Tek Görüntü Süper Çözünürlük Uygulamaları İçin Görsel Kaliteyi İyileştirmeye Yönelik Yeni Bir Yaklaşım
Authors: ŞENALP Fatih Mehmet
Published: March 2023

Tek görüntü süper çözünürlük problemi, literatürde çeşitli derin öğrenme tabanlı teknikler kullanılarak kapsamlı çalışmalar yapılmıştır. Derin evrişimli ağlar tabanlı süper çözünürlük, çok sayıda pratik uygulama ile beraber hızla büyüyen bir ilgi alanı haline gelmiştir. Bununla birlikte derin öğrenme tabanlı ilk çalışmalar evrişimli sinir ağları tabanlı olup, tepe sinyal gürültü oranı odaklı çalışmalardır. Son yıllardaki çekişmeli üretici ağlar tabanlı geliştirilen modeller sayesinde görsel kaliteyi artırmak esas amaç olarak belirlenmiştir; fakat bu durum görüntü kalite metrikleri incelendiğinde görülmemektedir. Bu çalışmada ise ağın eğitimi sırasında kullanılan ağ kaybı için hem ortalama kare hata hem de algısal kayıp değerlerinden faydalanılmıştır. Ayrıca, üç farklı eğitim veri setinin birleşimi yeni bir eğitim veri seti olarak kullanılmıştır. Bu etmenlerin sonucunda hem görsel kalite artırılmış hem de görüntü kalite metrik değerlerinde ciddi bir artış yakalanmıştır. Ek olarak, yığın normalleştirme katmanları ağ mimarisine dahil edilmemiş ve bağlantı atlama tekniği kullanılarak derin ağ mimarisinin eğitim hızı artırılmıştır. Önerilen modelin başarı performansı literatürde yer alan önemli modeller ile karşılaştırılmıştır. Burada, tepe sinyal gürültü oranı ve yapısal benzerlik indeksi değerleri literatürde yaygın kullanılan üç farklı test veri seti için ayrı ayrı hesaplanmış ve değerlendirilmiştir. Elde edilen sonuçlar değerlendirildiğinde önerilen modelin diğer modellere göre daha başarılı olduğu ve daha kaliteli görüntüler oluşturduğu görülmektedir. Tüm bulgular değerlendirildiğinde önerilen modelin diğer modellere kıyasla hem başarı hem de eğitim hızı bakımından daha verimli bir model olduğu görülmektedir.

Published: March 2023

A large amount of genetic information is localized in microRNAs which are a class of non-coding RNAs formed from longer RNA precursors, usually having a length of 19-24 nucleotides and a specific hairpin structure. Although microRNA studies have been started relatively recently, there is no doubt that they play an important role in regulating gene expression at the post-transcriptional level in embryonic development, and are also involved in maintaining the normal functions of adult cells. For the first time, microRNA was discovered in the study of free-living nematodes Caenorhabditis elegans and then a new mechanism for suppressing expression using antisense RNA was discovered. MicroRNA may be part of protein-coding transcripts or may be located in the intergenic genome regions. Changes in the functional activity and number of microRNAs can lead to diseases such as oncological, cardiovascular, gynecological, and neurological. MicroRNA is also involved in the process of neurodegeneration and the development of mental diseases. Since part of the microRNA is specific to certain tissues and/or stages of development of the organism, microRNA molecules can be considered as a promising diagnostic tool. Among the advantages of these biomarkers are the possibility of detecting pathology in the latent stage, the low invasiveness of studies and resistance to destructive factors. At the same time, microRNAs can be detected in various biological fluids: blood serum, urine, seminal fluid, saliva, breast milk. Currently, the possibilities of using microRNAs in targeted therapy are widely discussed in connection with the possibility of regulating the expression of genes with undesirable properties or overexpression of microRNA inhibitors to prevent the negative effects of microRNAs that cause the development of the disease. The first part of the review discusses the historical aspect of the study of microRNAs, their mechanism of formation, the features of circulating microRNAs and the possible therapeutic effect of exogenous microRNAs coming from food on the human body.

