ABSTRACT

Recently, discussion of the potential of health literacy (HL) for health promotion has increased; however, clear evidence illuminating the relationship between adolescents’ HL and their physical activity (PA) remains scarce. This study aimed to assess the association between adolescents’ HL and leisure time PA. A representative cross-sectional study was conducted with 2,369 Lithuanian adolescents aged 13-16 years. A self-reported questionnaire gathered information regarding HL, leisure time PA, and other confounders (gender, age, family affluence and parents’ exercise). Descriptive statistics and the probabilities of being physically active were estimated using logistic regression. The results revealed that almost 60% of the participants were not sufficiently physically active. Having moderate or high levels of HL was positively associated with leisure time PA. Additionally, being male, belonging to a more affluent family, and having a father who exercise were significant predictors of adolescents’ leisure time PA. This study revealed that moderate and high HL positively related to leisure time PA among Lithuanian adolescents. The study results highlighted the importance of encouraging schoolchildren’s PA and including HL promotion in a school curriculum.

ABSTRACT

This study aims at investigating whether the livestock, lactation stage, or geographical origin of specialty milk in China could be classified by the elemental contents. Samples of goat, buffalo, and yak milk were collected from main production provinces in China and the contents of nine elements in milk from different livestock, regions, and lactation stages were determined. Statistical analysis indicated that the contents of Mn, Cu, As, Se, Cs, and Mo in mature milk were significantly different between the three livestock (p < 0.05). The trends of Mn and Cs contents of the goat milk and buffalo milk increased first and then decreased gradually during lactation. The contents of Se, Cs, Ba, and Mo in mature milk of three livestock were significantly different between the three regions (p < 0.05). The result of linear discriminant analysis (LDA) and partial least squares discrimination analysis (PLS-DA) showed that the total correct classification rates in different livestock for mature milk reached 86.7 and 90%. For goat milk, the total correct classification rates of different lactations and regions reached 88.9 and 77.8% for LDA (100 and 87.5% for PLS-DA), and followed by yak milk of different regions which achieved 88.9% for LDA (88.9% for PLS-DA). In summary, the microelements in milk showed a significant correlation with livestock, region, and lactation of goat, buffalo, and yak milk. The elemental fingerprints combined with the LDA could be potential for classifying the livestock, lactation stage, and geographical origin of milk. PRACTICAL APPLICATION: According to study the contents of miroelements in milk from different livestock, regions, and lactation stages, provide evidence and support for classifying the livestock, lactation stage, and geographical origin of milk.

ABSTRACT

AIMS AND OBJECTIVES: This study aimed to determine the relationship between nurses’ exposure to violence and their professional commitment during the COVID-19 pandemic.

BACKGROUND: Violence against nurses is a common problem that persists worldwide.

DESIGN: This was a descriptive cross-sectional study.

METHODS: An online questionnaire form and the Nursing Professional Commitment Scale were used to collect the data. The study was carried out online during the COVID-19 pandemic between October-December 2020. A total of 263 nurses agreed to participate in the study. The STROBE checklist was followed for observational studies.

RESULTS: During the COVID-19 pandemic, 8.4% of the nurses stated that they were exposed to physical violence, 57.8% to verbal violence, 0.8% to sexual violence and 61.6% to mobbing. 52.1% of the nurses stated that they thought of quitting the profession during the COVID-19 pandemic. The mean total Nursing Professional Commitment Scale score was 71.33 ± 15.05.

CONCLUSIONS: This study revealed that nurses’ exposure to physical, verbal and sexual violence during the COVID-19 pandemic decreased compared to before the pandemic. Nurses’ exposure to mobbing during the pandemic was found to increase. A statistically significant difference was found between the status of the nurses’ exposure to physical violence, verbal violence, and mobbing, working hours, number of patients given care, and their thoughts of quitting the profession. It was found that the status of exposure to physical violence, thinking of quitting the profession and working hours decreased professional commitment.

