Article Synopsis
  • Systemic Epstein-Barr virus-positive T-cell lymphoma (TCL) in children is rare and often follows an EBV infection, leading to a hyperinflammatory state and poor outcomes, often presenting with hemophagocytic lymphohistiocytosis (HLH) syndrome.
  • The disorder involves a hyperactive immune response and may be linked to genetic alterations on chromosome 22q11.2, increasing the risk of non-Hodgkin lymphoma later in life.
  • A case study of a 21-year-old male who developed HLH from an EBV infection ultimately resulted in a diagnosis of systemic EBV TCL, and despite treatment, he did not survive before receiving a stem cell transplant, highlighting the need for awareness

All definitions of treatment-resistant depression (TRD) require that patients have experienced insufficient benefit from one or more adequate antidepressant trials. Thus, identifying "failed, adequate trials" is key to the assessment of TRD. The Antidepressant Treatment History Form (ATHF) was one of the first and most widely used instruments that provided objective criteria in making these assessments.

Post-transplant lymphoproliferative disorders (PTLDs) are opportunistic malignancies that complicate the success of hematopoietic stem cell or solid organ transplantation. These disorders often arise post-transplant due to the immunosuppression required for minimizing the risk of rejection of donor tissue. First-line treatment of these disorders includes limiting immunosuppression when permissible.

Maternal transmission of microbes occurs across the animal kingdom and is vital for offspring development and long-term health. The mechanisms of this transfer are most well-studied in humans and other mammals but are less well-understood in egg-laying animals, especially those with no parental care. Here, we investigate the transfer of maternal microbes in the oviparous phrynosomatid lizard, Sceloporus virgatus.

Marine resource subsidies alter consumer dynamics of recipient populations in coastal systems. The response to these subsidies by generalist consumers is often not uniform, creating inter- and intrapopulation diet variation and niche diversification that may be intensified across heterogeneous landscapes. We sampled western fence lizards, Sceloporus occidentalis, from Puget Sound beaches and coastal and inland forest habitats, in addition to the lizards' marine and terrestrial prey items to quantify marine and terrestrial resource use with stable isotope analysis and mixing models.

Objective: Characteristics of difficult-to-treat depression (DTD), including infrequent symptom remission and poor durability of benefit, compel reconsideration of the outcome metrics historically used to gauge the effectiveness of antidepressant interventions.

Methods: Self-report and clinician assessments of depression symptom severity were obtained regularly over a 2-year period in a difficult-to-treat depression registry sample receiving treatment as usual (TAU), with or without vagus nerve stimulation (VNS). Alternative outcome metrics for characterizing symptom change were compared in effect size and discriminating power in distinguishing the vagus nerve stimulation + treatment as usual and treatment as usual treatment groups.

Background: In difficult-to-treat depression (DTD) the outcome metrics historically used to evaluate treatment effectiveness may be suboptimal. Metrics based on remission status and on single end-point (SEP) assessment may be problematic given infrequent symptom remission, temporal instability, and poor durability of benefit in DTD.

Methods: Self-report and clinician assessment of depression symptom severity were regularly obtained over a 2-year period in a chronic and highly treatment-resistant registry sample ( = 406) receiving treatment as usual, with or without vagus nerve stimulation.

Animals and their microbiomes exert reciprocal influence; the host's environment, physiology, and phylogeny can impact the composition of the microbiome, while the microbes present can affect host behavior, health, and fitness. While some microbiomes are highly malleable, specialized microbiomes that provide important functions can be more robust to environmental perturbations. Recent evidence suggests Sceloporus virgatus has one such specialized microbiome, which functions to protect eggs from fungal pathogens during incubation.

Long-term studies of animal microbiomes under natural conditions are valuable for understanding the effects of host demographics and environmental factors on host-associated microbial communities, and how those effects interact and shift over time. We examined how the cloacal microbiome of wild Sceloporus virgatus (the striped plateau lizard) varies under natural conditions in a multi-year study. Cloacal swabs were collected from wild-caught lizards across their entire active season and over three years in southeastern Arizona, USA.

Regional anesthesia is frequently employed in efforts to improve postoperative analgesia and reduce opioid requirements following abdominal surgery. The purpose of the current analysis was to determine if there was a difference in postoperative pain and opioid consumption between patients who underwent open total abdominal hysterectomy (TAH) and received ultrasound-guided bilateral transversus abdominis plane (TAP) blocks using either liposomal bupivacaine or ropivacaine. A single-center retrospective analysis was conducted of 215 patients from November 2018 through March 2020 who underwent an open TAH and received bilateral TAP blocks with either liposomal bupivacaine or ropivacaine.

Article Synopsis
  • About one-third of people with major depression don't get better even after trying many treatments, which makes their lives really tough.
  • The idea of "difficult-to-treat depression" (DTD) helps doctors understand and help those who struggle more with their depression.
  • Researchers need to figure out how to properly study and measure the effects of treatments for DTD, since the usual ways of testing might not work for these patients.

Background: Beneficial microbes can be vertically transmitted from mother to offspring in many organisms. In oviparous animals, bacterial transfer to eggs may improve egg success by inhibiting fungal attachment and infection from pathogenic microbes in the nest environment. Vertical transfer of these egg-protective bacteria may be facilitated through behavioral mechanisms such as egg-tending, but many species do not provide parental care.

Three-dimensional (3D) printing is a method by which two-dimensional (2D) virtual data is converted to 3D objects by depositing various raw materials into successive layers. Even though the technology was invented almost 40 years ago, a rapid expansion in medical applications of 3D printing has only been observed in the last few years. 3D printing has been applied in almost every subspecialty of medicine for pre-surgical planning, production of patient-specific surgical devices, simulation, and training.

Article Synopsis
  • The Vagus Nerve Stimulation (VNS) Therapy has been studied for over 20 years to help people with severe depression that doesn't get better with usual treatments.
  • Despite some early hope, a major trial did not show that VNS helps much in the short term, but some long-term studies showed it could be more effective when used for a longer time.
  • The results suggest that future research needs to take into account how long treatment lasts and find better ways to measure if it's really helping people improve.
