Alzheimer's disease affects irreversible brain damage cells that control memory and reasoning. Owing to comparable brain patterns and pixel intensities, diagnosing Alzheimer's disease in elderly persons is challenging and necessitates a highly discriminative feature representation for classification. These representations can be learned from data using deep learning algorithms. To address these issues, previous research looks into the usefulness of rs-fMRI for multi-class classification of Alzheimer's disease and its phases, such as CN, SMC, EMCI, MCI, LMCI, and AD. To improve the image quality, some pre-processing procedures were used, including brain extraction, motion correction, intensity, normalization, spatial smoothing, high pass filtering, spatial normalizing, image registration, and 4D to 2D conversion. And then Alzheimer’s disease multi stage classification was done by using Alex net and Resnet convolutional neural network. Existing research, on the other hand, hasn't concentrated on texture feature extraction. ResNet has proven to be successful in a wide range of applications, but one major drawback is that training a deeper network takes several days, making it unsuitable for real-world applications. Medical records, whether housed in health information systems, the cloud, etc. are critical. For such records, privacy and security must be ensured using encryption and authentication techniques that are not currently in use. To prevent these issues, this study used pre-processing techniques as brain extraction, motion correction, intensity, normalization, spatial smoothing, high pass filtering, spatial normalizing, image registration, and 4D to 2D conversion to improve image quality. And then texture feature extraction will be done by utilizing gray level co occurrence matrix (GLCM). Alzheimer's disease multi stage classification will be computed based on Alexnet and Googlenet models for Neuroimaging data is attained from Alzheimer’s disease Neuroimaging Initiative (ADNI) dataset. And then all Medical records will be encrypted using Modified Advanced Encryption Standard (MAES) to provide security and then stored in cloud. Experiments show that the suggested model is effective with respect to encryption time, precision, recall, and accuracy.

Introduction : Le taux de syphilis infectieuses continue d'augmenter chez les femmes en Colombie-Britannique et au Canada, ce qui soulève des préoccupations quant à l'augmentation de l'incidence de la syphilis congénitale. Nous avons caractérisé les cas de syphilis chez les femmes de la Colombie-Britannique afin de déterminer les possibilités de prévenir la syphilis et d'optimiser ses soins. Méthodes : Tous les cas de syphilis infectieuse diagnostiqués en Colombie-Britannique entre le 13 mars 2018 et le 31 décembre 2020 et s'identifiant comme femme ont été examinés. Des données démographiques, des facteurs de risque et des conditions concurrentes ont été recueillis auprès d'un système de surveillance provincial. Des analyses de sous-groupes comparant des cas avec et sans instabilité du logement, consommation de substances, maladie mentale et une infection sexuellement transmissible récente (ITS) ont été effectuées afin de comprendre les différences entre ces sous-groupes. Les associations statistiques ont été calculées au moyen de tests khi carré ou de tests t. Résultats : Au cours de cette période, 226 cas de syphilis infectieuse féminine ont été déclarés en Colombie-Britannique : 38 (16,8 %) en 2018; 74 (32,7 %) en 2019; et 114 (50,4 %) en 2020. L'âge moyen était de 32 ans (intervalle de 15 à 75 ans). Parmi les personnes qui ont déclaré des conditions concomitantes, la plupart des cas ont connu une instabilité du logement (71,1 %), une consommation de substances (68,2 %) et une maladie mentale (83,9 %), alors que 42,9 % avaient une ITS récente. Les cas qui ont déclaré une instabilité du logement ou une consommation de substances étaient beaucoup plus susceptibles d'avoir récemment eu une ITS, avoir des antécédents de vie dans la rue, de rapports sexuels transactionnels, une maladie mentale et une aide au revenu (tous p < 0,01). Conclusion : Nos résultats soulignent l'importance de favoriser un environnement propice aux soins de la syphilis. Des services simultanés pour soutenir les personnes atteintes de syphilis ainsi que l'instabilité du logement, la consommation de substances et la maladie mentale pourraient aider à prévenir la syphilis et à améliorer le bien-être.
Syphilis in Ottawa: An evolving epidemic
Authors: Orser Lauren , MacPherson Paul , O’Byrne Patrick
Published: February 2022

