UV-Vis Higher-Order Derivative Spectra Disclose the Involvement of Two Processes in the Solid-State 4+4 Photocycloaddition of an Amorphous Bisanthracene
Authors: Ichimura Kunihiro , Sonoda Taishi , Ubukata Takashi 
Published: April 2022

Abstract
UV-induced solid-state oligomerization of an amorphous bisanthracene in films was determined by UV-Vis even-order derivative spectra to reveal the involvement of fast and slow photocycloaddition processes due to the difference in the level of π,π-interactions and the marked enhancement of the photoreaction above glass transition temperature.

Background: Anaemia affects more than half of Africa’s pregnancies. Standard care, with oral iron tablets, often fails to achieve results, with compliance and gastrointestinal side-effects being a significant issue. In recent years, intravenous iron formulations have become safe, effective, and quick to administer, allowing the complete iron requirements of pregnancy to be provided in one 15-minute infusion. The Randomized controlled trial of the Effect of intraVenous iron on Anaemia in Malawian Pregnant women (REVAMP) will evaluate whether a modern intravenous iron formulation, ferric carboxymaltose (FCM), given once during the second trimester is effective and safe in improving maternal and neonatal outcomes for treatment of moderate to severe anaemia in sub-Saharan Africa. The objective was to publish the detailed statistical analysis plan for the REVAMP trial prior to unblinding the allocated treatments and performing the analysis. Methods: REVAMP is a multicentre, two-arm, open-label, parallel-group randomized control trial (RCT) in 862 pregnant women in their second trimester. The trial statistician developed the statistical analysis plan in consultation with the trial management team based on the protocol, data collection forms, and study outcomes available in the blinded study database. Results: The detailed statistical analysis plan will support the statistical analyses and reporting of the REVAMP trial after unblinding the treatment allocations. Conclusions: A statistical analysis plan allows for transparency as well as reproducibility of reporting and statistical analyses.

Authors: Mirus Alicja , Zdziarski Krzysztof 
Published: April 2022

Abstract
Painful shoulder syndrome is a common condition of the musculoskeletal system in adults. This disorder affects your ability to work, overall body function, sleep, and quality of life. The treatment of shoulder syndrome is multifaceted and covers a broad spectrum of physiotherapy options. These include progressive strengthening exercises, laser therapy, electrotherapy and magnetotherapy. There are a number of treatments available that are reimbursed by the National Health Fund (NFZ). Aim of the research: The aim of the research was to assess the impact of rehabilitation on the treatment of shoulder pain syndrome.
Material and methods: The method used in the study was a diagnostic survey. The research was supplemented with an author's questionnaire to compare demographic data and assess the quality of life. The ranges of mobility were assessed before and after 10 series of treatments and the level of pain using the VAS scale. The study involved 80 patients presenting with the diagnosis of painful shoulder syndrome, 60% of whom were women and 40% men. The most numerous age group was between 50-60 years old (31 people) and 30-40 years old (24 people).
Results: The treatment process was successful in patients. Out of the studied population, 95% of patients experienced an improvement in their health compared to the baseline. A significant reduction in pain was observed with the use of physiotherapeutic procedures. The patients most favorably assessed massage, kinesiotherapy and cryotherapy. Conclusions: Conservative treatment reimbursed under the National Health Fund is an effective method of improving mobility and reducing to a large extent discomfort in the shoulder joint.
Coordinate Descent Without Coordinates: Tangent Subspace Descent on Riemannian Manifolds
Authors: Gutman David H. , Ho-Nguyen Nam 
Published: April 2022

We extend coordinate descent to manifold domains and provide convergence analyses for geodesically convex and nonconvex smooth objective functions. Our key insight is to draw an analogy between coordinate blocks in Euclidean space and tangent subspaces of a manifold. Hence, our method is called tangent subspace descent (TSD). The core principle behind ensuring convergence of TSD is the appropriate choice of subspace at each iteration. To this end, we propose two novel conditions, the (C, r)-norm and C-randomized norm conditions on deterministic and randomized modes of subspace selection, respectively, that promise convergence for smooth functions and that are satisfied in practical contexts. We propose two subspace selection rules, one deterministic and another randomized, of particular practical interest on the Stiefel manifold. Our proof-of-concept numerical experiments on the sparse principal component analysis problem demonstrate TSD’s efficacy.

