The aim of this review is to systematically review the evidence whether proper nutrition has a positive impact on the prevention or decline of depressive symptoms among elderly people. In addition, possible connections between nutrition, microbiome, and serotonin molecules and its tryptophan precursor are discussed. The methodology follows the PRISMA guidelines, including the PRISMA flow chart. The authors systematically reviewed peer-review, English-written articles published in Web of Science and PubMed between 2013 and 2018. The findings of six original articles, detected on the set inclusion and exclusion criteria, indicate that there is an association between nutrition and depressive symptoms in the target group, i.e., that proper nutrition has a positive impact on the prevention or reduction of depressive symptoms among elderly people. The findings also reveal that there is a considerable correlation between the intakes of vitamin B and a decrease in the prevalence of depressive symptoms. Furthermore, sufficient nutrient intake of tryptophan appears to be an important factor in terms of nutrition and serotonin levels in the body. The authors consider it important to explore associations between the overall dietary intake and depression since diets are not consumed as individual nutrients. Returning to preventive approaches seems to be a rational way to promote the mental health of seniors. Future studies thus need to include interdisciplinary collaboration: from a good diagnosis of the disease by a psychiatrist, through an analysis of the need for nutrient metabolism by a biochemist to the development of a nutritional plan by a nutritional therapist. The limitations of this review consist in a relatively small number of the studies on this topic, including just few randomized controlled trials, which are a guarantee of efficacy and objectivity in comparison with cross-sectional studies.

Meta-Analysis
BACKGROUND
Orally administered small-molecule drugs including tyrosine kinase 2 (TYK2) inhibitors and phosphodiesterase 4 (PDE4) inhibitors are new candidates for systemic therapy in plaque psoriasis. However, no previous articles evaluated the benefit and risk profile of TYK2 and PDE4 inhibitors in psoriasis.
OBJECTIVES
The objective of this study was to compare the efficacy and safety of oral small-molecule drugs, including TYK2 and PDE4 inhibitors, in treating moderate-to-severe plaque psoriasis.
METHODS
PubMed, Embase, and Cochrane library were searched for eligible randomized clinical trials (RCTs). Response rates for a 75% reduction from baseline in Psoriasis Area and Severity Index (PASI-75) and Physician's Global Assessment score of 0 or 1 (PGA 0/1) were used for efficacy assessment. Safety was evaluated with the incidence of adverse events (AEs). A Bayesian multiple treatment network meta-analysis (NMA) was performed.
RESULTS
In total, 13 RCTs (five for TYK2 inhibitors and eight for PDE4 inhibitors) involving 5274 patients were included. The study found that deucravacitinib at any dose (except for 3 mg QOD), ropsacitinib (200 and 400 mg QD), and apremilast (20 and 30 mg BID) had higher PASI and PGA response rates than placebo. In addition, deucravacitinib (3 mg BID, 6 mg QD, 6 mg BID, and 12 mg QD), and ropsacitinib (400 mg QD) showed superior efficacy than apremilast (30 mg BID). In terms of safety, deucravacitinib or ropsacitinib at any dose did not lead to a higher incidence of AEs than apremilast (30 mg BID). The ranking analysis of efficacy revealed that deucravacitinib 12 mg QD and deucravacitinib 3 mg BID had the highest chance of being the most effective oral treatment, followed by deucravacitinib 6 mg BID and ropsacitinib 400 mg QD.
CONCLUSIONS
Oral TYK2 inhibitors demonstrated satisfactory performance in treating psoriasis, surpassing apremilast at certain doses. More large-scale, long-term studies focusing on novel TYK2 inhibitors are needed.

Biologics and small-molecule drugs have become increasingly accepted worldwide in the treatment of axial spondyloarthritis (axSpA), including ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA). However, a quantitative multiple comparison of their efficacy and safety is lacking. This study aims to provide an integrated assessment of the relative benefits and safety profiles of these drugs in axSpA treatment. We included randomized clinical trials that compared biologics and small-molecule drugs in the treatment of axSpA patients. The primary outcomes assessed were efficacy, including the Assessment of SpondyloArthritis International Society (ASAS) improvement of 20% (ASAS20) and 40% (ASAS40). Safety outcomes included treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs). We used the surface under the cumulative ranking (SUCRA) curve value and ranking plot to evaluate and rank clinical outcomes and safety profiles of different treatments. The two-dimensional graphs were illustrated to visually assess both the efficacy (horizontal axis) and safety (vertical axis) of each intervention. Our analysis included 57 randomized clinical trials involving a total of 11,787 axSpA patients. We found that seven drugs (TNFRFc, TNFmAb, IL17Ai, IL17A/Fi, IL17RAi, JAK1/3i, and JAK1i) were significantly more effective in achieving ASAS20 response compared to the placebo (PLA). Except for IL17RAi, these drugs were also associated with higher ASAS40 responses. TNFmAb demonstrated the highest clinical response efficacy among all the drugs. Subgroup analyses for AS and nr-axSpA patients yielded similar results. IL17A/Fi emerged as a promising choice, effectively balancing efficacy and safety, as indicated by its position in the upper right corner of the two-dimensional graphs. Our findings highlight TNFmAb as the most effective biologic across all evaluated efficacy outcomes in this network meta-analysis. Meanwhile, IL17A/Fi stands out for its lower risk and superior performance in achieving a balance between efficacy and safety in the treatment of axSpA patients.

