Abstract
Biliary tract cancer (BTC) is an uncommon and aggressive neoplasm, with most patients presenting in an advanced stage. Systemic chemotherapy is the limited treatment available but is unsatisfactory, while targeted therapy is still awaiting validation from clinical trials. Given the potential effect of immune checkpoint inhibitors (ICIs) in the treatment of BTC, this review aims to summarize the evidence-based benefits and predictive biomarkers for using inhibitors of cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) ligand, or programmed cell death protein-1 and its ligand (PD-1 and PD-L1) as monotherapy or combined with other anti-tumor therapies, while also pointing out certain pitfalls with the use of ICIs which need to be addressed.

Abstract
Definitive diagnosis and selection of effective treatment for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) are frustrations encountered frequently by urology care providers in their practice. Knowledge of etiology and pathophysiology is not sufficient and therapeutic guidelines have not yielded acceptable outcomes and prognoses for both patients and care providers. The authors present updated perspectives on CP/CPPS, including definition, diagnosis, treatment, and prognosis, based on literature review and clinical experience. A key point is to shift the diagnostic and therapeutic focus from a single entity of disease toward associated symptoms of CP/CPPS. An individualized multimodal treatment approach to cope with the course of the disorder is proposed. Communications and personal/family/community supports are emphasized as an important component in the therapeutic regime and rehabilitation of patients with CP/CPPS. The purpose is to improve comprehension on CP/CPPS and to help care providers and patients to achieve the goal of medical intervention-relieving associated symptoms of CP/CPPS and improving the quality of life.

Abstract
Oxaliplatin is an essential drug in the chemotherapy of colorectal, gastric, and pancreatic cancers, but it frequently causes peripheral neuropathy as a dose-limiting factor. So far, animal models of oxaliplatin-induced peripheral neuropathy have been established. The mechanisms of development of neuropathy induced by oxaliplatin have been elucidated, and many drugs and agents have been proven to have neuroprotective effects in basic studies. In addition, some of these drugs have been validated in clinical studies for their inhibitory effects on neuropathy. In this review, we summarize the basic and clinical evidence for the therapeutic effects of oxaliplatin. In basic research, there are many reports of neuropathy inhibitors that target oxidative stress, inflammatory response, sodium channel, transient receptor potential (TRP) channel, glutamate nervous system, and monoamine nervous system. Alternatively, very few drugs have clearly demonstrated the efficacy for oxaliplatin-induced peripheral neuropathy in clinical trials. It is important to activate translational research in order to translate basic research into clinical research.

Abstract
BACKGROUND Traditional Chinese medicine (TCM) is widely integrated into cancer care in China. An overview in 2011 identified 2384 randomized and non-randomized controlled trials (RCTs, non-RCTs) on TCM for cancer published in the Chinese literature. This article summarizes updated evidence of RCTs on TCM for cancer care. METHODS We searched 4 main Chinese databases: China National Knowledge Infrastructure, Chinese Scientific Journal Database, SinoMed, and Wanfang. RCTs on TCM used in cancer care were analyzed in this bibliometric study. RESULTS Of 5834 RCTs (477 157 cancer patients), only 62 RCTs were indexed in MEDLINE. The top 3 cancers treated were lung, stomach, and breast cancer. About 4752 RCTs (81.45%) tested TCM combined with conventional treatment, and 1082 RCTs (18.55%) used TCM alone for treating symptoms and side-effects. Herbal medicine was the most frequently used TCM modality (5087 RCTs; 87.20%). The most frequently reported outcome was symptom improvement (3712 RCTs; 63.63%) followed by quality of life (2725 RCTs; 46.71%), and biomarkers (2384 RCTs; 40.86%). The majority of RCTs (4051; 69.44%) concluded there were beneficial effects using either TCM alone or TCM plus conventional treatment compared with conventional treatment. CONCLUSION Substantial randomized trials demonstrated different types/stages of cancer were treated by various TCM modalities, alone or in combination with conventional medicine. Further evaluation on the effects and safety of TCM modalities focusing on outcomes such as quality of life is required.

Abstract
OBJECTIVE Matrix metalloproteinases (MMPs) substantially contribute to the development of chronicity in wounds. Thus, MMP-inhibiting dressings may support healing. A systematic review was performed to determine the existing evidence base for the treatment of hard-to-heal wounds with these dressings. METHODS A systematic literature search in databases and clinical trial registers was conducted to identify randomised controlled trials (RCTs) investigating the efficacy of MMP-inhibiting dressings. Studies were analysed regarding their quality and clinical evidence. RESULTS Of 721 hits, 16 relevant studies were assessed. There were 13 studies performed with collagen and three with technology lipido-colloid nano oligosaccharide factor (TLC-NOSF) dressings. Indications included diabetic foot ulcers, venous leg ulcers, pressure ulcers or wounds of mixed origin. Patient-relevant endpoints comprised wound size reduction, complete wound closure, healing time and rate. Considerable differences in the quality and subsequent clinical evidence exist between the studies identified. Substantial evidence for significant improvement in healing was identified only for some dressings. CONCLUSION Evidence for the superiority of some MMP-inhibiting wound dressings exists regarding wound closure, wound size reduction, healing time and healing rate. More research is required to substantiate the existing evidence for different types of hard-to-heal wounds and to generate evidence for some of the different types of MMP-inhibiting wound dressings.

