Ultrasound-guided high-intensity focused ultrasound ablation for uterine arteriovenous fistula: a case series.

PURPOSE: To evaluate the efficacy and safety of high-intensity focused ultrasound (HIFU) ablation in the treatment of uterine arteriovenous fistula (UAVF). MATERIALS AND METHODS: This case series included three patients diagnosed with acquired UAVF. All patients underwent routine laboratory tests, electrocardiography (ECG), chest X-ray, ultrasound, and pelvic contrast-enhanced magnetic resonance imaging (MRI). HIFU treatment was performed under sedation and analgesia using a Model JC Focused Ultrasound Tumor Therapeutic System (made by Chongqing Haifu Medical Technology Co. Ltd., China) with a B mode ultrasound device for treatment guidance. The treatment time, sonication power, sonication time, and complications were recorded. Follow-up evaluations were scheduled at 1-, 3-, 6-, and 12-month to assess symptom improvement and evaluate the post-treatment imaging. RESULTS: All patients completed HIFU treatment in a single session without any major complication. All patients complained of mild lower abdominal and sacrococcygeal pain. Typically, no special treatment is required. Following HIFU treatment, there was a significant relief in clinical symptoms, particularly abnormal uterine bleeding. Ultrasound examinations conducted one month after the treatment revealed a notable reduction in the volume of the lesion, ranging from 57% to 100%. Moreover, the efficacy and safety of HIFU treatment remained consistent during the 12-month follow-up period. CONCLUSION: HIFU ablation appears to be an effective and safe treatment modality for UAVF. It provides a noninvasive approach with favorable clinical outcomes.

A qualitative study of the factors impacting implementation of the national action plan to contain antimicrobial resistance (2016-2020) in medical institutions.

OBJECTIVE: Antimicrobial resistance (AMR) has emerged as a serious global public health crisis. In response, 2016, 14 ministries in China, under the leadership of the National Health Commission, collaboratively issued the National Action Plan (NAP) to Contain Antibacterial Resistance (2016-2020). The NAP outlines strategies for medical institutions to adopt stewardship and implement AMR control. The purpose of this study was to comprehend stakeholders' perceptions of the NAP and explore the factors that influence its implementation in medical institutions. METHODS: Semi-structured interviews were conducted with practitioners from medical institution in March and April 2021. Interviews were audio-recorded, transcribed and analyzed using thematic analysis via the framework approach. RESULTS: Twenty practitioners, representing diverse roles (4 administrators, 7 clinicians, 3 microbiologists, 3 pharmacists, 3 nosocomial infection management personnel) from seven institutions, participated in the study. Substantial efforts have been undertaken to regulate the rational use of antibiotics and enhance the management of hospital infections. Participants demonstrated awareness and concern regarding antimicrobial resistance, with widespread support expressed for the NAP. Among all professions, there were varying opinions on whether they felt restricted in their daily work. The tertiary hospitals have established multidisciplinary cooperation mechanisms. Six main themes were identified as both barriers and facilitators to the implementation of the NAP in the medical institutions: individual factors, leadership, multidisciplinary collaboration, patient factors, training and culture. The capacity for administrative attention is constrained or limited, poor enforcement of guidelines, insufficient specialist staff and the liability pressure on clinicians were perceived barriers. To containing AMR in medical institutions, management of hospital infections, the public's knowledge of antibiotics' usage, routine education and multidisciplinary support would be facilitators. CONCLUSIONS: Practitioners from medical institutions were highly supportive for the NAP. Consideration of practitioners' perceived barriers and facilitators might enhance implementation of the NAP to contain antimicrobial resistance.

The anchor design of anchor-based method to determine the minimal clinically important difference: a systematic review.

