Ultrastructural changes in animal fat associated lipoid pneumonia: Report of two cases

The main research focus of the Electron Microscopy and Histopathology Department in the past 20 years has been in the areas of enteric diarrhoeas with special emphasis on rotavirus. Through its diarrhoea surveillance studies, the Department has helped to firmly establish rotaviruses as a major cause of diarrhoea in children, and document the circulation of unusual rotavirus genotypes in Ghana. The Department has also recently expanded its diagnostic repertoire to include the identification and characterization of noroviruses, astroviruses, and other enteric viruses.

Ultrastructural revelation of the nature of pennation in the abdominal muscles of children with spastic type cerebral palsy (stcp): Implications for force generation

Purpose: To investigate whether the pennation angle (PA) in the abdominal muscles of individuals with spastic type cerebral palsy (STCP) has undergone any change when compared with those of typically developing (TD) individuals. To determine whether PA of abdominal muscles in individuals with STCP impacts differently on the force generating capacity, from those of TD peers. Materials & methods: Ultrasound images of the four abdominal muscles namely; rectus abdominis (RA), internal oblique (IO), external oblique (EO) and transversus abdominis (TrA), were obtained during the resting and active stages. ImageJ software package (version 2012) was used to measure the PA of the sonographic images. Sixty-three individuals with STCP and eighty-two typically developing (TD) individuals took part in the study. The participants were between the ages of 7 and 16 years. Results: The PA for three out of the four abdominal muscles was less than 3∘ while the RA muscle in both groups showed a pennation angle of zero degrees during the resting and active stages. Conclusion: Excluding the rectus abdominis muscle, PA appeared to be altered in individuals with STCP when compared to their TD counterparts. The characterization of PA in abdominal muscles in both groups is, however, unclear. The PA as a muscle parameter may not be an important variable for differentiating the force generating capacity between individuals with STCP and their TD peers. Further investigation is required on MAP and the overall implication of each component on abdominal muscle function, especially in the maintenance of balance and posture.

Umar krachi's poetry between imitation and originality: a close study of two poetic works

Readers of West African Arabic poetry usually discover several features that are similar to Pre-Islamic and Islamic era poetry. This is due primarily to the fact that they unconsciously or otherwise imitate the Pre-Islamic mode of poetic composition by copying themes, tropes, and topoi, just as Abdul-Samad (2009) notes, an avid reader may spot a “deliberate, well-planned open intertextuality in both lexical and artistic terms.” Notwithstanding, West African Arabic poetry cannot be completely robbed of its unique features. This paper discusses the concepts of imitation and originality with a focus on two poems by ʿUmar Krachi. The main purpose is to explore the various ways in which the author imitates the classical mode of poetic composition, and at the same time maintains a considerable level of originality as far as West African Arabic poetry is concerned. The first poem, was written in praise of Malam Sallaw in 1928 who was Kumasi Zongo Chief, while the second poem lampoons an intruder who objected Umar’s manner of pronunciation of ‘al-hamdu lillah’. It will be shown that although Umar used the bipartite structure of the nasīb/ghazal (amatory prelude) and the theme of madīḥ (panegyric) in the panegyric poem, and monothematic structure in the lampoon poem, both poems have their unique local flavour, despite his imitation of classical Arabic poetry in style and theme.

The UN Mission in Post-War Liberia Security Sector Reform and Transition: Challenges and Prospects

The research analyzes the Security Sector Reform in post-war Liberia under the auspices of the United Nations Mission in Liberia (UNMIL) and the United States Government, from 2003 until the transition of security responsibilities to the government of Liberia in 2016. The objectives of the research basically examines the capability of the security sector as it relates to the continuation and provision of national security post-UNMIL and most significantly, after a reformed security sector. Furthermore, it delves into the challenges and prospects of the security sector, including other peacebuilding initiatives intended towards sustainable peace and security. The methodology of the research traced the origin of the civil crisis in Liberia and the collection of data relating to UNMIL’s intervention and its peacekeeping operational mandates, which included the reformation and restructuring of all major security apparatuses of Liberia with significant aid from the United States Government. The research findings suggested that after a complete reformation and restructuring of Liberia’s security sector, there are unarguable operational and administrative challenges still affecting major security apparatuses of the nation. Therefore, the effective functioning and provision of national security contains delicate challenges which are yet to be address irrespective of the tremendous progress been made in the reformation of the sector by UNMIL and the United States Government. The findings also realized that the government’s post-UNMIL security transition plan in providing sustainable peace and security seem hopeful but the present fragility of peace and security in post-war Liberia may remain if the multifold challenges of the sector which includes, inadequate logistical support, low budgetary allotments, insufficient capacity building, unethical behaviors, corruptions, weak supervisions, etc., are not discreetly tackle.

