Authors: Wijata Aleksandra , Wydeheft Lidia , Janiak Michał , Fronc Kamila , Kędziora-Kornatowska Kornelia 
Published: April 2022

Introduction: Obstructive Sleep Apnea is a disease entity that affects many aspects of life, but is often overlooked and underdiagnosed. OSA is defined as episodes of apnea-hypopnea that disturbs not only sleep, but also daytime functioning. Symptoms can be divided into night symptoms (not breathing, snoring, gasping, fragmented sleep) and daytime symptoms (fatigue, low concentration, morning headaches, decreased libido). Moreover, OSA through many mechanisms affects the cardiovascular system and leads to its dysfunction.
Purpose: The aim of this study is to draw attention to the often underdiagnosed disease entity, which is OSA, which, if left untreated, may lead to serious complications.
Material and methods: In 2022, the PubMed and Google Scholar databases were searched using the following keywords: OSA, apnea, cardiovascular disorders, arrhythmias and heart disease. Works in English with the most recent data have been selected.
Summary: OSA is strongly associated with cardiovascular disorders, moreover, in both cases, we find similar risk factors for these disorders. A correlation has been demonstrated between OSA and atrial fibrillation, hypertension, and arrhythmias. On the other hand, OSA is still underdiagnosed and more research is needed to understand the correlation between these diseases.

Published: April 2022

Oxygen is a gas essential to human life and industrial processes. Here, we developed a highly sensitive oxygen gas sensor based on deep ultraviolet absorption spectroscopy between 180 and 200 nm. The implemented method relies on differential absorption spectra extracted from the obtained high-resolution absorption spectra. The detection capability was greatly improved (six-fold) by eliminating air from the open optical path, achieved by purging the entire system with pure nitrogen. A linear relationship was obtained between the optical parameter and the oxygen concentration with a slope of 0.107 and determination coefficient of 0.999. A detection limit of 24 ppm per meter was determined with a response time of 25 s. Good repeatability (

In this paper, a hybrid vanadium dioxide (

)-graphene-based bifunctional metamaterial is proposed. The realization of the different functions of perfect transmission and high absorption is based on the insulator-metal phase transition of

material. The Fermi energy level of graphene can be treated to dynamically tune the absorption and transmission rates of the metamaterial structure. As a result, when

is in the insulating state, the designed metamaterial can be used as a filter providing three adjustable passbands with center frequencies of 1.892 THz, 1.124 THz, and 0.94 THz, and the corresponding transmittances reach 93.11%, 98.62%, and 90.01%, respectively. The filter also shows good stopband characteristics and exhibits good sensing performance at the resonant frequencies of 1.992 THz and 2.276 THz. When

is in metal state, the metamaterial structure acts as a double-band absorber, with three absorption peaks (

) in the range of 0.684 THz to 0.924 THz, 2.86 THz to 3.04 THz, and 3.28 THz to 3.372 THz, respectively. The designed structure is insensitive to the polarization of vertically incident terahertz waves and still maintains good absorption performances over a large range of incidence angles. Finally, the effects of geometric parameters on the absorption and transmission properties of the hybrid bifunctional metamaterials have also been discussed. The switchable metamaterial structures proposed in this paper provide great potential in terahertz application fields, such as filtering, smart sensing, switching, tunable absorbers, and so on.

Introduction
Impacts of COVID-19 mitigation measures on seasonal respiratory viruses is unknown in sub-tropical climates.

Methods
We compared weekly testing and test-positivity of respiratory infections in the 2019–2020 respiratory season to the 2012–2018 seasons in southern Puerto Rico using Wilcoxon signed rank tests.

Results
Compared to the average for the 2012–2018 seasons, test-positivity was significantly lower for Influenza A (p<0.001) & B (p<0.001), respiratory syncytial virus (RSV) (p<0.01), respiratory adenovirus (AdV) (p<0.05), and other respiratory viruses (p<0.001) following March 2020 COVID-19 stay at home orders.

