The most common germline checkpoint kinase 2 mutations in patients with polyps were p.S428F (n = 10), p.I157T (n = 4), and p.T476M (n = 2), with other mutations present in 1 patient each. Among patients with lower GI polyps, 9 had adenomas, 6 had serrated polyps, 1 had an inflammatory polyp, and 6 had both adenomatous and serrated polyps. Three patients (p.I157T, n = 2; p.R117G, n = 1) had more than 10 adenomas and 1 (p.G259fs) had 18 serrated polyps. Five patients (11.1%) developed colorectal adenocarcinoma, including 2 with more than 10 adenomas. Five patients with p.S428F (50%) exclusively had right-sided adenomas.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Limitations: &lt;/strong&gt;Single-center descriptive study.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Germline checkpoint kinase 2 mutations should be considered in patients with polyposis. The preponderance of right-sided adenomas in patients with p.S428F mutations suggests the importance of right-sided colonoscopy in these patients.

Twenty cases were included in each group.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Main outcome measures: &lt;/strong&gt;The use of nail polish as a baseplate was tested against the common ostomy pastes. Over 6 months, the study enrolled 40 patients who required loop ileostomy and were followed up for 8 weeks. Postoperative evaluation was performed using the City of Hope-Quality of Life ostomy and 36-Item Short Form questionnaires, as well as physical examinations conducted 1 day after surgery and at 4 and 8 weeks after surgical treatment.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Forty patients were included in the study. At all 3 time points, significant differences were observed in 36-Item Short Form scores, time, and costs spent on ostomy care. The intervention group experienced fewer peristomal skin complications (skin itching, redness, inflammation, and burning) and skin allergies at the first and second time points (p &lt; 0.05). Furthermore, none of the patients in the intervention or control group experienced rare complications such as folliculitis, candidiasis, contact dermatitis, or pyoderma gangrenosum.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Limitations: &lt;/strong&gt;Single institution.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;The utilization of nail polish as a baseplate reduces skin allergies, peristomal skin complications, and the time and financial resources spent on ostomy care. Furthermore, using nail polish has demonstrated promising results in patients' quality of life. Consequently, using nail polish emerged as the preferred choice among study participants.

Exclusion criteria were age younger than 18 years, cognitive impairment, or inability to understand Swedish/Danish. Patients completed extensive questionnaires at diagnosis and after 1 and 3 years. Clinical data were supplemented by national quality registries.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Main outcome measures: &lt;/strong&gt;The low anterior resection syndrome score, specific bowel symptoms, and patient-reported distress were assessed.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Of 1221 patients (83% response rate), 17% reported major low anterior resection syndrome 1 year after either type of resection; this finding was consistent at 3 years (17% right, 16% left). In the long-term, the only significant difference between types of resections was a high occurrence of loose stools after right-sided resections. Overall, less than one-fifth of patients experienced distress, with women reporting more frequent symptoms and greater distress. In particular, incontinence and loose stools correlated strongly with distress.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Limitations: &lt;/strong&gt;Absence of prediagnosis bowel function data.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Our study indicates that bowel function remains largely intact after colon resection, with only a minority reporting significant distress. Adverse outcomes were more common among women. The occurrence of loose stools after right-sided resection and the association between incontinence, loose stools, and distress highlights a need for postoperative evaluations and more thorough assessments beyond the low anterior resection syndrome score when evaluating patients with colon cancer.
