Self-reported colorectal cancer screening of Medicare beneficiaries in family medicine vs. internal medicine practices in the United States: a cross-sectional study
Angela Y Higgins, Anna R B Doubeni, Karon L Phillips, Adeyinka O Laiyemo, Becky Briesacher, Jennifer Tjia, Chyke A Doubeni
BMC Gastroenterology , 2012, DOI: 10.1186/1471-230x-12-23
Abstract: Nationally representative sample of non-institutionalized beneficiaries who received medical care from FPs or internists in 2006 (using Medicare Current Beneficiary Survey). The main outcome was the percentage of patients screened in 2007. We also examined the percentage of patients offered screening.Patients of FPs, compared to those of internists, were less likely to have received an FOBT kit or undergone home FOBT, even after accounting for patients' characteristics. Compared to internists, FPs' patients were more likely to have heard of colonoscopy, but were less likely to receive a screening colonoscopy recommendation (18% vs. 27%), or undergo a colonoscopy (43% vs. 46%, adjusted odds ratios [AOR], 95% confidence interval [CI]-- 0.65, 0.51-0.81) or any CRC screening (52% vs. 60%, AOR, CI--0.80, 0.68-0.94). Among subgroups examined, higher income beneficiaries receiving care from internists had the highest screening rate (68%), while disabled beneficiaries receiving care from FPs had the lowest screening rate (34%).Patients cared for by FPs had a lower rate of screening compared to those cared for by internists, despite equal or higher levels of awareness; a difference that remained statistically significant after accounting for socioeconomic status and access to healthcare. Both groups of patients remained below the national goal of 70 percent.Screening has been shown to decrease the risk of mortality for colorectal cancer (CRC) [1-4]. Although the use of CRC screening has increased in the US, particularly over the past decade [5,6], for many groups, screening rates are below the Healthy People goal of 70% [7]. Primary care physicians (PCPs) play an important role in the delivery of CRC screening services [6,8-12] by advising, recommending, performing and/or referring patients for screening [13]. It is therefore not surprising that studies have consistently reported a strong association between healthcare provider recommendations for and receipt of CRC screenin

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0081352
Abstract: Background Colonic polyps are common tumors occurring in ~50% of Western populations with ~10% risk of malignant progression. Dietary agents have been considered the primary environmental exposure to promote colorectal cancer (CRC) development. However, the colonic mucosa is permanently in contact with the microbiota and its metabolic products including toxins that also have the potential to trigger oncogenic transformation. Aim To analyze fecal DNA for microbiota composition and functional potential in African Americans with pre-neoplastic lesions. Materials & Methods We analyzed the bacterial composition of stool samples from 6 healthy individuals and 6 patients with colon polyps using 16S ribosomal RNA-based phylogenetic microarray; the Human intestinal Tract Chip (HITChip) and 16S rRNA gene barcoded 454 pyrosequencing. The functional potential was determined by sequence-based metagenomics using 454 pyrosequencing. Results Fecal microbiota profiling of samples from the healthy and polyp patients using both a phylogenetic microarraying (HITChip) and barcoded 454 pyrosequencing generated similar results. A distinction between both sets of samples was only obtained when the analysis was performed at the sub-genus level. Most of the species leading to the dissociation were from the Bacteroides group. The metagenomic analysis did not reveal major differences in bacterial gene prevalence/abundances between the two groups even when the analysis and comparisons were restricted to available Bacteroides genomes. Conclusion This study reveals that at the pre-neoplastic stages, there is a trend showing microbiota changes between healthy and colon polyp patients at the sub-genus level. These differences were not reflected at the genome/functions levels. Bacteria and associated functions within the Bacteroides group need to be further analyzed and dissected to pinpoint potential actors in the early colon oncogenic transformation in a large sample size.

BMC Ophthalmology , 2008, DOI: 10.1186/1471-2415-8-24
Abstract: Retrospective case analysis of 472 patients with traumatic hyphaema admitted to the University College Hospital, Ibadan between January 1997 and December 2006.The home was the single most frequent place of injury for all cases and for 75% of cases in children aged 0–10 years. Injuries that occurred at school comprised about one-fifth of cases. Sport-related injuries were uncommon.The most common activities preceeding injuries were play, corporal punishment and assault. Stones, sticks and whiplash were the agents that caused traumatic hyphaema. Occupational-related hyphaema that caused injuries was mostly in farmers and artisans, few of whom used protective goggles. The majority of patients were males. Children and young adults aged ≤ 20 years comprised 63.6% of patients. A total of 336 (76%) eyes had at least one surgical intervention. While 298 (73.2%) patients had visual acuity (VA) less than 6/60 at presentation, 143 (37.0%) of eyes had visual acuity (VA) < 6/60 3 months after injury.The injuries leading to traumatic hyphaema occur mostly at home and school, and frequently affect children and young adolescents. Over one-third resulted in blindness in the affected eye. The focus should be on prevention of stick-related eye injuries at these locations and improving access to eye health services for patients who sustained eye injuries.The eyes are the third most common organs affected by injuries, next to the hands and feet [1], despite the fact that they represent only 0.27% of the total body area and 4% of the facial area. Eye injuries still remain one of the most common causes of unilateral blindness worldwide. Blunt eye injuries mostly result in traumatic hyphaema and are not an infrequent cause of presentation to the emergency units of many eye clinics [2-8]. Most result from unnecessary eye injuries, which are largely preventable.Although eye injuries are a major public health problem globally, most studies have come from developed countries.

