Acute colonic pseudo-obstruction syndrome in patients with severe COVID-19 in Buenos Aires, Argentina.

BACKGROUND: Several gastrointestinal complications have been reported in patients with COVID-19, including motility disorders, such as acute colonic pseudo-obstruction (ACPO). This affection is characterized by colonic distention in the absence of mechanical obstruction. ACPO in the context of severe COVID-19 may be related to neurotropism and direct damage of SARS-CoV-2 in enterocytes. METHOD: We conducted a retrospective study of patients who were hospitalized for critical COVID-19 and developed ACPO between March 2020 and September 2021. The diagnostic criteria to define ACPO was the presence of 2 or more of the following: abdominal distension, abdominal pain, and changes in the bowel movements, associated with distension of the colon in computed tomography. Data of sex, age, past medical history, treatment, and outcomes were collected. RESULTS: Five patients were detected. All required admission to the Intensive Care Unit. The ACPO syndrome developed with a mean of 33.8 days from the onset of symptoms. The mean duration of the ACPO syndrome was 24.6 days. The treatment included colonic decompression with placement of rectal and nasogastric tubes, endoscopy decompression in two patients, bowel rest, fluid, and electrolytes replacement. One patient died. The remaining resolved the gastrointestinal symptoms without surgery. CONCLUSIONS: ACPO is an infrequent complication in patients with COVID-19. It occurs especially in patients with critical condition, who require prolonged stays in intensive care and multiple pharmacological treatments. It is important to recognize its presence early and thus establish an appropriate treatment, since the risk of complications is high.

The evolution of loan volume and non-performing loans under COVID-19 innovations: The Colombian case.

Financial institutions' scale of total and non-performing loans are important figures signaling economic activity and its risk level. COVID-19 created an external shock with overarching effects on the global economy, impacting the credit activity and debtors' ability to repay their obligations. We study how Colombia's loans and non-performing loans market ratios could react to an external shock (absent of any relief measures) by developing a vector autoregressive model with exogenous variables (VARX) with the Central Bank intervention rate as an exogenous variable. We use impulse response functions to simulate the impact of the COVID-19 pandemic on the market of loans and default levels in Colombia. Our results show that the effects remain significant over long periods.

Coping with global uncertainty: Perceptions of COVID-19 psychological distress, relationship quality, and dyadic coping for romantic partners across 27 countries

[Correction Notice: An Erratum for this article was reported in Vol 39(1) of Journal of Social and Personal Relationships (see record 2022-18336-005). Three new authors (Adnan Adil, Emmanuel Asampong, and Rahmattullah Khan Abdul Wahab Khan) were not initially listed in the Epub ahead of print. Table 1 also contained some errors. The corrections are given in the erratum.] Following the global outbreak of COVID-19 in March 2020, individuals report psychological distress associated with the "new normal"-social distancing, financial hardships, and increased responsibilities while working from home. Given the interpersonal nature of stress and coping responses between romantic partners, based on the systemic transactional model this study posits that perceived partner dyadic coping may be an important moderator between experiences of COVID-19 psychological distress and relationship quality. To examine these associations, self-report data from 14,020 people across 27 countries were collected during the early phases of the COVID-19 pandemic (March-July, 2020). It was hypothesized that higher symptoms of psychological distress would be reported post-COVID-19 compared to pre-COVID-19 restrictions (Hypothesis 1), reports of post-COVID-19 psychological distress would be negatively associated with relationship quality (Hypothesis 2), and perceived partner DC would moderate these associations (Hypothesis 3). While hypotheses were generally supported, results also showed interesting between-country variability. Limitations and future directions are presented.

Hospital admission and vaccination as predictive factors of long COVID-19 symptoms.

Background: Since the beginning of the COVID-19 pandemic, a great variability of symptoms that affect all organs and systems of the body has been identified in patients with SARS-CoV-2 infection; this symptomatology can sometimes persist over time, giving rise to the so-called long COVID or post-COVID. The aim of this study is to delve into the clinical characterization of these patients, as well as to take into account the influence of factors such as hospitalization, admission to ICU, history of pneumonia, or vaccination status on the persistence of symptoms. Material and methods: An observational, descriptive, multicenter, and retrospective study was designed with a series of cases of people who presented long COVID, which includes univariate, bivariate, and multivariate analyses. Data were obtained from an online ad hoc questionnaire, and statistical analysis was performed using SPSS Software Version 25 (IBM-Inc., Chicago, IL, USA). Results: Hospitalization, ICU admission, history of pneumonia, and vaccination were predictive factors (positive or negative) for the following long-COVID symptoms: headache, menstrual disorders, joint pain, cough, chills, nasal congestion, back pain, abdominal pain, weight loss, eye discomfort, facial erythema, itching, tremors, dizziness, seizures, sleeping difficulty, dry eyes, palpitations, fatigue, paresthesia, dyspnea, aphonia, chest pain, high blood pressure, vomiting, memory loss, brain fog, hypothermia, low blood pressure, sputum or phlegm, lack of concentration, hair loss, and erectile dysfunction. Conclusion: This study provides evidence on the clinical characterization of patients suffering from long COVID in order to offer them the most appropriate treatments.

