ABSTRACT

Parkinson's disease (PD) is a complex neurological condition caused due to inheritance, environment, and behavior among various other parameters. The onset, diagnosis, course of therapy, and future of PD are thoroughly examined in this comprehensive review. This review also insights into pathogenic mechanisms of reactive microgliosis, Lewy bodies, and their functions in the evolution of PD. It addresses interaction complexity with genetic mutations, especially in genes such as UCH-L1, parkin, and α-synuclein, which illuminates changes in the manner dopaminergic cells handle proteins and use proteases. One of the emerging therapeutic routes that are being investigated is neuroprotective medicines that aim to prevent the aggregation of α-synuclein and interventions that modify the progression of diseases. The review concludes by stressing the dynamic nature of PD research and the potential game-changing impact of precision medicines on current approaches to therapy. This raises the improved outcomes and life quality for those with PD. Potential treatments for severe PD include new surgical methods like Deep Brain Stimulation (DBS). Further, exploration of non-motor manifestations, such as cognitive impairment, autonomic dysfunction, and others, is covered in this review article. These symptoms have a significant impact on patients' quality of life. One of the emerging therapeutic routes that are being investigated is neuroprotective medicines that aim to prevent the aggregation of α-synuclein and interventions that modify the progression of diseases. The review concludes by stressing the dynamic nature of PD research and the potential game-changing impact of precision medicines on current approaches to therapy.

ABSTRACT

Gastric cancer represents a significant global health challenge due to its high mortality and incidence rates, particularly in Eastern Asia, Eastern Europe, and South America. This comprehensive review synthesizes the latest epidemiological data and explores both modifiable and non-modifiable risk factors associated with gastric cancer, aiming to delineate the multifactorial etiology of this disease. Modifiable risk factors include Helicobacter pylori infection, obesity, dietary habits, smoking and alcohol consumption, whereas nonmodifiable factors comprise genetic predispositions, age, family history and male gender. The interplay of these factors significantly impacts the risk and progression of gastric cancer, suggesting potential preventive strategies. The challenges in treating gastric cancer are considerable, largely because of the late-stage diagnosis and the heterogeneity of the disease, which complicate effective treatment regimens. Current treatment strategies involve a combination of surgery, chemotherapy, radiotherapy, and targeted therapies. The FLOT regimen (5-FU, Leucovorin, Oxaliplatin and Docetaxel) is now a standard for resectable cases in Europe and the US, showing superior survival and response rates over ECF and ECX regimens. For HER2-positive gastric cancer, trastuzumab combined with chemotherapy improves overall survival, as demonstrated by the ToGA trial. Additionally, immune checkpoint inhibitors like pembrolizumab and nivolumab offer promising results. However, the five-year survival rate remains low, underscoring the urgency for improved therapeutic approaches. Recent advancements in molecular biology and cancer genomics have begun to pave the way for personalized medicine in gastric cancer care, focusing on molecular targeted therapies and immunotherapy. This review also highlights the critical need for better screening methods that could facilitate early detection and treatment, potentially improving the prognosis. By integrating epidemiological insights with new therapeutic strategies, this article aims to thoroughly understand of gastric cancer's dynamics and outline a framework for future research and clinical management, advocating for a multidisciplinary approach to tackle this formidable disease.

ABSTRACT

Medical data registers are a key instrument of medical care research and a valuable tool for medical quality assurance. The structured plausibility tested documentation of large case numbers on a longitudinally oriented time axis with different points in time of data acquisition enables statements to be made on numerous relevant outcomes, not only the mortality of patients. For incidents outside the daily routine care in trauma surgery, such as natural disasters, accidents with multiple casualties and nonmilitary treatment of the domestic population in defence situations, such registers can provide data-based recommendations for action. These data, mainly obtained from routine traumatological treatment, enable a targeted resource management in the abovenamed incidents, which are associated with mass casualties. Due to the utilization of registers from the military field or from international registers, the perspective is additionally extended with respect to treatment strategies and injury patterns. Whether data can also be generated in a suitable manner for the abovenamed registers in specific disaster situations and can provide a direct gain of knowledge from the incident, must be critically discussed. The maintenance of the register datasets is time-consuming and has been subjected to a more stringent regulation at least since May 2018, when the European Union General Data Protection Regulation (EU-GDPR) came into force. The future Register Act in Germany will hopefully achieve greater simplification in the documentation of routine data.

