Understanding the effects of COVID-19 on patients with diabetic nephropathy: a systematic review.

Background: Diabetic nephropathy is one of the consequences of diabetes mellitus that causes a continuous decline in the eGFR. After the COVID-19 pandemic, studies have shown that patients with diabetic nephropathy who had contracted COVID-19 have higher rates of morbidity and disease progression. The aim of this study was to systematically review the literature to determine and understand the effects and complications of SARS-CoV-2 on patients with diabetic nephropathy. Materials and methods: The authors' research protocol encompassed the study selection process, search strategy, inclusion/exclusion criteria, and a data extraction plan. A systematic review was conducted by a team of five reviewers, with an additional reviewer assigned to address any discrepancies. To ensure comprehensive coverage, the authors employed multiple search engines including PubMed, ResearchGate, ScienceDirect, SDL, Ovid, and Google Scholar. Results: A total of 14 articles meeting the inclusion criteria revealed that COVID-19 directly affects the kidneys by utilizing ACE2 receptors for cell entry, which is significant because ACE2 receptors are widely expressed in the kidney. Conclusion: COVID-19 affects kidney health, especially in individuals with diabetic nephropathy. The mechanisms include direct viral infection and immune-mediated injury. Early recognition and management are vital for improving the outcomes.

High SARS-CoV-2 infection rate in children unvaccinated with COVID-19 vaccine in Changzhou, China, shortly after lifting zero-COVID-19 policy in December 2022.

BACKGROUND: China experienced an overwhelming COVID-19 pandemic from middle December 2022 to middle January 2023 after lifting the zero-COVID-19 policy on December 7, 2022. However, the infection rate was less studied. We aimed to investigate the SARS-CoV-2 infection rate in children shortly after discontinuation of the zero-COVID-19 policy. METHODS: From February 20 to April 10, 2023, we included 393 children aged 8 months to less than 3 years who did not receive COVID-19 vaccination and 114 children aged 3 to 6 years who received inactivated COVID-19 vaccines based on the convenience sampling in this cross-sectional study. IgG and IgM antibodies against nucleocapsid (N) and subunit 1 of spike (S1) of SARS-CoV-2 (anti-N/S1) were measured with commercial kits (Shenzhen YHLO Biotech, China). RESULTS: Of the 393 unvaccinated children (1.5 ± 0.6 years; 52.2% boys), 369 (93.9%) were anti-N/S1 IgG positive. Of the 114 vaccinated children (5.3 ± 0.9 years; 48.2% boys), 112 (98.2%) were anti-N/S1 IgG positive. None of the unvaccinated or vaccinated children was anti-N/S1 IgM positive. The median IgG antibody titers in vaccinated children (344.91 AU/mL) were significantly higher than that in unvaccinated children (42.80 AU/mL) (P < 0.0001). The positive rates and titers of anti-N/S1 IgG had no significant difference between boys and girls respectively. CONCLUSION: Vast majority of children were infected with SARS-CoV-2 shortly after ending zero-COVID-19 policy in China. Whether these unvaccinated infected children should receive COVID-19 vaccine merits further investigation.

Tracheostomy before and during COVID-19 pandemic.

BACKGROUND: The aim of the study was to provide insight into the influence of the COVID-19 on the frequency and characteristics of urgent and emergent tracheostomies (TS), comparing data collected both before and during the pandemic. Our two hypotheses were that during COVID-19, more TS were performed in the emergent setting and that during COVID-19 more TS were performed under general anaesthesia. PATIENTS AND METHODS: The research was retrospective. The study period included the two years before and after the COVID-19 outbreak in Slovenia. Forty-one patients in each period met the inclusion criteria. Their medical charts were reviewed. The anamnestic, clinical, surgical and anaesthesiological data were collected. The two groups of patients from corresponding time periods were statistically compared. RESULTS: Predominantly men required the surgical resolution of acute upper airway obstruction (76% of patients). The causes for acute respiratory distress included head and neck cancer (62%), infections (20%), vocal cord paralysis (16%), and stenosis (2%). There were no statistically significant differences either in the (emergent/urgent) setting of TS or in the type of anaesthesia used. Both hypotheses were rejected. A statistically significant rise in use of the C-MAC laryngoscope during COVID-19 (from 3% to 15%) was reported. CONCLUSIONS: The outbreak of COVID-19 did not have a statistically significant effect on the frequency of performing emergent and urgent tracheostomies nor on the use of general or local anaesthesia. It did, however, require a change of intubation technique. Consequently, a significant rise in the use of the C-MAC laryngoscope was noted.

