Evaluating the impact of COVID-19 on vertigo and hearing impairment: A post-recovery analysis.

The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has manifested with respiratory symptoms and a spectrum of extra-pulmonary complications. Emerging evidence suggests potential impacts on the auditory and vestibular systems, but the extent and nature of these effects in recovered individuals remain unclear. This study aimed to investigate the prevalence and severity of vertigo and hearing impairment in individuals who have recovered from COVID-19 and to identify potential risk factors associated with these sensory symptoms. A cohort of 250 recovered COVID-19 patients was assessed. Standardized questionnaires, including the Dizziness Handicap Inventory and the Vertigo Symptom Scale, were used to evaluate vertigo. Hearing assessment was conducted using pure-tone audiometry, speech audiometry, tympanometry, and oto-acoustic emissions testing. Logistic regression analysis was performed to assess the association between COVID-19 severity and the occurrence of sensory symptoms, controlling for confounding variables such as age and comorbidities. Of the participants, 10% reported vertigo, varying severity. Hearing assessments revealed that most participants had normal hearing, with an average speech discrimination score of 94.6. Logistic regression analysis indicated a significant association between severe COVID-19 and an increased likelihood of vertigo (OR 2.11, 95% CI 1.02-4.35, P = .043) and hearing impairment (OR 3.29, 95% CI 1.60-6.78, P = .002). This study suggests a significant association between COVID-19 severity and vertigo and hearing impairment prevalence. The findings underscore the importance of sensory symptom assessment in the post-recovery phase of COVID-19, highlighting the need for comprehensive healthcare approaches to manage long-term sequelae.

A review on the current approaches and perspectives of Covid-19 treatment.

At the beginning of 2020, the world was faced with the challenge of the coronavirus disease 2019 (COVID-19) pandemic announced by the WHO on March 11, caused by the betacoronavirus type 2 of the severe acute respiratory syndrome (SARS-CoV-2), which had profound health, sociological and even economic consequences. The quickly implemented and large-scale research resulted in the introduction of widely available vaccines that reduced the further development of the pandemic and antivirals against SARS-CoV-2. Currently, 11 antiviral drugs (Tixagevimab/Cilgavimab, Regdanvimab, Casirivimab/Imdevimab, Sotrovimab, Nirmatrelvir/Ritonavir, Remdesivir, Molnupiravir, Baricitinib, Anakinra, Tocilizumab, Vilobelimab) have been approved or conditionally approved by the European Medicines Agency and/or by the Food and Drug Administration and are available on the pharmaceutical market. The progress in the pathophysiological description of the SARS-CoV-2 infection has allowed the identif i cation of potential targets for drugs against SARS-CoV-2: inhibitors of intracellular entry of the virus (the interaction between the viral spike (S) protein and the cellular angiotensin converting enzyme-2; ACE2 receptor), inhibitors of viral and cellular proteases, and immunomodulatory drugs (antagonists of pro-inf l ammatory cytokines or complement components). Novel agents against SARS-CoV-2 are also sought among the previously routinely used drugs as their repositioning and among plant-derived compounds. It is expected that ongoing research should result in the introduction of new drugs used in COVID-19 in the near future. The article brief l y describes the current epidemiological situation regarding COVID-19 and the currently used vaccines. Moreover, the paper outlines currently used and researched potential drugs in the pharmacotherapy of this disease.

Determining the frequency of thyroid involvement in chest CT scans of COVID-19 patients and its correlation with the severity of lung involvement and survival of patients in 2020.

Introduction: This study aimed to determine the frequency of thyroid gland involvement in chest CT scans of patients with COVID-19 admitted to university-affiliated hospitals and assess its relationship with the severity of lung involvement and patient survival in 2020. Material and methods: In this retrospective cross-sectional study, 1000 PCR-positive patients with COVID-19 who were referred to University-affiliated Hospital in 2020 and had chest CT performed within 72 hours of admission to the hospital were examined. The data was collected by patient file information and CT findings recorded in the PACS system, including thyroid involvement, the severity of lung involvement, and findings related to the death and recovery of patients. Results: The mean age of the examined patients was 56 years. 525 people (52.5%) were men, and 475 (47.5%) were women. 14% had severe pulmonary involvement, and 9.3% had very severe involvement. Moreover, 15.9 percent of them had deceased. 19.7% had focal thyroid involvement, 14% had diffuse involvement, and 66.3% were healthy subjects. Male gender and older age showed a significant relationship with thyroid gland involvement. The severity of lung involvement, the death rate in patients, and hospitalization in ICU were also significantly related to thyroid gland involvement in patients with COVID. Discussion and conclusion: This study highlights the importance of considering thyroid-gland involvement in the comprehensive management of COVID-19 patients. Routine screening and monitoring of thyroid-function may facilitate earlier detection and appropriate management of thyroid-related complications, potentially improving clinical outcomes. This study suggests that in COVID-19 infection the monitoring of thyroid function is prudent, particularly in cases of more serious disease.