ABSTRACT

Non-coding RNAs (ncRNAs) are transcripts originating from the genome that do not serve as templates for protein synthesis. They function as epigenetic and translational regulators in various pathophysiological mechanisms, including cell proliferation and apoptosis. The ferroptosis signaling pathway, a novel mode of cell death, participates in numerous pathophysiological processes. Its signaling transmission is both complex and precise, featuring interconnected and interdependent pathways. Recent studies suggest that ncRNAs can finely regulate key genes in the ferroptosis pathway, thus modulating cellular functions, reducing oxidative stress, and maintaining maternal-fetal interface homeostasis. Future strategies targeting the ncRNA/ferroptosis axis may provide new perspectives and potential intervention points for treating preeclampsia. This article clarifies how the ncRNA/ferroptosis axis impacts preeclampsia, revealing how ncRNAs interact with ferroptosis, and pinpointing new molecular targets for the treatment of preeclampsia, thereby providing theoretical support for clinical strategies.

ABSTRACT

BACKGROUND: Patients with multiple chronic conditions, for example, musculoskeletal conditions and comorbidities, often receive inadequate and sometimes even contradictory care. Physiotherapists are well qualified to manage patients with musculoskeletal conditions and comorbidities due to their education and experience with rehabilitation; however, it is unknown which challenges they face when treating these patients. AIM: To identify challenges, treatment strategies, and delineations of areas of responsibility among physiotherapists working in private physiotherapy practice when treating people with musculoskeletal conditions and comorbidities. METHODS: Qualitative study using focus group discussions and participant observations of 13 physiotherapists working in Danish private physiotherapy clinics. Grounded theory was applied to guide the analysis. RESULTS: Two major themes emerged from the focus groups and the observations (1) The necessity of adapting management to the patients and their treatment trajectory; (2) The dilemma of overall responsibility for coordinating care. The physiotherapists described different elements of adapting their management, including being challenged on time, taking extra care of the patient, and having to adjust to a fluctuating course of treatment. The dilemma in coordinating care concerned whether the responsibility should lie with the physiotherapist, other healthcare professionals, or the patients, and whether to treat only the condition on the referral or to treat all the conditions the patient had. CONCLUSION: Physiotherapists use adapted strategies for diagnosing and treating patients with musculoskeletal conditions and comorbidities and are uncertain about the overall responsibility for coordinating care and whether they should focus on the index condition alone or also the other comorbidities the patient has.

ABSTRACT

Amid the dynamic field of cancer research, various targeted therapies have proven crucial in combating breast cancer, the most prevalent cancer among women globally. Triple Negative Breast Cancer (TNBC) stands out from other types of breast cancer due to the absence of three key receptors on the cell surface (progesterone, estrogen, and HER2). Researchers are working on finding ways to address TNBC's elusive biomarkers and minimize the damage caused by the disease through treatments like chemotherapies and targeted pathway receptors. One connection that should receive more attention is the link between TNBC and obesity. Obesity is defined as consuming significantly more energy than is expended, resulting in a high BMI. Moreover, obesity fosters a cancer-friendly environment characterized by inflammation, elevated levels of hormones, proteins, and signaling that activate pathways promoting cancer. Non-Hispanic black women have experienced notable disparities in TNBC rates. Various factors have led to the higher incidence and poorer outcomes of TNBC in non-Hispanic black women. This detailed review explores the complex relationship between obesity and TNBC, examining how the two disorders are connected in terms of disparities and offering a glimpse into future research and interventions.

