RESUMEN

Cancer immunotherapy represents a revolutionary strategy, leveraging the patient's immune system to inhibit tumor growth and alleviate the immunosuppressive effects of the tumor microenvironment (TME). The recent emergence of immune checkpoint blockade (ICB) therapies, particularly following the first approval of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors like ipilimumab, has led to significant growth in cancer immunotherapy. The extensive explorations on diverse immune checkpoint antibodies have broadened the therapeutic scope for various malignancies. However, the clinical response to these antibody-based ICB therapies remains limited, with less than 15% responsiveness and notable adverse effects in some patients. This review introduces the emerging strategies to overcome current limitations of antibody-based ICB therapies, mainly focusing on the development of small interfering ribonucleic acid (siRNA)-based ICB therapies and innovative delivery systems. We firstly highlight the diverse target immune checkpoint genes for siRNA-based ICB therapies, incorporating silencing of multiple genes to boost anti-tumor immune responses. Subsequently, we discuss improvements in siRNA delivery systems, enhanced by various nanocarriers, aimed at overcoming siRNA's clinical challenges such as vulnerability to enzymatic degradation, inadequate pharmacokinetics, and possible unintended target interactions. Additionally, the review presents various combination therapies that integrate chemotherapy, phototherapy, stimulatory checkpoints, ICB antibodies, and cancer vaccines. The important point is that when used in combination with siRNA-based ICB therapy, the synergistic effect of traditional therapies is strengthened, improving host immune surveillance and therapeutic outcomes. Conclusively, we discuss the insights into innovative and effective cancer immunotherapeutic strategies based on RNA interference (RNAi) technology utilizing siRNA and nanocarriers as a novel approach in ICB cancer immunotherapy.

RESUMEN

ALK-positive NSCLC patients demonstrate initial responses to ALK tyrosine kinase inhibitor (TKI) treatments, but eventually develop resistance, causing rapid tumor relapse and poor survival rates. Growing evidence suggests that the combination of drug and immune therapies greatly improves patient survival; however, due to the low immunogenicity of the tumors, ALK-positive patients do not respond to currently available immunotherapies. Tumor-associated macrophages (TAMs) play a crucial role in facilitating lung cancer growth by suppressing tumoricidal immune activation and absorbing chemotherapeutics. However, they can also be programmed toward a pro-inflammatory tumor suppressive phenotype, which represents a highly active area of therapy development. Iron loading of TAMs can achieve such reprogramming correlating with an improved prognosis in lung cancer patients. We previously showed that superparamagnetic iron oxide nanoparticles containing core-cross-linked polymer micelles (SPION-CCPMs) target macrophages and stimulate pro-inflammatory activation. Here, we show that SPION-CCPMs stimulate TAMs to secrete reactive nitrogen species and cytokines that exert tumoricidal activity. We further show that SPION-CCPMs reshape the immunosuppressive Eml4-Alk lung tumor microenvironment (TME) toward a cytotoxic profile hallmarked by the recruitment of CD8+ T cells, suggesting a multifactorial benefit of SPION-CCPM application. When intratracheally instilled into lung cancer-bearing mice, SPION-CCPMs delay tumor growth and, after first line therapy with a TKI, halt the regrowth of relapsing tumors. These findings identify SPIONs-CCPMs as an adjuvant therapy, which remodels the TME, resulting in a delay in the appearance of resistant tumors.

RESUMEN

Tumor microenvironment (TME)-responsive size-changeable and biodegradable nanoplatforms for multimodal therapy possess huge advantages in anti-tumor therapy. Hence, we developed a hyaluronic acid (HA) modified CuS/MnO2 nanosheets (HCMNs) as a multifunctional nanoplatform for synergistic chemodynamic therapy (CDT)/photothermal therapy (PTT)/photodynamic therapy (PDT). The prepared HCMNs exhibited significant NIR light absorption and photothermal conversion efficiency because of the densely deposited ultra-small sized CuS nanoparticles on the surface of MnO2 nanosheet. They could precisely target the tumor cells and rapidly decomposed into small sized nanostructures in the TME, and then efficiently promote intracellular ROS generation through a series of cascade reactions. Moreover, the local temperature elevation induced by photothermal effect also promote the PDT based on CuS nanoparticles and the Fenton-like reaction of Mn2+, thereby enhancing the therapeutic efficiency. Furthermore, the T1-weighted magnetic resonance (MR) imaging was significantly enhanced by the abundant Mn2+ ions from the decomposition process of HCMNs. In addition, the CDT/PTT/PDT synergistic therapy using a single NIR light source exhibited considerable anti-tumor effect via in vitro cell test. Therefore, the developed HCMNs will provide great potential for MR imaging and multimodal synergistic cancer therapy.

