Assessing nutrition literacy and nutrition counseling proficiency following an interdisciplinary culinary medicine elective.

CONTEXT: Culinary medicine (CM) is a growing field of education that aims to bridge the gap between the clinical need for nutritional counseling and the lack of education on the topic. Healthcare professionals can aid in nutrition-related noncommunicable disease (NCD) prevention by improving a patient's dietary behavior. However, the presence of nutrition education in healthcare curricula is lacking. Early evidence indicates that CM could address this gap. OBJECTIVES: The objectives of this study are to determine if the provision of an interdisciplinary CM elective will improve student knowledge and confidence with counseling on nutrition and culinary principles, and to improve personal dietary habits of students. METHODS: This was a one-group pretest-posttest quasi-experimental design. First- and second-year osteopathic medical students (OMS) and nurse practitioner students were recruited to participate in a CM elective via email. Participants were excluded if they were not in good academic standing at their respective institutions. Twelve individuals (n=8 medical; n=4 nursing) were enrolled in the course. Participants completed pre- and postcourse surveys to determine changes in nutrition literacy (Nutrition Literacy Assessment Instrument [NLit42]), nutrition counseling proficiency (Nutrition Survey for Family Practitioners), and dietary quality (Automated Self-Administered 24-h dietary assessment tool; ASA24®). A two-sided, paired t test was conducted to determine changes in outcome variables. RESULTS: All 12 participants completed the precourse assessments, and 8 participants completed the postcourse assessments. Culinary activity attendance was 94.5 %. Participants exhibited a statistically significant increase in their overall nutrition literacy scores after completing the CM elective (p=0.006). Literacy subcategories indicated that the improvement came from the participant's ability to understand household measurements (p=0.005) better. Increases in self-reported proficiency were observed for participants' confidence to counsel on nutrition and prevention/wellness (p=0.02) and macronutrients in health and food safety (p=0.01). No statistically significant changes in the personal dietary pattern or quality were observed. CONCLUSIONS: The interdisciplinary CM elective improved nutrition literacy and some aspects of counseling proficiency. Although small shifts in dietary variables were observed, the elective did not statistically improve participants' dietary pattern. However, some changes that were observed may lead to clinically relevant outcomes if maintained long-term. These findings are encouraging. Implementing CM as an educational tool could improve healthcare practitioners' ability to understand and counsel patients on nutrition to prevent the nutrition-related NCDs.

Food Intake, Source, and Planning and Shopping Behavior Differences Among Hispanic, White, Black, and Asian Females.

BACKGROUND: Abdominal obesity remains a high public health concern. Within the United States, there are noted disparities among different ethnic/racial groups in relation to obesity, especially for females. PURPOSE: The purpose of this secondary analysis project was to examine the differences in nutritional intake, food sources, and meal planning and food shopping between Hispanic, White, Black, and Asian females by abdominal obesity level in the United States. METHODS: The 2017-2018 National Health Nutrition Examination data was used. Major variables included race/ethnicity, waist circumference (WC), nutritional intake, food source, and food shopping and meal planning behaviors. Descriptive statistics, correlational analyses, a series of two-way factorial analysis of variance, and odds ratio analyses were conducted to address research questions. FINDINGS: When comparing nutritional intake and food source by different racial/ethnic groups and abdominal obesity level, there were no interaction effects for all categories across groups. However, for the racial/ethnic main effects and obesity main effects, significant differences among groups were noted for nutritional intake and food source categories. There were no differences in food shopping and meal preparation between abdominal obesity and non-obese participants in each racial/ethnic group. CONCLUSIONS: Similarities and differences were noted between racial/ethnic groups for nutritional intake and sources of food. However, no significant differences were noted between racial/ethnic groups for food shopping and meal preparation behaviors. More research should be done to confirm these findings and further understand food shopping and meal preparation behaviors.

University campus breastfeeding, knowledge, and perceptions of support: An exploratory study.

