Data exploration using example-based methods
Data usually comes in a plethora of formats and dimensions, rendering the exploration and information extraction processes challenging. Thus, being able to perform exploratory analyses in the data with the intent of having an immediate glimpse on some of the data properties is becoming crucial. Exploratory analyses should be simple enough to avoid complicate declarative languages (such as SQL) and mechanisms, and at the same time retain the flexibility and expressiveness of such languages. Recently, we have witnessed a rediscovery of the so-called example-based methods, in which the user, or the analyst, circumvents query languages by using examples as input. An example is a representative of the intended results, or in other words, an item from the result set. Example-based methods exploit inherent characteristics of the data to infer the results that the user has in mind, but may not able to (easily) express. They can be useful in cases where a user is looking for information in an unfamiliar dataset, when the task is particularly challenging like finding duplicate items, or simply when they are exploring the data. In this book, we present an excursus over the main methods for exploratory analysis, with a particular focus on example-based methods. We show how that different data types require different techniques, and present algorithms that are specifically designed for relational, textual, and graph data. The book presents also the challenges and the new frontiers of machine learning in online settings which recently attracted the attention of the database community. The lecture concludes with a vision for further research and applications in this area.

Targeted Muscle Reinnervation
Regenerative Peripheral Nerve Interface (RPNI) and Targeted Muscle Reinnervation (TMR) have demonstrated superior outcomes compared to classical amputation in prophylactic prevention of pain, primarily by reducing the incidence of symptomatic neuromas, residual limb pain, and phantom limb pain. However, direct comparisons between these two techniques remain limited. Furthermore, their comparative effectiveness across diverse patient demographics (including age, sex, and comorbidities) and surgical variables (amputation level, etiology, and nerve handling) has not been systematically evaluated. Therefore, the objective of this systematic review and meta-analysis is to synthesize the available evidence to determine the comparative safety and efficacy of primary TMR or RPNI. This review will be conducted following the methodological guidance of the Cochrane Handbook for Systematic Reviews of Interventions. A comprehensive electronic search will be performed in the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Scopus, PubMed, and MedRxiv, without language restrictions. We will include randomized controlled trials, quasi-randomized trials, and observational studies. Study selection and data extraction will be managed using Covidence. Two reviewers will independently screen titles and abstracts, assess full-text eligibility, evaluate risk of bias, and extract data.

Targeted Muscle Reinnervation for pain prevention in patients with limb amputation: A protocol for a systematic review and meta-analysis
Introduction Regenerative Peripheral Nerve Interface (RPNI) and Targeted Muscle Reinnervation (TMR) have demonstrated superior outcomes compared to classical amputation in prophylactic prevention of pain, primarily by reducing the incidence of symptomatic neuromas, residual limb pain, and phantom limb pain. However, direct comparisons between these two techniques remain limited. Furthermore, their comparative effectiveness across diverse patient demographics (including age, sex, and comorbidities) and surgical variables (amputation level, etiology, and nerve handling) has not been systematically evaluated. Therefore, the objective of this systematic review and meta-analysis is to synthesize the available evidence to determine the comparative safety and efficacy of primary TMR or RPNI. Methods and design This review will be conducted following the methodological guidance of the Cochrane Handbook for Systematic Reviews of Interventions. A comprehensive electronic search will be performed in the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Scopus, PubMed, and MedRxiv, without language restrictions. We will include randomized controlled trials, quasi-randomized trials, and observational studies. Study selection and data extraction will be managed using Covidence. Two reviewers will independently screen titles and abstracts, assess full-text eligibility, evaluate risk of bias, and extract data. Ethics and dissemination As this systematic review relies on the analysis of secondary data from published studies, ethical approval is not required. Findings will be disseminated through publication in a peer-reviewed journal and presented at relevant conferences. PROSPERO registration number CRD42024617299

Trends in the Regulation of Per- and Polyfluoroalkyl Substances (PFAS): A Scoping Review
Products containing per- and polyfluoroalkyl substances (PFAS) have been used for decades in industrial and consumer products. These compounds are persistent in the environment, bioaccumulative, and some are toxic to humans and other animals. Since the early 2000s, laws, policies, and regulations have been implemented to reduce the prevalence of PFAS in the environment and exposures to PFAS. We conducted a scoping literature review to identify how PFAS are regulated internationally, at the U.S. national level, and at the U.S. state level, as well as drivers of and challenges to implementing PFAS regulations in the U.S. This review captured peer-reviewed scientific literature (e.g., PubMed), grey literature databases (e.g., SciTech Premium Collection), Google searches, and targeted websites (e.g., state health department websites). We identified 454 relevant documents, of which 61 discussed the non-U.S. PFAS policy, 214 discussed the U.S. national-level PFAS policy, and 181 discussed the U.S. state-level PFAS policy. The drivers of and challenges to PFAS regulation were identified through qualitative analysis. The drivers of PFAS policy identified were political support for regulation, social awareness of PFAS, economic resource availability, and compelling scientific evidence. The challenges to implementing PFAS regulations were political limitations, economic challenges, unclear scientific evidence, and practical challenges. The implications for PFAS policy makers and other stakeholders are discussed.

Preliminary guideline for reporting bibliometric reviews of the biomedical literature (BIBLIO): a minimum requirements
Background
A bibliometric review of the biomedical literature could be essential in synthesizing evidence if thoroughly conducted and documented. Although very similar to review papers in nature, it slightly differs in synthesizing the data when it comes to providing a pile of evidence from different studies into a single document. This paper provides a preliminary guideline for reporting bibliometric reviews of the biomedical literature (BIBLIO).
Methods
The BIBLIO was developed through two major processes: literature review and the consensus process. The BIBLIO started with a comprehensive review of publications on the conduct and reporting of bibliometric studies. The databases searched included PubMed, Scopus, Web of Sciences, and Cochrane Library. The process followed the general recommendations of the EQUATOR Network on how to develop a reporting guideline, of which one fundamental part is a consensus process. A panel of experts was invited to identify additional items and was asked to choose preferred options or suggest another item that should be included in the checklist. Finally, the checklist was completed based on the comments and responses of the panel members in four rounds.
Results
The BIBLIO includes 20 items as follows: title (2 items), abstract (1 item), introduction/background (2 items), methods (7 items), results (4 items), discussion (4 items). These should be described as a minimum requirements in reporting a bibliometric review.
Conclusions
The BIBLIO for the first time provides a preliminary guideline of its own kind. It is hoped that it could contribute to the transparent reporting of bibliometric reviews. The quality and utility of BIBILO remain to be investigated further.
