RESUMO

BACKGROUND: Plastic surgery is among the most competitive specialties in medicine, but little is known about the attributes of programs that are most attractive to successful applicants. This study aimed to understand and provide insights regarding program characteristics that are most influential to students when ranking plastic surgery programs. METHODS: An anonymous online survey was conducted with newly matched plastic surgery residents for the integrated and combined Match in 2012 and 2013. Subjects were queried regarding their demographics, qualifications, application experiences, and motivations for residency program selection. RESULTS: A total of 92 of 245 matched plastic surgery residents (38 percent) responded to the survey. The perception of resident happiness was the most positive factor influencing program ranking, followed by high operative volume, faculty mentorship, and strong research infrastructure. Perception of a program as "malignant" was the most negative attribute. Applicants with Step 1 scores greater than 245 received significantly more interviews (p =0.001) and considered resident benefits less important (p < 0.05), but geographic location more important (p =0.005). Applicants who published more than two articles also received more interviews (p =0.001) and ranked a strong research infrastructure and program reputation as significantly more important (p < 0.05). Forty-two percent of applicants completed an away rotation at the program with which they matched, and these applicants were more likely to match at their number one ranked program (p = 0.001). CONCLUSIONS: Plastic surgery applicants have differing preferences regarding the ideal training program, but some attributes resonate. These trends can guide programs for improvement in attracting the best applicants.

RESUMO

BACKGROUND: The use of acellular dermal matrix (ADM) in tissue expander breast reconstruction has been touted to reduce capsular contracture rates and improve aesthetic outcomes. Autogenous dermal grafts have shown to be a safer and more cost-effective alternative to ADM. The purpose of this study was to compare the capsular contracture rates and long-term aesthetic outcomes of tissue expander breast reconstruction using dermal autografts with ADM-assisted reconstruction. METHODS: Patients undergoing tissue expander breast reconstruction with either ADM or dermal autografts were enrolled. Autografts were harvested from the lower abdomen. The capsular contracture rate was assessed via physical examination using the Baker scale. Standardized patient photographs were scored for aesthetic appearance on a 7-point Likert scale by blinded female observers. The ADM and autograft groups were compared using Student t test. Significance was defined as P < 0.05. RESULTS: Forty-eight patients were enrolled (76 breasts). The average follow-up time for the ADM group was 9.6 months and 9.9 months for the dermal autograft group. Twenty-seven patients received ADM, and 21 patients received dermal autograft. Capsular contracture scores were identical between the 2 groups (mean Baker grade = 1.15, P = 0.55). The average long-term aesthetic outcome score for dermal autograft-assisted breast reconstruction was 3.85, compared to 3.79 for ADM-assisted reconstruction. This difference was not statistically significant (P = 0.87). CONCLUSIONS: In addition to an improved safety profile and lower cost, dermal autograft-assisted tissue expander breast reconstruction affords equivalent aesthetic results and capsular contracture rates, when compared to ADM.

RESUMO

The use of acellular dermal matrix (ADM) in tissue expander breast reconstruction has several advantages but increased complications have been reported. Dermal autografts may offer a safer and more cost-effective alternative. The purpose of this prospective study was to compare the outcomes of tissue expander breast reconstruction using dermal autografts with ADM-assisted reconstruction. Patients undergoing tissue expander breast reconstruction with either ADM or dermal autografts were enrolled. Autografts were harvested from the lower abdomen. At each follow-up visit, patients were surveyed on a seven-point scale for scar and overall satisfaction. Biopsies taken at the time of device exchange were evaluated histologically with CD34 staining to assess tissue integration and vessel ingrowth. Expansion parameters, complications, procedural costs, and operative times were compared. Forty-eight patients were enrolled (76 breasts). Twenty-seven patients received ADM, and twenty-one patients received dermal autograft. Wound healing complications were significantly higher in the ADM group (14.8% versus 4.8%, p-value = 0.03), as were major complications (18.5% versus 0%, p-value < 0.01). Histologic vessel counts in the autograft group averaged 21 vessels/mm(2), compared to 7 vessels/mm(2) in the ADM group (p-value < 0.01). There was no difference between the two groups in scar satisfaction or overall satisfaction. Patients receiving dermal autograft had a lower incidence of major complications and delayed wound healing than patients who received ADM. Despite harvest time, the overall cost of the ADM-assisted expander placement was higher. Dermal autograft-assisted breast reconstruction offers many of the benefits of ADM, but with a lower cost and improved safety profile.

RESUMO

Structure-activity relationship (SAR) studies of novel 5-alkyl and 5-aryl/heteroaryl substituted 1,2,4-triazoles are described. The in vitro activity is compared to the pyrazole class of compounds with analogous side chains to delineate the contribution of the triazole ring nitrogen in binding to the active site. Both series are quite potent and selective in the canine whole blood (CWB) COX-2 assay, suggesting the increased binding contribution of the hydrophobic side chains.

RESUMO

The synthesis of a novel canine COX-2 selective inhibitor, 2-(3-difluoromethyl-5-phenylpyrazol-1-yl)-5-methanesulfonylpyridine, and its in vitro and in vivo profile are described. Pyrazole 8 demonstrated excellent potency and selectivity for canine COX-2 in both in vitro and ex vivo whole blood assays. This novel COX-2 inhibitor also showed a good pharmacokinetic profile (pk) following oral (po), intravenous (iv), and subcutaneous (sc) dosing and demonstrated excellent in vivo efficacy in a canine synovitis model.

RESUMO

The atomic force microscope (AFM) uses a sharp micron-scale tip to scan and amplify surface features, providing exceptionally detailed topographical information with magnification on the order of x10(6). This instrument is used extensively for quality control in the computer and semiconductor industries and is becoming a progressively more important tool in the biological sciences. Advantages of the AFM for biological application include the ability to obtain information in a direct, label-free manner and the ability to image in solution, providing real-time data acquisition under physiologically relevant conditions. A novel application of the AFM currently under development combines its surface profiling capabilities with fixed immuno-capture using antibodies immobilized in a nanoarray format. This provides a distinctive platform for direct, label-free detection and characterization of viral particles and other pathogens.

RESUMO

A series of analogues of the protein kinase C (PKC) inhibitory natural product balanol which bear modified benzophenone subunits are described. The analogues were designed with the goal of uncovering structure-activity features that could be used in the development of PKC inhibitors with a reduced polar character compared to balanol itself. The results of these studies suggest that most of the benzophenone features found in the natural product are important for obtaining potent PKC inhibitory compounds. However, several modifications were found to lead to selective inhibitors of the related enzyme protein kinase A (PKA), and several specific modifications to the polar structural elements of the benzophenone were found to provide potent PKC inhibitors. In particular, it was found that replacement of the benzophenone carboxylate with bioisosteric equivalents could lead to potent analogues. Further, a tolerance for lipophilic substituents on the terminal benzophenone ring was uncovered. These results are discussed in light of recently available structural information for PKA.
