Feasibility and acceptability of an online mental health intervention for pregnant women and their partners: a mixed method study with a pilot randomized control trial. BMC Pregnancy Childbirth 2023; 23:739. [PMID: 37853333 PMCID: PMC10585730 DOI: 10.1186/s12884-023-06031-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 09/26/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND Untreated perinatal mood and anxiety disorders (PMAD) have short- and long-term health and social consequences; online cognitive behavioral therapy (CBT) interventions can reduce symptoms. Despite partner support being protective online interventions rarely target couples. This study builds on research on an existing CBT-based intervention, the Mothers and Babies Online Course (eMB), by testing its feasibility with prenatal couples. METHODS We conducted a pilot, randomized, controlled feasibility trial using a 1:1 parallel design. To be eligible, participant dyads were pregnant people (between 13-30 weeks gestation and with a score of 10 or greater on either the GAD-7 or PHQ-9 scale indicating elevated symptoms of anxiety or depression) and their cohabitating partners, living in Missouri, with access to the internet; both in the dyad consented to participate. Recruitment occurred via Facebook ads, flyers, and a snowball approach. The intervention group received eMB, and the control group received a list of community resources. We examined retention and adherence data extracted from eMB analytics and study databases. All participants were given depression and anxiety scales at baseline, 4 and 8 weeks to test preliminary efficacy; satisfaction and acceptability were measured at trial end (i.e., eight weeks) and via interview. RESULTS There were 441 people who responded to recruitment materials, 74 pregnant people were screened; 19 partners did not complete enrolment, and 25 dyads were ineligible. There were 15 dyads per group (N = 30) who enrolled; all completed the study. The survey response rate was 90% but partners required nearly twice the number of reminders. No participant completed all lessons. Mean depression and anxiety scores dropped over time for dyads in control (M = -1.99, -1.53) and intervention (M = -4.80, -1.99). Intervention pregnant people's anxiety significantly decreased (M = -4.05; 95% CI [0.82, 7.27]) at time two compared to control. Twelve pregnant people and four partners participated in post-intervention interviews and suggested improvements for eMB. CONCLUSION Online dyadic interventions can potentially reduce PMAD symptoms. However, to feasibly study eMB with couples, strategies to increase program adherence are necessary. Tailoring interventions to overtly include partners may be advantageous.

Abstract
BACKGROUND Online health interventions increase access to care, are acceptable to end users and effective for treating mental and physical health disorders. However, less is known about interventions to prevent and treat perinatal mood and anxiety disorders (PMADs). This review synthesizes existing research on PMAD prevention and treatment by exploring the treatment modalities and efficacy of online interventions and examining the inclusion of underserved populations in PMAD research. METHODS Using PRISMA guidelines, authors conducted a systematic review of peer-reviewed literature published between 2008 and 2018 on online interventions aimed to prevent or treat PMADs. The authors also assessed quality. Eligible articles included perinatal women participating in preventive studies or those aimed to reduce symptoms of PMADs and utilized a Web-based, Internet, or smartphone technology requiring an online component. This study excluded telephone-based interventions that required one-on-one conversations or individualized, text-based responses without a Web-based aspect. RESULTS The initial search yielded 511 articles, and the final analysis included 23 articles reporting on 22 interventions. Most studies used an experimental design. However, no study achieved an excellent or good quality rating. Psychoeducation and cognitive-behavioral therapies (CBTs) were most common. Several interventions using CBT strategies significantly decreased depression or anxiety. Four studies recruited and enrolled mainly people identifying as low-income or of a racial or ethnic minority group. Attrition was generally high across studies. DISCUSSION More research using rigorous study designs to test PMAD interventions across all perinatal times is needed. Future research needs to engage diverse populations purposefully.

