Controlling the Traffic in the Union and Confederate States
Authors: Bever Megan L.
Published: September 2023

Loyal and Confederate states diverged when it came to controlling the liquor traffic during the war. Since the mid-1850s, license laws that regulated the traffic had been commonplace in states that would remain in the Union. Although temperance reformers wanted prohibition (and advocated for it by linking it to saving the Union), regulation and taxation triumphed in loyal states during the war. In the Confederacy, seven states passed prohibition on distilling during the war, citing a need to conserve grains and fruits to feed civilians. By doing so, Confederate states set themselves up for showdowns with Richmond, because the military continued to produce its own liquor and contract with civilian sellers to manufacture the liquor it needed for its medical departments.
No Rural Bowl of Milk
Authors: Goode Abby L.
Published: September 2023

This chapter highlights the racial and reproductive fears that drove early sustainability rhetoric, examining Herman Melville’s novel Pierre (1852) alongside his farm writings. Set in New York City and the Hudson Valley in the 1840s, Pierre dramatizes the fears of land reformers, labor radicals, and nativists who promoted agrarian principles as a solution to what they saw as an increasingly unsustainable society. At the time, newspapers such as The Albany Freeholder and Young America! deployed an early form of sustainability rhetoric, critiquing aristocratic land-owning practices and lamenting the miserable condition of the urban poor and working class. They described the population of greater New York as degenerate and agriculturally damaging, contrasting it with a specifically demographic agrarian ideal—a sprawling, fertile, American population, evenly dispersed across small plots of abundant farmland. Inverting this ideal, Pierre reveals the reproductive subtext of this rhetoric: the idea that sexual disorder and racial intermingling enfeeble population fertility and agricultural productivity.
Gothic Fertility and Other Tropical Nightmares
Authors: Goode Abby L.
Published: September 2023

This chapter shows how the early American plantation-based tropics, especially the West Indies, came to epitomize unsustainability and how racial homogeneity became a defining feature of agrotopias. For Thomas Jefferson and J. Hector St. John de Crèvecoeur, the tropics were unsustainable—characterized by racial degeneracy and reproductive chaos. Lending credence to Jefferson’s claims about tropical degeneracy, Crèvecoeur’s “Sketches of Jamaica and Bermudas and Other Subjects” (1773) shows these climates threatening to corrupt a Pennsylvanian farmer and engulf the region in revolutionary violence. Fulfilling Crèvecoeur’s prophecies, Leonora Sansay’s Secret History (1808) portrays the Haitian Revolution as a demographic disaster through a combination of reproductive and horrific imagery that I call gothic fertility. Ultimately, across these texts, it is the possibility of racial intermingling, more so than a degenerative climate, that directly threatens a sustainable future in the Americas.
African Agrotopias
Authors: Goode Abby L.
Published: September 2023

Chapter three turns to a black nationalist corpus that considers the West Indies and other non-US sites as possible agrotopias, protected from the threat of extinction, enslavement, and erasure. These writings imagine fertile, independent, black agrotopias outside the US—in the southern Americas, the Texas borderlands, and on the eastern coast of Africa. From Martin Delany’s The Condition, Elevation, Emigration, and Destiny of the Colored People of the United States (1852) and Principia of Ethnology (1879) to Sutton Griggs’s Imperium in Imperio (1899) and W.E.B. DuBois’s “The Comet” (1920), black nationalist and utopian writings together reshaped and rendered portable the seemingly white, US nation-based agrarian ideal. Combining discourses of reproductive futurism, black nationalism, racial separatism, and agrarianism, these texts imaginatively facilitated the global dissemination of agrotopias—of racially homogeneous, independent farming communities that represented sustainable alternatives to US slavery and racial oppression.
Sustainable Sprawl
Authors: Goode Abby L.
Published: September 2023

