Influence of Closed-incision Negative Pressure Wound Therapy on Abdominal Site Complications in Autologous Breast Reconstruction.

Background: Closed-incision negative pressure wound therapy (ciNPWT) has shown promise in reducing surgical wound complications. Among its numerous benefits, it allows for exudate management and tension offloading from wound edges. The purpose of this systematic review and meta-analysis was to assess the efficacy of prophylactic ciNPWT versus conventional dressings on abdominal donor site complications in microsurgical breast reconstruction (MR). Methods: A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in January 2023. PubMed and Embase were searched to identify all relevant studies. Data collected included rates of total wound complications, wound dehiscence, infection, seroma, and length of hospital stay. Results: A total of 202 articles were screened, and eight studies (1009 patients) met the inclusion criteria. Use of ciNPWT was associated with a significantly lower rate of wound dehiscence (OR, 0.53; 95% confidence interval, 0.33-0.85; P = 0.0085, I2 = 0%). There was no significant difference in the rate of total wound complications [odds ratio (OR), 0.63; 95% CI, 0.35-1.14; P = 0.12, I2 = 69%], donor site infection (OR, 0.91; 95% CI, 0.42-1.50; P = 0.47, I2 = 13%), seroma (OR, 0.74; 95% CI, 0.22-2.49; P = 0.63, I2 = 57%), or length of hospital stay (SMD, 0.089; 95% CI, -0.13-0.35; P = 0.37, I2 = 29%). Conclusions: Although exudate management by ciNPWT fails to reduce surgical site infection, seroma formation, and overall length of stay, ciNPWT tension offloading properties seem to be associated with lower rates of wound dehiscence when compared with conventional dressings in abdominal-based autologous breast reconstruction.

A New Measure of Posterior Morphology in Sagittal Craniosynostosis: The Occipital Bullet Index.

INTRODUCTION: Sagittal craniosynostosis (SC) is associated with scaphocephaly, an elongated narrow head shape. Assessment of regional severity in the scaphocephalic head is limited by the use of serial computed tomographic (CT) imaging or complex computer programing. Three-dimensional measurements of cranial surface morphology provide a radiation-free alternative for assessing cranial shape. This study describes the creation of an occipital bulleting index (OBI), a novel tool using surface morphology to assess the regional severity in patients with SC. METHODS: Surface imaging from CT scans or 3D photographs of 360 individuals with SC and 221 normocephalic individuals were compared to identify differences in morphology. Cartesian grids were created on each individual's surface mesh using equidistant axial and sagittal planes. Area under the curve (AUC) analyses were performed to identify trends in regional morphology and create measures capturing population differences. RESULTS: The largest differences were located in the medial regions posteriorly. Using these population trends, a measure was created to maximize AUC. The OBI has an AUC of 0.72 with a sensitivity of 74% and a specificity of 61%. When the frontal bossing index is applied in tandem, the two have a sensitivity of 94.7% and a specificity of 93.1%. Correlation between the two scores in individuals with SC was found to be negligible with an intraclass correlation coefficient of 0.018. Severity was found to be independent of age under 24 months, sex, and imaging modality. CONCLUSIONS: This index creates a tool for differentiating control head shapes from those with SC and has the potential to allow for objective evaluation of the regional severity, outcomes of different surgical techniques, and tracking shape changes in individuals over time, without the need for radiation.

"Creation of the Scaphocephalic Index: Measurement of Global and Regional Severity in Scaphocephaly".

INTRODUCTION: The recently described frontal bossing index (FBI) and occipital bullet index (OBI) allow for quantification of scaphocephaly. A similar index examining biparietal narrowing has not been described. Addition of such an index measuring width would allow for direct evaluation of the primary growth restriction in sagittal craniosynostosis (SC) and the formation of an optimized global Width/Length measure. METHODS: CT scans and 3D photos were used to recreate scalp surface anatomy. Equidistant axial, sagittal, and coronal planes were overlaid creating a Cartesian grid. Points of intersection were analyzed for population trends in biparietal width. Using the most descriptive point coupled with the sellion's protrusion to control for head size, the vertex narrowing index (VNI) is formed. By combining this index with the FBI and OBI, the Scaphocephalic Index (SCI) is created as a tailored W/L measure. RESULTS: Using 221 control and 360 individuals with sagittal craniosynostosis, the greatest difference occurred superiorly and posteriorly at a point 70% of the head's height and 60% of the head's length. This point had an area under the curve (AUC) of 0.97 and sensitivity and specificity of 91.2% and 92.2% respectively. The SCI has an AUC of 0.9997, sensitivity and specificity >99%, and interrater reliability of 0.995. The correlation coefficients between the CT imaging and 3D photography was 0.96. CONCLUSION: The VNI, FBI, and OBI evaluate regional severity while the SCI is able to describe global morphology in patients with sagittal craniosynostosis. These allow for superior diagnosis, surgical planning, and outcome assessment, independent of radiation.

