Cholecystectomy generally has no adverse effects on health. Studies demonstrating the association between metabolic diseases and long-term effects of cholecystectomy are increasing. preperitoneal fat thickness (PFT) is an important indicator of metabolic syndrome. Metabolic syndrome is a risk factor for sarcopenia. The aim of our study was to investigate the relationship between cholecystectomy and sarcopenia-visceral fat using the ISarcoPRM algorithm, which is an easy, reliable, and inexpensive method based on ultrasound measurement, to evaluate sarcopenia in patients with long-term previous cholecystectomy. This cross-sectional study included participants who had undergone cholecystectomy at least 5 years ago and a control group with similar characteristics. Sarcopenia was assessed using the ISarcoPRM algorithm, incorporating the sonographic thigh adjustment ratio (STAR), grip strength, and chair stand test (CST). Together with low STAR values (<1.0 for females and <1.4 for males), ow grip strength (<19 kg for females or <32 kg for males), and/or prolonged CST duration (≥12 seconds) were used to diagnose sarcopenia. Ultrasound was used to measure the visceral fat thickness. The investigation of sarcopenia and PFT values between individuals with and without cholecystectomy was planned. A total of 158 participants were included, including 89 post-cholecystectomy patients and 69 controls. Binary regression analysis revealed that cholecystectomy was positively associated with sarcopenia (OR = 2.788, 95% CI: 1.054-7.375, P = .039). However, when PFT was included, it was independently associated with sarcopenia (OR = 1.157, 95% CI: 1.067-1.254, P < .001), and the relationship with cholecystectomy disappeared (P > .05). PFT values of 10.0 mm or higher were associated with 5.875 times (95% CI: 2.035-16.961, P = .001) increased odds of sarcopenia. Sarcopenia was 2.8 times more frequent in patients who had undergone cholecystectomy than in those who had not, but this relationship was mediated by increased PFT. The risk of sarcopenia increased up to 5.875 times when the PFT exceeded 10 mm.
BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC), or more recently known as arrhythmogenic cardiomyopathy (ACM), is an heritable disorder of the myocardium characterized by progressive fibrofatty replacement the heart muscle and risk of ventricular arrhythmias and sudden cardiac death (SCD). We report a case study to demonstrate the role of gene mutation detection in risk stratification for primary prevention of SCD in a young patient diagnosed with ARVC.
CASE PRESENTATION: A 15-year-old Asian (Vietnamese) male patient with no history of documented tachyarrhythmia or syncope and a family history of potential SCD was admitted due to palpitations. Clinical findings and work-up including cardiac magnetic resonance imaging (MRI) were highly suggestive of ARVC. Gene sequencing was performed for SCD risk stratification, during which PKP2 gene mutation was found. Based on the individualized risk stratification, an ICD was implanted for primary prevention of SCD. At 6 months post ICD implantation, the device detected and successfully delivered an appropriate shock to terminate an episode of potentially fatal ventricular arrhythmia. ICD implantation was therefore proven to be appropriate in this patient.
CONCLUSIONS: While gene mutations are known to be an important factor in the diagnosis of ARVC according to the 2010 Task Force Criteria and recent clinical guidelines, their role in risk stratification of SCD remains controversial. Our case demonstrated that when used with other clinical factors and family history, this information could be helpful in identifying appropriate indication for ICD implantation.
BACKGROUND & AIMS: Natural killer (NK) cell-based anti-hepatocellular carcinoma (HCC) therapy is an increasingly attractive approach that warrants further study. Siglec-9 interacts with its ligand (Siglec-9L) and restrains NK cell functions, suggesting it is a potential therapeutic target. However, in situ Siglec-9/Siglec-9L interactions in HCC have not been reported, and a relevant interventional strategy is lacking. Herein, we aim to illustrate Siglec-9/Siglec-9L-mediated cell sociology and identify small-molecule inhibitors targeting Siglec-9 that could improve the efficacy of NK cell-based immunotherapy for HCC.
METHODS: Multiplexed immunofluorescence staining was performed to analyze the expression pattern of Siglec-7, -9 and their ligands in HCC tissues. Then we conducted docking-based virtual screening combined with bio-layer interferometry assays to identify a potent small-molecule Siglec-9 inhibitor. The therapeutic potential was further evaluated in vitro and in hepatoma-bearing NCG mice.
