In this article, we describe the design and rationale for the CanStem111P clinical trial, a multicenter, randomized, open-label, Phase III study designed to determine the efficacy and safety of combining napabucasin with nab-paclitaxel and gemcitabine for first-line ...

Towards personalized treatment in atopic dermatitis.

For many years, oral immunosuppressive drugs such as cyclosporine A, azathioprine, mycophenolic acid and methotrexate were the only treatment options, in addition to topical treatment, in patients with severe atopic dermatitis (AD). Dupilumab, a monoclonal antibody targeting the IL-4 receptor alpha, is the first antibody-based treatment commercially available for the treatment of AD. In the near f...

Head Trauma Exposure in Mixed Martial Arts Varies According to Sex and Weight Class.

Brain injury arising from head trauma is a major concern in mixed martial arts (MMA) because knockout (KO) and technical knockout (TKO) are frequent fight outcomes. Previous studies have shown a high incidence of matches ending due to strikes to the head but did not consider weight categories and female fights. This study aimed at analyzing match stoppages in MMA and the exposure to head trauma di...

Affective and Cognitive Attitudes on Cervical Health Behaviors Among Asian American Women.

Cervical cancer is a major cause of death for Vietnamese and Korean American women, yet their screening rates remain low. This study explored factors influencing cervical health behaviors of these populations, using a 2-dimensional model (ie, affect and cognition) of attitude structure approach. Semistructured interviews were conducted with 33 participants. A semantic content analysis was used to ...

A Simple Method of Intracorporeal "W-shaped" Liver Retraction Technique for Minimally Invasive Gastric Cancer Surgery.

Minimally invasive gastric cancer surgery requires an extended liver retraction in order to provide optimal operative view, working space for lymph node dissection, and esophageojejunal reconstruction. Ideally, it should avoid reposition of the retractor, additional skin incision or puncture, and liver parenchyma injury. Herein, we introduced an intracorporeal W-shaped liver retraction technique (...

Confirming the Clinical Safety and Feasibility of a Bundled Methodology to Improve Cardiopulmonary Resuscitation Involving a Head-Up/Torso-Up Chest Compression Technique.

Combined with devices that enhance venous return out of the brain and into the thorax, preclinical outcomes are improved significantly using a synergistic bundled approach involving mild elevation of the head and chest during cardiopulmonary resuscitation. The objective here was to confirm clinical safety/feasibility of this bundled approach including use of mechanical cardiopulmonary resuscitatio...

Desmoplasia in Lymph Node Metastasis of Pancreatic Adenocarcinoma Reveals Activation of Cancer-Associated Fibroblasts Pattern and T-helper 2 Immune Cell Infiltration.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by a peritumoral proliferation of fibroblasts and extracellular matrix production known as desmoplasia. We aimed to study desmoplasia in PDAC lymph node (LN) metastases.

Incidence and Mortality Rates of Second Pancreatic Cancer Among Survivors of Digestive Cancers: A Nationwide Population-Based Study.

We analyzed the incidence and mortality rates of second pancreatic ductal adenocarcinoma (PDAC) among survivors of digestive cancers in South Korea.

Long Non-Coding RNA TFAP2A-AS1 Inhibits Cell Proliferation and Invasion in Breast Cancer via miR-933/SMAD2.

BACKGROUND It is well documented that long non-coding RNAs (lncRNAs) are involved in the progression of multiple human tumors by sponging microRNAs (miRNAs). However, whether lncRNA TFAP2A-AS1 plays a role in the tumorigenesis of breast cancer (BC) remains undetermined. MATERIAL AND METHODS Real-time PCR (qRT-PCR) assay was performed to detect the relative mRNA expression of TFAP2A-AS1 and miR-933...

A general dose-response relationship for chronic chemical and other health stressors and mixtures based on an emergent illness severity model.

Current efforts to assess human health response to chemicals based on high-throughput in vitro assay data on intra-cellular changes have been hindered for some illnesses by lack of information on higher-level extracellular, inter-organ, and organism-level interactions. However, a dose-response function (DRF), informed by various levels of information including apical health response, can represent...

Ornithine decarboxylase antizyme inhibitor 2 (AZIN2) is a signature of secretory phenotype and independent predictor of adverse prognosis in colorectal cancer.

