With increased numbers of older people a higher burden of neurological disorders worldwide is predicted. Stroke and other cerebrovascular diseases do not necessarily present with different phenotypes in Africa but their incidence is rising in tandem with the demographic change in the population. Age remains the strongest irreversible risk factor for stroke and cognitive impairment. Modifiable factors relating to vascular disease risk, diet, lifestyle, physical activity and psychosocial status play a key role in shaping the current spate of stroke related diseases in Africa. Hypertension is the strongest modifiable risk factor for stroke but is also likely associated with co-inheritance of genetic traits among Africans. Somewhat different from high-income countries, strokes attributed to cerebral small vessel disease (SVD) are higher >30% among sub-Saharan Africans. Raised blood pressure may explain most of the incidence of SVD-related strokes but there are likely other contributing factors including dyslipidaemia and diabetes in some sectors of Africa. However, atherosclerotic and cardioembolic diseases combined also appear to be common subtypes as causes of strokes. Significant proportions of cerebrovascular diseases are ascribed to various forms of infectious disease including complications of human immunodeficiency virus. Cerebral SVD leads to several clinical manifestations including gait disturbance, autonomic dysfunction and depression. Pathological processes are characterized by arteriolosclerosis, lacunar infarcts, perivascular spaces, microinfarcts and diffuse white matter changes, which can now all be detected on neuroimaging. Except for isolated cases of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy or CADASIL, hereditary arteriopathies have so far not been reported in Africa. Prevalence estimates of vascular dementia (2–3%), delayed dementia after stroke (10–20%) and vascular cognitive impairment (30–40%) do not appear to be vastly different from those in other parts of the world. However, given the current demographic transition in both urban and rural settings these figures will likely rise. Wider application of neuroimaging modalities and implementation of stroke care in Africa will enable better estimates of SVD and other subtypes of stroke. Stroke survivors with SVD type pathology are likely to have low mortality and therefore portend increased incidence of dementia.

Abuga K, Ongarora D, Karumbi J, Olulo M, Minnaard W, Kibwage I. "Sub-Standard Pharmaceutical Services in Private Healthcare Facilities Serving Low-Income Settlements in Nairobi County, Kenya." Pharmacy. 2019;7(4):167. Abstract

Background: Quality pharmaceutical services are an integral part of primary healthcare and a key determinant of patient outcomes. The study focuses on pharmaceutical service delivery among private healthcare facilities serving informal settlements within Nairobi County, Kenya and aims at understanding the drug procurement practices, task-shifting and ethical issues associated with drug brand preference, competition and disposal of expired drugs. Methods: Forty-five private facilities comprising of hospitals, nursing homes, health centres, medical centres, clinics and pharmacies were recruited through purposive sampling. Structured electronic questionnaires were administered to 45 respondents working within the study facilities over an 8-week period.
Results: About 50% of personnel carrying out drug procurement belonged to non-pharmaceutical cadres namely; doctors, clinical officers, nurses and pharmacy assistants. Drug brand preferences among healthcare facilities and patients were mainly pegged on perceived quality and price. Unethical business competition practices were recorded, including poor professional demeanour and waiver of consultation fees veiled to undercut colleagues. Government subsidized drugs were sold at 100% profit in fifty percent of the facilities stocking them. In 44% of the facilities, the disposal of expired drugs was not in conformity to existing government regulatory guidelines. Conclusions: There is extensive task-shifting and delegation of pharmaceutical services to non-pharmaceutical cadres and poor observance of ethical guidelines in private facilities. Strict enforcement of regulations is required for optimal practices.

