Non-detection of emerging and re-emerging pathogens in wastewater surveillance to confirm absence of transmission risk: A case study of polio in New York.

Infectious disease surveillance systems, including wastewater surveillance, can alert communities to the threat of emerging pathogens. We need methods to infer understanding of transmission dynamics from non-detection. We estimate a sensitivity of detection of poliovirus in wastewater to inform the sensitivity of wastewater surveillance for poliovirus using both a clinical epidemiology and fecal shedding approach.

The maturation of infant and toddler visual cortex neural activity and associations with fine motor performance.

Our understanding of how visual cortex neural processes mature during infancy and toddlerhood is limited. Using magnetoencephalography (MEG), the present study investigated the development of visual evoked responses (VERs) in cross-sectional and longitudinal samples of infants and toddlers 2 months to 3 years. Brain space analyses focused on N1m and P1m latency, as well as N1m-to-P1m amplitude.

Intratumoural expression of dihydropyrimidine dehydrogenase is an independent prognostic factor in resected pancreatic ductal adenocarcinoma treated with adjuvant gemcitabine.

Pancreatic ductal adenocarcinoma (PDAC) is associated with a poor prognosis, and biomarkers to guide treatment decisions in PDAC are generally lacking. Intratumoural expression of dihydropyrimidine dehydrogenase (DPD) is a potential prognostic parameter in patients with PDAC undergoing surgical resection and postoperative chemotherapy. In the present study, DPD was analysed by immunohistochemistry of a tissue microarray platform including a real-world cohort of 495 patients with PDAC who had undergone resection with curative intent at any of three tertiary centres, including Northern, Western and Southeastern regions of Sweden, between 1993 and 2019.

Strategies to improve recruitment in mental health clinical trials: a scoping review (RE-MIND study).

Background: Lower-than-expected recruitment continues to be one of the major causes of trial delays, and trials to improve mental health are no exception. Indeed, recruitment challenges in trials of vulnerable populations, such as those living with mental health illness, can even be exacerbated. To address this, researchers are turning to digital and online recruitment strategies, e.

The use of nutrigenomics and nutritional biomarkers with standard care of long-term recurrent metastatic rectal cancer: a case report.

Introduction: Distant metastases following standard treatment for locally advanced rectal cancer (LARC) are typically associated with poor disease-free survival. We report on a 52-year-old Australian male of Dutch ancestry with no family history of colorectal cancer or significant medical history who experienced bleeding per rectum for several months prior to a colonoscopy in July 2010. He was subsequently diagnosed with Stage IIb LARC.