Breastfeeding is often considered principally a biological issue but success is impacted by the socio-ecological environment of the lactating parent. Identifying current attitudes towards breastfeeding is essential in the effort toward normalizing breastfeeding in communities, including university campuses. The study explored campus community knowledge, awareness, and attitudes about breastfeeding, including available resources and applicable laws on two university campuses in the southern United States. This cross-sectional, self-reporting study utilized the Iowa Infant Feeding Attitude Scale and an adaptation of the Breastfeeding Behavior Questionnaire to survey a convenience sample. Results revealed decreased awareness of protective laws, availability of private lactation space, and insufficient public appreciation of breastfeeding's unique advantages to both lactating parent and infant as barriers to breastfeeding. These findings will help develop additional breastfeeding strategies to improve university campus community breastfeeding initiatives.

Pharmacy-based immunization in rural USA during the COVID-19 pandemic: A survey of community pharmacists from five southeastern states.

INTRODUCTION: Immunization rates for seasonal and non-seasonal vaccines dropped during the COVID-19 pandemic. Little is known about the extent to which community pharmacies in the USA continued to serve as immunization sites during the pandemic. This study compared 1) the types and perceived changes in non-COVID-19 vaccine doses administered at rural community pharmacies in 2020 (during the pandemic) to 2019 (pre-pandemic) and 2) the delivery of non-COVID-19 immunization services in 2020 to 2019. METHODS: A mixed-mode (paper/electronic) survey of a convenience sample of 385 community pharmacies operating in rural settings and have administered ≥1 vaccine in 2019 and 2020 was distributed in May-August 2021. Survey development was informed by relevant literature, pre-tested with three individuals, and pilot-tested with 20 pharmacists. Non-response bias was assessed, and survey responses were analyzed using descriptive and bivariate statistics. RESULTS: Of the 385 community pharmacies, 86 qualified pharmacies completed the survey (Response Rate = 23.8%). The percentage of pharmacies offering a given vaccine in 2019 and 2020 were similar; with one exception, a higher percentage of pharmacies reported having MMR administered for adults in the pharmacy in 2020 (McNemar's test; p-value = 0.0253). For each given vaccine, the majority of respondents did not perceive a change in the number of doses administered in 2020 compared to 2019. Further, the majority reported no difference in how they delivered immunization services during and pre-pandemic. However, a small percentage of respondents (6.0-22.0%) adapted their services by adopting several measures to ensure the safety and continuity of immunizations during the pandemic. CONCLUSION: Findings highlight the importance of community pharmacies as immunization sites during the pandemic. Community pharmacies continued immunization delivery at community pharmacies during the pandemic with almost no noticeable change to types and doses of vaccines compared to pre-pandemic nor the process of vaccine delivery.

An Elastic Organic Crystal Enables Macroscopic Photoinduced Crystal Elongation.

Among the various types of photomechanical deformations of organic crystals, photoinduced elongation of millimeter-scale crystals has yet to be demonstrated. Here we report that the millimeter-sized crystalline rods of an anthracene-pentiptycene hybrid organic π-system (1) are highly elastic and able to elongate up to 21.6% or 0.40 mm without fragmentation upon undergoing [4 + 4] photodimerization reactions. Both the mechanical and photomechanical effects reveal a strong cohesion of the system, even at the interface of 1 and its photodimer 2 and under the conditions of randomized molecular packing, representing a new class of mechanically adaptive organic crystals.

