RESUMO

Background: As a type of welfare technology, care robotics is now widely seen as a potential aide to rehabilitation, increasing independence and enhancing the wellbeing of people with disabilities and older adults. Research into and development of care robots have both been vigorously promoted in North America, Europe and Asia, and the competition for technological advancement in robotics is becoming fierce. AI ethics and policy guidelines are being established. However, there are still differences in attitudes and perceptions, as well as national policies regarding this type of welfare technology. Moreover, despite the anticipated usefulness, it is believed that progress has been slow in the diffusion of care robots. Purpose: In order to explore how public discourses support technological innovation, such as care robots, while preparing society for potential risks and impact, we sought to ascertain whether public discourse on care robots varies from region to region. For example, what are the hopes and promises associated with care robots and what are the concerns? Methods: To address these questions, this article explored how care robots have been portrayed in five major broadsheet newspapers in five jurisdictions in Asia and Europe (France, Great Britain, Hong Kong SAR, Ireland and Japan). We obtained 545 articles for the period between January 2001 and September 2020, more than half of which originated in Japan. A thematic analysis was conducted of these articles written in four languages (Chinese, English, French and Japanese). Results: Positive and negative narratives were teased out, alongside other key prominent themes identified, such as Japan as the land of robots, the pandemic, and the impact of robots on the economy. As the number of robot-related articles grew from the year 2012 onwards, narratives became more nuanced in European newspapers, but not in Asian ones. Furthermore, recent articles began to address the social and relational impact of care robots, while providing concrete examples of improvements in the quality of life for users. Further careful examination will be necessary in the future in order to establish the impact of robotics use in rehabilitation for people with disabilities, older adults, their carers and society at large.

RESUMO

BACKGROUND AND AIMS: Low serum albumin level is reportedly associated with worse clinical outcomes in patients with chronic kidney disease (CKD). However, associations between decreased serum albumin level and outcomes in non-CKD patients with coronary artery disease (CAD) remain unclear. Therefore, we aimed to evaluate the prognostic value of serum albumin concentrations in stable CAD patients with preserved renal function. METHODS AND RESULTS: We studied 1316 patients with CAD and preserved renal function (estimated glomerular filtration rate ≥60 mL/min/1.73 m2) who underwent their first PCI between 2000 and 2011 and had data available for pre-procedural serum albumin. Patients were assigned to quartiles based on pre-procedural albumin concentrations. The incidence of major adverse cardiac events (MACE), including all-cause death and non-fatal myocardial infarction, was evaluated. Mean albumin concentration was 4.1 ± 0.4 g/dL. During the median follow-up of 7.5 years, 181 events occurred (13.8%). Kaplan-Meier curves revealed that patients with decreased serum albumin concentrations showed a higher event rate for MACE (log-rank, p < 0.0001). Using the highest tertiles (>4.3 g/dL) as reference, adjusted hazard ratios were 1.97 (95% CI, 1.12-3.55), 1.77 (95% CI, 0.99-3.25), and 1.19 (95% CI, 0.68-2.15) for serum albumin concentrations of <3.9, 3.9-4.0, and 4.1-4.3 g/dL, respectively. Decreased serum albumin concentration was associated with MACE even after adjusting for other independent variables (HR, 2.21 per 1-g/dL decrease; 95% CI, 1.37-3.56, p = 0.001). CONCLUSION: Decreased serum albumin concentration independently predicted worse long-term prognosis in non-CKD patients after PCI. Pre-procedural serum albumin concentration could offer a useful predictor for patients with CAD and preserved renal function.

