SPLENECTOMY IN PATIENTS WITH PATHOLOGY OF THE BLOOD SYSTEM
Authors: Bichkov S. O. , Dushyk L. M. , Cherkova N. V. 
Published: October 2022

Abstract. Splenectomy (SE) in hematologic patients is accompanied by an increased risk due to the presence of a hemostasis violation in most cases. All this determines the search for more favorable methods of surgical intervention in patients with diseases of the blood system. The purpose of the study is to improve the results of surgical treatment of patients with blood system diseases by planning the method of splenectomy.
Materials and methods: the work was performed on the basis of a comprehensive clinical-laboratory and instrumental examination of 112 patients with various diseases of the blood system that needed surgical treatment. In addition to laboratory diagnosis, special attention was given to the anamnesis: duration of the disease, hormonal therapy; instrumental research methods: ultrasound of the abdominal cavity and CT, as well as nosologies. A harmonic scalpel was used to mobilize the spleen. The EndoGIA-30 stapler (AutoSuture) was used to treat the vascular pedicle.
Results and discussion: analysis of the results of SE in patients with hematological profile showed that the choice of surgical access depends on many factors which can be set before operation by dint of ultrasound and CT. There were no conversion cases, which could be explained by the possibility of objective preoperative planning, as a result of which in cases of laparoscopic adverse events, a decision was made to perform open type of SE. The absence of complications and fatal cases at SE in hematologic patients shows the efficacy of the use of harmonic scalpel and EndoGIA-30 (AutoSuture) staplers to mobilize the spleen.
Conclusions: the use of ultrasound and CT plays an important role in planning the method of spleenectomy, which avoids cases of conversion. Simultaneous use of harmonic scalpel and Autosuture staplers for performing SE helps to avoid complications.

Abstract. The purpose of the study: to study and evaluate the results of surgical treatment of acute adhesive obstruction of the small intestine.
Material and methods. Of the 49 patients with acute adhesive small intestine obstruction in the past, 83,7 % underwent 1 operation, 14,3 % — 2.
Results and discussion. After laparotomy, 75,5 % of patients crossed adhesions, 4,1 % had small bowel + bicuspid end ileostomy, 18,4 % had small bowel resection, 2 % had ileotransversoanastomosis, and 18,4 % had simultaneous surgery. Intubation of the small intestine according to the indications.
Iatrogenic injuries occurred in 12,2 % of patients, postoperative complications - in 18,4 %. 3 (6,1 %) patients died: sepsis (1), multiple organ failure (1), COVID-19 associated pneumonia (1).
Conclusions. Acute adhesive obstruction of the small intestine is 3,8 % of all acute surgical diseases of the abdominal cavity. The scope of the operation depended on the viability of the small intestine, the possibility of separation of the conglomerate or infiltrate, the choice of method of incubation of the intestine, the presence of simultaneous pathology. This surgical tactic led to 18,4 % of postoperative complications, 4,1 % — relaparotomies, 6,1 % — mortality.

Summary. The development of new technological solutions for palliative surgical treatment of patients with unresectable pancreatic cancer is relevant because the frequency of postoperative complications in such patients reaches 25 % and mortality — 20 %.
Objective. Improve the diagnosis and immediate results of palliative surgical treatment of patients with unresectable pancreatic cancer complicated by mechanical jaundice and duodenal obstruction.
Materials and methods. A comparative analysis of the results of surgical treatment of two groups of patients (11 patients in the first and 27 in the second) for unresectable pancreatic cancer complicated by mechanical jaundice and gastric evacuation disorders due to duodenal obstruction. Patients of group I performed only biliodigestive shunting by open surgery. Patients in group II obstruction of the bile ducts and duodenum was removed by endoscopic stenting of the biliary system and duodenum with nitinol stents.
Results. It is proved that endoscopic stenting of the biliary system and duodenal obstruction by nitinol stents, compared with open surgery, is accompanied by a lower frequency of postoperative complications (72.7 % vs. 22.2 %, p < 0.05), mortality (27.3 % vs. 0 %, p < 0.001) and reduction of hospital stay (from (24.3 ± 3.74) to (8.7 ± 0.91) days, p <0.001).
Conclusions. The operation of choice of palliative surgical treatment of patients with unresectable pancreatic cancer complicated by mechanical jaundice and evacuation disorders from the stomach, with a high risk of surgery (ASA III), is to perform endoscopic transpapillary stenting of the bile ducts and duodenum.
MULTI-LEVEL OCCLUSIVE-STENOTIC LESIONS OF THE MAIN ARTERIES OF THE INFRARENAL AORTA IN PATIENTS WITH ATHEROSCLEROSIS: ANALYSIS OF TREATMENT AND COMPLICATIONS
Authors: Shaprynskyi V. V. 
Published: October 2022

