Authors: Bhasin Bhavna , Veitla Vineet , Dawson Aprill Z. , Garacci Zhuping , Sturgill Daniel , Ozieh Mukoso N. , Regner Kevin R.
Published: February 2021

Key Points

The rate of AKI is similar in COV-AKI and FLU-AKI, although risk of stage 3 AKI is higher in COV-AKI and is associated with a poorer prognosis.

Black race and mechanical ventilation are associated with a higher risk of COV-AKI. CKD is a major risk factor for AKI in both groups.

COV-AKI is associated with a 2.3-fold higher odds of proteinuria 2+ or more in comparison with FLU-AKI.

Background

Coronavirus disease 2019 (COVID-19) is often compared with seasonal influenza and the two diseases have similarities, including the risk of systemic manifestations such as AKI. The aim of this study was to perform a comparative analysis of the prevalence, risk factors, and outcomes of AKI in patients who were hospitalized with COVID-19 and influenza.

Methods

Retrospective cohort study of patients who were hospitalized with COVID-19 (n=325) or seasonal influenza (n=433). AKI was defined by Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Baseline characteristics and hospitalization data were collected, and multivariable analysis was performed to determine the independent predictors for AKI.

Results

AKI occurred in 33% of COVID-19 hospitalizations (COV-AKI) and 33% of influenza hospitalizations (FLU-AKI). After adjusting for age, sex, and comorbidity count, the risk of stage 3 AKI was significantly higher in COV-AKI (OR, 3.46; 95% CI, 1.63 to 7.37). Pre-existing CKD was associated with a six- to seven-fold increased likelihood for FLU-AKI and COV-AKI. Mechanical ventilation was associated with a higher likelihood of developing AKI in the COVID-19 cohort (OR, 5.85; 95% CI, 2.30 to 15.63). Black race, after adjustment for comorbidities, was an independent risk for COV-AKI.

Conclusions

Pre-existing CKD was a major risk factor for AKI in both cohorts. Black race (independent of comorbidities) and mechanical ventilation were associated with a higher risk of developing COV-AKI, which is characterized by a higher burden of stage 3 AKI and overall poorer prognosis.

Key Points

• Targeting barriers to arteriovenous access through education, needs assessment, peer support, care navigation, and electronic supports was acceptable.

• The program yielded improvements in patient self-efficacy and knowledge, and trends toward improvements in patient and provider confidence.

Background

Guidelines recommend pre-emptive creation of arteriovenous (AV) access. However, <20% of US patients initiate hemodialysis (HD) with a functional AV access. We implemented a quality improvement (QI) program to improve pre-HD vascular access care.

Methods

After conducting qualitative research with key informants, we implemented a 7-month vascular access support QI program at Geisinger Health. The program targeted patient and health system barriers to AV access through education, needs assessment, peer support, care navigation, and electronic supports. We performed pre-, intra-, and postprogram stakeholder interviews to identify program barriers and facilitators and to assess acceptability. In a research substudy, we compared pre- and postprogram self-efficacy, knowledge, and confidence navigating vascular access care.

Results

There were 37 patient and 32 clinician/personnel participants. Of the 37 patients, 34 (92%) completed vascular access–specific education, 33 (89%) underwent needs assessment, eight (22%) engaged with peer mentors, 21 (57%) had vein mapping, 18 (49%) had an initial surgical appointment, 15 (40%) underwent AV access surgery, and six (16%) started HD during the 7-month program. Qualitative findings demonstrated program acceptability to participants and suggested that education provision and emotional barrier identification were important to engaging patients in vascular access care. Research findings showed pre- to postprogram improvements in patient self-efficacy (28.1–30.8, P=0.05) and knowledge (4.9–6.9, P=0.004), and trends toward improvements in confidence among patients (8.0–8.7, P=0.2) and providers (7.5–7.8, P=0.1).

Conclusions

Our intervention targeting patient and health system barriers improved patient vascular access knowledge and self-efficacy.