BACKGROUND: Positive results for clinical outcomes should be not only statistically significant, but also clinically significant. The minimum clinically important difference (MCID) is used to define the minimum threshold of clinical significance. The anchor-based method is a classical method for ascertaining MCID. This study aimed to summarise the design of the anchors of the anchor-based method by reviewing the existing research and providing references and suggestions. METHOD: This study was mainly based on literature research. We performed a systematic search using Web of Science, PubMed, CNKI, Wanfang, and VIP databases. Two reviewers independently screened titles and abstracts to identify relevant articles. Data were extracted from eligible articles using a predefined data collection form. Discrepancies were resolved by discussion and the involvement of a third reviewer. RESULT: Three hundred and forty articles were retained for final analysis. For the design of anchors, Subjective anchors (99.12%) were the most common type of anchor used, mainly the Patient's rating of change or patient satisfaction (66.47%) and related scale health status evaluation items or scores (39.41%). Almost half of the studies (48.53%) did not assess the correlation test between the anchor and the research indicator or scale. The cut-off values and grouping were usually based on the choice of the anchor types. In addition, due to the large number of included studies, this study selected the most calculated SF-36 (28 articles) for an in-depth analysis. The results showed that the overall design of the anchor and the cut-off value were the same as above. The statistical methods used were mostly traditional (mean change, ROC). The MCID thresholds of these studies had a wide range (SF-36 PCS: 2-17.4, SF-36 MCS: 1.46-10.28), and different anchors or statistical methods lead to different results. CONCLUSION: It is of great importance to select several types of anchors and to use more reliable statistical methods to calculate the MCID. It is suggested that the order of selection of anchors should be: objective anchors > anchors with established MCID in subjective anchors (specific scale > generic scale) > ranked anchors in subjective anchors. The selection of internal anchors should be avoided, and anchors should be evaluated by a correlation test.

CCL2 is a key regulator and therapeutic target for periodontitis.

AIM: Our previous study revealed that the C-C motif chemokine receptor 2 (CCR2) is a promising target for periodontitis prevention and treatment. However, CCR2 is a receptor with multiple C-C motif chemokine ligands (CCLs), including CCL2, CCL7, CCL8, CCL13 and CCL16, and which of these ligands plays a key role in periodontitis remains unclear. The aim of the present study was to explore the key functional ligand of CCR2 in periodontitis and to evaluate the potential of the functional ligand as a therapeutic target for periodontitis. MATERIALS AND METHODS: The expression levels and clinical relevance of CCR2, CCL2, CCL7, CCL8, CCL13 and CCL16 were studied using human samples. The role of CCL2 in periodontitis was evaluated by using CCL2 knockout mice and overexpressing CCL2 in the periodontium. The effect of local administration of bindarit in periodontitis was evaluated by preventive and therapeutic medication in a mouse periodontitis model. Microcomputed tomography, haematoxylin and eosin staining, tartrate-resistant acid phosphatase staining, real-time quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, bead-based immunoassays and flow cytometry were used for histomorphology, molecular biology and cytology analysis. RESULTS: Among different ligands of CCR2, only CCL2 was significantly up-regulated in periodontitis gingival tissues and was positively correlated with the severity of periodontitis. Mice lacking CCL2 showed milder inflammation and less bone resorption than wild-type mice, which was accompanied by a reduction in monocyte/macrophage recruitment. Adeno-associated virus-2 vectors overexpressing CCL2 in Ccl2-/- mice gingiva reversed the attenuation of periodontitis in a CCR2-dependent manner. In ligation-induced experimental periodontitis, preventive or therapeutic administration of bindarit, a CCL2 synthesis inhibitor, significantly inhibited the production of CCL2, decreased the osteoclast number and bone loss and reduced the expression levels of proinflammatory cytokines TNF-α, IL-6 and IL-1ß. CONCLUSIONS: CCL2 is a pivotal chemokine that binds to CCR2 during the progression of periodontitis, and targeting CCL2 may be a feasible option for controlling periodontitis.

Effect evaluation and influencing factor analysis of vaginal carbon dioxide laser in the treatment of stress urinary incontinence.

To evaluate the clinical efficacy of carbon dioxide laser in the treatment of female stress urinary incontinence and analyze the influencing factors. A total of 46 patients with stress urinary incontinence treated in the Affiliated Hospital of Nantong University from March 2021 to August 2022 were included through strict inclusion criteria and exclusion criteria. All patients were treated with transvaginal carbon dioxide laser therapy, and Patient Global Impression of Change (PGI-C) was used to evaluate patients' subjective satisfaction after treatment. The efficacy was evaluated by patient's subjective assessment of leakage, IngelmanSundberg scale, 1-h urine pad test, and international consultation on incontinence questionnaire short form (ICI-Q-SF) before and after treatment, and the adverse reactions after treatment were recorded. The treatment effect was divided into "significant effect group" and "no significant effect group" by subjective satisfaction and post-treatment-related scale evaluation. After laser treatment, patients' subjective symptom improved, the volume of 1-h urine pad test was reduced, and the ICI-Q-SF score was decreased, and the differences were statistically significant (P < 0.05). There was no significant difference in IngelmanSundberg scale before and after treatment (P = 1.00). Multivariate logistic regression analysis showed that pad test volume was significantly correlated with treatment effect (P = 0.007). Transvaginal carbon dioxide laser is a safe and effective method for the treatment of mild to moderate stress urinary incontinence in females. The less severe the urinary leakage, the better the treatment effect.

