A Multicenter Retrospective Cohort Study of the Profile of Seminal Fluid Analyses of Men Seeking Fertility Care at Different Hospitals

BACKGROUND

Male infertility contributes 40 % of couple infertility. The prevalence of abnormal semen parameters has been on the increase. Age among other factors affects the fertility potential of males. This study analysed the pattern of seminal fluid parameters of males, seeking fertility treatment in hospitals and the relationship between age, volume and liquefaction time on these other semen parameters.

METHODS

This is a multicentre retrospective cohort study conducted in eight secondary and tertiary hospitals in Nigeria. The case notes of couples that sort fertility care at the Gynaecology and Urology clinics of these hospitals from January 1st 2022 to December 31st 2022 were retrieved after receiving ethical approval. A purposeddesigned proforma based on the WHO manual for the examination of human semen was used for data collection. Outcome measures were time of semen collection and examination, volume of semen, sperm number, sperm concentration, PH, agglutination, liquefaction, motility,morphology, vitality, and white blood cell count. Data was analysed using SPSS version 23. Data were presented as means and proportions. P-value of < 0.05 was used as the level of significance.

RESULTS

Overall, 1063 couples attended gynaecology and urology clinics with fertility-related concerns within the study period with a retrieval rate of 98.3%. The mean age of participants was 38.24 ± 8 years, while the mean semen volume and sperm concentrations were 2.62 ± 1.6 mls and 34.32 ± 7.4 million respectively. The age of participants significantly affected motility, volume and morphology (p-values of 0.001, 0.001 and 0.004 respectively). The total motility and sperm concentration have an inverse relationship with the age of the participants.

CONCLUSION

This study shows that sperm motility decreases with the age of participants. It was also observed that the most common combined abnormality was oligoasthenozoospermia.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

BACKGROUND

Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.

METHODS

This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries.

RESULTS

In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.

CONCLUSION

This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

PMON245 Clinical Phenotypes of Polycystic Ovary Syndrome (PCOS) in Nigerian Women: Preliminary Results of the Nigeria PCOS Epidemiology & Phenotype (Nigeria-Pep) Study

Background

Although the phenotype of polycystic ovary syndrome (PCOS) is heterogeneous, there is paucity of data on the prevalence and phenotype of PCOS in sub-Saharan Africa.

Methods

We studied 75 consecutive consenting women, aged 18-45 years, who presented with features suggestive of PCOS. A standardized proforma was used to obtain relevant information. Anthropometric measurements were determined, and terminal hair growth was assessed using the modified Ferriman-Gallwey (mF-G) method. All subjects underwent an oral glucose tolerance test (OGTT) and pelvic ultrasonography on day 2-7 of the menstrual cycle. An mF-G score of ≥ 6 was regarded as evidence of clinical hyperandrogenism (HA). Menstrual dysfunction (MD) was defined as menstrual cycle lengths >35 or <25 days. Polycystic Ovarian Morphology (PCOM) was defined as an antral follicle count (AFC) of ≥12 2-9 mm follicles and/or an ovarian volume ≥10 cm3, in at least one ovary.

Results

The mean (SD) age of the study population was 28.6 (5.8) years, and the mean (SD) body mass index (BMI) was 26.3 (5.6) kg/m2. Three (4.0%) participants were underweighted, 27 (36.0%) had normal BMI, 30 (40%) were overweight, and 15 (20.0%) were obese. The mean (SD) systolic and diastolic blood pressures were 107.4 (12.6) mmHg and 72.6 (8.2) mmHg, respectively. OGTT results indicated that the mean (SD) fasting blood glucose was 86.6 (10.6) mg/dl and the mean (SD) 2-hr. postprandial glucose was 109.8 (22.2) mg/dl. Two women had impaired glucose tolerance and one had type 2 diabetes mellitus. Of the 75 subjects recruited, 26 (34.7%) had HA, 54 (72.0%) had MD, and 63 (84.0%) had PCOM. Of all subjects, 20 (26.7%) had HA+MD+PCOM, consistent with PCOS Phenotype A; one (1.3%) had HA+MD only, consistent with Phenotype B; four (5.3%) had HA+PCOM only, consistent with Phenotype C; and 28 (37.3%) had MD+PCOM only, consistent with Phenotype D. In 22 (29.4%) no evidence of PCOS was found. Overall, our results indicate that of subjects evaluated clinically, 53 (70.6%) had PCOS.