Patient judgments about hypertension control: the role of patient numeracy and graph literacy. J Am Med Inform Assoc 2022; 29:1829-1837. [PMID: 35927964 PMCID: PMC9552283 DOI: 10.1093/jamia/ocac129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 06/27/2022] [Accepted: 07/19/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE To assess the impact of patient health literacy, numeracy, and graph literacy on perceptions of hypertension control using different forms of data visualization. MATERIALS AND METHODS Participants (Internet sample of 1079 patients with hypertension) reviewed 12 brief vignettes describing a fictitious patient; each vignette included a graph of the patient's blood pressure (BP) data. We examined how variations in mean systolic blood pressure, BP standard deviation, and form of visualization (eg, data table, graph with raw values or smoothed values only) affected judgments about hypertension control and need for medication change. We also measured patient's health literacy, subjective and objective numeracy, and graph literacy. RESULTS Judgments about hypertension data presented as a smoothed graph were significantly more positive (ie, hypertension deemed to be better controlled) then judgments about the same data presented as either a data table or an unsmoothed graph. Hypertension data viewed in tabular form was perceived more positively than graphs of the raw data. Data visualization had the greatest impact on participants with high graph literacy. DISCUSSION Data visualization can direct patients to attend to more clinically meaningful information, thereby improving their judgments of hypertension control. However, patients with lower graph literacy may still have difficulty accessing important information from data visualizations. CONCLUSION Addressing uncertainty inherent in the variability between BP measurements is an important consideration in visualization design. Well-designed data visualization could help to alleviate clinical uncertainty, one of the key drivers of clinical inertia and uncontrolled hypertension.

Impact of Home Blood Pressure Data Visualization on Hypertension Medical Decision Making in Primary Care. Ann Fam Med 2022; 20:305-311. [PMID: 35879086 PMCID: PMC9328720 DOI: 10.1370/afm.2820] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Revised: 11/30/2021] [Accepted: 01/03/2022] [Indexed: 11/09/2022] Open
Abstract
PURPOSE Evidence shows the value of home blood pressure (BP) monitoring in hypertension management. Questions exist about how to effectively incorporate these readings into BP follow-up visits. We developed and implemented a tool that combines clinical and home BP readings into an electronic health record (EHR)-integrated visualization tool. We examined how this tool was used during primary care visits and its effect on physician-patient communication and decision making about hypertension management, comparing it with home BP readings on paper. METHODS We video recorded the hypertension follow-up visits of 73 patients with 15 primary care physicians between July 2018 and April 2019. During visits, physicians reviewed home BP readings with patients, either directly from paper or as entered into the EHR visualization tool. We used conversation analysis to analyze the recordings. RESULTS Home BP readings were viewed on paper for 26 patients and in the visualization tool for 47 patients. Access to home BP readings during hypertension management visits, regardless of viewing mode, positioned the physician and patient to assess BP management and make decisions about treatment modification, if needed. Length of BP discussion with the visualization tool was similar to or shorter than that with paper. Advantages of the visualization tool included ease of use, and enhanced and faster sense making and decision making. Successful use of the tool required patients' ability to obtain their BP readings and enter them into the EHR via a portal, and an examination room configuration that allowed for screen sharing. CONCLUSIONS Reviewing home BP readings using a visualization tool is feasible and enhances sense making and patient engagement in decision making. Practices and their patients need appropriate infrastructure to realize these benefits.

Abstract
Young adults experiencing homelessness (YAEH) with pregnancy history are at higher depression risk. Receiving social support is protective for depression in pregnancy. This study differentiates social support sources associated with depression by pregnancy history among YAEH.Using a subsample of data collected from YAEH in seven US cities that were collected through REALYST, we conducted stratified logistic regression models (by pregnancy history) to identify support sources associated with depression. Logistic regression analysis including the interaction term (i.e., pregnancy history x support sources) using the full sample was then conducted.A higher proportion with pregnancy history reported depression compared to those without. Support from home-based peers was significantly associated with reduced depression risks among YAEH with pregnancy history, but not among youth without. Home-based supports were less frequently indicated by homeless female youth with pregnancy experience.Home-based social support is protective against major depression for YAEH with pregnancy experience. Findings of this study suggest that interventions addressing depression among YAEH should take their pregnancy history and social support sources into consideration. Specifically, for YAEH with pregnancy history, facilitating supportive social ties with home-based peers may be promising in reducing their depression risks.

