Minimal Residual Disease as an Early Endpoint for Accelerated Drug Approval in Myeloma: A Roadmap.

Improvements in multiple myeloma (MM) treatments have extended patient survival to a decade or more. Treatment response rates >90% have introduced new challenges for drug development, including a need for early endpoints with greater sensitivity. The FDA, based on data from two academic research groups and industry, evaluated minimal residual disease (MRD) negativity as an intermediate endpoint for progression-free and overall survival, culminating in a unanimous vote by the Oncology Drugs Advisory Committee in April 2024 supporting MRD-negative complete response as an early endpoint reasonably likely to predict clinical benefit in MM that may be used to support accelerated approval.

Blood based immune biomarkers associated with clinical frailty scale in older patients with melanoma receiving checkpoint inhibitor immunotherapy

IntroductionImmunotherapy with checkpoint inhibition (ICI) is increasingly prescribed to older patients with cancer. High age, especially in combination with frailty, has been associated to immune senescence, which is the age-related decline in immune function, thereby possibly hindering ICI effectiveness. This cross-sectional study aimed to assess whether blood cell immune senescence markers are associated with age, frailty and response to anti-PD-1 treatment in older patients with metastatic melanoma.MethodsIn a prospective observational study, sixty patients with stage IIIC or IV melanoma undergoing anti-PD1 treatment were categorized into young (< 65 years; n = 22), old (> 65 years) without frailty (n = 19), and old with frailty (n = 19). In-depth immune cell phenotyping was performed in baseline blood samples (prior to treatment) using multispectral flow cytometry and compared between groups and with immunotherapy treatment response. Antigen-presenting cell capacity was evaluated using mixed lymphocyte reaction and T cell proliferative potential was assessed using PHA proliferation assay.ResultsNo significant differences in treatment response rates were observed across age groups. Older patients, irrespective of frailty, showed lower levels of naïve CD8 + T cells, with the old and frail group also exhibiting reduced tissue-resident effector memory CD8 + T cells and CD8 + mucosal associated invariant T (MAIT) cells. These differences were not associated with treatment outcomes. T cell proliferation and antigen-presenting cell capacities did not differ across groups.ConclusionSeveral ageing and frailty associated changes were detected among circulating immune cells in blood but were not associated with response to immunotherapy in our study. While these findings suggest that the level of frailty and ageing may not necessarily preclude the efficacy of ICI therapy, further investigation is needed to fully understand the impact of frailty and ageing on immunotherapy.

QLTI-20. BRIDGING THE GAP: UNDERSTANDING THE CURRENT TREATMENT RESPONSES TO ENHANCE THE STANDARD OF CARE AND OUTCOMES FOR MALIGNANT PERIPHERAL NERVE SHEATH TUMORS

Abstract Malignant peripheral nerve sheath tumor (MPNST) are a rare and aggressive cancer that make up 5-10% of all sarcomas. There is currently no effective targeted therapy to treat MPNST and surgical resection remains the mainstay of treatment, though often not feasible due to location, size of the tumor, or presence of metastases. Evaluation of MPNST treatment response to palliative chemotherapy regimens could serve as a reference point for target response rates in clinical trials going forward. We performed a retrospective electronic health record analysis of patients with biopsy-proven diagnoses of MPNST at Washington University and Johns Hopkins University. We evaluated tumor characteristics along with treatment response, overall survival (OS), and progression free survival (PFS) rates for different chemotherapeutic regimens. The cohort comprises 140 patients, with ages at diagnosis ranging from 21 to 40 years. Most patients had tumors located in the extremities, with sizes ranging from 5-10 cm at the time of diagnosis. We identified 66 patients who received adjuvant chemotherapy, 44 received neoadjuvant chemotherapy and 28 did not receive any chemotherapy. We will present objective response rate (ORR) and clinical benefit rate (CBR) for neoadjuvant chemotherapy. Among patients with metastatic disease (n=53), 12 chemotherapy regimens were assessed. All regimens other than gemcitabine-docetaxel chemotherapy regimen performed better than the median PFS of 1.77 months which has been observed in clinical trials of targeted agents to date with the most compelling response to vincristine-irinotecan-temozolomide regimen. Despite advancements in our understanding of MPNST pathogenesis, these tumors carry a poor prognosis. Our study has identified several systemic therapies which should be further evaluated prospectively to improve treatment options and outcomes for patients with this aggressive sarcoma. These results can serve as a benchmark for future clinical trials.

