Abstract
Livelihoods have changed dramatically over the past decade in low- and middle-income countries (LMIC). These shifts are happening in tandem with shifts in individual and household food choice behaviors. This scoping review aimed to identify and characterize mechanisms through which livelihood changes could affect food choice behaviors in LMIC, including behaviors relating to food production, acquisition, preparation, distribution, and consumption. A literature search was conducted using 4 databases: PubMed, PsycInfo, AGRICOLA, and Embase. The search was further enhanced by expert solicitations. Studies were included if they measured or focused on a livelihood change, described or assessed a change in ≥1 food choice behavior, and focused on LMIC. Studies were excluded if they focused on migration from LMIC to a high-income country. Of the 433 articles that were identified, 53 met the inclusion criteria. Five mechanisms of how livelihood change can affect food choice were identified: occupation, locality, time, income, and social relations. Changes in occupation altered the balance of the availability and affordability of foods in local food environments compared with individual food production. Changes in location, time use, and income influenced where food was purchased, what types of foods were acquired, and how or where foods were prepared. Additionally, changes in social relationships and norms led to expanded food preferences, particularly among urban populations. Time limitations and higher discretionary income were associated with consumption of ultraprocessed foods. Understanding the relationships between the changes in livelihood occuring in LMIC and food choices of households in these countries can inform the development of policies, programs, and other actions to promote sustainable healthy diets and planetary health.

Abstract
Increased access to a variety of foods in low-and-middle-income countries (LMICs) has led to greater autonomy in food choice decision-making. Autonomy allows individuals to make decisions through negotiation of considerations in ways that are consistent with basic values. The aim of this study was to identify and describe how basic human values drive food choice in two diverse populations with transitioning food environments living in the neighboring East African countries of Kenya and Tanzania. Secondary data analysis was carried out on focus group discussions conducted with men and women in Kenya (n = 28) and Tanzania (n = 28) as part of prior studies on food choice. A priori coding based on Schwartz's theory of basic human values was conducted, followed by a narrative comparative analysis, which included review by original principal investigators. Values of conservation (security, conformity, tradition), openness to change (self-directed thought and action, stimulation, indulgence), self-enhancement (achievement, power, face), and self-transcendence (benevolence-dependability and -caring) were prominent drivers of food choice in both settings. Participants described how values were negotiated and highlighted existing tensions. For example, the value of tradition was cited as important in both settings but changing food contexts (e.g., new foods, diverse neighborhoods) increased prioritization of values like stimulation, indulgence, and self-directed thought and action. The application of a basic values framework was useful for understanding food choice in both settings. A focused understanding of how values drive food choice decision-making in the context of changing food availability in LMICs is essential for the promotion of sustainable healthy diets.

Abstract
Dramatic changes in daily life are leading to increased rates of obesity and non-communicable diseases (NCD) in Kenya, including among children. Parenting plays a vital role in helping children establish healthy eating habits to prevent obesity and NCDs. The objective of this study was to describe parenting identity and how attributes of parenting influence food parenting practices in an urban Kenyan context. A qualitative study design was employed with 18 participants recruited using quota sampling to include parents who were born in (n = 8) or migrated to Nairobi in the last five years (n = 10). In-depth qualitative interviews were conducted by an experienced ethnographic interviewer that inquired about parenting identity and food parenting practices. Transcripts were analyzed using thematic coding in a multi-step and emergent process. Parents described their parenting identities as an integration of tradition and personal experiences during their upbringing with the modern realities of daily life. Their own experiences with discipline, modern urban lifestyles, and social pressures were dominant influences on their identities. Parenting identities included four distinct but related attributes: good disciplinarian, trustworthy, protective, and balanced provider and nurturer. Food parenting practices were described as expressions of parenting identity and included the goals: children becoming better eaters; nourishing through food; impart joy; and bonding. The study findings illustrate the influence of modern urban lifestyles on food parenting identities and practices. Understanding emerging identities and practices in rapidly changing low- and middle-income countries (LMIC) contexts is essential for health promoting policies and programs.

