RESUMO
BACKGROUND: Cervical cancer is the second cause of cancer deaths among Ethiopian women. Despite multifaceted government efforts, the uptake and utilization of cervical cancer screening remain very low. This study aimed to assess factors influencing the uptake and utilization of cervical cancer screening at public health centers in Addis Ababa. METHODS: A convergent parallel mixed-method study was employed to collect data through eight focus group discussions with 66 women purposively recruited from outpatient clinics, and cross-sectional face-to-face exit interviews with 80 women attending cervical cancer clinics in four high-patient volume health centers. The group interviews were tape-recorded, transcribed in Amharic, translated into English, and a thematic analysis approach was used in the analysis. Exit interview data were collected using a structured questionnaire in the Open Data Kit tool on an android tablet. STATA version 17 was used for descriptive and inferential data analyses. Statistical significance was set at p < 0.05. RESULTS: The majority of focus group discussion participants had lack of knowledge of cervical cancer and its screening services. The major barriers to the uptake of screening were inadequate public awareness, fear of the procedure, embarrassment, provider's gender, lack of male partner support, and childcare. Women aged 40 years and above were 13.9 times more likely to utilize cervical cancer screening than those under 30 years (AOR = 13.85; 95% CI: 1.40, 136.74). There was a strong preference for a female provider (AOR = 7.07; 95% CI: 1.53, 32.75) among women screened after attending antiretroviral therapy clinics and those screened due to abnormal vaginal bleeding than women referred from family planning clinics (AOR = 6.87; 95% CI: 1.02, 46.44). Safety of screening was negatively associated with women aged 30-39 (AOR = 0.045; 95% CI: 0.003, 0.696), and those who attended primary education, and secondary education and above, (AOR = 0.016; 95% CI: 0.001, 0.262), and (AOR = 0.054; 95% CI: 0.004, 0.724), respectively. CONCLUSIONS: The study identified low public awareness, inadequate provider preference, safety concerns, and poor male partner support for cervical cancer screening. We recommend the decision-makers enhance public messages, maintain provider choices, ensure safety, and engage males to improve the uptake and utilization of cervical cancer screening.

BACKGROUND: Maternal mortality is still unacceptably high in Kenya. The Kenyan Government introduced a free maternity service to overcome financial barriers to access. This policy led to a substantial increase in women's delivery options. This increase in coverage might have led to a reduction in quality of care. This study explores women's perceptions of quality of delivery services in the context of the free policy and how the perceptions lead to the choice of a place for delivery. METHODS: Our study site was Naivasha sub-County in Kenya, a rural context, whose geography encompasses pastoralists, rural agrarian, and high population density informal settlements near flower farms. Women from this area are from the lowest wealth quintile in Kenya. We conducted a qualitative study to explore the women's perceptions of quality of care based on their experiences during maternity care. The participants were women of reproductive age (18-49 years) attending antenatal care clinics at six health facilities in the sub-county. Six focus group discussions with 55 respondents were used. For inclusion, the women needed to have delivered a baby within the six months preceding the study. Interviews were recorded with consent, translated and transcribed. The interviews were analyzed using a thematic content approach. RESULTS: Four broad themes that determined the choice of health facility for delivery were identified: women's perceptions of clinical quality of care; the cost of delivery; distance to the health facility and management of primary health facilities. An unexpected theme was the presence of home deliveries amongst pastoralist women. These findings suggest that in this setting both process and structural dimensions of quality of care and financial and physical accessibility influence women's choices for place of delivery. CONCLUSION: This study expands our understanding of how women make choices regarding place of delivery. Understanding women's perceptions can provide useful insights to policy makers and facility managers on providing high quality patient centered maternity care necessary to sustain the increased utilization of maternity services at health facilities under the free maternity policy and further reductions in maternal mortality.