This chapter traces Walt Whitman’s career-long development of eugenic agrarianism—a discourse that adapts US nation-based ideals of small farming to a global, industrial context. While scholars have long analyzed the social, political, and economic features of Whitman’s democratic poetics, this chapter reveals how Whitman transforms agrarianism into an explicitly racial and reproductive discourse. Influenced by the Free Soil movement and the rise of racial science in the US, especially the popularization of phrenology, Whitman uses physiological and hereditarian vocabulary to racialize the working class in his early political writings. Following this trend, Leaves of Grass (1855-1892)redefines the agrarian laborer based on physique and fertility rather than economic status alone, imagining a Jeffersonian race engaged in diverse, transnational forms of labor—farmers, loggers, and miners who harvest and distribute the fruits of a “New World” landscape. In poems such as “Song of the Redwood-Tree,” (1873), “Song of the Exposition” (1871), and “Passage to India” (1871), Whitman’s writings present a globalized version of “American sustainability”—an expansive agrotopia that emanates beyond US borders to sustain, interconnect, and ultimately, absorb the rest of the globe.
State of Disaster
Authors: Garcia Maria Cristina
Published: September 2023

Natural disasters and the dire effects of climate change cause massive population displacements and lead to some of the most intractable political and humanitarian challenges seen today. Yet, as Maria Cristina Garcia observes in this critical history of US policy on migration in the Global South, there is actually no such thing as a "climate refugee" under current US law. Most initiatives intended to assist those who must migrate are flawed and ineffective from inception because they are derived from outmoded policies. In a world of climate change, US refugee policy simply does not work.Garcia focuses on Central America and the Caribbean, where natural disasters have repeatedly worsened poverty, inequality, and domestic and international political tensions. She explains that the creation of better US policy for those escaping disasters is severely limited by the 1980 Refugee Act, which continues to be applied almost exclusively for reasons of persecution directly related to politics, race, religion, and identity. Garcia contends that the United States must transform its outdated migration policies to address today's realities. Climate change and natural disasters are here to stay, and much of the human devastation left in their wake is essentially a policy choice.
Disaster Relief as Foreign Policy
Authors: Garcia Maria Cristina
Published: September 2023

This chapter explores how US foreign policy interests have shaped responses to disasters and disaster-driven migration in Central America, focusing in particular on Hurricane Mitch’s impacts on Honduras and Nicaragua in 1998. In the aftermath of Mitch, the United States invested billions in rescue and relief operations not just out of humanitarian concern but because aid and reconstruction protected the fragile peace secured in the early 1990s, after decades of wars in the region. The US foreign assistance package for Central America involved offering Temporary Protected Status (TPS) to tens of thousands of Hondurans and Nicaraguans who were already living in the United States at the time of the disaster, many of them in the country without authorization and facing deportation. Over the next two decades, the federal government repeatedly extended TPS for Hondurans and Nicaraguans, but despite their long presence in—and ties to—the United States, many have not found a pathway to citizenship. In the two decades following Mitch, economic development policies designed to assist Central America’s recovery have also produced slower-onset disasters that have reinvigorated migration rather than stemmed it.
The effect of giving combination boiled chicken egg and red dragon fruit (Hylocereus polyrhizus) to increase hemoglobin levels in women during menstruation
Authors: Khuzaimah Ummi , Sulistiarini Riski , Rija’i Hifdzur Rashif , Alfiani Rinda
Published: September 2023

Background: Menstruation women are susceptible to anemia, due to loss of blood during this period. One alternative to prevent the occurrence of iron deficiency anemia is to consume food that contains iron and vitamin C such as egg chicken and red dragón fruit. Aims: To investigate the effect of the combined consumption of boiled chicken egg and dragon fruits to increase hemoglobin levels in women during their menstruation. Subjects and Methods: Thirty-two women (18 – 22 years) were randomized into two groups: 16 received boiled chicken eggs, 36 g/day, red dragón fruits, 365 g/day, and 16 were considered as controls. Hemoglobin level data were obtained at baseline (T0), 3 days (T1), and 5 days (T2) after the start of the treatment. Results: Results report a change in hemoglobin levels in the intervention group compared to the control. An increase (p < 0.05) in level hemoglobin was recorded at T2. Meanwhile a decrease in hemoglobin levels in the control (p < 0.05) who does not have any treatment. Conclusions: The intervention of boiled chicken eggs and red dragons fruit increase hemoglobin levels in women and may lead to decreased iron deficiency anemia during menstruation.

