We hypothesized that both ADI and geography are correlated with incidence of upper extremity ballistic injuries. Further, we characterize and compare 2 distinct upper extremity gunshot injury populations presenting to our institution: those sustaining violent ballistic injuries and those who suffer an accidental, self-inflicted injury. Our purpose is to evaluate the impact of geography and ADI on the pattern of upper extremity gunshot injuries in Illinois and Missouri.MATERIALS AND METHODSThis was a retrospective review of adult patients sustaining ballistic injury to the upper extremity at a single urban level I trauma center over 10 years (n = 797). Seven hundred thirty patients had home addresses in Illinois or Missouri; these addresses were geocoded and included for analysis. Mechanism of injury was self-reported. ADI was measured from the 2019 Neighborhood Atlas, in which deprivation increases from 1 to 100. Comparisons between groups were conducted with unpaired t tests, Fisher exact test, or χ2 testing, where appropriate.RESULTSAddresses constituted 259 unique census tracts, and the average number of upper extremity gunshot wound incidents per tract was 3, with a maximum of 22; 15.4% of census block tracts made up almost half (48.4%) of the total ballistic injuries in the study period; 97.7% of violent injuries occurred in Urban areas, as compared with only 60% of accidental injuries (P < 0.05). ADI and incidence of upper extremity ballistic injury were positively correlated. ADI varied significantly between patients sustaining violent (median, 94; mean, 86.1) versus accidental self-inflicted (median, 79; mean, 70.9) injuries (P < 0.05). Fifty percent of violent injuries in our data set occurred in block groups from the 2 most deprived quintiles.CONCLUSIONSUpper extremity gunshot wounds in general are concentrated in census blocks with high ADI. Violent injuries in particular are more likely to occur in urban areas with high ADI, whereas patients with accidental, self-inflicted injuries are more geographically and socioeconomically diverse. These differing populations require unique approaches to reduce incidence and morbidity.","PeriodicalId":8060,"journal":{"name":"Annals of Plastic Surgery","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were then subgrouped by setting of care (direct vs private sector care). The primary outcome was the rate and type of immediate breast reconstruction. Regression models were constructed to determine factors associated with receipt of immediate breast reconstruction.RESULTSThe final sample included 3251 women who underwent mastectomy for cancer in the direct (67.0%) or private sector care (32.6%) settings. The overall rate of immediate breast reconstruction was 29.9% with an upward trend noted throughout the study (P < 0.001).

However, the local conditions of microtia patients are complex and variable. Situations may be encountered where a series of abnormal remnant ears cannot be utilized in clinical practice. Currently, there are no literature that elaborates on this type of microtia and provides systematic treatment methods. The purpose of this article is to systematically classify them and optimize the two-stage method auricular reconstruction, to provide an effective surgical method for these patients.METHODSBased on the size, shape, and relative position of the residual ears, the unusable remnant ears were classified into three types: tiny size, abnormal shape, and relative position anomaly (over 1-cm higher than the contralateral earlobe). Fifty-three microtia patients with unusable remnant ear (54 ears) who underwent two-stage auricular reconstruction from August 2020 to August 2023 were reviewed. All patients had experienced earlobe reconstruction by using autologous rib cartilage during the first stage of surgery. Aesthetic assessments were evaluated from the naturalness of the earlobe reconstructed with autologous rib cartilage and the connection with the overall framework. The data on any complications that occurred during the follow-up period and patient satisfaction were collected.RESULTSAmong all patients, 31 had tiny size, 14 had abnormal shape, and 8 had excessively high positions. Patients were followed up for an average period of 9.2 months (6 to 12 months). No complex complications such as infection, skin necrosis, or cartilage exposure occurred. Fifty patients (94.3%) achieved excellent or good aesthetic outcomes. Fifty-one patients (96.2%) were satisfied with the reconstruction outcomes.CONCLUSIONSAn accurate assessment of the residual ear preoperatively is essential. Reconstructing and splicing the earlobe with autologous rib cartilage in cases where the residual ear cannot be utilized compensate for the defect that the soft tissue cannot provide the earlobe flap. This is an effective surgical method for the ear reconstruction in such patients.","PeriodicalId":8060,"journal":{"name":"Annals of Plastic Surgery","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They also aid weight reduction and cardiovascular health, potentially broadening their therapeutic scope. In plastic surgery, they hold promise for perioperative weight management and glycemic control, potentially impacting surgical outcomes.METHODSA comprehensive review was conducted to assess GLP-1 agonists' utilization in plastic surgery. We analyzed relevant studies, meta-analyses, and trials to evaluate their benefits and limitations across surgical contexts, focusing on weight reduction, glycemic control, cardiovascular risk factors, and potential complications.RESULTSStudies demonstrate GLP-1 agonists' versatility, spanning weight management, cardiovascular health, neurological disorders, and metabolic dysfunction-associated liver diseases. Comparative analyses highlight variations in glycemic control, weight loss, and cardiometabolic risk. Meta-analyses reveal significant reductions in hemoglobin A1C levels, especially with high-dose semaglutide (2 mg) and tirzepatide (15 mg). However, increased dosing may lead to gastrointestinal side effects and serious complications like pancreatitis and bowel obstruction. Notably, GLP-1 agonists' efficacy in weight reduction and glycemic control may impact perioperative management in plastic surgery, potentially expanding surgical candidacy for procedures like autologous flap-based breast reconstruction and influencing outcomes related to lymphedema. Concerns persist regarding venous thromboembolism and delayed gastric emptying, necessitating further investigation into bleeding and aspiration risk with anesthesia.CONCLUSIONSGLP-1 agonists offer advantages in perioperative weight management and glycemic control in plastic surgery patients. They may broaden surgical candidacy and mitigate lymphedema risk but require careful consideration of complications, particularly perioperative aspiration risk.
