    Abstract Opuntia cespitosa (Cactaceae, previously known under the synonym O. humifusa) is found over eastern North America, yet its populations are very sparse and small despite effective vegetative reproduction. Their edaphic preferences are poorly known, and may limit the distribution and success of the species. Soils were sampled for %O.M. (organic matter), %sand, %silt, %clay, pH, and kg/ha of P, K, Ca, Mg, and Zn in 33 populations over a wide area of eastern North America. Tissue testing was carried out in three populations. Opuntia cespitosa occurs over a wide variety of nutrient conditions and soil textures, including both acidic and alkaline soils, though soil nutrients were generally poor and thin. Populations of the species occurred on soils with very high levels of calcium that could be toxic for other plants, exceeding 20,000 kg/ha in some areas. Plants in these areas also had high Ca tissue levels, also common in desert cacti. Kruskal-Wallis and Spearman′s correlation results suggest that population size was not related to the soil attributes tested, but does indicate that areas mowed by large mowers have larger populations. This may be the result of local vegetative spread of fragments by mowers.

    Abstract Introduction: Hispanic/Latino men who have sex with men (MSM) and transgender women (TGW) are disproportionately affected by HIV in the U.S. This study evaluated HIV prevention services and outcomes among Hispanic/Latino MSM and TGW in the Targeted Highly Effective Interventions to Reduce the HIV Epidemic (THRIVE) demonstration project and consider lessons learned.
    Methods: The authors described the THRIVE demonstration project services provided to Hispanic/Latino MSM and TGW in 7 U.S. jurisdictions from 2015 to 2020. HIV prevention service outcomes were compared between 1 site with (2,147 total participants) and 6 sites without (1,129 total participants) Hispanic/Latino-oriented pre-exposure prophylaxis clinical services, and Poisson regression was used to estimate the adjusted RR between sites and pre-exposure prophylaxis outcomes. Analyses were conducted from 2021 to 2022.
    Results: The THRIVE demonstration project served 2,898 and 378 Hispanic/Latino MSM and TGW, respectively, with 2,519 MSM (87%) and 320 TGW (85%) receiving ≥1 HIV screening test. Among 2,002 MSM and 178 TGW eligible for pre-exposure prophylaxis, 1,011 (50%) MSM and 98 (55%) TGW received pre-exposure prophylaxis prescriptions, respectively. MSM and TGW were each 2.0 times more likely to be linked to pre-exposure prophylaxis (95% CI=1.4, 2.9 and 95% CI=1.2, 3.6, respectively) and 1.6 and 2.1 times more likely to be prescribed pre-exposure prophylaxis (95% CI=1.1, 2.2 and 95% CI=1.1, 4.1), respectively, at the site providing Hispanic/Latino-oriented pre-exposure prophylaxis clinical services than at other sites and adjusted for age group.
    Conclusions: The THRIVE demonstration project delivered comprehensive HIV prevention services to Hispanic/Latino MSM and TGW. Hispanic/Latino-oriented clinical settings may improve HIV prevention service delivery to persons in Hispanic/Latino communities.

    Abstract Purpose: On March 4, 2022, the US Food and Drug Administration (FDA) approved nivolumab plus platinum-doublet chemotherapy for the neoadjuvant treatment of patients with resectable non-small-cell lung cancer (NSCLC). We discuss the FDA's review of the key data and regulatory considerations supporting this approval.
    Patients and methods: The approval was based on the results of CheckMate 816, an international, multiregional, active-controlled trial that randomly assigned 358 patients with resectable NSCLC, stage IB (≥4 cm) to IIIA (N2) per the American Joint Committee on Cancer seventh staging edition to receive either nivolumab plus platinum-doublet or platinum-doublet chemotherapy alone for three cycles before planned surgical resection. The major efficacy end point that supported this approval was event-free survival (EFS).
    Results: At the first planned interim analysis (IA), the hazard ratio (HR) for EFS was 0.63 (95% CI, 0.45 to 0.87;
    Conclusion: This approval, the first for any regimen for the neoadjuvant treatment of NSCLC in the United States, was supported by a statistically significant and clinically meaningful improvement in EFS with no evidence of detriment in OS or negative impact on patients' receipt and timing of surgery or surgical outcomes.