RELEVANCE TO CLINICAL PRACTICE: In the light of these results, it is recommended that measures to prevent violence should be addressed in a multifaceted way. In managing the pandemic process, the decisions and practices should not be left to the managers’ initiative to prevent mobbing. Initiatives that will increase nurses’ professional commitment during the pandemic process should be planned and implemented.

ABSTRACT

BACKGROUND: Visualization of aortic valve dynamics is important in diagnosing valvular diseases but is challenging to perform with magnetic resonance imaging (MRI) due to the limited temporal resolution.

PURPOSE: To develop an MRI technique with sub-millisecond temporal resolution and demonstrate its application in visualizing rapid aortic valve opening and closing in human subjects in comparison with echocardiography and conventional MRI techniques.

STUDY TYPE: Prospective.

POPULATION: Twelve healthy subjects.

FILED STRENGTH/SEQUENCE: 3 T; gradient-echo-train-based sub-millisecond periodic event encoded imaging (get-SPEEDI) and balanced steady-state free precession (bSSFP).

ASSESSMENT: Images were acquired using get-SPEEDI with a temporal resolution of 0.6 msec. get-SPEEDI was triggered by an electrocardiogram so that each echo in the gradient echo train corresponded to an image at a specific time point, providing a time-resolved characterization of aortic valve dynamics. For comparison, bSSFP was also employed with 12 msec and 24 msec temporal resolutions, respectively. The durations of the aortic valve rapid opening (T_ro ), rapid closing (T_rc ), and the maximal aortic valve area (AVA) normalized to height were measured with all three temporal resolutions. M-mode echocardiograms with a temporal resolution of 0.8 msec were obtained for further comparison.

STATISTICAL TEST: Parameters were compared between the three sequences, together with the echocardiography results, with a Mann-Whitney U test.

RESULTS: Significantly shorter T_ro (mean ± SD: 27.5 ± 6.7 msec) and T_rc (43.8 ± 11.6 msec) and larger maximal AVA/height (2.01 ± 0.29 cm² /m) were measured with get-SPEEDI compared to either bSSFP sequence (T_ro of 56.3 ± 18.8 and 63.8 ± 20.2 msec; T_rc of 68.2 ± 16.6 and 72.8 ± 18.2 msec; maximal AVA/height of 1.63 ± 0.28 and 1.65 ± 0.32 cm² /m for 12 msec and 24 msec temporal resolutions, respectively, P < 0.05). In addition, the get-SPEEDI results were more consistent with those measured using echocardiography, especially for T_ro (29.0 ± 4.1 msec, P = 0.79) and T_rc (41.6 ± 4.3 msec, P = 0.16). DATA CONCLUSION: get-SPEEDI allows for visualization of human aortic valve dynamics and provided values closer to those measured using echocardiography than the bSSFP sequences.

ABSTRACT

INTRODUCTION: The objective of this report was to evaluate perceptions of psoriatic arthritis (PsA) treatment and satisfaction with healthcare professional (HCP) communication among patients with PsA in Australia, compared with overall global perceptions.

METHODS: Data were collected via a global and country-specific survey (The Harris Poll; November 2, 2017-March 12, 2018). Eligible patients were ≥ 18 years old, had been diagnosed with PsA > 1 year prior, had seen a rheumatologist or dermatologist within the past 12 months, and had previously received ≥ 1 conventional synthetic or biologic disease-modifying antirheumatic drug. Data reported by patients included baseline demographics, overall health, time since PsA diagnosis, PsA severity, satisfaction with current PsA medication and management, and experiences regarding communication with their HCP. Descriptive statistics were obtained.

RESULTS: Most patients in Australia were very or somewhat satisfied with their PsA medication, and reported always or often taking their medication exactly as directed by their HCP. However, the majority still experienced symptoms, reported their overall health as poor or fair, and would change something about their PsA medication. While the majority of patients in Australia were satisfied with the communication with their HCP, most would prefer increased communication but some felt that asking too many questions would affect the quality of their care. Perceptions in Australia were similar to global perceptions.

