<li><strong>The global polarisation of remote work</strong> -
|
|||
|
|
<div>
|

|

The Covid-19 pandemic has led to the rise of digitally enabled remote work with consequences for the global division of labour. Remote work could connect labour markets, but it might also increase spatial polarisation. However, our understanding of the geographies of remote work is limited. Specifically, in how far could remote work connect employers and workers in different countries? Does it bring jobs to rural areas because of lower living costs, or does it concentrate in large cities? And how do skill requirements affect competition for employment and wages? We use data from a fully remote labour market - an online labour platform - to show that remote platform work is polarised along three dimensions. First, countries are globally divided: North American, European, and South Asian remote platform workers attract most jobs, while many Global South countries participate only marginally. Secondly, remote jobs are pulled to large cities; rural areas fall behind. Thirdly, remote work is polarised along the skill axis: workers with in-demand skills attract profitable jobs, while others face intense competition and obtain low wages. The findings suggest that agglomerative forces linked to the unequal spatial distribution of skills, human capital, and opportunities shape the global geography of remote work. These forces pull remote work to places with institutions that foster specialisation and complex economic activities, i.e. metropolitan areas focused on information and communication technologies. Locations without access to these enabling institutions - in many cases, rural areas - fall behind. To make remote work an effective tool for economic and rural development, it would need to be complemented by local skill-building, infrastructure investment, and labour market programmes.

<li><strong>Disassociating conformity driven and self-interest driven dishonest behaviors</strong> -
|

|

<div>
|

|

Learning from others’ dishonesty usually encompasses various motivations, for example, the destination to pursue self-interest and the tendency to conform to the group norm. However, these different processes were rarely dissociated previously, which impedes the understanding of how the individual dishonest behavior propagates and becomes popular in the community. We built a comprehensive model based on the reinforcement learning framework to depict both the processes of rational self-interest propensity and dishonesty conformity and examined their roles during the social learning of dishonesty. With an agent-based simulation and empirical studies in samples of diverse cultural backgrounds, we found rational self-interest propensity was the primary factor that drives dishonest acts of self-interest, whereas the effect of dishonesty conformity was conditional and context-dependent. With an fMRI experiment, we found the brain implemented dishonesty conformity differently when it serves distinct goals. Besides, these two processes of dishonesty were encoded by non-overlapping dynamic interactions between the brain regions. In the background of the COVID-19 pandemic where public coordination is highly demanded but at a cost of self-interest, we found that these two processes of dishonesty exerted discrepant effects on residents’ attitudes towards the local epidemic control and impacted the prevalence of pathogens unevenly.

<li><strong>Related factors of depressive symptoms vary among adolescents and young adults during the COVID-19 pandemic</strong> -

Depression represents a public health problem, especially in the adolescent and young adult populations. Studies have shown that during the COVID-19 outbreak, depressive symptoms were associated with economic instability, among other aspects related to isolation. The present study seeks to identify sociodemographic characteristics and situations associated with the presence of depressive symptoms in young people (N = 2058) in an Andean city at the beginning of the COVID-19 outbreak. Logistic regression analysis reveals that the factors predicting depressive symptoms vary between adolescents and young adults. The results show that perceived health status, satisfaction with virtuality, and being a woman are related to depressive symptoms. Likewise, it was found that, in young adults, but not in adolescents, the level of economic income and taking virtual classes were related to symptomatology. Receiving economic income turned out to have a differentiated effect according to age group since this factor increases the probability of developing depressive symptomatology in adolescents, while it reduces this probability in the older age group. Finally, the findings of this study are discussed by evidence from other studies in different countries.

Objective: This study compared mental health outcomes among people enrolled in an evidence-based digital mental health intervention before and during the onset of the COVID-19 pandemic. Methods: Growth curve modeling was used to evaluate changes in biweekly depression and anxiety scores from 131 adults who participated pre- (2019; n=51) versus during- (2020; n=80) pandemic onset. Results: Individuals who completed the intervention during the pandemic (2020) had less steep declines in depression symptoms than those who participated pre-pandemic (2019). Despite an initial relative increase in anxiety and depression scores at the onset of the pandemic, differences in overall change in outcomes between the two cohorts were not evident by program completion. Conclusions: Participation in an evidence-based, digital mental health intervention during the onset of the COVID-19 pandemic was associated with similar magnitudes of symptom improvement as participation before the pandemic.

