The persistent threat of emerging plant disease pandemics to global food security.

Plant disease outbreaks are increasing and threaten food security for the vulnerable in many areas of the world. Now a global human pandemic is threatening the health of millions on our planet. A stable, nutritious food supply will be needed to lift people out of poverty and improve health outcomes. Plant diseases, both endemic and recently emerging, are spreading and exacerbated by climate change, transmission with global food trade networks, pathogen spillover, and evolution of new pathogen lineages. In order to tackle these grand challenges, a new set of tools that include disease surveillance and improved detection technologies including pathogen sensors and predictive modeling and data analytics are needed to prevent future outbreaks. Herein, we describe an integrated research agenda that could help mitigate future plant disease pandemics.

Deep Learning Assistance Closes the Accuracy Gap in Fracture Detection Across Clinician Types.

BACKGROUND: Missed fractures are the most common diagnostic errors in musculoskeletal imaging and can result in treatment delays and preventable morbidity. Deep learning, a subfield of artificial intelligence, can be used to accurately detect fractures by training algorithms to emulate the judgments of expert clinicians. Deep learning systems that detect fractures are often limited to specific anatomic regions and require regulatory approval to be used in practice. Once these hurdles are overcome, deep learning systems have the potential to improve clinician diagnostic accuracy and patient care. QUESTIONS/PURPOSES: This study aimed to evaluate whether a Food and Drug Administration-cleared deep learning system that identifies fractures in adult musculoskeletal radiographs would improve diagnostic accuracy for fracture detection across different types of clinicians. Specifically, this study asked: (1) What are the trends in musculoskeletal radiograph interpretation by different clinician types in the publicly available Medicare claims data? (2) Does the deep learning system improve clinician accuracy in diagnosing fractures on radiographs and, if so, is there a greater benefit for clinicians with limited training in musculoskeletal imaging? METHODS: We used the publicly available Medicare Part B Physician/Supplier Procedure Summary data provided by the Centers for Medicare & Medicaid Services to determine the trends in musculoskeletal radiograph interpretation by clinician type. In addition, we conducted a multiple-reader, multiple-case study to assess whether clinician accuracy in diagnosing fractures on radiographs was superior when aided by the deep learning system compared with when unaided. Twenty-four clinicians (radiologists, orthopaedic surgeons, physician assistants, primary care physicians, and emergency medicine physicians) with a median (range) of 16 years (2 to 37) of experience postresidency each assessed 175 unique musculoskeletal radiographic cases under aided and unaided conditions (4200 total case-physician pairs per condition). These cases were comprised of radiographs from 12 different anatomic regions (ankle, clavicle, elbow, femur, forearm, hip, humerus, knee, pelvis, shoulder, tibia and fibula, and wrist) and were randomly selected from 12 hospitals and healthcare centers. The gold standard for fracture diagnosis was the majority opinion of three US board-certified orthopaedic surgeons or radiologists who independently interpreted the case. The clinicians' diagnostic accuracy was determined by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve, sensitivity, and specificity. Secondary analyses evaluated the fracture miss rate (1-sensitivity) by clinicians with and without extensive training in musculoskeletal imaging. RESULTS: Medicare claims data revealed that physician assistants showed the greatest increase in interpretation of musculoskeletal radiographs within the analyzed time period (2012 to 2018), although clinicians with extensive training in imaging (radiologists and orthopaedic surgeons) still interpreted the majority of the musculoskeletal radiographs. Clinicians aided by the deep learning system had higher accuracy diagnosing fractures in radiographs compared with when unaided (unaided AUC: 0.90 [95% CI 0.89 to 0.92]; aided AUC: 0.94 [95% CI 0.93 to 0.95]; difference in least square mean per the Dorfman, Berbaum, Metz model AUC: 0.04 [95% CI 0.01 to 0.07]; p < 0.01). Clinician sensitivity increased when aided compared with when unaided (aided: 90% [95% CI 88% to 92%]; unaided: 82% [95% CI 79% to 84%]), and specificity increased when aided compared with when unaided (aided: 92% [95% CI 91% to 93%]; unaided: 89% [95% CI 88% to 90%]). Clinicians with limited training in musculoskeletal imaging missed a higher percentage of fractures when unaided compared with radiologists (miss rate for clinicians with limited imaging training: 20% [95% CI 17% to 24%]; miss rate for radiologists: 14% [95% CI 9% to 19%]). However, when assisted by the deep learning system, clinicians with limited training in musculoskeletal imaging reduced their fracture miss rate, resulting in a similar miss rate to radiologists (miss rate for clinicians with limited imaging training: 9% [95% CI 7% to 12%]; miss rate for radiologists: 10% [95% CI 6% to 15%]). CONCLUSION: Clinicians were more accurate at diagnosing fractures when aided by the deep learning system, particularly those clinicians with limited training in musculoskeletal image interpretation. Reducing the number of missed fractures may allow for improved patient care and increased patient mobility. LEVEL OF EVIDENCE: Level III, diagnostic study.