Keywords: chicken egg, red dragon fruit, iron, vitamin C, menstruation, hemoglobin level.
Impact of assimilating NOAA VIIRS aerosol optical depth (AOD) observations on global AOD analysis from the Copernicus Atmosphere Monitoring Service (CAMS)

Published: September 2023

Abstract. Global monitoring of aerosols is required to analyse the impacts of aerosols on air quality and to understand their role in modulating the climate variability. The Copernicus Atmosphere Monitoring Service (CAMS) provides near-real-time forecasts and reanalyses of aerosols using the ECMWF Integrated Forecasting System (IFS), constrained by the assimilation of MODIS and Polar Multi-Sensor Aerosol Optical Properties (PMAp) aerosol optical depth (AOD). Given the potential
end of lifetime of MODIS AOD, implementing new AOD observations in the CAMS operational suite is a priority to ensure the continuity of the CAMS
forecast performances. The objective of this work is to test the assimilation of the NOAA VIIRS AOD product from S-NPP and NOAA20 satellites in the
IFS model. Simulation experiments assimilating VIIRS on top or in place of MODIS were carried out from June 2021 to November 2021 to evaluate the
impacts on the AOD analysis. For maritime aerosol background, the assimilation of VIIRS and the use of VIIRS from NOAA20 as an anchor reduce the analysis AOD values compared to
MODIS-based experiments, in which the analysis values were too high due to the positive bias of MODIS/Terra over ocean. Over land, the assimilation
of VIIRS induces a large increase in the analysis over biomass burning regions where VIIRS shows larger AOD than MODIS due to differences in the
aerosol models and cloud filtering between MODIS and VIIRS retrieval algorithms. For dust source regions, the analysis is reduced when VIIRS is
assimilated on top of or in place of MODIS, particularly over the Sahara, the Arabian Peninsula and a few places in Asia in the July–August period. The
assimilation of VIIRS leads to an overall reduction of the bias in AOD analysis evaluated against AERONET measurements, with the largest bias
reduction over Europe and desert and maritime sites.

Abstract. Root zone soil moisture (RZSM) is critical for water resource management, drought monitoring and sub-seasonal flood climate prediction. RZSM is not directly observable from space, but several RZSM products are available and widely used at global and continental scales. This paper presents a comprehensive quantitative evaluation of eight RZSM products over the Huai River Basin (HRB) in China. A direct validation is performed using observations from 58 in situ soil moisture stations from 1 April 2015 to 31 March 2020. Attention is drawn to the potential factors that increase the uncertainties of model-based RZSM, such as errors in atmospheric forcing (precipitation, air temperature), soil properties, and spatial scale mismatch. The results show that the Global Land Data Assimilation System Catchment Land Surface Model (GLDAS_CLSM) performs best among all RZSM products with the highest correlation coefficient (R) and the lowest unbiased root mean square error (ubRMSE): 0.69 and 0.018 m3 m−3, respectively. All RZSM products tend to overestimate in situ soil moisture values, except for the Soil Moisture and Ocean Salinity (SMOS) L4 product, which underestimates RZSM. The underestimation of Surface Soil Moisture (SSM) in SMOS L3, caused by underestimated physical surface temperature and overestimated ERA interim soil moisture, triggers the underestimation of RZSM in SMOS L4. The overestimation of RZSM by the other products can be explained by the overestimation of precipitation, the frequency of precipitation events (drizzle effects) and the underestimation of air temperature. In addition, the overestimation of soil clay content and the underestimation of soil sand content in different LSMs lead to higher soil moisture values. The intercomparison of the eight RZSM products shows that MERRA-2 and SMAP L4 RZSM have the highest correlation, which can be attributed to the fact that both products use the catchment land surface model and the atmospheric forcing provided by the Goddard Earth Observing System Model, version 5 (GEOS-5), although the versions differ slightly.