Triboelectric Nanogenerators and Hybridized Systems for Enabling Next-Generation IoT Applications
Authors: Shi Qiongfeng , Sun Zhongda , Zhang Zixuan , Lee Chengkuo
Published: February 2021

In the past few years, triboelectric nanogenerator-based (TENG-based) hybrid generators and systems have experienced a widespread and flourishing development, ranging among almost every aspect of our lives, e.g., from industry to consumer, outdoor to indoor, and wearable to implantable applications. Although TENG technology has been extensively investigated for mechanical energy harvesting, most developed TENGs still have limitations of small output current, unstable power generation, and low energy utilization rate of multisource energies. To harvest the ubiquitous/coexisted energy forms including mechanical, thermal, and solar energy simultaneously, a promising direction is to integrate TENG with other transducing mechanisms, e.g., electromagnetic generator, piezoelectric nanogenerator, pyroelectric nanogenerator, thermoelectric generator, and solar cell, forming the hybrid generator for synergetic single-source and multisource energy harvesting. The resultant TENG-based hybrid generators utilizing integrated transducing mechanisms are able to compensate for the shortcomings of each mechanism and overcome the above limitations, toward achieving a maximum, reliable, and stable output generation. Hence, in this review, we systematically introduce the key technologies of the TENG-based hybrid generators and hybridized systems, in the aspects of operation principles, structure designs, optimization strategies, power management, and system integration. The recent progress of TENG-based hybrid generators and hybridized systems for the outdoor, indoor, wearable, and implantable applications is also provided. Lastly, we discuss our perspectives on the future development trend of hybrid generators and hybridized systems in environmental monitoring, human activity sensation, human-machine interaction, smart home, healthcare, wearables, implants, robotics, Internet of things (IoT), and many other fields.
Жіночі постаті в «Історії русів»
Authors: Щербак Олена Володимирівна
Published: February 2021

У статті звернена увага на жіночі історичні постаті, згадані в одному з творів української літератури кінця XVIII ст. – «Історії Русів». Хоча концептуально цей твір межує з козацькими літописами, де жінки відігравали другорядну роль, вони займають в «Історії Русів» чільне місце – загалом їх близько двадцяти. Дослідження твору ґрунтується здебільшого на описовому та історичному методах. З’ясовано, що умовно жінок в «Історії русів» можна поділити на три групи. Перша з них, це постаті, відомі ще з «Повісті минулих літ» та з «Густинського літопису». Одних автор тільки згадує, як княгиню Ольгу чи Анну Візантійську, про інших пише детальніше, як про польську королеву Ядвігу чи про Олену Московську, дружину польського короля, яка зберегла вірність православній вірі. Друга група, це історичні персоналії козацької доби, такі як дружина Богдана Хмельницького Мотрона (у тексті Ганна) Чаплинська і Анастасія Маркович, дружина Івана Скоропадського, названа автором «гетьманшею». Сюди ж можна віднести й доволі оригінальну розповідь про таку собі Семіру, дружину турецького паші, яка допомогла звільнити бранців, а потім вийшла заміж за козацького писаря Івана Богуславця. Корені цього сюжету, імовірно, походять від фольклорної легенди про Марусю Богуславку. Третю ж групу складають жінки, які мали стосунок до російської історії – починаючи з Марини Мнішек, дружини Лжедмитрія І, і закінчуючи Катериною ІІ. Особливо багатою виявилася розповідь про сучасне автору події XVIII ст. Однак здебільшого він уникає висловлення власної думки про тодішніх державців, хіба що про Єлизавету Петрівну пише з помітною симпатією за її прихильне ставлення до України. Отже, зроблено висновок, що коло жіночих персонажів «Історії Русів» рідко виходить за межі локальної історії, на відміну від інших барокових літописів. Переважна більшість згаданих у цьому творі жінок не відображувалися у попередніх творах давньої української літератури, а є для неї оригінальними.

Authors: Ponomarev Igor V. , Topchiy Sergey B. , Pushkareva Alexandra E. , Klyuchareva Svetlana V. , Andrusenko Yury N.
Published: February 2021

Introduction: Congenital melanocytic nevus (CMN) is a severe challenge for dermatology. This pigmented skin lesion is undesirable for patients because of its localization in open areas of the body. Various visible and near-infrared laser systems and intense pulsed light (IPL) sources have been applied for CMN treatment. However, post-traumatic hyperpigmentation, structural changes, atrophy, and scarring due to non-specific thermal damage have been observed. Many patients have shown recurrence after treatment. Therefore, it highlights the need for testing new laser modalities for the management of CMN. Methods: Two adult II Fitzpatrick phototype patients (a 55-year-old male and a 30-year-old female) with middle-sized facial CMN (on the forehead and lower eyelid) are presented. All patients were treated with dual-wavelength copper vapor laser (CVL) radiation at 511 nm and 578 nm wavelengths with a power ratio of 3:2. The average power was 0.7-0.85 W with an exposure time of 0.3 seconds. The spot size amounted to 1 mm. Results: Both patients showed complete resolution of CMN after CVL treatments. CMN became crusted within a few days after the laser treatment and peeled off within seven days. No recurrences were observed during the follow-up period up to 24 months. Conclusion: The middle-sized CMN can be successfully treated with dual-wavelength CVL radiation.
Influence of Low-Level Laser Modification and Adhesive Application Mode on the Bonding Efficiency of Universal Adhesives to Er:YAG Laser-Ablated Dentin

