[Clinical efficacy of induction chemoimmunotherapy for locally advanced hypopharyngeal carcinoma: a prospective phase Ⅱ study]

Objective: To evaluate the objective response rate (ORR) of induction chemoimmunotherapy with camrelizumab plus TPF (docetaxel, cisplatin, and capecitabine) for locally advanced hypopharyngeal squamous cell carcinoma (LA HSCC) and potential predictive factors for ORR. Methods: A single-center, prospective, phase 2 and single-arm trial was conducted for evaluating antitumor activity of camrelizumab+TPF(docetaxel+cisplatin+capecitabine) for LA HSCC between May 21, 2021 and April 15, 2023, patients admitted to the Eye & ENT Hospital affiliated with Fudan University. The primary endpoint was ORR, and enrolled patients with LA HSCC at T3-4N0-3M0 received induction chemoimmunotherapy for three cycles: camrelizumab 200 mg day 1, docetaxel 75 mg/m2 day 1, cisplatin 25 mg/m2 days 1-3, and capecitabine 800 mg/m2 days 1-14. Patients were assigned to radioimmunotherapy when they had complete response or partial response (PR)>70% (Group A), or assigned to surgery plus adjuvant radiotherapy/chemoradiotherapy when they had PR≤70% (Group B), and the responses were defined by using tumor volume evaluation system. Tumor diameter was also used to assess the treatment responses by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Use SPSS 23.0 software was used to analyze the data. Results: A total of 51 patients were enrolled who underwent the induced chemoimmunotherapy for three cycles, and all were males, aged 35-69 years old. After three cycles of induction immunochemotherapy, 42 (82.4%) patients existed in Group A (complete response or PR>70%) and 9 patients (17.6%) in Group B (PR≤70%), the ORR was 82.4%. The primary endpoint achieved expected main research objectives. Compared to the patients of Group A, the patients of Group B showed the higher T stage and the larger volume of primary tumor before induced immunochemotherapy, and also had the less regression of tumor volume after induced immunochemotherapy (all P<0.05). The optimal cutoff value of pre-treatment tumor volume for predicting ORR was 39 cm3. The T stage (OR=12.71, 95%CI: 1.4-112.5, P=0.022) and the volume (OR=7.1, 95%CI: 1.4-36.8, P=0.018) of primary tumor were the two main factors affecting ORR rate of induction chemoimmunotherapy. Conclusion: The induction chemoimmunotherapy with camrelizumab plus TPF shows an encouraging antitumor efficacy in LA HSCC.

A qualitative interview study exploring the psychological health impacts of the SPIN-CHAT program among people with systemic sclerosis at the onset of COVID-19: perceptions of trial participants and research team members

PURPOSE

Explore trial participants' and research team members' perceptions of the impact of the videoconference-based, supportive care program (SPIN-CHAT Program) during early COVID-19 for individuals with systemic sclerosis (SSc).

METHODS

Data were collected cross-sectionally. A social constructivist paradigm was adopted, and one-on-one videoconference-based, semi-structured interviews were conducted with SPIN-CHAT Trial participants and research team members. A hybrid inductive-deductive approach and reflexive thematic analysis were used.

RESULTS

Of the 40 SPIN-CHAT Trial participants and 28 research team members approached, 30 trial participants (Mean age = 54.9; SD = 13.0 years) and 22 research team members agreed to participate. Those who took part in interviews had similar characteristics to those who declined. Five themes were identified: (1) The SPIN-CHAT Program conferred a range of positive psychological health outcomes, (2) People who don't have SSc don't get it: The importance of SSc-specific programming, (3) The group-based format of the SPIN-CHAT Program created a safe space to connect and meet similar others, (4) The structure and schedule of the SPIN-CHAT Program reduced feelings of boredom and contributed to enhanced psychological health, (5) The necessity of knowledge, skills, and tools to self-manage SSc and navigate COVID-19.

CONCLUSION

Participants' and research team members' perspectives elucidated SPIN-CHAT Program benefits and how these benefits may have been realized. Results underscore the importance of social support from similar others, structure, and self-management to enhance psychological health during COVID-19.

Surgical treatment of nasopharyngeal cancer - a consensus recommendation from two Chinese associations

BACKGROUND

Surgical treatment is playing an increasingly important role in the management of nasopharyngeal carcinoma (NPC). This consensus focuses on the indications for optimal surgery, and surgical methods in the whole process of treatment for NPC to provide a useful reference to assist these difficult clinical decisions.

METHODOLOGY

A thorough review of available literature on NPC and surgery was conducted by the Association for the prevention and treatment of nasopharyngeal carcinoma in China, international exchange and promotion Association for medicine and healthcare, and the Committee on nasopharyngeal cancer of Guangdong provincial anticancer association. A set of questions and a preliminary draft guideline was circulated to a panel of 1096 experienced specialists on this disease for voting on controversial areas and comments. A refined second proposal, based on a summary of the initial voting and different opinions expressed, was recirculated to the experts in two authoritative medical science and technology academic groups in the prevention and treatment of NPC in China for review and reconsideration.

RESULTS

The initial round of questions showed variations in clinical practice even among similar specialists, reflecting the lack of high-quality supporting data and resulting difficulties in formulating clinical decisions. Through exchange of comments and iterative revisions, recommendations with high-to-moderate agreement were formulated on general treatment strategies and details of surgery, including indications and surgical approaches.

CONCLUSION

By standardizing the surgical indications and practice, we hope not only to improve the surgical outcomes, but also to highlight the key directions of future clinical research in the surgical management of NPC.

[Comparison of quality-of-life after proximal gastrectomy with double tract reconstruction versus gastric tube reconstruction in patients with proximal gastric cancer]

Objective: To compare the surgical safety and postoperative quality of life between proximal gastrectomy with double tract reconstruction (PG-DT) and proximal gastrectomy with gastric tube reconstruction (PG-GT) for proximal gastric cancer. Methods: This was a retrospective cohort study of clinical and follow-up data of 99 patients with proximal gastric cancer who had undergone double tract or gastric tube surgery in Nanjing Drum Tower Hospital from January 2016 to September 2021. We allocated them to two groups according to surgical procedure, namely a double tract group (PG-DT, 50 patients) and gastric tube group (PG-GT, 49 patients). Proximal gastrectomy with double tract reconstruction entails constructing a Roux-en-Y esophagojejunostomy after severing the proximal stomach, and then constructing a side-to-side anastomosis between the residual stomach and the jejunum to establish an anti-reflux barrier and thus minimize postoperative gastroesophageal reflux. Proximal gastrectomy with gastric tube reconstruction entails severing the proximal gastric stomach, constructing a tubular shaped gastric remnant, and then using a linear stapler to directly anastomose the posterior wall of the esophagus to the anterior wall of the resultant gastric tube. The primary end point was the quality of life of the two groups 1 year postoperatively (post-gastrectomy syndrome assessment scale: the higher the scores for change in body mass, food intake per meal, meal quality subscale, total physical health measurement, and total mental health measurement, the better the quality-of-life, and the higher the scores for other indicators, the worse the quality-of-life). The secondary end points were intraoperative and postoperative status, changes in nutritional status 1, 3, 6, and 12 months postoperatively, and long-term postoperative complications (gastroesophageal reflux, anastomotic stenosis, intestinal obstruction, and gastric emptying disorder 1 year postoperatively). Results: In the PG-DT group, there were 35 (70%) men and 15 (30%) women, 33 (66.0%) patients were aged <65 years, and 37 (74.0%) of them had a body mass index of 18-25 kg/m2; whereas in the PG-GT group, there were 41 (83.7%) men and eight (16.3%) women, 21 (42.9%) patients aged <65 years, and 34 (69.4%) patients with a body mass index of 18-25 kg/m2. There were no significant differences in baseline data between the two groups except for age (P=0.021). There were no significant differences in intraoperative blood loss, number of lymph node dissected, length of hospital stay, and incidence of perioperative complications between the two groups (all P>0.05). Compared with the PG-GT group, the incidence and severity of postoperative reflux esophagitis were significantly lower in the PG-DT group (4.0% [2/50] vs. 26.5% [13/49], χ2=13.507, P=0.009). The incidences of postoperative anastomotic stenosis, intestinal obstruction, and gastric retention did not differ significantly between the two groups (all P>0.05). Patients in the PG-DT group had better quality-of-life scores for esophageal reflux (2.8 [2.3,4.0] vs. 4.8 [3.8,5.0], Z=3.489, P<0.001), eating discomfort (2.7 [1.7,3.0] vs. 3.3 [2.7,4.0 ], Z=3.393, P=0.001), and total symptoms (2.3 [1.7,2.7] vs. 2.5 [2.2,2.9], Z=2.243, P=0.025) than those in the gastric tube group; The scores for postoperative symptoms (2.0 [1.0,3.0] vs. 2.0 [2.0, 3.0], Z=2.127, P=0.033), meals consumed (2.0 [1.0, 2.0] vs. 2.0 [2.0, 3.0], Z=3.976, P<0.001), work (1.0 [1.0, 2.0] vs. 2.0 [1.0, 2.0], Z=2.279, P=0.023] and daily life (1.7 [1.3, 2.0] vs. 2.0 [2.0, 2.3], Z=3.950, P<0.001) were better in the PG-DT than the PG-GT group. Patients in the PG-GT group scored better than those in the PG-DT group for somatic symptoms, such as anal evacuation (3.0 [2.0, 4.0] vs. 3.5 [2.0, 5.0], Z=2.345, P=0.019). There were no significant differences in hemoglobin, serum albumin, serum total protein, or weight loss 1 year postoperatively between the two groups (all P>0.05). Conclusions: The safety of double tract anastomosis for proximal gastric cancer is comparable to that of gastric tube surgery. Compared with gastric tube surgery, double tract anastomosis achieves less esophageal reflux and better quality of life, making it a preferable surgical procedure for proximal gastric cancer.