High School FLASH Sexual Health Education Curriculum: LGBTQ Inclusivity Strategies Reduce Homophobia and Transphobia.

Homophobic and transphobic beliefs that lead to bias-based harassment remain a critical concern for young people in the USA. The aim of the present study was to examine the impact of an inclusive comprehensive sex education program (High School FLASH) on homophobic and transphobic beliefs. Data from this study come from a randomized controlled trial that evaluated the impact of High School FLASH on students' sexual behaviors and related outcomes with 20 schools in two U.S. regions (Midwest and South). Following the baseline survey, the 20 schools were randomly assigned to receive FLASH or a comparison curriculum. Ninth and 10th grade students completed follow-up surveys 3 and 12 months after the instructional period. We examined changes in homophobic beliefs using multilevel linear regression models in the full sample and two sub-groups: straight cisgender young people versus those who identified as not straight or cisgender. Mean scores on the homophobic and transphobic beliefs scale were statistically significantly lower among young people receiving FLASH relative to the comparison at both the 3- and 12-month timepoints (p-values for adjusted mean differences were < 0.01, n = 1357 and 1275, respectively). Specifically, FLASH's positive impact on reducing homophobic and transphobic beliefs was statistically significant for straight and cisgender youth at both survey follow-ups (p < 0.01, n = 1144 and p = 0.05, n = 1078, respectively); the effects for the LGBTQ sub-group reached statistical significance at only the final follow-up (p = 0.01, n = 197). Our results show that carefully designed, inclusive comprehensive sexual health education programs like High School FLASH can play a role in promoting better school climates for all youth by reducing beliefs that may lead to bullying, violence, and victimization.

Condom Use and Error Experience Among Young Adolescents: Implications for Classroom Instruction.

We examine condom failure and use error experienced by high school youth in two regions of the United States. Data are from a baseline survey of a randomized controlled trial to evaluate FLASH, a sexual health education curriculum for high school students. Participants were 1,597 ninth- or 10th-grade students in health class who had parental consent and who assented to participate in the study. This study examines condom use behavior among students who reported vaginal or anal sex at baseline. Of the 222 participants who reported having vaginal or anal sex in the 3 months prior to baseline survey, 180 of them reported using a condom at least once. Of these youth, 70.6% reported that they did not squeeze the tip of the condom before sex, 25.0% of youth reported that they did not roll the condom all the way down to the base of the penis, and 49.4% reported that they did not hold the base of the penis when pulling out; 36.9% reported experiencing condom breakage or slippage. The frequency of condom error and/or failure reported by young adolescents in this study indicates a need for further education on potential condom use errors with an emphasis on the correct steps for using a condom to prevent condom failure. High rates of error and failure suggest an opportunity for educators to tailor preexisting condom use interventions to further reinforce the skills necessary for effective condom use and to educate on what to do in the event of condom failure.

You-Me-Us: Results of a Cluster Randomized Trial of a Healthy Relationships Approach to Sexual Risk Reduction.

