African swine fever virus (ASFV) is the etiological agent of ASF, a fatal hemorrhagic fever that affects domestic pigs. There is currently no vaccine against ASFV, making it a significant threat to the pork industry. The ASFV genome sequence has been published; however, about half of ASFV open reading frames have not been characterized in terms of their structure and function despite being essential for our understanding of ASFV pathogenicity. The present study reports the three-dimensional structure and function of uncharacterized protein, pB263R (NP_042780. 1), an open reading frame found in all ASFV strains. Sequence-based profiling and hidden Markov model search methods were used to identify remote pB263R homologs. Iterative Threading ASSEmbly Refinement (I-TASSER) was used to model the three-dimensional structure of pB263R. The posterior probability of fold family assignment was calculated using TM-fold, and biological function was assigned using TM-site, RaptorXBinding, Gene Ontology, and TM-align. Our results suggests that pB263R has the features of a TATA-binding protein and is thus likely to be involved in viral gene transcription.

Omole RA, Malebo HM, Nondo RSO, Katani S, Mbugi H, Midiwo J, Moshi MJ. "In vivo Anti-plasmodial Activity of Crude Extracts of Three Medicinal Plants Used Traditionally for Malaria Treatment in Kenya." European Journal of Medicinal Plants. 2018;24(4):1-7. Abstract

The aim of the study was to determine the in vivo anti-plasmodial activity of three plants Rhamnus prinoides, Rubus keniensis and Garcinia buchananii which are used for malaria treatment by indigenous communities in Kenya. This work was done at the Department of Biological and Preclinical studies, Institute of Traditional Medicine, Muhimbili University of Health & Allied Sciences in October 2016 to August 2017. Male and female albino mice were infected with Plasmodium berghei (ANKA) in the Peter’s four day suppression test. Five groups of mice; Group 1 (solvent: 5 mL/kg body weight of 1% carboxymethyl cellulose), Group 5 (10 mg/kg body weight chloroquine), Groups 2, 3 and 4 were given 200, 400 and 800 mg/kg body weight of plant extracts. The results showed that 5% aqueous methanol extracts of R. prinoides, G. buchananii and R. keniensis exhibited higher anti-plasmodial activity than the 1:1 dichloromethane: methanol extracts in the preliminary testing. The doses showing 50% parasite suppression (EC50) were 139.2, 169.4 and 245.1 mg/kg body weight for R. prinoides, G. buchananii and R. keniensis, respectively. In vivo anti-plasmodial activity of the three plants has supported the traditional use of extracts of Rhamnus prinoides, Rubus keniensis and Garcinia buchananii for treatment of malaria. Isolation of compounds from these plants is in progress.

AJ O’o, Z Q, M O. "Infection in pregnancy; understanding impact on placental microenvironment and preterm birth: a review." JOGECA . 2018;29(1). Abstract

Background: Pregnancy increases susceptibility to and severity of infections caused by certain microbes and
parasites. The presence of these infectious agents at the maternofetal interface may lead to adverse pregnancy
outcomes including preterm birth either via direct action of the microbes or indirectly via alteration of the placental
microenvironment.
Objective: To summarize the literature regarding the role of various infectious agents in alteration of placental
microenvironment and predisposition to preterm birth.
Method: A review search using Google scholar, PubMed, Cochrane Library and Trip database was conducted at the
University of California San Francisco. A total of 880 abstracts were reviewed and a total of 95 studies were included.
Studies were included if they reported any information on infection during pregnancy, effect on placenta or fetal
membranes or risk of preterm birth.
Results: The current evidence indicates that various infectious agents affect pregnancy and alter placental
microenvironment at the maternofetal interface. Severity of these infections increases with gestation. Additionally,
these infections are associated with the risk of adverse obstetric outcomes including preterm birth.
Conclusion: Prevention, early detection and treatment of these infections including those that are asymptomatic is
important in maintaining integrity of the placenta and in reducing the burden of preterm births.

