Comparison of the value of the GI-RADS and ADNEX models in the diagnosis of adnexal tumors by junior physicians.

Objective: To compare the diagnostic effectiveness of the Gynecologic Imaging Reporting and Data System (GI-RADS) and Neoplasias in the Adnexa (ADNEX) model for the diagnosis of benign and malignant ovarian tumors by junior physicians. Methods: The sonographic data of 634 patients with ovarian tumors confirmed by pathology in our hospital over 4 years were analyzed retrospectively by junior doctors. The diagnostic efficacy of the GI-RADS and ADNEX models was compared based on pathology. Results: (1) Regarding the diagnostic efficacy of the GI-RADS and ADNEX models, the sensitivity was 90.15% and 84.85%, the specificity was 87.65% and 85.86%, the accuracy rates were 88.17% and 85.65%, and the Youden Indices were 0.778 and 0.707, respectively. The areas under the receiver operating characteristic (ROC) curves were 0.924 (95% CI: 0.900-0.943) and 0.933 (95% CI: 0.911-0.951), respectively. The GI-RADS classification was equivalent to that of the ADNEX model in the diagnosis of adnexal tumors (P>0.05). These findings were highly consistent with the pathological results (Kappa values were 0.684 and 0.691, respectively). (2) When differentiating between different pathological types of adnexal tumors, the ADNEX model had the best diagnostic value for distinguishing between benign tumors and stage II-IV ovarian cancer (AUC=0.990, 95% CI: 0.978-0.997). Conclusions: (1) The diagnostic efficacy of the GI-RADS and ADNEX models in the diagnosis of benign and malignant ovarian tumors by junior physicians is excellent and comparable. (2) The ADNEX model shows good value for differentiating ovarian tumors of different pathological types by junior physicians.

Ultrasound Diagnosis of Bilateral Primary Breast Burkitt Lymphoma in a 28-Year-Old Lactating Patient: A Case Report.

Primary breast Burkitt lymphoma (PB-BL) is an exceedingly rare form of primary breast lymphoma. Ultrasonography is the preferred modality for diagnosing breast diseases; however, the ultrasonic features of Burkitt lymphoma have rarely been reported. Herein, we report a case of ultrasonically diagnosed bilateral PB-BL in a lactating patient and present a literature review. A 28-year-old female patient experienced bilateral breast engorgement starting more than a month after childbirth. At three months postpartum, the patient experienced extreme bilateral breast engorgement, with the skin appearing dark purple and jaundiced. Based on the imaging diagnosis, pathological, immunohistochemical, and molecular biological findings, she was diagnosed with Burkitt lymphoma involves bilateral breasts, right adrenal glands, uterus, and multiple bones. After 4 cycles of combination chemotherapy, the tumor basically disappeared, and then after autologous stem cell transplantation and one cycle of combination chemotherapy, the patient is generally in good condition and is under follow-up. We found that the ultrasonic characteristics of PB-BL are different from those of common breast cancer or lactation mastitis. PB-BL lesions are often multiple, large masses, and even involve the whole breast. The characteristic reticular structures are common in lesions, and irregular hyperechoic masses can be seen around it. The mass has abundant peripheral and internal blood flow signals, but internal calcification and attenuated posterior echoes of masses are rarely observed. Thus, the ultrasonic features of breast Burkitt lymphoma are somewhat specific and understanding these features is conducive to its early identification.

Evaluating fetal lung development at various gestational weeks using two-dimensional shear wave elastography.

Background: Noninvasive evaluation of fetal lung development is a critical area of study. Two-dimensional shear-wave elastography (2D-SWE) provides valuable insights into tissue stiffness, potentially correlating with different stages of lung development. This study aims to explore the potential of the 2D-SWE technique for assessing the maturity of fetal lung development. Methods: This prospective cohort study included pregnant women undergoing routine antenatal ultrasound examinations at the Second Affiliated Hospital of Fujian Medical University and Quanzhou Women's and Children's Hospital from September 2022 to September 2023. The study consecutively recruited 300 pregnant women with normal pregnancies and 15 who opted for induced labor. Among those with normal pregnancies, the study assessed the differences in fetal pulmonary and hepatic elasticity measurements across different gestational weeks (GW) using one-way analysis of variance (ANOVA). Furthermore, regression analyses using linear, quadratic, and cubic equations were conducted to investigate the relationship between fetal parameters and GW. For those who opted for induced labor, elasticity measurements were taken before induction, and fetal lung tissue specimens were collected for post-induction observation. Results: Fetal lung and liver elasticity values, along with the lung-to-liver elasticity ratio (LLE ratio), showed significant variations across different GW (P<0.05). Specifically, fetal lung elasticity values initially increased and then decreased as GW advanced (R2=0.41). Liver elasticity values continuously increased throughout GW, though the rate of increase diminished during the prenatal period (R2=0.37). The LLE ratio values increased and then decreased over GW, fluctuating overall between 0.8 and 0.9 (R2=0.14). A 71.4% concordance was observed between the predicted stage of lung development, based on lung elasticity values, and the histological stage of lung development in the induced fetuses. Conclusions: 2D-SWE can depict the maturation of fetal lung development at various stages.

