Hazardous Metal Pollution in the Republic of Fiji and the Need to Elicit Human Exposure

The fact that hazardous metals do not bio-degrade or bio-deteriorate translates to long-lasting environmental effects. In the context of evidently rapid global industrialization, this ought to warrant serious caution, particularly in developing countries. In the Republic of Fiji, a developing country in the South Pacific, several different environmental studies over the past 20 years have shown levels of lead, copper, zinc and iron in sediments of the Suva Harbor to be 6.2, 3.9, 3.3 and 2.1 times more than the accepted background reference levels, respectively. High levels of mercury have also been reported in lagoon shellfish. These data inevitably warrant thorough assessment of the waste practices of industries located upstream from the estuaries, but in addition, an exposure and health impact assessment has never been conducted. Relevant government departments are duty-bound, at least to the general public that reside in and consume seafood from the vicinities of the Suva Harbor, to investigate possible human effects of the elevated hazardous metal concentrations found consistently in 20 years of surface sediment analysis. Furthermore, pollution of the intermediate food web with hazardous metals should be investigated, regardless of whether human effects are eventually confirmed present or not.

Learning gain of pharmacy students after introducing guided inquiry learning with computer simulation in a pharmacology class in Fiji / 보건의료교육평가

PURPOSE: Active learning methods such as problem-based learning have been widely adopted in health professions education, although guided inquiry learning has been used only in limited settings. The objective of this study was to determine students' learning gain when guided inquiry learning was combined with computer simulation in a basic pharmacology course. METHODS: The second-year pharmacy students from Fiji National University participated in the study. Following classroom lectures on pharmacokinetics and pharmacodynamics, the students used tutor-prepared practice problems in groups of 3-4 to explore their concepts with Cyber Patient and Virtual Organ Bath software. Pre- and posttest assessments were administered to determine the learning gain from the exercises based on Hake's criteria. RESULTS: Forty-two students participated in the study. The average normalized learning gain from the pharmacokinetics exercises was 0.68. Thirty-seven participants (88.1%) achieved a significant learning gain, while 5 (11.90%) did not. The average normalized learning gain from the pharmacodynamics exercises was 0.76. Forty-one participants (97.6%) achieved a significant learning gain, while one participant (2.4%) did not. CONCLUSION: These results demonstrated that use of guided inquiry learning with computer simulations could produce significant learning gains with improvement in students' understanding of basic pharmacology.

Strengthening the admissions process in health care professional education: focus on a premier Pacific Island medical college / 보건의료교육평가

Relying solely on measures of intellectual aptitude and academic performance in university admissions can be disadvantageous to underprivileged students. The Fiji School of Medicine primarily uses such measures to evaluate and select student applicants, and the introduction of supplementary assessments could provide better access for students from disadvantaged backgrounds. This study examined the need for supplementary assessments in the admission process, types of additional assessments needed, and stakeholders' views on a multi-entry multi-exit strategy currently in use at the Fiji School of Medicine. A survey of the key stakeholders was conducted in February and March 2012 using closed and open ended questionnaire. One hundred and twenty-two validated questionnaires were self-administered by key stakeholders from the College of Medicine, Nursing and Health Sciences (CMNHS) and Fiji Ministries of Education and Health, with a response rate of 61%. Returned questionnaires were analysed quantitatively and qualitatively. Sixty-five percent of respondents supported the introduction of supplementary assessments, 49% favoured admissions test, and 16% preferred assessing non-academic factors. Many respondents supported the School's multi-entry multi-exit strategy as a 'good policy' that provided 'flexibility' and opportunity for students, but should be better regulated. These findings demonstrate the need for supplementary assessments in the selection process and for continued support for the use of multi-entry multi-exit strategy at the school.

The prevalence of HIV infection in women attending antenatal clinics in Fiji

@#HIV (human immunodeficiency virus) is an increasing concern in the South Pacific. We estimate, based on reported figures, that the prevalence of HIV infection in women attending antenatal clinics in Fiji in 2003 was 0.04%. The number of children born to HIV-positive mothers is small, though perinatal transmission appears to be high. Fiji's preliminary strategies for prevention of perinatal transmission have been significant, but require ongoing support and implementation.

A seroepidemiological study of hepatitis B amongst Fiji health care workers.

Hepatitis B immunization for health care workers is common policy in many countries where they constitute a particular at risk group. A seroepidemiological study of hepatitis B virus (HBV) in Fiji health care workers was conducted to determine whether this occupational group (or subgroups thereof) were at higher risk of infection than the general Fiji population. The purpose of this study was to ascertain whether health staff should be immunized, or whether it would be more productive to focus resources on neonatal immunization. Blood samples were obtained from 2,639 health workers and the sera analysed by radio-immunoassay for hepatitis B surface antigen (HBsAg), and hepatitis B surface antibody (anti-HBs). Prevalence rates of HBV markers of infection were compared with those observed in the general population, from a previous population-based cluster sample survey. Approximately 70% of the health care staff participated in the study. Prevalence of total HBV markers was 24%. The rate of HBsAg was 5%. Sex and ethnic group specific prevalence rates varied. Male subjects, Fijians and "other" Pacific Islanders all experienced higher rates of infection. Rural/urban and age related trends were also observed. Rates of infection in health staff were lower than those reported in the general population. Previous studies have indicated that most of the transmission of hepatitis B in hyperemdemic Pacific populations occurs at birth or within the next few years. There was no consistent pattern of hepatitis B infection in different occupational groups of health care workers. Certain relatively socially homogeneous subgroups of health workers were analysed separately, and among these health workers there was evidence for increased risk of infection due to exposure to blood or used hypodermic syringes, but not due to patient contact. Until health staff assume a higher risk of infection than the general Fijian population, efforts directed at community-wide control of hepatitis B continue to be the most appropriate use of resources.

Finger clubbing in match factory workers in Fiji.

This communication reports of two cases of digital clubbing in a factory manufacturing matches in Vitilevu, Fiji Islands. Both these cases were occupationally exposed to chemicals used in the manufacture of matches. They had physical contact with these chemicals including rhodamine B dye. Subjects who worked in the same factory area, including one worker who had FEV1.0 and FVC values below the predicted normal, but who did not handle chemicals showed no evidence of finger clubbing.
