Barriers and motivators to undertaking physical activity in adults over 70-a systematic review of the quantitative literature.

BACKGROUND: Physical activity (PA) has multiple benefits for older adults (≥70 years old). Despite this many older adults do not undertake the World Health Organisation guideline recommended amount of PA. This systematic review examines barriers and motivators to PA in adults aged ≥70 years. METHODS: We analysed the quantitative literature, including observational studies and baseline data from randomised controlled trials. Studies examining specific diseases (e.g. cognitive impairment), or care home residents were excluded. Database searches of ASSIA, CINAHL, Embase, Medline, PsycINFO and Web of Science were undertaken on 7 March 2023. Quality assessment was performed using the ROBANS tool. We synthesised the results using the socioecological model. The protocol was registered on PROSPERO (CRD42021160503). RESULTS: We identified 37 papers, n = 26,961, age 70-101 years (median 78), 62% female. We undertook a narrative review; meta-analysis was not possible. Overall risk of bias was low. A total of 23 studies addressed barriers, seven motivators, seven both. The most cited barriers were: concern about physical health/fitness (14 studies), lack of motivation/interest (13 studies), fear of falls/history of falling (11 studies) and environmental barriers (10 studies). Key motivators were: support from family/friends (five studies), social interaction (five studies), personal benefits (five studies) and outside facilities (five studies). Results varied across gender, age, functional ability and geographical location. DISCUSSION: To maximise PA in older adults, important modifiable factors identified in this review should be targeted: support from healthcare professionals; reducing fear of falls; and prioritising ease of access and safety of outdoor facilities. When considering future policy, a person-centred, age group appropriate approach will have the most impact.

Data release: targeted systematic literature search for tick and tick-borne pathogen distributions in six countries in sub-Saharan Africa from 1901 to 2020.

BACKGROUND: Surveillance data documenting tick and tick-borne disease (TBD) prevalence is needed to develop risk assessments and implement control strategies. Despite extensive research in Africa, there is no standardized, comprehensive review. METHODS: Here we tackle this knowledge gap, by producing a comprehensive review of research articles on ticks and TBD between 1901 and 2020 in Chad, Djibouti, Ethiopia, Kenya, Tanzania, and Uganda. Over 8356 English language articles were recovered. Our search strategy included 19 related MeSH terms. Articles were reviewed, and 331 met inclusion criteria. Articles containing mappable data were compiled into a standardized data schema, georeferenced, and uploaded to VectorMap. RESULTS: Tick and pathogen matrixes were created, providing information on vector distributions and tick-pathogen associations within the six selected African countries. CONCLUSIONS: These results provide a digital, mappable database of current and historical tick and TBD distributions across six countries in Africa, which can inform specific risk modeling, determine surveillance gaps, and guide future surveillance priorities.

Penicillin-binding protein redundancy in Bacillus subtilis enables growth during alkaline shock.

Penicillin-binding proteins (PBPs) play critical roles in cell wall construction, cell shape maintenance, and bacterial replication. Bacteria maintain a diversity of PBPs, indicating that despite their apparent functional redundancy, there is differentiation across the PBP family. Apparently-redundant proteins can be important for enabling an organism to cope with environmental stressors. In this study, we evaluated the consequence of environmental pH on PBP enzymatic activity in Bacillus subtilis. Our data show that a subset of PBPs in B. subtilis change activity levels during alkaline shock and that one PBP isoform is rapidly modified to generate a smaller protein (i.e., PBP1a to PBP1b). Our results indicate that a subset of the PBPs are favored for growth under alkaline conditions, while others are readily dispensable. Indeed, we found that this phenomenon could also be observed in Streptococcus pneumoniae, implying that it may be generalizable across additional bacterial species and further emphasizing the evolutionary benefit of maintaining many, seemingly-redundant periplasmic enzymes.IMPORTANCEMicrobes adapt to ever-changing environments and thrive over a vast range of conditions. While bacterial genomes are relatively small, significant portions encode for "redundant" functions. Apparent redundancy is especially pervasive in bacterial proteins that reside outside of the inner membrane. While conditions within the cytoplasm are carefully controlled, those of the periplasmic space are largely determined by the cell's exterior environment. As a result, proteins within this environmentally exposed region must be capable of functioning under a vast array of conditions, and/or there must be several similar proteins that have evolved to function under a variety of conditions. This study examines the activity of a class of enzymes that is essential in cell wall construction to determine if individual proteins might be adapted for activity under particular growth conditions. Our results indicate that a subset of these proteins are preferred for growth under alkaline conditions, while others are readily dispensable.

