A one health approach to strengthening antimicrobial stewardship in Wakiso District, Uganda
Antimicrobial stewardship (AMS), as one of the global strategies to promote responsible use of antimicrobials to prevent antimicrobial resistance (AMR), remains poor in many low-and middle-income countries (LMICs). We implemented a project aimed at strengthening AMS in Wakiso district, Uganda using a One Health approach. A total of 86 health practitioners (HPs), including animal health workers, and 227 community health workers (CHWs) participated in training workshops, and over 300 pupils from primary schools were sensitized on AMR, AMS, and infection prevention and control (IPC). We further established two multidisciplinary online communities of practice (CoPs) for health professionals and students, with a current membership of 321 and 162, respectively. In addition, a Medicine and Therapeutics Committee (MTC) was set up at Entebbe Regional Referral Hospital. The project evaluation, conducted three months after training, revealed that the majority of the HPs (92.2%) and CHWs (90.3%) reported enhanced practices, including improved hand washing (57.3% and 81.0%, respectively). In addition, 51.5% of the HPs reported a reduction in the quantity of unnecessary antibiotics given per patient. This project demonstrates that AMS interventions using a One Health approach can promote understanding of the prudent use of antimicrobials and improve practices at health facilities and in communities
Caregiver socioemotional health as a determinant of child wellâ being in schoolâ aged and adolescent Ugandan children with and without perinatal HIV exposure
ObjectiveCaregiver socioâ emotional attributes are major determinants of child wellâ being. This investigation in vulnerable schoolâ aged Ugandan children estimates relationships between children’s wellâ being and their caregiver’s anxiety, depression and social support.MethodsPerinatally HIVâ infected, HIVâ exposed uninfected and HIVâ unexposed Ugandan children and their caregivers were enrolled. Perinatal HIV status was determined by 18 months of age using DNAâ polymerase chainâ reaction test; status was confirmed via HIV rapid diagnostic test when children were 6â 18 years old. Five indicators of child wellâ being (distress, hopelessness, positive future orientation, esteem and quality of life (QOL)) and caregiversâ socioemotional status (depressive symptoms, anxiety and social support) were measured using validated, culturally adapted and translated instruments. Categories based on tertiles of each caregiver psychosocial indicator were defined. Linear regression analyses estimated percent differences (β) and corresponding 95% confidence intervals (CI) for child wellâ being in relation to caregiver’s psychosocial status.ResultsAs per tertile increment, caregiver anxiety was associated with 2.7% higher distress (95%CI:0.2%, 5.3%) and lower selfâ esteem/QOL (β = â 1.3%/â 2.6%; 95%CI: â 5.0%,â 0.2%) in their children. Child distress/hopelessness increased (β = 3.3%/7.6%; 95%CI:0.4%, 14.7%) and selfâ esteem/QOL decreased 2.3% (β = â 2.3%/â 4.4%; 95%CI: â 7.2%, â 1.3%) as per tertile increment in caregiver depression. Higher caregiver social support was associated with lower distress and higher positive outlook (β = 3%; 95%CI:1.4%, 4.5%) in their children. HIVâ infected/exposed children had most caregiver depressionâ related QOL deficit (β = â 5.2%/â 6.8%; 95%CI: â 12.4%, â 0.2%) and HIVâ unexposed children had most caregiver social supportâ related enhancements in positive outlook (β=4.5%; 95%CI:1.9%, 7.1%).ConclusionsCaregiver anxiety, depressive symptoms and low social support were associated with worse wellâ being in schoolâ aged and adolescent children. Improvement of caregiver mental health and strengthening caregiver social support systems may be a viable strategy for improving wellâ being of vulnerable children and adolescents in this setting.ObjectifLes attributs socioâ affectifs des responsables d’enfants sont des déterminants majeurs du bienâ être des enfants. Cette investigation menée auprès d’enfants ougandais vulnérables dâ âge scolaire a estimé les relations entre le bienâ être des enfants et l’anxiété, la dépression et le soutien social de leur responsable.MéthodesDes enfants ougandais infectés par le VIH de manière périnatale, exposés au VIH mais non infectés, et non exposés au VIH ainsi que leurs responsables ont été inscrits. Le statut VIH périnatal a été déterminé à lâ âge de 18 mois à l’aide du test de PCR de lâ ADN; le statut a été confirmé par un test de diagnostic rapide