RESUMEN

The reported benefits of nature contact on human health and well-being have prompted the rise of nature prescriptions with health professionals recommending nature exposure. Due to the success of nature prescriptions and calls for greater reciprocity between people and the planet, this essay proposes to leverage health behavior promotion strategies to integrate planetary health prescriptions (Earth RX) into existing nature prescription frameworks with a vision to counsel patients on both the health and well-being benefits of nature contact as well as earth-sustaining behaviors, all of which fosters a compassionate interdependence between personal and planetary well-being. The essay emphasizes the importance of co-designed stakeholder collaboration for program success, addressing factors such as trust, perceived benefits, and accessibility. Finally, this essay concludes that integrating Earth RX in nature prescription programs strategically aligns with the principles of integrative health, acknowledging the reciprocal relationship between human health and well-being and planetary well-being.

RESUMEN

Background: Several factors can affect overall survival of head and neck cancer (HNC) patients, including characteristics of the cancer disease and response to treatments. However, patients' nutritional status and the effectiveness of medical nutrition therapy (MNT) can also impact overall survival. The primary goal of our research was to collect real-life data on the use of MNT in HNC patients and to specifically investigate the correlation between survival and the duration of uninterrupted (persistent) nutrition. Method: The data of this retrospective, analytical, cohort study was collected from electronic healthcare records from the Hungarian National Health Insurance Fund Management. Overall, 38,675 HNC patients' data of the period between 2012 and 2021 was used. We applied multi-step exclusions to identify patient groups accurately and to avoid biasing factors. Statistical analysis was done by the Kaplan-Meier method, log-rank test, and Cox regression analysis. Results: Throughout the investigated period 16,871 (64%) patients received MNT therapy out of 26,253 newly diagnosed patients (≥18 years). In terms of the persistence of MNT, we divided the patients into three groups (1-3; 4-6; ≥7-month duration of MNT). When comparing these groups, we found that patients receiving long-term (≥7 months) MNT had a significantly longer overall survival (p < 0.0001) than those who received MNT for a shorter duration, both in locally advanced and recurrent/metastatic cases. Conclusion: The main outcome of the study is that there is a positive correlation between the persistence of MNT and the overall survival in HNC patients when nutritional intervention lasts several months. It highlights the responsibility of the specialists during the patient journey to use MNT early and to continue its use for as long as it is beneficial to the patients.

RESUMEN

The high prevalence and severity of hepatocellular carcinoma (HCC) present a significant menace to human health. Despite the significant advancements in nanotechnology-driven antineoplastic agents, there remains a conspicuous gap in the development of targeted chemotherapeutic agents specifically designed for HCC. Consequently, there is an urgent need to explore potent drug delivery systems for effective HCC treatment. Here we have exploited the interplay between HCC and adipocyte to engineer a hybrid adipocyte-derived exosome platform, serving as a versatile vehicle to specifically target HCC and exsert potent antitumor effect. A lipid-like prodrug of docetaxel (DSTG) with a reactive oxygen species (ROS)-cleavable linker, and a lipid-conjugated photosensitizer (PPLA), spontaneously co-assemble into nanoparticles, functioning as the lipid cores of the hybrid exosomes (HEMPs and NEMPs). These nanoparticles are further encapsuled within adipocyte-derived exosome membranes, enhancing their affinity towards HCC cancer cells. As such, cancer cell uptakes of hybrid exosomes are increased up to 5.73-fold compared to lipid core nanoparticles. Our in vitro and in vivo experiments have demonstrated that HEMPs not only enhance the bioactivity of the prodrug and extend its circulation in the bloodstream but also effectively inhibit tumor growth by selectively targeting hepatocellular carcinoma tumor cells. Self-facilitated synergistic drug release subsequently promoting antitumor efficacy, inducing significant inhibition of tumor growth with minimal side effects. Our findings herald a promising direction for the development of targeted HCC therapeutics.