Home blood pressure data visualization for the management of hypertension: using human factors and design principles. BMC Med Inform Decis Mak 2021; 21:235. [PMID: 34353322 PMCID: PMC8340525 DOI: 10.1186/s12911-021-01598-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Accepted: 07/28/2021] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Home blood pressure measurements have equal or even greater predictive value than clinic blood pressure measurements regarding cardiovascular outcomes. With advances in home blood pressure monitors, we face an imminent flood of home measurements, but current electronic health record systems lack the functionality to allow us to use this data to its fullest. We designed a data visualization display for blood pressure measurements to be used for shared decision making around hypertension. METHODS We used an iterative, rapid-prototyping, user-centred design approach to determine the most appropriate designs for this data display. We relied on visual cognition and human factors principles when designing our display. Feedback was provided by expert members of our multidisciplinary research team and through a series of end-user focus groups, comprised of either hypertensive patients or their healthcare providers required from eight academic, community-based practices in the Midwest of the United States. RESULTS A total of 40 participants were recruited to participate in patient (N = 16) and provider (N = 24) focus groups. We describe the conceptualization and development of data display for shared decision making around hypertension. We designed and received feedback from both patients and healthcare providers on a number of design elements that were reported to be helpful in understanding blood pressure measurements. CONCLUSIONS We developed a data display for substantial amounts of blood pressure measurements that is both simple to understand for patients, but powerful enough to inform clinical decision making. The display used a line graph format for ease of understanding, a LOWESS function for smoothing data to reduce the weight users placed on outlier measurements, colored goal range bands to allow users to quickly determine if measurements were in range, a medication timeline to help link recorded blood pressure measurements with the medications a patient was taking. A data display such as this, specifically designed to encourage shared decision making between hypertensive patients and their healthcare providers, could help us overcome the clinical inertia that often results in a lack of treatment intensification, leading to better care for the 35 million Americans with uncontrolled hypertension.

Home blood pressure data visualization for the management of hypertension: designing for patient and physician information needs. BMC Med Inform Decis Mak 2020; 20:195. [PMID: 32811489 PMCID: PMC7432548 DOI: 10.1186/s12911-020-01194-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Accepted: 07/20/2020] [Indexed: 01/06/2023] Open
Abstract
Background Nearly half of US adults with diagnosed hypertension have uncontrolled blood pressure. Clinical inertia may contribute, including patient-physician uncertainty about how variability in blood pressures impacts overall control. Better information display may support clinician-patient hypertension decision making through reduced cognitive load and improved situational awareness. Methods A multidisciplinary team employed iterative user-centered design to create a blood pressure visualization EHR prototype that included patient-generated blood pressure data. An attitude and behavior survey and 10 focus groups with patients (N = 16) and physicians (N = 24) guided iterative design and confirmation phases. Thematic analysis of qualitative data yielded insights into patient and physician needs for hypertension management. Results Most patients indicated measuring home blood pressure, only half share data with physicians. When receiving home blood pressure data, 88% of physicians indicated entering gestalt averages as text into clinical notes. Qualitative findings suggest that including a data visualization that included home blood pressures brought this valued data into physician workflow and decision-making processes. Data visualization helps both patients and physicians to have a fuller understanding of the blood pressure ‘story’ and ultimately promotes the activated engaged patient and prepared proactive physician central to the Chronic Care Model. Both patients and physicians expressed concerns about workflow for entering and using home blood pressure data for clinical care. Conclusions Our user-centered design process with physicians and patients produced a well-received blood pressure visualization prototype that includes home blood pressures and addresses patient-physician information needs. Next steps include evaluating a recent EHR visualization implementation, designing annotation functions aligned with users’ needs, and addressing additional stakeholders’ needs (nurses, care managers, caregivers). This significant innovation has potential to improve quality of care for hypertension through better patient-physician understanding of control and goals. It also has the potential to enable remote monitoring of patient blood pressure, a newly reimbursed activity, and is a strong addition to telehealth efforts.

