Published: August 2024

Abstract

Background
Burn patients, due to their damaged skin, may not be able to synthesize vitamin D. In this study, we aimed to evaluate the effects of vitamin D supplementation on the recovery of hospitalized burn patients.
Methods
Fifty-four patients participated in a randomized controlled trial. Eighteen patients were randomly assigned to group C (control, received gelatin soft gel as placebo), 18 patients to group D1 (received 1000 IU/day vitamin D), and 18 patients to group D2 (received 3000 IU/day vitamin D). After supplementation, wound biopsy and blood samples were obtained from the patients. Weight, height, 25(OH)D level, wound healing, scar formation, quality of pain, and blood parameters were evaluated.
Results
There were no significant differences in the serum vitamin D levels between the groups at admission, and 81.5% of the participants were deficient. The Bates–Jensen Wound Assessment Tool demonstrated significant differences in wound healing between the C group and the D1 and D2 groups, and the supplemented groups experienced greater improvement. The D2 group showed significant differences in thickness and total score on the Vancouver scar scale up to three months after discharge (P = 0.03). Moreover, there was a notable decrease in insulin requirements and the number of injected insulin units in the supplemented groups compared with those in group C (P = 0.006 and P = 0.01, respectively). In addition, shorter hospitalization was observed in group D2 (P = 0.04).
Conclusion
Supplementation with vitamin D at doses of 1000 and 3000 IU/day improved wound healing and decreased scar thickness as well as exogenous insulin requirements. Overall, at 3000 IU/day, better results were achieved than at 1000 IU/day.

Abstract

Background
We previously showed that total tumor resection enhances metastatic growth in a syngeneic metastatic mouse model of neuroblastoma. In this study, we further investigated which surgical factors contributed most to metastatic growth.
Methods
Tumor cells derived from MYCN transgenic mice were subcutaneously injected into wild-type mice. Mice were randomly assigned to receive partial resection (PR group), subcutaneous implantation of a sponge (Sp group), or observation (Obs group). The lymph node metastasis volume and frequency of lung metastasis were compared 14 days after assignment by measuring C-reactive protein (CRP) and interleukin-6 (IL-6) levels.
Results
The lymph node metastasis volume in the Sp group was larger than in the Obs group (148.4 [standard deviation {SD}: 209.5] vs. 10.2 [SD 12.8] mm3). The frequency of lung metastasis was greater in the Sp group than in the PR group (11.9 [SD 12.2] vs. 6.6 [SD 4.0] counts/slide). The CRP level in the Sp group was higher than in the PR group (2.3 [SD 0.5] vs. 1.5 [SD 0.4] µg/mL), and the IL-6 level in the Sp group was higher than in the PR or Obs groups (28.4 [SD 34.5] vs. 12.4 [SD 19.0] vs. 5.4 [SD 8.1] pg/mL).
Conclusion
Metastatic growth may be enhanced by systemic inflammation.

Abstract

Background: The study aims to describe a rare case of pulmonary anthracosis in a free-ranging infant rhesus monkey in Bangladesh.
Case presentation: An infant Rhesus monkey (Macaca mulatta) just under 1 year of age died suddenly in a veterinary hospital in Bangladesh under treatment period with clinical signs of loss of appetite, gradual weight loss, weakness, dehydration, depression, breathing difficulty, and mild nasal discharge. The experienced veterinarian performed the postmortem examination of the infant monkey, collected samples from different organs, and sent them to the Department of Anatomy and Histology at Chattogram Veterinary and Animal Sciences University (CVASU) for confirmatory diagnosis. A grossly considerable number of evenly distributed black spots were observed in the entire lungs. Moreover, both lungs were inflamed, firm, swollen, and discolored, but there were no nodules or fibrosis. Microscopically, black-colored carbon particles, inflammatory cells, edematous fluid, and brown color hemosiderin-laden macrophages were found in the interstitial space. Diffuse alveolar damage along with exudate and carbon particles were found in the alveoli.
Conclusion: The infant rhesus monkey died of cardiopulmonary failure due to chronic respiratory distress. The pulmonary anthracosis indicated that air quality was poor in the habitat and may pose a health risk to wild animals and humans.