Comparison of Wired and Wireless Heart Rate Monitoring in the Neonatal Intensive Care Unit

In the Neonatal Intensive Care Unit (NICU), infants' vital signs are monitored on a continuous basis via wired devices. These often interfere with patient care and pose increased risks of skin damage, infection, and tangling around the body. Recently, a wireless system for neonatal monitoring called ANNEⓇ One (Sibel Health, Chicago, USA) was developed. We designed an ongoing study to evaluate the feasibility, reliability and accuracy, of using this system in the NICU. Vital signals were simultaneously acquired by using the standard, wired clinical monitor and the ANNEⓇ device. Data from 10 NICU infants were recorded for 8 hours per day during 4 consecutive days. Initial analysis of the heart rate (HR) data revealed four problems in comparing the signals: 1) gaps in the signals - periods of time for which data were unavailable, 2) wired and wireless signals were sampled at different rates, 3) a delay between the sampled values of wired and wireless signals, and 4) this delay increased with time. To address these problems, we developed a pre-processing algorithm that interpolated samples in short gaps, resampled the signals to an equal rate, estimated the delay and drift rate between corresponding signals, and aligned the signals. Applications of the pre-processing algorithm to 40 recordings demonstrated that it was very effective. A strong agreement between wireless and wired HR signals was seen, with an average correlation of 0.95±0.04, a slope of 1.00, and a variance accounted for 89.56±7.62%. Bland-Altman analysis showed a low bias across the ensemble, with an average difference of 0.11 (95% confidence interval of -0.02 to 0.24) bpm.Clinical relevance- This algorithm provides the means for a detailed comparison of wired and wireless monitors in the NICU.

Exploring research team members' and trial participants' perceptions of acceptability and implementation within one videoconference-based supportive care program for individuals affected by systemic sclerosis during COVID-19: a qualitative interview study

The SPIN-CHAT Program was designed to support mental health among individuals with systemic sclerosis (SSc; commonly known as scleroderma) and at least mild anxiety symptoms at the onset of COVID-19. The program was formally evaluated in the SPIN-CHAT Trial. Little is known about program and trial acceptability, and factors impacting implementation from the perspectives of research team members and trial participants. Thus, the propose of this follow-up study was to explore research team members' and trial participants' experiences with the program and trial to identify factors impacting acceptability and successful implementation. Data were collected cross-sectionally through one-on-one, videoconference-based, semi-structured interviews with 22 research team members and 30 purposefully recruited trial participants (Mage = 54.9, SD = 13.0 years). A social constructivist paradigm was adopted, and data were analyzed thematically. Data were organized into seven themes: (i) getting started: the importance of prolonged engagement and exceeding expectations; (ii) designing the program and trial: including multiple features; (iii) training: research team members are critical to positive program and trial experiences; (iv) offering the program and trial: it needs to be flexible and patient-oriented; (v) maximizing engagement: navigating and managing group dynamics; (vi) delivering a videoconference-based supportive care intervention: necessary, appreciated, and associated with some barriers; and (vii) refining the program and trial: considering modification when offered beyond the period of COVID-19 restrictions. Trial participants were satisfied with and found the SPIN-CHAT Program and Trial to be acceptable. Results offer implementation data that can guide the design, development, and refinement of other supportive care programs seeking to promote psychological health during and beyond COVID-19.

The use of wireless sensors in the neonatal intensive care unit: a study protocol

Background

Continuous monitoring of vital signs and other biological signals in the Neonatal Intensive Care Unit (NICU) requires sensors connected to the bedside monitors by wires and cables. This monitoring system presents challenges such as risks for skin damage or infection, possibility of tangling around the patient body, or damage of the wires, which may complicate routine care. Furthermore, the presence of cables and wires can act as a barrier for parent-infant interactions and skin to skin contact. This study will investigate the use of a new wireless sensor for routine vital monitoring in the NICU.

Methods

Forty-eight neonates will be recruited from the Montreal Children's Hospital NICU. The primary outcome is to evaluate the feasibility, safety, and accuracy of a wireless monitoring technology called ANNE^® One (Sibel Health, Niles, MI, USA). The study will be conducted in 2 phases where physiological signals will be acquired from the standard monitoring system and the new wireless monitoring system simultaneously. In phase 1, participants will be monitored for 8 h, on four consecutive days, and the following signals will be obtained: heart rate, respiratory rate, oxygen saturation and skin temperature. In phase 2, the same signals will be recorded, but for a period of 96 consecutive hours. Safety and feasibility of the wireless devices will be assessed. Analyses of device accuracy and performance will be accomplished offline by the biomedical engineering team.

Conclusion

This study will evaluate feasibility, safety, and accuracy of a new wireless monitoring technology in neonates treated in the NICU.

[Correlation between pelvic relapses of rectal cancer after radical and R0 resection: A regression model-based analysis]

Objective: To propose a new staging system for presacral recurrence of rectal cancer and explore the factors influencing radical resection of such recurrences based on this staging system. Methods: In this retrospective observational study, clinical data of 51 patients with presacral recurrence of rectal cancer who had undergone surgical treatment in the Department of Gastrointestinal Surgery, Peking University People's Hospital between January 2008 and September 2022 were collected. Inclusion criteria were as follows: (1) primary rectal cancer without distant metastasis that had been radically resected; (2) pre-sacral recurrence of rectal cancer confirmed by multi-disciplinary team assessment based on CT, MRI, positron emission tomography, physical examination, surgical exploration, and pathological examination of biopsy tissue in some cases; and (3) complete inpatient, outpatient and follow-up data. The patients were allocated to radical resection and non-radical resection groups according to postoperative pathological findings. The study included: (1) classification of pre-sacral recurrence of rectal cancer according to its anatomical characteristics as follows: Type I: no involvement of the sacrum; Type II: involvement of the low sacrum, but no other sites; Type III: involvement of the high sacrum, but no other sites; and Type IV: involvement of the sacrum and other sites. (2) Assessment of postoperative presacral recurrence, overall survival from surgery to recurrence, and duration of disease-free survival. (3) Analysis of factors affecting radical resection of pre-sacral recurrence of rectal cancer. Non-normally distributed measures are expressed as median (range). The Mann-Whitney U test was used for comparison between groups. Results: The median follow-up was 25 (2-96) months with a 100% follow-up rate. The rate of metachronic distant metastasis was significantly lower in the radical resection than in the non-radical resection group (24.1% [7/29] vs. 54.5% [12/22], χ²=8.333, P=0.026). Postoperative disease-free survival was longer in the radical resection group (32.7 months [3.0-63.0] vs. 16.1 [1.0-41.0], Z=8.907, P=0.005). Overall survival was longer in the radical resection group (39.2 [3.0-66.0] months vs. 28.1 [1.0-52.0] months, Z=1.042, P=0.354). According to univariate analysis, age, sex, distance between the tumor and anal verge, primary tumor pT stage, and primary tumor grading were not associated with achieving R0 resection of presacral recurrences of rectal cancer (all P>0.05), whereas primary tumor pN stage, anatomic staging of presacral recurrence, and procedure for managing presacral recurrence were associated with rate of R0 resection (all P<0.05). According to multifactorial analysis, the pathological stage of the primary tumor pN1-2 (OR=3.506, 95% CI: 1.089-11.291, P=0.035), type of procedure (transabdominal resection: OR=29.250, 95% CI: 2.789 - 306.811, P=0.005; combined abdominal perineal resection: OR=26.000, 95% CI: 2.219-304.702, P=0.009), and anatomical stage of presacral recurrence (Type III: OR=16.000, 95% CI: 1.542 - 166.305, P = 0.020; type IV: OR= 36.667, 95% CI: 3.261 - 412.258, P = 0.004) were all independent risk factors for achieving radical resection of anterior sacral recurrence after rectal cancer surgery. Conclusion: Stage of presacral recurrences of rectal cancer is an independent predictor of achieving R0 resection. It is possible to predict whether radical resection can be achieved on the basis of the patient's medical history.