    Abstract Background: Sickle cell trait (SCT) has been associated with an increased risk of sudden death in athletes during strenuous exercise. In August 2010, the National Collegiate Athletic Association (NCAA) began requiring athletes to be screened for SCT, provide proof of SCT status, or sign a waiver and launched an educational campaign for athletes, coaches, and medical staff. The impact of this program is unknown. The purpose of this study was to determine the incidence of death associated with sickle cell trait (daSCT) in NCAA athletes before and after legislation.
    Hypothesis: NCAA SCT legislation will decrease the incidence of daSCT.
    Study design: Observational study.
    Level of evidence: Level 2.
    Methods: A database of NCAA athlete deaths from 2000 to 2019 was reviewed for daSCT. A total of 8,309,050 athlete-years (AY) were included. Incidence of death was calculated before and after legislation.
    Results: The incidence of daSCT in Division I (DI) football athletes before legislation (n = 9) was 1:28,145 AY and after legislation (n = 1) was 1:250,468 AY (relative risk [RR], 0.112; 95% CI, 0.003-0.811;
    Conclusion: The incidence of daSCT in DI football athletes has decreased significantly since legislation was enacted. Cases of daSCT outside of football are rare. It is unclear whether the decrease is related to screening for SCT, education, or both.
    Clinical relevance: This is the first evidence that NCAA SCT legislation may save lives.

    Abstract Background: Electrocardiogram (ECG) screening in athletes enhances the detection of conditions associated with sudden cardiac death (SCD), but concerns remain for false positive results when conducted outside of specialized centers. This study compared ECG interpretation in college athletes between local physicians and a sports cardiology center (SCC).
    Methods: Screening ECGs in athletes from eight Pacific-12 Conference institutions performed between 2010 and 2016 were included. Local interpretation was compared to SCC interpretation using both the Seattle Criteria (SCC-SC) and the International Criteria (SCC-IC).
    Results: A total of 2445 athlete ECGs (mean age 18.5 years; 57.1% male; 63.2% Caucasian and 15.3% African American) were reviewed. The proportion of ECGs classified as abnormal was similar between local and SCC-SC interpretation (3.5% vs. 3.4%, respectively; p = .94), but was lower by SCC-IC interpretation (1.5%, p < .001). ECG abnormalities interpreted as normal by local physicians but as abnormal by SCC-SC (n = 33) and SCC-IC (n = 16) standards included: pathological Q waves (n = 15 SCC-SC; n = 3 SCC-IC), T-wave inversions (n = 8 both), and ST-depressions (n = 3 both). There was a 97.5% ECG interpretation agreement and substantial interobserver reliability (k = 0.611, p < .001) between local and SCC-SC interpretation in athletes screened starting one year after publication of the Seattle Criteria (n = 1388). Both local and SCC physicians correctly identified six abnormal ECGs associated with conditions at risk of SCD.
    Conclusions: ECG interpretation by local physicians at college universities had similar accuracy compared to a specialized SCC with a low overall abnormal rate, similar sensitivity, and substantial interobserver reliability. Uniform application of current ECG interpretation standards is recommended to further improve accuracy.

    Abstract PHEX gene and hypophosphatemia. X-linked hypophosphatemia (XLH) and tumor-induced osteomalacia (TIO) are diseases that have in common abnormal proximal renal tubular function resulting in increased renal clearance of inorganic phosphorus and hypophosphatemia. The recent discovery of the PHEX gene has provided new insights to these disorders. In this regard, identification of the PHEX gene product as a membrane-bound endopeptidase suggests that the pathophysiologic cascade underlying XLH likely involves inactivation mutations of the gene causing a failure to clear an active hormone, phosphatonin, from the circulation. The presence of this hormone through unknown mechanisms decreases the sodium-dependent phosphate cotransporter in the kidney, resulting in impaired phosphate transport. In contrast, TIO likely evolves secondary to tumor overproduction of the putative phosphatonin, which exerts physiologic function despite efforts to counteract the resultant hypophosphatemia with overproduction of PHEX transcripts that are insufficient to accommodate the enhanced substrate load. These potential pathophysiologic mechanisms for XLH and TIO provide valuable inroads to understanding phosphate homeostasis, as well as vitamin D metabolism, bone mineralization, and calcium metabolism.
