Rhinosporidiosis – factors predicting disease recurrence

Mycoses. 2021 Oct 16. doi: 10.1111/myc.13381. Online ahead of print.

ABSTRACT

BACKGROUND: Rhinosporidiosis is a chronic granulomatous disease of the nose caused by Rhinosporidium seeberi. The disease is largely non amenable to medical therapy and shows high recurrence rates requiring patients to undergo multiple surgeries often resulting in increased morbidity.

OBJECTIVE: To analyze the epidemiological, clinical, histopathological characteristics, treatment and outcome in rhinosporidiosis and to identify factors which predispose to recurrence of the disease.

PATIENTS/METHODS: Retrospective analysis of data of all patients with a diagnosis of rhinosporidiosis confirmed by histopathology at a tertiary care hospital from 2015 to 2019.

RESULTS: There were 42 patients, 40 males and two females, with a mean age of 37.37 years. Disease showed bilateral involvement in 17 (40.48%) patients. Nineteen (45.24%) patients had more than two sites involved at initial presentation. Most patients had nasal cavity involvement followed by nasopharynx. Among the 28 patients who had a follow up, 12 showed recurrent disease. However, 21 patients were disease free following a revision excision. Involvement of more than two sites was an independent significant factor for recurrence. On univariate analysis, other factors which showed statistically significant odds of developing recurrence were previous surgery (p=0.054), involvement of nasal septum (p=0.022), middle turbinate (p=0.024), nasopharynx (p=0.049) and posterior pharyngeal wall (p=0.05). Factors which showed significantly less likelihood of developing a recurrence included patients who had less than 12 months duration from first symptom to intervention (p=0.016), involvement of less than two sites (p=0.0003) and unilateral disease (p=0.019).

CONCLUSION: Early intervention in rhinosporidiosis especially when the disease is unilateral and involves less than two sites improves the outcome.

Cost-effectiveness of exergaming compared to regular day-care activities in dementia: Results of a randomised controlled trial in The Netherlands

Health Soc Care Community. 2021 Oct 17. doi: 10.1111/hsc.13608. Online ahead of print.

ABSTRACT

The growing number of people living with dementia will result in increased costs of dementia worldwide. The e-Health intervention ‘Exergaming’ may improve health and quality of life of people with dementia, but the cost-effectiveness is unknown. We assessed the cost-effectiveness of exergaming compared to regular activities from a societal perspective in day-care centres (DCC) for people with dementia and their informal caregivers (IC) alongside a cluster randomised controlled trial. We included 112 dyads (person with dementia and IC) from 20 psychogeriatric DCCs (11 exergaming, 9 control) across the Netherlands. Exergaming consisted of interactive cycling at least twice a week for 6 months. Measurements were conducted at baseline (T0), after 3 (T1) and 6 (T2) months. Primary outcomes were minutes of physical activity, mobility of the participants with dementia (Short Physical Performances Battery, SPPB), and Quality-Adjusted Life-Years (QALYs) of participants with dementia and ICs. ICs filled out cost diaries to measure healthcare and informal care utilisation during the study. There were no statistically significant differences in outcomes or costs between the groups at the level of participants with dementia, the ICs or the dyad. With regard to QALYs and SPPB, the probability that exergaming is cost-effective compared to control was low for all possible willingness-to-pay (WTP) thresholds. However, for physical activity at WTP thresholds of 0, 50 and 250 Euros per additional minute of physical activity, the probability of cost-effectiveness is 0.46, 0.84 and 0.87, respectively. Exergaming in DCC was not cost-effective compared to usual activities. However, considering the small sample size and the large number of missing observations, findings should be interpreted with caution. Future studies with larger samples are recommended to obtain definitive answers on the cost-effectiveness of exergaming. This trial was registered in the Netherlands Trial Register (NTR5537/NL5420).

A Guide to Pre-Processing High-Throughput Animal Tracking Data

J Anim Ecol. 2021 Oct 17. doi: 10.1111/1365-2656.13610. Online ahead of print.

