Promise and challenges of traditional Chinese medicine, specifically Calculus bovis, in liver cancer treatment.

Liver cancer, one of the most common malignancies worldwide, ranks sixth in incidence and third in mortality. Liver cancer treatment options are diverse, including surgical resection, liver transplantation, percutaneous ablation, transarterial chemoembolization, radiotherapy, chemotherapy, targeted therapy, immunotherapy, and traditional Chinese medicine (TCM). A multidisciplinary team (MDT) is essential to customize treatment plans based on tumor staging, liver function, and performance status (PS), ensuring individualized patient care. Treatment decisions require a MDT to tailor strategies based on tumor staging, liver function, and PS, ensuring personalized care. The approval of new first-line and second-line drugs and the establishment of standard treatments based on immune checkpoint inhibitors have significantly expanded treatment options for advanced liver cancer, improving overall prognosis. However, many patients do not respond effectively to these treatments and ultimately succumb to the disease. Modern oncology treatments, while extending patient survival, often come with severe side effects, resistance, and damage to the body, negatively impacting quality of life. Huang et al's study published at World Journal of Gastroenterology rigorously validates the anticancer properties of Calculus bovis, enhancing our understanding of TCM and contributing to new liver cancer treatment strategies. For over 5000 years, TCM has been used in East Asian countries like China to treat various diseases, including liver conditions. Analysis of real-world clinical data suggests that for patients with advanced-stage tumors lacking effective treatments, integrated TCM therapies could provide significant breakthroughs.

Classic Hodgkin Lymphoma: An Illustrative Review of Select Diagnostic Limitations and Immunomorphological Challenges.

The diagnosis of classic Hodgkin lymphoma (CHL) in clinical practice remains reliant on tissue morphological and immunohistochemical evaluation. In this article, we illustrate specific scenarios that we have encountered in our clinical practice pertaining to diagnostic challenges in CHL. We begin with select presentations of morphologic variants of CHL and then discuss certain immunophenotypic deviations from what is deemed "normal patterns" of antigen expression by HRS cells. Lastly, we discuss mimickers of HRS cells, in lymphomatous and non-lymphomatous conditions.

Medication adherence in geriatric patients attending medical outpatient department.

BACKGROUND:  Adherence to medication represents a challenge in managing chronic conditions in the geriatric population. This study assessed adherence rates and factors affecting adherence of geriatric patients attending the Helen Joseph Hospital outpatient department. METHODS:  This was a prospective cross-sectional study of 130 patients aged 65 years and older, with at least two chronic conditions. Participants were administered a survey incorporating the Medication Adherence Rating Scale and the Adherence Barrier Questionnaire to identify medication adherence and patient-specific barriers to adherence, respectively. These instruments are reliable and valid. RESULTS:  Descriptive statistics and logistic regression were used for analysis. Most patients were female (63%) with a mean age of 72 (67-78) years. Common comorbidities included type 2 diabetes mellitus (63%), hypertension (98%), dyslipidaemia (92%) and congestive cardiac failure (38%). Polypharmacy was prevalent, affecting 53% of the participants. Despite 96% of participants being adherent, all had at least one barrier to adherence, with the majority (65%) having more than one barrier. The main barriers were forgetfulness (59%), fear of side effects (39%), problems with taking the medications (26%) and believing medications are poisonous (22%). Although most participants accessed the pharmacy easily, only 83% reported consistent medication availability and 11% could not afford to collect their medication. CONCLUSION:  Polypharmacy is common in the population. Despite high adherence rates, barriers such as believing medications are poisonous remain significant. A good patient-doctor relationship improves adherence.Contribution: Understanding the barriers to adherence in older adults with polypharmacy and multimorbidity can assist practitioners improve patient care.

Navigating the challenging storms of cancer management in a national cancer centre: perspectives of female patients.

