ABSTRACT
Compared to other respiratory viruses, the proportion of hospitalizations due to SARS-CoV-2 among children is relatively low. While severe illness is not common among children and young individuals, a particular type of severe condition called multisystem inflammatory syndrome in children (MIS-C) has been reported. The aim of this prospective cohort study, which followed a group of individuals under the age of 19, was to examine the characteristics of patients who had contracted SARS-CoV-2, including their coexisting medical conditions, clinical symptoms, laboratory findings, and outcomes. The study also aimed to investigate the features of children who met the WHO case definition of MIS-C, as well as those who required intensive care. A total of 270 patients were included between March 2020 and December 2021. The eligible criteria were individuals between 0-18 with a confirmed SARS-CoV-2 infection at the Infectious Disease Hospital "Prof. Ivan Kirov"in Sofia, Bulgaria. Nearly 76% of the patients were <= 12 years old. In our study, at least one comorbidity was reported in 28.1% of the cases, with obesity being the most common one (8.9%). Less than 5% of children were transferred to an intensive care unit. We observed a statistically significant difference in the age groups, with children between 5 and 12 years old having a higher likelihood of requiring intensive care compared to other age groups. The median values of PaO2 and SatO2 were higher among patients admitted to the standard ward, while the values of granulocytes and C-reactive protein were higher among those transferred to the intensive care unit. Additionally, we identified 26 children who met the WHO case definition for MIS-C. Our study data supports the evidence of milder COVID-19 in children and young individuals as compared to adults. Older age groups were associated with higher incidence of both MIS-C and ICU admissions.Copyright © 2023 P. Velikov et al., published by Sciendo.
ABSTRACT
Objectives: We sought to evaluate 2-year outcome of V-V ECMO support for COVID-19 related severe respiratory failure in our center. Method(s): Retrospective analysis of 41 consecutive patients (73% male, mean age 51.6+/-14.2 years, mean BMI 35.1+/-12.5 kg/m2) with critical hypoxemic and/or hypercapnic refractory respiratory failure (mean P/F ratio 67.9+/-14.3 mmHg, mean pCO2 77.6.0+/-185.7 mmHg, Murray Score 3.71+/-0.4) on V-V ECMO support from October 2020 to January 2022 Results: With mean support duration of 234.4+/-63.2 hours, 29 patients (70.7%) were successfully weaned off. Finally, 19 of them (46.3%) were discharged home with good neurological outcome (CPC 1,2). During followup, 30-day, 6-, 12-, and 24 -month survival rate was 61.3%, 46.2%, 41.9%, and 41,9% respectively. In survivor group shorter symptoms onset to respiratory failure time (4+/-4.7 vs. 7+/-6.7 days, p=0.04), higher P/F ration (86+/-41.5 vs. 65+/-37.5 mmHg, p=0.04) and norepinephrine support (0.03+/-0.06 vs. 0.09+/-0.12 ug/kg/min, p=0.04), and lower IL-6 level (12.3+/-7.5 vs. 25.9+/-8.8 ng/l, p=0.03) p=0.01) were analysed before cannulation. Mean in-ICU stay and in-hospital stay in survivors;groups reached 32.5+/-27.7 days and 42.6+/-35.8 days, respectively. All long-term survivors (17 patients) complained about slight functional health limitation only with normal 6MWT (542.6+/- 89.2 min), near to normal spirometry parameters (FEV/VC 87+/-7.4%, DLCO 63.1+/-13.7%, KCO 82.,1+/-19.4%) and minimal neurological disability (CPC 1-2) Conclusion(s): 2-year outcome of V-V ECMO support in COVID-19 severe respiratory failure is acceptable even in the scope of low-volume ECMO centre. Reported functional status of long-term survivors was good despite the complicated and prolonged in-hospital stay. (Table Presented).