Direct diagnosis and characterization of cancer in tissue via trace biometals analyzed by energy dispersive X-ray fluorescence (EDXRF) spectrometry is challenging, as it requires sensitive detection and accurate quantitative analysis of the appropriate cancer biomarkers. The EDXRF spectrometry technique is not directly applicable due to the complexity of the tissue biopsy samples that are of limited size and irregular geometry, enhanced scatter from the sample dark matrix and extreme matrix effects as well as spectral overlaps and prominent Bremsstrahlung that masks the subtle biomarker analyte peaks. We report on the direct determination of biometals namely Cu, Mn, Fe, Zn; Mg, Co and Na and associated speciation (for Cu, Mn, Fe) in soft body tissue in the context of disease diagnostics utilizing a robust chemometrics enabled energy dispersive X-ray fluorescence and scattering (EDXRFS) spectrometric method. The EDXRFS method exploits, in addition to multiple fluorescence spectral signatures, scatter profiles associated with the trace metals and dark matrix to determine through hybridized multivariate chemometrics calibration models, the biometals in thin (10 μm) tissue sections. Wavelet transform (WT), principal component analysis (PCA) and independent component analysis (ICA) were used for spectral preprocessing towards model optimization using con-jointly artificial neural network (ANN) and partial least squares (PLS) based on paraffin wax ‘standards’ spiked with the cancer biomarker trace metals. Results obtained from applying oyster tissue standard validated models (to ≤6% accuracy) to dog tissues (used here as human body tissue analogues) show that both prostate and mammary malignant tissues have significantly high concentration of Zn i.e. 301 ± 4 μg/g and 301 ± 4 μg/g respectively when compared to benign tissues i.e. 160 ± 3 μg/g and 171 ± 10 μg/g. The same is the case for Fe and Cu. The concentrations of Fe, Zn, Cu and Mg in malignant (mammary) as compared to benign tissues occur in the ratios 3:1, 2:1, 3:1 and 2:1. On the other hand, for prostate malignant compared to benign tumor the corresponding ratios are 5:2, 2:1, 2:1 and 2:1 respectively. Prostate cancer was found to be characterized by strong positive correlation between Cu and Mg (0.999) and Mn and Fe (0.999) while mammary cancer is characterized by strong negative correlations between Cu and Mg (−0.994), Mn and Fe (−0.974). ICA and PCA were further used to successfully discriminate the dog tissue to 97% accuracy as either cancerous or non-cancerous based on validated pattern recognition PCA-ICA models for the determination of speciation of Cu, Fe and Mn in soft body tissue. For both mammary and prostate cancer malignancy was characterized by higher speciation of Cu, Fe and Mn (i.e. Cu2+, Fe3+, and Mn7+) compared to the benign. The results of this study demonstrate that robust chemometrics enabled EDXRFS spectrometry not only determine directly and rapidly but also accurately in a diagnostics manner cancer biomarker trace metals in soft body tissue. The technique has an additional advantage in that it has inbuilt multivariate capability to model the determined levels, their ratios and correlations as well as alterations in the speciation of the biometals to detect and characterize cancer (according to severity) as well discriminate among different types of cancer in the same tissue in a simple methodology that has potential for clinical applications.

Postpartum haemorrhage remains the leading cause of maternal mortality globally. Mortality and severe morbidity due to postpartum haemorrhage is highest in lower-resource settings. Tranexamic acid is an anti-fibrinolytic drug that has been in use in humans for nearly five decades. It is a structural analogue of lysine that binds irreversibly to plasminogen, thereby inhibiting the binding of plasmin to fibrin. This in turn inhibits fibrinolysis, thus stabilizing blood clots. Tranexamic acid has been shown to improve outcomes in trauma-related bleeding. New research has shown that early use of tranexamic acid (within 3 hours of birth), in addition to standard care, safely reduces deaths due to bleeding in women with clinically diagnosed postpartum haemorrhage, regardless of the mode of birth.

Bioassay-guided screening of Hypoestes verticillaris whole plant CH2Cl2:MeOH (1:1) extract for anti-plasmodial activity yielded four new compounds: two lignans 2, 6-dimethoxysavinin (1), 2,6-dimethoxy-(7E)-7,8-dehydroheliobuphthalmin (2); and two fusicoccane diterpenoids: 11(12)-epoxyhypoestenone (3) and 3(11)-epoxyhypoestenone (4). The chemical structures were determined using various spectroscopic techniques: UV–vis, IR, CD, 1D, 2D and MS. Two fractions (RAO-43B and RAO-43D) and the isolated compounds were tested for activity against CQ susceptible (D6) and resistant (W2) Plasmodium falciparum parasite strains, in vitro and the IC50 values determined. While the whole extract and some resultant fractions displayed moderate activity, the isolated compounds exhibited mild anti-plasmodial activity against the both strains ranging from IC50 value of 328 μM in 1 to 93 μM in 3 against W2 strain.

Abstract

An important aspect of the UN Framework Convention on Climate Change (UNFCCC), which aims to limit the increase in global temperature to 1.5 °C by 2050, has been the development of monitoring and evaluation plans that integrate climate change perspectives into new policies and programs for the protection and functioning of ecological systems. These include measures that enhance adaptive capacity, strengthen resilience and reduce vulnerability to climate change. Ecosystem change and the interaction of the different drivers of change in ecosystems have been studied at different temporal and spatial scales across different disciplines. However, the use of long temporal records documenting environmental and climatic change in understanding the impacts of the interacting drivers of change and planning sustainable use of resources is relatively new. We present examples of the use of palaeoecological data from East Africa in planning for the long-term sustainable use of natural resources by providing long-term historical perspectives on human–environment–societal–wildlife interactions and engagement with the biocultural heritage and societal evaluations of these spaces to achieve an increasingly diverse set of conservation, social and economic objectives. We link the Earth system processes whose associated boundaries can be directly related to sustainable development goals in our attempt to prevent unacceptable environmental change. The realisation that humans are having a significant impact on climate and landscapes means we now need to showcase the societal relevance of palaeoecological research and utilise its output especially in our efforts to remain within a safe operating space for humanity and ecosystems.

