Application of indocyanine green-labeled fluorescence technology in laparoscopic total extra-peritoneal inguinal hernia repair surgery:a preliminary study.

BACKGROUND: Laparoscopic Total Extra-peritoneal Inguinal Hernia Repair(TEP) presents escalated risks of surgical complications, notably bleeding, particularly in European Hernia Society (EHS) types 3 and recurrent inguinal hernia. In this study, we introduced an innovative technique using indocyanine green-labeled fluorescence laparoscopy to mitigate intraoperative complications, including bleeding and rupture of the hernial sac. METHODS: This retrospective study reviewed records of 17 patients who underwent TEP repair at Anqing Municipal Hospital between July and August 2023. Intraoperatively, fluorescence imaging was utilized to trace the pathway of the spermatic vessels and outline the boundaries of the hernia sac to facilitate a thorough dissection. RESULTS: The procedure was successfully completed in all 17 patients, with a median operation time of 42 min (range: 30-51 min). Median intraoperative blood loss was 5 ml (range: 3-8 ml). Complete dissection of the hernia sac was achieved in each case without any incidents of sac rupture. Hemodynamic parameters of blood flow within the spermatic artery on postoperative day 1 showed no statistically significant deviations from the preoperative values. Furthermore, during the 7-month follow-up period, there were no cases of seroma formation or hernia recurrence. CONCLUSION: Our findings suggest that employing indocyanine green-labeled fluorescence technology in TEP repair significantly reduces intraoperative complications, notably bleeding and rupture of the hernial sac. This technique demonstrated a negligible impact on the hemodynamic parameters of the spermatic artery and reduced the overall surgical time.

Hematopoietic Stem Cell Transplantation for Acute Myeloid Leukemia: An Overview of Systematic Reviews.

Background: Hematopoietic stem cell transplantation (HSCT) has become the main treatment for acute myeloid leukemia (AML) and has been studied in many systematic reviews (SRs), but strong conclusions have not been drawn yet. Objective: This study aimed to summarize and critically evaluate the methodological and evidence quality of SRs and meta-analysis on this topic. Methods: PubMed, Embase, the Cochrane Library, and Web of Science were searched for SRs/meta-analyses regarding HSCT for AML. Two reviewers assessed the quality of SRs/meta-analyses in line with AMSTAR-2 and evaluated the strength of evidence quality with the grading of the evaluation system (GRADE) for concerned outcomes independently. Results: 12 SR/Meta articles were included, and the AMSTAR-2 scale showed that the quality grade of all articles was low or very low. GRADE results showed 29 outcomes, 2 of which were high, 12 were moderate, and 15 were low. Limitations and inconsistency were the most important factors leading to degradation, followed by imprecision and publication bias. Allo-SCT had better OS and DFS benefits than auto-SCT and significantly reduced the relapse in intermediate-risk AML/CR1 patients. Auto-SCT was associated with lower TRM than allo-SCT but generally had higher relapse. The results should be confirmed further for the low or moderate evidence quality. Conclusion: Current SRs show that allo-SCT in the treatment of AML might improve the OS, RFS, and DFS. Auto-SCT has significantly lower TRM but higher RR. Whether bone marrow transplantation is superior to nonmyeloablative chemotherapy remains to be evaluated. Meanwhile, the quality of methodology needs to be further improved. The intensity of evidence was uneven, and the high-quality evidence of outcomes was lacking. Considering the limitations of our overview, more rigorous and scientific studies are needed to fully explore the efficacy of different interventions of HSCT in AML, and clinicians should be more cautious in the treatment.

Low-dose apatinib and tegafur-gimeracil-oteracil as palliative treatment in recurrent cervical cancer patients with poor performance status: A case series.

WHAT IS KNOWN AND OBJECTIVE: A large proportion of recurrent cervical cancer (RCC) patients present with poor performance status (PS) after comprehensive treatments, which usually prevents them from opting for clinical trials. We retrospectively analysed the effect and safety of low-dose apatinib and tegafur-gimeracil-oteracil (TGO) in the treatment of these patients. CASE SUMMARY: Six patients treated with low-dose apatinib and TGO showed a disease control rate of 83.3% and grade 1-2 adverse events (AEs). WHAT IS NEW AND CONCLUSION: This case series indicates that low-dose apatinib and TGO could be considered as palliative therapy for RCC patients with poor PS.

