RESUMO

Self-harming behavior (SHB) represents an important public health issue and is one of the most critical predictors of completed death by suicide. The current study evaluated the incremental contribution of the Interpersonal Theory of Suicide constructs of thwarted belongingness and perceived burdensomeness for the prediction of SHB beyond that associated with having a psychiatric diagnosis. Community adults from two different countries included a Portuguese sample of 414 adults, aged between 18 and 65 years (M = 45.09, SD = 13.11), and predominantly female (79%), and an American sample of 290 adults (198 men, 91 women, 1 unreported) with a mean age of 37.76 years (SD = 10.84) ranging from 20 to 71, who participated online. Results demonstrated mediation effects for perceived burdensomeness in the association of thwarted belongingness with SHB, partial mediation in the Portuguese sample and full mediation in the American sample. Findings also indicated that the interaction between thwarted belongingness and perceived burdensomeness failed to make a statistically significant contribution to the prediction of SHB. The results are discussed within the Interpersonal Theory of Suicide and its relevance for clinical practice.

RESUMO

OBJECTIVES: The association between childhood trauma and suicidal ideation has been well documented in several populations, including individuals with a substance use disorder (SUD). However, a gap still exists in the literature regarding the mechanisms by which childhood trauma later impacts suicide risk. This cross-sectional study tested the effect of childhood trauma on suicidal ideation, as well as the mediating effect of tolerance for psychological pain (managing the pain and enduring the pain) in that relationship, controlling for the effect of depressive symptoms, in individuals with a SUD. METHODS: A sample of 102 adults with a SUD participated in the study. Path analysis by structural equation modelling tested a mediation model. RESULTS: Depressive symptoms and lower levels of managing the pain were found to fully mediate the association between childhood trauma and suicidal ideation. CONCLUSIONS: Our results suggest that depressive symptoms and a lack of ability to manage psychological pain contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions in individuals with SUDs. Moreover, they have relevant implications for prevention and clinical interventions regarding suicidal ideation in this population. PRACTITIONER POINTS: Childhood trauma relates to suicidal ideation in individuals with a substance use disorder. Depressive symptoms contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions. A lack of ability to manage psychological pain also contributes towards explaining this relationship. The obtained results have relevant implications for the prevention of and clinical intervention for suicidal ideation in SUD individuals.

RESUMO

PURPOSE: To study structural chorioretinal changes in tamoxifen-treated patients. METHODS: Cross-sectional case-control study comparing structural chorioretinal aspects in tamoxifen-treated patients and healthy controls. Enhanced depth spectral domain optic coherence tomography with choroidal binarization and optic coherence tomography angiography were performed. Individual retinal layer thickness and chorioretinal vascular components were compared. Subgroup analysis regarding history of chemotherapy was performed. RESULTS: Two hundred eyes of 100 TAM-treated patients (Group 1) and 80 eyes of 40 healthy controls (Group 2) were included. Of the 200 spectral domain optic coherence tomography scans from patients, 2 showed structural changes attributable to tamoxifen. Group 1 showed significantly lower values in choroidal parameters and in total retinal, ganglion cell layer, inner plexiform layer, outer nuclear layer, and retinal pigment epithelial thicknesses as well as an increased thickness in the outer plexiform layer. The subgroup not submitted to chemotherapy maintained significant reductions in total retinal thickness, ganglion cell layer, retinal pigment epithelium, outer nuclear layer, outer retinal layer, choroidal parameters, as well as an increased thickness in the outer plexiform layer, in comparison with Group 2. CONCLUSION: Subclinical structural retinal changes could indicate early retinal pigment epithelial and photoreceptor damage. The new finding of choroidal thinning could point toward another important pathophysiologic process in tamoxifen-induced toxicity.

RESUMO

Tumor heterogeneity and the poor outcome of breast cancer (BC) patients have led researchers to define new markers of this disease. In recent years, microRNA expression patterns have proven to be valuable disease indicators. The level of miR-203a, in particular, was shown to be altered in different types of cancer. The objective of the present study was to assess the relationship between miR-203a expression and clinicopathological features of BC in a Portuguese cohort. The expression levels of miR­203a were analyzed in 109 formalin­fixed paraffin-embedded paired normal and tumor tissue samples. Significant overexpression of miR­203a in the tumor tissues was found (1.7-fold higher) compared to the expression in the normal adjacent tissues (p=0.003). In addition, several clinicopathological characteristics presented an association with higher miR-203a expression levels. Tumors with diameter ≤18.5 mm (1.5-fold; p=0.019), tumors positive for estrogen receptor (fold-change, 1.71; p=0.042), progesterone receptor (fold-change, 1.50; p=0.046) and negative for HER2 (fold-change, 1.50; p=0.016) and high Ki-67 index (fold-change, 2.60; p=0.024) presented a significant difference in miR-203a expression compared with adjacent normal tissues. Tumors without invasion of lymph nodes also presented higher expression of miR-203a (fold-change, 2.40; p=0.004). With regard to histological classification, ductal carcinomas in situ (fold-change, 2.20; p=0.028) and invasive carcinoma NOS (fold-change, 1.71; p=0.009) displayed significantly higher expression of miR-203a. Moreover, we found a significant downregulation of miR-203a with increased stage in invasive lobular carcinomas, suggesting that miR-203a could represent a potential marker to discriminate stages in invasive lobular carcinomas.

RESUMO

BACKGROUND: Gallstone ileus accounts for 1% to 4% of cases of mechanical bowel obstruction, but may be responsible for up to 25% of cases in older age groups. In non-iatrogenic cases, gallstone migration occurs after formation of a biliary-enteric fistula. In fewer than 10% of patients with gallstone ileus, the impacted gallstones are located in the pylorus or duodenum, resulting in gastric outlet obstruction, known as Bouveret's syndrome. CASE PRESENTATION: We report an 86-year-old female who was admitted to hospital with a 10-day history of persistent vomiting and prostration. She was in hypovolemic shock at the time of arrival in the emergency department. Investigations revealed a gallstone in the duodenal bulb and a cholecystoduodenal fistula. She underwent surgical gastrolithotomy. Unfortunately, she died of aspiration pneumonia on the fourth postoperative day. CONCLUSION: This case shows the importance of considering Bouveret's syndrome in the differential diagnosis of gastric outlet obstruction, especially in the elderly, even in patients with no previous history of gallbladder disease.
