RESUMEN

Objective: The study aimed to ascertain how Anredera cordifolia (Ten.) Steenis Gel affects the expression of protein dentin matrix protein-1 (DMP-1) in alveolar Wistar rats after tooth extraction. Materials and Methods: Rats were given A. cordifolia (Ten.) Steenis gel was in the socket after tooth extraction, and then the wound was sutured. The rats were sacrificed for 8 and 15 days following tooth extraction. The results on the 8th and 15th days demonstrate that the expression of DMP-1 in the treatment group is significantly higher than in the control group. Results: Expression of DMP-1 in the socket after tooth extraction on days 8 and 15 with a 400x magnification light microscope in both of the A. cordifolia (Ten.) Steenis gel treatment groups showed significant differences compared to the control group. Conclusion: The use of A. cordifolia (Ten.) Steenis gel can stimulate DMP-1 expression in alveolar bone after tooth extraction.

RESUMEN

Drug reactions with eosinophilia and systemic symptoms (DRESS) syndrome and Stevens-Johnson syndrome-toxic epidermal necrolysis (SJS-TEN) are reactive entities of aberrant cytotoxic immunologic reactions to exogenous medications. While they are conventionally seen as distinct, separate conditions, we present a case of a rare evolution of DRESS syndrome into SJS-TEN in the setting of simultaneous amoxicillin-clavulanate initiation and long-term sildenafil use in a 66-year-old South Asian female with a known history of prior DRESS syndrome and pulmonary arterial hypertension. We discuss the conditions leading to her unique clinical presentation and provide considerations for future clinical encounters.

RESUMEN

BACKGROUND: The modified Xiaoyao San (MXS) formula is an adjuvant drug recommended by the National Health Commission of China for the treatment of liver cancer, which has the effect of preventing postoperative recurrence and metastasis of hepatocellular carcinoma and prolonging patient survival. However, the molecular mechanisms underlying that remain unclear. AIM: To investigate the role and mechanisms of MXS in ameliorating hepatic injury, steatosis and inflammation. METHODS: A choline-deficient/high-fat diet-induced rat nonalcoholic steatohepatitis (NASH) model was used to examine the effects of MXS on lipid accumulation in primary hepatocytes. Liver tissues were collected for western blotting and immunohistochemistry (IHC) assays. Lipid accumulation and hepatic fibrosis were detected using oil red staining and Sirius red staining. The serum samples were collected for biochemical assays and NMR-based metabonomics analysis. The inflammation/lipid metabolism-related signaling and regulators in liver tissues were also detected to reveal the molecular mechanisms of MXS against NASH. RESULTS: MXS showed a significant decrease in lipid accumulation and inflammatory response in hepatocytes under metabolic stress. The western blotting and IHC results indicated that MXS activated AMPK pathway but inhibited the expression of key regulators related to lipid accumulation, inflammation and hepatic fibrosis in the pathogenesis of NASH. The metabonomics analysis systemically indicated that the arachidonic acid metabolism and steroid hormone synthesis are the two main target metabolic pathways for MXS to ameliorate liver inflammation and hepatic steatosis. Mechanistically, we found that MXS protected against NASH by attenuating the sex hormone-related metabolism, especially the metabolism of male hormones. CONCLUSION: MXS ameliorates inflammation and hepatic steatosis of NASH by inhibiting the metabolism of male hormones. Targeting male hormone related metabolic pathways may be the potential therapeutic approach for NASH.

RESUMEN

The production of transgenic animals using non-viral methods has raised questions regarding their long-term health and genomic stability. In this study, we evaluated these aspects in transgenic cattle over ten years, using transposon-mediated gene transfer. Our longitudinal analysis included a comprehensive health assessment and whole-genome DNA resequencing. We found no significant alterations in physiological parameters or health complications in transposon-mediated transgenic cattle that exceeded 10 years of age. Genomic analysis revealed that the rates of somatic mutations and copy number variations in transgenic cattle were comparable to those in non-transgenic cattle. Furthermore, structural variants were infrequent, suggesting that transposon-mediated gene insertion did not compromise genomic integrity. These findings highlight the viability of transposon systems for generating transgenic livestock, potentially expanding their applications in agriculture and biotechnology. This study contributes significantly to our understanding of the long-term implications of transgenesis in large animals and supports the safety and stability of this method.