Abstract. Reliable and robust monitoring tools are crucial to assess the effectiveness of land mitigation techniques (LMTs) in enhancing carbon uptake, enabling informed decision-making by policymakers. This study, addressing one of the scientific goals of the EU H2020 LANDMARC project, examines the feasibility of using satellite solar-induced fluorescence (SIF), in combination with other satellite data, as a monitoring proxy to evaluate the effects of LMTs on carbon uptake. Two distinct cases are explored: (1) instantaneous vegetation destruction caused by a 2019 Eucalyptus wildfire in south-east Australia, and, (2) gradual forest gain resulting from reforestation efforts in northern China over 2007–2012. The cases are monitored using TROPOMI and GOME-2A SIF, respectively. Comparing the temporal variability in SIF across the affected and nearby reference areas reveals that vegetation dynamics changed as a consequence of the land use changes in both cases. Specifically, in the Australia case, TROPOMI demonstrated an immediate reduction in SIF signal of 0.6 mW m−2 sr−1 nm−1 (−72 %) over the Eucalypt Forest right after the fire. Exploiting the strong correspondence between TROPOMI SIF and gross primary productivity (GPP) at the nearby eddy-covariance Tumbarumba site and through the FluxSat product, we estimate that the fire led to a loss in GPP of 130–200 GgC in the first eight months after the fire. Over the northern Chinese provinces of Gansu, Shaanxi, Sichuan, Chongqing and Shanxi, we report an increase in GOME-2A summertime SIF of 0.1–0.2 mW m−2 sr−1 nm−1 coinciding with reforestation efforts between 2007 and 2012. This increase in SIF signal is likely driven by a combination of increasingly favourable natural conditions and the reforestation effort itself. A multivariate model that takes into account growth factors such as water availability and maximum temperature as well as satellite-derived forest cover data explains the observed variability in GOME-2A SIF in the Chinese case reasonably well (R2=0.72). The model suggests that both increases in forest cover as well as in soil moisture have led, in step, to the observed increase in vegetation activity over northern China. In that region, for every 100 km2 of additional forest cover, SIF increases by 0.1 mW m−2 sr−1 nm−1 between 2007 and 2012. Our study highlights that the combined use of satellite-based SIF, together with supporting in situ, modelled and satellite-data, allows to monitor the impact of LMT implementation on regional carbon uptake as long as the scale of the LMT is of sufficient spatial extent.

Abstract. The main goal of the TRacking Aerosol Convection interactions ExpeRiment (TRACER) project was to further understand the role that regional circulations and aerosol loading play in the convective cloud life cycle across the greater Houston, Texas area. To accomplish this goal, the United States Department of Energy and research partners collaborated to deploy atmospheric observing systems across the region. Cloud and precipitation radars, radiosondes, and air quality sensors captured atmospheric and cloud characteristics. A dense lower atmospheric dataset was developed using ground-based remote sensors, a tethersonde, and uncrewed aerial systems (UAS). TRACER-UAS is a subproject that deployed two UAS platforms to gather high-resolution observations in the lower atmosphere between 1 June and 30 September 2022. The University of Oklahoma CopterSonde and the University of Colorado Boulder RAAVEN (Robust Autonomous Aerial Vehicle – Endurant Nimble) were flown at two coastal locations between the Gulf of Mexico and Houston. The University of Colorado RAAVEN gathered measurements of atmospheric thermodynamic state, winds and turbulence, and aerosol size distribution. Meanwhile, the University of Oklahoma CopterSonde system operated on a regular basis to resolve the vertical structure of the thermodynamic and kinematic state. Together, a complementary dataset of over 200 flight hours across 61 days was generated, and data from each platform proved to be in strong agreement. In this paper, the platforms and respective data collection and processing are described. The dataset described herein provides information on boundary layer evolution, the sea breeze circulation, conditions prior to and nearby deep convection, and the vertical structure and evolution of aerosols.
Forced and internal components of observed Arctic sea-ice changes

Published: September 2023

Abstract. The Arctic sea-ice cover is strongly influenced by internal variability on decadal timescales, affecting both short-term trends and the timing of the first ice-free summer. Several mechanisms of variability have been proposed, but how these mechanisms manifest both spatially and temporally remains unclear. The relative contribution of internal variability to observed Arctic sea-ice changes also remains poorly quantified. Here, we use a novel technique called low-frequency component analysis to identify the dominant patterns of winter and summer decadal Arctic sea-ice variability in the satellite record. The identified patterns account for most of the observed regional sea-ice variability and trends, and they thus help to disentangle the role of forced and internal sea-ice changes over the satellite record. In particular, we identify a mode of decadal ocean–atmosphere–sea-ice variability, characterized by an anomalous atmospheric circulation over the central Arctic, that accounts for approximately 30 % of the accelerated decline in pan-Arctic summer sea-ice area between 2000 and 2012 but accounts for at most 10 % of the decline since 1979. For winter sea ice, we find that internal variability has dominated decadal trends in the Bering Sea but has contributed less to trends in the Barents and Kara seas. These results, which detail the first purely observation-based estimate of the contribution of internal variability to Arctic sea-ice trends, suggest a lower estimate of the contribution from internal variability than most model-based assessments.
Teachers’ Perception Towards Implementation of Principles of Universal Design for Learning (UDL) in Teaching Students with Learning Difficulties
Authors: Melhem Tareq , Al-Rashid Wijdan
Published: September 2023