Abstract
This article comments on the new approach to the clinical evaluation of medical devices in the European Union (EU), which adds consideration of intended clinical benefits to the traditional focus on safety and performance. The article also discusses types of clinical benefits that may be claimed and how evidence for them may be generated. In the EU, determining the benefit-risk profile is an existing core requirement of the clinical evaluation performed according to MEDDEV 2.7/1 Rev 4 guidelines, but under the new Medical Device Regulation (MDR), "intended" clinical benefits must be determined first.The MDR sets high standards for ensuring reliable data are generated from clinical investigations. It stipulates that the endpoints of clinical investigations should include clinical benefits. However, many clinical-use questions arise only after a device is made widely available to patients. For all medical devices, particularly for on-the-market devices never subjected to randomized controlled trials and for new devices developed when these trials were inappropriate/impossible, the postmarket phase of the device is a valuable source of clinical-benefit data. Postmarket clinical follow-up can corroborate and refine predictions of clinical benefits over time. Indirect clinical effects, which may affect treatment adherence and influence patients' well-being, may surface in the postmarket phase.Real-world clinical data will improve the manufacturer's understanding of their device's clinical benefits, potentially changing claims of intended clinical benefits in subsequent clinical evaluations. A paradigm change in clinical evaluation of medical devices in the EU will ensue when manufacturers ensure that their devices deliver real-world clinical benefits.

Abstract
Lactic acid bacteria (LAB) are known for their biotechnological potential. Moreover, LAB are distinguished by amazing criteria: Adjusting the intestinal environment, inhibiting pathogenic microbes in the gastrointestinal tract, ability to reduce pathogen adhesion activity, improving the balance of the microbiota inside the intestine, capabilities of regulating intestinal mucosal immunity, and maintaining intestinal barrier function. The escalating number of research and studies about beneficial microorganisms and their impact on promoting health has attracted a big interest in the last decades. Since antiquity, various based fermented products of different kinds have been utilized as potential probiotic products. Nevertheless, the current upsurge in consumers' interest in bioalternatives has opened new horizons for the probiotic field in terms of research and development. The present review aims at shedding light on the world of probiotics, a continuous story of astonishing success in various fields, in particular, the biomedical sector and pharmaceutical industry, as well as to display the importance of probiotics and their therapeutic potential in purpose to compete for sturdy pathogens and to struggle against diseases and acute infections. Shadows and future trends of probiotics use are also discussed.

Abstract
Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. To date, there is an increasing number of commercially available products containing probiotics on the market. Probiotics have been recommended by health care professionals for reasons ranging from their long-term immunomodulatory effects to proven benefits in the management of different health conditions. For probiotic products, there are several important aspects that determine the success rate of the development from bench to market. The aim of this review is to explore how the current knowledge on microbe–microbe and host–microbe interactions can be used to develop high-quality, evidence-based probiotic formulations, specifically probiotic dietary supplements, with a focus on the selection of safe strains with relevant functional properties. In addition, we will highlight aspects of the probiotic manufacturing process that need to be considered during the product development and the subsequent manufacturing process to guarantee consistent efficacy of a probiotic product. For each high-quality probiotic formulation, it is important to screen multiple strains, and select only those strains that show relevant functional properties and that can be considered safe for human consumption. In addition, it is imperative that attention is paid to the product development and manufacturing process, and that safety and quality properties are monitored. Importantly, the beneficial effects of probiotics should be evaluated in product efficacy studies and post-marketing surveys in order to demonstrate their clinical efficacy. All these aspects need to be evaluated and validated during the development of a successful high-quality and ready-to-market probiotic.

Abstract
Introduction: The ILUVIEN® (fluocinolone acetonide) Clinical Evidence in
Portugal (ICE-PT) study is a retrospective, multicenter, observational study
evaluating the effectiveness and safety of the FAc implant in patients with
diabetic macular edema. Methods: Patients included in this study had received the 0.2 µg/day fluocinolone
acetonide implant for the treatment of diabetic macular edema and had
measurements of visual acuity and retinal thickness assessed by optical
coherence tomography for at least 12 months pre- and post-fluocinolone
acetonide implant administration, with ⩾2 follow-up visits. Outcomes
measured included visual acuity, central foveal thickness, and intraocular
pressure. Results: There was a significant increase in mean visual acuity compared with baseline
at 3, 6, 9, and 12 months post-fluocinolone acetonide in both the overall
study population and the pseudophakic subgroup (p < 0.05
at all time points in both groups). A significant reduction in mean central
foveal thickness compared with baseline was seen in the overall study
population at 3, 6, 9, and 12 months post-fluocinolone acetonide
(p < 0.05 at all time points). At 12-month
post-fluocinolone acetonide, a small but significant intraocular pressure
increase of 1.0 mmHg was seen in the overall study population. Conclusion: The results of this analysis show that switching from the current standard of
care to the fluocinolone acetonide implant leads to beneficial effects in
terms of vision and retinal structure in patients with diabetic macular
edema and that patients benefited from FAc implant administration,
regardless of lens status.

