Abstract
Bevacizumab is a monoclonalantibody used as a targeted therapy in blocking vascularendothelial growth factor in different types of oncologicaland non-oncological diseases. It has demonstratedsurvival benefits in the treatment of many types of malignanttumors, including lung cancer. As all drugs have adverseeffects, one of the most uncommon being gastrointestinalperforation and few cases of ureteral stenosis. However,they do not mention or describe the perforation of segmentsof the urinary tract. OBJECTIVE: To describe renal pelvic perforation as an adverseeffect to the use of Bevacizumab. CASE DESCRIPTION: 67-year-old male patient with metastaticlung cancer being treated with Bevacizumab whohas perforation of the renal pelvis is presented. A pyelogramwas performed showing contrast extravasation at theleft renal pelvis and a double J catheter was placed, witha satisfactory clinical course, and tomographic control at 1month without evidence of extravasation of contrast, withdrawingdouble catheter J. CONCLUSION: Renal pelvic perforation secondary toBevacizumab is infrequent, but it must be taken into accountin patients treated with this drug.

Toxicities associated with chemotherapy regimens containing a fluoropyrimidine: A real-life evaluation in France. Eur J Cancer 2020; 124:37-46. [PMID: 31715555 DOI: 10.1016/j.ejca.2019.09.028] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Revised: 09/27/2019] [Accepted: 09/30/2019] [Indexed: 12/14/2022]
Abstract
AIMS Despite fluoropyrimidines (FPs) constituting the main component of the chemotherapy combination protocols in 50% of chemotherapies for solid tumour treatments, incidence data for FP-related toxicity are poorly documented in real life. This study evaluated the number of patients receiving FP-based chemotherapies in France, along with the true incidence of FP-related serious adverse effects (SAEs) before the recent mandatory dihydropyrimidine dehydrogenase (DPD)-screening was introduced by French health authorities, DPD being the rate-limiting enzyme of 5-fluorouracil (5-FU) catabolism. METHODS Exhaustive data on the number of patients treated with FP-based chemotherapy in 2013-2014 were collected in the Centre-Val de Loire region of France. True incidence of SAEs was extracted from a cohort of 513 patients with incident solid tumours receiving first-line FP-based chemotherapy. RESULTS After extrapolation at national level, we estimated that 76,200 patients are currently treated annually with 5FU (53,100 patients, 62% digestive system-related versus 26% breast cancers versus 12% head and neck cancers) or capecitabine (23,100 patients, 45% digestive system-related versus 37% breast cancers versus 18% non-documented). Earlier (in the first two cycles) the SAE incidence rate was 19.3% (95% confidence interval (CI) 16-23%) including one toxic death (0.2%, 95%CI 0-1%). SAE incidence rate was 32.2% (95%CI 28-36%) over the first 6 months of treatment. Incidence of death, life-threatening prognosis or incapacity/disability was 1.4% (95%CI 0.4-2.4%) and 1.6% (95%CI 0.5-2.6%) during first two cycles and first 6 months, respectively. CONCLUSION These data highlight the significant public health issue related to FP toxicity, with around 1200 patients developing FP-related life-threatening prognosis or incapacity/disability annually in France, including 150 toxic deaths. It is hoped that DPD-deficiency screening will reduce such iatrogenic events and eradicate toxic deaths.