ABSTRACT

Cases of sickle cell disease with dengue during pregnancy have rarely been reported. Sickle cell disorder is one of the most commonly inherited genetic disorders, especially in certain regions of India. Sickle cell disease, especially in pregnancy, has varying clinical severity, which may potentially lead to serious complications, negatively affecting the maternal and fetal outcomes. Dengue is commonly seen in tropical countries. Serotypes 1, 2, 3, and 4 of the dengue virus cause dengue, an infection spread by Aedes aegypti mosquitos. A 24-year-old primigravida with 36 weeks of gestation, with a known case of sickle cell disease and a history of multiple blood transfusions, presented to the emergency department with a history of fever for four days associated with body pains and chills. Her fever profile was sent, and the patient was diagnosed with dengue. She was treated with packed red cell transfusion and conservatively managed. She went into spontaneous preterm labour and delivered a healthy female child. Pregnancy-related pathophysiological changes, such as elevated blood volume, elevated metabolic demand, elevated blood viscosity, and hypercoagulability, combined with dengue fever complications, cause sickle cell disease patients to experience a higher rate of morbidity and mortality.

ABSTRACT

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers worldwide. Presently, only a fraction of patients undergo successful surgical resection, the most effective treatment. Enhancing treatment strategies necessitates a deep comprehension of the factors underlying extended survival after surgical resection in patients. METHODS: This study aims to identify the important factors of PDAC patients' long-term survival with metatranscriptomics and multiplex immunofluorescence (IF) staining analyses. Specifically, differences in tumor immune microenvironment (TIME) were investigated between treatment-naïve PDAC short-term survivors (STS, overall survival <6 months) and long-term survivors (LTS, overall survival >5 years). RESULTS: As a result, we detected 589 over-expressed genes, including HOXB9, CDA, and HOXB8, and 507 under-expressed genes, including AMY2B, SCARA5, and SLC2A2 in LTS. Most of the Reactome overbiological pathways enriched in our data were over-expressed in LTS, such as RHO GTPase Effectors and Cell Cycle Checkpoints. Eleven microbiomes significantly differed between LTS and STS, including Sphingopyxis and Capnocytophaga. Importantly, we demonstrate that the TIME profile with an increased abundance of memory B cells and the reduction of M0 and pro-tumoral M2 macrophages are associated with a good prognosis in PDAC. CONCLUSIONS: In this study, we delved into the TIME with metatranscriptomics and IF staining analyses to understand the prerequisite of prolonged survival in PDAC patients. In LTS, several biological pathways were overexpressed, and specific microbiomes were identified. Furthermore, apparent differences in driven immune factors were found that provide valuable insights into developing new treatment strategies.

ABSTRACT

Objective: The objective of this systematic review was to describe novel regimens and treatment strategies in neoadjuvant therapy for colorectal cancer (CRC). The aim was to summarize the current advancements in neoadjuvant chemotherapy (NACT) for CRC, including the use of cytotoxic drugs, targeted treatments, and immunotherapy. The analysis aimed to provide insights into the potential benefits and drawbacks of these novel approaches and highlight the need for further research to optimize NACT use in CRC and improve patient outcomes. Methods: From October 20, 2023, to December 10, 2023, a comprehensive literature search was conducted across multiple databases, including PubMed, Ovid, Web of Science, the Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Embase, and Scopus. Studies addressing the use of and treatment strategies for CRC and neoadjuvant therapies were included. Screening was conducted in two steps, initially by title and abstract and then by full-text articles. English-language articles were considered, while preprints, non-English publications, and articles published as grey literature were excluded from the study. A total of 85 studies were selected for further analysis after screening and filtering. Results: After filtering out duplicates and items that were irrelevant to our research query from the initial database search's 510 results, 397 unique articles were found. Eighty-five studies were chosen for additional analysis after the articles underwent two rounds of screening. Conclusion: The review concluded that neoadjuvant therapy for CRC has evolved beyond conventional approaches and holds promise for improving patient outcomes. Future prospects for advancing neoadjuvant approaches are promising, with ongoing clinical trials investigating the refinement of strategies, identification of predictive biomarkers, and optimization of patient selection. The adoption of novel regimens, precision medicine, and immunotherapy offers opportunities to redefine treatment paradigms and enhance patient care in CRC.

