Aim: to evaluate the relevance of ultrasound markers in the first trimester of pregnancy for predicting twin-to-twin transfusion syndrome (TTTS) in monochorionic twins. Patients and Methods: this prospective study was conducted from January 2016 to September 2022 and involved 178 women with monochorionic diamniotic twins in the first trimester (11+0–14+0 weeks) who underwent ultrasound once every 2 weeks. Group 1 included women who were later diagnosed with TTTS (n=68). Group 2 included women without TTTS (n=110). Results: in women who later developed TTTS, a significant increase in the discordance of the nuchal translucency (NT) thickness (p=0.036), increase in the pulsatile index (PI) of blood flow in the ductus venosus in one fetus higher than normative (p=0.036), a significant difference in the difference in the crown-rump length (CRL) (p=0.046), large arterial anastomosis in the placenta with predominant signal on one side of the isoline, and chorion previa (CP) (p=0.012) were reported. The difference in isovolumic relaxation time (IVRT) in the first trimester was more than 9 (6–11) ms in the TTTS group and 5 (4–9) ms in the non-TTTS group. However, this difference was insignificant (p=0.06). A prognostic model of TTTS was built based on ultrasound signs (NT thickness, CRL, IVRT, ductus venosus PI) using logistic regression. Conclusion: our study revealed risk factors for TTTS at the end of the first trimester in monochorionic twins. However, these risk factors require further evaluation in a large prospective case series of monochorionic twins. A method for predicting severe complications of monochorionic twins during early pregnancy provides an additional option for stratifying patients. KEYWORDS: multiple pregnancy, monochorionic twins, twin-to-twin transfusion syndrome, first trimester ultrasound markers, nuchal translucency thickness, crown rump length, ductus venosus pulsatility index, placental anastomosis, isovolumic relaxation time.

Published: October 2023

Aim: to present a medical and social portrait of an expectant mother living in a metropolis. Patients and Methods: 400 expectant mothers underwent a sociological survey, which included several blocks of closed and open questions covering a wide range of life activities in expectant mothers who sought medical help on an outpatient basis in the profile "Obstetrics and Gynecology". Results: according to the data obtained, the portrait of the modern expectant mother in the metropolis is: 30.5 years old; officially married; has her first sexual experience before adulthood; higher or incomplete higher education; actively participates in public life; family income level is approx. 50 thousand rubles per person; leads a healthy lifestyle; uses contraceptives for protection from an unwanted pregnancy; plans to have two children. Conclusion: the following obtained data showed the need for extensive information and preventive activities in the medical care provision (according to the profile «Obstetrics and Gynecology») in outpatient settings which can bring enrichment knowledge and communication skills for medical specialists: increase in the expectant mother age up to 30 years, sexual relationship debut in half of women before adulthood, knowledge acquisition concerning STDs from medical professionals in only a third of the surveyed female patients, as well as the preference for barrier methods of contraception.

The article presents the author's experience concerning laparoscopic ovarian drilling (LOD) in women with infertility associated with polycystic ovary syndrome (PCOS). The study included 23 female patients aged 18–35 years with infertility associated with PCOS, who were treated with clomiphene citrate for 6 months without effect. All patients underwent LOD with electrocoagulation. The follow-up period after surgery was 3 years. Pregnancy occurred in 10 (43.5%) of the female patients within a year after the LOD, and in 13 (56.5%) — pregnancy occurred within 2–3 years. There was a difference in the pregnancy frequency during the year between female patients under 30 y.o. (9 (39.2%)) and over 30 y.o. (11 (47.8%)). Pregnancy occurred less frequently in patients over 30, however, due to the small number of patients, the presented results were not statistically significant. Thus, it requires further follow-up and confirmation of this conclusion. It was also revealed that the shorter the infertility duration, the greater the pregnancy likelihood after surgical treatment: pregnancy occurred in 9 (39.2%) female patients with infertility period of <3 years versus 1 (4.3%) female patient with infertility period of >3 years (RR 5.8, 95% CI 1.2–36.2). In conclusion, LOD can be used in female patients with resistance to clomiphene citrate. The ovulation restoration, and pregnancy and childbirth onset make LDL a possible alternative method of treatment with a lower risk of complications (ovarian hyperstimulation syndrome, multiple pregnancy). KEYWORDS: infertility, pregnancy, treatment, laparoscopic ovarian drilling, polycystic ovary syndrome, gonadotropin resistance.

