Published: October 2022

BACKGROUND

For patients with self-harm behaviors, the urge to hurt themselves persists after hospital discharge, leading to costly readmissions and even death. Hence, postdischarge intervention programs that reduce self-harm behavior among patients should be part of a cogent community mental health care policy.

OBJECTIVE

We aimed to determine whether a combination of a self-help mobile app and volunteer support could complement treatment as usual (TAU) to reduce the risk of suicide among these patients.

METHODS

We conducted a pragmatic randomized controlled trial on discharged patients aged between 18 and 45 years with self-harm episodes/suicide attempts, all of whom were recruited from 4 hospital emergency departments in Hong Kong. Participants were randomly assigned to one of three groups: (1) mobile app + TAU (“apps”), (2) mobile app + volunteer support + TAU (“volunteers”), or (3) TAU only as the control group (“TAU”). They were asked to submit a mobile app–based questionnaire during 4 measurement time points at monthly intervals.

RESULTS

A total of 40 participants were recruited. Blending volunteer care with a preprogrammed mobile app was found to be effective in improving service compliance. Drawing upon the interpersonal-psychological theory of suicide, our findings suggested that a reduction in perceived burdensomeness and thwarted belongingness through community-based caring contact are linked to improvement in hopelessness, albeit a transient one, and suicide risk.

CONCLUSIONS

A combination of volunteer care with a self-help mobile app as a strategy for strengthening the continuity of care can be cautiously implemented for discharged patients at risk of self-harm during the transition from the hospital to a community setting.

Authors: Mulyani Yani , Hasimun Patonah , Nurjanah Siti
Published: October 2022

Toxicity is a condition that indicates a harmful effect contained in a substance such as turmeric, which is an effective traditional medicinal plant used for antihypertensive treatment. Therefore, this study aims to determine the effect of repeated dosing of turmeric (Curcuma longa L.) rhizome extract. This subchronic toxicity study was divided into 4 groups, namely 1 normal treated with 0.5% Na-CMC, and 3 treatments with turmeric extract at doses of 50, 100, and 200 mg/kg BW for 28 days with each group consisting of 5 males and 5 female Wistar rats. The results showed that the turmeric extract at doses of 50, 100, and 200 mg/kg BW did not cause toxicity to liver and kidney biochemistry nor contain any toxic substances that might cause anemia or other abnormalities. Furthermore, histopathological examination showed that the tissues were normal. This indicates that the turmeric rhizome extract at all dose variations indicate non-toxic when used in traditional medicine.

The essential oil of lavender, lemon, and cinnamon (LaLC) combination is rich in antioxidants and potentially be used as an anti-wrinkle and strengthens the collagen tissue. Ultraviolet B (UVB) radiation is a free radical source that accelerates the aging process and reduces collagen production. This study aims to characterize the chemical components of each oil and determine the best combination as an anti-wrinkle substance. The test was conducted on twenty-four Wistar male rats (Mus musculus) that were divided into six experimental groups consisting of the normal (N), control (C), vehicle control (V), first treatment (T1), second treatment (T2), and third treatment (T3) groups. Each sample was rubbed upon, and the UVB irradiation was administered frequently to each subject. The embedded skin specimen was analyzed using a digital-capable microscope. Data were analyzed through the Kolmogorov-Smirnov normality test, one-way analysis of variance (ANOVA), and the post-hoc Tukey's Honest Significant Difference test. Lavender, lemon, and cinnamon essential oils contained each most significant component, which was linalool (41.46% peak area), dl limonene (44.74% peak area), and 2-propenal, 3-phenyl- (CAS) (53.89% peak area), respectively according to the Gas Chromatography-Mass Spectrometry (GC-MS) analysis. The T1 showed the best score of all parameters and did not show significant significance compared to the N group. In conclusion, the 1:1:3 combination of LaLC is better in preventing in vitro photoaging than other treatment groups.

