The application of artificial intelligence to accelerate G protein-coupled receptor drug discovery.

The application of artificial intelligence (AI) approaches to drug discovery for G protein-coupled receptors (GPCRs) is a rapidly expanding area. Artificial intelligence can be used at multiple stages during the drug discovery process, from aiding our understanding of the fundamental actions of GPCRs to the discovery of new ligand-GPCR interactions or the prediction of clinical responses. Here, we provide an overview of the concepts behind artificial intelligence, including the subfields of machine learning and deep learning.

Efficacy and accuracy of faecal sampling by a digital rectal examination for faecal immunochemical testing.

Aim: A digital rectal examination (DRE) during routine assessment for patients with abdominal symptoms provides an opportunity to obtain faeces from the glove for faecal immunochemical testing (FIT). Here, we compared sampling via DRE to the standard faecal sampling by patients.

Method: Patients were recruited to a prospective observational cohort study between July 2019 and March 2020.

Replicate and repeat faecal immunochemical tests in symptomatic patients: A systematic review.

Background: Faecal Immunochemical tests (FITs) in the assessment of patients presenting with symptoms have generally used a single sample. Little evidence pertains to the use of replicate, where a number of tests are done prior to decision-making or repeat FIT, where additional FIT are performed following clinical decision-making. Overwhelmingly, research has focussed on FIT to help identify colorectal cancer (CRC).

Comparison of the QuikRead go point-of-care faecal immunochemical test for haemoglobin with the FOB Gold Wide laboratory analyser to diagnose colorectal cancer in symptomatic patients.

Objectives: Faecal immunochemical testing for haemoglobin (FIT) is used to triage patients for colonic investigations. Point-of-care (POC) FIT devices on the market have limited data for their diagnostic accuracy for colorectal cancer (CRC). Here, a POC FIT device is compared with a laboratory-based FIT system using patient collected samples from the urgent referral pathway for suspected CRC.

Determinants of Shielding Behavior During the COVID-19 Pandemic and Associations With Well-being Among National Health Service Patients: Longitudinal Observational Study.

Background: The UK National Health Service (NHS) classified 2.2 million people as clinically extremely vulnerable (CEV) during the first wave of the 2020 COVID-19 pandemic, advising them to "shield" (to not leave home for any reason).

Objective: The aim of this study was to measure the determinants of shielding behavior and associations with well-being in a large NHS patient population for informing future health policy.

Diagnostic accuracy of point of care faecal immunochemical testing using a portable high-speed quantitative analyser for diagnosis in 2-week wait patients.

Aim: Laboratory-based faecal immunochemical testing (FIT) is the gold standard for detecting the presence of blood in the stool. The aim was to perform a diagnostic accuracy study to confirm if a point of care (POC) analyser for FIT could be safely used as an adjunct in the triage and management of 2-week wait (TWW) colorectal patients.

Methods: The Point of Care Faecal Immunochemical Testing (POC FIT) prospective observational cohort study was designed for TWW patients at a regional referral centre.

Assessment of the analytical performance of point-of-care faecal immunochemical tests for haemoglobin.

Background: The faecal immunochemical test (FIT) detects the presence of haemoglobin (Hb) in faeces. It is used as a screening tool for colorectal cancer (CRC) and increasingly to triage patients presenting with symptoms of CRC. A number of quantitative point-of-care (POC) FIT systems marketed for professional use and intended for use in a clinical setting are available.

Adoption of faecal immunochemical testing for 2-week-wait colorectal patients during the COVID-19 pandemic: an observational cohort study reporting a new service at a regional centre.

Aim: The COVID-19 pandemic has resulted in the near-complete loss of routine endoscopy services. We describe a major reorganization of service at a regional referral centre (Royal Surrey NHS Foundation Trust) to manage the crisis. Faecal immunochemical testing (FIT) was implemented for triage to make optimum use of limited diagnostic resources.

"My Voice Counts, Too": Voting Participation Among Individuals With Intellectual Disability.

Despite a strong societal commitment to ensuring that individuals with intellectual disability (ID) fully participate in their communities, few people with ID vote. Little is known about voting experiences from the perspective of people with ID. In-person, semistructured interviews were conducted with 28 adults with ID (Mage = 37 years) to obtain their input on voting.

A Direct Comparison of Self-Injurious and Stereotyped Motor Behavior Between Preschool-Aged Children With and Without Developmental Delays.

Objective: To compare the prevalence of self-injurious behavior (SIB) and stereotyped motor behavior (STY) of preschool-aged children with developmental delays (DD group) and their peers without developmental delays (TD group) using a standardized caregiver report scale.

Methods: The Repetitive Behavior Scale-Revised was completed by caregivers of children with developmental delays and their peers without developmental delays. Frequency of occurrence and severity ratings for SIB and STY were compared between groups.

A practical approach to classifying and managing feeding difficulties.