Abstract
Purpose The 0.19 mg fluocinolone acetonide (FAc) intravitreal implant is approved in the United Arab Emirates (UAE) for treating diabetic macular edema (DME) in patients previously treated with a course of corticosteroids and that did not have a clinically significant rise in intraocular pressure (IOP). This ongoing study is assessing its effectiveness and safety in pseudophakic patients with DME in clinical practice from a single center in the UAE. Methods A retrospective, ongoing 6-month audit study (NCT03590587), in which 22 eyes from 22 patients were treated with a single FAc intravitreal implant after treatment with a prior course of corticosteroids. Outcomes assessed included mean changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and IOP. Six-month follow-up data are presented. Results After FAc implantation, mean BCVA improved rapidly, increasing by 25.4 ± 3.0 letters (mean±SEM) from baseline to Month 6 (p<0.0001). At 6 months, BCVA had improved by 15 letters or more in 91% of eyes (n=20/22). Mean CMT decreased by 267.0 ± 20.1 µm from baseline to Month 6 (p<0.0001). Over 85% of eyes (n=19/22) had a CMT less than 300 µm at 6 months. Mean IOP increased by 2.9 ± 0.7 mmHg from baseline to Month 6 (p<0.001). All eyes except 2 had an IOP of 21 mmHg or lower. At Month 6, five eyes (23%) needed IOP-lowering therapy. Conclusion Injection of the FAc intravitreal implant rapidly and significantly improved BCVA and CMT within 6 months. These rapid and significant improvements exceed those reported in other real-world studies. Safety signals were consistent with corticosteroid class effects. The FAc implant may be a useful treatment option for patients in the UAE, particularly those with sight threatening DME requiring rapid functional improvements.

Abstract
INTRODUCTION The management of a child with juvenile idiopathic arthritis (JIA) requires a combination of pharmacological, physical, and psychosocial therapies in order to induce disease remission, by controlling articular and systemic inflammation. This review aims to provide a comprehensive discussion on the biological therapies currently in use in the treatment of JIA referring to existing recommendations and clinical evidence. We also discuss on the emerging biological drugs actually under consideration. AREAS COVERED Recent findings on immunological mechanisms involved in the pathogenesis of the disease allowed us to identify several specific targets for biologic therapies. A systematic literature review was conducted between January 1997 and January 2020 on PubMed including national and international guidelines and recommendations, trials and case-control studies. EXPERT OPINION There is now a plethora of therapies that are directed against variable targets, and the physician has to choose the most appropriate available medication in order to achieve early and sustained remission with as few side effects as possible. Research is advancing very fast in order to be more and more specific in suppressing inflammatory pathways without harming natural defenses. Finally, pharmacoeconomic considerations will also be very important to deal with, considering the high cost of most of these molecules.

Abstract
OBJECTIVE Since December 2019, an outbreak of corona virus disease 2019 (COVID-19) occurred in Wuhan, and rapidly spread to almost all parts of China. This was followed by prevention programs recommending Chinese medicine (CM) for the prevention. In order to provide evidence for CM recommendations, we reviewed ancient classics and human studies. METHODS Historical records on prevention and treatment of infections in CM classics, clinical evidence of CM on the prevention of severe acute respiratory syndrome (SARS) and H1N1 influenza, and CM prevention programs issued by health authorities in China since the COVID-19 outbreak were retrieved from different databases and websites till 12 February, 2020. Research evidence included data from clinical trials, cohort or other population studies using CM for preventing contagious respiratory virus diseases. RESULTS The use of CM to prevent epidemics of infectious diseases was traced back to ancient Chinese practice cited in Huangdi's Internal Classic (Huang Di Nei Jing) where preventive effects were recorded. There were 3 studies using CM for prevention of SARS and 4 studies for H1N1 influenza. None of the participants who took CM contracted SARS in the 3 studies. The infection rate of H1N1 influenza in the CM group was significantly lower than the non-CM group (relative risk 0.36, 95% confidence interval 0.24-0.52; n=4). For prevention of COVID-19, 23 provinces in China issued CM programs. The main principles of CM use were to tonify qi to protect from external pathogens, disperse wind and discharge heat, and resolve dampness. The most frequently used herbs included Radix astragali (Huangqi), Radix glycyrrhizae (Gancao), Radix saposhnikoviae (Fangfeng), Rhizoma Atractylodis Macrocephalae (Baizhu), Lonicerae Japonicae Flos (Jinyinhua), and Fructus forsythia (Lianqiao). CONCLUSIONS Based on historical records and human evidence of SARS and H1N1 influenza prevention, Chinese herbal formula could be an alternative approach for prevention of COVID-19 in high-risk population. Prospective, rigorous population studies are warranted to confirm the potential preventive effect of CM.

Abstract
The research aims to propose the approaches to the clinical trial of acupuncture and moxibustion and provide the methodological guide for the research in this field in terms of the inadequate systematic collection, lack of the specific characteristics of acupuncture-moxibustion treatment and insufficient persuasion in clinical evidences of acupuncture-moxibustion research. Through a systematic review of the registration of acupuncture-moxibustion clinical trials at home and abroad, the distribution of diseases with the recommendation of acupuncture and moxibustion in Cochrane Library database, combined with the evidence grade of the evidence-based medicine and the individual characteristics of clinical practice with acupuncture and moxibustion, some research ideas and framework are proposed for the clinical trial of acupuncture and moxibustion. To take the curative effect as the forerumer, the dominant disease and therapeutic methods of acupuncture and moxibustion should be initially generalized by the case experiences and clinical observation at the first. In view of the potential function of acupuncture and moxibustion in treatment, the rigorous and standardized clinical trial should be carried out to verify their therapeutic effect. Finally, the experimental research is adopted to explore the mechanism of acupuncture and moxibustion. Through the combination of quantitative and qualitative methods, all of the evidences are integrated to form an integrative evidence chain. It is anticipated that the construction of the integrative evidence chain in clinical trial of acupuncture and moxibustion may enhance the promotion of clinical practice with acupuncture and moxibustion and increase the influence of acupuncture-moxibusiton discipline.

