Abstract
Purpose
To develop machine learning-based radiomics models derive from different MRI sequences for distinction between benign and malignant PI-RADS 3 lesions before intervention, and to cross-institution validate the generalization ability of the models.

Methods
The pre-biopsy MRI datas of 463 patients classified as PI-RADS 3 lesions were collected from 4 medical institutions retrospectively. 2347 radiomics features were extracted from the VOI of T2WI, DWI and ADC images. The ANOVA feature ranking method and support vector machine classifier were used to construct 3 single-sequence models and 1 integrated model combined with the features of three sequences. All the models were established in the training set and independently verified in the internal test and external validation set. The AUC was used to compared the predictive performance of PSAD with each model. Hosmer–lemeshow test was used to evaluate the degree of fitting between prediction probability and pathological results. Non-inferiority test was used to check generalization performance of the integrated model.

Results
The difference of PSAD between PCa and benign lesions was statistically significant (P = 0.006), with the mean AUC of 0.701 for predicting clinically significant prostate cancer (internal test AUC = 0.709 vs. external validation AUC = 0.692, P = 0.013) and 0.630 for predicting all cancer (internal test AUC = 0.637 vs. external validation AUC = 0.623, P = 0.036). T2WI-model with the mean AUC of 0.717 for predicting csPCa (internal test AUC = 0.738 vs. external validation AUC = 0.695, P = 0.264) and 0.634 for predicting all cancer (internal test AUC = 0.678 vs. external validation AUC = 0.589, P = 0.547). DWI-model with the mean AUC of 0.658 for predicting csPCa (internal test AUC = 0.635 vs. external validation AUC = 0.681, P = 0.086) and 0.655 for predicting all cancer (internal test AUC = 0.712 vs. external validation AUC = 0.598, P = 0.437). ADC-model with the mean AUC of 0.746 for predicting csPCa (internal test AUC = 0.767 vs. external validation AUC = 0.724, P = 0.269) and 0.645 for predicting all cancer (internal test AUC = 0.650 vs. external validation AUC = 0.640, P = 0.848). Integrated model with the mean AUC of 0.803 for predicting csPCa (internal test AUC = 0.804 vs. external validation AUC = 0.801, P = 0.019) and 0.778 for predicting all cancer (internal test AUC = 0.801 vs. external validation AUC = 0.754, P = 0.047).

Conclusions
The radiomics model based on machine learning has the potential to be a non-invasive tool to distinguish cancerous, noncancerous and csPCa in PI-RADS 3 lesions, and has relatively high generalization ability between different date set.

Published: March 2023

Abstract
Background
The optimal treatment for cerebral infarction caused by posterior circulation occlusion of large vessels has not yet been determined. Intravascular interventional therapy is an important treatment for cerebral infarction with posterior circulation occlusion of large vessels. However, endovascular therapy (EVT) of some posterior circulation cerebrovascular is ineffective and eventually become futile recanalization. Therefore, we performed a retrospective study to explore the factors influencing futile recanalization after EVT in patients with posterior circulation large-vessel occlusion.

Methods
Eighty-six patients with acute cerebral infarction and posterior circulation large vessel occlusion after intravascular intervention were divided into two groups according to their modified Rankin scale (mRS) scores after 3 months: group 1, mRS scores less than or equal to 3 (the effective recanalization group); group 2, mRS scores greater than 3 (the ineffective recanalization group). The basic clinical data, imaging index scores, time from onset to recanalization, and operation time between the two groups were compared and analyzed. Logistic regression was used to analyze the factors influencing indicators of good prognosis, and the ROC curve and Youden index were used to determine the best cutoff value.

Results
Between the two groups, there were significant differences in the posterior circulation CT angiography (pc-CTA) scores, GCS scores, pontine midbrain index scores, time from discovery to recanalization, operation time, NIHSS score and incidence of gastrointestinal bleeding. The logistic regression revealed that the NIHSS score and time from discovery to recanalization were associated with good prognoses.

Conclusion
NIHSS score and recanalization time were independent influencing factors of ineffective recanalization of cerebral infarctions caused by posterior circulation occlusion. EVT is relatively effective for cerebral infarction caused by posterior circulation occlusion when the NIHSS score is less than or equal to 16 and the time from onset to recanalization is less than or equal to 570 min.
Inhaled nitric oxide in premature infants for preventing bronchopulmonary dysplasia: a meta-analysis
Authors: Zheng Yi , Wu Qi , Han Shuping 
Published: March 2023

Abstract
Background
The effectiveness of nitric oxide (NO) in reducing the risk of bronchopulmonary dysplasia (BPD) remains debatable. In this study, we performed a meta-analysis to guide clinical decision-making regarding the significance of inhaled NO (iNO) on the potential occurrence and outcomes of BPD in premature infants.

