INT-1B3, an LNP formulated miR-193a-3p mimic, promotes anti-tumor immunity by enhancing T cell mediated immune responses via modulation of the tumor microenvironment and induction of immunogenic cell death.

microRNAs (miRNAs) are small, non-coding RNAs that regulate expression of multiple genes. MiR-193a-3p functions as a tumor suppressor in many cancer types, but its effect on inducing specific anti-tumor immune responses is unclear. Therefore, we examined the effect of our lipid nanoparticle (LNP) formulated, chemically modified, synthetic miR-193a-3p mimic (INT-1B3) on anti-tumor immunity.

The potential unintended consequences of Mental Health Act reforms in England and Wales on people with intellectual disability and/or autism.

The draft Mental Health Bill, which amends the Mental Health Act 1983 for England and Wales, proposes protections for people with intellectual disability and/or autism (ID/A) to prevent detention in hospital in the absence of mental illness. This editorial critically appraises the positive impact and unintended consequences of the proposed reforms for people with ID/A.

The use of medical care and the prevalence of serious illness in an adult Prader-Willi syndrome cohort.

Introduction: Adults with Prader-Willi syndrome (PWS) have an increased occurrence of several medical conditions. We report on the consequences of high morbidity rates such as prevalence rate of hospital admissions, medication use and surgery in a Dutch cohort of adults with PWS. Special attention is paid to causes and symptoms of serious illness.

Aging in Prader-Willi syndrome: twelve persons over the age of 50 years.

The life expectancy of persons with Prader-Willi syndrome (PWS) has increased in recent years. Because of the paucity of reports on older persons with PWS, the natural history, the onset, and type of age-related problems are poorly understood. Twelve persons with a genetically confirmed diagnosis of PWS aged over 50 years are described (4 deletion; 8 mUPD).

What's in a name? - The Psychiatric Identity Conundrum.

Background: The proper label to describe people receiving care has evoked considerable debate and controversy among providers and bio-ethicists. Fashionable terms in current use include "patient, client, consumer, customer and service user." There is little evidence to show that changes in nomenclature actually take patients preferences as to how they would like to be addressed into account

Aims: This aim of this study is to survey the views of the people with learning disability in inpatient settings to establish the term they prefer.

Psychiatric illness in a cohort of adults with Prader-Willi syndrome.

Previous studies have suggested an association between PWS and comorbid psychiatric illness. Data on prevalence rates of psychopathology is still scarce. This paper describes a large-scale, systematic study investigating the prevalence of psychiatric illness in a Dutch adult PWS cohort.

Behavioral phenotype in adults with Prader-Willi syndrome.

Prader-Willi syndrome (PWS) is characterized by temper tantrums, impulsivity, mood fluctuations, difficulty with change in routine, skinpicking, stubbornness and aggression. Many studies on behavior in PWS are limited by sample size, age range, a lack of genetically confirmed diagnosis of PWS and inconsistent assessment of behavior. The aim of this study was to explore systematically the relation between behavioral problems and age groups, genetic subtypes and BMI categories in an adult PWS population.

In search of the psychosis gene in people with Prader-Willi syndrome.

The two main causes of Prader-Willi syndrome (PWS) are a paternally derived deletion in the maternally imprinted 15q11-q13 region or UPD(15)mat. Both mechanisms result in a loss of the active paternal contribution to the region. The affective psychosis associated with PWS has been found to be mainly confined to the propositi with UPD(15)mat rather than to those with a deletion.

Analysis of candidate imprinted genes in PWS subjects with atypical genetics: a possible inactivating mutation in the SNURF/SNRPN minimal promoter.

Prader-Willi syndrome (PWS) is a neurodevelopmental disorder associated with abnormalities of chromosome 15q11q13. The majority of cases result either from a deletion approximately 4 Mb in size, affecting chromosome 15 of paternal origin or from UPD(15)mat; these account for approximately 70 and approximately 20-25% of PWS cases, respectively. In the remaining 3-5% of PWS cases where neither the deletion nor UPD is detectable, PWS is thought to be caused either by a defect in the imprinting centre resulting in a failure to reset the paternally inherited chromosome 15 derived from the paternal grandmother or, very occasionally, from a balanced translocation involving a breakpoint in 15q11q13.

Differences in behavioural phenotype between parental deletion and maternal uniparental disomy in Prader-Willi syndrome: an ERP study.

Objective: Paternal deletion and maternal uniparental disomy are the principal genetic subtypes associated with Prader-Willi syndrome (PWS). Recent clinical findings suggest differences in phenotype between these subtypes. The present experimental study addresses this issue using a cognitive psycho-physiological setup.

Psychotic illness in people with Prader Willi syndrome due to chromosome 15 maternal uniparental disomy.

In a population-based study of Prader Willi syndrome (PWS), we investigated the relation between genetic subtypes of the syndrome and psychiatric morbidity. Of 25 patients aged 18 years or older, seven (28%) had severe affective disorder with psychotic features, with a mean age of onset of 26 years (SD 5.9).
