ABSTRACT

BACKGROUND: Globally, the estimated annual number of new cases of curable sexually transmitted infections occurring among young people aged 15-24 years is approximately 178.5 million. There are fragmented and inconsistent findings on preventive practices for sexually transmitted infections. Thus, this systematic review and meta-analysis protocol aimed to estimate the pooled prevalence of preventive practices of sexually transmitted infections and identify its determinants among young people in Ethiopia.

METHODS: The Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) will be used to develop the review protocol. Online databases such as PubMed, CINAHL, Scopus, Google, and Google Scholar will be used to search published and unpublished studies. The Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument will be used to assess the quality of the study. Statistical heterogeneity will be checked using the Cochran Q test and I2 statistics. Subgroup analysis and meta-regression will be performed to identify the sources of heterogeneity. The statistical analysis will be performed using STATA version 14 software. A random-effects model will be performed to estimate the pooled prevalence and identify determinants of preventive practices of sexually transmitted infections.

DISCUSSION: Young people have a high unmet need for sexual and reproductive health services and poor preventive practices toward sexually transmitted infections. Although there are studies on preventive practices for sexually transmitted infections, there is no study finding on the pooled prevalence of preventive practices for sexually transmitted infections and its determinants among young people in Ethiopia. Thus, this systematic review and meta-analysis protocol will help to develop appropriate strategies.

ABSTRACT

OBJECTIVE: Studies have demonstrated a potential correlation between low vitamin D status and both an increased risk of infection with SARS-CoV-2 and poorer clinical outcomes. This retrospective study examines if, and to what degree, a relationship exists between pre-infection serum 25-hydroxyvitamin D (25(OH)D) level and disease severity and mortality due to SARS-CoV-2.

PARTICIPANTS: The records of individuals admitted between April 7th, 2020 and February 4th, 2021 to the Galilee Medical Center (GMC) in Nahariya, Israel, with positive polymerase chain reaction (PCR) tests for SARS-CoV-2 (COVID-19) were searched for historical 25(OH)D levels measured 14 to 730 days prior to the positive PCR test.

DESIGN: Patients admitted to GMC with COVID-19 were categorized according to disease severity and level of 25(OH)D. An association between pre-infection 25(OH)D levels, divided between four categories (deficient, insufficient, adequate, and high-normal), and COVID-19 severity was ascertained utilizing a multivariable regression analysis. To isolate the possible influence of the sinusoidal pattern of seasonal 25(OH)D changes throughout the year, a cosinor model was used.

RESULTS: Of 1176 patients admitted, 253 had records of a 25(OH)D level prior to COVID-19 infection. A lower vitamin D status was more common in patients with the severe or critical disease (<20 ng/mL [87.4%]) than in individuals with mild or moderate disease (<20 ng/mL [34.3%] p < 0.001). Patients with vitamin D deficiency (<20 ng/mL) were 14 times more likely to have severe or critical disease than patients with 25(OH)D ≥40 ng/mL (odds ratio [OR], 14; 95% confidence interval [CI], 4 to 51; p < 0.001).

CONCLUSIONS: Among hospitalized COVID-19 patients, pre-infection deficiency of vitamin D was associated with increased disease severity and mortality.

ABSTRACT

This study assesses the practices and views of Scottish dairy farmers relating to pasture-based and indoor systems. There are the debates about the environmental, economic and animal welfare implications of these systems. Indoor dairy farming is a contentious practice among the public. While this controversy is sometimes represented as a lack of public understanding, there is a need for more research on farmers’ views to facilitate discussion in the industry. A survey was posted to 909 dairy farmers in Scotland with questions about their grazing practices and attitudes to grazing and indoor systems. 254 surveys were completed, online and in paper form. There was a 26% response rate to the paper version of the survey. The results showed that 19% of respondents housed some or all the cows all year-round. 68% agreed or strongly agreed that cows should graze for part of the year and 51% agreed or strongly agreed that welfare was better if cows grazed for part of the year. These views coexisted with the view that management was more important than the type of system for determining profitability or welfare outcomes (83% and 82% strongly agree or agree respectively). Respondents whose system involved grazing and respondents who had spent longer in farming were moderately more likely to agree that cows should have access to pasture, and slightly less likely to agree that management was more important than system for determining welfare outcomes. The results indicate that the picture is more complicated than the public rejecting indoor dairy farming and those in the industry accepting it. The results showed that a majority preference for cows to graze co-existed with the view that management was more important than system. In terms of industry and policy recommendations, the research suggests that measures should be taken to safeguard farmers’ ability to graze through for instance research and advisory support on grazing; ensuring different systems are not penalised in the development of dairy sector environmental measures and recommendations; and potentially supply chains that financially rewards farmers for grazing.