Evaluation of choices and time spent on an open online elective course by undergraduate medical students during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic highlighted the weakness of relying on in-person tuition in higher education. Massive open online courses (MOOCs) have been a successful addition to higher education. In this study, educators had to replace a planned elective in the medical curriculum with an online option during the pandemic. The roles of the competency framework of the Health Professions Council of South Africa (HPCSA) (Leader and Manager, Health Advocate, Professional, Communicator, Collaborator, Scholar, and Healthcare Practitioner) were used to guide its development. This elective emphasised the non-clinical roles of medical practitioners and was offered in 2020 and 2021. OBJECTIVES: To describe the choices of third-year medical students and time spent participating in a modified online elective in 2020 and 2021. METHODS: A descriptive cross-sectional study design was used, involving the participation of 629 medical students. Data were collected and analysed from three primary sources: registration data from LinkedIn Learning, data from the Foundation for Professional Development, and self-reported estimates by students of the average time spent on selected courses. Data included identification of the associated competency acquired. Data analysis was conducted using Python, version 3.10.11. RESULTS: The course choices of 629 students were analysed. In 2020 there were 300 participants and in 2021 there were 329. All the students had one compulsory inclusion in the elective (Management and Leadership Short Course for Undergraduate Healthcare Students). Students in both years reported spending the most average time on courses related to clinical knowledge (Healthcare Practitioner), followed by financial literacy and management (Professional), diversity management (Collaborator), and priority actions to identify and/or respond to (Health Advocate). The most popular courses related to the Leader and Manager role were around decision-making in human resources, problem-solving, and managing healthcare teams. Based on the top 10 LinkedIn Learning course selections of both cohorts, there appeared to be a preference for courses that were consistent with the role of medical professionals in practice. The most popular LinkedIn Learning course was The Six Morning Habits of High Performers. CONCLUSION: Students gravitated toward courses aligned with their role as professional doctors within the HPCSA competency framework. More studies are needed to understand how medical students develop the six non-clinical roles in the HPCSA framework and the effectiveness of MOOCs in a medical curriculum.

Clinical findings and electrocardiography predicted mortality among COVID-19 patients with pre-existing hypertension: A cross-sectional study of East Java Province, Indonesia.

OBJECTIVE: To evaluate the factors associated with mortality among coronavirus disease-2019 patients with preexisting hypertension. METHODS: The retrospective, cross-sectional study was conducted from June 15 to July 7, 2021, after approval from Dr Soetomo General Province Hospital, Indonesia, and comprised data from the coronavirus disease-2019 registry in the East Java province of Indonesia from March 2020 to June 2021. Data was collected for adult patients infected by coronavirus disease-2019 with pre-existing hypertension Data was analysed using SPSS 23. RESULTS: Of the 2,732 patients in the registry, 425(15.6%) with median age 56.5 years (interquartile range: 50-64 years) had pre-existing hypertension. Of them, 251(59.06%) were males, and 110(25.9%) had died while in hospital. Mortality was associated with older age; higher white blood cell counts at admission and lower platelet count (p<0.05). In addition, electrocardiogram parameters associated with mortality were faster heart rate and ST abnormality (p<0.05). CONCLUSIONS: Older age, high white blood cell level, lower platelet count, faster heart rate, and ST abnormality at admission were found to be the predictors of mortality among hospitalised coronavirus disease-2019 patients with pre-existing hypertension.

Coinfection of viruses in children with community-acquired pneumonia.

