Background: Gestational Trophoblastic Diseases (GTD) is a group of interrelated heterogeneous disease of trophoblastic tissue resulting from abnormal fertilization, characterized by abnormal tissue proliferation. Characteristically, prognosis positively correlates with early diagnosis and treatment.
Objective: The objective was to determine the burden, clinical presentation, management and outcomesof GTD at Irrua Specialist Teaching Hospital, Irrua, Edo State, Nigeria.
Methodology: A five-year descriptive (retrospective) study of histologically confirmed cases of st th GTD managed in ISTH between 1 July, 2016 and 30 June, 2021 was undertaken. Inclusion criteria: patient that were management at the study site, histology confirmation and availability of the case-file for review. Women managed for other gynaecological disorders or those with suspected GTD but no histologic confirmation were excluded from the study. Statistical analysis was done using SPSS version 20.0 and the results were presented in tables.
Results: There were 21 cases of GTD and 4703 deliveries with an incidence of 4.5 per 1000 deliveries. The mean age of participants was 32.9±7.5 years. Partial mole was the commonest histologic type (47.4%), choriocarcinoma (31.6%), complete mole (10.5%), invasive mole and placenta site trophoblastic tumor-PSTT (5.3%) respectively. Abnormal vaginal bleeding was the commonest presenting symptom 89.5% (17/19); others were excessive vomiting 52.6% (10/19) and abdominal pain 36.8% (7/19 ). The treatment modalities included suction curettage (42.1%) , suction curettage and chemotherapy (36.8%), total abdominal hysterectomy and cytotoxic chemotherapy only (15.8%).Serum Beta hCG returned to normal within 4 weeks for molar pregnancy and an average of 6 months for choriocarinoma. Default rate from surveillance was 10/19 (52.6%) while two participants (10.5%) died as cases of choriocarcinoma with advanced disease from late presentation.
Conclusion: Abnormal vaginal bleeding was the commonest presentation of GTD with high default and mortality rates. Therefore, efforts should be geared towards education and awareness to improve early presentation, surveillance and prompt treatment.

Una de las principales preocupaciones en el manejo de la anestesia general es la presencia de aspiración pulmonar peri-operatoria, la cual es una entidad que se presenta en 1:350,000 casos; lo que estima una incidencia de 0.1-19% que llega a desencadenar distintas complicaciones pulmonares que puede representar una mortalidad superior al 9%. Las directrices en cuanto a la prevención de aspiración pulmonar peri-operatoria se centran en una serie de recomendaciones de ayuno preoperatorio. Perlas y cols. desarrollaron un método por el cual, a través de la identificación y medición del área transversal del antro gástrico por ultrasonido, se calcula por edad el volumen gástrico, así como se caracteriza su contenido en vació, liquido o sólido; para estadificar en estómago de bajo riesgo o en estómago de riesgo cuando el volumen por kilo supera los 1.5ml /kg del paciente o cuando independientemente del volumen se observa restos sólidos. Se presenta el caso de un paciente masculino de 62 años de edad quien cuenta con antecedentes de cardiopatía isquémica quien cuenta con uso de stent y medicación antiagregante plaquetaria, hipertensión arterial y alteraciones electrocardiográficas perioperatorias, así como ausencia de ayuno preoperatorio a quien se le diagnostica apendicitis aguda; se realiza evaluación del contenido gástrico preoperatorio con ultrasonido.