Aim. To assess the prevalence of the left ventricle involvement and the features of the biventricular phenotype of arrhythmogenic cardiomyopathy in patients with pathogenic mutations in the PKP2 and DSP genes.

Material and methods. Three unrelated probands underwent a comprehensive molecular-genetic, clinical and instrumental examination, which included a 12-lead ECG, 24-hour ECG monitoring, transthoracic echocardiography, and cardiac magnetic resonance imaging with late gadolinium enhancement.

Results. The results of our clinical observations showed that in three studied patients with arrhythmogenic cardiomyopathy left ventricle involvement of various degree was found. The left ventricle damage was characterized by fibrous or fibro-fatty infiltration of the myocardium, as well as regional or global systolic dysfunction of different severity. The patients had pathogenic mutations c.1912C > T (p.Gln638*, rs397517012, rs397517012); c.1237C > T (p.Arg413*, rs372827156) in the PKP2 gene and a new probably pathogenic variant in the form of a c.3494delA deletion in the DSP gene. It was found that the mutation in the DSP gene was associated with a more pronounced systolic dysfunction and a greater percentage of fibrous replacement of the left ventricular myocardium compared with carriers of mutations in the PKP2 gene. All patients had life-threatening ventricular arrhythmias with the need for implantation of a cardioverter-defibrillator.

Conclusion. Our clinical observations have shown that in patients with biventricular arrhythmogenic cardiomyopathy, the detection of a mutation in the DSP gene is associated with a more pronounced systolic dysfunction and a higher percentage of fibrous replacement of the left ventricle myocardium compared with carriers of mutations in the PKP2 gene.
The Church, Prophetism and Ministry of the Prophets in Ghana
Authors: Amarkwei Charles
Published: March 2023

This paper tries to demonstrate that Christian prophetism is vital in fulfilling the mandate of the Great Commission. It employs both hermeneutical, descriptive, and analytical methods of doing constructive theology. It points out that prophetism is a creative work of God through Jesus Christ in the power of the Holy Spirit. Nonetheless, accompanying the creative and redemptive acts of prophetism is the tendency for it to attract or degenerate into such things as conflict, abuse, and unethical actions. The paper shows that both elements of creativity and degeneration could be traced to Ghanaian prophetism. Moreover, it advocates that proper theological education and law enforcement among others regarding prophetism could minimize the degeneration of prophetism for the rapid growth and expansion of Christian mission in Ghana.

Multicomponent Activity Cycles Using Hilbert–Huang Analysis
Authors: Velloso E. N. , Anthony F. , do Nascimento J.-D. , Silveira L. F. Q. , Hall J. , Saar S. H.
Published: March 2023

The temporal analysis of stellar activity evolution is usually dominated by a complex trade-off between model complexity and interpretability, often by neglecting the nonstationary nature of the process. Recent studies appear to indicate that the presence of multiple coexisting cycles in a single star is more common than previously thought. The correct identification of physically meaningful cyclic components in spectroscopic time series is therefore a crucial task, which cannot overlook local behaviors. Here we propose a decomposition technique that adaptively recovers amplitude- and frequency-varying components. We present our results for the solar activity as measured both by the sunspot number and the K-line emission index, and we consistently recover the Schwabe and Gleissberg cycles as well as the Gnevyshev–Ohl pattern probably related to the Hale cycle. We also recover the known 8 yr cycle for 61 Cygni A, in addition to evidence of a three-cycles-long pattern reminiscent of the Gnevyshev–Ohl rule. This is particularly interesting as we cannot discard the possibility of a relationship between the measured field polarity reversals and this Hale-like periodicity.
Nucleosynthesis in Outflows from Black Hole–Neutron Star Merger Disks with Full GR(ν)RMHD

Published: March 2023

Along with binary neutron star mergers, the inspiral and merger of a black hole and a neutron star is a predicted site of r-process nucleosynthesis and associated kilonovae. For the right mass ratio, very large amounts of neutron-rich material (relative to the dynamical ejecta) may become unbound from the post-merger accretion disk. We simulate a suite of four post-merger disks with three-dimensional general-relativistic magnetohydrodynamics with time-dependent Monte Carlo neutrino transport. We find that within 104

