Global and regional child deaths due to injuries: an assessment of the evidence

Thermal-activated Polydopamine bilayer film exhibits dual-mode synergistic antibacterial properties for enhanced salmon preservation

Foodborne pathogens threaten food safety and human health, prompting the need for innovative preservation solutions. Polydopamine endowed with photothermal properties represents a novel material for the inhibition of foodborne pathogens. This study develops a bilayer antibacterial film using polydopamine-berberine nanoparticles (PDA-BBR), leveraging dual-mode synergistic antibacterial effects through chemical and photothermal mechanisms. The film, incorporating starch and polylactic acid layers, was prepared via solvent casting and characterized for mechanical properties, water vapor permeability (WVP), and antibacterial efficacy. The results revealed that the 2.0 % PDA-BBR film achieved a tensile strength of 4.00 MPa, a WVP of 2.30 × 10-11 g/m·s·Pa, and over 95 % inhibition against Escherichia coli and Staphylococcus aureus. Moreover, the film preserved salmon quality by maintaining texture, lowering total volatile basic nitrogen to 16.19 mg/100 g, and inhibiting spoilage during 9 days of storage at 4 °C. These findings highlight PDA-BBR film as a promising food preservation approach with enhanced antibacterial and preservation performance.

Trends in fatal paediatric unintentional injury: what is going on?

In recent years, the reduction in rates of fatal unintentional injuries to children in the USA has not only plateaued, beginning before the pandemic, but has reversed, with increases across most mechanisms of injury. This study seeks to understand the reasons for this trend, focusing on unintentional injuries to children aged 1-14 years in 2001-2023 and on injuries with the highest fatality rates and with the most substantial increases in the last few years.The highest rate of fatalities and most substantial changes were due to motor vehicle crashes, drowning, fires and burns. Many factors that are associated with the risk of injury fatality actually decreased in prevalence over the last decade while the fatality rates were plateauing and then increasing. These include improved motor vehicle and highway and roadway safety designs, lower rates of cigarette smoking, more homes with carbon monoxide alarms, fewer mobile homes, higher life-jacket use, fewer small recreational boats and decreases in child poverty. Increases in emotional and behavioural disorders are not likely responsible for changes in unintentional injury fatalities in this age group. An important contributor to injury, particularly among the racial groups experiencing the greatest change in the mortality trajectory, is the sociocultural economic environment in which children live, learn and play. Smartphone use by teens and caregivers was the one risk factor which dramatically increased over the last decade, and distraction from mobile phone use stands out as likely the greatest culprit in this increase in fatalities.

Application of an integrated behaviour-change model on grandparental adherence towards childhood domestic injury prevention in Hong Kong: a longitudinal study

Background/purpose

Every year, unintentional injury claims thousands of children's lives and causes disabilities in many more. For very young children, these injuries often occur at home. The risks of domestic injury can be reduced through proper implementation of injury preventive measures. In this study, we investigated the motivational and belief processes underlying childhood domestic injury prevention in grandparent caregivers based on the integrated model of self-determination theory and theory of planned behaviour.

Method

Grandparents (n=299, mean age=62.61 years, SD=5.91, men=20.07%) of 0-2-year-old infants and toddlers self-reported their perceived psychological need support, autonomous motivation, perceived behavioural control (PBC), subjective norms, attitude, intention and adherence with regard to domestic injury prevention for their children at two time points (T1: baseline, T2: 4-month follow-up).

Results/outcomes

Data were analysed with structural equation modelling, and the proposed model yielded an acceptable fit with the data: χ2=905.09 (df=531), Comparative Fit Index=0.94, Tucker-Lewis Index=0.93, root mean square error of approximation=0.05 and standardised root mean square residual=0.078. Our results supported our hypothesis, demonstrating significant and positive associations between the following key constructs: (1) psychological need support from family and autonomous motivation; (2) autonomous motivation and social-cognitive beliefs; (3) social-cognitive beliefs and intentions; and (4) intention and behavioural adherence. Subjective norms and PBC, but not attitudes, were also found to significantly mediate the indirect effects of psychological need support and autonomous motivation on intention and behavioural adherence.

Conclusions

Overall, the integrated model seems to be a feasible framework for explaining grandparents' domestic injury prevention behaviour.