Conclusions

Our preliminary results indicate that in a referral (clinical) population in Lagos, Nigeria, using only the clinical presentation without circulating androgen measures, PCOS was detected in two-thirds, with Phenotype D (aka, 'non-hyperandrogenic PCOS’) being the most common presentation (53%), followed by Phenotype A (aka 'classic or full PCOS’) observed in 38% of all women with PCOS seen. However, as 72% of all subjects had MD and 63% had PCOM, many more of these women could have been diagnosed with PCOS if the presence of hyperandrogenemia could have been demonstrated. Overall, these observations suggest that accurate measurement of circulating androgen, lacking in many parts of Sub-Sahara Africa, may be critical to accurately detecting PCOS in that region. Studies are ongoing.

Seroprevalence of Hepatitis B, and C Viruses and HIV Infections among Antenatal Women in a Secondary Health Facility in Lagos, Nigeria

BACKGROUND

Hepatitis B and C viruses and HIV infections contribute a significant proportion to maternal and perinatal morbidity and mortality in low and middle-income countries. While the burden of hepatitis B and C viruses is higher in low and middle-income countries, Nigeria also has the second largest burden of HIV.

OBJECTIVES

To determine the seroprevalence of hepatitis B and C viruses and HIV infections among antenatal women who sought care at a secondary health facility in Lagos.

METHODS

This was a retrospective review of patients managed in the antenatal clinic of 68 Nigerian Army Reference Hospital over one year. A study proforma was used to collect relevant data which were entered and analyzed using the IBM Statistical Package for Social Sciences (SPSS Statistics) Version 23.

RESULTS

A total of 347 women attended prenatal care during the study period, however, only 329 cases with complete data were included in the final statistical analysis. The prevalence of HIV in our study was 6.4%, while HBV and HCV accounted for 6.2% and 1.8% respectively. Hepatitis B, and hepatitis C viruses and HIV Infections occurred in 3 (0.9%) of our patients, 6 (1.8%) of the women had HIV-HBV co-infection while 1 (0.3%) was infected with HIV-HCV.

CONCLUSION

Our study re-emphasizes the public health importance of HBV, HCV and HIV screening in our antenatal clinics. This knowledge is very important for the implementation of effective prevention and control measures that will further decrease the mother-to-child transmission of these viruses.

Use of exchange blood transfusion in the management of severe COVID-19 infection in pregnancy: experience from Lagos, Nigeria

Coronavirus disease 2019 (COVID-19) presents with symptoms that may be mild or severe. The individual with the severe form of the disease usually presents with a constellation of respiratory symptoms typical of acute respiratory distress syndrome. In this report, we present our experience of the successful management of an oxygen-dependent pregnant woman with severe COVID-19 infection who had 2 sessions of partial exchange blood transfusion. We discussed the principles that informed this intervention and the need to adopt this novel approach in the care of severe COVID-19 infection.

Maternal Outcomes of Eclampsia at the Lagos University Teaching Hospital: A Six-Year Retrospective Review

BACKGROUND

Eclampsia is one of the leading causes of maternal morbidity and mortality.

OBJECTIVES

To determine the incidence as well as the maternal outcomes of eclampsia at the Lagos University Teaching Hospital (LUTH).

METHODS

This was a retrospective review.