Pros y contras del teletrabajo en la salud física y mental de la población general trabajadora: una revisión narrativa exploratoria
Authors: Tomasina Fernando , Pisani Adriana 
Published: April 2022

El teletrabajo es una realidad compleja que se encuentra en pleno desarrollo desde hace varias décadas. La situación de pandemia por la COVID-19 aceleró dicho proceso. Son variadas las formas de presentación, siendo la del trabajo a domicilio quizás de las más frecuentes. El objetivo del presente estudio fue realizar una revisión narrativa exploratoria y reflexiva sobre el teletrabajo en los aspectos positivos (pros) y negativos (contras) en relación con la salud física y mental de la persona teletrabajadora.
Así, de la literatura consultada se identifican factores de riesgo para la salud de los teletrabajadores, mayoritariamente corresponden a daños derivados de la exposición a riesgos psicosociales y ergonómicos. Destacan como daños a la salud mental las alteraciones del sueño, la ansiedad y la angustia y la depresión. Con respecto a los daños a la salud física se identifican trastornos músculo-esqueléticos, alteraciones derivadas de la disminución de la actividad física por el sedentarismo y el estrés, en particular enfermedades no transmisibles, y alteraciones de la visión.
Desde la prevención se deberán fomentar acciones dirigidas a políticas vinculadas con la organización del teletrabajo. En particular se deberá prestar atención a los tiempos de trabajo y de descanso, asegurando el denominado derecho a la desconexión. El diseño ergonómico del puesto de trabajo y la realización de pausas activas son elementos que contribuyen también al bienestar del trabajador. La participación activa de los actores sociales, trabajadores, empleadores y Estado, resulta estratégica para que el teletrabajo contribuya al trabajo decente y no a su precarización.
La regulación del teletrabajo estructural en Iberoamérica
Authors: Carrizosa-Prieto Esther 
Published: April 2022

La pandemia originada por la COVID-19 ha provocado, como necesidad súbita e imprevisible, la implantación del teletrabajo en los sistemas productivos de la generalidad de los países. Muchos Estados han tenido que recurrir a normas antiguas y desfasadas que no asumían las pocas garantías de los instrumentos internacionales y supranacionales existentes. Sin embargo, otros países han aprovechado la situación de emergencia sanitaria para reformar y actualizar sus normas de teletrabajo.
La presente contribución tiene por objeto analizar las nuevas normas surgidas con ocasión de la pandemia y efectuar una valoración general de sus contenidos para comprobar si se adaptan a las exigencias y recomendaciones que, en una sociedad digital, deben caracterizar al teletrabajo. Para ello hacemos un recorrido por el ordenamiento internacional con la finalidad de identificar los instrumentos, reglas y principios que nos puedan ayudar a perfilar las instituciones básicas que deben sostener la regulación del teletrabajo para, seguidamente, hacer una valoración de las legislaciones que en los últimos meses se han implantado en algunos de los países que integran el espacio iberoamericano (Argentina, Bolivia, Chile, Colombia, Costa Rica, España, El Salvador, México, Perú, Portugal) para hacer frente a esta realidad.
El análisis efectuado evidencia que, aún con escasos referentes internacionales, los distintos ordenamientos han sabido articular regulaciones garantistas que observan las pocas directrices existentes: voluntariedad, reversibilidad y un conjunto importante de derechos para las personas teletrabajadoras. No obstante, existen cuestiones pendientes que deben ser abordadas con una mayor profundidad: las relacionadas con el derecho a la salud laboral y con los derechos digitales, así como el desarrollo de la institución mediante la negociación colectiva, mecanismo que podría equilibrar los distintos intereses y garantizar una mayor aceptación de estas regulaciones.

Published: April 2022

Background/Aims The COVID-19 pandemic challenged not only global healthcare systems, but also educational systems, with many large, in-person training programmes being suspended. Instead, virtual learning platforms have been used, with promising results. This study explored the effectiveness of a virtual quality improvement training programme in a healthcare setting. Methods A 6-week interprofessional virtual quality improvement training programme was developed and delivered to a total of 137 participants across three cohorts. Pre- and post-programme surveys were administered to assess knowledge gained from training. Focus groups were also conducted for more in-depth feedback about the sessions. Information was then collected regarding any quality improvement projects participants had undertaken after completing the training. Results Mean scores were higher in the post-programme than the pre-programme survey across all knowledge domains (P<0.001, Cohens d=6.63). Over 80% of participants reported that the training improved their understanding of and confidence in undertaking a quality improvement project, and that they would recommend the training to their colleagues. Participants went on to either lead or contribute to a variety of quality improvement projects across a wide range of specialisms. Conclusions The virtual quality improvement training programme is an effective method of teaching, leading to participants being able to demonstrate competency in quality improvement. This approach to training delivery represents an efficient alternative to in-person training for building capability in frontline healthcare staff.