Abstract
Objective. Uncontrolled hypertension is driven by clinical uncertainty around blood pressure data. This research sought to determine whether decision support-in the form of enhanced data visualization-could improve judgments about hypertension control. Methods. Participants (Internet sample of patients with hypertension) in 3 studies (N = 209) viewed graphs depicting blood pressure data for fictitious patients. For each graph, participants rated hypertension control, need for medication change, and perceived risk of heart attack and stroke. In study 3, participants also recalled the percentage of blood pressure measurements outside of the goal range. The graphs varied by systolic blood pressure mean and standard deviation, change in blood pressure values over time, and data visualization type. Results. In all 3 studies, data visualization type significantly affected judgments of hypertension control. In studies 1 and 2, perceived hypertension control was lower while perceived need for medication change and subjective perceptions of stroke and heart attack risk were higher for raw data displays compared with enhanced visualization that employed a smoothing function generated by the locally weighted smoothing algorithm. In general, perceptions of hypertension control were more closely aligned with clinical guidelines when data visualization included a smoothing function. However, conclusions were mixed when comparing tabular presentations of data to graphical presentations of data in study 3. Hypertension was perceived to be less well controlled when data were presented in a graph rather than a table, but recall was more accurate. Conclusion. Enhancing data visualization with the use of a smoothing function to minimize the variability present in raw blood pressure data significantly improved judgments about hypertension control. More research is needed to determine the contexts in which graphs are superior to data tables.

Abstract
Background Uncontrolled hypertension is a significant health problem in the United States, even though multiple drugs exist to effectively treat this chronic disease. Objective As part of a larger project developing data visualizations to support shared decision making about hypertension treatment, we conducted a series of studies to understand how perceptions of hypertension control were impacted by data variations inherent in the visualization of blood pressure (BP) data. Methods In 3 Web studies, participants (internet sample of patients with hypertension) reviewed a series of vignettes depicting patients with hypertension; each vignette included a graph of a patient’s BP. We examined how data visualizations that varied by BP mean and SD (Study 1), the pattern of change over time (Study 2), and the presence of extreme values (Study 3) affected patients’ judgments about hypertension control and the need for a medication change. Results Participants’ judgments about hypertension control were significantly influenced by BP mean and SD (Study 1), data trends (whether BP was increasing or decreasing over time—Study 2), and extreme values (ie, outliers—Study 3). Conclusions Patients’ judgment about hypertension control is influenced both by factors that are important predictors of hypertension related-health outcomes (eg, BP mean) and factors that are not (eg, variability and outliers). This study highlights the importance of developing data visualizations that direct attention toward clinically meaningful information.

Abstract
OBJECTIVE The purpose of this study was to determine the information needs of primary care patients as they review clinic visit notes to inform information that should be contained in an after-visit summary (AVS). METHOD We collected data from 15 patients with an acute illness and 14 patients with a chronic disease using semi-structured interviews. The acute patients reviewed seven major sections, and chronic patients reviewed eight major sections of a simulated, but realistic visit note to identify relevant information needs for their AVS. RESULTS Patients in the acute illness group identified the Plan, Assessment and History of Present Illness the most as important note sections, while patients in the chronic care group identified Significant Lab Data, Plan, and Assessment the most as important note sections. DISCUSSION This study was able to identify primary care patients' information needs after clinic visit. Primary care patients have information needs pertaining to diagnosis and treatment, which may be the reason why both patient groups identified Plan and Assessment as important note sections. Future research should also develop and assess an AVS based on the information gathered in this study and evaluate its usefulness among primary care patients. PRACTICE IMPLICATIONS The results of this study can be used to inform the development of an after-visit summary that assists patients to fully understand their treatment plan, which may improve treatment adherence.

Abstract
Infrastructure improvements such as pedestrian crosswalks that calm traffic and increase access to physical activity opportunities could alleviate important barriers to active living in underserved communities with outdated built environments. The purpose of this study was to explore how the built environment influences street-crossing behaviors and traffic speeds in a low-income neighborhood with barriers to active living in Columbia, Missouri. In 2013, a signalized pedestrian crosswalk and 400-ft-long median was constructed along a busy 5-lane, high-speed arterial highway linking low-income housing with a park and downtown areas. Data collection occurred prior to June 2012, and after June 2013, completion of the project at the intervention site and control site. Direct observation of street-crossing behaviors was performed at designated intersections/crosswalks or non-designated crossing points. Traffic volume and speed were captured using embedded magnetic traffic detectors. At the intervention site, designated crossings increased at the new crosswalk (p < 0.001), but not at non-designated crossings (p = 0.52) or designated crossings at intersections (p = 0.41). At the control site, there was no change in designated crossings (p = 0.94) or non-designated crossings (p = 0.79). Motor vehicles traveling above the speed limit of 35 mph decreased from 62,056 (46 %) to 46,256 (35 %) (p < 0.001) at the intervention site and increased from 57,891 (49 %) to 65,725 (59 %) (p < 0.001) at the control site. The installation of a signalized crosswalk facilitated an increase in safe street crossings and calmed traffic volume and speed in an underserved neighborhood. We believe these findings have significant public health implications that could be critical to advocacy efforts to improve infrastructure projects in similar communities.