Abstract
OBJECTIVES: The present study aimed to determine the pattern of prescription of antiepileptic drugs (AEDs) in a cohort of patients with epilepsy (PWE) attending a tertiary care center of North India. MATERIALS AND METHODS: Demographic variables including age, gender, age at onset, type and frequency of seizures, and prescription of all AEDs (dose and duration) were noted. Descriptive analysis of the use of AEDs was done, and their different combinations were studied. RESULTS: A total of 1187 prescriptions were evaluated. Demography showed 65.7% of males; mean age of 21.9 years (range: 2–77 years), generalized seizures (53%), and focal seizures (47%). Only 21.8% of the patients were seizure free with no seizure in 1 year of treatment. The five most frequently prescribed AEDs out of 12 AEDs were sodium valproate (VPA) (49.6%), clobazam (CLB) (39.3%), levetiracetam (LEV) (28.4%), carbamazepine (CBZ) (27.3%), and phenytoin (PHT) (26.5%). Monotherapy was effective in 36.6% of the patients. Sodium VPA (39.4%), PHT (25.6%), and CBZ (20.1%) were commonly used as monotherapy. Polytherapy was required in 63.4% of the patients, and most commonly prescribed combinations were PHT + CLB (n = 53), sodium VPA + CLB (n = 62), CBZ + CLB (n = 45), PHT + sodium VPA + CLB (n = 28), and CBZ + sodium VPA + CLB (n = 31). CONCLUSIONS: Polytherapy is a very common practice in our tertiary care center. Sodium VPA, a highly prescribed AED, results in good control of generalized seizures, whereas focal seizures are well controlled by CBZ alone as well as in combination. The present study highlights the commonly prescribed combinations of AEDs resulting in control of different types of seizures.

Abstract
PURPOSE Chemotherapy-induced diarrhoea (CID) is a common, but often underreported problem in patients with breast cancer that has a profound effect on quality of life. It is best measured from a patient's perspective, but tools are limited. The aim of this study was to develop and evaluate the Diarrhoea Management Diary (DMD), a self-report measure to assess CID, use of self-management strategies and treatment adherence. METHODS The DMD was constructed using an iterative process of instrument development: concept elicitation (literature review), item generation and reduction (cognitive debriefing), and pilot testing in the target population. After translation into eight languages, the DMD was used in an international randomised trial for women receiving lapatinib and capecitabine for metastatic breast cancer with or without prophylactic octreotide. Patterns of missing data and sensitivity to change were examined. RESULTS The understandability and completeness of the 8-item DMD was confirmed in cognitive interviews and pilot testing. Practicability of the DMD was evaluated in 62 women with metastatic breast cancer (median age 57). Up to 68% reported CID at any given time-point, and 19% had diarrhoea at each time-point. Patients also described efficacy of different strategies for diarrhoea management. Missing data were associated with study discontinuation. DMD missing item response was 0.9%. Sensitivity to change was good at most assessment points. CONCLUSIONS Although further psychometric testing is recommended, initial evaluation of the DMD showed good content validity and practicability in international research with cancer patients.

Abstract
Treatment options for women with recurrent ovarian cancer who have received two or more prior lines of chemotherapy have recently expanded with the U.S. Food and Drug Administration (FDA) and European Commission (EC) approvals of the poly(ADP-ribose) polymerase (PARP) inhibitor rucaparib. As more oncologists begin to use rucaparib and other PARP inhibitors as part of routine clinical practice, awareness of possible side effects and how to adequately manage toxicities is crucial. In this review, we summarize the safety and tolerability of rucaparib reported in an integrated safety analysis that supported the FDA's initial approval of rucaparib in the treatment setting. Additionally, drawing on clinical data and our personal experience with rucaparib, we provide our recommendations on the management of common side effects observed with rucaparib, including anemia, blood creatinine elevations, alanine aminotransferase and aspartate aminotransferase elevations, thrombocytopenia, gastrointestinal-related events (e.g., nausea, vomiting), and asthenia and fatigue. These side effects, many of which appear to be class effects of PARP inhibitors, are often self-limiting and can be managed with adequate interventions such as treatment interruption and/or dose reduction and the use of supportive therapies. Supportive therapies may include blood transfusions for patients with anemia, prophylactic medications to prevent nausea and vomiting, or behavioral interventions to mitigate fatigue. Understanding and appropriate management of potential side effects associated with rucaparib may allow patients with ovarian cancer to continue to benefit from rucaparib treatment. IMPLICATIONS FOR PRACTICE: Rucaparib was recently approved in the U.S. and European Union for use as treatment or maintenance for recurrent ovarian cancer. This review focuses on the safety and tolerability of rucaparib in the treatment setting. Similar side effects are observed in the maintenance setting. Drawing on the authors' clinical experience with rucaparib, rucaparib prescribing information, and published supportive cancer care guidelines, this review discusses how to optimally manage common rucaparib-associated side effects in patients with advanced ovarian cancer in the real-world oncology setting. Adequate management of such side effects is crucial for allowing patients with ovarian cancer to remain on treatment to receive optimal efficacy benefit.