BACKGROUND: HIV-1 is highly variable genetically and at protein level, a property it uses to subvert antiviral immunity and treatment. The aim of this study was to assess if HIV subtype differences were associated with variations in glycosylation patterns and co-receptor tropism among HAART patients experiencing different virologic treatment outcomes. METHODS: A total of 118 HIV env C2V3 sequence isolates generated previously from 59 Kenyan patients receiving highly active antiretroviral therapy (HAART) were examined for tropism and glycosylation patterns. For analysis of Potential N-linked glycosylation sites (PNGs), amino acid sequences generated by the NCBI's Translate tool were applied to the HIVAlign and the N-glycosite tool within the Los Alamos Database. Viral tropism was assessed using Geno2Pheno (G2P), WebPSSM and Phenoseq platforms as well as using Raymond's and Esbjörnsson's rules. Chi square test was used to determine independent variables association and ANOVA applied on scale variables. RESULTS: At respective False Positive Rate (FPR) cut-offs of 5% (p = 0.045), 10% (p = 0.016) and 20% (p = 0.005) for CXCR4 usage within the Geno2Pheno platform, HIV-1 subtype and viral tropism were significantly associated in a chi square test. Raymond's rule (p = 0.024) and WebPSSM (p = 0.05), but not Phenoseq or Esbjörnsson showed significant associations between subtype and tropism. Relative to other platforms used, Raymond's and Esbjörnsson's rules showed higher proportions of X4 variants, while WebPSSM resulted in lower proportions of X4 variants across subtypes. The mean glycosylation density differed significantly between subtypes at positions, N277 (p = 0.034), N296 (p = 0.036), N302 (p = 0.034) and N366 (p = 0.004), with HIV-1D most heavily glycosylated of the subtypes. R5 isolates had fewer PNGs than X4 isolates, but these differences were not significant except at position N262 (p = 0.040). Cell-associated isolates from virologic treatment success subjects were more glycosylated than cell-free isolates from virologic treatment failures both for the NXT (p = 0.016), and for all the patterns (p = 0.011). CONCLUSION: These data reveal significant associations of HIV-1 subtype diversity, viral co-receptor tropism, viral suppression and envelope glycosylation. These associations have important implications for designing therapy and vaccines against HIV. Heavy glycosylation and preference for CXCR4 usage of HIV-1D may explain rapid disease progression in patients infected with these strains.

Clinical signs and symptoms of cerebral malaria in children are nonspecific and are seen in other common encephalopathies in malaria-endemic areas. This makes accurate diagnosis difficult in resource-poor settings. Novel malaria-specific diagnostic and prognostic methods are needed. We have used 2 proteomic strategies to identify differentially expressed proteins in plasma and cerebrospinal fluid from children with a diagnosis of cerebral malaria, compared with those with a diagnosis of malaria-slide-negative acute bacterial meningitis and other nonspecific encephalopathies. Here we report the presence of differentially expressed proteins in cerebral malaria in both plasma and cerebrospinal fluid that could be used to better understand pathogenesis and help develop more-specific diagnostic methods. In particular, we report the expression of 2 spectrin proteins that have known Plasmodium falciparum-binding partners involved in the stability of the infected red blood cell, suppressing further invasion and possibly enhancing the red blood cell's ability to sequester in microvasculature.