ABSTRACT
Introduction and Aim: Previously tension-type headache (TTH) was found to be highly prevalent among the general population worldwide, but the current data available were limited. Due to the COVID-19 pandemic, many life changes occurred to adapt to the situation, students started e-learning from home and their sleep quality (SQ) might be influenced. Physiotherapy and nursing students were studied as they are rarely being studied by researchers, information about them was very limited. This study aimed to determine the prevalence of TTH, SQ and the type of correlation between the two during the COVID-19 pandemic. Method(s): A cross-sectional study was conducted by sharing the online questionnaires composed of 2 main components: (i) Questionnaire formulated from diagnosing criteria for TTH of ICHD-3 (ii) Pittsburgh Sleep Quality Index (PSQI), to PS and NS students from higher education institutions in Klang Valley, Malaysia. Result(s): A total of 259 respondents were recruited in the study. The prevalence of TTH was 76.8% and SQ had a mean score of 5.12, which indicated poor SQ among PS and NS students, during the COVID-19 pandemic. Correlation between TTH and SQ was proved to be significant in this study (p=0.032, rs =0.133). Conclusion(s): High prevalence of TTH and poor SQ among PS and NS students during the COVID-19 pandemic was determined. There is a weak positive correlation between TTH and SQ during COVID-19 pandemic.Copyright © 2023, Indian Association of Biomedical Scientists. All rights reserved.
ABSTRACT
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has created severe medical and economic consequences worldwide since 2019. Tocilizumab is one of the therapies considered capable of improving the condition of patients with COVID-19. However, there is not much information about the best time to give tocilizumab. METHOD(S): This was an analytical study with a retrospective cohort design, using the data of 125 patients infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with signs of acute respiratory distress syndrome in Dr. Moewardi Hospital, Surakarta, from March to August 2020. We analyzed various available clinical data to see which factors into clinical improvement with tocilizumab therapy. RESULT(S): Most patients showed clinical improvement after administration of tocilizumab. During the follow-up period, 21 patients died despite tocilizumab therapy. Significant risk factors associated with the need for intubation were heart rate, neutrophil, lymphocyte, pH, PaCO2, and PO2. The most influential variable on the need for intubation without being associated with other risk factors was PaO2 (p = 0.003, Confidence Intervals 95%). CONCLUSION(S): Tocilizumab has a role in treating patients infected by SARS-CoV-2, preventing the need for intubation when given to patients in good saturation condition with oxygen supplementation without positive pressure (PaO2 >65mmHg;SpO2 >93%).Copyright © 2023 Septian Adi Permana, Adhrie Sugiarto, Sidharta Kusuma Manggala, Muhammad Husni Thamrin, Purwoko Purwoko, Handayu Ganitafuri.
ABSTRACT
Telemedicine is a modality which utilizes technology to provide and support health care across large distances. It has redefined the practices of medicine in many specialties and continues to be a boon for clinicians on many frontiers. Its role in the branch of anesthesia remains largely unexplored but has shown to be beneficial in all the three phases: pre-operative, intra-operative, and post-operative. Now time has come that anesthesiologists across the globe reassess their strategies and utilize the telemedicine facilities in the field of anesthesia.Copyright © 2021 EDP Sciences.