Background Hospital-at-home (HaH) care has been proposed as an alternative to inpatient care for patients with COVID-19. Previous reports were hospital-led and involved patients triaged at the hospitals. To reduce the burden on hospitals, we constructed a novel HaH care model organised by a team of local primary care clinics. Methods We conducted a multi-center retrospective cohort study of the COVID-19 patients who received our HaH care from Jan 1st to Mar 31st, 2022. Patients who were not able to be triaged for the need for hospitalization by the Health Center solely responsible for the management of COVID-19 patients in Osaka City were included. The primary outcome was receiving medical care beyond the HaH care defined as a composite outcome of any medical consultation, hospitalization, or death within 30 days from the initial treatment. Results Of 382 eligible patients, 34 (9%) were triaged for hospitalization immediately after the initial visit. Of the remaining 348 patients followed up, 37 (11%) developed the primary outcome, while none died. Obesity, fever, and gastrointestinal symptoms at baseline were independently associated with an increased risk of needing medical care beyond the HaH care. A further 129 (37%) patients were managed online alone without home visit, and 170 (50%) required only one home visit in addition to online treatment. Conclusions The HaH care model with a team of primary care clinics was able to triage patients with COVID-19 who needed immediate hospitalization without involving hospitals, and treated most of the remaining patients at home.

Background The COVID-19 pandemic has had a significant impact on delivery of NHS care. We have developed the OpenSAFELY Service Restoration Observatory (SRO) to describe this impact on primary care activity and monitor its recovery. Objectives To develop key measures of primary care activity and describe the trends in these measures throughout the COVID-19 pandemic. Methods With the approval of NHS England we developed an open source software framework for data management and analysis to describe trends and variation in clinical activity across primary care electronic health record (EHR) data on 48 million adults. We developed SNOMED-CT codelists for key measures of primary care clinical activity selected by a expert clinical advisory group and conducted a population cohort-based study to describe trends and variation in these measures January 2019-December 2021, and pragmatically classified their level of recovery one year into the pandemic using the percentage change in the median practice level rate. Results We produced 11 measures reflective of clinical activity in general practice. A substantial drop in activity was observed in all measures at the outset of the COVID-19 pandemic. By April 2021, the median rate had recovered to within 15% of the median rate in April 2019 in six measures. The remaining measures showed a sustained drop, ranging from a 18.5% reduction in medication reviews to a 42.0% reduction in blood pressure monitoring. Three measures continued to show a sustained drop by December 2021. Conclusions The COVID-19 pandemic was associated with a substantial change in primary care activity across the measures we developed, with recovery in most measures. We delivered an open source software framework to describe trends and variation in clinical activity across an unprecedented scale of primary care data. We will continue to expand the set of key measures to be routinely monitored using our publicly available NHS OpenSAFELY SRO dashboards with near real-time data.

Objectives. Hearing loss is the leading potentially modifiable risk factor for dementia. A potential mediator in the relationship between hearing loss and increased dementia risk is the psychosocial pathway, which suggests that increased social isolation and mental health factors associated with hearing loss causes increased dementia risk and exacerbates dementia symptoms. In March 2020, the UK government announced social restriction measures to reduce the spread of the virus that causes COVID-19, with older adults who were considered clinically vulnerable needing to isolate. This study aimed to determine the impact of psychosocial factors, including loneliness, depression, and engagement in various recreational lifestyle activities, on hearing and cognitive function in younger and older adults during the COVID-19 pandemic. It was hypothesised that auditory and cognitive function would be significantly predicted by age, psychosocial factors, and time since the start of the first UK COVID-19 lockdown. Additionally, auditory function was hypothesised to be associated with cognitive functioning. Design. Participants included 112 older adults (62 female) aged 60-83 (M = 70.75, SD = 5.88), and 121 younger adults (85 female) aged 18-30 (M = 21.04, SD = 2.75). Participants took part online from June 2020 - February 2021 and completed a series of questionnaires assessing loneliness, depression, auditory and lifestyle engagement, and subjective hearing ability. They also completed a series of behavioural tasks assessing speech perception, short-term and working memory, processing speed, and executive function, providing composite measures of global cognitive functioning and auditory functioning. Results. Multiple regression analyses found that, of the variables examined, age significantly predicted both global cognitive and auditory function, with older adults displaying poorer auditory and cognitive performance. While age was the only significant predictor in the model predicting cognitive performance, in the model predicting auditory function increased depressive symptoms were a significant predicter alongside age. Further, auditory function did not significantly predict cognitive function. Conclusions. These data suggest that that loneliness and socialisation do not contribute to reductions in cognitive or auditory functioning, nor did time since the start of the first UK lockdown. Thus, suggesting that hearing and cognition may not have been adversely affected by social restrictions during the COVID-19 pandemic. This provides important implications for understanding whether the relationship between hearing loss and cognitive decline is mediated by the psychosocial pathway. However, the study represents only cross-sectional data collected from a potentially biased sample of higher socio-economic position. Future work should seek to address if these conclusions are also valid in populations with different socio-economic characteristics.

