Structural Design and Optimization of Nonuniform Chiral Phononic Crystals for Vehicle Interior Noise Reduction
Authors: Yuan Tao , Guo Hui , Wang Yansong , Sun Pei , Wang Yi
Published: June 2023

Phononic crystals (PnCs) with nonuniform and chiral design are developed and applied for the reduction of vehicle interior noise. To investigate the effects of structural parameters such as the lattice arrangements and the filling rates, locally resonant PnCs (LRPnCs) are established for calculating sound insulation and bandgap characteristics. Furthermore, the nonuniform LRPnCs with Greek-cross chiral structure are constructed. To improve the sound insulation characteristics of the nonuniform chiral LRPnCs, a genetic algorithm (GA) optimization procedure is performed. Accordingly, the modified nonuniform chiral LRPnCs is designed and simulated to predict the sound insulation characteristics. Experimental verification suggests that the simulated results are in good agreement with the tested ones. The newly designed nonuniform chiral LRPnCs are effective in vehicle interior noise reduction. All the works are expected to be extended to other sound-related fields for noise reductions in engineering.

Authors: Wulandari Poppy , Ibrahim Maulana
Published: June 2023

Fintech lending plays significant role in Indonesia as a developing country where the need for loan funds is very high. Although the reason for the significant growth of fintech lending in Indonesia is motivated by the consumerist nature of the Indonesian people in the use of loan funds, the presence of fintech lending has also become a solution in the ease of obtaining loan funds. In Indonesia, fintech lending services are not only available on fintech lending platforms, but are also available on e-commerce. This study aims to examine the practice of business ethics in fintech lending services provided by Shopee's collaboration with Lentera Dana Nusantara (LDN), namely SPinjam. This study uses a qualitative research method with a normative juridical approach. The collection of data in this study comes from primary and secondary data sources. In this study, interview results from informants were processed using MAXQDA Standard software to interpret the results systematically. For the sake of the validity of the research results, this study also involved a triangulation approach to check the correctness of the data from information obtained from primary and secondary sources. Even though the results of this study show a tendency for good business ethics from SPinjam, there are still findings indicating that the regulations in SPinjam are not transparent, especially regarding information about the amount of interest charged to users.

The objective of the study was to characterize the profile and complaints of patients who sought psychological help from three services provided by a university in São Paulo, Brazil, during the pandemic. The study analyzed and compared data obtained in the survey from the three psychological services and verified the characteristics of telemental health. This is a retrospective and comparative research, carried out by surveying the profile and complaints of people who sought psychological help during the defined period, through the analysis of registration forms and screening notes of the participants who expressed consent. The final sample comprised 628 participants, of which 76.2% were women, with average age of 36.6 years. The main complaint reported in the three services was anxiety, followed by depression. Telehealth for mental care showed positive aspects, such as enabling the reception of patients during the period of social distancing. The following difficulties stand out: confidentiality, lack of a protected environment for the sessions, and issues imposed by internet connection and use of technology.
Elucidating metabolic tuning of mixed purple phototrophic bacteria biofilms in photoheterotrophic conditions through microbial photo-electrosynthesis
Authors: Edreira Sara Diaz-Rullo , Vasiliadou Ioanna , Prado Amanda , Espada Juan , Wattiez Ruddy , Leroy Baptiste , Martinez Fernando , Puyol Daniel
Published: June 2023

The reduction of greenhouse gas emissions is a red tag for humanity nowadays, but it can be beneficial through developing engineered systems that valorize CO2 into commodities, thus mimicking nature's wisdom. Purple phototrophic bacteria (PPB) naturally accept CO2 into their metabolism as a primary redox sink system in photo-heterotrophy. Dedicated use of this feature for developing sustainable processes (e.g., through negative-emissions photo-bioelectrosynthesis) requires a deep knowledge of the inherent metabolic mechanisms. This work provides evidence of tuning the PPB metabolic mechanisms upon redox stressing through negative polarization (-0.4 and -0.8 V vs. Ag/AgCl) in photo-bioelectrochemical devices. A mixed PPB-culture upregulates its ability to capture CO2 from organics oxidation through the Calvin-Besson-Bassam cycle and anaplerotic pathways, and the redox imbalance is promoted to polyhydroxyalkanoates production. The ecological relationship of PPB with mutualist bacteria stabilizes the system and opens the door for future development of photo-bioelectrochemical devices focused on CO2 up-cycling.