RESUMO

UNLABELLED: The optimal strategy in neonatal screening for congenital hypothyroidism is still a subject of controversy. In Kanagawa Prefecture in Japan, simultaneous thyroid-stimulating hormone (TSH) and T4/fT4 determination has been used, while the results of our program may provide valuable information. Cumulative findings were analysed to determine the type and frequency of thyroid disorders in infants detected by simultaneous TSH and T4/fT4 determination, and the TSH and T4/fT4 screening strategy was validated. A total of 1284130 neonates were screened between October 1979 and September 1997 and infants followed because of low T4/fT4 without elevated TSH (T4 < 51.5 nmol/L or fT4 < 9 pmol/L and TSH < 15 mU/L) were retrospectively analysed. The first survey was carried out within 6 mo of birth and the second in 1998; 258 infants were diagnosed with congenital hypothyroidism at the first medical evaluation, 15 of them with hypothalamo-pituitary hypothyroidism. However, in the second survey, only 8 children were confirmed as having hypothalamo-pituitary hypothyroidism, therefore the incidence detected by the present strategy was 1/160516. Of 8 children with hypothalamo-pituitary hypothyroidism, mental retardation was prevented in 3 owing to early treatment. CONCLUSIONS: Simultaneous measurement of TSH and T4/fT4 is a useful strategy for detecting hypothalamo-pituitary hypothyroidism, but more studies are needed to show the cost-benefits of using this strategy.

RESUMO

OBJECTIVES: The incidence and severity of coronary artery disease were studied in patients with acute aortic dissection (AAD), and compared with coronary artery disease in patients with abdominal aortic aneurysm (AAA) or arteriosclerosis obliterans (ASO). METHODS: A total of 71 patients(42 males, 29 females, mean age 61.4 +/- 10.0 years) with AAD, undergoing coronary angiography between 1988 and 1999, were studied including 38 patients with open communication type and 33 patients with thrombosed type. According to the Stanford classification, 18 patients were type A and 53 patients were type B. Patients with AAD following Marfan syndrome or chest trauma were excluded from the study. Selective coronary angiography was performed in age- and sex-matched patients with AAA(n = 57; 42 males, 15 females, mean age 63.9 +/- 4.6 years) or ASO (n = 95; 66 males, 29 females, mean age 62.4 +/- 9.4 years). Coronary artery disease was defined as > or = 75% stenosis (left main trunk lesion of > or = 50% stenosis) by multidirectional imaging. RESULTS: Significant coronary artery disease was demonstrated in 14 patients with AAD (19.7%), 25 patients with AAA (43.9%), and 49 patients with ASO (51.5%). The incidence of coronary artery disease was significantly lower in the AAD group than in the other two groups (p < 0.05). One-vessel disease was present in approximately 70% of the patients with AAD and coronary artery disease. In contrast, multivessel disease was observed in approximately 50% of patients with AAA and ASO. Classification of the patients with AAD according to the blood flow in the false lumen showed coronary artery disease was more highly associated with the thrombosed type [10 (30.3%) of 33 patients] than the open communication type [4 (10.5%) of 38 patients]. Multivariate logistic regression analysis of the patients with AAD showed coronary artery disease was associated with a high serum total cholesterol level (p = 0.025) and the thrombosed type (p = 0.043). CONCLUSIONS: The incidence of coronary artery disease was significantly lower among patients with AAD than among age- and sex-matched patients with AAA or ASO. Coronary artery disease developed in 30% of the patients with the thrombosed type of AAD, although the prognosis seemed to be good.

RESUMO

X-linked hypophosphatemic rickets (XLH) is an X-linked dominant disorder characterized by renal phosphate wasting, abnormal vitamin D metabolism, and defects of bone mineralization. The phosphate-regulating gene on the X-chromosome (PHEX) that is defective in XLH has been cloned, and its location identified at Xp22.1. It has been recognized to be homologous to certain endopeptidases. So far, a variety of PHEX mutations have been identified mainly in European and North American patients with XLH. To analyze the molecular basis of four unrelated Japanese families with XLH, we determined the nucleotide sequence of the PHEX gene of affected members. We detected a new nonsense mutation (R198X) in exon 5, a new 3 nucleotides insertion mutation in exon 12 and a new missense mutation (L160R) in exon 5 as well as a previously reported nonsense mutation in exon 8 (R291X). These results suggest that: 1) PHEX gene mutations are responsible for XLH in Japanese patients, and 2) PHEX gene mutations are heterogeneous in the Japanese population similarly to other ethnic populations.

