Abstract
Background
Most microbiota studies in microscopic colitis patients are performed after diagnostic colonoscopy without considering the potential effect of colonic lavage. Patients may achieve clinical remission after colonoscopy and it is unknown whether lavage-induced changes play a role.

Aim
To assess the effect of polyethylene glycol (PEG) colonic lavage on clinical remission rate, microbial diversity, microbial dysbiosis index and specific microbial changes in patients with active microscopic colitis as compared to other diarrhoeal diseases and healthy controls.

Methods
Fifty-five consecutive patients presenting chronic watery diarrhoea and 12 healthy controls were included. Faecal samples were collected three days before and 30 days after PEG in patients and controls for microbiome analysis.

Results
Clinical remission was observed in 53% of microscopic colitis patients, and in 32% of non-microscopic colitis patients (p = 0.16). Considering patients with persisting diarrhoea after colonoscopy, 71% of non-microscopic colitis patients had bile acid diarrhoea. Baseline Shannon Index was lower in diarrhoea groups than in healthy controls (p = 0.0025); there were no differences between microscopic colitis, bile-acid diarrhoea and functional diarrhoea. The microbial dysbiosis index was significantly higher in microscopic colitis than in bile acid diarrhoea plus functional diarrhoea (p = 0.0095), but no bacterial species showed a significantly different relative abundance among the diarrheal groups.

Conclusions
Dysbiosis is a feature in active microscopic colitis, but loss of microbial diversity was similar in all diarrheal groups, suggesting that faecal microbial changes are not due to microscopic colitis itself but associated with stool form. A considerable number of microscopic colitis patients achieved clinical remission after colonoscopy, but we were unable to demonstrate related PEG-induced changes in faecal microbiome.

Abstract
Background
Perioperative chemotherapy (ChT) and preoperative chemoradiation (CRT) are both the standard treatments for locally advanced gastric cancer (LAGC). CRT can achieve a higher pathological complete regression (pCR) rate, but whether this higher pCR rate can be transformed into a long-term survival benefit remains inconclusive. Therefore, relevant studies are in progress. On the other hand, immunotherapy has been established for the first-line treatment of advanced gastric cancer (AGC) and has been widely explored in the perioperative setting. The combination of chemotherapy/radiotherapy and immunotherapy may have a synergistic effect, which will lead to a better antitumor effect. The preliminary reports of ongoing studies show promising results, including a further improved pCR rate. However, the preferred treatment combination for LAGC is still not established. To solve this problem, we are carrying out this randomized phase II trial, which aims to evaluate the efficacy and safety of perioperative chemotherapy plus the use of PD-1 antibody with or without preoperative chemoradiation for LAGC.

Methods
Eligible patients with LAGC or gastroesophageal junction (GEJ) adenocarcinoma were randomized to receive perioperative ChT, PD-1 antibody, surgery with (Arm A) or without preoperative CRT (Arm B), and PD-1 antibody maintenance until one year after surgery. The primary endpoint of this study is that the pCR rate of Arm A will be significantly higher than that of Arm B. The secondary endpoints include the pathological partial regression (pPR) rate, R0 resection rate, objective response rate (ORR), event-free survival (EFS), overall survival (OS), safety and surgical complications. Moreover, several explorative endpoints will be evaluated to find and validate the predictive biomarkers of immunotherapy.

Discussion
The results of the NeoRacing study will provide important information concerning the application of PD-1 antibody in LAGC patients during the perioperative setting. Meanwhile, the two treatment protocols will be compared in terms of efficacy and safety.

Two-year follow-up of 90 children with autism spectrum disorder receiving intensive developmental play therapy (3i method)
Authors: Brefort Eloïse , Saint-Georges-Chaumet Yann , Cohen David , Saint-Georges Catherine 
Published: June 2022

Abstract
Background
The Intensive, Interactive, and Individual (3i) intervention approach aims to decrease the severity of autism spectrum disorder (ASD) using intensive developmental play therapy (3i). We performed a retrospective study of 90 children who were enrolled for 2 years in the 3i approach to assess changes and predictors of changes in ASD severity at follow-up (FU).

Methods
The ASD severity of all patients (N = 119) who began 3i intervention between 2013 and 2018 was systematically measured using the childhood autism rating scale (CARS) and autism diagnosis interview-revised (ADI-R). Among them, 90 patients (mean age 5.6 ± 3.7 years) had a second assessment at the 2 year FU. CARS and ADI-R scores after 2 years of 3i intervention were compared to baseline scores using paired student’s t-tests. We used multiple linear regression models to assess the weight of baseline variables (e.g., age, oral language, sex, treatment intensity) on changes at the 2 year FU.

