RESUMO

BACKGROUND: Approximately 18% of patients with cancer use cannabis at one time as palliation or treatment for their cancer. We performed a systematic review of randomized cannabis cancer trials to establish a guideline for its use in pain and to summarize the risk of harm and adverse events when used for any indication in cancer patients. METHODS: A systematic review of randomized trials with or without meta-analysis was carried out from MEDLINE, CCTR, Embase, and PsychINFO. The search involved randomized trials of cannabis in cancer patients. The search ended on November 12, 2021. The Jadad grading system was used for grading quality. Inclusion criteria for articles were randomized trials or systematic reviews of randomized trials of cannabinoids versus either placebo or active comparator explicitly in adult patients with cancer. RESULTS: Thirty-four systematic reviews and randomized trials met the eligibility criteria for cancer pain. Seven were randomized trials involving patients with cancer pain. Two trials had positive primary endpoints, which could not be reproduced in similarly designed trials. High-quality systematic reviews with meta-analyses found little evidence that cannabinoids are an effective adjuvant or analgesic to cancer pain. Seven systematic reviews and randomized trials related to harms and adverse events were included. There was inconsistent evidence about the types and levels of harm patients may experience when using cannabinoids. CONCLUSION: The MASCC panel recommends against the use of cannabinoids as an adjuvant analgesic for cancer pain and suggests that the potential risk of harm and adverse events be carefully considered for all cancer patients, particularly with treatment with a checkpoint inhibitor.

RESUMO

BACKGROUND: Drug utilisation studies are relevant for the analysis of prescription rationality and are pertinent in today's context of the increasing burden of antimicrobial resistance. Prescriptions for patients with diarrhoea or Acute Respiratory Infection (ARI) have been analysed in this study to understand the prescription pattern among various categories of prescribers in two tertiary care centers. METHODS: This cross-sectional study was conducted from August 2019 to December 2020 in the medicine and pediatrics outpatient departments of two government teaching hospitals in West Bengal, India. A total of 630 prescriptions were evaluated against WHO standards. Prescriptions were assessed by a 'Rational Use of Medicine Consensus committee' approach. RESULTS: The Fixed Dose Combination (FDC) was used in half of the patients (51%). Both the generic prescription (23.3%) and adherence to hospital formulary rates (36.5%) were low. The antibiotics prescription rate was high (57%), and it was higher for diarrhoea than ARI. Deviations from the standard treatment guidelines were found in 98.9% of prescriptions. Deviations were commonly found with prescriptions written by the junior doctors (99.6%). CONCLUSION: Irrational prescribing patterns prevail in tertiary care centers and indicate the necessity of awareness generation and capacity building among prescribers regarding AMR and its unseen consequences.

RESUMO

PURPOSE: During the treatment of cancer, 18% of patients use cannabis for symptom management. Anxiety, depression, and sleep disturbances are common symptoms in cancer. A systematic review of the evidence for cannabis use for psychological symptoms in cancer patients was undertaken to develop a guideline. METHODS: A literature search of randomized trials and systematic reviews was undertaken up to November 12, 2021. Studies were independently assessed for evidence by two authors and then evaluated by all authors for approval. The literature search involved MEDLINE, CCTR, EMBASE, and PsychINFO databases. Inclusion criteria included randomized control trials and systematic reviews on cannabis versus placebo or active comparator in patients with cancer and psychological symptom management (anxiety, depression, and insomnia). RESULTS: The search yielded 829 articles; 145 from Medline, 419 from Embase, 62 from PsychINFO, and 203 from CCTR. Two systematic reviews and 15 randomized trials (4 on sleep, 5 on mood, 6 on both) met eligibility criteria. However, no studies specifically assessed the efficacy of cannabis on psychological symptoms as primary outcomes in cancer patients. The studies varied widely in terms of interventions, control, duration, and outcome measures. Six of 15 RCTs suggested benefits (five for sleep, one for mood). CONCLUSION: There is no high-quality evidence to recommend the use of cannabis as an intervention for psychological symptoms in patients with cancer until more high-quality research demonstrates benefit.

