Radioiodine treatment of hyperthyroidism in cats: results of 165 cats treated by an individualised dosing algorithm in Spain
Authors: Xifra Pilar , Serrano Sara I , Peterson Mark E 
Published: June 2022

Objectives Although radioiodine (131I) is the treatment of choice for feline hyperthyroidism, 131I-dosing protocols commonly induce iatrogenic hypothyroidism and expose azotaemia. A recently reported patient-specific 131I dosing algorithm minimised the risk of 131I-induced hypothyroidism and azotaemia, while maintaining high cure rates. The aim of the study was to report results of 131I treatment in a European population of hyperthyroid cats using this patient-specific dosing algorithm. Methods This prospective case series (before-and-after study) evaluated 165 hyperthyroid cats referred for 131I treatment. All cats had serum concentrations of thyroxine (T4), triiodothyronine (T3) and thyroid-stimulating hormone (TSH) measured (off methimazole ⩾1 week). Thyroid volume and percentage uptake of 99mTc-pertechnetate (TcTU) were determined using thyroid scintigraphy. An initial 131I dose was calculated by averaging dose scores for T4/T3 concentrations, thyroid volume and TcTU; 70% of that composite dose was then administered. Twenty-four hours later, percentage 131I uptake was measured, and additional 131I administered as needed to deliver an adequate radiation dose to the thyroid tumour(s). Serum concentrations of T4, TSH and creatinine were determined 6–12 months later. Results Median calculated 131I dose was 2.15 mCi (range 1.2–7.5), with only 51 (30.9%) receiving ⩾2.5 mCi. Of 165 cats, 124 (75.2%) became euthyroid, seven (4.2%) became overtly hypothyroid, 27 (16.4%) became subclinically hypothyroid and seven (4.2%) remained hyperthyroid. A higher proportion of overtly (85.7%) and subclinically (26.9%) hypothyroid cats developed azotaemia than euthyroid cats (13.6%; P = 0.0002). Hypothyroid cats were older ( P = 0.016) and more likely to have detectable TSH concentrations ( P = 0.025) and symmetrical bilateral distribution of 99mTc-pertechnetate uptake ( P = 0.0002), whereas persistently hyperthyroid cats had higher severity scores ( P = 0.012). Conclusions and relevance Our results confirm that 131I dosing with this new algorithm results in high cure rates, with a lowered prevalence of 131I-induced overt hypothyroidism and azotaemia. Age, serum TSH concentrations, bilateral, symmetrical uptake and severity score help predict outcome.

Published: June 2022

Objectives A urine culture is often pursued in cats with acute kidney injury (AKI) to screen for bacterial growth in the urine, but it can be cost prohibitive. The aim of the study was to determine the ability of a urinalysis and lower urinary tract signs (LUTS) to predict urine culture results in cats with AKI. Methods Ninety-seven cats with AKI were included in this study. This was a retrospective, observational study. Medical records from 2008 to 2018 were reviewed to identify cats with AKI that had a paired urinalysis and urine bacterial culture. The sensitivity, specificity, positive predictive value and negative predictive values of microscopic bacteriuria, pyuria, hematuria and the presence of LUTS for predicting urine culture results was calculated. Results Thirty-two percent of cats (n = 31) had a positive urine culture. Of these, 28 (90%) had bacteriuria, 21 (68%) had pyuria, 13 (42%) had hematuria and 10 (32%) had LUTS. Of the 42 cats without hematuria or pyuria, seven had a positive urine culture (17%). Bacteriuria had a high sensitivity (90%) and specificity (92%) for predicting urine culture bacterial growth. The absence of bacteriuria had a high negative predictive value for no bacterial growth (95%). The odds of a positive urine culture were increased with bacteriuria (odds ratio [OR] 114, 95% confidence interval [CI] 29–621; P <0.001), pyuria (OR 21, 95% CI 7–70; P <0.001) and LUTS (OR 5, 95% CI 1.7–16; P = 0.004). Hematuria was not associated with a positive culture (sensitivity 42%, specificity 52%). Conclusions and relevance Microscopic bacteriuria and pyuria on urine sediment evaluation and LUTS can be helpful for predicting bacterial culture results in cats with AKI and in settings where submitting a urine culture may not be financially feasible.
Adherence to the Mediterranean Diet of Pregnant Women in Central South Africa: The NuEMI Study
Authors: Spies Hermina Catharina , Nel Mariette , Walsh Corinna May 
Published: June 2022

