Health system constraints affecting treatment and care among women with cervical cancer in Harare, Zimbabwe.

BACKGROUND: Cervical cancer is a major cause of morbidity and mortality among women yet access to treatment and care remains a huge challenge in Zimbabwe. The objective of this study was to investigate health system constraints affecting engagement into treatment and care by women with cervical cancer in Harare, Zimbabwe. METHODS: A sequential explanatory mixed methods design was used for this study. Phase 1 comprised of two surveys namely: patient and health worker surveys with sample sizes of 134 and 78 participants respectively. Validated structured questionnaires programmed in Android tablet with SurveytoGo software were used for data collection during the surveys. Univariate analyses were conducted using STATA® version 14 to generate descriptive statistics. In phase 2, 16 in-depth interviews, 20 key informant interviews and 6 focus groups were conducted to explain survey results. Participants were purposively selected and sample sizes were informed by saturation principle. Participants in phase 1 and 2 were different. English transcripts were manually coded line by line in Dedoose software using the thematic codes that had been established from the survey data. The final codes were used to support and explain the survey data at the interpretation stages. RESULTS: Health system constraints identified in surveys were: limited or lack of training for health workers, weakness of surveillance system for cervical cancer, limited access to treatment and care, inadequate health workers, reliance of patients on out-of-pocket funding for treatment services, lack of back-up for major equipment. Qualitative inquiry revealed the following barriers to treatment and care: high costs of treatment and care, lack of knowledge about cervical cancer and bad attitudes of health workers, few screening and treating centres located mostly in urban areas, lack of clear referral system resulting in bureaucratic processes, and limited screening and treating capacities in health facilities due to lack of resources. CONCLUSION: The results of this study show that health system and its organization present barriers to access of cervical cancer treatment and care among women. Strong political will, mobilization of resources both domestically and from partners in addition to sound policies are imperative to address key health system challenges.

Cervical cancer knowledge, attitudes, beliefs and practices of women aged at least 25 years in Harare, Zimbabwe.

BACKGROUND: Cervical cancer is the most common cancer and a major cause of morbidity and mortality among women in Zimbabwe yet it is preventable, early detectable and highly curable. The objective of this study was to investigate knowledge, attitudes, beliefs and practices towards cervical cancer, its prevention and treatment in Harare, Zimbabwe. METHODS: Sequential explanatory mixed methods approach consisting of analytical cross sectional survey and a qualitative inquiry was used. Study population consisted of women with cervical cancer, health workers and other stakeholders who are involved in cancer control programmes. Patient survey data were collected using validated structured questionnaire in Surveytogo software in an android tablet. Qualitative study used key informant interviews to understand survey findings better. Data analyses for the survey involved univariate and multivariate analyses using STATA version 14. For qualitative study, themes in transcripts were coded and analyzed using Dedoose software to generate evidence for the study. RESULTS: Participants reported different levels of knowledge of causes (23%), risk factors (71%), prevention (72%), screening (73%) and treatment (80%) of cervical cancer. Knowledge of causes of cervical cancer were negatively associated with: being aged 45 or more years (OR = 0.02; p = 0.004), having no household income (OR = 0.02;p = 0.007), household income

Determinants of access and utilization of cervical cancer treatment and palliative care services in Harare, Zimbabwe.

