Authors: Alghamdi Waleed Ahmed , Alzahrani Sami Hamdan
Published: June 2022

Objective:

This study aimed to investigate the relationship between the different demographic variables and other social, and health-related factors, and the coping styles used by the general population in Saudi Arabia during the COVID-19 pandemic.

Methods:

A cross-sectional study involving 5,514 participants was conducted online over two weeks. An online questionnaire was distributed among attendees of a public awareness campaign. The questionnaire consisted of two sections: (1) sociodemographic variables and questions exploring the physical and mental health of the participants, along with COVID-19 related questions, and (2) the Brief COPE questionnaire to identify the coping styles used by participants.

Results:

The most frequently used adaptive styles involved religion, acceptance, and positive reframing. As for the maladaptive styles, self-distraction, venting, and self-blame were the most frequently used. Comparing the means of coping styles, participants older than 60 and female participants more frequently used religion, acceptance, positive reframing, and active coping, while participants younger than 35 and male participants reported more frequent use of instrumental support and humor. Younger participants used all maladaptive coping styles more frequently than older participants; male and female participants appeared to use different maladaptive coping styles. People with mental health conditions showed less frequent use of adaptive coping styles and more frequent use of maladaptive coping styles.

Conclusion:

The findings of this study show that multiple sociodemographic and health variables such as age, gender, and the presence of mental health conditions may influence the type of coping styles people use during a crisis. These findings could offer a better understanding of how the general public is coping with this unique situation. This may help mental health care workers and public health officials provide appropriate support at both individual and general population levels during this pandemic.

Se realizó un inventario florístico de las plantas arvenses asociadas al cultivo de maíz de temporal durante el ciclo agrícola 1993, en 20 parcelas distribuidas a lo largo de un gradiente altitudinal de 1840 a 2560 m s.n.m., en el Valle de Morelia, Michoacán. En todos los sitios se censaron 10 unidades de muestreo que cubren una área de 2.5 m2 de cada una de las parcelas. El total de muestreos fue de 200. El trabajo de identificación se realizó con base en una colección de 3000 ejemplares. Se identificaron en total 189 especies, pertenecientes a 114 géneros y 34 familias de angiospermas. De ellas 41 son monocotiledóneas y 148 dicotiledóneas. Entre estas últimas destacan Compositae (20.10%) y entre las primeras Gramineae (14.81%). Estas dos familias comprenden el 34.91% del total y junto con Leguminosae, Euphorbiaceae y Solanaceae, representan 52.85% de la riqueza encontrada. La comparación con otras áreas muestra que la flora arvense del Valle de Morelia es significativamente diversa. 11.1% de las especies son introducidas, principalmente del Viejo Mundo, el resto corresponde a plantas nativas de América, destacando las autóctonas de México y áreas circunvecinas. Sesenta y tres especies, aunque citadas de México como nativas, se registran por primera vez como arvenses asociadas a maíz y casi la mitad de ellas restringen su distribución conocida al territorio del país.

Authors: Mohd Hisham Muhammad Faiz , Ahmad Fazila Haryati , Mohamed Haris Hasmah , Lodz Noor Aliza , Yoep Norzawati , Muhammad Eida Nurhadzira , Ali Rafidah , Muhamad Nor Asiah
Published: June 2022

Background

Soil-transmitted helminth (STH) infection is 1 of the 20 notable neglected tropical diseases according to the Centers for Disease Control and Prevention and World Health Organization. In 2010, it is estimated that 1.73 billion people are infected with STH globally, of which 70% of cases occur in Asia. To date, there is a dearth of published literature on the prevalence of STH infection throughout Malaysia.

Objective

The objectives of this study are to review research activity on STH infection in Malaysia, to estimate the prevalence of STH infection among Malaysians, and to identify significant risk factors associated with the infection. This review aims to provide the current state of evidence pertaining to STH infections, focusing on the main areas, limitations, and biases of research and mapping out the morbidity distribution of the diseases and their causative agents, and to identify significant risk factors for preventive measures.