The establishment and severity assessment of ultrasound-guided prenatal bronchopulmonary dysplasia model in rat.

To study a new method for establishing animal models of prenatal bronchopulmonary dysplasia (BPD), we used lung ultrasound score (LUS) to semi-quantitatively assess the severity of lung lesions in model rats. Lipopolysaccharide (LPS) was injected into the right lung of the fetus of the rat under ultrasound-guided, and the right lung of the neonates were scanning for LUS. Specimens were collected for pathological scoring and detection of pulmonary surfactant-associated glycoprotein (SP)-C and vascular endothelial growth factor (VEGF) expression quantity. The correlation between LUS and pathological scores was analyzed. (1) The animal models were consistent with the pathological manifestations of BPD. (2) It showed a strong positive correlation between LUS and pathological scores in animal models (r = 0.84, P < 0.005), and the expression quantity of SP-C and VEGF in lung tissue were decreased (both P < 0.05). Animal models established by ultrasound-guided puncture of the lung of rats and injection of LPS were consistent with the manifestation of BPD. This method could be used to establish animal models of BPD before birth, and the severity of BPD could be assessed by using LUS.

Developing a deep learning model for predicting ovarian cancer in Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS US) Category 4 lesions: A multicenter study.

PURPOSE: To develop a deep learning (DL) model for differentiating between benign and malignant ovarian tumors of Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS US) Category 4 lesions, and validate its diagnostic performance. METHODS: A retrospective analysis of 1619 US images obtained from three centers from December 2014 to March 2023. DeepLabV3 and YOLOv8 were jointly used to segment, classify, and detect ovarian tumors. Precision and recall and area under the receiver operating characteristic curve (AUC) were employed to assess the model performance. RESULTS: A total of 519 patients (including 269 benign and 250 malignant masses) were enrolled in the study. The number of women included in the training, validation, and test cohorts was 426, 46, and 47, respectively. The detection models exhibited an average precision of 98.68% (95% CI: 0.95-0.99) for benign masses and 96.23% (95% CI: 0.92-0.98) for malignant masses. Moreover, in the training set, the AUC was 0.96 (95% CI: 0.94-0.97), whereas in the validation set, the AUC was 0.93(95% CI: 0.89-0.94) and 0.95 (95% CI: 0.91-0.96) in the test set. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive values for the training set were 0.943,0.957,0.951,0.966, and 0.936, respectively, whereas those for the validation set were 0.905,0.935, 0.935,0.919, and 0.931, respectively. In addition, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for the test set were 0.925, 0.955, 0.941, 0.956, and 0.927, respectively. CONCLUSION: The constructed DL model exhibited high diagnostic performance in distinguishing benign and malignant ovarian tumors in O-RADS US category 4 lesions.

Porta hepatis lymph nodes on US: not only identify biliary atresia but also predict outcomes after Kasai portoenterostomy surgery.