ABSTRACT

OPINION STATEMENT: Multiple myeloma (MM) is the second most common hematological malignant (HM) tumor, and a large proportion of patients still suffer from treatment failure and a poor prognosis despite the use of some newly approved drugs, a deeper understanding of the underlying mechanism is still needed. Ferroptosis is a new form of programmed cell death (PCD) that is different from other traditional forms of cell death such as apoptosis, necrosis and autophagy. With the continuous deepening of research on ferroptosis, ferroptosis has been found to be closely related to MM. This article reviews the regulatory mechanism of ferroptosis and research progress on ferroptosis in MM, providing a new theoretical basis and strategies for the diagnosis and treatment of MM.

ABSTRACT

This article reviews the mechanisms and prevention strategies associated with vitamin D and sarcopenia in older adults. As a geriatric syndrome, sarcopenia is defined by a notable decline in skeletal muscle mass and strength, which increases the risk of adverse health outcomes such as falls and fractures. Vitamin D, an essential fat-soluble vitamin, is pivotal in skeletal muscle health. It affects muscle function through various mechanisms, including regulating calcium and phosphorus metabolism, promoting muscle protein synthesis, and modulation of muscle cell proliferation and differentiation. A deficiency in vitamin D has been identified as a significant risk factor for the development of sarcopenia in older adults. Many studies have demonstrated that low serum vitamin D levels are significantly associated with an increased risk of sarcopenia. While there is inconsistency in the findings, most studies support the importance of vitamin D in maintaining skeletal muscle health. Vitamin D influences the onset and progression of sarcopenia through various pathways, including the promotion of muscle protein synthesis, the regulation of mitochondrial function, and the modulation of immune and inflammatory responses. Regarding the prevention and treatment of sarcopenia, a combination of nutritional, exercise, and pharmacological interventions is recommended. Further research should be conducted to elucidate the molecular mechanism of vitamin D in sarcopenia, to study genes related to sarcopenia, to perform large-scale clinical trials, to investigate special populations, and to examine the combined application of vitamin D with other nutrients or drugs. A comprehensive investigation of the interconnection between vitamin D and sarcopenia will furnish a novel scientific foundation and productive strategies for preventing and treating sarcopenia. This, in turn, will enhance the senior people's quality of life and health.

ABSTRACT

Multiple sclerosis (MS) is a heterogenous autoimmune-mediated disease of the central nervous system (CNS) characterized by inflammation, demyelination and chronic progressive neurodegeneration. Among its broad and unpredictable range of neuropsychiatric symptoms, behavioral changes are common, even from the early stages of the disease, while they are associated with cognitive deficits in advanced MS. According to DSM-5, behavioral disorders include attention deficits, oppositional, defiant and conduct disorders, anxiety, panic, obsessive-compulsive disorders (OCD), disruptive and emotional disorders, while others include also irritability, agitation, aggression and executive dysfunctions. Approximately 30 to 80% of individuals with MS demonstrate behavioral changes associated with disease progression. They are often combined with depression and other neuropsychiatric disorders, but usually not correlated with motor deficits, suggesting different pathomechanisms. These and other alterations contribute to disability in MS. While no specific neuropathological data for behavioral changes in MS are available, those in demyelination animal models share similarities with white matter and neuroinflammatory abnormalities in humans. Neuroimaging revealed prefrontal cortical atrophy, interhemispheric inhibition and disruption of fronto-striato-thalamic and frontoparietal networks. This indicates multi-regional patterns of cerebral disturbances within the MS pathology although their pathogenic mechanisms await further elucidation. Benefits of social, psychological, behavioral interventions and exercise were reported. Based on systematical analysis of PubMed, Google Scholar and Cochrane library, current epidemiological, clinical, neuroimaging and pathogenetic evidence are reviewed that may aid early identification of behavioral symptoms in MS, and promote new therapeutic targets and strategies.

ABSTRACT

Mucocles of the appendix, encompassing mucinous cystadenomas and mucinous cystadenocarcinomas, represent rare but clinically significant appendiceal lesions characterized by the accumulation of mucin within the appendix lumen. This review explores the diagnostic complexities and treatment strategies associated with mucocles, emphasizing the importance of its accurate recognition and management. Diagnostic challenges arise due to overlapping symptoms with acute appendicitis and other appendiceal pathologies, necessitating a multidimensional approach that includes imaging, histopathological analysis, and clinical correlation. Treatment options range from appendectomy for benign lesions to more extensive surgical procedures, such as right hemicolectomy for malignant forms. Prognostic factors, including histological subtype and tumor size, influence treatment decisions and long-term outcomes. By synthesizing current evidence and clinical insights, this review aims to provide a comprehensive framework for clinicians to navigate the complexities of mucocles of the appendix, offering perspectives that can guide effective management and future research endeavors.

