Article Synopsis
  • - The study explores the long-term effects of SARS-CoV-2 in children and young people (CYP), identifying a condition called post-COVID-19 condition (PCC) and examining symptoms and impacts up to 24 months post-infection.
  • - Out of 31,012 eligible CYP, 12,632 participated, revealing that 7.2% consistently met the PCC criteria over two years, with around 20-25% reporting three or more symptoms, and symptom severity was found to be higher in older and more deprived groups.
  • - The findings emphasize the necessity of longitudinal research to better understand both the prevalence and severity of PCC symptoms in CYP, as well as the importance of monitoring clinical impairment over

Background: Post-COVID Condition (PCC), also known as 'Long COVID,' refers to persistent symptoms following a coronavirus 2 (SARS-CoV-2) infection. The prevalence of PCC in children and adolescents varies, impacting multiple body systems and affecting daily functioning. Specialised paediatric hubs were established in England to address the needs of young individuals with PCC.

Article Synopsis
  • Cognitive impairment, referred to as "brain fog," was reported in 7.0% of first-time PCR-positive children and young people (CYP) and 7.5% of reinfected CYP 12 months after SARS-CoV-2 infection, indicating no significant difference by infection status.
  • Most cases of cognitive impairment either appeared at the time of testing or within three months post-test, with similar prevalence observed across both groups.
  • A majority of those with cognitive issues were aged 15 to 17, suggesting a potential age-related trend in the manifestation of cognitive impairments related to the infection.

The coronavirus disease 2019 (COVID-19) pandemic substantially impacted different age groups, with children and young people not exempted. Many have experienced enduring health consequences. Presently, there is no consensus on the health outcomes to assess in children and young people with post-COVID-19 condition.

Background: Post-COVID services have been set up in England to treat children with ongoing symptoms of Long COVID. To date, the characteristics of children seeking treatment from these services has not been described.

Purpose: (1) to describe the characteristics of children aged 11-17 referred to the Pan-London Post-COVID service and (2) to compare characteristics of these children with those taking part in the United Kingdom's largest research study of Long COVID in children (CLoCk).

Article Synopsis
  • The study investigates the impact of the COVID-19 pandemic on loneliness among children and young people (CYP), noting an increase from 6.5% feeling lonely before the pandemic to 17.4% during it.
  • A total of 31,017 participants from the Children with Long COVID (CLoCk) study completed an online survey addressing loneliness in relation to demographics, lifestyle, and health.
  • Results show significant associations between loneliness and factors such as age, gender, ethnicity, family size, and socioeconomic status, highlighting the need for targeted interventions and ongoing support for affected CYP.

Background: The onset of type 2 diabetes (T2D) is increasingly common in adolescents and young adults (AYAs). Improving self-management skills and the mental health of this population is important, but understudied.

Methods: The goal of this research was to develop a mind-body intervention which could serve as an adjunctive therapy to support AYAs with T2D (INTEND intervention).

Background: Although 99% of children and young people have been exposed to SARS-CoV-2, the long-term prevalence of post-COVID-19 symptoms in young people is unclear. The aim of this study is to describe symptom profiles 12 months after SARS-CoV-2 testing.

Method: A matched cohort study of a national sample of 20,202 children and young people who took a SARS-CoV-2 PCR test between September 2020 and March 2021.

To describe the prevalence of long COVID in children infected for the first time (n = 332) or reinfected (n = 243) with Omicron compared with test-negative children (n = 311). Overall, 12%-16% of those infected with Omicron met the research definition of long COVID at 3 and 6 months after infection, with no evidence of difference between cases of first positive and reinfected (P = 0.17).

Functional neurological disorder (FND) can be a difficult diagnosis for patients to understand and for clinicians to explain. The postdiagnostic support that patients with other chronic neurological illnesses normally receive is often not available to patients with FND. Here, we share our experience of how to set up an FND education group, including the content, practical aspects of delivering groups and how to avoid potential pitfalls.

Post-COVID-19 syndrome is a new condition that can have a major impact on the physical and mental well-being of children and young people, affecting their ability to access activities including education. Paediatricians and general practitioners need to be able to assess and manage patients with this condition; making the diagnosis, excluding serious pathology, managing comorbidities and accessing appropriate management are crucial. This 15 minute consultation presents an approach to history taking, examination, investigations, management principles and referrals.

Objectives: Primary objective: to determine the point prevalence and incidence rate of severe myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) in children aged 5-16 years over 13 months.

Secondary Objectives: to describe the demographic features, symptoms, impact on activities of daily living, school attendance and time to diagnosis.

Design: Prospective surveillance study conducted by the British Paediatric Surveillance Unit.

Purpose Of The Study: There is limited published data on treatment or outcomes of children and young people (CYP) with moderate or severe Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Here, we describe outcomes of moderate and severe ME/CFS in CYP treated in a tertiary adolescent service. This information is useful when planning services for CYP and families affected by moderate/severe ME/CFS and to guide future management trials and commissioning decisions.

Climate change is a major risk factor for overall health, including reproductive health, and well-being. Increasing temperatures, due mostly to increased greenhouse gases trapping excess heat in the atmosphere, result in erratic weather patterns, wildfires, displacement of large communities, and stagnant water resulting in vector-borne diseases that, together, have set the stage for new and devastating health threats across the globe. These conditions disproportionately affect disadvantaged and vulnerable populations, including women, pregnant persons, young children, the elderly, and the disabled.

Introduction: The destination of transgender and gender variant young people referred by the National Health Service (NHS) Gender Identity Development Service (GIDS) to, and discharged from the two English paediatric endocrine liaison clinics is not known.

Methods: 1151 young people referred after full assessment by the GIDS; 827 to University College London Hospital since 2008; 324 to Leeds Children's Hospital since 2013. Discharge categorisation was by agreed criteria.

There is an observed link between physical illness and mental health difficulties and an increased likelihood of mental health difficulties in young people with chronic health conditions. The main outcome focus in paediatric settings is on physical health outcomes and functioning. In terms of functioning, the focus is on quality of life, measures of emotional well-being and perceptions of personal change, which are likely to be multifaceted and vary between patients.

More than one third of the mammalian genome is in a close association with the nuclear lamina, thus these genomic regions were termed lamina-associated domains (LADs). This association is fundamental for many aspects of chromatin biology including transcription, replication, and DNA damage repair. LADs association with the nuclear envelope is thought to be dependent on two major mechanisms: The first mechanism is the interaction between nuclear membrane proteins such as LBR with heterochromatin modifications that are enriched in LADs chromatin.

Gonadotropin-releasing hormone agonists (GnRHa) are used as an alternative to human chorionic gonadotropin (hCG) to trigger ovulation and decrease the risk of ovarian hyperstimulation syndrome. GnRHa is less potent at inducing ovarian vascular endothelial growth factor (VEGF), but may also affect endometrial angiogenesis and early placental development. In this study, we explore the effect of superovulation on endometrial angiogenesis during critical periods of gestation in a mouse model.
