Role of stressful and traumatic life events in obsessive-compulsive disorder

Whilst genetic factors are thought to contribute to the development of obsessive-compulsive disorder (OCD), the role of environmental factors in OCD is only beginning to be understood. In this article, we review the influence of stress-related factors in OCD. Overall, studies indicate that: patients with OCD frequently report stressful and traumatic life events before illness onset, although these rates do not seem to be significantly different from those described in other disorders; the association between OCD and post-traumatic stress disorder (PTSD) might result from symptom overlap, although cases of patients developing OCD after PTSD and showing obsessive-compulsive symptoms that were unrelated to trauma have been described fairly consistently; it is unclear whether patients with OCD and a history of stress-related factors (including stressful life events, traumatic life events or comorbid PTSD) may respond better or worse to the available treatments; and comorbid PTSD may modify the clinical expression of OCD-although controlled studies comparing pre-versus post-traumatic OCD patients are still unavailable. In conclusion, there is a growing evidence to suggest a role for stress-related factors in OCD. Although the available literature does not confirm the existence of a post-traumatic subtype of OCD, it does call for further systematic research into this topic. © 2011 Future Medicine Ltd.

Living kidney donors - a prospective study of quality of life before and after kidney donation

Although the safety of living kidney donation has been well established, prospective studies examining the physical and psychosocial aspects of the donor's quality of life are still scarce. Thus, the purpose of this prospective work was to assess the quality of life of 50 consecutive donors before and after kidney transplantation. All donors were asked to respond to both a donor questionnaire and the short-form 36-item health survey (SF-36). Interviews were individually conducted before, three months after, and over one yr after transplantation. Donation was considered a positive experience by all patients and had no impact on any physical or psychosocial aspect of the donor's life. Improved self-esteem and better quality of life after donation were reported in 52% of the cases. All donors would donate again and encouraged donation. SF-36 data indicated improvement in post-donation mental and physical scores among living donors closely related to recipient. Overall, most donors had a positive experience, felt no changes in quality of life, experienced enhanced self-esteem, would donate again, and recommended donation. © 2012 John Wiley & Sons A/S.

Mangrove habitat partitioning by Ucides cordatus (Ucididae): Effects of the degree of tidal flooding and tree-species composition during its life cycle

Environmental factors strongly affect mangrove crabs, and some factors modulate population structure and habitat partitioning during the crabs' life cycle. However, the effect of these environmental factors on habitat selection by mangrove crabs is still unknown. We evaluated habitat selection by the mangrove crab Ucides cordatus in mangrove forests with different degrees of predominance of Rhizophora mangle, Laguncularia racemosa or Avicennia schaueriana, two tidal flooding levels (less- and more-flooded), and two biological periods (breeding and non-breeding seasons). Sampling was conducted in four mangrove forests with different influences of these biotic and abiotic parameters. We used the data for sex ratio to explain environmental partitioning by this species. Females predominated in R. mangle mangroves, independently of the biological period (breeding or non-breeding seasons), and males predominated only in the less-flooded L. racemosa mangroves. The flooding level affected the sex ratio of U. cordatus, with a predominance of males in less-flooded mangroves, independently of the biological period; and a gender balance in the more-flooded mangroves only during the breeding season. Outside the breeding season, the largest specimens were recorded in the R. mangle mangroves, but in the breeding season, the largest crabs were recorded in the L. racemosa mangroves with a higher level of flooding. These results suggest that tree-species composition and tidal flooding level can have a significant effect on the habitat partitioning of sexes and sizes of the mangrove crab U. cordatus both during and outside the breeding season. © 2012 Springer-Verlag and AWI.

Oral health associated with quality of life of people living with HIV/AIDS in Brazil

Background: The epidemic of HIV/AIDS enters into its fourth decade and is still considered an important public health problem in developed and developing countries. The purpose is verify the oral health and other factors that influence the quality of life of people living with HIV/AIDS attending a public service reference in Brazil.Methods: The participants answered the questionnaire on socio-demographic conditions, issues related to HIV and daily habits. The quality of life was analyzed by the HIV/AIDS Targeted Quality of Life (HAT-QoL) instrument with 42 items divided into nine domains: General Activity, Sexual Activity, Confidentiality concerns, Health Concerns, Financial Concern, HIV Awareness, Satisfaction with Life Issues related to medication and Trust in the physician. The oral health data were collected by means of the DMFT index, use and need of dentures and the Community Periodontal Index, according to the criteria proposed by the World Health Organization, by a calibrated researcher. Bivariate and multiple linear regressions were performed.Results: Of the participants, 53.1% were women and had a mean age of 42 years, 53.1% had eight years or less of schooling and 20.3% were not employed. In analyzing the quality of life domain of the HAT-QoL, with a lower average there was: Financial concern (39.4), followed by Confidentiality concern (43.2), Sexual activities (55.2) and Health concerns (62. 88). There was an association between the variables: do not have link to employment (p < 0.001), is brown or black (p = 0.045), alcohol consumption (p = 0.041), did not make use of antiretroviral therapy (p = 0.006), high levels of viral load (p = 0.035) and need for dentures (p = 0.025), with the worse quality of life scores.Conclusion: Socioeconomic and inadequate health conditions had a negative impact on the quality of life of people with HIV/AIDS.