RESULTS

During the six-year review period, 4182 women gave birth at our facility, out of which 67 cases of eclampsia were diagnosed (16 per 1000 deliveries). Four women died constituting a case fatality rate of 5.9%. Fifteen women were admitted to the intensive care unit, 6 women had acute kidney injury while 5 had abruptio placentae. Further comparison of our data with previous studies from our institution decades ago showed a continuous decrease in total number of eclamptic cases presenting to our facility (572 eclamptics in 1977 - 1986, 299 ECLAMPTICS IN 1986 - 1995, 165 IN 1996-2005 AND 67 IN 2015-2020).

CONCLUSION

The case fatality rate from eclampsia is still high in our hospital. Increased utilisation of antenatal care may play an important role in improving the maternal outcomes from this life-threatening obstetric condition. There is need for maternal education and increase awareness on the importance of antenatal care and early referral to tertiary level of care in order to reverse this trend.

Ovarian reserve in nigerian women with sickle cell anaemia: a cross- sectional study

INTRODUCTION

Sickle cell disease is the most common monogenetic disorder worldwide. There have been reports of endocrine dysfunction and gonadal failure among affected individuals, especially in males. The findings on ovarian reserve and failure in women with sickle anaemia have been inconsistent.

AIM AND OBJECTIVE

The aim of this study was to determine and compare the ovarian reserve of Nigerian women with and without sickle cell anaemia attending a University Teaching Hospital.

STUDY DESIGN

This cross-sectional study was carried out at the Adult Sickle Cell Clinic and the Community Health Clinic of the Lagos University Teaching Hospital.

METHODOLOGY

A total of 166 participants who met the selection criteria, were recruited for the study. The study population consisted of two groups of women matched for age: 83 women with HbSS and 83 women with HbAA. The haemoglobin phenotype of each participant was determined on alkaline electrophoresis (pH 8.4) before analysis. Serum Anti-Mullerian Hormone (AMH) was determined using Enzyme-linked immunosorbent assay (ELISA) method (Calbiotech Inc. USA, Catalog no AM448T).

RESULTS

The mean ± SD of serum AMH level in women with HbSS was 3.64 ± 0.65 ng/mL and was lower than that of women with HbAA 7.35 ±1.19 ng/mL (p < 0.001). Serum AMH negatively correlated with age in both study groups (HbAA and HbSS). Also, a significant negative correlation was found between serum AMH and BMI in women with HbAA.

CONCLUSION

The study showed diminished ovarian reserve in women with HbSS when compared to age-matched women with HbAA.

Reproductive Maternal and Newborn Health Providers' Assessment of Facility Preparedness and Its Determinants during the COVID-19 Pandemic in Lagos, Nigeria

The global COVID-19 pandemic is predicted to compromise the achievement of global reproductive, maternal, and newborn health (RMNH) targets. The objective of this study was to determine the health facility (HF) preparedness for RMNH service delivery during the outbreak from the perspective of RMNH providers and to determine what factors significantly predict this. An anonymous cross-sectional online survey of RMNH providers was conducted from to July 1–21, 2020 in Lagos State, Nigeria. We conducted a descriptive and ordinal regression analysis, with RMNH worker perception of HF preparedness for RMNH service delivery during the outbreak as the dependent variable. In all, 256 RMNH workers participated, 35.2% reported that RMNH services were unavailable at some time since March 2020, 87.1% felt work-related burnout, 97.7% were concerned about the availability of personal protective equipment (PPE) and related guidelines, and only 11.7% were satisfied with the preparedness of their HFs. Our final model was a statistically significant predictor of RMNH worker perception of HF preparedness explaining 54.7% of the variation observed. The most significant contribution to the model was communication by HF management (likelihood ratio chi-square [LRCS]: 87.94, P < 0.001) and the availability of PPE and COVID-19 guidelines (LRCS: 15.43, P < 0.001). A one-unit increase in the level of concern about the availability of PPE and COVID-19 guidelines would increase the odds of observing a higher category of satisfaction with HF COVID-19 preparedness. Adequate support of RMNH providers, particularly provision of PPE and guidelines, and appropriate communications about COVID-19 should be prioritized as part of HF preparedness.

