Rehabilitation Practices Delivered by Physical and Occupational Therapists to Brazilian Children With Congenital Zika Syndrome: A Cross-Sectional Study.

Congenital Zika syndrome (CZS) is a health condition that has affected the development of thousands of children in Brazil. Because it is a new condition, its understanding is an ongoing process. Therefore, it is important to know the rehabilitation interventions being delivered to improve the functioning of these children. We aimed to describe the practices of physical therapists (PTs) and occupational therapists (OTs) who provide follow-up care for children with CZS in Brazil. This cross-sectional study included PTs and OTs who assist children with CZS in Brazil. An online questionnaire was used to verify the participants' personal characteristics and professional work environment, as well as the rehabilitation programs they implemented in Brazil for children with CZS. Data were analyzed using descriptive statistics. A total of 116 professionals (79 PT and 37 OT) who work mainly in public health services (81.9%) participated in the study. Of these, 24.1% plan interventions based on reading scientific articles, 66.4% did not report using the biopsychosocial model, 52.6% do not perform any assessments before starting an intervention, 31.9% use neurodevelopmental treatment, and 22.4% use sensorimotor stimulation interventions. The majority of the interventions are delivered 1 to 2 times a week, lasting up to 1 hour. Professional training and knowledge translation strategies are needed to implement evidence-based practices and improve the quality of rehabilitation programs for Brazilian children with CZS.

Causes of death in children with congenital Zika syndrome in Brazil, 2015 to 2018: A nationwide record linkage study.

Children with congenital Zika syndrome (CZS) have severe damage to the peripheral and central nervous system (CNS), greatly increasing the risk of death. However, there is no information on the sequence of the underlying, intermediate, immediate, and contributing causes of deaths among these children. The aims of this study are describe the sequence of events leading to death of children with CZS up to 36 months of age and their probability of dying from a given cause, 2015 to 2018. In a population-based study, we linked administrative data on live births, deaths, and cases of children with CZS from the SINASC (Live Birth Information System), the SIM (Mortality Information System), and the RESP (Public Health Event Records), respectively. Confirmed and probable cases of CZS were those that met the criteria established by the Brazilian Ministry of Health. The information on causes of death was collected from death certificates (DCs) using the World Health Organization (WHO) DC template. We estimated proportional mortality (PM%) among children with CZS and among children with non-Zika CNS congenital anomalies (CA) by 36 months of age and proportional mortality ratio by cause (PMRc). A total of 403 children with confirmed and probable CZS who died up to 36 months of age were included in the study; 81.9% were younger than 12 months of age. Multiple congenital malformations not classified elsewhere, and septicemia unspecified, with 18 (PM = 4.5%) and 17 (PM = 4.2%) deaths, respectively, were the most attested underlying causes of death. Unspecified septicemia (29 deaths and PM = 11.2%) and newborn respiratory failure (40 deaths and PM = 12.1%) were, respectively, the predominant intermediate and immediate causes of death. Fetuses and newborns affected by the mother's infectious and parasitic diseases, unspecified cerebral palsy, and unspecified severe protein-caloric malnutrition were the underlying causes with the greatest probability of death in children with CZS (PMRc from 10.0 to 17.0) when compared to the group born with non-Zika CNS anomalies. Among the intermediate and immediate causes of death, pneumonitis due to food or vomiting and unspecified seizures (PMRc = 9.5, each) and unspecified bronchopneumonia (PMRc = 5.0) were notable. As contributing causes, fetus and newborn affected by the mother's infectious and parasitic diseases (PMRc = 7.3), unspecified cerebral palsy, and newborn seizures (PMRc = 4.5, each) were more likely to lead to death in children with CZS than in the comparison group. The main limitations of this study were the use of a secondary database without additional clinical information and potential misclassification of cases and controls. The sequence of causes and circumstances involved in the deaths of the children with CZS highlights the greater vulnerability of these children to infectious and respiratory conditions compared to children with abnormalities of the CNS not related to Zika.