RESUMO

BACKGROUND: Gastrointestinal symptoms are common in patients with cancer, whether related to treatment or a direct effect of the disease itself. Patients may choose to access cannabinoids outside of their formal medical prescriptions to palliate such symptoms. However, clinical guidelines are lacking in relation to the use of such medicines for gastrointestinal symptoms in patients with cancer. METHODS: A systematic review of the evidence for the use of cannabinoids for symptom control in patients with cancer was undertaken. Search strategies were developed for Medline, Embase, PsychINFO, and the Cochrane Central Register of Controlled Trials, including all publications from 1975 up to 12 November 2021. Studies were included if they were randomized controlled trials of cannabinoids compared with placebo or active comparator in adult patients with cancer, regardless of type, stage, or treatment status. Articles for inclusion were agreed by all authors, and data extracted and summarized by two authors. Each study was scored according to the Jadad scale. This review was specifically for the purpose of developing guidelines for the use of cannabis for gastrointestinal symptoms, including chemotherapy-induced nausea and vomiting (CINV), chronic nausea, anorexia-cachexia syndrome, and taste disturbance. RESULTS: Thirty-six randomized controlled trials were identified that met the inclusion criteria for this review of gastrointestinal symptoms: 31 relating to CINV, one to radiotherapy-induced nausea and vomiting, and the remaining four to anorexia-cachexia and altered chemosensory disturbance. The populations for the randomized controlled trials were heterogeneous, and many studies were of poor quality, lacking clarity regarding method of randomization, blinding, and allocation concealment. For CINV, eleven RCTs showed improvement with cannabis compared to placebo, but out of 21 trials where cannabis was compared to other antiemetics for CINV, only 11 favoured cannabis. CONCLUSION: Tetrahydrocannabinol (THC) and nabilone were more effective in preventing CINV when compared to placebo but are not more effective than other antiemetics. For refractory CINV, one study of THC:CBD demonstrated reduced nausea as an add-on treatment to guideline-consistent antiemetic therapy without olanzapine. The MASCC Guideline Committee found insufficient evidence to recommend cannabinoids for the management of CINV, nausea from advanced cancer, cancer-associated anorexia-cachexia, and taste disturbance. High-quality studies are needed to inform practice.

RESUMO

Examining and addressing unmet care needs is integral to improving the provision and quality of cancer services. This review explored the prevalence of unmet supportive care needs, and factors associated with unmet need, in adults with advanced cancers (solid and hematological malignancies) and their caregivers. Electronic databases (PubMed, CINAHL, EMBASE) were searched, producing 85 papers representing 81 included studies. People with advanced cancer reported the highest unmet needs in financial, health system and information, psychological, and physical and daily living domains, whereas caregivers reported the highest unmet needs in psychological, and patient care and support domains. Distress, depression, and anxiety were associated with higher unmet needs across all unmet need domains for people with advanced cancer and their caregivers. Substantial heterogeneity in study populations and methods was observed. Findings from this review can inform targeted strategies and interventions to address these unmet needs in people with advanced cancer.

RESUMO

Background: Granulocyte-colony stimulating factor (G-CSF) is used in cancer patients to treat chemotherapy-induced neutropenia (CIN). However, G-CSF poses few risks. Despite the regular use of G-CSF in CIN management, there is a paucity of published data on its safety profile in the management of CIN in India. Hence, the present study was designed to demonstrate the safety profile of G-CSF in patients with CIN. Methods: A prospective observational study was conducted over a period of 5 months enrolling 100 cancer patients aged from 18 years to 70 years. Patients with a diagnosis of CIN who received G-CSF were included. Patients were followed up for 15 days. Adverse events (AEs) were graded according to US National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The system organ class and preferred term of Medical Dictionary for Regulatory Activities (MedDRA) were used for reporting the AEs. Causality assessment was done by using the WHO-Uppsala Monitoring Centre scale. Results: The most frequently reported AEs were musculoskeletal and connective tissue disorders which included bone pain, myalgia, arthralgia, and pain in the extremity. Other AEs reported were general disorders and administration site conditions, and gastrointestinal disorders. The highest grade of toxicity reported was of grade 3 among all AEs. The majority of AEs had a "probable" type of causality relationship with G-CSF. Conclusion: ">G-CSF has a safety profile consistent with previous G-CSF studies.

