Patterns of transfusion burden in an unselected population of patients with myelodysplastic syndromes:A population-based study

BACKGROUND: Ineffective hematopoiesis in patients with myelodysplastic syndromes (MDS) often results in transfusion dependence. The burden of frequent transfusions in the real-world MDS population is largely unknown.STUDY DESIGN AND METHODS: An observational, retrospective, population-based study, using the HemoBase registry, was performed including all patients diagnosed with MDS between 2005 and 2017 in Friesland, a province in the Netherlands with approximately 650,000 inhabitants. Detailed clinical information was collected from the electronic health records. Transfusion burden was classified according to the International Working Group 2018 criteria: not transfusion dependent, low (LTB), or high transfusion burden (HTB). Univariate and multivariable regression analyses were performed.RESULTS: Of 292 patients, 136 (46.6%) had a HTB of ≥8 units/16 weeks and 17 (5.8%) had a LTB of 3-7 units/16 weeks. This was present in all types of MDS patients, but patients aged 75-84 years (odds ratio [OR] 4.02, 95% confidence interval [CI]: 1.84-8.82), high-risk MDS patients (OR 2.88, 95% CI: 1.08-7.68) and MDS-EB-2 patients (OR 7.07, 95% CI: 2.17-22.90) were particularly at risk for a HTB.DISCUSSION: This study provides a reliable estimate of the transfusion burden in real-world MDS patients, with almost half of the patients having a HTB. A HTB was observed in all MDS subtypes and both low- and high-risk MDS. Therefore, we conclude that the entire MDS population might benefit from novel agents that reduce the transfusion need and that might have beneficial effects on patient outcomes and healthcare utilization outcomes.</p

Appropriate choice of drugs in older patients

Older patients use many drugs, while there is hardly any information about the effect and safety of these in elderly patients. It appears that only 56%, and 20% of the information required by the European Medicines Agency (EMA) concerning use of medication in the elderly is stated in the patient information leaflet and in the Dutch Pharmacotherapeutic Compass, respectively. The Expertise Centre PHarmacotherapy in Old Persons (Ephor) gathered all available information about drug prescribing in older patients for a number of drug groups from national and international literature, and provided prescribing advice. This information will be made available to users of the Dutch Pharmacotherapeutic Compass, for quick accessibility.</p

Proton-pump inhibitors are associated with a reduced risk for bleeding and perforated gastroduodenal ulcers attributable to non-steroidal anti-inflammatory drugs: a nested case-control study

Treatment with non-steroidal anti-inflammatory drugs (NSAIDs) is hampered by gastrointestinal ulcer complications, such as ulcer bleeding and perforation. The efficacy of proton-pump inhibitors in the primary prevention of ulcer complications arising from the use of NSAIDs remains unproven. Selective cyclooxygenase-2 (COX-2) inhibitors reduce the risk for ulcer complications, but not completely in high-risk patients. This study determines which patients are especially at risk for NSAID ulcer complications and investigates the effectiveness of different preventive strategies in daily clinical practice. With the use of a nested case-control design, a large cohort of NSAID users was followed for 26 months. Cases were patients with NSAID ulcer complications necessitating hospitalisation; matched controls were selected from the remaining cohort of NSAID users who did not have NSAID ulcer complications. During the observational period, 104 incident cases were identified from a cohort of 51,903 NSAID users with 10,402 patient years of NSAID exposure (incidence 1% per year of NSAID use, age at diagnosis 70.4 ± 16.7 years (mean ± SD), 55.8% women), and 284 matched controls. Cases were characterised by serious, especially cardiovascular, co-morbidity. In-hospital mortality associated with NSAID ulcer complications was 10.6% (incidence 21.2 per 100,000 NSAID users). Concomitant proton-pump inhibitors (but not selective COX-2 inhibitors) were associated with a reduced risk for NSAID ulcer complications (the adjusted odds ratio 0.33; 95% confidence interval 0.17 to 0.67; p = 0.002). Especially at risk for NSAID ulcer complications are elderly patients with cardiovascular co-morbidity. Proton-pump inhibitors are associated with a reduced risk for NSAID ulcer complications

Assessment of Contraceptive Counseling and Contraceptive Use in Women After Bariatric Surgery