Management of Pediatric Superficial Partial-Thickness Burns with Polyhexamethylene Biguanide: Outcomes and Influencing Factors

Background: In burn care, achieving swift healing with minimal complications remains paramount. This investigation assesses the role of polyhexamethylene biguanide (PHMB) in managing pediatric superficial partial-thickness burns, focusing on the effects of various patient-specific factors on recovery. Methods: Through a retrospective analysis of 27 pediatric cases treated with PHMB, we evaluated the impact of age, burn size, dressing frequency, treatment delay, cold therapy application, and analgesic usage on the time until reepithelialization (TTRE). Results: The majority of patients benefited from early cold therapy, yet only 1 in 3 patients received analgesics. A mean healing time of 8.78 (SD: 2.64) days was observed, with the extent of the burn showing a strong correlation (r: 0.63) to TTRE. Most treatments were managed outpatient, evidenced by a negligible average hospital stay (0.96 days), with recorded no complications. Conclusions: Our findings endorse PHMB as a promising treatment for superficial second-degree burns in young patients, due to the observed stable and rapid wound closure without the association of increased risks. Continued exploration into the optimal application of prehospital interventions and the comprehensive benefits of PHMB in pediatric burn management is necessary. Future research should assess long-term outcomes, including functionality, scar quality, and patient satisfaction.

Prognostic Significance of Nuclear Factor Kappa B (p65) among Breast Cancer Patients in Cape Coast Teaching Hospital

Breast cancer is the most prevalent cancer among African women, with high mortality rates in Ghana. Nuclear factor kappa B (NF-kB) has been associated with tumor progression in breast cancer. However, its clinical validation is controversial and understudied with no known published data on NF-kB (p65) among breast cancer patients in Ghana and other African countries. This study assessed the prognostic significance of NF-kB (p65) expression and its association with various clinicopathological features in breast cancer patients. Ninety formalin-fixed breast cancer tissues and 15 normal breast tissues were used to determine the expression of NF-kB (p65) using immunohistochemistry. We explored the correlation between expression of NF-kB (p65) and clinicopathological features. NF-kB (p65) was expressed in 86.7% of breast cancer tissues. There was a significant relationship between NF-kB (p65) expression and tumor grade, proliferation index (Ki67), and molecular subtype. High NF-kB (p65) expression in tumor grade 3 was about 10 times that of grade 1 (54.2% vs. 5.1%), and Ki67 > 20 was 79.7% compared to 20.3% for Ki67 ≤ 20. Patients with triple-negative breast cancer (TNBC) had 49.1% overexpression of NF-kB (p65) compared to 17%, 25.4%, and 8.5% for luminal A, luminal B, and HER2 cases, respectively. This study demonstrates that NF-kB (p65) was highly expressed among breast cancer patients at Cape Coast Teaching Hospital, Ghana, especially in TNBC. NF-kB (p65) could serve as a biomarker for cancer stage, progression, prognosis and as a therapeutic target.

Domestic Accidents of Children in the Orodara District of Burkina Faso: Mothers' Knowledge of First-Aid Practices

First-aid practices after a domestic accident are not always known, especially in Africa. This study aimed to measure mothers' knowledge of emergency procedures and attitudes in the event of domestic accidents in children. We conducted a cross-sectional study in the Orodara health district, Kénédougou province, Burkina Faso, among mothers of children aged 0-14 years. The dependent variable was the mothers' knowledge of domestic accident first-aid practices, and the independent variables were the sociodemographic characteristics of the households and the mothers. Determinants were identified using linear regression with a threshold of 5%. A total of 798 mothers were surveyed. The mean knowledge score was 6.9 (standard deviation = 1.5) out of 19. Upon our multivariate analysis, the factors associated with the mothers' knowledge about first-aid practices were the mothers' age, the number of children under 14 years old living in the same household, the household size, the score for knowledge of non-recommended attitudes, the mothers' level of education, and the place of residence. This study showed that awareness campaigns, especially in rural areas, seem important in improving mothers' knowledge of first-aid practices in domestic accidents and, therefore, reducing the morbidity and mortality associated with domestic accidents.

Child injuries in Lebanon: assessing mothers' injury prevention knowledge attitude and practices

BACKGROUND

Childhood injury is a neglected public health problem with a sizeable burden on children's well-being and their families. This study aims to describe the pattern and types of childhood injuries and to determine the level of mothers' Knowledge, Attitude, and Practices (KAP) towards childhood injury prevention in Lebanon. The study further examines the association between childhood injury occurrence and mothers' supervision.