Background: The incidence of infectious syphilis in Canada has declined throughout the latter decades of the last century; however, in Ottawa, an upsurge in new cases began in 2001. The local epidemic continues to involve predominantly gay, bisexual and other men who have sex with men (gbMSM), but in recent years, has expanded further into heterosexual populations. This has coincided with an increase in the number of pregnant women testing positive for syphilis on antenatal screening. The aim of this study is to understand the changing epidemiology in infectious syphilis cases diagnosed in Ottawa to strengthen primary care management and public health response. Methods: Surveillance data from the Ontario Ministry of Health were used to describe the evolving epidemiology of infectious syphilis in the Ottawa region from 2010 to 2019, including a comprehensive chart review of cases from 2015–2019. Results: The number of cases of infectious syphilis in Ottawa rose from 50 cases in 2010 to 171 cases in 2019. These rates were consistently high among males, and increased from 10.9/100,000 in 2010 to 30.9/100,000 in 2019. The rates among females, in comparison, increased from 0.4/100,000 in 2010 to 3.2/100,000 in 2019, with corresponding increases during antenatal screening (with no congenital syphilis cases to date). Conclusion: As the syphilis epidemic continues to evolve in Ottawa, ongoing surveillance plays a crucial role. Public health resources must address the needs of populations already impacted but at the same time be flexible enough to respond to changes in trends and support clinicians providing care to populations where the epidemic is emerging.
Cas de syphilis à Ottawa : une épidémie en évolution
Authors: Orser Lauren , MacPherson Paul , O’Byrne Patrick
Published: February 2022

Contexte : L’incidence de la syphilis infectieuse au Canada a diminué au cours des dernières décennies. Cependant, on observe une augmentation du nombre de nouveaux cas depuis 2001 à Ottawa. L’épidémie locale touche principalement des hommes gais, bisexuels et autres hommes ayant des relations sexuelles avec des hommes (gbHARSAH), mais ces dernières années, elle s’est étendue à des populations hétérosexuelles. La propagation a coïncidé avec une augmentation du nombre de femmes enceintes ayant obtenu un résultat positif au test de dépistage de la syphilis lors du dépistage prénatal. Cette étude vise à comprendre l’évolution de l’épidémiologie des cas de syphilis infectieuse diagnostiqués à Ottawa afin de renforcer la gestion des soins primaires et l’intervention en santé publique. Méthodes : Des données de surveillance du ministère de la Santé de l’Ontario ont été utilisées pour décrire l’évolution de l’épidémiologie de la syphilis infectieuse dans la région d’Ottawa de 2010 à 2019, notamment un examen complet des dossiers des cas de 2015 à 2019. Résultats : Le nombre de cas de syphilis infectieuse à Ottawa est passé de 50 cas en 2010 à 171 cas en 2019. Ces taux étaient toujours élevés chez les hommes et sont passés de 10,9/100 000 habitants en 2010 à 30,9/100 000 habitants en 2019. En comparaison, les taux chez les femmes sont passés de 0,4/100 000 habitantes en 2010 à 3,2/100 000 habitantes en 2019, avec des augmentations correspondantes pendant le dépistage prénatal (aucun cas de syphilis congénitale à ce jour). Conclusion : La surveillance continue joue un rôle crucial alors que l’épidémie de syphilis continue d’évoluer à Ottawa. Les ressources en santé publique doivent répondre aux besoins des populations déjà touchées, en plus d’être suffisamment souples pour réagir aux changements de tendances et appuyer les cliniciens qui fournissent des soins aux populations touchées par l’épidémie.
A descriptive study of syphilis testing in Manitoba, Canada, 2015–2019
Authors: Shaw Souradet , Plourde Pierre , Klassen Penny , Stein Derek
Published: February 2022

Background: In 2018, Manitoba had the highest reported rate of infectious syphilis in Canada, at over three times the national average. Infectious syphilis in Manitoba is centred on young, marginalized heterosexual couples in Winnipeg’s inner-city. Subsequently, a public health crisis involving congenital syphilis emerged in Manitoba, just prior to the coronavirus disease 2019 pandemic. Testing and screening (in the case of pregnancy) for syphilis is thought to be an effective measure to reduce the incidence of syphilis and its sequelae. The aim of this study is to describe syphilis testing practices in the general population and amongst pregnant women, during a period of shifting syphilis epidemiology. Methods: We used population-based syphilis testing data from Cadham Provincial Laboratory (Winnipeg, Manitoba) for 2015 to 2019. Directly age-standardized rates are reported, and Poisson regression used to model the determinants of testing rates. Rates of prenatal screening are also reported. Results: From 2015 to 2019, a total of 386,350 individuals were tested for syphilis. The rate increased annually, from 462 per 10,000 population in 2015 to 704 per 100,000 in 2019, while the female-to-male ratio decreased from 1.8 to 1.6. Prior to 2019, the majority of pregnant women (approximately 60%) were screened once, during the first trimester; however, 2019 saw more women having more than two tests during the course of their pregnancy. Conclusion: An overall increase in the number of individuals tested was observed, reflecting the increased rate of syphilis in Manitoba. Prenatal screening patterns shifted in 2019, likely in response to rising congenital syphilis numbers.

