Scleral Fixation of a Hydrophobic Acrylic Intraocular Lens with Eyelets Using 8-0 Polypropylene Suture

Purpose To report clinical outcomes of a scleral fixation technique of a hydrophobic acrylic intraocular lens with eyelets using 8-0 polypropylene suture. Methods Nine eyes of nine patients who underwent combined pars plana vitrectomy and sclera fixation of an intraocular lens using this technique were analyzed. Results The mean follow-up period was 7.11 months (range, 6–12 months), and there was a significant visual improvement at 6 months after surgery. The mean logarithm of the minimum angle of the resolution changed from 0.54 at baseline to 0.29 at postoperative 6 months (p = 0.016). The mean postoperative spherical equivalent at 6 months was −0.90 ± 0.90 diopters, and the mean predictive error was −0.49 ± 0.62 diopters. Conclusions Postoperative visual and refractive outcomes were favorable, and the positions of intraocular lenses were well centered in all cases. This technique could be a useful alternative for surgeons without easy access to Gore-Tex suture.
Rupatadine protects the intestinal mucosa from injury by 5-flurouracil via modulation of inflammation, apoptosis and intestinal permeability

Abstract Fluorouracil (5-FU) is a widely used chemotherapeutic agent in various malignant tumors. However, intestinal toxicity is considered the irritant unavoidable adverse effect during the course therapy. The aim of the current study was to screen the effect of a new selective histamine receptor 1 blocker and platelet-activating factor (PAF) blocker on 5-FU induced intestinal toxicity. Five groups (6 rats each) of adult male rats (Wistar) were arranged as follows: (1) control group that was treated with carboxymethylcellulose, (2) a group that received rupatadine (higher dose) only, (3) a group that received 5-FU and (4) and (5) groups that received 5-FU plus lower or higher dose rupatadine, respectively. At end of the experiment, we determined intestinal malondialdehyde (MDA), glutathione reduced (GSH), nitric oxide (NO), tumor necrosis factor (TNF-α), interleukin 1β, 6, 10 (IL-1β, IL-6, IL-10), PAF, histamine, myeloperoxidase, cysteine-aspartic acid protease-3 (caspase-3), and nuclear factor kappa B (NF-κB) as well as the histological analysis. 5-FU injection caused marked elevation of MDA, NO, TNF-α, IL-1β, IL-6, PAF, histamine, myeloperoxidase, caspase-3, and NF-κB expressions. The intoxicated animals showed deficient GSH and IL-10 along with significant loss of villi, disorganized crypts, and inflammatory cell infiltration. Rupatadine pretreatment reduced the previously mentioned parameters, preserved a nearly normal intestinal mucosa picture with replenished GSH and elevated IL-10. In conclusion, rupatadine is a dual histamine receptor 1, and a PAF blocker could reduce 5-FU-induced oxidative damage, inflammation, apoptosis, and ulceration of the intestinal epithelium. Rupatadine may be a valuable modality to decrease 5-FU induced intestinal mucositis.
The dynamic theory of reasoned action: evidence for a reverse causal process in the context of WHO handwashing guidelines

Abstract Objective This study provided a first empirical test of the Reverse Dynamic Theory of Reasoned Action (RDTRA) developed by Boster et al. Design In a longitudinal experiment, 169 participants were exposed to a WHO handwashing-guidelines behavioural induction, followed by an immediate posttest and a follow-up one week later. Main outcome measures The study measured attitudes and norms about WHO handwashing guidelines, as well as self-reported handwashing behaviour. Results The experimental induction produced variance in self-reported handwashing behaviour, allowing a test of the RDTRA using path analysis and structural equation modelling (SEM). Results were consistent with the RDTRA, with a positive effect of behaviour on both the attitude and norm coupled with excellent model fit. Results were inconsistent with behaviour as an outcome of attitudes and norms in this context. Conclusion For health behaviours, such as the WHO handwashing technique, initial behavioural adoption may promote subsequent shaping of attitudes and perceived norms. Boundary conditions for this effect may include the degree of spontaneity and consent involved in behaviour adoption.
A Quality Improvement Project on Pain Management at a Tertiary Pediatric Hospital