ABSTRACT
The aim of the research. To study clinical and laboratory features of the new coronavirus infection (COVID-19) in order to develop a model that would allow, taking the publicly available research methods into account, to carry out early diagnosis of severe community-acquired pneumonia against the background of the new coronavirus infection. Material and methods. A total of 82 COVID-19 patients who complied with inclusion and exclusion criteria were enrolled. Depending on the clinical severity, three study groups were formed: group 1 included 13 patients with uncomplicated COVID-19, group 2 consisted of 39 patients with non-severe forms of pneumonia that developed against COVID-19 and group 3 was comprised of 30 patients with COVID-19 complicated by severe pneumonia. The groups were comparable in age and gender. All patients underwent general clinical examination, laboratory tests, including general and biochemical blood analysis, as well as chest computed tomography. Results. The clinical picture in COVID-19 patients differed depending on the disease severity. Coughing and shortness of breath were more often observed in patients with severe pneumonia;sore throat, on the contrary, was more often noted in patients with uncomplicated COVID-19. On admission to the inpatient facility, patients with severe pneumonia had higher body temperature and respiratory rate, with simultaneous decrease in blood oxygen saturation. One half of the patients with severe pneumonia had hypertensive disease in medical history, and one third had ischaemic heart disease. As a rule, uncomplicated COVID-19 patients did not have ischaemic heart disease. It was found through laboratory analysis of blood that groups of patients significantly differed in the levels of neutrophils, lymphocytes, monocytes, basophils and eosinophils. Conclusion. The use of such clinical and laboratory data as acute respiratory failure, fever, the levels of neutrophils, monocytes, lymphocytes, eosinophils and basophils makes it possible to identify patients with more severe pneumonia against the background of COVID-19 even before chest computed tomography.

ABSTRACT
Objectives: Extracorporeal membrane oxygenation has been widely used in patients with severe respiratory failure due to Covid-19 infection. ECMO was initiated at ECMO center or implantation performed in regional hospitals and patients transferred to ECMO center for further treatment. The aim of the study was to evaluate characteristics and outcomes of patients retrieved with ECMO versus thoseimplanted in our institution. Method(s): Retrospective, single center study. Data of all Covid-19 patients, supported with ECMO from 2020.04.01 to 2022.06.01 in our institution were evaluated. Data of patients retrieved on ECMO to our hospital were compared with data of patients when ECMO support was initiated at our institution. Result(s): During Covid-19 pandemic 54 patients with severe respiratory failure were supported with ECMO. Out of them 24(44.4%) patients were retrieved on ECMO. In all patient VV configuration was used. There were no significant differences of preoperative characteristics between retrieved vs institutionally cannulated patients (mean age 44 +/- 16 vs 45 +/- 12 years, pre-ECMO arterial pO2 62 +/- 16 vs 66 +/- 14 mmHg, pre-ECMO mechanical ventilation 2.1 vs 2.2 days). The overall survival to hospital discharge was 32%, 33% in patients retrieved with ECMO vs 30% in the group of patients with ECMO implantation on site. Conclusion(s): Patient characteristics and hospital survival of patients who were retrieved with implanted ECMO to our ECMO center were comparable to those patients with ECMO implantation on site.
ABSTRACT
Objectives: The effectiveness of prone positioning (PP) under VV-ECMO for severe COVID-19 still be unclear. Until now, PP under VV-ECMO was often performed as the trump card for refractory hypoxemia and weaning off ECMO. On the other hand, PP has the effect of promoting homogenization of Lung aeration and leading to prevention of VILI. Combine use of early prone positioning together VV-ECMO may have synergy effects of ultra-lung protective strategy. In this study, we analyzed early PP cases under VV-ECMO for severe COVID-19 in our hospital and examined their efficacy and feasibility. Method(s): We performed a retrospective study of patients with SARS-CoV-2-induced ARDS submitted to early PP during VV-ECMO. During VVECMO, PP was considered in case of "Type-H transition in imaging findings (CT / LUS) " and cases that the physician deemed necessary. The lung aeration is evaluated by LUS before and after each PP. If there is a finding that the dorsal collapsed lung is improved through PP, it is implemented as effective, and it continued. Result(s): From April 2021 to August 2021, there were a total of 10 early PP cases under ECMO, and the age was (average) 56 years. ECMO was implanted with P/F 98 and Murray score 3.3 points, and PP was started 14 hours after the ECMO implantation. The average PP duration is 17.4 hours and PP performed 5.8 times per patient. Comparing blood gas and respiratory mechanics before and after PP showed a significant difference in PaCO2 (before: 46 +/- 8 vs after: 42 +/- 9, p = 0.02). Finally, there were 10 ECMO successful weaning (100%) and 8 surviving discharges (80%). No major complications were observed. Conclusion(s): Early PP under VV-ECMO for severe COVID-19 can be safely performed, and it is suggested that the synergy effect of ultra-lung protective strategy may be associated with a reduction of hospital mortality.
