A systematic review assessing the under-representation of elderly adults in COVID-19 trials
Coronavirus disease (COVID-19) has caused a pandemic threatening millions of people worldwide. Yet studies specifically assessing the geriatric population are scarce. We aimed to examine the participation of elderly patients in therapeutic or prophylactic trials on COVID-19
SGLT-2 Inhibitors: A Novel Mechanism in Targeting Glycemic Control in Type 2 Diabetes Mellitus
OBJECTIVE: To review the chemistry, pharmacology, pharmacodynamics, pharmacokinetics, clinical efficacy, tolerability, dosing, drug interactions, and administration of canagliflozin, dapagliflozin, and empagliflozin, and comparing the benefit and risk aspects of using these agents in the older adult diabetes patient population.
DATA SOURCES, STUDY SELECTION, DATA EXTRACTION, AND DATA SYNTHESIS: A search of PubMed using the terms SGLT-2 inhibitors, canagliflozin, dapagliflozin, empagliflozin, efficacy, and tolerability was performed to find relevant primary literature on each of the sodium/glucose cotransporter 2 (SGLT-2) inhibitors currently approved for use in type 2 diabetes. Phase III trials for all agents were included. All English-language articles from 2010 to 2015 appearing in these searches were reviewed for relevance to this paper. In addition, related articles suggested in the PubMed search were also reviewed. The SGLT-2 inhibitors have shown a reduction in hemoglobin A1c values and fasting plasma glucose levels with a low incidence of hypoglycemia. The incidence of mycotic infections is increased in patients taking an SGLT-2 inhibitor.
CONCLUSION: SGLT-2 inhibitors may be a viable treatment option for patients not controlled on other oral agents. The risk of hypoglycemia is small. However, the clinical efficacy and tolerability of these agents has not been fully elucidated in older and frail patients
The frequency of epileptic seizures during therapy with antipsychotics and placebo within randomized-controlled trials
Die vorliegende Arbeit untersucht die AuftretenshĂ€ufigkeit epileptischer AnfĂ€lle als schwere unerwĂŒnschte Wirkung (âserious adverse eventsâ) wĂ€hrend der Therapie mit Antipsychotika der zweiten Generation im Rahmen randomisierter placebo-kontrollierter Studien. Anhand vordefinierter Ein- und Ausschlusskriterien wurden verschiedene Literaturdatenbanken systematisch nach Medikamentenstudien durchsucht. In der Auswertung wurden die HĂ€ufigkeiten in der Gesamtgruppe sowie in verschiedenen Subgruppen bestimmt sowie metaanalytisch verglichen. Es wurden 314 Studien mit 67.642 Patienten eingeschlossen. Insgesamt zeigte sich kein Hinweis auf ein erhöhtes Krampfanfallrisiko unter Antipsychotika im Vergleich zu Placebo.This doctoral thesis is investigating the frequency of epileptic seizures described as serious adverse events during therapy with second-generation antipsychotics in placebo-controlled randomized trials. There was a systematic search in different databases for trials according to predefined in- and exclusion criteria. The frequencies of the total population and of various subgroups were determined and meta-analytically compared. 314 Studies with 67.642 Patients could be included. Altogether there was no evidence for increased seizure risk during therapy with antipsychotics compared to placebo
Design and methodology of the screening for CKD among older patients across Europe (SCOPE) study: a multicenter cohort observational study
Background: Decline of renal function is common in older persons and the prevalence of chronic kidney disease (CKD) is rising with ageing. CKD affects different outcomes relevant to older persons, additionally to morbidity and mortality which makes CKD a relevant health burden in this population. Still, accurate laboratory measurement of kidney function is under debate, since current creatinine-based equations have a certain degree of inaccuracy when used in the older population. The aims of the study are as follows: to assess kidney function in a cohort of 75+ older persons using existing methodologies for CKD screening; to investigate existing and innovative biomarkers of CKD in this cohort, and to align laboratory and biomarker results with medical and functional data obtained from this cohort. The study was registered at ClinicalTrials.gov, identifier NCT02691546, February 25th 2016. Methods/design: An observational, multinational, multicenter, prospective cohort study in community dwelling persons aged 75 years and over, visiting the outpatient clinics of participating institutions. The study will enroll 2450 participants and is carried out in Austria, Germany, Israel, Italy, the