Abstract
To synthesize findings from previous studies assessing information needs of primary care patients on the Internet and other information sources in a primary care setting. A systematic review of studies was conducted with a comprehensive search in multiple databases including OVID MEDLINE, CINAHL, and Scopus. The most common information needs among patients were information about an illness or medical condition and treatment methods, while the most common information sources were the Internet and patients' physicians. Overall, patients tend to prefer the Internet for the ease of access to information, while they trust their physicians more for their clinical expertise and experience. Barriers to information access via the Internet include the following: socio-demographic variables such as age, ethnicity, income, education, and occupation; information search skills; and reliability of health information. CONCLUSION Further research is warranted to assess how to create accurate and reliable health information sources for both Internet and non-Internet users.

Abstract
Background Technology-based aids for lifestyle change are becoming more prevalent for chronic conditions. Important “digital divides” remain, as well as concerns about privacy, data security, and lack of motivation. Researchers need a way to characterize participants’ readiness to use health technologies. To address this need, we created an instrument to measure patient readiness to engage with health technologies among adult patients with chronic conditions. Methods Initial focus groups to determine domains, followed by item development and refinement, and exploratory factor analysis to determine final items and factor structure. The development sample included 200 patients with chronic conditions from 6 family medicine clinics. From 98 potential items, 53 best candidate items were examined using exploratory factor analysis. Pearson’s Correlation for Test/Retest reliability at 3 months. Results The final instrument had 28 items that sorted into 8 factors with associated Cronbach’s alpha: 1) Health Information Need (0.84), 2) Computer/Internet Experience (0.87), 3) Computer Anxiety (0.82), 4) Preferred Mode of Interaction (0.73), 5) Relationship with Doctor (0.65), 6) Cell Phone Expertise (0.75), 7) Internet Privacy (0.71), and 8) No News is Good News (0.57). Test-retest reliability for the 8 subscales ranged from (0.60 to 0.85). Conclusion The Patient Readiness to Engage in Health Internet Technology (PRE-HIT) instrument has good psychometric properties and will be an aid to researchers investigating technology-based health interventions. Future work will examine predictive validity.

Abstract
BACKGROUND The increase in the adoption of electronic health records (EHR) has contributed to physicians and nurses experiencing information overload. To address the problem of information overload, an assessment of the information needs of physicians and nurses will assist in understanding what they view as useful information to make patient care more efficient. OBJECTIVE To analyse studies that assessed the information needs and information-seeking behaviour of physicians and nurses in a primary care setting to develop a better understanding of what information to present to physicians when they making clinical decisions. METHOD A literature review of studies was conducted with a comprehensive search in PubMed, cinahl, scopus, as well as examination of references from relevant papers and hand-searched articles to identify articles applicable to this review. RESULTS Of the papers reviewed the most common information needs found among physicians and nurses were related to diagnoses, drug(s) and treatment/therapy. Colleagues remain a preferred information source among physicians and nurses; however, a rise in Internet usage is apparent. CONCLUSION Physicians and nurses need access to the Internet and job-specific resources to find practitioner-oriented information. In addition, effective usage of resources is important for improving patient care.

