ABSTRACT

BACKGROUND AND HYPOTHESIS: Children exposed to socioenvironmental adversities (eg, urbanicity, pollution, neighborhood deprivation, crime, and family disadvantage) are more likely to subsequently develop subclinical psychotic experiences during adolescence (eg, hearing voices, paranoia). However, the pathways through which this occurs have not been previously investigated. We hypothesized that cognitive ability and inflammation would partly explain this association.

STUDY DESIGN: Data were utilized from the Environmental-Risk Longitudinal Twin Study, a cohort of 2232 children born in 1994-1995 in England and Wales and followed to age 18. Socioenvironmental adversities were measured from birth to age 10 and classified into physical risk (defined by high urbanicity and air pollution) and socioeconomic risk (defined by high neighborhood deprivation, neighborhood disorder, and family disadvantage). Cognitive abilities (overall, crystallized, fluid, and working memory) were assessed at age 12; and inflammatory markers (C-reactive protein, interleukin-6, soluble urokinase plasminogen activator receptor) were measured at age 18 from blood samples. Participants were interviewed at age 18 regarding psychotic experiences.

STUDY RESULTS: Higher physical risk and socioeconomic risk were associated with increased odds of psychotic experiences in adolescence. The largest mediation pathways were from socioeconomic risk via overall cognitive ability and crystallized ability, which accounted for ~11% and ~19% of the association with psychotic experiences, respectively. No statistically significant pathways were found via inflammatory markers in exploratory (partially cross-sectional) analyses.

CONCLUSIONS: Cognitive ability, especially crystallized ability, may partly explain the association between childhood socioenvironmental adversity and adolescent psychotic experiences. Interventions to support cognitive development among children living in disadvantaged settings could buffer them against developing subclinical psychotic phenomena.

ABSTRACT

Alzheimer’s disease (AD) is a debilitating neurodegenerative disorder, characterized by memory deficit and dementia. AD is considered a multifactorial disorder where multiple processes like amyloid-beta and tau accumulation, axonal degeneration, synaptic plasticity, and autophagic processes plays an important role. In this study, the spatial proteomic differences in the neonatal 5xFAD brain tissue were investigated using MALDI-MSI coupled to LC-MS/MS, and the statistically significantly altered proteins were associated with AD. Thirty-five differentially expressed proteins (DEPs) between the brain tissues of neonatal 5xFAD and their littermate mice were detected via MALDI-MSI technique. Among the 35 proteins identified, 26 of them were directly associated with AD. Our results indicated a remarkable resemblance in the protein expression profiles of neonatal 5xFAD brain when compared to AD patient specimens or AD mouse models. These findings showed that the molecular alterations in the AD brain existed even at birth and that some proteins are neurodegenerative presages in neonatal AD brain. HIGHLIGHTS: Spatial proteomic alterations in the 5xFAD mouse brain compared to the littermate. 26 out of 35 differentially expressed proteins associated with Alzheimer’s disease (AD). Molecular alterations and neurodegenerative presages in neonatal AD brain. Alterations in the synaptic function an early and common neurobiological thread.

ABSTRACT

OBJECTIVES: This study aimed to identify barriers to the proper use of antibiotics by healthcare professionals and to help the hospital Antimicrobial Stewardship develop suitable actions for the staff.

METHODS: In a Belgian teaching hospital, a survey was conducted among physicians, pharmacists, and nurses involved in antibiotherapy. Questions from the 2019 European Center for Disease Prevention and Control (ECDC) survey were analyzed based on components of the COM-B model (capabilities, opportunities, and motivations). First, collected data were reviewed with the Ethnos software to analyze the different COM-B model components. For statistical analyses, responses were grouped into three clear-cut answers in a Fisher’s exact test.

RESULTS: Overall, 400 staff members were included. We found that our professions, combined, have a good perception of antibiotic resistance (97.8%). For capabilities, however, only 77.2% state that they have sufficient knowledge, with 91.3%, 71.5%, and 63.0% for physicians, nurses, and pharmacists, respectively. For opportunities (access to resources, information, and training), it is observed that 72.2% report having easy access to the guidelines they need to manage infections. In comparison, for 64.2% of the respondents, this information changed their opinion on the useless or inappropriate prescription, administration, and delivery of antibiotics. For 55.0%, this information has enabled them to change their practices. Finally, for motivations, 92.8% of respondents state that they know about the link between their practices and the emergence and spread of antibiotic resistance. However, only 65.0% of participants say they have a role in managing antibiotic resistance. We found that 5 out of 8 questions are significantly dependent on the profession: 2 inquiries related to capability, 1 to opportunity, and 2 to motivation.

