Implementation of universal screening for substance use in pregnancy in a public healthcare system

ObjectiveScreening questionnaires are one option for identification of at-risk substance use and substance use disorder (SUD) during pregnancy. We report the experience of a single institution following universal implementation of a brief screening tool for self-reported substance use at the first prenatal encounter. Study DesignThis is a prospective implementation study evaluating screening for substance use in pregnancy in a large safety net healthcare system. Universal screening with the National Institute of Drug Abuse (NIDA) Quick screen V1.0 was integrated into the electronic medical record (EMR) and administered at the first point of contact with the healthcare system. SUD was identified initially with diagnosis within the EMR by a healthcare provider and was confirmed with toxicology (maternal or neonatal) results corroborating a pattern of substance use and maternal and neonatal ICD-10 codes for SUD. Patients identified with SUD were then classified as moderate or severe SUD based on criteria established by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-V). We measured rates of NIDA implementation across different healthcare settings, evaluated NIDA concordance with ascertainment of SUD, and compared adverse pregnancy outcomes associated with moderate and severe SUD. ResultsFrom July 28,2021 through June 25, 2022, 14,634 unique pregnant individuals accessed care at ambulatory and acute care sites. Universal implementation of the NIDA Quick Screen identified at-risk substance use in 2,146 (14.7%) of those who accessed our system, or 17.1% of 12,550 screened across the system, with greater screen completion in ambulatory over acute care settings. SUD was identified in 256 (1.7%) of 14,634 individuals and moderate or severe SUD was identified in 184 (1.3%). Among those with moderate or severe SUD, 90 (48.9%) were NIDA positive, 22 (12.0%) NIDA negative and 72 (39.1%) unscreened. Of 94 individuals with NIDA discordance or who were unscreened 76 (81%) accessed initial care through an acute care setting. Of 96 individuals with opioid use disorder, 68 (70.8%) were treated with medication assisted therapy and 56 (58.3%) were screened with the NIDA Quick Screen. Among delivered individuals with available outcomes, those with moderate or severe SUD were less likely to seek prenatal care (71(76%) vs 9852(98%), <0.001)) and more likely to deliver before 37 weeks, (18(20%) vs 909(9%), RR(95%CI) 2.13(1.40,3.24)) compared to individuals without SUD. Neonates exposed to moderate or severe SUD were more likely to have birth weight <10th centile for gestational age (20(22%) vs 1147(12%), RR(95%CI) 1.92(1.29,2.85)) and require admission to the neonatal intensive care unit (NICU) (19(21%) vs 964(10%), RR(95%) 1.95 (1.30,2.93)). ConclusionUniversal screening was implemented across a large public healthcare system at a high rate, with higher rates of implementation in ambulatory settings. NIDA successfully identified at-risk substance use in 17% of the SUD cohort but failed to identify more than 50% of patients with moderate or severe SUD. Patients with moderate and severe SUD accessed care primarily through the ED and experienced higher rates of adverse obstetric and neonatal outcomes. Future efforts to identify, engage and retain this highest risk group are needed.

Adverse childhood experience, adopting a healthy lifestyle in adulthood, and risk of cardiovascular diseases

BackgroundBoth adverse childhood experiences (ACEs) and lifestyle factors have been associated with risk of cardiovascular diseases (CVDs) in later life, but whether and to what extent adherence to a healthy lifestyle in adulthood can offset the increased cardiovascular risk associated with ACEs is unclear. We aimed to determine whether and to what extent adopting to a healthy lifestyle in adulthood can offset the risk of CVDs in individuals according to their ACEs. MethodsA prospective cohort study included 143,869 participants aged 38–72 years, free of CVDs at baseline from the UK Biobank. The history of ACEs was assessed using the Childhood Trauma Screener. Participants were divided into three risk groups based on ACEs: low (no ACEs), intermediate (one or two ACEs), and high (three or more ACEs). A healthy lifestyle score in adulthood was constructed as the sum of four modifiable lifestyle factors (no smoking, adequate physical activity, healthy diet, no obesity), and participants were then categorized into three groups based on this score (unfavorable [0–1 point], intermediate [2–3 points], favorable [4 points]). Cox proportional hazard models were conducted to investigate the association between ACEs, healthy lifestyle, and incident CVDs. ResultsDuring a median follow-up of 12.49 years, 13,373 incident cases of overall CVDs were identified. This included 7521 cases of coronary heart disease (CHD), 6175 cases of atrial fibrillation (AF) and 1813 cases of stroke. Individuals with high ACEs had a greater risk of incident overall CVDs (hazard ratio [HR] = 1.39, [95%CI = 1.29 to 1.50]), CHD (1.50 [1.36 to 1.65]) and AF (1.18 [1.05 to 1.33]) compared to those with low ACEs. The risk of CVDs decreased moving from unfavorable to favorable lifestyle categories (P for trend<0.001), with the lowest risk observed among individuals with a favorable lifestyle (0.70 [0.66 to 0.74] for overall CVDs, 0.69 [0.64 to 0.75] for CHD, and 0.71 [0.65 to 0.78] for AF). Participants with high ACEs and a favorable lifestyle had a 39 %, 40 % and 47 % lower risk of developing overall CVDs (0.61 [0.48 to 0.76]), CHD (0.60 [0.44 to 0.81], and AF (0.53 [0.36 to 0.77]) than those with high ACEs and an unfavorable lifestyle. ConclusionsHaving a healthy lifestyle in adulthood could substantially attenuate the increased risk of overall CVDs, CHD, and AF conferred by ACEs.

