Relationship between smoking and pulmonary tuberculosis based on positive sputum smears.

Introduction: Smoking and tuberculosis are the two major, global health problems. Not only active smokers but also passive smokers are at risk of becoming infected with tuberculosis. Through many mechanisms, smoking decreases immunity and predisposes to numerous infections.

Evaluation of mechanisms involved in regulation of intrinsic excitability by extracellular calcium in CA1 pyramidal neurons of rat.

It is well recognized that changes in the extracellular concentration of calcium ions influence the excitability of neurons, yet what mechanism(s) mediate these effects is still a matter of debate. Using patch-clamp recordings from rat hippocampal CA1 pyramidal neurons, we examined the contribution of G-proteins and intracellular calcium-dependent signaling mechanisms to changes in intrinsic excitability evoked by altering the extracellular calcium concentration from physiological (1.2 mM) to a commonly used experimental (2 mM) level.

Long-term safety of brazikumab in the open-label period of a randomized phase 2a study of patients with Crohn's disease.

Background: Short-term efficacy and safety of brazikumab (MEDI2070), a human monoclonal antibody and anti-p19 subunit inhibitor of interleukin-23, was demonstrated in a phase 2a trial in patients with moderate-to-severe active Crohn's disease (CD). We report brazikumab long-term safety and tolerability from the open-label period of this phase 2a study.

Methods: Patients who completed the 12-week, double-blind induction period were eligible for inclusion in an open-label period where all patients received subcutaneous brazikumab (210 mg) every 4 weeks for 100 weeks.

Characteristics of Pacific Island People Admitted to a New Zealand Inpatient Forensic Service.

This study describes the characteristics of Pacific Island patients admitted to the Auckland Regional Forensic Psychiatry Service, at Mason Clinic, the largest of five forensic hospitals in New Zealand. Sixty-nine Pacific Island patients admitted over a 9-year period (2009--2017) are described in terms of their sociodemographic and clinical characteristics, access to community mental health care prior to arrest, and their legal history. The majority were men, born in New Zealand, who were single, with poor educational achievement, unemployed, with minimal religious and cultural affiliations, and still living with family prior to the index offense.

Ion concentrations in cerebrospinal fluid in wakefulness, sleep and sleep deprivation in healthy humans.

Sleep is controlled by a circadian rhythmicity, via a reduction of arousal-promoting neuromodulatory activity, and by accumulation of somnogenic factors in the interstitial fluid of the brain. Recent experiments in mice suggest that a reduced neuronal excitability caused by a reduced concentration of potassium in the brain, concomitant with an increased concentration of calcium and magnesium, constitutes an important mediator of sleep. In the present study, we examined whether such changes in ion concentrations could be detected in the cerebrospinal fluid of healthy humans.