Factors that influence older adults' participation in physical activity: a systematic review of qualitative studies.

BACKGROUND: Despite the advantages of physical activity (PA), older adults are often insufficiently active to maximise health. Understanding factors that influence PA engagement will support well-designed interventions for older people. Our aim was to review the qualitative evidence exploring the factors affecting older adults' engagement in PA. METHODS: We searched six electronic databases for studies of community-dwelling older adults (≥70 years) including qualitative methods. We excluded studies of a single-disease group, individuals with cognitive impairment and care home residents. Methodological rigour was assessed with the Critical Appraisal Skills Programme, and framework synthesis was applied using the Capability Opportunity Motivation-Behaviour (COM-B) model, which hypothesises that behaviour is influenced by three factors: capability, opportunity and motivation. RESULTS: Twenty-five studies were included in the review (N = 4,978; mean 79 years) and 32 themes were identified. Older adults' capability was influenced by functional capacity (e.g. strength) and perceived risk of injury from PA (e.g. falls). Opportunity was impacted by the environment 'fit' (e.g. neighbourhood safety), the availability of social interaction and socio-cultural ageing stereotypes. PA was motivated by identifying as an 'exerciser', health gains and experiencing positive emotions (e.g. enjoyment), whereas negative sensations (e.g. pain) reduced motivation. CONCLUSIONS: The qualitative synthesis showcased a complex web of interacting factors influencing PA between the sub-domains of COM-B, pinpointing directions for intervention, including a focus on whole systems approaches. There was a lack of research exploring PA influences in the oldest old and in low-income countries. Future research should seek to involve under-served groups, including a wider diversity of older people.

Vaccine hesitancy in pregnant Women: A narrative review.

Pregnant women are often at higher risk for morbidity and mortality due to contracting vaccine-preventable diseases that result in adverse pregnancy outcomes such as spontaneous abortion, preterm births, and congenital fetal defects. For example, health care provider recommendation is correlated with maternal acceptance of influenza vaccination, however, up to 33 % of pregnant women remain unvaccinated irrespective of provider recommendation. Vaccine hesitancy is a multifactorial problem that both the medical and public health systems need to address synergistically. Vaccine education should incorporate balanced perspectives to deliver vaccine education. This narrative review addresses four questions: 1) what are the primary concerns of pregnant women that lead them to be hesitant about receiving vaccinations; 2) to what extent does the source (e.g. provider, friend, family) of vaccine advice and information influence a pregnant person's decision to accept a vaccine; 3) how does the delivery method of vaccine education influence their decision; 4) how can categorizing patients into four distinct groups based on their opinions and behavior regarding vaccines be used to improve provider-patient communication and increase vaccine acceptance. Results from the literature show that the three most common reasons for vaccine hesitancy include: i.) fear of side effects or adverse events; ii.) lack of confidence in vaccine safety; iii.) low perception of being at high risk of infection during pregnancy and/or not having previously received the vaccination when not pregnant. We conclude that vaccine hesitancy is dynamic therefore people do not always hold a static level of vaccine hesitancy. People may move between a continuum of vaccine hesitancy for a multifactorial reasons. A framework, characterized by levels of vaccine hesitancy before and during pregnancy, was constructed to help providers find balance between promoting individual health and public health while providing vaccine education.

ADAMS project: a genetic Association study in individuals from Diverse Ancestral backgrounds with Multiple Sclerosis based in the UK.