Out-of-pocket expenditures associated with congenital zika syndrome in Brazil: an analysis of household health spending

Objective: The study aims to estimate catastrophic health expenditures associated with the diagnosis and follow-up treatment of Congenital Zika Syndrome (CZS) in children affected during the 2015-2016 epidemic in Brazil. Catastrophic health expenditures are defined as health spending that exceeds a predefined proportion of the household’s total expenditures, exposing family members to financial vulnerability. Methods: Ninety-six interviews were held in the cities of Fortaleza and Rio de Janeiro in a convenience sample, using a questionnaire on sociodemographic characteristics and private household expenditures associated with the syndrome, which also allowed estimating catastrophic expenditures resulting from care for CZS. Results: Most of the mothers interviewed in the study were brown, under 34 years of age, unemployed, and reported a monthly family income of two minimum wages or less. Spending on medicines accounted for 77.6% of the medical expenditures, while transportation and food were the main components of nonmedical expenditures, accounting for 79% of this total. The affected households were largely low-income and suffered catastrophic expenditures due to the disease. Considering the family income metric, in 41.7% of the households, expenses with the child’s disease exceeded 10% of the household income. Conclusion: Public policies should consider the financial and healthcare needs of these families to ensure adequate support for individuals affected by CZS.

Estimating the cost of congenital Zika syndrome to families and healthcare providers in Rio de Janeiro and Pernambuco, Brazil: results of a case-control study

Background: Children with congenital Zika syndrome (CZS) have a wide range of additional healthcare needs. This study aimed to estimate the direct costs of CZS from the health provider and family perspectives, and the indirect costs for families, in two Brazilian states: Rio de Janeiro and Pernambuco. Methods: A case-control study was undertaken between May 2017-January 2018 recruiting 174 cases with severe CZS, 41 with mild/moderate CZS and 269 children with no CZS, across the two sites, from existing studies. The primary caregiver was interviewed using a structured questionnaire to collect information on healthcare use and costs incurred during the previous 12 months. In Rio de Janeiro, health care utilization data was also extracted from electronic medical records. We estimated direct and indirect costs incurred as a result of CZS from the perspective of the health system and families. Results: Children with CZS accessed more healthcare facilities and reported longer travel and waiting times than children unaffected by CZS. Total costs from the health provider perspective of outpatient visits, were highest for children with severe CZS (U$1,411) followed by children with mild/moderate CZS (U$264) and children without CZS (U$107). This pattern was apparent for direct costs incurred by families, while median indirect costs were low. Families of children with CZS reported high levels of catastrophic expenditures; Expenses incurred by families to meet their child’s needs as a proportion of household income was 30% (IQR=14%-67%, p<0.01) for children with severe CZS, 11% (IQR=4%-33%, p<0.01) for mild/moderate CZS, and 1% (IQR=0%-8%) for controls. Costs incurred by families were generally higher in Rio de Janeiro than Pernambuco. Conclusions: Families of children affected by CZS in Brazil may need additional public health resources and social benefits to protect them from incurring catastrophic expenses while meeting the needs of their children.

Juntos: A Support Program for Families Impacted by Congenital Zika Syndrome in Brazil.

The 2015-2016 Zika virus outbreak in Brazil was unprecedented and resulted in the birth of more than 3,000 children with congenital Zika syndrome (CZS). These children experience multiple complex health conditions and have limited services to support them and their family's needs. An existing family support program for children with cerebral palsy (Getting to Know Cerebral Palsy) was adapted to the Zika context in Brazil through expert consultation. The program was pilot tested at 2 sites among 6 groups of caregivers (total of 48 families) from August 2017 to June 2018. Group observation and focus group discussions with facilitators and participants at the end of each session informed fast-track learning, which was used to tailor the program for future groups. Fast-track learning-adjusting the intervention in real time based on gathered feedback-was found to be a helpful process to inform and hone the program from its initial concept. The intervention, Juntos, is a facilitated participatory group program for caregivers of children who have CZS. The group sessions are cofacilitated by a parent of a child who has CZS and an allied health professional. The group meets for 10 sessions that last 4 hours. Each session includes an icebreaker, activities, and group discussions. Content covers practical information on caring for a child with a developmental disability including that caused by Zika. Psychosocial support forms an important component, and families are guided from the first week to define and develop their own communities of support. Six pilot groups were successfully run in Rio de Janeiro and Greater Salvador, Bahia. The groups gave positive feedback on acceptability and demand. The program has the potential to be an important tool for community health and social support services in South America in response to Zika. The program can also be applied to children with neurodevelopmental disabilities other than those caused by the Zika virus, which could be important in ensuring families of children with CZS are less isolated.