Hysterosalpigography findings of female partners of infertile couple attending fertility clinic at Lagos University Teaching Hospital

Introduction

Hysterosalpingography (HSG) is an outpatient fluoroscopic method for the evaluation of the uterine cavity, fallopian tubes, and the surrounding peritoneal cavity. Female fertility depends greatly on normal female reproductive organs; hence tubal abnormalities may contribute significantly to female infertility. HSG is an invaluable screening tool in the evaluation of women with suspected tubal factor infertility. This study aims to review the HSG findings of women who sought fertility treatment at the Lagos University Teaching Hospital, Lagos (LUTH).

Methods

this was a retrospective study of the pattern of HSG findings among female partners of infertile couples seeking fertility treatment at the LUTH, over a 2-year period, from January 2018 to December 2019.

Results

a total of 266 medical records and HSG results were reviewed and included in the data analysis. The mean age (± standard deviation) was 38.4 (± 0.3) years with a range of 24 to 50 years. Most (80.5%) of the participants have secondary infertility and majority (65.4%) were nulliparous. Tubal pathology was the commonest abnormality detected on HSG in 54.9% of women. About one-third (30.8%) of women had bilateral tubal occlusion on HSG. With regards to the right fallopian tube, 43.2% of the participants had tubal occlusion, which differs from 41.7% on the left fallopian tube. Similarly, 10.2% of the women had hydrosalpinx on the left tube when compared with 9% on the right tube. Age (OR 1.055; 95% CI: 1.006, 1.106, p-value 0.028), and previous salpingectomy [OR 6.151; 95% CI: 1.335, 28.349] and myomectomy [OR 4.6; 95% CI: 1.814, 11.67] were identified as risk factors for tubal pathologies on HSG.

Conclusion

tubal abnormalities are common findings on HSG and the identifiable risk factors for tubal pathologies include age, salpingectomy, and myomectomy. HSG remains a vital screening tool in the evaluation of tubal-factor infertility in Nigeria.

Utilization cost of maternity services for childbirth among pregnant women with coronavirus disease 2019 in Nigeria's epicenter

OBJECTIVE

To estimate utilization costs of spontaneous vaginal delivery (SVD) and cesarean delivery (CD) for pregnant women with coronavirus disease 2019 (COVID-19) at the largest teaching hospital in Lagos, the pandemic's epicenter in Nigeria.

METHODS

We collected facility-based and household costs of all nine pregnant women with COVID-19 managed at the hospital. We compared their mean facility-based costs with those paid by pregnant women pre-COVID-19, identifying cost-drivers. We also estimated what would have been paid without subsidies, testing assumptions with a sensitivity analysis.

RESULTS

Total utilization costs ranged from US $494 for SVD with mild COVID-19 to US $4553 for emergency CD with severe COVID-19. Though 32%-66% of facility-based cost were subsidized, costs of SVD and CD during the pandemic have doubled and tripled, respectively, compared with those paid pre-COVID-19. Of the facility-based costs, cost of personal protective equipment was the major cost-driver (50%). Oxygen was the major driver for women with severe COVID-19 (48%). Excluding treatment costs for COVID-19, mean facility-based costs were US $228 (SVD) and US $948 (CD).

CONCLUSION

Despite cost exemptions and donations, utilization costs remain prohibitive. Regulation of personal protective equipment and medical oxygen supply chains and expansion of advocacy for health insurance enrollments are needed in order to minimize catastrophic health expenditure.