Reconstruction of Hemifacial Congenital Giant Nevus with Pre-expanded Scalp Flaps and Deltopectoral Skin Flaps.

BACKGROUND: The hemifacial congenital giant nevus impacts both physical and mental health of the patients. Excision is typically the most suitable option in these situations, but reconstructing the subsequent surgical defects is always a serious challenge. METHODS: Between February 2012 and January 2021, a retrospective review of 4 patients who suffered from hemifacial congenital giant nevus was conducted, and they were treated by pre-expanded scalp flap and deltopectoral flap simultaneously. All patients receive tissue expansion, nevus resection, expanded skin flap transfer, and pedicle division. RESULTS: Four patients with hemifacial congenital giant nevi were successfully treated with no major complications. One patient with a transferred deltopectoral flap experienced distal necrosis of the flap, and healed after dressing changes. No recurrence of the nevus was found during the follow-up period, and the transferred skin flaps match well with facial skin in contour and color. CONCLUSION: This modified pre-expanded scalp flap combined with a deltopectoral flap provides an easy and reliable way for hemifacial reconstruction in patients with a congenital giant nevus.

We reported the comprehensive treatment of an elderly critically ill patient with pelvic fracture.The functions and quality of life of the patient were recovered after collaborative nursing by both family and hospital according to the general practice principle of both mental and physical rehabilitation.We summarized the diagnosis and treatment strategies of this case,aiming to provide reference for the clinical treatment of such cases.

A Structured Skin Care Protocol for Preventing and Treating Incontinence-associated Dermatitis in Critically Ill Patients.

OBJECTIVE: To examine the effectiveness of a structured skin care protocol for preventing and treating incontinence-associated dermatitis (IAD) in critically ill patients. METHODS: Participants were drawn from the ICUs of three teaching hospitals between January 2016 and December 2017. Patients were eligible if they were ≥18 years old, had idiopathic fecal incontinence, had diarrhea but were unable to sense it, and were expected to stay in the ICU for at least 72 hours after developing incontinence. A total of 143 patients were enrolled: 79 in the experimental group and 64 in the control group. In the first phase of the study, routine skin care measures were used; in the second phase, three ICU caregivers were trained to provide a structured skin care protocol. Trained research team members conducted the data collection and analysis. The TREND (Transparent Reporting of Evaluations with Nonrandomized Designs) Statement Checklist was followed in reporting the study results. RESULTS: Application of the structured skin care protocol reduced the incidence of IAD from 35.9% in the control phase to 17.7% in the intervention phase (χ2 = 6.117, P < .05) and also decreased the severity of IAD (z = -2.023, P < .05). Further, IAD developed later (z = -2.116, P < .05) in the intervention group than in the control group. In addition, the nursing times to prevent or manage IAD did not differ significantly between the groups (t = -0.258, P > .05; t = -1.190, P > .05). CONCLUSIONS: Use of the developed structured skin care protocol for IAD in critically ill patients lowered the incidence and severity of IAD and delayed IAD development.

Extra-pulmonary vein driver mapping and ablation for persistent atrial fibrillation in obese patients.