Published: February 2021

Introduction: Erbium laser ablation as a method of tooth preparation and conditioning has shown promising results. Although previous studies have adopted various combinations of different laser parameters and several dentin adhesive systems, very few have investigated combining high-level and low-level ER:YAG lasers with Universal adhesives. This study aimed to assess the impact of using low-energy irradiation on the surface micro-topography and shear bond strength (SBS) of universal adhesive (UA) to the erbium:yttrium-aluminum-garnet (Er:YAG) laser-ablated dentin substrate, bonded in etch-and-rinse or self-etch adhesive mode. Methods: Eighty-seven extracted molars were sectioned to expose flat occlusal dentin surface; 60 teeth were divided equally into three groups according to the surface treatment; bur-cutting (B), Er:YAG high-energy laser cutting (L1 - 200 mJ, 20 Hz, 50 μs pulse), or L1 followed by low-energy laser modification (L1 /L2 - 80 mJ, 10 Hz, 50 μs pulse). Then each group was equally divided into two groups (n=10) according to the mode of application of the universal adhesive; either etch-and-rinse (ER) or self-etching (SE). The samples were subjected to thermocycling (5000 cycle between 5°C and 55°C), and SBS was tested. Two-way ANOVA and Tukey post hoc test were used to analyze the results. The remaining 27 samples were used to investigate the effect of the treatment on the topography of the treated dentin surfaces using a scanning electron microscope (SEM). Results: B/SE recorded the highest SBS (25.48 ± 2.6 MPa) followed by B/ER (23.20 ± 6.8 MPa) and L1 /L2 /SE (22.94 ± 4.1 MPa) and with no statistically significant difference between these groups (P >0.05). The lowest SBS results (P<0.05) were recorded for L1/SE (12.22 ± 3 MPa). No statistical differences were found between the SBS of L1 /L2 /ER and L1 /ER groups or between the SBS of L1 /L2 / ER and L1 /L2 /SE groups. Conclusion: A subsequent treatment of the Er:YAG laser-ablated dentin with low-energy laser modification mode (LMM) enhances the SBS of the tested UA when applied in SE mode.

Ban on female migrant workers: Skills-differentiated evidence from Sri Lanka
Authors: Weeraratne Bilesha
Published: February 2021

This study examines the skills-differentiated impact of a restrictive female labour migration policy in Sri Lanka using monthly departure data from 2012 to 2018 in a difference-in-difference model. The policy has resulted in decreasing departures among lower-skilled groups—female domestic, unskilled, semi-skilled, and skilled workers—and increasing departures among middle-level and professional workers. The decrease in departures of lower-skilled groups is consistent with the objectives of the policy and existing impact evaluation studies, while the increase in higher-skilled workers is consistent with the literature on Family Background Report-related corruption and mis-reporting of skills to avoid the policy. Thus, the Family Background Report policy is associated with higher involvement of lower-skilled workers in recruitment-related corruption, higher exposure to recruitment-related vulnerability, and lower foreign employment opportunities. The study also finds that it was appropriate to exempt the 45–49 year age group from the Family Background Report requirement in 2017.
The ecclesiastical reorganisation of space and authority in late antique gaul: Zosimus' letter Multa contra (JK 334 = J3 740)
Authors: Dunn Geoffrey D.
Published: February 2021

On 29 September 417 'Zosimus', bishop of Rome, wrote 'Epistula' 5 ('Multa contra' - JK 334 = J3 740) to the bishops of the Gallic provinces of Viennensis and Narbonensis Secunda. It followed a synod that had been held in Rome on 22 September to consider alleged violations by Proculus of Marseille of the hierarchical relationship between the churches of southern Gaul and the authority of metropolitan bishops over the other churches of their provinces. Episcopal authority was geographically defined and circumscribed by Roman provincial boundaries, with the bishop of a provincial capital having some authority over the other bishops of the province. What was to happen, though, when those boundaries changed or a new city within a province became capital? In a series of four letters (the others being 'Epistulae' 4 ['Cum aduersus' - JK 331 = J3 737], 6 ['Mirati admodum' - JK 332 = J3 738], and 7 [Quid de 'Proculi' - JK 333 = J3 739) written immediately after the synod, of which this letter is the last, Zosimus supported the claims of Patroclus, bishop of Arles, to be not only the metropolitan of Viennensis but, surprisingly, the sole metropolitan over several Roman provinces. This paper examines how authority within the late antique church was dependent upon spatial organisational arrangements and how temporal arguments could be advanced when such spatial arrangements did not suit the personal plans of some ambitious bishops. It further considers the religious conflict that arose over disputed areas of authority and the mechanism by which attempts were made at its resolution and how Zosimus' action contributed ultimately to a developing concept of papal primacy.
The Ottonians turn their Gaze West to the court of al-Andalus
Authors: Nash Penelope
Published: February 2021

