Abstract
Background
Families and significant others of people with borderline personality disorder (BPD) show increased levels of psychological distress. Family Connections®, a 12-week group intervention based on the principles of Dialectical Behavior Therapy, was designed to provide families with both information about the disorder and emotion regulation skills. It has been progressively implemented in French-speaking European countries.

Methods
We conducted an observational, multicenter study in France and Switzerland. In total, 149 participants of the Family Connections program were included among five centers. Burden, depression, coping, and emotion regulation were assessed before and after the intervention.

Results
One-way repeated measures MANOVA showed that the burden, depressive symptoms, emotion regulation and coping all changed significantly after the intervention (p < 0.001, partial η2 = 0.297). T-tests showed that the burden significantly decreased after the intervention (p < 0.0001, d = -0.48), as did depressive symptoms (p < 0.0001, d = -0.36) and difficulties in emotion regulation (p < 0.0001, d =-0.32) whereas coping improved (p < 0.0001, d = 0.53). Two-way mixed ANOVA showed that burden reduction was stronger among female than male participants (p = 0.048, η2 = 0.027). Before the intervention, the burden was higher for female than male participants (p < 0.001). An initial linear regression showed the burden reduction to be associated with a decrease in the resignation of the participants (β = 0.19, p = 0.047). A second linear regression showed the burden reduction to be associated with the intensity of the relatives’ symptoms at baseline (β = 0.22, p = 0.008) and improvement of emotional clarity of the participants (β = 0.25, p = 0.006).

Conclusion
This Dialectical Behavior Therapy-Based psychoeducational intervention is an appropriate way to support French-speaking European families of people with BPD.

Published: July 2024

Abstract
Background
Orthodontic pain affects the physical and mental health of patients. The spinal trigeminal subnucleus caudalis (SPVC) contributes to the transmission of pain information and serves as a relay station for integrating orofacial damage information. Recently, glial cells have been found to be crucial for both acute and maintenance phases of pain. It has also been demonstrated that rho kinase (ROCK) inhibitors can manage different pain models by inhibiting glial cell activation. Here, we hypothesized that orthodontic pain is related to glial cells in the SPVC, and Fasudil, a representative rho/rock kinase inhibitor, can relieve orthodontic pain by regulating the function of glial cells and the related inflammatory factors. In this study, we constructed a rat model of tooth movement pain and used immunofluorescence staining to evaluate the activation of microglia and astrocytes. Quantitative real-time PCR was used to detect the release of related cytokines and the expression of pain-related genes in the SPVC. Simultaneously, we investigated the effect of Fasudil on the aforementioned indicators.

Results
In the SPVC, the expression of c-Fos peaked on day 1 along with the expression of OX42 (related to microglial activation), CD16 (a pro-inflammatory factor), and CD206 (an anti-inflammatory factor) on day 3 after tooth movement, followed by a gradual decrease. GFAP-staining showed that the number of activated astrocytes was the highest on day 5 and that cell morphology became complex. After Fasudil treatment, the expression of these proteins showed a downward trend. The mRNA levels of pro-inflammatory factors (IL-1β and TNF-α) peaked on day 3, and the mRNA expression of the anti-inflammatory factor TGF-β was the lowest 3 days after tooth movement. Fasudil inhibited the mRNA expression of pain-related genes encoding CSF-1, t-PA, CTSS, and BDNF.

Conclusion
This study shows that tooth movement can cause the activation of glial cells in SPVC, and ROCK inhibitor Fasudil can inhibit the activation of glial cells and reduce the expression of the related inflammatory factors. This study presents for the first time the potential application of Fasudil in othodontic pain.