METHODS

This cross-sectional study recruited mothers of children aged up to 10 years from multiple sites (i.e., a medical center, a private clinic, a healthcare facility, and a refugee camp clinic). Data were collected on mothers' KAP toward childhood injuries using self-administrated questionnaires. A summation score for KAP correct answers was calculated and descriptive and statistical analyses were performed to measure the association between the outcomes.

RESULTS

A total of 264 mothers were surveyed and injury data were collected on their 464 children. The prevalence of childhood injury was 20% in the past 12 months, mostly sustained by males (53.8%) and children aged 5-10 years (38.7%). The most common type of injury was fall (48.4%), followed by burns (%7.5), and sports injuries (7.5%). Hospitalized children were more likely to be males and older than 5 years (p < 0.001). More than one-third of the mothers demonstrated poor knowledge, while the majority showed poor practice (54.4%), and fair attitude (45.6%) towards child injury prevention. Children of working mothers have three times higher odds of sustaining injuries (OR: 2.95, 95% CI: 1.60;5.47) compared to those of non-working mothers, accounting for possible confounders (p = 0.001).

CONCLUSION

Childhood injuries represent a major health problem in Lebanon. Findings from this study showed that mothers are less knowledgeable and unprepared to prevent their children from getting injured. Educational programs are much needed to address the gap in the mothers' KAP toward child injury prevention. Further studies are recommended to understand the cultural context and examine its key determinants to identify effective strategies and develop tailored interventions for preventing childhood injuries.

What is the impact of national public expenditure and its allocation on neonatal and child mortality? A machine learning analysis

BACKGROUND

Understanding the impact of national public expenditure and its allocation on child mortality may help governments move towards target 3.2 proposed in the 2030 Agenda. The objective of this study was to estimate the impacts of governmental expenditures, total, on health, and on other sectors, on neonatal mortality and mortality of children aged between 28 days and five years.

METHODS

This study has an ecological design with a population of 147 countries, with data between 2012 and 2019. Two steps were used: first, the Generalized Propensity Score of public spending was calculated; afterward, the Generalized Propensity Score was used to estimate the expenditures' association with mortality rates. The primary outcomes were neonatal mortality rates (NeoRt) and mortality rates in children between 28 days and 5 years (NeoU5Rt).

RESULTS

The 1% variation in Int$ Purchasing Power Parity (Int$ PPP) per capita in total public expenditures, expenditure in health, and in other sectors were associated with a variation of -0.635 (95% CI -1.176, -0.095), -2.17 (95% CI -3.051, -1.289) -0.632 (95% CI -1.169, -0.095) in NeoRt, respectively The same variation in public expenditures in sectors other than health, was associates with a variation of -1.772 (95% CI -6.219, -1.459) on NeoU5Rt. The results regarding the impact of total and health public spending on NeoU5Rt were not consistent.

CONCLUSION

Public investments impact mortality in children under 5 years of age. Likely, the allocation of expenditures between the health sector and the other social sectors will have different impacts on mortality between the NeoRt and the NeoU5Rt.

The trend of unintentional injury-related mortality among children aged under-five years in China, 2010-2020: a retrospective analysis from a national surveillance system

BACKGROUND

In this study, we estimated the trend of unintentional injury mortality among children aged under-five years in China during 2010-2020.

METHODS

Data were obtained from China's Under 5 Child Mortality Surveillance System (U5CMSS). The total unintentional injury mortality and all specific-causes unintentional injury mortality was calculated, annual numbers of deaths and live births were adjusted by a 3-year moving average under-reporting rate. The Poisson regression model and the Cochran-Mantel-Haenszel method were used to calculate the average annual decline rate (AADR) and the adjusted relative risk (aRR) of the unintentional injury mortality.