Abstract
BACKGROUND AND OBJECTIVES Electronic patient portals are increasingly common, but there is little information regarding attitudes of faculty and residents at academic medical centers toward them. METHODS The primary objective was to investigate attitudes toward electronic patient portals among primary care residents and faculty and changes in faculty attitudes after implementation. The study design included a pre-implementation survey of 39 general internal medicine and family medicine residents and 43 generalist faculty addressing attitudes and expectations of a planned patient portal and also a pre- and post-implementation survey of general internal medicine and family medicine faculty physicians. The survey also addressed email communication with patients. RESULTS Prior to portal implementation, residents reported receiving much less e-mail from patients than faculty physicians; 68% and 9% of residents and faculty, respectively, reported no email exchange in a typical month. Residents were less likely to agree with allowing patients to view selected parts of their medical record on-line than faculty physicians (57% and 81%, respectively). Physicians who participated in the portal's pilot implementation had expected workload to increase (64% agreed), but after implementation, 87% of those responding were neutral or disagreed that workload had increased. After implementation, only 33% believed quality of care had improved compared to 55% who had expected it to improve prior to implementation. CONCLUSIONS Residents and faculty physicians need to be prepared for a changing environment of electronic communication with patients. Some positive and negative expectations of physicians toward enhanced electronic access by patients were not borne out by experience.

We examined how primary care patients use the Internet, particularly patient characteristics associated with Internet use. METHODS We surveyed patients in five primary care clinic waiting rooms. Patients who had used email or the Internet in the past month (Internet users) were asked how often they used a computer for a variety of tasks. Participants who reported not using the Internet were asked about several potential barriers to Internet use. RESULTS We approached 713 patients, and 638 (89.6%) completed questionnaires; 499 (78%) were Internet users and 139 (22%) were non-users. Lack of computer access and not knowing how to use email or the Internet were the most common barriers to Internet use. Younger age, higher education and income, better health, and absence of a chronic illness were associated with Internet use. After controlling for age and other variables, chronic illness was no longer associated with Internet use. CONCLUSIONS Internet use was high among our primary care patients. The major factor associated with Internet use among patients with chronic conditions was their age. If older adults with chronic illness are to reap the benefits of health information technology, their Internet access will need to be improved. Institutions that are planning to offer consumer health information technology should be aware of groups with lower Internet access.

Abstract
Internet-based secure communication portals (portal) have the potential to enhance patient care via improved patient-provider communications. This study examines differences among primary care patients' perceptions when contemplating using, enrolling to use, and using a portal for health care purposes. A total of 3 groups of patients from 1 Midwestern academic medical center were surveyed at different points in time: (1) Waiting Room survey asking about hypothetical interest in using a portal to communicate with their physicians; (2) patient portal Enrollment survey; and (3) Follow-up postenrollment experience survey. Those who enroll and use a patient portal have different demographic characteristics and interest levels in selected portal functions (eg, e-mailing providers, viewing medical records online, making appointments) and initially perceive only limited improvements in care because of the portal. These differences have potential market implications and provide insight into selecting and maintaining portal functions of greater interest to patients who use the portal.

Abstract
BACKGROUND In past research, children with older siblings were more likely than others to wheeze at age 2 years, but less likely by age 6 years. Higher infection transmission and a down-regulated allergic immune response as a result of these infections, respectively, were suggested as the causes. However, in a study of children aged 0-3 years in a low-income urban community in New York City, USA, with high asthma prevalence, we observed no birth-order effect. OBJECTIVE To evaluate the association between birth order and atopy and respiratory symptoms in 4-year-old children attending Head Start programs in NYC. METHODS Respiratory symptoms were assessed by questionnaire for 1005 children (mean age 4.0 years) living in high asthma prevalence neighbourhoods. Serum was collected from a subgroup of the children (n=494) and specific IgE responses to dust mite, cockroach, mouse, and cat allergens were measured. RESULTS Prevalence of specific IgE (> or =0.35 IU/mL) did not differ significantly among first (35%), second (35%), and later-born children (28%) (P=0.23). Increasing birth order was associated with increasing prevalence of respiratory symptoms in the prior year, including wheeze (first 20%, second 27%, third or later 35%; P<0.001), being awakened at night by cough (28%, 33%, 38%; P=0.005), emergency department visits (14%, 17%, 21%; P=0.02) and hospitalizations for difficulty breathing (6.1%, 6.6%, 10%; P=0.04). The associations of birth order with respiratory symptoms were statistically significant only for the non-seroatopic children and those without an asthmatic parent. CONCLUSIONS Non-seroatopic children with older siblings were more likely than those without older siblings to have respiratory symptoms at age 4 years. Although the stability of these associations over time remains to be determined, the differences in findings between this study and our previous NYC birth cohort study suggest that patterns of asthma development may vary even among low-income populations within the same city.

