ABSTRACT

Clinical impressions suggest that forensic patients in Belgium have more complex needs regarding care and risk in recent years than before. In this article, we analyzed psychometric data regarding patients’ symptoms, risk estimates, antisocial personality traits, and functional capabilities over a 10-year span in a medium-security unit for rehabilitation of forensic patients. Data from a total of 129 patients with a main diagnosis of psychosis were analyzed. Results confirmed that patients had higher risk assessment estimates, more psychopathic/antisocial personality traits, and lower cognitive and functional capabilities. The average psychotic symptom levels and protective factors did not statistically change over the ten-year period. The changes are thought to be due to a new forensic law and the creation of new high- and medium-risk beds.

ABSTRACT

The Trail Making Test (TMT) is a popular measure of cognitive functioning, especially processing speed and cognitive flexibility. This study aims to provide normative data for the Slovak adult population. The secondary aim is to test the convergent validity by examining relationships of direct and derived indices to other neuropsychological measures. A sample of 487 healthy adults undertook neuropsychological testing. The relationships of TMT scores to demographic variables and other neuropsychological measures were tested. Age was positively correlated with TMT-A (r = 0.444, p < .01), TMT-B (r = 0.426, p < .01), and the B-A index (r = 0.317, p < .01). Years of education were negatively correlated with TMT-B (r = -0.183, p < .01), B-A difference (r = -0.188, p < .01) and B/A ratio (r = -0.119, p < .01). There were no statistically significant differences in performance based on gender. The test scores were correlated with other measures of processing speed and executive functions. Presented normative data are stratified into 7 age categories. For more accurate interpretation, regression equations were calculated to take years of education into account. TMT-A and B performance, as well as B-A difference score, must be interpreted in relation to age, while education can provide additional information. The B/A ratio is independent from age but should be also corrected for educational level.

ABSTRACT

Background: There has been much debate as to the importance of mechanical bowel preparation (MBP) and oral antibiotic agents (OAB) prior to elective colorectal surgery over the past two decades. There is no consensus between international guidelines. Methods: The Australia and New Zealand Mechanical Bowel Preparation and Oral Antibiotics (ANZ-MBP-OAB) questionnaire was distributed to colorectal surgeons after institutional board approval assessing specialist attitudes toward 18 enhanced recovery after surgery (ERAS) interventions. Data were analyzed using a rating scale and graded response model in item response theory (IRT) on Stata MP, version 15 (StataCorp LP, College Station, TX). Specialist attitudes toward the effectiveness of MBP and OAB strategies in providing better short-term outcomes was ranked alongside other ERAS interventions. This was followed by specific questions examining current practice, perspectives, and trends. Results: Ninety-five of 300 (31.7%) colorectal surgeons in Australia and New Zealand participated in the survey. Statistical modeling was achieved in 13 ERAS interventions. Compared with other ERAS interventions, the use of MBP with OAB and MBP alone ranked nine of 13 and 10 of 13, respectively, in order of effectiveness in providing better short-term outcomes after colorectal surgery. Oral antibiotic agents alone was not considered effective. Mechanical bowel preparation with OAB was considered to be the best strategy in both colon (37%) and rectal surgery (48%) but current practice varied substantially from perspective. Mechanical bowel preparation alone was strongly favored in rectal surgery (81%) with only 14% using MBP with OAB. In colon surgery, only 10% used MBP with OAB, with MBP alone (45%) and no preparation (45%) being equally the most commonly used strategies. Conclusions: Among Australian and New Zealand colorectal surgeons, MBP with OAB was considered the best bowel preparation strategy. However, despite an awareness of its benefits, MBP with OAB has yet to be widely adopted into clinical practice or guidelines in Australia and New Zealand.

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

Studies on the effects of memantine on QT prolongation have yielded conflicting results. For a long time, memantine was reported to be a safe drug without QT prolongation; however, several case studies have reported memantine-induced QT prolongation in Alzheimer’s patients. This study evaluated the relationship between memantine blood levels, and QT interval changes. Over a 2-week period, we orally administered 20 mg of memantine daily to achieve a steady state in 57 healthy Korean subjects. We measured and analyzed the QT interval and blood memantine concentrations simultaneously before and after treatment, as well as 2 weeks after the last dosing. Correlation analysis was done between blood memantine level and QT interval. No serious adverse events occurred during the study period. Repeated dosing of memantine did not show clinically significant QT interval changes after treatment. Regression analysis was performed based on the results; there was no statistical association between memantine blood level and QT prolongation. In conclusion, the results of the present study demonstrated no clinically significant changes in the QT interval with therapeutic blood levels of memantine.

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

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

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.