du VIH chez les enfants âgés de 6 à 18 ans. Cinq indicateurs du bienâ être de l’enfant (détresse, désespoir, orientation future positive, estime et qualité de vie (QV)), et le statut psychosocial des responsables (symptômes dépressifs, anxiété et soutien social) ont été mesurés à l’aide de méthodes validées, adaptées à la culture et respectées et d’outils traduits. Des catégories basées sur les tertiles de chaque indicateur psychosocial du responsable ont été définies. Des analyses de régression linéaire ont estimé les différences en pourcentage (β) et les intervalles de confiance (IC) à 95% correspondants pour le bienâ être de l’enfant par rapport au statut psychosocial de leurs responsables.RésultatsPar incrément de tertile, l’anxiété des responsables était associé à 2,7% de détresse plus élevé (IC95%: 0,2%, 5,3%) et de faible estime de soi/QV (β = â 1,3%/â 2,6%; IC95%: â 5,0%, â 0,2%) chez leurs enfants. La détresse et le désespoir des enfants augmentaient (β = 3,3%/7,6%; IC95%: 0,4%, 14,7%) et l’estime de soi/QV diminuait de 2,3% (β = â 2,3%/â 4,4%; IC95%: â 7,2%, â 1,3%) par incrément de tertile de la dépression chez le responsable. Un soutien social plus élevé des responsables était associé à une détresse moindre et à une perspective positive plus élevée (β = 3%; IC95%: 1,4%, 4,5%) chez leurs enfants. Les enfants infectés/exposés au VIH présentaient pour la plupart un déficit de QV lié à la dépression de leurs responsables (β = â 5,2%/â 6,8%; IC95%: â 12,4%, â 0,2%), et ceux non exposés au VIH présentaient pour la plupart des améliorations en perspective positive liées au soutien social de leurs responsables (β = 4,5%; IC95%: 1,9%, 7,1%).ConclusionsL’anxiété, les symptômes dépressifs et un faible soutien social du responsable étaient associés à un bienâ être précaire chez les enfants dâ âge scolaire et les adolescents. L’amélioration de la santé mentale des responsables et le renforcement des systèmes de soutien social pour les responsables peuvent constituer une stratégie viable pour améliorer le bienâ être des enfants et des adolescents vulnérables dans cette région.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/149358/1/tmi13221.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/149358/2/tmi13221_am.pd
Using electronic medical records to understand the impact of SARS-CoV-2 lockdown measures on maternal and neonatal outcomes in Kampala, Uganda.
Kawempe National Referral Hospital (KNRH) is a tertiary facility with over 21,000 pregnant or postpartum women admitted annually. The hospital, located in Kampala, Uganda, uses an Electronic Medical Records (EMR) system to capture patient data. Used since 2017, this readily available electronic health record (EHR) has the benefit of informing real-time clinical care, especially during pandemics such as COVID-19. We investigated the use of EHR to assess risk factors for adverse pregnancy and infant outcomes that can be incorporated into a data visualization dashboard for real time decision making during pandemics. This study analysed data from the UgandaEMR collected at pre-, during- and post-lockdown timepoints of the COVID-19 pandemic to determine its use in monitoring risk factors for adverse pregnancy and neonatal outcomes. Logistic regression models were used to identify the risk factors for adverse pregnancy and maternal outcomes including prematurity, obstetric complications, still births and neonatal deaths. Pearson chi-square test was used for pair-wise comparison of the outcomes at the various stages of the pandemic. Data analysis was performed in R, within the International COVID-19 Data Alliance (ICODA) workbench. A visualisation dashboard was developed based on the risk factors, to support decision making and improved healthcare delivery. Comparison of pre-and post-lockdown variables showed an increased risk of pre-term birth (adjusted Odds Ratio (aOR = 1.67, 95% confidence interval (CI) 1.38-2.01)); obstetric complications (aOR = 2.77, 95% CI: 2.53-3.03); immediate neonatal death (aOR = 3.89, 95% CI 2.65-5.72) and Caesarean section (aOR = 1.22, 95% CI 1.11-1.34). The significant risk factors for adverse outcomes were younger maternal age and gestational age <32weeks at labour. This study demonstrates the feasibility of using EHR to identify and monitor at-risk subpopulation groups accessing health services in real time. This information is critical for the development of timely and appropriate interventions in outbreaks and pandemic situations

Seroepidemiology of SARS-CoV-2 in a cohort of pregnant women and their infants in Uganda and Malawi.