RESUMO

PURPOSE: The pro vision of clinically assisted nutrition (CAN) in patients with advanced cancer is controversial, and there is a paucity of specific guidance, and so a diversity in clinical practice. Consequently, the Palliative Care Study Group of the Multinational Association of Supportive Care in Cancer (MASCC) formed a Subgroup to develop evidence-based guidance on the use CAN in patients with advanced cancer. METHODS: This guidance was developed in accordance with the MASCC Guidelines Policy. A search strategy for Medline was developed, and the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials were explored for relevant reviews/trials respectively. The outcomes of the review were categorised by the level of evidence, and a "category of guideline" based on the level of evidence (i.e. "recommendation", "suggestion", or "no guideline possible"). RESULTS: The Subgroup produced 11 suggestions, and 1 recommendation (due to the paucity of evidence). These outcomes relate to assessment of patients, indications for CAN, contraindications for CAN, procedures for initiating CAN, and re-assessment of patients. CONCLUSIONS: This guidance provides a framework for the use of CAN in advanced cancer, although every patient needs individualised management.

RESUMO

Aims: Comparison of efficacy, safety and sedation between two doses of olanzapine in the control of chemotherapy-induced nausea and vomiting (CINV). Patients & methods: A prospective, randomized, double-blind, controlled study was conducted, enrolling 68 patients receiving a single-day cycle of high and moderately emetogenic chemotherapy. Patients received either of olanzapine 5 mg or 10 mg from day 1 through 3 in addition to ondansetron and dexamethasone. Control of CINV, nausea, sedation, quality of life (QoL) and adverse events were compared. Results: Nausea, emesis control and improvement of QoL were similar in both groups. Sedation severity was 133% higher with 10 mg olanzapine. Conclusions: Lower dose olanzapine is effective to control CINV with significantly reduced sedation.


Lay abstract Methods to prevent chemotherapy-induced nausea and vomiting (CINV) are often not sufficient for patients. Olanzapine, along with other similar drugs (antiemetics), improved control but is often sedating. In this study, a lower dose of olanzapine was compared with the conventional dose. Patients on cancer chemotherapy, which has high occurrence of nausea and vomiting, were given either the low dose or the conventional dose of olanzapine for 3 days, in addition to some other antiemetic agents. Control of nausea and vomiting was reasonably achieved with both doses of olanzapine. The lower dose was significantly less sedating. There were no serious side effects with either doses.

RESUMO

The aim of this study was to compare the efficacy and safety of modafinil and dexamethasone in the management of cancer-related fatigue and their effects on quality of life (QoL). A prospective randomized controlled study was conducted, enrolling 80 cancer patients experiencing moderate or severe fatigue following at least three cycles of chemotherapy or a course of palliative/curative radiotherapy. Patients received either oral modafinil 100 mg or dexamethasone 4 mg daily for 14 days. Levels of fatigue, QoL and symptom severity were compared after 14-21 days. Both drugs were efficacious and safe in the management of fatigue and QoL. However, modafinil performed marginally better. Although modafinil demonstrated marginal superiority, both modafinil and dexamethasone can improve fatigue and QoL in cancer patients. Clinical trials registry of India: CTRI/2018/05/014046 (www.ctri.nic.in).


Lay abstract Cancer-related fatigue is a common and nagging problem that needs best evidence-based management. Modafinil, a brain stimulant, and dexamethasone, a corticosteroid, have been shown in separate studies to provide benefit, but there are little data regarding which one is superior. The present study compared modafinil with dexamethasone in a randomized controlled trial. Modafinil was found to be marginally superior in treating cancer-related fatigue and several domains of quality of life, though dexamethasone also demonstrated significant improvement of fatigue. This study provides a valuable guide for future larger studies for implementation of the findings in the form of better patient care.

