"The Phone is my Lifeline": Use of Mobile Phone Technology to Support Recovery among Individuals in Treatment for Substance Use Disorders.

Background: People experiencing substance use disorders (SUD) face myriad challenges in maintaining changes in substance use after treatment. Mobile phones can play a role in supporting the recovery process. To date, research has not explored how individuals use mobile phones to seek social support as they enter SUD recovery. Objectives: We sought to understand how individuals in SUD treatment use mobile technology in support of their recovery. Methods: We conducted semi-structured interviews with thirty individuals in treatment for any SUD in northeastern Georgia and southcentral Connecticut. Interviews explored participants' attitudes toward mobile technology and how they used mobile technology while using substances, in treatment, and in recovery. Qualitative data were coded and analyzed using thematic analysis. Results: We identified three major themes related to how participants: (1) adapted their use of mobile technology as they entered recovery, (2) relied on mobile technology for social support while in recovery, while (3) some found aspects of mobile technology triggering. Many individuals in SUD treatment reported using mobile phones to buy or sell drugs; as such, they took measures to adapt their use of mobile technology as they changed substance use behaviors. As they entered recovery, individuals relied on mobile phones for affiliational, emotional, informational, and instrumental support, though some did share they found some aspects of mobile phones triggering. Conclusion: These findings highlight the importance of treatment providers engaging in conversations around mobile phone use to help individuals avoid triggers and connect with social supports. These findings uncover new opportunities for recovery support interventions utilizing mobile phones as a delivery mechanism.

Development of a Multi-Level Family Planning Intervention for Couples in Rural Uganda: Key Findings & Adaptations Made from Community Engaged Research Methods.

Background: Uganda has among the highest fertility rates in the world and multi-level barriers contribute to the low contraceptive use. Objective: The objective of this study was to develop a culturally and socially relevant, community-based intervention to increase contraceptive use among couples in rural Uganda through community-engaged research methods. This study reports on the community-engaged research that informed the intervention's content and structure and the final content of the intervention; the evaluation of the pilot intervention will be reported upon completion. Methods: An intervention steering committee of community stakeholders reviewed the initially proposed intervention content and approach. Focus groups were conducted with men and women separately (N=26) who had unmet need for family planning. Fifteen key-informant interviews were conducted with community leaders and family planning stakeholders. Finally, the 4-session intervention was pilot tested with a cohort of couples (N=7) similar in demographics to the target sample of the future pilot intervention trial. Qualitative data were analyzed thematically. Results: Findings included the identification of community beliefs to reshape to increase family planning acceptance, as well as strategies to engage men, acceptable approaches for community leader involvement in the intervention to endorse family planning, and methods for managing gender dynamics and minimizing risk of unintended negative consequences of participation. The findings were used to shape the ideal structure and format of the intervention, including the distribution of contraceptives directly during group sessions, and identified the need to strengthen health worker capacity to provide Long-Acting Reversable Contraceptives (LARCs) as part of the intervention. Conclusions: These findings were used to refine an intervention before a larger scale pilot test of its feasibility, acceptability, and potential efficacy. They can inform other multi-level family planning interventions in similar settings and the methods can be adopted by others to increase the feasibility, acceptability, and cultural relevance of interventions.

Protocol for the pilot quasi-experimental controlled trial of a gender-responsive implementation strategy with providers to improve HIV outcomes in Uganda.

