ABSTRACT

OBJECTIVES: Coronavirus disease 2019 (COVID-19) has emerged as a pandemic, affecting nearly 180 million people worldwide as of June 22, 2021. Previous studies have examined the association between the mean vitamin D (Vit D) concentration of each country and COVID-19 infection and mortality rate in European countries. The aim of the present study was to critically evaluate the relationship between prevalence of mild and severe Vit D deficiency in each country and COVID-19 infection, recovery, and mortality using updated data and a different methodological approach.

METHODS: Information on Vit D concentration or deficiency for each country was retrieved through a literature search. COVID-19 infections and mortalities per million people and total recoveries, as of June 22, 2021, were obtained. The associations between Vit D deficiency and COVID-19 infection, recovery, and mortality were explored using correlation coefficients and scatterplots.

RESULTS: Non-significant correlations were observed between both number of COVID-19 infections (r = 0.363, P = 0.116) and number of recoveries (r = 0.388, P = 0.091) and the prevalence of mild Vit D deficiency (<50 nmol/L). Similarly, non-significant correlations were observed between both infections (r = 0.215, P = 0.392) and recoveries (r = 0.242, P = 0.332) and the prevalence of severe Vit D deficiency (<30 nmol/L). Significant correlations were found between COVID-19 mortality and prevalence of both mild Vit D deficiency (r = 0.634, P = 0.003) and severe Vit D deficiency (r = 0.538, P = 0.021).

CONCLUSIONS: The prevalence of neither mild nor severe Vit D deficiency was associated with the number of COVID-19 infections in European countries. Thus, it is an important parameter to consider when implementing preventive measures to face COVID-19.

ABSTRACT

The mutational status of the variable region of the immunoglobulin heavy chain (IGHV) genes remains the most significant prognostic factor in chronic lymphocytic leukemia (CLL) patients. However, the groups of mutated (M) and unmutated (UM) patients are also heterogeneous, and additional markers are used for a more accurate prognosis. The aim of our work was to determine the prognostic value of the signs of antigen selection determined by BASELINe statistics in M IGHV sequences of CLL patients. Clinical data, IGHV gene configuration, TP53, NOTCH1, SF3B1 mutations were analyzed in 127 CLL patients with M IGHV sequences. The median OS of patients with negative selection in the framework regions (FWRs) of IGHV genes was 120 months compared to 202 month in other CLL patients (P = 0.016). In multivariate Cox regression analysis Binet stage C vs A + B (P < 0.0001), SF3B1 mutations (P < 0.0001), negative selection in the FWRs (HR P = 0.007), and age ≥65 years (P = 0.034) were powerful adverse prognostic factors for OS in CLL patients with M IGHV genes. These preliminary data suggest that the signs of antigen-driven selection may be used as a prognostic factor in CLL patients with M IGHV genes in combination with other markers.

ABSTRACT

The utility of traditional eating disorder measures in the assessment of muscularity-oriented disordered eating has been questioned. To address this limitation, the Muscularity-Oriented Eating Test (MOET) was recently developed and validated in a sample of U.S. college men. We aimed to develop a multicultural Spanish-language version of the MOET for use in Latin American samples and validate its use in a sample of Argentinian college men. Combined translation procedures were used to develop a version suitable for different Spanish-speaking populations. A total of 235 students (M_age = 23.47, SD = 5.61) participated in this study by completing a survey including the MOET. A sub-sample (n = 121) completed the MOET again after 1 week. A confirmatory factor analysis of a re-specified model of the original single-factor MOET, allowing for residual correlation between items associated to dietary rules (items 4-12), resulted in an adequate fit (χ²/df = 2.10, CFI = 0.94, TLI = 0.93, RMSEA 0.05 [90% CI = 0.04, 0.06] SRMR = 0.08). Further, the multicultural Spanish-language version of the MOET yielded evidence of internal consistency (omega = 0.83, 95% CI [0.79, 0.88], Cronbach’s α = 0.83), a 1-week Intraclass Correlation Coefficient was considered for test-retest reliability (ICC = 0.82), item analysis, convergent validity with measures of eating disorder psychopathology, body dissatisfaction and weight-related behaviors, as well as for divergent validity with an unrelated construct. The availability of a multicultural Spanish-language version of the MOET may have utility in both clinical and research efforts related to muscularity-oriented disordered eating among Latino men.

ABSTRACT

BACKGROUND: Drug overdose deaths involving stimulants, including cocaine and psychostimulants with abuse potential (e.g., methamphetamine), have been increasing, partly because of co-involvement with opioids. Stimulant-involved overdose deaths have disproportionately increased among non-Hispanic Black (Black) and non-Hispanic American Indian/Alaskan Native (AI/AN) persons; however, the role of opioids in exacerbating disproportionate stimulant-involved death rates is unclear.

METHODS: Analysis of National Vital Statistics System multiple cause-of-death mortality files examined age-adjusted cocaine- and psychostimulant-involved death rates. Analyses of death rates stratified by racial and ethnic group and opioid co-involvement included: 1) Joinpoint regression of 2004-2019 trends, 2) changes in rates from 2018 to 2019, and 3) demographic and geographic characteristics of 2019 deaths.