Methods

We will conduct a scoping review based on the 6-stage structured framework developed by Arksey and O’Malley. A comprehensive search strategy focusing on STH infection will be executed using electronic databases (Scopus, PubMed, Web of Science, and Embase). A systematic approach for searching, screening, reviewing, and data extraction will be applied based on the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. Mendeley software and Microsoft Excel will be used to manage the references and to remove duplicates. Relevant data from selected articles will be extracted using a standardized data extraction form.

Results

A total of 164 potential manuscripts were retrieved. Data extraction is currently in progress and completion is expected by the end of 2022.

Conclusions

Our scoping review will summarize the current state of research in this field and provide comprehensive information regarding STH infections in Malaysia for future reference.

Excess Google Searches for Child Abuse and Intimate Partner Violence During the COVID-19 Pandemic: Infoveillance Approach
Authors: Riddell Corinne A , Neumann Krista , Santaularia N Jeanie , Farkas Kriszta , Ahern Jennifer , Mason Susan M
Published: June 2022

Background

The COVID-19 pandemic has created environments with increased risk factors for household violence, such as unemployment and financial uncertainty. At the same time, it led to the introduction of policies to mitigate financial uncertainty. Further, it hindered traditional measurements of household violence.

Objective

Using an infoveillance approach, our goal was to determine if there were excess Google searches related to exposure to child abuse, intimate partner violence (IPV), and child-witnessed IPV during the COVID-19 pandemic and if any excesses are temporally related to shelter-in-place and economic policies.

Methods

Data on relative search volume for each violence measure was extracted using the Google Health Trends application programming interface for each week from 2017 to 2020 for the United States. Using linear regression with restricted cubic splines, we analyzed data from 2017 to 2019 to characterize the seasonal variation shared across prepandemic years. Parameters from prepandemic years were used to predict the expected number of Google searches and 95% prediction intervals (PI) for each week in 2020. Weeks with searches above the upper bound of the PI are in excess of the model’s prediction.

Results

Relative search volume for exposure to child abuse was greater than expected in 2020, with 19% (10/52) of the weeks falling above the upper bound of the PI. These excesses in searches began a month after the Pandemic Unemployment Compensation program ended. Relative search volume was also heightened in 2020 for child-witnessed IPV, with 33% (17/52) of the weeks falling above the upper bound of the PI. This increase occurred after the introduction of shelter-in-place policies.

Conclusions

Social and financial disruptions, which are common consequences of major disasters such as the COVID-19 pandemic, may increase risks for child abuse and child-witnessed IPV.
The AI Will See You Now: Feasibility and Acceptability of a Conversational AI Medical Interviewing System
Authors: Hong Grace , Smith Margaret , Lin Steven
Published: June 2022

Background

Primary care physicians (PCPs) are often limited in their ability to collect detailed medical histories from patients, which can lead to errors or delays in diagnosis. Recent advances in artificial intelligence (AI) show promise in augmenting current human-driven methods of collecting personal and family histories; however, such tools are largely unproven.

Objective

The main aim of this pilot study was to evaluate the feasibility and acceptability of a conversational AI medical interviewing system among patients.

Methods

The study was conducted among adult patients empaneled at a family medicine clinic within a large academic medical center in Northern California. Participants were asked to test an AI medical interviewing system, which uses a conversational avatar and chatbot to capture medical histories and identify patients with risk factors. After completing an interview with the AI system, participants completed a web-based survey inquiring about the performance of the system, the ease of using the system, and attitudes toward the system. Responses on a 7-point Likert scale were collected and evaluated using descriptive statistics.

Results

A total of 20 patients with a mean age of 50 years completed an interview with the AI system, including 12 females (60%) and 8 males (40%); 11 were White (55%), 8 were Asian (40%), and 1 was Black (5%), and 19 had at least a bachelor’s degree (95%). Most participants agreed that using the system to collect histories could help their PCPs have a better understanding of their health (16/20, 80%) and help them stay healthy through identification of their health risks (14/20, 70%). Those who reported that the system was clear and understandable, and that they were able to learn it quickly, tended to be younger; those who reported that the tool could motivate them to share more comprehensive histories with their PCPs tended to be older.

