Published: April 2023

Background: The advantages of remnant tissue preservation in anterior cruciate ligament (ACL) reconstruction (ACLR) remain controversial. Hypothesis: It was hypothesized that a large amount of remnant tissue, especially if anatomically positioned, would improve patient-reported outcomes and second-look graft appearance after preserved double-bundle ACLR (DB-ACLR). Study Design: Cohort study; Level of evidence, 3. Methods: This retrospective study included 89 consecutive patients who underwent unilateral remnant-preserving DB-ACLR using 2 hamstring tendon autografts. The authors categorized the arthroscopic findings into 3 groups according to the location and volume of the ACL remnant tissue in the femoral notch: (1) anatomical attachment (group AA; n = 34); (2) nonanatomical attachment (group NA; n = 33); and (3) no remnant (group NR; n = 22). Based on second-look arthroscopy, the reconstructed graft was graded as excellent, fair, or poor. Patient-reported outcomes were evaluated at 2 years after surgery using the Knee injury and Osteoarthritis Outcome Score (KOOS) and the Japanese Anterior Cruciate Ligament Questionnaire–25 (JACL-25). Results: The AA and NA groups had a significantly shorter time from injury to surgery compared with the NR group ( P = .0165). Considering the second-look arthroscopic findings, the authors found a significant difference in synovial coverage of the grafts between the 3 groups ( P = .0018). There were no significant differences in the overall KOOS and JACL-25 score among the 3 groups; however, the KOOS–Sport and Recreation and KOOS–Quality of Life subscale scores were significantly higher in the AA group compared with the NA and NR groups ( P = .0014 and .0039, respectively). The JACL-25 score for middle- to high-speed flexion and extension was significantly better in the AA group versus the NR group ( P = .0261). Conclusion: This study showed that preserving anatomically positioned and adequate remnant tissue during DB-ACLR improved second-look graft appearance and KOOS–Sport and Recreation and KOOS–Quality of Life scores.

Authors: Battin Alexander O. , Hobeika Natalie , Zdilla Matthew J. 
Published: April 2023

Abstract
Background
Medicinal leech therapy, otherwise known as hirudotherapy or leeching, has been utilized for numerous pathologies over centuries. The technique resurfaced in modern medicine for its beneficial effects in microsurgical complications, particularly venous congestion. Recently, several cases have documented the utilization of medicinal leech therapy for the management of urologic disease states and surgical complications. It is important to understand the past, present, and future possibilities for hirudotherapy in urology. However, a systematic review of medical leech therapy in this context has yet to be conducted. Accordingly, and with an emphasis on salient clinical details, this study aims to systematically review the cases of hirudotherapy applied to urological conditions.

Main body of the abstract
A systematic review of cases in MEDLINE/PubMed was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Of 49 search results, 11 articles detailing 13 unique cases of medicinal leech therapy used in the urological context were included. Hirudotherapy was conducted in 10 of 13 cases (76.9%) for the management of congested blood occurring in five cases post-penile replantation, two cases of postoperative scrotal hematoma, two cases of venous congestion of the glans post-neonatal bladder exstrophy repair, and one case of refractory priapism. Leeching in the remaining three cases was for the management of penoscrotal edema in patients with hormone refractory prostate carcinoma treated with radical radiation therapy. All 13 cases (100%) reported clinical improvement from hirudotherapy. Venous congestion/hematoma cases noted decreased displaced blood volume. The patient experiencing priapism reported decreased pain despite the persistence of cavernosal swelling. The three cases of penoscrotal edema reported significant decreases in swelling due to serous fluid drainage from leech puncture sites. No complications or side effects were reported in the nine adult patients. The four postoperative neonatal patients all required blood product throughout treatment.

Short conclusion
The systematic review of the cases demonstrates that medicinal leech therapy is a favorable treatment option for individuals with varied urological pathologies and that hirudotherapy may improve post-surgical outcomes in the urological setting. Hirudotherapy should be considered as a viable treatment modality in specific venostatic urological conditions.

Published: April 2023

Abstract
Background
Increasing evidence indicates that radiotherapy (RT) has synergistic inhibitory efficiency with immunotherapy agents in multiple cancers and enhances abscopal effects by regulating the innate immune response, which was further investigated in this study. Neutrophils are recruited in radiated tumors. Therefore, neutrophil membrane-coated nanoparticles potentially deliver R837 (Toll-like receptor 7 agonist) to radiated tumors.