BACKGROUND: Breast, cervical, and ovarian cancers are among the top ten global cancers, affecting women, with age-standardized rates per 100,000 being 47.8 for breast, 13.3 for cervical, and 6.6 for ovarian cancer. The journey from cancer symptoms, through diagnosis and treatment, to survivorship, presents numerous challenges. These challenges encompass physical, psychological, and social aspects, significantly impacting patients' quality of life. It is crucial for research to explore not only the challenges faced by patients but also the strategies they employ to cope with these obstacles. METHODS: This study employed a cross-sectional qualitative approach. Twenty respondents, aged between 15 and 45 years and had been diagnosed with a reproductive cancer (breast, ovarian, or cervical), and were either undergoing treatment or had completed treatment within one year of the study period were purposively selected. Respondents were interviewed using a semi-structured interview guide. A thematic analysis was conducted on twenty in-depth interviews (IDIs) to understand the challenges and support systems for cancer patients. RESULTS: The study identified two principal themes: the challenges faced by patients and the available support systems. The findings are based on patient narratives regarding the obstacles encountered during diagnosis, treatment, and follow-up, along with the mitigation strategies employed. Patients reported a range of challenges, categorized into financial and non-financial. Prominent among the non-financial challenges were psychological distress, body image issues, reduced sexual drive, and overall health deterioration. Support was primarily found through personal relationships and religious or spiritual beliefs. CONCLUSION: The research highlights the extensive psychological and social effects of cancer and it's treatment. The study revealed the intertwined nature of financial difficulties and non-financial challenges, emphasizing the importance of social support, including religious, family, healthcare, and peer support. The findings suggest that a comprehensive, multidisciplinary management plan which encompasses both medical and supportive care is required to enhance patient well-being.

Challenges and Outlooks in Precision Medicine: Expectations Versus Reality.

Recent developments in technology have led to rapid advances in precision medicine, especially due to the rise of next-generation sequencing and molecular profiling. These technological advances have led to rapid advances in research, including increased tumor subtype resolution, new therapeutic agents, and mechanistic insights. Certain therapies have even been approved for molecular biomarkers across histopathological diagnoses; however, translation of research findings to the clinic still faces a number of challenges. In this review, the authors discuss several key challenges to the clinical integration of precision medicine, including the blood-brain barrier, both a lack and excess of molecular targets, and tumor heterogeneity/escape from therapy. They also highlight a few key efforts to address these challenges, including new frontiers in drug delivery, a rapidly expanding treatment repertoire, and improvements in active response monitoring. With continued improvements and developments, the authors anticipate that precision medicine will increasingly become the gold standard for clinical care.

Loading bioactive peptides within different nanocarriers to enhance their functionality and bioavailability; in vitro and in vivo studies.

A hydrolyzed protein is a blend of peptides and amino acids which is the result of hydrolysis by enzymes, acids or alkalis. The Bioactive Peptides (BPs) show important biological roles including antioxidant, antimicrobial, anti-diabetic, anti-cancer, and anti-hypertensive effects, as well as positive effects on the immune, nervous, and digestive systems. Despite the benefits of BPs, challenges such as undesired organoleptic properties, solubility profile, chemical instability, and low bioavailability limit their use in functional food formulations and dietary supplements. Nanocarriers have emerged as a promising solution for overcoming these challenges by improving the stability, solubility, resistance to gastric digestion, and bioavailability, allowing for the targeted and controlled delivery, and reduction or masking of the undesirable flavor of BPs. This study reviews the recent scientific accomplishments concerning the loading of BPs into various nanocarriers including lipid, carbohydrate and protein based-nanocarriers. A special emphasis is given to their application in food formulations in accordance to the challenges associated with their use.

Allogeneic CAR-T cells for cancer immunotherapy.

Autologous chimeric antigen receptor (CAR)-modified T (CAR-T) cell therapy has displayed high efficacy in the treatment of hematological malignancies. Up to now, 11 autologous CAR-T cell products have been approved for the management of malignancies globally. However, the application of autologous CAR-T cell therapy has many individual limitations, long time-consuming, highly cost, and the risk of manufacturing failure. Indeed, some patients would not benefit from autologous CAR-T cell products because of rapid disease progression. Allogeneic CAR-T cells especially universal CAR-T (U-CAR-T) cell therapy are superior to these challenges of autologous CAR-T cells. In this review, we describe basic study and clinical trials of U-CAR-T cell therapeutic methods for malignancies. In addition, we summarize the problems encountered and potential solutions.

Complex ovarian masses: Diagnostic processes and outcomes in a clinical case series of benign tumors.

