Ethical aspects in managing patients diagnosed with digestive cancers; a review of literature

Numerous bioethical recommendations are now available in the complex process of communication with cancer patients. In this review, we have focused on the complex process of managing patients with different types of oncologic digestive diseases, immediately after the diagnosis is made. We have analyzed the literature data on the topic. MEDSCAPE and PubMed databases have been studied. Issues such as telling the truth to patients with digestive cancer, the physician\u27s responsibility in the psychological management of patients and their relatives, the nurses’ duties, the consented death, the practice of euthanasia and physician-assisted suicide (PAS) as well as the clinical research have been the main targets of our study

Chromium Substituted Cobalt Ferrites by Glycine-Nitrates Process

Chromium substituted cobalt ferrites (CoFe2–xCrxO4, 0 ≤ x ≤ 2) were synthesized through solution combustion method using glycine as fuel, named glycine-nitrates process (GNP). As evidenced by X-ray diffraction data (XRD), single cubic spinel phase was formed for all CoFe2–xCrxO4 (0 ≤ x ≤ 2) series. The cubic lattice parameter (a) decreases with increasing chromium content. Room temperature 57Fe Mössbauer spectra revealed the Fe3+ and Cr3+ site occupancy, the local hyperfine magnetic fields and the substitution of Fe3+ by Cr3+ in the lattice. Scanning electron microscopy (SEM) showed a refinement of particle size with the increase of Cr3+ content. Magnetic measurements from 5 K to 120 K have shown a dropping in the saturation magnetization as the chromium content increases. This behaviour has been explained in terms of substitution of Fe3+ by Cr3+ in the cubic lattice of cobalt ferrite

The Effect of Clay Type on the Physicochemical Properties of New Hydrogel Clay Nanocomposites

This study focuses on the investigation of clay type effect on the final properties of semi-interpenetrated Salecan/poly(methacrylic acid)/clay hydrogel nanocomposites. Previous studies have indicated that the presence of clay in polymer composites leads to better swelling capacity and mechanical properties as functions of clay type. On the other hand, Salecan, which is a water soluble extracellular polysaccharide, was proved to assure greater flexibility to hydrogels. These properties recommend clay and Salecan for semi-interpenetrated hydrogels preparation with specific application in biomedicine. The purpose was to determine the most suitable type of clay as well as Salecan influence for developing the desired water retention/delivery ability and mechanically enhanced semi-interpenetrating polymer network (SIPN) nanocomposites. For our investigations, we have chosen commercially available montmorillonite (ClNa) and different commercial organomodified clay (Cl30B, Cl20A and Cl15A). Several analyses results (FTIR, TGA, DMA, XRD, microscopy and swelling studies) demonstrated that not only the presence of Salecan but also the clay type influenced the structure and properties of the final nanocomposites

Low anterior rectal resection; the impact of anastomotic fistula on incidence and severity of low anterior resection syndrome

Objectives. Low anterior resection is a common surgical procedure for rectal cancer, but it is associated with a distressing complication known as Low Anterior Resection Syndrome (LARS). The incidence of LARS varies, with severe symptoms persisting in some patients even years after surgery. This study aimed to investigate the association between anastomotic leak and LARS severity in rectal cancer patients. Methods. A retrospective analysis was conducted on 100 rectal cancer patients who underwent LAR between 2017 and 2021. Patients were categorized based on LARS questionnaire responses into groups with anastomotic leakage and LARS, LARS alone, or no LARS. Various factors, including demographics, comorbidities, tumor characteristics, and surgical details, were analyzed for their association with LARS. Results. In our study, anastomotic leakage was observed in 23 patients, and 17 of them subsequently developed LARS. Male gender, age over 70, and neoadjuvant therapy were identified as risk factors for LARS. Additionally, LARS was more prevalent in patients with medium and low rectal cancers and those with a protective ostomy. Conclusion. Our findings suggest that male sex and neoadjuvant chemoradiotherapy are associated with the development of LARS in rectal cancer patients undergoing low anterior resection. The timing of stoma closure and the extent of neorectal reservoir may also impact LARS severity