Following an upsurge in cervical cancer incidence and mortality, Ethiopia developed its first National Cancer Control Plan (NCCP) to support efforts toward the prevention and control of cancer. The NCCP outlines strategies for reducing the incidence of cancer through prevention, screening, early diagnosis, treatment, and palliative care. This study examined barriers and facilitators to the implementation of the NCCP using a qualitative approach. The study entailed doing key informant interviews and reviewing secondary data. Using customized topic guidelines, fifteen interviews were conducted covering a wide range of topics, including political commitment, priority setting, interagency cooperation, the role of evidence, citizen empowerment, and incentives. All interviews were recorded (with consent), transcribed in Amharic, and then translated into English for thematic analysis. Review of secondary data focused on establishing the NCCP's implementation status for HPV vaccination, cervical cancer screening, and treatment, and strategic links to five other national policy documents centered on public awareness, cervical cancer services, HPV immunization, and sexually transmitted infections control. We found that in 2022, 55% of eligible Ethiopian women were screened for cervical cancer (against the annual target), with roughly half of those with a positive result receiving treatment. Overall, 900,000 (8.4%) of the 10.7 million eligible women in the country underwent screening. The study revealed inadequate implementation of the NCCP strategies toward achieving the WHO's 90-70-90 cervical cancer targets by 2030. A key positive strategy was the involvement of high-ranking government officials in the National Cancer Committee, which aided the NCCP implementation. On the other hand, inadequate political support, funding constraints, suboptimal public messaging, lack of incentives, and inadequate partnership arrangements emerged as important barriers. We recommend that decision-makers intensify coordinated efforts, prioritize dealing with identified challenges and optimizing facilitators, and mobilize additional resources to enhance cervical cancer services in Ethiopia.
RESUMO
This study examines the impact of the COVID-19 pandemic on the availability of essential medicines in Kenya and suggests actionable measures to enhance the country's preparedness for future pandemics. Utilising a cross-sectional qualitative design, the research combines a systematic review of the literature and 20 key informant interviews to provide a comprehensive analysis. The initial response to the pandemic involved resource reallocation, disrupting the procurement of essential medicines at national and county levels. Inefficiencies in these systems resulted in shortages and wastages of crucial medicines, exposing vulnerabilities in the health system. Furthermore, the study reveals regulatory policy weaknesses in Kenya, such as an inadequate legal framework for domestic pharmaceutical manufacturing and conflicting policies hindering medicine availability. The study recommends a multifaceted policy approach to ensure essential medicine availability during crises. Key recommendations include strengthening financial systems through increased government investments and innovative funding mechanisms, implementing price regulation policies, and enhancing the resilience of supply chain and procurement systems. Collaboration among various supply systems is essential to prevent stock-outs. Strengthening legislation and regulatory policies, increasing domestic pharmaceutical manufacturing capacity, and investing in health information systems are vital for sustained self-sufficiency and efficient service delivery. These comprehensive measures are essential to promote essential medicine availability, safeguard public health, and enhance resilience during crises.
RESUMO
BACKGROUND: Cervical cancer is the second leading cause of cancer death among Ethiopian women. This study aimed to assess the influence of the health system on access to cervical cancer prevention, screening, and treatment services at public health centers in Addis Ababa, Ethiopia. METHODS: This study used a cross-sectional survey design and collected data from 51 randomly selected public health centers in Addis Ababa. Open Data Kit was used to administer a semi-structured questionnaire on Android tablets, and SPSS version 26 was used to analyze the descriptive data. RESULTS: In the study conducted at 51 health centers, cervical cancer prevention and control services achieved 61% HPV vaccination for girls, 79% for cervical cancer awareness messages, 80% for precancer lesion treatment, and 71% for cervical screening of women. All health centers were performing cervical screening mostly through visual inspection with acetic acid due to the inconsistent availability of HPV DNA tests and the lack of Pap smear tests. In 94% of health centers, adequate human resources were available. However, only 78% of nurses, 75% of midwives, 35% of health officers, and 49% of health extension workers received cervical cancer training in the 24 months preceding the study. Women had provider choices in only 65% of health centers, and 86% of the centers lacked electronic health records. In 41% of the health centers, the waiting time was 30 minutes or longer. About 88% and 90% of the facilities lacked audio and video cervical cancer messages, respectively. CONCLUSION: This study revealed that the annual cervical cancer screening achievement was on track to fulfill the WHO's 90-70-90 targets by 2030. We recommend that decision-makers prioritize increasing HPV vaccination rates, enhancing messaging, reducing wait times, and implementing electronic health records to improve access to cervical cancer services in Addis Ababa.