Published: July 2024

AbstractChenopodium albumL. (CAL) has many bioactive compounds and pharmacological activities. Fermentation is the preferred modification method of releasing target bioactive. We prepared two crude polysaccharides: SLC (the polysaccharide from the unfermented stem and leaves of CAL) and FSLC (the polysaccharide from the fermented stem and leaves of CAL). In vitro antioxidant and composition of SLC and FSLC were compared, and the effects of FSLC on antioxidant activity in the IPEC-J2 cells model and development-promoting activity in the zebrafish model were evaluated. The results revealed that FSLC possesses stronger DPPH, hydroxyl radical scavenging, and reducing power than SLC. The levels of total polysaccharide, polyphenol, and flavonoid, as well as the molar ratio of glucuronic acid increased in FSLC. Compared with SLC, the relative contents of protocatechuic acid, protocatechualdehyde, gentisic acid, vanillic acid, p-coumaric acid, quercetin, ferulic acid methyl ester, hispidulin, diosmetin, cinnamic acid, isorhamnetin, syringic acid and kaempferol in FSLC increased. In IPEC-J2 cells, antioxidant enzyme activities and GSH levels were significantly increased, while the MDA level was reduced by treatment with 0.25 mg/mL FSLC. In the zebrafish model, treatment with 25 ~ 300 μg/mL of FSLC had no harmful impact on the morphology and viability of embryos at 12 ~72 hpf. At 48 and 60 hpf, treatment with 100 ~ 300 μg/mL FSLC increased the hatching rate of embryos. At 72hpf, treatment with 100 ~ 300 μg/mL FSLC could relieve morphological abnormalities caused by LPS in zebrafish and improve the hatching rate of embryos. Together, these results provide useful information on the potential for applying polysaccharides from the stems and leaves of CAL as natural feed additives to exert its antioxidant and development-promoting functions.Graphical Abstract

Abstract
Background
Striga asiatica (L.) O. Kuntze is a traditional medicinal plant rich in flavonoids, which has various pharmacological effects such as anti-hepatitis and antioxidant activities. However, there is a scarcity of resources, and artificial cultivation has not yet been achieved. This study explored the association between flavonoid metabolites and soil physicochemical properties and trace elements in different habitats, with the aim of offering theoretical guidance for the high-quality artificial cultivation of S. asiatica.

Results
The results showed that S. asiatica has low requirements for soil fertility and prefers to grow in acidic soil with high contents of potassium and available potassium, while low contents of phosphorus, nitrogen and alkali hydrolyzed nitrogen. Additionally, 1592 kinds of metabolites were identified from S. asiatica, including 78 flavonoids.

Conclusions
The flavonoid metabolites were strongly related to soil factors. Reasonable application of nitrogen and potassium fertilizers as well as controlling the contents of sodium, manganese and boron in the soil, can promote the synthesis of flavonoid metabolites in the plant. Moreover, kaempferide, glycitein, luteolin, apigenin and genistein may be the metabolic markers for identifying different regions.

F-18 FDG PET/CT scan in recurrent prosthetic valve endocarditis without detectable abnormality on echo: a case report
Authors: Denil Nurnadiah A. , Arunasalem Reana D. , Amir Hassan Siti Zarina 
Published: July 2024

Abstract
Background
Infective endocarditis poses many clinical and diagnostic challenge. The diagnosis of infective endocarditis is made by high index of clinical suspicion based on the American Heart Association modified Duke’s criteria, and the main imaging modality of choice is echocardiography.

Case presentation
Here, we reported a case of recurrent infective endocarditis revealed by FDG PET/CT study despite completion of antibiotics and negative on echocardiography. A 38-year-old female with history of double-valve replacement for aortic stenosis presented with 1-week history of chest pain, dyspnea and intermittent fever. She was treated with 5 weeks of antibiotic with IV Cephalexin for prosthetic valve endocarditis. The repeated blood culture after IV antibiotic was negative for infection. She represented again with episodes of palpitation. Post-treatment blood investigation showed normal leukocyte level with increasing CRP and Troponin T level. The repeated blood culture and transesophageal echo was negative. The F-18 FDG PET/CT showed a mild hypermetabolic focus at the inferior basal myocardial wall adjacent to the prosthetic valve, however not involving the paraaortic region which is likely secondary to ongoing inflamed myocardium. As the fear of another relapse of endocarditis, oral suppression antibiotic therapy was continued for another 6 months.

Conclusions
This case report illustrates a patient with a prosthetic valve replacement detected by F-18 FDG PET/CT, which one could have overlooked an endocarditis if one had relied on transesophageal echo (TEE) alone. F-18 FDG PET/CT is a promising adjunctive tool in the diagnostic workup of patients with suspected IE, particularly prosthetic device endocarditis where the TEE sensitivity is lower. In our patient, the positive F-18 FDG PET/CT governs the subsequent therapeutic consequences which include adjustment of antibiotic and length of treatment, and it prevents unnecessary intervention.

PURPOSE
Immunotherapy has improved survival for patients with melanoma and non–small cell lung cancer (NSCLC). Yet, as responses vary widely, immunotherapy also introduces challenges in prognostic communication. In this study, we sought to explore how patients and caregivers learned about the goal of immunotherapy and their experience of living with uncertainty.

