RESUMO

The prominent form of Non-Fungible Token (NFT) is found in the gaming industry. NFT games received immense attention during the COVID-19 pandemic because of their play-to-earn model. NFT gamers can enjoy and increase their finances in their spare time. Hence, the researchers utilized Structural Equation Modeling (SEM) to investigate the intention and immersive behaviors of 1082 respondents. The modified framework from the Theory of Planned Behavior (TPB) and Hedonic Motivation System Adoption Model (HMSAM) underwent SEM tests. These theories and methods were used to analyze relationships among hypotheses and assess factors influencing NFT game engagement. The results showed that hedonic motivation produced positive and significant influences on perceived usefulness, curiosity, joy, attitude, subjective norms, and perceived behavioral control. Subjective norms significantly influenced perceived ease of use. In due course, perceived ease of use yielded positive and significant effects on perceived usefulness, joy, attitude, and perceived behavioral control. Moreover, perceived usefulness, curiosity, joy, attitude, and perceived behavioral control had significant positive effects on behavioral intention. In addition, perceived usefulness, curiosity, joy, and attitude significantly and positively affected immersion. Meanwhile, only four hypotheses were not supported by the study. These findings were translated into theoretical and managerial implications to contribute to the academe given the strong the change of behavior of users towards NFT games during the pandemic; gaming industry since they will be able to develop, improve and create a new ecosystem in the gaming space, and NFT stakeholders since they will benefit from the development that will influence this study.

RESUMO

Aims Irish haemodialysis (HD) units operate the electronic Kidney Disease Clinical Patient Management System (KDCPMS). KDCMPS is not always used as the primary electronic patient record. At this study setting, KDCPMS information accuracy has not been examined to date. This study aims to identify, characterise and quantify medication discrepancies within KDCPMS records of HD outpatients. Methods Prospective, observational study conducted on the HD unit of Tallaght University Hospital. Medicine reconciliation was conducted to identify KDCPMS discrepancies with medication review to document Drug Related Problems (DRPs). Clinical pharmacists issued recommendations to resolve DRPs. Results All KDCPMS records examined contained intentional and unintentional discrepancies (n=36). Unintentional discrepancies corresponding to 8.8 discrepancies per patient (5.13SD) was observed. One-hundred-and-forty-three DRPs were identified in 34 patients (94.4%). Sixty-five per cent (65%) of pharmacist recommendations were accepted (n=93), 22.4% rejected (n=32), 8.4% (n=12) referred to the renal multidisciplinary team (MDT) and 4.2% not actioned (n=6). Conclusion KDCPMS contains inaccuracies potentially leading to systemic error. Robust clinical governance supported by national policy is required to support KDCPMS as the primary platform for renal patients. Enhanced pharmaceutical care by specialist clinical pharmacists should be supported within national models of care for chronic disease management to improve patient outcomes.

RESUMO

BACKGROUND: Chronic kidney disease (CKD) is a risk factor for adverse drug events. The clinical significance of discordance between renal prescribing references is unknown. AIM: We determined the prevalence of potentially inappropriate prescribing (PIP) in CKD, measured agreement between two prescribing references, and assessed potential for harm consequent to PIP. DESIGN: Single-centre observational study. METHODS: A random sample of hospitalized patients with CKD were grouped according to baseline CKD stage (3, 4, or 5). Prescriptions requiring caution in CKD were referenced against the Renal Drug Handbook (RDH) and British National Formulary (BNF) to identify PIP (non-compliance with recommendations). Inter-reference agreement was measured using percentage agreement and Kappa coefficient. Potential for harm consequent to PIP was assessed by physicians and pharmacists using a validated scale. One-year mortality was compared between patients with or without PIP during admission. RESULTS: Among 119 patients (median age 73 years, 50% male), 136 cases of PIP were identified in 78 (65.5%) patients. PIP prevalence, per patient, was 64.7% using the BNF and 28.6% using the RDH (fair agreement, Kappa 0.33, P < 0.001). The majority (63.2%) of PIP cases detected exclusively by the BNF carried minimal or no potential for harm. PIP was not significantly associated with one-year mortality (34.7% vs. 21.1%, P = 0.14). CONCLUSIONS: PIP was common in hospitalized patients with CKD. Substantial discordance between renal prescribing references was apparent. The development of universally-adopted, evidence-based, prescribing guidelines for CKD might optimize medications safety in this vulnerable group.

RESUMO

PIP: This preliminary study explored the impact on women of economic migration from rural to urban areas in China. Data were obtained from the 1990 census. The study focused on economic migration, which accounted for 29% of the reasons for moving. In some provinces such as Guangdong, economic reasons account for almost 60% of in-migrants. Interprovincial migration is primarily economic, followed by marriage, which varies widely by province. Migrants tend to assume occupations that are assigned by gender. Male migrants tend to outnumber female migrants, and women are left to farm. Where migration is gender balanced, the sex ratio in the sending area may be stable, but gender division within individual households is upset. Children may be tended by grandparents in rural areas, when their parents find work in cities. Migrants in urban areas do not have the same rights as permanent urban household registrants and cannot send their children to school or use free or low cost health care. Migrants keep in close contact with home villages. Urban migrants without permanent household registration status face the loss of welfare benefits in urban areas as well as the high cost of purchase of a permanent residence permit, social discrimination, stigma from mass media portrayals, and poor housing. Most rural-urban migration is circular. Female return migrants bring back cash remittances and new family roles and status. Rural migrants are exposed to new urban experiences that are retold in rural areas and that may pose difficulties in readjustment to the hardships of rural life. Urban fertility is delayed and lower than that of rural fertility.^ieng

