Identifying Youth Problem Profiles and Predicting Remission Following Mental Health Treatment.

This study utilized latent profile analysis to categorize youth served by a public mental health setting into homogenous classes. Then, associations between class membership and meeting clinical criteria by the latest assessment were examined. Caregiver responses to the Ohio Scales, Short Form, Problem Severity Scale for 1090 youth completed at entry into this public mental health system were subjected to latent profile analysis. This method classifies youth into categories based on mental health problem profiles, in order to determine the degree to which these groupings are related to later mental health outcomes. The classification of youth cases that emerged was then used to predict clinical remission at or nearest end of treatment, including final Ohio Scales Problem Severity scores and a measure of day-to-day functioning, the Child and Adolescent Functional Assessment Scale (CAFAS). A four-class model was identified as best representing the data, reflecting a relatively low-risk class (63.3% of the sample), an internalizing class (23.2%), a delinquency class (8.8%), and a high-risk class (4.7%). Individuals in the internalizing and high-risk classes had lower likelihoods of achieving problem remission than those in the low-risk and delinquency classes at the time of their last completed Ohio Scales. Additionally, youth assigned to the delinquency and high-risk classes had lower likelihoods of reaching functional impairment remission than those in the internalizing and low-risk classes. Youth membership in a class based on initial problem scores can be utilized to predict clinical remission over the course of treatment in public mental health care. Such class-based predictions support other methods of predicting outcomes and can be used by clinicians to develop more informed treatment plans and to adjust treatment based on such classifications.

Therapist and Youth Predictors of Specific Practices Derived from the Evidence-Base in Community Mental Health.

Over the past several years, youth treatment research has moved toward understanding the dissemination and implementation of evidence-based practices (EBPs). As a result, studies have focused on identifying predictors that aid in successful adoption and sustainment of EBPs. Theories of behavior change posit that therapist knowledge and attitudes play a fundamental role in EBP adoption; however, studies have produced mixed findings, which may be an artifact of broad definitions of both EBP knowledge and EBP itself. The current study was an examination of 46 youth community therapists and the extent to which varying types of knowledge and attitudes as well as youth characteristics predicted specific practices derived from the evidence-base. Results suggested that specific EBP knowledge predicted specific practices, highlighting the need for more specificity when examining predictors of EBP use. Therapists' attitudes, demographic characteristics, and youth characteristics were also significant predictors of EBP use. Future research should consider examining discrete and specific practices to better understand and predict therapists' future behavior.

Reliable Change and Outcome Trajectories Across Levels of Care in a Mental Health System for Youth.

Knowledge of mental health treatment outcome trajectories across various service types can be valuable for both system- and client-level decision-making. Using longitudinal youth functional impairment scores across 2807 treatment episodes, this study examined outcome trajectories and estimated the number of months required for reliable change across nine major services (or levels of care). Results indicate logarithmic improvement trajectories for a majority of levels of care and significant differences in time until improvement ranging from 4 to 12 months. Findings can guide system-level policies on lengths of treatment and service authorizations and provide expected treatment response data for client-level treatment decisions.

Predictors of use of evidence-based practices for children and adolescents in usual care.

Practice data from 74 therapists providing public mental health services to 519 youth ages 5-19 were examined. Multilevel modeling suggested child and therapist characteristics predicted use of practices derived from the evidence-base (PDEB) and use of practices with minimal evidence support (PMES). Longer episode length predicted greater receipt of PDEB; older youth, males, and youth in out-of-home levels of care were more likely to receive PMES; and youth receiving an evidence-based treatment program were less likely to receive PMES. Professional specialty and theoretical orientation significantly predicted PDEB whereas therapist characteristics did not predict PMES. Implementation implications are discussed.

Use of whole grain and refined flour from tannin and non-tannin sorghum (Sorghum bicolor (L.) Moench) varieties in frybread.

Frybreads were prepared using wheat flour and wheat-sorghum composite flours (refined and whole grain; white, tannin-free and red, tannin-containing) at 0, 25, 50, and 75% sorghum flour. Hardness, volume, specific volume, color, and oil uptake were determined. Frybreads made with refined white, tannin-free sorghum were also evaluated in a sensory panel. Substitution of sorghum flour for wheat flour reduced the volume and increased the darkness of the fried dough pieces compared with wheat flour controls. Oil absorption was unaffected when using white, tannin-free sorghum. When using red, tannin-containing sorghum, oil absorption increased for refined flour and decreased for whole grain flour, suggesting that a component only present in the whole grain tannin-containing Sorghum--perhaps tannins themselves--may decrease oil uptake. Panelists rated frybreads containing up to 50% white, tannin-free sorghum flour as not significantly different from control frybreads made with refined wheat flour.