Results
Mean CARS and ADI-R subscores (interaction, communication, repetitive behaviour) decreased significantly by 20, 41, 27.5 and 25%, respectively (effect sizes: d > 0.8). Moreover, 55 and 46.7% of participants switched to a lower category of ASD severity based on the CARS scale and ADI-R interview, respectively. Multiple linear models showed that (i) a higher treatment intensity (more than 30 h per week) was significantly associated with a greater decrease (improvement) in the ADI-R interaction score; (ii) patients categorized as verbal subjects at baseline were associated with a better outcome, as ascertained by the CARS, ADI-R interaction and ADI-R communication scores; and (iii) older patients were significantly associated with a greater decrease in the ADI-R interaction score. However, we found no impact of sex, severity of ASD or comorbidities at baseline.

Conclusion
This study performed on 90 children suggests that 3i therapy may allow for a significant reduction in ASD severity with improvements in interaction, communication, and repetitive behaviours. A study using a control group is required to assess the efficacy of 3i play therapy compared to other interventions.

AbstractBackgroundWrist tuberculosis (TB) is a rare disease that may result in residual deformity, pain, or stiffness even after proper antitubercular chemotherapy (ATT) and surgical intervention. The aim of our study is to present clinical features and functional outcomes of wrist TB in a consecutive series of 84 adult patients with a minimum of 2 years of follow-up.MethodsClinical features and treatment outcomes of 84 consecutive adult patients with wrist TB from January 2003 to June 2018 including 45 men and 39 women, with a mean age of 46.8 years (18–84) were retrospectively analyzed. Data were collected on participants’ demographic details. The primary outcome measures were QuickDASH score, grip strength, Visual Analogue Scale (VAS), and PRWHE. Secondary outcomes include health-related quality of life was evaluated using the EuroQol five-dimension five-level (EQ-5D-5L), assessment and postoperative complications of patients who underwent operation were also recorded.ResultsAll 84 patients with an average follow-up of 50.8 (24–105) months. The mean duration of symptoms before treatment was 10.5 months (2–21). There were 27 patients with bony and 57 with primarily soft-tissue involvement based on preoperative evaluation of plain radiographs and MRI. There were 33 patients treated with ATT and 51 patients were treated with surgery followed by ATT. Among them, 13 patients (15.5%) underwent incision and decompression, 14 patients (16.7%) underwent wrist synovectomy, 13 patients (15.5%) underwent wrist joint fusion by plate fixation, and 11 patients (13.1%) underwent wrist joint fusion by external fixation. At the last clinical visit, the QuickDASH, and PRWHE scores of all patients decreased significantly, the VAS improved from 5.9 to 1.4, EQ-5D-5L utility index improved from 0.36 to 0.88, EQ-VAS improved from 40.2 to 89.1. All patients indicated good wrist recovery at the last follow-up, and the treatment achieved satisfactory clinical outcomes.ConclusionThe onset of wrist TB is insidious; early diagnosis, good patient compliance, and surgery combined with ATT are crucial steps for treatment of wrist TB, and also essential for the patient's postoperative recovery. Wrist arthrodesis has achieved satisfactory results in the treatment of severe wrist TB.

Abstract
Background
The establishment of symbiotic microbiota in pregnant women is important for both the mother and her offspring. Little is known about the salivary symbiotic bacteria in pregnancy, and analysis of composition of microbiome (ANCOM) is useful to detect small differences in the number of bacteria. The aim of this study was to investigate the differences in the salivary bacteria between healthy pregnant and non-pregnant women using ANCOM.

Methods
Unstimulated saliva samples were collected from 35 healthy pregnant women at 35 weeks gestation and 30 healthy non-pregnant women during menstruation. All participants underwent a periodontal examination. Estradiol and progesterone levels were examined by enzyme-linked immunosorbent assay. DNA extracted from the saliva was assessed by 16S ribosomal RNA amplicon sequencing and real-time PCR.

Results
Salivary estradiol and progesterone levels were significantly increased in pregnant women. The alpha and beta diversities were higher in pregnant women than in non-pregnant women. The largest effect size difference noted when the microbiota of the pregnant and non-pregnant women were analyzed was that for Bifidobacteriales. Levels of Bifidobacterium dentium, but not of Bifidobacterium adolescentis, were significantly increased in pregnant women, and the levels were significantly correlated with progesterone concentration.

