Aim: to assess the severity of the pathomorphological response according to the classification of Residual Cancer Burden (RCB) in patients with breast malignancies depending on the surrogate molecular biological subtype after neoadjuvant drug therapy (chemotherapy ± anti- HER2 therapy). Design: Retrospective comparative study. Materials and methods. The retrospective study included 90 patients with breast cancer (T0-3, N0-1, M0) with luminal In HER2-negative, luminal In HER2-positive, HER2-positive non-luminal, thrice negative subtypes who were on complex treatment. The age of women ranged from 26 to 39 years (median age — 36 years). A retrospective analysis of the evaluation of residual tumor load in 85 patients according to the RGB system after neoadjuvant drug therapy and subsequent surgical treatment was performed. Results. In patients with luminal B HER2-negative breast cancer, a complete pathomorphological response was noted in 20% of cases, in 16% — RCB-I, in 36% — RCB-II, in 28% — RCB-III. Among women with luminal B HER2-positive breast cancer, a complete response was achieved in 26.67%, RCB-I was noted in 33.33%, RCB-II — in 13.33%, and RCB-III — in 26.67%. Among the patients with HER2-positive breast cancer, 46.16% had RCB-0, 23,08% had RCB-I, 15.38% each had RCB-II and RCB-III. In participants with thrice negative breast cancer, a complete response was achieved in 41.94% of cases, RCB-I was noted in 22.58%, RCB-II — in 19.35% and RCB-III — in 16.13%. The frequency of complete pathomorphological response (RCB-0) after neoadjuvant chemotherapy significantly differed among the more aggressive subtypes of breast cancer (thrice negative and HER2-positive), compared with HER2-negative (p < 0.0001). Conclusion. The unified assessment of the residual tumor after neoadjuvant therapy makes it possible to clearly identify prognostic groups of patients with different treatment responses and plan additional drug therapy for them. Keywords: neoadjuvant chemotherapy, targeted therapy, breast cancer, HER2.

Authors: Chinapong Songdhasn , Amornsriwatanakul Areekul
Published: May 2023

Objective: To investigate the prevalence of sedentary behavior (SB) and factors associating with meeting the screen time guidelines among the Thai youth using a nationwide population-based survey. Material and Methods: Data from a national representative sample of 3,900 Thai youths aged 14–17 years old across the country were drawn from the Thailand Physical Activity Children Survey. SB was classified into screen time and sitting down activity. The youths were classified as meeting the screen time guidelines if they spent less than 120 min on screen time activities. A logistic regression analysis was conducted to examine the relationship between sociodemographic factors and meeting the screen time guidelines. Results: Overall, 33.7% of Thai youths were highly sedentary; only 30.5% of them met the screen time guidelines. Regarding screen time activity, the participants spent the highest amount of time using online social media; meanwhile, doing homework was the sitting down activity taking the greatest proportion of their time. The youths who were older and engaged in more screen time activities were significantly more likely to meet the screen time guidelines. Moreover, those who resided in regions other than Bangkok and had longer sleep times were significantly more likely to meet the screen time guidelines. Conclusion: The prevalence estimates of meeting the screen time guideline among the Thai youth were low. Age, geographical region of residence, number of engagements in screen time activities, and sleep time were associated with meeting the screen time guidelines. Our findings indicate that public health policies and interventions are needed to reduce SB among Thai youths; particular attention should be paid to the associating factors of SB.

Treatment of STAGE III A NSCLC is an extremely difficult problem for modern oncology, since the one-year survival rate from the moment of diagnosis according to the National Cancer Registry is up to 58%. At the same time, there is a situation of uncertainty in the clinical approach to the treatment of this pathology – neither NCCN nor other world scientific literature sources contain information regarding a specific treatment method. The advantage of none of the possible methods of treatment of stage III NSCLC (HCT, NHLT, HCT + adjuvant PT) is not proven in relation to others. The conducted study is devoted to comparing these methods in relation to each other and overall and relapse-free survival. According to the results of previous studies, the highest results of both general and relapse-free survival were shown by patients from the NHLT group. But an important aspect of treatment is the ratio of benefit and risk, that is, the number and severity of complications. The study and analysis of complications of treatment with the methods of NXT, NHLT and NXT + adjuvant PT was the task of the work. Goal. To investigate and determine the number of complications in groups with NCRT, NCT and NCT + adjuvant LT. Materials and methods. The study included 3 groups of patients – patients who received NHLT, NHT and NHT + adjuvant PT, a total of 304 people. All patients had the same chemotherapy regimen- Cisplatin / Docetaxel or Carboplatin / Paclitaxel, patients receiving radiation therapy received it in a total dosage of 30 Gy in both neoadjuvant and adjuvant regimens. The irradiation was carried out on the chest and mediastinum area. Patients underwent radical surgery in the form of lobectomy, bilobectomy or pneumonectomy. In early works on this topic, an analysis of survival on the Kaplan and Mayer scale was carried out. The article describes the conduct and study of treatment complications that were recorded during the stay of patients in the hospital both during chemotherapy, radiation therapy and in the postoperative period.
Beneficial effects of statins on adropin level in patients with arterial hypertension
Authors: Pokrovska N.K. , Sklyarov E.Y.
Published: May 2023

