Factor retention in ordered categorical variables: Benefits and costs of polychoric correlations in eigenvalue-based testing
Authors: Brandenburg Nils 
Published: May 2024

AbstractAn essential step in exploratory factor analysis is to determine the optimal number of factors. The Next Eigenvalue Sufficiency Test (NEST; Achim, 2017) is a recent proposal to determine the number of factors based on significance tests of the statistical contributions of candidate factors indicated by eigenvalues of sample correlation matrices. Previous simulation studies have shown NEST to recover the optimal number of factors in simulated datasets with high accuracy. However, these studies have focused on continuous variables. The present work addresses the performance of NEST for ordinal data. It has been debated whether factor models – and thus also the optimal number of factors – for ordinal variables should be computed for Pearson correlation matrices, which are known to underestimate correlations for ordinal datasets, or for polychoric correlation matrices, which are known to be instable. The central research question is to what extent the problems associated with Pearson correlations and polychoric correlations deteriorate NEST for ordinal datasets. Implementations of NEST tailored to ordinal datasets by utilizing polychoric correlations are proposed. In a simulation, the proposed implementations were compared to the original implementation of NEST which computes Pearson correlations even for ordinal datasets. The simulation shows that substituting polychoric correlations for Pearson correlations improves the accuracy of NEST for binary variables and large sample sizes (N = 500). However, the simulation also shows that the original implementation using Pearson correlations was the most accurate implementation for Likert-type variables with four response categories when item difficulties were homogeneous.

On trouvera ici une suite au débat qui opposa Conrad Stein à Jacques Lacan en juin 1966 dans le prolongement de mon livre Rester freudien avec Lacan . Trois concepts en furent l’enjeu : le statut de la régression dans la cure, le concept de narcissisme primaire et le statut de la parole du psychanalyste. En dépit du voile de silence maintenu par Lacan et par Stein, leur correspondance de 1971 lors de la publication de L’Enfant imaginaire ainsi que les propos tenus par Stein lors de trois journées d’étude consacrées à Lacan après sa mort découvrent le détail de deux conceptions différentes de la cure, telles qu’initiées par la lecture que chacun fit de Freud.

Les catégories de l’affect et de la représentation peuvent, doivent se confondre avant de pouvoir in fine se différencier l’une de l’autre. Ce “va, vient et revient” est le mouvement même de psyché et celui de la cure et, plus encore, celui de la cure avec ce patient. Les représentations infantiles trop violemment refoulées sont abolies au point de disparaître apparemment définitivement, ne laissant comme traces illisibles seulement quelques figures archaïques, lointaines de lignes verticales, obliques ou spiralaires avec l’affect de déréliction qui les accompagnait originairement. Il est intéressant et précieux de voir comment l’écoute analytique, les constructions silencieuses de l’analyste, l’incompréhension temporaire qu’il lui est essentiel de savoir supporter, ont permis à ce patient de faire réapparaître les images centrales de l’affect : la mère, fichu au vent sous la pluie, précédant l’apparition de la musique de la parole maternelle parlant aux animaux et débouchant sur une remémoration puissante de Charlie Chaplin avec le retour de la prééminence de la parole. Il s’agit encore, dans cet écrit, du partage d’un processus analytique, d’un travail intérieur que l’on peut désigner comme « une remémoration à deux » où analysant et analyste peuvent et doivent se confondre avant de se réinventer.