RESUMO

Pseudohypoaldosteronism type 1 (PHA1) is a rare condition characterized by neonatal salt loss with dehydration, hypotension, hyperkalemia, and metabolic acidosis, despite elevated plasma aldosterone levels and PRA. Two modes of inheritance of PHA1 have been described: an autosomal dominant form and an autosomal recessive form. An autosomal recessive form manifests severe life-long salt wasting resulting from multiple mineralocorticoid target tissue such as sweat, salivary glands, the colonic epithelium, and lung. Contrary, an autosomal dominant PHA1 manifests milder salt wasting that gradually improves with advancing age. Recently, in one sporadic and four dominant cases, four different mutations including two frame shift mutations, two premature termination codons, and one splice site mutation in the mineralocorticoid receptor (MR) gene were identified. We studied the molecular mechanisms of one Japanese family with a renal form of PHA1. PCR and direct sequencing of the MR gene identified a heterozygous point mutation changing codon 924 Leu (CTG) to CCG (Pro) (L924P) in all affected members. COS-1 cells were transfected with expression vectors for either wild type or the mutant MR-L924P receptors, together with the reporter plasmid (glucocorticoid response element tk-CAT). Aldosterone increased CAT activity in cells expressing wild-type receptor, but had no effect in cells expressing the mutant receptors. These results suggest that mineralocorticoid resistance in this family is due to a missense mutation in the MR gene. To our knowledge, this is the first case of the missense mutation of the MR gene in renal PHA1.

RESUMO

We report the case of a 17-year-old boy with delayed puberty, who presented a complexity of clinical problems. An analysis of steroid hormones led to a diagnosis of 17alpha-hydroxylase/17,20-lyase deficiency (17OHD). Unlike typical cases of 17OHD, however, the patient had pubertal development without medical intervention. In addition, he never exhibited the symptoms of mineralocorticoid excess, showing instead the symptoms of glucocorticoid deficiency, including fatigability, emaciation, and weight-loss induced by minor infection. He also had dysmorphic features, which comprised marfanoid habitus, arachnodactyly and putative craniosynostosis. The combination of these malformations substantially resembled that of Shprintzen-Goldberg syndrome. Direct sequencing of the CYPl7 gene did not reveal any significant aberrations in the exons or exon-intron boundaries. We speculate that the association of partial combined 17OHD with the Shprintzen-Goldberg phenotype in the present patient may result from an aberration of a hitherto unknown gene that controls both steroid hormone synthesis and skeletal development.

RESUMO

Positive responses to head-up tilt testing occur in healthy subjects. However, the reproducibility of "false-positive" tilt testing results has not been clarified. To study the reproducibility of "false-positive" responses, we prospectively performed 2 tilt tests separated by 1 to 10 (mean 3.2) weeks in 20 healthy males aged 23 to 40 years (mean 30 years). The baseline tilt test (80 degrees for 30 minutes) ended positive in 4 (20%) subjects on the initial test and 2 (10%) on the second test with only 1 (5%) who had consecutive positive responses. No additional positive responses were noted during the isoproterenol (0.01 microgram/kg/min)-tilt test for 10 minutes. We demonstrated that a false-positive response occurred in 5 (25%) of 20 young males who underwent 2 tilt tests, however, only 1 (5%) subject had consecutive positive responses. Poor reproducibility may be characteristic of false-positive responses in head-up tilt testing.

