The sacral area is the most common site for pressure injuries (PIs) associated with prolonged supine bedrest. In previous studies, an anisotropic multilayer prophylactic dressing was found to reduce the incidence of PIs and redistribute pressure. The purpose of the current study was to further investigate relationships between design features and biomechanical efficacy of sacral prophylactic dressings. Using computer modeling, the anisotropic multilayer dressing and a hypothetical dressing with different mechanical properties were tested under dry and 3 levels of moist/wet conditions. Sixteen (16) finite element model variants representing the buttocks were developed. The model variants utilized slices of the weight-bearing buttocks of a 28-year-old healthy woman for segmentation of the pelvic bones and soft tissues. Effective stresses and maximal shear stresses in a volume of interest of soft tissues surrounding the sacrum were calculated from the simulations, and a protective endurance (PE) index was further calculated. Resistance to deformations along the direction of the spine when wet was determined by rating simulation outcomes (volumetric exposures to effective stress) for the different dressing conditions. Based on this analysis, the anisotropic multilayer prophylactic dressing exhibited superior PE (80%), which was approximately 4 times that of the hypothetical dressing (22%). This study provides additional important insights regarding the optimal design of prophylactic dressings, especially when exposed to moisture. A next step in research would be to optimize the extent of the anisotropy, particularly the property ratio of stiffnesses (elastic moduli).

Physiological, psychological, and social problems may affect adaptation to living with a stoma. A descriptive, cross-sectional study was conducted between March 2017 and June 2017 among patients culled from a manufacturer's database to identify factors that influence psychosocial adjustment in Chinese patients with an enterostoma. Patients with a history of ostomy surgery ≥1 month prior and who were ≥18 years of age, completed a primary school education, and able to communicate in Chinese were eligible to participate unless they had a history of psychosis, cognitive impairment, or participation in other research programs. After providing informed consent, participants completed a questionnaire that addressed demographic (age, gender, employment, educational level, marital status, medical payment method, living status, and area of residence) and stoma-related (date of surgery, preoperative stoma siting, ostomy appliance type, peristomal complications, regular defecation, stoma self-care ability, stoma-related communication with medical staff, level of understanding regarding stoma knowledge and care skills, appliance change knowledge/experience, and leakage history) factors. Social support was assessed using the 10-item Social Support Revalued Scale (SSRS), and 3 dimensions of adjustment (acceptance, continuous worry, and positive life attitude) were assessed using the 20-item Chinese version of the Ostomy Adjustment Inventory (OAI). Questionnaires were administered via an online survey platform. Data were analyzed descriptively, and single-factor analysis and stepwise multiple linear regression were applied to identify the factors that influenced the adjustment level. Incomplete (missing >2 questions), incorrect, or hastily completed (within 600 seconds) records were excluded from analysis. Of the 1109 persons who returned the questionnaire, 1010 (91.1%) completed the entire survey (564 men [55.8%] and 446 women [44.2%], mean age 56.62 ± 15.62 years); 823 (81.5%) had a colostomy and 187 (18.5%) had an ileostomy. The OAI dimension continuous worry was negatively and significantly associated with all 3 dimensions of the SSRS, including subjective support (r = 0.259), objective support (r = 0.259), and utilization of support (r = 0.289), while the dimension acceptance was positively associated with both subjective support (r = 0.082) and objective support (r = 0.074) (all P values <.05). Using multiple linear regression, residence area, peristomal complication, regular defecation, leaking, self-care ability, communication with medical staff regarding ostomy, understanding knowledge or skill needed for stoma care, utilization of social support, and total score of social support were found to be significantly associated with ostomy adjustment level (all P values <.05). Patients living in an urban area, with no history of peristomal complications, who had regular defecation, had not experienced leaking, had better self-care ability, frequently co

Three-dimensional (3D) printing technology can generate objects in almost any shape and geometry. This technique also has clinical applications, such as the fabrication of specific devices based on a patient's anatomy. A demonstration study is presented of a 54-year-old man who needed a thermoplastic splint to limit arm movement while a dehisced left shoulder wound healed. The patient's upper extremity was scanned using the appropriate noncontact scanner and 3D technology software, and the polylactic acid splint was printed over the course of 66 hours. This patient-specific splint was worn during the day, and after 2 weeks the wound was healed sufficiently to permit hospital discharge. Creation of an individualized splint is one of many potential medical uses of 3D technology. Although the lengthy printing time imposes limitations, the implications for practice are positive.