Air embolism during thoracic endovascular aortic repair (TEVAR) is associated to an incomplete deairing of the delivery system (DS) despite the saline lavage recommended by the instructions for use (IFU). As the DSs are identical, endovascular aortic repair (EVAR) can be used to examine the effectiveness of deairing maneuvers. We aimed to evaluate if a more complete deairing can be achieved with increasing the flush volume. EVAR patients were randomised according to flushing volume (Group A:1xIFU & Group B: 4xIFU). Air trapped in the aneurysm sac was quantified on pre-discharge CTA. 30 patients were enrolled and equally distributed between the two groups. There were no differences in any demographic or anatomical factors. Presence of air was less frequent in Group A than in Group B (7 (47%) vs. 13 (87%), p = .02), volume of air was less in Group A compared to Group B (103.5 ± 210.4 vs. 175.5 ± 175.0 mm3, p = .04). Volume of trapped air was higher with Anaconda graft type (p = .025). Increased flushing volume is associated with more trapped air, thus following the IFU might be associated with smaller risk of air embolization. Significant differences were identified between devices regarding the amount of trapped air.

Background and purpose: The purpose of this study was to evaluate the safety and efficacy of preoperative concurrent chemoradiotherapy (preCRT) for locally advanced rectal cancer in older people who were classified as “fit” by comprehensive geriatric assessment (CGA).
Methods: A single-arm, multicenter, phase II trial was designed. Patients were eligible for this study if they were aged 70 years or above and met the standards of “fit” (SIOG1) as evaluated by CGA and of the locally advanced risk category. The primary endpoint was 2-year disease-free survival (DFS). Patients were scheduled to receive preCRT (50 Gy) with raltitrexed (3 mg/m2 on days 1 and 22).
Results: One hundred and nine patients were evaluated by CGA, of whom eighty-six, eleven and twelve were classified into the fit, intermediate and frail category, Sixty-eight fit patients were enrolled. Sixty-four patients (94.1%) finished radiotherapy without dose reduction. Fifty-four (79.3%) patients finished the prescribed raltitrexed therapy as planned. Serious toxicity (grade 3 or above) was observed in twenty-four patients (35.3%), and fourteen patients (20.6%) experienced nonhematological side effects. Within a median follow-up time of 36.0 months (range: 5.9-63.1 months), the 2-year overall survival (OS), cancer-specific survival (CSS) and disease-free survival (DFS) rates were 89.6% (95% CI: 82.3-96.9), 92.4% (95% CI: 85.9-98.9) and 75.6% (95% CI: 65.2-86.0), respectively. Forty-eight patients (70.6%) underwent surgery (R0 resection 95.8%, R1 resection 4.2%), the corresponding R0 resection rate among the patients with positive mesorectal fascia status was 76.6% (36/47).
Conclusion: This phase II trial suggests that preCRT is efficient with tolerable toxicities in older rectal cancer patients who were evaluated as fit based on CGA.

Authors: Mesquita Fernanda Vieira , Ferreira Vanessa , Mesquita Danilo , Andrade Luis Eduardo Coelho
Published: June 2023

Background: Serum from systemic lupus erythematosus (SLE) patients has been shown to induce T-lymphocyte (TL) apoptosis. Given that different cells of the immune system display different sensitivity to apoptosis, we set to evaluate the in vitro effect of SLE serum on regulatory T-cells (Treg), Th17, Th1 and Th2 from SLE patients and healthy controls.
Methods: Peripheral blood mononuclear cells from SLE patients or normal controls were exposed to a pool of sera from SLE patients or normal controls. Annexin V was used to label cells in apoptosis or necrosis. Annexin V-labeled Treg, Th17, Th1 and Th2 cells were determined using flow cytometry.
Results: Total CD3+ and CD4+ cells from SLE patients showed higher frequency of spontaneous apoptosis/necrosis than cells from controls, whereas Th1 cells from SLE patients presented reduced spontaneous apoptosis/necrosis rate as compared with cells from controls. Total CD3+ and CD4+ cells from normal controls incubated with SLE serum presented increased frequency of apoptotic/necrotic cells as compared with cultures incubated with normal human serum (NHS) or without human serum at all. Treg cells from SLE patients were more prone to apoptosis/necrosis induced by SLE serum than Treg cells from normal individuals. Incubation with SLE serum did not increase the apoptosis/necrosis rate in Th1, Th2 or Th17 cells. Th1 and Th17 cells presented increased apoptosis rates in cultures without human serum.
Conclusion: Our findings indicate that the serum of patients with active SLE stimulates apoptosis of CD4+ T cells in general and exhibit differentiated effects on CD4+ T-cell subsets.