BACKGROUND: Data on SARS-CoV-2 infection in pregnancy and infancy has accumulated throughout the course of the pandemic, though evidence regarding asymptomatic SARS-CoV-2 infection and adverse birth outcomes are scarce. Limited information is available from countries in sub-Saharan Africa (SSA). The pregnant woman and infant COVID in Africa study (PeriCOVID Africa) is a South-South-North partnership involving hospitals and health centres in five countries: Malawi, Uganda, Mozambique, The Gambia, and Kenya. The study leveraged data from three ongoing prospective cohort studies: Preparing for Group B Streptococcal Vaccines (GBS PREPARE), SARS-CoV-2 infection and COVID-19 in women and their infants in Kampala and Mukono (COMAC) and Pregnancy Care Integrating Translational Science Everywhere (PRECISE). In this paper we describe the seroepidemiology of SARS-CoV-2 infection in pregnant women enrolled in sites in Uganda and Malawi, and the impact of SARS-CoV-2 infection on pregnancy and infant outcomes. OUTCOME: Seroprevalence of SARS-CoV-2 antibodies in maternal blood, reported as the proportion of seropositive women by study site and wave of COVID-19 within each country. METHODS: The PeriCOVID study was a prospective mother-infant cohort study that recruited pregnant women at any gestation antenatally or on the day of delivery. Maternal and cord blood samples were tested for SARS-CoV-2 antibodies using Wantai and Euroimmune ELISA. In periCOVID Uganda and Malawi nose and throat swabs for SARS-Cov-2 RT-PCR were obtained. RESULTS: In total, 1379 women were enrolled, giving birth to 1387 infants. Overall, 63% of pregnant women had a SARS-CoV-2 positive serology. Over subsequent waves (delta and omicron), in the absence of vaccination, seropositivity rose from 20% to over 80%. The placental transfer GMR was 1.7, indicating active placental transfer of anti-spike IgG. There was no association between SARS-CoV-2 antibody positivity and adverse pregnancy or infancy outcomes
Induction of humoral immune response to multiple recombinant Rhipicephalus appendiculatus antigens and their effect on tick feeding success and pathogen transmission
BACKGROUND: Rhipicephalus appendiculatus is the primary vector of Theileria parva, the etiological agent of East Coast fever (ECF), a devastating disease of cattle in sub-Saharan Africa. We hypothesized that a vaccine targeting tick proteins that are involved in attachment and feeding might affect feeding success and possibly reduce tick-borne transmission of T. parva. Here we report the evaluation of a multivalent vaccine cocktail of tick antigens for their ability to reduce R. appendiculatus feeding success and possibly reduce tick-transmission of T. parva in a natural host-tick-parasite challenge model.
METHODS: Cattle were inoculated with a multivalent antigen cocktail containing recombinant tick protective antigen subolesin as well as two additional R. appendiculatus saliva antigens: the cement protein TRP64, and three different histamine binding proteins. The cocktail also contained the T. parva sporozoite antigen p67C. The effect of vaccination on the feeding success of nymphal and adult R. appendiculatus ticks was evaluated together with the effect on transmission of T. parva using a tick challenge model.
RESULTS: To our knowledge, this is the first evaluation of the anti-tick effects of these antigens in the natural host-tick-parasite combination. In spite of evidence of strong immune responses to all of the antigens in the cocktail, vaccination with this combination of tick and parasite antigens did not appear to effect tick feeding success or reduce transmission of T. parva.
CONCLUSION: The results of this study highlight the importance of early evaluation of anti-tick vaccine candidates in biologically relevant challenge systems using the natural tick-host-parasite combination

Knowledge, perceptions and practices on antimicrobial resistance in humans and animals in Wakiso district, Uganda: a cross sectional study
Despite increasing evidence on antimicrobial resistance (AMR), there is limited literature on antimicrobial access and use in humans and animals in community settings globally. This study assessed knowledge and perceptions of AMR, as well as practices relating to the use of antimicrobials in humans and animals in Wakiso district, Uganda. This was a cross-sectional study among 418 participants that employed quantitative data collection methods. A structured questionnaire that included questions on knowledge, perceptions, practices related to AMR, and perceptions on access to antimicrobials in humans and animals was used. Data was analysed in STATA version 10. The majority of participants 63.6% (266/418) had heard about AMR mainly from family and friends 57.5% (153/266), and most 70.8% (296/418) were aware that resistant microorganisms cause infections that are difficult to treat. Most participants 62.7% (262/418) thought that they should complete the full dose of antimicrobials when on treatment. However, on the last occasion of antimicrobial use, 13.0% (44/338) revealed that they did not complete the full course of treatment. Participants who were single (APR = 1.12, C.I = 1.03–1.12, p-value = 0.01) and earning between 91 and 290 USD on average per month (APR = 1.12, C.I = 1.02–1.23, p-value = 0.02) were more likely to have completed a given antimicrobial course as compared to those who were married/cohabiting and earned less than 15 USD respectively. The majority of participants 60% (251/418) owned animals, and 81.3% (204/251) reported using antimicrobials mainly for prevention 61.3% (125/204) or treatment of sick animals 70.6% (144/204). Among the participants, 57.4% (117/204) reported not having sold or consumed animal products within a week after exposure to antimicrobials. Interventions to prevent AMR should adopt a One Health approach to address the gap in knowledge and practices relating to the use of antimicrobials in humans and animals

Scaling-up interventions for strengthening antimicrobial stewardship using a one health approach in Wakiso District, Uganda
We implemented a multidisciplinary project between Uganda and the UK aimed at strengthening antimicrobial stewardship (AMS) in Wakiso district, with a focus on capacity building, stakeholder engagement, and knowledge exchange using a One Health approach. Project activities included: trainings and workshops on antimicrobial resistance (AMR), AMS, infection prevention and control (IPC); Global Point Prevalence Survey (GPPS) data collection and analysis; and the mentorship of lower level health facilities. Our project demonstrated that AMS interventions using a One Health approach can enhance understanding of the prudent use of antimicrobials and improve practices at health facilities and within communities
Indirect effects of COVID-19 on maternal, neonatal, child, sexual and reproductive health services in Kampala, Uganda.
