Airway and systemic biomarkers of health effects after short-term exposure to indoor ultrafine particles from cooking and candles - A randomized controlled double-blind crossover study among mild asthmatic subjects.

Background: There is insufficient knowledge about the systemic health effects of exposure to fine (PM) and ultrafine particles emitted from typical indoor sources, including cooking and candlelight burning. We examined whether short-term exposure to emissions from cooking and burning candles cause inflammatory changes in young individuals with mild asthma. Thirty-six non-smoking asthmatics participated in a randomized controlled double-blind crossover study attending three exposure sessions (mean PM µg/m polycyclic aromatic hydrocarbons ng/m): (a) air mixed with emissions from cooking (96.

Acute health effects from exposure to indoor ultrafine particles-A randomized controlled crossover study among young mild asthmatics.

Particulate matter is linked to adverse health effects, however, little is known about health effects of particles emitted from typical indoor sources. We examined acute health effects of short-term exposure to emissions from cooking and candles among asthmatics. In a randomized controlled double-blinded crossover study, 36 young non-smoking asthmatics attended three exposure sessions lasting 5 h: (a) air mixed with emissions from cooking (fine particle mass concentration): (PM : 96.

Robot-assisted surgery in a broader healthcare perspective: a difference-in-difference-based cost analysis of a national prostatectomy cohort.

Objective: To estimate costs attributable to robot-assisted laparoscopic prostatectomy (RALP) as compared with open prostatectomy (OP) and laparoscopic prostatectomies (LP) in a National Health Service perspective.

Patients And Methods: Register-based cohort study of 4309 consecutive patients who underwent prostatectomy from 2006 to 2013 (2241 RALP, 1818 OP and 250 LP). Patients were followed from 12 months before to 12 months after prostatectomy with respect to service use in primary care (general practitioners, therapists, specialists etc) and hospitals (inpatient and outpatient activity related to prostatectomy and comorbidity).

Health care cost consequences of using robot technology for hysterectomy: a register-based study of consecutive patients during 2006-2013.

The objective of this study is to examine the costs attributable to robotic-assisted laparoscopic hysterectomy from a broad healthcare sector perspective in a register-based longitudinal study. The population in this study were 7670 consecutive women undergoing hysterectomy between January 2006 and August 2013 in public hospitals in Denmark. The interventions in the study were total and radical hysterectomy performed robotic-assisted laparoscopic hysterectomy (RALH), total laparoscopic hysterectomy (TLH), or open abdominal hysterectomy (OAH).

Social relations, depressive symptoms, and incident type 2 diabetes mellitus: The English Longitudinal Study of Ageing.

Aims: We examined whether social relations are associated with the risk of developing type 2 diabetes mellitus (T2DM) and furthermore, whether social relations modify the association between depressive symptoms and incident T2DM. We hypothesized that the risk of developing T2DM would be lower for individuals with stronger social relations compared to those with weaker social relations, and that the association between depressive symptoms and incident T2DM would be attenuated for those with stronger social relations.

Methods: Non-diabetic participants (n=7662) of the "English Longitudinal Study of Ageing" (3398 men) aged 50-91years were followed until 2012/2013, after baseline assessment of depressive symptoms, social support, relational strain, and network size.

Characterization of the enhancement effect of Na2CO3 on the sulfur capture capacity of limestones.

It has been known for a long time that certain additives (e.g., NaCl, CaCl2, Na2CO3, Fe2O3) can increase the sulfur dioxide capture-capacity of limestones.

Kinetic study of hydrated lime reaction with HCl.

Hydrochloride (HCl) is an acidic pollutant present in the flue gas of most municipal or hazardous waste incinerators. Hydrated lime (Ca(OH)2) is often used as a dry sorbent for injection in a spray reactor to remove HCI. However, due to the short residence time encountered, this control method has generally been found to have low conversion efficiencies which results in the high lime usage and generates large amount of fly ash as solid wastes.