OBJECTIVES: To evaluate the usefulness of porta hepatis lymph nodes (PHLNs) on ultrasonography (US) scans in diagnosing biliary atresia (BA) and predicting the outcomes after Kasai portoenterostomy (KPE) surgery. METHODS: A total of 668 patients from one hospital were enrolled in the study (542 non-BA and 126 BA). The independent and combined diagnostic efficacy of PHLNs, triangular cord (TC) thickness, and gallbladder morphology were assessed by drawing the receiver operating characteristic (ROC) curves and counting the area under the ROC curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The US features, histopathological findings of PHLNs, and serum total bilirubin (TBIL) levels 3 months post-KPE were correlated. RESULTS: The AUC, sensitivity, specificity, PPV, and NPV of PHLNs with hyperechogenicity and a maximum length larger than 8.4 mm were 0.898, 81.8%, 97.8%, 89.6%, and 95.8%, respectively. The combination of PHLNs, TC thickness, and gallbladder morphology achieved the best overall diagnostic efficacy among all indicators with an AUC of 0.927 and a sensitivity of 99.2%. The germinal center number and bile particle number of PHLNs were positively correlated with pathological size and US echogenicity intensity of PHLNs, respectively (r = 0.591, 0.377, p = 0.001, 0.004). The pathological size of PHLNs in BA patients was negatively correlated with jaundice clearance status 3 months after KPE surgery (r = -0.385, p = 0.047). CONCLUSION: PHLNs with hyperechogenicity and a maximum length > 8.4 mm are useful US indicators for BA diagnosis. Additionally, the enlargement of PHLNs might play a role in predicting outcomes of KPE surgery. CRITICAL RELEVANCE STATEMENT: The article proposed for the first time that PHLNs with hyperechogenicity and a maximum length > 8.4 mm are a useful US indicator for diagnosing BA. KEY POINTS: PHLNs may be helpful in diagnosing BA and predicting outcomes after surgery. Enlarged hyperechoic PHLNs are a useful diagnostic indicator for BA, and play a role in predicting surgical outcomes. These findings can assist clinicians in more accurately diagnosing BA, enabling more timely treatments.

A novel simplified transperineal prostate biopsy guided by perineal ultrasound.

BACKGROUND: Prostate biopsies are mainly performed through transrectal or perineal approaches, while ultrasound probes are located in the rectum for guidance. However, reports on the use of perineal ultrasound-guided transperineal prostate biopsy (PG-TPPB) are few. METHODS: A retrospective case-control study was designed. A total of 111 patients who underwent PG-TPPB from February 2019 to December 2020 were investigated retrospectively. Simultaneously, 188 patients who underwent transrectal prostate biopsy (TRPB) were included as control. The prostate cancer detection rates (PCDR), complication rates, and application values were compared between the 2 groups. RESULTS: The overall PCDR in the PG-TPPB and TRPB groups were 33.3% (37/111) and 39.9% (75/188), respectively (P = .258). There was no significant difference in the PCDR between the 2 groups under each prostate-specific antigen level (all P > .05). The single-needle PCDR in the PG-TPPB and TRPB groups were 21.5% (277/1 287) and 24.0% (513/2 134), respectively (P = .091). The incidence of complications in the PG-TPPB group was significantly lower than that in the TRPB group (8.1% vs 21.3%, P = .003). CONCLUSIONS: The PCDRs of PG-TPPB and TRPB were the same. However, the postoperative complication rate of PG-TPPB was significantly lower than that of TRPB. Moreover, PG-TPPB required simpler equipment and did not require enema administration, which is suitable for patients with rectal contraindications. ADVANCES IN KNOWLEDGE: The reports on PG-TPPB are few. Our study indicated that PG-TPPB reduced the postoperative complication rate. Moreover, PG-TPPB required simpler equipment. Importantly, PG-TPPB is suitable for patients with rectal contraindications.

Multimodal ultrasound imaging: a method to improve the accuracy of sentinel lymph node diagnosis in breast cancer.

Aim: This study assessed the utility of multimodal ultrasound in enhancing the accuracy of breast cancer sentinel lymph node (SLN) assessment and compared it with single-modality ultrasound. Methods: Preoperative examinations, including two-dimensional ultrasound (2D US), intradermal contrast-enhanced ultrasound (CEUS), intravenous CEUS, shear-wave elastography (SWE), and surface localization, were conducted on 86 SLNs from breast cancer patients. The diagnostic performance of single and multimodal approaches for detecting metastatic SLNs was compared to postoperative pathological results. Results: Among the 86 SLNs, 29 were pathologically diagnosed as metastatic, and 57 as non-metastatic. Single-modality ultrasounds had AUC values of 0.826 (intradermal CEUS), 0.705 (intravenous CEUS), 0.678 (2D US), and 0.677 (SWE), respectively. Intradermal CEUS significantly outperformed the other methods (p<0.05), while the remaining three methods had no statistically significant differences (p>0.05). Multimodal ultrasound, combining intradermal CEUS, intravenous CEUS, 2D US, and SWE, achieved an AUC of 0.893, with 86.21% sensitivity and 84.21% specificity. The DeLong test confirmed that multimodal ultrasound was significantly better than the four single-modal ultrasound methods (p<0.05). Decision curve analysis and clinical impact curves demonstrated the superior performance of multimodal ultrasound in identifying high-risk SLN patients. Conclusion: Multimodal ultrasound improves breast cancer SLN identification and diagnostic accuracy.