Covid-19 in Parkinson's Disease treated by drugs or brain stimulation / COVID-19 en la enfermedad de Parkinson tratada con fármacos o estimulación cerebral

Purpose: Covid-19 has affected all people, especially those with chronic diseases, including Parkinson's Disease (PD). Covid-19 may affect both motor and neuropsychiatric symptoms of PD patients. We intend to evaluate different aspects of Covid-19 impact on PD patients. Methods: 647 PD patients were evaluated in terms of PD-related and Covid-19-related clinical presentations in addition to past medical history during the pandemic through an online questioner. They were compared with an age-matched control group consist of 673 individuals and a sample of the normal population consist of 1215 individuals. Results: The prevalence of Covid-19 in PD patients was 11.28%. The mortality was 1.23% among PD patients. The prevalence of Covid-19 in PD patients who undergone Deep Brain Stimulation (DBS) was 18.18%. No significant association was found between the duration of disease and the prevalence of Covid-19. A statistically significant higher prevalence of Covid-19 in PD patients who had direct contact with SARS-CoV-19 infected individuals was found. No statistically significant association has been found between the worsening of motor symptoms and Covid-19. PD patients and the normal population may differ in the prevalence of some psychological disorders, including anxiety and sleeping disorders, and Covid-19 may affect the psychological status. Conclusion: PD patients possibly follow tighter preventive protocols, which lead to lower prevalence and severity of Covid-19 and its consequences in these patients. Although it seems Covid-19 does not affect motor and psychological aspects of PD as much as it was expected, more accurate evaluations are suggested in order to clarify such effects.(AU)

Objetivo: La COVID-19 ha afectado a toda la población, especialmente a aquellos con enfermedades crónicas, incluyendo a los pacientes con enfermedad de Parkinson (EP). La COVID-19 puede empeorar tanto los signos motores como los síntomas neuropsiquiátricos de los pacientes con EP. El objetivo de este estudio es evaluar diferentes aspectos del impacto de la COVID-19 en los pacientes con EP. Métodos: A través de un cuestionario virtual se evaluó a 647 pacientes con EP de acuerdo con sus presentaciones clínicas relacionadas con la EP y con la COVID-19, además de la historia médica previa durante la pandemia. Se compararon con un grupo de controles sanos de la misma edad que constaba de 673 individuos y una muestra de la población general de 1.215 individuos. Resultados: La prevalencia de la COVID-19 en pacientes con EP fue del 11,28%. La mortalidad fue del 1,23% entre los pacientes con EP. La prevalencia de COVID-19 en pacientes con EP con estimulación cerebral profunda fue del 18,18%. No se encontró una asociación significativa entre la duración de la enfermedad y la prevalencia de COVID-19. Se halló una prevalencia mayor de COVID-19 que fue estadísticamente significativa en pacientes con EP que tuvieron contacto directo con personas infectadas con SARS-CoV-2. No se encontró una asociación estadísticamente significativa entre el empeoramiento de los signos motores y la COVID-19. Los pacientes con EP y la población general podrían diferir en la prevalencia de algunos trastornos psicológicos, incluidos los trastornos de ansiedad y del sueño, y la COVID-19 podría afectar al estado psicológico. Conclusión: Los pacientes con EP posiblemente sigan protocolos preventivos más estrictos, lo que conduce a una menor prevalencia y gravedad de COVID-19 y de sus consecuencias en estos pacientes.(AU)

