The Efficacy of Senna Bowel Preparation for Colonoscopy: A Systematic Review and Meta-analysis.

The quality of bowel preparation is an extremely important determinant of colonoscopy results. However, the efficacy of senna regimens in improving bowel cleanliness is uncertain. We conducted a systematic review and meta-analysis to synthesize data on whether using a senna bowel preparation regimen enhances the bowel cleanliness. We searched Web of Science Core Collection, MEDLINE, PubMed, Embase, Cochrane Library, and Scopus databases (from the inception to August 2021). The primary efficacy outcome was bowel cleanliness. Secondary outcomes included patient compliance, tolerance, and adverse events. Eleven trials fulfilled the inclusion criteria (3,343 patients. Overall, we found no significant differences in bowel cleanliness between the senna regimen and other bowel preparation regimens (odds ratio [95% confidence interval]: 1.02 [0.63, 1.67], p = 0.93). There was significant difference in tolerance (odds ratio [95% confidence interval]: 1.66 [1.08, 2.54], p = .02) and compliance (odds ratio [95% confidence interval]: 3.05 [1.42, 6.55], p = .004). The senna regimen yielded a significantly greater proportion of no nausea (odds ratio [95% confidence interval]: 1.84 [1.45, 2.32]) and vomiting (odds ratio [95% confidence interval]: 1.65 [0.81, 3.35]). Compared with other bowel preparation regimens, the senna regimen may be effective and safe in bowel cleaning before colonoscopy, with superior compliance and tolerance.

Effectiveness of Different Noninvasive Physiotherapy in Relieving Postlaparoscopic Shoulder pain: A Protocol for Systematic Review and Network Meta-Analysis.

Background: Shoulder pain is one of the most common symptoms after laparoscopic surgery, which seriously affects people's health and quality of life. Many clinical studies have shown that noninvasive physiotherapy is the most beneficial treatment for patients, but the best approach for various noninvasive physiotherapy is unclear. The purpose of this study protocol is to compare the effectiveness of different noninvasive physiotherapy in relieving postlaparoscopic shoulder pain (PLSP). Methods: We will search ten electronic databases including PubMed, Web of Science, Medline, Scopus, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), CNKI, WanFang Data and VIP databases from their inception to November 2023. We will select randomized controlled trials (RCTs) to evaluate the effectiveness of noninvasive physiotherapy on PLSP. Our primary outcome will be to measure the intensity of shoulder pain at 24 and 48 hours after the end of the noninvasive intervention in the included study. Secondary outcomes include incidence of shoulder pain at 24 and 48 hours, postoperative nausea / vomiting and incidence of other complications after noninvasive intervention. Then, standard network meta-analysis will be conducted using Review Manager 5.4 and STATA 18. Results: Our systematic review and network meta-analysis will identify the best noninvasive physiotherapy for PLSP patients. Conclusion: This systematic review will address the existing knowledge gap regarding best practice for relieving PLSP with noninvasive physiotherapy. The results of this network meta-analysis will help medical staff and patients choose the best method to relieve the PLSP. Furthermore, we hope that the results of this study will provide evidence-based for the improvement of guidelines and facilitate the decision sharing process.

Research hotspots and trends in postlaparoscopic shoulder pain from 2003 to 2023: A bibliometric analysis.

