Beyond Broca's area: why undergraduate neuroscience education matters

: Patients with psychiatric illness often present a unique challenge to medical students: in contrast to some medical conditions, in which patients may seem to be stricken by a disease, patients with certain psychiatric illnesses may seem complicit with the illness. Questions of free will, choice, and the role of the physician can quickly become overwhelming. This may result in students feeling helpless, disinterested, or even resentful. Here we argue that integrating a modern neuroscience perspective into medical education allows students to conceptualize psychiatric patients in a way that promotes empathy and enhances patient care. Specifically, a strong grasp of neuroscience prevents the future physician from falling into dualistic thinking in which the psychosocial aspects of a patient's presentation are considered beyond the realm of medicine. The value of incorporating neuroscience into a full, biopsychosocial formulation is demonstrated with the case example of a "difficult patient."

Comparison of a Novel Trainer to a Traditional Swine Model for Training Providers in Lateral Canthotomy and Cantholysis.

RESEARCH OBJECTIVE: Military personnel are at greater risks of head and facial traumas and permanent blindness from orbital compartment syndrome in modern warfare. Rapid treatment must be implemented with a low-risk surgical remedy: lateral canthotomy and cantholysis (LCC). Traditional training of LCC is primarily performed using an animal tissue trainer (ATT); however, limitations to these types of trainers exist. Therefore, our research objectives were focused on highlighting the effectiveness, benefits, and vision-saving potential of learning LCC on a synthetic trainer. METHODS: Participants included 22 second-year medical students and 6 healthcare professionals. A pre-quiz assessed baseline knowledge. Next, an experienced ophthalmologist provided an overview and instruction. Subjects were randomized to either the synthetic trainer or the ATT and then switched to the other model for comparison. After performing LCC procedures on both models, a post-quiz and survey were administered. RESULTS: Participants found the synthetic trainer easier to use than the ATT model (p < 0.01). There was no statistically significant preference (p = 0.23), or preference of practical eye anatomy (p = 0.26) between the trainers. Post-quiz results demonstrated an overall improvement from pre-quiz scores for participants (p < 0.001). CONCLUSIONS: The synthetic trainer is comparable to the traditional swine model for training LCC procedures, and should be considered as a future training platform.

Methicillin-Resistant Staphylococcus aureus: The Effects Are More Than Skin Deep.

OBJECTIVES: To assess the psychosocial effects of a methicillin-resistant Staphylococcus aureus (MRSA) diagnosis on the households of children with MRSA skin and soft tissue infection (SSTI). STUDY DESIGN: We constructed and administered an interview to the primary caregiver within the home of a child with a history of MRSA SSTI. RESULTS: Seventy-six households were enrolled. Survey responses were analyzed and grouped into 4 themes: health behavior changes, disclosure, social interactions, and knowledge/awareness. The most common theme was disclosure; 91% of participants reported sharing their child's MRSA diagnosis with someone outside of the household. Forty-two percent of respondents reported a change in the manner in which household contacts interacted as a result of the index patient's MRSA diagnosis, including isolating the index patient from other children in the household. Many households reported adopting enhanced personal hygiene behaviors and environmental cleaning routines. Thirty-eight percent of participating households reported altering how they interact with people outside of their home, largely to avoid spreading MRSA to vulnerable individuals. In addition, many participants perceived that others regarded them with caution, especially at daycare, whereas other affected households were excluded from family gatherings. CONCLUSION: Primary caregivers of children with MRSA SSTI reported changing their health behaviors, altering their interactions with people outside of their home, and feeling isolated by others in response to their child's MRSA diagnosis. The findings of our study highlight a need for community interventions and education to prevent the negative psychosocial repercussions associated with MRSA.

Metal contents of marine turtle eggs (Chelonia mydas; Lepidochelys olivacea) from the tropical eastern pacific and the implications for human health.

Concentrations of eight elements were measured in Chelonia mydas and Lepidochelys olivacea eggs collected along the Pacific coast of Panama. Manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), and mercury (Hg) concentrations were similar to previous reports of these species from around the world, while lead (Pb) was lower than previous reports. Cd posed the highest health risk to people who regularly eat the eggs, with average consumption rates leading to target hazard quotients (THQ) of up to 0.35 ± 0.15. Our conclusions indicate that current turtle egg consumption in isolated, coastal Pacific communities may pose a health concern for young children, and that youth and young adults should limit their consumption of turtle eggs to reduce their total intake of nonessential metals.

