"Just the Stigma Associated with PrEP Makes You Feel Like It's HIV Itself": Exploring PrEP Stigma, Skepticism, and Medical Mistrust Among Black Cisgender Women in Urban and Rural Counties in the U.S. Deep South.

Despite its effectiveness in HIV prevention, PrEP use among Black women is suboptimal. Notably in the Deep South, Black women have the lowest PrEP uptake rates among all US regions. To increase PrEP engagement, research suggests the implementation of structural and social interventions particular to the needs of Black women. The state of Alabama is of priority to federal HIV prevention initiatives; therefore, this study conducted focus groups among 47 cis-gender Black women in rural and urban Alabama counties, with the highest statewide HIV incidence rates, to understand perceptions of PrEP and decision-making processes. Deductive coding analysis was conducted and themes were finalized based on consensus among the two coders. Four themes were identified. Findings show stigma undergirds Alabaman Black women's decisions to engage in PrEP care. Moreover, women reported stigma stifled community-level education about PrEP. Despite these experiences, education was regarded as a strategy to decrease stigma and PrEP skepticism, the latter of which emerged as a prominent theme. Medical mistrust and healthcare engagement were the other emergent themes influencing participation in PrEP care. To ensure PrEP efforts meet the needs of Black cisgender women in Alabama counties, interventions must address longstanding stigma, increase educational initiatives, and ensure interventions consider women's experiences with medical mistrust and health care engagement.

Multilevel Resilience and HIV Virologic Suppression Among African American/Black Adults in the Southeastern United States.

OBJECTIVE: To assess overall and by neighborhood risk environments whether multilevel resilience resources were associated with HIV virologic suppression among African American/Black adults in the Southeastern United States. SETTING AND METHODS: This clinical cohort sub-study included 436 African American/Black participants enrolled in two parent HIV clinical cohorts. Resilience was assessed using the Multilevel Resilience Resource Measure (MRM) for African American/Black adults living with HIV, where endorsement of a MRM statement indicated agreement that a resilience resource helped a participant continue HIV care despite challenges or was present in a participant's neighborhood. Modified Poisson regression models estimated adjusted prevalence ratios (aPRs) for virologic suppression as a function of categorical MRM scores, controlling for demographic, clinical, and behavioral characteristics at or prior to sub-study enrollment. We assessed for effect measure modification (EMM) by neighborhood risk environments. RESULTS: Compared to participants with lesser endorsement of multilevel resilience resources, aPRs for virologic suppression among those with greater or moderate endorsement were 1.03 (95% confidence interval: 0.96-1.11) and 1.03 (0.96-1.11), respectively. Regarding multilevel resilience resource endorsement, there was no strong evidence for EMM by levels of neighborhood risk environments. CONCLUSIONS: Modest positive associations between higher multilevel resilience resource endorsement and virologic suppression were at times most compatible with the data. However, null findings were also compatible. There was no strong evidence for EMM concerning multilevel resilience resource endorsement, which could have been due to random error. Prospective studies assessing EMM by levels of the neighborhood risk environment with larger sample sizes are needed.

Delivery of the HIV Service and Telemedicine Through Effective Patient-Reported Outcomes (+STEP) Intervention to Increase Screening and Treatment of Mental Health and Substance Use Disorders for People Living With HIV in Alabama: Protocol for an Effectiveness-Implementation Study.