Introduction: The Mediterranean diet (MeD) has been shown to have significant health benefits for adults and children. A mother’s diet during pregnancy directly impacts the health of her offspring. This study aimed to investigate the adherence to the MeD of pregnant women attending antenatal care at a Regional Hospital in Bloemfontein, South Africa (SA). Methods: A cross-sectional study was conducted on a consecutive sample of 681 pregnant women who attended the antenatal clinic of a Regional Hospital in Bloemfontein. Socio-demographics included: age, highest level of education, household income, employment status, and income stability. Food group intake was assessed with a quantitative food frequency questionnaire. The adapted Mediterranean Diet Adherence Screener (MeDAS) consisted of 13 of the original 14 questions that measured intake of key food groups (score of ⩽7 poor, 8-9 moderate, ⩾10 good) (wine intake was excluded for pregnant women). Results: A total of 681 pregnant women with a median age of 31.8 years (IQR: 26.8-36.5 years) and a median gestational age of 32.0 weeks at the time of the interview participated in the study. The vast majority showed poor adherence to the MeD (99.6%), with only 0.4% (n = 3) having moderate adherence and 0% good adherence. The median adherence score was 5 points and the maximum 8 points. Of those with poor adherence, only 11.5% had tertiary education, 43.2% earned less than R 3000 (<201 USD) per month, 52.5% were unemployed, and 42.0% did not have a stable income in the past 6 months. Of the 3 participants with moderate adherence, all had grade 11 to 12 education, 2 out of the 3 earned more than R3000 (201 USD), one was unemployed, and 2 had a stable income over the past 6 months. Compared to those with an income ⩽ R3000 (⩽201 USD), those with an income above R3000 were significantly more likely to eat nuts (including peanuts) (2.0% vs 4.6%, P = .05), and adhere to sofrito (similar to tomato and onion relish) intake (9.2% vs 15.6%, P = .02). Compared to those who only had a primary education level up to grade 10 (n = 229), those who had a secondary education level or more (grade 11 and higher, n = 452) were significantly more likely to consume enough olive oil per day (1.3% vs 5.0%, P = .01), and to consume sofrito (6.6% vs 18.0%, P = .02). Conclusion: Pregnant participants showed poor adherence to the MeD. Although almost all women fell in the poor adherence group, secondary education contributed to consuming recommended amounts of olive oil and sofrito and higher income was associated with an adequate intake of nuts and sofrito. Based on the findings, we recommend the development of a contextualized MeDAS tool that includes foods that are typically eaten by most South Africans for similar MeD benefits.
Paramagnetic rim lesions are associated with pathogenic CSF profiles and worse clinical status in multiple sclerosis: A retrospective cross-sectional study
Authors: Hemond Christopher C , Baek Jonggyu , Ionete Carolina , Reich Daniel S 
Published: June 2022