RESUMEN

Enzymatic modification of DNA nucleobases can coordinate gene expression, nuclease protection, or mutagenesis. We recently discovered a clade of phage-specific cytosine methyltransferase (MT) and 5-methylpyrimidine dioxygenase (5mYOX) enzymes that produce 5-hydroxymethylcytosine (5hmC) as a precursor for enzymatic hypermodifications on viral genomes. Here, we identify phage MT- and 5mYOX-associated glycosyltransferases (GTs) that catalyze linkage of diverse sugars to 5hmC nucleobase substrates. Metavirome mining revealed thousands of biosynthetic gene clusters containing enzymes with predicted roles in cytosine sugar hypermodification. We developed a platform for high-throughput screening of GT-containing pathways, relying on the Escherichia coli metabolome as a substrate pool. We successfully reconstituted several pathways and isolated diverse sugar modifications appended to cytosine, including mono-, di-, or tri-saccharides comprised of hexoses, N-acetylhexosamines, or heptose. These findings expand our knowledge of hypermodifications on nucleic acids and the origins of corresponding sugar-installing enzymes.

RESUMEN

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe mucocutaneous reactions, usually to drugs, characterized by blistering and epithelial sloughing. SCORTEN is an established prognosticator index employed in SJS/TEN patients to evaluate their severity degree and mortality risk. Many studies done in the recent past have indicated that neutrophil-lymphocyte ratio (NLR) is related to disease activity in several dermatological diseases. Hence, this study has been performed to correlate the NLR of each patient with their respective SCORTEN values and assess whether NLR can be used as a prognostic marker in SJS/TEN. A single centre, retrospective, 4 year study was conducted at a tertiary care hospital. The required clinical and laboratory data were obtained from existing IP records of all cases of SJS/TEN disorders admitted in the last 4 years in our hospital between May 1st 2019 and April 30th 2023. The correlation coefficient and p value were analysed using the Spearman's rank correlation. The total sample size of the study was 22 patients. A female preponderance (59.1%) with an age range between 10 to 74 years was noted. Drugs were the main triggering factor in all the patients and antiepileptics were the most commonly implicated drug group. On statistical analysis a weak positive correlation (r = 0.182) between NLR and SCORTEN was noted, however p value was insignificant (p = 0.417). Further, mean ± SD of NLR was found to be higher in group II (patients with SCORTEN ≥ 3) as compared to group I (patients with SCORTEN < 3). On correlating NLR with each group separately, p value still remained insignificant. Elevation in NLR value reflects the systemic inflammation, but its role in predicting the severity of the disease needs further research involving larger sample size.

