Published: June 2023

Background

One of the most significant pathogenic bacteria is Staphylococcus aureus, and both adults and children are susceptible to this bacterium from the front of the nose. In the United States, the Centers for Disease Control and Prevention estimate that 80,461 invasive methicillin-resistant S. aureus (MRSA) infections and 11 285 related deaths occurred in 2011. In the UK, around 190 people passed away from MRSA disease in 2021. Australia, Hong Kong, Singapore, Japan, and Greece also have MRSA infections, along with the whole world. MRSA caused less than 2% of bacterial diseases in the United States in 1974, while the percentage rate jumped to 64% in 2004 only 10 years to increase the infection rate by 300%.

Objective

This study aimed to detect medication susceptibility patterns, staphylococcal enterotoxins A to C, toxic shock syndrome toxin-1, and methicillin-resistant genes.

Materials and methods

Ninety-eight S. aureus strains were isolated from different infection sites from Salah Al-Din Teaching Hospital. There have only been a few studies conducted on the epidemiology and virulence genes of S. aureus in Salah Al-Din city, Iraq.

Results and conclusion

The rates of drug resistance among S. aureus strains to routinely used antibiotics were found to be extremely high. In this study, the expression of toxic shock syndrome toxin, sec B, and sec C genes in S. aureus strains was not detected, unlike in previous studies. While all the strains were sec A gene positive, another gene found in bacterial cells that enables them to be resistant to antibiotics like methicillin and other vancomycin drugs is mecA.

Authors: Chandanwale Shirish Sahebrao , Ingale Yaminy Pradeep , Patel Payal , Verma Anubhaw
Published: June 2023

Pulmonary lymphangioleiomyomatosis (LAM) is an extremely rare low–grade neoplasm. It occurs either sporadically or with tuberous sclerosis complex. Sporadic type usually affects women in reproductive age group. The patient usually gives a history of dyspnea of long duration. With characteristic clinical findings including high-resolution computed tomography findings, a diagnosis of pulmonary LAM can be suspected. Histopathology findings in some cases can be subtle. Cells of LAM consistently express smooth muscle markers such as smooth muscle actin and desmin on immunohistochemistry. Cells also express melanocytic marker such as HMB-45, Melan-A, and microphthalmia transcription factor. Due to the scarcity of reports on morphological features in pulmonary LAM, we are tempted to report morphological features of lungs in a 36-year-old female who successfully underwent bilateral lung and heart transplant at a tertiary care center.

Authors: Priya  , Dutta Monika , Kenwar Deepesh Benjamin
Published: June 2023

Background:

Kidney transplantation is the treatment of choice for most of the patients with end-stage renal disease. Transplantation brings many responsibilities related to medication adherence, immunosuppression, prevention of infection, regular follow-ups, etc. To meet the challenges faced by postkidney transplant patients, there is a need for deeper understanding of how people with kidney transplant learn to adapt to life posttransplant.

Aim:

The present study aims to explore the lived experiences of postkidney transplant patients.

Materials and Methods:

A phenomenological research design was adopted. By using purposive sampling technique, 18 postkidney transplant patients were enrolled. Data were collected through unstructured interviews and analyzed by using descriptive statistics for quantitative and Colaizzi’s method for qualitative data.

Results:

Based on participants’ responses, total 9 themes and 26 subthemes were extracted after data analysis. The main themes emerged were as follows: relief from dialysis-associated problems, perceived social neglect before and after transplant, burden of posttransplant regimen, impact on occupation, attitude toward donor, posttransplant lifestyle modifications, concerns about future quality of life, effect on family and children, and facilitating agents in transplant process.

