Background Grief in parents has been described as a very intense long-lasting experience, characterized by deep sadness, and social isolation, therefore, the recommendation of scientific societies in pediatrics is to provide bereavement care to parents and relatives of deceased children who have previously been cared for by health professionals. Objetive A bereavement workshop for parents is proposed as an intervention strategy, providing accompaniment to the families of deceased patients who received pediatric palliative care (PPC). Methods This is a descriptive, qualitative, and exploratory study. Two focal group sessions were performed in 2019 with 23 families who were formal caregivers of pediatric patients in the Programa de Cuidando de ti (Program “Taking Care of You”), Cali, Colombia. These sessions, guided by the pediatric palliative care group. Data were analyzed using content analysis. Results 60 families received the personalized letter of condolences with invitation to the workshop, 23 families attended the workshop. From the gratitude activity, families made 49 thank you cards, the following categories were highlighted: Communication, Hope, compassion, acceptance, humanization, learning, gratitude, active listening, coping strategies, regards, faith and humanization. Conclusion Strategies that favor adequate emotional management of the grieving process should be promoted. This study reflects the perceptions of parents attending a bereavement workshop. It highlights the gratitude, feelings and reflections of the family members during the health process and the death of the child while receiving accompaniment by a pediatric palliative care team.

Published: October 2022

This paper applies topology optimization in combination with a genetic algorithm to design a coating structure for sound absorption in underwater applications. The coating is designed with a high broadband acoustic absorption of 0.94 ranging from 1 to 10 kHz by optimizing the cavity topology and the dimensions of the embedded steel scatterers. This study demonstrates the application process of the topology optimization with a genetic algorithm method and the optimization results of the optimization process stages. The absorption mechanism of the topology design is analyzed. The effects of different cavity compositions, steel scatterers, design ideas, material parameters, and acoustic incident angles on the sound absorption coefficients are investigated. These acoustic structures and the method provide more ideas for the design of coating structures for underwater sound absorption.

Published: October 2022

Background: The COVID-19 pandemic has adversely affected health care systems and dialysis access care in the US and across the globe. Beyond the initial challenges posed by the pandemic and despite the actions taken by health care leaders/organizations/professional societies such as the “Maintaining Lifelines for ESKD Patients” joint statement, there continues to be delays in providing timely care and performing elective and emergent dialysis access procedures worldwide. The aim of this study was to assess the global challenges associated with providing dialysis vascular access care across the international vascular access community during the pandemic. Methods: The American Society of Diagnostic and Interventional Nephrology (ASDIN) conducted an online survey in 2021, that was administered to an expert panel of dialysis vascular access specialists and global leaders spanning across the international community. The respondents who are members of ASDIN, Association of Vascular Access and InTerventionAl Renal physicians (AVATAR), Asia Pacific Society of Dialysis Access (APSDA), Peruvian Vascular Access Society (APDAV), and Australia/New Zealand Society of Interventional Nephrology (ANZSIN) reported their experiences in the care of dialysis vascular access, practice patterns, and challenges faced during the COVID pandemic. Results: Of the 53 individual surveys sent, 16 were opened and 11 (69%) responses were received from across the world and from different practice settings. The survey revealed the continued challenges facing the international community, the stark disparities in care delivery, supply chain disruption and logistical, regulatory, and financial issues that the global community continues to face in the ongoing pandemic. Conclusions: The COVID19 pandemic is far from over, and the challenges and barriers to providing dialysis access care seen on the initial ASDIN survey in the US seem to extend across the globe. We describe those results and discuss options, opportunities, and innovative tools to provide dialysis and access care during these trying times.