Conclusions
Mitigation measures and behavioral social distancing choices may have reduced respiratory viral spread in southern Puerto Rico.
How do traditional media access and mobile phone use affect maternal healthcare service use in Bangladesh? Moderated mediation effects of socioeconomic factors
Authors: Kabir Md Ruhul 
Published: April 2022

Background
Exposure to traditional media (TV, radio, and newspapers) and the use of mobile as an interpersonal communication tool allow for a variety of information provision. The purpose of this study is to investigate how women’s media and mobile access affect maternal health service (MHS) utilization. The study also aims to look into the moderated mediation effects of socioeconomic variables on the association mentioned above.

Methods
The study analyzed reproductive and media data of 5,011 ever-married women extracted from the latest nationally representative Bangladesh Demographic and Health Survey. Hierarchical logistic regression and moderated mediation analysis are performed to determine the association.

Results
Only 26.9% of women used mobile for health service use, while more than 55% had media access. Media access is significantly associated with all three types of MHS use; mobile usage also has a significant association with antenatal and delivery care. When women have both access to media and mobile, the likelihood of delivering in a health facility increased by 1.82 times (AOR: 1.82, 95%CI: 1.51, 2.20) which is slightly better than having access to only one type of media channel. Women’s education, household wealth, place of residence, religion, and current working status are among the socioeconomic factors associated with access to media and mobile. Women’s education mediates the relationship of media and MHS; however, the mediation effect of women (β: .45; LLCI: .21, ULCI: .68) on the association of media and place of delivery is seen to be moderated by household wealth. Women who belong to well-off families moderates positively (Effect: .33, 95%CI: .27, .40) the education effect of media and where to deliver. Place of residence, another moderator, significantly moderates (Effect: .09, BootLLCI: .02, BootULCI: .16) the mediation effect of women’s education on the association of media and antenatal care visits; women living in urban areas seems to have positively moderated the education effects on the mentioned association.

Conclusions
Provision of media access and mobile use indicate better utilization of MHS in Bangladesh, and women’s education mediates these relationships via the influence of household wealth and area of residence. Therefore, while planning interventions to increase MHS use, its relationships with the media and mobile use should be extrapolated. The collective use of these channels could be a catalyst for the success of health promotion initiatives to improve women’s health behaviors, build community capacity, and create mass awareness that supports the optimal use of MHS in Bangladesh.
Breastfeeding practice and factors associated with exclusive breastfeeding among mothers in Horro District, Ethiopia: A community-based cross-sectional study
Authors: Jebena Debela Daba , Tenagashaw Mesfin Wogayehu 
Published: April 2022

Background
Breastfeeding is the process of feeding a newborn with the mother’s milk, and it is very important for enhancing child and maternal health. The proportion and duration of breastfeeding may vary by location, and is poorly practiced for cultural, economic, and societal reasons. Thus, this study was conducted to determine breastfeeding practices and determinants of exclusive breastfeeding among mothers of six month aged infants in the Horro district, Ethiopia.

Methods
We used a community-based cross-sectional study among 649 mothers of index infants. A multi-stage sampling procedure was used to select the women. Data were collected from March 15 to April 5, 2020. Face-to-face interviews were used to collect data using a semi-structured questionnaire. Bivariable and multivariable logistic regression were performed to examine the factors associated with exclusive breastfeeding.

Results
All women who participated in the study have ever breastfed their children at some point. Exclusive breastfeeding and breastfeeding initiation were found to be good (70.4% and 61.8%, respectively) within 24 hours prior to the survey time. Having had information about breastfeeding during antenatal care (AOR = 4.15, 95% CI = 2.36, 7.30), postnatal care follow-up (AOR = 4.74, 95% CI = 2.92, 7.70), having infant aged 0-1month (AOR = 12.14, 95% CI = 3.83, 38.46) and 2–3 month (AOR = 8.62, 95% CI = 5.00, 14.85), being a single birth (AOR = 12.91, 95% CI = 3.86, 43.21), having monthly income of ≤ 100 Ethiopian Birrs (AOR = 1.96, 95% CI = 1.16, 3.32), and breastfeeding initiation within one hour of birth (AOR = 1.94, 95% CI = 1.13, 3.35) were found to be a significantly associated factors of exclusive breastfeeding.

