Concurrent pyoderma gangrenosum and Takayasu arteritis in an infant: diagnostic challenges and treatment considerations
Authors: Özomay Baykal Gülcan , Sözeri Betül
Published: March 2024

Background. Takayasu arteritis (TA) is an uncommon chronic inflammatory and autoimmune disease primarily affecting large vessels, particularly the aorta and its branches. Skin manifestations have been documented in association with TA. Pyoderma gangrenosum (PG) is a chronic neutrophilic dermatosis characterized by destructive, necrotizing, and painful ulcers, predominantly found on the lower extremities. The coexistence of PG and TA is extremely rare, with most reported cases involving adult patients. Interestingly, the association between PG and TA appears to be more common in Japan compared to North American and European populations. Childhood TA (c-TA) accompanied by PG is exceptionally rare, with only 10 cases reported in the literature thus far.
Case Report. We present the case of a 7-month-old patient initially diagnosed with PG. Despite aggressive immunosuppressive therapy, the patient’s high acute phase reactants remained elevated. Although the abdominal ultrasound was normal, advanced imaging was performed due to severe abdominal pain. Contrast-enhanced computerized tomography angiography of the aorta and its branches revealed extensive vascular involvement consistent with TA.
Conclusion. In this report, we highlight an infantile case of PG that was subsequently diagnosed as infantile TA. Recognizing the rare association between PG and TA is important. Thorough evaluation and prompt diagnosis of TA in infants with PG can guide further investigations and prevent vascular complications.

Published: March 2024

Mount Gupit is an area with gold mineralization potential which is part of the Menoreh Mountains, in the Magelang area. Mineralization potential mapping was carried out using geophysics, namely the Induced Polarization method. Induced Polarization Method measurements were carried out in 5 trajectories in a relatively west to east direction and with varying path lengths. The configuration used is a dipole-dipole configuration with a: 10 meters and n: 1-6. Interpretation is carried out on the results of the Resistivity and Chargeability data inversion. The inversion results show a resistivity range from 2 to 400 Ohm-m. Resistivity values are divided into three criteria, namely low with a value of less than 10 Ohm-m as clay rock, medium with a range of (10-75) Ohm-m as pyroclastic breccia and high with a value greater than 75 Ohm-m as intrusion or chunks of andesite. The inversion results show that the chargeability value varies from 2 to 80 ms. This value is divided into three criteria, namely low (<10 ms), medium (10 to 35) ms and high (>35 ms). Low chargeability values are interpreted as zones that are not mineralized so that there are no metal minerals. The mineralized zone is being interpreted from a moderate chargeability value. Meanwhile, a high chargeability value is interpreted as a zone that is strongly mineralized and contains significant metallic minerals. The existence of a mineralized zone stretches from track 2 to track 5 to the north, while the zone has disappeared or been exhausted in track 1 to the south of the research area.

Innovations in material technology are expected to reduce the use of commercial cement and replace it with other environmentally friendly materials with the same performance as normal concrete. Aim: This study aim to analyze the mechanical property of High-Volume Fly Ash Concrete (HVFAC) using F class fly ash with different mix percentages. Methodology and Results: The experiment was conducted in laboratory scale. Four variations of test specimens consisted of: 1 variation (F0), which is conventional concrete with 100% Portland cement as control specimen, and three variations of HVFC (F70, F80, and F90), which were made with fly ash content (%) 70, 80, and 90 of total cementitious. Fresh concrete testing to determine workability, while hard concrete testing is done by density and compressive strength tests at the age of 3, 7, and 28 days on specimens that have been treated with the water submerged curing method. Conclusion, significance, and impact of study: All HVFAC specimens fulfill the Self Compacting Concrete (SCC) category. The compressive strength test results at 28 days showed that the addition of fly ash percentage caused a decrease in compressive strength values in all HVFAC variants, but still exceeded the minimum requirements of high and medium quality concrete. All HVFAC variations meet the requirements of ASTM C618-23 based on the evaluation of Strength Activity Index (SAI) values at 7 and 28 days of age. The utilization of 90% fly ash as a cement substitute resulted in an environmentally friendly concrete product based on the concept of cleaner production.

