synthesised.
RESULTS
A full-text review of 81 papers identified seven eligible papers (1996-2022, all USA), including n = 636 participants (561 women and 75 men). Two studies focusing on multicomponent behavioural interventions showed benefit, as did one study of transcutaneous tibial nerve stimulation self-administered through electrode-embedded socks. Three, which included cognitively impaired people, reported improvement with toileting assistance programmes, but the effects were not all significant. Results were inconclusive from a study examining the effects of fluid intake adjustments. Interventions were delivered by nurses, three in collaboration with family caregivers. No faecal incontinence interventions met the criteria.
CONCLUSION
There is scant evidence for continence supporting interventions delivered in older people's own homes. With an ageing population often reliant on family or social care workers well-placed to support continence promotion and policy drives for services to support older people remaining at home, this evidence gap needs addressing.

BACKGROUND
Dementia caregiving is a dynamic and multidimensional process. To gain a comprehensive understanding of informal caregiving for people living with dementia (PLWD), it is pivotal to assess the quality of life (QoL) of informal caregivers.
OBJECTIVE
To evaluate whether the care-recipient relationship type predicts changes in the QoL of informal caregivers of PLWD over a two-year period.
METHODS
This was a secondary analysis of longitudinal data. The data were drawn from two waves of linked data from the National Health and Aging Trends Study (NHATS) and the National Study of Caregiving (NSOC) (2015: NHATS R5 & NSOC II; 2017: NHATS R7 & NSOC III). Caregivers were categorized into spousal, adult-child, "other" caregiver and "multiple" caregivers. QoL was assessed through negative emotional burden (NEB), positive emotional benefits and social strain (SS). Generalized estimating equation modelling was used to examine changes in caregivers' QoL outcomes across types of relationship over time.
RESULTS
About, 882 caregivers were included who linked to 601 PLWD. After adjusting caregivers' socio-demographics, "other" caregivers had lower risk of NEB and SS than spousal caregivers (OR = 0.34, P = 0.003, 95%CI [0.17, 0.70]; OR = 0.37, P = 0.019, 95%CI 0.16, 0.85], respectively), and PLWD's dementia status would not change these significance (OR = 0.33, P = 0.003, 95%CI [0.16, 0.68]; OR = 0.31, P = 0.005, 95%CI [0.14, 0.71], respectively).
CONCLUSIONS
The study demonstrates that spousal caregivers face a higher risk of NEB and SS over time, underscoring the pressing need to offer accessible and effective support for informal caregivers of PLWD, especially those caring for their spouses.

BACKGROUND
Interventions to foster resilience may promote mental health recovery after exposure to stressors. However, comprehensive systematic syntheses of such evidence in family members of pediatric cancer patients are lacking.
OBJECTIVE
To systematically review and meta-analyze the evidence for the effects of psychological interventions at fostering resilience in family members of pediatric cancer patients.
METHODS
PubMed, Cumulative Index to Nursing and Allied Health Literature, and 9 other databases were searched for articles published until March 2023. Empirical studies on psychological interventions to improve resilience in family members of pediatric cancer patients were included. Full-text and quality appraisals were performed independently by 2 reviewers. Pooled effect sizes were calculated using random-effects meta-analyses.
RESULTS
Seventeen studies were included, of which 10 were included in the meta-analyses. There was a positive effect of interventions on resilience at postintervention time points, but no effects on depressive symptoms, stress, or well-being. The improvement in resilience was sustained in the short term (≤3 months) and medium term (>3 to ≤6 months), with delayed effects on depressive symptoms and stress. In the 6 studies that reported moderate effect sizes, the interventions comprised problem-solving skills, cognitive strategies, promotion of personal strength, and social resources.
CONCLUSION
The findings indicated that psychological interventions targeting resilience have the potential to positively affect the resilience and mental health outcomes of family members, particularly parents.
IMPLICATIONS FOR PRACTICE
Psychological interventions targeting resilience hold promise in improving the mental health of family members. Future interventions should clearly specify the characteristics of the intervention, such as mode of delivery, format, and duration.

