Reviews on recent clinical trials最新文献

Alzheimer's disease (AD) is a multidimensional, complex condition that affects individuals all over the world. Despite decades of experimental and clinical research that has revealed various processes, many concerns concerning the origin of Alzheimer's disease remain unresolved. Despite the notion that there isn't a complete set of jigsaw pieces, the growing number of public data-sharing initiatives that collect biological, clinical, and lifestyle data from those suffering from Alzheimer's disease has resulted in virtually endless volumes of knowledge about the disorder, far beyond what humans can comprehend. Furthermore, combining Big Data from multi- -omics research gives a chance to investigate the pathophysiological processes underlying the whole biological spectrum of Alzheimer's disease. To improve knowledge on the subject of Alzheimer's disease, Artificial Intelligence (AI) offers a wide variety of approaches for evaluating complex and significant data. The introduction of next-generation sequencing and microarray technologies has resulted in significant growth in genetic data research. When it comes to assessing such complex projects, AI technology beats conventional statistical techniques of data processing. This review focuses on current research and potential challenges for AI in Alzheimer's disease research. This article, in particular, examines how AI may assist healthcare practitioners with patient stratification, estimating an individual's chance of AD conversion, and diagnosing AD using computer-aided diagnostic methodologies. Ultimately, scientists want to develop individualized, efficient medicines.

Different levels of residual drugs can be monitored within a relatively safe range without causing harm to human health if the appropriate dosing methodology is considered and the drug withdrawal period is controlled during poultry and livestock raising. Antimicrobials are factors that can suppress the growth of microorganisms, and antibiotic residues in livestock farming have been considered as a potential cause of antimicrobial resistance in animals and humans. Antimicrobial drug resistance is associated with the capability of a microorganism to survive the inhibitory effects of the antimicrobial components. Antibiotic residue presence in chicken is a human health concern due to its negative effects on consumer health. Neglected aspects related to the application of veterinary drugs may threaten the safety of both humans and animals, as well as their environment. The detection of chemical contaminants is essential to ensure food quality. The most important antibiotic families used in veterinary medicines are β-lactams (penicillins and cephalosporins), tetracyclines, chloramphenicols, macrolides, spectinomycin, lincosamide, sulphonamides, nitrofuranes, nitroimidazoles, trimethoprim, polymyxins, quinolones, and macrocyclics (glycopeptides, ansamycins, and aminoglycosides). Antibiotic residue presence is the main contributor to the development of antibiotic resistance, which is considered a chief concern for both human and animal health worldwide. The incorrect application and misuse of antibiotics carry the risk of the presence of residues in the edible tissues of the chicken, which can cause allergies and toxicity in hypersensitive consumers. The enforcement of the regulation of food safety depends on efficacious monitoring of antimicrobial residues in the foodstuff. In this review, we have explored the rapid detection of drug residues in broilers.

Immune checkpoint inhibitor therapy has become the established method of treatment for various types of cancers, consequently introducing a spectrum of side effects referred to as immune- mediated adverse events, affecting almost every organ, including the reproductive system. Moreover, very little clinical data is available that suggests the detrimental effect of immune checkpoint inhibitor therapy on fertility, sexual health, or potential pregnancies. In this manuscript, we reviewed the impact of immunotherapy on male and female fertility and its effect on sexual health. Patients undergoing systemic treatment with immunotherapy often experience sexual dysfunction, decreased sexual drive, erectile dysfunction, and a decline in vaginal lubrication. Fertility-desiring patients who do not receive adequate counseling may ultimately face a higher likelihood of developing anxiety, depression, and a decreased quality of life post-treatment. Therefore, it is crucial to address the reproductive consequences of planned treatment, disseminate knowledge about novel treatments and preventive measures for reproductive side effects, and provide guidance on fertility preservation. Individuals experiencing secondary reproductive dysfunction due to the tumor or its treatment should receive proactive treatment for the underlying condition and be offered hormone replacement therapy.