MATERIALS AND METHODS
We conducted a qualitative study of patients with stage III or IV melanoma or stage IV NSCLC within 12 weeks of initiating or 12 months of discontinuing immunotherapy, and their caregivers. We conducted in-depth interviews with participants to explore how they learned about immunotherapy from oncology clinicians and how they experienced uncertainty. We used a framework approach to analyze interview transcripts and synthesized concepts into themes.

RESULTS
Forty-two patients and 10 caregivers participated; median age was 67 years and most were male (68%), white (95%), married (61%), and had melanoma (62%). We identified four themes: (1) the oncology team shaped participants' hopeful expectations of immunotherapy, including as a potential cure among those with melanoma; (2) distress related to prognostic uncertainty particularly affected patients who experienced toxicity or progressive disease; (3) patients who did not have long-term responses experienced overwhelming disappointment; and (4) some patients and caregivers had conflicting preferences for prognostic information. Participants provided suggestions to improve education and underscored unmet psychosocial needs.

CONCLUSION
Patients and caregivers held optimistic expectations of immunotherapy, which resulted in heightened disappointment among the subset with progression or toxicity. Clinicians should elicit information preferences of both patients and caregivers, as these may be disparate. Our results highlight the need to optimize prognostic communication and support for living with uncertainty among patients receiving immunotherapy.
Rotational Latissimus Dorsi Flap for Lateral Repair of Thoracic Cerebrospinal Fluid-Pleural Fistula: Case Report
Authors: Ambreen Yamenah , Weber Matthieu , Baum Justin , Kneuertz Peter J. , Xu David S. 
Published: July 2024

BACKGROUND AND IMPORTANCE:
Giant calcified thoracic discs are challenging surgical pathologies that tend to be more centrally located and calcified. This complicates the removal process and potentiates the formation of dural defects, resulting in persistent cerebrospinal fluid (CSF) leaks and the formation of pleural fistulas. The typical intervention for this is CSF diversion through external ventricular drain or lumbar drain placement, followed by direct repair. However, if all these measures fail, subsequent salvage techniques have not been described previously.

CLINICAL PRESENTATION:
A 45-year-old man with past medical history of obesity (body mass index: 58), hypertension, and type 2 diabetes mellitus presented to the emergency department with thoracic myelopathy symptoms. MR demonstrated a giant calcified thoracic discs at T7-T8 with severe spinal cord compression. Intraoperatively, the disc was found fused to the dura and removal caused a large ventrolateral dural dehiscence. CSF diversion and direct repair were attempted unsuccessfully, so a salvage procedure with a rotational pedicled latissimus dorsi flap was performed. The patient's latissimus dorsi was exposed and resected from attachments, maintaining thoracodorsal blood supply, while removing thoracodorsal innervation. The flap was then rotated into the previous corpectomy site. The dural defect was repaired with a sealant patch, overlayed with a parietal pleural flap and the latissimus dorsi flap. By the patient's last follow-up, he had full functional independence at home.

CONCLUSION:
We present a surgical case highlighting the challenges of managing postoperative CSF-pleural fistula occurring after giant calcified thoracic disc removal and the successful use of a novel rotational latissimus dorsi flap to definitively repair the fistula after unsuccessful primary interventions.
Thymic epithelial organoids mediate T-cell development
Authors: Hübscher Tania , Lorenzo-Martín L. Francisco , Barthlott Thomas , Tillard Lucie , Langer Jakob J. , Rouse Paul , Blackburn C. Clare , Holländer Georg , Lutolf Matthias P. 
Published: July 2024

ABSTRACT
Although the advent of organoids has opened unprecedented perspectives for basic and translational research, immune system-related organoids remain largely underdeveloped. Here, we established organoids from the thymus, the lymphoid organ responsible for T-cell development. We identified conditions enabling mouse thymic epithelial progenitor cell proliferation and development into organoids with diverse cell populations and transcriptional profiles resembling in vivo thymic epithelial cells (TECs) more closely than traditional TEC cultures. In contrast to these two-dimensional cultures, thymic epithelial organoids maintained thymus functionality in vitro and mediated physiological T-cell development upon reaggregation with T-cell progenitors. The reaggregates showed in vivo-like epithelial diversity and the ability to attract T-cell progenitors. Thymic epithelial organoids are the first organoids originating from the stromal compartment of a lymphoid organ. They provide new opportunities to study TEC biology and T-cell development in vitro, paving the way for future thymic regeneration strategies in ageing or acute injuries.

