RESUMO

BACKGROUND: Asset mapping is a commonly used method in public health to identify and describe the resources within a community. However, there is currently a lack of standardization in the methods used for asset mapping, which can make it difficult for users to apply the method and compare results between different studies. In this article, we present a new approach called Asset Mapping Score Analysis (AMSA), which is a framework for collecting and organizing data on community assets. We provide an example of the AMSA method through its application in the evaluation of maternal and child health resources in New Orleans, Louisiana. RESULTS: The AMSA approach consists of five steps and results in a data collection tool that uses a scoring system to quantify the functional and content areas defined by the users. This method is flexible, reproducible, quantitative, inexpensive, and can be adapted to fit the needs of different geographic areas and fields of study. It can also be repeated over time to monitor changes in systems. We conducted a pilot study to examine the participation of local maternal and child health organizations in four functional areas (education, direct services, policy/advocacy, and research) and 22 content areas. CONCLUSIONS: In addition to describing the AMSA method and providing an example of its application, we also discuss the methodological issues involved in using the AMSA approach. These include considerations related to study design, data analysis, and interpreting results. We assess the strengths, limitations, and potential future directions of the AMSA method. Finally, we present the results of our AMSA study on maternal and child health organizations in New Orleans to illustrate the utility of this approach. Our findings suggest that the AMSA method is a valuable tool for understanding and characterizing the assets and resources within a community.

RESUMO

BACKGROUND: Black older-teenaged women have disproportionately high rates of sexually transmitted infections (STI) and unintended pregnancy (UTP). Internet-based interventions can be delivered to large groups of people in a relatively inexpensive manner. In this randomized trial, we examine the efficacy of an evidence-based STI/UTP prevention intervention adapted for older teens and for Internet delivery. METHODS: Black women aged 18-19 years who were not pregnant/seeking to become pregnant were enrolled (n = 637) and randomized to an 8-session intervention or attention control and were followed up at 6/12 months postintervention. The primary outcome was defined as uptake of reliable contraceptives. Other secondary outcomes were examined, including intention to use condoms, intention to use reliable contraception, and STI or pregnancy rates. RESULTS: Overall, at baseline, reliable contraception was 54.8% and dual protection was 29.4%, and the prevalence of STI was 11.1%. Participants were similar by arm for most factors considered. Participation and follow-up rates were excellent (60.9% and 80.3%). There was no statistically significant difference in uptake of reliable contraception for intervention versus controls at 6 months (1.45 [0.99-2.12]) or 12 months (1.33 [0.92-1.91]). At 6 months, several secondary outcomes were improved/trended toward improvement in intervention compared with control, but this effect waned by 12 months, except for intention to use condoms which remained improved. CONCLUSION AND RELEVANCE: The intervention was efficacious for increasing some self-reported UTP and STI prevention behaviors, which waned over time, and the intervention had minimal impact on STI or pregnancy rates suggesting that this type of online intervention may need additional components.

RESUMO

Prior to the SARS-CoV-2 pandemic, antibiotic resistance was listed as the major global health care priority. Some analyses, including the O'Neill report, have predicted that deaths due to drug-resistant bacterial infections may eclipse the total number of cancer deaths by 2050. Although fungal infections remain in the shadow of public awareness, total attributable annual deaths are similar to, or exceeds, global mortalities due to malaria, tuberculosis or HIV. The impact of fungal infections has been exacerbated by the steady rise of antifungal drug resistant strains and species which reflects the widespread use of antifungals for prophylaxis and therapy, and in the case of azole resistance in Aspergillus, has been linked to the widespread agricultural use of antifungals. This review, based on a workshop hosted by the Medical Research Council and the University of Exeter, illuminates the problem of antifungal resistance and suggests how this growing threat might be mitigated.