BACKGROUND: Cervical cancer treatment and care services have remained largely centralized in Zimbabwe thereby entrenching inequities to access amongst patients. The objective of this study was to investigate the determinants of access to treatment and care among women with cervical cancer in Harare, Zimbabwe. METHODS: A sequential explanatory mixed methods design was used. In phase 1, three surveys (namely community, patient and health worker) were conducted with sample sizes of 143, 134 and 78 participants respectively. Validated structured questionnaires programmed in Android tablet with SurveytoGo software were used for data collection during the surveys. Univariate, bivariate and multivariate logistic regression analyzes were conducted using STATA® version 14 to generate descriptive statistics and identify determinants of access to cervical cancer treatment and care. In phase 2, 16 in-depth interviews, 20 key informant interviews and 6 focus groups were conducted to explain quantitative data. Participants were purposively selected and saturation principle was used to guide sample sizes. Manually generated thematic codes were processed in Dedoose software to produce final outputs for qualitative study. RESULTS: Knowledge of causes (p = 0.046), perceptions of adequacy of specialists (p < 0.001), locus of control (p = 0.009), service satisfaction (p = 0.022) and walking as a means of reaching nearest health facilities (p < 0.001) were associated with treatment or perceptions of access by healthy women. Perceptions of access to treatment amongst health workers were associated with their basic training institution (p = 0.046), health service quality perceptions (p = 0.035) and electricity supply status in their respective health facilities (p = 0.036).Qualitative findings revealed health system, societal and individual factors as barriers to accessing treatment and palliative care. CONCLUSIONS: There are numerous prevailing multi-dimensional barriers to accessing cervical cancer treatment and palliative care in a low -income setting. The findings of this study revealed that heath system and societal factors were more important than individual level factors. Multi-sectoral approaches are recommended to address all the multifaceted barriers in order to improve cervical cancer treatment and palliative care access for better outcomes in resource-limited contexts.

Sociodemographic inequities in cervical cancer screening, treatment and care amongst women aged at least 25 years: evidence from surveys in Harare, Zimbabwe.

BACKGROUND: Cervical cancer is the most commonly diagnosed cancer among women in Zimbabwe; however; access to screening and treatment services remain challenged. The objective of this study was to investigate socio-demographic inequities in cervical cancer screening and utilization of treatment among women in Harare, Zimbabwe. METHODS: Two cross sectional surveys were conducted in Harare with a total sample of 277 women aged at least 25 years. In the community survey, stratified random sampling was conducted to select 143 healthy women in Glen View, Cranborne, Highlands and Hopely communities of Harare to present high, medium, low density suburbs and rural areas respectively. In the patient survey, 134 histologically confirmed cervical cancer patients were also randomly selected at Harare hospital, Parirenyatwa Hospital and Island Hospice during their routine visits or while in hospital admission. All consenting participants were interviewed using a validated structured questionnaire programmed in Surveytogo software in an android tablet. Data was analyzed using STATA version 14 to yield descriptive statistics, bivariate and multivariate logistic regression outcomes for the study. RESULTS: Women who reported ever screening for cervical cancer were only 29%. Cervical cancer screening was less likely in women affiliated to major religions (p < 0.05) and those who never visited health facilities or doctors or visited once in previous 6 months (p < 0.05). Ninety-two (69%) of selected patients were on treatment. Women with cervical cancer affiliated to protestant churches were 68 times [95% CI: 1.22 to 381] more likely to utilize treatment and care services compared to those in other religions (p = 0.040). Province of residence, education, occupation, marital status, income (personal and household), wealth, medical aid status, having a regular doctor, frequency of visiting health facilities, sources of cervical cancer information and knowledge of treatability of cervical cancer were not associated with cervical cancer screening and treatment respectively. CONCLUSION: This study revealed few variations in the participation of women in cervical cancer screening and treatment explained only by religious affiliations and usage of health facilities. Strengthening of health education in communities including churches and universal healthcare coverage are recommended strategies to improve uptake of screening and treatment of cervical cancer.

Assisted reproductive technology and severe postpartum haemorrhage: a case-control study.

OBJECTIVE: To investigate the association between assisted reproductive technology and severe postpartum haemorrhage. DESIGN: Case-control study. SETTING: The study was conducted in Norway; Division of Gynaecology and Obstetrics at Oslo University Hospital and Department of Obstetrics and Gynaecology at Drammen Hospital. POPULATION: A source population including all women admitted for delivery at Oslo University Hospital and Drammen Hospital during the time period 1 January 2008 to 31 December 2011. The study population consisted of all cases of severe postpartum haemorrhage (n = 1064) and a random sample of controls (n = 2059). METHODS: We used an explanatory strategy in the analysis, with multivariable logistic regression. MAIN OUTCOME MEASURES: Severe postpartum haemorrhage; defined as blood loss ≥1500 ml or need for blood transfusion. RESULTS: Assisted reproductive technology was associated with an increased risk of severe postpartum haemorrhage (crude OR = 2.92; 95% CI 2.18-3.92, P < 0.001). Mode of delivery and anticoagulant medication had significant confounding effects. Strong interaction was found for multiple pregnancies. After adjusting for confounding and interaction, an increased risk was observed both in the strata of multiple pregnancies (adjusted OR = 7.00, 95% CI 2.70-18.12, P < 0.001), and in the strata of single gestation (adjusted OR = 1.58, 95% CI 1.12-2.24, P = 0.010). CONCLUSIONS: Our findings warrant an increased awareness of the risk of severe postpartum haemorrhage in women conceiving with assisted reproductive technology. Furthermore, the high risk of severe postpartum haemorrhage in the presence of a twin or triplet pregnancy is an additional argument for single embryo transfer. TWEETABLE ABSTRACT: Assisted reproductive technology is associated with an increased risk of severe postpartum haemorrhage.