Gastrostomy Tube Feeding after Neonatal Complex Cardiac Surgery Identifies the Need for Early Developmental Intervention.

OBJECTIVE: To compare the proportion of developmental delay in early complex cardiac surgery (CCS) survivors with and without gastrostomy tube feeding (GTF). To explore acute care predictors of GTF that might help improve care in CCS survivors. STUDY GROUP: This comparison study of 2 groups within an inception cohort included 334 CCS survivors after cardiopulmonary bypass at ≤6 weeks of age (2005-2012) who did not require extracorporeal membrane oxygenation or heart transplantation. Children were assessed at 21 ± 3 months with the Bayley Scales of Infant and Toddler Development-Third Edition and the Adaptive Behavior Assessment System-Second Edition: general adaptive composite score. Delay was determined by scores >2 SD below mean. The χ(2) test compared groups. Predictors of GTF were analyzed using multiple logistic regression analysis, results expressed as OR with 95% CI. RESULTS: Of the survivors, 67/334 (20%) had GTF any time before the 21-month assessment. Developmental delays in children with GTF were cognitive in 16 (24%), motor in 18 (27%), language in 24 (36%) vs without GTF in 7 (3%), 8 (3%), and 32 (12%), respectively (P < .001). Gastrostomy group had almost 8 times the number of children delayed on the general adaptive composite score. Independent OR for GTF are presence of a chromosomal abnormality, OR 4.6 (95% CI 1.8, 12.0) (P = .002), single ventricle anatomy, OR 3.4 (95% CI 1.7, 6.8) (P < .001), total postoperative days of open sternum, OR 1.15 (95% CI 1.1, 1.3) (P = .031), and total number of hospital days at CCS, OR 1.03 (95% CI 1.1, 1.04) (P = .002). CONCLUSIONS: GTF identifies CCS survivors at risk for delay, who would benefit from early developmental intervention. The described mostly nonmodifiable predictors may guide counseling of these children's families.

Risk factors for and outcomes of acute kidney injury in neonates undergoing complex cardiac surgery.

OBJECTIVE: To characterize the epidemiology of and identify risk factors for neonatal cardiac surgery-associated acute kidney injury (CS-AKI) and determine its impact on clinical outcomes. STUDY DESIGN: Using secondary analysis of data from an ongoing multiprovincial prospective cohort study, we studied 264 neonates undergoing complex cardiac repair. CS-AKI was defined based on the Acute Kidney Injury Network (AKIN) definition. We used regression modeling and survival analysis (adjusting for covariates) to evaluate associations. RESULTS: CS-AKI occurred in 64% of the neonates in our study cohort. Lower age, longer cardiopulmonary bypass time, hypothermic circulatory arrest, type of repair, lower preoperative serum creatinine (SCr) level, lower gestational age, and preoperative ventilation were independent risk factors for developing CS-AKI. Neonates with CS-AKI had longer times to extubation, intensive care discharge, and hospital discharge, after adjusting for covariates. Mortality was significantly increased in neonates with AKIN stage 2 or higher CS-AKI. The neonates with CS-AKI had a lower z-score for height at 2-year follow-up and were seen by more specialists. CONCLUSION: Neonatal CS-AKI is common and independently predicts important clinical outcomes, including mortality. Many risk factors are similar to those in older children, but some are unique to neonates. The observation that lower baseline SCr predicts CS-AKI merits further study. The AKIN definition, based on preoperative SCr value, is a reasonable method for defining CS-AKI in neonates. Many previous studies of CS-AKI have excluded neonates; we suggest that future intervention studies on approaches to reducing CS-AKI incidence and improving outcomes should include neonates.

The effectiveness of youth centers in increasing use of sexual and reproductive health services: a systematic review.

This study presents findings from a systematic review of the evidence regarding the effectiveness of youth centers in increasing use of sexual and reproductive health (SRH) services in lower- and middle-income countries. Evidence from peer-reviewed and gray literature between 1990 and 2010 was reviewed. After the screening of 3,769 citations, 21 studies reporting on 17 youth center programs were included, and were ranked by strength of evidence. Considerable consistency in findings across studies was observed. Youth centers generally served a relatively small proportion of young people living nearby. The main users were young men attending school or college, with a significant proportion older than the target age. Users of the on-site SRH services were predominantly young women, with a significant proportion older than the target age group. Uptake of services was generally low. Despite widespread emphasis on youth centers as a strategy for encouraging young people to access SRH services, results from these studies have not been encouraging, and cost-effectiveness for these purposes is likely to be low.
