RESUMEN

Respiratory syncytial virus (RSV) is a common cause of respiratory infections, causing significant morbidity and mortality, especially in young children. Why RSV infection in children is more severe as compared to healthy adults is not fully understood. In the present study, we infect both pediatric and adult human nose organoid-air liquid interface (HNO-ALIs) cell lines with two contemporary RSV isolates and demonstrate how they differ in virus replication, induction of the epithelial cytokine response, cell injury, and remodeling. Pediatric HNO-ALIs were more susceptible to early RSV replication, elicited a greater overall cytokine response, demonstrated enhanced mucous production, and manifested greater cellular damage compared to their adult counterparts. Adult HNO-ALIs displayed enhanced mucus production and robust cytokine response that was well controlled by superior regulatory cytokine response and possibly resulted in lower cellular damage than in pediatric lines. Taken together, our data suggest substantial differences in how pediatric and adult upper respiratory tract epithelium responds to RSV infection. These differences in epithelial cellular response can lead to poor mucociliary clearance and predispose infants to a worse respiratory outcome of RSV infection.

RESUMEN

The National Cancer Institute's (NCI) Health Information National Trends Survey (HINTS) is a nationally representative survey of U.S. adults in which 12-17% of respondents report a cancer history. To increase representation from adult cancer survivors, in 2021, NCI sampled survivors from three Surveillance, Epidemiology, and End Results (SEER) program cancer registries: Iowa, New Mexico, and the Greater Bay Area. Sampling frames were stratified by time since diagnosis and race/ethnicity, with nonmalignant tumors and non-melanoma skin cancers excluded. Participants completed a self-administered postal questionnaire. The overall response rate for HINTS-SEER (N = 1,234) was 12.6%; a non-response bias analysis indicated few demographic differences between respondents and the pool of sampled patients in each registry. Most of the sample was 10+ years since diagnosis (n = 722; 60.2%); 392 respondents were 5 to < 10 years since diagnosis (29.6%); and 120 were < 5 years since diagnosis (10.2%). Common cancers included male reproductive (n = 304; 24.6%), female breast (n = 284; 23.0%), melanoma (n = 119; 9.6%), and gastrointestinal (n = 106; 8.6%). Tumors were mostly localized (67.8%; n = 833), with 22.4% (n = 282) regional, 6.2% (n = 72) distant, and 3.7% (n = 47) unknown. HINTS-SEER data are available by request and may be used for secondary analyses to examine a range of social, behavioral, and healthcare outcomes among cancer survivors.

RESUMEN

Youth with dental anxiety are at an increased risk of poor oral health but current tools used to identify dental anxiety in children in clinical settings are hampered by several limitations. This study assessed the psychometric properties of a measure of implicit associations with dental stimuli, the Affective Misattribution Procedure for dental stimuli (AMP-D) in 68 youth between the ages of 9 and 17 years. Measures of self-reported dental anxiety and parental perceptions of child dental anxiety were also administered. The internal consistency of the AMP-D was high (KR-20 = 0.96) and 1-week test-retest reliability was in the acceptable range (r = 0.75). The AMP-D was correlated with self-reported dental anxiety, providing evidence of construct validity. The psychometric properties of the AMP-D suggest it could be a useful tool in identifying youth with dental anxiety, particularly when concerns regarding self-representation may compromise the validity of self-reported anxiety.

RESUMEN

INTRODUCTION: Patient-centered communication (PCC) is one important component of patient-centered care and seen as a goal for most clinical encounters. Previous research has shown that higher PCC is related to an increase in healthy behaviors and less morbidity, among other outcomes. Given its importance, the National Cancer Institute (NCI) commissioned a monograph in 2007 to synthesize the existing literature on PCC and determine measurement objectives and strategies for measuring this construct, with a particular focus on cancer survivors. Based on this effort, a seven-item PCC scale was included on the Health Information National Trends Survey (HINTS), a probability-based survey of the US adult population. This study used HINTS data collected in 2018 to evaluate the psychometric properties of the PCC scale for the general US adult population including measures of reliability and validity. RESULTS: Through an exploratory factor analysis, the seven-item PCC scale was shown to be unidimensional with good internal consistency (Cronbach's alpha = .92). A confirmatory factor analysis verified the factor structure. Other construct validity metrics included known groups and discriminant validity. Known group comparisons were conducted for several sociodemographic factors and health self-efficacy confirming a priori assumptions. Discriminant validity tests with measures of social support and anxiety/depression showed relatively weak associations. CONCLUSIONS: The psychometric properties of this scale demonstrate its scientific utility for both surveillance research and other smaller-scale studies. Given its association with many health outcomes, it can also be used to better understand the dynamics in a clinical encounter.