Methods
Data from clinical randomized controlled trials (RCTs) published in PubMed, Embase, Cochrane Library, Wanfang, China National Knowledge Infrastructure (CNKI) and Chinese Scientific Journal Database VIP databases for premature infants were searched from inception to March 2022. Review Manager 5.3 statistical software was used for heterogeneity analysis.

Results
Of the 905 studies retrieved, 11 RCTs met the screening criteria of this study. Our analysis showed that the iNO group was associated with a significantly lower incidence of BPD than the control group (relative risk [RR] = 0.91, 95% confidence interval (CI) 0.85-0.97, P = 0.006). We also observed no significant difference in the incidence of BPD between the two groups at the initial dose of 5 ppm (ppm) (P = 0.09) but those treated with 10 ppm iNO had a significantly lower incidence of BPD (RR = 0.90, 95%CI 0.81-0.99, P = 0.03). However, it should be noted that although the iNO group had an increased risk for necrotizing enterocolitis (NEC) (RR = 1.33, 95%CI 1.04-1.71, P = 0.03), cases treated with an initial dose of 10 ppm revealed no significant difference in the incidence of NEC compared with the control group (P = 0.41), while those treated with an initial dosage of 5 ppm of iNO had a significantly greater NEC rates than the control group (RR = 1.41, 95%CI 1.03-1.91, P = 0.03). Further, we observed no statistically significant differences in the incidence of in-hospital mortality, intraventricular hemorrhage (IVH) (Grade 3/4) or periventricular leukomalacia (PVL) and pulmonary hemorrhage (PH) between the two treatment groups.

Conclusions
This meta-analysis of RCTs showed that iNO at an initial dosage of 10 ppm seemed more effective in reducing the risk of BPD than conventional treatment and iNO at an initial dosage of 5 ppm in preterm infants at a gestational age of ≤34 weeks who required respiratory support. However, the incidence of in-hospital mortality and adverse events between the overall iNO group and Control were similar.

Published: March 2023

Abstract
Background
A number of differences in joint attention behaviour between children with autism spectrum disorder (ASD) and typically developing (TD) individuals have previously been documented.

Method
We use eye-tracking technology to assess response to joint attention (RJA) behaviours in 77 children aged 31 to 73 months. We conducted a repeated-measures analysis of variance to identify differences between groups. In addition, we analysed correlations between eye-tracking and clinical measures using Spearman’s correlation.

Results
The children diagnosed with ASD were less likely to follow gaze compared to TD children. Children with ASD were less accurate at gaze following when only eye gaze information was available, compared to when eye gaze with head movement was observed. Higher accuracy gaze-following profiles were associated with better early cognition and more adaptive behaviours in children with ASD. Less accurate gaze-following profiles were associated with more severe ASD symptomatology.

Conclusion
There are differences in RJA behaviours between ASD and TD preschool children. Several eye-tracking measures of RJA behaviours in preschool children were found to be associated with clinical measures for ASD diagnosis. This study also highlights the construct validity of using eye-tracking measures as potential biomarkers in the assessment and diagnosis of ASD in preschool children.
Mental health experiences and coping strategies of BAME care workers who worked in nursing and residential care homes during the COVID-19 pandemic in Luton, England

Published: March 2023

Abstract
Background
The COVID-19 pandemic intensified the risk factors for poor mental health among care workers in the UK. However, there is inadequate evidence on the mental health impact of COVID-19 on Black, Asian, and minority ethnic (BAME) care workers in particular. This study seeks to explore mental health experiences and coping strategies of BAME care workers who worked in nursing and residential care homes during the COVID-19 pandemic.

Method
This is a qualitative study conducted between February and May, 2021 in Luton, England. A sample of n = 15 care workers from BAME background working in nursing and residential care homes were recruited purposively using the snowball sampling technique. In-depth interviews were conducted around topics such as views on COVID-19, the impact of the COVID-19 pandemic on mental health and coping during the COVID-19 pandemic. Data from the interviews was analysed using the Framework Analysis Approach.