Comparison of the effects of single injection and continuous infusion popliteal nerve block on pain and hemodynamics in diabetic foot surgery; prospective randomized clinical trial

ObjectivesIn patients undergoing surgery due to diabetic foot complications from uncontrolled diabetes may lead to neuraxial or general anesthesia-related issues. Regional anesthesia techniques can be preferred to prevent these complications. This study aimed to compare the hemodynamic effects and outcomes in terms of pain of continuous infusion and single injection methods of popliteal nerve block in patients undergoing surgery due to diabetic foot. Materials and methodsSixty-three patients in ASA II-IV risk group scheduled for diabetic foot surgery were randomized into two groups for popliteal nerve block as the anesthesia method. Group 1 (n:32), 30 mL of local anesthetic was administered around the popliteal nerve under ultrasound guidance and nerve stimulator. Group 2 (n:31) had a catheter placed beyond the needle tip by 4–5 cm. An elastomeric pump was prepared for the infusion of 2 mL/h of 0.25 % bupivacaine through the catheter. Hemodynamic parameters before and after the block, onset, block duration times, postoperative pain scores, time to analgesic requirement, patient satisfaction, and discharge time were recorded. ResultsPain scores were higher in Group 1 after 12 h postoperatively and in Group 2 after 60 h postoperatively (p = 0.006, p < 0.01, respectively). The time to the first analgesic requirement was not statistically different between Group 1 (mean 804.64 ± 1020.8 min) and Group 2 (mean 2012.78 ± 1424 min) (p = 0.072). There was no significant difference in systolic, diastolic, mean arterial blood pressure, and heart rate between groups before and after successful blockade (p > 0.05). ConclusionsContinuous infusion method of popliteal nerve block provides a longer pain-free period. Both methods showed similar hemodynamic data and low pain scores. Although continuous infusion method provides better analgesia, its procedural cost, technical difficulties, and adverse effects on patient comfort should also be considered.

B2 Prognostic Index in Determining Prognosis in Metastatic Breast Cancer.

To determine the relationship between the B2 prognostic index (B2PI) scoring method and prognosis in metastatic breast cancer, and to create a formula based on parameters that can be easily accessed in daily practice. Descriptive study. Place and Duration of the Study: Department of Medical Oncology, Dokuz Eylul University, Izmir, Turkiye, between May 2010 and June 2021. The clinicopathological characteristics of the patients were compared between the groups. All female breast cancer patients over the age of 18 years with de novo metastatic and non-metastatic breast cancers who developed metastasis during follow-up, were included in the study. Those with a second solid cancer or haematological malignancy and with a life expectancy of less than 3 months were excluded from the study. Chi-square and Fisher's exact tests were used to compare categorical data between the groups. Overall survival evaluations were made using the Kaplan-Meier analysis method and Log-Rank test. Risk factors for mortality were evaluated in Cox regression analysis. In all statistical tests, p <0.05 was considered statistically significant. There were 176 patients in this study, out of which 111 (63.1%) were de novo metastatic. When the effect of B2PI risk groups on overall survival in intrinsic subtypes was analysed, significant differences were found in the overall survival of B2PI risk groups in all subtypes except HER2+ ER- (HER2 overexpression subtype). According to the B2PI scoring system, the median overall survival was higher for both low-risk and moderate-risk patients compared to those in the high-risk category. For metastatic breast cancer patients, the B2PI can be used to determine prognosis and develop treatment strategies, as it is a clinical decision-making tool based on parameters that are easily accessible in daily practice. Metastatic breast cancer, B2 prognostic index, Prognosis, Survival.