Background: It has been proposed that colchicine may have the potential to prevent cardiovascular and cerebrovascular dysfunctions.

Objective: This study evaluated the impact of colchicine on preventing recurrent stroke in patients with both ischemic stroke (IS) and atrial fibrillation (AF).

Methods: A randomized, double-blinded, placebo-controlled trial was conducted at Golestan Hospital (Ahvaz, Iran) over one year, involving IS patients with AF. Demographic and clinical data were collected from the participants, who were then assigned to either the intervention or placebo groups. The experimental group was administered colchicine at a dosage of 0.05 mg twice daily for one year, while the control group received a placebo at a comparable dosage over the same timeframe.

Results: In one year, 108 patients completed the study. There were 55 patients in the intervention group and 53 patients in the placebo group. During the second trimester of the trial, three patients in the colchicine group and 10 patients in the placebo group experienced recurrent strokes. Gastrointestinal issues were the most commonly reported complications (33 cases) among the two groups, followed by myalgia (8 patients). There were significant differences in the frequency of recurrent stroke and serum levels of C-reactive protein (CRP) between the colchicine and placebo groups (p < 0.05) after intervention.

Conclusion: In this study, colchicine was effective in reducing recurrent stroke and CRP levels in IS patients with AF compared to the control group. Further randomized controlled trials with larger sample sizes and extended durations are recommended to validate the results of this trial.

Introduction/objective: Significant advancements have been achieved with the use of targeted molecular therapies for the treatment of Soft Tissue Sarcomas (STS). However, data remain scarce about the potential benefits and toxicity of this therapeutic option. In this narrative review, we aim to better clarify the potential wound healing complications in STS patients undergoing neoadjuvant (NA) radiotherapy (RT) combined with targeted therapies.

Methods: We used the PubMed database to retrieve journal articles, and the inclusion criteria were all studies that illustrated the potential RT toxicity, combined with targeted therapies, in the NA setting of STS patients.

Results: Our search resulted in seven studies that fulfilled the inclusion criteria. Delayed wound complication rates were observed similarly to RT alone, while one study reported intolerable toxicity without referring specifically to wound complications.

Conclusion: The combination of RT with targeted therapies in STS seems to be effective and well tolerated. Due to the lack of studies with a high level of evidence, further research is required to enhance the existing knowledge for its potential value in this field.

Background: Bariatric surgery is one of the effective therapeutic options for people with obesity and obesity-related co-morbidities. In addition to weight-related co-morbid diseases, including diabetes, hypertension, and hypercholesterolemia, non-alcoholic fatty liver disease (NAFLD) is common in patients with morbid obesity. Bariatric surgery is one of the therapeutic options in the management of NAFLD. Hence, this review focused on the potential role of bariatric surgery on hepatic elasticity measured through shear wave elastography.

Methods: A systematic literature search was performed, and the studies regarding heterogeneity were evaluated using the random-effects model.

Results: The meta-analysis on 6 trials (3-12 months follow-up) including 350 participants showed a significant reduction of liver elasticity after surgery (WMD: -1.149, 95% CI: -1.767, -0.532, p < 0.001; I2:81.55%).

Conclusion: Bariatric surgery is associated with decreased liver elasticity. This improvement could be related to weight loss or other mechanisms of bariatric surgery.

Background: The aim of this study is to synthesize the existing evidence on various palliative care (PC) models for cancer patients. This effort seeks to discern which facets of PC models are suitable for various patient cohorts, elucidate their mechanisms, and clarify the circumstances in which these models operate.

Methods: A comprehensive search was performed using MeSH terms related to PC and cancer across various databases. The Preferred Reporting Items for Systematic Reviews and a comprehensive evidence map were also applied.

