Authors: Zanza Christian , Longhitano Yaroslava , Leo Mirco , Romenskaya Tatsiana , Franceschi Francesco , Piccioni Andrea , Pabon Ingrid M. , Santarelli Maria T. , Racca Fabrizio
Published: August 2021

Background:

During general anesthesia, mechanical ventilation can cause pulmonary
damage through mechanism of ventilator-induced lung injury, which is a major cause of post-operative
pulmonary complications, which varies between 5 and 33% and increases the 30-day mortality
of the surgical patient significantly.

Objective:

The aim of this review is to analyze different variables which played a key role in the
safe application of mechanical ventilation in the operating room and emergency setting.

Method:

Also, we wanted to analyze different types of the population that underwent intraoperative
mechanical ventilation like obese patients, pediatric and adult population and different strategies
such as one lung ventilation and ventilation in trendelemburg position. The peer-reviewed articles
analyzed were selected according to PRISMA (Preferred Reporting Items for Systematic reviews
and Meta-Analyses) from Pubmed/Medline, Ovid/Wiley and Cochrane Library, combining
key terms such as: “pulmonary post-operative complications”, “protective ventilation”, “alveolar recruitment
maneuvers”, “respiratory compliance”, “intraoperative paediatric ventilation”, “best
peep”, “types of ventilation”. Among the 230 papers identified, 150 articles were selected, after title
- abstract examination and removing the duplicates, resulting in 94 articles related to mechanical
ventilation in operating room and emergency setting that were analyzed.

Results:

Careful preoperative patient’s evaluation and protective ventilation (i.e., use of low tidal
volumes, adequate PEEP and alveolar recruitment maneuvers) has been shown to be effective not
only in limiting alveolar de-recruitment, alveolar overdistension and lung damage, but also in reducing
the onset of Pulmonary Post-operative Complications (PPCs).

Conclusion:

Mechanical ventilation is like “Janus Bi-front” because it is essential for surgical procedures,
for the care of critical care patients and in life-threatening conditions, but it can be harmful
to the patient if continued for a long time and where an excessive dose of oxygen is administered
into the lungs. Low tidal volume is associated with a minor rate of PPCs and other complications
and every complication can increase the length of Stay, adding cost to NHS between 1580 €
and 1650 € per day in Europe and currently the prevention of PPCS is the only weapon that we possess.

induced Diabetic Rats
Authors: Azzane Amine , Amssayef Ayoub , Eddouks Mohamed
Published: August 2021

Aims:

The aim of the study was to evaluate the antihyperglycemic effect of Chenopodium
quinoa.

Background:

Chenopodium quinoa is a pseudocereal plant with several medicinal properties.

Objective:

The goal of this investigation was to determine the antihyperglycemic activity of
Chenopodium quinoa in both normal and streptozotocin (STZ)-induced diabetic rats.

Methods:

In this study, the effect of the aqueous extract of Chenopodium quinoa seeds (AECQS)
(60 mg/kg) on blood glucose levels was evaluated in both normal and diabetic rats after a single (6
hours) and repeated oral administration (7 days of treatment). The effect of this herb on glucose tolerance
and lipid profile was also studied. Additionally, histopathological examination of the liver
was carried out using the Hematoxylin-Eosin method. Furthermore, the in vitro antioxidant activity
as well as, preliminary phytochemical screening and quantification of some secondary metabolites
(phenolic compounds, flavonoids and tannins) were performed according to standard methods.

Results:

AECQS produced a significant lowering effect on plasma glucose levels in STZ-induced
diabetic rats. In addition, this extract exhibited a remarkable amelioration on hepatic histopathology
in diabetic rats. In addition, the extract exerted a remarkable antioxidant activity which could be
due to the presence of some compounds found in this herb.

Conclusion:

In conclusion, this study demonstrates that the aqueous extract of Chenopodium quinoa
seeds has a favorable effect in controlling diabetes mellitus.

Authors: Raghu T.R. , Raj V.A. Sathwik , Kharge J. , Setty H.S. Natraj , Patil Rahul S. , Manjunath C.N.
Published: August 2021

Objective:

To assess the safety and efficacy of Novel tapered (BioMime™ Morph) sirolimus-
eluting stent (SES) for left main PCI in a real-world scenario.

