Challenging the Practice of Administrative Detention for Stateless Persons in South Africa
Authors:   University of Cape Town, Khan Fatima
Published: December 2022

In South Africa section 41 of the Immigration Act requires any person approached on reasonable grounds by a police or immigration officer to identify themselves either as a citizen or as a person lawfully present in the Republic. Anyone unable to identify themselves as persons lawfully in South Africa will be deemed to be illegally present and hence subject to an arrest, detention, and possible deportation. This detention can go on for an initial period of 120 days. This “unlawful” status automatically entitles immigration officials to arrest and detain such persons, but with the caveat that if such persons express an intention to apply for refugee status their asylum application must be permitted and facilitated. Stateless persons are, by definition, unable to demonstrate their legal presence or provide a valid identity document. They would therefore be deemed to be unlawfully present and therefore detained. This section of the Immigration Act is especially prejudicial to stateless persons since South Africa has no status determination procedure for stateless persons. This paper intends to demonstrate the unlawfulness of the laws regarding the immigration detention of stateless persons and whether there is an alternative approach or a remedy that could be implemented for stateless persons arrested without the means to identify themselves in South Africa.

Published: December 2022

Since the beginning of the COVID-19 pandemic, many researchers have been interested in studying attitudes and behaviors in relation to vaccination, highlighting, through data, the so-called “vaccination hesitancy” (VH) phenomenon. Our aim was to investigate emotional states associated with the fourth dose of the anti-COVID-19 vaccine in individuals from the over 60-year-old and fragile patient category and to compare them with data that were previously recorded when the first vaccine doses were administered. The online questionnaire was created ad hoc and includes different sections: socio-personal data and the State-Trait Anxiety Inventory (STAI-Y) were used to detect the level of the state of anxiety, understood as a feeling of insecurity and helplessness in the face of perceived damage that can lead to worry or to flight and avoidance. The total sample consisted of 57 participants (61.4% M; mean age 67.23; SD= 6.73). Differences in emotional states in relation to vaccination emerged between Group I and Group IV in which the former were more worried and indecisive, while the latter, although nervous, felt more comfortable. Overall, trust in science appears to be a key determinant of vaccination intention. Additional strategies promoting healthy behavior are needed.

Published: December 2022

This paper uses data collected for an MA Thesis on the effectiveness of Border Security Governance in Preventing Crimes in Nimule Border Post South Sudan. The study assessed the nature of existing border security models at Nimule Border Post –South Sudan; to assessed the influence of administrative structures on border security at Nimule Border Post –South Sudan, established the effect of resource allocation on the quality of border security at Nimule Border Post –South Sudan, and finally determined law enforcement officers perceptions on best practices for border security governance at Nimule Border Post –South Sudan. This study was guided by two theories; The Contingency Theory and The Governance Theory. The study use a Descriptive Research Survey Design to investigate the problem under the study. Questionnaires were used to collect data from 75 senior members of the police and 10 Key Informants. Key informants guide was used to collect qualitative data from the Key Informants. Data was analysed with the aid of Statistical Package for Social Sciences (SPSS) and the results presented using tables, bar graphs and pie charts. According to this study the existing border security model is only composed of the local police. This is inconsistent with the new international security model that require a coordinated multipronged approach by other public agencies. This explains the runaway insecurity prevalent in south Sudan and worse in areas around Nimule border itself.  This administrative structure is organized in para- military style that limit and affect decision making of street officers at the Nimule border and characteristically discouraged free hand in operational contexts thus stifled security operations at the Nimule border. The study also established allocation of very scanty resources that did not support adoption of modern state of the arts border security technology at the Nimule border. According to this study law enforcement perceptions sought for the establishment of;  joint border crossing points, international cooperation, border community policing programs, establishment of border communities in border security management and coordinated cross-border patrols and multiagency operations. As a policy matter, the government should bench mark with developed countries of best border security model which requires a coordinated multipronged approach by other public agencies and conform to it if she is to cut the problem of border insecurity to the nib. Further, decentralize and demilitarize the administrative structure which are a characteristic of hierarchical leadership structures and strict command and give officers on the street a free hand in decision making at the Nimule Border.
Interaction between surfactants of different classes and nanofiltration membranes
Authors: Nunes Roberta Frinhani , Conceição Ferraz Helen , De Araujo Kronemberger Frederico
Published: December 2022