The nonintegrin laminin binding protein (p67 LBP) is expressed on a subset of activated human T lymphocytes and, together with the integrin very late activation antigen-6, mediates avid cellular adherence to laminin.

Abstract
A search for genes expressed in activated T cells revealed that the nonintegrin, 67-kDa laminin binding protein (p67 LBP) is expressed on the surface of a subset (10-15%) of activated peripheral blood T cells. Surface p67 LBP expression is detectable by FACS using the anti-p67 LBP mAb, MLuC5, within 6 h of T cell activation with phorbol dibutyrate and ionomycin, peaks 18-36 h postactivation, and persists for 7-10 days. The subset of T cells expressing p67 LBP is composed of mature, single-positive cells (85% CD4+8-, 15% CD4-8+) of memory cell phenotype (100% CD45 RO+/CD45 RA-). The p67 LBP+ T cells also express the integrin alpha6 chain (CD49f), which is known to associate with p67 LBP on tumor cells. In addition, the p67 LBP+ T cells express the integrin beta1, which associates with alpha6 in the laminin-specific integrin receptor very late activation Ag (VLA)-6 (alpha6beta1). Expression of an exogenous cDNA encoding the 37-kDa LBP precursor (p37 LBPP) confers p67 LBP surface expression on a p67 LBP-negative Jurkat T cell line (B2.7). Expression of p67 LBP induces B2.7 transfectants to adhere to laminin, but avid laminin binding depends on coexpression of VLA-6. Taken together, these data indicate that p67 LBP is an activation-induced surface structure on memory T cells that, together with VLA-6, mediates cellular adherence to laminin.

Intracerebroventricular injection of interleukin-1 suppresses peripheral lymphocyte function in the primate. Neuroimmunomodulation 1997; 4:12-8.

Abstract
The cytokine interleukin-1 (IL-1) can act within the brain to induce peripheral endocrine and immune effects. In the rodent intracerebroventricular (i.c.v.) injection of IL-1 activates the hypothalamic-pituitary-adrenal axis and suppresses peripheral immune function by a CRH-dependent mechanism. It is unknown if IL-1 can similarly act within the brain to cause peripheral immunosuppression in the primate and to what extent this could be attributed to the IL-1-induced increase in ACTH and cortisol levels. In this study we have characterized the pituitary-adrenal and peripheral lymphocyte responses to IL-1 alpha (4.2 micrograms) infused over 30 min into the lateral ventricle of ovariectomized monkeys (n = 5) as compared with responses to an intravenous (i.v.) ACTH infusion (1 microgram/h for 7 h; n = 4). Four serial blood samples were obtained for ACTH and cortisol determination and for lymphocyte isolation during a 1-hour baseline and for 7 h after IL-1 or ACTH. Lymphocyte proliferation was measured by 3H-thymidine uptake in response to stimulation with phytohemagglutinin. In all 5 animals, IL-1 alpha caused rapid and profound suppression of lymphocyte mitogen responsiveness for 7 h. Baseline lymphocyte proliferation was 51,800 +/- 9,780 cpm and suppressed to a nadir of 4.5% with a mean of 23% baseline over 7 h (p < 0.001). Mean ACTH and cortisol levels increased from 33 +/- (SEM) 4.6 pg/ml and 43 +/- 4.0 micrograms/dl, respectively, during the control period to 90 +/- 14 pg/ml and 56 +/- 2.6 micrograms/dl, respectively, after IL-1 (p < 0.01). Before i.v. ACTH, baseline lymphocyte proliferation was 49,400 +/- 2,820 cpm, and suppressed to a mean of 64% of baseline during ACTH infusion (p < 0.05). Mean ACTH and cortisol levels increased from 48 +/- 5.0 pg/ml and 43 +/- 2.0 micrograms/dl, respectively, to 170 +/- 34 pg/ml and 66 +/- 2.3 micrograms/dl, respectively, during the ACTH infusion (p < 0.01). Lymphocyte suppression after i.c.v. IL-1 was much more profound than after i.v. ACTH (p < 0.01); the area under the IL-1 response curve was 37% of the area under the ACTH response curve. These studies demonstrate for the first time in the primate that centrally injected IL-1 has a profound suppressive effect on lymphocyte function. They also show for the first time in any species that there appears to be a significant immunosuppressive message produced by i.c.v. IL-1 that is not accounted for by the associated increases in ACTH and cortisol.

