ABSTRACT

AIM: Schizophrenia is a leading cause of disability worldwide; early detection and intervention are critical. Early in their illness, individuals at clinical high-risk (CHR) for psychosis have subthreshold psychotic symptoms that are often derogatory and self-directed. We hypothesized that CHR participants with negative self-reference (NSR) as a component of subthreshold psychosis would also have higher levels of social anxiety and depression, lower self-esteem and lower social/role/global functioning as compared with CHR participants without NSR. METHODS: One hundred and sixty-eight participants from the National Institute of Mental Health (NIMH) funded Regroup Cognitive Behavioural Social Skills Training (CBSST) study were included. Clinical vignettes that included the Scale of Psychosis-Risk Symptoms were coded categorically to indicate whether NSR was present. t-tests were used to determine the association between NSR, symptom, and functional measures. RESULTS: Participants with NSR demonstrated significantly more social interaction anxiety (p < .001), negative beliefs about the self (p ≤ .001), defeatist beliefs (p < .05), depressive symptoms (p < .05) and positive symptoms (p < .005). There were no significant differences in social self-efficacy, positive or negative beliefs about others, positive beliefs about the self or psychosocial functioning between the two groups. CONCLUSIONS: Clinically significant differences were found between CHR participants with and without NSR, suggesting that this may be a useful factor to identify and address. Follow-up studies are needed to determine whether NSR responds to CBSST and whether or not its resolution would be associated with improvement in other symptom domains.

ABSTRACT

The SARS-CoV-2 Delta variant, first identified in October 2020, quickly became the dominant variant worldwide. We used publicly available data to explore the relationship between illness and death (peak case rates, death rates, case-fatality rates) and selected predictors (percentage vaccinated, percentage of the population >65 years, population density, testing volume, index of mitigation policies) in 45 high-income countries during the Delta wave using rank-order correlation and ordinal regression. During the Delta-dominant period, most countries reported higher peak case rates (57%) and lower peak case-fatality rates (98%). Higher vaccination coverage was protective against peak case rates (odds ratio 0.95, 95% CI 0.91-0.99) and against peak death rates (odds ratio 0.96, 95% CI 0.91-0.99). Vaccination coverage was vital to preventing infection and death from COVID-19 during the Delta wave. As new variants emerge, public health authorities should encourage the uptake of COVID-19 vaccination and boosters.

ABSTRACT

Viral genomic surveillance has been a critical source of information during the COVID-19 pandemic, but publicly available data can be sparse, concentrated in wealthy countries, and often made public weeks or months after collection. We used publicly available viral genomic surveillance data submitted to GISAID and GenBank to examine sequencing coverage and lag time to submission during 2020-2021. We compared publicly submitted sequences by country with reported infection rates and population and also examined data based on country-level World Bank income status and World Health Organization region. We found that as global capacity for viral genomic surveillance increased, international disparities in sequencing capacity and timeliness persisted along economic lines. Our analysis suggests that increasing viral genomic surveillance coverage worldwide and decreasing turnaround times could improve timely availability of sequencing data to inform public health action.

ABSTRACT

The COVID-19 pandemic challenged countries to protect their populations from this emerging disease. One aspect of that challenge was to rapidly modify national surveillance systems or create new systems that would effectively detect new cases of COVID-19. Fifty-five countries leveraged past investments in District Health Information Software version 2 (DHIS2) to quickly adapt their national public health surveillance systems for COVID-19 case reporting and response activities. We provide background on DHIS2 and describe case studies from Sierra Leone, Sri Lanka, and Uganda to illustrate how the DHIS2 platform, its community of practice, long-term capacity building, and local autonomy enabled countries to establish an effective COVID-19 response. With these case studies, we provide valuable insights and recommendations for strategies that can be used for national electronic disease surveillance platforms to detect new and emerging pathogens and respond to public health emergencies.

