Furthermore, in the rifampicin-sensitive group, the probability of recovery decreased with advancing age with a significant drop above the age of 60 years. The effect of age is negligible in the rifampicin-resistant group. We also found that type 2 diabetes mellitus has a negative effect on recovery. Coagulase-negative Staphylococci were predominant in the rifampicin-sensitive (50% of the isolates) and Gram-negative rods in the resistant group (40%).

Rifampicin resistance was associated with lower recovery rates among patients undergoing two-stage revision due to PJI. Higher age and type 2 diabetes mellitus had negative impact on clinical outcome.

Patients with inflammatory bowel disease (IBD) are susceptible to Clostridioides difficile infection (CDI), resulting in poor outcomes and recurrence; therefore, the molecular characterization of C. difficile in IBD patients in China needs further investigation.

C. difficile strains were isolated and identified from faecal samples of adult and paediatric IBD patients. Toxigenic strains were typed using multilocus sequence typing and whole genomic sequencing (WGS) to construct the phylogenetic tree. Susceptibility to 10 antimicrobials was evaluated using the Etest.

Among the 838 IBD patients, 82 toxigenic C. difficile were identified, which comprised 46 from adults and 36 children. A total of 90.2% (74/82) of the isolates were positive for both toxin A and toxin B genes (A+B+), whereas the remaining 9.8% were negative for toxin A gene but positive for toxin B gene (A-B+). These toxigenic strains were susceptible to metronidazole and vancomycin, but highly resistant to clindamycin, erythromycin, and fluorstrains. However, the molecular genetic features of the same ST type between these two groups remains highly correlated.Alterations in extracellular matrix (ECM) components that modulate inflammatory cell behavior have been shown to serve as early starters for multifactorial diseases such as fibrosis and cancer. Here, we demonstrated that loss of the ECM glycoprotein EMILIN-1 alters the inflammatory context in skin during IMQ-induced psoriasis, a disease characterized by a prominent inflammatory infiltrate and alteration of vessels that appear dilated and tortuous. Abrogation of EMILIN-1 expression or expression of the EMILIN-1 mutant E933A impairs macrophage polarization and leads to imbalanced tissue homeostasis. We found that EMILIN-1 deficiency is associated with dilated lymphatic vessels, increased macrophage recruitment and psoriasis severity. Importantly, the null or mutant EMILIN-1 background was characterized by the induction of a myofibroblast phenotype, which in turn drove macrophages towards the M1 phenotype. By using the transgenic mouse model carrying the E933A mutation in the gC1q domain of EMILIN-1, which abolishes the interaction with α4- and α9-integrins, we demonstrated that the observed changes in TGFβ signaling were due to both the EMI and gC1q domains of EMILIN-1. gC1q may exert multiple functions in psoriasis, in the context of a final, more consistent inflammatory condition by controlling skin homeostasis via interaction with both keratinocytes and fibroblasts, influencing non-canonical TGFβ signaling, and likely acting on lymphatic vessel structure and function. The analyses of human psoriatic lesions, in which lower levels of EMILIN-1 were present with a very rare association with lymphatic vessels, support the multifaceted role of this ECM component in the skin inflammatory scenario.Fibrillar proteins are principal components of extracellular matrix (ECM) that confer mechanical properties to tissues. Fibrosis can result from wound repair in nearly every tissue in adults, and it associates with increased ECM density and crosslinking as well as increased tissue stiffness. Such fibrotic tissues are a major biomedical challenge, and an emerging view posits that the altered mechanical environment supports both synthetic and contractile myofibroblasts in a state of persistent activation. Here, we review the matrisome in several fibrotic diseases, as well as normal tissues, with a focus on physicochemical properties. Stiffness generally increases with the abundance of fibrillar collagens, the major constituent of ECM, with similar mathematical trends for fibrosis as well as adult tissues from soft brain to stiff bone and heart development. Changes in expression of other core matrisome and matrisome-associated proteins or proteoglycans contribute to tissue stiffening in fibrosis by organizing collagen, crosslinking ECM, and facilitating adhesion of myofibroblasts. Understanding how ECM composition and mechanics coevolve during fibrosis can lead to better models and help with antifibrotic therapies.

We present the largest series of tubular assisted minimally invasive extraforaminal L5/S1 microdiskectomy and describe the operative nuances. An extraforaminal L5/S1 disk herniation poses a surgical challenge as a result of limited access from a high iliac crest, the sacral ala, and the large transverse process of L5 necessitating oblique working angles.

This is a case series of 28 consecutive patients who underwent tubular retractor-assisted minimally invasive extraforaminal L5/S1 microdiskectomy between 2017 and 2020 for L5 radiculopathy. Preoperative variables include demographics (age, gender); imaging characteristics (presence of spondylolisthesis, grade and presence of dynamic instability); and patient-reported measures of pain and function. Postoperatively, any complications, pain, and function were documented at 1-day, 3-month, and 12-months follow-up. Statistical analysis involved descriptive analysis of measured variables.