To assess and improve pain management practices for hospitalized children in an urban tertiary pediatric teaching hospital. Methods Health Quality Ontario Quality Improvement (QI) framework informed this study. A pre (T1) – post (T2) intervention assessment included chart reviews and children/caregiver surveys to ascertain pain management practices. Information on self-reported pain intensity, painful procedures, pain treatment and satisfaction were obtained from children/caregivers. Documented pain assessment, pain scores, and pharmacological/non-pharmacological pain treatments were collected by chart review. T1 data was fed back to pediatric units to inform their decisions and pain management targets. Results At T1, 51 (58% of eligible participants) children/caregivers participated. At T2, 86 (97%) chart reviews and 51 (54%) children/caregivers surveys were completed. Most children/caregivers at T1 (78%) and T2 (80%) reported moderate to severe pain during their hospitalization. A mean of 2.6 painful procedures were documented in the previous 24 h, with the most common being needle-related procedures at both T1 and T2. Pain management strategies were infrequently used during needle-related procedures at both time points. Conclusion No improvements in pain management as measured by the T1 and T2 data occurred. Findings informed further pain management initiatives in the participating hospital.
Serum Selenium Levels in Patients with Graves Disease: Associations with Clinical Activity and Severity in a Retrospective Case-control Study

Purpose To compare serum selenium levels in Graves patients and non-Graves control participants and to evaluate associations between serum selenium levels and clinical features of Graves orbitopathy (GO). Methods We conducted a single-center, retrospective case-control study among 33 patients with Graves disease without GO (GD), 31 patients with diagnosed GO, and 27 unaffected healthy participants enrolled between 2013 and 2020 at Severance Hospital. We compared serum selenium concentrations between the GD, GO, and healthy control groups, and analyzed associations between serum selenium and GO patients’ clinical activity scores, severity (assessed through modified NOSPECS scores), and other clinical features using multivariate linear regression analysis. Results Mean serum selenium levels were 109.30 ± 16.39, 111.39 ± 14.04, and 126.09 ± 21.09 ng/mL in GO patients, GD patients, and healthy control participants, respectively. Mean serum selenium levels in Graves patients with and without orbitopathy were significantly lower than those in the healthy control group (p < 0.05), and mean selenium levels were slightly lower in GO than those in GD patients (p = 0.594). Serum selenium levels were significantly lower in GO patients with eyelid retraction than in patients without retraction (p = 0.038). However, serum selenium levels were not associated with clinical activity scores and modified NOSPECS scores (p = 0.241 and 0.801, respectively). Conclusions Serum selenium levels were significantly lower in Graves patients with or without GO, compared to non-Graves control participants. Selenium levels were not associated with clinical activity scores or NOSPECS scores, though we observed an association with eyelid retraction.
The effects of the pandemic on mental health in persons with and without a psychiatric history

Abstract Background Prospective studies are needed to assess the influence of pre-pandemic risk factors on mental health outcomes following the COVID-19 pandemic. From direct interviews prior to (T1), and then in the same individuals after the pandemic onset (T2), we assessed the influence of personal psychiatric history on changes in symptoms and wellbeing. Methods Two hundred and four (19–69 years/117 female) individuals from a multigenerational family study were followed clinically up to T1. Psychiatric symptom changes (T1-to-T2), their association with lifetime psychiatric history (no, only-past, and recent psychiatric history), and pandemic-specific worries were investigated. Results At T2 relative to T1, participants with recent psychopathology (in the last 2 years) had significantly fewer depressive (mean, M = 41.7 v. 47.6) and traumatic symptoms (M = 6.6 v. 8.1, p < 0.001), while those with no and only-past psychiatric history had decreased wellbeing (M = 22.6 v. 25.0, p < 0.01). Three pandemic-related worry factors were identified: Illness/death, Financial, and Social isolation. Individuals with recent psychiatric history had greater Illness/death and Financial worries than the no/only-past groups, but these worries were unrelated to depression at T2. Among individuals with no/only-past history, Illness/death worries predicted increased T2 depression [B = 0.6(0.3), p < 0.05]. Conclusions As recent psychiatric history was not associated with increased depression or anxiety during the pandemic, new groups of previously unaffected persons might contribute to the increased pandemic-related depression and anxiety rates reported. These individuals likely represent incident cases that are first detected in primary care and other non-specialty clinical settings. Such settings may be useful for monitoring future illness among newly at-risk individuals.
Determination of Margins for Tumor Clearance in Dermatofibrosarcoma Protuberans: A Single-Center Study of 222 Cases Treated With Modified Mohs Surgery

