A meta-analysis of the efficacy of vascularised lymph node transfer in reducing limb volume and cellulitis episodes in patients with cancer treatment-related lymphoedema.

Background: Lymphoedema after cancer treatment is a chronic and disabling complication that presents a significant health care burden during survivorship with limited treatment options. Vascularised lymph node transfer (VLNT) can reconstruct lymphatic flow to reduce limb volumes, but limited higher-order evidence exists to support its effectiveness.

Aim: The aim of the study was to systematically review and meta-analyse the effectiveness of VLNT in reducing upper limb (UL) or lower limb (LL) volume and cellulitis episodes in patients with cancer treatment-related lymphoedema (CTRL).

Psychological resilience early in the COVID-19 pandemic: Stressors, resources, and coping strategies in a national sample of Americans.

Spreading rapidly across the United States beginning in the spring of 2020, the coronavirus disease 2019 (COVID-19) pandemic radically disrupted Americans' lives. Previous studies of community-wide disasters suggested people are fairly resilient and identified resources and strategies that promote that resilience. Yet, the COVID-19 pandemic is in some ways unique, with high levels of uncertainty, evolving implications and restrictions, and varied and uneven impacts.

Community Coalition Efforts to Prevent Adolescent Substance Use: A Systematic Review.

A systematic review explored the creation and maintenance of community coalitions as effective for alcohol and other drug (AOD) prevention in adolescence. Community coalitions influence the implementation of effective and sustainable community-based prevention via infrastructure supporting development, delivery, and assessment of human service issues. For this review, 1,435 articles were identified, most including insufficient detail on the purposes and activities of coalitions or focus on adolescents.

COVID-19 Risk Factors for Cancer Patients: A First Report with Comparator Data from COVID-19 Negative Cancer Patients.

Very few studies investigating COVID-19 in cancer patients have included cancer patients as controls. We aimed to identify factors associated with the risk of testing positive for SARS CoV2 infection in a cohort of cancer patients. We analyzed data from all cancer patients swabbed for COVID-19 between 1 March and 31 July 2020 at Guy's Cancer Centre.

Evaluation of splenic accumulation and colocalization of immature reticulocytes and Plasmodium vivax in asymptomatic malaria: A prospective human splenectomy study.

Background: A very large biomass of intact asexual-stage malaria parasites accumulates in the spleen of asymptomatic human individuals infected with Plasmodium vivax. The mechanisms underlying this intense tropism are not clear. We hypothesised that immature reticulocytes, in which P.

Transthyretin amyloid fibrils alter primary fibroblast structure, function, and inflammatory gene expression.

Age-related wild-type transthyretin amyloidosis (wtATTR) is characterized by systemic deposition of amyloidogenic fibrils of misfolded transthyretin (TTR) in the connective tissue of many organs. In the heart, this leads to cardiac dysfunction, which is a significant cause of age-related heart failure. The hypothesis tested is that TTR affects cardiac fibroblasts in ways that may contribute to fibrosis.

Associations of alcohol, marijuana, and polysubstance use with non-adherence to COVID-19 public health guidelines in a US sample.

We sought to understand the association between heavy alcohol and frequent drug use and non-adherence to recommended social distancing and personal hygiene guidelines for preventing the spread of COVID-19 early in the US pandemic. A survey was offered on the crowdsourcing platform, Amazon Mechanical Turk (MTurk) during April 2020 (the early days of strict, social distancing restrictions). The study included 1,521 adults ages 18 years and older who resided in the US and were enrolled as MTurk workers, i.

Capacity of an ecologically key urchin to recover from extreme events: Physiological impacts of heatwaves and the road to recovery.

Heatwaves are increasing in frequency and intensity, with substantial impacts on ecosystems and species which maintain their function. Whether or not species are harmed by heatwave conditions by being pushed beyond their physiological bounds can depend on whether energy replacement is sufficient to enable recovery from acute stress. We exposed an ecologically important sea urchin, Heliocidaris erythrogramma, to experimental marine heatwave scenarios in context with recent summer heat anomalies in moderate (25 °C), and strong heatwave (26 °C) conditions for 10 days, followed by a 10-day recovery period at normal summer temperature (23 °C).

Determinants of enhanced vulnerability to coronavirus disease 2019 in UK patients with cancer: a European study.

Background: Despite high contagiousness and rapid spread, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to heterogeneous outcomes across affected nations. Within Europe (EU), the United Kingdom (UK) is the most severely affected country, with a death toll in excess of 100,000 as of January 2021. We aimed to compare the national impact of coronavirus disease 2019 (COVID-19) on the risk of death in UK patients with cancer versus those in continental EU.

Association of Age, Antipsychotic Medication, and Symptom Severity in Schizophrenia With Proton Magnetic Resonance Spectroscopy Brain Glutamate Level: A Mega-analysis of Individual Participant-Level Data.