Results
The COVID-19 pandemic had a negative impact on the participants’ mental health as they experienced stress, depression, anxiety, trauma and paranoia. The majority of the participants explained that they managed their mental health by belief in God and religious practices, by keeping themselves busy doing activities they were passionate about, following government guidelines on the prevention of COVID-19, seeing the service users happy and some participants managed through support that was offered by the government. However, some participants did not have any support for their mental health.

Conclusion
Issues such as increased workload associated with COVID-19 restrictions engendered mental health problems among BAME care workers, however, the workload only further increased during the pandemic, but the health and social care sector was already affected by heavy workload due to staff shortages and this needs to be addressed through increasing their wages to encourage more people to work in the health and social care sector. In addition, some BAME care workers never received any support for their mental health during the pandemic. Hence, integrating mental health services such as counselling, supportive psychotherapy and recreational therapies in care homes could help to support the mental health of care workers in the COVID-19 era.

Published: March 2023

Abstract
Background
The global extant literature acknowledge that housing serves as a key social determinant of health. Housing interventions that involve group homes have been found to support the recovery of persons with mental illness and those with addiction issues. The current study explored the views of homeowners in relation to a supportive housing program called Community Homes for Opportunity (CHO) that modernised a provincial group home program (Homes for Special Care [HSC]) and provided recommendations for improving the program implementation in other geographical areas of Ontario.

Methods
We applied ethnographic qualitative techniques to purposefully recruit 36 homeowner participants from 28 group homes in Southwest Ontario, Ontario Canada. Focus group discussions were conducted at two time points, during CHO program implementation (Fall 2018, and post implementation phases (Winter 2019) respectively.

Results
Data analysis yielded 5 major themes. These include: (1) general impressions about the modernization process, (2) perceived social, economic and health outcomes, (3) enablers of the modernization program, (4) challenges to implementation of the modernization program, and (5) suggestions for implementation of the CHO in future.

Conclusions
A more effective and expanded CHO program will need the effective collaboration of all stakeholders including homeowners for successful implementation.

Abstract
Background
Although a relationship between chronic obstructive pulmonary disease (COPD) and dementia has been reported, the initial severity upon emergency department (ED) visits and the medications used have not been well evaluated as risk factors for increased dementia occurrence. We aimed to analyze the risks of dementia development over 5 years among patients with COPD compared to matched controls (primary) and the impact of different severities of acute exacerbations (AEs) of COPD and medications on the risk of dementia development among COPD patients (secondary).

Method
This study used the Taiwanese government deidentified health care database. We enrolled patients during the 10-year study period (January 1, 2000, to December 31, 2010), and each patient was followed up for 5 years. Once these patients received a diagnosis of dementia or died, they were no longer followed up. The study group included 51,318 patients who were diagnosed with COPD and 51,318 matched (in terms of age, sex, and the number of hospital visits) non-COPD patients from the remaining patients as the control group. Each patient was followed up for 5 years to analyze the risk of dementia with Cox regression analysis. Data on medications (antibiotics, bronchodilators, corticosteroids) and severity at the initial ED visit (ED treatment only, hospital admission, or ICU admission) were collected for both groups, as well as demographics and baseline comorbidities, which were considered confounding factors.

Results
In the study and control groups, 1,025 (2.0%) and 423 (0.8%) patients suffered from dementia, respectively. The unadjusted HR for dementia was 2.51 (95% CI: 2.24–2.81) in the study group. Bronchodilator treatment was associated with the HRs, especially among those who received long-term (> 1 month) treatment (HR = 2.10, 95% CI: 1.91–2.45). Furthermore, among 3,451 AE of COPD patients who initially visited the ED, patients who required ICU admission (n = 164, 4.7%) had a higher risk of dementia occurrence (HR = 11.05, 95% CI: 7.77–15.71).

Conclusion
Bronchodilator administration might be associated with a decreased risk of dementia development. More importantly, patients who suffered AEs of COPD and initially visited the ED and required ICU admission had a higher risk of developing dementia.
Primary mitochondrial disease as a rare cause of unclear breathlessness and distinctive performance degradation – a case report
Authors: Ewert Ralf , Elhadad Mohamed A. , Habedank Dirk , Heine Alexander , Stubbe Beate 
Published: March 2023

Abstract
Background
Primary muscular disorders (metabolic myopathies, including mitochondrial disorders) are a rare cause of dyspnea. We report a case of dyspnea caused by a mitochondrial disorder with a pattern of clinical findings that can be classified in the known pathologies of mitochondrial deletion syndrome.