BACKGROUND: Antiretroviral treatment (ART) is the most effective clinical intervention for reducing morbidity and mortality among persons living with HIV. However, in Uganda, there are disparities between men and women in viral load suppression and related HIV care engagement outcomes, which suggests problems with the implementation of ART. Gender norms are a known driver of HIV disparities in sub-Saharan Africa, and patient-provider relationships are a key factor in HIV care engagement; therefore, the role of gender norms is important to consider in interventions to achieve the equitable provision of treatment and the quality of ART counseling. METHODS: The overall research objective of this study is to pilot test an implementation strategy (i.e., methods to improve the implementation of an evidence-based intervention) to increase providers' capacity to provide gender-responsive treatment and counseling to men and women on HIV treatment in Uganda. Delivered to HIV providers, this group training adapts evidence-based strategies to reduce gender biases and increase skills to deliver gender-specific and transformative HIV counseling to patients. The implementation strategy will be piloted through a quasi-experimental controlled trial. Clinics will be randomly assigned to either the intervention or control conditions. The trial will assess feasibility and acceptability and explore barriers and facilitators to implementation and future adoption while gathering preliminary evidence on the implementation strategy's effectiveness by comparing changes in patient (N = 240) and provider (N = 80-140) outcomes across intervention and control clinics through 12-month follow-up. Quantitative data will be descriptively analyzed, qualitative data will be analyzed through thematic analysis, and these data will be mixed during the presentation and interpretation of results where appropriate. DISCUSSION: This pilot intervention trial will gather preliminary evidence on the acceptability, feasibility, and potential effect of a novel implementation strategy to improve men and women's HIV care engagement, with the potential to reduce gender disparities in HIV outcomes.

The use of multiple hypothesis-generating methods in an outbreak investigation of Escherichia coli O121 infections associated with wheat flour, Canada 2016-2017.

A Canadian outbreak investigation into a cluster of Escherichia coli O121 was initiated in late 2016. When initial interviews using a closed-ended hypothesis-generating questionnaire did not point to a common source, cases were centrally re-interviewed using an open-ended approach. The open-ended interviews led cases to describe exposures with greater specificity, as well as food preparation activities. Data collected supported hypothesis generation, particularly with respect to flour exposures. In March 2017, an open sample of Brand X flour from a case home, and a closed sample collected at retail of the same brand and production date, tested positive for the outbreak strain of E. coli O121. In total, 76% (16/21) of cases reported that they used or probably used Brand X flour or that it was used or probably was used in the home during their exposure period. Crucial hypothesis-generating techniques used during the course of the investigation included a centralised open-ended interviewing approach and product sampling from case homes. This was the first outbreak investigation in Canada to identify flour as the source of infection.

A review of the impact of blue space on the urban microclimate.

The urban heat island (UHI) phenomenon represents a major public health issue and has received great attention due to rapid urbanisation. Blue spaces have long been considered a possible mitigation strategy to ameliorate the UHI. However, our knowledge regarding the interaction of waterbodies with their urban surroundings is still limited. This review attempts through a comparative analysis of the available literature to examine the thermal effects of static blue spaces on the urban climate. Remote sensing studies are the most common approach analysed in this review but there is a clear disparity between the cooling potentials reported by remote sensing as opposed to field measurements or numerical simulations, likely due to a lack of nocturnal measurements, when warming due to thermal inertia can occur and consideration of the latent heat flux. The size and shape of blue spaces are shown to be important variables for the cooling achieved in urban settings but there is no consensus in the literature. This is likely due to the different locations and climates of the studies, it can be hypothesised that in locations with an even distribution of wind directions a rounder waterbody is more effective while in locations where wind direction is more uniform an elongated waterbody aligned to the wind is more effective due to the increased fetch. From the analysis of the literature, it is clear that there is still a distinct knowledge gap regarding the physical interpretation of waterbodies' contribution to the urban climate. There is also a current lack of information about the diurnal and seasonal variability of the various structures and processes. There is evidence, however, that the comfort achieved by sensible cooling can be offset by the increased water vapour content and that during the night blue spaces may actually exacerbate the UHI, reducing urban thermal comfort.

An outbreak of hepatitis A in Canada: The use of a control bank to conduct a case-control study.