BACKGROUND: COVID-19 impacted global maternal, neonatal and child health outcomes. We hypothesised that the early, strict lockdown that restricted individuals' movements in Uganda limited access to services. METHODS: An observational study, using routinely collected data from Electronic Medical Records, was carried out, in Kawempe district, Kampala. An interrupted time series analysis assessed the impact on maternal, neonatal, child, sexual and reproductive health services from July 2019 to December 2020. Descriptive statistics summarised the main outcomes before (July 2019-March 2020), during (April 2020-June 2020) and after the national lockdown (July 2020-December 2020). RESULTS: Between 1 July 2019 and 31 December 2020, there were 14 401 antenatal clinic, 33 499 deliveries, 111 658 childhood service and 57 174 sexual health attendances. All antenatal and vaccination services ceased in lockdown for 4 weeks.During the 3-month lockdown, the number of antenatal attendances significantly decreased and remain below pre-COVID levels (370 fewer/month). Attendances for prevention of mother-to-child transmission of HIV dropped then stabilised. Increases during lockdown and immediately postlockdown included the number of women treated for high blood pressure, eclampsia and pre-eclampsia (218 more/month), adverse pregnancy outcomes (stillbirths, low-birth-weight and premature infant births), the rate of neonatal unit admissions, neonatal deaths and abortions. Maternal mortality remained stable. Immunisation clinic attendance declined while neonatal death rate rose (from 39 to 49/1000 livebirths). The number of children treated for pneumonia, diarrhoea and malaria decreased during lockdown. CONCLUSION: The Ugandan response to COVID-19 negatively impacted maternal, child and neonatal health, with an increase seen in pregnancy complications and fetal and infant outcomes, likely due to delayed care-seeking behaviour. Decreased vaccination clinic attendance leaves a cohort of infants unprotected, affecting all vaccine-preventable diseases. Future pandemic responses must consider impacts of movement restrictions and access to preventative services to protect maternal and child health

Access, use and disposal of antimicrobials among humans and animals in Wakiso district, Uganda: a qualitative study
Background: Inappropriate use of antimicrobials in both humans and animals is a key driver of antimicrobial resistance (AMR). In addition, human behaviours such as poor disposal of antimicrobials in the environment can increase their exposure to microbes which can impact on humans and animals. However, evidence on access, use and disposal of antimicrobials for humans and animals at community level in Uganda is limited. This study therefore explored access, use and disposal of antimicrobials among humans and animals in Wakiso district, Uganda.
Methods: A qualitative study was conducted that involved focus group discussions (FGDs) and key informant interviews (KIIs). Participants of the FGDs were community health workers (CHWs) and farmers involved in animal husbandry, while key informants included: officials from the Ministry of Health; Ministry of Agriculture, Animal Industry and Fisheries; human and animal health professionals; district health officials; and members of the national AMR surveillance committee. Twelve FGDs were held (8 for CHWs and 4 for farmers) while 15 KIIs were conducted. Thematic analysis in NVivo (version 12) was performed.
Results: Five main themes emerged from the study: access to antimicrobials in humans; access to antimicrobials in animals; use of antimicrobials in humans; use of antimicrobials in animals; and disposal of antimicrobials. Community members mainly accessed antimicrobials for humans from public health facilities such as government health centres, as well as private facilities, including drug shops and clinics. Antimicrobials for animals were obtained from veterinary practitioners and drug shops (both for humans and veterinary). Examples of inappropriate use of antimicrobials in both humans and animals was evident, such as sharing antibiotics among household members, and giving human-prescribed antimicrobials to food-producing animals as growth promoters. While some CHWs returned unused antimicrobials to public health facilities for proper disposal, community members mainly disposed of antimicrobials with general household waste including dumping in rubbish pits.
Conclusions: There is a need to increase awareness among the population on proper access, use and disposal of antimicrobials for both humans and animals. Development of a drug disposal system at community level would facilitate improved waste management of antimicrobials. Together, these measures would help prevent the rate of progression of AMR in communities