Evaluating the contribution of APOBEC3G haplotypes, on influencing HIV infection in a Zimbabwean paediatric population.

BACKGROUND: Apolipoprotein B mRNA-editing catalytic polypeptide like-3G (APOBEC3G) is an antiviral enzyme that reduces viral fitness by introducing uracil to thymidine hypermutations in viral genomes. Thus, polymorphisms in the APOBEC3G gene have been implicated in differential outcomes of HIV infection and disease progression. However, there is insufficient evidence on the role of APOBEC3G gene variants on HIV infection, especially in African populations. This study therefore describes polymorphisms in the APOBEC3G gene in a Zimbabwean paediatric population and evaluates their effects on susceptibility to HIV infection among children born to HIV-infected mothers. Methods. A total of 104 children aged between 7 and 9 years, comprising 68 perinatally exposed to HIV (32 born infected (EI) and 36 born uninfected (EU)) and 36 unexposed and uninfected (UEUI) controls were recruited. Allelic variants (n=5) in the APOBEC3G gene were characterised. Results. Frequencies for minor APOBEC3G alleles in the HIV-uninfected groups (EU and UEUI) were c.557G (40%), g.-90C (32%), g.-571C (12%), c.467-85C (42%), and c.582-162G (6%). APOBEC3G c.467-85C frequency was statistically significantly different when compared to the Masai of Kinyawa, Kenya population (42% v. 18%). None of the single nucleotide polymorphisms individually or as part of haplotypes were significantly associated with HIV infection when comparing the EI and EU groups. Conclusions. Our findings suggest that APOBEC3G polymorphisms alone may not have significant predictive power for inferring genetic susceptibility to vertical transmission of HIV in children perinatally exposed to HIV.

Uterine rupture: trends over 40 years.

OBJECTIVE: To follow trends of uterine rupture over a period of 40 years in Norway. DESIGN: Population-based study using data from the Medical Birth Registry, the Patient Administration System, and medical records. SETTING: Norway. SAMPLE: Women giving birth in 21 maternity units in Norway during the period 1967-2008 (n = 1 441 712 maternities). METHODS: The incidence and outcomes of uterine rupture were compared across four decades: 1967-1977; 1978-1988; 1989-1999; and 2000-2008. Multivariable logistic regression was used to determine the odds ratio (OR) for uterine rupture in each decade compared with the second decade. MAIN OUTCOME MEASURE: Trends in uterine rupture. RESULTS: We identified 359 uterine ruptures. The incidence rates per 10 000 maternities in the first, second, third, and fourth decade were 1.2, 0.9, 1.7, and 6.1, respectively. The ORs for complete and partial ruptures in the fourth versus the second decade were 6.4 (95% confidence interval, 95% CI 3.8-10.8) and 7.2 (95% CI 4.2-12.3), respectively. Significant contributing factors to this increase were the higher rates of labour augmentation with oxytocin, scarred uteri from a previous caesarean section, and labour induction with prostaglandins or prostaglandins combined with oxytocin. After adjusting for risk factors, the ORs for complete and partial ruptures were 2.2 (95% CI 1.3-3.8) and 2.8 (95% CI 1.6-4.8), respectively. Severe postpartum haemorrhage, hysterectomy, intrapartum death and infant death after complete uterine ruptures decreased significantly over time. CONCLUSIONS: A sharply increasing trend of uterine rupture was found. Obstetric interventions contributed to this increase, but could not explain it entirely. TWEETABLE ABSTRACT: A sharply increasing trend of uterine ruptures has been found in Norway in recent years.

