Ozonoterapia y cáncer: mito o realidad / Ozone Therapy and Cancer: Myth or Reality

Introducción: El uso clínico de la ozonoterapia se incrementa cada día. Abarca disímiles especialidades médicas como la oncología. En Cuba las investigaciones que evalúan el empleo de la ozonoterapia en pacientes con cáncer son escasas, se precisan estudios científicos que demuestren su eficacia clínica. Objetivo: Explicar los mecanismos farmacológicos y bioquímicos de la ozonoterapia y su uso en el cáncer como terapia complementaria. Métodos: Se consultaron bases de datos disponibles a través de la red de Infomed. Se utilizaron como palabras clave: cáncer, ozonoterapia y estrés oxidativo. Se seleccionaron artículos originales y de revisión sistemáticos de los últimos diez años que evaluaron la utilización de la ozonoterapia en el tratamiento del cáncer. Resultados: El cáncer es per se una enfermedad inductora de estrés oxidativo. La ozonoterapia respalda su utilización como una terapia adyuvante mediante el preacondicionamiento oxidativo que estimula los sistemas antioxidantes de la célula contra la acción de los radicales libres. Así, se logra neutralizar la acción nociva del estrés oxidativo. El ozono incrementa la eficacia de la radio - quimioterapia y ayuda a reducir los efectos secundarios de estos tratamientos al activar los sistemas antioxidantes de la célula. La ozonoterapia se caracteriza por la simplicidad de su aplicación, bajos costos, alta efectividad y prácticamente ausencia de efectos colaterales en comparación con otros tratamientos adyuvantes. Conclusiones: El uso de la ozonoterapia en oncología como una terapia adyuvante representó un recurso terapéutico de gran valor dado por su perfil de efectividad y seguridad. Su uso podría extenderse para disminuir los efectos secundarios y mejorar la calidad de vida de los pacientes(AU)

Introduction: The clinical use of ozone therapy is increasing every day worldwide and it covers different medical specialties, including oncology. However, in Cuba, the investigations that evaluate the use of ozone therapy in cancer patients are scarce, so scientific studies are needed to demonstrate its clinical efficacy. Objective: To explain the pharmacological and biochemical mechanisms of ozone therapy and its use in cancer as a complementary therapy. Methods: Databases available through Infomed Network were consulted. Key words used were cancer, ozone therapy and oxidative stress. Original and systematic review articles from the last ten years that evaluated the use of ozone therapy in the treatment of cancer were selected. Results: Cancer is, as such, a disease that induces oxidative stress. Ozone therapy supports its use as an adjuvant therapy through oxidative pre-conditioning that stimulates the cell's antioxidant systems against the action of free radicals. Thus, it is possible to neutralize the harmful action of oxidative stress. Ozone increases the efficacy of radio-chemotherapy and helps reducing the side effects of these treatments by activating the cell's antioxidant systems. Ozone therapy is characterized by the simplicity of its application, low costs, high effectiveness and with practically no side effects, compared to other adjuvant treatments. Conclusions: The use of ozone therapy in oncology as an adjuvant therapy represented a therapeutic resource of great value given its effectiveness and safety profile. Its use could be extended to improve tissue oxygenation and thus enhance the efficacy of radiochemotherapy, reducing side effects and improving the patients's quality of life(AU)

Validation of a computerized decision support system to review pharmacotherapy treatment: scheduling guidelines.

BACKGROUND: The review of pharmacotherapy can be conceptualized as a service in which the drugs used by the patient are reviewed to control the risks as well as to improve the results of the drug therapy, detecting, solving, and preventing issues associated with the drug, readjusting the doses and times (schedule) so that the treatment is not incompatible or in duplicity. METHODS: The aim of the study was to validate an intelligent information system, which was developed to assist the scheduling activity in the pharmacotherapy review. The system used the concept of Genetic Algorithms. To validate the system, hypothetical cases were elaborated considering various aspects of pharmacotherapy such as underdose, overdose, drug interactions and contraindications. These cases were tested in the system and were also analyzed by pharmaceutical experts with clinical and research experience in the pharmacotherapy review process. The degree of agreement between the assessments of the appointments carried out by the pharmaceutical specialists and by the system were measured using the Kappa index with a 95% confidence interval. RESULTS: In detecting errors and make propositions, the system was able to identify 80% of errors, with pharmaceutical experts identifying between 20 and 70% of errors. In relation the results of kappa between the cases, the system had 87,3% of concordance, whereas the best pharmaceutical expert had 75,5% of concordance, considering the correct answer. CONCLUSION: It can be concluded that with the methodology used, the investigation met the objectives and confirmed the system is effective for pharmaceutical review process. There are indications that the system can help in the Pharmacotherapy review process, being able to find prescription errors as well as to establish times for the use of medications according to the patient's routine.