This study aims to assess teachers' implementation of the principles of Universal Design for Learning (UDL) when teaching students with learning difficulties and the barriers they face in its implementation. The descriptive survey approach to describe participants' experiences using the UDL framework, a survey was conducted on 78 study participants, all teachers with learning difficulties. The questionnaire was created with 36 questions on UDL concepts using the four domains of 1) engagement, 2) representation, 3) action and expression, and 4) barriers to applying UDL. The study's findings supported that UDL implementation levels were generally high. The results also indicate that the most central principle of UDL was the representation domain, ranking first, while the action, expression, and engagement domains ranked second and third, respectively. Furthermore, the barriers that prevent teachers from implementing UDL principles in teaching were found within the intermediate level. Lastly, we recommend that professional development programs be conducted before or in service to increase teachers' knowledge of the UDL principles. Educational institutions should also overcome all barriers by creating an educational environment that supports teachers of students with learning difficulties by implementing the principles of UDL in teaching.

Published: September 2023

Background: Colorectal robotic-assisted-surgery (RAS) is a novel technology with scarce real-world evidence. The aim of this retrospective review was to ascertain the safety and effectiveness of colorectal RAS. Methods: The da Vinci® Xi™ robot system (Intuitive Surgical, Inc., Sunnyvale, CA, USA) was used to perform the first 50 colorectal resections in our centre. Outcomes regarding safety and efficacy were analysed and learning curves (LC) were plotted using RStudio. Results: The median patient age and BMI were 65 years (IQR, 50.25-76.5) and 28.3kg/m2 (IQR, 25.2-30.7), respectively, and 27 patients were female. Malignancy (66%) followed by rectal prolapse (18%) was the most frequent diagnosis, and all malignant tumours were completely resected. High anterior resection was the most frequently performed operation (36%). The median operative time was 256.5 minutes (IQR, 202.2-332.8). Twenty-seven patients had anastomosis (54%), a stoma was formed in 7 (14%) and 7 anastomoses required defunctioning loop ileostomy (14%). Two unexpected intra-operative events occurred, and neither required conversion to an open procedure. Thirty-eight complications occurred in 21 patients, and most were minor by the Clavien-Dindo classification: CD 1 (17, 44.7%) or 2 (11, 28.9%). Moreover, 5 patients developed an anastomotic leak (14.7%), 5 developed infections (10%), 2 required transfusions (4%) and 3 needed re-operation (6%). There was no 30-day mortality and the readmission rate was 8%. The median length of stay in hospital was 6 days (IQR,4-8). All resections, except for low anterior resections, resulted in a significantly longer stay compared to rectopexies. Finally, projections from LCs indicated that outcome optimization can be achieved after experience with 33-39 cases. Conclusions: Colorectal RAS in our centre was both safe and effective. In the initial 50 cases, there was no 30-day mortality and no need for conversion to an open surgery. The readmission and complication (>CD 2) rates were 8% and 20%, respectively.
Acellular Fish Skin Graft Use in Open Abdomen Management
Authors:   College of Medicine, University of Arizona, Tucson, Arizona, Latifi Rifat , Smiley Abbas ,   Department of Preventive Medicine, School of Medicine, University of Rochester, Rochester, New York
Published: September 2023