CONCLUSION: We found that responses to the ECDC questionnaire are related to the profession. While some topics are universal/cross-functional, others must be explicitly tailored to each professional category. Information is useless if not accessible. Communication and provision of documents are thus paramount.

ABSTRACT

BACKGROUND: Sentinel events (SEs) can result in severe and unwanted outcomes. To minimize the fear of sentinel events reporting and the occurrence of sentinel events, patient safety culture improvements within healthcare organizations is needed. To our knowledge, limited studies explored the relationships between patient safety culture and sentinel events on a local level and no research has been conducted at the national level in Saudi Arabia.

OBJECTIVES: This study aimed to explore the relationships between the patient safety culture and the reported-SEs on a national level during the year 2020 in Saudi hospitals.

METHODS: This was a descriptive study. We utilized two data sources (the reported-SEs and the patient safety culture survey) that were linked using hospitals information. To explore the relationships between patient safety culture and reported-SEs rates, we performed descriptive statistics, a test of independence, post-hoc analysis, correlation analysis, and multivariate regression and stepwise analyses.

RESULTS: The highest positive domain scores in patient safety culture domains in the Saudi hospitals (n = 366) were “Teamwork Within Units” (80.65%) and “Organizational learning-continuous improvement” (80.33%), and the lowest were “Staffing” (32.10%) and “Nonpunitive Response to Error” (26.19%). The highest numbers of reported-SEs in 103 hospitals were related to the contributory factors of “Communication and Information” (63.20%) and “Staff Competency and Performance” (61.04%). The correlation analysis performed on 89 Saudi hospitals showed that higher positive patient safety culture scores were significantly associated with lower rates of reported-SEs in 3 out of the 12 domains, which are “Teamwork Within Units”, “Communication Openness”, and “Handoffs and Transitions”. Multivariate analyses showed that “Handoffs and Transitions”, “Nonpunitive Response to Error”, and “Teamwork Within Units” domains were significant predictors of the number of SEs. The “Staff Competency and Performance” and “Environmental Factors” were the most contributory factors of SEs in the number of significant correlations with the patient safety culture domains.

CONCLUSION: This study identified patient safety culture areas of improvement where hospitals in Saudi Arabia need actions. Our study confirms that a more positive patient safety culture is associated with lower occurrence of sentinel events. To minimize the fear of sentinel events reporting and to improve overall patient safety a culture change is needed by promoting a blame-free culture and improving teamwork, handoffs, and communication openness.

ABSTRACT

BACKGROUND: Distal first metatarsal osteotomy is used to correct mild or moderate hallux valgus (HV). We designed a cadaveric study to compare the resistance to axial load between two percutaneous distal first metatarsal osteotomies: Bösch osteotomy and percutaneous chevron. The first aim of this study was to develop a systematic technique for measuring the sagittal displacement on lateral foot X-rays. Our second objective was to measure the resistance to axial load for both of these osteotomies.

METHODS: Ten pairs of freshly frozen cadaveric feet were randomly assigned to one of the two techniques investigated. Pre- and post-operative lateral X-rays were obtained. After surgery, the feet were placed under progressive axial loads up to 60 kg. Metaphyseo-diaphyseal angle (MDA) and the distance between bone fragments were measured, and the differences between the two techniques were statistically assessed.

RESULTS: The MDA decreased in both surgical techniques. The mean plantar tilt was -6.90 degrees (SD = 10.251) for chevron osteotomy and -5.34 degrees (SD = 16.621) for Bösch osteotomy. There was no significant difference between the techniques (p = 0.41). Regarding the distance between the bone fragments, the Bösch osteotomy produced more plantar displacement than the chevron osteotomy, which was statistically significant for the 10 and 20 kg loads (p = 0.031 and 0.04, respectively). At loads ≥ 30 kg, the bone fragment distance did not differ significantly between the techniques (p = 0.114).

