Stress in healthcare workers in Hospitals and Emergency Care Units in Sergipe public health service during COVID-19 pandemic time

The objective of this work was to assess the stress in healthcare workers (HCW) and its correlation with perception of stressors in their work environments - hospitals and emergency care units in the public health system in the state of Sergipe, Brazil, during the COVID-19 pandemic. This is a cross-sectional study carried out by non-probabilistic sampling with 58 HCW, using specific questionnaires and a validated scale (Job Stress Scale) about sociodemographic issues, job stress and COVID-19. Using the demand-control-support assessment model, the work performed was classified as passive, active, low strain and high strain, according work's demand and the range of decision-making freedom. Estimated correlations between each questionnaire were performed using Pearson's correlation coefficient through SPSS software, and descriptive statistics, through Excel. Most of the participants were shown to be under high psychological demand (93.10%) and found themselves with high control (89.66%). Some factors affected the HCW’s perception of social support in the workplace, these were their team’s knowledge about COVID-19, the availability of personal protective equipment, and their physical comfort while using it. HCW were involved in active work; although they were not in the worst scenario in relation to psychological stress, they were still under great psychological strain, which reinforces the need to adopt effective measures to reduce it.

Smart Dressings for Wound Healing: A Review

OBJECTIVE

To provide an overview of sensors incorporated into wound dressings that can be used to assess and manage healing parameters.

DATA SOURCES

Authors conducted an extensive literature search of the Science Direct, Scopus, MEDLINE-PubMed, and Web of Science databases.

STUDY SELECTION

A total of 587 studies that evaluated dressings used to manage wound healing parameters were identified in the search, but only 16 met all of the review criteria and were included in the final analysis.

DATA EXTRACTION

Chronic wounds were the most common type of injury among studies. Six articles involved a wireless transmission system.

DATA SYNTHESIS

All studies evaluated the physical and chemical characteristics of the dressings.

CONCLUSIONS

This review demonstrates the lack of studies examining wound dressing sensors. New studies are required to assess sensors that allow not only wound monitoring, but also the application of drugs in a single dressing, providing a better and more cost-effective treatment for wounds.

Inflammatory modulation of fluoxetine use in patients with depression: A systematic review and meta-analysis

There is growing evidence that there is a relationship between major depressive disorder (MDD), also simply known as "depression", and inflammatory processes. Selective serotonin inhibitors, such as fluoxetine, are used as a first-line treatment for depression, and it is hypothesized that its use can reduce levels of proinflammatory cytokines. The aim of this systematic review and meta-analysis is to enable a better understanding of how treatment with the antidepressant fluoxetine modulates inflammation, and the roles of the main cytokines in this process. Risk of bias (RoB) in the included studies was assessed using the Cochrane Risk of Bias Assessment tool for Non-randomized studies (RoBANS). In the meta-analysis, standardized mean difference (SMD) was used as a summary statistic and grouped statistics using the generic inverse variation method in RevMan 5 with random effects model. Heterogeneous changes in cytokine levels were also evaluated from the SMD forest plot of individual studies. After analysis, we observed that fluoxetine was able to decrease TNF-α levels (SMD ± 0.90, 95% CI = 0.16, 1.165, Z ± 2.40, p = 0.02), but not change IL-6 levels (SMD ± 0.37, 95% CI = 0.21, 0.95, Z ± 1.25, p = 0.21).Fluoxetine acts by modulating neuroimmunology, and not only by acting only on the independent restoration of neurotransmission and neuroinflammation pathways.
