Risk reduction: perioperative smoking intervention

Smoking is a well-known risk factor for perioperative complications. Smokers experience an increased incidence of respiratory complications during anaesthesia and an increased risk of postoperative cardiopulmonary complications, infections and impaired wound healing. Smokers have a greater risk of postoperative intensive care admission. Even passive smoking is associated with increased risk at ope

Long-term recurrence and death rates after acute pancreatitis

The aim of this study was to compare long-term recurrence and death rates after a first episode of acute pancreatitis in patients with and without gallstones. Additionally, it was of interest to find out if there were factors predictive of readmission or death.

Effects of Intravenous Fluid Restriction on Postoperative Complications: Comparison of Two Perioperative Fluid Regimens: A Randomized Assessor-Blinded Multicenter Trial

Objective: To investigate the effect of a restricted intravenous fluid regimen versus a standard regimen on complications after colorectal resection.Summary Background Data: Current fluid administration in major surgery causes a weight increase of 3–6 kg. Complications after colorectal surgery are reported in up to 68% of patients. Associations between postoperative weight gain and poor survival a

Alcohol abuse and postoperative morbidity

Patients who drink too much have more complications after surgery. The aim of this thesis was to evaluate the evidence, possible mechanisms, and prevention of the increased postoperative morbidity in alcohol abusers, defined by a consumption of at least five drinks per day. The literature could be criticised for several methodological flaws. Nevertheless, the results are in agreement showing moder

Menstrual disturbances and fertility in chronic alcoholic women

Data on menstrual pattern, gynecological disorders and infertility were obtained from 51 chronic alcoholic women aged 20--42 years attending an outpatient clinic for alcoholics, using 51 randomly drawn age-matched healthy women as controls. A higher variability (P less than 0.05) in the duration of both menstrual cycle and menstrual flow was recorded in the chronic alcoholic women during active al

Treating trauma and substance use in adolescents

Up to 80% of adolescents have experienced trauma and one‐in‐seven suffer from post‐traumatic stress disorder (PTSD), a chronic, debilitating psychiatric disorder. For 50% of these adolescents, the course of their illness is further complicated by a co‐occurring substance use disorder, which often develops from repeated self‐medication of PTSD symptoms. Once established, both disorders serve to mai

Lens-Based Beamformer for Low-Complexity Millimeter-Wave Cellular Systems

Data rate requirements for cellular communications are expected to increase 1000–fold by 2020, compared to 2010. This is mainly because of the rapid increase in the number of wireless devices and data hungry applications per–device. This creates a formidable bandwidth crisis. Milimeter–wave (mmWave) systems with massive multiple–input multiple–output (MIMO) operation are two complementary concepts

Genetic diversity and ecosystem functioning in the face of multiple stressors

Species diversity is important for a range of ecosystem processes and properties, including the resistance to single and multiple stressors. It has been suggested that genetic diversity may play a similar role, but empirical evidence is still relatively scarce. Here, we report the results of a microcosm experiment where four strains of the marine diatom Skeletonema marinoi were grown in monocultur