Awori MN, khan Mohamed MN, Mohamed AA. "Utility of the Bidirectional Glenn Shunt." Annals of African Surgery. 2019. AbstractWebsite

Background: Congenital heart disease (CHD) is a significant cause of childhood morbidity and mortality worldwide. Bi-directional Glenn Shunts (BDGS) form part of the surgical strategy used to treat CHD; no data exists on BDGS usage in the study locality. Methods: A 7-year retrospective, descriptive study was carried out at the Kenyatta National Hospital in Nairobi, Kenya, between 1 January 2006 and 31 December 2012. Results: Eleven BDGS were performed on 11 patients; 63.6% had tricuspid atresia, 27.3% had double outlet right ventricle and 9.1% had pulmonary atresia with intact ventricular septum.

Conclusion: Further studies are warranted to identify factors contributing to the late performance of BDGS, poor post-operative follow-up and failure to perform FC.

Interest rate derivatives form part of the largest portion of traded financial instruments. Hence, it is important to have models that describe their dynamics accurately. This study aims at pricing Quanto caps and floors using the multi-curve cross-currency LIBOR market model (MCCCLMM) dynamics. A Black Scholes MCCCLMM Quanto caplet and floorlet formula is first derived. The MCCCLMM parameters are then calibrated to exactly match the USD and GBP cap market prices. The estimated model parameters are then used to price the Quanto options in the Black MCCCLMM Quanto caplet and floorlet formula. These prices are then compared to the Quanto cap and floor prices estimated via Monte Carlo simulations so as to ascertain its pricing accuracy

Variant anatomy of the testicular artery is important for safe surgery in the retroperioneal area, and
accurate diagnosis of testicular and renal disease. The pattern of origin, number, course and branching
display ethnic and geographical variations. Data from black African populations and especially Eastern
Africa is scarce. The objective of this study was, therefore, to describe the topography of the intraabdominal
part of testicular artery in a sample of the Kenyan population. This was a descriptive crosssectional
study on one hundred (100) testicular arteries at the Department of Human Anatomy, University
of Nairobi. The samples were obtained from autopsy cases and cadaveric specimens. Standard midline
abdominal incisions were made, flaps of the anterior abdominal wall reflected and the intestines,
mesentery and pariental peritoneum retracted systematically to expose the testicular arteries. Their site
and level of origin, number, course and branching were examined. Macrographs of representative
variations were taken using a high resolution digital camera. The results were analysed using SPSS
version 21, and are presented using macrographs and frequency tables. Thirty three (33%) of the arteries
displayed a variant anatomy, with regard to their site of origin (8%), number (4%), course (14%) and
branching pattern (7%). Among the 14 cases of aberrant course, five (5%) arched over the left renal
vein, eight (8%) were retrocaval and one (1%) had a retroureteric course. Seven (7%) bifurcated within
the abdomen. The level of origin along the aorta varied from 1 centimetre above the renal arteries to 5.5
centimetres below them while the vertebral level of origin ranged from T12 to L4. This shows that the
testicular artery among Kenyans displays a high prevalence of variant anatomy characterized by origin
from the accessory renal artery, high level of aortic origin, duplication, retrocaval course and
intraabdominal; division. Preopertaive evaluation of renal and gonadal vasculature is recommended to
minimize misdiagnosis and inadvertent injury retroperitoneal surgery.

Background
Antenatal corticosteroids (ACS) have long been regarded as a cornerstone intervention in mitigating the adverse effects of a preterm birth. However, the safety and efficacy of ACS in hospitals in low-resource countries has not been established in an efficacy trial despite their widespread use. Findings of a large cluster-randomized trial in six low- and middle-income countries showed that efforts to scale up ACS use in low-resource settings can lead to harm. There is equipoise regarding the benefits and harms of ACS use in hospitals in low-resource countries. This randomized controlled trial aims to determine whether ACS are safe and efficacious when given to women at risk of imminent birth in the early preterm period, in hospitals in low-resource countries.