Resume. The Aim. To analyze the effectiveness of surgical treatment and postoperative complications in patients with multilevel occlusive-stenotic lesions of the main arteries (MOSLMA) of the infrarenal aorta.
Materials and methods. The results of treatment and complications in 51 patients with (MOSLMA) of lower extremities, as a result of obliterating atherosclerosis, were analyzed. Of these, 42 (82.4 %) had two and 9 (17.6 %) three-level lesions. A total of 7 balloon angioplasties and 13 stentings were performed for two and three level lesions in which the iliac arterial segment was affected. Only balloon angioplasty was used for revascularization of the infrainguinal segments.
Results and discussion. In general, regression of ischemia was achieved in 48 (94 %) patients. Of the complications in the early postoperative period, retrombosis was diagnosed in 6 patients. In 3 of them, the limb was saved by thrombolytic therapy and angioplasty. The other 3 patients underwent limb amputation. Mortality in the early postoperative period was 3.9 % (2 patients died as a result of myocardial infarction). An example of successful treatment of a patient with (MOSLMA) and previously stented superficial femoral artery is given.
Conclusions. Patients with (MOSLMA) are a complex category with predominantly aggravated comorbidity. The optimal method of revascularization is endovascular. Arterial puncture under ultrasound guidance helps to reduce complications such as hematomas and false aneurysms. The introduction of a clear algorithm based on preoperative assessment of anatomical and hemodynamic lesions of the arteries, taking into account the severity of the patient’s condition, can give good treatment results.
PSYCHOEMOTIONAL INDICATORS OF PATIENTS WITH PURULONECROTIC COMPLICATIONS OF THE DIABETIC FOOT SYNDROME WHO USED DEVICE FOR OFFLOADING OF FOOT DURING MARTIAL LAW
Authors: Pryimenko D. S. 
Published: October 2022

Abstract. Aim. To study the psychoemotional state of patients with purulent-necrotic complications of diabetic foot syndrome (DFS), who used the device for offloading of foot developed by us during the martial law in Ukraine and to compare it with the results of health-related quality of life indicators in peacetime.
Materials and methods. All operated patients had stage 3 or 4 of the pathological process on the foot according to the Meggitt-Wagner classification, a neuroischemic form of DFS. The first group includes 28 patients who received prescribed treatment before the introduction of martial law in the country; the second group – 24 patients who were treated during martial law. The psychoemotional state of patients with purulent-necrotic complications of DFS was studied on the 1st and 20th days using the «Emotions» subscale from the «Illness Impact Profile» questionnaire; index of general (good) well-being/ WHO, version 1999; hospital anxiety and depression scale.
Results and discussion. The indicators of patients of the first group according to the subscale «Emotions» on the 1st day — (85.7±14.3) points, and of the second group — (104.6±16.1) points. In the group of patients who were interviewed before martial law, the result of the general well-being index was (48.4±1.2). Patients of the second group have (43.5±1.1). Anxiety level: (7.5±0.3) points and (8.7±0.4) points; level of depression: (6.4±0.5) points and (7.6±0.4), respectively. Although the indicators remain unsatisfactory on the 20th day, the tendency towards the improvement of the psychoemotional state is already becoming obvious. The difference in indicators between the two groups remains, which is explained by the influence of military events.
Conclusions. In the second group, worse indicators were found for the psychoemotional component of health-related quality of life, both on the 1st and 20th days. The worse dynamics of the improvement of the specified indicators on the 20th day were recorded. In the first group, according to the «Emotions» subscale, there was an improvement of 63.1 %, in the second group — by 36.2 %; the general well-being index increased by 40.1 % and 25.1 %, respectively. If in the first group, the anxiety index decreased by 16 %, and depression by 20.3 %, then in the second group, the anxiety index decreased by 12.6 %, and depression — by 10.6 %.