Published: March 2024

Multimode spacecraft propulsion combines two or more propulsive modes into a single system using a single propellant. In this study, a multimode system combining a monopropellant chemical decomposition mode with an electric electrospray mode is considered for specific NASA-relevant lunar small satellite missions. This multimode concept is compared to all-chemical and all-electric approaches for four design reference missions (DRMs) in terms of feasibility, propellant mass consumed, and transfer time. Point solution trajectories are developed using NASA’s General Mission Analysis Tool for each propulsion system. This is the first study to consider this multimode concept for specific missions with high-fidelity force modeling. The results demonstrate the multimode approach can complete three of the four DRMs within the allotted propellant budget, while the all-chemical approach fails to complete two DRMs and the all-electric system fails to complete one DRM. Across the three feasible DRMs, the multimode approach completes the mission in 11–55% less time than the all-electric approach while consuming up to 33% less propellant than the all-chemical approach. The number of switching events and the minimum required mode switching time are quantified for the first time, with the latter having values between nearly instantaneous and 112.5 days, depending on the mission.

Authors: Elangovan Gayathri Priyadharshini , Periasamy Indra Kumar , R Saravana Kumar , Ezhumalai Ahila
Published: March 2024

One of the etiological factors for Gingival Enlargement is administration of certain drugs like calcium channel blockers, anticonvulsants, and immunosuppressant. The drug that is been commonly used for the management of portal hypertension is calcium channel blockers. Among the various drugs in calcium channel blockers, the occurrence of drug-induced gingival enlargement is high with the use of nifedipine drug whereas the occurrence of gingival enlargement due to the usage of amlodipine drug is a very rare phenomenon. Amlodipine is a third-generation drug belonging to dihydropyridine calcium channel blocker that has been used for its longer duration of action. Treatment for drug-induced gingival enlargement includes referral of patients to their physician for possible drug substitution or alteration in dosage of drug, periodontal therapy that includes oral prophylaxis followed by gingivectomy or gingivoplasty, and maintenance care. In this study, we report a case of gingival enlargement in a 44-year-old female patient taking amlodipine drug for a period of six months and nonsurgical and surgical management of amlodipine-induced gingival enlargement in the patient.

Authors: Kharche Mahesh Satish , Khandaitkar Sandeep
Published: March 2024

Objectives:

A painful dental condition known as a dry socket (also known as alveolar osteitis) can occasionally develop after the extraction of a tooth. A dry socket occurs when the blood clot at the site of the tooth extraction dislodges before it has healed. The idea of treating dry sockets with medication-related combined treatment is relatively new. Many drugs have the ability to treat dry sockets. The study aimed to assess the knowledge regarding the combined treatment of dry socket among interns.

Material and Methods:

This cross sectional study was carried out at a dental college to evaluate the knowledge and awareness of dental students regarding treatment of dry socket.

Results:

The statistical analysis showed significance in knowledge about the combined treatment of dry socket. The participants had basic knowledge regarding various aspects of dry socket except recent advances.. Female interns showed more knowledge than male counterparts however, due to the unequal number of male and female participants the difference is not statistically significant. Basic knowledge regarding dry socket management was satisfactory however, awareness regarding newer advances needs to be improved.

Conclusion:

It is strongly recommended that the students should update their knowledge using continuing education programmes, journal articles so that they can manage this clinical condition effectively.

Published: March 2024

Despite the superfi cial localization of most dermatophytosis, host-fungus relationship in these infections is complex and still poorly elucidated. Though many efforts have been accomplished to characterize secreted dermatophytic proteases at the molecular level, only punctual insights have been afforded into other aspects of the pathogenesis of dermatophytosis, such as fungal adhesion, regulation of gene expression during the infection process, and immunomodulation by fungal factors. However, new genetic tools were recently developed, allowing a more rapid and high-throughput functional investigation of dermatophyte genes and the identifi cation of new putative virulence factors. In addition, sophisticated in vitro infection models are now used and will open the way to a more comprehensive view of the interactions between these fungi and host epidermal cells, especially keratinocytes.

Introduction: Hepatitis C Virus (HCV) infection is a global public health problem. The epidemiology of this condition in Parakou is still poorly understood. The aim of this study was to investigate the epidemiological, diagnostic and therapeutic aspects of hepatitis C virus infection in the internal medicine department of the Departmental and Teaching Hospital of Borgou-Alibori (DTH-B/A), Parakou. Patients and Methods: This was a descriptive cross-sectional study with retrospective data collection. It concerned patients received in hepato-gastroenterology consultation from 1st January, 2017 to 30 June, 2021. Patients who had undergone a minimal pre-therapeutic workup, which included testing for hepatitis C virus antibodies (anti-HCV Ac) and quantification of viral RNA by PCR, were included. The data were collected from each patient’s medical record and transcribed on a pre-established collection form. Analysis was performed using Epi Info software version 7.2. Results: During the study period, 2786 patients were seen in hepato-gastroenterology consultations. Among them, 142 patients (5.1%) were HCV-positive. Of these seropositive patients, 73 (51.4%) met the inclusion criteria and were selected for the present study. The mean age was 45.5±14.7 years. Thirty-nine (53.4%) were male, for a sex ratio of 1.2. Forty-seven (64.4%) had progressive HCV infection with detectable RNA, including 3 (6.4%) at the stage of liver cirrhosis. Treatment was indicated in these 47 patients (64.4%) and was effective in 35 (74.5%). In all these patients, the HCV RNA test at the control PCR at least three months after the end of treatment was negative (undetectable RNA), representing a sustained virological response of 100%. Conclusion: At DTH-B/A, HCV infection most often affects young adult males. Viremic forms are in the majority. Treatment with direct-acting antivirals remains highly effective.
Microwave Radiation in the Environment and Its Impact on the State of Living Organisms

