Oligometastatic Breast Cancer: Seeking the Cure by Redefining Stage IV Disease?

Breast cancer represents one of the most common malignancies worldwide. In early stages a combination of treatment strategies are offered with curative intent, whereas the therapeutic aim in metastatic disease is to provide the longest possible survival with an acceptable quality of life. The term "oligometastasis", first described by Hellmann and Weichselbaum in 1995, represents an intermediate state between local and systemic disease, where radical focal treatments to all metastatic lesions might have a curative potential. Due to sufficient lack of data, the proper management of oligometastatic disease remains even until today a highly unmet need. Surgery, radiotherapy or ablation (radiofrequency or cryotherapy) are among the local eradication therapies that could offer long-term outcomes in patients with oligometastatic breast cancer (OMBC). The present review aims to bring the readers up to the latest data regarding the management of OMBC according to the different organs involved by setting a framework of current treatment paradigms. It also brings to the forefront debatable questions requiring multidisciplinary approach and highlights the concerns arising from dealing with this clinically and biologically unique entity in everyday clinical practice.

Neoplasias mamária e esplênica em cadela

Regarding mammary and splenic neoplasms in dogs, the surgical therapeutic approach is often the method of choice, given its curative potential and the possibility of subsequent histopathological analysis. In veterinary medicine, the incidence of mammary neoplasms is high, especially in unneutered female dogs. Breast carcinoma in situ, with its histological particularities and clinical behavior, requires a careful diagnosis and a precise therapeutic approach, carrying out additional tests such as cytopathology and ultrasound to adequately define the treatment. Surgical excision, associated with the evaluation of adjacent healthy breast tissue, is essential to ensure complete removal of neoplastic tissue, plus it is also indicated to perform ovariohysterectomy (OVH) together with mastectomy. Spleen tumors are similarly common in dogs, especially hemangiosarcoma, which is notable for its aggressiveness and high metastatic rate. Therefore, early diagnosis and precise interventions are essential for a good prognosis, with the affected organ being often removed in its entirety. Therefore, we report the case of a female Shih-Tzu dog, 7 years old and weighing 4kg, who presented, upon palpation, a nodule in the left M3 measuring <1cm with absence of nodular secretion, change in color, itching local or galactorrhea. The patient was referred for regional mastectomy and OVH after cytological examination compatible with carcinoma and, in a pre-operative ultrasound examination, a singular hypoechoic nodular formation, discretely heterogeneous, vascularized on Doppler and in close contact with the splenic capsule was noted in the spleen in its medial parietal portion, measuring 0.96 cm in its longest axis. Thus, during intraoperative visual inspection after OVH and upon approval from the owner, it was decided to perform total splenectomy and, after histopathological examination, it was known that the organ was affected by hemangiosarcoma. The canine was discharged from the hospital a few hours after the end of the surgery, without the subsequent use of adjuvant therapies.

Controlled release of hydrogel-encapsulated mesenchymal stem cells-conditioned medium promotes functional liver regeneration after hepatectomy in metabolic dysfunction-associated steatotic liver disease

BackgroundGlobally, prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing, and there is an urgent need to develop innovative therapies that promote liver regeneration following hepatectomy for this disease. Surgical excision is a key therapeutic approach with curative potential for liver tumors. However, hepatic steatosis can lead to delayed liver regeneration and higher post-operative complication risk. Mesenchymal stem cells-conditioned medium (MSC-CM) is considered a rich source of paracrine factors that can repair tissues and restore function of damaged organs. Meanwhile, hydrogels have been widely recognized to load MSC secretome and achieve sustained release. This study aimed to evaluate the therapeutic effect of hydrogel-encapsulated MSC-CM on liver regeneration following partial hepatectomy (PHx) in a rodent model of diet-induced hepatic steatosis.MethodsMale Lewis rats were fed with a methionine and choline–deficient diet. After 3 weeks of feeding, PHx was performed and rats were randomly allocated into two groups that received hydrogel-encapsulated MSC-CM or vehicle via the intra-mesenteric space of the superior mesenteric vein (SMV).ResultsThe regeneration of the remnant liver at 30 and 168 h after PHx was significantly accelerated, and the expressions of proliferating cell nuclear antigen were significantly enhanced in the MSC-CM group. MSC-CM treatment significantly increased hepatic ATP and β-hydroxybutyrate content at 168 h after PHx, indicating that MSC-CM fosters regeneration not only in volume but also in functionality. The number of each TUNEL- and cleaved caspase-3 positive nuclei in hepatocytes at 9 h after PHx were significantly decreased in the MSC-CM group, suggesting that MSC-CM suppressed apoptosis. MSC-CM increased serum immunoregulatory cytokine interleukin-10 and interleukin-13 at 30 h after PHx. Additionally, mitotic figures and cyclin D1 expression decreased and hepatocyte size increased in the MSC-CM group, implying that this mode of regeneration was mainly through cell hypertrophy rather than cell division.ConclusionsMSC-CM represents a novel therapeutic approach for patients with MASLD requiring PHx.

