After screening over 2,500 documents using Scopus and Google Scholar, six relevant LCA articles of biosurfactants could be identified. The identified articles are divided into LCA studies of alkyl polyglycosides, chemically produced bio-based surfactants, and LCA studies of microbial biosurfactants, their content analyzed and discussed in context. In conclusion, the number of available LCA studies is very limited and their results are often not comparable. To the best of the authors' knowledge, this review is the first of its kind to provide a detailed overview of LCA studies of biosurfactants. Consequently, the need for implementing more LCA studies becomes clear.

Total body irradiation (TBI) is acommon part of the myelo- and immuno-ablative conditioning regimen prior to an allogeneic hematopoietic stem cell transplantation (allo-HSCT). Due to concerns regarding acute and long-term complications, there is currently adecline in otherwise successfully established TBI-based conditioning regimens. Here we present an analysis of patient and treatment data with focus on survival and long-term toxicity.

Patients with hematologic diseases who received TBI as part of their conditioning regimen prior to allo-HSCT at Frankfurt University Hospital between 1997 and 2015 were identified and retrospectively analyzed.

In all, 285 patients with amedian age of 45years were identified. Median radiotherapy dose applied was 10.5 Gy. Overall survival at1, 2, 5, and 10years was 72.6, 64.6, 54.4, and 51.6%, respectively. Median follow-up of patients alive was 102 months. The cumulative incidence of secondary malignancies was 12.3% (n = 35), with hematologic malignancies and skin cancer appear to be subject to substantial confounding in this context.

To identify the changes of school burnout for Finnish adolescents in lower (grades 8-9) and upper secondary schools (grades 10-11) during years 2006-2019; and to examine the associations of personal-(gender, family socioeconomic, and immigrant status) and school-related (school level, urban-rural area) sociodemographic demands and resources in school burnout.

We used nationally representative data on 949,347 students in secondary school in Finland between 2006 and 2019. Generalized Linear Models were used to assess the effects of year, gender, school level, parental education, unemployment, immigrant status, and urban-rural area and the interactions of year, gender, and school level with each of the remaining sociodemographic variables on school burnout.

School burnout increased among girls and slightly declined among boys. The increase intensified in girls and the decline in boys stagnated after 2011. The educational level of the parents had a constant protective impact over time, the gradient for boysgration, especially when concurring with lower parental education.

Length of stay (LOS) and readmissions are quality metrics linked to physician payments and substantially impact the cost of care. This study aims to evaluate the effect of documented and undocumented psychiatric conditions on LOS, discharge location, and readmission following total knee arthroplasty (TKA).

Retrospective review of all primary, unilateral TKA from 2015 to 2020 at a high-volume, academic orthopedic hospital was conducted. Patients were separated into three cohorts patients with a documented psychiatric diagnosis (+Dx), patients without a documented psychiatric diagnosis but with an actively prescribed psychiatric medication (-Dx), and patients without a psychiatric diagnosis or medication (control). Patient demographics, LOS, discharge location, and 90days readmissions were assessed.

A total of 2935 patients were included; 1051 patients had no recorded psychiatric medications (control); 1884 patients took at least one psychiatric medication, of which 1161 (61.6%) were in the-Dx and 723 (38cumented psychiatric diagnoses when constructing metrics. Surgeons and institutions should also direct their attention to identifying, recording, and managing these patients to improve outcomes.

Retrospective Cohort Study.

Retrospective Cohort Study.

This study compares orthopedic injuries, procedures, and hospital outcomes of patients presenting to trauma centers in Pennsylvania before and during the COVID-19 pandemic.

A retrospective review of adult patients presenting to hospitals with Pennsylvania Trauma Systems Foundation (PTSF) designations was performed. All patients 18years of age and older who presented with orthopedic injuries were included. Demographic information, injury and hospital stay details, and mortality were reviewed. Data were compared between the cohorts of patients presenting during April 2020 (COVID cohort) and April 2017, April 2018, and April 2019 (pre-COVID cohort).

Overall, 14,858 patients were reviewed, and 9427 patients were included in this study. There were fewer orthopedic injuries (4868 vs. 6603 yearly mean) in the COVID cohort which led to fewer procedures (1763 vs. 2329 yearly mean). The COVID cohort had a significantly shorter mean hospital length of stay compared to the pre-COVID cohort (4.7days versus 5.2days, p = 0.01). A higher mortality rate was seen in the COVID cohort (n = 115, 6.1%) compared to the pre-COVID cohort (n = 305, 4.0%; p < 0.01).