Unawareness of health insurance expiration status among women of reproductive age in Northern Ghana: implications for achieving universal health coverage

Background: Ghana implemented a national health insurance scheme in 2005 to promote the provision of accessible, affordable, and equitable healthcare by eliminating service user fees. Termed the National Health Insurance Scheme (NHIS), its active enrollment has remained low despite a decade of program implementation. This study assesses factors explaining this problem by examining the correlates of insurance status unawareness among women of reproductive age. Methods: In 2015, a random probability cross-sectional survey of 5914 reproductive-aged women was compiled in the Upper East Region, an impoverished and remote region in Northern Ghana. During the survey, two questions related to the NHIS were asked: “Have you ever registered with the NHIS?” and “Do you currently have a valid NHIS card?” If the answer to the second question was yes, the respondents were requested to show their insurance card, thereby enabling interviewers to determine if the NHIS requirement of annual renewal had been met. Results are based on the tabulation of the prevalence of unawareness status, tests of bivariate associations, and multivariate estimation of regression adjusted effects. Results: Of the 5914 respondents, 3614 (61.1%) who reported that they were actively enrolled in the NHIS could produce their insurance cards upon request. Of these respondents, 1243 (34.4%) had expired cards. Factors that significantly predicted unawareness of card expiration were occupation, district of residence, and socio-economic status. Relative to other occupational categories, farmers were the most likely to be unaware of their card invalidity. Respondents residing in three of the study districts were less aware of their insurance card validity than the other four study districts. Unawareness was observed to increase monotonically with relative poverty. Conclusion: Unawareness of insurance care validity status contributes to low active enrollment in Ghana’s NHIS. Educational messages aimed at improving health insurance coverage should include the promotion of annual renewal and also should focus on the information needs of farmers and low socio-economic groups.

Uncommon Mixed Outbreak of Pneumococcal and Meningococcal Meningitis in Jirapa District, Upper West Region, Ghana, 2016

Objective: The Jirapa District in Ghana falls within the African meningitis belt where over 500 million people are at risk of epidemic meningitis. The district suffered an outbreak of Neisseria meningitides, W (NMW) in 2012 and a mixed outbreak of Streptococcus pneumonia and NMW in early 2016. We investigated the outbreak to identify the source, causative agents, and magnitude and assess health facility preparedness and propose control measures. Design and setting: We conducted a descriptive study in all sub-districts of Jirapa, between 28thFebruary to 10th April 2016. We reviewed records at health facilities, assessed health facility preparedness, searched for cases, traced contacts of case to administer chemoprophylaxis and collect CSF for laboratory analysis. Data were entered in Microsoft excel cleaned, and exported to stata-13 for analysis by person place and time. Results: A total 233 meningitis cases were reported with mean age of 22.4years and standard deviation 21.6. Males were (57%), females (43%) and 60.8% were less than 19 years. Attack rate of meningitis was 214/100,000 with case fatality rate (CFR) of 12.4% (29/233). Causative agents were NMW (69.5%) and streptococcus pneumonia (27.1%), mainly serotype STN1 and H. influenza (3.4%). The index case had travel history to dollar power, close to Tain District which is the epicentre for the 2016 meningitis outbreak in Ghana. Conclusion: The Jirapa district experienced a mixed outbreak of streptococcal and meningococcal meningitis in early 2016, facilitated by migration. Active surveillance and mass vaccination with multivalent vaccines is required to protect the population. Funding: Ghana Field Epidemiology and Laboratory Training Programme (GFELTP).

Unconditional cash transfers and safe transitions to adulthood in Malawi

As national social safety nets are expanding in Africa and globally, evidence on the impact of programs on youth transitions can help guide future investment and program design decisions. This paper examines the effects of Malawi’s flagship cash transfer program on safe transitions to adulthood among youth living in households experiencing ultra-poverty. The evaluation was a cluster-randomized control trial implemented over three years using panel data on youth aged 13 to 19 at baseline. Household receipt of bi-monthly transfers led to im provements in four out of six outcome domains: 1) education, 2) physical health, 3) emotional wellbeing and mental health, and 4) sexual and reproductive health. There were limited or no impacts on outcomes related to HIV risk and time use. Results imply that similar programs in the region may also facilitate safe youth transitions. Nonetheless, more intentional gender- and youth-specific designs may have promise for more holistic impacts, and further evidence is needed on longer-term effects.

An unconditional quantile regression based decomposition of spatial welfare inequalities in Ghana

Ghana has witnessed tremendous economic growth since the 1990s and attained the Millennium Development Goals target of halving poverty. This notwithstanding, inequality in Ghana increased over the same period, suggesting growth benefits were not equitably distributed. This study provides evidence on the determinants of household consumption expenditure and factors that explain rural-urban welfare gaps between 1998 and 2013. The study employs an unconditional quantile regression and recently proposed decomposition technique based on re-centred influence functions. We find significant spatial differences in consumption expenditure across selected quantiles, with rural-urban inequalities driven largely by differences in returns to households’ endowments.

