Authors: Yoshida Yilin , Wang Jia , Zu Yuanhao 
Published: August 2022

BackgroundThe differential effect of comorbidities on COVID-19 severe outcomes by sex has not been fully evaluated.ObjectiveTo examine the association of major comorbidities and COVID-19 mortality in men and women separately.MethodsWe performed a retrospective cohort analysis using a large electronic health record (EHR) database in the U.S. We included adult patients with a clinical diagnosis of COVID-19 who also had necessary information on demographics and comorbidities from January 1, 2016 to October 31, 2021. We defined comorbidities by the Charlson Comorbidity Index (CCI) using ICD-10 codes at or before the COVID-19 diagnosis. We conducted logistic regressions to compare the risk of death associated with comorbidities stratifying by sex.ResultsA total of 121,342 patients were included in the final analysis. We found significant sex differences in the association between comorbidities and COVID-19 death. Specifically, moderate/severe liver disease, dementia, metastatic solid tumor, and heart failure and the increased number of comorbidities appeared to confer a greater magnitude of mortality risk in women compared to men.ConclusionsOur study suggests sex differences in the effect of comorbidities on COVID-19 mortality and highlights the importance of implementing sex-specific preventive or treatment approaches in patients with COVID-19.

PurposeTo evaluate the volumetric change of COVID-19 lesions in the lung of patients receiving serial CT imaging for monitoring the evolution of the disease and the response to treatment.Materials and methodsA total of 48 patients, 28 males and 20 females, who were confirmed to have COVID-19 infection and received chest CT examination, were identified. The age range was 21–93 years old, with a mean of 54 ± 18 years. Of them, 33 patients received the first follow-up (F/U) scan, 29 patients received the second F/U scan, and 11 patients received the third F/U scan. The lesion region of interest (ROI) was manually outlined. A two-step registration method, first using the Affine alignment, followed by the non-rigid Demons algorithm, was developed to match the lung areas on the baseline and F/U images. The baseline lesion ROI was mapped to the F/U images using the obtained geometric transformation matrix, and the radiologist outlined the lesion ROI on F/U CT again.ResultsThe median (interquartile range) lesion volume (cm3) was 30.9 (83.1) at baseline CT exam, 18.3 (43.9) at first F/U, 7.6 (18.9) at second F/U, and 0.6 (19.1) at third F/U, which showed a significant trend of decrease with time. The two-step registration could significantly decrease the mean squared error (MSE) between baseline and F/U images with p &lt; 0.001. The method could match the lung areas and the large vessels inside the lung. When using the mapped baseline ROIs as references, the second-look ROI drawing showed a significantly increased volume, p &lt; 0.05, presumably due to the consideration of all the infected areas at baseline.ConclusionThe results suggest that the registration method can be applied to assist in the evaluation of longitudinal changes of COVID-19 lesions on chest CT.

AimsTo investigate the prevalence and the correlates of fear of COVID-19 among homeless individuals.MethodsWe used data from the “national survey on psychiatric and somatic health of homeless individuals during the COVID-19 pandemic” (NAPSHI-study) which took place in several large cities in Germany in Mid-2021 (n = 666 in the analytical sample). Mean age equaled 43.3 years (SD: 12.1 years), ranging from 18 to 80 years. Multiple linear regressions were performed.ResultsIn our study, 70.9% of the homeless individuals reported no fear of COVID-19. Furthermore, 14.0% reported a little fear of COVID-19, 8.4% reported some fear of COVID-19 and 6.7% reported severe fear of COVID-19. Multiple linear regressions revealed that fear of COVID-19 was higher among individuals aged 50–64 years (compared to individuals aged 18–29 years: β = 0.28, p &lt; 0.05), among individuals with a higher perceived own risk of contracting the coronavirus 1 day (β = 0.28, p &lt; 0.001) as well as among individuals with a higher agreement that a diagnosis of the coronavirus would ruin his/her life (β = 0.15, p &lt; 0.001).ConclusionsOnly a small proportion of homeless individuals reported fear of COVID-19 in mid-2021 in Germany. Such knowledge about the correlates of higher levels of fear of COVID-19 may be helpful for addressing certain risk groups (e.g., homeless individuals aged 50–64 years). In a further step, avoiding extraordinarily high levels of fear of COVID-19 may be beneficial to avoid irrational thinking and acting regarding COVID-19 in this group.

