Published: November 2024

Hyperglycemia can be experienced by corona virus disease (COVID-19) patients due to the invasion of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) into pancreatic cells or other mechanisms such as insulin resistance, counter-regulatory, stress induction, and glucocorticoid therapy. Hyperglycemia can stimulate the production of reactive oxygen species (ROS) and pro-inflammatory cytokines leading to an increase in the disease severity. Based on the clinical and laboratory criteria, the severity of COVID-19 patients is classified into asymptomatic, mild, moderate, severe, and critical. This study aimed to investigate the association between blood glucose levels at admission and the severity of COVID-19 patients with and without diabetes mellitus (DM). It was a cross-sectional study using secondary data from COVID-19 patients in Pondok Kopi Jakarta Islamic Hospital from April to June 2021. This study involved 340 patients with comorbid DM (n=78) and without comorbid DM (n=262). The Mann-Whitney and Spearman correlation test were used. A significant difference between random blood glucose levels in comorbid DM patients and patients without comorbid DM (p<0.05). However, there is a weak correlation between random blood glucose levels and severity with comorbid DM (r=0.112) and without comorbid DM (r=0.129). In conclusion, a positive and weak correlation between blood glucose levels at admission and the severity of COVID-19. The severity increases as the blood sugar level increases. Further study needs to be performed considering other comorbid conditions.

Anatomical and physiological changes occur along with the aging process. One of the changes is decreased flexibility due to changes in the musculoskeletal system. Upper and lower limb flexibility is closely related to the ability to carry out daily activities, which affects the quality of life of the elderly. Surya Namaskar yoga is known to help increase flexibility because it integrates stretching components within its movement. This study aimed to investigate the effect of Surya Namaskar on flexibility in the pre-elderly and elderly. It was is quasi-experimental study with a pre-experimental one-group pretest-posttest research design. A total of 20 participants were selected using consecutive sampling according to the inclusion criteria. Flexibility measurements of the upper and lower limbs were carried out before and after the intervention using the back scratch test and chair sit and reach test methods. Surya Namaskar intervention was carried out for 8 wk. Data were analyzed using the Shapiro-Wilk normality test, paired t-test, and Wilcoxon test. The results showed that there was a highly significant difference between the mean value of the back-scratch test (for upper limb flexibility) before and after the intervention (p<0.001). Significant differences were also found in the mean values of chair-sit-and-reach test measurements (for lower extremity flexibility) before and after the intervention (p<0.001). In conclusion, Surya Namaskar exercises can improve the flexibility of the upper and lower extremities in the pre-elderly and elderly.

The older adult often experiences a low-grade chronic inflammation that commonly manifests in various conditions without infection, including hypertension. The serum neutrophil-to-lymphocyte ratio (NLR) and hyperuricemia are important markers for various diseases including hypertension. Older adult accounts for 17.33% of the total population of Yogyakarta Special Province, which is the highest compared to other provinces. The study aimed to evaluate the relationship between NLR and hyperuricemia with hypertension among adult patients in Sleman District, Yogyakarta, Indonesia. It was a community-based cross-sectional nested study involving 90 older adults aged ≥70 y.o. living around of the Sleman Health and Demographic Surveillance System (HDSS). Data of demographic and health characteristics of the subjects were collected. Independent t test, and Mann Whitney test were used to analyze mean differences between normotensive and hypertensive groups. Multivariate analysis with logistic regression was used to analyze correlation between all variables. The results showed 59 respondents (65%) suffered from hypertension and 31 (35%) respondents had normal and pre-hypertension. No significantly different in almost of the subject characteristics between the normotensive and the hypertensive groups was observed (p>0.05). However, significantly different between the normotensive group and the hypertensive group was observed in the history of hypertension, blood pressure/BP, mean arterial pressure/MAP, abdominal circumstance/AC, fasting blood glucose/FBG, triglyceride, and hemoglobin (p<0.05). No significantly different in the NLR and HsCRP levels of the normotensive group compared to the hypertensive groups were observed (p>0.05). However, the uric acid level of the hypertensive group [5.6 (2.9-9.4 mg/dL)] was significantly higher than that the normotensive group [4.7 (2.9-8.0 mg/dL)] (p=0.042), although it was no significantly relationship with hypertension (p>0.05). In conclusion, there is no relationship between NLR, HsCRP and uric acid with hypertension among middle old and oldest old in Sleman District.

