Network analysis of spread of SARS-CoV-2 within dialysis clinics: A multi-center network analysis
Authors: Duan Sunpeng , Wang Yuedong , Kotanko Peter , Zhang Hanjie 
Published: March 2024

Background
In-center hemodialysis entails repeated interactions between patients and clinic staff, potentially facilitating the spread of COVID-19. We examined if in-center hemodialysis is associated with the spread of SARS-CoV-2 between patients.

Methods
Our retrospective analysis comprised all patients receiving hemodialysis in four New York City clinics between March 12th, 2020, and August 31st, 2022. Treatment-level clinic ID, dialysis shift, dialysis machine station, and date of COVID-19 diagnosis by RT-PCR were documented. To estimate the donor-to-potential recipient exposure (“donor” being the COVID-19 positive patient denoted as “COV-Pos”; “potential recipient” being other susceptible patients in the same shift), we obtained the spatial coordinates of each dialysis station, calculated the Euclidean distances between stations and weighted the exposure by proximity between them. For each donor, we estimated the donor-to-potential recipient exposure of all potential recipients dialyzed in the same shift and accumulated the exposure over time within the ‘COV-Pos infectious period’ as cumulative exposures. The ‘COV-Pos infectious period’ started 5 days before COVID-19 diagnosis date. We deployed network analysis to assess these interactions and summarized the donor-to-potential recipient exposure in 193 network diagrams. We fitted mixed effects logistic regression models to test whether more donor-to-potential recipient exposure conferred a higher risk of SARS-CoV-2 infection.

Results
Out of 978 patients, 193 (19.7%) tested positive for COVID-19 and had contact with other patients during the COV-Pos infectious period. Network diagrams showed no evidence that more exposed patients would have had a higher chance of infection. This finding was corroborated by logistic mixed effect regression (donor-to-potential recipient exposure OR: 0.63; 95% CI 0.32 to 1.17, p = 0.163). Separate analyses according to vaccination led to materially identical results.

Conclusions
Transmission of SARS-CoV-2 between in-center hemodialysis patients is unlikely. This finding supports the effectiveness of non-pharmaceutical interventions, such as universal masking and other procedures to control spread of COVID-19.

Introduction
Implant infections caused by Staphylococcus aureus are responsible for high mortality and morbidity worldwide. Treatment of these infections can be difficult especially when bacterial biofilms are involved. In this study we investigate the potential of infrared photoimmunotherapy to eradicate staphylococcal infection in a mouse model.

Methods
A monoclonal antibody that targets Wall Teichoic Acid surface components of both S. aureus and its biofilm (4497-IgG1) was conjugated to a photosensitizer (IRDye700DX) and used as photoimmunotherapy in vitro and in vivo in mice with a subcutaneous implant pre-colonized with biofilm of Staphylococcus aureus. A dose of 400 μg and 200 μg of antibody-photosensitizer conjugate 4497-IgG–IRDye700DXwas administered intravenously to two groups of 5 mice. In addition, multiple control groups (vancomycin treated, unconjugated IRDye700DX and IRDye700DX conjugated to a non-specific antibody) were used to verify anti-microbial effects.

Results
In vitro results of 4497-IgG-IRDye700DX on pre-colonized (biofilm) implants showed significant (p<0.01) colony-forming units (CFU) reduction at a concentration of 5 μg of the antibody-photosensitizer conjugate. In vivo, treatment with 4497-IgG-IRDye700DX showed no significant CFU reduction at the implant infection. However, tissue around the implant did show a significant CFU reduction with 400 μg 4497-IgG-IRDye700DX compared to control groups (p = 0.037).

Conclusion
This study demonstrated the antimicrobial potential of photoimmunotherapy for selectively eliminating S. aureus in vivo. However, using a solid implant instead of a catheter could result in an increased bactericidal effect of 4497-IgG-IRDye700DX and administration locally around an implant (per operative) could become valuable applications in patients that are difficult to treat with conventional methods. We conclude that photoimmunotherapy could be a potential additional therapy in the treatment of implant related infections, but requires further improvement.

Authors: Narváez Rivas Ana María , Gómez Ramírez Briana Davahiva 
Published: March 2024

Introducción. El vegetarianismo tiene como eje central la exclusión de alimentos de origen animal. No obstante, dichos cambios en el patrón alimentario conllevan retos sociales porque la adquisición y consumo de alimentos dependen de diversos factores. Dado lo anterior, el objetivo de este estudio fue identificar las estrategias de la elección de alimentos para el consumo dentro y fuera del hogar que tienen algunas familias vegetarianas del Valle de Aburrá, Colombia.
Metodología. Se realizó estudio cualitativo fenomenológico con 16 familias vegetarianas captadas por muestreo de poblaciones ocultas y técnica de bola de nieve. Mediante una entrevista semiestructurada se indagó sobre el consumo fuera de casa y la elección de alimentos para el consumo diario.
Resultados. En las elecciones alimentarias para el consumo dentro y fuera del hogar, las familias prefieren alimentos naturales o con un menor grado de procesamiento y que a su vez no contengan nutrientes trazadores de riesgo en salud, por lo que puede tratarse de una alimentación con mayor conciencia. En esta misma línea, optan por elegir establecimientos con denominación vegetariana, sin embargo, los participantes refieren que en ocasiones hay dificultades en el acceso en ambientes escolares.
Conclusión. En la actualidad, se está buscando fomentar consumos alimentarios saludables y responsables. Las estrategias aquí expuestas se muestran como alternativas viables ante las problemáticas de salud y del medioambiente.
Effect of waste tire products on some characteristics of roller-compacted concrete
Authors: Abed Ziyad Majeed , Khalil Wasan Ismail , Ahmed Hisham Khalid 
Published: March 2024