RESUMEN

Despite recommendations promoting noninvasive delivery room (DR) ventilation, local historical preterm DR noninvasive ventilation rates were low (50%-64%). Project aims were to improve DR noninvasive ventilation rate in very low birth weight (VLBW) neonates (<1500 g) with a focus on decreasing DR intubations for ineffective positive pressure ventilation (PPV). Methods: We addressed drivers for improving noninvasive ventilation and decreasing intubations for ineffective PPV through plan-do-study-act cycles. Outcome measures were intubation for ineffective PPV (defined as intubation for heart rate <100 despite ongoing PPV) and final respiratory support in the DR. Our process measure was adherence to division-wide DR-intubation guidelines. Balancing measures were maximum FiO2 and hypothermia. We analyzed data using statistical process control charts and special cause variation rules. Results: There were 139 DR intubations among 521 VLBW neonates between January 2015 and February 2020. The noninvasive ventilation rate upon intensive care nursery admission was higher than historically reported at 73% and sustained throughout the project. The intubation rate for ineffective PPV was 10% and did not change. The number of VLBW neonates between intubations for ineffective PPV increased from 6.1 to 8.0. Ten intubations did not comply with guidelines. Balancing measures were unaffected. Conclusions: Noninvasive ventilation rates were higher than historically reported and remained high. After plan-do-study-act cycles, the number of VLBW neonates between intubations for ineffective PPV increased without impacting balancing measures. Our data demonstrate that effective ventilation (heart rate > 100) using noninvasive support is possible in up to 90% of VLBW infants but requires ongoing PPV training.

RESUMEN

OBJECTIVE: To examine if the relationship between neuroticism and physician avoidance/physician visit concerns are mediated by perceptions that cancer is associated with death ("cancer mortality salience"; CMS) for cancer survivors to inform public health interventions and tailored health communications. METHODS: Cancer survivors comprised 42.3% of the total sample (n = 525). Participants completed a 4-item neuroticism scale, 4-item cancer perceptions scale, and 4-item physician avoidance and concerns scale. Multiple linear regression models were used to assess relationships among variables for cancer survivors and separately for those without a history of cancer. RESULTS: Neuroticism was positively associated with CMS for cancer survivors, b = 0.26, (p < 0.001), and those without cancer, b = 0.22, (p < 0.001). There was an association between neuroticism and physician avoidance among cancer survivors with temporally distant treatment courses after controlling for CMS, b = 0.56 (p = 0.006), but not for those currently or recently having had undergone treatment (p = 0.949). There was also an indirect relationship between neuroticism and physician visit concerns that was mediated by CMS for cancer survivors, b = 0.07, CI = [0.03, 0.13], but this relationship was again driven by cancer survivors with more distal treatment courses. CONCLUSIONS: High neuroticism in cancer survivors is associated with physician avoidance and physician visit concerns when treatment is temporally distant. Interventions aimed at decoupling the association between cancer and death can help increase the willingness of cancer survivors to attain cancer care follow-ups and healthcare more generally.

RESUMEN

BACKGROUND: To investigate the underlying causes of a sudden increase in HIV among people who inject drugs (PWID) and initiate an appropriate response to the outbreak, we engaged in in-depth qualitative interviews with members of the PWID community in Lawrence and Lowell, Massachusetts. METHODS: We interviewed 34 PWID who were currently or recently unstably housed, then transcribed interviews and coded transcripts, grouping codes into categories from which we identified key themes. RESULTS: Participants described a heightened threat of overdose prompting PWID to inject together, increasing opportunities for sharing injection equipment. There were misunderstandings about safe injection practices to prevent HIV transmission and a low threshold for injection-related risk taking. Stigma regarding HIV prevented conversations about HIV status. Less thought was given to sexual risks than injection-related risks for HIV transmission. CONCLUSIONS: We found multiple facilitators of HIV transmission. Additional HIV education and prevention interventions focusing on both injection and sexual risk practices would benefit this population, in addition to structural interventions such as increased access and availability of syringe service programs.

RESUMEN

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200.