Cellular and Molecular Biology of Cancer Stem Cells of Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death globally. The cancer stem cells (CSCs) of HCC are responsible for tumor growth, invasion, metastasis, recurrence, chemoresistance, target therapy resistance and radioresistance. The reported main surface markers used to identify liver CSCs include epithelial cell adhesion/activating molecule (EpCAM), cluster differentiation 90 (CD90), CD44 and CD133. The main molecular signaling pathways include the Wnt/ß-catenin, transforming growth factors-ß (TGF-ß), sonic hedgehog (SHH), PI3K/Akt/mTOR and Notch. Patients with EpCAM-positive alpha-fetoprotein (AFP)-positive HCC are usually young but have advanced tumor-node-metastasis (TNM) stages. CD90-positive HCCs are usually poorly differentiated with worse prognosis. Those with CD44-positive HCC cells develop early metastases. Those with CD133 expression have a higher recurrence rate and a shorter overall survival. The Wnt/ß-catenin signaling pathway triggers angiogenesis, tumor infiltration and metastasis through the enhancement of angiogenic factors. All CD133+ liver CSCs, CD133+/EpCAM+ liver CSCs and CD44+ liver CSCs contribute to sorafenib resistance. SHH signaling could protect HCC cells against ionizing radiation in an autocrine manner. Reducing the CSC population of HCC is crucial for the improvement of the therapy of advanced HCC. However, targeting CSCs of HCC is still challenging.

Exploring outcomes from an innovative, pediatric-focused intervention with undergraduate nursing students.

BACKGROUND: To adapt to COVID-19 restrictions, a virtual pediatric skills day was developed to provide nursing students with practical experience prior to entering the pediatric clinical setting. Student assessment before and after participation indicate a virtual skills day is helpful in building student confidence prior to pediatric clinicals. METHODS: This mixed-method study involved a cross-sectional approach with a six-item survey administered before and immediately after the virtual pediatric skills day intervention to undergraduate junior nursing students. Outcome measures included comfort and preparation for pediatrics and families of pediatric patients. FINDINGS: After exploring outcomes from 93 students complete pre and post intervention measures, we addressed comfort themes including excited, nervous, and readiness while preparedness themes highlighted concerns with parental interactions, upset children, and COVID-19 restrictions. DISCUSSION: It is beneficial for nursing students to have clinical experiences with children prior to visiting a pediatric clinical setting. Such experiences decrease student stress and anxiety and allow meaningful opportunities to occur.

Shaken Baby Syndrome Education for Mothers Awaiting Appointments in Rural OB/GYN Office.

A partnership between a nursing program and a rural obstetric office provided education to pregnant and postpartum women about coping with infant crying and the dangers of shaking a baby. Undergraduate nursing students delivered the Period of PURPLE Crying (PURPLE) educational program to 148 mothers. Change in knowledge about infant crying and the community clinical experience was evaluated. Pre and post intervention data were collected. Descriptive statistics indicated higher scores on mothers' posttest for knowledge about normal newborn crying behaviors and coping strategies. Students further developed the role of educator and researcher. These findings suggest the intervention contributed to mothers' improved knowledge about infant crying. Results of the pilot study are encouraging because the intervention had a significant effect on mothers' knowledge about infant crying and Shaken Baby Syndrome (SBS).

Impact of a Multicomponent Educational Intervention on Community Pharmacy-Based Naloxone Services Implementation: A Pragmatic Randomized Controlled Trial.

BACKGROUND: Despite US naloxone access laws, community pharmacists lack training and confidence in providing naloxone. OBJECTIVE: To assess the impact of the Empowering Community Pharmacists program on pharmacists' knowledge, perceived barriers, attitudes, confidence, and intentions regarding naloxone services implementation, as well as naloxone prescriptions dispensed. METHODS: A 3-month pragmatic randomized controlled trial was conducted from December 2018 to March 2019. Alabama community pharmacists were recruited by mail, email, phone, and fax and randomized to intervention (monthly resources/reminders + educational webinar) or control (monthly reminders only). Outcome measures were assessed via online surveys at baseline (T1), immediately post-intervention (T2), and 3 months post-intervention (T3), including naloxone knowledge (%correct); perceived barriers, attitudes, confidence, and intention regarding naloxone services implementation (7-point Likert-type scale; 1 = strongly disagree, 7 = strongly agree); and number of naloxone prescriptions dispensed. Mean differences between control and intervention from T1 to T3 were assessed using 2-way mixed analysis of variance and adjusted analyses were conducted using generalized estimating equations with negative binomial distribution to assess associations between variables. RESULTS: Of 55 participants (n = 27 intervention, n = 28 control), most were female (80.3%), white (80.6%), in independently owned pharmacies (39.1%). Increases in mean [SD] confidence (5.52 [1.03]-6.16 [0.74], P < 0.0005) and intention (5.35 [1.51]-6.10 [0.96], P = 0.023) occurred from pre- to post-program within the intervention group and were statistically significant compared with control (confidence P = 0.016, intention P = 0.014). Confidence (exp(ß) = 1.46, P = 0.031) and perceived barriers (exp(ß) = 0.75, P = 0.022) were associated with number of naloxone prescriptions dispensed. CONCLUSION AND RELEVANCE: The Empowering Community Pharmacists program improved community pharmacists' confidence and intention regarding naloxone services implementation. Other states can adapt program elements according to their laws. CLINICALTRIALS.GOV IDENTIFIER: NCT05093309.