3 (∼200–500 ms), the outflows from these disks are very close to the threshold conditions for robust r-process nucleosynthesis. For these conditions, the detailed properties of the outflow determine whether a full r-process can or cannot occur, implying that a wide range of observable phenomena is possible. We show that on average the disk outflow lanthanide fraction is suppressed relative to the solar isotopic pattern. In combination with the dynamical ejecta, these outflows imply a kilonova with both blue and red components.
Mass and Color Dependence of the Hubble Spiral Sequence
Authors: Mengistu Petra , Masters Karen L.
Published: March 2023

In the classic Hubble spiral sequence, arm windiness correlates with bulge size; Sa type spiral galaxies with larger bulges also have the most tightly wound spirals. Exceptions to this have long been known, and in recent work using Galaxy Zoo morphologies no strong correlation was seen in a volume limited sample. In this Research Note, we explore the impact of galaxy mass and integrated color upon this correlation in the Galaxy Zoo sample, finding that bluer and lower mass spirals show the “expected” correlation; however, it becomes slightly negative for redder and/or more massive spiral galaxies.
L’étonnante histoire de l’inventaire de l’habitation Le Bonnet
Authors: Gentier-Lambert Élodie
Published: March 2023

Ayant eu connaissance de l’existence d’un inventaire d’une habitation appelée Le Bonnet, située à Saint-Domingue (actuelle Haïti) conservé aux archives départementales de Belfort sous la côte 1J1127, nous avons voulu comprendre le lien existant entre Belfort et l’esclavage colonial. Dans cette quête, il est apparu que l’habitation a, sur une courte période (1754-1772), pas moins de 8 propriétaires successifs ce qui interroge sur la viabilité de cette habitation. Cette histoire mouvementée a donné lieu à un mémoire de master soutenu à l’université de Franche-Comté.
Les ducs de Duras, gouverneurs de la Franche-Comté (1674-1789)
Authors: Farrugia Adrien
Published: March 2023

La notion de représentation politique, à travers la charge de gouverneur de province, tend à évoluer de façon significative entre le xvii e  et le xviii e  siècles. Le gouverneur représente l’autorité du souverain en un territoire donné. Pourtant, au xviii e  siècle l’absence de ce dignitaire dans son gouvernement invite à reconsidérer son rôle afin de mieux cerner l’ambivalence de l’institution. Le cas de la Franche-Comté présente pour cette question un champ d’étude intéressant. Dès l’été 1674, la province comtoise se voit attribuer un gouverneur : Jacques-Henri de Durfort duc de Duras. Bien que l’action de ce dernier dans son gouvernement soit notable, la monarchie manifeste la volonté de limiter sa présence en province. Le gouverneur finit par être absent dans son gouvernement au xviii e  siècle. Les figures de Jean-Baptiste de Durfort et Emmanuel-Félicité de Durfort en tant que gouverneur de la province comtoise, dans la seconde moitié du xviii e  siècle, permettent de mettre la lumière sur l’évolution de l’institution de gouverneur. Conséquence directe de son absence, le gouverneur cherche d’autres moyens d’inscrire son empreinte sur le territoire comtois. Mais surtout, ce sont les institutions comtoises qui cherchent à travers ce dignitaire un soutien auprès du souverain. Ces dernières donc, en sollicitant les ducs de Duras pour différentes raisons, offrent de voir comment évolue le rôle de représentation politique des gouverneurs. Désormais, ils ne se présentent plus comme les hommes du roi en province, mais davantage comme les hommes de la province auprès du roi.
Les poèmes de Vittorio Alfieri : de l’effusion lyrique au recueil
Authors: Zanardo Monica
Published: March 2023

L’article retrace la genèse des  Rime , recueil de poèmes de Vittorio Alfieri (1749-1803), en se concentrant notamment sur les réagencements par lesquels les poèmes, écrits au fil des années, sont distribués par l’auteur dans un ensemble cohérent. En s’appuyant sur l’analyse des brouillons, on montre que c’est précisément à travers la composition des différents éléments que l’auteur parvient à une « mise en récit » de ses poèmes, chacun d’entre eux contribuant à esquisser un véritable autoportrait en vers.
« Réunis pour la première fois » : composer les œuvres de poètes du XVII e siècle après la Révolution
Authors: Speyer Miriam
Published: March 2023