Published: May 2024

Introduction : L’objectif de cette étude était d’analyser le taux de mise en œuvre des programmes de récupération améliorée en chirurgie (RAC) selon le secteur d’hospitalisation. Méthodes : Il s’agit d’une étude longitudinale rétrospective à partir des séjours hospitaliers entre mars et décembre 2019. Nous avons étudié treize des segments d’activité les plus fréquemment inclus dans un protocole RAC. Le critère d’évaluation principal est le taux de RAC. Les résultats ont été analysés d’abord globalement puis en appariant les séjours RAC aux séjours non-RAC selon le type d’établissement, l’âge, le sexe, le mois de sortie, le niveau de sévérité, et le score de comorbidité de Charlson. Résultats : 420 031 séjours ont été pris en compte dont 78 119 ont été codés en RAC. 62 403 ont été appariés avec des séjours non-RAC. Le taux d’implémentation variait de 5 % à 30 %. Le taux de RAC était plus élevé dans le secteur privé (21,2 %) que dans le secteur public (14,4 %). Les résultats sont inversés pour certaines chirurgies principalement oncologiques. Les patients avaient un score de Charlson plus élevé dans le secteur public. Conclusions : Cette étude nationale à grande échelle permet de dresser un tableau du niveau de diffusion de la RAC en France. Malgré des différences entre secteurs, cette diffusion reste globalement insuffisante. Compte tenu des avantages démontrés de la RAC, davantage d’efforts pédagogiques sont nécessaires pour améliorer leur mise en œuvre en France.

Published: May 2024

Purpose
To determine mental health literacy (MHL) levels of older adults and the predictive factors of MHL.

Method

This cross-sectional study was conducted between October and December 2022, with 410 older adults aged ≥65 years. A Personal Information Form and the Mental Health Literacy Scale were used for data collection. Independent samples
t
test, analysis of variance, and multiple linear regression were used to analyze the data.

Results
Significant predictors of MHL in older adults were being aged 65 to 69 years, being female, being a university graduate, having an income more than expenses, receiving information from a health professional, interest in mental health, having friends or family members with mental illness, and good perception of health.

Conclusion

Older adults were found to have low levels of MHL. Mental health professionals should focus on community-based education and interventions to increase the MHL levels of older adults. [

Published: May 2024

Purpose
To explore the perspectives and experiences of mental health care workers (MHCWs) when speaking up about patient safety concerns.

Method
A qualitative study was performed at Farshchian (Sina) Hospital in Iran, involving the purposive sampling of MHCWs from three inpatient psychiatric wards. From July to October 2022, semi-structured interviews were conducted with 23 participants. Data were analyzed using conventional content analysis.

Results

Three major patient safety themes were identified: (a)
Voicing Concerns for Daily Safety
(subthemes: daily safety check-ins and speaking up to prevent patient harm); (b)
Speaking Up to Save Future Lives
(subthemes: whistleblowing, leadership, and being open to communication); and (c)
Hesitating to Speak Up
(sub-themes: ineffectiveness of raising one's voice and whispering).

Conclusion

MHCWs have various concerns about speaking up or staying silent. Failure to communicate can result in adverse events and missed opportunities to address patient safety. [

Breath-holding Spells in Pediatrics: Clinicolaboratory Findings and Cardiac Repolarization Changes
Authors: Gamal El-Din Hadeer Mahmoud , Gaber Rana Ahmed , Abo Elnour Sara I. 
Published: May 2024

Abstract

Background:
Breath-holding spells (BHS) are a benign common problem in young children. Autonomic nervous system dysregulation plays an important role in its pathogenesis. BHS may be associated with iron-deficiency anemia (IDA).

Objectives:
The objective of the study was to explore the clinicolaboratory profile of children with BHS, electrocardiography (ECG), and echocardiography (ECHO) findings.

Methods:
The study included 50 children with breath-holding spells (BHS) and 50 controls, enrolled over 16 months. Clinical evaluation involved detailed history-taking, physical examination, and growth assessment. Laboratory investigations included complete blood count, serum iron, and serum ferritin levels. Electrocardiography (ECG) recordings were analyzed for corrected QT interval (QTc) and QTc dispersion (QTcd). Echocardiography (ECHO) studies were conducted to exclude primary cardiac diseases. Ethical approval was obtained, and statistical analysis was performed using SPSS version 26.”The study included 50 children with breath-holding spells (BHS) and 50 controls, enrolled over 16 months. Clinical evaluation involved detailed history-taking, physical examination, and growth assessment. Laboratory investigations , Electrocardiography (ECG) recordings and Echocardiography (ECHO) studies were conducted and were analyzed.

