Background: Infectious complications following implant-based postmastectomy breast reconstruction (PMBR) are a significant cause of morbidity. Nationwide, antimicrobial stewardship efforts have sought to reduce the use of prophylactic antibiotics postoperatively. However, there are conflicting data regarding the utility of extended antibiotic prophylaxis (EAP) after PMBR, and many surgeons continue to prescribe them. Methods: The authors conducted a retrospective study of 1077 women who underwent immediate prosthetic PMBR from January of 2008 to May of 2020. All patients received intravenous antibiotics preoperatively and up to 24 hours postoperatively. Before October of 2016, patients were also prescribed oral antibiotics until drain removal; thereafter, this practice was abandoned. Ninety-day outcomes were compared between EAP-positive and EAP-negative patients. Descriptive statistics and multivariable logistic regression analysis were used to assess the efficacy of EAP in preventing infection-related complications. Results: There were 1004 breasts in the EAP-positive group and 683 in the EAP-negative group. Three hundred sixty-one reconstructions (21.4%) were prepectoral. Multivariable analysis demonstrated no difference in surgical-site infection (OR, 0.83; 95% CI, 0.56 to 1.25; P = 0.38), admission (OR, 0.78; 95% CI, 0.41 to 1.48; P = 0.44), reoperation (OR, 1.01; 95% CI, 0.68 to 1.48; P = 0.97), or explantation rates (OR, 1.06; 95% CI, 0.66 to 1.71; P = 0.81) between the EAP groups. The EAP-positive group was more likely to develop Gram-negative infections (P < 0.001). Thirteen EAP-positive women (2.0%) developed allergic reactions, and four (0.6%) developed Clostridium difficile colitis attributable to the EAP. Conclusions: EAP after PMBR did not improve outcomes. Although use of EAP did not appear to worsen clinical outcomes, marked differences in the microbiology of associated infections may render them more difficult to treat. Moreover, a small but significant proportion of women experienced adverse reactions to the EAP. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

BackgroundIn this study, we examined the implementation and efficacy of Operation Change, a community-based, culturally sensitive program to stimulate behavioral changes in activity level and improve musculoskeletal health in African-American (AA) and Hispanic/Latina (H/L) women with obesity and early-stage osteoarthritis.MethodsSixty-two women (32 AA and 30 H/L), 40–75 years old, with nontraumatic knee pain and body mass index values > 30, participated in a 12-week program of presentations, motivational interviewing, goal setting, and physical activities. Assessments (at 0, 6, and 12 weeks) included a demographic questionnaire, physical assessment, timed 50-ft walking test, Western Ontario and McMaster Universities Arthritis Index (WOMAC), Short Form-36 Health Survey (SF-36), 8-Item Physical Health Questionnaire (PHQ-8), and motivational interview assessment.ResultsWalking time improved significantly for H/L women (P < 0.0001) but not AA women (P = 0.0759). Both groups had significant mean weight loss (P < 0.05) with high variability among individuals. WOMAC scores for both groups indicated decreased pain (P < 0.0001) and stiffness (P < 0.0001) and improved physical functioning (P < 0.0001) by 12 weeks. SF-36 results were comparable to those of the WOMAC. PHQ-8 results improved significantly for H/L women (P < 0.0001) but not AA women (P = 0.077). Participants scored the motivational interviewing component of the program favorably.ConclusionsParticipation in Operation Change increased physical activity, resulting in improvements in pain and function scores. This supports a new paradigm for behavioral modification that helps AA and H/L women take an active role in living with osteoarthritis.

rosthetic-based breast reconstruction after mastectomy remains the most common method of breast reconstruction in the United States. Skin-sparing mastectomies have traditionally been performed using an elliptical incision to reduce the skin envelope. However, the elliptical skin-sparing mastectomy (ESSM) leads to a flattened, "boxy" breast shape that is not aesthetically pleasing and often does not provide good symmetry with the contralateral breast, particularly in women with large and/or ptotic breasts. The Wise-pattern skin-sparing mastectomy (WSSM) has been described as an alterna-
