Collectins such as surfactant proteins SP-A, SP-D, and mannan-binding lectin (MBL), as well as complement protein Clq are evolutionarily conserved innate immune molecules. They are known to opsonize a range of microbial pathogens (bacteria, fungi, virus, and parasites) and trigger effector clearance mechanisms involving phagocytosis and/or complement activation. Collectins and Cl q have also attracted attention in studies involving pregnancy as they are expressed in the female reproductive tissues during pregnancy; a unique state of immune suppression with increased susceptibility to infectious diseases. Recent studies are beginning to unravel their functional significance in implantation, placentation, pregnancy maintenance and parturition in normal and adverse pregnancies. Collectins and Cl q, expressed in gestational tissues during pregnancy, might alter the status of mother's immune response to the allogenic fetus and the microenvironment, thereby serving as important regulators of fetus-mother interaction. Here, we discuss the functional roles that have been assigned to SP-A, SP-D, MBL and Clq in pregnancy and parturition. (C) 2016 Elsevier GmbH. All rights reserved.

Improving diagnostic accuracy in pregnancy with individualised, gestational age-specific reference intervals

Samuel Dockree, Brian Shine, Lawrence Impey, Lucy Mackillop, Harpal Randeva, Manu Vatish

Summary: This study proposes the use of pregnancy-specific reference intervals (RIs) to interpret investigations during pregnancy, with the aim to improve diagnostic accuracy by using gestational age-specific RIs. By mapping the trajectory of platelets in pregnant women, it is found that platelets below the 3rd centile in early pregnancy can accurately predict thrombocytopaenia at term.

Summary: Solid organ transplant recipients who are fully vaccinated may still be at risk of breakthrough infections from SARS-CoV-2 variants of concern, as shown in this case series. Some patients experienced severe pneumonia and required intensive care and ventilatory support. Younger patients had better outcomes.

Summary: This study presents a rapid and sensitive detection platform for mass-scale screening of SARS-CoV-2 in low-resource settings. The platform combines CRISPR/Cas gene editing technology with isothermal amplification methods to enable detection of SARS-CoV-2 at a single temperature in less than an hour. The authors also provide detailed guidelines for developing and establishing this one-pot assay, and the clinical validation shows high sensitivity and specificity.

Summary: Despite progress in fighting infectious diseases, human adenoviruses (HAdVs) that cause eye infections still pose a significant threat. Conventional diagnostic methods suffer from various issues, and this study presents a novel nanobased immunosensing technique for rapid HAdV detection. The developed assay is simple, reliable, and cost-effective, with a detection limit of 10(2) pfu/mL in less than 2 minutes. It offers a visual color change as a means of detection, demonstrating high specificity and potential as a point-of-care testing device for low-resource settings.

Genetic Variability in the E6, E7, and L1 Genes of Human Papillomavirus Types 16 and 18 among Women in Saudi Arabia

Madain Alsanea, Asma Alsaleh, Dalia Obeid, Faten Alhadeq, Basma Alahideb, Fatimah Alhamlan

Summary: This retrospective cohort study analyzed E6, E7, and L1 gene mutations in cervical specimens collected from Saudi women positive for HPV16 or HPV18 infection. The study found that HPV16 and HPV18 lineages in these specimens were predominantly from Europe. Certain mutations in the E6 and E7 genes of HPV16 were associated with cervical cancer progression and low risk, respectively. Other specific HPV16 and HPV18 mutations were associated with increased risk of cancer, progression, viral load, and age. These findings have important implications for the design of molecular diagnostic tests and vaccination strategies for the Saudi population.

Summary: This study identified mutations in the nucleocapsid protein of SARS-CoV-2 and their association with patient characteristics. Among the identified mutations, R203K was the most common and was associated with reduced risk of ICU admission and death. On the other hand, D63G, R203M, and D377Y were associated with increased risk of ICU admission. The findings highlight the importance of monitoring nucleocapsid protein mutations in understanding viral infection and disease severity.

Summary: The aim of this study was to assess the impact of Omicron subvariants on the mortality of transplant recipients. Our findings revealed that the mortality rate of transplant patients infected with Omicron variants was higher in our cohort compared to other centers, as a limited number of patients received booster vaccines. Optimizing booster vaccination is the most efficient way to improve the mortality of COVID-19 in transplant recipients.

Summary: This study evaluated the efficacy and safety of the combination therapy of casirivimab and imdevimab in patients hospitalized with COVID-19. The results showed that this combination therapy reduced the 28-day mortality rate in patients without detectable antibodies to SARS-CoV-2 infection at baseline, but not in those with detectable antibodies.