Methods/design
The trial design is a parallel, two-arm, double-blind, individually randomized, placebo-controlled trial of ACS (dexamethasone) for women at risk of imminent preterm birth. The trial will recruit 6018 women in participating hospitals across five low-resource countries (Bangladesh, India, Kenya, Nigeria and Pakistan). The primary objectives are to compare the efficacy of dexamethasone with placebo on survival of the baby and maternal infectious morbidity. The primary outcomes are: 1) neonatal death (to 28 completed days of life); 2) any baby death (any stillbirth postrandomization or neonatal death); and 3) a composite outcome to assess possible maternal bacterial infections. The trial will recruit eligible, consenting pregnant women from 26 weeks 0 days to 33 weeks 6 days gestation with confirmed live fetuses, in whom birth is planned or expected within 48 h. The intervention comprises a regimen of intramuscular dexamethasone sodium phosphate. The comparison is an identical placebo regimen (normal saline). A total of 6018 women will be recruited to detect a reduction of 15% or more in neonatal deaths in a two-sided 5% significance test with 90% power (including 10% loss to follow-up).

Discussion
Findings of this trial will guide clinicians, programme managers and policymakers on the safety and efficacy of ACS in hospitals in low-resource countries. The trial findings will inform updating of the World Health Organization’s global recommendations on ACS use.

There is a gradual paradox shift from the utilization of surface water to groundwater in both urban and rural Kenya. This is because surface water is both diminishing in quantity due to climate variability and deteriorating in quality due to high levels of anthropogenic contamination. In the quest to attain the Sustainable Development Goal number 6 that aim at ensuring access to safe water by all by 2030, the Government of Kenya is encouraging the development of groundwater resources whose potential is enormous though it has not been quantified. The Inter-governmental Authority on Development (IGAD) supported this research on the shared Mt. Elgon trans-boundary aquifer between Kenya and Uganda aimed at understanding its dynamics. Mt. Elgon is a Tertiary age mountain that straddles the Kenya-Uganda border and has a trans-boundary aquifer. This study investigated the groundwater chemistry and its implication on water management and human health. Physico-chemical parameters of water that included electrical conductivity, pH, and temperature were measured in the field and the major cations and anions were measured at the Central Laboratories of the State Department for Water. Geological mapping and identification of sanitary risks were undertaken during the field work. The study revealed that the concentration of cations and anions in the groundwater varied spatially and temporally. Abundance of these ions were in the order Ca²⁺ > Na⁺ > Mg²⁺ > K⁺ for most samples and HCO₃⁻ > Cl⁻ > SO₄²⁻ >NO₃⁻. Interpretation of hydro-chemical data suggests that calcium carbonate dissolution, halite dissolution, Ca/Na ion exchange and Mg/Na ion exchange are the major processes that control the ground-water chemistry. Chemical results indicate further that the groundwater is suitable for domestic use but is threatened by both anthropogenic and geological factors. Extensive use of fertilizer and the destruction of the catchment area coupled with low permeability and rock-water interactions in the metamorphic rock terrains are the main threats to groundwater quality in the region. A few water points had water with some ionic composition exceeding WHO and the local KEBS maximum limits for drinking water. Such water pose a risk to human health.

Safe water of adequate quantity, and dignified sanitation, is vital for the sustenance of a healthy and productive human population. In the recognition of this, the United Nations formulated the Sustainable Development Goal No. 6 to ensure access to safe water and sanitation by all by 2030. Actualization of this Goal requires information on the existing status of water resources and sanitation levels. Knowledge on contamination of groundwater is essential to prevent risks to human health. The objective of this study was to determine groundwater contamination in Kisumu, Kenya. A total of 275 water samples were collected from 22 sites within the informal settlements between December 2016 and December 2017. The samples were analysed for bacterial contamination and physical chemical quality. Thermal tolerant coliform bacteria enumeration was used as a proxy to bacteria contamination, and the pH, turbidity, dissolved oxygen, conductivity, salinity and temperature were used as physical chemical indicators of contamination. The results indicate that groundwater in Kisumu hosed coliform bacteria and therefore didn’t comply with contamination limits for domestic water proposed by WHO and local KEBS standards. The results further indicated that the levels of bacteriological contamination vary with water type, shallow well having the highest bacterial loads. The study concluded that there were potential risks to human health due to high content of coliform bacteria. The study attributed the contribution to pit latrines that were present in virtually all compounds. The pit latrines are located close to the water points. The study recommended the definition of minimum distance between the pit latrines and shallow wells to minimize contamination. The low income dwellers should be educated on simple ways of treating drinking water contaminated by microbial to minimize enteric infections.