Introduction: Open abdomen (OA) management post damage control laparotomy (DCL) is common in complex abdominal trauma and intra-abdominal catastrophe (IAC). Use of polyglactin 910 mesh (VICRYL™, Johnson & Johnson, New Brunswick, New Jersey) to cover the intra-abdominal contents and wound vacuum-assisted closure (VAC) is current practice in the management of temporary abdominal closure (TAC). This may have complications and requires two to three weeks for granulations to be ready for skin grafting. Acellular fish skin graft (AFSG; Kerecis™, Reykjavik, Iceland), use in wound care management has proven beneficial in the management of both chronic and acute wounds, such as burns, by increasing wound granulation. However, to our knowledge, its utility in OA management has not been reported. Objective: The objective of this report is to introduce a novel use of AFSG (Kerecis™) in open abdomen to decrease the time of TACs by accelerating formation of granulation tissue and placement of skin grafts in patients with post damage control laparotomy (DCL) for trauma and IAC when committed to open abdomen management is presented. Materials and Methods: Illustration of application of AFSG (Kerecis™) in two patients who underwent DCL for IAC and OA management is presented. Results: Two patients with intra-abdominal catastrophe post-DCL and fistulae were enrolled; one with postoperative enteric fistula and the other with post-anastomotic ileo-colonic fistula breakdown and major intra-abdominal sepsis resulting in multiple organ system failure (MOSF). In both cases, a hostile abdomen was present. The application of AFSG accelerated the placement of skin grafts in both patients and decreased the use of wound VAC and hospital length of stay. Conclusion: This report illustrates the use of AFSG (Kerecis™) to accelerate placement of skin grafts in patients post-DCL and OA management. AFSG (Kerecis™) could be considered as part of the OA management strategy.

Introduction: The use of robotic-arm assistance for medial unicompartmental knee arthroplasty (RAUKA) has become an area of interest to overcome technical challenges, improve accuracy, and optimize patient outcomes. Due to the rise in osteoarthritis (OA) and robotic assistance, well-powered long-term studies are warranted. The aim of this study was to analyze midterm survivorship, radiographic changes, range of motion (ROM), and patient-reported outcome measurements (PROMs) of RAUKA. Materials and Methods: Patients who underwent RAUKA for medial compartmental OA were identified from April 2009 to May 2014. The query yielded 162 knees with a mean follow up of 6.5 years. Primary endpoints were to compare survivorship, final mechanical axis alignment, radiographic changes, mean ROM, and changes to the following PROMs: Knee Society Score (KSS), International Knee Documentation Committee (IKDC), and Oxford Knee Score (OKS). Statistical analyses were primarily descriptive. A p-value less than 0.05 was considered statistically significant. Results: There were no revisions of the primary implant, one case required exchange of polyethylene bearing and debridement for deep infection, and five cases required additional surgical intervention with implant retention. Overall survivorship was 100%. Radiographic assessment demonstrated no mechanical loosening or osteolysis surrounding the implant. Mean ROM was 3 to 121.9º. Patients demonstrated a mean functional KSS of 78.55, IKDC of 78.22, and OKS of 43.94. Conclusions: The study supports excellent mid-term outcomes in patients undergoing RAUKA for medial compartment OA. Longer term follow-up studies are necessary to determine the efficacy of this technology for patients undergoing RAUKA for medial compartment OA.
Robotic-Arm Assisted Lateral Unicompartmental Knee Arthroplasty: Case Series with Minimum Five-Year Follow-Up

Introduction: Lateral unicompartmental knee arthroplasty has been shown to be a successful treatment modality for isolated lateral osteoarthritis (OA) of the knee. The reproduction of proper knee kinematics, limb alignment, as well as proper soft tissue balancing and component positioning have been shown to be of the utmost importance for a successful unicompartmental knee arthroplasty (UKA). Robotic assistance has shown to be a reliable tool in order to replicate these factors, as compared to manual instrumentation alone. Recent studies have shown the potential of robotic-assisted surgery in controlling these surgical factors for medial UKA; however, studies assessing outcomes of robotic-assisted lateral UKA (RAUKA) are lacking. Therefore, a retrospective single-center study was performed to assess outcomes of lateral RAUKA. Materials and Methods: Patients who underwent lateral RAUKA from a single surgeon at a central institution between January 2008 and June 2017 were identified. All patients received a lateral UKA with a fixed-bearing metal backed onlay tibial component. Patients over the age of 18, with at least a five-year follow-up and a lateral UKA were contacted by phone and asked a series of questions to determine satisfaction and survivorship. Each patient was asked in a “yes” or “no” manner, if they have had their implant revised or reoperated for any reason, and a 5-point Likert scale was used to assess satisfaction. Results: Data was collected from 50 patients (53 knees). Of the patients that responded: 32 (60%) were right knees; 32 (60%) were female, and average follow-up was 7.6 years (5–14 years). Of the 53 knees, one had a revision (98% survivorship). Excluding the revision, 51 (98%) of the included cases were either “very satisfied” or “satisfied” with their surgery. Discussion/Conclusions: Robotic-arm assisted lateral UKA was found to have high survivorship and a satisfaction rate in patients that had at least a five-year follow-up. In the future, larger prospective comparison studies with longer follow-ups are necessary to adequately compare survivorship and satisfaction rates of robotic-assisted lateral UKA to conventional UKA.

