RESUMEN

Wisdom is the hallmark of social judgment, but how people across cultures recognize wisdom remains unclear-distinct philosophical traditions suggest different views of wisdom's cardinal features. We explore perception of wise minds across 16 socio-economically and culturally diverse convenience samples from 12 countries. Participants assessed wisdom exemplars, non-exemplars, and themselves on 19 socio-cognitive characteristics, subsequently rating targets' wisdom, knowledge, and understanding. Analyses reveal two positively related dimensions-Reflective Orientation and Socio-Emotional Awareness. These dimensions are consistent across the studied cultural regions and interact when informing wisdom ratings: wisest targets-as perceived by participants-score high on both dimensions, whereas the least wise are not reflective but moderately socio-emotional. Additionally, individuals view themselves as less reflective but more socio-emotionally aware than most wisdom exemplars. Our findings expand folk psychology and social judgment research beyond the Global North, showing how individuals perceive desirable cognitive and socio-emotional qualities, and contribute to an understanding of mind perception.

RESUMEN

AIMS: There is a need for the adequate distribution of healthcare resources in Southeast Asia. Many countries in the region have more patients with advanced breast cancer who are eligible for postmastectomy radiotherapy (PMRT). Therefore, it is critical that hypofractionated PMRT is effective in most of these patients. This study investigated the significance of postoperative hypofractionated radiotherapy in patients with breast cancer, including advanced breast cancer, in these countries. MATERIALS AND METHODS: Eighteen facilities in 10 Asian countries participated in this prospective, interventional, single-arm study. The study included two independent regimens: hypofractionated whole-breast irradiation (WBI) for patients who had undergone breast-conserving surgery and hypofractionated PMRT for patients who had undergone total mastectomy at a dose of 43.2 Gy in 16 fractions. In the hypofractionated WBI group, patients with high-grade factors received additional 8.1 Gy boost irradiation sessions for the tumour bed in three fractions. RESULTS: Between February 2013 and October 2019, 227 and 222 patients were enrolled in the hypofractionated WBI and hypofractionated PMRT groups, respectively. The median follow-up periods in the hypofractionated WBI and hypofractionated PMRT groups were 61 and 60 months, respectively. The 5-year locoregional control rates were 98.9% (95% confidence interval 97.4-100.0) and 96.3% (95% confidence interval 93.2-99.4) in the hypofractionated WBI and hypofractionated PMRT groups, respectively. Regarding adverse events, grade 3 acute dermatitis was observed in 2.2% and 4.9% of patients in the hypofractionated WBI and hypofractionated PMRT groups, respectively. However, no other adverse events were observed. CONCLUSION: Although further follow-up is required, hypofractionated radiotherapy regimens for postoperative patients with breast cancer in East and Southeast Asian countries are effective and safe. In particular, the proven efficacy of hypofractionated PMRT indicates that more patients with advanced breast cancer can receive appropriate care in these countries. Hypofractionated WBI and hypofractionated PMRT are reasonable approaches that can contain cancer care costs in these countries. Long-term observation is required to validate our findings.

RESUMEN

BACKGROUND: In young patients with localized prostate cancer, radical prostatectomy is the treatment of choice in the general population. Radiotherapy, such as low-dose rate (LDR) brachytherapy or intensity-modulated radiotherapy, is a viable alternative as well. However, in transplant patients, irradiation is not proposed as often as it is in healthy adults because of the risk of post-radiation ureteral stenosis and gastrointestinal toxicity as the result of fragile tissue. The objective of the study was to assess the efficacy and feasibility of LDR brachytherapy for prostate cancer in renal transplant recipients (RTRs). METHODS: Between May 2007 and December 2014, all patients who had undergone LDR brachytherapy for clinically localized prostate cancer at our institution were retrospectively identified (n = 203). Of these patients, 2 had a history of renal transplantation. We reviewed all available clinical data retrospectively. One patient had a functioning graft and the other had re-started hemodialysis 7 years after the transplantation. RESULTS: The mean time from renal transplantation to prostate cancer diagnosis was 16 years. The mean follow-up after seed implantation was 45 months. There were no peri-operative complications after seed implantation. The 2 patients remained free of prostate-specific antigen progression during the follow-up period. The renal function of the patient with a functioning graft, as measured by serum creatinine, was stable during and after the operation. CONCLUSIONS: LDR brachytherapy is technically feasible and acceptable as a minimally invasive treatment in carefully selected RTRs with localized prostate cancer. This treatment should be considered a suitable option for RTRs with localized prostate cancer.