Abstract
Roller-compacted concrete pavement (RCCP) is one of the most durable, economical, and practical solutions for the construction of roads for various heavy-duty purposes. To make RCCP more sustainable, different waste materials have been utilized. These materials were densified silica fume (SF), ground granulated blast furnace slag (S), crumb rubber (CR), and recycled steel fibers (RSFs) from waste tires. The weight percentages of replacement for SF and S from cement were 5, and 27.5%, respectively. CR was utilized as a volumetric replacement of sand with 0, 2, 5, and 10%. As a volumetric addition of concrete, RSF with 0.2, 0.4, and 0.6% was utilized. Water content was 6% for all mixtures. The impact resistance test was performed to evaluate the behavior of RCCP to the repeated load on roads. Also, ultrasonic pulse velocity (UPV) (nondestructive) and abrasion resistance tests were performed to validate roller-compacted concrete (RCC) as pavement. There is a substantial increase in impact energy by using 10% of CR and 0.6% of RSF, compared with that of reference specimens. The use of CR and RSF can improve the abrasion resistance of RCC, and this can ensure its applications in pavements. The relationships between impact, abrasion, and UPV were established, and models have been proposed to predict these relationships.

Published: March 2024

Abstract
This study combines two types of waste materials to achieve sustainable lightweight concrete (LWC) including agricultural and industrial wastes that hold high potential to reduce global environmental pollution. A novel application of 35% treated date seed (DS) wastes as partially replaced by volume to natural coarse aggregate in producing sustainable LWC was investigated. Calcium hydroxide solution was utilized as a treatment to extract cellulose from the achieved hemicelluloses of the DS. Fourier transform infrared spectroscopy was utilized to analyze the structural characteristics of the isolated cellulosic samples before and after treatment. Then different volume fractions of steel fibers (0.5, 0.75, and 1%) recycled from scrap tires were added to the LWC with 35% DS. Several experimental tests, including slump test, compressive strength, oven-dry density, split tensile strength, flexural strength, and water penetration depth, were carried out in this investigation. The results demonstrate that concrete containing 35% DS and reinforced with 1% recycled steel fibers show enhancement in the compressive, tensile, and flexural strengths by about 15.2, 32.6, and 58.2%, respectively, and reduces the permeability by 16.1% relative to the reference concrete mixture.

Abstract
The water-cement ratio is multiple phases procedure in which we aim to determine the most optimal combination for producing high-performing concrete. In modern literature and business practice, there are various methods for designing concrete mixes, although the Three Equation Method-inspired procedures are by far the most widely used. Concrete compressive strength is one of the fundamental properties that determines its class. Foreseeable compressive strength concrete is necessary to promote the use of concrete structures. The primary feature of its durability and safety is. Deep learning has recently received a lot of attention, and the prospects for this technology are even brighter. Machine learning algorithms have advanced to the point that they can recognize patterns, which are difficult for humans to recognize. This has sparked interest in data mining on enormous datasets. In this research, we aim to utilize cutting-edge developments in machine learning techniques for the production of concrete mixes. To provide the ideal structure of a synthetic neural network that has been chosen, we compiled a comprehensive dataset of concrete mixtures, complete with laboratory destructive test results. A mathematical formula that may be used in practical applications has been developed from the creation of an artificial neural network.

Authors: Mohapatra Aswini Kumar , R Aswathy N 
Published: March 2024

Abstract
This research focuses on the preparation of poly (3-hydroxy butyrate) (PHB) nanocomposites using the melt mixing method. Two types of organically modified nanoclay, Cloisite 93A (C93A), and Cloisite 30B (C30B), were incorporated at various weight percentages into the PHB matrix to create the nanocomposites. Comparative analyses were conducted between PHB/C93A and PHB/C30B to assess their tensile and impact properties in relation to the matrix polymer. Between the nanocomposites, the PHB/C93A nanocomposites shows an optimum tensile modulus of 949 Mpa with a 3 wt% clay loading, while PHB/C30B nanocomposites demonstrated improved percentage elongation at break of 5.33 % and enhanced Izod impact strength of 39.67 J/m at 3 wt% of clay load. The thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) signifies the thermal behavior of both the matrix and nanocomposite. The degree of crystallinity is observed to be 47 % in case of the PHB/C30B nanocomposites as compared to the PHB/C93A nanocomposites as 38 %. Again in case of thermogravimetric analysis (TGA), the maximum % char of 5.198 is observed for the PHB/C30B nanocomposites. The enhanced viscoelastic behavior of the PHB/C93A nanocomposites was attributed at a peak of approx. 55–60 °C due to the incorporation of C93A nanoclay into the matrix in the study of dynamic mechanical analysis (DMA). The morphological investigation using WAXD analysis showcased particle clay intercalation and dispersion within the PHB matrix, indicating effective clay-matrix interactions. Overall, this study sheds light on the enhanced properties of PHB nanocomposites with the incorporation of organoclay, offering potential applications in various industries.