The coronavirus pandemic (COVID-19) has triggered a public health and economic crisis in high and low resource settings since the beginning of 2020. With the first case being discovered on 12th March 2020, Kenya has responded by using health and non-health strategies to mitigate the direct and indirect impact of the disease on its population. However, this has had positive and negative implications for the country's overall health system. This paper aimed to understand the pandemic's impact and develop lessons for future response by identifying the key challenges and opportunities Kenya faced during the pandemic. We conducted a qualitative study with 15 key informants, purposefully sampled for in-depth interviews from September 2020 to February 2021. We conducted direct content analysis of the transcripts to understand the stakeholder's views and perceptions of how COVID-19 has affected the Kenyan healthcare system. Most of the respondents noted that Kenya's initial response was relatively good, especially in controlling the pandemic with the resources it had at the time. This included relaying information to citizens, creating technical working groups and fostering multisectoral collaboration. However, concerns were raised regarding service disruption and impact on reproductive health, HIV, TB, and non-communicable diseases services; poor coordination between the national and county governments; shortage of personal protective equipment and testing kits; and strain of human resources for health. Effective pandemic preparedness for future response calls for improved investments across the health system building blocks, including; human resources for health, financing, infrastructure, information, leadership, service delivery and medical products and technologies. These strategies will help build resilient health systems and improve self-reliance, especially for countries transitioning from donor aid such as Kenya in the event of a pandemic.
RESUMO
BACKGROUND: Severe malnutrition is frequently complicated by sepsis, leading to high case fatality. Oral ciprofloxacin is a potential alternative to the standard parenteral ampicillin/gentamicin combination, but its pharmacokinetics in malnourished children is unknown. METHODS: Ciprofloxacin (10 mg/kg, 12 hourly) was administered either 2 h before or up to 2 h after feeds to Kenyan children hospitalized with severe malnutrition. Four plasma ciprofloxacin concentrations were measured over 24 h. Population analysis with NONMEM investigated factors affecting the oral clearance (CL) and the oral volume of distribution (V). Monte Carlo simulations investigated dosage regimens to achieve a target AUC(0-24)/MIC ratio of ≥125. RESULTS: Data comprised 202 ciprofloxacin concentration measurements from 52 children aged 8-102 months. Absorption was generally rapid but variable; C(max) ranged from 0.6 to 4.5 mg/L. Data were fitted by a one-compartment model with first-order absorption and lag. The parameters were CL (L/h)â=â42.7 (L/h/70 kg)â×â[weight (kg)/70](0.75)â×â[1â+â0.0368 (Na(+) - 136)]â×â[1â-â0.283 (high risk)] and V (L)â=â372â×â(L/70 kg)â×â[1â+â0.0291 (Na(+) - 136)]. Estimates of AUC(0-24) ranged from 8 to 61 mg·h/L. The breakpoint for Gram-negative organisms was <0.06 mg/L with doses of 20 mg/kg/day and <0.125 mg/L with doses of 30 or 45 mg/kg/day. The cumulative fraction of response with 30 mg/kg/day was ≥80% for Escherichia coli, Klebsiella pneumoniae and Salmonella species, but <60% for Pseudomonas aeruginosa. CONCLUSIONS: An oral ciprofloxacin dose of 10 mg/kg three times daily (30 mg/kg/day) may be a suitable alternative antibiotic for the management of sepsis in severely malnourished children. Absorption was unaffected by the simultaneous administration of feeds.

BACKGROUND: A global proteomic strategy was used to identify proteins, which are differentially expressed in the murine model of severe malaria in the hope of facilitating future development of novel diagnostic, disease monitoring and treatment strategies. METHODS: Mice (4-week-old CD1 male mice) were infected with Plasmodium berghei ANKA strain, and infection allowed to establish until a parasitaemia of 30% was attained. Total plasma and albumin depleted plasma samples from infected and control (non-infected) mice were separated by two-dimensional gel electrophoresis (2-DE). After staining, the gels were imaged and differential protein expression patterns were interrogated using image analysis software. Spots of interest were then digested using trypsin and the proteins identified using matrix-assisted laser desorption and ionization-time of flight (MALDI-TOF) mass spectrometry (MS) and peptide mass fingerprinting software. RESULTS: Master gels of control and infected mice, and the corresponding albumin depleted fractions exhibited distinctly different 2D patterns comparing control and infected plasma, respectively. A wide range of proteins demonstrated altered expression including; acute inflammatory proteins, transporters, binding proteins, protease inhibitors, enzymes, cytokines, hormones, and channel/receptor-derived proteins. CONCLUSIONS: Malaria-infection in mice results in a wide perturbation of the host serum proteome involving a range of proteins and functions. Of particular interest is the increased secretion of anti-inflammatory and anti apoptotic proteins.

BACKGROUND: Previous investigations indicate that methotrexate, an old anticancer drug, could be used at low doses to treat malaria. A phase I evaluation was conducted to assess the safety and pharmacokinetic profile of this drug in healthy adult male Kenyan volunteers. METHODS: Twenty five healthy adult volunteers were recruited and admitted to receive a 5 mg dose of methotrexate/day/5 days. Pharmacokinetics blood sampling was carried out at 2, 4, 6, 12 and 24 hours following each dose. Nausea, vomiting, oral ulcers and other adverse events were solicited during follow up of 42 days. RESULTS: The mean age of participants was 23.9 ± 3.3 years. Adherence to protocol was 100%. No grade 3 solicited adverse events were observed. However, one case of transiently elevated liver enzymes, and one serious adverse event (not related to the product) were reported. The maximum concentration (C(max)) was 160-200 nM and after 6 hours, the effective concentration (C(eff)) was <150 nM. CONCLUSION: Low-dose methotraxate had an acceptable safety profile. However, methotrexate blood levels did not reach the desirable C(eff) of 250-400-nM required to clear malaria infection in vivo. Further dose finding and safety studies are necessary to confirm suitability of this drug as an anti-malarial agent.

