Cryogel wound dressings based on natural polysaccharides perfectly adhere to irregular wounds for rapid haemostasis and easy disassembly
Authors: Liu Changchun , Liu Jiaqi , Wu Minmin , Ni Haifeng , Feng Jie , Zhao Liping , Zhang Jing 
Published: March 2024

AbstractSkin injuries can have unexpected surfaces, leading to uneven wound surfaces and inadequate dressing contact with these irregular surfaces. This can decrease the dressing's haemostatic action and increase the healing period. This study recommends the use of sticky and flexible cryogel coverings to promote faster haemostasis and efficiently handle uneven skin wounds. Alginate cryogels have a fast haemostatic effect and shape flexibility due to their macroporous structure. The material demonstrates potent antibacterial characteristics and enhances skin adherence by adding grafted chitosan with gallic acid. In irregular defect wound models, cryogels can cling closely to uneven damage surfaces due to their amorphous nature. Furthermore, their macroporous structure allows for quick haemostasis by quickly absorbing blood and wound exudate. After giving the dressing a thorough rinse, its adhesive strength reduces and it is simple to remove without causing any damage to the wound. Cryogel demonstrated faster haemostasis than gauze in a wound model on a rat tail, indicating that it has considerable potential for use as a wound dressing in the biomedical area.
Information Embedding in Additively Manufactured Parts Through Printing Speed Control
Authors: ElSayed Karim A. , Panchal Jitesh H. 
Published: March 2024

Abstract
Information lithography in manufacturing is a broad set of techniques for encoding sequences of bits as physical or behavioral features in physical parts. It is an effective approach for part traceability and anti-counterfeiting. Several techniques have recently been proposed for embedding 2D codes in 3D printed parts by local control of geometry or material. This paper presents an approach to embed and retrieve information in additive manufacturing (AM) parts by controlling the printing process parameters. The approach leverages variations in printing speed to encode information on the surface of AM parts. Optical imaging devices, such as 2D scanners and optical profilometers, are employed to read the embedded information, enabling the capture of local height differences on the part surfaces that embody 2D codes such as QR codes. The retrieved information is processed using computer vision techniques such as morphological segmentation and binary classification. First, the impact of variations in the encoding parameters on the information retrieval accuracy is characterized. Then, the feasibility and effectiveness of the proposed scheme are demonstrated through experimental results, showcasing a high accuracy in retrieving encoded messages and successfully distinguishing subtle surface features resulting from varying printing speeds. The proposed approach offers an inexpensive and efficient method for information lithography, allowing for the secure embedding of information, e.g., serial numbers and watermarks, while addressing counterfeiting and security concerns in diverse industries.

Published: March 2024

Abstract
Data-driven research in additive manufacturing (AM) has gained significant success in recent years. This has led to a plethora of scientific literature emerging. The knowledge in these works consists of AM and artificial intelligence (AI) contexts that haven't been mined and formalized in an integrated way. Moreover, no tools or guidelines exist to support data-driven knowledge transfer from one context to another. As a result, data-driven solutions using specific AI techniques are being developed and validated only for specific AM process technologies. There is a potential to exploit the inherent similarities across various AM technologies and adapt the existing solutions from one process or problem to another using AI, such as transfer learning (TL). We propose a three-step knowledge transferability analysis framework in AM to support data-driven AM knowledge transfer. As a prerequisite to transferability analysis, AM knowledge is featured into identified knowledge components. The framework consists of pre-transfer, transfer, and post-transfer steps to accomplish knowledge transfer. A case study is conducted between two flagship metal AM processes: laser powder bed fusion (LPBF) and directed energy deposition (DED). The relatively mature LPBF is the source while the less developed DED is the target. We show successful transfer at different levels of the data-driven solution, including data representation, model architecture, and model parameters. The pipeline of AM knowledge transfer can be automated in the future to allow efficient cross-context or cross-process knowledge exchange.
Impact of Flow Unsteadiness on Turbine Airfoil Heat Transfer via Streaming
Authors: Agarwal Tapish , Jacobi Ian , Cukurel Beni 
Published: March 2024