Introduction. Adropin is a new secretory hormone that takes part in the regulation of energy homeostasis. Hormone is known to have positive effects on endothelial cell proliferation and prevention of atherosclerosis, and low adropin level may be a risk factor and potential predictor of atherosclerosis. Arterial hypertension (AH), which remains one of the most common somatic pathologies among middle-aged and older people, plays an important role in predicting cardiovascular morbidity and mortality. A number of medications that are used as antihypertensive therapy contribute to an increase in the content of adropin. At the same time there are not enough studies on the effect of statins on the content of adropin.

Aim of the study.To investigate the effects of statins on adropin level in patients with AH.

Material and methods. 70 patients with hypertension aged 62,1 ± 9,9 years were examined. They were divided into 2 groups: 1 group – patients with AH, overweight and obesity who did not take statins (n=40); group 2 – persons with AH, overweight and obesity who took statins (n=30). All individuals underwent determination of basic indicators of biochemical blood analysis, lipid profile (total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), triglycerides (TG), atherogenicity ratio). The level of adropin was determined by enzyme immunoassay (Finetest Elisa Kit) in blood serum.

Results. Systolic blood pressure (BP) was significantly higher in group 1 individuals (p<0.05), while diastolic BP remained unchanged (p>0.05). Among patients who took statins, a significantly lower level of TC, LDL, atherogenicity ratio (p<0.01), HDL (p<0.05) was found, while the level of TG remained unchanged.

Taking statins and achieving the target level of LDL improves the prognosis of patients with cardiovascular pathology, as evidenced by a significant increase in the content of adropin in blood serum in patients of the 2nd group. In women who took statins, a direct correlation was found between the level of adropin and HDL (r=0.609; p<0.05).

Conclusions. Taking statins is associated with significantly higher levels of adropin in patients with AH compared to individuals who did not take these drugs. A direct correlation was noted between the level of adropin and HDL in women who took statins. Statins effectively reduce atherogenic fractions of cholesterol and help to increase the concentration of adropin in blood serum.

Published: May 2023

Introduction: the relevance of determining the effectiveness of early rehabilitation of patients after an ischemic stroke is high, as it solves a number of important medical and social problems of society.

The aim: to determine the possibilities and effectiveness of early rehabilitation of patients after an ischemic stroke according to the data of literary sources.

Materials and methods: the research was conducted based on the results of the analysis of the world results of scientific research and the existing mechanisms and documents of international societies for determining the possibilities and effectiveness of early rehabilitation of patients after an ischemic stroke. The search for scientific information was performed using domestic and foreign Internet resources of Google Scholar, PubMed, Medscape, Scopus and Web of Science databases, etc.

The results of the study: It was determined that the primary and quite effective measure in the treatment of patients after an ischemic stroke is the early start of rehabilitation measures, which improves the survival of brain cells due to an increase in cerebral blood flow, which reduces ischemic necrosis of neurons and revitalizes part of neurons and significantly reduces the post-stroke level disability of patients. It was established that a significant yet undetermined issue in early rehabilitation is the effectiveness of early mobilization and its intensity, and the effectiveness of the rehabilitation strategy is entirely based on the correct combination of the time from the onset of the stroke and the intensity of mobilization

Conclusions: the study determined that early rehabilitation intervention in ischemic stroke is significantly effective and economically feasible, and the effectiveness and feasibility of early intensive mobilization is currently a rather controversial issue.
EXAMINATION DIRECTIONS AS A COMPONENT OF PHYSICAL THERAPY, FOR CHILDREN WITH BRONCHOPULMONARY DISEASES FROM THE POINT OF VIEW OF THE INTERNATIONAL CLASSIFICATION OF FUNCTIONING, DISABILITY AND HEALTH
Authors: Ivasyk N. O.
Published: May 2023

Introduction. The Ministry of Economy of Ukraine, by its order No. 810-22 of April 9, 2022, approved the International Classification of Functioning, Limitations of Vital Activities and Health (ICF) as National Classifier NC 030:2022. This, in turn, requires appropriate approaches to both the entire rehabilitation process and its components.

