Authors: Huang Yinghui , Li Mei , Tsung Fugee , Chang Xiangyu 
Published: January 2025

AbstractCustomer satisfaction is crucial for any firm. Traditional methods of measuring customer satisfaction, such as customer surveys, are resource‐intensive despite their effectiveness. We develop an innovative approach that leverages social media posts to evaluate customer satisfaction. Specifically, we augment survey data with social media content and propose a supervised topic model to predict customer satisfaction. Method‐wise, our model accommodates texts from various social media platforms, with or without explicit customer ratings. In addition, we address the challenges associated with integrating multiple data sources. To empirically validate our approach, we utilize data from various social media platforms combined with customer surveys from target firms in seven essential industries in Hong Kong. Our model exhibits higher prediction accuracy compared to baseline methods. This research provides a cost‐effective and efficient tool for transforming vast amounts of social media posts into valuable insights on customer satisfaction.

AbstractPolycarbosilane (PCS) pyrolysis is a common method for synthesizing silicon carbide (SiC). However, the relationship between structure and properties during PCS pyrolysis is not well understood, and monitoring thermomechanical properties during the process is challenging. Few studies have examined the evolution of PCS performance during pyrolysis. Therefore, investigating the evolution of the structure–property relationship during PCS pyrolysis is essential. In this study, a reliable model was developed to track crosslinking, inorganic transformations, and gas release during PCS pyrolysis. Molecular dynamics (MD) simulations were used to elucidate the evolution of the structure–property relationship in PCS‐derived Si–C ceramics. The results show a direct correlation between the microstructure and properties of Si–C ceramics, with our predictions closely matching experimental data. This indicates that these models can effectively estimate thermomechanical properties that are difficult to measure experimentally. Furthermore, our work offers a systematic approach to quantifying the structure–property relationship based on the primary reactions in the pyrolysis system, facilitating the tailoring of the structure to meet specific performance criteria.

SummaryLiterature evidenced an association of maternal sleep disturbances and maternal obstructive sleep apnea with significant obstetric complications. Moreover, the maternal sleep disturbances effect on feto‐placental circulation had not been extensively examined. Our objective is to explore the possible maternal sleep disturbances impact on the feto‐placental indices evaluated through the Doppler study. A systematic review of the following databases was performed: PubMed, EMBASE, Cochrane Library and Google Scholar from the beginning to June 2024. Only studies that enrolled pregnant women with signs and symptoms of maternal sleep disturbances or obstructive sleep apnea diagnosis, which analysed the feto‐placental Doppler parameters, were considered eligible (PROSPERO ID: CRD42024553926). We included a total of four studies with 1715 cases of pregnant women. Various instrumental and non‐instrumental diagnostic methods were adopted for detection of maternal sleep disturbances. The ultrasound exam was performed mainly in the third trimester of pregnancies, and all the studies explored the uterine Doppler parameters. Only two studies explore the foetal Doppler parameters. Only one study disclosed that maternal sleep disturbances are related to altered uterine Doppler indices with probable placental dysfunction. This review did not evidence a significant influence of maternal sleep disturbances and obstructive sleep apnea on foetal Doppler indices. Moreover, one large prospective study showed a possible impact of maternal sleep disturbances on uterine Doppler with a potential impairment of the placentation function. Additional studies with detailed data and larger samples are needed to throw light on this relationship and its impact on the foetal outcomes.
Exploring how structural forms of power shape the training of intraprofessional collaboration between family physicians and specialty physicians in outpatient workplace settings
Authors: Wong René , Whitehead Cynthia R. 
Published: January 2025

AbstractIntroductionIntraprofessional collaboration between family physicians (FPs) and specialist physicians (SPs) is posited to improve patient outcomes but is hindered by power dynamics. Research informing intraprofessional training on hospital wards often conceptualizes power at an interactional level. However, less is known about how social structures make these power dynamics possible. This study explores how structural forms of power shape how FP and SP supervisors engage with and teach intraprofessional collaboration in outpatient settings and to what effect.MethodsUsing diabetes as a case study of intraprofessional collaboration, we conducted a discourse analysis of formal documents (written to guide how collaboration should be practiced) and interview transcripts with 15 FP and SP supervisors. Informed by governmentality and the sociology of professions, we analysed how discourses governing diabetes care shape FPs' and SPs' clinical and teaching behaviours, implications for jurisdictional boundaries and the nature of their collaborative relationships.ResultsDiscourses of evidence‐based medicine construct a hierarchical social structure in medicine that permeates how physicians engage with and teach intraprofessional collaboration. FPs and SPs enact and teach these hierarchical roles when collaborating in the referral‐consultation process in ways that establish and reinforce jurisdictional boundaries. The interactions at the intersection of these boundaries foster a form of collaboration characterized by SPs surveilling and regulating FPs' practices.DiscussionAs currently constructed, intraprofessional collaboration in outpatient settings may be practiced and taught in ways that reinforce asymmetric power dynamics between FPs and SPs. Without awareness of this unintentional effect, educational attempts to advance this constructed notion of collaboration may ironically impede the achievement of collaborative ideals. Outlining the processes by which structural power permeates FPs' and SPs' collaborative behaviours opens space for educators to acknowledge and mitigate the effects of social structures on intraprofessional training in other clinical and educational contexts.