Au xix e  siècle, la bibliophilie mène à la redécouverte de poètes du xvii e  siècle dont les œuvres n’ont jamais été publiées en volume. Comblant cette « lacune » deux siècles plus tard, le travail d’édition, composition et recomposition à la fois, est loin d’être neutre. La (re-)constitution de l’œuvre du poète est en même temps (re-)constitution d’une figure d’auteur, celle-ci correspondant parfois moins aux faits historiques qu’au projet de son éditeur moderne. C’est ce que montre l’exemple des poètes Motin, Des Yveteaux et Lingendes.

Authors: Cheng Kai , Li Lixia , Du Yanmin , Wang Jiangtao , Chen Zhenghua , Liu Jian , Zhang Xiangsheng , Dong Lin , Shen Yuanyuan , Yang Zhenlin
Published: March 2023

Percutaneous puncture is a common medical procedure that involves accessing an internal organ or tissue through the skin. Image guidance and surgical robots have been increasingly used to assist with percutaneous procedures, but the challenges and benefits of these technologies have not been thoroughly explored. The aims of this systematic review are to furnish an overview of the challenges and benefits of image-guided, surgical robot-assisted percutaneous puncture and to provide evidence on this approach. We searched several electronic databases for studies on image-guided, surgical robot-assisted percutaneous punctures published between January 2018 and December 2022. The final analysis refers to 53 studies in total. The results of this review suggest that image guidance and surgical robots can improve the accuracy and precision of percutaneous procedures, decrease radiation exposure to patients and medical personnel and lower the risk of complications. However, there are many challenges related to the use of these technologies, such as the integration of the robot and operating room, immature robotic perception, and deviation of needle insertion. In conclusion, image-guided, surgical robot-assisted percutaneous puncture offers many potential benefits, but further research is needed to fully understand the challenges and optimize the utilization of these technologies in clinical practice.

The purpose of this study was to develop and validate an emergency medical technician (EMT) care patient satisfaction scale to measure patient satisfaction with prehospital emergency care. To date, patient satisfaction surveys of EMTs have been performed subjectively, e using each facility's questionnaire, without the use of a validated patient satisfaction scale. However, no specific scale has been devised to assess patient satisfaction with EMTs. The study population comprised patients who used an ambulance between November 2020 and May 2021 (N = 202). A survey instrument was administered to participants who provided informed consent. In the process of validating the patient satisfaction scale, an exploratory factor analysis (EFA) of construct validity was performed. The results of the EFA showed a factor structure consisting of five factors: “teamwork”, “explanation and communication”, “physical treatment and psychological support”, “quickness of transport”, and “environment in the ambulance”. In addition, domain and summary scores showed good internal reliability (Cronbach's range = 0.82–0.94). The patient satisfaction scale developed in this study was designed and validated considering the role of EMTs and patients' needs for prehospital care. This scale may be useful in the development of assessments and interventions to improve patient satisfaction with EMTs.

Uitrol van de functionaliteitseconomie in het Brussels Hoofdstedelijk Gewest: een stand van zaken
Authors: Ruwet Coline , Lohest François , Hoe Roxane De , Maréchal Kevin , Muylaert Coralie , Thiry Géraldine , Roman Philippe
Published: March 2023

