Door-to-Door Eye Health Education to Improve Knowledge, Attitude, and Uptake of Eyecare Services Among Elderly with Cataracts: A Quasi-Experimental Study in the Central Tropical Region, Myanmar

Introduction Cataract-related blindness is routinely reported globally. This study aimed to measure the effect of door-to-door eye health education in improving knowledge and attitude toward cataracts and the use of eyecare services among the elderly residing in a rural area of Naypyitaw Union Territory, Myanmar. Methods A quasi-experimental study design that used intervention and control groups was employed in Lewe Township from November 2018 to April 2019. Stratified sampling method was used to select lists of patients diagnosed with cataracts via a township-wide prevalence survey of eye diseases. A total of 56 elderly people with cataracts were involved in each group. The intervention group received door-to-door eye health education for 3 consecutive months. The data were collected using pre- and post-intervention surveys. Descriptive statistics for general characteristics as well as Chi-squared tests and multivariate analysis of variance for significant differences between knowledge and attitude scores of the two groups were analyzed. Results Both groups represented similarities in socio-economic characteristics, pre-existing knowledge and attitude levels, and eyecare services use. During the baseline study, the mean knowledge score in the intervention group was 7.8 and after the intervention, it increased to 10.67. Attitude score increased from 4.51 to 7.55. Among the control group, the scores remained unchanged. For use of eyecare services in the intervention group, 35.7% of patients sought eyecare services before the intervention, but after, 85.7% accessed eyecare services. Among them, 78.6% were satisfied with the treatment outcome. Further, there was a significant difference in knowledge and attitude between the control group and the intervention group (p-value <0.05), representing a medium effect of the intervention on improving knowledge and attitude level. Conclusion Door-to-door eyecare education significantly increased knowledge and attitude toward cataracts and the use of eyecare services among the elderly with cataracts. Intervention might be effective in improving the use of eyecare services and reduction of avoidable blindness due to cataracts.
Edge-Rich Interconnected Graphene Mesh Electrode with High Electrochemical Reactivity Applicable for Glucose Detection

The development of graphene structures with controlled edges is greatly desired for understanding heterogeneous electrochemical (EC) transfer and boosting EC applications of graphene-based electrodes. We herein report a facile, scalable, and robust method to produce graphene mesh (GM) electrodes with tailorable edge lengths. Specifically, the GMs were fabricated at 850 °C under a vacuum level of 0.6 Pa using catalytic nickel templates obtained based on a crack lithography. As the edge lengths of the GM electrodes increased from 5.48 to 24.04 m, their electron transfer rates linearly increased from 0.08 to 0.16 cm∙s−1, which are considerably greater than that (0.056 ± 0.007 cm∙s−1) of basal graphene structures (defined as zero edge length electrodes). To illustrate the EC sensing potentiality of the GM, a high-sensitivity glucose detection was conducted on the graphene/Ni hybrid mesh with the longest edge length. At a detection potential of 0.6 V, the edge-rich graphene/Ni hybrid mesh sensor exhibited a wide linear response range from 10.0 μM to 2.5 mM with a limit of detection of 1.8 μM and a high sensitivity of 1118.9 μA∙mM−1∙cm−2. Our findings suggest that edge-rich GMs can be valuable platforms in various graphene applications such as graphene-based EC sensors with controlled and improved performance.
Epitaxial Growth and Characterization of 4H-SiC for Neutron Detection Applications

The purpose of this work is to study the 4H-SiC epitaxial layer properties for the fabrication of a device for neutron detection as an alternative material to diamond detectors used in this field. We have studied a high growth rate process to grow a thick epitaxial layer (250 µm) of 4H-SiC and, in order to estimate the quality of the epitaxial layer, an optical characterization was done through Photoluminescence (PL) spectroscopy for stacking fault defect evaluation. Micro Raman spectroscopy was used for simultaneous determination of both carrier lifetime and induced carriers in equilibrium. We have compared these results with other two samples with an epitaxial layer of 100 micron, obtained with two different growth rates, 60 and 90 µm/h, respectively. From Raman measurements it has been observed that both the growth rate and the grown epitaxial layer thickness have an effect on the measured carrier lifetime. A comparison between different kinds of stacking faults (SF) was done, evaluating the influence of these defects on the carrier lifetime as a function of the injection level and it was observed that only at a low injection is the effect on the carrier lifetime low.
Self-sampling for high-risk human papillomavirus as a follow-up alternative after treatment of high-grade cervical intraepithelial neoplasia