Demographic Characteristics of Locally Advanced Laryngeal Cancer with Concurrent Chemo Radiotherapy along with Weekly Paclitaxel versus Weekly Cisplatin in Rajshahi Medical College

Modern multi-modality approaches using definitive concurrent chemoradiation has shown promising results in the treatment of locally advanced laryngeal cancer with intact cartilage and functional larynx. The aim of this study to estimate demographic Characteristics of Locally Advanced Laryngeal Cancer with Concurrent Chemo Radiotherapy along with Weekly Paclitaxel versus Weekly Cisplatin. This quasi-experimental study was conducted at the Department of Radiotherapy, Rajshahi Medical College Hospital, from January 2021 – June 2022 following ethical approval. Total 60 patients with locally advanced squamous cell carcinoma of larynx were included and divided into Arm-A (n=30) and Arm-B (n=30). After taking informed written consent, patients were given injection paclitaxel 30mg/m2 (Arm-A) or injection cisplatin 40mg/m2 (Arm-B) along with radiotherapy 66Gy in 33 fractions over 6.5 weeks. In this study, mean age of all study patients was 56.03±8.88 (SD) years with male predominance (88.3%). Demographic characteristics were similar across the two arms regarding age, gender, and tobacco history (p&gt;0.05). Treatment response was evaluated at 6, 12 and 24 weeks after the completion of treatment. In Arm- A 80.00% showed complete response whereas in Arm- B showed 70.00%. Partial response was 20.00% and 30.00% in Arm-A and Arm-B respectively. Both Arm-A and Arm-B had similar rate of treatment response at each follow up (p&gt;0.05).

Percutaneous radiofrequency ablation for stage B1 of modified Bolondi’s subclassification for intermediate-stage hepatocellular carcinoma

Abstract Background Hepatocellular carcinoma is considered the most common cause of hepatic focal lesions in Egypt. TACE is still the recommended treatment approach for patients in the intermediate stage. In the current research, we evaluated the safety and efficacy of percutaneous radiofrequency ablation (RFA) for a selected category in the intermediate stage (BCLC stage B). Methods This prospective study was conducted in the Department of Gastroenterology, Hepatology, Faculty of Medicine, Beni-Suef University between September 2022, and March 2024. In addition to AFP, Pelviabdominal ultrasound and computerized tomography (CT) were used for HCC diagnosis. According to the Child–Pugh score plus Milan and up-to-7 criteria, we used Modified Bolondi’s Subclassification (Kinki Criteria), to sub-classifies the BCLC B stage into B1/B2/B3 subcategories. Radiofrequency ablation was done in the interventional ultrasound unit. Treatment efficacy was assessed 6 months after tumor ablation. Results One hundred twenty participants were enrolled in our research trial, 72 (60%) were within the intermediate stage, and 48 (40%) had early-stage HCC. Most of our patients were males, 78 (65%). All the early-stage-HCC patients were Child–Pugh Score A (n = 48), while the intermediate-stage (BCLC B) group was classified in both Child–Pugh Score A (n = 59) and B (n = 16). Within the intermediate group (BCLC-stage B), All enrolled cases fell within category “B1” within the Kinki Criteria. Logistic regression analysis illustrated that the pre-treatment level of Platelet count and post-treatment level of AFP shows a statistically significant prediction effect on treatment response rate with p-value (0.028 and 0.007 respectively). Conclusion percutaneous radiofrequency ablation is considered an effective treatment option for the B1 subcategory according to Kinki Criteria for intermediate-stage HCC (BCLC-B1) but long-term follow-up is recommended.