Making the professionalism curriculum for undergraduate medical education more relevant.

BACKGROUND: This study was an assessment of the professionalism curriculum at a community-based medical school from the perspective of undergraduate medical students. AIMS: The goal of this study was to ascertain the perspectives of faculty and students on their interpretations of professionalism and its role in medical education to improve and expand existing professionalism curricula. METHOD: An online survey was created and sent to all students (n = 245) and selected faculty (n = 41). The survey utilized multiple choice and open-ended questions to allow responders to provide their insights on the definition of professionalism and detail how professionalism is taught and evaluated at their institution. A content analysis was conducted to categorize open-ended responses and the resulting themes were further examined using SPSS 20.0 for Windows (IBM Corp., Armonk, NY) frequency analyses. RESULTS: Students and faculty respondents were similar in their definitions of medical professionalism and their perceptions of teaching methods. Role modeling was the most common and preferred method of professionalism education. Responses to whether evaluations of professional behavior were effective suggested both students and faculty are unclear about current professionalism assessments. CONCLUSION: This study showed that a cohesive standardized definition of professionalism is needed, as well as clearer guidelines on how professionalism is assessed.

Screening and determination of polycyclic aromatic hydrocarbons in seafoods using QuEChERS-based extraction and high-performance liquid chromatography with fluorescence detection.

A rapid, sensitive, and accurate method for the screening and determination of polycyclic aromatic hydrocarbons (PAHs) in edible seafood is described. The method uses quick, easy, cheap, effective, rugged, and safe (QuEChERS)-based extraction and HPLC with fluorescence detection (FLD). The method was developed and validated in response to the massive Deepwater Horizon oil spill in the Gulf of Mexico. Rapid and highly sensitive PAH screening methods are critical tools needed for oil spill response; they help to assess when seafood is safe for harvesting and consumption. Sample preparation involves SPE of edible seafood portions with acetonitrile, followed by the addition of salts to induce water partitioning. After centrifugation, a portion of the acetonitrile layer is filtered prior to analysis via HPLC-FLD. The chromatographic method uses a polymeric C18 stationary phase designed for PAH analysis with gradient elution, and it resolves 15 U.S. Environmental Protection Agency priority parent PAHs in fewer than 20 min. The procedure was validated in three laboratories for the parent PAHs using spike recovery experiments at PAH fortification levels ranging from 25 to 10 000 microg/kg in oysters, shrimp, crab, and finfish, with recoveries ranging from 78 to 99%. Additional validation was conducted for a series of alkylated homologs of naphthalene, dibenzothiophene, and phenanthrene, with recoveries ranging from 87 to 128%. Method accuracy was further assessed based on analysis of National Institute of Standards and Technology Standard Reference Material 1974b. The method provides method detection limits in the sub to low ppb (microg/kg) range, and practical LOQs in the low ppb (microg/kg) range for most of the PAH compounds studied.

Scoping Review of Economical, Efficient, and Effective Cultural Competency Measures.

Identifying practical and effective tools to evaluate the efficacy of cultural competency (cc) training in medicine continues to be a challenge. Multiple measures of various lengths and stages of psychometric testing exist, but none have emerged as a "gold standard." This review attempts to identify cc measures with potential to economically, efficiently, and effectively provide insight regarding the value of cc training efforts to make it easier for wider audience utilization. A scoping review of 11 online reference databases/search engines initially yielded 9,626 items mentioning cc measures. After the initial review, focus was placed on measures that assessed cultural competence of medical students, residents, and/or attending physicians. Six measures were identified and reviewed: (1) Cross-Cultural Care Survey, (2) Cultural Competence Health Practitioner Assessment, (3) Cultural Humility Scale, (4) Health Beliefs Attitudes Survey, (5) Tool for Assessing Cultural Competency Training, and (6) the Tucker-Culturally Sensitive Health-Care Provider Inventory. Relevant literature documenting use and current psychometric assessments for each measure were noted. Each measure was found to be of value for its particular purpose but needs more strenuous reliability and validity testing. A commitment to include psychometric assessments should be an expected part of studies utilizing these measures.