BACKGROUND: Virus, particularly respiratory tract virus infection is likely to co-occur in children with community-acquired pneumonia (CAP). Study focusing on the association between common viruses coinfection and children with CAP is rare. We aimed to study the association between seven common viruses coinfection and clinical/laboratory indexes in children with CAP. METHODS: Six hundred and eighty-four CAP cases from our hospital were enrolled retrospectively. Seven common viruses, including influenza A (FluA), influenza B (FluB), human parainfluenza virus (HPIV), Esptein-Barr virus (EBV), coxsackie virus (CoxsV), cytomegalovirus (CMV), and herpes simplex virus (HSV) were investigated for their associations with CAP. We analyzed the differences of hospitalization days, white blood cell (WBC), c-reactive protein (CRP), platelet (PLT), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), urine red blood cell (uRBC), blood urea nitrogen (BUN), serum creatinine (Scr), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK) and creatine kinase isoenzyme (CKMB) among different viruses coinfection groups by using one-way ANOVA analysis. The differences of clinical/laboratory indexes between ordinary and severe pneumonia groups, as well as non-virus vs multi co-infection viruses groups, and single vs multi co-infection viruses groups by using independent samples T test. Receiver operating characteristic (ROC) curve analyses were applied to test the the predictive value of the clinical/laboratory parameters for the risk of viruses coinfections among CAP. Binary logistic analysis was performed to test the association between various indexes and viruses co-infection. RESULTS: Eighty-four multiple viruses coinfections yielded different prognosis compared with that in 220 single virus coinfection. CMV coinfection was associated with longest hospitalization days, highest ALT, AST and CKMB level. HSV coinfection was associated with highest WBC count, CRP, ESR, and BUN. EBV coinfection was associated with highest PLT and PCT level. FluB coinfection was associated with highest Scr level. CoxsV coinfection was associated with highest uRBC, LDH and CK level. ROC curve analyses showed that CK had the largest area under the curve (AUC: 0.672, p < 10-4) for the risk of viruses coinfections risk in CAP. Significant association between PLT, uRBC, BUN, CK, and CKMB and virus coinfection risk in CAP was observed. CONCLUSIONS: Multiple viruses coinfections indicated different prognosis. Different viruses coinfection yielded varying degrees of effects on the cardiac, liver, kidney and inflamatory injury in CAP. The alterations of clinical/laboratory parameters, particularly CK may be associated with the risk of viruses coinfections in CAP.

Respiratory syncytial virus-associated pneumonia in primary care in Malawi.

OBJECTIVE: To identify the prevalence of respiratory syncytial virus (RSV) in a cohort of children under 5 years of age with World Health Organization (WHO)-defined pneumonia and the factors associated with developing severe RSV-associated community-acquired pneumonia (CAP) in primary care in a single centre in Northern Malawi. METHODS: The BIOmarkers TO diagnose PnEumonia (BIOTOPE) study was a prospective cohort study conducted from March to June 2016 that took place in a primary care centre in Northern Malawi. Data from this study was used to identify the characteristics of children under 5 years of age who presented with RSV and WHO-defined CAP. Means, standard deviations, medians and ranges were calculated for continuous variables. A univariate logistic regression was performed to examine the potential predictor variables. RESULTS: Four hundred and ninety-four infants presented with CAP and were eligible for inclusion in the study; RSV infection was detected in 205 (41.6%) of the infants. Eight factors were associated with increased risk for RSV CAP in the univariate model: age, born at term, presenting for care in June, crowded living environment, not being exclusively breastfed, not having received zinc or vitamin A supplementation in the last six months. Infants with RSV were more likely to have an oxygen saturation ≤92% compared to infants with other causes of pneumonia and more likely to have severe pneumonia as defined by the WHO. CONCLUSION: This study supports that RSV-associated CAP is linked to modifiable and non-modifiable risk factors; further research is indicated to determine which interventions would be most impactful. Developing and implementing an infant or maternal vaccine could be a cost-effective way to prevent RSV-associated CAP and mortality in developing nations. More research is needed to understand seasonal patterns of CAP and research over extended periods can offer valuable insights on host, environmental and pathogen-specific factors that contribute to RSV-associated CAP.

Endothelin Level in Menopausal Women with Comorbidity of the Acute Phase Middle Severity COVID-19 with Arterial Hypertension and Type 2 Diabetes Mellitus.