Published: February 2022

Contexte : Le Nunavut, territoire qui fait partie de l’Inuit Nunangat, est une vaste région dans le nord du Canada qui abrite une population de plus de 38 000 personnes. La majorité de la population (85 %) s’identifie comme Inuit. Le Nunavut a connu une hausse importante du nombre de cas de syphilis infectieuse dans sa population hétérosexuelle depuis 2012. La gestion des maladies transmissibles, notamment la syphilis, est difficile en raison du roulement élevé du personnel et des longs délais de transport des spécimens. Les déterminants sociaux de la santé sont également des facteurs contributifs importants. Cette étude vise à décrire l’épidémiologie et les éléments du programme sur la syphilis infectieuse de 2012 à 2020 dans le but de mettre en évidence des interventions qui pourraient s’avérer bénéfiques. Méthodes : La syphilis est une maladie à déclaration obligatoire au Nunavut, et tous les cas sont signalés au ministère de la Santé du territoire. Les cas ont été déclarés par un médecin consultant. Les données ont été analysées et publiées dans des rapports publics dans le cadre du programme de santé publique. Résultats : De 2012 à 2020, 655 cas de syphilis infectieuse ont été signalés, dont 53 % chez des femmes. Les taux d’infection étaient les plus élevés chez les personnes âgées de 20 à 39 ans. Les cas déclarés au cours de cette période variaient considérablement selon la région géographique, et la majorité des cas infectieux ont été signalés dans la région de Kivalliq. Malgré 48 cas signalés pendant la grossesse, il n’y a eu aucun cas confirmé de syphilis congénitale. Le personnel du programme a cerné les forces des interventions ainsi que les besoins continus, comme les ressources en langage clair disponibles dans plusieurs langues. Conclusion : Malgré les défis logistiques liés à la gestion de la syphilis dans le territoire, les résultats globaux ont été positifs, et aucun cas congénital confirmé n’a été identifié. Nous attribuons cela à un effort coordonné de multiples partenaires, notamment des interventions clés d’infirmières de la santé publique et de représentants de la santé communautaire.
Exploring management of antenatally diagnosed fetal syphilis infection
Authors: Rosenthal Margot , Poliquin Vanessa
Published: February 2022

Background: The incidence of syphilis among Canadian women of childbearing age has risen dramatically in the past decade, with a resurgence of infants born with congenital syphilis. While guidelines exist to guide maternal infection during pregnancy, there is little evidence available to guide management in situations where the developing fetus is found to be severely affected. Case review: Our patient presented in the second trimester of her pregnancy as syphilis contact. Positive serologic tests (venereal disease research laboratory titre of 1:64) and a chancre suggested primary infection. Ultrasound demonstrated a fetus at 19+3 weeks gestation with hydrops fetalis and a markedly abnormal brain. Amniocentesis confirmed congenital syphilis infection on polymerase chain reaction testing. After nine days of intravenous penicillin G, the fetal status had worsened, and the family ultimately chose a medical termination of the pregnancy. Discussion: Evolving ultrasound technology has allowed us to identify severely affected fetuses, who may historically have been delivered stillborn. Following routine syphiliotherapy with benzathine penicillin, these abnormal ultrasound features may take weeks or months to reverse, which poses a challenge in prognostication and counselling. Case reports data suggests intensive treatment with intravenous penicillin may be effective in severe cases where fetal hydrops is present. Conclusion: This case highlights the potential morbidity of fetal syphilis infection and underscores the paucity of current literature. Information sharing will be essential to build a modern knowledge base on treating this ancient disease.
The flagging features of the Sysmex XN-10 analyser for detecting platelet clumps and the impacts of platelet clumps on complete blood count parameters
Authors: Xu Peng , Fang Kui , Chen Xiling , Liu Yangruiqi , Dong Zheqing , Zhu Ji , Lu Keda
Published: February 2022

Objectives

Platelet clumps present in anticoagulant specimens may generate a falsely decreased platelet count and lead to an incorrect diagnosis. A clear understanding of the ability of a haematology analyser (HA) to detect platelet clumps is important for routine work in the clinical laboratory.

Methods

Citrate-anticoagulated whole-blood samples were collected from various patients as a negative group. Adenosine diphosphate (ADP)-induced platelet aggregation was performed on those negative samples to mimic platelet-clump-containing (positive) samples. The ‘platelet clumps’ and ‘platelet abnormal’ flags generated by the Sysmex XN-10 instrument were used to assess the flagging performance of this HA and demonstrate its flagging features. The complete blood count (CBC) results of paired negative and positive samples were compared to evaluate the impact of platelet clumps on the CBC parameters.