RESUMEN

The field of cancer therapy is witnessing the emergence of immunotherapy, an innovative approach that activates the body own immune system to combat cancer. Immunogenic cell death (ICD) has emerged as a prominent research focus in the field of cancer immunotherapy, attracting significant attention in recent years. The activation of ICD can induce the release of damage-associated molecular patterns (DAMPs), such as calreticulin (CRT), adenosine triphosphate (ATP), high mobility group box protein 1 (HMGB1), and heat shock proteins (HSP). Subsequently, this process promotes the maturation of innate immune cells, including dendritic cells (DCs), thereby triggering a T cell-mediated anti-tumor immune response. The activation of the ICD ultimately leads to the development of long-lasting immune responses against tumors. Studies have demonstrated that partial therapeutic approaches, such as chemotherapy with doxorubicin, specific forms of radiotherapy, and phototherapy, can induce the generation of ICD. The main focus of this article is to discuss and review the therapeutic methods triggered by nanoparticles for ICD, while briefly outlining their anti-tumor mechanism. The objective is to provide a comprehensive reference for the widespread application of ICD.

RESUMEN

BACKGROUND: Despite the potential radiotoxicity in differentiated thyroid cancer (DTC) patients with high-dose 131I therapy, the alterations and regulatory mechanisms dependent on intestinal microecology remain poorly understood. We aimed to identify the characteristics of the gut microbiota and metabolites in DTC patients suffering from high-dose 131I therapy and explore the radioprotective mechanisms underlying arachidonic acid (ARA) treatment. METHODS: A total of 102 patients with DTC were recruited, with fecal samples collected before and after 131I therapy for microbiome and untargeted and targeted metabolomic analyses. Mice were exposed to total body irradiation with ARA replenishment and antibiotic pretreatment and were subjected to metagenomic, metabolomic, and proteomic analyses. RESULTS: 131I therapy significantly changed the structure of gut microbiota and metabolite composition in patients with DTC. Lachnospiraceae were the most dominant bacteria after 131I treatment, and metabolites with decreased levels and pathways related to ARA and linoleic acid were observed. In an irradiation mouse model, ARA supplementation not only improved quality of life and recovered hematopoietic and gastrointestinal systems but also ameliorated oxidative stress and inflammation and preserved enteric microecology composition. Additionally, antibiotic intervention eliminated the radioprotective effects of ARA. Proteomic analysis and ursolic acid pretreatment showed that ARA therapy greatly influenced intestinal lipid metabolism in mice subjected to irradiation by upregulating the expression of hydroxy-3-methylglutaryl-coenzyme A synthase 1. CONCLUSION: These findings highlight that ARA, as a key metabolite, substantially contributes to radioprotection. Our study provides novel insights into the pivotal role that the microbiota-metabolite axis plays in radionuclide protection and offers effective biological targets for treating radiation-induced adverse effects.

RESUMEN

OBJECTIVE: To report the protocol of a study evaluating the efficacy of transdermal oestradiol (E2) gel in reducing the adverse effects of androgen deprivation therapy (ADT), specifically on sexual function, and to assess the utility of E2 in combination with supervised exercise. STUDY DESIGN AND METHODS: The primary endpoint of this open-label Phase IIA randomized controlled trial is the efficacy of transdermal E2 gel. Secondary endpoints include: (i) the occurrence of ADT-induced adverse effects; (ii) the safety and tolerability of E2; (iii) the impact of E2 with or without exercise on physical, physiological, muscle, and systemic biomarkers; and (iv) quality of life. The trial will recruit high-risk PCa patients (n = 310) undergoing external beam radiation therapy with adjuvant subcutaneous ADT. Participants will be stratified and randomized in a 1:1 ratio to either the E2 + ADT arm or the ADT-only control arm. Additionally, a subset of patients (n = 120) will be randomized into a supervised exercise programme. RESULTS: The primary outcome is assessed according to the efficacy of E2 in mitigating the deterioration of Expanded Prostate Cancer Index Composite sexual function domain scores. Secondary outcomes are assessed according to the occurrence of ADT-induced adverse effects, safety and tolerability of E2, impact of E2 with or without exercise on physical performance, body composition, bone mineral density, muscle size, systematic biomarkers, and quality of life. CONCLUSION: The ESTRACISE study's innovative design can offer novel insights about the benefits of E2 gel, and the substudy can reinforce the benefits resistance training and deliver valuable new novel insights into the synergistic benefits of E2 gel and exercise, which are currently unknown. TRIAL REGISTRATION: The protocol has been registered in euclinicaltrials.eu (2023-504704-28-00) and in clinicaltrials.gov (NCT06271551).