La Région de Bruxelles-Capitale (RBC) s’est engagée, depuis 2016, à mettre la transition au cœur de sa stratégie économique. Parmi les modèles économiques prometteurs figure l’économie de la fonctionnalité (EF), par laquelle la vente de l’usage d’un bien est substituée à la vente du bien lui-même. Plusieurs vertus lui sont attribuées en matière de soutenabilité. Ainsi, la rétention de la propriété des biens par les entreprises inciterait ces dernières à choisir des produits durables. La mise à disposition d’un même bien pour divers usagers limiterait les quantités produites. L’EF catalyserait aussi l’ancrage local des systèmes productifs et de consommation. Pourtant, en RBC, le modèle de l’EF reste encore peu connu, mal compris et peine à se déployer. C’est pourquoi le présent article, issu d’une recherche de 4 ans sur l’EF en RBC, poursuit trois objectifs : 1) il dresse un panorama original de l’état actuel de l’EF en RBC et de la diversité des besoins auxquels l’EF pourrait répondre ; 2) il analyse les dispositifs institutionnels de soutien de l’EF en RBC, et 3) il s’interroge sur l’adéquation entre les dispositifs institutionnels de soutien à une économie soutenable en RBC et le déploiement de l’EF dans la Région. Il ressort de cette étude exploratoire que l’EF est encore peu présente, tant institutionnellement que dans le tissu économique bruxellois. Il semblerait dès lors pertinent de donner davantage de place au modèle de l’EF, en créant des espaces permettant à des acteurs économiques d’expérimenter le modèle et d’en évaluer les effets en termes de soutenabilité, de construire une vision commune et de définir les trajectoires de son déploiement.

Published: March 2023

Everyone today wants to detect disease early on, but because there aren't many patterns for the many diseases available, it's hard to do so. Because DNA sequences contain all the genetic data about organisms, which can be utilised by researchers to discover or treat diseases early on by developing new medications, using DNA sequences to extract patterns of disease can be very advantageous. The largest global collection of genomic sequences is made available by NCBI, but today the biggest worry is how to protect this enormous amount of data. One of the options is to encrypt these genetic sequences using blockchain technology. As a result, a study of the number of studies in this area as well as the demand for blockchain in healthcare has been conducted in this chapter. Additionally, surveys about research done in the field of DNA sequence classification are suggested along with recommendations for using classification of DNA sequences to detect disease earlier.

Optimizing a function helps solve challenging problems. Any optimization problem that can't be solved quickly utilizing deterministic approaches is hard. Metaheuristic optimization uses metaheuristics to discover optimum solutions. Meta and heuristic mean “higher level” and “solution;” using complicated approaches to address unsolvable problems.6G will replace 5G wireless networks. 6G networks' higher frequencies will boost their capacity and minimize latency. The 6G internet aspires for one-microsecond latency. This is 1,000 times faster at 1 millisecond.6G technology is expected to advance imaging, presence technologies, and location awareness. WSNs integrate hardware and software networks to monitor and record environmental variables and other observable quantities. Wireless sensor networks (WSN) are utilized commercially and domestically for effective communication.

On the Application of Quick Artificial Bee Colony Algorithm (qABC) for Attenuation of Test Suite in Real-Time Software Applications
Authors: Jeya Mala D.  , Prabha Ramalakshmi
Published: March 2023

Software testing plays a vital role during the software development process, as it ensures quality software deployment. Success of software testing depends on the design of effective test cases. To achieve the optimization of generated test cases, the proposed approach combines both global and local searches by means of intelligent agents which exhibit the behaviour of employed bees, onlooker bees, and scout bees in the qABC algorithm. The proposed qABC algorithm has key improvements over the basic artificial bee colony algorithm (ABC) in test optimization by reducing redundancy, filtering of test cases in each iteration and parallel working of the bees. Further, the fitness evaluation of the test cases is done by employing two test adequacy metrics namely path coverage and mutation score. Further, the experimental evaluation of qABC, GA, and the basic ABC based test cases is done using several case study applications. The result shows that qABC outperforms the other algorithms in terms of effectiveness of test cases in revealing the faults with less time and a smaller number of test cases.