Evaluation of the prognostic value of papillary muscle-free strain in patients with hypertrophic cardiomyopathy.

The prognosis of hypertrophic cardiomyopathy (HCM) varies from mild disease with a normal life expectancy to heart failure and sudden cardiac death (SCD). The identification of patients who are at high risk for SCD remains challenging. In this study, we evaluated the prognostic value of papillary muscle-free strain in HCM patients. Seventy-nine patients with a diagnosis of HCM were included in this study. Patients were divided into low/intermediate-risk (n=57) and high-risk (n=22) groups. Two-dimensional (2-D) echocardiography and strain imaging were performed for each patient. The mean age of the study population was 53.85±15.88 years; 47 (59.5%) of them were male. During a mean follow-up duration of 74.45±17.03 months, 12 patients died. A comparison of the low-intermediate and high-SCD risk groups revealed that patients in the high-SCD risk group had greater maximal wall thickness, interventricular septum thickness, posterior wall thickness, and left ventricular mass index (LVMI) and lower (less negative) global longitudinal, anterolateral papillary muscle (ALPM) and posteromedial papillary muscle (PMPM) free strain. Additionally, a history of syncope and ICD implantation were found to be more common in patients with high SCD risk scores. The SCD risk score was positively correlated with the global longitudinal strain, ALPM-free strain, and PMPM-free strain (r=.528, r=.658, and r=.600, respectively; p<.001 for all). Our results showed that the LVMI, presence of syncope, global longitudinal strain, and ALPM-free strain were predictors of death. Decreased papillary muscle-free strain values might have prognostic value in patients with HCM.

Identification of risk groups for advanced liver fibrosis in the general population using the Fibrosis-3 index.

We conducted a study using the Fibrosis-3 (FIB-3) index, which is the established age-independent index of fibrosis in nonviral liver disease and addresses the limitations of the FIB-4 index in older age group, to assess the liver fibrosis risk among diverse demographic groups in the general population. We analyzed 31 327 individuals who underwent health examinations between 2013 and 2020 and investigated the distribution of the FIB-3 index by age group. In addition, we examined the age distribution of the FIB-3 index stratified by background factors, such as sex, body mass index (BMI), alcohol consumption habits, and the presence or absence of fatty liver. In terms of age-specific distribution, the FIB-3 index remained below 1.5 in >90% of cases until the age of 50 years but exceeded 1.5 beyond the age of 50 years, in approximately 30% among those aged 70 years. Notably, the FIB-3 index above 31 years old was significantly higher in men than in women. Among the different BMI categories, individuals with BMI < 18.5 exhibited the highest prevalence of fibrosis. Habitual drinkers had a higher proportion with FIB-3. index ≥1.5, and some had FIB-3 index ≥2.5, raising the suspicion of advanced hepatic fibrosis. No distinct association was identified between the FIB-3 index and the presence of fatty liver. The FIB-3 index was useful for identifying cases of advancing hepatic fibrosis in a health checkup population. Liver fibrosis progresses with age in the general population, especially among men, those with low BMI, and habitual drinkers.

Nutritional Indices Predict All Cause Mortality in Patients with Multi-/Rifampicin-Drug Resistant Tuberculosis.