Meta-Analysis Comparative Study
BACKGROUND
The comparative efficacy of biologics and small-molecule inhibitors in treating palmoplantar psoriasis (PP) and palmoplantar pustulosis (PPP) remains uncertain.
OBJECTIVE
The aim was to perform a systematic review and network meta-analysis (NMA) to compare the efficacy of biologics and small-molecule inhibitors for the treatment of PP and PPP.
METHODS
MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were searched for eligible studies from inception to May 13, 2023. This NMA was conducted and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension Statement for Network Meta-Analyses guidelines. Frequentist random-effects models NMA was performed with the surface under the cumulative ranking curve calculated for ranking. Our primary outcome was the proportion of patients achieving a clear/minimal Palmoplantar Psoriasis/Pustulosis Physician Global Assessment score (PPPGA 0/1 or PPPPGA 0/1) response at 12-16 weeks. Secondary outcomes consisted of the percentage of overall improvement in palmoplantar score and of improvement ≥ 75%, at 12-16 weeks.
RESULTS
The study comprised a total of 29 randomized controlled trials (RCTs), involving 4798 psoriasis patients with palmoplantar diseases. For PP, 16 RCTs with nine different treatments, including adalimumab, apremilast, bimekizumab, etanercept, guselkumab, infliximab, ixekizumab, secukinumab, and ustekinumab were included for the analysis. In the NMA of PP, secukinumab 300 mg ranked highest (odds ratio [OR] 33.50, 95% confidence interval [CI] 4.37-256.86) in achieving PPPGA 0/1, followed by guselkumab 100 mg (OR 18.68, 95% CI 10.07-34.65). In the case of PPP, seven RCTs with six treatments, including apremilast, etanercept, guselkumab, imsidolimab, spesolimab, and ustekinumab, were included for the analysis. In the NMA of PPP, although no treatment demonstrated a significant difference compared to placebo in achieving PPPPGA 0/1, guselkumab 100 mg showed the greatest statistically significant improvement in the palmoplantar score (weighted mean difference 31.73, 95% CI 19.89-43.57) as a secondary outcome.
CONCLUSION
Among all available biologics and small-molecule inhibitors, secukinumab 300 mg and guselkumab 100 mg had the most favorable efficacy in treating PP and PPP, respectively.

Review
Power generation by converting energy from the ambient environment has been considered a promising strategy for developing decentralized electrification systems to complement the electricity supply for daily use. Wet gases, such as water evaporation or moisture in the atmosphere, can be utilized as a tremendous source of electricity by emerging power generation devices, that is, moisture-enabled-electric nanogenerators (MEENGs). As a promising technology, MEENGs provided a novel manner to generate electricity by harvesting energy from moisture, originating from the interactions between water molecules and hydrophilic functional groups. Though the remarkable progress of MEENGs has been achieved, a systematic review in this specific area is urgently needed to summarize previous works and provide sharp points to further develop low-cost and high-performing MEENGs through overcoming current limitations. Herein, the working mechanisms of MEENGs reported so far are comprehensively compared. Subsequently, a systematic summary of the materials selection and fabrication methods for currently reported MEENG construction is presented. Then, the improvement strategies and development directions of MEENG are provided. At last, the demonstrations of the applications assembled with MEENGs are extracted. This work aims to pave the way for the further MEENGs to break through the performance limitations and promote the popularization of future micron electronic self-powered equipment.

Review
BACKGROUND
The incidence of premature atherosclerotic cardiovascular disease in familial hypercholesterolemia (FH) is high. In recent years, novel therapeutic modalities have shown significant lipid-lowering ability. In this paper, we summarize the recent developments in novel therapies for FH via the treatment of different targets and discuss the characteristics of each targeted therapy. Based on the process of protein synthesis, we attempt to summarize the direct-effect targets including protein, RNA, and DNA.
METHODS
For this systematic review, relevant studies are assessed by searching in several databases including PubMed, Web of Science, Scopus, and Google Scholar. The publications of original researches are considered for screening.
RESULTS
Most drugs are protein-targeted such as molecule-based and monoclonal antibodies, including statins, ezetimibe, alirocumab, evolocumab, and evinacumab. Both antisense oligonucleotide (ASO) and small interfering RNA (siRNA) approaches, such as mipomersen, vupanorsen, inclisiran, and ARO-ANG3, are designed to reduce the number of mRNA transcripts and then degrade proteins. DNA-targeted therapies such as adeno-associated virus or CRISPR-Cas9 modification could be used to deliver or edit genes to address a genetic deficiency and improve the related phenotype.
CONCLUSION
While the therapies based on different targets including protein, RNA, and DNA are on different stages of development, the mechanisms of these novel therapies may provide new ideas for precision medicine.