Description
Nearly 16% of the global population has no access to adequate, clean and safe water. Kenya, like numerous other Sub-Saharan African countries, is water scarce. Community water projects exists to supplement or complement government efforts to avail water to rural citizens. The purpose of this study was to investigate the role of community participation in the performance of community water projects in Ruiri Area, Meru County, Kenya. Specifically, the study sought to establish the influence of community participation in financial management, project governance, operations and maintenance and monitoring and evaluation on performance of Ruiri-Thau Water Project. The study adopted a descriptive survey research design. The target population was 413 respondents comprising 400 heads of household that were benefitting from Ruiri-Thau Water Project, 11 project committee members and two project donors (Catholic Diocese of Meru and Meru County Government). Proportionate stratified sampling was used to derive a sample of 211 respondents–196 household leaders, 11 project committee members and two donors. Data was collected using a structured questionnaire (for household heads and project committee members) and an interview schedule (for project donors). Data analysis and presentation was conducted using descriptive statistics with the help of IBM Statistical Package for Social Scientists (SPSS), Version 20. The study established that community participation in financial planning had a moderate positive influence on project performance; community participation in project governance had a moderate positive influence on …

There is high infiltration of Online Social Networking Platforms in learning institutions in Kenya
yet there is dearth of information on how these platforms affect learning outcome. This paper was a
systematic desk literature review. The purpose was to establish how leveraging on pedagogical
interactions through Facebook affect learning outcome. The reviewers focused on the development
of Facebook, its use in education and how its pedagogical interactions affect learning outcome.
Articles published in high impact journals including “grey literature” were desk reviewed. The
review showed that Facebook has been used by learners mostly for social interactions and not for
pedagogical interactions and its use can boast learning outcome. The researcher recommends that
learners, teachers and policy makers should accept Facebook as a pedagogical interaction tool.

Physics is one of the science subjects offered in Kenyan secondary schools. Several methods are employed by the teachers in teaching physics. Project method has been cited as a key method because it is leaner-centered and very effective in enabling learners to acquire scientific knowledge and skills. The choice and use of project method is determined by several factors like nature of content to be learned, availability of teaching resources, time available for teaching, learner and teacher characteristics among others. The purpose of this study was to determine the relationship between teacher’s characteristics and the level of usage of project method in the teaching of physics. Stratified random sampling was used to select 84 teachers from the former eight provinces of the Republic of Kenya. Data relating to teacher characteristics and their level usage of project method was collected using a questionnaire. SPSS computer package was used to analyze the data. Level of usage of project method was determined by analyzing the mean score from the responses given by the teachers on the frequency of using the method. Hypotheses were tested at 95% level of confidence. Relationship between teacher characteristics and level of usage of project method was analyzed using Chi square. The key findings of the study were that teachers with pedagogical skills have high level of use of project method in teaching physics than those without, whereas age and gender did not influence level of use of the method. In view of the findings, the researcher recommends that physics be taught by qualified teachers with pedagogical skills and frequent in-servicing of physics teachers to be undertaken irrespective of their age and gender.

The magnitude and trend of temperature and rainfall extremes as indicators of climate variability and change were investigated in the Arid and Semi-Arid Lands (ASALs) of Kenya using in-situ measurements and gridded climate proxy datasets, and analysed using the Gaussian-Kernel analysis and the Mann-Kendall statistics. The results show that the maximum and minimum temperatures have been increasing, with warmer temperatures being experienced mostly at night time. The average change in the mean maximum and minimum seasonal surface air temperature for the region were 0.74˚C and 0.60˚C, respectively between the 1961-1990 and 1991-2013 periods. Decreasing but statistically insignificant trends in the seasonal rainfall were noted in the area, but with mixed patterns in variability. The March-April-May rainfall season indicated the highest decrease in the seasonal rainfall amounts. The southern parts of the region had a decreasing trend in rainfall that was greater
than that of the northern areas. The results of this study are expected to support sustainable pastoralism system prevalent with the local communities in the ASALs.

Anopheles gambiae s.l. (Diptera: Culicidae) is responsible for the transmission of the devastating Plasmodium falciparum (Haemosporida: Plasmodiidae) strain of malaria in Africa. This study investigated the relationship between climate and environmental conditions and An. gambiae s.l. larvae abundance and modelled the larval distribution of this species in Baringo County, Kenya. Mosquito larvae were collected using a 350-mL dipper and a pipette once per month from December 2015 to December 2016. A random forest algorithm was used to generate vegetation cover classes. A negative binomial regression was used to model the association between remotely sensed climate (rainfall and temperature) and environmental (vegetation cover, vegetation health, topographic wetness and slope) factors and An. gambiae s.l. for December 2015. Anopheles gambiae s.l. was significantly more frequent in the riverine zone (P < 0.05, r = 0.59) compared with the lowland zone. Rainfall (b = 6.22, P < 0.001), slope (b = - 4.81, P = 0.012) and vegetation health (b = - 5.60, P = 0.038) significantly influenced the distribution of An. gambiae s.l. larvae. High An. gambiae s.l. abundance was associated with cropland and wetland environments. Effective malaria control will require zone-specific interventions such as a focused dry season vector control strategy in the riverine zone.