The Ottonian dynasty, whose members ruled Germany and northern Italy in the tenth and early eleventh centuries, were not only concerned with their eastern borders and their relations with Byzantium, but also sought news from and alliances with the West. Inhabitants of the Iberian Peninsula informed the ideas of the Ottonian court in a number of ways and contemporaries documented the interactions. Hrotsvitha, a canoness in the Ottonian royal monastery of Gandersheim, recorded the martyrdom of a young Spanish Christian, Pelagius, who met his death at Cordoba in 925. Hrotsvitha wrote that she had come by her account from an eyewitness. John of Gorze performed the office of ambassador for Otto I at the court of the caliph 'Abd al-Rahmān III at Cordoba for three years from 953. Otto sent John to negotiate access to the Alpine passes that were thought to be raided by Andalusians who were located at Fraxinetum and who were controlled by the caliph. Liudprand of Cremona (Ottonian court) and Recemund (court of al-Andalus) were on friendly terms. The Tumbo A at the cathedral of Santiago is a cartulary whose images of royal figures undoubtedly imitate Carolingian or Ottonian models. Little coordinated work has been done on the contacts between the Ottonians and their followers and the dwellers in the Iberian Peninsula. How friendly or hostile were they to each other? What were the physical and temporal barriers to successful contacts? Using texts and visual records, this paper brings to attention the reports of the cultural, economic, social, and political interactions between the Ottonian empire and the court of al-Andalus from their varied points of view.
A Song with “Dash” and “Pep”: A HISTORY OF THE “MARINES’ HYMN” TO 1919
Authors: Bowers Lauren
Published: February 2021

From its unknown nineteenth-century origins, the “Marines’ Hymn” has grown from a collection of unregulated verses into a dignified anthem reflecting the proud history of the Corps. Focusing on the song’s early history until the end of World War I, this article tells the story of that evolution. During this period, the hymn played an increasingly important role in official recruiting and publicity efforts, resulting in a growing popularity among the general public, disagreements about the need to standardize the lyrics, and the introduction of new formats and technologies to allow for wider accessibility. Together, these trends culminated in the authorization and copyright of an official version of the song in the summer of 1919. The “Marines’ Hymn” is known worldwide as a reflection of Marine Corps experiences and values, and this article aims to bring some of its forgotten history and the contributions of its strongest advocates to the attention of a modern audience.

Formation of an effective policy for the repayment of accounts receivable at the enterprise
Authors: Zdrenyk Vasyl
Published: February 2021

Introduction. Trade enterprises in modern conditions have significantly increased the volume of their activities. However, the uncertainty of the external environment and the presence of a number of different problems in the economy as a whole create obstacles to the timely fulfillment of obligations. This necessitates the formation of an effective policy for the repayment of accounts receivable at the enterprise.Objective. The objective of the article is to substantiate the theoretical foundations  and develop practical recommendations for the formation of an effective policy for the repayment of receivables at trade enterprises.Methods. To establish the stages of the formation of the policy of repayment of receivables and its constituent elements, analytical empiricism was used with an orientation to the existing initial conditions and foreign experience. The study used the method of assessment and generalization to develop and substantiate proposals aimed at solving the problem of recognizing receivables as uncollectible, as well as to substantiate the approach to the classification of reserves and the calculation of reserves for doubtful debts.Results. A conceptual approach to the formation of an effective policy for the repayment of accounts receivable from trade enterprises has been formed. The study substantiates that the effective development of a trading enterprise is possible due to the combination of such important components of its activities as a good information base of management and an effective policy for repayment of receivables. The result of the study is also the substantiation of the stages of formation of the policy of repayment of receivables, the development of proposals for its assessment and the formation of reserves for doubtful debts.Discussion. A promising area of further research is the development of methods       of analysis of receivables by actual indicators, the study of opportunities to improve communication and the formation of information support for trade and technological processes based on the use of modern information systems.

