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.

Review
Mid- and long-term (at least 12 months) follow-up of patients with spinal muscular atrophy (SMA) treated with nusinersen, onasemnogene abeparvovec, risdiplam or combination therapies: A systematic review of real-world study data.
OBJECTIVES
This systematic review aimed to assess mid- and long-term (at least 12 months) real-world study data from all types of spinal muscular atrophy (SMA) patients treated with any of the approved drugs or combination therapies.
METHODS
A systematic literature search was carried out in five databases. Two authors selected the studies based on pre-defined selection criteria and independently graded the risk of bias at study level.
RESULTS
Five hundred forty-six records were identified in the literature search and 22 studies (in 26 publications) were included in the analysis. Nusinersen, onasemnogene abeparvovec and combination therapies improved motor endpoints in SMA type 1 patients. SMA type 2 to type 4 patients treated with nusinersen showed stabilisation or small improvements in motor endpoints with some deterioration observed. Quality of life endpoints, such as respiratory and nutritional support were poorly reported on. Drug-related adverse events occurred rarely in all types of SMA patients with all assessed drugs. Mid- and long-term studies on risdiplam could not be identified.
CONCLUSIONS
The large quantity of missing data and heterogeneity of studies hinder comparability. Although stability and further improvement on the long-term is still uncertain, the results from the included evidence, as well as from pivotal trials show a striking contrast to the natural progression of the disease.

Review
Aptamers have been the subject of more than 144 000 papers to date. However, there has been a growing concern that discrepancies in the reporting of aptamer research limit the reliability of these reagents for research and other applications. These observations noting inconsistencies in the use of our RNA antilysozyme aptamer served as an impetus for our systematic review of the reporting of aptamer sequences in the literature. Our detailed examination of the literature citing the RNA antilysozyme aptamer revealed that 93% of the 61 publications reviewed reported unexplained altered sequences with 96% of those using DNA variants. The 10 most cited aptamers were examined using a standardized methodology in order to categorize the extent to which the sequences themselves and altered sequences were adequately described in the literature. Our review of 780 aptamer publications spanned decades, multiple journals, and research groups and revealed that 41% of the papers reported unexplained sequence alterations or omitted sequences. We identified 10 common categories of sequence alterations including deletions, substitutions, and additions, among others. Overall, our findings can be used as a starting point for building better practices in author submissions and publication standards, elevating the rigor and reproducibility of aptamer research.

Meta-Analysis
PURPOSE
Familial celiac disease syndrome (FCS) is a form of hypertriglyceridemia (HTG) caused by the accumulation of celiac particles. Currently, volanesorsen is considered to be used to treat patients with FCS and HTG to improve symptoms. To evaluate the effect of volanesorsen on lipid metabolism in patients with FCS, we performed a systematic evaluation and meta-analysis.
METHODS
A systematic search of PubMed, Embase, ClinicalTrials.gov, and the Cochrane Library was conducted, and the bibliographies of original articles were checked manually. The quality of the studies was assessed using the Cochrane Risk of Bias tool.
RESULTS
Four randomized, controlled trials involving 246 patients were analyzed in this study. Patients treated with volanesorsen showed (MD = -78.85%; 95% CI = -96.04 to -61.65, P = 0.67, I = 0%) decrease in TG and (MD = -80.08%; 95% CI = -90.02 to -71.54, P = 0.25, I = 29%) decrease in ApoC-III levels compared to patients in the placebo group showing a significant decrease. In addition, HDL-C increased (MD = 46.01% 95% CI = 41.03 to 50.99, P = 0.41, I = 0%), NHDL-C decreased (MD = -32.12%; 95% CI = -44.39 to -19.85, P = 0.11, I = 55%), VLDL-C decreased (MD = -65.88%; 95% CI = -83.97 to -47.79, P = 0.71, I = 0%), apo A1 increased (MD = 13.12%; 95% CI = 7.83 to 18.40, P = 0.72, I = 0%), and apoB increased (MD = 7.94 %; 95% CI = -1.90 to 17.78, P = 0.54, I = 0%) all suggest that volanesorsen has an overall FCS with a therapeutic effect. However, LDL-C increased (MD = 99.59%; 95% CI = 69.19 to 130.00, P = 0.61, I = 0%) and apo B48 decreased (MD = 82.89%; 95% CI = -100.88 to -64.91, P = 0.42, I = 0%), showing an inverse effect, suggesting that volanesorsen's did not target all proteins of lipid metabolism.

Meta-Analysis Review
: Spinal muscular atrophy (SMA) is a neurodegenerative disease that leads to progressive proximal muscle weakness and muscle atrophy. To assess the beneficial and adverse effects of nusinersen, a promising intervention for SMA, we conducted a systematic search and meta-analysis of the published randomized control trials (RCTs) of nusinersen for SMA. : Utilizing the Preferred Reporting for Systematic Review and Meta-Analysis (PRISMA), we searched PubMed, Scopus, Web of Science, Cochrane Central, and Clinicaltrials.gov from inception to 22 July 2021. : Three RCTs satisfying the inclusion and exclusion criteria covered 274 patients: 178 patients in the nusinersen group. Our results show a significant risk difference (RD) in the motor milestone response (RD: 0.51; 95% CI: 0.39, 0.62; < 0.00001) and improvement in the HINE-2 score (RD: 0.26; 95% CI: 0.12, 0.40; < 0.0003) in the nusinersen group compared to the control group. Moreover, a significant decrease in the risk ratio (RR) for severe adverse events (RR: 0.72; 95% CI: 0.57, 0.92; = 0.007) and any adverse event leading to treatment discontinuation (RR: 0.40; 95% CI: 0.22, 0.74; = 0.004) was observed. An insignificant result was found for any adverse effects (RR: 0.93; 95% CI: 0.97, 1.01; = 0.14) and for serious adverse effects (RR: 0.81; 95% CI: 0.60, 1.07; = 0.14). : This review provides evidence that nusinersen treatment was effective in treatment for infants with SMA and was associated with fewer severe adverse events; however, more RCTs are needed to establish evidence.

