  • Cerebral blood flow in patients recovered from mild COVID-19. [Journal Article]
    J Neuroimaging. 2023 Jun 02 [Online ahead of print]Sen S, Newman-Norlund R, … Logue M
  • CONCLUSIONS: In this study, lower WM CBF, as well as widespread regional CBF changes identified using quantitative MRI, was found in mild COVID-19 patients. Further studies are needed to determine the reliability of this newly identified COVID-19 brain imaging marker and determine what drives these CBF changes.
  • Intraorbital lymphatic-venous malformation in an adult patient: is sirolimus the key? [Journal Article]
    Orbit. 2023 Jun 01 [Online ahead of print]Ruiz Velasco Santacruz A, Nieva Pascual I, … Pascual González M
  • Intraorbital lymphatic-venous malformations are rare lesions that represent a therapeutic challenge given their location and high rate of recurrence, with only a few cases in adult patients having been published in the literature. We present the case of a 30-year-old male with a right intraorbital lymphatic-venous malformation treated with sirolimus at a dose of 4 mg/day with complete clinical an…
  • Streptococcus suis meningitis in a COVID-19 patient: A case report. [Case Reports]
    Saudi J Anaesth. 2023 Apr-Jun; 17(2):281-283.Viana PB, Penedos C, … Monte R
  • Streptococcus suis is a Gram-positive, facultative anaerobic bacterium and has its natural reservoir in pigs. Infection by this microorganism usually manifests in humans as meningitis, endocarditis, sepsis, and/or arthritis after contact with pigs or pork. Meningitis is a very common manifestation and Streptococcus suis may be considered its second most common cause. A clinical course may manifes…
  • Thematic analysis of national online narratives on regular asymptomatic testing for Covid-19 in schools in England. [Journal Article]
    BMC Public Health. 2023 May 31; 23(1):1028.Taylor-Egbeyemi J, Carter H, Robin C
  • CONCLUSIONS: Our analysis highlighted that alongside well-established barriers to engaging in asymptomatic testing, parents were having to negotiate additional complex decisions around balancing their child's anxiety over testing alongside acknowledgement of the implications of regular testing, such as return to normality and protecting others. Parents and children would benefit from additional practical and social support to facilitate engagement with the schools testing programme.
  • Effects of physical activity on Chinese overseas students' mental health during the COVID-19: A multi-country cross-sectional analysis. [Journal Article]
    PLoS One. 2023; 18(5):e0286321.Nie Y, Ma Y, … Zheng X
  • CONCLUSIONS: COS had several poor mental health conditions during the pandemic. The improvement of PA on COS' psychology was positively effective during the pandemic. Specific types, intensities, durations, and frequencies of PA might have advantages over others for improving COS' mental health during periods of public health emergencies, and the topic may merit interventional study to reveal multiple factors causing COS' psychological burdens and enrich the PA forms for all COS' mental health improvement (i.e., infected, recovered, and asymptomatic COS).
  • Aptamer-based diagnosis of various SARS-CoV2 strains isolated from clinical specimens. [Journal Article]
    Heliyon. 2023 Jun; 9(6):e16458.Moshref ZS, Jalali T, … Mousavi Gargari SL
  • The emergence of the SARS-CoV-2 virus, an unknown strain of coronavirus, has resulted in severe acute respiratory syndrome with high mortality rates worldwide. Due to the possibility of asymptomatic carriers, late diagnosis of infected individuals can lead to uncontrollable transmission of the disease, making early and accurate detection crucial in controlling the spread of the virus. In this stu…
  • Inflammasomes: a rising star on the horizon of COVID-19 pathophysiology. [Review]
    Front Immunol. 2023; 14:1185233.Wang M, Yu F, … Li P
  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a contagious respiratory virus that is the cause of the coronavirus disease 2019 (COVID-19) pandemic which has posed a serious threat to public health. COVID-19 is characterized by a wide spectrum of clinical manifestations, ranging from asymptomatic infection to mild cold-like symptoms, severe pneumonia or even death. Inflammasomes …
  • Acute pancreatitis following SARS-CoV-2 infection: A case report. [Case Reports]