Alcohol Consumption during Pregnancy and Postpartum Period and its Predictors in Sindhupalchowk District, Nepal.

BACKGROUND: A substantial proportion of women in Nepal consume alcohol and homebrewed alcoholic beverages are the most common type of alcohol. Alcohol being a part of tradition and culture in Nepal and evidences suggesting even low to moderate dose of alcohol having impacts on the birth outcomes, we aimed at exploring the alcohol consumption pattern during pregnancy and postpartum period along with its predictors. METHODS: We studied all pregnant and recently delivered women using quantitative methods in selected wards within selected Village Development Committees of Sindhupalchowk district in Nepal after purposively choosing the district. We present the findings on pregnancy and postpartum period drinking and its predictors as proportion and adjusted odds ratio along with 95% CI. RESULTS: One-third of women drank alcohol during pregnancy and 43% during postpartum period. Nearly all drinking women mostly consumed homebrewed alcoholic beverages such as jaad/chhyang/localraksi. One-third consumed it daily during pregnancy, while three-quarters consumed daily during postpartum. One-fifth of currently drinking women drank ≥5 standard drinks on average per day in the last 30 days. Illiterate or women with low level of education were three times more likely to consume alcohol during pregnancy than women with secondary level education or higher. Similarly, women who didn't know that alcohol during pregnancy affects mother and child were four and half times more likely to consume alcohol during pregnancy than those who knew about it. Also, being dalits, disadvantaged and janajatis, husband's drinking and home brewing of alcohol were strongly associated with women's drinking during pregnancy and postpartum period. CONCLUSIONS: A substantial proportion of women consumed alcohol during pregnancy and postpartum period with high consumption frequency. Findings suggested, increasing awareness about consequences of drinking during pregnancy and postpartum period would be helpful probably as one of the components of routine antenatal care with a special focus to ethnic groups such as dalits, disadvantaged janajatis including relatively advantaged janajatis as well as the women with lower levels of education. Culture sensitive behavior change communication interventions aimed at reducing home brewing and husband's drinking would also be important Keywords: Alcohol consumption; home brewed; Nepal; postpartum period; pregnancy; predictor.

Nepalese Homebrewed Alcoholic Beverages: Types, Ingredients, and Ethanol Concentration from a Nation Wide Survey.

BACKGROUND: Despite the enormous public health problems related to traditional alcohol consumption practice in Nepal, this area has been ignored and the information at the national level is limited. Thus this study is designed to explore the readily available commonly practiced Nepalese homebrewed alcoholic beverages, the ingredients used and alcohol strength (ethanol concentration). METHODS: This study was carried out as a part of ongoing household survey on "Alcohol consumption practice among married women of reproductive age in Nepal". A total of 284 homebrewed alcoholic beverage (distilled 175, non-distilled:109) samples were collected from the 16 survey districts of Nepal during the period of April to August, 2013. Ethanol percentage was tested in research lab by using standard procedure. RESULTS: Readily available homebrewed alcoholic beverages in practice were mainly of two types "Distilled" (local Raksi) and "Non-distilled" (Jand, Chhyang, Tumba). Rice, wheat, barley, millet, maize, fruits, and pure sugar were the commonly used ingredients to prepare alcohol. Ethanol concentration in homebrewed alcohol was 14.0% (IQR: 10.0-19.0) ranging from 3% to 40% for distilled, and 5.2% (IQR: 3.5-9.8) ranging from 1% to 18.9% for nondistilled. A significant difference (P<0.05) was found in alcohol strength by residence, development regions, types of alcohol, and the ingredients used. CONCLUSIONS: The median concentration of ethanol in readily available home brewed alcoholic beverages in Nepal was more than the strength of factory produced beer. The alcohol strength varies across their types, ingredients used, residence and regions.

A lower reduction in umbilical artery pulsatility in mid-pregnancy predicts higher infant blood pressure six months after birth.