The presence of surfactants in aquatic environments may alter the water quality parameters. Nanofiltration is a promising technique that can separate surfactants from water with high rejections. Nevertheless, negative charges on nanofiltration membranes could facilitate the occurrence of electrostatic interactions between the charged surfactants and the surface of these membranes, increasing the membrane-fouling tendency. In this work, the interaction of surfactants commonly found in residential laundry wastewater with membranes used in nanofiltration was investigated. For this purpose, the surface, and transport properties of four commercial membranes were analyzed. The zeta potential of the NF90 membrane in the presence of individual and mixture of surfactants was performed to evaluate the effect of adsorption of these surfactants on the performance of the membrane. Additionally, a central composite rotatable design (CCDR) and response surface model were applied to investigate the simultaneous effect of the initial concentration of CTAB and SDS ([CTAB + SDS]0) and pH on the NF90 permeate fluxes and rejections. It was shown that surfactant adsorption varies with the type of surfactant and membrane. Moreover, adsorption played an important role in NF90 membrane fouling, mainly for the cationic surfactant in individual solutions and in the mixture of surfactants. Besides adsorption, pore blocking may have affected the performance of nanofiltration for higher concentrations of surfactants. Finally, by the application of the central composite rotatable design (CCDR), it was possible to find the best conditions of pH and initial concentration of surfactants for achieving higher fluxes and rejections by the NF90 membrane.

Published: December 2022

Objectives

The incidence of congenital neuroblastoma has increased in the recent years. The purpose of this study was to describe the clinical and biochemical characteristics of cases of congenital neuroblastoma diagnosed in our center.

Case presentation

We report three cases of congenital neuroblastoma diagnosed in our hospital. In two, diagnosis was made prenatally, whereas the other case was detected in the immediate neonatal period. In the three cases, neuroblastoma was located in the abdominal region and exhibited elevated concentrations of catecholamines or their metabolites in single voided urine samples. Two tumors were classified as stage M, and one as stage L2. The N-MYC oncogen was not amplified in any of the cases studied. Histopathological analysis was favorable in the three cases. The tumor was resected in two patients. The three received chemotherapy.

Conclusions

The measurement of catecholamines and their metabolites is essential in the diagnosis of neuroblastoma. When 24 h urine cannot be collected, single voided urine can be used to calculate the index based on creatinine concentrations.

Authors: Yang Meng , Zeng Changyu , Gong Zhongcheng , Shao Bo , Liu Gaocheng , Bao Xuying , Nie Bin
Published: December 2022

The present study involved building a model of immune-related genes (IRGs) that can predict the survival outcomes of tongue squamous cell carcinoma (TSCC). Using the TCGA database, we collected the gene expression profiles of patients with TSCC and analyzed the differences in IRGs obtained from the ImmPort database. Subsequently, we constructed a predictive model. Transcription factors and differentially expressed IRGs can be used to construct TSCC regulatory network. CIBERSORT tool was used to analyze the relative proportion of 22 tumor-infiltrating immune cells in TSCC samples. Finally, a prognostic model is constructed. We established an IRG model formed by seven genes. The receiver operating characteristic value of the prognostic model based on IRGs is 0.739. After the analysis of the correlation between IRGs and clinical and pathological conditions, we found that Gast was related to grade, IRF9, LTB, and T stage. Among the 22 tumor-infiltrating immune cells, the resting natural killer (NK) cells were found to be related to the 5-year survival rate. This study constructed a prognostic model formed by seven IRGs and discussed the tumor-infiltrating immune cells, which are related to the survival outcome, reflecting the potential regulatory role of TSCC tumor immune microenvironment that could potentially promote individualized treatment.
Relationship between platelet activation markers and spontaneous abortion: A meta-analysis
Authors: Gao Hua , Ma Hui-Juan , Li Ying-Jia , Li Yun , Zhang Ji-Rong
Published: December 2022

