Introduction Breast reconstruction with the deep inferior epigastric perforator (DIEP) flap is the current gold-standard autologous option. The profunda artery perforator (PAP) and lumbar artery perforator (LAP) flaps have more recently been described as alternatives for patients who are not candidates for a DIEP flap. The aim of this study was to review the survival and complication rates of PAP and LAP flaps, using the DIEP flap as a benchmark. Methods A literature search was conducted using PubMed, MEDLINE, Embase, BIOSIS, Web of Science, and Cochrane databases. Papers were screened by titl

Summary: The profunda artery perforator (PAP) flap, harvested from the medial aspect of the thigh, is increasingly used for breast reconstruction because of its low donor-site morbidity and ease of harvest. However, the PAP flap has a limited fat volume, which makes it difficult to use in women with larger breasts. To overcome this limitation, we have developed the “gull-wing stacked” PAP flap, which combines 2 PAP flaps with the aim of achieving adequate volume, projection, and aesthetic outcomes. We performed skin-sparing mastectomy followed by immediate reconstruction using 2 PAP flaps in 3

Background The volume of the profunda femoris artery perforator (PAP) flap limits its indications to small- and medium-sized breast reconstructions after modified radical mastectomy for cancer. We report a modified PAP flap design, including not only a vertical extension that increases its volume but also the skin surface, which suits larger breasts requiring immediate or delayed breast reconstructions and compare the results with our horizontal skin paddle PAP flap experience.

Abstract Background Given the relatively small size of thigh-based flaps and the possible necessity for a multiflap reconstruction, it is imperative to arrive at an accurate estimation of flap weight during preoperative planning. It was our objective to develop a novel technique for the preoperative estimation of profunda artery perforator (PAP) flap weight.

Background: In recent years, the profunda artery perforator (PAP) flap has gained recognition as a viable technique in autologous breast reconstruction, demonstrating low donor site morbidity and favorable reconstructive outcomes. This study aims to highlight the recent refinements using the PAP flap for breast reconstruction focusing on preoperative volume prediction. Methods: A retrospective study was conducted to evaluate the outcomes of breast reconstruction surgeries using the PAP flap at our institution between May 2018 and December 2022.

The transverse myocutaneous gracilis (TMG) and the profunda artery perforator (PAP) flap are both safe choices for autologous breast reconstruction originating from the same donor region in the upper thigh. We aimed to compare the post-operative outcome regarding donor-site morbidity and quality of life. We included 18 patients who had undergone autologous breast reconstruction with a PAP flap (n = 27 flaps). Prospective evaluation of donor-site morbidity was performed by applying the same questionnaire that had already been established in a previous study evaluating TMG flap (n = 25 flaps) ou

Background. The profunda artery perforator (PAP) flap was first applied in breast reconstruction in 2010 by Robert J. Allen. It provided an alternative for autologous breast reconstruction in addition to traditional donor sites. Currently, literature reporting its microsurgical safety and efficacy is relatively sparse and heterogeneous. Objective. To clarify the evidence regarding microsurgical safety and efficacy of PAP flap in breast reconstruction, which may contribute to future surgical decision-making. Methods. Multiple databases were systematically searched by two independent reviewers.

Abstract Background Profunda artery perforator (PAP) flap breast reconstruction has emerged as a popular choice for patients who are not optimal candidates for autologous breast reconstruction using abdominal-based techniques such as the deep inferior epigastric perforator flap. Despite increased utilization of PAP flaps, there are no previous studies on the donor-site morbidity. In this study, we present risk factors, classification of thigh wounds, and our management of donor-site wounds.

Methods: Since August 2022, SCIP/SIEA and PAP flaps have been offered for soft tissue reconstruction across all body regions. These flaps were added to the other traditionally offered free flaps, such as RFF, mSAP, ALT, DIEP, and LD. Where the defect could be equall

The linear dynamics, driven by the interactions among the non-orthogonal eigenvectors, is studied using two global instability approaches: the global eigenvalue analysis and the direct-adjoint optimization. In these global instability analysis no spatial structure is assumed a-priori for the perturbation, and the convective effects due to the high non-parallelism of the flow are taken into account.

The fretting pad and plate are modeled using isotropic elastic material properties of Ti-6Al-4V. The mating pair was subjected to a constant normal load followed by a tangential displacement. The effect of contact geometry was studied by independently varying length of the central flat region and radii of corners. Parameters important from the context of fretting viz

Abstract A method to increase the stability of periodic flap-lag dynamics in helicopter rotor blades is investigated. Instability in the flap-lag dynamics of stiff-in-plane rotors can occur as forward flight speed is increased, or if significant pitch-lag coupling is present. A method originally developed to control chaos can be applied to stabilize unstable or weakly stable periodic behavior. Stabilization is achieved using small perturbations of the mean blade pitch angle. The approach, which will be referred to as periodic active control (PAC), consists of applying discrete control to the P

Perpendicular vibrations induced by friction on a flat bearing pad is a common problem in mechanical industries. Such a coupled vibration appears as one of the characteristics for sliding squeals that might affect the bearing efficiency. The presented numerical work shows that the cyclic out-of-plane motion within a bearing pad is possible, if the vertical motion is triggered and the contact pressure, the friction, the relative sliding velocity, and material property are appropriate. The magnitude of the squeal is sensitive to the contact pressure, the friction, the damping and material proper

This study used data from the 2017 National Household Travel Survey California Add-On sample to explore how replacing the current state vehicle fuel tax with a flat-per-mile-rate road-user charge (RUC) would affect costs for different kinds of households. We first estimated how household vehicle fuel efficiency, mileage, and fuel tax expenditures vary by geography (rural vs. urban) and by income. These findings were then used to estimate how much different types of households pay in the current per-gallon state fuel tax, what they would pay if the state were to replace fuel taxes with a flat-r

One major difficulty in developing fitness-for-purpose based flaw acceptance criteria for pipeline branch connections is the calculation of the stress distributions in the vicinity of the welds. Even with the latest computer-aided modelling technologies, finite element modeling of branch connections using three-dimensional (3-D) solid elements is the only way to accurately determine the stress distributions local to the weld toes of branch connections. This report describes work to access the applicability of linear elastic fracture mechanics (LEFM) principles to a saddle-pad reinforced branch

Open science has significantly reduced the costs of scholarly publication. A 2021 study estimates the expenses of a commercial open access publisher at 55% of the price of a standard subscription article: this proportion is significantly lower for non-commercial open access publication which can be as low as 10% of the price. Numerous activities associated with publishing like commercial service, pricing or marketing are no longer necessary. The development of shared services and free software have also helped to curtailed technical costs. Open science involves a plurality of economic models t

Child-related leave can have important implications for parents and children. Increases in leave duration and benefits reduces the likelihood of parents developing depressive symptoms, have been found to improve maternal and child health, and links have been found between generous maternity leave benefits and reductions in child mortality. Child-related leave policy also has a role to play in the gender income gap, which often starts after the birth of a child. It can protect the employment relationship for mothers and assist them in returning to a job of the same level and pay. It can also al