PURPOSE: Genetic studies of multiple sclerosis (MS) susceptibility and severity have focused on populations of European ancestry. Studying MS genetics in other ancestral groups is necessary to determine the generalisability of these findings. The genetic Association study in individuals from Diverse Ancestral backgrounds with Multiple Sclerosis (ADAMS) project aims to gather genetic and phenotypic data on a large cohort of ancestrally-diverse individuals with MS living in the UK. PARTICIPANTS: Adults with self-reported MS from diverse ancestral backgrounds. Recruitment is via clinical sites, online (https://app.mantal.co.uk/adams) or the UK MS Register. We are collecting demographic and phenotypic data using a baseline questionnaire and subsequent healthcare record linkage. We are collecting DNA from participants using saliva kits (Oragene-600) and genotyping using the Illumina Global Screening Array V.3. FINDINGS TO DATE: As of 3 January 2023, we have recruited 682 participants (n=446 online, n=55 via sites, n=181 via the UK MS Register). Of this initial cohort, 71.2% of participants are female, with a median age of 44.9 years at recruitment. Over 60% of the cohort are non-white British, with 23.5% identifying as Asian or Asian British, 16.2% as Black, African, Caribbean or Black British and 20.9% identifying as having mixed or other backgrounds. The median age at first symptom is 28 years, and median age at diagnosis is 32 years. 76.8% have relapsing-remitting MS, and 13.5% have secondary progressive MS. FUTURE PLANS: Recruitment will continue over the next 10 years. Genotyping and genetic data quality control are ongoing. Within the next 3 years, we aim to perform initial genetic analyses of susceptibility and severity with a view to replicating the findings from European-ancestry studies. In the long term, genetic data will be combined with other datasets to further cross-ancestry genetic discoveries.

Projecting the impact of an ebola virus outbreak on endangered mountain gorillas.

Ebola virus is highly lethal for great apes. Estimated mortality rates up to 98% have reduced the global gorilla population by approximately one-third. As mountain gorillas (Gorilla beringei beringei) are endangered, with just over 1000 individuals remaining in the world, an outbreak could decimate the population. Simulation modeling was used to evaluate the potential impact of an Ebola virus outbreak on the mountain gorilla population of the Virunga Massif. Findings indicate that estimated contact rates among gorilla groups are high enough to allow rapid spread of Ebola, with less than 20% of the population projected to survive at 100 days post-infection of just one gorilla. Despite increasing survival with vaccination, no modeled vaccination strategy prevented widespread infection. However, the model projected that survival rates greater than 50% could be achieved by vaccinating at least half the habituated gorillas within 3 weeks of the first infectious individual.

Pregnant Women's Concerns Regarding COVID-19 and Their Willingness to Be Vaccinated.

Objectives: We investigated coronavirus disease 2019 (COVID-19) opinions, experiences, and willingness to accept COVID-19 vaccination during pregnancy at two prenatal clinics in early 2021 and early 2022. Materials and Methods: Paper questionnaires were distributed to pregnant women at prenatal care facilities in Virginia and Florida between January and April 2021 and January and April 2022. Questions regarding acceptance and opinions of the influenza vaccine served as a baseline to assess COVID-19 vaccine opinions. Associations between demographic parameters and vaccine opinions and acceptance were examined using Chi-square. A COVID-19 concern score was constructed by principal component analysis with differences between groups assessed by analysis of variance (ANOVA) and analysis of covariance (ANCOVA). Results: Many participants (40.6%) reported that the COVID pandemic had affected their pregnancy. Main themes were problems with social networks, increased stress/anxiety, and being more cautious. In 2021, 19.5% reported they would accept a COVID-19 vaccination during their pregnancy, which increased to 45.8% in 2022. Vaccine hesitancy did not vary by race or between sites, but educational attainment was significant (p < 0.001). Women with a higher concern score were more likely to report they would accept a COVID-19 vaccine. Women who would accept COVID vaccination had a positive opinion regarding the influenza vaccine. Main themes for refusing COVID-19 vaccination were concerns about side effects, lack of research/data, and mistrust of vaccines. Conclusions: The proportion of women willing to accept COVID-19 vaccination increased but remained below 50%. Willingness to accept vaccination during pregnancy was associated with higher education, higher concern about COVID-19, and a positive opinion of the influenza vaccine.

Text2Breathe: Text-Message Intervention for Parent Communication and Pediatric Asthma.

