RESUMEN

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a causative agent of COVID-19 is a leading cause of ill-health and deaths worldwide. Currently, COVID-19 has no known widely approved therapeutics. Thus, the need for effective treatment. OBJECTIVES: We investigated the safety and efficacy of two (2) therapeutic agents; chloroquine phosphate (CQ), 2- hydroxychloroquine (HCQ) and a control (standard supportive therapy) among hospitalized adults with COVID-19. METHODS: The clinical trial was done in accordance to the World Health Organization master protocol for investigational therapeutics for COVID-19. Atotal of 40 participants with laboratory-confirmed positive COVID-19 were enrolled. Blood samples and oropharyngeal (OP) swabs were obtained on days 1,3,15 and 29 for safety and efficacy assessments. RESULTS: The baseline demographics showed that the median ages in years (range) were 45 (31-57) in CQ, 45 (36.5-60.5) in HCQ, 43 (39.5-67.0) and 44.5 (25.3-51.3) in the control (P<0.042).At randomization, seven (7) participants were asymptomatic, thirty-three (33) had mild symptoms, eight (8) had moderate symptoms while three (3) had severe symptoms. The average day of conversion to negative COVID-19 was 15.5 days for CQ, 16 days for HCQ and 18 days for the control(P=0.036). CONCLUSION: The safety assessment revealed no adverse effect of the drugs in COVID-19 patients after treatment. These findings proved that chloroquine and hydroxychloroquine are effective for the treatment of COVID-19 among hospitalized adults. It also confirmed that they are safe.

RESUMEN

Background: The burden of hunger, food insecurity and malnutrition in sub-Saharan Africa is enormous. A higher proportion of the population suffer the consequences of food insecurity, hunger and undernourishment than previously assumed. Food insecurity among adolescents has been documented to be associated with malnutrition, poor health outcomes, low educational attainment and other negative consequences. Aim: This study therefore assessed food insecurity and its associated factors among adolescents in Sagamu, Ogun State, Nigeria. Methods: A cross-sectional study was conducted among 1300 in-school adolescents in Sagamu Township, Ogun State in southwestern Nigeria, selected via multi-stage sampling. A semi-structured, self-administered questionnaire was used for data collection. Data were analyzed with the aid of SPSS 20.0. Relevant descriptive and inferential statistics were calculated, with p < 0.05. Result: The prevalence of food insecurity was 45%, of which 34.6% had mild food insecurity, 34.7% had moderate food insecurity, while others experienced the severe form of food insecurity. Gender, age; maternal occupation, maternal education, living arrangement, low sense of self-worth, alcohol intake and cigarette smoking were associated (p < 0.05) with food insecurity. Predictors of food insecurity were: age; maternal education, living arrangement and some behavioral factors. Conclusion: The prevalence of food insecurity among adolescents in Sagamu was high. Multi-sectorial action is essential in tackling the challenges of food insecurity and its numerous consequences among adolescents, at all levels of governance.

RESUMEN

OBJECTIVE: Early childhood caries (ECC) is caries in children below the age of 72 months. The aim of the study was to determine the association of maternal psychosocial factors (general anxiety, dental anxiety, sense of coherence, parenting stress, fatalism, social support, depressive symptoms, and executive dysfunction), decision-making abilities, education, income and caries status with the prevalence and severity of ECC among children resident in Ile-Ife, Nigeria. METHODS: A dataset of 1549 mother-child (6-71-months-old) dyads collected through examinations and a household survey, using validated psychometric tools to measure the psychosocial factors, were analyzed. The DMFT for the mothers and the dmft for the child were determined. The association between maternal psychosocial factors, education, income, and decision-making ability, the prevalence of maternal caries, and the prevalence of ECC was determined using logistic regression analysis. RESULTS: The prevalence of maternal caries was 3.3%, and the mean (standard deviation-SD) DMFT was 0.10 (0.76). The ECC prevalence was 4.3%, and the mean (SD) dmft was 0.13 (0.92). There was no significant difference between the prevalence and severity of maternal caries and ECC by maternal age, education, income, or decision-making abilities. There was also no significant difference in maternal caries, ECC prevalence and ECC severity by maternal psychosocial factors. The only significant association was between the prevalence of caries in the mother and children: children whose mothers had caries were over six times more likely to have ECC than were children with mothers who had no caries (AOR: 6.67; 95% CI 3.23-13.79; p < 0.001). CONCLUSION: The significant association between ECC and maternal caries prevalence suggests that prenatal oral health care for mothers may reduce the risk for ECC.