Advances in artificial intelligence for the diagnosis and treatment of ovarian cancer (Review).

Artificial intelligence (AI) has emerged as a crucial technique for extracting high­throughput information from various sources, including medical images, pathological images, and genomics, transcriptomics, proteomics and metabolomics data. AI has been widely used in the field of diagnosis, for the differentiation of benign and malignant ovarian cancer (OC), and for prognostic assessment, with favorable results. Notably, AI­based radiomics has proven to be a non­invasive, convenient and economical approach, making it an essential asset in a gynecological setting. The present study reviews the application of AI in the diagnosis, differentiation and prognostic assessment of OC. It is suggested that AI­based multi­omics studies have the potential to improve the diagnostic and prognostic predictive ability in patients with OC, thereby facilitating the realization of precision medicine.

The application value of lung ultrasound scoring in assessing disease severity: Evaluation of small-scale outbreaks of COVID-19.

PURPOSE: This study explored the use of transthoracic lung ultrasound for evaluating COVID-19 patients, compared it with computed tomography (CT), and examined its effectiveness using 8 and 12 lung regions. METHODS: A total of 100 patients with COVID-19 and 40 healthy volunteers were assessed using 12 regions (bilateral upper/lower regions of the anterior/lateral/posterior chest) and simplified 8 zones (bilateral upper/lower regions of the anterior/lateral chest) transthoracic lung ultrasound. The relationships between ultrasound, CT, and clinical indicators were analyzed to evaluate the diagnostic value of ultrasound scores in COVID-19. RESULTS: Increased disease severity correlated with increased 8- and 12-zone ultrasound and CT scores (all p < 0.05). The modified 8-zone method strongly correlated with the 12-zone method (Pearson's r = 0.908, p < 0.05). The 8- and 12-zone methods correlated with CT scoring (correlation = 0.568 and 0.635, respectively; p < 0.05). The intragroup correlation coefficients of the 8-zone, 12-zone, and CT scoring methods were highly consistent (intragroup correlation coefficient = 0.718, p < 0.01). The 8-zone ultrasound score correlated negatively with oxygen saturation (rs = 0.306, p < 0.05) and Ca (rs = 0.224, p < 0.05) and positively with IL-6 (rs = 0.0.335, p < 0.05), erythrocyte sedimentation rate (rs = 0.327, p < 0.05), alanine aminotransferase (rs = 0.230, p < 0.05), and aspartate aminotransferase (rs = 0.251, p < 0.05). The 12-zone scoring method correlated negatively with oxygen saturation (rs = 0.338, p < 0.05) and Ca (rs = 0.245, p < 0.05) and positively with IL-6 (rs = 0.354, p < 0.05) and erythrocyte sedimentation rate (rs = 0.495, p < 0.05). CONCLUSION: Lung ultrasound scores represent the clinical severity and have high clinical value for diagnosing COVID-19 pneumonia. The 8-zone scoring method can improve examination efficiency and reduce secondary injuries caused by patient movement.

Latest progress in low-intensity pulsed ultrasound for studying exosomes derived from stem/progenitor cells.

Stem cells have self-renewal, replication, and multidirectional differentiation potential, while progenitor cells are undifferentiated, pluripotent or specialized stem cells. Stem/progenitor cells secrete various factors, such as cytokines, exosomes, non-coding RNAs, and proteins, and have a wide range of applications in regenerative medicine. However, therapies based on stem cells and their secreted exosomes present limitations, such as insufficient source materials, mature differentiation, and low transplantation success rates, and methods addressing these problems are urgently required. Ultrasound is gaining increasing attention as an emerging technology. Low-intensity pulsed ultrasound (LIPUS) has mechanical, thermal, and cavitation effects and produces vibrational stimuli that can lead to a series of biochemical changes in organs, tissues, and cells, such as the release of extracellular bodies, cytokines, and other signals. These changes can alter the cellular microenvironment and affect biological behaviors, such as cell differentiation and proliferation. Here, we discuss the effects of LIPUS on the biological functions of stem/progenitor cells, exosomes, and non-coding RNAs, alterations involved in related pathways, various emerging applications, and future perspectives. We review the roles and mechanisms of LIPUS in stem/progenitor cells and exosomes with the aim of providing a deeper understanding of LIPUS and promoting research and development in this field.