Published: August 2024

Abstract

This study investigated the effect of different ratios of CNT (carbon nanotube) additive on various properties of PVC/PMMA (poly (vinyl chloride/poly(methyl methacrylate)) blend. For this purpose, a nanocomposite was prepared by adding 0, 0.1, 0.5, and 1% CNT (carbon nanotube) to the PVC/PMMA blend, which was prepared by casting technique from a common solvent. Spectroscopic and thermal analyses were carried out on the prepared nanocomposite samples. SEM imaging showed that CNTs showed good distribution and interaction in the polymer matrix. XRD analyses showed the amorphous character of the structure, and CNT doping did not create any significant changes in crystallinity. The highest crystallinity was found in PVC40-1 at 15.24%. All the samples had similar Tg (Glass transition Temperature) values in the DSC analysis. The existence of CNT did not affect Tg values. CNTs helped to preserve the integrity of nanocomposite because the rate of degradation of nanocomposite without CNT reached its highest values (258.95–514.19W/min) in the DTG. TGA analysis showed that all the weight loss curves of the samples looked similar. Weight loss occurred at 194, 249, and 442°C and all of them were very similar. CNTs did not change the electrical conductivity of the nanocomposite. A fragility was observed in the structure of the nanocomposite.

Abstract

Introduction:
This research explores the challenges posed by variations in cystic duct anatomy during laparoscopic cholecystectomy and the potential use of stapler devices to address such complexities. It aims to assess the safety and efficacy of stapler devices, particularly in cases involving short, and wide cystic duct.
Methodology:
The study, conducted at King Abdulaziz Medical City in Riyadh, Saudi Arabia, between 2021 and 2023. The study design involved a retrospective cohort approach, and the sample size encompassed all cases meeting the inclusion criteria during the study period. Data was analyzed using SPSS program.
Results
The study involving 568 patients, with the predominant technique for ligation being clipping (89.3%). The primary indication for using the Endo GIA stapler was a wide cystic duct (6.2%). Analysis revealed a significant association between stapler device use and hypertension (p = 0.042), diabetes (p = 0.001), CKD (p = 0.011), and obstructive jaundice (p = 0.006). Multivariate regression demonstrated that older patients were 2.1 times more likely to use stapler devices (AOR = 2.125; p = 0.039), while those with obstructive jaundice had a 2.2 times higher likelihood (AOR = 2.168; p = 0.049).
Discussion
Throughout the years, metal clips have shown the best prognosis compared to any other method for securing the cystic duct during closure in laparoscopic cholecystectomy. However, to avoid incomplete sealing of wide, short, or inflamed ducts, other instruments have emerged as possible alternatives for such conditions.
Conclusion
Use of Endo-GIA is a safe and effective method for patients with wide, short cystic duct. Selective usage of endo-GIA is considered cost effective and may add a positive impact in decreasing post operative biliary leak.

Published: August 2024

Abstract

Purpose
Approximately 1 in 5 newly diagnosed cancer patients are between the typical childrearing ages of 20 and 54. As such, a significant portion of cancer patients are also parents to young children (age < 18). This study aims to characterize the need for childcare support for cancer patients from the perspective of healthcare professionals providing care at a major Canadian cancer center.
Methods
Healthcare providers (HCP) were invited to partake in semi-structured telephone interviews, which were conducted using an interview guide. The interviews explored what specific benefits supportive childcare interventions could offer, as well as what might constitute optimal delivery. Interview transcript data was interpreted using thematic analysis.
Results
In total, 28 HCPs participated in interviews between April and May 2022. A wide range of providers were engaged, including physicians, nurses, and allied health professionals. Providers indicated that the introduction of supportive childcare services could have benefits including reduced stress for their patients, improved system efficiency and treatment compliance, and reduction of provider burnout.
Conclusion
These findings indicate that childcare issues are perceived by HCPs as a source of stress for cancer patients with children, and that benefits may be associated with the introduction of supportive childcare services. As such, cancer centers could consider the implementation of such services as a way of providing patient-centered care.