[Risk factors for the complications of primary hypospadias urethroplasty with the urethral plate reserved].

OBJECTIVE: To investigate the risk factors for the complications of urethroplasty in patients with primary hypospadias by postoperative follow-up observation. METHODS: We retrospectively analyzed 110 cases of primary hypospadias repair performed from November 2010 to October 2015, including 70 cases of tubularized incised plate (TIP) urethroplasty and 40 cases of inlay internal preputial graft (IIPG) urethroplasty, all with the urethral plate reserved. We followed up the patients for 15.6－36 months, (27.3 ± 0.52) mo for those with and (26.9 ± 0.22) mo for those without complications. The mean age of the two groups of patients was (7.5 ± 0.2) and (7.0 ± 0.5) yr, respectively. RESULTS: The follow-up data were collected from all the patients, 17 (15.5%) with and 93 (84.5%) without complications. The success rate of surgery was 84.5%. There were no statistically significant differences in the follow-up time and age between the two groups of patients (P >0.05). Single-factor analysis of variance showed significant differences between the complication and non-complication groups in the preoperative urethral opening (P <0.01), ventral penile curvature (P <0.01), and length of urethral defect (P = 0.04), while multiple linear regression analysis exhibited that only ventral curvature was associated with the postoperative complications of the patients (OR = 1.12, 95% CI: 1.06－1.19, P<0.01). CONCLUSIONS: We chose single-stage urethroplasty with the urethral plate reserved for the treatment of primary hypospadias and achieved satisfactory outcomes. Ventral penile curvature is an independent risk factor for the complications of primary hypospadias, and a higher degree of curvature is associated with a higher incidnece of complications.

Levosimendan Versus Dobutamine in Myocardial Injury Patients with Septic Shock: A Randomized Controlled Trial.

BACKGROUND We aimed to investigate the effect of levosimendan on biomarkers of myocardial injury and systemic hemodynamics in patients with septic shock. MATERIAL AND METHODS After achieving normovolemia and a mean arterial pressure of at least 65 mmHg, 38 septic shock patients with low cardiac output (left ventricular ejective fraction), LEVF £45%) were randomly divided into two groups: levosimendan dobutamine. Patients in the levosimendan and dobutamine groups were maintained with intravenous infusion of levosimendan (0.2 µg/kg/minute) and dobutamine (5 µg/kg/minute) for 24 hours respectively. During treatment we monitored hemodynamics and LVEF, and measured levels of heart-type fatty acid binding protein (HFABP), troponin I (TNI), and brain natriuretic peptide(BNP). In addition, the length of mechanical ventilation, intensive care unit (ICU) stay, hospital stay, and 28-day mortality were compared between the two groups. RESULTS The levosimendan group and the dobutamine group were well matched with respect to age (years, 55.4 ± 1 7.5 versus 50.2 ± 13.6) and gender (males, 68.4% versus 57.9%). Levosimendan-treated patients had higher stroke volume index (SVI), cardiac index (CI), LVEF, and left ventricular stroke work index (LVSWI), and lower extravascular lung water index (EVLWI) compared to dobutamine-treated patients (p<0.05). HFABP, TNI, and BNP in the levosimendan group were less than in the dobutamine group (p<0.05). There was no difference in the mechanical ventilation time, length of stay in ICU and hospital, and 28-day mortality between the two groups. CONCLUSIONS Compared with dobutamine, levosimendan reduces biomarkers of myocardial injury and improves systemic hemodynamics in patients with septic shock. However, it does not reduce the days on mechanical ventilation, length of stay in ICU and hospital, or 28-day mortality.

[Roles of CXCR3 on lymphocytes and IP-10 of peripheral blood in infants with bronchiolitis].

