RESUMO

BACKGROUND: The United States envisions a 90% reduction in HIV infections by 2030. However, the COVID-19 pandemic disrupted the HIV continuum and disproportionately affected access to social and health services for people at the highest vulnerability. This study shows how stakeholders in the State of Michigan handled disruptions and their key recommendations. As a case study, this study adds to the literature about preparedness for future pandemics. METHODS: We interviewed 33 statewide Michigan HIV/AIDS Council members-practitioners, researchers, and community representatives, guiding service planning, improvement, and resource allocations, measuring group cohesiveness using a tested scale. We measured group cohesiveness as a proxy for how individual opinions reflected those of the Council as a group. We used qualitative questions to assess: (1) how the COVID-19 pandemic disrupted HIV prevention; (2) how disruptions were handled; and (3) recommendation to help address disruptions now and in the future. Using thematic analysis, we coded the interviews. RESULTS: We found a high degree of cohesiveness. Participants agreed that the pandemic disrupted HIV prevention services (e.g., HIV testing, PrEP education, referrals to primary care, etcetera) offered by community organizations, hospital clinics, and health departments across the state. In response, they developed online and curbside services to maintain HIV services, abate social isolation, and address structural issues like lack of food and public transportation. We organized results in four categories: (1) HIV service disruptions (e.g., "Housing for women and children who are fleeing a legal situation"); (2) Responses to disruptions (e.g., "Some of them, we would say, hey, weather permitting, we'll come out to your car"); (3) Minoritized groups disproportionately affected (e.g., "Especially in my community, to get people if there's ever a vaccine, Black people are going to be the last people to take it"); and (4) Recommendations (below). CONCLUSIONS: The pandemic unsettled and further exacerbated every aspect of HIV service provision. The main recommendation was to overhaul communication systems between government and organizations offering HIV services to mitigate disruptions and improve the chances of achieving a 90% reduction.

RESUMO

BACKGROUND: Adaptive interventions are often used in individualized health care to meet the unique needs of clients. Recently, more researchers have adopted the Sequential Multiple Assignment Randomized Trial (SMART), a type of research design, to build optimal adaptive interventions. SMART requires research participants to be randomized multiple times over time, depending upon their response to earlier interventions. Despite the increasing popularity of SMART designs, conducting a successful SMART study poses unique technological and logistical challenges (e.g., effectively concealing and masking allocation sequence to investigators, involved health care providers, and subjects) in addition to other challenges common to all study designs (e.g., study invitations, eligibility screening, consenting procedures, and data confidentiality protocols). Research Electronic Data Capture (REDCap) is a secure, browser-based web application widely used by researchers for data collection. REDCap offers unique features that support researchers' ability to conduct rigorous SMARTs. This manuscript provides an effective strategy for performing automatic double randomization for SMARTs using REDCap. METHODS: Between January and March 2022, we conducted a SMART using a sample of adult (age 18 and older) New Jersey residents to optimize an adaptive intervention to increase COVID-19 testing uptake. In the current report, we discuss how we used REDCap for our SMART, which required double randomization. Further, we share our REDCap project XML file for future investigators to use when designing and conducting SMARTs. RESULTS: We report on the randomization feature that REDCap offers and describe how the study team automated an additional randomization that was required for our SMART. An application programming interface was used to automate the double randomizations in conjunction with the randomization feature provided by REDCap. CONCLUSIONS: REDCap offers powerful tools to facilitate the implementation of longitudinal data collection and SMARTs. Investigators can make use of this electronic data capturing system to reduce errors and bias in the implementation of their SMARTs by automating double randomization. TRIAL REGISTRATION: The SMART study was prospectively registered at Clinicaltrials.gov; registration number: NCT04757298, date of registration: 17/02/2021.