Abstract
OBJECTIVE Scientific papers and books on digital dentistry are in vogue. In most cases, these publications focus clearly on the - undoubted - potentials and possibilities offered by digitalization. The fact that digital dentistry necessarily entails risks and ethical challenges, by contrast, is rarely discussed. This paper aims to complement the discourse on digitalization in dentistry by analyzing precisely these challenges. METHOD AND MATERIALS The study is based on an analysis of international publications and specialist writings on digitalization and its applications in the fields of dentistry and medicine, as well as on the analysis of specific contributions from the disciplines of medical ethics and medical law, and from the public media. RESULTS The paper identifies and discusses eight core challenges: (1) big data ("digital double" and falsification in dentistry), (2) the dental practitioner-patient relationship, (3) digital literacy, (4) the assumption of responsibility in complex systems, (5) accompanying changes in the dental professions, (6) cost trap and risks of overtreatment in dentistry, (7) consumption spiral and ecologic footprint, and (8) clinical evidence in dental treatments. In addition, a catalog of criteria for assessing the effects of digitalization in dentistry is developed. CONCLUSION It is crucial to closely monitor both the potentials and the challenges posed by digitalization in dentistry. Ultimately, it is only those problems that are identified as such that can be resolved and only those technologies that are accepted by dentists, patients, and society that will prevail in the long term.

Abstract
Cannabis sativa L. is a plant long used for its textile fibers, seed oil, and oleoresin with medicinal and psychoactive properties. It is the main source of phytocannabinoids, with over 100 compounds detected so far. In recent years, a lot of attention has been given to the main phytochemicals present in Cannabis sativa L., namely, cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC). Compared to THC, CBD has non-psychoactive effects, an advantage for clinical applications of anti-tumor benefits. The review is designed to provide an update regarding the multi-target effects of CBD in different types of cancer. The main focus is on the latest in vitro and in vivo studies that present data regarding the anti-proliferative, pro-apoptotic, cytotoxic, anti-invasive, anti-antiangiogenic, anti-inflammatory, and immunomodulatory properties of CBD together with their mechanisms of action. The latest clinical evidence of the anticancer effects of CBD is also outlined. Moreover, the main aspects of the pharmacological and toxicological profiles are given.

Abstract
Background: Epidemiological data reveal that treatment with lithium, a mood stabilizer, is associated with decreased incidence and mortality of certain cancer types, such as melanoma. Therefore, repositioning of lithium as an anticancer agent has emerged as a promising strategy in oncology. Since lithium affects the physiology of several endocrine tissues, the goal of this study was to analyze the role of lithium in the pathogenesis and treatment of tumors of the endocrine system. Methods: The databases of PubMed, EMBASE, MEDLINE, were searched from January 1970 through February 2019 for articles including the keywords "lithium and"-"thyroid cancer," "thyroid nodule," "parathyroid adenoma," "parathyroid carcinoma," "pituitary adenoma," "pituitary neuroendocrine tumor," "neuroendocrine tumor," "carcinoid," "adrenal adenoma," "adrenal carcinoma," "pheochromocytoma/paraganglioma." Preclinical in vitro and in vivo studies as well as case series, retrospective cohort studies and prospective trials were selected for the analysis. Results: Treatment with lithium has been associated with a higher prevalence of thyroid enlargement, hypothyroidism and increased calcium levels due to parathyroid adenoma or hyperplasia, as one of the mechanisms of its action is to stimulate proliferation of normal follicular thyroid and parathyroid cells via activation of the Wnt signaling pathway. Supratherapeutic concentrations of lithium decrease the activity of glycogen synthase kinase-3β (GSK-3β), leading to cell cycle arrest in several in vitro cancer models including medullary thyroid cancer (TC), pheochromocytoma/paraganglioma and carcinoid. Growth inhibitory effects of lithium in vivo have been documented in medullary TC xenograft mouse models. Clinically, lithium has been used as an adjuvant agent to therapy with radioactive iodine (RAI), as it increases the residence time of RAI in TC. Conclusion: Patients chronically treated with lithium need to be screened for hypothyroidism, goiter, and hyperparathyroidism, as the prevalence of these endocrine abnormalities is higher in lithium-treated patients than in the general population. The growth inhibitory effects of lithium in medullary TC, pheochromocytoma/paraganglioma and carcinoid were achieved with supratherapeutic concentrations of lithium thus limiting its translational perspective. Currently available clinical data on the efficacy of lithium in the therapy of endocrine tumors in human is limited and associated with conflicting results.