ABSTRACT
Aim: While recent evidence describes atypical outcomes of coronavirus disease 2019 (COVID-19) in elderly patients, the frequency of delirium and associated outcomes in elderly patients with COVID-19 (coronavirus disease 2019) infection undergoing emergency surgery are not well defined. This study aims to determine the effect of COVID-19 on postoperative delirium and postoperative death in elderly patients undergoing emergency surgery. Material(s) and Method(s): This descriptive and cross-sectional study was conducted in general surgery, orthopedics, and cardiovascular surgery clinics of a public hospital, including 30 days of follow-up between April 1 and May 1, 2021. All patients who were admitted to these clinics for emergency surgery intervention on these dates constituted the study population, while a total of 140 patients aged >=65 years, who met the study criteria, formed the sample of the study. Descriptive Characteristics Form and Nursing Delirium Screening Scale (Nu-DESC) were used as data collection tools in the study. SPSS 25.0 statistical program was used for data analysis. Result(s): Thirty (42.85%) of the SARS-CoV-2 positive (n=70) patients developed delirium in the study. 12.9% (n=18) of the patients died within 30 days of follow-up after surgery. There were 30 (69.8) of 70 SARS-CoV-2 positive patients who developed delirium, and 12 patients (25.5) died after testing positive for COVID-19, with a mean of 8.08T1.56 days within 30 days of admission. Discussion(s): These findings may lead to a poor clinical prognosis for COVID-19 infection delirium and postoperative death in patients over 65 years of age undergoing emergency surgery.Copyright © 2023, Derman Medical Publishing.

ABSTRACT
Introduction. The work of medical personnel in the extreme conditions of the COVID-19 pandemic is related to the impact of nervous and emotional labor tension, high visual loads, which contributes to the formation of fatigue and overwork and requires the attention of labor physiologists. The study aims to substantiate the methodology of physiological assessment of functional fatigue of medical workers during work in a covid hospital to determine the duration of periods of work in a pandemic. Materials and methods. Comprehensive physiological and hygienic studies of the medical staff of the covid hospital during 6 months of work were aimed at a physiological study of the state of the cardiovascular system with the study of the characteristics of the response to stress loads (ECG registration on a 12-channel electrocardiograph and continuously using Holter monitoring, determination of the vegetative Kerdo index and Kvass endurance coefficient), the study of psychological conditions, hygienic assessment of the intensity of the labor process. The researchers have studied the physiological state of the central nervous system and the visual analyzer according to generally accepted methods. The authors have studied the features of neurohumoral regulation (the main mediator of the stress-implementing system — cortisol) in medical workers. We have carried out a total of 1728 measurements of psychophysiological indicators. The scientists carried out statistical data processing of the received data using statistical programs Statistika 10, Microsoft Excel 2010. Results. The researchers found that indicators of the functional state of the cardiovascular system, reflecting the degree of adaptation of the body of medical workers to industrial activity, can be used to determine physiologically justified work periods in a pandemic, further accumulation of scientific data and risk assessment of medical workers. After four months of work in medical organizations with COVID-19, the formation of an unfavorable functional state in medical personnel is reflected in changes in ECG and systemic blood pressure, increased detrenability of the cardiovascular system, the predominance of sympathetic influences. Limitations. There are quantitative restrictions due to the number of medical staff of the hospital with COVID-19. Conclusion. Pronounced loads on the visual analyzer when watching video terminal screens against the background of nervous and emotional labor tension are the leading professional factors and determine the formation of the functional state of overwork (third degree) in the medical staff of the hospital with COVID-19.