Safe water of adequate quantity, and dignified sanitation, is vital for the sustenance of a healthy and productive human population. In the recognition of this, the United Nations formulated the Sustainable Development Goal No. 6 to ensure access to safe water and sanitation by all by 2030. Actualization of this Goal requires information on the existing status of water resources and sanitation levels. Knowledge on contamination of groundwater is essential to prevent risks to human health. The objective of this study was to determine groundwater contamination in Kisumu, Kenya. A total of 275 water samples were collected from 22 sites within the informal settlements between December 2016 and December 2017. The samples were analysed for bacterial contamination and physical chemical quality. Thermal tolerant coliform bacteria enumeration was used as a proxy to bacteria contamination, and the pH, turbidity, dissolved oxygen, conductivity, salinity and temperature were used as physical chemical indicators of contamination. The results indicate that groundwater in Kisumu hosed coliform bacteria and therefore didn’t comply with contamination limits for domestic water proposed by WHO and local KEBS standards. The results further indicated that the levels of bacteriological contamination vary with water type, shallow well having the highest bacterial loads. The study concluded that there were potential risks to human health due to high content of coliform bacteria. The study attributed the contribution to pit latrines that were present in virtually all compounds. The pit latrines are located close to the water points. The study recommended the definition of minimum distance between the pit latrines and shallow wells to minimize contamination.

The sub-surface is used in most parts of Africa as a repository of human waste and as a source of groundwater through pit latrines and shallow wells respectively. The wells provide freshwater to millions of people in Africa who are either not connected to the piped water or have intermittent supplies. These shallow wells are hand dug and therefore are mostly less than 20 meters in depth. This same sub-surface environment is also used as a repository of human waste through pit latrines. The water points and the sanitation facilities are mostly located close to each other. This study aimed at appraising the groundwater and sanitation challenges based on a rapid survey, sampling, interviews, existing literature review and historical borehole data in Kisumu city, Kenya. Previous studies in the area have shown that the number of shallow wells, city buildings, density of unimproved pit latrines and sanitary risks have increased tremendously between 1999 and 2019. Most of the wells are shallow and therefore prone to contamination by pollutants. Fluoride and chloride content in most boreholes are above the recommended WHO maximum values and the local KEBS standards. The study confirmed that the main water and sanitation challenges in Kisumu are poor and deteriorating water quality, poor waste disposal management systems and poor sanitation services. There is need for the introduction of new and sustainable groundwater approaches supported by scientific models and involving all stakeholders. Current deficiencies in the provision of adequate water and dignified sanitation to the poor in Kisumu can be remedied through improved knowledge on shallow aquifer dynamics and innovative research. It was noted that apart from the donor agencies and multi-national NGOs, the private investors are unwilling to invest in water projects in Kisumu due in part to government legislation that constrains the cost that may be levied on water

Based on a five-town case-study cohort in Kenya, a conceptual framework has been developed to enable the formulation of holistic and effective strategies that encompass the national aspirations and regional to global sustainability agendas, and which can be used to monitor progress in achieving set objectives. The approach is flexible, scalable and transferrable, so that it can be applied in different contexts and using different indicators, based upon the same construct. Insufficient technical knowledge of urban aquifers and their interplay with the wider social-ecological system constrains the development of holistic, effective and robust management systems to ensure their sustainability for intended uses. The objective was to consider governance and management solutions that could promote water security for urban towns in Kenya through the sustainable use of groundwater in the context of its complex hydrogeology, water access disparities, competing uses and future risks. The in force national and county water policies, strategies, and plans for the case study areas were critically reviewed. The status of aquifer knowledge, water access disparities, competing uses, and risks was evaluated from critical literature reviews and data compilation, fieldwork, and analysis of indicator datasets from the Kenya 2009 census. Key aquifers need urgent characterisation to reverse the current situation whereby development proceeds with insufficient aquifer knowledge. Private sector and public participation in management should be enhanced through decentralised management approaches.

Abstractnambati_et_al_2018.pdfnambati_et_al_2018.pdfWebsite

The use of saliva in diagnosis of infectious diseases is an attractive alternative to procedures that involve blood drawing. It promises to reduce risks associated with accidental needle pricks and improve patient compliance particularly in malaria survey and drug efficacy studies. Quantification of parasitaemia is useful in establishing severity of disease and in assessing individual patient response to treatment. In current practice, microscopy is the recommended technique, despite its limitations. This study measured the levels of Plasmodium falciparum lactate dehydrogenase (PfLDH) in saliva of malaria patients and investigated the relationship with blood parasitaemia.

"Developing open online learning resources: Lessons from a short course on the control of blindness from diabetic retinopathy.". In: College of Ophthalmologists in Eastern Central & Southern Africa (COECSA). Addis Ababa; 2018. Abstract

Background: A need identified during another study prompted the development of the open online course on control of blindness from diabetic retinopathy. In our technological age, potential for learning online can provide a unique opportunity to develop context-specific content for local relevance. We report on the lessons learnt in the development of this short online course for an international audience of diverse eye care practitioners.

Methods: We developed this online short course through a formal planning process facilitated by UNESCO. The participants included eye health educators, learning designers, and content experts. The course curriculum was informed by learning from an ongoing doctorate program, as well as by clinical, public health and educational experience.

