CONTEXT There is limited information that accounts for comorbidity on the impact of role disability associated with a wide range of mental and physical disorders in population-based samples. OBJECTIVE To estimate the comparative effects of common mental and physical conditions on role disability in the general population using a novel method that accounts for comorbidity. DESIGN Direct inte...

The increased interest in pain management by physicians in general and anaesthetists in particular over the last two decades, along with advances in our knowledge of nociceptive mechanisms, has led to the introduction of acute pain services. Many are based primarily on patientcontrolled analgesia (PCA), which has been shown to provide superior analgesia than conventional intramuscular opioid an...

This longitudinal study examined whether employees can impact their own well-being by crafting their job demands and resources. Based on the job demands-resources model, we hypothesized that employee job crafting would have an impact on work engagement, job satisfaction, and burnout through changes in job demands and job resources. Data was collected in a chemical plant at three time points wit...

The study investigates the relationship between education level, workplace learning behaviors, psychological empowerment and burnout in a sample of 191 teachers. We hypothesized that education level will positively affect psychological state of increased empowerment and decreased burnout, and we purposed that these effects will be mediated by workplace learning behaviors. We used multiple regre...

OBJECTIVE To investigate the incidence of asthma symptoms in young amateur swimmers, and to describe the clinical treatment of the children with asthma in a private sports club in the city of São Paulo, Brazil. METHODS The study included 171 amateur swimmers, ranging from 6 to14 years of age. All of the participants or their legal guardians were asked to complete the International Study of As...

High-altitude (HA) natives have blunted ventilatory responses to hypoxia (HVR), but studies differ as to whether this blunting is lost when HA natives migrate to live at sea level (SL), possibly because HVR has been assessed with different durations of hypoxic exposure (acute vs. sustained). To investigate this, 50 HA natives (>3,500 m, for >20 yr) now resident at SL were compared with 50 SL na...

BACKGROUND To study the influence of morphine on chemical control of breathing relative to the analgesic properties of morphine, the authors quantified morphine-induced analgesia and respiratory depression in a single group of healthy volunteers. Both respiratory and pain measurements were performed over single 24-h time spans. METHODS Eight subjects (four men, four women) received a 90-s int...

Depression is common in thepostpartumperiod. It can be severe and may have serious consequences for the woman and her child. The term postnatal depression, however, is often applied indiscriminately to all occurrences of psychological distress after childbirth. It is important to identify and to treat postnatal depression—recently published National Institute for Health and Clinical Excellence ...

To determine the relationship between hyperventilation and recovery of blood pH during recovery from a heavy exercise, short-term intense exercise (STIE) tests were performed after human subjects ingested 0.3 g.kg(-1) body mass of either NaHCO3 (Alk) or CaCO3 (Pla). Ventilation (VE)-CO2 output (VCO2) slopes during recovery following STIE were significantly lower in Alk than in Pla, indicating t...
