BACKGROUND:Invasive pneumococcal disease (IPD) still causes significant morbidity and mortality. In this study, we describe incidence, risk factors, manifestations, and outcome of IPD in Southwest Sweden during the first eleven years after the introduction of conjugate pneumococcal vaccines in the childhood vaccination program in 2009. METHODS:Clinical data from 2,288 consecutive episodes of IPD in Region Västra Götaland, Sweden during 2009-2019 were retrospectively collected from medical records. Incidence rates were calculated using population data from the same period. The results were compared to data from three previous studies from the same geographical area with a total follow-up of 56 years. RESULTS:The incidence of all IPD episodes in 2009-2019 was 12.8/100,000/year. A very high IPD incidence was seen in patients with multiple myeloma (1,497/100,000) and chronic lymphocytic leukemia (505/100,000). Meningitis occurred in 26% of the IPD episodes in children <2 years compared to 4.3% in the age group ≥65 years (12/46 versus 60/1,403; p < 0.001). The opposite was found for pneumonia, which accounted for 22% of the IPD episodes in children <2 years compared to 77% among the elderly (10/46 vs. 1,085/1,403; p < 0.001). In 604 IPD episodes (26.4%), one or more complications were observed, most commonly parapneumonic effusion and empyema. When data were compared with the previous study period, the IPD incidence in children <2 years declined from 22.5 in 1996-2008 to 10.7 per 100,000 in 2009-2019, while only a modest reduction was observed in adults ≥65 years (from 45.0/100,000 to 41.2/100,000). The overall case fatality rate (CFR) increased from 9.9% in 1996-2008 to 12.9% in 2009-2019, which could be explained by increased patient age and underlying comorbidity. CONCLUSIONS:A substantial decrease in IPD incidence was seen in infants and young children but not in the elderly during the first eleven years after the introduction of the general childhood pneumococcal vaccination program. Patients with hematological malignancies remain a high-risk group of IPD.

Abstract Immunoglobulins (Ig) are essential for protection against invading pneumococci but are not routinely analyzed in patients with invasive pneumococcal disease (IPD). In this prospective study, we assessed the prevalence of monoclonal Ig (M protein) and analyzed Ig concentrations in sera from 156 adult IPD patients (median age 70 years). Patients were sampled during acute infection ( n = 153) and in the convalescence phase 2–4 months after acute infection ( n = 76). Sixty-four sex- and age-matched individuals without IPD served as controls. During infection, M protein was detected in 22% (31/141) of patients without previously known hematological malignancy as compared with 5% of the controls ( p = 0.002). Seven of these patients were subsequently diagnosed with a hematological malignancy, including multiple myeloma, Waldenstrom macroglobulinemia, and mantle cell lymphoma. Another 12 patients were diagnosed with monoclonal gammopathy of undetermined significance (MGUS). Convalescence levels of IgA, IgG2, or IgG4 were below the reference intervals in 16–20% of patients and 0–2% of controls. Three patients were diagnosed with a primary Ig deficiency, and seven patients started Ig replacement therapy. Our findings suggest that assessment of M protein and Ig levels could be considered in adults with IPD, as an episode of IPD may unmask a previously undiagnosed B-cell malignancy or immunodeficiency.

Antimicrobial resistance remains a pressing global challenge, driving efforts worldwide to reduce antibiotic consumption and mitigate its emergence and spread. The aim of this study was to describe how utilizing antibiotics for children under five years of age in the Democratic Republic of the Congo (DRC) is experienced by various healthcare providers. A phenomenographic approach was employed to analyse data from individual interviews with 14 healthcare workers of the Eastern DRC, including medical doctors, nurses and practicing pharmacists. Two overarching themes with their corresponding categories emerged: “Factors influencing antibiotic use” and “Operating within a weak healthcare system”. Healthcare providers consistently described widespread self-medication practices in children, driven largely by financial constraints within the population. Although many providers recognized the risks associated with inappropriate antibiotic use, their decisions were heavily influenced by systemic limitations and community expectations. A major concern raised was the increasing failure of antibiotics in treatment. This study highlights the complex factors shaping antibiotic use and prescription practices in Eastern DRC, where healthcare workers operate within a fragmented healthcare system. Addressing antibiotic resistance in such settings requires coordinated local and global efforts focused on promoting responsible antibiotic use, strengthening healthcare infrastructure, providing continuous education, establishing national guidelines, and improving community awareness and access to quality care.

