To assess medical and nursing students' intentions to migrate abroad or practice in rural areas.
We surveyed 3199 first- and final-year medical and nursing students at 16 premier government ...institutions in Bangladesh, Ethiopia, India, Kenya, Malawi, Nepal, the United Republic of Tanzania and Zambia. The survey contained questions to identify factors that could predict students' intentions to migrate. Primary outcomes were the likelihoods of migrating to work abroad or working in rural areas in the country of training within five years post-training. We assessed predictors of migration intentions using multivariable proportional odds models.
Among respondents, 28% (870/3156) expected to migrate abroad, while only 18% (575/3158) anticipated a rural career. More nursing than medical students desired professions abroad (odds ratio, OR: 1.76; 95% confidence interval, CI: 1.25-2.48). Career desires before matriculation correlated with current intentions for international (OR: 4.49; 95% CI: 3.21-6.29) and rural (OR: 4.84; 95% CI: 3.52-6.66) careers. Time spent in rural areas before matriculation predicted the preference for a rural career (20 versus 0 years: OR: 1.53, 95% CI: 1.19-1.98) and against work abroad (20 versus 0 years: OR: 0.69, 95% CI: 0.50-0.96).
A significant proportion of students surveyed still intend to work abroad or in cities after training. These intentions could be identified even before matriculation. Admissions standards that account for years spent in rural areas could promote greater graduate retention in the country of training and in rural areas.
Purpose
To determine the histological types of brain tumors diagnosed at the Kenyatta National Hospital, Nairobi, Kenya.
Methods
This retrospective study retrieved patient-archived records at the ...Kenyatta National Hospital for the period 2016–2019. The histological types of brain tumors were assessed according to age, sex, and the WHO classification for CNS tumors using the GNU PSPP version 1.6.2-g78a33 software. Results were presented in tables and figures.
Results
During the study period, brain tumors appeared to increase gradually; however, there was a decline in 2018. During the study period, 345 brain tumor records were retrieved. Data on age were missing 33 records; hence, 312 records were included for age analyses. The mean age for the pediatrics and adults was 9 (± 5 SD) and 45 (± 14 SD) years, respectively. 88 (28.2%) and 224 (71.8%) tumors were diagnosed among pediatrics and adults, respectively. Most tumors, 60 (19.2%) were reported in patients aged ≤ 10 years, followed by 55 (17.6%), 48 (15.4%), and 47 (15.1%) in patients aged 31–40, 51–60, and 41–50, years, respectively. In both pediatrics and adults, most tumors were diagnosed in females aged ≤ 10 years and 31–40 years, respectively. Overall, two peaks were observed in patients aged 5–15 years and 40–45 years. Gliomas, 43 (48.9%) and medulloblastomas, 21 (23.9%) were the most common tumors in pediatrics, whereas meningiomas, 107 (47.8%) and gliomas, 70 (31.3%) were the most common tumors in adults. Most pediatric and adult tumors were benign with 50 (56.8%) and 157 (70.1%) cases, respectively. Low-grade gliomas and medulloblastomas were the commonest benign and malignant tumors among pediatrics, with 31 (62%) and 21 (55.3%) cases, respectively. Conversely, meningiomas and high-grade gliomas were the most common benign and malignant tumors in adults, with 106 (67.5%) and 44 (65.7%) cases, respectively.
Conclusion
This study highlights the existing burden of brain tumors in Kenya and data from KNH may be representative of the national burden of BTs. This study lays a foundation for subsequent clinical and epidemiological studies and emphasizes the need to adopt existing reporting standards to help realize a complete picture of the burden of brain tumors in Kenya.
AbstractWe sought to identify independent, nonacademic predictors of medical and nursing student intent to migrate abroad or from rural to urban areas after graduation in low- and middle-income ...countries (LMIC). This was a cross-sectional survey of 3,199 first- and final-year medical and nursing students at 16 training institutions in eight LMIC. Questionnaires assessed demographics, career intentions, and preferences regarding selected career, location, and work-related attributes. Using principal component analysis, student preferences were reduced into four discrete categories of priorities: 1) work environment resources, 2) location livability, 3) altruistic job values, and 4) individualistic job values. Students' preferences were scored in each category. Using students' characteristics and priority scores, multivariable proportional odds models were used to derive independent predictors of intentions to emigrate for work outside the country, or to work in a rural area in their native country. Students prioritizing individualistic values more often planned international careers (adjusted odds ratio aOR = 1.44, 95% confidence interval CI = 1.16-1.78), whereas those prioritizing altruistic values preferred rural careers (aOR = 1.82, 95% CI = 1.50-2.21). Trainees prioritizing high-resource environments preferentially planned careers abroad (aOR = 1.38, 95% CI = 1.12-1.69) and were unlikely to seek rural work (aOR = 0.60, 95% CI = 0.49-0.73). Independent of their priorities, students with prolonged prior rural residence were unlikely to plan emigration (aOR = 0.67, 95% CI = 0.50-0.90) and were more likely to plan a rural career (aOR = 1.53, 95% CI = 1.16-2.03). We conclude that use of nonacademic attributes in medical and nursing admissions processes would likely increase retention in high-need rural areas and reduce emigration "brain drain" in LMIC.