BACKGROUND: The syndemic of mental health (MH) and substance use disorders (SUDs) is common among persons living with HIV and jeopardizes HIV treatment adherence, engagement in care, and viral load suppression. Electronic patient-reported outcomes (ePROs), completed through tablet or computer, and telemedicine are evidence- and technology-based interventions that have been used to successfully increase screening and treatment, respectively, a model that holds promise for persons living with HIV. To date, there is limited guidance on implementing ePROs and telemedicine into HIV clinical practice even though it is well known that these evidence-based tools improve diagnosis and access to care. OBJECTIVE: To address this, we aim to conduct a multicomponent intervention for persons living with HIV, including the delivery of HIV services and telemedicine through effective ePROs (+STEP), to increase screening and treatment of MH and SUD in Ryan White HIV/AIDS Program (RWHAP)-funded clinics in Alabama. METHODS: Through this intervention, we will conduct a readiness, acceptability, and accessibility assessment and implement +STEP to improve the diagnosis and treatment of MH and SUD at RWHAP clinics in Alabama. To describe implementation strategies that address barriers to the uptake of +STEP in RWHAP clinics, we will conduct qualitative interviews in years 1 (early implementation), 2 (scale up), and 4 (maintenance) with patients and key staff to evaluate barriers, facilitators, and implementation strategies. Our Results will enable us to modify strategies to enhance +STEP penetration over time and inform the implementation blueprint, which we will develop for both RWHAP clinics in Alabama and future sites. We will assess the impact of implementing +STEP on diagnoses, referrals, and health care use related to MH, SUD, and HIV by comparing clinical outcomes from patients receiving these interventions (ePROs and telemedicine) with historical controls. RESULTS: The first study site began implementation in April 2022. A total of 2 additional sites have initiated ePROs. Final results are expected in 2026. The results of this study will provide a foundation for future research expanding access to ePROs for improved diagnosis linked to telemedicine access to accelerate patients along the continuum of care from MH and SUD diagnosis to treatment. CONCLUSIONS: Achieving the end of the HIV epidemic in the United States necessitates programs that accelerate movement across the MH and SUD care continuum from diagnosis to treatment for persons living with HIV. Scaling these services represents a path toward improved treatment outcomes with both individual health and population-level prevention benefits of sustained HIV viral suppression in the era of undetectable=untransmittable (U=U). This study will address this evidence gap through the evaluation of the implementation of +STEP to establish the necessary systems and processes to screen, identify, and better treat substance use and MH for people living with HIV.

Factors Associated With Willingness to Use Preexposure Prophylaxis Among Black Cisgender Women Residing in Rural and Urban Areas: A Cross-Sectional Study.

BACKGROUND: Black cisgender women (CGW) are disproportionately impacted by the human immunodeficiency virus (HIV) epidemic in the United States. Black women account for 57% of the total new diagnoses among CGW. In addition, Black CGW women are 9 times more likely to be diagnosed with HIV than their White counterparts. METHODS: We conducted surveys (September 2019-March 2020) and collected information on sociodemographics, HIV/preexposure prophylaxis (PrEP) knowledge, HIV/PrEP stigma, sexual practices, and other factors identified as PrEP barriers among Black CGW (n = 795). This cross-sectional study used logistic regression models to assess intrapersonal, interpersonal, and structural factors among individuals willing to use PrEP versus individuals unwilling or unsure to use PrEP. RESULTS: Our study population had a mean age of 37 years, predominantly lived in urban areas (65%), had stable housing (96.7%), and had private insurance/Medicare (78.2%). Overall, 29.6% reported willingness to use PrEP, 35.6% reported unwillingness to use PrEP, and 34.8% were unsure of PrEP use. The multivariable analysis showed that, compared with individuals reporting unwillingness/unsure to PrEP use, those reporting willingness to PrEP use were younger (adjusted odds ratio [AOR; 95% confidence interval {CI}], 0.97 [0.96-0.99]), had lower odds of intimate partner violence (AOR [95% CI], 0.87 [0.78-0.98), and had higher odds of organizational religiosity (AOR [95% CI], 1.10 [1.01-1.20]), HIV knowledge (AOR [95% CI], 1.08 [1.03-1.13]), and perceived need for PrEP (AOR [95% CI], 6.38 [3.36-12.11]). CONCLUSIONS: Preexposure prophylaxis willingness among Black CGW was impacted by individual-level, interpersonal, and structural factors. Improving PrEP willingness and uptake among Black CGW will require multilevel interventions.

Strategic Surge Responses in the COVID-19 era: Operational Themes, Innovative Solutions and Lessons Learned by Three Freestanding Pediatric Emergency Departments.

The prolonged COVID-19 pandemic has created unique and complex challenges in operational and capacity planning for pediatric emergency departments, as initial low pediatric patient volumes gave way to unpredictable patient surges during Delta and Omicron variants. Compounded by widespread hospital supply chain issues, staffing shortages due to infection and attrition, and a concurrent pediatric mental health crisis, the surges have pushed pediatric emergency department leaders to re-examine traditionally defined clinical processes, and adopt innovative operational strategies. This study describes the strategic surge response and lessons learned by 3 major freestanding academic pediatric emergency departments in the western United States to help inform current and future pediatric pandemic preparedness.