IntroductionPneumococcal conjugate vaccines have reduced severe disease attributed to vaccine-type pneumococci in children. However, the effect is dependent on serotype distribution in the population and disease development may be influenced by co-occurrence of viral and bacterial pathogens in the nasopharynx.MethodsFollowing introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in Tanzania we performed repeated cross-sectional surveys, including 775 children below 2 years of age attending primary healthcare centers. All children were sampled from nasopharynx and pneumococci were detected by single-target PCR. Pneumococcal serotypes/groups and presence of viruses and other bacteria were determined by two multiplex PCR assays.ResultsThe prevalence of PCV13 vaccine-type pneumococci decreased by 50%, but residual vaccine-types were still detected in 21% of the children 2 years after PCV13 introduction. An increase in the non-vaccine-type 15 BC was observed. Pneumococci were often co-occurring with Haemophilus influenzae, and detection of rhino/enterovirus was associated with higher pneumococcal load.DiscussionWe conclude that presence of residual vaccine-type and emerging non-vaccine-type pneumococci in Tanzanian children demand continued pneumococcal surveillance. High co-occurrence of viral and bacterial pathogens may contribute to the disease burden and indicate the need of multiple public health interventions to improve child health in Tanzania.

BACKGROUND:Three billion people in low- and middle-income countries are exposed to household air pollution as they use biomass fuel for cooking. We investigated the associations between solid fuel use and nasopharyngeal (NP) inflammation, as well as the associations between high pneumococcal density and NP inflammation, in mothers and children in rural and urban Ethiopia. MATERIALS AND METHODS:Sixty pairs of mothers (median age, 30 years; range, 19-45 years) with a child (median age, 9 months; range, 1-24 months) were included from rural Butajira (n = 30) and urban Addis Ababa (n = 30) in Ethiopia. The cohort was randomly selected from a previous study of 545 mother/child pairs included 2016. Questionnaire-based data were collected which included fuel type used (solid: wood, charcoal, dung or crop waste; cleaner: electricity, liquefied petroleum gas). Nasopharyngeal (NP) samples were collected from all mothers and children and analyzed for the levels of 18 cytokines using a Luminex immunoassay. Pneumococcal DNA densities were measured by a real-time multiplex PCR and a high pneumococcal density was defined as a cyclic threshold (Ct) value ≤ 30. RESULTS:Mothers from rural areas had higher median CXCL8 levels in NP secretions than those from urban areas (8000 versus 1900 pg/mL; p < 0.01), while rural children had slightly higher IL-10 levels than those from the urban area (26 vs 13 pg/mL; p = 0.04). No associations between fuel type and cytokine levels were found. However, a high pneumococcal density was associated with higher levels of cytokines in both mothers (CCL4, CXCL8, IL-1β, IL-6 and VEGF-A) and children (CCL4, CXCL8, IL-1β, IL-6 and IL-18). CONCLUSIONS:No significant associations were found between solid fuel use and NP inflammation in Ethiopian mothers and children, but the inflammatory activity was higher in individuals living in the rural compared to the urban area. In addition, high cytokine levels were associated with high pneumococcal density in both mothers and children, indicating a significant impact of NP pathogens on inflammatory mediator levels in upper airways.

