Depressive disorders are common. As compared to the general population, healthcare personnel are hypothesized to have an above than average risk to develop this condition. The aim of this study is to assess the prevalence of this condition and its contributing factors amongst primary healthcare personnel.
Methods: A cross-sectional study was conducted by universally sampling 179 primary healthcare personnel at nine primary healthcare centers across Kuala Lumpur and Selangor in May 2015. Depressive symptoms were screened using self-administered Patient Health Questionnaire-9 (PHQ-9) questionnaire. Socio-demographic and work profile data were also assessed.
Results: 92.7% of the 179 personnel agreed to participate. Near half of the respondents were staff nurses (49%), followed by doctors (22%), assistant medical officers (10%), attendants (10%) and the remaining were pharmacists, dieticians, and laboratory technicians (9%). Depression was found to be present in 38% of the participants with one-third found to have moderate to severe depression. Bivariate analysis show that males (p=0.043), assistant medical officers (p=0.048), and working more than 10 hours per day (p=0.019) are significant risk factors. Further analysis by logistic regression shows that working more than 10 hours per day increases the odds of depression by 3.1 (OR 3.1, 95% CI 1.1-8.7, p=0.03).
Conclusions: A high prevalence of depression was found within the healthcare personnel population at the primary healthcare centres studied. Being a male, employed as an assistant medical officer, and, prolonged hours at the workplace is a significant risk factor for depression.
Complete chloroplast genomes of 17 samples from six species of Colocasia (Araceae) were sequenced, assembled, and aligned together with two previously reported complete genome sequences from taro (Colocasia esculenta). Analysis provides a well-supported phylogenetic tree for taro and closely-related wild Colocasia species in Southeast Asia. Two chloroplast lineages (CI and CII) form a well-defined haplotype group and are found in cultivated taros known as var. esculenta (dasheen, CI), var. antiquorum (eddoe, CII), and in a widespread, commensal wild form known as var. aquatilis (CI). A third lineage (CIII) is also found in wild taros known as var. aquatilis and in the wild species C. lihengiae, C. formosana, and C. spongifolia. We suggest three different scenarios to explain the grouping of CIII wild taros (C. esculenta) with other wild Colocasia species. Chloroplast lineages CI and CIII in C. esculenta and an unknown parent species may be involved in an as yet undated history of hybridization, chloroplast capture, and range extension. Substantial taxonomic revision may be needed for C. esculenta after further studies of morphological and genetic diversity within the crop, in wild populations, and in closely related wild species. The results also point to the Bengal delta as a region of key interest for future research on the origins of tropical wetland taros.
