Authors: Okhrimchuk Ye.
Published: February 2023

This article discusses how new technological options for industrial enterprises provide a simple approach to solving production problems and achieving economic growth. The main goal of this study is to analyze the effectiveness of existing industrial Internet of Things solutions, to determine the current state of technology and its relevance in the current crisis period. In its most general form, the implementation of the IIoT strategy involves connecting sensors and automated systems located in complex manufacturing and process locations to create a single data network. The study presents the general architectural elements of the industrial Internet of Things ecosystem and considers the IIoT and IT-OT system convergence system in the form of a multi-level scheme, explains the fundamental difference between IoT and IIoT technologies. Using the example of European countries, the level of technology integration at enterprises was analyzed, depending on the size and implementation goals. Depending on the size of the enterprise, there can be significant differences in the use of IIoT, so in large enterprises the studied technologies are used almost twice as much. It was determined that the largest share of investments falls on the sphere of security provision and support - 72% on average. It is noted that Covid-19 had the greatest positive impact on the accelerated implementation of IIoT technologies. The main benefits obtained by processing and analyzing data from smart sensors and sensors are described, and their application to specific goals is explored. At the same time, the main problems facing business and the government are listed. The impact of the Ukrainian-Russian conflict on the technological sector was analyzed, which led to problems with the logistics of important elements for the production of semiconductor microcircuits and expanded the list of possible risks from the introduction of digital technologies into production. Overall, growth in the number of connected devices slowed in 2021, but is expected to accelerate again in 2022 and beyond. Although new hurdles have emerged in the IoT market, the overall sentiment in the industry remains relatively positive.

Published: February 2023

Ensuring employment of young people in the EU and the use of this political and legal experience in Ukrainian realities is a rather urgent issue. The article systematizes and investigates the current state and causes of youth unemployment in EU countries. It was determined that the unemployment rate among young people steadily increased during the period 2008-2013, which affected the EU economy, however, until 2019, a consistent decline was observed. The main factors influencing this indicator are the following: lack of vacancies for inexperienced youth, natural employee turnover, economic downturn, etc.
The normative and legal support of youth employment policy was considered, in particular employment policy aimed at post-pandemic recovery. The main regulatory acts of youth employment policy in the EU are defined as European Pact for Youth, Resolution "Youth Employment Crisis: A Call to Action", "Framework Action Program on Youth Employment" and others.
European programs and initiatives aimed at reducing youth unemployment, as well as improving education and labour mobility are analysed. The main European programs and initiatives are defined as NextGenerationEU, the Strategy "Youth - investing and providing opportunities", the "Youth opportunities" initiative, "Involvement of youth in employment" and others. They include creating more opportunities for young people in education and employment, improving access and full participation in society, developing skills relevant to the labour market, supporting first work experience and workplace learning, etc. It is emphasized the need to stimulate the economic growth of the EU member states, focusing on the youth segment, implementing employment support programs adapted to the current situation in the world.

Published: February 2023

The article presents the research results of partnership marketing tools. The relevance of the work is related to the annual increase in the level of competition and the need for companies to unite with other brands to achieve common goals, which ensures the further development of the enterprise. The work aims to systematize the main tools of partnership marketing. The tasks of the work are to identify the main partnership tools, categorize them, and choose those that can be used in small and medium-sized businesses. The benefits of partnership marketing include increased reach, load sharing, word of mouth, and increased value for consumers. Partnership marketing tools used by most companies were singled out: affiliate marketing, content partnership, sponsorship, joint products, distribution partnership, shared stores, product placement, loyalty programs, licensing, outsourcing, and joint ventures. Varieties and formats were defined for each of them. Benefits for the leading brand were identified: increased brand awareness, improved reputation, increased sales, activity, awareness of products and services, access to resources, increased visibility in search engines, increased customer retention, increased visit duration, saving time, money, resources, and avoiding system failures. Benefits for the secondary brand: increased sales, additional income, increased awareness of the company, access to the resources and audience of the primary brand, attracting new customers, and compensation for the cost of purchasing goods. Indicators for tracking the effectiveness of cooperation for each tool were determined: return on investment, coverage, stock turnover rate, number of new and potential customers, and conversion rate. The usual advantages of partnership marketing include increasing market coverage among existing and potential customers; workload distribution for the duration of the project and the opportunity to work with fantastic talent without having to deal with the hiring process; spreading information through word-of-mouth about a product or service; increasing value for your audience. It has been found that small and medium businesses can use all of the above as a partner, except for product placement, and only affiliative marketing, content partnership, partnership distribution, shared stores, and licensing as an initiator.