RESUMEN

BACKGROUND: Malnutrition is associated with oral health problems. AIM: To determine the association between malnutrition (undernourished and over-nourished) and early childhood caries (ECC) in a suburban population in Nigeria. DESIGN: Data were extracted from a database of a household survey of 1549 under 6-year-old children. Explanatory variables were nutritional status (normal, undernourished [wasted, stunted and underweight], or over-nourished). The outcome measure was the prevalence of ECC. Children's sociodemographic characteristics (socio-economic status, sex, age) and caries-risk variables (frequency of sugar consumption in-between-meals, oral hygiene status) were the confounders. Association between ECC and malnutrition was determined using the Poisson regression analysis. Statistical significance was set at P ≤ .05. RESULTS: About one-third (31.4%) of children had expected height/weight for age; 848 (54.7%) were undernourished; and 215 (13.9%) were over-nourished. Nutritional status was not significantly associated with the prevalence of ECC. Children who consumed sugar in-between-meals three or more times a day were twice as likely to have ECC as were those who consumed sugar less often in-between-meals (APR: 2.23; 95% CI: 1.30-3.81; P = .003). Children 3-5 years old were more likely to have ECC than were those 0-2 years old (APR: 2.40; 95% CI: 1.10-5.22; P = .03). CONCLUSIONS: ECC was not associated with undernourished and over-nourished in a suburban population in Nigeria.

RESUMEN

BACKGROUND: To determine the validity of maternal reports of the presence of early childhood caries (ECC), and to identify maternal variables that increase the accuracy of the reports. METHODS: This secondary data analysis included 1155 mother-child dyads, recruited through a multi-stage sampling household approach in Ile-Ife Nigeria. Survey data included maternal characteristics (age, monthly income, decision-making ability) and maternal perception about whether or not her child (age 6 months to 5 years old) had ECC. Presence of ECC was clinically determined using the dmft index. Maternally reported and clinically determined ECC presence were compared using a chi-squared test. McNemar's test was used to assess the similarity of maternal and clinical reports of ECC. Sensitivity, specificity, positive and negative predictive values, absolute bias, relative bias and inflation factor were calculated. Statistical significance was determined at p < 0.05. RESULTS: The clinically-determined ECC prevalence was 4.6% (95% Confidence interval [CI]: 3.5-5.0) while the maternal-reported ECC prevalence was 3.4% (CI 2.4-4.6). Maternal reports underestimated the prevalence of ECC by 26.1% in comparison to the clinical evaluation. The results indicate low sensitivity (9.43%; CI 3.13-20.70) but high specificity (96.9%; CI 95.7-97.9). The positive predictive value was 12.8% (CI 4.3-27.4) while the negative predictive value was 95.7% (CI 94.3-96.8). The inflation factor for maternally reported ECC was 1.4. Sensitivity (50.0%; CI 6.8-93.2) and positive predictive value were highest (33.3%; CI 4.3-77.7) when the child had a history of visiting the dental clinic. CONCLUSIONS: Mothers under-reported the presence of ECC in their children in this study population. The low sensitivity and positive predictive values of maternal report of ECC indicates that maternal reporting of presence of ECC may not be used as a valid tool to measure ECC in public health surveys. The high specificity and negative predictive values indicate that their report is a good measure of the absence of ECC in the study population. Child's history of dental service utilization may be a proxy measure of presence of ECC.