A knowledge management strategy is urgently needed at this time, due to the high level of Industrial Disputes, the Department of Manpower has to improve its human resources. In this study, the knowledge-based organizational model is used as a solution to the application of knowledge management strategies to solve the problems faced by industrial dispute mediators today. Before implementing the knowledge-based organizational model, it is necessary to first measure the quality and quality of human resources in the Ministry of Manpower using a Likert scale and testing the quality of human resource management by combining the knowledge management approach. The Likert scale calculation and quality testing reached the same conclusion, namely the quality of human resource management at the Ministry of Manpower was good (Likert scale = 3.78 while the actual percentage = 75.88%). Although this has already been stated to be beneficial, it is necessary to increase the quality of the employees of the Department of Manpower to improve industrial disputes.

Published: October 2022

Abstract: The use of recycled waste materials in road pavements is currently seen as a viable solution not just in terms of environmental sustainability, but also in terms of improving service performance.[1] This is particularly true when it comes to recycled plastics. Thin plastic bags are primarily composed of low-density Polyethylene and it’s commonly used for packaging, protecting and many other applications. Nevertheless, disposal of waste plastic bags in large quantities constitutes an environmental problem, as they considered non-biodegradable materials. Hence, there is a real need to find useful applications for these growing quantities of wastes. In this research, Waste Plastic Bags (WPB) as one form of polymers are used to investigate the potential prospects to enhance asphalt mixture properties. Research aims include studying the effect of partial replacing of different percentages of WPB pieces of the bitumen as binder modifiers on the properties of asphalt mix comparing it with conventional mix properties, besides identifying the optimum percent of WPB to be added in the hot mix asphalt. WPB were presented in the asphalt mixture in pieces with size (2 x 5 mm2 ). Marshal mix design procedure was used, first to determine the Optimum Bitumen Content (OBC) and then further to test the modified mixture properties. In total, (39) samples were prepared, 15 samples were used to determine the OBC and the remaining were used to investigate the effects adding different WPB percentages to asphalt mix. The OBC was 5.6 % by weight of asphalt mix. Seven proportions of WPB by weight of OBC were tested (2, 4, 8, 12, 16, 20 and 24%), besides testing of ordinary asphalt mix. Tests include the determination of stability, bulk density, flow and air voids

Efficacy of Paracrine Factors from Mesenchymal Stem Cells for Treating Biofilm-Infected Wounds in a Murine Model
Authors: Smith Alison A. , Bellows Charles F.
Published: October 2022

Background: Chronic wounds are a serious medical condition affecting over 6 million people in the United States. Biofilms, which alter the host immune response and establish a microenvironment that prevents wound healing, are intimately associated with the development of chronic wounds. Current treatment options do not specifically target the underlying molecular mechanisms of biofilm pathology. Paracrine factors secreted by mesenchymal stem cells (MSCs) have been demonstrated to play an important role in wound healing. The objective of this study was to examine the effects of the paracrine factors secreted from MSCs on reducing infection and accelerating wound closure in biofilm-infected wounds.Methods: MSCs were cultured by seeding on an extracellular matrix (ECM). The supernatant from MSCs containing paracrine factors were applied to mature Pseudomonas aeruginosa biofilms in vitro and the number of viable bacteria were quantitated. BALB/cJ mice were wounded and infected with P. aeruginosa biofilms and the paracrine factors from reprogrammed MSCs were applied topically. The wound surface area and colony forming units counts of the treatment group were compared to control (culture media) and biofilm (untreated) groups. Results: The paracrine factors from MSCs grown on ECM were found to reduce P. aeruginosa biofilm growth significantly (P<0.01). Wounds in the treatment group had lower bacterial counts and an increased rate of wound closure compared to non-treated mice wounds. Conclusion: The results indicate that paracrine factors from reprogrammed MSCs accelerated wound healing and reduced the bacterial burden in biofilm-infected wounds. Future studies are needed to further characterize this phenomenon.
Early Compression Therapy for Deep Skin Defects: A New Treatment Option to Prevent Hypertrophic Scars or Contractures
Authors: Lee Key Day , Cho Jaeyoung , Kang Sang Yoon , Burm Jin Sik
Published: October 2022