CONCLUSIONS: Although most patients with PsA in Australia were satisfied with their disease management and communication with their HCP, many still experienced symptoms, would change something about their PsA medication, and would prefer increased communication with their HCP.

ABSTRACT

Apurinic/apyrimidinic endonuclease 1/redox-factor 1 (APE1/Ref-1) gene encodes a multifunctional protein involved in the DNA base excision repair (BER) pathway, which initiates repair of apurinic/apyrimidinic (AP) sites in DNA by catalyzing hydrolytic incision of the phosphodiester backbone. APE1/Ref-1 polymorphisms are related to the occurrence of neural tube defects (NTDs), but the association between APE1/Ref-1 polymorphisms and NTDs is not reported in Chinese Han population. The aim of the present study was to evaluate the association of APE1/Ref-1 polymorphism and the risk of NTD occurrence for Han population in a high-risk area of China. APE1/Ref-1 genotypes were determined by iPLEX Gold SNP genotyping. AP sites and folate level of brain tissues were measured. The results showed that three polymorphisms (rs3136817, rs77794916, and rs1760944) of APE1/Ref-1 were statistically associated with NTD subtypes. Allele C of rs3136817, allele T of rs77794916, and allele G of rs1760944 were associated with an increased risk for encephalocele (OR = 2.52, 95% CI [1.25-5.07], P < 0.01; OR = 1.80, 95% CI [1.04-3.12], P = 0.04; and OR = 1.96, 95% CI [1.12-3.45], P = 0.02), compared with those harboring the alleles T, C, and T, respectively. The folate level in NTDs was lower than that in controls. DNA AP sites in the encephalocele were significantly higher than the control (P < 0.01). The three polymorphisms of APE1/Ref-1 were significantly related to NTD occurrence, which indicated that APE1/Ref-1 might be a potential genetic risk factor for encephalocele in a high-risk area of NTDs in China.

ABSTRACT

When a visual search target frequently appears in one target-rich region of space, participants learn to search there first, resulting in faster reaction time when the target appears there than when it appears elsewhere. Most research on this location probability learning (LPL) effect uses 2-dimensional (2D) search environments that are distinct from real-world search contexts, and the few studies on LPL in 3-dimensional (3D) contexts include complex visual cues or foraging tasks and therefore may not tap into the same habit-like learning mechanism as 2D LPL. The present study aimed to establish a baseline evaluation of LPL in controlled 3D search environments using virtual reality. The use of a virtual 3D search environment allowed us to compare LPL for information within a participant’s initial field of view to LPL for information behind participants, outside of the initial field of view. Participants searched for a letter T on the ground among letter Ls in a large virtual space that was devoid of complex visual cues or landmarks. The T appeared in one target-rich quadrant of the floor space on half of the trials during the training phase. The target-rich quadrant appeared in front of half of the participants and behind the other half. LPL was considerably greater in the former condition than in the latter. This reveals an important constraint on LPL in real-world environments and indicates that consistent search patterns and consistent egocentric spatial coding are essential for this form of visual statistical learning in 3D environments.

ABSTRACT

SETTING: The Canadian Community Health Survey (CCHS) is one of the world’s largest ongoing cross-sectional population health surveys, with over 130,000 respondents every two years or over 1.1 million respondents since its inception in 2001. While the survey remains relatively consistent over the years, there are differences between cycles that pose a challenge to analyze the survey over time.

INTERVENTION: A program package called cchsflow was developed to transform and harmonize CCHS variables to consistent formats across multiple survey cycles. An open science approach was used to maintain transparency, reproducibility and collaboration.

OUTCOMES: The cchsflow R package uses CCHS survey data between 2001 and 2014. Worksheets were created that identify variables, their names in previous cycles, their category structure, and their final variable names. These worksheets were then used to recode variables in each CCHS cycle into consistently named and labelled variables. Following, survey cycles can be combined. The package was then added as a GitHub repository to encourage collaboration with other researchers.

