Abstract
Rising research and development costs, currently exceeding $3.5 billion per novel drug, reflect a five-decade decline in pharmaceutical R&D efficiency. While recent reports suggest a potential turnaround, this review offers a systems-level analysis to explore whether this marks a structural shift or transient reversal. We analyzed financial data from the 200 largest pharmaceutical firms, novel drug approvals, and more than 80000 clinical trials between 2012 and 2023. Our analysis revealed that despite recent stabilization, the pharmaceutical industry continues to face challenges, particularly due to elevated late-stage clinical attrition, suggesting that a sustained turnaround in R&D efficiency remains elusive.

Abstract
Galectins, which correspond to a group of proteins capable of recognizing and reversibly binding to β-galactoside carbohydrates, have been the subject of innovation and development of technological products. Galectins play biological roles, such as cell proliferation and apoptosis, and some studies showed differences in the concentrations of galectins dispersed in serum of patients with cancer. For this reason, different studies have evaluated the biotechnological potential of these proteins as biomarkers for the prognosis and/or diagnosis of physiological disorders. Thus, this review discusses recent technological advancements in targeting galectins for the treatment of cancer and using galectins for cancer prognosis and diagnosis. Data mining was performed using the search descriptors "Galectin 9* and cancer*" and the ESPACENET and Cortellis Drug Discovery Intelligence (CDDI) databases. PRISMA guidelines were followed as a basis for literature review which aimed to conduct a systematic study of galectin-9 patents related to cancer prognosis, diagnosis and treatment. Results showed the importance of galectin-9 protein patents in furthering biomedical advancements in the global fight against cancer.

Abstract
Probiotics are becoming increasingly popular due to their potential health benefits. With this rise in popularity and demand as indicated by ever-growing market prospects, it seems evident that innovation and valorization are on the rise as well. However, an increasing body of literature shows that innovation is stagnating, which may be detrimental to the exploitation of the benefits of probiotics, for example the development of alternative therapies to manage the increasing prevalence of metabolic and autoimmune disorders. To this end, this study investigated global clinical trials that have been executed since the year 2000 as a first indicator of the status of probiotic valorization. The cumulative number of clinical trials has indeed increased significantly from 0 at the start of the century up to 2,517 registered trials in 2023. However, in Asia, Europe, and North America, the continents with the highest numbers of clinical trials, stagnating or declining trends have been found. In these locations, most clinical trials were funded by non-industry sponsors and targeting probiotic supplements or undefined products. Considering the overall stagnation in clinical trials and viewing these trends in the context of developments in local markets and regulations, the global valorization of probiotics appears to slow down. This could impact the transition from academic research to the development of products that are beneficial and accessible for consumers, either to maintain a healthy lifestyle or to treat medical conditions.

Abstract
In recent years it has become evident that a healthy intestinal microbiome is beneficial for the overall health of an individual. A healthy microbiome is diverse, increasing stability and resilience and strengthening the immune system. In addition, healthy intestinal metabolisms have a beneficial effect on many physiological processes such as the brain function. Looking from the One Health perspective, which recognizes that health of humans is closely connected to the health of animals and environment, it is inherently beneficial to stimulate the health of animals for the well-being of humans. However, the intensive administration of antibiotics to livestock for prevention and cure of disease, and even stimulation of growth, disrupts a healthy microbiome. With the rapid increase of emerging zoonotic diseases, alternatives to the use of antimicrobial compounds are urgently necessary. This research analyses the development of alternatives for antibiotic use contributing to veterinary intestinal health through an in-depth patent analysis of inventions for fodder additives. In the period 1999–2020, 1269 unique patent families describing the use of probiotics, enzymes and prebiotics for swine, poultry and ruminants were identified. Innovation trends, geography, key applicants, and classification of patents were analysed. Asian industrial applicants applied for the majority of patents comprising the largest share of patents for probiotics and enzymes in combination with fodder for swine. Followed by North American and European industrial applications, applying for patents for probiotics in combination with fodder for poultry, swine, and ruminants. Overall, our results do not show a clear increase in innovations, suggesting that innovations in the use of probiotics and enzymes in animal feed appear to be stalling. While in the near future a combination of the use of antibiotics and alternatives is most likely to be implemented, the use of probiotics stands a good chance of replacing antibiotics in animal husbandry and limiting the adverse effects of antibiotic abuse. Alternatives for antibiotic use contributing to veterinary intestinal health are slowly coming to the market. Patent applications for probiotics, prebiotics, enzymes supporting a healthy veterinary intestine are stabilizing. China, as largest applicant for patents targeting the VIH,vcombines probiotics and enzymes with fodder for swine and poultry.