Patients (13 females and 15 males) had a median age of 62 years (range 32-92). One patient demonstrated grade I spondylolisthesis with no dynamic instability. Twenty-six patients (93%) achieved complete pain resolution during the follow-up period. Two patients had persistent or recurrent radicular pain, 1 of whom resolved completely with a redo tubular retractor-assisted minimally invasive microdiskectomy. No other complications were noted during the postoperative follow-up.

Tubular retractor-assisted minimally invasive extraforaminal L5/S1 microdiskectomy is an effective approach. Good surgical outcomes are achieved while avoiding the complications associated with more invasive options such as open surgery or fusion.

This study aimed to compare the educational reliability of laparoscopic hysterectomy videos on YouTube and WebSurg platforms.

We performed an online search with the keyword “laparoscopic hysterectomy” on YouTube and WebSurg. On WebSurg, the surgical interventions in gynecology section were selected. On YouTube, the most relevant surgical videos according to algorithm of YouTube were included. 22 YouTube and 22 WebSurg videos were included in the study. Technical analysis were performed via calculation of ratios such as view/day, like/view, like/subscriber, view/subscriber, and Video Power Index. The videos were evaluated with usefulness and laparoscopic surgery video educational guidelines (LAP-VEGaS) scoring systems.

View/day ratio was higher on YouTube than WebSurg [8.8 (42.1) and 2.5 (5.1), respectively; p=0.02]. Like/view ratio was lower on YouTube than WebSurg [0.006 (0.01) and 0.01 (0.02), respectively; p=0.001]. A significant difference was obtained only in the treatment section of usefulness scoring system [0 (0-2), and 0 (0-1) for YouTube and WebSurg, respectively; p=0.04]. According to LAP-VEGaS, the scores of patient positioning, step-by-step approach, demonstration of intraoperative findings and anatomy, commentary in English parameters were significantly lower on YouTube compared to WebSurg [1(0-2) and 2(2-2), p<0.001; 2 (0-2) and 2 (2-2), p=0.004; 2(0-2) and 2(2-2), p<0.001; 2(0-2) and 2(2-2), p=0.009, respectively]. The total LAP-VEGaS score of YouTube was lower than WebSurg videos [10(4-16) and 13(10-15), respectively; p=0.001).

WebSurg was found to be more reliable platform in terms of educational value and quality of laparoscopic hysterectomy videos compared to YouTube.

Illusory Contour stimuli are commonly used in conjunction with Visual Evoked Potentials (VEP) to study these filling-in processes, with characteristic modulation of the VEP in the ∼100-150 ms timeframe associated with this re-entrant processing. Substantial inter-individual variability in timing and amplitude of feedback-related VEP modulation is observed, raising the question whether this variability might underlie inter-individual differences in the ability to form strong perceptual gestalts. Backward masking paradig ms have been used to study inter-individual variance in the ability to form robust object perceptions before processing of the mask interferes with object-recognition. Some individuals recognize objects when the time between target object and mask is extremely short, whereas others struggle to do so even at longer target-to-mask intervals. We asked whether timing and amplitude of feedback-related VEP modulations were associated with individual differences in resistance to backward masking. Participants (N=40) showed substantial performance variability in detecting Illusory Contours at intermediate target-to-mask intervals (67 ms and 117 ms), allowing us to use kmeans clustering to divide the population into four performance groups (poor, low-average, high-average, superior). There was a clear relationship between the amplitude (but not the timing) of feedback-related VEP modulation and Illusory Contour detection during backward masking. We conclude that individual differences in the strength of feedback processing in neurotypical humans lead to differences in the ability to quickly establish perceptual awareness of incomplete visual objects.Human adenoviruses type 26 (HAdV26) and type 35 (HAdV35) have increasingly become the choice of adenovirus vectors for vaccine application. However, the population pre-existing immunity to these two adenoviruses in China, which may reduce vaccine efficacy, remains largely unknown. Here, we established micro-neutralizing (MN) assays to investigate the seroprevalence of neutralizing antibodies (nAbs) against HAdV26 and HAdV35 in the general population of Guangdong and Shandong provinces, China. A total of 1184 serum samples were collected, 47.0% and 15.8% of which showed HAdV26 and HAdV35 nAb activity, respectively. HAdV26-seropositive individuals tended to have more moderate nAbs titers (201-1000), while HAdV35-seropositive individuals appeared to have more low nAbs titers (72-200). The seropositive rates of HAdV26 and HAdV35 in individuals younger than 20 years old were very low. The seropositive rates of HAdV26 increased with age before 70 years old and decreased thereafter, while HAdV35 seropositive rates did not show similar characteristics.
