Infant Feeding Outcomes From a Culturally-Adapted Early Obesity Prevention Program for Immigrant Chinese American Parents.

OBJECTIVE: To examine whether a cultural adaptation of an early childhood obesity prevention program promotes healthy infant feeding practices. METHODS: Prospective quasi-experimental study of a community-engaged multiphasic cultural adaptation of an obesity prevention program set at a federally qualified health center serving immigrant Chinese American parent-child dyads (N = 298). In a group of historical controls, we assessed early infant feeding practices (breastfeeding, sugar-sweetened beverage intake) in 6-month-olds and then the same practices alongside early solid food feeding practices (bottle weaning, fruit, vegetable, sugary or salty snack consumption) in 12-month-olds. After implementation, we assessed these practices in an intervention cohort group at 6 and 12 months. We used cross-sectional groupwise comparisons and adjusted regression analyses to evaluate group differences. RESULTS: At 6 months, the intervention group had increased odds of no sugar-sweetened beverage intake (aOR: 5.69 [95% confidence interval (CI): 1.65, 19.63], P = .006). At 12 months, the intervention group also had increased odds of no sugar-sweetened beverage intake (aOR: 15.22 [95% CI: 6.33, 36.62], P < .001), increased odds of bottle weaning (aOR: 2.34 [95% CI: 1.05, 5.23], P = .03), and decreased odds of sugary snack consumption (aOR: 0.36 [0.18, 0.70], P = .003). We did not detect improvements in breastfeeding, fruit, vegetable, or salty snack consumption. CONCLUSIONS: A cultural adaptation of a primary care-based educational obesity prevention program for immigrant Chinese American families with low income is associated with certain healthy infant feeding practices. Future studies should evaluate cultural adaptations of more intensive interventions that better address complex feeding practices, such as breastfeeding, and evaluate long-term weight outcomes.

Multidimensional neural representations of social features during movie viewing.

The social world is dynamic and contextually embedded. Yet, most studies utilize simple stimuli that do not capture the complexity of everyday social episodes. To address this, we implemented a movie viewing paradigm and investigated how everyday social episodes are processed in the brain. Participants watched one of two movies during an MRI scan. Neural patterns from brain regions involved in social perception, mentalization, action observation and sensory processing were extracted. Representational similarity analysis results revealed that several labeled social features (including social interaction, mentalization, the actions of others, characters talking about themselves, talking about others and talking about objects) were represented in the superior temporal gyrus (STG) and middle temporal gyrus (MTG). The mentalization feature was also represented throughout the theory of mind network, and characters talking about others engaged the temporoparietal junction (TPJ), suggesting that listeners may spontaneously infer the mental state of those being talked about. In contrast, we did not observe the action representations in the frontoparietal regions of the action observation network. The current findings indicate that STG and MTG serve as key regions for social processing, and that listening to characters talk about others elicits spontaneous mental state inference in TPJ during natural movie viewing.

The nature of science: The fundamental role of natural history in ecology, evolution, conservation, and education.

There is a contemporary trend in many major research institutions to de-emphasize the importance of natural history education in favor of theoretical, laboratory, or simulation-based research programs. This may take the form of removing biodiversity and field courses from the curriculum and the sometimes subtle maligning of natural history research as a "lesser" branch of science. Additional threats include massive funding cuts to natural history museums and the maintenance of their collections, the extirpation of taxonomists across disciplines, and a critical under-appreciation of the role that natural history data (and other forms of observational data, including Indigenous knowledge) play in the scientific process. In this paper, we demonstrate that natural history knowledge is integral to any competitive science program through a comprehensive review of the ways in which they continue to shape modern theory and the public perception of science. We do so by reviewing how natural history research has guided the disciplines of ecology, evolution, and conservation and how natural history data are crucial for effective education programs and public policy. We underscore these insights with contemporary case studies, including: how understanding the dynamics of evolutionary radiation relies on natural history data; methods for extracting novel data from museum specimens; insights provided by multi-decade natural history programs; and how natural history is the most logical venue for creating an informed and scientifically literate society. We conclude with recommendations aimed at students, university faculty, and administrators for integrating and supporting natural history in their mandates. Fundamentally, we are all interested in understanding the natural world, but we can often fall into the habit of abstracting our research away from its natural contexts and complexities. Doing so risks losing sight of entire vistas of new questions and insights in favor of an over-emphasis on simulated or overly controlled studies.