RESULTS: Siglec-9 expression, rather than Siglec-7, was markedly upregulated on tumor-infiltrating NK cells, which correlated significantly with reduced survival of patients with HCC. Moreover, the number of Siglec-9L+ cells neighboring Siglec-9+ NK cells was increased in HCC tissues and was also associated with tumor recurrence and reduced survival, further suggesting that Siglec-9/Siglec-9L interactions are a potential therapeutic target in HCC. In addition, we identified a small-molecule Siglec-9 inhibitor MTX-3937 which inhibited phosphorylation of Siglec-9 and downstream SHP1 and SHP2. Accordingly, MTX-3937 led to considerable improvement in NK cell function. Notably, MTX-3937 enhanced cytotoxicity of both human peripheral and tumor-infiltrating NK cells. Furthermore, transfer of MTX-3937-treated NK92 cells greatly suppressed the growth of hepatoma xenografts in NCG mice.
CONCLUSIONS: Our study provides the rationale for HCC treatment by targeting Siglec-9 on NK cells and identifies a promising small-molecule inhibitor against Siglec-9 that enhances NK cell-mediated HCC surveillance.
IMPACT AND IMPLICATIONS: Herein, we found that Siglec-9 expression is markedly upregulated on tumor-infiltrating natural killer (TINK) cells and correlates with reduced survival in patients with hepatocellular carcinoma (HCC). Moreover, the number of Siglec-9L+ cells neighboring Siglec-9+ NK cells was increased in HCC tissues and was also associated with tumor recurrence and reduced survival. More importantly, we identified a small-molecule inhibitor targeting Siglec-9 that augments NK cell functions, revealing a novel immunotherapy strategy for liver cancer that warrants further clinical investigation.
Urologic chronic pelvic pain syndrome (UCPPS) is a painful chronic condition with persistent pain originating from the pelvis that often leads to detrimental lifestyle changes in the affected patients. The syndrome develops in both sexes, with an estimated prevalence of 5.7% to 26.6% worldwide. This narrative review summarizes currently recommended therapies for UCPPS, followed by the latest animal model findings and clinical research advances in the field. The diagnosis of UCPPS by clinicians has room for improvement despite the changes in the past decade aiming to decrease the time to treatment. Therapeutic approaches targeting growth factors (i.e., nerve growth factor, vascular endothelial growth factor), amniotic bladder therapy, and stem cell treatments gain more attention as experimental treatment options for UCPPS. The development of novel diagnostic tests based on the latest advances in urinary biomarkers would be beneficial to assist with the clinical diagnosis of UCPPS. Future research directions should address the role of chronic psychologic stress and the mechanisms of pain refractory to conventional management strategies in UCPPS etiology. Testing the applicability of cognitive behavioral therapy in this cohort of UCPPS patients might be promising to increase their quality of life. The search for novel lead compounds and innovative drug delivery systems requires clinically relevant translational animal models. The role of autoimmune responses triggered by environmental factors is another promising research direction to clarify the impact of the immune system in UCPPS pathophysiology. SIGNIFICANCE STATEMENT: This minireview provides an up-to-date summary of the therapeutic approaches for UCPPS with a focus on recent advancements in the clinical diagnosis and treatments of the disease, pathophysiological mechanisms of UCPPS, signaling pathways, and molecular targets involved in pelvic nociception.

Hexabromocyclododecane (HBCD) has been detected in animals and humans blood. As an environment contamination, HBCD damages tissues and organs in animals and humans and produces cytotoxicity. In current study, we explored the effect of HBCD on premature testicular aging in vivo and in vitro. In vivo, C57 mice (8-week-old) were used as model to estimate the effect of HBCD on premature testicular aging. The results showed that testes were premature aging through measuring several aging-related markers (such as p16INK4a, hereafter p16; p21CIP, hereafter p21) in response to HBCD exposure for 20 weeks. In addition, HBCD exposure can cause oxidative stress and inflammation. Further, mouse spermatogonial cells (GC-1spg cells) were premature senescence after HBCD exposure by the evaluation of cellular senescence marker molecules. Hence, GC-1spg cell line was applied for cell model to investigate the molecule mechanism by which HBCD cause premature testicular aging., Through eliminating Fe2+ in senescent GC-1spg cells, cellular senescence was greatly alleviated. Thus, Fe2+ was identified as the key driver molecule in HBCD-induced premature cellular senescence. Next, we found that elevated iron levels in HBCD-triggered senescent GC-1spg cells were due to Nuclear receptor coactivator 4 (NCOA4)-mediated ferritinophagy. Furthermore, our results revealed that HBCD-induced senescence was caused by Fe2+ mediated oxidative stress. In summary, HBCD-induced premature testicular aging is dependent on NCOA4/Fe2+/ROS signaling molecule. The current study lays the foundation for further exploration of the effects of HBCD on reproductive toxicology.
