Structural adverse childhood experiences associated with suicidal ideation, suicide attempts, and repetitive nonsuicidal self-injury among racially and ethnically minoritized youth.

INTRODUCTION: High rates of suicidal ideation (SI), suicide attempts (SA), and repetitive nonsuicidal self-injury (NSSI) among some ethnoracially minoritized United States youth populations may be related to adverse childhood experiences (ACEs) with structural roots. METHODS: Using the 2013-2019 Minnesota Student Surveys, we assessed associations of student-reported structural ACEs (parental incarceration, housing instability, food insecurity, and foster care involvement) with SI, SA, and repetitive NSSI within the past 12 months using multilevel logistic regression stratified by ethnoracial group (American Indian/Alaskan Native [AIAN], Hmong, other Asian, Black Latino, other Latino, Somali, other Black/African American [AA], Native Hawaiian/Pacific Islander [NHPI], and multiracial), and adjusted for sex, grade, ACEs experienced within one's household, mental health treatment, and perceived safety. RESULTS: Structural ACEs were strongly associated with increasing SI, SA, and NSSI. At ≥2 structural ACEs, repetitive NSSI rates ranged from 7% to 29% (female), 8% to 20% (male); SA rates ranged from 13% to 35% (female), 10% to 22% (male); and SI rates ranged from 31% to 50% (female), 20% to 32% (male). Black Latino, NHPI, AIAN, and Black/AA students most often reported structural ACE exposures. CONCLUSION: Reducing structural ACEs may reduce SI, SA, and repetitive NSSI among ethnoracially minoritized youth populations. Disaggregating diverse youth groups revealed variations in these outcomes that remain hidden when subpopulations are aggregated.

Racial Arrest Disparities in the USA by Rural-Urban Location and Region.

BACKGROUND: Urban racial arrest disparities are well known. Emerging evidence suggests that rural policing shares similar patterns as urban policing in the USA, but without receiving the same public scrutiny, raising the risk of biased rural policing going unnoticed. METHODS: We estimated adult and adolescent arrest rates and rate ratios (RR) by race, rural-urban status, and US region based on 2016 Uniform Crime Reporting Program arrest and US Census population counts using general estimating equation Poisson regression models with a 4-way interaction between race, region, age group, and urbanicity. RESULTS: With few exceptions, arrest rates were highest in small towns and rural areas, especially among Black and American Indian populations. Arrest rates differed between US regions with highest rates and racial disparities in the Midwest. For example, arrest rates among Black adults in the rural Midwest were 148.6 arrests [per 1000 population], 95% CI 131.4-168.0, versus 94.4 arrests, 95% CI 77.2-115.4 in the urban Midwest; and versus corresponding rural Midwest arrests among white adults, 32.7 arrests, 95% CI 30.8-34.8, Black versus white rural RR 4.54, 95% CI 4.09-5.04. Racial arrest disparities in the South were lower but still high, e.g., rural South, Black versus White adults, RR 1.86, 95% CI 1.71-2.03. CONCLUSIONS: Rural areas and small towns are potential hotspots of racial arrest disparities across the USA, especially in the Midwest. Approaches to overcoming structural racism in policing must include strategies targeted at rural/small town communities. Our findings underscore the importance of dismantling racist policing in all US communities.

Efficacy of Health Promotion Interventions Aimed to Improve Health Gains in Middle-Aged Adults-A Systematic Review.