SMARTer Goalsetting: A Pilot Innovation for Coaches During the Transition to Residency.

PROBLEM: Ability to set goals and work with coaches can support individualized, self-directed learning. Understanding the focus and quality of graduating medical student and first-year resident goals and the influence of coaching on goal-setting can inform efforts to support learners through the transition from medical school to residency. APPROACH: This observational study examined goal-setting among graduating medical students and first-year residents from April 2021 to March 2022. The medical students set goals while participating in a Transition to Residency elective. The residents in internal medicine, obstetrics and gynecology, emergency medicine, orthopedics, and pathology set goals through meeting 1:1 with coaches. Raters assessed goals using a 3-point rubric on domains of specific, measurable, attainable, relevant, and timely (i.e., SMART goal framework) and analyzed descriptive statistics, Mann-Whitney U tests, and linear regressions. OUTCOMES: Among 48 medical students, 30 (62.5%) set 108 goals for early residency. Among 134 residents, 62 (46.3%) entered goals. Residents met with coaches 2.8 times on average (range 0-8 meetings, median = 3). Goal quality was higher in residents than medical students (average score for S: 2.71 vs 2.06, P < .001; M: 2.38 vs 1.66, P < .001; A: 2.92 vs 2.64, P < .001; R: 2.94 vs 2.86, P = .002; T: 1.71 vs 1.31, P < .001). The number of coaching meetings was associated with more specific, measurable goals (specific: F [1, 1.02] = 6.56, P = .01, R2 = .10; measurable: F [1, 1.49] = 4.74, P = .03, R2 = .07). NEXT STEPS: Learners set realistic, attainable goals through the transition to residency, but the goals could be more specific, measurable, and timely. The residents set SMARTer goals, with coaching improving goal quality. Understanding how best to scaffold coaching and support goal-setting through this transition may improve trainees' self-directed learning and well-being.

The Transition From Medical Student to Resident: A Qualitative Study of New Residents' Perspectives.

PURPOSE: To understand the learner's perspective on the transition from medical school to residency and to develop a conceptual model for how learners experience the transition from student to resident. METHOD: This prospective qualitative study explored the experience of first-year residents using semistructured, one-on-one telephone interviews. Ten first-year residents who participated in the Transition to Residency elective as fourth-year students at the New York University Grossman School of Medicine in April 2018 participated from December 2018 to April 2019. Using a 3-phase coding process and grounded theory methodology, the authors identified categories, which they organized into broader themes across interview transcripts and used to develop a conceptual model. RESULTS: From the perspective of new residents, developing professional identity is the core construct of the transition experience. The residents focused on individual aspects of the experience-professional identity, self-awareness, professional growth, approach to learning, and personal balance-and external aspects-context of learning, professional relationships, and challenges in the context of their new role. Across these 8 categories, 5 broader themes emerged to describe an abrupt change in educational environment, an immersive experience of learning as a resident, ambivalence and tensions around the new role, navigation of professional relationships, and balance and integration of working in medicine with personal lives and goals. A conceptual model illustrates this phenomenon as a cell where professional identity and growth (the nucleus) is surrounded by interactions with patients and other members of the medical team (in the cytoplasm) that create a substrate for learning and development. CONCLUSIONS: This study suggests that being immersed in the residency experience is how medical students transition to resident physicians. Educational interventions that allow learners to acclimate to the experience of being a doctor through gradual exposure to authentic interactions have the potential to bridge the abrupt transition.

webpic: A flexible web application for collecting distance and count measurements from images.

Despite increasing ability to store and analyze large amounts of data for organismal and ecological studies, the process of collecting distance and count measurements from images has largely remained time consuming and error-prone, particularly for tasks for which automation is difficult or impossible. Improving the efficiency of these tasks, which allows for more high quality data to be collected in a shorter amount of time, is therefore a high priority. The open-source web application, webpic, implements common web languages and widely available libraries and productivity apps to streamline the process of collecting distance and count measurements from images. In this paper, I introduce the framework of webpic and demonstrate one readily available feature of this application, linear measurements, using fossil leaf specimens. This application fills the gap between workflows accomplishable by individuals through existing software and those accomplishable by large, unmoderated crowds. It demonstrates that flexible web languages can be used to streamline time-intensive research tasks without the use of specialized equipment or proprietary software and highlights the potential for web resources to facilitate data collection in research tasks and outreach activities with improved efficiency.