Published: January 2025

SummaryThis is a qualitative systematic review in which we investigated barriers and enablers influencing dietary behavior change after metabolic bariatric surgery (MBS). Database searches retrieved publications reporting perceived factors influencing dietary behavior change post‐MBS. Data (quotes, survey results, interpretative summaries) were extracted and analyzed using combined deductive and inductive thematic analyses. The generated barrier/enabler themes mapped to the Theoretical Domains Framework and then behavior change techniques to identify potential strategies to improve post‐operative dietary behavior. Thirty‐four publications were included. Key barriers fell within the domains of ‘Environmental Context and Resources’ (e.g., insufficient and unreliable healthcare services), ‘Behavioral Regulation’ (e.g., lack of self‐discipline), ‘Emotions’ (e.g., eating as a strategy to overcome negative emotions), ‘Beliefs about Consequences’ (e.g., the extent of realistic expectations from MBS), and ‘Social Influences’ (e.g., challenge of eating at social events). Key enablers were also identified within ‘Environmental Context and Resources’ (e.g. self‐access internet‐based resources), ‘Behavioral Regulation’ (e.g. learning how to develop new dietary strategies), ‘Beliefs about Consequences’ (e.g., positive impacts of surgery‐induced food intolerances), and ‘Social Influences’ (e.g., support from social/group sessions). Potential strategies to change postoperative dietary behavior include social support, problem‐solving, goal setting, and self‐monitoring of behavior. This provides insight into the targets for future post‐operative nutrition‐focused interventions.

Authors: Becker Talia , Kuperberg Mishel Kleinerman , Domb David 
Published: January 2025

AbstractAimsTo assess and compare the effectiveness of pharmacological and cognitive‐behavioral modalities—behavioral methods (BM), nitrous oxide inhalation sedation (NOIS), and premedication with Diazepam—for alleviating anxiety during dental treatment, using completed treatment sessions and adverse outcomes as indicators.Methods and resultsFor 239 patients (515 dental records), 18–53 y/o, who underwent dental treatments under anxiety reduction measures, sessions under NOIS were categorized as “nitrous group” (456 sessions) versus premedication with Diazepam or behavioral strategies (control, 59 sessions). Outcomes were completed treatment sessions considering demographic and clinical parameters, and adverse outcomes during and between sessions.Adjusted logistic regression showed significantly higher odds of completing treatment sessions after NOIS (p = 0.014) as compared to controls. Univariate analyses demonstrated failure of anesthesia was higher in the control versus the nitrous group (p < 0.001). Adverse outcomes were more frequent in controls (p = 0.005). No significant effects of age, gender, and general health condition on completion rates of treatment plans were demonstrated. The complexity of the treatment plan had a significant effect on its completion (p = 0.03).ConclusionsNOIS modality yielded significantly superior outcomes as compared to BM and premedication with Diazepam, with no significant effects of age or gender on the completion of treatment plans.
Stability of Tollmien–Schlichting Modes in Magnetohydrodynamic Boundary Layer Flow in Porous Medium: Energy Budget Analysis
Authors: M. C. Bharathi , Kudenatti Ramesh B. 
Published: January 2025

Abstract
Linear temporal and spatial stability analyses of the magnetohydrodynamic boundary layer flow over a wedge embedded in a porous medium have been carried out to analyze the effects of pressure gradient, Hartmann and Darcy numbers. First, we determine the base state velocity profiles by imposing suitable similarity transformations on governing boundary layer equations and then find linear perturbed equations involving Reynolds number and disturbance wavenumber using Fourier modes. The Chebyshev spectral collocation method which provides insight into the complete structure of the eigenspectrum is used. The effect of Hartmann and Darcy numbers on the boundary layer is to stabilize the flow for all adverse pressure gradient parameters while only unstable modes are noticed in the absence of these effects. The noticed unstable modes are always part of the wall mode for which the phase speeds are found to approach zero. The eigenspectrum for all involved parameters has a balloon-like structure with the appearance of wall mode instability. The critical Reynolds number is found to be increasing for increasing pressure gradient, Hartmann and Darcy numbers. For an adverse pressure gradient, the energy budget shows that the energy production due to Reynolds stress dominates the viscous dissipation which results in destabilization of the flow, while the kinetic energy due to magnetic field and porous medium plays a role in stabilizing the flow. The physical dynamics behind these interesting modes are discussed.
Identification and functional characterization of a fructose-inducible phosphotransferase system in
Azospirillum brasilense
Sp7
Authors: Rai Sushant , Singh Vijay Shankar , Gupta Parikshit , Tripathi Anil Kumar 
Published: January 2025