"Life Is Taking Me Where I Need to Go": Biographical Disruption and New Arrangements in the Lives of Female Family Carers of Children with Congenital Zika Syndrome in Pernambuco, Brazil.

The congenital Zika syndrome (CZS) epidemic in Brazil turned the spotlight on many other factors beyond illness, such as poverty, gender, and inequalities in health care. Women were the emblematic subjects in this study, not only because Zika virus is a vertical transmission disease, but also because women—in Brazil and elsewhere—typically represent the primary carers of children. This is a qualitative analytic study using semi-structured interviews with 23 female family carers of children with CZS in Brazil. Through the concept of biographical disruption, we analysed some of the social impacts experienced by women involved in caring for affected children. We identified that the arrival of a child with disabilities resulted in biographical disruption similar to that experienced by people with chronic illnesses. Social support networks were configured through an alliance between women from different generations, revealing solidarity networks, but also highlighting the absence of the state in tackling these social vulnerabilities. Tracing the pathways of these biographical narratives enables us to understand how women have acted to defend the value of their disabled children in a society structured on the model of body normativity and inequality. These results may provide clues to a more inclusive society, which confronts systems of gender oppression and the sexual division of labour focused on women.

Go Zika Go: A Feasibility Protocol of a Modified Ride-on Car Intervention for Children with Congenital Zika Syndrome in Brazil.

Children with congenital Zika syndrome (CZS) present severe motor disability and can benefit from early powered mobility. The Go Zika Go project uses modified ride-on toy cars, which may advance the body functions, activities, and participation of children. This paper describes the study protocol aiming to assess the feasibility of a modified ride-on car intervention for children with CZS in Brazil. A mixed-methods design with a multiple 1-week baseline, 3-month intervention, and 1-month follow-up will be implemented. Modified ride-on car training sessions will be conducted three times a week at the participants’ home or in the clinic. The primary outcome will be a narrative description of study feasibility (photovoice method, focus groups, parent feasibility questionnaire and assessment of learning powered mobility). Secondary outcomes will be switch activation, driving sessions journal, social-cognitive interactions, mobility (pediatric evaluation of disability inventory computer adaptive test), goal attainment scaling (GAS), and participation (young children’s participation and environment measure). Go Zika Go is expected to be viable and to improve function, activity, and participation of children with CZS, providing a low-cost, evidence-based rehabilitation option that will be relevant to early child development in a global perspective.

Developmental Outcomes Among Young Children With Congenital Zika Syndrome in Brazil

Although birth defects in children with congenital Zika syndrome (CZS) are expected to result in significant intellectual disabilities, the extent of delay and profiles of development have yet to be fully described. To describe the neurodevelopmental profiles of children with CZS and to test whether prenatal and postpartum characteristics were associated with the severity of developmental delays. This is a case series of the trajectories of developmental, behavioral, and medical needs of 121 young children with CZS who were assessed at a specialized rehabilitation center in Recife, Brazil, beginning in January 2018 as part of 5-year longitudinal study. Children were included if they had serologic confirmation of Zika virus and met clinical criteria accompanied by parental report of suspected exposure to Zika virus during pregnancy. Prenatal Zika virus exposure. The Brazilian version of the Bayley Scales of Infant and Toddler Development, Third Edition, was administered by trained assessors as part of an initial comprehensive assessment battery. Caregiver interviews and medical record reviews were conducted to gather basic demographic information and medical comorbidities. Linear regression was used to identify potential factors for development. The sample included 121 young children (mean [SD] age, 31.2 [1.9] months; 61 [50.4%] girls). At age approximately 2.5 years, nearly all children in this sample demonstrated profound developmental delays across all domains of functioning, with a mean (SD) developmental age equivalent to approximately 2 to 4 months (eg, cognitive domain, 2.24 [3.09] months; fine motor subscale, 2.15 [2.93] months; expressive language subscale, 2.30 [2.52] months). A relative strength was found in receptive language, with scores on this scale significantly higher than most other domains (eg, cognition: t = 3.73; P < .001; fine motor: t = 6.99; P < .001). Head circumference at birth was the single strongest factor associated with outcomes across all developmental domains (eg, cognitive: β = 1.41; SE, 0.67; P = .04; fine motor: β = 1.36; SE, 0.49; P = .007). The findings of this study provide important information regarding the severity of disability that these children and their families will experience. The findings also establish an initial point from which to monitor developmental trajectories, medical comorbidities (eg, seizures), effectiveness of interventions, and cumulative consequences on families.