Numerous studies have indicated that mean platelet volume (MPV) and platelet distribution width (PDW) were correlated with spontaneous abortion (SAB), but the results were contradictory. Hence, we performed a meta-analysis to assess the association of MPV and PDW with SAB. We systematically searched on China National Knowledge Internet, PubMed, and Embase up to May 2022 to retrieve eligible studies. The synthesized standard mean difference (SMD) with a 95% confidence interval (CI) was used to evaluate the correlation of MPV and PDW with SAB. A total of 20 studies were finally included in this meta-analysis. The pooled analysis results showed that PDW was markedly increased in patients with SAB versus women with a healthy pregnancy (SMD = 1.03; 95% CI: 0.51–1.54; p = 0.0001), while there were no significant differences in MPV between women with SAB and those with healthy pregnancy (SMD = 0.19; 95% CI: −0.26 to 0.65; p = 0.40). Therefore, PDW may serve as a potential marker for predicting SAB. However, homogeneous and multiethnic studies with larger sample sizes are warranted to validate our findings due to several limitations in this meta-analysis.
The role of different “media diets” on the perception of immigration: Evidence from nine European countries
Authors: Terren Ludovic
Published: December 2022

A better understanding of media effects on immigration attitudes is crucial for policy development and innovation. While many studies have focused on immigration discourses or the salience of this issue in print media and broadcast TV, few have looked at how different “media diets” influence immigration attitudes. Using two-wave panel data composed of 14,480 observations (7,240 individuals) from nine EU countries, this article specifically analyses the role of online and social media news consumption as well as media diet diversity on Europeans’ perceptions of the economic and cultural impact of immigration. The results show that relying primarily on online or social media (compared to print newspapers) to get news, consuming news less frequently, or having a less diverse media diet all significantly and negatively influence people’s perceptions of the impact of immigration. Results and implications are discussed in light of today’s changing media landscape and news consumption habits.

Published: December 2022

Objectives

MEGDHEL [3-methylglutaconic aciduria (MEG), deafness (D), hepatopathy (H), encephalopathy (E), and Leigh-like disease (L)] syndrome is an autosomal recessive disorder caused by mutations in the serine active site-containing protein 1 (SERAC1) gene. MEGDHEL syndrome is clinically characterized by sensorineural hearing loss, encephalopathy, hepatopathy, 3-methylglutaconic aciduria, and Leigh-like lesions on cranial magnetic resonance imaging. During the neonatal period, it has been reported to present with hypoglycemia, hyperammonemia, impaired liver functions, cholestasis, metabolic acidosis, and sepsis-like clinical findings. However, clinical findings in the neonatal period were reported as a result of the retrospective evaluation of patients diagnosed at an older age. Herein we reported two cases diagnosed as MEGDHEL syndrome during neonatal period in two different clinics with sepsis-like findings, impaired liver functions, and ammonia levels high enough to require dialysis.

Case presentation

One of the cases was born 37 weeks of gestation with a birth weight of 2,060 g and initially presented with respiratory distress and feeding difficulties. The other case admitted to the neonatal intensive care unit had fed problems together with respiratory distress and circulatory failure within the first 24 h after initiation of parenteral nutrition.

Conclusions

MEGDHEL syndrome should be suspected in patients with sepsis-like clinical features and hyperammonemia.