Published: April 2022

In this study, we proposed a novel refractive index sensor structure, comprising a metal–insulator–metal (MIM) waveguide and a circular ring containing a disk-shaped cavity (CRDC). The finite element method was used to theoretically analyze the sensor characteristics. The simulation results showed that the disk-shaped cavity is the key to the asymmetric Fano resonance, and the radius of the CRDC has a significant influence on the performance of the sensor. A maximum sensitivity and figure of merit (FOM) of 2240 nm/RIU and 62.5, respectively, were realized. Additionally, the refractive index sensor exhibits the potential of aiding in temperature detection owing to its simple structure and high sensitivity of 1.186 nm/ºC.

Published: April 2022

BackgroundType 2 diabetes is becoming highly prevalent worldwide and it is one of the leading causes of mortality. The cause of mortality among these patients is mostly related to the dominant presence of modifiable cardiovascular risk factors such as obesity. The aim of the current study is therefore to determine the prevalence of obesity and its associated factors among patients with type 2 diabetes mellitus at Sidama region, Ethiopia.MethodInstitution-based cross-sectional study design was implemented to determine the prevalence of obesity and its associated factor among patients with type two diabetes at Hawassa University Comprehensive Specialized Hospital and Yirgalem General Hospital from October 16 2018 to December 21, 2018. A simple random sampling technique was implemented to select 314 study participants. After obtaining consent, different patients’ related data were collected using a questionnaire. Patients’ records were also reviewed. 4ml of the blood sample was collected from each study participant and analyzed for lipid profile test. Blood glucose level was done using COBAS INTEGRA 6000. A binary logistic regression was used to assess factors that have an association with obesity. A P-value of <0.05 was considered statistically significant.ResultThe majority of the study participants (67.2%) were male and 61.8% of the study participants were aged >45years. The overall prevalence of overweight and obesity among the study participants was 36.3% and 18.8% respectively. About 41% of the study participants have a normal BMI. Females were more obese (28.2% Vs 14.2%) than males and BMI stratification by sex was statistically significant (P = 0.02). Sex (AOR = 3.0, CI = 1.6–5.7, P-Value = 0.001) and TG (AOR = 3.6, CI = 1.6–8.3, P-Value = 0.003) are factors that were independently associated with obesity among type 2 DM patients.ConclusionOverweight and obesity among type two diabetic patients were prevalent. In addition, obesity and overweight disorder are common among T2DM and gender and triglycerides levels were associated with obesity.

ObjectiveImproving the quality of life (QoL) of people living with HIV (PLWH) has been proposed as a new priority in HIV care. The objective of this cross-sectional, qualitative study was to explore the perspectives of PLWH in Greece regarding their QoL.DesignTwenty-four semi-structured interviews were conducted with PLWH receiving care across six HIV clinics in Greece. The thematic analysis of the transcribed interviews resulted in four themes and eleven subthemes.ResultsFirst, fear of repercussions (e.g., stigmatization) makes PLWH reluctant to disclose their diagnosis in public settings or disclose accounting for factors like the confidant’s discretion. Second, participants are challenged by HIV’s unique biopsychosocial facets (e.g., uncertainty about symptoms) and fear for the future (e.g., a confidant revealing their HIV status without consent). Third, support received by specialist services is satisfactory in contrast to non-HIV specialist services, where significant improvements are needed to reduce stigmatization. Finally, the experiences of PLWH include contrasting elements of post-traumatic growth and an inability to accept their seropositivity (e.g., avoiding social interactions).ConclusionsEmpowering PLWH in these QoL areas is greatly needed. Increasing the life expectancy of PLWH is only the initial step; their QoL needs to be secured as the next priority in HIV care.