Purpose: to model the components of examination directions, as a component of the physical therapy program, for children with bronchopulmonary diseases, according to the international classification of functioning, limitations of life activities and health.

Methods: General and specialized methods of cognition: analysis, generalization, systematization and comparison of information from scientific and methodical literature on the problems of physical therapy in bronchopulmonary diseases.

Results. Rehabilitation examination of children with bronchopulmonary diseases includes both objective and subjective assessments, as well as observations, which are interconnected. Changing the focus from the classification of «disease consequences» to «health components», which is the basis of the ICF, requires looking at the examination component in the process of physical therapy from the side of the health components of a child with bronchopulmonary diseases. Based on this, we considered the examination as a component of the physical therapy program for children with bronchopulmonary diseases, classified using the ICF model. In our approach, we determined the main directions of the examination, based on the components of the ICF, since when selecting tests and scales, the child’s age and development must be taken into account first and foremost.

Conclusions. Rehabilitation examination is a component of physical therapy, which is carried out with the aim of determining a rehabilitation diagnosis and is based on subjective, objective assessments and observational data. In this work, we identified the main directions for choosing examination methods based on ICF, which will contribute to the selection of examination tools, determining their priorities, and formulating a categorical profile of patients with bronchopulmonary diseases.

Authors: Singjie Leonard Christianto , Kusuma Samuel Andi , Saleh Ifran , Kholinne Erica
Published: May 2023

Low back pain is one of the leading causes of disability in the world. Regenerative medicine can be one of the novel treatment breakthroughs in patients with low back pain, yet its use is still debatable. We performed a systematic evaluation and meta-analysis to determine the efficacy of platelet-rich plasma (PRP) treatment for patients with chronic low back pain. Comprehensive database searches were performed in four databases. This study was conducted and reported based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses Guideline and registered to PROSPERO. We included and examined randomized controlled trials that looked into research employing PRP for patients with chronic low back pain. Outcomes of interest include clinical enhancement of pain, which is demonstrated in pain scores. Three studies were included comprising 138 patients with chronic low back pain. After 1, 3, and 6 months after injection, there was a substantial reduction in the pain score difference between the PRP and control groups, demonstrating PRP’s superiority over the control group in the treatment of chronic low back pain. PRP injection significantly enhances chronic low back pain in the first, third, and sixth months after injection compared to controls.

OBJECTIVE

Adolescent participation in athletics continues to grow, leading to an increasing incidence of sports-related concussion (SRC). The current literature suggests that a greater number of prior concussions positively correlates with a greater number of total symptoms, but the specific concussion-related symptoms are not as well defined. The current study investigated the effects of prior recurrent head injury on the symptom profiles of student-athletes after another suspected concussion.

METHODS

A multicenter database consisting of 25,815 Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) results was filtered for student-athletes aged 12–22 years old who competed in 21 different sports. Patients were separated into 2 cohorts: athletes reporting a single prior concussion (SRC1) and athletes reporting 2 or more prior concussions (SRC2+). Comparisons were assessed for differences in 22 symptoms and 4 symptom clusters at baseline, first postinjury test (PI1), and second postinjury test (PI2) by using univariate and multivariate analyses.

RESULTS

No differences were seen between SRC1 (n = 2253) and SRC2+ (n = 976) at baseline. At PI1, the SRC2+ group (n = 286) had lower severity of headaches (p = 0.04) but increased nervousness (p = 0.042), irritability (p = 0.028), sadness (p = 0.028), visual problems (p = 0.04), and neuropsychiatric symptoms (p = 0.009) compared with SRC1 (n = 529). Multivariate analysis revealed decreased headache severity with increased prior concussion (β = −0.27,95% CI −0.45 to −0.09, p = 0.003). Multivariate analysis at PI2 demonstrated the SRC2+ cohort (n = 130) had increased cognitive (β = 1.22, 95% CI 0.27–2.18, p = 0.012), sleep (β = 0.63, 95% CI 0.17–1.08, p = 0.007), and neuropsychiatric (β = 0.67,95% CI 0.14–1.2,0.014) symptoms compared with SRC1 (n = 292).