Herlyn-Werner-Wunderlich (HWW) syndrome is a very rare female congenital anomaly of urogenital tract. The definite etiology of HWW syndrome is still unknown. It may be caused by the abnormal development of Mullerian and Wolffian ducts. The characteristic triad of this syndrome includes didelphys uterus, obstructed hemivagina, and ipsilateral renal agenesis, recently known as Obstructed Hemivagina and Ipsilateral Renal Anomaly (OHVIRA) syndrome. A 17 y.o. presented with intermittent lower abdominal pain. Physical examination revealed in normal limit. From the ultrasonography examination, it was found uterus didelphys with left hemiuterus hematomethra, hematocolpos, with normal anatomy and function of the right kidney, but there was no left kidney. From pelvic magnetic resonance imaging (MRI) and laparoscopy showing a complete duplication of the uterus from the horn to the cervix with no connection between the two uterine cavities. Both ovaries were normal. The right fallopian tube was normal. The left tube was enlarged, attached to the uterus and the left ovary. No left kidney was found. From the previous surgery, there was a misdiagnosed with brown cyst. Physical examination such as rectal toucher often missed, regardless it can be used to determine some differential diagnosis. MRI is most accurate for providing details regarding the altered anatomy and for identifying associated hematocolpos, hematosalping or hematometra for HWW syndrome cases. The laparoscopy guiding diagnostic and operative management of the vaginal septectomy procedure was performed. In conclusion, misdiagnosis of HWW syndrome can be occurred on ultrasound examination. MRI is an examination that is considered appropriate to help confirm the diagnosis. Laparoscopy can be used with the aim of establishing a diagnosis or in surgical management, in this case, a septectomy is performed.

Abstract

The evolution of networking technologies has enabled us to connect devices, people, things, and infrastructures. This has promoted urban development by enabling technologies for building smart cities. The scope for developing more featured applications has got a boom in the IT industries. Enabling technologies like Wi-Fi had an integral role in smart cities with their advanced features and low cost of implementation. To cope with the user requirements and technological changes IEEE 802.11 standard for Wi-Fi timely introduces new amendments. The increasing complexity of the latest amendments with a wide range of rates leads rate selection to a difficult task. The IEEE 802.11 standards did not specify any methods for rate selection. Researchers have come up with different rate selection algorithms to resolve this problem. However, the complex nature, huge time consumption, and real time implementation difficulties make it less effective. This paper proposes a rate adaptation algorithm based on smart usage of block-acknowledgment and signal strength. Simulation result from NS3 shows that the proposed rate adaptation method improves the performance, based on packet delivery ratio, delay, and throughput compared with the recent RaCA algorithm.

Abstract

With the continuous application of Internet of Things (IoT) technology, cluster-based wireless sensor networks have been the popular solutions for energy saving. However, it commonly faces the challenge of hot spot problem. Hence, designing an efficient and energy-conserving routing strategy for networks is crucial. Static base stations consume considerable energy in routing. Therefore, this paper proposes a cluster routing protocol integrating a mobile sink, aiming to achieve a balanced distribution of energy consumption and maximize network lifetime. Initially, a weighted function is designed based on residual energy, inter-node distance, and node centrality to select Cluster Heads (CH). Subsequently,combining Particle Swarm Optimization (PSO) algorithm, paths are planned for the mobile sink (MS) to efficiently traverse and collect data from the CHs. Additionally, Differential Evolution (DE) is incorporated to prevent the algorithm from falling into local optima. Simulation results demonstrate that compared to other algorithms, the proposed approach consumes less energy and extends the network's lifetime.