Women treated for high-grade cervical-intraepithelial-neoplasia (CIN) require long-term follow-up with high-risk human-papillomavirus (HPV) testing. Self-sampling for HPV is well-accepted among these patients, but its role in follow-up for this group requires investigation. The present study examined how well HPV findings from self-sampled vaginal (VSS) and urine specimens correctly identified women from this cohort with recurrent CIN2+ compared with samples collected by clinicians. At 1st post-conization follow-up, 531 patients (99.8% participation) gave urine samples, performed VSS, underwent colposcopy with punch biopsy of visible lesions and clinician-collected cervical sampling for HPV analysis and liquid-based cytology. A total of 113 patients with positive HPV and/or abnormal cytology at 1st follow-up underwent 2nd follow-up. At 1st follow-up, all patients with recurrent CIN3 had positive HPV results by all methods. Clinician sampling and VSS revealed HPV16 positivity in 50% of recurrent cases and urine sampling revealed HPV16 positivity in 25% of recurrent cases. At 2nd follow-up, all 7 newly-detected CIN2/3 recurrences were associated with HPV positivity on VSS and clinician-samples. Only clinician-collected samples detected HPV positivity for two adenocarcinoma-in-situ recurrences, and both were HPV18 positive. A total of 77 patients had abnormal cytology at 1st follow-up, for which HPV positivity via VSS yielded highest sensitivity. The HPV findings were positive from VSS in 12 patients with high-grade squamous-intraepithelial-lesions (HSIL), and 11 patients with HSIL had positive HPV findings in clinician-collected and urine samples. All methods for assessing HPV presence yielded significant age-adjusted odds ratios for predicting abnormal lesions at 1st follow-up. For overall HPV results, Cohen's kappa revealed substantial agreement between VSS and clinician sampling, and moderate agreement between urine and clinician sampling. Clinician sampling and VSS were highly concordant for HPV16. Insofar as the pathology was squamous (not glandular), VSS appeared as sensitive as clinician sampling for HPV in predicting outcome among the present cohort. Since VSS can be performed at home, this option can maximize participation in the required long-term follow-up for these women at high-risk.
Sleep Indices and Cardiac Autonomic Activity Responses during an International Tournament in a Youth National Soccer Team

This study aimed to describe habitual sleep and nocturnal cardiac autonomic activity (CAA), and their relationship with training/match load in male youth soccer players during an international tournament. Eighteen elite male youth soccer players (aged 14.8 ± 0.3 years; mean ± SD) participated in the study. Sleep indices were measured using wrist actigraphy, and heart rate (HR) monitors were used to measure CAA during night-sleep throughout 5 consecutive days. Training and match loads were characterized using the session-rating of perceived exertion (s-RPE). During the five nights 8 to 17 players slept less than <8 h and only one to two players had a sleep efficiency <75%. Players’ sleep duration coefficient of variation (CV) ranged between 4 and 17%. Nocturnal heart rate variability (HRV) indices for the time-domain analyses ranged from 3.8 (95% confidence interval, 3.6; 4.0) to 4.1 ln[ms] (3.9; 4.3) and for the frequency-domain analyses ranged from 5.9 (5.6; 6.5) to 6.6 (6.3; 7.4). Time-domain HRV CV ranged from 3 to 10% and frequency-domain HRV ranged from 2 to 12%. A moderate within-subjects correlation was found between s-RPE and sleep duration [r = −0.41 (−0.62; −0.14); p = 0.003]. The present findings suggest that youth soccer players slept less than the recommended during the international tournament, and sleep duration was negatively associated with training/match load.
Is Cycling Practice Related to Men’s Pelvic Floor Dysfunctions? A Hypothesis-Generating Observational Study