HISMD: A Novel Immune Subtyping System for HNSCC

Immune subtyping is an important way to reveal immune heterogeneity, which may contribute to the diversity of the progression and treatment in head and neck squamous cell carcinoma (HNSCC). However, reported immune subtypes mainly focus on levels of immune infiltration and are mostly based on a mono-omics profile. This study aimed to identify a comprehensive immune subtype for HNSCC via multi-omics clustering and build a novel subtype prediction system for clinical application. Data were obtained from The Cancer Genome Atlas database and our independent multicenter cohort. Multi-omics clustering was performed to identify 3 clusters of 499 patients in The Cancer Genome Atlas based on immune-related gene expression and somatic mutations. The immune characteristics and biological features of the obtained clusters were revealed by bioinformatics, and 3 immune subtypes were identified: 1) adaptive immune activation subtype predominantly enriched in T cells, 2) innate immune activation subtype predominantly enriched in macrophages, and 3) immune desert subtype. Subsequently, the clinical implications of each subtype were analyzed per clinical epidemiology. We found that adaptive immune activation showed better survival outcomes and had a similar response to chemotherapy with innate immune activation, whereas immune desert might be relatively resistant to chemotherapy. Moreover, a subtype prediction system was developed by deep learning with whole slide images and named HISMD: HNSCC Immune Subtypes via Multi-omics and Deep Learning. We endowed HISMD with interpretability through image-based key feature extraction. The clinical implications, biological significances, and predictive stability of HISMD were successfully verified by using our independent multicenter cohort data set. In summary, this study revealed the immune heterogeneity of HNSCC and obtained a novel, highly accurate, and interpretable immune subtyping prediction system. For clinical implementation in the future, additional validation and utility studies are warranted.

[Indications and complications prevention and management of phaseⅡ implantation of Provox Vega voice prosthesis after total laryngectomy]

Objective: To explore the indications and management of common postoperative complications of phase II tracheoesophageal puncture (TEP) for Provox Vega voice prosthesis after total laryngectomy. Methods: The clinical data of 20 patients undergoing phase II TEP for Provox Vega voice prosthesis in our hospital between May 2021 and January 2022 were analyzed. Among them, there were 19 males and 1 female, aged from 37 to 76 years, with an average age of (60.0±8.4)years. The surgical indications and the prevention and treatment of common postoperative complications were summarized. Descriptive analysis was used in this research. Results: The basic surgical indications were as following: after total laryngectomy, there was no stenosis of the stoma and esophagus entrance, no scar constitution, no mouth opening restriction, no stiffness and backward restraint of the neck after radiotherapy, and more than half a year apart surgery or radiotherapy. Among the 20 patients, 18 underwent implantation successfuly, 1 failed in the operation, and for 1 patient, the prosthesis was removed due to bleeding 1 week after implantation. The common postoperative complications included TEP fistula infection (2 cases), the TEP fistula bleeding(1 case), deep neck (prevertebral) abscess (1 case), granulation at the inner side of the TEP fistula (1 case), invagination of the prosthesis (2 cases) and leakage around the prosthesis (2 cases). All patients were cured with different interventions. Conclusions: The Provox Vega voice prosthesis is generally safe for phase Ⅱ implantatione, but implantation indications need to be established. Common postoperative complications can be solved through preventive and remedial interventions.

Randomized controlled trial of an internet-based self-guided hand exercise program to improve hand function in people with systemic sclerosis: the Scleroderma Patient-centered Intervention Network Hand Exercise Program (SPIN-HAND) trial

BACKGROUND

Systemic sclerosis (scleroderma; SSc) is a rare autoimmune connective tissue disease. Functional impairment of hands is common. The Scleroderma Patient-centered Intervention Network (SPIN)-HAND trial compared effects of offering access to an online self-guided hand exercise program to usual care on hand function (primary) and functional health outcomes (secondary) in people with SSc with at least mild hand function limitations.

METHODS

The pragmatic, two-arm, parallel-group cohort multiple randomized controlled trial was embedded in the SPIN Cohort. Cohort participants with Cochin Hand Function Scale (CHFS) scores ≥ 3 and who indicated interest in using the SPIN-HAND Program were randomized (3:2 ratio) to an offer of program access or to usual care (targeted N = 586). The SPIN-HAND program consists of 4 modules that address (1) thumb flexibility and strength; (2) finger bending; (3) finger extension; and (4) wrist flexibility and strength. The primary outcome analysis compared CHFS scores 3 months post-randomization between participants offered versus not offered the program. Secondary outcomes were CHFS scores 6 months post-randomization and functional health outcomes (Patient-Reported Outcomes Measurement Information System profile version 2.0 domain scores) 3 and 6 months post-randomization.

RESULTS

In total, 466 participants were randomized to intervention offer (N = 280) or usual care (N = 186). Of 280 participants offered the intervention, 170 (61%) consented to access the program. Of these, 117 (69%) viewed at least one hand exercise instruction video and 77 (45%) logged into the program website at least 3 times. In intent-to-treat analyses, CHFS scores were 1.2 points lower (95% CI - 2.8 to 0.3) for intervention compared to usual care 3 months post-randomization and 0.1 points lower (95% CI - 1.8 to 1.6 points) 6 months post-randomization. There were no statistically significant differences in other outcomes.

CONCLUSION

The offer to use the SPIN-HAND Program did not improve hand function. Low offer uptake, program access, and minimal usage among those who accessed the program limited our ability to determine if using the program would improve function. To improve engagement, the program could be tested in a group format or as a resource to support care provided by a physical or occupational therapist.

Sex-specific metabolic risk factors and their trajectories towards the non-alcoholic fatty liver disease incidence

PURPOSE

Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease. This study examined sex-specific associations between NAFLD and metabolic factors and investigated the trajectory of risk factors.

METHODS

We retrospectively investigated 16,140 individuals from Beijing Health Management Cohort. Univariate and multivariate time-dependent Cox regression analyses were performed to identify independent risk factors for new-onset NAFLD. The trajectory of risk factors was investigated using the latent growth curve model and growth mixture model.

RESULTS

Over a median follow-up of 3.15 years, 2,450 (15.18%) participants developed NAFLD. The risk factors for NAFLD in men were increased body mass index (BMI); waist circumference (WC); triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), haemoglobin (Hb), and serum uric acid (SUA) levels; and platelet (PLT) count and decreased serum creatinine-to-body weight (sCr/bw) and high-density lipoprotein cholesterol (HDL-C) levels. In women, the risk factors were increased BMI, WC, and fasting plasma glucose (FPG), TG, LDL-C, SUA, white blood cell (WBC), and PLT and decreased sCr/bw and HDL-C levels. In addition, BMI, LDL-C, sCr/bw and PLT changing trajectories were associated with NAFLD in men; BMI, WC, TG, LDL-C, SUA and sCr/bw trends was associated with NAFLD risk in women.

CONCLUSIONS

Development of NAFLD is associated with BMI, LDL-C, sCr/bw and PLT changing trajectories in men; BMI, WC, TG, LDL-C, SUA and sCr/bw trends are associated an increased risk of NAFLD in women. Deterioration of metabolic risk factors status can be a predictor of NAFLD many years before its occurrence.

Salmonella Infantis Meningitis in a Pediatric Patient After in-Utero Exposure to Ustekinumab

Introduction/Objective

Salmonella meningitis is associated with a significant neurological sequelae, subdural effusions, cerebral infarction, encephalitis, cerebral abscess, and high mortality. It is a rare complication of Salmonella sepsis and occurs almost exclusively during early infancy. Salmonella is identified as pathogen in less than 1% of confirmed cases of bacterial meningitis in infants. Immunocompromised individuals have higher risk of having invasive salmonellosis.

Methods/Case Report

We present a case of 4-month-old male with no significant past medical history who was presented to emergency department with five days history of fever, cough and decreased oral intake. At the time of admission, complete blood count was obtained and showed a platelet count of 702 x 10(3)/mcL, hematocrit of 25% and WBC of 17.0 x 10(3)/mcL with differential showing absolute neutrophilia and absolute monocytosis. Head ultrasound was concerning for meningoencephalitis with bilateral parenchymal echogenicity and bilateral subdural collections. Lumbar puncture showed WBC cell count of 229 (36 % PMNs, 52% lymphocytes, 12% monocytes), red blood cells of 0, glucose of 13 mg/dL, protein of 151 mg/dL. Meningitis multiplex PCR panel of the CSF was negative. MRI of the brain showed findings suggestive of meningitis with associated subdural empyema and ventriculitis without hydrocephalus. CSF culture identified Salmonella species that is susceptible to ampicillin and ceftriaxone which later identified as Salmonella infantis by the State laboratory. Immunodeficiency workup including next generation sequencing immunodeficiency panel did not reveal any known causes. Of note, mother has psoriasis and was treated with ustekinumab; an antibody against a cytokine subunit shared by IL12 and IL23, during pregnancy. The patient responded to antibiotic treatment and was discharged in a stable condition.

Results (if a Case Study enter NA)

N/A.

Conclusion

This case report highlights Salmonella infantis meningitis in a pediatric patient who was exposed to ustekinumab in utero which could cause drug induced immunodeficiency state as IL-12 is known to activate macrophages and macrophages are critical for Salmonella clearance. Although ustekinumab level was undetected in the patient right prior to discharge, the long half-life and mechanism of action of this medication could have caused an immunodeficiency state which allowed rare Salmonella infantis meningitis.

Unusual Combination of Gastrointestinal Pathogens Detected by Multiplex PCR

Introduction/Objective

Infectious gastroenteritis (IGE) is a common but complex entity which is a major cause of global morbidity and mortality. IGE is caused by a wide range of etiologic agents such as viruses, bacteria, and parasites. In the United States there are approximately 373 million of IGE cases per year. Most cases of IGE resolve without identification of a specific pathogen. Multiplex molecular assays allow identification of multiple possible pathogens with rapid turnaround time and increased sensitivity, facilitating to formulate an effective treatment plan and control measures.

