Authors: Zachariae H , Heickendorff L , Bjerring P , Halkier-Sørensen L , Søndergaard K
Published: July 2023

Forty-four patients with systemic sclerosis and 3 patients with localized scleroderma were investigated for plasma endothelin and aminoterminal propeptide of type III procollagen (PIIINP). Although there was an overlap between plasma levels of endothelin in patients with systemic sclerosis and healthy controls, the mean value of the patients was significantly higher than in controls. Plasma endothelin was normal in all 3 patients with localized scleroderma. The highest levels of plasma endothelin were found in patients with type II and III systemic sclerosis with the largest cutaneous involvement, and in patients with the scleroderma-specific antibodies Scl-70 and anticentromere antibodies. Extremely high values were found in a patient who experienced a renal crisis and in a patient who had her lower leg amputated due to severe vasculitis. A positive correlation was found between plasma endothelin and serum PIIINP. This, together with the fact that in systemic sclerosis the vascular lesions are the earliest, would seem to support the theory that endothelial cell damage could lead to increased secretion of endothelin and subsequent fibrosis in this disease.

Authors: Veien N K , Hattel T , Laurberg G
Published: July 2023

Over a 2-year period, we saw 37 patients with a diagnosis of dermatophytid on the hands based on 1) culture-proven dermatophytosis on one or both feet 2) symmetrical, secondary vesicular eruptions on the fingers and/or palmar aspects of the hands and 3) a resolution in both areas of involvement after treatment of the dermatophytosis on the foot. During the study period, 128 patients had culture-proven dermatophytosis of the feet caused by Trichophyton rubrum. Nine of these (7%) developed dermatophytid. Seventy-eight patients had dermatophytosis of the feet caused by Trichophyton mentagrophytes. Twenty-seven of these (35%) developed dermatophytid. One of 6 patients infected on the feet with Epidermophyton floccosum developed dermatophytid.

Authors: Christensen O B , Anehus S
Published: July 2023

In total, 256 patients with bacteriologically verified impetigo contagiosa were included in three double-blind, parallel group, randomized, multi-centre trials, where the efficacy of hydrogen peroxide cream (Microcid) was compared with that of fusidic acid cream/gel (Fucidin). The trials were performed at 47 centres in three countries, Sweden, Germany and UK, and the results are compiled in the present report. During the course of the 3-week treatment period, 92 patients out of 128 (72%) in the Microcid group were classified as healed, compared to 105 patients out of 128 (82%) in the Fucidin group. This difference was not statistically significant. The reduction in composite sign severity score (the sum of the score for erythema, vesiculation/bullae, weeping and crusting divided by four) in each separate study was 73%, 78% and 84% in the Microcid group and 85%, 85% and 84% in the Fucidin group. No statistically significant differences were found in the separate studies or when compiling the studies in a meta-analysis. When the patients had been classified as healed, beta-haemolytic streptococci were eliminated in all patients treated with Microcid cream. Since treatment started before the result of the bacteriology was known, another 135 patients with negative skin culture were enrolled in the trials, i.e. 391 patients were included in the safety analysis. Out of these, 23 patients reported the occurrence of adverse events, mainly classified as mild. In conclusion, Microcid cream has been documented as a topical alternative to fusidic acid in the treatment of impetigo.

Published: July 2023

As several studies have demonstrated a relationship between decreased serum selenium concentrations and the frequency of certain cancers, we studied these concentrations in two kinds of cutaneous tumour cancer: melanoma and epidermotropic cutaneous lymphoma. We first determined the predictive value of the selenium assay for the frequency of recurrences in stage I and II melanomas and then considered the relationship between serum selenium concentrations before treatment and therapeutic response. Two hundred melanomas (81 stage I, 63 stage II, 56 stage III) and 51 epidermotropic cutaneous T-cell lymphomas (CTCL) (8 stage I, 24 stage II, 10 stage III, 9 stage IV) were included in the study. Selenium assays were performed by atomic absorption spectrophotometry (92 +/- 16 micrograms/l in 30 normal subjects). Our study showed decreased serum selenium concentrations for melanoma (81 +/- 27 micrograms/l) and lymphoma (78 +/- 36 micrograms/l) relative to disease severity. The concentration was significantly lower (76 +/- 22) for stage I and II melanomas with recurrence within 2 years (31 patients), compared to those without recurrence (113 patients) (p < 0.05). Before treatment, it was higher in CTCL with good response to treatment (89 +/- 36) than in those without response (62 +/- 30) (p < 0.01). This study thus demonstrates the prognostic value of selenium assays in the follow-up of melanoma and CTCL.