Risk estimation for postoperative nausea and vomiting: development and validation of a nomogram based on point-of-care gastric ultrasound.

BACKGROUND: We aimed to develop a nomogram that can be combined with point-of-care gastric ultrasound and utilised to predict postoperative nausea and vomiting (PONV) in adult patients after emergency surgery. METHODS: Imaging and clinical data of 236 adult patients undergoing emergency surgery in a university hospital between April 2022 and February 2023 were prospectively collected. Patients were divided into a training cohort (n = 177) and a verification cohort (n = 59) in a ratio of 3:1, according to a random number table. After univariate analysis and multivariate logistic regression analysis of the training cohort, independent risk factors for PONV were screened to develop the nomogram model. The receiver operating characteristic curve, calibration curve, decision curve analysis (DCA) and clinical impact curve (CIC) were used to evaluate the prediction efficiency, accuracy, and clinical practicability of the model. RESULTS: Univariate analysis and multivariate logistic regression analysis showed that female sex, history of PONV, history of migraine and gastric cross-sectional area were independent risk factors for PONV. These four independent risk factors were utilised to construct the nomogram model, which achieved significant concordance indices of 0.832 (95% confidence interval [CI], 0.771-0.893) and 0.827 (95% CI, 0.722-0.932) for predicting PONV in the training and validation cohorts, respectively. The nomogram also had well-fitted calibration curves. DCA and CIC indicated that the nomogram had great clinical practicability. CONCLUSIONS: This study demonstrated the prediction efficacy, differentiation, and clinical practicability of a nomogram for predicting PONV. This nomogram may serve as an intuitive and visual guide for rapid risk assessment in patients with PONV before emergency surgery.

A nomogram for predicting the risk of intra-abdominal hypertension in critically ill patients based on ultrasound and clinical data.

Background: Intra-abdominal hypertension (IAH) is a common complication in critically ill patients. This study aimed to identify independent risk factors for IAH and generate a nomogram to distinguish IAH from non-IAH in these patients. Methods: We retrospectively analyzed 89 critically ill patients and divided them into an IAH group [intra-abdominal pressure (IAP) ≥12 mmHg] and a non-IAH group (IAP <12 mmHg) based on the IAP measured from their bladders. Ultrasound and clinical data were also measured. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for IAH. The correlation between IAP and independent risk factors was also assessed. Results: Of these 89 patients, 45 (51%) were diagnosed with IAH. Univariate analysis showed there were significant differences in the right renal resistance index (RRRI) of the interlobar artery, the right diaphragm thickening rate (RDTR), and lactic acid (Lac) between IAH and non-IAH groups (P<0.001). Multivariate logistic regression analysis revealed that increasing RRRI, RDTR, and Lactic acid (Lac) were independent risk factors for IAH (P=0.001, P=0.001, and P=0.039, respectively). IAP was significantly correlated with RRRI, RDTR, and Lac (r=0.741, r=-0.774, and r=0.396, respectively; P<0.001). The prediction model based on regression analysis results was expressed as follows: predictive score = -17.274 + 31.125 × RRRI - 29.074 × RDTR + 0.621 × Lac. Meanwhile, the IAH nomogram prediction model was established with an area under the receiver operating characteristic (ROC) curve of 0.956 (95% confidence interval: 0.909-1.000). The nomogram showed good calibration for IAH with the Hosmer-Lemeshow test (P=0.864) and was found to be applicable within a wide threshold probability range, especially that higher than 0.40. Conclusions: The noninvasive nomogram based on ultrasound and clinical data has good diagnostic efficiency and can predict the risk of IAH. This nomogram may provide valuable guidance for clinical interventions to reduce IAH morbidity and mortality in critically ill patients.

Can the ultrasound microcystic pattern accurately predict borderline ovarian tumors?