Clinical characteristics and prognosis analysis of patients with IgG4-related hepatobiliary-pancreatic disease

Objective: To explore and analyze the clinical features of patients with immunoglobulin (Ig)G4-related hepatobiliary-pancreatic disease and the independent factors affecting the prognosis of IgG4-related sclerosing cholangitis (IgG4-SC). Methods: The clinical data of 179 adult cases diagnosed with IgG4-related hepato-pancreato-biliary disease in the Division of Gastroenterology and Hepatology, Renji Hospital, Shanghai Jiao Tong University School of Medicine from January 2011 to December 2022 were retrospectively analyzed. Patients were divided into three groups: isolated IgG4-SC, IgG4-SC/type 1 autoimmune pancreatitis(type 1 AIP), and isolated AIP according to the clinical manifestations. Demographic characteristics, baseline biochemical immunological indexes, and imaging manifestations were analyzed. The treatment response rate and survival rate were compared. The COX proportional hazards model was used to analyze the independent factors related to prognosis. Results: The mean age of diagnosis of patients with IgG4-related hepatobiliary-pancreatic disease was 60.3±12.0 years. Males accounted for 74.9%, and the median follow-up time was 38 months. The 1-year clinical response rate of patients with isolated IgG4-SC was lower than that of IgG4-SC/AIP (67.9% vs. 91.7%, P=0.019), and the primary endpoint-free 5-year survival rate was significantly reduced (64.9% vs. 95.9%, P<0.001). COX regression analysis showed that having cirrhosis before treatment (HR=6.708, P=0.004) and poor response after half a year of treatment (HR=11.488, P=0.002) were independent risk factors associated with the occurrence of adverse events in hepatobiliary diseases among patients with IgG4-SC. Conclusions: The clinical response rate and survival rate of patients with isolated IgG4-SC are lower than those of patients with IgG4-SC/AIP. Patients with IgG4-SC who do not respond well at six months of treatment and who have progressed to cirrhosis before treatment are at significantly increased risk of adverse events.

Response to tigilanol tiglate in dogs with mast cell tumors.

Information regarding response rate to tigilanol tiglate for mast cell tumors in dogs is limited. Report the response rate and durability of tigilanol tiglate intratumoral treatment in dogs with mast cell tumors presented to veterinary oncologists. One hundred forty-nine dogs; 151 individual tumors. Multicenter, retrospective survey-based study. Veterinary oncologists subscribed to the American College of Veterinary Internal Medicine (ACVIM) oncology listserv were solicited for information from dogs treated with tigilanol tiglate. An electronic survey was used to collect information at initial treatment, 1 month and 1 year after treatment. Most tumors were cutaneous, occurred on the limbs and were cytologically low grade. Seventy-five percent of dogs achieved a complete response after 1 dose of tigilanol tiglate 1 month after treatment. This response was durable at 1 year in 64% of dogs for which data were available (n = 88). Wound formation, an expectation after treatment, occurred after a median of 7 days (range, 1-91 days), with a median wound area of 4.71 cm2 (range, 0.09-100 cm2). Wounds took a median of 30 days to heal completely (range, 14-154 days). A moderate association between tumor volume and wound size was confirmed. Tigilanol tiglate is an effective local treatment option for mast cell tumors in dogs with a predictable clinical course and response. Because of the unique mode of action and clinical course, client education and careful case selection is necessary before electing tigilanol tiglate for local treatment.

Comparing the Efficacy of Intralesional Injection versus Systemic Steroids in Treating Idiopathic Granulomatous Mastitis: Insights from a Single-Center Experience

Objective: Idiopathic granulomatous mastitis (IGM) is a benign inflammatory condition predominantly affecting women of reproductive age, particularly those with a history of breastfeeding. Although the precise etiology remains unknown, treatment strategies continue to be a subject of debate. This study aimed to compare the efficacy of intralesional steroid (ILS) injections with oral steroid (OS) therapy in managing IGM. Materials and Methods: A total of 72 patients, clinically and histopathologically diagnosed with IGM, were treated with either ILSs (group ILS, n = 47) or OSs (group OS, n = 25) at a tertiary referral hospital between January 2022 and January 2024. The data were retrospectively analyzed. Results: The mean age of the patients was 33.5 years (range: 22–56). No statistically significant differences were observed between the two groups in terms of demographic characteristics, presenting symptoms, clinical findings, or laboratory results. The mean treatment duration was 6 months. There were no significant differences in treatment response or recurrence rates between the two groups. However, there was a statistically significant difference in the incidence of side effects, with 6.3% in the ILS group compared to 36% in the OS group (p = 0.001). Conclusion: Given its ease of application, lower incidence of side effects, and comparable efficacy, ILS injections may be considered a first-line treatment option in the management of IGM.