Population aging will be one of the major social transformations in the coming decades, with a very significant impact in all countries. The consequences of this will cause an overload of social and health services. It will be necessary to prepare for an aging population. The promotion of healthy lifestyles is necessary to increase quality of life and well-being as people age. The aim of this study was to identify and synthesize interventions in middle-aged adults that promote healthy lifestyles and translate this knowledge into health gains. We performed a systematic review of the literature with research on the EBSCO Host-Research Databases platform. The methodology followed the PRISMA guidelines, and the protocol was registered with PROSPERO. A total of 10 articles out of 44 retrieved were included in this review, which identified interventions to promote healthy lifestyles with an impact on well-being, quality of life, and adherence to healthy behaviors. The synthesized evidence supports the efficacy of interventions that contributed to positive changes at the biopsychosocial level. Health promotion interventions were educational or motivational and related to physical exercise, healthy eating, and changes in habits and lifestyles related to harmful behaviors (tobacco use, excess carbohydrates in the diet, physical inactivity, and stress). The health gains found were increased mental health knowledge (self-actualization), adherence to physical exercise, improvement in physical condition, adherence to the consumption of fruits and vegetables, increased quality of life, and well-being. Health promotion interventions in middle-aged adults can significantly improve healthy lifestyles, protecting them from the negative effect of aging. For aging to be a successful experience, continuity of healthy lifestyles practiced in middle age is necessary.

Effectiveness of a Mobile App to Increase Risk Perception of Tobacco, Alcohol, and Marijuana Use in Mexican High School Students: Quantitative Study.

BACKGROUND: Young people have the highest rate of drug use worldwide. Recent data from Mexico in this population show that the prevalence of illicit drug use doubled between 2011 and 2016 (2.9%-6.2%), with marijuana being the one with the highest increase (2.4%-5.3%), but also point out that alcohol and tobacco use have remained steady or decreased. Mexican adolescents are at high risk for drug use owing to a low perception of risk and the availability of drugs. Adolescence is an ideal period to reduce or prevent risky behaviors using evidence-based strategies. OBJECTIVE: In this study, we aimed to test the short-term effectiveness of a mobile intervention app ("What Happens if you Go Too Far?" ["¿Qué pasa si te pasas?"]) that seeks to increase risk perception of tobacco, alcohol, and marijuana use in a sample of Mexican high school students. METHODS: A nonexperimental evaluation based on pretest-posttest design was used to measure the effectiveness of a preventive intervention using a mobile app, "What Happens If You Go Too Far?" The dimensions analyzed were knowledge of drugs and their effects, life skills, self-esteem, and risk perception. The intervention was conducted on a high school campus with 356 first-year students. RESULTS: The sample included 359 first-year high school students (mean 15, SD 0.588 years; women: 224/359, 62.4% men: 135/359, 37.6%). The intervention increased the overall risk perception of tobacco (χ24=21.6; P<.001) and alcohol use (χ24=15.3; P<.001). There was no significant difference in the perception that it is dangerous to smoke 5 cigarettes, and there was a marginal difference in the perception that it is very dangerous to smoke 1 cigarette or to use alcohol or marijuana. We used a generalized estimating equation method to determine the impact of the variables on risk perception. The results showed that knowledge about smoking increased the risk perception of smoking 1 cigarette (odds ratio [OR] 1.1065, 95% CI 1.013-1.120; P=.01), and that knowledge about marijuana use (OR 1.109, 95% CI 1.138-1.185; P=.002) and self-esteem (OR 1.102, 95% CI 1.007-1.206; P=.04) produced significant increases in the risk perception of consuming 5 cigarettes. Resistance to peer pressure and assertiveness also increased the perceived risk of using tobacco and alcohol. CONCLUSIONS: The intervention has the potential to increase the perception of risk toward drug use in high school students by providing knowledge about the effects and psychosocial risks of drug use and by strengthening life skills that are associated with increased risk perception. The use of mobile technologies in intervention processes may broaden the scope of preventive work for adolescents.

End-of-life perspectives according to family caregivers of older adults with dementia: A qualitative study.