ABSTRACT

Plant growth-promoting rhizobacterium
Azospirillum brasilense
Sp7 utilizes fructose efficiently via a fructose phosphotransferase system (Fru-PTS). Its genome encodes two putative Fru-PTS, each consisting of FruB (EIIA), FruK (Pfk), and FruA (EIIBC) proteins. We compared the proteomes of
A. brasilense
Sp7 grown with malate or fructose as sole carbon source, and noticed upregulation of the constituent proteins of Fru-PTS1 only on fructose. Inactivation of
fruA
gene of both the Fru-PTS showed that Fru-PTS1 is the main PTS involved in fructose utilization. Overexpression of
fruA1
in
A. brasilense
Sp7 enhanced its growth on fructose showing improved consumption of fructose. This suggested that fructose utilization in
A. brasilense
Sp7 is limited due to the limitation of EIIBC component. A FruR-type regulator, encoded divergently to the Fru-PTS1 operon, was required for chemotaxis toward fructose. Although not an absolute necessity for the growth of fructose, FruR was required for the optimal growth of fructose. The
fruB1
promoter was activated by fructose and repressed by malate, but FruR does not seem to regulate its expression. A 27-nucleotide stem-loop structure located between the −125 and −99 promoter proximal region of
fruB1
was involved in fructose inducibility and malate repression. Fructose also upregulated several proteins involved in the biogenesis of a Type 6 secretion system. Here, we have shown that
A. brasilense
Sp7 was able to inhibit the growth of
Escherichia coli
and
Agrobacterium tumefaciens
in the presence of fructose, and that an intact T6SS was required for contact-dependent growth inhibition of the two Gram-negative bacteria.

IMPORTANCE

Azospirillum brasilense
, a plant growth-promoting rhizobacterium, has limited ability to utilize carbohydrates and sugars. Although it is known to utilize fructose via a fructose phosphotransferase system (fructose-PTS), the genes involved in fructose utilization and the role of fructose in its biology were not well characterized. This study has shown that out of the two units of fructose-PTS encoded in its genome, fructose-PTS1 plays the major role in fructose utilization. Overexpression of the membrane component (EIIBC) improved the growth of
A. brasilense
on fructose. The ability of fructose to induce proteins of the Type 6 Secretion System (T6SS) enables
A. brasilense
to cause contact-dependent inhibition of the growth of
Escherichia coli
as well as
A. tumefaciens
. This is the first report on the fructose inducibility of T6SS in
A. brasilense
, which may provide a handle to control the growth of undesirable bacteria using T6SS of
A. brasilense
in a mixed culture.
Structural conservation and functional role of TfpY-like proteins in type IV pilus assembly
Authors: Qaderi Ikram , Chan Isabelle , Harvey Hanjeong , Burrows Lori L. 
Published: January 2025

ABSTRACT

Type IV pili (T4P) are important virulence factors that allow bacteria to adhere to and rapidly colonize their hosts. T4P are primarily composed of major pilins that undergo cycles of extension and retraction and minor pilins that initiate pilus assembly. Bacteriophages use T4P as receptors and exploit pilus dynamics to infect their hosts. Some bacteria encode pilin accessory proteins that post-translationally glycosylate major pilins to evade phage binding. TfpY is an accessory protein of unknown function that is widespread and structurally conserved among T4P-expressing bacteria. Here, we use
Pseudomonas aeruginosa
as a model to characterize the functional role of TfpY and its homologues in pilus assembly. TfpY expression is required for optimal pilus assembly and function; however, it does not provide phage defence, unlike previously characterized accessory proteins. TfpY can cross-complement twitching in strains expressing heterologous
P. aeruginosa
pilins, suggesting TfpY and its homologues play a common role in pilus assembly. We showed that TfpY likely interacts with the major pilin and specific minor pilins but is not incorporated into the pilus itself. We propose that TfpY, along with the minor pilins at the pilus tip, primes pilus assembly. We identified two unique gain-of-function mutations in T4P regulatory genes that non-specifically restore twitching in
tfpY
mutants by increasing levels of cAMP and expression of T4P components. This study enhances our understanding of the complex functional and regulatory relationships between pilin and accessory proteins.