Importance: Proton magnetic resonance spectroscopy (1H-MRS) studies indicate that altered brain glutamatergic function may be associated with the pathophysiology of schizophrenia and the response to antipsychotic treatment. However, the association of altered glutamatergic function with clinical and demographic factors is unclear.

Objective: To assess the associations of age, symptom severity, level of functioning, and antipsychotic treatment with brain glutamatergic metabolites.

Outcomes of head and neck cancer management from two cancer centres in Southern and Northern Europe during the first wave of COVID-19.

Objective: To describe the approach and outcomes from two cancer centres in Southern and Northern Europe during the first wave of coronavirus disease 2019 (COVID-19) of patients with head and neck cancer (HNC).

Methods: Data collection was performed on a retrospective cohort of patients surgically treated for primary HNC between March and May 2020, using data from two tertiary hospitals: the European Institute of Oncology (Milan) and Guy's & St Thomas' NHS Foundation Trust (London).

Results: We included 77 patients with HNC.

The effect of delayed feeding post-hatch on caeca development in broiler chickens.

1. Broiler chicks are frequently deprived of food up to 72 h due to uneven hatching rates, management procedures and transportation to farms. Little is known about the effect of delayed feeding due to extended hatching times on the early neonatal development of the caeca.

Factors determining ultra-short-term survival and the commencement of active treatment in high-grade serous ovarian cancer: a case comparison study.

Background: Despite improvements in median survival some patients with advanced ovarian cancer die within 100 days of diagnosis; the reasons for which remain poorly understood. Here we investigate if ultra short-term survival can be explained by patient characteristics or treatment pathways.

Methods: A nested case comparison study was used to examine differences between patients with high grade serous ovarian/fallopian tube cancer who died within 100 days (n = 28) compared to a comparison group of patients matched for histology and including any survival greater than 100 days (n = 134).

Symptomatic, biochemical and radiographic recovery in patients with COVID-19.

Background: The symptoms, radiography, biochemistry and healthcare utilisation of patients with COVID-19 following discharge from hospital have not been well described.

Methods: Retrospective analysis of 401 adult patients attending a clinic following an index hospital admission or emergency department attendance with COVID-19. Regression models were used to assess the association between characteristics and persistent abnormal chest radiographs or breathlessness.

Perspectives of health care use and access to care for individuals living with inflammatory bowel disease in rural Canada.

Introduction: Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract with no known cure. Management of IBD is complex and requires those with IBD to have lifelong interactions with the healthcare system. Individuals with IBD who live in rural areas are at risk of poorer health outcomes due to their limited access to care.

Continuity of Cancer Care: The Surgical Experience of Two Large Cancer Hubs in London and Milan.

The SARS-CoV-2 (COVID-19) pandemic is having a large effect on the management of cancer patients. This study reports on the approach and outcomes of cancer patients receiving radical surgery with curative intent between March and September 2020 (in comparison to 2019) in the European Institute of Oncology, IRCCS (IEO) in Milan and the South East London Cancer Alliance (SELCA). Both institutions implemented a COVID-19 minimal pathway where patients were required to self-isolate prior to admission and were swabbed for COVID-19 within 72 h of surgery.

Is there a role for physical activity interventions in the treatment pathway of bladder cancer? A scoping review of the literature.

Introduction: Physical activity (PA) interventions have been introduced in patients with cancer as they may contribute to better treatment outcomes and quality of life (QoL). However, little is known about the impact of PA on patients with bladder cancer (BC). This scoping review aimed to explore efficacy and feasibility of existing PA interventions in the BC care pathway.

F.L. de Castelnau's collection of fishes from the Cape of Good Hope described by Pieter Bleeker.

The Dutch ichthyologist Pieter Bleeker described 34 species, including a new genus and five new species from a collection of fishes sent to him from the Cape of Good Hope by the French explorer, naturalist and diplomat, F.L. de Castelnau in 1858.

A new species of Nemipterus (Pisces: Nemipteridae) from the Western Indian Ocean.

A new species of threadfin bream, Nemipterus elaine, from the Western Indian Ocean is described. The new species is known so far only from off the coast of southern Mozambique, and appears most closely related morphologically and genetically to N. randalli Russell, 1986, but differs in having shorter pectoral and pelvic fins, and the upper caudal lobe produced to form a short, bright yellow filament (a long red trailing filament present in N.

Systemic pro-inflammatory response identifies patients with cancer with adverse outcomes from SARS-CoV-2 infection: the OnCovid Inflammatory Score.

Background: Patients with cancer are particularly susceptible to SARS-CoV-2 infection. The systemic inflammatory response is a pathogenic mechanism shared by cancer progression and COVID-19. We investigated systemic inflammation as a driver of severity and mortality from COVID-19, evaluating the prognostic role of commonly used inflammatory indices in SARS-CoV-2-infected patients with cancer accrued to the OnCovid study.
