New Journal – ChemTexts : The Textbook Journal of Chemistry

Table of Contents  |  Vol 1 no 1  March 2015

This online journal publishes texts for academic education in chemistry and biochemistry, with the aim of imparting contemporary knowledge to students at an exceptionally high didactic level. Typical texts offer self-consistent treatment of a topic which could be part of a textbook. These are thoroughly illustrated and may also include such supplementary material as animated presentations or videos.

The range of topics spans traditional areas of chemistry, such as organic, inorganic, and physical chemistry, plus analytical chemistry, technical chemistry, environmental and green chemistry, food chemistry, theoretical and computational chemistry, biochemistry and chemical biology. It also includes material in the rapidly emerging areas of nanotechnology, energy and security.

The peer-reviewed texts mirror the current state of knowledge, offering genuine improvements over existing textbook material.

Risks to Health Care Workers from Nano-Enabled Medical Products

Journal of Occupational and Environmental Hygiene  Volume 12, Issue 6, 2015;  DOI: 10.1080/15459624.2015.1006641

Nanotechnology is rapidly expanding into the health care industry. However, occupational safety and health risks of nano-enabled medical products have not been thoroughly assessed. This manuscript highlights occupational risk mitigation practices for nano-enabled medical products throughout their life cycle for all major workplace settings including (1) medical research laboratories, (2) pharmaceutical manufacturing facilities, (3) clinical dispensing pharmacies, (4) health care delivery facilities, (5) home health care, (6) health care support, and (7) medical waste management. It further identifies critical research needs for ensuring worker protection in the health care industry.

Vaccines developed for H5N1, H7N9 avian influenza strains

(Kansas State University 22 May 2015) Researchers have developed vaccines for H5N1 and H7N9, two new strains of avian influenza that can be transmitted from poultry to humans. The strains have led to the culling of millions of commercial chickens and turkeys as well as the death of hundreds of people.

New study challenges claims on aldehyde content of third generation e-cigarettes

(Wiley 21 May 2015) In January 2015 a report published as a research letter to the New England Journal of Medicine found that a third generation e-cigarette — an e-cigarette with variable power settings — set to the maximum power and long puff duration generated levels of formaldehyde that, if inhaled in this way throughout the day, would several times exceed formaldehyde levels that smokers get from cigarettes. Media worldwide accordingly reported this new health hazard of e-cigarettes

Persistent psychosis after abuse of high dose of zolpidem

Addict Health. 2014 Summer-Autumn;6(3-4):159-62.

BACKGROUND: Zolpidem is a non-benzodiazepine medication which selectively affects GABA A receptors and treats insomnia. There are numerous reports of psychosis following the consumption of zolpidem all of which recovered after stopping the medication.

CASE REPORT: A 27 year old male law student, who was treated with 10 mg zolpidem due to insomnia, increased the dosage to 500 mg during 3 months. Not only was his insomnia remained untreated, but also he gradually became isolated, suspicious, and aggressive, and dropped out of university. He was then hospitalized in a psychiatric ward for 2 months, and was treated with antipsychotics and gradual discontinuation of zolpidem. With no improvement in psychosis and sleep improvement he was discharged. After two weeks he was hospitalized again and went under electroconvulsive therapy (ECT) and antipsychotic therapy, and was discharged with relative improvement. Now, after three years, he is diagnosed with schizophrenia and with modest improvements he is under care and treatment.

CONCLUSION: Zolpidem is a fairly useful medication for treating sleep problems, especially improving beginning of sleep. However, physicians ýand clinicians should consider the conditions, predispositions, and personal and family history of types of psychosis, alcohol and drug abuse in the comprehensive assessment and treatment plan for patients with insomnia.