ABSTRACT
Background: At our hospital, people with COVID-19 (coronavirus disease 2019) had a high rate of pulmonary barotrauma. Therefore, the current study looked at barotrauma in COVID-19 patients getting invasive and non-invasive positive pressure ventilation to assess its prevalence, clinical results, and features. Methodology: Our retrospective cohort study comprised of adult COVID-19 pneumonia patients who visited our tertiary care hospital between April 2020 and September 2021 and developed barotrauma. Result(s): Sixty-eight patients were included in this study. Subcutaneous emphysema was the most frequent type of barotrauma, reported at 67.6%;pneumomediastinum, reported at 61.8%;pneumothorax, reported at 47.1%. The most frequent device associated with barotrauma was CPAP (51.5%). Among the 68 patients, 27.9% were discharged without supplemental oxygen, while 4.4% were discharged on oxygen. 76.5% of the patients expired because of COVID pneumonia and its complications. In addition, 38.2% of the patients required invasive mechanical breathing, and 77.9% of the patients were admitted to the ICU. Conclusion(s): Barotrauma in COVID-19 can pose a serious risk factor leading to mortality. Also, using CPAP was linked to a higher risk of barotrauma.Copyright © 2021 Muslim OT et al.
ABSTRACT
In this chapter, we research how changes in learning tension because of the COVID-19 pandemic affect the learning capabilities of HR advisors in a geographically distributed public HR function. The primary research question is therefore: How do tensions related to learning among HR advisors in a health-sector trust change during the COVID-19 pandemic? Through a longitudinal study consisting of interviews, focus groups, observations, and document studies, we found that the different views with respect to the digital provision of HR services, as well as learning and development, created a tension between the centralized and decentralized HR advisors before the pandemic. During the COVID-19 pandemic, the preconditions for collaboration across the centralized and decentralized HR advisors were changed. Everyone had to work from home with a geographical distance to colleagues and users, combined with more frequent meetings in a crisis situation, which created a sense of unity and belonging. This led to a reduction in learning tensions and cognitive distance and changed the view of learning and development. The combination of a high tension before COVID-19, and a lower tension during COVID-19, was the balancing act that led to the HR advisors being able to learn from each other, even at a distance and be a relevant support in the innovation process. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
ABSTRACT
Background: We reviewed patients with COVID-19 ARDS managed with VV-ECMO support at our center from March 2020 until February 2022. Material(s) and Method(s): We extracted data from electronic health records (Metavision and DIPS). We registered premorbid health status, ventilator-settings before initiation of ECMO, the time-course, and hospital mortality. Result(s): Thirty patients were managed at our hospital, with a median age of 57.2 years (28-65) and median BMI 28 (22-40). No patient had any serious comorbidity. Twenty-two patients received non-invasive ventilation prior to intubation (1-10 days). The median time on ventilator were 8.0 days (1-19) prior to ECMO and median tidal volume was 5.8 mL/kg PBW (3.1-7.5). Hypoxemia (median PaO2-FiO2 ratio 8 kPa, range 6-12 kPa) and hypercapnia (median PaCO2 11.9 kPa, range 4.2-18.5) [SEP1] despite lung protective ventilation were the main indications for VV-ECMO. Two patients had severe respiratory acidosis without hypoxemia. 18 patients developed serious complications while managed with ECMO (acute renal failure, clinically significant bleeding, sepsis, right ventricular heart failure, dislocation of cannulae). Seven patients received renal replacement therapy. Sixteen patients (53%) died. Thirteen patients (43%) died on ECMO, three (10%) after weaning, Twelve (40%) were discharged from hospital, two are currently in ICU (7%). The median duration of ECMO and ventilator treatment, was 27 (6-50) and 37 (9-78) days, respectively. Conclusion(s): Management of patients with COVID-19 ARDS with VV-ECMO is very resource-intensive, and accompanied by serious complications and high mortality. In-hospital mortality in our cohort was 53%, which is comparable with reports from other centers. However, the duration of ECMO, and pre-ECMO mechanical ventilation, were longer than typically reported.