CONCLUSIONS: Although the chevron technique confers higher stability regarding fragment displacement during axial loading, both techniques increase the plantar angulation of the metatarsal head.

LEVEL OF EVIDENCE: Cadaveric study.

ABSTRACT

BACKGROUND: Individuals experiencing multimorbidity have more complex healthcare needs, use more healthcare services, and access multiple service providers across the healthcare continuum. They also experience higher rates of functional decline. Rehabilitation therapists are well positioned to address these functional needs; however, little is known about the influence of rehabilitation therapy on patient outcomes, and subsequent unplanned healthcare utilization for people with multimorbidity. The aims of this study were to: 1) describe and compare the characteristics of people with multimorbidity receiving: home care rehabilitation therapy alone, other home care services without rehabilitation therapy, and the combination of home care rehabilitation therapy and other home care services, and 2) determine the association between home care rehabilitation therapy and subsequent healthcare utilization among those recently discharged from an acute care unit.

METHODS: This retrospective cohort study used linked health administrative data housed within ICES, Ontario, Canada. The cohort included long-stay home care clients experiencing multimorbidity who were discharged from acute care settings between 2007-2015 (N = 43,145). Descriptive statistics, ANOVA’s, t-tests, and chi-square analyses were used to describe and compare cohort characteristics. Multivariable logistic regression was used to understand the association between receipt of rehabilitation therapy and healthcare utilization.

RESULTS: Of those with multimorbidity receiving long-stay home care services, 45.5% had five or more chronic conditions and 46.3% required some assistance with ADLs. Compared to people receiving other home care services, those receiving home care rehabilitation therapy only were less likely to be readmitted to the hospital (OR = 0.78; 95% CI: 0.73-0.83) and use emergency department services (OR = 0.73; 95% CI: 0.69-0.78) within the first 3-months following hospital discharge.

CONCLUSIONS: Receipt of rehabilitation therapy was associated with less unplanned healthcare service use when transitioning from hospital to home among persons with multimorbidity. These findings suggest rehabilitation therapy may help to reduce the healthcare burden for individuals and health systems. Future research should evaluate the potential cost savings and health outcomes associated with providing rehabilitation therapy services for people with multimorbidity.

ABSTRACT

BACKGROUND: Acute pancreatitis in pregnancy (APIP) with a high risk of death is extremely harmful to mother and fetus. There are few models specifically designed to assess the severity of APIP. Our study aimed to establish a clinical model for early prediction of severity of APIP.

METHODS: A retrospective study in a total of 188 patients with APIP was enrolled. The hematological indicators, IAP (intra-abdominal pressure) and clinical data were obtained for statistical analysis and prediction model construction.

RESULTS: According to univariate and multivariate logistic regression analysis, we found that red cell distribution width (RDW), neutrophil-lymphocyte ratio (NLR) and Intra-abdominal pressure (IAP) are prediction indexes of the severity in APIP (p-value < 0.05). Our novel clinical prediction model was created by based on the above three risk factors and showed superior predictive power in primary cohort (AUC = 0.895) and validation cohort (AUC = 0.863). A nomogram for severe acute pancreatitis in pregnancy (SAPIP) was created based on the three indicators. The nomogram was well-calibrated.

CONCLUSION: RDW, NLR and IAP were the independent risk factors of APIP. Our clinical prediction model of severity in APIP based on RDW, NLR and IAP with predictive evaluation is accurate and effective.

ABSTRACT

BACKGROUND AND AIM: Lack of knowledge on COVID-19 among people and healthcare staff significantly impacts late management and its rapid transmission. Dental students must be aware of the exact preventive instructions due to their close contact with patients and clinical work in the dental setting during the pandemic. This interventional study aimed to investigate the effectiveness of designed educational content regarding COVID-19 on Iranian dental students’ knowledge, attitudes, and practices at Alborz University of medical sciences.

MATERIALS AND METHODS: A total of 88 dental students were investigated in this study. Educational content was designed based on the clinical guidelines regarding COVID-19 in dentistry. The content was presented to dental students as a three-hour webinar. In addition, the online, validated questionnaire was obtained from the students as pre, post, and follow-up surveys.