Methods/Case Report

We present a case of a pediatric patient with no significant past medical history who has been having runny stools that have progressively worsened in the last 3 months and 2 days history of bloody stools with mucus before emergency room presentation. She had no fever, vomiting, joint pain, oral ulcer, and rash. Physical exam showed that the patient appeared well, nontoxic, and vital signs were within normal limit. Copious rhinorrhea was noted. She was at 50th percentile for age on the growth chart. Family denied any recent travel or sick contacts however stated that all the family members have been on well water. Complete blood count was obtained and showed a platelet count of 669 x 10(3)/mcL and WBC of 16.6 x 10(3)/mcL with differential showing absolute lymphocytosis, absolute monocytosis and absolute eosinophilia. Biofire FilmArray gastrointestinal panel performed on the stool detected Giardia lamblia, Campylobacter, Shiga-like toxin producing E. coli and Adenovirus F 40/41. Repeat of the panel per protocol detected the same four pathogens.

Results (if a Case Study enter NA)

N/A.

Conclusion

This case report highlights the significance of detecting multiple causative pathogens. While long term watery diarrhea may guide clinicians to malabsorptive process and the use of well water to Giardia, a sensitive and specific multiplex assay can detect all the pathogens involved in the disease process and greatly simplify the treatment plan for patients. This unusual combination of pathogens can explain the unique symptomology of the patient including long term watery diarrhea, recent bloody diarrhea as well as copious rhinorrhea and failure to thrive.

Effects of a support group leader education program jointly developed by health professionals and patients on peer leader self-efficacy among leaders of scleroderma support groups: a two-arm parallel partially nested randomised controlled trial

Background

More people with rare diseases likely receive disease education and emotional and practical support from peer-led support groups than any other way. Most rare-disease support groups are delivered outside of the health care system by untrained leaders. Potential benefits may not be achieved and harms, such as dissemination of inaccurate information, may occur. Our primary objective was to evaluate the effects of a rare-disease support group leader education program, which was developed collaboratively by researchers, peer support group leaders, and patient organization leaders, compared to waitlist control, on peer leader self-efficacy among scleroderma support group leaders.

Methods

The trial was a pragmatic, two-arm partially nested randomised controlled trial with 1:1 allocation into intervention or waitlist control. Eligible participants were existing or candidate peer support group leaders affiliated with a scleroderma patient organization. Leader training was delivered in groups of 5–6 participants weekly for 13 weeks in 60–90 min sessions via the GoToMeeting® videoconferencing platform. The program included 12 general leader training modules and one module specific to scleroderma. Primary outcome was leader self-efficacy, measured by the Support Group Leader Self-efficacy Scale (SGLSS) immediately post-intervention. Secondary outcomes were leader self-efficacy 3 months post-intervention; emotional distress, leader burnout, and volunteer satisfaction post-intervention and 3 months post-intervention; and program satisfaction among intervention participants post-intervention.

Results

One hundred forty-eight participants were randomised to intervention (N = 74) or waitlist (N = 74). Primary outcome data were provided by 146 (99%) participants. Mean number of sessions attended was 11.4 (standard deviation = 2.6). Mean program satisfaction score (CSQ-8) was 30.3 (standard deviation = 3.0; possible range 8–32). Compared to waitlist control, leader self-efficacy was higher post-intervention [SGLSS; 16.7 points, 95% CI 11.0–22.3; standardized mean difference (SMD) 0.84] and 3 months later (15.6 points, 95% CI 10.2–21.0; SMD 0.73); leader volunteer satisfaction was significantly higher at both assessments, emotional distress was lower post-intervention but not 3 months later, and leader burnout was not significantly different at either assessment.

Conclusions

Peer support group leader education improved leader self-efficacy substantially. The program could be easily adapted for support group leaders in other rare diseases.

Quantitative angiographic assessment of aortic regurgitation post 11 different types of TAVI devices a multicentre pooled analysis of 2665 valves

Background

Regurgitation following TAVR impacts all-cause mortality. So far, no quantitative comparison of regurgitation by the same core lab has been performed among the various commercially available transcatheter heart valves (THV) We aimed to compare quantitative angiographic aortic regurgitation (AR) of 11 different types of THVs.

Method

This is a multicentre retrospective corelab pooled analysis of aortograms from 2704 consecutive patients treated with 11 different THV devices. Analysis was done by quantitative videodensitometric aortography (LVOT-AR), which is an objective, accurate, and reproducible tool for assessment of AR following TAVR. This method relies on time density changes in contrast medium after injection in the ascending aorta and its regurgitation (and subsequent density increase) in the LVOT. The ratio between the areas under the two-time density curves of these regions quantifies the AR in absolute percentage. The valves evaluated include ACURATE neo2 (n=120), Lotus (n=546), Myval (n=108), VitaFlow (n=105), Evolut PRO (n=95), SAPIEN 3 (n=397), Evolut R (n=295), SAPIEN XT (n=239), ACURATE neo (n=120), Venus-A (n=113) and CoreValve (n=532). Stratification of continuous variable regurgitation into categorical variables was performed according to the following pre-determined threshold criteria: 1) none/trace regurgitation (LVOT-AR&lt;6%); 2) mild (6%≤ LVOT-AR ≤17%); and 3) moderate or severe (LVOT-AR &gt;17%).

Results

The addition of anti PVR sealing features to the new generations ACURATE neo2 THV proved to be effective in reduction the incidence of significant PVR In comparison with the first generation ACURATE neo.

Myval, VitaFlow and Venus-A THVs are showing promising results.

Although the incidence of moderate/severe AR has regressed over time with new generations of THVs, the incidence of mild AR is still prominent with all THVs still exhibiting mild AR with an incidence ranging between 30% and 50% with the exception of the Lotus valve that had an 19% incidence of mild AR

Conclusion

ACURATE neo2 had the lowest severe/moderate percentage of AR showing significant improvements in comparison to ACURATE neo. Myval, VitaFlow and Venus-A are promising options in the THV armamentarium. These results should be confirmed in prospective randomized, head-to-head comparisons between THVs.

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO's and Advanced Virgo's Third Observing Run

We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2  M_{⊙} and 1.0  M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14  yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200]  Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2  M_{⊙}<m_{PBH}<1.0  M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1  M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Mental Health Care Use and Associated Factors in Systemic Sclerosis: A Scleroderma Patient-Centered Intervention Network Cohort Study

Objective

Systemic sclerosis (SSc) has significant psychosocial implications. We aimed to evaluate the proportion of participants in a large international SSc cohort who used mental health services in a 3‐month period and to evaluate demographic, psychological, and disease‐specific factors associated with use.

Methods

Baseline data of participants enrolled in the Scleroderma Patient‐Centered Intervention Network Cohort were analyzed. We determined the proportion that used mental health services and the source of services in the 3 months prior to enrollment. Multivariable logistic regression was used to identify variables associated with service use.

Results

Of the 2319 participants included in the analysis, 417 (18%) used mental health services in the 3 months prior to enrollment. General practitioners were the most common mental health service providers (59%), followed by psychologists (25%) and psychiatrists (19%). In multivariable analysis, mental health service use was independently associated with higher education (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.03‐1.11), smoking (OR 1.06, 95% CI 1.02‐1.11), being retired (OR 0.60, 95% CI 0.38‐0.93), having limited SSc (OR 1.39, 95% CI 1.02‐1.89), and having higher anxiety symptom scores (OR 1.04, 95% CI 1.03‐1.06) and lower self‐efficacy scores (OR 0.90, 95% CI 0.83‐0.97). Variables not significantly associated included age, race, disease manifestations, depression symptom scores, and body image distress.

Conclusion

About 18% of participants in a large international cohort received mental health services in a 3‐month period, of whom the majority received these services from a general practitioner.

[Feasibility and perioperative safety of transoral robotic surgery with da Vinci Xi platform]

Objective: To explore the feasibility and perioperative safety of transoral robotic surgery with da Vinci Xi platform for pharyngolaryngeal tumors. Methods: A retrospective analysis was performed on 55 consecutive cases with resection of pharyngolaryngeal tumors by transoral robotic surgery with da Vinci Xi platform from July 27, 2020 to October 31, 2021 in the Department of Head and Neck Surgery, Fudan University Eye, Ear, Nose and Throat Hospital, including 44 males and 11 females, aged 25-79 years. There were 41 cases of oropharyngeal tumors, 9 cases of parapharyngeal space tumors, 2 cases of laryngeal tumors, 2 cases of hypopharyngeal tumors and 1 case of retropharyngeal space tumor. Operative time, intraoperative blood loss, postoperative hospital stay, perioperative tracheotomy, nasal feeding, hemorrhage and other complications were analyzed. Results: Of the 55 patients, 54 received resection of pharyngolaryngeal tumors by da Vinci robot through oral approach, and only 1 case of pyriform sinus carcinoma underwent a conversion to open surgery due to poor exposure of lower margin. The average surgical time for the patients with transoral robotic surgeries was 64.4 min, the average blood loss was 24.8 ml, the average postoperative hospital stay was 6.9 d, and the average oral feeding time was 11.1 d. Seventeen patients (30.9%) underwent preventive tracheotomy during surgery. Among 38 cases of laryngeal cancer, 28 underwent simultaneously neck dissection. No serious complications occurred in all patients during and after operation. The follow-up time was 1-15 months. Aside from 1 patient had a relapse 10 months after surgery, other patients had no recurrence or metastasis. Conclusion: Transoral robotic surgery with da Vinci Xi is safe, effective and minimally invasive for resection of pharyngolaryngeal tumors under reasonable indications.