In today’s aggressive world there may be a need for a quicker rate of production in agriculture. As we recognize Agriculture is the backbone of India. In India nearly all farmers dealing with issues of a exertions shortage. Day with the aid of using day exertions wages is increasing. In India, the Cotton crop is cultivated in a big amount. After yielding of cotton, the principle trouble face with the aid of using the farmers is to reduce the cotton stalk. Nowadays what farmer did is pluck the cotton stalk manually gather at one place, wait until the stalk receives dry, and after that burn that crop. The downside of burning the crop is, the vitamins which can be released after burning are typically washed away. Soil declines in productiveness after burning. Crop residues last withinside the discipline after the harvest are eliminated with the aid of using burning the stubble or leaving the stalks on the sphere surface, to be mixed with soil both without delay or with the aid of using mechanized chopping. So our purpose is to design and fabrication of the sort of system that can reduce and overwhelmed of cotton stalk. After crushing the overwhelmed crop unfold at the farm. So that this overwhelmed crop is dumped into the soil and it used as natural compost. So the productiveness of soil could be increased,
Interprofessional Showcase

Published: February 2021

Traditional didactic instruction is not an effective means to provide the interprofessional education that health and human services professional students need. This paper describes a college event aimed at engaging undergraduate and graduate students from several academic departments in interprofessional collaboration. Participants toured and interacted in academic spaces of other professional disciplines to gain an understanding of these professional roles. Interprofessional collaboration was demonstrated and experienced in these spaces and in the group discussions that followed these activities. A series of micro-vignettes, questions, and road blocks provided problems for participants to solve in interprofessional groups. Pre-post comparison surveys indicated that participants increased in their understanding of their professional role and the role of others in health care and community settings. An improved understanding of the benefits and challenges of interprofessional teams was achieved and participants felt more confident in their ability to work in these teams at job or internship sites.
Comparison of Two Online Courseware Instructional Methods Using Propensity Score Matching
Authors: Babcock Renée , Georgiou Jean
Published: February 2021

This study used propensity score matching to compare two online courseware systems intended for use as supplements to either face-to-face or online courses. One courseware system focused on adaptive features available to students while completing assignments; whereas the other system was an interactive courseware that provided embedded media supplements and assessments. Participants were students enrolled in a psychology course taught by an instructor who used the adaptive courseware in Fall 2013, switching to the interactive courseware in Fall 2015 and 2016. Propensity score matching was used to match students in 2015 with students in 2013. A separate matching process was done for the 2016 versus 2013 students. The use of propensity score matching was successful in allowing comparison across groups. However, the only consistent finding across the two matched samples was that students appeared to spend less time in the interactive courseware than the adaptive courseware. The most likely reason for the difference is a function of the requirements of the two courseware systems.

CARE HOSPITAL
Authors: Xess Sonali Smita , Anand Vaishali
Published: February 2021

Introduction: Anemia is one of the most commonly diagnosed conditions in a health care set up. Iron deciency anemia is the predominant cause
of anemia across countries and in both sexes (1,2) . Although, in approximately 2 to 4 % of patients, laboratory evidence of macrocytosis is found
(3) .The cause of macrocytic anemia is classied into megaloblastic or non-megaloblastic (4). Common causes of macrocytosis are different by
region and setting. The present study aims at studying patients admitted in Civil Hospital Ahmedabad during the study period with MCV value
more than 100 fL and utilizing the clinical prole and other biochemical parameters to further classify anemia into Megaloblastic and NonMegaloblastic type. The study period is January 1, 2018 to July 31, 2019. Relevant medical Materials and Methods: history of the patients
participating in the study was considered. MCV value was determined from complete hemogram which was performed using Automatic
Hematological Analyser. Peripheral smear examination was done with slides stained in Giemsa stain. Biochemical tests were performed using
Automated Biochemistry Analysers. The data obtained from the above was then utilized in establishing the incidence of various causes of
macrocytic anemia in our study population. Result: Out of the total 325 patients 160 (49%) were found to have megaloblastic anemia and 128
patients (40%) were found to have non-megaloblastic anemia. In the remaining 37 (11%) patients, no cause of macrocytosis was identied. The
etiologies of macrocytic anemia identied in the present study were Vitamin B12 deciency, hepatic dysfunction, hypothyroidism, renal
dysfunction and accelerated erythropoiesis (due to hemolysis or blood loss). Conclusion: The most common cause of macrocytic anemia in our
study population was found to be Megaloblastic anemia.