ABSTRACT
Foot reflexology is the use of massage and acupressure techniques on the feet, which represent each organ of the human body. The reflexologist knows precisely the anatomy of the body and the reflex points on the feet in order to relieve and treat the person's problems. A team from the University Hospital of Clermont-Ferrand shares a very positive experience, unfortunately interrupted by the Covid-19 health crisis.

Due to the global restrictions to decrease the risk of infection in classrooms, the transition from face-to-face education to distance learning was a necessity during the Covid-19 pandemic. Grounded in Self-Determination Theory, the present research sought to explore how the pandemic affects university students during distance learning. Specifically, the study examined the predictors of pressure/tension and attempted to identify the unique and mediator roles of correlates of pressure/tension of university students. This cross-sectional study was conducted with 432 university students from different departments of different universities in Turkey. The online survey was administered between the last week of October and the second week of December 2020. Our findings revealed that there is a positive association between pressure/tension and Covid-specific worry. Also, there is a negative association between learning climate and pressure/tension and between perceived competence and pressure/tension. Further, learning climate mediated the link between Covid-specific worry and pressure/tension. The data of the present study depends on students' academic (learning climate) and also non-academic (Covid worry) experiences during the pandemic. Methodological limitations concerning the research design are discussed.
ABSTRACT
Background: There is still no specific treatment strategy for COVID-19 other than supportive management. The potential biological benefits of ozone therapy include reduced tissue hypoxia, decreased hypercoagulability, modulated immune function by inhibiting inflammatory mediators, improved phagocytic function, and impaired viral replication. This study aimed to evaluate the effect of intravenous ozonated normal saline on patients with severe COVID-19 disease. Method(s): In this study, a single centralized randomized clinical trial was conducted on 80 hospitalized patients with severe COVID-19. The patients were selected by random allocation method and divided into two groups A and B. In group A (control group), patients were given standard drug treatment, and in group B (intervention group), patients received ozonated normal saline in addition to the standard drug treatment. In the intervention group, 400 mL of normal saline was weighed by 40 mug/ kg of body weight and was injected into patients within 15 to 30 minutes (80 to 120 drops per minute). This process was done daily every morning for a week. Primary and secondary outcomes of the disease included changes in the following items: length of hospital stay, inflammatory markers including C-reactive protein (CRP), clinical recovery, arterial blood oxygen status, improvement of blood disorders such as leukopenia and leukocytosis, duration of ventilator attachment, and rapid clearance of lung lesions on CT scans. The need for intensive care unit (ICU) hospitalization, the length of ICU stay, and the mortality rate in patients of the two groups was compared. Result(s): According to the results of the initial outcome variable analysis, the probability of discharge of patients who received the normal ozonated saline intervention was 33% higher than patients who did not receive this intervention;however, this relationship was not statistically significant (HR = 0.67, 95%, CI = 0.42-1.06, P value = 0.089). The chance of ICU hospitalization in patients of the intervention group was three times more than that of the comparison group, but this relationship was not significant (odds ratio = 4.4 95% CI = 1.32-14.50, P value = 0.016). The use of ozonated normal saline was found to increase the risk of death by 1.5 times but this relationship was not statistically significant (odds ratio = 1.5, 95% CI = .24-9.75, P value = 0.646). Ozonated normal saline had a significant effect on changes in respiration rate (in the intervention group the number of breaths was decreased) and the erythrocyte sedimentation rate (in the intervention group the erythrocyte sedimentation rate was increased);however, it had no significant effect on other indicators. Conclusion(s): The present study showed that ozone therapy in hospitalized patients with severe COVID-19 could help improve some primary and secondary outcomes of the disease. Governments and health policymakers should make ozone therapy an available care service so that the need for advanced treatment facilities decreases;consequently, this measure may improve patient safety, prevent lung tissue destruction, and control cytokine storms in patients. Additionally, health decision-makers need to aim for the effective clinical improvement of patients, especially severe ones, and the reduction of their mortality. However, further large-scale multicenter studies with larger sample sizes considering drug side effects and other variables influencing the clinical course of COVID-19 can provide more information on the effectiveness and importance of ozone therapy.Copyright © 2023 The Author(s);Published by Kerman University of Medical Sciences.