Improvements to the Gulf pipefish Syngnathus scovelli genome.

The Gulf pipefish Syngnathus scovelli has emerged as an important species for studying sexual selection, development, and physiology. Comparative evolutionary genomics research involving fishes from Syngnathidae depends on having a high-quality genome assembly and annotation. However, the first S. scovelli genome assembled using short-read sequences and a smaller RNA-sequence dataset has limited contiguity and a relatively poor annotation. Here, using PacBio long-read high-fidelity sequences and a proximity ligation library, we generate an improved assembly to obtain 22 chromosome-level scaffolds. Compared to the first assembly, the gaps in the improved assembly are smaller, the N75 is larger, and our genome is ~95% BUSCO complete. Using a large body of RNA-Seq reads from different tissue types and NCBI's Eukaryotic Annotation Pipeline, we discovered 28,162 genes, of which 8,061 are non-coding genes. Our new genome assembly and annotation are tagged as a RefSeq genome by NCBI and provide enhanced resources for research work involving S. scovelli..

Evaluation of the efficacy and mechanisms of a novel intervention for chronic pain tailored to people with HIV: The STOMP protocol.

BACKGROUND: Behavioral interventions for chronic pain among people with HIV (PWH) are understudied, with great potential to improve pain and function. Chronic pain is an important comorbidity that affects between 30% and 85% of PWH and is associated with greater odds of functional impairment, increased emergency room utilization, suboptimal retention in HIV care, and failure to achieve virologic suppression. However, to date, there are few effective and scalable interventions for chronic pain in PWH. OBJECTIVE: This manuscript outlines the protocol for a randomized control trial of a novel theory-based pain self-management intervention, "Skills TO Manage Pain" (STOMP), developed for and tailored to PWH versus enhanced usual care controls. STOMP is a 12-week intervention developed from prior work on pain self-management in PWH and rigorous intervention mapping. The STOMP intervention has three major components: group sessions, one-on-one pain self-management sessions, and peer leaders. METHODS: STOMP is a 2-arm randomized trial conducted with PWH with chronic pain. The trial compares STOMP, a theory-based intervention tailored to improving chronic pain in PWH, with a comparison group receiving enhanced usual care effectiveness on pain and HIV proximal outcome measures. The proposed sample size is 280 PWH recruited from two high-volume Center for AIDS Research Network of Integrated Clinical Systems clinical sites. RESULTS: Study procedures are ongoing, and results will be recorded in future manuscripts. CONCLUSION: The study will generate evidence on the effectiveness of STOMP with the potential to dramatically change chronic pain treatment for PWH.

The evolution of the testis transcriptome in pregnant male pipefishes and seahorses.

In many animals, sperm competition and sexual conflict are thought to drive the rapid evolution of male-specific genes, especially those expressed in the testes. A potential exception occurs in the male pregnant pipefishes, where females transfer eggs to the males, eliminating testes from participating in these processes. Here, we show that testis-related genes differ dramatically in their rates of molecular evolution and expression patterns in pipefishes and seahorses (Syngnathidae) compared to other fish. Genes involved in testis or sperm function within syngnathids experience weaker selection in comparison to their orthologs in spawning and livebearing fishes. An assessment of gene turnover and expression in the testis transcriptome suggests that syngnathids have lost (or significantly reduced expression of) important classes of genes from their testis transcriptomes compared to other fish. Our results indicate that more than 50 million years of male pregnancy have removed syngnathid testes from the molecular arms race that drives the rapid evolution of male reproductive genes in other taxa.

PrEP service delivery preferences of black Cis-gender women living in the Southern United States.

To assess PrEP service delivery preferences among Black cis-gender women living in urban and rural settings in Alabama, we conducted a cross-sectional discrete choice experiment survey. Discrete choice experiments included five attributes. Hierarchical Bayes (HB) modeling and latent class analyses (LCA) were used to evaluate attribute preferences. Among 795 Black cis-gender HIV-negative women, almost two-thirds lived in urban settings and reported having at least some college; about a third reported a household income less than $25,000 annually; and reported willingness to use PrEP. Respondents placed the greatest importance on PrEP medication formulation and healthcare facility. LCA showed the group with the highest rural proportion preferred for on-line visits. Black women in the Deep South had distinct preferences regarding PrEP service delivery. These findings can inform tailored interventions to improve PrEP uptake among Black cis-gender women across diverse settings in the South.