RESUMEN

The construction and optimization of a single phototherapeutic agent with photoluminescence, type I photodynamic therapy (PDT), and photothermal therapy (PTT) functions remain challenging. In this study, we aimed to design and synthesize four donor-acceptor (D-A) type aggregation-induced emission molecules: PSI, TPSI, PSSI, and TPSSI. We employed phenothiazine as an electron donor and 1,3-bis(dicyanomethylidene)indan as a strong electron acceptor in the synthesis process. Among them, TPSSI exhibited efficient type I reactive oxygen species generation, high photothermal conversion efficiency (45.44 %), and near-infrared emission. These observations can be attributed to the introduction of a triphenylamine electron donor group and a thiophene unit, which resulted in increased D-A strengths, a reduced singlet-triplet energy gap, and increased free intramolecular motion. TPSSI was loaded into bovine serum albumin to prepare biocompatible TPSSI nanoparticles (NPs). Our results have indicated that TPSSI NPs can target lipid droplets with negligible dark toxicity and can efficiently generate O2•- in hypoxic tumor environments. Moreover, TPSSI NPs selectively targeted 4T1 tumor tissues and exhibited a good PDT-PTT synergistic effect in vitro and in vivo. We believe that the successful preparation of multifunctional phototherapeutic agents will promote the development of efficient tumor diagnosis and treatment technologies. STATEMENT OF SIGNIFICANCE: The construction of a single phototherapeutic agent with photoluminescence, type I photodynamic therapy, and photothermal therapy functions, and its optimization remain challenging. In this study, we construct four donor-acceptor aggregation-induced emission molecules using phenothiazine as an electron donor and 1,3-Bis(dicyanomethylidene)indan as a strong electron acceptor. By optimizing the molecular structure, an integrated phototherapy agent with fluorescence imaging ability and high photodynamic / photothermal therapy performance was prepared. We believe that the successful preparation of multifunctional phototherapeutic agents will promote the development of efficient tumor diagnosis and treatment technology.

RESUMEN

PURPOSE: To determine whether visible light is needed to elicit axial eye shortening by exposure to long wavelength light. METHODS: Incoherent narrow-band red (620 ± 10 nm) or near-infrared (NIR, 875 ± 30 nm) light was generated by an array of light-emitting diodes (LEDs) and projected monocularly in 17 myopic and 13 non-myopic subjects for 10 min. The fellow eye was occluded. Light sources were positioned 50 cm from the eye in a dark room. Axial length (AL) was measured before and after the exposure using low-coherence interferometry. RESULTS: Non-myopic subjects responded to red light with significant eye shortening, while NIR light induced minor axial elongation (-13.3 ± 17.3 µm vs. +6.5 ± 11.6 µm, respectively, p = 0.005). Only 41% of the myopic subjects responded to red light exposure with a decrease in AL and changes were therefore, on average, not significantly different from those observed with NIR light (+0.2 ± 12.1 µm vs. +1.1 ± 11.2 µm, respectively, p = 0.83). Interestingly, there was a significant correlation between refractive error and induced changes in AL after exposure to NIR light in myopic eyes (r(15) = -0.52, p = 0.03) and induced changes in AL after exposure to red light in non-myopic eyes (r(11) = 0.62, p = 0.02), with more induced axial elongation with increasing refractive error. CONCLUSIONS: Incoherent narrow-band red light at 620 nm induced axial shortening in 77% of non-myopic and 41% of myopic eyes. NIR light did not induce any significant changes in AL in either refractive group, suggesting that the beneficial effect of red laser light therapy on myopia progression requires visible stimulation and not simply thermal energy.