By middle adolescence, most young people have been involved in at least one romantic relationship, a context in which many sexual interactions occur. Indeed, researchers have suggested the importance of attending to relationships in programs focused on sexual risk, yet few evidence-based programs have a strong relationships focus. Our study examined the impact of a healthy relationship program called You-Me-Us that included a classroom curriculum and a school-wide peer norms approach. We evaluated the intervention using a small group randomized trial that included nine participating urban middle schools (defined as schools that include grades 6-8) in three urban school districts. We invited all 7th grade students within the study schools to enroll. Students completed three surveys during 7th and 8th grades (baseline plus two follow up surveys at 6 and 18 months following baseline). A total of 911 youth with positive consent and assent were enrolled in the study. Follow up survey response rates among those taking the baseline were 92% at 6 months and 80% at 18 months. Multilevel regression models were used to adjust for the correlation among students within the same school, and the correlation of repeated measurements taken on the same student over time. The intervention reduced vaginal sexual initiation by about half at the 6-month follow-up, and this approached significance. Further, youth in the intervention condition were less likely to believe it is okay for people their age to have vaginal sex without using condoms if the girl is on birth control. None of the remaining variables differed significantly by intervention condition. This study provides insights on using a healthy relationship approach for younger urban adolescents. This approach produced a programmatically significant reduction in sexual initiation that did not reach standard levels of statistical significance, and warrants further exploration.

Replication of It's Your Game Keep It Real! in Southeast Texas.

Despite the recent efforts of the Office of Adolescent Health to replicate programs with demonstrated efficacy, there are still few evidence-based HIV, sexually transmitted infection (STI), and teen pregnancy prevention programs that have been replicated in "real-world" settings. To test the effectiveness of It's Your Game…Keep It Real! (IYG), an evidence-based STI and pregnancy prevention program for middle schools, the curriculum was implemented by teachers in urban and suburban middle schools in Southeast Texas from 2012 to 2015. IYG was evaluated using a group-randomized wait-list controlled effectiveness trial design in which 20 middle schools in nine urban and suburban school districts in Southeast Texas were randomized equally, using a multi-attribute randomization protocol, to either the intervention condition (received IYG) (n = 10 schools comprising 1936 eligible seventh graders) or the comparison condition (received usual care) (n = 10 schools comprising 1825 eligible seventh graders). All students were blinded to condition prior to administering the baseline survey. The analytic sample comprised 1543 students (n = 804, intervention; n = 739, comparison) who were followed from baseline (seventh grade) to the 24-month follow-up (ninth grade). Multilevel regression analyses were conducted to assess behavioral and psychosocial outcomes at follow-up. There were no significant differences in initiation of vaginal or oral sex between study conditions at follow-up. However, at 12-month follow-up, compared with students in the comparison condition, students in the intervention condition reported increased knowledge, self-efficacy, and perceived favorable norms related to HIV/STIs, condoms, and/or abstinence; decreased intentions to have sex; and increased intentions to use birth control. Knowledge outcomes were statistically significant at 24-month follow-up. This IYG effectiveness trial did not replicate the behavioral effects of the original IYG efficacy trials. However, it adds to the growing literature on the replication of evidence-based programs, and underscores the need to better understand how variations in implementation, setting, and measurement affect the behavioral impact of such programs.Clinical trial registration clinicaltrials.gov (NCT03533192).

Dual Contraceptive Method Use Among Youth in Alternative Schools.

Dual contraceptive method use, or using a highly effective contraceptive method plus a barrier method like condoms, is gaining attention as a strategy for preventing unplanned pregnancy and sexually transmitted diseases. We investigated rates of dual method use among a sample of youth in urban alternative schools, and explored the relationship between dual method use and sexual partner type. The study analyzed data from 765 students enrolled in 11 district-run continuation high schools in northern California. We explored the association between dual method use and sexual partner type (steady only, a mix of steady and non-steady, and non-steady only) using logistic regression. Differences in dual rates by partner type were statistically significant, with higher rates of dual methods use reported among young people reporting non-steady sexual partners only, as compared to those with steady partners only. The data illustrate that young people in alternative school settings could gain from further intervention on the benefits, skills, and challenges of using two methods of contraception as opposed to one with both steady and non-steady sexual partners.

Observational study of kidney function and albuminuria in patients with type 2 diabetes treated with exenatide BID versus insulin glargine.