Published: March 2023

While tariff barriers have drastically reduced around the world, non-tariff barriers, including demonstrating compliance with technical regulations, standards, and conformity assessment procedures, remain a significant obstacle to trade and could be particularly daunting for small and medium enterprises (SMEs). International standards have been recognized as an effective way to reduce technical barriers to trade (TBT). This research examines the impact of Canada's participation in international standards development (measured by technical committee/subcommittee participation) on SMEs' likelihood to export. Drawing on a national SME survey, results of the analysis showed that, after controlling for potentially confounding firm and owner attributes, Canada's participation in international standards development has a positive impact on Canada's exports and is associated with engaging more SMEs in international trade.
An unexpected and unusual cause of pulmonary hypertension in a patient with hypersensitivity pneumonitis: partial anomalous pulmonary venous connection causing pulmonary artery hypertension
Authors: Upadhya Pratap , Garg Shivam , A. Jeevanandham , Ponraj Nesamani Daniel , Wayez Ahmed
Published: March 2023

Partial anomalous pulmonary venous connection (PAPVC) occurs when any pulmonary vein, but not all, drains directly into the right atrium or its venous tributaries. PAPVC can very rarely present as an individual cause of pulmonary artery hypertension. Here we are presenting a case of a 41-year-old farmer with a history of exertional dyspnoea for the past three years, which increased over 6 months. Chest high-resolution computed tomography (HRCT) was suggestive of non-fibrotic hypersensitivity pneumonitis. Hence the patient was started on systemic steroids, with which the patient’s oxygen saturation improved. On 2D-ECHO, the right ventricle systolic pressure was 48+RAP. Right heart catheterization showed mean pulmonary artery pressure of 73 mmHG, PVR 8.7. On further evaluation, CTPA was done, which surprisingly revealed the left superior pulmonary vein draining into the left brachiocephalic vein.
Ocular manifestations of common pulmonary diseases - A narrative review
Authors: Singh Mamta , Deokar Kunal , Sinha Bibhuti Prassn , Keena Monika , Desai Govind
Published: March 2023

Ocular involvement can be a comorbidity of several pulmonary disorders. A knowledge of these manifestations is essential for early diagnosis and treatment. Hence, we aimed to review the common ocular manifestations of Asthma, COPD, sarcoidosis, obstructive sleep apnea and lung cancer. The ocular manifestations of bronchial asthma include allergic keratoconjunctivitis and dry eye. The inhaled corticosteroids used in the management of asthma can lead to cataract formation. COPD is associated with ocular microvascular changes due to chronic hypoxia and spill over of systemic inflammation into the eyes. However, its clinical significance is yet to be known. Ocular involvement is very common in sarcoidosis, seen in 20% of cases of pulmonary sarcoidosis. It can involve almost any anatomical structure of the eye. Studies have shown the association of obstructive sleep apnea (OSA) with floppy eye syndrome, glaucoma, nonarteritic anterior ischemic optic neuropathy, keratoconus, retinal vein occlusion and central serous retinopathy. However, though association has been established, causality remains to be proven. The effect of positive airway pressure (PAP) therapy used in the treatment of OSA on the above ocular conditions is yet to be known.  The PAP therapy can itself lead to irritation and dry eyes. Lung cancer can involve the eyes by direct invasion of nerves, ocular metastasis or as a part of paraneoplastic syndrome. The purpose of this narrative review is to raise awareness about the association between ocular and pulmonary disorders to facilitate early detection and treatment of these conditions.
Comparison of the Patient State Index and Bispectral Index in Patients with Complex Regional Pain Syndrome Undergoing Ketamine Infusion Therapy
Authors: Lee Ki Hwa , Lee Sang Eun
Published: March 2023

It is important for clinicians to perform a continuous comprehensive assessment of the depth of sedation, including the use of processed electroencephalographic monitors and the review of clinical signs. Ketamine is a safe anesthetic and sedative traditionally used in the clinical practice. It possesses analgesic, anti-inflammatory, and antidepressant activities and is used as a therapeutic agent in intractable pain. In this case series, we present a comparison between patient state index (PSI) and bispectral index (BIS) in a sample of eight patients with complex regional pain syndrome undergoing ketamine infusion therapy. Blood pressure, heart rate, respiratory rate, end-tidal carbon dioxide, and oxygen saturation were all noted, as well as the PSI and BIS values. The PSI and BIS readings were not recorded when the artifact was larger than 50%. Four patients (50%) received intravenous midazolam 5 mg when their agitation or movement could not be managed by the clinicians’ verbal instructions. In five patients (62%), 20 min after the ketamine infusion began, deep drowsiness was attained. There are fewer research studies on PSI than there are on BIS. We found that PSI values did not match BIS values. This case series could help clinicians select an appropriate course of action for ketamine sedation in individual patients.

