Article Synopsis
  • - Genetically-encoded single-cell barcodes can help with tasks like tracing cell lineages and conducting genetic screens, but current methods have limitations in speed and effectiveness.
  • - This study proposes a new method using combinations of fluorescent proteins to create a high-diversity barcode library that allows for non-destructive, quick, and affordable identification of cells.
  • - The researchers successfully tested this method, creating a library of about 150 unique barcodes using 18 fluorescent proteins, and demonstrated its effectiveness for classifying cells and enabling genetic screenings and lineage tracing.

Article Synopsis
  • People who inject drugs generally experience worse health outcomes, and this study aimed to analyze the factors leading to participant attrition in a cohort study in Victoria, Australia.
  • The research utilized data from the Melbourne Injecting Drug User Cohort Study (SuperMIX) and found that 36.8% of participants were lost to follow-up within two years, particularly among younger individuals and those facing social and economic challenges.
  • The results indicate that while attrition rates have been stable, vulnerable groups may be underrepresented in the data, highlighting the need for strategies to keep these high-risk individuals engaged in the study.

  • The study examined the relationship between seasons and variations in serum testosterone levels in a group of 144 men, analyzing various seasonal environmental factors.
  • Results showed no significant differences in testosterone levels or associations with seasonal changes, although a slight inverse correlation was found between temperature, daylight, and testosterone in non-fasting men.
  • The findings suggest that seasonal factors may not significantly impact serum testosterone levels, which could help clarify variables affecting clinical practices and laboratory results.

Background: Choledocholithiasis in children is commonly managed with an "endoscopy-first" (EF) strategy (endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC)). Because ERCP availability is often limited at the end of the week (EoW), we hypothesized that a "surgery-first" (SF) approach (LC with intraoperative cholangiogram (IOC) ± transcystic laparoscopic common bile exploration (LCBDE)) would decrease length of stay (LOS) and time to definitive intervention (TTDI).

Methods: A multicenter, retrospective cohort study was conducted on pediatric patients from 2018 to 2023 with suspected choledocholithiasis.

Article Synopsis
  • Supervised injecting facilities (SIFs) can lower negative consequences for people who inject drugs, but public attitudes towards them can vary and change over time.
  • A national survey in Australia from 2001 to 2019 showed that 54% supported SIFs in 2019, with support linked to factors like education level and drug use, while more men and residents in poorer areas were less likely to support them.
  • Overall, support for SIFs increased modestly during the study period, and improving public understanding of SIFs could help lessen ambivalence and boost support.

Background And Aims: Research examining how alcohol consumption changed across different socio-demographic groups during the pandemic has largely relied upon convenience samples recruited after the onset of the COVID-19 pandemic. The aim of this study was to measure whether the pandemic shifted alcohol consumption in different gender, age and income groups in Australia.

Design, Setting And Participants: This was a longitudinal study using four waves (2017-20) of the annual Household, Income and Labour Dynamics in Australia (HILDA) Survey to compare pre-pandemic consumption (2017-19) with consumption in 2020.

Article Synopsis
  • Over the past two decades, methamphetamine-related deaths in Australia have risen significantly, prompting a comprehensive analysis of mortality trends across various causes from 2001 to 2023.
  • The study found that nearly half of these deaths were due to unintentional drug toxicity, with other causes including self-harm and injuries, revealing fluctuating trends over time with periods of both increase and decrease in mortality rates.
  • The latest data indicate a slight rise in unintentional drug toxicity deaths, a stabilization in intentional self-harm rates, and continued growth in deaths attributed to natural causes like circulatory diseases.

We examine and compare the relationship between minimum wage increases and youth homicide rates in three groups: all youth, White youth only, and Black youth only. Using 2001-2019 mortality data from the National Vital Statistics System (NVSS) for all 50 states and Washington DC, we apply a difference in differences (DD) design to compare the change in youth homicides across states with varying changes in the state-specific minimum wage. With the inclusion of state-specific linear time trends, we find that a $1 increase in minimum wage leads to a significant 4% reduction (RR = 0.

Long non-coding RNAs (lncRNAs) are a group of epigenetic regulators that have been implicated in kidney diseases including acute kidney injury (AKI). However, very little is known about the specific lncRNAs involved in AKI and the mechanisms underlying their pathologic roles. Here, we report a new lncRNA derived from the pseudogene GSTM3P1, which mediates ischemic AKI by interacting with and promoting the degradation of mir-668, a kidney-protective microRNA.