Abstract
The rise in prevalence of mental and neurological disorders is causing a high burden on society, however adequate interventions are not always available. The brain-gut-microbiota axis (BGMA) may provide a new angle for the development of clinical modalities. Due to the intricate bi-directional signaling between the brain and the gut, it may be helpful to look into interventions that target the gut, such as probiotics. Therefore, this review aimed to investigate the state of the art of probiotics and their potential as clinical modalities for BGMA-associated indications by gaining insight into patents and clinical trials that have been applied for and executed since 1999. A total of 565 patents and 390 clinical trials were found, focusing on probiotic applications for 83 indications. Since the start of the 21st century, the highest numbers of patents and clinical trials were related to primary neuropsychological, affective (depression, anxiety) and cognitive disorders, neurodegenerative and/or inflammatory brain disorders (Alzheimer's disease, Parkinson's disease, amongst others), and gastrointestinal disorders (irritable bowel syndrome). The locations where the most patents and clinical trials were registered included China, the United States, and Iran. From 1999 to ~2013 a slight growth could be seen in the numbers of patents and clinical trials, followed by an almost exponential growth from ~2013 onwards. Overall, the developments of the state of the art were in accordance with previous research, however it appeared that clinical trials showed a slightly slower growth compared to patents, which may have implications for the future implementation of probiotics as clinical modalities for BGMA-associated indications.

Abstract
The human microbiota have been implicated in the aetiology and remedy of a host of disorders. However, due to the pervasive uncertainty inherent in the field of microbiota-targeting interventions and associated issues with establishing rigorous safety and efficacy profiles, regulatory oversight is suboptimal. This can dissuade innovators from further exploring novel and much needed health interventions. Modification of regulatory protocols and practices requires focussed efforts and funding to build the evidence base around future regulatory needs. Such modification can be critically informed by identification of changes and trends in technology fields to facilitate identification of regulatory gaps. To this purpose, this study rigorously collected and analysed patent data from Espacenet - covering the years 2013-2018 - and created a patent landscape analysis of microbiome targeting interventions with a focus on medicinal products. Pertinent patenting activity has declined overall. While, in absolute terms, patents most frequently claimed inventions targeting disorders of the gut and alimentary tract, relative year-on-year interest increases have been substantial for cancer, and disorders of the (neuro-)muscular and respiratory systems - driven by the private sector. Academic stakeholders showed top interest in disorders of the metabolism, anti-infectives, and skeletal and dermatological diseases. Although medicinal preparation claims dominated our dataset, a third of patents claimed food preparations, while only 1% claimed application as a diagnostic. Finally, China is, by an inordinate margin, a market of particular interest for both domestic and foreign innovators, indicating that microbiome targeting intervention innovation for EU and US markets might be frustrated. This study is the first to empirically demonstrate that live biotherapeutic product innovation is decelerating and potentially frustrated, supporting the urgent need for improved regulatory standards. Our results indicate which disease areas deserve particular attention for research funding to facilitate proper regulatory appraisal in the near- to mid-term future.

Abstract
This review aims to provide insight into the potential of probiotics as a clinical modality targeted at infectious diseases by creating a comprehensive overview of the state of the art of research and development efforts as shown by patents and clinical trials of the past 20 years. Data were retrieved from patent and clinical trial databases to reflect the long- and short-term developments of probiotics research. The data were analyzed to extract information on the total number of patents and trials for each indication, application date and location, and applicant/sponsor type. A total of 80 infectious diseases were investigated, precipitating in 789 patents and 602 clinical trials for 67 indications studied as targets of probiotics. An increasing trend was seen for the number of patents and clinical trials that were applied for since 1999 with the highest number of patents and clinical trials targeted to digestive tract, respiratory, and urogenital indications. Overall, research demonstrated a substantial interest in probiotics targeting infectious diseases, which was in line with reported unmet needs and global probiotics sales estimates. However, the declining rate of translation from patents to clinical trials indicates that there are some barriers obstructing the research process.