OBJECTIVE: To study the roles of chemokine receptor 3 (CXCR3) on lymphocytes and interferon-γ-inducible protein-10 (IP-10) of peripheral blood in childhood bronchiolitis. METHODS: Fifty-five children with bronchiolitis were classified into Group I (with allergic factors) and Group II (without allergic factors). Twenty-eight children with noninfectious diseases were enrolled randomly as the control group. The expression of CXCR3 (CD183 as its molecular marker) on lymphocytes of peripheral blood was detected by flow cytometry. Serum IP-10 level was measured using ELISA. RESULTS: The expression of CD183(+) cells on CD4(+) and CD8(+) lymphocytes in peripheral blood in children with bronchiolitis from both Group I and Group II was significantly higher than that in the control group (P<0.05), and Group I had higher expression of CD183(+) cells on CD4(+) and CD8(+) lymphocytes than Group II (P<0.05).Serum IP-10 levels in Group I and Group II were significantly higher than those in the control group (P<0.05). However, there was no significant difference in serum IP-10 levels between Group I and Group II. CONCLUSIONS: CXCR3 and IP-10 are involved in the pathogenesis of bronchiolitis, and CXCR3 is associated with allergic factors.

[Down-regulatory effects of budesonide on expression of STAT6 and ORMDL3 in lung tissues of asthmatic mice].

OBJECTIVE: To investigate the roles of signal transduction and activator of transcription 6 (STAT6) and orosomucoid 1-like 3 (ORMDL3) in airway remodeling among asthmatic mice and to observe the effects of budesonide (BUD) on their expression. METHODS: Thirty BALB/c mice were randomly divided into control, asthma, and BUD intervention group. The mice were sensitized and challenged with ovalbumin (OVA) to establish a mouse model of asthma. The BUD intervention group received aerosol inhalation of BUD dissolved in normal saline 30 minutes before each OVA challenge, while normal saline was used instead of OVA solution in the control group. The pathological changes in the airway were observed by hematoxylin-eosin staining and Masson staining. The interleukin-13 (IL-13) level in lung homogenate was measured by enzyme-linked immunosorbent assay. The mRNA expression of STAT6 and ORMDL3 was measured by RT-PCR. RESULTS: The asthma group showed more pathological changes in the airway than the control and BUD intervention groups, and the BUD intervention group had reduced pathological changes in the airway compared with the asthma group. The asthma and BUD intervention groups had significantly higher IL-13 levels and mRNA expression of STAT6 and ORMDL3 than the control group (P<0.05), and these indices were significantly higher in the asthma group than in the BUD intervention group (P<0.05). The Pearson correlation analysis showed that STAT6 mRNA expression was positively correlated with ORMDL3 mRNA expression (r=0.676, P=0.032). CONCLUSIONS: STAT6 and ORMDL3 may be involved in the airway remodeling of mice, and BUD can reduce airway remodeling in asthmatic mice, possibly by down-regulating mRNA expression of STAT6 and ORMDL3.

DDIAS Regulation of STAT3/CCL2 Promotes Macrophage Polarization to M1 type in Kawasaki Disease.