RESUMO

Patterns and correlates of substance use among urban African American young women (ages 18-19, n = 459) were examined. Four patterns were identified: no/infrequent alcohol and marijuana use (64.9%); recent alcohol only use (18.2%); recent marijuana only use (7.9%); and recent alcohol and marijuana use (9.0%). Having a recent male sexual partner and a history of sexual coercion were associated with increased odds of marijuana-only and dual use. Greater family support and childhood sexual abuse were associated with increased odds of alcohol-only use. Results suggest that sexual relationships and history of abuse/coercion are important factors in young African American women's substance use.

RESUMO

PURPOSE: To compare the dietary quality among adolescents who skip lunch and those who do not and explore associations between school-level variables, demographic variables and lunch skipping. DESIGN: Cross-sectional. SETTING: Public schools in New Orleans, Louisiana (n = 21). PARTICIPANTS: 718 adolescents. METHODS: Adolescents participated in a 24-hour dietary recall using the Automated Self-Administered 24-Hour (ASA24) Dietary Assessment Tool early in 2013. Data were converted into Healthy Eating Index (HEI-2010) scores. Mean scores were compared between students who skipped lunch and those who did not. A multilevel analysis was conducted to assess relationships between school environment, demographics, and lunch skipping. RESULTS: Of the 718 respondents, 88.3% were Black and 15.3% skipped lunch. Students who ate lunch had a mean HEI score of 46.6 compared to a mean score of 41.7 for students who skipped lunch (p < .001). Students who skipped lunch also had significantly lower intake of total vegetables (p = .02), whole fruits (p < .001), total dairy (p = .003), total protein (p < .001). CONCLUSIONS: Skipping lunch was associated with lower quality diet, though diet quality was low among all students. Considering over 15% of the sample did not eat lunch in a closed-campus school setting, further research should consider how to encourage students to participate in the National School Lunch Program, which has the ability to increase diet quality in adolescents.

RESUMO

Introduction. While school-based kitchen garden programs are shown to improve fruit and vegetable consumption and knowledge among children, there has been little research on participant perceptions of these programs, specifically among minority populations that are disproportionately affected by and at high risk for overweight and obesity. This qualitative study examined the perceptions of and values associated with participation in school-based kitchen garden programs implemented through Edible Schoolyard New Orleans in low-income, predominantly African American schools in New Orleans, Louisiana. Method. Qualitative data were collected through semistructured focus group discussions with key stakeholder groups at schools offering Edible Schoolyard New Orleans. Results. A total of 10 focus groups were conducted across 4 middle schools with students (n = 27), parents (n = 17), and teachers (n = 17). Four primary themes emerged during data analysis: development of life skills, food and health, family and community, and experiential and participatory learning. Conclusions. To strengthen the sustainability and potential impact of school-based kitchen garden programs, future intervention strategies should place specific emphasis on the themes that emerged from this study. School-based kitchen garden programs may be a promising strategy to positively influence the individual, social, and physical environmental factors that contribute to overweight and obesity in low-income, African American communities.

RESUMO

The ability to anticipate and respond appropriately to the challenges and opportunities present in our environments is critical for adaptive behavior. Recent methodological innovations have led to substantial advances in our understanding of the neurocircuitry supporting such motivated behavior in adulthood. However, the neural circuits and cognitive processes that enable threat- and reward-motivated behavior undergo substantive changes over the course of development, and these changes are less well understood. In this article, we highlight recent research in human and animal models demonstrating how developmental changes in prefrontal-subcortical neural circuits give rise to corresponding changes in the processing of threats and rewards from infancy to adulthood. We discuss how these developmental trajectories are altered by experiential factors, such as early-life stress, and highlight the relevance of this research for understanding the developmental onset and treatment of psychiatric disorders characterized by dysregulation of motivated behavior.