Published: October 2022

BACKGROUND & OBJECTIVE: Hypomagnesemia has a detrimental influence on glucose homeostasis and insulin sensitivity in T1DM andT2DM patients, as seen by the progression of DM comorbidities such as arterial atherosclerotic(atherosclerosis), retinopathy, and nephropathy. The objective of this study is to make a comparison and correspond biochemical variants(to analyze the difference) of fasting blood glucose, serum magnesium, and major lipid analytes (serum total cholesterol and triacylglycerol) in diverse medical groups of both T1DM and T2DM.
METHODOLOGY: It was a cross-sectional observational study carried out at Sahiwal teaching hospital, Sahiwal, Pakistan, including 250 research participants. The study used a traditional time-bound sample size of 6 months starting from first March to August 2021through a random selection approach.
RESULTS: Out of 250 participants, 200(80%) of whom(omit) had diabetes mellitus (DM), The number of men with diabetes 110(55%) was greater than the percentage of women with diabetes 90(45%) in this study. 52(26%) of the research participants had T1DM, whereas 148 (74%) had T2DM. A comparison of plasma glucose levels of the three groups was made, and the difference(added) was statistically significant. The difference(added) in serum magnesium, serum total cholesterol, and serum triglycerol among the groups(added) was also statistically significant p<0.05.
CONCLUSION: The current study looked at hypomagnesemia biochemical changes in overt hyperglycemic-hyperlipidemic clinical groups of T1DM and T2DM. In light of the reviewed research findings, it is recommended that serum magnesium can be measured as a routine or extended diagnostic profile investigation in recognized health cases of T1DM and T2DM for early screening, periodic monitoring for deficiency, and better management of clinical cases through supplementation to prevent the development of long-term critical diabetes complications.

Authors: Zainab Tehreem  , Yasir Kazmi  , Muhammad Usman Khalid  , Haroon Mansha  , Muhammad Hassan  , Rabia Majeed  
Published: October 2022

BACKGROUND & OBJECTIVE: Post-burn contracture is the tightening of the skin after a second or third-degree burn with the formation of contracture. Post-burn contractures result in the limitation of movement around a burn area. Burns contractures, if left untreated, may cause limitations in the range of motion and daily living tasks. The purpose of this study was to compare the effects of soft tissue mobilization versus static stretching in post-burn contractures at the elbow and wrist.
METHODOLOGY: A pilot study was conducted, and 36 patients were enrolled. Patients with post-burn contracture were divided randomly into two groups. Allocation of patients in both groups was done by computerized generated list. The treatment frequency was 3 times a week. Numeric pain rating scale (NPRS) and Katz index ADLS scale were used for scoring. Paired t-test was applied to evaluate the data.
RESULTS: The mean age in group A and B were 26.16±7.46 and 28.05±1.27, respectively. Mean score for pre-Katz Index of Group A and B (2.47±0.87, 2.16±0.98), post-Katz Index group A and B (3.29±1.68, 3.05±1.47) with a p-value 0.12 and 0.03 group A and B respectively. The mean score group A and B for pre-NPRS (7.61±1.37, 7.94±1.10), post-NPRS (2.27±1.01, 1.72±1.22) with a p-value<0.001 .
CONCLUSION: It was concluded that static stretching is more effective than soft tissue mobilization.
Cohesive Devices on the Abstracts of Select Research Articles Presented in the International Academic Forum (AIFOR): A Discourse Analysis
Authors: Cabrejas Maribeth Mr. 
Published: October 2022