OBJECTIVE: To investigate the molecular mechanism by which DNA damage induced apoptosis suppressor (DDIAS) regulates STAT3/CCL2 to enhance macrophage polarization to M1 type in Kawasaki disease (KD). METHODS: A KD vascular model was established by culturing human coronary artery endothelial cells (HCAECs) in vitro. Small interfering RNA of DDIAS (si-DDIAS) was transfected into the KD cell model. The human macrophage cell line THP-1 was induced into M1 macrophages using phorbol myristate acetate (PMA) and lipopolysaccharide (LPS) and co-cultured with the endothelial cells using the HCAECs medium. Western blot analysis was utilized to assess cellular DDIAS, p-STAT3, STAT3, and CCL2 protein expression. MTT was utilized to detect cell proliferation. ELISA was utilized to assess the expression levels of TNF-α, IL-4, IL-6, IL-8 and CCL2 in cell supernatants. Flow cytometry was utilized to examine cell apoptosis and the expression of M1 macrophage surface marker CD86. RESULTS: The expression level of DDIAS was elevated in the KD group compared to the Control group. Serum inhibition of HCAEC proliferation in the KD group was concentration-dependent and pro-inflammatory cytokines were substantially elevated, while the anti-inflammatory cytokines were substantially reduced (P<0.05). Compared to the si-NC group, cell proliferation was considerably enhanced; pro-inflammatory cytokines were substantially reduced; anti-inflammatory cytokines were substantially elevated, and the expression of p-STAT3 and CCL2 was lowered in the si-DDIAS group (P<0.05). The percentage of M1 macrophages was substantially elevated in the THP-1+LPS group compared to the THP-1 group (P<0.05). Compared to the THP-1+LPS+si-NC group, macrophage CCL2 expression was decreased in the THP-1+LPS+si-DDIAS group; the percentage of M1 macrophages was substantially lowered (P<0.05); and the levels of pro-inflammatory cytokines and CCL2 in the cell supernatant were substantially reduced. Incubation of macrophages with STAT3 agonist reversed these changes, which were exacerbated by the addition of neutralizing antibody CCL2. CONCLUSIONS: Downregulation of DDIAS inhibits macrophage polarization toward the M1 type through inhibition of the STAT3/CCL2 signaling pathway and can ameliorate vascular injury and inflammation in KD coronary arteries.

Several laboratory variables indicate severity and prognosis of COVID-19.

OBJECTIVE: While several laboratory variables have been used to assess COVID-19 disease, to our knowledge, no attempt has previously been made to compare differences across different patient groups. We attempted to evaluate the relationship between laboratory variables and severity of the disease as well as on prognosis. METHOD: We searched BioLINCC database and identified three studies which had separately included outpatients, inpatients, and ICU patients. For this re-analysis, we extracted data on general demography, laboratory variables and outcome. RESULT: In total, 2454 participants (496 outpatients [Study 1], 478 inpatients [Study 2], and 1480 ICU patients [Study 3]) were included in the analysis. We found three laboratory variables (i.e., creatinine, aspartate transferase, and albumin) were not only prognostic factors for outcome of inpatients with COVID-19, but also reflected disease severity as they were significantly different between inpatients and ICU patients. These three laboratory variables are an indication of kidney function, liver function, and nutritional status. CONCLUSION: For patients with COVID-19, in addition to monitoring infectious disease indicators, we need to pay attention to liver function, renal function, and take timely measures to correct them to improve prognosis.

Reporting quality of meta-analyses in acupuncture: Investigating adherence to the PRISMA statement.

Although Systematic Reviews and Meta-Analyses (PRISMA) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Acupuncture (PRISMA-A) checklists had been in use for several years, compliance rate was still not optimistic. We investigated the quality of reporting for meta-analyses of acupuncture published in PubMed. We compared the compliance rate for the quality of reporting following the publication of both the PRISMA and PRISMA-A recommendations. We searched PubMed for articles published between January 1st, 2020 and December 31st, 2022, after Endnote X9 document management software and manual screening, 180 meta-analyses of acupuncture were selected as samples. The PRISMA, and PRISMA-A checklists were used to evaluate the quality of the literature. Data were collected using a standard form. Pearson χ2 test and/or Fisher exact test were used to assess differences in reporting among groups. Logistic regression is used to calculate OR and its 95% CI. The total reported compliance rate of all items in the PRISMA list was 61.3%, and the reported compliance rate of the items with a compliance rate of <50% accounted for 35.71% of the total items. The total reported coincidence rate of all items in the PRISMA-A was 56.9%, and the reported coincidence rate of the items with a reported coincidence rate of <50% accounted for 31.25% of all the items. The compliance rate of the published research to PRISMA or PRISMA-A has no statistical difference between the Journal Citation Reports partition (Quarter1-Quarter2) and Journal Citation Reports partition (Quarter3-Qurater4) (P > .05). Regardless of the level of journals published, have obvious deficiencies in the details of the study, the reference basis for the design of the study, the analysis method, the degree of strictness, the scientific nature, and other aspects. We must strengthen education on the standardization of research reports.

Misdiagnosed Meckel's diverticulum with internal hernia mimicking appendicitis: A case report.