Development of Long and Short Forms of the Multilevel Resilience Resource Measure for African American/Black Adults Living with HIV.

Understanding resilience in relation to HIV-related outcomes may help address racial/ethnic disparities, however, significant gaps in its measurement preclude in-depth study. Thus, this research aims to develop and evaluate the psychometric properties of long and short forms of the Multilevel Resilience Resource Measure for African American/Black Adults Living with HIV. To develop the items, we conducted a mixed methods study (N = 48) and reviewed published resilience measures. We completed content validity index analyses to ensure the items reflected the resilience construct. Next, we conducted 20 cognitive interviews and a field survey (N = 400). The long and short forms demonstrated acceptable to excellent psychometric properties based on factorial validity, internal consistency and convergent validity and on measurement invariance (conducted for the short form only). These measures provide a comprehensive framework to examine resilience and HIV-related outcomes and can inform resilience-building interventions to reduce racial and ethnic health disparities.

Phase I Trial of DNA Methyltransferase Inhibitor Guadecitabine Combined with Cisplatin and Gemcitabine for Solid Malignancies Including Urothelial Carcinoma (SPIRE).

PURPOSE: Preclinical data indicate that DNA methyltransferase inhibition will circumvent cisplatin resistance in various cancers. PATIENT AND METHODS: SPIRE comprised a dose-escalation phase for incurable metastatic solid cancers, followed by a randomized dose expansion phase for neoadjuvant treatment of T2-4a N0 M0 bladder urothelial carcinoma. The primary objective was a recommended phase II dose (RP2D) for guadecitabine combined with gemcitabine and cisplatin. Treatment comprised 21-day gemcitabine and cisplatin cycles (cisplatin 70 mg/m2, i.v., day 8 and gemcitabine 1,000 mg/m2, i.v., days 8 + 15). Guadecitabine was injected subcutaneously on days 1-5, within escalation phase cohorts, and to half of 20 patients in the expansion phase. Registration ID: ISRCTN 16332228. RESULTS: Within the escalation phase, dose-limiting toxicities related predominantly to myelosuppression requiring G-CSF prophylaxis from cohort 2 (guadecitabine 20 mg/m2, days 1-5). The most common grade ≥3 adverse events in 17 patients in the dose-escalation phase were neutropenia (76.5%), thrombocytopenia (64.7%), leukopenia (29.4%), and anemia (29.4%). Addition of guadecitabine to gemcitabine and cisplatin in the expansion phase resulted in similar rates of severe hematologic adverse events, similar cisplatin dose intensity, but modestly reduced gemcitabine dose intensity. Radical treatment options after chemotherapy were not compromised. Pharmacodynamics evaluations indicated guadecitabine maximal target effect at the point of cisplatin administration. Pharmacokinetics were consistent with prior data. No treatment-related deaths occurred. CONCLUSIONS: The guadecitabine RP2D was 20 mg/m2, days 1-5, in combination with gemcitabine and cisplatin and required GCSF prophylaxis. Gene promoter methylation pharmacodynamics are optimal with this schedule. Addition of guadecitabine to gemcitabine and cisplatin was tolerable, despite some additional myelosuppression, and warrants further investigation to assess efficacy.

A Concept Mapping Study to Understand Multilevel Resilience Resources Among African American/Black Adults Living with HIV in the Southern United States.

Resilience may help people living with HIV (PLWH) overcome adversities to disease management. This study identifies multilevel resilience resources among African American/Black (AA/B) PLWH and examines whether resilience resources differ by demographics and neighborhood risk environments. We recruited participants and conducted concept mapping at two clinics in the southeastern United States. Concept Mapping incorporates qualitative and quantitative methods to represent participant-generated concepts via two-dimensional maps. Eligible participants had to attend ≥ 75% of their scheduled clinic appointments and did not have ≥ 2 consecutive detectable HIV-1 viral load measurements in the past 2 years. Of the 85 AA/B PLWH who were invited, forty-eight participated. Twelve resilience resource clusters emerged-five individual, two interpersonal, two organizational/policy and three neighborhood level clusters. There were strong correlations in cluster ratings for demographic and neighborhood risk environment comparison groups (r ≥ 0.89). These findings could inform development of theories, measures and interventions for AA/B PLWH.