An outbreak of 18 cases of hepatitis A virus infection across five Canadian provinces was investigated. Case onsets occurred between October 2017 and May 2018. A retrospective matched case-control study was conducted to identify the likely source of the outbreak. Three matched controls were recruited for each case using a previously established control bank, supplemented by landline and cell phone call lists. Univariate and multivariate matched analyses were conducted to identify a potential outbreak source. Seventy-two per cent of controls were recruited through the control bank, and required on average 25.5 calls per recruited control; 20% of controls were recruited through a landline sample and 8% of controls were recruited through a cell phone sample, requiring an average of 847.3 and 331.7 calls per recruited control, respectively. Results of the analysis pointed to shrimp/prawns (odds ratio (OR) 15.75, p = 0.01) and blackberries (OR 7.21, p = 0.02) as foods of interest, however, an outbreak source could not be confirmed. The control bank proved to be a more efficient method for control recruitment than random call lists. Expanding the control bank size and using alternative methods, such as online surveys, may prove beneficial for increasing the timeliness of a case-control study during an outbreak investigation.

Methods for generating hypotheses in human enteric illness outbreak investigations: a scoping review of the evidence.

Enteric illness outbreaks are complex events, therefore, outbreak investigators use many different hypothesis generation methods depending on the situation. This scoping review was conducted to describe methods used to generate a hypothesis during enteric illness outbreak investigations. The search included five databases and grey literature for articles published between 1 January 2000 and 2 May 2015. Relevance screening and article characterisation were conducted by two independent reviewers using pretested forms. There were 903 outbreaks that described hypothesis generation methods and 33 papers which focused on the evaluation of hypothesis generation methods. Common hypothesis generation methods described are analytic studies (64.8%), descriptive epidemiology (33.7%), food or environmental sampling (32.8%) and facility inspections (27.9%). The least common methods included the use of a single interviewer (0.4%) and investigation of outliers (0.4%). Most studies reported using two or more methods to generate hypotheses (81.2%), with 29.2% of studies reporting using four or more. The use of multiple different hypothesis generation methods both within and between outbreaks highlights the complexity of enteric illness outbreak investigations. Future research should examine the effectiveness of each method and the contexts for which each is most effective in efficiently leading to source identification.

Utilising green and bluespace to mitigate urban heat island intensity.

It has long been recognised that cities exhibit their own microclimate and are typically warmer than the surrounding rural areas. This 'mesoscale' influence is known as the urban heat island (UHI) effect and results largely from modification of surface properties leading to greater absorption of solar radiation, reduced convective cooling and lower water evaporation rates. Cities typically contain less vegetation and bodies of water than rural areas, and existing green and bluespace is often under threat from increasing population densities. This paper presents a meta-analysis of the key ways in which green and bluespace affect both urban canopy- and boundary-layer temperatures, examined from the perspectives of city-planning, urban climatology and climate science. The analysis suggests that the evapotranspiration-based cooling influence of both green and bluespace is primarily relevant for urban canopy-layer conditions, and that tree-dominated greenspace offers the greatest heat stress relief when it is most needed. However, the magnitude and transport of cooling experienced depends on size, spread, and geometry of greenspaces, with some solitary large parks found to offer minimal boundary-layer cooling. Contribution to cooling at the scale of the urban boundary-layer climate is attributed mainly to greenspace increasing surface roughness and thereby improving convection efficiency rather than evaporation. Although bluespace cooling and transport during the day can be substantial, nocturnal warming is highlighted as likely when conditions are most oppressive. However, when both features are employed together they can offer many synergistic ecosystem benefits including cooling. The ways in which green and bluespace infrastructure is applied in future urban growth strategies, particularly in countries expected to experience rapid urbanisation, warrants greater consideration in urban planning policy to mitigate the adverse effects of the UHI and enhance climate resilience.

Prenatal Depressive Symptoms and Postpartum Sexual Risk Among Young Urban Women of Color.