Background:

Currently, no data is available on clinical usefulness of tapered ultrathin stents in left
main PCI.

Methods:

This was a prospective, non-randomised, single centre study carried out between February
2018 and May 2020 at a tertiary cardiac care centre in southern India. The study included patients
treated with BioMime Morph tapered stent for distal de novo LMB lesion or ostial LAD/LCX
lesions with significant size disparity between reference segments based on the eligibility criteria.
Primary endpoint of the study was the cumulative incidence of major adverse cardiovascular
events (MACE) composed of cardiac death, myocardial infarction, and clinically driven target-lesion
revascularisation at follow-up.

Results:

A total of 41 patients (average age of 54.83±9.81 years) were included in the study. Average
SS-2 score was 23.17±5.42. Majority of the lesions (n=31; 75.61%) were of medina class
(0.1.0). Provisional single stent strategy was adopted for treatment of LMB lesions. TIMI flow-3
was achieved in 40 patients (97.56%). Median clinical follow-up was 20 months (range 6-34
months). There was no periprocedural complication or MACE during follow-up.

Conclusion:

Tapered stents may be an acceptable alternative for LM intervention in an anatomical
subset of patients with tapered vessels.
Can a ‘3-tier Screening’ Strategy be Adopted during COVID-19 Pandemic for Safer Air Travel and to Help Curb its Spread Across Borders?
Authors: Shahid Mohammad
Published: August 2021

Since the appearance of SARS-CoV-2 in 2019, it spread quickly crossing geographical borders and thus affected almost the entire world. It was alarming to note its quick spread, which obviously was due to the increased frequency and ease of air travel in this era. Currently, many airlines (and countries too) have a prerequisite to have a negative COVID-19 RT-PCR test within 72 hrs. prior to boarding the flight. Although all the necessary precautions are strictly enforced during air travel, there is still a possibility that a person with a negative COVID-19 test (RT-PCR) around 72hrs prior to boarding the flight would have an infection and that the person would pass it on to fellow passengers on board and thus can further spread SARS-CoV-2 infection into the community if robust action is not initiated. There is also a subconscious apprehension among the passengers that co-passengers may have an infection on board. This is especially worrisome seeing the appearance of new variants recently. Here I present the logistics for a ‘3-tier screening’ protocol (1st test by RT-PCR within 72hrs of the flight schedule, 2nd test by rapid antigen detection method 1-5hrs prior to flight schedule, 3rd test post-arrival or to follow the destination country post-arrival protocol), which would at least provide an extra filter to separate the recently identified positive cases and thus prevent the spread of this threatening disease across the borders.

Aspectos ambientales y culturales de los nodos panbiogeográficos prioritarios para mamíferos terrestres del centro-sur de México
Authors: Corona-Mendoza Willie , Escalante Tania
Published: August 2021

Los Nodos Panbiogeográficos (NP) constituyen uno de los principales aportes de la biogeografía evolutiva a la conservación de la biodiversidad, los cuales se interpretan como la superposición en espacio-tiempo de diferentes fragmentos geobióticos ancestrales, permitiendo identificar prioridades que preservan la riqueza de especies y de orígenes evolutivos. Por otro lado, los mamíferos son un grupo con una importante connotación cultural en las regiones indígenas de México, donde son utilizados principalmente como alimento y medicina. Dado que México es uno de los países con una correlación estrecha entre su gran diversidad biológica y cultural, el objetivo de esta investigación se centró en la priorización y caracterización ambiental y cultural de NP para la conservación de mamíferos en el centro-sur de México. La priorización de la riqueza de especies de los NP se realizó empleando tres criterios, y los NP Prioritarios (NPP) fueron caracterizados ambiental y culturalmente. A partir de siete grupos de NP integrados por 31 NP y 3 NP que no pertenecieron a ningún grupo, se priorizaron 23 NP. La mayoría de los NPP se localizó sobre la provincia biogeográfica de las Tierras Altas de Chiapas, seguida por la Sierra Madre del Sur, mientras que la Faja Volcánica Transmexicana tuvo el menor número de NPP. En las dos primeras provincias hubo superposición y aglomeración de NPP, específicamente sobre los Altos de Chiapas y la Sierra Juárez. Estos dos sitios parecen ser las áreas geográficas más complejas desde el punto de vista biogeográfico-evolutivo, físico-geográfico y cultural. En términos de conservación, al conservar los NPP, también se protegerá gran cantidad de recursos naturales y culturales.