Caesarean delivery of first prediagnosed COVID-19 pregnancy in Nigeria

The COVID-19 pandemic is currently causing widespread infection and deaths around the world. Since the identification of the first case in Nigeria in February 2020, the number of confirmed cases has risen to over 9,800. Although pregnant women are not necessarily more susceptible to infection by the virus, changes to their immune system in pregnancy may be associated with more severe symptoms. Adverse maternal and perinatal outcomes have been reported among pregnant women with COVID-19 infection. However, literature is scarce on the peripartum management and pregnancy outcome of a pregnant woman with COVID-19 in sub-Saharan Africa. We report the first successful and uncomplicated caesarean delivery of a pregnant woman with COVID-19 infection in Nigeria.

Management of covid-19: a practical guideline for maternal and newborn health care providers in Sub-Saharan Africa

COVID-19 is a pandemic that is currently ravaging the world. Infection rate is steadily increasing in Sub-Saharan Africa. Pregnant women and their infants may suffer severe illnesses due to their lower immunity. This guideline prepares and equips clinicians working in the maternal and newborn sections in the sub-region to manage COVID-19 during pregnancy and childbirth.

Methylene tetrahydrofolate reductase and methionine synthase gene polymorphisms as genetic determinants of pre-eclampsia

BACKGROUND

Pre-eclampsia (PE) is a leading cause of maternal and neonatal mortality in Africa; and has been associated with the interplay of genetic, metabolic and environmental factors. Polymorphisms of methylene tetrahydrofolate reductase (MTHFR) and methionine synthase (MTR) folate cycle genes, have been controversially associated with pre-eclampsia in studies from different human populations.

OBJECTIVES

To determine the distribution of MTHFR C677T and MTR A2756G polymorphisms in a Nigerian population and evaluate possible associations with the occurrence of pre-eclampsia and homocysteine metabolic derangement.

MATERIALS AND METHODS

This study was a hospital based study carried out in Lagos, South-western Nigeria. Two hundred pregnant women clinically diagnosed with pre-eclampsia (study group) and 200 apparently healthy non-pre-eclamptic pregnant women (control group) were recruited for the study after written informed consent. Pre-eclampsia was diagnosed based on the International Society for the Study of Hypertension in Pregnancy re-classification of 2013. MTHFR C677T and MTR A2756G polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Statistical analyzes were performed using SPSS version 23. Hardy-Weinberg distribution were tested with χ2 test. Logistic regression model was used to evaluate the relationship of variables with pre-eclampsia. A value of p < 0.05 was considered statistically significant.

RESULTS

MTHFR genotype frequencies of CC, CT and TT were 59.8%; 31.2% and 9.0% in study group and 76.6%; 22.3% and 1.0% in the control group respectively. MTR A2756G genotype frequencies of AA, AG and GG genotypes were 71.9%; 20.1% and 8.0% for the study group and 81.5%; 16.4% and 2.1% for the control group. Occurrence of pre-eclampsia was significantly associated with presence of T allele of MTHFR (OR = 1.855; p < 0.05) and G allele of MTR genes (OR = 1.269; p < 0.05), Homozygosity of TG haplotype significantly increased the occurrence of pre-eclampsia among Nigerian women (OR = 2.252; p < 0.05). Population attributable risk fraction percent for the T and G alleles were 16.4% and 11.5% respectively. Mean plasma Hcy level was not, however, significantly affected by MTHFR/MTR haplotypes (F = 1.54; p = 0.157).

CONCLUSION

MTHFR C677T and MTR A2756G polymorphisms were associated with pre-eclampsia in a population of pregnant women in Lagos, Nigeria.

A prospective cohort study on the clinical utility of second trimester mean arterial blood pressure in the prediction of late-onset preeclampsia among Nigerian women

BACKGROUND

Early detection of preeclampsia will help reduce the morbidities and mortalities associated with the disorder. Late-onset preeclampsia was the predominant presentation in this cohort. The search for biomarkers for predicting preeclampsia is still ongoing. Mean arterial blood pressure (MABP), which has the advantage of presenting a single cutoff value compared with the use of systolic and diastolic blood pressure measurements, merits evaluation.