RESULTS

In 2010-2020, a total of 7,925 unintentional injury-related deaths were reported in U5CMSS, accounting for 18.7% of all reported deaths. The overall proportion of unintentional injury-related deaths to total under-five children deaths has increased from 15.2% to 2010 to 23.8% in 2020 (χ2 = 227.0, p < 0.001), the unintentional injury mortality significantly decreased from 249.3 deaths per 100,000 live births in 2010 to 178.8 deaths per 100,000 live births in 2020, with an AADR 3.7% (95%CI 3.1-4.4). The unintentional injury mortality rate decreased from 2010 to 2020 in both urban (from 68.1 to 59.7 per 100,000 live births) and rural (from 323.1 to 230.0 per 100,000 live births) areas (urban: χ2 = 3.1, p < 0.08; rural: χ2 = 113.5, p < 0.001). The annual rates of decline in rural areas and urban areas were 4.2% (95%CI 3.4-4.9) and 1.5% (95%CI 0.1-3.3), respectively. The leading causes of unintentional injury mortality were suffocation (2,611, 32.9%), drowning (2,398, 30.3%), and traffic injury (1,428, 12.8%) in 2010-2020. The cause-specific of unintentional injury mortality rates decreased with varying AADRs in 2010-2020, except for traffic injury. The composition of unintentional injury-related deaths also varied by age group. Suffocation was the leading cause in infants, drowning and traffic injury were the leading causes in children aged 1-4 years. Suffocation and poisoning has high incidence in October to March and drowning has high in June to August.

CONCLUSION

The unintentional injury mortality rate of children aged under-five years decreased significantly from 2010 to 2020 in China, but great inequity exists in unintentional injury mortality in urban and rural areas. Unintentional injuries are still an important public health problem affecting the health of Chinese children. Effective strategies should be strengthened to reduce unintentional injury in children and these policies and programmes should be targeted to more specific populations, such as rural areas and males.

Unintentional injury deaths among children under five in Hunan Province, China, 2015-2020

Injury is the most common cause of preventable morbidity and death among children under five. This study aimed to describe the epidemiological characteristics of injury-related mortality rates in children under five and to provide evidence for future preventive strategies. Data were obtained from the Under Five Child Mortality Surveillance System in Hunan Province, China, 2015-2020. Injury-related mortality rates with 95% confidence intervals (CI) were calculated by year, residence, gender, age, and major injury subtype (drowning, suffocation, traffic injuries, falls, and poisoning). And crude odds ratios (ORs) were calculated to examine the association of epidemiological characteristics with injury-related deaths. The Under Five Child Mortality Surveillance System registered 4,286,087 live births, and a total of 22,686 under-five deaths occurred, including 7586 (which accounted for 33.44% of all under-five deaths) injury-related deaths. The injury-related under-five mortality rate was 1.77‰ (95% CI 1.73-1.81). Injury-related deaths were mainly attributed to drowning (2962 cases, 39.05%), suffocation (2300 cases, 30.32%), traffic injuries (1200 cases, 15.82%), falls (627 cases, 8.27%), and poisoning (156 cases, 2.06%). The mortality rates due to drowning, suffocation, traffic injuries, falls, and poisoning were 0.69‰ (95% CI 0.67,0.72), 0.54‰ (95% CI 0.51,0.56), 0.28‰ (95% CI 0.26,0.30), 0.15‰ (95% CI 0.13,0.16), and 0.04‰ (95% CI 0.03,0.04), respectively. From 2015 and 2020, the injury-related mortality rates were 1.78‰, 1.77‰, 1.60‰, 1.78‰, 1.80‰, and 1.98‰, respectively, and showed an upward trend (χ²_trend = 7.08, P = 0.01). The injury-related mortality rates were lower in children aged 0-11 months than in those aged 12-59 months (0.52‰ vs. 1.25‰, OR = 0.41, 95% CI 0.39-0.44), lower in urban than rural areas (1.57‰ vs. 1.88‰, OR = 0.84, 95% CI 0.80-0.88), and higher in males than females (2.05‰ vs . 1.45‰, OR = 1.42, 95% CI 1.35-1.49). The number of injury-related deaths decreased with children's age. Injury-related deaths happened more frequently in cold weather (around February). Almost half (49.79%) of injury-related deaths occurred at home. Most (69.01%) children did not receive treatment after suffering an injury until they died, and most (60.98%) injury-related deaths did not receive treatment because it was too late to get to the hospital. The injury-related mortality rate was relatively high, and we have described its epidemiological characteristics. Several mechanisms have been proposed to explain these phenomena. Our study is of great significance for under-five child injury intervention programs to reduce injury-related deaths.

