Experiences of family members of cancer patients in palliative care: a qualitative systematic review protocol.

OBJECTIVE: The objective of this review is to synthesize the experiences of family members of cancer patients in palliative care. INTRODUCTION: Increasingly, palliative care is the approach advocated when a life-threatening illness has been diagnosed. Cancer patients and their families, when receiving early identification, correct assessment, and treatment of pain and other problems through palliative care, report feeling supported in their illness experience. The patients and their families also describe immediate and personalized symptom management, holistic support, decision-making guidance, and preparation for the future, including the dying process and stages of grief. A growing number of studies address palliative care patients and, in particular, the central role of family in this approach. This review will synthesize qualitative research on this subject, providing recommendations to health professionals to help them better understand the experiences and needs of family members of cancer patients receiving palliative care. INCLUSION CRITERIA: The review will consider studies examining experiences of families of cancer patients in palliative care, in all types of settings and contexts. The studies will focus on qualitative data, including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research, qualitative descriptive, and mixed methods studies. METHODS: The review will follow the JBI methodology for systematic reviews of qualitative evidence. The search strategy will aim to locate both published and unpublished studies, in any language, with no date restrictions. Methodological quality will be evaluated using the standard JBI critical appraisal checklist for qualitative research. The findings will be pooled using the meta-aggregation approach or will be presented in narrative format. The final synthesized findings will be graded according to the ConQual approach. REVIEW REGISTRATION: PROSPERO CRD42022333937.

Liver stiffness regression after sustained virological response by direct-acting antivirals reduces the risk of outcomes.

The role of liver stiffness measurement (LSM) after sustained virological response (SVR) in HCV patients treated by direct-acting antivirals (DAAs) remains unclear. We aimed to evaluate LSM regression value after SVR and to identify risk factors associated with liver related complications (LRC) or death. This retrospective study analyzed patients with LSM ≥ 10 kPa with LSM by transient elastography pre-DAAs and post-SVR. Patients with previous hepatic decompensation were excluded. Medical records were reviewed to identify primary outcomes. Kaplan-Meier curves and time-to-event Cox proportional-hazard models were performed. 456 patients [65% female, 62 years (IQR 57-68)] were included. During a follow-up of 2.3 years (IQR 1.6-2.7), 28 patients developed 37 outcomes [rate = 29.0 (95% CI 20.0-42.0) per 1000 person-years]. The cumulative incidence of outcomes was significantly lower in patients who regressed LSM ≥ 20% [3.4% (95% CI 1.8-7.0) vs. 9.0% (5.5-14.5), p = 0.028]. In a multivariate Cox-model [HR(95% CI)], male gender [HR = 3.00 (1.30-6.95), p = 0.010], baseline albumin < 3.5 mg/dL [HR = 4.49 (1.95-10.34), p < 0.001] and baseline unfavorable Baveno-VI [HR = 4.72 (1.32-16.83), p = 0.017] were independently associated and LSM regression ≥ 20% after SVR had a trend to reduce the risk of LRC or death [HR = 0.45 (0.21-1.02), p = 0.058]. The use of simple parameters before DAAs and repetition of LSM post-SVR can identify patients with different risks for severe outcome after HCV eradication.

Effectiveness of direct-acting agents for hepatitis C and liver stiffness changing after sustained virological response.

BACKGROUND AND AIM: Few studies have evaluated sustained virological response (SVR) rates by direct-acting agents (DAAs) and liver stiffness measurement (LSM) changing post-SVR in limited-resource settings. We aimed to describe the effectiveness of DAAs for hepatitis C virus treatment and to assess the changing of LSM post-SVR. METHODS: This retrospective study analyzed data of consecutive hepatitis C virus-infected patients treated by DAAs from 2015 to 2017 in two tertiary centers in Brazil. SVR rates were reported by intention-to-treat and per-protocol analyses. LSM by transient elastography performed before treatment and post-SVR was compared, and logistic regression models were performed. RESULTS: Six hundred seventy-one patients (63% female, 62 years [55-68], 89% genotype 1, 8% HIV co-infected, and 64% with cirrhosis) were included. Most patients were treated by sofosbuvir/daclatasvir ± ribavirin (74%) and sofosbuvir/simeprevir ± ribavirin (21%). SVR rates (95% confidence interval [CI]) were 94.6% (92.7-96.1) and 97.8% (96.4-98.7) for intention-to-treat and per-protocol analyses, respectively. The leading adverse event was anemia (9.6% [95% CI 7.6-12.1]). Pretreatment and post-SVR12 LSM were available in 400 patients. LSM had significantly decreased after SVR (13.6 kPa [interquartile range, 10.0-21.6] vs 10.2 kPa [7.0-17.6], P < 0.001). A total of 167 patients (42%) decreased at least 30% of LSM post-SVR. The absence of type 2 diabetes (odds ratio = 1.52 [95% CI 1.05-2.21], P = 0.028) and presence of platelet count ≥ 150 × 109 /mm3 (odds ratio = 1.75 [1.23-2.50], P = 0.002) were independently associated with a significant LSM regression (≥ 30%) post-SVR. CONCLUSION: DAAs were highly effective and safe, and LSM significantly decreased after SVR in a real-life cohort in Brazil. The absence of type 2 diabetes and presence of high platelet count were independently associated with LSM decrease post-SVR.