Barriers and facilitators for screening and treatment of hyperlipidemia among patients with inflammatory arthritis.

BACKGROUND: Patients with inflammatory arthritis (IA), defined as rheumatoid arthritis (RA) and psoriatic arthritis (PsA), are at increased risk for cardiovascular disease (CVD). The frequency of screening and treatment of hyperlipidemia, a modifiable CVD risk factor, is low in these patients. The reasons for low screening and treatment rates in this population are poorly understood. Our objective was to elicit the barriers and facilitators for screening and treatment of hyperlipidemia from the perspective of patients with IA. METHODS: We conducted a qualitative study using focus groups of patients with IA, guided by Bandura's Social Cognitive Theory. We recruited patients with IA aged 40 years and older from a single academic center. Data were analyzed thematically. RESULTS: We conducted three focus groups with 17 participants whose mean age was 56 (range 45-81) years; 15 were women. Four themes emerged as barriers: 1) need for more information about arthritis, prognosis, and IA medications prior to discussing additional topics like CVD risk; 2) lack of knowledge about how IA increases CVD risk; 3) lifestyle changes to reduce overall CVD risk rather than medications; and 4) the need to improve doctor-patient communication about IA, medications, and CVD risk. One theme emerged as a facilitator: 5) potential for peer coaches (patients with IA who are trained about concepts of CVD risk and IA) to help overcome barriers to screening and treatment of hyperlipidemia to lower CVD risk. CONCLUSION: Patients with IA identified educational needs about IA, increased CVD risk in IA and the need for improved doctor-patient communication about screening for hyperlipidemia and its treatment. Patients were receptive to working with peer coaches to facilitate achievement of these goals.

Rates and Patterns of Lower Extremity Sports Injuries in All Gender-Comparable US High School Sports.

BACKGROUND: High school athletes with lower extremity sports injuries (LESIs) frequently present to the emergency department in the United States. Previous epidemiological studies have presented rates and mechanisms of LESIs in these athletes. No studies, however, have looked at LESIs in gender-comparable sports in an attempt to evaluate what differences exist between LESIs in boys and girls. PURPOSE: To describe the epidemiology of LESIs among US high school athletes using a large national database of athletes in sports that could be considered gender comparable, given the rules of play and protective equipment. STUDY DESIGN: Descriptive epidemiology study. METHODS: Descriptive data from 2005 to 2016 were collected using the internet-based High School Reporting Information Online (High School RIO), a national high school sports injury surveillance system, for athletes participating in 8 gender-comparable sports (soccer, volleyball, basketball, baseball/softball, swimming and diving, track and field, cross-country, and tennis). Rates and patterns of injury were evaluated, with injury rates calculated as ratio of injuries per 10,000 athlete-exposures. Rate ratios (RRs) were calculated to compare the LESI rates in girls and boys. RESULTS: In both genders, LESI rates (per 10,000 athlete-exposures) were highest in soccer (girls, 15.87; boys, 11.68) followed by basketball (girls, 11.51; boys, 9.35), and were lowest in swimming and diving (girls, 0.70; boys, 0.39). Although injury rates were significantly higher in girls compared with boys in all sports, only in tennis was the RR greater than 2 (RR, 2.03; 95% CI, 1.17-3.54). Girls had a greater proportion of severe LESIs and injuries that received radiographic evaluation, such as magnetic resonance imaging, compared with boys for all sports except volleyball. Consistency in the mechanism of injury was demonstrated between genders within each sport. CONCLUSION: This study demonstrated that LESIs are common among high school athletes and disproportionately affect girls more than boys, especially when looking at severe injuries and resource utilization. Further studies are needed to elucidate the cause of these findings. We hope that the awareness of gender-based differences in LESIs will lead to improvements in targeted efforts to decrease injury rates and injury severity.

Which patient reported outcome domains are important to the rheumatologists while assessing patients with rheumatoid arthritis?