Results: Thirty-three reviews were published between 2009 and 2023. The conceptual PC models can be classified broadly into time-based, provider-based, disease-based, nurse-based, issue-based, system-based, team-based, non-hospice-based, hospital-based, community-based, telehealth-based, and setting-based models. The study argues that the outcomes of PC encompass timely symptom management, longitudinal psychosocial support, enhanced communication, and decision-making. Referral methods to specialized PC services include oncologist-initiated referral based on clinical judgment alone, via referral criteria, automatic referral at the diagnosis of advanced cancer, or referral based on symptoms or other triggers.

Conclusion: The gold standard for selecting a PC model in the context of oncology is a model that ensures broad availability of early PC for all patients and provides well-timed, scheduled, and specialized care for patients with the greatest requirement.

Background and objective: Abdominal pain is a frequent reason for admission to the Emergency Department. It may be a symptom of an underlying "organic" disease or a "functional" manifestation without an underlying anatomic or physiologic alteration. The evaluation of patients with abdominal pain is a challenge for the emergency physician and the selection of patients for second-level radiological examinations or endoscopic procedures is not always easy to perform. Faecal calprotectin could be a useful diagnostic marker to distinguish between "organic" or "functional" form and its determination could be helpful to select patients for further examinations in the context of an emergency setting.

Materials and methods: This is an observational and retrospective study on 146 patients with abdominal pain and/or diarrhea (with or without rectal bleeding) admitted to the Emergency Department of Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, who collected a fecal sample to evaluate fecal calprotectin. We evaluated and correlated the level of fecal calprotectin with the final diagnosis they received.

Results: 50/146 patients (34,24%) received a diagnosis of acute diverticulitis, in particular, 14/50 (28%) were complicated and 36/50 (72%) were uncomplicated; 4/146 (2,7%) were cholangitis, 32/146 (21,9%) were colitis, 6/146 (4,1%) gastritis, 42/146 (28,7%), Irritable bowel syndrome and 12/146 (8,2%) Inflammatory bowel disease. For the differential diagnosis between Irriable or inflammatory bowel diseses, our study showed a VPP and a VPN of 100% meanwhile for the differential diagnosis between Acute complicated and uncomplicated diverticulitis, our study showed a VPP of 40% and a VPN of 84%.

Conclusion: In the emergency setting, faecal calprotectin could be a helpful marker to select patients with abdominal pain who need second-level radiological examinations or endoscopic procedures, guiding the emergency physician in the evaluation of such a complex and wideranging symptom.

Background: Functional dyspepsia (FD) is felt as a discomfort or pain on the center line or upper abdomen. In this study, we aimed to compare the effects of Govarcin herbal capsule and Metoclopramide for alleviating gastrointestinal symptoms in patients with FD.

Methods: Totally, 106 patients enrolled in a double-blind, clinical trial study. The participants had FD and were divided into two groups receiving Govarcin and Metoclopramide by block randomization. The patients were treated for four weeks, taking one Govarcin capsule or Metoclopramide tablet after each meal. The rate of improvement in patients was assessed by mitigation of clinical symptoms, including epigastric pain, fullness, discomfort, nausea, vomiting and heartburn. Also, before and after intervention, we used Nepin questionnaire and ROME III. SPSS statistics 25 software was used for data analyzing.

Results: Clinical symptom score changes between Govarcin and Metoclopramide patients' groups showed that there was no significant difference in any of the clinical symptom scores (except for heartburn, p-value=0.012) between the study groups. Nepean score in Govarcin group before and after treatment were 19.3±4.8 and 8.9±2.8, respectively (p-value<0.001). For Metoclopramide group, these values were 19.8±3.5 and 9.4±2.1 respectively (p-value<0.001). No significant difference was found in terms of Nepean score between the Govarcin and Metoclopramide groups (p-value=0.995).

Conclusion: Govarcin herbal capsule can be used to remedy symptoms in patients with FD. It seems that Govarcin is as effective as Metoclopramide in fighting symptoms of FD as no significant difference in efficacy has been demonstrated between them.
