Published: July 2022

Introduction HLX01 is the first rituximab biosimilar produced in China and the first monoclonal antibody biosimilar marketed in China. The purpose of this study was to comprehensively evaluate whether HLX01 is clinically consistent with the original drug based on real-world data to provide evidence for the clinical substitution of biosimilars in China. Methods A single-center retrospective study was conducted to select patients with diffuse large B-cell lymphoma who met the inclusion criteria and were treated with HLX01 or reference rituximab. Baseline characteristics, efficacy and safety results were recorded, and the corresponding statistical analysis was performed for various indicators. Results Thirty-three patients diagnosed with diffuse large B-cell lymphoma were included and divided into two groups that received HLX01 or reference rituximab. The results showed no significant difference in the overall response rate (86.7% vs. 88.9%; p = 1.000) or complete response rate (46.7% vs. 55.6%; p = 0.889) between the two groups. Kaplan–Meier survival curves also showed no significant difference in time-to-event variables between the two groups (log-rank = 0.244). Safety was also comparable in both groups. Conclusions HLX01 is a suitable replacement for reference rituximab in the treatment of diffuse large B-cell lymphoma and is relatively inexpensive, thereby reducing the economic burden of patients. Nevertheless, the conclusion of this study still needs to be further validated by large-sample real-world data and explored for HLX01 in other indications, such as follicular lymphoma. Clinical trial registration Not applicable.

Objective The barriers to delivering clinical non-communicable disease services in low- and middle-income countries have risen with the onset of COVID-19. Using Ghana as a case study, this article examines the changes COVID-19 has brought to diabetes service delivery and considers policy responses to deal with future such outbreaks. Methods We conducted 18 interviews between November 2020 and February 2021 with health professionals and administrators from primary, secondary and tertiary facilities within the Ghana Health Service. The analysis was performed using deductive and inductive methods. Results There were six general themes in interviewees’ responses: (1) COVID-19 had exacerbated the problems of high medicine and service costs and medicine shortages, (2) the pandemic had exacerbated problems of poor patient record keeping, (3) COVID-19 had reduced the availability of suitably trained health providers, (4) staff had become demoralized by management’s unwillingness to make innovative changes to cope with the pandemic, (5) COVID-19 led to a reorganization of diabetes services, and (6) the country’s national health insurance scheme lacked flexibility in dealing with the pandemic. Conclusions Access to resources is limited in LMICs. However, our study highlights practical policy responses that can improve health providers’ response to COVID-19 and future pandemics.
How COVID-19 is (and is not) changing the way we talk about sex and dating: A critical analysis of sex advice during the pandemic
Authors: Hindes Sophie , Urry Kristi 
Published: July 2022

In this article, we applied a ‘sex critical’ lens to discursively analyse online sex advice available to Australian readers in the first 3 months of ‘lockdown’ during the COVID-19 pandemic (March–June 2020). We explored how sex and intimacy were being talked about within the pandemic context, examining if and how this was different to pre-pandemic sex advice. We found both the perpetuation of dominant discourses that limit understandings of sex and sexual practices, and challenges to these which open exciting possibilities for new sexual intimacies.

Purpose: To investigate the safety and efficacy of fast-track management of concurrent percutaneous coronary intervention (PCI) in patients with abdominal aortic aneurysm scheduled for endovascular aortic aneurysm repair (EVAR). Materials and Methods: Eligible patients with abdominal aortic aneurysm who received EVAR from January 2011 to December 2019 were included in this retrospective cohort study. Propensity score (PS)–matched analysis was used to balance the baseline between the fast-track and standard control (EVAR without significant coronary artery disease) groups. Effects of fast-track management on short-term and midterm outcomes were evaluated via Cox proportional hazard regression and logistic regression analyses with corresponding hazard ratio (HR) or odds ratio (OR) and associated 95% confidence intervals (95% CIs), respectively. Results: The study included 669 patients (73 fast-track and 596 standard control). Compared with the standard control group, no significant difference was found regarding major adverse cardiac events (HR 0.78, 95% CI [0.36, 1.68], p=0.519), overall mortality (HR 0.63, 95% CI [0.25, 1.55], p=0.315), and 30-day major hemorrhage events (OR 1.01, 95% CI [0.99, 1.03], p=0.514). The results were consistent in the PS-matched cohorts regarding major adverse cardiac events (HR 0.57, 95% CI [0.25, 1.29], p=0.176), overall mortality (HR 0.43, 95% CI [0.17, 1.11], p=0.820), and 30-day major hemorrhage events (OR 1.00, 95% CI [0.05, 10.61], p=0.999). Similar results were found in the subgroup analyses concerning fast-track management of 2-week intervals and patients with high age-adjusted Charlson comorbidity index. Conclusions: Under appropriate perioperative care, shortening the time interval between PCI and EVAR to 1 month, or even 2 weeks, seemed to be safe and effective. Short-term and midterm cardiovascular and survival outcomes were comparable with patients who underwent standard EVAR without significant coronary artery disease.