BACKGROUND: Family caregivers are primarily responsible for the care of older adults with dementia, and the demands of this care increase as the end of life approaches. Experiencing the end of a family member's life can be stressful, and caregivers consider important to know how to identify when their loved one is approaching the end of life in order to prepare for this moment. Thus, as the family is primarily responsible for the older adult with dementia, it is essential to know the meanings of the end of life attributed by family caregivers. OBJECTIVE: To analyze the perceptions of family caregivers of older adults with dementia about the end of life. METHODS: This is a qualitative, descriptive and exploratory study. The convenience sample consisted of family caregivers of older adults with dementia. The inclusion criteria were being a family member directly involved in the care of the older adult with dementia and being 18 years of age or older. Data were collected from individual semi-structured interviews. The number of participants was defined during the interviews using the saturation criterion. Data were analyzed using the thematic analysis technique. RESULTS: A total of 63 family caregivers participated, 74.6% of whom were women, predominantly wives and daughters. Two themes resulted from the data analysis: (i) Different perspectives on the end of life: from death itself to a sad, painful and long grief process; and (ii) End of life in the perspective of transcendence. The meaning of the end of life was perceived in different ways by family caregivers. Understanding how they perceive and experience the end-of-life process of the older adult with dementia helps to clarify the best ways for the health professionals to approach and intervene with these families.

Transitions of Care in Cystic Fibrosis.

The development of formal transition models emerged to reduce variability in care, including cystic fibrosis (CF) responsibility, independence, self-care, and education (RISE), which provides a standardized transition program, including knowledge assessments, self-management checklists, and milestones for people with CF. Despite these interventions, the current landscape of health care transition (HCT) remains suboptimal, and additional focused attention on HCT is necessary. Standardization of assessment tools to gauge the efficacy of transfer from pediatric to adult care is a high priority. Such tools should incorporate both clinical and patient-centered outcomes to provide a comprehensive picture of progress and deficiencies of the HCT process.

Harnessing the Electronic Medical Record to Improve the Utilization of Ultrasound Screening for Abdominal Aortic Aneurysms.

PURPOSE: The US Preventive Services Task Force recommends one-time ultrasound screening to detect abdominal aortic aneurysms (AAAs) in male smokers. Despite this recommendation, AAA screening is still underutilized. The aim of this study was to determine the effectiveness of an electronic medical record (EMR) automated ordering program in increasing AAA screening at an integrated health care system. METHODS: This study was a retrospective chart review of patients who underwent ultrasound screening for AAA from January 1, 2016, to December 31, 2021, at a geographically isolated integrated health care system. An automated ordering system was implemented in a stepwise fashion within our EMR beginning in March 2019. The number of ultrasound studies and the incidence of AAA were compared between manual referral and EMR automated ordering periods. RESULTS: A total of 4,176 patients met the inclusion criteria for this study, among whom 148 aneurysms were identified. There was an increase in the average number of monthly screening ultrasound studies performed during the automated ordering period compared with the manual referral period (105 vs 16.3 studies, P < .001). The incidence of AAA was lower in the automated ordering period compared with the manual referral period (3.2% vs 5.3%, P = .013). CONCLUSIONS: An EMR automated ordering program can increase the number of screening ultrasound studies performed for AAA, which may help clinicians identify more high-risk aneurysms requiring urgent repair.

US Mass public shootings since Columbine: victims per incident by race and ethnicity of the perpetrator.

White individuals in the United States (US) have historically had disproportionate access to firearms. The real-life availability of firearms, including those most lethal, may still be greater among White populations, manifesting in the number of victims in shootings. We compared the severity of US mass public shootings since Columbine by race and/or ethnicity of the perpetrator using The Violence Project Database of Mass Shooters, assessing fatalities (minimum four), total victims, type, and legal status of guns used. We used data visualization and Quasi-Poisson regression of victims minus four - accounting for truncation at 4 fatalities - to assess fatality and total victim rates comparing Non-Hispanic (NH) White with NH Black shooters, using winsorization to account for outlier bias from the 2017 Las Vegas shooting. In 104 total mass public shootings until summer 2021, NH White shooters had higher median fatalities (6 [IQR 5-9] versus 5 [IQR 4-6]) and total victims (9 [IQR 6-19] versus 7 [IQR 5-12]) per incident. Confidence intervals of NH Black versus NH White fatalities rate ratios (RR) ranged from 0.17-1.15, and of total victim RRs from 0.15-1.04. White shooters were overrepresented in mass public shootings with the most victims, typically involving legally owned assault rifles. To better understand the consequences when firearms are readily available, including assault rifles, we need a database of all US gun violence. Our assessment of total victims beyond fatalities emphasizes the large number of US gun violence survivors and the need to understand their experiences to capture the full impact of gun violence.