Meta-Analysis Review
OBJECTIVE
This study aimed to explore the efficacy and safety of small-molecule antivirals for treating coronavirus disease 2019 (COVID-19).
METHODS
Seven databases were searched from their inception to 01 June 2023. The risk of bias in randomised controlled trials and retrospective studies was evaluated individually using the Cochrane risk-of-bias tool and Newcastle Ottawa Scale.
RESULTS
In total, 160 studies involving 933 409 COVID-19 patients were evaluated. Compared with placebo or standard of care, proxalutamide demonstrated remarkable efficacy in reducing mortality rates, hospitalisation rates, serious adverse events, and the need for mechanical ventilation. Furthermore, it significantly enhanced both the rate of clinical improvement and expedited the duration of clinical recovery when compared with control groups. In patients with mild-to-moderate COVID-19, proxalutamide exhibited the above advantages, except for mortality reduction. Triazavirin was the most effective treatment for reducing the time required for viral clearance and improving the discharge rate. Leritrelvir and VV116 were ranked first in terms of enhancing the viral clearance rate on days 7 and 14, respectively. Molnupiravir was the most effective treatment for reducing the need for oxygen support. Overall, these findings remained consistent across the various subgroups.
CONCLUSIONS
A thorough evaluation of effectiveness, applicable to both mild-to-moderate and unstratified populations, highlights the specific advantages of proxalutamide, nirmatrelvir/ritonavir, triazavirin, azvudine, molnupiravir, and VV116 in combating COVID-19. Additional clinical data are required to confirm the efficacy and safety of simnotrelvir/ritonavir and leritrelvir. The safety profiles of these antivirals were deemed acceptable.

Review
Mesenchymal Stem Cells (MSCs) are multipotent non-hematopoietic stromal cells found in different body tissues such as bone marrow, adipose tissue, periosteum, Wharton's jelly, umbilical cord, blood, placenta, amniotic fluid, and skin. The biological behavior of MSCs depends mainly on their interaction with the microenvironment in which they are found, whose quality deeply influences the regenerative and immunomodulatory properties of these cells. Several studies confirm the interaction between MSCs and inflammatory microenvironment in the pathogenesis of psoriasis, designating MSCs as an important factor driving psoriasis development. This review aims to describe the most recent evidence on how the inflammatory microenvironment that characterizes psoriasis influences the homeostasis of MSCs and how they can be used to treat the disease.

Review
Targeted protein degradation (TPD) has emerged as a promising therapeutic approach with potential advantages over traditional occupancy-based inhibitors in terms of dosing, side effects and targeting "undruggable" proteins. Targeted degraders can theoretically bind any nook or cranny of targeted proteins to drive degradation. This offers convenience versus the small-molecule inhibitors that must function in a well-defined pocket. The degradation process depends mainly on two cell self-destruction mechanisms, namely the ubiquitin-proteasome system and the lysosomal degradation pathway. Various TPD strategies (e.g., proteolytic-targeting chimeras, molecular glues, lysosome-targeting chimeras, and autophagy-targeting chimeras) have been developed. These approaches hold great potential for targeting dysregulated proteins, potentially offering therapeutic benefits. In this article, we systematically review the mechanisms of various TPD strategies, potential applications to drug discovery, and recent advances. We also discuss the benefits and challenges associated with these TPD strategies, aiming to provide insight into the targeting of dysregulated proteins and facilitate their clinical applications.

Review
Classic small molecule inhibitors that directly target pathogenic proteins typically rely on the accessible binding sites to achieve prolonged occupancy and influence protein functions. The emerging targeted protein degradation (TPD) strategies exemplified by PROteolysis TArgeting Chimeras (PROTACs) are revolutionizing conventional drug discovery modality to target proteins of interest (POIs) that were categorized as "undruggable" before, however, these strategies are limited within intracellular POIs. The novel new degrader technologies such as LYsosome-TArgeting Chimaeras (LYTACs) and Antibody-based PROTACs (AbTACs) have been successfully developed to expand the scope of TPD to extracellular and membrane proteins, fulfilling huge unmet medical needs. Here, we systematically review the currently viable protein degradation strategies, emphasize that LYTACs and AbTACs turn a new avenue for the development of TPD, and highlight the potential challenges and directions in this vibrant field.
