Increasing the provision of mental health care for vulnerable, disaster-affected people in Bangladesh

Abstract: Background: Bangladesh has the highest natural disaster mortality rate in the world, with over half a million people lost to disaster events since 1970. Most of these people have died during floods or cyclones, both of which are likely to become more frequent due to global climate change. To date, the government’s post-disaster response strategy has focused, increasingly effectively, on the physical needs of survivors, through the provision of shelter, food and medical care. However, the serious and widespread mental health consequences of natural disasters in Bangladesh have not yet received the attention that they deserve. This Debate article proposes a practical model that will facilitate the provision of comprehensive and effective post-disaster mental health services for vulnerable Bangladeshis on a sustainable basis. Discussion: A series of socially determined factors render the women and the poor of Bangladesh particularly vulnerable to dying in natural disasters; and, for those who survive, to suffering from some sort of disaster-related mental health illness. For women, this is largely due to the enforced gender separation, or purdah, that they endure; while for the poor, it is the fact that they are, by definition, only able to afford to live in the most climatically dangerous, and under-served parts of the country. Although the disasters themselves are brought by nature, therefore, social determinants increase the vulnerability of particular groups to mental illness as a result of them. While deeply entrenched, these determinants are at least partially amenable to change through policy and action. Summary: In response to the 2004 Indian Ocean tsunami, the World Health Organisation developed a framework for providing mental health and psychosocial support after major disasters, which, we argue, could be adapted to Bangladeshi post-cyclone and post-flood contexts. The framework is community-based, it includes both medical and non-clinical components, and it could be adapted so that women and the poor are actively sought out and provided for. After training, these services could be run by Bangladesh’s pre-existing 50,000-strong Cyclone Preparedness Programme workforce, alongside the country’s extensive network of community-based health workers.

Anti-emetic drugs in oncology: pharmacology and individualization by pharmacogenetics.

Abstract: Objective Nausea and vomiting are the most distressful side effects of cytotoxic drugs in cancer patients. Antiemetics are commonly used to reduce these side effects. However, the current antiemetic efficacy is about 70–80% in patients treated with highly-emetogenic cytotoxic drugs. One of the potential factors explaining this suboptimal response is variability in genes encoding enzymes and proteins which play a role in metabolism, transport and receptors related to antiemetic drugs. Aim of this review was to describe the pharmacology and pharmacogenetic concepts of of antiemetics in oncology. Method Pharmacogenetic and pharmacology studies of antiemetics in oncology published between January 1997 and February 2010 were searched in PubMed. Furthermore, related textbooks were also used for exploring the pharmacology of antiemetic drugs. The antiemetic drugs which were searched were the 5-hydroxytryptamine 3 receptor antagonists (5-HT3RAs), dopamine antagonists, corticosteroids, benzodiazepines, cannabinoids, antihistamines and neurokinin-1 antagonists. Result The 5-HT3RAs are widely used in highly emetogenic chemotherapy in combination with dexamethasone and a neurokinin-1 antagonist, especially in acute phase. However, the dopamine antagonists and benzodiazepines were found more appropriate for use in breakthrough and anticipatory symptoms or in preventing the delayed phase of chemotherapy induced nausea and vomiting. The use of cannabinoids and antihistamines need further investigation. Only six articles on pharmacogenetics of the 5-HT3RAs in highly emetogenic chemotherapy are published. Specifically, these studies investigated the association of the efficacy of 5-HT3RAs and variants in the multi drug resistance 1 (MDR1) gene, 5-HT3A,B and C receptor genes and CYP2D6 gene. The pharmacogenetic studies of the other antiemetics were not found in this review. Conclusion It is concluded that pharmacogenetic studies with antiemetics are sparse. It is too early to implement results of pharmacogenetic association studies of antiemetic drugs in clinical practice: confirmation of early findings is required.

Influence of the mycorrhizal fungus, Glomus coronatum, and soil phosphorus on infection and disease caused by binucleate Rhizoctonia and Rhizoctonia solani on mung bean (Vigna radiata)

Abstract: Root-infecting fungal pathogens and also parasites, which do not cause major disease symptoms cause problems of contamination in pot cultures of arbuscular mycorrhizal (AM) fungi We investigated the effect of the AM fungus, Glomus coronatum Giovannetti on disease caused by binucleate Rhizoctonia sp (BNR) and R solani in mung bean in the absence (P0) and presence (P1) of added soil phosphorus (P) When G coronatum and BNR or R solani were inoculated at the same time, G coronatum improved the growth of the plants and reduced colonization of roots by BNR, but not by R solani R solani reduced the growth of non-mycorrhizal mung bean in P0 soil 6 weeks after inoculation, whereas BNR had no effect on growth G coronatum reduced the severity of disease caused by BNR or R solani on mung bean in both soil P treatments When G coronatum was established in the roots 3 weeks before BNR or R solani was added to the potting mix, there was no significant effect of BNR or R solani on growth of mung bean Prior colonization by G coronatum slightly reduced indices of disease caused by BNR or R solani In both experiments, addition of P stimulated plant growth and reduced the colonization of roots by BNR, but had little effect on disease severity We conclude that the reduction of the effect of BNR or R solani on mung bean could not be explained by improved P nutrition, but could be attributed to the presence of G coronatum within and among the roots

Climate change and the regulation of wood formation in trees by temperature

Abstract: A better understanding of the influence of environmental conditions on wood formation should help to improve the radial growth of trees and to prepare for climate change. The cambial activity of trees is associated with seasonal cycles of activity and dormancy in temperate zones. The timing of cambial reactivation in early spring and dormancy in autumn plays an important role in determination of the cambial growth and the environmental adaptivity of temperate trees. This review focuses on the temperature regulation of the timing of cambial reactivation and xylem differentiation and highlights recent advances of bud growth in relation to cambial activity of temperate trees. In addition, we discuss relationships between the timing of cambial reactivation, start of xylem differentiation and changes in levels of storage materials to identify the source of the energy required for cell division and differentiation. We also present a summary of current understanding of the effects of rapid increases and decreases in temperature on cambial activity, by localized heating and cooling, respectively. Increases in temperature from late winter to early spring influence the physiological processes that are involved in the initiation of cambial reactivation and xylem differentiation both in localized heated stems and under natural conditions. Localized cooling has a direct effect on cell expansion, the thickening of walls of differentiating tracheids, and the rate of division of cambial cells. A rapid decrease in temperature of the stem might be the critical factor in the control of latewood formation and the cessation of cambial activity. Therefore, temperature is the main driver of cambial activity in temperate trees and trees are able to feel changes in temperature through the stem. The climate change might affect wood formation in trees.