Congenital Zika Syndrome-Assessing the Need for a Family Support Programme in Brazil.

The Zika outbreak in Brazil caused congenital impairments and developmental delays, or Congenital Zika Syndrome (CZS). We sought to ascertain whether a family support programme was needed and, if so, could be adapted from the Getting to Know Cerebral Palsy programme (GTKCP) designed for children with cerebral palsy (CP). We conducted a systematic review of the needs of families of children with CZS or CP in low- and middle-income countries and reviewed the findings of the Social and Economic Impact of Zika study. We undertook a scoping visit to three facilities offering services to children with CZS in Brazil to understand potential utility and adaptability of GTKCP. The literature review showed that caregivers of children with CZS experience challenges in mental health, healthcare access, and quality of life, consistent with the CP literature. The scoping visits demonstrated that most support provided to families was medically orientated and while informal support networks were established, these lacked structure. Caregivers and practitioners expressed an eagerness for more structure community-based family support programmes. A support programme for families of children with CZS in Brazil appeared relevant and needed, and may fill an important gap in the Zika response.

Anxiety and depression among caregivers of young children with Congenital Zika Syndrome in Brazil

Purpose To examine the psychological well-being of primary caregivers of infants and toddlers with Congenital Zika Syndrome (CZS), and the roles of family resources, parenting stress, and coping strategies in caregivers’ adaptation. Materials and methods Family caregivers (N = 50) of children with CZS who were receiving treatment at a rehabilitation hospital in Recife, Brazil participated a cross-sectional survey study. Caregivers completed measures of anxiety and depression, coping strategies, family resources, and parenting stress. Results Mild to severe symptoms of depression were identified in 40% of caregivers and were a more prominent concern than symptoms of anxiety. Fewer family resources and high levels of parenting stress were significantly associated with both anxiety and depression. The association between parenting stress and depression was moderated by coping, such that parenting stress was associated with higher caregiver depression at low but not high levels of coping strategy use. Conclusions Practitioners in Brazil should consider the role of family coping and resources as important resilience promoting factors in the development of new programs designed to promote psychological adaptation in caregivers to children with CZS. It is recommended that caregiver mental health support services be integrated into existing early intervention programs targeting children with CZS. Implications for Rehabilitation Parents and other primary caregivers are encouraged to take an active role in the care and developmental monitoring of children born with CZS, but their ability to provide care may be compromised by difficulties in psychological adaptation. Moderate and severe symptoms of depression were more prominent in caregivers than moderate and severe symptoms of anxiety (20% versus 6%, respectively). Practitioners should include assessment of coping strategies, parenting stress and family resources conjointly with evaluation of symptoms of depression and anxiety as part of routine CZS family evaluations. A useful approach for caregivers in Brazil may be to more fully integrate caregiver mental health support services into existing early intervention programs for children with CZS.