    SAGE Open Med Case Rep. 2023; 11:2050313X231175288.Choden U, Yangzom S, … Wangchuk P
  • The novel coronavirus 2019 (COVID-19) which is caused by severe acute respiratory syndrome coronavirus-2 was first reported from Wuhan, China in December 2019. Since then, it has caused global crisis and it still continues to be a Public Health Emergency of International Concern. Although it primarily involves respiratory system with symptoms ranging from mild to severe acute respiratory distress…
  • Prevalence of SARS-CoV-2 Viremia in Presymptomatic Blood Donors in the Delta and Omicron Variant Eras. [Journal Article]
    Open Forum Infect Dis. 2023 May; 10(5):ofad253.Saá P, Fink RV, … NHLBI Recipient Epidemiology and Donor Evaluation Study-IV-Pediatric (REDS-IV-P)
  • Presymptomatic plasma samples from 1596 donors reporting coronavirus disease 2019 infection or symptoms after blood donation were tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA and anti-S and anti-N antibodies. Prior infection and vaccination both protected from developing SARS-CoV-2 RNAemia and from symptomatic infection. RNAemia rates did not differ in the Delta and…
  • Risk factors associated with indoor transmission during home quarantine of COVID-19 patients. [Journal Article]
    Front Public Health. 2023; 11:1170085.Liu Y, Chai YH, … Wang C
  • CONCLUSIONS: Patients showing negative 2019-nCov antigen tests, being asymptomatic, living in a separate room with a separate toilet, or actively avoiding direct contact with cohabitants were at low risk of family transmission, and the study recommended that avoiding direct contact and residential disinfection could reduce the risk of all cohabitants within the same house being infected with COVID-19.
  • COVID-19 Vaccine Hesitancy among Patients Recovered from COVID-19 Infection in Wuhan, China: A Cross-Sectional Questionnaire Study. [Journal Article]
    JMIR Public Health Surveill. 2023 May 26 [Online ahead of print]Huang Y, Zhang L, … Su X
  • CONCLUSIONS: Among the three major factors of vaccine hesitancy, complacency was proved the most notable one among COVID-19 recovered patients, educational campaigns can focus on raising the awareness of risk of infection and the benefits of vaccination to reduce complacency toward vaccination among them. For COVID-19 recovered patients, improving factors related to convenience such as transportation and environment of vaccination and proving door-to-door service were also necessary to facilitate their vaccination. In addition, addressing the concerns about vaccination of COVID-19 recovered patients could foster trust and promote their vaccination.
  • Rare Rupture of Small 4.3 cm Abdominal Aortic Aneurysm. [Journal Article]
    Am Surg. 2023 May 27 [Online ahead of print]Beeson ST, Faulkner JD, … Eskew TD
  • Abdominal aortic aneurysm (AAA) is a common medical condition with the feared, and often fatal, complication of rupture. The risk of rupture has been well documented to correlate with aneurysm size. It is exceedingly rare for an AAA less than 5 cm to rupture. This case report demonstrates an asymptomatic 4.3 cm AAA that ruptured while admitted to the hospital with COVID-19 pneumonia. The patient …
  • Epidemiology of Respiratory Infections during the COVID-19 Pandemic. [Review]
    Viruses. 2023 May 13; 15(5)Principi N, Autore G, … Esposito S
  • To face the COVID-19 outbreak, a wide range of non-pharmaceutical interventions (NPIs) aimed at limiting the spread of the virus in communities, such as mask-wearing, hand hygiene, social distancing, travel restrictions, and school closures, were introduced in most countries. Thereafter, a significant reduction of new asymptomatic and symptomatic COVID-19 cases occurred, although there were diffe…
  • Infectious SARS-CoV-2 Particles from Rectal Swab Samples from COVID-19 Patients in Brazil. [Journal Article]
    Viruses. 2023 May 11; 15(5)Ribeiro IP, Nascimento LGD, … Fumian TM
  • The main objective of this study was to investigate the dynamic of SARS-CoV-2 viral excretion in rectal swab (RS), saliva, and nasopharyngeal swab (NS) samples from symptomatic patients and asymptomatic contacts. In addition, in order to evaluate the replication potential of SARS-CoV-2 in the gastrointestinal (GI) tract and the excretion of infectious SARS-CoV-2 from feces, we investigated the pr…