Multidrug- and rifampicin-resistant tuberculosis (MDR/RR-TB) with high mortality remains a public health crisis and health security threat. This study aimed to explore the predictive value of nutritional indices for all-cause mortality (ACM) in MDR/RR-TB patients. We retrospectively recruited MDR/RR-TB patients between January 2015 and December 2021, randomly assigning them to training and validation cohorts. Patients were divided into high nutritional risk groups (HNRGs) and low nutritional risk groups (LNRGs) based on the optimal cut-off value obtained from receiver operating characteristic (ROC) analyses of the hemoglobin-albumin-lymphocyte-platelet (HALP) score, prognostic nutritional index (PNI), and controlling nutritional status (CONUT) score. In the training cohort, Kaplan-Meier survival curves and Log rank tests were used to compare overall survival (OS) between the groups. Cox risk proportion regression analyses were used to explore the risk factors of ACM in patients with MDR/RR-TB. The predictive performance of ACM was assessed using area under the curve (AUC), sensitivity and specificity of ROC analyses. A total of 524 MDR/RR-TB patients, with 255 in the training cohort and 269 in the validation cohort, were included. Survival analyses in the training cohort revealed significantly lower OS in the HNRGs compared to the LNRGs. After adjusting for covariates, multivariate analysis identified low HALP score, low PNI and high CONUT score were independent risk factors for ACM in MDR/RR-TB patients. ROC analyses demonstrated good predictive performance for ACM with AUCs of 0.765, 0.783, 0.807, and 0.811 for HALP score, PNI, CONUT score, and their combination, respectively. Similar results were observed in the validation set. HALP score, PNI, and CONUT scores could effectively predict ACM in patients with MDR/RR-TB. Hence, routine screening for malnutrition should be given more attention in clinical practice to identify MDR/RR-TB patients at higher risk of mortality and provide them with nutritional support to reduce mortality.

Decrease in active hepatitis C infection among people who use drugs in Madrid, Spain, 2017 to 2023: a retrospective study.

BackgroundPeople who use drugs (PWUD) are a key target population to reduce the burden of hepatitis C virus (HCV) infection.AimTo assess risk factors and temporal trends of active HCV infection in PWUD in Madrid, Spain.MethodsWe conducted a retrospective study between 2017 and 2023, including 2,264 PWUD visiting a mobile screening unit. Data about epidemiology, substance use and sexual risk behaviour were obtained through a 92-item questionnaire. HCV was detected by antibody test, followed by RNA test. The primary outcome variable was active HCV infection prevalence, calculated considering all individuals who underwent RNA testing and analysed by logistic regression adjusted by the main risk factors.ResultsOf all participants, 685 tested positive for anti-HCV antibodies, and 605 underwent RNA testing; 314 had active HCV infection, and 218 initiated treatment. People who inject drugs (PWID) were identified as the main risk group. The active HCV infection rate showed a significant downward trend between 2017 and 2023 in the entire study population (23.4% to 6.0%), among PWID (41.0% to 15.0%) and PWUD without injecting drug use (7.0% to 1.3%) (p < 0.001 for all). These downward trends were confirmed by adjusted logistic regression for the entire study population (adjusted odds ratio (aOR): 0.78), PWID (aOR: 0.78), and PWUD non-IDU (aOR: 0.78).ConclusionsOur study demonstrates a significant reduction in active HCV infection prevalence among PWUD, particularly in PWID, which suggests that efforts in the prevention and treatment of HCV in Madrid, Spain, have had an impact on the control of HCV infection.

Distinct transcriptional and prognostic impacts of TERT promoter mutations C228T and C250T in papillary thyroid carcinoma.

TERT promoter mutations C228T and C250T are associated with disease aggressiveness and poor clinical outcomes in patients with papillary thyroid carcinomas. However, very little is known about the transcriptional consequences of these mutations and whether they both carry similar oncogenic potential. Here we characterized the transcriptional disturbances and clinical outcomes associated with the presence of each of these two mutations using data derived from The Cancer Genome Atlas. We observed that tumors harboring the C228T mutation (n=27) exhibited a 16-fold increase in TERT mRNA levels (P=5.3x10-42), whereas C250T tumors (n=8) showed only a 2-fold increase in expression (P=0.034). The C228T mutation was associated with the activation of signaling pathways controlling the cell cycle, cellular division, and extracellular matrix degradation. Univariate analysis demonstrated that the C228T mutation was associated with older age at diagnosis, large tumor size, lymph node invasion, and distant metastases at diagnosis. The C228T mutation was also associated with worse progression-free interval (PFI) in comparison to WT tumors (HR=5,04; P<0.001). This association remained significant in a multivariate analyses (HR=3.74, P=0.003) adjusting for BRAF-V600E status and ATA risk group. Our data indicate that TERT promoter mutations C228T and C250T have distinct transcriptional consequences in PTC, suggesting a greater oncogenic potential for the C228T mutation. TERT promoter mutation C228T may be a useful prognostic marker to identify patients at high risk of distant recurrence. Clinical data for the C250T mutation is still limited, with no evidence up to date to confirm its prognostic significance.