Osteonecrosis of the femoral head is a progressive and potentially debilitating disorder that is responsive to core decompression, especially in early-stage disease. This is typically accomplished through use of an 8 to 10mm trephine or multiple, small-diameter percutaneous drilling. Use of the large diameter trephine is associated with risk of fracture and may not allow healing across large gaps. Here, we present a technique for core decompression using percutaneous drilling that allows bone marrow aspiration concentrate to be introduced. We used the aspirate needle to decompress the femoral head osteonecrotic lesion, followed by the administration of bone marrow aspirate concentrate. This is a straightforward procedure that can be used with low risk for patient morbidity.

The utilization of robotic-arm assisted unicompartmental knee arthroplasty (UKA) or partial knee arthroplasty (PKA) for the treatment of medial unicompartmental osteoarthritis has continued to increase. This is in part due to the consistently reproducible accuracy and precision of implant planning, intra-operative ligament balancing software, tracking optimization software, robotic-arm assisted bone preparation, excellent survivorship rates, and improvements in many patient-reported outcomes compared to manual UKA, using the Stryker Mako™ Robotic Partial Knee System (Stryker, Mako Surgical Corp., Mahwah, New Jersey). Training in the utilization of robotic-arm assistance can be time-consuming and comes with an associated learning curve even after the in-person training and coursework is complete, like most procedures. Therefore, our aim was to describe the pre-operative planning and intra-operative surgical technique for using a robotic-arm assisted partial knee system for UKA/PKA in patients who have unicompartmental medial knee osteoarthritis. Specifically, we will discuss: 1) pre-operative planning; 2) operative setup; 3) intra-operative steps; 4) execution of the plan; and 5) trialing, implantation, and final assessments.

Background: Disposable NPWT (dNPWT), a form of negative-pressure wound therapy, has been shown to be both outcome- and cost-effective for small to medium-sized wounds or closed incisions compared to traditional NPWT systems. When choosing a dNPWT system, multiple factors should be evaluated, including the wound size, wound type, estimated exudate production, and required days of therapy. If the device is not optimized for use in a particular patient, a much higher overall cost can be expected. Methods: A web-based search, manufacturer website review and communication, and list price-based cost analysis was performed for currently available dNPWT systems. These systems differ with respect to cost, degree of negative pressure, canister size, number of dressings included, and recommended days of therapy. Results: The results showed that 3M™ KCI devices (3M™ KCI, St. Paul, MN) cost about 6x more per day than non-KCI devices, and the V.A.C.® Via and Prevena™ Plus Customizable Incision Management System (both 3M KCI) cost over $180 per day of use. The no-canister Pico 14™ (Smith+Nephew, Watford, UK) is the most cost-effective dNPWT option, with an overall cost of $25.00 per day, but is limited to low exudate-producing wounds, such as closed incisions. At $25.67 per day, the UNO 15 (Genadyne Biotechnologies, Hicksville, NY) is the most cost-effective dNPWT option that still includes a replaceable canister system. Conclusion: We present a cost and metric comparison of currently available dNPWT systems. Despite significant differences in the cost of treatment with each dNPWT device, there has been limited research on their relative efficacies.

This study examines how users thought about and adapted to the e-wallet. We made conceptual research by adding an attitude to see how well it might predict how users would adjust to an e-wallet. Self-efficacy (independent construct), risk attitude (mediating construct), and adaptive behavior are all independent constructs (Dependent variable). This study intends to show that self-efficacy is an important factor in figuring out risk attitudes toward user adaptive behavior. There is a strong need for research on the attitudes that motivate users to start using e-wallets so that financial providers may improve their marketing and product offers and increase demand for their products.