RESUMEN

BACKGROUND: In transplant patients with localized prostate cancer, irradiation is not proposed as often as it is in healthy adults because of the post-radiation risks, such as ureteral stenosis and gastrointestinal toxicity as the result of fragile tissue. The objective of the study was to analyze the efficacy and feasibility of intensity-modulated radiation therapy (IMRT) for prostate cancer in renal transplant recipients (RTRs). METHODS: Between May 2005 and December 2014, all patients who had undergone IMRT for clinically localized prostate cancer at our institution were retrospectively identified (n = 365). Of these patients, 2 had a history of renal transplantation. We reviewed all available clinical data. One patient had a functioning graft and the other had restarted hemodialysis 7 years after the transplantation. RESULTS: The mean time from renal transplantation to prostate cancer diagnosis was 11 years. The mean follow-up after irradiation was 43 months. The 2 patients remain free of prostate-specific antigen progression. There was no severe acute and chronic genitourinary and gastrointestinal toxicity. Renal function of the patient with a functioning graft as measured by serum creatinine was stable during and after the irradiation. CONCLUSIONS: IMRT is feasible and acceptable as a minimally invasive treatment in the carefully selected RTRs with localized prostate cancer. This treatment should be considered a good option for RTRs with localized prostate cancer.

RESUMEN

AIMS: Skin colonization of Staphylococcus spp. critically affects the severity of dermatitis in humans and animals. We examined different types of fatty acid salts for their antibacterial activity against Staphylococcus spp. when used in ultrapure soft water (UPSW). We also evaluated their therapeutic effect on a spontaneous canine model of dermatitis. METHODS AND RESULTS: UPSW, in which Ca(++) and Mg(++) were replaced with Na(+) , was generated using a water softener with cation-exchange resin. Staphylococcus aureus (Staph. aureus), Staphylococcus intermedius (Staph. intermedius), and Staphylococcus pseudintermedius (Staph. pseudintermedius) were incubated with various fatty acid salts in distilled water (DW) or UPSW and the number of bacteria was counted. Among the fatty acids, oleic acid salt and linoleic acid (LA) salt reduced the number of these bacteria. Also, UPSW enhanced the antibacterial effect of LA on Staph. spp. In spontaneously developed itchy dermatitis in companion dogs, shampoo treatment with liquid soap containing 10% LA in UPSW improved skin conditions. CONCLUSIONS: LA salt showed antibacterial activity against Staph. spp. Treatment with soap containing LA with UPSW reduced clinical conditions in dogs with dermatitis. SIGNIFICANCE AND IMPACT OF THE STUDY: Because colonization of Staph. spp. on the skin exacerbates dermatitis, the use of LA-containing soap in UPSW may reduce unpleasant clinical symptoms of the skin.

RESUMEN

PURPOSE: Skin toxicity caused by radiotherapy has been visually classified into discrete grades. The present study proposes an objective and continuous assessment method of skin erythema in digital images taken under arbitrary lighting conditions, which is the case for most clinical environments. The purpose of this paper is to show the feasibility of the proposed method. METHODS: Clinical data were gathered from six patients who received carbon beam therapy for lung cancer. Skin condition was recorded using an ordinary compact digital camera under unfixed lighting conditions; a laser Doppler flowmeter was used to measure blood flow in the skin. The photos and measurements were taken at 3 h, 30, and 90 days after irradiation. Images were decomposed into hemoglobin and melanin colors using independent component analysis. Pixel values in hemoglobin color images were compared with skin dose and skin blood flow. The uncertainty of the practical photographic method was also studied in nonclinical experiments. RESULTS: The clinical data showed good linearity between skin dose, skin blood flow, and pixel value in the hemoglobin color images; their correlation coefficients were larger than 0.7. It was deduced from the nonclinical that the uncertainty due to the proposed method with photography was 15%; such an uncertainty was not critical for assessment of skin erythema in practical use. CONCLUSIONS: Feasibility of the proposed method for assessment of skin erythema using digital images was demonstrated. The numerical relationship obtained helped to predict skin erythema by artificial processing of skin images. Although the proposed method using photographs taken under unfixed lighting conditions increased the uncertainty of skin information in the images, it was shown to be powerful for the assessment of skin conditions because of its flexibility and adaptability.