Pharmaceutical Care in Primary Care: an Experience with Hypertensive Patients in the North of Brazil

Abstract Background: Uncontrolled blood pressure has been associated with poor adherence to drug treatment. Objectives: To assess blood pressure control in hypertensive patients attending primary health centers after implementation of a pharmaceutical follow-up program in a city of the north of Brazil. Methods: Observational, cross sectional, descriptive study with 163 hypertensive patients attending public primary health care centers - one located on the riverside and one in the urban area of the city of Santarem, western Pará, Brazil. Adherence to the anti-hypertensive treatment was assessed using the eight-item Morisky test. Pharmacotherapy follow-up (Dader method) of patients with uncontrolled hypertension and non-adherent to anti-hypertensive treatment was performed. Results of the normality test showed that the data did not follow a normal distribution. Continuous variables were then compared using the Wilcoxon signed-rank test, and categorical variables by the likelihood ratio and the McNemar tests. Statistical significance was set at 5%. Results: Of the total sample, 94.5% were not adherent to anti-hypertensive drug therapy and 77.2% had uncontrolled hypertension. Adherence rate was higher in men than women (p=0.006). Pharmacotherapy follow-up improved blood pressure levels, particularly systolic blood pressure (p<0.001). Conclusion: An individualized pharmacotherapeutic follow-up, considering regional and cultural specificities, can contribute to the treatment of hypertensin in the primary care.

Tumor metabolism destruction via metformin-based glycolysis inhibition and glucose oxidase-mediated glucose deprivation for enhanced cancer therapy.

Cancer cells rely on glycolysis to support a high proliferation rate. Metformin (Met) is a promising drug for tumor treatment that targets hexokinase 2 (HK2) to block the glycolytic process, thereby further disrupting the metabolism of cancer cells. Herein, an intelligent nanomedicine based on glucose deprivation and glycolysis inhibition is creatively constructed for enhanced cancer synergistic treatment. In brief, Met and glucose oxidase (GOx) was encapsulated into histidine/zeolitic imidazolate framework-8 (His/ZIF-8), which was followed by coating with Arg-Gly-Asp (RGD) peptides to obtain the desired nanomedicine (Met/GOx@His/ZIF-8∼RGD). This smart nanomedicine presents the controllable Met and GOx release behavior in an acidic responsive manner. The liberated Met blocks the glycolysis process via suppressing the activity of HK2 and impairing ATP production, which activates the AMP-activated protein kinase (AMPK) pathway and p53 pathway and damages the Warburg effect, eventually leading to cells apoptosis. And the GOx boosts the glucose shortage for starvation therapy by depleting accumulated glucose. According to in vitro and in vivo assays, the combination of glycolysis inhibition and starvation therapy demonstrates efficient cancer cells growth suppression and superior antitumor properties compared to the Met based or GOx-mediated monotherapy. This work provides an advanced therapeutic strategy via disrupting cellular metabolism against cancer. STATEMENT OF SIGNIFICANCE: The obtained nanomedicine (Met/GOx@His/ZIF-8∼RGD) presents the controllable Met and glucose oxidase (GOx) release behavior in an acidic responsive manner. The liberated Met blocks the glycolysis process via suppressing the activity of HK2 and impairing ATP production, which activates the AMP-activated protein kinase (AMPK) pathway and p53 pathway and damages the Warburg effect, eventually leading to cells apoptosis. And the GOx boosts the glucose shortage for starvation therapy by depleting accumulated glucose. The combination of glycolysis inhibition and starvation therapy demonstrate the efficient suppression of cancer cells growth and the superior antitumor properties when compared to the Met based or GOx-mediated monotherapy.

Diabetic Heart Failure with Preserved Left Ventricular Ejection Fraction: Review of Current Pharmacotherapy.

Diabetes is associated with several diabetic-related abnormalities which increase the risk of onset or worsening of heart failure. Recent studies showed that the majority of diabetic patients present with heart failure with preserved ejection fraction (HFpEF), and the prevalence of HFpEF in diabetics is alarming. Moreover, outcomes in HFpEF are poor and could be compared to those of heart failure with reduced ejection fraction (HFrEF), with 1-year mortality ranging between 10 and 30%. In contrast to HFrEF, there is very limited evidence for pharmacologic therapy in symptomatic patients with preserved ejection fraction, and therefore, the optimal selection of treatment for diabetic HFpEF remains challenging. This narrative review article summarizes the currently available data on the pharmacological treatment of HFpEF in patients with diabetes.

