RESUMO

CRH neurons are found in the paraventricular nucleus(PVN) and central amygdala(CeA) nuclei. This study investigated the effects of sub-chronic CRH administration into the PVN and CeA nuclei on food intake biomarkers in rats divided into five groups: control, two shams, and two CRH-PVN and CRH-CeA groups(receiving CRH in nuclei for seven days). The CRH-PVN group had significantly higher cumulative food intake and food intake trends than the CRH-CeA group. The CRH-CeA and CRH-PVN groups exhibited significant increases in food intake during hours 1 and 2, respectively. Moreover, to be time-dependent, food intake is modulated by different brain nuclei. The CRH signaling pathway appeared to be activated later in the PVN than CeA. Both groups exhibited significantly higher leptin levels, the CRH-PVN group exhibited higher ghrelin levels and lower glucose levels. Repetitive administration of CRH into the PVN and CeA significantly reduced body weight differences. CRH administration into the PVN affected both leptin and ghrelin levels, but ghrelin had a greater impact on glucose variations and cumulative food intake than leptin. Finally, CRH administration into the PVN and CeA likely activated the HPA axis, and the CeA had a greater impact on the stress circuit than on food intake behavior.

RESUMO

We evaluated the feasibility, reliability, and validity of a Spanish-language self-administered geriatric assessment (GA) in older (age ≥ 65) Spanish-speaking women with breast cancer in the United States. Eligible participants (n = 181) were recruited and randomized. Feasibility was defined as the participant's unassisted GA completion rate, completion time, and perception on ease of completion. Reliability and validity were assessed using Spearman's correlation coefficients. Two-sided p < 0.05 was considered significant. Ninety-eight percent of participants (n = 177) completed the GA at least once. Median age was 70 years (range: 65-95) and 55% had ≤8th grade education. Forty-one percent (n = 73) were unable to complete the GA unassisted, median completion time was 28 min (range 8-90), and 77% (n = 136) rated the GA as "easy"/"very easy". Patients with ≤8th grade education took longer to complete the GA (30 vs. 25 min, p = 0.0036) and needed more assistance (59% vs. 19%, p < 0.001) than those with ≥9th grade education. Test-retest reliability was high (≥0.82) for all domains except social activity (0.73). Validity among similar scales was found. The self-administered GA is a feasible, reliable, and valid tool for Spanish-speaking older women with breast cancer. Tailoring GA tools to the patients' educational level is important when implementing tools in multicultural environments.

RESUMO

Women with triple negative breast cancer (TNBC) have a high prevalence of BRCA1 mutations, and current clinical guidelines recommend genetic testing for patients with TNBC aged ≤60 years. However, studies supporting this recommendation have included few older women with TNBC. METHODS: Genetic testing results from women aged >60 years with TNBC enrolled in the Clinical Cancer Genomics Community Research Network (CCGCRN) registry were included in this analysis. Prevalence of breast cancer-associated pathogenic variants (PVs) was compared across age groups. RESULTS: We identified 151 women with TNBC aged >60 years (median 65 years; SD 5.3). Of these, 130 (86%) underwent genetic testing, and a breast cancer-associated PV was identified in 16 (12.3%; 95% CI 7-19): BRCA1 (n = 6), BRCA2 (n = 5), PALB2 (n = 2), ATM (n = 1) and RAD51C (n = 2). We found no differences in the proportion of patients with close blood relatives with breast (≤50 years) or ovarian cancer (any age) between PV carriers (37.5%) and non-carriers (34.2%) (p = 0.79). Among PV's carriers, the proportion of older women with a BRCA1 PV was lower when compared to younger women (37.5% vs 77.2%; p < 0.01). CONCLUSION: Breast cancer-associated PVs were found in an important proportion of women aged >60 years with TNBC undergoing genetic testing, including greater representation of BRCA2. These results suggest that older women with TNBC should be offered genetic testing, and that their exclusion based on chronologic age alone may not be appropriate.

RESUMO

OBJECTIVE: To identify scale validation studies for life quality evaluation in patients with bladder cancer. METHODS: Bibliographic search was performed on MEDLINE® via ovid, EMBASE, CENTRAL and LILACS. Subsequently, each of the articles was evaluated, identifying eligibility criteria. This information was confirmed and verified by the researchers, and in cases of missing information, the authors were contacted to complete the data. Due to the nature of the study, no statistical analysis was performed. RESULTS: From 1760 articles found, only 5were included in the qualitative analysis. Five validated questionnaires for quality of life in patients with bladder cancer (BCI, EORTC QLQ-NMIBC24, FACT-VCI, BUSS, FACT-BL). The BCI; most frequently used instrument in bladder cancer studies published to date. The FACT-VCI, instrument of application limited to unique therapeutic options within the spectrum of the disease. The EORTC QLQ-NMIBC24, widely acceptable questionnaire in the European community due to its psychometric characteristics. The BUSS evaluates the patient regardless the stage of the disease. The FACT-BL evaluates life quality in patients with non-muscle invasive bladder cancer. CONCLUSION: The use of validated instruments such as: BCI, EORTC QLQ-NMIBC24, FACT-VI, BUSS and FACT-BL which allow evaluating the impact of disease and the established therapies, is recommended.

RESUMO

PURPOSE: Several factors determine the success of extracorporeal shockwave lithotripsy (SWL) for kidney stones: stone size, stone location within the collecting system, stone type, and the SWL machine used. It has been suggested that stone radiodensity, as determined either by plain radiography or computed tomography attenuation values, may be an independent predictor of SWL success. We examined the outcome of SWL for solitary stones less than or equal to 2 cm located within the renal pelvis, based on their radiodensity. MATERIAL AND METHODS: 211 patients with solitary renal pelvic stones measuring less than or equal to 2 cm were treated on a Dornier Doli 50 lithotriptor under general anesthesia. The radiodensity of the stone was determined to be either less than, equal to, or greater than the radiodensity of the ipsilateral 12th rib. Stone-free rates (SFR) were determined at 3 months by kidney, ureters and bladder (KUB) plain X-rays. Patients requiring re-treatment or auxiliary procedures were considered failures of SWL. RESULTS: Follow-up SFR information was available in all 211 patients. Stone composition was available in 158 (75%) treated patients, but no correlation was found between stone radiodensity and stone composition. For stones < or = 10 mm within the renal pelvis, the SFRs were similar (71 to 74% regardless of stone radiodensity). For stones between 11 and 20 mm, the SFR was 60% if the stone had a radiodensity > 12th rib compared to a SFR of 71% if the stone radiodensity was < or = 12th rib. However, these differences in SFRs were not statistically significant. CONCLUSIONS: On the Doli machine, stone radiodensity alone does not predict lithotripsy treatment outcome for stones < or = 1 cm within the renal pelvis. This parameter is probably only useful as the stone size becomes larger than 1 cm, and should be used in conjunction with other stone parameters to select appropriate therapy.