CONCLUSIONS

At longitudinal follow-up, patients with a history of recurrent concussions reported greater symptom burden in cognitive, sleep, and neuropsychiatric symptom clusters but not migraine symptoms. This is an important distinction because migraine symptoms are often more easily distinguishable to patients, parents, and physicians. Careful assessment of specific symptoms should be considered in patients with a history of recurrent head injury prior to return to play.

Authors: Maddy Krisna , Eliahu Karen , Bryant Jean-Paul , Garcia Roxanna , Du Rebecca , Lam Sandi , Niazi Toba N.
Published: May 2023

OBJECTIVE

The aim of this scoping review was to identify relevant articles that have contributed to the body of knowledge describing pediatric neurosurgical healthcare disparities. Identifying healthcare disparities in pediatric neurosurgery is essential to understanding how to best provide care for this unique patient population. Although it is undoubtedly important to increase the knowledge of pediatric neurosurgical healthcare disparities, it is also important to understand the current state of the literature.

METHODS

This scoping review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. The search terms "pediatric neurosurgical disparities" and "pediatric neurosurgical inequities" were entered into the following databases: PubMed, Scopus, and Embase.

RESULTS

The initial database search returned a total of 366 results from the PubMed, Embase, and Scopus databases. One hundred thirty-seven duplicates were removed, and the remaining articles were screened by title and abstract. Articles were excluded on the basis of the inclusion and exclusion criteria. Of the remaining 229 articles, 168 were excluded. Sixty-one full-text articles were then examined for eligibility, and 28 did not reach the specified inclusion and exclusion criteria. The remaining 33 articles were included for final review. The results of the reviewed studies were stratified on the basis of disparity type.

CONCLUSIONS

Although there has been an increase in the number of publications discussing pediatric neurosurgical healthcare disparities within the last decade, there still remains a scarcity of information regarding healthcare disparities in neurosurgery. Furthermore, less information exists that specifically addresses healthcare disparities in the pediatric population.

Published: May 2023

OBJECTIVE

The aim of this study was to investigate the diagnostic performance, effective radiation dose, and examination time of ventriculoperitoneal shunt evaluation using full-body ultra-low-dose CT (ULD CT) with a tin filter compared with digital plain radiography in a pediatric population.

METHODS

A retrospective cross-sectional study was conducted in an emergency setting. Data from 143 children were collected. Sixty were examined with ULD CT with a tin filter and 83 with digital plain radiography methods. Effective doses and times were compared between the two methods. Two observers in pediatric radiology evaluated the patient images. Clinical findings and results from shunt revision, if it was performed, were used to evaluate the diagnostic performance between modalities. An examination-room simulation was performed of the two methods to estimate representative examination times.

RESULTS

The mean effective radiation dose for ULD CT with the tin filter was estimated to be 0.29 ± 0.16 mSv compared with 0.16 ± 0.19 mSv for digital plain radiography, with both examinations associated with a very low lifetime attributable risk (< 0.01%). The shunt tip could be more reliably located with ULD CT. ULD CT also allowed assessment of additional findings to explain patient symptoms, such as a cyst at the tip of the shunt catheter and the presence of an obstructing rubber nipple in the duodenum that could not have been observed on a plain radiograph. The examination time with ULD CT of the shunt was estimated to be 20 minutes. The examination time of the shunt with digital plain radiography, including the examination itself time and transfer of the patient between rooms, was estimated to be 60 minutes.

CONCLUSIONS

ULD CT using a tin filter allows good visualization of the position or disruption of the shunt catheter that is comparable or superior to plain radiography, at a higher dose, while providing additional findings and reduced patient discomfort.

Published: May 2023

OBJECTIVE

The aim of this study was to investigate time-dependent rates and indications of unplanned reoperation and to evaluate the most common indication depending on the time interval after pedicle subtraction osteotomy (PSO) for correction of thoracolumbar kyphosis in patients with ankylosing spondylitis (AS).

METHODS

A total of 321 consecutive patients with AS (284 men; mean age 43.8 years) with thoracolumbar kyphosis who underwent PSO were included. Patients who underwent reoperation after the index surgery were divided according to the duration of the follow-up period.

