Prenatal stress and externalizing behaviors in childhood and adolescence: A systematic review and meta-analysis.

Accumulating evidence suggests that psychological distress during pregnancy is linked to offspring risk for externalizing outcomes (e.g., reactive/aggressive behaviors, hyperactivity, and impulsivity). Effect sizes across studies have varied widely, however, due to differences in study design and methodology, including control for the confounding continuation of distress in the postnatal period. Clarifying these inconsistencies is necessary to guide the precision of prevention efforts and inform public health policies. A meta-analysis was conducted with 55 longitudinal studies to investigate the association between prenatal psychological distress (anxiety, depression, and perceived stress) and offspring externalizing behaviors. Results revealed a significant but small effect (r = .160) of prenatal distress on externalizing behaviors. The magnitude of the prenatal effect size remained largely unchanged after adjusting for postnatal distress (r = .159), implicating a unique effect of psychological distress during the prenatal period in the etiology of externalizing behaviors. Moderation tests showed that prenatal effects did not vary based on type and timing of psychological distress during pregnancy. Greater instability of distress from prenatal to postnatal periods predicted larger effects. Prenatal effects were comparable across most externalizing outcomes, consistent with the common comorbidity of externalizing spectrum disorders, although effects appeared smaller for nonaggressive rule-breaking (vs. aggressive) behaviors. Significant associations persisted across all developmental periods, appearing slightly larger in early childhood. We discuss these results in the context of developmental and psychobiological theories of externalizing behavior, offer preliminary clinical and public health implications, and highlight directions for future research including the need for longitudinal studies with more racially and socioeconomically diverse families.

Research Review: A systematic review and meta-analysis of infant and toddler temperament as predictors of childhood attention-deficit/hyperactivity disorder.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder with onset as early as preschool and impairment across the lifespan. Temperament factors, specifically those that theoretically map onto ADHD symptoms, may be early markers of risk for developing later childhood ADHD that could be identifiable in infancy or toddlerhood. This meta-analysis examined the associations between these early temperamental factors and later symptoms and diagnosis of ADHD and mapped early temperament constructs onto the three ADHD symptom dimensions. METHODS: A systemic review of the literature was conducted to identify prospective longitudinal studies that included theoretically relevant temperament constructs (sustained attention, activity level, inhibition, and negative emotionality) examined from birth to 36 months old and ADHD (symptoms or diagnosis) in preschool or childhood. The association between each temperament construct and ADHD outcomes was examined using pooled standardized estimates in meta-analyses. RESULTS: Forty-eight articles (n = 112,716 infants/toddlers) prospectively examined temperament and the relation to childhood ADHD symptoms or diagnosis. Activity level (k = 18) in infancy and toddlerhood was moderately associated with childhood ADHD (r = .39, CI = 0.27, 0.51, p < .001). Moderate effect sizes were also observed for sustained attention (k = 9; r = -.28, CI = -0.42, -0.12, p < .001) and negative emotionality (k = 33; r = .25, CI = 0.16, 0.34, p < .001) with ADHD. The specificity of each temperament construct for later ADHD symptom dimensions was such that activity level and negative emotionality were predictive of all three symptom dimensions (i.e., inattention, hyperactivity/impulsivity, and combined), whereas sustained attention was only associated with combined symptoms. CONCLUSIONS: Infant and toddler temperament is an early risk factor for the development of childhood ADHD that could be utilized for early intervention identification. Yet, this systematic review found that relatively few prospective longitudinal studies have examined sustained attention (k = 9) and inhibition (k = 15) in infancy and toddlerhood in relation to later ADHD highlighting the need for further research.

Reproductive Decision-Making Capacity in Women With Psychiatric Illness: A Systematic Review.