Ornithine decarboxylase (ODC) is the rate-limiting enzyme of polyamine synthesis. The two ODC antizyme inhibitors (AZIN1) and (AZIN2) are regulators of the catalytic activity of ODC. While AZIN1 is a regulator of cell proliferation, AZIN2 is involved in intracellular vesicle transport and secretion. There are no previous reports on the impact of AZIN2 expression in human cancer. We applied immunoh...

Effects of increased space allowance on animal welfare, meat and ham quality of heavy pigs slaughtered at 160Kg.

Sixty barrows (Body Weight-BW- range: 23.9-160 kg) were allotted to two experimental groups (6 pens of 5 pigs each): the control group was kept at a space allowance of 1m2/head; the second group was kept at 1.3m2/head. Behaviour, growth parameters, carcass and meat quality were assessed, as well as fat and cured ham quality. Results showed that pigs raised at 1.3m2/head spent more time laying (par...

Quality of teamwork in multidisciplinary cancer team meetings: A feasibility study.

Tumor boards (TB) play an important role to formulate a management plan for the treatment of patients with a malignancy. Recent evidence suggests that optimally functioning teams (teamwork, communication and decision making) are major prerequisites to conduct efficient TB meetings. The aims of this study were i) to use a readily published tool as a template for the development of a teamwork perspe...

A hybrid gene selection algorithm based on interaction information for microarray-based cancer classification.

We address gene selection and machine learning methods for cancer classification using microarray gene expression data. Due to the high dimensionality of microarray data, traditional gene selection algorithms are filter-based, focusing on intrinsic properties of the data such as distance, dependency, and correlation. These methods are fast but select far too many genes to use for the classificatio...

Susceptibility to Oral Antiseptics and Virulence Factors Ex Vivo Associated with Candida spp. Isolated from Dental Prostheses.

To isolate Candida spp. from dental prosthesis users' saliva and to evaluate the isolates for the presence of several virulence factors. This research also aimed to investigate the antifungal activity of 3 commercial mouthwashes/oral antiseptic formulations containing 0.12% chlorhexidine, 0.07% cetylpyridinium, or 0.075% cetylpyridinium against planktonic and sessile (biofilm mode) yeast cells.

Implementing Reverse Phase Protein Array profiling as a sensitive method for the early pre-clinical detection of off-target toxicities associated with Sunitinib Malate.

The tyrosine kinase inhibitor (TKI) sunitinib is a multi-targeted agent approved across multiple cancer indications. Nevertheless, since approval, data has emerged to describe a worrisome side effect profile including hypertension, hand-foot syndrome, fatigue, diarrhoea, mucositis, proteinuria and (rarely) congestive heart failure. It has been hypothesised that the observed multi-parameter toxicit...

Rates of symptomatology are lower in recurrent sinonasal malignancy than in other recurrent cancers of the head and neck: a multi-institutional study.

Sinonasal malignancies are a rare subset of head and neck tumors, and surveillance strategies after definitive tumor treatment are often generalized from those for overall head and neck cancer outcomes data. However, recent literature suggests that the posttreatment period in sinonasal cancer is fundamentally different and a more tailored surveillance approach may be beneficial. Although rates of ...

Posterior fossa ependymoma (PFE) comprises 2 groups, PF group A (PFA) and PF group B (PFB), with stark differences in outcome. However, to the authors' knowledge, the long-term outcomes of PFA ependymoma have not been described fully. The objective of the current study was to identify predictors of survival and neurocognitive outcome in a large consecutive cohort of subgrouped patients with PFE ov...

The impact of psychosocial stress and stress management on immune responses in patients with cancer.

The range of psychosocial stress factors/processes (eg, chronic stress, distress states, coping, social adversity) were reviewed as they relate to immune variables in cancer along with studies of psychosocial interventions on these stress processes and immune measures in cancer populations. The review includes molecular, cellular, and clinical research specifically examining the effects of stress ...

"You probably can't feel as safe as normal women": Hispanic women's reactions to breast density notification.

Patient advocacy has led to state-level legislative mandates for the release of personal mammographic breast density information to women undergoing screening mammography. More research is needed to understand the impact of this information on women's perceptions and mammography screening behavior.

The relationship between obesity in adolescence and pancreatic cancer in adulthood.

Association between primary language, a lack of mammographic screening, and later stage breast cancer presentation.

Health determinants are known to influence the stage of breast cancer presentation, but it is unclear to what extent language affects stage. This study investigates whether non-English-speaking (NES) patients present at a later stage than their English-speaking (ES) counterparts and whether language is associated with mammographic screening.