About 10% of children may have behavioral problems during dental treatment, but the evidence for sedative protocols that benefit the care in pediatric dentistry are still weak. This randomized, masked, controlled, parallel design study aims to evaluate the efficacy, safety and cost-effectiveness of intranasal sedation with ketamine / midazolam in healthy children aged 2 to 6 years old. Children will be selected among those with dental decay that do not allow dental treatment to be performed, and need at least two restorations under local anesthesia and rubber dam isolation. It is estimated a preliminarily a sample of 84 children equally divided into three groups: A) Ketamine (4.0 mg / kg up to 100 mg) + midazolam (0.2 mg / kg, maximum 5 mg) intranasally; B) ketamine (4.0 mg / kg up to 100 mg) + midazolam (0.5 mg / kg, maximum 20 mg) orally; C) midazolam (1.0 mg / kg, maximum 20 mg) orally. The hypothesis is that ketamine / midazolam combination, administered intranasally, it constitutes an effective sedative regime, safe and cost-effective for use in pediatric dentistry in the public service. The primary endpoint is the behavior of the child. Secondary endpoints are: sedative administration acceptance, procedure memory and salivary cortisol levels within each intervention group. Additionally, we will evaluate: the occurrence of pain and associated changes in facial expressions with potentially painful stimuli in children sedated for dental care; caregivers and paediatric dentists' stress and perception about sedation; adverse events that occur during and after administration of sedatives; cost-effectiveness of the sedative protocols. The experimental design is planned to minimize systematic and random errors and to contribute to higher level of evidence in future systematic reviews. The outcomes of this study have potential impact on public and private health practice, and may support institutional guidelines dealing with this theme.
While ACL injuries are among the most common sports medicine injuries treated arthroscopically, significant debate surrounds the choice of graft used in ACLR. While graft choice has been studied extensively, allografts have been shown to have a slightly increased risk of failure than autografts. However, these differences become less pronounced with non-irradiated allografts that have not undergone chemical processing or with slower rehabilitation timelines. Allografts also show poorer graft maturation on MRI. The use of allografts may avoid the donor site morbidities associated with autograft procedures such as pain, donor site weakness, and increased surgical duration. Previous studies have documented a high prevalence of extensor and flexor weakness following autograft ACLR, with deficits in flexor strength following hamstring autograft lasting up to 12 months and extensor strength deficits at 24 months following quadriceps tendon autograft ACLR. Limiting these morbidities may allow a more predictable return to activity and improve patient satisfaction following ACLR. Despite the benefits, concern remains regarding the use of allografts in higher demand patients. However, some studies of patients undergoing ACLR show similar results between allografts and autografts.

Despite advancements in ACLR techniques, retear rates and return-to-play rates remain unsatisfactory in specific populations. Recent investigations into the persistence of anterolateral rotatory laxity in patients have led to an increased focus on the role of the anterolateral complex for knee stability. Specifically, LET has grown in popularity in the setting of ACLR. Previous studies have demonstrated that the addition of LET may improve clinical outcomes when performed in conjunction with an ACLR, possibly by decreasing post-operative pivot shift, tibial translation, and retear rates.

No study to date has compared non-irradiated allografts augmented with LET to autografts for ACLR in a randomized controlled trial fashion. This proposed study aims to understand the utility of allografts in ACLR when combined with LET.
Microdroplets of water-insoluble drugs coated with a phospholipid are prepared by sonication. As an example, microdroplets of the general anesthetic methoxyfluorane coated by a unimolecular layer of dimyRistoyl phosphatidylcholine are prepared by sonication. The microdroplets so prepared remain stable in physiologically-compatible solution, and are suitable for injection, typically intradermal or intraveneously, into a patient for inducing local anesthesia. These methoxyfluorane-containing microdroplets have been demonstrated to cause long-term local anesthesia when injected intradermally, giving duration of anesthesia 28 times longer than with other anesthetics, such as lidocaine and 11 times longer than with bupivacaine. The latter is considered longest acting conventional local anesthetic. The microdroplet is also capable of solubilizing and delivering benzocaine and other water-insoluble drugs, and thus represents a novel drug delivery system and general method for delivery of water-insoluble drugs, lowering the necessary dose and providing a more direct and timed release.
Repetitive transcranial magnetic stimulation (rTMS) is an established technology as therapy for treatment-resistant depression. The approved method for treatment is 10Hz stimulation for 40 min over the left dorsolateral prefrontal cortex (L-DLPFC). This methodology has been very successful. The limitations of this approach include the duration of the treatment (approximately 40 minutes per treatment session). Recently, researchers have aggressively pursued modifying the treatment parameters to reduce treatment times with some preliminary success. This study will investigate the efficacy of a further modified protocol, creating a more rapid form of the treatment and look at the change in neuroimaging biomarkers. In particular, this study will determine the efficacy of re-treatment in individuals who have already experienced benefit of the accelerated protocol to ensure results can be repeated.