This case series explores the diagnostic and management complexities of non-malignant ovarian masses, illustrated through three distinct cases: struma ovarii, mature teratoma, and ovarian mass with peritoneal splenosis. The first case details a struma ovarii initially misinterpreted as a potential malignancy due to its complex imaging features, leading to diagnostic uncertainty. The second case involves a mature teratoma, which, despite typical imaging characteristics, presented significant symptoms that necessitated careful clinical management. The third case highlights an ovarian mass with peritoneal splenosis, a condition often mistaken for metastatic disease, underscoring the need for differential diagnosis, particularly in patients with a history of splenic trauma or surgery. These cases emphasize the importance of a comprehensive diagnostic approach that integrates detailed imaging, surgical findings, and histopathological examination to accurately distinguish between benign and malignant ovarian masses and inform appropriate management strategies.

Diagnostic Complexities and Management of Gouty Arthritis With Suspected Seronegative Rheumatoid Arthritis and Malignancy in an Elderly Male.

Rheumatoid arthritis (RA) and gout are two distinct types of inflammatory arthritis with significant morbidity. While RA is characterized by autoimmune synovitis, gout is defined by the deposition of urate crystals. Diagnosing these conditions becomes particularly challenging in patients with negative serological markers for RA, compounded by the patient's advanced age and potential for malignancy. This case involves a 77-year-old male with chronic gout, hypertension, chronic atrial fibrillation on edoxaban, diastolic congestive heart failure, and chronic kidney disease stage 3B, presenting with left knee pain and limited mobility. Despite negative serology for RA (rheumatoid factor (RF) <20.0 IU/ml, anti-CCP2 antibodies 1.2 U/mL), the clinical presentation raised suspicion for RA. Imaging revealed significant synovial hypertrophy and multiple periarticular lesions suggestive of chronic gouty tophi rather than RA or malignancy. The patient was managed with allopurinol, prednisolone, and colchicine and referred to rheumatology for further evaluation. Approximately 30% of RA patients may present with negative serological markers, complicating the diagnosis. Differentiating RA from gout is crucial due to differences in management strategies. Imaging modalities such as MRI and CT are essential in identifying characteristic changes of both conditions, such as synovial hypertrophy in RA and tophi in gout. In elderly patients, the possibility of malignancy should also be considered. This case highlights the complexity of diagnosing gouty arthritis mimicking seronegative RA, especially in elderly patients where the risk of malignancy must be considered. It underscores the need for comprehensive clinical and imaging evaluations and personalized treatment plans in managing patients with multiple comorbidities.

A Rare Case of Intravascular Lobular Capillary Hemangioma Mimicking a Testicular Tumor: Diagnostic Challenges.

Intravascular lobular capillary hemangioma (ILCH), also known as intravenous pyogenic granuloma, is a benign vascular lesion with a distinctive lobular arrangement of capillaries. It is typically confined to the head, neck, and upper extremities, and its occurrence in the testicular region is exceedingly rare. Here, we present a case of a 68-year-old male who was initially diagnosed with a testicular tumor based on imaging studies but was later found to have an ILCH located in the epididymis. This case underscores the diagnostic challenges posed by this rare entity due to its unusual presentation and mimicking of malignant conditions.

Disseminated peritoneal leiomyomatosis: A benign condition with diagnostic and therapeutic challenges.

Background: Disseminated peritoneal leiomyomatosis (DPL) is a variant of parasitic leiomyomas that is characterized by multiple peritoneal and subperitoneal nodules of proliferating smooth muscle cells that histologically resemble uterine leiomyoma. We report a case of recurrent DPL to highlight its diagnostic and therapeutic challenges at the Federal Medical Centre, Keffi, Nigeria. Case Report: The patient is a 25-year-old woman with a previous history of myomectomy 3 years before presentation to the hematology unit on account of abdominal lymphoma. Based on the working diagnosis, she was referred to the general surgery unit for an open biopsy and cytoreductive surgery. She was explored, and intraoperative findings were in keeping with multiple well-circumscribed intra-abdominal masses of varying sizes. The multiple and widespread locations of the masses precluded the complete removal of the masses. Four months post-surgery, she presented with similar lesions and had a repeat laparotomy. At the surgery, she had a total abdominal hysterectomy with bilateral salpingophorectomy and excision of the abdominal masses. She was then placed on letrozole, which prevented further tumor growth and abated her symptoms. Discussion: DPL is often rarely diagnosed preoperatively and thus poses a diagnostic challenge, with many cases asymptomatic and therapeutic challenges due to its tendency to recur. Its management currently lacks consensus and is often determined by many factors, such as the age of the patients, the number of nodules, and the desire to have more children, among others. Surgical excision combined with hormonal therapy is recommended for patients who wish to conceive. For postmenopausal women and those who no longer desire conception, total abdominal hysterectomy with bilateral salpingo-oophorectomy should be considered to prevent recurrence. Conclusion: DPL is a rare form of multiple extrauterine leiomyomas. We report a case of DPL in a woman that was managed with surgical intervention and hormonal manipulation therapy following the failure of the initial surgical excision alone. We thus suggest a combination of surgical intervention and postoperative hormonal manipulation in its management, as such a multi-modality of therapy was employed in the index case without evidence of recurrence after a year post-surgery.