Biology and life cycle Of Diatraea busckella (Lepidoptera: Crambidae) under simulated altitudinal profile in controlled conditions
Authors: Arbeláez Julián Andrés Valencia
Published: December 2022

Diatraea busckella (Lepidoptera: Crambidae), a sugarcane borer, was recently reported in Valle del Cauca, Caldas, and Risaralda in Colombia. This fact puts sugarcane (S. officinarum) producers in a critical situation. The insufficient knowledge about Diatraea species phenomenology, biology, and the life cycle feature under different climate scenarios does not let the experts relate (with certainty) the population explosion with climate offer changes. The work was carried out at the Center for Research and Breeding of Natural Enemies, located in the botanical garden of the University of Caldas at 5.0563885°3′23″ north latitude and −75.49416675°29′39″ west longitude, at an altitude of 2,160 m above the sea level and an average temperature of 14°C (Manizales, Caldas). To cope with the lack of bio-meteorological information, an experimental approach, based on the simulation of sugar cane production environments, was designed for obtaining the relationship between air temperature and the life cycle of the sugarcane borer. Growth chambers were used to simulate the air temperature of five ambients (10, 20, 24.7, 30, and 35°C). Under low latitude conditions (5°N), the referred temperatures corresponded to x, y, z, a, and b. The cycles were completed up to the first oviposition by females; in addition, the direct relationship between air temperature and the insect’s development, reproduction, and survival was verified. The number of days of the larval stage was 40 days DS ± 16.7 ± 2 days from larva to pupae and 6 ± 1 more to reach the adult stage under controlled conditions under five different temperatures (10, 20, 24.7, 30, and 35°C). In addition, significant differences were found in development time under controlled conditions (20, 24.7, and 30°C). Diatraea busckella can become a significant pest due to the positive response in development when environmental scenarios have to change, specifically the increase in temperature.

Published: December 2022

The study of radiation shielding properties for a material is an important part of research in scientific world. It is expressed in terms of the linear linear coefficients (LAC) which can also be used to obtain some other parameters. The gamma shielding properties of glass with addition of boron oxides in different amounts were studied, thereby obtaining linear attenuation coefficients (LAC), mean free path (mfp), Exposure Buildup factor (EBF) which were calculated using Phy-X/PSD code. It was found that increasing boron oxide content of 0, 2, 4, 6, 8 (w %) in glass increased the gamma attenuation coefficients.

BUCKWHEAT STARCH-MYRISTIC ACID COMPLEX FORMATION: EFFECT OF REACTION TEMPERATURE AND MYRISTIC ACID CONCENTRATION ON DIGESTIBILITY PROPERTIES
Authors: OSKAYBAS Betül , ÖZBEY Ayşe , AYDEMİR Levent Yurdaer , KAHRAMAN Kevser
Published: December 2022

This study aimed to investigate the effect of different reaction conditions on the digestibility properties of buckwheat starch-myristic acid complex samples produced using different myristic acid concentrations and different reaction temperatures. Response Surface Methodology was used to investigate the effect of reaction temperature (60-90°C) and fatty acid concentrations (0.1-0.8 mmoL/g) on digestibility properties. Resistant starch (RS) contents of samples increased with an increase in reaction temperature. The reaction temperature affected the rapidly digestible starch (RDS) and slowly digestible starch (SDS) content of samples. The highest RS content (32.57%) was obtained using 0.45 mmoL/g myristic acid at 90°C. The F, p (<0.05), and R2 values indicated that the selected models were significant for the digestibility properties of samples. The complex formation of buckwheat starch with myristic acid seems promising to increase the RS content. Buckwheat appears to have the potential as an RS source, although the studies are quite new yet.

Published: December 2022

Purpose: Computer networks and the Internet are changing the way we communicate, learn, work, and even play. Conventional computer networks are not smart enough towards processes that contribute to improving online control transaction of services and demand for unlimited communication services. Hence, computer networking has to go smart.Methods: This paper explores the effect of different computer networking types - traditional computer networking (D0) and Software-Defined Networking (D1). The paper combined traditional computer networking (D0) with Software-Defined Network (D2) running applications (A1, A2, A3, A4 and A5) with the host sending 5 packets (P1, P2, P3, P4 and P5) across the networks emulated using Mininet network emulation to observe various performance parameters on the network.Result: It was observed that Application A1 recorded the highest bandwidth, throughput and latency. The least bandwidth, throughput and latency were observed in A4. The result showed that below 80% of the IPv4 packet size (65,507 bytes) of running application, the higher the bandwidth the higher the throughput. Also, the lower the latency the more statistically similar the jitter experienced. Packet P1 has the highest bandwidth and throughput usage with high latency. The results indicate that the higher the bandwidth and throughput, the higher the latency observed in the packet sent across the network. Traditional computer networking (D1) recorded the highest bandwidth and throughput with the highest jitter. The correlation result showed that the jitter decreases with increasing bandwidth and throughput.Novelty: This study provides information on traditional computer networking and Software-Defined Networking. The result validates studies that observed significant F-value and stability in the SDN application-awareness experiment.

