Abstract
OBJECTIVES To evaluate a preventative behavioral intervention for managing early childhood caries (ECC) in a cohort of high-risk children. METHODS This pragmatic trial of the MySmileBuddy Program (MSB) evaluated preventive behavioral outcomes in a 1-y community health worker-delivered intervention to prevent ECC progression. Pre-/postintervention surveys assessed parent-reported child engagement in therapeutic toothbrushing (i.e., adult-assisted brushing with fluoridated toothpaste twice daily) and caries-related dietary behaviors and barriers. Generalized linear model with identity link for continuous variables and logit link for dichotomous outcomes evaluated pre-/postintervention comparisons and generalized estimating equations accounted for within-participant correlation (α = 0.05). RESULTS Among 1,130 children with postintervention data, the average age was 3.97 y, 99% were Medicaid insured, and 88% were Hispanic. Most parents (95%) were mothers/grandmothers, married or in a committed partnership (75%), unemployed (62%), and with modest education (80% high school degree or less). The odds of reported therapeutic brushing nearly doubled (n = 864; odds ratio [OR] = 1.79, 95% confidence interval [CI] = 1.46, 2.20, P < 0.001); day and night bottle/sippy cup frequencies dropped 0.29 units (n = 871; 95% CI = -0.37, -0.33, P < 0.001) and 0.22 units (n = 1,130; 95% CI = -0.30, -0.15, P < 0.001); nighttime breastfeeding reduced 0.15 units (n = 870; 95% CI = -0.21, -0.10, P < 0.001); sharing utensils reduced 0.30 units (n = 572; 95% CI = -0.39, -0.21, P < 0.001); not using sugary foods to calm child improved 0.37 units (n = 664; 95% CI = 0.31, 0.44, P < 0.001); odds of eating meals and snacks at a table increased (n = 572; OR = 1.57, 95% CI = 1.28, 1.93, P < 0.001; n = 572; OR = 1.80, 95% CI = 1.50, 2.15, P < 0.001) respectively; and reducing barriers to behaviors improved 0.38 units for toothbrushing (n = 666; 95% CI = 0.31, 0.44, P < 0.001) and 0.33 units for diet (n = 668; 95% CI = 0.29, 0.38, P < 0.001). CONCLUSION Despite limitations inherent to pragmatic trials, significant behavioral changes suggest that MSB yielded an important salutary impact. Forthcoming mediation analyses will explore causal pathways. Findings support integration of MSB's behavior change program in caries management initiatives. KNOWLEDGE TRANSFER STATEMENT The results of this study can be used by clinicians, public health leaders, and researchers to inform the development and implementation of community-based, preventative behaviorally focused early childhood caries prevention programs. Study findings may enhance the understanding of the impact of behavioral interventions that engage parents of young children and could lead to more effective prevention for populations at high-risk of caries.

Abstract
Tenofovir diphosphate (TVF-DP) can be quantified in red blood cells (RBCs) and dried blood spots (DBS) and can objectively measure ART adherence and predict viral suppression. Data on the association of TFV-DP with viral load are very limited in adolescents and young adults (AYA) living with perinatally-acquired HIV (PHIV), as are data comparing TFV-DP to other measures of ART adherence, such as self-report and unannounced telephone pill count. Viral load and ART adherence (self-report, TFV-DP and unannounced telephone pill count) were assessed and compared among 61 AYAPHIV recruited from an ongoing longitudinal study (CASAH) in New York City.

Abstract
There are an estimated 2.1 million youth less than 15 years of age living with HIV globally (the majority perinatally HIV-infected [PHIV]) and millions more perinatally HIV-exposed uninfected (PHEU) youth who are expected to survive through adolescence and into adulthood. Transitioning from adolescence to young adulthood requires adaptation to more demanding social interactions, academic pressures, and individual responsibilities which place distinct demands on neurocognitive functions. This study examined longitudinal trajectories of neurocognitive test performance in the domains of processing speed (PS), working memory (WM), and executive functioning (EF) among PHIV and demographically similar PHEU from adolescence through young adulthood. Data for this paper come from four time points, spanning approximately 10 years, within the Child and Adolescent Self-Awareness and Health Study (CASAH). Youth age ranged from 15 to 29 years. Longitudinal linear mixed effect models were computed for each test. Few differences in performance were found on tests of EF and WM between PHIV and PHEU youth as they aged, though PHEU youth showed significantly better PS as they aged than PHIV youth. Future research is needed to understand these vulnerable youth's neurocognitive trajectories as a function of HIV infection and -exposure, biological functions and psychosocial stressors.

Abstract
We examined young gay, bisexual, and other men who have sex with men's (YGBMSM) usage patterns of a pre-coital, applicator-administered rectal placebo gel. An ethnically diverse sample of 94 YGBMSM (aged 18-30 years) were asked to insert hydroxyethylcellulose placebo gel rectally before receptive anal intercourse (RAI) and report their gel use through an interactive voice response system (IVRS) across 12 weeks. We used trajectory analyses to characterize participants' use of the rectal gel over the 12 weeks, and examine whether these trajectories varied based on participants' sociodemographic characteristics, sexual behaviors, application and insertion behaviors, and experiences using the placebo gel. A cubic model was the best fit for these longitudinal data, with two distinct trajectories of gel use observed. The first trajectory ('High with Varying Gel Use per Week') represented YGBMSM (N = 38; 40.3%) who reported using the rectal gel on several occasions per week. The second trajectory ('Low and Consistent Gel Use per Week') represented participants (N = 56; 59.7%) who reported a consistent average use of one gel per week. Participants in the High with Varying Gel Use Trajectory reported trying out a greater number of positions when inserting the gel across the 12-weeks than peers in the Low and Consistent Gel Use Trajectory. YGBMSM reporting more RAI occasions during the trial were more likely be present in the High with Varying Gel Use Trajectory than peers in the Low and Consistent Gel Use Trajectory. Future research examining how to facilitate gel application and adherence among YGBMSM is merited.