Abstract
Preschool-aged children in the U.S. have suboptimal diets. Interventions to improve child nutrition focus on parents and their role in shaping social and physical home environments, which influence children's eating behaviors. Dietary assessment tools selected to measure intervention objectives, and how results are interpreted in key findings, are essential when examining children's diets. The objectives of this review were to (1) describe dietary assessment tools used in intervention studies in young children focused within the home environment; and (2) examine how the application of these dietary assessment tools addressed intervention objectives. PubMed and Web of Science were searched for English-language nutrition intervention studies that included children aged 2-5 years, had a home environment component, used a dietary assessment tool, and reported on diet-related outcomes. Seventeen studies were included. Intervention objectives focused on overall diet, specific food groups, eating occasions, and obesity prevention/treatment. Concordance of key findings with intervention objectives, type of tool used, and multiple tools within the same study varied with 8 studies aligning in objective and tool, 1 discordant in both, and 8 partially concordant or too broad to determine. This review highlights current challenges in measuring dietary intake in preschoolers and provides recommendations for alternative applications and strategies.

Abstract
Alternative caregivers (i.e., someone besides the primary caregiver who also takes care of children) make food choices for children. This study investigated what alternative caregivers consider when making food choices for children and their perspectives on their role in making food choices to feed children. In-depth interviews were conducted with 16 alternative caregivers of children aged 1-5 years old in semi-urban and urban areas of the State of Mexico in Mexico. Interviews were recorded, transcribed, coded, and analyzed using constant comparative method. Alternative caregivers described spaces and situations that exposed children to food while under their care. Alternative caregivers who spent longer periods of time with the child described more involvement in what the child ate. Healthy or nutritious food, cost of food and affection for children were important considerations for alternative caregivers when deciding what to feed the child. Alternative caregivers had a substantial role in child feeding, decisions about cooking, and advising mothers on how to feed their children. Efforts to promote healthy food choices for children should include targeting of alternative caregivers.

Abstract
Food choice for children has important implications in establishing early‐life dietary habits and preferences. Food choice for children has been studied as parent–child dyad dynamics, but little is known about the extended system of relationships in maternal food choice for children. The objective of this study was to understand the functions of mothers' social networks in the food choices that mothers make for their children ages 1 to 5 years old in rural Mexico. In‐depth interviews were conducted with 46 participants in three rural communities. The interviews inquired about participants' child‐feeding practices, personal and local beliefs about child feeding and the individuals with whom they had conversations about food and child feeding. All interviews were conducted in Spanish, audio‐recorded, transcribed verbatim, verified for quality and analysed using the constant comparative method. Five interconnected networks emerged, consisting of household family, non‐household family, community, children's initial school and health and nutritional programme personnel. Each network had functions in food choice that ranged from shared food decision‐making in the household family network to imparting formal dietary guidance in the health and nutritional programme personnel network. Across the networks, professionals, participants' mothers and mothers‐in‐law, community senior women and other women with children emerged as prominent figures whom participants would turn to for child‐feeding advice. These findings provide empirical evidence that social networks, as an organized system of interconnected relationships, have vital functions in establishing social norms for food choices made for children that can be leveraged to promote healthy food choices.

Abstract
Prostate cancer is the most commonly diagnosed non-skin cancer among all men and the second most common cause of death. To ameliorate the burden of prostate cancer, there is a critical need to identify strategies for providing men with information about prostate cancer screening and the importance of informed decision making. With mobile phones becoming more ubiquitous, many individuals are adopting their phones as sources for health information. The objective of this systematic review is to identify and evaluate commercially available apps for promoting informed prostate cancer screening decisions. Two keywords "prostate cancer screening" and "prostate cancer" were entered into the search engines of Google and iOS app stores in May 2017. Evaluations were conducted on apps' (a) quality, (b) grade-level readability, (c) cultural sensitivity, and (d) usability heuristics. None of the 14 apps meeting the inclusion criteria contained the full breadth of information covered in the 2016 American Cancer Society's Prostate Cancer Prevention and Early Detection Guidelines, but over half were inclusive of topics consistent with these guidelines. Most apps' readability was higher than an eighth-grade reading level. Most apps were also not framed and had a neutral tone. Only four apps met most criteria for being culturally sensitive to African Americans. Usability among apps was variable, but some contained major usability concerns. Recommendations for improving educational apps for prostate cancer screening include: disseminating evidence-based information; using culturally sensitive language; knowing the implications of the one and framing of content; making apps interactive; and following common usability principles.