Abstract
INTRODUCTION Patient safety is a pillar of quality health care. Nursing students may commit errors during clinical practice, compromising patient safety. OBJECTIVE Analyze the adverse events, as well as the factors associated with the errors, reported by students from a private university in Santiago, Chile during nursing clinical rotations. METHODS Quantitative cross-sectional descriptive study. A total of 68 errors by first- through fifth-year nursing students were reported between 2012 and 2018. The data collection instrument was the Adverse Events Notification Form from the School of Nursing. This form documented information about the study as well as about the event. RESULTS After this reporting system was established in 2012, the number of events reported increased steadily each year. The greatest numbers of reported errors were committed by fifth-year students (73.5%), and the most common type of error was associated with medication administration (94.2%), including incorrect dose (27.9%) and incorrect medication (17.6%). The major factors contributing to errors were failure to review the "10 rights of medication administration" (85.3%) or lack of critical judgment (7.4%). Most of the errors occurred in public institutions (72.1%). CONCLUSION The results suggest that it would be beneficial to re-evaluate how safety and quality of care are taught at the school of nursing, with an emphasis on understanding the learning styles of students and teaching strategies of instructors. It is crucial that the academic institution remain actively involved in teaching safety-related skills to future nursing professionals. Furthermore, we suggest modifications to the adverse events reporting system that would avoid the need for personal interpretations of the event by the student.

Abstract
Introduction: Peroxisome proliferator-activated receptors (PPARs), PPARα, PPARδ, and PPARγ, play an important role in the regulation of various physiological processes, specifically lipid and energy metabolism and immunity. PPARα agonists (fibrates) and PPARγ agonists (thiazolidinediones) are used for the treatment of hypertriglyceridemia and type 2 diabetes, respectively. PPARδ activation enhances mitochondrial and energy metabolism but PPARδ-acting drugs are not yet available. Many synthetic ligands for PPARs have been developed to expand their therapeutic applications.Areas covered: The authors searched recent patent activity regarding PPAR ligands. Novel PPARα agonists, PPARδ agonists, PPARγ agonists, PPARα/γ dual agonists, and PPARγ antagonists have been claimed for the treatment of metabolic disease and inflammatory disease. Methods for the combination of PPAR ligands with other drugs and expanded application of PPAR agonists for bone and neurological disease have been also claimed.Expert opinion: Novel PPAR ligands and the combination of PPAR ligands with other drugs have been claimed for the treatment of mitochondrial disease, inflammatory/autoimmune disease, neurological disease, and cancer in addition to metabolic diseases including dyslipidemia and type 2 diabetes. Selective therapeutic actions of PPAR ligands should be exploited to avoid adverse effects. More basic studies are needed to elucidate the molecular mechanisms of selective actions.

Abstract
BACKGROUND Research on the major risk statement in direct-to-consumer (DTC) prescription drug television ads has shown that risk severity and actionability can affect consumers' risk comprehension and perceptions. A framing statement presented just before the major risk statement may serve as a cue that directs attention to the risk statement that follows, or it may guide consumers' interpretation of the severity of the risks that follow. OBJECTIVE Examine how the use of different framing statements (severe, life-threatening; serious; or basic) that precede the major risk statement in DTC television ads affect consumers' risk perceptions, risk recognition, benefit perceptions, interest in the drug, and other relevant outcomes. METHODS An online experiment was conducted using a 1 × 3 between-subjects design to compare three different framing statements, which was replicated across three different DTC television ads that focused on different medical conditions (arthritis, lung cancer, and type 2 diabetes). A sample of US adults (N = 1961) was randomly assigned to view one of nine television ads and asked to respond to a questionnaire. RESULTS The type of framing statement had significant effects on perceived risk severity, perceived utility of risk and benefit information, fear of risks, and perceived likelihood of explicit and implicit benefits. CONCLUSIONS Consumers pay attention to and use cues to process and interpret the risk information presented to them in DTC television ads. Using lead-in language that describes risk severity, particularly for products with severe, life-threatening risks, may better allow consumers to make evaluative judgments on risk severity in DTC ads than stating the drug can cause serious reactions or simply that reactions are possible. More work is needed to examine the factors that affect people's understanding of the nature of risk severity, particularly with regard to risk recognition.

