ABSTRACT

BACKGROUND: The world's population changed with the emergence of the SARS-CoV-2 pandemic. Burnout arises due to overwork, prolonged work periods, a lack of human and material resources, etc. Several studies have reported the incidence of burnout syndrome in nurses that work in intensive care units (ICUs). The aim was to map the scientific evidence related to nurses' burnout in the ICU, namely the repercussions of SARS-CoV-2 in terms of burnout among nurses. METHODS: A scoping review followed the Joanna Briggs Institute methodology guidelines to search for and synthesise studies published between 2019 and 2022. The databases searched were MEDLINE, CINAHL, LILACS, SCOPUS, PsycINFO and OPEN GREY. A total of fourteen articles were eligible to be included. RESULTS: A content analysis of the selected articles was carried out, and three categories emerged that corresponded to the dimensions of burnout according to Maslach and Leiter: emotional exhaustion, depersonalisation dimension and a lack of personal accomplishment. It was evident that nurses who worked in the ICU during the pandemic showed high levels of burnout. CONCLUSIONS: It is recommended that hospital administrations hire health professionals, namely nurses, as a strategic and operational management strategy to reduce the risk of increased burnout during pandemic outbreaks.

ABSTRACT

The pandemic caused by Sars-CoV-2 is a viral infection that has generated one of the most significant health problems worldwide. Previous studies report the main protease (Mpro) as a potential target for this virus, as it is considered a crucial enzyme in mediating replication and viral transcription. This work presented the construction of new bioactive compounds for possible inhibition. The De novo molecular design of drugs method in the incremental construction of a ligant model within a receptor model was used, producing new structures with the help of artificial intelligence. The research algorithm and the scoring function responsible for predicting orientation and affinity in the molecular target at the time of coupling showed, as a result of the simulation, the compound with the highest bioaffinity value, Hit 998, with the energy of -17.62 kcal/mol, and synthetic viability close to 50%. While hit 1103 presented better synthetic viability (80%), its affinity energy of -10.28 kcal/mol. Both were compared with the reference linker N3, with a binding affinity of -7.5 kcal/mol. ADMET tests demonstrated that simulated compounds have a low risk of metabolic activation and do not exert effective distribution in the CNS, suggesting a pharmacokinetic mechanism based on local action, even with high topological polarity, which resulted in low oral bioavailability. In conclusion, MMGBSA, H-bonds, RMSD, SASA, and RMSF values were also obtained through molecular dynamics to verify the stability of the receptor-ligant complex within the active protein site to seek new therapeutic propositions in the fight against the pandemic.Communicated by Ramaswamy H.

ABSTRACT

Polysaccharides arouse great interest due to their structure and unique properties, such as biocompatibility, biodegradability, and absence of toxicity. Polysaccharides from marine sources are particularly useful due to the wide variety of applications and biological activities. Chitosan, a deacetylated derivative of chitin, is an example of an interesting bioactive marine-derived polysaccharide. Moreover, a wide variety of chemical modifications and conjugation of chitosan with other bioactive molecules are responsible for improvements in physicochemical properties and biological activities, expanding the range of applications. An overview of the synthetic approaches for preparing chitosan, chitosan derivatives, and conjugates is described and discussed. A recent update of the biological activities and applications in different research fields, mainly focused on the last 5 years, is presented, highlighting current trends.

ABSTRACT

Coronavirus disease (COVID-19) has the virus that causes the SARS-CoV-2 severe acute respiratory syndrome, which has reached a pandemic proportion, with thousands of deaths worldwide already registered. It has no standardized effective clinical treatment, arousing the urgent need for the discovery of bioactive compounds for the treatment of symptoms of COVID-19. In this context, the present study aimed to evaluate the influence of seasonality on the yield and chemical composition of the essential oils of Piper cernuum and Piper rivinoides as well as to evaluate the anti-SARS-CoV-2 potential of the major components of each oil by molecular docking and quantum chemical calculation (Density Functional Theory method), being possible indicate that the winter and autumn periods, the seasons of the year where it is possible to obtain the highest percentage of Piper cernuum and Piper rivinoides oils, respectively. Regarding the anti-SARS-Cov-2 potential, the present work showed that the dihydroagarofuran present in Piper cernuum, presented a strong interaction with amino acid residues from Mpro, presenting a potential similar to Remdesivir, a drug for clinical use. Regarding methyltransferase, dihydroagarofuran (Piper cernuum) and myristicin (Piper rivinoids) showed better affinity, with important interactions at the active site of the inhibitor Sinefugin, suggesting a potential inhibitory effect of the heterodimer methyltransferase complex NSP16-NSP10 SARS Cov-2. Molecular docking and molecular dynamics studies represent an initial step, being indicative for future in vitro studies of dihydroagarofuran and myristicin, as possible pharmacological tools for COVID-19.