RESUMEN

BACKGROUND: There is usually a strong worry with feelings over the lost individual or body parts. Amputation sometimes leads to feelings of social discomfort or public self-consciousness. Social discomfort has been linked with further psychosocial problems such as increased activity restriction, heightened worry and low mood. Studies have associated limb loss care with psychological burden, financial burden, bodily and emotional stress on family and social relationship. The purpose of this research was to determine the psychosocial effects of amputation. METHOD: A descriptive cross-sectional study involving 68 adult amputees using a structured interviewer-administered questionnaire adapted from Hospital Anxiety and Depression Scale which assessed psychological effects (anxiety and depression) and social impact scale which measured social effect of amputation on amputees. Fisher's exact test was used in the analysis to establish association using SPSS software version 23. RESULT: Disease was the major cause of amputation 54.4% and below knee amputation was the most common site (44.1%). Majority of the participants, (86.7%) had caregivers out of which family and relatives constituted 91.5% and those with co-morbid medical conditions were 48.5% with diabetes mellitus being most prevalent in 60.6% of amputees with co-morbid medical conditions.Participants who were >50 years were twelve times less likely to have anxiety compared to those who were ≤ 50 years. There was statistically significant association between age of participants and anxiety. (OR = 0.081, p = 0.013, CI = 0.011- 0.594). CONCLUSION: Majority of the participants had caregivers, out of which, family and relatives constituted significant proportion. About half of the participants had co-morbid medical conditions. Age was significantly associated with anxiety. This study revealed that having a care giver reduced depression, anxiety and social effect among amputees.

RESUMEN

BACKGROUND: Breast cancer is a global health concern and a leading cause of death among women in the world. Enhancing breast cancer screening in developing countries is pivotal in improving women's health. Aim of this study was to assess the knowledge of breast cancer and practices of breast cancer screening. METHODS: Study design was a descriptive cross sectional study among 348 public senior secondary school female teachers in Surulere LGA. Data was collected using a pretested, structured, open-ended and close-ended self-administered questionnaire. Questions on knowledge of breast cancer and practice of breast cancer screening were scored and graded as good (>50%) and poor (< 50%). The Univariate and bivariate analyses were carried out. Pvalue <0.05 was considered statistically significant. RESULTS: A total of 332 out of the 348 administered questionnaires were retrieved and analyzed giving a response rate of 95.40%. Respondents' ages ranged from 24-58 years with a mean of 42.61±5.53 years. Overall knowledge of breast cancer was good among 308(92.77%) of the respondents. Majority 264(79.52%) of the respondents performed breast self-examination (BSE), 240(72.29%) have had clinical breast examination (CBE) performed for them by a health personnel and 216(65.06%) of the respondents reported they have had a mammogram. CONCLUSION: Majority of the respondents had good knowledge of breast cancer. Most common practice of breast cancer screening was BSE, followed by CBE and lastly mammogram. Health education/awareness campaigns are therefore recommended to improve and sustain the existing knowledge and breast cancer screening practices.

RESUMEN

BACKGROUND: Dental pain is considered an important public health problem because it affects the daily life of children. This study was designed to assess the prevalence, associated factors, and impact of dental pain among 8-12-year-old school children in Lagos, Nigeria. SUBJECTS AND METHODS: A cross-sectional survey to determine self-reported dental pain among 8-12-year-old school children using an interviewer-administered questionnaire was conducted. This was followed by a clinical examination to determine the child's oral hygiene status and dental caries status. Chi-square and Fisher's exact tests were used for comparing proportions. Binary logistic regression analysis was also conducted. Statistical significance was set at P < 0.05. RESULTS: Of the 414 children included in the survey, 254 (61.4%) children and 103 (24.9%) children reported experiencing dental pain 3 months and 4 weeks before the survey, respectively. Caries prevalence was 21.0%, whereas mean decayed, missing, and filled tooth index score was 0.4420 (±1.078). A report of pain up to 3 months before the survey was significantly associated with the child's age [odds ratio (OR) = 1.254; confidence interval (CI) = 1.037-1.516; P = 0.019], whereas the type of school attended (OR = 1.786; CI = 1.124-2.840; P = 0.014) and the presence of dental caries (OR = 1.738; CI = 1.023-2.953; P = 0.041) were significantly associated with reporting pain 4 weeks before the survey. CONCLUSION: The prevalence of self-reported dental pain was high among the children surveyed. Report of dental pain was associated with the presence of dental caries. The provision of school oral health services could be useful in reducing the level of untreated caries and possibly dental pain among school children.