Numerous chemical pesticides have been used in agricultural production to combat crop diseases and pests. Despite ensuring certain economic advantages, they have also resulted in issues like environmental contamination, declining soil quality, and pesticide residues. Because biological control is environmentally friendly and difficult to acquire resistance to, it has been used in practice recently. We isolated the endophytic fungus Purpureocillium lilacinum from Portulaca oleracea L., which was previously found to have inhibitory effects on soil pathogens in tobacco fields. In order to explore the effects of the biocontrol agent Purpureocillium lilacinum on soil microorganisms and plant metabolism in tobacco cultivation, we combined amplicon sequencing technology and gas chromatography-mass spectrometry to carry out the analysis of soil microbial community structure and microbial-metabolite interaction network in inter-rhizosphere soil of tobacco field under different application method of P. lilacinum treatment. The findings showed that there was a trend toward less microbial diversity among inter-root microorganisms as solid-state fermentation (SSF) products of P. lilacinum increased; however, submerged fermentation (SmF) had no discernible impact on microbial diversity when compared to the direct use of SSF. Additionally, the relationship between inter-root fungi and volatile compounds of tobacco leaves was dominated by a negative correlation. The result demonstrated that P. lilacinum's antagonistic interaction in the inter-rhizosphere microbial community was dominant and valuable for biopesticide application. P. lilacinum can work more effectively on tobacco roots by using SSF products. P. lilacinum's opposition to fungal colonies may enhance the volatile chemicals in tobacco leaves.

with the growing population in the entire world, especially in under develop countries, the traffic problems are arising with high ratio. The people are using cars, bikes, trains and buses to research at destination. The rush on the roads has been increased rapidly and traffic controlling issues are at worst condition. In year 2030, the traffic will be double and the resources will be almost same. The major issue is to control traffic and conjunction in future automatically. One way is to construct new roads overhead and underground bridges but it is not possible in under developing countries like Pakistan, India and Bangladesh, etc. The other solution is to implement automatic system with the combination of IoT and blockchain and sensors to address this issue. The automatic system must be intelligent to detect changes in traffic conditions and automatically change the traffic signal timings to control congestion. For this purpose, videos cameras and IoT network sensors can be used to sense the condition, position of vehicles at a traffic signal and send information to control room or change signaling time automatically for optimum performance. In this research compare different methods to resolve above issue and matrix method will be analyze to address the issue. For simulation, the matlab simulation tool will be use.

Adverse Childhood Experiences (ACEs) are events that occur before a child turns 18 years old that may cause trauma. In this study, the effect of cumulative ACEs experienced on human maternal DNA methylation (DNAm) was estimated while accounting for interaction with domains of ACEs in prenatal peripheral blood mononuclear cell samples from the Maternal and Developmental Risks from Environmental Stressors (MADRES) pregnancy cohort. The intergenerational transmission of ACE-associated DNAm was also explored used paired maternal and neonatal cord blood samples. Replication in buccal samples was explored in the Children’s Health Study (CHS). We used a four-level categorical indicator variable for ACEs exposure: none (0 ACEs), low (1–3 ACEs), moderate (4–6 ACEs), and high (> 6 ACEs). Effects of ACEs on maternal DNAm (N = 240) were estimated using linear models. To evaluate evidence for intergenerational transmission, mediation analysis was used. Analysis of maternal samples displayed some shared but mostly distinct effects of ACEs on DNAm across low, moderate, and high ACEs categories. CLCN7 and PTPRN2 was associated with maternal DNAm in the low ACE group and this association replicated in the CHS. ACE-associated methylation was observed in maternal and neonatal profiles in the COMT promoter region, with some evidence of mediation by maternal COMT methylation. Specific genomic loci exhibited mutually exclusive maternal ACE effects on DNAm in either maternal or neonatal population. There is some evidence for an intergenerational effect of ACEs, supported by shared DNAm signatures in the COMT gene across maternal-neonatal paired samples.