Mixed results for esmethadone in Phase 3 depression trial

A Phase 3 trial of esmethadone as adjunctive treatment for patients with treatment‐resistant depression did not meet its primary endpoint of significant improvement in depressive symptoms at 28 days compared with placebo. Esmethadone did show significant improvement over placebo in treatment response rate.

Functional Variation in Human CAZyme Genes in Relation to the Efficacy of a Carbohydrate-Restricted Diet in IBS Patients

Limiting the dietary intake of certain carbohydrates has therapeutic effects in some but not all irritable bowel syndrome (IBS) patients. We investigated genetic variation in human Carbohydrate-Active enZYmes (hCAZymes) genes in relation to the response to a FODMAP-lowering diet in the DOMINO study. HCAZy polymorphism was studied in IBS patients from the dietary (FODMAP-lowering; N=196) and medication (otilonium bromide; N=54) arms of the DOMINO trial via targeted sequencing of 6 genes of interest (AMY2B, LCT, MGAM, MGAM2, SI and TREH). hCAZyme defective (hypomorphic) variants were identified via computational annotation using clinical pathogenicity classifiers. Age- and sex-adjusted logistic regression was used to test hCAZyme polymorphisms in cumulative analyses where IBS patients were stratified into carrier and non-carrier groups (collapsing all hCAZyme hypomorphic variants into a single bin). Quantitative analysis of hCAZyme variation was also performed, in which the number of hCAZyme genes affected by a hypomorphic variant was taken into account. In the dietary arm, the number of hypomorphic hCAZyme genes positively correlated with treatment response rate (P=.03, OR=1.51 [CI=0.99-2.32]). In the IBS-D group (N=55), hCAZyme carriers were six times more likely to respond to the diet than non-carriers (P=.002, OR=6.33 [CI=1.83-24.77]). These trends were not observed in the medication arm. HCAZYme genetic variation may be relevant to the efficacy of a carbohydrate-lowering diet. This warrants additional testing and replication of findings, including mechanistic investigations of this phenomenon.

Safe and potent anti-CD19 CAR T-cells with shRNA-IL-6 gene silencing element in patients with refractory or relapsed B-cell acute lymphoblastic leukemia.

Severe cytokine release syndrome (sCRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) have limited the widespread use of chimeric antigen receptor T (CAR T)-cell therapy. We designed a novel anti-CD19 CAR (ssCART-19) with a small hairpin RNA (shRNA) element to silence the interleukin-6 (IL-6) gene, hypothesizing it could reduce sCRS and ICANS by alleviating monocyte activation and proinflammatory cytokine release. In a post hoc analysis of two clinical trials, we compared ssCART-19 with common CAR T-cells (cCART-19) in relapsed/refractory B-cell acute lymphoblastic leukemia (r/r B-ALL). Among 87 patients, 47 received ssCART-19 and 40 received cCART-19. Grade ≥3 CRS occurred in 14.89% (7/47) of the ssCART-19 group versus 37.5% (15/40) in the cCART-19 group (p = 0.036). ICANS occurred in 4.26% (2/47) of the ssCART-19 group (all grade 1) compared to 15% (2/40) of the cCART-19 group. Patients in the ssCART-19 group showed comparable rates of treatment response (calculated with rates of complete remission and incomplete hematological recovery) were 91.49% (43/47) for ssCART-19 and 85% (34/40) for cCART-19 (p = 0.999). With a median follow-up of 21.9 months, cumulative nonrelapse mortality was 10.4% for ssCART-19 and 13.6% for cCART-19 (p = 0.33). Median overall survival was 37.17 months for ssCART-19 and 32.93 months for cCART-19 (p = 0.40). Median progression-free survival was 24.17 months for ssCART-19 and 9.33 months for cCART-19 (p = 0.23). These data support the safety and efficacy of ssCART-19 for r/r B-ALL, suggesting its potential as a promising therapy.