Abstract
Thermal management of turbine airfoils is a critical design consideration, but the impact of unsteadiness on heat transfer of attached flow regions has received less attention in the literature. When turbine surfaces are subjected to unsteady zero-mean flow fluctuations, either naturally or artificially, the mean velocity around them is modified due to a nonlinear interaction of fluctuations, known as streaming. In this numerical study, we examine the effect of streaming on heat transfer and skin friction in a simplified model of the flow over a turbine blade. Both heat transfer and skin friction modifications were found to strongly depend on the amplitude and wave speed of the unsteady flow perturbations. Over a wide range of disturbance parameters, skin friction modification was negligible, but a significant effect on heat transfer due to streaming was identified. Moreover, the impact of favorable pressure gradients, which are typical for turbine airfoils, on the streaming phenomena was also considered, and it was found that flow regions of zero-pressure gradient produced the strongest amplification of heat transfer, although the effect of the pressure gradient varied with Strouhal number. Due to its significant effect on wall heat transfer, the streaming phenomenon should be taken into account during the design and measurement of the thermal properties of unsteady systems.
Eye infection risks from
Pseudomonas aeruginosa
via hand soap and eye drops

Published: March 2024

ABSTRACT

Eye infections from bacterial contamination of bulk-refillable liquid soap dispensers and artificial tear eye drops continue to occur, resulting in adverse health outcomes that include impaired vision or eye enucleation.
Pseudomonas aeruginosa
(
P. aeruginosa
), a common cause of eye infections, can grow in eye drop containers and refillable soap dispensers to high numbers. To assess the risk of eye infection, a quantitative microbial risk assessment for
P. aeruginosa
was conducted to predict the probability of an eye infection for two potential exposure scenarios: (i) individuals using bacteria-contaminated eye drops and (ii) contact lens wearers washing their hands with bacteria-contaminated liquid soap prior to placing the lens. The median risk of an eye infection using contaminated eye drops and hand soap for both single and multiple exposure events (per day) ranged from 10
–1
to 10
−4
, with contaminated eye drops having the greater risk. The concentration of
P. aeruginosa
was identified as the parameter contributing the greatest variance on eye infection risk; therefore, the prevalence and level of bacterial contamination of the product would have the greatest influence on health risk. Using eye drops in a single-use container or with preservatives can mitigate bacterial growth, and using non-refillable soap dispensers is recommended to reduce contamination of hand soap. Given the opportunistic nature of
P. aeruginosa
and its ability to thrive in unique environments, additional safeguards to mitigate bacterial growth and exposure are warranted.

IMPORTANCE

Pseudomonas aeruginosa
(
P. aeruginosa
) is a pathogen that can persist in a variety of unusual environments and continues to pose a significant risk for public health. This quantitative microbial risk assessment (QMRA) estimates the potential human health risks, specifically for eye infections, associated with exposure to
P. aeruginosa
in bacteria-contaminated artificial tear eye drops and hand soap. This study applies the risk assessment framework of QMRA to evaluate eye infection risks through both consumer products. The study examines the prevalence of this pathogen in eye drops and soap, as well as the critical need to implement measures that will mitigate bacterial exposure (e.g., single-use soap dispensers and eye drops with preservatives). Additionally, limitations and challenges are discussed, including the need to incorporate data regarding consumer practices, which may improve exposure assessments and health risk estimates.

Published: March 2024

IntroductionMultimodal analgesia has been associated with reduced opioid utilization, opioid-related complications, and improved recovery in various orthopedic surgeries; however, large sample size data is lacking for shoulder surgery.MethodsA retrospective review using the Premier Healthcare Database of patients who underwent inpatient or outpatient (reverse, total, partial) shoulder arthroplasty from 2010 to 2019. Opioid-only analgesia was compared with multimodal analgesia, categorized into 1, 2, or >2 additional analgesic modes, with/without a nerve block. Multivariable regression models measured associations between multimodal analgesia and opioid charges (in oral morphine equivalents (OME)), cost and length of stay, and opioid-related adverse effects (approximated by naloxone use). We report % change and 95% CIs.ResultsAmong 176 225 procedures, 169 679 (75.7% multimodal analgesia use) and 6546 (37.8% multimodal analgesia use) were inpatient and outpatient shoulder arthroplasties, respectively. Among inpatients, multimodal analgesia (>2 modes) without a nerve block (vs opioid-only analgesia) was associated with adjusted reductions in OMEs on postoperative day 1: −19.4% (95% CI −21.2% to −17.6%/representing unadjusted median OME reductions from 45 to 30 mg). For total hospitalization, this was −6.0% (95% CI −7.2% to −4.9%/representing unadjusted median OME reductions from 173 to 135 mg). Conversely, for outpatients, this was +13.7% change in OMEs (95% CI +4.4% to +23.0%/representing unadjusted median OME increases from 110 to 131 mg). In both settings, addition of a nerve block to multimodal analgesia attenuated effects in terms of opioid charges.ConclusionsMultimodal analgesia is associated with reductions in opioid charges—specifically inpatient setting—but not various other outcomes.