Myelomeningocele operated in utero and the incontinent bladder pattern: Mid-term follow up of a prospective study

In-utero myelomeningocele repair is the gold standard treatment after the publication of the MOMS trial. We have performed a retrospective analysis from our prospective in-utero myelomeningocele closure database (started in 2011), and selected only patients with the incontinent bladder pattern according to the Leal da Cruz categorization (Leal da Cruz, etal. J Urol 2015) to review mid-term clinical outcomes. We identified 30 patients with leaking pressure under 40 cmH20 (incontinent pattern) at first urodynamic evaluation (UE) from the whole cohort of 129 patients who underwent in-utero myelomeningocele closure. We selected patients with a minimum active follow-up of 48 weeks (4 years) to provide mid-term data. Patients were followed according to the same protocol with the proposal of yearly sonogram and UE. All clinical and radiological data were reviewed. We found 11 patients, with a mean age of 10.2 years old, median age at diagnosis of 19 weeks, surgery performed at 25.6 weeks and birth at 33.2 weeks. The mean follow-up was 81.73 months (6.81 years). Mean age at first urological evaluation was 5 months, and UE was 5.6 months. Febrile UTI incidence in the whole observation period was 27.3%. The average initial DLPP was 30 cmH2O. 71.4% of the patients had bladder capacity less than 50% of the expected age. Bladder compliance could not be determined in 63.7% of cases due to leakage. A total of 5.7 urodynamic studies per patient were performed. Surgery was recommended for 8 patients and done in 4 (36.3%). Surgery consisted of Macedo catheterizable reservoir and Macedo-Malone ACE, associated with urethral sling (2 patients) and bladder neck closure (2). It took an average of 5 UE before the final surgical decision was confirmed. Last urodynamic study showed persistent leakage and low DLPP in 3 patients, normal bladder pressure in 2 (under CIC and anticholinergics), and 1 patient changed his bladder pattern into a high risk group. All operated patients are fully continent (urinary >4hs) and fecal. Despite initially presenting a low risk for the most patients, we found surgery in 36.3% (4/11) and if we considered all cases with surgery indication proposed to treat urinary incontinence it would be even higher (72.7%).

Construction and validation of a prognostic and therapeutic cuproptosis- and immune-related gene signature in hepatocellular carcinoma.

Abnormal accumulation of copper could induce cell death and tumor growth, and affect tumor immune escape by regulating programmed cell death ligand 1 (PD-L1) expression. This study aims to establish and verify a risk signature based on cuproptosis- and immune-related genes (CIRGs) for hepatocellular carcinoma (HCC) management. HCC RNA-seq and clinical data were obtained from open databases. Least absolute shrinkage and selection operator (LASSO) and Cox regression analyses were utilized to screen CIRGs and develop a risk signature. The signature's value for clinical applications, functional enrichment, tumor mutation burden (TMB), and immune profile analyses were investigated systematically. A risk signature was developed utilizing seven CIRGs, and it performed well in predicting the prognosis of HCC patients in both the training and external validation cohorts. The model's risk score was discovered to be related to important clinical features. Top 15 mutated genes in HCC were significantly different among different risk groups. High-risk patients showed higher TMB, and high TMB was closely identified with a poorer prognosis. Immune profile analyses showed that immune infiltration level was higher in low-risk patients than high-risk patients, and the level of immune checkpoint genes expression varied significantly between patients in two different risk groups. Low-risk patients responded well to immunotherapy treatment, whereas high-risk patients were more sensitive to sorafenib, doxorubicin, gemcitabine and AKT (also known as protein kinase B) inhibitors. The established risk signature based on CIRGs can not only well predict the prognosis of HCC patients but is also promising in evaluating TMB and treatment response to immunotherapy, targeted therapy and chemotherapy, which has the potential to assist in the clinical management of HCC.

Diagnostic Accuracy of Preoperative Radiologic Findings in Papillary Thyroid Microcarcinoma: Discrepancies with the Postoperative Pathologic Diagnosis and Implications for Clinical Outcomes.