Conclusion:

The present study concluded that the quality of life of participants after transplantation had improved in terms of relief from the dialysis-associated suffering. Worries about duration of graft function, future health, and cost were prevalent. There is a need to provide additional information, multidimensional support, and interventions following transplantation that target these concerns. This may support kidney recipients, better prepare for adaptation to life after transplant, and lead to improvements in the patient experience.
Breaking the Barrier: Successful Kidney Transplant in Two Patients from a SARS-CoV-2-Infected Deceased Donor in India: Case Report and Short Review
Authors: Prakash Sudeep , Datt Bhaskar , Kumar Bharath N. , Shukla Abhishek
Published: June 2023

There is the acute shortage of organs in India due to very low deceased organ donation rate. The COVID-19 pandemic had a huge impact on organ transplant programs, leading to slowing down of these programs worldwide. At present, with the SARS-CoV-2 infection becoming endemic and frequently presenting as asymptomatic or mild infection, deceased donors are likely to be incidentally positive for this infection. Most guidelines worldwide advocate rejecting the organs from such donors. Utilization of organs from these donors can improve the donor pool. Data suggest that carefully selected nonlung organs from such donors, with asymptomatic or mild SARS-CoV-2 infection, dying of other causes, are not associated with adverse outcomes. We present the cases of two end-stage kidney disease patients on hemodialysis, who were transplanted with kidneys from a deceased donor, infected with SARS-CoV-2 virus. Over 3 months of follow-up, the patients did not show any sign of COVID-19 infection or COVID-related kidney dysfunction and are now maintaining normal kidney function. This was the first incident of a successful kidney transplant from donor infected with SARS-CoV-2 virus, in India.

Published: June 2023

Background:

The role of family function in the context of the occurrence of depression among stroke survivors is yet to be accorded adequate attention. This study set out to assess the relationship between family function and poststroke depression among stroke survivors attending clinical outlets of the University of Port Harcourt Teaching Hospital.

Materials and Methods:

A hospital-based cross-sectional design comprising of 381 stroke patients aged ≥18 years, selected consecutively, was employed in the study. The Beck’s depression inventory-II (BDI-II) and family adaptability, partnership, growth, affection, and resolve (APGAR) questionnaire were used to assess depression and family function, respectively. A P < 0.05 was considered statistically significant.

Results:

A total of 381 stroke survivors were involved in the study with mean age of 60.54 ± 13.41 years. The proportion of stroke survivors with poststroke depression in this study was 36.75% (n = 140). There was a significant negative correlation between BDI and family APGAR scores (P < 0.05). Logistic regression analysis showed that family function was significantly related to poststroke depression irrespective of sex. Stroke survivors from dysfunctional families were about 1.6 times more likely to have poststroke depression in comparison to those from functional families (adjusted odds ratio = 1.58; 95% confidence interval: 1.01–2.51; P < 0.05).

Conclusion:

Poststroke depression is not uncommon. There is a significant relationship between family function and occurrence of poststroke depression irrespective of age and gender of the stroke survivor. Therefore, efforts geared toward the improvement of family function among stroke-survivors should be implemented.
Delayed immune-mediated hepatitis after three cycles of pembrolizumab for the treatment of sinonasal melanoma
Authors: Kang S , Lee HJ , Lee HJ
Published: June 2023

Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that induce the anti-tumor effects of T cells by targeting co-inhibitory immune checkpoints. The development of ICIs has revolutionized the clinical practice of oncology, leading to significant improvements in outcomes; therefore, ICIs are now standard care for various types of solid cancers. Immune-related adverse events, the unique toxicity profiles of ICIs, usually develop 4–12 weeks after initiation of ICI treatment; however, some cases can occur >3 months after cessation of ICI treatment. To date, there have been limited reports about delayed immune-mediated hepatitis (IMH) and histopathologic findings. Herein, we present a case of delayed IMH that occurred 3 months after the last dose of pembrolizumab, including histopathologic findings of the liver. This case suggests that ongoing surveillance for immune-related adverse events is required, even after cessation of ICI treatment.

Authors: Elatroush Hatem , Ragab Dalia , Mashhour Karim , Afify Mohamed , Salah Ahmed
Published: June 2023

Background

Early outcome prediction in ischemic stroke is a crucial concern for clinicians for proper decisions to reduce morbidity and mortality. The present study aimed to compare between computed tomography (CT) perfusion, National Institutes of Health Stroke Scale (NIHSS), and S100β for early outcome prediction.

Patients and methods

The study was carried out on 50 adult patients with acute ischemic stroke, classified into two groups according to modified Rankin score into group I (favorable outcome) and group II (unfavorable outcome). CT-perfusion was done on admission, NIHSS was calculated on admission, and blood was withdrawn on admission and third day for S100β.