BACKGROUND: Meckel's diverticulum is a common congenital anomaly of the gastrointestinal tract, with a higher incidence rate in children under 7 years old. The condition is characteristically asymptomatic but may become a clinical concern when complications such as intestinal obstruction, bleeding, perforation, or diverticulitis precipitate acute abdominal presentations. CASE SUMMARY: This report describes the case of a middle-aged man initially suspected of having acute appendicitis, which rapidly progressed to acute peritonitis with concomitant intestinal obstruction observed during preoperative assessment. Surgical exploration confirmed the diagnosis of Meckel's diverticulum-induced internal hernia, accompanied by intestinal obstruction and necrosis. In addition, the hernial ring base exhibited entrapment resembling a surgical knot. CONCLUSION: Meckel's diverticulum is a rare cause of small bowel obstruction in adults, and it should be considered in a differential diagnosis.

A meta-analysis for the diagnostic accuracy of SelectMDx in prostate cancer.

To overview the diagnostic accuracy of SelectMDx for the detection of clinically significant prostate cancer and to review sources of methodologic variability. Four electronic databases, including PubMed, Embase, Web of Science, and Cochrane Library were searched for eligible studies investigating the diagnostic value of SelectMDx compared with the gold standard. The pooled sensitivity, specificity, and positive and negative predictive values were calculated. Included studies were assessed according to the Standards for Quality Assessment of Diagnostic Accuracy Studies 2 tool. The review identified 14 relevant publications with 2579 patients. All reports constituted phase 1 biomarker studies. Pooled analysis of findings found an area under the receiver operating characteristic analysis curve of 70% [95% CI, 66%-74%], a sensitivity of 81% [95% CI, 69%-89%], and a specificity of 52% [95% CI, 41%-63%]. The positive likelihood ratio was 1.68, and the negative predictive value is 0.37. Factors that may influence variability in test results included the breath collection method, the patient's physiologic condition, the test environment, and the method of analysis. Considerable heterogeneity was observed among the studies owing to the difference in the sample size. SelectMDx appears to have moderate to good diagnostic accuracy in differentiating patients with clinically significant prostate cancer from people at high risk of developing prostate cancer. Higher-quality clinical studies assessing the diagnostic accuracy of SelectMDx for clinically significant cancer are still needed.

Performance of artificial intelligence in predicting the prognossis of severe COVID-19: a systematic review and meta-analysis.

Background: COVID-19-induced pneumonia has become a persistent health concern, with severe cases posing a significant threat to patient lives. However, the potential of artificial intelligence (AI) in assisting physicians in predicting the prognosis of severe COVID-19 patients remains unclear. Methods: To obtain relevant studies, two researchers conducted a comprehensive search of the PubMed, Web of Science, and Embase databases, including all studies published up to October 31, 2023, that utilized AI to predict mortality rates in severe COVID-19 patients. The PROBAST 2019 tool was employed to assess the potential bias in the included studies, and Stata 16 was used for meta-analysis, publication bias assessment, and sensitivity analysis. Results: A total of 19 studies, comprising 26 models, were included in the analysis. Among them, the models that incorporated both clinical and radiological data demonstrated the highest performance. These models achieved an overall sensitivity of 0.81 (0.64-0.91), specificity of 0.77 (0.71-0.82), and an overall area under the curve (AUC) of 0.88 (0.85-0.90). Subgroup analysis revealed notable findings. Studies conducted in developed countries exhibited significantly higher predictive specificity for both radiological and combined models (p < 0.05). Additionally, investigations involving non-intensive care unit patients demonstrated significantly greater predictive specificity (p < 0.001). Conclusion: The current evidence suggests that artificial intelligence prediction models show promising performance in predicting the prognosis of severe COVID-19 patients. However, due to variations in the suitability of different models for specific populations, it is not yet certain whether they can be fully applied in clinical practice. There is still room for improvement in their predictive capabilities, and future research and development efforts are needed.

Interaction of Cecropin A (1-7) Analogs with DNA Analyzed by Multi-spectroscopic Methods.