Abstract
Frailty syndrome is prevalent among hospitalized older adults as are the occurrence of adverse outcomes. This systematic review and meta-analysis investigated whether frailty in older adults at hospital admission predicts adverse outcomes. Manual (ProQuest, conferences annals and references) and electronic searches (PUBMED, EMBASE, Web of Science, Lilacs, CINAHL, PsycINFO and Google Scholar) were performed. We included prospective studies of hospitalized older adults. Primary outcomes were functional decline at hospital discharge and mortality after discharge. Other data were considered secondary outcomes. Methodological quality was evaluated by the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Twenty-eight papers were included, corresponding to 19 cohorts (5 cohorts for functional decline and 16 for mortality), with moderate to good methodological quality. Being frail [RR: 1.32 (95%CI: 1.04; 1.67)] and pre-frail [RR: 1.51 (95%CI: 1.05; 2.17)] are risk factors for functional decline compared with being nonfrail. Frail individuals had a relative risk for in-hospital mortality and mortality in medium- and long-term compared to nonfrail (in-hospital RR: 8.20, medium RR: 9.49 and long RR: 7.94) and pre-frail (in-hospital RR: 3.19, medium RR: 3.31 and long RR: 3.72). The overall mortality risk in frail individuals is 3.49 and 2.14 times compared to nonfrail and pre-frail, respectively. Length of hospital stay was higher for frail older adults (13.5 days) compared with pre-frail (10.5 days) and nonfrail (8.3 days). Therefore, being frail at hospital admission is a risk factor for in-hospital mortality, long hospital stay, functional decline at hospital discharge, and mortality in the medium- and long-term.

Abstract
Background The risk factors, incidence, and clinical management of pulmonary cement embolism and neurological deficit during percutaneous vertebroplasty (PVP) were evaluated. Methods Three thousand one hundred and seventy-five patients with symptomatic osteoporotic vertebral compression fractures (OVCFs) treated with PVP were retrospectively reviewed in a single institution. Clinical parameters such as age, gender, number of fractures, and time from fracture to vertebroplasty were recorded at the time of surgery. Image and surgical parameters including the amount of cement, the vertebral level, uni- or bipedicle surgical approach, and leakage pattern were recorded. Results Type-C leakage, including paraspinal (25%), intradiscal (26%), and posterior (0.7%) leakage, was more common than type-B (11.4%) and type-S leaks (4.9%). Cement leakage into the spinal canal (type-C posterior) occurred in 26 patients (0.7%), and four patients needed surgical decompression. Three in nine patients with leakage into thoracic spine needed decompressive surgery, but only one of 17 patients into lumbar spine needed surgery (p < 0.01). Age, gender, number of fractures, and time from fracture to vertebroplasty were not risk factors of pulmonary cement embolism or neurological deficit. The risk factor of pulmonary cement embolism was higher volume of PMMA injected (p < 0.001) and risk factor of neurological deficit was type-C posterior cement leakage into thoracic spine. The incidence of pulmonary cement embolism was significantly high in the volume of PMMA injected (PMMA injection < 3.5 cc: 0%; 3.5–7.0 cc: 0.11%; > 7.0 cc: 0.9%; p < 0.01) which needed postoperative oxygen support. Conclusions Cement leakage is relatively common but mostly of no clinical significance. Percutaneous vertebroplasty in thoracic spine and high amount of PMMA injected should be treated with caution in clinical practice.