BACKGROUND:Over 90% of Ethiopians still rely on solid fuels for cooking food. The pollution from the burning process causes adverse respiratory outcomes including respiratory infections. This study aimed to assess the association of the pollution with nasopharyngeal occurrence of potential pathogens.METHODS:We conducted a comparative cross-sectional study in urban and rural settings in Ethiopia in 2016. Questionnaire-based data were collected from 168 mothers and 175 children aged below two years. Multiplex real-time PCR assays were performed on nasopharyngeal secretions for detection of bacteria and viruses and for the identification of pneumococcal serotypes/groups.RESULTS:High rates of bacteria and viruses in the nasopharynx were detected by PCR among both the children and the mothers. Among the detected viruses, enterovirus was more commonly detected among rural children than among children from urban areas. Streptococcus pneumoniae and Haemophilus influenzae were both more prevalent among children and mothers from rural areas compared with urban groups and among those using solid fuels compared with cleaner fuel users. Children from rural households using solid fuels and children whose mothers had educational status below high school had four times higher odds for detection of S. pneumoniae compared with those households using cleaner energy or those children having mothers with a higher educational status, respectively. One or more serotype/serogroup was identified in about 40% of the samples that were positive for pneumococci. Out of all identified serotypes/serogroups, 43% in the children and 45% in the mothers belonged to PCV13, indicating the larger majority of detected pneumococci being non-PCV13 serotypes.CONCLUSION:This study presented a high carriage rate of S. pneumoniae and H. influenzae among both children and their mothers, especially in rural areas and among solid fuel users. Thus, interventions should target cleaner energy sources to the public and promote maternal education.

Abstract Background: Antimicrobial resistance is a serious threat to the global achievements in child health thus far. Previous studies have found high use of antibiotics in children in Northern Tanzania, but the experiences of the primary care-givers, who play a key role in accessing and administering antibiotics for the sick child, has remained largely unknown. We aimed to understand mothers’ conceptions of antibiotic use in their children, which is of importance when forming strategies to improve antibiotic use in the community. Method: A qualitative study including eight focus group discussions with mothers of under-five children in Moshi urban and rural districts, Northern Tanzania, was performed during 2019. The discussions were recorded, transcribed verbatim, translated to English and analysed according to the phenomenographic approach. Findings: Three conceptual themes emerged during analysis; (1) conceptions of disease and antibiotics, (2) accessing treatment and (3) administering antibiotics. Antibiotics were often perceived as a universal treatment for common symptoms or diseases in children with few side-effects. Although mothers preferred to attend a healthcare facility, unforeseen costs, long waits and lack of financial support from their husbands, pose barriers for care-seeking. However, pharmacies were perceived as a cheap and convenient option to access previously used or prescribed antibiotics. Some mothers sought advice from a trusted neighbour regarding when to seek care, thus resembling the function of the community health worker (CHW). Conclusions: To improve antibiotic use in children under five years of age in Northern Tanzania, we suggest targeting behaviour of individuals alone will not be sufficient. Improving structures, including the healthcare system and socio-economic inequality, are needed for sustained results. In the meantime, equipping CHWs to support women in appropriate healthcare seeking for their children, may be a feasible target for intervention.

PURPOSE:This study explores the preferences of patients with cancer, family caregivers, and the general public regarding breaking bad news in an Ethiopian oncology setting.METHODS:The study was conducted at Tikur Anbessa (Black Lion) Specialized Hospital. The sample consists of patients with a confirmed cancer diagnosis, their family caregivers, and representatives from the general public with 150 subjects per cohort. The study used a comparative cross-sectional design and multivariable data analysis.RESULTS:The patients would like to be informed, which contradicts the preferences of family caregivers. This creates an ethical dilemma for staff in terms of how much they involve their patients in clinical decision making. The patients also indicate that information should not be withheld from them. By contrast, the general public prefers information about poor life expectancy to be communicated to family only, which may reflect a widespread public perception of cancer as a deadly disease.CONCLUSION:The findings indicate the complexity of communication-related preferences concerning breaking bad news in oncology care in Ethiopia. It requires oncologists to probe patient attitudes before information disclosure to find a balance between involving patients in communication at the same time as keeping a constructive alliance with family caregivers.