The diagnostic accuracy of preoperative radiologic findings in predicting the tumor characteristics and clinical outcomes of papillary thyroid microcarcinoma (PTMC) was evaluated across all risk groups. In total, 939 PTMC patients, comprising both low-risk and non-low-risk groups, who underwent surgery were enrolled. The preoperative tumor size and lymph node metastasis (LNM) were evaluated by ultrasonography within 6 months before surgery and compared with the postoperative pathologic findings. Discrepancies between the preoperative and postoperative tumor sizes were analyzed, and clinical outcomes were assessed. The agreement rate between radiological and pathological tumor size was approximately 60%. Significant discrepancies were noted, including an increase in tumor size in 24.3% of cases. Notably, in 10.8% of patients, the postoperative tumor size exceeded 1 cm, despite being initially classified as 0.5 to 1.0 cm based on preoperative imaging. A postoperative tumor size >1 cm was associated with aggressive pathologic factors such as multiplicity, microscopic extrathyroidal extension, and LNM, as well as a higher risk of distant metastasis. In 30.1% of patients, LNM was diagnosed after surgery despite not being suspected before the procedure. This group was characterized by smaller metastatic foci and lower risks of distant metastasis or recurrence than patients with LNM detected both before and after surgery. Among all risk groups of PTMCs, a subset showed an increase in tumor size, reaching 1 cm after surgery. These cases require special consideration due to their association with adverse clinical outcomes, including an elevated risk of distant metastasis.

Evaluation of the knowledge, attitudes and behavior of healthcare workers concerning influenza vaccination in a training and research hospital in Türkiye

Introduction and aim. Although increasing vaccination rates among healthcare workers (HCWs) is crucial for protecting their own health and preventing the spread of infections to patients, vaccination rates remain low. The purpose of this study is to evaluate the knowledge, attitudes, and behavior of healthcare workers concerning seasonal influenza vaccination in a training and research hospital in Türkiye. Material and methods. This cross-sectional descriptive study was conducted among 364 healthcare workers working in a training and research hospital in Ankara, Türkiye. A face-to-face questionnaire was completed by selected participants that included questions about their sociodemographic characteristics, receiving seasonal influenza vaccination, reasons for not receiving vaccination, attitudes and behavior towards seasonal influenza vaccination recommendations for their surroundings, knowledge of who should get the vaccine, and their immunization history. Results. Among the participants, 58.5% stated that they had never received an influenza vaccination, 35.7% mentioned not receiving the regular influenza vaccination, and only 5.8% reported receiving the influenza vaccination regularly every year. Reasons for not getting vaccinated included not trusting the influenza vaccine’s protection (60.1%), not believing they are in the risk group (38.9%), and not finding a suitable time to get vaccinated (36.1%). A total of 57.1% of the healthcare workers recommended the influenza vaccine for their surroundings. Conclusion. Influenza vaccination rates among healthcare workers are quite low. To maximize influenza vaccine uptake, awareness programs are needed to correct the misconceptions health care workers have about the vaccine, and diverse strategies should be implemented to encourage them to get vaccinated, thereby promoting influenza vaccination.

ФАКТОРЫ РИСКА ПРЕЖДЕВРЕМЕННОГО СТАРЕНИЯ ЛИЦА У ЖЕНЩИН

Of course, aging is a normal physiological process of the body's extinction, while there are no unambiguously effective methods that completely stop it. However, premature aging in some ways goes beyond the norm, because with an increase in the quality and duration of life, people have a younger appearance than their ancestors at their same age. Most of all, the external signs of premature aging are expressed on the face, which is becoming a widespread problem, and a comprehensive study of this aspect is one of the burning issues of modern medical science. Goal. The study of recent studies highlighting the problem of premature aging, as well as exogenous and endogenous risk factors. The mechanisms of the development of premature aging have a multifactorial basis. The prerequisites for the development of premature aging of the face were studied, the most significant exogenous and endogenous factors that increase the risk of this pathology were considered; risk groups were identified. An analysis of past and current studies has shown that in order to predict and prevent premature aging, a variety of both conjugate and independent indicators should be taken into account. As a result of consideration of factors of various nature, unambiguous mechanisms of premature aging have not yet been established. In the future, it is necessary to study in depth the problem of early aging, as well as the relationship of all risk factors among themselves.