Impact of baseline body mass index on antidepressant response: A study in newly diagnosed patients at a tertiary care center in Kolkata

Background: Depression, affecting 350 million globally, poses significant morbidity and mortality. The correlation between major depressive disorder (MDD) and obesity is noted, with studies indicating poorer treatment outcomes among obese individuals. Measuring weight and body mass index (BMI) could aid in predicting depression treatment outcomes, influencing drug efficacy due to their ease of measurement, amid the shared public health burden of MDD and obesity. Aims and Objectives: The aims and objectives of the study are to evaluate baseline BMI’s impact on antidepressant response in newly diagnosed outpatient department (OPD) patients at a tertiary care center. Materials and Methods: This longitudinal observational study was conducted with OPD patients at a tertiary care center, aged 18–65 years with newly diagnosed MDD. Assessment tools included the Diagnostic Criteria for Research accompanying the ICD-10, the Hamilton Rating Scale for Depression, and physical measurement devices. Sample size determination considered BMI groups: Normal to underweight (N1=120), overweight (N2=120), and obese (N3=70). The methodology involved patient history, examination, and follow-up assessments after 6 weeks, analyzing antidepressant response statistically. Results: Obese patients exhibited reduced treatment response rates compared to normal and overweight counterparts. Responders had lower mean BMI. Gender disparities in obesity prevalence were noted. Limitations: The study’s limitations include a small sample size of 310 cases, single-center design, and potential selection bias in a tertiary care setting. Conclusion: The findings underscore the complex relationship between BMI, depression severity, and treatment response. Obese individuals demonstrated higher initial depression scores and poorer treatment response, echoing previous research. The study highlights the need for personalized treatment approaches that consider individual BMI levels to optimize depression management strategies effectively.

Lenvatinib Plus Pembrolizumab versus Doxorubicin for Advanced or Recurrent Endometrial Cancer with Short Treatment-Free Intervals Following First-Line Carboplatin Plus Paclitaxel

Background: The treatment-free interval is a significant predictor of worse prognosis and poor response rates of the second-line treatment in patients with carboplatin and paclitaxel (PT)-pretreated, advanced, or recurrent endometrial cancer (EC). Whether lenvatinib plus pembrolizumab still confers a survival benefit compared with doxorubicin in patients with platinum-free intervals of &lt;6 months remains unclear. Methods: This multi-institutional retrospective analysis was performed using de-identified electronic health records from the TriNetX Research Network. Patients with advanced or recurrent ECs who received lenvatinib plus pembrolizumab or doxorubicin within six months of first-line PT were identified. A 1:1 propensity score matching (PSM) was conducted to control for potential confounding variables. Overall survival (OS) and adverse event profile were the primary and secondary outcomes. Results: Between January 2018 and February 2024, 130 patients with PT-treated, advanced, or recurrent ECs who received lenvatinib plus pembrolizumab and 122 patients who received doxorubicin at a platinum-free interval of &lt;6 months were identified across 31 healthcare organizations. In the balanced cohort following PSM with 117 patients in each group, treatment with lenvatinib plus pembrolizumab was associated with improved OS compared with treatment with doxorubicin (12.8 vs. 8.2 months, p = 0.012, hazard ratio: 0.65, 95% confidence interval: 0.46–0.91). Regarding adverse event analysis, a higher incidence of hypothyroidism and proteinuria was observed with lenvatinib plus pembrolizumab, and more hematological toxicities were observed with doxorubicin. Conclusions: in patients with treatment-free intervals of &lt;6 months, lenvatinib plus pembrolizumab still confers improved survival compared with doxorubicin in PT-treated, advanced, or recurrent ECs.

Fire needle therapy for the treatment of cancer pain: a protocol for the systematic review and meta-analysis.