1674. Orthopedic Complications of Congenital Zika Syndrome in Brazil

BackgroundCongenital Zika Syndrome (CZS) has a broad spectrum of clinical presentations that are still being described. This cohort study aimed to describe the orthopedic complications in children with microcephaly (MCP) related to Zika virus (ZIKV).MethodsWe evaluated 36 children with CZS up to 17 months of age followed at a pediatric rehabilitation center in the northeast of Brazil. Cohort enrollment occurred with children born between January 2015 and May 2016. We assessed their social profiles and orthopedic findings.ResultsOf the 36 cases, 25 were male. All of them lived in rural area. 25 had at least one congenital orthopedic alteration. Hip subluxation was the most common problem detected (n = 15); other lower limb abnormalities included knee subluxation (n = 7), clubfoot (n = 7); congenital vertical talus (n = 4); plano-valgus foot (n = 5). In relation to the upper limbs, 11 children presented with some shoulder and/or elbow abnormality and 16 had some alteration in the hand and/or on the wrist.ConclusionOrthopedic problems appear to be common in children with CZS and should be a focus of larger clinical studies. An initial orthopedic assessment may provide a better quality of life by helping children avoid further complications/deformities. Our results emphasize the orthopedic problems associated with CZS and the need to better describe many complications in the natural history of this infection.Disclosures All authors: No reported disclosures.

The association of depression, anxiety, and stress with caring for a child with Congenital Zika Syndrome in Brazil; Results of a cross-sectional study.

BackgroundZika virus (ZIKV) infection in pregnancy can cause microcephaly and a wide spectrum of severe adverse outcomes, collectively called “Congenital Zika Syndrome” (CZS). Parenting a child with disabilities can have adverse mental health impacts, but these associations have not been fully explored in the context of CZS in Brazil.Methodology/Principal findingsA cross-sectional study was undertaken in Recife and Rio de Janeiro, including 163 caregivers of a child with CZS (cases) and 324 caregivers with an unaffected child (comparison subjects), identified from existing studies. The primary caregiver, almost always the mother, was interviewed using a structured questionnaire to collect information on: depression, anxiety, and stress (Depression, Anxiety, and Stress Scale—DASS-21), social support (Medical Outcomes Study Social Support Scale—MOS-SSS), and socio-demographic data. Data was collected May 2017-January 2018. Ethical standards were adhered to throughout the research. A high proportion of mothers reported experiencing severe or extremely severe levels of depression (18%), anxiety (27%) and stress (36%). Mothers of children with CZS were more likely to experience symptoms of depression, anxiety andstress, compared to mothers of comparison children. These associations were more apparent among mothers living in Rio de Janeiro. These differences were reduced after adjustment for socio-economic status and social support. Among mothers of children with CZS, low social support was linked to higher levels of depression, anxiety and stress, but there was no association with socio-economic status.Conclusions/SignificanceDepression, anxiety and stress were very common among mothers of young children in Brazil, regardless of whether they were parenting a child with disabilities. Mothers of children with CZS may be particularly vulnerable to poor mental health, and this association may be buffered through better social support.

Social and economic impacts of congenital Zika syndrome in Brazil: Study protocol and rationale for a mixed-methods study.

Global concern broke out in late 2015 as thousands of children in Brazil were born with microcephaly, which was quickly linked to congenital infection with Zika virus (ZIKV). ZIKV is now known to cause a wider spectrum of severe adverse outcomes-congenital Zika syndrome (CZS)-and also milder impairments. This study aimed to explore the social and economic impacts of CZS in Brazil. Data was collected through mixed methods across two settings: Recife City and Jaboatão dos Guararapes in Pernambuco State (the epicentre of the epidemic), and the city of Rio de Janeiro (where reports of ZIKV infection and CZS were less frequent). Data was collected May 2017-January 2018. Ethical standards were adhered to throughout the research. In-depth qualitative interviews were conducted with: mothers and other carers of children with CZS (approximately 30 per setting), pregnant women (10-12 per setting), men and women of child-bearing age (16-20 per setting), and health professionals (10-12 per setting). Thematic analysis was undertaken independently by researchers from at least two research settings, and these were shared for feedback. A case-control study was undertaken to quantitatively explore social and economic differences between caregivers of a child with CZS (cases) and caregivers with an unaffected child (controls). We aimed to recruit 100 cases and 100 controls per setting, from existing studies. The primary caregiver, usually the mother, was interviewed using a structured questionnaire to collect information on: depression, anxiety, stress, social support, family quality of life, health care and social service use, and costs incurred by families. Multivariable logistic regression analyses were used to compare outcomes for cases and controls. Costs incurred as a result of CZS were estimated from the perspective of the health system, families and society. Modelling was undertaken to estimate the total economic burden of CZS from those three perspectives.