OBJECTIVES: To investigate the health managers perceived sustainability status of the health facilities institutional improvement projects and their experiences on factors that facilitated or constrained their maintenance, with intentions of informing relevant strategies or policies in Kenya's health sector. METHODS: A qualitative study, nested within a quasi-experimental study. Thirty-three project-teams of health managers were purposively selected and interviewed based on their project implementation success rates post-training. The managers had previously undergone a 9-month leadership training, complimented with facility-based team coaching around the chosen projects. The training was funded by the US Agency for International Development; however, the implementation of the projects was based on how the participants could innovatively use the existing resource to create a positive change. The projects were housed within 20 public, 9 faith-based and 4 private health facilities in 19 counties in Kenya. The interviews explored the manager's experiences in sustaining the successfully implemented projects within the (24-60 months post-training period). We asked managers to describe factors they perceived enabled or hindered the sustainability of the successfully implemented institutional improvement project. The digitally audio-recorded interviews were transcribed verbatim. Data on barriers and enablers were thematically analysed. RESULTS: Twenty-nine out of the 33 successfully implemented projects reported sustainability within periods ranging from 24 to 60 months post-training. Seven themes related to drivers of sustainability emerged, namely; programme design, stakeholder's buy-in, board members, communication, coaching, presence of change champion, devolution and political good-will. Four sustainability inhibitors identified were: human resources constraints, policy implementation, misalignment of projects with daily operations, devolution and political interference. CONCLUSIONS: The sustainability of institutional improvement strategies such as projects implemented post-leadership training in public and private health facilities depends on the quality of board members, communication management and institutionalisation of coaching culture. These findings are pertinent for planning and implementing similar health systems strengthening intervention in low-income countries.

INTRODUCTION: Intramuscular paromomycin monotherapy to treat visceral leishmaniasis (VL) has been shown to be effective for Indian patients, while a similar regimen resulted in lower efficacy in Eastern Africa, which could be related to differences in paromomycin pharmacokinetics. METHODS: Pharmacokinetic data were available from two randomized controlled trials in VL patients from Eastern Africa and India. African patients received intramuscular paromomycin monotherapy (20 mg/kg for 21 days) or combination therapy (15 mg/kg for 17 days) with sodium stibogluconate. Indian patients received paromomycin monotherapy (15 mg/kg for 21 days). A population pharmacokinetic model was developed for paromomycin in Eastern African and Indian VL patients. RESULTS: Seventy-four African patients (388 observations) and 528 Indian patients (1321 observations) were included in this pharmacokinetic analysis. A one-compartment model with first-order kinetics of absorption and elimination best described paromomycin in plasma. Bioavailability (relative standard error) was 1.17 (5.18%) times higher in Kenyan and Sudanese patients, and 2.46 (24.5%) times higher in Ethiopian patients, compared with Indian patients. Ethiopian patients had an approximately fourfold slower absorption rate constant of 0.446 h-1 (18.2%). Area under the plasma concentration-time curve for 24 h at steady-state (AUCτ,SS) for 15 mg/kg/day (median [interquartile range]) was higher in Kenya and Sudan (172.7 µg·h/mL [145.9-214.3]) and Ethiopia (230.1 µg·h/mL [146.3-591.2]) compared with India (97.26 µg·h/mL [80.83-123.4]). CONCLUSION: The developed model provides detailed insight into the pharmacokinetic differences among Eastern African countries and India, however the resulting differences in paromomycin exposure do not seem to explain the geographical differences in paromomycin efficacy in the treatment of VL patients.

PURPOSE: Epilepsy is common in sub-Saharan Africa but is poorly characterized. Most studies are hospital-based, and may not reflect the situation in rural areas with limited access to medical care. We examined people with active convulsive epilepsy (ACE), to determine if the clinical features could help elucidate the causes. METHODS: We conducted a detailed descriptive analysis of 445 people with ACE identified through a community-based survey of 151,408 people in rural Kenya, including the examination of electroencephalograms. RESULTS: Approximately half of the 445 people with ACE were children aged 6 to 18 years. Seizures began in childhood in 78% of those diagnosed. An episode of status epilepticus was recalled by 36% cases, with an episode of status epilepticus precipitated by fever in 26%. Overall 169 had an abnormal electroencephalogram, 29% had focal features, and 34% had epileptiform activity. In the 146 individuals who reported generalized tonic-clonic seizures only, 22% had focal features on their electroencephalogram. Overall 71% of patients with ACE had evidence of focal abnormality, documented by partial onset seizures, focal neurologic deficits, or focal abnormalities on the electroencephalogram. Increased seizure frequency was strongly associated with age and cognitive impairment in all ages and nonattendance at school in children (p < 0.01). DISCUSSION: Children and adolescents bear the brunt of epilepsy in a rural population in Africa. The predominance of focal features and the high proportion of patients with status epilepticus, suggests that much of the epilepsy in this region has identifiable causes, many of which could be prevented.