Results

A total of 187 samples were eligible for this study. The total accuracy, sensitivity, and specificity of the platelet clumps flag were 0.786, 0.626, and 0.947, respectively. The total accuracy, sensitivity, and specificity of the platelet abnormal flag were 0.631, 0.348, and 0.914, respectively. A separate assessment focusing on the positive samples with low platelet counts showed that the total sensitivities of the platelet clumps and platelet abnormal flags were 0.801 and 1.000, respectively. Platelet clumps may interfere with the leukocyte count and with platelet and erythrocyte indices.

Conclusions

Platelet clumps can influence not only platelet indices but also leukocyte and erythrocyte counts. The Sysmex XN-10 instrument is sensitive to positive samples with low platelet counts but insensitive to those with high platelet counts.
Influence of Nb content on mechanical behavior and microstructure of Ti–Nb alloys
Authors: Wang Xuanli , Zuo Shungui , Wang Gaishi , Cao Jun , Zhang Yuqi , Jin Mingjiang
Published: February 2022

The effect of Nb content on the mechanical behavior of Ti-(20, 25, 30) at.% Nb alloys has been investigated. Results show that the storage modulus, the tensile strength and elongation at room temperature decrease with increasing Nb content. The Ti-20Nb and Ti-25Nb alloys show double-yielding behavior and they exhibit higher work hardening rate than the Ti-30Nb alloy. The Ti-20Nb alloy deforms by stress-induced β → α″ transformation and the reorientation of the α″ phase. While the Ti-25Nb alloy deforms by stress-induced martensitic transformation and deformation bands that are devoid of ω phase. The Ti-30Nb alloy, which has the highest β phase stability, deforms in a localized mode mainly by dislocation slip. The “marble-like” deformation microstructure previously reported in “gum metal” was observed in severely deformed Ti-25Nb and Ti-30Nb alloys.
Predictors associated with new nursing faculty’s intent to leave nursing academia: teaching preparation in doctoral program, institutional supports, and job satisfaction
Authors: Lee Young-Me , Aquino Elizabeth , Bishop-Royse Jessica , Spawn Nadia , Webber-Ritchey Kashica J.
Published: February 2022

Objectives

The purpose of this study was to examine the relationships among demographics, doctoral teaching preparation, nurse faculty institutional support, faculty job satisfaction, and intent to leave current nursing academic position in PhD- and DNP-prepared faculty.

Methods

Using a survey research design, invitations to a Qualtrics survey were emailed to nursing program directors. Independent samples t-tests and logistic regression models were used to determine the nature of the relationships.

Results

In total, 149 participants completed the survey. Degree type, age, and job satisfaction were significant predictors related to intent to leave nursing academia. Doctoral program teaching preparation and institutional support were not statistically associated with intent to leave nursing academia.

Conclusions

Findings suggest older age, PhD-prepared faculty, and job dissatisfaction were significant factors influencing decisions to leave nursing academia among the doctoral prepared new nursing faculty. Efforts to retain or increase the number of nurse faculty must be prioritized.
Humor in intercultural interaction: A source for misunderstanding or a common ground builder? A multimodal analysis
Authors: Ladilova Anna , Schröder Ulrike
Published: February 2022

The present paper explores three situations of conversational humor in which not only gesture and prosody but also code-switching play a role in the process of co-construction of humor among participants in an intercultural interaction. Despite the long tradition of studying humor in interaction, there has been little research so far which includes gesture – especially manual gesture – from an embodiment perspective and concurrently draws attention to the intercultural impact of humor, including moments of code-switching. By looking at multi-party interactions between German and Brazilian speakers from a multimodal perspective, we will show how different semiotic resources such as gaze, posture, head and hand gesture, as well as prosody and code-switching are displayed in order to construct humor. Our aim is to reveal the interplay and complexity of the communicative resources in the co-construction of humor by presenting three examples with different degrees of successful humor: While the conversational humor is only understood by the German co-participants in the first example, in the second example, the humor is co-constructed successfully by the German and Brazilian participants. Yet the last example reveals that the humor is understood by everybody but taken up differently what could also be related to the institutional context in which the sequence is embedded.
Evaluating the performance of elite level volleyball players
Authors: Fellingham Gilbert W.
Published: February 2022

