Introduction: The objective of this study is to determine the characteristics of the epidemic outbreak in the health zone of Dungu with low routine vaccination coverage of children aged 0 to 59 months in VAR, in order to contribute to the implementation specific strategies to prevent new outbreaks. Method: This is a cross-sectional and descriptive epidemiological study. It focused on an exhaustive evaluation of all cases of measles confirmed by epidemiological link declared in the Dungu health zone during the period from April to December 2019 and on the evaluation of the response implemented. A comprehensive literature review was conducted taking into account all confirmed measles cases from the period April to December 2019, residing in Dungu health zone and notified to the national health system report database. health information (SNIS) and data on the response to this epidemic. The information collected was entered on Epi Info in a mask designed for this purpose. Results: The results show that out of a total of 5616 children targeted for measles vaccination in the health zone in 2019, 2117 cases (38%) of measles were confirmed. But thanks to adequate case management and the implementation of sectoral responses, there were only 2.3% of deaths. 70% of cases were confirmed on the basis of the existence of an epidemiological link with one or more confirmed cases. Just over half of the measles cases were male, or 58%. The epidemic age peak is 13-24 months (67.4%), more than the majority of measles patients (78.9%) have never been vaccinated against measles. Only 446 measles patients, or 21%, received a dose of measles vaccine (VAR). None of the measles patients received 2 or more doses of VAR. The Moussa health area was most affected by measles, ie 38.5%, followed by Wandote 22.5% and Sambia 16.8%. Conclusion: In order to avoid such epidemics in the future, it is recommended to make parents aware of the interest of vaccination, to combine vaccination systematically with activities of vitamin A supplementation and deworming with mebendazole wormer, to organize national vaccination campaigns with the targeting of specific groups of children of Mbororo herders, children of gold miners, children from armed groups such as the LRA, children who live in areas where logging is carried out, to institute the second dose of vaccine in the school environment which makes it possible to catch up with children who have missed the first vaccination and also to correct primary vaccination failures in those who have been vaccinated.

Objectives: This work thematically x-rayed the Igbo society and its culture, the impact of colonialism in Africa, cultural and religious conflict in Chinua Achebe’s “Things Fall Apart”. The novel captures the spirit of the African society during the transitional period. It delineates the encounter between the culture of Igbo tribes and the British culture necessitated by colonialism. Achebe’s Things Fall Apart portrays the African culture, tradition, social life, rituals and religion as well as the role religion plays in shaping people’s mind and behavior. It examines the impact of western religion on Igbo society/Africans at large that were happy with their religion. It elucidates the peculiarities in Igbo culture and tradition, especially the beauties and wisdom of its art and institutions. Achebe uses the novel to correct the misrepresentation of African culture and religion in Europeans literatures. It criticizes certain aspect of the African cultures that are inhuman and exposes the religious and cultural conflict between the western and African. The novel reveals the benefits of western civilization in Africa and these valuable benefits they acquired made them handicapped to fight their colonizers. Achebe delineated the colonial influenced on the African culture and religion. It also portrays the exploitation of the colonial masters under the cover of religion. It elucidates how the Africans suffered and lost their cultures and values due to the external forces that were beyond their control.

Wormian bones, otherwise ‘Sutural’ bones, are accessory bones within or near cranial sutures. They are mostly found on lambdoid sutures and can be one or more in each suture. This study is aimed at examining the incidence and frequency of Wormian bones in the dry adult cadaveric skull in Rivers State, Nigeria. Forty-three (43) dry adult skulls were examined for the presence, number, and location of Wormian bone. Thirty-seven (37) of the skulls were from the osteological collections of the Department of Human Anatomy, Faculty of Basic Medical Sciences, College of Health Science, University of Port Harcourt, and six (6) from the osteological collections of the Department of Human Anatomy, Faculty of Basic Medical Sciences, College of Medical Sciences, Rivers State University. 13 (30.23%) of the calvarias had Wormian bones while sutural bones were absent in 30 (69.77%0). 8 (61.53%) calvarias with Wormian bones had sutural bones in the lambdoid suture; with 3 (23.08%) on the left arm and 5 (38.46%) on the right arm of the lambdoid suture. 2 (15.38%) of the calvarias with Wormian bone had sutural bone in the sagittal suture and 3 (23.08%) had Wormian bones in the lambda (Inca bone). The knowledge of incidence of Wormian bone and their calvaric distribution as described in this study is essentially useful to the Anatomist, Radiologist, Pediatrician, and Surgeon in their daily practice, as well as in forensic medicine.

We present a case of a 26-year-old female at 37 weeks of gestation with concomitant pituitary apoplexy and acute fatty liver complicated with disseminated intravascular coagulation, leading to foetus death and hemorrhagic shock secondary to a massive uterine haemorrhage which was successfully managed in Intensive Care Unit. To the best of our knowledge, this is the fourth case reported in the literature.