Results

Infarction core size and the penumbra size were larger significantly in unfavorable-outcome group (P<0.001). Also, S100β levels and NIHSS on admission were higher in group 2 than group 1 significantly (P<0.001, P=0.001, respectively).

Area under the curves were 0.787 for NIHSS score, 0.877 for S100β level, and 0.844 for penumbra size. A combination between penumbra size, S100β, and NIHSS to predict outcome. The receiver operating characteristic curve yielded an area under the curve of 0.905 (P<0.001). Furthermore, the comparison between a combination of penumbra size, S100β, NIHSS on admission, and the final infarct in noncontrast CT on day 3 had a significant positive correlation coefficient (r=0.577, P<0.001).

Conclusion

We suggest that higher NIHSS score on admission, large core and penumbra size, and high S100β level are independent early predictors of the functional outcome for acute ischemic-stroke patients. Moreover, detecting cases with NIHSS score more than 19, S100β more than 241 pg/ml, core size more than 10.35 cm3, and penumbra size more than 17.9 cm3, can individually predict unfavorable functional outcome in acute ischemic-stroke patients. Hence, using these cutoffs in combination might predict the outcome in a more precise manner.

Published: June 2023

Thoracic surgery is one of the most common surgeries that causes severe postoperative pain. Inadequate pain management results in longer hospital stays and recovery periods, as well as psychological changes, quality of life, and patient satisfaction. Ultrasound-guided serratus anterior plane block (SAPB) is a promising interfascial plane block that may provide adequate analgesia. We report three cases of suspected lung cancer patients who underwent thoracoscopic biopsy and postoperative chest drainage. The patients underwent SAPB with light sedation during the procedure. After surgery, the patients were observed in the intensive care unit. For postoperative pain management, nonsteroidal anti-inflammatory drugs (NSAIDs) were used as an adjunct to intraoperative SAPB. Adequate pain control was achieved on a numeric rating scale of 0 to 2 over the 1 × 24 postoperative period, and opioid analgesics were not used in these patients. SAPB was successfully used in patients undergoing thoracoscopy biopsy surgery, with excellent outcomes in pain control after the surgery, reduction in perioperative opioid administration, and decreased postoperative pulmonary complications.

Published: June 2023

Aiming at the problems of model security and user data disclosure caused by the deep learning model in the Internet of Vehicles scenario, which can be stolen by malicious roadside units or base stations and other attackers through knowledge distillation and other techniques, this paper proposes a scheme to strengthen prevent against distillation. The scheme exploits the idea of model reinforcement such as model self-learning and attention mechanism to maximize the difference between the pre-trained model and the normal model without sacrificing performance. It also combines local differential privacy technology to reduce the effectiveness of model inversion attacks. Our experimental results on several datasets show that this method is effective for both standard and data-free knowledge distillation, and provides better model protection than passive defense.

Disentangling completed transactions in the UK: experiences and challenges
Authors: Knight Alex , Ricciardi Carolina , Alchini Matteo , Pantling Steven
Published: June 2023

The UK has a voluntary, non-suspensory merger control regime, such that mergers, acquisitions and other transactions can be, and routinely are, completed before they are investigated by the CMA. However, the CMA can, and often does, investigate mergers, acquisitions and other transactions that have not been notified to it. It has powers to prevent further integration between the merging parties’ businesses, and to require existing integration to be unwound, pending the conclusion of its investigation. Where the CMA identifies competition concerns, whether at Phase 1 or Phase 2, the fact that a merger, acquisition or other transaction has been completed can give rise to difficulties in identifying, implementing and ensuring the effectiveness of a remedy. This article discusses the CMA’s powers to impose interim measures and its approach to remedies in completed transactions. It also discusses the lessons that the CMA has learned from implementing remedies in merger investigations into completed transactions.