Abstract: The study examined the perceptions of both teachers and students in some secondary schools in Nigeria on the perceived problems and issues they encounter in teaching and learning in their large, overcrowded and under-resourced classroom. One hundred and ten teachers and 500 students from 20 secondary schools purposively selected from Ibadan metropolis, Nigeria, constituted the sample. The focus of the study was to collect a base-line data that could help to address this perennial problem in Nigeria schools. Five research questions were raised and addressed in the study and a stakeholder`s perceptions questionnaire (for both teachers and students) constituted the main instrument for data collection. Findings from the study indicate that both the selected teachers and students agreed that large classes constitute a hindrance to effective teaching and learning in their schools. Some of the problems identified with such classes are: lack of discipline and poor class control, it gives no room for effective teacher-student relationship; teachers could not identify students by their names, non-availability and ineffective teaching learning materials, among others. Implications of all these findings for policy making was discussed, prominent among which is for various governments to build more classrooms and provide more teaching and learning materials.
Brain arteriovenous malformations: Report of a case
O Adeyinka, PO Ibinaiye
Nigerian Journal of Surgical Research , 2005,
Abstract: Brain Arteriovenous Malformation (BAVM) is a form of congenital vascular malformation that are present at birth, and may be evident clinically, and usually will grow commensurately with the child. We report an adult ,a 40-year-old woman with brain arteriovenous malformation presenting with headache and epileptic seizures. CT scan demonstrated a Serpinginous enhanced brain lesion and angiography further supported the diagnosis with presence of tortuous, dilated and arterio-venous communicating cerebral vessels. These findings were later confirmed at surgery and supported with histology. Nigerian Journal of Surgical Research Vol. 7(1&2) 2005: 216–219

Abstract: Muro Banded Iron-Formation occurs in the Proterozoic Toto Schist Belt, central Nigeria. It consists preponderantly of oxide facies and minor carbonate facies. The oxide facies is made up of alternating bands of quartz (metachert) with those of hematite + magnetite + martite ± goethite, chlorite, pyrrhotite and garnet. The carbonate facies consists of quartz (metachert) + siderite ± goethite. In the oxide facies the total iron content (Fe2O3t) ranges from 33.95% to 48.08% and the SiO2 content from 50.33% to 64.50%. In the case of the carbonate facies, the Fe2O3t content varies from 15.42% to 20.66% and SiO2 content from 66.84 to 72.86%. The Al2O3 content is generally low ranging from 0.1% to 0.54% in the oxide facies, and 0.24% to 0.31% in the carbonate facies. Chemically, the Muro Iron-Formation is similar to the Lake Superior-type iron-formations in terms of the distribution of the major and trace elements. This taken together with similarities in lithological associations indicates its deposition in similar environments i.e. shallow intra-continental or restricted/barred marine basin. The very low Al2O3 contents indicate minor clastic dilution of the original chemical precipitates.

Abstract: Geospatial applications are becoming indispensible part of information systems, they provides detailed informations regarding the attribute data of spatial objects in real world. Due to the rapid technological developments in web based geographical information systems, the uses of web based geospatial application varies from Geotagging to Geolocation capabilities. Therefore, effective utilization of web based information system can only be realized by representing the world in its original view, where attributes data of spatial objects are integrated with spatial object and available for the user on the web, using integrated Google API and Google Earth API. In this study a city in the south-western part of Nigeria called EDE is examined and used as a case study. Using Google Map API and Google Earth API, the attribute data of the study area stored in XML databases will be integrated with the corresponding existing spatial data of the study area; to create a web based 3D geospatial application. We envisage that this system will enhance the effectiveness of web-based Geographical Information System (GIS) and the overall user experience.

International Journal of Poultry Science , 2006,
Abstract: The chicks used in this experiment were obtained from a population of naked neck broiler chickens that has been kept in NAPRI since 1998. Six Hundred chicks were obtained from four hatches, one week apart. At hatch, pedigreed chicks were wing-banded and housed on deep litter in an open house. Body weights were measured biweekly up to 8 weeks of age. Other measurements taken include Neck length, Back length, keel length and breast angle. The general least square means were 37.22 ± 0.32, 210.46 ± 1.97, 744.33 ± 4.31, 1351.3 ± 7.91 and 2428.1 ± 14.61g for wt at day old (WT0D), weight at 2 weeks (WT14D), weight at 4 weeks (WT28D), weight at 6 weeks (WT42D) and weight at 8 weeks (WT56D), respectively. While measurements taken included Neck length, Back length, keel length and breast which were 7.31 ± 0.06, 15.99 ± 0.05, 5.63 ± 0.04, 10.44 ± 0.04cm respectively. The heritability estimates ranged from low value of 3.013 ± 0.08 for keel length to 0.315 ± 0.22 for WT0D. There were negative genetic correlations between WT0D and other traits. This study showed that additive heritabilities are low for linear body measurement and moderate for body weight for naked neck chickens during rearing.

International Journal of Poultry Science , 2006,
Abstract: The data used to calculate the variance components of various production traits was obtained from records of about 4000 hens daughters of about 180 cocks mated to about 1,500 dams and collected over 5 year period. Two strains of Rhode Island Chickens were involved in this study. Within the red strain population sire`s contribution to total variation in age at first egg did not exceed 8.6% across the year and 6.9% in the white strain. Except for body weight at 40 weeks of the red strain where the contribution of the sire exceed 14%, the contribution of the sire to the total variation for all the economic traits considered in this study were generally low for both strain of the layer type chickens under consideration. Generally dam component of variance were higher most of the time and in many traits within the red strain population.