Cell Therapy and the Skin: Great Potential but in Need of Optimization.

Cell therapy is rapidly growing owing to its therapeutic potential for diseases with currently poor outcomes. Cell therapy encompasses both nonengineered and engineered cells and possesses unique abilities such as sense-and-respond functions and long-term engraftment for persistent curative potential. Cell therapy capabilities have expanded to address a wide spectrum of diseases, and our review is focused on dermatological applications. The use of fibroblasts and keratinocytes as cell therapy has shown promise in skin disorders such as epidermolysis bullosa. Future efforts include testing the ability of fibroblasts to reprogram nonvolar to volar skin to reduce stump dermatoses in patients with limb loss using prosthetics.

Insight to Biofabrication of Liver Microtissues for Disease Modeling: Challenges and Opportunities.

In the last decade, liver diseases with high mortality rates have become one of the most important health problems in the world. Organ transplantation is currently considered the most effective treatment for compensatory liver failure. An increasing number of patients and shortage of donors has led to the attention of reconstructive medicine methods researchers. The biggest challenge in the development of drugs effective in chronic liver disease is the lack of a suitable preclinical model that can mimic the microenvironment of liver problems. Organoid technology is a rapidly evolving field that enables researchers to reconstruct, evaluate, and manipulate intricate biological processes in vitro. These systems provide a biomimetic model for studying the intercellular interactions necessary for proper organ function and architecture in vivo. Liver organoids, formed by the self-assembly of hepatocytes, are microtissues and can exhibit specific liver characteristics for a long time in vitro. Hepatic organoids are identified as an impressive tool for evaluating potential cures and modeling liver diseases. Modeling various liver diseases, including tumors, fibrosis, non-alcoholic fatty liver, etc., allows the study of the effects of various drugs on these diseases in personalized medicine. Here, we summarize the literature relating to the hepatic stem cell microenvironment and the formation of liver Organoids.

Hematopoietic Cell Transplant compared with Standard Care in Adolescents and Young Adults with Sickle Cell Disease

Disease-modifying therapies are standard of care (SOC) for sickle cell disease (SCD), but hematopoietic cell transplantation (HCT) has curative potential. We compared outcomes prospectively through 2-years after biologic assignment to a Donor or No Donor (SOC) Arm based on the availability of an HLA-matched sibling or unrelated donor (BMTCTN 1503; NCT02766465). A donor search was commenced after eligibility confirmation. The primary endpoint was the comparison of survival 2 years after biologic assignment between treatment arms. Power calculations required 60 participants on the Donor Arm and 140 on the No Donor Arm to determine if early transplant-related mortality might be balanced by disease-related mortality over a longer period of follow-up. Secondary objectives compared changes in SCD-related events, functional outcomes, and organ function. Data were analyzed by the intent-to-treat principle. A total of 113 participants were enrolled, 28 on the Donor and 85 on the No Donor Arm The 2-year probabilities of survival were 89% and 93%, on the Donor and No Donor Arms, respectively. Vaso-occlusive pain (VOC) was less frequent on the Donor Arm in the second year after biologic assignment (p < 0.001). On PROMIS-57 surveys there was decreased fatigue (p=0.003) and an increased ability to participate in social roles and activities (p=0.003) on the Donor Arm 2-years after biologic assignment. Differences in other secondary outcomes did not reach statistical significance. Barriers to accrual prevented an objective comparison of survival. Assignment to the Donor Arm led to improvements in VOC, fatigue, and social function.

Therapy concepts in type 1 diabetes mellitus treatment: disease modifying versus curative approaches.