RESUMO

To mitigate the opioid epidemic, a concerted effort to educate, prevent, diagnose, treat, and engage residents is required. In this study, a digitally distributed method to form a large network of organizations was tested with 99 counties in regions with high vulnerability to hepatitis C virus (HCV). The method involved a cascade of contacts going from email to phone calls, to videoconferencing and measuring the number of contacts required, amount of time taken, and the proportion of success at recruiting at least one community organization per county. A recruitment period of 5 months and 2118 contact attempts led to the recruitment of organizations from 73 out of our 99 target counties. Organizations belonging to health departments required more attempts and time to recruit but ultimately enrolled at higher rates than did other organizations such as coalitions and agencies. Organizations from counties more (vs. less) vulnerable to HCV outbreaks required more attempts to recruit and, using multiple recruitment methods (e.g., emails, phone calls, and Zoom meetings), improved enrollment success. Overall, this method proved to be successful at remotely engaging a large-scale network of communities with different levels of risk within a large geographic region.

RESUMO

BACKGROUND: The study examines the rate of alcohol, tobacco, and marijuana use among White, African American, and Latino adolescents and whether racial/ethnic bullying subtypes (victim-only, bullies-only, and bully/victim) are related to alcohol, tobacco, and marijuana use. METHODS: We used data from the 2009-2010 Health Behaviour in School-aged Children study (n = 9863) to examine differences in alcohol, tobacco, and marijuana use among White, African American, and Latino adolescents in the USA, and assessed whether racial/ethnic bullying involvement was associated with alcohol, tobacco, and marijuana use among these adolescents. Adolescents were categorized into four groups based on whether they had experienced racial bullying perpetration, victimization, both perpetration, and victimization, or neither perpetration nor victimization. Descriptive statistics were conducted to examine the distributions of the study variables and describe the samples. Spearman's rank-order correlation analyses were used to examine the relationships among the variables. Multinomial logistic regression was conducted to examine alcohol, tobacco, and marijuana use among the racial bully victimization, perpetration, and victimization-perpetration groups compared to the non-involved group by race/ethnicity. RESULTS: The White victim-only group was more likely to use alcohol but less likely to use tobacco. The African American victim-only group was more likely to use alcohol, and the bully/victim group was more likely to use marijuana. The Latino victim-only group was more likely to use alcohol, whereas the bully/victim group was more likely to use tobacco. CONCLUSION: Our findings have implications for the development and implementation of prevention and intervention programs across different racial/ethnic adolescent groups.

RESUMO

BACKGROUND AND AIM: Screening adolescents at risk for cannabis use disorders is critical. The CRAFFT is a screening tool designed to address both alcohol and drug use among youth. Current study tests the psychometric properties of the CRAFFT and attempts to modify one of the screening items to compare the efficiency. DESIGN: We examined the ideal cut-off point of the CRAFFT for identifying persons with heavy cannabis use and compared the utility of the original and revised CRAFFT. PARTICIPANTS: Sample (N = 132,555) averaged 16.19 (±1.21) years of age; 51.0% were female, 59.7% were White, 15.2% were Latino/Latina, and 6.7% were African-American. Majority resided in non-rural area and 34.5% were receiving free or reduced lunch at school. MEASUREMENTS: Heavy cannabis use was defined as using cannabis 10 or more times in the past 30 days. Sensitivity, specificity, the area under the receiver operating characteristic curve, and Youden value were analyzed to determine the ideal cut-off point. FINDINGS: Maximum overall predictive accuracy was at a cutoff score of 2 or higher when using the original CRAFFT questions. At a cutoff score of 2, sensitivity was 82.0%, specificity was 83.7%, with an AUC of 0.880. On the contrary, when an alternative CAR question was used, maximum predictive accuracy was at a cutoff score of 1 or higher when predicting heavy cannabis use. At a cutoff score of 1, sensitivity was 92.7%, specificity was 75.5%, with an AUC of 0.900. CONCLUSIONS: The results provide evidence that the CRAFFT is a promising brief diagnostic instrument for heavy cannabis use among youth. Modification to Car item may have potential in reducing disparities in sensitivity among different racial ethnic groups, as well as those who with low socioeconomic status.