Background: Conservative treatment of deep dermal or full-thickness skin defects often results in hypertrophic scars or contractures; thus, compressive therapy has been used after wound closure to prevent or treat scar deformities. However, wound contraction begins in the early proliferative phase and peaks after 2 weeks. We therefore attempted early compression therapy as a means of conservative treatment of deep-skin defects and evaluated its clinical outcomes. Methods: In 21 cases of deep skin defects (19 patients), early compressive therapy was started the second week after injury. Saline-moistened gauze or foam dressings were placed on open wounds, and foam dressings or silastic plates were used after epithelialization. The compression materials included elastic bandages, adhesive tapes, or garments. The final scars were assessed using the Vancouver Scar Scale (VSS) and satisfaction degree.Results: Defect size ranged from 1.4×0.7 to 5×5 cm. The duration of compression was 4 to 12 months. The follow-up periods were 4 to 61 months. Mild scar hypertrophy or contracture occurred in 15 cases and subsided after application of topical corticosteroid or triamcinolone injection. The final scar shapes were linear (n=12), geographic (n=5), and oval (n=4). The mean VSS score was 2.3. The degrees of satisfaction were excellent (61.9%) and good (23.8%). In most cases, aesthetically and functionally satisfactory outcomes without pathologic scars were demonstrated with minimal scar size, high scar quality, and high satisfaction.Conclusion: Early compression therapy might be a good option to prevent pathologic scars in the conservative treatment of deep skin defects.

Published: October 2022

Perai River has been recognized as an additional raw water resource for
Penang state. Inadequate waste management can lead to river pollution.
River water contamination with metals such as light and heavy metals and
metalloid is a global concern that negatively impacts human, plant and
aquatic life. Therefore, this paper aims to evaluate the potential
sources and impacts of toxic metals at downstream of the Perai River
basin. There were 15 sampling points located at possible pollution
sources and a sample at the river outfall. In the dry season, samples
were taken in two different tidal: low and high tide. According to
spatial distribution analysis, Al and Hg levels were observed to be
higher than the standard limits during low tide. Meanwhile, Al, As, Hg
and Se were significant during high tide. Significant contamination of
Al was noticeable upstream during low and even high tide. Pollution of
Al and Hg may have started beyond the research zone, as the
concentrations were highest upstream during low tide. As was high in
certain areas and Se started high at the outfall during high tide. The
concentrations gradually decreased to upstream. It concluded that Al,
Hg, and As pollution comes from anthropogenic and Se from seawater
intrusion. Al and As highest concentrations exceeded the chronic value
for aquatic life. Yet, Hg gave a threatening concentration value to
plants and aquatic life. Government authorities must take steps to
resolve this issue in order to protect the river ecosystem and prevent
human health problems.
Power sharing in islanded microgrid with adaptive droop controller
Authors: sabzevari kiomars
Published: October 2022

Microgrid, which can be considered as an integration of various
dispersed resources (DRS), is characterized by the number of DRs
interfaced through the power electronics converters. The microgrid
comprising these DRs is often operated in an islanded mode. The droop
control method is traditionally adopted to distribute active and
reactive power among the DRS operating in parallel. However, the
accuracy of distribution of reactive power among the DRS controlled by
the conventional droop control approach is highly dependent on the value
of line impedance, R/X i.e. resistance to reactance ratio of the line,
voltage setting of inverters etc. In this paper, a control strategy has
been presented to improve the reactive power sharing among distributed
generation units in the islanded microgrids. The proposed control method
is based on exerting reactive current injection to correct the output
reference voltage is the common method of droop control. Reactive power
distribution error is reduced by modifying the reference voltage. To
evaluate the performance and effectiveness of the proposed control
strategy, it is implemented on an island microgrid consisting of three
distributed generation units. The simulation results show the proper
performance and efficiency of the proposed method.
eBoF: Interactive Temporal Correlation Analysis for Ensemble Data Based on Bag-of-Features
Authors: Ding Zhifei , Qian Rongtao , Chen Siru , Yu Lingxin , Han Jiahao , Zhu Yu , Liu Richen
Published: October 2022