The recovery position for maintenance of adequate ventilation and the prevention of cardiac arrest: A systematic review.

Aim: To conduct a systematic review of the use of the recovery position in adults and children with non-traumatic decreased levels of responsiveness changes outcomes in comparison with other positioning strategies. Methods: We searched Medline (Ovid), Embase, Cochrane Library, CINAHL, medRxiv and Google Scholar from inception to 15 March 2021 for studies involving adults and children in an out-of-hospital, first aid setting who had reduced levels of responsiveness of non-traumatic aetiology but did not require resuscitative interventions. We used the ROBINS-I tool to assess risk of bias and GRADE methodology to determine the certainty of evidence. Results: Of 17,947 citations retrieved, three prospective observational studies and four case series were included. The prone and semi-recumbent positions were associated with a decreased rate of suspected aspiration pneumonia in acute poisoning. Use of the recovery position in paediatric patients with decreased levels of responsiveness was associated with a deceased admission rate and the prone position was the position most commonly associated with sudden unexpected death in epilepsy. High risk of bias, imprecision and indirectness of evidence limited our ability to perform pooled analyses. Conclusion: We identified a limited number of observational studies and case series comparing outcomes following use of the recovery position with outcomes when other patient positions were used. There was limited evidence to support or revise existing first aid guidance; however, greater emphasis on the initial assessment of responsiveness and need for CPR, as well as the detection and management of patient deterioration of a person identified with decreased responsiveness, is recommended.

Detection of Antimicrobial Resistance, Pathogenicity, and Virulence Potentials of Non-Typhoidal Salmonella Isolates at the Yaounde Abattoir Using Whole-Genome Sequencing Technique.

One of the crucial public health problems today is the emerging and re-emerging of multidrug-resistant (MDR) bacteria coupled with a decline in the development of new antimicrobials. Non-typhoidal Salmonella (NTS) is classified among the MDR pathogens of international concern. To predict their MDR potentials, 23 assembled genomes of NTS from live cattle (n = 1), beef carcass (n = 19), butchers' hands (n = 1) and beef processing environments (n = 2) isolated from 830 wet swabs at the Yaounde abattoir between December 2014 and November 2015 were explored using whole-genome sequencing. Phenotypically, while 22% (n = 5) of Salmonella isolates were streptomycin-resistant, 13% (n = 3) were MDR. Genotypically, all the Salmonella isolates possessed high MDR potentials against several classes of antibiotics including critically important drugs (carbapenems, third-generation cephalosporin and fluoroquinolone). Moreover, >31% of NTS exhibited resistance potentials to polymyxin, considered as the last resort drug. Additionally, ≤80% of isolates harbored "silent resistant genes" as a potential reservoir of drug resistance. Our isolates showed a high degree of pathogenicity and possessed key virulence factors to establish infection even in humans. Whole-genome sequencing unveiled both broader antimicrobial resistance (AMR) profiles and inference of pathogen characteristics. This study calls for the prudent use of antibiotics and constant monitoring of AMR of NTS.

Duration of cooling with water for thermal burns as a first aid intervention: A systematic review.

BACKGROUND: Cooling thermal burns with running water is a recommended first aid intervention. However, guidance on the ideal duration of cooling remains controversial and inconsistent across organisations. AIM: To perform a systematic review of the evidence for the question; Among adults and children with thermal burn, does active cooling using running water as an immediate first aid intervention for 20 min or more, compared with active cooling using running water for any other duration, change the outcomes of burn size, burn depth, pain, adverse outcome (hypothermia) or complications? METHOD: We searched Medline, Embase, Cochrane Database of Systematic Reviews and used ROBINS-I to assess for risk of bias. We used Grading of Recommendations, Assessment, Development and Evaluation methodology for determining the certainty of evidence. We included all studies that compared the selected outcomes of the duration of cooling of thermal burns with water in all patient ages. (PROSPERO registration number: CRD42021180665). From 560 screened references, we included four observational studies. In these studies, 48% of burns were cooled for 20 min or more. We found no benefit for a duration of 20 min or more of cooling when compared with less than 20 min of cooling for the outcomes of size and depth of burn, re-epithelialization, or skin grafting. The evidence is of very low certainty owing to limitations in study design, risk of bias and indirectness. CONCLUSION: The optimal duration of cooling for thermal burns remains unknown and future prospective research is indicated to better define this treatment recommendation.

