San-Martin, L, Ogunbodede E, Kalenderian E.  2013.  A 50-year audit of published peer-reviewed literature on pit and fissure sealants, 1962–2011, 2013/06/14. Acta odontologica Scandinavica. 71 Abstract

Objective:Pit and fissure sealants have been used for many decades to prevent the initiation of caries on susceptible tooth surfaces. The purpose of this study was to analyze the peer-reviewed published scientific literature on pit and fissure sealants over the last 50 years.
Materials and methods:
On the PubMed database, all publications on pit and fissure sealants from 1962-2011 were extracted using the search phrase [(pit OR fissure) AND (sealant OR sealants OR adhesive)]. Details of all retrievals were individually entered into SPSS for analysis.
Results:
A total of 2829 publications were found. The mean number of authors was 2.73 ± 1.90 (range = 1-23). Although single-authorship was the modal group with 32.1%, it had a sustained decrease from 75.0% for 1962-1971 to 17.6% for 2002-2011. On the contrary, publications with three or more authors increased from 8.3% to 47.3% during the same period. Human studies accounted for 88.6% and clinical trial was 11.9%, followed by reviews at 10.2% and randomized controlled trials at 6.9%. English was the language of reporting for 82.0% of the studies.
Conclusion:
It is anticipated that future research on pit and fissure sealants will focus on newer and more effective materials.

San-Martin, L, Castaño A, Bravo M, Tavares M, Niederman R, Ogunbodede E.  2013.  Dental sealant knowledge, opinion, values and practice of Spanish dentists, 2013/02/08. BMC oral health. 13:12. Abstract

BackgroundMultiple guidelines and systematic reviews recommend sealant use to reduce caries risk. Yet, multiple reports also indicate that sealants are significantly underutilized. This study examined the knowledge, opinions, values, and practice (KOVP) of dentists concerning sealant use in the southwest region of Andalusia, Spain. This is a prelude to the generation of a regional plan for improving children’s oral health in Andalusia.
Methods
The survey’s target population was dentists working in western Andalusia, equally distributed in the provinces of Seville, Cadiz, and Huelva (N=2,047). A convenience sample of meeting participants and meeting participant email lists (N=400) were solicited from the annual course on Community and Pediatric Dentistry. This course is required for all public health sector dentists, and is open to all private sector dentists. Information on the dentist’s KOVP of sealants was collected using four-part questionnaire with 31, 5-point Likert-scaled questions.
Results
The survey population demographics included 190 men (48%) and 206 women (52%) with an average clinical experience of 10.6 (± 8.4) years and 9.3 (± 7.5) years, respectively. A significant sex difference was observed in the distribution of place of work (urban/suburb) (p=0.001), but no sex differences between working sector (public/private). The mean ± SD values for each of the four KOVP sections for pit and fissure sealants were: knowledge = 3.57 ± 0.47; opinion = 2.48 ± 0.47; value = 2.74 ± 0.52; and practice = 3.48 ± 0.50. No sex differences were found in KOVP (all p >0.4). Independent of sex: knowledge statistically differed by years of experience and place of work; opinion statistically differed by years of experience and sector; and practice statistically differed by years of experience and sector. Less experienced dentists tended to have slightly higher scores (~0.25 on a Likert 1–5 scale). Statistically significant correlations were found between knowledge and practice (r=0.44, p=0.00) and between opinion and value (r=0.35, p=0.00).
Conclusions
The results suggest that, similar to other countries, Andalusian dentists know that sealants are effective, have neutral to positive attitudes toward sealants; though, based on epidemiological studies, underuse sealants. Therefore, methods other than classical behavior change (eg: financial or legal mechanisms) will be required to change practice patterns aimed at improving children's oral health.

Sanni, M, Odekunle T, Adesina F.  2012.  Spatio-Temporal Variation of Drought Severity in the Sudano-Sahelian Region of Nigeria: Implications for Policies on Water Management, 2012/09/01. :415-430. Abstract

The African Ministerial Council on Science and Technology agreed that drought is one of the major environmental problems thatis afflicting the African continent, with its consequent negative impacts on the socioeconomic development of the affected
areas. It is within this context that this study assessed the spatio-temporal variation of drought severity in the Sudano-Sahelian
region (SSR) of Nigeria, which is highly vulnerable to drought. The study analysed spatio-temporal variation of drought severity
in the region between 1961 and 2006 using the Standardized Precipitation Index (SPI) and Principal Component Analysis (PCA).
It was established that most of the extreme droughts of the highest magnitude were recorded around the 1970s and 1990s and
that there were indications that this would continue in the future. Results also identified sub-regions characterized by a
different level of drought risks in the region. The study concluded by making appropriate policy recommendations for effective
water management for the region.