RESUMEN

Objective: Severe cutaneous adverse reactions (SCARs) are rare but life-threatening, with antibiotics being the main cause. This retrospective study from a single center was designed to analyze the culprit drugs, clinical features and treatment outcomes of antibiotic-induced SCARs. Methods: We analyzed cases of antibiotic-induced SCARs in a tertiary hospital in China between January 2013 and January 2024, including Steven-Johnson syndrome (SJS) or Stevens-Johnson syndrome-toxic epidermal necrolysis (SJS-TEN) overlap, toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS) and acute generalized exanthematous pustulosis (AGEP). Descriptive analysis of the demographic characteristics, clinical manifestations, treatment and prognosis were carried out. Results: Among 354 cases of SCARs, 63 validated antibiotic-related cases were included. Cephalosporins (31.7%), penicillins (25.4%), and quinolones (19.0%) were the most common triggers for SCARs. Overall, liver (50.8%), lungs (31.7%), and kidneys (23.8%) were the most frequently affected organ in SCARs cases. Eight patients (28.6%) in the SJS/SJS-TEN overlap group and 8 patients (80.0%) in the TEN group received combination therapy of corticosteroids and IVIG. Patients with SCARs caused by penicillins or cephalosporins could receive alternative treatments such as lincomamides, quinolones, and tetracyclines. The mortality rate in the TEN group was the highest at 20.0%, followed by the SJS/SJS-TEN overlap group (7.1%), and no deaths were observed in the DRESS and AGEP groups. Conclusion: The identification of the culprit antibiotics and the application of alternative antibiotic therapies are crucial for the management of antibiotic-induced SCARs. If complicated underlying conditions and complications like advanced age, cancer and pneumonia coexist with SCARs, patients might be more at risk for mortality.

RESUMEN

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) represent severe manifestations of a potentially life-threatening spectrum defined by a desquamating rash of the skin and mucous membranes. This study was prompted by the observed increase in the off-label use of lamotrigine as a causal agent in SJS/TEN in our regional burn center. METHODS: A retrospective cohort of 48 patients presenting to the Connecticut Burn Center from 2015-2022 with suspicion for SJS/TEN were reviewed for age, sex, causative drug, presenting symptoms, hospital course, biopsy confirmation, length of stay, comorbidities, and 30-day mortality. Descriptive statistical analysis was conducted to identify trends in causative agent, clinical presentation, and mortality. RESULTS: Thirty patients in our cohort received a final diagnosis of SJS/TEN. While antibiotics remain the most frequent cause of SJS/TEN across the study period (33.3 %, n = 10), the incidence of cases attributable to lamotrigine increased from 1 case between 2015 and 2018 (6.7 %) to 6 cases between 2019 and 2022 (40 %). In 2020 alone, 50 % of all cases were attributable to lamotrigine (n = 4). Of the patients where lamotrigine was implicated, 71.4 % (n = 5) were prescribed lamotrigine for off-label use in the treatment of non-bipolar mood disorders. The average lamotrigine-associated SJS/TEN patient was younger (p < 0.001), had fewer comorbidities, and was more likely to be female than the general SJS/TEN population. CONCLUSION: Off-label use of lamotrigine is emerging as a major driver of SJS/TEN with notable changes in patient demographics. Further research is necessary to understand how changing trends in the patient population will impact clinical course and optimal management.

RESUMEN

Mercury, a ubiquitous heavy metal, poses a significant threat to human health. Intravenous mercury poisoning is an uncommon but critical medical emergency. The nature and severity of its toxic effects depend on the form of mercury encountered: elemental, inorganic, or organic. It can affect almost all organ systems in the body. Chelating agents are the primary treatment for symptomatic mercury poisoning. This case report is about a 27-year-old male patient who presented to the emergency department with an alleged history of intravenous injection of mercury as an attempt at suicide, followed by breathlessness, chest pain, vomiting, and high-grade fever. He was managed with chelating therapy, non-invasive ventilation, and other supportive measures and was discharged home. After five days of discharge, he presented with fever and rashes and was diagnosed with toxic epidermal necrolysis (TEN). In spite of all aggressive management, he succumbed to death after four days of re-admission. Early intervention can significantly improve the chances of recovery. However, even with successful treatment, some individuals may experience long-term complications.

RESUMEN

Allergic diseases, characterized by a broad spectrum of clinical manifestations and symptoms, encompass a significant category of IgE-mediated atopic disorders, including asthma, allergic rhinitis, atopic dermatitis, and food allergies. These complex conditions arise from the intricate interplay between genetic and environmental factors and are known to contribute to socioeconomic burdens globally. Recent advancements in the study of allergic diseases have illuminated the crucial role of DNA methylation (DNAm) in their pathogenesis. This review explores the factors influencing DNAm in allergic diseases and delves into their mechanisms, offering valuable perspectives for clinicians. Understanding these epigenetic modifications aims to lay the groundwork for improved early prevention strategies. Moreover, our analysis of DNAm mechanisms in these conditions seeks to enhance diagnostic and therapeutic approaches, paving the way for more effective management of allergic diseases in the future.

