Background: The esophageal-tracheal Combitube (ETC) was developed for the management of difficult airways but can also be used for general anaesthesia.
Methods: This clinical study collected data from patients undergoing anaesthesia with the ETC in order to assess the rate of complications.
Results: Five hundred forty patients were ventilated with the ETC. In 94.8% (512/540), insertion was performed for the first time by the respective physician. The following minor complications were observed: 38.7% sore throat, 30.9% blood on tube as sign of mucosal lesions and 17.0% cyanotic tongue. Experience decreased the risk of mucosal lesions (odds ratio [OR]: 2.3, 95% confidence interval [CI]: 1.5–3.5). A higher than recommended volume of the oropharyngeal cuff was associated with blood on the ETC (OR: 1.5, 95% CI: 1.0–2.3) and tongue cyanosis (OR: 2.3, 95% CI: 1.4–3.7). Ventilation for more than 2 h was associated with tongue cyanosis (OR: 2.2, 95% CI: 1.6–3.1) and tongue protrusion (OR: 1.4, 95% CI: 1.1–1.9).
Conclusion: We conclude that the Combitube may be used for short procedures requiring general anaesthesia, but the high rate of minor complications limits its value when other alternatives such as a laryngeal mask airway are available. The tested method appears safe regarding major complications, but minor complications are common. Adherence to recommended cuff volumes, experience with the ETC and limiting its use to surgeries lasting less than 2 h might reduce the rate of complications.

Published: April 2023

Abstract
Importance: Parent–child play is a beneficial and meaningful co-occupation. Therapists who want to optimize parent–child play for Latino- and Latina-American dyads need valid, reliable measures to assess caregiver playfulness in addition to preexisting measures of child playfulness.
Objective: To evaluate data collected from Latino-American caregivers with the Scale of Parental Playfulness Attitude (PaPA), a 28-item parent self-report to determine its construct validity, internal reliability, and cross-cultural validity.
Design: Quantitative exploratory design applying a latent-trait psychometric model.
Setting: Online survey.
Participants: Convenience sample of 50 Spanish-speaking parents from the mainland United States recruited via snowballing (88% mothers, ages 24–47 yr; M = 34.8 yr; 82% first-generation Americans). The inclusion criteria were age ≥18 yr; literate in Spanish; primary caregiver to a child age 2.5–7 yr. Data from an existing sample of 50 parents dwelling in Puerto Rico were used to examine cross-cultural validity.
Outcomes and Measures: Rasch analysis demonstrated evidence for adequate construct validity: positive point-measure correlations, 93% fit of items, logical item hierarchy, and good progression of the rating scale. Range and mean for parent playfulness exceeded those of the items; principal-components analysis revealed one contrast of 4.46 eigenvalues, bringing unidimensionality into question. Evidence suggested excellent internal reliability (person-reliability index = 0.85, strata = 3.55) and good cross-cultural validity (25 of 28 items formed a similar hierarchy for parents dwelling in the mainland United States and Puerto Rico).
Conclusions and Relevance: Although the PaPA can be used to assess caregiver playfulness with culturally diverse Latino-American dyads, further research is required.
What This Article Adds: This study provides evidence for the construct validity and internal reliability of a tool that measures parent playfulness in the context of parent–child play. The PaPA is an important tool for occupational therapists working with Latino-American families.
Social Participation Experiences of Families Raising a Young Child With Autism Spectrum Disorder: Implications for Mental Health and Well-Being
Authors: Smith Julie , Halliwell Nicole , Laurent Amy , Tsotsoros Jessica , Harris Katelyn , DeGrace Beth 
Published: April 2023