STUDY OBJECTIVE: To determine whether prenatal depressive symptoms are associated with postpartum sexual risk among young, urban women of color. DESIGN: Participants completed surveys during their second trimester of pregnancy and at 1 year postpartum. Depressive symptoms were measured using the Center for Epidemiologic Studies-Depression Scale, excluding somatic items because women were pregnant. Logistic and linear regression models adjusted for known predictors of sexual risk and baseline outcome variables were used to assess whether prenatal depressive symptoms make an independent contribution to sexual risk over time. SETTING: Fourteen community health centers and hospitals in New York City. PARTICIPANTS: The participants included 757 predominantly black and Latina (91%, n = 692) pregnant teens and young women aged 14-21 years. INTERVENTIONS AND MAIN OUTCOME MEASURES: The main outcome measures were number of sex partners, condom use, exposure to high-risk sex partners, diagnosis of a sexually transmitted disease, and repeat pregnancy. RESULTS: High levels of prenatal depressive symptoms were significantly associated with increased number of sex partners (ß = 0.17; standard error, 0.08), decreased condom use (ß = -7.16; standard error, 3.08), and greater likelihood of having had sex with a high-risk partner (odds ratio = 1.84; 95% confidence interval, 1.26-2.70), and repeat pregnancy (odds ratio = 1.72; 95% confidence interval, 1.09-2.72), among participants who were sexually active (all P < .05). Prenatal depressive symptoms were not associated with whether participants engaged in postpartum sexual activity or sexually transmitted disease incidence. CONCLUSION: Screening and treatment for depression should be available routinely to women at risk for antenatal depression.

Outbreak of measles in a non-immunizing population, Alberta 2013.

BACKGROUND: An outbreak of measles was declared in southern Alberta on October 18, 2013, after a case had been reported to the local public health unit in a non-immunized teenager with recent travel to the Netherlands. The teenager had had contact with a large number of unimmunized people while infectious; therefore, the risk of spread was high. The potential for an outbreak of measles in this area had been identified by the lead Medical Officer of Health for South Zone, and planning for an outbreak had begun in August 2013. METHODS: Several public health measures were implemented to control the outbreak: mass immunization clinics; an outbreak dose of measles mumps and rubella (MMR) vaccine for infants 6-12 months old; communication within the affected and surrounding communities; a dedicated measles hotline; a Mobile Measles Assessment Team; and a Measles Assessment Centre. RESULTS: A total of 42 confirmed cases were identified during the outbreak between October 16 and November 25. Just over half the cases were male (52.4%). The average age was 12 (range < 1 to 24 years) and the median age 13 years. There was one hospitalization, and no deaths occurred. All cases were unimmunized. Cases were located in five communities immediately surrounding Lethbridge. All but two cases were epidemiologically linked within 10 households. CONCLUSION: The planning that occurred before the outbreak was essential in containing the outbreak to 10 households. To prevent future outbreaks of measles, exploring strategies for increasing immunization coverage rates in unimmunized populations is essential. When immunization acceptance is not uniform, other public health strategies should be planned for and implemented in order to prevent additional spread.

Kidney allograft survival of African American and Caucasian American recipients with lupus.

BACKGROUND: African Americans with lupus who receive kidney transplants have high prevalence of predictors of allograft failure, which can explain their poor outcomes. METHODS: Of 1223 African Americans and 1029 Caucasian Americans with lupus who received kidney transplants from deceased donors between 1987 and 2006 with complete records in the UNOS program, 741 pairs were matched in 16 predictors employing a predicted probability of group membership. The primary outcome was allograft failure. Main secondary outcomes were rejection, allograft failure due to rejection, and mortality. RESULTS: Matched pairs were predominantly women (82%) with a mean age of 39 years. Twenty-four percent of recipients received kidneys from expanded criteria donors. African Americans and Caucasian Americans matched well (p ≥ 0.05): donor age, gender and race; recipient age, gender, education and insurance; dialysis prior to transplant, kidneys from expanded criteria donors, cold ischemia time, history of prior kidney transplant, panel reactive antibodies, human leukocyte antigens mismatch, blood type compatibility, transplant Era, and follow-up time. Contrary to the unmatched cohort with significantly higher allograft failure rate (events per 100 patient-years) in African Americans compared to Caucasian Americans (10.49 vs 6.18, p<0.001), matched pairs had similar allograft failure rates (8.41 vs 7.81, p=0.418). Matched pairs also had similar rates of rejections (9.82 vs 9.39, p=0.602), allograft failure due to rejection (6.19 vs 5.71, p=0.453), and mortality (2.79 vs 3.52, p=0.097). CONCLUSION: In lupus recipients of kidney transplants from deceased donors, African American and Caucasian Americans have similar allograft failure rates when predictors are matched between groups.