Authors: Wee Priscilla Jia Ling , Kwan Yu Heng , Loh Dionne Hui Fang , Phang Jie Kie , Puar Troy H , Østbye Truls , Thumboo Julian , Yoon Sungwon , Low Lian Leng
Published: August 2021

Background

The management of diabetes is complex. There is growing recognition of the use of patient-reported outcome measures (PROMs) as a standardized method of obtaining an outlook on patients’ functional status and well-being. However, no systematic reviews have summarized the studies that investigate the measurement properties of diabetes PROMs.

Objective

Our aims were to conduct a systematic review of studies investigating the measurement properties of diabetes PROMs by evaluating the methodological quality and overall level of evidence of these PROMs and to categorize them based on the outcome measures assessed.

Methods

This study was guided by the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. Relevant articles were retrieved from the Embase, PubMed, and PsychINFO databases. The PROMs were evaluated with the COSMIN (COnsensus-based Standards for the selection of health Measurement Instruments) guidelines.

Results

A total of 363 articles evaluating the measurement properties of PROMs for diabetes in the adult population were identified, of which 238 unique PROMs from 248 studies reported in 209 articles were validated in the type 2 diabetes population. PROMs with at least a moderate level of evidence for ≥5 of 9 measurement properties include the Chinese version of the Personal Diabetes Questionnaire (C-PDQ), Diabetes Self-Management Instrument Short Form (DSMI-20), and Insulin Treatment Appraisal Scale in Hong Kong primary care patients (C-ITAS-HK), of which the C-PDQ has a “sufficient (+)” rating for >4 measurement properties. A total of 43 PROMs meet the COSMIN guidelines for recommendation for use.

Conclusions

This study identified and synthesized evidence for the measurement properties of 238 unique PROMs for patients with type 2 diabetes and categorized the PROMs according to their outcome measures. These findings may assist clinicians and researchers in selecting appropriate high-quality PROMs for clinical practice and research.

Authors: Albers Eline , Nijhof Linde N , Berkelbach van der Sprenkel Emma E , van de Putte Elise M , Nijhof Sanne L , Knoop Hans
Published: August 2021

BACKGROUND

Internet-based cognitive behavior therapy (I-CBT) for adolescents with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) has been shown to be effective in a randomized controlled trial (RCT; Fatigue in Teenagers on the Internet [FITNET]). FITNET can cause a significant reduction in fatigue and disability.

OBJECTIVE

We aimed to investigate whether FITNET treatment implemented in routine clinical care (IMP-FITNET) was as effective, using the outcomes of the FITNET RCT as the benchmark.

METHODS

Outcomes of CFS/ME adolescents who started IMP-FITNET between October 2012 and March 2018 as part of routine clinical care were compared to the outcomes in the FITNET RCT. The primary outcome was fatigue severity assessed posttreatment. The secondary outcomes were self-reported physical functioning, school attendance, and recovery rates. Clinically relevant deterioration was assessed posttreatment, and for this outcome, a face-to-face CBT trial was used as the benchmark. The attitude of therapists toward the usability of IMP-FITNET was assessed through semistructured interviews. The number of face-to-face consultations during IMP-FITNET was registered.

RESULTS

Of the 384 referred adolescents with CFS/ME, 244 (63.5%) started IMP-FITNET, 84 (21.9%) started face-to-face CBT, and 56 (14.6%) were not eligible for CBT. Posttreatment scores for fatigue severity (mean 26.0, SD 13.8), physical functioning (mean 88.2, SD 15.0), and full school attendance (mean 84.3, SD 26.5) fell within the 95% CIs of the FITNET RCT. Deterioration of fatigue and physical functioning after IMP-FITNET was observed at rates of 1.2% (n=3) and 4.1% (n=10), respectively, which is comparable to a waiting list condition (fatigue: 1.2% vs 5.7%, χ21=3.5, P=.06; physical functioning: 4.1% vs 11.4%, χ21=3.3, P=.07). Moreover, 41 (16.8%) IMP-FITNET patients made use of face-to-face consultations.