Evaluation of individuals in a team sport setting is inherently difficult. The level of play of one individual is fundamentally tied to the level of play of the teammates. One way to think about evaluation of individuals is to ‘insert’ the posterior distribution of the parameter that measures individual play into an ‘average’ team, and see how the probability of success (or failure) changes. Using a Bayesian hierarchical logistic model, we can estimate both the average contribution to success of various positions, and the individual contribution of all the players in that position. In this paper, we use data from the 2018 World Championships in Volleyball to model both the position played and the players within each position. Using both the posterior distributions for the mean performance of the different positions, and the posterior distributions for the individual players, we can then estimate the change in the number of points scored for a team with a change from an average player to the individual under consideration. We compute both the points scored above average per set (PAAPS) and the points scored above average per 100 touches (PP100) for 168 men and 168 women playing five different positions. Contributions of the various position groups and of individual players within each position are evaluated and compared.
Ereignisbasierte Weißlichtinterferometrie (eCSI)
Authors: Schober Christian , Pruss Christof , Herkommer Alois
Published: February 2022

In diesem Beitrag wird ein scannendes, ereignisbasiertes Weißlichtinterferometriemesssystem (eCSI) in Verbindung mit der Nanomess- und Positioniermaschine NPMM-200 vorgestellt. Die scannende Kurzkohärenzinterferometrie wird in der Forschung und Industrie zur Vermessung von Form und Strukturen mit einer interferometrischen Auflösung und einem hohen Messbereich durch die Bestimmung der interferometrischen Streifenordnung aus der Kohärenzfunktion verwendet. In herkömmlichen Systemen wird zur Scanbewegung ein Piezoaktuator verwendet, der den Referenzspiegel oder das Objektiv relativ zum Prüfling verschiebt. In diesem System wird der Piezoaktuator durch die NPMM-200 ersetzt, was einen Scanbereich von 200 × 200 × 25 mm3 ermöglicht. Um den anfallenden großen Datenmengen in diesen Scanbewegungen entgegenzuwirken, wird das neuartige Konzept eCSI verwendet. Dabei wird im Vergleich zu einem herkömmlichen Kurzkohärenzinterferometer ein ereignisbasierter Sensor verwendet. Dieser registriert anstatt eines Frames einen kontinuierlichen Informationsstrom über die Änderungen der Intensitäten an den jeweiligen Pixeln. Bleibt die Intensität konstant, liefert der Sensor keine neuen Signale, was eine effizientere Ausnutzung der Bandbreite ermöglicht. Zu Beginn des Beitrags wird das Messsystem in Verbindung mit der NPMM-200 beschrieben. Dann wird die Signalgenerierung unter Verwendung einer ereignisbasierten Kamera erläutert. Im Anschluss daran werden experimentelle Ergebnisse an einem Tiefeneinstellnormal und einem Silizium-Kalibriertarget gezeigt und analysiert. Diese zeigen eine exzellente Übereinstimmung mit den kalibrierten Werten.
Indirect Nuclear Spin-Spin Coupling Constants nJ(11B, 1H) and nJ(11B, 11B) in Some Boron Hydrides - Density Functional Theory (DFT) Calculations
Authors: Wrackmeyer Bernd
Published: February 2022

Indirect nuclear spin-spin coupling constants J(11B,1H) and J(11B, 11B) in neutral and anionic boron hydrides 1- 17, calculated at the B3LYP/6-311+G(d,p) level of theory, are in good agreement with experimental data if available. This is shown for [BH4]
−
(1), B2H6 (2), B4H10 (3), B5H9 (4), or [B2H7]−(12). The calculations can be used to obtain values for those coupling constants for which experimental information is hardly accessible. This applies to complex spin systems involving the quadrupolar 11B nuclei such as in [B6H6]2−

The experimental 11B NMR spectrum reported in the literature for the dianion 6does not resemble the spectrum predicted on the basis of the calculated coupling constants.
Syntheses, Structures and Vibrational Spectroscopy of Some Adducts of Copper(I) Cyanide with Pyridine Bases
Authors: Bowmaker Graham A. , Lim Kevin C. , Skelton Brian W. , White Allan H.
Published: February 2022

Synthetic and room temperature single crystal X-ray structural characterizations are recorded for adducts of copper(I) cyanide formed by crystallization of copper(I) cyanide from (unidentate) pyridine (‘py’) bases L, of 1:2 (L = py; new phase), 1:1.5 (L = 2-methylpyridine, ‘2mp’) and 1:1 (L = quinoline, ‘quin’) stoichiometries. All are single-stranded polymers, with successive copper atoms linked by single linear cyanide bridges (C,N disordered, individual components not resolved), with four- or three-coordinate N2Cu(CN)2 or NCu(CN)2 copper environments in the 1:2 and 1:1 adducts, these alternating in the 1:1.5 (2:3) adduct. The present and previous related studies providing a basis for a systematic survey of their vibrational spectroscopy. The IR spectra of the infinite polymers show bands that are assigned to vibrations of the CuCN chains in these complexes: ν(CN), ν(CuC/N) (the CuC/CuN stretching mode, involving vibration of the CN group between its two neighbouring Cu atoms), δ (CuCN) (the restricted rotation of the CN group), and δ (NCuC) (the counter-vibration of the Cu substructure against the CN substructure). Gravimetric and vibrational spectroscopic studies following loss of the base molecules from these complexes show that ligand removal occurs in several stages via a series of well-defined adducts, some of which have unusual stoichiometries and structures. Conversely, solid CuCN may be “activated” towards adduct formation by prior reaction with pyridine bases.
Syntheses, Structures and Vibrational Spectroscopy of Some Mixed Pyridine/Triphenylphosphine Adducts of Copper(I) Cyanide
Authors: Bowmaker Graham A. , Hart Robert D. , Skelton Brian W. , White Allan H.
Published: February 2022