Published: April 2022

BackgroundThe COVID-19 pandemic is likely to influence psychological health of pregnant and postpartum women.MethodsWe conducted a non-concurrent cross-sectional study among 1145 women living in the Dutch-speaking part of Belgium, 541 pregnant and 604 postpartum women. We measured psychological health with the Whooley questions, Generalized Anxiety Disorder 2-item (GAD-2) and the Edinburgh Postnatal Depression Scale (EPDS) and compared the scores of pregnant and postpartum women before and during the COVID-19 pandemic.ResultsNo differences were observed in the Whooley, GAD-2 or EPDS scores among pregnant women. The postpartum total GAD-2 scores beforevsduring the pandemic showed significant differences. Controlling for confounders, we observed a small main positive effect of having an infant during time of COVID-19 (F(1.13) = 5.06,p.025,d.27). The effect was significantly larger for women with (a history of) perinatal psychological problems (F(1.12) = 51.44,p< .001,d.82). Emotional support was significantly related to GAD-2 scores of postpartum women during the pandemic (F(1.90) = 35.54,p< .001). Postpartum women reported significant higher effects of the pandemic on their behavior compared to pregnant women (p.034).ConclusionThe COVID-19 pandemic seems to have a positive effect on postpartum women during the first year postpartum, in particular for women with (a history of) perinatal psychological problems and for those women who experienced emotional support. The findings suggest that less external stimuli caused by lockdown restrictions might have a positive effect on postpartum women’s emotional wellbeing. The sample consisted of white, educated women in a relationship and information regarding the extent of exposure to adverse COVID-19 consequences was lacking. We relied on self-selection and self-report. The postpartum pandemic sample was small.
Differential COVID-19 testing, admissions, and mortality for Arab Americans in Southern California
Authors: Abuelezam Nadia N. , Greenwood Kristina L. , Galea Sandro , Al-Naser Raed 
Published: April 2022

Background
Understanding of COVID-19 acquisition and severity risk in minoritized groups is limited by data collection on race and ethnicity; very little is known about COVID-19 risk among Arab Americans in the United States.

Purpose
To quantify whether Arab Americans in the El Cajon region of California experienced differential levels of SARS-CoV-2 infection, severity and mortality when compared to other racial/ethnic groups.

Methods
A retrospective study was conducted using Sharp Grossmont Hospital’s electronic medical records. Patients were included in the study if they were: 18 years of age or older, tested for SARS-CoV-2, admitted for COVID-19 infection, or had COVID-19 listed as a cause of death between March 1, 2020 and January 31, 2021. The primary outcomes of interest were a positive COVID-19 test result, admission to the hospital due to COVID-19, and in hospital COVID-19 related mortality. Comparisons were made across racial/ethnic groups using chi-squared statistics and logistic regression models adjusted for sociodemographics, comorbidities, and time from March 2020.

Results
Arab Americans had greater odds of testing positive for SARS-CoV-2 than non-Hispanic White (adjusted odds ratio, AOR: 3.83, 95% confidence interval, CI: 3.29, 4.46) and non-Hispanic Black (AOR: 2.34, 95% CI: 1.91, 2.88) patients but lower odds of admission (AOR: 0.47, 95% CI: 0.36, 0.63) and in-hospital mortality (AOR: 0.43, 95% CI: 0.28, 0.65) than Hispanic patients.

Conclusions
There were distinct patterns for COVID-19 infection, severity, and mortality for Arab Americans in Southern California. Without a dedicated ethnic identifier, COVID-19 disparities facing Arab Americans will continue to go undocumented.
On the Cerbo Conjecture on Lie Groups with the Left-Invariant Lorentzian Metric
Authors: Balashchenko V.V. , Klepikov P.N. , Rodionov E.D. , Khromova O.P. 
Published: April 2022

Manifolds with constraints on tensor fields include Einstein manifolds, Einstein-like manifolds, conformally flat manifolds, and a number of other important classes of manifolds. The work of many mathematicians is devoted to the study of such manifolds, which is reflected in the monographs of A. Besse, M. Berger, M.-D. Cao, M. Wang.
Ricci solitons are one of the natural generalizations of Einstein's metrics. If a Riemannian manifold is a Lie group, one speaks of invariant Ricci solitons.
Invariant Ricci solitons were studied in most detail in the case of unimodular Lie groups with left-invariant Riemannian metrics and the case of low dimension. Thus, L. Cerbo proved that all invariant Ricci solitons are trivial on unimodular Lie groups with left-invariant Riemannian metric and Levi-Civita connection.A similar result up to dimension four was obtained by P.N. Klepikov and D.N. Oskorbin for the non-unimodular case.
We study invariant Ricci solitons on three-dimensional unimodular Lie groups with the Lorentzian metric.The study results show that unimodular Lie groups with left-invariant Lorentzian metric admit invariant Ricci solitons other than trivial ones. In this paper, a complete classification of invariant Ricci solitons on three-dimensional unimodular Lie groups with leftinvariant Lorentzian metric is obtained.