Netherlands, Poland and Spain. Participants will undergo clinical and laboratory evaluations at baseline and after 12 and 24 months-follow-up. Clinical evaluation also includes a comprehensive geriatric assessment (CGA). Local laboratory will be used for 'basic' parameters (including serum creatinine and albumin-to-creatinine ratio), whereas biomarker assessment will be conducted centrally. An intermediate telephone follow-up will be carried out at 6 and 18 months. Discussion: Combining the use of CGA and the investigation of novel and existing independent biomarkers within the SCOPE study will help to provide evidence in the development of European guidelines and recommendations in the screening and management of CKD in older people
Interventions for preventing delirium in hospitalised non-ICU patients
BACKGROUND: Delirium is a common mental disorder, which is distressing and has serious adverse outcomes in hospitalised patients. Prevention of delirium is desirable from the perspective of patients and carers, and healthcare providers. It is currently unclear, however, whether interventions for preventing delirium are effective. OBJECTIVES: To assess the effectiveness of interventions for preventing delirium in hospitalised non-Intensive Care Unit (ICU) patients. SEARCH METHODS: We searched ALOIS - the Cochrane Dementia and Cognitive Improvement Group's Specialized Register on 4 December 2015 for all randomised studies on preventing delirium. We also searched MEDLINE (Ovid SP), EMBASE (Ovid SP), PsycINFO (Ovid SP), Central (The Cochrane Library), CINAHL (EBSCOhost), LILACS (BIREME), Web of Science core collection (ISI Web of Science), ClinicalTrials.gov and the WHO meta register of trials, ICTRP. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of single and multi- component non-pharmacological and pharmacological interventions for preventing delirium in hospitalised non-ICU patients. DATA COLLECTION AND ANALYSIS: Two review authors examined titles and abstracts of citations identified by the search for eligibility and extracted data independently, with any disagreements settled by consensus. The primary outcome was incidence of delirium; secondary outcomes included duration and severity of delirium, institutional care at discharge, quality of life and healthcare costs. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes; and between group mean differences and standard deviations for continuous outcomes. MAIN RESULTS: We included 39 trials that recruited 16,082 participants, assessing 22 different interventions or comparisons. Fourteen trials were placebo-controlled, 15 evaluated a delirium prevention intervention against usual care, and 10 compared two different interventions. Thirty-two studies were conducted in patients undergoing surgery, the majority in orthopaedic settings. Seven studies were conducted in general medical or geriatric medicine settings.We found multi-component interventions reduced the incidence of delirium compared to usual care (RR 0.69, 95% CI 0.59 to 0.81; seven studies; 1950 participants; moderate-quality evidence). Effect sizes were similar in medical (RR 0.63, 95% CI 0.43 to 0.92; four studies; 1365 participants) and surgical settings (RR 0.71, 95% CI 0.59 to 0.85; three studies; 585 participants). In the subgroup of patients with pre-existing dementia, the effect of multi-component interventions remains uncertain (RR 0.90, 95% CI 0.59 to 1.36; one study, 50 participants; low-quality evidence).There is no clear evidence that cholinesterase inhibitors are effective in preventing delirium compared to placebo (RR 0.68, 95% CI, 0.17 to 2.62; two studies, 113 participants; very low-quality evidence).Three trials provide no clear evidence of an effect of antipsychotic medications as a group on the incidence of delirium (RR 0.73, 95% CI, 0.33 to 1.59; 916 participants; very low-quality evidence). In a pre-planned subgroup analysis there was no evidence for effectiveness of a typical antipsychotic (haloperidol) (RR 1.05, 95% CI 0.69 to 1.60; two studies; 516 participants, low-quality evidence). However, delirium incidence was lower (RR 0.36, 95% CI 0.24 to 0.52; one study; 400 participants, moderate-quality evidence) for patients treated with an atypical antipsychotic (olanzapine) compared to placebo (moderate-quality evidence).There is no clear evidence that melatonin or melatonin agonists reduce delirium incidence compared to placebo (RR 0.41, 95% CI 0.09 to 1.89; three studies, 529 participants; low-quality evidence).There is moderate-quality evidence that Bispectral Index (BIS)-guided anaesthesia reduces the incidence of delirium compared to BIS-blinded anaesthesia or