AI Article Synopsis
- In October 2006, a multi-state outbreak of Salmonella enterica serovar Saintpaul occurred in Australia, linked to cantaloupe consumption, with a case-control study revealing a strong association (adjusted OR 23.9).
- The outbreak strain was identified through fecal samples and was found on the skin of cantaloupes from a specific retailer, but the exact source of contamination was not determined.
- Investigations detected multiple Salmonella species in environmental samples from farms and packing plants, highlighting the need for improved cantaloupe production practices and public health regulations.
Article Abstract
A multi-state outbreak of Salmonella enterica serovar Saintpaul infection occurred in Australia during October 2006. A case-control study conducted in three affected jurisdictions, New South Wales, Victoria and Australian Capital Territory, included 36 cases with the outbreak-specific strain of S. Saintpaul identified by multiple locus variable-number tandem repeat analysis (MLVA) in a faecal specimen and 106 controls. Consumption of cantaloupe (rockmelon) was strongly associated with illness (adjusted OR 23.9 95%, 95% CI 5.1-112.4). S. Saintpaul, with the outbreak MLVA profile, was detected on the skin of two cantaloupes obtained from an implicated retailer. Trace-back investigations did not identify the specific source of the outbreak strain of S. Saintpaul, but multiple Salmonella spp. were detected in environmental samples from farms and packing plants investigated during the trace-back operation. Cantaloupe production and processing practices pose a potential public health threat requiring regulatory and community educational interventions.

Transitions through the HIV continuum of care in people enrolling in care with advanced HIV disease in Latin America.

Objectives: Advanced HIV disease (AHD) at HIV care enrollment is common in Latin America and may bias cross-sectional care continuum estimates. We therefore explored the impact of AHD on HIV care continuum outcomes using a longitudinal approach.
Methods: We analyzed trajectories of 26,174 adult people with HIV enrolled at Caribbean, Central and South America network for HIV epidemiology (CCASAnet) sites (2003-2019) using multi-state Cox regression across five stages: (i) enrolled without antiretroviral therapy (no-ART); (ii) on ART without viral suppression (viral load ≥200 copies/m; ART + non-VS); (iii) on ART with viral suppression (viral load <200 copies/ml; ART + VS); (iv) lost to follow-up; (v) death.
Prevalence and features of allergic bronchopulmonary aspergillosis, United States, 2016-2022.

The epidemiology of allergic bronchopulmonary aspergillosis (ABPA) in the United States is not well-described. To estimate national ABPA prevalence among patients with asthma or cystic fibrosis, characterize ABPA testing practices, and describe ABPA clinical features, treatment, and 6-month outcomes. We used the 2016-2022 Merative™ MarketScan® Commercial/Medicare and Multi-State Medicaid Databases to identify cohorts of patients with 1) asthma, 2) cystic fibrosis (CF), and 3) ABPA.

Background: Medicaid expansion via the Affordable Care Act, more recent legislation and Medicaid 1115 waivers offer opportunity to increase health care access among individuals involved in the carceral system. Effective enrollment of new beneficiaries and temporary suspension and reactivation of existing Medicaid benefits upon release is key to the success of these efforts. This study aims to characterize how jails, prisons and Medicaid agencies are implementing Medicaid suspension and enrollment programs and identifies barriers and facilitators to implementation.

Study Question: Do recent changes in European Society of Human Reproduction and Embryology (ESHRE) clinical guidelines result in more comprehensive diagnosis of women with endometriosis?
Summary Answer: The latest shift in clinical guidelines results in diagnosis of more women with endometriosis but current ESHRE diagnostic criteria do not capture a sizable percentage of women with the disease.
What Is Known Already: Historically, laparoscopy was the gold standard for diagnosing endometriosis, a complex gynecological condition marked by a heterogeneous set of symptoms that vary widely among women. More recently, changes in clinical guidelines have shifted to incorporate imaging-based approaches such as transvaginal sonography and magnetic resonance imaging.
Buprenorphine and postpartum contraception utilization among people with opioid use disorder: a multi-state analysis.

Departments of Family and Community Medicine and Health and Clinical Outcomes Research, Saint Louis University School of Medicine, Saint Louis, MO, USA.
Background: The postpartum period provides an opportunity for birthing people with opioid use disorder (OUD) to consider their future reproductive health goals. However, the relationship between the use of medication for opioid use disorder (MOUD) and contraception utilization is not well understood. We used multistate administrative claims data to compare contraception utilization rates among postpartum people with OUD initiating buprenorphine (BUP) versus no medication (psychosocial services receipt without MOUD (PSY)) in the United States (US).