Objective To report our initial clinical experience with N-hexyl cyanoacrylate (NHCA), a novel liquid agent for neurovascular embolization. Methods Four paragangliomas were treated with percutaneous embolization using NHCA as the sole embolic material. In one dural arteriovenous fistula (dAVF), NHCA was used in combination with other embolic materials. Procedural specifics, complications and angiographic results were retrospectively evaluated. Results Total or subtotal devascularization was obtained in 3 of the 4 paragangliomas. In the largest tumor, only partial devascularization could be achieved. The dAVF was completely occluded. Catheter entrapment did not occur. After dAVF treatment, the patient had an asymptomatic lacunar infarction, while there was no procedural morbidity related to paraganglioma treatment. Conclusions In this series, neurovascular embolization with NHCA was feasible and effective. It may be particularly beneficial for small and tortuous vessels that require low-profile catheterization and a slow and controlled polymerization. Further studies are necessary to prove the benefits of NHCA over established embolic agents.

Published: July 2022

Objectives The Ponseti method has led to vast improvements in outcomes for infants born with clubfoot deformity, but challenges with compliance during the bracing phase of the protocol remain. Unilateral braces promise higher compliance but often have led to unacceptably high recurrence. Methods We have developed a novel unilateral brace for clubfoot deformity that strategically applies patient-specific, anatomically-targeted forces to the lower limb to maintain correction. We retrospectively reviewed the cases of 26 patients with minimum follow-up of 24 months. The data were analyzed for recurrence rates, caregiver-reported compliance, and differences in Pirani score, dorsiflexion, abduction, hindfoot eversion, and resting rotation between initial and final follow-up. Results Most patients ( N = 23, 88%) were compliant with the bracing protocol. Two patients showed recurrence of deformity (8%). There were statistically significant improvements in Pirani score, dorsiflexion, abduction, hindfoot eversion, and resting external rotation. A subset of patients with sub-optimal correction at baseline showed improvement in all parameters across the course of bracing. Conclusions This novel unilateral brace for maintenance of clubfoot correction after Ponseti treatment demonstrates rates of recurrence rates and caregiver-reported compliance at 2 years of follow up that are comparable to outcomes with traditional bilateral foot abduction orthoses.

Abstract
Background
Symptom Screening in Pediatrics Tool (SSPedi) was developed for symptom screening by children 8-18 years. Objectives were to evaluate the reliability and validity of proxy-SSPedi and self-report mini-SSPedi for younger children.

Methods
This multi-center study enrolled guardians of children 2-7 years receiving cancer treatments (proxy-SSPedi) and their children 4-7 years (mini-SSPedi). The two populations were: (1) More symptomatic group where children were receiving active cancer treatment and were in hospital or clinic for four consecutive days; and (2) Less symptomatic group where children were receiving maintenance therapy for acute lymphoblastic leukemia or had completed cancer therapy. Proxy-SSPedi or mini-SSPedi were completed with measures of mucositis, nausea, pain, quality of life and overall symptoms. Respondents in the more symptomatic group repeated proxy-SSPedi/mini-SSPedi and a global symptom change scale 3 days later.

Results
There were 402 guardians and 326 children included in the analysis. Test re-test reliability of proxy-SSPedi showed intraclass correlation coefficient (ICC) 0.83 (95% confidence interval (CI) 0.72-0.90). Mean difference in proxy-SSPedi between more and less symptomatic groups was 9.7 (95% CI 8.3-11.1). Proxy-SSPedi was responsive to change and hypothesized relationships between measures were observed. With a priori threshold ≥0.6, inter-rater ICC among all dyads and those 6-7 years were 0.54 (95% CI 0.45-0.62) and 0.62 (95% CI 0.50-0.71) respectively. Among participating children, other hypothesized reliability and validity thresholds were generally met.

