The outcome components were also examined in relationship to their associations with various factors.

Methods: An anonymous self-administered questionnaire survey was conducted for 83 facilitators.

Lorazepam as a Cause of Drug-Induced Liver Injury.

Lorazepam is a benzodiazepine derivative that is globally used for the therapy of anxiety and insomnia. A 51-year-old Japanese man with yellowish discoloration of the eyes and skin and pruritus was admitted due to liver dysfunction. He had taken lorazepam approximately 5 months prior to this admission.

A wild Indo-Pacific bottlenose dolphin adopts a socially and genetically distant neonate.

Alloparental behaviour and adoption have been reported in many mammals and birds. Such behaviours are energetically costly, and their causes and functions remain unclear. We observed the adoption behaviour of a wild Indo-Pacific bottlenose dolphin (Tursiops aduncus) near Mikura Island, Japan.

Findings of the Work Improvement on Board (WIB) programme by the Fishery Agency in Japan.

Background: Concerns are growing about the safety and health of seamen exposed to high risks while working on vessels. Their accident rate in 2013 was 9.9 per 1000 workers, 5 times higher than that in industry.

Utility of action checklists as a consensus building tool.

The present study's objective was to determine the mechanisms for enhancing the utility of action checklists applied in participatory approach programs for workplace improvements, to identify the benefits of building consensus and to compare their applicability in Asian countries to find the most appropriate configuration for action checklists. Data were collected from eight trainees and 43 trainers with experience in Participatory Action-Oriented Training. Statistical analysis was performed in SPSS using the package PASW, version 19.

Practical ways to facilitate ergonomics improvements in occupational health practice.

Objective: Recent advances in participatory programs for improving workplace conditions are discussed to examine practical ways to facilitate ergonomics improvements.

Background: Participatory training programs are gaining importance, particularly in promoting occupational health and safety in small-scale workplaces. These programs have led to many improvements that can reduce work-related risks in varied situations.

Prevalence of self-reported finger deformations and occupational risk factors among professional cooks: a cross-sectional study.

Background: Previous studies have pointed out that the school lunch workers in Japan are suffering from work-related disorders including finger deformations. The purpose of this study was to investigate the prevalence of self-reported finger deformations and the association with job-related risk factors.

Methods: A cross-sectional questionnaire study of 5,719 subjects (response rate: 81%, 982 men and 4,737 women) was undertaken during September 2003 to February 2004.

Considerations of circadian impact for defining 'shift work' in cancer studies: IARC Working Group Report.

Based on the idea that electric light at night might account for a portion of the high and rising risk of breast cancer worldwide, it was predicted long ago that women working a non-day shift would be at higher risk compared with day-working women. This hypothesis has been extended more recently to prostate cancer. On the basis of limited human evidence and sufficient evidence in experimental animals, in 2007 the International Agency for Research on Cancer (IARC) classified 'shift work that involves circadian disruption' as a probable human carcinogen, group 2A.

Fine-scale analysis of synchronous breathing in wild Indo-Pacific bottlenose dolphins (Tursiops aduncus).

We quantitatively analysed synchronous breathing for dyads in Indo-Pacific bottlenose dolphins at Mikura Island, Tokyo, Japan. For most cases, we observed dyads swimming in the same direction (97%), in close proximity (i.e.

Participatory intervention for workplace improvements on mental health and job performance among blue-collar workers: a cluster randomized controlled trial.

Objective: To explore the effect of participatory intervention for workplace improvement on mental health and job performance.

Methods: Eleven assembly lines were randomly allocated to six intervention and five control lines (47 and 50 workers, respectively). The primary outcome was defined as the improvement in the following measures during the intervention period: General Health Questionnaire and WHO Health and Work Performance Questionnaire.

Participatory support to farmers in improving safety and health at work: building WIND farmer volunteer networks in Viet Nam.

The government of Viet Nam places a high priority on upgrading the quality of farmers' lives. Providing adequate occupational safety and health (OSH) protection for all farmers is an important challenge. The Ministry of Labour, Invalids and Social Affairs (MOLISA) of Viet Nam trained WIND (Work Improvement in Neighbourhood Development) farmer volunteers.

Action-oriented use of ergonomic checkpoints for healthy work design in different settings.

Recent experiences in the action-oriented use of ergonomic checkpoints in different work settings are reviewed. The purpose is to know what features are useful for healthy work design adjusted to each local situation. Based on the review results, common features of ergonomic checkpoints used in participatory training programs for improving workplace conditions in small enterprises, construction sites, home work and agriculture in industrially developing countries in Asia are discussed.

Facilitating participatory steps for planning and implementing low-cost improvements in small workplaces.

In this paper, practical means of facilitating participatory steps taken in workplace improvement programs in small workplaces were reviewed. The reviewed programs included those organized by partners of our Asian inter-country network for small enterprises, construction sites, home workplaces and agricultural farms. Trainers who commonly acted as facilitators were found to play multiple roles in helping managers, workers and farmers take initiative and achieve immediate improvements.

[Development of a mental health action checklist for improving workplace environment as means of job stress prevention].

An action checklist for improving the workplace environment by means of enhancing mental health of workers (Mental Health Action Check List: MHACL) was developed. The use of the checklist for primary prevention was examined. MHACL was developed through three steps: (1) Review of related references and collection of improvement examples for designing a draft MHACL; (2) pilot application of the draft at industrial workplaces and trials at workshops of occupational health staff; and (3) proposing a new MHACL for general use in industry.

Effect of 2-(6-cyano-1-hexyn-1-yl)adenosine on ocular blood flow in rabbits.

Previously, we reported that a relatively selective adenosine A(2A) receptor agonist 2-(6-cyano-1-hexyn-1-yl)adenosine (2-CN-Ado) elicited ocular hypotension in rabbits (Journal of Pharmacological Sciences 2005;97:501-509). In the present study, we investigated the effect of 2-CN-Ado on ocular blood flow in rabbit eyes. An intravitreal injection of 2-CN-Ado increased ocular blood flow, measured by a non-contact laser flowmeter.
