Abstract Modern psychometric methods allow for cocalibration of cognition across cross-national surveys, given the presence of common tests across studies. For narrow cognitive domains, there may not be common tests due to cultural and linguistic differences in testing. We developed a novel method to facilitate cocalibration that entails (1) identifying a common score across studies highly correlated with the focal domain; (2) deriving scores separately in each study for the domain of interest; and (3) applying stratified equipercentile equating to equate domain scores in (2) to the distribution of the common metric in (1). We tested this method by equating executive functioning in the Harmonized Cognitive Assessment Protocols (HCAP) in the US (N=3496), India (N=4096), and England (N=1273). The method preserves the rank order of executive functioning derived separately (r>0.99 in England; r>0.99 in India), while preserving between-study differences observed in general cognitive functioning. We discuss limitations and future directions.

The process of 3D printing (3DP) was patented in 1986; however, the research in the field of 3DP did not become popular until the last decade. There has been an increasing research into the areas of 3DP for medical applications for fabricating prosthetics, bioprinting and pharmaceutics. This novel method allows the manufacture of dosage forms on demand, with modifications in the geometry and size resulting in changes to the release and dosage behaviour of the product. 3DP will allow wider adoption of personalised medicine due to the diversity and simplicity to change the design and dosage of the products, allowing the devices to be designed specific to the individual with the ability to alternate the drugs added to the product. Personalisation also has the potential to decrease the common side effects associated with generic dosage forms. This Special Issue Editorial outlines the current innovative research surrounding the topic of 3DP, focusing on bioprinting and various types of 3DP on applications for drug delivery as well advantages and future directions in this field of research.

Lifestyle factors, such as alcohol intake, have placed a substantial burden on public health. Alcohol consumption is increasing globally due to several factors including easy accessibility of this addictive substance besides its legal status and social acceptability. In the US, alcohol is the third leading preventable cause of death (after tobacco, poor diet and physical inactivity) with an estimated 88,000 people dying from alcohol-related causes annually, representing 1 in 10 deaths among working adults. Furthermore, the economic burden of excess drinking costs the US around $249 billion ($191.1 billion related to binge drinking). Although men likely drink more than women do, women are at much higher risk for alcohol-related problems. Alcohol use is also considered to be one of the most common non-communicable diseases, which affects reproductive health. This review article summarizes the current knowledge about alcohol-related pathogenesis of uterine fibroids (UFs) and highlights the molecular mechanisms that contribute to the development of UFs in response to alcohol consumption. Additionally, the effect of alcohol on the levels of various factors that are involved in UFs pathogenesis, such as steroid hormones, growth factors and cytokines, are summarized in this review. Animal studies of deleterious alcohol effect and future directions are discussed as well.

American Catholicism has long adapted to US liberal institutions. Progressive Catholicism has taken the liberal values of democratic participation and human rights and made them central to its interpretation of Catholic social teaching. This chapter explores in detail the thought of David Hollenbach, S.J., a leading representative of progressive Catholicism. Hollenbach has proposed an ethical framework for an economy aimed at the common good, ensuring that the basic needs of all are met and that all are able to participate in economic life. The chapter also looks at the US Catholic bishops’ 1986 pastoral letter Economic Justice for All, which emphasizes similar themes while also promoting collaboration between the different sectors of American society for the sake of the common good.

The chapter summarizes the New Progressive Dilemma (NPD) debate, identifying three arguments from comparative welfare state and party research likely to be relevant to the relationship between immigration and welfare state retrenchment: public opinion, welfare institutions, and political parties. Alignment of anti-immigrant sentiments and welfare support varies considerably between countries, especially between the US and Europe, leading to different party incentives vis-à-vis welfare state retrenchment. The chapter introduces insights from comparative welfare state and party research to the debate, discussing inter alia, political parties in terms of welfare retrenchment, immigrants as a voter group, and cross-national variation of existing welfare institutions. It addresses the complex debates around attitudinal change caused by immigration, levels of welfare support, voting behavior, and social expenditures. Combining these strands of literature, a common theoretical framework is developed that is subsequently applied to both the US and Western European context.