Conclusions

In this feasibility and acceptability pilot of a conversational AI medical interviewing system, the majority of patients believed that it could help clinicians better understand their health and identify health risks; however, patients were split on the effort required to use the system, and whether AI should be used for medical interviewing. Our findings suggest areas for further research, such as understanding the user interface factors that influence ease of use and adoption, and the reasons behind patients’ attitudes toward AI-assisted history-taking.
Clinical Targets and Attitudes Toward Implementing Digital Health Tools for Remote Measurement in Treatment for Depression: Focus Groups With Patients and Clinicians
Authors: de Angel Valeria , Lewis Serena , White Katie M , Matcham Faith , Hotopf Matthew
Published: June 2022

Background

Remote measurement technologies, such as smartphones and wearable devices, can improve treatment outcomes for depression through enhanced illness characterization and monitoring. However, little is known about digital outcomes that are clinically meaningful to patients and clinicians. Moreover, if these technologies are to be successfully implemented within treatment, stakeholders’ views on the barriers to and facilitators of their implementation in treatment must be considered.

Objective

This study aims to identify clinically meaningful targets for digital health research in depression and explore attitudes toward their implementation in psychological services.

Methods

A grounded theory approach was used on qualitative data from 3 focus groups of patients with a current diagnosis of depression and clinicians with >6 months of experience with delivering psychotherapy (N=22).

Results

Emerging themes on clinical targets fell into the following two main categories: promoters and markers of change. The former are behaviors that participants engage in to promote mental health, and the latter signal a change in mood. These themes were further subdivided into external changes (changes in behavior) or internal changes (changes in thoughts or feelings) and mapped with potential digital sensors. The following six implementation acceptability themes emerged: technology-related factors, information and data management, emotional support, cognitive support, increased self-awareness, and clinical utility.

Conclusions

The promoters versus markers of change differentiation have implications for a causal model of digital phenotyping in depression, which this paper presents. Internal versus external subdivisions are helpful in determining which factors are more susceptible to being measured by using active versus passive methods. The implications for implementation within psychotherapy are discussed with regard to treatment effectiveness, service provision, and patient and clinician experience.

UNSTRUCTURED

Waterpipe tobacco smoking (WTS) is a traditional tobacco use method that originated in the Eastern Mediterranean Region (EMR) and has resurged in recent decades. WTS rates in the EMR are the highest worldwide, especially among youth, exceeding cigarette-smoking rates in select jurisdictions. Despite its documented harm, the growing prevalence of WTS has been met with a poor regulatory response globally. At the epicenter of the WTS epidemic, countries in the EMR are in urgent need of effective tobacco control strategies that consider the particularities of WTS. A roundtable session, titled “Monitoring and Combating WTS Through Taxation and the Global Tobacco Surveillance System (GTSS),” was held as part of the 7th Eastern Mediterranean Public Health Network’s regional conference. The session provided an overview of evidence to date about WTS policy control, the taxation of WTS, volumetric choice experiments for tobacco control research, and monitoring WTS patterns and control policies among adults and youth through the GTSS. The session highlighted the need to update the regulation of WTS in the current global tobacco control policy frameworks and the need for developing tailored, evidence-based, and WTS-specific regulations to complement current tobacco control policy frameworks. Raising taxes to increase the price of tobacco products is the single most effective tobacco control measure, and these taxes can fund expanded government health programs. The effectiveness of taxation can be measured via volumetric choice experiments, which allow for the estimation of a complete set of own-price and cross-price elasticities that are instrumental for fiscal policy simulations. Finally, the surveillance of WTS (for example, through the GTSS) is critical to informing policy and decision makers. The Global Youth Tobacco Survey (GYTS) and Global Adult Tobacco Survey (GATS) are 2 GTSS products that provide nationally representative data among students aged 13-15 years and persons ≥15 years, respectively.