Com-plexus: espacio y comunidad
Authors:   Facultad de Filosofía y Letras, Benemérita Universidad Autónoma de Puebla (BUAP), Romero Contreras Arturo
Published: October 2023

El presente texto avanza la tesis de la ontología exige un pensamiento de la comunidad y su relación con el espacio. Para ello se avanzan tres líneas de pensamiento. 1. Un pensamiento del ser debe poder conjugar un lado ontológico y otro ético-político al mismo tiempo, sin reducir o subordinar el uno al otro. Esto es lo que llamamos aquí “comunidad”, que su vez solo es posible fragmentando la unidad del origen. 2. La ontología de Heidegger ha resaltado el nexo esencial entre ser y tiempo, desarrollando una crítica a la filosofía de la presencia. Pero al pensar un origen fragmentado, distribuido, introducimos una dimensión espacial en el razonamiento ontológico. Hace falta entonces pensar el nexo entre ser y espacio. Un pensamiento del espacio puede desarrollar una conceptualidad a partir de la topología matemática. 3. La comunidad y el espacio exigen no sólo nuevas categorías sino también una lógica distinta (no-aristotélica), capaz de lidiar con la complejidad y la paradoja. Tomando en consideración los puntos anteriores se esboza un programa filosófico

This paper presents a comparative analysis of wastewater management practices in Myanmar’s major cities, Yangon and Mandalay, with a focus on drawing valuable lessons from Yangon’s experiences and proposing recommendations for the improvement of Mandalay’s domestic wastewater management, drawing insights from a SWOT analysis. Both cities are facing challenges due to rapid urbanization, leading to untreated discharge into the environment. The study identifies common challenges in both Yangon and Mandalay, such as limited treatment capacity, environmental concerns, and funding gaps. The decentralized-centralized strategy is a successful approach for Yangon even though the capacity is not high. Results showed that 17.5% of Decentralized Wastewater Treatment Systems (DEWATS) users were highly satisfied and 45% were somewhat satisfied. Yangon’s experience with centralized systems showed that it took several years to cover the entire city for treatment, resulting in issues to cover revenue expenditures. If Mandalay adopts a similar, it will likely encounter the same issues. A recommended approach would be to implement an integrated system with DEWATS, which offers a better solution. The recommendations for sustainable wastewater management in Mandalay include active stakeholders’ involvement in decision-making, promoting community participation, and providing training. Transparency and shared responsibility are crucial for success. Addressing membrane fouling, sludge disposal, and implementing monthly fees are essential for sustainable implementation. An integrated approach along with environmental and social impact assessments are necessary to develop a cost-effective and efficient wastewater treatment system while safeguarding public health and the environment. These insights offer broader implications, guiding developing countries towards more effective and environmentally responsible wastewater management practices.

Published: October 2023

The article deals with the creation of a geographic information system (GIS) for assessing the noise pollution of an urban area from road transport under various conditions. The factors that can influence traffic noise are studied. A measurement experiment was planned, and control points were selected and justified taking the following factors into account: traffic level, transport, traffic features, number of lanes, adjacent territory. A measurement experiment was carried out using a noise meter at selected points at different times on the territory of Vasilyevsky Island. All information about the points, including location, noise level readings and conditions, are systematized on the basis of GIS ArcGis Desktop. Two databases were compiled: the Monitor database contains general information and contains control points reflected on the map; the Analys database contains information about dependencies and factors. Based on the data obtained and their analysis, various factors were analyzed and thematic maps were constructed. These maps clearly show the impact of road transport on the pollution of urban areas under various conditions. The created geoinformation system makes it possible to identify the most dangerous areas in order to develop recommendations for preventing the negative effects of noise on the health and life of people and nature.

The paper is devoted to the formalization of sememethic components of presubject structure of information. It is based on the monograph «Philosophy of the name» by A. F. Losev [1] and presents the continuation of the phonetic components formalization [2]. The purpose of the article is to verify the conceptual basis of constructing the models of knowledge presentation in the systems of a natural language in accordance with the multi-level structure of information. Both in the present and in the previous [2] articles only 12 lower levels beginning from the phonetic components up to symbolone II are presented. Symbolone II completes the consideration and provides the unity of the symbolic components of the presubject information structure. The given model can be used in the computer linguistics and in the development of the processing systems of a natural language.