Published: June 2023

The prediction of household food price index has always been a significant challenge for the food industry, especially in developing countries like India, where the majority of the population depends on agriculture for their livelihoods. In this project, we aim to develop a food price index prediction system for household food items like cereals, millets, and pulses using three popular time-series forecasting models, namely SARIMA, ETS, and FB Prophet. We use historical price index data to build and evaluate the forecasting models. The performance of each method is assessed using evaluation metrics such as MAE and RMSE. The results show that all three methods can effectively predict the demand for food items with high accuracy. However, FB Prophet has better performance than the other two methods when it comes to forecasting accuracy and computation time. This project presents a food prediction model that can be used by grocery stores and households to effectively plan and manage their food inventory. The study highlights the effectiveness of time series forecasting techniques such as SARIMA, ETS, and FB Prophet in predicting the demand for household food items, which can aid in reducing food wastage and improving food supply chain management The developed forecasting model can help retailers and suppliers to manage their inventory and plan their production based on the predicted demand for household food items. Additionally, this study provides valuable insights into the application of time series forecasting methods in the food industry.
Great Lakes coastal wetland biodiversity increases following invasive Phragmites australis removal
Authors: Ward Meghan , Degazio Tarra , Bowman Jeff
Published: June 2023

Invasive Phragmites australis subsp. australis is invading Great Lakes coastal wetlands and forming monocultures at an alarming rate. P. australis is thought to reduce wetland biodiversity both directly and indirectly through the acquisition of resources and alteration of habitat. Restoration efforts to manually remove P. australis at Point Pelee National Park began in 2020 and here we assess the effect of P. australis removal on vegetation and emerging aquatic invertebrate communities. We compared emergent vegetation and emerging aquatic invertebrate communities between a P. australis-invaded wetland, a P. australis-treated wetland, and a non-invaded wetland. We found that two-years post-restoration, vegetation species richness and the prevalence of non-Phragmites vegetation were both higher in the treated and non-invaded wetlands than the invaded wetland. The vegetation community of the treated wetland resembled the vegetation community of the non-invaded wetland, and the vegetation community of the invaded wetland was very different from both the treated and non-invaded wetlands. We also found that invertebrate total abundance (measured as density/m2) was highest in the treated and non-invaded wetlands, and that invertebrate abundance differed among all wetland types. Invertebrate community composition also differed among all wetland types. Manual removal of P. australis resulted in significant changes in both the emergent vegetation and emerging invertebrate community composition two-years following restoration.

Data collected: smoking status, thyroid-stimulating hormone receptor antibody (TRAb) status, GO history, Graves’ disease duration, eye features pre- and post-treatment, prophylactic corticosteroids, RAI dose given, post-RAI thyroid status, duration until hypothyroid.
Results: 101 patients were included, with median Graves’ disease duration 36 months. 34/101 (33.7%) were active/ex-smokers, 86/101 (85.1%) were TRAb-positive, 11/101 (10.9%) had a GO history; 32 (31.7%) had eye features present. Median RAI dose given was 596MBq. 8/101 (7.9%) patients received prophylactic corticosteroid; 1 experienced a wrist fracture. 89/101 (88.1%) achieved hypothyroid state in the year after RAI. GO developed in 5/101 (5.0%), of which 4/5 (80%) were de novo in high-risk individuals who did not receive steroids. One was a GO reactivation despite steroids. Two required intravenous steroids with/without orbital radiotherapy, one completed oral steroid taper; the remainder were treated conservatively.
Conclusion: Our cohort had a lower GO incidence in patients with Graves’ disease receiving RAI, with majority arising de novo. It is essential that all patients are assessed for eye disease or risk factors and counselled adequately prior to RAI. The decision to initiate steroids should be undertaken in a multi-disciplinary setting involving endocrinologists and ophthalmologists.
Comorbidity and drug resistance of smear-positive pulmonary tuberculosis patients in the Yi Autonomous Prefecture of China: a cross-sectional study
Authors: Wang Tao , Zhou Chaoxin , Shang Lan , Zhou Xiyuan
Published: June 2023