Published: July 2023

The aim of the present work is to shed light on the determining factors in the logistics performance of companies operating in the pharmaceutical sector in the Souss-Massa region. In order to maintain harmony between the object of our research and the methodological path taken to apprehend it, we have developed a conceptual model made up of thirteen variables spread over four levels stemming from the company's governance mechanisms, its logistics practices, its logistics tools and the company's structural contingency. Starting from a post-positivist paradigm that we have embedded in a hypothetico-deductive reasoning, the transition from the theoretical base to the empirical side of the study will be made through an investigation by third-order structural modeling with latent variables estimated according to the repeated indicators approach following a type II model (reflective-formative). In future work, this model will be tested on a designed sample of pharmaceutical industry partners (laboratories, dispatchers, pharmacies, etc.).

STUDI KOMPARATIF EKSISTENSI MANUSIA DALAM PANDANGAN J.P SARTRE DAN S.H NASHR
Authors: Mukhammad Lutfi
Published: July 2023

Penelitian ini mengkaji eksistensi manusia dalam pandangan J.P Sartre dan S.H Nashr. Penelitian inimenggunakan pendekatan hermeneutika dan metode yang digunakan dalam penelitian ini adalah deskriptif analisis. Metode deskriptif analisis digunakan untuk memaparkan bagaimana eksistensi manusia pandangan Barat dan Islam yang dalam hal ini difokuskan pada pemikiran Sartre dan Nashr. Jenis penelitian ini adalah library research. Hasilnya ditemukan ada titik temu sekaligus titik pisah dalam pemikiran keduanya. Titik pisah yang sangat mencolok terutama terilihat bagaimana keduanya melihat faktor lain di luar diri manusia, bisa jadi itu makhluk lain, manusia lain atau bahkan Tuhan. Dilihat dari sisi manusia sebagai objek Sartre berpendapat bahwa manusia yang tidak memiliki kesadaran akan nasibnya maka manusia itu tergolong ’etre-en-soi, sementara Nashr melihatnya sebagai fitrah bagi manusia, karena Tuhan telah menentukan nasib manusia sebelumnya. Dari sisi subjek, Nashr berpendapat manusia memang memiliki kekuasaan atas dirinya (khalīfah) sebagai subjek namun realitas itu merupakan amanat yang diberikan Tuhan kepada manusia, sementara Sartre mengartikan kekuasaan atau kebebasan itu sebagai sesuatu yang mutlak (’etre-pour-soi). Meski faktisitas menjerat, dan menghantui manusia Sartre menganggapnya sebagai materi kosong belaka. Nashr mengatakan manusia aktif sebagai khalīfah dan pasif menjadi hamba. Berkenaan dengan fungsi khalīfah, manusia harus mengaktifkan potensinya sebagai manusia universal dan manusia yang utuh.

Published: July 2023

Rural women play a significant role in agriculture and related industries in our nation and are essential to the welfare of farm households. The farm women perform a huge variety of tasks every day, including farming, raising and producing livestock, gathering forest produce, etc. In addition to their typical domestic duties, they also fetch water, fodder, and firewood for the family's needs as well as for the cattle. Women make up almost half of India's human resource pool. Many of them reside in rural areas, and many of them are uneducated, destitute, and under the poverty line. In addition, rural women have less access to a variety of resources than urban women. Therefore, it is necessary to alter their ability to work, broaden their knowledge, hone their talents, and raise their economic standing.
ChatGPT’s Capabilities in Spotting and Analyzing Writing Errors Experienced by EFL Learners
Authors: Algaraady Jeehaan , Mahyoob Mohammad
Published: July 2023

The recent Large Language Models (LLMs) use advanced algorithms to identify areas where sentence structure and word choice can be improved and to detect grammar, syntax, and spelling mistakes in sentences. This study aimed to investigate the effectiveness of the Chat Generative Pre-trained Transformer (ChatGPT) in detecting English as a foreign language (EFL) learners’ writing errors compared to human instructors. This study examines the ChatGPT as a recent and advanced LLM in analyzing and processing EFL learners’ writing issues. This paper provides valuable insights into the potential benefits and challenges of integrating Artificial Intelligence (AI) into EFL writing education. Our results revealed that ChatGPT successfully identified most surface-level errors but could not detect writing errors related to deep structure and pragmatics. Conversely, human teachers could spot most of these issues. These findings suggest that while ChatGPT can be a valuable tool in identifying surface-level errors, it cannot replace human instructors’ expertise and nuanced understanding in detecting errors related to the more complex aspects of writing. The writing error types (data) are statistically analyzed. The descriptive analysis displays valuable insights into the reliability of the data and its potential implications, where the F-score, which measures the statistical model accuracy, is found to be 1.5. In the meantime, the p-value score, which shows the probability of obtaining results as extreme as the detected data, is calculated to be 0.23. The results suggest that the collected data is statistically significant, and further analysis may yield valuable insights.