BACKGROUND Dermatofibrosarcoma protuberans (DFSP) is an invasive skin tumor traditionally associated with very high recurrence rates when treated with conventional surgery (CS). OBJECTIVE To calculate the minimum margin that would have been required to achieve complete tumor clearance with hypothetical CS. To analyze DFSP characteristics and Mohs micrographic surgery (MMS) effectiveness in treatment of this tumor. MATERIALS AND METHODS Minimum margin was calculated by measuring the largest distance from the visible edge of the tumor to the edge of the surgical defect. Tumor variables (age, sex, size, time since onset, and location) were correlated with surgical variables (number of stages and minimum margin). RESULTS We studied 222 cases of DFSP treated with MMS. A mean of 1.47 MMS stages and a mean minimum margin of 1.23 cm were required to achieve tumor clearance. Tumors on the head and neck required significantly more stages and a significantly wider margin. Tumor size was positively correlated with time to diagnosis, age, and number of MMS stages. CONCLUSION Tumors located on the head and neck have greater subclinical extension. Tumor size was also a predictor of surgical difficulty, but time to diagnosis was not.
The influence of maternal nutritional behaviour on the nutritional behaviour of children with excess body weight

Introduction Obesity is a chronic systemic metabolic disease, which is increasingly prevalent also in children. Obesity carries a risk of numerous complications. The factors that cause excessive weight gain in children are improper eating habits and maternal obesity. The role of mothers manifests mainly in influencing the food preferences of their children. Aim of the study To analyse the relationship between the selected eating habits of mothers and the eating habits of their children with excess body weight before and after dietary intervention. Material and methods: The study group consisted of 68 overweight and obese children – patients of our department. The study used the author’s questionnaire for assessing eating habits. The eating habits were assessed in children and mothers. Results After dietary intervention reduction in mean BMI-SDS of 0.80 ±0.96 (p < 0.00001) was observed in children. Before dietary education, there was a significant relationship between mothers’ correct habits and children’s habits of, e.g., eating breakfast, cereal products drinking water, and consuming milk. Despite the dietary intervention, the influence of negative mothers’ habits on the habits of their children was still observed. Conclusions The influence of selected correct and incorrect mothers’ eating habits on shaping the eating habits of their children with excess body weight before and after dietary intervention was demonstrated. Before and after dietary intervention, this concerned, e.g., the number of eaten meals and the frequency of consuming sweets and fast food. No relationship was found between mother and child in the frequency of consumption of vegetables.
ECG-Based Deep Learning and Clinical Risk Factors to Predict Atrial Fibrillation