Published: March 2024

In the current work, the analyti cal static gravimetric technique was used to assess the solubilities of DL-α-amino butyric acid and DL-valine in an aqueous binary solvent mixture of sodium sulfate (Na2SO4) under equilibrium saturation conditions in between temperature range 288.15 and 308.15 K. Different thermodynamic factors along with transfer Gibbs energetics and entropies under standard conditions were estimated by using computational as well as theoretical method by using the experimental solubilities. Several modes of interactions that occur during solvation were also explained. The manner that solvent molecules of solute amino acids are surrounded in the aforementioned medium employed during the process is taken into consideration. Amino acids become more soluble as the temperature rises. The study also helps us to reach the conclusion that physical properties of electrolyte (Na2SO4), mixed solvent, and the size of the amino acids’ molecules are the main governing factors for the chemical stability as well as other thermodynamic and physical property like solubility of solute amino acids.

Published: March 2024

In this paper, a series of S[Formula: see text]Co4Sb[Formula: see text]Te[Formula: see text] samples were prepared by high pressure and high temperature (HPHT) method under different pressures. The synthesis time was shortened from several days to 0.5 h. Te doping and S filling simultaneously optimized the thermal and electrical transport properties of the CoSb3 materials. We found a porous architecture containing rich grain boundaries, different grain sizes, nano- to micrometer-sized pores, and a large number of dislocations, which can scatter a wide spectrum of phonons. Seebeck coefficient [Formula: see text], electrical resistivity [Formula: see text], and thermal conductivity [Formula: see text] were measured between 295 K and 773 K. The minimum thermal conductivity of S[Formula: see text]Co4Sb[Formula: see text]Te[Formula: see text] synthesized at 3.0 GPa was 1.23 Wm[Formula: see text] K[Formula: see text], and its maximum zT value reached 1.07 at 773 K, especially the lattice thermal conductivity was as low as 0.49 Wm[Formula: see text] K[Formula: see text].

Published: March 2024

As with IoT devices, cloud computation increases its applicability to other areas that use the information and puts it in a commonplace that is necessary for computing and analysis. These devices need the cloud to store and retrieve data since they are unable to store and process data on their own. Cloud computing offers a variety of services to consumers, including IaaS, PaaS, and SaaS. The usage of cloud resources for data storage that may be accessible by all users associated with cloud computing is a key disadvantage of cloud computing. Without disclosing the data’s contents, the usage of Public Key Encryptions with Keyword Search (PEKS) secures publicly encrypted keys against third-party search capabilities that are not trustworthy. PEKs provide a security risk every time Interior Keywords Guessing Attacks (IKGA) are discovered in the system since an unauthorized service estimates the keywords in the trapdoor. This issue can be resolved using various methodologies such as the Certificateless Fleshed Public Key Authenticated Encryption of Keyword Search (CL-HPAEKS), which also uses Altered Elliptic Curve Cryptography (MECC), and the Mutation Centred Flower Pollinations Algorithm (CM-FPA), which uses optimization in keys to be improving the algorithm’s performance. The system’s security is achieved by adding a Message Fragments 5 (MD5) scramble mechanism. The proposed system achieves system security of 96%, and it takes less time to implement than earlier encryption methods.
Retro Oesophageal Transfer of Contralateral C7 in Birth Brachial Plexus Injury – A Retrospective Study
Authors: KESAVAN Pradeep Kumar , BALAN Jyoshid R. , KUNNATH Ajai S. , ROY Vinu , PRASANNA Prince H. 
Published: March 2024

Background: Presence of available healthy nerve roots on the injured side determines the outcome after nerve reconstruction. Paucity of nerve roots warrants contralateral C7 harvest for optimal results. We aim to study the risks and benefits of retro oesophageal transfer of contralateral C7 root in infants with birth brachial plexus injury. Methods: Study was carried out from 2017 to 2022 in 13 children who have undergone retro oesophageal transfer of contralateral C7 root to affected side. Follow-up period ranged from 8 to 60 months after the surgery. Motor power assessment was done using by active movement scale. Results: Average active movement score for abduction was found to be 6, elbow flexion 5.7, elbow extension 5.8, wrist extension 3, wrist flexion 4, finger flexion 4.8 and finger extension 3.8, respectively. No neurological deficits, limb length anomaly noted in the normal upper limb after contralateral C7 harvest. Conclusions: Retro oesophageal transfer of contralateral C7 is a safe technique in birth brachial plexus injury. The advantage of retro oesophageal transfer is reduction in the length of nerve grafts, thus helping in early neurotisation of distal forearm and hand muscles. The large axonal output from contralateral C7 can be used to reconstruct different nerves without any residual deficits on the normal side. Level of Evidence: Level IV (Therapeutic)
Adipofascial Perforator Flaps for Peripheral Nerve Resurfacing after External Neurolysis
Authors: CALOTTA Nicholas A. , SHORES Jaimie T. , TUFFAHA Sami H. 
Published: March 2024