The characteristics of orthopedic injuries sustained by patients presenting to trauma centers during the COVID pandemic were not different from prior to the pandemic. However, there were decreases in the number of orthopedic injuries and procedures accompanied by a 50% increase in mortality seen in these patients during the pandemic. Resources should be appropriately marshalled to prevent rises in-hospital mortality for patients with orthopedic trauma treated during a pandemic.

We implemented a COVID-19 vaccination initiative for justice-involved youth residing at the county juvenile detention center and enrolled in local community-based monitoring programs. Our overarching goal was to increase COVID-19 vaccine access and uptake for justice-involved youth in Allegheny County, Pennsylvania. Our efforts incorporated a virtual forum with youth, guardians, and community partners; one-on-one outreach to guardians; motivational interviewing with youth; and coordination with organizational leaders. We collaborated with a multidisciplinary medical team to offer individualized education and counseling to parents and youth expressing vaccine hesitancy. We developed a logistical framework to ensure complete COVID-19 vaccination series for all youth, including centralized tracking and implementation of multiple community-based vaccine clinics. Through our initiative, 31 justice-involved youth have received at least 1 dose of the Pfizer-BioNTech COVID-19 vaccine. A total of 50 doses have been administered as a result of this initiative. This work has reaffirmed hypothesized barriers to vaccine access among justice-involved youth, including limited parental involvement, inadequate transportation, vaccine misinformation, and distrust rooted in histories of medical mistreatment of communities of color. Best practices for promoting equitable vaccination efforts among vulnerable subgroups include partnering closely with diverse community members; offering individualized, strengths-based counseling on vaccine safety, efficacy, and importance; and demonstrating provider trustworthiness by recognizing histories of oppression.A manual material handling task involves the phases of reaching, lifting, unloading, and standing up (RLUS). Understanding the mechanisms of manual material handling is important for occupational health and the development of assist devices. Predictive models are becoming popular in exploring which performance criterion is appropriate in the lifting phase. However, limited attempts have been performed on the other phases. The associated performance criterion for predicting other phases is unknown. In this study, an optimization model for predicting RLUS has been developed with the multi-objective optimization method. Two performance criteria (minimum dynamic effort and maximum balance) were studied to explore their importance in each phase. The result shows that maximum balance leads to joint angle errors 27.6% and 40.9% smaller than minimum dynamic effort in reaching and unloading phases, but 40.4% and 65.9% larger in lifting and standing up phases. When the two performance criteria are combined, the maximum balance could help improve the predicting accuracy in the reaching, lifting, and unloading phases. These findings suggest that people prefer different performance criteria in different phases. This study helps understand the differences in motion strategies in manual materials handling (MMH), which would be used to develop a more accurate predictive model.Tissue-based transcatheter aortic valve (AV) replacement (TAVR) devices have been a breakthrough approach for treating aortic valve stenosis. However, with the expansion of TAVR to younger and lower risk patients, issues of long-term durability and thrombosis persist. Metabolism inhibitor Recent advances in polymeric valve technology facilitate designing more durable valves with minimal in vivo adverse reactions. We introduce our second-generation polymeric transcatheter aortic valve (TAV) device, designed and optimized to address these issues. We present the optimization process of the device, wherein each aspect of device deployment and functionality was optimized for performance, including unique considerations of polymeric technologies for reducing the volume of the polymer material for lower crimped delivery profiles. The stent frame was optimized to generate larger radial forces with lower material volumes, securing robust deployment and anchoring. The leaflet shape, combined with varying leaflets thickness, was optimized for reducing the flexural cyclic stresses and the valve's hydrodynamics. Our first-generation polymeric device already demonstrated that its hydrodynamic performance meets and exceeds tissue devices for both ISO standard and patient-specific in vitro scenarios. The valve already reached 900 × 106 cycles of accelerated durability testing, equivalent to over 20 years in a patient. The optimization framework and technology led to the second generation of polymeric TAV design- currently undergoing in vitro hydrodynamic testing and following in vivo animal trials. As TAVR use is rapidly expanding, our rigorous bio-engineering optimization methodology and advanced polymer technology serve to establish polymeric TAV technology as a viable alternative to the challenges facing existing tissue-based TAV technology.We developed a rhodium-catalysed decarbonylative C(sp2)-H alkylation method for indolines. This reaction facilitates the use of alkyl carboxylic acids and their anhydrides as a cheap, abundant and non-toxic alkyl source under redox-neutral conditions, featuring the introduction of a primary alkyl chain, which cannot be addressed by previous radical-mediated decarboxylative reaction. Through a mechanistic investigation, we revealed that an initially formed C-7 acylated indoline was transformed into the corresponding alkylated indoline via a decarbonylation process.