We propose eBoF, a novel time-varying ensemble data visualization
approach based on bag-of-features (BoF). In the eBoF model, we take a
simple and monotone interval from all target variables of ensemble
scalar data as a local feature patch of BoF model and the duration time
of each interval (i.e., feature patch) as its frequency. The feature
clusters in ensemble runs are then identified based on the similarity of
temporal correlations. eBoF generates the clusters together with their
probability distribution across all the feature patches while storing
the geo-spatial information, which is often lost in the traditional
topic modelling or clustering algorithms. The probability distribution
across different clusters can help to generate reasonable clustering
results evaluated by the domain knowledge. We conduct several case
studies and performance analyses. We also consult the domain experts to
evaluate the proposed eBoF model. Evaluation results suggest the
proposed eBoF can provide insightful and comprehensive evidence on
ensemble simulation data analysis.
Intelligent System to Detect Software Defects in Autonomous Cars
Authors: Tanwar Sudeep , Patel Smit N. , Patel Jil R. , Patel Nisarg P. , Gupta Rajesh , Zeadally Sherali
Published: October 2022

Autonomous cars have become increasingly popular in the last decade
because of their numerous benefits, such as lower travel time, increased
safety, and improved fuel economy. Many car manufacturing companies and
tech giants are working on this technology to make fully autonomous
automobiles or strengthen their existing driver-less cars. These cars
use very complex, advanced, and sophisticated hardware technologies.
However, the software is an equally important feature because it must
operate all functions seamlessly while working in sync with other
vehicle components. The software must analyze a large amount of data to
make quick real-time decisions, so any vulnerabilities or bugs can be a
severe problem to the vehicle and the passengers riding in it. Many
researchers have proposed various software defect prediction schemes for
different projects and applications, but most of them have focused on
specific software issues and excluded others. Thus, their methods cannot
be applied to the software of autonomous cars. In this paper, we propose
an improved Artificial Neural Network (ANN) model, called
Dropout-Artificial Neural Network (D-ANN), to solve this problem of
defect prediction in autonomous cars. This inclusive model can consider
all the parameters simultaneously for effective bugs prediction. The
proposed model can be used for the software of any autonomous cars, and
it is trained and evaluated using standard methods. The results obtained
show that the proposed model predicts software defects with higher
accuracy than other models.
VLSI Architecture for Depth Invariant Real-time Fixed/Random Valued Impulse Noise Removal Algorithm for Back-end of Ultrasonography Systems
Authors: Sanki Pradyut Kumar , Biswas Rakesh
Published: October 2022

Ultrasound images often get distorted by impulse noise during
data acquisition and processing in the Back-end of the system, which
overlay the finer details of the scanned body parts. Generally, a
portable low-cost USG system doesn’t have an impulse noise-cleaning
module which hinders detections of smaller details in the images. A
Depth Invariant Impulse Noise Removal (DIINoR) algorithm and its
hardware architecture for real-time impulse noise removal from the
corrupt USG image are proposed in this paper. In this decision-based
algorithm, the corrupt pixel is first detected depending on the
homogeneity of the processing window and is restored with the median of
the window or previous pixel value. Testing of the DIINoR algorithm on
different USG images establishes that the denoised images have superior
quantitative performance compared to those of existing schemes.
Implementation of this architecture in VIRTEX-7 FPGA gives a maximum
clock frequency of 357.96 MHz. Synthesis of this architecture using UMC
90nm technology gives 103 mW power consumption at a clock frequency of
100 MHz with a gate count of 63K (NAND2) including two memory buffers
which proves its suitability for the real-time fixed and random valued
impulse noise cleaning in the Back-end of the portable USG system.
Is Thailand's hepatitis C treatment program at risk from its plans to join an Asia-Pacific trade pact?
Authors: Tenni Brigitte , Lexchin Joel , Akaleephan Chutima , Kittitrakul Chalermsak , Gleeson Deborah
Published: October 2022