High farnesoid X receptor expression predicts favorable clinical outcomes in PD­L1low/negative non­small cell lung cancer patients receiving anti­PD­1­based chemo­immunotherapy.

Anti­programmed death­1 (PD­1)/programmed death­ligand 1 (PD­L1)­directed immunotherapy has revolutionized the treatment of advanced non­small cell lung cancer (NSCLC). However, predictive biomarkers are still lacking, particularly in identifying PD­L1low/negative patients who will benefit from immunotherapy. It was previously reported that farnesoid X receptor (FXR) downregulated PD­L1 expression in NSCLC, and that FXRhighPD­L1low mouse Lewis lung carcinoma tumors showed an increased susceptibility to PD­1 blockade compared with mock tumors. At present, whether the FXRhighPD­L1low phenotype predicts clinical response to immunotherapy in patients with NSCLC remains unclear. Herein, a retrospective study was conducted to examine the expression levels of FXR, PD­L1 and CD8+ T cells by immunohistochemistry in a cohort of 149 patients with NSCLC receiving anti­PD­1­based chemo­immunotherapy. The results revealed that high FXR and PD­L1 expression levels were associated with higher objective response rates (ORR) in all patients. High PD­L1 expression also indicated superior progression­free survival (PFS). Interestingly, an inverse correlation was identified between FXR and PD­L1 expression in specimens with NSCLC. Subgroup analysis revealed that high FXR expression was associated with a higher ORR, as well as longer PFS and overall survival (OS) in PD­L1low patients. Cox multivariate analysis revealed that high FXR expression was an independent predictor for PFS and OS in PD­L1low patients. Tumor microenvironment evaluation revealed a statistically significant decrease of infiltrating CD8+ T cells in FXRhigh specimens with NSCLC. Overall, the present study proposed an FXRhighPD­L1low signature as a candidate predictor of response to anti­PD­1­based chemo­immunotherapy in PD­L1low/negative patients with NSCLC, providing evidence that could be used to broaden the patients benefitting from immunotherapy.

Tobacco Use Disorder.

Tobacco use disorder is highly prevalent; more than a billion individuals use tobacco worldwide. Popular views on the addictive potential of tobacco often underestimate the complex neural adaptations that underpin continued use. Although sometimes trivialized as a minor substance, effects of nicotine on behavior lead to profound morbidity over a lifetime of exposure. Innovations in processing have led to potent forms of tobacco and delivery devices. Proactive treatment strategies focus on pharmacotherapeutic interventions. Innovations on the horizon hold promise to help clinicians address this problem in a phenotypically tailored manner. Efforts are needed to prevent tobacco use for future generations.

Circulating tumor DNA predicts the outcome of chemotherapy in patients with lung cancer.

BACKGROUND: Circulating tumor DNA (ctDNA) has potential as a specific, noninvasive, and cost-effective new biomarker for patients with lung cancer. This study aimed to determine whether plasma ctDNA can be used to predict treatment outcomes in patients with lung cancer. METHODS: Pre- and in-treatment blood samples were collected from 14 patients with lung cancer receiving chemotherapy. Based on next-generation sequencing technology, we constructed a unique molecular identifier (UMI) library and performed targeted deep sequencing of 72 genes (15 000×). We used dVAF to evaluate the change level and trend of variant allele frequency (VAF). RESULTS: We identified MUC16, KMT2D, AMER1, and NTRK1 as the most-frequently mutated genes in ctDNA associated with lung cancer. Furthermore, we showed that the change trend of dVAF in patients with lung cancer undergoing chemotherapy was closely related to the changes in both tumor volume and tumor biomarkers, including CEA, CA125, NSE, and CK (Cytokeratin). Moreover, the ctDNA analysis revealed disease progression of SCLC patients earlier than did computed tomography. CONCLUSIONS: The dynamic detection of plasma ctDNA VAF has the potential value as a biomarker for evaluating the efficacy of chemotherapy in patients with SCLC and advanced NSCLC, and may predict the progression of lung cancer patients earlier than radiography.

A national Danish proof of concept on feasibility and safety of home -based intensive chemotherapy in patients with acute myeloid leukemia.