RESUMEN

Telomerase participates in malignant transformation or immortalization of cells, and has attracted attention as an anticancer drug screening and diagnostic tumor marker. We developed a novel telomerase assay called the PPDK-luciferin-luciferase system bioluminescence assay (PLLBA) using pyruvate phosphate dikinase (PPDK). In this assay, pyrophosphate produced by the telomerase reaction and polymerase chain reaction (PCR) is converted to ATP by PPDK, and ATP is detected by the firefly luciferin-luciferase reaction. In this work, telomerase substrate was obtained in accordance with the telomeric repeat amplification protocol (TRAP). Telomerase-positive (500 cells/assay), -inactive (heated for 10 min at 85 °C) and -negative (only Chaps lysis buffer) samples were used. As a result, the findings clearly showed that the signal-to-noise (S/N) ratio of the positive cells was 39.5. After the telomerase reaction and PCR, PLLBA was completed ~ 120 s later. A high level of reproducibility was obtained with - coefficient of variation (CV) of 4.1% (positive cells). The detection limit for cells using telomerase was one cell per assay. This assay for telomerase activity was also shown to be adaptable to human cancer-derived cell lines.

RESUMEN

Lymphoid neoplasms including lymphoma and leukemia are one of the most life-threatening disorders in dogs. Many lymphoid malignancies are well-treated with glucocorticoid (GC); however, GC resistance sometimes develops and its mechanism remains uncertain. Since constitutive activation of nuclear factor-κB (NF-κB) has been reported to play roles in lymphoid malignancies, we examined whether inhibition of NF-κB activity with a synthetic inhibitor IMD-0354 affected GC sensitivity of canine neoplastic lymphoid cells, CL-1 and GL-1. Dexamethasone failed to inhibit proliferation of these cells, in which low expression of glucocorticoid receptors (GR) was identified. In the presence of IMD-0354, GR expressions in CL-1 and GL-1 were increased, consequently dexamethasone inhibited their proliferation. These results indicated that GR expression might be down-regulated by spontaneous activation of NF-κB, resulting in GC resistance. Taken together, interference of NF-κB activity may have the synergistic effect in combination chemotherapy with GC for treatment against lymphoid malignancies.

RESUMEN

A 10-year-old female West Highland white terrier was presented with refractory hyperplastic keratitis of the left cornea of one month's duration. At this time, a vascularised and rough lesion 5 mm in diameter was observed on the left cornea. No other abnormality was recognised on the affected eye. The corneal neoplasm was surgically removed and histologically diagnosed as a squamous cell carcinoma. For two months after the surgery, 0.04 percent mitomycin C (MMC) eye drops were applied as adjuvant chemotherapy. Primary corneal squamous cell carcinoma with no history of keratoconjunctivitis sicca is rare in dogs. In the present report, surgical removal of the neoplasm was combined with the topical administration of the anticancer drug mitomycin C and a good prognosis was obtained. The result indicates that the combination treatment used in this case may be an appropriate therapeutic choice for corneal squamous cell carcinoma in dogs.

RESUMEN

We report the case of a patient with invasive uterine cervical carcinoma, who is also infected with human immunodeficiency virus. This patient has had the longest progression-free survival of any with acquired immunodeficiency syndrome uterine cervical carcinoma. She was found to be human immunodeficiency virus positive in February 1996 and found to have uterine cervical carcinoma stage IB in July 1996. Shortly thereafter, she underwent radiation therapy. She died of renal and liver failure in January 1999. However, no residual tumor existed at that time. The longest progression-free survival in this case may be attributable to maintenance of the CD4 cell count from the onset of uterine cervical carcinoma to death, which meant the patient's immune system to the cancer cells worked.

RESUMEN

OBJECTIVE: To investigate whether transthoracic Doppler echocardiography (TTE) can reliably measure the coronary flow reserve in the left anterior descending coronary artery in children with Kawasaki disease. DESIGN: Coronary flow velocity in the distal left anterior descending coronary artery was measured by TTE and was compared with that obtained by intracoronary Doppler guide wire. The ratio of maximum hyperaemia (intravenous administration of adenosine triphosphate, 160 microg/kg/min) to baseline peak (mean) diastolic coronary flow velocity in the distal artery was used as an estimate of coronary flow reserve. SETTING: University hospital. PATIENTS: 10 patients with significant left anterior descending coronary stenosis (> 70% diameter stenosis) (group A) in the proximal or middle portion of the artery and 14 patients (group B) without significant stenosis, all with Kawasaki disease documented by previous coronary angiography. RESULTS: The reduced hyperaemic coronary flow velocity in group A compared with group B resulted in a markedly lower coronary flow reserve, derived from both peak diastolic velocity and mean diastolic velocity by either technique of investigation. Multivariate analysis identified the best predictor of left anterior descending coronary artery stenosis to be a coronary flow reserve of < or = 2.2, derived from mean diastolic flow velocity measured using TTE (sensitivity 90%, specificity 100%, accuracy 96%). A good correlation was found between diastolic velocity derived values for coronary flow reserve measured using both TTE and Doppler guide wire (r = 0.92, p = 0.0001). CONCLUSIONS: Coronary flow reserve in the distal left anterior descending coronary artery can be accurately measured using TTE without any intravascular instrumentation in children with Kawasaki disease.

