Objectives: To provide an evaluation of predictors of 6-month mortality in incident bacteraemia cases.
Methods: A retrospective population-based study of 541 adult residents of Olmsted County, MN with monomicrobial bacteraemia from 1 January 2006 through 31 December 2020. Multivariable Cox regression was used to investigate risk factors of 6-month mortality.
Results: The median (interquartile range [IQR]) age of 541 patients with bacteraemia was 66.8 (54.4-78.5) years and 39.6% were female. The median (IQR) Charlson Comorbidity Index was 6 (3-9). Overall, 144 patients died during the six-month period following their initial episode (30-day and 6-month mortality = 16.5% and 26.7%, respectively). In a multivariable analysis, older age, ICU admission, and unknown source of infection were significant predictors of increased 6-month mortality. In contrast, having an infectious diseases (ID) consultation was associated with reduced mortality in the first 2 weeks of follow-up. Secondary analyses revealed an early benefit of ID consultation during the first 30 days of follow-up and that infective endocarditis was an additional predictor of 6-month mortality.
Conclusions: To our knowledge, this investigation represents the only US population-based study evaluating predictors of mortality in patients with bacteraemia. The finding of a short-term survival benefit associated with early ID consultation may be due to more extensive diagnostic efforts.

Background: People with schizophrenia spectrum disorders are at elevated risk of HIV, and people with both HIV and schizophrenia are at elevated risk of death compared to individuals with either diagnosis alone. Limited research has assessed the HIV care cascade, and in particular retention in care, among people with HIV (PWH) and schizophrenia in the U.S.

Purpose: The purpose of this study was to develop and validate a deep-learning model for noninvasive anemia detection, hemoglobin (Hb) level estimation, and identification of anemia-related retinal features using fundus images.
Methods: The dataset included 2265 participants aged 40 years and above from a population-based study in South India. The dataset included ocular and systemic clinical parameters, dilated retinal fundus images, and hematological data such as complete blood counts and Hb concentration levels.

Department of Gastroenterology and Hepatology, Isala, Zwolle, The Netherlands.
Background: Similar to T1 colon cancer (CC), risk stratification may guide T2 CC treatment and reduce unnecessary major surgery. In this study, prediction models were developed that could identify T2 CC patients with a lower risk of lymph node metastasis (LNM) for whom (intensive) follow-up after local treatment could be considered.
Methods: A nationwide cohort study was performed involving pT2 CC patients who underwent surgery between 2012 and 2020, using data from the Dutch ColoRectal Audit, which were linked to the Nationwide Pathology Databank.

Department of Internal Medicine, Maastricht University Medical Center, Maastricht, 6229ER, the Netherlands.
Purpose: Elevated methylglyoxal (MGO) levels and altered immune cell responses are observed in diabetes. MGO is thought to modulate immune cell activation. The current study investigated whether fasting or post-glucose-load plasma MGO concentrations are associated with circulating immune cell counts and activation in a large cohort study.

Purpose: Older Black women and women living in areas of low socioeconomic status (SES) diagnosed with cervical cancer (CC) have worse overall survival (OS). The objective was to investigate associations between OS and race/ethnicity and sociodemographic factors in younger (21-64 years) and older women (≥ 65 years) diagnosed with CC using Surveillance, Epidemiology, and End Results Program data.
Methods: This retrospective, population-based cohort study included 39,000 women ≥ 21 years diagnosed with CC diagnosed between 2006 and 2020.