Technological advances have made it possible to offer home-based chemotherapy to patients without health care professionals being present. Prior studies on effects of home-based treatment lack inclusion of patients with hematologic malignancies. We present data from a multicenter single-arm feasibility and safety study of home-based intensive chemotherapy in patients with newly diagnosed acute myeloid leukemia and their quality of life and psychological wellbeing. This national study included patients from six sites in Denmark who received intensive chemotherapy on programmed CADD Solis infusion pumps through a central venous catheter and were also managed as outpatients during treatment-induced pancytopenia. Data are presented from 104 patients, receiving 272 treatments with 1.096 (mean 4.57, SD 3.0) home infusion days out of 1.644 treatment days (67 %). Sixty-two of 168 (36.9 %) reinduction and consolidation treatment cycles ensuing pancytopenia phases were solely handled in the outpatient clinic. Patients reported high satisfaction with home-based treatment, which had a positive influence on their ability to be involved in their treatment and be socially and physically active. No unexpected events occurred during the intervention. Overall, patients improved in all quality of life outcomes over time. Home-based intensive chemotherapy treatment was feasible and safe in this population. ClinicalTrials.gov identifier: NCT04904211.

Progression of chronic kidney disease in non- dialysis patients: a retrospective cohort

Abstract Evidence on factors associated with the progression of chronic kidney disease (CKD) is still under construction. The present study aimed to evaluate sociodemographic, clinical, and drug use factors associated with the progression of CKD. A retrospective cohort study was conducted with 193 patients with CKD stages 3A to 5- non-dialysis followed for three years in a Brazilian city. The outcome was the evolution to renal replacement therapy (RRT) or death. A total of 52.3 % (n = 101) were men and 83.4 % (n = 161) elderly. The median age was 72.0 years, and 22.3 % (n = 44) progressed to RRT or death, and the three-year mortality rate was 20.2 %. Participants exposed to angiotensin converting enzyme inhibitors or angiotensin II receptor blockers had a lower risk of progressing to the outcome (hazard ratio (HR) 0.25; p = 0.003) and higher survival (p = 0.022) when compared to those not exposed to these drugs. Age (HR 1.06;) and use of omeprazole (HR 6.25; CI; p <0.01) and hydrochlorothiazide (HR 2.80; p = 0.028) increased the risks of RRT or death. The results highlight the importance of rational management of pharmacotherapy for patients with CKD

Direct-acting antivirals for chronic Hepatitis C are effective and safe: an observational study in Londrina/PR

Abstract This study aimed to evaluate the effectiveness and safety of direct-acting antivirals in a Unified Health System pharmacy of Londrina, Brazil. A descriptive observational study was performed from June 2017 to June 2018. Sociodemographic, clinical, and therapeutic variables of patients were collected from secondary data sources. Effectiveness was evaluated by sustained virologic response (SVR) and safety was evaluated by adverse events (AEs) and drug interactions (DIs). The mean population (N=30) was 56.6±11.3 years old and almost all patients had comorbidities (93.3%) and concomitant drugs (96.7%). Effectiveness evaluation was possible in 17 patients, and all of them (100.0%) achieved SVR. Eighteen patients (60.0%) reported 38 AEs, mostly mild, such as stomach symptoms and headache. No statistical relation was found between AE occurrence and treatment duration, Ribavirin use, number of comorbidities or number of concomitant drugs. A total of 48 DIs were reported, 18 being severe, and were managed by the pharmacist. The study indicates that the treatment was effective and safe.

Strain longitudinal global como preditor de cardiotoxicidade induzida por quimioterapia / Global longitudinal strain as predictor of chemotherapy-induced cardiotoxicity

Fundamento: A cardiotoxicidade induzida por quimioterapia (CiC) é uma complicação importante entre os pacientes que recebem antraciclinas. Biomarcadores e parâmetros de imagem têm sido estudados por sua capacidade de identificar pacientes com risco de desenvolver essa complicação. O strain longitudinal global do ventrículo esquerdo (SLG-VE) tem sido descrito como um parâmetro sensível para detectar disfunção sistólica, mesmo na presença de fração de ejeção do ventrículo esquerdo (FEVE) preservada. Objetivo: avaliar o papel do SLG-VE como preditor de CiC. Métodos: O presente estudo consiste em uma análise post-hoc do estudo CECCY (Carvedilol for Prevention of ChemotherapyRelated Cardiotoxicity [Carvedilol para Prevenção da Cardiotoxicidade Relacionada à Quimioterapia]), que avaliou a prevenção primária de cardiotoxicidade com carvedilol durante quimioterapia com doxorrubicina em uma população com câncer de mama. Definiu-se cardiotoxicidade como uma redução >10% na FEVE. O SLG-VE foi obtido antes da quimioterapia em pacientes sem doença cardiovascular prévia ou anormalidades no ecocardiograma. Resultados: Trinta e um pacientes submetidos a estudo ecocardiográfico completo incluindo avaliação de SLG-VE antes da quimioterapia foram incluídos nesta análise. Um SLG-VE absoluto <16,9% antes da quimioterapia mostrou 100% de sensibilidade e 73% de especificidade para predizer cardiotoxicidade (AUC=0,85; IC 95% 0,680­0,959, p<0,001). Nesta população, os valores de FEVE antes da quimioterapia não foram preditores de CiC (IC 95% 0,478 a -0,842, p=0,17). A associação de baixos níveis séricos de SLG-VE (<17%) e BNP (>17 pg/mL) dois meses após a quimioterapia aumentou a precisão para detectar CiC de início precoce (100% de sensibilidade, 88% de especificidade, AUC=0,94; IC 95% 0,7810,995, p<0,0001). Conclusões: Nossos dados sugerem que o SLG-VE é um possível preditor de cardiotoxicidade induzida por quimioterapia. São necessários estudos maiores para confirmar a relevância clínica desse parâmetro ecocardiográfico nesse cenário clínico. (AU)

