Childhood family stress and adult resilience in a sample of depressed patients.

BACKGROUND: The aim of this study is to explore the effect of childhood family stress on depression, personal, and social resilience in depressed patients. METHODS: We assessed childhood family stress (RFQ), depression (BSI, depression subscale), and resilience (RSA) in 152 depressed patients, 70 males, and 82 females. We calculated the 33rd and 66th percentiles of RFQ scores to divide the sample among Low, Medium, and High RFQ subgroups. A one-way ANOVA has been carried out to explore the differences between the variables in the subgroups. Finally, two regression analyses with depression, as the dependent variable, and resilience, divided for stress-sensitive and no stress-sensitive factors as independent variables, have been implemented. RESULTS: The one-way ANOVA showed that the Low subgroup had a positive profile, the Medium had an intermediate profile, while the High had a negative one for depression, personal (structured style and social competence), and interpersonal (social resources) resilience. The other factors (perception of self, planned future, and family cohesion) did not show differences in the subgroups, suggesting they are no stress sensitive. Regression analysis showed that no stress-sensitive factors have a constant and significant predictive value for depression in all subgroups; while, stress-sensitive ones showed a growing predictive value for depression from Low to Medium, but not in High, suggesting a ceiling effect. LIMITATIONS: The use of self-report measures, the cross-sectional nature of the study, and the lack of a non-clinical and/or outpatient samples. CONCLUSIONS: This study provides a contribution to the understanding of the effect of childhood family stress on adult resilience and depression.

Combined use of WEB2170 and HBO therapy can reduce ischemia and reperfusion injury to the skeletal muscle in a rabbit model.

Ischemia/reperfusion injury is regarded as the main cause of failure in revascularization of limbs and transfer of free flaps in the so called nonreflow phenomenon. This type of damage is caused by the production of free radicals, above all, of neutrophils that release great quantities of extracellular superoxide through the action of a membrane enzyme. In our study we used 40 white rabbits. Rabbit rectus femoris muscle is perfused by a single artery and vein and is therefore a valuable model for study of ischemia-induced reperfusion injury of skeletal muscle. The objective of this study was to individualize a valid method of protection for the muscle from damage by ischemia-induced reperfusion injury. We have tested the effectiveness of WEB2170, a PAF antagonist, of hyperbaric oxygen therapy one (HBO), and of combined employment of WEB2170 and HBO. The results show that both PAF and HBO play important protective roles against damage from ischemia/reperfusion injury, and that the combined employment of both therapies has a synergistic effect. We propose therefore a new therapeutic protocol for the prevention of damage resulting from ischemia/reperfusion injury with the simultaneous employment of this PAF and HBO.