Published: October 2022

Background: The peripheral intravenous catheter (PIVC) is an important strategy for the treating the illness of pediatric patients. However, the success rate of traditional PIVC method, such as the landmark technique, might be significantly variable and unstable. The near infrared-assisted PIVC might be another option and the results can be revealed by a systemic review and meta-analysis of randomized clinical trials (RCT). Methods: A systematic search and a meta-analysis for the RCT of near infrared-assisted PIVC on pediatric patients. The near infrared-assisted and traditional PIVC was compared to evaluate the first time success rate, number of attempts, and attempt duration. Seven RCT studies and total 1068 pediatric patients were enrolled in this meta-analysis. The subgroup analysis of vessel grade difficulty was also performed. Results: The near infrared-assisted PIVC showed a significantly higher odds ratio of first time success rate when compared to traditional PIVC. In addition, the number of attempts and attempt duration were significantly reduced in the group of near infrared-assisted PIVC. At last, the subgroup analysis of vessel grade difficultly showed that the first time success rate was borderline significantly increased in the subgroup of difficult vessel grade. In addition, the number of attempts was significantly reduced in the subgroup of difficult vessel grade. Conclusions: The near infrared-assisted PIVC might be an option for the PIVC on pediatric patients. The advantages of increased first time success rate and decreased number of attempts and attempt duration should be considered by the clinicians and nurses.

Published: October 2022

Introduction: We have previously evaluated the usefulness of venocutaneous fistula (VCF), also called “dermatorrhea.” VCF is a technique of blood removal/return by advancing a dialysis cannula to the femoral vein for each hemodialysis session using a fistula created between the great saphenous vein and skin. Methods: In this study, we evaluated 46 limbs of 40 patients for whom VCF was created at our hospital between May 2017 and April 2022. In all the patients, it was difficult to construct an arteriovenous fistula or arteriovenous graft because of the general/vascular conditions. The usefulness of this method was evaluated based on the results of dialysis treatment after fistula creation and the use of fistula. Results: Fundamental evaluation confirmed the progression of vascular wall thickening over time. During clinical review, no serious complications were found in any patient during or after fistula creation surgery. The infection rate was 0.30/1000 days of fistula maintenance. Secondary patency rates by the Kaplan–Meier method were 87.0% at 1 year and 42.6% at 3 years. Conclusion: This method has demonstrated a good patency rate, low infection rate, and seems to be a potentially useful alternative in patients in whom it is difficult to establish vascular access.

Motivation: Prediction of cancer outcome is a major challenge in oncology and is essential for treatment planning. Repositories such as The Cancer Genome Atlas (TCGA) contain vast amounts of data for many types of cancers. Our goal was to create reliable prediction models using TCGA data and validate them using an external dataset. Results: For 16 TCGA cancer type cohorts we have optimized a Random Forest prediction model using parameter grid search followed by a backward feature elimination loop for dimensions reduction. For each feature that was removed, the model was retrained and the area under the curve of the receiver operating characteristic (AUC-ROC) was calculated using test data. Five prediction models gave AUC-ROC bigger than 80%. We used Clinical Proteomic Tumor Analysis Consortium v3 (CPTAC3) data for validation. The most enriched pathways for the top models were those involved in basic functions related to tumorigenesis and organ development. Enrichment for 2 prediction models of the TCGA-KIRP cohort was explored, one with 42 genes (AUC-ROC = 0.86) the other is composed of 300 genes (AUC-ROC = 0.85). The most enriched networks for both models share only 5 network nodes: DMBT1, IL11, HOXB6, TRIB3, PIM1. These genes play a significant role in renal cancer and might be used for prognosis prediction and as candidate therapeutic targets. Availability And Implementation: The prediction models were created and tested using Python SciKit-Learn package. They are freely accessible via a friendly web interface we called surviveAI at https://tinyurl.com/surviveai .
‘妈妈, I miss you ’: Emotional multilingual practices in transnational families
Authors: Curdt-Christiansen Xiao Lan , Iwaniec Janina 
Published: October 2022

Aims: This study explores how home language(s) are used in bilingual family members’ daily digital or non-digital interactions to demonstrate their emotions and affections for each other. The study investigates linguistic features and situated-language use of home language(s) in emotional negotiations between family members. In addition, it explores how multimodalities and languages are mixed to contribute to the interactional dynamics underlying ‘family talk’ and how children and adults position themselves emotionally in moment-to-moment interaction of family life. Methodology: This study involves six families from two transnational communities (Chinese and Polish) and it employs an ethnographic research design for data collection. Data and analysis: Data sources include recordings of mealtime conversations, daily WhatsApp/WeChat texts, and digital-mediated family talk recorded by the families themselves. Affective repertoire is used as an analytical framework. Findings and conclusions: The following five key features are identified in online or offline family talks regarding expression of emotionality: emojis, terms of endearment, diminutives, declaration of love and situated emotive language use. Originality: Unlike recent studies of emotions in bi-multilingual families, this study does not rely on surveys, memoirs, or interviews. Few studies have investigated how family members present their emotional expression in their daily communications, what role home/heritage language(s) actually play in communicating their emotional needs, and how these emotional expressions are manifested in their lived experiences and socialisation practices. Significance and implications: The findings contribute to FLP literature by looking into how emotions are involved in the practices of family life and the construction of familyness. Emotions, as a key factor in FLP, are directly related to parents’ perceptions of and investment in their heritage language. Although these perceptions are linked to the powerful societal languages that often represent educational possibilities, when it comes to emotional expressions, the primacy is given to the first language/heritage language.