Характеристика перебігу епідемічного процесу скарлатини у сучасних умовах

S carlet fever is one of the most common nosological forms of group A streptococcal infection (SGA). In recent years, there has been an increase in the incidence of this infection in the countries of Europe and Asia, the USA and Canada. The analysis of professional publications of different countries of the world regarding the manifestations of the epidemic process of scarlet fever was carried out, as well as information on epidemiological studies conducted by the authors was provided. It has been established that children remain the leading risk group for scarlet fever, men are more often affected among adults, but the role of young women who care for children as a source of infection is increasing. The aerosol-aspiration mechanism of transmission of the causative agent of scarlet fever is realized by airborne and contact-household ways of its transmission. There is an intensification of the contact-household way of transmission of the pathogen. An atypical course of scarlet fever is observed with manifestations of co-infection, in particular, gastroenterocolitis, chicken pox and respiratory infections. A significant number of publications are devoted to the influence of environmental factors on the course of the epidemic process of scarlet fever. The authors note a direct correlation between the incidence of scarlet fever and atmospheric air pollutants, meteorological factors, as well as the influence of social and economic factors on the epidemic situation of this infection. Long-term use of antibiotics has contributed to the development of antibiotic resistance to the most common drugs, which prompts scientists to develop vaccines against iSGA. So, scarlet fever is characterized by widespread distribution, impression of mainly children, co-infection, atypical clinical course, especially in immunocompromised persons, and implementation of the contact-household way of transmission of the pathogen. The influence of social, natural and environmental factors on the course of the epidemic process of scarlet fever has been established, which is important to consider when conducting epidemiological surveillance of this infection. The introduction of vaccination against iSGA will contribute to the reduction of antibiotic resistance, which is currently a global problem for humanity. We consider it necessary to include scarlet fever and other iSGA in the list of infectious diseases subject to registration in Ukraine. Key words: scarlet fever, incidence, risk groups, ways of pathogen transmission, atypical course, co-infection, environmental factors, antibiotic resistance.

MINIMUM WAGE AND RETURNS TO THE LABOUR MARKET ACTIVITY

In recent years, the minimum wage in Poland has been increasing not only nominally but also in real terms. Observing these changes, we identify a research gap regarding the impact of the minimum wage on the intensity of labour market flows. While there is no clear-cut relationship, it is possible that such an impact exists and varies according to the demographic characteristics of the group being analysed. In this article, we examine four so-called risk groups: young people (up to 30 years old), older individuals (50 years and above), women, and people with low levels of education. These groups, being the most vulnerable, are likely to benefit the most from an increase in the minimum wage.

Factors Influencing Customers’ Bank Selection Decision in Azerbaijan

Background: This research investigates the determinants of bank selection criteria and their linkage to the common satisfaction level of the banks in Azerbaijan. Aim: The study is motivated to investigate the current situation, find critical points and main related factors, inform bank executives and appropriate staff about real tendencies during the crisis and pandemic period. Methods: It is based on 2 surveys of 162 and 352 respondents respectively of different private and state-owned commercial banks. 13 main different factors for bank selection and 16 factors for credit cards usage were selected for better and proper analysis. Results: The findings of the study reveal that speed and quality of service, proven and strong shareholders, innovativeness and variety of services (credit cards), ATM network and accessibility, respect and friendliness staff, brand name at the market, and low interest rate on loans are the most important influencing factors for customers during the bank selection decision, while the other factors received the less rating, however, this does not mean that they are not important at all. The research found some similarities with the other research in different countries. The study could be used by banks and as the starting point for the next similar studies in the country. The findings of the second survey reveal that Risk and Security group has significant impact to the usage of credit cards while the other parameters don’t have such evidence.

IMPAIRED GAIT AND BALANCE DISORDERS AS RISK MARKERS FOR FALLS IN CHRONIC CEREBRAL ISCHEMIA

The main clinical syndromes of chronic cerebral ischemia (CCI) are impaired gait and balance disorders, which increase risks for falls. The objective of the study is to analyze correlation between impaired gait and postural instability to determine risk markers for falls in CCI patients. Materials and Methods. We examined 104 CCI patients (15 men and 89 women, median age 70 (63; 76) years). The patients did not have significant functional limitations in daily life (modified Rankin scale, 0–2 points). Thirteen patients (13 %) had a history of acute cerebrovascular accidents, thirty-seven patients (36 %) had a history of falls. Moderate cognitive impairment was detected in 53 patients (51 %). Impaired gait and balance disorders were assessed according to Tinetti test, Berg balance scale, and stabilometric platform. Statistica 13.0, SPSS 22 was used for statistical data processing. Results. According to the Tinetti test, impaired gait was detected in 101 patients (97 %), balance disorders were found in 32 patients (31 %). According to the Berg balance scale, most patients had a low risk for falls. Stabilometry showed a decrease in the limits of stability, mainly forward. Discriminant analysis revealed that significant predictors of falls in CCI patients are the “forward” limit of stability (&lt;59 points), female gender, age (&gt;67 y.o.), depression (&gt;9 points, HADS), sway index (eyes closed) in the clinical test for sensory integration and balance (&gt;0.855), balance score for the Tinetti test (&lt;15 points), and a history of acute cerebrovascular accident. Conclusion. Stabilometry along with clinical assessment can improve the effectiveness of determining the risk group for falls in CCI patients.