clinical judgement (RR 0.71, 95% CI 0.60 to 0.85; two studies; 2057 participants).It is not possible to generate robust evidence statements for a range of additional pharmacological and anaesthetic interventions due to small numbers of trials, of variable methodological quality. AUTHORS' CONCLUSIONS: There is strong evidence supporting multi-component interventions to prevent delirium in hospitalised patients. There is no clear evidence that cholinesterase inhibitors, antipsychotic medication or melatonin reduce the incidence of delirium. Using the Bispectral Index to monitor and control depth of anaesthesia reduces the incidence of postoperative delirium. The role of drugs and other anaesthetic techniques to prevent delirium remains uncertain
What's New in Intravenous Anaesthesia?:New Hypnotics, New Models and New Applications
New anaesthetic drugs and new methods to administer anaesthetic drugs are continually becoming available, and the development of new PK-PD models furthers the possibilities of using arget controlled infusion (TCI) for anaesthesia. Additionally, new applications of existing anaesthetic drugs are being investigated. This review describes the current situation of anaesthetic drug development and methods of administration, and what can be expected in the near future
The role of paliperidone extended release for the treatment of bipolar disorder
Jehan Marino1, Clayton English2, Joshua Caballero1, Catherine Harrington11College of Pharmacy, Nova Southeastern University, Fort Lauderdale, FL, 2College of Pharmacy, Albany College of Pharmacy and Health Sciences, Colchester, VT, USABackground: Bipolar disorder (BD) is a chronic, relapsing, episodic mental illness associated with other psychiatric comorbidities. There is a substantial economic burden with BD, which makes it challenging to treat. The aim of this review is to evaluate the pharmacology, clinical efficacy, and safety data related to paliperidone extended release (ER) for the treatment of BD.Methods: A literature search was performed from January 1966 through January 2012 using PreMEDLINE, MEDLINE, EMBASE, IPA, and ClinicalTrials.gov to identify articles in English regarding the pharmacology, clinical efficacy, and safety of paliperidone ER in acute mania or mixed episodes or in the maintenance treatment of BD I.Results: There are currently three published studies relating to the use of paliperidone ER for the treatment of BD. Two of these evaluated paliperidone ER as monotherapy for acute mania, while the other assessed its role as adjunct with a mood stabilizer.Conclusion: According to the limited available evidence, paliperidone at higher doses of ER 9–12 mg/day may be a safe and efficacious treatment option for acute episodes of mania in BD. A once-daily dose formulation may improve patient adherence to treatment; however, the cost of paliperidone ER, which is higher than that of generically available second-generation antipsychotics (such as olanzapine and risperidone), and a lack of alternative dosage forms (ie, liquid, intramuscular) compared with other agents may limit its usefulness in the treatment of BD. The role of paliperidone ER as an adjunctive agent or for long-term use requires further investigation.Keywords: paliperidone ER, bipolar disorder, clinical efficacy, safet
Empagliflozin: an exciting prospect in the treatment of diabetes
Type 2 diabetes mellitus (T2DM) continues to be a chronic and disabling disease that is associated with high mortality and morbidity. The epidemic burden of diabetes mellitus has increased in developing countries and Asia is considered as the âdiabetic epicentreâ. Type 2 diabetes (T2DM), is characterised by reduced secretion of insulin from pancreatic beta cells independently or associated with reduced response of peripheral tissues to circulating insulin. A proper glycaemic control is essential to delay the micro and macrovascular complications of T2DM. Standard anti-diabetic agents including insulin happen to induce minor to major adverse outcomes in certain populations over prolonged period of administration. Hence there has been a compelling need to develop newer and novel approach to treatment of T2DM. Sodium-glucose co-transporter 2 (SGLT-2) inhibitors are a novel category of drugs that happen to reduce glycaemic overload by inducing glycosuria. The safety, efficacy and tolerability profile of these drugs were studied separately under various trials and was approved for use in August 2014 by US-FDA. This review is an attempt to describe the history of SGLT-2 inhibitors, their mechanism of action, safety and efficacy as well as its current status among anti-diabetic agents.Â