Thailand has expressed interest in joining the Comprehensive and
Progressive Agreement for Trans-Pacific Partnership (CPTPP), an
11-country plurilateral trade agreement whose original incarnation
included the United States of America (USA). When the USA withdrew from
this agreement, key intellectual property clauses relevant to
pharmaceuticals were suspended. These could be reinstated should the USA
decide to re-join. This study aimed to measure the impact of these
suspended clauses by costing Thailand’s 2020 hepatitis C treatment
program under four scenarios: 1) existing treatment regime, which does
not use the currently recommended treatment regime and does not source
the lowest price medicines, 2) treatment regime if Thailand joined the
CPTPP and suspended clauses were reinstated, 3) treatment regime if
Thailand utilised flexibilities in international law enabling access to
the cheapest direct acting antivirals on the global market and 4)
lowest-cost generic pan-genotypic regime on the global market. Joining
the CPTPP would increase the cost of Thailand’s hepatitis C treatment
program more than tenfold if suspended CPTPP clauses were reinstated and
TRIPS flexibilities not fully utilised. Within the existing budget, the
price and regime for scenario 4 would enable an additional 7,571 people
to access hepatitis C treatment and avoid the need for genotype testing.
Signing trade agreements such as the CPTPP that require stronger
intellectual property protections could compromise Thailand’s hepatitis
C program and other national treatment programs reliant on affordable
generic medicines and prevent it from relying on its own pharmaceutical
capabilities to manufacture medicines needed to sustain its treatment
programs.
Using surface environmental DNA to assess arthropod biodiversity within a forested ecosystem

Published: October 2022

Terrestrial arthropods are abundant and diverse with outsized ecological
and economic importance. Our ability to monitor this diversity is
hampered by the variety of sampling techniques and taxonomic expertise
required to catalog the species in an area. DNA metabarcoding approaches
show promise but have mainly been limited to trapping studies where DNA
is extracted from captured individuals. Here we illustrate the promise
of terrestrial plant surfaces as reservoirs of environmental DNA (eDNA)
that is rich in arthropod biodiversity information. We posit that
collection of surface eDNA will enable easier and more rapid arthropod
inventories. We collected 40 paired samples using two novel terrestrial
surface eDNA sampling techniques – ‘roller’ tree bark and ‘spray’
foliage sampling – in a New Jersey, USA pine barrens forest.
Metabarcoding using two primer sets (COI and 16S) revealed the presence
of 177 arthropod families (from 21 orders), representing 80% of the
family-level diversity expected in the area based on accumulation
curves. Spray samples revealed more families than roller (148 vs. 126),
while the two methods showed distinct, though overlapping, community
composition. The two primer sets revealed similar alpha diversity,
although they also captured different taxonomic subsets. A more limited
comparison of roller and spray sampling with traditional aquatic and
soil eDNA samples revealed a greater family diversity in surface
samples, especially compared with soil. Our study highlights the value
of eDNA metabarcoding surveys for achieving the elusive goal of rapid,
cost-effective arthropod inventories, and thus realizing a range of
ecological research and management goals.

Machine learning methods can be used as robust techniques to provide
invaluable information for analyzing biological samples in
pharmaceutical industries, such as predicting the concentration of viral
particles of interest in biological samples. Here, we utilized both
convolutional neural networks and random forests to predict the
concentration of the samples containing measles, mumps, rubella, and
varicella-zoster viruses (ProQuad®) based on Raman and absorption
spectroscopy. We prepared Raman and absorption spectra datasets with
known concentration values, then used the Raman and absorption signals
individually and together to train RFs and CNNs. We demonstrated that
both RFs and CNNs can make predictions with R2 values as high as 95%.
We proposed two different networks to jointly use the Raman and
absorption spectra, where our results demonstrated that concatenating
the Raman and absorption data increases the prediction accuracy compared
to using either Raman or absorption spectrum alone. Additionally, we
further verified the advantage of using joint Raman-absorption with
principal component analysis (PCA). Furthermore, our method can be
extended to characterize properties other than concentration, such as
the type of viral particles.
Understanding the Potential Value of Cardiovascular Brain Death Donors to Increase the Heart Donor Pool.
Authors: Brozzi Nicolas , Baran David , Napoli Federico
Published: October 2022