RESUMEN

Many patients who receive treatment for opioid use disorder (OUD) report experiencing chronic pain (CP), which is associated with high levels of ongoing nonmedical opioid use and low retention in OUD treatment. In pilot studies of patients with OUD receiving buprenorphine or methadone who had CP, cognitive behavioral therapy (CBT) attenuated nonmedical opioid use compared with treatment-as-usual (TAU), but patients in both treatment arms exhibited similar pain improvements. Adding exercise and stress reduction to this model may augment pain-related outcomes. With funding from National Institutes of Health, we plan to conduct a randomized clinical trial of 316 patients with OUD and CP to test the effectiveness of TAU compared with Stepped Care for Patients to Optimize Whole Recovery (SC-POWR) to reduce nonmedical opioid use and pain (primary outcomes) (Aim 1) and decrease pain intensity and interference, alcohol use, anxiety, depression and stress, and improve sleep (secondary outcomes) (Aim 2). Eligible participants will be randomized to receive TAU (buprenorphine or methadone and at least once a month individual or group counseling) or SC-POWR (ie, TAU and up to 12 CBT sessions) for 24 weeks. Based on prespecified nonresponse criteria, SC-POWR may be stepped up at week 6 to receive onsite weekly group sessions of exercise (Wii Fit, Tai Chi) and "stepped up" again at week 15 to receive weekly group sessions of stress reduction (relaxation training, auricular acupuncture). They will be followed for another 24 weeks to evaluate durability of treatment response for illicit opioid use, alcohol use, pain, anxiety, depression, stress, sleep, and retention in medications for OUD (Aim 3).

RESUMEN

OBJECTIVE: Vulvodynia is a chronic clinical condition characterized by provoked or non-provoked vulvar pain for at least 3 months of unknown etiology. The onset of vulvodynia involves a complex interplay of peripheral and central pain mechanisms, such as pelvic floor muscle and autonomic dysfunction, and interpersonal factors. A stepwise approach of pelvic floor physical therapy as medical management is suggested. In this scenario, by this meta-analysis of randomized controlled trials, we aimed to evaluate the efficacy of rehabilitation interventions in patients with vulvodynia. METHODS: On October 13, 2022, PubMed, Scopus, and Web of Science were systematically searched for randomized controlled trials that assessed the efficacy of the rehabilitative approach to pain during intercourse in patients with vulvodynia. The quality assessment was performed with the Cochrane risk-of-bias tool for randomized trials. The trial registration number is CRD42021257449. At the end of the search, 9 studies were included for a total of 332 patients. A pairwise meta-analysis was performed to highlight the efficacy of rehabilitative approaches for reducing pain during intercourse, as measured with a visual analog scale or a numerical rating scale. RESULTS: Meta-analysis showed that all these rehabilitative approaches had an overall effect size of -1.43 (95% CI = -2.69 to -0.17) in decreasing vulvodynia pain in terms of the visual analog scale. In the subgroup analysis, a significant effect size in acupuncture (effect size = -2.36; 95% CI = -3.83 to -0.89) and extracorporeal shockwave therapy (effect size = -2.94; 95% CI = -4.31 to -1.57; I2 = 58%) was observed. According to the Cochrane risk-of-bias tool, a low risk of bias for outcome selection in 89% of studies. CONCLUSION: Findings from this meta-analysis suggested that the physical agent modalities and complementary medicine techniques in people with vulvodynia appear to be more effective than placebo, sham, or waiting list. Further evidence on physical agent modalities and complementary therapies are warranted in the future. IMPACT: This was the first systematic review and meta-analysis of randomized controlled trials to provide evidence on the efficacy of rehabilitation interventions in patients with vulvodynia.

RESUMEN

Background: Ankyloglossia (AG) diagnoses are increasingly common, and management is not standardized. Nonsurgical alternative therapies are frequently recommended in conjunction with or instead of frenotomy, with uncertain evidence. Objective: To evaluate the efficacy of nonsurgical alternative therapies (chiropractic care, myofunctional therapy, and osteopathy) in improving breastfeeding for infants diagnosed with AG. Methods: PubMed, Embase, CINAHL, Scopus, Web of Science, Clinicaltrials.gov, and Google Scholar were searched (September-October 2023). Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A librarian-designed search included the terms "Ankyloglossia," "Non-surgical," "myofunctional therapy," "chiropractic," "osteopathy," and related therapies, with no date restrictions. English language studies of infants <24 months with AG and alternative therapy were included. Risk-of-bias evaluation used Newcastle-Ottawa Scale (NOS). Results: Of 1,304 identified articles, four studies (2016-2022) met inclusion criteria (two cross-sectional, one case report, and one case series). All studies reported frenotomy in combination with alternative therapy yielded favorable outcomes for maternal pain, weight gain, feeding duration, and maintenance of latch. The risk of bias was moderate for two studies, low for the case series, and not calculated for the case report, which has an inherent high risk of bias. All studies lacked control or comparator groups preventing definitive conclusions about the role of alternative therapies in AG. Conclusion: Although some studies suggest the potential benefits of combining alternative therapies with surgery for AG-related breastfeeding issues, the lack of control groups renders the evidence inconclusive. Nonsurgical approaches alone currently lack sufficient evidence. As these alternative therapies gain popularity, rigorous research is crucial to determine their cost-effectiveness and role in managing AG.

