Authors: Olayinka-Olagunju Josephine Omowumi 
Published: August 2022

The exposure of the aquatic ecosystem to heavy metal from both natural and anthropogenic activities are on the rise and have harmful health effects on all aquatic organisms and human. This study assessed the concentrations of heavy metals (Fe, Pb, Cd, Cr, As and Zn) in surface water, sediments and fish tissues of Ose River and examined the histopathological changes of the tissues of two fish species (Mormyrus rume and Clarias garienpinus). Surface water, sediments and fish samples were collected and procured from Ose River in Ondo State, Nigeria from February to April 2021. Heavy metal digestions were done in the laboratory using HNO3/HCl while the concentrations were determined using Atomic Absorption Spectrometer. Histopathological alterations in the fish tissues were also assessed. Bioaccumulation factor (BAF), ecological risk index and potential ecological risk level were used to assess the investigated metal concentrations. In the surface water, the concentration of Cd (0.010–0.030 mg/l) and As (0.010–0.05 mg/l) exceeded the WHO limits of 0.01mg/l respectively while Fe, Pb, Cr and Zn were within the limits. In the sediments, all metals exceeded the limits except Pb and As. The concentrations of Pb (0.30±0.000–4.12±0.030 mg/l), Zn (9.970±0.010–30.77±0.023 mg/l), Cd (0.026±0.002–0.331±0.004 mg/l) and Cr (ND-0.331±0.004 mg/l) in the fish tissues were seen to be higher than the permissible limits of 0.5 mg/l, 5 mg/l, 0.005 mgl and 0.05-0.15 mg/l respectively. The BAF showed no probability. The alterations observed in the kidneys of the fish were cholestasis, necrosis, loss of glomeruli structure and tubular necrosis. While the gills showed congestion of the central veins and interlamellae hyperplasia caused by the presence of a monogenean parasite. The livers however revealed loss of hepatocytes nuclei, necrosis in hepatocytes and lymphocytic infiltrate. The study showed that the study site was polluted with heavy metals and may pose serious health issues to fishers, those using the water and people feeding on fish from the river. This study therefore suggests good indicators for bio-monitoring of heavy metals in Ose River. Seeing that the site was polluted with heavy metals hence, a more comprehensive assessment of the river is recommended.

Published: August 2022

Exchange rate volatility has received much attention in economic research especially with the advent of floating exchange regimes. The volatile nature of exchange rate is generally perceived as having negative affect on international trade. However, the theoretical and empirical perspective are mixed on the nature of the relationship. This study aimed at examining analyzing the moderating effect of foreign exchange reserves on the relationship between foreign exchange rate volatility and international trade in Kenya. The study used error correction model in the analysis of the time series data for the study period which spanned between 1966-2018. Results show that controlling for inflation rate, interest rate and gross domestic product, foreign exchange reserves had a positive and statistically significant moderating effect at 5% significant level on the relationship between foreign exchange rate volatility and international trade with R2 of 0.9557. The study recommends maintaining enough stock of foreign exchange reserves to cushion the economy from adverse effects of exchange rate volatility. The findings of the study will provide relevant information in the formulation of and implementation of an effective monetary policy that will promote exchange rate stability and improve the country’s performance in international trade.
Visual Data Collection in an Insecurity Environment: Blangoua, Cameroonian Window on Lake Chad
Authors: Layio Robi 
Published: August 2022

Once an anthropologist sets out a fieldwork, he/she faces myriad of challenges. While it is obvious that access to the target community is related to the prevailing socio-political context, there are even more constraints when data collection is carried out using an audiovisual tool. The aim in the present article is to share the field collaboration experience with informants in the locality of Blangoua. It shows how the audiovisual tool was an actual catalysis in this process, both for knowledge creation and for the discovery of certain latent realities among the youth of Blangoua. This paper endeavors also to highlight the visual anthropologist researcher’s ambivalent position in his/her specific involvement out in research field. Thus, starting from the principle of shared anthropology (Rouch, 1968) which would like the researcher in visual anthropology to consult his informants and show them everything that is constructed as a message from their culture, we manage to detect “truths” that emerge consciously or unconsciously from the behavior of individuals.
Christology in Contemporary African Christianity: Ontological or Functional?
Authors: Ogunlana Babatunde , Akano Benjamin I. 
Published: August 2022

This article examines the practical nature of Christology in contemporary African Christianity. The writers argue that though the religious mindset of the African people does not allow a dichotomy between ontological and functional Christologies, existential challenges have made many Africans tilt towards the functional end. The method adopted in the article is a descriptive approach. Christology is central to the orthodox Christian faith. It permeates all the pages of the Bible. The Old Testament consistently predicts the coming of the Messiah. The New Testament writers focused on Him in the light of His work on earth and the office he came to occupy concerning the Messianic predictions of the Old Testament. In history, the focus of theology has always been on the person and work of Christ. Contemporary African Christianity is not an exception to this trend. Many controversies have emerged in the process of the discussion on Christology. These Christological controversies surround the Person, picture, and deeds of Christ. A tilt towards functional Christology may cause a down-playing of God’s sovereign will to focus on what works. This may lead to syncretic beliefs and practices as people look for what gives a solution. The conclusion is that African Christology should blend ontology and functionality. The Christology that is both contextually relevant and scripturally balanced should be presented to the African people. Therefore, African theologians should make efforts to prepare theology that reflect a balanced Christological presentation intentionally.
Cotinine as an indicator of fetal exposure to active and passive smoking in pregnant women
Authors: Dulęba Marta , Kozakiewicz Barbara 
Published: August 2022