Cecropin A (1-7) is a cationic antimicrobial peptide which contain lots of basic amino acids. To understand the effect of basic amino acids on cecropin A (1-7), analogues CA2, CA3 and CA4 which have more arginine or lysine at the N-terminal or C-terminal were designed and synthesized. The interaction of cecropin A (1-7) and its analogs with DNA was studied using ultraviolet-visible spectroscopy, fluorescence spectroscopy and circular dichroism spectroscopy. Multispectral analysis showed that basic amino acids improved the interaction between the analogues and DNA. The interaction between CA4 and DNA is most pronounced. Fluorescence spectrum indicated that Ksv value of CA4 is 1.19 × 105  L mol-1 compared to original peptide cecropin A (1-7) of 3.73 × 104  L mol-1. The results of antimicrobial experiments with cecropin A (1-7) and its analogues showed that basic amino acids enhanced the antimicrobial effect of the analogues. The antimicrobial activity of CA4 against E. coli was eightfold higher than that of cecropin A (1-7). The importance of basic amino acid in peptides is revealed and provides useful information for subsequent studies of antimicrobial peptides.

3D printing calcium phosphate ceramics with high osteoinductivity through pore architecture optimization.

The osteoinductivity of 3D printed calcium phosphate (CaP) ceramics has a large gap compared with those prepared by conventional foaming methods, and improving the osteoinductivity of 3D printing CaP ceramics is crucial for successful application in bone regeneration. Pore architecture plays a critical role in osteoinductivity. In this study, CaP ceramics with a hexagonal close-packed (HCP) spherical pore structure were successfully fabricated using DLP printing technology. Additionally, octahedral (Octahedral), diamond (Diamond), and helical (Gyroid) structures were constructed with similar porosity and macropore diameter. CaP ceramics with the HCP structure exhibited higher compression strength (8.39 ± 1.82 MPa) and lower permeability (6.41 × 10-11 m2) compared to the Octahedral, Diamond, and Gyroid structures. In vitro cellular responses indicated that the macropore architecture strongly influenced the local growth rate of osteoblast-formed cell tissue; cells grew uniformly and formed circular rings in the HCP group. Furthermore, the HCP group promoted the expression of osteogenic genes and proteins more effectively than the other three groups. The outstanding osteoinductivity of the HCP group was confirmed in canine intramuscular implantation studies, where the new bone area reached up to 8.02 ± 1.94 % after a 10-week implantation. Additionally, the HCP group showed effective bone regeneration in repairing femoral condyle defects. Therefore, our findings suggest that 3D printed CaP bioceramics with an HCP structure promote osteoinductivity and can be considered as candidates for personalized precise treatment of bone defects in clinical applications. STATEMENT OF SIGNIFICANCE: 1. 3D printing BCP ceramics with high osteoinductivity were constructed through pore architecture optimization. 2. BCP ceramics with HCP structure exhibited relatively higher mechanical strength and lower permeability than those with Octahedral, Diamond and Gyroid structures. 3. BCP ceramics with HCP structure could promote the osteogenic differentiation of MC3T3-E1, and showed the superior in-vivo osteoinductivity and bone regeneration comparing with the other structures.

An activatable NIR turn-on fluorescent probe for copper (II) ion and live cell imaging.

Herein we have reported a fluorescent probe (MB-M) based on MB derivative for Cu2+ ions detection. The probe was well characterized by 1H NMR, 13C NMR and HR-MS spectrum. Probe MB-M showed naked-eyes recognition to Cu2+ as color change from colorless to indigo. The probe exhibited promising features such as high fluorescence and UV-vis selectivity, fast response (5 mint), workable at pH 2-7, and low limit of detection (LOD = 0.33 µM). Probe MB-M was also used for Cu2+ ions imaging in HepG-2 cells and detection in daily life (Test Strip and lake water). Moreover, non-covalent interaction (NCI) and quantum theory of atoms in molecules (QTAIM) analysis were used to study the interaction between MB-M and Cu2+ ions. By examining the electronic characteristics of the complex using natural bond orbital (NBO), electron density difference (EDD), and frontier molecular orbital (FMO) analysis, the sensitivity of MB-M towards Cu2+ ions were investigated. The results illustrated that the interactions between MB-M and Cu2+ ions involved chemisorption.