Abstract

A pioneer investigation about ground beetles was carried out within the forest of Mount Nacolod, a protected forest in Silago, Southern Leyte, Philippines. A comprehensive collection effort done for two months yielded a total of 2,315 individuals representing 26 species across 16 genera, 8 tribes, and 2 subfamilies were documented in the forests of Mount Nacolod. Table 1 provides a comprehensive list of these species, detailing their geographical distribution, habitat type, and conservation status. Among the recorded species, 11 are identified as Philippine endemics, with 4 specifically endemic to Leyte. These findings offer baseline data on the carabid beetles of Mount Nacolod. Notably, species such as Pheropsophus hassenteufeli, Pheropsophus lumawigi, and Tricondyla aptera punctipennis were recorded as the most abundant. emphasizing the significance of this study in expanding the understanding of local biodiversity. New additions in Leyte are Brachinus leytensis, Trigonotoma goeltenbothi, Pheropsophus lumawigi, Pheropsophus azoulayi, Pheropsophus uliweberi, and Pheropsophus taclobanensis. The last two species were discovered and identified in this study. The ecological characteristics, distribution, and occurrence of these species were also documented. Urgent conservation efforts are recommended, particularly for rare and endemic carabid beetle species found in specific forest habitats like Mount Nacolod. It is imperative to enhance protective measures in designated landscapes to mitigate threats such as mining, illegal logging, slash-and-burn agriculture, and human encroachment, safeguarding the biodiversity-rich ecosystems of Mount Nacolod and its surrounding forests.

Abstract

Early and precise assessment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is crucial for the clinical management of COPD patients. Soluble suppression of tumorigenicity 2 (sST2) has been observed to increase in inflammatory lung diseases. This study aimed to investigate whether sST2 could serve as a biomarker for AECOPD and predict disease severity. We investigated 55 AECOPD patients, 30 stable COPD patients, and 33 healthy controls. COPD patients had higher sST2 levels than healthy controls. Additionally, sST2 levels showed significant differences among AECOPD patients with different GOLD classes and levels of deterioration, and were significantly correlated with inflammatory markers and pulmonary function tests in these patients. Multivariate logistic regression analyses showed that sST2 was an independent risk factor for AECOPD patients. AECOPD patients with bacterial infection also had significantly higher sST2 levels than those with non-bacterial infection. The performance of sST2 in differentiating AECOPD patients from those with a 4-week stable condition, as well as AECOPD patients with bacterial infection, surpasses that of CRP and PCT. In conclusion, our result suggests that sST2 may serve as a biomarker to predict AECOPD and disease severity, and assist in differentiating bacterial exacerbations in COPD patients.

Abstract

To analyze the genotype distribution of human papillomavirus (HPV) infection in women in the Huizhou region of China and determine its correlation with age and degree of cervical lesions, with the aim to understand the characteristics of HPV infection in women in the region. A total of 65,127 patients who underwent HPV testing at the Second Maternal and Child Health Hospital of Huizhou City from January 2018 to December 2022 were selected as the research subjects. The polymerase chain reaction-reverse dot hybridization technique was used to detect HPV genotypes. The total detection rate of HPV infection was 7.25%, with single infection accounting for 70.94%. The detection rate of high-risk HPV was 6.73%. The top four high-risk types of HPV detected were 16, 52, 18, and 58. The distribution of HPV infection varied greatly among different age groups. The positive rates of HPV were the highest in the < 30-year-old group, followed by the ≥ 60-year-old group, showing a clear bimodal phenomenon. HPV infection in the population of Huizhou is mainly single infection and high-risk type, with higher infection rates in people < 30 and ≥ 60 years old. The local area should pay attention to the prevention and control of HPV.

Published: August 2024

Abstract

In the field of millimeter-wave (MMW) imaging, the integration of artificial intelligence (AI) has emerged as a crucial solution for addressing automation challenges. In this study, concealed object classification was successfully achieved on point cloud data from MMW radar high-precision imaging using the PointNet + + deep learning method. The utilized dataset comprises point cloud data generated through the transformation of 3D models and reconstruction of physical objects with an accuracy of less than 1mm via MMW radar scanning. Classification accuracy was significantly improved by introducing data enhancement techniques, including the generation of homologous data and optimization of sampling points. After several evaluations, 300 epochs of training were conducted using 8192 sampling points, the results showed an accuracy of 0.998 for the training dataset and 0.996 for the test dataset. Moreover, evaluations of samples not included in the original dataset as well as multi-surface scans of concealed objects within the cardboard both resulted in correct predictions, which further validates the effectiveness and reliability of the study and demonstrates the potential of AI applied to MMW imaging.