RESUMEN

SjÓ§gren's syndrome is a systemic autoimmune disease primarily targeting the salivary and lacrimal glands. Our previous investigations have shown that administration of interleukin-22 (IL-22), an IL-10 family cytokine known for its complex and context-dependent effects on tissues, either protective- or detrimental, to salivary glands leads to hypofunction and pathological changes of salivary glands in C57BL/6 mice and in non-obese diabetic (NOD) mice, the latter being a commonly used model of SjÓ§gren's syndrome. This study aims to delineate the pathophysiological roles of endogenously produced IL-22 in the development of salivary gland pathologies and dysfunction associated with SjÓ§gren's disease in the NOD mouse model. Our results reveal that neutralizing IL-22 offered a protective effect on salivary gland function without significantly affecting the immune cell infiltration of salivary glands or the autoantibody production. Blockade of IL-22 reduced the levels of phosphorylated STAT3 in salivary gland tissues of NOD mice, while its administration to salivary glands had the opposite effect. Correspondingly, the detrimental impact of exogenously applied IL-22 on salivary glands was almost completely abrogated by a specific STAT3 inhibitor. Moreover, IL-22 blockade led to a downregulation of protein amounts of Ten-Eleven-Translocation 2, a methylcytosine dioxygenase critical for mediating interferon-induced responses, in salivary gland epithelial cells. IL-22 neutralization also exerted a protective effect on the salivary gland epithelial cells that express high levels of surface EpCAM and bear the stem cell potential, and IL-22 treatment in vitro hampered the survival/expansion of these salivary gland stem cells, indicating a direct negative impact of IL-22 on these cells. In summary, this study has uncovered a critical pathogenic role of the endogenous IL-22 in the pathogenesis of Sjögren's disease-characteristic salivary gland dysfunction and provided initial evidence that this effect is dependent on STAT3 activation and potentially achieved through fostering Tet2-mediated interferon responses in salivary gland epithelial cells and negatively affecting the EpCAMhigh salivary gland stem cells.

RESUMEN

Eribulin, a chemotherapy drug classified as a microtubule inhibitor, is known to target cell microtubule structures, impeding cancer cell growth and spread. This paper discusses a rare case of toxic epidermal necrolysis (TEN) induced by eribulin in a patient with angiosarcoma, marking it as an uncommon adverse reaction. This patient developed severe mucosal and skin lesions after the third dose of eribulin. Laboratory tests and a skin biopsy confirmed the diagnosis of TEN. The patient responded well to steroid therapy, although skin eruptions reoccurred with further eribulin treatment. This case highlights the need for further study on the immunological effects of eribulin, especially concerning severe drug eruptions potentially related to its impact on microtubule dynamics and immune cell functions.

RESUMEN

BACKGROUND: The Robson Ten Groups Classification System (RTGCS) is increasingly used to assess, monitor, and compare caesarean section (CS) rates within and between healthcare facilities. We evaluated the major contributing groups to the CS rate at Gulu Regional Referral Hospital (GRRH) in Northern Uganda using the RTGCS. METHODS: We conducted a retrospective analysis of all deliveries from June 2019 through July 2020 at GRRH, Gulu city, Uganda. We reviewed files of mothers and collected data on sociodemographic and obstetric variables. The outcome variables were Robson Ten Groups (1-10) based on parity, gestational age, foetal presentation, number of foetuses, the onset of labour, parity and lie, and history of CS. RESULTS: We reviewed medical records of 3,183 deliveries, with a mean age of 24.6 ± 5.7 years. The overall CS rate was 13.4% (n = 427). Most participants were in RTGCS groups 3 (43.3%, n = 185) and 1 (29.2%, n = 88). The most common indication for CS was prolonged labour (41.0%, n = 175), followed by foetal distress (19.9%, n = 85) and contracted pelvis (13.6%, n = 58). CONCLUSION: Our study showed that GRRH patients had a low-risk obstetric population dominated by mothers in groups 3 and 1, which could explain the low overall CS rate of 13.4%. However, the rates of CS among low-risk populations are alarmingly high, and this is likely to cause an increase in CS rates in the future. We recommend group-specific interventions through CS auditing to lower group-specific CS rates.