Authors: KALAYCIOĞLU Zeynep
Published: February 2023

Chemical properties of grape, cranberry, blueberries, pomegranate, black mulberry, juniper, and carob pekmez samples were investigated in this study. Capillary electrophoresis was used to assess the organic acids and sugar levels of pekmez samples. The two main sugars were found to be as glucose and fructose. Juniper pekmez has the lowest sugar with 22.6 g /100 g glucose and 20.1 g /100 g fructose. Black mulberry (35.6 g/100 g) has the highest glucose whereas grape (45.8 g /100 g) includes the highest fructose. Each pekmez samples included 8 organic acids which are oxalic, tartaric, malic, citric, succinic, acetic, lactic, and gluconic acid. 1,1-diphenyl-2-picryl-hydrazil (DPPH) technique was applied for testing the antioxidant activities. Carob pekmez scavenged DPPH the most with 96.28% inhibition value. The other pekmez samples have inhibited DPPH with the values ranging between 58.04% (cranberry) to 90.16 (juniper). The samples' total phenolic levels ranged from 265 mg GAE/g (blueberry) to 1070 mg GAE/g (grape). Moisture contents were measured using a moisture analyzer. Cranberry pekmez (19.06%) and grape pekmez (12.24%) have significantly the highest moisture compared to other samples changing between 2.41% and 5.10%.

Authors: Grechukhin A. N. , Kuts V. V. , Pavlov D. A.
Published: February 2023

Purpose of research. Locking mechanisms have been widely used to connect elements of vertical formwork structures consisting of metal frames and shields fixed to them. The purpose of the study is to develop the design of the locking mechanism for the elements of removable formwork, which has high technological characteristics. A patent search was conducted for existing design solutions to ensure the connection of elements of removable formwork. It has been revealed that the most common structures used in the locking mechanisms of removable formwork elements are rack-and-pinion structures. The analysis of existing structures is carried out, the shortcomings of existing devices are revealed. It is established that the existing designs of locking mechanisms for connecting elements of removable formwork have low manufacturability of individual elements. In this regard, in order to solve the research problem, the design of the locking mechanism was developed, which ensures the connection of the elements of the removable formwork. A distinctive feature of the application of the new design of the locking mechanism for connecting the elements of removable formwork is the use of a new design of the toothed rail, which is more technologically advanced in manufacturing, compared with existing designs. Another distinctive feature is the use of a wedge with smooth edges, which also increases the manufacturability of the construction of the device for connecting the elements of removable formwork. To achieve this goal, an analytical research method was applied. The use of the proposed design will increase the manufacturability of the manufacture of locking mechanisms for connecting elements of removable formwork. The proposed design of the locking mechanism for connecting the elements of removable formwork, developed as a result of the study, has design features related to operating conditions. These features will be considered as a result of further research.

Methods. Simulation modeling methods were used to conduct the experiments.

Results. The range of sizes of the main structural elements of the locking mechanism for connecting the elements of removable formwork, ensuring the operation of the device under the action of design loads, is determined.

Conclusion. The results of the study showed that the existing designs of locking mechanisms for connecting elements of removable formwork have disadvantages, one of which is the low manufacturability of the devices. The design of the locking mechanism has been developed, which provides higher manufacturability. The proposed device can be used in construction to connect elements of fixed formwork.

                                                            ABSTRACT

Background: Providing enteral nutrition to ICU patients is often challenging, leading to sufficient enteral nutrition that is hardly achieved. This condition is caused by gastrointestinal motility disorder and other complications that often happen during enteral nutrition provision. Therefore, it is important to understand the level of nutritional support and the challenges in the form of interruption during enteral nutrition to critically ill patients receiving mechanical ventilation to optimise the benefit of nutritional support for patients, including reducing the duration of hospitalisation and mortality.