Phylogenetic Distribution of Ralstonia solanacearum Species Complex Populations in Potato in Kenya.

Ralstonia solanacearum is a pathogen causing bacterial wilt disease of potato, resulting in 70% potato production losses in Kenya. A study was conducted to determine the diversity of R. solanacearum species complex strains within the main potato-growing regions of Kenya. Potato tubers were collected in different potato-growing regions of Kenya from visibly wilted potato plants as well as samples of tomato, irrigation water, and cultures for pathogen isolation. Genomic DNA was isolated from 135 purified cultures of RSSC isolates and PCR-amplified using multiplex and sequevar primers targeting the endoglucanase (egl) partial gene sequences. Pathogenicity tests using R. solanacearum strain (phylotype II sequevar I) were done on the cultivars Kenya Karibu, Shangi, Chulu, Wanjiku, and MoneyMaker. Phylogenetic analysis of the partial egl gene identified two genospecies, R. pseudosolanacearum sp. nov. (1.5%) and R. solanacearum (98.5%). All R. solanacearum strains clustered in sequevar I and were distributed in all the potato-growing regions surveyed. The cultivars were grown in a greenhouse for two cycles in a randomized complete block design and inoculated with R. solanacearum strain. The severity scores were assessed and the area under the disease progress curve (AUDPC) was determined. All the cultivars tested for pathogenicity exhibited wilting symptoms at varying intervals after infection, with none showing complete resistance to R. solanacearum. Cultivar Shangi exhibited minimum disease severity and progression of 41.14% and AUDPC of 1041.7, respectively, while 'Kenya Karibu' was the most susceptible with a high progression rate of 68.24% and AUDPC of 1897.5, respectively. 'MoneyMaker', 'Chulu', and 'Wanjiku' showed no significant difference in disease severity, depicting a simultaneous rate of infection among them. These findings provide valuable information to better understand the pathogen genetic diversity in Kenya and how it spreads.

African Swine Fever Virus (ASFV): Biology, Genomics and Genotypes Circulating in Sub-Saharan Africa.

African swine fever (ASF) is a highly infectious and fatal haemorrhagic disease of pigs that is caused by a complex DNA virus of the genus Asfivirus and Asfarviridae African suids family. The disease is among the most devastating pig diseases worldwide including Africa. Although the disease was first reported in the 19th century, it has continued to spread in Africa and other parts of the world. Globally, the rising demand for pork and concomitant increase in transboundary movements of pigs and pork products is likely to increase the risk of transmission and spread of ASF and pose a major challenge to the pig industry. Different genotypes of the ASF virus (ASFV) with varying virulence have been associated with different outbreaks in several countries in sub-Saharan Africa (SSA) and worldwide, and understanding genotype circulation will be important for ASF prevention and control strategies. ASFV genotypes unique to Africa have also been reported in SSA. This review briefly recounts the biology, genomics and genotyping of ASFV and provides an account of the different genotypes circulating in SSA. The review also highlights prevention, control and progress on vaccine development and identifies gaps in knowledge of ASFV genotype circulation in SSA that need to be addressed.

The Etiology of Childhood Pneumonia in The Gambia: Findings From the Pneumonia Etiology Research for Child Health (PERCH) Study.