Hookworm vaccines: current and future directions.

INTRODUCTION: Hookworms infect about half a billion people worldwide and are responsible for the loss of more than two billion disability-adjusted life years. Mass drug administration (MDA) is the most popular preventive approach, but it does not prevent reinfection. An effective vaccine would be a major public health tool in hookworm-endemic areas. AREAS COVERED: We highlight recent human studies where vaccination with irradiated larvae and repeated rounds of infection-treatment have induced partial protection. These studies have emphasized the importance of targeting the infective larvae to generate immunity to prevent adult worms from maturing in the gut. We summarize the current status of human and animal model vaccine trials. EXPERT OPINION: Hookworm infection is endemic in resource-poor developing regions where polyparasitism is common, and vaccine cold chain logistics are complex. Humans do not develop sterile immunity to hookworms, and the elderly are frequently overlooked in MDA campaigns. For all these reasons, a vaccine is essential to create long-lasting protection. The lack of a robust animal model to mimic human hookworm infections is a barrier to the discovery and development of a vaccine, however, there have been major recent advances in human challenge studies which will accelerate the process.

Recent advances and current status of gene therapy for epilepsy.

BACKGROUND: Epilepsy is a common neurological disorder with complex pathogenic mechanisms, and refractory epilepsy often lacks effective treatments. Gene therapy is a promising therapeutic option, with various preclinical experiments achieving positive results, some of which have progressed to clinical studies. DATA SOURCES: This narrative review was conducted by searching for papers published in PubMed/MEDLINE with the following single and/or combination keywords: epilepsy, children, neurodevelopmental disorders, genetics, gene therapy, vectors, transgenes, receptors, ion channels, micro RNAs (miRNAs), clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas)9 (CRISPR/Cas9), expression regulation, optogenetics, chemical genetics, mitochondrial epilepsy, challenges, ethics, and disease models. RESULTS: Currently, gene therapy research in epilepsy primarily focuses on symptoms attenuation mediated by viral vectors such as adeno-associated virus and other types. Advances in gene therapy technologies, such as CRISPR/Cas9, have provided a new direction for epilepsy treatment. However, the clinical application still faces several challenges, including issues related to vectors, models, expression controllability, and ethical considerations. CONCLUSIONS: Here, we summarize the relevant research and clinical advances in gene therapy for epilepsy and outline the challenges facing its clinical application. In addition to the shortcomings inherent in gene therapy components, the reconfiguration of excitatory and inhibitory properties in epilepsy treatment is a delicate process. On-demand, cell-autonomous treatments and multidisciplinary collaborations may be crucial in addressing these issues. Understanding gene therapy for epilepsy will help clinicians gain a clearer perception of the research progress and challenges, guiding the design of future clinical protocols and research decisions.

Determinants of Low Coverage of the Free Surgical Care Programme for Trachomatous Trichiasis in Rural Guinea in 2022.