The review article reflects on Vladimír Havlík’s book Hierarchical Emergent Ontology and the Universal Principle of Emergence (Filosofia, 2021). It notes the key argumentative procedures and implications of the author’s arguments. It evaluates the various elements of hierarchical emergent ontology and compares them with classical proponents and critics of emergentism, especially Paul Humphreys and Jaegwon Kim. The study reconstructs Havlík’s universal principle of emergence and notes its application in selected scientific fields (fermions, cellular automata and neural networks). It takes a polemical approach to the advocated concept of scientific metaphysics.
Postcolonial Psyche in English Novels from India and Africa
Authors: Haileab Isaias 
Published: March 2023

Purpose: Postcolonial Themes in English Novels from India and Africa is a thematic analysis of four novels, two from India and two from Africa. The novels are: Anita Desai’s Cry the Peacock, Salman Rushdie’s Midnight’s Children, Chinua Achebe’s Things Fall Apart, and Ngugi Wa Thiongo’s Matigari. They represent the vast postcolonial writing which has emanated from these two lands as a result of the disaffection that indigenous writers felt that colonialism had exacted on their people, culture and literature. The novels stand out in their treatment of the postcolonial themes of conflicts between the colonial and the local, the past and the present, the traditional and the modern, the communal and the individual aspects of the European colonial legacy in both India and Africa. A study in Postcolonial English novels from India and Africa is important as it may unfold the comparative experience of the effect of colonial period and the literary reaction by English language novelists from these two lands, which were subject to more or less similar colonial master.
Findings: The study reveals that all the four novels share in common the strong postcolonial theme which is at the crux of everything that follow. The story of the coming and going of the colonial powers in India and Africa had left their mark and it was not naturally compatible to the peoples of the populace in these two environments that were both colonized by the British.
Methodology: This article is based on a textual analysis of primary and secondary materials. The primary materials were obtained from the four selected English novels from India and Africa: Anita Desai’s Cry the Peacock, Salman Rushdie’s Midnight’s Children, Chinua Achebe’s Things Fall Apart, and Ngugi Wa Thiongo’s Matigari. The secondary materials were obtained from various books and articles published on the novels and on the subject of discussion as well.

Authors: Mikhalchuk M. V. , Bryl A. A. 
Published: March 2023

Information on the peculiarities of contaminant elements accumulation by cultivated and wild-growing plants in the zone of influence of Belinvesttorg-Splav LLC (Beloozersk), whose emissions into the air contain hazardous pollutants, including (heavy metals) HM, is presented. Analysis of the degree of elements accumulation by agricultural plants was carried out in comparison with subregional background values and permissible levels of veterinary and sanitary rules for ensuring the safety of feed, feed additives and raw materials for the production of mixed feed. As the main criterion for assessing the degree of contamination of HM leaves of wild plants, indicators of their background concentrations, as well as world averages, were used.
The established aero lead pollution of cultivated agricultural plants in the sanitary protection zone of Belinvesttorg-
Splav LLC and in the adjacent lands repeatedly exceeds the background and sanitary-hygienic values. Among the wild
plant species studied the most sensitive indicators of aerogenic pollution are: among the woody plants – common pine
(needles), in the group of bushes and shrubs – white mistletoe and common raspberry, among herbaceous plants – dioica
nettle. Research results testify to the necessity of sanitary protection zone extension for Belinvesttorg-Splav LLC at least
up to 1000 m (especially – according to the rose of prevailing winds) and cessation of agricultural activities within it.

Purpose: The purpose of this study was to examine the differences in the levels of parental engagement in the academic activities of learners in government grant-aided secondary schools in Sheema District based on demographic characteristics.
Methodology: The study was quantitative in nature and employed cross-sectional survey design. Participants of the study included Senior 4 students as well as their parents and teachers selected using probability.
Findings: The results indicated a statistically significant difference among parents of different socioeconomic statuses in engagement in provision of basic needs (X2(4) = 30.994, p < .05), academic communication (X2(4) = 29.317, p < .05), academic decision making (X2(4) = 18.906, p = .001), infrastructure development and maintenance (X2(4) = 11.412, p = .022), provision of a conducive learning environment at home (X2(4) = 25.291, p < .05), and provision of adequate learning resources at home (X2(4) = 41.890, p < .05). Differences in parental engagement were statistically significant among parents of different educational levels in provision of learning materials (X2(4) = 27.901, p < .05). There was no statistically significant difference in parental engagement among parents with 1—2, 3—4, and 5 and above school-going dependents. Based on these results, It is argued that family socioeconomic status and level of education influence parents’ engagement in their children's learning and subsequent academic success.
Recommendation: Government and other key stakeholders to develop and implement policies that can increase parents’ socioeconomic status as well as educational attainment in order to engage more fully in the education of their children.
African Agency within Confucius Institutes? Challenges to equal cultural exchange between CIs and African host countries
Authors: Homawoo Wokedje , Conyers Sterling 
Published: March 2023