The levels of endothelins were assessed in menopausal women with arterial hypertension (AH) and type 2 diabetes mellitus (T2DM) in the acute phase of the moderate COVID-19. Women under observation (age 45-69 years) were divided into two groups. Control group consisted of women (n=16) who did not have COVID-19, were not vaccinated, and had no antibodies to SARS-CoV-2 (IgG). The main group included women (n=63) in the acute phase of the moderate COVID-19 accompanied by pneumonia. According to the clinical and anamnestic data analysis, the main group was divided into subgroups: without AH and T2DM (n=21); with AH and without T2DM (n=32); and with AH and T2DM (n=10). The parameters of clinical blood analysis, as well as endothelin-1, endothelin-2, and endothelin-3 levels were assessed. In women with a moderate COVID-19, the endothelin-1 and endothelin-2 levels were increased compared to the control regardless of AH and T2DM status. We found no statistically significant differences in the studied parameters of endothelial dysfunction between the subgroups of menopausal women in the acute phase of the moderate COVID-19.

Research on the global trends of COVID-19 associated acute kidney injury: a bibliometric analysis.

Critically ill COVID-19 patients may exhibit various clinical symptoms of renal dysfunction including severe Acute Kidney Injury (AKI). Currently, there is a lack of bibliometric analyses on COVID-19-related AKI. The aim of this study is to provide an overview of the current research status and hot topics regarding COVID-19 AKI. The literature was retrieved from the Web of Science Core Collection (WoSCC) database. Subsequently, we utilized Microsoft Excel, VOSviewer, Citespace, and Pajek software to revealed the current research status, emerging topics, and developmental trends pertaining to COVID-19 AKI. This study encompassed a total of 1507 studies on COVID-19 AKI. The United States, China, and Italy emerged as the leading three countries in terms of publication numbers, contributing 498 (33.05%), 229 (15.20%), and 140 (9.29%) studies, respectively. The three most active and influential institutions include Huazhong University of Science and Technology, Wuhan University and Harvard Medical School. Ronco C from Italy, holds the record for the highest number of publications, with a total of 15 papers authored. Cheng YC's work from China has garnered the highest number of citations, totaling 470 citations. The co-occurrence analysis of author keywords reveals that 'mortality', 'intensive care units', 'chronic kidney disease', 'nephrology', 'renal transplantation', 'acute respiratory distress syndrome', and 'risk factors' emerge as the primary areas of focus within the realm of COVID-19 AKI. In summary, this study analyzes the research trends in the field of COVID-19 AKI, providing a reference for further exploration and research on COVID-19 AKI mechanisms and treatment.

Sudden Sensorineural Hearing Loss Before COVID-19, During COVID-19, and After Inactivated Vaccination: Experience From a Tertiary Referral Center in China.

OBJECTIVE: The purpose of this study was to investigate the incidence rate and audiological characteristics of sudden sensorineural hearing loss (SSHL) before the COVID-19 pandemic, during the COVID-19 pandemic, and after inactivated vaccination, and to analyze whether the novel coronavirus or inactivated vaccination have an impact on hearing loss. MATERIALS AND METHODS: The clinical data of all patients who visited the hospital in July 2019 (before pandemic), July 2020 (during pandemic) and July 2021 (after the inactivated vaccination at least the first basic dose of COVID-19 vaccination) were retrospective analyzed. All patients diagnosed with sudden sensorineural hearing loss in these three periods were screened, and their incidence rate, hearing characteristics, and prognosis were compared. RESULTS: Overall, the incidence rates of sudden hearing loss in July 2019, July 2020, and July 2021 were 0.59, 0.60, and 0.52% (25 of 4225, 20 of 3322, 28 of 5432), respectively, without significant difference ( χ2 = 0.372, p = 0.830). A significant difference was noted in the incidence of hypertension ( p = 0.02), whereas no significant difference was noted in age ( p = 0.591, p = 0.66), sex ( p = 0.19, p = 0.08), main symptoms ( p = 0.18, p = 0.15), side ( p = 0.483, p = 0.89), audiogram shape ( p = 0.56, p = 0.989), average hearing threshold of affected frequency ( p = 0.81, p = 0.89), average hearing threshold of normal ear affected frequency ( p = 0.65, p = 0.68), average hearing threshold of affected frequency after treatment ( p = 0.49, p = 0.38), days between symptoms onset and hospital visit ( p = 0.62, p = 0.85), treatment plan ( p = 0.551, p = 0.474), and effectiveness ( p = 0.104, p = 0.050). CONCLUSION: Our study failed to find a correlation between the novel coronavirus pandemic and inactivated vaccination and SSHL, and there was no direct evidence supporting that COVID-19 or inactivated vaccination had an impact on the incidence rate and prognosis of SSHL patients.