This linguistic research analysis investigates the cohesive devices found in the Abstract of select Asian Conference of Education 2019 research articles. This study also endeavors to disclose the contributions of the cohesive devices in the comprehensibility of the text. This corpus-based study utilizes qualitative descriptive research that specifically employs the evocative discourse analysis. It considers the use of Halliday and Hassan’s taxonomy on Cohesive devices as a basis for investigation. A total of twenty-eight (28) research abstracts are chosen from abstracts compiled in the program and abstract book of the Asian Conference on Education (ACE) presented during the International Academic Forum (IAFOR) held in Toshi Hotel, Tokyo, Japan last October 31 to November 3, 2019, as the main source of data. The data are analyzed using Halliday and Hasan’s taxonomy of cohesion which is divided into two aspects, grammatical and lexical cohesion. The result of the study reveals that researchers utilize two grammatical cohesions namely: reference and conjunctions in their research abstracts. The conjunctive features of the grammatical device found are additive, causal, adversative, and temporal. Moreover, the referential grammatical devices found are demonstrative, personal, article, and comparative. There is no usage of substitution and elliptical cohesion or ellipsis found. In terms of lexical cohesion, Reiteration devices such as repetition, synonymy, and antonymy are utilized by the researchers in their abstracts. There is no evidence of meronomy found in the analysis. Collocation devices are widely used in the abstract. In the analysis, the presence of the cohesive devices in the abstracts functions to keep track of the participants, organized in logical order the concepts in the abstract, and help in avoiding repetition and text redundancy which significantly contributes to the text comprehensibility of the research abstracts. Thus, the researcher designs and presents an English workbook for classroom use in which the drills provided focus on the correct usage of cohesive devices in any written discourse.
Evidence of Long-term Period Variations in the Exoplanet Transit Database (ETD)
Authors: Hagey Simone R. , Edwards Billy , Boley Aaron C. 
Published: October 2022

Abstract
We analyze a large number of citizen science data and identify eight hot Jupiter systems that show evidence for deviations from a constant orbital period: HAT-P-19 b, HAT-P-32 b, TrES-1 b, TrES-2 b, TrES-5 b, WASP-4 b, WASP-10 b, and WASP-12 b. The latter system is already well known to exhibit strong evidence for tidal orbital decay and serves as an important control for this study. Several other systems we identify have disputed period drifts in the literature, allowing the results here to serve as an independent analysis. The citizen science data are from the Exoplanet Transit Database (ETD), which is a global project established in 2008 by the Variable Star and Exoplanet Section of the Czech Astronomical Society. With over 400 planets and 12,000 contributed observations spanning 15 yr, the ETD is brimming with potential for studying the long-term orbital evolution of close-in hot Jupiters. We use our results to discuss prioritization of targets for follow-up investigations, which will be necessary to confirm the period drifts and their causes.
Search for an Alien Message to a Nearby Star
Authors: Gillon Michaël , Burdanov Artem , Wright Jason T. 
Published: October 2022

Abstract
If alien probes have colonized the whole galaxy, they could have formed an efficient galactic-scale communication network by establishing direct gravitationally lensed links between neighboring systems. Under this scenario, observing the positions opposite the nearest ecliptic stars represents a promising artifact SETI strategy that could make it possible to “eavesdrop” on the emission of local probes to one of these stars. In this context, we present here a first attempt to detect optical messages emitted from the solar system to the ecliptic star Wolf 359, the third-nearest stellar system, based on observations gathered by the TRAPPIST-South and SPECULOOS-South robotic telescopes. While sensitive enough to detect constant emission with emitting power as small as a few watts, this search led to a null result. We note that the putative alien probes could be emitting “off-axis” and be located much closer to the Sun than the start of the “solar gravitational line” at 550 au. We performed a search for such an off-axis emitter in our data, whose result turned out negative too.