Published: November 2024

Abstract

Background
Budd-Chiari Syndrome (BCS) caused by Intravenous leiomyomatosis (IVL) is a rare and uncommon. Further reports and thorough evaluation are needed to identify and manage this disease.
Method
We described the case of a 49-year-old lady, exhibiting features of Budd-Chiari syndrome secondary to intravenous leiomyomatosis, and reviewed other three previous cases of BCS caused by IVL.
Results
The mean onset age of these four patients was 54.8 years. All but one (patient No.2) had a history of myoma, myomectomy, or hysterectomy. Abdominal pain, bloating or increasing abdominal birth, and bilateral lower extremity edema were common symptoms. The establishment of clinical diagnoses of IVL and BCS mainly depends on clinical presentations and imaging like ultrasonography, CT (with vascular reconstruction), and magnetic resonance imaging (MRI). Surgical intervention to alleviate the hepatic veins outflow obstruction is the most important treatment.
Conclusions
BCS caused by IVL should be considered when inferior vena cava (IVC) and right atrium (RA) lesions occur in a patient with characteristics of BCS and a history of uterine myoma or hysterectomy. Complete tumor resection with TAHBSO is the only curative treatment and should be performed as soon as possible.

Abstract

The addition of biochar (BC) during composting significantly influences the concentration and chemical structure of dissolved organic matters (DOM), thereby affecting its binding properties with heavy metals (HMs). This study examines the co-composting of chicken manure with varying BC dosages, specifically 0 wt% (CK), 1 wt% (T1), and 2 wt% (T2), and comparatively analyzes the binding characteristics between compost-derived DOM and copper ions (Cu(II)). EEM-PARAFAC analysis identified three primary components in the DOM: fulvic acid-like (C1), humic acid-like (C2), and protein-like (C3) components, each exhibiting distinct Cu(II) binding properties. The complexation constants (logK) for these components with Cu(II) increased with the BC addition, whereas the fraction of bound sites (f values) decreased, indicating that BC-amended compost DOM forms more stable DOM-Cu(II) complexes but with fewer available binding sites. 2D-COS analysis of synchronous fluorescence spectra revealed that the fulvic-like peaks were more sensitive to Cu(II) concentration variations across all DOM types, while humic-like substances exhibited a stronger preference for Cu(II) binding. HPSEC results showed broad molecular weight (MW) distributions (100–300,000 Da) in BC-amended compost DOM, with a significant decrease in medium MW regions (1000-30,000 Da) as Cu(II) concentration increased, suggesting that medium MW DOM fractions are particularly sensitive to Cu(II) binding, leading to higher weight-averaged MW values with increased Cu(II) concentrations. This study provides new insights into how BC addition to compost can influence the binding behavior of DOM with HMs, highlighting its potential for enhancing HMs immobilization in compost-amended soils.

Published: November 2024

Abstract

Background
Osteoarthritis (OA) is characterized by the progressive degeneration of the synovial joint, leading to irreversible damage to articular cartilage and subchondral bone. While animal models have advanced our understanding of OA, numerous unresolved issues still remain. The zebrafish, known for its transparent body, rapid developmental, and impressive regenerative capabilities, offers substantial potential for osteoarthritis research. This study seeks to establish a new OA model utilizing the zebrafish jaw joint, acting as a supplement to traditional animal models. In the future, this model could serve as a valuable platform for delving deeper into the mechanisms of this disease, as well as for advancing drug discovery and therapeutic interventions.
Materials and Results:
Leveraging the skeletal structure of zebrafish, we targeted the largest jaw joint for our research. A custom fixation device was crafted, and a microinjection system was utilized to inject mono-iodoacetate (MIA) or collagenase type II (CTII) into the joint cavity of zebrafish. Subsequent analyses included histological staining, immunohistochemistry, OA research society international (OARSI) scoring, and real-time in vivo imaging were performed at 7, 14, and 28 days post injection. Our results effectively demonstrated the presence of synovial inflammation and cartilage damage within the zebrafish mandible, affirming the feasibility of inducing OA in zebrafish.
Conclusion
In conclusion, the local injection of chemical agents into the joint cavity of zebrafish effectively induced the occurrence of OA. Establishing the zebrafish OA model enhances the array of animal models available for OA research. Moreover, zebrafish present distinct advantages, including robust regenerative abilities, genetic editing simplicity, and efficient drug screening. Consequently, this offers a fresh avenue for investigating the pathogenesis, prevention, and potential therapeutic approaches for human OA.