Abstract
BACKGROUND Up to 70% of lung cancer survivors are affected by chronic obstructive pulmonary disease (COPD), a common, debilitating, comorbid disease. Lung cancer and COPD are both characterized by symptoms such as breathlessness, fatigue, and psychological distress. These distressing chronic symptoms are exacerbated by stress and detract from an individual's quality of life. OBJECTIVE The aim of this study was to identify and evaluate evidence-based, commercially available apps for promoting mindfulness-based strategies among adults with a COPD or lung cancer history (ie, chronic lung disease). METHODS For this review, an interdisciplinary research team used 19 keyword combinations in the search engines of Google and iOS app stores in May 2017. Evaluations were conducted on the apps' (1) content, (2) usability heuristics, (3) grade-level readability, and (4) cultural sensitivity. RESULTS The search resulted in 768 apps (508 in iOS and 260 in Google stores). A total of 9 apps met the inclusion criteria and received further evaluation. Only 1 app had below an eighth-grade reading level; the ninth one did not have enough text to calculate a readability score. None of the 9 apps met the cultural sensitivity evaluation criteria. CONCLUSIONS This systematic review identified critical design flaws that may affect the ease of using the apps in this study. Few mobile apps promote mindfulness-based strategies among adults with chronic lung disease (ie, COPD or lung cancer or both), but those that exist, overall, do not meet the latest scientific evidence. Recommendations include more stringent regulation of health-related apps, use of evidence-based frameworks and participatory design processes, following evidence-based usability practices, use of culturally sensitive language and images, and ensuring that content is written in plain language.

Abstract
Additional research is needed to guide the design of narratives for use in practice-oriented, naturalistic settings to maximize health behavior change, particularly among populations affected by health disparities. This mixed-methods study explored the influence of cultural tailoring and emotional arousal on identification and message recall in narratives promoting childhood obesity prevention among 40 Mexican American mothers. Participants were also asked about narrative exposure, narrative preferences, and beliefs about the purpose of a story. Participants were randomly assigned to listen to two stories: (a) a story tailored on noncultural or cultural variables, and (b) a story designed to enhance or minimize emotional arousal. Participants reported high engagement and identification with all stories. Participants generally envisioned protagonists as Latina, despite limited cues, and identified with protagonists in four ways: sharing personal characteristics; having similar thoughts and feelings; engaging in similar actions; and experiencing similar situations. Mothers were most interested in narratives that helped them to improve their lives. Findings from this study yield several hypotheses for consideration in future study, including ways in which story setting and message enactment may moderate message recall.

Abstract
BACKGROUND This qualitative study explored values, attitudes, and beliefs held by Mexican-origin mothers of preschool-aged children to enhance understanding of cultural influences on behaviors associated with childhood obesity risk. METHODS During face-to-face interviews, 39 Mexican-origin mothers of preschool-aged children discussed their hopes for their children, their image of the perfect mother, Mexican and American foods, why they taught their children about these foods, and their opinions about television (TV) viewing language. RESULTS Participants wanted their children to become successful, "good" people, which necessitated doing well in school. Mothers also wanted their children to know them, which required understanding the mothers' Mexican backgrounds. Mothers wanted their children to maintain Mexican values and identities. Some mothers viewed American culture as harmful. Many participants prepared their child for going to Mexico by exposing them to Mexican culture and foods. Some mothers fed their children American foods to prepare them for school. Perceptions of American foods generally reflected stereotypical unhealthy foods. TV helped teach children Spanish and English. Being a good mother was core to participants' identities; thus, hearing about child overweight made some mothers feel like failures. CONCLUSIONS Health promotion programs may be more salient to mothers if they: underscore how a healthy weight can help children in school; teach mothers to prepare healthy American foods that their children will encounter in kindergarten; assist mothers in teaching their children about Mexico; and present information about childhood obesity in ways that reinforce what mothers are doing well, enhance mothers' self-efficacy, and allay feelings of failure.