Authors:   Saint Petersburg Electrotechnical University, SPC «SES», Vorontsov A. G.
Published: October 2023

Mathematical and computer models of an asynchronized electromechanical insert in the power supply system of a metropolis are constructed. The work of two asynchronized generator-motors located on a common shaft, transistor active frequency converters in the excitation and start-up systems of the unit, as well as control devices is considered. For the electric power system, an analysis was made of the main operating modes of the plant with machines with a capacity of 200 MW. The modes of starting the unit, synchronizing it with two power lines, transferring power to the unit, transferring electricity from one network to another through a common shaft of machines, and reversing active power are analyzed. Some emergency operating modes of the system are considered. It is proposed to use the kinetic energy of an electric machine unit for uninterrupted power supply to loads in case of an emergency shutdown of one of the two sources of electricity in the power system.

La Hipertensión Arterial (HTA) es un factor de riesgo relevante de enfermedad cardiovascular. La prevalencia en pediatría ha ido en aumento, asociado al incremento de sobrepeso y obesidad infantil, entre otros factores. Un diagnóstico adecuado e intervención precoz son determinantes en la prevención de daño de órgano blanco. La Academia Americana de Pediatría recomienda realizar Monitorización Ambulatoria de Presión Arterial (MAPA) en pacientes pediátricos con sospecha o factores de riesgo de HTA para confirmar el diagnóstico y dirigir el tratamiento. Las nuevas recomendaciones recientemente publicadas simplifican la interpretación; se elimina la sobrecarga como determinante para la clasificación, quedando sólo 4 categorías diagnósticas de presión arterial: Normotensión, Hipertensión de Delantal Blanco, Hipertensión Enmascarada e Hipertensión Ambulatoria. Asimismo, cambian los valores de corte en adolescentes ≥ 13 años, usándose los valores de referencia de MAPA para adultos recomendados por la American Heart Association en 2017. Ambos cambios aumentan la sensibilidad de este examen para la detección de repercusión sistémica. En este artículo se actualiza el estudio y diagnóstico de la HTA basado en las guías de Monitorización Ambulatoria de Presión Arterial chilenas para pacientes pediátricos, con el objetivo de unificar criterios diagnósticos, mejorar su difusión y ampliar su cobertura nacional. Además, se aporta una actualización en relación a las distintas categorías ambulatorias de presión arterial, al daño de órgano blanco y recomendaciones para el correcto uso de esta herramienta diagnóstica, incluyendo sugerencias de informe.

The purpose of this research was to study the manufacture of milkfish and carrot sausages by treating the proportion of tapioca flour: taro starch and the addition of egg white on physicochemical and organoleptic properties. The use of taro starch is because contains amylose and amylopectin which can bind air more strongly and can make the texture more springy. Carrots are used for coloring sausages because they contain carotenoid compounds. Egg whites are used to increase protein levels. This study used a completely randomized design with two factors, namely the proportion of tapioca flour to taro starch (75:25; 50:50; 25:75) and the addition of egg white (3, 6, 9%). The results showed that the proportion of tapioca flour: taro starch and the addition of egg white had a significant effect on moisture and ash content. However, it did not significantly affect the levels of fat, protein, starch, emulsion stability, and hardness. The best treatment was obtained from the combination of the dimensions of the proportion of tapioca flour: taro starch (25: 75) and the addition of 9% egg white which obtained a moisture content of 72.69%; ash 2.45%; fat 2.31%; protein 12.16%; starch 7.14%; emulsion stability 99.06%; hardness 2.59 kg.m/s2; and hedonic color 3.76 (neutral); fragrance 4.00 (like); taste 4.28 (like); and texture 4.48 (like).

Avocado is a climacteric fruit, which is usually harvested when it is still unripe. One way to accelerate the maturity of climacteric fruit is by ripening. Ripening treatment with ethrel can accelerate fruit ripening. This study aims to determine the effect of proper ethrel concentration on the avocado ripening process. The experimental design used was RAL (Completely Randomized Design) 1 Factor with 5 treatments and 4 replications. The treatment consisted of P0 control without ethrel treatment, then added ethrel solution P1 = 0.25 ml/L, P2 = 0.50 ml/L, P3 = 0.75 ml/L and P4 = 1.00 ml/L. Variables observed included weight loss, color, texture/hardness, water content, total dissolved solids and fat content. The data obtained were analyzed for variance and if there were significant differences in the treatment then it was further tested with Duncan's test at the 5% level. Based on the results of research on adding the right ethrel solution to the avocado ripening process found in P4 with the addition of 1.00 ml/L ethrel with a fat content of 15.34%, water content 88.99%, total dissolved solids 2.10 mg/L, texture 968.85grf, color 80.44 and weight loss 10.51%.