Published: December 2022

Purpose: A remote visual monitoring system will be very helpful for chicken farmers to monitor their cages, that usually located away from their houses. This system needs adequate bandwidth in transmitting the video over the internet, which is usually very limited in urban areas. The main goal of this research is to develop an automatic chicken coop remote monitoring system and define the optimum video resolution to be transmitted. Methods: We used an 8 MP Raspberry Pi camera V2 to record the video and send the results to Google Drive by utilizing the GDrive API. Furthermore, a live streaming video from the chicken coop is accessible through a simple HTTP web page utilizing ngrok as a tunneling software so that the live streaming video can be publicly accessed from anywhere using a web browser. Three video resolutions of 640x480, 800x600, 1024x768 with 15 and 30 framerates were used in our experiments. Each scenario has a duration of five minutes and takes 12 times.Result: The experiment results showed, resolutions that provide a stable video recording and streaming are 640x480 and 800x600. The resulting system succeeded in performing live streaming along with the process of data acquisition. Value: The Google Drive infrastructure is used because of its popularity and convenience by people with limited digital literacy such as smallholder chicken farmers. Furthermore, the video produced by this system can be used in supporting research of chicken behavior pattern identification to build a system notification of an emergency situation in the cage.

Published: December 2022

The purpose of this study was to study the effect of the percentage of the addition of conductivity material in phosphorylation starch to modify GCE (glassy carbon electrode) for detection of Cr(VI). In this study, the technique used is DPV (Differential Pulse Voltammetry). The conductivity material used in this study is activated carbon and Fe3O4 nanoparticles. The method used is an optimization of conductivity material in phosphorylation starch and determination of the performance of the obtained sensor. The optimum percentage of conductivity materials, both activated carbon and Fe3O4 nanoparticles, in the phosphorylation starch matrix is 5%. The form of amorphous activated carbon and the structure trigonal of Fe3O4 nanoparticles affects the current of Cr(VI). The addition of conductive material increases the current of Cr(VI) and shifts the peak potential to the left. The performance of PSC1 sensor is a detection limit of 5,09 ppm and sensitivity of 0,2098 ppm/µA in the linear concentration range of 2,6 – 15,6 ppm. However,  the performance of PSN1 sensor is the detection limit of 3,48 ppm and sensitivity of 0,2120 ppm/µA in the linear concentration range of 2,6 – 18,2 ppm.

Published: December 2022

Heating in honey processing can inhibit fermentation, crystallization, and the growth of microorganisms, such as bacteria. However, the effect of the honey heating process on the properties of honey and its antibacterial activity has not been further studied. Therefore, in this study, the properties of honey of both Apis and Trigona species from Bogor, Kalimantan, Sulawesi, Sumatra, and Lombok, were tested. The properties of honey, including water content, acidity, reducing sugar, 5-hydroxymethylfurfural (HMF), and diastase enzyme activity, were tested at heating temperatures 50, 70, and 90 °C. The antibacterial activity was determined using the disc method against Escherichia coli and Staphylococcus aureus. The results showed that the average water content and acidity values decreased after heating. However, the values met the SNI quality requirements with a water content value of < 22% and the acidity value not exceeding 50 mL NaOH 0.1 N/kg in the Apis and Trigona types of honey. The reduced sugar content fluctuated after heating all samples, and the average HMF level of honey increased after heating. However, the activity of the diastase enzyme decreased, although the value was still within the SNI standard value. The selected honey samples of the Apis and Trigona types were active in inhibiting the growth of Staphylococcus aureus but were not active against Escherichia coli.