RESUMO

Arsenic toxicity is the most commonly experienced challenge of rice plants due to irrigation with arsenic-polluted groundwater and their cultivation in water logging environment which poses threat to human health, particularly in Bangladesh and West Bengal (India). In the present study, hydroponically grown eight rice cultivars, viz., Bhutmuri, Kumargore, Binni, Vijaya, Tulsibhog, Badshabhog, Pusa basmati, and Swarnadhan, were screened for arsenic tolerance by using physiological and molecular parameters. Treatment with 25 µM, 50 µM, and 75 µM arsenate resulted in dosage-based retardation in growth and water content in all the tested cultivars due to accumulation of total arsenic along with the enhanced activity of arsenate reductase with more severe effects exhibited in cvs. Swarnadhan, Pusa basmati, Badshabhog, and Tulsibhog. Arsenic sensitivity of rice cultivars was evaluated in terms of oxidative stress markers generation, antioxidant enzyme activities, and level of genotoxicity. Under arsenate-challenged conditions, the levels of oxidative stress markers, viz., H2O2, MDA, and proline, and activities of antioxidant enzymes, viz., SOD and CAT, along with the level of genotoxicity analyzed by RAPD profiling were altered in variable levels in all tested rice cultivars and showed a significant alteration in band patterns in arsenate-treated seedlings of cvs. Swarnadhan, Pusa basmati, Badshabhog, and Tulsibhog in terms of appearance of new bands and disappearance of normal bands that were presented in untreated seedlings led to reduction in genomic template stability due to their high susceptibility to arsenic toxicity. Cultivar- and dose-dependent alteration of parameters tested including the rate of As accumulation showed that cvs. Kumargore, Binni, and Vijaya, specially Bhutmuri, were characterized as arsenate tolerant and could be cultivated in arsenic-prone areas to minimize level of toxicity and potential health hazards.

RESUMO

Background : Several studies have provided evidence of CD4+ and CD8+ lymphocyte infiltration in various malignancies with probable implications for prognosis. Cervical cancer accounts for a major part of the cancer burden in the developing world. Study of genetically and ethnically diverse Indian cervical cancer patients is necessary to assess effects on lymphocytic infiltration of tumour tissue. Methods : This observational study was conducted over a period of 12 months with selected cervical cancer patients meeting inclusion criteria. Samples of cervical cancer tissue and peripheral blood were obtained and tumour infiltration with CD4+ and CD8+ lymphocytes was noted. Cell numbers were quantified by flow-cytometry and proportions compared between tumour and peripheral blood samples. Results: Tumour infiltration was noted with both CD4+ (13.93±10.95) and CD8+ (19.5±12.05) lymphocyte subtypes. However, compared to peripheral blood, CD4+ cells were significantly less predominant in tumour tissue (p, 0.0013). There was a statistically significant (p, 0.0004) reversal of the ratio of CD4+ and CD8+ in the tumour tissue (0.68±0.39) compared to peripheral blood (1.5±0.66) with maximal alteration in higher stage disease. Conclusion : The study revealed that T lymphocyte infiltration of cervical cancer tissue occurs but the ratio of CD4+ to CD8+ subtypes is sifnificantly lower than in peripheral blood, especially with in advanced stages of disease. The clinical implications of such a reversal of CD4+ and CD8+ ratios is unknown, but might have prognostic significance.

RESUMO

PURPOSE: Even with the use of modern antiemetic drugs, chemotherapy-induced nausea and vomiting (CINV) is still a cause of great distress to the patients. Olanzapine, primarily marketed as an antipsychotic, was found to reduce nausea and vomiting in some chemotherapy patients. But it was never tested in Indian population with a diverse genetic background. The present study aims to evaluate the role of olanzapine in CINV in patients receiving platinum-based chemotherapy. METHODS: The study was a randomized, controlled, assessor-blinded study on 100 chemotherapy-naïve consenting patients receiving any one from cisplatin, carboplatin or oxaliplatin. The control group (n = 50) received palonosetron and dexamethasone in the approved therapeutic dose from the day 1 of chemotherapy. The test group (n = 50) received additional olanzapine 10 mg/day from day 1 for five consecutive days. CINV and quality of life (QoL) were assessed. RESULTS: Vomiting was significantly less among the olanzapine-treated patients. Control of delayed emesis was significantly better in this group (complete response among 96 vs. 42 % in the control group, p value <0.0001). Incidence and severity of nausea was significantly less in this group. Failure of anti-CINV measure was 4 % in this group compared to 26 % of the patients of the control group during overall days 1-5. Though sedation was more in these olanzapine-treated patients, there was no dose-limiting adverse event. Quality of life was also better among the olanzapine-treated patients. CONCLUSION: Olanzapine was found to be effective as add-on in the control of CINV.