Impact on social capital and learning engagement due to social media usage among the international students in the U.S.

International students who pursue their academic goals in United States are prone to difficulties when attempting to build social resources and adjust to the new culture. Social media is a practical means of connection due to its ease of use and accessibility. Previous research has indicated contradictory effects of social media use on academic engagement. In addition to the direct effect, this research examined social media use influences on international students' learning engagement by mediating social capital and cultural adjustment. A total of 209 international students completed a web-based survey distributed via e-mail and social media between November 2021 and May 2022. Data were analyzed using Structural Equation Model. Results showed that only purposely using social media to collaborate with learning counterparts or materials directly improves international students' learning engagement. Other uses of social media (e.g., expanding new resources, solidifying close relationships) have no significant direct effects. Nonetheless, they are essential to improving levels of learning engagement via the mediation of bridging capital (social resources attributed to expanding relationships) and students' cultural adjustment in the U.S. International students' bonding capital (social resources available through trustworthy relationships) and home cultural retention showed little direct or indirect effects on learning engagement. This study recognizes the importance of social resources and cultural adjustment for international students. Also, this study provides valuable information to educators and administrators, as there is a need to identify the underlying mechanisms to contribute feasible learning intervention approaches and alleviate negative effects for international students.

Upper Gastrointestinal Cancer and Liver Cirrhosis.

The extended scope of upper gastrointestinal cancer can include esophageal cancer, gastric cancer and pancreatic cancer. A higher incidence rate of gastric cancer and esophageal cancer in patients with liver cirrhosis has been reported. It is attributable to four possible causes which exist in cirrhotic patients, including a higher prevalence of gastric ulcers and congestive gastropathy, zinc deficiency, alcohol drinking and tobacco use and coexisting gut microbiota. Helicobacter pylori infection enhances the development of gastric cancer. In addition, Helicobacter pylori, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans also contribute to the development of pancreatic cancer in cirrhotic patients. Cirrhotic patients (especially those with alcoholic liver cirrhosis) who undergo liver transplantation have a higher overall risk of developing de novo malignancies. Most de novo malignancies are upper gastrointestinal malignancies. The prognosis is usually poor. Considering the surgical risk of upper gastrointestinal cancer among those with liver cirrhosis, a radical gastrectomy with D1 or D2 lymph node dissection can be undertaken in Child class A patients. D1 lymph node dissection can be performed in Child class B patients. Endoscopic submucosal dissection for gastric cancer or esophageal cancer can be undertaken safely in selected cirrhotic patients. In Child class C patients, a radical gastrectomy is potentially fatal. Pancreatic radical surgery should be avoided in those with liver cirrhosis with Child class B or a MELD score over 15. The current review focuses on the recent reports on some factors in liver cirrhosis that contribute to the development of upper gastrointestinal cancer. Quitting alcohol drinking and tobacco use is important. How to decrease the risk of the development of gastrointestinal cancer in those with liver cirrhosis remains a challenging problem.

Experimental demonstration of noncontact vital-sign measurement using pulse radar.