Authors: Charlena Charlena , Maddu Akhiruddin , Hidayat Tatang
Published: December 2022

Hydroxyapatite (HAp) is a major component of bones and teeth. HAp is widely used to repair, fill, extend, and reconstruct damaged bone tissue. HAp is used for bone and dental implants, so it is necessary to synthesize HAp. HAp synthesis can utilize green mussel shell waste as a calcium precursor. This research synthesized HAp from a green mussel shell using the sol-gel method. The controlled synthesis parameter was pH, and the variable being compared was the heating temperature at 900 and 1100 °C. The HAp products were characterized by an X-ray diffractometer (XRD), Fourier-transform infrared spectrophotometer, and scanning electron microscope. The results showed that HAp was formed at alkaline pH, namely at pH 11. The XRD pattern showed that Hap was formed along with type A apatite carbonate, octacalcium phosphate, α- and β-tricalcium phosphate. The crystallinity was increased by raising the temperature and prolonging the heating time. The quality of HAp will improve with increasing crystallinity, and increasing the temperature will also raise the amount of HAp formed.

Authors: Slepička Martin
Published: December 2022

The study deals with the medieval cult of the early medieval hermit and the Benedictine abbot St. Giles in the Bohemian lands from its earliest beginnings to the end of the Middle Ages. Saint Giles, living in the 7th and 8th centuries in the region of Septimania located in the south of modern‑day France, became one of the most popular Christian saints in the medieval Western and Central Europe due to his patronage. The study therefore seeks to create a comprehensive interpretation of the form of the St. Giles’s cult in the Bohemian lands in the Middle Ages. The historical research of the cult of St. Giles is carried out through a detailed analysis of the medieval narrative and material sources, iconography, legends and sources of Church‑administrative origin. The text presents, in detail and with the help of the analysis of relics, calendars and Church dedications, not only the spread of the St. Giles’s cult in the Bohemian lands in the 12th century, but also the close relationship of the Holy Roman Emperor Charles IV to the mentioned saint. The study also discusses the fine arts monuments and the cult of St. Giles as one of the Fourteen Holy Helpers at the end of the Middle Ages

By a broad-range PCR, we detected a novel herpesvirus (HV) in the specimen of a wels catfish (Silurus glanis) presenting disseminated, carp pox-like dermal lesions all over its body. The sequence analysis of the 463-bp PCR product from the viral DNA polymerase gene indicated the presence of a hitherto unknown virus, a putative member of the family Alloherpesviridae in the sample. Another PCR, targeting the terminase gene of fish HVs, provided an additional genomic fragment of over 1,000 bp. Surprisingly, the sequence of a co-amplified, off-target PCR product revealed its origin from a putative gene homologous to ORF87 and ORF45 of cyprinid HVs and anguillid herpesvirus 1 (AngHV-1), respectively. With specific primers, designed according to the genomic maps of the cyprinid and anguillid HVs, a genomic fragment of 15 kb was also amplified and sequenced by primer walking. In phylogeny inferences, based on several genes, the putative wels catfish HV clustered closest to various cyprinid HVs or to AngHV-1. The novel virus, named as silurid herpesvirus 2, represents a distinct species in the genus Cyprinivirus. However, its association with the skin disease remains unclear.

The article summarizes the literature on the use of N-acetylcysteine and its combination with 3% NaCl solution (FLU-ACYL broncho) in clinical practice. Studies show that N-acetylcysteine is currently effective in the treatment of respiratory diseases due to its multicomponent effects on the respiratory system and the immune system. Hypertonic (3%) NaCl solution potentiates the action of N-acetylcysteine by inhalation and allows to achieve good results in the treatment of acute and chronic respiratory diseases in the optimal time. One of the well-known in Ukraine products for fast and effective evacuation of viscous sputum is FLU-ACIL broncho, sterile solution for nebulizer and instillation. One 5 ml ampoule contains 300 mg of NAC, which has a mucolytic effect in direct contact with mucus, and 150 mg of hypertonic NaCl solution, which draws water from the intracellular space into the extracellular space by osmosis and increases the proportion of water in the bronchial secretion, dilutes it and thus facilitates its removal. The combination of NAC with hypertonic NaCl solution creates synergy and allows to obtain optimal treatment results with minimal side effects. This combination has mucolytic, anti-film, antiviral, antioxidant, anti-inflammatory and immunomodulatory effects, making it promising in a pandemic SARS-CoV-2.