Conclusions
Proxy-SSPedi is reliable, valid and responsive in children 2-7 years old receiving cancer treatments. Mini-SSPedi can be used for children 6-7 years of age.

Abstract
Background
Osteosarcoma (OS) is the most common primary malignant bone tumors in children and adolescents. Large numbers of studies have focused on the long non-coding RNA (lncRNA) that plays essential roles in the progression of osteosarcoma. Nevertheless, the functions and underlying mechanisms of LncRNA NDRG1 in osteosarcoma remain unknown.

Methods
Differentially expressed lncRNAs between osteosarcoma and adjacent normal tissues were identified through RNA sequencing. The role of LncRNA NDRG1 in osteosarcoma proliferation and metastasis were investigated through in vitro and in vivo functional experiments. The interaction between LncRNA NDRG1 and miR-96-5p was verified through bioinformatic analysis and luciferase reporter assay. Regulation relationship between LncRNA NDRG1 and miR-96-5p was further evaluated by the rescue experiments. Additionally, the changes in the expression of epithelial-mesenchymal transition (EMT) and the PI3K/AKT pathway were verified by Western blot.

Results
LncRNA NDRG1 was up-regulated in osteosarcoma cell lines and tissues and the expression of LncRNA NDRG1 was correlated with the overall survival of osteosarcoma patients. Functional experiments exhibited that LncRNA NDRG1 aggravated osteosarcoma proliferation and migration in vitro; meanwhile, animals experiments showed that LncRNA NDRG1 promoted osteosarcoma growth and metastasis in vivo. Mechanistically, LncRNA NDRG1 was found to aggravate osteosarcoma progression and regulate the PI3K/AKT pathway by sponging miR-96-5p.

Conclusions
LncRNA NDRG1 aggravates osteosarcoma progression and regulates the PI3K/AKT pathway by sponging miR-96-5p. Therefore, LncRNA NDRG1 could act as a prognostic marker and a therapeutic target for osteosarcoma in the future.

Authors: Wu Xue-qin , Li Jing-yi , Du Wen-jing 
Published: July 2022

Abstract
Purpose
To examine the distribution of causes of death (CODs) in patients with small cell lung cancer (SCLC).

Methods
Patients diagnosed with SCLC were identified from the Surveillance, Epidemiology, and End Results Program database during 2004–2015. Standardized mortality rates (SMRs) were performed for each COD to present changes in risk for a particular COD following SCLC diagnosis.

Results
A total of 44,506 patients diagnosed with SCLC were identified in this study, and 42,476 patients died during the follow-up. Of total deaths, 69.5% occurred within the first years after diagnosis, 26% occurred from 1 to 3 years, and 4.5% individuals survived longer than 3 years. In addition, 88.7% of deaths were caused by SCLC, followed by non-cancer causes (7.1%) and other cancers (4.2%). Moreover, non-cancer CODs increased from 6.3 to 30% over time after 3 years of diagnosis. As for non-cancer CODs, cardiovascular diseases, COPD, and septicemia were the most common in SCLC.

Conclusion
Non-cancer CODs, such as cardiovascular events, COPD and septicemia, contribute to a considerable proportion of deaths among long-term SCLC survivors, supporting the involvement of multidisciplinary care for the follow-up strategy in SCLC.

Authors: Yeh Kuang-Ting , Wu Wen-Tien , Wang Jen-Hung , Shih Jui-Tien 
Published: July 2022

Abstract
Background
Foveal tears of the traumatic triangular fibrocartilage complex (TFCC) are the most commonly neglected high-energy injuries of the wrist joint, and the patients with such tears often experience unrecovered ulnar-sided wrist pain and poor wrist function. This study investigated the functional outcomes of patients who underwent arthroscopic repair of foveal TFCC tears with suture anchors and adjuvant platelet-rich plasma (PRP) injections after the surgery.

Methods
From September 2014 to August 2018, 156 men and 45 women with diagnoses of foveal TFCC tears without wrist fractures underwent arthroscopic repair by using the outside-in method with 1.3-mm suture anchors and subsequent PRP injection. After surgery, splinting was applied for 6 weeks, and the patients underwent rehabilitation, re-examination, and follow-up at our clinic. The patients’ wrist functional scores and grip strength data were retrospectively collected.