Abstract
This article comments on the new approach to the clinical evaluation of medical devices in the European Union (EU), which adds consideration of intended clinical benefits to the traditional focus on safety and performance. The article also discusses types of clinical benefits that may be claimed and how evidence for them may be generated. In the EU, determining the benefit-risk profile is an existing core requirement of the clinical evaluation performed according to MEDDEV 2.7/1 Rev 4 guidelines, but under the new Medical Device Regulation (MDR), "intended" clinical benefits must be determined first. The MDR sets high standards for ensuring reliable data are generated from clinical investigations. It stipulates that the endpoints of clinical investigations should include clinical benefits. However, many clinical-use questions arise only after a device is made widely available to patients. For all medical devices, particularly for on-the-market devices never subjected to randomized controlled trials and for new devices developed when these trials were inappropriate/impossible, the postmarket phase of the device is a valuable source of clinical-benefit data. Postmarket clinical follow-up can corroborate and refine predictions of clinical benefits over time. Indirect clinical effects, which may affect treatment adherence and influence patients' well-being, may surface in the postmarket phase. Real-world clinical data will improve the manufacturer's understanding of their device's clinical benefits, potentially changing claims of intended clinical benefits in subsequent clinical evaluations. A paradigm change in clinical evaluation of medical devices in the EU will ensue when manufacturers ensure that their devices deliver real-world clinical benefits.

Abstract
Coronary heart disease (CHD) remains a major cause of mortality with a huge economic burden on healthcare worldwide. Here, we conducted a systematic review to investigate the efficacy and safety of Chinese herbal medicine (CHM) for CHD based on high-quality randomized controlled trials (RCTs) and summarized its possible mechanisms according to animal-based researches. 27 eligible studies were identified in eight database searches from inception to June 2018. The methodological quality was assessed using seven-item checklist recommended by Cochrane Collaboration. All the data were analyzed using Rev-Man 5.3 software. As a result, the score of study quality ranged from 4 to 7 points. Meta-analyses showed CHM can significantly reduce the incidence of myocardial infarction and percutaneous coronary intervention, and cardiovascular mortality (P < 0.05), and increase systolic function of heart, the ST-segment depression, and clinical efficacy (P < 0.05). Adverse events were reported in 11 studies, and CHMs were well tolerated in patients with CHD. In addition, CHM exerted cardioprotection for CHD, possibly altering multiple signal pathways through anti-inflammatory, anti-oxidation, anti-apoptosis, improving the circulation, and regulating energy metabolism. In conclusion, the evidence available from present study revealed that CHMs are beneficial for CHD and are generally safe.

Abstract
Juvenile Idiopathic Arthritis (JIA) is one of the most common chronic diseases in children. Recently, the management of JIA has substantially changed, thanks to the availability of new treatment options, represented by biological drugs or biologics. These drugs modulate the specific mechanisms of the immune systems, such as TNF-α, IL-1 and IL-6 signaling, or lymphocyte activation and/or functioning. In this review, we provide a comprehensive discussion on the current recommendations and clinical evidence regarding the use of the available biologics in the treatment of JIA; moreover, the main pharmacokinetic and pharmacodynamic aspects of any specific biologic drug have been summarized.

Abstract
Platelet-rich plasma (PRP) is defined as a volume of plasma with a platelet
concentration higher than the average in peripheral blood. Many basic,
preclinical and even clinical case studies and trials report PRP’s ability to
improve musculoskeletal conditions including osteoarthritis, but paradoxically,
just as many conclude it has no effect. The purpose of this narrative review is
to discuss the available relevant evidence that supports the clinical use of PRP
in osteoarthritis, highlighting those variables we perceive as critical. Here,
recent systematic reviews and meta-analyses were used to identify the latest
randomized controlled trials (RCTs) testing a PRP product as an intra-articular
treatment for knee osteoarthritis, compared with an intra-articular control
(mostly hyaluronic acid). Conclusions in the identified RCTs are examined and
compared. In total, five recent meta-analyses and systematic reviews were found
meeting the above criteria. A total of 19 individual trials were identified in
the five reviews but only 9 were level of evidence I RCTs, and many had moderate
or high risks of bias. At present, results from these RCTs seem to favor PRP use
over other intra-articular treatments to improve pain scales in the short and
medium term (6–12 months), but the overall level of evidence is low. As a
result, clinical effectiveness of PRP for knee osteoarthritis treatment is still
under debate. This is, prominently, the result of a lack of standardization of
PRP products, scarceness of high quality RCTs not showing high risks of bias,
and poor patient stratification for inclusion in the RCTs.

Abstract
BACKGROUND Chemically modified allergen extracts, known as allergoids, are commonly used for treating allergic patients. In general terms, the concept of allergoids implies allergen extracts with a reduction of their allergenicity maintaining their immunogenicity. Different methods to obtain allergoids have been developed in the past years, opening attractive lines of research. OBJECTIVE To review the different approaches to allergoid development as well as their characterization, mechanism of action and efficacy and safety issues. METHODS A revision and analysis of the different types of allergoids has been performed, with special attention to patents submitted and granted in the last years. Additionally, updated information about the mechanism of action and clinical evidence and safety of allergoids has been discussed. RESULTS Principally, allergoids are obtained by the polymerization of native allergen extracts with aldehydes, including formaldehyde or glutaraldehyde. However, recent patents and publications about different chemical modifications have been presented, as well as about the use of new adjuvants with allergoids. Regarding the characterization, allergoids require more sophisticated analytical methods than native extracts, as a consequence of their properties and characteristics. CONCLUSION In the last years, the partial understanding of the mechanism of action and the generation of clinical evidence of different types of allergoids, linked to their excellent safety profile and their convenience for a quick build up phase, have made of allergoids an excellent product for allergy treatment.