Authors: Zhong Xuefeng , Che Shuai , Xie Congying , Wu Lan , Zhang Xinyu , Tian Lin , Liu Chan , Li Hongbo , Du Guoying
Published: June 2023

Light quality is a common environmental factor which influences the metabolism of biochemical substances in algae and leads to the response of algal growth and development. Pyropia yezoensis is a kind of economic macroalgae that naturally grows in the intertidal zone where the light environment changes dramatically. In the present study, P. yezoensis thalli were treated under white light (control) and monochromatic lights with primary colors (blue, green, and red) for 14 days to explore their physiological response to light quality. During the first 3 days of treatment, P. yezoensis grew faster under blue light than other light qualities. In the next 11 days, it showed better adaptation to green light, with higher growth rate and photosynthetic capacity (reflected by a higher rETRmax = 61.58 and Ek = 237.78). A higher non-photochemical quenching was observed in the treatment of red light than others for 14 days. Furthermore, the response of P. yezoensis to light quality also results in the difference of photosynthetic pigment contents. The monochromatic light could reduce the synthesis of all pigments, but the reduction degree was different, which may relate to the spectral absorption characteristics of pigments. It was speculated that P. yezoensis adapted to a specific or changing light environments by regulating the synthesis of pigments to achieve the best use of light energy in photosynthesis and premium growth and metabolism.

Authors: Luong Xuyen Thi Hong , Liang Chenju
Published: June 2023

Atrazine (ATZ) is one of the most widely used herbicides for the control of annual broadleaf and grassy weeds in the world. Its residual in the environment is of great concern. This research work primarily focused on examining ATZ degradation by the ferrous ion activated persulfate (PS) oxidation process (Fe2+-AP process) and the influence of oxidative parameters on the degradation of ATZ in aqueous phase. The Taguchi Design of Experiment methodology was used to explore the effects of various operational parameters, including ATZ concentration, dosage of Fe2+, dosage of PS, and pH condition (Taguchi L9 orthogonal array). The optimal operational conditions were then determined based on the results of ANOVA statistical analysis. Operational conditions included ATZ at an initial concentration of 5 mg/L, with initial concentrations of 1 mM Fe2+, 10 mM PS, and pH = 3, at 20oC, for a reaction time period of 3 h. The sensitivity of factors for the ATZ degradation followed the decreasing order: PS concentration, pH, ATZ concentration and Fe2+ dosage. The results of this study provide useful operational conditions for the Fe2+-AP process, for application to field remediation of ATZ contamination.
Phenol degradation on electrochemically self-doped TiO2 nanotubes via indirect oxidation
Authors: Kim Seonghwan , Kim Choonsoo
Published: June 2023

Recently, electrochemically self-doped TiO2 nanotubes (R-TiO2 NTs) have emerged as promising anodes in the electrochemical oxidation process for wastewater treatment, owing to their high degradation capability of organic compounds. However, the degradation mechanism of organic compounds on R-TiO2 NTs has not been well demonstrated, and therefore, industrial practices have been limited. This study aimed to elucidate the oxidation mechanism of organic compounds on R-TiO2 NTs by investigating phenol degradation. The performance of phenol degradation on R-TiO2 NTs was comparable to that on the boron-doped diamond (BDD) electrode that is well-known as an excellent anode for phenol degradation. In particular, phenol degradation on R-TiO2 NTs was completely achieved at the electrode potential of 5.0 V while negligible degradation was found at the electrode potential of 2.0 V. In addition, no peaks associated with phenol oxidation in cyclic voltammograms were noticed on R-TiO2 NTs at the potential range between 1.0–2.5 V. Considering direct oxidation is a fundamental factor for phenol degradation at low electrode potential, it contributes less to phenol degradation on R-TiO2 NTs. Therefore, phenol degradation on R-TiO2 NTs is mostly owing to indirect oxidation mediated by hydroxyl radicals.

Authors:   Korea Institute of Design Research Society, Chung Donghun
Published: June 2023

This study measured the effect of visual and tactile elements in Virtual Reality (VR) games on game user experience. We conducted an experiment with 44 participants in a VR shooter game. We manipulated the visual complexity, perspective, and controller weight of the game environment. We found that the rate of first-person perspective usage was higher when the visual complexity of the shooter game was high. We also found that there were significant differences in presence and flow according to visual complexity, with higher presence when the visual complexity was low and higher flow when the visual complexity was high. Weight, a tactile factor, did not have a significant effect on user experience. These findings suggest that in future VR game development, developers should consider the amount of information in the game and use a third-person perspective along with a first-person perspective for effective development.
Road Traffic Noise Predictions by means of L10 Modelling with a Multilinear Regression Calibrated on Simulated Data
Authors: Rossi Domenico , Mascolo Aurora , Guarnaccia Claudio
Published: June 2023