For many autoimmune diseases, including type 1 diabetes mellitus (T1DM), efforts have been made to modify the disease process through pharmacotherapy. The ultimate goal must be to develop therapies with curative potential by achieving an organ without signs of parenchymal cell destruction and without signs of immune cell infiltration. In the case of the pancreas, this means regenerated and well-preserved beta cells in the islets without activated infiltrating immune cells. Recent research has opened up the prospect of successful antibody combination therapy for autoimmune diabetes with curative potential. This goal cannot be achieved with monotherapies. The requirements for the implementation of such a therapy with curative potential for the benefit of patients with T1DM and LADA (latent autoimmune diabetes in adults) are considered.

Molecular interactions of plant-derived inhibitors from Euphorbia hirta against binding sites of HPV E6 and E7 oncoproteins - An in-silico analysis

Although no cure for Human Papilloma virus (HPV) exists at the moment, effective vaccines are present that can prevent the most harmful strains of the virus from infecting people. While potential cures like therapeutic vaccines, immunotherapy, and gene therapy are still in the early stages of development and may take years to become widely available, we focussed on using traditional Siddha-based medicines (phytochemicals of Euphorbia hirta L.) as a prospect through in-silico docking studies. Twelve phytochemicals from Euphorbia hirta L. were selected to investigate the antiviral properties against HPV. These ligand structures were obtained from PubChem database, prepared for docking with two major HPV targets i.e., E6 and E7 oncoproteins obtained from PDB, using AutoDock tools. The analysis revealed the potential of lobeline and euphol ligands effectively binding to the active sites of E6 and E7 proteins respectively. Using the ADMET lab 2.0 server, the ligands were evaluated for their commercial drug potential by considering their absorption, distribution, metabolism, excretion, and toxicity properties.

Synthesis and antifungal activity of novel piperidinyl thiazole derivatives.

As an investigative program around the development of novel oomycetes fungicides, a systematic exploration of piperidinyl thiazole fungicides employing a bioisosteric replacement strategy was planned. A series of novel piperidinyl thiazole analogues were designed, synthesised, and evaluated as fungicides in vitro and in vivo against three oomycete fungal pathogens: Phytophthora infestans (P. infestans), Plasmopara viticola (P. viticola), and Pseudoperonospora cubensis (P. cubensis). Variation at four different regions of piperidinyl thiazole fungicides like Oxathiapiprolin and Fluoxapiprolin was considered. All variations delivered excellent in vitro and in vivo activity against P. infestans at extremely low concentrations. O-linked heterocyles, bicyclic piperidines, and sulfoximine-substituted aryls demonstrated the most robust transfer of in vitro activity into the greenhouse, while pyridones, acylated sulfoximines, and sultams showed less consistent results concerning the transfer. Specific compounds were selected for deeper evaluation of oomycetes activity. Several of them with representatives of all the series showed an excellent in vivo activity against P. viticola and P. cubensis. Among the most active compounds, P14 and P25 were further profiled in advanced studies and were found to have a robust curative potential. P14, P15, and P25 provided excellent control of P. infestans (in potato), P. viticola (in grapes), and P. cubensis (in cucumber) in field trials at dose rates of 20 and 30 g per hectare. A bioisosteric replacement strategy was successfully employed to identify novel piperidine thiazole derivatives with robust and commercially interesting control of oomycetes diseases in the greenhouse and under field conditions. A systematic exploration of various modifications of the piperidine thiazole class and their structure activity relationships was described. © 2024 Society of Chemical Industry.

Hepatitis B

Hepatitis B is a viral infection caused by the Hepatitis B virus (HBV), primarily affecting the liver and leading to both acute and chronic disease. With over 250 million individuals suffering from chronic Hepatitis B, it poses a significant global health challenge, being a leading cause of liver cirrhosis, liver failure, and hepatocellular carcinoma. This study aims to elucidate the transmission pathways, treatment options, and necessary public health strategies for Hepatitis B. We analyze the modes of transmission, which include contact with infectious body fluids—primarily through perinatal transmission, unprotected sexual contact, and sharing contaminated needles. Despite the availability of an effective vaccine since the 1980s, Hepatitis B remains endemic in many parts of Asia and Africa due to limited immunization coverage. The pathogenesis of HBV involves complex interactions between the virus and the host immune system, potentially leading to liver inflammation and fibrosis. Clinical presentations vary widely, ranging from asymptomatic infections to severe liver disease. Current treatment options for chronic Hepatitis B include antiviral medications such as tenofovir and entecavir, which suppress viral replication but do not cure the infection. Recent advancements in therapeutic strategies, including novel antivirals and immune modulators, show promise for more effective management and potential cures in the future. Comprehensive public health strategies—such as vaccination, screening, and education—are crucial for controlling the spread of HBV and reducing the global burden of Hepatitis B-related complications.

