ABSTRACT

Schistosomiasis in Indonesia is caused by the trematode worm S. japonicum, with the snail Oncomelania hupensis lindoensis as the intermediate host. To eliminate schistosomiasis by 2020, cross-sectoral schistosomiasis control is carried out, including implementing environmental management based on the results of mapping the focus areas. This study aimed to determine whether there was a decrease in foci and infection rates in snails with comprehensive cross-sectoral schistosomiasis control activities in the pilot village. This study used a cross-sectional design conducted in six schistosomiasis endemic areas. The results showed that snail density, infection rate, and the number of focus areas decreased after the inter-sectoral intervention. The prevalence of schistosomiasis in snails varied; in some focus areas, the prevalence of schistosomiasis in snails decreased after the intervention, but in some focus areas, the prevalence of snails did not decrease.

Published: December 2022

Foreign body (FB) aspiration remains a serious health problem, particularly in children. The complications due to occlusion by FB or related to procedures for removal can lead to morbidity and mortality. Most of the FBs are located in the unilateral bronchus, however, the organic FB can be multiple or bilaterally located when children chewed the FB. Here, we present a case of successful retrieval of bilateral bronchial FBs. Preoperatively, FB in the left main bronchus was diagnosed, however, FB of the right upper bronchus was not definitive on X-ray and CT scan. During the rigid bronchoscopy, occult FB in the right upper bronchus was detected and successfully removed.

Published: December 2022

Integrating biological material within soft microfluidic systems made of
hydrogels offers countless possibilities in biomedical research to
overcome the intrinsic limitations of traditional microfluidics based on
solid, non-biodegradable, and non-biocompatible materials.
Hydrogel-based microfluidic technologies have the potential to transform
in vitro cell/tissue culture and modeling. However, most hydrogel-based
microfluidic platforms are associated with device deformation, poor
structural definition, reduced stability/reproducibility due to
swelling, and a limited range in rigidity, which threatens their
applicability. Herein, we describe a new methodological approach for
developing a soft cell-laden microfluidic device based on
enzymatically-crosslinked silk fibroin (eSF) hydrogels. Its unique
mechano-chemical properties and high structural fidelity, make this
platform especially suited for in vitro disease modelling, as
demonstrated by reproducing the native dynamic 3D microenvironment of
colorectal cancer and its response to chemotherapeutics. Results show
that 14 wt% enzymatically-crosslinked silk fibroin microfluidic
platform has outstanding structural stability and the ability to perfuse
fluid while displaying in vivo-like biological responses. Overall, this
work shows how the combination of enzymatically-crosslinked silk fibroin
and microfluidics can be employed for developing soft lab-on-a-chip
platforms with superior performance.

Published: December 2022

Background: We assessed whether the association between the
risk of cerebrospinal fluid escape (CVE) and specific antiretroviral
(ARV) classes, such as protease inhibitors, is due to suboptimal
pharmacological profile generated by archived resistance-associated
mutations (RAMs). Methods: A retrospective multicentric study
on 300 adult people with HIV on antiretroviral therapy (ART) and
available historical plasma genotype resistance testing (HGRT) for
reverse transcriptase (RT) and protease genes between 2001 and 2021. The
odds ratio for demographic, clinic-, and ART-related variables and CVE
was estimated by multivariable modelling. HGRT-adjusted central nervous
system effectiveness penetration (CPE) score was computed in modelling
the risk. Results: Median age, plasma VL, and CD4 count were 49
years, <50 copies/mL, and 310 cells/μL. CVE was detected in 51
participants (17.0%). No difference in CVE prevalence was observed
according to ART type, number of ARVs or ARV classes. Participants with
CVE had more frequently plasma (52.9% vs 32.1%, p=0.005) and CSF RAMs
in RT (n=63, 57.1% vs 28.6%, p=0.029), but not in protease gene. The
presence of plasma RAMs in RT associated with increased odds of CVE in
adjusted analyses (aOR 3.9, p<0.001) and in models restricted
to plasma viral load ≤50 copies/mL (n=202; aOR 4.3 , p=0.003).
CVE risk decreased by 40% per each point increase in HGRT-adjusted CPE
score in multivariable models (p<0.001). Conclusions:
Viruses harboring mutations appear to favor CVE and the impact of single
ARV classes or type of ART regimens may lose significance when adjusted
for the presence and effect of specific RAMs.