Cancer patients frequently suffer pain as one of their symptoms. It includes acute and chronic pain and is one of the most feared symptoms for patients. About one-third of adults actively undergoing cancer treatment suffer from pain related to their condition. Cancer pain control remains suboptimal due to a lack of assessment, knowledge, and access. Fire needle therapy, a traditional Chinese medicine, offers a potentially beneficial addition to current pain management approaches. This protocol outlines a systematic review and meta-analysis to compile evidence and examine the pain-relieving effects and safety of fire needle therapy for cancer patients. We will systematically search China National Knowledge Infrastructure (CNKI), Wanfang Database, China Biology Medicine disc (CBM), China Science and Technology Journal Database (CSTJ or VIP), PubMed, Web of Science, Embase, Cochrane Central Registry of Controlled Trials (CENTRAL), Chinese Clinical Trial Registry (Chictr), Opengrey, Worldcat, and Scopus from inception through July 2023. Random control trials (RCTs) include all types of cancer patients (age ≥ 18 years) complaining of pain. The primary outcome will be changes in pain intensity measured by Visual Analogue Scale (VAS), Numerical Rating Scale (NRS), Neuropathic Pain Scale (NPS), or Brief Pain Inventory (BPI). Secondary outcomes include quality of life (EORTC QLQ-C30 and GCQ), performance status (KPS), times of burst pain, treatment response rate, the dose reduction of analgesic drugs, and side effects rates. Utilizing the Cochrane risk bias measurement tool: Risk of Bias 2 (RoB 2), the trials' quality will be evaluated, and meta-analysis will be performed using RevMan software (version 5.4). This systematic review will be the first comprehensive review of the literature to provide a meta-analysis of fire needle therapy for cancer pain, including only Random control trials (RCTs). For the sake of transparency and to avoid future duplication, the publication of this protocol offers a clear illustration of the procedures utilized in this evaluation. The results of our future studies may provide a new approach and theoretical basis for the treatment of cancer pain by medical oncology professionals. https://www.crd.york.ac.uk/prospero/, identifier CRD42023418609.

Clinical multi-dimensional prognostic nomogram for predicting the efficacy of immunotherapy in NSCLC

The advent of immunotherapy has greatly improved the prognosis of non-small cell lung (NSCLC) patients. However, given its low response rate and high cost of treatment, the search for valuable predictive markers of treatment efficacy is necessary. Considering the complexity and heterogeneity of the tumour and tumour microenvironment, the construction of a multi-dimensional prediction model is necessary. Therefore, we aimed to integrate clinical parameters, radiomic features, and immune signature data from NSCLC patients receiving immunotherapy to construct a multi-dimensional prediction model to better predict the efficacy of immunotherapy. The current study enrolled 137 NSCLC patients who received immunotherapy. We collected baseline clinical information, CT images, and tumour tissue specimens. Using 3D-Slicer software, radiomic features were extracted from patient CT images, and tumor tissue samples obtained before immunotherapy were subjected to immunohistochemical staining. Then, the least absolute shrinkage and selection operator (LASSO) Cox regression analysis was applied to downscale the data, and the radiomic features and immune signatures associated with the prognosis of immunotherapy patients were identified. The modified lung immune predictive index (mLIPI), radiomics score (Radioscore), immune score and multi-dimensional model nomogram were constructed. The C-index and area under the curve (AUC) were applied to evaluate the predictive efficacy of the models. Three radiomic features and three immune signatures that could predict the efficacy of immunotherapy were eventually screened. Multivariate analysis showed that the mLIPI, Radioscore, and immune score were independent predictive factors for PFS and OS (P < 0.05 for all models). The multi-dimensional model combining the three models showed better predictive efficacy than the mLIPI, Radioscore, and immune score (PFS: 0.721 vs. 0.662 vs. 0.610 vs. 0.610; OS: 0.727 vs. 0.661 vs. 0.601 vs. 0.602 respectively). The multi-dimensional model showed the best predictive efficacy, with C-index for PFS and OS higher than mLIPI, radioscore and immune score: 0.721 vs. 0.662 vs. 0.610 vs. 0.610 for PFS and 0.727 vs. 0.661 vs. 0.601 vs. 0.602 for OS, respectively. The AUC for the multi-dimensional model also performed better than those of the individual models: 0.771 vs. 0.684 vs. 0.715 vs. 0.711 for PFS and 0.768 vs. 0.662 vs. 0.661 vs. 0.658 for OS, respectively. The multi-dimensional model combining the three models had better predictive efficacy than any single model and was more likely to help provide patients personalized and precision medicine.

Whole-brain turbulent dynamics predict responsiveness to pharmacological treatment in major depressive disorder.