Long COVID Symptomatology and Associated Factors in Primary Care Patients: The EPICOVID-AP21 Study.

Persistent COVID-19 condition includes a wide variety of symptoms and health problems of indeterminate duration. The present study examined the sociodemographic and clinical characteristics of the population with Long COVID seen in Primary Care using a questionnaire based on the existing scientific literature. It was an observational and descriptive study of the characteristics of the Spanish population with Long COVID over 14 years of age. The responses were analysed by means of a descriptive analysis of the variables recorded, in addition to a bivariate analysis to determine the existence of a relationship between persistent COVID-19 and variables such as gender, age, vaccination status or concomitant pathology. The results obtained clearly describe the sociodemographic characteristics of the population, highlighting the predominance of female gender and the prevalence of tiredness and fatigue. Furthermore, relevant information was obtained on the differences in symptomatology according to gender, age, previous pathologies and alterations derived from infection and/or vaccination. These data are important for better detection, diagnosis and treatment of Long COVID and the improvement of the quality of life of this population.

The environmental pollution caused by cemeteries and cremations: A review.

In recent years the funeral industry has drawn attention from the scientific community concerning the potential pollution of the environment and the urban environment. In this review, the pollution caused by the cemeteries and crematoria around the world was addressed. The traditional burial leads to the production of ions, in the form of organic and heavy metals, bacteria, fungi, and viruses, that spread along with the soil and underwater. The crematoria produce small particles, trace gases (SOx, NOx, CO), and toxic organic volatiles. The effluent generated by both methods can lead to several environmental problems and further threaten human health. The current solution for the cemeteries in the development of a system in which effluent generated by the traditional burials are collected and treated before realizing in the environment. In addition to that, the green burial should be an alternative, since the corpse does not go through the embalming process, thus eliminating the presence of any undesired chemicals, that are further leached onto the environment. The crematoria should be employed as it is, however, the gas treatment station should be employed, to ensure the minimization of the impact on the environment. Last, future researches regarding the treatment of the cemeteries leached still need to be explored as well as the optimization and further development of the crematoria gas treatment process.

Associations of Dynapenic Obesity and Sarcopenic Obesity with the Risk of Complications in COVID-19.

Ageing is associated with changes in body composition, such as low muscle mass (sarcopenia), decreased grip strength or physical function (dynapenia), and accumulation of fat mass. When the accumulation of fat mass synergistically accompanies low muscle mass or reduced grip strength, it results in sarcopenic obesity and dynapenic obesity, respectively. These types of obesity contribute to the increased risk of cardiovascular disease and mortality in the elderly, which could increase the damage caused by COVID-19. In this review, we associated factors that could generate a higher risk of COVID-19 complications in dynapenic obesity and sarcopenic obesity. For example, skeletal muscle regulates the expression of inflammatory cytokines and supports metabolic stress in pulmonary disease; hence, the presence of dynapenic obesity or sarcopenic obesity could be related to a poor prognosis in COVID-19 patients.

Nanobodies Protecting From Lethal SARS-CoV-2 Infection Target Receptor Binding Epitopes Preserved in Virus Variants Other Than Omicron.