Pediatric tuberculosis (TB) is a serious infectious disease that affects many children worldwide and is more likely to be extrapulmonary than adult TB. The purpose - to analyze the profile of drug resistance of Mycobacterium tuberculosis and clinical features of extrapulmonary resistant (EPR) TB among children from Lviv region, Ukraine. Materials and methods. We analyzed all cases of EPR TB (n=23) and extrapulmonary sensitive (EPS) TB (n=24) among 478 medical charts of children, who were hospitalized in the Lviv Anti-TB hospital during 2013-2020. Results. It was found out that EPR TB was diagnosed significantly more often at the age of 1 year and up to 3 years old than EPS TB and significantly less often - among children aged 4-7 years. The children with EPR TB were significantly more likely to live in rural areas and they were significantly more likely to be from families with less than 2 children, compared to EPS TB. The children with EPR TB were more often diagnosed with meningeal and central nervous system (CNS) TB, less often - with TB of the bones and joints, only they had TB of the intestine, compared to EPS TB. Miliary pulmonary TB and the predominance of bilateral process were more common at EPR TB. Among children with EPR TB, rifampicin-resistant TB was significantly more common found than the risk of multidrug-resistant TB (MDR-TB) and monoresistant TB. The resistance profile of MDR-TB showed that 17.4% are resistant to the combination of HR (H-isoniazid, R-rifampicin), 8.6% - to HRES (E-ethambutol, S-streptomycin), 4.3% - to НRS. Among 43.5% of children with EPR TB the contact with a TB patient was not established. At the same time, only a third of children who had came into contact with bacterial exсretors were under dispensary observation and only about 9% received chemoprophylaxis. Conclusions. In order to prevent the development of EPR TB, it is necessary to improve TB prevention measures among the most vulnerable segments of the population. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of all participating institutions. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

The purpose is to analyze the risk factors for functional gastrointestinal disorders (FGID) in children, which will prevent their development and optimize therapy. The article presents an analysis of the literature on risk factors for the most common disorders: functional dyspepsia and irritable bowel syndrome. Among all potential predictors of FGID, chronic psychological stress is the most significant. The main triggers for its occurrence are sleep disturbance, excessive mental stress, dissatisfaction with family relationships with friends and parents, abuse of gadgets, smartphones, etc. Among the predictors of FGID, scientists consider malnutrition, starting from an early age, namely artificial feeding, to be no less important. In older adults, excessive lipid intake, adherence to FODMAPs diets, and consumption of ultra-processed foods are considered risk factors for FGID. In addition, a violation of the diet, the use of cold dishes also contribute to the occurrence of dysfunctions of the gastrointestinal tract. An important aspect of studying risk factors for FGID is the level of physical activity of children, as well as their nutritional status. Functional gastrointestinal disorders are conditions characterized by recurrent abdominal pain not explained by structural or biochemical disorders. The interest in functional pathology is quite justified and understandable: despite the fact that functional diseases of the gastrointestinal tract do not pose an immediate threat to the patient's life, they significantly reduce its quality: they affect all segments of society, regardless of socioeconomic status, gender or race, violate the microclimate in the family, which leads to anxiety of the child and parents, form long-term consequences in the future, contribute to a long diagnostic search, repeated consultations, unjustified appointments and expenses. Such a subject of discussion cannot remain without research interest due to the fact that the identification of the main risk factors for FGID will prevent their development, improve the quality of life, reduce the time and cost of examining a patient, and optimize therapy.