Hypertensive disease in pregnancy: an examination of ethnic differences and the Hispanic paradox.

OBJECTIVE: The "Hispanic paradox" refers to the epidemiological finding that Hispanics in the US have better health outcomes than the average population despite what their aggregate socioeconomic determinants would predict. The aim of this study was to evaluate obstetric outcomes for a multiethnic population with hypertensive diseases. METHODS: We performed a retrospective review of parturients with hypertensive disease delivering at Duke University Medical Center. We analyzed maternal sociodemographic characteristics and ethnic differences in hypertensive disease types using Chi Square tests. RESULTS: A total of 3,124 women delivered during a period of one year; 9% of them had hypertensive diseases in pregnancy. Gestational hypertension was more commonly diagnosed in Whites, whereas chronic hypertension and mild preeclampsia were more frequently encountered in Blacks and Hispanics respectively (Chi-square = 39.11, p < 0.001). The overall incidence of preeclampsia was less in Hispanics. However, severe preeclampsia rates were equal across groups. Hispanics were more likely to be uninsured and younger, enter prenatal care later, and least likely to complete high school. There was no significant difference in smoking or parity. Stratified analyses by ethnicity showed that the relationship between severe preeclampsia and comorbidities (intrauterine growth restriction, low birth weight, and need for admission to intensive care nursery) were least pronounced in Hispanics and strongest in Black women. CONCLUSION: Despite similar rates of severe preeclampsia and adverse sociodemographic characteristics, Hispanic women with severe preeclampsia had better pregnancy outcomes than Black or White women with the disease.

Deprivation and food access and balance in Saskatoon, Saskatchewan.

INTRODUCTION: We explored food access and balance in Saskatoon, Saskatchewan, Canada in relation to material and social deprivation. METHODS: We mapped the location of all large supermarkets and fast food retailers in Saskatoon. Supermarket accessibility index scores and food balance scores were compared to material and social deprivation indexes to determine significant associations. RESULTS: Our results indicate that the poorest access to supermarkets occurred in areas west of the South Saskatchewan River and also in suburban areas around the perimeter of the city. Areas west of the river are some of the most deprived areas in the city. Saskatoon's mean food balance ratio of 2.3 indicates that access favours fast food. However, we did not find a clear pattern or clear socio-economic gradient for most measures. CONCLUSION: This study highlights the importance of contextual studies of food access. This study also highlighted a number of other issues that should be explored in the Saskatoon context such as individual-level food consumption patterns, mobility, temporal dimensions of food access and economic access as well as interventions that could improve food access in the city.

