A Systematic Review and Bayesian Network Meta-Analysis Investigating the Effectiveness of Psychological Short-Term Interventions in Inpatient Palliative Care Settings.

This paper reviews and summarises the evidence of short-term psychosocial interventions (up to 12 sessions delivered within less than eight weeks) on anxiety, depression, and emotional distress in palliative patients in inpatient settings. We screened publications from the following five databases, Embase, PubMed, PsycINFO, Web of Science, and CINAHL, from their inception to 10 September 2021. The eligible studies included controls receiving standard palliative care, actively treated controls, and wait-list controls.

Organizational determinants of information transfer in palliative care teams: A structural equation modeling approach.

Several organizational factors facilitate or hinder information transfer in palliative care teams. According to past research, organizational factors that reduce information transfer include the inconsistent use of shared electronic patient files, frequent changes of healthcare staff, a lack of opportunities for personal exchange, and a lack of evaluation of collaborative processes. Insufficient information sharing between professionals can negatively impact patient safety, whereas studies have shown that some organizational factors improve collaboration between professionals and thus contribute to improved patient outcomes.

Recommendations for live viral and bacterial vaccines in immunodeficient patients and their close contacts.

The present uncertainty of which live viral or bacterial vaccines can be given to immunodeficient patients and the growing neglect of societal adherence to routine immunizations has prompted the Medical Advisory Committee of the Immune Deficiency Foundation to issue recommendations based on published literature and the collective experience of the committee members. These recommendations address the concern for immunodeficient patients acquiring infections from healthy subjects who have not been immunized or who are shedding live vaccine-derived viral or bacterial organisms. Such transmission of infectious agents can occur within the hospital, clinic, or home or at any public gathering.

Gene therapy for adenosine deaminase-deficient severe combined immune deficiency: clinical comparison of retroviral vectors and treatment plans.

We conducted a gene therapy trial in 10 patients with adenosine deaminase (ADA)-deficient severe combined immunodeficiency using 2 slightly different retroviral vectors for the transduction of patients' bone marrow CD34(+) cells. Four subjects were treated without pretransplantation cytoreduction and remained on ADA enzyme-replacement therapy (ERT) throughout the procedure. Only transient (months), low-level (< 0.

Somatic mosaicism in the Wiskott-Aldrich syndrome: molecular and functional characterization of genotypic revertants.

The reasons underlying the occurrence of multiple revertant genotypes in Wiskott-Aldrich syndrome (WAS) patients remain unclear. We have identified more than 30 revertant genotypes in a C995T WAS patient having 10-15% revertant, WAS protein (WASp)-expressing circulating lymphocytes. Of 497 allospecific T-cell clones generated from the peripheral blood, 47.

What is the status of gene therapy for primary immunodeficiency?

The efforts to find satisfactory treatments for seriously ill patients with primary immunodeficiency have resulted in the development of important new therapeutic procedures with benefits reaching far beyond the relatively small number of patients affected with these rare disorders. Allogeneic bone marrow transplantation, immunoglobulin and enzyme replacement treatments and more recently gene therapy have all been introduced into clinical medicine as treatments for one or more of the primary immunodeficiency diseases. Beginning in 1990, gene-corrected T cells were first used to treat ADA deficiency SCID.

Preferential survival of CD4+ T lymphocytes engineered with anti-human immunodeficiency virus (HIV) genes in HIV-infected individuals.

The present study examined the safety and relative in vivo survival of genetically engineered CD4+ T lymphocytes in human immunodeficiency virus (HIV)-infected individuals. Ten pairs of identical twins discordant for HIV infection were recruited, with the uninfected twin serving as the lymphocyte donor. Ten subjects were treated with a total of 19 separate infusions of retroviral vector-transduced CD4+ enriched T cells.

Induction of an antitumor immunological response by an intratumoral injection of dendritic cells pulsed with genetically engineered Semliki Forest virus to produce interleukin-18 combined with the systemic administration of interleukin-12.

Object: The aim of this study was to investigate further immunogene treatment of malignant brain tumor to improve its therapeutic efficacy.

Methods: Intratumoral dendritic cells pulsed with Semliki Forest virus (SFV)-interleukin-18 (IL-18) and/or systemic IL-12 were injected into mice bearing the B16 brain tumor. To study the immune mechanisms involved in tumor regression, we monitored the growth of implanted B16 brain tumor cells in T cell-depleted mice and IFNgamma-neutralized mice.