AIM: The Norwegian-based Cardiovascular Risk Reduction Diet in Pregnancy study found that a cholesterol-lowering diet during pregnancy was associated with an accentuated reduction in the umbilical artery pulsatility index. This follow-up study assessed the possible association between the index and the infants' blood pressure at six months of age. METHODS: In the original study, pregnant women consumed an anti-atherogenic or usual diet from gestational weeks 17-20 to birth and underwent Doppler velocimetry at 24, 30 and 36 gestational weeks. In this follow-up study, blood pressure was measured in 105 mother-infant pairs in the intervention group and 106 mother-infant pairs in the control group six months after birth. RESULTS: Mean systolic and diastolic blood pressures were not significantly different between both groups. When the groups were combined, multivariate linear analyses showed that a lower versus higher reduction (≥-0.17 versus <-0.17) in the umbilical artery pulsatility index between gestational weeks 24 and 30 and maternal diastolic blood pressure at six months postpartum were significant predictors of higher infant systolic blood pressure (p = 0.03, 0.01, respectively). CONCLUSION: A lower reduction in umbilical pulsatility index in mid-pregnancy was associated with higher infant blood pressure at six months of age. This suggests that fetoplacental intrauterine factors may influence future cardiovascular risk.

Intrapartum GBS screening and antibiotic prophylaxis: a European consensus conference.

Group B streptococcus (GBS) remains worldwide a leading cause of severe neonatal disease. Since the end of the 1990s, various strategies for prevention of the early onset neonatal disease have been implemented and have evolved. When a universal antenatal GBS screening-based strategy is used to identify women who are given an intrapartum antimicrobial prophylaxis, a substantial reduction of incidence up to 80% has been reported in the USA as in other countries including European countries. However recommendations are still a matter of debate due to challenges and controversies on how best to identify candidates for prophylaxis and to drawbacks of intrapartum administration of antibiotics. In Europe, some countries recommend either antenatal GBS screening or risk-based strategies, or any combination, and others do not have national or any other kind of guidelines for prevention of GBS perinatal disease. Furthermore, accurate population-based data of incidence of GBS neonatal disease are not available in some countries and hamper good effectiveness evaluation of prevention strategies. To facilitate a consensus towards European guidelines for the management of pregnant women in labor and during pregnancy for the prevention of GBS perinatal disease, a conference was organized in 2013 with a group of experts in neonatology, gynecology-obstetrics and clinical microbiology coming from European representative countries. The group reviewed available data, identified areas where results were suboptimal, where revised procedures and new technologies could improve current practices for prevention of perinatal GBS disease. The key decision issued after the conference is to recommend intrapartum antimicrobial prophylaxis based on a universal intrapartum GBS screening strategy using a rapid real time testing.

The burden and predictors of cognitive impairment among 6- to 8-year-old children infected and uninfected with HIV from Harare, Zimbabwe: a cross-sectional study.

With long-term survival of children infected with HIV, information on cognitive function at school age is needed. To determine cognitive function among 6- to 8 year-old children exposed to HIV and to assess factors associated with cognitive impairment, we conducted a cross-sectional study from October 2010 to December 2011 among children whose mothers participated in a national HIV prevention program in Harare. Cognitive function was assessed using the McCarthy Scales of Children's Abilities (MSCA). Of the 306 assessed children, 32 (10%) were HIV infected, 121 (40%) exposed uninfected, and 153 (50%) unexposed uninfected. The mean (SD) General Cognitive Index for the whole study group was 82 (15). An overall of 49 (16%) out of the 306 children had cognitive impairment with no difference in general cognitive function among the three groups. Children with HIV infection scored lowest in perceptual performance domain, p = .028. Unemployed caregivers, child orphanhood and undernutrition were associated with impaired cognitive performance in univariate analysis. In multivariate analysis, caregiver unemployment status remained a factor associated with cognitive impairment with an ODDS ratio of 2.1 (95% CI 1.03-3.36). In a cohort of 6- to 8-year-olds, HIV infection did not show evidence of significant difference in general cognitive function. Children infected with HIV had major deficits in perceptive performance. Lower socioeconomic status was associated with cognitive impairment. In resource-constrained settings, strategies aimed at poverty alleviation and good nutritional management should complement early infant diagnosis and treatment of HIV in order to optimize neurocognitive potential.

Anaemia and iron deficiency in peri-urban school children born in a National HIV Prevention Programme in Zimbabwe: A cross-sectional study.