Authors: Kim Jinhee , Kang Nam-Hun , Bae Jong-Myon
Published: December 2022

In 2021, the incidence of newly notified tuberculosis in Jeju Province decreased by 23.0% compared to that in the previous year. This was the largest decline among the 18 municipalities studied. This study aimed to examine trends in the incidence of tuberculosis among different age and sex groups in Jeju Province between 2017 and 2021. This study observed the number of new cases in the annual report from 2017 to 2021, published by the Jeju Center for Infectious Diseases Control and Prevention. The average annual percentage change (AAPC; %) was calculated to determine the trend in crude incidence rates over the past 5 years by sex and age. While a P-value of <0.1 was considered marginally significant, a P-value of <0.05 was considered statistically significant. The AAPC of all age groups in Jeju Province had negative values. In men, there was a statistically significant decrease in ages 30-34, 40-44, 45-49, and 50-54 years and a marginally significant decrease in ages 35-59, 55-59, 60-64, 65-69, 75-79, and ≥80 years. In women, a statistically significant decrease was observed among patients aged 30-34, 35-39, and ≥80 years, and a marginally significant decrease was observed among patients aged 45-49, 50-54, 60-64, 65-69, and 75-79 years. A statistically significant decrease in tuberculosis was observed among patients in their 30s and 40s, and elderly patients aged ≥80 years comprised the group vulnerable to tuberculosis. Based on these findings, tuberculosis prevention and screening programs conducted in Jeju Province were effective.

Published: December 2022

This case report describes a case of isolated (not associated with other anomalies) lower vaginal hypoplasia complicated by megalourethra (urethral dilatation) due to frequent urethral sexual intercourse in a regularly menstruating (hypomenorrheic) woman. The patient was a 24-year-old woman who underwent transperineal ultrasonography as well as magnetic resonance imaging followed by sequential cystoscopic and vaginoscopic examinations. Finally, a pull-through procedure was used to create a new vagina. The main outcome measure was patent vagina formation. The procedure successfully corrected isolated lower vaginal hypoplasia. The postoperative course was smooth, with the restoration of regular intercourse in the correct location. It was concluded that all gynecologists should have increased awareness of rare female genital anomalies to avoid serious sequelae, particularly in newly married patients.
Food allergy
Authors: Lee Jaechun , Kim Cheol-Woo
Published: December 2022

Food allergy is one of the adverse food reactions, which is developed by immunological reactions. Food allergy is increasing in prevalence among children and adults. In the diagnosis, food challenge is confirmative with history and laboratory tests. Avoidance of culprit food is the only preventive method, especially in patients with severe symptoms. In some food allergies, crossreactivity among allergens should be considered. Latex-fruit/vegetable syndrome and pollen food allergy syndrome are well-understood phenotypes of food allergy related to cross reaction. Red meat allergy is recently described as one of tick-borne diseases. In a rare phenotype of food-dependent exercise-induced anaphylaxis, factors affecting the absorption of food allergen are important in its pathophysiology.

Published: December 2022

This work evaluated the process for heptaldehyde, undecylenic acid, and methyl undecenoate production from castor oil, methyl ester of castor oil, and ricinoleic acid. Experiments were performed in a continuous pilot-plant scale pyrolysis reactor. Those are very important green chemical products that the thermal cracking of castor oil might produce. Transesterification of castor oil produces methyl ricinoleate, and its thermal cracking generates methyl undecenoate and heptaldehyde. The pyrolysis temperatures tested were 530?C, 545?C, 560?C, and 575?C, with residence time from 17 s to 32 s and mass flow at 400 g/h of the mixture of materials with 25% distilled water. It was observed that the temperature influenced the bio-oil yield in different degree for each material. The bio-oil was characterized by iodine index, acid number, and mass, and the contents of its compounds were obtained by GC-FID chromatography. The best result for the undecylenic acid mass yield of the desired compounds occurred at 530?C, achieving 17.8% from ricinoleic acid and 16.5% from castor oil. For the heptaldehyde, the highest production was also obtained at 530?C, with a value of 20.7% from methyl ester and 15.2% from ricinoleic acid.