e24116 Background: Limited research is available about COVID 19 pandemic in Ethiopia in general and in relation to cancer care in particular. Ethiopia reported the first COVID-19 in March, 2020. The number of cases is increasing, putting much pressure on oncology care. This study examines what the Ethiopian cancer patients and their caregivers knew about COVID 19 after the initial stages of the pandemic. It also assesses the information needs, psychological experiences as well as the impact of pandemic on oncologist-patient-caregiver communication and treatment process. Methods: A cross-sectional study was conducted among 200 participants (100 cancer patients and 100 caregivers) at the initial stage of pandemic (May 1 - June 30, 2020) at Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia. Data was collected using a pre-tested, structured questionnaire to assess knowledge and perceptions on COVID-19. Ethics approval was obtained from the Ethical Review Board of TASH (04/14/2015) and the Ethical Review Board of Western Sweden (DNR 520-18). Results: The results indicate that though both cancer patients and their caregivers show a high awareness of and knowledge about COVID 19, they need more information about the risks specific to cancer patients. The respondents are also concerned about the risks of pandemic outbreak in Ethiopia and its impact on availability of cancer care treatments in the country. The respondents report experiencing psychological concerns in relation to the pandemic. The higher educated patients and caregivers report being more concerned than the lower educated respondents. Delays in appointments and therapy are the main concerns in relation to cancer care. Further, both patients and caregivers experience that the restrictions on the number of caregivers present during interactions with oncologists negatively influence communication, resulting in relatives being excluded and patients experiencing loneliness and lack of support. Conclusions: Getting a better insight into knowledge and awareness of COVID-19 among cancer patients and their caregivers is essential for managing the effects of pandemic in cancer care. To our knowledge, there was no similar study in Ethiopia. The results of the study contribute to insights into patient and caregiver awareness of COVID 19, essential for adoption of health care protective practices, providing information and managing oncologist-patient-caregiver communication.

The use of solid fuel, known to emit pollutants which cause damage to human health, is the primary energy option in Ethiopia. Thus, the aim of this study was to measure the level of household air pollution by using the 24-h mean concentration of fine particulate matter (PM2.5) in 150 randomly recruited households in rural Butajira, Ethiopia. Data relating to household and cooking practices were obtained by conducting face-to-face interviews with the mothers. The 24-h mean (standard deviation) and median PM2.5 concentrations were 410 (220) and 340 µg/m3, respectively. Households using only traditional stoves and those who did not open the door or a window during cooking had a significantly higher mean concentration compared with their counterparts. There is a statistically significant correlation between the mean concentration of PM2.5 and the self-reported cooking duration. The pollution level was up to 16 times higher than the WHO 24-h guideline limit of 25 μg/m3, thus leaving the mothers and children who spend the most time at the domestic hearth at risk of the adverse health effects from solid fuel use in Ethiopia. Thus, effective short- and long-term interventions are urgently needed.

Introduction acute lower respiratory infections (ALRI) are a leading killer of children under five worldwide including the Democratic Republic of the Congo (DR Congo). We aimed to determine the morbidity and case fatality rate due to ALRI before and after introduction of the 13-valent pneumococcal conjugate vaccine (PVC13) in DR Congo 2013. Methods data were collected from medical records of children with a diagnosis of ALRI, aged from 2 to 59 months, treated at four hospitals in the Eastern DR Congo. Two study periods were defined; from 2010 to 2012 (before introduction of PCV13) and from 2014 to 2015 (after PCV13 introduction). Results out of 21,478 children admitted to the hospitals during 2010-2015, 2,007 were treated for ALRI. The case fatality rate among these children was 4.9%. Death was significantly and independently associated with malnutrition, severe ALRI, congenital disease and symptoms of fatigue. Among the ALRI hospitalised children severe ALRI decreased from 31% per year to 18% per year after vaccine introduction (p = 0.0002) while the fatality rate remained unchanged between the two study periods. Following introduction of PCV13, 63% of the children diagnosed with ALRI were treated with ampicillin combined with gentamicin while 33% received ceftriaxone and gentamicin. Conclusion three years after PCV13 introduction in the Eastern part of the DR Congo, we found a reduced risk of severe ALRI among children below five years. Broad-spectrum antibiotics were frequently used for the treatment of ALRI in the absence of any microbiological diagnostic support.

