to identify the best strategies for preventing bone loss in bariatric patients receiving RYGB.Limited detection power has been a bottleneck for subject-specific functional MRI (fMRI) studies, however the higher signal-to-noise ratio afforded by ultra-high magnetic fields (≥ 7 Tesla) provides levels of sensitivity and resolution needed to study individual subjects. What may be surprising is that higher imaging resolution may provide both higher specificity and sensitivity due to reductions in partial volume effects and reduced physiological noise. However, challenges remain to ensure high data quality and to reduce variability in ultra-high field fMRI. We discuss session-specific biases including those caused by factors related to instrumentation, anatomy, and physiology-which can translate into variability across sessions-and how to minimize these to help ultra-high field fMRI reach its full potential for individual-focused studies.
Minimally regulated electronic cigarettes (e-cigarette) advertising may be one potential factor driving the increasing prevalence of young adult e-cigarette use. Using eye-tracking, the current study examined which e-cigarette advertising features were the most appealing to young adults as a first step to examine how e-cigarette advertising may be regulated.

Using a within-subjects design, 30 young adults (

= 20.0 years) viewed e-cigarette ads in a laboratory. Ad features or areas of interest (AOIs) included 1) brand logo, 2) product descriptor, and 3) people. During ad viewing, eye-tracking measured participants' dwell time and time to first fixation for each AOI as well as each ad brand. Harm perceptions pre- and post-viewing were measured.

Participants spent the longest dwell time on people (
= 2701 ms), then product descriptors (
= 924 ms), then brand logos (
= 672 ms;
s < .001). They also fixated fastest on AOIs in that order. Participant sex significantly impacted dwell time of ad brand, and harm perceptions decreased after viewing the ads (
s < .05).

This study provides initial evidence about which e-cigarette ad features may appeal most to young adults and may be useful when designing evidence-based policy.

Early infant diagnosis (EID) of HEI and linkage to care reduces morbidity and mortality. There has been limited attention to infants who are lost to follow up despite their mothers being compliant to the PMTCT program. This study explored factors that influence loss-to-follow up among HEI in the EID program whose mothers were retained in care for up to 24 months in Phalombe district, Malawi. NF-κB inhibitor We conducted a descriptive phenomenological qualitative study from May 2017 to July 2018. We purposively conducted 18 in-depth interviews among HIV positive mothers whose HEI were enrolled in the follow-up program and 7 key informant interviews among healthcare workers (HCW). All interviews were digitally recorded, transcribed, and translated verbatim. Data were analyzed manually using a thematic step-by-step approach. Results showed that retention in care is facilitated by aspirations to have a healthy infant and linkage to a nearer facility to a mother's place of residency. The barriers to retention were non-disclosure of HIV status, inadequate resources, and support, suboptimal guidelines for, a lack of privacy, and unsynchronized hospital visits between a mother and her baby. The study has shown that successful implementation of EID services requires concerted efforts from various contextualized stakeholders whilst focusing on family-centered care. To maximize retention in EID and innovative ways of reaching mothers and babies through flexible guidelines are urgently needed.Nursing is a respect for dignity and treating every person equally. Qualifying competent and ethical nurses requires the incorporation of a professional code of ethics with clinical nursing practice. However, no study was conducted on the relationship between professional ethics and clinical nursing practice. Therefore this study aimed to determine correlation between professional ethics and pediatrics clinical practice from an achievement perspective. Accordingly, cross-sectional study design was conducted at Mizan-Tepi University using nursing students' academic achievements at professional ethics and pediatric practice. Collected data were entered into Epi info 7. SPSS version 21.0 was used to calculate spearman's rho correlation (r s) and coefficient of determination (R 2) at P  less then  .05. A total of 316 study participants comprising of 209 (66.14%) male and 107 (33.86%) female nursing students included in the current study. Nursing students' academic achievements at professional ethics was significantly and positively associated with achievements at pediatrics clinical practice (rs  = 0.4-0.6), P  less then  .001. Linear regression results revealed 25% to 26.7% coefficient determination for regular students and 18% to 22.9% for summer nursing students. To sum up, there was a significant positive association between achievements of students at professional ethics and pediatrics clinical practice. Therefore increasing students' academic achievement in professional ethics can further improve their achievements at pediatrics clinical practice. However, academic achievement in professional ethics explained 22.35% of the variability in achievements at pediatric clinical practice. 77.65% of the variability in pediatrics clinical practice was due to other factors that deserve another study.With the advent of Anti-Retroviral Therapy, Human Immune Virus, and Acquire Immuno-Deficiency Syndrome is increasingly becoming a chronic disease as life expectancy among People Living With HIV/AIDS has increased. For Children Living With HIV/AIDS the role of the caregivers becomes essential as caregivers' decisions affect CLWH health. However, the experiences of these caregivers are often unnoticed while all interventions are directed at PLWH. This study aimed at exploring the experiences of caregivers of CLWH in some selected hospitals in northern Ghana. This study employed a qualitative descriptive phenomenological approach. Purposive sampling technique was used to recruit 9 participants from 3 public hospitals in the Tamale Metropolis of Ghana. Data was manually analyzed using the approach of Collaizi and the findings were presented in themes and sub-themes. We conducted individual face to face interviews in English and Dagbani from September to November 2019. These interviews were conducted at the convenience of the participants in hospitals and at their homes.