Scolastica M, Ndakala AJ, Derese S. 2018. Modeling and synthesis of antiplasmodial chromones, chromanones and chalcones based on natural products of Kenya. Biofarmasi J Nat Prod Biochem 16: 8-21. Despite numerous research that has been done on plants of Kenya resulting in the isolation of thousands of natural products, data on these natural products are not systematically organized in a readily accessible form. This has urged the construction of a web-based database of natural products of Kenya. The database is named Mitishamba and is hosted at http://mitishamba. uonbi. ac. ke. The Mitishamba database was queried for chromones, chromanones, and chalcones that were subjected to structure-based drug design using Fred (OpenEye) docking utility program with 1TV5 PDB structure of the PfDHODH receptor to identify complex of ligands that bind with the active site. Ligand-based drug design (Shape and electrostatics comparison) was also done on the ligands against query A77 1726 (38)(the ligand that co-crystallized with PfDHODH receptor) using ROCS and EON programs, respectively, of OpenEye suite. There was a substantial similarity among the top performing ligands in the docking studies with shape and electrostatic comparison that led to the identification of compounds of interest which were targeted for synthesis and antiplasmodial assay. In this study, a chromanone (7-hydroxy-2-(4-methoxyphenyl) chroman-4-one (48)) and two intermediate chalcones (2', 4'-dihydroxy-4-methoxychalcone (45) and 2’, 4’-dihydroxy-4-chlorochalcone (47)), were synthesized and subjected to antiplasmodial assay. Among these …

Introduction Urinary incontinence (UI) is the involuntary urine loss, with the
prevalence of 17% to 24% in women over 65 years-old. It has a multifactorial cause,
being a condition that affects many people in all ages mainly postmenopausal women,
it is also found in athlete women who have a high level of training associated mainly to
high impact activities.
Objective The aim of this study is to conduct a literature review that relates the
influence of physical activity on functional performance and on UI among women on
the stage of aging.
Method The bibliographical review was done in Medline, Scielo, Pubmed and Sports-
Disco databases using the keywords physical activity or exercise, postmenopause or
aging and urinary incontinence and stress urinary incontinence.
Conclusion Elderly women engaged in a regular exercise program have a lower
incidence of UI.

Intimate Partner Violence (IPV) constitute physical, sexual, social or psychological harm by a current or former partner or spouse. Many researchers have observed that intimate partner violence is directly associated with negative maternal and neonatal health outcomes. The purpose of this study was to assess nurse’s perception on non-disclosure of IPV by pregnant women. A mixed method was used to collect both quantitative and qualitative data. A demographic questionnaire was used to collect demographic data and a Likert scale was used to collect quantitative data. A structured interview schedule was used to gather qualitative data. 125 nurses and midwives were voluntarily recruited for this study. The results of this study showed that 52% (n=65) of the respondents had worked for more than 12 years and a majority (62.6%, n=77) were community health nurses. The nurses perceived that non-disclosure of IPV by pregnant was because of various barriers. Majority (n=86, 69.9%) agreed that the reason why they did not disclose IPV was because the abused survivor would still stay with the abuser after disclosure, and 66.7% (n=82) agreed that stigmatizing attitudes towards the IPV survivors from the society prevented disclosure. About 65.3% of the respondents agreed that survivors are not aware of their rights in regard toIPV reporting and that survivor’s view IPV abuse as normal. The results from this study point to the need of addressing barriers that emanate from the survivors of IPV themselves if IPV screening is to be achieved.

In this paper, nonparametric regression is employed which provides an estimation of unknown finite population
totals. A robust estimator of finite population totals in model based inference is constructed using the procedure of local linear
regression. In particular, robustness properties of the proposed estimator are derived and a brief comparison between the
performances of the derived estimator and some existing estimators is made in terms of bias, MSE and relative efficiency.
Results indicate that the local linear regression estimator is more efficient and performing better than the Horvitz-Thompson
and Dorfman estimators, regardless of whether the model is specified or mispecified. The local linear regression estimator also
outperforms the linear regression estimator in all the populations except when the population is linear. The confidence
intervals generated by the model based local linear regression method are much tighter than those generated by the design
based Horvitz-Thompson method. Generally the model based approach outperforms the design based approach regardless of
whether the underlying model is correctly specified or not but that effect decreases as the model variance increases.