ABSTRACT

1. Modern, high-throughput animal tracking increasingly yields ‘big data’ at very fine temporal scales. At these scales, location error can exceed the animal’s step size, leading to mis-estimation of behaviours inferred from movement. ‘Cleaning’ the data to reduce location errors is one of the main ways to deal with position uncertainty. Though data cleaning is widely recommended, inclusive, uniform guidance on this crucial step, and on how to organise the cleaning of massive datasets, is relatively scarce. 2. A pipeline for cleaning massive high-throughput datasets must balance ease of use and computationally efficiency, in which location errors are rejected while preserving valid animal movements. Another useful feature of a pre-processing pipeline is efficiently segmenting and clustering location data for statistical methods, while also being scalable to large datasets and robust to imperfect sampling. Manual methods being prohibitively time consuming, and to boost reproducibility, pre-processing pipelines must be automated. 3. We provide guidance on building pipelines for pre-processing high-throughput animal tracking data to prepare it for subsequent analyses. We apply our proposed pipeline to simulated movement data with location errors, and also show how large volumes of cleaned data can be transformed into biologically meaningful ‘residence patches’, for exploratory inference on animal space use. We use tracking data from the Wadden Sea ATLAS system (WATLAS) to show how pre-processing improves its quality, and to verify the usefulness of the residence patch method. Finally, with tracks from Egyptian fruit bats (Rousettus aegyptiacus), we demonstrate the pre-processing pipeline and residence patch method in a fully worked out example. 4. To help with fast implementation of standardised methods, we developed the R package atlastools, which we also introduce here. Our pre-processing pipeline and atlastools can be used with any high-throughput animal movement data in which the high data-volume combined with knowledge of the tracked individuals’ movement capacity can be used to reduce location errors. atlastools is easy to use for beginners, while providing a template for further development. The common use of simple yet robust pre-processing steps promotes standardised methods in the field of movement ecology and leads to better inferences from data.

Young carers and educational engagement: Quantitative analysis of bursary applications in Australia

Health Soc Care Community. 2021 Oct 17. doi: 10.1111/hsc.13589. Online ahead of print.

ABSTRACT

Young carers support family members affected by disability or a health condition. The Young Carer Bursary Program aims to support young carers’ education. This paper analysed data from consenting bursary applicants (2017-2019) to investigate relationships between wellbeing, educational attendance, home study and other factors. Descriptive statistics, correlation and regression analysis determined significant issues, relationships and influential factors related to young carer (N = 1,443) wellbeing and education. Sixty-eight percent were aged between 13 and 18 years and attended secondary school. One third of the sample reported that they were the main carer in their family and 29% reported receiving no support. Female applicants from single parent households who were the main carer attended educational settings less often. Eighteen percent (n = 267) rated their wellbeing as poor/very poor. Better wellbeing was associated with increased educational attendance (rs = 0.33, p < 0.001) and home study (rs = 0.34, p < 0.001). Wellbeing was associated with main carer status, caring for a parent, having a disability, being older and having few supports. Educational attendance was associated with main carer status, higher care load and fewer supports. Home study was associated with having a disability, caring for a sibling, caring for more than 11 hr per week and having fewer supports. Important factors about the age, life situation and challenges experienced by young carers identified in this paper indicate that further research into preferred supports and effectiveness of the bursary in improving educational engagement is warranted.

A proposed approach for the determination of the bioequivalence acceptance range for narrow therapeutic index drugs in the European Union

Clin Pharmacol Ther. 2021 Oct 17. doi: 10.1002/cpt.2451. Online ahead of print.

ABSTRACT

The current regulatory criterion for bioequivalence of narrow therapeutic index (NTI) drugs in the European Union requires that the 90% confidence interval for the ratio of the population geometric means of the test product compared to the reference for AUC, and in certain cases Cmax , to be included within the tighter acceptance range of 90.00 – 111.11%. As a consequence, sponsors need to recruit a higher number of subjects to demonstrate bioequivalence and this may be seen as increasing the burden for the development of generics. This “one-size-fits-all” criterion is particularly questionable when the within-subject variability of the reference product is moderate-to-high. As an alternative, we propose a further refined statistical approach where the acceptance range is narrowed based on the within-subject variability of the reference product of the NTI drug, similar to the one used for widening the standard 80.00 – 125.00% acceptance range for highly variable drugs. The 80.00-125.00% acceptance range is narrowed, only if the within-subject variability is lower than 30%, down to the current NTI acceptance range of 90.00 – 111.11% when the within-subject variability is 13.93% or lower. Examples within the current EMA list of NTI drugs show a considerable reduction in required sample size for drugs like Tacrolimus and Colchicine, where the predicted within-subject variability is 20-30%. In these cases, this approach is less sample size demanding without any expected increase in the therapeutic risks, since patients treated with reference products with moderate-to-high within-subject variability are frequently exposed to bioavailability differences larger than 10%.