Results
The mean follow-up period was 32.6 months, and the mean age was 26.7 years. The mean modified Mayo wrist score improved from 48.5 ± 2.6 to 82.4 ± 2.5, whereas the mean Disabilities of the Arm, Shoulder and Hand (DASH) score decreased from 39.2 ± 6.7 to 10.6 ± 7.5. Overall, the wrist functions of 186 (92.5%) of the patients were satisfactory according to their modified Mayo wrist scores, and the patients with satisfactory scores returned to sports or work activities. These patients retained normal ranges of motion, and their average grip strength in the affected hand was restored to at least 85% of that of the other hand.

Conclusions
According to the postoperative 25–36 months surgical results of our study, arthroscopic repair with adjuvant PRP injections is a satisfactory method of repairing early foveal tears of the TFCC and can enhance wrist function by relieving pain and increasing tolerance for work or sports.

Published: July 2022

Abstract
Background
Distal common bile duct (dCBD) cancer is typical indication for pancreaticoduodenectomy (PD). We aimed to retrospectively evaluate surgical outcomes and investigate prognostic factors of dCBD adenocarcinoma for which PD was performed at a single institution.

Methods
We searched consecutive cases of dCBD adenocarcinoma undergone PD at Samsung Medical Center from 1995 to 2018. Cases with distant metastasis or palliative intent were excluded. The year in which the survival rate was dramatically improved was identified and entire years were divided into two periods for comparison. To balance between the two periods, we conducted propensity score matching (PSM) analysis using age, sex, body mass index (BMI), and American Society of Anesthesiologist score.

Results
Total of 804 cases were enrolled in this study. The entire period was divided into early period of 18 years and recent period of 6 years. The early and late period included 466 and 338 patients, respectively. As a result of PSM, balanced 316 patients were selected from each of the two periods. Significant improvements in surgical outcomes were identified, including shorter operation time, fewer blood loss, shorter hospitalization, and favorable overall survival. As results of multivariable analysis of independent risk factors for overall survival, older age and advanced N stage were identified, as expected. It was distinct that aggressive surgery and advanced tumor state in the early period and a lower BMI in the late period negatively affected the survival, respectively.

Conclusions
Surgical outcomes of dCBD cancer underwent PD was improved. There were few modifiable factors to improve survival and continuous further study is needed to detect dCBD cancer in the early stages.

Published: July 2022

Abstract
Background
Existing approaches for treating elbow fractures include lateral, medial, anterior and posterior approaches, though the anterior approach is often not chosen by surgeons to avoid damage to important nerves and blood vessels. However, the anterior approach has unique advantages. The purpose of this study was to report outcomes of 38 patients with coronal plane elbow fractures treated through the anterior approach.

Methods
We retrospectively analyzed 38 cases of coronal plane elbow fracture treated through an anterior approach at our institution between March 2015 and July 2019. The length of the surgical incision, operation time, and postoperative complications were recorded. The range of flexion, extension, and rotation of the affected elbow and the healthy elbow were collected at follow-up. Functional outcomes were evaluated using the Mayo Elbow Function Score (MEPS).

Results
All 38 patients were followed up for a mean of 21.26 months (range 12–36 months). Intraoperatively, the mean surgical incision length was 8 ± 2 cm and the mean operative time was 123 ± 59 min. At the final follow-up, solid osseous union was confirmed for all coronal plane elbow fractures. The mean elbow flexion arc was 129 ± 7°, and the extension arc was 9 ± 6°. The mean pronation arc was 83 ± 3°, and the supination arc was 80 ± 3°. The mean MEPS was 90 ± 8 points, with 18 excellent cases and 20 cases of excellent and good results, respectively. In 31 cases, there was no significant difference in elbow extension, flexion, or pronation between the single-fracture and healthy elbows (P > 0.05), though the arc of supination was slightly worse than that of the healthy elbow (P < 0.05). VAS pain scores before the operation, at three months after the operation, and during follow-up were compared, and pain was significantly reduced after treatment (P < 0.05). Two patients experienced transient postoperative median nerve paralysis, from which they recovered within three months. One patient had mild heterotopic ossification and was not treated because it did not affect the function of the elbow joint. All patients returned to work and were satisfied with the treatment.

Conclusion
The anterior approach has the benefits of simplicity, safety, minimal invasiveness, excellent exposure, and satisfactory prognosis for coronal plane elbow fracture.
