Epidemiology of Breast Implant-Associated Anaplastic Large Cell Lymphoma in the United States: A Systematic Review.

Background: Although textured implants represent fewer than 10% of implants used in the United States, the country reports the highest incidence of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL).

Objectives: The aim of this study was to perform a systematic literature review on US-based epidemiology to update knowledge on BIA-ALCL in the United States.

Methods: Publications on US BIA-ALCL epidemiology were searched between September 2022 and March 2023 on MEDLINE (National Institutes of Health; Bethesda, MD), Embase (Elsevier, Amsterdam, the Netherlands), Web of Science (Clarivate, London, UK), and SCOPUS (Elsevier, Amsterdam, the Netherlands).

DIEP flap perfusion assessment using microdialysis versus Doppler ultrasonography: A comparative study.

Background: The increasing number of buried free-tissue transfer procedures and the need for an objective method to evaluate vascular complications of free flaps has led to the development of new technologies. Microdialysis has been used to monitor free flaps using interstitial biological markers. Previous uses mainly focused on muscular flaps.

Microwave Devices for Wearable Sensors and IoT.

The Internet of Things (IoT) paradigm is currently highly demanded in multiple scenarios and in particular plays an important role in solving medical-related challenges. RF and microwave technologies, coupled with wireless energy transfer, are interesting candidates because of their inherent contactless spectrometric capabilities and for the wireless transmission of sensing data. This article reviews some recent achievements in the field of wearable sensors, highlighting the benefits that these solutions introduce in operative contexts, such as indoor localization and microwave sensing.

Immediate prepectoral breast reconstruction using an ADM with smooth round implants: A prospective observational cohort study.

Prepectoral breast reconstruction using acellular dermal matrices (ADMs) is well established and used in candidates for nipple/skin-sparing mastectomies; it is based on many different matrices and a great variability in breast implant selection. We describe our experience and clinical outcomes using Braxon® ADMs and smooth round breast implants. Females aged 18-80 years who underwent mastectomies with immediate prepectoral reconstruction between April 2019 and April 2021 were prospectively included.

Free-style technique versus computed tomographic angiography-guided perforator selection in deep inferior epigastric perforator flap harvest: A prospective clinical study.

Background: Computed tomographic angiography (CTA) is the preferred diagnostic tool in preoperative deep inferior epigastric perforator (DIEP) flap assessment, though some surgeons prefer approaching perforator selection with intraoperative findings alone.

Methods: This prospective observational study conducted between 2015 and 2020 assessed our intraoperative decision-making "free-style" technique for DIEP flap harvest. Any patient with indication for immediate or delayed breast reconstruction using abdominally based flaps and who received preoperative CTA was enrolled.

Determining Breast Implant Prevalence: A Population Study of Italian Chest Radiographs.

Background: Current breast implant prevalence within the general population remains elusive. An accurate prevalence is critical to serve as the denominator for any assessment of breast implant-related complication. The purpose of this manuscript is to assess this prevalence in women aged 20-70 years in Italy.

Mortality Rate in Breast Implant Surgery: Is an Additional Procedure Worthwhile to Mitigate BIA-ALCL Risk?

Background: Because of poor knowledge of risks and benefits, prophylactic explantation of high BIA-ALCL risk breast implant (BI) is not indicated. Several surgical risks have been associated with BI surgery, with mortality being the most frightening. Primary aim of this study is to assess mortality rate in patients undergoing breast implant surgery for aesthetic or reconstructive indication.

Collective excitability in highly diluted random networks of oscillators.

We report on collective excitable events in a highly diluted random network of non-excitable nodes. Excitability arises thanks to a self-sustained local adaptation mechanism that drives the system on a slow timescale across a hysteretic phase transition involving states with different degrees of synchronization. These phenomena have been investigated for the Kuramoto model with bimodal distribution of the natural frequencies and for the Kuramoto model with inertia and a unimodal frequency distribution.

Assessment of Risk Factors for Rupture in Breast Reconstruction Patients with Macrotextured Breast Implants.

Background: Breast implants (BI) are widely used in plastic surgery, though they are not lifetime devices. Average life before rupture is reported to be around 10-15 years. No consensus exists regarding which factors are involved.

Background: Autologous fat transfer has an important role in breast reconstructive surgery. Nevertheless, some concerns remain with regard to its oncologic safety. The authors present a single-center, case-matching study analyzing the impact of autologous fat transfer in the cumulative incidence of local recurrences.

Total breast reconstruction with the fat-augmented latissimus dorsi (FALD) flap: High safety in a single-center uncontrolled case series.

According to ASPS, 107,238 breast reconstructions (BR) have been performed in the United States this year. The latissimus dorsi (LD) flap is used for breast reconstruction (BR), either with an implant or an extended flap harvest. Implant-enhanced LD is associated with 50% reoperation rates.

Long-Term Clinical and Aesthetic Results of a Systematic Fat Transfer Protocol for Total Breast Reconstruction after Nipple-Sparing Mastectomy.

Background: Autologous fat transfer can be safely offered for total breast reconstruction after nipple-sparing mastectomy. The aim of this study was to extend a fat transfer protocol to smokers and compare the long-term results among them and irradiated and nonirradiated patients.

Methods: One hundred seventeen breasts after nipple-sparing mastectomy were prospectively enrolled and stratified in group A (25 irradiated), group B (21 smokers), or group C (71 controls).

History of breast implants: Back to the future.

Modern breast implants are a staple of plastic surgery, finding uses in esthetic and reconstructive procedures. Their history began in the 1960s, with the first generation of smooth devices with thick silicone elastomer, thick silicone gel, and Dacron patches on the back. They presented hard consistency, high capsular contracture rates and the patches increased the risk of rupture.

Prominence of Terahertz Acoustic Surface Plasmon Excitation in Gas-Surface Interaction with Metals.

The current understanding of the dynamics of gas-surface interactions is that all of the energy lost in the collision is transferred to vibrations of the target. Electronic excitations were shown to play a marginal role except for cases in which the impinging particles have energies of several electronvolts. Here we show that this picture does not hold for metal surfaces supporting acoustic surface plasmons.