Methods
A novel nanoparticle R837@PLGA@Neu was prepared by initially assembling PLGA (poly (lactic-co-glycolic acid)) with R837 (TLR7 agonist) into R837@PLGA followed by coating with neutrophil membrane. Characterizations of R837@PLGA@Neu were performed. Tumor targeting efficiency was evaluated by in vivo fluorescent imaging of CT26-bearing mice. Treatments of R837@PLGA@Neu combined with RT were carried out in unilateral and bilateral CRC tumor-bearing mice, followed by validations of immune cells in tumors by flow cytometry.

Results
The characteristics of R837@PLGA@Neu were well identified, and it was confirmed to have high uptake ability and low cytotoxicity in colorectal cancer (CRC) cells in vitro, as well as its strong tumor-targeting efficiency in vivo in CRC tumor-bearing mice. The exciting findings were that R837@PLGA@Neu combined with RT exerted prominent tumor inhibition not only in radiated tumors, but also in distant tumors without RT, suggesting its enhancement of the efficacy and abscopal effect of RT. The possible underlying mechanisms were remodeling of the tumor microenvironment by triggering mature dendritic cells and CD8+ T cells.

Conclusion
In summary, our findings suggested that neutrophil membrane-derived nanoparticle R837@PLGA@Neu with high uptake ability and low cytotoxicity showed strong tumor-targeting efficiency, and combination with RT had a promising effect in CT26-bearing mice via immune cell regulation. Our results provide a probable combination strategy for CRC treatment.

Abstract
Background
Diarrhea is one of the most common diseases in pig industry, which seriously threatens the health of piglets and causes huge economic losses. Enterotoxigenic Escherichia coli (ETEC) F4 is regarded as the most important cause of diarrhea in piglets. Some pigs are naturally resistant to those diarrheas caused by ETEC-F4, because they have no F4 receptors (F4R) on their small intestine epithelial cells that allow F4 fimbriae adhesion. Circular RNA (circRNA) has been shown to play an important regulatory role in the pathogenesis of disease. We hypothesized that circRNAs may also regulate the adhesion of piglet small intestinal epithelial cells to ETEC F4 fimbriae. However, the circRNA expression profiles of piglets with different Enterotoxigenic Escherichia coli F4 fimbriae (ETEC-F4ac) adhesion phenotypes are still unclear, and the intermediate regulatory mechanisms need to be explored. Hence, the present study assessed the circRNA expression profiling in small intestine epithelial cells of eight male piglets with different ETEC-F4 adhesion phenotypes and ITGB5 genotypes to unravel their regulatory function in susceptibility to ETEC-F4ac diarrhea. Piglets were divided into two groups: non-adhesive group (n = 4) with CC genotype and adhesive group (n = 4) with TT genotype.

Results
The RNA-seq data analysis identified 13,199 circRNAs from eight samples, most of which were exon-derived. In the small intestine epithelial cells, 305 were differentially expressed (DE) circRNAs between the adhesive and non-adhesive groups; of which 46 circRNAs were upregulated, and 259 were downregulated. Gene ontology and KEGG enrichment analysis revealed that most significantly enriched DE circRNAs’ host genes were linked to cytoskeletal components, protein phosphorylation, cell adhesion, ion transport and pathways (such as adherens junction, gap junction) associated with ETEC diarrhea. The circRNA-miRNA-mRNA interaction network was also constructed to elucidate their underlying regulatory relationships. Our results identified several candidate circRNAs that affects susceptibility to ETEC diarrhea. Among them, circ-SORBS1 can adsorb ssc-miR-345-3p to regulate the expression of its host gene SORBS1, thus improving cell adhesion.

Conclusion
Our results provided insights into the regulation function of circRNAs in susceptibility to ETEC diarrhea of piglets, and enhanced our understanding of the role of circRNAs in regulating ETEC diarrhea, and reveal the great potential of circRNA as a diagnostic marker for susceptibility of ETEC diarrhea in piglets.