Lessons learned from the COVID-19 pandemic: The importance of physician leadership in responding to rural community ecosystem disruptions.

INTRODUCTION: The COVID-19 pandemic presented an unprecedented challenge for rural family physicians. The lessons learned over the course of 2 years have potential to help guide responses to future ecosystem disruption. This qualitative study aims to explore the leadership experiences of rural Canadian family physicians during the COVID-19 pandemic as both local care providers and community health leaders and to identify potential supports and barriers to physician leadership. METHODS: Semi-structured, virtual, qualitative interviews were completed with participants from rural communities in Canada from December 2021 to February 2022 inclusive. Participant recruitment involved identifying seed contacts and conducting snowball sampling. Participants were asked about their experiences during the COVID-19 pandemic, including the role of physician leadership in building community resilience. Data collection was completed on theoretical saturation. Data were thematically analysed using NVivo 12. RESULTS: Sixty-four participants took part from 22 rural communities in 4 provinces. Four key factors were identified that supported physician leadership towards rural resilience during ecosystem disruption: (1) continuity of care, (2) team-based care models, (3) physician well-being and (4) openness to innovative care models. CONCLUSION: Healthcare policy and practice transformation should prioritise developing opportunities to strengthen physician leadership, particularly in rural areas that will be adversely affected by ecosystem disruption. INTRODUCTION: La pandémie de COVID-19 a représenté un défi sans précédent pour les médecins de famille en milieu rural. Les leçons tirées au cours des deux années écoulées peuvent aider à orienter les réponses aux futures perturbations de l'écosystème. Cette étude qualitative vise à explorer les expériences de leadership des médecins de famille ruraux canadiens pendant la pandémie de COVID-19, en tant que prestataires de soins locaux et chefs de file de la santé communautaire, et à identifier les soutiens et les obstacles potentiels au leadership des médecins. MTHODES: Des entretiens qualitatifs virtuels semi-structurés ont été réalisés avec des participants issus de communautés rurales du Canada entre décembre 2021 et février 2022 inclus. Le recrutement des participants a consisté à identifier des contacts de base et à procéder à un échantillonnage boule de neige. Les participants ont été interrogés sur leurs expériences durant la pandémie de COVID-19, notamment sur le rôle du leadership des médecins dans le renforcement de la résilience des communautés. La collecte des données s'est achevée après saturation théorique. Les données ont été analysées thématiquement à l'aide de NVivo 12. RSULTATS: Soixante-quatre participants provenant de 22 communautés rurales de quatre provinces ont pris part à l'étude. Quatre facteurs clés ont été identifiés pour soutenir le leadership des médecins en faveur de la résilience rurale en cas de perturbation de l'écosystème: (1) la continuité des soins, (2) les modèles de soins en équipe, (3) le bien-être des médecins et (4) l'ouverture à des modèles de soins novateurs. CONCLUSION: La politique de santé et la transformation des pratiques devraient donner la priorité au développement d'opportunités pour renforcer le leadership des médecins, en particulier dans les zones rurales qui seront négativement affectées par la perturbation de l'écosystème.

Ventilator-Associated Pneumonia, Ventilator-Associated Events, and Nosocomial Respiratory Viral Infections on the Leeside of the Pandemic.

The COVID-19 pandemic has had an unprecedented impact on population health and hospital operations. Over 7 million patients have been hospitalized for COVID-19 thus far in the United States alone. Mortality rates for hospitalized patients during the first wave of the pandemic were > 30%, but as we enter the fifth year of the pandemic hospitalizations have fallen and mortality rates for hospitalized patients with COVID-19 have plummeted to 5% or less. These gains reflect lessons learned about how to optimize respiratory support for different kinds of patients, targeted use of therapeutics for patients with different manifestations of COVID-19 including immunosuppressants and antivirals as appropriate, and high levels of population immunity acquired through vaccines and natural infections. At the same time, the pandemic has helped highlight some longstanding sources of harm for hospitalized patients including hospital-acquired pneumonia, ventilator-associated events (VAEs), and hospital-acquired respiratory viral infections. We are, thankfully, on the leeside of the pandemic at present; but the large increases in ventilator-associated pneumonia (VAP), VAEs, bacterial superinfections, and nosocomial respiratory viral infections associated with the pandemic beg the question of how best to prevent these complications moving forward. This paper reviews the burden of hospitalization for COVID-19, the intersection between COVID-19 and both VAP and VAEs, the frequency and impact of hospital-acquired respiratory viral infections, new recommendations on how best to prevent VAP and VAEs, and current insights into effective strategies to prevent nosocomial spread of respiratory viruses.