A preliminary study of peripheral T-cell subsets in porokeratosis patients with MVK or MVD variants

Background

Porokeratosis (PK) is considered a skin‐specific autoinflammatory keratinization disease. Intriguingly, four causative genes of PK are in turn arranged in mevalonate pathway, with MVD variants being the commonest followed by MVK variants in a cohort of Chinese patients. Evidence indicates that mevalonate metabolites induce trained immunity in human monocytes and regulate T cells at multiple levels. Of note, γδT cells are dually regulated by intracellular and extracellular mevalonate metabolism.

Aims

To identify the possible differences in T‐cell between MVK or MVD variants from PK patients.

Materials & Methods

Targeted exome sequencing and exonic CNV screening were performed in 26 patients with PK. Sanger sequencing was used to validate all identified variants. Among them, 22 patients were identified with MVK or MVD variants. PBMCs from 22 PK patients and 27 normal controls (NCs) were analysed by flow cytometry for the frequencies of T cells subsets, including IFN‐γ‐, and TNF‐α‐producing T cells.

Results

There were 14 mutations identified in the 26 PK patients, including 6 novel mutations (MVK: c.118_226+1337dup, c.388_392delGATATinsC, c.613A>T, c.768G>C, and MVD: c.250C>T, c.988T>G). In contrast to NCs, significantly decreased frequencies of CD8⁺ and Vγ9Vδ2 T cells were observed in the PK patients with MVD variants. Moreover, it was found that dysregulated secretion of pro‐inflammatory cytokines by T cells in both PK patients with MVK and MVD variants.

Conclusions

Our findings enriched the Human Gene Mutation Databases and showed probable differences in peripheral T cells subsets between PK patients and controls.

Randomized feasibility trial of the Scleroderma Patient-centered Intervention Network Self-Management (SPIN-SELF) Program

BACKGROUND

The Scleroderma Patient-centered Intervention Network (SPIN) developed an online self-management program (SPIN-SELF) designed to improve disease-management self-efficacy in people with systemic sclerosis (SSc, or scleroderma). The aim of this study was to evaluate feasibility aspects for conducting a full-scale randomized controlled trial (RCT) of the SPIN-SELF Program.

METHODS

This feasibility trial was embedded in the SPIN Cohort and utilized the cohort multiple RCT design. In this design, at the time of cohort enrollment, cohort participants consent to be assessed for trial eligibility and randomized prior to being informed about the trial. Participants in the intervention arm are informed and provide consent, but not the control group. Forty English-speaking SPIN Cohort participants from Canada, the USA, or the UK with low disease-management self-efficacy (Self-Efficacy for Managing Chronic Disease Scale [SEMCD] score ≤ 7) who were interested in using an online self-management program were randomized (3:2 ratio) to be offered the SPIN-SELF Program or usual care for 3 months. Program usage was examined via automated usage logs. User satisfaction was assessed with semi-structured interviews. Trial personnel time requirements and implementation challenges were logged.

RESULTS

Of 40 SPIN Cohort participants randomized, 26 were allocated to SPIN-SELF and 14 to usual care. Automated eligibility and randomization procedures via the SPIN Cohort platform functioned properly, except that two participants with SEMCD scores > 7 (scores of 7.2 and 7.3, respectively) were included, which was caused by a system programming error that rounded SEMCD scores. Of 26 SPIN Cohort participants offered the SPIN-SELF Program, only 9 (35%) consented to use the program. Usage logs showed that use of the SPIN-SELF Program was low: 2 of 9 users (22%) logged into the program only once (median = 3), and 4 of 9 (44%) accessed none or only 1 of the 9 program's modules (median = 2).

CONCLUSIONS

The results of this study will lead to substantial changes for the planned full-scale RCT of the SPIN-SELF Program that we will incorporate into a planned additional feasibility trial with progression to a full-scale trial. These changes include transitioning to a conventional RCT design with pre-randomization consent and supplementing the online self-help with peer-facilitated videoconference-based groups to enhance engagement.

Exogenous melatonin prevents type 1 diabetes mellitus-induced bone loss, probably by inhibiting senescence

Exogenous melatonin inhibited the senescence of preosteoblast cells in type 1 diabetic (T1D) mice and those cultured in high glucose (HG) by multiple regulations. Exogenous melatonin had a protective effect on diabetic osteoporosis, which may depend on the inhibition of senescence.

INTRODUCTION

Senescence is thought to play an important role in the pathophysiological mechanisms underlying diabetic bone loss. Increasing evidence has shown that melatonin exerts anti-senescence effects. In this study, we investigated whether melatonin can inhibit senescence and prevent diabetic bone loss.

METHODS

C57BL/6 mice received a single intraperitoneal injection of 160 mg/kg streptozotocin, followed by the oral administration of melatonin or vehicle for 2 months. Then, tissues were harvested and subsequently examined. MC3T3-E1 cells were cultured under HG conditions for 7 days and then treated with melatonin or not for 24 h. Sirt1-specific siRNAs and MT1- or MT2-specific shRNA plasmids were transfected into MC3T3-E1 cells for mechanistic study.

RESULTS

The total protein extracted from mouse femurs revealed that melatonin prevented senescence in T1D mice. The micro-CT results indicated that melatonin prevented bone loss in T1D mice. Cellular experiments indicated that melatonin administration prevented HG-induced senescence, whereas knockdown of the melatonin receptors MT1 or MT2 abolished these effects. Sirt1 expression was upregulated by melatonin administration but significantly reduced after MT1 or MT2 was knocked down. Knockdown of Sirt1 blocked the anti-senescence effects of melatonin. Additionally, melatonin promoted the expression of CDK2, CDK4, and CyclinD1, while knockdown of MT1 or MT2 abolished these effects. Furthermore, melatonin increased the expression of the polycomb repressive complex (PRC), but knockdown of MT1 or MT2 abolished these effects. Furthermore, melatonin increased the protein levels of Sirt1, PRC1/2 complex-, and cell cycle-related proteins.

CONCLUSION

This work shows that melatonin protects against T1D-induced bone loss, probably by inhibiting senescence. Targeting senescence in the investigation of diabetic osteoporosis may lead to novel discoveries.

The Scleroderma Patient-centered Intervention Network Self-Management (SPIN-SELF) Program: protocol for a two-arm parallel partially nested randomized controlled feasibility trial with progression to full-scale trial

BACKGROUND

Systemic sclerosis (scleroderma; SSc) is a rare autoimmune connective tissue disease. We completed an initial feasibility trial of an online self-administered version of the Scleroderma Patient-centered Intervention Network Self-Management (SPIN-SELF) Program using the cohort multiple randomized controlled trial (RCT) design. Due to low intervention offer uptake, we will conduct a new feasibility trial with progression to full-scale trial, using a two-arm parallel, partially nested RCT design. The SPIN-SELF Program has also been revised to include facilitator-led videoconference group sessions in addition to online material. We will test the group-based intervention delivery format, then evaluate the effect of the SPIN-SELF Program on disease management self-efficacy (primary) and patient activation, social appearance anxiety, and functional health outcomes (secondary).

METHODS

This study is a feasibility trial with progression to full-scale RCT, pending meeting pre-defined criteria, of the SPIN-SELF Program. Participants will be recruited from the ongoing SPIN Cohort ( http://www.spinsclero.com/en/cohort ) and via social media and partner patient organizations. Eligible participants must have SSc and low to moderate disease management self-efficacy (Self-Efficacy for Managing Chronic Disease (SEMCD) Scale score ≤ 7.0). Participants will be randomized (1:1 allocation) to the group-based SPIN-SELF Program or usual care for 3 months. The primary outcome in the full-scale trial will be disease management self-efficacy based on SEMCD Scale scores at 3 months post-randomization. Secondary outcomes include SEMCD scores 6 months post-randomization plus patient activation, social appearance anxiety, and functional health outcomes at 3 and 6 months post-randomization. We will include 40 participants to assess feasibility. At the end of the feasibility portion, stoppage criteria will be used to determine if the trial procedures or SPIN-SELF Program need important modifications, thereby requiring a re-set for the full-scale trial. Otherwise, the full-scale RCT will proceed, and outcome data from the feasibility portion will be utilized in the full-scale trial. In the full-scale RCT, 524 participants will be recruited.

DISCUSSION

The SPIN-SELF Program may improve disease management self-efficacy, patient activation, social appearance anxiety, and functional health outcomes in people with SSc. SPIN works with partner patient organizations around the world to disseminate its programs free-of-charge.

An algorithmic approach to the use of rapid molecular diagnostics for SARS-CoV-2, influenza viruses, and other respiratory pathogens during an unprecedented respiratory season

Introduction/Objective

The COVID-19 pandemic exacerbated deficiencies of testing personnel, reagents, supplies and disposables, instruments, and automation in many clinical laboratories. Upon entering respiratory season, a strategy was warranted to optimize laboratory resources when supplies were already limited and expected respiratory season test volume was unknown. An algorithm was devised to prioritize test ordering and TAT based on patient clinical scenario.