TITLE: Défavorisation, accès aux aliments et équilibre alimentaire à Saskatoon (Saskatchewan). INTRODUCTION: Nous avons étudié l'accès aux aliments et l'équilibre alimentaire à Saskatoon (Saskatchewan, Canada) en lien avec la défavorisation matérielle et sociale. MÉTHODOLOGIE: Nous avons déterminé l'emplacement de tous les grands supermarchés et des restaurants minute à Saskatoon. L'indice d'accessibilité aux supermarchés et celui de l'équilibre alimentaire ont été comparés aux indices de défavorisation matérielle et sociale afin de déterminer s'il y avait une association importante. RÉSULTATS: Les endroits où il y a le moins de supermarchés sont les quartiers situés à l'ouest de la rivière Saskatchewan Sud ainsi que la banlieue entourant la ville. Les quartiers de l'ouest de la rivière sont les plus défavorisés de la ville. Le ratio moyen de l'équilibre alimentaire de Saskatoon est de 2,3, ce qui indique une prédominance de l'accès aux restaurants-minute. Cependant, nous n'avons pas trouvé de schéma ou de gradient socioéconomique clairs pour plusieurs des indicateurs. CONCLUSION: L'étude souligne l'importance des études contextuelles sur l'accès aux aliments. L'étude met également en lumière un certain nombre d'autres questions qui devraient être étudiées à Saskatoon, comme les habitudes alimentaires individuelles, la mobilité, l'évolution dans le temps de l'accès aux aliments, l'accès économique ainsi que les interventions susceptibles d'améliorer l'accès aux aliments dans la ville.

OS028. Hypertensive disease in pregnancy: An examination of ethnic differences and the Hispanic paradox.

INTRODUCTION: The "Hispanic Paradox" refers to the epidemiological finding that Hispanics in the US have better health outcomes than the average population despite what their aggregate socioeconomic determinants would predict. OBJECTIVES: The aim of this study was to evaluate obstetric outcomes for a multiethnic population with hypertensive diseases. METHODS: We performed a retrospective review of parturients with hypertensive disease delivering at Duke University Medical Center in 2005-2007. We analyzed maternal sociodemographic characteristics and ethnic differences in hypertensive disease types using Chi Square. We assessed the role of race and ethnicity on maternal and neonatal outcomes through a series of logistic regression analyses. RESULTS: Nine thousand eight hundred and thirteen women delivered during the study period, and 9% had hypertensive diseases in pregnancy. There were significant racial and ethnic differences in presentation (Chi-square=39.11, p<.001) with gestational hypertension more common in Whites, chronic hypertension in African Americans, and mild preeclampsia in Hispanics. The overall incidence of preeclampsia was lower in Hispanics. However, severe preeclampsia rates were equal across groups. Hispanics were more likely to be uninsured, younger, enter prenatal care later, and least likely to complete high school. There was no significant difference in smoking or parity. Stratified analyses by ethnicity showed that the relationship between severe preeclampsia and comorbidities (IUGR, LBW, ICN admission) were least pronounced in Hispanics and strongest in African American women. CONCLUSION: Despite similar rates of severe preeclampsia and adverse sociodemographic characteristics, Hispanic women with severe preeclampsia had better pregnancy outcomes than African-American or White women with the disease.

Predictors of HIV/AIDS confirmation and differences by guardian status in HIV+ adolescents in Jamaica / Predictores de la confirmación del VIH/SIDA y diferencias con respecto al estatus de tutoría de adolescentes con VIH+

BACKGROUND: Approximately 25% of the cumulative AIDS cases in Jamaica involve adolescents and young adults. However, the lives of adolescents living with HIV within Jamaica and the Caribbean have been understudied. OBJECTIVES: (1) To describe the sociodemographic characteristics of HIV+ Jamaican adolescents who have ever been a part of the Kingston Paediatric/Perinatal HIV Programme (KPAIDS) from September 1, 2002 to August 31, 2006 (2). To identify predictors of HIV/AIDS confirmation as well as factors associated or uniquely present in these adolescents by their guardian status. METHODS: Seventy-two HIV+ adolescents, ages 10-19 years, were included. Factors studied included demographics as well as time to and time between HIV and AIDS confirmation. Data were analyzed by bivariate and multivariate statistics. RESULTS: The mean age of the adolescents was 12.6 ± 2.8 years with slightly more males (52.8%) in the programme. There were equal proportions of adolescents living with HIV as with AIDS (43.1%). There were equal proportions who were lost to follow-up or deceased (8.3%). Twenty-two of them lived with parents, 25 with guardians and 18 in residential institutions. The primary mode of transmission was perinatal infection (68.1%), followed by sexual (20.8%), blood transfusion (2.9%) and unknown (8.3%). The mean time from HIV exposure to HIV confirmation and AIDS confirmation in mother-to-child transmission (MTCT) cases were 8.0 ± 2.9 years and 9.6 ± 3.3 years, respectively. In the multivariate analysis model, age and gender were significant in predicting time from HIV exposure to HIV confirmation. CONCLUSION: The majority of HIV-positive adolescents reside with parents and guardians and this might indicate support in spite of stigma and discrimination. However, the mean time to HIV confirmation in MTCT cases is quite long and must be reduced.