Single crystal room temperature X-ray structure determinations are described for three adducts formed between copper(I) cyanide, pyridine (‘py’) and triphenylphosphine of (p : q : r =) 1:1:1, 1:1.5:0.5 and 1:0.5:2 (plus py hemisolvate) stoichiometry. The latter is binuclear [(Ph3P)2(py)Cu(μ- CN)Cu(PPh3)2(CN)]. py; the others are linear polymers with . . .Cu(μ-NC)Cu(μ-NC)Cu. . . spines with four-coordinate copper atoms, the coordination sphere of every copper atom in the first being completed by pendant py and Ph3P ligands, while the second has those of alternate copper atoms coordinated by a pair of py ligands. Assignment of bridging CN in all cases is crystallographically ambiguous. The IR spectra of the infinite polymeric complexes show bands that are assigned to vibrations of the CuCN chains in the complexes: ν(CN), ν(CuC/N) (the CuC/N stretching mode, involving vibration of the CN group between its two neighbouring Cu atoms), δ (CuCN) (the restricted rotation of the CN group) and δ (NCuC) (the counter vibration of the Cu substructure against the CN substructure). The ν(CN) and ν(CuC/N) frequencies show correlations with the Cu-C/N bond lengths that are similar in form to those recently established for a range of AgCN complexes.
Syntheses, Structures and Vibrational Spectroscopy of Some Adducts of Copper(I) Cyanide with Unidentate Organic Nitriles

Published: February 2022

A number of adducts of copper(I) cyanide, CuCN, have been synthesized by crystallization from its solutions in various unidentate organic nitriles, RCN. Low temperature single crystal X-ray structure determinations are recorded for a number of these, of the form CuCN : RCN (m : n) for R = Me, Et (m : n = 1 : 1), and Ph, o-tolyl (3:2). The 1 : 1 adduct with acetonitrile is a two-dimensional polymeric web, (CN)Cu(μ-CN)2Cu(NC) units being linked by the peripheral nitrogen and carbon atoms, with a fourth coordination site about each copper having MeCN pendant. The other three adducts are onedimensional polymers, the propionitrile adduct being of the form . . .Cu(NCEt)CNCu(NCEt)CN. . . with trigonal planar copper, the bridging cyanide groups being replaced in the benzo- and o-toluo nitrile adducts by linear Cu(CN)−2 moieties. The vibrational spectra of bulk samples are largely consistent with the single crystal structural results, but reveal the possible existence of adducts of higher CuCN content in the case of the CuCN/benzonitrile system.
Solvothermal Synthesis of [C6H17N3]Sb10S16: A New Thioantimonate(III) with an in-situ Formed Organic Amine Cation
Authors: Kiebach Ragnar , Näther Christian , Bensch Wolfgang
Published: February 2022

The new thioantimonate(III) [C6H17N3][Sb10S16] (C6H17N3 = 2-piperazine-N-ethylamine cation) was obtained under solvothermal conditions showing a unique anionic framework. The compound crystallizes in the monoclinic space group P21/c with four formula units in the unit cell. The lattice parameters are a=11.530(2), b=25.042(5), c = 13.709(3)Å, β =111.25(3)◦,V = 3689(2) Å3. The thioantimonate(III) anion is formed by interconnection of nine trigonal pyramidal SbS3 units and one SbS4 moiety. These primary building units share common corners and edges yielding Sb3S3 and Sb2S2 hetero-rings. Further condensation leads to strong undulated two atoms thick layers extending in the [010] direction, with a modulation period of about 14 Å. Very large Sb31S31 rings within the layers show a ‘double-ellipsoidal’ shape with approximate dimensions of 8.9 ・ 9.3 Å. The cations are located at the inflexion points of the layers and act as pillars between successive layers. The layers are stacked onto each other in a way that channels parallel to [001] are formed accommodating the organic cations. A remarkable observation is that the 2-piperazine-N-ethylamine cation is formed by cyclization of tren molecules (tren = tris(2-aminoethyl)amine) under in-situ conditions.