Conclusion
Despite meeting the global nutrition target of 2025, the practice of exclusive breastfeeding was lower than the WHO recommendations. Providing education about breastfeeding during antenatal care follow-up and increasing access to postnatal care follow-up is recommended to enhance exclusive breastfeeding practices in the study area.

Published: April 2022

Introduction
Inherent differences as well as health disparities among rural and urban populations warrant further studies focused on the characteristics and outcomes in COVID-19 patients in a rural setting. The aim of this study was to describe these elements in patients infected with SARS-CoV2, hospitalized at a single center in rural Pennsylvania.

Methods
Patients with SARS-CoV2 infections hospitalized between March-December 2020 were studied. Data were obtained from electronic health records generated reports and was retrospectively analyzed. Patients were classified into three groups according to severity. Distribution of variables was studied among these three groups. Using certain variables, we ran logistic regression analysis to study the odds of death and requirement of mechanical ventilation (MV).

Results
Among 335 hospitalized patients infected with SARS-CoV2, age more than 65 years increased the severity of clinical status and in-hospital mortality. Gender did not affect odds of death nor need for MV. Hypertension was the most common comorbidity, but diabetes mellitus and chronic obstructive pulmonary disease (COPD) increased the risk of death. In terms of laboratory parameters, our data suggests that maximum LDH marginally increased the risk of death and maximum WBC marginally increased the risk of need for MV and death.

Conclusion
Through our basic analysis of various characteristics of SARS-CoV2 positive patients admitted in a rural hospital, we have identified certain risk factors associated with severe disease and increased in-hospital mortality. These were found to be largely similar to current literature from studies in urban populations, bolstering the reproducibility and generalizability of existing knowledge. This information lays the foundation for future studies to investigate the role of these factors in morbidity and mortality associated with COVID-19 in depth.

Authors: Song Do Kyeong , Hong Young Sun , Sung Yeon-Ah , Lee Hyejin 
Published: April 2022

Background
Obesity is associated with cardiovascular diseases and is a risk factor for all-cause mortality. Until now, the associations between abdominal obesity and mortality or cardiovascular disease (CVD) incidence have not been conclusive. We aimed to evaluate the associations between waist circumference (WC) and mortality or CVD incidence in a general Korean population.

Methods
We analyzed a total of 204,068 adults older than 40 years of age who had undergone a national health examination at least once from 2009 to 2018 in the Korean National Health Insurance Service Cohort. WC was divided into five categories (< 80, 80–84.9, 85–89.9, 90–94.9, ≥ 95 cm). Hazard ratios for death and CVD incidence were calculated using Cox proportional hazards models.

Results
In men, WC and overall mortality showed a reverse J-shaped association. In women, the association between WC and overall mortality was not significant. For both men and women, WC was not associated with the risk of cardiovascular mortality. Contrary to the mortality trend, CVD incidence was positively associated with WC in both men and women, and the risk of the CVD incidence was the lowest in subjects with a WC < 80 cm.

Conclusions
WC exhibited a significant J-shaped association with overall mortality in men, where subjects who had central obesity showed a lower rate of mortality than those in the lowest or highest WC group. The risk of incident CVD showed a positive association with central obesity, where the lowest risk was observed for subjects in the lowest WC group in a general Korean population.

Background: Virtual education today is about to become one of the most important educational methods in nursing. However, there have been few studies that have examined the effectiveness of virtual education to increase knowledge towards breast cancer among nurses in Iran.Purpose: The aim of this study was to compare the knowledge towards breast cancer among nurses who were provided with two different methods of virtual training. Methods: This quasi-experimental study was conducted among 182 nurses in two hospitals in Tehran, Iran, who were randomly selected and divided into two groups of 91 nurses. Participants of the first group got virtual training about breast cancer in two sessions within two weeks by Skyroom. In the second group, the content was sent as educational messages by WhatsApp within two weeks. Participants’ knowledge in both groups was measured using valid and reliable questionnaires developed by the researchers as a pretest and three posttests, and the satisfaction of the participants was also measured. To analyze the data, analysis of variance, standard deviation, t-test and Tukey test were performed.Results: According to the average score observed in the post-test period, the score of the WhatsApp group was 7.62, significantly higher than the Skyroom group of 6.25. The scores of the three post-test were higher than the pre-test in the two groups (with no significant difference between the two groups, p-value = 0.825 in the first post-test), but the scores declined from the first to third tests, showing a decline in the learning effect with time. However, the slope was gentler in the WhatsApp group, showing a more persistent learning effect.Conclusion: This study showed that teaching with educational messages through WhatsApp had a greater impact on the sustainability of learning than teaching via lecturing through Skyroom.