Many young children are thought by their parents to eat poorly. Although the majority of these children are mildly affected, a small percentage have a serious feeding disorder. Nevertheless, even mildly affected children whose anxious parents adopt inappropriate feeding practices may experience consequences.

Large gallstone impaction at a Meckel's diverticulum causing perforation and localized peritonitis: report of a case.

We are reporting a successful laparoscopic resection of a perforated Meckel's Diverticulum (MD) causing localized peritonitis due to an impacted gallstone. MD is a small benign pouch on the wall of the small intestine that is present in ∼2% of the population. It results from a failure of complete obliteration of the omphalomesenteric duct.

Assessment of the prerequisite skills for cognitive behavioral therapy in children with and without autism spectrum disorders.

The purpose of this study was to assess the cognitive skills of children with autism spectrum disorders (ASD) thought to be necessary for Cognitive Behavioral Therapy (CBT). Forty children with ASD and forty age-matched typically developing children between the ages of 7-12 years participated. Groups were comparable with regard to nonverbal IQ, but children with ASD had significantly lower verbal IQ.

Self-injury among a community cohort of young children at risk for intellectual and developmental disabilities.

Objective: To identify risk factors for self-injurious behavior in young children with developmental delay and to determine whether that group is also more likely to exhibit other challenging behaviors.

Study Design: A retrospective chart review of 196 children < 6 years of age referred for comprehensive neurodevelopmental evaluations. We analyzed child developmental level, receptive and expressive communication level, mobility, visual and auditory impairment, and co-morbid diagnoses of cerebral palsy, seizure disorders, and autism.

Stressful social interactions experienced by adults with mild intellectual disability.

Adults with intellectual disability are vulnerable to stressful social interactions. We determined frequency and severity of various stressful social interactions, identified the social partners in these interactions, and examined the specific interpersonal skill difficulties of 114 adults with mild intellectual disability. Participants' characteristic risk factors for stressful social interactions were also identified.

Depression in adults with mild intellectual disability: role of stress, attributions, and coping.

The experience of stressful social interactions, negative causal attributions, and the use of maladaptive coping efforts help maintain depression over time in the general population. We investigated whether a similar experience occurs among adults with mild intellectual disability. We compared the frequency and stress impact of such interactions, identified causal attributions for these interactions, and determined the coping strategies of 47 depressed and 47 nondepressed adults with mild intellectual disability matched on subject characteristics.

Coping Strategies of Adults with Mild Intellectual Disability for Stressful Social Interactions.

Adults with mild intellectual disability (ID) experience stressful social interactions and often utilize maladaptive coping strategies to manage these interactions. We investigated the specific types of Active and Avoidant coping strategies reported by 114 adults with mild ID to deal with stressful social interactions. Open-ended responses to a sentence stem task were coded into five dimensions of Active and Avoidant coping.

Patient and parent/guardian perspectives on the health care of adults with mental retardation.

Individuals with mental retardation and their parents/guardians have long been neglected in health care research. In this study we used a qualitative methodology to describe the experiences adults with mental retardation and their parents/guardians have with the delivery of primary care services. Semi-structured in-depth interviews were conducted with 12 adults who had mental retardation and 9 parents/guardians.

Spontaneous eye-blinking and stereotyped behavior in older persons with mental retardation.

Previous research indicates that abnormal stereotyped movements are associated with central dopamine dysfunction and that eye-blink rate is a noninvasive, in vivo measure of dopamine function. We measured the spontaneous eye-blinking and stereotyped behavior of older adults with severe/profound mental retardation living in a state mental retardation facility. Analyses revealed that the mean eye-blink rate of the residents that engaged in stereotypy was significantly lower than the rate for residents who did not exhibit stereotypy.

Perceptions of stress and coping strategies among adults with mild mental retardation: insight into psychological distress.

Stress, coping, perceptions of control, and psychological distress of 88 adults with mild mental retardation were assessed. Stressful interpersonal interactions and concerns over personal competencies occurred most frequently. Frequency and stress impact were positively associated with a composite score of psychological distress.

Maladaptive behaviors and risk factors among the genetic subtypes of Prader-Willi syndrome.

Maladaptive behaviors among 65 people with Prader-Willi syndrome were assessed using the Reiss Screen for maladaptive behaviors. Young adults in their twenties were more likely to display aggressive behavior than adolescents and older adults. Differences in maladaptive behaviors between the typical deletion and uniparental disomy (UPD) subtypes were evaluated.

Innovation in infant formula development: a reassessment of ribonucleotides in 2002.

Nucleotides play a significant role in many physiologic functions, ranging from the encoding of genetic information to signal transduction. Accumulating evidence from recent animal and clinical studies supports the original notion that nucleotides are semi-essential dietary nutrients. The development of a new technique, total potentially available nucleosides, to accurately quantify the nucleotide content in various biological fluids has allowed investigators to properly assess the importance of nucleotide function and availability in various conditions.