The reaction of Fc(S2CNEt2)2 (Fc = Fe(η5-C5H4)2) with [Ag(OTf)(PPh3)] (OTf = trifluoromethanesulfonate) or [Au(OClO3)(PPh3)] in various molar ratios gives complexes of stoichiometry [Ag(PPh3){Fc(S2CNEt2)2}]OTf, [Ag(PPh3)2{Fc(S2CNEt2)2}]OTf, [Ag2(PPh3)2{Fc(S2 CNEt2)2}](ClO4)2or [Ag3(PPh3)3{Fc(S2CNEt2)2}](ClO4)3. Treatment of Fc(S2CNEt2)2 with Ag(OTf) gives the complex [Ag(OTf){Fc(S2CNEt2)2}], which can easily react with bidentate ligands such as 1,10-phenanthroline (phen), bis(diphenylthiophosphoryl)methane ((SPPh2)2CH2) or NaS2CNEt2 to afford the cationic complexes [Ag(phen){Fc(S2CNEt2)-}]OTf, [Ag{(SPPh2)2 CH2}{Fc(S2CNEt2)2}]OTf or the neutral [Ag(S2CNEt2){Fc(S2CNEt2)2}]. The crystal structure of [Ag(PPh3)2{Fc(S2CNEt2)2}]OTf reveals that silver coordinates to the dithiocarbamate sulfur atoms of two ferrocene ligands, thus forming a chain polymer.

In this study, spiced turkey slices were dried at different temperatures (60 and 70°C) and microwave powers (0, 180 and 360 W at fixed product weight) and physical, chemical, microbiological and sensory quality characteristics of these dried slices were determined. The turkey slices dried at these conditions had an average moisture content of 25%, an aw value of 0.72, a pH value of 6.02, and a thiobarbituric acid reactive substance (TBARS) value of 15.77 µmol MDA/kg. It was determined that the cutting force value of the samples increased to 56.14 N depending on the temperature increase and to 59.12 N depending on the increase in microwave power. In addition, it was found that the L* value of the samples decreased significantly (p < 0.01) as the microwave power increased. Furthermore, the microbial quality was better in samples applied at 70°C drying temperature and 360 W microwave power.

Abstract. The internal conflict between the Afghan government and the Taliban has been going on for a long time, and in mid-August 2021 the Taliban succeeded in taking over the Afghan government in Kabul. Various countries began to respond to the event, especially countries that have established diplomatic, economic and military cooperation with Afghanistan, including India. This article aims to analyze the potential for bilateral cooperation in the economic and security fields between India and Afghanistan, especially after the Taliban's success in occupying Kabul and announcing the Afghan government under the Taliban. Qualitative research with descriptive analytical methods is applied in this research, based on data sources obtained through literature study techniques. This research shows that India has the potential to take a policy to continue to cooperate with Afghanistan in the economic and security fields. This due to India's national interest in Afghanistan such as controlling Afghanistan's mineral resources and realizing India as a regional power in the South Asian region.

BACKGROUND AND OBJECTIVES

Achievement of independent oral feedings remains the most common barrier to discharge in preterm infants. Early oral feeding initiation may be associated with a lower postmenstrual age (PMA) at independent oral feeding and discharge. In preterm infants born between 25 and 32 weeks’ gestation, our aim was to decrease the PMA at independent oral feedings and discharge by 1 week between June 2019 and June 2020.

METHODS

Following formation of a multidisciplinary team, the following plan-do-study-act cycles were targeted: (1) oral feeding initiation at <33 weeks’ PMA, (2) cue-based feeding, and (3) practitioner-driven feeding in infants who had not yet achieved independent oral feedings by 36 weeks’ PMA. Outcome measures included the PMA at independent oral feeding and discharge. Process measures included adherence to cue-based feeding assessments and PMA at oral feeding initiation.

RESULTS

In total, 552 infants with a median gestational age of 30.3 weeks’ (interquartile range 28.1–32.0) and birth weight of 1320 g (interquartile range 1019–1620) were included. The PMA at discharge decreased from 38.8 to 37.7 weeks during the first plan-do-study-act cycle, which coincided with an increase in the number of infants initiated on oral feeds at <33 weeks’ PMA from 47% to 80%. The age at independent oral feeding decreased from 37.4 to 36.5 weeks’ PMA.

CONCLUSIONS

In preterm infants born between 25 and 32 weeks’ gestation, earlier oral feeding initiation was associated with a decreased PMA at independent oral feeding and discharge.