ABSTRACT

INTRODUCTION: Psychotic illness, although is rare, has been reported in the perinatal period. Individuals diagnosed with psychotic illness tend to first exhibit psychotic-like experiences (PLEs), defined as subclinical psychotic symptoms that occur outside the context of sleep or drug use. However, there is a paucity of empirical data on PLEs in pregnancy to advance scholarly discourse and support professional practice. The current study investigated the prevalence and correlates of PLEs among pregnant women in Ghana, a West African state.

DESIGN: A cross-sectional survey design was used to collect data from 702 pregnant women who responded to measures of PLEs, COVID-19 concerns and behavioral maladies such as anxiety and depressive symptoms. Descriptive and inferential statistics, namely chi square, exploratory factor analysis, MANOVA and multinomial logistic regression were used to analyze the data.

RESULTS: The results showed that 54.2%, 27.3% and 18.5% of participants were at no/low, moderate and high risk for psychosis, respectively. A total of 44.4% participants were not distressed by PLEs, whereas 32.2% and 23.4% were a bit/quite and very distressed, respectively. Psychosis risk was elevated among pregnant women who were more concerned about the COVID-19 effects, scored high in suicidal ideation, depressive symptoms and sleep difficulties.

CONCLUSION: The study showed that psychosis risk is present in pregnancy.

IMPLICATIONS: Screening for psychosis risk in pregnancy should be prioritized for pregnant women with behavioral maladies, including suicidal tendencies, depressive symptoms, sleep difficulties and heightened concerns about COVID-19.

ABSTRACT

On the basis of numerous fluid simulation experiences, researchers have discovered that many common operations can be abstracted to form a general fluid simulation framework. These operations include the discretization of equations and variables, the computation of the coefficients, the assembly of the linear or nonlinear systems, the solving of the systems, etc. Furthermore, all of the operations can be attributed to the operations “in the field”, which is an abstract concept derived from the equations and variables. Thus, fluid simulations can be performed under a field-based general framework. Moreover, in response to the urgent need for large-scale fluid simulations, parallelism is integrated into the framework. Due to the convenience of the field operations, parallelization of the framework can be realized on both the OpenMP and MPI levels. In other words, because of the newly defined “fields”, a series of operations in fluid simulations can be simplified and unified. However, very few studies have noted this advantage, and therefore, this work attempts to fill the void. With the help of a field-based general framework, it is anticipated that the parallel codes of fluid simulations can be generated easily and quickly. As an application of the general framework, a parallel 3D simulator for matrix acidization called Masor is developed. The simulation results are regarded as physically reasonable by many studies, which verifies the correctness and effectiveness of the general framework. In addition, it is noteworthy that the parallel performance of Masor is decided by a solver.

ABSTRACT

BACKGROUND: The variations in ABO blood groups are reported to be associated with multiple disorders, including ulcerative colitis (UC). We aimed to investigate the distribution of ABO blood groups in UC patients and explore its impact on disease severity.

METHODS: We retrospectively collected 129 UC patients diagnosed at our hospital between January 2000 and November 2019. Clinical characteristics, ABO blood groups, and operation rates were analyzed.

RESULTS: The mean diagnostic age of patients was 38.97 years. Males accounted for the majority of all patients (62.8%). Of 129 patients, 43 (33.3%) were blood type O, 41 (31.8%) were blood type A, 38 (29.5%) were blood type B, and 7 (5.4%) were blood type AB. Although our patients had higher ratio of blood type A comparing our general population, there was no statistically significant association of ABO blood types distribution between these two groups (p = 0.1906). In the subgroup analysis, there were no significant difference of disease locations and operation rates between different ABO blood groups. Furthermore, blood type A patients had higher serum hemoglobin (Hb) levels compared to blood type O patients (13.31 g/dL vs. 12.30 g/dL, p = 0.0347). Blood type A patients had lower serum erythrocyte sedimentation rate (ESR) levels compared to blood type O patients (12.46 mm/hour vs. 21.5 mm/hour, p = 0.0288). Blood type O had higher serum ESR levels compared to non-O groups (p = 0.0228). In the ABO blood groups and mean diagnostic age (≤ 40 years or > 40 years), there were no statistically significant difference between these two age groups, p = 0.5515.

CONCLUSIONS: Our results showed ABO blood groups are not associated with UC in spite of a higher ratio of blood type A in our patients. Blood type O patients had higher serum ESR levels; however, blood type A patients had higher Hb levels.