Abstract
While the COVID-19 pandemic has led to increased focus on pathogenic microbes that cross the animal-human species barrier, calls to include non-pathogenic interactions in our perspective on public health are gaining traction in the academic community. Over generations, the diversity of the human gut microbiota is being challenged by external perturbations and reduced acquisition of symbiotic species throughout life. When such reduced diversity concerns not only the microbial species, but also the higher taxonomic levels and even the guild level, adequate compensation for possible losses may be lacking. Shifts from a high-abundance to a low-abundance state, known as a tipping point, may result in simultaneous shifts in covarying taxa and ultimately to a catastrophic collapse in which the ecosystem abruptly and possibly irreversibly shifts to an alternative state. Here, we propose that co-occurrence patterns within and between microbial communities across human, animal, soil, water, and other environmental domains should be studied in light of such critical transitions. Improved mechanistic understanding of factors that shape structure and function is needed to understand whether interventions can sustainably remodel disease-prone microbiota compositions to robust and resilient healthy microbiota. Prerequisites for a rational approach are a better understanding of the microbial interaction network, both within and inter-domain, as well as the identification of early warning signs for a catastrophic collapse, warranting a timely response for intervention. We should not forget that mutualism and pathogenicity are two sides of the same coin. Building upon the planetary health concept, we argue that microbiome research should include system level approaches to conserve ecosystem resilience. HIGHLIGHTS 1. Non-pathogenic interactions between ecosystems play a key role in maintaining health. 2. The human gut microbiome may be on the verge of a catastrophic collapse. 3. Research should identify keystone taxa and guilds that interconnect different domains. 4. We should not forget that mutualism and pathogenicity are two sides of the same coin.

Abstract
When taking a broader perspective on the societal impact of probiotics, engagement of end-users is important to discover unmet needs, define relevant health benefits and identify key considerations for successful implementation in daily practice. This study therefore takes a retrospective approach and analyses a database of user experiences to review the effects of four multispecies probiotic formulations. The user experiences were analysed in a dependent sample manner (without control group) and complement previous randomised controlled trials that have been performed with the formulations. The database consisted of 584 evaluable user experiences regarding the impact of probiotic supplementation on perceived quality of life (QoL), gastrointestinal (GIT) symptoms and reported stool consistency after two weeks of consumption. Two different scales were used (n=344 in a 5-point scale; n=240 in a 10-point scale), which are presented as separate analyses. In the combined population of the 5-point-scale questionnaire, a significant increase in perceived QoL and a significant reduction in perceived GIT symptoms was observed. Descriptive summaries also indicate that diarrhoea- and constipation-like stool patterns are reduced following supplementation. Moreover, half of participants indicated that probiotic supplementation had a positive effect on their unmet medical need, and 64% of users were likely to continue using the product. Similar results were observed in the 10-point scale questionnaire. Considering the clinical relevance of probiotic supplementation in specific target groups, subgroup analyses were performed on participants who consumed the products for diarrhoea, constipation, Inflammatory Bowel Disease, Irritable Bowel Syndrome, and antibiotic usage. Overall, findings support the potential of probiotics to advance perceived human health and support the daily wellbeing of users. This systematic analysis of user experiences thereby contributes to the external validity of studies evaluating clinical effects of probiotics and increases knowledge on their societal impact.

Abstract
In support of the J curve that describes the association between wine consumption and all-cause mortality, researchers and the lay press often advocate the health benefits of (poly)phenol consumption via red wine intake and cite the vast amount of in vitro literature that would corroborate the hypothesis. Other researchers dismiss such evidence and call for total abstention. In this review, we take a skeptical, Pythagorean stance and we critically try to move the debate forward by pointing the readers to the many pitfalls of red wine (poly)phenol research, which we arbitrarily treat as if they were pharmacological agents. We conclude that, after 30 years of dedicated research and despite the considerable expenditure, we still lack solid, "pharmacological", human evidence to confirm wine (poly)phenols' biological actions. Future research will eventually clarify their activities and will back the current recommendations of responsibly drinking moderate amounts of wine with meals.