BACKGROUND: Decision-making capacity can be affected by psychiatric illness. Women who have psychiatric illness who make decisions about their reproductive health may require evaluation of their decision-making capacity. OBJECTIVE: This article aims to characterize existing literature about capacity evaluations in women with psychiatric illness making reproductive decisions. METHODS: We conducted a systematic review searching PubMed, EMBASE, Ovid PsycINFO, and ClinicalTrials.gov databases through July 2020. Articles were evaluated for relevance to inclusion criteria, first by title and abstract screening then by reading the full text of articles. Our inclusion criteria were case reports and studies that involved women of childbearing age with psychiatric illness making obstetrical decisions for whom decision-making capacity was evaluated. We qualitatively analyzed our data by examining themes within the studies, such as the circumstances of the referral and characteristics of reproductive decision-making. We also collected information about the clinical circumstances, such as the clinical setting (e.g., inpatient or outpatient, in primarily psychiatric or obstetric care) and who made the determination of capacity. RESULTS: We identified 18 articles, which included 22 distinct patient cases and 27 distinct obstetrical decisions. Decisions about termination of pregnancy were most common, which were 10 of 27 decisions. Decisions about timing and mode of delivery accounted for 7 and 5 decisions, respectively. The most common psychiatric diagnosis reported was schizophrenia, which was present in 8 patients. Major depression and bipolar disorder were also frequently reported, present in 3 and 5 patients, respectively. CONCLUSION: Patients who make health care decisions must have decision-making capacity. A patient with psychiatric illness does not inherently lack capacity, and in fact, most patients with psychiatric illness have decision-making capacity. Psychiatric illness, however, can add complexity to obstetrical medical decision-making. Reasons for this complexity include the involvement of many stakeholders, the often time-sensitive nature of these decisions, and the potentially unpredictable course of psychiatric illness. Successful management of these cases involves multidisciplinary collaboration, the use of preventative ethics through advanced care planning, and identification of a guardian or surrogate decision-maker when a patient is determined to lack decision-making capacity or for a patient who has capacity through advanced care planning.

A systematic review of community pharmacy initiatives to improve treatment of depression and pain: Focus on types of programs and patient-reported outcomes.

INTRODUCTION: Depression and pain are common, disabling, mutually exacerbating conditions. Many patients living with these conditions present to community pharmacies on a regular schedule to purchase both prescribed and over-the-counter medications. Community-pharmacy based programs have been developed to improve depression and pain outcomes. METHODS: The PRISMA guidelines were utilized to answer the following question: In patients with depression and/or pain, what is the effect of the existing community pharmacy programs on depression and/or pain outcomes. Queried databases included Pubmed, EMBASE, and PsychINFO. DistillerSR was used to organize the screening, abstraction, and review of data. All potential articles were evaluated by two authors, and conflicts were discussed to achieve resolution. In addition to primary outcomes, sources of potential bias and quality indicators were abstracted for every article. RESULTS: Three thousand nine hundred and twenty articles were reviewed, and 13 studies met eligibility criteria (n = 7 for depression; n = 6 for pain). Most studies demonstrated improvement in measures of depression or pain. However, compared to usual care or other control conditions, most of the depression and pain-specific interventions did not provide additional symptomatic benefit. The community pharmacy-based interventions were superior for other outcomes including medication adherence, reducing stigma, improvement in self-efficacy, and improvement in general management of disease. CONCLUSION: Community pharmacies may be uniquely positioned to deliver interventions that improve outcomes associated with successful depression and pain treatment outcomes. However, the benefits of published community pharmacy-based treatments for actually improving depression and pain severity has not yet been established. Innovative interventions and additional research may be needed to achieve clinical success for pharmacy interventions for depression and pain.

Meta-analysis of age and actigraphy-assessed sleep characteristics across the lifespan.

STUDY OBJECTIVES: Sleep quantity and continuity vary across the lifespan. Actigraphy is a reliable and widely used behavioral measure of sleep in research and personal health monitoring. This meta-analysis provides a novel examination of whether age (in years) is associated with actigraphy-assessed sleep across the lifespan. METHODS: A systematic search of PubMed, Embase.com, Cochrane CENTRAL, and PsycINFO using "actigraphy" and "sleep" terms provided 7079 titles/abstracts; studies of individuals with known psychiatric or medical comorbidities were excluded. Ninety-one articles (N = 23 365) provided data for six meta-analyses examining sleep duration (k = 89), sleep efficiency (k = 58), bedtime (k = 19) and waketime (k = 9) for individuals ages 6-21, and bedtime (k = 7) and waketime (k = 7) for individuals ages 22 and older. RESULTS: At older ages, sleep duration was shorter (r = -0.12) and sleep efficiency was lower (r = -0.05). Older age was associated with later bedtime (r = 0.37) and wake-up time (r = 0.24) from ages 6-21, whereas older age was associated with earlier bedtime (r = -0.66) and wake-up time (r = -0.59) for ages 22 and above. The strength of these associations was modified by study continent, but not by any other moderator. CONCLUSIONS: Age was negatively associated with actigraphy-assessed sleep duration and efficiency, but the effects were small in magnitude. On the other hand, large associations were observed between age and sleep timing, despite a smaller literature and the absence of analyzable data for ages 30-60. Changes in sleep timing, rather than changes in sleep duration or continuity, may better characterize the effects of age on human sleep.

Exercise interventions preserve hippocampal volume: A meta-analysis.