RESUMEN

Although HIV diagnoses among women have declined in recent years in the United States (U.S.), women accounted for 19% of new HIV diagnoses in 2016. In addition, women comprise 24% of the 973,846 persons living with HIV infection in the U.S. However, HIV prevention interventions targeting women are limited. We performed a review on HIV infection in women to increase awareness, improve overall care, and inform intervention development. A systematic literature review was conducted using literature published in PubMed, PsychINFO (EBSCO), and Scopus from July 2000 and June 2017. We included studies that: (1) were conducted in the U.S., (2) enrolled at least 50 HIV-positive women, and (3) utilized a case-control, cohort, or surveillance study design. Of 7497 articles, 48 articles met inclusion criteria. HIV diagnoses among women declined 32% between 2001 and 2016. In 2016, 61% of diagnoses in women were among African American women, and 56% were in the South. Women reported barriers to HIV care largely due to psychosocial challenges and social/structural determinants of health (SDH) barriers. Though new diagnoses among women have declined, racial and regional disparities remain. HIV prevention and research efforts with women are vital to inform interventions and reduce disparities.

RESUMEN

Objective: Research with non-cancer survivor populations finds affective variables to be important determinants of physical activity. This study assessed the ability of explicit and implicit affective variables to predict the physical activity of cancer survivors, above that accounted for by cognitive variables. The study also tested whether the affective variables were connected to physical activity directly or indirectly through their association with behavioural intentions. Design: In a cross-sectional design, cancer survivors (n = 122) completed questionnaires and an implicit affect task. Main outcome measures: Self-report measures assessed three affective variables (e.g. positive affective associations), five cognitive variables (e.g. cognitive beliefs), physical activity estimates, behavioural intentions and participants also completed an implicit affect task regarding physical activity. Results: Two of the three explicit affect variables and the implicit affect variable accounted for significant variability in physical activity estimates beyond that accounted for by the cognitive variables. Positive affective associations were the strongest predictor in multivariate analyses. Behavioural intentions did not mediate the link between the affect variables and physical activity estimates. Conclusions: Explicit and implicit affective variables are direct and unique predictors of physical activity in cancer survivors. Physical activity interventions for cancer survivors should target both explicit affect and implicit affect.

RESUMEN

OBJECTIVE: To assess the accuracy of real-time delivery room resuscitation documentation. DESIGN: Retrospective observational study. SETTING: Level 3 academic neonatal intensive care unit. PARTICIPANTS: Fifty infants with video recording of neonatal resuscitation. MAIN OUTCOME MEASURES: Vital sign assessments and interventions performed during resuscitation. The accuracy of written documentation was compared with video gold standard. RESULTS: Timing of initial heart rate assessment agreed with video in 44/50 (88%) records; the documented heart rate was correct in 34/44 (77%) of these. Heart rate and oxygen saturation were documented at 5 min of life in 90% of resuscitations. Of these, 100% of heart rate and 93% of oxygen saturation values were correctly recorded. Written records accurately reflected the mode(s) of respiratory support for 89%-100%, procedures for 91%-100% and medications for 100% of events. CONCLUSION: Real-time documentation correctly reflects interventions performed during delivery room resuscitation but is less accurate for early vital sign assessments.

RESUMEN

Objectives. To describe and control an outbreak of HIV infection among people who inject drugs (PWID).Methods. The investigation included people diagnosed with HIV infection during 2015 to 2018 linked to 2 cities in northeastern Massachusetts epidemiologically or through molecular analysis. Field activities included qualitative interviews regarding service availability and HIV risk behaviors.Results. We identified 129 people meeting the case definition; 116 (90%) reported injection drug use. Molecular surveillance added 36 cases to the outbreak not otherwise linked. The 2 largest molecular groups contained 56 and 23 cases. Most interviewed PWID were homeless. Control measures, including enhanced field epidemiology, syringe services programming, and community outreach, resulted in a significant decline in new HIV diagnoses.Conclusions. We illustrate difficulties with identification and characterization of an outbreak of HIV infection among a population of PWID and the value of an intensive response.Public Health Implications. Responding to and preventing outbreaks requires ongoing surveillance, with timely detection of increases in HIV diagnoses, community partnerships, and coordinated services, all critical to achieving the goal of the national Ending the HIV Epidemic initiative.

RESUMEN

Kigali, Rwanda lacks a centralized sewer system, which leaves residents to choose between on-site options; the majority of residents in informal settlements use pit latrines as their primary form of sanitation. When their pits fill, the pits are either sealed, or emptied; emptying is often done by hand and then dumped in the environment, putting the residents and the broader population at risk of infectious disease outbreaks. In this paper, we used revealed and stated preference models to: (1) estimate the demand curve for improved emptying services; and, (2) evaluate household preferences and the willingness to pay (WTP) for different attributes of improved emptying services. We also quantify the costs of improved service delivery at different scales of production. The study included 1167 households from Kigali, Rwanda across 30 geographic clusters. Our results show that, at a price of US$79 per pit, 15% of all the pits would be emptied by improved emptying services, roughly the current rate of manual emptying. Grouping empties by neighborhood and ensuring that each truck services an average of four households per day could reduce the production costs to US$44 per empty, ensuring full cost coverage at that price. At a lower price of US$24, we estimate that the sealing of pits might be fully eliminated, with full coverage of improved emptying services for all pits; this would require a relatively small subsidy of US$20 per empty. Our results show that households had strong preferences for fecal sludge (FS) treatment, formalized services (which include worker protections), and distant disposal. The results from the study indicate a few key policies and operational strategies that can be used for maximizing the inclusion of low-income households in safely managed sanitation services, while also incorporating household preferences and participation.