OBJECTIVE: To determine the prevalence of anaemia, iron deficiency and iron deficiency anaemia in school children who were born in a national HIV prevention programme. DESIGN: This was a community based cross-sectional study. SETTING: A resource poor peri-urban setting with high prevalence of HIV infection. SUBJECTS: School aged children six to 10 years old who were born in a national mother-to-child HIV prevention programme. MAIN OUTCOME MEASURES: Haemoglobin (Hb), serum Ferritin (F) and serum Transferrin receptor (sTfR) levels. RESULTS: Three hundred and eighteen children were recruited including 21 HIV positive. The prevalence of anaemia (Hb < 11.5 grams per litre), iron deficiency (F<15 micrograms per litre) and iron deficiency anaemia (Hb < 11.5 g/L and either F < 15 µg/L or sTfR > 8.3 µg/L) were 15%, 4% and 2% respectively. When a higher cut-off for ferritin of 30 micrograms per litre was applied to adjust for high infection disease burden, iron deficiency prevalence increased to 32% and iron deficiency anaemia increased to 5%. Anaemia was 4.9 (C.I 1.9-12.4) times more likely to occur in HIV infected children compared to the HIV uninfected children. Maternal HIV status at birth was not related to presence of anaemia in the school children. CONCLUSION: Anaemia was of mild public health significance in this cohort of children. Iron deficiency anaemia contributed less than a quarter of the cases of anaemia. HIV infection was an important determinant for presence of anaemia. Therefore continued efforts to eliminate paediatric HIV infection as a way of reducing anaemia in children are essential.

HLA-DRB1, -DQA1 and -DQB1 alleles and haplotypes in first-generation Pakistani immigrants in Norway.

Human leucocyte antigen (HLA) polymorphisms among immigrants from Pakistan have not been well investigated. Immigration to Norway started in the late 1960s for working purposes. From 1975, immigration was mainly for marriages and family reunion. When recruiting couples for a birth cohort study, we ended up with 65.5% of the 374 parents genotyped being closely related. This was also reflected in that 21% of newborns were homozygotes for their DRB1-DQA1-DQB1 genotype. For being able to study HLA class II genes frequencies among unrelated individuals, we had to exclude 195 of the parents from data analysis. High-resolution typing for the DRB1 locus, low/intermediate for the DQA1 locus and resolution genotyping for the DQB1 locus were performed in all the 179 parents and their newborns from the Punjab province of Pakistan. We identified 25 DRB1, nine DQA1 and 14 DRB1 alleles in the 179 unrelated parents included in our analysis. The most frequent alleles were DRB1*03:01:01 (15.9%) and DRB1*07:01:01 (15.9%), DQA1*01:03 (22.1%) and DQB1*02:01:01 (26.0%). Forty-one haplotypes were identified, including DRB1*13:02:01-DQA1*01:02-DQB1*06:03:01, not earlier reported. Supported by the few earlier reports on Pakistani groups living in Pakistan, it appears that alleles found among those living in Norway are of Indo-European or mixed ethnic origin. This study provides the first comprehensive report of HLA class II alleles and haplotypes in Norwegian Pakistani immigrants. When the unrelated parents were compared with all parents genotyped, there were, however, no significant differences in allele frequencies, confirming that consanguineous marriages are usual in Pakistan.

Realities and Challenges of a Five Year Follow Up of Mother and Child Pairs on a PMTCT Program in Zimbabwe.