Published: December 2022

Introduction/Objective Hemophagocytic lymphohistiocytosis (HLH) is a severe hyperinflammatory condition characterized by fever, splenomegaly, and cytopenias. Diagnosis of HLH requires at least five of the eight criteria set by the Histiocyte Society and poses a significant challenge to physicians. HLH-2004 criteria include measurement of plasma levels of soluble receptor for interleukin-2 (sIL-2R), an invaluable tool in the diagnosis of HLH, particularly because it can be measured swiftly and inexpensively. Methods We retrospectively analyzed medical records of 45 pediatric patients (28 boys and 17 girls, median age 8.1 years) who were investigated for suspected HLH in University Children?s Hospital in Belgrade, during the period from 2012 to 2022. Results Ten children were diagnosed with HLH, while 35 did not have HLH. All 10 HLH patients had secondary HLH: eight suffered from infection or inflammatory condition, one from an autoimmune disease, and one from malignancy. Level of sIL-2R was above the HLH-2004 cutoff value of 2400 IU/ml in 9/10 patients with HLH (sensitivity 90%) and 9/35 of patients who did not have HLH (specificity 74.2%). Conclusion Soluble IL-2 receptor measurement is valuable in children suspected to have HLH. Sensitivity and specificity of this analysis can be further improved by strict patient selection and a comprehensive diagnostic approach.

OBJECTIVE

To project the prevalence and number of youths with diabetes and trends in racial and ethnic disparities in the U.S. through 2060.

RESEARCH DESIGN AND METHODS

Based on a mathematical model and data from the SEARCH for Diabetes in Youth study for calendar years 2002–2017, we projected the future prevalence of type 1 and type 2 diabetes among youth aged <20 years while considering different scenarios of future trends in incidence.

RESULTS

The number of youths with diabetes will increase from 213,000 (95% CI 209,000; 218,000) (type 1 diabetes 185,000, type 2 diabetes 28,000) in 2017 to 239,000 (95% CI 209,000; 282,000) (type 1 diabetes 191,000, type 2 diabetes 48,000) in 2060 if the incidence remains constant as observed in 2017. Corresponding relative increases were 3% (95% CI −9%; 21%) for type 1 diabetes and 69% (95% CI 43%; 109%) for type 2 diabetes. Assuming that increasing trends in incidence observed between 2002 and 2017 continue, the projected number of youths with diabetes will be 526,000 (95% CI 335,000; 893,000) (type 1 diabetes 306,000, type 2 diabetes 220,000). Corresponding relative increases would be 65% (95% CI 12%; 158%) for type 1 diabetes and 673% (95% CI 362%; 1,341%) for type 2 diabetes. In both scenarios, substantial widening of racial and ethnic disparities in type 2 diabetes prevalence are expected, with the highest prevalence among non-Hispanic Black youth.

CONCLUSIONS

The number of youths with diabetes in the U.S. is likely to substantially increase in future decades, which emphasizes the need for prevention to attenuate this trend.

A Comprehensive Study on the Effects of Noise Abatement Departure Procedures on Noise Contours Around Tan Son Nhat International Airport
Authors: Kiet La Tuan , Tran Tien Anh
Published: December 2022

In recent years, accompanied by economic growth, air transportation in Vietnam has rapidly risen with the introduction of many new airlines. This situation has led to an increase in aircraft movement frequency flying in and out of the airports and raised concerns about the effects of increased noise exposure levels on public health and the natural environment in the vicinity of the airports. Vietnam authority has also issued several documents to regulate the establishment of the noise contour maps to evaluate the current noise exposure levels around airports in Vietnam and recognized the noise problem in aviation as a significant issue. One of four measures to reduce the noise around airports introduced in the Balanced Approach to Noise Management of the International Civil Aviation Organization is noise abatement operational procedures. This research is one of the first attempts to provide a comprehensive study on predicting the noise levels and establishing noise contour maps around Tan Son Nhat International airport with the assumption that aircraft take-off following the noise abatement departure procedures 1 and 2 using MATLAB software. The computed noise contours for both procedures show that the day-evening-night equivalent noise levels range from 45 dB(A) to 60 dB(A) around the airport, with the difference in noise levels between the two procedures primarily occurring at the end of the runway due to the difference in stepped departures. These results provide a reference for the authorities to study further in applying suitable noise reduction plans in the vicinity of airports.
Aircraft Noise Compatibility of the Airports with Progress of Noise Reduction at Source