ABSTRACT

Global health security depends on effective surveillance systems to prevent, detect, and respond to disease threats. Real-time surveillance initiatives aim to develop electronic systems to improve reporting and analysis of disease data. Sierra Leone, with the support of Global Health Security Agenda partners, developed an electronic Integrated Disease Surveillance and Response (eIDSR) system capable of mobile reporting from health facilities. We estimated the economic costs associated with rollout of health facility eIDSR in the Western Area Rural district in Sierra Leone and projected annual direct operational costs. Cost scenarios with increased transport costs, decreased use of partner personnel, and altered cellular data costs were modeled. Cost data associated with activities were retrospectively collected and were assessed across rollout phases. Costs were organized into cost categories: personnel, office operating, transport, and capital. We estimated costs by category and phase and calculated per health facility and per capita costs. The total economic cost to roll out eIDSR to the Western Area Rural district over the 14-week period was US$64,342, a per health facility cost of $1,021. Equipment for eIDSR was the primary cost driver (45.5%), followed by personnel (35.2%). Direct rollout costs were $38,059, or 59.2% of total economic costs. The projected annual direct operational costs were $14,091, or $224 per health facility. Although eIDSR equipment costs are a large portion of total costs, annual direct operational costs are projected to be minimal once the system is implemented. Our findings can be used to make decisions about establishing and maintaining electronic, real-time surveillance in Sierra Leone and other low-resource settings.

ABSTRACT

The Global Health Security Agenda aims to improve countries' ability to prevent, detect, and respond to infectious disease threats by building or strengthening core capacities required by the International Health Regulations (2005). One of those capacities is the development of surveillance systems to rapidly detect and respond to occurrences of diseases with epidemic potential. Since 2015, the US Centers for Disease Control and Prevention (CDC) has worked with partners in Sierra Leone to assist the Ministry of Health and Sanitation in developing an Integrated Disease Surveillance and Response (IDSR) system. Beginning in 2016, CDC, in collaboration with the World Health Organization and eHealth Africa, has supported the ministry in the development of Android device mobile data entry at the health facility for electronic IDSR (eIDSR), also known as health facility-based eIDSR. Health facility-based eIDSR was introduced via a pilot program in 1 district, and national rollout began in 2018. With more than 1,100 health facilities now reporting, the Sierra Leone eIDSR system is substantially larger than most mobile-device health (mHealth) projects found in the literature. Several technical innovations contributed to the success of health facility-based eIDSR in Sierra Leone. Among them were data compression and dual-mode (internet and text) message transmission to mitigate connectivity issues, user interface design tailored to local needs, and a continuous-feedback process to iteratively detect user or system issues and remediate challenges identified. The resultant system achieved high user acceptance and demonstrated the feasibility of an mHealth-based surveillance system implemented on a national scale.

ABSTRACT

Nearly 40 million persons in the United States have a disability, as defined by responses to six questions recommended by the U.S. Department of Health and Human Services as the national standard for identifying disabilities in population-based health surveys (1). Although these questions have been used to estimate prevalence of functional disabilities overall, as well as types of functional disabilities (disability type), no study has yet investigated the characteristics of U.S. adults by number of disability types. Knowing the characteristics of persons living with multiple disability types is important for understanding the overall functional status of these persons. CDC analyzed data from the family component of the National Health Interview Survey (NHIS) for the years 2011-2014 to estimate the percentage of adults aged 18-64 years with one, two, three, or four or more disability types, by selected demographic and socioeconomic characteristics. Overall, 22.6 million (11.9%) working-age adults were found to have any disability, and in this population, most (12.8 million) persons had only one disability type. A generally consistent pattern between increasing indicators of low socioeconomic status and the number of disability types was observed. Understanding the demographic and socioeconomic characteristics of working-age adults with disabilities, including those with multiple disability types, might help to further the inclusion of persons with disabilities in public health programs and policies.

ABSTRACT

On January 14, 2016, the Sierra Leone Ministry of Health and Sanitation was notified that a buccal swab collected on January 12 from a deceased female aged 22 years (patient A) in Tonkolili District had tested positive for Ebola virus by reverse transcription-polymerase chain reaction (RT-PCR). The most recent case of Ebola virus disease (Ebola) in Sierra Leone had been reported 4 months earlier on September 13, 2015 (1), and the World Health Organization had declared the end of Ebola virus transmission in Sierra Leone on November 7, 2015 (2). The Government of Sierra Leone launched a response to prevent further transmission of Ebola virus by identifying contacts of the decedent and monitoring them for Ebola signs and symptoms, ensuring timely treatment for anyone with Ebola, and conducting an epidemiologic investigation to identify the source of infection.