Multiple approaches in recent years have been implemented to address the
persistent shortage of heart donors, including a recent modification of
UNOS heart allocation system, expanding donor acceptance criteria, and
adoption of novel techniques to utilize hearts from donors with
circulatory death. The opioid epidemic has resulted in an exponential
increase in deaths in the United States in recent years, particularly
affecting younger adults. A recent analysis of UNOS database by Jenser
et al. reveals a relative underutilization of heart donors with
cardiovascular mechanism of brain death which provide similar long-term
survival as donors with other mechanisms of brain death, highlighting
the potential role of these donors to provide life saving cardiac
allografts and mitigate the persistent shortage of hearts for
transplantation.
V zascitu politiceskoj filosofii
Authors: Semenov Andrej

Do XIX veka politiceskaja filosofija byla vseob''emljuscej naukoj o celoveke i obscestve. No s pojavleniem i razvitiem drugih social'nyh nauk, vsego za sto let, politiceskaja filosofija dostigaet tocki zakrytija. Isajja Berlin i ego kollegi smogli prodemonstrirovat', cto predmet politiceskoj filosofii ostalsja neizmennym so vremen Drevnej Grecii. Inymi slovami, do teh por, poka v nasem obscestve ne dominiruet tol'ko odna cel', poka suscestvujut razlicnye interpretacii ?mpiriceskih sobytij, i avtory, sposobnye otkryvat' normativnye istiny, politiceskaja filosofija budet zanimat' svoe mesto sredi obsce?stvennyh nauk. Ee mesto nahoditsja mezdu pozitivnoj politiceskoj naukoj i filosofiej. V to vremja kak pervaja otvecaet na vopros ?cto est'??, filosofija iscet otvet na vopros ?cto (dolzno byt' sdelano)??, a politiceskaja filosofija soderzit vopros ?cto delat', kogda est' raznoglasija po povodu togo, cto delat'?. Takim obrazom, v samom svoem bytii ostaetsja normativnyj podhod, no on ne obsuzdaetsja v kakom-tovakuume. Celi i predmeta, konecno, nedostatocno, ctoby nazyvat' delo naukoj, no ono dolzno obladat' sistematiceskim i organizovannym znaniem predmeta v forme poddajuscihsja proverke ob''jasnenij ili principov, kakih-topravil povedenija ili metodov. Blagodarja teorii spravedlivosti Rolza, a takze politiceskim teoretikam ego veka, my polucili metody, kotorye proverjajut myslitel'nyj process teorii. Odnako ispol'zovanie odnogo i togo ze metoda ne prinosit s soboj ravnogo urovnja teoretizirovanija. V to vremja kak teorija spravedlivosti Rolza sozdaet novoe obscestvo, normy kotorogo protivorecat nasemu suscestvujuscemu obscestvu, teorija konsocial'noj demokratii Lejpharta ucastvuet v modernizacii suscestvujuscej sistemy, opirajas' na ?mpiriceskie dannye i deduktivnye vyvody. Drugimi slovami, teorija spravedlivosti javljaetsja versinoj teoreticeskoj oblasti, a s drugoj storony, teorija konsocial'noj demokratii pokazyvaet nam niznjuju granicu teoretizirovanija, neobhodimuju dlja teorii.

Highlights

Aim:

Pediatric femoral central venous catheter insertion is sometimes difficult due to small vein size. External iliac vein (EIV) compression may provide a tourniquet effect to the femoral vein (FV) and may facilitate catheterization. This study was conducted to determine the effect of EIV compression on FV size and femoral venous catheterization success rates.