Changes in respiratory infection trends during the COVID-19 pandemic in patients with haematologic malignancy.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has changed respiratory infection patterns globally. However, its impact on community-acquired pneumonia (CAP) in high-risk patients with haematological malignancies (HM) is uncertain. We aimed to examine how community-acquired pneumonia aetiology in patients with haematological malignancies changed during the COVID-19 pandemic. METHODS: This was a retrospective study that included 524 patients with haematological malignancies hospitalised with community-acquired pneumonia between March 2018 and February 2022. Patients who underwent bronchoscopy within 24 h of admission to identify community-acquired pneumonia aetiology were included. Data on patient characteristics, laboratory findings, and results of bronchioalveolar lavage fluid cultures and polymerase chain reaction tests were analysed and compared to identify changes and in-hospital mortality risk factors. RESULTS: Patients were divided into the 'pre-COVID-19 era' (44.5%) and 'COVID-19 era' (55.5%) groups. The incidence of viral community-acquired pneumonia significantly decreased in the COVID-19 era, particularly for influenza A, parainfluenza, adenovirus, and rhinovirus (pre-COVID-19 era vs. COVID-19 era: 3.0% vs. 0.3%, P = 0.036; 6.5% vs. 0.7%, P = 0.001; 5.6% vs. 1.4%, P = 0.015; and 9.5% vs. 1.7%, P < 0.001, respectively), whereas that of bacterial, fungal, and unknown community-acquired pneumonia aetiologies remain unchanged. Higher Sequential Organ Failure Assessment scores and lower platelet counts correlated with in-hospital mortality after adjusting for potential confounding factors. CONCLUSIONS: In the COVID-19 era, the incidence of community-acquired pneumonia with viral aetiologies markedly decreased among patients with haematological malignancies, with no changes in the incidence of bacterial and fungal pneumonia. Further studies are required to evaluate the impact of COVID-19 on the prognosis of patients with haematological malignancies and community-acquired pneumonia.

Severe Human Parainfluenza Virus Community- and Healthcare-Acquired Pneumonia in Adults at Tertiary Hospital, Seoul, South Korea, 2010-2019.

The characteristics of severe human parainfluenza virus (HPIV)-associated pneumonia in adults have not been well evaluated. We investigated epidemiologic and clinical characteristics of 143 patients with severe HPIV-associated pneumonia during 2010-2019. HPIV was the most common cause (25.2%) of severe virus-associated hospital-acquired pneumonia and the third most common cause (15.7%) of severe virus-associated community-acquired pneumonia. Hematologic malignancy (35.0%), diabetes mellitus (23.8%), and structural lung disease (21.0%) were common underlying conditions. Co-infections occurred in 54.5% of patients admitted to an intensive care unit. The 90-day mortality rate for HPIV-associated pneumonia was comparable to that for severe influenza virus-associated pneumonia (55.2% vs. 48.4%; p = 0.22). Ribavirin treatment was not associated with lower mortality rates. Fungal co-infections were associated with 82.4% of deaths. Clinicians should consider the possibility of pathogenic co-infections in patients with HPIV-associated pneumonia. Contact precautions and environmental cleaning are crucial to prevent HPIV transmission in hospital settings.

Resurgence of common respiratory viruses in patients with community-acquired pneumonia (CAP)-A prospective multicenter study.

