RESUMEN
The inadequate dietary diversity of pregnant women in low- and middle-income countries, including Rwanda, is rising and leading to macro and micronutrient deficiencies. The extent of dietary diversity and the factors contributing to it are unknown in Rwanda. This cross-sectional study, with 612 women who attended antenatal care services in Rwanda's Southern Province, identified determinants of dietary diversity among pregnant women. A multistage sampling scheme was used in which four districts were sampled, thereafter one urban and one rural health centre was sampled in each district and finally, a systematic sample of pregnant women was selected in each sampled health centre. Dietary diversity was measured using Minimum Dietary Diversity for Women (MDD-W), and multiple logistic regression models were fitted to identify factors associated with dietary diversity. Only 44.1% (95% confidence interval (CI) of [40.1%, 48.0%]) of participants had adequate dietary diversity. Approximately 95.4% of participants consumed grains, white roots, and tubers. The food groups that were the least consumed consisted of eggs (n = 99, 16.4%), as well as those consisting of milk and milk products (n = 112, 18.5%). The factors which were positively associated with dietary diversity were owning a radio (adjusted odds ratio [aOR] = 1.90 [95% CI 1.27, 2.85]), maternal education (aOR = 1.85 [95% CI 1.28, 2.65]), having a kitchen garden (aOR = 1.69 [95% CI 1.11, 2.57]) and nutrition knowledge score (aOR = 1.45 [95% CI 1.21, 1.74]) for a five-point increase in nutrition knowledge score. The factors negatively associated with dietary diversity include food insecurity, which reduced the odds of dietary diversity (aOR = 0.19 [0.07, 0.50]) per five-unit increase in food insecurity. Furthermore, the odds of adequate dietary diversity were lower among urban residents than rural residents (aOR = 0.69 [0.47, 1.03]). The household size was associated with dietary diversity with the odds of dietary diversity decreasing by 12% for a five-unit increase in household size (aOR = 0.88 [0.79; 0.99]). 23% had poor nutritional status, indicated by their mid-upper arm circumference (MUAC; < 23 cm). Enhanced nutritional education is needed to improve the nutritional knowledge of this population with particular emphasis on the consumption of animal-source foods. Sensitisation activities promoting ownership of kitchen gardens and radios could improve dietary diversity among Rwanda's pregnant women.

BACKGROUND: COVID-19 vaccination rates in South Africa remain low at 51% of the adult population being fully vaccinated, defined as having two shorts of the COVID-19 vaccine with or without a booster. To improve vaccine uptake, a community-based intervention was tested in a high vaccine hesitancy community in South Africa. Trained community youths used social media, face to face interactions, door to door and neighbourhood outreach activities to deliver the intervention. METHODS: To assess if the intervention had an impact, data was collected before the intervention and after the intervention in two districts, Wentworth an intervention site and Newlands East a control site. Both districts are in KwaZulu Natal Province, South Africa. The following outcomes, changes on perceptions and knowledge about COVID-19, intention to get vaccinated for those who were not fully vaccinated and vaccination uptake were assessed using difference-in-difference methods applied through Augmented Inverse-Probability Weighting and contrasts of Potential Outcome Means (POM). RESULTS: One thousand, one hundred and fifty (1 150) participants agreed to take part in the study at baseline, and 916 (80%) were followed up after the 9-week intervention period. Intention to get vaccinated for COVID-19 was higher (difference-in-difference, DID 20%, 95% CI 6% - 35% higher), more people were fully vaccinated (DID 10%, 95% CI 0% - 20%) or partially vaccinated (DID 16%, 95% CI 6% - 26%) in Wentworth the intervention site compared to Newlands East, the control site. There were noticeable increases on the percentage of study participants indicating trust on the Government's COVID 19 programme, from 24% at baseline to 48% after the intervention in the intervention group than in the control group, 26% baseline and 29% at follow-up. There was a 10% (absolute) increase on the percentage of participants' saying they believed health care workers provided reliable information, 58% at baseline and 68% at follow-up in the intervention group, but there was little change in the control group 56% and 57% for baseline and follow-up respectively. CONCLUSION: The youth-led intervention implemented in Wentworth, a community with a high rate of vaccine hesitancy, was effective in increasing vaccination uptake. Given the low COVID-19 vaccine coverage in South Africa and across the African region, as well as the new emerging variant of concern (XBB 1.5), there is an urgent need to scale up such intervention at the community level to address persistent misinformation and promote vaccine equality.