Neurology. 94(10) Abstract

ObjectiveTo characterize risk factors for spontaneous intracerebral hemorrhage (sICH) occurrence and severity among West Africans.MethodsThe Stroke Investigative Research and Educational Network (SIREN) study is a multicenter case-control study involving 15 sites in Ghana and Nigeria. Patients were adults ≥18 years old with CT-confirmed sICH with age-, sex-, and ethnicity-matched stroke-free community controls. Standard instruments were used to assess vascular, lifestyle, and psychosocial factors. Factors associated with sICH and its severity were assessed using conditional logistic regression to estimate odds ratios (ORs) and population-attributable risks (PARs) with 95% confidence intervals (CIs) for factors.ResultsOf 2,944 adjudicated stroke cases, 854 were intracerebral hemorrhage (ICH). Mean age of patients with ICH was 54.7 ± 13.9 years, with a male preponderance (63.1%), and 77.3% were nonlobar. Etiologic subtypes of sICH included hypertension (80.9%), structural vascular anomalies (4.0%), cerebral amyloid angiopathy (0.7%), systemic illnesses (0.5%), medication-related (0.4%), and undetermined (13.7%). Eight factors independently associated with sICH occurrence by decreasing order of PAR with their adjusted OR (95% CI) were hypertension, 66.63 (20.78-213.72); dyslipidemia, 2.95 (1.84-4.74); meat consumption, 1.55 (1.01-2.38); family history of CVD, 2.22 (1.41-3.50); nonconsumption of green vegetables, 3.61 (2.07-6.31); diabetes mellitus, 2.11 (1.29-3.46); stress, 1.68 (1.03-2.77); and current tobacco use, 14.27 (2.09-97.47). Factors associated with severe sICH using an NIH Stroke Scale score >15 with adjusted OR (95% CI) were nonconsumption of leafy green vegetables, 2.03 (1.43-2.88); systolic blood pressure for each mm Hg rise, 1.01 (1.00-1.01); presence of midline shift, 1.54 (1.11-2.13); lobar ICH, 1.72 (1.16-2.55); and supratentorial bleeds, 2.17 (1.06-4.46).ConclusionsPopulation-level control of the dominant factors will substantially mitigate the burden of sICH in West Africa.

Background: Acute infections have been posited as potential precipitants or triggers of the occurrence of stroke among adults with traditional vascular risk factors. We evaluated associations between stroke occurrence and reported febrile illness within 4 weeks (potential antecedent infections) among West Africans. Methods: The Stroke Investigative Research and Educational Network (SIREN) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria. Cases include adults aged ≥18 years with radiologically confirmed strokes. Controls were stroke-free adults matched with cased by age, gender and ethnicity. Detailed evaluations for vascular, lifestyle and psychosocial factors were performed. Participants were asked for evidence of any febrile illness within the past 4 weeks. We used conditional logistic regression to estimate adjusted odds ratios (aOR) with 95% Confidence Interval. Results: Among 3588 stroke cases recruited in Ghana and Nigeria between August 2014 and July 2018, 363 cases (10.1%) reported having a febrile illness within the 4 weeks prior to stroke occurrence. Having an antecedent infection was associated with stroke occurrence with an unadjusted OR of 1.19 (1.00–1.51) but aOR of 0.83 (0.59–1.17) upon adjusting for traditional vascular risk factors. Stress, aOR of 4.69 (2.59–8.50) and consumption of green vegetables 2.27 (1.35–2.85) were associated with antecedent febrile illness. Conclusion: 1 in 10 stroke cases reported antecedent history of febrile illness prior to occurrence of stroke but no independent association was observed in this study. Infectious exposures may be important triggers of cardiovascular events requiring further exploratory studies to better understand the role of this emerging risk factor.

Journal of the Neurological Sciences. 428 Abstract

Background The burden of stroke in Africa is high. Understanding how age associates with major modifiable stroke risk factors could inform tailored demographic stroke prevention strategies. Purpose To quantify the magnitude and direction of the effect sizes of key modifiable stroke risk factors according to three age groups: <50 years (young), 50–65 years (middle age) and > 65 years (elderly) in West Africa. Methods This was a case-control study involving 15 sites in Ghana and Nigeria. Cases included adults aged ≥18 years with CT/MRI scan-typed stroke. Controls were age-and gender-matched stroke-free adults. Detailed evaluations for vascular, lifestyle and psychosocial factors were performed. We estimated adjusted odds ratios (aOR) using conditional logistic regression and population attributable risk (PAR) with 95% Confidence Interval of vascular risk factors by age groups. Results Among 3553 stroke cases, 813 (22.9%) were young, 1441 (40.6%) were middle-aged and 1299 (36.6%) were elderly. Among the 5 co-shared risk factors, dyslipidemia with PAR and aOR (95%CI) of 62.20% (52.82–71.58) and 4.13 (2.64–6.46) was highest among the young age group; hypertension with PAR of 94.31% (91.82–96.80) and aOR of 28.93 (15.10–55.44) was highest among the middle-age group. Diabetes with PAR of 32.29%(27.52–37.05) and aOR of 3.49 (2.56–4.75); meat consumption with PAR of 42.34%(32.33–52.35) and aOR of 2.40 (1.76, 3.26); and non-consumption of green vegetables, PAR of 16.81%(12.02–21.60) and aOR of 2.23 (1.60–3.12) were highest among the elderly age group. However confidence intervals of risk estimates overlapped across age groups. Additionally, among the young age group cigarette smoking, psychosocial stress and cardiac disease were independently associated with stroke. Furthermore, education, stress, physical inactivity and salt intake were associated with stroke in the middle-age group while cardiac disease was associated with stroke in the elderly age group. Conclusion There is a differential influence of age on the associations of major risk factors with stroke in this West African cohort. Targeting modifiable factors predominant within an age group may be more effective as a stroke prevention strategy.