Results: Lessons learnt include:
1. Identifying the need and content – Learning and research from a doctorate research program can inform content development.
2. Identifying the relevance – the content needs to be customized for the target audience and local context.
3. Developing the learning design – promoting digital teaching skills and co-creation of content are valuable entry points.
4. Accommodating appropriate peer review and mentorship may enhance learning and quality assurance.
5. Resource planning activities need to be documented as a learning point.
6. There are significant costs in course development, such as time spent in content development, and ongoing maintenance eg maintaining the online platform.
7. Sources of quality open access resources in eye care are limited.

Conclusion: Content development is a unique learning experience, and it is essential to develop and support context specific learning resources. Open educational practice supports a collaborative process that enhances relevance and quality of training. The online format emphasizes the importance of learning design requirements to bridge the transactional distance between the participant and the educator.

Exogenous lipoid pneumonia (ELP), an important cause of interstitial lung disease, often goes unrecognized. We conducted a retrospective study of children with histologically confirmed ELP at Red Cross Children's Hospital, South Africa. Twelve children of Zimbabwean heritage aged 2.1-10.8 months were identified between 2012 and 2017. Repeated oral administration of plant-based oil for cultural reasons was reported by 10 of 11 caregivers. Cough (12/12), tachypnoea (11/12), hypoxia (9/12), and diffuse alveolar infiltrates on chest radiography (12/12) were common at presentation. Chest computed tomography revealed ground-glass opacification with lower zone predominance (9/9) and interlobular septal thickening (8/9). Bronchoalveolar lavage specimens appeared cloudy/milky, with abundant lipid-laden macrophages and extracellular lipid on Oil-Red-O staining (12/12), with polymicrobial (6/12) and Mycobacterium abscessus (2/12) co-infection. Antibiotics, systemic corticosteroids, and therapeutic lavage were interventions in all eight and five patients, respectively. Clinicians should consider ELP in children with non-resolving pneumonia in settings with similar practices.

"Prevalence and causes of blindness and vision impairment: magnitude, temporal trends and projections in South and Central Asia." Br J Ophthalmol. 2018. AbstractWebsite

BACKGROUND:To assess prevalence and causes of vision loss in Central and South Asia.

METHODS: A systematic review of medical literature assessed the prevalence of blindness (presenting visual acuity<3/60 in the better eye), moderate and severe vision impairment (MSVI; presenting visual acuity <6/18 but ≥3/60) and mild vision impairment (MVI; presenting visual acuity <6/12 and ≥6/18) in Central and South Asia for 1990, 2010, 2015 and 2020.

RESULTS: In Central and South Asia combined, age-standardised prevalences of blindness, MSVI and MVI in 2015 were for men and women aged 50+years, 3.72% (80% uncertainty interval (UI): 1.39-6.75) and 4.00% (80% UI: 1.41-7.39), 16.33% (80% UI: 8.55-25.47) and 17.65% (80% UI: 9.00-27.62), 11.70% (80% UI: 4.70-20.32) and 12.25% (80% UI:4.86-21.30), respectively, with a significant decrease in the study period for both gender. In South Asia in 2015, 11.76 million individuals (32.65% of the global blindness figure) were blind and 61.19 million individuals (28.3% of the global total) had MSVI. From 1990 to 2015, cataract (accounting for 36.58% of all cases with blindness in 2015) was the most common cause of blindness, followed by undercorrected refractive error (36.43%), glaucoma (5.81%), age-related macular degeneration (2.44%), corneal diseases (2.43%), diabetic retinopathy (0.16%) and trachoma (0.04%). For MSVI in South Asia 2015, most common causes were undercorrected refractive error (accounting for 66.39% of all cases with MSVI), followed by cataract (23.62%), age-related macular degeneration (1.31%) and glaucoma (1.09%).

CONCLUSIONS: One-third of the global blind resided in South Asia in 2015, although the age-standardised prevalence of blindness and MSVI decreased significantly between 1990 and 2015.

"Adapting clinical practice guidelines for diabetic retinopathy in Kenya: process and outputs." Implement Sci. 2018;13(1):81. Abstract

The use of clinical practice guidelines envisages augmenting quality and best practice in clinical outcomes. Generic guidelines that are not adapted for local use often fail to produce these outcomes. Adaptation is a systematic and rigorous process that should maintain the quality and validity of the guideline, while making it more usable by the targeted users. Diverse skills are required for the task of adaptation. Although adapting a guideline is not a guarantee that it will be implemented, adaptation may improve acceptance and adherence to its recommendations.