AIM

The study aims to evaluate the clinical utility of second trimester MABP in the prediction of preeclampsia.

METHODS

This was a prospective cohort study of 155 normotensive, nonproteinuric pregnant women without prior history of gestational hypertension. The women were booked patients attending the antenatal clinic at the Lagos University Teaching Hospital and were all in their second trimesters of pregnancy. The outcome measures were systolic blood pressure, diastolic blood pressure, and MABP. The end point of the study was the development of preeclampsia. The diagnosis of preeclampsia was made by the attending obstetrician. The data were analyzed using the IBM SPSS statistical software. Statistical significance was set at P < 0.05.

RESULTS

One hundred and fifty-five pregnant women participated in the study. Eleven (7.1%) of the women developed preeclampsia after 34 weeks gestation and 144 (92.9%) had normal pregnancy. The mean gestational age at the time of assessment was 18.88 ± 3.15 weeks with a range of 14 weeks to 27 completed weeks. There was a statistically significant increase in the systolic blood pressure, diastolic blood pressure, and MABP values in the group of women who later developed preeclampsia, P = 0.005, 0.001, and <0.001, respectively. At a false-positive rate of 10%, MABP value of 88.33 mmHg predicted preeclampsia with a specificity of 90% and a sensitivity of 45.5%, P <0.05. The area under the receiver-operative characteristics curve (AUC) was 0.732 (95% confidence interval, 0.544-0.919, P = 0.011). The negative predictive value (NPV) was 88.88% and the positive predictive value (PPV) was 45.45%, P < 0.05. At an MABP cutoff of 88.33 mmHg, preeclampsia was predicted with a relative risk of 4.44 and a positive likelihood ratio of 6.46, P < 0.05.

CONCLUSIONS

With an AUC of 0.732, MABP performed moderately (considering that excellent performance has an AUC of 1.0) in the prediction of late-onset preeclampsia in Nigerian women. Its high NPV suggests a strong ability to rule out preeclampsia and help to appropriate management.

Early pregnancy plasminogen activator inhibitor-1 levels in Nigerian women and its relationship with preeclampsia

AIM

This study compared early plasma levels of plasminogen activator inhibitor-1 (PAI-1) in normal pregnancy and preeclampsia and determined its relationship with disease severity.

SUBJECTS AND METHODS

This was a prospective cohort study of 195 normotensive, aproteinuric pregnant women without prior history of gestational hypertension. The women were attending the Antenatal Clinic at The Lagos University Teaching Hospital and were within 24 weeks gestation at recruitment. The outcome measures were PAI-1, systolic blood pressure (SBP), diastolic blood pressure (DBP), and significant proteinuria. The endpoint of the study was the development of preeclampsia. The diagnosis of preeclampsia was made by the attending Obstetrician. The data were analyzed using the IBM SPSS statistical software. Statistical significance was set at P < 0.05.

RESULTS

First trimester PAI-1 levels were significantly higher in the women who later developed preeclampsia compared to those who had a normal pregnancy (P < 0.0001). In these group of women who later developed preeclampsia, PAI-1 had an inverse relationship with gestational age (r = 0.878) whereas in normal pregnancy, PAI-1 and gestational age had a direct relationship (r = 0.017). Second trimester systolic and DBP values were also significantly higher in the women who later developed preeclampsia compared to normal pregnancy, P = 0.007 and 0.004, respectively. There was, however, no correlation between PAI-1 values and SBP, DBP and proteinuria in the women who developed preeclampsia.

CONCLUSION

Plasma levels of PAI-1 are increased early in pregnancies complicated by preeclampsia, but the lack of correlation of this marker with disease severity may limit its clinical utility.

Selenium status and infant birth weight among HIV-positive and HIV-negative pregnant women in Lagos, Nigeria

BACKGROUND

During pregnancy, selenium deficiency and reduced antioxidant activities may result in adverse perinatal outcome such as low birthweight, which is associated with significant perinatal morbidity and mortality. Many studies have reported conflicting findings on the relationship between maternal selenium status and infant birth weight.

