A Proposal on Neurological Dose–Response Relationship for Inclusion in ISO 5349-1 Documentation to be Used in Tropical Environment

The objective of this paper is to calculate the association between the eight-hour time weighted average vibration exposure, A(8) and years of vibration exposure in the tropical environment using the results of hand-arm vibration syndrome (HAVS) study conducted among a total of 173 male construction, forestry, and automobile manufacturing plant workers in Malaysia. We found that the relationship between A(8) and years of vibration exposure for neurological symptoms in tropical environment is similar to finger blanching as reported in the ISO 5349-1 document. The dose–response relationship of HAVS in a tropical environment is valid for finger tingling and numbness. Hence, we proposed to include the dose–response relationship information for neurological symptoms in the ISO 5349-1 document to facilitate its application in tropical environment

Mortality of elder financial and psychological abuse victims in rural Malaysia: a prospective cohort study

To determine the longitudinal impact of elder financial and psychological abuse on risk of death among older Malaysians. Design 7-year prospective cohort study. Baseline data were collected in late 2013 and respondents were followed up in June 2020. Setting Kuala Pilah, Negeri Sembilan, Malaysia. Participants 1927 community-dwelling older adults aged 60 or older randomly sampled from the national census. Individuals with severe cognitive impairment were excluded. Outcome measure Mortality data were provided by the Malaysian National Registration Department and linked to respondents’ national identification numbers. Kaplan-Meier curves and Cox regression were used to examine victims’ survival periods and the impact of abuse on risk of death. Results Overall, 450 respondents (23.4%) died after 7 years. Among financial and psychological abuse victims, death percentage was 25.8% compared with 23.3% among those who did not experience these types of abuse. Kaplan-Meier curves showed shorter survival among abuse victims, but Cox regression found no significant impact of financial and psychological abuse on mortality risk (HR 1.05, 95% CI 0.78 to 1.41). Among all the variables studied, only cognitive impairment led to higher mortality risk (HR 1.32, 95% CI 1.03 to 1.69). Conclusion Our findings contradict prior empirical studies that supported the link between elder abuse and neglect (EAN) and mortality, even though we focused on two abuse subtypes. Results in this study are more in line with the recently emerging evidence that showed no association between EAN and mortality