Background
Tuberculosis (TB) has a high morbidity and mortality rate, and its prevention and treatment focus is on impoverished areas. The Liangshan Yi Autonomous Prefecture is a typical impoverished area in western China with insufficient medical resources and high HIV positivity. However, there have been few reports of TB and drug resistance in this area.
Methods
We collected the demographic and clinical data of inpatients with sputum smear positive TB between 2015 and 2021 in an infectious disease hospital in the Liangshan Yi Autonomous Prefecture. Descriptive analyses were used for the epidemiological data. The chi-square test was used to compare categorical variables between the drug-resistant and drug-susceptible groups, and binary logistic regression was used to analyse meaningful variables.
Results
We included 2263 patients, 79.9% of whom were Yi patients. The proportions of HIV (14.4%) and smoking (37.3%) were higher than previously reported. The incidence of extrapulmonary TB (28.5%) was high, and the infection site was different from that reported previously. When drug resistance gene detection was introduced, the proportion of drug-resistant patients became 10.9%. Patients aged 15–44 years (OR 1.817; 95% CI 1.162–2.840; P < 0.01) and 45–59 years (OR 2.175; 95% CI 1.335–3.543; P < 0.01) had significantly higher incidences of drug resistance than children and the elderly. Patients with a cough of ≥ 2 weeks had a significantly higher chance of drug resistance than those with < 2 weeks or no cough symptoms (OR 2.069; 95% CI 1.234–3.469; P < 0.01). Alcoholism (OR 1.741; 95% CI 1.107–2.736; P < 0.05) and high bacterial counts on sputum acid-fast smears (OR 1.846; 95% CI 1.115–3.058; P < 0.05) were significant in the univariate analysis.
Conclusions
Patients with Sputum smear positive TB who were hospitalised in this hospital had higher proportions of Yi nationality, smoking, HIV, and extrapulmonary TB. Ages 15–59 years and cough duration ≥ 2 weeks were risk factors for TB drug resistance. Meanwhile, alcohol abuse and high bacterial counts in sputum acid-fast smears may also be associated with TB drug resistance. These characteristics are related to poverty and insufficient health resources.
Analysis of the Morphological Design Features of the Hospital Physical Facilities in Southwest, Nigeria
Authors: AKINLUYI Muyiwa
Published: June 2023

This study analyzed the morphological design features of the hospital physical facilities in Southwest, Nigeria. The research work is a reflection of a positive trend that can affect the quality of healthcare facilities design in the years to come. A lot of research work has evaluated different aspects of hospital design features while only few of the previous studies included design characteristics in terms of morphological configuration of the physical facilities in their conceptual framework. As a result, hospital facilities are poor at meeting the needs and expectations of users due to the limited studies on users’ assessment of the morphological design characteristics which have not been clearly understood and adequately carried out within the research circle. This is suggested in this study to provide better solutions to the problem. This study adopted a primary method of data collection which involved the use of 557 structured questionnaires randomly administered to three categories of users and semi-structured interviews (SSI) purposely administered to users to support the information obtained through the questionnaires. Through purposive sampling, buildings were restricted to four (4) buildings that accommodate 4 main departments which gave birth to other departments such as paediatrics, surgery, medicine, obstetrics and gynaecology at the Federal Universities Teaching Hospitals (FUTH) in southwest, Nigeria built between 1950s and 1970s and managed by the Federal Government of Nigeria. Data obtained was analysed at univariate, bivariate and at multivariate levels. The morphological design characteristics such as the volume in terms of size and proportion, aesthetics, size of the components in most interior spaces are very adequate while other interior spaces need urgent attention. The study helps the hospital policy makers in making appropriate decisions that can improve the healthcare environment in Nigeria.