The Effect of Oral Care Protocols on Mucositis in Pediatric Cancer Patients: A Randomized Controlled Trial

Background/Aims: Standard oral care protocols can reduce the incidence of mucositis. This study aimed to evaluate the effect of the "Oral Care Protocol" containing sodium bicarbonate or saline on mucositis development, degree, and duration in pediatric cancer patients. Methods: This study is a blind, parallel trial design, randomized controlled study. Patients (n = 43) who received inpatient chemotherapy treatment for more than three days at the Pediatric Hematology and Oncology Unit were included. The oral care protocol with saline was given to the patients in the control group (n = 22), and the oral care protocol with sodium bicarbonate was given to the patients in the study group (n = 21). The primary outcome was the development of mucositis. The secondary outcomes were mucositis degree, patient data at the time of mucositis development, and the duration of mucositis. The characteristics of the patients in the study and control groups and the data of patients with and without mucositis were compared with Fisher's exact test, t-test, and chi-square analysis. Results: No statistically significant difference was found between the study and control groups in terms of mean age, gender, diagnosis, relapse status, treatment stage, risk group, and treatment protocols. Mucositis developed in 18.2% of the patients in the control group and 9.5% of the patients in the study group. No statistically significant difference was found in terms of mucositis development, degree, and duration. Conclusions: The oral care protocol with sodium bicarbonate can be used to prevent mucositis in pediatric cancer patients. ClinicalTrials.gov Identifier: NCTXXX.

Study of gene polymorphisms in Toll-like receptor 2 in patients with acute lymphoblastic leukemia

ObjectivesAcute Lymphoblastic Leukemia (ALL) is a multifactorial disease that results from the interaction between multiple genetic factors. ALL is characterized by uncontrolled production of hematopoietic precursor cells of the lymphoid progenitors within the bone marrow. The development of hematological malignancies has been associated with malignant-like cells that express low levels of immunogenic surface molecules, thus, facilitating their escape from cellular antineoplastic immune responses. This risk may be partly influenced by variations in polymorphic genes that control immune function and regulation. Toll-like receptors (TLRs) are well known pattern recognition receptors playing key role in innate immune response. Abnormal expression and dysregulation of TLRs will provide an opportunity for cancer cells to escape from the immune system and enhance their proliferation and angiogenesis. Toll-like receptor 2 (TLR2) play an essential role in innate immunity. Single nucleotide polymorphisms (SNPs) are present in a number of TLR genes and have been associated with various disorders. MethodsIn this study, 265 subjects have been divided into two groups included 150 patients with ALL and115 healthy volunteers. All subjects were genotyped using TaqMan PCR techniques. In total, Five SNPs were statistically evaluated in the TLR2 (rs1898830 A/G, rs3804099 T/C, rs3804100 T/C, rs1339 T/C, and rs1337 C/G), which may influence the susceptibility of ALL. Minor allele frequency and genotype distribution were compared across the study groups, and the relative risk and differences between patients and controls were estimated. Moreover, the mRNA expression level was evaluated in patients with ALL and the matched healthy individuals by Real-Time Quantitative Reverse Transcription PCR (qRT-PCR). ResultsTLR2 rs1898830 A/G; rs3804099 T/C; rs3804100 T/C; rs1339 T/C, were significantly decrease the risk in our population, overall and for certain subtypes and ALL samples exhibited significant increase in the mRNA levels of TLR2. ConclusionsThis study shows that TLR2 could be an independent prognostic factor of ALL risks in the Saudi population. Suggesting that genetic variation in genes associated with an immune response may be important in the etiology of ALL. In addition, the results herein revealed that TLR2 overexpression is associated with ALL and has diverse biological significance in the context of the complex relationship between inflammation and cancer development. Therefore, these data could open further studies to explore the possible clinical relevance of TLRs as pathological markers for Leukemia and enhance the strategies regarding hematological malignancies prevention based on their gene expression.