Uncontrolled hunting and habitat degradation decimate and extirpate forest hornbills in Ghana, West Africa

Tropical forests are on the front lines of the current global extinction crisis. Species with restricted habitat requirements and slow reproductive rates, such as the spectacular hornbills (Bucerotidae) of the Paleotropics, are particularly vulnerable. We present the first long-term quantitative population assessment of nine forest hornbill species in Ghana, part of the Upper Guinea forest biodiversity hotspot in West Africa. From 1990 to 2009, hornbill encounter rates declined with 32–88% across eight species found in the region. Seven separate surveys between 1990 and 2014 indicated declines in at least six of eight species detected, with large-bodied species hardest hit. Depleted remnant populations of large hornbills mainly persist in two large and relatively well-protected wildlife reserves, Ankasa Resource Reserve and Kakum National Park. Contrastingly, the five largest species of the nine hornbills known to Bia Biosphere Reserve, one of Ghana's few forest wildlife reserves, apparently vanished completely since the 1990s, mainly due to uncontrolled hunting. Similarly, several large hornbills have disappeared from forest reserves where hunting is widespread. We conclude that uncontrolled hunting is the major driver of the recent drastic declines and population extirpations of large hornbills, while reductions in small insectivorous species may be related to extensive fragmentation and habitat disturbances of the Ghanaian forest biome. We call for urgent conservation action to prevent further declines and impending extirpations of forest hornbills and other wildlife in West Africa. © 2018 Elsevier Ltd

Uncovering the fruit bat bushmeat commodity chain and the true extent of fruit bat hunting in Ghana, West Africa

Harvesting, consumption and trade of bushmeat are important causes of both biodiversity loss and potential zoonotic disease emergence. In order to identify possible ways to mitigate these threats, it is essential to improve our understanding of the mechanisms by which bushmeat gets from the site of capture to the consumer’s table. In this paper we highlight the previously unrecognized scale of hunting of the African straw-colored fruit bat, Eidolon helvum, a species which is important in both ecological and public health contexts, and describe the commodity chain in southern Ghana for its trade. Based on interviews with 551 Ghanaians, including bat hunters, vendors and consumers, we estimate that a minimum of 128,000 E. helvum bats are sold each year through a commodity chain stretching up to 400 km and involving multiple vendors. Unlike the general bushmeat trade in Ghana, where animals are sold in both specialized bushmeat markets and in restaurants, E. helvum is sold primarily in marketplaces; many bats are also kept by hunters for personal consumption. The offtake estimated in this paper raises serious conservation concerns, while the commodity chain identified in this study may offer possible points for management intervention. The separation of the E. helvum commodity chain from that of other bushmeat highlights the need for species-specific research in this area, particularly for bats, whose status as bushmeat is largely unknown.

Uncovering the genetic architecture and evolutionary roots of androgenetic alopecia in African me

Androgenetic alopecia is a highly heritable trait. However, much of our understanding about the genetics of male-pattern baldness comes from individuals of European descent. Here, we examined a dataset comprising 2,136 men from Ghana, Nigeria, Senegal, and South Africa that were genotyped using the Men of African Descent and Carcinoma of the Prostate Array. We first tested how genetic predictions of baldness generalize from Europe to Africa and found that polygenic scores from European genome-wide association studies (GWASs) yielded area under the curve statistics that ranged from 0.513 to 0.546, indicating that genetic predictions of baldness generalized poorly from European to African populations. Subsequently, we conducted an African GWAS of androgenetic alopecia, focusing on self-reported baldness patterns at age 45. After correcting for age at recruitment, population structure, and study site, we identified 266 moderately significant associations, 51 of which were independent (p < 10 5 , r2 < 0.2). Most baldness associations were autosomal, and the X chromosome does not seem to have a large impact on baldness in African men. Although Neanderthal alleles have previously been associated with skin and hair phenotypes, within the limits of statistical power, we did not find evidence that con tinental differences in the genetic architecture of baldness are due to Neanderthal introgression. While most loci that are associated with androgenetic alopecia do not have large integrative haplotype scores or fixation index statistics, multiple baldness-associated SNPs near the EDA2R and AR genes have large allele frequency differences between continents. Collectively, our findings illustrate how population genetic differences contribute to the limited portability of polygenic predictions across ancestries

Uncovering the untold story: exploring gender disparities in sexual harassment experiences and coping strategies among Ghanaian higher education students

Purpose – This study aims to examine students’ experiences of sexual harassment (SH) in higher education institutions (HEIs) in Ghana as well as their coping strategies. Design/methodology/approach – The study adopted the cross-sectional descriptive survey research design and used the convenience sampling technique to sample 926 students from four public Universities in Ghana. The data collected were analyzed using an independent-sample t-test with the aid of IBM SPSS Statistics version 23.0. Findings – The study found no significant difference in male and female students’ experience of gender harassment and unwanted SH. Additionally, female students were sexually coerced considerably more than males. In the case of coping strategies, the study found no significant differences among male and female students use of passive coping strategies. Finally, the study found significant differences among male and female students use of active, self-blame and benign coping strategies. Practical implications – This implies that specific attention is required when students experience SH since they may be exposed to more aggressive sexual behavior. Originality/value – The originality of this present study rest on its unique contribution by exploring the prevalent SH and coping strategies among tertiary students in HEIs in Ghana.