Numerous claims have been made by a wide range of commentators that punk is somehow “a folk music” of some kind. Doubtless there are several continuities. Indeed, both tend to encourage amateur music-making, both often have affiliations with the Left, and both emerge at least partly from a collective/anti-competitive approach to music-making. However, there are also significant tensions between punk and folk as ideas/ideals and as applied in practice. Most obviously, punk makes claims to a “year zero” creativity (despite inevitably offering re-presentation of at least some existing elements in every instance), whereas folk music is supposed to carry forward a tradition (which, thankfully, is more recognized in recent decades as a subject-to-change “living tradition” than was the case in folk’s more purist periods). Politically, meanwhile, postwar folk has tended more toward a socialist and/or Marxist orientation, both in the US and UK, whereas punk has at least rhetorically claimed to be in favor of “anarchy” (in the UK, in particular). Collective creativity and competitive tendencies also differ between the two (perceived) genre areas. Although the folk scene’s “floor singer” tradition offers a dispersal of expressive opportunity comparable in some ways to the “anyone can do it” idea that gets associated with punk, the creative expectation of the individual within the group differs between the two. Punk has some similarities to folk, then, but there are tensions, too, and these are well worth examining if one is serious about testing out the common claim, in both folk and punk, that “anyone can do it.”

AbstractRadiation-induced skin injury (RISI) is one of the common serious side effects of radiotherapy (RT) for patients with malignant tumors. Mesenchymal stem cells (MSCs) are applied to RISI repair in some clinical cases series except some traditional options. Though direct replacement of damaged cells may be achieved through differentiation capacity of MSCs, more recent data indicate that various cytokines and chemokines secreted by MSCs are involved in synergetic therapy of RISI by anti-inflammatory, immunomodulation, antioxidant, revascularization, and anti-apoptotic activity. In this paper, we not only discussed different sources of MSCs on the treatment of RISI both in preclinical studies and clinical trials, but also summarized the applications and mechanisms of MSCs in other related regenerative fields.

Abstract Background The aim of this study was to translate and linguistically validate the U.S. National Cancer Institute’s Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE™) into Simplified Chinese for use in Singapore. Methods All 124 items of the English source PRO-CTCAE item library were translated into Simplified Chinese using internationally established translation procedures. Two rounds of cognitive interviews were conducted with 96 cancer patients undergoing adjuvant treatment to determine if the translations adequately captured the PRO-CTCAE source concepts, and to evaluate comprehension, clarity and ease of judgement. Interview probes addressed the 78 PRO-CTCAE symptom terms (e.g. fatigue), as well as the attributes (e.g. severity), response choices, and phrasing of ‘at its worst’. Items that met the a priori threshold of ≥20% of participants with comprehension difficulties were considered for rephrasing and retesting. Items where < 20% of the sample experienced comprehension difficulties were also considered for rephrasing if better phrasing options were available. Results A majority of PRO-CTCAE-Simplified Chinese items were well comprehended by participants in Round 1. One item posed difficulties in ≥20% and was revised. Two items presented difficulties in < 20% but were revised as there were preferred alternative phrasings. Twenty-four items presented difficulties in < 10% of respondents. Of these, eleven items were revised to an alternative preferred phrasing, four items were revised to include synonyms. Revised items were tested in Round 2 and demonstrated satisfactory comprehension. Conclusions PRO-CTCAE-Simplified Chinese has been successfully developed and linguistically validated in a sample of cancer patients residing in Singapore.

SynopsisThis study uses methods of latent trait analysis to examine the relationships between psychiatric symptoms that constitute the common psychiatric disorders encountered in primary-care settings. Two highly correlated symptom dimensions of anxiety and depression are shown to underlie these disorders. Neurovegetative sysmptoms of depression are shown to be on the same dimension as psychic symptoms of depression, but to represent a more severe manifestation of depression.

It is beneficial to reflect on the research literature of emerging communication technology and what has been studied so far, given the rapid growth of this area of research. This study conducted a content analysis of the published literature related to emerging communication technology over a period of 16 years from 1998 to 2013. An exhaustive sample was gathered using two methods of sampling: all Institute for Scientific Information (ISI)-listed communication journals and key word searches. The study examined the common patterns in theoretical, methodological, and technological variables. The primary findings reveal a lack of theory, fuzziness in the conceptualization of the research, growth in empirical research methods, frequent use of nonprobability sampling methods, and growth in studies on blogs, social networking sites (SNS), and mobile technology. Implications and future directions are discussed.