The incidence of postlaparoscopic shoulder pain has recently increased and has attracted increasing attention from clinical workers, but no study has performed bibliometric and visual analysis of the relevant literature. This study used bibliometric and visual analysis to conduct a comprehensive and systematic evaluation of postlaparoscopic shoulder pain to help researchers understand the latest global trends and hotspots and provide a reference for caregivers to carry out PLSP care interventions and research. Related studies on postlaparoscopic shoulder pain from 2003 to 2023 were retrieved from the Web of Science Core Collection. We analysed current research trends and hotspots in this field using VOSviewer and CiteSpace. A total of 2451 authors from 352 institutions in 50 countries published 464 studies related to postlaparoscopic shoulder pain. The United States was the country with the most publications and worked closely with other countries. Donmez Turgut was the researcher with the most published articles, while Bisgaard T had the most citations per article. The Journal of Surgical Endoscopy was cited most frequently, totalling 356 times. Through keyword significance analysis, we found that relieving postlaparoscopic shoulder pain in patients through integrated care interventions was an emerging research hotspot. This bibliometric and visual analysis provides a comprehensive review of studies related to postlaparoscopic shoulder pain. The current global research trend and hotspot is to alleviate postlaparoscopic shoulder pain through integrated care interventions, but the advantages of this approach are not outstanding. However, further research and global collaboration are still needed. Our findings can help researchers understand the current status of postlaparoscopic shoulder pain research and identify new directions for future research.

Emergency rescue of a patient with hemorrhagic shock caused by superior mesenteric artery rupture: A case report.

BACKGROUND: Superior mesenteric artery (SMA) injuries rarely occur during blunt abdominal injuries, with an incidence of < 1%. The clinical manifestations mainly include abdominal hemorrhage and peritoneal irritation, which progress rapidly and are easily misdiagnosed. Quick and accurate diagnosis and timely effective treatment are greatly significant in managing emergent cases. This report describes emergency rescue by a multidisciplinary team of a patient with hemorrhagic shock caused by SMA rupture. CASE SUMMARY: A 55-year-old man with hemorrhagic shock presented with SMA rupture. On admission, he showed extremely unstable vital signs and was unconscious with a laceration on his head, heart rate of 143 beats/min, shallow and fast breathing (frequency > 35 beats/min), and blood pressure as low as 20/10 mmHg (1 mmHg = 0.133 kPa). Computed tomography revealed abdominal and pelvic hematocele effusion, suggesting active bleeding. The patient was suspected of partial rupture of the distal SMA branch. The patient underwent emergency mesenteric artery ligation, scalp suture, and liver laceration closure. In view of conditions with acute onset, rapid progression, and high bleeding volume, key points of nursing were conducted, including activating emergency protocol, opening of the green channel, and arranging relevant examinations with various medical staff for quick diagnosis. The seamless collaboration of the multidisciplinary team helped shorten the preoperative preparation time. Emergency laparotomy exploration and mesenteric artery ligation were performed to mitigate hemorrhagic shock while establishing efficient venous accesses and closely monitoring the patient's condition to ensure hemodynamic stability. Strict measures were taken to avoid intraoperative hypothermia and infection. CONCLUSION: After 3.5 h of emergency rescue and medical care, bleeding was successfully controlled, and the patient's condition was stabilized. Subsequently, the patient was transferred to the intensive care unit for continuous monitoring and treatment. On the sixth day, the patient was weaned off the ventilator, extubated, and relocated to a specialized ward. Through diligent medical intervention and attentive nursing, the patient made a full recovery and was discharged on day 22. The follow-up visit confirmed the patient's successful recovery.

Efficacy and Tolerability of Two Different Low-Volume Split-Dose Polyethylene Glycol Electrolytes Solution Bowel Preparation for Morning Colonoscopy.