Quantifying chemical correlations between fruits and processed fruit products: A non-targeted analysis approach.

Juices and beverages are produced by industry for long-distance distribution and shelf-stability, providing valuable nutrients. However, their nutritional value is often underestimated due to insufficient analytical methods. We have employed non-targeted analysis through a standardized analytical protocol, taking advantage of Data Independent Acquisition (DIA) technique and a novel Chromatographic Retention Behavior (CRB) data deconvolution algorithm. After analyzing 9 fruits and their products, correlations between fruits and their juices are accurately digitalized by similarities of their LC-MS fingerprints. We also specify non-targeted molecules primarily associate with nutrient loss in these analyzed juice products, including nitrogenous nutrients, flavonoids, glycosides, and vitamins. Moreover, we unveiled previously unreported fruit-characteristic metabolites, of which reconstituted-from-concentrate (RFC) juices contain over 40% of the content found in their fresh counterparts. Conclusively, our method establishes a quantitative benchmark for rational selection of RFC juices to substitute natural fruits.

Early diagnosis for pulmonary embolism: A systematic review and meta-analysis.

BACKGROUND: The incidence of acute pulmonary embolism (APE) (especially early diagnosis) has increased annually in recent years, but the diagnosis of APE is a great challenge for every clinician. However, few studies have evaluated multiple diagnostic indicators simultaneously. METHODS: A systematic search was performed using CNKI, Wan fang data, VIP, PubMed and Web of Science for studies on the diagnosis of pulmonary embolism published up to October 31, 2022. Using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2), we evaluated the risk of bias in included studies, and used a random-effects meta-analysis to obtain the summary sensitivity and specificity. The data that were extracted and calculated for this study included the first author, year of publication, country, study type, sample size, disease type, gold standard, diagnostic indicators and 4-compartment table data. We strictly followed the Preferred Reporting Items for Systematics reviews and Meta-Analysis (PRISMA) guidelines in this review. RESULTS: This study included 30 articles with a total sample size of 8947 cases, involving 4 detection methods: D-dimer, Geneva rules, Wells rules, and lung imaging. The combined effect size showed that lung imaging had the highest diagnostic value (SEN = 0.95, SPE = 0.89), followed by D-dimer (SEN = 0.92, SPE = 0.60), Geneva rules (SEN = 0.78, SPE = 0.68), and Wells rules (SEN = 0.77, SPE = 0.67). The area of lung imaging was largest under the Summary Receiver Operator Characteristic (SROC) curve (AUC = 0.97), followed by Geneva rules (AUC = 0.80), Wells rules (AUC = 0.79), and D-dimer (AUC = 0.74). CONCLUSION: All 4 detection methods showed good ability to diagnose PE, and lung imaging was the best. Clinical trials are recommended to build an early decision-making model for the diagnosis of pulmonary embolism in order to increase the detection rate and improve prognosis.

Biomimetic urine flow control can preserve bladder function in patients with indwelling catheterization.

For patients with long-term indwelling catheterization, bladder function will be affected. It is necessary to explore whether biomimetic urine flow control (BUFC) can improve bladder function in patients undergoing indwelling catheterization. A retrospective, data-only, cohort study was carried out. The patients admitted to the intensive care unit, who had retained catheter and been continuously using a urodynamic monitoring system for over 30 days were selected. They were divided into 2 groups based on whether they were using BUFC function. The urodynamic monitoring data of the 2 groups were compared and analyzed. A total of 30 patients were included in the final analysis, including 15 in the BUFC group and 15 in the unobstructed group. The Urinary Volume and maximal urinary flow rate of the unobstructed group showed a continuous downward trend, while the BUFC group remained stable, and there was a statistical difference (P < .05) between the 2 groups since day 20. The bladder ultrasound imaging showed that the bladder volume of the BUFC group did not decrease significantly on the 30th day. BUFC technology, which provided by a urodynamic monitoring system, has potential protective effects of the bladder function after indwelling catheterization.