Abstract

This study presents past and projected temporal changes in mean temperature and rainfall around the Marsabit Forest Reserve (MFR), a sub-humid montane forest in Kenya. Rainfall data for the period 1961–2014 and temperature data for the period 1972–2011 were acquired from the Marsabit meteorological station. Future projections (2006–2100) were based on data from five models that participated in the Coupled Model Intercomparison Project Phase 5 (CMIP5) under Representative Concentration Pathways (RCPs) 4.5 and 8.5. Climate simulations for the 2071–2100 period were compared to the 1961–1990 IPCC baseline period to establish significant change. The MFR recorded a mean rainfall of 784 mm which declined annually at a rate of 6 mm over the period of the study. The long rains (March–May) recorded a mean of 379 mm and decreased annually by 10 mm while the short rains (October–December) recorded a mean of 269 mm and decreased annually by 2 mm between 1961 and 2014, with no statistically significant trend (p > 0.05).

The model ensemble reproduced the MFR bimodal rainfall pattern, but overestimated the short rains at 333 mm, compared to the actual mean of 269 mm, and underestimated the long rains at 331 mm, compared to the actual mean of 379 mm. The model ensemble simulated a historical mean rainfall of 651 mm compared to the actual mean of 784 mm. Annual rainfall is projected to increase under both scenarios with higher increases during the OND season compared to the MAM season and under RCP8.5 than under RCP4.5. The mean rainfall in the baseline year was 859 mm while the mean rainfall in the projection period for the RCP4.5 and RCP8.5 scenarios is expected to be 1022 (+19%) and 1105 (+28.7%) mm, respectively; significant enough to be characterized as climate change.

Temperatures are projected to increase at a rate of 0.2 °C and 0.5 °C per decade under RCP4.5 and RCP8.5, respectively. Between 2071 and 2100, the MFR is projected to have warmed by between 1.2–1.7 °C and 3.2–4.8 °C under RCP4.5 and RCP8.5, respectively. Extreme rainfall events are projected to increase under the RCP4.5 scenario (severe wetting 13.1%, severe drying 3%) and the RCP8.5 scenario (severe wetting 20.1%, severe drying 3%) compared to the baseline period (severe wetting 6.1%). Our results conform to the ‘East African climate paradox’, where the observed rainfall trends were declining compared to the scenario simulations projecting a wetting anomaly as local temperatures rise. Further studies to better understand the cause of the poor rainfall simulation in the general circulation models (GCMs) in the MFR and the larger East African region will be necessary.

Climate change and variability is bound to impact Smallholder Dairy Farming Systems as a result of overreliance on rainfed fodder production; yet climate models project increased frequencies of droughts that have a bearing on the Length of Growing Period. Similarly higher environmental temperatures are partly attributed to biome-range shifts, implying a likelihood of emerging and re-emergence of livestock and fodder diseases and pests. Nonetheless not much is documented of perceptions and adaptation strategies employed by Smallholder Dairy Farming Systems geared towards resilience to climatie shocks. By employing a mixed method approach that included household surveys, focused group discussions and statistical data analysis using SPSS package, this study aimed to bridge some of the existing gaps in adaptation strategies on Smallholder Dairy Farming Systems in Siaya Sub-County of Western Kenya. Survey results obtained from 100 households and Focused Group Discussions revealed that the climate of the study location was perceived to have changed, with droughts singled out as the most frequent. These perceptions were consistent with long-term climate data analysis which affirmed that all seasons, i.e. MAM, JJA, and DJF with the exception of SON showed longterm drying trends. Similarly, environmental temperature showed upward trends in both maximum and minimum temperatures that were perceived to be the cause of proliferation of noxious weeds previously associated with hotter areas of the Sub-County. Typologies of adaptation strategies used in the study showed that adaptation options were limited since these were viewed through a narrow lens of disease control by regular spraying and maize stovers as supplementary livestock feed during fodder dearth periods. This study recommends that besides awareness creation of adverse impacts of climate change and variability, facilitation for ease of access to technologies that ameliorate its adverse effects ought to be put in place. Additionally, empirical studies on consequences of biome range shifts on pasture and fodder productivity, and future possible impacts of diseases on Bos taurus breeds associated with climate change and variability should be undertaken.