Background: External neurolysis is an important approach to treating symptomatic peripheral nerve entrapment. In cases of recurrent neurolysis or particularly extensive neurolysis, a paucity of overlying soft tissue for closure over the freshly liberated nerve presents a challenge to long-term surgical success as primary closure of this tissue may predispose the patient to recalcitrant epineural scarring. We report the intermediate term outcomes of the use of adipofascial perforator flaps as a means of vascularised tissue resurfacing of nerves in these difficult scenarios. Methods: We retrospectively reviewed patients undergoing external neurolysis for painful peripheral nerve lesions who subsequently had soft tissue reconstruction with local adipofascial flaps. Data with regard to age, gender, limb involved, duration of symptoms, number of prior surgeries, operative time, type of flap, vascular basis of flap, duration of follow-up, visual analogue pain score, monofilament sensory testing and complications were collected. Results: We included six patients (four women) with a minimum follow-up period of 17 months (range: 17–25 months). Age ranged from 39 to 60 years of age. Four cases involved the upper extremity and two the lower extremity. Symptoms had been present between 1 and 10 years. All operations utilised a local adipofascial flap perfused by a named perforating vessel emanating from an adjacent axial vessel. Operative time for flap creation and inset was 74 minutes, on average. There was one minor complication owing to superficial wound dehiscence. All patients reported substantial pain relief (≥five-point reduction on visual analogue scale; scores 0–3 at last follow-up) and objective sensory testing demonstrated improvement. Conclusions: Our report pays particular attention to surgical technique that is applicable to both upper and lower extremities in addition to intermediate term safety and pain outcomes.

Bilateral Dorsal Nail Curvature of the Thumb Distal Phalanx – A Case Report
Authors: FERNANDO Ashan Rabinath , WILKS Daniel James , MCCOMBE David Bryan , COOMBS Christopher John 
Published: March 2024

Congenital dorsal curvature of the distal phalanx has been previously described as ‘reverse Kirner’ or ‘ski-jump’ deformity. This report describes bilateral occurrence in the thumbs. A 13-year-old male presented with difficulty caring for his thumbnails and in picking up small objects. Examination showed dorsal curvature of the distal phalanges of both thumbs, with greater curvature of the right side. Radiographs showed wedge-shaped epiphyses and dorsal curvature without coronal plane deviation of the distal phalanges. There was objective and subjective decrease in function associated with lateral pinch and tripod grasp. The reported aetiopathogenesis for Kirner deformity cannot explain the observed dorsal curvature. The bilateral nature makes a secondary physeal cause unlikely and suggests an embryologic basis. Due to the noticeable deficits in function, operative intervention may be warranted. Level of Evidence: Level V (Therapeutic)

Published: March 2024

Abstract

Background:
We investigated the associations between several reproductive factors related to childbearing and the variation (V) measure (a novel, objective, single summary measure of breast image intensity) by menopausal status.

Methods:
Our study included 3,814 cancer-free women within the Nurses’ Health Study (NHS) and NHSII cohorts. The data on reproductive variables and covariates were obtained from biennial questionnaires closest to the mammogram date. V-measures were obtained from mammographic images using a previously developed algorithm capturing the standard deviation of pixel values. We used multivariate linear regression to examine the associations of parity, age at first birth, time between menarche and first birth, time since last pregnancy, and lifetime breastfeeding duration with V-measure, adjusting for breast cancer risk factors, including the percentage of mammographic density (PMD). We further examined whether these associations were statistically accounted for (mediated) by PMD.

Results:
Among premenopausal women, none of the reproductive factors were associated with V. Among postmenopausal women, inverse associations of parity and positive associations of age at first birth with V were mediated by PMD (percent mediated: nulliparity: 66.7%, P &lt; 0.0001; parity: 50.5%, P &lt; 0.01; age at first birth 76.1%, P &lt; 0.001) and were no longer significant in PMD-adjusted models. Lifetime duration of breastfeeding was positively associated with V [&gt;36 vs. 0 ≤1 months β = 0.29; 95% confidence interval (CI) 0.07; 0.52, Ptrend &lt; 0.01], independent of PMD.

Conclusions:
Parity, age at first birth, and breastfeeding were associated with postmenopausal V.

Impact:
This study highlights associations of reproductive factors with mammographic image intensity.