Hippocampal volume is a marker of brain health and is reduced with aging and neurological disease. Exercise may be effective at increasing and preserving hippocampal volume, potentially serving as a treatment for conditions associated with hippocampal atrophy (e.g., dementia). This meta-analysis aimed to identify whether exercise training has a positive effect on hippocampal volume and how population characteristics and exercise parameters moderate this effect. Studies met the following criteria: (a) controlled trials; (b) interventions of physical exercise; (c) included at least one time-point of hippocampal volume data before the intervention and one after; (d) assessed hippocampal volume using either manual or automated segmentation algorithms. Animal studies, voxel-based morphometry analyses, and multi-modal interventions (e.g., cognitive training or meditation) were excluded. The primary analysis in n = 23 interventions from 22 published studies revealed a significant positive effect of exercise on total hippocampal volume. The overall effect was significant in older samples (65 years of age or older) and in interventions that lasted over 24 weeks and had less than 150 min per week of exercise. These findings suggest that moderate amounts of exercise for interventions greater than 6 months have a positive effect on hippocampal volume including in older populations vulnerable to hippocampal atrophy.

Systematic review of plasma/packed red blood cell ratio on survival in ruptured abdominal aortic aneurysms.

BACKGROUND: The ideal perioperative fluid resuscitation for patients with ruptured abdominal aortic aneurysms (rAAAs) is unknown. It has been shown in trauma studies that a higher ratio of plasma and platelets to packed red blood cells confers a mortality benefit. Controversy remains whether this is true also in the rAAA population. The objective of the present study was to investigate the benefit of a greater ratio of plasma/packed red blood cells in patients with rAAAs. METHODS: A health sciences librarian searched four electronic databases, including PubMed, Embase, Cochrane, and ClinicalTrials.gov, using concepts for the terms "fluid resuscitation," "survival," and "ruptured abdominal aortic aneurysm." Two reviewers independently screened the studies that were identified through the search strategy and read in full any study that was potentially relevant. Studies were included if they had compared the mortality of patients with rAAAs who had received a greater ratio of plasma to other component therapy with that of patients who had received a lower ratio. The risk of bias was assessed using the ROBINS-I (risk of bias in nonrandomized studies of interventions) validated tool, and evidence quality was rated using the GRADE (grades of recommendation assessment, development, and evaluation) profile. No data synthesis or meta-analysis was planned or performed, given the anticipated paucity of research on this topic and the high degree of heterogeneity of available studies. RESULTS: Our search identified seven observational studies for inclusion in the present review. Of these seven studies, three found an associated decrease in mortality with a greater ratio of plasma to packed red blood cells. The remaining four found no significant differences. The overall risk of bias was serious, and the evidence quality was very low. CONCLUSIONS: Overall, the findings from the available studies would suggest that for patients who have undergone open surgery for a rAAA, mortality tends to be decreased when the amount of plasma transfused perioperatively is similar to the amount of packed red blood cells. However, the included studies reported very low-quality evidence based solely on highly heterogeneous observational studies, and further research is warranted.

Improving e-book access via a library-developed full-text search tool.

PURPOSE: This paper reports on the development of a tool for searching the contents of licensed full-text electronic book (e-book) collections. SETTING: The Health Sciences Library System (HSLS) provides services to the University of Pittsburgh's medical programs and large academic health system. BRIEF DESCRIPTION: The HSLS has developed an innovative tool for federated searching of its e-book collections. Built using the XML-based Vivísimo development environment, the tool enables a user to perform a full-text search of over 2,500 titles from the library's seven most highly used e-book collections. From a single "Google-style" query, results are returned as an integrated set of links pointing directly to relevant sections of the full text. Results are also grouped into categories that enable more precise retrieval without reformulation of the search. RESULTS/EVALUATION: A heuristic evaluation demonstrated the usability of the tool and a web server log analysis indicated an acceptable level of usage. Based on its success, there are plans to increase the number of online book collections searched. CONCLUSION: This library's first foray into federated searching has produced an effective tool for searching across large collections of full-text e-books and has provided a good foundation for the development of other library-based federated searching products.

Use of Web-based library resources by medical students in community and ambulatory settings.

PURPOSE: The purpose was to evaluate the use of Web-based library resources by third-year medical students. SETTING/PARTICIPANTS/RESOURCES: Third-year medical students (147) in a twelve-week multidisciplinary primary care rotation in community and ambulatory settings. METHODOLOGY: Individual user surveys and log file analysis of Website were used. RESULTS/OUTCOMES: Twenty resource topics were compiled into a Website to provide students with access to electronic library resources from any community-based clerkship location. These resource topics, covering subjects such as hypertension and back pain, linked to curriculum training problems, full-text journal articles, MEDLINE searches, electronic book chapters, and relevant Websites. More than half of the students (69%) accessed the Website on a daily or weekly basis. Over 80% thought the Website was a valuable addition to their clerkship. DISCUSSION/CONCLUSION: Web-based information resources can provide curriculum support to students for whom access to the library is difficult and time consuming.