RESUMEN

INTRODUCTION: Placebo analgesia often results when a pain reduction treatment message is delivered to a patient or research participant. Little information exists regarding the psychological changes that are immediately triggered by the delivery of a treatment message. OBJECTIVES: This experiment tested the impact of 3 different analgesic treatment messages on the expectations, feelings, and electrodermal activity of participants anticipating a pain stimulus. METHODS: In laboratory sessions, healthy participants (N = 138) were randomly assigned to 1 of 4 conditions in a between-subject design. The design included a no treatment message control condition and 3 treatment message conditions: a standard analgesic message, an analgesic treatment with side-effect message, and a double-blind analgesic message. After the treatment message manipulation, measures were taken of: treatment efficacy expectations, pain experience expectations, pretask anxiety, positive affect, negative affect, and electrodermal activity. RESULTS: Overall, the dependent measures showed relatively few correlations. Furthermore, across all 3 message conditions, treatment-specific expectations were greatly increased compared with the control condition. Finally, participants in the double-blind message condition displayed elevated negative affect. CONCLUSION: All 3 analgesic treatment messages produced a stronger immediate influence on treatment efficacy expectations than on the other dependent measures. Treatment messages can alter negative affect along with expectancies. The low correlations found between dependent measures suggest that different patterns of psychological responses may emerge from analgesic treatment messages depending on contextual factors.

RESUMEN

BACKGROUND: Currently, little is known about the implicit evaluations that cancer survivors have for health behaviors, such as eating fruits and vegetables. Understanding both the implicit and explicit evaluations of fruit and vegetable consumption among cancer survivors may aid future interventions for changing motivations and intentions in this higher risk population. METHODS: A cross-sectional study at a university cancer center assessed explicit and implicit evaluations of fruit and vegetable consumption among 122 cancer survivors. The explicit evaluations regarding fruit and vegetable consumption were self-report data. To obtain implicit evaluations, participants completed an implicit evaluation task, the Affect Misattribution Paradigm. Moderating variables of time since first cancer treatment and if participants had a prior cancer occurrence were also self-reported. RESULTS: Simple correlations found no significant association between the implicit and explicit evaluations of fruit and vegetable consumption. Moderation regression analyses showed that the implicit and explicit evaluations became negatively associated as time since first treatment increased and when participants had a prior cancer occurrence. CONCLUSION: The results support the view that implicit and explicit measures of fruit and vegetable consumption diverge for cancer survivors, consistent to implicit and explicit evaluations in other domains and samples. Further, the association between these evaluations differed depending on time since first treatment and if they have been treated for a prior cancer occurrence. By knowing more about implicit and explicit positive evaluations, and their moderators, it may be possible for interventionists to alter cancer survivors' motivation and intention to eat fruits and vegetables.

RESUMEN

There is an ethical obligation to notify individuals about potential pain associated with diagnoses, treatments, and procedures; however, supplying this information risks inducing nocebo hyperalgesia. Currently, there are few empirically derived strategies for reducing nocebo hyperalgesia. Because nocebo effects are linked to negative affectivity, we tested the hypothesis that a positive-affect induction can disrupt nocebo hyperalgesia from verbal suggestion. Healthy volunteers (N = 147) were randomly assigned to conditions in a 2 (affect induction: positive vs neutral) by 2 (verbal suggestion: no suggestion vs suggestion of pain increase) between-subjects design. Participants were induced to experience positive or neutral affect by watching movie clips for 15 minutes. Next, participants had an inert cream applied to their nondominant hand, and suggestion was manipulated by telling only half the participants the cream could increase the pain of the upcoming cold pressor test. Subsequently, all participants underwent the cold pressor test (8 ± 0.04°C), wherein they submerged the nondominant hand and rated pain intensity on numerical rating scales every 20 seconds up to 2 minutes. In the neutral-affect conditions, there was evidence for the nocebo hyperalgesia effect: participants given the suggestion of pain displayed greater pain than participants not receiving this suggestion, P's < 0.05. Demonstrating a blockage effect, nocebo hyperalgesia did not occur in the positive-affect conditions, P's > 0.5. This is the first study to show that positive affect may disrupt nocebo hyperalgesia thereby pointing to a novel strategy for decreasing nocebo effects without compromising the communication of medical information to patients in clinical settings.