RESUMEN

INTRODUCTION: Transient hypercalcaemia due to teriparatide occurs in up to 11% of patients though delayed hypercalcaemia (> 24 h post injection) is rare. We report the case of a female who developed significant delayed hypercalcaemia after teriparatide treatment for osteoporosis and review other cases in the literature to date. CASE REPORT: A 72-year-old female on teriparatide for the treatment of osteoporosis was found to have hypercalcaemia (3.30 mmol/l) on routine testing approximately 3 months after starting therapy. Serum calcium pretreatment was normal at 2.39 mmol/l. She was admitted to the hospital for investigations which identified a serum 25-hydroxyvitamin D of 94 nmol/l, a low parathyroid hormone of 6.0 pg/ml, and normal test results for 1,25 dihydroxyvitamin D (115 pmol/l), parathyroid hormone-related peptide (< 1.4 pmol/ml), serum electrophoresis and angiotensin-converting enzyme (39 IU/l). CT abdomen, pelvis, and thorax revealed no evidence of malignancy and an isotope bone scan ruled out skeletal metastases. Serum calcium normalised (2.34 mmol/l) several days after stopping teriparatide and calcium supplements and administering intravenous fluid. On restarting teriparatide, delayed hypercalcaemia reoccurred and treatment was switched to denosumab. DISCUSSION: Delayed moderate to severe hypercalcaemia (serum calcium > 3.0 mmol/l) due to teriparatide is rare but may lead to therapy withdrawal. The underlying predisposing risk factors remain unclear and highlight the importance of a routine serum calcium assessment on therapy.

RESUMEN

Understanding and processing life experiences are essential in the treatment of personality disorders to promote personal recovery and psychological wellbeing. In this qualitative case report, drafted in co-creation between the client, clinical psychologist, and art therapist, individual treatment consisted of two psychotherapeutic interventions, "An Empowering Story" and life-story-focused art therapy, in 12 parallel sessions for 24 weeks. Hilda, 68 years of age, had been diagnosed with an unspecified personality disorder and various traits of borderline personality disorder. She experienced emotional exhaustion following long-term mental health problems rooted in a traumatic early childhood. This affected her ability to manage her emotions and social relations, resulting in the sense that her life had no meaning. Hilda was invited to reconstruct her life experiences, divided into the past, turning point, and present/future, in a written and a painted life story. This allowed for the integration of traumatic as well as positive memories, enhanced self-compassion, and meaning making. She developed self-reflection and integration of internal conflicts leading to a better emotional balance and self-understanding. Art therapy emphasizes bottom-up regulatory processes, while narrative psychology supports top-down regulatory processes. The combined approach effectively integrated bottom-up, experiential, sensory experiences with top-down, cognitive emotion-regulation processes. The results suggest that psychotherapeutic interventions involving a multi-pronged, complementary, and thus more holistic approach can support personal recovery in personality disorders.

RESUMEN

CONTEXT: Pre-diabetes is a significant public health problem worldwide. India has a very high rate of progression from pre-diabetes to diabetes, 75-78 per thousand persons per year. OBJECTIVE: To study the efficacy of individualized homeopathic medicinal products (HMPs) against placebos in preventing the progression from pre-diabetes to diabetes. DESIGN: Six-month, double-blind, randomized (1:1), two parallel arms, placebo-controlled trial. SETTING: Outpatient departments of D. N. De Homoeopathic Medical College and Hospital, Kolkata, West Bengal, India. PATIENTS: Sixty participants with pre-diabetes. INTERVENTIONS: Verum: HMPs plus yoga therapy (YT; n = 30); control: identical-looking placebos plus YT (n = 30). MAIN OUTCOME MEASURES: The primary efficacy endpoint was the proportion of participants progressing from pre-diabetes to diabetes, measured after three and six months. Secondary outcomes comprised of fasting blood glucose (FBS), oral glucose tolerance test (OGTT), glycated hemoglobin percentage (HbA1c%), lipid profile, liver enzymes (alanine transaminase, aspartate transaminase), urea and creatinine, and Measure Yourself Medical Outcome Profile version 2 (MYMOP-2); all measured after 3 and 6 months. RESULTS: The proportion of participants converted from pre-diabetics to diabetics (n/N; n = diabetics, N = prediabetics) was significantly less in the verum group than control: HbA1C% (month 3: verum - 2/30 versus control - 11/30, p = 0.003; month 6: 3/30 vs. 2/30, p = 0.008), OGTT (month 3: 0/30 vs. 8/30, p = 0.015; month 6: 0/30 vs. 1/30, p = 0.008), but not according to FBS (month 3: 1/30 vs. 1/30, p = 0.779; month 6: 1/30 vs. 3/30, p = 0.469). Several secondary outcomes also revealed significant improvements in the verum group than in placebo: HbA1C% (p < 0.001), OGTT (p = 0.001), serum ALT (p = 0.031), creatinine (p = 0.012), and MYMOP-2 profile scores (p < 0.001). Sulphur, Bryonia alba, and Thuja occidentalis were the most frequently indicated medicines. Thus, HMPs outperformed placebos by successfully preventing the progression of pre-diabetes to diabetes. TRIAL REGISTRATION: Clinical Trials Registry - India CTRI/2022/04/042,026; UTN: U1111-1277-0021.