Estimation of road traffic noise is fundamental for the health of people living in urban areas, and it is usually assessed based on field-measured data. Real data may not always be available, anyway, and for this reason, predictive models play an important role in the evaluation and controlling of the noise impact. In this contribution, the authors present a multilinear regressive model calibrated on simulated noise levels instead that on real measured ones, correlating percentile noise levels to independent traffic variables. The model efficiency is then evaluated on two field measurement datasets by analyzing data statistics and error metrics. Results show that the model provides good results in terms of mean error (less than 1 dBA on average) even if slight underestimations and overestimations are present. The presented model, then, can be used to assess the impact of road traffic noise anytime field measurements are not available, or even predict it when designing new road infrastructures.

Published: June 2023

Marine molluscs are economically very important and they are exploited by men for various purposes since the prehistoric times. Manufacture of ornaments is an age-old industry in the south and south-east India and molluscs as an ornament or souvenir are still in high demand. Although there is plenty of literature on the trade and economy of ornamental shells, exploitation of ornamental molluscs is less studied and limited to regions in the south and south-east India. The ornamental molluscs is widely traded in pilgrims places like Dwarka, Somnath and all along the coast of Gujarat, and with the exception of Turbinella pyrum (the chank shell), there is no literature available on ornamental mollusc taxonomy, utilization and trade in Gujarat. This is the first study on ornamental molluscs from Gujarat. We have reviewed the available literature on ornamental molluscs of India and established a comprehensive checklist as there is no checklist available for ornamental molluscs of India. A total 136 species were recorded as ornamental molluscs in India. Of these shells, 118 species were listed by reviewing the literature and 33 ornamental molluscs were added from on-site observations in which 18 species were recorded for the first time from the study area. A total of 11 species among the 136 species were protected under wildlife protection act 1972. Different use of ornamental species was studied and classified accordingly. With respect to families, the majority of contributions were from Cypraeidae (7 species) followed by Muricidae (3 species), Turbinellidae (2 species), Strombidae (2 species) and Cardiidae (2 species). The major source of ornamental imports was from south India with some souvenirs collected from nearby intertidal areas and sold by local vendors as whole shells. Due to the extensive trade of ornamental shells, there is a need to study the degree of exploitation of ornamental molluscs in India, particularly in Gujarat.

The semantics of the concept of “digital twin of a railway station” is investigated for compliance with the existing technical and informational level of obtaining an adequate digital image of a complex dynamic system that can correctly reproduce the dynamics of technological processes and states of infrastructure objects and rolling stock under certain conditions initial conditions and factorial influences. The digital twin of the station is a visualized model image of a complex technical system, in which the model rules constructing the technology make it possible to acquire models with additional degrees of freedom, leading to the possibility of reconstructing multidimensional variations of the potential states of cars and railway track.

It is proposed to use an alternative concept of an information replica, as reflecting the adequacy of the form and content of three-dimensional dynamic models of various objects of railway stations.

The possibility of developing a model info-replica to the level of a digital twin of the station is being studied in the formation of a software environment for modeling the physics of processes and reliable forecasting of the states of objects in the foreseeable event horizon with the production of dangerous states of infrastructure and rolling stock and a program-controlled return to the zone well, the regulatory technology of the station.

The results obtained will make it possible to form a definite and stable point of view on the functional field of the possible use of the term “digital twin of a railway station”.

Ukhuwah Islamiyah bisa terwujud ketika hati seorang muslim itu bersih dari sifat- sifat yang buruk dan tercela. Menurut al-Qur‟an setiap manusia diberi dua potensi sejak lahir, yaitu potensi fujur (buruk) dan potensi taqwa (baik). Hendaknya potensi fujur jangan dibiarkan tumbuh dan berkembang. Dan seharusnya memupuk potensi taqwa dengan cara mensucikan hati dengan cara mengikuti ibadah mahdah dengan tertib setiap hari dan menjaga kepekaaan sosial terhadap sesama muslim dengan merealisasikan ta‟aruf, tafahum, ta‟awun serta takaful. Jika hati sudah bersih maka menjalankan Ukhuwah Islamiyah itu akan menjadi mudah.