Published: June 2022

Team-teaching is a prominent approach used widely in the world especially in interdisciplinary and ESP (English for Special Purpose) teaching to enhance the quality of teaching and learning and foster teachers’ professional development. However, for many Vietnamese teachers, it remains unexplored territory because it is not fully employed in education system of Vietnam. The aim of this study was to explore the team-teaching teachers’ viewpoints and attitudes towards team-teaching as a tool for professional development through an interpretation of qualitative data derived from classroom observations and post-observation in-depth interviews with 5 participants in a People’s Police University setting. The findings of the study revealed that most participants claimed to have benefited from team-teaching as a tool to improve their professional development. They, however, also had to face some drawbacks arising from this approach. Some recommendations for the administrators and team-teachers were given in the hope of fostering the benefits and reducing the difficulties of team-teaching.
Under beredskap och krig. Nation, kön, främlingskap och våld hos svenska kvinnliga 1940-talsförfattare
Authors: Järvstad Kristin
Published: June 2022

Military preparedness and war have so far been regarded as the domain of male authors in Swedish literature, especially at the time of the Second World War. But what happens if we turn our attention to the female authors of the 1940s? Kristin Järvstad’s study shows how their texts as well focus to a large extent on subjects related to military preparedness and war. A variety of topics can be found in the novels by the female writers, ranging from stories about female air guards who protect the Swedish border to female pacifists who find it necessary to kill for the sake of peace. The soldier figure in these texts also takes a radical stand when he as a deserter lays down his arms to protest against the war. In addition, one of the most charged subjects of the time linked to gender is treated from a unique perspective: the women who consort with the occupying enemy are pictured without the condemning attitude that characterizes the period in general. The most urgent question, however, concerns alienation, linked to race: who is actually included in the Swedish nation? Here, the texts display a scathing critique of the narrow-minded Swedes and the anti-Semitism that flourishes at that time. By analysing female authors’ depictions of the 1940s, During Military Preparedness and War deepens the previous picture of this period in Swedish literature. The writers explored in this investigation express a profound and often critical commitment to the issue of war and violence, linked to gender and alienation. The most radical literary message of the period can also be found among their novels: the demand for the dissolution of the militaristic and patriarchal nation which strives to expand its territory without regard for human life.

Amphetamines Exacerbate then Ameliorate Respiratory Effects of Fentanyl as Their Dose Increases
Authors: BA Harrison J. Elder, , PhD Neil B. Varshneya, , PhD D. Matthew Walentiny, , PhD Patrick M. Beardsley,
Published: June 2022

Background and Purpose: The opioid epidemic remains one of the most
pressing public health crises facing the United States. Rising rates of
opioid-involved overdose deaths are presently driven primarily by
fentanyl and related synthetic opioid agonists that are resistant to
reversal by naloxone and increasingly used as adulterants or clandestine
substitutes in illicitly produced opioids, sedatives, and
psychostimulants. Deaths involving opioids typically result from lethal
respiratory depression and it is currently unknown whether co-use of
psychostimulants with opioids affects respiratory toxicity. Considering
psychostimulant overdoses have increased over 3-fold since 2013, and
half of those co-involved opioids, this is a cardinal question.
Experimental Approach: Naloxone, d-amphetamine (AMPH), and
(+/-)-methamphetamine (METH), were evaluated for their effects on basal
and fentanyl-depressed respiration. Minute volume (MVb) was measured in
awake, freely moving mice via whole-body plethysmography to quantify
fentanyl-induced respiratory depression and its modulation by dose
ranges of each test drug. Key Results: Naloxone reversed respiratory
depression induced by fentanyl only at the highest dose tested (10
mg•kg-1). Both AMPH and METH exhibited bidirectional effects on MVb
under basal conditions, producing depressions then elevations of
respiration as dose increased. Under depressed conditions the
bidirectional effects of AMPH and METH on respiration were exaggerated,
exacerbating and then reversing fentanyl-induced depression as dose
increased. Conclusions and Implications: These results indicate that
co-use of amphetamines with fentanyl may worsen respiratory depression,
but conversely, monoaminergic components of the amphetamines may
possibly be exploited to mitigate fentanyl overdose.
“Hydrogen storage in SiC, GeC, and SnC nanocones functionalized with Nickel , DFT – Study”
Authors: Taha H. , elmahdy atef , Shemy Fatma El , Hassan Mohammed
Published: June 2022