Introduction:

Pressure-controlled volume-guaranteed (PCV-VG) mode has the advantage of both volume-controlled (VCV) and pressure-controlled ventilation (PCV). Our objective is to compare gaseous exchange and lung dynamic compliance (C
dyn) after pneumoperitoneum and just before desufflation in VCV, PCV, and PCV-VG mode in laparoscopic cholecystectomy (LC).

Materials and Methods:

A total of 105 patients undergoing LC under general anesthesia were randomly distributed to group V (received VCV), group P (PCV), and group PV (PCV-VG) as mode of ventilation. Two arterial blood samples were taken for blood gas analysis: after the pneumoperitoneum (T1) and right before abdominal desufflation (T2). Arterial partial oxygen pressure (PaO2) and carbon dioxide (PaCO2) levels, oxygen saturation (SpO2) and end-tidal carbon dioxide were compared at these two points of time between the groups.

Results:

C
dyn was higher in group P (43.21 ± 4.4 mL/cmH2O) compared with group V (39.18 ± 3.2 mL/cmH2O) and PV (40.37 ± 2.45 mL/cmH2O) at T2 (P < 0.001). PaO2 was significantly higher (P < 0.001) in group P (197.50 ± 17.29 mm Hg) at T2 compared with group V (178.90 ± 23.7 mm Hg) and PV (183.47 ± 22.99 mm Hg). Furthermore, PaCO2 was also significantly higher in Group P (40.19 ± 2.92 mm Hg) compared with group V (32.57 ± 2.09 mm Hg) and group PV (34.14 ± 3.27 mm Hg).

Conclusion:

PaO2 and dynamic compliance are higher in pressure-controlled mode but, high PaCO2 in pressure-controlled mode indicates inadequate ventilation. Therefore, pressure controlled volume guaranteed mode can be considered as a favorable ventilation strategy during LC because dynamic compliance and PaO2 are higher than volume controlled ventilation and PaCO2 is significantly less than pressure controlled mode.
Interfollicular Hodgkin’s lymphoma: A diagnostic challenge for pathologists
Authors: Vijay Maneesh K. , Sethi Neha
Published: March 2023

Interfollicular Hodgkin’s lymphoma (IFHL) is a rare pattern of classical Hodgkin’s lymphoma (CHL) showing reactive follicular hyperplasia with involvement of the interfollicular area by HL. Two cases are reported in this study having primary IFHL out of total of 500 cases of CHL reported at our center. Diagnosis of IFHL was made on the basis of morphological and immunohistochemical features. As they represent an early stage of the disease, their identification and awareness s very important to get proper treatment at its earliest. This variant is very unusual and is diagnostically challenging for pathologists.
The index bundle for selfadjoint Fredholm operators and multiparameter bifurcation for Hamiltonian systems
Authors: Skiba Robert , Waterstraat Nils
Published: March 2023

The index of a selfadjoint Fredholm operator is zero by the well-known fact that the kernel of a selfadjoint operator is perpendicular to its range. The Fredholm index was generalised to families by Atiyah and Jänich in the sixties, and it is readily seen that, on complex Hilbert spaces, this so-called index bundle vanishes for families of selfadjoint Fredholm operators as in the case of a single operator. The first aim of this note is to point out that, for every real Hilbert space and every compact topological space

X

, there is a family of selfadjoint Fredholm operators parametrised by

X\times S^1

which has a non-trivial index bundle. Further, we use this observation and a family index theorem of Pejsachowicz to study multiparameter bifurcation of homoclinic solutions of Hamiltonian systems, where we generalise a previously known class of examples.
Kvantitativni postopek identifikacije grbinastih travnikov na območju Triglavskega narodnega parka
Authors: Stefanovski Sašo , Lampič Barbara
Published: March 2023