The emergence of SARS-CoV-2 variants that escape from immune neutralization are challenging vaccines and antibodies developed to stop the COVID-19 pandemic. Thus, it is important to establish therapeutics directed toward multiple or specific SARS-CoV-2 variants. The envelope spike (S) glycoprotein of SARS-CoV-2 is the key target of neutralizing antibodies (Abs). We selected a panel of nine nanobodies (Nbs) from dromedary camels immunized with the receptor-binding domain (RBD) of the S, and engineered Nb fusions as humanized heavy chain Abs (hcAbs). Nbs and derived hcAbs bound with subnanomolar or picomolar affinities to the S and its RBD, and S-binding cross-competition clustered them in two different groups. Most of the hcAbs hindered RBD binding to its human ACE2 (hACE2) receptor, blocked cell entry of viruses pseudotyped with the S protein and neutralized SARS-CoV-2 infection in cell cultures. Four potent neutralizing hcAbs prevented the progression to lethal SARS-CoV-2 infection in hACE2-transgenic mice, demonstrating their therapeutic potential. Cryo-electron microscopy identified Nb binding epitopes in and out the receptor binding motif (RBM), and showed different ways to prevent virus binding to its cell entry receptor. The Nb binding modes were consistent with its recognition of SARS-CoV-2 RBD variants; mono and bispecific hcAbs efficiently bound all variants of concern except omicron, which emphasized the immune escape capacity of this latest variant.

Susana Distancia: memes and popular culture during the COVID-19 pandemic

Between the end of March and June 2020, COVID-19 quickly spread in Mexico. As a response, the Mexican government announced its national prevention campaign, called ‘Susana Distancia,’ a set of measures, recommendations, conferences, educational resources, and a chatbot. At the centre of the campaign was Susana Distancia’s character, a young woman designed in a comic-book-style, echoing the Mexican lucha libre heroes, who recommended keeping 1.5 m (6 feet) of physical distance to prevent contagion. In the following visual essay, we analyse Susana Distancia’s role, from its institutional origins to its later transformation as a popular culture meme. Based on the Latin American theory of the popular, we argue that the Susana Distancia, as a meme, used various mechanisms to support and challenge the institutional discourse. In this sense, Susana Distancia can be considered a meme that embraces the popular: a cultural artefact that travels across different languages, spaces, and rituals, from cyberspace to the streets, from governmental intentions to everyday performativity. When we use lo popular as a category, we refer to the possibility of enacting subaltern narratives in aesthetic and ethical terms. Multiple readings and manifestations of Susana Distancia demonstrate popular culture as a means of travelling through diverse semantic appropriations. Various forms of popular culture: the politised, the artistic, the erotic, the authentic, the mainstream, and the political, converge in the translation of meaning, from the institutional discourse to the lived experiences of the Mexican population.

Nanostructures for drug delivery in respiratory diseases therapeutics: Revision of current trends and its comparative analysis.

Respiratory diseases are leading causes of death and disability in developing and developed countries. The burden of acute and chronic respiratory diseases has been rising throughout the world and represents a major problem in the public health system. Acute respiratory diseases include pneumonia, influenza, SARS-CoV-2 and MERS viral infections; while chronic obstructive pulmonary disease (COPD), asthma and, occupational lung diseases (asbestosis, pneumoconiosis) and other parenchymal lung diseases namely lung cancer and tuberculosis are examples of chronic respiratory diseases. Importantly, chronic respiratory diseases are not curable and treatments for acute pathologies are particularly challenging. For that reason, the integration of nanotechnology to existing drugs or for the development of new treatments potentially benefits the therapeutic goals by making drugs more effective and exhibit fewer undesirable side effects to treat these conditions. Moreover, the integration of different nanostructures enables improvement of drug bioavailability, transport and delivery compared to stand-alone drugs in traditional respiratory therapy. Notably, there has been great progress in translating nanotechnology-based cancer therapies and diagnostics into the clinic; however, researchers in recent years have focused on the application of nanostructures in other relevant pulmonary diseases as revealed in our database search. Furthermore, polymeric nanoparticles and micelles are the most studied nanostructures in a wide range of diseases; however, liposomal nanostructures are recognized to be some of the most successful commercial drug delivery systems. In conclusion, this review presents an overview of the recent and relevant research in drug delivery systems for the treatment of different pulmonary diseases and outlines the trends, limitations, importance and application of nanomedicine technology in treatment and diagnosis and future work in this field.