In accordance with the present invention, there are provided rapidly crosslinkable polypeptides which are obtained upon introduction of unsaturated group(s) into the polypeptide via linkage to amino acid residues on the polypeptide directly through one of three types of linkages, namely, an amide linkage, an ester linkage, or a thioester linkage. Each of these linkages are obtainable in a single step by use of a single derivatizing agent, acrylic anhydride. Also provided are methods for preparing such modified polypeptides and various uses therefor. It has unexpectedly been found that proteins with the above-described chemical modifications have the ability to rapidly crosslink to themselves under suitable conditions. This crosslinking occurs in the absence of any external crosslinking agents (indeed, in the absence of any extraneous agents), resulting in the formation of a solid gel material. Solid crosslinked gels are formed in seconds, starting from a freely flowing solution of polypeptide. Applications of such materials are broad ranging, including the encapsulation of living cells, the encapsulation of biologically active materials, the in situ formation of degradable gels, the formation of wound dressings, the prevention of post-surgical adhesions, gene delivery, drug targetting, as a microcarrier for culture of living cells, and the like.
Climate changes leading to increasingly longer seasonal drought periods in large parts of the world increase the necessity for breeding drought-tolerant crops. Cultivated potato (Solanum tuberosum), the third most important vegetable crop worldwide, is regarded as drought-sensitive due to its shallow root architecture. Two German tetraploid potato cultivars differing in drought tolerance and their F1-progeny were evaluated under various drought scenarios. Bulked segregant analyses were combined with whole-genome sequencing (BSA-Seq) using contrasting bulks of drought-tolerant and drought-sensitive F1-clones. Applying QTLseqr, 15 QTLs comprising 588,983 single nucleotide polymorphisms (SNPs) in 2325 genes associated with drought stress tolerance were identified. SeqSNP analyses in an association panel of 34 mostly starch potato varieties using 1-8 SNPs for each of 188 selected genes narrowed the number of candidate genes down to 10. In addition, ent-kaurene synthase B was the only gene present under QTL 10. Eight of the identified genes (StABP1, StBRI1, StKS, StLEA, StPKSP1, StPKSP2, StYAB5, and StZOG1) address plant development, the other three genes (StFATA, StHGD and StSYP) contribute to plant protection under drought stress. Allelic variation in these genes might be explored in future breeding for drought-tolerant potato varieties.

Rectal implantation cysts can occur at anastomotic sites after low anterior resection (LAR) for rectal cancer. Herein, we report a case of primary adenocarcinoma arising from a rectal implantation cyst after LAR for rectal cancer. A 70-year-old woman was referred to our hospital for diagnosis and treatment of a growing cystic lesion. She had LAR performed for rectal cancer 29 years previously and had a rectal implantation cyst detected 13 years previously. On the first visit to our hospital, serum CEA and CA19-9 levels were elevated, and computed tomography (CT) scans revealed a cystic lesion near the anastomosis. CT-guided biopsy revealed no cancer tissue in the cystic lesion. After that, the cystic lesion naturally shrank, and serum CEA and CA19-9 levels became normal. Follow-up included 3 monthly serum CEA and CA19-9 testing and 6 monthly CT scans. Two years later, serum CEA and CA19-9 levels were elevated again. Colonoscopy revealed an ulcerative lesion at the anastomotic site, in which adenocarcinoma was confirmed. Abdominoperineal resection with sacral resection was performed, and postoperative histopathological examination revealed a primary adenocarcinoma with mucinous component at the implantation cyst. Since rectal implantation cysts can become malignant after extended periods, clinicians need to be aware of this disease.
Though there have been developments in clinical care and management, early and accurate diagnosis and risk stratification are still bottlenecks in septic shock patients. Since septic shock is multifactorial with patient-specific underlying co-morbid conditions, early assessment of sepsis becomes challenging due to variable symptoms and clinical manifestations. Moreover, the treatment strategies are traditionally based on their progression and corresponding clinical symptoms, not personalized. The complex pathophysiology assures that a single biomarker cannot identify, stratify, and describe patients affected by septic shock. Traditional biomarkers like CRP, PCT, and cytokines are not sensitive and specific enough to be used entirely for a patient's diagnosis and prognosis. Thus, the need of the hour is a sensitive and specific biomarker after comprehensive analysis that may facilitate an early diagnosis, prognosis, and drug development. Integration of clinical data with metabolomics would provide means to understand the patient's condition, stratify patients better, and predict the clinical outcome.