According to Okoth-Okombo, language policy and economic development in Africa play a significant role in ensuring effective participation of large sectors of society in development activities and the public platform.[1] During a time when Sino-African trade and cooperation is at an all-time high, Confucius Institutes (CIs) have become important social funnels to signal cultural interdependency, while sensitizing the incumbent African workforce to the Chinese language and culture that awaits them within the new world order. Between the possibility of employment in increasingly numerous, African-based Chinese business ventures or the possibility to travel to China for further education, understanding the Chinese perspective has become more important than ever.

O paracetamol é comercializado desde a década de 1950, sendo um medicamento de amplo acesso a população por não precisar de prescrição médica, ser de baixo custo e por ter ampla distribuição, além de apresentar de média analgesia, alta ação antipirética e baixa ação anti-inflamatória se comparados a outros medicamentos de mesma classe. Embora ele seja considerado seguro em doses terapêuticas, as superdoses podem cursar com lesão hepática grave. Nesse contexto, a presente revisão visa evidenciar os principais fatores que predispõem a hepatotoxicidade do paracetamol, bem como mostrar os seus mecanismos de hepatotoxicidade. Entende-se que o paracetamol é um dos medicamentos mais utilizados de maneira indiscriminada pela população mundial tendo como consequências elevados índices de automedicação. Dessa forma, esse fármaco em doses altas e repetidas exerce um papel tóxico ao organismo, como pode ser percebido por meio de experimentos in vitro, os quais atestaram o seu potencial de esgotamento de glutationa que incapacitam o organismo de realizar a desintoxicação. Diante disso, como o fígado é o principal órgão que metaboliza o paracetamol, a superdosagem de tal medicamento acarreta lesões hepáticas de três maneiras, tais como overdose, oxidação da CYP450 e depleção dos hepatócitos. Contudo, observa-se que a overdose é o fator de toxicidade mais comum devido ao envenenamento recorrente, uma vez que não exclui uma faixa etária específica, atingindo tanto crianças quanto idosos.

O objetivo desta obra foi analisar os resultados do Teste de Aptidão Física (TAF) da Polícia Militar do Estado do Paraná após as alterações dos índices estabelecidos pela Portaria do Comando-Geral nº 384 de 2022. O estudo envolveu pesquisas bibliográficas para desenvolvimento de revisão de literatura e análise dos resultados de desempenho dos militares considerados aptos e inaptos no TAF. Na pesquisa foram analisados os resultados dos TAF’s da Comissão de Promoção de Praças de 2022. Dessa forma, os testes realizados de janeiro a agosto, foram anteriormente a modificação dos índices, e os resultados de setembro a dezembro, foram executados já com as alterações. A análise dos resultados apontou que, nos meses de janeiro a abril de 2022, 1873 militares realizaram o TAF, onde 1763 foram aptos, 94,12% e 110 inaptos, 5,87%. Nos meses de maio a agosto de 2022, 1275 militares realizaram o TAF, sendo 1180 aptos, 92,47% e 95 inaptos 7,44%. Importante destacar, que após a alteração dos índices, 1564 militares realizaram o TAF, sendo 1282 aptos, 81,96% e 282 inaptos, 18,04%. Além disso, também foi verificado que dos 282 militares inaptos nos meses de setembro a dezembro de 2022, apenas 7 militares foram inaptos no teste de Shuttle Run, 169 inaptos no teste de membros superiores e 144 na corrida de 12min. Portanto, constatou-se que após a alteração dos índices, o percentual de inaptos aumentou consideravelmente, sendo possível verificar que a maior inaptidçao ocorreu na prova de membros superiores, (Tração na Barra, Apoio de braço e Isometria).