Case presentation
The patient presented to us at 29 years of age, having had tachycardia, dyspnea, and functional impairment since childhood. She had been diagnosed with bronchial asthma and mild left ventricular hypertrophy and treated accordingly, but her symptoms had worsened. After more than 20 years of progressive physical and social limitations was a mitochondrial disease suspected in the exercise testing. We performed cardiopulmonary exercise testing (CPET) with right heart catheterization showed typical signs of mitochondrial myopathy. Genetic testing confirmed the presence of a ~ 13 kb deletion in mitochondrial DNA from the muscle. The patient was treated with dietary supplements for 1 year. In the course of time, the patient gave birth to a healthy child, which is developing normally.

Conclusion
CPET and lung function data over 5 years demonstrated stable disease. We conclude that CPET and lung function analysis should be used consistently to evaluate the cause of dyspnea and for long-term observation.

Abstract
Background
The evidence of prognostic factors and individualized surveillance strategies for upper tract urothelial carcinoma are still weak.

Objectives
To evaluate whether the history of previous malignancy (HPM) affects the oncological outcomes of upper tract urothelial carcinoma (UTUC).

Methods
The CROES-UTUC registry is an international, observational, multicenter cohort study on patients diagnosed with UTUC. Patient and disease characteristics from 2380 patients with UTUC were collected. The primary outcome of this study was recurrence-free survival. Kaplan-Meier and multivariate Cox regression analyses were performed by stratifying patients according to their HPM.

Results
A total of 996 patients were included in this study. With a median recurrence-free survival time of 7.2 months and a median follow-up time of 9.2 months, 19.5% of patients had disease recurrence. The recurrence-free survival rate in the HPM group was 75.7%, which was significantly lower than non-HPM group (82.7%, P = 0.012). Kaplan-Meier analyses also showed that HPM could increase the risk of upper tract recurrence (P = 0.048). Furthermore, patients with a history of non-urothelial cancers had a higher risk of intravesical recurrence (P = 0.003), and patients with a history of urothelial cancers had a higher risk of upper tract recurrence (P = 0.015). Upon multivariate Cox regression analysis, the history of non-urothelial cancer was a risk factor for intravesical recurrence (P = 0.004), and the history of urothelial cancer was a risk factor for upper tract recurrence (P = 0.006).

Conclusion
Both previous non-urothelial and urothelial malignancy could increase the risk of tumor recurrence. But different cancer types may increase different sites’ risk of tumor recurrence for patients with UTUC. According to present study, more personalized follow-up plans and active treatment strategies should be considered for UTUC patients.

Published: March 2023

Abstract
Background
Pelvic organ prolapse is a bothersome condition affecting many women at advanced age, but also frequently observed in young women with certain risk factors. Various surgical techniques have been developed with the aim of providing effective surgical treatment for apical prolapse. The vaginal bilateral sacrospinous colposuspension surgery (BSC) with ultralight mesh and utilization of the i- stich is a relatively new minimal invasive technique with very promising outcomes. The technique offers apical suspension, in the presence or absence of the uterus. The objective of this study is to evaluate the anatomical and functional outcomes of bilateral sacrospinous colposuspension with ultralight mesh in 30 Patients treated with the vaginal single incision standardized technique.

Methods
In this retrospective study, 30 patients were treated by BSC for significant vaginal, uterovaginal or cervical prolapse. A simultaneous anterior colporrhaphy, posterior colporrhaphy or both were performed when indicated. Anatomical and functional outcomes were assessed 1 year postoperatively using the Pelvic Organ Prolapse Quantification system (POP-Q) and the standardised Prolapse Quality of Life (P-QOL) questionnair.

Results
The POP-Q parameters were significantly improved at twelve months after surgery compared to baseline. The total score and all four subdomains of the P-QOL-questionnaire showed positive trends and improvement at twelve months after surgery when compared to preoperative values. All patients were asymptomatic and expressed high satisfaction one year after surgery. No intraoperative adverse events were recorded for all patients. Only minimal postoperative complications were recorded and they all resolved completely with conservative management.

Conclusion
This study highlights the functional and anatomical outcomes of the minimally invasive vaginal bilateral sacrospinal colposuspension with ultralight mesh for the management of apical prolapse. The one year postoperative results of the proposed procedure reflect excellent outcomes with minimal complications. The data published here are very promising and warrant further investigations and more studies to evaluate the long-term outcomes of BSC in the surgical management of apical defects.

Trial registration
The study protocol was approved by the Ethics Committee at the University Hospital of Cologne, Germany (Date of registration: 08.02.2022) (Registration number: 21-1494-retro) (retrospectively registered).
