From the day they are born: a qualitative study exploring violence against children with disabilities in West Africa.

BACKGROUND: Despite the building evidence on violence against children globally, almost nothing is known about the violence children with disabilities in low and middle-income countries (LMICs) experience. The prevalence of violence against children with disabilities can be expected to be higher in LMICs where there are greater stigmas associated with having a child with a disability, less resources for families who have children with disabilities, and wider acceptance of the use of corporal punishment to discipline children. This study explores violence experienced by children with disabilities based on data collected from four countries in West Africa- Guinea, Niger, Sierra Leone, and Togo. METHODS: A qualitative study design guided data generation with a total of 419 children, community members, and disability stakeholders. Participants were selected using purposive sampling. Stakeholders shared their observations of or experiences of violence against children with disabilities in their community in interviews and focus groups. Thematic analysis guided data analysis and identified patterns of meaning among participants' experiences. RESULTS: Results illuminate that children with disabilities experience violence more than non-disabled children, episodes of violence start at birth, and that how children with disabilities participate in their communities contributes to their different experiences of violence. CONCLUSIONS: The study recommends policy-oriented actions and prevention programs that include children and their families in strategizing ways to address violence.

Erosions after laparoscopic adjustable gastric banding: diagnosis and management.

OBJECTIVE: To define the changing prevalence of erosion after Laparoscopic Adjustable Gastric Banding (LAGB), describing the range of clinical presentations, the approaches to treatment and the outcomes from these approaches over a 15-year study period. BACKGROUND: A recent systematic review of the literature of erosion after LAGB identified 25 relevant studies and reported a total of 231 erosions in 15,775 patients giving an overall incidence of 1.46%. The review highlighted a broad variation of incidence from 0.2% to 33%. The review was unable to identify either common presentations or an optimal pattern of management. METHODS: Patients who underwent a primary LAGB operation between September 1994 and January 2010 by 2 surgeons (P.O.B. and W.B.) were identified in a prospectively maintained database. Those patients who had an erosion of their LAGB were identified. Presentation, operative details, demographics, body mass index, weight history, and perioperative problems were analyzed. RESULTS: In total, 2986 patients were identified. All bands placed were Lap-Bands (Allergan, CA). Hundred erosions were experienced by 85 patients (2.85%) at a median time of 33 months from initial surgery to the erosion (range: 11-170 months). The rate of erosion was highest when the band was placed by the perigastric approach at 6.77%. Since the adoption of the pars flaccida approach, the rate of erosion has dropped to 1.07%. The majority of patients who had experienced an erosion (71 patients; 83.5%) experienced only 1 erosion, 13 patients (15.3%) had 2 erosions, and 1 patient had 3 erosions. The most common presentation was loss of satiety. The band has been successfully replaced in 56 patients. It has been explanted in 27 patients and 2 patients were converted to other bariatric procedures. The weight loss in patients who had a LAGB reinserted after erosion was not significantly different to the background cohort. CONCLUSIONS: Erosion of LAGB is uncommon and its clinical course is benign. It is best treated with a staged surgical approach; initially, with removal and repair followed later by replacement. With this approach, weight loss is maintained and reerosion is uncommon.

The Social, Demographic, and Clinical Predictors of COVID-19 Severity: a Model-based Analysis of United States Veterans.

PURPOSE: This study aims to identify the contributions of individual and community social determinants of health (SDOH), demographic, and clinical factors in COVID-19 disease severity through a model-based analysis. METHODS: This national cross-sectional study focused on hospitalization among those tested for COVID-19 and use of intensive care, analyzing data on 220,848 Veterans tested between February 20, 2020 and October 20, 2021. Multiple logistic regression models were constructed using backwards elimination. The predictive value of each model was assessed with a c-statistic. RESULTS: Those hospitalized were older, more likely to be male, of Black or Asian race, have an income less than $39,999, live in an urban residence, and have medical comorbidities. The strongest predictors for hospitalization included Gini inequality index, race, income, heart failure, chronic kidney disease (CKD), and chronic obstructive pulmonary disease (COPD). For intensive care, Asian race, rural residence, COPD, and CKD were the strongest predictors. C-statistics were c = 0.749 for hospitalization and c = 0.582 for ICU admission. CONCLUSIONS: A combination of clinical, demographic, individual and community SDOH factors predict COVID-19 hospitalization with good predictive ability and can inform risk stratification, discharge planning, and public health interventions. Racial disparities were not explained by social or clinical factors. Intensive care models had low discriminative power and may be better explained by other characteristics.

Space-time clustering of COVID-19 cases in the United States veteran population.

PURPOSE: To assess the distribution and clustering of coronavirus disease 2019 (COVID-19) testing and incidence over space and time, U.S. Department of Veteran's Affairs (VA) data were used to describe where and when veterans experienced highest proportions of test positivity. METHODS: Data for 6,342,455 veterans who utilized VA services between January 1, 2018, and September 30, 2021, were assessed for COVID-19 testing and test positivity. Testing and positivity proportions by county were mapped and focused-cluster tests identified significant clustering around VA facilities. Spatial cluster analysis also identified where and when veterans experienced highest proportions of test positivity. RESULTS: Within the veterans study population and our time window, 21.3% received at least one COVID-19 test, and 20.4% of those tested had at least one positive test. There was statistically significant clustering of testing around VA facilities, revealing regional variation in testing practices. Veterans experienced highest test positivity proportions between November 2020 and January 2021 in a cluster of states in the Midwest, compared to those who received testing outside of the identified cluster (RR: 3.45). CONCLUSIONS: Findings reflect broad regional trends in COVID-19 positivity which can inform VA policy and resource allocation. Additional analysis is needed to understand patterns during Delta and Omicron variant periods.

