Abstract:
Background. To promote patient-centered care, it is important to understand the impact of sociodemographic factors on procedure choice for women undergoing postmastectomy breast reconstruction. In this context, we analyzed the effects of these variables on the reconstructive method chosen. Methods. Women undergoing postmastectomy breast reconstruction were recruited for the prospective Mastectomy Reconstruction Outcomes Consortium Study. Procedure types were divided into tissue expander-implant/direct-to-implant and abdominally based flap reconstructions. Adjusted odds ratios were calculated from logistic regression. Results. The analysis included 2,203 women with current or previous breast cancer and 202 women undergoing prophylactic mastectomy. Compared with women <40 years old with current or previous breast cancer, those 40 to 59 were significantly more likely to undergo an abdominally based flap. Women working or attending school full-time were more likely to receive an autologous procedure than those working part-time or volunteering. Women undergoing prophylactic mastectomy who were ≥50 years were more likely to undergo an abdominal flap compared to those <40. Conclusions. Our results indicate that sociodemographic factors affect the reconstructive procedure received. As we move forward into a new era of patient-centered care, providing tailored treatment options to reconstruction patients will likely lead to higher satisfaction and better outcomes for those we serve.

The reconstruction of cone-beam computed tomography data using filtered back-projection algorithms unavoidably results in severe artefacts. We describe how the Direct Iterative Reconstruction of Computed Tomography Trajectories (DIRECTT) algorithm can be combined with a model of the artefacts for the reconstruction of such data. The implementation of DIRECTT results in reconstructed volumes of superior quality compared to the conventional algorithms.

Abstract:
Purpose The purpose of this study is to evaluate the intra- and post-operative performance and safety of direct three dimensional printing (3DP) porous polyethylene implants in cranial reconstruction. Design/methodology/approach Prefabricated porous polyethylene implants were prepared by direct 3DP, and cranioplasty implantation was performed. Postoperative aesthetics, patient satisfaction, firmness of the implant, reactions to the implant and 3D computed tomography (CT) scanning were assessed after 2, 6, 12 and 24 months postoperatively. Findings No complications after surgery were encountered. Excellent aesthetic results were obtained in all cases, and all the patients were satisfied with the reconstruction outcome. Bone density structure was found to ingrowth into these direct 3DP porous polyethylene implants and the content increased with increasing follow-up times. Research limitations/implications This study was a pilot study conducted in a single group and evaluated in a short-term period. The bone formation and ingrowth were indirectly assessed by 3D CT evaluation. Originality/value This work reported the use and evaluation of direct 3DP porous polyethylene in middle- to large-sized cranial reconstructions. It evidently showed the bonding of implants to surrounding tissues which would result in the long-term stability and infection resistance of the implant.

Abstract:
AbstractImplant-based reconstruction (IBR) remains the most commonly utilized breast reconstruction option for post-mastectomy patients. IBR can be approached as either a one-stage reconstruction or a two-stage reconstruction. Facilitated by improvements in surgical technology and advanced techniques, one-stage reconstruction, also known as direct-to-implant (DTI) reconstruction, involves the insertion of an implant at the time of mastectomy. The decision to pursue either a DTI or a two-stage reconstruction is based on several factors, including the patient's overall health, expected risk of postoperative complications, and associated costs to both the patient and hospital.

Abstract:
The discrete Fourier transform (DFT) can be considered as an observing system, which has an input f, an output F, and a response with additive noise E. In many applications, part of the frequency spectrum/frequency information is missing or unavailable due to the passage of the time-limited signal through a band-limited system, for example, the discrete Fourier system. We suggest improving the resolution of the reconstruction of signals and images using a novel approach for the solution of the discrete Fourier system and by image enhancement. We note that the reconstruction of a time-limited signal can be simply realized by only using either the real part or the imaginary part of the DFT matrix. Therefore, based on the study of the special structure of the real and imaginary parts of the discrete Fourier matrix, a fast direct computational method is developed that utilizes explicit formulas for the truncated singular value decomposition (TSVD) obtained recently by the authors. For improving the resolution of the reconstructions, enhancement by logarithm transform is applied. This fast direct computational method is superior to other direct methods such as LU decomposition, QR decomposition, classical SVD and classical TSVD. The explicit TSVD along with the enhancement can be considered as a useful tool for signal and image reconstructions. Numerical tests for signal and image reconstructions and enhancements are given as well.