CONCLUSIONS

IMP-FITNET is an effective and safe treatment for adolescents with CFS/ME in routine clinical care.

Published: August 2021

BACKGROUND

A vision center (VC) is a significant eye care service model to strengthen primary eye care services. VCs have been set up at the block level, covering a population of 150,000-250,000 in rural areas in North India. Inadequate use by rural communities is a major challenge to sustainability of these VCs. This not only reduces the community’s vision improvement potential but also impacts self-sustainability and limits expansion of services in rural areas. The current literature reports a lack of awareness regarding eye diseases and the need for care, social stigmas, low priority being given to eye problems, prevailing gender discrimination, cost, and dependence on caregivers as factors preventing the use of primary eye care.

OBJECTIVE

Our organization is planning an awareness-cum-engagement intervention—door-to-door basic eye checkup and visual acuity screening in VCs coverage areas—to connect with the community and improve the rational use of VCs.

METHODS

In this randomized, parallel-group experimental study, we will select 2 VCs each for the intervention arm and the control arm from among poor, low-performing VCs (ie, walk-in of ≤10 patients/day) in our 2 operational regions (Vrindavan, Mathura District, and Mohammadi, Kheri District) of Uttar Pradesh. Intervention will include door-to-door screening and awareness generation in 8-12 villages surrounding the VCs, and control VCs will follow existing practices of awareness generation through community activities and health talks. Data will be collected from each VC for 4 months of intervention. Primary outcomes will be an increase in the number of walk-in patients, spectacle advise and uptake, referral and uptake for cataract and specialty surgery, and operational expenses. Secondary outcomes will be uptake of refraction correction and referrals for cataract and other eye conditions. Differences in the number of walk-in patients, referrals, uptake of services, and cost involved will be analyzed.

RESULTS

Background work involved planning of interventions and selection of VCs has been completed. Participant recruitment has begun and is currently in progress.

CONCLUSIONS

Through this study, we will analyze whether our door-to-door intervention is effective in increasing the number of visits to a VC and, thus, overall sustainability. We will also study the cost-effectiveness of this intervention to recommend its scalability.

Authors: Kim KangHyun , Kim Sung Min , Park YoungMin , Lee EunSol , Jung SungJae , Kang Jeongyong , An DongUk , Min Kyungil , Yu Hyeong Won , Han Hyun Wook
Published: August 2021

BACKGROUND

A large amount of healthcare data has been produced and accumulated in recent years: big data derived from hospital records, patient medical records, medical examinations, and other sources. These data require proper management and analysis to derive meaningful results to improve healthcare. For proper management, the data must be integrated, secured, and made interoperable between individuals, hospitals, and companies, while protecting patient privacy.

OBJECTIVE

The purpose of this research was to create a healthcare data marketplace using a blockchain-based business-to-consumer model that ensured the integration, security, and interoperability of healthcare data between individuals, hospitals, companies, and marketplaces. This marketplace should enable direct transactions of healthcare data between companies that need individual healthcare data and individuals who own the data.

METHODS

To investigate the essential elements of a healthcare data marketplace, we considered two aspects: technology and service. A healthcare data marketplace was created using MySQL 8.0, JavaScript library, and Node.js software. The marketplace system featured security of data, access for companies and individuals, and a data transaction monitor. Furthermore, anonymization and standardization of data were implemented. A web-based application was developed for implementation of the marketplace system, along with a mobile application system for use by individuals.
Finally, we evaluated the performance of the data marketplace system in three scenarios: male and obese (BMI ≥30 kg/m2); male aged ≥40 years with abnormal liver function tests (aspartate aminotransferase ≥40 units/L and alanine aminotransferase ≥40 units/L); and female aged ≥60 years with high blood pressure (systolic pressure ≥130 mmHg and diastolic pressure ≥90 mmHg).