Despite the expanding digitisation of individual health data, informed consent for the collection and use of health data is seldom explicitly sought in public sector clinics in South Africa. This study aims to identify perceptions of informed consent practices for health data capture, access, and use in Gauteng and the Western Cape provinces of South Africa. Data collection from September to December 2021 included in-depth interviews with healthcare providers (n = 12) and women (n = 62) attending maternity services. Study findings suggest that most patients were not aware that their data were being used for purposes beyond the individualised provision of medical care. Understanding the concept of anonymised use of electronic health data was at times challenging for patients who understood their data in the limited context of paper-based folders and booklets. When asked about preferences for electronic data, patients overwhelmingly were in favour of digitisation. They viewed electronic access to their health data as facilitating rapid and continuous access to health information. Patients were additionally asked about preferences, including delivery of health information, onward health data use, and recontacting. Understanding of these use cases varied and was often challenging to convey to participants who understood their health data in the context of information inputted into their paper folders. Future systems need to be established to collect informed consent for onward health data use. In light of perceived ties to the care received, these systems need to ensure that patient preferences do not impede the content nor quality of care received.

The increasing digitisation of personal health data has led to an increase in the demand for onward health data. This study sought to develop local language scripts for use in public sector maternity clinics to capture informed consent for onward health data use. The script considered five possible health data uses: 1. Sending of general health information content via mobile phones; 2. Delivery of personalised health information via mobile phones; 3. Use of women's anonymised health data; 4. Use of child's anonymised health data; and 5. Use of data for recontact. Qualitative interviews (n = 54) were conducted among women attending maternity services in three public health facilities in Gauteng and Western Cape, South Africa. Using cognitive interviewing techniques, interviews sought to:(1) explore understanding of the consent script in five South African languages, (2) assess women's understanding of what they were consenting to, and (3) improve the consent script. Multiple rounds of interviews were conducted, each followed by revisions to the consent script, until saturation was reached, and no additional cognitive failures identified. Cognitive failures were a result of: (1) words and phrases that did not translate easily in some languages, (2) cognitive mismatches that arose as a result of different world views and contexts, (3) linguistic gaps, and (4) asymmetrical power relations that influence how consent is understood and interpreted. Study activities resulted in the development of an informed consent script for onward health data use in five South African languages for use in maternity clinics.
In the wake of growing digitisation of personal health data, greater scrutiny is needed on the language of informed consent and the processes for soliciting consent in health care facilities. Qualitative interviews using cognitive interviewing techniques were used to develop and refine consent language in English, Sesotho, isiXhosa, isiZulu and Setswana for the onward use of health data among maternity clients in public sector primary health clinics in the Western Cape and Gauteng provinces of South Africa. We found that translation in local languages and addressing individual words and phrases was only one barrier to requesting informed consent. Other barriers were cognitive mismatches between the question intent and how women understood the question, linguistic gaps that were linked to language and identity, and power dynamics that affected how women understood the consent script. Emerging language scripts used "/" to present words in multiple languages; a reflection of the multi-linguistic nature of communities in this context.

