The objective of this study was to examine the relation between acne and cigarette smoking in a case-control study. METHODS A questionnaire on smoking habits was offered to 350 patients with acne vulgaris and 350 patients suffering from skin diseases other than acne, aged 15-40 years, a...

An identity-based (ID-based) universal designated verifier signature (ID-UDVS) scheme allows a signature holder to designate a specific verifier of the signature by using a simplified public identity such as e-mail address. In the paper, we present an efficient identity-based universal designated multi-verifiers signature (ID-UDMVS) scheme by extending a single verifier to a set of multi-verifi...

Data from a National Cancer Institute-designated comprehensive cancer center taking part in the ONS Foundation-supported Breast Cancer Care Quality Measures Set pilot study revealed a lack of interventions recommended for patient-reported symptoms of fatigue. A team was formed to address the issue using the steps of the evidence-based practice process and to implement practice changes. This art...

OBJECTIVE To determine the physical and chemical stability of cefazolin sodium reconstituted with sterile water for injection and stored in polypropylene syringes or diluted with either 5% dextrose in water (D5W) or 0....

BACKGROUND The Word Health Organization's Framework Convention on Tobacco Control calls on parties to implement evidenced-based tobacco control policies, which includes Article 8 (protect the public from exposure to tobacco smoke), and Article 13 (tobacco advertising, promotion and sponsorship (TAPS)). In 2015, Uganda passed the Tobacco Control Act 2015 which includes a comprehensive ban on smo...

Identity based cryptosystem simplifies the key management and revocation problem. Here we propose an Identity Based Strong Designated Verifier Signature (IBSDVS) scheme using bilinear pairings. The Designated Verifier Signature scheme described in [10] is identity based but it suffers from the deligatability as pointed out in [4]. We analyse the security of the scheme and show that the problem ...

BACKGROUND Currently, there is little understanding of the relationship between the strength of workplace smoking policies and the likelihood and duration, not just the likelihood, of exposure to secondhand smoke at work. METHODS This study assessed self-reported exposure to secondhand smoke at work in hours per week among a cross-sectional sample of 3650 Massachusetts adults who were employe...

Smoking is the most significant modifiable risk factor for bladder cancer, yet this is not well known outside of the medical community. Previous studies have found 3658% of urology patients can identify smoking as a risk factor for bladder cancer. We studied knowledge of cancer risk factors among members of the general public.215 participants over 18 years of age were recruited from the waiting...

BACKGROUND Smoking is a major risk factor for cot death. Many infants smoke passively as a result of parental smoking. This paper reports on infants exposed to a smoking environment and how they accumulate metabolites of cigarette smoke, such as cotinine, which may be physiologically harmful. AIM To assess cotinine levels in infants of smoking parents. METHOD Cotinine excretion in urine was...

Anecdotal evidence implies that students use library spaces for spiritual practices at many colleges and universities. Using focus groups, the authors investigated students' prayer behaviors on four regional campuses of a large research university, asking questions about frequency prayer, campus areas used devotions, ideal space. Students all religious or observances. However, they indicated ro...