CV XYZ is a company engaged in the field of Bottled Drinking Water. The production process at this company still uses the traditional MMH (Manual Material Handling) method which causes various complaints from employees, so it is necessary to think of an alternative method or tool that can change this manual process. Based on this, this research was conducted to design a tool that can optimize the material handling process and reduce musculoskeletal risks that arise in employees. There are 3 methods used, namely anthropometry, the Nordic Body Map (NBM) questionnaire, and work posture analysis using the REBA method. After testing, it was found that the trolley table that was in accordance with the employee's anthropometry was able to reduce employee complaints by 25% on several parts of the worker's body. From the results of the REBA assessment, a score of 6 (moderate) is obtained if using a table trolley, while without a trolley it produces a score of 12 (has a very high risk). The results of this research are considered to have a significant impact both in optimizing the production system, as well as in terms of employee safety and health from an employee health and safety perspective.

This work reports the biological synthesis of zinc oxide nanoparticles and its calcium nanocomposites to study the photocatalytic deterioration of two dyes, viz. Rhodamine B and Methylene blue, under natural sunlight. Nanoparticles were synthesized using zinc acetate and starch extracted from potato at pH 7–8. Potato starch acts as both a capping agent and a reducing agent. They were characterized spectroscopically via XRD, SEM, HR-TEM, EDAX and FT-IR techniques. Bean/spherical shaped ZnO NPs were obtained in the size range of 29–49 nm whereas calcium coating on ZnO decreased the particle size, i.e., 25–35 nm. Their photocatalytic ability to degrade Rhodamine B and Methylene blue was studied under natural sunlight and monitored using UV-Vis spectrophotometer. Synthesized ZnO nanoparticles and its calcium coated ZnO nanocomposites showed promising results in degradation of these dyes. Methylene blue was completely degraded in an hour at 8 mg of the sample. Although degradation of Rhodamine dye was slow, synthesized samples were effective catalysts as compared to the ones reported in the literature.

Published: July 2023

OBJECTIVE

To describe the diagnostic findings, surgical techniques, and outcomes of thoracolumbar vertebral instability associated with or without articular process (AP) anomalies in Pekingese dogs.

ANIMALS

11 client-owned Pekingese dogs.

PROCEDURES

Medical records (2007 to 2022) were reviewed. Inclusion criteria were Pekingese dogs with thoracolumbar vertebral instability that underwent decompressive laminectomy and vertebral stabilization. Dynamic myelographic study and/or intraoperative spinal manipulation were used to diagnose vertebral instability. Data on preoperative and postoperative neurologic status, diagnostic findings, surgical techniques, and outcomes were retrieved.

RESULTS

The dogs presented with paraparesis (n = 9) or paraplegia (2). Five dogs had caudal AP anomalies. Dynamic myelographic study demonstrated single (n = 7) or multiple (4) dynamic compressions with poststress spinal cord height reduction (median, 12.5%; IQR, 6.8% to 21.2%). Of the 17 dynamic compression lesions, 5 lesions were at the disc spaces with caudal AP abnormalities. All dogs had vertebral instability confirmed by intraoperative spinal manipulation and underwent hemilaminectomy and unilateral vertebral stabilization. One dog had adjacent segment vertebral instability and underwent vertebral stabilization 3 months after the initial operation. All but 1 dog showed successful outcomes at the last follow-up (median, 16 months; IQR, 3 to 32 months).

CLINICAL RELEVANCE

Vertebral instability associated with or without AP abnormalities is a potential cause of thoracolumbar spinal cord injury in Pekingese dogs. Dynamic myelographic studies and/or intraoperative spinal manipulation demonstrated vertebral instability. Spinal cord decompression and vertebral stabilization are effective, resulting in neurologic improvements in most dogs.
Subconjunctival enucleation with or without third eyelid removal may present a viable enucleation technique in rabbits: 18 cases (2014–2022)
Authors: Hiebert Kara , Mans Christoph , Eaton Seth
Published: July 2023

OBJECTIVE

To evaluate intraoperative and postoperative complications and outcomes following subconjunctival enucleations with and without third eyelid removal in domestic rabbits.

ANIMALS

18 client-owned rabbits with ocular disease confined to the globe that underwent 20 subconjunctival enucleation procedures at a veterinary teaching hospital.

METHODS

Records were retrospectively reviewed for all enucleations performed at a veterinary teaching hospital from 2014 to 2022. A standard subconjunctival enucleation procedure was performed in all cases, with third eyelid removal in 2 surgeries and without third eyelid removal in the remaining 18 surgeries. Outcomes were assessed on the basis of observations in medical records and owner follow-up.