Using Machine Learning to Advance Disparities Research: Subgroup Analyses of Access to Opioid Treatment

Health Serv Res. 2021 Oct 17. doi: 10.1111/1475-6773.13896. Online ahead of print.

ABSTRACT

OBJECTIVE: To operationalize an intersectionality framework using a novel statistical approach and with these efforts, improve the estimation of disparities in access (i.e., wait time to treatment entry) to opioid use disorder (OUD) treatment beyond race.

DATA SOURCE: Sample of 941,286 treatment episodes collected in 2015-2017 in the United States from the Treatment Episodes Data Survey (TEDS-A) and a subset from California (n = 188,637) and Maryland (n = 184,276), states with the largest sample of episodes.

STUDY DESIGN: This retrospective subgroup analysis used a two-step approach called virtual twins. In step 1, we trained a classification model that gives the probability of waiting (1 day or more). In step 2, we identified subgroups with a higher probability of differences due to race. We tested three classification models for step 1 and identified the model with the best estimation.

DATA COLLECTION: Client data were collected by states during personal interviews at admission and discharge.

PRINCIPAL FINDINGS: Random forest was the most accurate model for the first step of subgroup analysis. We found large variation across states in racial disparities. Stratified analysis of two states with the largest samples showed critical factors that augmented disparities beyond race. In California, factors such as service setting, referral source, and homelessness defined the subgroup most vulnerable to racial disparities. In Maryland, service setting, prior episodes, receipt of medication-assisted opioid treatment, and primary drug use frequency augmented disparities beyond race. The identified subgroups had significantly larger racial disparities.

CONCLUSIONS: The methodology used in this study enabled a nuanced understanding of the complexities in disparities research. We found state and service factors that intersected with race and augmented disparities in wait time. Findings can help decision makers target modifiable factors that make subgroups vulnerable to waiting longer to enter treatment. This article is protected by copyright. All rights reserved.

Calcium channel blockers versus other classes of drugs for hypertension

Cochrane Database Syst Rev. 2021 Oct 17;10:CD003654. doi: 10.1002/14651858.CD003654.pub5.

ABSTRACT

BACKGROUND: This is the first update of a review published in 2010. While calcium channel blockers (CCBs) are often recommended as a first-line drug to treat hypertension, the effect of CCBs on the prevention of cardiovascular events, as compared with other antihypertensive drug classes, is still debated.

OBJECTIVES: To determine whether CCBs used as first-line therapy for hypertension are different from other classes of antihypertensive drugs in reducing the incidence of major adverse cardiovascular events.

SEARCH METHODS: For this updated review, the Cochrane Hypertension Information Specialist searched the following databases for randomised controlled trials (RCTs) up to 1 September 2020: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2020, Issue 1), Ovid MEDLINE, Ovid Embase, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also contacted the authors of relevant papers regarding further published and unpublished work and checked the references of published studies to identify additional trials. The searches had no language restrictions.

SELECTION CRITERIA: Randomised controlled trials comparing first-line CCBs with other antihypertensive classes, with at least 100 randomised hypertensive participants and a follow-up of at least two years.

DATA COLLECTION AND ANALYSIS: Three review authors independently selected the included trials, evaluated the risk of bias, and entered the data for analysis. Any disagreements were resolved through discussion. We contacted study authors for additional information.