Supplemental Digital Content is available in the text. Background: Artificial intelligence (AI)–enabled analysis of 12-lead ECGs may facilitate efficient estimation of incident atrial fibrillation (AF) risk. However, it remains unclear whether AI provides meaningful and generalizable improvement in predictive accuracy beyond clinical risk factors for AF. Methods: We trained a convolutional neural network (ECG-AI) to infer 5-year incident AF risk using 12-lead ECGs in patients receiving longitudinal primary care at Massachusetts General Hospital (MGH). We then fit 3 Cox proportional hazards models, composed of ECG-AI 5-year AF probability, CHARGE-AF clinical risk score (Cohorts for Heart and Aging in Genomic Epidemiology–Atrial Fibrillation), and terms for both ECG-AI and CHARGE-AF (CH-AI), respectively. We assessed model performance by calculating discrimination (area under the receiver operating characteristic curve) and calibration in an internal test set and 2 external test sets (Brigham and Women’s Hospital [BWH] and UK Biobank). Models were recalibrated to estimate 2-year AF risk in the UK Biobank given limited available follow-up. We used saliency mapping to identify ECG features most influential on ECG-AI risk predictions and assessed correlation between ECG-AI and CHARGE-AF linear predictors. Results: The training set comprised 45 770 individuals (age 55±17 years, 53% women, 2171 AF events) and the test sets comprised 83 162 individuals (age 59±13 years, 56% women, 2424 AF events). Area under the receiver operating characteristic curve was comparable using CHARGE-AF (MGH, 0.802 [95% CI, 0.767–0.836]; BWH, 0.752 [95% CI, 0.741–0.763]; UK Biobank, 0.732 [95% CI, 0.704–0.759]) and ECG-AI (MGH, 0.823 [95% CI, 0.790–0.856]; BWH, 0.747 [95% CI, 0.736–0.759]; UK Biobank, 0.705 [95% CI, 0.673–0.737]). Area under the receiver operating characteristic curve was highest using CH-AI (MGH, 0.838 [95% CI, 0.807 to 0.869]; BWH, 0.777 [95% CI, 0.766 to 0.788]; UK Biobank, 0.746 [95% CI, 0.716 to 0.776]). Calibration error was low using ECG-AI (MGH, 0.0212; BWH, 0.0129; UK Biobank, 0.0035) and CH-AI (MGH, 0.012; BWH, 0.0108; UK Biobank, 0.0001). In saliency analyses, the ECG P-wave had the greatest influence on AI model predictions. ECG-AI and CHARGE-AF linear predictors were correlated (Pearson r: MGH, 0.61; BWH, 0.66; UK Biobank, 0.41). Conclusions: AI-based analysis of 12-lead ECGs has similar predictive usefulness to a clinical risk factor model for incident AF and the approaches are complementary. ECG-AI may enable efficient quantification of future AF risk.
Measurement practices in hallucinations research

ABSTRACT Introduction: In several sub-fields of psychology, there has been a renewed focus on measurement practices. As far as we are aware, this has been absent in hallucinations research. Thus, we investigated (a) cross-study variation in how hallucinatory experiences are measured and (b) the reliability of measurements obtained using two tasks that are widely employed in hallucinations research. Method: In Study 1, we investigated to what extent there was variation in how the Launay-Slade Hallucination Scale (LSHS) has been used across 100 studies. In Study 2, we investigated the reliability of the measurements obtained through source monitoring and signal detection tasks, using data from four recent publications. Materials/data are available at doi: 10.17605/osf.io/d3gnk/. Results: In Study 1, we found substantial variation in how hallucinatory experiences were assessed using the LSHS and that descriptions of the LSHS were often incomplete in important ways. In Study 2, we reported a range of reliability estimates for the measurements obtained using source monitoring and signal discrimination tasks. Some measurements obtained using source monitoring tasks had unacceptably low levels of reliability. Conclusions: Our findings suggest that suboptimal measurement practices are common in hallucinations research and we suggest steps researchers could take to improve measurement practices.
Edinburgh Research Explorer Associations between hearing and cognitive abilities from childhood to middle age