RESUMEN

BACKGROUND: This study was designed to evaluate the concomitant use of docetaxel and carboplatin for radiosensitization in head and neck cancer. MATERIALS AND METHODS: One dose of docetaxel at 10 mg/m2 and five doses of carboplatin at AUC of 0.4 per week were administered to patients during the first two weeks of radiotherapy. Sixteen patients were treated with this regimen. Radiotherapy was given to a total dose of 64.8 to 82.0 Gy. Altered fractionation radiotherapy was performed in 12 patients with untreated advanced tumors. RESULTS: The complete response (CR) rate was 81%, with a partial response (PR) rate of 19%. Toxicities included grade 3 mucositis in 69% of patients and grade 2 dermatitis in 56% of patients. CONCLUSION: This schedule of docetaxel and carboplatin combined with radiotherapy may become a useful approach for the management of head and neck cancer with proper management of mucositis.

RESUMEN

BACKGROUND AND OBJECTIVES: The combination of 5-fluorouracil and radiotherapy is thought to be the most effective treatment for locally unresectable pancreatic carcinoma. The outcomes, however, are far from acceptable from the viewpoint of long-term survival. We assessed the survival benefits of oral adjuvant chemotherapy with doxifluridine (5'-DFUR) following radiotherapy for patients with the disease. METHODS: Thirty-five consecutive patients who underwent bypass surgery and radiotherapy for localized advanced unresectable adenocarcinoma of the pancreas head were retrospectively reviewed in regard to disease progression and survival. Ten of the 35 patients underwent adjuvant chemotherapy with 5'-DFUR after radiotherapy in an outpatient setting. RESULTS: The 1-year survival for patients treated with radiotherapy alone was 29%. The 1-, 2-, and 3-year survivals for patients treated with the adjuvant chemotherapy after radiotherapy were 50, 40, and 30%, respectively (P = 0.0069, log-rank test). The elevation of tumor markers was delayed (P = 0.0346) and local control rate was improved (P = 0.0475) in patients with chemotherapy. Multivariate analysis demonstrated that the adjuvant chemotherapy with 5'-DFUR was a significant independent prognostic factor as well as tumor size. CONCLUSIONS: The adjuvant chemotherapy with 5'-DFUR following radiotherapy led to a significant prolongation of the survival for patients with unresectable localized pancreatic cancer.

RESUMEN

Water and raw vegetables consumed in ten nursery schools were evaluated for the presence of transmissible forms of enteroparasites. The water was submitted to filtration through membranes. The washed membrane water was submitted to the Faust method. The in natura and washed vegetables were washed and the water analyzed by the sedimentation method. Contamination was not detected in one school; in two schools, all the materials were contaminated; in four schools, two items were contaminated and in three, one material presented contamination. The water presented a contamination index of 0.7% contamination (Hymenolepis diminuta, Strongyloides stercoralis and Ancylostomatidae); the vegetables in natura, 3.9% (Strongyloides stercoralis, Ancylostomatidae, Ascaris lumbricoides and Giardia lamblia) and the washed samples 1.3% (Strongyloides stercoralis, Ascaris lumbricoides and Giardia lamblia). The water and vegetables are enteroparasites vehicles. The larval form predominated. The vegetables in natura presented higher contamination than those that were washed. Elimination of these forms in vegetables was not guaranteed by washing.

RESUMEN

A 36-year-old woman admitted to our hospital because of numbness in the left limbs and weakness in the right arm, and was subsequently given a diagnosis of intramedullary spinal cord metastases from lung cancer. The patient had lung adenocarcinoma with metastases to the brain, spine and lymph nodes. Occipital craniotomy, radiation therapy and chemotherapy were performed on the lesions in the year following June 1994. In June 1995, however, she complained of numbness in the left limbs and weakness in the right arm. Compatible with her neurological manifestation, MRI demonstrated tumors in the right side of the cord at the spinal level of C3-4 and C7-Th1, both of which were of high density in T2-enhanced conditions with enhancement by gadolinium-diethylenetriamine pentaacetic acid. No invasion from spinal metastasis was detected by CT, scintigraphy or MRI. We therefore diagnosed her manifestation as Brown-Séquard syndrome caused by intramedullary spinal cord metastatic tumors of lung adenocarcinoma. In order to avoid paraplegia and dysfunction of the bladder and bowel, radiation therapy of the cord lesions with total dose of 44 Gy was performed. Her neurologic manifestation was improved, restoring her quality of life, as the tumor size estimated by MRI decreased. Four months later, however, she died of lung adenocarcinoma that developed accompanied with severe peritonitis carcinomatosa and multiple metastases.