Abstract

The level of pollution in water bodies has recently increased to a concerning degree due to the expansion of industrial activities. The consumption of organic dyes in textile industries has also set up an alarming situation worldwide for their side-effects. These pigments are typically persistent and challenging for traditional wastewater treatment methods to break them down. The present study reports a novel, rapid, and green method for the synthesis of MnO2 nanoparticles using the Withania Somnifera (Ashwagandha) extract. The techniques such as UV-Vis spectroscopy, FESEM, FTIR, EDX were employed to confirm the synthesis of the prepared nanoparticles. Bromocresol green and Bromothymol blue were set up as benchmark for measuring the photocatalytic efficacy of the prepared nanoparticles. It was observed that the prepared nanocatalyst on the sunlight exposure displayed excellent removal effectiveness for both the dyes i.e. 92% for Bromothymol blue and 95% for Bromocresol green respectively for a time period of 1 h. The effect of parameters such as time, dose of photocatalyst, and photodegradation kinetics was also systematically investigated for evaluating the effectiveness of the developed photocatalyst. The developed method is easy to implement, is environment friendly and does not require any chemical agents or sophisticated instrumentation for synthesis. This opens a novel avenue for the development of green photocatalyst which can emerge as an exceptional nanomaterial for the waste water remediation.
Talbot effect-based sensor measuring grating period change in subwavelength range

Published: November 2024

Abstract

Talbot length, the distance between two consecutive self-image planes along the propagation axis for a periodic diffraction object(grating) illuminated by a plane wave, depends on the period of the object and the wavelength of illumination. This property makes the Talbot effect a straightforward technique for measuring the period of a periodic object (grating) by accurately determining theTalbot length for a given illumination wavelength. However, since the Talbot length scale is proportional to the square of the grating period, traditional Talbot techniques face challenges when dealing with smaller grating periods and minor changes in the grating period. Recently, we demonstrated a Fourier transform technique-based Talbot imaging method that allows for controlled Talbot lengths of a periodic object with a constant period and illumination wavelength. Using this method, we successfully measured periods as small as a few micrometers and detected sub-micrometer changes in the periodic object. Furthermore, by measuring the Talbot length of gratings with varying periods imaged through the combination of a thick lens of short focal length and a thin lens of long focal length and large aperture, we determined the effective focal length of the thick lens in close agreement with the theoretical effective focal length of a thick lens in the presence of spherical aberration. These findings establish the Talbot effect as an effective and simple technique for various sensing applications in optics and photonics through the measurement of any physical parameter influencing the Talbot length of a periodic object

Abstract

Objective: This study proposes a novel surgical technique for the excision of benign parotid tumors, utilizing a extracapsular dissection guided by a three dimensional digital model of the facial nerve(3DFN-ECD) and compares its clinical efficacy with the extracapsular dissection (ECD) method.
Methods: This prospective study included 68 patients with benign parotid tumors. The control group (40 patients) received the ECD treatment, while the experimental group (28 patients) , underwent the 3DFN-ECD approach proposed in this study. Preoperative three-dimensional double-echo steady-state water excitation sequence (3D-DESS-WE) of MRI was employed to visualize the tumor and facial nerve, and the Mimics software was used to reconstruct a three-dimensional digital model of the facial nerve and parotid tumor. The surgical incision and facial nerve dissection were planned based on the relationship between the tumor and the facial nerve. Postoperative facial nerve function and aesthetic outcomes of the incisions were compared between the two surgical techniques.
Results: There was no significant difference in the postoperative complications between the two groups. Postoperative facial nerve function scores in the 3DFN-ECD group were significantly higher than those in the control group. The incidence of temporary facial nerve paralysis was significantly lower in the 3DFN-ECD group, and the visual analogue scale score for aesthetic outcomes of the surgical incision was significantly improved.
Conclusion: The novel 3DFN-ECD surgical approach proposed in this study significantly reduces the risk of facial nerve injury and improves the aesthetic outcomes of the parotid tumor surgical incision.