JAMA Network Open Jun 2024Unintended pregnancy is a major health risk for adolescents in the US, and adolescents face many barriers to obtaining effective and reliable contraception.
IMPORTANCE
Unintended pregnancy is a major health risk for adolescents in the US, and adolescents face many barriers to obtaining effective and reliable contraception.
OBJECTIVE
To measure and describe the use of contraception, pregnancy risk index (PRI), and emergency contraception (EC) prescriptions among female adolescents accessing the emergency department (ED) for care.
DESIGN, SETTING, AND PARTICIPANTS
This cross-sectional study is a planned secondary analysis of a multicenter trial from April 2021 through April 2022 that used a tablet-based, content-validated, confidential sexual health survey at 6 urban, pediatric tertiary care EDs affiliated with the Pediatric Emergency Care Applied Research Network. Participants were individuals aged 15 to 21 years presenting to the ED who completed the confidential sexual health survey and indicated female sex assigned at birth and prior penile-vaginal sexual intercourse. Data analysis was performed from January 2023 to February 2024.
MAIN OUTCOMES AND MEASURES
The primary outcomes were the type and proportion of contraception use, the PRI, and provision of EC. Separate multivariable logistic regression models were performed to identify sociodemographic factors associated with these outcomes.
RESULTS
A total of 1063 participants (median [IQR] age, 17.5 [16.5-18.3] years) were included in this analysis; 219 (20.8%) identified as Hispanic, 464 (44.1%) identified as non-Hispanic Black, 308 (29.3%) identified as non-Hispanic White, and 61 (5.8%) identified as other races and ethnicities. In total, 756 participants (71.1%) reported contraception use during their last sexual encounter. Long-acting reversible contraception use (LARC) was the least used (164 participants [15.4%]), and 307 (28.9%) reported no contraception use. Sociodemographic factors associated with overall contraception use, and LARC use specifically, included insurance and race and ethnicity. The overall PRI was 7.89, or an expected 8 pregnancies per 100 female individuals per year. Although 108 participants (10.2%) were eligible for EC, EC was ordered for only 6 (5.6%) of those eligible.
CONCLUSIONS AND RELEVANCE
In this cross-sectional study of sexually active adolescents presenting to the ED, the majority of participants reported using at least 1 form of contraception; however, LARCs were the least used option, and 28.9% of participants reported no contraceptive use. The unintended pregnancy risk was almost 8% in the study population. Few patients eligible for EC received it. These data suggest a high need and potential opportunity for provision of contraception services in the ED setting.

IMPORTANCE
While most patients with acute pancreatitis (AP) fulfill diagnostic criteria with characteristic abdominal pain and serum lipase levels of at least 3 times the upper limit of normal (reference range) at presentation, early imaging is often used for confirmation. A prior prediction model and corresponding point-based score were developed using nonimaging parameters to diagnose AP in patients presenting to the emergency department (ED).
OBJECTIVE
To evaluate the performance of the prediction model to diagnose AP in a prospective patient cohort.
DESIGN, SETTING, AND PARTICIPANTS
This prospective diagnostic study included consecutive adult patients presenting to the ED between January 1, 2020, and March 9, 2021, at 2 large academic medical centers in the northeastern US with serum lipase levels at least 3 times the upper limit of normal. Patients transferred from outside institutions or with malignant disease and established intra-abdominal metastases, acute trauma, or altered mentation were excluded. Data were analyzed from October 15 to October 23, 2023.
EXPOSURES
Participants were assigned scores for initial serum lipase level, number of prior AP episodes, prior cholelithiasis, abdominal surgery within 2 months, presence of epigastric pain, pain of worsening severity, duration from pain onset to presentation, and pain level at ED presentation.
MAIN OUTCOME AND MEASURES
A final diagnosis of AP, established by expert review of hospitalization records.
RESULTS
Prospective scores in 349 participants (mean [SD] age, 53.0 [18.8] years; 184 women [52.7%]; 66 Black [18.9%]; 199 White [57.0%]) demonstrated an area under the receiver operating characteristics curve of 0.91. A score of at least 6 points achieved highest accuracy (F score, 82.0), corresponding to a sensitivity of 81.5%, specificity of 85.9%, positive predictive value of 82.6%, and negative predictive value of 85.1% for AP diagnosis. Early computed tomography or magnetic resonance imaging was performed more often in participants predicted to have AP (116 of 155 [74.8%] with a score ≥6 vs 111 of 194 [57.2%] with a score <6; P < .001). Early imaging revealed an alternative diagnosis in 8 of 116 participants (6.9%) with scores of at least 6 points, 1 of 93 (1.1%) with scores of at least 7 points, and 1 of 73 (1.4%) with scores of at least 8 points.
CONCLUSIONS AND RELEVANCE
In this multicenter diagnostic study, the prediction model demonstrated excellent AP diagnostic accuracy. Its application may be used to avoid unnecessary confirmatory imaging.