Background: There is a lack of consensus with regards to the consequences of cycling practice on urogenital and sexual problems in men. The aim of the study was to analyse the relationship between intensity of cycling practice and urinary tract symptoms, erectile dysfunction, and urinary incontinence. Methods: Observational hypothesis-generating design. Cyclists, men, between 25 and 70 years who had been cycling for more than one year were included. During the statistical analysis, a multiple linear regression model, partial correlation and Spearman’s correlation were carried out. Results: Fifty-eight men participated in the study. Results showed that there is a correlation between years of cycling and prostate symptoms (p = 0.041), and between age and erectile dysfunction (p = 0.001). The multiple linear regression model and the partial correlation analysis showed a correlation between the years of cycling and prostate symptoms (p = 0.007 and p = 0.018). Conclusions: The results have shown that there is a slight correlation between the years of cycling and the presence of lower urinary tract symptoms, independently of the man’s age. Therefore, the results display that high-intensity cycling practice might impact negatively in some men’s pelvic floor functions. Further research is needed to analyse the impact of cycling on urogenital problems in this population group.
Continuous Light Does Not Compromise Growth and Yield in Mini-Cucumber Greenhouse Production with Supplemental LED Light

Continuous lighting (CL, 24 h) can reduce the light intensity/light capital costs used to achieve the desired amount of light for year-round greenhouse vegetable production in comparison to short photoperiods of lighting. However, growth under CL has led to leaf injury characterized by chlorosis unless a thermoperiod or alternating light spectrum during CL is used. To date, there is no literature relating to how cucumbers (Cucumis sativus) respond to CL with LEDs in a full production cycle. Here, we evaluated a mini-cucumber cv. “Bonwell” grown under 4 supplemental lighting strategies: Treatment 1 (T1, the control) was 16 h of combined red light and blue light followed by 8 h of darkness. Treatment 2 (T2) had continuous (24 h) red light and blue light. Treatment 3 (T3) was 16 h of red light followed by 8 h of blue light. Treatment 4 (T4) was 12 h of red light followed by 12 h of blue light. All treatments had a supplemental daily light integral (DLI) of ~10 mol m−2 d−1. Plants from all treatments showed similar growth characteristics throughout the production cycle. However, plants grown under all three CL treatments had higher chlorophyll concentrations from leaves at the top of the canopy when compared to T1. The overall photosynthetic capacity, light use efficiency, and photosynthetic parameters related to light response curves (i.e., dark respiration, light compensation point, quantum yield, and photosynthetic maximum), as well as the quantum yield of photosystem II (PSII; Fv/Fm) were similar among the treatments. Plants grown under all CL treatments produced a similar yield compared to the control treatment (T1). These results indicate that mini-cucumber cv. “Bonwell” is tolerant to CL, and CL is a viable and economical lighting strategy for mini-cucumber production.
Lyophilized Emulsions in the Form of 3D Porous Matrices as a Novel Material for Topical Application

Researchers are constantly searching for innovations that can be applied to the cosmetic industry. Production of porous materials stored in a lyophilized form and swollen directly before use may be beneficial considering their facilitated packaging, transport and storage. In this study, we propose porous materials based on sodium alginate, gelatin, glycerol and lipids (cottonseed oil and beeswax) obtained by freeze-drying and cross-linking. Material composition with the most promising properties was modified by the addition of PLA microparticles with Calendula officinalis flower extract. The structure and properties of obtained porous materials were analyzed. ATR-FTIR, mechanical properties, residual moisture content, porosity and density were assessed, as well as swelling properties and degradation after their cross-linking. The loading capacity and in vitro release of Calendula officinalis flower extract were performed for samples with incorporated PLA microparticles containing plant extract. The modification of the composition and fabrication method of materials significantly influenced their physicochemical properties. The selected plant extract was successfully incorporated into polymeric microparticles that were subsequently added into developed materials. Prepared materials may be considered during designing new cosmetic formulations.
Determinants of Care-Seeking Practices for Children with Sickle Cell Disease in Ekiti, Southwest Nigeria