During transfusion, components of blood including red blood cells, platelets and plasma are directly administered into the recipient to treat conditions such as anaemia and haemostatic deficiencies. In most cases, effective blood transfusions will positively impact patient prognosis. Red blood cell abnormalities greatly impact on the effectiveness of blood transfusion. This is because the efficacy of a red blood cell unit depends on the amount of blood delivered, the quality of cells and the life span of a given unit. The aim of this study was to establish the occurrence of red cell abnormalities in donor blood. This descriptive cross-sectional study was done at the regional blood transfusion centre, Mombasa and at the Technical University of Mombasa, Kenya. Consecutive blood samples were analyzed for selected red cell parameters. A total of 676 samples were analyzed. The study found that 31.07 % of the donor samples had one or more of the abnormalities assayed. There was a significant variation (t - 0.03, CI 95%) in the total red blood cell count. A significant Pearson’s positive correlation was realized between the osmotic fragility and haemoglobin concentration (r = 0.195; p < 0.001). This shows that a significant proportion of donated red blood cells in the donor pool had intrinsic or extrinsic abnormalities. There is therefore need to develop strategies that may better help to filter out these abnormalities as well as investigate the effect of such abnormalities to the recipient.

Jalan merupakan prasarana transportasi darat yang memiliki peranan penting pada sektor perhubungan darat, yang mendukung kesinambungan distribusi barang dan jasa untuk mendorong pertumbuhan ekonomi disuatu daerah. Mengingat daerah tersebut merupakan kawasan industri.Ruas jalan raya BTS Kota Lhokseumawe – Aceh Utara sepanjang 2,00 km mengalami kerusakan yang cukup signifikan. Oleh sebab itu dibutuhkan penelitian untuk mengetahui kondisi permukaan jalan dengan melakukan pengamatan secara visual. Penelitian ini bertujuan untuk mengetahui jenis dan tingkat kerusakan pada permukaan jalan dan mengetahui nilai kondisi kerusakan perkerasan jalan. Metode yang digunakan dalam penelitian ini yaitu metode PCI (Pavement Condition Index). Prosedur analisa data metode PCI ialah dengan menetapkan deduct value (m), menentukan CDV maksimum (Corrected deduct value), kemudian metode PCI merangking kondisi perkerasan dari nilai 0 hingga 100.Berdasarkan hasil penelitian didapatkan jenis kerusakan yang dapat ditemukan pada ruas Jalan BTS Kota Lhokseumawe - Aceh Utara yaitu kerusakan Lubang (Pothole), Retak Kulit Buaya (Alligator Cracking), Alur (Rutting), Retak Memanjang (Longitudinal Cracks), Pelepasan Butir (Raveling), dan Amblas (Depression). Dari sepanjang 2,00 km kerusakan yang sering dijumpai adalah Retak Kulit Buaya (Alligator Cracking), dengan total kerusakan 46, di ikuti kerusakan Pelepasan Butir (raveling) total kerusakan 22. Amblas (depression) total kerusakan 18. Lubang (Pothole) total kerusakan 16. Alur (Rutting) total kerusakan 9. Retak Memanjang (Longitudinal Cracks) total kerusakan 14. Jumlah total kerusakan dari 6 jenis kerusakan tersebut adalah 79 titik. Berdasarkan rekomendasi dari metode PCI (Pavement Condition Index) diperoleh kondisi kerusakan rata-rata ruas Jalan BTS Kota Lhokseumawe - Aceh Utara adalah sebesar 38,41% (jelek). Prioritas penanganan yang tepat dilakukan setelah mengetahui nilai PCI sebesar 38,41% yaitu perbaikan peningkatan jalan dan melakukan peninjauan kembali terhadap daya dukung tanah dasar.