Abstract
We present a numerical study of the effect of interstitial air on a vertically vibrated granular bed within one period of oscillation. We use a three-dimensional molecular-dynamics simulation including air phenomenologically. The simulations are validated with experiments made with spherical glass beads in a rectangular container. After validation, results are reported for a granular column of 9000 grains and approximately 50 layers deep (at rest), agitated with a sinusoidal excitation with maximal acceleration 4.7g at 11.7 Hz. We report the evolution of density, granular temperature, and coordination number within a vibration cycle, and the effect of interstitial air on those parameters. In three-dimensional computer simulations we found that the presence of interstitial air can promote the collective motion of the granular material as a whole.

Abstract
We find by Monte Carlo simulations that the distribution of Voronoï cell sizes for the parking lot model follows a gamma distribution with shape parameter k approximately 2 for high enough packing fractions varphi . A gamma distribution of Voronoï cells sizes was found recently by Aste [Europhys. Lett. 79, 24003 (2007)] in experiments of static packings of monodisperse spheres. This statistic implies that, for high varphi , Edwards' compactivity of the parking lot model depends linearly on the average volume per cell, as predicted by the statistical mechanics calculation of Tarjus and Viot, which explicitly counted the blocked configurations of this model [Phys. Rev. E 69, 011307 (2004)].

Abstract
INTRODUCTION Living donor renal transplantation is a treatment option for patients on dialysis in view of the ever-growing transplantation waiting lists and the stagnation in the number of deceased donors. OBJECTIVES The objectives of this study were to provide retrospective review of our living donor kidney transplantation series (1978-2003) and analysis of graft survival prognostic factors. MATERIALS AND METHODS Among 121 living donor transplantations, the donor mean age was 50.9 years (SD, 1.53) and recipient mean age was 30.4 years (SD, 1.4). Eighty-eight percent of donors were women, 90% were related: siblings 21%, parents 69%, and spouses 6.6%. Kidney failure was of nephrological etiology in 65% of patients and urologic in 15.6%. Eighty-four percent were primary grafts and 16% were second ones. Also, 66.7% of kidneys were placed in the iliac fossa and the rest were left orthotopic approaches. Other analyzed variables included donor gender, acute rejection episodes (ARE), creatinine levels at 1 and 6 months, hypertension (HT), and pediatric recipients. RESULTS Univariate analysis (Kaplan-Meier) showed that, in patients suffering from ARE or not, the mean graft survival was 7.5 and 15 years, respectively (P <.05). Mean graft survival among patients with nephrological problems was 8 years and in those with urologic etiology 15 years (P < .05). Multivariate analysis with Cox regression showed that etiology, ARE, and creatinine level at 6 months after transplantation were independent prognostic variables for graft failure. The overall graft survival rates were 78% at 5 years, 58% at 10 years, 42% at 15 years, and 24% at 20 years follow-up. CONCLUSION Living donor kidney transplantation is a valid treatment choice for end-stage patients with excellent graft survival rates, especially in cases of urologic etiology. Development of new immunosupressant strategies will help improve outcomes.

Abstract
We present a simple non-radioactive cytometry-based assay that permits the simultaneous quantitation of cell adhesion of distinct subsets of cells contained in a mixture without any previous fractionation. The procedure is simple and highly reproducible and has the advantage of confining the quantitation of cell adhesion to live cells only. This new approach is based on counting the absolute number of cells. This is done by adding known numbers of distinguishable beads to the cell suspension and counting beads and cells in a cytometer. Quantitation of adhesion is accomplished by counting each subpopulation of cells before and after the adhesive process. To illustrate this methodology we determined adhesion of Ramos cells to monolayers of endothelial cells and its inhibition by specific antibodies. Also, we determined adhesion to endothelial cells of B lymphocytes and subsets of T lymphocytes present in a preparation of unfractionated human mononuclear cells. The results presented here demonstrate that the new assay has the required properties to be used in the quantitation of cell adhesion.

Abstract
Pseudomyxoma peritonei is a rare entity manifested by implants of a mucinous gelatinous material arising from either the appendix or ovary and involves the peritoneal cavity, peritoneum and omentum. Preoperative diagnosis is feasible by means of radiographic studies. The main step in the treatment is debulking surgery with appendectomy, bilateral oophorectomy and omentectomy. Adjuvant radiotherapy and chemotherapy has been used. Long term survival is around 54% at five years. Here we present a case of a ruptured mucocele of the appendix and pseudomyxoma who presents as massive increase in the abdominal girth of two years evolution.