Background Due to the chronic nature of sickle cell disease (SCD), affected individuals may seek help from diverse places thus raising the need to understand their health-seeking behavior (HSB) in order to design an appropriate management policy for them. Aim The aim of this study was to evaluate the HSB among pediatric SCD patients relative to their non-SCD counterparts attending a tertiary facility in Southwest Nigeria and identified predictors of poor HSB among SCD patients. Methods A total of 110 children with SCD were recruited and studied for their HSPs which were compared with 110 non-SCD patients with other chronic medical conditions. Questionnaires were used to obtain self-reported information on participants’ socio-demographic data and HSB. Logistic regression was used to determine the predictors of poor HSB among the SCD cohort. Results More SCD patients received treatments at private hospitals, patent medicine stores and faith-based centers compared to their non-SCD counterparts (p=0.0052; 0.006; and 0.007), respectively. No difference was observed in the patronage of traditional care centres 10 (9.1%) vs 6 (5.5%). More SCD patients 61 (55.5%) vs 35 (31.8%) exhibited poor HSB (p=0.0004). SCD patients who were not enrolled on health insurance scheme were 18 times more likely to have poor HSB (OR=18.38, 95% CI (4.41–76.57), p value= <0.0001) while absence of VOC within the preceding year reduces the risk of poor HSB by 91.5% (OR=0.085, 95% CI (0.028–0.258), p value= <0.0001). Conclusion SCD patients in the study locality had poor HSB. This raises the need for their education on proper HSB. More enrollment into health insurance scheme and the prevention of VOC will lessen the burden of poor HSB. The high patronage of non-hospital care facilities in this study raises the need for stakeholders to monitor activities and train the operators at these informal care centres.
Imaging Inflammation with Positron Emission Tomography

The impact of inflammation on the outcome of many medical conditions such as cardiovascular diseases, neurological disorders, infections, cancer, and autoimmune diseases has been widely acknowledged. However, in contrast to neurological, oncologic, and cardiovascular disorders, imaging plays a minor role in research and management of inflammation. Imaging can provide insights into individual and temporospatial biology and grade of inflammation which can be of diagnostic, therapeutic, and prognostic value. There is therefore an urgent need to evaluate and understand current approaches and potential applications for imaging of inflammation. This review discusses radiotracers for positron emission tomography (PET) that have been used to image inflammation in cardiovascular diseases and other inflammatory conditions with a special emphasis on radiotracers that have already been successfully applied in clinical settings.
Non-Lethal Sequential Individual Monitoring of Viremia in Relation to DNA Vaccination in Fish–Example Using a Salmon Alphavirus DNA Vaccine in Atlantic Salmon Salmo salar

Traditionally, commercial testing for vaccine efficacy has relied on the mass infection of vaccinated and unvaccinated animals and the comparison of mortality prevalence and incidence. For some infection models where disease does not cause mortality this approach to testing vaccine efficacy is not useful. Additionally, in fish experimental studies on vaccine efficacy and immune response the norm is that several individuals are lethally sampled at sequential timepoints, and results are extrapolated to represent the kinetics of immune and disease parameters of an individual fish over the entire experimental infection period. In the present study we developed a new approach to vaccine testing for viremic viruses in fish by following the same individuals over the course of a DNA vaccination and experimental infection through repeated blood collection and analyses. Injectable DNA vaccines are particularly efficient against viral disease in fish. To date, two DNA vaccines have been authorised for use in fish farming, one in Canada against Infectious Haemorrhagic Necrotic virus and more recently one in Europe against Salmon Pancreatic Disease virus (SPDv) subtype 3. In the current study we engineered and used an experimental DNA vaccine against SPDv subtype 1. We measured viremia using a reporter cell line system and demonstrated that the viremia phase was completely extinguished following DNA vaccination. Differences in viremia infection kinetics between fish in the placebo group could be related to subsequent antibody levels in the individual fish, with higher antibody levels at terminal sampling in fish showing earlier viremia peaks. The results indicate that sequential non-lethal sampling can highlight associations between infection traits and immune responses measured at asynchronous timepoints and, can provide biological explanations for variation in data. Similar to results observed for the SPDv subtype 3 DNA vaccine, the SPDv subtype 1 DNA vaccine also induced an interferon type 1 response after vaccination and provided high protection against SPDv under laboratory conditions when fish were challenged at 7 weeks post-vaccination.
Gastric Carcinomas with Stromal B7-H3 Expression Have Lower Intratumoural CD8+ T Cell Density