RESUMO

BACKGROUND: Breast cancer is the most common malignancy of women in the world. The disease is caused by infectious and non-infectious, environmental and lifestyle factors. Tobacco smoke has been one of the most widely studied environmental factors with possible relevance to breast cancer. The purpose of this study was to assess the impact of tobacco smoking in breast cancer patients in a hospital based cohort and to establish prognostic implications if any. MATERIALS AND METHODS: A retrospective audit of 100 women with pathological diagnosis of invasive breast cancer was included in this study. The verbal questionnaire elicited information on current and previous history of exposure to smoking in addition to active smoking. All analyses were adjusted for potential confounders, including stage at presentation, alcohol intake, hormonal replacement therapy, oral contraceptive intake, obesity and menopausal status. RESULTS: The mean age at presentation of breast cancer was 51.4 ± 10.86 years. Mean age of presentation was 53.1±11.5 and 45.7±11.9 years in never smokers and passive smokers, respectively. Age at presentation varied widely in patients exposed to tobacco smoke for >10 years in childhood from 40.3± 12.0 years to 47.7± 13.9 in patients exposed for > 20 years as adults. Among passive smokers, 60.9% were premenopausal and 39.1% of patients were postmenopausal. In never smokers, 71.4% were post menopausal. Expression of receptors in non-smokers vs passive smokers was comparable with no significant differences. Metastatic potential in lung parenchyma was slightly elevated in passive smokers as compared to never smokers although statistically non-significant. CONCLUSIONS: An inverse relationship exists between the intensity and duration of smoking and the age at presentation and poor prognostic factors. The results strongly suggest efforts should be taken to prevent smoking, encourage quitting and restrict exposure to second hand smoke in India.

RESUMO

Washing soda is chemically known as sodium carbonate and is a component of laundry detergent. Domestic effluent, drain water and various anthropogenic activities have been identified as major routes of sodium carbonate contamination of the freshwater ecosystem. The freshwater sponge, Eunapius carteri, bears ecological and evolutionary significance and is considered as a bioresource in aquatic ecosystems. The present study involves estimation of morphological damage, lysosomal membrane integrity, activity of phosphatases and apoptosis in the cells of E. carteri under the environmentally realistic concentrations of washing soda. Exposure to washing soda resulted in severe morphological alterations and damages in cells of E. carteri. Fragility and destabilization of lysosomal membranes of E. carteri under the sublethal exposure was indicative to toxin induced physiological stress in sponge. Prolonged exposure to sodium carbonate resulted a reduction in the activity of acid and alkaline phosphatases in the cells of E. carteri. Experimental concentration of 8 mg/l of washing soda for 192 h yielded an increase in the physiological level of cellular apoptosis among the semigranulocytes and granulocytes of E. carteri, which was suggestive to possible shift in apoptosis mediated immunoprotection. The results were indicative of an undesirable shift in the immune status of sponge. Contamination of the freshwater aquifers by washing soda thus poses an alarming ecotoxicological threat to sponges.

RESUMO

BACKGROUND AND AIMS: In absence of any published standard guideline for sedation or anesthesia practice for prolonged therapeutic "endoscopic retrograde cholangio-pancreatography (ERCP)", safe and cost-effective sedation protocol is the need of the hour. Our study aims to evaluate the efficacy of a dexmedetomidine as an add-on for prolonged deep sedation for ERCP and to compare three deep sedation regimens regarding safety and efficacy. MATERIAL AND METHODS: Forty-five consecutively enrolled patients planned for therapeutic ERCP and assumed to have prolonged procedural duration (>50 min) were divided into three groups in a randomized assessor blinded fashion. Group 1 received propofol and midazolam, Group 2 received the sedato-analgesic cocktail containing ketamine-propofol-midazolam-pentazocine, and the Group 3 received sedate-analgesic cocktail plus dexmedetomidine infusion under monitoring of vital parameters and according to the judgment of the concerned anesthesiologist. Total propofol requirement, episodes of gagging, oxygen desaturation, changes in mean blood pressure (MBP), recovery and satisfaction score of endoscopist, anesthetist and patient were noted and analyzed statistically using one way ANOVA with Bonferroni correction and Chi-square test. RESULTS: Mean propofol requirement, incidences of gagging and oxygen desaturation was significantly less in Group 2 and 3 compared to Group 1. MBP was more stable and recovery was faster in Group 3. Anesthetist's satisfaction was more with Group 2 and even more with Group 3. CONCLUSIONS: The sedato-analgesic cocktail was superior to the conventional propofol-midazolam regimen, dexmedetomidine as add-on increased the efficacy and safety of sedate-analgesic cocktail. It reduces propofol requirement, helps to maintain the patient in a safe and more stable level of sedation and increases satisfaction of the anesthetist.

