Published: February 2022

Background
Stay-at-home orders and other public health measures designed to mitigate the spread of COVID-19 have increased isolation among persons with memory concerns (PWMCs: individuals diagnosed with cognitive impairment or Alzheimer disease or related dementias). The pandemic has also exacerbated challenges for family members who care for PWMCs. Although technology has demonstrated the potential to improve the social connections and mental health of PWMCs and their family caregivers (CGs), previous research shows that older adults may be reluctant to adopt new technologies.

Objective
We aimed to understand why and how some PWMCs and their CGs altered their use of mainstream technology, such as smartphones and fitness trackers, and assistive technology to adapt to lifestyle changes (eg, increased isolation) during the COVID-19 pandemic.

Methods
Using data collected in 20 qualitative interviews from June to August 2020 with 20 PWMCs and family CG dyads, we assessed changes in and barriers to everyday technology use following the implementation of COVID-19 mitigation strategies in the United States. Zoom videoconferencing was utilized to conduct the interviews to protect the health of the participants who were primarily older adults.

Results
Using qualitative thematic analysis, we identified 3 themes that explained motivations for using technology during a pandemic: (1) maintaining social connections, (2) alleviating boredom, and (3) increasing CG respite. Results further revealed lingering barriers to PWMC and CG adoption of technologies, including: (1) PWMC dependence upon CGs, (2) low technological literacy, and (3) limitations of existing technology.

Conclusions
This in-depth investigation suggests that technology can provide PWMCs with more independence and offer CGs relief from CG burden during periods of prolonged isolation.
Understanding Mental Health Professionals’ Perspectives and Practices Regarding the Implementation of Digital Mental Health: Qualitative Study
Authors: Mendes-Santos Cristina , Nunes Francisco , Weiderpass Elisabete , Santana Rui , Andersson Gerhard 
Published: February 2022

Background
Despite the potential of digital mental health to provide cost-effective mental health care, its adoption in clinical settings is limited, and little is known about the perspectives and practices of mental health professionals regarding its implementation or the factors influencing these perspectives and practices.

Objective
This study aims to characterize in depth the perspectives and practices of mental health professionals regarding the implementation of digital mental health and explore the factors affecting such perspectives and practices.

Methods
A qualitative study using in-depth semistructured interviews with Portuguese mental health professionals (N=13)—psychologists and psychiatrists—was conducted. The transcribed interviews were thematically analyzed.

Results
Mental health professionals deemed important or engaged in the following practices during the implementation of digital mental health: indication evaluation, therapeutic contract negotiation, digital psychological assessment, technology setup and management, and intervention delivery and follow-up. Low-threshold accessibility and professionals’ perceived duty to provide support to their clients facilitated the implementation of digital mental health. Conversely, the lack of structured intervention frameworks; the unavailability of usable, validated, and affordable technology; and the absence of structured training programs inhibited digital mental health implementation by mental health professionals.

Conclusions
The publication of practice frameworks, development of evidence-based technology, and delivery of structured training seem key to expediting implementation and encouraging the sustained adoption of digital mental health by mental health professionals.
The Influence of SARS-CoV-2 Variants on National Case-Fatality Rates: Correlation and Validation Study
Authors: Barletta William A 
Published: February 2022

BackgroundIn 2021, new variants of the SARS-CoV-2 virus appeared with increased transmissibility and virulence as compared with the original wild variant. The first variants of concern (VoCs), Alpha (B1.1.7) and Gamma (P.1), first appeared in the United Kingdom and Brazil, respectively. The Delta (B.1.617.2) variant, seen in India in October 2020, dominated COVID-19 infections across all regions through the second half of 2021.ObjectiveThis research explores the degree to which SARS-CoV-2 VoCs generate waves of fluctuations in case-fatality rates (CFRs) across countries in several regions, increase the risk of mortality to persons with certain comorbidities, and decrease the risk of mortality as the percentage of fully vaccinated populations increases.MethodsThis analysis introduces a measure of the temporal dynamics of COVID-19 infections in the form of a proxy CFR (pCFR), which can be compared among countries. It uses economic and demographic data reported by the World Bank and International Monetary Fund, plus publicly available epidemiological and medical statistics reported to the relevant national and international public health authorities. From these ecological data, pandemic average and daily COVID-19 CFRs and their correlations with potential cofactors were computed for 2021, a year dominated by the spread of World Health Organization–designated VoCs. The study does not investigate disease pathology; rather, it compares the daily case rates and pCFRs to reveal underlying contributing factors that vary from country to country and region to region.ResultsThe in-depth global regression analysis of cofactors found that the strongest single correlation with COVID-19 fatality was 0.36 (SD 0.02) with P<.001 for chronic kidney disease. No other single physiological cofactors display positive correlations exceeding 0.26 (SD 0.26), with P=.008 (asthma) and P=.01 (coronary disease). The study confirms that the pCFR is a valuable metric for tracking waves of infection due to different VoCs within countries.ConclusionsThe influence of social, economic, and medical cofactors on the CFR due to VoCs remains qualitatively similar, albeit strengthened, to the levels found for the wild strain. The strong regional variations of the influence of all cofactors observed for the wild strain persists in infections for all VoCs with very strong correlation coefficients seen in the Middle East for asthma (0.76), coronary heart disease (0.60), lung disease (0.70), and chronic kidney disease (0.52). Strong regional variations emphasize the influence on COVID-19 mortality due to regional differences in national economics, patterns of health care policies, and variations in cultural practices and environment. The pCFR-based analysis reveals clear patterns of the spread of VoCs across regions, but there is little evidence for the spread of the Lambda and Mu (B.1.621) variants of interest outside of South America.

