Maternal Haemoglobin and Haematocrit During Pregnancy and Stillbirth Risk: A Prospective, Population‐Based Birth Cohort Study

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Maternal anaemia is a public health issue globally, associated with adverse maternal and neonatal outcomes. However, less is known about the effects of high haemoglobin (Hb) and haematocrit (Hct) on the risk of stillbirth. Objectives We assessed the dose–response effects of dynamic changes in maternal Hb and Hct across all ...

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Impact of heat exposure during immobilization‐induced de‐training and re‐training on aerobic capacity and haemoglobin mass

Experimental Physiology, EarlyView.
Abstract The aim of this work was to assess the effect of heat exposure on cardiorespiratory and haematological responses during de‐training and re‐training. Nineteen men (33.8 ± 2.7 years; 182 ± 5.7 cm, 84.4 ± 9.3 kg) completed 4 weeks of pre‐training followed by heat exposure (HEAT; n = 9) or control (CON; n = 10).

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Acute and Chronic Altitude-Induced Cognitive Dysfunction in Children and Adolescents [PDF]

, 2015
OBJECTIVE: To assess whether exposure to high altitude induces cognitive dysfunction in young healthy European children and adolescents during acute, short-term exposure to an altitude of 3450 m and in an age-matched European population permanently ...

High altitude adaptation, common high-altitude disorders and the effects of high altitude on mental health A narrative review

Sports Psychiatry
: Introduction: The human brain is a highly oxygen-dependent organ. Low environmental oxygen availability (e.g., hypobaric hypoxia at altitude) is a major challenge to the brain and numerous endogenous cellular and systemic hypoxia responses therefore ...

Influence of facial cooling on carotid body tonic activity and sensitivity

Experimental Physiology, EarlyView.
Abstract Facial cooling can increase ventilation and augment the hypoxic ventilatory response. Whole body cooling increases both carotid body tonic activity and sensitivity; however, whether isolated facial cooling induces similar carotid body hyperexcitability was unknown.

THE IMPACT OF PENILE CANCER TREATMENT ON SEXUAL RELATIONSHIPS: A QUALITATIVE ENQUIRY [PDF]

, 2012
Background: Penile cancer is a rare but highly treatable condition. Current guidance recommends the use of a surgical procedure to excise the primary tumour (and a margin of normal penile tissue).

Myths and methodologies: Exposure and measurements under normobaric hypoxia

Experimental Physiology, EarlyView.
Abstract Usually, settings of normobaric hypoxia underestimate the environmental hypoxia they are supposed to reproduce. The likely steady state of water vapour pressure within the human airways keeps the partial pressure of inspired oxygen very close to the assumed value, but this does not apply to the calculation of environmental hypoxia or ...