IMPLICATION: The cchsflow package has been added to the Comprehensive R Archive Network (CRAN) and contains support for over 160 CCHS variables, generating a combined data set of over 1 million respondents. By implementing open science practices, cchsflow aims to minimize the amount of time needed to clean and prepare data for the many CCHS users across Canada.

ABSTRACT

In a 2018 report titled, Quantifying the Epidemic of Prescription Opioid Overdose Deaths, four senior analysts of the Centers for Disease Control and Prevention (CDC), including the head of the Epidemiology and Surveillance Branch, acknowledged for the first time that the number of prescription opioid overdose deaths reported by the CDC in 2016 was erroneous. The error, they said, was caused by miscoding deaths involving illicitly manufactured fentanyl (IMF) as deaths involving prescribed fentanyl. To understand what caused this error, the authors examined the CDC’s methodology for compiling drug-related mortality data, beginning with the source data obtained from approximately 2.8 million death certificates received each year from state vital statistics registrars. Systemic problems often begin outside the CDC, with a surprisingly high rate of errors and omissions in the source data. Using the CDC’s explanation for what caused the error, the authors show why an international program used by the CDC for reporting mortality is ill-suited for compiling and reporting drug overdose deaths. Except for heroin, methadone, and opium, each of which has an individual program code, all other opioids are separated in just two program codes according to whether they are synthetic or semisynthetic/opiates. Methadone-involved deaths pose a special problem for the CDC because methadone has dual indications for treating pain and for treating opioid use disorder (OUD). In 2019, more than seven times more methadone was administered or dispensed for OUD treatment than was prescribed for pain, yet all methadone-involved deaths are coded by the CDC as involving the prescribed form of the drug. The authors conclude that the CDC was at fault for failing to recognize and correct this problem before 2016. Public policy consequences of this failure are briefly mentioned.

ABSTRACT

BACKGROUND: Hemodialysis patients present a dramatic increase in cardiovascular morbidity/mortality. Circulating immune cells, activated by both uremic milieu and dialysis, play a key role in the pathogenesis of dialysis-related vascular disease. The aim of our study was to identify, through a high-throughput approach, differences in gene expression profiles in the peripheral blood mononuclear cells (PBMCs) of patients treated with on-line hemodiafiltration and bicarbonate hemodialysis.

METHODS: The transcriptomic profile was investigated in PBMCs isolated from eight patients on on-line hemodiafiltration and eight patients on bicarbonate hemodialysis by microarray analysis. The results were evaluated by statistical and functional pathway analysis and validated by real time PCR (qPCR) in an independent cohort of patients (on-line hemodiafiltration N = 20, bicarbonate hemodialysis n = 20).

RESULTS: Eight hundred and forty-seven genes were differentially expressed in patients treated with on-line hemodiafiltration and bicarbonate hemodialysis. Thirty-seven functional gene networks were identified and atherosclerosis signaling was the top canonical pathway regulated by on-line hemodiafiltration. Among the genes of this pathway, on-line hemodiafiltration was associated with a reduced expression of Platelet-derived growth factor A chain (PDGF A), Clusterin, Monoamine Oxidase A, Interleukin-6 (IL-6) and Vascular Endothelial Growth Factor C (VEGF-)C and with an increase of Apolipoprotein E. qPCR confirmed the microarray results. Platelet derived growth factor AA (PDGF-AA), IL-6 and VEGF-C serum levels were significantly lower in the on-line hemodiafiltration group. Finally, 10 patients previously on bicarbonate hemodialysis were switched to on-line hemodiafiltration and PBMCs were harvested after 6 months. The qPCR results from this perspective group confirmed the modulation of atherosclerotic genes observed in the cross-sectional analysis.

CONCLUSIONS: Our data suggest that type of dialysis (on-line hemodiafiltration versus bicarbonate hemodialysis) may modulate the expression of several genes involved in the pathogenesis of atherosclerotic disease.