Abstract
Background
Coevolution between pathogens and their hosts decreases host morbidity and mortality. Bats host and can tolerate viruses which can be lethal to other vertebrate orders, including humans. Bat adaptations to infection include localized immune response, early pathogen sensing, high interferon expression without pathogen stimulation, and regulated inflammatory response. The immune reaction is costly, and bats suppress high-cost metabolism during torpor. In the temperate zone, bats hibernate in winter, utilizing a specific behavioural adaptation to survive detrimental environmental conditions and lack of energy resources. Hibernation torpor involves major physiological changes that pose an additional challenge to bat-pathogen coexistence. Here, we compared bat cellular reaction to viral challenge under conditions simulating hibernation, evaluating the changes between torpor and euthermia.

Results
We infected the olfactory nerve-derived cell culture of Myotis myotis with an endemic bat pathogen, European bat lyssavirus 1 (EBLV-1). After infection, the bat cells were cultivated at two different temperatures, 37 °C and 5 °C, to examine the cell response during conditions simulating euthermia and torpor, respectively. The mRNA isolated from the cells was sequenced and analysed for differential gene expression attributable to the temperature and/or infection treatment. In conditions simulating euthermia, infected bat cells produce an excess signalling by multitude of pathways involved in apoptosis and immune regulation influencing proliferation of regulatory cell types which can, in synergy with other produced cytokines, contribute to viral tolerance. We found no up- or down-regulated genes expressed in infected cells cultivated at conditions simulating torpor compared to non-infected cells cultivated under the same conditions. When studying the reaction of uninfected cells to the temperature treatment, bat cells show an increased production of heat shock proteins (HSPs) with chaperone activity, improving the bat’s ability to repair molecular structures damaged due to the stress related to the temperature change.

Conclusions
The lack of bat cell reaction to infection in conditions simulating hibernation may contribute to the virus tolerance or persistence in bats. Together with the cell damage repair mechanisms induced in response to hibernation, the immune regulation may promote bats’ ability to act as reservoirs of zoonotic viruses such as lyssaviruses.

Published: April 2023

Abstract
Background
Artemisia is important medicinal plants in China and are widely used in medicine, agriculture, and food. Pharmacologically active components of the plants remain to be investigated.

Methods
This study sought to identify and compare the chemical constituents of three species of Artemisia in Tibet using a widely-targeted metabolomics approach and their antibacterial and antioxidant capacities were determined.

Result
A total of 1109 metabolites within 10 categories were detected from the three species of Artemisia, including lipids, amino acids, nucleotides, flavonoids, terpenes, coumarins, organic acids, and phenolic acids. 732 different metabolites have been identified between Artemisia sieversiana and Artemisia annua, 751 different metabolites were identified between Artemisia wellbyi and A. sieversiana, and 768 differential metabolites were differentially detected from A. wellbyi and A. annua. Differentially identified compounds included flavonoids, phenolic acids, artemisinins and coumarin. A. annua contained the highest relative content of artemisinin among three Artemisia. The antimicrobial experiments showed that the three Artemisia species had strong antibiotic activities against Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Proteus mirabilis and Pseudomonas aeruginosa. The biochemical analysis showed that the three species of Artemisia have strong antioxidant capacity.

Conclusions
This is the first reported attempt to comparatively determine the types of the metabolites of the three widely distributed Artemisia species in Tibet. The information should help medicinal research and facilitate comprehensive development and utilization of Artemisia species in Tibet.
Rheumatism as a cause of cardiac hemangioma: a rare case report and review of literature with special focus on etiology
Authors: Xie Ting , Masroor Matiullah , Chen Xuan , Liu Fujin , Zhang Jie , Yang Dayan , Liu Cong , Xiang Mei 
Published: April 2023

Abstract
Background
Cardiac hemangioma is a very rare benign tumor of the heart which accounts for 1–2% of all primary cardiac tumors. Multiple cardiac hemangiomas are even rarer with only three cases published in the literature. Pathologically it can be divided into cavernous hemangioma, capillary hemangioma, arteriovenous hemangioma, mixed-type hemangioma, and so on. At present, the etiology of cardiac hemangioma is not completely clear. In this study, we present multiple cardiac hemangiomas located in the right atrium and discuss the new unreported possible cause (rheumatism) of cardiac hemangioma. This is the fourth case of multiple cardiac hemangiomas in the medical literature and the first time to present rheumatism as the cause of cardiac hemangioma.