AIMS: The aim of this study was to determine whether driver ablation effectively treats persistent atrial fibrillation (AF) in obese patients. METHODS AND RESULTS: We randomly assigned 124 persistent AF obese patients to two groups, one undergoing conventional ablation (n = 62) and the other undergoing driver ablation (n = 62). Sixty-two non-obese patients with persistent AF undergoing driver ablation served as matched controls. Bipolar electrogram dispersion was analysed for driver mapping. Epicardial adipose tissue (EAT) volume was measured using cardiac computed tomography. Obese patients had a higher proportion of driver regions in the posterior wall (56.5% vs. 32.3%, P = 0.007). Driver complexity, measured as the average number and area of driver regions, was higher in the obese group than in the non-obese group (3.5 ± 1.0 vs. 2.9 ± 0.9, P < 0.001; 15.5% ± 4.2% vs. 9.8 ± 2.6%, P < 0.001, respectively). Left atrial EAT volume correlated better with the proportion of area of driver regions than did body mass index (BMI) and total EAT (BMI: r2 = 0.250, P < 0.001; total EAT: r2 = 0.379, P < 0.001; and left atrial EAT: r2 = 0.439, P < 0.001). The rate of AF termination was significantly higher in the driver ablation group than in the conventional ablation group (82.9% vs. 22.8%, P < 0.001). During the follow-up period of 16.9 ± 6.5 months, patients in the driver ablation group had significantly better AF-free survival (91.91% vs. 79.0%, log rank test, P = 0.026) and AF/atrial tachycardia-free survival (83.9% vs. 64.5%, log rank test, P = 0.011) than did patients in the conventional ablation group. CONCLUSION: Obesity is associated with increased driver complexity. Driver ablation improves long-term outcomes in obese patients with persistent AF.

Efficiency of complete omentectomy in patients with resectable gastric cancer: a meta­analysis and systematic review.

BACKGROUND: We performed a meta-analysis to investigate the efficacy of complete omentectomy (CO) in patients undergoing radical gastrectomy for gastric cancer. METHODS: We conducted a literature search in PubMed, Web of Science, and the Cochrane Library databases for clinical research that compared CO with non-complete omentectomy (NCO). These articles were published prior to April 2021. Overall survival (OS) rates, relapse-free survival (RFS) rates, recurrence rates, operation times, estimates of blood loss, numbers of harvested lymph nodes, complications, and lengths of hospital stays were compared using relative risks (RRs) and weighted mean differences (WMDs). RevMan 5.3 software was used for statistical analysis. RESULTS: Nine studies that included 3329 patients (1960 in the CO group) and 1369 in the NCO group comprised the analysis. The meta-analysis showed that CO was associated with a decreased 3-year OS rate (RR = 0.94, 95% CI 0.90-0.98, P = 0.005) and 5-year OS rate (RR = 0.93, 95% CI 0.88-0.98, P = 0.007). However, it was not associated with the 3-year RFS rate (RR = 0.97, 95% CI 0.90-1.04, P = 0.44), 5-year RFS (RR = 0.98, 95% CI 0.90-1.06, P = 0.60), or recurrence rate (RR = 1.17, 95% CI 0.95-1.45, P = 0.15) compared to the NCO group. For surgical-related outcomes, significant heterogeneity existed between the studies. Compared to the NCO group, CO was found to be associated with significantly more estimated blood loss (WMD = 250.90, 95% CI 105.90-396.28, P = 0.0007) and less harvested lymph nodes (WMD = - 3.59, 95% CI - 6.88, - 0.29, P = 0.03). Although, there was no significant difference in the surgical time (WMD = 15.93, 95% CI - 0.21, 32.07, P = 0.05). No statistically significant differences were observed in the rates of overall (P = 0.79) and major complications (P = 0.90), or the lengths of hospital stays (P = 0.11) between the two groups. CONCLUSIONS: Based on the available evidence, CO is not superior to NCO in terms of survival. CO is not recommended as a routine surgery for gastric cancer. Future well-designed high-quality RCTs are warranted.

An uncommon etiological factor for aspiration pneumonitis caused by spontaneous sphenoid sinus meningoencephalocele with cerebrospinal fluid rhinorrhea: a case report.