A comparison of surgery and family medicine residents' perceptions of cross-cultural care training.

The need for physicians formally trained to deliver care to diverse patient populations has been widely advocated. Utilizing a validated tool, Weissman and Betancourt's Cross-Cultural Care Survey, the aim of this current study was to compare surgery and family medicine residents' perceptions of their preparedness and skillfulness to provide high quality cross-cultural care. Past research has documented differences between the two groups' reported impressions of importance and level of instruction received in cross-cultural care. Twenty surgery and 15 family medicine residents participated in the study. Significant differences were found between surgery and family medicine residents on most ratings of the amount of training they received in cross-cultural skills. Specifically, family medicine residents reported having received more training on: 1) determining how patients want to be addressed, 2) taking a social history, 3) assessing their understanding of the cause of illness, 4) negotiating their treatment plan, 5) assessing whether they are mistrustful of the health care system and÷or doctor, 6) identifying cultural customs, 7) identifying how patients make decisions within the family, and 8) delivering services through a medical interpreter. One unexpected finding was that surgery residents, who reported not receiving much formal cultural training, reported higher mean scores on perceived skillfulness (i.e. ability) than family medicine residents. The disconnect may be linked to the family medicine residents' training in cultural humility - more knowledge and understanding of cross-cultural care can paradoxically lead to perceptions of being less prepared or skillful in this area.

A comparison of adolescent methamphetamine and other substance users in Hawai'i.

Methamphetamine use continues to be a significant problem for adolescents in Hawai'i, especially among Native Hawaiians and other Asian and Pacific Islanders. However, no research has compared the unique characteristics of these methamphetamine (MA) users to other substance users, which could contribute to enhanced treatment approaches. Utilizing a sample of adolescent treatment clients, this study compared those who have ever used and those who have never used methamphetamines on various domains. Results showed that girls were significantly more likely to use methamphetamines than other substances. Native Hawaiians and other Pacific Islanders were more likely to use methamphetamines as well, although the difference was not statistically significant. MA users reported significantly more homelessness and prior treatment episodes. While no differences were found in arrest rates or days in jail/prison/juvenile detention in the past 90 days, MA users scored significantly higher on all self-reported crime indices. MA users also scored significantly higher on all substance problem and mental health indices, and reported significantly poorer health. Implications for future research and treatment are discussed.

Corroborative study on maize quality, dry-milling and wet-milling properties of selected maize hybrids.

A corroborative study was conducted on the maize quality properties of test weight, pycnometer density, tangential abrasive dehulling device (TADD), time-to-grind on the Stenvert hardness tester (SHT), 100-kernel weight, kernel size distribution, and proximate composition as well as maize dry- and wet-millability by six participating laboratories. Suggested operating procedures were given to compare their measurements and provide the variance structure within and between laboratories and hybrids. Partial correlation coefficient among maize quality properties varied among laboratories. The repeatability and reproducibility precision values were acceptably low for the physical quality tests, except for TADD and SHT time-to-grind measurements. The yields of dry- and wet-milled products and their correlation with maize quality properties were dependent on the collaborating laboratory. This paper highlights the importance of laboratory variation when considering which maize hybrids are best suited for dry-milling and wet-milling.

Gone, But Not Forgotten? Survey of Resident Attitudes Toward a Cultural Standardized Patient Examination for a General Surgery Residency Program.

Purpose: Various tools have been utilized for cultural competency training in residency programs, including cultural standardized patient examinations. However, it is unknown whether residents feel the training they received has a long-term impact on how they care for patients. The purpose of this study was to assess whether surgical residents who participated in a cultural standardized patient examination view the experience as beneficial. Methods: Surgical residents who completed a standardized patient examination from Fall 2009 to Spring 2015 were asked to complete a 13-question survey assessing the following: (1) did participants feel prepared when dealing with patients from different cultural backgrounds, (2) did they feel the standardized patient experience was beneficial or improved their ability to care for patients, and (3) did they perceive that cultural competence was important when dealing with patients. Results: Sixty current/former residents were asked to participate and 24 (40%) completed the survey. All agreed cross-cultural skills were important and almost all reported daily interaction with patients from different cultural backgrounds. Sixteen participants (67%) reported the cultural standardized patient examination aided their ability to care for culturally dissimilar patients, and 13 (54%) said the training helped improve their communication skills with patients. Thirteen (54%) reported they would participate in another cultural standardized patient examination. Conclusion: Development of effective cultural competency training remains challenging. This study provides some preliminary results that demonstrate the potential lasting impact of cultural competency training. Participants found the skills gained from cultural standardized patient examinations helpful.