RESULTS: From 2004 to 2019, cocaine and psychostimulant-involved death rates were higher for Black and AI/AN persons, respectively. Among all groups, increases in cocaine-involved overdose rates were largely driven by opioid co-involvement, particularly after 2013. From 2004 to 2019, rates for psychostimulant-involved deaths increased with and without opioid co-involvement. Rates for overdoses co-involving cocaine and synthetic opioids increased from 2018 to 2019 for Hispanic, non-Hispanic White (White), and Black persons. Psychostimulant-involved overdose rates with and without synthetic opioid co-involvement increased among Hispanic, White, and Black persons. In 2019, Black and AI/AN persons continued to experience higher cocaine- and psychostimulant-involved death rates, respectively.

CONCLUSIONS: Stimulant-involved deaths continue to increase, and the role of opioids in driving these deaths varies by race and ethnicity. Ensuring equitable access to proven prevention and treatment interventions and incorporating social determinants of health into future research around effective pharmacotherapies may help reduce stimulant-involved overdose deaths.

ABSTRACT

OBJECTIVE: This systematic review and meta-analysis aimed to evaluate debriefing methods’ effectiveness on learning outcomes for nursing students.

DESIGN: A systematic review and meta-analysis were applied according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement.

DATA SOURCES: Publications were searched in PubMed, EMBASE, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, and WANFANG (China) databases from inception to 2020.

REVIEW METHODS: Two researchers independently retrieved articles and evaluated their quality. Review Manager version 5.3 software was used to conduct the meta-analysis, following the PRISMA guidelines. Bias risk was assessed using the Joanna Briggs Institute manual. Heterogeneity was assessed by I² statistics. Standardized mean difference (SMD) and 95% confidence intervals (CIs) were used for effect size analysis based on learning outcomes.

RESULTS: Sixteen studies were selected in the systematic review and 13 studies with 1637 nursing students were included in the meta-analysis. Five debriefing methods were used in the intervention group. The analysis showed that Debriefing for Meaningful Learning was more effective on the debriefing quality (SMD = 0.52, 95%CI [0.32, 0.72]), and that video-assisted debriefing was more effective on nursing students’ experiences (SMD = 0.30, 95%CI [0.02, 0.58]) and critical thinking (SMD = 0.90, 95%CI [0.65, 1.15]) compared with the usual debriefing. However, written debriefing did not show better effects on students’ experiences (SMD = -0.22, 95%CI [-0.51, 0.07]), and peer-led debriefing did not show better effects on the debriefing quality compared with the usual debriefing (SMD = -0.15, 95%CI [-1.43, -0.67]).

CONCLUSIONS: The study indicated that Debriefing for Meaningful Learning and video-assisted debriefing showed a positive impact on nursing education. Future studies that have larger sample sizes, high-quality debriefing methods, robust study designs, and other learning outcomes are required.

ABSTRACT

PURPOSE: Many individuals who get cancer may be exposed to stigmatization from their close relatives and their entourage. This cross-sectional and correlational study was conducted in order to determine stigmatization, discrimination and perception of illness among oncology patients in Northern Turkey.

METHOD: The sample of the study consisted of 367 inpatients who were hospitalized in the oncology and hematology clinics of a University Hospital in northern Turkey between 31.01.2019 and 30.07.2019. Data were collected using the demographics form, Cataldo Lung Cancer Stigma Scale and Illness Perception Questionnaire.

RESULTS: The mean total score of the patients according to Cataldo Lung Cancer Stigma Scale is 30.4 ± 8.8. In this study, no statistically significant relationship was determined between Cataldo Lung Cancer Stigma Scale total score and Illness Perception Questionnaire sub-dimension scores (p > .05). It can be said that the oncology patients were exposed to stigmatization and discrimination, and that certain socio demographic and clinical characteristics such as sex, marital status, education level, employment status, diagnosis, and the clinical phase of the disease are significant predictors of Cataldo Lung Cancer Stigma Scale scores.

CONCLUSIONS: In order to help them express their feelings in oncology patients, reduce their anxiety, increase their adaptation to their illness and treatment, help them cope with the multi-faceted crisis caused by the disease and improve their quality of life, cancer stigmatization should be evaluated objectively.

ABSTRACT

PURPOSE: This study aimed to identify the fear of cancer recurrence (FCR) among Korean breast cancer survivors and further explore their experiences based on their level of FCR.

METHODS: A mixed-methods study was conducted with a quantitative approach (phase I) followed by a qualitative approach (phase II) between August 2019 and February 2020.70 participants who completed the FCR inventory questionnaire were categorized into either high or low groups based on their FCR level. In phase II, in-depth interviews with 14 participants from phase I were conducted to explore their specific experiences of FCR.