BACKGROUND: Aspiration pneumonitis is an inflammatory disease of the lungs which is difficult to diagnose accurately. Large-volume aspiration of oropharyngeal or gastric contents is essential for the development of aspiration pneumonitis. The role of cerebrospinal fluid (CSF) rhinorrhea is often underestimated as a rare etiological factor for aspiration in the diagnosis process of aspiration pneumonitis. CASE PRESENTATION: We present a case of a patient with 4 weeks of right-sided watery rhinorrhea accompanied by intermittent postnasal drip and dry cough as the main symptoms. Combined with clinical symptoms, imaging examination of the sinuses, and laboratory examination of nasal secretions, she was initially diagnosed as spontaneous sphenoid sinus meningoencephalocele with CSF rhinorrhea, and intraoperative endoscopic findings and postoperative pathology also confirmed this diagnosis. Her chest computed tomography showed multiple flocculent ground glass density shadows in both lungs on admission. The patient underwent endoscopic resection of meningoencephalocele and repair of skull base defect after she was ruled out of viral pneumonitis. Symptoms of rhinorrhea and dry cough disappeared, and pneumonitis was improved 1 week after surgery and cured 2 months after surgery. Persistent CSF rhinorrhea caused by spontaneous sphenoid sinus meningoencephalocele was eventually found to be a major etiology for aspiration pneumonitis although the absence of typical symptoms and well-defined risk factors for aspiration, such as dysphagia, impaired cough reflex and reflux diseases. CONCLUSIONS: We report a rare case of aspiration pneumonitis caused by spontaneous sphenoid sinus meningoencephalocele with CSF rhinorrhea, which can bring more attention and understanding to the uncommon etiology for aspiration, so as to make more accurate diagnosis of the disease and early surgical treatment.

Biogenesis of a 22-nt microRNA in Phaseoleae species by precursor-programmed uridylation.

Phased, secondary siRNAs (phasiRNAs) represent a class of small RNAs in plants generated via distinct biogenesis pathways, predominantly dependent on the activity of 22-nt miRNAs. Most 22-nt miRNAs are processed by DCL1 from miRNA precursors containing an asymmetric bulge, yielding a 22/21-nt miRNA/miRNA* duplex. Here we show that miR1510, a soybean miRNA capable of triggering phasiRNA production from numerous nucleotide-binding leucine-rich repeat (NB-LRRs), previously described as 21 nt in its mature form, primarily accumulates as a 22-nt isoform via monouridylation. We demonstrate that, in Arabidopsis, this uridylation is performed by HESO1. Biochemical experiments showed that the 3' terminus of miR1510 is only partially 2'-O-methylated because of the terminal mispairing in the miR1510/miR1510* duplex that inhibits HEN1 activity in soybean. miR1510 emerged in the Phaseoleae ∼41-42 million years ago with a conserved precursor structure yielding a 22-nt monouridylated form, yet a variant in mung bean is processed directly in a 22-nt mature form. This analysis of miR1510 yields two observations: (i) plants can utilize postprocessing modification to generate abundant 22-nt miRNA isoforms to more efficiently regulate target mRNA abundances; and (ii) comparative analysis demonstrates an example of selective optimization of precursor processing of a young plant miRNA.

How Doctors Do Things with Empathy in Online Medical Consultations in China: A Discourse-analytic Approach.

It is widely acknowledged that doctors' expressions of empathy are fundamental to a successful medical consultation. While extensive work has been done on empathic communication in face-to-face medical encounters, few studies explored expressions of empathy in online medical consultations. Such research is particularly scarce in Chinese contexts, even though China has recently seen substantial growth in e-healthcare activities. To gain a better understanding of clinical empathic communication in online environment, this study, using discourse-analytic tools, explores the pragmatic functions of doctors' empathic responses in text-based online medical consultations in China. The study finds that most empathic responses by doctors can be said to perform the function of facilitating the institutional task of problem-solving, and a few serve the function of self-promotion that is likely to be triggered by the e-commerce model for online medical services.

Is endoscopic drainage better than percutaneous drainage for patients with pancreatic fluid collections? A comparative meta-analysis.

INTRODUCTION: though endoscopic and percutaneous drainage have emerged as the most common minimally invasive treatments for pancreatic fluid collections (PFCs), estimates of therapeutic superiority for either treatment have yielded inconsistent results. METHODS: we retrieved studies comparing the efficacy and safety of these two approaches in PubMed, Embase, and the Cochrane Library. Primary outcomes were differences in technical success, clinical success, and adverse events, and secondary outcomes included differences in reintervention, need for surgical intervention, mortality, recurrence rate, and length of hospital stay. RESULTS: there were nonsignificant differences in technical success rate (OR 0.54; CI: 0.15-1.86), clinical success rate (OR 1.39; CI: 0.82-2.37), adverse events rate (OR 1.21; CI: 0.70-2.11), mortality rate (OR 0.81; CI: 0.30-2.16), and recurrence rate (OR 1.94; CI 0.74-5.07) between the two groups. Reintervention rate (OR 0.19; CI: 0.08-0.45) and percentage of need for surgical intervention (OR 0.08; CI: 0.02-0.39) in the endoscopic drainage group were much lower than in the percutaneous drainage group. Total length of hospital stay (standard mean difference [SMD] -0.60; CI: -0.84 to -0.36) in the endoscopic drainage group was shorter; however, there was a nonsignificant difference in the length of post-procedure hospital stay (SMD: -0.30; CI: -1.05-0.44) between the two groups. CONCLUSION: endoscopic drainage is effective for PFCs, and superior in terms of lower reintervention and need for surgery rates over traditional percutaneous drainage, despite a similar clinical efficacy and safety compared with traditional percutaneous drainage.