Abstract
We report spectropolarimetric observations of the Type Ia supernova (SN) SN 2021rhu at four epochs: −7, +0, +36, and +79 days relative to its B-band maximum luminosity. A wavelength-dependent continuum polarization peaking at 3890 ± 93 Å and reaching a level of

% was found. The peak of the polarization curve is bluer than is typical in the Milky Way, indicating a larger proportion of small dust grains along the sight line to the SN. After removing the interstellar polarization, we found a pronounced increase of the polarization in the Ca ii near-infrared triplet, from ∼0.3% at day −7 to ∼2.5% at day +79. No temporal evolution in high-resolution flux spectra across the Na i D and Ca ii H and K features was seen from days +39 to +74, indicating that the late-time increase in polarization is intrinsic to the SN as opposed to being caused by scattering of SN photons in circumstellar or interstellar matter. We suggest that an explanation for the late-time rise of the Ca ii near-infrared triplet polarization may be the alignment of calcium atoms in a weak magnetic field through optical excitation/pumping by anisotropic radiation from the SN.
On the Convergence of the Milky Way and M31 Kinematics from Cosmological Simulations
Authors: Forero-Romero J. E. , Sierra-Porta D. 
Published: October 2022

Abstract
The kinematics of the Milky Way (MW) and M31, the dominant galaxies in the Local Group (LG), can be used to estimate the LG total mass. New results on the M31 proper motion have recently been used to improve that estimate. Those results are based on kinematic priors that are sometimes guided and evaluated using cosmological N-body simulations. However, the kinematic properties of simulated LG analogs could be biased due to the effective power spectrum truncation induced by the small size of the parent simulation. Here we explore the dependence of LG kinematics on the simulation box size to argue that cosmological simulations need a box size on the order of 1 Gpc in order to claim convergence on the LG kinematic properties. Using a large enough simulation, we find M31 tangential and radial velocities relative to the MW to be in the range

Published: October 2022

Objective: To determine whether there was an improvement in stroke care after the establishment of the Stroke Unit at the Institute of Neurology, National Hospital of Sri Lanka. Design: The process of acute stroke care was evaluated by retrospective case record analysis of 192 patients with stroke admitted to the Stroke Unit. These results were compared with a previous audit of 263 patients treated in the neurology wards. The two audits used identical methodology, and were conducted using an audit package developed by the Royal College of Physicians of London. Methods: Sixty audit items related to stroke care were assessed, and compared between the two audits. Performance for each item was recorded as a percentage, and was graded from ‘very poor’ to ‘very good’. The difference between the two audits for each item was expressed as an odds ratio (OR). Results: Care was graded as ‘very good’ or ‘good’ for 56.7% of audit items, compared to 20% in the first audit. Significant improvements in care (OR>1.0, p<0.05) were noted in 50 out of the 60 audit items. Large improvements were seen in assessment of risk factors, CT scanning, rehabilitation oriented clinical assessments and initiation of secondary preventive measures. Conclusion: Establishment of the Stroke Unit has led to significant improvements in the process of stroke care.
Is testosterone a potential agent for patients with delayed recovery from Guillain-Barre Syndrome?
Authors: Vidanagamage A. S. , Weeratunga L. , Asfir E. L. , Gooneratne K. , Fernando A. 
Published: October 2022

Background: Management of some of the patients with Guillain-Barre syndrome is challenging, requiring weeks to months of intensive care and prolonged institutional care. Case report: We report a 32-year-old male with acute inflammatory demyelinating polyneuropathy (AIDP) with markedly delayed recovery. He was ventilator dependent and multiple therapeutic interventions were attempted. Other possible contributing factors for delayed recovery were looked into. Co-existing critical illness myopathy and polyneuropathy with low level of serum testosterone were detected. Following replacement of testosterone, he was weaned off from the ventilator within a short period of time after eleven weeks of ventilator dependency and slow recovery of neurological weakness had been achieved resulting in total independency and normal working capacity. Conclusion: Delayed recovery in GBS could be multifactorial. The effects of neuroendocrine changes in a critical illness could alter the expected recovery process. Thus, the role of testosterone in recovery from peripheral nerve injury, as well as in critical illness myopathy needs to be looked into.