Abstract:
Annual river discharge is a critical variable for water resources planning and management. Tree rings are widely used to reconstruct annual discharge, but errors can be large when tree growth fails to respond commensurately to hydrologically important seasonal components of climate. This paper contrasts direct and indirect reconstruction as statistical approaches to discharge reconstruction for the Chemora River, in semi-arid northeastern Algeria, and explores indirect reconstruction as a diagnostic tool in reconstruction error analysis. We define direct reconstruction as predictions from regression of annual discharge on tree ring data, and indirect reconstruction as predictions from a four-stage process: (1) regression of precipitation on tree rings, (2) application of the regression model to get reconstructed precipitation for grid cells over the basin, (3) routing of reconstructed precipitation through a climatological water balance (WB) model, and (4) summing model runoff over cells to get the reconstructed discharge at a gage location. For comparative purposes, the potential predictors in both modeling approaches are the same principal components of tree ring width chronologies from a network of drought-sensitive sites of Pinus halepensis and Cedrus atlantica in northern Algeria. Results suggest that both modeling approaches can yield statistically significant reconstructions for the Chemora River. Greater accuracy and simplicity of the direct method are countered by conceptual physical advantages of the indirect method. The WB modeling inherent to the indirect method is useful as a diagnostic tool in error analysis of discharge reconstruction, points out the low and declining importance of snowmelt to the river discharge, and gives clues to the cause of severe underestimation of discharge in the outlier high-discharge year 1996. Results show that indirect reconstruction would benefit most in this basin from tree ring resolution of seasonal precipitation.

Abstract:
Conventional magnetic resonance imaging (MRI) is hampered by long scan times and only qualitative image contrasts that prohibit a direct comparison between different systems. To address these limitations, model-based reconstructions explicitly model the physical laws that govern the MRI signal generation. By formulating image reconstruction as an inverse problem, quantitative maps of the underlying physical parameters can then be extracted directly from efficiently acquired k-space signals without intermediate image reconstruction—addressing both shortcomings of conventional MRI at the same time. This review will discuss basic concepts of model-based reconstructions and report on our experience in developing several model-based methods over the last decade using selected examples that are provided complete with data and code.

Abstract:
Background. The development and improvement of reconstructive breast surgery provides medical, psychological and social rehabilitation of cancer patients, allowing them to achieve the best cosmetic and functional results. The trend towards the return of prepectoral reconstruction is associated not only with the improvement of mastectomy techniques, but also with implant coating and the emergence of highly cohesive silicone gel filling of implants. The use of polyurethane-coated endoprostheses in prepectoral reconstruction provides more reliable fixation to the surrounding tissues and allows reconstruction of the mammary glands without additional covering of the endoprosthesis.Objective: to improve the results of surgical treatment when performing a one-stage reconstruction by pre-rectal placement of polyurethanecoated implants in breast cancer. Materials and methods. In the period from April 2017 to September 2020 at the Department of Oncology and Reconstructive Plastic Surgery of the Breast and Skin of P.A. Herzen Moscow Oncology Research Institute performed 340 prepectoral breast reconstructions (direct-toimplant) using polyurethane-coated implants in breast cancer patients. A group of patients was analyzed (n = 208).Results. We noted the following complications: prolonged seroma (more than 30 days) in 39 (18.6 %) patients, red breast syndrome in 31 (14.8 %) patients, capsular contracture III–IV degree by J.L. Baker in 43 (20.57 %) patients, protrusion/extrusion of the endoprosthesis in 23 (11 %) patients, suture divergence in 8 (3.8 %) patients, necrosis in 8 (3.8 %) patients, infectious complications in 14 (6.7 %) patients, ripping in 10 (4.8 %) patients. Also, 2 (0.95 %) patients had a violation of the integrity of the endoprosthesis, and 2 (0.95 %) patients had rotation of the endoprosthesis. Conclusions. Prepectoral breast reconstruction can be used as an alternative to subpectoral reconstruction in primary operable forms of breast cancer with sufficient thickness of integumentary tissues.

We describe a run reconstruction method in which information on migration paths and travel speeds is combined with catch and escapement data to estimate harvest rate by fishery and catch by stock for Pacific salmon. Reconstruction is shown to provide comparable estimates to direct stock identification from scales in the example given. Methods of annual reconstruction are shown to be less reliable than weekly or half-weekly period reconstructions when exploitation rates change during the season. Equations are provided for incorporating differential vulnerability of stocks, and Monte Carlo methods for calculating confidence limits on harvest rate estimates are explored.