BackgroundCancer is a major burden in Ethiopia. The Oncology Department of Tikur Anbessa (Black Lion) Specialized Hospital in Addis Ababa is the sole specialist unit for cancer care in the country. With only a handful of oncologists, a lack of resources, and a huge patient load, the work is challenging, especially in terms of achieving effective and ethical patient consultations. Patients, usually accompanied by family members, often wait for a long time to receive medical attention and frequently depart without treatment. Handling consultations effectively is essential to help patients as much as possible within such limitations. ObjectiveThe project has the following three main aims: (1) to enhance and expand the understanding of communicative and associated ethical challenges in Ethiopian cancer care; (2) to enhance and expand the understanding of the implications and use of person- and family-centered solutions to address such communicative challenges in practice; and (3) to plan and evaluate interventions in this area. MethodsThis project develops and consolidates a research collaboration to better understand and mitigate the communicative challenges in Ethiopian cancer care, with a focus on the handling and sharing of decision making and ethical tension among patients, staff, and family. Using theoretical models from linguistics, health communication, and health care ethics, multiple sources of data will be analyzed. Data sources currently include semistructured interviews with Ethiopian staff (n= 16), patients (n= 54), and family caregivers (n= 22); survey data on cancer awareness (n=150) and attitudes toward breaking bad news (n=450); and video recordings of medical consultations (n=45). In addition, we will develop clinical and methodological solutions to formulate educational interventions. ResultsThe project was awarded funding by the Swedish Research Council in December 2017 for the period 2018 to 2021. The research ethics boards in Sweden and Ethiopia approved the project in May 2018. The results of the studies will be published in 2020 and 2021. ConclusionsThe project is the first step toward providing unique and seminal knowledge for the specific context of Ethiopia in the areas of physician-patient communication research and ethics. It contributes to the understanding of the complexity of the role of family and ethical challenges in relation to patient involvement and decision making in Ethiopia. Improved knowledge in this area can provide a fundamental model for ways to improve cancer care in many other low-resource settings in Africa and the Middle East, which share central cultural prerequisites, such as a strong patriarchal family structure, along with strong and devout religiosity. The project will also serve to develop greater understanding about the current challenges in Western health systems associated with greater family and patient participation in decision making. In addition, the project will contribute to improving the education of Ethiopian health professionals working in cancer care by developing a training program to help them better understand and respond to identified challenges associated with communication.

Background: Few studies have focused on the treatment of tuberculosis (TB) during pregnancy. This study aimed to evaluate the risk of adverse events, particularly liver toxicity, in pregnant women during treatment for active TB. Methods: We conducted a retrospective study on pregnant and age-matched non-pregnant women receiving treatment for active TB at four hospitals in Western Sweden between 1992 and 2017. Results: A total of 135 women were included, 40 pregnant and 95 non-pregnant. The frequency of severe hepatotoxicity was 40% in pregnant women and 6% among non-pregnant women (p < 0.001) (odds ratio 9.9; 95% confidence interval 3.5-28.0). Temporary drug withdrawal due to elevated transaminase levels was more frequent for pregnant than non-pregnant women (40% vs 9.5%; p < 0.001) (odds ratio 6.4; 95% confidence interval 2.5-16.2). There was one fatal case of hepatotoxicity in a pregnant woman. Conclusion: Severe hepatotoxicity was significantly more frequent in pregnant women compared to nonpregnant women. Careful monitoring of liver transaminases while receiving TB treatment during pregnancy is mandatory, as well as ensuring adequate measures with adjustment of drug regimen and temporary drug withdrawals when a rise in liver enzymes is noted.

Background: There is a limited knowledge of the impact of being human immunodeficiency virus (HIV)-positive on migrants living in Sweden. It is therefore important to gain a general awareness of this issue in order to maintain the wellbeing of this vulnerable group of patients and to develop an adequate social support network. Objective: The aim of this study was to explore HIV-positive migrants' experiences of their life situations, living in Sweden. Method: A qualitative, exploratory study was performed using semi-structured interviews with 14 HIV-positive migrants, aged 29-55 years, and analyzed with qualitative content analysis. The participants were recruited from three clinics for infectious diseases in western Sweden. Results: The results are presented in the following three categories: ' Vulnerability in social relationships', 'Fear of disclosure", and 'Resilience'. The results illustrated the participants' experiences of vulnerability in their social relationships, fear of disclosing HIV status, feeling lonely and stigmatized, and lacking social network and support. Furthermore, the results illustrated participants' challenges in finding a partner, due to their fear of being recognized because of their HIV-infection. However, the result indicated participants' struggling for a normal life with integrity, and that their need to look positively at life. Conclusions: In the actual study loneliness, fear of disclosure, perceived stigma, and the lack of a social network had significant impact on the life situations of the HIV positive migrants. Fear of disclosure and the challenge of finding a partner and friends were the main obstacles. It is crucial to increase access for these patients to supporting networks that will promote their empowerment and trust.