Abstract

Objectives
Infection by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19) presents occasionally with an aberrant autoinflammatory response, including the presence of elevated circulating autoantibodies in some individuals. Whether the development of autoantibodies against self-antigens affects COVID-19 outcomes remains unclear. To better understand the prognostic role of autoantibodies in COVID-19, we quantified autoantibodies against 23 markers that are used for diagnosis of autoimmune disease. To this end, we used serum samples from patients with severe [intensive care unit (ICU)] and moderate (ward) COVID-19, across two to six consecutive time points, and compared autoantibody levels to uninfected healthy and ICU controls.

Methods
Acute and post-acute serum (from 1 to 26 ICU days) was collected from 18 ICU COVID-19-positive patients at three to six time points; 18 ICU COVID-19-negative patients (sampled on ICU day 1 and 3); 21 ward COVID-19-positive patients (sampled on hospital day 1 and 3); and from 59 healthy uninfected controls deriving from two cohorts. Levels of IgG autoantibodies against 23 autoantigens, commonly used for autoimmune disease diagnosis, were measured in serum samples using MSD® U-PLEX electrochemiluminescence technology (MSD division Meso Scale Discovery®), and results were compared between groups.

Results
There were no significant elevations of autoantibodies for any of the markers tested in patients with severe COVID-19.

Conclusions
Sample collections at longer time points should be considered in future studies, for assessing the possible development of autoantibody responses following infection with SARS-CoV-2.
On tempered representations
Authors: Kazhdan David , Yom Din Alexander 
Published: April 2022

Abstract
Let G be a unimodular locally compact group. We define a property of irreducible unitary G-representations V which we call c-temperedness, and which for the trivial V boils down to Følner’s condition (equivalent to the trivial V being tempered, i.e. to G being amenable). The property of c-temperedness is a-priori stronger than the property of temperedness.
We conjecture that for semisimple groups over local fields temperedness implies c-temperedness. We check the conjecture for a special class of tempered V’s, as well as for all tempered V’s in the cases of

G
:=

SL

⁢

{G:=\mathrm{SL}_{2}({\mathbb{R}})}

and of

G
=

PGL
2

⁢

(
Ω
)

{G=\mathrm{PGL}_{2}(\Omega)}

for a non-Archimedean local field Ω of characteristic 0 and residual characteristic not 2. We also establish a weaker form of the conjecture, involving only K-finite vectors.
In the non-Archimedean case, we give a formula expressing the character of a tempered V as an appropriately-weighted conjugation-average of a matrix coefficient of V, generalising a formula of Harish-Chandra from the case when V is square-integrable.
The role of natural rubber endogenous proteins in promoting the formation of vulcanization networks
Authors: Liu Xiu-Xiu , He Meng-Fan , Luo Ming-Chao , Wei Yan-Chan , Liao Shuangquan 
Published: April 2022

Abstract
Non-rubber components are critical in the formation of the natural rubber (NR) vulcanization network, which leads to outstanding mechanical properties of NR. This study reports the effect of NR endogenous proteins (C-serum protein/lutoid protein [CSP/LP]) on the formation of vulcanization networks at the molecular level. Results indicate that CSP/LP has a positive effect on vulcanization. Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy analyses demonstrate that the decrease in vulcanization time of CSP/LP is ascribed to coordination interaction between Zn2+ and amide bond. The interaction increases the availability of ZnO in the matrix, thereby promoting the formation of the vulcanized network. CSP/LP also participates in the construction of the vulcanization network as a new crosslinking point, thus increasing crosslinking density and improving the mechanical properties of the NR. This study provides new research ideas for studying the relationship among component–structure–property of NR materials and developing high-strength and high-toughness elastomer materials.