Hydrogen is regarded as one of the most potential sustainable energy
sources in the future. applications including transportation. Still, the
event of materials for its storage is difficult notably as a fuel in
vehicular transport. Nanocones are a promising hydrogen storage
material. Silicon, germanium, and tin carbide nanocones have recently
been proposed as promising hydrogen storage materials. In the present
study, we have investigated the hydrogen storage capacity of iC,GeC and
SnC nanocones functionalized with Ni. The functionalized Ni a are found
to be adsorbed on iCNC,GeCNC and SnCNC with an adsorption energy of
-5.56, -6.70 and -4.25 eV. The functionalized iCNC,GeCNC and SnCNC bind
up to seven, six and four molecules of hydrogen with the adsorption
energy of (-0.34, -0.35 and -0.26 eV) and an average desorption
temperature of around 434, 447 and 332K (ideal for fuel cell
applications). The SiC, GeC, and SnC nanocones systems exhibit a maximum
gravimetric storage capacity of 12.51, 7.78 and 4.08 wt%. We suggested
that Ni- SiCNC and Ni- GeCNC systems can act as potential H2 storage
device materials because of their higher H2 uptake capacity as well as
there with strong interaction adsorbed hydrogen molecules than Ni- SnCNC
systems. The hydrogen storage reactions are characterized in terms of
the charge transfer, the partial density of states (PDOS), frontier
orbital band gaps, isosurface plots, and electrophilicity are calculated
for the functionalized and hydrogenated SiC,GeC and SnC nanocones.

INTELLIGENT PREDICTION OF LOAD-DEPENDENT POWER LOSS IN A WIND TURBINE GEARBOX: APPLICATION TO 3. 0 MW WIND TURBINES
Authors: David AFUNGCHUI , Emmanuel CHI , Hermann Djeudjo , Joseph Ebobenow
Published: June 2022

This paper presents the load-dependent power loss in a wind turbine
gearbox under real-time operating wind speed for three different oil
formulations. The gear power loss was determined using mathematical
models from the values of gear loss factors and specific film thickness
experimentally determined by other researchers. The bearing power loss
was determined using the new SKF calibrated model. Wind data from
Bafoussam, a town in Cameroon was used to validate the model. A back
propagation neural network with different numbers of hidden neurons was
designed for power loss modeling and prediction. The achieved results
reveal that the load-dependent power loss in a wind turbine gearbox is
greatly influenced by wind speed and oil type. Finally, it is shown that
the predictive performance of the neural network is also influenced by
the number of neurons in the hidden layer.
Where can distinguishing features be extracted in an image for visibility estimate?
Authors: wang han , Liu Jia Li , Shen Ke Cheng , Shi Quan
Published: June 2022

Standard convolution is difficult to provide an effective fog feature
for visibility estimate tasks due to the fixed grid kernel structure. In
this paper, a multiscale deformable convolution model (MDCM) is proposed
to extract features that make effectively sampling discriminating
features from the atmospheric region in foggy image. Moreover, to
enhance performance we use RGB-IR image pair as observations and design
a multimodal visibility range classification network based on the MDCM.
Experimental results show that both the robustness and accuracy of
visibility estimate performance are raised beyond 30% compared to
standard convolutional neural networks (CNNs).
Method of Electroomic Conversion of Energy Using Electric Currents with Turbulent Character
Authors: Ashcheulov Anatoly , Derevianchuk Mykola , Lavreniuk Dmytro
Published: June 2022

During the twentieth century, scientific and technological progress has
led to a sharp increase in energy consumption. Since the beginning of
the XXI century, hydrocarbon raw materials have become the basis of
energy generation. Scientists around the world are currently working on
the development and implementation of new alternative methods of energy
generation. The share of ecological generation is growing every year,
but such growth does not keep up with the increase in consumption. With
this in mind, the article conducted a study proposing a new approach to
electricity generation. The operation of the proposed devices is based
on the conversion of electric current by an anisotropic electrically
conductive medium characterized by different p- and n-types of
conductivity in selected crystallographic directions under ohmic
contact. It is shown that in the case of an external sinusoidal electric
current flowing through a device based on an anisotropic rectangular
plate, vortices of electric current occur in its volume. Such electric
vortices with turbulent flow are an effective mechanism that pumps
energy between the environment and in our case, the anisotropic plate.