BACKGROUD: Recently, monitoring the vital-sign with the noncontact method is a popular technology. OBJECTIVE: In this work, we present a fully pulse radar system including front-end sensing and back-end data processing. A series of ultra-wide band sensing pulses is generated and radiated to detect the subject's chest vibration which in turn obtains the required vital-sign signals. METHODS: An artificial plywood with 3 centimeter thickness is placed between a transmitting/receiving antenna of the radar and subject to demonstrate the characteristic of noncontact sensing. The firmware and digital signal processing are also presented in this paper to optimize physiological data quality. RESULTS: The experimental results show that the continuous heart rate and breathing rate can be monitored by this customized system radar module. CONCLUSION: A fully customized ultra-wide band radar for vital-sign application is presented. The radar system plan with wall parameter is also incorporated into the design consideration to meet the FCC requirement and SNR.

Mental Health and Psychotropic Stigma Among Student Pharmacists.

Objective: To gain a better understanding of student pharmacists' stigma toward mental health and psychotropic medications. Methods: A cross-sectional study was conducted via paper and online surveys amongst all student pharmacists enrolled in a Doctor of Pharmacy program in the Southeastern United States (n = 501). The Perceived Devaluation and Discrimination (PDD) Scale was used to measure mental health stigma. The Beliefs about Medicines Questionnaire (BMQ) was modified to measure psychotropic stigma. MANOVAs were conducted to investigate relationships between student pharmacists' characteristics with mental health and psychotropic stigma. A paired t-test was used to determine if there was a difference between degree of mental health stigma and psychotropic stigma. Results: A total of 390 participants completed the survey (65%). The sample was mostly female (67%), white (79%), and non-Hispanic (96%). Ages were predominantly within the 19-24-year range (80%), and the majority of respondents reported previous interactions with patients who have mental health conditions (55%) or patients on psychotropic medications (65%). Student personal preferences for mental health treatment were primarily psychologic (42%) or both psychologic and psychotropic (40%). Degree of psychotropic stigma was significantly greater than that of mental health stigma. A statistically significant association was found between student personal preference for treatment and the psychotropic stigma. No difference was found in degree of either type of stigma across cohorts. Conclusions: Student pharmacists demonstrated both mental health and psychotropic stigmas. Future research should be performed to determine what effects these stigmas have on care of patients with mental health conditions.

Pre-service Teachers Perspectives of Google Expedition.

This article explores pre-service teachers' personal experiences as they implemented immersive virtual reality using Google Expedition during a summer STEM camp for primary students. The research is situated around semi-structured interviews conducted to determine how pre-service teachers view their experiences using Google Expedition in primary classrooms, and the pedagogical challenges they encountered during this process. The semi-structured interviews provided insight into the planning, the pedagogical applications, and the obstacles or challenges they encountered during the planning stage and execution of their lesson using a highly interactive, three-dimensional tool such as Google Expedition. The data indicated that pre-service teachers had confidence in implementing virtual reality lessons in the class and considered it a new horizon for teaching. Yet, it also identified pedagogical challenges associated with implementing virtual reality in a primary classroom.

A classification algorithm to predict chronic pain using both regression and machine learning - A stepwise approach.

This secondary data analysis study aimed to (1) investigate the use of two sense-based parameters (movement and sleep hours) as predictors of chronic pain when controlling for patient demographics and depression, and (2) identify a classification model with accuracy in predicting chronic pain. Data collected by Oregon Health & Science University between March 2018 and December 2019 under the Collaborative Aging Research Using Technology Initiative were analyzed in two stages. Data were collected by sensor technologies and questionnaires from older adults living independently or with a partner in the community. In Stage 1, regression models were employed to determine unique sensor-based behavioral predictors of pain. These sensor-based parameters were used to create a classification model to predict the weekly recalled pain intensity and interference level using a deep neural network model, a machine learning approach, in Stage 2. Daily step count was a unique predictor for both pain intensity (75% Accuracy, F1 = 0.58) and pain interference (82% Accuracy, F1 = 0.59). The developed classification model performed well in this dataset with acceptable accuracy scores. This study demonstrated that machine learning technique can be used to identify the relationship between patients' pain and the risk factors.