Published: December 2022

Сreation of noise exposure maps and airport noise compatibility programs are the basic steps in aircraft noise exposure and impact management in/around the airports, both of them are fundamental for aircraft noise zoning procedures. Noise reduction at source is also a strategic element of this management, and efficient implementation of quieter aircraft designs in operation provides closer distances of the boundaries of noise zones prohibited for residences to runway axis. These new conditions oblige the decision-makers, responsible for noise management, to be stricter with procedures for noise zones definition and to include in consideration a number of new acoustic sources inside the aerodrome besides the aircraft in flight operation, which may influence the overall exposure and impact of noise on population living or/and acting around the airport. In other words, current noise exposure maps and airport noise compatibility programs must include these dominant noise sources at specific locations of the airport also, not only the flight noise sources, as it was enough before. Today such essential noise sources for consideration in airport noise management are the aircraft in maintenance and overhaul and the aircraft during the taxing between the runway and stands on apron first of all, especially if their locations are quite far from aircraft flight operation routes and close to the residential areas around the aerodrome. The noise maps are required to be calculated currently, as for aircraft operation, so as for their maintenance and overhaul, but the measurements are evident also for their confidence and accuracy purposes.

Published: December 2022

Tambak udang merupakan salah satu budidaya air tawar yang banyak dijumpai di berbagai wilayah di Indonesia. Proses pembudidayaan udang diberi pakan dan diawasi pertumbuhannya. Saat masa panen, ketika udang sudah berumur 101-104 hari dengan bobot rata-rata berkisar antara 21,85-22,70 gram dan ukuran udang berkisar 44-45 ekor/kg. Sebelum masa panen, kontrol pakan udang sangat penting demi menjaga pertumbuhan udang. Pembudidaya biasanya melakukan monitoring pertumbuhan udang dengan mengukur berat udang secara manual, yaitu dengan mengangkat udang ke permukaan menggunakan anco (jaring udang) dan mengambil udang tersebut kemudian ditimbang menggunakan timbangan manual, hal tersebut dirasa kurang efektif. Oleh sebab itu, pembudidaya beralih menggunakan alat ukur berat udang, yaitu memanfaatkan metode deteksi objek dan sensor berat. Alat ini bekerja dengan mengambil sampel udang dan dilakukan secara berkala dengan kurun waktu yang sama, selanjutnya akan mendeteksi sampel jumlah udang dan menimbang rata-rata berat udang. Sehingga pembudidaya dapat memberi pakan udang dengan jumlah yang tepat. Alat ini menampilkan data sampling berat udang.

Introduction: Outdoor parking lots have been a common and cost-effective solution for private mobility in European social housing districts built between the 1960s and 1980s, but this solution has significant, particularly environmental and spatial, impacts. The future of urban mobility requires changes to an electrified community model, based on shared vehicle fleets. Purpose of the study: We aimed to analyze the transport, social, and environmental improvements of a smart multi-functional micro-hub for neighborhoods — a theoretical proposal designed to facilitate the transition toward a decarbonized city. Methods: The literature is therefore reviewed and a case study of the city of Malaga is provided. Results: On the one hand, the findings show the environmental, economic, and spatial advantages of this model compared to traditional underground parking lots. On the other hand, the paper proposes the design characteristics that could be adopted by a particular type of buildings and their urban space. Finally, the paper discusses the implications of setting up a citywide network of micro-hubs and the ensuing benefits.
ANALYSIS OF COOLING SYSTEM EFFICIENCY
Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Dmitriev Yuri
Published: December 2022

Introduction: The main task of cooling systems in the machine room of a data center is to maintain optimal air parameters at the inlet to IT equipment in accordance with the applicable regulatory documents. If the value of air temperature at the inlet to IT equipment exceeds the optimal value, then so-called hot spots occur — the operation of IT equipment in such places can lead to its overheating and failure. The main reason for the occurrence of hot spots is the violation of air circulation between the hot and cold aisles. Purpose of the study: We aimed to analyze the influence of different methods of hot aisle isolation on the efficiency of IT equipment cooling. Methods: We performed modeling of different methods of hot aisle isolation at different capacity values of IT equipment in the STAR-CCM+ program. Result: As a result of studying temperature and air conditions in a data center, we found the most rational way of isolating the hot aisle — top horizontal containments with vertical blind panels in the free rack space.

