Article Abstract
Purpose: Adolescents aged 13-18 years bear a large burden of sexually transmitted infections (STIs) and changing adolescent sexual risk behavior is a key component of reducing this burden. We demonstrate a novel publicly available modeling tool (teen-SPARC) to help state and local health departments predict the impact of behavioral change on gonorrhea, chlamydia, and HIV burden among adolescents.
Methods: Teen-SPARC is built in Excel for familiarity and ease and parameterized using data from CDC's Youth Risk Behavior Surveillance System. We present teen-SPARC's methods, including derivation of national parameters and instructions to obtain local parameters. We model multiple scenarios of increasing condom use and estimate the impact on gonorrhea, chlamydia, and HIV incidence, comparing national and New York State (NYS) results.
Results: A 1% annual increase in condom use (consistent with Healthy People 2020 goals) could prevent nearly 10,000 cases of STIs nationwide. Increases in condom use of 17.1%, 2.2%, and 25.5% in NYS would be necessary to avert 1000 cases of gonorrhea, 1000 cases of chlamydia, and 10 cases of HIV infection, respectively. Additional results disaggregate outcomes by age, sex, partner sex, jurisdiction, and pathogen.
Conclusion: Teen-SPARC may be able to assist health departments aiming to tailor behavioral interventions for STI prevention among adolescents.

Nocturnal Oxygen Therapy for Central Sleep Apnea in Patients with Heart Failure: A Multi-site, Double-blind, Sham-controlled Randomized Clinical Trial (LOFT-HF).

Rationale: There are insufficient data to inform the management of central sleep apnea (CSA) in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Nocturnal oxygen therapy (NOT) has been postulated to benefit CSA patients with HFrEF, but has not been rigorously studied.

Background: In 2019, seven county correctional facilities (jails) in Massachusetts initiated pilot programs to provide all Food and Drug Administration-approved medications for opioid use disorder (MOUD).
Methods: This observational study used linked state data to examine postrelease MOUD receipt, overdose, death, and reincarceration among persons with probable opioid use disorder (OUD) in carceral settings who did or did not receive MOUD from these programs from September 1, 2019, through December 31, 2020. Log-binomial and proportional-hazards models were adjusted for propensity-score weights and baseline covariates that remained imbalanced after propensity-score weighting.

The Dark Energy Spectroscopic Instrument (DESI) is a massively parallel spectroscopic survey on the Mayall telescope at Kitt Peak, which has released measurements of baryon acoustic oscillations determined from over 14 million extragalactic targets. We combine DESI Data Release 2 with CMB datasets to search for evidence of matter conversion to dark energy (DE), focusing on a scenario mediated by stellar collapse to cosmologically coupled black holes (CCBHs). In this physical model, which has the same number of free parameters as ΛCDM, DE production is determined by the cosmic star formation rate density (SFRD), allowing for distinct early- and late-time cosmologies.