BackgroundPrevious studies have shown that cancer patients have higher rates of coronavirus disease 2019 (COVID-19) infection and mortality than noncancer patients. However, the differences between cancer patients undergoing regular follow-up without anticancer treatment and noncancer patients with COVID-19 have remained insufficiently investigated.MethodsA retrospective case–control study of 52 patients with COVID-19 infection was performed with a 1:3 matched proportion of cancer patients undergoing regular follow-up without anticancer treatment and noncancer patients. The demographic characteristics, clinical data, laboratory tests, treatment, and complications of patients were collected from medical records. Chi-square tests and univariate and multivariate regressions were performed to assess the differences between these two cohorts of COVID-19 patients with and without cancer and risk factors for severe events in COVID-19 patients.ResultsIncreased C-reactive protein (CRP) (&gt;4 mg/L) (p = 0.015) and lactate dehydrogenase (LDH) (&gt;243 IU/L) (p = 0.038) were identified as risk factors for severe events in all enrolled COVID-19 patients based on multivariate analysis, but cancer as a chronic disease (p = 1.000) was not identified as an independent risk factor for severe events in COVID-19 patients. Compared with noncancer patients, cancer patients had a significantly longer median hospitalization time (29 days vs. 19 days, p = 0.048) and a higher incidence of hypoalbuminemia complications (84.6 vs. 46.2%, p = 0.016).ConclusionsIncreased CRP and LDH were risk factors for severe events in all enrolled COVID-19 patients, and an increased incidence of hypoalbuminemia complications and longer hospitalization were noted in COVID-19 cancer patients undergoing regular follow-up without anticancer treatment compared with noncancer patients.

BackgroundCurrently, longitudinal studies on frailty are in an early stage, particularly in low- and middle-income countries. Only one study was conducted in Hong Kong to examine age-period-cohort effects on the prevalence of frailty among Chinese older adults.ObjectivesThis study aims to shed light on the prevalence trajectory of frailty among older adults in mainland China through the APC model and to analyze the effects of age, period, and cohort on the prevalence trajectory.MethodsThe sample for this study was older adults aged 65–109 years old from the 2002 to 2014 Chinese Longitudinal Healthy Longevity Survey (CLHLS). Frailty status was measured by Rockwood FI. An age-period-cohort model was used to describe the effects of age, period, and cohort on the prevalence trajectory of frailty.ResultsThe prevalence of frailty among Chinese older adults changed significantly with age, period, and cohort. Furthermore, the effect of age was much stronger than the effect of period and cohort. The prevalence of frailty in the 101–103 and 104–106 age groups was 8.998 (95% CI 13.667–5.924) and 8.699 (95% CI 13.037–5.805) times higher than the in the 65–67 age group, respectively. The sensitivity analysis based on Fried's frailty phenotype showed similar results, confirming the robustness of our findings.ConclusionAll of the age effect reflecting the individual aging process, period effect reflecting change in the social environment, and birth cohort effect reflecting different generations could influence the prevalence of frailty at the population level. In contrast, the age effect was the main effect.
Efecto de tres técnicas de polinización sobre el rendimiento de Palma Aceitera (Elaeis guineensis Jacq.) de 4 años
Authors: Huaringa Daniel 
Published: August 2022

La palma aceitera es un cultivo con un creciente aumento en su producción, la deficiente producción de frutos durante los primeros años de este cultivo se debe a la poca presencia de inflorescencias masculinas y por ende una baja población de insectos polinizadores. El objetivo de este estudio fue comparar técnicas de polinización que permitan incrementar el rendimiento de la palma aceitera durante sus primeros 4 años de producción. Se evaluaron tres técnicas de polinización para mejorar rendimientos productivos: polinización natural, polinización entomófila dirigida y polinización asistida. Se asignó 5 repeticiones por tratamiento y el diseño usado fue un DCA, para el análisis de los datos se usó el software estadístico Minitab17. Las variables consideradas fueron: peso de racimo, número de frutos normales, número de frutos partenocárpicos rojos y blancos, y número de frutos abortados. El análisis estadístico indico diferencias significativas (p<0,05) para las variables peso de racimo, número de frutos normales y número de frutos partenocárpicos blancos; mientras que para las variables número de frutos partenocárpicos rojos y número de frutos abortados no se hallaron diferencias significativas (p>0,05). En el análisis comparativo de promedios el tratamiento con polinización entomófila dirigida mostro ser superior al resto. Los resultados indican que la polinización entomófila dirigida puede ser la solución para mejorar el bajo rendimiento de la palma aceitera durante sus primeros años de producción. En conclusión, en el presente ensayo la polinización entomófila dirigida mejoro los parámetros productivos en una plantación joven de palma aceitera.