ABSTRACT
Pontocerebellar hypoplasia type 2a (PCH2a) is an ultra-rare, autosomal recessive pediatric disorder with limited treatment options. Its anatomical hallmark is hypoplasia of the cerebellum and pons accompanied by progressive microcephaly. A homozygous founder variant in TSEN54, which encodes a tRNA splicing endonuclease (TSEN) complex subunit, is causal. The pathological mechanism of PCH2a remains unknown due to the lack of a model system. Therefore, we developed human models of PCH2a using regionalized neural organoids. We generated induced pluripotent stem cell (iPSC) lines from three males with genetically confirmed PCH2a and subsequently differentiated cerebellar and neocortical organoids. Mirroring clinical neuroimaging findings, PCH2a cerebellar organoids were reduced in size compared to controls starting early in differentiation. Neocortical PCH2a organoids demonstrated milder growth deficits. Although PCH2a cerebellar organoids did not upregulate apoptosis, their stem cell zones showed altered proliferation kinetics, with increased proliferation at day 30 and reduced proliferation at day 50 compared to controls. In summary, we generated a human model of PCH2a, providing the foundation for deciphering brain region-specific disease mechanisms. Our first analyses suggest a neurodevelopmental aspect of PCH2a.
Argonaute protein CSR-1 restricts localization of holocentromere protein HCP-3, the C. elegans CENP-A homolog
Authors: Wong Charmaine Yan Yu , Tsui Hok Ning , Wang Yue , Yuen Karen Wing Yee 
Published: July 2024

ABSTRACT
Chromosome segregation errors caused by centromere malfunction can lead to chromosome instability and aneuploidy. In Caenorhabditis elegans, the Argonaute protein CSR-1 is essential for proper chromosome segregation, although the specific mechanisms are not fully understood. Here, we investigated how CSR-1 regulates centromere and kinetochore function in C. elegans embryos. We found that depletion of CSR-1 results in defects in mitotic progression and chromosome positioning relative to the spindle pole. Knockdown of CSR-1 does not affect mRNA and protein levels of the centromeric histone H3 variant and CENP-A homolog HCP-3 but does increase the localization of HCP-3 and some kinetochore proteins to the mitotic chromosomes. Such elevation of HCP-3 chromatin localization depends on EGO-1, which is an upstream factor in the CSR-1 RNA interference (RNAi) pathway, and PIWI domain activity of CSR-1. Our results suggest that CSR-1 restricts the level of HCP-3 at the holocentromeres, prevents erroneous kinetochore assembly and thereby promotes accurate chromosome segregation. Our work sheds light on the role of CSR-1 in regulating deposition of HCP-3 on chromatin and centromere function in embryos.
Joint synergy and muscle activity in the motion of the ankle–foot complex
Authors: Zhang Xinyue , Sun Ronglei 
Published: July 2024

ABSTRACT
The movement of the ankle–foot complex joints is coupled as a result of various physiological and physical constraints. This study introduces a novel approach to the analysis of joint synergies and their physiological basis by focusing on joint rotational directions and the types of muscle contractions. We developed a biomimetic model of the ankle–foot complex with seven degrees of freedom, considering the skeletal configuration and physiological axis directions. Motion capture experiments were conducted with eight participants performing dorsiflexion and plantarflexion in open-chain states, as well as various walking tasks in closed-chain states, across different ground inclinations (±10, ±5, 0 deg) and walking speeds (3 and 4 km h−1). Hierarchical cluster analysis identified joint synergy clusters and motion primitives, revealing that in open-chain movements, plantarflexion of the ankle, tarsometatarsal and metatarsophalangeal joints exhibited synergy with the inversion of the remaining joints in the complex; meanwhile, dorsiflexion was aligned with eversion. During closed-chain movements, the synergies grouping was exchanged in the subtalar, talonavicular and metatarsophalangeal joints. Further analysis showed that in open-chain movements, synergy patterns influenced by multi-joint muscles crossing oblique joint axes contribute to foot motion. In closed-chain movements, these changes in synergistic patterns enhance the propulsion of the center of mass towards the contralateral leg and improve foot arch compliance, facilitating human motion. Our work enhances the understanding of the physiological mechanisms underlying synergistic motion within the ankle–foot complex.