BACKGROUND: Pentoxifylline (PTX) affects many processes that may contribute to the pathogenesis of severe malaria and it has been shown to reduce the duration of coma in children with cerebral malaria. This pilot study was performed to assess pharmacokinetics, safety and efficacy of PTX in African children with cerebral malaria. METHODS: Ten children admitted to the high dependency unit of the Kilifi District Hospital in Kenya with cerebral malaria (Blantyre coma score of 2 or less) received quinine plus a continuous infusion of 10 mg/kg/24 hours PTX for 72 hours. Five children were recruited as controls and received normal saline instead of PTX. Plasma samples were taken for PTX and tumour necrosis factor (TNF) levels. Blantyre Coma Score, parasitemia, hematology and vital signs were assessed 4 hourly. RESULTS: One child (20%) in the control group died, compared to four children (40%) in the PTX group. This difference was not significant (p = 0.60). Laboratory parameters and clinical data were comparable between groups. TNF levels were lower in children receiving PTX. CONCLUSIONS: The small sample size does not permit definitive conclusions, but the mortality rate was unexpectedly high in the PTX group.

Introduction: The provision of health care services in Kenya was devolved from the national government to the counties in 2013. Evidence suggests that health system performance in Kenya remains poor. The main issue is poor leadership resulting in poor health system performance. However, most training in Kenya focuses on "leaders" (individual) development as opposed to "leadership" training (development of groups from an organization). The purpose of that study was to explore the impact of leadership training on health system performance in selected counties in Kenya. Methods: A quasi-experimental time-series design was employed. Pretest, posttest control-group design was utilized to find out whether the leadership development program positively contributed to the improvement of health system performance indicators compared with the non-trained managers. Questionnaires were administered to 31 trained health managers from the public, private for-profit, and private not-for-profit health institutions within the same counties. Results: The pretest and posttest means for all the six health system (HS) pillar indicators of the treatment group were higher than those of the control group. The regression method to estimate the DID structural model used to calculate the "fact" and "counterfactual" revealed that training had a positive impact on the intended outcome on the service delivery, information, leadership and governance, human resources, finance, and medical products with impact value ≥1 (57.2). Conclusion: The study findings support both hypotheses that trained health care management teams had a significant difference in the implementation status of priority projects and, hence, had a significant impact on health system performance indicators compared with non-trained managers.

OBJECTIVE: To identify what women want in a delivery health facility and how they rank the attributes that influence the choice of a place of delivery. DESIGN: A discrete choice experiment (DCE) was conducted to elicit rural women's preferences for choice of delivery health facility. Data were analysed using a conditional logit model to evaluate the relative importance of the selected attributes. A mixed multinomial model evaluated how interactions with sociodemographic variables influence the choice of the selected attributes. SETTING: Six health facilities in a rural subcounty. PARTICIPANTS: Women aged 18-49 years who had delivered within 6 weeks. PRIMARY OUTCOME: The DCE required women to select from hypothetical health facility A or B or opt-out alternative. RESULTS: A total of 474 participants were sampled, 466 participants completed the survey (response rate 98%). The attribute with the strongest association with health facility preference was having a kind and supportive healthcare worker (ß=1.184, p<0.001), second availability of medical equipment and drug supplies (ß=1.073, p<0.001) and third quality of clinical services (ß=0.826, p<0.001). Distance, availability of referral services and costs were ranked fourth, fifth and sixth, respectively (ß=0.457, p<0.001; ß=0.266, p<0.001; and ß=0.000018, p<0.001). The opt-out alternative ranked last suggesting a disutility for home delivery (ß=-0.849, p<0.001). CONCLUSION: The most highly valued attribute was a process indicator of quality of care followed by technical indicators. Policymakers need to consider women's preferences to inform strategies that are person centred and lead to improvements in quality of care during delivery.