RESUMEN

OBJECTIVES: The severity of carotid arteriosclerosis, defined as increased intima-media thickness (IMT) visible with B-mode ultrasound, is correlated with risk factors for coronary heart disease. Little is known, however, about the relation of IMT, the stiffness of the common carotid artery, and the progression of atherosclerosis in children with Kawasaki disease (KD) and coronary artery lesions (CAL). DESIGN: We investigated the associations among total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride, TC/HDL-C, ApoE genotype, glycohemoglobin, IMT, and arterial stiffness by high resolution ultrasound in 20 adolescents with KD and CAL (age: 16.6 +/- 4.1 years, males: 60%) and 20 sex- and age-matched healthy controls (Cont). RESULTS: No significant differences were observed in the values of body mass index and blood pressure between the 2 groups. Also no significant differences were observed in the levels of TC, LDL-C, HDL-C, triglyceride, TC/HDL-C within normal values, or the allele frequency of Apo E4 between the 2 groups. However, the values of IMT, stiffness, and glycohemoglobin in patients with KD were significantly higher than those in Cont (0.53 +/- 0.07 vs 0.46 +/- 0.05 mm, P <.05; 4.11 +/- 0.86 vs 2.94 +/- 0.91, P <.001; 5.0 +/- 0.4 vs 4.6 +/- 0.2%, P <.05). A significant relationship was observed between sex and the mean IMT (r = 0.46) in Cont; however, no significant correlation was found between mean IMT and other variables in either group. Although the arterial stiffness was strongly related to body mass index (r = 0.58) and systolic blood pressure (r = 0.55) in Cont, no significant relationship was observed between the stiffness and any variable tested in patients with KD. CONCLUSIONS: The less distensible carotid wall in patients with KD compared with that in Cont without major alteration of the lipid profile is likely to be secondary to the changes in arterial walls after a diffuse vasculitis involving noncoronary arteries. These results indicate that the coronary arteries may be predisposed to accelerated atherosclerosis in patients with KD and CAL.

RESUMEN

We describe the case of a 51-year-old patient with relapsed myelodysplastic syndrome after allogeneic bone marrow transplantation (BMT), who underwent allogeneic peripheral blood stem cell transplantation (PBSCT) after conditioning with a novel regimen consisting of fludarabine, busulfan, and antithymocyte globulin. The second PBSCT was performed early, at 3 months after the initial allogeneic BMT, but it was well tolerated and complete hematologic remission was documented. The patient did not experience any early transplantation-related organ toxicity but died from opportunistic infection 6 months after the second transplantation. Our experience suggests that this novel regimen may induce remission and could be offered to patients relapsing after the first transplantation; however, the fludarabine-containing regimen might be accompanied by profound immunosuppression.

RESUMEN

Four patients had the clinical features of 'ampulla cardiomyopathy', consisting of acute-onset transient left ventricular apical akinesis with basal normokinesis, normal coronary angiogram, ST-segment elevation and subsequent giant T wave inversion, which mimicked acute coronary syndrome, the onset of which occurred shortly after extreme mental stress. Myocardial necrosis was minimal, although 2 patients showed elevated serum catecholamine levels in the acute phase. Each patient underwent serial cardiac radionuclide single-photon emission computed tomography of myocardial functional sympathetic innervation, fatty acid metabolism and perfusion using I-123-metaiodobenzyl-guanidine (MIBG), I-123-beta-metyl-iodophenyl pentadecanoic acid (BMIPP) and thallium-201 (201Tl), respectively. In the acute phase, MIBG and BMIPP imaging showed an uptake defect in the apical region, whereas 201Tl uptake was mildly decreased. When assessed semi-quantitatively, the MIBG images had higher defect scores from the acute phase throughout the year of observation compared with BMIPP, and 201Tl. These observations suggest that the primary cause of ampulla cardiomyopathy is related to a disturbance of the cardiac sympathetic innervation.

RESUMEN

This study examined reactions toward an expression of anger or guilt. Participants' reactions were assessed after their partner for a collaborative task expressed anger or guilt due to failure on the task. Analysis indicated that participants inferred the attribution of responsibility made by the partner based on the expressed emotions; anger elicited an inference that the partner attributed the failure to the participant, while guilt led to an inference that the partner attributed the failure to the self. Further, expressers of anger were perceived as having more negative traits and were avoided more than those who expressed guilt. Discussion considered negative interpersonal effect of an expression of anger.