Background of the study: Erectile dysfunction may be responsible for a reasonable amount of male infertility. Erectile dysfunction can lead to male infertility. Male infertility is due to any problem in the male reproductive system including decreased sexual desire, barrenness, premature ejaculation, etc. Method: 20 male Wistar rats and 5 female Wistar rats were used for this study. Male animals were grouped into control, Viagra, high-dose Bay leaves, and low-dose Bay leaves. The extract was administered for 21 days. The animals were acclimatized for one week. Extracts were administered for three weeks. A sexual behavioural study was carried out on the animals in the dark for three days. 24 hours after the last day of the sexual behavioural study, the animals were sacrificed and the testes were harvested and sent for histological studies; semen was collected for semen analysis. Results: Data were expressed as mean ± SEM. The mean difference between the tested groups and the control was tested using a one-way ANOVA. Values were considered statistically significant when P is ≤ 0.05. Mount frequency increased significantly in high-dose groups of both premature plant and bay leaves treated animals. Conclusion: This implies that the plant extract used for the present study increases sexual function (libido and potency).

The free fibula flap has emerged as the preferred option for reconstructing defects in the mandible and maxilla. The method of implanting a fibula flap is nearly identical to that used on the original jawbone, but accessing the bone during surgery is the most challenging part. Previous reports discussed the use of dental implants following free flap tissue transfer. This review aims to discuss all the relevant trials discussing dental implants following free flap surgery.

Stock price index futures have long been viewed by experts and scholars as a risk-hedging trading tool that can help investors’ hedge risk and ensure the healthy and stable development of China's financial stock market. The asset underlying of stock price index futures is the stock price index. The CSI 300 stock index futures, a type of stock price index futures, were created on April 16, 2010, and its birth marked the official start of stock index futures trading in China. After the launch of CSI 300 stock index futures, the China Financial Futures Exchange launched (CFFEX) SSE 50 stock price index futures and CSI 500 stock price index futures one after another. The introduction of stock price index futures trading can bring about an impact on the volatility of the stock spot market to a certain extent and play a role in reducing volatility. The speed of transmission of stock index information to market participant decreases after the China Financial Futures Exchange restricts stock index futures trading. Based on the results that the coefficients of DF-DT, the cross term of the two dummy variables added to the GARCH model, have significant values and values less than zero, it can be analyzed that the restrictive measures taken by the China Financial Futures Exchange on stock index futures trading enhance the mitigating restrictive effect of the introduction of stock index futures trading in China on the volatility of the Chinese stock spot market.

The menace of cultism has eaten deep into the Nigerian Institution of higher learning especially in Rivers State and inspite of the jail term for airing members of a cult group caught by the authorities as proscribed in the Nigerian 1999 constitution as amended. This menace is still growing and gaining more grounds in the entire higher institutions on daily basis. Cultism constitutes a major social problem to the peace and harmony that ought to exist within the academic confines of Rivers State. Admittedly the menace have attracted so much tension and concerns of major stakeholders within and outside the educational system and it negative impact affects our universities in terms of disruption of academic calendar, vandalization of school facilities, loss of lives of both innocent and actual cult members within and outside the school environs as well as raping of students. Unfortunately, it has been reported that students who are from disorganized family background that fall prey of joining cult group either in their local environment or when they gain admission into higher institution. This however, is now seen as a very big problem that need immediate solution if the aims and objectives of educating the younger generation are to be actualized. Thus, it further indicates that some factors that motivate the emergence and sustenance of secret cult in the educational system are traceable to the faculty decadence of our immediate society, the parental or student background, the educational environment etc. This study therefore offer some policy recommendations that is needed if we are ready to curtail the activities of cultism in our society and within our educational institutions in Rivers State.

The aim was to study the epidemiological, clinical and therapeutic aspects of paraphimosis at the CSRéf of Markala. Patients and Methods: We conducted a prospective and descriptive study of five patients who had consulted for paraphimosis in the operating theatre of the Markala referral health centre from 1er January 2019 to 31 December 2021, i.e. a two-year period. Our study included all patients who consulted for paraphimosis at the CSRéf of Markala with a usable medical file. The criteria for non-inclusion were: Phimosis without other pathologies of the penis. The records were not usable, as this was a prospective study. Results: The frequency of paraphimosis was 2.1% out of 235 patients hospitalized and operated on at the CSRéf of Markala during the study period. Four of our patients had no particular medical or surgical history, but the oldest of our patients had already undergone a hernia repair and an appendectomy at the time ; the average age of our patients was 15.3 years, with extremes ranging from 3 years to 53 years . However, we note that there is no specific age of onset of paraphimosis The treatment received by all our patients was posthectomy. No major complication was noted in our patients, however we deplore a loss of sight in two of our patients for a long term follow-up in order to identify other unknown aspects in the management of paraphimosis. Conclusion: Paraphimosis is a true urological emergency that occurs in uncircumcised men when the foreskin is trapped behind the glans crown, which can lead to long-term strangulation of the glans and compromise its vascularity hence their immediate management paraphimosis.