Background: Paramagnetic rims have been observed as a feature of some multiple sclerosis (MS) lesions on susceptibility-sensitive magnetic resonance imaging (MRI) and indicate compartmentalized inflammation. Objective: To investigate clinical, MRI, and intrathecal (cerebrospinal fluid, CSF) associations of paramagnetic rim lesions (PRLs) using 3T MRI in MS. Methods: This is a retrospective, cross-sectional analysis. All patients underwent 3T MRI using a T2*-weighted sequence with susceptibility postprocessing (susceptibility-weighted angiography (SWAN) protocol, GE). SWAN-derived filtered-phase maps and corresponding T2-FLAIR images were manually reviewed to determine PRL. Descriptive statistics, t-tests, and regression determined demographic, clinical, MRI, and CSF associations with PRL. Results: A total of 147 MS patients were included; 79 of whom had available CSF. Forty-three percent had at least one PRL. PRL status (presence/absence) did not vary by sex or Expanded Disability Status Scale (EDSS) but was associated with younger age, shorter disease duration, worse disease severity, high-efficacy therapy use, and poorer dexterity, as well as lower age-adjusted brain volumes and cognitive processing speeds. PRL status was moreover associated with blood–brain barrier disruption as determined by pathologically elevated albumin quotient. Sensitivity analyses remained supportive of these findings. Conclusion: PRLs, an emerging noninvasive biomarker of chronic neuroinflammation, are confirmed to be associated with greater disease severity and newly shown to be preliminarily associated with blood–brain barrier disruption.

Published: June 2022

When planning paediatric trials, it is important to consider how best to communicate with children and young people (CYP) so they understand what they are taking part in. It is also important to consider what information they need. Involving CYP as research participants leads to research that is more relevant although it can be difficult to engage CYP in qualitative research to improve trial materials due to the topic area. This paper describes how a visual ranking exercise within qualitative interviews acted as a helpful conduit to engaging discussions to inform a co-designed website with information for trial participants. 40 people participated in interviews during which the ranking exercise was used (11 CYP aged 9–18 years, 14 parents, 15 professionals). We found the ranking exercise supported participant engagement and prevented them feeling that particular responses were expected. It also enabled participants to discuss their ranking (and decisions behind this) with other participants and the researcher. Co-design interviews with CYP that use interactive exercises such as ranking are likely to elicit richer data than those relying on traditional questioning techniques.

Objectives C-reactive protein to albumin ratio (CAR) and prognostic nutritional index (PNI) are novel parameters with proven prognostic importance in the postoperative outcomes of coronary and peripheral vascular diseases. In this study, we aimed to evaluate the ability of CAR and PNI to predict major cardiac and cerebrovascular events (MACCE) during the postoperative period of Carotid artery endarterectomy (CEA). Methods A total of 505 carotid endarterectomy patients were retrospectively evaluated. Of 505 patients, 23 patients who died and who experienced myocardial infarction or major neurologic complication in the first 30 days after the operation were included in MACCE group (Group 1). The remaining 482 patients were included in Group 2. Receiver operating characteristics (ROC) curve analysis was used to evaluate preoperative serum albumin value, lymphocytes count, PNI, and CAR to predict the MACCE. The DeLong test was used to compare the area below the curve (AUC) with each of these parameters. Results CAR (2.48 ± 1.82 and 1.64 ± 1.37) and CRP (9.98 ± 7.42 and 6.81 ± 5.70) values are statistically higher in Group 1 than in Group 2. PNI (41.59 ± 3.11 and 43.54 ± 4.20) and albumin (40.43 ± 3.15 and 42.35 ± 4.15) values were significantly lower in Group 1 than in Group 2. The accuracy of albumin (AUC: 0.669) in the prediction of MACCE was found to be the highest among CAR (AUC: 0.631), PNI (AUC:0.667), and CRP (AUC:0.631). Conclusion Preoperative nutritional and inflammatory status is significantly associated with post-operative outcomes. PNI and CAR can be used for preoperative evaluation, as CEA is recommended for patients who have low possibility of having postoperative major adverse events.