BACKGROUND: Complete follow up is an essential component of observational cohorts irrespective of the type of disease. OBJECTIVES: To describe five years follow up of mother and child pairs on a PMTCT program, highlighting loss to follow up (LTFU) and mortality (attrition). STUDY DESIGN: A cohort of pregnant women was enrolled from the national PMTCT program at 36 weeks gestational age attending three peri urban clinics around Harare offering maternal and child health services. Mother-infant pairs were followed up from birth and twice yearly for five years. RESULTS: A total of 479 HIV infected and 571 HIV negative pregnant women were enrolled, 445(92.9%) and 495(86.6%) were followed up whereas 14(3.0%) and 3(0.5%) died in the 1st year respectively; RR (95%CI) 5.3(1.5-18.7). At five years 227(56.7%) HIV infected and 239(41.0%) HIV negative mothers turned up, whereas mortality rates were 34 and 7 per 100 person years respectively. Birth information was recorded for 401(83.7%) HIV exposed and 441(77.2%) unexposed infants, 247(51.6%) and 232(40.6) turned up in the first year whilst mortality was 58(12.9%) and 22(4.4%) respectively, RR (95%CI) 3.2(2.0-5.4). At five years 210(57.5%) HIV exposed and 239(44.3%) unexposed infants were seen, whilst mortality rates were 53 per 1000 and 15 per 1 000 person years respectively. Mortality rate for HIV infected children was 112 compared to 21 per 1 000 person years for the exposed but uninfected. CONCLUSION: HIV infected mothers and their children succumbed to mortality whereas the HIV negatives were LTFU. Mortality rates and LTFU are high within PMTCT program.

Analysis of 'count-to-ten' fetal movement charts: a prospective cohort study.

OBJECTIVE: We aimed to describe patterns of maternally perceived fetal movement (FM) counts in normal third-trimester pregnancies and present associations between published limits of decreased fetal movement (DFM) and FM patterns in the total population. DESIGN: Prospective cohort study. SETTING: Norway, in 2005-2007 and 2007-2009. POPULATION: The total population of women with singleton pregnancies. METHODS: Using a 'count-to-ten' approach, women counted FMs daily from pregnancy week 28 until delivery. Data on maternal characteristics and birth outcomes were obtained from the Medical Birth Registry of Norway and hospital records. We measured the observed mean counting time and used chi-square and Mann-Whitney U-tests to examine differences between normal pregnancies and pregnancies with suboptimal outcomes. MAIN OUTCOME MEASURES: Fetal movements in normal pregnancies and in pregnancies ending in a small-for-gestational-age baby, preterm birth or non-elective caesarean section. RESULTS: A total of 1786 women were included. The mean time to perceive ten movements was approximately 10 minutes in normal pregnancies, with a <2-minute increase in the mean towards term. Fixed limits for DFMs had low predictive values. Overall, the mean counting time in pregnancies with suboptimal outcomes did not differ markedly from normal pregnancies. CONCLUSIONS: This study does not support the notion that FM counts decrease at term in normal pregnancies. A standard approach to FM counting, applying the currently best-founded definition of DFM, was not useful as a screening tool for at-risk pregnancies in this population. Further research is needed to improve measurements of DFM.

A new tool for the validation of umbilical cord acid-base data.

OBJECTIVE: To identify the distribution of carbon dioxide tension (pCO(2) ) relative to pH in validated umbilical cord acid-base data. DESIGN: Observational study. SETTING: European hospital labour wards. POPULATION: Data for 36,432 term newborns were obtained from three sources: two trials of fetal monitoring with electrocardiography (ECG; the Swedish randomised controlled trial and the European Union Fetal ECG trial) and data from Mölndal Hospital. METHODS: From the total study population, cases with missing values or obvious typing errors were excluded. The remaining data were validated based on specified criteria. Percentiles of arterial pCO(2) by pH were calculated using multilevel regression modelling. MAIN OUTCOME MEASURES: Umbilical cord pH, pCO(2) and base deficit. RESULTS: Acid-base values were considered invalid in one out of seven cases. Percentiles for arterial pCO(2) corresponding to specified values of arterial pH were developed from the validated data of 26, 690 cases. CONCLUSIONS: Percentiles for arterial pCO(2) for a specified arterial pH can be used as a tool to identify cases with erroneously low pCO(2) values, and thus avoid an incorrect interpretation of the newborn's acid-base status.

Uterine rupture after previous caesarean section.