Having ostomy surgery changes a person's life. To assess adjustment to life with an ostomy and quality of life (QOL) 1 year after ostomy surgery, a prospective, explorative study was conducted among patients of a stoma clinic at a university hospital in Sweden. All consecutive patients who had undergone nonemergent or emergency surgery involving formation of an ostomy and who received regular follow-up at the ward and at the outpatient clinic during the first year by an enterostomal therapist (ET) were prospectively included in the study; their demographic information (including age, gender, diagnosis/reason for an ostomy, nonemergent or emergency surgery, ostomy type, preoperative counselling/siting [Yes/No], self-sufficiency in stoma care, professional activity, and whether they lived with a spouse/partner) was recorded upon admission to the study. Participants independently completed the Ostomy Adjustment Scale (OAS), a 36-item instrument, with each response scored from worst to best adjustment (1 to 6) for a total score ranging from 36-216. The tool addresses 5 factors: normal functioning, functional limitations, negative affect, positive role function, and positive affect. In addition, QOL was assessed using a visual analogue scale (0 to 100 mm) along with 2 open-ended QOL questions. Quantitative and qualitative data were included on the same questionnaire and were entered into an Excel file by 2 of the researchers. The quantitative data were transferred to statistical software for analysis; the qualitative data were analyzed according to Graneheim and Lundman. Descriptive statistics were used for quantitative data and based on nonparametric analysis, and qualitative data were analyzed using content analysis. Of the 150 patients eligible for inclusion (82 women, 68 men, median age 70 [range 21-90] years), 110 (73%) underwent nonemergent surgery, 106 (71%) had a colostomy, and 44 (29%) had an ileostomy. Most ostomies were created due to cancer (98, 65%) and inflammatory bowel disease (28, 19%), and 90% of participants were self-sufficient in ostomy care. The overall median score on the OAS was 162 with no significant differences between genders and diagnoses. The OAS scores for patients who did versus did not have preoperative counselling by an ET were 163 and 150, respectively (P = .313). Mean OAS scores were 136 for patients with cancer and an ileostomy and 163 for patients with cancer and a colostomy. Patients with cancer and an ileostomy had a significantly worse adjustment (mean 3.6 ± 1.32) than patients with cancer and a colostomy (mean 4.4 ± 1.21) in the factor Normal function (P = .015). Lowest adjustment scores were in the areas of sexual activities and attractiveness and participating in sports and physical activities; the highest scores concerned contact with an ET, feeling well informed, and knowing the correct methods of handling the ostomy. The median score for QOL for all patients was 76 (interquartile range 59-86). Three

Adenocarcinoma that occurs at the ileostomy site after proctocolectomy (TPC) with an end ileostomy for ulcerative colitis (UC) and/or familial adenomatous polyposis (FAP) is a late and uncommon complication. To ascertain the rate of adenocarcinoma at the empirical ileostomy site following TPC, a review of the literature was conducted. PubMed, MEDLINE, the Cumulative Index of Nursing and Allied Health Literature, EMBASE, Google search engine, and the Cochrane Database were investigated for research published between January 1975 and December 2016. Search criteria included English language and human-only publications; broad search terms related to UC, FAP, ileostomy procedures, and dysplasias were used. Abstracts were eliminated if they were foreign language and nonhuman studies; editorials also were excluded. Secondary and hand/manual searches of reference lists, other studies cross-indexed by authors, reviews, commentaries, books, and meeting abstracts also were performed. Data extracted included age at diagnosis, operation technique, interval to ileostomy cancer, age when cancer was diagnosed, histology for both UC and FAP patients, and subsequent treatment. Papers were included on the basis of available evidence for each specific point of interest. Final and conclusive agreement was assessed with the k statistics during the title review and abstract review. Studies that did not report original data also were excluded. A total of 5753 publications were identified; 5697 publications did not conform to inclusion criteria and were eliminated. Among the reviewed publications (all case studies), 57 patients were diagnosed with ileostomy adenocarcinoma after TPC; 42 had UC, and 15 had FAP. The interval between TPC operation and ileostomy cancer diagnosis ranged from 3 to 51 years for UC and from 9 to 40 years for FAP, with a mean interval of 30 and 26 years, respectively. Biopsies were performed of all polypoid lesions found at the stoma site. Patients were treated with wide excision and refashioning (diversion) of the stoma. While adenocarcinoma arising at the mucocutaneous junction at the ileostomy site with adjacent skin invasion after TPC for UC and FAP appears to be rare, patients and clinicians need to be aware of this potential complication even years after surgery and regular screening is recommended.
