Disruption of seasonal enterovirus and parechovirus detections in the CSF and plasma of children during the COVID-19 pandemic

BACKGROUND

Enteroviruses (EV) and parechovirus (PeV) are a common cause of CNS infection in children. Both viruses demonstrate consistent seasonal patterns, with detections mainly in the summer-fall months. While research has shown COVID-19 pandemic-related disruption of traditional seasonality of respiratory pathogens, the pandemic's impact on non-respiratory pathogens is less understood. The aim of this study was to quantify the EV/PeV seasonal variations during pre-COVID years compared to variations observed during the COVID pandemic.

METHODS

Patients with EV/PeV testing of CSF/plasma between January 2012 through September 2022 were identified. Restricted cubic spline methods were used to model the detections. Poisson models were utilized to model pre-COVID (2012-2019) EV/PeV detections. The expected seasonal trends from these models were then compared to the observed EV/PeV detections during the COVID pandemic (2020-2022).

RESULTS

A total of 5199 patients were included. The annual pre-pandemic proportion of EV detections ranged between 7.5%-20.3%. PeV exhibited a biennial pattern with peak proportions between 8.0%-16.3%. EV/PeV detections during the COVID pandemic period, especially during 2020 and 2021, were considerably lower than would have been expected based on pre-pandemic modeling. However, PeV detections from January through September 2022 nearly reached the pre-pandemic modeled expectation, including instances of exceeded expectations.

CONCLUSIONS

A significant disruption in expected seasonal EV/PeV detections was observed during the early phases of the COVID-19 pandemic. However, testing that occurred during summer-fall of 2022, when social mitigation initiatives were relaxed, showed a rapid increase in detections. Additional data are needed to further understand which public health initiatives are effective at decreasing EV/PeV transmission.

Socially, Culturally and Spiritually Sensitive Public Health Palliative Care Models in the Lower-income Countries: An Integrative Literature Review

The demand for palliative care (PC) is ever-increasing globally. The emergence of COVID-19 pandemic has further accelerated the need for PC. In the lower-income countries (LICs), where PC need is highest, PC, the most humane, appropriate and realistic approach to care for patients and families affected by life-limiting illness, is minimal or non-existent. Recognising the disparity between high, middle and LICs, the World Health Organization (WHO) has recommended public health strategies for PC within the socioeconomic, cultural and spiritual contexts of individual countries. This review aimed to: (i) identify PC models in the LICs utilising public health strategies and (ii) characterise how social, cultural and spiritual components were integrated into these models. This is an integrative literature review. Thirty-seven articles were included from a search of four electronic databases - Medline, Embase, Global Health and CINAHL. Literature, both empirical and theoretical literature, published in English from January 2000 to May 2021 that mentioned PC models/services/programmes integrating public health strategies in the LICs were included in the study. A number of LICs utilised public health strategies to deliver PC. One-third of the selected articles highlighted the importance of integrating sociocultural and spiritual components into PC. Two main themes - WHO-recommended public health framework and sociocultural and spiritual support in PC and five subthemes - (i) suitable policies; (ii) availability and accessibility of essential drugs; (iii) PC education for health professionals, policymakers and the public; (iv) implementation of PC at all levels of healthcare and (v) sociocultural and spiritual components, were derived. Despite embracing the public health approach, many LICs encountered several challenges in integrating all four strategies successfully.

Effective factors in people's preventive behaviors during covid-19 pandemic: a systematic review and meta-synthesis

Background

The overwhelming outbreak of covid-19 has forced governments all over the world to consider different measures to face this challenging situation. A vitally important element to the declining transmission of viruses is changing behaviors based on reliable information. This study was designed and implemented to identify factors affecting the preventive behaviors during the covid-19 pandemic.

Methods

This thematic synthesis was carried out in order to create a set of central themes that summarize all of the issues raised in the articles reviewed in this study. We used PRISMA 2020 guidelines to direct this systematic review and meta synthesis. The process of analyzing data includes three different stages: 1) creating codes; 2) production of descriptive themes; 3) and finally, the creation of analytical themes. The Standards for Reporting Qualitative Research checklist was used to evaluate the articles' quality.

Results

Five central themes emerged from 8 included articles, (1) Social factors (subthemes: environmental context, political leadership, multimedia), (2) Cultural factors (subthemes: national culture, religious culture, the family beliefs, work culture, foreign culture), (3) Economic factors (subthemes: economic situation of the individual, the government supports, infrastructures), (4) Personal factors (subthemes: people experiences, cognitive ability, physical factors, different motivational level, sense of responsibility, risk management, and self-management skills), and (5) Knowledge and Education factors (subthemes: access to information, skill training). Furthermore, SRQR items that were weakly reported were “researcher characteristics and reflexivity”, “Sampling strategy”, “Data collection methods”, “Data analysis”, and “techniques to enhance trustworthiness.