BACKGROUND: Community-acquired pneumonia (CAP) is a major global cause of death and hospitalization. Bacteria or community-acquired viruses (CARVs) cause CAP. COVID-19 associated restrictions effectively reduced the circulation of CARVs. OBJECTIVES: The aim of this study was to analyze the proportion of CARVs in adult patients with CAP from mid-2020 to mid-2023. Specifically, we aimed to compare the rate of influenza virus, SARS-CoV-2, and RSV detections in patients aged 18-59 years and ≥60 years. STUDY DESIGN: We analyze the proportion of 21 community-acquired respiratory viruses (CARVs) and three atypical bacteria (Bordetella pertussis, Legionella pneumophila, and Mycoplasma pneumoniae) in nasopharyngeal swab samples using molecular multiplex methods within the prospective, multicentre, multinational study of the German study Group CAPNETZ. We used stringent inclusion criteria throughout the study. RESULTS: We identified CARVs in 364/1,388 (26.2 %) patients. In detail, we detected SARS-CoV-2 in 210/1,388 (15.1 %), rhino-/enterovirus in 64/1,388 (4.6 %), influenza virus in 23/1,388 (1.6 %) and RSV in 17/1,388 (1.2 %) of all patients. We detected RSV and influenza more frequently in patients ≥60 years, especially in 22/23 compared to the previous season. None of the atypical bacteria were detected. CONCLUSIONS: Beginning in 2023, we demonstrate a re-emergence of CARVs in CAP patients. Effective vaccines or specific antiviral therapies for more than two thirds of the detected viral infections are currently available. High detection rates of vaccine-preventable viruses in older age groups support targeted vaccination campaigns.

Effects of SARS-COVID-19 lockdown on menstrual patterns: A transversal large sample survey.

OBJECTIVE: To elucidate the presence, importance, and characteristics of menstrual changes related to stressful circumstances during the COVID-19 lockdown in Spain. STUDY DESIGN: An online survey was administered in Spain to menstruating women aged 15-55 who had not contracted COVID-19. It collected information on activities during the lockdown, sexual activity, perceptions of emotional status, any changes in menstrual characteristics, and impact on quality of life. The analysis of menstrual changes was limited to responders who did not use hormonal contraception. RESULTS: A total of 6449 women answered the survey, and 4989 surveys were valid for the final analysis. 92.3% of women had at least one menstruation period during the lockdown, while 7.7% had amenorrhea. Quality of life (QoL) associated with menstruation worsened in 19% of women, did not change in 71.7%, and improved in 1.6%. For 50.1% of the women, global QoL worsened during the lockdown; 41.3% remained about the same and 8.7% reported improvement. Sexual activity during the lockdown decreased in 49.8% of the respondents, remained unchanged in 40.7%, and increased in 9.5%. As far the menstrual changes are concerned, there were no statistically significant differences in amenorrhea incidence, regularity of the menstrual cycle, or the amount or duration of menstrual bleeding in non-hormonal contraceptive users when evaluated by the length and characteristics of isolation, the perception of exposure to COVID-19 and the economic or employment situation. Conversely, we found statistically significant differences according to the intensity of changes in emotional status due to lockdown stressors and changes in regularity, duration, and heaviness of menstruation. CONCLUSION: Changes in emotional status, but not the length and intensity of the isolation or exposure to the disease, significantly influenced menstrual disturbances during the COVID-19 lockdown.

Phase I/II clinical trial of efficacy and safety of EGCG oxygen nebulization inhalation in the treatment of COVID-19 pneumonia patients with cancer.

BACKGROUND: The antiviral drug Nirmatrelvir was found to be a key drug in controlling the progression of pneumonia during the infectious phase of COVID-19. However, there are very few options for effective treatment for cancer patients who have viral pneumonia. Glucocorticoids is one of the effective means to control pneumonia, but there are many adverse events. EGCG is a natural low toxic compound with anti-inflammatory function. Thus, this study was designed to investigate the safety and efficacy of epigallocatechin-3-gallate (EGCG) aerosol to control COVID-19 pneumonia in cancer populations. METHODS: The study was designed as a prospective, single-arm, open-label phase I/II trial at Shandong Cancer Hospital and Institute, between January 5, 2023 to March 31,2023 with viral pneumonia on radiographic signs after confirmed novel coronavirus infection. These patients were treated with EGCG nebulization 10 ml three times daily for at least seven days. EGCG concentrations were increased from 1760-8817umol/L to 4 levels with dose escalation following a standard Phase I design of 3-6 patients per level. Any grade adverse event caused by EGCG was considered a dose-limiting toxicity (DLT). The maximum tolerated dose (MTD) is defined as the highest dose with less than one-third of patients experiencing dose limiting toxicity (DLT) due to EGCG. The primary end points were the toxicity of EGCG and CT findings, and the former was graded by Common Terminology Criteria for Adverse Events (CTCAE) v. 5.0. The secondary end point was the laboratory parameters before and after treatment. RESULT: A total of 60 patients with high risk factors for severe COVID-19 pneumonia (factors such as old age, smoking and combined complications)were included in this phase I-II study. The 54 patients in the final analysis were pathologically confirmed to have tumor burden and completed the whole course of treatment. A patient with bucking at a level of 1760 umol/L and no acute toxicity associated with EGCG has been reported at the second or third dose gradients. At dose escalation to 8817umol/L, Grade 1 adverse events of nausea and stomach discomfort occurred in two patients, which resolved spontaneously within 1 hour. After one week of treatment, CT showed that the incidence of non-progression of pneumonia was 82% (32/39), and the improvement rate of pneumonia was 56.4% (22/39). There was no significant difference in inflammation-related laboratory parameters (white blood cell count, lymphocyte count, IL-6, ferritin, C-reactive protein and lactate dehydrogenase) before and after treatment. CONCLUSION: Aerosol inhalation of EGCG is well tolerated, and preliminary investigation in cancer population suggests that EGCG may be effective in COVID-19-induced pneumonia, which can promote the improvement of patients with moderate pneumonia or prevent them from developing into severe pneumonia.