RESUMO

PIP: Many men and women in China are migrating in search of better economic opportunities. Young women who migrate to urban centers in search of opportunity may stay away from their home villages for several years. At some point, however, they are likely to return home. This article considers the effect which such circular migration is having upon gender relations in China. The author's argument is presented in sections on China's 1990 census, migration and the sexual division of labor, migration and child care, the influence of returning migrants, the influence of young female returnees, and the fertility of returnees. She speculates that the demands and expectations of young women who return to their villages after spending some time earning high wages in urban areas will be affected by urban norms. While their return may lead to initial conflict, it is likely that the women will retain greater personal autonomy from their urban experience. Their return is also likely to lead to a higher degree of material consumption in the rural areas. Present circular migration in China has the potential to return human and financial resources to the villages, thereby helping to prevent the urban-rural gap between economic, social, cultural, and educational factors from growing even wider.^ieng

RESUMO

Partial hepatectomy (PH) in rats induces a synchronized burst of DNA replication in the remnant liver that peaks at 24 h post-PH. We report here that removal of the major salivary glands before one-third and two-thirds PH prevents the proliferative response in the remaining liver. Twelve days after one-third PH, the remnant liver is 89% of the normal liver weight in nonsalivectomized rats but only 55% in salivectomized animals. This indicates that salivectomy does not merely delay the first round of cell division but that it prevents actual regeneration. Salivectomy alters the early protooncogene response to partial hepatectomy. In salivectomized rats, the characteristic peak of c-myc mRNA synthesis at 2-4 h after PH is significantly decreased compared with nonsalivectomized rats. The peak of DNA synthesis at 24 h after PH in salivectomized rats is also dramatically decreased. DNA synthesis as measured by [3H]thymidine incorporation into DNA of hepatic cells is decreased approximately 90% in salivectomized rats vs. nonsalivectomized rats 22-26 h after PH. Ligation of the venous drainage of the salivary gland results in the same inhibitory effect on DNA synthesis, indicating 1) that the salivary gland must release circulating factor(s), and 2) that the early increase in c-myc expression and the subsequent DNA synthesis, both of which reflect the stimulation of cellular proliferation in the regenerating liver, are induced by humoral factor(s) released from the salivary glands. Injection of exogenous epidermal growth factor (EGF) in salivectomized rats results in restoration of both the DNA synthetic and c-myc responses at levels characteristic of those of liver regeneration.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

Expression of the c-myc and c-Ha-ras protooncogenes is dramatically increased in regenerating rat liver as an early response to partial hepatectomy. Nuclear runon transcription studies confirm that the increased c-myc and c-Ha-ras mRNA levels in regenerating livers reflect transcriptional activation of these genes. Mithramycin, a G-C specific DNA binding drug, prevents the increased transcriptional activity of c-myc and c-Ha-ras genes after hepatectomy but does not alter the transcriptional activity of the beta-actin gene. Continuous exposure of rats to mithramycin after hepatectomy prevents the increase in both c-myc and c-Ha-ras expression and blocks the increased cellular proliferation characteristic of regeneration. The delayed increase in c-myc and c-Ha-ras gene expression is associated with a delay in cellular proliferation. The inhibition of c-myc and c-Ha-ras transcription by mithramycin, the delay in cellular proliferation, and the ability of mithramycin to prevent protein binding to the c-myc promoter, suggest that the increased expression of these genes is a necessary component of liver regeneration.

RESUMO

Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) are responsible for cystic fibrosis. The CFTR gene has recently been identified and encodes a 6.5-kb mRNA transcript. Recent observations showing that CFTR expression increases during differentiation of epithelial cells suggested that CFTR may also be regulated in the liver in response to partial hepatectomy (PH). We studied the expression of CFTR in rat regenerating liver and investigated the mechanisms that regulate CFTR RNA levels during a 120-h period after PH. Northern and slot-blot analysis revealed a liver-specific biphasic increase of CFTR mRNA levels, which peaks at 2 and 24 h post-PH. In contrast to these findings, the mode of regulation of the homologous gene MDR-1 showed a clearly different pattern. Nuclear run-on analysis demonstrated increased levels of CFTR transcription corresponding to the time points where an increase in CFTR message was observed. Similarly, the beta-actin gene, which increases transiently during liver regeneration, showed increased nuclear run-on activity 4 h posthepatectomy, indicating that the nuclei were functional. No increase of MDR-1 gene transcription was detected, confirming the previous finding that the increase in MDR-1 mRNA level in regenerating liver results from a post-transcriptional event such as message stabilization. This study indicates that expression of the CFTR gene is regulated during the regenerative process of the liver. The data also suggest that the increase in CFTR and MDR expression levels result from two distinct regulatory mechanisms.

RESUMO

In 101 patients with non-familial cutaneous melanoma (CM), melanocytic naevi were counted and classified according to clinical criteria. Only 8% of the patients had very atypical naevi. These atypical naevi were few in number and only one patient exhibited dysplastic naevus syndrome. An histological study was undertaken on the hypothesis that, in a given individual, if the most clinically atypical naevus is not histologically dysplastic it is unlikely that any of the others are. The most clinically atypical naevus in each patient was biopsied. Estimated in this way the prevalence of dysplastic naevi in patients with non-familial CM was only 18%. Comparison of patients with and without dysplastic naevi did not suggest that they constituted two different subsets. An attempt to correlate clinical diagnosis and histological features in this group of patients showed that the diagnosis of dysplastic naevi on the basis of clinical criteria alone is difficult and not reliable.