OBJECTIVE

This study is to determine the relationship between maternal serum selenium concentration and infant birthweight in HIV-positive and HIV-negative pregnant women at term.

METHODS

A cross-sectional study carried out among HIV-positive and HIV-negative pregnant women at term. Participants were recruited from the antenatal clinic at the Lagos University Teaching Hospital. After obtaining an informed consent, participants were interviewed using a structured questionnaire. Five milliliters of venous blood sample was collected from each participant for estimation of selenium levels using the Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. At delivery, the infant birth weights were measured using a standard infant weighing scale.

RESULTS

Of the 240 participants, data were complete for analysis in 214 (89.2%) of the participants. HIV-positive women had significantly lower mean serum selenium concentration when compared with HIV-negative women (33.7 +/- 22.2 pg/L versus 83.6 +/- 18.7 pg/L; p<0.01). Compared with HIV-negative women, the mean birth weight of infants of HIV positive women was significantly lower (2952 +/- 572 g versus 3392 +/- 452 g; p<0.01). There was no significant association between maternal serum selenium levels at term and infant birth weight in both groups.

CONCLUSION

HIV-positive pregnant women had a lower mean serum selenium level and their infants had a lower mean birth weight, when compared to HIV-negative pregnant women. However, no significant association was found between maternal serum selenium concentration and birth weight in both groups.

The role of cytokines as inflammatory mediators in preeclampsia

Introduction

This study is to determine the concentrations of IL-6, TNF α, and C reactive protein (CRP) in women with severe preeclampsia, and compare with those of gestational age- matched normotensive pregnant women and to correlate CRP levels with markers of organ damage in women with preeclampsia.

Methods

This was a case control study of fifty women with severe preeclampsia and fifty gestational age matched pregnant women with normal blood pressure. The women were drawn from The Antenatal Clinic of The Lagos University Teaching Hospital. Severe pre eclampsia was defined as systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥110mmHg and ≥2+ of proteinuria. After obtaining an informed consent, each participant completed a structured questionnaire. The questionnaire sought information on socio-demographic and clinical data. From each participant, mid-stream urine was collected for urinalysis and culture, and blood sample was collected for biochemical analysis. Comparisons of continuous variables and categorical variables were done using the Student's t test and Chi square test respectively. Correlation analysis was used to determine the associations between variables. Statistical significance was set at P

Results

The women were similar in their socio demographic characteristics. There was a statistically significant difference in the systolic blood pressure (p < 0.0001), diastolic blood pressure ( p < 0.0001), uric acid ( p < 0.0001), AST ( p < 0.0001), ALP ( p < 0.0001), creatinine ( p < 0.0013), GGT ( p < 0.005), IL 6 ( p < 0.021), CRP ( p < 0.0002), and TNF α ( p < 0.023), between the group with severe preeclampsia and the group with normal blood pressure. This study also reports a significant association between CRP and systolic blood pressure, diastolic blood pressure, uric acid AST and ALP (p

Conclusion

The inflammatory cytokines, IL6, TNF α and CRP are elevated in severe preeclampsia and may mediate some of the clinical manifestations of the disorder. A role may exist for anti inflammatory agents in the management of women with preeclampsia.

What do medical interns in Nigeria think of the white coat? A cross sectional study

BACKGROUND

The appeal of the white coat to both the doctors and the public is waning. In most developing countries such as Nigeria doctors' view of the white coat is not known.

OBJECTIVE

To determine the proportion of interns which supported wearing of white coat by doctors.

METHODS

A 10-item questionnaire was distributed to medical interns undertaking mandatory pre-registration training in a tertiary hospital. Characteristics of interns who were supportive of doctors wearing the white coat were compared to those who did not support or were indifferent to it.