RESUMO

UNLABELLED: The phenotypes of chromosomal 22q11.2 microdeletion are quite variable among individuals and hypoparathyroidism (HP) constitutes a definite portion of the clinical spectrum. For the correct diagnosis and pertinent follow up of the HP children due to del22q11.2, we tried to delineate the clinical characteristics of such patients. By employing fluorescence in situ hybridization (FISH) to all the patients diagnosed as HP in our clinic, ten possessed the 22q11.2 microdeletion. Among them, the incidence of cardiac defect (5/10), recurrent infection (1/10) and cleft palate (1/10) was modest. Additionally, seven of them had been diagnosed as HP during the infantile period, when their facial abnormality and intellectual problem had not become evident. Notably, two patients were complicated by Graves disease, while the association of idiopathic thrombocytopenic purpura was also observed in two girls. CONCLUSION: HP due to del22q11.2 may be misdiagnosed as idiopathic, especially in an infant who lacks apparent complications like cardiac anomaly. They should be closely followed up for auto-immune complications.

RESUMO

Several authors have reported cases of patients with malignant lymphoma with unique characteristics, designated nasal-type T/NK cell lymphoma, which expresses the natural killer (NK) cell marker and shows frequent extra-nodal involvement and poor prognosis. We report 2 cases of this type of lymphoma which were CD56-positive and showed a histopathologically angiocentric pattern with cutaneous and subcutaneous tumorous lesions. Patient 1 had extensive invasion of skin, underlying skeletal muscle, spleen and bone marrow, and died of sepsis 34 months after onset. Patient 2 had multiple subcutaneous nodules and invasion to mammary gland, lung, lymph node and spleen at the time of her first visit. She died of a rapid invasion of lymphoma cells to the liver 5 months after onset. Both patients showed similar immunophenotypes of tumor cells (CD2+, CD3-, CD4-, CD8-, CD20-, CD56+) and germ line configuration of the heavy chain of immunoglobulin (JH), T-cell receptor C beta-1 subunit DNA and T-cell receptor J gamma subunit DNA. Epstein-Barr virus early regions RNA was demonstrated in the nuclei of tumor cells of both patients with in situ hybridization. The histopathological examination of the skin lesions of both patients revealed the features of angiocentric lymphoma. The detection of CD56 in the tumor cells of cutaneous lymphomas should be routinely performed for the early diagnosis of this type of lymphoma with extremely poor prognosis.

RESUMO

Congenital lipoid adrenal hyperplasia (lipoid CAH) is the most severe form of CAH in which the synthesis of all gonadal and adrenal cortical steroids is markedly impaired. We report here the clinical, endocrinological, and molecular analyses of two unrelated Japanese kindreds of 46,XX subjects affected with lipoid CAH who manifested spontaneous puberty. Phenotypic female infants with 46,XX karyotypes were diagnosed with lipoid CAH as newborns based on a clinical history of failure to thrive, hyperpigmentation, hyponatremia, hyperkalemia, and low basal values of serum cortisol and urinary 17-hydroxycorticosteroid and 17-ketosteroid. These patients responded to treatment with glucocorticoid and 9alpha-fludrocortisone. Spontaneous thelarche occurred in association with increased serum estradiol levels at the age of 10 and 11 yr, respectively. Pubic hair developed at the age of 12 yr 11 mo in one subject and menarche was at the age of 12 yr in both cases. Both subjects reported periodic menstrual bleeding and subsequently developed polycystic ovaries. To investigate the molecular basis of the steroidogenic lesion in these patients, the StAR gene was characterized by PCR and direct DNA sequence analyses. DNA sequence analysis revealed that one patient is homozygous for the Gln 258 Stop mutation in exon 7 and that the other patient is a compound heterozygote with the Gln 258 Stop mutation and a single A deletion at codon 238 in the other allele causing a frame-shift, which renders the StAR protein nonfunctional. These findings demonstrate that ovarian steroidogenesis can be spared to some extent through puberty when the StAR gene product is inactive. This is in marked contrast to the early onset of severe defects in testicular and adrenocortical steroidogenesis which are characteristics of this disease.