The aim of this study is to review the teaching practice course, conducted to prepare pre-service teachers studying in faculties of education for the teaching profession in terms of practical as well as theoretical knowledge, within the framework of different variables. The study was conducted by adopting the principles of qualitative study method. A semi-structured interview form prepared by the researchers was used to collect data required. In this regard, the study included 10 pre-service social studies teachers who taking the teaching practice course, 10 social studies teachers working in the practice schools, and 10 secondary school students studying in the practice class. Descriptive analysis and content analysis methods were used to analyze the data obtained as a result of the interviews. At the end of the study, we found that the pre-service teachers experienced feelings of excitement, happiness, pride, inadequacy, disappointment and fear during the lecturing processes. Moreover, we have revealed that the mentor teachers that they mostly considered the pre-service teachers inadequate in terms of content knowledge and pedagogical knowledge. The students is carried out find pre-service teachers adequate in terms of classroom management and lecturing, but the fact that pre-service teachers mostly use narration and question and answer methods stands out as a negative situation.
Manejo clínico de gestante com história de miocardiopatia periparto evoluindo com piora do quadro de insuficiência cardíaca no terceiro trimestre: relato de caso
Authors: Menezes Gabriela Oliveira de , Rodriguez Isabela Carmona Castro , Izzo Aline Silva
Published: September 2023

Introdução: As cardiopatias afetam cerca de 0,3 a 4% das gestações em países desenvolvidos. No Brasil, a incidência chega a 4,2% em centros de referência, sendo identificadas como as principais causas indiretas de mortalidade materna. A estenose mitral de origem reumática é a cardiopatia mais frequente no território brasileiro, enquanto nos EUA a cardiopatia congênita é a mais incidente. Quanto à miocardiopatia periparto, trata-se de uma forma de insuficiência cardíaca (IC) sistólica com redução da fração de ejeção (FE) do ventrículo esquerdo, que afeta mulheres durante a gravidez ou no período pós-parto inicial. Esse diagnóstico é de exclusão e muitos dos achados da doença podem ser compatíveis com sinais e sintomas do final da gestação e do período periparto. Isso pode explicar uma incidência real desconhecida da doença, devido a provável subdiagnóstico. A via de parto e o momento do parto devem ser avaliados em conjunto com a Cardiologia, mas, em pacientes compensadas, não é necessária a antecipação do parto. Relato de caso: M.J.S., 38 anos, multípara, com 2 partos normais e 2 partos cesáreas prévios, está atualmente com 36 semanas e 5 dias de gestação. A paciente procurou atendimento de emergência queixando-se de edema de membros inferiores e dispneia. Ela realizou pré-natal de alto risco devido à IC com FE reduzida há três anos. Relata que, no puerpério tardio da gestação anterior, foi diagnosticada com miocardiopatia periparto. Durante esta gestação, ela fez uso de ácido acetilsalicílico (AAS), furosemida e bisoprolol. No ecocardiograma transtorácico (ECOTT) realizado 2 meses antes da consulta atual, a paciente apresentava uma FE de 47%, disfunção sistólica global leve do ventrículo esquerdo e hipocinesia difusa. Após a avaliação do exame físico, a paciente foi internada para vigilância clínica e foi realizado um novo ECOTT, que demonstrou agravamento da doença de base com refluxo mitral grave. Durante a internação, houve uma piora progressiva dos sintomas de congestão, apesar do aumento das doses da medicação diurética e do beta bloqueador. Após discussão conjunta com a Cardiologia, indicou-se a realização de cesariana a termo, com 38 semanas. O puerpério transcorreu fisiologicamente, com observação intensiva na Unidade Coronariana. A paciente apresentou melhora da queixa de dispneia e edema de membros inferiores após o parto e segue sob os cuidados da Cardiologia em acompanhamento ambulatorial. Comentário: A miocardiopatia periparto é um importante diagnóstico a ser considerado na avaliação de pacientes grávidas. No caso relatado, é possível observar a importância do acompanhamento multidisciplinar e individualizado da paciente cardiopata. Mulheres compensadas durante a gestação podem apresentar uma piora do quadro clínico da patologia de base, principalmente durante o terceiro trimestre.
