The abstract describes the development of a new bioinformatics tool called Time Course Inspector (TCI) for analyzing single-cell time-series datasets. TCI is a user-friendly tool written in R/Shiny that combines time-series analysis with clustering to identify sub-populations of cells with distinct temporal behaviors, which may correspond to different cell fates. The authors demonstrate the utility of TCI by analyzing a single-cell signaling time-series dataset acquired using a fluorescent biosensor. TCI allows users to conveniently inspect time-series data, plot different views, and remove outliers. It also facilitates the interactive exploration of various hierarchical clustering and cluster validation methods. The tool is available on GitHub, and supplementary data are available online.

The human vaginal microbiome (HVM) is crucial to women’s reproductive health, with bacterial vaginosis (BV) being associated with increased risk of sexually transmitted diseases and adverse pregnancy outcomes. This study, published in Integrative Biology, investigates the ecological roles of vaginal bacteria using a new high-throughput technology based on microdroplet co-cultivation. The authors demonstrate that this technology can recapitulate previous findings showing that Lactobacillus jensenii inhibits the growth of Gardnerella vaginalis, a bacterium associated with BV. They also show that the technology can be generalized to other bacterial species, such as Enterococcus faecalis. The study suggests that microdroplet co-cultivation is an effective way to study inter-species interactions in microbial ecosystems.

The study by Zhao, Luo, and Wang (2019) developed a method for analyzing protein dynamics during the sporulation process of budding yeast, Saccharomyces cerevisiae, using an air-enriched microfluidic system. The researchers found that the cell behaviors during sporulation were heterogeneous and that single-cell analysis was necessary to verify the accuracy of protein dynamics. They introduced a ‘data synchronization’ approach, which aligned each cell on a time line according to its own morphological changes, and obtained the dynamic performance of six proteins involved in the yeast sporulation process at the single-cell level. This method provides an efficient way to study protein dynamic behaviors during the sporulation process of yeast.

The title of the abstract is “Erosive pustular dermatosis of the scalp: a diagnostic challenge.” The study was conducted by Ng and Lara Rivero. The study focuses on a rare and poorly understood skin condition called erosive pustular dermatosis (EPD) of the scalp, which can be challenging to diagnose and treat. The authors present two cases of EPD of the scalp, describing the clinical presentation, diagnostic workup, and treatment approach in each case. Both patients responded well to treatment with oral doxycycline and topical corticosteroids. The authors emphasize the importance of considering EPD in the differential diagnosis of scalp lesions, particularly in older adults with a history of scalp psoriasis or other inflammatory skin conditions. They also highlight the need for further research to better understand the pathogenesis, optimal management strategies, and prognosis of EPD of the scalp.

The study found that existing blood pressure thresholds used to diagnose hypertensive disorders of pregnancy (HDP) lack sensitivity in pregnant people with sickle cell disease (SCD). The study suggests that lowering the blood pressure threshold for defining HDP may improve the identification of pregnant individuals with SCD who need increased observation, early delivery consideration, and eclampsia prophylaxis. The study analyzed data from singleton pregnancies in people with SCD delivered at two academic centers between 1990 and 2021. The study found that the systolic blood pressure (SBP) or diastolic blood pressure (DBP) thresholds that maximized sensitivity and specificity in identifying those with new or worsening proteinuria (NWP) were 120 mmHg SBP and 70 mmHg DBP. The existing BP threshold of 140/90 mmHg lacked sensitivity for both genotype groups. The study concludes that lowering the BP threshold for HDP diagnosis may benefit pregnant individuals with SCD.

The study found that endurance athletes who experience functional overreaching, as indicated by reduced performance and well-being, also have altered carbohydrate metabolism during exercise. Specifically, the respiratory exchange ratio and continuous glucose monitor (CGM) readings were suppressed during submaximal stages of exercise in overreached athletes. These findings suggest that monitoring CGM glucose levels during submaximal exercise following standardized nutrition could be a useful tool for detecting overreaching in endurance athletes.

The study investigates the effect of albumin infusion on oxidative albumin modification and albumin binding function in patients with chronic liver failure. The results show that therapeutic albumin solutions have high levels of oxidized albumin species, but albumin infusion in patients did not significantly change oxidized albumin species or albumin binding properties after 24 hours. However, a modified protocol with additional early sampling revealed short-lived changes in oxidized albumin species, but no changes in albumin binding properties. The study concludes that therapeutic albumin infusion transiently changes albumin redox state but does not improve binding function of circulating albumin in chronic liver failure.

This systematic review aimed to identify and evaluate questionnaires that measure the attitudes of healthcare professionals towards the use of restraints in mental healthcare. The review found 23 studies reporting on ten instruments, with significant variation in questionnaire content, terms/constructs, and context. Many studies lacked sufficient details on the report of psychometric properties. The authors conclude that there is a need for updated and adapted instruments with clear definitions and strong psychometric properties to reliably assess attitudes towards coercive measures, which will be important for research and clinical settings.