"Who Takes Care of Carers?": Experiences of Intensive Care Unit Nurses in the Acute Phase of the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic caused an international health emergency situation where nursing took on a fundamental role. The high number of patients in hospital ICUs led to a shift in nurses' working conditions and workload. Objective: The objective of this study was to describe the experiences of nurses who worked in ICUs during the acute phase of the COVID-19 pandemic. Methodology: A qualitative, descriptive study was carried out, with the participation of 21 nurses who worked in the ICU during the pandemic. Data collection took place between May and July 2021 through 21 in-depth interviews. Results: Three main themes emerged: (1) COVID-19 in ICUs: nurses on the frontline. (2) United against adversity: teamwork. (3) New optics of critical care and the nursing profession. COVID-19 was perceived with harshness, and the lack of knowledge about the virus generated confusion, anxiety and fear due to the risk of transmission to family members and relatives. The pandemic marked a shift in the management of human, material and economic resources. Novice nurses learned critical care at an accelerated pace, with significant physical and psychological strain. Expert nurses carried the burden of training new nurses. Although there were tense situations, experiencing these adverse situations as a team led to feelings of increased belonging, togetherness and professional bonding for nurses. While the participants noted an increase in motivation to continue in their profession, they also had a feeling of not having been cared for as they deserve by healthcare institutions.

Antiviral and antibacterial properties of phloroglucinols: a review on naturally occurring and (semi)synthetic derivatives with potential therapeutic interest.

Phloroglucinol and derived compounds comprise a huge class of secondary metabolites widely distributed in plants and brown algae. A vast array of biological activities, including antioxidant, anti-inflammatory, antimicrobial, and anticancer has been associated to this class of compounds. In this review, the available data on the antiviral and antibacterial capacity of phloroglucinols have been analyzed. Some of these compounds and derivatives show important antimicrobial properties in vitro. Phloroglucinols have been shown to be effective against viruses, such as human immunodeficiency virus (HIV), herpes or enterovirus, and preliminary data through docking analysis suggest that they can be effective against SARS-CoV-19. Also, some phloroglucinols derivatives have shown antibacterial effects against diverse bacteria strains, including Bacillus subtilis and Staphylococcus aureus, and (semi)synthetic development of novel compounds have led to phloroglucinols with a significantly increased biological activity. However, therapeutic use of these compounds is hindered by the absence of in vivo studies and scarcity of information on their mechanisms of action, and hence further research efforts are required. On the basis of this consideration, our work aims to gather data regarding the efficacy of natural-occurring and synthetic phloroglucinol derivatives as antiviral and antibacterial agents against human pathogens, which have been published during the last three decades. The recollection of results reported in this review represents a valuable source of updated information that will potentially help researchers in the development of novel antimicrobial agents.

Management of post-mortem examination in SARS-CoV-19 infections.

A brief overview on the management of autopsies during the SARS-CoV-19 epidemic is proposed. In particular, the point is made of the Italian laws on the subject, the characteristics required for the autopsy room and the sampling suggested for the histological examination.

Incidence of SARS-CoV-2 infection in children shortly after ending zero-COVID-19 policy in China on December 7, 2022: a cross-sectional, multicenter, seroepidemiological study.