Development and assessment of the feasibility of a Zika family support programme: a study protocol

The Zika virus outbreak in Brazil in 2015 affected thousands of people. Zika is now known to cause congenital malformations leading to impairments and developmental delays in affected children, including Congenital Zika Syndrome (CZS). Children with CZS have complex care needs. Caregivers require significant levels of support to meet these needs, and there are large gaps in healthcare services. This study aims to develop, pilot and assess the feasibility and scalability of a community-based Family Support Programme for caregivers of children with CZS. The programme is adapted from the Getting to Know Cerebral Palsy (GTKCP) programme for the context of CZS in Brazil. GTKCP is a 10-session programme held with 6-10 caregivers in the local community. It includes practical, educational, peer-support and psychosocial aspects, which aim to improve confidence and capacity to care for a child with CP, and quality of life and empowerment of caregivers. The research project contains four components: Ascertaining need for the caregiver programme: a mixed-methods approach that included two literature reviews, interviews with key stakeholders in country, and incorporation of findings from the Social and Economic Impact of Zika study.Adapting GTKCP for the context of CZS and Brazil: undertaken with guidance from technical experts.Pilot testing the intervention: deliver the 10-session programme to one group of caregivers of children with CZS in Rio de Janeiro and another in Greater Salvador.Update the manual through fast-track learning from participant and facilitator feedback. Assessing the feasibility of the intervention for scale up: deliver the updated programme to two groups each in Rio de Janeiro and Greater Salvador, and evaluate the acceptability, demand, implementation, practicality, adaptation, integration, expansion, and limited efficacy, through questionnaires, direct observation, semi-structured interviews and cost calculation. The project has ethics approval in both the UK and Brazil.

Association of Severe Hydrocephalus With Congenital Zika Syndrome

Hydrocephalus is a treatable but potentially fatal complication that has not been previously described in congenital Zika syndrome (CZS). To describe the clinical features and imaging findings in 24 patients with congenital Zika syndrome (CZS) who developed hydrocephalus. This case series included patients with hydrocephalus who were born in October and November 2015 and followed up until mid-2017 in the 2 largest national referral centers for CZS in Brazil. The participants included consecutively enrolled children with a clinical and laboratorial diagnosis of CZS who developed clinical and/or image findings suggestive of hydrocephalus and who were confirmed to experience increased intracranial hypertension during ventriculoperitoneal shunt procedures. To retrospectively describe clinical and image findings in these 24 patients. This multicenter cohort included 308 patients with CZS; 24 consecutive children were enrolled in this study. These children were aged between 3 to 18 months, and 13 of 24 (54%) were female. All patients presented with at least 1 positive test result for anti-Zika antibodies in cerebrospinal fluid or serum and had classic signs of CZS. At the time of hydrocephalus diagnosis, only 14 of 24 patients (58%) had symptoms and signs suggestive of hydrocephalus (mainly worsening seizures, vomiting, irritability, and/or sudden increase of head circumference percentile). Two of 24 patients (8%) had no symptoms suggestive of hydrocephalus but were found to have reduced brain volume on repeated imaging. Cerebellar or brainstem hypoplasia on baseline imaging were found in 18 of 23 patients (78%). At the second computed tomographic scan, all patients showed a marked increase of ventricular volume, compatible with communicating hydrocephalus, and reduction of brain tissue that was visibly worse than on baseline imaging for the 23 patients with repeated scans. We present evidence that hydrocephalus is a complication of CZS in at least a proportion of patients. The clinical spectrum of this condition continues to evolve, but given that presenting signs and symptoms of hydrocephalus can be challenging to recognize in CZS, we provisionally recommend that high suspicion and appropriate monitoring for hydrocephalus should be part of the standard care of patients with CZS.