Persistence and expression of the adenosine deaminase gene for 12 years and immune reaction to gene transfer components: long-term results of the first clinical gene therapy trial.

The first human gene therapy experiment begun in September 1990 used a retroviral vector containing the human adenosine deaminase (ADA) cDNA to transduce mature peripheral blood lymphocytes from patients with ADA deficiency, an inherited disorder of immunity. Two patients who had been treated with intramuscular injections of pegylated bovine ADA (PEG-ADA) for 2 to 4 years were enrolled in this trial and each received a total of approximately 10(11) cells in 11 or 12 infusions over a period of about 2 years. No adverse events were observed.

Immune response to fetal calf serum by two adenosine deaminase-deficient patients after T cell gene therapy.

The first approved clinical gene therapy trial for adenosine deaminase (ADA) deficiency employed autologous T cells grown in fetal calf serum (FCS)-supplemented medium and transduced with a retroviral vector (LASN) also produced in the presence of FCS. Ten years after their enrollment, both patients have circulating T cells containing vector DNA. However, whereas approximately 20% of the circulating T cells from patient 1 are still vector positive, less than 1% of patient 2's T cells have detectable vector.

The release of inflammatory cytokines from human peripheral blood mononuclear cells in vitro following exposure to adenovirus variants and capsid.

Preclinical and clinical studies with adenoviral vectors have clearly illustrated the potential advantages of this gene transfer system. However, many studies have also demonstrated potent immune responses directed at both vector and transduced cells. We examined in vitro responses of human peripheral blood mononuclear cells (PBMC) to virus exposure as a model for this host response.

Biosynthetic ganciclovir triphosphate: its isolation and characterization from ganciclovir-treated herpes simplex thymidine kinase-transduced murine cells.

A method is described for the preparation of ganciclovir triphosphate (GCV-TP) using murine colon cancer cells (MC38) transduced with the herpes simplex virus-thymidine kinase (MC38/HSV-tk). Murine cells transduced with viral-tk contain required viral and host enzymes needed for complete cellular synthesis of this potent antiviral metabolite. Dose response studies showed optimal intracellular levels of GCV-TP occurred after exposure of MC38/HSV-tk cells to 300 microM ganciclovir for 24 h producing 7.

AV.TK-mediated killing of subcutaneous tumors in situ results in effective immunization against established secondary intracranial tumor deposits.

Gene transfer vectors expressing herpes simplex thymidine kinase (HSVtk), in addition to direct killing of tumor cells, often have an associated local "bystander effect" mediated by metabolic coupling of tumor cells. A systemic antitumor effect mediated by the immune system, termed the distant bystander effect, has also been reported. We have observed the development of cytotoxic T-lymphocyte (CTL) populations and long-lasting antitumor immunity following treatment of subcutaneous tumors with an adenoviral vector expressing HSVtk (AV.

Development of a skin-based metabolic sink for phenylalanine by overexpression of phenylalanine hydroxylase and GTP cyclohydrolase in primary human keratinocytes.

Phenylketonuria, PKU, is caused by deficiency of phenylalanine hydroxylase (PAH) resulting in increased levels of phenylalanine in body fluids. PAH requires the non-protein cofactor BH4 and the rate-limiting step in the synthesis of BH4 is GTP cyclohydrolase I (GTP-CH). Here we show that overexpression of the two enzymes PAH and GTP-CH in primary human keratinocytes leads to high levels of phenylalanine clearance without BH4 supplementation.

Long-term in vivo survival of receptor-modified syngeneic T cells in patients with human immunodeficiency virus infection.

To study human immunodeficiency virus (HIV)-specific cellular immunity in vivo, we transferred syngeneic lymphocytes after ex vivo expansion and transduction with a chimeric receptor gene (CD4/CD3-zeta) between identical twins discordant for HIV infection. Single and multiple infusions of 10(10) genetically modified CD8(+) T cells resulted in peak fractions in the circulation of approximately 10(4) to 10(5) modified cells/10(6) mononuclear cells at 24 to 48 hours, followed by 2- to 3-log declines by 8 weeks. In an effort to provide longer high-level persistence of the transferred cells and possibly enhance anti-HIV activity, we administered a second series of infusions in which both CD4(+ )and CD8(+) T cells were engineered to express the chimeric receptor and were costimulated ex vivo with beads coated with anti-CD3 and anti-CD28.