Background: China discontinued the zero-COVID-19 policy on December 7, 2022, and then COVID-19 surged mid-December 2022 through mid-January 2023. However, the actual incidence was unknown. This study aimed to estimate the incidence of SARS-CoV-2 infection in children shortly after ending the zero-COVID-19 policy. Methods: This multicenter cross-sectional study included 1,065 children aged 8 months to 12 years from seven hospitals at six regions across Jiangsu province, based on the convenience sampling, from February 10 to March 10, 2023. Group I comprised 324 children aged 8 months-2 years without COVID-19 vaccination, group II consisted of 338 preschool children aged 3-5 years with varied vaccination history, and group III contained 403 primary school children aged 6-12 years with mostly vaccinated. The COVID-19 vaccines were composed of inactivated SARS-CoV-2. In addition, 96 children's sera collected in 2014 were included as negative controls. IgG and IgM antibodies against nucleocapsid (N) and subunit 1 of spike (S1) of SARS-CoV-2 (anti-N/S1) were measured with commercial kits (YHLO Biotech, Shenzhen, China). Results: None of the 96 children (5.1 ± 3.5 years; 58.3% boys) in 2014 was positive for anti-N/S1 IgG or IgM. Of the 1,065 children (5.0 ± 3.5 years; 56.0% boys), 988 (92.8%) were anti-N/S1 IgG positive but none was anti-N/S1 IgM positive. The positive rate of anti-N/S1 IgG in Group I, II, and III was 90.4, 88.5, and 98.3%, respectively, with significantly higher in group III than in groups I and II (p < 0.0001). The median antibody titers in group III (381.61 AU/ml) were much higher than that in group I (38.34 AU/ml) and II (51.88 AU/ml; p < 0.0001). Conclusion: More than 90% children experienced SARS-CoV-2 infection shortly after ending zero-COVID-19 policy in China, much higher than estimated infections by other studies. The widespread SARS-CoV-2 infection in unvaccinated children should be influential on the policy of COVID-19 vaccination in children in the future.

Goldilocks Energy Minimum: Peptide-Based Reversible Aggregation and Biosensing.

Colorimetric biosensors based on gold nanoparticle (AuNP) aggregation are often challenged by matrix interference in biofluids, poor specificity, and limited utility with clinical samples. Here, we propose a peptide-driven nanoscale disassembly approach, where AuNP aggregates induced by electrostatic attractions are dissociated in response to proteolytic cleavage. Initially, citrate-coated AuNPs were assembled via a short cationic peptide (RRK) and characterized by experiments and simulations. The dissociation peptides were then used to reversibly dissociate the AuNP aggregates as a function of target protease detection, i.e., main protease (Mpro), a biomarker for severe acute respiratory syndrome coronavirus 2. The dissociation propensity depends on peptide length, hydrophilicity, charge, and ligand architecture. Finally, our dissociation strategy provides a rapid and distinct optical signal through Mpro cleavage with a detection limit of 12.3 nM in saliva. Our dissociation peptide effectively dissociates plasmonic assemblies in diverse matrices including 100% human saliva, urine, plasma, and seawater, as well as other types of plasmonic nanoparticles such as silver. Our peptide-enabled dissociation platform provides a simple, matrix-insensitive, and versatile method for protease sensing.

The impact of COVID-19 pandemic lockdown on smoking habits and lifestyle: A cross-sectional study.

Background and Aims: Throughout the COVID-19 lockdown, the resultant psychological disturbances led to more tobacco consumption and deteriorated smoking behaviors among smokers. In this study, we aimed to investigate the impact of the COVID-19 pandemic on the smoking behaviors of the Jordanian population. Methods: A cross-sectional online survey was designed using the Google Forms service and distributed by social media platforms. Responses were collected starting from November 12, 2020, until November 24, 2020. Results: A total of 2511 respondents completed the survey, 77.3% were females. Males were significantly smoking more than females (p < 0.0001). Smoking was significantly more common among respondents who were older than 18 years old, married, held master's and PhD degrees, and working in non-health-related fields (p < 0.0001). Participants who smoke were more likely to adopt an unhealthy lifestyle during the pandemic. Females who started smoking last year were 2.6-fold more than males (p < 0.0001). We also noticed that there is a significant relationship between those who started smoking and are <18 years, living in a family consisting of seven members or more, being unemployed, having a diploma or bachelor's degree in a health-related major, having no chronic illnesses, increasing of daily meals or night meals, almost daily sugar intake, starting to follow social media account concerning physical activity, exercising once or twice a week, and sleeping more hours per day since the beginning of the pandemic (p < 0.01). Conclusion: The results of our study showed that the lockdown had a significant impact on people's lifestyles including smoking habits. Most of our sample's smoker participants experienced a change in their smoking level mostly, an increase. While those who had a decrease in their smoking level experienced a somehow healthier lifestyle regarding nutrition and other aspects.