Perception of Child Weight and Feeding Styles in Parents of Chinese-American Preschoolers.

Parent perception of weight and feeding styles are associated with obesity in other racial groups but have not been explored in-depth in Chinese-American preschoolers. Cross-sectional survey of 253 Chinese-American parents with preschoolers was performed in a community clinic. Regression analysis was used to assess relationships between parental perception of weight and feeding styles. Parent under-perception of weight was common but more likely in boys than girls (χ2 = 4.91, p = 0.03). Pressuring was also greater in boys [adjusted mean difference (95% CI) 0.24 (0.004, 0.49)]. In girls, pressuring was lower for children perceived as overweight [adjusted mean difference in CFQ scores -0.75 (-1.27, -0.23)]; in boys, pressuring was high regardless of perceived child weight. Weight perceptions and feeding styles related to childhood obesity in other groups were identified in Chinese-American families. Parent under-perception of child weight and pressure to eat were more common in boys. These factors should be addressed in Chinese-American preschooler obesity prevention programs.

Use of simulation-based education: a national survey of pediatric clerkship directors.

OBJECTIVE: To document the prevalence of simulation-based education (SBE) for third- and fourth-year medical students; to determine the perceived importance of SBE; to characterize the barriers associated with establishing SBE. METHODS: A 27-item survey regarding simulation was distributed to members of the Council on Medical Student Education in Pediatrics (COMSEP) as part of a larger survey in 2012. RESULTS: Seventy-one (48%) of 147 clerkship directors (CD) at COMSEP institutions responded to the survey questions regarding the use of SBE. Eighty-nine percent (63 of 71) of CDs reported use of SBE in some form: 27% of those programs (17 of 63) reported only the use of the online-based Computer-Assisted Learning in Pediatrics Program, and 73% (46 of 63) reported usage of other SBE modalities. Fifty-four percent of CDs (38 of 71) agreed that SBE is necessary to meet the requirements of the Liaison Committee on Medical Education (LCME). Multiple barriers were reported in initiating and implementing an SBE program. CONCLUSIONS: SBE is commonly used for instruction during pediatric undergraduate medical education in North American medical schools. Barriers to the use of SBE remain despite the perception that it is needed to meet requirements of the LCME.

Gastric emptying rate and chyme characteristics for cooked brown and white rice meals in vivo.

BACKGROUND: Rice structure is important to rice grain and starch breakdown during digestion. The objective of this study was to determine the gastric emptying and rice composition during gastric digestion of cooked brown and white medium-grain (Calrose variety) rice using the growing pig as a model for the adult human. RESULTS: Brown and white rice did not show significantly different gastric emptying rates of dry matter or starch, but brown rice had slower protein emptying (P < 0.05). Moisture content was greater and pH was lower in the distal stomach compared to the proximal stomach (P < 0.0001), and varied with time (P < 0.0001). The mechanism of physical breakdown for brown and white rice varied. Brown rice exhibited an accumulation of bran layer fragments in the distal stomach, quantified by lower starch and higher protein content. CONCLUSION: The quantity of gastric secretions observed after a brown or white rice meal may be related to the meal buffering capacity, and are accumulated in the distal stomach. The delayed rate of protein emptying in brown rice compared to white rice was most likely due to the accumulation of bran layers in the stomach.

Nueva alternativa en el manejo del craneofaringioma sólido quístico: bleomicina intracavitaria más resección neuroendoscópica / New management of solid cystic craniopharyngioma: intracavitary bleomycin plus neuroendoscopic resection

Presentamos de manera preliminar el manejo y evolución de una niña de nueve años de edad en quién se estableció el diagnóstico de craneofaringioma sólido con componente quístico gigantes siendo tratada con administración de un total de 94,20 mg de bleomicina intracavitaria a través de un reservorio tipo Ommaya y resección del componente tumoral localizado en el tercer ventrículo además de fenestración del piso del mismo, ambas por vía neuroendoscópica. La evolución ha sido satisfactoria, siendo dada de alta con recuperación parcial de la función visual y sin hipertensión endocraneana, esperándose máxima resolución del craneofaringioma luego de algunos meses.