Objectives: This study aims to evaluate the provision of enteral nutrition and identify the cause of interruption for patients with mechanical ventilation in one of the tertiary hospitals in Yogyakarta, Indonesia who receive enteral nutrition.

Methods: This is a cross-sectional study. The subject of the study is patients who fulfil the inclusion and exclusion criteria. Inclusion criteria include patients who were in ICU for ≥72 hours, receiving mechanical ventilation. While the exclusion criteria include patients with contraindications for enteral nutrition such as unstable haemodynamic, bowel obstruction, persistent severe ileus, gastrointestinal bleeding, nasogastric tube (NGT) placement is not possible, patients receiving oral nutrition with non-invasive ventilation, patients with feeding tube before admission, or patients from other ICU or HCU.

Results: Patients needed, on average, 13 hours to receive initial enteral nutrition (SD ± 9.89 hours), with a period between 0 – 50 hours since admission to ICU. The mean time for patients to receive full feeding is 4 days ± 2.4 days. On the other hand, 16 out of 75 patients (21.2%) did not reach the targeted intake during admission. The cause of the interruption of enteral nutrition includes gastric residual volume (GRV), percutaneous dilatation tracheostomy (PDT) procedure, vomiting, bloating, surgery, CT scan, etc.

Conclusion: Many causes of interruption and inadequate intake of enteral nutrition can be prevented. The absence of protocol agreed upon by the patient care team could be one of the influencing factors.

Published: February 2023

Background

Despite extensive debates about the mental health impacts of the use of social networking sites (SNSs), including WeChat, the association and mechanisms between social interaction of WeChat use intensity and antenatal depression are unclear.

Objective

We aimed to test the mediating roles of upward social comparison on social interaction of WeChat and rumination in the association between social interaction of WeChat use intensity and antenatal depression.

Methods

A cross-sectional survey was conducted in four hospitals with the self-reported measures of social interaction of WeChat use intensity, upward social comparison on social interaction of WeChat, rumination, antenatal depression, and control variables. The mediation analysis was performed through Model 6 from the PROCESS macro 4.0 in SPSS 26.

Results

Results from 2661 participants showed that antenatal depression was unrelated to social interaction of WeChat use intensity (P=.54), but was significantly positively related to the attitude toward social interaction of WeChat (P=.01). The direct effect of attitude toward social interaction of WeChat use on antenatal depression was not statistically significant (β=–.03, P=.05). The results supported an indirect relationship between attitude toward social interaction of WeChat use and antenatal depression via (1) upward social comparison on social interaction of WeChat (indirect effect value=0.04, 95% CI 0.03 to 0.06); (2) rumination (indirect effect value=–0.02, 95% CI –0.04 to –0.01); and (3) upward social comparison on social interaction of WeChat and rumination in sequence (indirect effect value=0.07, 95% CI 0.06 to 0.08).

Conclusions

Our findings highlight the necessity of focusing on attitudes toward SNS use, and the importance of upward social comparison and rumination in understanding the effect of SNS use on antenatal depression.
Trust perspective on “MyData” health ecosystem: Citizen-centered data management solution in Finland (Preprint)
Authors: Wang Fan , Gomes Julius , Pikkarainen Minna , Ahokangas Petri
Published: February 2023

BACKGROUND

MyData principles for delivering health services aims to utilize citizen-centered data and engage individuals in managing personal health data, evaluating their health conditions, gaining healthcare support, changing their behavior and lifestyle accordingly, and sharing their data across boundaries among individuals, private and public organizations, and research institutions. In this context, the issue of the trust and trustworthiness of institutions involved is becoming more important than in the traditional digital health ecosystems due to the sensitivity of personal health data.

OBJECTIVE

This study aims to identify factors that influence the MyData ecosystem’s trustworthiness and create appropriate conditions for optimizing the effects of trust and risk on the data sharing perceived by multiple stakeholders to build the trustworthiness of the MyData digital health ecosystem in Finland.