BACKGROUND: Patient-reported outcomes (PROs) aid in rheumatoid arthritis (RA) management, but it is not well understood which measures would be most relevant to the rheumatologists for making treatment decisions. METHODS: We recruited rheumatologists nationally to participate in moderated structured group teleconference discussions using the nominal group technique. Participants in each group generated lists of the elements from patient's history and signs that they use to make treatment recommendations for RA. Each participant then selected the three most important elements from the generated list. The results of each group were then combined and summarized. RESULTS: Twenty-five rheumatologists participated in 4 groups (group size ranged from 4 to 8) and 150 available ranking votes across all groups. The statements generated across the 4 groups were categorized into 13 topics (including symptoms, physical function, comorbidities, social aspects, physical findings, response to treatment, treatment adherence, pain management, side effects, tests, access to care, contraception, and organ involvement), 10 of which received ranking votes. Symptoms received the highest ranking (46% of votes), followed by physical function (16%), and physical findings (13%). Among the unranked topics, social aspects had the highest number of statements (8 statements). CONCLUSION: Rheumatologists highly valued patient-reported RA symptoms and physical function to inform their treatment decisions, even above objective data such as physical findings and test results. These results can guide the selection of validated PRO measures to assess these domains to inform the clinical care of patients with rheumatoid arthritis.

Perspectives of Rheumatoid Arthritis Patients on Electronic Communication and Patient-Reported Outcome Data Collection: A Qualitative Study.

OBJECTIVE: To identify the perspectives of patients with rheumatoid arthritis (RA) on electronic recording of between-visit disease activity and other patient-reported outcomes (PROs) and on sharing this information with health care providers or peers. METHODS: Patients with RA were recruited to participate in focus groups from December 2014 to April 2015. The topic guide and analysis were based on the Andersen-Newman framework. Sessions were audiorecorded, transcribed, independently coded, and analyzed for themes. RESULTS: Thirty-one patients participated in 7 focus groups. Their mean ± SD age was 51 ± 13.1 years, 94% were women, 52% were African American, 11% were Hispanic, and 37% were white. Three themes emerged: provider communication, information-seeking about RA, and social and peer support. Participants expressed a willingness to track disease activity data to share with health care providers electronically if providers would act on the information. Participants envisioned symptom tracking and information sharing as a mechanism to relay and obtain reliable information about RA. Participants were also interested in electronic communication between visits if it facilitated learning about symptom management and enhanced opportunities for social support among patients with RA. CONCLUSION: Patients with RA may be amenable to electronic collection and sharing of PRO-type data between clinical encounters if it facilitates communication with health care providers and provides access to reliable information about RA. Providing patients with social support was important for enhancing PROs collection by helping them overcome barriers by using electronic devices and overcome reservations about the value of these data.

Bone lesion absorbed dose profiles in patients with metastatic prostate cancer treated with molecular radiotherapy.

OBJECTIVE: The aim of this study was to calculate the range of absorbed doses that could potentially be delivered by a variety of radiopharmaceuticals and typical fixed administered activities used for bone pain palliation in a cohort of patients with metastatic castration-resistant prostate cancer (mCRPC). The methodology for the extrapolation of the biodistribution, pharmacokinetics and absorbed doses from a given to an alternative radiopharmaceutical is presented. METHODS: Sequential single photon emission CT images from 22 patients treated with 5 GBq of 186Re-HEDP were used to extrapolate the time-activity curves for various radiopharmaceuticals. Cumulated activity distributions for the delivered and extrapolated treatment plans were converted into absorbed dose distributions using the convolution dosimetry method. The lesion absorbed doses obtained for the different treatments were compared using the patient population distributions and cumulative dose-volume histograms. RESULTS: The median lesion absorbed doses across the patient cohort ranged from 2.7 Gy (range: 0.6-11.8 Gy) for 1100 MBq of 166Ho-DOTMP to 21.8 Gy (range: 4.5-117.6 Gy) for 150 MBq of 89Sr-dichloride. 32P-Na3PO4, 153Sm-EDTMP, 166Ho-DOTMP, 177Lu-EDTMP and 188Re-HEDP would have delivered 41, 32, 85, 20 and 64% lower absorbed doses, for the typical administered activities as compared to 186Re-HEDP, respectively, whilst 89Sr-dichloride would have delivered 25% higher absorbed doses. CONCLUSION: For the patient cohort studied, a wide range of absorbed doses would have been delivered for typical administration protocols in mCRPC. The methodology presented has potential use for emerging theragnostic agents. Advances in knowledge: The same patient cohort can receive a range of lesion absorbed doses from typical molecular radiotherapy treatments for patients with metastatic prostate cancer, highlighting the need to establish absorbed dose response relationships and to treat patients according to absorbed dose instead of using fixed administered activities.