Abstract Background Acute pneumonia remains a leading cause of death among children below 5 years of age in the Democratic Republic of the Congo (DR Congo), despite introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in 2013. Pathogens in the nasopharynx of hospitalised children with pneumonia have not been studied previously in DR Congo. Here we compare clinical characteristics, risk factors and nasopharyngeal occurrence of bacteria and viruses between children with severe and non-severe pneumonia Methods Between June 2015 and June 2017, 116 children aged from 2 to 59 months hospitalised due to radiologically confirmed pneumonia at Panzi referral university hospital, Bukavu, eastern DR Congo were included in the study and sampled from nasopharynx. A multiplex real-time PCR assay for detection of 15 different viruses and 5 bacterial species was performed and another multiplex PCR assay was used for pneumococcal serotype/serogroup determination. Results During the study period 85 (73%) of the children with radiologically confirmed pneumonia met the WHO classification criteria of severe pneumonia and 31 (27%) had non-severe pneumonia. The fatality rate was 9.5%. Almost all (87%) children were treated with antibiotics before they were hospitalised, in most cases with amoxicillin (58%) or trimethoprim-sulfamethoxazole (20%). Children with severe pneumonia were more commonly treated with trimethoprim-sulfamethoxazole before hospitalisation than children with non-severe pneumonia (OR 4.75; 95%CI 1.04–21.65, p = 0.043), as were children who died at the hospital as compared to children who recovered (OR 3.98; 95%CI 1.1–14.4, p = 0.035). Any viral or bacterial nucleic acids present at high levels in nasopharynx were significantly associated with severe pneumonia as compared with non-severe cases (52% versus 29%, p = 0.032). High levels of pneumococci or respiratory syncytial virus (RSV) were associated with fatal outcome. One or more serotypes/serogroups could be identified in 61 patients, and out of all identified pneumococcal serotypes 31/83 (37%) were non-PCV13 serotypes. Conclusions The occurrence of any bacteria or any viruses at high levels, irrespective of species, was associated with severe pneumonia. High levels of RSV or pneumococci were associated with higher risk of fatality. Pre-hospitalisation treatments with broad spectrum antibiotics were common but were associated with a more severe outcome.

Background: Ethiopia was among the 15 countries that, together accounted for 64% of the world's severe episodes of pneumonia among children below the age of 5 in 2011. To reduce this burden, the 10-valent pneumococcal conjugate vaccine (PCV 10) was introduced into the general childhood national immunization program in Ethiopia in 2011. However, there is little evidence on its cost-effectiveness, and the aim of this study was to estimate the cost-effectiveness of the introduction of PCV 10 vaccination in the Ethiopian setting. Methods: The cost-effectiveness analysis was carried out based on a quasi-experimental evaluation of implementing PCV 10 at the Butajira rural health program site in Ethiopia. The intervention and the control groups consisted 876 and 1010 children, respectively. Using data from program site's surveillance system database as a framework, health outcome and vaccination data were collected from medical records, immunization registration books and reports. Disability-Adjusted Life Year (DALY) was a main health outcome metric complimented by incidence of acute lower respiratory infection/1000-person years. Vaccination and treatment costs were collected by document review and cross-sectional household survey. Results: In the intervention cohort, 626 of 876 (71.5%) children received PCV 10 vaccination. Until the first year of life, the incidence of acute lower respiratory infection was higher in the intervention group. After the first year of life, the incidence rate was 35.2 per 1000-person years in the intervention group compared to 60.4 per 1000-person years in the control group. The incremental cost-effectiveness ratio (ICER) per averted DALY for the intervention group during the total follow-up period was (2013 US$) 394.3 (undiscounted) and 413.8 (discounted). The ICER per averted DALY excluding the first year of life was (2013 US$) 225 (undiscounted) and 292.7 (discounted). Conclusion: Compared to the WHO's suggested cost-effectiveness threshold value, the results indicate that the general childhood PCV 10 vaccination was a cost-effective intervention in the Butajira rural health program site.