Na območju Triglavskega narodnega parka zasledimo poseben tip travnikov – grbinaste travnike. Zaradi človekove dejavnosti imajo grbinasti travniki ne le naravovarstveno, ampak tudi kulturno vrednost. Zato je od leta 2004 v Programu razvoja podeželja (PRP) vzpostavljen sistemski ukrep za ohranjanje grbinastih travnikov. Kmetje so za njihovo vzdrževanje upravičeni do izravnalnih plačil, a je ta podpora nizka, med manj poznanimi in zelo slabo uveljavljenimi. Uradni prostorski sloj grbinastih travnikov je, kljub terenski preveritvi in nadgradnji v letu 2021, necelovit in deloma pomanjkljiv. Namen članka je prikaz nove metode oziroma razvoja kvantitativnega postopka identifikacije grbinastih travnikov na območju Triglavskega narodnega parka. Omejitev postopka je, da ni neposredno uporaben za zaznavanje grbinastih travnikov brez naknadnega terenskega ali digitalnega pregleda. Z njegovo uporabo smo predstavili možnost učinkovite nadgradnje obstoječega uradnega prostorskega sloja grbinastih travnikov.

Introduction: WHO estimates 422 million cases of diabetes mellitus worldwide. Mozambique has the second-highest mortality related to DM in the African region.

Objectives: To provide data about a DM care service in Mozambique and to evaluate early outcomes of treatment.

Methods: The new patients diagnosed with DM in a two-years period in a health centre in Maputo (Mozambique) were included in a retrospective cohort study. Fasting blood glucose (FBG), waist circumference (WC) and BMI were collected at baseline and after three months.

Results: 188 patients were enrolled. Median BMI, WC and FBG at baseline were respectively 28 kg/m2(Inter Quartile Range [IQR]23.4-31.8), 98cm (IQR 87-105) and 209mg/dL (IQR 143-295). A non-pharmacological intervention was prescribed for six patients, while 182 patients received metformin 500 mg b.i.d. FBG was significantly reduced at control (226[±103.7]mg/dL vs 186[±93.2]mg/dL, p<0.000); however, glycemic control was reached in 74 patients (39.4%); not controlled patients changed regimen. Elderly patients had a higher glycemic control (adjusted Odds Ratio 2.50, 95% CI 1.11-5.06, p=0.002).

Conclusion: Strategies for early detection of scarce glycemic control are feasible in Mozambique and could lead to prompt regimen switch; an invasive therapeutic approach could be preferable in selected cases to achieve control.

Background: The psychological problems associated with facial trauma may sometimes pose additional health concerns for the injured patient. Understanding the gaps in the Oral and Maxillofacial surgeons’ (OMFS) awareness of patient in need of specialist mental health intervention is important in ensuring holistic care for the trauma patient.

Objectives: To determine the knowledge, practices and self-assessed level of competence of Nigerian Oral maxillofacial surgeons/trainees regarding psychological problems associated with facial trauma and to determine their perceived need for training in assessment of psychological consequences following facial trauma.

Methods: A cross-sectional study was conducted in which a web-based structured questionnaire was sent to Oral and maxillofacial surgeons and trainees.

Results: Majority of respondents (85.2%) had encountered psychological problems in patients who have sustained facial trauma. Half (50.6%) of OMFS / trainees had high level of knowledge regarding psychological problems associated with facial trauma; depression, anxiety, post-traumatic stress disorder, body image disorder and acute stress syndrome were the five most common trauma related psychological problems mentioned. More respondents reported low level of competence in conducting mental state examination when compared to other skill sets. In-unit counselling was reported as the method of intervention by majority (69.1 %), followed by referral to the mental health specialists (17.3%). More than one third (40.7%) of OMFS were extremely interested in undergoing additional training in the psychological assessment of patients who have sustained facial trauma.

Conclusion: Nigerian Oral and maxillofacial surgeons frequently encounter psychological problems in patients with traumatic facial injuries. Notwithstanding their perceived self-assessed low level of competence in psychological assessment of trauma patients, objective assessment revealed a relatively high level of knowledge of psychological problems that can affect the facial trauma patient with many indicating a high perceived need for additional training in the psychological assessment of facial trauma patient. There is a need for incorporating psychological assessment into the management to ensure holistic care of trauma patients.