Abstract
It is well known that chronic pain is prevalent, complex to manage, and associated with high costs, in health care and society in general. Thanks to advances in new forms of cognitive behavioral therapy (known as third-wave CBT), currently clinicians and researchers have an empirically validated psychological treatment with increasing research support for the treatment of chronic pain. This treatment is called acceptance and commitment therapy (ACT). The main aim of this paper is to provide a narrative review that summarizes and integrates the current state of knowledge of ACT in the management of chronic pain as well as discuss current challenges and opportunities for progress. Based on the psychological flexibility model, ACT extends previous forms of CBT and integrates many CBT-related variables into six core therapeutic processes. ACT is a process-based therapy that fosters openness, awareness, and engagement through a wide range of methods, including exposure-based and experiential methods, metaphors, and values clarification. To our knowledge, there are three published systematic reviews and meta-analyses that support the effectiveness of ACT for chronic pain and many studies focused on specific processes derived from the psychological flexibility model. There is also promising support for the cost-effectiveness of ACT; however, the current evidence is still insufficient to establish firm conclusions about cost-effectiveness and the most efficient means of delivery. Additional well-designed economic evaluations are needed. Other research aims include delineating the neurobiological underpinnings of ACT, refining available outcome and process measures or develop new ones for ACT trials, and meeting the challenge of wide dissemination and implementation in real-world clinical practice.

Abstract
This systematic review aimed to determine whether there is consensus for antibiotic prescription in healthy patients undergoing implant placement. A search of PubMed, Embase and Medline databases was conducted in January 2016 to find published journal articles on the use of antibiotics in implant placement, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The inclusion criteria were prospective human clinical trials investigating antibiotic usage during implant placement. Fifteen studies were deemed suitable. In 13 studies, no statistical difference was found between antibiotic use and the incidence of prosthetic failure, implant failure and early postoperative infections. These were rated as having low to high risk bias. Contrary results were reported in two studies, both of which were rated as having a high potential for bias. In conclusion, antibiotic use in healthy patients for the prophylaxis of surgical infection associated with dental implant placement does not appear to improve clinical outcomes. Practitioners should apply principles of antimicrobial stewardship and not use antibiotics as a routine measure in healthy patients.

Abstract
Herpes zoster (HZ) is an acute viral illness characterized by a vesicular rash with unilateral distribution, which can also result in severe complications such as post-herpetic neuralgia (PHN), ophthalmic zoster, stroke or other neurological complications. The estimate incidence in Europe ranges between 2.0 and 4.6 cases per 1,000 person-years, with a sharp increase in >50 year-old subjects. Currently, treatment options for HZ are only partially effective in limiting the acute phase, while the management of complications is complex and often unsatisfactory. The total burden of the disease and the high costs related to its diagnostic and therapeutic management led researchers to develop a new preventive approach through a live attenuated virus vaccine. The currently available vaccine, with a high antigen content, is safe, well tolerated and reduces the incidence of HZ, PHN and the burden of illness. Several countries have introduced this vaccination, albeit with different recommendations and methods of financing. Taking into account the barriers to this immunization registered in some areas (difficulty of vaccine distribution, lack of physician recommendations, the cost of vaccine for patients, etc.), this group of Italian experts advocate that a common strategy able to guarantee a good compliance with this vaccination should be implemented. The same group addresses some practical questions concerning the use of zoster vaccine.

Abstract
PURPOSE The pathogenesis of chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) is complex and remains poorly understood. Evidence regarding the use of drug therapies in CFS/ME is currently limited and conflicting. The aim of this systematic review was to examine the existing evidence on the efficacy of drug therapies and determine whether any can be recommended for patients with CFS/ME. METHODS MEDLINE, EMBASE, and PubMed databases were searched from the start of their records to March 2016 to identify relevant studies. Randomized controlled trials focusing solely on drug therapy to alleviate and/or eliminate chronic fatigue symptoms were included in the review. Any trials that considered graded exercise therapy, cognitive behavior therapy, adaptive pacing, or any other nonpharmaceutical treatment plans were excluded. The inclusion criteria were examined to ensure that study participants met specific CFS/ME diagnostic criteria. Study size, intervention, and end point outcome domains were summarized. FINDINGS A total of 1039 studies were identified with the search terms; 26 studies met all the criteria and were considered suitable for review. Three different diagnostic criteria were identified: the Holmes criteria, International Consensus Criteria, and the Fukuda criteria. Primary outcomes were identified as fatigue, pain, mood, neurocognitive dysfunction and sleep quality, symptom severity, functional status, and well-being or overall health status. Twenty pharmaceutical classes were trialed. Ten medications were shown to be slightly to moderately effective in their respective study groups (P < 0.05). IMPLICATIONS These findings indicate that no universal pharmaceutical treatment can be recommended. The unknown etiology of CFS/ME, and complications arising from its heterogeneous nature, contributes to the lack of clear evidence for pharmaceutical interventions. However, patients report using a large number and variety of medications. This finding highlights the need for trials with clearly defined CFS/ME cohorts. Trials based on more specific criteria such as the International Consensus Criteria are recommended to identify specific subgroups of patients in whom treatments may be beneficial.