[Interpretation of the international expert recommendations of clinical features to prompt referral for diagnostic assessment of cerebral palsy].

Under the guidance and support of national policies in recent years, the community medical system has been developed rapidly, among which primary child healthcare is carried out routinely in community hospitals, greatly alleviating the pressure of specialized pediatric hospitals and departments of pediatrics in secondary and tertiary general hospitals. However, due to the lack of professional training for primary child healthcare personnel in community medical institutions, early symptoms of children with cerebral palsy cannot be identified and so children with cerebral palsy are often unable to receive early diagnosis and intervention, which may affect their prognosis. An article about international expert consensus and recommendations on early identification and referral of cerebral palsy in community medical institutions was published in Development Medicine and Child Neurology in 2020. It proposed six clinical features that should prompt referral and two warning signs that warrant enhanced monitoring, as well as five recommendations for referral to medical experts and other healthcare professionals for the diagnosis of cerebral palsy. The recommendations may help primary child healthcare personnel in community medical institutions to early identify the children at high risk of cerebral palsy, thus reducing the delay of referral and intervention. This article gives an interpretation of the recommendations based on the actual situation in China, in order to improve the ability of primary child healthcare personnel in community medical institutions to early identify high-risk signals of cerebral palsy and conduct reasonable referral. This will help to achieve the early identification, early diagnosis, and early intervention to improve the prognosis of children with cerebral palsy.

Hard and soft tissue alterations during the healing stage of immediate implant placement and provisionalization with or without connective tissue graft: A randomized clinical trial.

AIMS: To evaluate the hard and soft tissue alterations of immediately placed and provisionalized implants with or without connective tissue graft (CTG). MATERIALS AND METHODS: Single unsalvageable maxillary incisors were replaced with immediately placed and provisionalized implants in 42 participants. The patients were randomly assigned to receive simultaneous CTG (test group) and not receive CTG (control group). Digital impression and cone-beam computed tomography images were obtained before extraction and after 6 months. Mid-facial gingival margin migrations, soft tissue contour changes and hard tissue remodelling were analysed and compared between the two groups using three-dimensional superimposition method. RESULTS: Forty participants completed the study. The test group showed significantly less buccal tissue collapse in the area 2-5 mm apical to the gingival margin. In both groups, the mid-facial gingival margin migrated in an apico-palatal direction and the socket void, except for a triangular space in the bucco-coronal region, demonstrated radiographic new bone formation without statistically significant differences. CONCLUSIONS: The CTG used with immediate implant placement and provisionalization could compensate for the facial tissue collapse, but it did not benefit maintenance of the mid-facial gingival margin position during the 6-month follow-up. New bone formation observed radiographically can be expected in most areas of the socket void, regardless of CTG use (ChiCTR-1900028494).

Tethered cord syndrome with lower back pain and lumbosacral angle increase: case report.

INTRODUCTION: Tethered cord syndrome (TCS) is the progressive development of various neuromuscular dysfunctions caused by the traction of the conus medullaris resulting from congenital or acquired causes, which are often accompanied by fecal and/or urinary incontinence and abnormal sensory motor functions of lower limbs. Lower back pain is a common clinical symptom of TCS patients and can be significantly improved by surgical untethering. However, the specific relationship between the increase in lumbosacral angle and TCS has rarely been reported. PATIENT: A case of TCS in an 8-year-old girl is reported. The patient had lower back pain complicated by increased lumbosacral angle for more than 20 days. DIAGNOSES: Physical examination and MRI results showed that the condition of the child has been complicated by TCS. INTERVENTIONS: After additional relevant examination, surgical untethering of the terminal filum was performed under general anesthesia. OUTCOMES: The symptoms of lower back pain disappeared, and the plain radiographs indicated that the lumbosacral angle decreased and lumbar lordosis returned to normal. During the follow-up period of half a year, the child did not experience particular discomfort or asymptomatic aggravation. CONCLUSIONS: For children with low back pain complicated by lumbosacral angle increase, MRI should be performed to exclude TCS. Once the patient has been diagnosed, early surgical treatment should be provided.