RESUMEN

OBJECTIVE: To report the periodontal status of older adults in Plateau State, Nigeria, and determine its Association with alcohol consumption. BACKGROUND: Periodontal disease is common among Nigerians, and the prevalence increases with age. The role that alcohol consumption plays in the occurrence of the disease among Africans is uncertain. MATERIALS AND METHODS: Sample selection was performed using a multistage cluster sampling technique among older adults in Plateau State, Nigeria. Interviews, using structured questionnaires, were conducted for each of the participants. Clinical examinations were then carried out to determine the occurrence of periodontal disease, assessed by clinical attachment loss and probing depth. RESULTS: The prevalence of periodontal disease was 79%, being severe in 46% of the population. Almost half of the participants (46.7%) examined were still actively consuming alcohol, among which 48% reported a history of intoxication. There was no statistically significant relationship between periodontal disease and the frequency of alcohol consumption, or quantity consumed on each occasion. However, alcohol consumption was highly correlated with periodontal disease among those who reported intoxication from the drink (r = 0.095; p = 0.033). A history of intoxication with alcohol was the only significant predictor of periodontal disease, after adjusting for age and gender. CONCLUSION: Periodontal disease was highly prevalent among older Nigerians in this study. Apart from those who reported intoxication from alcohol, there was no statistically significant relationship between the prevalence of periodontal disease and the frequency of alcohol consumption or the quantity consumed on each occasion.

RESUMEN

Congenital talipes equinovarus (CTEV), more commonly known as clubfoot, is a deformity of the foot that is not well understood. The tarsal navicular is at the center of the disease process and exhibits abnormal development and delayed ossification. However, its role in the pathologic process is not clear. The aim of the present study was to better understand the role of the tarsal navicular in CTEV by correlating the presence of the navicular ossification center and relapse of clubfoot deformity after surgical treatment. The medical records and radiographs of 34 patients (41 feet) with surgically treated CTEV were reviewed for the presence of the navicular ossification center and the lateral talocalcaneal angles. Of the 41 feet, 17 (41.46%) did not have the tarsal navicular ossification center present before surgery, and 24 (58.54%) did have the ossification center present. The talocalcaneal angles were similar between those with and without the navicular ossification center present. No significant difference was found in the incidence of relapse between the nonossified navicular group (17.6%) and the ossified navicular group (16.7%; p = .63). The presence of the navicular ossification center before surgery does not appear to have prognostic value for the relapse of CTEV after surgical intervention.

RESUMEN

BACKGROUND: This study aims to identify the determinants of caries prevention-oriented practice for children among final-year dental students in Nigeria. METHOD: A questionnaire was distributed to 179 final-year dental students in six dental schools in Nigeria. It requested information on age, gender, knowledge of caries prevention measures, self-perceived competency in providing caries-preventive care for children, and caries prevention-oriented practice for two hypothetical cases with high and low risk of caries. Chi-squares tests and logistic regression analysis were done. RESULTS: Between 24% and 41% of the respondents indicated their inability to determine the appropriate treatment modality for children with high and low caries risk. Majority of the students failed to differentiate between the caries-preventive practice for children with high and low risk of caries: preventive strategies for children with high caries risk were also used for those with low caries risk. Age, gender, knowledge of caries prevention measures, and self-perceived competency in providing caries-preventive care were not associated with student's capacity to provide caries-preventive practice for children. CONCLUSION: Caries-preventive practice among dental students in Nigeria could be improved. It may be important to explore the possible role of problem-based learning approach in addressing this challenge.

RESUMEN

BACKGROUND: This article reviews the caries profile for children in Nigeria and proposes an appropriate framework for addressing the silent caries epidemic. DISCUSSION: We reviewed the caries prevalence among children in Nigeria, assessed the existing responses to the caries epidemic including the national oral healthcare delivery situation in the country and discussed the current caries management in children. We then proposed a response framework for Nigeria. We argue that successful interventions will require the adoption of a socio-ecological model. This would ensure that the micro-, meso-, exo- and macrosystems required to support the behavioural, structural and biological interventions for promoting caries prevention are addressed. National oral health surveys are required to help understand the epidemiology, social determinants of and factors that undermine the ability of children to access oral health care. A global caries prevention agenda for children would help get the government's support for a national response agenda. Currently, there is no global call for action on the caries epidemic in children. This lack of an agenda needs to be urgently addressed. SUMMARY: A combination of approaches for the prevention of caries in children in Nigeria is needed. A national survey is needed to generate the needed evidence for the planning of community relevant responses to the national caries epidemic in children. The design of a global health agenda for children is an important first step that can facilitate the development of a national oral health programme for children in Nigeria.

