Abstract Drugs are the imperial part of modern society, but along with their therapeutic effects, drugs can also cause adverse effects, which can be mild to morbid. Pharmacovigilance is the process of collection, detection, assessment, monitoring and prevention of adverse drug events in both clinical trials as well as in the post-marketing phase. The recent trends in increasing unknown adverse events, known as signals, have raised the need to develop an ideal system for monitoring and detecting the potential signals timely. The process of signal management comprises of techniques to identify individual case safety reports systematically. Automated signal detection is highly based upon the data mining of the spontaneous reporting system such as reports from health care professional, observational studies, medical literature or from social media. If a signal is not managed properly, it can become an identical risk associated with the drug which can be hazardous for the patient safety and may have fatal outcomes which may impact health care system adversely. Once a signal is detected quantitatively, it can be further processed by the signal management team for the qualitative analysis and further evaluations. The main components of automated signal detection are data extraction, data acquisition, data selection, and data analysis and data evaluation. This system must be developed in the correct format and context, which eventually emphasizes the quality of data collected and leads to the optimal decision-making based upon the scientific evaluation.

BACKGROUND: Statistical techniques have traditionally been underused in spontaneous reporting systems used for postmarketing surveillance of adverse drug events. Regulatory agencies, pharmaceutical companies, and drug monitoring centers have recently devoted considerable efforts to develop and implement computer-assisted automated signal detection methodologies that employ statistical theory to enhance screening efforts of expert clinical reviewers. OBJECTIVE: To provide a concise state-of-the-art review of the most commonly used automated signal detection procedures, including the underlying statistical concepts, performance characteristics, and outstanding limitations, and issues to be resolved. DATA SOURCES: Primary articles were identified by MEDLINE search (1965–December 2002) and through secondary sources. STUDY SELECTION AND DATA EXTRACTION: All of the articles identified from the data sources were evaluated and all information deemed relevant was included in this review. DATA SYNTHESIS: Commonly used methods of automated signal detection are self-contained and involve screening large databases of spontaneous adverse event reports in search of interestingly large disproportionalities or dependencies between significant variables, usually single drug–event pairs, based on an underlying model of statistical independence. The models vary according to the underlying model of statistical independence and whether additional mathematical modeling using Bayesian analysis is applied to the crude measures of disproportionality. There are many potential advantages and disadvantages of these methods, as well as significant unresolved issues related to the application of these techniques, including lack of comprehensive head-to-head comparisons in a single large transnational database, lack of prospective evaluations, and the lack of gold standard of signal detection. CONCLUSIONS: Current methods of automated signal detection are nonclinical and only highlight deviations from independence without explaining whether these deviations are due to a causal linkage or numerous potential confounders. They therefore cannot replace expert clinical reviewers, but can help them to focus attention when confronted with the difficult task of screening huge numbers of drug–event combinations for potential signals. Important questions remain to be answered about the performance characteristics of these methods. Pharmacovigilance professionals should take the time to learn the underlying mathematical concepts in order to critically evaluate accumulating experience pertaining to the relative performance characteristics of these methods that are incompletely defined.

This document provides an overview on identifying ICSR (Individual case safety reports) & Drug Safety Classification of Adverse Drug Events from free Text Electronic Patient Records and Information. As a remarkable rise is observed in the usage of digital health records the potential for extensive clinical data extraction has drawn much attention. We intend to separate the causes and effects of unfriendly drugs from the records. We have therefore promoted a machine learning-based framework for the planned signature test of hostile drugs or safe phrases in the event of a report. In addition, the framework also uses named substance recognition based on word references to identify drugs and diseases that are present at the same time. The framework evaluation of physical comments in the corpus and a context-related analysis of consumption, which was carried out on preselected drugs, showed convincing results.

Objective: To review the efficacy and safety of medications used in the management of steroid-induced psychosis. Data Sources: A comprehensive literature search was conducted using PubMed, MEDLINE, ProQuest, and Scopus between May and October 2020 using the following search terminology: “steroid-induced psychosis” OR “corticosteroid-induced psychosis.” Study Selection and Data Extraction: Definitive cases, as defined by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, were included in this review. Geriatric patients >65 years of age, those with a confounding neurological condition such as a traumatic brain or spinal cord injury, or those with active malignancy were excluded. Data Synthesis: A total of 13 patient cases were included in this review, representing 8 male patients and 5 female patients. The mean age at symptom presentation was 42.5 years. Six patients presented with delusions, 5 presented with hallucinations, and 2 presented with both manifestations; 12 patients were managed with an antipsychotic, with haloperidol being the most commonly prescribed, followed by risperidone. One patient was managed with lithium and clonazepam alone. All patients returned to their psychological baseline upon the discontinuation or decreased dose of steroids in combination with Pharmacological intervention, though the time to resolution of symptoms varied significantly. No notable adverse drug events associated with treatments were reported. Conclusions: Steroid-induced psychosis is a serious adverse effect of corticosteroid therapy; however, management strategies that combine a dose reduction or elimination of steroids, in combination with an antipsychotic medication, are effective in resolving this syndrome.