Seroprevalence of anti-SARS-CoV-2 antibodies in Colombia, 2020: A population-based study.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to cause very high morbidity and mortality throughout Latin American countries. However, few population-based seroprevalence surveys have been conducted to quantify attack rates and characterize drivers of transmission. METHODS: We conducted a population-based cross-sectional study to assess the seroprevalence of antibodies against SARS-CoV-2 in ten cities in Colombia between September and December 2020. The study involved multi-stage cluster sampling at each city. Participants provided a serum sample and answered a demographic and risk factor questionnaire. Prior infection by SARS-CoV-2 was ascertained using the "SARS-CoV-2 Total (COV2T) Advia Centaur - Siemens" chemiluminescence assay. FINDINGS: A total of 17863 participants from 7320 households participated in the study. Seroprevalence varied substantially between cities, ranging from 26% (95%CI 23-29 %) in Medellín to 68% (95%CI 62-74 %) in Guapi. There were no differences in seroprevalence by sex, but seropositivity was higher in certain ethnic groups. There was substantial heterogeneity in seroprevalence within cities, driven to a large extent by a strong association between socioeconomic stratum and seropositivity. INTERPRETATION: Colombia has been one of the Latin American countries most affected by the COVID-19 pandemic. This study documented very high attack rates in several Colombian cities by the end of 2020 and identified key drivers of heterogeneities including ethnicity and socioeconomic stratum. Few studies of seroprevalence of SARS-CoV-2 have been conducted in Latin America, and therefore this study contributes to the fundamental understanding of the pandemic in the region. FUNDING: The study was sponsored by, Ministerio de Ciencia y Tecnología e Innovación -CT361/2020, Ministerio de Salud y Protección Social, Fundación Universitaria del Norte, Imperial College of London, Universidad Nacional de Colombia (Sede Medellín), Universidad de Córdoba, California University, Unidad Nacional de Gestión del Riesgo, Centro de Atención y Diagnóstico de Enfermedades Infecciosas -CDI-, Centro Internacional de Entrenamiento e Investigaciones Médicas -CIDEIM-, Departamento Administrativo Nacional de Estadística - DANE, Fondo Nacional de Turismo -FONTUR-, Secretarías de Salud Departamentales, Distritales y Municipales and Instituto Nacional de Salud.

Mindfulness-Based Program for Anxiety and Depression Treatment in Healthcare Professionals: A Pilot Randomized Controlled Trial.

In primary health care, the work environment can cause high levels of anxiety and depression, triggering relevant expert and individual change. Mindfulness-Based Stress Reduction (MBSR) programs reduce signs of anxiety and depression. The purpose of this sub-analysis of the total project, was to equate the effectiveness of the standard MBSR curriculum with the abbreviated version in minimizing anxiety and depression. This randomized controlled clinical trial enrolled 112 mentors and resident specialists from Family and Community Medicine and Nurses (FCMN), distributed across six teaching units (TU) of the Spanish National Health System (SNHS). Experimental group participants received a MBRS training (abbreviated/standard). Depression and anxiety levels were measured with the Goldberg Anxiety and Depression Scale (GADS) at three different time periods during the analysis: before (pre-test) and after (post-test) participation, as well as 3 months after the completion of intervention. Taking into account the pre-test scores as the covariate, an adjusted analysis of covariance (ANCOVA) showed significant depletion in anxiety and depression in general (F (2.91) = 4.488; p = 0.014; η2 = 0.090) and depression in particular (F (2, 91) = 6.653; p = 0.002; η2 = 0.128 at the post-test visit, maintaining their effects for 3 months (F (2.79) = 3.031; p = 0.050; η2 = 0.071-F (2.79) = 2.874; p = 0.049; η2 = 0.068, respectively), which is associated with the use of a standard training program. The abbreviated training program did not have a significant effect on the level of anxiety and depression. The standard MBSR training program had a positive effect on anxiety and depression and promotes long-lasting effects in tutors and resident practitioners. New research is needed to demonstrate the effectiveness of abbreviated versions of training programs.

Effectiveness of a Mindfulness and Self-Compassion Standard Training Program versus an Abbreviated Training Program on Stress in Tutors and Resident Intern Specialists of Family and Community Medicine and Nursing in Spain.

Stress is one of the most common problems among healthcare professionals, as they are exposed to potentially stressful and emotionally challenging situations in the workplace. Mindfulness-based stress reduction (MBSR) training programs have been shown to decrease stress. The objective of this study was to compare the effectiveness of an abbreviated 4-weeks MBSR training program in relation to a standard 8-weeks one on the stress levels. A controlled and randomized clinical trial was designed, in which 112 tutors and resident intern specialists in Family and Community Medicine and Nursing of six Spanish National Health System teaching units (TUs) participated. Participants included in the experimental groups (EGs) received a MBRS training program (standard or abbreviated), while control group (CG) participants did not receive any intervention. The stress levels were assessed by the Perceived Stress Questionnaire (PSQ) in three different moments during the study: before, immediately after, and 3 months after the intervention. Adjusted covariance analysis (ANCOVA), using pretest scores as the covariate, showed a significant reduction in stress (F(2,91) = 5.165; p = 0.008; η2 = 0.102) in the post-test visit, attributable to the implementation of the standard training program, but without the maintenance of its effects over time. No significant impact of the abbreviated training program on stress levels was observed in the intergroup comparison. A standard 8-weeks MBSR training program aimed at tutors and resident intern specialists in Family and Community Medicine and Nursing produces significant improvements in stress levels compared with the abbreviated intervention and no intervention. New studies about abbreviated training programs are needed to provide effective treatments which improve well-being of these professionals.