To describe the effect of monocular deprivation on densities of neural retinal cells in rabbits.
Thirty rabbits, comprised of 18 subject and 12 control animals, were included and monocular ...deprivation was achieved through unilateral lid suturing in all subject animals. The rabbits were observed for three weeks. At the end of each week, 6 experimental and 3 control animals were euthanized, their retinas was harvested and processed for light microscopy. Photomicrographs of the retina were taken and imported into FIJI software for analysis.
Neural retinal cell densities of deprived eyes were reduced along with increasing period of deprivation. The percentage of reductions were 60.9% (P < 0.001), 41.6% (P = 0.003), and 18.9% (P = 0.326) for ganglion, inner nuclear, and outer nuclear cells, respectively. In non-deprived eyes, cell densities in contrast were increased by 116% (P < 0.001), 52% (P < 0.001) and 59.6% (P < 0.001) in ganglion, inner nuclear, and outer nuclear cells, respectively.
In this rabbit model, monocular deprivation resulted in activity-dependent changes in cell densities of the neural retina in favour of the non-deprived eye along with reduced cell densities in the deprived eye.
Specialty distribution in Kenya continues to exhibit gender disparities despite the increasing number of female medical students graduating each year. This study aimed at assessing specialty ...preferences and factors influencing these choices among male and female medical students in Kenya.
Four hundred and fifty medical students, from first to fifth year of study at the University of Nairobi, were each issued a self-administered questionnaire designed to assess their specialty preferences and factors influencing these choices. The specialty preferences were compared with the actual distribution of specialists in Kenya. Data collected were analyzed using Statistical Package for Social Sciences.
Three hundred and eighty five (85.6%) questionnaires were completed. Surgery had the highest preference rate followed by pediatrics, internal medicine and obstetrics and gynecology. Significantly more males preferred surgery than females who mainly selected pediatrics (p<0.001). There was an increased likelihood of female students choosing controllable lifestyle specialties. These preferences mirrored the actual distribution of specialists in Kenya. Male students significantly considered prestige in a specialty (p=0.006), while their female counterparts mostly considered ease of raising a family and gender distribution in the specialty (p<0.001).
Gender-based similarities and differences exist in factors influencing specialty preferences among Kenyan medical students. These factors may explain the observed specialist doctor distribution in the country.
Abstract Background context Spinal tuberculosis (TB) accounts for more than half of all cases of skeletal TB. Although Kenya has one of the highest burdens of TB, data on spinal TB in this country ...remain scarce. Purpose To highlight the clinical presentation and management of this condition in our setup. Study design Retrospective study. Setting Kenyatta National Hospital in Kenya. Patient sample One hundred twenty-nine patients. Outcome measures Patients' condition after intervention and duration of hospital stay. Methods This study involved review of patients admitted to our hospital between 2004 and 2009 with a diagnosis of spinal TB. Results The most common presenting complaints were back pain in 100 patients (77.5%) and limb weakness in 94 patients (72.9%), whereas the most frequent physical examination finding was gibbus deformity in 85 patients (65.8%). Most (79 patients, 61.2%) had severe motor and sensory impairment graded as either American Spinal Injury Association (ASIA) A or ASIA B. Imaging revealed multiple vertebrae disease in 90 patients (79.6%). Of these, the most common was two vertebrae disease in 77 patients (68.1%). All patients were managed using anti-TB drugs and analgesics; however, 33 (25.6%) required adjunctive operative management. Mean hospital stay was 53.3 days. Marked clinical improvement was seen in 91 patients (70.0%) within 6 months of treatment. Conclusion Patients with spinal TB in our setting tended to present late and with advanced disease. Therefore, a high index of suspicion should be maintained and appropriate chemotherapy started as early as possible.
Ventriculoperitoneal shunt complications have scarcely been reported in sub-Saharan Africa. This study aimed at determining the frequency of these complications and their associated risk factors in a ...Kenyan National Teaching and Referral Hospital.
This cross-sectional study retrospectively covered 117 patients admitted to the Kenyatta National Hospital neurosurgical ward between January 2005 and December 2007 with ventriculoperitoneal shunt complications. The data obtained were analysed using the Statistical Package for the Social Sciences.
The most common complication was obstruction in 63 patients (53.8%), followed by migration in 25 (21.4%) and infection in 23 (19.7%) of the patients. Up to 49.6% of the complications occurred in patients younger than 6 months. Multiple complications were seen in 23.9% of the cases. The mean shunt duration was 18.05 months. Positive correlations existed between the presence of a shunt complication and patient age, shunt duration and the number of complications developed. These correlations were, however, neither strong nor statistically significant.
This study reports the highest frequencies of shunt obstruction and migration ever recorded in the literature. The high rate of development of multiple shunt failures coupled with a short shunt duration calls for a closer monitoring of patients with ventriculoperitoneal shunts.