BACKGROUND: Reproductive-aged women are, according to American and European guidelines, recommended to avoid pregnancy for 12-24 months after bariatric surgery. Oral contraceptives may have suboptimal efficacy after malabsorptive bariatric procedures. AIM: The aim of this study was to assess contraceptive use pre- and postoperatively in women who underwent bariatric surgery in two obesity clinics in The Netherlands. Also, the recall of contraceptive and pregnancy counseling was investigated. METHODS: A validated questionnaire was performed among women aged 18-45 years who underwent bariatric surgery from October 2017 through August 2018. RESULTS: In total, 230 women were eligible for final analysis. Postoperatively, 60% used safe contraception, 16.1% unsafe contraception, and 23.9% no contraception. In this study, 43.7% of women using a potential unsafe contraceptive method preoperatively switched to a safe method of contraception postoperatively (p < 0.0001). Only 62.6% of women confirmed to have received contraceptive counseling, mainly preoperatively. The odds ratio for receiving contraceptive counseling and using safe contraceptive methods compared with not receiving contraceptive counseling was 2.20 (95% CI, 1.27-3.79; p = 0.005). Eighty-three percent confirmed that they have received counseling regarding delaying a pregnancy, and 52.6% were familiar with the recommendation to avoid a pregnancy for 24 months postoperatively. CONCLUSIONS: In our study, 60% of women are using safe contraception postoperatively. Contraceptive counseling is suboptimal as 62.6% recall receiving counseling. Those who confirmed receiving counseling were more likely to use safe contraception after bariatric surgery. More counseling and monitoring in the postoperative and in the outpatient setting is recommended

Adverse Drug Reactions of Intranasal Corticosteroids in the Netherlands:An Analysis from the Netherlands Pharmacovigilance Center

BACKGROUND: Intranasal corticosteroids are one of the cornerstone treatment options for allergic rhinitis and chronic sinusitis complaints. Safety information in the summary of product characteristics may not be representative for observations in daily clinical practice. The Netherlands Pharmacovigilance Center (Lareb) collects post-marketing safety information, using spontaneous reporting systems. OBJECTIVE: Our objective was to analyse reports of adverse drug reactions associated with intranasal corticosteroids reported in the Dutch spontaneous reporting database of the Netherlands Pharmacovigilance Center Lareb to obtain insight into real-world safety data. METHODS: We retrospectively examined all adverse drug reactions of intranasal corticosteroids reported to the Netherlands Pharmacovigilance Center Lareb, entered into the database from 1991 until 1 July, 2020. RESULTS: In total, 2263 adverse drug reactions after intranasal corticosteroid use were reported in 1258 individuals. Headache (n = 143), epistaxis (n = 124) and anosmia (n = 57) were reported most frequently. Nasal septum perforation (reporting odds ratio 463.2; 95% confidence interval: 186.7-1149.7) had the highest reporting odds ratio, followed by nasal mucosal disorder (reporting odds ratio 104.5; 95% confidence interval 36.3-301.3) and hyposmia (reporting odds ratio 90.8; 95% confidence interval 45.1-182.7). Moreover, 101 (4.5%) reports were classified as serious by Lareb, including reports of Cushing's syndrome, adrenal cortical hypofunction and growth retardation. CONCLUSIONS: Many side effects are consistent with the safety information in the summary of product characteristics of intranasal corticosteroids. Several serious (systemic) side effects are reported and it is important to realise that intranasal corticosteroids may contribute to the development. Healthcare providers and patients should be aware of the potential (individual) adverse drug reactions of intranasal corticosteroids. This information could help in discussing treatment options

Monitoring of somatic parameters at outpatient departments for mood and anxiety disorders

INTRODUCTION: Somatic complications account for the majority of the 13-30 years shortened life expectancy in psychiatric patients compared to the general population. The study aim was to assess to which extent patients visiting outpatient departments for mood and anxiety disorders were monitored for relevant somatic comorbidities and (adverse) effects of psychotropic drugs-more specifically a) metabolic parameters, b) lithium safety and c) ECGs-during their treatment. METHODS: We performed a retrospective clinical records review and cross-sectional analysis to assess the extent of somatic monitoring at four outpatient departments for mood and anxiety disorders in The Netherlands. We consecutively recruited adult patients visiting a participating outpatient department between March and November 2014. The primary outcome was percentage of patients without monitoring measurements. Secondary outcomes were number of measurements per parameter per patient per year and time from start of treatment to first measurement. RESULTS: We included 324 outpatients, of whom 60.2% were female. Most patients were treated for depressive disorders (39.8%), anxiety disorders (16.7%) or bipolar or related disorders (11.7%) and 198 patients (61.1%) used at least one psychotropic drug. For 186 patients (57.4%), no monitoring records were recorded (median treatment period 7.3 months, range 0-55.6). The median number of measurements per parameter per year since the start of outpatient treatment for patients with monitoring measurements was 0.31 (range 0.0-12.9). The median time to first monitoring measurement per parameter for patients with monitoring measurements was 3.8 months (range 0.0-50.7). DISCUSSION: Somatic monitoring in outpatients with mood and anxiety disorders is not routine clinical practice. Monitoring practices need to be improved to prevent psychiatric outpatients from undetected somatic complications

The Quality of Instructional YouTube Videos for the Administration of Intranasal Spray:Observational Study