Spinocerebellar ataxia type 7: A case report

Introduction: Spinocerebellar ataxia type 7 is part of a rare group of neurodegenerative diseases, characterized by lesions in the brainstem, cerebellum, spinal cord, and retina, manifesting as motor disturbances associated with signs of pyramidal involvement and amaurosis. The dysfunction is caused by autosomal dominant genetic alterations, with disease severity and the age of symptom onset being directly linked to the patient’s genetic expression. Case Report: We present the case of a 24-year-old woman, previously healthy, who denied smoking, drinking alcohol, or taking any other drugs. She reported that approximately nine months, she had experienced a decline in dexterity for tasks requiring fine motor skills. She also exhibited impaired gait, frequent falls, and difficulties in performing basic activities of daily living (ADLs). On neurological examination, she presented with an ataxic and staggering gait, tremor during movement, dysmetria, dysdiadochokinesia, movement decomposition, dysarthria (scanning speech), dysphagia, dystasia, dysbasia, and nystagmus, all of which are indicative of cerebellar impairment. A genetic panel revealed the presence of 44 cytosine-adenine-guanine nucleotide repeat expansions on allele 2 of the ATXN7 gene, confirming the diagnosis of spinocerebellar ataxia type 7. Conclusion: In this case report, the diagnosis of spinocerebellar ataxia was established through a comprehensive assessment of the patient’s clinical history, neurological examination, imaging studies, and genetic profiling, all of which are essential for reaching a definitive diagnosis. The prognosis for this disease varies due to ongoing research into its pathophysiology. Furthermore, discussions within the scientific community regarding potential cures for this condition continue

Optimizing cryopreservation strategies for scalable cell therapies: A comprehensive review with insights from iPSC-derived therapies.

Off-the-shelf cell therapies hold significant curative potential for conditions, such as Parkinson's disease and heart failure. However, these therapies face unique cryopreservation challenges, especially when novel routes of administration, such as intracerebral or epicardial injection, require cryopreservation media that are safe for direct post-thaw administration. Current practices often involve post-thaw washing to remove dimethyl sulfoxide (Me2SO), a cytotoxic cryoprotective agent, which complicates the development and clinical translation of off-the-shelf therapies. To overcome these obstacles, there is a critical need to explore Me2SO-free cryopreservation methods. While such methods typically yield suboptimal post-thaw viability with conventional slow-freeze protocols, optimizing freezing profiles offers a promising strategy to enhance their performance. This comprehensive review examines the latest advancements in cryopreservation techniques across various cell therapy platforms, with a specific case study of iPSC-derived therapies used to illustrate the scalability challenges. By identifying key thermodynamic and biochemical phenomena that occur during freezing, this review aims to identify cell-type independent approaches to improve the efficiency and efficacy of cryopreservation strategies, thereby supporting the widespread adoption and clinical success of off-the-shelf cell therapies.

Comparative efficacy of different exercise modalities on metabolic profiles and liver functions in non-alcoholic fatty liver disease: a network meta-analysis.