ABSTRACT

Efforts to improve clinical preventive services (CPS) receipt among women with disabilities are poorly understood and not widely disseminated. The reported results represent a 2-year, Centers for Disease Control and Prevention and Association of Maternal and Child Health Programs partnership to develop a central resource for existing tools that are of potential use to maternal and child health practitioners who work with women with disabilities. Steps included contacting experts in the fields of disability and women's health, searching the Internet to locate examples of existing tools that may facilitate CPS receipt, convening key stakeholders from state and community-based programs to determine their potential use of the tools, and developing an online Toolbox. Nine examples of existing tools were located. The tools focused on facilitating use of the CPS guidelines, monitoring CPS receipt among women with disabilities, improving the accessibility of communities and local transportation, and training clinicians and women with disabilities. Stakeholders affirmed the relevance of these tools to their work and encouraged developing a Toolbox. The Toolbox, launched in May 2013, provides information and links to existing tools and accepts feedback and proposals for additional tools. This Toolbox offers central access to existing tools. Maternal and child health stakeholders and other service providers can better locate, adopt and implement existing tools to facilitate CPS receipt among adolescent girls with disabilities who are transitioning into adult care as well as women with disabilities of childbearing ages and beyond.

ABSTRACT

BACKGROUND: Adults with disabilities are less active and have higher rates of chronic disease than the general population. Given the health benefits of physical activity, understanding physical activity, its relationship with chronic disease, and health professional recommendations for physical activity among young to middle-age adults with disabilities could help increase the effectiveness of health promotion efforts. METHODS: Data from the 2009-2012 National Health Interview Survey (NHIS) were used to estimate the prevalence of, and association between, aerobic physical activity (inactive, insufficiently active, or active) and chronic diseases (heart disease, stroke, diabetes, and cancer) among adults aged 18-64 years by disability status and type (hearing, vision, cognitive, and mobility). The prevalence of, and association between, receiving a health professional recommendation for physical activity and level of aerobic physical activity was assessed using 2010 data. RESULTS: Overall, 11.6% of U.S. adults aged 18-64 years reported a disability, with estimates for disability type ranging from 1.7% (vision) to 5.8% (mobility). Compared with adults without disabilities, inactivity was more prevalent among adults with any disability (47.1% versus 26.1%) and for adults with each type of disability. Inactive adults with disabilities were 50% more likely to report one or more chronic diseases than those who were physically active. Approximately 44% of adults with disabilities received a recommendation from a health professional for physical activity in the past 12 months. CONCLUSIONS: Almost half of adults with disabilities are physically inactive and are more likely to have a chronic disease. Among adults with disabilities who visited a health professional in the past 12 months, the majority (56%) did not receive a recommendation for physical activity. IMPLICATIONS FOR PUBLIC HEALTH: These data highlight the need for increased physical activity among persons with disabilities, which might require support across societal sectors, including government and health care.

ABSTRACT

BACKGROUND: One way to prevent frequent hospitalizations and promote positive health outcomes among patients with heart failure (HF) is to ensure that the amount and quality of self-care used is appropriate to the patient's situation. OBJECTIVES: The following are the purposes of this study: (a) examine the frequency of performance of self-care behaviors, (b) describe personal and environmental factors (basic conditioning factors [BCFs]) that affect self-care behaviors, and (c) describe the relationship between the level of knowledge patients have to empower their performance of self-care and the actual performance of self-care behaviors. METHODS: This descriptive correlational study was guided by Orem's theory of self-care. One hundred ten participants, predominantly African Americans, who were outpatients or inpatients ready for hospital discharge, 18 years or older, and diagnosed with HF that was confirmed by an ejection fraction of 40% or less were conveniently selected from 1 of 2 sites. Data were collected with 2 investigator-developed instruments: the Revised Heart Failure Self-Care Behavior Scale and the Heart Failure Knowledge Test. Descriptive statistics, correlational analyses, and t tests for independent samples were used to analyze the data. RESULTS: Three of the top 5 most frequently performed self-care behaviors were related to taking prescribed medications, and the 5 least frequently performed self-care behaviors were concerned with symptom monitoring or management. There were no significant relationships between the total self-care behavior score and any of the BCFs; however, a number of significant relationships between BCFs and individual self-care behaviors were observed. There was a significant relationship between the mean total knowledge score and the total mean self-care score (r = 0.21, P =.026). CONCLUSION: Detailed information about the influence of BCFs on the performance of specific HF self-care behaviors can help nurses tailor interventions to the patient's situation.
