OBJECT Identifying risk factors for surgical morbidity and mortality might improve the safety and efficacy of neurosurgical intervention. Cigarette smoking is a relatively common practice and is associated with several adverse health outcomes. The authors examined the relationship between smoking and intraoperative blood loss, postoperative outcomes, and survival following craniotomy for tumor ...

BACKGROUND Smoking may hamper female fertility, probably modifying ovarian reserve. Antimüllerian hormone (AMH) is an accurate marker for ovarian reserve. AIM To look for an association between smoking status and plasma AMH concentration. PATIENTS AND METHODS A cohort of 141 infertile women in a university setting in Santiago, Chile was studied. Demographic and smoking data, including the n...

The increase in levels of blood nicotine that occurs from smoking a single cigarette, sometimes referred to as a “nicotine boost,” is an individualized measure of how much nicotine has been extracted from smoking a cigarette. This study investigated the demographic, smoking status, and psychological predictors of nicotine boost in a sample of 190 treatment-seeking smokers. Boost was assessed by...

BACKGROUND Cambodia has very high rates of tuberculosis and smoked tobacco use among adults. Efforts to control both tobacco use and tuberculosis in Cambodia need to be informed by nationally representative data. Our objective is to examine the relation between daily cigarette smoking and lifetime tuberculosis (TB) history in a national sample of adults in Cambodia. METHODS In 2011, a multi-s...

There is increasing concern over whether environmental exposures early in life may impact health in adulthood. Recent evidence suggests that prenatal or childhood exposure to cigarette smoke may result in poorer reproductive health later in life. Among 2,162 nonsmoking women recruited from three Boston, Massachusetts, clinics who underwent assisted reproductive treatments between 1994 and 2003,...

Background: Smoking is one of the major modifiable non-communicable disease risk factors. Our aim was to report the pattern of active and passive smoking using the data collected through a population base household survey in Kerman, Iran. Methods: Given a cluster random sampling design, we recruited 5900 adult populations (15-75 years old) into a survey. After consenting, every participant was ...

At the end of a multifactorial cardiovascular preventive trial serum thiocyanate was measured in random samples of 1035 cases and 1087 controls. A cut-off point 0.45 mg/dl (77.6/mumol/l) gave a sensitivity of 82.1% among the cigarette smokers in the control group and a specificity of 91.0% among the non-smokers. When the intervention and control groups are compared in terms of self-reported smo...

A microscopic study was made to determine the relationship between various lung parenchymal changes, smoking habits and age. The subjects were 1,824 men and women for whom a macroscopic study of pulmonary emphysema has previously been reported. Lung parenchymal changes included rupture of alveolar septa (emphysema), fibrasis, and thickening of small arteries and arterioles. The mean degree of e...

We analyzed data from a longitudinal cohort study of persons who inject drugs (PWID) in Tijuana, Mexico, to explore whether cigarette smoking increases the risk of interferon gamma release assay (IGRA) conversion. PWID were recruited using respondent driven sampling (RDS). QuantiFERON-TB Gold In-Tube (QFT) assay conversion was defined as interferon-gamma concentrations <0.35 IU/mL at baseline a...