Injury in Children with Developmental Disorders: A 1:1 Nested Case-Control Study Using Multiple Datasets in Taiwan

Although past studies have identified predictors related to child injuries with developmental disorders, national-level research in Asia is limited. The objective of this study was to explore the risk factors for child injuries with developmental disorders in Taiwan using a national-level integrated database for the period between 2004-2015 (The Maternal and Child Health Database, National Health Insurance Research Database, Census Registry, and Indigenous Household Registration). Children younger than 12 years old who had records of visiting the ER or being hospitalized due to injury or without injury were included in this study. A 1:1 nested case-control study (injury vs. noninjury) to examine the risk factors for child injury with developmental disorder was performed. A total of 2,167,930 children were enrolled. The risk factors were associated with repeated ER visits or hospitalization: being indigenous (adjusted odds ratio [AOR]: 1.51; CI: 1.45-1.57); having a developmental disorder (AOR: 1.74; CI: 1.70-1.78); and having parents with illicit drug use (AOR: 1.48; CI: 1.32-1.66), alcohol abuse (AOR: 1.21; CI: 1.07-1.37), or a history of mental illness (AOR: 1.43; CI: 1.41-1.46). Being indigenous, having developmental disorders, and having parents with history of illicit drug use, alcohol abuse, or mental illness were predictors related to injuries in children.

Pediatric trauma burden in Tanzania: analysis of prospective registry data from thirteen health facilities

Background

Trauma is among the leading causes of morbidity and mortality among pediatric and adolescent populations worldwide, with over ninety percent of childhood injuries occurring in low-income and middle-income countries. Lack of region-specific data on pediatric injuries is among the major challenges limiting the ability of health systems to implement interventions to prevent injuries and improve outcomes. We aim to characterize the burden of pediatric health injuries, initial healthcare interventions and outcomes seen in thirteen diverse healthcare facilities in Tanzania.

Methods

This was a prospective cohort study of children aged up to 18 years presenting to emergency units (EUs) of thirteen multi-level health facilities in Tanzania from 1^st October 2019 to 30^th September 2020. We describe injury patterns, mechanisms and early interventions performed at the emergency units of these health facilities.

Results

Among 18,553 trauma patients seen in all thirteen-health facilities, 4368 (23.5%) were children, of whom 2894 (66.7%) were male. The overall median age was 8 years (Interquartile range 4–12 years). Fall 1592 (36.5%) and road traffic crash (RTC) 840 (19.2%) were the top mechanisms of injury. Most patients 3748 (85.8%) arrived at EU directly from the injury site, using motorized (two or three) wheeled vehicles 2401 (55%). At EU, 651 (14.9%) were triaged as an emergency category. Multiple superficial injuries (14.4%), fracture of forearm (11.7%) and open wounds (11.1%) were the top EU diagnoses, while 223 (5.2%) had intracranial injuries. Children aged 0–4 years had the highest proportion (16.3%) of burn injuries. Being referred and being triaged as an emergency category were associated with high likelihood of serious injuries with adjusted odds ratio (AOR) 4.18 (95%CI 3.07–5.68) and 2.11 (95%CI 1.75–2.56), respectively. 1095 (25.1%) of patients were admitted to inpatient care, 14 (0.3%) taken to operation theatre, and 25 (0.6%) died in the EU.

Conclusions

In these multilevel health facilities in Tanzania, pediatric injuries accounted for nearly one-quarter of all injuries. Over half of injuries occurred at home. Fall from height was the leading mechanism of injury, followed by RTC. Most patients sustained fractures of extremities. Future studies of pediatric injuries should focus on evaluating various preventive strategies that can be instituted at home to reduce the incidence and associated impact of such injuries.

Circumstances and Consequences of Violence-Related Injuries Presenting at Hospital. A Study at the Pediatric Emergency and Forensic Medicine Units of Maputo Central Hospital, Mozambique

Rates of violence against children are high in Sub-Saharan Africa and information is scarce on the resulting injuries. This study investigates sex-related differences in the circumstances and consequences of sexual and physical violence in the Mozambican context. Hospital records from 2019 at the pediatric emergency and forensic medicine units of Maputo Central Hospital were scrutinized using a standardized form. Of the 321 cases identified, 60% resulted from sexual violence. Girls represented 86.4% of the victims of sexual violence and boys, 66.1% of those from physical violence. Being injured in a familiar environment and by a parent, a relative, or someone known was strikingly common. The injury pattern varied by form of violence and sex of the child. About half of the injuries sustained by physical violence were minor/superficial. Severe injuries requiring hospitalization (33% in total) and some specialized care (27% in total) were mainly sustained by girl victims of sexual violence. While circumstances and consequences of violence-related injuries have several similarities, being severely injured is more typical of girl victims of sexual violence. Besides medical care, hospital services in Mozambique must be prepared to offer pediatric victims of violence the necessary social care.