Abstract
OBJECTIVES The aim of this study was to evaluate the French use, misuse and abuse/dependence of non-injectable forms of fentanyl (transdermal and transmucosal fentanyl formulations). METHODS Problematic use of transdermal and transmucosal fentanyl formulations was evaluated using an approach combining multiple sources of information: (1) spontaneous notifications recorded during 6 years (2010-2015) for transdermal fentanyl form and 3 years for transmucosal fentanyl forms and (2) data from annual epidemiological systematic surveys conducted by the French Addictovigilance Network during 6 years (2010-2015). RESULTS In all, 147 cases were notified for transdermal fentanyl formulation and 109 cases for transmucosal fentanyl formulations. According to the galenic formulation, analysis of these cases emphasizes different profiles: for transdermal fentanyl formulation, two consumption profiles: 1/mainly for analgesic effects (74 %): women (61 %), 47 years, with addictive and/or psychiatric history (46 %), treated for chronic non-cancer related pain (93 %), 2/seeking positive psychic effects other than analgesia (26 %): men (82 %), 32 years, with addictive and/or psychiatric history (87 %) and having obtained the fentanyl patch illegally (60 %) for non-medical use. For transmucosal fentanyl formulations, only one consumption profile was observed: women (52 %), 48 years, with addictive (24 %) and/or psychiatric history (28 %), off label indication (72 %) (indications for non-cancer pain and/or no or insufficient opioid background treatment). The misuse of transmucosal fentanyl formulations implies a high risk of adverse effects: those already known of opioid-based drugs, sometimes lethal (withdrawal syndrome, respiratory and central nervous system depression…) but also serious reactions at the application site (buccal or nasal). For the transdermal fentanyl formulation, 27 cases (18 %) of involuntary intoxication were observed, of which 25 were serious. Nineteen deaths involving both forms of fentanyl have been reported (2 for the transmucosal formulations and 17 for the transdermal formulation). CONCLUSION Our results report significant and worrying misuse of transmucosal fentanyl formulations with wide off-label use and also primary dependence on fentanyl, regardless of galenic formulation, in patients treated for chronic non cancer pain. Given the significant risks of fentanyl, it is necessary to continue the monitoring of misuse, in particular, thanks to the activities of the French Addictovigilance network allowing a multisource approach and who provides information concerning cases of abuse, misuse and dependence.

Abstract
BACKGROUND Caffeine containing energy drinks (EDs) are heavily consumed, particularly among young adults. The number of reports of caffeine intoxication from caffeinated EDs and problems related to caffeine dependence and withdrawal is increasing. The objective was to assess the knowledge and perceived beneficial effects of EDs consumers, to assess consumption patterns and determine the adverse effects experienced by different EDs consumer groups residing in Saudi Arabia. METHODS An observational cross-sectional study with data from a randomly selected Saudi population was conducted during the period of January 15th, 2015, to April 15th, 2015, using a pre-tested 43-item questionnaire. The data were obtained and collected using interview questionnaires. Sociodemographic characteristics and data on EDs consumption patterns, the level of awareness among study subjects, and the purported benefits and reported adverse effects of EDs were collected. Frequency, percentage, and arithmetic means were calculated using Chi-square and ANOVA tests, and data with p < 0.05 were considered significant. RESULTS Of the 816 individuals invited to participate in the study, 783 participants responded and completed interviews, response rate was 96%. Consumers attributed the popularity of EDs to massive advertising media (46.7%) and their stimulating and invigorating effects (37.5%). EDs are consumed by subjects for their effects on fatigue reduction (64.6%), increased alertness and focus (75.8%), and assistance during long driving trips (75.7%). Study subjects reported suffering from adverse effects, including mainly diuresis (53.7%), palpitations (50.7%), insomnia (50.7%). Importantly, an inverse association was identified between knowledge of EDs and consumption rate, and a proportional association was identified between experienced adverse effects and consumption frequency. Lower knowledge scores were identified in daily consumers than in 1-3 times monthly consumers; higher adverse events were experienced by daily consumers than by 1-3 times monthly consumers. The majority of consumers (84.6%) recommended that authorities should regulate EDs consumption. CONCLUSIONS Excessive EDs consumption is associated with an increased risk of experiencing several adverse events, which is commensurate with published studies. Increasing knowledge about EDs and their possible risks could decrease their consumption by the general public.