"Effectiveness of peer support to increase uptake of retinal examination for diabetic retinopathy: study protocol for the DURE pragmatic cluster randomized clinical trial in Kirinyaga, Kenya." BMC Public Health. 2018;18(1):871. Abstract

All patients with diabetes are at risk of developing diabetic retinopathy (DR), a progressive and potentially blinding condition. Early treatment of DR prevents visual impairment and blindness. The natural history of DR is that it is asymptomatic until the advanced stages, thus annual retinal examination is recommended for early detection. Previous studies show that the uptake of regular retinal examination among people living with diabetes (PLWD) is low. In the Uptake of Retinal Examination in Diabetes (DURE) study, we will investigate the effectiveness of a complex intervention delivered within diabetes support groups to increase uptake of retinal examination.

We compared change in HIV reservoir DNA following continued antiretroviral therapy (ART) vs short treatment interruption (TI) in early ART-treated Kenyan infants. While HIV DNA in the reservoir decayed with continued ART, HIV DNA levels were similar to pre-TI HIV DNA reservoir levels in most children after short TI.

"Circumcision status at HIV infection is not associated with plasma viral load in men: analysis of specimens from a randomized controlled trial." BMC Infect. Dis.. 2018;18(1):350. Abstract

Male circumcision provides men with approximately 60% protection from acquiring HIV infection via heterosexual sex, and has become a key component of HIV prevention efforts in sub-Saharan Africa. Possible mechanisms for this protection include removal of the inflammatory anaerobic sub-preputial environment and the high concentration of Langerhans cells on the inside of the foreskin, both believed to promote local vulnerability to HIV infection. In people who do acquire HIV, viral load is partially determined by infecting partner viral load, potentially mediated by size of infecting inoculum. By removing a portal for virion entry, prior male circumcision could decrease infecting inoculum and thus viral load in men who become HIV-infected, conferring the known associated benefits of slower progression to disease and decreased infectiousness.

Intussusceptive angiogenesis (IA) is a complementary method to sprouting angiogenesis (SA). The hallmark of IA is formation of trans-capillary tissue pillars, their fusion and remodeling of the vascular plexus. In this study, we investigate the formation of the zebrafish caudal vein plexus (CVP) in Tg(fli1a:eGFP) and the synergistic interaction of IA and SA in crafting the archetypical angio-architecture of the CVP. Dynamic in vivo observations and quantitative analyses revealed that the primitive CVP during development was initiated through SA. Further vascular growth and remodeling occurred by IA. Intussusception contributed to the expansion of the CVP by formation of new pillars. Those pillars arose in front of the already existing ones; and in a subsequent step the serried pillars elongated and fused together. This resulted in segregation of larger vascular segments and remodelling of the disorganized vascular meshwork into hierarchical tree-like arrangement. Blood flow was the main driving force for IA, particularly shear stress geometry at the site of pillar formation and fusion. Computational simulations based on hemodynamics showed drop in shear stress levels at locations of new pillar formation, pillar elongation and fusion. Correlative 3D serial block face scanning electron microscopy confirmed the morphological substrate of the phenomena of the pillar formation observed in vivo. The data obtained demonstrates that after the sprouting phase and formation of the primitive capillary meshwork, the hemodynamic conditions enhance intussusceptive segregation of hierarchical vascular tree i.e. intussusceptive arborization resulting in complex vascular structures with specific angio-architecture.

Kenya abolished delivery fees in all public health facilities through a presidential directive effective on June 1, 2013 with an aim of promoting health facility delivery service utilization and reducing pregnancy-related mortality in the country. This paper aims to provide a brief overview of this policy's effect on health facility delivery service utilization and maternal mortality ratio and neonatal mortality rate in Kenyan public health facilities.

Do DV, Gichuhi S, Vedula SS, Hawkins BS. "Surgery for postvitrectomy cataract." Cochrane Database Syst Rev. 2018;1:CD006366. AbstractWebsite

BACKGROUND:
Cataract formation or acceleration can occur after intraocular surgery, especially following vitrectomy, a surgical technique for removing the vitreous that is used in the treatment of many disorders that affect the posterior segment of the eye. The underlying problem that led to vitrectomy may limit the benefit from removal of the cataractous lens.

OBJECTIVES:
To evaluate the effectiveness and safety of surgery versus no surgery for postvitrectomy cataract with respect to visual acuity, quality of life, and other outcomes.

SEARCH METHODS:
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 5), MEDLINE Ovid (1946 to 17 May 2017), Embase.com (1947 to 17 May 2017), PubMed (1946 to 17 May 2017), Latin American and Caribbean Health Sciences Literature database (LILACS) (January 1982 to 17 May 2017), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com); last searched May 2013, ClinicalTrials.gov (www.clinicaltrials.gov); searched 17 May 2017, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 17 May 2017. We did not use any date or language restrictions in the electronic searches for trials.