Hand and Wrist Injuries Among US High School Athletes: 2005/06-2015/16.

BACKGROUND: The risk of hand/wrist injuries is present across various sports. Little is known about the epidemiology of such injuries. The objective of this study was to calculate the rates of hand/wrist injuries and investigate injury patterns among high school athletes. METHODS: Athlete exposure (AE) and hand/wrist injury data were collected during 11 academic years, 2005/06 through 2015/16, from a large sample of US high schools as part of the National High School Sports-Related Injury Surveillance Study. RESULTS: There were 6723 hand/wrist injuries sustained during 40 195 806 AEs, a rate of 1.7 per 10 000 AEs. The rate of injury in competition (3.3) was higher than in practice (1.1) (95% confidence interval: 2.8-3.1). Rates of hand/wrist injuries varied by sport, with the highest rates in football (4.3), boys' lacrosse (1.9), girls' softball (1.9), wrestling (1.8), girls' field hockey (1.7), boys' ice hockey (1.7), and girls' basketball (1.7). The most common injuries were fracture (45.0%), contusion (11.6%), and ligament sprain (9.0%). Athletes most frequently returned to play in <7 days (45.7%), but 12.4% of injuries kept athletes out ≥3 weeks. CONCLUSIONS: High school athletes are at risk for hand/wrist injuries. Such injuries can keep athletes out of play and many require substantial medical treatment. Stick and ball or puck sports and full contact sports have high rates of hand/wrist injuries relative to other sports, which is indicative of a need for sport-specific prevention efforts.

Neutrophil to Lymphocyte Ratio in Castration-Resistant Prostate Cancer Patients Treated With Daily Oral Corticosteroids.

BACKGROUND: The neutrophil to lymphocyte ratio (NLR) has been shown to be highly prognostic across many tumor types, and predictive of treatment outcome in advanced prostate cancer, and has been postulated to be an indirect measure of tumor inflammation. We evaluated the effect of low-dose steroids on NLR in men suffering from castration-resistant prostate cancer (CRPC). PATIENTS AND METHODS: The NLR was evaluated in a prospective randomized phase II trial that compared prednisolone 5 mg twice daily and dexamethasone 0.5 mg daily administered to 75 chemotherapy and abiraterone/enzalutamide-naive CRPC patients. NLR was examined at baseline (BL), after 6 and 12 weeks of corticosteroid treatment; associations with >50% prostate-specific antigen (PSA) response, duration of response (PSA progression-free interval), and overall survival (OS) were tested using logistic regression and Cox regression analysis. RESULTS: The median NLR for all evaluable patients was 2.6 at BL; 2.9 at 6 weeks; and 4.0 at 12 weeks. After low-dose corticosteroid initiation, 46 patients had a decline in PSA with 24 confirmed responders. BL NLR (log10) associated with a PSA response (odds ratio, .029, 95% confidence interval [CI], .002-.493; P = .014), and with the extent of the PSA decline (P = .009). A favorable BL NLR (less than median) associated with a 5.5-fold higher odds of a PSA >50% response (95% CI, 1.3-23.9; P = .02). Higher BL NLR (log10) associated with a shorter time to PSA progression (hazard ratio [HR], 9.5; 95% CI, 2.3-39.9; P = .002). In multivariate analysis BL NLR as a discrete variable was independently associated with PSA progression (HR, 3.5; 95% CI, 1.5-8.1; P = .003). NLR at 6 weeks was also associated with duration of benefit; in the favorable NLR category time to PSA progression was 10.8 months, for those who converted to an unfavorable (greater than median) category 4.5 months, and for those remaining in a unfavorable category only 1.5 months (95% CI, 0.5-2.5; P = .003). OS was 33.1 months (95% CI, 24.2-42.0) and 21.9 months (95% CI, 19.3-24.4) for those with an favorable and unfavorable BL NLR, respectively. CONCLUSION: Treatment-naive CRPC patients with a high BL or during-treatment NLR appear not to benefit from low-dose corticosteroids. The immunological implications of an unfavorable NLR, and whether corticosteroids might drive prostate cancer progression in patients harboring a high NLR, warrant further study.