OBJECTIVE: Mobile health technology offers promise for reducing disparities in pediatric asthma care and outcomes by helping parents more effectively communicate with their children's primary care providers and manage their children's asthma. This study tested the impact of a text messaging program on emergency department utilization and asthma morbidity. METHODS: A randomized controlled trial enrolled 221 parents of Medicaid-insured children visiting the emergency departments of 2 urban children's hospitals in the Pacific Northwest for an asthma-related concern between September 2015 and February 2019. Standardized surveys were administered to parents at baseline and 12 months later to assess the primary outcomes of emergency department utilization and morbidity as well as primary care utilization, parent communication self-efficacy, and asthma self-management knowledge. The intervention group received brief in-person education on partnering with primary care providers, followed by 3 months of educational text messages. RESULTS: Participants were mostly female, English speakers, of minority race and ethnicity, and living below 200% of the federal poverty level. Negative binomial and linear regressions indicated no significant group differences in annual number of emergency department visits, morbidity, parent communication self-efficacy, or asthma self-management knowledge at 12 months' follow-up, adjusting for baseline covariates. Average annual rate of primary care visits for asthma was 35% higher in the intervention group compared to control group at follow-up (95% confidence interval 1.03-1.76, P = .03). CONCLUSIONS: This parent-focused text message intervention did not impact emergency department utilization or asthma morbidity; however, results suggest its potential for enhancing use of primary care for management of pediatric chronic conditions.

Factors Associated With Psychiatric Readmission of Youths in a Racially Diverse and Urban Hospital Setting.

OBJECTIVE: This study examined predictors of readmission to a psychiatric inpatient unit of an urban children's hospital within 1 year of discharge among a racially diverse sample of youths. METHODS: The authors retrospectively analyzed 2 years of electronic health record data of inpatient psychiatric unit admissions (N=1,604). Multivariate logistic regression and random-effects multinomial logistic regression were used for analyses. RESULTS: The estimated odds ratios for any readmission within 1 year of discharge were significantly higher for Black youths, youths insured by Medicaid, and youths with a length of stay longer than 7 days. Factors remained strongly predictive when examining multiple readmissions versus no readmissions. CONCLUSIONS: Black youths, youths insured by Medicaid, and youths with longer stays were more likely than other youths to be readmitted. Findings suggest the need for interventions such as care coordination to target predictors of readmission and the need to examine inequities in the health care system.

NanoAdventure: Development of a Text-Based Adventure Game in English, Spanish, and Chinese for Communicating about Nanotechnology and the Nanoscale.

Video games and immersive, narrative experiences are often called upon to help students understand difficult scientific concepts, such as sense of scale. However, the development of educational video games requires expertise and, frequently, a sizable budget. Here, we report on the use of an interactive text-style video game, NanoAdventure, to communicate about sense of scale and nanotechnology to the public. NanoAdventure was developed on an open-source, free-to-use platform with simple coding and enhanced with free or low-cost assets. NanoAdventure was launched in three languages (English, Spanish, Chinese) and compared to textbook-style and blog-style control texts in a randomized study. Participants answered questions on their knowledge of nanotechnology and their attitudes toward nanotechnology before and after reading one randomly assigned text (textbook, blog, or NanoAdventure game). Our results demonstrate that interactive fiction is effective in communicating about sense of scale and nanotechnology as well as the relevance of nanotechnology to a general public. NanoAdventure was found to be the most "fun" and easy to read of all text styles by participants in a randomized trial. Here, we make the case for interactive "Choose Your Own Adventure" style games as another effective tool among educational game models for chemistry and science communication.

Design and Implementation of Improved SARS-CoV-2 Diagnostic Assays To Mitigate the Impact of Genomic Mutations on Target Failure: the Xpert Xpress SARS-CoV-2 Experience.

In 2020, the U.S. Food and Drug Administration (FDA) enabled manufacturers to request emergency use authorization (EUA) to facilitate the rapid authorization of in vitro diagnostic (IVD) platforms for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Uncommon SARS-CoV-2 point mutations could cause nucleocapsid (N) gene target failure (NGTF) when using first-generation Xpert Xpress assays, so improvements were designed and implemented. In response to NGTF reports and with consideration of viral genomic information in public databases, the Xpress assays were redesigned to mitigate the impact of SARS-CoV-2 mutations on qualitative assay performance. The second-generation assays include a third gene target (RNA-dependent RNA polymerase [RdRp]) and redundant oligonucleotide probes for the N2 target. First- and second-generation assay performances were evaluated using a challenge set of samples. A second-generation assay with updated oligonucleotide chemistry received FDA EUA in September 2021. A prototype assay with oligonucleotide chemistry similar to that of the second-generation assay with FDA EUA successfully detected all three gene targets (N2, envelope [E], and RdRp) in all challenge samples (100%; 50/50), including variants with N gene mutations (g.29197C>T or g.29200C>T), which caused NGTF in the first-generation assays. Investigation and reporting of IVD target failures, public sharing of viral genomic sequence data, and the FDA EUA pathway were essential components in facilitating a short cycle time from the identification of mutations that impact the performance of an IVD assay to the design and implementation of an improved IVD assay. IMPORTANCE The SARS-CoV-2 genome has mutated during the coronavirus disease 2019 (COVID-19) pandemic. Some of these mutations have impacted the performance of nucleic acid amplification tests like PCR, which are commonly used as diagnostic tools to detect an infection. The U.S. Food and Drug Administration (FDA) emergency use authorization (EUA) process enables the rapid reformulation and regulatory authorization of improved PCRs. In our experience, the identification of SARS-CoV-2 mutations that impact PCR performance, the subsequent development of improved PCR chemistry, and the use of the FDA EUA regulatory pathway led to improved diagnostic performance during the SARS-CoV-2 pandemic that is able to keep pace with the rapidly evolving genome of SARS-CoV-2.