RESULTS

Two hundred and thirty three interns returned completed questionnaires. About 54% (126) and 52% (107) of the participants were males and graduates of the College of Medicine, University of Lagos respectively. The majority of interns (167; 71.7%) supported the wearing of white coats by doctors when attending to patients; 22 (9.4%) were opposed to it while 44 (18.9%) were indifferent. Older interns, females and interns who had not rotated through Paediatrics were more likely to support the wearing of white coats by doctors. The commonest reason for wearing the white coat was for identification.

CONCLUSION

The majority of medical interns supported the wearing of white coat by doctors. Prevention of infection is no longer the major reason for wearing the white coat. There is need to document the public's perception of the white coat.

Human papillomavirus (HPV) infection and vaccines: knowledge, attitude and perception among female students at the University of Lagos, Lagos, Nigeria

Aim: This study sought to determine knowledge of and attitude towards human papillomavirus (HPV) infection, HPV-related diseases and HPV vaccines among female undergraduate students at the University of Lagos.

Methods: A self-administered questionnaire was administered between May and July 2010, to 368 female students aged 16–29 years, who were selected from two faculties of the University of Lagos using two-stage sampling method. Data collected included: socio-demographic characteristics, sexual history, awareness and knowledge of HPV infection, cervical cancer and genital warts, and HPV vaccine; the perceived risk of acquiring genital HPV infection and developing cervical cancer or genital warts, and the willingness to receive an HPV vaccine.

Results: Only 64 (17.7%) and 52 (14.4%) of the students had ever heard of HPV infection and HPV vaccines respectively. The median HPV knowledge on a 15-item score was 2. Overall, only 11.1% knew that genital HPV infection can cause cervical cancer. Fourteen (6.9%) of those who were aware of cervical cancer agreed they were at risk of developing the disease. Of the 52 students who had heard of the HPV vaccine, 24 (46.2%) knew it was given for cervical cancer prevention and 30 (57.7%) expressed their willingness to receive the vaccine.

Conclusion: The knowledge of and the perceived susceptibility to HPV infection and HPV-related diseases among female students in the University of Lagos were generally low. The need for a well-designed HPV-educational program to bridge the knowledge gap cannot be overemphasized.

Knowledge of and attitude toward human papillomavirus infection and vaccines among female nurses at a tertiary hospital in Nigeria

Background

Persistent infection with high-risk types of human papillomavirus (HPV) is a prerequisite for the development of cervical cancer. Highly immunogenic HPV vaccines have been developed and licensed for the primary prevention of cervical cancer in some developed and developing countries. This calls for assessment of the knowledge of the HPV infection and the acceptability of the HPV vaccines among health care providers.

Objective

The aim of this study was to assess awareness and knowledge of HPV infection and vaccines and to assess attitude toward these vaccines among female nurses at Lagos University Teaching Hospital, Lagos, Nigeria.

Study design

The study was a cross-sectional, descriptive study using a pretested, structured, anonymous, self-administered, 19-item questionnaire.

Results

A total of 178 female nurses were interviewed during a 4-week period. The mean age of respondents was 37.1 ± 3.1 years. Almost all (99.4%) of the respondents had heard of cervical cancer, while about 85% of them had heard of HPV infection. Only a quarter (25.3%) of respondents had heard of the HPV vaccines, and of those only 26.7% knew the vaccines were for the prevention of cervical cancer. Most (70.2%) of the nurses expressed a desire to be vaccinated and 120 (67.4%) supported the vaccination of preadolescent girls. Those who expressed a willingness to be vaccinated were more likely to recommend HPV vaccination for preadolescent girls.

Conclusion

Overall, there was a poor knowledge of the HPV vaccines among female nurses at Lagos University Teaching Hospital. Despite this poor knowledge, most of the nurses expressed a strong desire to be vaccinated and their intention to recommend it for preadolescent girls. The main reason given overall for not recommending the vaccines was lack of information. There is an urgent need to bridge this information gap.