RESUMO

Objectives Despite significant investments in Maternal and Child Health (MCH), the United States still lags behind other countries in key MCH indicators. A well-trained workforce is needed to improve MCH. The Division of MCH Workforce Development of HRSA's Maternal and Child Health Bureau provides funding to schools of Public Health to support Centers of Excellence in MCH, which is focused on preparing the next generation of MCH leaders through specialized training and mentorship. One such center, the Tulane Center of Excellence in MCH (CEMCH), is housed at the Tulane University School of Public Health and Tropical Medicine. This study evaluated the perceived effectiveness and acceptability of the CEMCH leadership training program. Methods A mixed-methods approach was used, consisting of semi-structured interviews and quantitative surveys which were analyzed through inductive methods based in grounded theory and non-parametric methods respectively. Results Results indicated an overall high level of program satisfaction by all stakeholders. Mentorship and personal attention emerged as an important benefit for both former and current Scholars. The opportunity to gain real-world understanding of MCH work through program activities was an added benefit, although these activities also presented the most challenges. Community stakeholders generally did not view the program as providing immediate organizational benefit, but recognized the distal benefit of contributing to a well-trained MCH workforce. Conclusions for Practice These results will be used to inform other MCH training programs and strengthen Tulane's CEMCH. A well-trained MCH workforce is essential to improving MCH, and high-quality training its foundation.

RESUMO

Parks can be an important, low-cost neighborhood resource to increase physical activity and reduce overweight and obesity. The quality of parks, however, may impact use. This study used observational data to examine the relationships between park quality, park usage and levels of physical activity among users in 31 parks within low-income, African American neighborhoods. Relationships between park use and park characteristics (signs of disorder, attractiveness, and number of activity settings) varied by gender and user activity level. No variables of interest were significant for overall number of male users; whereas, disorder and attractiveness were significant for overall number of female users. Parks with signs of disorder were associated with 49% fewer female users (IRR = 0.51, 95% CI = (0.34⁻0.77)) and attractive parks with 146% more female users (IRR = 2.46, 95% CI = (1.39⁻4.33)). Similar significant relationships were found among active but not sedentary female users. Communities may consider increasing park maintenance and addressing attractiveness in existing parks as a relatively low-cost environmental strategy to encourage park use, increase physical activity, and reduce the burden of obesity, especially among women in low-income, African-American communities.

RESUMO

BACKGROUND: Little empirical evidence exists on the effectiveness of using Twitter as a two-way communication tool for public health practice, such as Twitter chats. OBJECTIVE: We analyzed whether Twitter chats facilitate engagement in two-way communications between public health entities and their audience. We also describe how to measure two-way communications, incoming and outgoing mentions, between users in a protocol using free and publicly available tools (Symplur, OpenRefine, and Gephi). METHODS: We used a mixed-methods approach, social network analysis, and content analysis. The study population comprised individuals and organizations participating or who were mentioned in the first #LiveFitNOLA chat, during a 75-min period on March 5, 2015, from 12:00 PM to 1:15 PM Central Time. We assessed audience engagement in two-way communications with two metrics: engagement ratio and return on engagement (ROE). RESULTS: The #LiveFitNOLA chat had 744 tweets and 66 participants with an average of 11 tweets per participant. The resulting network had 134 network members and 474 engagements. The engagement ratios and ROEs for the #LiveFitNOLA organizers were 1:1, 40% (13/32) (@TulanePRC) and 2:1, -40% (-25/63) (@FitNOLA). Content analysis showed information sharing (63.9%, 314/491) and health information (27.9%, 137/491) as the most salient theme and sub-theme, respectively. CONCLUSIONS: Our findings suggest Twitter chats facilitate audience engagement in two-way communications between public health entities and their audience. The #LiveFitNOLA organizers' engagement ratios and ROEs indicated a moderate level of engagement with their audience. The practical significance of the engagement ratio and ROE depends on the audience, context, scope, scale, and goal of a Twitter chat or other organized hashtag-based communications on Twitter.