Depression is a multifactorial clinical syndrome with a low pharmacological treatment response rate. Therefore, identifying predictors of treatment response capable of providing the basis for future developments of individualized therapies is crucial. Here, we applied model-free and model-based measures of whole-brain turbulent dynamics in resting-state functional magnetic resonance imaging (fMRI) in healthy controls and unmedicated depressed patients. After eight weeks of treatment with selective serotonin reuptake inhibitors (SSRIs), patients were classified as responders and non-responders according to the Hamilton Depression Rating Scale 6 (HAMD6). Using the model-free approach, we found that compared to healthy controls and responder patients, non-responder patients presented disruption of the information transmission across spacetime scales. Furthermore, our results revealed that baseline turbulence level is positively correlated with beneficial pharmacological treatment outcomes. Importantly, our model-free approach enabled prediction of which patients would turn out to be non-responders. Finally, our model-based approach provides mechanistic evidence that non-responder patients are less sensitive to stimulation and, consequently, less prone to respond to treatment. Overall, we demonstrated that different levels of turbulent dynamics are suitable for predicting response to SSRIs treatment in depression.

Dietary Counseling Outcomes in Patients with Lung Cancer in an Upper-Middle-Income Country: An Open-Label Randomized Controlled Trial.

Background: Malnutrition harms treatment outcomes, QoL, and survival in lung cancer patients. Effective dietary counseling can improve nutrition, but few randomized controlled trials have focused on lung cancer patients. The objective of this study was to determine if dietary counseling improves nutritional and treatment outcomes when compared to routine care. Methods: This open-label parallel RCT was conducted at Maharaj Nakorn Chiang Mai Hospital in Thailand. The investigators used computer-generated blocked randomization to assign patients to dietary counseling by a nutritionist or routine care. The nutritionist sessions occurred before treatment, with follow-ups at 3-4 weeks and 12 weeks. The primary outcome was the mean percentage change in the body weight of patients at 12 weeks. Secondary outcomes included changes in the BMI, nutrition score, QoL, serum albumin level, lymphocyte count, energy and protein intake, treatment response, PFS, and OS. Results: Between April 2020 and May 2022, after completing recruitment, 80 lung cancer patients were randomized: 43 to dietary counseling and 37 to routine care. The dietary counseling group showed significant benefits, with smaller decreases in body weight at 3-4 weeks (-0.8% vs. -2.6%, p = 0.05) and 12 weeks (-1.1% vs. -4.3%, p = 0.05). They also had higher energy and protein intake levels and better treatment response rates. The secondary outcomes and significant adverse events did not differ significantly between the groups. Conclusions: Dietary counseling helps to maintain body weight, maintain dietary intake, and enhance treatment responses in lung cancer patients. Although not all nutritional markers or survival outcomes were affected, these findings highlight the importance of early nutritional interventions.

The Efficacy of Cabazitaxel in Treating Prostate Cancer: A Systematic Review and Meta-Analysis.

Cabazitaxel, a second-generation taxane chemotherapy agent, has demonstrated efficacy in treating metastatic castration-resistant prostate cancer (mCRPC) in patients who have previously received docetaxel-based therapy. By targeting microtubule dynamics, cabazitaxel inhibits cancer cell division and induces apoptosis, thereby extending survival and delaying disease progression in this challenging patient population. A systematic review and meta-analysis were done by searching the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE (including MEDLINE InProcess; OvidSP), Web of Science, Embase (OvidSP), and Scopus databases. ROB2 Cochrane tools assessment for RCTs. In the analysis, we used RevMan Cochrane software. Our research reveals significantly improved outcomes in terms of patient survival rates, both progression-free survival (PFS) and overall survival (OS), for cabazitaxel over comparative treatment (PFS HR 0.77 [0.61, 0.97]) (OS HR 0.79 [0.70, 0.88]). The treatment response rates were also favorable for cabazitaxel, reported as PSA Reduction Response of more than 50% (PRR) (odds ratio (OR) = 1.59 [0.56, 4.52]) and tumor response rate (TRR) (OR = 2.34 [1.28, 4.28]). Cabazitaxel was associated with significantly more incidence of adverse events. The risk ratio (RR) for serious adverse events was 1.64 [1.14, 2.35] for cabazitaxel compared to the current regimen. A systematic review and meta-analysis were done by searching in the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE (including MEDLINE InProcess; OvidSP), Web of Science, Embase (OvidSP), and Scopus databases. ROB2 Cochrane tools assessment for RCTs. In the analysis, we used RevMan Cochrane software.