Excess Mortality During the COVID-19 Pandemic in Guatemala

Objectives. To describe excess mortality during the COVID-19 pandemic in Guatemala during 2020 by week, age, sex, and place of death. Methods. We used mortality data from 2015 to 2020, gathered through the vital registration system of Guatemala. We calculated weekly mortality rates, overall and stratified by age, sex, and place of death. We fitted a generalized additive model to calculate excess deaths, adjusting for seasonality and secular trends and compared excess deaths to the official COVID-19 mortality count. Results. We found an initial decline of 26% in mortality rates during the first weeks of the pandemic in 2020, compared with 2015 to 2019. These declines were sustained through October 2020 for the population younger than 20 years and for deaths in public spaces and returned to normal from July onward in the population aged 20 to 39 years. We found a peak of 73% excess mortality in mid-July, especially in the population aged 40 years or older. We estimated a total of 8036 excess deaths (95% confidence interval = 7935, 8137) in 2020, 46% higher than the official COVID-19 mortality count. Conclusions. The extent of this health crisis is underestimated when COVID-19 confirmed death counts are used. (Am J Public Health. 2021;111(10): 1839-1846. https://doi.org/10.2105/AJPH.2021.306452).

Design and implementation of a multifaceted injury prevention intervention in Bedouin children in southern Israel

BACKGROUND

Child injury is prevalent in the Bedouin community of southern Israel, with higher injury rates compared with the general population. Bedouin children aged 0-4 were twice as likely as children from other population groups to suffer any injury, and for example, incidence of burns in Bedouin children was 0.91/1000 children, compared with 0.46/1000 in Jewish children.

METHODS

A multifaceted injury prevention intervention was developed based on best practice methods, culturally adapted and implemented in nine Bedouin towns in collaboration with local authorities. Intervention elements included a youth leadership scheme, workshops for mothers in maternal child health centres, home safety visits, a preschool intervention and a media campaign. Outcome assessment of change following home visits was conducted. Process evaluation included a survey of mothers and focus groups with youth participants.

RESULTS

High participation was demonstrated indicating acceptability of the programme. Assessment of home visits showed an improvement in the level of household safety between first and second visits, as measured by a checklist. Youth participants expressed satisfaction in the programme, which gave them confidence and practical tools.

CONCLUSION

A multifaceted intervention programme was conducted in the Bedouin community in southern Israel and found to be acceptable, with high participation levels. Collaboration between national and local authorities improved implementation, and multiple programmes in different settings enabled broad exposure to the programme.

Changes in the behaviour of monocyte subsets in acute post-traumatic sepsis patients

Trauma remains a major public health problem worldwide, marked as the fourth leading cause of death among all diseases. Trauma patients who survived at initial stages in the Emergency Department (ED), have significantly higher chances of mortality due to sepsis associated complications in the ICU at the later stage. There is paucity of literature regarding the role of circulating monocytes subsets and development of sepsis complications following trauma haemorrhagic shock (THS). The study was conducted to investigate the circulating level of monocyte subsets (Classical, Inflammatory, and Patrolling) and its functions in patients with acute post-traumatic sepsis. A total 72, THS patients and 30 age matched healthy controls were recruited. Blood samples were collected at different time points on days 1, 7, and 14 to measure the serum levels of cytokines by Cytometric bead assay (CBA), for the immunophenotyping of monocytes subsets, and also for the cell sorting of monocytes subsets for the functional studies. The circulating levels of monocytes subsets were found to be significantly differs among THS patients, who developed sepsis when compared with others who did not. The levels of patrolling monocytes were elevated in THS patients who developed sepsis and showed negative correlation with Sequential organ failure assessment (SOFA) score on days 7 and 14. Classical monocytes responded strongly to bacterial TLR-agonist (LPS) and produced anti-inflammatory cytokines, whereas patrolling monocytes responded with viral TLR agonist TLR-7/8 (R848) and produced inflammatory cytokines in post-traumatic sepsis patients. In conclusion, this study shows disparity in the behaviour of monocytes subsets in patients with acute post-traumatic sepsis.