RESULTS

A web-based application was developed to implement the healthcare data marketplace; a mobile application was also developed for individuals who provide their healthcare data. The performance of the data marketplace was evaluated through the three scenarios by calculating the time taken for completion of each scenario. A data query was executed fully within about 1–2 s; approximately 9.5 healthcare data queries were processed per minute in each scenario.

CONCLUSIONS

We successfully created a prototype of a healthcare data marketplace that ensured the integrity and security of data through its honest broker design.

Authors: Shubina Ivanna
Published: August 2021

BACKGROUND

Interactive mobile technologies (IMB) are viewed as a promising opportunity to provide support in treatment for patients’ with eating disorders. The authors analyzed papers to find out the patterns of research domains in cognitive-behavioral therapy using interactive mobile technologies and eating disorder treatments. The development of interactive mobile technologies in eating disorder treatments was enhanced significantly during the last decade. Therefore this emerging research field has been found interesting and attractive to keep it in the research agenda. Consequently, the author planned various research settings for current and further studies.

OBJECTIVE

This research aims to explore the scientific patterns of interactive mobile technologies for cognitive-behavioral treatment for individuals with eating disorders in scholarly publications and analyze the findings to suggest further studies in an emerging research field.

METHODS

The bibliometric analysis employed such as identifying publication patterns, most important keywords, and trends for the subjects and fields for the period of the last decade (2010 to 2021). In this study, research questions were formed based on the relevant literature. The author concentrated on highly ranked sources, the data retrieved from the known databases, and the study conducted with the proven bibliometric approach,

RESULTS

A total of 875 studies were found concerning the research domains and retrieved from the LENS database. The vast majority of the papers were written in the English language by 100 authors/co-authors from 70 different countries, leading with the United Kingdom, then followed by the USA, Australia, Spain, Germany and Sweden. Descriptive characteristics The vast majority of the papers were written in the English language by 100 authors/co-authors from 70 different countries, leading with the United Kingdom, then followed by the USA, Australia, Spain, Germany and Sweden.

CONCLUSIONS

The research revealed that, although the early years of publication record shown as low, recent years (from 2016) represent an overall increase in research domains. The main contribution of the findings indicates that IBM, in combination with in-person cognitive-behavioral therapy for eating disorders, increases the efficiency of health intervention, including reducing essential symptoms and improving life quality. Besides, IBM can be used as a supportive tool in managing diet, body dissatisfaction, stress, and sleep disturbance. This paper would be useful for researchers to obtain an overview of the publication trends on research domains to be concerned for further studies and shows the potential gaps in those fields.

The results of calibrating satellite altimetry measurements from the space geodetic system “GEO-IK-2” in the water area of the Rybinsk reservoir
Authors: Gusev I.V. , Dargel E.V. , Langeman I.P. , Lebedev S.A.
Published: August 2021

The authors present the results of satellite altimetry measurements calibration from the space geodetic system “GEO-IK-2” in the water area of the Rybinsk reservoir, obtained through two independent methods. In the first case, the altimetry measurements were calibrated by comparing the sea surface heights with respect to the reference ellipsoid, which were calculated from radio altimeter measurements, and from the processing of ground GNSS measurements performed at the sub-satellite point at the time of passing the GEO-IK-2 spacecraft. For this, in the summer of 2020, special geodetic measurements were carried out in the water area of the Rybinsk reservoir. The GNSS receiver was mounted on the Sea Buoy, which was towed by boat to the specified sub-satellite points, the coordinates of which were predetermined from the forecast of satellite orbits. At the same time, base stations for GNSS observations were installed on the coast. The largest difference in the sea surface height does not exceed 13,9 cm. The second method is cross-calibration by radio altimeter measurements from other altimetry spacecraft. In this case, the tracks of the first and second satellites within a relatively short time interval cross one common point, at which the sea surface height is determined. For this, the Jason-3 spacecraft was selected, the track of which was crossed by the GEO-IK-2 vehicle track on September 11, 2020 over the water area of the Rybinsk Reservoir. The difference in sea surface heights was 9,6 cm.
Application of computer technologies and their potential to develop geophysical mapping
Authors: Loginov D.S.
Published: August 2021