Diet quality and associated factors in Brazilian undergraduates during the COVID-19 pandemic.

Background: Diet quality is associated with psychobiological, psychological, biological, and physiological factors of individuals, and in the context of prolonged stress, such as the COVID-19 pandemic, it can lead to a worsening of the quality of food for undergraduates. This study aimed to analyze diet quality and associated factors in Brazilian undergraduates. Methods: Data were collected from 4,799 undergraduate students from all Brazilian regions, from August 2020 to February 2021. The online questionnaire contained socioeconomic variables, the ESQUADA scale to assess diet quality, self-referred changes in weight, the Brazilian food insecurity scale (EBIA), sleep assessment and the perceived stress scale. Unconditional multiple logistic regression analysis was performed to study variables associated with poor and very poor diet quality. Results: Most of participants presented a good diet quality (51.7%), while 9.8% had a poor or very poor diet quality and only 1.1% had an excellent diet quality. 58.2% of undergraduates reported to have an increase in weight during the pandemic and 74.3% of the students presented elevated stress during the pandemic. Logistic regressions showed students who gained weight during the pandemic presented the highest AOR = 1.56 (95% CI = 1.12-2.20) for poor or very poor diet quality. The elevated perceived stress was also associated with a higher AOR = 2.85 (95% CI = 1.71-4.74) for poor or very poor diet quality. Conclusion: Most of the studied undergraduates presented a good diet quality. Nevertheless, poor/very poor diet quality was associated with higher perceived stress and weight gain. Our study indicated that policies should beaimed at the socioeconomically most vulnerable undergraduates, those in a situation of food and nutritional insecurity, high perceived stress, and who gained weight during the pandemic.

Impacto de la pandemia por COVID-19 en los Servicios de Rehabilitación de España / Pandemic COVID-19 impact in Rehabilitation Services in Spain

Introducción: El presente estudio tiene como objetivo describir la adaptación de los servicios de Rehabilitación al rápido y significativo incremento de pacientes con COVID-19 con necesidad de valoración y tratamiento rehabilitador. Material y métodos: Estudio transversal. Se realizó una encuesta online entre los principales servicios de Rehabilitación de España entre el 22-12-2020 y el 27-02-2021. Un comité de expertos de SORECAR desarrolló la encuesta. El análisis se realizó utilizando SPSS v22.0.

Introduction: The COVID-19 pandemic situation has brought a considerable growth on the amount of patients requiring ICU admissions and long-term hospitalization. The present study is aimed at determining whether Rehabilitation Services has been able to reach a sufficient adaptation level, regarding the exponential increase on the demand of Rehab-related services from intensive care patients and inpatients. Material and methods: Through this cross-sectional research, an online survey was implemented in various Rehabilitation Departments across Spain from December the 22nd, 2020 to February the 12th, 2021. SORECAR (The Spanish Cardiopulmonary Rehabilitation Society) was the responsible entity for the design of the survey (ICU Rehabilitation Services Identification). Descriptive statistical analysis was conducted using SPSS. Objective: To address the specific needs and changes arising from the new COVID-19 pandemic situation within Spanish Rehabilitation Departments. Results: 38 hospitals from 18 cities (From a total of 49) participated in the study. The ICUs weekly demand scored 7.84 ± 6,8 Medical Consultation (MC) on average (range: 2-45). The hospitalization average was displayed as 9, 63 ± 6,2 MC/week (range: 2-55). The total worktime dedicated by physicians was 10.38 h/week, from which physiotherapists stood with 25.95 h/week. Only 7 hospitals (16.7%) counted with occupational therapists (OT) (average dedication of 5 h/week). Each Rehab-session lasted 30 min on average.(AU)

Ischemic stroke in the setting of supratherapeutic International Normalized Ratio following coronavirus disease 2019 infection: a case report.