Objective: To review the pharmacology, pharmacokinetics, efficacy, safety, and place in therapy of bezlotoxumab (BEZ), a novel monoclonal antibody against Clostridium difficile toxin B. Data Sources: A PubMed search was conducted for data between 1946 and April 2017 using MeSH terms bezlotoxumab, MK-6072, or MDX-1388 alone and the terms Clostridium difficile combined with monoclonal antibody or antitoxin. Study Selection and Data Extraction: The literature search was limited to English-language studies that described clinical efficacy, safety, and pharmacokinetics in humans and animals. Abstracts featuring prepublished data were also evaluated for inclusion. Data Synthesis: BEZ is indicated for adult patients receiving standard-of-care (SoC) antibiotics for C difficile infection (CDI) to prevent future recurrence. Two phase III trials—MODIFY I (n = 1452) and MODIFY II (n = 1203)—demonstrated a 40% relative reduction in recurrent CDI (rCDI) with BEZ compared with placebo (16.5% vs 26.6%, P < 0.0001). The most common adverse drug events associated with BEZ were mild to moderate infusion-related reactions (10.3%). Conclusions: In patients treated with SoC antibiotics, BEZ is effective in decreasing rCDI. BEZ has no apparent effect on treatment of an initial CDI episode. In light of increasing rates of CDI, BEZ is a promising option for preventing recurrent episodes. The greatest benefit has been demonstrated in high-risk patients, though the targeted patient population is yet to be defined.

This volume tells the little-known story of the Dominican Family—priests, sisters, brothers, contemplative nuns, and lay people—and integrates it into the history of the United States. Starting after the Civil War, the book takes a thematic approach through twelve essays examining Dominican contributions to the making of the modern United States by exploring parish ministry, preaching, health care, education, social and economic justice, liturgical renewal and the arts, missionary outreach and contemplative prayer, ongoing internal formation and renewal, and models of sanctity. It charts the effects of the United States on Dominican life as well as the Dominican contribution to the larger U.S. history. When the country was engulfed by wave after wave of immigrants and cities experienced unchecked growth, Dominicans provided educational institutions; community, social, and religious centers; and health care and social services. When epidemic disease hit various locales, Dominicans responded with nursing care and spiritual sustenance. As the United States became more complex and social inequities appeared, Dominicans cried out for social and economic justice. Amidst the ugliness and social dislocation of modern society, Dominicans offered beauty through the liturgical arts, the fine arts, music, drama, and film, all designed to enrich the culture. Through it all, the Dominicans cultivated their own identity as well, undergoing regular self-examination and renewal.

Introduction: The World Health Organization creates norms and guidelines for the adoption of good practices in health care that are provided to the surgical patient. In order to prevent and control infections associated with health care, the nurse must follow the guidelines for preparing the surgical patient for success. These infections can be particularly harmful to the elderly person given their vulnerability. The preoperative preparation, includes the trichotomy as one of the interventions to be performed, however, is one of the most controversial interventions that has caused in clinical practice, by the potential risk of infection in the surgical patient. Aim: To investigate the need for trichotomy, or removal of hair, in the preparation of the skin of the surgical patient, clarifying which is the most appropriate technique in the prevention of infection. Methodology: we conducted an umbrella review. The documentary research followed the consultation of bibliographic sources in the Cumulative Index to Nursing & Allied Health (CINAHL) and Public/Publisher Medline (PubMed) databases. The researched articles were grouped in a time horizon between 2011 and 2020. Afer data extraction, a narrative analysis was performed. Results: We found 40 articles from which 8 were selected. Conclusion: Trichotomy should be avoided by increasing the risk of infection of the surgical site. Innovative haircut and vacuum technologies can help in hair removal, mitigating the risk of contaminating the surgical incision. The timing of the trichotomy is not consensual among researchers.