ANTECEDENTES: Aproximadamente el 25% de los casos cumulativos de SIDA en Jamaica comprenden adolescentes y adultos jóvenes. Sin embargo, las vidas de los adolescentes que viven con VIH en Jamaica y el Caribe no ha recibido suficiente estudio. OBJETIVOS: (1) Describir las características socio-demográficas de los adolescentes jamaicanos VIH+ que hayan sido alguna vez parte del Programa Pediátrico/Prenatal de Kingston contra el SIDA (KPAIDS) desde septiembre 1 de 2002 a agosto 31 de 2006. (2). Identificar los predictores de la confirmación del VIH/SIDA así como los factores asociados o presentes de forma única en estos adolescentes con respecto a su estatus de tutoría. MÉTODOS: Se incluyeron setenta y dos adolescentes VIH+, con edades de 10 a 19 años. Los factores estudiados comprendieron los datos demográficos así como el tiempo hasta la confirmación de VIH y el SIDA, así como el tiempo entre la confirmación de ambos. Los datos fueron analizados mediante estadísticas divariadas y multivariadas. RESULTADOS: La edad promedio de los adolescentes fue 12.6 ± 2.8 años siendo el número de varones ligeramente mayor (52.8%) en el programa. Las proporciones de adolescentes viviendo con VIH fueron iguales a las de los adolescentes viviendo con SIDA (43.1%). Hubo iguales proporciones perdidas al seguimiento o fallecidas (8.3%). Veintidós de ellos vivían con sus padres, 25 con tutores, y 18 en instituciones residenciales. El modo primario de transmisión fue la infección perinatal (68.1%), seguida por la sexual (20.8%), la transfusión de sangre (2.9%), y otros desconocidos (8.3%). Los tiempos medios desde la exposición al VIH hasta la confirmación de VIH y la confirmación del SIDA en los casos de transmisión madre a hijo (TMAH) fueron 8.0 ± 2.9 años y 9.6 ± 3.3 años, respectivamente. En el modelo de análisis multivariado, la edad y el género fueron significativos a la hora de predecir el tiempo desde la exposición al VIH hasta la confirmación del VIH. CONCLUSIÓN: La mayor parte de los adolescentes VIH positivos residen con sus padres y tutores y esto podría ser un índice de apoyo a pesar del estigma y la discriminación. Sin embargo, el tiempo medio hasta la confirmación del VIH en los casos de TMAH es bien largo y tiene que ser reducido.

Knowledge of sex partner treatment for past bacterial STI and risk of current STI.

OBJECTIVES: Effective partner management is critical in reducing the spread of bacterial sexually transmitted infections (STIs). The purpose of this study was to determine the relation between knowledge of partner treatment for a past STI and current infection in the index patient. METHODS: In a cross sectional analysis, 97 adolescent females sampled from community based health clinics reported that they had a past diagnosis of chlamydia or gonorrhoea in structured, face to face interviews. At the time of the interview, adolescents were also tested for chlamydia and gonorrhoea using urine based ligase chain reaction testing. RESULTS: 66% of the adolescents reported knowing that their partner was treated for the past infection. Those who knew their partner was treated were less likely to have a current infection, compared to those who did not know (11% v 30%, adjusted odds ratio and 95% confidence interval 4.46 (1.41 to 14.29), p<0.05). Correlates of not knowing the sex partner was treated included younger age and being in new sex partnership. CONCLUSIONS: Efforts to encourage young women to follow up directly with their partners regarding treatment may help to reduce repeat infections and further spread. Furthermore, alternative strategies such as patient delivered therapy may help with partner treatment in this vulnerable population.