Background: Chemotherapy-induced cardiotoxicity (ChC) is an important complication among patients receiving anthracyclines. Biomarkers and imaging parameters have been studied for their ability to identify patients at risk of developing ChC. Left ventricular global longitudinal strain (LV-GLS) is a sensitive parameter for detecting systolic dysfunction despite the presence of preserved left ventricular ejection fraction (LVEF). Objective: To evaluate the role of the LV-GLS as a predictor of ChC. Methods: This was a post-hoc analysis of the Carvedilol for Prevention of Chemotherapy-Related Cardiotoxicity trial, which evaluated the primary prevention of cardiotoxicity with carvedilol during doxorubicin chemotherapy in a population of patients with breast cancer. Cardiotoxicity was defined as a reduction ≥10% in LVEF. LV-GLS was determined before chemotherapy in patients with no prior cardiovascular disease or echocardiogram abnormalities. Results: Thirty-one patients for whom a complete echocardiography study including measurement of LV-GLS was performed before chemotherapy were included in this analysis. An absolute LV-GLS<16.9% before chemotherapy showed 100% sensitivity and 73% specificity for predicting cardiotoxicity (area under the curve [AUC], 0.85; 95% confidence interval [CI], 0.680­0.959; p<0.001). In this population, LVEF values before chemotherapy did not predict ChC (95% CI, 0.478 to -0.842; p=0.17). The association of low LV-GLS (<17%) and brain-type natriuretic peptide serum levels (>17 pg/mL) at 2 months after chemotherapy increased the accuracy for detecting early-onset ChC (100% sensitivity, 88% specificity; AUC, 0.94; 95% CI, 0.781­0.995; p<0.0001). Conclusions: Our data suggest that LV-GLS is a potential predictor of ChC. Larger studies are needed to confirm its clinical relevance in this clinical setting. (AU)

Risk factors and pharmacotherapy for chemotherapy-induced peripheral neuropathy in paclitaxel-treated female cancer survivors: A retrospective study in Japan.

Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting adverse reaction in cancer patients treated with several cytotoxic anticancer agents including paclitaxel. Duloxetine, an antidepressant known as a serotonin-noradrenalin reuptake inhibitor, is the only agent that has moderate evidence for the use to treat painful CIPN. The present retrospective cohort study aimed to analyze risk factors for paclitaxel-induced peripheral neuropathy (PIPN), and investigate ongoing prescription drug use for PIPN in Japan. Female breast and gynecologic cancer patients who underwent paclitaxel-based chemotherapy at a single center in Japan between January 2016 and December 2019 were enrolled in this study. Patients' information obtained from electronic medical records were statistically analyzed to test possible risk factors on PIPN diagnosis. Patients' age, total paclitaxel dose, the history of female hormone-related diseases, hypertension and body mass index (BMI), but not additional platinum agents, were significantly associated with increased PIPN diagnosis. Drugs prescribed for PIPN included duloxetine, pregabalin, mecobalamin and Goshajinkigan, a polyherbal medicine, regardless of poor evidence for their effectiveness against CIPN, and were greatly different between breast and gynecologic cancer patients diagnosed with PIPN at the departments of Surgery and Gynecology, respectively. Thus, older age, greater total paclitaxel dose, the history of estrogen-related diseases, hypertension and BMI are considered risk factors for PIPN in paclitaxel-based chemotherapy of female cancer patients. It appears an urgent need to establish a guideline of evidence-based pharmacotherapy for PIPN.