CD8+ T cells are the main effector cells of anti-cancer immune response that can be regulated by various costimulatory and coinhibitory molecules, including members of the B7 family. B7 homolog 3 (B7-H3) appears as a promising marker for immunotherapy; however, its significance in gastric cancer (GC) is unclear yet. We evaluated the spatial distribution of CD8+ T cells in relation to the expression of B7-H3 by double immunohistochemical staining. The level of B7-H3 intensity was scored manually (0–3) and dichotomized into B7-H3-low and B7-H3-high groups. The distribution and density of CD8+ T cells was analysed using whole slide digital imaging. B7-H3 was expressed mainly in the stromal compartment of GC (n = 73, 76% of all cases). Tumours with high expression of B7-H3 showed larger spatial differences of CD8+ T cells (86.4/mm2 in tumour centre vs. 414.9/mm2 in invasive front) when compared to B7-H3-low group (157.7/mm2 vs. 218.7/mm2, respectively) (p < 0.001). This study provides insight into the expression pattern of B7-H3 in GC of Western origin. In GCs with higher level of B7-H3 expression, CD8+ T cells were spatially suppressed in the tumour centre suggesting that B7-H3 might be involved in tumour escape mechanisms from the immune response.
The first mitochondrial genome of Parastratiosphecomyia (Diptera: Stratiomyidae)

Abstract The complete mitochondrial genome of Parastratiosphecomyia szechuanensis Lindner, 1954 was sequenced and analyzed in this study. The mitochondrial genome is 16,414 bp in length, including the 37 typical insect mitochondrial genes and a large control region. All PCGs end with complete termination codon TAA or TAG. Most PCGs initiated by standard start codon ATN, except for cox1 which starts with TCG. The phylogenetic analysis based on the nucleotide sequence data of 13 PCGs recovered the monophyly of Stratiomyidae and the sister relationship between Xylomyidae and Stratiomyidae.
Tobacco and E-Cigarettes Point of Sale Advertising—Assessing Compliance with Tobacco Advertising, Promotion and Sponsorship Bans in Poland

The objective of this study was to evaluate compliance with the ban on tobacco and e-cigarette products advertising at point of sale (POS) before and after amendment of the Polish Tobacco Control Act. Data were collected, using an observation checklist, between March and October 2014 (n = 1450 POS) and between March and October 2019 (n = 1320 POS). Ban on tobacco and e-cigarette advertising at POS is commonly violated in Poland. In all POS, at least one form (including tobacco products display) of tobacco advertising was found in 2014 and in 2019. The most common types of tobacco advertising in 2014 were change and counter mats (61%, 42%), posters (38%) and illuminated banners (37%). In 2019, a decrease in promoting tobacco products in the form of mats (p ≤ 0.001), posters and boards (p < 0.001) but an increase in video screens were observed (from 8% in 2014 to 30% in 2019; p < 0.001). A significant increase in the presence of any e-cigarette ads, including e-cigarette displays, illuminated banners and video screens, was observed in 2019 as compared to 2014 (90% vs. 30%; 89% vs. 20%; 31% vs. 2%; 31% vs. 0.5%; p < 0.001). The minimum age or a no-sale-to-minors signs for tobacco and e-cigarettes were not sufficiently placed in POS to comply with the Act. Poor enforcement of the ban on tobacco and e-cigarette ads at POS provides the tobacco industry with an opportunity to promote their products using unlawful ways. There is a need to educate the public, retailers and civil society with respect to their legal responsibilities and roles.