Large viral meningoencephalitis CSF serologic panel lacks utility in clinical decisions and outcomes.

INTRODUCTION: Accurate diagnosis of viral meningoencephalitis (VMe) and identification of the etiologic agent has clinical importance and large serology panels are available to aid in the detection of several viral pathogens. However, such panels are often send-out testing, with prolonged time to results, thus impacting the actionability of test results. We hypothesized these panels may not contribute to patient care and lack clinical utility. METHODS: A retrospective review of all VMe CSF serology panels ordered at one pediatric (n = 53; 2017-2019) and two adult (n = 200; 2019-2020) tertiary care hospitals was performed to assess test clinical utility. Panels included serology for: Adenovirus, coxsackie and echoviruses, influenza, measles, lymphocytic choriomeningitis virus, herpes simplex virus, mumps, varicella zoster, encephalitis viruses. Clinical data collected included diagnostic test results, symptoms, comorbidities, and interventions. RESULTS: In 129/200 (64.5 %) of adult cases and 37/53 (69.8 %) of pediatric cases CSF had a WBC less than 5 cells/mm2. In total, 127 (63.5 %, 127/200) adult panels had at least one positive target with 49 panels having more than one positive (38.6 %, 49/127). In 99.5 % of adult and 100 % of pediatric cases there was no change to decisions regarding starting, discontinuing, continuing, or changing antimicrobial therapy based on panel results. In no cases were potentially immunosuppressive therapies like steroid or IVIG administration delayed while awaiting the results of the panel. CONCLUSIONS: While all patients presented with neurologic symptoms, poor pre-screening for CNS inflammation using CSF WBC analysis likely contributed to poor clinical utility of the VMe panels. Large CSF serologic panels for VMe did not contribute to or add value to clinical decision making in our cohort.

Considerations regarding Interpretation of Positive SARS-CoV-2 Molecular Results with Late Cycle Threshold Values.

COVID-19 disease lies on a spectrum, ranging from completely asymptomatic to mild disease to severe and critical disease. Studies have shown that prolonged shedding or sporadic detection of SARS-CoV-2 RNA can occur long after symptom resolution. Adding to these clinical complexities is the demand for testing for SARS-CoV-2 at all stages of diseases, frequently driven by screening of asymptomatic persons, something that traditionally has not been performed for other viral respiratory diseases. This can lead to positive results from nucleic acid amplification tests (NAATs), such as RT-PCR, with late cycle threshold (CT) values near the test's limit of detection. In this commentary, we review unique attributes of COVID-19 and causes of NAAT late CT values. We provide interpretation considerations as well as strategies to aid in test interpretation.

Evaluating the feasibility of a real world pharmacovigilance study (OPTIMISE:MS).

