Article Synopsis
  • Human environmental DNA (eDNA) shows promise as a forensic tool for detecting human DNA in aquatic environments but hasn't been thoroughly utilized yet.
  • A preliminary study tested the persistence and detection of human eDNA using water samples from both freshwater and saltwater, with results indicating varying degrees of detectability over time.
  • The findings suggest that incorporating human eDNA analysis could significantly aid law enforcement in improving investigation accuracy, especially in cases linked to aquatic settings, but further research is essential for optimization.

Article Synopsis
  • The paper discusses the challenges of identifying human remains found at Sandy Point, Victoria, where both circumstantial information and preservation were lacking, complicating the identification process.
  • Traditional methods like visual or fingerprint identification were impossible due to the state of the remains, leading to the use of a range of techniques including radiocarbon dating and genetic analysis.
  • Ultimately, an interdisciplinary approach combining forensic anthropology, odontology, history, and genealogy successfully identified the remains as belonging to Christopher Luke Moore, who drowned in 1928.

The successful application of Forensic Investigative Genetic Genealogy (FIGG) to the identification of unidentified human remains and perpetrators of serious crime has led to a growing interest in its use internationally, including Australia. Routinely, FIGG has relied on the generation of high-density single nucleotide polymorphism (SNP) profiles from forensic samples using whole genome array (WGA) (∼650,000 or more SNPs) or whole genome sequencing (WGS) (millions of SNPs) for DNA segment-based comparisons in commercially available genealogy databases. To date, this approach has required DNA of a quality and quantity that is often not compatible with forensic samples.

Background: Almost half of patients with Crohn's disease (CD) require bowel surgeries in their lifetime. Due to the high risk of postoperative disease recurrence and high rate of previous antitumor necrosis factor (anti-TNF) failure, often alternative therapy options such as ustekinumab (UST) and vedolizumab (VDZ) are used. We aimed to evaluate the efficacy of UST and VDZ among postoperative CD patients as postoperative prophylaxis and rescue therapy.

Previous studies have shown that environmental DNA (eDNA) from human sources can be recovered from natural bodies of water, and the generation of DNA profiles from such environmental samples may assist in forensic investigations. However, fundamental knowledge gaps exist around the factors influencing the probability of detecting human eDNA and the design of optimal sampling protocols. One of these is understanding the particle sizes eDNA signals are most strongly associated with and the most appropriate filter size needed for efficiently capturing eDNA particles.

Artificial intelligence/machine learning tools are being created for use in pathology. Some examples related to lung pathology include acid-fast stain evaluation, programmed death ligand-1 (PDL-1) interpretation, evaluating histologic patterns of non-small-cell lung carcinoma, evaluating histologic features in mesothelioma associated with adverse outcomes, predicting response to anti-PDL-1 therapy from hematoxylin and eosin-stained slides, evaluation of tumor microenvironment, evaluating patterns of interstitial lung disease, nondestructive methods for tissue evaluation, and others. There are still some frameworks (regulatory, workflow, and payment) that need to be established for these tools to be integrated into pathology.

Background: CD8+ tumor-infiltrating lymphocyte (TIL) predicts response to anti-PD-(L)1 therapy. However, there remains no standardized method to assess CD8+ TIL in melanoma, and developing a specific, cost-effective, reproducible, and clinically actionable biomarker to anti-PD-(L)1 remains elusive. We report on the development of automatic CD8+ TIL density quantification via whole slide image (WSI) analysis in advanced melanoma patients treated with front-line anti-PD-1 blockade, and correlation immunotherapy response.

Background: Informativeness, in the context of clinical trials, defines whether a study's results definitively answer its research questions with meaningful next steps. Many clinical trials end uninformatively. Clinical trial protocols are required to go through reviews in regulatory and ethical domains: areas that focus on specifics outside of trial design, biostatistics, and research methods.

The mosquito family Culicidae is divided into 2 subfamilies named the Culicinae and Anophelinae. Nix, the dominant male-determining factor, has only been found in the culicines Aedes aegypti and Aedes albopictus, 2 important arboviral vectors that belong to the subgenus Stegomyia. Here we performed sex-specific whole-genome sequencing and RNAseq of divergent mosquito species and explored additional male-inclusive datasets to investigate the distribution of Nix.

Article Synopsis
  • This study investigates whether multifocal lung squamous cell carcinomas (LSCCs) represent separate primary cancers or spread from one tumor using whole exome sequencing (WES) and morphologic assessments.
  • The analysis involved 20 tumor pairs, revealing that 11 cases were classified as separate primary lung cancers (SPLCs) while 7 were classified as intrapulmonary metastases (IPMs), highlighting significant genomic and immunogenic differences.
  • The results showed poor agreement (58.3%) between histological evaluations by pathologists and WES findings, suggesting that relying solely on morphologic assessments for staging multifocal LSCCs is unreliable and that genomic analyses should be prioritized.

Background: Medications for opioid use disorder (MOUD) such as buprenorphine is effective for treating opioid use disorder (OUD). START NOW (SN) is a manualized, skills-based group psychotherapy originally developed and validated for the correctional population and has been shown to result in reduced risk of disciplinary infractions and future psychiatric inpatient days with a dose response effect. We investigate whether adapted START NOW is effective for treating OUD in a MOUD office-based opioid treatment (OBOT) setting in this non-inferiority clinical trial.

The organ shortage continues to present problems around the world including the United States. In response, some countries have switched from an opt-in organ donor registry to an opt-out registry. The United States currently utilizes an opt-in registry where an individual is not considered an organ donor until they register their intentions.

Self-reported lost memory of child sexual abuse (CSA) can be mistaken for "repressed memory." Based on our longitudinal studies of memory and disclosure in child maltreatment victims who are now adults, we discuss findings relevant to "repressed memory cases." We examined relations between self-report of temporarily lost memory of CSA (subjective forgetting) and memory accuracy for maltreatment-related experiences (objective memory).

In legal cases regarding child sexual abuse (CSA), children have various options, such as to disclose or deny maltreatment. When interviewed in adulthood, their accounts may be consistent with their childhood responses. Alternatively, denial in childhood could be followed in adulthood by disclosure ("deferred disclosure"), confirming previous suspicions.

Conventional mosquito marking technology for mark-release-recapture (MRR) is quite limited in terms of information capacity and efficacy. To overcome both challenges, we have engineered, lab-tested, and field-evaluated a new class of marker particles, in which synthetic, short DNA oligonucleotides (DNA barcodes) are adsorbed and protected within tough, crosslinked porous protein microcrystals. Mosquitoes self-mark through ingestion of microcrystals in their larval habitat.

The literature on social media suggests a link between use and negative mental health consequences. Numerous theoretical perspectives have attempted to explain the underlying mechanisms for this relationship but are lacking a clear explanation for why some individuals may be negatively impacted by their social media use. Despite a plethora of research on this relationship, minimal research has examined the act of limiting social media use as a promotional behavior.
