Article Synopsis
  • - The study evaluated how image enhancement techniques impact the reliability of diagnosing dry eye conditions using a portable device called the Smart Eye Camera (SEC).
  • - Analysis of video recordings from 46 patients revealed that certain levels of enhancement led to better consistency in assessments, particularly for corneal fluorescein staining (CFS) and tear break-up time (TBUT).
  • - While moderate enhancement improved diagnostic accuracy, excessive enhancement negatively affected the reliability of other assessments, suggesting the need for careful calibration of image processing.

  • Current methods for measuring bioavailable phosphorus (BAP) in rivers are time-consuming due to sediment separation, which hinders routine analysis.
  • The study proposes a new method using simultaneous multisample ultrasonic extraction to directly measure total BAP in river water without separating sediment.
  • Results showed this new method produced comparable BAP concentrations to traditional methods but significantly reduced analysis time, making it practical for routine river water testing.

  • A study indicated that assisted reproductive technology (ART) might be a risk factor for epimutation-mediated imprinting disorders in mothers aged 30 and older, but its effect on uniparental disomy-mediated imprinting disorders (UPD-IDs) remains uncertain.
  • Researchers assessed 130 patients with aneuploid UPD-IDs and compared ART-conceived birth rates and maternal ages with those in the general population and patients with epi-IDs, finding no significant differences, although UPD-IDs patients tended to be older.
  • The analysis revealed that nearly all ART-conceived births occurred in patients with aneuploid oocyte-derived UPD-IDs (oUPD-IDs), who also had significantly older

  • Silver-Russel syndrome (SRS) is an imprinting disorder marked by growth failure and is diagnosed using the Netchine-Harbison clinical scoring system (NH-CSS) as the consensus clinical criteria.
  • A study of 173 patients meeting the NH-CSS found that 34.1% had loss of methylation of H19/IGF2 or maternal uniparental disomy chromosome 7, while 15% had pathogenic variants or copy number variants.
  • The research highlights the effectiveness of NH-CSS for diagnosis and reveals the genetic diversity within SRS, suggesting the need for more exploration of its "SRS spectrum."

For improving the management of watershed eutrophication, methods for measuring bioavailable phosphorus (BAP) are more important than measurements of total phosphorus (TP). BAP in particulate form (P-BAP) is an important substance that promotes eutrophication, especially during rainy seasons. Only a portion of particulate phosphorus (PP) is taken up by algae that contribute to eutrophication.

SHORT syndrome is a rare developmental disorder frequently associated with growth failure and insulin resistant diabetes mellitus (IRDM). Since GH has a diabetogenic effect, GH therapy has been regarded as a contraindication. We observed a Brazilian girl with SHORT syndrome who received GH therapy from 4 6/12 years of age for SGA short stature.

Article Synopsis
  • Silver-Russell syndrome (SRS) primarily causes growth failure and distinct physical features, often linked to genetic factors like loss of methylation on chromosome 11p15 and maternal uniparental disomy of chromosome 7.
  • A study conducted multigene sequencing on 92 out of 336 SRS patients who had unknown genetic causes and found that none exhibited the usual genetic markers associated with SRS.
  • The research identified a small percentage of patients (4.3%) with pathogenic mutations in genes typically connected to SRS, as well as another 5.4% with variants linked to other genetic syndromes causing growth issues, highlighting the complexity of SRS etiology.

Article Synopsis
  • - Maternal uniparental disomy for chromosome 20 (UPD(20)mat) is a condition linked to unusual gene expression that may cause growth failure and feeding issues, resembling Silver-Russell syndrome (SRS) and small for gestational age-short stature (SGA-SS).
  • - Five patients studied showed either nonmosaic heterodisomy or isodisomy for chromosome 20; they presented symptoms like postnatal growth failure, feeding problems, and abnormal hormonal levels, with several born SGA.
  • - This research suggests UPD(20)mat could explain over 5% of previously unknown causes of SRS and may indicate evolving hypersensitivity in hormone receptor response as the patients age

A crucial issue in neonatal medicine is the impact of preterm birth on the developmental trajectory of the brain. Although a growing number of studies have shown alterations in the structure and function of the brain in preterm-born infants, we propose a method to detect subtle differences in neurovascular and metabolic functions in neonates and infants. Functional near-infrared spectroscopy (fNIRS) was used to obtain time-averaged phase differences between spontaneous low-frequency (less than 0.