Xi Jinping: The Governance of China (Volume III) profoundly answers important theoretical and practical questions about the development of the Communist Party of China and the country under the new historical conditions, and is a representative work of the current Chinese political literature, focusing on the governance concept and governing strategy of the new Central Committee of the Communist Party of China, in which various travel metaphors are used. This research makes a discourse analysis of travel metaphor to help study the translation strategies of the book.

This paper defines and assesses a market timing strategy for the Gulf Cooperation Council (GCC) stock indices, namely the Tadawul All Share Index, FTSE Abu Dhabi General Index, Qatar All Share Index and Qatar Al Rayan Islamic Index. The strategy intends to deliver a consistent reduction in volatility and better risk-adjusted performance. The present empirical study capitalises on the work by Colepand and Copeland (1999) on the US market, re-proposed recently by Bantwa (2020) on the Indian market, which resorts to implied volatility as the trigger to adjust the asset allocation. The strategy hereby proposed is modified considering the higher volatility of the GCC financial markets as well as its preeminent goal – risk-adjusted performance optimisation. Moreover, the implied volatility is unavailable for the GCC stock indices under assessment; therefore, it has been replaced with the forecasted volatility obtained through asymmetric GARCH models (GJR-GARCH), one for each stock index. The active strategy in question is backtested on both the conventional and Islamic stock indices to check whether it overperforms the passive strategy equally well on both types of indices. The empirical findings encourage the adoption of volatility-based market timing models in additional emerging markets and Islamic indices.

Residual soils are in the category of questionable soils which have been experienced in the arid and semi-arid climatic zones of the world. The conditions in these zones favour the development of most unsafe collapsible soils. At their dry natural state, they possess awesome stiffness and high apparent shear strength, however upon flooding, may demonstrate a remarkable reduction in volume, consequently deteriorate in strength and collapse. In this research, the collapse phenomenon of residual soil collected from three locations in Auchi, Northern Edo, Nigeria has been investigated on undisturbed specimens by utilizing single Oedometer test. The results obtained from Oedometer tests were utilized to form the database to develop the Artificial Neural Network model for the prediction of collapse potential induced by flood. The influences of flood, flooding pressure, void ratio, dry density and porosity on soil collapse have been investigated. Six input parameters (i.e. Flooding Pressure, Initial void ratio, Initial water content, Initial dry density, Liquid limit and Initial porosity) are considered to have the most noteworthy influences on the degree of collapse and have been utilized as the model’s inputs while the model output will be the equivalent collapse potential. The proposed network was developed using Microsoft Visual Studio 2010 and the MS.NET Framework 4.0 and source codes were written in C-Sharp (C#). A supervised learning was utilized to train the Back Propagation feed forward multi-layer ANN algorithm with the momentum coefficient and learning rate as its parameters. The prediction performance of the Artificial Neural Network model was assessed by utilizing the primary statistical criterion proposed by Shahin, et al., [1] such as the coefficient of correlation, R2, and the root mean square error, RMSE. The model outcomes demonstrated that it has the aptitude to predict the collapse potential from single Oedometer test in residual soil samples with a good degree of precision with coefficient of correlation, R2 = 0.856 and root mean square error, RMSE = 166.199.

This research work presents a study of the reliability of ground improvement methods in three states of the Niger Delta Area of Nigeria namely: Rivers, Bayelsa and Akwa –Ibom states. Natural soil which is peaty clay in nature was obtained from different locations in the area of study and improved with different percentages of chemicals, cement, ranging from 2% to 10% and geotextile materials after which reliability analysis was carried out on them for CBR and UCS tests. Results show that geotextile materials are not suitable for improving the peaty clay soils in the locations under study due to poor values of reliability while the reliability values obtained for soil improved with cement increases with increase in percentage addition of cement and curing period. Reliability values for soil improved with chemicals shows some variability but increase as curing period increases at percentage addition of chemicals from 2% to 6% for Calcium Oxide, Calcium Chloride, Calcium Hydroxide and Aluminium Hydroxide before a decrease in value. Sodium silicate reliability peaked at 8% while the optimal value of reliability for cement was realised at 10%.

Host genetics of COVID-19 patients is constantly evolving and may play an important role in the management of hospitalized patients and the identification of new biomarkers. In 2022, numerous studies have been published examining genetic factors that may be associated with severe outcomes of COVID-19 disease, as well as different genetic biomarkers have been suggested for early diagnosis of severe SARS-CoV-2 infection. In this literature review, we provide relevant updated analyses, examining studies published in 2022 in the literature that correlate with what was published in previous years and that focused on host genetics in patients with severe or fatal forms of COVID-19, Studies using different genotyping and sequencing techniques for the identification of genetic polymorphisms with promising results on different genes of the Renin angiotensin system, Interferon system, ABO system, Apolipoprotein E, Dipeptidyl petptidase, Leucine Zipper Transcription Factor-Like Protein 1(LZTFL1) and HLA system in diverse populations.