RESUMEN

BACKGROUND: The objective of this paper is to draw attention to the oral health needs of children in Nigeria, and promote the use of appropriate interventions for disease prevention in the population. It also evaluates the value of the ongoing twice-daily tooth brushing campaign, which focuses on promoting good periodontal health and its relevance for children in Nigeria. DISCUSSION: The main oral health burden for children in Nigeria is untreated dental caries, attributable to low utilization of oral health facilities. While there is a strong association between oral hygiene status and caries occurrence, no research had established an association between frequency of tooth brushing and caries in children in Nigeria. Prevalence of caries and gingivitis is low, despite the fact that a majority of children brush once a day and most of them have fair oral hygiene. Campaigns that promote twice daily brushing to prevent chronic periodontitis in children are not driven by evidences supporting the local epidemic, and therefore cannot be considered as efficient use of the limited resources available. SUMMARY: Existing evidences show that the main oral health need of children in Nigeria is the management of untreated caries. Promoting the treatment of caries should be the primary focus of oral health programmes for children in Nigeria, as this would reduce further risks of developing new carious lesions. Public health campaigns should focus efforts at creating demand for oral health care services, for both preventive and curative purposes.

RESUMEN

Individuals with neurofibromatosis type 1 (NF-1), an autosomal dominant neurogenetic and tumor predisposition syndrome, are susceptible to developing low-grade glioma (LGG) and, less commonly, high-grade glioma (HGG). These gliomas exhibit loss of the neurofibromin gene (NF1), and 10-15% of sporadic HGG have somatic NF1 alterations. Loss of NF1 leads to hyperactive RAS signaling, creating opportunity given the established efficacy of MEK inhibitors (MEKi) in plexiform neurofibromas and some individuals with LGG. We observed that NF1-deficient glioblastoma neurospheres were sensitive to the combination of a MEKi (mirdametinib) with irradiation, as evidenced by synergistic inhibition of cell growth, colony formation, and increased cell death. In contrast, NF1-intact neurospheres were not sensitive to the combination, despite complete ERK pathway inhibition. No neurosphere lines exhibited enhanced sensitivity to temozolomide combined with mirdametinib. Mirdametinib decreased transcription of homologous recombination genes and RAD51 foci, associated with DNA damage repair, in sensitive models. Heterotopic xenograft models displayed synergistic growth inhibition to mirdametinib combined with irradiation in NF1-deficient glioma xenografts, but not those with intact NF1. In sensitive models, benefits were observed at least three weeks beyond the completion of treatment, including sustained phosphor-ERK inhibition on immunoblot and decreased Ki-67 expression. These observations demonstrate synergistic activity between mirdametinib and irradiation in NF1-deficient glioma models and may have clinical implications for patients with gliomas that harbor germline or somatic NF1 alterations.

RESUMEN

Antimicrobial resistance (AMR) is a growing problem in African cattle production systems, posing a threat to human and animal health and the associated economic value chain. However, there is a poor understanding of the resistomes in small-holder cattle breeds in East African countries. This study aims to examine the distribution of antimicrobial resistance genes (ARGs) in Kenya, Tanzania, and Uganda cattle using a metagenomics approach. We used the SqueezeMeta-Abricate (assembly-based) pipeline to detect ARGs and benchmarked this approach using the Centifuge-AMRplusplus (read-based) pipeline to evaluate its efficiency. Our findings reveal a significant number of ARGs of critical medical and economic importance in all three countries, including resistance to drugs of last resort such as carbapenems, suggesting the presence of highly virulent and antibiotic-resistant bacterial pathogens (ESKAPE) circulating in East Africa. Shared ARGs such as aph(6)-id (aminoglycoside phosphotransferase), tet (tetracycline resistance gene), sul2 (sulfonamide resistance gene) and cfxA_gen (betalactamase gene) were detected. Assembly-based methods revealed fewer ARGs compared to read-based methods, indicating the sensitivity and specificity of read-based methods in resistome characterization. Our findings call for further surveillance to estimate the intensity of the antibiotic resistance problem and wider resistome classification. Effective management of livestock and antibiotic consumption is crucial in minimizing antimicrobial resistance and maximizing productivity, making these findings relevant to stakeholders, agriculturists, and veterinarians in East Africa and Africa at large.