RESUMO

The school lunch salad bar (SB) is a recommended food environmental strategy to increase access to, and consumption of fruit and vegetables (F/V). In a study to examine use of school lunch SBs, middle and high school students provided data via the Automated Self-Administered 24-h dietary recall (24HDR) tool for kids (ASA24-Kids-2012), a web-based data collection platform. Kilocalories were computed, food groups were assigned and F/V sources were obtained. Students (n = 718) from 12 schools with SBs and nine schools without SBs were approximately 87% African American, over 64% female and most were 7th and 8th graders. SB school students had higher median energy consumption at lunch but a higher percent of non-SB students reported eating fruit at lunch compared to SB students. Most students reporting eating F/V at lunch obtained F/V from the cafeteria main line; only 19.6% reported eating F/V exclusively from the SB. In SB schools median intake of cups F/V was higher among students using the SB (0.92) compared to those not using the SB (0.53). Results of this study are mixed, but encouraging. Additional factors, e.g., nutrition education, marketing, and kinds of foods offered on the SB need to be examined for potential influence on SB use.

RESUMO

This study examines how the consumption of fruits and vegetables is affected by home cooking habits and shopping patterns, including distance to patronized stores and frequency of shopping, in two low-income predominantly African American urban neighborhoods in New Orleans, Louisiana. In-person interviews were conducted in 2013 with 901 adult residents who identified themselves as the primary household shopper. Respondents were asked where and how often they shopped and answered a food frequency questionnaire. Addresses were geocoded and distances to the stores where respondents shopped were calculated. Multivariable logistic regression was used to examine the relationship between food consumption and personal factors, neighborhood factors and shopping habits. Consumption of daily servings of fresh produce increased by 3% for each additional trip to a grocery store, by 76% for shopping at a farmer's market, and by 38% for preparing food at home. Each additional trip to a convenience store increased the frequency of consumption of chips, candy and pastries by 3%. The distance from residence to the type of store patronized was not associated with consumption of produce or chips, candy or pastries. Shopping at full-service grocery stores, farmer's markets and cooking at home were positively associated with the consumption of fresh produce while shopping at convenience stores was associated with increased consumption of chips, candy and pastries. These findings are useful for designing programmatic interventions to increase fresh fruit and vegetable consumption among residents in low-income urban communities.

RESUMO

BACKGROUND: Consumption levels of fruits and vegetables (F/V) among children/adolescents are low. Programs like school-based salad bars (SB) provide children/adolescents increased F/V access. AIMS: The purpose of this study was to examine the relationship between SB use and individual and school-level factors among elementary and secondary school students in New Orleans public schools. METHOD: Twelve schools receiving SB units from the Let's Move Salad Bars to Schools Campaign participated in this study. Self-reported data were collected from students ( n = 1,012), administrators ( n = 12), and food service staff ( n = 37). School environmental data were obtained through direct observation. Generalized estimating equation regression methods were used to develop a multilevel model including both school-level (e.g., length of lunchtime, SB marketing, vending machines) and individual-level (e.g., sex, food preferences, nutrition knowledge) effects. RESULTS: Female students had higher odds of using the SB compared to males. Students with healthier food preferences had higher odds of using the SB than those who reported less healthy food preferences. Within the multilevel model for all students, only sex and healthy food preferences remained significant. In a multilevel model assessing secondary students only, student encouragement toward others for healthy eating and school-based SB marketing were significantly related to SB use. CONCLUSIONS: Little research has examined factors related to school-based SB use. These findings suggest recommendations that may help improve student use of SBs. For example, increasing the promotion of SB, particularly in secondary schools, might encourage their use among students.

RESUMO

Postnatal brain development is studded with sensitive periods during which experience dependent plasticity is enhanced. This enables rapid learning from environmental inputs and reorganization of cortical circuits that matches behavior with environmental contingencies. Significant headway has been achieved in characterizing and understanding sensitive period biology in primary sensory cortices, but relatively little is known about sensitive period biology in associative neocortex. One possible mediator is the onset of puberty, which marks the transition to adolescence, when animals shift their behavior toward gaining independence and exploring their social world. Puberty onset correlates with reduced behavioral plasticity in some domains and enhanced plasticity in others, and therefore may drive the transition from juvenile to adolescent brain function. Pubertal onset is also occurring earlier in developed nations, particularly in unserved populations, and earlier puberty is associated with vulnerability for substance use, depression and anxiety. In the present article we review the evidence that supports a causal role for puberty in developmental changes in the function and neurobiology of the associative neocortex. We also propose a model for how pubertal hormones may regulate sensitive period plasticity in associative neocortex. We conclude that the evidence suggests puberty onset may play a causal role in some aspects of associative neocortical development, but that further research that manipulates puberty and measures gonadal hormones is required. We argue that further work of this kind is urgently needed to determine how earlier puberty may negatively impact human health and learning potential. This article is part of a Special Issue entitled SI: Adolescent plasticity.