Introduction: The service life of reinforced-concrete structures can be increased with the use of effective repair compositions obtained by activating the original components. Purpose of the study: We aimed to develop effective repair compounds obtained by activating the original components. Methods: To process the original components, low-temperature non-equilibrium plasma (LTNP) and electromagnetic activation in a vortex layer device were used. In the course of the study, we used polypropylene, steel, glass, and basalt fiber and fiber made of structured ferromagnetic microwire. Electron microscopy and X-ray diffraction analysis were applied. Results: It was established that the combined use of the above methods for the modification of raw components makes it possible to improve the strength of these materials by more than 50%, which is due to the characteristics of structure formation in the developed compositions. For instance, LTNP increases the amount of portlandite and reduces the main phases of cement stone— C3S and β-C2S, and vortex activation contributes to an increase in the total number of crystalline phases. Quartz powder particles processed in an electromagnetic mill are characterized by layered structure, high surface roughness, large developed cracking, as well as inclusions as a result of impact action. All that improves the physical and mechanical properties of the resulting repair compositions by an average of 20%. Repair compositions additionally treated with plasma modification feature new hydrated formations on quartz grains.
Costs and Coping Strategies of Tuberculosis Inpatients in Tertiary Care Hospital Settings in Lahore, Pakistan

Background: Despite free treatment and screening programs, Tuberculosis can reduce the working capability of patients due to the costs they incur. Eventually, it can lead to economic crises in low- and middle-income countries with a high prevalence of Tuberculosis. The objectives were to look into the costs incurred by Tuberculosis patients and to determine the coping strategies they adopted while admitted to the Hospitals for treatment of Tuberculosis.
Methods: In this cross-sectional study, data was collected using an adapted questionnaire based on World Health Organization’s TB patient cost survey protocol. The study was conducted in two tertiary care hospitals in Lahore from November to December 2019. In all 309 TB patients admitted in these hospitals were administered the questionnaire. The data was analyzed with SPSS version 23 software.
Results: The estimated direct medical costs per TB patient were 42,106.7 Pakistani Rupees ($271.65). Indirect costs per patient were double of this i.e. 76,013.4 Pakistani Rupees ($490.40). About 65.3 % of patients suffered Catastrophic Health Expenditure with a significant difference between the household income before and during TB treatment. About 52.10% of total patients borrowed money from others and 28.76% sold their assets for meeting the costs incurred.
Conclusion: Disparities in household income and treatment total costs lead to a decrease in financial risk protection of TB inpatients. A multi-sectoral approach may help cope with the costs of patients and increase the knowledge of newly diagnosed TB patients to decrease the incidence and achieve the END TB goals by 2035.

The digital image is one of the discoveries that play an important role in various aspects of modern human life. These findings are useful in various fields, including defense (military and non-military), security, health, education, and others. In practice, the image acquisition process often suffers from problems, both in the process of capturing and transmitting images. Among the problems is the appearance of noise which results in the degradation of information in the image and thus disrupts further processes of image processing. One type of noise that damages digital images is salt and pepper noise which randomly changes the pixel values to 0 (black) or 255 (white). Researchers have proposed several methods to deal with this type of noise, including median filter, adaptive mean filter, switching median filter, modified decision based unsymmetric trimmed median filter, and different applied median filter. However, this method suffers from a decrease in performance when applied to images with high-intensity noise. Therefore, in this research, a new filtering method is proposed that can improve the image by randomly exploring pixels, then collecting the surrounding pixel data from the processed pixels (kernel). The kernel will be enlarged if there are no free-noise pixels in the kernel. Furthermore, the damaged pixels will be replaced using the mean data centering statistic. Images enhanced using the proposed method have better quality than the previous methods, both quantitatively (SSIM and PSNR) and qualitatively.