Abstract:
Abstract. Over the last decades, sea surface temperature (SST) reconstructions based on the Mg∕Ca of foraminiferal calcite have frequently been used in combination with the δ18O signal from the same material to provide estimates of the δ18O of water (δ18Ow), a proxy for global ice volume and sea surface salinity (SSS). However, because of error propagation from one step to the next, better calibrations are required to increase the accuracy and robustness of existing isotope and element to temperature proxy relationships. Towards that goal, we determined Mg∕Ca, Sr∕Ca and the oxygen isotopic composition of Trilobatus sacculifer (previously referenced as Globigerinoides sacculifer) collected from surface waters (0–10 m) along a north–south transect in the eastern basin of the tropical and subtropical Atlantic Ocean. We established a new paleotemperature calibration based on Mg∕Ca and on the combination of Mg∕Ca and Sr∕Ca. Subsequently, a sensitivity analysis was performed in which one, two or three different equations were considered. Results indicate that foraminiferal Mg∕Ca allows for an accurate reconstruction of surface water temperature. Combining equations, δ18Ow can be reconstructed with a precision of about ± 0.5 ‰. However, the best possible salinity reconstruction based on locally calibrated equations only allowed for a reconstruction with an uncertainty of ± 2.49. This was confirmed by a Monte Carlo simulation, applied to test successive reconstructions in an “ideal case” in which explanatory variables are known. This simulation shows that from a purely statistical point of view, successive reconstructions involving Mg∕Ca and δ18Oc preclude salinity reconstructions with a precision better than ± 1.69 and hardly better than ± 2.65 due to error propagation. Nevertheless, a direct linear fit to reconstruct salinity based on the same measured variables (Mg∕Ca and δ18Oc) was established. This direct reconstruction of salinity led to a much better estimation of salinity (± 0.26) than the successive reconstructions.

Abstract:
Background: Few studies have investigated the influence of patient-specific variables or procedure-specific factors on the overall cost of anterior cruciate ligament reconstruction (ACLR) in an ambulatory surgery setting. Purpose: To determine patient- and procedure-specific factors influencing the overall direct cost of outpatient arthroscopic ACLR utilizing a unique value-driven outcomes (VDO) tool. Study Design: Cohort study (economic and decision analysis); Level of evidence, 3. Methods: All ACLRs performed by 4 surgeons over 2 years were retrospectively reviewed. Cost data were derived from the VDO tool. Patient-specific variables included age, body mass index, comorbidities, American Society of Anesthesiologists (ASA) classification, smoking status, preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Computerized Adaptive Testing (PF-CAT) score, and preoperative Single Assessment Numeric Evaluation (SANE) score. Procedure-specific variables included graft type, revision status, associated injuries and procedures, time from injury to ACLR, surgeon, and operating room (OR) time. Multivariate analysis determined patient- and procedure-related predictors of total direct costs. Results: There were 293 autograft reconstructions, 110 allograft reconstructions, and 31 hybrid reconstructions analyzed. Patient-specific factors did not significantly influence the ACLR cost. The mean OR time was shorter for allograft reconstruction ( P < .001). Predictors of an increased direct cost included the use of an allograft or hybrid graft (44.5% and 33.1% increase, respectively; P < .001), increased OR time (0.3% increase per minute; P < .001), surgeon 3 or 4 (9.1% or 5.9% increase, respectively; P < .001 or P = .001, respectively), and concomitant meniscus repair (24.4% increase; P < .001). Within the meniscus repair cohort, all-inside, root, and combined repairs correlated with a 15.5%, 31.4%, and 53.2% increased mean direct cost, respectively, compared with inside-out repairs ( P < .001). Conclusion: This study failed to identify modifiable patient-specific factors influencing direct costs of ACLR. Allografts and hybrid grafts were associated with an increased total direct cost. Meniscus repair independently predicted an increased direct cost, with all-inside, root, and combined repairs being costlier than inside-out repairs. The time-saving potential of all-inside meniscus repair was not realized in this study, making implant use a significant factor in the overall cost of ACLR with meniscus repair.

Abstract:
Breast cancer is the most commonly diagnosed female cancer in the UK, with one in eight women receiving a cancer diagnosis during their lifetime. Forty per cent of women diagnosed with breast cancer undergo mastectomy as their primary therapeutic procedure. While a full range of choices is offered, breast reconstruction using implants is the patient-preferred method of reconstruction following mastectomy. This review discusses the evolution of implant-based reconstruction, focusing on the recent trend towards prepectoral breast reconstruction. Key quality indicators in the current literature are considered, including oncological outcomes, aesthetics and patient-related outcome measures, as are the health-care economics of this emerging surgical technique.