RESULTS

20 total enucleations were included. Reported reasons for enucleation included suspected or confirmed ocular Encephalitozoon cuniculi infection in 9 rabbits, refractory glaucoma in 4 rabbits, and various intraocular diseases in 5 rabbits. The only intraoperative complication reported was hemorrhage during the third eyelid removal in 1 surgery. Postoperative complications included serous to mucoid discharge from the surgical site in 8 of 20 surgeries and swelling at the surgery site in 2 of the 8 cases that had discharge. Postoperative swelling spontaneously resolved within 3 months of surgery; postoperative discharge spontaneously resolved within 10 months of surgery.

CLINICAL RELEVANCE

Subconjunctival enucleation with or without third eyelid removal in rabbits may be a viable enucleation technique to reduce the risk for intraoperative hemorrhage, but it can result in postoperative complications, including transient discharge and swelling at the surgical site.

In this study, we calculated the enthalpy (ΔH, kcal/mol), entropy (∆S, cal/K·mol) and free energy (ΔG, kcal/mol) thermodynamic values of each molecule for forty-seven different solvent media according to semi-empirical quantum methods (PM7, PM6, PM6-DH2, RM1, PM3, AM1, and MNDO) using the MOPAC computer program. The theoretical pKa values were calculated by placing these values in the thermodynamic cycle. It was determined that the triazole derivative molecules examined in this study showed a very high acidity in trifluoroacetic acid and a very low acidity in cyclohexane. The fifth molecule of the triazole derivative molecules examined in this study showed a very high acidity (pKa :1.2457) in trifluoroacetic acid according to the RM1 semi-empirical quantum method. On the other hand, it was determined that the fourth molecule showed a very low acidity (pKa : 69.5668) in cyclohexane according to the RM1 semi-empirical quantum method.
The Influence of Engagement in Value Co-Creation on E-Learning Experience and Student Satisfaction: An Empirical Study
Authors: Dziewanowska Katarzyna , Kacprzak Agnieszka
Published: July 2023

The objective of this paper is to investigate the impact of students’ engagement in value co-creation on the perception of online learning experience and the effect of online learning experience on student satisfaction. The research method was a survey conducted on a sample of 532 respondents from a public business school. The findings show that increased students’ engagement in value co-creation results in their improved perception of e-learning experience, which in turn influences student satisfaction. Thus, in order to facilitate the engagement of students in the value co-creation process, it is imperative to optimise the quality of dialogue, enhance the availability of pertinent information, promote intellectual stimulation, increase participation in scholarly pursuits, and foster opportunities for inter-student interactions. The study also complements the current body of knowledge on value co-creation in higher education with an online context.

Published: July 2023

The European Spallation Source (ESS) is a collaboration of 13 European countries to build the world’s most powerful neutron source for research. The project, situated in the south of Sweden, is approaching the end of the construction phase, and the first scientific results are planned for 2023. This paper gives an overview of mechanical design of the gamma blockers (GBs) in the accelerator to target (A2T) and dump line (DmpL) sections. The presence of GBs in the beam line should limit the gamma radiation emitted from the activated tungsten target and beam dump to allow the safe access of the staff to the machine. The presented design allows for efficient operation and the same shutting time independently of the vacuum status.

Introduction

Constrictive pericarditis can be a systemic manifestation of immune-mediated diseases. A timely diagnosis followed by ethiologic workup is essential for improving patient prognosis.

Case presentation

A 67-year-old female patient who suffered multiple episodes of anasarca in the past two years was referred to our center for heart failure with preserved ejection fraction. She was previously investigated for autoimmune diseases based on persistent inflammatory syndrome and recurrent serositis. The physical exam showed systemic congestion, hepatomegaly, and jaundice. Sinus tachycardia and low voltage were observed on the ECG. Transthoracic echocardiography showed septal bounce, “annulus reversus” and “paradoxus”, thickened pericardium without effusion, and a dilated inferior vena cava. Cardiac catheterization was performed, revealing equalization of diastolic pressures and square root sign, confirming constriction. A partial pericardiectomy was performed. The histopathologic study showed polyclonal plasma cells with frequent IgG plasma cells and a IgG4/IgG ratio of 40%, considered a mark of the IgG4 disease as causal.

Conclusion

Multimodality imaging completed the clinical suspicion of constrictive pericarditis. Complex pathologic analysis of the pericardium led to considering a diagnosis of IgG4 disease, and the patient was referred to a tertiary center for diagnosis and adequate therapeutic management. Constrictive pericarditis can be an associated manifestation of IgG4-related diseases.