Abstract
Palbociclib, in conjunction with endocrine therapy, has been approved for the treatment of patients with advanced breast cancer. The common hematological toxicities associated with palbociclib are leukopenia and neutropenia. However, hematological malignancies have not been reported for palbociclib treatment. Here, for the first time, we present a case of acute lymphoblastic leukemia that was diagnosed in a patient undergoing treatment with letrozole and palbociclib for metastatic breast cancer. This case emphasizes the need for long term follow up of patients treated with palbociclib.

Safety and effectiveness of regorafenib in patients with metastatic colorectal cancer in routine clinical practice in the prospective, observational CORRELATE study. Eur J Cancer 2019; 123:146-154. [PMID: 31698328 DOI: 10.1016/j.ejca.2019.09.015] [Citation(s) in RCA: 38] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2019] [Revised: 09/10/2019] [Accepted: 09/12/2019] [Indexed: 01/09/2023]
Abstract
BACKGROUND Regorafenib prolonged overall survival (OS) versus placebo in patients with treatment-refractory metastatic colorectal cancer (mCRC) in phase III trials. We conducted an observational study of regorafenib for patients with mCRC in real-world clinical practice. METHODS The international, prospective, CORRELATE study recruited patients with mCRC previously treated with approved therapies, for whom the decision to treat with regorafenib was made by the treating physician according to the local health authority approved label. The primary objective was safety, assessed by treatment-emergent adverse events (TEAEs; National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.03). RESULTS A total of 1037 patients were treated. The median age was 65 years (range: 24-93); 87% of patients had Eastern Cooperative Oncology Group performance status 0-1, 56% of patients had KRAS, 7% had NRAS and 4% had BRAF mutations. The initial regorafenib dose was 160 mg/day in 57% of patients. The most common grade III or IV drug-related TEAEs were fatigue (9%), hand-foot skin reaction (7%) and hypertension (6%). Drug-related grade V (fatal) TEAEs occurred in 1% of patients. Dose reductions for drug-related TEAEs occurred in 24% of patients. Median OS was 7.7 months (95% confidence interval [CI]: 7.2-8.3), and median progression-free survival (PFS) was 2.9 months (95% CI: 2.8-3.0). CONCLUSIONS In this real-world, observational study of patients with mCRC, the regorafenib toxicity profile was similar to that reported in phase III trials. The starting dose for almost half of patients was less than the approved 160-mg dose, and the median OS and PFS were in the range observed in phase III trials. TRIAL REGISTRATION NCT02042144.

Abstract
INTRODUCTION Methotrexate (MTX) is the drug of choice for juvenile idiopathic arthritis. Its clinical efficacy is limited due to the development of adverse effects (AEs). PATIENTS AND METHODS A retrospective observational study was conducted on the AEs associated with MTX therapy in children diagnosed with juvenile idiopathic arthritis followed-up in a tertiary hospital between 2008 and 2016. RESULTS The study included a total of 107 patients, of whom 71 (66.3%) were girls (66.3%). The median age at diagnosis was 6.4 years (IQR 3.1-12.4), with a median follow-up of 45.7 months (IQR 28.8-92.4). There were 48 patients (44.9%) with oligoarthritis, and 26 children (24.3%) with rheumatoid-factor negative polyarthritis. Of these, 52/107 (48.6%) developed AEs, with the most frequent being gastrointestinal symptoms (35.6%) and behavioural problems (35.6%). An age older than 6 years at the beginning of therapy increased the risk of developing AEs, both in the univariate (OR=3.5; 95% CI: 1.5-7.3) and multivariate (12% increase per year) analyses. The doses used, administration route, or International League of Associations for Rheumatology (ILAR) classification, were not associated with the development of AEs. Twenty children required a dosage or route of administration modification, which resolved the AE in 11 (55%) cases. MTX was interrupted due to the development of AEs in 37/107 patients (34.6%), mainly due to increased plasma transaminases (n=14, 37.8%), gastrointestinal symptoms (n=9, 24.3%) and behavioural problems (n=6, 16.3%). CONCLUSIONS MTX is the therapy of choice for patients with juvenile idiopathic arthritis, but 50% of the children develop some form of AE. Although the AEs are not severe, they lead to interruption of therapy in 35% of the children.