BACKGROUND: SARS-CoV-19 infection is associated with an increased risk of thrombotic events. We present a case of acute middle cerebral artery ischemic stroke in a patient with SARS-CoV-19 infection despite being on warfarin with supratherapeutic INR (International Normalized Ratio). CASE PRESENTATION: A 68-year-old Caucasian female with multiple comorbidities was admitted to the hospital with symptoms of upper respiratory tract infection. A rapid antigen test confirmed the diagnosis of COVID-19 pneumonia, and intravenous remdesivir was initiated. On the fifth day of admission, the patient experienced sudden onset confusion, slurred speech, left-sided hemiplegia, right-sided eye deviation, and left-sided facial droop. Imaging studies revealed an occlusion of the distal anterior M2 segment of the right middle cerebral artery, and an MRI of the brain confirmed an acute right MCA infarction. Notably, the patient was receiving warfarin therapy with a supratherapeutic INR of 3.2. CONCLUSIONS: This case report highlights the potential for thromboembolic events, including stroke, in patients with COVID-19 infection, even when receiving therapeutic anticoagulation therapy. Healthcare providers should be vigilant for signs of thrombosis in COVID-19 patients, particularly those with pre-existing risk factors. Further research is necessary to understand the pathophysiology and optimal management of thrombotic complications in COVID-19 patients.

Psychosocial Factors Associated with Memory Complaints during the First Wave of the COVID-19 Pandemic: A Multi-Country Survey.

This study assessed the associations between psychosocial factors (social isolation, social support, financial support and emotional distress) and memory complaints during the COVID-19 pandemic. This was a secondary analysis of data extracted from the dataset of participants recruited from 151 countries for a COVID-19 related mental health and wellness study between June and December 2020. The dependent variable was memory complaint, measured using the Memory Complaint Questionnaire. The independent variables were perception of social isolation, social support, financial support, emotional distress and history of SARS-CoV-19 infection. Confounding variables were age, sex at birth, level of education, employment status, HIV status and country-income level. Multivariable logistic regression was used to determine the associations between the dependent and independent variables after adjusting for the confounders. Of the 14825 participants whose data was extracted, 2460 (16.6%) had memory complaints. Participants who felt socially isolated (AOR: 1.422; 95% CI: 1.286-1.571), emotionally distressed (AOR: 2.042; 95% CI: 1.850-2.253) and with history of SARS-CoV-19 infection (AOR: 1.369; 95% CI: 1.139-1.646) had significantly higher odds of memory complaints. Participants who perceived they had social and financial support had significantly lower odds of memory complaints (AOR: 0.655; 95% CI: 0.571-0.751). Future management of pandemics like the COVID-19 should promote access to social and financial support and reduce the risk of social isolation and emotional distress.

The Use of Rapid COVID-19 Antigen Test in the Emergency Department as a Decision-Support Tool.

The emergency department (ED) is the initial point of contact between hospital staff and patients potentially infected with SARS-CoV-2, thus, prevention of inadvertent exposure to other patients is a top priority. We aimed to assess whether the introduction of antigen-detecting rapid diagnostic tests (Ag-RDTs) to the ED affected the likelihood of unwanted SARS-CoV-2 exposures. In this retrospective single-center study, we compared the rate of unwarranted exposure of uninfected adult ED patients to SARS-CoV-2 during two separate research periods; one before Ag-RDTs were introduced, and one with Ag-RDT used as a decision-support tool. The introduction of Ag-RDTs to the ED significantly decreased the relative risk of SARS-CoV-2-negative patients being incorrectly assigned to the COVID-19 designated site ("red ED"), by 97%. There was no increase in the risk of SARS-CoV-2-positive patients incorrectly assigned to the COVID-19-free site ("green ED"). In addition, duration of ED admission was reduced in both the red and the green ED. Therefore, implementing the Ag-RDT-based triage protocol proved beneficial in preventing potential COVID-19 nosocomial transmission.

Comparison of the efficacy of equivalent doses of dexamethasone, methylprednisolone, and hydrocortisone for treatment of COVID-19-related acute respiratory distress syndrome: a prospective three-arm randomized clinical trial.