RESUMEN

HIV continuum of care analyses in Georgia during 2013 revealed that 82% of adolescents and adults living with HIV knew their diagnosis and that 75% were linked to care. However, of all persons in Georgia living with HIV in 2014, only 60% had at least one HIV care visit, and just 48% were retained in care. Understanding barriers for HIV testing, linkage, and retention in youth may strengthen HIV-related encounters and improve patient outcomes. We conducted 17 qualitative focus groups with HIV-positive and -negative youth, ages 18-24 years, from the Atlanta Metropolitan Statistical Area. Using computer-assisted thematic analyses, we examined focus group responses on ways to approach youth for community-based HIV testing and how service providers should discuss a new positive HIV diagnosis with youth. Of 68 participants, 85% were male, 90% were African American, 68% were HIV positive, and 50% had high school education or less. Mean age was 21.5 years (standard deviation: 1.8 years). Thematic analyses identified the following three key themes for approaching someone for HIV testing: (1) discretion, (2) being candid about testing, and (3) incentivizing testing. When service providers discuss an HIV positive test, participants recommended enhanced emotional support and reassurance of a potential healthy life span despite an HIV diagnosis. Community-based testing may be a viable option for increasing HIV screening of at-risk youth. Structuring an empathetic new diagnosis disclosure that addresses potential misconceptions and describes successful HIV treatment is essential to improving linkage to care among youth.

RESUMEN

BACKGROUND: Latino men who have sex with men (MSM) experienced a 13% increase in HIV diagnoses from 2010 to 2014, more than any other racial/ethnic subgroup of MSM in the United States. If current HIV diagnoses rates persist, about one in four Latino MSM in the United States will be diagnosed with HIV during their lifetime. Although some efficacious HIV prevention interventions for Latino MSM exist, none have focused on couples. This paper describes the protocol of a randomized controlled trial (RCT) to test the preliminary efficacy of a couple-based HIV prevention intervention that is culturally tailored for Latino men and their same-sex partners. METHODS: The RCT will determine the preliminary efficacy of Connecting Latinos en Pareja (CLP) to increase the proportion of anal sex acts that are HIV protected (i.e., anal sex acts in which condoms, pre-exposure prophylaxis (PrEP), treatment as prevention (TasP), or a combination thereof, are used to reduce risk of HIV transmission). CLP builds upon previous couple-based interventions with white and black MSM by incorporating biomedical prevention techniques, such as PrEP and TasP, implementing a framework responsive to the couple's serostatus, and addressing the socio-cultural factors that influence HIV risk among Latino MSM. We also include input from community stakeholders, members of the target population, and a community advisory board as part of intervention development. Assessments will be conducted at baseline, and 3- and 6-months post-intervention to examine the intervention effects on outcomes (HIV-protected sex acts), and factors potentially mediating or moderating intervention effects. DISCUSSION: This paper describes an innovative RCT that incorporates multiple HIV prevention techniques for Latino MSM in couples, regardless of serostatus. The ongoing involvement of community stakeholders, members of the target population, and a community advisory board is emphasized, and plans for widespread dissemination and application of findings into practice are discussed.

RESUMEN

Strong gay identity among white men who have sex with men (MSM) has been associated with decreased HIV risk, but data for black and Latino MSM (BLMSM) are inconclusive. We examined gay identity and HIV risk among BLMSM to inform social and structural HIV intervention strategies. BLMSM were administered a computerized survey as part of an HIV research study during 2011-2012 conducted in New York City. We used a brief scale of Gay Identity Questionnaire. After data analysis, Stage I (not fully accepting) and Stage II (fully accepting) gay identity were determined based on participant responses. We used logistic regression to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for the association between gay identity with HIV risk and social determinant factors. Among 111 self-identified BLMSM (median age = 32 years, 68.4% with some college or higher education), 34.2 reported receptive anal sex without condoms in the previous three months. Gay Identity Questionnaire Scale assessment indicated that 22 (19.8%) were Stage I, and 85 (76.6%) were Stage II in this BLMSM sample. Stage II gay identity was more likely seen among BLMSM with high involvement in the gay community (aOR 3.2; CI 1.00, 10.26) and less likely among BLMSM who exchanged sex for food or shelter (aOR 0.15; CI 0.02, 0.98). Fully accepting gay identity may be protective for BLMSM as it relates to transactional sex; these factors warrant further research and consideration as part of HIV prevention strategies.