BACKGROUND: Kidney disease is common among patients with type 2 diabetes (T2DM). Treatment of diabetes seeks to minimize negative kidney impact. OBJECTIVE: To assess the changes in kidney function and incidence of albuminuria in patients with T2DM treated for 1 year with exenatide twice daily (BID) or insulin glargine. METHODS: Retrospective analyses were performed using an electronic medical record database. Patients inititating treatment with either exenatide BID or insulin glargine between November 2006, and April 2009 comprised the study cohort. The 2 groups were 1:1 propensity score matched on baseline variables yielding 2683 pairs. Measures of kidney function included estimated glomerular filtration rate (eGFR,) and urinary albumin/creatinine ratio (UACR). RESULTS: Mean baseline eGFR was identical between the groups (79 ± 23 mL/min/1.73 m(2)). At 1-year follow-up, there was no significant difference in mean eGFR between the groups (78 mL/min/1.73 m(2) for exenatide BID vs 80 mL/min/1.73 m(2) for insulin glargine; P = .39). Despite matching of multiple characteristics, mean baseline UACR was lower in the exenatide BID group (mean = 34 ± 71 mg/g) compared with the insulin glargine group (183 ± 509 mg/g; P = .03). At follow-up, exenatide BID patients had a mean increase in UACR of 104 mg/g, insulin glargine patients had a decrease of 47 mg/g, but the difference was not significant (P = .19). CONCLUSION: There were no significant differences in change in kidney function or albuminuria at 1 year in patients treated with exenatide BID compared with insulin glargine as administered in routine practice.

An exploratory study of adolescent pimping relationships.

In the last decade, public attention to the problem of commercially sexually exploited children (CSEC) has grown. This exploratory qualitative study examines adolescent pimping relationships, including how urban youth perceive these types of relationships. Study data stem from interviews with three young adult informants with first-hand knowledge of adolescent pimping, as well as three gender-specific focus group discussions with a convenience sample of 26 urban high school students who have first- or second-hand knowledge of adolescent pimping. Findings indicate that respondents believe teen pimping exists in their schools and communities, and that those exploited typically do not self-identify as victims. Respondents also believed that younger pimps are more likely to use violence to induce compliance among the girls they exploit, whereas older pimps are more likely to emotionally manipulate young women into exploitation. Further, respondents indicated that some young people agreed to exchange or sell sex for money as a favor to their boyfriends or girlfriends, and some young people believed that selling sex is acceptable under certain circumstances. The growing attention to CSEC provides an important opportunity to expand prevention efforts to reach those most affected and at risk for exploitation. The findings highlight critical areas for augmenting traditional content in school-based HIV/STI and sexuality education classes.

Exploring the Influence of Romantic Relationship Communication on Adolescents' Self-Efficacy to Ask for Sexual Consent.

Adolescence represents a crucial period for sexual and romantic relationship development, and acquisition of skills and confidence essential for effective sexual consent communication. However, various barriers may interfere with adolescents' belief in their ability (i.e., their self-efficacy) to negotiate consent in practice. This study aimed to investigate the state of adolescents' self-efficacy to ask for consent and explore the influence of romantic relationship communication (a construct comprised of three characteristics: relationship assertiveness skills, positive conflict resolution, and communication awkwardness). Participants were 411 adolescents who had current or past relationships (61% girls, 77% Latine, 79% heterosexual). Participants generally reported above-average levels of self-efficacy to ask for consent (M = 4.14 out of 7, SD = 1.24), with LGBQ+ adolescents exhibiting statistically significantly higher levels of self-efficacy compared to heterosexual adolescents (M = 4.51 vs. 4.09, t = -2.66, p = .008). Self-efficacy to ask for consent was positively individually related to positive conflict resolution and relationship assertiveness skills, and negatively related to communication awkwardness (all ps < .001). In a path model, romantic relationship communication displayed a statistically significant association with adolescents' self-efficacy to ask for consent, with high positive conflict resolution, low communication awkwardness, and high relationship assertiveness skills being associated with higher self-efficacy to ask for consent. Findings suggest improving adolescents' romantic communication skills may enhance their self-efficacy to ask for consent, and contribute to increased rates of sexual consent communication. Intervention strategies should target multiple levels of influence to promote positive consent cognitions, behaviors, and cultural norms.