METHODS

The empirical analysis was primarily based on 30 semi-structured interviews with multiple stakeholders conducted in Finland in November 2021 and February 2022. Iterative workshops from two large-scale Finnish digital healthcare research projects on health data management, artificial intelligence (AI) solutions in future healthcare, and cooperative digital health solutions adoption were also utilized as secondary materials to understand the complex phenomenon of trust in the MyData digital health ecosystem.

RESULTS

The perceived technological and data trust, institutional trust, and legitimated trust were found to be relevant and important through perceived communication, empowerment, and social influence to build the MyData digital health ecosystem for securing personal health management and sharing.

CONCLUSIONS

The findings emphasize the critical role trust plays in engaging multiple stakeholders in the MyData health ecosystem and promoting the fair and secondary uses of personal health data in digital health, particularly for preventive healthcare purposes.

Honduras is the second country in central America along with Panamá with the greatest bat diversity, and the insectivorous bats are the most diverse in the Chiroptera order. The family Mormoopidae has the largest number of records in Honduras and these bats are important as pest control in crops where they are present. To understand the importance of the Mormoopidae family in Honduras, we need to know where it is distributed. A species distribution model is a tool that provides information on the distribution of the species, based on presences records and climate variables. We collected information from free access databases like GBIF, reports, and paper publication to obtain presence data in Honduras. To run the models, we used Maxent in dismo package. Our results show a similar distribution for all species of Mormoopidae family, the principal causes that limited the distribution of the species are ecosystem type and altitude; some species tolerated evergreen forest and others prefer dry forest, in terms of elevation, in some species is limited from lowland to 1500 m.a.s.l., like Mormoops megalophylla, Pteronotus psilotis, and Pteronotus gymnonotus, and others can inhabit above 2800 m.a.s.l., like Pteronotus fulvus, and Pteronotus mesoamericanus. We need to obtain more records of species like M. megalophylla, P. psilotis, and P. gymnonotus. More surveys in the eastern part of Honduras are necessary where there are many information gaps, this would help us to have more robust models and a better understanding of the distribution of these species.

Abstract: The Internet of things (IoT) is the system of gadgets, vehicles, and home machines that contain hardware, programming, actuators, and network which enables these things to interface, collaborate and trade information. IoT includes broadening Internet network past standard device, for example, work areas, workstations, cell phones and tablets, to any scope of generally stupid or non-web empowered physical device and ordinary articles. Installed with innovation, these gadgets can convey and connect over the Internet, and they can be remotely observed and controlled [1]. The meaning of the Internet of things has advanced because of union of numerous innovations, ongoing examination, AI, ware sensors, and implanted frameworks. Conventional fields of installed frameworks, remote sensor systems, control frameworks computerization (counting home and building mechanization), and others all add to empowering the Internet of things. A gas spill alludes to a hole of petroleum gas or different vaporous item from a pipeline or other regulation into any territory where the gas ought not be available. Since a little hole may steadily develop a hazardous convergence of gas, spills are perilous.

Efficient color code decoders in d≥2 dimensions from toric code decoders
Authors: Kubica Aleksander , Delfosse Nicolas
Published: February 2023

We introduce an efficient decoder of the color code in d≥2 dimensions, the Restriction Decoder, which uses any d-dimensional toric code decoder combined with a local lifting procedure to find a recovery operation. We prove that the Restriction Decoder successfully corrects errors in the color code if and only if the corresponding toric code decoding succeeds. We also numerically estimate the Restriction Decoder threshold for the color code in two and three dimensions against the bit-flip and phase-flip noise with perfect syndrome extraction. We report that the 2D color code threshold p2D≈10.2% on the square-octagon lattice is on a par with the toric code threshold on the square lattice.
Entrepreneurial orientation, entrepreneurial resources, and entrepreneurial success: The need for further exploration
Authors: Duong Doanh
Published: February 2023