Monocular deprivation results in anatomical changes in the visual cortex in favor of the non-deprived eye. Although the retina forms part of the visual pathway, there is scarcity of data on the ...effect of monocular deprivation on its structure. The objective of this study was to describe the effects of monocular deprivation on the retinal ganglion cell dendritic features. The study design was quasi-experimental. 30 rabbits (18 experimental, 12 controls) were examined. Monocular deprivation was achieved through unilateral lid suture in the experimental animals. The rabbits were observed for three weeks. Each week, 6 experimental and 3 control animals were euthanized, their retina harvested and processed for light microscopy. Photomicrographs of the retina were taken using a digital camera then entered into FIJI software for analysis. The number of primary branches, terminal branches and dendritic field area among the non-deprived eyes increased by 66.7%(p=0.385), 400%(p=0.002), and 88.4%(p=0.523) respectively. Non-deprived eyes had 114.3% more terminal dendrites (p=0.002) compared to controls. Among deprived eyes, all variables measured had a gradual rise in the first two weeks followed by decline with further deprivation. There were no statistically significant differences noted between the deprived and control eyes. Monocular deprivation results in increase in synaptic contacts in the non-deprived eye, with reciprocal changes occurring in the deprived eye.
The cerebellum has a long, protracted developmental period that spans from the embryonic to postnatal periods; as a result, it is more sensitive to intrauterine and postnatal insults like nutritional ...deficiencies. Folate is crucial for foetal and early postnatal brain development; however, its effects on cerebellar growth and development are unknown. The aim of this study was to examine the effects of maternal folate intake on the histomorphology and cell density of the developing cerebellum. Twelve adult female rats (rattus norvegicus) were randomly assigned to one of four premixed diet groups: standard (2 mg/kg), folate-deficient (0 mg/kg), folate-supplemented (8 mg/kg) or folate supra-supplemented (40 mg/kg). The rats started their diets 14 days before mating and consumed them throughout pregnancy and lactation. On postnatal days 1, 7, 21 and 35, five pups from each group were sacrificed, and their brains were processed for light microscopic analysis. Histomorphology and cell density of the external granule, molecular, Purkinje and internal granule layers were obtained. The folate-deficient diet group had smaller, dysmorphic cells and significantly lower densities of external granule, molecular, Purkinje and internal granule cells. Although the folate-enriched groups had greater cell densities than the controls, the folate-supplemented group had considerably higher cell densities than the supra-supplemented group. The folate supra-supplemented group had ectopic Purkinje cells in the internal granule cell layer. These findings imply that a folate-deficient diet impairs cellular growth and reduces cell density in the cerebellar cortex. On the other hand, folate supplementation increases cell densities, but there appears to be an optimal dose of supplementation since excessive folate levels may be detrimental.
•What is already known on the subjectGlobal morbidity and mortality from road traffic injuries (RTIs) are substantial, especially in low- and middle-income countries (LMICs) such as Kenya. RTIs have ...major economic impacts on households, communities, and nations.RTI surveillance is essential for characterizing the burden of and risk factors for RTIs, as well as for implementing and evaluating the impact of public health interventions aimed at reducing RTIs.Many countries, especially LMICs, lack a comprehensive national RTI surveillance system that consistently collects information on key variables necessary for public health action.•What this study addsWe found that RTIs in Nairobi County, an urban setting in Kenya, predominantly affected males and young adults, and we observed that nonuse of safety equipment (i.e., seat belts and helmets) among RTI cases was common.Our study demonstrates that a hospital-based RTI surveillance system is practical in LMIC settings and can provide critical information to guide public health practice and policy. This pilot study also elucidates some challenges related to collecting information on circumstances contributing to RTIs and the need for innovative ways to systematically collect this vital information.
Kenya's estimated road traffic injury (RTI) death rate is 27.8/100,000 population, which is 1.5 times the global rate. Some RTI data are collected in Kenya; however, a systematic and integrated surveillance system does not exist. Therefore, we adopted and modified the World Health Organization's injury surveillance guidelines to pilot a hospital-based RTI surveillance system in Nairobi County, Kenya.
We prospectively documented all RTI cases presenting at two public trauma hospitals in Nairobi County from October 2018–April 2019. RTI cases were defined as injuries involving ≥1 moving vehicles on public roads. Demographics, injury circumstances, and outcome information were collected using standardized case report forms. The Kampala Trauma Score (KTS) was used to assess injury severity. RTI cases were characterized with descriptive statistics.
Of the 1,840 RTI cases reported during the seven-month period, 73.2% were male. The median age was 29.8 years (range 1–89 years). Forty percent (n = 740) were taken to the hospital by bystanders. Median time for hospital arrival was 77 min. Pedestrians constituted 54.1% (n = 995) of cases. Of 400 motorcyclists, 48.0% lacked helmets. Similarly, 65.7% of bicyclists (23/35) lacked helmets. Among 386 motor vehicle occupants, 59.6% were not using seat belts (19.9% unknown). Seven percent of cases (n = 129) reported alcohol use (49.0% unknown), and 8.8% (n = 161) reported mobile phone use (59.7% unknown). Eleven percent of cases (n = 199) were severely injured (KTS <11), and 220 died.
We demonstrated feasibility of a hospital-based RTI surveillance system in Nairobi County. Integrating information from crash scenes and hospitals can guide prevention.