Methods:

This study had 2 parts. The first part was a single-arm experimental study. The second part was a randomized controlled trial. Children weighing 2.5–15.0 kg were included. First part: All patients received the same intervention and measurements. FV anteroposterior and medial-lateral diameters were measured by ultrasound without EIV compression, after which EIV was compressed using the assistant’s finger, and FV diameters were measured. Second part: Patients were randomized into compression and control groups. The compression group received EIV compression during femoral venous catheterization. The control group did not receive the compression.

Results:

A total of 30 patients (15 in each group) participated. EIV compression significantly increased FV anteroposterior diameter (3.36 ± 1.01 mm with compression, 2.39 ± 0.76 mm without compression, mean difference = 0.97 mm, 95% CI = 0.73, 1.21, P < 0.001) and medial-lateral diameter (4.58 ± 1.40 mm with compression, 3.86 ± 1.32 mm without compression, mean difference = 0.72 mm, 95% CI = 0.43, 1.01, P < 0.001). Catheterization success rates were not different between groups.

Conclusions:

EIV compression increased FV size, but the effect on femoral venous catheterization success rates was inconclusive due to a small sample size.

Authors: Weber Mark D. , Shepard Lindsay , Loscalzo Steven , Fowler Jessica , Conlon Thomas
Published: October 2022

Highlights

Femoral central venous catheter (CVC) placement is a common procedure performed in the pediatric intensive care unit. Femoral CVCs have a relatively low intraprocedural complication rate compared with other access sites. We describe a case of guidewire-induced transient complete heart block during femoral CVC insertion. This complication is rare in the pediatric population. The incidence of its occurrence and guidance to prevent this complication are discussed.

Published: October 2022

Background and purpose: Inducible displacement CT compares 2 CTs acquired in series but with alternated rotation of the femur. This provides visual and quantitative clues as to the mechanical situation, i.e., loosening, of a total hip arthroplasty. We report the accuracy of this method as well as the experience of integrating it into a clinical workflow.Patients and methods: This was a retrospective single centre study of 72 cases of suspected aseptic loosening were the surgeon after reviewing a standard plain radiograph saw a need for more information. The displacement CT and plain radiograph were compared either to intraoperative findings or a 1–3 year follow up questionnaire for patients that did not have revision surgery. Patients reporting degradation in status since the time of the displacement CT were called for a follow up plain radiograph. Sensitivity and specificity were assessed, and user experience gathered.Results: Of 72 enrolled patients 15 were lost to follow up. Of the remaining 57, 17 were judged by in-traoperative findings or follow-up to have had loose implants. For plain radiography the sensitivity and specificity were 59% (95% CI 35–82) and 85% (74–96). For displacement CT the corresponding values were 77% (56–97), and 100% (100–100) respectively. The tool was adaptable to clinical routine.Conclusion: Displacement CT with alternated rotations of the femur is a viable option to improve the diagnostic process for identifying aseptic loosening in a total hip arthroplasty.

Published: October 2022

The automotive shop is a business engaged in the automotive sector that serves vehicle repairs and sales of various kinds of vehicle spare parts. A marketplace is a place for buying and selling or a market that uses internet media. The current marketplace is still very common, making it difficult to find a marketplace that focuses on the automotive sector and difficult to find information about available automotive shops around. The automotive shop marketplace system can help to carry out the process of buying and selling vehicle spare parts and assist in finding various spare parts and information about available automotive shops based on the user's location. This system was developed on a web-based basis using the PHP programming language with the Laravel framework and integrated with the Leaflet API, RajaOngkir API, and Midtrans Payment Gateway as additional features in creating a marketplace. The leaflet API displays a map containing the location of the automotive shop listed on the marketplace. RajaOngkir API provides information about shipping costs to the buyer's place from the seller's place. Midtrans Payment Gateway bridges the payment process carried out by both parties so that it can take place properly. The method used in this research is to use the System Development Life Cycle (SDLC) waterfall method. The results of the research conducted were tested using the black-box method.