OBJECTIVE: To investigate whether the ultrasound microcystic pattern (MCP) can accurately predict borderline ovarian tumors (BOTs). METHODS: A retrospective collection of 393 patients who met the inclusion criteria was used as the study population. Indicators that could well identify BOT in different pathological types of tumors were derived by multivariate unordered logistic regression analysis. Finally, the correlation between ultrasound MCP and pathological features was analyzed. RESULTS: (1) MCP was present in 55 of 393 ovarian tumors, including 34 BOTs (34/68, 50.0%), 16 malignant tumors (16/88, 18.2%), and 5 benign tumors (5/237, 2.1%). (2) Univariate screening showed significant differences (P < 0.05) in patient age, CA-125 level, ascites, > 10 cyst locules, a solid component, blood flow, and MCP among BOTs, benign ovarian tumors, and malignant ovarian tumors. (3) Multivariate unordered logistic regression analysis showed that the blood flow, > 10 cyst locules, and MCP were significant factors in identifying BOTs (P < 0.05). (4) The pathology of ovarian tumors with MCP showed "bubble"- or "fork"- like loose tissue structures. CONCLUSION: MCP can be observed in different pathological types of ovarian tumors and can be used as a novel sonographic marker to differentiate between BOTs, benign tumors and malignant tumors. MCP may arise as a result of anechoic cystic fluid filling the loose tissue gap.

Cryoablation is superior to radiofrequency ablation for the treatment of non-small cell lung cancer: A meta-analysis.

This meta-analytical study compared the efficacy of cryoablation and radiofrequency ablation (RFA) in treating non-small cell lung cancer (NSCLC). We searched PubMed, Cochrane, Embase, and Web of Science™ for all relevant articles published until April 2022 that compared the efficacy of RFA and cryoablation in treating NSCLC. We used the Cochrane evaluation tool to assess the risk of bias. The fixed- or random-effects models were used, when appropriate. The primary outcome was a 3-year disease-free survival, whereas recurrence rate and complication rates were secondary outcomes. There were 340 patients divided across the seven studies we included in our meta-analysis. Based on the continuous-type variable analysis, cryoablation was superior to RFA in terms of 3-year disease-free survival (P = 0.003) and complication (P ＜ 0.00001) rates. Similarly, significant reductions in cryoablation were found for recurrence rates (P = 0.05) compared with RFA. Overall, cryoablation was superior to RFA in terms of prognosis and lifespan, regardless of whether systemic metastases occurred in non-small cell lung cancer.

Superparamagnetic iron oxide nanoparticles target BxPC-3 cells and silence MUC4 for the treatment of pancreatic cancer.

PURPOSE: Superparamagnetic iron oxide nanoparticles (SPION) are excellent magnetic resonance imaging (MRI) contrast agents. Mucin 4 (MUC4) acts as pancreatic cancer (PC) tumor antigen and influences PC progression. Small interfering RNAs (siRNAs) are used as a gene-silencing tool to treat a variety of diseases. METHODS: We designed a therapeutic probe based on polyetherimide-superparamagnetic iron oxide nanoparticles (PEI-SPION) combined with siRNA nanoprobes (PEI-SPION-siRNA) to assess the contrast in MRI. The biocompatibility of the nanocomposite, and silencing of MUC4 were characterized and evaluated. RESULTS: The prepared molecular probe had a particle size of 61.7 ± 18.5 nm and a surface of 46.7 ± 0.8mV and showed good biocompatibility in vitro and T2 relaxation efficiency. It can also load and protect siRNA. PEI-SPION-siRNA showed a good silencing effect on MUC4. CONCLUSION: PEI-SPION-siRNA may be beneficial as a novel theranostic tool for PC.

Different subtypes of ultrasound-diagnosed adenomyosis and in vitro fertilization outcomes: A systematic review and meta-analysis.