Importance: Social participation (SP) is an important facilitator of positive mental health for children and families. Children are dependent on their families to mediate SP, yet families of children with autism spectrum disorder (C-ASD) seemingly limit SP because of behavioral and functional challenges in community environments. The resulting isolation can affect the child’s and the family’s mental health.
Objective: To distill the essence of everyday SP experiences in the community of families raising C-ASD.
Design: Data collected via in-depth, semistructured interviews with a purposive sample and analyzed in the phenomenological tradition.
Setting: Community.
Participants: We recruited seven families with English-speaking parents (ages 18–64 yr) raising one C-ASD (age 2–8 yr). Families with more than one C-ASD or those whose C-ASD was diagnosed with complex medical condition or a neurological or genetic disorder were excluded.
Results: The essence of experiences of SP emerged in the form of three themes depicting the mismatch between societal expectations for SP and families’ experience: (1) “the struggle,” (2) “it’s hard to feel like you belong,” and (3) what we “have to do.”
Conclusions and Relevance: As a collective, families expressed desire for everyday community SP and could do so only in select environments with core groups. The findings, as interpreted through the lens of mental health promotion, reveal opportunities to reduce barriers and to promote meaningful family SP so as to facilitate positive mental health and well-being through the transactional intersecting characteristics of the child with ASD, the family, and the community.
What This Article Adds: This study illuminates the experience of SP of families raising a young C-ASD, highlighting both supports and barriers. Practitioners can use this information to potentially prevent isolation and promote both child and family mental health and well-being.

Abstract. The Peruvian upwelling system is a highly productive ecosystem with a large
oxygen minimum zone (OMZ) close to the surface. In this work, we carried out a
mesocosm experiment off Callao, Peru, with the addition of water masses from
the regional OMZ collected at two different sites simulating two different
upwelling scenarios. Here, we focus on the pelagic remineralization of organic
matter by the extracellular enzyme activity of leucine aminopeptidase (LAP) and
alkaline phosphatase activity (APA). After the addition of the OMZ water,
dissolved inorganic nitrogen (N) was depleted, but the standing stock of
phytoplankton was relatively high, even after N depletion (mostly
> 4 µg chlorophyll a L−1). During the initial phase of
the experiment, APA was 0.6 nmol L−1 h−1 even though the
PO43- concentration was > 0.5 µmol L−1.
Initially, the dissolved organic phosphorus (DOP) decreased, coinciding with
an increase in the PO43- concentration that was probably linked to the APA. The
LAP activity was very high, with most of the measurements in the range of
200–800 nmol L−1 h−1. This enzyme hydrolyzes terminal amino acids
from larger molecules (e.g., peptides or proteins), and these high values are
probably linked to the highly productive but N-limited coastal ecosystem.
Moreover, the experiment took place during a rare coastal El Niño event with
higher than normal surface temperatures, which could have affected enzyme
activity. Using a nonparametric multidimensional scaling analysis (NMDS)
with a generalized additive model (GAM), we found that biogeochemical
variables (e.g., nutrient and chlorophyll-a concentrations) and phytoplankton and
bacterial communities explained up to 64 % of the variability in APA. The
bacterial community best explained the variability (34 %) in LAP. The high
hydrolysis rates for this enzyme suggest that pelagic N remineralization,
likely driven by the bacterial community, supported the high standing stock
of primary producers in the mesocosms after N depletion.

Published: April 2023

Abstract. We have created a performance-based assessment of CMIP6 models for Europe that can be used to inform the sub-selection of models for this region. Our assessment covers criteria indicative of the ability of individual models to capture a range of large-scale processes that are important for the representation of present-day European climate. We use this study to provide examples of how this performance-based assessment may be applied to a multi-model ensemble of CMIP6 models to (a) filter the ensemble for performance against these climatological and processed-based criteria and (b) create a smaller subset of models based on performance that also maintains model diversity and the filtered projection range as far as possible. Filtering by excluding the least-realistic models leads to higher-sensitivity models remaining in the ensemble as an emergent consequence of the assessment. This results in both the 25th percentile and the median of the projected temperature range being shifted towards greater warming for the filtered set of models. We also weight the unfiltered ensemble against global trends. In contrast, this shifts the distribution towards less warming. This highlights a tension for regional model selection in terms of selection based on regional climate processes versus the global mean warming trend.