BACKGROUND: Clinical trial populations do not fully reflect routine practice. The power of routinely collected data to inform clinical practice is increasingly recognised. METHODS: The OPTIMISE:MS pharmacovigilance study is a prospective, pragmatic observational study, conducted across 13 UK MS centres. Data were collected at the time of routine clinical visits. The first participant was recruited on 24th May 2019; data were extracted on 11th November 2021. RESULTS: 2112 participants were included (median age 44.0 years; 1570 (72%) female; 1981 (94%) relapsing-remitting MS). 639 (30%) were untreated at study entry, 205 (10%) taking interferon beta/copaxone, 1004 (47%) second/third generation DMT first line and 264 (13%) had escalated from a platform DMT. 342 clinical events were reported, of which 108 infections. There was an increased risk of adverse events in people taking second/third generation DMT (RR 3.45, 95%CI 1.57-7.60, p<0.01 vs no DMT). Unadjusted Poisson regression demonstrated increased incident adverse events in people taking natalizumab (IRR 5.28, 95%CI 1.41-19.74, p<0.05), ocrelizumab (IRR 3.24, 95%CI 1.22-8.62, p<0.05), and GA biosimilar (Brabio) (IRR 4.89, 95%CI 1.31-18.21, p<0.05) vs no DMT. CONCLUSIONS: Routinely collected healthcare data can be used to evaluate DMT safety in people with MS. These data highlight the potential of pragmatic studies to guide understanding of risks and benefits associated with DMT.

Performance of the Sofia SARS-CoV-2 Rapid Antigen Test in Symptomatic and Asymptomatic Pediatric Patients.

The sensitivity and specificity of SARS-CoV-2 antigen tests have not been widely assessed in children. We evaluated children presenting to outpatient care with Quidel Sofia SARS-CoV-2 antigen test (Sofia-Ag-RDT) compared against Cepheid Xpert Xpress SARS-CoV-2/Flu/RSV reverse transcriptase-polymerase chain reaction test from November 2020 to April 2021. Sofia-Ag-RDT had the highest sensitivity in symptomatic (82%; 95% confidence interval, 68%-91%) children.

Choosing a Birth Setting: A Shared Decision-Making Approach.

Perinatal outcomes vary widely depending on individual birth settings (birth center, home, and hospital). The purpose of this case study is to explore a patient-centered, shared decision-making approach to achieve an informed, values-based choice about birth settings. Engaging in a shared decision-making approach regarding birth setting options would support people to have the information and ability to judge for themselves how benefits and risks across birth center, home, and hospital settings would best fit with their values and personal health. A patient decision aid about birth setting options could facilitate increased equity regarding access to birth settings that offer improved perinatal health outcomes, helping to reduce perinatal health disparities in the United States.

Factors that shape pregnant women's perceptions regarding the safety of cannabis use during pregnancy.

BACKGROUND: Cannabis use among pregnant women has increased. We surveyed pregnant women in rural Pennsylvania to examine cannabis use and opinions regarding its safety during pregnancy. We examined associations between challenges of pregnancy (e.g., exhaustion, pain, nausea) and cannabis use. METHODS: A cross-sectional survey was administered to a convenience sample of English-speaking pregnant women receiving prenatal care at Geisinger, May-June 2019. Principal component analysis (PCA) was used to construct three scores (overwhelmed/exhausted, happy/optimistic, and health worries) based on 10 questions regarding common experiences during pregnancy (e.g., nausea/vomiting, pain, exhaustion, mood). A score based on four questions regarding cannabis safety during pregnancy was also constructed. RESULTS: From a maximum of 300 surveys distributed, 284 were completed (95%). Most participants were white (87%), married (49%) or living with a partner (38%), and had private health insurance (62%). Most women indicated it was unsafe to use alcohol and tobacco products during pregnancy (> 90%), but that proportion dropped to 82% and 63% regarding recreational cannabis and medical cannabis, respectively. Only women with prior cannabis use (23% of sample) continued to do so during pregnancy: 57% of women reporting daily cannabis use prior to pregnancy continued to use cannabis during pregnancy with 33% reporting daily use. Two thirds of users during pregnancy indicated they were self-medicating for: nausea (90%), anxiety (70%), insomnia (30%), and pain management (30%). Many (56%) of the women who used cannabis during pregnancy believed it is safe. Younger women and women who were overwhelmed/exhausted or less happy/optimistic were more likely to believe cannabis use is safe. Women valued healthcare provider advice more than advice from family and friends. Study strengths include a high response rate. Weaknesses include self-report and that is was a convenience sample; however, the demographics of the sample were similar to past studies. CONCLUSION: Women with a history of cannabis use, especially daily use, are at risk of continuing during pregnancy and should receive counseling. Younger women and women with greater stressors during pregnancy also are at greater risk. Screening for prior use and for stressors may identify patients that would benefit from enhanced counseling.