ABSTRACT
Patients with end-stage kidney disease undergoing hemodialysis have one of the highest COVID-19 mortality rates. The use of innovative methods capable of optimizing their treatment outcomes is important for clinical practice. Aims - to investigate the efficacy and safety of neutralizing monoclonal antibodies in COVID-19 patients treated with hemodialysis. Material and methods. We conducted a retrospective controlled single-center study with 102 COVID-19 patients on maintenance hemodialysis involved (M: 67;65.7%;W: 35;34.3%), aged 57.2+/-15.3 years. PCR-detected SARS-CoV-2 infection was diagnosed in all patients. Neutralizing monoclonal antibodies were administered to 69 patients, who formed the study group (group 1). The control group included 33 patients (group 2). The combination of bamlanevimab and etesevimab was the most frequent therapy used (in 59 patients). Results. In the course of the disease, group 1 patients, compared to those of group 2, had statistically significantly higher blood oxygen saturation values (94.2+/-5.7 vs 89.8+/-10.7);they required less frequent oxygen support (29.0 vs 54.5%) and ICU treatment (18.8 vs 48.5%), respectively. Fatal outcomes occurred in 4 (5.8%) of 69 patients who received neutralizing antibodies and in 6 (18.2%) of 33 patients who did not receive the therapy, p<0.05. Except for one patient, all other patients in both groups developed an unfavorable outcome due to progressive lung damage. However, only 4 of 6 (2/3) patients with progressive lung damage died in group 1, whereas the similar course of the disease proved fatal in all cases in group 2. Conclusion. The use of neutralizing monoclonal antibodies in hemodialysis patients is safe and effective when the drugs are administered early, the pulmonary process progression is insignificant and dominant SARSCoV-2 variants are sensitive to them.Copyright © 2022 Tomsk Polytechnic University, Publishing House.

ABSTRACT
Objectives: To evaluate the relationship between depression, anxiety, and stress levels, headaches, and symptoms of temporomandibular joint disorders in healthcare professionals in a post-pandemic setting. Method(s): A cross-sectional study conducted through an online questionnaire was distributed among healthcare professionals in Mainland Portugal. The sample's characterization was undertaken according to sociodemographic parameters. The following assessment instruments were used: 21-item Depression, Anxiety, and Stress Scale (DASS-21) for emotional parameters, namely depression, anxiety, and stress;International Classification of Headache Disorders (ICHD-3) for headache disorders;Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for temporomandibular joint dysfunction symptoms. Inferential analysis was performed using phi, Cramer's V, and gamma tests. Result(s): The sample comprised 118 individuals (93.2% female, 6.8% male). Results showed a prevalence of 38.1% for depression, 51.7% for anxiety, and 39.8% for stress. Regarding headaches, a prevalence of 62.7% was reported. Symptoms of temporomandibular disorders had a prevalence of 50%. Significant differences were found between headache and stress (p=0.034), headache and temporomandibular joint disorders symptoms (p=0.002), and symptoms of temporomandibular disorders and depression (p=0.009), anxiety (p=0.003), and stress levels (p=0.014). Conclusion(s): There seems to be a positive correlation between headaches and stress levels, between temporomandibular disorders symptoms and all psychosocial parameters, and between temporomandibular disorder symptoms and headaches. Data suggests that these symptoms worsened after the pandemic.Copyright © 2023 Sociedade Portuguesa de Estomatologia e Medicina Dentaria. Published by SPEMD.