Background: One of the leading causes of mortality and morbidity in under-5 children is Diarrhea. Malnutrition, in association with the diarrheal disease, affect children negatively. On 2018, Bangladesh saw massive influx Rohingya people with almost 29% under-5 children.
Objective: The purpose of the present study was to determine the prevalence of malnutrition among children admitted with acute diarrheal diseases at the Primary health Centers at Cox’s Bazar.
Methodology: This cross-sectional study was conducted among the diarrhea affected under-5 Rohingya children who reported to primary health centers at cox’s bazar. The study was conducted from January to December 2018. Primary caregiver of 276 respondents were interviewed, their hospital records were reviewed. Data were collected by face-toface interview using a semi-structured questionnaire.
Results: The majority (60.1%) of the participants were male. Only 2.9% of the participants reported passing of macroscopic blood in stool. Oral Rehydration Solution (ORS) was not taken by most of the participants (50.7%), prior to visit to the hospital. The mean (±SD) age was 18.54 (±12.44) months. Among the participants, 14.1% had severe underweight (<-3 WAZ score) and 27.2% had moderate underweight (-3 to <-2 WAZ score). No death was reported, and 97.1% were discharged with advice from the hospital. Statistically significant relationship was found between age of the participants and underweight (p<0.05) with a Moderate effect size (Φ=.21).
Conclusion: The study findings would be helpful to identify the need for raising awareness among Rohingya caregiver and help healthcare providers to become more cautious in treating diarrheal patients.

Authors: Akhter Sonia , Zihadi Md Asief Hossain , Rahman Md Habibur , Rahman Md Zillur
Published: October 2023

Background: Pneumonia in sheep is a complicated multicausal disease which affects the respiratory system causing increased morbidity and herd mortality rate. The members of Pasteurellaceae family are one of the prime causes of bacterial pneumonia in ruminants. Once infected by these organisms, antimicrobial therapy becomes obligatory. In Bangladesh, causation of pneumonic pasteurellosis and their antibiogram is unknown in sheep which insists the veterinarians to choose empirical antimicrobial therapy.
Objectives: This study was undertaken to identify multidrug resistant Pasteurella multocida and Mannheimia hemolytica in sheep suspected with pneumonia.
Methodology: The samples of nasal swab and the lungs were collected aseptically. After overnight incubation in Brain Heart Infusion broth, the samples were streaked onto 5.0% sheep Blood Agar to obtain pure colony with characteristic features which were subjected to biochemical tests, polymerase chain reaction (PCR), and antibiogram study against eight antibiotics. Results: A total number of 140 samples were collected of which 120 nasal swabs and 20 lungs were collected aseptically. In total, 16.7% pneumonia cases in sheep were found to be caused by Pasteurella species. Out of 140 samples, 43.57% (61/140) were positive for Mannheimia hemolytica (68.85%) and 19.67% for Pasteurella multocida. The mixed infection by both organisms was 11.48%. The Mannheimia hemolytica (MH) was predominant in lungs (100.0%) and nasal swab samples (18.3%) than Pasteurella multocida (PM) which were 15% and 7.5% respectively. All the isolates were found to be multi-drug resistant where resistance against Penicillin and Ampicillin was 100% for all isolates. The resistance of Mannheimia hemolytica and Pasteurella multocida towards sulfonamide, ceftriaxone, oxytetracycline, gentamicin, and streptomycin were 63.33%, 49.44%, 44.44%. 16.67%, 11.11% and 78.22%, 45.46%, 45.45%, 36.36%, 27.27% respectively. Among all antibiotics tested, Chloramphenicol stands out to be the most effective one (100% sensitive).
Conclusion: This study states the first molecular identification of Mannheimia hemolytica and Pasteurella multocida from sheep suspected with pneumonia in Bangladesh and their antibiogram pattern against commonly prescribed antimicrobials. Due to their commensalism nature and wide host coverage, these MDR pathogens warrant judicious use of antibiotics in small ruminants to reduce veterinary public health hazard.