Methods/Case Report

The institutional respiratory season SARS-CoV-2 algorithm was constructed by a multidisciplinary team including infectious disease, infection prevention, laboratory, and IT/LIS leadership. CDC guidance on influenza testing was incorporated. Antigen-based testing was discontinued; only molecular amplification- based platforms with FDA EUA were utilized. Platforms had a range of TAT (20 minutes to 8 hours) and included fully- automated high throughput, rapid random access, point-of-care, and CDC SARS-CoV-2 assays. Test bundles included SARS-CoV-2 (monoplex), or SARS-CoV-2 + fluA&B (triplex), or SARS-CoV-2 + respiratory pathogen panel (multiplex RPP; includes 22 targets, including flu A&B).

Results (if a Case Study enter NA)

Key factors in the algorithm included whether the patient was outpatient or inpatient, hospital employee or not, symptomatic or not, immunocompetent or immunocompromised, and whether a concurrent order for other respiratory pathogens was included or not. Clinician responses for these factors determined the type of swab collected (wet swab in VTM or dry swab) and how quickly the TAT was indicated for a given patient using a colored-dot sticker system. Priority TAT in decreasing order was symptomatic inpatients, asymptomatic pre- procedure patients, asymptomatic admissions, symptomatic employees, and symptomatic outpatients.

Conclusion

An algorithm for respiratory pathogen testing during an unprecedented respiratory season prioritizes result TAT to an individual patient’s clinical situation while maximizing laboratory stewardship by eliminating redundant influenza testing and requiring ‘all upfront’ orders to avoid add-on orders that require ‘dumpster diving’ for samples. Limitations include inherent differences in sensitivity, LOD, and specificity when multiple different platforms are utilized to detect the same analytes.

Methodological options of the nominal group technique for survey item elicitation in health research: A scoping review

OBJECTIVE

To conduct a scoping review that identifies different nominal group technique (NGT) methods used to elicit items for health surveys, and their advantages and disadvantages.

STUDY DESIGN AND SETTING

We conducted a comprehensive search process from database inception to July 22, 2019 in Medline, EMBASE, PsychInfo, CINAHL, Cochrane Central and Scopus without language restriction. We screened titles and abstracts. Data from potentially relevant articles were extracted by one reviewer and verified by a second reviewer, with disagreements resolved by consensus or a third reviewer.

RESULTS

We included 57 studies, which used between 1 and 41 nominal groups that included between 2 and 30 participants per group. We grouped the 30 identified decision points for the NGT process into two stages common to most qualitative group methods [Research objectives; Group characteristics] and three stages related to the nominal groups themselves [Eliciting survey items; Refining survey elicited items from stage 3; Evaluating and selecting final survey items]. We discuss the advantages and disadvantages of each option in relation to specific study contexts.

CONCLUSION

Investigators should carefully consider their options for each of the identified decision points and document the reasons for their choices in their protocol to maximize validity and transparency.

Genome-wide association study and inbreeding depression on body size traits in Qira black sheep (Ovis aries)

Qira black sheep is a famous indigenous sheep breed in China. The objectives of this study are to identify candidate genes related to body size, and to estimate the level of inbreeding depression on body size based on runs of homozygosity in Qira black sheep. Here, 188 adult Qira black sheep were genotyped with a high density (630 K) SNP chip and genome-wide association study for body weight and body size traits (including withers height, body slanting length, tail length, chest girth, chest width, and chest depth) were performed using an additive linear model. In consequence, 12 genome- and chromosome-wide significant SNPs and, accordingly, six candidate genes involved in muscle differentiation, metabolism and cell processes were identified. Of them, ZNF704 (zinc finger protein 704) was identified for body weight; AK2 (adenylate kinase 2) and PARK2 (parkin RBR E3 ubiquitin protein ligase) for tail length; MOCOS (molybdenum cofactor sulfurase) and ELP2 (elongator acetyltransferase complex subunit 2) for chest width; and MFAP1 (microfibril associated protein 1) for chest girth. Additionally, inbreeding depressions on body size were observed in the current herd. These results will provide insightful understandings into the genetic mechanisms of adult body size, and into the conservation and utilization of Qira black sheep.

Identification of genes associated with litter size combining genomic approaches in Luzhong mutton sheep

Litter size is one of the most important reproductive traits of sheep, which has pronounced effects on the profit of husbandry enterprises and enthusiasm of breeders. Despite the importance of litter size, the underlying genetic mechanisms have not been entirely elucidated. Therefore, based on a high-density SNP chip, genome-wide comparative analysis was performed between two groups with different fecundity to reveal candidate genes linked to litter size via detection of homozygosity and selection signatures in Luzhong mutton sheep. Consequently, nine promising genes were identified from six runs of homozygosity islands, and functionally linked to reproduction (ACTL7A, ACTL7B, and ELP1), embryonic development (KLF5 and PIBF1), and cell cycle (DACH1, BORA, DIS3, and MZT1). A total of 128 genes were observed under selection, of which HECW1 and HTR1E were related to total lambs born, GABRG3, LRP1B, and MACROD2 to teat number, and AGBL1 to reproductive seasonality. Additionally, the presence of inbreeding depression implies the urgency of reasonable mating system to increase litter size in the present herd. These findings provide a comprehensive insight to the genetic makeup of litter size, and also contribute to implementation of marker-assisted selection in sheep.

Effects of a multi-faceted education and support programme on anxiety symptoms among people with systemic sclerosis and anxiety during COVID-19 (SPIN-CHAT): a two-arm parallel, partially nested, randomised, controlled trial

Background

No trials have tested multifaceted mental health interventions recommended by public health organisations during COVID-19. The objective of this trial was to evaluate the effect of the Scleroderma Patient-centered Intervention Network COVID-19 Home-isolation Activities Together (SPIN-CHAT) Program on anxiety symptoms and other mental health outcomes among people vulnerable during COVID-19 owing to a pre-existing medical condition.

Methods

The SPIN-CHAT Trial was a pragmatic, two-arm, parallel, partially nested, randomised, controlled trial (1:1 allocation to intervention or waitlist). Eligible participants with systemic sclerosis were recruited from the international SPIN COVID-19 Cohort. SPIN COVID-19 Cohort participants were eligible for the trial if they completed baseline measures and had at least mild anxiety symptoms, had not tested positive for COVID-19, and were not currently receiving mental health counselling. SPIN-CHAT is a 4-week (3 sessions per week) videoconference-based group intervention that provided education and practice with mental health coping strategies, and provided social support to reduce isolation. Groups included 6-10 participants. The primary outcome analysed in the intention-to-treat population was anxiety symptoms (PROMIS Anxiety 4a version 1.0) immediately post-intervention. This trial is registered with ClinicalTrials.gov, NCT04335279 and is complete.

Findings

Of participants who completed baseline measures between April 9, 2020, and April 27, 2020, 560 participants were eligible and 172 participants were randomly assigned to intervention (n=86) or waitlist (n=86). Mean age was 55·0 years (SD 11·4 years), 162 (94%) were women, and 136 (79%) identified as White. In intention-to-treat analyses, the intervention did not significantly reduce anxiety symptoms post-intervention (-1·57 points, 95% CI -3·59 to 0·45; standardised mean difference [SMD] -0·22 points) but reduced symptoms 6 weeks later (-2·36 points, 95% CI -4·56 to -0·16; SMD -0·31). Depression symptoms were significantly lower 6 weeks post-intervention (-1·64 points, 95% CI -2·91 to -0·37; SMD -0·31); no other secondary outcomes were significant. No adverse events were reported.

Interpretation

The intervention did not significantly improve anxiety symptoms or other mental health outcomes post-intervention. However, anxiety and depression symptoms were significantly lower 6 weeks later, potentially capturing the time it took for new skills and social support between intervention participants to affect mental health. Multi-faceted interventions such as SPIN-CHAT have potential to address mental health needs in vulnerable groups during COVID-19, yet uncertainty remains about effectiveness.