Mobile application for monitoring patients under home oxygen therapy: a protocol for a randomized controlled trial.

BACKGROUND: Mobile technologies have become capable of changing the paradigm of healthcare services. A clear example is that, nowadays, these technologies are an important instrument for data collection processes, epidemiologic surveillance, health promotion and disease prevention. Therefore, technological tools should be exploited to optimize the monitoring of patients with chronic diseases, including patients who require home oxygen therapy. PURPOSE: The purpose of this study is to determine the efficacy of a mobile application in the clinical monitoring of patients under home oxygen therapy. METHODS: This is a randomized controlled trial includes subjects of 18 years or older diagnosed with Chronic Obstructive Pulmonary Disease (COPD) who are under home oxygen therapy. Subjects will be divided into two arms: the intervention group will include patients who will be monitored with a mobile application, and the control group will include patients monitored by conventional follow-up methods (periodic visits of a respiratory therapist). The following outcome variables will be considered to measure the effect of the intervention: identification of dyspnea self-management, number of acute exacerbations associated with oxygen therapy, and the occurrence of oxygen supply underuse. DISCUSSION: This study is expected to assess the efficacy of a mobile application in the follow up of patients under home oxygen therapy. It will also determine whether the monitoring of a six-month intervention by a team comprising a physician, a nurse and respiratory therapists can decrease acute exacerbations, determine the most appropriate oxygen dose, and identify the underuse of oxygen systems and supplies. TRIAL REGISTRATION: The study has been registered at ClinicalTrials.gov ( NCT04820790 ; date of registration: March 29, 2021).

Frequency and predictive validity of olfactory and taste dysfunction in patients with SARS-CoV-2 infection.

BACKGROUND AND OBJECTIVE: Olfactory and taste dysfunction (OD, TD) have been considered symptoms of SARS-CoV-2 infection. However, its presence in certain populations, especially those with mild clinical symptoms, has not been clarified. The objective was to estimate the frequency of OD and TD, and its predictive validity in patients detected in Primary Care. PATIENTS AND METHODS: A cross-sectional study was carried out in the Spanish National Health System. An epidemiological survey was administered to patients who were requested the PCR test for SARS-CoV-2. Odds ratio (OR) were estimated to measure the magnitude of the association between OD and TD and the existence of SARS-CoV-2 infection. The sensitivity, specificity, and positive and negative predictive values (PPV, NPV) of these symptoms in SARS-CoV-2 infection were calculated. RESULTS: Of 1038 patients screened, 20.1% had SARS-CoV-2 infection. OD and DG were present in 64.4% (95% CI 56.0-72.1) and 56.2% (95% CI 47.9-64.2) of the subjects with infection, respectively. The OR for OD was 12.2 (95% CI 8.26-18.06) and for TD was 7.95 (95% CI 5.48-11.53). TD presented a sensitivity of 41.1% (95% CI 34.4-46.1), a specificity of 91.9% (95% CI 89.8-93.7), a PPV of 56.2% (95% CI48.0-64.2) and a NPV of 86.1% (95% CI 83.6-88.3), while the OD showed a sensitivity of 45.0% (95% CI 37.6-51.5), a specificity of 93.7% (95% CI 91.8-95.0), a PPV of 64.4% (95% CI 56.0-72.1) and a NPV of 87.1% (95% CI 84.7-89.2). CONCLUSIONS: More than half of the subjects with SARS-CoV-2 infection have OD or TD. The presence of OD or TD could be of diagnostic utility due to its ability to predict infection in more than half of the cases.