MAIN RESULTS: This update contains five new trials. We included a total of 23 RCTs (18 dihydropyridines, 4 non-dihydropyridines, 1 not specified) with 153,849 participants with hypertension. All-cause mortality was not different between first-line CCBs and any other antihypertensive classes. As compared to diuretics, CCBs probably increased major cardiovascular events (risk ratio (RR) 1.05, 95% confidence interval (CI) 1.00 to 1.09, P = 0.03) and increased congestive heart failure events (RR 1.37, 95% CI 1.25 to 1.51, moderate-certainty evidence). As compared to beta-blockers, CCBs reduced the following outcomes: major cardiovascular events (RR 0.84, 95% CI 0.77 to 0.92), stroke (RR 0.77, 95% CI 0.67 to 0.88, moderate-certainty evidence), and cardiovascular mortality (RR 0.90, 95% CI 0.81 to 0.99, low-certainty evidence). As compared to angiotensin-converting enzyme (ACE) inhibitors, CCBs reduced stroke (RR 0.90, 95% CI 0.81 to 0.99, low-certainty evidence) and increased congestive heart failure (RR 1.16, 95% CI 1.06 to 1.28, low-certainty evidence). As compared to angiotensin receptor blockers (ARBs), CCBs reduced myocardial infarction (RR 0.82, 95% CI 0.72 to 0.94, moderate-certainty evidence) and increased congestive heart failure (RR 1.20, 95% CI 1.06 to 1.36, low-certainty evidence).

AUTHORS’ CONCLUSIONS: For the treatment of hypertension, there is moderate certainty evidence that diuretics reduce major cardiovascular events and congestive heart failure more than CCBs. There is low to moderate certainty evidence that CCBs probably reduce major cardiovascular events more than beta-blockers. There is low to moderate certainty evidence that CCBs reduced stroke when compared to angiotensin-converting enzyme (ACE) inhibitors and reduced myocardial infarction when compared to angiotensin receptor blockers (ARBs), but increased congestive heart failure when compared to ACE inhibitors and ARBs. Many of the differences found in the current review are not robust, and further trials might change the conclusions. More well-designed RCTs studying the mortality and morbidity of individuals taking CCBs as compared with other antihypertensive drug classes are needed for patients with different stages of hypertension, different ages, and with different comorbidities such as diabetes.

Child physical abuse: knowledge of dental students in Hamburg, Germany

Eur Arch Paediatr Dent. 2021 Oct 16. doi: 10.1007/s40368-021-00651-0. Online ahead of print.

ABSTRACT

PURPOSE: This study was aimed at evaluating the levels of knowledge of child abuse among students attending the School of Dental and Oral Medicine at the University of Hamburg- Eppendorf, Germany.

METHODS: This cross-sectional study utilized a self-administered and structured questionnaire, consisting of 23 multiple-choice questions; the questionnaire focused on rating the students’ knowledge of and ability to diagnose child abuse. Each question was analysed with simple descriptive statistics.

RESULTS: The students (181) were aware of their legal and ethical responsibilities towards the children and their parents. More than two-thirds (69.6%) responded positively when asked whether a dentist should be legally responsible to report cases of child abuse brought to their attention. The majority of the students (96.1%) agreed that dentists had an ethical duty to report such cases. However, the students were unable to define or describe the signs, symptoms, and social indicators of child abuse. Approximately 93.4% of the students lacked basic training related to child abuse, while 95.7% of them indicated that there was insufficient training in issues related to child abuse.

CONCLUSIONS: There is a general lack of information regarding child abuse among dentistry students. The majority of the students showed interest in the topic of child abuse and neglect, but were unable to clearly identify the signs and symptoms. More lectures and workshops relating to child abuse should be available to all dentists to reinforce their knowledge as well as to strengthen their confidence when confronted with suspected cases of child abuse.

Under-Vaccination in Adults: Qualitative Insights Into Perceived Barriers Reported by Vaccine Supporters, Undecided and Refuters

J Prim Prev. 2021 Oct 17. doi: 10.1007/s10935-021-00650-3. Online ahead of print.

