ISG15 deficiency is a rare disease caused by autosomal recessive variants in the gene, which encodes the ISG15 protein. The ISG15 protein plays a dual role in both the type I and II interferon (IFN) immune pathways. Extracellularly, the ISG15 protein is essential for IFN-γ-dependent anti-mycobacterial immunity, while intracellularly, ISG15 is necessary for USP18-mediated downregulation of IFN-α/β signalling.

Article Synopsis
  • A novel autoinflammatory syndrome named NASA has been identified, characterized by neuroinflammation, systemic autoinflammation, splenomegaly, and anemia, caused by bi-allelic mutations in the IRAK-4 gene.
  • Five patients from two families exhibited severe symptoms including massive splenomegaly and anemia, with some also experiencing neuroinflammation and seizures, linked to specific IRAK-4 mutations affecting its catalytic and regulatory domains.
  • Immunological findings revealed elevated pro-inflammatory cytokines in both serum and cerebrospinal fluid, suggesting that dysfunction in IRAK-4 leads to uncontrolled inflammation despite changes in immune signaling pathways.

There is an important unmet clinical need for fast turnaround next generation sequencing (NGS) to aid genetic diagnosis of patients with acute and sometimes catastrophic inflammatory presentations. This is imperative for patients who require precise and targeted treatment to prevent irreparable organ damage or even death. Acute and severe hyper- inflammation may be caused by primary immunodeficiency (PID) with immune dysregulation, or more typical autoinflammatory diseases in the absence of obvious immunodeficiency.

Deficiency of adenosine deaminase type 2 (DADA2) is an autosomal recessive disease caused by bi-allelic loss-of-function mutations in . Treatment with anti-TNF is effective for the autoinflammatory and vasculitic components of the disease but does not correct marrow failure or immunodeficiency; and anti-drug antibodies cause loss of efficacy over time. Allogeneic haematopoietic stem cell transplantation may be curative, but graft versus host disease remains a significant concern.

Background: This paper describes barriers to engagement in the context of group activities attended by nursing home residents with dementia.

Objective: The goal is to clarify the presence and types of barriers to group activities for persons with dementia.

Methods: Therapeutic recreation staff (TRs) who conducted the group activities, and trained research observers (ROs) independently identified barriers occurring during group activity sessions through ratings and open-ended comments, which were analyzed via a mixed-method approach.

Background: Myhre syndrome is a genetic disorder caused by gain of function mutations in the SMAD Family Member 4 (SMAD4) gene, resulting in progressive, proliferative skin and organ fibrosis. Skin thickening and joint contractures are often the main presenting features of the disease and may be mistaken for juvenile scleroderma.

Case Presentation: We report a case of a 13 year-old female presenting with widespread skin thickening and joint contractures from infancy.

Objective: To report a series of patients with cerebral arteriopathy associated with heterozygous variants in the casitas B-lineage lymphoma () gene and examine the functional role of the identified mutant Cbl protein. We hypothesized that mutated Cbl fails to act as a negative regulator of the RAS-mitogen-activated protein kinases (MAPK) signaling pathway, resulting in enhanced vascular fibroblast proliferation and migration and enhanced angiogenesis and collateral vessel formation.

Methods: We performed whole-exome sequencing in 11 separate families referred to Great Ormond Street Hospital, London, with suspected genetic cause for clinical presentation with severe progressive cerebral arteriopathy.

Objectives: To describe social engagement care (SEC) provided by live-in migrant caregivers for frail older adults compared with care recipients' and families' wishes for such care.

Method: Interviews with care recipients, family members, and migrant caregivers assessed preferences for and provision of five types of SEC activities: knowing the older person as a person, knowing their main concerns, having personal conversations, going for walks, and sharing social or leisure activities.

Results: Care recipients and family proxies reported a moderate desire for SEC from migrant caregivers, except for sharing leisure activities, for which there was only a slight preference.

The Sources of Discomfort Scale (SODS) assesses discomfort manifestations based on source of discomfort, thus making it both distinct from and complementary to pain assessments for persons with dementia. Sources were categorized as pertaining to physical discomfort, to body position, and to environmental sources. Body position sources of discomfort were related to poor functional status and to pain.

Transplant recipients on calcineurin inhibitors are at high risk of invasive fungal infection. Understanding how calcineurin inhibitors impair fungal immunity is a key priority for defining risk of infection. Here, we show that the calcineurin inhibitor tacrolimus impairs clearance of the major mould pathogen Aspergillus fumigatus from the airway, by inhibiting macrophage inflammatory responses.

Background: Affect, behavior, and cognition can be considered as basic constructs that dictate human functioning, with intricate and bi-directional relationships among them. Prior to the present study, relationships among these constructs have not been systematically examined within the context of dementia.

Methods: Sample 1 contained 185 nursing home residents with a diagnosis of dementia.

Purpose Of The Study: Behavior problems are common in nursing homes. Current guidelines recommend nonpharmacological interventions (NPHIs) as first-line treatment, but pharmacological regimens (PIs) continue to be used. Given differences in background and training of those who treat behavior problems in residents, we compared attitudes of physicians (MDs), psychologists (PhDs), and nurse practitioners (NPs) concerning PI and NPHI usage as well as knowledge of NPHIs.

Examination of the relationship between performance testing and psychological measures before and after a 12-week strength and conditioning program was the study's purpose. Female NCAA Division-III soccer (n = 28), field hockey (n = 28), and softball (n = 19) athletes completed pre- and post-testing held 12 weeks apart. On day 1, athletes completed informed consent, 3 psychological measures (Profile of Mood States [POMS], Physical Self Perception Profile [PSPP], and Athlete's Self Perception of Physical Abilities [ASPPA]), and 2 strength tests (1 repetition maximum [1RM] bench, 1RM back squat).

This study investigated eating-related habits and their importance in older people and compared those living in private residences with those in senior retirement community housing. A convenience sample of 58 seniors answered eating-related items from the Self-maintenance Habits and Preferences in Elderly questionnaire (SHAPE). Meal location, companions, concurrent activities, portion size, and food variety differed between private and retirement housing for some meals, but the overall importance assigned to eating practices was similar.