Gelatinization and solubility of corn starch during heating in excess water: new insights.

Starch gelatinization is associated with the disruption of granular structure causing starch molecules to disperse in water. This study was designed to examine starch granules as they were heated in water, and their resulting morphological, structural, and solubility traits. The results indicate that starch gelatinization is a more complex process than the previously suggested order-to-disorder transition. The energy absorbed by the granules facilitates the rearrangement or formation of new bonds among molecules prior to the temperatures normally associated with the melting of amylopectin crystallites during gelatinization. It is also evident that amylose plays an important role during the initial stages of corn starch gelatinization.

Review of pesticide education materials for health care providers providing care to agricultural workers.

CONTEXT: Pesticide exposure is an important environmental and occupational health risk for agricultural workers and their families, but health care providers receive little training in it. OBJECTIVE: To evaluate the medical resources available to providers caring for patients, particularly farmworkers, exposed to pesticides and to recommend a selective bibliography for use in educating clinicians about pesticides and health care. These resources are divided into 3 domains: (1) the working knowledge, (2) the skill set, and (3) the references needed to care for these patients. METHODS: We searched library databases dating back to 1995, as well as conference materials and Internet resources. Materials were included only if they were readily available through customary sources. Materials were randomly divided into 2 groups. Two authors wrote detailed reviews for each group. The remaining authors read each document and review, making changes that were agreed upon by the team. Review procedures were standardized to examine the contemporary relevance, quality, and overall strengths and weaknesses of the material relative to guidelines developed for each domain. These guidelines were developed from the authors' experience, national focus groups, and literature review. RESULTS: While no 1 resource adequately addresses all needs, a number of resources were identified addressing the categories of working knowledge, skill set, and reference materials. Few of the reviewed materials address the cultural competence of providers treating farmworkers. Additional education resources are needed.

The indirect detection of bleach (sodium hypochlorite) in beverages as evidence of product tampering.

Bleach (sodium hypochlorite) has been identified as the adulterant in a relatively large number of product tamperings that have been investigated by the Forensic Chemistry Center (FCC) of the U.S. Food and Drug Administration. In this work, household bleach was added to 23 different beverages at each of three levels. The impact of sodium hypochlorite on these beverages over a 13-day study period was evaluated using the following techniques: diphenylamine spot test for oxidizing agents, potassium iodide-starch test paper for oxidizing agents, pH, iodometric titration for quantitating hypochlorite, ion chromatography for chloride and chlorate quantitation, automated headspace sampling with gas chromatography-flame ionization detection (GC-FID) for determination of chloroform, and visual and organoleptic observations. This study has shown that hypochlorite is fragile when added to most common beverages and typically breaks down either partially or completely over time. In cases where a beverage is suspected of being adulterated with bleach but tests for hypochlorite are negative, it is still possible to characterize the product to demonstrate that the results are consistent with the addition of bleach. An adulterated product will give a positive test for oxidizing agents using the diphenylamine spot test. It is likely that the pH of the adulterated product will be higher than a control of that product. Ion chromatographic analysis shows elevated chloride and chlorate as compared with a control. And, chloroform may also be detected by GC-FID especially if the beverage that was adulterated contains citric acid.

The determination of nicotine and sulfate in supermarket ground beef adulterated with Black Leaf 40.

In December 2002, approximately 250 lbs. of ground beef was adulterated with nicotine sulfate by a supermarket employee and subsequently sold to the public. Soon afterward, reports of illness associated with ground beef purchased at a single store were identified. Authorities suspected the ground beef was tainted with Black Leaf 40, a banned pesticide containing approximately 40% nicotine as nicotine sulfate. Ground beef submitted to our laboratory was analyzed in concert by high performance liquid chromatography-ultraviolet detection (HPLC-UV), gas chromatography-mass spectrometry (GC-MS), and high performance anion exchange chromatography with suppressed conductivity detection. GC-MS was used to identify the samples that contained nicotine. The nicotine was confirmed and quantitated by HPLC-UV. The sulfate was identified and quantitated by high performance anion exchange chromatography with suppressed conductivity detection. Our analysis revealed that the raw tainted beef contained about 350 mg/kg nicotine free base, a potentially lethal dose of nicotine per serving for an adult. Additionally, we found elevated sulfate levels in the samples that tested positive for nicotine, providing evidence that nicotine sulfate was the probable adulterant.