Promoting Healthy Adolescent Romantic Relationships: Results of a Multisite, Two-group Parallel Randomized Clinical Trial.

PURPOSE: To examine the impact of About Us, an innovative healthy relationships intervention that promotes positive adolescent romantic relationships and the use of effective contraceptives, on improving behavior, attitudes, and intentions related to sexual intercourse, relationship communication, and conflict resolution at 3- and 9-month follow-up, compared to services as usual. METHODS: This was a multi-site, two-group, parallel, randomized-controlled trial with an intervention/comparison allocation ratio of 3:2 conducted at seven high schools in California between February 2018 and May 2021. RESULTS: Overall, our study did not find statistically significant evidence of improved behavior, attitudes, and intentions related to sexual intercourse, relationship communication, and conflict resolution among participants (14-18 years old) randomized to the intervention group (n = 316) compared to services as usual (n = 217) during follow-up (group x time; p > .05). Exploratory within group analyses showed that, compared to baseline, at the 3-month follow-up, the prevalence of reporting having had sex increased in the control group relative to intervention group (+19% vs. +9%, p < .01). Our sub-group analyses showed that changes in condom use intentions scores differed across school sites (group x time x school; p < .01); mixed (positive and negative) trends were observed for intervention effect, and schools with positive intervention effect trends tended to have greater program participation. DISCUSSION: About Us did not show statistically significant positive impacts on primary or secondary outcomes as anticipated. Our exploratory findings show evidence of some promising trends of intervention effects at the school-level, suggesting a need for better tailored intervention components and/or delivery to address the unique environmental contexts of participants. Overall, the context of study implementation was negatively affected by the COVID-19 pandemic and challenges related to using a non-classroom delivery intervention approach. Combined, these factors may have contributed to the study null findings. Moreover, it is difficult to know (or determine) the intervention's impact under more ideal conditions (i.e., no COVID pandemic).

A Group Randomized Trial Evaluating High School FLASH, a Comprehensive Sexual Health Curriculum.

PURPOSE: To evaluate the effectiveness of a school-based comprehensive sexual health curriculum (FLASH) on high-school students' sexual behavior and related outcomes. METHODS: A cohort of 1,597 9th and 10th grade students representing 20 schools from two regions in the U.S. (Midwest and South) were enrolled and completed the baseline survey. Following baseline, the 20 schools were randomly assigned to receive FLASH (n = 10 schools, five per region) or a knowledge-based sexual health curriculum (n = 10 schools, five per region). Follow-up surveys were administered at 3 months and 12 months after the instruction period. RESULTS: There were no statistically significant differences between conditions for the overall sample on rates of vaginal sex in the past 3 months or the rates of vaginal sex without a condom or other birth control. In supplementary subgroup analyses of students who were not sexually experienced at baseline, FLASH showed a statistically significant protective impact at the 3-month follow-up on vaginal sex without a condom or birth control (p = .04). FLASH also showed statistically significant gains in psychosocial outcomes, such as refusal and condom use self-efficacy, attitudes toward birth control and condoms, and perceived norms. CONCLUSIONS: FLASH demonstrated consistent short-term and long-term impacts on key behavioral determinants. It also showed a significant impact on vaginal sex without a condom or other birth control for the subgroup of students who were not sexually experienced at baseline. Behavioral impacts were not evident for the entire study population.

Promoting Adolescent Healthy Relationships (The About Us Program): Protocol for a Randomized Clinical Trial.