Adherence to antiretroviral treatment (ART) is of utmost importance to reduce the risk of vertical transmission of HIV. We enrolled 106 patients from two Prevention of mother-to-child transmission (PMTCT) clinics in Dar es Salaam in September- November 2016. Study participants were given structured standardized questionnaires regarding their self-estimated adherence and barriers and enablers to adherence. Good adherence was defined as taking ?95% of the pills as prescribed. About 70% of the participants achieved this level of adherence. The odds ratios for poor adherence among women with medium and poor family support were 5.69 (95% CI: 1.36-23-75) and 6.86 (95% CI: 1.89-24.96) respectively compared to good support. A large portion of the women failed to reach the high set limit for adherence. Increased spousal involvement and support could help many women to achieve good adherence.

OBJECTIVES:To determine the antibiotic susceptibility and serotype distribution of colonizing Streptococcus pneumoniae in Tanzanian children. Serial cross-sectional surveys were performed following the national introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in December 2012. METHODS:A total of 775 children less than 2 years of age were recruited at primary health centres in Moshi, Tanzania between 2013 and 2015, and samples were obtained from the nasopharynx. S. pneumoniae were isolated by culture and tested for antibiotic susceptibility by disc diffusion and E-test methods; molecular testing was used to determine serotype/group. RESULTS:Penicillin non-susceptibility in the isolated pneumococci increased significantly from 31% (36/116) in 2013, to 47% (30/64) in 2014 and 53% (32/60) in 2015. Non-susceptibility to amoxicillin/ampicillin and ceftriaxone was low (n=8 and n=9, respectively), while 97% (236/244) of the isolates were non-susceptible to trimethoprim-sulfamethoxazole. The majority of the children (54%, n=418) had been treated with antibiotics in the past 3 months, and amoxicillin/ampicillin were overall the most commonly used antibiotics. Carriage of penicillin-non-susceptible pneumococci was more common in children with many siblings. The prevalence of PCV13 serotypes among the detected serotypes/groups decreased from 56% (40/71) in 2013 to 23% (13/56) in 2015. CONCLUSIONS:Penicillin non-susceptibility in S. pneumoniae colonizing Tanzanian children increased during an observation period shortly after the introduction of PCV13. Measures to ensure rational use of antibiotics and more effective systems for surveillance of antibiotic resistance and serotype distribution are needed to assure continued effective treatment of pneumococcal disease.

Exposure to household air pollution has been linked to chronic obstructive pulmonary disease, respiratory symptoms and reduced lung function. This study aims to assess respiratory symptoms and lung function among Ethiopian women in relation to exposure to HAP. We conducted a cross-sectional study among non-smoking women responsible for household cooking. Data was collected on socio-demographic characteristics, respiratory symptoms and risk factors using a validated questionnaire. Spirometry with reversibility testing was performed according to American Thoracic Society/European Respiratory Society guidelines. We used independent t-test and multivariable logistic regression to compare the means and measure association respectively. A total of 545 women participated in the study out of which 231 (42.3%) performed spirometry with at least three acceptable manoeuvres. Everyone in the rural group and 43% of the urban group were exposed to HAP from solid fuels during cooking. The odds of developing at least one respiratory symptom when compared with those using cleaner fuels are twice as high for women cooking within the living house. We also found significantly lower forced expiratory volume in the first second (FEV1) (L) among solid fuels users compared with cleaner energy users. Given the larger population settlement in the rural areas and the use of solid fuel as the only energy source, there is a higher risk of developing chronic respiratory health problems for those women in Ethiopia.