RESUMO

PURPOSE: This study explored survivorship services provided at National Cancer Institute (NCI)-Designated Cancer Centers for patients with blood cancer to identify gaps in services, unmet needs, and barriers to access. METHODS: Qualitative interviews with national experts and blood cancer survivors aided the development of an online survey distributed to a survivorship clinic director or staff at 63 NCI-Designated Cancer Centers. RESULTS: Staff at 71% of centers participated (n = 45). Survivorship needs identified as most important-follow-up for health issues due to treatment side effects, healthy behavior programming, and individual mental health services-were reported as offered at 91%, 84%, and 84% of centers, respectively. However, respondents indicated that satellite centers offered these services 20% of the time or less. Forty-five percent reported that they believed the majority of survivorship needs of patients with blood cancer who have completed treatment were not adequately met by their center or other organizations. Most frequently indicated barriers to accessing services were distance from the patient's home and lack of primary care physician adherence to best practices or knowledge of late/long-term effects. CONCLUSIONS: To enhance survivorship services for patients with blood cancer, NCI-Designated Cancer Centers and non-profits should focus on increasing access to services for survivors who do not reside near the main center and improving coordination between oncology, mental health, and primary care. IMPLICATIONS FOR CANCER SURVIVORS: Understanding survivorship service delivery is an important step toward developing solutions that help survivors seek and access support at their site of care and from other non-profit organizations.

RESUMO

PURPOSE: To describe nongenetics clinicians' perceptions and knowledge of cancer genetics and laws prohibiting genetic discrimination, attitudes toward the use of cancer genetic testing, and referral practices. METHODS: Invitations to participate were sent to a random stratified sample of California Medical Association members and to all members of California Association of Nurse Practitioners and California Latino Medical Association. Responders in active practice were eligible and completed a 47-item survey. RESULTS: There were 1181 qualified participants (62% physicians). Although 96% viewed genetic testing as beneficial for their patients, 75% believed fear of genetic discrimination would cause patients to decline testing. More than 60% were not aware of federal or California laws prohibiting health insurance discrimination--concern about genetic discrimination was selected as a reason for nonreferral by 11%. A positive attitude toward genetic testing was the strongest predictor of referral (odds ratio: 3.55 [95% confidence interval: 2.24-5.63], P < 0.001) in stepwise logistic regression analyses. The higher the belief in genetic discrimination, the less likely a participant was to refer (odds ratio: 0.72 [95% confidence interval: 0.518-0.991], P < 0.05), whereas more knowledge of genetic discrimination law was associated with comfort recommending (odds ratio: 1.18 [95% confidence interval: 1.11-1.25], P < 0.001) and actual referral (odds ratio: 3.55 [95% confidence interval: 2.24-5.63], P < 0.001). CONCLUSION: Concerns about genetic discrimination and knowledge deficits may be barriers to cancer genetics referrals. Clinician education may help promote access to cancer screening and prevention.

RESUMO

BACKGROUND: The role of angiotensin II (Ang II) in mediating excessive sodium reabsorption in diabetic nephropathy is recognized. Serine-glucocorticoid kinase-1 (SGK-1) increases sodium-hydrogen exchanger-3 (NHE3) expression and is known to be upregulated in in vitro and in vivo models of diabetic nephropathy. However, a link between Ang II and SGK-1 in diabetic nephropathy has not been established. METHODS: Ang II production in cultured human proximal tubular cells was measured under normal (5 mM) and high (25 mM) glucose conditions. The Ang II type 1 receptor was identified by RT-PCR. SGK-1 and NHE3 mRNA and protein expression was measured in proximal tubule cells (PTCs) exposed to Ang II. EIPA inhibitable changes in cell sodium uptake were undertaken to confirm that alterations in NHE3 mRNA and protein were reflected in transport activity. SGK-1 was silenced in the PTCs using small interfering RNA to determine the role of SGK-1 in mediating Ang II-induced increases in NHE3-mediated sodium uptake. RESULTS: Ang II production by PTCs was significantly increased by exposure to high glucose (P < 0.02). Ang II increased NHE3 and SGK-1 mRNA expression to 275 +/- 30% (P < 0.02) and 130 +/- 10% (P < 0.05) respectively. Silencing of SGK-1 reduced Ang II-stimulated NHE3 protein expression to 49.8 +/- 6.1% (P < 0.05) of control levels. SGK-1 silencing abolished increases in (22)Na(+) uptake seen in Ang II-treated cells to 86.7 +/- 1.6% of control values. CONCLUSION: These data suggest that increased sodium reabsorption in renal proximal tubular cells considered to be due to Ang II in diabetes mellitus is mediated through SGK-1 expression.