Rainfall modeling is significant for prediction and forecasting purposes in agriculture, weather derivatives, hydrology, and risk and disaster preparedness. Normally two models are used to model the rainfall process as a chain dependent process representing the occurrence and intensity of rainfall. Such two models help in understanding the physical features and dynamics of rainfall process. However rainfall data is zero inflated and exhibits overdispersion which is always underestimated by such models. In this study we have modeled the two processes simultaneously as a compound Poisson process. The rainfall events are modeled as a Poisson process while the intensity of each rainfall event is Gamma distributed. We minimize overdispersion by introducing the dispersion parameter in the model implemented through Tweedie distributions. Simulated rainfall data from the model shows a resemblance of the actual rainfall data in terms of seasonal variation, means, variance, and magnitude. The model also provides mechanisms for small but important properties of the rainfall process. The model developed can be used in forecasting and predicting rainfall amounts and occurrences which is important in weather derivatives, agriculture, hydrology, and prediction of drought and flood occurrences.

Due to global land surface warming, severe temperature events are expected to occur more frequently and more extremely causing changes in biodiversity and altering movement and survival of large herbivores. There are increasing observations of escalating wildlife range losses worldwide. In this study, we investigated 15 large wild herbivores (4 migratory, 1 dispersing and 10 residents) and their potential range changes in relation to projected temperatures changes based on three Representative Concentration Pathways (RCPs) 2.6, 4.5 and 8.5. Previous studies of Kenyan savannah have shown that increases in temperature can reduce the densities of wildlife significantly and after certain thresholds the species can be lost in those landscapes. The range maps of the 15 species were developed from aerial censuses that have been conducted in the arid and semi-arid lands of Kenya. We analysed temperature changes for the three RCPs for the periods 2030s, 2050s and 2070s. And based on the temperature threshold for each of the 15 species we analysed which wildlife range areas will be lost. Our results project that for the RCP 2.6, 3 out of the 15 species are projected to lose more than 50% of their range by the year 2030s, and 5 out 15 by 2050s and 4 of 15 by 2070s. The second climate scenario of RCP 4.5 projects that by 2030s, 3 species will lose more than 50% of their range, and in 2050s and 2070s 5 species. The RCP 8.5 which is the extreme scenario of temperature changes projects 5 species to lose their range by 50% in 2030s, 7 species by 2050s and 10 species by 2070s. The extent of range loss was different among species but was severe for buffalo, Thomson’s gazelle, waterbuck, and wildebeest which are also water dependent species.
However, the elephant, gerenuk, hartebeest, lesser kudu, and oryx are expected to retain most of their range in all the RCPs scenarios. These range contractions raise serious concerns about the future of wildlife in Kenyan savannah based on projected climate changes. And therefore, it is imperative the wildlife sector develops climate policies and plans that take into account the projected climate scenarios.

In Kenya, there is limited empirical data on determinants of seropositivity in late pregnancy due to low uptake of HIV retesting in late pregnancy despite there being a policy directive to do so. Study objective was to determine the predisposing factors that lead to HIV seropositivity during pregnancy among women in Kakamega and Nairobi county Hospitals. A ten month longitudinal study was conducted employing both qualitative and quantitative design whereby 1,156 HIV positive and negative women were recruited in early pregnancy and followed up through pregnancy; they were interviewed, and retested.
Results showed that having multiple sex partners was associated with seropositivity. Cultural belief of men not having sex spouses in pregnancy encouraged extra marital affairs leading to seropositivity. In conclusion HIV seropositivity in pregnancy was mainly due to the risky sexual behavior. There is therefore need for behavior change to reverse retrogressive cultural beliefs and practices.

"Prevalence and causes of vision loss in Latin America and the Caribbean in 2015: magnitude, temporal trends and projections." The British journal of ophthalmology. 2018. AbstractWebsite

OBJECTIVE: To estimate the prevalence and causes of blindness and vision impairment for distance and near in Latin America and the Caribbean (LAC) in 2015 and to forecast trends to 2020.

METHODS: A meta-analysis from a global systematic review of 283 cross-sectional, population-representative studies from published and unpublished sources from 1980 to 2014 in the Global Vision Database included 17 published and 6 unpublished studies from LAC.

