ABSTRACT

Since mid-March 2020, a state of emergency was decreed in Portugal due to the COVID-19 pandemic and, consequently, measures were implemented to protect public health, such as social isolation, which will certainly have a notable impact on the mental health of the population, especially in the most vulnerable groups. Positive Mental Health (PMH) is essential to deal with adversity, in this case with the pandemic, and to live better and with greater satisfaction. We consider it relevant to investigate how PMH was used as a resource to deal with the pandemic, depending on the level of vulnerability and sex. A, cross-sectional study was carried out whose the aim was to evaluate the levels of PMH and psychological vulnerability in people with COVOD-19 infection and analyze the association between PMH and psychological vulnerability among men and women.

METHODS: The instruments used were a sociodemographic characterization questionnaire, the Positive Mental Health Questionnaire, and the Psychological Vulnerability Scale (PVS), that were sent and filled out online. A quantitative, cross-sectional, descriptive, and correlational study was carried out.

RESULTS: After analyzing the results, it was found that approximately 50.4% of the respondents (n = 387) had global PMH values that place them in quartile 50. There was also a statistically significant difference between female and male PMH, with women showing greater psychological vulnerability and lower overall PMH.

CONCLUSIONS: We conclude that the women present a greater psychological vulnerability and a lower level of PMH when compared to men.

RELEVANCE TO CLINICAL PRACTICE: Considering the study’s statistically significant results, when we talk about mental health, we should always consider the sex variable as a vulnerability factor, in a pandemic or non-pandemic phase.

ABSTRACT

OBJECTIVE: We assessed the magnitude of disrespect and abuse experienced by women giving birth at public health facilities in Dire Dawa, Eastern Ethiopia.

METHODS: We conducted a facility-based quantitative cross-sectional study in Dire Dawa City Administration from 21 October to 8 December 2020. We used a pre-tested structured questionnaire to interview 555 randomly selected women who gave birth in public health facilities during the study period. Bivariate and multivariate logistic regression analysis was performed in statistical analysis.

RESULTS: Among 555 women, 473 (85.2%) reported having experienced at least one form of disrespect and abuse. Giving birth at a hospital (adjusted odds ratio [AOR] = 4.15; 95% confidence interval [CI], 2.29-7.51) and being attended by male providers (AOR = 3.27; 95% CI, 1.57-6.81), as well as being attended by three or four providers (AOR = 0.44; 95% CI, 0.22-0.88) and delivering at night (AOR = 0.27; 95% CI, 0.15-0.48) were significantly associated with greater or less likelihood, respectively, of disrespect and abuse.

CONCLUSION: We revealed an unacceptable level of disrespect and abuse toward women giving birth at public health facilities. Health care providers must understand the importance of respectful maternity care. The city’s health bureau should conduct provider training and enforce adherence to respectful care.

ABSTRACT

BACKGROUND: Research suggests that geographic location may impact ovarian cancer (OC) outcomes. Insurance status often remains an important predictor of outcomes. The Affordable Care Act was enacted in 2010 to expand access to affordable health insurance. Our objective was to examine spatiotemporal trends in OC treatment non-adherence and disease-specific mortality in California (USA) among women diagnosed with OC.

METHODS: Newly diagnosed epithelial OC cases between 1996-2017 were identified from the California Cancer Registry. Spatiotemporal trends in adherence to treatment guidelines were examined using generalized additive models and OC-specific mortality using Cox proportional hazards additive models. Prediction grids covering California were used to display the odds ratios (ORs) and hazards ratios (HRs) of location, using the median value for the study area as the referent value. Seven overlapping 5-year time periods and two larger ones (pre- and post-2013) were assessed. Analyses were stratified according to stage (early versus advanced), and used P = 0.05 to determine statistical significance.

RESULTS: Statistically significant spatial patterns in treatment non-adherence were observed for every time period examined (P < 0.001). Odds of treatment non-adherence associated with geographic location were highest among women with early-stage OC in southern Los Angeles County during 2014-2017 (OR max : 3.89, Confidence Interval: 1.04-7.61). For women with advanced-stage OC, residing in Northern California was generally associated with lower ORs, while Southern California was associated with higher ORs, with higher odds in the latter time period (OR range 0.53-1.84 in 1996-2012 vs 0.49-2.37 in 2013-2017). Geographic location was not a significant predictor of mortality.

CONCLUSIONS: Residential location was significantly associated with treatment received in California, with spatial patterns varying over time, but not OC-specific mortality. Changes in insurance status over time were accompanied by shifts in population demographics and increased travel distances to receive care.

