Preauricular sulcus: Radiological incidence in the female gender in a multicultural population.

Introduction: The preauricular sulcus is a bony groove seen on the inferior aspect of the iliac bone. It is thought and accepted to be an indicator of female gender. To our knowledge, this study would be the first to examine the sulcal incidence in a multicultural population.

Ability of malnutrition screening and assessment tools to identify computed tomography defined low muscle mass in colorectal cancer surgery.

Background: Malnutrition and low muscle mass are independently associated with poor outcomes in colorectal cancer (CRC). However, tools to identify low muscle mass are limited in the clinical setting. We investigated the ability of existing malnutrition screening and assessment tools to identify low muscle mass assessed by computed tomography (CT).

The association between sarcopenia and quality of life in patients undergoing colorectal cancer surgery: an exploratory study.

Objective: To describe changes in health-related quality of life (QoL) from before colorectal cancer (CRC) surgery to 1 and 3-month post-surgery in patients diagnosed pre-operatively as sarcopenic or non-sarcopenic by computed tomography (CT) analysis.

Methods: Secondary analysis of a prospective observational cohort study with one pre-operative and two post-operative assessments. Patient-reported outcome measures (PROMs) were collected at each timepoint using Functional Assessment of Cancer Therapy-Colorectal and the EuroQol-5D (EQ-5D) questionnaires.

Does dual-energy computed tomography pulmonary angiography (CTPA) have improved image quality over routine single-energy CTPA?

Introduction: The aim of this study is to compare the diagnostic sensitivity between dual-energy computed tomography pulmonary angiography (CTPA) studies and routine single-energy CTPA studies.

Methods: A total of 117 patients with clinically suspected pulmonary embolism were examined with dual-energy CTPA (DECT) and reformatted single-energy multidetector CTPA (MDCT) studies. Two independent radiologists assessed the image quality of the CTPAs with objective and subjective parameters, including by assigning an image quality score out of 10 for each study.

Immunotoxic destruction of distinct catecholaminergic neuron populations disrupts the reproductive response to glucoprivation in female rats.

We tested the hypothesis that hindbrain catecholamine (norepinephrine or epinephrine) neurons, in addition to their essential role in glucoprivic feeding, are responsible for suppressing estrous cycles during chronic glucoprivation. Normally cycling female rats were given bilateral injections of the retrogradely transported ribosomal toxin, saporin, conjugated to monoclonal dopamine beta-hydroxylase antibody (DSAP) into the paraventricular nucleus (PVN) of the hypothalamus to selectively destroy norepinephrine and epinephrine neurons projecting to the PVN. Controls were injected with unconjugated saporin.