In the early 1990s [1], we proposed a new agent of the impact of geocosmos on a set of processes in the lower atmosphere and biosphere - the microwave radiation of the earth's ionosphere, emitted by all its atoms, molecules and their ions when high-energy (Rydberg) states are excited by photo- and secondary electrons mainly during solar flares and geomagnetic storms. This made it possible to solve the main problem of the physics of solar-terrestrial relations, since it opened a previously unknown channel for the constant influence of space weather factors on terrestrial processes and the state of the human body. In addition, we proposed to take into account the existence of such a factor when assessing the safety of manned space flights beyond the Earth's magnetosphere [2,10,12], including during the operation of the Moon. In our approach - supramolecular physics of supramolecular structures of molecules with high affinity for the proton (including water in a living organism), we took into account the pioneering works [14,15], in which the possibility of the formation of "polyatomic Rydberg molecules" in such cases was found. Their existence, including in the biological molecules, was discussed in [18]. Here we used the analogy with molecular protonics considered for the biomedium within the framework of supramolecular chemistry [16]. In our studies of the geocosmic contribution to terrestrial processes, we proposed for the first time to take into account the role of microwave emission from the ionosphere in studying the problem of global warming. Such an emission causes the generation of optically thin upper clouds from water-containing associates, which delays the escape of thermal radiation from the surface atmosphere [4]. This was confirmed when interpreting the data of meteorological observations at an altitude of 2100 meters at the Kislovodsk station of the Leningrad University in 2003 [3].

The JC polyomavirus (JCPyV) belongs to the family Polyomaviridae, genus Betapolyomavirus. These are small, non-enveloped, double-stranded DNA viruses. Approximately 60-80% of the population is carriers of JC polyomavirus. Various ways of spread are being studied. These viruses are associated with a large spectrum of neurological diseases, including progressive multifocal leukoencephalopathy, JC-associated meningitis and encephalitis, JCV granule cell neuronopathy and numerous central nervous system malignancies. In the majority of individuals, the virus remains latent in the kidney tissue. However, in certain subgroups, it leads to the development of severe and frequently disabling or fatal diseases. These subgroups are usually immunosuppressed, which causes the virus to undergo lytic rearrangement. Understanding these diseases and the mechanisms by which they occur is paramount for making accurate diagnoses. Studying these diseases is necessary to develop effective treatments and limit their harmful effects.

The total poultry population in Ethiopia is estimated to be 51.35 million. The Poultry sector is a fastest growing among the animal production activities offers an opportunity to feed the fastest growing human population and provide income resources for poor farmers. There are different diseases which can affect chicken. Among the bacterial diseases, Infectious Coryza (IC) is an acute and contagious respiratory disease of chickens caused by the bacteria, Avibacterium paragallinarum. IC is distributed worldwide and typically transmitted by direct contact, airborne droplets and contamination of drinking water. But Egg transmission does not occur. The initial step in the pathogenesis of infectious coryza is adherence to and colonization of the nasal mucosa. The diagnosis can be based on a history of rapid disease spread, clinical symptoms, and pathological changes caused by IC. Diagnostic methods for IC include direct isolation, the HI test for serovar A and Polymerase Chain Reaction (PCR). Diagnosis of Avibacterium paragallinarum have been proposed as alternatives to conventional serotyping by the Page scheme. The HI test, which is one of the most widely used serological test, is often utilized to detect changes in antibody titers in cases of field infection or vaccination, and is useful for evaluating the prevalence of IC in certain areas. Rapid and accurate detection of respiratory IC has become a challenge because of the involvement of more than one agent with similar clinical signs and lesions, which complicates diagnostic decisions, as well as treatment and control strategies.