BACKGROUND: This prospective controlled clinical trial aimed to compare the efficacy of methylprednisolone, dexamethasone, and hydrocortisone at equivalent doses in patients with severe COVID-19. METHODS: In total, 106 patients with mild to moderate COVID-19-related acute respiratory distress syndrome (ARDS) were randomized to receive either dexamethasone (6 mg once a day), methylprednisolone (16 mg twice a day), or hydrocortisone (50 mg thrice a day) for up to 10 days. All participants received a standard of care for COVID-19. The primary and secondary efficacy outcomes included all-cause 28-day mortality, clinical status on day 28 assessed using the World Health Organization (WHO) eight-category ordinal clinical scale, number of patients requiring mechanical ventilation and intensive care unit (ICU) care, number of ventilator-free days, length of hospital and ICU stay, change in PaO2:FiO2 ratios during the first 5 days after treatment, and incidence of serious adverse events. P-values below 0.008 based on Bonferroni's multiple-testing correction method were considered statistically significant. RESULTS: According to the obtained results, there was a trend toward more favorable clinical outcomes in terms of needing mechanical ventilation and ICU care, number of ventilator-free days, change in PaO2:FiO2 ratios during the first 5 days after treatment, clinical status score at day 28, length of ICU and hospital stay, and overall 28-day mortality in patients receiving dexamethasone compared to those receiving methylprednisolone or hydrocortisone; however, likely due to the study's small sample size, the difference between groups reached a significant level only in the case of clinical status score on day 28 (p-value = 0.003). There was no significant difference in the incidence of serious adverse events between the study groups. CONCLUSION: Based on the results, severe cases of COVID-19 treated with dexamethasone might have a better clinical status at 28-day follow-up compared to methylprednisolone and hydrocortisone at an equivalent dose. Larger multicenter trials are required to confirm our findings.

Descriptive statistical analysis was conducted using SPSS. OBJECTIVE: To address the specific needs and changes arising from the new COVID-19 pandemic situation within Spanish Rehabilitation Departments. RESULTS: 38 hospitals from 18 cities (From a total of 49) participated in the study. The ICUs weekly demand scored 7.84 ± 6,8 Medical Consultation (MC) on average (range: 2-45). The hospitalization average was displayed as 9, 63 ± 6,2 MC/week (range: 2-55). The total worktime dedicated by physicians was 10.38 h/week, from which physiotherapists stood with 25.95 h/week. Only 7 hospitals (16.7%) counted with occupational therapists (OT) (average dedication of 5 h/week). Each Rehab-session lasted 30 min on average. 59.1% (n = 23) of the included hospitals had already implemented a specific post-covid follow-up rehab-consultation, whereas 9.1% (n = 4) of them were planning on implementing it. 64.3% (n = 24) of the surveyed centers implemented specific protocols for COVID-19 patients, while another 7.1% (n = 3) were in development progress. 48.5% (n = 18) of the surveyed centers did not owe its own specific training program within its ICUs and respiratory rehab-areas for the internal medical residents. CONCLUSIONS: The pandemic situation has resulted in a substantial increase on the workload in the Spanish Rehabilitation Services. Most of the hospitals included in the present study had already implemented outpatient follow-up consultations. Rehabilitation in critical patients is an exponentially recurrent topic for this medical specialty that needs to be furtherly addressed in the nearby future.

Efficacy Of PanbioTM Covid-19 Ag Rapid Test In Sars-Cov-2 Detection: Comparison With RT-PCR Test.