Does cognitive behavioral education reduce pain and improve joint function in patients after total knee arthroplasty? A randomized controlled trial.

INTRODUCTION: Cognitive behavioral therapy (CBT) is an effective treatment for reducing the pain of knee osteoarthritis (OA) and improving joint function. However, there are few studies on the effect of CBT on the pain severity after total knee arthroplasty (TKA). This study investigates the effectiveness of a CBT program on pain, knee function, quality of life, and pain catastrophizing in patients after TKA. METHODS: This was a randomized, parallel-group, controlled trial in which 100 patients with knee osteoarthritis (OA) prepared for TKA were randomly assigned to participate in CBT or usual care group. Evaluation outcomes include Visual Analogue Scale (VAS), Pain Catastrophizing Scale (PCS), Oxford Knee Score (OKS), Knee Range of Motion (ROM), EuroQol Five-Dimensional (EQ-5D), and Hospital for Special Surgery (HSS) Knee Rating Scale before and after surgery. RESULTS: We found that patients in the CBT group had a lower pain during activity from the fifth day (p = 0.003) to the third month (p = 0.019) after TKA. At the 12th month, the mean VAS score during activity in the CBT and usual care groups decreased from 4.5 to 0.8 and from 4.6 to 0.9, respectively, and there is no significant difference between the two groups. The PCS scores of patients in the CBT group were lower than those in the usual care group at 1st (p = 0.014) and 3rd months (p = 0.027) after surgery. No statistically significantly differences between the two groups in pain during rest, knee ROM, EQ-5D, OKS, and HSS. CONCLUSIONS: The CBT program was superior to usual care in reducing post-operative pain during activity from the fifth day to the third month and pain catastrophing in the first three months after TKA but has no statistically significantly differences in pain during rest, knee ROM, EQ-5D, OKS, and HSS. TRIAL REGISTRATION: Current Controlled Trials ChiCTR2000032857, date of registration: May, 14, 2020, retrospectively registered.

Demystifying, recognising and combating racism during the pandemic.

The increased reports of escalation of social inequalities, xenophobic and racist ideologies during the COVID-19 pandemic presents a growing concern. Nurses are not immune to xenophobia and racism, both as perpetrators and as victims. Although COVID-19 brings a new wave of xenophobia and racism, healthcare organisations have been tackling discriminatory and racist practices for decades. However, racist practice quite often goes undetected or unchallenged due to its associated sensitivity and a lack of understanding of its complexity. There is a need for a more open and non-judgemental discourse around interpretations of racism and its predisposing factors as a means of combating the growing reports. This discussion paper proposes a practice-orientated conceptualisation of racism and outlines some particular and sustainable areas for consideration for nurses to use in their daily practice. Developing self-awareness and nurturing the courage, confidence and commitment to challenge self and others is critical for transforming ethnocentric and racist ideologies.

Intrahepatic Cholangiocarcinoma Associated Paradoxical Peripheral Embolism and a Submassive Pulmonary Embolism.

Paradoxical peripheral embolism and submassive pulmonary embolism (PE), secondary to cancer-associated thrombosis, are yet to be reported in the literature. Here we describe a case presenting with an acute peripheral arterial embolism. Subsequent testing revealed a PE and an intrahepatic cholangiocarcinoma as the likely risk factors for thrombus, with arterial spread likely achieved through a patent foramen ovale. The patient's symptoms almost relieved upon catheter-directed thrombus fragmentation and aspiration, catheter-directed thrombolysis, and combined anticoagulation. Embolism and major bleeding did not occur during 6 months of follow-up under systemic anticoagulation with rivaroxaban. This case documents that catheter-directed thrombolysis and anticoagulation could be likely effective and safe in the treatment and prevention of recurrence of paradoxical embolism and PE secondary to cancer-associated thrombosis.