ABSTRACT

BACKGROUND: Vitamin K antagonists and different direct oral anticoagulants (DOACs) have different renal clearance rates. However, the impact of different stages of chronic renal impairment on the efficacy and safety of warfarin, dabigatran, rivaroxaban, apixaban, and edoxaban in atrial fibrillation (AF) patients remains unclear.

METHODS: This study enrolled AF patients from the Chang Gung Research Database. The study endpoints included thromboembolic events, major/fatal bleeding, gastrointestinal (GI) bleeding and intracranial hemorrhage (ICH). The risks of time to study endpoints between groups were compared using a Cox proportional hazards regression model with adjustment.

RESULTS: This study enrolled 3525 patients with moderate renal impairment (30 ≤ creatinine clearance (CrCl) < 60 mL/min), 2846 patients with mild renal impairment (60 ≤ CrCl < 90 mL/min) and 1153 patients with CrCl ≥ 90 mL/min. Over the 3.3 ± 0.9 years follow-up period, the cumulative thromboembolic events rates and the cumulative event rates of major/fatal bleeding and ICH did not differ among the warfarin and different DOAC groups at different stages of chronic renal impairment. The annual incidences of thromboembolic events, major/fatal bleeding, GI bleeding, and ICH were similar among the warfarin and different DOAC groups at different stages of renal impairment.

CONCLUSION: There did not appear to be major differences in bleeding or thromboembolic risk compared to warfarin in AF patients across a range of degree of renal failure when appropriate dose reductions of the DOACs are made.

ABSTRACT

The experimental design extracts valuable information about the main effects and interactions from the least number of experiments. The current work constructs a solid-state sensor for selective assay of Ondansetron (OND) in pharmaceutical dosage form and plasma samples. During optimization, the Design Expert^® statistical package constructed a custom design of 15 sensors with different recipes. We fed the software with the experimentally observed performance parameters for each sensor (slope, LOQ, correlation coefficient, and selectivity coefficient for sodium ions). The computer software analyzed the results to construct a prediction model for each response. The desirability function was adjusted to optimize the Nernstian slope, minimize the LOQ and selectivity coefficients, and maximize the correlation coefficient (r). The practical responses of the optimized sensor were close to those predicted by the model (slope = 60.23 mV/decade slope, LOQ = 9.09 × 10^-6 M, r = 0.999, sodium selectivity coefficient = 1.09 × 10^-3). The sensor successfully recovered OND spiked to tablets and human plasma samples with mean percentage recoveries of 100.01 ± 1.082 and 98.26 ± 2.227, respectively. Results were statistically comparable to those obtained by the reference chromatographic method. The validated potentiometric method can be used for fast and direct therapeutic drug monitoring of OND co-administered with chemotherapeutic drugs in plasma samples.

ABSTRACT

OBJECTIVE: To evaluate the impact of cardiovascular risk (CVR) on the diagnostic accuracy of the ultrasonographic (US) Halo Score in patients with suspected giant cell arteritis (GCA).

METHODS: Retrospective observational study of patients referred to our US fast track clinic with suspected GCA for a 2-year period. The intima-media thickness (IMT) of cranial and extra-cranial arteries and the Halo Score was determined to assess the extent of vascular inflammation. The European Society of Cardiology Guidelines on CV Disease Prevention were used to define different categories of CVR and patients were classified according to the Systemic Coronary Risk Evaluation (SCORE). The gold standard for GCA diagnosis was clinical confirmation after a 6-month follow-up.

RESULTS: Of the 157 patients included, 47 (29.9%) had GCA after a 6-month follow-up. Extra-cranial artery IMT was significantly higher in patients with high/very high CVR than in those with low/moderate CVR, but only among patients without GCA. Non-GCA patients with high/very high CVR had also a significantly higher Halo Score in contrast with low/moderate CVR [9.38 (5.93) vs 6.16 (5.22); p = 0.007]. The area under the ROC curve of the Halo Score to identify GCA was 0.835 (95% CI 0.756-0.914), slightly greater in patients with low/moderate CVR (0.965 [95% CI 0.911-1]) versus patients with high/very high CVR (0.798 [95% CI 0.702-0.895]). A statistically weak positive correlation was found between the Halo Score and the SCORE (r 0.245; c = 0.002).

CONCLUSIONS: Elevated CVR may influence the diagnostic accuracy of the US Halo Score for GCA. Thus, CVR should be taken into consideration in the US screening for GCA.

ABSTRACT

INTRODUCTION: Food environments are viewed as the interface where individuals interact with the wider food system to procure and/or consume food. Institutional food environment characteristics have been associated with health outcomes including obesity and nutrition-related non-communicable diseases (NR-NCDs) in studies from high-income countries. The objectives of this study were (1) to map and characterise the food-outlets within a Ghanaian university campus; and (2) to assess the healthiness of the food outlets.