Published: April 2023

ABSTRACT
Terminal phospholipid groups contribute considerably to the excellent comprehensive properties of NR, but their aggregation behaviors and influence on polyisoprene properties during storage and use have not yet been revealed at the molecular level. To begin to address these phenomena, two sequentially different polyisoprene copolymers were suspended with phosphorylcholine groups to disclose their influence on phase separation, network dynamics, mechanical properties, and crystallization differences. Phosphorylcholine groups attached to polymer chains can form aggregates that increase the storage modulus of rubbers, and this process is accelerated at elevated temperatures due to faster chain movement. In addition, phosphorylcholine groups act as crosslinking points in unvulcanized and vulcanized rubbers and increase mechanical properties by promoting strain-induced crystallization (SIC). By contrast, the polymers with pendant hydroxyl groups present sequence-dependent SIC properties that are ascribed to their non-aggregation nature.
Poe’s Last Jest: The Magazine Prison-House, Colonial Exploitation, and Revenge in “Hop-Frog”
Authors: Gruesser John 
Published: April 2023

Abstract
This article looks at Edgar Allan Poe’s “Hop-Frog” in connection with revenge, one of the oldest and richest themes in literature. As the author has done in connection with “The Cask of Amontillado,” this article offers a generalized biographical interpretation of this 1849 story, linking it to Poe’s February 1845 essay “Some Secrets of the Magazine Prison-House” with its emphasis on “fat,” exploitive “editors and proprietors,” as well as his September 1845 “Marginalia” piece about the sorry state of the American publishing industry. Contending that the story must be read vis-à-vis not only enslavement and slave rebellion, as several critics have done, but also colonization, this article casts doubt on claims that Poe used the tale to settle scores with personal enemies or to revenge himself on the reading public. A brief coda argues that in “Hop-Frog” Poe does not simply avenge himself on those responsible both for his own exploitation as “a poor devil author” and the colonization of American literature generally. Rather, he counterbalances the gruesome, fiery climax with a celebratory compendium of many of his greatest hits through allusions to at least eleven of his writings published between 1835 and 1846.
Meditation, Personality, and Workplace Stress
Authors: Waters Andrew , Shanock Linda 
Published: April 2023

The prevalence of stress occurs across various levels of the workplace can affect employees at any level of an organization. This study explored the role of meditation frequency on stress reduction in the workplace. Previous research emphasizes the role of personality traits in perceiving stressful situations (Childs et al., 2014), and this study investigated if conscientiousness and neuroticism personality traits helped to limit or enhance stress reduction. A sample of 40 participants was given the choice of both how frequently they choose to meditate and what style of meditation they chose to practice over two weeks. Results showed that meditation frequency had a significant impact on stress reduction. Additionally, the role of personality traits did not provide a significant impact on the participant's perceptual change in stress. The findings suggest that the frequency of meditation practice matters, and, in practical terms, future organizational policies may promote employee choice on meditation frequency and style.
Leadership Alignment

Published: April 2023

Many school administrators struggle to find a reliably efficient and effective way of stabilizing academic reform implementation within educational institutions. Questionnaire responses were collected from two administrators and six teachers across two schools in the same school district, with the intent of examining if teachers’ and administrators’ perceptions of administrative leadership align within the same school. The findings of this research study conclude that educational leadership can be effectively implemented through the shared vision of the school, communication, collaboration, and supportive resources, along with humane characteristics utilized throughout those categories to create rapport and positive school culture. This study contributes to the greater understanding between the academic structures of top-down leadership and transformational leadership. Limitations include the small sample size, short time frame of the study, and only middle school representation. The concluding message is that by distributing responsibilities, schools have a greater change to cultivate academic and social change.

Mucoraceae are ubiquitous fungi and are found in, soil, air, contaminated water and hospital environments too. These fungi usually gain entry into host through respiratory tract and sinuses either by direct spread or by angioinvasion. Major sites of infection are sinuses, lungs, skin, brain, and gastrointestinal tract. From sinus it may invade maxilla causing osteomyelitis of jaw. Mucormycosis is an opportunistic infection and the major risk factors include poorly controlled diabetes mellitus (DM), iron overload, prolonged corticosteroid use and immunocompromised status. CORONA virus disease 2019 (Covid-19) is an infection caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The majority of patients have a good prognosis, but some patients become critically ill and even deaths occur. Disease itself decreases cell mediated immunity and increases iron load in covid patients. For treatment of Covid-19 corticosteroids, antiviral drugs and immunomodulatory drugs are being used. Steroid reduces inflammation in covid 19 patients, but it pushes up the blood sugar which causes ketoacidosis, increases iron load, affects cell mediated immunity and favours the mucor mycosis growth. So, there are reported increasing cases of mucormycosis in post COVID-19 patients. Present study includes 25 reported cases of mucormycosis with jaw osteomyelitis in post covid patients with respect to clinical characteristics, past medical history, comorbidities medication received during covid 19, radiographic feature, lab diagnostic methods, histopathological reports, and treatment. So as to gain an insight of this disease as early diagnosis of mucor mycosis and treatment which can significantly reduce the mortality and morbidity of mucormycosis patients

