Association between home working and mental health by key worker status during the Covid-19 pandemic. Evidence from four British longitudinal studies.

Ind Health 2022 May 19. Epub 2022 May 19.

MRC Unit for Lifelong Health and Ageing, University College London, United Kingdom.

Little is known about the relationship between homeworking and mental health during the Covid-19 pandemic and how it might differ by keyworker status. To understand this relationship, we use longitudinal data collected over three time points during the pandemic from three British cohort studies born in 1958 (National Child Development Study), 1970 (British Cohort Study) and 1989-90 (Next Step) as well as from a population-based study stratified by four age groups (Understanding Society). We estimate the association between life satisfaction, anxiety, depression, and psychological distress and homeworking by key worker status using mixed effects models with maximum likelihood estimation to account for repeated measurements across the pandemic, allowing intercepts to vary across individuals after controlling for a set of covariates including pre-pandemic home working propensities and loneliness.

Determining Vascular Risk Factors for Dementia and Dementia Risk Prediction Across Mid- to Later-Life: The Framingham Heart Study.

Neurology 2022 May 18. Epub 2022 May 18.

The Framingham Heart Study, Framingham, MA, USA.

Background And Objectives: The association between vascular risk factors and dementia varies with age making generalisability of dementia risk prediction rules to individuals of different ages challenging. We determined the most important vascular risk factors for inclusion in age-specific dementia risk scores.

Methods: Framingham Heart Study Original and Offspring cohort participants with available data on the Framingham Stroke Risk Profile (FSRP) at mid-life(age 55; n=4899, 57% women), late-life(ages 65 or 70), or later-life(ages 75 or 80[n=2386, 62% women]) were followed for 10-year incident dementia risk from ages 65, 70, 75 and 80.

Sensitivity of the Social Behavior Observer Checklist to Early Symptoms of Patients With Frontotemporal Dementia.

Neurology 2022 May 18. Epub 2022 May 18.

Department of Neurology, Memory and Aging Center, University of California, San Francisco, San Francisco, CA, USA.

Background And Objectives: Changes in social behavior are common symptoms of frontotemporal lobar degeneration (FTLD) and Alzheimer's disease syndromes. For early identification of individual patients and differential diagnosis, sensitive clinical measures are required that are able to assess patterns of behaviors and detect syndromic differences in both asymptomatic and symptomatic stages. We investigated whether the examiner-based Social Behavior Observer Checklist (SBOCL) is sensitive to early behavior changes and reflects disease severity within and between neurodegenerative syndromes.

Risk-adapted chemoimmunotherapy using brentuximab vedotin and rituximab in children, adolescents, and young adults with newly diagnosed Hodgkin's lymphoma: a phase II, non-randomized controlled trial.

J Immunother Cancer 2022 May;10(5)

Pediatrics, New York Medical College, Valhalla, New York, USA

Background: Cure rates for Hodgkin's lymphoma are excellent, but excess short-term and long-term morbidities from treatment remain a concern. Immunotherapy targeting both tumor antigens and the immunosuppressive tumor microenvironment in children, adolescents, and young adults with Hodgkin's lymphoma may improve early response rates and eliminate toxic chemotherapy and radiation, thus minimizing toxicity. We conducted a phase II study to evaluate the safety and overall response rate of brentuximab vedotin and rituximab in combination with risk-adapted chemotherapy in children, adolescents, and young adults with newly diagnosed classic Hodgkin's lymphoma (cHL).

Minimally invasive pelvic exenteration for gynaecological malignancy: A single-centre case series and review of the literature.

Eur J Obstet Gynecol Reprod Biol 2022 May 11;274:56-61. Epub 2022 May 11.

Academic Department of Gynaecological Oncology, Royal Surrey NHS Foundation Trust, Surrey, UK. Electronic address:

For those with certain recurrent gynaecological cancers where primary management such as chemo-radiotherapy has failed, or in cases of recurrence following primary surgery, pelvic exenteration (PE) is considered the only curative option. Whilst initially considered a morbid procedure, improved surgical techniques, advancing technology, and nuanced reconstructive options have facilitated more radical resections and improved morbidity and mortality. Open PE remains the gold standard approach, however, minimally invasive techniques for PE may lessen morbidity whilst achieving the same oncological outcomes. Read More

Tumor and Constitutional Sequencing for Neurofibromatosis Type 1.

JCO Precis Oncol 2022 May;6:e2100540

Institute for Human Genetics, University of California San Francisco, San Francisco, CA.

Purpose: variants in tumors are important to recognize, as multiple mechanisms may give rise to biallelic variants. Both deletions and copy-neutral loss of heterozygosity (LOH) are potential mechanisms of loss, distinct from point mutations, and additional genes altered may drive different tumor types. This study investigates whether tumors from individuals with neurofibromatosis type 1 (NF1) demonstrate additional gene variants and detects second hits using paired germline and somatic sequencing.