Published: February 2021

Amaurosis after inferior alveolar nerve anesthesia is characterized by partial or complete loss of vision, especially without an externally perceptible change in the eye. This case reports a unilateral transient ocular complication after an inferior alveolar nerve block. A 34-year-old female patient was administered a left inferior alveolar nerve block for root canal treatment of tooth #36. Few minutes later patient reported partial loss of vision followed by complete loss of vision from her left eye. Patient completely recovered after 30 minutes. Amaurosis is an unusual ocular complication which can be distressing to both the patient and the clinician. Ocular complications after inferior alveolar nerve block are rare but can still occur. The clinician should be aware of the proper anatomical landmarks before administration of local anesthesia. The clinician should have adequate knowledge about the regional anatomy and can try to minimize the potential for such complications through effective management.

Relevance. Around the world, there is an increase in the number of patients with chronic kidney disease, which some authors regard as a pandemic. The Aim of the work is an epidemiological assessment of medical losses by the class of the genitourinary system in the regions of Kazakhstan. Materials and methods. The YLL indicator was calculated according to a standardized methodology. The study period was 10 years (2008-2017). Medical and social losses were calculated as the share of losses of gross regional product from premature mortality of the working-age population due to diseases of the genitourinary system. Results and Conclusions. The incidence by the class of the genitourinary system in Kazakhstan has zoning by region and a tendency to chronicity, especially in the central part of the Republic of Kazakhstan. There is an increase in mortality due to disease. In the group of men for the study period, the average age of the deceased was 65.2 years, for women – 68 years. The maximum cumulative losses over 10 years in absolute terms were found in the working-age population of 45-59 years. Medical and social losses from diseases of the genitourinary system in relation to the gross domestic product averaged 0.16%. Direct losses increased by 4.6 times over the study period.

Aim. To access overall and event-free survival rates in patients after surgical treatment of localized and locally spread pancreatic head cancer. Materials and methods. A single center observational trial was conducted at a low-volume pancreatic surgery center in Khanty-Mansiysk. Data were collected retrospectively from 2007 to 2019. Patients with resectable tumors were included into the study whose final histology showed pancreatic ductal adenocarcinoma and en-bloc resection. According to the technical facilities and actual clinical protocols all patients received surgical treatment only and were then monitored. Data on progression patterns and survival rates were collected and calculated using Kaplan-Meier survival analysis. Results. Median overall survival (OS) after R0 pancreaticoduodenectomy was 16,8 months (IQR 10,9-23,5). Median progression-free survival was 10,6 mo. (IQR 8,0-20,7). OS in jaundiced patients was 4,9 mo. shorter than in patients without jaundice at the diagnosis (р = 0,011). Patients with serum bilirubin level < 100 μmol/l lived on average 7.2 months longer (p = 0.014). Most frequent sites of primary progression were liver and peritoneum, lungs, bones, lymph nodes of the abdominal cavity / retroperitoneal space, less often metastases were found in the skin and soft tissues. In 21.4% of cases metastases were found in several organs simultaneously with most frequent combination of liver and peritoneum, liver and lungs, lungs and bones. The median survival after progression was 7.1 ± 4.8 months Conclusion. Pancreatic duct adenocarcinoma has a high potential for progression and has therefore poor prognosis. To improve long-term outcomes, it is advisable to apply additional therapeutic options perioperatively.

Aim. Conduct a correlation analysis of the dependence of risk factors in the etiopathogenesis of chronic venous diseases. Materials and methods. On the basis of the GBUZ TO “Maternity Hospital № 2” of the city of Tyumen, an analysis of the patients’ data was carried out in the form of a clinical examination and questionnaires. The average age of the examined patients is 26 years. The survey involved 468 women in the period 2017-2019. Results. Among the surveyed patients, 52,4% had CVD. Pregnant women with CVD have subjective symptoms and objective symptoms. Dilated veins exist for less than 5 years in 86,5% of pregnant women, and in 13,5% – for more than 5 years. Varicose veins, with a predominant localization on the left lower limb, were found in 7,5%, on the right – in 11,1%, and on both legs – 81,5%. Conclusion. The use of a statistical indicator made it possible to calculate the dependence of the appearance of a disease in the presence of a certain risk factor – in this case, the correlation is direct, the relationship is close (0,94); as well as to evaluate the prognosis for pregnant women prospectively and create complexes of measures to prevent venous diseases, taking into account the individual characteristics of patients.