Aim of the study: Early motherhood is the time when the female body must cope with sleep deprivation, fatigue, and stress associated with increased responsibilities following the birth of the baby. The aim of this paper was to investigate the psychological wellbeing and physical activity of healthy mothers in the first months postpartum according to the infants’ feeding method. Materials and methods: 24 healthy exclusively breastfeeding and 13 healthy exclusively formula-feeding mothers participated in this study. The results were based on the standardised scales: Fatigue Severity Scale (FSS), Epworth Sleepiness Scale (ESS), Perceived Stress Scale (PSS), and Kaiser Physical Activity Survey (KPAS). Results: When comparing data between the two studied groups, we found that breastfeeding women reported lower levels of sleepiness (p = 0.011) and fatigue (p = 0.0006) than formula-feeding mothers. Perceived stress and physical activity did not differ between the groups. Positive correlation between PSS and FSS was found (r = 0.62, p < 0.005) in the group of breastfeeding mothers. Conclusions: 1) In breastfeeding mothers, fatigue and perceived stress reinforce each other. This relationship serves as an alarm signal to provide nursing mothers with optimal care in order to prevent them from stopping breastfeeding. 2) In a healthy population of mothers from 3 to 6 months postpartum, exclusively breastfeeding women are observed to have lower fatigue and sleepiness levels compared to those who decided to feed their children with formula only. These conclusions may be an additional source of information for the promotion of breastfeeding.

Autoimmune encephalitis is rare in children and develops as a manifestation of a parainfectious or paraneoplastic syndrome. The disease is characterised by a sudden or subacute onset and a broad spectrum of neurological and/or psychiatric disorders. We present a case of a 17-year-old girl with anti-N-methyl-D-aspartate receptor encephalitis. The patient was admitted to hospital in a severe condition, unconscious, with injuries indicating a recent status epilepticus. Previous infection was found to be the most likely causative factor. Antiviral, antibacterial, immunosuppressive and anticonvulsant treatments were used with good outcomes. The aim of the paper is to point out the need to include autoimmune processes in the differential diagnosis of neuroinfections in children, which will allow for prompt implementation of appropriate treatment and improve prognosis.

Congenital central hypoventilation syndrome is a very rare genetic disorder. The disease involves respiratory failure associated with impaired central control of the breathing process. Hirschsprung’s disease is the cause of congenital intestinal obstruction as a result of the agenesis of ganglion cells in the submucosal and myenteric plexuses. If congenital central hypoventilation syndrome and Hirschsprung’s disease occur simultaneously, Haddad syndrome is diagnosed. A male infant was born at 37 weeks of gestation in a moderate general condition. Due to increasing respiratory effort and increased demand for oxygen, the newborn was intubated and mechanically ventilated. During an extubation attempt, respiratory symptoms intensified, and CO2 was accumulating on blood gas test. Genetic tests revealed a mutation in the PHOX2B gene, which confirmed congenital central hypoventilation syndrome. Lack of meconium and enteral nutrition intolerance were observed. Hirschsprung’s disease was diagnosed on the basis of intestinal biopsy. Loop ileostomy was created at 5 weeks of life. Due to coexistence of congenital central hypoventilation syndrome and Hirschsprung’s disease, Haddad syndrome was diagnosed.

Soft tissue sarcoma, especially synovial sarcoma, is extremely rare in infancy, with only a few cases reported worldwide. Due to the particularly small size of the head and neck region in infants, with important anatomical structures in close vicinity to one another, surgical resection is very challenging, if the goal is to ensure total disease elimination as well as maintaining function and good cosmetic outcome postoperatively. In the case reported here, following diagnosis, the child was given three cycles of neoadjuvant chemotherapy followed by infratemporal tumour resection via Bramley–Al-Kayat incision incorporated with a modified Blair incision. Postoperatively, the child recovered well, with no recurrence after three months. This case highlights the important role of a multidisciplinary approach in the diagnosis and managing such rare cases. We also discuss the clinical presentation, imaging features, histopathological features, treatment regime, and prognosis of synovial sarcoma of the infratemporal fossa in children, based on cases reported in the literature.

Pfeiffer syndrome is a severe autosomal dominant condition that affects many systems of the human body. It is caused by mutations in the fibroblast growth factor receptors of the fibroblast growth factor genes. The phenotype of patients with Pfeiffer syndrome includes multiple limb and cranial abnormalities, and mental retardation. The infant reported here also had cloverleaf-shaped skull, broad thumbs and big toes, bilateral syndactyly, and hypertelorism. The patient was hospitalised in the Lviv Regional Clinical Hospital with multiple congenital malformations and severe neurological status. Acrocephaly, cloverleaf-shaped skull and severe concomitant neurological complications suggested Pfeiffer syndrome, which was later confirmed.