RESUMEN

Existing evidence from research supports the desirability of integration of mental health services into HIV care in order to mitigate the grave consequences of unattended mental health morbidity among People Living with HIV/AIDS (PLWHA). This study aims to find out the burden and pattern of psychiatric disorders that is prevalent among HIV-positive individuals attending a Nigerian-based HIV clinic. The study participants, consisting of 295 HIV-positive adults were recruited using systematic random sampling method. The participants were subjected to questionnaire to elicit demographic profile and General Health Questionnaire (GHQ-28) to screen for probable psychiatric disorders. This was followed by Structured Clinical Interview for DSM-IV Non patient (SCID-NP) to diagnose the presence of psychiatric morbidity in any of the participant with a GHQ-28 score ≥5 and 10% of those with GHQ-28 score <5. Data were analyzed with SPSS 17. Of the 295 participants interviewed, approximately one-quarter (25.1%) of the participants had diagnosable psychiatric illness based on SCID-NP. Depression was the commonest mental disorder detected as 44 (14.9%) met the DSM-IV Axis 1 diagnosis of major depressive disorders. Anxiety disorders, concurrent Nicotine with Alcohol dependence and cannabis abuse were elicited in 24 (8.1%), 4 (1.3%), and 2 (0.7%) participants, respectively. This study finds a higher burden of psychiatric disorders in PLWHA in comparison to what is obtainable in the general population based on previous research works in similar context. Thus further underscores the need for integration of comprehensive psychiatric services into HIV care. We advocate the support and commitment of key stakeholders in HIV care to the translation of this research-based evidence into practice among PLWHA.

RESUMEN

BACKGROUND: Hepatitis B virus infection is a priority job related disease that has both serious public and private health implications. Hepatitis B vaccine is the first anticancer vaccine that has outstanding record of safety and effectiveness and 95% effective in preventing children and adults from developing chronic infection. STUDY DESIGN/METHODOLOGY: The study design was a cross-sectional descriptive study. All the 88 health workers at the Lagos state accident and emergency centre who gave their consent to participate in the study were enrolled. Pre-tested, structured, self-administered questionnaire was used for data collection. RESULTS: Majority (70.2%) had good knowledge of hepatitis B infection and vaccination and the mean knowledge score (%) was 61.2 ± 20.7. Majority (90.4%) knew that hepatitis B virus can be acquired through a needle stick injury. Majority (67.9%) were aware of the existence of an effective vaccine against hepatitis B infection; however, only 45.1% knew correctly that a post hepatitis B vaccination test is necessary to confirm protection. Majority (86.9%) knew that a complete dose of hepatitis B vaccine is 95% effective; however, only 49.4% knew for how long the vaccine protects. Only 36.9% knew correctly that hepatitis B virus is 100 times more infectious than HIV. Attitude towards hepatitis B vaccination was good among all of the respondents and the mean attitude score (%) was 92.9 ± 14.3. Majority (84.5%) had poor practice of hepatitis B vaccination and the mean practice score (%) was 24.2 ± 25.0. Among those who did not receive the vaccine, majority (67.6%) gave non-availability of the vaccine as reason for this. CONCLUSION: The respondents had good knowledge and good attitude but poor practice of hepatitis B vaccination. There is therefore need to provide health workers with adequate information on blood-borne viruses in order to reinforce the knowledge and attitude which will eventually translate into a good practice of hepatitis B vaccination. A clear and concise immunization policies and effective monitoring should be put in place to ensure compliance at all government health facilities.