METHODS: Data collection was undertaken based on geospatial open-source technologies and the collaborative mapping platform OpenStreetMap using a systematic approach involving three phases: remote mapping, ground-truthing, and food-outlet survey. Spatial analyses were performed using Quantum Geographical Information System (QGIS) and comprised kernel density, buffer, and average nearest neighbour analyses to assess outlet distribution, density, and proximity. A classification system was developed to assess the healthiness of food-outlets within the University foodscape.

RESULTS: Food-outlets were unevenly distributed over the University foodscape, with many outlets clustered closer to student residencies. Informal food-outlets were the most frequent food-outlet type. Compared to NCD-healthy food-outlets, NCD-unhealthy food-outlets dominated the foodscape (50.7% vs 39.9%) with 9.4% being NCD-intermediate, suggesting a less-healthy university foodscape. More NCD-unhealthy food outlets than NCD-healthy food outlets clustered around student residences. This difference was statistically significant for food outlets within a 100-m buffer (p < 0.001) of student residence and those within 100 and 500 m from departmental buildings/lecture halls (at 5% level of significance).

CONCLUSION: Further action, including research to ascertain how the features of the University’s food environment have or are influencing students’ dietary behaviours are needed to inform interventions aimed at creating healthier foodscapes in the study University and other campuses and to lead the way towards the creation of healthy food environments at the home, work, and community levels.

ABSTRACT

BACKGROUND: Stress-induced exhaustion disorder is a major challenge in Swedish working life. Despite its increase in prevalence, there is still limited knowledge about the effectiveness of different rehabilitation methods. In this study, we aim to describe the healthcare utilisation for patients with stress-induced exhaustion disorder before, during and after a multi-modal rehabilitation (MMR) programme, as well as the health-related quality of life, work ability, sick leave level and psychological measures, and their possible relations.

METHODS: In this longitudinal observational study, 53 patients who were part of an MMR programme at the Stress Rehabilitation Clinic participated with survey data, and among them 43 also contributed with healthcare data. Data were collected from one year before start of MMR to one year after the end of it. The patients also answered a questionnaire at the start of, end of and at a one-year follow-up of the MMR, which included questions about health-related quality of life, work ability, clinical burnout, sick leave level, anxiety and depression.

RESULTS: There was a statistically significant increase in healthcare consumption during MMR, if including visits to the Stress Rehabilitation Clinic, while it decreased if excluding such visits, when comparing with before and after MMR. During the follow-up period there was a non-statistically significant (p=0.11), but still rather large difference (15.4 compared with 12.0 visits per patient), in healthcare consumption in comparison with the period before MMR, when excluding follow-up visits at the Stress Rehabilitation Clinic. Health-related quality of life was rated as poor before MMR (mean 0.59). There was a statistically significant improvement, but values were still below normal at the end of follow-up (mean 0.70). In addition, the level of sick leave, the work ability and signs of clinical burnout improved statistically significantly after MMR, but were not fully normalised at the end of follow-up. Individual healthcare consumption was related to residual health problems.

CONCLUSIONS: Patients with stress-induced exhaustion disorder have not reduced their healthcare consumption notably after MMR, and residual health problems remain for some patients. More studies are needed for a deeper understanding of the individual effectiveness of MMR, and also of its cost-effectiveness.

ABSTRACT

BACKGROUND: Professional identity, an important process in the development and expansion of the nursing profession, is built over time and includes gaining insight into professional performances and fostering ideals and values for the profession. Several factors influence the formation of professional identity. This study investigates the level of professional identity in nursing students and its predictors using a localized tool.

METHODS: This cross-sectional study recruited 195 nursing students at Semnan University of Medical Sciences, Semnan, Iran, who were selected by census sampling in 2020. Data were collected using a researcher-made professional identity questionnaire and were then analyzed in SPSS-18 using descriptive and inferential (logistic regression) statistics.

RESULTS: The mean total score of the students’ perceived professional identity was 316.72, indicating a strong professional identity. The students’ professional identity had a significant relationship with variables including GPA above 16 (OR = 2.65, P = 0.002), choosing the field out of interest (OR = 2.15, P = 0.015), and having work experience while studying (OR = 3.10, P = 0.006).

CONCLUSION: The findings showed that selecting the field of nursing out of interest, having a GPA above 16 and work experience while studying are associated with a higher perception of professional identity among nursing students. The professional identity of nursing students can be enhanced through reinforcing the mentioned factors and further attention to their role in the promotion and consolidation of professional identity. The researchers recommend that educational directors, nursing professors, and clinical nursing educators make greater efforts to develop and promote the professional identity of nursing students.