Hospital Outcomes Among Children With Congenital Heart Disease and Adenovirus Pneumonia.

BACKGROUND: The aim of the study is to evaluate the mortality risk factors and hospitalization outcomes of adenovirus pneumonia in pediatric patients with congenital heart disease. METHODS: In this retrospective multicenter cohort study utilizing the Pediatric Health Information System database, we analyzed congenital heart disease patients with adenovirus pneumonia from January 2004 to September 2018, categorizing them into shunts, obstructive lesions, cyanotic lesions and mixing lesions. Multivariate logistic regression analysis was employed to identify mortality risk factors with 2 distinct models to mitigate collinearity issues and the Mann-Whitney U test was used to compare the hospital length of stay between survivors and nonsurvivors across these variables. RESULTS: Among 381 patients with a mean age of 3.2 years (range: 0-4 years), we observed an overall mortality rate of 12.1%, with the highest mortality of 15.1% noted in patients with shunts. Model 1 identified independent factors associated with increased mortality, including age 0-30 days (OR: 8.13, 95% CI: 2.57-25.67, P < 0.005), sepsis/shock (OR: 3.34, 95% CI: 1.42-7.83, P = 0.006), acute kidney failure (OR: 4.25, 95% CI: 2.05-13.43, P = 0.0005), shunts (OR: 2.95, 95% CI: 1.14-7.67, P = 0.03) and cardiac catheterization (OR: 6.04, 95% CI: 1.46-24.94, P = 0.01), and Model 2, extracorporeal membrane oxygenation (OR: 3.26, 95% CI: 1.35-7.87, P = 0.008). Nonsurvivors had a median hospital stay of 47 days compared to 15 days for survivors. CONCLUSION: The study revealed a 12.1% mortality rate in adenoviral pneumonia among children with congenital heart disease, attributed to risk factors such as neonates, sepsis, acute kidney failure, shunts, cardiac catheterization, extracorporeal membrane oxygenation use and a 3-fold longer hospital stay for nonsurvivors compared to survivors.

Gestational diabetes mellitus in the era of COVID-19: Challenges and opportunities.

BACKGROUND AND AIMS: The impact of the coronavirus disease 2019 (COVID-19) pandemic on pregnant women, especially those with gestational diabetes mellitus (GDM), has yet to be fully understood. This review aims to examine the interaction between GDM and COVID-19 and to elucidate the pathophysiological mechanisms underlying the comorbidity of these two conditions. METHODS: We performed a systematic literature search using the databases of PubMed, Embase, and Web of Science with appropriate keywords and MeSH terms. Our analysis included studies published up to January 26, 2023. RESULTS: Despite distinct clinical manifestations, GDM and COVID-19 share common pathophysiological characteristics, which involve complex interactions across multiple organs and systems. On the one hand, infection with severe acute respiratory syndrome coronavirus 2 may target the pancreas and placenta, resulting in ß-cell dysfunction and insulin resistance in pregnant women. On the other hand, the hormonal and inflammatory changes that occur during pregnancy could also increase the risk of severe COVID-19 in mothers with GDM. Personalized management and close monitoring are crucial for treating pregnant women with both GDM and COVID-19. CONCLUSIONS: A comprehensive understanding of the interactive mechanisms of GDM and COVID-19 would facilitate the initiation of more targeted preventive and therapeutic strategies. There is an urgent need to develop novel biomarkers and functional indicators for early identification and intervention of these conditions.