The binding affinity of human IgG for its high affinity Fc receptor is determined by multiple amino acids in the CH2 domain and is modulated by the hinge region. J Exp Med 1991; 173:1483-91.

Abstract
A family of chimeric immunoglobulins (Igs) bearing the murine variable region directed against the hapten dansyl linked to human IgG1, -2, -3, and -4 has been characterized with respect to binding to the human high affinity Fc gamma receptor, Fc gamma RI. Chimeric IgG1 and -3 have the highest affinity association (Ka = 10(9) M-1), IgG4 is 10-fold reduced from this level, and IgG2 displays no detectable binding. A series of genetic manipulations was undertaken in which domains from the strongly binding subclass IgG3 were exchanged with domains from the nonbinding subclass IgG2. The subclass of the CH2 domain was found to be critical for determining IgG receptor affinity. In addition, the hinge region was found to modulate the affinity of the IgG for Fc gamma RI, possibly by determining accessibility of Fc gamma RI to the binding site on Fc. A series of amino acid substitutions were engineered into the CH2 domain of IgG3 and IgG4 at sites considered potentially important to Fc receptor binding based on homology comparisons of binding and nonbinding IgG subclasses. Characterization of these mutants has revealed the importance for Fc gamma RI association of two regions of the genetic CH2 domain separated in primary structure by nearly 100 residues. The first of these is the hinge-link or lower hinge regions, in which two residues, Leu (234) and Leu(235) in IgG1 and -3, are critical to high affinity binding. Substitution at either of these sites reduces the IgG association constant by 10-100-fold. The second region that appears to contribute to receptor binding is in a hinge-proximal bend between two beta strands within the CH2 domain, specifically, Pro(331) in IgG1 and -3. As a result of beta sheet formation within this domain, this residue lies within 11 A of the hinge-link region. Substitution at this site reduces the Fc receptor association constant by 10-fold.

Abstract
Using domain switch chimeric antibodies, we confirm the important role of CH2 in complement activation. In addition, we demonstrate that the structures responsible for the differential ability of human IgG1 and IgG4 to activate complement are located at the COOH-terminal part (from residue 292 to 340) of the CH2 domain. The amino acids in CH2 that might be involved in complement interaction are discussed. While CH3 contributes to efficient complement activation, CH3 from IgG2 and CH3 IgG3 are equally effective.

Abstract
To localize regions on IgG bound by rheumatoid factors (RF), we studied IgM RF binding to chimeric IgG antibodies consisting of murine V regions fused to human constant regions. Using a modified RF ELISA, we showed that polyclonal RF from rheumatoid arthritis patients bound IgG1, 2, and 4 strongly; IgG3 was also bound, although less well. The majority of 18 monoclonal RF from patients with Waldenstrom's macroglobulinemia bound IgG1, 2, and 4 only. In contrast to RF from RA, 14 of 18 monoclonal RF did not react with IgG3. Only 3 of 18 monoclonal RF bound IgG3 well. By shuffling C region domains between IgG3 and IgG4, we showed that sequence variation in the CH3 domain is responsible for the differential binding of monoclonal RF to IgG3 and IgG4. Hybrid IgG3/IgG4 antibodies containing the CH3 domain of IgG4 were bound by monoclonal RF, whereas those containing the CH3 domain of IgG3 were not. To evaluate the contribution of the N-linked carbohydrate moiety at Asn-297 to RF binding sites on IgG, we measured RF binding to aglycosylated IgG antibodies produced by mutating Asn-297 to another amino acid. Glycosylated and aglycosylated IgG1, 2, and 4 were bound identically by monoclonal and polyclonal RF. Aglycosylated IgG3, however, was bound better than glycosylated IgG3 by polyclonal RF and by IgG3-reactive monoclonal RF.