Meta-Analysis
Evidence for nusinersen administration in adult 5q spinal muscular atrophy (5q-SMA) patients is scarce and based on real-world observational data. The present systematic review and meta-analysis aimed to explore the efficacy and safety of nusinersen in patients older than 12 years of age with 5q-SMA. We searched MEDLINE, EMBASE, the Cochrane Library, and grey literature through April 2021. Cross-sectional studies, case reports, review articles, and studies with follow-up less than 6 months were excluded. We included 12 records (seven case-series, five cohorts) representing 11 population cohorts and enrolling 428 SMA patients. We observed statistically significant improvements on motor function Hammersmith Functional Motor Scale Expanded (HFMSE) and Revised Upper Limb Module (RULM) scores at the longest follow-up assessments [SMD = 0.17(95% CI 0.01-0.33), SMD = 0.22(95% CI 0.06-0.38), respectively]. HFMSE and RULM significant improvements were also detected at the subgroup analysis during 10 and 14 months. HFMSE and RULM amelioration occurred earlier in patients with SMA type 3 or 4 during short-term analysis (≤ 6 months). 6-min walk tests (6MWT) and pulmonary function tests did not change. Minimal clinically important differences in HFMSE and RULM were observed in 43.3% (95% CI 34.5-52.3) and 38.9% (95% CI 27.7-50.7), respectively. Severe adverse events were reported in 2% (95% CI 0-5.8). Treatment withdrawal rate was 3% (95% CI 0.5-6.6). Despite the low quality of evidence and the unmet need for randomized data to establish the safety and efficacy of nusinersen in adults, our meta-analysis confirms that nusinersen is a valuable treatment option for older patients with longer-disease duration.Trial registration: PROSPERO database CRD42020223109.

Meta-Analysis Review
BACKGROUND
Prevention of pressure ulcers (PU) is one of the most important indicators of the quality of patient care that may be influenced by the attitude of nurses. Nurses are responsible for maintaining the integrity of the skin and preventing its complications. The aim of this study was to assess the overall attitude of nurses on PU prevention based on their scores on the Attitude towards Pressure ulcer Prevention instrument (APuP).
METHODS
In this systematic review and meta-analysis, databases including Web of Science, Science Direct, PubMed, and Scopus were searched, using the following keywords: Pressure Ulcer, Pressure injury, Bedsore, Pressure Sore, Decubitus Ulcer, Attitude, and their possible combinations. Heterogeneity of studies was assessed with I index and Cochrane-Q test. Based on heterogeneity between the studies, the data were analyzed using a random effects model. All the analyses were performed using STATA v.16 software.
RESULTS
Twelve studies with a sample size of 7824 people were analyzed. The overall score of attitude towards pressure ulcer prevention was 70.84% (95% CI: 66.34-75.35) and the highest and lowest scores were related to the dimensions of individual priority (78.83%, 95% CI: 74.69-82.97) and competence (70.11%, 95% CI: 67.24-72.94), respectively. The percentage of the total score of attitude towards pressure ulcer prevention in nurses was higher than nursing students (72.15%, 95% CI: 67.10-77.20 vs. 67%, 95% CI: 53.80-80.20). Sensitivity analysis confirmed the stability of the results. Publication bias was significant (p = 0.036).
CONCLUSION
The attitude of nurses and nursing students towards the prevention of pressure ulcers was moderate, and providing the necessary training to these groups was essential.

Review
Alzheimer's disease (AD) is a heterogeneous degenerative brain disorder with a rising prevalence worldwide. The two hallmarks that characterize the AD pathophysiology are amyloid plaques, generated via aggregated amyloid β, and neurofibrillary tangle, generated via accumulated phosphorylated tau. At the post-transcriptional and transcriptional levels, the regulatory functions of non-coding RNAs, in particular long non-coding RNAs (lncRNAs), have been ascertained in gene expressions. It is noteworthy that a number of lncRNAs feature a prevalent role in their potential of regulating gene expression through modulation of microRNAs via a process called the mechanism of competing endogenous RNA (ceRNA). Given the multifactorial nature of ceRNA interaction networks, they might be advantageous in complex disorders (e.g., AD) investigations at the therapeutic targets level. We carried out scoping review in this research to analyze validated loops of ceRNA in AD and focus on ceRNA axes associated with lncRNA. This scoping review was performed according to a six-stage methodology structure and PRISMA guideline. A systematic search of seven databases was conducted to find eligible articles prior to July 2021. Two reviewers independently performed publications screening and data extraction, and quantitative and qualitative analyses were conducted. Fourteen articles were identified that fulfill the inclusion criteria. Studies with different designs reported nine lncRNAs that were experimentally validated to act as ceRNA in AD in human-related studies, including , , , , , , , , and . The / was the most frequent ceRNA pair. Among miRNAs, played a key role by regulating three different loops. Understanding the various aspects of this regulatory mechanism can help elucidate the unknown etiology of AD and provide new molecular targets for use in therapeutic and clinical applications.