RESULTS: A statistically significant difference between students’ knowledge, attitudes, and practices were obtained before and after the intervention and the follow-up survey. 48.58% improvement in knowledge score, 6.37% in attitudes, and 17% in practice scores were observed.

CONCLUSION: Although this educational intervention significantly improved the knowledge, attitude, and practice of dental students, additional education and clinical training are mandatory for effective and safe dental practice management in future crises.

ABSTRACT

BACKGROUND: Frailty is associated with mortality among older adults. We aimed to determine the appropriate time and frailty index (FI) threshold for frailty intervention in Chinese community-dwelling older adults.

METHODS: In this prospective cohort study, we used data from the 2011 wave of the Chinese Longitudinal Healthy Longevity Study. Follow-up was performed for seven years from baseline. Using the FI to evaluate frailty and define frailty status, we explored the best time point and FI score for frailty intervention, by comparing the relationships of FI and frailty status with mortality.

RESULTS: From 2011 to 2018, 8642 participants were included and followed-up. A total of 4458 participants died during the study period. After adjusting for variables such as age, sex, marital status, education level, and living conditions, the hazard ratio (HR) of mortality risk based on the FI at baseline was 37.484 (95% confidence interval [CI]: 30.217-46.498; P < 0.001); female sex, living in the city, being married, and living with spouse were found to be protective factors, whereas ageing was a risk factor for frailty. The mortality risk was higher in pre-frail than in frail participants (HR: 3.588, 95% CI: 3.212-4.009, P < 0.001). Piecewise linear regression analysis revealed an FI score threshold of 0.5. When the FI score was > 0.5, the HR of mortality based on the FI was 15.758 (95% CI: 3.656-67.924; P < 0.001); when the FI score was ≤ 0.5, the HR of mortality based on the FI was 48.944 (95% CI: 36.162-66.244; P < 0.001).

CONCLUSION: Using FI as a continuous variable to predict death is more accurate than frailty status. The advancement of early interventions for mortality risk reduction is more beneficial in pre-frail than in frail patients, and an FI score of 0.5 was found to be the threshold for mortality prediction using the FI.

ABSTRACT

BACKGROUND: In Nepal and across the globe, the COVID-19 pandemic has primed an environment for increased rates of violence against women (VAW). This paper explores pandemic-driven economic insecurity and increased alcohol use as instigators of VAW and Intimate Partner Violence (IPV) within newly married households in the rural, Nawalparasi region of Nepal.

METHODS: This study is a secondary analysis of data obtained from the Sumadhur Intervention pilot study that has been previously described and demonstrates successful implementation of group-based, household-level intervention for women’s empowerment and sexual and reproductive health education (1). Our three sets of data were collected before and during the COVID-19 pandemic. The first set is from a Longitudinal Cohort of 200 newly married women who were surveyed twice a year from February 2017 through July 2020. The second data set is a subset cohort of newly married women, their husbands, and their mothers-in-law (31 women, 31 husbands and 31 mothers-in-law) who participated in Sumadhur in January 2021. The third data set was obtained through in-depth interviews in July 2021 from 15 households following Sumadhur. The interviews were thematically coded, and subthemes were identified. A t-test of the January 2021 survey data set was run to look at correlations between income loss, alcohol consumption and experience of IPV among newly married women. All other survey data was analyzed for change over time.

RESULTS: At three months after the onset of the pandemic (July 2020), the Longitudinal Cohort survey data from newly married women reported increased rates of husbands’ alcohol use as well as personal experiences of IPV as compared to pre-pandemic averages. There was a statistically significant difference (p < 0.001) in the effects of income loss on increased alcohol use and experience of IPV. Qualitative results iterated the common theme of alcohol use and economic insecurity as upstream instigators of VAW in the community.

CONCLUSIONS: In the Nawalparasi district of Nepal, the pandemic has led to unstable economic situations that have instigated alcohol use among men, and increased rates of IPV among young, newly married women, and reports of VAW in the community. We have demonstrated a need for urgent programmatic and policy responses aimed at reducing VAW and IPV and protecting women during times of uncertainty and crisis.