The author describes four main work directions of creating geophysical maps using modern software, represented by specialized systems (SSS) and geographic information ones (GIS). The technological features of data processing practice stages and creating geophysical fields’ digital models, the compilation and designing geophysical maps’ thematic content as results of geological and geophysical works are considered. The main tasks of combined use of GIS and SSS tools were identified. To overcome these shortcomings, additional tools were developed for ArcGIS, as the leading system in the oil and gas industry. They ensure the preservation of design parameters for color scales adopted in the SSS; automatic calculation of the labels’ rotation angle to the objects of point localization; maintaining the layer structure of map projects at exporting to publishing program formats. The solutions considered in the article can be applied for compilation and design of isoline maps in some other areas of thematic cartography, and can also contribute to improving the cartographic component of domestic geological and geophysical software products and geographic information systems.

Autonomiczne pojazdy ciężarowe w tym platooning, pomimo że jest już od kilku lat testowany w Europie, wciąż jest mało rozpoznawalny w Polsce. Możliwość zastosowania nowych rozwiązań w kraju wiąże się w pierwszej kolejności z wiedzą na ich temat wśród podmiotów sektora TSL. W artykule zaprezentowano wyniki badań ankietowych przeprowadzonych wśród osób pracujących w sektorze TSL, których celem było określenie poziomu ich wiedzy na temat ciężarowych pojazdów autonomicznych, ocena możliwości testowania systemu platooning na terytorium Polski oraz wskazanie zalet i wad wdrożenia tego typu rozwiązania w kraju.
Bezpieczeństwo zarządzania łańcuchem dostaw biomasy
Authors: Krupnik Dorota
Published: August 2021

Celem niniejszego artykułu jest zaprezentowanie możliwości wykorzystania biomasy do celów energetycznych oraz analiza bezpiecznego zarządzania procesami logistycznymi w łańcuchu dostaw biomasy. Czynnikami, które należy wziąć pod uwagę w bezpiecznym zarządzaniu łańcuchem dostaw biomasy, są m.in.: różnorodność biomasy (objętość, wilgotność, rozproszony charakter), odległości od źródeł pozyskania surowców, lokalizacja miejsc produkcji energii. W celu uniknięcia przemieszczania dużych mas biomasy na znaczne odległości zasadne jest tworzenie lokalnych rynków biomasy oraz systemów logistycznych minimalizujących koszty pozyskiwania, transportu i składowania biomasy. Dużą nadzieję można wiązać z certyfikowanymi systemami zapewniania jakości biomasy. Wpłynie to w znacznym stopniu na bezpieczeństwo dostaw tak różnorodnego w swoim właściwościach surowca.
Rozwój i konkurencyjność transportu towarów koleją w Polsce
Authors: Rabe Marcin
Published: August 2021

Infrastruktura jest jednym z dwunastu filarów konkurencyjności gospodarek. Infrastruktura kolejowa jako jeden z zasadniczych podstaw konkurencyjności jest swoistego rodzaju kręgosłupem gospodarki, dlatego jest tak ważna dla zapewnienia efektywnego funkcjonowania i rozwoju gospodarki. Celem opracowania jest ukazanie barier rozwoju transportu towarów koleją w Polsce. W artykule przedstawiono stan transportu kolejowego w Polsce oraz analizę założeń Projektu Strategii Zrównoważonego Rozwoju Transportu do 2030 roku. Projekt ten zakłada w latach 2015–2030 wzrost transportu drogowego minimum o 196 mln t, a wzrost transportu kolejowego minimum o 30 mln t, czyli o 6,5 razy mniej niż transport samochodowy. Wyniki badań w opracowaniu przedstawione zostały metodą opisową wspartą tabelaryczną prezentacją danych. Zrównoważenie kosztów infrastruktury kolejowej z infrastrukturą samochodową jedynie w niedużym stopniu może poprawić rozwój i konkurencyjność kolei. Nieodzowne jest więc podjęcie takich działań niezwiązanych z opłatami w transporcie kolejowym, które poprawią konkurencyjność transportu kolejowego względem transportu samochodowego.
Distribution channels used by fruit and vegetables producer organizations in Poland
Authors: Chlebicka Aleksandra
Published: August 2021

