Background
During COVID-19 pandemic, healthcare workers (HCWs) have had high workload and have been exposed to multiple psychosocial stressors. The aim of this study was to evaluate HCWs in terms of the relative contributions of socio-demographic and mental health variables on three burnout dimensions: personal, work-related, and client-related burnout.
Methods
A cross-sectional study was performed using an online questionnaire spread via social networks. A snowball technique supported by health care institutions and professional organizations was applied.
Results
A total of 2008 subjects completed the survey. Gender, parental status, marriage status, and salary reduction were found to be significant factors for personal burnout. Health problems and direct contact with infected people were significantly associated with more susceptibility to high personal and work-related burnout. Frontline working positions were associated with all three dimensions. Higher levels of stress and depression in HCWs were significantly associated with increased levels of all burnout dimensions. Higher levels of satisfaction with life and resilience were significantly associated with lower levels of all burnout dimensions.
Conclusions
All three burnout dimensions were associated with a specific set of covariates. Consideration of these three dimensions is important when designing future burnout prevention programs for HCWs.

The vaginal delivery of various drugs is well described and its relevance established in current medical practice. Alongside recent advances and achievements in the fields of pharmaceutical nanotechnology and nanomedicine, there is an increasing interest in the potential use of different nanocarriers for the delivery of old and new pharmacologically active molecules with either therapeutic or prophylactic purposes. Nanosystems of polymeric nature in particular have been investigated over the last years and their interactions with mucosal fluids and tissues, as well as genital tract biodistribution upon vaginal administration, are now better understood. While different applications have been envisioned, most of the current research is focusing in the development of nano-formulations with the potential to inhibit the vaginal transmission of HIV upon sexual intercourse. The present work focuses its discussion on the potential and perils of polymer-based nanocarriers for the vaginal administration of different pharmacologically active molecules.
A novel small enveloped RNA virus with the typical characteristic of the family to which it belongs, a crown, hence the name coronavirus, appeared in December 2019 in Wuhan, China, and subdued the world to its influence. The particular severity of the disease and higher mortality rates in patients with associated morbidities, including hypertension, obesity and diabetes, increases the concern over the consequences of this pandemic. In this review, the features of SARS-CoV-2 will be addressed, as well as the reasons why it poses a particular challenge to diabetic patients. We will also highlight the recent treatment strategies being explored to control this pandemic. Emerging evidence demonstrates that the correct management of diabetes in those patients infected with SARS-CoV-2 is of utmost importance for the viral disease progression, therefore, the importance of blood glucose control will also be addressed.
Despite
research efforts to discover new drugs for Parkinson treatment,
the majority of candidates fail in preclinical and clinical trials
due to inadequate pharmacokinetic properties, namely blood-brain barrier
permeability. Within the high demand to introduce new drugs to market,
nanotechnology can be used as a solution. Accordingly, PEGylated PLGA
nanoparticles (NPs) were used as a smart delivery carrier to solve
the suboptimal aqueous solubility, which precludes its use in in vivo
assays, of a potent, reversible, and selective monoamine oxidase B
inhibitor (IMAO-B) (coumarin C75, IC50 = 28.89 ± 1.18
nM). Long-term stable PLGA@C75 NPs were obtained by nanoprecipitation
method, with sizes around 105 nm and a zeta potential of −10.1
mV. The encapsulation efficacy was around 50%, achieving the final
C75 concentration of 807 ± 30 μM in the nanoformulation,
which corresponds to a therapeutic concentration 27828-fold higher
than its IC50 value. Coumarin C75 showed cytotoxic effects
at 50 μM after 48 and 72 h of exposure in SH-SY5Y, Caco-2, and hCMEC/D3 cell lines. Remarkably, no cytotoxic effects were
observed after nanoencapsulation. Furthermore, the data obtained from
the P-gp-Glo assay and the cellular uptake studies showed that C75
is a P-glycoprotein (P-gp) substrate having a lower uptake profile
in intestinal and brain endothelial cells. Moreover, it was shown
that this membrane transporter influences C75 permeability profile
in Caco-2 and hCMEC/D3 cells. Interestingly, PLGA
NPs inhibited P-gp and were able to cross intestinal and brain membranes
allowing the successful transport of C75 through this type of biological
barriers. Overall, this work showed that nanotechnology can be used
to solve drug discovery related drawbacks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