Abstract
BACKGROUND Malta has an average of 3-4 private community pharmacies per locality, providing patients with easy access to medicines yet according to general statistics gathered from European organisations, Internet is used to purchase various online products with medicines being amongst them. OBJECTIVES To identify patterns around internet purchasing of medicines among Maltese residents. METHODS The study followed a mixed methods approach, employing a cross-sectional survey followed by semi-structured interviews. A random sample of 1996 residents were selected from the Maltese electoral register to participate in a postal questionnaire designed to gather data about purchasing prescription-only-medicines (POM) as well as over-the-counter (OTC) medicines. Results were analysed using descriptive statistics and Chi-square to establish associations between responses. Five interviews investigated participants' concerns related to sourcing of medicines. The participants were purposively chosen from the questionnaire respondents. Data were analysed using thematic analysis. RESULTS The survey had a 22% response rate (N = 444) (60% female; mean age 52 years ± 17). Two (0.45%) participants reported purchasing POMs online in the past, while 4.3% (n = 19) purchased OTCs including vitamins, supplements and herbal combinations. The main reasons for OTC online purchasing were lack of local availability (n = 6; 1.4%) and lower price (n = 11; 2.5%). A total of 89% (n = 395) of respondents provided a reason for not purchasing online, with safety issues being the primary reason for 41% (n = 181) of these. Interviewees expressed disregard towards internet purchasing of medicines that was evident from the themes that emerged: definition of 'medicines', health autonomy and trust in self-care, relationships and trust in health professional, restrictions of medicine supply, influence of cost, need for options. CONCLUSIONS The Maltese appear to be rather cautious and do not purchase POMs online, citing the risks that may be associated with internet purchasing. With regards to OTCs, a small percentage purchase these online and exposing them to risks associated with unauthorised sites.

Abstract
Immune checkpoint inhibitors (ICIs) have revolutionized anticancer therapy due to their long-term clinical benefits and immune boosting mechanisms. However, despite their consistent therapeutic effects, the use of ICIs is associated with a spectrum of adverse events due to their autoimmune and auto-inflammatory actions. These adverse events can affect any organ system, including the endocrine, neurologic, gastrointestinal, cardiac, skin, pulmonary, and musculoskeletal systems. Of the immune-related adverse events (irAEs), rheumatic complications are common and appear to be distinct from irAEs in other organs in terms of variability of onset time, capacity for persistence, and relationship with pre-existing autoimmune rheumatologic diseases. In this article, we review the mechanisms of the anti-cancer effects of ICIs, the irAEs of immuno-oncology drugs, and the general recommendations for managing irAEs. In particular, we focus on rheumatologic irAEs and discuss their prevalence, clinical characteristics, and management.