Methods: A total of 120 patients were randomized to receive either the control group (n = 64) or the experimental group (n = 65). Patients in the control group adopted the low-volume split-dose regimen one, and patients in the experimental group adopted the low-volume split-dose regimen two. Those randomized to regimen one were instructed to take 0.75 L PEG two hours after dinner the day before the colonoscopy and 1.5 L PEG 4 hours before the colonoscopy. Patients assigned to regimen two were invited to consume 1.5 L PEG two hours after dinner the day before the colonoscopy and 0.75 L PEG 4 hours before the colonoscopy. The quality of bowel preparation, rated according to a Boston Bowel Preparation Scale (BBPS), represented the primary outcome measure. Tolerability, satisfaction, and lesions detection rated were secondary outcomes. Results: There was no significant difference between the transverse colon and right colon scores between the two groups (P > 0.05). The low-volume split-dose regimen two showed a higher success rate for cleansing of the right colon and overall colon (P < 0.05). For the comparison of the patients' bowel tolerance, there were no statistical differences between the two groups regarding thirst, abdominal pain or abdominal discomfort, abdominal distension, dizziness or headache, anal discomfort, and sleep disturbance (P > 0.05). However, regimen two had significantly less nausea, vomiting, and fatigue than regimen one (24.62% vs. 42.19%, P=0.034; 10.77% vs. 25.00%, P=0.035; 6.15% vs. 21.88%, P=0.010, respectively). Patient-reported satisfaction and willingness to repeat the bowel preparation were significantly higher for low-volume split-dose regimen two than for low-volume split-dose regimen one (P=0.011; P=0.015). Conclusions: In early morning colonoscopies, the bowel-cleansing efficacy and patient tolerability of low-volume split-dose regimen two were superior to low-volume split-dose regimen one.

The Effectiveness of Drying on Residual Droplets, Microorganisms, and Biofilms in Gastrointestinal Endoscope Reprocessing: A Systematic Review.

BACKGROUND: Despite endoscope reprocessing, residual droplets remain in gastrointestinal endoscope working channels. Inadequate drying of gastrointestinal endoscope working channels may promote microbial reproduction and biofilm formation, increasing the risk of infection in patients. This review was designed to provide the current status of gastrointestinal endoscope drying, emphasize the importance of gastrointestinal endoscope drying, and evaluate the effectiveness of different drying methods of gastrointestinal endoscope in reducing residual droplets and microbial growth risk. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting checklist. The PubMed, Web of Science, Medline, EMBASE, EBSCO, CNKI, CQVIP, and Wanfang Data databases were searched from 2010 to 2020 to identify eligible articles focused on methods of gastrointestinal endoscope drying and the status of endoscope drying. The following key points were analyzed: type of intervention, amount of residual droplets, major microbial types, and effectiveness of biofilm intervention. JBI quality assessment tool was used to determine bias risk for inclusion in the article. RESULTS: This review included twelve articles. Two of the articles reported lack of drying of gastrointestinal endoscopes while the other ten reported residual droplets, microbial growth, and biofilm formation after different methods of drying. Four articles reported 0 to 4.55 residual droplets; four articles reported that the main microbial types were cocci and bacilli, most commonly Staphylococcus, Escherichia coli, Bacillus maltophilia, and Pseudomonas aeruginosa; and two reported that drying could effectively reduce biofilm regeneration. The type of intervention is as follows: automatic endoscopy reprocessor (AER), manual compressed air drying, and the Dri-Scope Aid for automatic drying and drying cabinet. CONCLUSIONS: While endoscope reprocessing may not always be effective, an automatic endoscope reprocessor plus the Dri-Scope Aid with automatic drying over 10 min or storage in a drying cabinet for 72 h may be preferred.

Promoting DNA loading on magnetic nanoparticles using a DNA condensation strategy.

Maximizing DNA loading on magnetic nanoparticles (MNPs) is crucial for their successful utilization in gene transfer, DNA isolation, and bio-analytical applications. This enhancement is typically achieved by altering particle size and surfaces as well as charge density and ionic strength. We demonstrate a novel route for promoting DNA loading on amino-modified silica-coated magnetic nanoparticles (ASMNPs) by prior condensation of elongated DNA to a compact globule before adsorption. The enhanced DNA-loading capacity, as demonstrated by a reduction in the number of ASMNPs needed to achieve complexation, was presumably due to the elimination of DNA wrapping around nanoparticles and substantially reduced electrostatic interactions of DNA with nanoparticles because the compacted DNA globule conformation decreases its exposed surface charge. The maximum loading capacity of ASMNPs for condensed DNA was 4.4 times greater than that for elongated coiled DNA, achieving the highest ever reported value of 385 µg mg(-1). Practical applications for plasmid DNA isolation from cleared lysate confirmed the reliability of the proposed method.