Aedes aegypti abundance in urban neighborhoods of Maricopa County, Arizona, is linked to increasing socioeconomic status and tree cover.

BACKGROUND: Understanding coupled human-environment factors which promote Aedes aegypti abundance is critical to preventing the spread of Zika, chikungunya, yellow fever and dengue viruses. High temperatures and aridity theoretically make arid lands inhospitable for Ae. aegypti mosquitoes, yet their populations are well established in many desert cities. METHODS: We investigated associations between socioeconomic and built environment factors and Ae. aegypti abundance in Maricopa County, Arizona, home to Phoenix metropolitan area. Maricopa County Environmental Services conducts weekly mosquito surveillance with CO2-baited Encephalitis Vector Survey or BG-Sentinel traps at > 850 locations throughout the county. Counts of adult female Ae. aegypti from 2014 to 2017 were joined with US Census data, precipitation and temperature data, and 2015 land cover from high-resolution (1 m) aerial images from the National Agricultural Imagery Program. RESULTS: From 139,729 trap-nights, 107,116 Ae. aegypti females were captured. Counts were significantly positively associated with higher socioeconomic status. This association was partially explained by higher densities of non-native landscaping in wealthier neighborhoods; a 1% increase in the density of tree cover around the trap was associated with a ~ 7% higher count of Ae. aegypti (95% CI: 6-9%). CONCLUSIONS: Many models predict that climate change will drive aridification in some heavily populated regions, including those where Ae. aegypti are widespread. City climate change adaptation plans often include green spaces and vegetation cover to increase resilience to extreme heat, but these may unintentionally create hospitable microclimates for Ae. aegypti. This possible outcome should be addressed to reduce the potential for outbreaks of Aedes-borne diseases in desert cities.

The Complex Epidemiological Relationship between Flooding Events and Human Outbreaks of Mosquito-Borne Diseases: A Scoping Review.

BACKGROUND: Climate change is expected to increase the frequency of flooding events. Although rainfall is highly correlated with mosquito-borne diseases (MBD) in humans, less research focuses on understanding the impact of flooding events on disease incidence. This lack of research presents a significant gap in climate change-driven disease forecasting. OBJECTIVES: We conducted a scoping review to assess the strength of evidence regarding the potential relationship between flooding and MBD and to determine knowledge gaps. METHODS: PubMed, Embase, and Web of Science were searched through 31 December 2020 and supplemented with review of citations in relevant publications. Studies on rainfall were included only if the operationalization allowed for distinction of unusually heavy rainfall events. Data were abstracted by disease (dengue, malaria, or other) and stratified by post-event timing of disease assessment. Studies that conducted statistical testing were summarized in detail. RESULTS: From 3,008 initial results, we included 131 relevant studies (dengue n=45, malaria n=61, other MBD n=49). Dengue studies indicated short-term (<1 month) decreases and subsequent (1-4 month) increases in incidence. Malaria studies indicated post-event incidence increases, but the results were mixed, and the temporal pattern was less clear. Statistical evidence was limited for other MBD, though findings suggest that human outbreaks of Murray Valley encephalitis, Ross River virus, Barmah Forest virus, Rift Valley fever, and Japanese encephalitis may follow flooding. DISCUSSION: Flooding is generally associated with increased incidence of MBD, potentially following a brief decrease in incidence for some diseases. Methodological inconsistencies significantly limit direct comparison and generalizability of study results. Regions with established MBD and weather surveillance should be leveraged to conduct multisite research to a) standardize the quantification of relevant flooding, b) study nonlinear relationships between rainfall and disease, c) report outcomes at multiple lag periods, and d) investigate interacting factors that modify the likelihood and severity of outbreaks across different settings. https://doi.org/10.1289/EHP8887.

[Spinal muscular atrophy. A 4-year prospective, multicenter, longitudinal study (168 cases)]. / Amyotrophie spinale infantile. Etude multicentrique prospective et longitudinale de 168 cas suivis 4 ans.

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder characterised by motoneuron degeneration in the anterior horn of the spinal cord and in the bulbar nuclei. The various types of SMA are linked to the 5q13 locus in 95 % of cases. In the absence of an effective specific treatment, orthopaedic and respiratory management can significantly improve the prognosis. To study the contemporary natural history of SMA and to identify clinical and non invasive prognostic criteria, 168 patients with SMA were recruited in 6 hospital units (Lille, Lyon, Marseille, Paris) during a 4-year prospective multicenter follow-up study (1998-2002). Follow-up has now lasted at least 4 years in 151 cases (90%), and 24 of these patients have died Disease outcome was appraised by using three criteria: muscle strength, the sum of the motor function and examination index (IFM), the respiratory muscle paralysis index (IMR), and the dorsal decubitus forced vital capacity/theoretical index (ICV/CT). Statistical analysis showed a significant worsening (about 20%) of the three criteria during follow-up. The motor function and examination index (IFM) is particularly interesting: the difference between initial and final status was significant in all age groups and in all three types of the disease. The IFM may thus be useful as the main outcome measure during therapeutic trials.