Abstract

Background: During the COVID-19 pandemic it was not possible to offer face-to-face accompaniment to patients and families, so alternatives had to be sought to alleviate the stressful situations that patients and families were experiencing and for that reason starting to use the New technologies.
Objective: explore the perceived usefulness of New Technologies for volunteering of all the stakeholders. Also we analyse the relationship between the perceived usefulness and technological profile of the participants.
Design: Acceptability study with mixed methodology to analyse and identify the opinion. Transverse descriptive design for quantitative variables and a phenomenological approach for qualitative data describing and explaining the perceived usefulness of New Technologies.
Methods: Patients, relatives, professionals and volunteers from different settings were selected. We evaluated the degree of agreement with the use of New Technologies for volunteering, benefits, disadvantages and satisfaction with volunteering. For qualitative study, we use an open question format to further explore the perceived usefulness of use of New Technologies during Palliative Care volunteering and the technological profile was measured by TechPH.
Results: 402 people participated in this study. Sample was divided into 4 different profiles: patients, relatives, professionals and volunteers. About usefulness, 50% (25/50) of patients, 63.6% (28/45) of relatives, 77.8% (88/136) of professionals and 78.2% (129/171) of volunteers considered New Technologies to be beneficial for volunteering. Three themes about the perceived usefulness of New Technologies for volunteering in Palliative Care were addressed form the qualitative analysis: Difficulties in the use of New Technologies, Benefits and Training for volunteers.
Conclusions: All groups perceived the new technologies to be a useful tool for volunteers’ accompaniment. This perceived usefulness is higher for professionals however they are the group less implicate in this accompaniment. The perceived usefulness is lower in the patient group. They prefer a mix model using New Technologies as a complement of in-person accompaniment.

Published: August 2024

Abstract

The research paper discusses the characterization of aggregate interference distribution for large-scale wireless communication networks. The paper proposes an innovative approach to estimate the probability density function of the aggregate interference in the wireless network by using statistical modeling techniques. The methodology involves using a DS-CDMA communication system that captures aggregate interference in large-scale wireless networks, considering factors like path loss, shadowing, fading, and spatial distribution of interfering nodes. It was unearthed that the interference of the large-scale wireless network was alpha-stable probability density function (pdf) of Weibull distribution, which belongs to the class of heavy-tailed probability distributions. Experimental results from simulations on large-scale wireless communication networks using Matlab 20021a were used to validate the effectiveness and accuracy of the proposed approach, demonstrating the reliability of the statistical modeling technique. The alpha-stable pdf model assist network designers and engineers in gaining valuable insights into aggregate interference characterization and to make informed decisions to optimize network performance.

Abstract

Despite significant strides in economic development, India continues to face challenges in ensuring improved nutritional outcomes for its children. This situation underscores the urgent need to address a pervasive issue that threatens the health and future potential of the country's younger generation. The nutritional status of underfive children in the northeastern states of India was examined in this study using data from the latest rounds of the National Family Health Survey (NFHS) conducted between 2019 and 2021. This study investigated the trends in the prevalence of stunting, wasting, and underweight among children, highlighting disparities across states and socioeconomic groups. Multivariate logistic regression analysis identified significant determinants of childhood malnutrition, including demographic and socioeconomic factors. Additionally, the study evaluated inequality in undernutrition using concentration indices based on wealth and maternal education. These findings underscore the urgent need for targeted interventions to address childhood malnutrition in the region, emphasizing the importance of socioeconomic factors in shaping nutritional outcomes. Policy implications include targeted efforts to improve maternal education, enhance access to healthcare facilities, and address socioeconomic inequalities to mitigate the prevalence of undernutrition in the northeastern states of India. Overall, this research emphasizes evidence-based policies and interventions aimed at reducing undernutrition and improving child health outcomes in the northeastern states of India.
