Colonic tuberculosis mimicking malignancy: a multidisciplinary medical and surgical approach.

Colonic tuberculosis (TB) is a rare form of extrapulmonary TB with nonspecific clinical presentations such as weight loss, abdominal pain and fever. It is often misdiagnosed, as the presentations mimic other more common diseases such as colon cancer and inflammatory bowel diseases, especially in those countries with low TB incidence. Although a combination of CT imaging, colonoscopy and histopathology forms the essential part of the diagnostic assessment, the high variability and low specificity of each investigation may delay or overlook the diagnosis.

Perforated imprinting on high moisture meat analogue confers long range mechanical anisotropy resembling meat cuts.

Meat cuts, when cooked and masticated, separate into fibrous structures because of the long-range mechanical anisotropy (LMA) exhibited by muscle fascicles, which is not fully recapitulated in alternative proteins produced using molecular alignment technology like high moisture extrusion. We have developed a scalable perforated micro-imprinting technology to greatly enhance LMA in high moisture meat analogue (HMMA). By imprinting 1 mm thick HMMA sheets with perforated patterns (optimized by AI), we observed up to 5 × more anisotropic separation of fibrous structures in a one-dimensional pulling LMA analysis, to match the fibrousness of the cooked chicken breast, duck breast, pork loin and beef loin.

Assessing the Operational Characteristics of the Individual Causal Association as a Metric of Surrogacy in the Binary Continuous Setting.

In a causal inference framework, a new metric has been proposed to quantify surrogacy for a continuous putative surrogate and a binary true endpoint, based on information theory. The proposed metric, termed the individual causal association (ICA), was quantified using a joint causal inference model for the corresponding potential outcomes. Due to the non-identifiability inherent in this type of models, a sensitivity analysis was introduced to study the behavior of the ICA as a function of the non-identifiable parameters characterizing the aforementioned model.

Reliability of Anthropometric Measurement of Young Children with Parent Involvement.

The purpose of this study was to determine the reliability of anthropometric measurements between two trained anthropometrists working in a team and one trained anthropometrist working with a child's parent/caregiver in a primary health care setting. An observational study to determine measurement reliability was conducted in a primary care child research network in Canada. In total, 120 children 0-5 years old had their anthropometric measurement taken twice by two trained anthropometrists working in a team and twice by one trained anthropometrist working with a child's parent/caregiver.

Outcomes of Patients With Newly Diagnosed AML and Hyperleukocytosis.

Purpose: AML presenting with hyperleukocytosis is associated with poor outcomes. We aim to understand the factors associated with early mortality and overall survival (OS) to help guide management and improve early mortality.

Methods: We retrospectively reviewed data from 129 consecutive patients with newly diagnosed AML and a WBC count ≥100 × 10/L between January 2010 and April 2020.
