Abstract:
A prospective observational study was carried out to evaluate the patterns, severity, and management of chemotherapy-induced adverse drug reactions (ADRs) in cancer patients. The study included 135 patients receiving chemotherapy at a tertiary care hospital over six months. ADRs were assessed using Naranjo's causality assessment scale, Hartwig's severity scale, and Schumock and Thornton preventability criteria. The mean age of patients was 49.31 ± 12.69 years, with females (63%) experiencing more ADRs than males (37%). Breast cancer was the most prevalent malignancy (34.8%), followed by ovaria

Abstract:
Background: Cancer chemotherapy involves highly complex regimens using antineoplastic agents like taxanes (paclitaxel, docetaxel) etc. Taxanes cause hypersensitivity reactions (HSRs) like redness, rashes, dyspnoea, severe anaphylaxis and death. In this study, adverse drug reactions (ADRs) associated with taxanes are described & analysed on their severity and preventability. The present study aims to analyse and determine the prevalence of ADRs, especially HSRs in patients treated with taxanes.Methods: After getting IEC approval, the present study is done retrospectively by assessing the HS

Abstract:
Background: The causality assessment system proposed by the WHO collaborating centre for international drug monitoring, the Uppsala monitoring centre (WHO-UMC) and the Naranjo probability scale are the generally accepted and most widely used methods for causality assessment. Both these scales are structured, transparent, consistent, and easy to apply with distinct advantages. The PvPI recommends use of WHO-UMC scale while many clinicians prefer Naranjo scale for its simplicity. As both these scales are used very widely in practise, it is important to study the level of agreement among them, to

Abstract Background: To develop a structured and harmonized causality assessment method has been a holy grail in pharmacovigilance. The Pharmacovigilance Programme of India (PvPI) recommends the use of the World Health Organization-Uppsala Monitoring Centre (WHO-UMC) scale, whereas many clinicians prefer the Naranjo algorithm for its simplicity. There is no universally accepted method for the causality grading of ADRs. In the present study, we assessed agreement and correlation between the two widely used causality assessment scales, that is, the WHO-UMC criteria and the Naranjo algorithm. Mat

 Introduction: Globally, Adverse Drug Reaction (ADR) has been listed as the sixth leading causes of death. Recognition of ADR and establishment of relationship of drug with the symptom is the first step to the management of the problem. In this study, Naranjo algorithm has been used which is one of the most accepted tools for the assessment of causality of ADR with the suspected drug.
 Methods: A retrospective descriptive study was done which included 35 reported cases of ADRs in Drug Information Unit (DIU) in tertiary care teaching institute of Nepal from Dec 2

Abstract:
Aim: Accurate causality assessment (CA) of adverse events (AEs) is important in clinical research and routine clinical practice. The Naranjo scale (NS) used for CA lacks specificity, leading to a high rate of false positive causal associations. NS is a simple scale for CA; however, its limitations have reduced its popularity in favour of other scales. We therefore attempted to improvise the algorithm by addressing specific lacunae in NS. Methods: We attempted to modify the existing NS by (a) changing the weightage given to certain responses, (b) achieving higher resolution to certain responses

Abstract:
ADRs usually do not present with unique clinical and laboratory findings making it difficult to demarcate them from the concurrent illness. For the estimation of the probability that a drug caused an adverse event several methods have been developed namely, the WHO-UMC criteria, the Naranjo probability scale, the Kramer scale and the Karch and Lasagna scale. But none of the available assessment methods have been shown to produce a precise and reliable quantitative estimation of relationship likelihood.

One high-profile example of these discrepancies was related to postmenopausal hormone therapy (HT) use and its effects on cardiovascular disease and cancer. The Women’s Health Initiative (WHI), a National Heart, Lung, and Blood Institute–sponsored program, was designed to test three interventions for the prevention of chronic diseases in postmenopausal women, each of which was moti

Understanding the current fire-climate relationships is of utmost importance in order to assess the potential impacts that projected climate may exert in the near future. However, the many factors involved in fire activity often prevent a proper attribution of the observed variability. Unlike the many previous correlative studies, here we address this problem using a 'causality' measure known as “pseudo transfer entropy” (pTE), relating three widely used fire danger indices to the global observed burned areas (namely the Canadian Fire Weather Index, the Fire Danger Index from the Australia

Abstract Elevation valleys are suspected to play a role in pipeline corrosion. One proposed mechanism is water and solids accumulation at these valley locations, which play a role in combination with other variables such as flowrate and pipe geometry, among others. From our literature review no studies have been published that show the relationship between valley locations and corrosion anomalies using real world inspection data at large scale.

Abstract:
Causality and Predictability of Complex Systems pose fundamental challenges even under well-defined structural stochastic-dynamic conditions where the laws of motion and system symmetries are known. However, the edifice of complexity can be profoundly transformed by structural-functional coevolution and non-recurrent elusive mechanisms changing the very same invariants of motion that had been taken for granted. This leads to recurrence collapse and memory loss, precluding the ability of traditional stochastic-dynamic and information-theoretic metrics to provide reliable information about the n