OBJECTIVE: To examine how women living in an informal settlement in Nairobi perceive the quality of maternity care and how it influences their choice of a delivery health facility. DESIGN: Qualitative study. SETTINGS: Dandora, an informal settlement, Nairobi City in Kenya. PARTICIPANTS: Six focus group discussions with 40 purposively selected women aged 18-49 years at six health facilities. RESULTS: Four broad themes were identified: (1) perceived quality of the delivery services, (2) financial access to delivery service, (3) physical amenities at the health facility, and (4) the 2017 health workers' strike.The four facilitators that influenced women to choose a private health facility were: (1) interpersonal treatment at health facilities, (2) perceived quality of clinical services, (3) financial access to health services at the facility, and (4) the physical amenities at the health facility. The three barriers to choosing a private facility were: (1) poor quality clinical services at low-cost health facilities, (2) shortage of specialist doctors, and (3) referral to public health facilities during emergencies.The facilitators that influenced women to choose a public facility were: (1) physical amenities for dealing with obstetric emergencies and (2) early referral to public maternity during antenatal care services. Barriers to choosing a public facility were: (1) perception of poor quality clinical services, (2) concerns over security for newborns at tertiary health facilities, (3) fear of mistreatment during delivery, (4) use of unsupervised trainee doctors for deliveries, (5) poor quality of physical amenities, and (6) inadequate staffing. CONCLUSION: The study provides insights into decision-making processes for women when choosing a delivery facility by identifying critical attributes that they value and how perceptions of quality influence their choices.

This paper reports on an exploratory investigation of the influence of five different fatalistic belief constructs (divine control, luck, helplessness, internality, and general fatalism) on three classes of self-reported pedestrian behaviours (memory and attention errors, rule violations, and aggressive behaviours) and on respondents' general attitudes to road safety, and how relationships between constructs differ across countries. A survey of over 3400 respondents across Bangladesh, China, Kenya, Thailand, the UK, and Vietnam revealed a similar pattern for most of the relationships assessed, in most countries; those who reported higher fatalistic beliefs or more external attributions of causality also reported performing riskier pedestrian behaviours and holding more dangerous attitudes to road safety. The strengths of relationships between constructs did, however, differ by country, behaviour type, and aspect of fatalism. One particularly notable country difference was that in Bangladesh and, to a lesser extent, in Kenya, a stronger belief in divine influence over one's life was associated with safer attitudes and behaviours, whereas where significant relationships existed in the other countries the opposite was true. In some cases, the effect of fatalistic beliefs on self-reported behaviours was mediated through attitudes, in other cases the effect was direct. Results are discussed in terms of the need to consider the effect of locus of control and attributions of causality on attitudes and behaviours, and the need to understand the differences between countries therein.

This article gives an overview of some of the ongoing challenges that are faced in the prevention, diagnosis and treatment of malaria. Malaria causes approximately 881,000 deaths every year, with nine out of ten deaths occurring in sub-Saharan Africa. In addition to the human burden of malaria, the economic burden is vast. It is thought to cost African countries more than US$12 billion every year in direct losses. However, great progress in malaria control has been made in some highly endemic countries. Vector control is assuming a new importance with the significant reductions in malaria burden achieved using combined malaria control interventions in countries such as Zanzibar, Zambia and Rwanda. The proportion of patients treated for malaria who have a confirmed diagnosis is low in Africa compared with other regions of the world, with the result that anti-malarials could be used to treat patients without malaria, especially in areas where progress has been made in reducing the malaria burden and malaria epidemiology is changing. Inappropriate administration of anti-malarials could contribute to the spread of resistance and incurs unnecessary costs. Parasite resistance to almost all commonly used anti-malarials has been observed in the most lethal parasite species, Plasmodium falciparum. This has presented a major barrier to successful disease management in malaria-endemic areas. ACT (artemisinin-based combination therapy) has made a significant contribution to malaria control and to reducing disease transmission through reducing gametocyte carriage. Administering ACT to infants and small children can be difficult and time consuming. Specially formulating anti-malarials for this vulnerable population is vital to ease administration and help ensure that an accurate dose is received. Education of healthworkers and communities about malaria prevention, diagnosis and treatment is a vital component of effective case management, especially as diagnostic policies change. Preventing resistance emerging to both ACT and insecticides used in vector control remains an ongoing challenge in an era of changing malaria epidemiology.