BACKGROUND: Allergic rhinitis is a common disorder affecting both children and adults. Recommended treatment consists of intranasal corticosteroid spray administration, but only few patients administer the nasal spray in the correct technical manner. A wrong administration technique may result in side effects and affect the efficacy and adherence, thus making accurate administration instructions indispensable. Unfortunately, information about intranasal drug administration is generally not explained accurately, thereby leading to confusion among patients and inaccuracy in the self-administration of drugs. OBJECTIVE: In this study, we analyzed instructional videos available on YouTube for the administration of nasal sprays for allergic rhinitis. Our aim was to determine if the videos provided instructions in accordance with the standardized nationwide patient protocol in the Netherlands for intranasal spray administration. METHODS: Instructional videos for the administration of aqueous formulations of nasal spray for allergic rhinitis were found on YouTube. All videos were reviewed by 2 researchers and scored using the instructions from the Dutch standardized protocol. Correct instructions were given a score of 1, while incorrect or missing instructions were given a score of 0. The interrater reliability using Cohen ĸ was used to determine the differences in the scores between the researchers. RESULTS: We identified 33 YouTube videos made by different health care professionals and pharmaceutical companies around the world. None of the videos displayed all the steps correctly, while 5 of the 33 (15%) videos displayed over 75% of the steps correctly. The median score of the correctly displayed steps was 11 out of 19 (range 2-17, IQR 6). The interrater reliability using Cohen ĸ was statistically significant (range 0.872-1.00, P<.001). The steps "neutral position of the head," "breathing out through the mouth," and "periodically cleaning with water" scored the lowest and were incorrectly displayed in 28 (85%), 28 (85%), and 30 (91%) of the 33 videos, respectively. CONCLUSIONS: The findings of our study revealed that only few instructional videos on YouTube provided correct instructions for the administration of nasal sprays to patients. The inaccuracy of the instructions for nasal spray administration in the majority of the videos may lead to confusion in patients and incorrect use of nasal sprays. In the future, it is important to make evidence-based instructional videos that show patients the correct technique of nasal spray administration. TRIAL REGISTRATION: Not applicable

Applicability of somatic monitoring instructions in clinical practice guidelines on antipsychotic drug use

BACKGROUND: Clinical practice guidelines (CPGs) recommend the monitoring of somatic parameters in patients treated with antipsychotic drugs in order to detect adverse effects. The objective of this study was to assess, in adult and (frail) elderly populations, the consistency and applicability of the somatic monitoring instructions recommended by established CPGs prior to and during antipsychotic drug use. METHODS: A search for national and international CPGs was performed by querying the electronic database PubMed and Google. Somatic monitoring instructions were assessed for adult and (frail) elderly populations separately. The applicability of somatic monitoring instructions was assessed using the Systematic Information for Monitoring (SIM) score. Somatic monitoring instructions were considered applicable when a minimum SIM score of 3 was reached. RESULTS: In total, 16 CPGs were included, with a total of 231 somatic monitoring instructions (mean: 14; range: 0-47). Of the somatic monitoring instructions, 87% were considered applicable, although critical values and how to respond to aberrant values were only present in 28 and 52% of the available instructions respectively. Only 1 CPG presented an instruction specifically for (frail) elderly populations. CONCLUSIONS: We emphasize the need for a guideline with somatic monitoring instructions based on the SIM definition for both adult and (frail) elderly populations using antipsychotic drugs. In addition, CPGs should state that clear agreements should be made regarding who is responsible for interventions and somatic monitoring prior to and during antipsychotic drug use

Effects of ketanserin on microcirculatory alterations in septic shock:An open-label pilot study

INTRODUCTION: Microcirculatory alterations in sepsis are associated with increased morbidity and mortality. These alterations occur despite macrohemodynamic resuscitation. Alternative pro-microcirculatory strategies, including vasodilatory drugs, have been suggested to improve capillary blood flow. Ketanserin, a serotonin receptor antagonist, is an attractive candidate because of its vasodilatory, antithrombotic, and anti-inflammatory effects. METHODS: This is an open-label pilot study on the effect of ketanserin administration on microcirculatory alterations in septic shock, defined as microvascular flow index (MFI) ≤ 2.5 after a strict macrohemodynamic resuscitation protocol. Sidestream dark-field imaging was applied to assess the microcirculation. A stepwise incremental dose regiment was applied until an MFI > 2.9, the primary end point, was reached. RESULTS: Ten patients (Acute Physiology and Chronic Health Evaluation IV scores of 115 [100-136]) were included. Baseline MFI was 1.71 (1.31-2.32) and was significantly increasing to 2.96 (2.54-3.00; P = .021) during the ketanserin infusion. The total ketanserin dose was 0.09 (0.08-0.13) mg/kg per patient in 60 (30-60) minutes. In 3 patients (30%), the ketanserin infusion was discontinued due to refractory hypotension. CONCLUSION: An improvement in microcirculatory perfusion was observed during ketanserin administration in patients with septic shock after macrohemodynamic resuscitation. This finding needs further exploration in a placebo-controlled setting