ABSTRACT
Purpose of Study: The regional NICU is an essential healthcare resource for families of newborns with serious life-threatening illnesses. Mechanical ventilation, cardiovascular therapies, therapeutic hypothermia, and neonatal surgeries are common life-sustaining interventions. Our NICU serves an underprivileged population in a resource poor environment and several ethical questions frequently emerge when facing extremes of innovative therapies. The pandemic and rapidly changing institutional protocols accentuated challenges faced by frontline NICU teams caring for newborns at risk for devastating illnesses and death. Concurrently, evolving paradigms in neonatal ethics required urgent and high quality palliative care in a background of racial and socioeconomic inequities, restrictive visitation policies, and limited healthcare resources. The purpose of this study was to ensure that neonates and their families receive ethically sound care, timely referrals for innovative therapies, and specialized palliative care in the strained and uncertain environment of the COVID-19 pandemic. Methods Used: The key steps consisted of structured and impromptu discussion forums for specialized palliative care and medical ethics, perinatal case conferences and pediatrics grand rounds on virtual platforms, educational webinars for interdisciplinary teams, and improved electronic communication. Online collaboration and innovative combinations of in-person and virtual meetings were utilized for urgently Incorporating clinical updates. Summary of Results: 1. A neonate with severe HIE and postnatally diagnosed congenital diaphragmatic hernia required emergent ECMO center referral. NICU providers utilized a structured bioethics and palliative care framework for providing family support and discussing the prognostication challenges of acute illnesses. 2. Many important bioethical questions emerged while caring for infants with life-threatening chromosomal abnormalities. Ethical tension was addressed by teaching tools, quality of life and pediatrics ethics conversations, mitigation of moral distress, contemporary clinical and surgical experience, community engagement, and family perspectives. 3. Ethical conflicts are central in the decision to resuscitate neonates born between 22 and 23 weeks of gestation. To provide urgent prenatal consultations and attend high risk deliveries, we collaborated across geographically distant healthcare systems, unified management strategies and analyzed outcomes data. 4. NEC in several extremely preterm babies had devastating outcomes and the team respected each family's voice with compassionate, shared decision-making for both curative care surgeries and palliative care. Conclusion(s): The new workflows, telephone and video conferences, and redirection to telehealth based family meetings did not change important outcomes during the pandemic. Advocacy and education for integrating bioethics and palliative care were vital facets of neonatal critical care in a resource poor and ever-changing pandemic environment.
ABSTRACT
Mammals, bacteria, and archaea have domesticated transposases (e.g., RAG1 and Cas1) to form adaptive immune systems. Bacteria and archaea acquire resistance to viruses and plasmids by preferentially integrating fragments of foreign DNA at one end of a CRISPR locus. DNA motifs upstream of the CRISPR (i.e., leader) facilitate integration at the first CRISPR repeat. But how do these upstream DNA motifs act over large distances of 130 bp, or roughly 440 A, to regulate integration allosterically? Here, we determine the structure of a 560 KDa integration complex that explains how the CRISPR leader DNA recruits Cas (i.e., Cas1-2/3) and non-Cas proteins (i.e., IHF). Cas1-2/3 and IHF cooperate to fold the genome into a successive U-shaped bend and a loop. The genomic U-bend traps foreign DNA against the integrase, whereas the genomic loop positions the leader-repeat junction at the Cas1 active site. The foreign DNA and the CRISPR repeat wrap around opposite faces of Cas2, poised for a Cas1-catalyzed strand-transfer reaction. The post-integration structure suggests that strand-transfer releases tension in the DNA loop. Therefore Cas1-2/3 may harness protein-induced DNA tension to favor the completion of the isoenergetic integration reaction. Cas1-2/3 interacts extensively with the leader and repeat without making sequence-specific contacts, and we demonstrate that protein-mediated folding of DNA drives integration into diverse sequences. These results reveal Cas1-2/3 and IHF strain DNA to enhance integration allosterically and suggest a mechanism for the de novo generation of new CRISPRs. Further, to address an urgent need for inexpensive and rapid detection of viruses, we recently repurposed a CRISPR immune signaling pathway to detect SARS-CoV-2 in patient samples.