ABSTRACT

El mundo, como lo conocíamos, habrá experimentado transformaciones irreversibles luego de la pandemia ocasionada por la COVID-19, con impactos en diversos ámbitos y repercusiones para la sociedad en el largo plazo. Ningún otro evento acontecido en las últimas décadas tendrá un impacto social, económico y psicológico tan globalizado y difundido (1). En efecto, en ninguna parte del mundo se podrá decir que no hubo víctimas a causa de esta tragedia. Así mismo, lejos de este presente, podremos observar cambios en el futuro. Pero, ¿será posible calcular los efectos de la pandemia en nuestra vida a largo plazo? ¿Qué cambiará? De hecho, algunos de estos cambios podrán volverse permanentes, como la utilización de recursos a distancia, en nuestro caso, en el ámbito de la salud, como respuesta a los innumerables retos asociados a esta emergencia sanitaria.

ABSTRACT

Neurological symptoms in COVID-19 patients can also be found in the pediatric population, but they are usually described as mild symptoms. Herein, we described a case series of four pediatric patients with severe and highly heterogeneous central and peripheral nervous system manifestations. The objective was to report neurological manifestations of COVID-19 in children and adolescents. The design is case series. The participants are four children and adolescents with confirmed COVID-19. The main outcome and measures are as follows: Clinical data were gathered from electronic medical records, and data of all neurologic symptoms were checked by a trained neurologist. We reported four pediatric patients with COVID-19 and different neurologic symptoms. Case 1 was a 16-year-old girl with a sensory and motor polyradiculopathy with RT-qPCR for COVID-19 and dengue both detected in CSF that improved after appropriate treatment. Case 2 was a 15-year-old boy with Guillain-Barre syndrome and had good response after using human immunoglobulin. Case 3 was a 5-year-old girl with acute intracranial hypertension that improved after going through lumbar puncture and using acetazolamide. Case 4 was a 2-month-old male infant with focal epileptic seizures that recovered after antiepileptic treatment. We highlight the need to consider different neurologic manifestations as part of the COVID-19 clinical spectrum.

ABSTRACT

AIM: This study aimed to identify which strategies are being adopted to deal with family restrictions in health units and assess nurses' perceptions of including families in nursing care during the current pandemic. BACKGROUND: Due to the COVID-19 pandemic, health organisations limited access for visitors. INTRODUCTION: Family centred care needs to be guaranteed, and alternatives for face-to-face interaction should be fostered. Therefore, there is an urgent need to rethink the family in nursing care during a pandemic. METHODS: We conducted a descriptive exploratory mixed-method study in Portugal using an electronic questionnaire. The study included 192 nurses recruited using a non-probabilistic convenience sample. The study was reported using the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. RESULTS: A total of 41.1% of participants (n = 79) reported that visits to their services were not authorised, and 66.7% (n = 128) reported resorting to video calls because of the restrictions imposed. Regarding attitude assessment, the average score of the scale was 77.9 (SD = 10.0), ranging between 26 and 98. When analysing the different dimensions of the 'Families' Importance in Nursing Care - Nurses Attitudes' scale, family data stand out as a burden. CONCLUSION: Although a large percentage of participants had a positive attitude towards families and tried to find strategies to maintain family centred care, many nurses still considered the family as a burden. The current COVID-19 pandemic may have aggravated this perception. IMPLICATIONS FOR NURSING PRACTICE, NURSING POLICY AND HEALTH POLICY: The continued implementation of family centred nursing practice is essential for child-well-being, including during the current pandemic. Therefore, having intervention policies with alternative forms of care is highly recommended.

ABSTRACT

Background & Aim: This Covid-19 pandemic represents a threat and a crisis for families' well-being. According to the Olson Circumplex Model, this study aimed to assess the family functioning through the components of cohesion and adaptability of Portuguese families during this pandemic. Methods & Materials: This is a descriptive, exploratory, and correlational study. A nonprobabilistic and convenience sample consisted of 376 people. Sociodemographic data, the family's characterization, the type of housing, the Vital Duvall cycle phase was collected from the participants, and FACES II was used to assess family cohesion and adaptability. The reliability of this instrument is high. The instruments for data collection were organized and sent through Google® forms, including the Informed Consent Form. The data were analyzed by SPSS-26 software using non-parametric tests were used for inferential analysis. Results: The results showed that 14,6% have a disengaged family cohesion;7,4% have a very rigid dimension in family adaptability, and about the type of family, 6,1% have an unbalanced dimension. Conclusion: Although on average, the participants have a connected family cohesion and family flexible adaptability, many participants have extreme values, under which it will be necessary to intervene. It is a priority for family nursing to understand the experience of families living in this current social, economic, and health context.