Abstract

Introduction
Within 5 years, the number of pregnant smokers in Poland decreased by 5%. Still, 6% of pregnant women are active and 18% are passive smokers, and 5% smoke and drink alcohol. The study examined the levels of cotinine concentration in the blood of pregnant women and in the umbilical cord blood of their children in relation to the number of cigarettes smoked; the places and persons conducive to exposure of pregnant women to tobacco smoke were determined.

Materials and Methods
The study included 123 women who have entered medical facilities for childbirth during physiological pregnancy, who filled out a questionnaire about their lifestyle. Moreover, venous and umbilical blood was collected from them and their newborns for cotinine evaluation. The nicotine marker was determined by the UPLC/MS/MS analytical method.

Results
When examining the frequency of smoking and exposure to smoke, it was found that 38% of the respondents concealed their smoking status by giving false answers, as shown by the biochemical analysis of the presence of cotinine in the blood. A significant correlation was found between the cotinine levels of exposed and smoking mothers and their babies. Pregnant smokers were in the presence of smokers more often (p = 0.019). Moreover, it was found that the presence of women in the company of smokers who smoked more than 20 cigarettes/day resulted in a significant (p = 0.011) increase of cotinine in the umbilical blood in 31.5% of newborns, higher than the concentration in mothers.

Conclusions
Protecting women from passive smoking requires extensive educational measures. The inclusion of cotinine level assessment in pregnant women in the program of the standard of perinatal examinations should be considered in order to protect children from diseases resulting from the effects of nicotine in the embryonic period.
The Optimal Application of Lagrangian Mathematical Equations in Computer Data Analysis
Authors: Jia Guo , Al dmour Ayman 
Published: August 2022

Abstract
Because the current computer sensor data positioning analysis has positioning difficulties and false positioning problems, we use the Lagrangian multiplier method of the interactive direction to disassemble the computer sensor sound source. Through this algorithm, the information fusion of computer sensor nodes is realized. After using Lagrangian mathematical equations, these error correction measurements have achieved better target positioning results. Theoretical analysis and experimental results show that the algorithm improves the speed of computer sensor data association. To a certain extent, the correlation accuracy is improved.
The use of metaraminol as a vasopressor in critically unwell patients: a narrative review and a survey of UK practice

Published: August 2022

Abstract

Background
Major international guidelines state that norepinephrine should be used as the first-line vasopressor to achieve adequate blood pressure in patients with hypotension or shock. However, recent observational studies report that in the United Kingdom and Australia, metaraminol is often used as second line medication for cardiovascular support.

Aim of the study
The aim of this study was to carry out a systematic review of metaraminol use for management of shock in critically unwell patients and carry out a survey evaluating whether UK critical care units use metaraminol and under which circumstances.

Methods
A systematic review literature search was conducted. A short telephone survey consisting of 6 questions regarding metaraminol use was conducted across 30 UK critical care units which included a mix of tertiary and district general intensive care units.

Results
Twenty-six of thirty contacted centres responded to our survey. Metaraminol was used in 88% of them in various settings and circumstances (emergency department, theatres, medical emergencies on medical wards), with 67% reporting use of metaraminol infusions in the critical care setting. The systematic literature review revealed several case reports and only two studies conducted in the last 20 years investigating the effect of metaraminol as a stand-alone vasopressor. Both studies focused on different aspects of metaraminol use and the data was incomparable, hence we decided not to perform a meta-analysis.

Conclusions
Metaraminol is widely used as a vasopressor inside and outside of the critical care setting in the UK despite limited evidence supporting its safety and efficacy for treating shock. Further service evaluation, observational studies and prospective randomised controlled trials are warranted to validate the role and safety profile of metaraminol in the treatment of the critically unwell patient.

Abstract
Sheehan’s syndrome is a life-threatening endocrine emergency seen in postpartum females secondary to ischemic pituitary necrosis. It is a frequent cause of hypopituitarism in developing countries that occurs secondary to postpartum haemorrhage (PPH). Patients with Sheehan’s syndrome often present with organ dysfunctions in critical care settings, secondary to stressors precipitating the underlying hormonal deficiencies. The initial clinical picture of Sheehan’s syndrome may mimic some other disease, leading to misdiagnosis and diagnostic delay. Strict vigilance, timely diagnosis, and appropriate management are essential to avoid diagnostic delay and to improve the patient outcome. In this case series, we describe 5 cases of previously undiagnosed Sheehan’s syndrome (including young, middle aged and postmenopausal females) that presented to critical care and emergency settings with organ failures.