ABSTRACT

BACKGROUND: Percutaneous endovascular aneurysm repair (PEVAR) is becoming increasingly popular due to fewer access-related complications, shorter procedural times and length of stay (LOS). Our aim was to explore factors associated with access-related complications and their impact on procedural time and LOS.

METHODS: We retrospectively analysed consecutive aorto-iliac endovascular procedures in a tertiary hub comprising 2 institutions and 18 consultant vascular surgeons and interventional radiologists between 2016 – 2017. Access-related complications were defined as: bleeding requiring cutdown or return to theatre, acute limb ischaemia or common femoral artery (CFA) pseudoaneurysm requiring intervention and wound infection or dehiscence needing hospitalization.

RESULTS: Of 511 patients, 354 (69%) had a percutaneous approach via 589 CFA access sites. In this percutaneous group, access-related complications occurred in 11% of sites (65/589); Their rate varied with procedure type ranging between 3.6% to 17.6%. The most common complication was bleeding due to closure device failure in 8.5% (50/589) of access sites. When uncomplicated, percutaneous interventions were faster compared to open surgical access (p<0.0001). Operation time and median LOS (3 vs. 2 days) were longer for elective standard EVAR patients experiencing access-related complications (p=0.033). In the percutaneous group, multivariate regression analysis demonstrated significant associations between accessrelated complications and eGFR (odds ratio (OR) 0.984 [0.972-0.997], p=0.014), CFA depth (OR 1.026 [1.008-1.045], p=0.005), device used (Prostar vs. Proglide (OR 2.177 [1.236-3.832], p=0.007) and procedural type (complex vs. standard EVAR) (OR 2.017 [1.122-3.627], p=0.019). We developed a risk score which had reasonably good predictive power (C-statistic 0.716 [0.646-0.787],p<0.0001) for avoiding access complications.

CONCLUSIONS: Physiological (low eGFR level), anatomical (increased CFA depth) and technical factors (choice of device and complex procedures) were identified as predictors of access-related complications in this large retrospective series. These are important for safe selection of patients that would benefit from percutaneous access.

ABSTRACT

BACKGROUND: Hospitalisation provides an opportunity for medication review and deprescribing. Patient-reported experience measures (PREM) for deprescribing in older patients in-hospital are not well-described.

AIM: To pilot test and describe PREM for deprescribing in older patients, compare PREM by patient characteristics, and investigate patients’ awareness of medication changes on hospital discharge.

METHODS: This prospective, multicentre, observational cohort study at two tertiary hospitals in Sydney, Australia, evaluated the PREM questionnaire developed by the NSW Therapeutic Advisory Group. It was completed by patients (or their next of kin) recruited from acute geriatric medicine and orthogeriatric services. Association with nine patient characteristics was analysed using the chi-square test and multivariable regression. Awareness of medication changes and test-retest reliability were analysed using descriptive statistics.

RESULTS: Overall, 201 participants completed the questionnaire, with 170 eligible for analysis; 34/170 (20%) were aware of reduction or cessation of their usual medications on discharge and reported involvement in decision making and receiving enough information to reduce or stop one or more of their usual medications (positive PREM). Independent predictors of positive PREM included respondent (next of kin), hospital (Hospital 1), language (English), and specialty (acute geriatric medicine). Overall, 92 of 155 (59.4%) patients with medication changes were aware of those changes on hospital discharge.

CONCLUSIONS: These PREMs are a feasible tool to examine older patients’ experiences of deprescribing in-hospital and may be applied to evaluate interventions to improve awareness, shared decision making, and provision of information when deprescribing for older patients.

ABSTRACT

BACKGROUND: The experiment tested the effect of non-contact boxing training on the frequency and timing of anticipatory postural adjustments (APAs) resulting from self-induced postural perturbations in healthy adults.

METHODS: The 8-week non-contact boxing intervention study involved 33 healthy adults between 18 and 27 years of age who had no boxing experience (control group = 17 participants, boxing group = 16 participants). Pretests and posttests utilized rapid bilateral arm raising as a focal movement to elicit APAs. EMG in the anterior deltoid, thoracic and lumbar erector spinae, semitendinosus and soleus muscles was recorded. The boxing group completed twenty 90-min non-contact boxing training sessions over 8 weeks, whereas the control group kept physical activity consistent during the intervention period.

RESULTS: Non-contact boxing training caused APAs to become more frequent during the focal movement, in comparison to the control group, in the soleus and also in the semitendinosus after an outlier was removed. Non-contact boxing training caused earlier APA onset during the focal movement, in comparison to the control group, in the lumbar erector spinae after an outlier was removed.

CONCLUSIONS: Non-contact boxing training had a modest positive effect on the frequency and timing of APAs resulting from self-induced postural perturbations in healthy adults.