Background: Evidence on performance of Rapid Antigen Detection Tests to recognize SARS-CoV-2 symptomatic patients in our context is limited. This study was aimed to evaluate Panbio™ COVID-19 Ag Rapid Test Device (Abbott Diagnostics, Jena, Germany) in identifying SARS-CoV-2 infection in comparison with RT-PCR test. Methods: This cross-sectional validation study was carried out at Margalla Hospital, Taxila from October, 2020 to March, 2021. Three hundred and eighty-two participants of both gender and all ages, symptomatic for 3-4 days were included in this study. For each participant, two nasopharyngeal swabs were collected by trained lab technicians according to SOPs, one for Rapid Antigen Test and other for RT-PCR.Covid-19 antibodies were checked 4-6 weeks after symptoms among 77 randomly selected participants to further evaluate the performance of Rapid Antigen Test. Data was analyzed using SPSS-26. Results: The mean age of the participants was 43.1 years (SD=15.9). More than half of participants were males (n=213%=55.8) and 169 (44.2%) were females. Sensitivity of Rapid Antigen Test was calculated to be 94.3%, whereas the specificity was 39.7%. Out of 34 RT-PCR negatives that were initially detected positive on Rapid Antigen Test, 33 demonstrated presence of COVID-19 antibodies. Conclusion: Panbio™ COVID-19 Ag Rapid Test was found to have 93.4% overall sensitivity and relatively low overall specificity (37.9%). Rapid antigen testing using Panbio™ COVID-19 Ag Rapid Test Device can be effectively used to scale up mass testing to interrupt transmissibility of COVID-19 infection by generating quick result.

Using digital chatbots to close gaps in healthcare access during the COVID-19 pandemic.

INTRODUCTION: Chatbots have emerged as a first link to care in recent years. The COVID-19 pandemic, and consequent health system disruptions, expanded their use. Socios En Salud (SES) introduced chatbots in Peru, which experienced one of the highest excess COVID mortalities in the world. METHODS: SES and the government identified unmet population health needs, which could be amenable to virtual interventions. Chatbots were developed to screen individuals for these conditions; we describe the period of deployment, number of screenings, and number of people who received services. RESULTS: Between April 2020 and May 2021, SES deployed nine ChatBots: four for mental health, two for maternal and child health, and three for chronic diseases: breast cancer, hypertension, diabetes mellitus, and obesity. Mental health services were provided to 42,932 people, 99.99% of those offered services. The other ChatBots reached fewer people. Overall, more than 50% of eligible people accepted chatbot-based services. DISCUSSION: ChatBot use was highest for mental health. Chatbots may increase connections between a vulnerable population and health services; this is likely dependent on several factors, including condition, population, and penetration of smart phones. Future research will be critical to understand user experience and preferences and to ensure that chatbots link vulnerable populations to appropriate, high-quality care.

INTRODUCTION: Les chatbots se sont imposés comme un premier lien aux soins ces dernières années. La pandémie de COVID-19, et les perturbations du système de santé qui en ont résultées, ont élargi leur champ d'application. Socios En Salud (SES) a introduit les chatbots au Pérou, qui a connu l'une des surmortalités dues au COVID les plus élevées au monde. MÉTHODES: SES et le gouvernement ont identifié des besoins non satisfaits en matière de santé de la population, qui pourraient faire l'objet d'interventions virtuelles. Des chatbots ont été développés pour dépister des individus pour ces conditions ; nous décrivons la période de leur déploiement, le nombre de dépistages et le nombre de personnes qui ont reçu ces services. RÉSULTATS: Entre avril 2020 et mai 2021, SES a déployé neuf ChatBots : quatre pour la santé mentale, deux pour la santé maternelle et infantile et trois pour les maladies chroniques, comme le cancer du sein, l'hypertension, le diabète et l'obésité. Des services de santé mentale ont été fournis à 42 932 personnes, soit 99,99% des personnes proposées. Les autres ChatBots ont touché moins de personnes. Dans l'ensemble, plus de 50% des personnes éligibles ont accepté les services proposés par les chatbots. DISCUSSION: L'utilisation des ChatBots était la plus élevée pour la santé mentale. Les chatbots peuvent augmenter les connexions entre une population vulnérable et les services de santé, mais cela dépende de plusieurs facteurs, dont la condition, la type de population et la pénétration des smartphones. Les recherches futures seront essentielles pour comprendre l'expérience et les préférences des utilisateurs et pour s'assurer que les chatbots relient les populations vulnérables vulnérables aux soins appropriés et de qualité.