Case presentation
A 53-year-old man presented to the clinic with intermittent chest tightness and shortness of breath for 2 years. On echocardiography, multiple soft tissue masses in the right atrium were found. The patient had rheumatic heart disease with severe mitral stenosis and moderate tricuspid regurgitation. Two masses with a diameter of about 20 mm and 15 mm were seen in the right atrium. One mass was located on the inferior margin of the fossa ovalis and the other was adjacent to the inferior vena cava. Both masses were successfully removed surgically. The mitral valve replacement and tricuspid valve plasty were performed at the same time. The postoperative histopathology results confirmed the diagnosis of cavernous hemangioma.

Conclusion
The occurrence of multiple hemangiomas in the heart is possible, especially in the presence of rheumatism. Rheumatism is one of the possible etiologies of cardiac hemangioma. Cardiologists and cardiac surgeons should be aware of its occurrence and should consider cardiac hemangioma as a differential diagnosis especially in rheumatic heart disease patients when they present with soft tissue cardiac masses for accurate management.

Published: April 2023

Abstract
Background
Integrating evidence-based interventions for people with alcohol use disorder (AUD) into primary healthcare (PHC) can increase access to care and reduce morbidity, mortality, and population burden. However, for the integration to be feasible, acceptable, and sustainable, there is a need to contextualize the approach and involve stakeholders. Therefore, this study aimed to use participatory methods to adapt a model for integrating AUD interventions in Tanzania’s PHC system at the community, facility, and organizational levels.

Methods
A mixed-methods study was used. Participants include key mental health stakeholders, experts, and PHC providers. We conducted a situational analysis to investigate opportunities and constraints in the existing systems of care, utilizing data available from the routine collection and/or in the public domain, individual semi-structured interviews (n = 11), and focus group discussions (3 groups; total n = 26 participants) and a series of theory of change (ToC) workshops (n = 32). Data from the three methods were triangulated to develop the adapted model for integrating interventions for AUD in PHC.

Results
A situational appraisal revealed limited community, facility, and organizational resources and infrastructures for supporting services delivery of integrated AUD interventions. Also, shortage of health workforce, inadequate health management information systems, and limited medical supply and financing. Nevertheless, the theory of change proposed integrated AUD intervention packages and strategies to facilitate integrated care for people with AUD. Additionally, the barriers and facilitators for implementing these integrated AUD interventions and how to overcome them were explored.

Conclusions
The adapted model for the integrated AUD intervention in Tanzanian PHC revealed limited resources and system functioning for facilitating integrated AUD services. Nevertheless, it proposes the needed integrated AUD interventions and its barriers, facilitators, and strategies for overcoming them. There is a need to pilot the adapted model to inform plans for more comprehensive implementation or scaling up.
TalkingMats as a decision aid to promote involvement in choice and decision-making around home care services for older people with mild to moderate dementia – study protocol for a randomized controlled trial
Authors: Dunér Anna , Bångsbo Angela , Olsson Tina M. 
Published: April 2023

AbstractBackgroundIn Sweden, 72% of people with dementia live in ordinary housing. Of these, 50% receive home care services. Older people with dementia may benefit from developments in decision-making support which aim to facilitate their ability to communicate their personal needs and preferences with care managers and staff in home care services. In this study, we will test and evaluate the use of TalkingMats in Swedish municipal home care services for older people with mild to moderate dementia. TalkingMats is a low-technology communication tool, to help people with communication difficulties express their views. It uses a simple system of picture symbols which are placed on a textured mat. This study will provide insight into the extent to which TalkingMats benefits older people with dementia to feel more involved in decisions related to home care services. In addition, this study will assess the extent to which the use of TalkingMats promotes service providers’ efforts to involve service recipients in decision making. The implementation of TalkingMats in home care services will also be studied.MethodsA parallel group, two-armed randomized controlled trial design in which TalkingMats and Usual Conversation Method will be compared. Two specific situations where older people with dementia must make decisions about home care services will be studied. First, a follow-up needs-assessment conversation between study participants and care managers will be studied. Second, a conversation between participants and home care staff regarding the delivery of the decided home care services will be studied. In addition, a qualitative approach will be used to gain an understanding of study participant and service provider experiences of the impact and implementation of TalkingMats.DiscussionThe combined exploratory, descriptive, and experimental study design is considered an important strength which will facilitate multi-facetted knowledge production concerning the involvement and communication needs of older people with dementia generally and within the context of home care services specifically. Combining qualitative and quantitative methods will maximize our ability to assess the effects of TalkingMats.Trial registrationClinicalTrials.gov ID:NCT05561998. Registered in September 28, 2022.