Research evidence suggests that exercise is a potent therapeutic strategy for non-alcoholic fatty liver disease (NAFLD). Many investigations have delved into the curative potential of diverse exercise regimens on NAFLD. This investigation synthesizes findings from randomized controlled trials via a network meta-analysis to evaluate the efficacy of exercise-based interventions on NAFLD. We conducted a search across five electronic databases (Web of Science, EMBASE, PubMed, SCOPUS, and CNKI)to identify randomized controlled trials (RCTs) comparing the effects of different exercise modalities on metabolic profiles and liver functions in patients with NAFLD. The literature search was comprehensive up to 15, December 2023. The selected studies were subjected to a rigorous quality appraisal and risk of bias analysis in accordance with the Cochrane Handbook's guidelines, version 5.1.0. We employed Stata/MP 17 for the network meta-analysis, presenting effect sizes as standardized mean differences (SMD). This study aggregated results from 28 studies, involving a total of 1,606 participants. The network meta-analysis revealed that aerobic exercise was the most effective intervention for improving BMI in patients with NAFLD, demonstrating a significant decrease in BMI (-0.72, 95%CI: -0.98 to -0.46; p < 0.05; Surface Under the Cumulative Ranking (SUCRA) = 79.8%). HIIT was the top intervention for enhancing HDL-C (0.12, 95% CI: 0.04 to 0.20; p < 0.05; SUCRA = 76.1%). Resistance exercise was the most effective for reducing LDL-C (-0.20, 95% CI: -0.33 to -0.06; p < 0.05; SUCRA = 69.7%). Mind-body exercise showed superior effectiveness in improving TC (-0.67, 95% CI: -1.10 to -0.24; p < 0.05; SUCRA = 89.7%), TG = -0.67, 95% CI: -1.10 to -0.24; p < 0.05; SUCRA = 99.6%), AST (-8.07, 95% CI: -12.88 to -3.25; p < 0.05; SUCRA = 76.1%), ALT (-12.56, 95% CI: -17.54 to -7.58; p < 0.05; SUCRA = 99.5%), and GGT (-13.77, 95% CI: -22.00 to -5.54; p < 0.05; SUCRA = 81.8%). This network meta-analysis demonstrates that exercise interventions positively affect various metabolic profiles and liver functions in NAFLD patients. Mind-body exercises are particularly effective, surpassing other exercise forms in improving metabolic profiles and liver functions. https://www.crd.york.ac.uk/PROSPERO/, identifier registration number CRD42024526332.

Unwrapping the immunological alterations in testicular germ cell tumors: From immune homeostasis to malignancy and emerging immunotherapies.

Testicular germ cell tumors (TGCTs), derived from primordial germ cells, are rare malignancies with high curative potential. However, the emergence of new evidence indicating that 15% of patients experience tumor progression, leading to death, underscores the need for innovative therapeutics. This review aimed to explore the immune status in maintaining testicular health and the immune-related aspects of malignancy. Furthermore, it presents an overview of current data on the use of immunotherapy for TGCT patients. Recent advances in immunology have opened a promising avenue for studying diseases and highlighted its role in treating diseases. While the immunopathological facets of TGCTs are not fully understood, investigations suggest a complex interplay among testis-resident immune cells, testis-specific cells (i.e., Sertoli cells (SCs) and Leydig cells (LCs)), and immune-regulating mediators (e.g., sex hormones) in the normal testicle that foster the testicular immune privilege (TIP). Although TIP plays a crucial role in sperm production, it also makes testis vulnerable to tumor development. In the context of cancer-related inflammation, disruption of TIP leads to an imbalanced immune response, resulting in chronic inflammation that can contribute to testicular tissue dysfunction or loss, potentially aiding in cancer invasion and progression. Comparing the immune profiles of normal and malignant testes is valuable and may provide insights into different aspects of testicular immunity and immune-based treatment approaches. For patients resistant to chemotherapy and with a poor prognosis, immunotherapy has shown promising results. However, its effectiveness in treating resistant TGCTs or preventing tumor recurrence is still uncertain.

Uncovering the pharmacological mechanisms of Patchouli essential oil for treating ulcerative colitis

Ethnopharmacological relevancePogostemonis Herba has long been used in traditional Chinese medicine to treat inflammatory disorders. Patchouli essential oil (PEO) is the primary component of Pogostemonis Herba, and it has been suggested to offer curative potential when applied to treat ulcerative colitis (UC). However, the pharmacological mechanisms of PEO for treating UC remain to be clarified. Aim of the studyTo elucidate the pharmacological mechanisms of PEO for treating UC. Methods and resultsIn the present study, transcriptomic and network pharmacology approaches were combined to clarify the mechanisms of PEO for treating UC. Our results reveal that rectal PEO administration in UC model mice significantly alleviated symptoms of UC. In addition, PEO effectively suppressed colonic inflammation and oxidative stress. Mechanistically, PEO can ameliorate UC mice by modulating gut microbiota, inhibiting inflammatory targets (OPTC, PTN, IFIT3, EGFR, and TLR4), and inhibiting the PI3K-AKT pathway. Next, the 11 potential bioactive components that play a role in PEO's anti-UC mechanism were identified, and the therapeutic efficacy of the pogostone (a bioactive component) in UC mice was partially validated. ConclusionThis study highlights the mechanisms through which PEO can treat UC, providing a rigorous scientific foundation for future efforts to develop and apply PEO for treating UC.