Published: June 2022

On two occasions, five surgeons classified a cohort of 150 consecutive patients with congenital upper limb anomalies according to the Oberg–Manske–Tonkin classification (2020 update). We estimated reliability for the main anomaly code by means of Cohen’s kappa (Κ) for ten rater pairs for five common and easily distinguishable anomalies (Group 1), and for all the other anomalies (Group 2). Inter-rater reliability for all patients ( n = 150) was substantial, almost perfect for Group 1 ( n = 64), but only moderate for Group 2 ( n = 86). Intra-rater reliability was higher for all groups. We suggest simplifications to the Oberg–Manske–Tonkin classification and highlight specific requirements for instructions to increase its reliability. Level of evidence: I

Purpose: We report the 5-year follow-up findings of a randomized, open-label, phase II trial of lobaplatin-based neoadjuvant chemotherapy plus adjuvant therapy for triple-negative breast cancer (TNBC). Patients and methods: This study included patients aged ⩾18 years with untreated, operable stage I–III TNBC and an Eastern Cooperative Oncology Group performance status of 0 or 1. One group of patients (TE group, n = 99) received four cycles of docetaxel (T, 75 mg/m²) plus epirubicin (E, 80 mg/m²) every 3 weeks, and another group (TEL group, n = 101) received the same treatment with the addition of lobaplatin (L, 30 mg/m2). Two cycles of the corresponding treatments were administered after surgery in both groups. The primary endpoints were total pathological complete response (tpCR) rate and overall response rate (ORR), and the secondary endpoints were disease-free survival, overall survival, and long-term safety. This trial is registered with the Chinese Clinical Trial Registry (ChiCTR-TRC-14005019). Results: The median follow-up was 48.2 months (interquartile range: 31.1–60.0). The tpCR rate was 41.4% and 17.8% in the TEL group and TE group, respectively ( p < 0.001). The HR for comparison of DFS between the TEL group and TE group was 0.44 (95% CI: 0.21–0.90, P p = 0﻿.028). The addition of lobaplatin resulted in an HR of 0.44 (95% CI: 0.18–1.02, P = 0.061) for the difference in OS between the two groups. The ORR, which included complete response and partial response, was 92.9% in the TEL group and 74.3% in the TE group ( p = 0.001). The TEL group patients were more likely to develop grade III–IV anemia and thrombocytopenia. No lobaplatin-related deaths or increased risk of long-term toxicity was observed. Conclusion: Neoadjuvant lobaplatin therapy can improve the tpCR and ORR rates of TNBC with tolerable side effects and have a tendency to improve the long-term survival.

Published: June 2022

Background: Little is known about the real-world survival benefits and safety profiles of carfilzomib–lenalidomide–dexamethasone (KRd) and carfilzomib–dexamethasone (Kd). Methods: We performed a retrospective analysis to evaluate their efficacy and safety in 157 patients registered in the Kansai Myeloma Forum database. Results: A total of 107 patients received KRd. Before KRd, 99% of patients had received bortezomib (54% were refractory disease), and 82% had received lenalidomide (57% were refractory disease). The overall response rate (ORR) was 68.2%. The median progression-free survival (PFS) and overall survival (OS) were 8.8 and 29.3 months, respectively. Multivariate analysis showed that reduction of the carfilzomib dose and non-IgG M protein were significantly associated with lower PFS and reduction of the carfilzomib dose and refractoriness to prior bortezomib-based regimens were significantly associated with lower OS. A total of 50 patients received Kd. Before Kd, 96% of patients had received bortezomib (54% were refractory disease). The ORR was 62.0%. The median PFS and OS were 7.1 and 20.9 months, respectively. Based on the multivariate analysis, reduction of the carfilzomib dose and International Staging System Stage III (ISS III) were significantly associated with lower PFS. Grade III or higher adverse events were observed in 48% of KRd cases and 54% of Kd cases. Cardiovascular events, cytopenia, and infections were frequent, and 4 KRd patients died due to heart failure, arrhythmia, cerebral hemorrhage, and pneumonia. Conclusion: Our analysis showed that an adequate dose of carfilzomib is important for achieving the best survival benefits in a real-world setting. Adverse effects after KRd and Kd therapy should also be considered.