RESUMEN

Mesenchymal stem cells (MSCs) have promising potential for bone tissue engineering in bone healing and regeneration. They are regarded as such due to their capacity for self-renewal, multiple differentiation, and their ability to modulate the immune response. However, changes in the molecular pathways and transcription factors of MSCs in osteogenesis can lead to bone defects and metabolic bone diseases. DNA methylation is an epigenetic process that plays an important role in the osteogenic differentiation of MSCs by regulating gene expression. An increasing number of studies have demonstrated the significance of DNA methyltransferases (DNMTs), Ten-eleven translocation family proteins (TETs), and MSCs signaling pathways about osteogenic differentiation in MSCs. This review focuses on the progress of research in these areas.

RESUMEN

This data article introduces a comprehensive dataset of real-world truck parking locations across Europe. The dataset comprises N = 19,713 designated parking sites classified according to public accessibility and suitability for heavy-duty trucks (HDTs). More specifically, core information comprises the truck stop category, latitude and longitude information, area size, and country assignment. Furthermore, additional information such as truck traffic flow volumes, proximity to the highway network, and land use information provide supplemental data on ambient conditions and thus enhance the contextual relevance of those locations. The dataset was systematically generated using OpenStreetMap (OSM) data, focusing on parking areas, rest areas, and fueling stations as predominant public truck parking sites. These locations were evaluated and filtered for truck accessibility and suitability and then complemented and validated using commercial truck routing / geocoding software. Further refinement was achieved by Mean-Shift clustering. The further integration of supplementary datasets increased the information level, and all clustered locations were labeled into four archetypal categories. Finally, filtering retained only confidently classified publicly accessible and truck-certified parking and service facilities. This dataset assists in finding real-world stop options for HDTs during national or international operations and identifying suitable and most attractive sites for deploying alternative charging or refueling infrastructures along the European transport network. Accordingly, it can serve as a valuable resource for research in traffic science, future energy systems, and alternative truck powertrains. Its added value extends to diverse stakeholders like Charge Point Operators (CPOs), truck manufacturers, logistics companies, and public authorities.

RESUMEN

Early trophoblast differentiation is crucial for embryo implantation, placentation and fetal development. Dynamic changes in DNA methylation occur during preimplantation development and are critical for cell fate determination. However, the underlying regulatory mechanism remains unclear. Recently, we derived morula-like expanded potential stem cells from human preimplantation embryos (hEPSC-em), providing a valuable tool for studying early trophoblast differentiation. Data analysis on published datasets showed differential expressions of DNA methylation enzymes during early trophoblast differentiation in human embryos and hEPSC-em derived trophoblastic spheroids. We demonstrated downregulation of DNA methyltransferase 3 members (DNMT3s) and upregulation of ten-eleven translocation methylcytosine dioxygenases (TETs) during trophoblast differentiation. While DNMT inhibitor promoted trophoblast differentiation, TET inhibitor hindered the process and reduced implantation potential of trophoblastic spheroids. Further integrative analysis identified that glutamyl aminopeptidase (ENPEP), a trophectoderm progenitor marker, was hypomethylated and highly expressed in trophoblast lineages. Concordantly, progressive loss of DNA methylation in ENPEP promoter and increased ENPEP expression were detected in trophoblast differentiation. Knockout of ENPEP in hEPSC-em compromised trophoblast differentiation potency, reduced adhesion and invasion of trophoblastic spheroids, and impeded trophoblastic stem cell (TSC) derivation. Importantly, TET2 was involved in the loss of DNA methylation and activation of ENPEP expression during trophoblast differentiation. TET2-null hEPSC-em failed to produce TSC properly. Collectively, our results illustrated the crucial roles of ENPEP and TET2 in trophoblast fate commitments and the unprecedented TET2-mediated loss of DNA methylation in ENPEP promoter.