Melanocortin receptor accessory proteins in adrenal disease and obesity.

Melanocortin receptor accessory proteins (MRAPs) are regulators of the melanocortin receptor family. MRAP is an essential accessory factor for the functional expression of the MC2R/ACTH receptor. The importance of MRAP in adrenal gland physiology is demonstrated by the clinical condition familial glucocorticoid deficiency type 2. The role of its paralog melanocortin-2-receptor accessory protein 2 (MRAP2), which is predominantly expressed in the hypothalamus including the paraventricular nucleus, has recently been linked to mammalian obesity. Whole body deletion and targeted brain specific deletion of the Mrap2 gene result in severe obesity in mice. Interestingly, Mrap2 complete knockout (KO) mice have increased body weight without detectable changes to food intake or energy expenditure. Rare heterozygous variants of MRAP2 have been found in humans with severe, early-onset obesity. In vitro data have shown that Mrap2 interaction with the melanocortin-4-receptor (Mc4r) affects receptor signaling. However, the mechanism by which Mrap2 regulates body weight in vivo is not fully understood and differences between the phenotypes of Mrap2 and Mc4r KO mice may point toward Mc4r independent mechanisms.

Agricultural and residential pesticides in wipe samples from farmworker family residences in North Carolina and Virginia.

Children of farmworkers can be exposed to pesticides through multiple pathways, including agricultural take-home and drift as well as residential applications. Because farmworker families often live in poor-quality housing, the exposure from residential pesticide use may be substantial. We measured eight locally reported agricultural pesticides and 13 pesticides commonly found in U.S. houses in residences of 41 farmworker families with at least one child < 7 years of age in western North Carolina and Virginia. Wipe samples were taken from floor surfaces, toys, and children's hands. We also collected interview data on possible predictors of pesticide presence, including characteristics of the household residents, cleaning practices, and characteristics of the home. All families were Spanish-speaking, primarily from Mexico. Results indicate that six agricultural and 11 residential pesticides were found in the homes, with agricultural, residential, or both present in 95% of homes sampled. In general, residential pesticides were more commonly found. Presence of both types of pesticides on the floor was positively associated with detection on toys or hands. Agricultural pesticide detection was associated with housing adjacent to agricultural fields. Residential pesticide detection was associated with houses judged difficult to clean. Although the likelihood of agricultural pesticide exposure has been considered high for farmworker families, these results indicate that residential pesticide use and exposure in this population merit further study.

The refinement of a cultural standardized patient examination for a general surgery residency program.

BACKGROUND: Recent articles have documented the importance of cultural competency in surgery. Surgical residency programs have used the Objective Structured Clinical Examinations or cultural standardized patient examinations as a training tool. Past studies evaluating cultural competency have noted the importance of including an observational (control) arm, which would allow for a more objective assessment of a resident's competency in this area. The purpose of our article is to present the results of a follow-up study to a pilot cultural standardized patient examination for surgery residents. METHODS: All first-year surgery residents were required to participate in the videotaped cultural SP examination as part of the general surgery residency curriculum. Two measures were used to assess resident performance. On the day of the examination, the Cross-Cultural Care Survey was administered. The examination was assessed by the residents themselves, faculty observers, and standardized patients, using a written checklist that was developed to evaluate residents on all 6 Accreditation Council for Graduate Medical Education competencies. RESULTS: The current study includes 20 first-year surgery residents from academic years 2011 to 2012 and 2012 to 2013. The examination of pretest differences in groups found that students born outside of the United States had significantly higher scores on attitude (t = -2.68, df = 18, p = 0.02), but no statistically significant differences were found in skillfulness or knowledge or in the overall rating scale. For the overall rating scale, change from pretest to posttest was statistically significant (t = -2.25, df = 18, p = 0.04). Further analysis revealed that students who were born in the United States demonstrated a significant increase in ratings (t = -3.08, df = 10, p = 0.01) whereas students who were not born in the United States showed little change (t = -0.35, df = 7, p = 0.74). These results show that the means in attitude scales changed little for all groups, but both white and US-born students showed greater improvement on skillfulness and knowledge. CONCLUSIONS: Training and measurement of cross-cultural health care skills remains challenging. However, studies like these provide a good starting point from which to build.