El objetivo de este texto es exponer cómo la higiene se convirtió en un elemento fundamental del diseño y de la organización social en la etapa posrevolucionaria en la Ciudad de México. Para demostrarlo, trazaremos tres líneas convergentes. La primera concerniente a la propuesta filosófica, educativa y de diseño nacionalista mexicano llevada a cabo por José Vasconcelos con la política pública versada en la higiene; la segunda en relación a cómo los innovadores descubrimientos científicos, tecnológicos e industriales produjeron nuevas aportaciones en el campo del diseño y en la medicina; y la tercera en torno a la forma en que esta iniciativa se reflejó en la cotidianidad de los habitantes de la Ciudad de México a través de los objetos de higiene personal, de limpieza doméstica y en el diseño art déco de interiores de la casa habitación de la clase media.Este texto presenta una investigación cualitativa que inicia por el método descriptivo, analítico y por momentos históricos. Además, se basa en elementos hemerográficos y documentales del periódico El Universal de 1935, Revista de Revistas de 1927, Paquita de 1939, El Quijote de 1925 y El Niño 1921.
Family Archives in the 16th Century. The Mikola Family Archive
Authors: LUPESCU MAKÓ Mária 
Published: February 2022

In April 1573, after the death of the head of the family, Ferenc Mikola, the elders of the Mikolas gathered in Someşeni to take over the family archive from his widow. The action carried out according to the custom, but also to the legislation of the country took place in the presence of witnesses, later a proving act being issued. The present study aims to investigate the process of handing over the noble family archives in Transylvania from the end of the Middle Ages and during the sixteenth century. In this context, the ways of keeping and ordering the charters during the researched period, as well as the circumstances of the formation of the noble family archives will be examined. The focus will be on the presentation of a case study, that of the Mikola family archive. Starting from the charter issued in April 1573, we shall briefly present the Mikola family, their family archive, but also the witnesses of the archive’s transmission. Among the latter, we shall pay a special attention to Ferenc Dávid, the parish priest of Cluj and superintendent. The second title carried by the religious reformer shall provide the opportunity to reflect on the formation of the Reformed and Unitarian Churches in Transylvania.

În aprilie 1573, după moartea capului familiei, Ferenc Mikola vârstnicii familiei Mikola s-au adunat la Someşeni pentru a prelua de la văduva acestuia arhiva familiei. Acţiunea desfăşurată potrivit cutumei, dar şi legislaţiei ţării a avut loc în prezenţa martorilor, ulterior eliberându-se şi un act doveditor. Studiul de faţă îşi propune să cerceteze procedeul predării arhivelor familiare nobiliare din Transilvania de la sfârşitul Evului mediu şi pe parcursul secolului al XVI-lea. În acest context vor fi prezentate modalităţile de păstrare şi ordonare a documentelor în perioada cercetată, precum şi împrejurările formării arhivelor familiare nobiliare. Accentul va fi pus pe prezentarea unui studiu caz, cel al arhivei familiei Mikola. Pornind de la documentul din aprilie 1573, vom prezenta pe scurt familia Mikola, arhiva familiei, dar şi martorii acţiunii de predare a arhivei. Dintre aceştia din urmă îi vom acorda o atenţie deosebită lui Ferenc Dávid, preotul paroh al oraşului Cluj şi superintendent. Titlul din urmă purtat de reformatorul religios va oferi ocazia să reflectăm şi asupra formării Bisericilor Reformate şi Unitariene din Transilvania.