RESULTS

A total of 51 patients (15.9%) underwent unplanned reoperations. The reoperation groups had greater preoperative and postoperative C7 sagittal vertical axis (SVA), and less lordotic postoperative osteotomy angle (−4.3° ± 18.6° vs −15.0° ± 13.7°, p < 0.001). The perioperative change in SVA was not significantly different between groups (−10.0 ± 7.1 cm vs −10.0 ± 5.1 cm, p = 0.970), while that in the osteotomy angle was significantly different (−22.4° ± 21.3° vs −30.0° ± 11.5°, p = 0.014). Most reoperations (45.1%; 23/51) were performed within 2 weeks of the initial operation. Within 2 weeks, the most common cause of reoperation was neurological deficit in 10 patients, with a cumulative reoperation rate of 3.2%. After 3 years, the most common complications were mechanical complications in 8 patients, accounting for 15.7% (8/51) of patients. Overall, the most common indications for reoperation were mechanical complications (17 patients; 5.3%), followed by neurological deficits (12 patients; 3.7%).

CONCLUSIONS

PSO may be the most effective surgical procedure for the correction of thoracolumbar kyphosis in patients with AS. However, 51 patients (15.9%) required an unplanned reoperation.

OBJECTIVE

The objective of this paper was to report mechanical complications and patient-reported outcome measures (PROMs) for adult spinal deformity (ASD) patients with a Roussouly "false type 2" (FT2) profile.

METHODS

ASD patients treated from 2004 to 2014 at a single center were identified. Inclusion criteria were pelvic incidence ≥ 60° and a minimum 2-year follow-up. FT2 was defined as a high postoperative pelvic tilt (PT), as defined by the Global Alignment and Proportion target, and thoracic kyphosis < 30°. Mechanical complications, defined as proximal junctional kyphosis (PJK) and/or instrumentation failure, were determined and compared. Scoliosis Research Society–22r (SRS-22r) scores were compared between groups.

RESULTS

Ninety-five patients (normal PT [NPT] group 49, FT2 group 46) who met the inclusion criteria were identified and studied. Most surgeries were revisions (NPT group 30 [61%], FT2 group 30 [65%]), and most were performed via a posterior-only approach (86%) (mean ± SD 9.6 ± 5 levels). Proximal junctional angles increased after surgery in both groups, without differences between groups. Neither rates of radiographic PJK (p = 0.10), revision for PJK (p = 0.45), nor revision for pseudarthrosis (p = 0.66) were different between groups. There were no differences between groups for SRS-22r domain scores or subscores.

CONCLUSIONS

In this single-center experience, patients with high pelvic incidence fixed with persistent lumbopelvic parameter mismatch and engaged compensatory mechanisms (Roussouly FT2) had mechanical complications and PROMs not different from those with normalized alignment parameters. Compensatory PT may be acceptable in some cases of ASD surgery.
Identification of Inability States of Rotating Machinery Subsystems Using Industrial IoT and Convolutional Neural Network – Initial Research

Published: May 2023

Rotating parts can be found in almost all operational equipment in the industry and are of great importance for proper operation. However, reliability theory explains that every industrial system can change its state when failure happens. Predictive maintenance as one of the latest maintenance strategy emerged from the Maintenance 4.0 concept. Nowadays, this concept can include Industrial Internet of Things (IIoT) devices to connect industrial assets thus enable data collection and analysis that can help make better decisions about maintenance activity. Robust data acquisition system is a prerequisite for any modern predictive maintenance task as it provides necessary data for further analysis and health assessment of the industry asset. Fault diagnosis is an important task in the maintenance of industrial rotating subsystems, considering that early state change diagnosis and fault identification can prevent system failure. Vibration analysis in theory and practice is considered a correct technique for early detection of state changes and failure diagnostics of rotating subsystems. The identified technical state should be considered in a context of the ability and different inability states. Therefore, early different inability states identification is the next step in the rotary machinery diagnostics procedure. Most of the existing techniques for fault diagnosis of rotating subsystems that use vibrations involve the step of extracting features from the raw signal. Considering that the features that describe the behavior of the rotary subsystem can differ significantly depending on the type of equipment, such an approach usually requires an expert in the field of signal processing and rotary subsystems who can define the necessary features. Recently, the emergence of machine deep learning and its application in maintenance promises to provide highly efficient fault diagnostics while simultaneously reducing the need for expert knowledge and human labour. This paper presents authors aim to use self-developed IIoT system built as an IIoT accelerometer as the edge device, web API and database with convolutional neural network as deep learning-based data-driven fault diagnosis to detect and identify different inability states of rotating subsystems. Large dataset for two different rotational speed is collected using IIOT system and multiple convolutional neural network models are trained and tested to examine possibility of using IIOT for inability state prediction.