Published: October 2022

During pulmonary rehabilitation (PR), patients receive individually tailored walking exercise training. The personalised nature of exercise prescription is a fundamental component of PR. Despite this, the measurement of physical activity (PA) has been limited to a ‘one size fits all’ approach and can be challenging to translate into clinically meaningful or real-world units, such as cadence. This discrepancy may partly explain the inconsistent evidence for the impact of PR on PA. It may also provide an opportunity to standardise PA assessment in the context of chronic respiratory disease (CRD) and PR, where field-based walking tests are routine measures. This technical note provides an example of how to develop personalised PA intensity thresholds, calibrated against an individual’s performance on the Incremental Shuttle Walking Test (ISWT; maximal) and Endurance Shuttle Walk Test (ESWT; sub-maximal). These are externally paced tests, with each level (speed) of the tests denoting a specific speed (intensity); ranging 1.8 km/h (ISWT Level 1) to 8.5 km/h (ISWT Level 12). From the ESWT, it becomes possible to evaluate adherence to each individual’s walking exercise prescription. Future research should explore this approach and its responsiveness to PR. It may be possible to extend this methodology with the inclusion of physiological parameters (e.g., heart rate, calorimetry, and oxygen consumption) to derive relative intensity markers (e.g. moderate-to-vigorous), accounting for individual differences in exercise capacity, under the same paradigm as PR exercise prescription.

Published: October 2022

Objective We aimed to explore the safety and diagnostic value of medical thoracoscopic lung biopsy in patients with unexplained diffuse interstitial lung disease (ILD) in a single center pilot study. Method We retrospectively analyzed clinical and pathological diagnostic data from 52 patients with diffuse ILD undergoing medical thoracoscopic lung biopsy. Results Forty-four cases of diffuse ILD were confirmed pathologically, giving a diagnostic rate of 84.6%. Among these 44 patients, 11 patients were diagnosed with cancer, including eight patients with lung adenocarcinoma, three patients with metastases; two from a gastrointestinal malignancy, and one from a granulosa cell tumor of the ovary. There were 17 cases of idiopathic interstitial pneumonia, including nine cases of usual interstitial pneumonia (UIP), four cases of non-specific interstitial pneumonia (NSIP), three cases of cryptogenic organizing pneumonia (COP), and one case of acute interstitial pneumonia (AIP). There were 12 cases of rare interstitial pneumonias, which included six cases of pulmonary alveolar proteinosis, one case each of pulmonary Langerhans cell histiocytosis (LCH) and pulmonary lymphangiomyomatosis, two cases of nodular sarcoidosis, and two cases of chronic eosinophilic pneumonia. We recorded various complications, including bleeding, infection, and pneumothorax. A total of 28 patients (53.8%) experienced at least one of the above complications, but there were no deaths associated with biopsy. Conclusions Medical thoracoscopic lung biopsy appears a safe and effective method for diagnosing diffuse ILD of unknown cause but further prospective studies, with larger numbers, including comparison with other established techniques are required.