RESUMEN

OBJECTIVE: To investigate the effect of cervical mobilization on joint position sense, balance and gait in multiple sclerosis (MS) patients. METHODS: Sixteen MS patients received traditional rehabilitation and traditional rehabilitation+cervical mobilization treatments in different orders, 2 days a week for 4 weeks. For the cervical mobilization, joint traction and shifts with myofascial release techniques were applied. Joint position sense was evaluated from the bilateral knee and ankle joints with a digital goniometer, balanced with the Berg Balance Test (BBT), the Functional Reach Test, and gait with the Dynamic Gait Index (DGI) and the Timed 25-Foot Walk Test. RESULTS: Improvements were determined in joint position sense, balance, gait with both treatment methods (p < 0.05). With the addition of cervical mobilization to traditional treatment, there was observed to be an increased effect carried over in knee joint position sense and BBT (p < 0.05). The BBT and DGI scores improved in the group applied with cervical mobilization following the washout period (p < 0.05). CONCLUSIONS: Cervical mobilization could be effective in improving joint position sense, balance and gait, and accelerated improvements in a short time. The application of cervical mobilization could be a supportive treatment method to improve position sense, balance and gait in patients with MS.

RESUMEN

Metastatic melanoma is an aggressive skin cancer with high mortality and recurrence rates. Despite the clinical success of recent immunotherapy approaches, prevailing resistance rates necessitate the continued development of novel therapeutic options. Photoimmunotherapy (PIT) is emerging as a promising immunotherapy strategy that uses photodynamic therapy (PDT) to unleash systemic immune responses against tumor sites while maintaining the superior tumor-specificity and minimally invasive nature of traditional PDT. In this review, we discuss recent advances in PIT and strategies for the management of melanoma using PIT. PIT can strongly induce immunogenic cell death, inviting the concomitant application of immune checkpoint blockade or adoptive cell therapies. PIT can also be leveraged to selectively remove the suppressive immune populations associated with immunotherapy resistance. The modular nature of PIT therapy design combined with the potential for patient-specific antigen selection or drug co-delivery makes PIT an alluring option for future personalized melanoma care.

RESUMEN

A planar conjugated ligand functionalized with bithiophene and its Ru(II), Os(II), and Ir(III) complexes have been constructed as single-molecule platform for synergistic photodynamic, photothermal, and chemotherapy. The complexes have significant two-photon absorption at 808 nm and remarkable singlet oxygen and superoxide anion production in aqueous solution and cells when exposed to 808 nm infrared irradiation. The most potent Ru(II) complex Ru7 enters tumor cells via the rare macropinocytosis, locates in both nuclei and mitochondria, and regulates DNA-related chemotherapeutic mechanisms intranuclearly including DNA topoisomerase and RNA polymerase inhibition and their synergistic effects with photoactivated apoptosis, ferroptosis and DNA cleavage. Ru7 exhibits high efficacy in vivo for malignant melanoma and cisplatin-resistant non-small cell lung cancer tumors, with a 100 % survival rate of mice, low toxicity to normal cells and low residual rate. Such an infrared two-photon activatable metal complex may contribute to a new generation of single-molecule-based integrated diagnosis and treatment platform to address drug resistance in clinical practice and phototherapy for large, deeply located solid tumors.