Published: August 2022

Key Points

A pilot randomized controlled trial of integrated palliative and nephrology care in patients with CKD stage 5 not on dialysis is feasible.A pilot randomized controlled trial of integrated palliative and nephrology care in patients with nondialysis CKD 5 is acceptable.Participants in the integrated care arm had lower symptom burden scores at the end of the trial, whereas the control group had higher scores.

Background
There has been a call by both patients and health professionals for the integration of palliative care with nephrology care, yet there is little evidence describing the effect of this approach. The objective of this paper is to report the feasibility and acceptability of a pilot randomized controlled trial testing the efficacy of integrated palliative and nephrology care.

Methods
English speaking patients with CKD stage 5 were randomized to monthly palliative care visits for 3 months in addition to their usual care, as compared with usual nephrology care. Feasibility of recruitment, retention, completion of intervention processes, and feedback on participation was measured. Other outcomes included differences in symptom burden change, measured by the Integrated Palliative Outcome Scale–Renal, and change in quality of life, measured by the Kidney Disease Quality of Life questionnaire and completion of advance care planning documents.

Results
Of the 67 patients approached, 45 (67%) provided informed consent. Of these, 27 patients completed the study (60%), and 14 (74%) of those in the intervention group completed all visits. We found small improvements in overall symptom burden (−2.92 versus 1.57) and physical symptom burden scores (−1.92 versus 1.79) in the intervention group. We did not see improvements in the quality-of-life scores, with the exception of the physical component score. The intervention group completed more advance care planning documents than controls (five health care proxy forms completed versus one, nine Medical Orders for Life Sustaining Treatment forms versus none).

Conclusions
We found that pilot testing through a randomized controlled trial of an ambulatory integrated palliative and nephrology care clinical program was feasible and acceptable to participants. This intervention has the potential to improve the disease experience for those with nondialysis CKD and should be tested in other CKD populations with longer follow-up.

Dissociation channels of c-C4F8 to C2F4 in reactive plasma
Authors: Hayashi Toshio , Ishikawa Kenji , Iwayama Hiroshi , Sekine Makoto , Hori Masaru 
Published: August 2022

Abstract
Progress in computational methods and personal computing has made possible more accurate estimations for primary dissociation channels and energies. The main dissociation route is revealed to be via the 7E excited state with an energy of 12.23 eV, which is composed of transitions from the highest occupied molecular orbital with b1 symmetry to some degenerate unoccupied e molecular orbitals. The main contributing e orbitals consisted of antibonding combination of C2F4
π-bonding orbitals. This degenerate 7E state is lowered by non-adiabatic transitions through the conical interactions on the dissociating route to 2C2F4, so the energy is finally relaxed at the dissociative second lowest 1E excited state leading to 2C2F4 production. In the electron attachment process, the calculated results show that the F− ion is produced from the excited states of the D4h c-C4F8
− ion through conical interactions at the energies of 4.3 eV, 5.6 eV, and 5.0 eV, along the C–F dissociation route.
Socialización bilingüe infantil en Galicia
Authors: Díaz Ferro Marta 
Published: August 2022

El presente artículo muestra el trabajo de campo realizado en una escuela de una zona castellano-hablante en relación con las intervenciones conversacionales de niños de Educación Infantil escolarizados en gallego. Este alumnado, de familias castellano-hablantes en su mayoría, realiza contribuciones verbales dentro de una de las actividades alfabetizadoras denominada ‘‘proposición de palabras’’ que tiene lugar dentro de la rutina escolar más importante, el Tempo de Asemblea. Gracias a esta actividad, estos niños y niñas aprenden a planificar sus intervenciones recibiendo instrucciones en la que, para ellos, sería ya una segunda lengua: el gallego.
La metodología empleada para este trabajo consistió en una observación semi-participante acompañada de notas etnográficas tomadas en el momento de las visitas, así como de grabaciones de voz de las interacciones presenciadas en el aula, grabaciones que posteriormente serían transcritas y analizadas. Los resultados obtenidos a partir del análisis de estos datos muestran que el alumnado escogido no presenta confusión al entender y realizar las tareas pedidas por la maestra, quien utiliza como código base el gallego. Con este trabajo se muestra cómo la escolarización en esta lengua no es perjudicial para los discentes.