INTRODUCTION: Adenomyosis prevalence among women with infertility is increasing; their management during in vitro fertilization is usually based on ultrasound diagnosis alone. Herein, we summarize the latest evidence on the impact of ultrasound-diagnosed adenomyosis on in vitro fertilization outcomes. MATERIAL AND METHODS: The study was registered with The International Prospective Register of Systematic Reviews (CRD42022355584). We searched PubMed, Embase, and Cochrane Library databases from inception to January 31, 2023, for cohort studies on the impact of adenomyosis on in vitro fertilization outcomes. Fertility outcomes were compared according to the presence of adenomyosis as diagnosed by ultrasound, concurrent endometriosis and adenomyosis, and MRI-based or MRI- and ultrasound-based adenomyosis diagnosis. Live birth rate was the primary outcome while clinical pregnancy and miscarriage rates were secondary outcomes. RESULTS: Women diagnosed with adenomyosis by ultrasound had lower live birth (odds ratio [OR] = 0.66; 95% confidence interval [CI]: 0.53-0.82, grade: very low), lower clinical pregnancy (OR = 0.64; 95% CI: 0.53-0.77, grade: very low), and higher miscarriage (OR = 1.81; 95% CI: 1.35-2.44, grade: very low) rates than those without adenomyosis. Notably, symptomatic and diffuse, but not asymptomatic adenomyosis as diagnosed by ultrasound, adversely affected in vitro fertilization outcomes, with lower live birth (OR = 0.57; 95% CI: 0.34-0.96, grade: very low), clinical pregnancy (OR = 0.69; 95% CI: 0.57-0.85, grade: low), and miscarriage (OR = 2.48, 95% CI: 1.28-4.82, grade: low) rates; and lower live birth (OR = 0.37; 95% CI: 0.23-0.59, grade: low) and clinical pregnancy (OR = 0.50; 95% CI: 0.34-0.75, grade: low), but not miscarriage rate (OR = 2.18; 95% CI: 0.72-6.62, grade: very low), respectively. Concurrent adenomyosis in endometriosis is associated with a significantly lower live birth rate (OR = 0.44; 95% CI: 0.26-0.75, grade: low) than endometriosis alone. Finally, the use of MRI-based or MRI- and ultrasound-based adenomyosis diagnosis showed no significant association with in vitro fertilization outcomes (grade: very low for all outcomes). CONCLUSIONS: Considering ultrasound findings, symptoms, and different subtypes of adenomyosis may aid in offering personalized counseling, improving treatment decisions, and achieving better outcomes of in vitro fertilization.

A study of the diagnostic value of a modified transthoracic lung ultrasound scoring method in interstitial lung disease.

Background: Interstitial lung disease (ILD) is a serious complication of connective tissue disease (CTD) with significant morbidity and mortality. Lung ultrasound (LUS) has been widely used in the diagnosis of a variety of lung diseases. However, there is no standard ultrasound scanning method or scoring method for connective tissue disease associated with interstitial lung disease (CTD-ILD); therefore, it is necessary to establish a set of standard evaluation methods. Methods: A total of 60 consecutive patients with clinically confirmed CTD and suspected ILD were prospectively included in this study. LUS and high-resolution computed tomography (HRCT) were used to examine all patients. The time between HRCT and LUS examinations was less than 2 weeks. The ultrasonographic results were evaluated with the modified scoring method and the Buda scoring method. The imaging results were evaluated with the HRCT Warrick scoring method. The primary aim was to evaluate the diagnostic value of a modified ultrasound scoring method in CTD-ILD. Results: The results of the Youden index for the diagnosis of CTD-ILD by the modified method, the Buda method, and the HRCT method were 0.845, 0.711, and 0.911, respectively, with areas under the receiver operating characteristic (ROC) curve (AUC) of 0.982 [95% confidence interval (CI): 0.945-1.000], 0.950 (95% CI: 0.851-0.990), and 0.985 (95% CI: 0.949-1.000), respectively. With a clinical diagnosis as the gold standard, the consistency of the modified method and the HRCT method for CTD-ILD was high (Kappa values =0.872 and 0.913, respectively). The values of the modified method and the Buda method consistently and significantly increased with the increasing severity of CTD-ILD. For the former, there were significant differences between the mild, moderate, and severe groups (P<0.05). The ROC curve used to calculate the modified ultrasound score predicted the critical values of mild and severe pulmonary fibrotic lesions at 34 points (sensitivity, 100%; specificity, 92.9%; AUC =0.933; 95% CI: 0.807-1.000) and 64.5 points (sensitivity, 92.0%; specificity, 85.3%; AUC =0.972; 95% CI: 0.929-1.000). Conclusions: The modified ultrasound method has a higher diagnostic value than the Buda method for CTD-ILD.