Published: June 2022

Background: Evidence investigating sleep pattern in relation to bone health in elderly participants with osteoporosis remains sparse. We aimed to assess the relationship between sleep pattern incorporating five sleep characteristics (snoring, midnight waking up, insomnia, sleep duration, and daytime napping) and bone mineral density (BMD) in elderly participants with osteoporotic fracture. Methods: A cross-sectional study was conducted to include eligible elderly patients from the Department of Orthopedics who were admitted to hospital due to an osteoporotic fracture. Sleep pattern was constructed based on total sleep scores and categorized into healthy, intermediate, and poor pattern groups. Multivariable logistic regression model was used to assess sleep pattern in relation to risk of low BMD. Results: A total of 169 elderly patients with osteoporotic fracture were included in this study (mean age: 71.91 years; 87.57% females). There were 36 (21.30%), 107 (63.31%), and 26 (15.38%) patients with healthy, intermediate, and poor sleep pattern, respectively. Compared with healthy sleep pattern, no significant relationship between intermediate sleep pattern and BMD was detected [odds ratio (OR) = 1.72, 95% confidence interval (CI): 0.74, 3.97, p = 0.21), while poor pattern was significantly associated with decreased BMD (OR = 3.50, 95% CI: 1.10, 11.14, p = 0.034). Conclusion: The majority of elderly patients with osteoporotic fracture had unhealthy sleep pattern; poor sleep pattern was significantly related to reduced BMD when compared with healthy pattern. Further high-quality evidence is needed to assess and validate the relationship between sleep pattern and risk of low BMD in the elderly.
Effects of antipsychotics on heart rate in treatment of schizophrenia: a systematic review and meta-analysis
Authors: Huhn Maximilian , Arndt Thomas , Schneider-Thoma Johannes , Leucht Stefan 
Published: June 2022

Background: Antipsychotics are the treatment of choice in the therapy of schizophrenia. These drugs can be associated with changes in heart rate, but this question has never been examined systematically. Objective: We aimed to analyse changes in heart rate during treatment with antipsychotics using the frequency of tachycardia and bradycardia events. Design: For this systematic review and meta-analysis, we included all randomized controlled trials for the acute treatment of schizophrenia comparing antipsychotics head-to-head or with placebo. Data Sources and Methods: We searched Embase, MEDLINE, PsycINFO, PubMed, BIOSIS, Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry Platform and ClinicalTrials.gov (last search June 2021). Two authors independently selected studies and extracted data. We conducted pairwise meta-analyses using a random-effects model. Outcomes were tachycardia and bradycardia events. Results: We found 469 trials meeting the inclusion criteria. Seventy-seven studies with 16,907 participants provided data on tachycardia or bradycardia events. We found no significant differences between antipsychotics and placebo or between antipsychotics for bradycardia events based on sparse data. Antipsychotics had a higher risk for tachycardia events compared with placebo [ N = 37, n = 7827, risk ratio (RR) = 1.83, 95% confidence interval (CI) = 1.40–2.41], with large differences between the individual substances (iloperidone RR = 14.05, chlorpromazine RR = 4.84, loxapine RR = 4.52, risperidone RR = 3.38, quetiapine RR = 2.64, paliperidone RR = 1.65). Some head-to-head comparisons were also significantly different: olanzapine versus haloperidol RR = 2.87, chlorpromazine versus thiothixene RR = 2.92, quetiapine versus lurasidone RR = 3.22, risperidone versus aripiprazole RR = 4.37, iloperidone versus ziprasidone RR = 4.65). Conclusion: Many studies do not report data for cardiac outcomes, but the available evidence indicates that treatment with antipsychotics raises the risk for tachycardia. Therefore, especially patients with cardiac risk factors should be monitored closely during antipsychotic treatment. Registration: PROSPERO: CRD42014014919
