Surviving a suicide attempt

Suicide is a global phenomenon in all regions of the world affecting people of all age groups. It has detrimental consequences on patients, their families, and the community as a whole. There have been numerous risk factors described for suicide including mental illness, stressful life situations, loss of social support, and general despair. The association of suicide with Islam has not been extensively studied. The common impression from clinical practice is that being a practicing Muslim reduces the risk of suicide. Another factor associated with suicide is starting a patient on antidepressants. However, this has been questioned recently. This report describes a middle-aged man with depression and multiple social stressors who survived a serious suicide attempt. The discussion will focus on the factors that lead him to want to end his life and the impact of the assumed protective factors such as religious belief and family support on this act of selfharm. Such patients can be on the edge when there is an imbalance between risk factors [such as depression, insomnia, and psychosocial stressors] and protective factors [like religious affiliation and family support]. All physicians are advised to assess the suicide risk thoroughly in patients with depression regardless of any presumed protective factor

Antimicrobial constituents from three endophytic fungi

OBJECTIVE@#To evaluate the antimicrobial potential of extracts of the endophytic fungi Plectophomella sp., Physalospora sp., and Crataegus monogyna (C. monogyna) and study the tentative identification of their active constituents.@*METHODS@#Crude extracts and isolated compounds were screened for antimicrobial activity using the agar well diffusion method. Four compounds were purified from three endophytic fungi using column chromatography and their structures have been assigned based on their (1)H and (13)C nuclear magnetic resonance spectra.@*RESULTS@#Plectophomella sp., Physalospora sp., and C. monogyna extracts showed promising antifungal, antibacterial and herbicidal properties. (-)-Mycorrhizin A was isolated from Plectophomella sp. while cytochalasins E and K were isolated from Physalospora sp. Similarly radicinin was purified from the endophytic fungus C. monogyna. The ethyl acetate extract of Plectophomella sp. showed significant antifungal activity towards Ustilago violacea (U. violacea) and Eurotium repens (E. repens) and significant antibacterial activity against Bacillus megaterium. Interestingly, the ethyl acetate extracts of Physalospora sp. and C. monogyna showed strong herbicidal and antifungal activities towards Chlorella fusca, U. violacea, E. repens, Mycotypha microspora (M. microspora), Fusarium oxysporum, Escherichia coli, and Bacillus megaterium. (-)-Mycorrhizin A showed significant antifungal activity towards U. violacea and E. repens. Cytochalasins E and K showed strong antifungal activity against E. repens and M. microspora especially towards fungal Mycotypha microspora. Similarly cytochalasins E and K showed good herbicidal activity towards Chlorella fusca. Radicinin showed strong antifungal activity against E. repens and M. microspora.@*CONCLUSIONS@#Antimicrobial activities demonstrated by the extracts of the endophytic fungi Plectophomella sp., Physalospora sp., and C. monogyna and four isolated compounds clearly demonstrate that these fungi extracts and active compounds present a great potential use in the food, cosmetic and pharmaceutical industries.

Analgesic effects of crude extracts and fractions of Omani frankincense obtained from traditional medicinal plant Boswellia sacra on animal models

Objective: To investigate the analgesic effect of Boswellia sacra (B. sacra), which could support the Omani traditional uses of frankincense for muscle, stomach, and arthritis pain. Methods: The crude extract, the essential oils and various sub-fractions of the crude methanol extract (each 300 mg/kg of the body weight of the animal) obtained from the resin of B. sacra were administered orally, and were evaluated for their analgesic activities by using two well known models of pain in mice, viz. acetic acid induced writhing test and formalin induced pain test in mice. Results: Of 13 samples, almost all of them were effective at an orally administered dose of 300 mg/kg of the body weight. The acetic acid induced writhes were inhibited in all the three phases with comparable values to the standard drug aspirin (300 mg/kg of body weight) with inhibition of 67.6% in phase I, 66.8% in phase II, and 37.9% in phase III. At the same time, all the tested samples were found effective in both the early and the late phases of formalin test. In formalin test, most of the tested samples showed more inhibitory effects as compared to the standard drug aspirin (300 mg/kg of body weight), which showed 36.2% and 29.6% inhibition in early and late phases respectively. Among the tested samples, the most significant inhibition was produced by Shabi frankincense oil (57.5% in early phase, and 55.6% in late phase). Interestingly, the extracts showed comparable percentage of inhibition to the oil and found in the following order: 60% chloroform. /n-hexane sub-fraction (55.3% in early phase, and 66.7% in late phase), and 70% chloroform. /n-hexane sub-fraction (59.6% in early phase, and 63.0% in late phase). Conclusions: The present study provided the scientific justification about the analgesic properties of the essential oils, extract, and various sub-fractions obtained from the resin of B. sacra, thus validating its use in traditional folk medicines and other products; and hence supporting the development in the analgesic properties of bioactive natural substances.

Emerging burden of frail young and elderly persons in Oman for whom the bell tolls?

Recent improvements in health and an increased standard of living in Oman have led to a reduction in environment-related and infectious diseases. Now the country is experiencing an epidemiological transition characterised by a baby boom, youth bulge and increasing longevity. Common wisdom would therefore suggest that Omanis will suffer less ill health. However, a survey of literature suggests that chronic non-communicable diseases are unexpectedly becoming common. This is possibly fuelled by some socio-cultural patterns specific to Oman, as well as the shortcomings of the 'miracle' of health and rapid modernisation. Unfortunately, such new diseases do not spare younger people; a proportion of them will need the type of care usually reserved for the elderly. In addition, due to their pervasive and refractory nature, these chronic non-communicable diseases seem impervious to the prevailing 'cure-oriented' health care system. This situation therefore calls for a paradigm shift: a health care system that goes beyond a traditional cure-orientation to provide care services for the chronically sick of all ages