Published: June 2022

Redo cardiac surgery can present a unique set of challenges even to the
experienced surgeon. Although outcomes have steadily improved in the
modern era; if an intraoperative adverse event occurs, there is a 5%
incidence of mortality and 19% incidence of myocardial infarction,
stroke or death [(1)](#ref-0001). Overall, the modern incidence of
mortality at reoperation varies but be segregated into low and higher
risk cohorts depending on the planning computed tomography imaging and
risk to substernal structures on re-entry [(2, 3)](#ref-0002).
Patients with ascending aortic or root pseudoaneurysms represent a
particularly difficult subset of high-risk patients requiring
re-operative cardiac surgery due to the danger of exsanguination and air
embolization [(4)](#ref-0004). Some surgeons advocate the use of
deep hypothermic circulatory arrest (DHCA) to achieve safe re-entry in
such cases however this can result in unpredictable DHCA duration
depending on the degree of pericardial adhesions [(5)](#ref-0005).
We report a case of aortic pseudoaneurysm in a patient with patent
coronary grafts managed using an endoballoon precisely positioned
relative to the proximal anastomoses resulting in a safe surgical
re-entry and shorter DHCA time.
Crop rotation combined with controlled-release fertilizer promoted the utinization of the reclaimed land along Yanze River through improving soil fertility and nutrients use efficiency
Authors: Xu Xuebin , Ma Fei , Zhou Jianmin , Du Changwen
Published: June 2022

Although fertilization of controlled-release fertilizer (CRF) and crop
rotation have been shown the contribution to improving yield, nutrient
use efficiency, and soil fertility, their interactions on the quality of
relcalimed land remains unclear. Hence, a field experiment was conducted
in a reclaimed land along Yangze River to investigate their
interactions. Results indicated that application of bulk blending urea
(BBU) of conventional urea and controlled-release urea (CRU) with
appropriate dosage and frequency increased the rice yield and nitrogen
agronomic efficiency (NAE). Crop rotation also improved the rice yield
and NAE through enhancing the retention capability of fertility. Crop
rotation combined with fertilization significantly increased the soil
pH, organic carbon (SOC), total N (TN), and permanganate oxidizes carbon
(POXC). The rice-green manure (RG) rotation improved soil pH and TN
most, and the rice-rape (RR) rotation improved SOC most. Fertilization
of conventional urea and BBU both significantly increased the labile SOC
functional groups and reduced the the stabled SOC functional groups
under RG rotation. Under RR rotation, however, only fertilization of
conventional urea increased the labile SOC functional groups and reduced
the the stabled SOC functional groups. The rice-wheat (RW) rotation
showed no significant effects on the changes in soil organic functional
groups. The changes in soil properties had significant effects on
improving rice yield or NAE under RG and RR rotations instead of RW

“Throw it in as a Covariate?” Common Problems Using Measured Control Variables in Experimental Research
Authors: Piercey M. David
Published: June 2022

This paper discusses common pitfalls in the use of covariates in experimental accounting and auditing research. Sometimes these mistakes are uncovered in the review process, giving authors more problems to wade through (including a little credibility loss with reviewers) in an already-difficult review process. Sometimes these mistakes are not uncovered in the review process, leading to analyses that support dubious inferences in the published literature. Sometimes these mistakes are even introduced into papers by reviewer comments. Two objectives of this paper are (1) to help authors and coauthors (including early-career researchers) prevent some common, unforced errors from making their way into their research, and (2) to give authors, reviewers, and editors a reference for explaining within the review process why a covariate should be modeled in a certain way, without having to begin the discussion of these ideas from scratch.

OBJECTIVE

To examine whether the effect of a 3-year lifestyle intervention on body weight and cardiometabolic risk factors differs by prediabetes metabolic phenotype.

RESEARCH DESIGN AND METHODS

This post hoc analysis of the multicenter, randomized trial, PREVention of diabetes through lifestyle interventions and population studies In Europe and around the World (PREVIEW), included 1,510 participants with prediabetes (BMI ≥25 kg ⋅ m−2; defined using oral glucose tolerance tests). Of these, 58% had isolated impaired fasting glucose (iIFG), 6% had isolated impaired glucose tolerance (iIGT), and 36% had IFG+IGT; 73% had normal hemoglobin A1c (HbA1c; <39 mmol ⋅ mol−1) and 25% had intermediate HbA1c (39–47 mmol ⋅ mol−1). Participants underwent an 8-week diet-induced rapid weight loss, followed by a 148-week lifestyle-based weight maintenance intervention. Linear mixed models adjusted for intervention arm and other confounders were used.