RESUMO

We report here a new variant of human malaria parasite found by comparison of diagnostic results obtained from a new DNA diagnostic method named microtiter plate-hybridization (MPH) and traditional microscopic method. Total five cases of malaria were diagnosed as microscopy-positive but MPH-negative; one case was found in epidemiological research in Vietnam and four cases were obtained from imported malaria in Japan. Although they were quite similar to typical P. ovale morphologically in microscopy, sequence analysis of PCR-amplified DNA fragment revealed that their 18S ribosomal RNA gene sequence was different from published sequence of P. ovale. Combination of MPH and microscopic examination provides us a new method for detection of a new type of malaria parasite which is difficult to distinguish morphologically.

RESUMO

A boy with psychosocial short stature who has been followed up from the age of 11 months to adulthood is described. The boy was the product of an unwanted pregnancy. The emaciated short boy gained weight and height markedly during a short-term stay at hospital, but lost weight and experienced minimal height gain at home. On the fourth hospital admission at the age of 6 years 3 months the boy weighed 10 kg and measured 85.7 cm, he was malnourished and exhibited strange behavior and had a voracious appetite. He was examined endocrinologically and provocative tests performed early after admission showed insufficient growth hormone secretion, although this recovered later at a time of catch-up growth. The boy was reared in an orphanage from the age of 6 years 5 months until the age of 15 years 3 months. His growth rapidly caught up to a normal rate, his abnormal behavior disappeared, and he demonstrated an increased IQ. He attained 169.5 cm at the age of 17.5 years and possessed normal secondary sexual characteristics. After graduating from senior high school the patient has been living happily by himself without intervention from his mother, and is working in a Chinese restaurant. The impaired relationship between the boy and mother has never been restored. The record of growth and development described in this case is the longest ever reported.

RESUMO

Patients with Turner syndrome have many somatic characteristics, including short stature. We report the results of a 6-year multicentre clinical trial of recombinant human growth hormone (GH) therapy in 63 patients with Turner syndrome. Twenty-six patients received GH at a dose of 0.5 IU/kg/week, while 37 received GH, 1.0 IU/kg/week, by daily subcutaneous injection. At the start of GH treatment, there was no significant difference between the two groups in chronological age, bone age, height or growth rate. Both treatment groups showed a significant growth increase during treatment. The current mean height of the 12 patients over the age of 16 treated with GH, 0.5 IU/kg/week, is 145.1 +/- 4.7 cm, and in the 16 patients treated with GH, 1.0 IU/kg/week, is 144.0 +/- 2.2 cm. In conclusion, treatment with GH does increase final height in patients with Turner syndrome. However, further studies are needed to determine the optimum age for the initiation of GH therapy, the best dose regimen and the optimal time and manner of sex and anabolic steroid use.

RESUMO

Recently we developed a sandwich enzyme immunoassay (EIA) specific for intact molecular osteocalcin (I-OC), produced only by osteoblast cell and partially released into blood circulation, to establish a specific biochemical marker of bone formation. In order to confirm whether serum I-OC levels constitute a specific marker for bone formation and to assess the relationship between serum I-OC levels and growth response to growth hormone (GH) therapy, we measured the serum I-OC in serial serum samples using this EIA from 61 children with GH deficiency who showed significant bone growth during GH therapy. The serum I-OC levels in children with GH deficiency before GH therapy were slightly lower than those in normal children (Kanzaki S. et al., J. Clin Endocrinol Metab. 1992;75:1104-9), and had a wide distribution overlapped with the normal range. These levels were apparently increased during GH treatment; that is, in contrast to the levels of 22.9 +/- 1.5 ng/ml (mean +/- SE) before GH treatment, the levels after 1 and 2 months of GH treatment were 29.1 +/- 1.6 ng/ml and 32.5 +/- 1.8 ng/ml, respectively. However, they decreased slightly at 3 months and then they gradually rose to 37.5 +/- 2.8 ng/ml after 12 months, I-OC ratios, represented by the I-OC level at each month of GH therapy in relation to pretreatment level, correlated well with the growth response (growth velocity, growth velocity SD score and delta growth velocity SD score) after 12 months of GH treatment. Correlation coefficients of the growth velocity versus I-OC ratio at 1 and 6 months of GH treatment were 0.677 (p < 0.001, N = 58) and 0.752 (p < 0.001, N = 55), respectively. However, both IGF-I and ALP ratios represented in the same way as the I-OC ratio, correlated poorly as compared with the I-OC ratio. These results demonstrate that the change of serum I-OC levels indicates a direct and sensitive reflection of bone formation, because serum I-OC levels significantly increased with the growth response to GH therapy. The measurement of serum I-OC levels after 1 month of GH treatment may be a useful tool in predicting improved growth velocity during long-term GH therapy.