Pattern and risk factors for childhood injuries in Dar es Salaam, Tanzania

Background

Injuries contribute to morbidity and mortality in children. This study was carried out to describe the pattern of childhood injuries and associated risk factors in Dar es Salaam, Tanzania.

Methods

This case control study was conducted in six selected health facilities in Dar es Salaam, Tanzania. Data were collected using a structured questionnaire. Cases and controls were children below 18 years who had suffered injuries and those without injury associated condition respectively.

Results

A total of 492 cases and 492 controls were included in the study, falls (32%), burns (26%), Road Traffic Injuries (14%) and cuts (10%) were the major types of injuries identified. Younger parents/guardians {Adjusted odds ratio (AOR)= 1.4; 95% CI: 1.4 -3.6}, more than six people in the same house (AOR= 1.8; 95% CI: 1.3–2.6), more than three children in the house {AOR= 1.4; 95% CI (1.0–2.0)}, absence of parent/guardian at time of injury occurrence (AOR= 1.6; 95% CI: 1.1–2.3), middle socio-economic (AOR=1.6; 95%CI: 1.1–2.4) and low socio-economic status (AOR= 1.5; 95% CI: 1.0–2.1) were independent risk factors for childhood injury.

Conclusion

Falls, burns and road traffic injuries were the main injury types in this study. Inadequate supervision, overcrowding, lower socio-economic status and low maternal age were significant risk factors for childhood injuries.

Evaluation of the effectiveness, implementation and cost-effectiveness of the Stay One Step Ahead home safety promotion intervention for pre-school children: a study protocol

BACKGROUND

Unintentional injuries in children under the age of 5 years commonly occur in the home and disproportionately affect those living in disadvantaged circumstances. Targeted home safety promotion should be offered to families most at risk but there is a paucity of standardised evidence-based resources available for use across family-support practitioners.

OBJECTIVE

To assess the effectiveness, implementation and cost-effectiveness of a 2-year home safety programme (Stay One Step Ahead) developed by parents, practitioners and researchers, and delivered by a range of family support providers in inner-city localities, compared with usual care in matched control localities.

METHODS

Parents of children aged 0 to 7 months will be recruited to a controlled before and after observational study. The primary outcome is home safety assessed by the proportion of families with a fitted and working smoke alarm, safety gate on stairs (where applicable) and poisons stored out of reach, assessed using parent-administered questionnaires at baseline, 12 and 24 months.Secondary outcomes include: the impact on other parent-reported safety behaviours, medically-attended injuries, self-efficacy for home safety and knowledge of child development and injury risk using questionnaires and emergency department attendance data; implementation (reach, acceptability, barriers, facilitators) of home safety promotion assessed through interviews and observations; and cost-effectiveness using medically-attended injury costs ascertained from healthcare records.

CONCLUSION

If shown to be effective and cost-effective this study will provide a practical resource to underpin national guidance. The study could inform public health prevention strategies to reduce home injury in children most at risk, while delivering cost savings to health and care services.

Overloaded and Unrestrained: A Qualitative Study with Local Experts Exploring Factors Affecting Child Car Restraint Use in Cape Town, South Africa

(1) Background: Children in South Africa experience significant impacts from road injury due to the high frequency of road crashes and the low uptake of road safety measures (including the use of appropriate child restraints). The current study aimed to assess the feasibility of a child restraint program and to describe factors influencing child restraint use from the perspectives of clinicians, representatives of non-government agencies, and academics in Cape Town, South Africa. (2) Methods: Qualitative interviews were conducted with 13 experts from government, academic and clinical backgrounds. Findings were analyzed using the COM-B component of the Behaviour Change Wheel and were grouped by the layers of the social-ecological model (individual, relational, community and societal). (COM-B is a framework to explain behaviour change which has three key components; capability, opportunity and motivation), (3) Results: Experts believed that there was a need for a child restraint program that should be staged and multifactorial. Participants described knowledge gaps, perceptions of risk, mixed motivations and limited enforcement of child restraint legislation as key influences of restraint use. (4) Conclusions: The results demonstrate potential areas on which to focus interventions to increase child restraint use in Cape Town, South Africa. However, this will require a coordinated and consistent response across stakeholder groups.