Vivid neo-cartilage growth was detected with initially outnumbered chondrocytes in the porcine model following transplantation of a three-dimensional (3D)-printed tracheal graft. Virtual silicone tracheal grafts, each of 2 cm long, were first generated with a 3D printer, and underwent a physical stress test to resemble a trachea from the 3-month-old porcine. The grafts underwent end-to-end anastomosis for the proximal and distal parts of the trachea after cuff resection. Tissue samples were grossly examined, and their histological properties examined by protein expressions through the use of H&E, alcian blue, safranin O/fast green stain and immunohistochemistry (IHC) assay for Sox9, type II collagen, aggrecan and PCNA, respectively. These primitive cartilages showed chondrogenesis with outnumbered chondrocytes, and they evolved to a mature stationary status with cartilage corrosion through interim PP, PRL and VC chondro-modulators elaborated from perichondrium. Matrix degradation products with alcian blue staining were removed to VCs, and the adjacent mucosal and submucosal glands. Chondrogenesis underwent an incipient burst of growth in conjunction with the perichondrium involving a process of graduate consolidation, as evidenced by matrix degradation product emissions on the mucosa and submucosa. We proposed 5 stages to characterize the regenerative chondrogenesis of the tracheal cartilage.

The number of diabetic foot ulcer patients is substantially increasing, with the rapidly rising burden of diabetic mellitus in sub-Saharan Africa. The data on the regional prevalence of diabetic foot ulcer infecting bacteria and their antimicrobial resistance patterns is crucial for its proper management. This systematic review and meta-analysis determined the pooled prevalence of bacterial profiles and antimicrobial resistance patterns of infected diabetic foot ulcers in sub-Saharan Africa. A comprehensive search of the literature was performed on CINAHL, EMBASE, Google Scholar, PubMed, Scopus, and Web of Science databases. Critical appraisal was done using the Joanna Briggs Institute’s tool for prevalence studies. A pooled statistical meta-analysis was conducted using STATA Version 17.0. The I2 statistics and Egger’s test were used to assess the heterogeneity and publication bias. The pooled prevalence and the corresponding 95% confidence interval of bacterial profiles and their antimicrobial resistance patterns were estimated using a random effect model. Eleven studies with a total of 1, 174 study participants and 1, 701 bacteria isolates were included. The pooled prevalence of the most common bacterial isolates obtained from DFU were S. aureus (34.34%), E. coli (21.16%), and P. aeruginosa (20.98%). The highest pooled resistance pattern of S. aureus was towards Gentamicin (57.96%) and Ciprofloxacin (52.45%). E.coli and K. Pneumoniae showed more than a 50% resistance rate for the most common antibiotics tested. Both gram-positive and gram-negative bacteria were associated with diabetic foot ulcers in sub-Saharan Africa. Our findings are important for planning treatment with the appropriate antibiotics in the region. The high antimicrobial resistance prevalence rate indicates the need for context-specific effective strategies aimed at infection prevention and evidence-based alternative therapies.

Background
Accurate assessment of body composition during infancy is important, especially for understanding the effects of early growth on later health. This study aimed to develop an anthropometry-based approach to predict body composition in 3–24 month old infants from diverse socioeconomic settings and ethnic groups.
Methods
An observational, longitudinal, prospective, multinational study of infants from birth to 24 months. Body composition was assessed at 3, 6, 9, 12, 18, and 24 months using deuterium dilution (DD) and anthropometry.
Linear mixed modelling was utilized to generate sex-specific fat mass(FM) and fat-free mass(FFM) prediction equations. Length(m), weight-for-length(kg/m), triceps and subscapular skinfolds and Asian ethnicity were used as predictor variables.
The study sample consisted of 1896(942 measurements from 310 girls) training data sets, 941(441 measurements from 154 girls) validation data sets from Brazil, Pakistan, South Africa and Sri Lanka, and 349(185 measurements from 124 girls) data sets of infants at 6 months from South Africa, Australia and India of external validation group.
Results
Sex-specific equations for three age categories (3-9 months; 10-18 months; 19-24 months) were developed and validated and an external validation was performed on the test group.
The root mean squared error(RMSE) was similar between validation and test data for assessment of FM and FFM. Root mean squared percentage error(RMSPE) and mean absolute percentage error(MAPE) in validation data were higher for predicting FM but lower for FFM compared to test data.
Conclusions
Anthropometry-based FFM prediction equations provide acceptable results which have the potential to be developed as a field tool.