ABSTRACT

Although vaccination is one of the most cost-effective ways of preventing disease, vaccine hesitancy has been included among the ten threats of global health. Addressing low adult vaccination rates requires an adequate understanding of people’s views. We explored perceived barriers to immunization among under-vaccinated adults to identify potential differences among vaccine supporters, refuters, and those who are undecided. We conducted a multi-center, mixed-methods study at 23 primary care practices in Greece. Each day, we asked three new randomly-selected adult healthcare users who attended the practice over the course of 30 consecutive working days. We used thematic content analysis to analyze their written answers to open-ended questions that addressed reasons for not getting vaccinated. Out of 1571 participants, two-thirds reported they were under-vaccinated as adults, thus accounting for three out of five of the supporters and the vast majority of the undecided and refuters. “Concerns/fears,” a “perception of low susceptibility to disease due to good health status,” the “absence of healthcare professional’s recommendation,” and “previous negative experiences” were four themes common to all three groups. Additional barriers reported by supporters and the undecided included “knowledge gaps about the necessity of adult vaccination,” “negligence,” and lack of “accessibility.” Among refuters, additional themes identified were “mistrust in pharmaceutical companies” and “disbelief in vaccine effectiveness.” In conclusion, under-vaccination is common, not only among refuters or the undecided, but also among supporters of adult vaccination. We found similarities and differences in under-vaccinated adults’ perceived barriers, depending on their individual perspectives. Physicians and public health services should take into consideration the impact of the wide range of attitudes and beliefs in their effort to address the underlying barriers to vaccination compliance as they attempt to increase vaccination coverage in adults.

Efficacy, Safety and Immunogenicity of AVT02 Versus Originator Adalimumab in Subjects with Moderate to Severe Chronic Plaque Psoriasis: A Multicentre, Double-Blind, Randomised, Parallel Group, Active Control, Phase III Study

BioDrugs. 2021 Oct 16. doi: 10.1007/s40259-021-00502-w. Online ahead of print.

ABSTRACT

BACKGROUND: AVT02 (adalimumab) is a proposed biosimilar to Humira®. AVT02 is produced at a 100 mg/mL concentration with a citrate-free formulation.

OBJECTIVES: The aim of this study was to compare the efficacy, safety and immunogenicity of AVT02 versus Humira® in subjects with moderate to severe chronic plaque psoriasis.

METHODS: This double-blind, randomised, parallel group, active control study of adult subjects compared (at a 1:1 ratio) AVT02 with originator adalimumab 80 mg subcutaneously in Week 1, then 40 mg every other week. At Week 16, subjects who had received originator adalimumab were re-randomised at a 1:1 ratio to continue receiving originator adalimumab, or to switch to AVT02, every other week until Week 48, with final efficacy endpoint at Week 50. Subjects who initially received AVT02 continued to receive AVT02 from Week 16 to Week 48. The primary endpoint was percentage improvement in Psoriasis Area and Severity Index (PASI) score at Week 16. Secondary efficacy endpoints included percentage improvement in PASI score at additional timepoints, change from baseline in Dermatology Life Quality Index (DLQI) score and number and percentage of subjects achieving static Physician’s Global Assessment (sPGA) responses of ‘clear’ or ‘almost clear’. Additional secondary endpoints included comparison of adverse event profiles, anti-drug antibodies and neutralising antibodies, and serum trough levels of adalimumab at steady state.

RESULTS: A total of 413 subjects were randomised (205 to AVT02 and 208 to originator). The percentage improvement in PASI score at Week 16 was 91.6% for AVT02-treated subjects and 89.6% for originator adalimumab. The 90% confidence intervals for the primary endpoint were within the pre-defined equivalence margin of ±10% (90% CI – 0.76 to 5.29; 95% CI – 1.34 to 5.88), and a comparable pattern for DLQI score (11.4-point and 10.6-point improvement in AVT02-treated and originator adalimumab-treated groups, respectively) and sPGA (90.5% in both groups achieving ‘clear’ or ‘almost clear’) at Week 16 supported the assessment. Efficacy persisted through Week 50 of the study in all treatment groups, including those who switched from originator adalimumab to AVT02, for percent improvement in PASI score, quality-of-life assessment and sPGA. The safety, tolerability and immunogenicity profiles between AVT02 and originator adalimumab were similar at Week 16, and this persisted in the switched and continued groups through Week 50.

CONCLUSION: Objective and subjective measures of efficacy supported the evaluation of biosimilarity between AVT02 and originator adalimumab at Week 16 and until Week 50, in switched and continued treatment groups. AVT02 was safe and well tolerated, with a safety and immunogenicity profile similar to that observed in originator adalimumab with no clinically meaningful difference between the two.
