Predictors of attrition in a smoking cessation trial conducted in the lung cancer screening setting.

Significance: Although it is a requirement that tobacco treatment is offered to cigarette smokers undergoing low-dose computed tomographic lung cancer screening (LCS), not all smokers engage in treatment. To understand the barriers to tobacco treatment in this setting, we evaluated predictors of attrition in a smoking cessation trial among individuals undergoing LCS.

Methods: Prior to LCS, 926 participants, 50-80 years old, completed the baseline (T0) phone assessment, including demographic, clinical, tobacco, and psychological characteristics.

Clinical features and outcomes of nonconvulsive status epilepticus in a developing country: A 5-year retrospective study.

Background: This study aimed to determine the frequency of electrographically confirmed nonconvulsive status epilepticus (NCSE) in a cohort suspected with this condition and to determine the demographic/clinical profile, treatment, and outcomes of these patients in the context of a developing country, the Philippines.

Methods: We conducted a retrospective study among patients with suspected with NCSE admitted in the Philippine General Hospital from 2014 to 2019. Using the Salzberg 2013 criteria to diagnose NCSE, three electroencephalographers independently reviewed the electroencephalogram (EEG) tracings of suspected patients and were blinded from the clinical information.

Lung Cancer Screening in the Community Setting.

Background: Lung cancer has high incidence and high mortality burden, particularly because it is typically diagnosed in later stages. The National Lung Screening Trial demonstrated a lung cancer-specific mortality benefit in high-risk current and former smokers with yearly low-dose chest computed tomography (CT). Lung cancer screening is thus recommended, but it is unclear whether the results of the National Lung Screening Trial can be replicated in community settings.

Prospective CT screening for lung cancer in a high-risk population: HIV-positive smokers.

Background: Epidemiological evidence suggests that HIV-infected individuals are at increased risk of lung cancer, but no data exist because large computed tomography (CT) screening trials routinely exclude HIV-infected participants.

Methods: From 2006 to 2013, we conducted the world's first lung cancer screening trial of 224 HIV-infected current/former smokers to assess the CT detection rates of lung cancer. We also used 130 HIV-infected patients with known lung cancer to determine radiographic markers of lung cancer risk using multivariate analysis.

Annotation and structural elucidation of bovine milk oligosaccharides and determination of novel fucosylated structures.

Bovine milk oligosaccharides (BMOs) are recognized by the dairy and food industries, as well as by infant formula manufacturers, as novel, high-potential bioactive food ingredients. Recent studies revealed that bovine milk contains complex oligosaccharides structurally related to those previously thought to be present in only human milk. These BMOs are microbiotic modulators involved in important biological activities, including preventing pathogen binding to the intestinal epithelium and serving as nutrients for a selected class of beneficial bacteria.