Abstract
Erectile dysfunction (ED) is a very common disorder with a deep impact on quality of life on both patients and partners. Several options are available for treating ED: oral pharmacotherapy with phosphodiesterase 5 (PDE5) inhibitors currently represents the first-line option for many patients with ED. Alprostadil, a prostaglandin, has been marketed for many years as a urethral stick and an intracavernous injection for the treatment of ED. It is now available in the form of a cream (Vitaros/Virirec), a noninvasive treatment which combines an active drug (alprostadil, a synthetic prostaglandin E1) with a skin enhancer improving its local absorption directly at the site of action. Alprostadil has a favourable pharmacodynamic profile and is poorly absorbed in systemic circulation, which makes it suitable in a lot of circumstances and results in a reduced risk of adverse effects (AEs). Systemic AEs are reported in only 3% of the treated population. Clinical efficacy has been demonstrated in both phase II and III trials, showing a global efficacy up to 83% with the 300 μg dose in patients with severe ED, significantly better than placebo. Its fast onset of action and lack of interactions with other drugs makes alprostadil cream a possible first-line therapeutic option for some patients with ED: individuals who are reluctant to take systemic treatments or have AEs, patients who do not respond, cannot tolerate, or do not accept PDE5 inhibitor therapy, and patients treated with nitrates. Therefore, this new treatment for ED can be offered to patients and could help address the needs unmet by other treatments.

Abstract
Topical 5% lidocaine medicated plasters represent a well-established first-line option for the treatment of peripheral localized neuropathic pain (LNP). This review provides an updated overview of the clinical evidence (randomized, controlled, and open-label clinical studies, real-life daily clinical practice, and case series). The 5% lidocaine medicated plaster effectively provides pain relief in postherpetic neuralgia, and data from a large open-label controlled study indicate that the 5% lidocaine medicated plaster is as effective as systemic pregabalin in postherpetic neuralgia and painful diabetic polyneuropathy but with an improved tolerability profile. Additionally, improved analgesia and fewer side effects were experienced by patients treated synchronously with the 5% lidocaine medicated plaster, further demonstrating the value of multimodal analgesia in LNP. The 5% lidocaine medicated plaster provides continued benefit after long-term (≤7 years) use and is also effective in various other LNP conditions. Minor application-site reactions are the most common adverse events associated with the 5% lidocaine medicated plaster; there is minimal risk of systemic adverse events and drug–drug interactions. Although further well-controlled studies are warranted, the 5% lidocaine medicated plaster is efficacious and safe in LNP and may have particular clinical benefit in elderly and/or medically compromised patients because of the low incidence of adverse events.

Abstract
RATIONALE, AIMS AND OBJECTIVE A delayed availability of clinical evidence in rapidly emerging therapies is considered a major problem. In this study, we examined whether evidence from clinical studies has influenced the therapy of a major disease in industrial countries, peripheral arterial disease (PAD), using novel femoropopliteal stent-angioplasty. METHOD This analysis of retrospective time series data uses multivariate linear regression to investigate associations between published clinical evidence on femoropopliteal stent-angioplasty from Q3/2004 to Q4/2010 and the demand for femoropopliteal stents in Germany, France, Italy and the UK between Q1/2005 and Q4/2010, controlling for the prevalence of PAD risk factors, cardiovascular drug demand, reimbursement of health care providers for stent implantation, stent selling prices of manufacturers and economic indicators. RESULTS We did not observe any association of published clinical evidence with femoropopliteal stent demand in Germany, France, Italy and the UK, while we observed such associations for varying control variables at different time lags respectively. CONCLUSION We observed no association between published clinical evidence of femoropopliteal stent-angioplasty and its use in any of the four countries. The country-specific context and practice-related variables at a centre and individual doctor level may have limited the role of published clinical evidence in emerging femoropopliteal stent-angioplasty. More research is needed at this context, centre and individual level.

Abstract
The preferential metastasis of cancer cells to bone disrupts the process of bone remodeling and results in serious complications. Although bone imaging techniques are well established for bone metastasis diagnosis, they still have limits. Recently, small noncoding RNA molecules, called miRNAs, have become the subject of interest in many molecular pathways in relation to bone metastasis. Furthermore, studies have demonstrated the ability to distinguish normal from cancerous cells and metastatic bone tumor origin based on miRNA profiles. Here, we summarize the data on mechanisms of osteolytic and osteoblastic bone metastases supporting the involvement of miRNA changes in the bone metastatic evolution. We also focus on the available evidence regarding current clinical studies of miRNA expression in the detection of bone metastases.

Abstract
Manufacturers launching next-generation or innovative medical devices in Europe face a very heterogeneous reimbursement landscape, with each country having its own pathways, timing, requirements and success factors. We selected 2 markets for a deeper look into the reimbursement landscape: France, representing a country with central decision making with defined processes, and Italy, which delegates reimbursement decisions to the regional level, resulting in a less transparent approach to reimbursement. Based on our experience in working on various new product launches and analyzing recent reimbursement decisions, we found that payers in both countries do not reward improved next-generation products with incremental reimbursement. Looking at innovations, we observe that manufacturers face a challenging and lengthy process to obtain reimbursement. In addition, requirements and key success factors differ by country: In France, comparative clinical evidence and budget impact very much drive reimbursement decisions in terms of pricing and restrictions, whereas in Italy, regional key opinion leader (KOL) support and additional local observational data are key.