RESULTS: 38 participants (54.3%) experienced high levels of FCR, characterized by higher severity of FCR, more reaction to triggers, higher stress levels, more functional impairments, more insight, and frequent reassurance-seeking behaviors than those with low levels of FCR. Differences in FCR levels by age were statistically significant (F = 6.83, p = .002), and participants younger than 50 years had significantly higher FCR scores than those aged 60 years and older. Of similarities and differences found between the two groups, qualitative findings showed that the experience of the high FCR group was characterized by “living with cancer but keeping a certain distance from fear of recurrence” and that of the low FCR group was characterized by “living a healing life while controlling latent fears.”

CONCLUSIONS: It is necessary to help those survivors who experience high FCR reduce its negative impact on their health. These findings can serve as a basis to develop a personalized approach with better understanding of the FCR among Korean women.

ABSTRACT

BACKGROUND AND AIMS: Colchicine reduces the risk of cardiovascular events in patients with coronary disease. Colchicine has broad anti-inflammatory effects and part of the atheroprotective effects have been suggested to be the result of NLRP3 inflammasome inhibition. We studied the effect of colchicine on extracellular vesicle (EV) NLRP3 protein levels and inflammatory markers, high sensitivity-CRP (hs-CRP) and interleukin (IL)-6, in patients with chronic coronary disease.

METHODS: In vitro, the NLRP3 inflammasome was stimulated in PMA-differentiated- and undifferentiated THP-1 cells. In vivo, measurements were performed in serum obtained from 278 participants of the LoDoCo2 trial, one year after randomization to colchicine 0.5 mg once daily or placebo. EVs were isolated using precipitation. NLRP3 protein presence in EVs was confirmed using iodixanol density gradient centrifugation. Levels of NLRP3 protein, hs-CRP and IL-6 were measured using ELISA.

RESULTS: In vitro, NLRP3 inflammasome stimulation showed an increase of EV NLRP3 protein levels. EV NLRP3 protein levels were lower in patients treated with colchicine (median 1.38 ng/mL), compared to placebo (median 1.58 ng/mL) (p = 0.025). No difference was observed in serum NLRP3 protein levels. Serum hs-CRP levels were lower in patients treated with colchicine (median 0.80 mg/L) compared to placebo (median 1.34 mg/L) (p < 0.005). IL-6 levels were lower in patients treated with colchicine (median 2.07 ng/L) compared to placebo (median 2.59 ng/L), although this was not statistically significant (p = 0.076).

CONCLUSIONS: Colchicine leads to a reduction of EV NLRP3 protein levels. This indicates that inhibitory effects on the NLRP3 inflammasome might contribute to the atheroprotective effects of colchicine in coronary disease.

ABSTRACT

Planning for bone tumor resection surgery is a technically demanding and time-consuming task, reliant on manual positioning of cutting planes (CPs). This work describes an automated approach for generating bone tumor resection plans, where the volume of healthy bone collaterally resected with the tumor is minimized through optimized placement of CPs. Particle swarm optimization calculates the optimal position and orientation of the CPs by introducing a single new CP to an existing resection, then optimizing all CPs to find the global minima. The bone bounded by all CPs is collaterally resected with the tumor. The approach was compared to manual resection plans from an experienced surgeon for 20 tumor cases. It was found that a greater number of CPs reduce the collaterally resected healthy bone, with diminishing returns on this improvement after five CPs. The algorithm-generated resection plan with equivalent number of CPs resulted in a statistically significant improvement over manual plans (paired t-test, p < 0.001). The described approach has potential to improve patient outcomes by reducing loss of healthy bone in tumor surgery while offering a surgeon multiple resection plan options.

ABSTRACT

BACKGROUND: Stroke is the second leading cause of death worldwide with heterogeneous characteristics. The subtypes of stroke are due to different pathophysiological regulations and causes. This study aimed to investigate the correlation of serum levels of apolipoprotein B 48, interleukin-1β and Homocysteine with BMI in patients with ischemic stroke (IS).

METHODS: Over one hundred controls (120) and an equal number of IS patients, including 31 women and 89 men, were recruited to participate in the case-control study conducted at Imam Reza Hospital (Tabriz, Iran) from February 2019 to March 2020. We measured serum levels of apolipoprotein B 48, interleukin-1β, and Homocysteine. Receiver operating characteristic analysis (ROC) was performed to evaluate the diagnostic value of these indices in patients and control groups.

RESULTS: The mean serum levels of apolipoprotein B 48, interleukin-1β, and Homocysteine, were significantly increased in the experimental group compared to the control group with a p-value of 0.001. The ROC curve analysis showed that the area under the curve for apo B48, IL -1β, hs-CRP, and Homocysteine serum levels were 0.94, 0.98, 0.99, and 1, respectively.

CONCLUSIONS: The results of our current study show that the determination of serum levels of apolipoprotein B 48, interleukin-1β, and Homocysteine can potentially be used to monitor and diagnose IS patients. However, there was no statistically significant correlation between serum levels of apolipoprotein B 48, interleukin 1β and Homocysteine and BMI in the patient group. However, there was a statistically significant inverse correlation between serum levels of high-sensitivity C-reactive protein (hs-CRP) and BMI in the patient group.