A Longitudinal, Qualitative Examination of Participant Intent-To-Change Statements that do not Match the Stated Learning Objectives of American Association of Neurological Surgeons-Sponsored Continuing Medical Education Activities.

OBJECTIVE: Continuing medical education (CME) programs are planned to provide medical professionals with the opportunity to stay abreast of new developments in their field. After each program, CME attendees are given the chance to evaluate the success of the activity in meeting its defined learning objectives. Over one-third of intent-to-change statements from CME evaluations do not match the stated learning objectives. We examined unmatched objectives and intent-to-change statements to determine their usefulness for future meeting planning. METHODS: This retrospective mixed-method content analysis used quantitative, deductive content analysis to compare intent-to-change statements and learning objectives from American Association of Neurological Surgeons-sponsored CME activities to explore unintended learning themes. RESULTS: We examined 85 CME activities with 424 meeting objectives and 1950 intent-to-change statements. Approximately 37% of intent-to-change statements were unrelated to any meeting objective, and 15% of learning objectives had no associated intent-to-change statements. Among unmatched objectives, those regarding more general subject matter often failed to be met with intent-to-change statements for multiple years, whereas those related to clinical practice were more likely to be unmatched for only 1 year. Some CME learning objectives are repeated for the same meeting for multiple years without change, although 22.6% of unmatched intent-to-change statements led to new learning objectives in subsequent years. CONCLUSIONS: An analysis of intent-to-change statements that are unmatched to meeting learning objectives is a potential avenue for understanding outcomes of CME activities. Our observations about general versus specific learning objective language may prove useful for CME planners' future educational event formulation.

Can I Ski Doc?: Return to Skiing Following Total Joint Arthroplasty.

BACKGROUND: Currently, there are little data on performance, safety, or return to downhill skiing after total joint arthroplasty (TJA). This leaves surgeons with little information for patient counseling regarding skiing. METHODS: An online survey was sent to 4360 patients who had undergone at least 1 primary TJA at a single academic center over the past 10 years (4 surgeons). The survey asked patients about their prior and current skiing activity including ability level, limitations, and reoperations. Demographics, patient-reported outcomes, and reoperations were also captured through chart review. Chi-squared, analysis of variance, and t-tests were used to compare demographics and outcomes. Paired t-tests were used to compare preoperative and postoperative skiing levels. RESULTS: Of the 763 survey respondents, the average follow-up was 4.4 years (range 0.5-10.3). In total, 35.6% had never skied, 26.5% had not skied in the 5 years prior to surgery (remote), and 37.9% had skied in the 5 years prior to surgery (recent). Seventy percent of recent skiers returned to skiing after surgery, compared to 11.9% of remote skiers. The majority of skiers, mostly advanced, returned to their prior level. There was no difference in return rates in those with a single total hip arthroplasty vs total knee arthroplasty vs multiple TJAs. Rates of reoperation were not significantly different between patients who did and did not return to skiing. CONCLUSION: The majority of recent skiers were able to return to skiing after TJA at their same level without an increase in reoperation rate. Further studies are needed to determine long-term consequences of skiing after TJA.

Longitudinal Comparison of Continuing Medical Education Learning Objectives and Intent-to-Change Statements of Participants.

INTRODUCTION: Successful completion of continuing medical education (CME) activities is often required for ongoing physician board certification, licensure, and hospital privileges. CME activities are designed to address professional knowledge or practice gaps. The authors examined participants' "intent to change" after CME activities to evaluate whether CME activity content was suitably linked with the stated learning objectives. METHODS: The authors performed a retrospective mixed-methods thematic content analysis of written and electronic records from American Association of Neurological Surgeons-sponsored CME activities. Data from 2011 through 2016 were analyzed using a quantitative, deductive content analysis approach. Data were examined for each year separately as well as longitudinally over the six consecutive years. Intent-to-change data that did not align with meeting objectives were analyzed inductively using a qualitative content analysis approach to explore potential unintended learning themes. RESULTS: The authors examined 85 American Association of Neurological Surgeons CME activities (424 CME objectives). The objectives were compared with 1950 intent-to-change statements. Thematic patterns of recurrent intent-to-change statements that matched with CME objectives included topics of resident education, complication avoidance, clinical best practices and evidence, new innovations, and novel surgical techniques. Just over a third of intent-to-change statements (37.3%) were not related to any meeting objective. Approximately a quarter of these unmatched statements led to new learning objectives in subsequent years. CONCLUSIONS: An examination of CME learning objectives and participant intent-to-change statements provides information for examination of both meeting planner and learner attitudes for future CME activity planning.