High postpartum rates of sexually transmitted infections among teens: pregnancy as a window of opportunity for prevention.

OBJECTIVES: To identify incidence and predictors of Chlamydia trachomatis and Neisseria gonorrhoeae among postpartum adolescents. These estimates are compared to similar estimates among a cohort of non-pregnant, sexually active teens. METHODS: 203 pregnant and 208 non-pregnant adolescents aged 14-19 years were recruited from 10 community based health clinics in Connecticut, United States. Structured interviews and sexually transmitted infection (STI) testing using ligase chain reaction (LCR) were conducted at a baseline visit (during the third trimester for the pregnant adolescents), and at 6 and 12 month follow up visits (3 and 9 months post partum, for those pregnant at baseline). RESULTS: Among pregnant teens, new infections of C trachomatis and N gonorrhoeae increased from 7.1% at the 6 month follow up interview to 14.3% at the 12 month follow up interview; among non-pregnant teens, new infections remained relatively stable over the 6 and 12 month follow up interviews (9.0% to 8.3%) (group by time interaction, p = 0.005). C trachomatis and N gonorrhoeae prevalence was 1.9 times higher (95% CI: 0.97 to 3.89, p = 0.06) among teens in the late postpartum follow up compared to the non-pregnant teens, controlling for baseline STIs. Predictors of postpartum STIs included having a new partner and number of partners per year of sexual activity. CONCLUSIONS: Postpartum adolescents are vulnerable to STIs. Routine prenatal and postpartum care provide unique opportunities to promote condom use and other risk reduction interventions among adolescents. If sustained post partum, long term reproductive health can be promoted.

Adolescent women underestimate their susceptibility to sexually transmitted infections.

OBJECTIVES: Adolescent females are at significant risk for sexually transmitted infections (STI) and may not accurately incorporate indicators of risk into their perceptions of susceptibility. The objectives of the current analyses were to: (1) examine the relation between perceived susceptibility and indicators of risk; and (2) investigate the relation between perceived susceptibility and actual STI diagnosis. METHODS: Participants were 209 sexually active adolescent females. Indicators of STI risk included STI history, recent symptoms, and sexual risk behaviour (that is, recent unprotected sex and numbers of sexual partners). Chlamydia and gonorrhoea infection were assessed at baseline, 6, and 12 months post-baseline using urine based ligase chain reaction testing. RESULTS: Most participants perceived little or no chance that they would be diagnosed with an STI in the following year. There was no relation between almost all STI indicators and perceptions of susceptibility. Among those receiving a positive chlamydia or gonorrhoea test (n=49) at baseline or in the year following, almost all (81.3%) had perceived themselves to be at little or no risk. CONCLUSION: The adolescent females in this sample did not accurately perceive their susceptibility to STI. They must be enabled to more effectively assess and modify their risk.

Documenting patterns of nursing interventions using cluster analysis.

Use of inferential statistics in research applications of the Nursing Intervention Classification has been rare, yet use of these statistical techniques is needed to answer questions related to intervention patterns. Using data from a descriptive study of 3,733 visits documented by 19 adult nurse practitioner students, hierarchical agglomerative cluster analysis was used to determine whether meaningful nursing intervention patterns could be depicted. Eight intervention clusters were derived, replicated, and validated. Clusters of intervention classes differed in the type of nursing and medical diagnosis, amount of time the nurse spent during the visit, cost of visit, and the age of the patient. Clustering supported the utility of standardized nursing diagnosis and intervention typologies to identify actual practice patterns of adult nurse practitioner students. Cluster analysis is a valuable data analysis strategy when analyzing multiple related variables.
