Oxygen control in cell culture - Your cells may not be experiencing what you think!

Oxygen (O)-controlled cell culture has been pivotal in studying mammalian mechanisms of O sensing, regulation, and utilization. We posit, however, that O-controlled cell culture is paradoxically not controlling O. There is overwhelming evidence that the pericellular O is lower than the surrounding gas phase due to cellular O consumption.

Patient and clinician perspectives of an eHealth intervention for supporting cancer treatment in the UK: mixed methods evaluation of the eRAPID randomised controlled trial.

Objectives: During 2015-2018, a randomised controlled trial (RCT) evaluated eRAPID, an eHealth intervention designed to capture patient-reported symptoms online during cancer treatment. eRAPID provides patients with advice on when to self-manage or seek medical support. Clinicians accessed symptom reports within electronic patient records.

Health Supervision for Children and Adolescents With Sickle Cell Disease: Clinical Report.

Sickle cell disease (SCD) is a group of complex genetic disorders of hemoglobin with multisystem manifestations. The scope of this clinical report is such that in-depth recommendations for management of all complications is not possible. Rather, the authors present an overview focused on the practical management of children and adolescents with SCD and the complications that are of particular relevance to pediatric primary care providers.

Controlling Pericellular Oxygen Tension in Cell Culture Reveals Distinct Breast Cancer Responses to Low Oxygen Tensions.

In oxygen (O)-controlled cell culture, an indispensable tool in biological research, it is presumed that the incubator setpoint equals the O tension experienced by cells (i.e., pericellular O).

Modified Delphi panel consensus recommendations for management of severe aplastic anemia.

Severe aplastic anemia (SAA) is a rare hematologic condition for which there is no clear management algorithm. A panel of 11 experts on adult and pediatric aplastic anemia was assembled and, using the RAND/University of California, Los Angeles modified Delphi panel method, evaluated >600 varying patient care scenarios to develop clinical recommendations for the initial and subsequent management of patients of all ages with SAA. Here, we present the panel's recommendations to rule out inherited bone marrow failure syndromes, on supportive care before and during first-line therapy, and on first-line (initial management) and second-line (subsequent management) therapy of acquired SAA, focusing on when transplant vs medical therapy is most appropriate.

Measuring Pericellular Oxygen Tension for In Vitro Cell Culture.

Cell culture, the process of growing cells in conditions that mimic those in the body, is a key technique in biomedical research. Oxygen is not controlled in conventional cell culture, although chambers that control oxygen in the surrounding gas phase are commercially available. In both cases, it is valuable to understand the pericellular oxygen tension (i.

HIV-associated gut microbial alterations are dependent on host and geographic context.

HIV-associated changes in intestinal microbiota are believed to be important drivers of disease progression. However, the majority of studies have focused on populations in high-income countries rather than in developing regions where HIV burden is greatest. To better understand the impact of HIV on fecal microbiota globally, we compare the fecal microbial community of individuals in the U.

Patients And Methods: A prospective UK study in patients with new bladder cancer diagnoses at 13 NHS Trusts. The HRQoL data were collected at 3, 6, 9 and 12 months.

Controlling pericellular oxygen tension in cell culture reveals distinct breast cancer responses to low oxygen tensions.

Oxygen (O) tension plays a key role in tissue function and pathophysiology. O-controlled cell culture, in which the O concentration in an incubator's gas phase is controlled, is an indispensable tool to study the role of O . For this technique, it is presumed that the incubator setpoint is equal to the O tension that cells experience (.

Hypoxia-inducing cryogels uncover key cancer-immune cell interactions in an oxygen-deficient tumor microenvironment.

Hypoxia is a major factor shaping the immune landscape, and several cancer models have been developed to emulate hypoxic tumors. However, to date, they still have several limitations, such as the lack of reproducibility, inadequate biophysical cues, limited immune cell infiltration, and poor oxygen (O) control, leading to non-pathophysiological tumor responses. Therefore, it is essential to develop better cancer models that mimic key features of the tumor extracellular matrix and recreate tumor-associated hypoxia while allowing cell infiltration and cancer-immune cell interactions.

Lifestyle Factors in Patients with Bladder Cancer: A Contemporary Picture of Tobacco Smoking, Electronic Cigarette Use, Body Mass Index, and Levels of Physical Activity.

Background: Little is known about contemporary lifestyle choices in patients with bladder cancer (BC). These choices include carcinogenic risk factors and could affect fitness to receive treatments.