BACKGROUND: Romantic relationships play a critical role in adolescent development, and by middle adolescence, most young people have been involved in at least one romantic relationship, a context in which most sexual interactions occur. Research suggests adolescents lack positive models and skills related to building healthy relationships. OBJECTIVE: This project aims to test the impact of an innovative healthy relationships intervention, called About Us, implemented in school-based health centers (SBHCs) in California in a randomized controlled trial. METHODS: About Us is being tested using a 7-site, 2-group, parallel randomized controlled trial with a treatment versus control allocation ratio of 3:2 to assess the impact of the intervention relative to the standard of care among adolescents aged 14 to 18 years. Adolescents with active parental consent provide study assent at each of the 3 survey time points: baseline, 3 months postintervention, and 9 months postintervention. A stratified randomization procedure was used to ensure balance in key covariates and screening criteria across intervention groups. Through benchmark intent-to-treat analyses, we will examine the primary outcome of this study-the impact of About Us relative to the standard of care 9 months following the end of the intervention on the prevalence of vaginal or anal sex without condoms in the past 3 months. The secondary outcomes are four-fold: what is the impact of About Us relative to the standard of care 3 and 9 months following the end of the intervention, on (1) the prevalence of abstinence from vaginal or anal sex in the past 3 months, (2) composite scores of relationship communication and positive conflict resolution among participants involved in a relationship at baseline, (3) the prevalence of SBHC service use or information receipt in the past 3 months, and (4) composite scores of condom use intentions and attitudes regarding condoms and other birth control? Additionally, as part of our sensitivity analyses, two additional analyses will be implemented: modified intent-to-treat and complete case analysis. RESULTS: This project (ClinicalTrials.gov #NCT03736876) was funded in 2016 through the Family Youth Services Bureau as part of the Personal Responsibility Education Innovative Strategies program. Baseline data collection took place between February 2018 and March 2020, yielding a total of 5 cohorts and 533 study participants: 316 assigned to treatment and 217 assigned to control. Ongoing follow-up data collection continued through May 2021. CONCLUSIONS: About Us draws on developmental science to create a contextually and developmentally relevant program that addresses motivation and emotional influences in sexual decision-making. The intervention was designed for implementation within SBHCs, an understudied venue for relationship and sexual health promotion interventions. Unfortunately, COVID-19 pandemic restrictions led to school closures, interrupting ongoing programming, and in-person follow-up data collection, which has affected study attrition.

Ann's Story: An Authentic Learning Experience for Online Nursing Students.

Preparing students for a complex and ever-changing health-care environment is a daunting task for nurse educators. One way to accomplish this task is by reducing the gap between what is learned in school and what is practiced upon graduation. Nurse educators are challenged to create online environments that engage students with real-life activities that resemble practice-authentic learning. One authentic learning activity created for an oncology nursing course that resonated with students was Ann's Story. Ann, a nursing professor, was diagnosed with cancer, and her story was used in a course about caring for patients with cancer. Ann's goal of making something good come of her cancer diagnosis was met through student comments reflecting newfound wisdom in sharing thoughts, feelings, and compassion with patients rather than concentrating only on the completion of tasks.

Diffuse correlation spectroscopy and frequency-domain near-infrared spectroscopy for measuring microvascular blood flow in dynamically exercising human muscles.

In the last 20 yr, near-infrared diffuse correlation spectroscopy (DCS) has been developed for providing a noninvasive estimate of microvascular blood flow (BF) as a BF index (BFi) in the human skin, muscle, breast, brain, and other tissue types. In this study, we proposed a new motion correction algorithm for DCS-derived BFi able to remove motion artifacts during cycling exercise. We tested this algorithm on DCS data collected during cycling exercise and demonstrated that DCS can be used to quantify muscle BFi during dynamic high-intensity exercise. In addition, we measured tissue regional oxygen metabolic rate (MRO2i) by combining frequency-domain multidistance near-infrared spectroscopy (FDNIRS) oximetry with DCS flow measures. Recreationally active subjects (n = 12; 31 ± 8 yr, 183 ± 4 cm, 79 ± 10 kg) pedaled at 80-100 revolutions/min until volitional fatigue with a work rate increase of 30 W every 4 min. Exercise intensity was normalized in each subject to the cycling power peak (Wpeak). Both rectus femoris BFi and MRO2i increased from 15% up to 75% Wpeak and then plateaued to the end of the exercise. During the recovery at 30 W cycling power, BFi remained almost constant, whereas MRO2i started to decrease. The BFi/MRO2i plateau was associated with the rising of the lactate concentration, indicating the progressive involvement of the anaerobic metabolism. These findings further highlight the utility of DCS and FDNIRS oximetry as effective, reproducible, and noninvasive techniques to assess muscle BFi and MRO2i in real time during a dynamic exercise such as cycling.NEW & NOTEWORTHY To the best of our knowledge, this study is the first to demonstrate that diffuse correlation spectroscopy in combination with frequency-domain near-infrared spectroscopy can monitor human quadriceps microvascular blood flow and oxygen metabolism with high temporal resolution during a cycling exercise. The optically measured parameters confirm the expected relationship between blood flow, muscle oxidative metabolism, and lactate production during exercise.