Efficacy of Transabdominal Ultrasound-guided Percutaneous Microwave Ablation in the Treatment of Symptomatic Adenomyosis: A Retrospective Cohort Study.

STUDY OBJECTIVE: To evaluate and compare the clinical efficacy of transabdominal ultrasound-guided percutaneous microwave ablation (PMWA) in the treatment of symptomatic focal and nonfocal adenomyosis. DESIGN: Retrospective cohort study. SETTING: Longyan First Affiliated Hospital of Fujian Medical University. PATIENTS: From May 2019 to October 2021, 107 patients with symptomatic adenomyosis who refused hysterectomy received PMWA. INTERVENTIONS: Patients were divided into a focal group (n = 47, including 40 focal adenomyosis and 7 adenomyoma cases) and a nonfocal group (n = 60, including 36 diffuse and 24 mixed adenomyosis cases) according to the extent of lesion involvement. MEASUREMENTS AND MAIN RESULTS: We collected and analyzed preoperative baseline data on patient characteristics; postoperative efficacy measures at 3, 6, and 12 months; and intraoperative and postoperative complications. There was a significant post-treatment reduction in the uterine corpus volume and cancer antigen 125 levels, an increase in hemoglobin levels, and an improvement in the Uterine Fibroid Symptom and Health-related Quality of Life scores (consisting of the Symptom Severity Scale and the Health-related Quality of Life scale), dysmenorrhea visual analog scale, and menstrual volume score (MVS) (all p <.05). One patient had recurrence. Most adverse events (72.0%) were mild. Although the nonfocal group had significantly greater anemia severity, higher Symptom Severity Scale and MVS, lower Health-related Quality of Life scale, greater extent and severity of myometrial involvement, and larger uterine corpus volume, after treatment, the uterine corpus volume, uterine corpus reduction rate, cancer antigen 125 levels, hemoglobin levels, Uterine Fibroid Symptom and Health-related Quality of Life score, dysmenorrhea visual analog scale, MVS score, and clinical response rate were similar between the groups (p >.05). CONCLUSION: PMWA had good, similar, short-term efficacy for symptomatic focal and nonfocal adenomyosis.

Intraoperative ultrasound-guided percutaneous hepatocholangiostomy applied in the cholangioscopic lithotripsy for hepatolithiasis and choledocholithiasis.

BACKGROUND: Percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) is a minimally invasive treatment for hepatolithiasis. But it may make a long cycle of treatment so that it was further improved to complete the percutaneous hepatic choledochotomy and choledochoscopic lithotripsy in phase I surgery. The aim of this study was to evaluate the efficacy of the modified technique comparing with laparoscopic choledochotomy. METHODS: Retrospective analysis of the clinical data of patients with hepatolithiasis or choledocholithiasis consulted at our hospital from February 2018 to December 2021. The cases were divided into two groups according to surgical modality, intraoperative ultrasound-guided percutaneous transhepatic cholangioscopic lithotripsy (IUG-PTCSL) and laparoscopic choledochotomy lithotripsy (LC-L). Contrast analysis determined the advantages of the two approaches. RESULTS: IUG-PTCSL was performed in 44 patients, aged 58.14 ± 14.01 years, including 9 male and 35 female. There were 15 patients underwent LC-L, aged 62.13 ± 15.03 years, including 1 male and 14 female. There was not statistically significant difference in the composition of patients' age and sex between the two groups (p = 0.356, 0.219). The success rate of intraoperative ultrasound-guided percutaneous hepatic bile duct puncture was 100% followed with the success rate of hepatocholangiostomy was 100%. Although 1 (1/44) patient showed significant bleeding during choledochoscopic lithotripsy and was converted to open choledochotomy for stone extraction, 43 patients completed IUG-PTCSL with the rate of phase I surgical stones removal was 81.40% (35/43), whereas the stones removal rate of LC-L was 66.67% (10/15). There was not statistically significant difference between them (p = 0.067). Both the groups showed no significant complications with the postoperative hospital stay of 8 (6, 10) days and 10 (8, 11) days, respectively, and the difference was statistically significant (p = 0.028). CONCLUSION: Intraoperative ultrasound-guided percutaneous transhepatic cholangioscopy might be a safe and reliable ideal method for bile duct stones with the advantages of rapid recovery for patients. Intraoperative ultrasound-guided percutaneous hepatocholangiostomy may be the key technique for the successful completion of the surgery.