SELECTION CRITERIA:
We planned to include randomized controlled trials (RCTs) and quasi-RCTs that had compared surgery versus no surgery to remove the lens from eyes of adults in which cataracts had developed following vitrectomy.

DATA COLLECTION AND ANALYSIS:
Two review authors independently screened the search results according to the standard methodological procedures expected by Cochrane.

MAIN RESULTS:
We found no RCTs or quasi-RCTs that had compared surgery versus no surgery to remove the lens from eyes of adults in which cataracts had developed following vitrectomy.

AUTHORS' CONCLUSIONS:
There is no evidence from RCTs or quasi-RCTs on which to base clinical recommendations for surgery for postvitrectomy cataract. There is a clear need for RCTs to address this evidence gap. Such trials should stratify participants by their age, the retinal disorder leading to vitrectomy, and the status of the underlying disease process in the contralateral eye. Outcomes assessed in such trials may include changes (both gains and losses) of visual acuity, quality of life, and adverse events such as posterior capsular rupture and retinal detachment. Both short-term (six-month) and long-term (one- or two-year) outcomes should be examined.

The prevalence of non-communicable diseases (NCDs) is rising in low- and middle-income countries, including Kenya, disproportionately to the rest of the world. Our objective was to quantify patient payments to obtain NCD screening, diagnosis, and treatment services in the public and private sector in Kenya and evaluate patients' ability to pay for the services.

the ankle joint is a frequently injured joint. It is also affected by inflammatory, infectious and tumoral lesions. Ultrasound is a safe and cost-effective imaging tool when evaluating the ankle joint, as most structures are superficial and accessible. The aim of the study was to determine the pattern of ultrasonographic findings of disorders of the ankle joint complex in patients presenting with ankle pain.

Patients' satisfaction is an individual's positive assessment regarding a distinct dimension of healthcare and the perception about the quality of services offered in that health facility. Patients who are not satisfied with healthcare services in a certain health facility will bypass the facility and are unlikely to seek treatment in that facility.

Nguru W, Moturi CA. "Supplier Selection Process Based on Fuzzy Logic.". In: Conference on Science and Development. College of Biological and Physical Sciences, Chiromo; 2018. Abstract

In Kenyan governmental organizations, supplier selection during procurement process is regulated by the Public Procurement and Asset Disposal act. The act requires the selection to be done on technical and financial basis, taking into consideration price, quality, time and service. The common way of selecting suppliers is by forming an evaluation committee which takes considerable time and may be characterized by biases and associated costs. Furthermore, the “quality” and “service” factors advised by the act are imprecise and subjective during an evaluation process and also challenging to quantify. This study presents an approach to help decision-makers evaluate potential suppliers by utilizing fuzzy inference system. Initially, the main quantitative and qualitative criteria used in supplier selection process in the construction service industry were identified from literatures and experts through structured questionnaires. After ranking the identified criteria, a Matlab Fuzzy Inference System (FIS) was utilized to develop the selection model. The proposed model was tested using a real tender for construction works in a government office block. We realized that the proposed model makes the selection process more systematic and achieved a shorter turn-around time as compared to an evaluation committee. It was concluded that using the Fuzzy inference system resulted in an optimum solution and thus can support in decision making when selecting suppliers thus contributes to the advancement of e-procurement in supply chain management.

Cell surface expression of α4β7, α4β1 and αEβ7 integrins play a key role in T cell distribution. Understanding the contribution of integrins to the density and ratios of CD4+: CD4negT cell at the portals of entry for HIV is of fundamental importance for the advance of more effective HIV prevention strategies. We therefore set out to characterize and compare the expression of α4β7, α4β1 and αEβ7 integrins on systemic, cervical and rectal CD4+ and CD4negT cells isolated from a cohort of healthy Kenyan women at low risk for sexually transmitted infections (STI) (n = 45). Here we show that blood and cervix were enriched in α4+β1+CD4+T cells and α4+β7hiCD4+T cells, whereas the rectum had an equal frequency of α4+β7hiCD4+T cells and αE+β7hiCD4+T cells. Most cervical and rectal αE+β7hiCD4+T cells expressed CCR5 as well as CD69. Interestingly, αEβ7 was the predominant integrin expressed by CD4negT cells in both mucosal sites, outnumbering αE+β7hiCD4+T cells approximately 2-fold in the cervix and 7-fold in the rectum. The majority of αE+β7hiCD4negT cells expressed CD69 at the mucosa. Taken together, our results show unique tissue-specific patterns of integrin expression. These results can help in guiding vaccine design and also the use of therapeutically targeting integrin adhesion as a means to preventing HIV.