ABSTRACT

The COVID-19 pandemic represents a global threat and crisis situation, and its wide-reaching impact has also affected marital satisfaction. Dysfunction of the marital system puts the survival of the family unit at risk. This research aimed to determine the level of marital satisfaction of Portuguese families during the social lockdown and the association between the variables under study. A descriptive, exploratory study was conducted. During the social lockdown, 276 people of Portuguese nationality and residing in Portugal were recruited using nonprobabilistic convenience sampling. Marital satisfaction in the pandemic phase showed low values that may be associated with the social, economic, and political context experienced by the pandemic situation. Future research must be carried out in order to identify, prevent, and intervene in situations of violence. In addition, future research should explore not only marital satisfaction during the current pandemic but a more systemic assessment of marital relations during crises, expanding the impact of marital satisfaction in family functioning.

ABSTRACT

The role of digital pathology in remote reporting has seen an increase during the COVID-19 pandemic. Recently, recommendations had been made regarding the urgent need of reorganizing head and neck cancer diagnostic services to provide a safe work environment for the staff. A total of 162 glass slides from 109 patients over a period of 5 weeks were included in this validation and were assessed by all pathologists in both analyses (digital and conventional) to allow intraobserver comparison. The intraobserver agreement between the digital method (DM) and conventional method (CM) was considered almost perfect (κ ranged from 0.85 to 0.98, with 95% CI, ranging from 0.81 to 1). The most significant and frequent disagreements within trainees encompassed epithelial dysplasia grading and differentiation among severe dysplasia (carcinoma in situ) and oral squamous cell carcinoma. The most frequent pitfall from DM was lag in screen mirroring. The lack of details of inflammatory cells and the need for a higher magnification to assess dysplasia were pointed in one case each. The COVID-19 crisis has accelerated and consolidated the use of online meeting tools, which would be a valuable resource even in the post-pandemic scenario. Adaptation in laboratory workflow, the advent of digital pathology and remote reporting can mitigate the impact of similar future disruptions to the oral and maxillofacial pathology laboratory workflow avoiding delays in diagnosis and report, to facilitate timely management of head and neck cancer patients.

ABSTRACT

The sanitary emergency generated by the pandemic COVID-19, instigates the search for scientific strategies to mitigate the damage caused by the disease to different sectors of society. The disease caused by the coronavirus, SARS-CoV-2, reached 216 countries/territories, where about 20 million people were reported with the infection. Of these, more than 740,000 died. In view of the situation, strategies involving the development of new antiviral molecules are extremely important. The present work evaluated, through molecular docking assays, the interactions of 4'-acetamidechalcones with enzymatic and structural targets of SARS-CoV-2 and with the host's ACE2, which is recognized by the virus, facilitating its entry into cells. Therefore, it was observed that, regarding the interactions of chalcones with Main protease (Mpro), the chalcone N-(4'[(2E)-3-(4-flurophenyl)-1-(phenyl)prop-2-en-1-one]) acetamide (PAAPF) has the potential for coupling in the same region as the natural inhibitor FJC through strong hydrogen bonding. The formation of two strong hydrogen bonds between N-(4[(2E)-3-(phenyl)-1-(phenyl)-prop-2-en-1-one]) acetamide (PAAB) and the NSP16-NSP10 heterodimer methyltransferase was also noted. N-(4[(2E)-3-(4-methoxyphenyl)-1-(phenyl)prop-2-en-1-one]) acetamide (PAAPM) and N-(4-[(2E)-3-(4-ethoxyphenyl)-1-(phenyl)prop-2-en-1-one]) acetamide (PAAPE) chalcones showed at least one strong intensity interaction of the SPIKE protein. N-(4[(2E)-3-(4-dimetilaminophenyl)-1-(phenyl)-prop-2-en-1-one]) acetamide (PAAPA) chalcone had a better affinity with ACE2, with strong hydrogen interactions. Together, our results suggest that 4'-acetamidechalcones inhibit the interaction of the virus with host cells through binding to ACE2 or SPIKE protein, probably generating a steric impediment. In addition, chalcones have an affinity for important enzymes in post-translational processes, interfering with viral replication.