Starting new businesses is important for the social and economic development of each country (Esfandiar et al., 2019; Fayolle & Liñán, 2014). However, research on starting a business has so far been more about clarifying the influence of factors on the intention of starting a business (Duong, 2022; Ghosh, 2022; Loan et al., 2021; Vasilev, 2022; Vuong et al., 2020), and there have not been many studies on entrepreneurial success—the determinant of the meaning of starting a business (Wang et al., 2023; Welsh et al., 2023). Entrepreneurial success is defined as a complex phenomenon, and it covers both financial and non-financial criteria (Glosenberg et al., 2022). Initially, entrepreneurial success is often equated to financial/economic indicators (Staniewski & Awruk, 2019). For example, it includes business efficiency, growth rate, profitability, liquidity, market share (Glosenberg et al., 2022), and staff growth rate (Welsh et al., 2023). Meanwhile, it is criticized that, if “entrepreneurial success” is measured only by financial (or economic) indicators, it is difficult to fully reflect the meaning of this term and it should not be limited in one way (Cumming et al., 2022). Entrepreneurial success does not necessarily equate to wealth, and researchers are very interested in entrepreneurs' work-life balance (Yu et al., 2022).
Resident Self-assessment and Clinical Competency Committee Evaluations in Family Medicine: A Single-Institution Study
Authors: Bhardwaj Namita , Porterfield Laura , Kuo Yong-Fang , Campbell Kendall M.
Published: February 2023

Background and Objectives: We sought to describe the process of integrating resident self-assessments into milestone assessments at the University of Texas Medical Branch Family Medicine Residency Program in Galveston, Texas. We compared resident self-assessments across milestones to Clinical Competency Committee (CCC) assessments across terms (fall versus spring) and by postgraduate year (PGY).
Methods: In fall 2020, the milestone assessment process was updated to include a resident milestone self-assessment, which was used as the starting point for CCC assessment. We calculated mean and standard deviation of average milestone scores for both self-assessment and CCC for each PGY. We used repeated measure analysis of variance to examine within- and between-subject effects.
Results: Self-assessment and CCC assessments were completed for 30 postgraduate trainees for spring 2020 and fall 2021 terms, for a total of 60 self- and 60 CCC assessments. CCC score was similar to self-assessment. There were larger variations in the resident self-assessment scores than CCC scores. Self-assessment scores increased by PGY, but were not different between fall and spring terms. We found a significant three-way interaction of assessors, terms, and PGYs.
Conclusions: Resident milestone self-assessment enables residents to participate in the assessment process, and when differences exist between self- and CCC assessments, specific feedback can be given based on individual milestone skills. Our study showed progression between PGY regardless of the assessor, but only CCC assessment showed significant differences between terms.

Background and Objectives: Successful clerkship directors (CDs) must exhibit a variety of leadership, administrative, educational, and interpersonal skills. This study investigates the professional development needs for family medicine CDs to be successful in their role, in relation to career stage, institutional support, and needed resources.
Methods: A cross-sectional survey of CDs at qualifying United States and Canadian medical schools was performed between April 29, 2021 and May 28, 2021. Questions addressed specific training when beginning CD position, professional development activities that have contributed to success, additional professional development skills required to be a successful CD, and planned future development activities. We utilized χ2 square and Mann-Whitney U tests for comparisons.
Results: Surveys were completed by 75 CDs, for a response rate of 48.8%. Only 33.3% of respondents reported receiving training specific to their role as CD. The majority of respondents cited informal mentoring and conference attendance as important to their professional development, but none identified graduate degrees as the most important method of professional development.
Conclusions: These findings demonstrate the lack of formal training provided to CDs and highlight the importance of informal training and conference attendance for professional development.

Published: February 2023

Introduction: Academic promotion is an important goal in an academic physician’s career trajectory. Understanding the factors that influence success in academic promotion is important in providing appropriate guidance and resources.
Methods: The Council of Academic Family Medicine Educational Research Alliance (CERA) conducted a large omnibus survey of family medicine department chairs. Participants were asked about recent promotion rates within their department, as well as about whether their department had a promotion committee, whether faculty regularly met with the chair regarding preparation for promotion, whether faculty had been assigned mentors, and whether faculty attended national academic meetings.
Results: The response rate was 54%. Most chairs were male (66.3%), White (77.9%), and aged 50 to 59 (41.3%) or 60 to 69 (42.3%) years. Attendance at professional meetings was associated with a higher rate of assistant-to-associate professor promotions. Departments with a committee to help faculty with promotions had higher rates of promotion for both assistant-to-associate and associate-to-full professor levels than departments without a committee. Promotion was not associated with assigned mentorship, support from the chair, departmental or institutional sponsorship of faculty development regarding promotion, or annual assessments of progress toward promotion.
Conclusions: Attendance at professional meetings and the presence of a departmental promotions committee may be helpful factors in achieving academic promotion. An assigned mentor was not found to be a helpful factor.