RESUMEN

BACKGROUND: Integrating behavioral health services into pediatric primary care can improve access to care, especially for children marginalized by poverty and racial/ethnic minority status. In primary care, a common presenting concern is attention-deficit/hyperactivity disorder (ADHD). Services in primary care for marginalized children with ADHD typically include medication alone; therapy to improve skills and build relationships is less available. This study evaluates the effectiveness of a behavioral intervention offered through primary care for marginalized families coping with ADHD (Partnering to Achieve School Success, PASS) compared to treatment as usual (TAU). METHOD: Three hundred participants will be randomly assigned to PASS or TAU. Participants include children ages 5 to 11 who have ADHD and are from economically marginalized families. PASS is a personalized, enhanced behavioral intervention that includes evidence-based behavior therapy strategies and enhancements to promote family engagement, increase caregiver distress tolerance, and provide team-based care to improve academic and behavioral functioning. TAU includes services offered by primary care providers and referral for integrated behavioral health or community mental health services. Outcomes will be assessed at mid-treatment (8 weeks after baseline), post-treatment (16 weeks), and follow-up (32 weeks) using parent- and teacher-report measures of service use, child academic, behavioral, and social functioning, parenting practices, family empowerment, and team-based care. Mixed effects models will examine between-group differences at post-treatment and follow-up. Analyses will examine the mediating role of parenting practices, family empowerment, and team-based care. Subgroup analyses will examine differential effects of intervention by child clinical characteristics and socioeconomic factors. DISCUSSION: This study is unique in targeting a population of children with ADHD marginalized by low socioeconomic resources and examining an intervention designed to address the challenges of families coping with chronic stress related to poverty. TRIAL REGISTRATION: This study was registered on clinicaltrials.gov (NCT04082234) on September 5, 2019, prior to enrollment of the first participant. The current version of the protocol and IRB approval date is October 4, 2023. Results will be submitted to ClinicalTrials.gov no later than 30 days prior to the due date for the submission of the draft of the final research report to the Patient-Centered Outcomes Research Institute.

RESUMEN

PURPOSE: In medication management, the ten right principles framework is an accepted global nursing standard and an important component of medication safety. Especially pediatric patients have a higher risk of harm in medication administration compared to adults. This study aimed to examine the experiences of pediatric nurses in implementing the ten right principles in safe medication management. DESIGN AND METHODS: A descriptive phenomenological approach was used in this study. The study was conducted with 16 pediatric nurses in a public hospital's Pediatric Service and Neonatal Intensive Care Unit. Pediatric nurses' medication practices were observed, and semi-structured interviews were conducted with the nurses after the observation. Observations were conducted using an observation tool, and interviews were conducted using a semi-structured interview form. Qualitative data were analyzed using thematic analysis. RESULTS: In this study, it was observed that although pediatric nurses generally adhered to the ten right principles, they had the most difficulties with the right dose and time principles. As a result of the interviews conducted after the observation, two themes (factors facilitating the implementation of the ten right principles and difficulties in implementing the ten right principles) were formed. CONCLUSIONS: The findings revealed that pediatric nurses achieved safe and effective medication administration and generally adhered to the ten right principles. PRACTICE IMPLICATIONS: This study highlights the positive contribution of pediatric nurses to patient safety by using multiple sources of information and clinical reasoning strategies despite the difficulties they experience in drug administration.