RESULTS

In the available-case and complete-case analyses, participants with IFG+IGT had greater sustained weight loss after lifestyle intervention (adjusted mean at 156 weeks −3.5% [95% CI, −4.7%, −2.3%]) than those with iIFG (mean −2.5% [−3.6%, −1.3%]) relative to baseline (P = 0.011). Participants with IFG+IGT and iIFG had similar cardiometabolic benefits from the lifestyle intervention. The differences in cardiometabolic benefits between those with iIGT and IFG+IGT were minor or inconsistent in different analyses. Participants with normal versus intermediate HbA1c had similar weight loss over 3 years and minor differences in cardiometabolic benefits during weight loss, whereas those with normal HbA1c had greater improvements in fasting glucose, 2-h glucose (adjusted between-group difference at 156 weeks −0.54 mmol ⋅ L−1 [95% CI −0.70, −0.39], P < 0.001), and triglycerides (difference −0.07 mmol ⋅ L−1 [−0.11, −0.03], P < 0.001) during the lifestyle intervention.

CONCLUSIONS

Individuals with iIFG and IFG+IGT had similar improvements in cardiometabolic health from a lifestyle intervention. Those with normal HbA1c had greater improvements than those with intermediate HbA1c.
The breeding ecology and habitat utilization of some freshwater marsh passerines
Authors:   , Thomas Derek K.
Published: June 2022

The breeding biology of the Reed Warbler Acrocephalus scirpaceus and the Reed Bunting Emberisa schoeniclus was studied at Oxwich Marsh, Gower, primarily during the summers of 1978 and 1879. Three marshland habitat types were identified, and the utilisation, feeding ecology and breeding success of both species in respect of these habitats was considered. In 'pure reed marshes' both species bred earlier, produced heavier young, were predated less and had higher nesting success (i.e. probability of a nest producing young) than those breeding in 'mixed marshes' and other areas. Invertebrates were collected in each habitat. Diptera accounted for a very high proportion of all potential prey items throughout the breeding season. Pure reed marshes produced more invertebrates than elsewhere, and overall peak abundance measured by numbers and biomass ocurred from mid-June to mid-July, coinciding with the time when most young of both species were in the nest. The diet of nestlings based on faecal analysis and hide observations showed Reed Warblers to be generalist feeders, with a similar diet in all habitats. Reed Buntings proved to be more specialist feeders, with a diet varying considerably between habitat types. Adults of both species foraged mostly in carr when nesting in pure reed marshes, whilst those from mixed marsh nests mostly utilized the marsh. Habitat selection in the Sedge Warbler Acrocephalus schoenobaenus was studied. A separate habitat classification was used, which indicated a preference for nesting in areas with a mixed dense vegetation matrix, consisting mostly of reed and bramble. These areas contained the highest densities of breeding pairs and were occupied first. Evidence was given to support the view that the plant species content within a breeding territory was less important than its vegetative complexity, which was measured and shown to be negatively correlated with settlement time.
Jael:

After a brief analysis regarding the figure of Deborah, with this article we propose a characterization of the figure Jael in the two texts (prose and verse) of Judges 4 and 5, as well as the possible intertextual relations of her figure with specific images and contexts of the time that go back to the memories of these texts, since they are formed by varied multilayers. Despite being a polyphonic narrative in terms of modern narrative analysis theories, we do not fail to consider the memories embedded in the texts analyzed, and which constitute a fundamental role in the resistance of marginalized groups in the context of their writing. To this end, we use Bakhtin's theory of Heteroglossia and also his ideas about the presence of plurality of voices in a narrative, we also use research around Canaanite mythology and the analysis of contextual imagery around specific terms used in these texts. All this we propose in order to construct the image of the character Jael in the most explicit way possible, challenging new research and deepening regarding this imagery for the deconstruction of the silencing process of voices that groups suffered through the production of these texts.