This study aimed to describe the experiences of healthcare personnel and patients in the organization of free surgical campaigns and care for trachomatous trichiasis in the health district of Siguiri in Guinea, including challenges experienced in providing surgical care. This was an explanatory qualitative study conducted in 2022 in the health district of Siguiri. A total of 20 participants were interviewed including patients (n = 7; 35%), community health workers (n = 4; 20%), health services managers, and healthcare providers (n = 8; 40%). Two main data collection technics were used: documentary review and in-depth individual interviews. All interviews were transcribed and manually coded using an Excel extraction spreadsheet. Data were analysed using inductive and deductive approaches. The results showed several organizational, structural, and community challenges that underlined the low surgical coverage of trachomatous trichiasis in the health district of Siguiri. Organizational challenges included the low involvement of local actors in planning activities, the limited timeframe of the campaigns, and the lack of logistics for activities supervision and patients' transportation to surgery sites. Structural challenges included the inadequacy of health centres to provide surgical services, poor health infrastructures, and sanitation conditions in some areas. Individual challenges included remoteness of surgical sites and costs associated with services provision including medicines. Community challenges included fear of surgery and the coincidence of the campaigns with agricultural and mining activities. The results of the study call on the national neglected tropical disease program and its partners to adopt and promote micro-planning of trachomatous trichiasis surgical activities, with the effective participation of local stakeholders in endemic health districts. They should also envision integrating the management of surgical treatment including costs associated with care (transportation, food, rehabilitation support for patients who have undergone surgery) and complications of surgical procedures for an expansion of the trachomatous trichiasis free surgical care coverage in endemic health districts in Guinea.

Management of Giant Thyroid Tumors in Patients with Multiple Comorbidities in a Tertiary Head and Neck Surgery Center.

Background/Objectives: The thyroid gland can represent the seat of development for giant tumors exceeding 10 cm in diameter. A retrospective analysis on 21 cases of giant thyroid tumors with comorbidities, operated in the ENT Department of the Bucharest University Emergency Hospital has been conducted. Methods: Giant benign tumors accounted for 28.57% of the cases studied and reached gigantic volumes in an average time interval of 3 years, with an average resection piece weight of 318 g. Malignant tumors accounted for 71.43%, with an average duration of evolution of 7 years, with an average resection piece weight of 581 g. Results: Dysphagia was present in all patients, dyspnea in 47.61% and dysphonia in 38.09% of cases. Total thyroidectomy is the gold standard in giant thyroid tumors, associated with radical neck dissection, extended to groups VI and VII in malignant tumors. In 10 of 11 cases of giant malignant thyroid tumors (90.90%), without anaplastic thyroid carcinoma, the survival at 5 years after multimodal oncologic treatment was favorable. Anticoagulant treatment increased the risk of postoperative reversible recurrent laryngeal nerve lesion. Conclusions: The management of giant thyroid tumors in patients with multiple comorbidities needs a multidisciplinary team including endocrinologist, radiologist, anesthesiologist, pathologist, ENT surgeon, thoracic surgeon, oncologist and radiotherapist.

The Clinical and Molecular Landscape of Rosette-Forming Glioneuronal Tumors.

BACKGROUND: Rosette-Forming Glioneuronal Tumors (RGNTs) are rare, typically benign central nervous system tumors primarily located in the fourth ventricle and pineal region. Despite being classified as WHO grade I with generally favorable prognoses, RGNTs present complexities in their molecular mechanisms, occasional malignant transformation, and epidemiological characteristics that require further investigation. METHOD: This study systematically reviews the existing literature to analyze the epidemiological patterns, MRI characteristics, pathological features, diagnostic challenges, and molecular mechanisms associated with RGNTs, aiming to provide a comprehensive theoretical foundation for clinical practice and future research. RESULTS: Through an in-depth review of recent studies, key molecular mechanisms, including mutations in FGFR1, PIK3CA, TERT, and IDH1/2, are highlighted. Additionally, the challenges in accurate diagnosis and the potential for misdiagnosis are discussed, emphasizing the importance of thorough molecular analysis in clinical settings. The literature indicates that RGNTs predominantly affect young adults and adolescents, with a slight female predominance. MRI typically reveals mixed cystic-solid lesions, often accompanied by hydrocephalus. Pathologically, RGNTs are characterized by a combination of neuronal and glial components, with immunohistochemical staining showing positivity for Synaptophysin and GFAP. High frequencies of FGFR1 and PIK3CA mutations underscore the significance of these pathways in RGNT pathogenesis and progression. Although RGNTs generally exhibit low malignancy, the TERT mutations identified in some cases suggest a risk of malignant transformation. CONCLUSIONS: This study concludes that while current treatment strategies focus on surgical resection, integrating molecular diagnostics and targeted therapies may be essential for managing recurrent or refractory RGNTs. Future research should explore the impact of various gene mutations on tumor behavior and their correlation with clinical outcomes, to optimize individualized therapeutic strategies and improve patient survival and quality of life.