A systematic monitoring of the hydrosphere is important and necessary to maintain a good ecological status of Lake Baikal. The article presents the results of a five-year monitoring of the groundwater and surface waters quality in Listvyanka settlement. The goal is to determine the contamination level of drinking water supply system. In the field studies, portable measurement devices were used for monitoring temperature, pH, Eh, electrical water conductivity and water levels in wells, and water samples were taken for a complete chemical analysis. The analysis of the macrocomponent composition of water was carried out by various methods (flame photometry, volumetric titration, weight method, colorimetry) at the Center for Geodynamics and Geochronology of the Institute of the Earth’s Crust SB RAS (Irkutsk); the trace element composition was determined by the ICP MS method on the Element-2 device (Finnigan MAT, Germany) at the Institute of Geochemistry SB RAS (Irkutsk); microbiological analysis of water samples was performed at the Irkutsk Interregional Veterinary Laboratory; the analysis of isotope characteristics (δ 18O and δD) of water samples was performed in the Laboratory of Hydrogeology of the Institute of the Earth’s Crust SB RAS (Irkutsk) on a Picarro L2140-i gas analyzer.The results obtained indicate a change in macrocomponent composition of waters and an uneven distribution of pollutants over the area. The content of 42 trace elements in groundwater and river waters generally does not exceed the regulatory requirements for drinking water; the exceptions are Fe and Mn. Ten wells do not meet the sanitary and epidemiological rules and norms SanPiN 2.1.4.1074-01. The main sources of groundwater pollution are leaking septic tanks of numerous hotel complexes located in the valleys and on the valley slopes. The processes of water pollution and restoration of natural regime of water are of different intensity. For groundwater and river waters, there were determined the relative concentrations of stable isotopes of hydrogen and oxygen (δD and δ18О), and δD=5.5307·δ18 O–31.815 relationship and the deuterium excess values were obtained. Characteristics δD and δ18 O are the bases of the isotope database for the aquatic environment of Listvyanka settlement.
Testing and Evaluating Typing Ability in Research Writing
Authors: Asha Bavarava  
Published: April 2023

Before a person can generate writing that can be deemed respectable when using a keyboard, it is usually acknowledged that they must first have exceptional typing talents. This is because learning to type requires much practice. This is an essential requirement in order to operate a computer keyboard. In this lesson, you will learn how to design a standardized copy-typing task, complete with instructions on how to build, execute, and use the job to evaluate a person's level of expertise in typing. This lesson aims to teach you how to design a standardized copy-typing task so that you can evaluate a person's level of expertise in typing. This lesson will show you how to build a task that can be used to determine a person's degree of experience in typing. This lesson aims to teach you how to design a problem. This is done so that we can analyze and determine the individual's skill level with typing, which is why it is done. This is done as follows: An inquiry into the dependability of the instrument may be carried out by doing an analysis that consists of both an initial test and a subsequent test at some point in time.
Even though the task has been validated across eleven different languages and the keyboard layouts are specific to each of those languages, we will use a corpus of Dutch copy tasks with a total of 1682 occurrences. This is because we are going to use a Dutch keyboard layout. This is because we will get a Dutch copy job done on the document. According to the findings of several studies, no link can be characterized as being linear between copying speed and age. Nevertheless, this is something that is the case. A Bayesian investigation concluded that there are variations in typing speed and the underlying inter-key interval distributions that occur across the activity's different facets (e.g., lexical vs. non-lexical materials; high-frequent vs. low-frequent bigrams).
The findings here support the argument that writing research should add copy-task metrics to analyzing data received from keyboard recording. This proposal was presented here. This makes it possible to more accurately compare and analyze the keystroke data of persons engaged in writing tasks that are more difficult or communicatively integrated. In the study of writing, there are several other potential applications for the copy assignment; this article delves into each of those potential applications in detail and discusses them.