Despite recognition of the diversity of the Asian American population, the mortality impact of the COVID-19 pandemic has been limited to estimates for non-Hispanic Asian Americans in aggregate. This study provides estimates of life expectancy at birth before (2019) and during the pandemic, along with a broad set of demographic, health-related, and socioeconomic risk factors for COVID-19, for the six largest Asian American subgroups: Asian Indians, Chinese, Filipino, Japanese, Korean, and Vietnamese. Our study places these estimates in the context of the broader U.S. population by including the corresponding estimates for non-Hispanic Whites, non-Hispanic Blacks, Hispanics, and non-Hispanic Native Americans. We use data on age-specific all-cause mortality from CDC WONDER and population estimates from the 2015-2019 American Community Survey to construct life tables for each Asian subgroup by year. While losses in life expectancy during the second year of the pandemic diminished significantly among all racial/ethnic and Asian subgroups, these improvements do not compensate for the large increases in death rates in 2020. All major Asian subgroups except Japanese experienced greater losses of life in 2019-2020 as well as cumulatively (2019-2021) than Whites, with Vietnamese, Filipinos, and other South/Southeast Asians having suffered the largest declines in life expectancy among non-Hispanic Asians. Vietnamese and other Southeast Asians experienced the greatest cumulative losses across all racial/ethnic groups except Native Americans. Our findings underscore the heterogeneity of loss in life expectancy within the Asian American population while identifying some of the risk factors that likely underlie this large variation.

Introduction The Omicron variant of the SARS-CoV-2 virus is described as more contagious than previous variants. We sought to assess risk to healthcare workers (HCWs) caring for patients with COVID-19 in surgical/obstetrical settings, and the perception of risk amongst this group. Methods From January to April, 2022, reverse transcription polymerase chain reaction was used to detect the presence of SARS-CoV-2 viral RNA in patient, environmental (floor, equipment, passive air) samples, and HCWs masks (inside surface) during urgent surgery or obstetrical delivery for patients with SARS-CoV-2 infection. The primary outcome was the proportion of HCWs masks testing positive. Results were compared with our previous cross-sectional study involving obstetrical/surgical patients with earlier variants (2020/21). HCWs completed a risk perception electronic questionnaire. Results 11 patients were included: 3 vaginal births and 8 surgeries. 5/108 samples (5%) tested positive (SARS-CoV-2 Omicron) viral RNA: 2/5 endotracheal tubes, 1/22 floor samples, 1/4 patient masks and 1 nasal probe. No samples from the HCWs masks (0/35), surgical equipment (0/10) and air samples (0/11) tested positive. No significant differences were found between the Omicron and 2020/21 patient groups positivity rates (Mann-Whitney U test, p = 0.838) or the level of viral load from the naso-pharyngeal swabs (p = 0.405). Nurses had a higher risk perception than physicians (p = 0.0377). Conclusion No significant difference in contamination rates were found between SARS-CoV-2 Omicron BA.1 and previous variants in surgical/obstetrical settings. This is reassuring as no HCW mask was positive and no HCW tested positive for COVID-19 post-exposure.