Blended Learning for Sexual Health Education: Evidence Base, Promising Practices, and Potential Challenges.

BACKGROUND: Blended learning is a combination of online learning and face-to-face instruction, and is increasingly being used in K-12 settings. A meta-analysis conducted for the Department of Education suggests blended learning is more effective than either group-based or online learning alone, particularly in K-12 settings. METHODS: This paper provides a narrative review of the literature from 2000 to 2017 on blended learning as it applies to sexual health education programs, and discusses outcomes, best practices and potential challenges of blended learning that may be important for practitioners and researchers considering this approach. RESULTS: Blended learning approaches are being used successfully in sexual health education programs, including school-based programs, and have yielded positive behavioral and psychosocial changes. Similar to traditional group-based programs, not all outcomes tested in these programs showed positive impact. Designing blended learning programs can be challenging, but there is a large best-practice literature that can inform practitioners interested in using it. CONCLUSIONS: Blended learning approaches are viable for sexual health education and offer numerous advantages to group-based only programs, such as confidential personalization and an instructional approach that is familiar and engaging for participants.

Health Care Professionals' Clinical Perspectives on Glycemic Control and Satisfaction With a New Blood Glucose Meter With a Color Range Indicator: Online Evaluation in India, Russia, China, and the United States.

BACKGROUND: We previously demonstrated in patients with diabetes that displaying blood glucose results in association with color improved their ability to interpret glucose results. OBJECTIVE: The objective of this study was to investigate the perceptions of health care professionals (HCPs) in specific countries about the value of color on a new glucose meter and to determine if HCP perspectives among countries differ on the value of this approach in clinical practice. METHODS: A total of 180 HCPs, including 105 endocrinologists, 34 primary care physicians, 25 diabetes educators, and 16 pharmacists, were recruited from India (n=50), Russia (n=50), China (n=50), and the United States (n=30). These HCPs experienced the OneTouch Select Plus Simple glucose meter online from their own office computer using interactive demonstrations (webpages, meter simulator, and video clips). After providing demographic and current clinical practice insights, HCPs responded to questions about the utility of the color-enhanced glucose meter. RESULTS: Mean age and years in their current professional role for the 180 HCPs was 41.3 (SD 8.1) and 13.3 (SD 6.8) years for endocrinologists, 41.3 (SD 8.3) and 14.1 (SD 6.8) years for primary care physicians, 37.5 (SD 8.7) and 12.7 (SD 6.8) years for diabetes educators, and 35.9 (SD 5.3) and 9.5 (SD 5.2) years for pharmacists. In all, 88% (44/50) of Russian and 83% (25/30) of American HCPs said their patients find it easy to recognize low, in-range, or high blood glucose results compared to 56% (28/50) of HCPs in China and 42% (21/50) in India. Regardless of country, HCPs had less confidence that their patients act on blood glucose results with 52% (26/50) in Russia, 63% (19/30) in the United States, 60% (30/50) in China, and 40% (20/50) in India responding positively. During the interactive online meter experience, HCPs from all countries responded positively to questions about a meter with color features. After reflecting on the value of this meter, most HCPs strongly agreed or agreed their patients would be more inclined to act on results using a meter with color features (Russia: 92%, 46/50; United States: 70%, 21/30; China: 98%, 49/50; India: 94%, 47/50). They also said that color was particularly useful for patients with lower numeracy or education who may struggle with interpreting results (Russia: 98%, 49/50; United States: 77%, 23/30; China: 100%, 50/50; India: 82%, 41/50). CONCLUSIONS: This multicountry online study provides evidence that HCPs had high overall satisfaction with the OneTouch Select Plus glucose meter, which uses color-coded information to assist patients with interpreting blood glucose results. This may be especially helpful in patient populations with low numeracy or literacy and limited access to health care and direct interaction with HCPs.