Previous cross-sectional ﬁ ndings indicate that hearing and cognitive abilities are positively correlated in childhood, adulthood, and older age. We used an unusually valuable longitudinal dataset from a single-year birth cohort study, the National Child Development Study 1958, to test how hearing and cognitive abilities relate to one another across the life course from childhood to middle age. Cognitive ability was assessed with a single test of general cognitive ability at age 11 years and again with multiple tests at age 50. Hearing ability was assessed, using a pure tone audiogram, in childhood at ages 11 and 16 and again at age 44. Associations between childhood and middle-age hearing and cognitive abilities were investigated using structural equation modelling. We found that higher cognitive ability was associated with better hearing (indicated by a lower score on the hearing ability variables); this association was apparent in childhood ( r = -0.120, p <0.001) and middle age ( r = -0.208, p <0.001). There was a reciprocal relationship between hearing and cognitive abilities over time: better hearing in childhood was weakly associated with a higher cognitive ability in middle age ( β = -0.076, p = 0.001), and a higher cognitive ability in childhood was associated with better hearing in middle age ( β = -0.163, p <0.001). This latter, stronger effect was mediated by occupational and health variables in adulthood. Our results point to the discovery of a potentially life-long relationship between hearing and cognitive abilities and demonstrate how these variables may in ﬂ uence one another over time.
Structural connectome differences in pediatric mild traumatic brain and orthopedic injury

Sophisticated network‐based approaches such as structural connectomics may help to detect a biomarker of mild traumatic brain injury (mTBI) in children. This study compared the structural connectome of children with mTBI or mild orthopedic injury (OI) to that of typically developing (TD) children. Children aged 8–16.99 years with mTBI (n = 83) or OI (n = 37) were recruited from the emergency department and completed 3T diffusion MRI 2–20 days postinjury. TD children (n = 39) were recruited from the community and completed diffusion MRI. Graph theory metrics were calculated for the binarized average fractional anisotropy among 90 regions. Multivariable linear regression and linear mixed effects models were used to compare groups, with covariates age, hemisphere, and sex, correcting for multiple comparisons. The two injury groups did not differ on graph theory metrics, but both differed from TD children in global metrics (local network efficiency: TD > OI, mTBI, d = 0.49; clustering coefficient: TD < OI, mTBI, d = 0.49) and regional metrics for the fusiform gyrus (lower degree centrality and nodal efficiency: TD > OI, mTBI, d = 0.80 to 0.96; characteristic path length: TD < OI, mTBI, d = −0.75 to −0.90) and in the superior and middle orbital frontal gyrus, paracentral lobule, insula, and thalamus (clustering coefficient: TD > OI, mTBI, d = 0.66 to 0.68). Both mTBI and OI demonstrated reduced global and regional network efficiency and segregation as compared to TD children. Findings suggest a general effect of childhood injury that could reflect pre‐ and postinjury factors that can alter brain structure. An OI group provides a more conservative comparison group than TD children for structural neuroimaging research in pediatric mTBI.
Ecological correlates of the morphology of the auditory bulla in rodents: Application to the fossil record

For rodents, hearing is essential to survival. It enables predator evasion, prey detection, and conspecific recognition; it is also likely to be constrained by the physical environment. The resulting hypothetical link between tympanic bulla morphology and ecology has never been investigated across a broad array of rodent species before. Such link may enable the determination of the ecological affinities of many fossil species only known from partial skulls. In this study, we used geometric morphometrics to quantify the shape of the auditory bulla of 197 specimens representing 91 species from 17 families of extant rodents across four different locomotory modes. We used landmarks and semi‐landmarks on the ventral and lateral views of the skull to capture morphological characteristics of the bulla and external auditory meatus (EAM). Our results demonstrate an association between bullar morphology and locomotion in rodents. Bullar shape enables the correct classification of 76% of the species in our training set. Fossorial taxa, in particular, show a characteristic morphology including an asymmetric bulla with a dorsally located and laterally expanded EAM that has a small opening diameter. A phylogenetically informed flexible discriminant analysis shows a weak phylogenetic effect on tympanic morphology. There is no evidence for differences in bullar hypertrophy across locomotory categories. The application of this approach to select fossil rodents from the Oligo‐Miocene shows broad agreements with prior studies and yields new locomotory inferences for 14 fossil species, including the first proposed locomotion for members of the family Florentiamyidae. Such results call for the timing of burrowing diversification in rodents to be reevaluated.