Importance: The origin of highly divergent “cryptic” SARS-CoV-2 Spike sequences, which appear in wastewater but not clinical samples, is unknown. These wastewater sequences have harbored many of the same variants that later emerged in Omicron. If these enigmatic sequences are human-derived and transmissible, they could both be a source of future variants and a valuable tool for forecasting sequences that should be incorporated into vaccines and therapeutics. Objective: To determine whether enigmatic SARS-CoV-2 lineages detected in wastewater have a human or non-human (i.e., animal) source. Design: On January 11, 2022, an unusual Spike sequence was detected in municipal wastewater from a metropolitan area. Over the next four months, more focused wastewater sampling resolved the source of this variant. Setting: This study was performed in Wisconsin, United States, which has a comprehensive program for detecting SARS-CoV-2 in wastewater. Participants: Composite wastewater samples were used for this study; therefore, no individuals participated. Main Outcome(s) and Measure(s): The primary outcome was to determine the host(s) responsible for shedding this variant in wastewater. Both human and non-human hosts were plausible candidates at the study9s outset. Results: The presence of the cryptic virus was narrowed from a municipal wastewater sample (catchment area >100,000 people) to an indoor wastewater sample from a single facility (catchment area ~30 people), indicating the human origin of this virus. Extraordinarily high concentrations of viral RNA (~520,000,000 genome copies / L and ~1,600,000,000 genome copies / L in June and August 2022, respectively) were detected in the indoor wastewater sample. The virus sequence harbored a combination of fixed nucleotide substitutions previously observed only in Pango lineage B.1.234, a variant that circulated at low levels in Wisconsin from October 2020 to February 2021. Conclusions and Relevance: High levels of persistent SARS-CoV-2 shedding from the gastrointestinal tract of an infected individual likely explain the presence of evolutionarily advanced, “cryptic variants” observed in some wastewater samples.

This cross-sectional study investigated health management, well-being, and pandemic-related perspectives in Shanghainese adults ≥50 years during early and strict COVID-19 control measures. A self-report survey was administered via Wenjuanxing between March-April/2020. Items from the Somatic Symptom Scale, Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 were administered, as well as pandemic-specific questions. 1181 primarily married, retired females participated; Many had hypertension (n=521, 44.1%), coronary artery disease (CAD; n=201, 17.8%) and diabetes (n=171, 14.5%). While most respondents (n=868; 73.5%) were strictly following control measures (including limiting visits with children; n=390, 33.0%) and perceived they could tolerate that beyond 6 months (n=555;47.0%), they were optimistic about the future if control measures were continued (n=969;82.0%), and perceived impact would be temporary (n=646;64.7%). 52 of those with any condition (8.2%) and 19 of those without a condition (3.5%) reported the pandemic was impacting their health. Somatic symptoms were high (29.4+/-7.1/36), with Sleep & Cognitive symptoms highest. 24.4% and 18.9% of respondents had elevated depressive and anxious symptoms, respectively; greater distress was associated with lower income (p=0.018), having hypertension (p=0.001) and CAD (p<0.001), more negative perceptions of global COVID-19 control (p=0.004), COVID-19 spread (p≤0.001), impact on life and health (p<0.001), compliance with control measures (p<0.001), and shorter time control measures could be tolerated (p<0.001) in adjusted analyses. In the initial COVID-19 outbreak, most older adults were optimistic and resilient with regard to the epidemic and control measures. However, the distress of older adults is not trivial, particularly in those with health issues.

Objective To verify the impact (effect) of the COVID-19 pandemic on the rates of reporting of interpersonal violence against children aged 0-11 years old in Salvador, Bahia, from 2020 to 2021. Methods The study used two epidemiological approaches: a) temporal aggregation and b) an individual cross section, based on cases of interpersonal violence against children reported in SINAN from 2009 to 2021. Annual rates of reporting of interpersonal violence against children (per 10,000) and percentages were calculated according to different strata of each variable of interest. The temporal trend was analyzed using the simple linear regression method (R2=0.6955) applied to the rates from 2014 to 2019, the period in which they showed the most consistency. Results The rates of reporting of violence against children showed a large variation, with a mean of 4.7/10,000. In 2021, the rate was 7/10,000 (a 45.8% increase on the previous year). Regression analysis indicated a mean reduction of 0.337/10,000 a year, and expected rates of 4.62 and 4.28/10,000, respectively, for 2020 and 2021. Conclusion The occurrence of COVID-19 and, particularly, the increase in the number of reported cases of interpersonal violence against children in the second year of the pandemic in Bahia suggest that these events may be directly or indirectly related. More robust studies are needed to confirm this relationship.