Conclusion
The results suggest that Bifidobacterium and progesterone levels are elevated in the saliva of healthy pregnant women compared with non-pregnant women.

Abstract
Background
A brain abscess is a focal infection in which abscesses form in the brain. A brain abscess is a rare but fatal disease when rupture occurs into the ventricles. We report a case of multiple brain abscesses caused by a hematogenous infection from the apical periodontitis of deciduous teeth.

Case presentation
The patient was a 7-years and 8-months-old male with congenital heart disease. The patient sought medical attention due to fever and headache, for which he was started on three antibiotics with a diagnosis of multiple brain abscesses. Given that apical periodontitis of deciduous teeth was strongly suspected as the source of the brain abscess, the deciduous teeth were extracted. Immediately after deciduous teeth extraction, the patient’s headache and neurological symptoms disappeared.

Conclusions
After teeth extraction, a clear shrinkage of the brain abscess was observed, and the patient was discharged from the hospital.

AbstractBackgroundIndividuals with advanced Parkinson’s Disease (PD) and Parkinson-related disorders (PRD) are frequently referred for home allied therapies and nursing care, yet home healthcare professionals have limited training in PD/PRD. While recognizing the need for such care, patients and families report home healthcare professionals are unfamiliar with these conditions, which may be driven by neurophobia and may contribute to suboptimal care and early termination of services. We sought to determine the feasibility and effects of a virtual, multimodal educational intervention on PD knowledge, confidence, and empathy among home health professionals.MethodsHome health nurses, occupational therapists, physical therapists and physical therapy assistants, and speech-language pathologists participated in a daylong, virtual symposium on advanced PD/PRD, combining focused lectures, discipline-specific breakout sessions, immersive virtual reality vignettes, and interactive panels with both patients and families, and movement disorders and home healthcare experts. Participants completed online pre- and post-symposium surveys including: demographics; PD/PRD knowledge (0–10 points possible); empathy (Interpersonal Reactivity Index); and 10-point scales of confidence with and attitudes towards individuals with PD/PRD, respectively. Pre-post intervention changes and effect sizes were evaluated with paired t-tests and Cohen’s d. We performed qualitative analyses of post-symposium free-text feedback using a grounded theory approach to identify participants’ intentions to change their practice.ResultsParticipants had a mean improvement of 3.1 points on the PD/PRD knowledge test (p < 0.001, d = 1.97), and improvement in confidence managing individuals with PD/PRD (p = 0.0003, d = .36), and no change in empathy. The interactive, virtual format was rated as effective by 95%. Common themes regarding symposium-motivated practice change included: interdisciplinary collaboration; greater involvement and weighting of the patient and caregiver voice in care plans; attention to visit scheduling in relation to patient function; recognition and practical management of the causes of sudden change in PD/PRD, including infections and orthostatic hypotension.ConclusionsA virtual, multimodal, brief educational pilot intervention improved PD/PRD-specific knowledge and confidence among home healthcare nurses and allied health professionals. Future studies are necessary to test the short- and long-term effects of this intervention more broadly and to investigate the impact of this education on patient and caregiver outcomes.

Abstract
Background
A supportive clinical practicum experience may enhance the successful transition and socialization to working life of graduating nursing students. Nurse teachers have the main responsibility of supporting and guiding nursing students with their pedagogical expertise during the students’ clinical practicum. Thus, the clinical role of nurse teachers is seen as an essential part of a high-quality clinical practicum. Nursing students appreciate the nurse teacher’s cooperation with students, but it is often reported to be unattainable. The aim of this study was to explore and compare graduating nursing students’ experiences of the nurse teacher’s pedagogical cooperation with students, the clinical learning environment and supervision in their final clinical practicum, and to analyze factors associated with these experiences in six European countries.

Methods
A cross-sectional comparative international survey design was used. The modified Clinical Learning Environment, Supervision and Nurse Teacher (CLES+T) Scale, with a new subscale measuring the nurse teacher’s pedagogical cooperation with students, was used. A convenience sample of graduating nursing students in Finland, Germany, Iceland, Ireland, Lithuania and Spain completed the online survey in 2018–2019. The data were analyzed using a Chi-Square test, Pearson’s correlation coefficients, and linear models.