[Evaluation of the safety and efficacy of transcatheter aortic valve replacement with domestic prostheses for patients with severely stenotic bicuspid aortic valve]

Objective: To evaluate the safety and efficacy of transcatheter aortic valve replacement (TAVR) with domestic prostheses in patients with severely stenotic bicuspid aortic valve (BAV). Methods: This study was a prospective single-center non-randomized controlled study. Patients with symptomatic severe aortic stenosis (AS), who underwent TAVR with domestic prostheses at the First Affiliated Hospital of Air Force Medical University from January 2016 to April 2020 were consecutively included in our study. Patients were divided into BAV group and tricuspid aortic valve (TAV) group according to the aortic valve morphology. Baseline characteristics, procedural outcomes were compared between the two groups, and the primary endpoint was one-month all-cause mortality. Results: A total of 100 patients aged (69.8±8.9) years were enrolled, including 71 (71%) males. There were 51 cases in BAV group and 49 cases in TAV group. Compared with TAV group, patient in the BAV group was younger ((67.1±8.6) years vs. (72.7±8.4) years, P=0.002) and had larger ascending aortic diameter at proximal part ((39.7±5.7) mm vs. (36.0±4.2) mm, P<0.001), lower Society of Thoracic Surgeons-Predicted Risk of Mortality (STS-PROM) score (3.1 (1.9, 5.4) % vs. 5.9 (2.6, 12.3) %, P=0.002). In BAV group and TAV group, the incidence of 2nd prosthesis implantation was 15.7% (8/51) and 18.4% (9/49) (P=0.721), the incidence of moderate or severe paravalvular regurgitation was 2.0% (1/51) and 0 (P=1.000), the rate of device success was 82.4% (42/51) and 81.6% (40/49) (P=0.925), respectively. One-month all-cause mortality was 2.0% (1/51) and 10.2% (5/49) (P=0.108), respectively. Echocardiography showed that postprocedural mean pressure gradient (PGmean) was higher in the BAV group (13.0 (10.0, 16.0) mmHg vs. 9.0 (7.0, 14.0) mmHg, P=0.003) (1 mmHg=0.133 kPa), but the PGmean decrease post procedure as compared with that before TAVR was similar between the two groups ((36.7±16.6) mmHg vs. (36.2±17.5) mmHg, P=0.893). Conclusion: Favorable safety and efficacy are evidenced in patients with severely stenotic BAV undergoing TAVR with domestic prostheses.

Urine-derived stem cells for the therapy of diabetic nephropathy mouse model

OBJECTIVE

Diabetic nephropathy (DN) is one of the most representative diabetic microangiopathy complications. So far, there have been no satisfactory therapeutic strategies, and the injection of stem cells provides a target for DN therapy.

PATIENTS AND METHODS

Urine-derived stem cells (USCs) were obtained from 9 healthy men. 24 mice were randomly and equally divided into control group, DN model group, DN+hUSC group (treated with USCs for 3 times). Hematoxylin-eosin (HE) and Masson staining were used to detect histological changes of kidney injury. Creatinine and blood urea nitrogen (BUN) were measured to assess renal function. Besides, myofibroblast accumulation, macrophage infiltration, cell proliferation, and oxidative stress were detected by immunohistochemical analysis.

RESULTS

Compared with DN model group, DN+hUSC group showed lower function loss, cell infiltration, and oxidative stress, as well as less renal fibrosis, histological damage, and cell proliferation.

CONCLUSIONS

USC can alleviate inflammation and oxidative stress, reduce renal interstitial fibrosis, improve renal tissue structure and protect renal function through paracrine effect.

Factors associated with fears due to COVID-19: A Scleroderma Patient-centered Intervention Network (SPIN) COVID-19 cohort study

INTRODUCTION

No studies have examined factors associated with fear in any group of people vulnerable during COVID-19 due to pre-existing medical conditions.

OBJECTIVE

To investigate factors associated with fear of consequences of COVID-19 among people living with a pre-existing medical condition, the autoimmune disease systemic sclerosis (SSc; scleroderma), including country.

METHODS

Pre-COVID-19 data from the Scleroderma Patient-centered Intervention Network (SPIN) Cohort were linked to COVID-19 data collected in April 2020. Multivariable linear regression was used to assess factors associated with continuous scores of the 10-item COVID-19 Fears Questionnaire for Chronic Medical Conditions, controlling for pre-COVID-19 anxiety symptoms.

RESULTS

Compared to France (N = 156), COVID-19 Fear scores among participants from the United Kingdom (N = 50) were 0.12 SD (95% CI 0.03 to 0.21) higher; scores for Canada (N = 97) and the United States (N = 128) were higher, but not statistically significant. Greater interference of breathing problems was associated with higher fears due to COVID-19 (Standardized regression coefficient = 0.12, 95% CI 0.01 to 0.23). Participants with higher financial resources adequacy scores had lower COVID-19 Fear scores (Standardized coefficient = -0.18, 95% CI -0.28 to -0.09).

CONCLUSIONS

Fears due to COVID-19 were associated with clinical and functional vulnerabilities in this chronically ill population. This suggests that interventions may benefit from addressing specific clinical issues that apply to specific populations. Financial resources, health policies and political influences may also be important. The needs of people living with chronic illness during a pandemic may differ depending on the social and political context in which they live.

Purification of Plasmodium and Babesia- infected erythrocytes using a non-woven fabric filter

The purification of parasite-infected erythrocytes from whole blood containing leucocytes is crucial for many downstream genetic and molecular assays in parasitology. Current methodologies to achieve this are often costly and time consuming. Here, we demonstrate the successful application of a cheap and simple Non-Woven Fabric (NWF) filter for the purification of parasitized red blood cells from whole blood. NWF filtration was applied to the malaria-parasitized blood of three strains of mice, and one strain of rat, and to Babesia gibsoni parasitized dog blood. Before and after filtration, the white blood cell (WBC) removal rates and red blood cell (RBC) recovery rates were measured. After NWF filter treatment of rodent malaria-infected blood, the WBC removal rates and RBC recovery rates were, for Kunming mice: 99.51%±0.30% and 86.12%±8.37%; for BALB/C mice: 99.61%±0.15% and 80.74%±7.11%; for C57 mice: 99.71%±0.12% and 84.87%±3.83%; for Sprague-Dawley rats: 99.93%±0.03% and 83.30%±2.96%. Microscopy showed WBCs were efficiently removed from infected dog blood samples, and there was no obvious morphological change of B. gibsoni parasites. NWF filters efficiently remove leukocytes from malaria parasite-infected mouse and rat blood, and are also suitable for filtration of B. gibsoni-infected dog blood.

Changes in mental health symptoms from pre-COVID-19 to COVID-19 among participants with systemic sclerosis from four countries: A Scleroderma Patient-centered Intervention Network (SPIN) Cohort study

INTRODUCTION

No studies have reported mental health symptom comparisons prior to and during COVID-19 in vulnerable medical populations.

OBJECTIVE

To compare anxiety and depression symptoms among people with a pre-existing medical condition and factors associated with changes.

METHODS

Pre-COVID-19 Scleroderma Patient-centered Intervention Network Cohort data were linked to COVID-19 data from April 2020. Multiple linear and logistic regression were used to assess factors associated with continuous change and ≥ 1 minimal clinically important difference (MCID) change for anxiety (PROMIS Anxiety 4a v1.0; MCID = 4.0) and depression (Patient Health Questionnaire-8; MCID = 3.0) symptoms, controlling for pre-COVID-19 levels.

RESULTS

Mean anxiety symptoms increased 4.9 points (95% confidence interval [CI] 4.0 to 5.7). Depression symptom change was negligible (0.3 points; 95% CI -0.7 to 0.2). Compared to France (N = 159), adjusted anxiety symptom change scores were significantly higher in the United Kingdom (N = 50; 3.3 points, 95% CI 0.9 to 5.6), United States (N = 128; 2.5 points, 95% CI 0.7 to 4.2), and Canada (N = 98; 1.9 points, 95% CI 0.1 to 3.8). Odds of ≥1 MCID increase were 2.6 for the United Kingdom (95% CI 1.2 to 5.7) but not significant for the United States (1.6, 95% CI 0.9 to 2.9) or Canada (1.4, 95% CI 0.7 to 2.5). Older age and adequate financial resources were associated with less continuous anxiety increase. Employment and shorter time since diagnosis were associated with lower odds of a ≥ 1 MCID increase.

CONCLUSIONS

Anxiety symptoms, but not depression symptoms, increased dramatically during COVID-19 among people with a pre-existing medical condition.

[Investigation on occupational hazards in a refrigeration equipment manufacturing enterprise]

Objective: To investigate the distribution and intensity of noise and ultraviolet radiation of welding posts in a refrigeration equipment manufacturing enterprise, in conjunction with the health status of welding workers, providing scientific evidence for the prevention and control of occupational diseases in this type of post. Methods: In May 2019, a cross-sectional survey method was used to select 576 welding workers in the pressure vessel workshop and the unit assembly workshop of a refrigeration complete equipment manufacturer from 2016 to 2018 as the research objects. The occupational hygiene survey and occupational hazard factor measurement were carried out in the workplace, and the measurement data and occupational health examination results were statistically analyzed. Results: The over standard rate of individual Lex in pressure vessel workshop was 82.2% (37/45) . Compared with the unit assembly workshop, the individual Lex of welding workers in pressure vessel workshop was higher than that in unit assembly workshop (t=13.43, P= 0.00) ; the effective irradiance exceeding rate of welding workers in pressure vessel workshop and unit assembly workshop was 33.3% (4/12) and 25.0% (3/12) , The meacurement of ovradiation in the moskment the occupational exposure limit. The deaf rate and hearing loss rate in pressure vessel workshop were 1.5% (5/336) 20.5% (69/336) , respectively, significantly higher than that in umit assembly workshop (P<0.05) . The detection rate of hearing loss of pressure vessel workshop workers increased year by year, and the difference was statistically significant (χ(2trend)=22.42, P<0.01) ; compared with the unit assembly workshop from 2016 to 2018, the detection rates of lens opacity, corneal cloudiness and hearing loss of pressure vessel workshop workers were statistically significant (χ(2)=9.45, 14.80, 55.99, P<0.01) . Conclusion: Welding workers exposed to noise and ultraviolet radiation are easy to be ignored. The enterprise management department should attach great importance to it and take comprehensive measures to protect the health of welding workers.