RESUMO

We report a testicular juvenile granulosa cell tumor (T-JGCT) with characteristic clinical and histopathological features. The tumor was present in the left abdominal testis of a 7-month-old infant with a 45,X/46,XY karyotype and ambiguous genitalia. Preoperatively, the infant was diagnosed as having functional testicular and ovarian elements based on elevated levels of serum testosterone and estradiol following human chorionic gonadotropin and human menopausal gonadotropin administration, respectively. Histologically, the left gonad contained a tumorous lesion composed of an admixture of cellular areas and multiple cystic follicles that had some continuity with the adjacent testicular tubules. Some tumor cells showed immunoreactivity for estradiol. The right gonad was a streak gonad containing small irregular nests of sex cord-type cells. No maturing ovarian follicle was present in either gonad. To our knowledge, this is the fifth reported case of T-JGCT with abnormal sex chromosomes, and the first case of T-JGCT confirmed to have not only the morphological but also the functional characteristics of granulosa cells.

RESUMO

To define the effect of cyproterone acetate (CPA) on statural growth, 25 girls with idiopathic precocious puberty who had been treated with CPA were studied retrospectively. The final height SDS was -1.12 +/- 1.16 (mean +/- SD). The daily CPA dose was negatively related to the final height SDS. We divided our subjects into two groups according to the daily CPA dose [low dose, 84.9 +/- 15.4 mg/m2 (n = 19) vs high dose, 135.8 +/- 17.1 mg/m2 (n = 6)]. In the low dose group, the difference of the final height SDS minus height SDS for bone age at the initiation of CPA treatment was 0.55 +/- 1.16 and final height SDS was -0.82 +/- 1.05. The final height was not significantly different from the target height in the low dose group subjects whose target heights were obtained. Since the increment of height age to the increment of bone age during the treatment was significantly less in the group needing and treated with high dose CPA, high doses of CPA may reduce growth velocity more than its suppressive effect on bone maturation. These results suggest that CPA has an effect on statural growth in girls whose clinical symptoms can be controlled with a low dose of CPA, although they have not been compared with final height in untreated Japanese girls.

RESUMO

Patients with Turner syndrome were treated with recombinant human growth hormone (GH) for 3 years. Sixty-eight patients received GH, 0.5 IU/kg/week, while 93 received GH, 1.0 IU/kg/week, by daily subcutaneous injection. Both treatment groups showed a statistically significant increase in growth during treatment. However, the higher dose increased height velocity to a significantly greater extent during the first and second year of treatment. The projected adult height was exceeded by 52 of 71 patients over the age of 14 years. Plasma insulin-like growth factor 1 levels were elevated and no remarkable advances in bone age were observed. There were no other significant changes in physical or laboratory parameters. No glucose intolerance was observed. These results indicate that GH treatment is useful for accelerating growth velocity in patients with Turner syndrome. However, further study will be required to find the most appropriate dose.