OBJECTIVE: To determine the risk factors, percentage and maternal and perinatal complications of uterine rupture after previous caesarean section. DESIGN: Population-based registry study. POPULATION: Mothers with births > or =28 weeks of gestation after previous caesarean section (n = 18 794), registered in the Medical Birth Registry of Norway, from 1 January 1999 to 30 June 2005. METHODS: Associations of uterine rupture with risk factors, maternal and perinatal outcome were estimated using cross-tabulations and logistic regression. MAIN OUTCOME MEASURE: Odds of uterine rupture. RESULTS: A total of 94 uterine ruptures were identified (5.0/1000 mothers). Compared with elective prelabour caesarean section, odds of rupture increased for emergency prelabour caesarean section (OR: 8.63; 95% CI: 2.6-28.0), spontaneous labour (OR: 6.65; 95% CI: 2.4-18.6) and induced labour (OR: 12.60; 95% CI: 4.4-36.4). The odds were increased for maternal age > or =40 years versus <30 years (OR: 2.48; 95% CI: 1.1-5.5), non-Western (mothers born outside Europe, North America or Australia) origin (OR: 2.87; 95% CI: 1.8-4.7) and gestational age > or =41 weeks versus 37-40 weeks (OR: 1.73; 95% CI: 1.1-2.7). Uterine rupture after trial of labour significantly increased severe postpartum haemorrhage (OR: 8.51; 95% CI: 4.6-15.1), general anaesthesia exposure (OR: 14.20; 95% CI: 9.1-22.2), hysterectomy (OR: 51.36; 95% CI: 13.6-193.4) and serious perinatal outcome (OR: 24.51 (95% CI: 11.9-51.9). Induction by prostaglandins significantly increased the odds for uterine rupture compared with spontaneous labour (OR: 2.72; 95% CI: 1.6-4.7). Prelabour ruptures occurred after latent uterine activity or abdominal pain in mothers with multiple or uncommon uterine scars. CONCLUSION: Trial of labour carried greater risk and graver outcome of uterine rupture than elective repeated caesarean section, although absolute risks were low. A review of labour management and induction protocol is needed.

Risk factors of HIV vertical transmission in a cohort of women under a PMTCT program at three peri-urban clinics in a resource-poor setting.

OBJECTIVE: To identify the risk factors of HIV vertical transmission in pregnant women. STUDY DESIGN: Observational cohort study. Between 2002 and 2003, 479 HIV-infected pregnant women in a PMTCT (prevention of the mother-to-child transmission) program were followed up with their infants at delivery, until 15 months with infant HIV testing. RESULTS: Of these 281 infants had a definitive HIV result by 15 months of age, and 31.7% of the infants become HIV infected. In univariate analysis the risk factor identified were presence of vaginal discharge, genital itchiness, genital ulcers, dysuria, abnormal breast and vaginal infections (Trichomonas, Bacteria vaginosis and Candida) in the mother at enrolment. In multivariate analysis vaginal infections risk ratio (RR) 1.72(1.03-2.88) and abnormal breast RR 4.36(2.89-6.58) were predictors of HIV vertical transmission. CONCLUSION: There is need to screen for vaginal infections (Trichomonas, Bacteria vaginosis and Candida) and examine pregnant women for mastitis to identify women at risk of HIV vertical transmission for prevention.

Effect of maternal HIV status on infant mortality: evidence from a 9-month follow-up of mothers and their infants in Zimbabwe.

OBJECTIVE: To describe infant mortality trends and associated factors among infants born to mothers enrolled in a prevention of mother-to-child transmission (PMTCT) program. STUDY DESIGN: A nested case-control study of human immunodeficiency virus (HIV)-positive and -negative pregnant women enrolled from the national PMTCT program at 36 weeks of gestation attending three peri-urban clinics in Zimbabwe offering maternal and child health care. Mother-infant pairs were followed up from delivery, and at 6 weeks, 4 months and 9 months. RESULTS: A total of 1045 mother and singleton infant pairs, 474 HIV-positive and 571 HIV-negative mothers, delivered 469 and 569 live infants, respectively. Differences in mortality were at 6 weeks and 4 months, RR (95% CI) 9.71 (1.22 to 77.32) and 21.84 (2.93 to 162.98), respectively. Overall, 9-month mortality rates were 150 and 47 per 1000 person-years for infants born to HIV-positive and HIV-negative mothers, respectively. Proportional hazard ratio of mortality for children born to HIV-positive mothers was 3.21 (1.91 to 5.38) when compared with that for children born to HIV-negative mothers. CONCLUSION: Maternal HIV exposure was associated with higher mortality in the first 4 months of life. Infant's HIV status was the strongest predictor of infant mortality. There is a need to screen infants for HIV from delivery and throughout breastfeeding.