ABSTRACT

Oral cancer remains a significant global health concern and its early detection plays a crucial role in improving patient outcomes. Identifying reliable prognostic markers is essential to guide treatment decisions and enhance survival rates. Fructose 1,6-bisphosphate aldolase (FBA), a glycolytic enzyme, has emerged as a promising candidate for prognostic assessment of oral cancer. This review highlights the role of FBA in tumorigenesis, its potential utility in predicting disease progression and patient survival, and its influence on response to radiotherapy. Recent studies have suggested that dysregulated metabolic pathways involving FBA may contribute to radiation resistance in oral cancer, emphasizing the need for further exploration of FBA-targeted therapeutic strategies. Understanding the role of FBA in oral cancer pathogenesis could pave the way for the development of personalized treatment strategies, including combined radiotherapy.

ABSTRACT

OBJECTIVE: We assessed the effectiveness of a treatment strategy based on hematoma characteristics and volume. METHODS: From September 2022 to December 2023 (the Study period), a 2-center retrospective observational study of initial chronic subdural hematoma was performed. The baseline period was from January 2018 to December 2019. Patients were classified into the high and low retreatment rate groups (Groups H and L, respectively). During the Study period, Group H was treated with drainage and middle meningeal artery embolization, while Group L was treated with drainage or middle meningeal artery embolization alone. During the Baseline period, all the patients were treated with drainage alone. The primary and secondary endpoints were group retreatment rates and severe procedure-related complications requiring surgical intervention and permanent sequelae, respectively. RESULTS: Fifty-two patients were included during the Study period (31 in Group H and 21 in Group L) and 53 during the Baseline period (32 in Group H and 21 in Group L). Three (5.8%) and 9 (17.0%) patients required retreatment in the Study and Baseline periods, respectively (P = 0.12). One (3.2%) and 9 (28.1%) patients in Group H required retreatment during the Study and Baseline periods, respectively (P = 0.01). Similarly, 2 patients (9.5%) and no patient in Group L required retreatment during the Study and Baseline periods, respectively (P = 0.49). No severe complications were reported throughout. CONCLUSIONS: Chronic subdural hematoma treatment strategies that consider to hematoma volume and characteristics have the potential to identify and reduce treatment rates in cases with high retreatment rates.

ABSTRACT

Secondary BRAF variations have been identified as a mechanism of resistance to tyrosine kinase inhibitors (TKIs) in patients with driver gene-positive NSCLC. Nevertheless, there is still a lack of consensus regarding the characteristics and subsequent treatment strategies for these patients. We retrospectively reviewed the medical records of patients with driver gene-positive NSCLC who received TKIs therapy at Zhejiang Cancer Hospital between May 2016 and December 2023. The clinical and genetic characteristics of these patients were assessed, along with the impact of various treatment strategies on survival. This study enrolled 27 patients with advanced NSCLC, in whom BRAF variations occurred at a median time of 28 months after the initiation of targeted therapy. The multivariate accelerated failure time (AFT) model revealed that, compared to chemotherapy-based regimens group, the combined targeted therapy group (p < 0.001) and the combined local treatment group for oligo-progression (p < 0.001) significantly extended patient survival. In contrast, continuing the original signaling pathway's targeted monotherapy was associated with shorter survival (p = 0.034). The median global OS for each treatment group was as follows: chemotherapy-based regimens group, 45 months; combined targeted therapy group, 59 months; combined local treatment group for patients with oligo-progression, 46 months; and targeted monotherapy group, 36 months. Study results indicate that the combination targeted therapy group (including TKIs, BRAF inhibitors, and/or MEK inhibitors) and the localized treatment group are more effective than traditional chemotherapy-based regimens in improving survival. Additionally, continuing targeted monotherapy along the original signaling pathway proves less effective than chemotherapy-based regimens.