BACKGROUND: Pneumonia remains the leading cause of death in young children globally. The changing epidemiology of pneumonia requires up-to-date data to guide both case management and prevention programs. The Gambia study site contributed a high child mortality, high pneumonia incidence, low HIV prevalence, Haemophilus influenzae type b and pneumococcal conjugate vaccines-vaccinated rural West African setting to the Pneumonia Etiology Research for Child Health (PERCH) Study. METHODS: The PERCH study was a 7-country case-control study of the etiology of hospitalized severe pneumonia in children 1-59 months of age in low and middle-income countries. Culture and nucleic acid detection methods were used to test nasopharyngeal/oropharyngeal swabs, blood, induced sputum and, in selected cases, lung or pleural fluid aspirates. Etiology was determined by integrating case and control data from multiple specimens using the PERCH integrated analysis based on Bayesian probabilistic methods. RESULTS: At The Gambia study site, 638 cases of World Health Organization-defined severe and very severe pneumonia (286 of which were chest radiograph [CXR]-positive and HIV-negative) and 654 age-frequency matched controls were enrolled. Viral causes predominated overall (viral 58% vs. bacterial 28%), and of CXR-positive cases respiratory syncytial virus (RSV) accounted for 37%, Streptococcus pneumoniae 13% and parainfluenza was responsible for 9%. Nevertheless, among very severe cases bacterial causes dominated (77% bacterial vs. 11% viral), led by S. pneumoniae (41%); Mycobacterium tuberculosis, not included in "bacterial", accounted for 9%. 93% and 80% of controls ≥1 year of age were, respectively, fully vaccinated for age against Haemophilus influenzae and S. pneumoniae. CONCLUSIONS: Viral causes, notably RSV, predominated in The Gambia overall, but bacterial causes dominated the severest cases. Efforts must continue to prevent disease by optimizing access to existing vaccines, and to develop new vaccines, notably against RSV. A continued emphasis on appropriate case management of severe pneumonia remains important.

The first genotype II African swine fever virus isolated in Africa provides insight into the current Eurasian pandemic.

African swine fever (ASF) caused by the African swine fever virus (ASFV) is ranked by OIE as the most important source of mortality in domestic pigs globally and is indigenous to African wild suids and soft ticks. Despite two ASFV genotypes causing economically devastating epidemics outside the continent since 1961, there have been no genome-level analyses of virus evolution in Africa. The virus was recently transported from south-eastern Africa to Georgia in 2007 and has subsequently spread to Russia, eastern Europe, China, and south-east Asia with devastating socioeconomic consequences. To date, two of the 24 currently described ASFV genotypes defined by sequencing of the p72 gene, namely genotype I and II, have been reported outside Africa, with genotype II being responsible for the ongoing pig pandemic. Multiple complete genotype II genome sequences have been reported from European, Russian and Chinese virus isolates but no complete genome sequences have yet been reported from Africa. We report herein the complete genome of a Tanzanian genotype II isolate, Tanzania/Rukwa/2017/1, collected in 2017 and determined using an Illumina short read strategy. The Tanzania/Rukwa/2017/1 sequence is 183,186 bp in length (in a single contig) and contains 188 open reading frames. Considering only un-gapped sites in the pairwise alignments, the new sequence has 99.961% identity with the updated Georgia 2007/1 reference isolate (FR682468.2), 99.960% identity with Polish isolate Pol16_29413_o23 (MG939586) and 99.957% identity with Chinese isolate ASFV-wbBS01 (MK645909.1). This represents 73 single nucleotide polymorphisms (SNPs) relative to the Polish isolate and 78 SNPs with the Chinese genome. Phylogenetic analysis indicated that Tanzania/Rukwa/2017/1 clusters most closely with Georgia 2007/1. The majority of the differences between Tanzania/Rukwa/2017/1 and Georgia 2007/1 genotype II genomes are insertions/deletions (indels) as is typical for ASFV. The indels included differences in the length and copy number of the terminal multicopy gene families, MGF 360 and 110. The Rukwa2017/1 sequence is the first complete genotype II genome from a precisely mapped locality in Africa, since the exact origin of Georgia2007/1 is unknown. It therefore provides baseline information for future analyses of the diversity and phylogeography of this globally important genetic sub-group of ASF viruses.
