Using CT imaging to identify sarcopenia as a risk factor for severe falls in older adults.

Background: Sarcopenia is a skeletal muscle disease primarily associated with ageing and progressive muscle decline and increases the risk of falls. The purpose of the present study was to investigate risk factors, including sarcopenia, for severe falls compared to non-severe falls. In addition, we wanted to explore possible associations between sarcopenia, bone mineral density (BMD), adipose tissue as well as clinical scores assessing frailty, nutritional status, and fall risk.

RhoB expression associated with chemotherapy response and prognosis in colorectal cancer.

Purpose: To examine the role of RhoB expression in relation to chemotherapy response, clinical outcomes and associated signaling pathways in colorectal cancer patients.

Materials And Methods: The study included 5 colon cancer cell lines, zebrafish embryos and 260 colorectal cancer patients treated with 5-fluorouracil (5-FU) and oxaliplatin (OXL). The methods consisted of CRISPR/Cas9, reactive oxygen species (ROS), caspase-3 activity, autophagy flux, in-silico RNA sequencing and immunohistochemistry.

Computed tomography-measured body composition and survival in rectal cancer patients: a Swedish cohort study.

Background: The association between body composition and survival in rectal cancer patients is still unclear. Therefore, we aimed to evaluate the impact of computed tomography (CT)-measured body composition on survival in rectal cancer patients, stratifying our analyses by sex, tumour location, tumour stage and radiotherapy.

Methods: This retrospective cohort study included 173 patients with rectal adenocarcinoma.

Survival benefit of statins in older patients with rectal cancer: A Swedish population-based cohort study.

Objectives: Increasing evidence suggests that statins may have antitumor effects but their role in rectal cancer appears inconclusive. The aim of this study was to investigate whether statins may have an impact on survival of older and younger patients with rectal cancer.

Materials And Methods: This study included 238 patients ≥70 years and 227 patients <70 years old, from the Southeast Health Care Region of Sweden, who were diagnosed with rectal adenocarcinoma between 2004 and 2013.

SPARCL1 expression increases with preoperative radiation therapy and predicts better survival in rectal cancer patients.

Purpose: The secreted protein acidic and rich in cysteine-like 1 (SPARCL1) is expressed in various normal tissues and many types of cancers. The function of SPARCL1 and its relationship to a patient's prognosis have been studied, whereas its relationship to radiation therapy (RT) is not known. Our aim was to investigate the expression of SPARCL1 in rectal cancer patients who participated in a clinical trial of preoperative RT.