RESULTS: In 2015, across LAC, age-standardised prevalence was 0.38% in all ages and 1.56% in those over age 50 for blindness; 2.06% in all ages and 7.86% in those over age 50 for moderate and severe vision impairment (MSVI); 1.89% in all ages and 6.93% in those over age 50 for mild vision impairment and 39.59% in all ages and 45.27% in those over 50 for near vision impairment (NVI). In 2015, 117.86 million persons were vision impaired; of those 2.34 million blind, 12.46 million with MSVI, 11.34 million mildly impaired and 91.72 million had NVI. Cataract is the most common cause of blindness. Undercorrected refractive-error is the most common cause of vision impairment.

CONCLUSIONS: These prevalence estimates indicate that one in five persons across LAC had some degree of vision loss in 2015. We predict that from 2015 to 2020, the absolute numbers of persons with vision loss will increase by 12% to 132.33 million, while the all-age age-standardised prevalence will decrease for blindness by 15% and for other distance vision impairment by 8%. All countries need epidemiologic research to establish accurate national estimates and trends. Universal eye health services must be included in universal health coverage reforms to address disparities, fragmentation and segmentation of healthcare.

Background: Enhanced malaria control has resulted in its reduction in some areas of Sub Saharan Africa including Rwanda. However, asymptomatic hosts serve as a reservoir for the malaria parasite for communities. The objective of this study was to determine the prevalence of malaria parasites and risk factors associated with malaria infection among children underfive years in Huye district, Rwanda.

Methods: This community-based cross sectional study was conducted from May to June 2016 among underfive years children. Asymptomatic children underfive years of age were randomly selected from 13 villages. Thick and thin blood smears were prepared from each child for malaria parasite diagnosis. Interviews with parents or guardians were conducted to collect data on malaria associated risk factors. Observations were made of the presence of mosquito breeding sites near and around the homestead.

Results: A total of 222 children were included in the study. Nearly a third (28.8%) of the children were within the age of 25-36 months. The majority (54%) of the children were females. Most of the parents/guardians were married (95.9%), nearly all (99.5%) had attended primary school and most (97.3%) were peasants. The overall Plasmodium falciparum prevalence in children was 12.2%. Children aged 1 to 12 months were 3.5 times more likely to have malaria parasites than children aged 13 to 59 months [AOR=3.56; 95%CI=1.18-10.71; p=0.024]. Children who were not sleeping under insecticide treated nets were 15 times more likely to be infected with malaria parasites compared to those who were sleeping under nets [AOR=15.27; 95%CI=4.42-52.82; p<0.001].

Conclusion: Malaria parasite prevalence in under-five year children in Huye District, Rwanda is moderate. The asymptomatic infections in the community forms a reservoir for transmission in the area. Young age of the child and not sleeping under mosquito net were associated with malaria parasite infection. The continuing use of mosquito nets needs to be emphasized.

ABSTRACT
The objectives of this study were to establish the prevalence of DVT in cancer patients at KNH medical and oncology wards, to describe patient characteristics of those with DVT vs those without and compare rates of DVT in different types of cancer. This was a cross-sectional descriptive study carried out at the Kenyatta National Hospital general medical wards and oncology wards. Patients were interviewed and examined. Patients’ records were perused for information relevant to the study. Patients with history and physical examination findings suggestive of a thrombotic event were screened by compression sonography to confirm a DVT. A total of 266 patients with a diagnosis of cancer were studied, 29 (10.9%) had DVT. Among the patients who were found to have DVT, 13 (44.8%) had gynaecological cancers, 3 (10.3%) breast cancer, 3(10.3%) prostate cancer, 3(10.3%) gastric cancer, 2(6.9%) patients had lymphoma and a patient (3.4%) each in the multiple myeloma, adenocarcinoma, squamous cell carcinoma and pancreatic cancer groups. Some significant patient characteristics in the patients who had a DVT were female sex (P value 0.014), presence of comorbidities (P 0.004) and ECOG scores of 3 and 4 (P 0.04, 0.001). Some common risk factors known for DVT were analysed and some were found to be significant in our patient group. Of the significant risk factors,
presence of comorbid condition, female sex and higher ECOG scores were noted. Keywords: DVT, VTE, ECOG, Comorbidities, Kenyatta National Hospital