Published: February 2023

La economía al ser categorizada como una ciencia, inmediatamente pasa a ser una materia rígida, muy estructurada que debe cumplir con ciertos parámetros, para satisfacer de manera óptima las necesidades humanas. Precisamente, al mostrar interés en el ser humano, la visión debe expandirse para enfocarse no solo en leyes, normas y lógicas del mercado económico, sino también, considerar las interacciones socio-culturales y ambientales e inclusive el equilibrado y balanceado aspecto individual, ya que estos indicadores pueden determinar el comportamiento racional o ideal de consumo de las personas dentro de un mundo altamente competitivo. En este sentido, el presente artículo de reflexión plantea una nueva visión de la economía consumista donde la tendencia apunta a un equilibrio de la visión individual con la concientización social, cultural e inclusive ambiental, aspectos potenciados este milenio por los ODS y por las consecuencias de la pandemia del Covid 19.

Sorghum is a food staple for millions of people in sub-Saharan Africa,
but parasitic weeds of the Striga genus greatly diminish its production.
An efficient and cost-effective way of managing Striga in
smallholder farms in Africa is to deploy resistant varieties. Here, we
leverage genomics and the vast genetic diversity of sorghum –
evolutionarily adapted to cope with Striga parasitism in Africa
– to identify new Striga-resistant sorghum genotypes. We exploit
a Striga resistance mechanism that hinges on essential
communication molecules – strigolactones exuded by hosts to trigger
parasite seed germination. We used the Sorghum Association Panel (SAP)
to search for sorghum genotypes with a mutation on the LOW
GERMINATION STIMULANT 1 ( LGS1) locus that makes them
ineffective in inducing Striga germination. Our analysis led us
to identify new lgs1 sorghum genotypes which we named SAP
lgs1. SAP lgs1 had the SL exudation profile of known
lgs1 sorghum whose hallmark is the production of the low inducer
of germination, orobanchol. Laboratory and field resistance screens
showed that the SAP lgs1 genotypes also exhibited remarkable
resistance against Striga. Our findings have far-reaching
implications for improving food security in Africa by potentially
reducing crop losses due to Striga parasitism.

Functional connectivity (FC) during sleep has been shown to break down
as non-rapid eye movement (NREM) sleep deepens before returning to a
state closer to wakefulness during REM sleep. However, the specific
spatial and temporal signatures of these fluctuations in connectivity
patterns remain poorly understood. The goal of this study was to
investigate how frequency-dependent network-level FC fluctuates during
nocturnal sleep in healthy young adults using high-density
electroencephalography (hdEEG). Specifically, we examined
source-localized FC in resting-state networks during NREM2, NREM3, and
REM sleep in the first three sleep cycles of 29 participants. Our
results showed that FC within and between all resting-state networks
decreased from NREM2 to NREM3 sleep in multiple frequency bands and in
all sleep cycles. The data also highlighted a complex modulation of
connectivity patterns during the transition to REM sleep whereby delta
and sigma bands hosted a persistence of the connectivity breakdown in
all networks, whereas a reconnection was observed in the default mode
(DMN) and the attentional networks in frequency bands characterizing
their organization during wake (i.e., alpha and beta bands,
respectively). Finally, all network pairs (except the visual network)
showed higher gamma-band FC during REM sleep in cycle three compared to
earlier cycles during the night. Altogether, our results unravel the
spatial and temporal characteristics of the well-known breakdown in
connectivity observed as NREM sleep deepens. They also shed light on a
complex pattern of connectivity during REM sleep that is consistent with
both breakdown and reconnection processes that are network- and
frequency-specific.
Diagnosis of congenital bronchobiliary fistula in children by bilirubin crystallization in the bronchoalveolar lavage fluid: A case report and literature review

