- Introduction: Pneumococcal 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. Methods: Following 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. Results: The 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. Discussion: We 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.

- This study explores the preferences of cancer patients, family caregivers, and the general public regarding breaking bad news in an Ethiopian oncology setting. The research 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. A comparative cross-sectional study design and a multivariable analysis were used. The patients would like to be informed, which contradicts the perceptions 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 not to be withheld from them. In contrast, the general public prefers information about poor life expectancy to be communicated to family only, which may reflect widespread public perception of cancer as a deadly disease. The findings indicate the complexity of communication concerning breaking bad news in oncology care in Ethiopia. It requires oncologists to probe patient attitudes before information disclosure in order to find a balance between involving patients in communication at the same time as keeping a constructive alliance with family caregivers.

- 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.

- 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.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.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.Severe hepatotoxicity was significantly more frequent in pregnant women compared to non-pregnant 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.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Cancer is a major burden in Ethiopia. The Oncology Department of Tikur Anbessa (Black Lion) Specialized Hospital (TASH) in Addis Ababa is the country's sole specialist unit for cancer care. 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 in order to help patients as much as possible within such limitations. OBJECTIVE: The project addresses 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. METHODS: This 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 tensions between 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 semi-structured interviews with the Ethiopian staff, patients, and family caregivers (91), survey data on cancer awareness (150) and attitudes to breaking bad news (450), and video-recordings of medical consultations (45). In addition, we will also develop clinical and methodological solutions to formulate educational interventions. RESULTS: The project was awarded funding by the Swedish Research Council in December 2017 for the period 2018-2021. The research ethics board in Sweden and in Ethiopia approved the conduct of the project in May 2018. The results from the studies will be published in 2020 and 2021. CONCLUSIONS: The project is a first step towards producing unique and seminal knowledge for the specific context of Ethiopia in the area of physician-patient communication research and ethics. It contributes to an understanding of the complexity around 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, combined with strong and devout religiosity). The project will also serve to develop greater understanding about current challenges in Western health systems associated with greater family and patient participation in decision making. In addition, the project will also 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.

- BackgroundThe pneumococcal conjugate vaccine PCV7 was introduced in Southwest Sweden in the child vaccination program in 2009, followed by PCV13 in 2010 and PCV10 in 2015. In this retrospective cohort study we assessed the pneumococcal serotype distribution in relation to predisposing factors, clinical manifestations and outcome during seven years after PCV introduction.MethodsClinical data from 1278 patients with 1304 episodes of invasive pneumococcal disease (IPD) between January 2009 and December 2015 in Region Vastra Gotaland, Sweden, were retrospectively collected from medical records. Pneumococcal isolates were serotyped by gel diffusion and/or Quellung reactions performed at the Public Health Agency in Sweden. Associations between serotypes and clinical characteristics were statistically evaluated by use of Fisher's exact test, Mann-Whitney U test and Logistic regression analysis, whereas IPD episodes caused by serotypes over time were analyzed by Mantel-Haenszel chi-square test.ResultsWith the exception of serotype 3, the prevalence of PCV13 serotypes decreased during the study period, from 76% (n=157) of all IPD episodes in 2009 to 25% (n=42) in 2015 (p<0.001) while non-PCV13 serotypes increased, mainly among patients 65years and in patients with predisposing factors, including cardiovascular disease, pulmonary disease and malignancy (p<0.001 for all). Patients with predisposing factors, including those with malignancy, immune deficiency or renal disease, were more likely to have IPD caused by a serotype not included in PCV13 rather than a vaccine-included serotype. Serotype 3 was associated with intensive care unit admissions while serotype 1 and 7F caused IPD among healthier and younger patients. PCV13 serotypes were associated with invasive pneumonia, and non-PCV13 serotypes were associated with bacteremia with unknown focus and with manifestations other than pneumonia or meningitis.ConclusionsNon-PCV13 serotypes caused the majority of IPD cases in Southwest Sweden, especially in patients 65years and in patients with predisposing factors. Serotype 3, included in PCV13, was prevalent and often caused severe disease.

- 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. Potential 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%). The frequency of potential pathogens in the nasopharynx of the children was high, and any viral or bacterial nucleic acids present at high levels, irrespective of species or type, were significantly associated with severe pneumonia as compared with non-severe cases (52% versus 29%, p = 0.032). White blood cell count > 20,000/mu L and C-Reactive Protein > 75 mg/dL were associated with severe pneumonia at admission. Fatal outcome was in the multivariable analysis associated with having a congenital disease as an underlying condition. One or more pneumococcal serotypes/serogroups could be identified in 61 patients, and out of all identified serotypes 31/83 (37%) were non-PCV13 serotypes. Conclusions The occurrence of any bacteria or any viruses at high levels was associated with severe pneumonia at admission. Children with congenital disorders might need a higher attention when having symptoms of acute respiratory infection, as developed pneumonia could lead to fatal outcome.

- 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.