Abstract
We examined how experiences with a rectal placebo gel and applicator used with receptive anal intercourse (RAI) related to young men who have sex with men's (YMSM) likelihood of using a rectal microbicide gel and applicator in the future. An ethnically diverse sample of 95 YMSM (aged 18 to 30 years) were asked to insert hydroxyethylcellulose (HEC) placebo gel rectally before RAI during 12 weeks and report the product's acceptability (i.e., satisfaction with applicator and gel, respectively; perceived gel side effects; and sexual satisfaction when gel was used) and likelihood of future microbicide use. Main and interaction effects predicting future use intentions were tested using linear regression. We found a positive association between future use intentions and applicator satisfaction (b = .33, p < .001). In a subsequent interaction effects model, we found that greater gel satisfaction was associated with increased future use intentions; however, the strength of this relationship was magnified when YMSM reported greatest satisfaction with the rectal applicator. Applicator satisfaction may be a salient factor in YMSM's decision-making to use a rectal microbicide in the future. Although the importance of developing a satisfactory rectal microbicide gel for YMSM is undeniable for its future use, our results also emphasize the importance of developing strategies that increase YMSM's comfort and skill when using a rectal applicator. Future research examining how to optimize the design, properties, and characteristics of a rectal applicator as a strategy to promote greater satisfaction and use among YMSM is merited.

Abstract
At the time of this writing, no randomized controlled trial (RCT) of an intervention to reduce unsafe sex among Latino gay and bisexual men (LGBM) had been published. We report the results of an RCT conducted in New York City in which 180 LGBM were assigned either to an intervention developed specifically for this population or to a wait-list control group. The intervention was based on empowerment theory and used factors identified in prior research as determinants of unsafe sex. By eligibility criteria, all men had engaged in unprotected anal intercourse (UAI) within two months of the baseline assessment. At first (two months) and second (six months later) follow-up assessments, approximately half of the men in the experimental group reported no UAI. Yet, a similar proportion of the control group also reported no UAI. Baseline data indicate that although the men had been the subject of social oppression and sexual prejudice (homophobia), they did not feel disempowered, externally controlled or fatalistic, and they reported self-efficacy and intentionality to enact safer sex. Lessons learned are discussed, as well as notes of caution for future research employing a similar conceptual framework.

Abstract
BACKGROUND Many reports on Iraq suggest that a rise in rates of death and disease have occurred since the Gulf War of January/February 1991 and the economic sanctions that followed it. METHODS Four preliminary models, based on unadjusted projections, were developed. A logistic regression model was then developed on the basis of six social variables in Iraq and comparable information from countries in the State of the World's Children report. Missing data were estimated for this model by a multiple imputation procedure. The final model depends on three socio-medical indicators: adult literacy, nutritional stunting of children under 5 years, and access to piped water. RESULTS The model successfully predicted both the mortality rate in 1990, under stable conditions, and in 1991, following the Gulf War. For 1996, after 5 years of sanctions and prior to receipt of humanitarian food via the oil for food programme, this model shows mortality among children under 5 to have reached an estimated 87 per 1000, a rate last experienced more than 30 years ago. CONCLUSIONS Accurate and timely estimates of mortality levels in developing countries are costly and require considerable methodological expertise. A rapid estimation technique like the one developed here may be a useful tool for quick and efficient estimation of mortality rates among under 5 year olds in countries where good mortality data are not routinely available. This is especially true for countries with complex humanitarian emergencies where information on mortality changes can guide interventions and the social stability to use standard demographic methods does not exist.

Abstract
Several groups are developing ultra-miniature x-ray machines for clinical use in radiation therapy. Current systems are for interstitial radiosurgery and for intravascular insertion for irradiation to prevent re-stenosis. Typical generating voltages are low, in the 20 to 40 kV range. It is well established that the biological effectiveness of such low-energy photons is large compared with higher-energy gamma rays, because of the dominance of photoelectric absorption at low energies. We have used microdosimetric analyses to estimate RBEs for such devices, both at low doses and clinically relevant doses, relative to radiations from 60Co, 192Ir, 125I and 90Sr/90Y. The RBEs at clinically relevant doses and dose rates for these low-energy x-ray sources are considerably above unity, both relative to 60Co and to 192Ir photons, and also relative to 125I and 90Sr/90Y brachytherapy sources. As a function of depth, the overall effect of the change in dose and the change in beam spectrum results in beams whose biologically weighted dose (dose x RBE) decreases with depth somewhat more slowly than does the physical dose. The estimated clinically relevant RBEs are sufficiently large that they should be taken into account during the treatment design stage.

Abstract
Physicians who have graduated from traditional medical education curriculum focus on technological and organ system training, and are deficient in modern community health care concepts and skills. A preceptorship course integrates at various medical educational periods is one of the important goals at education reform in America. In this study, we attempt to ascertain the opinions of family physicians about the current family medicine curriculum and the practicability of preceptorship in Taiwan. The result can be a reference for future medical curriculum design. Two hundreds and thirty-five (40.8%) questionnaires were collected and analyzed. They showed most respondents were dissatisfied with the current curriculum of family medicine, and most agree that primary care physicians involvement would be helpful in producing efficient and well-qualified physicians. They suggested that preceptorship should best be first integrated in a basic knowledge course. We suggest that faculties who are responsible for curriculum design should evaluate the current curriculum and the appropriateness of preceptorship in Taiwan. Prior to the reform, faculty development and evaluation are the essential and crucial tasks.