Pomolic acid induces apoptosis and inhibits multidrug resistance protein MRP1 and migration in glioblastoma cells.

Glioblastoma (GBM), the most aggressive of primary brain tumors, determine short survival and poor quality of life. Therapies used for its treatment are not effective and chemotherapy failure is partially due to multidrug resistance (MDR) mechanisms present in the tumor cells. New therapeutic strategies are needed in order to improve survival in GBM. The present study investigated the activity of the pentacyclic triterpene pomolic acid (PA) in GBM. Pomolic acid decreased the viability and induced apoptosis of GBM cells as demonstrated by DNA fragmentation. It also induced uncoupling of mitochondria membrane potential and activation of caspase-3 and -9. Pomolic acid-induced apoptosis is dependent on reactive oxygen species (ROS) production as it is inhibited by anti-oxidant treatment. Pomolic acid also down-modulated the activity of the multidrug resistance associated protein 1 (MRP1) and inhibited migration of GBM cells. These results show that PA acts on several pathways of GBM drug resistance and therefore may be of potential interest for the treatment of this tumor.

Apoptosis-inducing effects of Melissa officinalis L. essential oil in glioblastoma multiforme cells.

Current therapies for glioblastoma multiforme (GBM) are not effective. This study investigated the activity of the M. officinalis essential oil (EO) and its major component (citral) in GBM cell lines. Both EO and citral decreased the viability and induced apoptosis of GBM cells as demonstrated by DNA fragmentation and caspase-3 activation. Antioxidant prevented citral-induced death, indicating its dependence on the production of reactive oxygen species. Citral downmodulated the activity and inhibited the expression of multidrug resistance associated protein 1 (MRP1). These results show that EO, through its major component, citral, may be of potential interest for the treatment of GBM.

Cardiotoxicidade induzida por quimioterápicos: [revisão] / Chemotherapy induced cardiotoxicity: [review]

A sobrevida dos pacientes com câncer aumentou consideravelmente nos últimos 20 anos e, com ela,o número de eventos adversos associados aos quimioterápicos. A cardiotoxicidade crônica induzida pelos agentes antineoplásicos pode comprometer a sobrevida e a qualidade de vida dos pacientes, independentemente de seu prognóstico oncológico. Inúmeros fármacos foram associados a eventos adversos cardiovasculares, e até o momento não há protocolos bem estabelecidos para se detectar precocemente a toxicidade cardíaca. Alguns métodos auxiliam o diagnóstico, como o ecocardiograma, a dosagem de marcadores bioquímicos como a troponina I e o peptídeo natriurético, e a biópsia endomiocárdica. A cardiotoxicidade induzida por quimioterápicos tem se mostrado irreversível e ,uma vez estabelecida a disfunção miocárdica, seu tratamento independe do agente associado à indução da lesão. Estudos recentes sugerem o papel de agentes específicos como o dexrazoxane, a eritropoietina, a trombopoietina e os inibidores da enzima conversora de angiotensina na prevenção do desenvolvimento de cardiotoxicidade relacionada à quimioterapia.

Life expectancy of cancer patients has considerably increased in the last 20 years, but adverseevents associated to chemotherapy have also been more frequent. Chronic cardiactoxicity of antineoplastic agents can compromise survival and quality of life, independentof the oncological prognosis. A wide range of chemotherapy drugs have been associatedto cardiovascular adverse events, and until nowadays there are no well establishedprotocols for early detection of cardiac toxicity. Some methods help in identifying initialcardiomyopathy, such as the echocardiogram, the biochemical markers troponin I andnatriuretic peptide, and endomiocardial biopsy. Chemotherapy induced cardiotoxicityseems to be irreversible, and once myocardial dysfunction is established, the treatmentis not dependent of the causative drug. Recent studies suggest a role for specific agentssuch as dexrazoxan, eritropoietin, thrombopoietin and angiotensin converting enzymeinhibitors in preventing chemotherapy induced cardiotoxicity.

Choque cardiogênico na miocardiopatia induzida por agentes antineoplásicos: relato de caso / Cardiogenic shock in cardiomyopathy induced by antineoplastic agents: a case report

No Brasil, a principal etiologia da insuficiência cardíaca (IC) é a cardiopatia isquêmica crônica associada à hipertensão arterial. A IC pode se manifestar como doença crônica estável ou descompensada. A IC descompensada pode se apresentar como edema agudo de pulmão ou choque cardiogênico no atendimento de urgência. Este trabalho descreve a evolução de paciente admitida em unidade de pronto-socorro com choque cardiogênico secundário à miocardiopatia induzida por agentes antineoplásicos, manifesta quatro anos após a quimioterapia para câncer de mama.

The main cause of heart failure (HF) in Brazil is ischemic cardiomyopathy associated to arterial hypertension. HF can present as a chronic stable or as a decompensated disease. Decompensated HF can manifest as acute pulmonary edema and cardiogenic shock in the emergency unit. We describe here a patient admitted to an emergency room with cardiogenic shock secondary to cardiomyopathy induced by antineoplastic agents, 4 years after chemotherapy for breast cancer.