Abstract
Objective: Acute myeloid leukemia (AML) is experiencing a therapeutic renaissance due to the heightened biomedical understanding of AML and patient-focused drug development (PFDD). Many AML patients now live long-term with the side effects of treatment. This study documents the prevalence and severity of AML treatment-related side effects. Methods: A national cross-sectional survey designed with the Leukemia & Lymphoma Society assessed patients' experiences with short-term (nausea/vomiting, diarrhea, hair loss, mouth sores, infection, rash) and long-term (organ dysfunction, chemobrain, fatigue, neuropathy) treatment side effects. Patient and caregiver participants rated side effect severity (none-severe). Results: Survey participants (n = 1182) were mostly female (65%), AML patients (76%), and had undergone chemotherapy (94%). Eighty-seven per cent of participants reported severe short-term effects, and 33% reported severe long-term effects of treatment. Only 11% of respondents did not have any severe effects. Hair loss and fatigue were the most common severe short- and long-term side effects (78%, 33%). There was a moderate correlation between having short- and long-term adverse effects (r = 0.41, p < 0.001). Caregivers were more likely than patients to report severe organ dysfunction, fatigue, and neuropathy (p-values < 0.05). Conclusions: Survivors experience a high burden of side effects from AML treatments highlighting the need for the development of less toxic therapies. Differences in patients' and caregivers' experiences illustrate the importance of sampling from diverse sources to understand the full burden of AML treatment, and the need for less toxic drugs. This study informs patients, patient-advocacy groups, clinicians, and regulators about AML treatment burdens and provides the community with information to inform PFDD.

Abstract
Objective: To investigate the current dosing regimens of gabapentinoids in Pakistani patients with neuropathic pain and to compare their clinical efficacy and tolerability in terms of pain relief and adverse effects using difference in pain score as a treatment outcome. Methods: This observational, prospective study was conducted in 320 patients with neuropathic pain from August 2016 to March 2018 at Basic Medical Sciences Institute (BMSI), Karachi in collaboration with Shifa International Hospital and Benazir Bhutto Hospital, Islamabad. Demographic data, treatment-related adverse effects and pain intensity was documented at recruitment and follow up visits at two, four and eight weeks. Discontinuation due to adverse effects and lack of efficacy were also recorded. Data was entered and analyzed using SPSS version 22. Results: Mean age of patients was 52.57±12.47 and the most common ethnicity were Punjabi speaking population (66%). Diabetic neuropathy (51%) was the most common etiology followed by radicular pain (25%). Mean dosages of pregabalin and gabapentin were 114mg and 470mg respectively. Mean pain score was significantly reduced by gabapentinoids (<0.001). Dizziness, drowsiness and somnolence were frequent adverse effects. Common dosages for pregabalin and gabapentin were 75 mg/day and 300 mg/day respectively. Conclusion: Current dosing regimens of gabapentinoids in Pakistani patients with neuropathic pain were found to be efficacious at low dosages in comparison to international recommended dosages. Gabapentin and pregabalin were both similar in terms of reducing pain score but onset of pain relief was relatively faster with pregabalin. Dizziness, drowsiness and somnolence were frequently reported with both gabapentinoids; however, visual blurring, ataxia and weight gain were observed only with the use of pregabalin. Adverse effects are frequently observed with gabapentinoids which necessitates reverting back to low dosages or switching to other drugs for pain relief.

Abstract
BACKGROUND Non-traumatic intramural hematomas of the small bowel (IHSB) are rare conditions which occur due to anticoagulant therapy. In this study, we aimed to explain our clinical approach to non-traumatic IHSB due to anticoagulant overdose and to present the long-term outcomes of the cases who were hospitalized. METHODS Sixteen patients with non-traumatic IHSB were included and their medical records were retrospectively reviewed. RESULTS Our patients included ten women and six men, with a mean age of 77.5 ± 8.4 (range: 65-95) years. All patients had been using oral anticoagulants (OACs) due to various cardiovascular and cerebral comorbidities. Common complaints at the time of admission included abdominal pain, vomiting and weakness. Ten patients (62%) had anemia, fifteen (94%) had leukocytosis and all patients (100%) had high levels of C-reactive protein (CRP). Abdominal computed tomography (CT) established the final diagnosis of IHSB in all patients. Fourteen patients (87%) were followed up with conservative therapy. Since the clinical course did not improve in two patients (12%), surgery was mandated. The mean duration of hospitalization was 10.25 ± 3.6 days (range: 3-17 days). Mortality occurred in two patients (12%). CONCLUSION IHSB should be considered in patients presenting with abdominal complaints and increased levels on coagulation tests. The diagnosis should be confirmed by abdominal CT scan, if possible. Accurate and timely diagnosis allows patients to be successfully treated without need for surgery.