South Africa launched a mass COVID-19 vaccination campaign in May 2021, targeting 40 million adults. Understanding predictors of COVID-19 vaccine intentions was required to achieve this goal. We conducted a population-based survey in June-July 2021 using the WHO Behavioral and Social Drivers (BeSD) of COVID-19 Vaccination tool to determine predictors of vaccine hesitancy, defined as intention to refuse or uncertainty whether to accept COVID-19 vaccination. There were 1193 participants, mean age 39 (standard deviation 15) years, and 53% women, of whom 58% trusted information provided by healthcare workers and 32% were vaccine hesitant. Independent predictors of vaccine hesitancy included concerns about side effects (odds ratio (OR) 11.41; 95% confidence interval (CI) 3.5-50.80), lack of access to the online vaccine registration platform (OR 4.75; CI 2.15-10.37), distrust of government (OR 3.0; CI 1.33-6.77), belief in conspiracy theories (OR 3.01; CI 1.32-6.77), having no monthly income (OR 1.84; CI 1.12-3.07), and depending on someone else to make vaccination decision (OR 2.47; CI 1.06-5.77). We identified modifiable predictors of vaccine hesitancy at the start of South Africa's COVID-19 vaccination rollout. These factors should be addressed by different stakeholders involved in the national immunization program through tailored communication and other effective strategies that increase vaccine literacy, reach low-income households, and engender confidence in government.
RESUMEN
Background: The South African development goals for young women aged 15 to 24 are to reduce HIV incidence, teenage pregnancy and gender-based violence, and to increase school completion and economic security. Early, unintended pregnancy undermines these goals, creating discourses of early motherhood that position young women as powerless. There has been scant attention on the agency of young women in their structural context.Objective: This study explored how young women exercise agency after an unintended pregnancy and make decisions concerning their future, including sexual and reproductive health, school completion and/or income generation, and caregiving for their babies.Methods: I used narrative analysis to explore the lived experiences of young mothers, paying attention to decision-making during pregnancy and motherhood. Domains of analysis included health care, education, and caregiving. I conducted in-depth interviews with 30 young mothers: 30 were interviewed once, nine were interviewed twice, and six were interviewed three times. I interviewed four significant people in the lives of young mothers and six health care providers at a health centre.Results: Progressive policy facilitates increased access to services for young pregnant and parenting women. However, education and health care providers continue to discriminate against them, formally through denying them access to services and informally through discourses of shame which pervade their structural context. Kinship capital in urban and rural contexts and the Child Support Grant mitigate some struggles in early motherhood and help young mothers navigate decision-making.Conclusion: Young mothers exercise agency along a continuum to realise their aspirations. Social and structural support mediate their agency. Policy needs to expand the focus from prevention to include issues of care and support after an early, unintended pregnancy to ensure the health and wellbeing of young mothers and their children.

In South Africa, sexual and reproductive health services aim to facilitate access to and utilisation of care to young people. We draw on narrative interviews with 45 young mothers and six health care providers delivering sexual and reproductive health services at an urban health centre, to understand how young mothers experienced services in relation to ante- and post-natal care, including termination services. Although health care providers emphasised what they considered young women's 'ignorance' and 'irresponsibility' as central to early and unintended pregnancy; they also expressed their sympathy and concern. In a resource-limited health care setting, with health system inefficiencies and lack of specialised training, there was little opportunity to deliver high-quality care to young women. We draw attention to the need to prioritise the training of health care providers to expand early pregnancy testing and termination services and to deliver patient-centred family planning services to young women.

One of the key pro-inflammatory mediators activated by amyloid protein in neurodegenerative disorders of the brain, such as Alzheimer's disease is the complement system. Vaccinia virus complement control protein secreted by vaccinia virus, commonly known as VCP, was found to inhibit amyloid protein mediated up-regulation of complement system in vitro. In the current research investigation, VCP was administered twice (First dose at 3 weeks and the second dose at 6-7 months) intracranially into the parietal cortical area of Mo/Hu APPswe transgenic mice. At the age of 2 years or more, the same mice were subjected to cued-learning, spatial learning, probe and reverse probe trial paradigms of cheese board maze tasks for cognitive assessment. A significant difference was observed between VCP treated mice and the transgenic controls on days two and three of the cued trials and probe trials. The VCP treated group showed a similar trend as revealed during the spatial learning trial and reverse probe trial. A differential pattern of thioflavine S staining was observed in the VCP treated group. These results suggest that administration of VCP at an early age in transgenic mice may be effective in regulating the progression to the familial form of Alzheimer's disease at a later age.

Vaccinia virus complement control protein (VCP) inhibits both the classical and alternate complement pathways. In diseases such as traumatic brain injury (TBI) and Alzheimer's disease (AD), pathological inflammation is caused by amongst several factors, prolonged or inappropriate activation of the complement system and is a significant cause of neurodegeneration. This study investigates for the first time the use of a cheeseboard maze to evaluate cognitive deficits and the effect of VCP on memory processes in 2- and 3-month-old mice that express mutant amyloid precursor protein (APPswe) and mutant presenilin 1 (Ps1dE9) that correspond to a form of early onset AD. A four-phase training schedule was carried out on the cheeseboard maze before intracranial injections of 5 microl of VCP (1.7 microg/microl) or 5 microl saline. Two weeks later the effect of VCP on memory was evaluated. A statistically significant decrease in goal latency in VCP-treated mice than saline-treated transgenic mice in both the first probe and reverse tasks was observed. Similarly, after a second intracranial VCP or saline injection performed 2 months later, the 6.5- and 7.5-month aged VCP-injected mice performed significantly better in goal latency in both second probe and reverse tasks than saline-treated mice. These data also demonstrated that the use of a dry maze is a sensitive technique for distinguishing cognitive measures between non-transgenic and APPswe/PS1De9 transgenic mice at a much earlier stage.