Fruit and vegetable production is an important branch of Polish agriculture. In recent years, the fruit and vegetable market has undergone significant changes concerning in particular the structure of the distribution channels. Growers establish producer organizations (PO’s) to increase their bargaining position vis a vis large retail chains and processing companies. Knowledge on the way producer organizations operate on the market is limited. Firstly, the aim of the study is to fill this gap, first of all, by indicating the distribution channels used by PO’s in Poland. Secondly, an attempt was made to answer the question whether producer organizations supplying retail chains differ from other entities. The study showed that PO’s used various distribution channels. The most important ones were wholesale markets, retail chains (super and hypermarkets, discount chains) and processing companies. It turned out that PO’s selling to retail chains were relatively larger in terms of the value of produce delivered by producers-members and more prone to source fruit and vegetables from farmers who are not their members. The study was conducted using unpublished governmental data on the population of PO’s active in the fruit and vegetable sector in Poland in 2017.

Authors: Jałowiecki Piotr
Published: August 2021

The paper presents the results of research on the relationship between the level of advancement of technology, solutions and logistics systems used in the Polish food sector, and the size of employment, scale of investment, financial situation and position on the market of food enterprises. Several different dependency assessment methods were used and compared in the study. The research falls within the broader thematic area of Solow’s productivity paradox in its extended understanding of logistics systems [Jałowiecki 2018]. The results obtained seem to correspond to one of the most frequently raised reasons for the occurrence of this paradox related to statistical methods. The main purpose of the research, the results of which were presented in the work, was to construct a synthetic indicator to assess the level of sophistication of logistic solutions used and to use it in the research of the food sector.

Authors: Jezierski Andrzej
Published: August 2021

The higher and higher level of competitiveness of enterprises, the increasing expectations of customers or internalization of business are just a few examples of challenges that most of companies must face nowadays. None of these challenges may be faced, however, if the companies do not cope with logistics problems. The increasing number of problems, among others related to the necessity of diversification of products, of provision of frequent, fast and small deliveries, of ensuring reliability and flexibility in operation, of transfer of goods almost all over the world, can no longer be solved with application of traditional methods. Condition of success in contemporary logistics is implementation of modern technology. Companies without IT systems, without automatic identification of goods or electronic exchange of data have not chances for strong presence in today’s supply chains or other modern forms of business. In this paper characteristics of selected information and communication technologies (ICT) were presented with reference to the operation of contemporary logistics systems. The introduction presents the role and substance of the information resources in logistics. Technological solutions concerning transfer of information were grouped and characterized according to the following types: family of electronic connections, corporate networks and information highways. In each group of the solutions main faults and benefits were presented, from the perspective of possibilities of application in logistics.

Published: August 2021

The study deals with economic and logistical conditions for the obtaining and use of various energy sources in the world. The first part presents the importance of energy in periods of human activity on Earth, from the time of gathering and hunting to modern times. It was pointed out how energy sources evolved based on successive innovations and inventions during subsequent periods of human development. The article presents the importance of individual energy sources in the modern world, indicating their logistical susceptibility in the field of extraction, storage and distribution. The length of periods of availability of non-renewable energy resources having the attribute of depletion was indicated using the Raw Materials Availability Index (RMAI). An analysis was made of the locations of individual energy resource deposits, stating that only a few countries have over 80% of global reserves, which means that other countries and societies depend on raw material monopolists.

Published: August 2021

Identification of specific risk factors for severe coronavirus disease 2019 (COVID-19) is crucial for prevention of poor outcomes and mortality. This retrospective cohort study of patients hospitalized with COVID-19 demonstrated that older age, male sex, Black race, diabetes, elevated BMI, and elevated inflammatory markers were correlated with critical illness in COVID-19. Older age, male sex, diabetes, and inflammatory markers, but not elevated BMI, were associated with mortality. Despite having greater odds of critical illness, Black patients had lower odds of death than White patients. Older age, male sex, diabetes, and elevated inflammatory markers were significantly associated with venous thromboembolism. These findings suggest a need to aggressively identify and manage modifiable risk factors (i.e., diabetes and elevated BMI) and encourage vaccination of at-risk individuals to prevent poor outcomes from COVID-19.