RESUMEN

AIMS AND OBJECTIVES - Pulse oximetry is mandatory during anaesthesia, sedation and transfer of critically ill patients. The effect of nail polish and acrylic nails on the accuracy of saturation reading is inconsistent. The Lifebox pulse oximeter is reliable and recommended for low and middle income countries. We investigated its accuracy in the presence of 4 nail colours and acrylic nails SUBJECTS AND METHODS Fifty non-smoking volunteers had their fingers numbered from right to left (little finger of right hand =1 and little finger of left hand =10). Alternate fingers were nails painted with clear, red, brown and black nail polish and the 5th finger had acrylic nail applied. The corresponding finger on the other hand acted as control. The oxygen saturation was determined using the Lifebox pulse oximeter. Results All fingers (100%) with clear nail polish, red nail polish and acrylic nails recorded a saturation value. Each of the mean saturation value for clear nail polish, red nail polish and acrylic nails was not significantly different from the control mean (p= 0.378, 0.427 and 0.921). Only 12% and 64% of nails polished black and brown respectively recorded a saturation value. The mean SpO- for black and brown polish were significantly different from their control mean (p<0.001). CONCLUSION Black and brown polish resulted in a significant decrease in SpO with the Lifebox oximeter. Dark coloured nail polish should be removed prior to SpO2 determination to ensure that accurate readings can be obtained.

RESUMEN

AIMS AND OBJECTIVES: To determine the knowledge, prevalence and psychological effect of miscarriage among women of reproductive age attending the obstetrics and gynaecology clinics of a tertiary healthcare facility in Lagos Nigeria. MATERIALS AND METHODS: Study design was a descriptive cross sectional study and 300 respondents were enrolled. A pre-tested interviewer-administered questionnaire and Multiple Affect Adjective Check List (MAACL) authored by M. Zukerman and B. Lubin (1965) were used for data collection. Responses of the respondents on the knowledge of various aspects of miscarriage was scored and graded as good (e"50%) and poor (^ <50%). The study was carried out in February 2011. RESULTS: Response rate was 97%. Only 0.7% of the respondents were not aware of miscarriage. A total of 214(73.5%) of the respondents had good knowledge of miscarriage and the mean knowledge score (%) was 60.4 ± 22.1. Most common myth about the cause of miscarriage among the respondents was eating of snail (63.2%). About 49% of respondents who had ever been pregnant have had miscarriage. Approximately 1 in 3.7 pregnancies was miscarried. The level of emotional distress in terms of anxiety, depression and hostility is significantly higher in women who have had miscarriage than their counterparts who had not. CONCLUSION: Level of knowledge of miscarriage was high though some miscarriage myths exist among the respondents. Approximately 1 in 3.7 pregnancies was miscarried. Miscarriage had negative psychological effect on women.

RESUMEN

BACKGROUND: Childhood obesity and associated hypertension are major public health concerns globally. This study aimed to determine the prevalence of obesity and the associated risk of high blood pressure among Nigerian adolescents. METHODS: A cross-sectional school-based study of 885 apparently healthy adolescents was performed. Weight, height and blood pressure (BP) were measured using standard methods. Body mass index (BMI) was calculated and categorized by age, sex and percentile. Obesity and overweight were defined as: ≥ 95th and 85th to < 95th percentiles, respectively, for age, sex and height. Subjects were sub-categorized into age 10-13 years (A) and 14-17 years (B). The odds ratio for pre-hypertensive and hypertensive range BP by age and BMI were generated. Significance was set at P < 0.05. RESULTS: The prevalence of overweight and obesity were 13.8% and 9.4%, respectively. The prevalence of hypertensive range systolic BP in obese versus normal BMI females was 16% versus 23% (p=0.00) and 12.1% versus 6.4% (p=0.27) in males. The prevalence of hypertensive range diastolic BP in obese versus normal BMI females was 12% versus 1.4% (p=0.00) and 15.2% versus 3.5% (p=0.01) in males. BMI in group B was significantly associated with pre-hypertensive and hypertensive range systolic BP in overweight (P = 0.01, P = 0.002) and obese subjects (P = 0.00, P = 0.00) and with hypertensive range diastolic BP (P = 0.00) only in obese subjects. The only significant association in group A was between obesity and pre-hypertensive range diastolic BP (P = 0.00). CONCLUSION: The prevalence of hypertensive range BP among obese Nigerian adolescents was high. Screening for childhood obesity and hypertension, and long-term follow-up of obese adolescents into adulthood are recommended.