Combined approaches to reveal genes associated with litter size in Yunshang black goats

Intensive artificial selection has been imposed in Yunshang black goats, the first black specialist mutton goat breed in China, with a breeding object of improving reproductive performance, which has contributed to reshaping of the genome including the characterization of SNP, ROH and haplotype. However, variation in reproductive ability exists in the present population. A WGS was implemented in two subpopulations (polytocous group, PG, and monotocous group, MG) with evident differences of litter size. Following the mapping to reference genome, and SNP calling and pruning, three approaches - GWAS, ROH analysis and detection of signatures of selection - were employed to unveil candidate genes responsible for litter size. Consequently, 12 candidate genes containing OSBPL8 with the minimum P-value were uncovered by GWAS. Differences were observed in the pattern of ROH between two subpopulations that shared similar low inbreeding coefficients. Two ROH hotspots and 12 corresponding genes emerged from ROH pool association analysis. Based on the nS_L statistic, 15 and 61 promising genes were disclosed under selection for MG and PG respectively. Of them, some promising genes participate in ovarian function (PPP2R5C, CDC25A, ESR1, RPS26 and SERPINBs), seasonal reproduction (DIO3, BTG1 and CRYM) and metabolism (OSBPL8, SLC39A5 and SERPINBs). Our study pinpointed some novel promising genes influencing litter size, provided a comprehensive insight into genetic makeup of litter size and might facilitate selective breeding in goats.

Protocol for a partially nested randomised controlled trial to evaluate the effectiveness of the scleroderma patient-centered intervention network COVID-19 home-isolation activities together (SPIN-CHAT) program to reduce anxiety among at-risk scleroderma patients

OBJECTIVE

Contagious disease outbreaks and related restrictions can lead to negative psychological outcomes, particularly in vulnerable populations at risk due to pre-existing medical conditions. No randomised controlled trials (RCTs) have tested interventions to reduce mental health consequences of contagious disease outbreaks. The primary objective of the Scleroderma Patient-centered Intervention Network COVID-19 Home-isolation Activities Together (SPIN-CHAT) Trial is to evaluate the effect of a videoconference-based program on symptoms of anxiety. Secondary objectives include evaluating effects on symptoms of depression, stress, loneliness, boredom, physical activity, and social interaction.

METHODS

The SPIN-CHAT Trial is a pragmatic RCT that will be conducted using the SPIN-COVID-19 Cohort, a sub-cohort of the SPIN Cohort. Eligible participants will be SPIN-COVID-19 Cohort participants without a positive COVID-19 test, with at least mild anxiety (PROMIS Anxiety 4a v1.0 T-score ≥ 55), not working from home, and not receiving current counselling or psychotherapy. We will randomly assign 162 participants to intervention groups of 7 to 10 participants each or waitlist control. We will use a partially nested RCT design to reflect dependence between individuals in training groups but not in the waitlist control. The SPIN-CHAT Program includes activity engagement, education on strategies to support mental health, and mutual participant support. Intervention participants will receive the 4-week (3 sessions per week) SPIN-CHAT Program via videoconference. The primary outcome is PROMIS Anxiety 4a score immediately post-intervention.

ETHICS AND DISSEMINATION

The SPIN-CHAT Trial will test whether a brief videoconference-based intervention will improve mental health outcomes among at-risk individuals during contagious disease outbreak.

Reduced Siglec-7 expression on NK cells predicts NK cell dysfunction in primary hepatocellular carcinoma

Major histocompatibility complex class I (MHC-I)-dependent inhibitory receptors on natural killer (NK) cells have been found to contribute to NK cell dysfunction in hepatocellular carcinoma (HCC). However, the roles of MHC-I-independent inhibitory receptors on NK cells in HCC remain poorly defined. In this study, we analyzed the expression of the MHC-I-independent inhibitory receptors sialic acid-binding immunoglobulin-like lectin (Siglec)-7 and Siglec-9 on NK cells by analyzing the peripheral blood of 35 HCC patients and 63 healthy donors. We observed that HCC patients had lower frequencies and total numbers of NK cells in the peripheral blood. Importantly, both the expression levels of Siglec-7 on NK cells and the frequencies of Siglec-7⁺ NK cells were significantly reduced in HCC patients, which was accompanied by a decrease in activating receptor and an increase in inhibitory receptor expression on NK cells. Moreover, Siglec-7⁺ NK cells expressed higher levels of activating receptors and displayed stronger effector functions, compared with Siglec-7^- NK cells. Our findings demonstrate for the first time that reduced Siglec-7 expression predicts NK cell dysfunction in HCC patients, suggesting that Siglec-7 may be a potential marker of functional NK cell subset in HCC patients.

[Clinical outcomes of opening coronary chronic total occlusion lesions with the assistance of BridgePoint devices]

Objective: To investigate the safety, efficacy and prognosis of antegrade dissection re-entry (ADR) with the assistance of BridgePoint devices in opening coronary chronic total occlusion (CTO). Methods: A total of 87 consecutive patients, who underwent percutaneous coronary intervention using BridgePoint devices from April 2016 to December 2018 in Xijing Hospital, were included in this study. General information of the selected patients, features of CTO lesions and intraoperative parameters were recorded. Short-term outcomes including technical success rate (defined as achieving TIMI 3 blood flow with residual stenosis<30%), surgical success rate (defined as no major adverse cardiovascular events (MACE) occured while hospitalized), complications, and MACE during hospitalization were observed. MACE included death, recurrent myocardial infarction, target vascular reconstruction (TVR) and cardiac tamponade. Patients were followed up by outpatient or telephone visits at 30 days and 6, 12, 24 and 36 months after discharge. Results: Eighty-seven patients, aged (61±10) years with J-CTO scores (2.49±0.52) were included, and 75(86%) were male. Six patients underwent direct ADR with BridgePoint system, and all were successful. Eighty-one patients underwent rescue ADR using BridgePoint devices, and 62 of them were successful. The success rate of ADR with BridgePoint devices was 78.2% (68/87). Nine out of the 19 failed cases succeeded after the application of rescue antegrade/retrograde technique. The technical success rate was 88.5% (77/87). Coronary perforation occurred in 2 cases (2.3%), one case was treated with covered stent and the other case with tamponade was treated with pericardiocentesis. One patient developed periprocedural myocardial infarction, and one patient suffered from sudden death, and one patient had cardiac tamponade. In-hospital MACE occurred in 3 (3.4%) patients. The surgical success rate was 85.1% (74/87).The procedure time was (175±72)minutes and the amount of contrast used was (449±155)ml. During a follow-up of 17(11, 26) months, the incidence of MACE within 30 days was 4.7% (4/86), while 10.5% (9/86) within 6 months, 17.4% (15/86) within 17 months. Conclusion: Opening CTO with the assistance of BridgePoint devices is feasible and safe, with high success rate and satisfactory outcome.

[Changing trend in prognosis of primary hypopharyngeal carcinoma and reason analysis: date comparison of 2003-2007 and 2010-2014 in a single centre]

Objective: To explore changing trend in prognosis of primary hypopharyngeal carcinoma and to analyze the reasons at the Eye, Ear, Nose and Throat Hospital of Fudan University. Methods: We retrospectively analyzed the clinical data of 461 patients with primary hypopharyngeal carcinoma treated at the Eye, Ear, Nose and Throat Hospital of Fudan University from 2003 to 2007 (Group 1) and 2010 to 2014 (Group 2) according to the inclusion criteria. 142 from Group 1, including 133 males and 9 females, rangedfrom 38 to 82 years old and 319 from Group 2, including 313 males and 6 females, ranged from 39 to 81 years old, were included in this work. The laryngeal function preservation rate, survival outcome, application and effect of pre-and post-operative adjuvant therapy were compared. SPSS 24.0 was used for statistical analyses. Results: There were 62 patients with early disease (T1-2N0) including 18 in Group 1 and 44 in Group 2, in whom 3 (16.7%) underwent surgical procedures with laryngeal function preservation in Group 1, while, 30 (68.2%) underwent laryngeal function preservation surgery in Group 2. The laryngeal function preservation rate showed an obviously upward trend in recent years (χ(2)=13.617, P<0.001), whereas, the recurrence-free survival rate (RFS) and overall survival rate (OS) showed no significant differences between two groups (P=0.469 and 0.808, respectively). Among the 399 patients with advanced disease, 124 were in Group 1 and 275 in Group 2. After propensity score matching (PSM) was used, the OS rate was significantly higher for Group 2 than Group 1 (P=0.017), while the application of laryngeal function preservation surgery was significantly higher in Group 2 (χ(2)=4.686, P=0.030). The application rates of preoperative adjuvant therapy and postoperative adjuvant chemotherapy were significantly higher in group 2 than in group 1 (χ(2)=5.687, P=0.017; χ(2)=19.407, P<0.001). Conclusion: The application of laryngeal function preserving surgery significantly increases the retention rate of laryngeal functions in patients with early-stage hypopharyngeal carcinoma, with similar long-term survival outcomes. The application of comprehensive treatment including preoperative adjuvant therapy and postoperative adjuvant treatments, especially postoperative chemoradiotherapy, shows an obvious increase in the function preservation rate and long-term survival in patients with advanced hypopharyngeal carcinoma.