Results
A total of 1796 (response rate 49%) nursing students completed the survey. Overall, students had positive experiences of the nurse teacher’s pedagogical cooperation, the clinical learning environment and supervision in their final clinical practicum. Students in Spain had the most positive experiences. Educational background factors appeared to be associated with the students’ experiences of the nurse teacher’s pedagogical cooperation with students, the clinical learning environment and supervision. The relationships between the subscale Nurse teacher’s pedagogical cooperation with students and the Clinical Learning Environment and Supervision Scale were perceived as weak to strong depending on the country.

Conclusions
This study reveals that nurse teachers play an essential role in supporting and guiding nursing students’ final clinical practicum. In this light, researchers, educators, and leaders should collaborate seamlessly between educational institutions and healthcare organizations to establish the nurse teachers’ pedagogical cooperation role within the clinical learning environment.

Abstract
Background
Despite widespread efforts to create wellness programming in medical schools, there is a paucity of literature examining students’ perception of wellness and perceptions of these programs. With the inaugural class at the Arizona campus of Mayo Clinic Alix School of Medicine (MCASOM-AZ), an opportunity arose to establish an empirically evaluated wellness curriculum that most inclusively and effectively enables medical students to flourish for years to come. The initial wellness offerings included mental health, academic success, and disability services, curriculum-embedded seminars, wellness committee driven programming, and student-proposed wellness activities. We aimed to improve the relevance and impact of medical school wellness curricula by soliciting in-depth and longitudinal perspectives of medical students themselves. As MCASOM-AZ opened in 2017, the student body at the time of study consisted of first- and second-year medical students.

Methods
Employing a mixed methods analysis of qualitative and longitudinal quantitative data, first- and second-year students at a MCASOM-AZ were invited to respond to an anonymous, online year-long survey (baseline, six months and 12 months) during the 2018–2019 academic year and participate in a structured, in-depth and in-person, peer-to-peer interview about their conceptions of wellness and the MCASOM-AZ wellness curriculum and resources. Qualitative data was coded for themes using thematic analysis strategies by independent raters.

Results
Nearly half of eligible students completed the baseline survey,1/3 completed all 3 time-points, and 1/5 participated in an in-depth interview. Participant age, gender, and year of school were representative of the larger student body. Although individual conceptions varied, Wellness was consistently highly valued. Family, Academic Performance, and Friends emerged as most important to well-being across time-points. Academic work arose as the largest barrier to wellness. Analysis of qualitative data revealed five themes. Despite individual differences in approaches to wellness, wellbeing was interrelated to the learning environment; mandatory wellness efforts that didn’t address the medical culture met with skepticism.

Conclusions
Interview responses provided understanding and context by which to interpret questionnaire responses. Academics was critical to students’ identity and wellness, while also the largest barrier. Suggested curricular improvements include restructuring academic work, seamlessly integrating wellness within coursework, and offering optional individualized approaches.

Abstract
Background
The activation of the unfolded protein response (UPR) is closely linked to the pathogenesis of renal injuries. However, the role of XBP1, a crucial regulator of adaptive UPR, remains unclear during the transition from acute kidney injury (AKI) to chronic kidney disease (CKD).

Methods
We characterized XBP1 expressions in different mouse models of kidney injuries, including unilateral ischemia–reperfusion injury (UIRI), unilateral ureteral obstruction, and adenine-induced CKD, followed by generating proximal tubular XBP1 conditional knockout (XBP1cKO) mice for examining the influences of XBP1. Human proximal tubular epithelial cells (HK-2) were silenced of XBP1 to conduct proteomic analysis and investigate the underlying mechanism.

Results
We showed a tripartite activation of UPR in injured kidneys. XBP1 expressions were attenuated after AKI and inversely correlated with the severity of post-AKI renal fibrosis. XBP1cKO mice exhibited more severe renal fibrosis in the UIRI model than wide-type littermates. Silencing XBP1 induced HK-2 cell cycle arrest in G2M phase, inhibited cell proliferation, and promoted TGF-β1 secretion. Proteomic analysis identified TNF receptor associated protein 1 (Trap1) as the potential downstream target transcriptionally regulated by XBP1s. Trap1 overexpression can alleviate silencing XBP1 induced profibrotic factor expressions and cell cycle arrest.

Conclusion
The loss of XBP1 in kidney injury was profibrotic, and the process was mediated by autocrine and paracrine regulations in combination. The present study identified the XBP1-Trap1 axis as an instrumental mechanism responsible for post-AKI fibrosis, which is a novel regulatory pathway.