Published: February 2023

Background: Congenital bronchobiliary fistula (CBBF) is a rare
disease with abnormal connection between the biliary tract and the
bronchus. The misdiagnosis rate of CBBF is high, delayed surgery may
induce poor outcome. Case presentation: We reported a girl with
CBBF who was confirmed via bronchoscopy and chest computed tomography
(CT). The girl was 7-month-old admitted to the hospital with “recurrent
pneumonia”. Bilirubin crystallization detection was positive in the
bronchoalveolar lavage fluid (BALF). CT images showed the abnormal
traffic between the biliary tract and the right main bronchus, the girl
was diagnosed with CBBF and recovered after surgical operation.
Literature search: A total of 27 cases were collected, 14
(51.8%) cases were diagnosed in the neonatal period, 9 (33.3%)
patients were diagnosed in infancy. CBBF was more common in female
(19/27, 70.3%). The specific manifestations were bilious sputum (24/27,
88.9%) and bilious vomiting (7/27, 22.2%). Recurrent pneumonia (9/27,
33.3%) was common clinical manifestations. The most abnormal fistula
originates different location around the carina was right main bronchus
(21/27, 77.8%). There were 23(85.2%) cases recovered after surgical
operation and 4(14.8%) cases with severe comorbidities/complications
died. Conclusions: CBBF should be suspected in infants with
bilious sputum. Bronchoscopy plays crucial role in preoperative
evaluation and postoperative follow-up. With early diagnosis and
surgery, the prognosis is quite well for CBBF patients without severe
biliary malformation and/or severe postoperative complications.
PATHOGENESIS OF NON-TYPEABLE HAEMOPHILUS INFLUENZAE INFECTIONS IN CHRONIC SUPPURATIVE LUNG DISEASE
Authors: Chatziparasidis Grigorios , Kantar Ami , Grimwood Keith
Published: February 2023

The respiratory tract antimicrobial defense system is a multilayered
defense mechanism that relies upon mucociliary clearance and components
of both the innate and adaptive immune systems to protect the lungs from
inhaled or aspirated microorganisms. One of these potential pathogens,
non-typeable Haemophilus influenzae ( NTHi), adopts
several, multifaceted redundant strategies to successfully colonize the
lower airways and establish a persistent infection. NTHi can
impair mucociliary clearance, express multiple multi-functional adhesins
for various cell types within the respiratory tract and evade host
defenses by surviving within and between cells, forming biofilms,
increasing antigenic drift, secreting proteases and antioxidants, and by
host-pathogen cross-talk, impair macrophage and neutrophil function.
NTHi is recognized as an important pathogen in several chronic
lower respiratory disorders, such as protracted bacterial bronchitis,
bronchiectasis, cystic fibrosis and primary ciliary dyskinesia. The
persistence of NTHi in human airways, including its capacity to
form biofilms, results in chronic infection and inflammation, which can
ultimately injure airway wall structures. The complex nature of the
molecular pathogenetic mechanisms employed by NTHi is
incompletely understood but improved understanding of its pathobiology
will be important for developing effective therapies and vaccines,
especially given the marked genetic heterogeneity of NTHi and its
possession of phase-variable genes. Currently, no vaccine candidates are
ready for large phase III clinical trials.

Published: February 2023

The aim of this paper was to investigate effects of inulin and
ultrasonic homogenization on particle size distribution and
microstructure of oil-in-water emulsion gels stabilized by psyllium husk
were investigated. The emulsion gel was assessed their utility in meat
puree prepared for people with dysphagia. The results showed that
increasing inulin percentage resulted in reduced particle size and
improved emulsion stability with the optimum at 20% w/w inclusion.
Ultrasonic homogenization further enhanced the emulsion stability by
reducing the size of emulsion droplet and improving encapsulation of
emulsion droplet. Increasing inulin concentrations in the emulsion gels
added into purees also corresponded with decreasing total expressible
fluid (TEF). The stability of puree against the action of
carbohydrate-hydrolyzing enzymes (α-amylase and α-glucosidase) was
improved with the addition of emulsion gels. Therefore, these developed
emulsion gels could be beneficial in formulating modified-texture food
prepare for people with dysphagia.