Rapid Detection of Gut Microbial Metabolite Trimethylamine N-Oxide for Chronic Kidney Disease Prevention.

The gut microbiota plays a critical role in chronic kidney disease (CKD) and hypertension. Trimethylamine-N-oxide (TMAO) and trimethylamine (TMA) are gut microbiota-derived metabolites, and both are known uraemic toxins that are implicated in CKD, atherosclerosis, colorectal cancer and cardiovascular risk. Therefore, the detection and quantification of TMAO, which is a metabolite from gut microbes, are important for the diagnosis of diseases such as atherosclerosis, thrombosis and colorectal cancer. In this study, a new "colour-switch" method that is based on the combination of a plasma separation pad/absorption pad and polyallylamine hydrochloride-capped manganese dioxide (PAH@MnO2) nanozyme was developed for the direct quantitative detection of TMAO in whole blood without blood sample pretreatment. As a proof of concept, a limit of quantitation (LOQ) of less than 6.7 µM for TMAO was obtained with a wide linear quantification range from 15.6 to 500 µM through quantitative analysis, thereby suggesting potential clinical applications in blood TMAO monitoring for CKD patients.

Student Perceptions of a Cardiac Skills Laboratory Using a Just-in-Time Teaching Approach.

BACKGROUND: Clinical instructors noted students in an advanced medical-surgical nursing course frequently struggled to identify cardiac rhythms in clinical settings. Course faculty redesigned a skills lab incorporating the Just-in-Time Teaching (JiTT) teaching approach, which was selected to guide teaching practices and encourage interactions among students and faculty during the lab. METHOD: This mixed-methods study examined student perceptions of implementing JiTT to enhance learning. Data were collected through the use of a questionnaire that included 10 Likert-type and four open-ended questions completed by 269 baccalaureate nursing students. RESULTS: Students provided high evaluative remarks regarding the teaching approach. The following four themes were noted from qualitative data: assessed prior knowledge, student-centered, interactive, and provided clarity. CONCLUSION: Students reported incorporation of a JiTT skills lab provided an effective approach to gain a greater understanding of cardiac rhythms and prepare for clinical practice.

Aspirin Modifies Inflammatory Mediators and Metabolomic Profiles and Contributes to the Suppression of Obesity-Associated Breast Cancer Cell Growth.

Breast cancer is the most common cancer among women. Adiposity generally accompanies immune cell infiltration and cytokine secretion, which is ideal for tumor development. Aspirin is a chemopreventive agent against several types of cancer. The aim of this study was to investigate whether aspirin inhibits the growth of 4T1 breast cancer cells by inhibiting the inflammatory response and regulating the metabolomic profile of 3T3-L1 adipocytes. 3T3-L1 adipocyte-conditioned medium (Ad-CM) was used to mimic the obese adipose tissue microenvironment in 4T1 cells. The results revealed that aspirin inhibited macrophage chemoattractant protein (MCP-1), interleukin (IL-6), IL-1ß, and plasminogen activator inhibitor (PAI-1) production in 3T3-L1 adipocytes stimulated by tumor necrosis factor-alpha (TNF-α) and lipopolysaccharide (LPS). In the obesity-associated model, Ad-CM significantly promoted 4T1 cell growth and migration, which were attenuated after aspirin treatment. The results of metabolic analyses using Ad-CM showed that amino acid metabolites and oxidative stress were increased in mature 3T3-L1 adipocytes compared to those in fibroblasts. Aspirin treatment modified metabolites involved in suppressing lipogenesis, oxidative stress, and neoplastic formation. In the relative fatty acid quantitation analysis of Ad-CM, aspirin diminished fatty acid contents of C16:1, C18:1, C18:2, C20:4, and C24:1. This study is the first to show that aspirin modifies the metabolomics and fatty acid composition of 3T3-L1 adipocytes and inhibits obesity-associated inflammation that contributes to obesity-related breast cancer cell growth and migration.