RESUMO

Rules encompass cue-action-outcome associations used to guide decisions and strategies in a specific context. Subregions of the frontal cortex including the orbitofrontal cortex (OFC) and dorsomedial prefrontal cortex (dmPFC) are implicated in rule learning, although changes in structural connectivity underlying rule learning are poorly understood. We imaged OFC axonal projections to dmPFC during training in a multiple choice foraging task and used a reinforcement learning model to quantify explore-exploit strategy use and prediction error magnitude. Here we show that rule training, but not experience of reward alone, enhances OFC bouton plasticity. Baseline bouton density and gains during training correlate with rule exploitation, while bouton loss correlates with exploration and scales with the magnitude of experienced prediction errors. We conclude that rule learning sculpts frontal cortex interconnectivity and adjusts a thermostat for the explore-exploit balance.

RESUMO

The adolescent transition from juvenile to adult is marked by anatomical and functional remodeling of brain networks. Currently, the cellular and synaptic level changes underlying the adolescent transition are only coarsely understood. Here, we use two-photon imaging to make time-lapse observations of long-range axons that innervate the frontal cortex in the living brain. We labeled cells in the orbitofrontal cortex (OFC) and basolateral amygdala (BLA) and imaged their axonal afferents to the dorsomedial prefrontal cortex (dmPFC). We also imaged the apical dendrites of dmPFC pyramidal neurons. Images were taken daily in separate cohorts of juvenile (P24-P28) and young adult mice (P64-P68), ages where we have previously discovered differences in dmPFC dependent decision-making. Dendritic spines were pruned across this peri-adolescent period, while BLA and OFC afferents followed alternate developmental trajectories. OFC boutons showed no decrease in density, but did show a decrease in daily bouton gain and loss with age. BLA axons showed an increase in both bouton density and daily bouton gain at the later age, suggesting a delayed window of enhanced plasticity. Our findings reveal projection specific maturation of synaptic structures within a single frontal region and suggest that stabilization is a more general characteristic of maturation than pruning.

RESUMO

INTRODUCTION: Argentina and Uruguay have a high prevalence of smoking during pregnancy. However, and despite national recommendations, pregnant women are not routinely receiving cessation counseling during antenatal care (ANC). We evaluated a multifaceted strategy designed to increase the frequency of pregnant women who received a brief smoking cessation counseling based on the 5As (Ask, Advise, Assess, Assist, and Arrange). METHODS: We randomly assigned (1:1) 20 ANC clusters in Buenos Aires, Argentina and Montevideo, Uruguay to receive a multifaceted intervention to implement brief smoking cessation counseling into routine ANC, or to receive no intervention. The primary outcome was the frequency of women who recalled receiving the 5As during ANC at more than one visit. Frequency of women who smoked until the end of pregnancy, and attitudes and readiness of ANC providers towards providing counseling were secondary outcomes. Women's outcomes were measured at baseline and at the end of the 14- to 18-month intervention, by administering questionnaires at the postpartum hospital stay. Self-reported cessation was verified with saliva cotinine. The trial took place between October 03, 2011 and November 29, 2013. RESULTS: The rate of women who recalled receiving the 5As increased from 14.0% to 33.6% in the intervention group (median rate change, 22.1%), and from 10.8% to 17.0% in the control group (median rate change, 4.6%; P = .001 for the difference in change between groups). The effect of the intervention was larger in Argentina than in Uruguay. The proportion of women who continued smoking during pregnancy was unchanged at follow-up in both groups and the relative difference between groups was not statistically significant (ratio of odds ratios 1.16, 95% CI: 0.98-1.37; P = .086). No significant changes were observed in knowledge, attitudes, and self-confidence of ANC providers. CONCLUSIONS: The intervention showed a moderate effect in increasing the proportion of women who recalled receiving the 5As, with a third of women receiving counseling in more than one visit. However, the frequency of women who smoked until the end of the pregnancy was not significantly reduced by the intervention. IMPLICATIONS: No implementation trials of smoking cessation interventions for pregnant women have been carried out in Latin American or in middle-income countries where health care systems or capacities may differ. We evaluated a multifaceted strategy designed to increase the frequency of pregnant women who receive brief smoking cessation counseling based on the 5As in Argentina and Uruguay. We found that the intervention showed a moderate effect in increasing the proportion of women receiving the 5As, with a third of women receiving counseling in more than one visit. However, the frequency of women who smoked until the end of the pregnancy was not significantly reduced by the intervention.