Authors: Yan Ruosi , Chen Lu , Wu Mengjin , Jia Lixia , Hou Mohan 
Published: October 2022

This study reveals the mechanical and interfacial bonding properties of glow discharge oxygen plasma modified ultrahigh molecular weight polyethylene (UHMWPE)/vinyl ester composites modified by oxygen plasma. The composites’ flexural, tensile, and impact-resistant properties were estimated, and the failure mechanism was analyzed by acoustic emission (AE) testing. The flexural stress, tensile stress, and impact-resistance force of the modified three plain weave structures composites are 193.37–734%, 11–15%, and 16–17% higher than those without modification. It depends on flexibility, interfacial bonding strength, reinforcement structure, and stiffness. In addition to the flexural properties, the tensile and impact properties increase with fiber volume fraction. In the AE test, the flexural and tensile cumulative energies without modification are 9230.42 mV*mS and 1.735 V*S higher than modified materials. The characteristic frequency range of each failure mechanism is determined by cluster analysis. Low, medium, and high frequency correspond to matrix cracking, fiber/matrix debonding, and fiber breakage. Oxygen plasma contributes to the wettability of the reinforcement and the interfacial bonding strength, resisting cracking growth.

It has been reported through various studies that turmeric of different geographical regions has variabilities regarding the number of phytochemicals, some have a better curcuminoid yield, some have better antimicrobial and antioxidant activities, and even turmeric of some regions does not show compatibility with modern applications due to having unfavorable quality. So, here in this study, we have tried to demonstrate the potential and efficacy of locally produced turmeric powder from district Kasur, Pakistan, through a comparative study with turmeric powder of international grade, analyzing their activity against pathogenic micro-organisms, presence of the number of phytochemicals, and presence of curcuminoid compounds like curcumin, extracted in four different solvents (ethanol, methanol, acetone and chloroform), and were verified by TLC and FTIR spectroscopy. This study justifies that the locally produced turmeric has better quality and potential as it gives a maximum curcuminoid yield of about 25% in Ethanol solvent and showed maximum zone of inhibition against E.coli about 14mm and 16mm against Staphylococcus aureus. While Antifungal activity was also observed high; as compared to the same amount of does of international grade turmeric extract. Further, electrospun nanofibers successfully generated from curcuminoid of Kasur Pakistan with PVA, present uniform, smooth nanofibers with an average diameter of 227. 49 nm. Finally, this study suggests that turmeric of Kasur has similar or more potential as compared to turmeric of international grade, and can be used/replaced in nanotechnology labs for various applications.

Published: October 2022

Polymeric membranes show great potential for treating wastewater containing oil/water emulsions, which can cause serious environmental pollution. In this paper, novel polyvinylidene fluoride-co-hexafluoropropyle/graphene (PVDF-HFP/GE) tubular nanofiber membranes (TNMs) were fabricated by electrospinning and thermal treatment. The prepared TNMs were post-treated under different thermal treatment conditions to obtain 3-dimensional (3D) structures. The effects of thermal treatment time and temperature on membrane structure and performance were investigated by field-emission scanning electron microscopy, hydrophobicity, pore size and distribution, porosity, and liquid entrance pressure. After thermal treatment, more graphene was exposed to the membrane surface, which provided excellent oil/water selective wettability and anti-fouling performance. In addition, the thermally treated TNMs possessed an optimal pore structure and could separate surfactant-stabilized water-in-oil emulsions at high filtration rates (497.5 ±13.3 L·m−2·h−1) and separation efficiency (>99%). Moreover, the filtration rate and separation efficiency remained constant over 10 filtration cycles, showing that these membranes have great potential for application to practical oil/water separation processes.

Published: October 2022

Oil spill pollution is a constant threat to the environment nowadays. The treatment of an oil spill remains a challenge to environmental scientists. Among the various cleanup methods available, the use of sorbents for oil spill cleanups is a popular approach. In this work, an attempt has been made to produce cotton comber noil /recycled polyester needle punched nonwoven fabrics for the oil spill clean-up process. Box–Behnken experimental design is used to optimise the parameters such as cotton comber noil /recycled polyester blend proportion, needle punching density and areal density for maximum oil sorption capacity. At 70:30 cotton comber noil /recycled polyester blend proportion, 64.94 needle punching density and 100 GSM, maximum oil sorption was achieved. The maximum oil sorption achieved in the case of crude oil and vegetable oil is 45.90 g/g and 32.30 g/g respectively. The cotton comber noil/recycled polyester needle punched nonwoven fabric showed a stable water bead morphology with a static contact angle of 133.6. The present work indicates that the cotton comber noil/recycled polyester needle punched nonwoven fabric (70/30) is a potential sustainable product for oil spill removal applications.