Advancements in the use of nanopharmaceuticals for cancer treatment.

Advances in nanotechnology make it possible to specifically target therapies to cancer cells and neoplasms, guide the surgical resection of tumors, and optimize the effectiveness of radiological treatments. This research article provides a concise synthesis of current knowledge in the field of galenic pharmacy focused on targeted drug delivery in oncology. This research article synthesizes current knowledge in galenic pharmacy, focusing on targeted drug delivery in oncology and reviewing recent advancements in nanopharmaceuticals for cancer treatment. The data for this review are derived from a comprehensive analysis of the most cited scientific literature (Pubmed). Recent studies, clinical trials, and technological breakthroughs related to nanopharmaceuticals have been rigorously examined. This diverse source ensures a comprehensive representation of the latest developments in the field. The results highlight the emergence of nanopharmaceuticals as a promising approach to cancer treatment. The most common in oncology remain liposomes, nanopolymers, and nanocrystals. From a galenic point of view, these three forms offer a wide range of improvements compared to conventional forms such as improvement in solubility as well as stability. The same observation is in the clinic where treatment response rates are significantly improved. The most advantageous form will depend on the specific characteristics of each patient and each type of cancer. The precise design of nanocarriers allows for targeted drug delivery, enhancing therapeutic efficacy while reducing side effects. Concrete examples of clinical applications are presented, illustrating the practical potential of these advancements. In conclusion, this review provides a holistic overview of recent developments in galenic pharmacy for targeted drug delivery in oncology. The stability of nanocarriers is a crucial challenge because it conditions the effectiveness and safety of the drugs transported. Environmental and biological variations encountered in the body can compromise this stability, jeopardizing the therapeutic effectiveness and safety of treatments. Likewise, personalized approaches are essential to address interindividual variations in treatment response, as well as patients' pharmacogenomic profiles, in order to optimize therapeutic effectiveness and minimize adverse effects.

Baseline systemic inflammatory indices and clinicopathological features to predict the outcome of acute tubulointerstitial nephritis : Asingle-center retrospective study.

Acute tubulointerstitial nephritis (AIN) is an immune-mediated disorder that can cause acute kidney injury (AKI). We aimed to investigate the characteristics of patients with AIN and predictive factors for treatment response. In this study, thirty-one patients diagnosed with AIN on kidney biopsy between 2006 and 2021 were included. Baseline clinical, histopathological, and laboratory findings, including complete blood count (CBC), creatinine, erythrocyte sedimentation rate, C‑reactive protein, C3, C4, systemic immune inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and urinalysis were evaluated. Treatment response, mortality, and creatinine levels at the time of last follow-up were also noted. The median age was 46 years and 80.6% were female. Median baseline creatinine and proteinuria levels were 4.1 mg/dL and 0.84 gram/day. The median follow-up period was 14months and 93.5% received immunosuppressives. End-stage kidney disease (ESKD) developed in five patients (16.1%). Renal recovery (creatinine < 1.4 mg/dL) was observed in 17 patients (54.8%). Higher degrees of interstitial fibrosis, tubular atrophy, granuloma formation, global glomerulosclerosis, and higher baseline hemoglobin levels, in addition to alonger interval between first symptom to initiation of immunosuppressives were associated with renal nonrecovery, statistically. Also, patients who progressed to ESKD had higher baseline hemoglobin (p = 0.033) and lymphocyte (p = 0.044) and lower PLR levels (p = 0.016), as well as higher degrees of global glomerulosclerosis (p = 0.014), interstitial fibrosis (p = 0.042), and tubular atrophy (p = 0.030). Treatment response rates are low for AIN, which may lead to ESKD. Besides chronicity in histopathology specimens, higher baseline hemoglobin levels and lower platelet-to-lymphocyte ratio might be prognostic. Further studies should be conducted on new markers for AIN.