Objective: To evaluate the contemporary lifestyle choices in BC patients.

Hypoxia-inducing cryogels uncover key cancer-immune cell interactions in an oxygen-deficient tumor microenvironment.

Hypoxia, an important feature of solid tumors, is a major factor shaping the immune landscape, and several cancer models have been developed to emulate hypoxic tumors. However, to date, they still have several limitations, such as the lack of reproducibility, inadequate biophysical cues, limited immune cell infiltration, and poor oxygen (O ) control, leading to non-pathophysiological tumor responses. As a result, it is essential to develop new and improved cancer models that mimic key features of the tumor extracellular matrix and recreate tumor-associated hypoxia while allowing cell infiltration and cancer-immune cell interactions.

Online Symptom Monitoring During Pelvic Radiation Therapy: Randomized Pilot Trial of the eRAPID Intervention.

Purpose: Radiation therapy (RT) and chemoRT for pelvic cancers increase survival but are associated with serious treatment-related symptoms. Electronic-patient self-Reporting of Adverse-events: Patient Information and aDvice (eRAPID) is a secure online system for patients to self-report symptoms, generating immediate advice for hospital contact or self-management. This pilot study aimed to establish feasibility and acceptability of the system.

Evaluation for Bleeding Disorders in Suspected Child Abuse.

Bruising or bleeding in a child can raise the concern for child abuse. Assessing whether the findings are the result of trauma and/or whether the child has a bleeding disorder is critical. Many bleeding disorders are rare, and not every child with bruising/bleeding that may raise a concern for abuse requires an evaluation for bleeding disorders.

Sexual Activity, Function and Dysfunction After a Diagnosis of Bladder Cancer.

Background: Sexual dysfunction is common in those affected by cancer and local and radical treatments for Bladder Cancer (BC) can affect sexual function directly.

Aim: To evaluate sexual function following a bladder cancer (BC) diagnosis.

Methods: Self-reported sexual function was collected 10 years after a diagnosis of BC as part of a cross-sectional patient reported outcome measure (PROM) survey exploring life after BC diagnosis and treatment.

REDCap mobile data collection: Using implementation science to explore the potential and pitfalls of a digital health tool in routine voluntary medical male circumcision outreach settings in Zimbabwe.

Background: Digital data collection tools improve data quality but are limited by connectivity. ZAZIC, a Zimbabwean consortium focused on scaling up male circumcision (MC) services, provides MC in outreach settings where both data quality and connectivity is poor. ZAZIC implemented REDCap Mobile app for data collection among roving ZAZIC MC nurses.

The Diagnosis and Management of Recurrent Ischemic Priapism, Priapism in Sickle Cell Patients, and Non-Ischemic Priapism: An AUA/SMSNA Guideline.

Purpose: Priapism is a persistent penile erection that continues hours beyond, or is unrelated to, sexual stimulation and results in a prolonged and uncontrolled erection. Given its time-dependent and progressive nature, priapism is a situation that both urologists and emergency medicine practitioners must be familiar with and comfortable managing.

Methodology: A comprehensive search of the literature on acute ischemic priapism and non-ischemic priapism (NIP) was performed by Emergency Care Research Institute for articles published between January 1, 1960 and May 1, 2020.

Benthic infaunal assemblages adjacent to an ocean outfall in Australian marine waters: Impact assessment and identification of indicator taxa.

An impact assessment of oceanic effluent releases from Belmont wastewater treatment works (WWTW) in Newcastle, Australia, was undertaken. Benthic infaunal assemblages in sandy sediments of ~25 m water depth were examined, at sites adjacent to the release point, and at increasing distances up to 2 km in both a NE and SW direction over five consecutive years (2016-2020). Localised impacts were evident for infaunal assemblages, with sites within 20 m of the outfall ("Impact" site types) exhibiting lower taxa richness and Shannon diversity, higher abundances of polychaetes and/or nematodes, higher polychaete ratios, and shifts in assemblage composition in comparison to sites at greater distances during some years.

Quality of life after VATS lung resection and SABR for early-stage non-small cell lung cancer: A longitudinal study.

Introduction: Video-assisted thoracoscopic (VATS) lung resection is the recommended curative treatment for early-stage non-small cell lung cancer (NSCLC). Patients considered at high surgical risk, are treated with stereotactic ablative body radiotherapy (SABR) as a lower morbidity alternative. This study aims to investigate the impact of SABR and VATS resection on patients' quality of life (QoL) over the first year after treatment.