RESUMO

INTRODUCTION: The 5A's (Ask, Advise, Assess, Assist, and Arrange) strategy, a best-practice approach for cessation counseling, has been widely implemented in high-income countries for pregnant women; however, no studies have evaluated implementation in middle-income countries. The study objectives were to assess smoking patterns and receipt of 5A's among pregnant women in Buenos Aires, Argentina and Montevideo, Uruguay. METHODS: Data were collected through administered questionnaires to women at delivery hospitalizations during October 2011-May 2012. Eligible women attended one of 12 maternity hospitals or 21 associated prenatal care clinics. The questionnaire included demographic data, tobacco use/cessation behaviors, and receipt of the 5A's. Self-reported cessation was verified with saliva cotinine. RESULTS: Overall, of 3400 pregnant women, 32.8% smoked at the beginning of pregnancy; 11.9% quit upon learning they were pregnant or later during pregnancy, and 20.9% smoked throughout pregnancy. Smoking prevalence varied by country with 16.1% and 26.7% who smoked throughout pregnancy in Argentina and Uruguay, respectively. Among pregnant smokers in Argentina, 23.8% reported that a provider asked them about smoking at more than one prenatal care visit; 18.5% were advised to quit; 5.3% were assessed for readiness to quit, 4.7% were provided assistance, and 0.7% reported follow-up was arranged. In Uruguay, those percentages were 36.3%, 27.9%, 5.4%, 5.6%, and 0.2%, respectively. CONCLUSIONS: Approximately, one in six pregnant women smoked throughout pregnancy in Buenos Aires and one in four in Montevideo. However, a low percentage of smokers received any cessation assistance in both countries. Healthcare providers are not fully implementing the recommended 5A's intervention to help pregnant women quit smoking.

RESUMO

BACKGROUND: Childhood obesity continues to be a public health problem in the United States. Increasing consumption of fruits and vegetables (F/V) is one strategy for decreasing high consumption of energy-dense, high-fat foods, thereby improving weight status. Many Orleans Parish public schools were provided with salad bars (SBs) to augment school lunch with increased access to F/V. This study identified factors associated with student use of SBs. METHODS: Surveys examining SB use, demographics, food preference, nutrition knowledge, and social support were administered to students in the 7th to 12th grades (N = 702) in Orleans Parish (New Orleans, Louisiana). Generalized estimating equations, which incorporate clustering at the school level, helped to determine associations between independent variables and SB use. RESULTS: Sixty percent of participants were SB users. Non-African-American students were more likely to be SB users than African-American students (odds ratio [OR] = 2.35, confidence interval [CI]: 1.35-4.07) and students who had high preference for healthy food were more likely to use the SB than those who had low preference (OR = 2.41, CI: 1.44-4.01). Students who encouraged others to consume F/V were more likely to use the SB than those who did not (p = .015). CONCLUSIONS: Individual and interpersonal factors related to SB use can provide guidance in the development of school-based interventions to increase SB use and F/V consumption.