Anxiety disorders are the most common of the psychiatric disorders and are also associated with significant economic costs and impaired work productivity. The first-line pharmacotherapy of pharmatherapy for a number of anxiety disorders comprises selective serotonin re-uptake inhibitors (SSRIs) and serotonin and noradrenaline re-uptake inhibitors (SNRIs). Benzodiazepines are still widely used for the treatment of several anxiety disorders. Although these agents are effective, many patients are treatment-refractory and more effective, better tolerated medications are required. This paper discusses the understandings of mechanisms involved in the anxiety disorders and reviews emerging medications. Mechanisms underlying the use of d-cycloserine, second generation antipsychotics and beta-blockers are particularly exciting.

Vaccinia virus complement control protein (VCP) is an immunomodulator that inhibits both the classical and alternate pathways of the complement system, therefore preventing cell death and inflammation. VCP has previously been shown to be therapeutically effective in mild and moderate traumatic brain injury models. In this study the efficacy of VCP in a severe head injury model is investigated in Wistar rats. Training in a Morris Water Maze (MWM) commenced 2 days prior stereotaxic surgery. Rats were anesthetized before being subjected to a severe (2.7-3.0 atm) lateral fluid percussion injury (FPI) 3.0 mm lateral to the sagittal suture and 4.5 mm posterior to bregma. Ten microliters of VCP (1.7 microg/microl) was injected into the injury site immediately after FPI. Fourteen days post-FPI, rats were tested for spatial learning and memory using the Morris Water Maze, followed by a battery of sensorimotor tests. The latter tests showed statistically significant differences between saline-treated and VCP-treated rats in lateral left pulsion (p=0.001) and tactile placing (p=0.002) on the first 5 days of testing. In addition, significant differences in right lateral pulsion in the first 4 days (p=0.007) of testing was evident. The results suggest that in a severe head injury model, VCP at this dosage favorably influences sensorimotor outcome.

Previous studies have shown that traumatic mild brain injury in a rat model is accompanied by breakdown of the blood brain barrier and the accumulation of inflammatory cells. A therapeutic agent, vaccinia virus complement control protein (VCP), inhibits both the classic and the alternative pathways of the complement system and, in so doing, prevents cell death and inflammation. With the use of a rat mild injury model, the effects of VCP on spatial learning and memory were tested. Training in a Morris water maze consisted of a total of 16 trials over a 2-day period before rats were anesthetized and subjected to mild (1.0-1.1 atm) lateral fluid percussion injury (FPI) 3.0 mm lateral to the sagittal suture and 4.5 mm posterior to bregma. Ten microl of VCP (1.7 mg/ml) was injected into the injury site immediately after FPI. Two weeks post-FPI the rats were assessed in the Morris water maze for spatial learning and memory. Neurologic motor function tests were carried out after FPI for 14 consecutive days and again after 28 days. The Morris water maze data show that FPI plus saline-injected rats spent a significantly (P <0.05) larger amount of time in one of the incorrect quadrants than did the FPI plus VCP-injected group. Neurologic evaluations 24 hours postinjury revealed differences in sensorimotor function between groups. The results suggest that in a mild injury model, VCP influences neurologic outcome and offers some enhancement in spatial memory and learning.

Alzheimer's disease (AD) is a common cause of dementia, resulting from accumulated beta-amyloid protein deposits in the brain. As the population ages the incidence of AD is also on the rise. The incidence is very high in the developed countries where life expectancy is high, but it is also rising rapidly in the developing countries. Caring for patients suffering from AD is a major economic burden. The mechanisms underlying the neuropathology of AD are slowly being unravelled. Here we explore the many models and theories, which have been proposed over the years. We then discuss a potential therapeutic agent, vaccinia virus complement control protein (VCP), involved in modulating the complement system in AD. VCP has been shown in in vitro studies to block the complement activation caused by the beta peptide. Traumatic injuries to the brain are well known risk factors associated with the development of AD. VCP can also enhance functional recovery resulting from traumatic brain injury and may be able to slow the progression of traumatic brain injury to AD. Here we describe strategies for testing this hypothesis and evaluating other agents such as VCP.