The oral supplementation with some amino acids (such as arginine, glutamine and Hydroxy-Methylbutyrate - HMB), vitamins and zinc could contribute to accelerate the healing process in subjects with chronic wounds such as pressure sores. In this mini review we summarized the rational and the evidences available regarding the possible role of some nutrients supplementation in the management of chronic wounds. In particular we focused on clinical data available for arginine, HBM, glutamine, vitamins and Zn oral supplementation. Several studies suggested that these foods could promote the recovery of muscle mass and the reconstruction of damaged tissue (e.g in patients with pressure sores, ulcers, sarcopenia and burns). Food supplements containing all these components are commercially available. These products could be useful in the management of subjects with or at risk of Pressure Ulcers (PUs). In addition, these formulas can be us as integrations in the treatment of sarcopenic subjects, a condition that could be associated to PUs. The use of specific oral nutritional formula not only could allow a better healing of PUs, but also can reduce the costs of healthcare system. In these respects, controlled clinical trials are warranted to confirm the efficacy of this supplementation strategy.
A reduction of the separability problem to SPC states in the filter normal form
Authors: Cariello Daniel
Published: March 2024

It was recently suggested that a solution to the separability problem for states that remain positive under partial transpose composed with realignment (the so-called symmetric with positive coefficients states or simply SPC states) could shed light on entanglement in general. Here we show that such a solution would solve the problem completely.Given a state in $ \mathcal{M}_k\otimes\mathcal{M}_m$, we build a SPC state in $ \mathcal{M}_{k+m}\otimes\mathcal{M}_{k+m}$ with the same Schmidt number. It is known that this type of state can be put in the filter normal form retaining its type. A solution to the separability problem in $\mathcal{M}_k\otimes\mathcal{M}_m$ could be obtained by solving the same problem for SPC states in the filter normal form within $\mathcal{M}_{k+m}\otimes\mathcal{M}_{k+m}$. This SPC state can be built arbitrarily close to the orthogonal projection on the symmetric subspace of $ C^{k+m}\otimes C^{k+m}$. All the information required to understand entanglement in $ \mathcal{M}_s\otimes\mathcal{M}_t$ $(s+t\leq k+m)$ lies inside an arbitrarily small ball around that projection. We also show that the Schmidt number of any state $\gamma\in\mathcal{M}_n\otimes\mathcal{M}_n$ which commutes with the flip operator and lies inside a small ball around that projection cannot exceed $\lfloor\frac{n}{2}\rfloor$.
Guidelines to use the ICSM for developing quantum-classical systems

Published: March 2024

Quantum computing is the turning point that represents a revolution in software development that will make it possible to solve those problems unsolvable with classical computing. Just as in other milestones in the history of software development, such as the adoption of object-oriented systems, where new software development processes and new life cycles emerged, with the quantum computing revolution, a new life cycle for quantum and hybrid software systems is needed. Although there are some life cycle proposals for quantum software systems, most of them do not comprehensively address the specific needs of these systems. In this paper, a quantum life cycle proposal is presented adapted from the Incremental Commitment Spiral Model (ICSM) and an example of its use is presented. nd that projection cannot exceed $\lfloor\frac{n}{2}\rfloor$.

OPTIMIZING PROJECT TIMELINES: THE IMPACT OF E-PROCUREMENT IN ACCELERATING PUBLIC SECTOR PROJECTS IN NIGERIA
Authors: Oniyangi Hauwa Aliyu , Ibrahim Umar Abbas
Published: March 2024

Purpose: E-procurement is recognized globally as a tool for enhancing efficiency and transparency, with major intergovernmental bodies advocating its adoption. This study investigates the impact of electronic procurement (e-procurement) on project completion times in the Nigerian public sector. The research focuses on e-tendering, e-invoicing, and e-sourcing, hypothesizing their effects on project completion times.
 
Theoretical Framework: The study employs a conceptual framework highlighting the interplay between e-procurement practices and government policies. Theoretical frameworks, including Innovation Diffusion Theory and Technology Acceptance Theory guided the study.
 
Design/Methodology/Approach: The study adopted a descriptive survey research design to collect primary data from 361 procurement staff from four agencies in Abuja using a structured questionnaire. Data collected were analysed using descriptive statistics and multiple regression analysis.
 
Findings: The results indicate a positive relationship between e-procurement practices and project completion times, with e-invoicing having the most significant impact. However, the introduction of government e-procurement policies as a variable diminishes the individual effects of e-tendering, e-invoicing, and e-sourcing.
 
Research, Practical & Social Implications: The study established a positive relationship between electronic procurement practices and project completion times, with higher implementation levels resulting in shorter project durations. However, organizations should evaluate their impact, balance oversight and efficiency.
 
Originality/Value: By focusing specifically on the Nigerian public sector, testing clearly defined e-procurement elements, collecting robust primary data, and generating new context-specific evidence, this study makes an original, timely and valuable contribution to knowledge on the impact of e-procurement adoption.