Abstract
The prevalence of diabetes is dramatically increasing worldwide. The results of numerous epidemiological studies indicate that diabetic population is not only at increased risk of cardiovascular complications, but also at substantially higher risk of many forms of malignancies. The use of metformin, the most commonly prescribed drug for type 2 diabetes, was repeatedly associated with the decreased risk of the occurrence of various types of cancers, especially of pancreas and colon and hepatocellular carcinoma. This observation was also confirmed by the results of numerous meta-analyses. There are however, several unanswered questions regarding the exact mechanism of the anticancer effect of metformin as well as its activity against various types of cancer both in diabetic and nondiabetic populations. In the present work we discuss the proposed mechanism(s) of anticancer effect of metformin and preclinical and clinical data suggesting its anticancer effect in different populations.

Abstract
The present paper deals with the problem of evaluating empirical evidence for therapeutic decisions in medicine. The article discusses the views of Nancy Cartwright and John Worrall on the function that randomization plays in ascertaining causal relations with reference to the therapies applied. The main purpose of the paper is to present a general idea of alternative method of evaluating empirical evidence. The method builds on data analysis that makes use of rough set theory. The first attempts to apply the method show that it is an interesting alternative to randomized controlled trials.

Abstract
The reimbursement landscape for new and innovative diabetes devices in Europe is very heterogeneous and nontransparent, with each country employing different mechanisms, pathways, and requirements. This article provides an overview of how diabetes device reimbursement works in the outpatient setting in the five major European Union markets (France, Germany, Italy, Spain, and the United Kingdom; the EU-5). It will be of particular interest to manufacturers of innovative devices. Markets are first categorized as either a centralized or a regionalized reimbursement decision-making system, and implications for device reimbursement are explored. In the second part, specific requirements and success factors for wide reimbursement in the EU-5 are analyzed in detail. Gaining early acceptance by the main influencers (key opinion leaders and payers) is the first step. Equally important is the provision of convincing evidence, be this clinical, health-economic (cost-effectiveness), or a demonstration of cost savings (budget impact). In some countries, local usage data may be a requirement as well. Lastly, as payers' willingness to pay stems directly from their perceived value of a device, a key success factor and a necessary precondition for manufacturers is to set the right price.

Abstract
Besides demonstrated efficacy, selective serotonin reuptake inhibitors (SSRIs) hold other advantages over earlier antidepressants such as greater tolerability and a wider range of clinical applications. However, there is a growing body of clinical evidence which suggests that SSRIs could, in some cases, be associated with a withdrawal reaction upon cessation of regular use. In addition to sensory and gastrointestinal-related symptoms, the somatic symptoms of the SSRI discontinuation syndrome include dizziness, lethargy, and sleep disturbances. Psychological symptoms have also been documented, usually developing within 1–7 days following SSRI discontinuation. The characteristics of the discontinuation syndrome have been linked to the half-life of a given SSRI, with a greater number of reports emerging from paroxetine compared to other SSRIs. However, many aspects of the neurobiology of the SSRI discontinuation syndrome (or SSRI withdrawal syndrome) remain unresolved. Following a comprehensive overview of the clinical evidence, we will discuss the underlying pathophysiology of the SSRI discontinuation syndrome and comment on the use of animal models to better understand this condition.

Abstract
Introduction: The antiretroviral treatment paradigm for human immunodeficiency virus-1 (HIV-1) infection has undergone a significant change with the addition of a new class of therapeutic agents targeting HIV-1 integrase (IN). IN inhibitors prevent the integration of viral DNA into the human genome and terminate the viral life cycle. As the first member of this new class of anti-HIV drugs, raltegravir has shown promising results in the clinic. Aims: To review the emerging evidence for the use of the IN inhibitor raltegravir in the treatment of HIV-1 infection. Evidence review: Strong evidence shows that raltegravir is effective in reducing the viral load to less than 50 copies/mL and increasing CD4 cell count in treatment-experienced patients with triple-drug class-resistant HIV-1 infection. Substantial evidence also indicates that while raltegravir is able to achieve treatment response in patients with drug-resistant HIV-1, it is susceptible to development of resistance. Raltegravir should be used with at least one other active drug. In addition to its use in salvage therapy upon failure of first-line antiretroviral treatment, a raltegravir-based treatment regimen may also be effective as initial therapy. Substantial evidence also shows that raltegravir-based treatment regimen is well tolerated with minimal clinically severe adverse events and toxicities. Modeling studies suggest a cost-effectiveness of US$21,339 per quality-adjusted life year gained with raltegravir use, though further direct evidence on quality of life and cost-effectiveness is needed. Place in therapy: Raltegravir shows significant and sustained virologic and immunologic response in combination with other antiretrovirals in treatment-experienced HIV-1 infected patients who show evidence of viral replication or multidrug-resistant HIV-1 strains, without any significant tolerability issues.