Near-term probabilistic forecasts for infectious diseases such as COVID-19 and influenza play an important role in public health communication and policymaking. From 2013-2019, the FluSight challenge run by the Centers for Disease Control and Prevention invited researchers to develop and submit forecasts using influenza-like illness (ILI) as a measure of influenza burden. Here we examine how several statistical models and an autoregressive neural network model perform for forecasting ILI during the COVID-19 pandemic, where historical patterns of ILI were highly disrupted. We find that the autoregressive neural network model which forecasted ILI well pre-COVID still performs well for some locations and forecast horizons, but its performance is highly variable, and performs poorly in many cases. We found that a simple exponential smoothing statistical model is in the top half of ranked models we evaluated nearly 75% of the time. Our results suggest that even simple statistical models may perform as well as or better than more complex machine learning models for forecasting ILI during the COVID-19 pandemic. We also created an ensemble model from the limited set of time series forecast models we created here. The limited ensemble model was rarely the best or the worst performing model compared to the rest of the models assessed, confirming previous observations from other infectious disease forecasting efforts on the less variable and generally favorable performance of ensemble forecasts. Our results support previous findings that no single modeling approach outperforms all other models across all locations, time points, and forecast horizons, and that ensemble forecasting consortia such as the COVID-19 Forecast Hub and FluSight continue to serve valuable roles in collecting, aggregating, and ensembling forecasts using fundamentally disparate modeling strategies.

Objective: To investigate temporal trends, severe outcomes, and rebound among systemic autoimmune rheumatic disease (SARD) patients according to outpatient SARS-CoV-2 treatment. Methods: We performed a retrospective cohort study investigating outpatient SARS-CoV-2 treatments among SARD patients at Mass General Brigham (23/Jan/2022-30/May/2022). We identified SARS-CoV-2 infection by positive PCR or antigen test (index date=first positive test) and SARDs using diagnosis codes and immunomodulator prescription. Outpatient treatments were confirmed by medical record review. The primary outcome was hospitalization or death within 30 days following the index date. COVID-19 rebound was defined as documentation of negative then newly-positive SARS-CoV-2 tests. The association of any vs. no outpatient treatment with hospitalization/death was assessed using multivariable logistic regression. Results: We analyzed 704 SARD patients with COVID-19 (mean age 58.4 years, 76% female, 49% with rheumatoid arthritis). Treatment as outpatient increased over calendar time (p<0.001). A total of 426(61%) received outpatient treatment: 307(44%) with nirmatrelvir/ritonavir, 105(15%) with monoclonal antibodies, 5(0.7%) with molnupiravir, 3(0.4%) with outpatient remdesivir, and 6(0.9%) with combinations. There were 9/426 (2.1%) hospitalizations/deaths among those treated as outpatient compared to 49/278 (17.6%) among those with no outpatient treatment (adjusted odds ratio [aOR] 0.12, 0.05 to 0.25). 25/318 (8%) of patients who received oral outpatient treatment had documented COVID-19 rebound. Conclusion: Outpatient treatment was strongly associated with lower odds of severe COVID-19 compared to no outpatient treatment. At least 8% of SARD patients experienced COVID-19 rebound. These findings highlight the importance of outpatient COVID-19 treatment for SARD patients and the need for further research on rebound.

Background: Wrist-worn devices can keep track of a persons daily health status, including those likely to become infected with the SARS-CoV-2 virus. Technological solutions using mobile devices are being developed to predict the time course of COVID-19. Objective: In this proof-of-concept study, we use heart rate data to detect the first sign of infection in people who have been diagnosed with COVID-19 and to monitor the time-course of the illness. Methods: The heart-rate data were analysed using a multiplicative cascade driven by a Gaussian process. This provides two parameters, mean and standard deviation, which when combined with similar parameters estimated from control series, provide a Health Index. Results: For 90% of 31 cases, the Health Index tracked COVID-19 infection with the virus and subsequent recovery. The first sign of COVID-19 was detected on average nine days before symptoms were reported. Conclusions: Early detection of COVID-19 may lead to a reduction in the spread of the virus. The Heath Indexs potential use for the early detection of complications arising from Long COVID would be an important innovation.