IMPORTANCE

Type IV pili are surface filaments that enable versatile pathogens, like
Pseudomonas aeruginosa
, to adhere to and colonize surfaces. Pili are composed of diverse proteins called pilins, which serve as host receptors for phages.
P. aeruginosa
uses specific accessory proteins to glycosylate pilins to evade phage infection. Here, we show that TfpY is a conserved accessory protein that does not mediate phage defence. Instead, we propose a mechanism where TfpY facilitates efficient pilus assembly and function. A better understanding of TfpY function will provide insight into how its associated pilins have evolved to resist phage infection in the absence of post-translational modification, how some phages overcome this barrier to infection, and how this can guide the design of phage-based therapeutics.

Published: January 2025

ObjectivePerinatal epidemiological studies and outcomes are often reported on gestational week thresholds. This study aims to quantify and investigate the association of each gestational day at birth on antenatal management, mortality and respiratory outcomes of extremely preterm infants.DesignRetrospective cohort study using National Neonatal Research Database.SettingEngland and Wales.Patients26 098 infants born <28 weeks of gestational age (GA) and admitted to neonatal units from 2010 to 2020.InterventionsAntenatal care and outcome measures for each gestational day were described with 95% CI determined using Agresti-Coull method. χ2test for trend assessed the trends across gestational day. Analysis of means assessed if outcome on each gestational day differed from the overall outcome for that gestational week.Main outcome measuresMortality and respiratory disease.ResultsNeonatal admissions peaked at the start of each gestational week. Caesarean section was the most common birth mode from 26+1to 26+4weeks GA. Mortality and severe respiratory morbidity decreased with each day of gestation within the gestational week threshold (p<0.01). Mortality at the beginning and end of each gestational week differed from the overall mortality for that gestational week (p=0.03 to <0.001) in infants <27+0weeks GA. Mortality was higher in infants <26+0weeks GA born to mothers without complete antenatal corticosteroid course or born in centres without neonatal intensive care units.ConclusionsEach day of gestation is important for extremely preterm infant outcomes. Perinatal decision-making, counselling and reporting should avoid broad gestational weeks and include day of gestation.
Factors influencing virtual reality use in paediatric acquired brain injury upper limb rehabilitation: a qualitative study
Authors: Rathinam Chandrasekar , Farr William , Ray Daniel , Gupta Rajat 
Published: January 2025

ObjectiveUpper limb movement difficulties in children with acquired brain injury (ABI) result in longer recovery times compared with lower limb. Intensive neurorehabilitation promotes a good long-term functional outcome. Virtual reality (VR) and video game technologies are invaluable adjuncts to traditional neurological rehabilitation as they help to motivate, engage and gain children’s compliance in goal-directed therapy. However, this technology is not routinely used in the National Health Service, UK; it requires embedding to benefit children and their families. VR implementation in rehabilitation practice requires development. The associated influencing factors require further exploration before routine use can be established. This project aimed to understand the factors influencing the use of VR in upper limb rehabilitation in children.VR implementation in rehabilitation practice requires development. The associated influencing factors require further exploration before routine use can be established. This project aims to understand the factors influencing the use of VR in upper limb rehabilitation in children.DesignAn interpretative qualitative study used focus groups and 1:1 semi-structured interviews conducted in person and online to explore participants’ experiences. These were analysed for inductive overarching themes, particularly focusing on the views of professionals and young people regarding the use of VR in upper limb rehabilitation.SettingTwo neurorehabilitation services located in two children’s hospitals in England, UK.ParticipantsThree physiotherapists, five occupational therapists, a play worker and four members from the Young Persons’ Advisory Group took part. Four focus groups with 2–4 participants in each group and two 1:1 semi-structured interviews were conducted. Thematic analysis was used to create the model participants described as the factors that influenced the use of VR in neurorehabilitation.ResultsFive closely related major themes and thirty associated subthemes were developed: training, knowledge, promotion, consideration of barriers and family factors. There is a lack of knowledge and understanding about the use of VR, its limitations, and the clinicians’ motivation to use it. Training packages with available VR equipment, clinical indicators and scientific evidence are required. Staff need frequent training, logistics (uninterrupted Wi-Fi, software, hardware) and simple instruction manuals.ConclusionTo introduce VR into the routine rehabilitation of children with ABI, investment in improving knowledge, frequent training and positive behaviour change among health professionals is needed.