Conclusion

Health policymakers and other public health officials in various countries can use the factors listed to develop appropriate, evidence-based policies. They should investigate behavioral characteristics in their community based on their abilities, and then design and implement appropriate executive actions.

The impact of COVID-19 vaccination delay: A data-driven modeling analysis for Chicago and New York City

Background

By the beginning of December 2020, some vaccines against COVID-19 already presented efficacy and security, which qualify them to be used in mass vaccination campaigns. Thus, setting up strategies of vaccination became crucial to control the COVID-19 pandemic.

Methods

We use daily COVID-19 reports from Chicago and New York City (NYC) from 01-Mar2020 to 28-Nov-2020 to estimate the parameters of an SEIR-like epidemiological model that accounts for different severity levels. To achieve data adherent predictions, we let the model parameters to be time-dependent. The model is used to forecast different vaccination scenarios, where the campaign starts at different dates, from 01-Oct-2020 to 01-Apr-2021. To generate realistic scenarios, disease control strategies are implemented whenever the number of predicted daily hospitalizations reaches a preset threshold.

Results

The model reproduces the empirical data with remarkable accuracy. Delaying the vaccination severely affects the mortality, hospitalization, and recovery projections. In Chicago, the disease spread was under control, reducing the mortality increment as the start of the vaccination was postponed. In NYC, the number of cases was increasing, thus, the estimated model predicted a much larger impact, despite the implementation of contention measures.

The earlier the vaccination campaign begins, the larger is its potential impact in reducing the COVID-19 cases, as well as in the hospitalizations and deaths. Moreover, the rate at which cases, hospitalizations and deaths increase with the delay in the vaccination beginning strongly depends on the shape of the incidence of infection in each city.

[Reducing sugar consumption to improve oral health-which strategies are effective?]

Strategien zur Gesundheitsförderung können einen wesentlichen Beitrag leisten, um nichtübertragbare chronische Krankheiten zu verhindern. Die wesentlichen nichtübertragbaren Erkrankungen in der Zahnmedizin sind Zahnkaries und Parodontalerkrankungen. Zucker spielt sowohl bei der Entstehung von Zahnkaries als auch von Übergewicht und dessen Folgen für die Allgemeingesundheit eine ursächliche Rolle und ist daher als wichtige kommerzielle Gesundheitsdeterminante mehr und mehr ins Blickfeld von Wissenschaft und Gesundheitspolitik gerückt. Existierende Strategien zur Reduktion des Zuckerkonsums zielen jedoch häufig auf Maßnahmen zur individuellen Verhaltensänderung ab und lassen dabei die Rolle von gesellschaftlichen und kommerziellen Einflüssen außer Acht.

In diesem Artikel beschreiben wir die aktuellen Empfehlungen der Weltgesundheitsorganisation (WHO) zum Zuckerkonsum, Daten zum Zuckerverzehr in Deutschland sowie die sozialen und kommerziellen Faktoren, welche den Zuckerkonsum beeinflussen. Grundlegende Prinzipien der Gesundheitsförderung werden dargelegt und sich daraus ergebende Strategien zur Zuckerreduzierung diskutiert. Dabei werden konkrete Beispiele für Upstream- und Downstream-Ansätze benannt und Möglichkeiten der Einflussnahme durch die zahnmedizinische Community in Politik und Praxis aufgezeigt.

The macroecology of cancer incidences in humans is associated with large-scale assemblages of endemic infections

It is now well supported that 20% of human cancers have an infectious causation (i.e., oncogenic agents). Accumulating evidence suggests that aside from this direct role, other infectious agents may also indirectly affect cancer epidemiology through interactions with the oncogenic agents within the wider infection community. Here, we address this hypothesis via analysis of large-scale global data to identify associations between human cancer incidence and assemblages of neglected infectious agents. We focus on a gradient of three widely-distributed cancers with an infectious cause: bladder (~2% of recorded cancer cases are due to Shistosoma haematobium), liver (~60% consecutive to Hepatitis B and C infection) and stomach (Helicobacter pylori is associated with ~70% of cases). We analyzed countries in tropical and temperate regions separately, and controlled for many confounding social and economic variables. First, we found that particular assemblages of bacteria are associated with bladder cancer incidences. Second, we observed a specific and robust association between helminths and liver cancer incidences in both biomes. Third, we show that certain assemblages of viruses may facilitate stomach cancer in tropical area, while others protect against its development in temperate countries. Finally, we discuss the implications of our results in terms of cancer prevention and highlight the necessity to consider neglected diseases, especially in tropics, to adapt public health strategies against infectious diseases and cancer.