ANTECEDENTES Y OBJETIVO: La disfunción olfatoria (DO) y gustativa (DG) han demostrado ser síntomas de la infección por SARS-CoV-2. Sin embargo, su presencia en determinadas poblaciones, sobre todo en aquellas con cuadros clínicos leves, aún debe aclararse. El objetivo fue estimar la frecuencia de DO y DG, y su validez predictiva en pacientes detectados en Atención Primaria. PACIENTES Y MÉTODOS: Se realizó un estudio transversal en el Sistema Nacional de Salud español. Se administró una encuesta epidemiológica dirigida a pacientes a los que se les solicitó la prueba PCR para SARS-CoV-2. Se estimaron las odds ratio (OR) para medir la magnitud de la asociación entre la DO y DG y la existencia de infección por SARS-CoV-2. Se calculó la sensibilidad, la especificidad y los valores predictivos positivos (VPP) y negativos (VPN) de estos síntomas en la infección por SARS-CoV-2. RESULTADOS: Se captaron 1.038 pacientes, de los cuales el 20,1% presentaban infección por SARS-CoV-2. Las DO y DG estuvieron presentes en el 64,4% (IC 95% 56,0­72,1) y el 56,2% (IC 95% 47,9­64,2) de los sujetos con infección, respectivamente. La OR para la DO fue de 12,2 (IC 95% 8,26−18,06) y para la DG de 7,95 (IC 95% 5,48−11.53). La DG presentó una sensibilidad del 41,1% (IC 95% 34,4­46,1), una especificidad del 91,9% (IC 95% 89,8­93,7), un VPP del 56,2% (IC 95% 48,0­64,2) y un VPN de 86,1% (IC 95% 83,6­88,3), mientras que la DO mostró una sensibilidad del 45,0% (IC 95% 37,6­51,5), una especificidad del 93,7% (IC 95% 91,8­95,0), un VPP del 64,4% (IC 95% 56,0­72,1) y un VPN del 87,1% (IC 95% 84,7­89,2). CONCLUSIONES: Más de la mitad de los sujetos con infección por SARS-CoV-2 presentan DO o DG. La presencia de DO o de DG podría ser de utilidad diagnostica por su capacidad para predecir la infección en más de la mitad de las ocasiones.

Coping with global uncertainty: Perceptions of COVID-19 psychological distress, relationship quality, and dyadic coping for romantic partners across 27 countries

Following the global outbreak of COVID-19 in March 2020, individuals report psychological distress associated with the ?new normal??social distancing, financial hardships, and increased responsibilities while working from home. Given the interpersonal nature of stress and coping responses between romantic partners, based on the systemic transactional model this study posits that perceived partner dyadic coping may be an important moderator between experiences of COVID-19 psychological distress and relationship quality. To examine these associations, self-report data from 14,020 people across 27 countries were collected during the early phases of the COVID-19 pandemic (March?July, 2020). It was hypothesized that higher symptoms of psychological distress would be reported post-COVID-19 compared to pre-COVID-19 restrictions (Hypothesis 1), reports of post-COVID-19 psychological distress would be negatively associated with relationship quality (Hypothesis 2), and perceived partner DC would moderate these associations (Hypothesis 3). While hypotheses were generally supported, results also showed interesting between-country variability. Limitations and future directions are presented.

Korean traditional foods as antiviral and respiratory disease prevention and treatments: A detailed review.

BACKGROUND: Korean traditional food (KTF), originated from ancestral agriculture and the nomadic traditions of the Korean peninsula and southern Manchuria, is based on healthy food that balances disease prevention and treatment. Fermented foods that include grains, herbs, fruits, and mushrooms are also an important practice in KTF, providing high levels of Lactobacilli, which confer relevant health benefits, including antiviral properties. Some of these probiotics may also protect against the Influenza virus through the modulation of innate immunity. SCOPE AND APPROACH: The emerging of the COVID-19 pandemic, in addition to other diseases of viral origin, and the problems associated with other respiratory disorders, highlight how essential is a healthy eating pattern to strengthen our immune system.Key Findings and Conclusions: The present review covers the information available on edible plants, herbs, mushrooms, and preparations used in KTF to outline their multiple medicinal effects (e.g., antidiabetic, chemopreventive, antioxidative, anti-inflammatory, antibacterial), emphasizing their role and effects on the immune system with an emphasis on modulating properties of the gut microbiota that further support strong respiratory immunity. Potential functional foods commonly used in Korean cuisine such as Kimchi (a mixture of fermented vegetables), Meju, Doenjang, Jeotgal, and Mekgeolli and fermented sauces, among others, are highlighted for their great potential to improve gut-lung immunity. The traditional Korean diet and dietary mechanisms that may target viruses ACE-2 receptors or affect any step of a virus infection pathway that can determine a patient's prognosis are also highlighted. The regular oral intake of bioactive ingredients used in Korean foods can offer protection for some viral diseases, through protective and immunomodulatory effects, as evidenced in pre-clinical and clinical studies.