RESUMO

PURPOSE: Patients undergoing middle ear surgery experience variable degrees of postoperative nausea and vomiting (PONV) despite prophylaxis and treatment with ondansetron or other 5HT3 receptor antagonists. Furthermore vertigo or dizziness are not well controlled perioperatively. Role of betahistine was tested as an add-on to ondansetron in control of PONV and vertigo in middle ear surgery cases. MATERIALS AND METHODS: We conducted a prospective, randomized, double-blind, placebo controlled study, enrolling one hundred patients undergoing middle ear surgery under local anesthesia into two groups consisting of fifty (n = 50) patients each. Group A patients were given betahistine 16 mg plus ondansetron 8 mg and placebo plus ondansetron 8 mg were given to group B or placebo group, orally 3 hours before starting operation. The incidence of nausea, vomiting, and dizziness was noted during the intraoperative and postoperative 24 hours period. Chi-square test, unpaired 't' test, and Fisher's exact tests were performed for statistical analysis using SPSS version 16 and Open Epi version 2.3.1 softwares. RESULTS: Complete response was obtained in 90% patients in the betahistine group as compared to 66% in the placebo group. Vomiting in the intraoperative and postoperative period was noted in 4% and 8% cases, respectively, in the betahistine group as compared to 18% and 26%, respectively, in the placebo group. Overall, vertigo was 10% versus 32% in betahistine group and placebo group, respectively. CONCLUSION: Betahistine as an add-on to ondansetron can significantly attenuate PONV and perioperative vertigo, following middle ear surgeries.

RESUMO

BACKGROUND: General anesthesia is commonly used for surgery in the neck region. Superficial cervical plexus block is adequate to produce anesthesia in the anterior and anterolateral aspects of the neck. Our aim was to observe the effectiveness of bilateral cervical plexus block for surgery in this region of the neck. METHODS: A total of 136 neck surgery cases were enrolled in this prospective uncontrolled study. All patients were administered ropivacaine 0.5% as a bilateral cervical plexus block. The incision line was infiltrated with lignocaine 1% and adrenaline 1:100,000. For thyroglossal cyst and thyroglossal fistula, an additional 1.5 mL of LA solution was deposited over the hyoid bone on both sides of the midline. Any anesthetic inadequacy was corrected using ketamine 25 mg intravenously and repeated if necessary. RESULTS: Of 37 patients with thyroglossal cyst, the block was sufficient in 36 patients, and one patient required ketamine. Block was adequate in 23 of 24 patients with thyroglossal fistula, and one patient required ketamine. Among the branchial cyst and branchial fistula cases, six of 16 patients required ketamine supplementation. Of three thyroidectomy patients, one required ketamine supplementation, and one was converted to conventional general anesthesia. For lymph node excision and lymph node biopsy patients, LA block was sufficient in all 31 cases. In the last group, one of 25 patients required ketamine supplementation. CONCLUSION: The overall success of bilateral cervical plexus block as a sole method of anesthesia in these selected neck surgeries was 91.9% and with low-dose ketamine supplementation it approached more than 99%. However, cervical plexus block was not a good method of anesthesia for thyroid surgery in this study. For the remainder of cases, bilateral cervical plexus block alone or in conjunction with ketamine appeared to be a cheap, safe, and effective alternative to conventional general anesthesia.