Results:
The mean age of our children was 35 ± 20 months with their ages ranging from 11 to 84 months. Thirty-one children were male (62%) and 19 were female (38%). Cyanotic spells were present in 35 (70%) children, 7 (14%) children were of the pallid type, and 8 (16%) children were of the mixed type. Detailed history, laboratory tests (complete blood count, serum iron, and serum ferritin), ECG, and ECHO were done. Anemia was found in 66% of them (44% had IDA). The corrected QT interval (QTc) was 0.45 ± 0.02 s, 16% of children had prolonged QTc (>0.46 s), and QTc dispersion (QTcd) was 0.03 ± 0.02 s. We found a highly significant difference (P = 0.001) between cases and controls as regards QTc values, and no significant difference (P = 0.32) between the two groups as regards QTcd values.

Conclusions:
The cyanotic type is more common than the pallid and mixed types of BHS. IDA is a common finding in BHS. QTc is increased in children with BHS, which is a sign of cardiac repolarization changes. Therefore, the use of ECG for the diagnosis of rhythm abnormalities in these children is reasonable.
A study of mydriatic effect on intraocular pressure and anterior chamber angle morphology by anterior segment optical coherence tomography
Authors: Prabhakar Srinivasapuram Krishnacharya , Hiremath Meghana 
Published: May 2024

Context
Pharmacological mydriasis possibly is associated with intraocular pressure (IOP) rise and anterior chamber angle changes. Hence, this study is focused on pressure analysis with anterior segment optical coherence tomography measurements of angle parameters during various dilation phases.

Aims
Purpose is to investigate IOP variations during dilation phases and to discover association of anterior segment optical coherence tomography measurements.

Settings and design
Observational study.

Patients and methods
Thirty-two participants were recruited and IOP measured by rebound tonometer in pre, mid, and full pupillary dilation phases. Lens vault (LV at horizontal and vertical), angle opening distance (AOD at 500 and 750 μm) and trabecular iris space area (TISA at 500 and 750 μm) in temporal and nasal scans were quantified. Paired t test performed to establish a statistical significance P value less than or equal to 0.05.

Statistical analysis used
MS Excel.

Results
A total of 32 participants with mean age of 47.5±10.94 years consisting of 17 (53.13%) males and 15 (46.87%) females with 20 (62.5%) right and 12 (37.5%) left eyes were investigated. Mean IOP in pre, mid, and full-dilation phases were 14.86±2.87, 15.94±2.72, and 15.63±2.69 mmHg. Predilation IOP with IOP in mid and full dilation showed statistical significance (P=0.0001, 95% confidence interval 0.56–1.56) and 0.88 and 0.85 Pearson’s coefficients, respectively. IOP analysis with LV, AOD, and TISA in pre, mid, and full-dilation phases exhibited a significant difference (P<0.0001).

Conclusion
This research highlights an increase in IOP alongside a noteworthy decrease in the average LV by 30.94 μm during mid-dilation compared to the predilation phase. Likewise, the AOD at 750 μm demonstrated a significant reduction by 0.40 and 0.45 μm in temporal scans during mid and full dilation, respectively, while TISA remained unchanged.

Published: May 2024

Abstract

Aims:
This ex vivo study aimed to assess the dissolving capacity of 2.5% sodium hypochlorite using eight agitation protocols within swine pulp tissue.

Subjects and Methods:
Twelve lower first premolars were prepared and split into the fragments with a groove housing porcine dental pulp. Groups were assigned based on agitation systems: manual, passive ultrasonic, Easy Clean and XP-Endo Finisher. Two agitation time protocols were applied: One min (3 s × 20 s cycles) and 2 min (6 s × 20 s cycles). Wilcoxon Mann–Whitney U test was used to compare the groups.

Results:
Both time frames demonstrated superior results compared to manual group (P > 0.5). However, in the two min groups, no significant differences were observed among the other protocols (P < 0.5). Intriguingly, increasing cycle numbers significantly improved results within each group (P > 0.5).

Conclusion:
Extending the chemical agitation time during final irrigation enhances tissue removal, regardless of the irrigation protocol employed.
Diffuse Allergic Reaction to Patent Blue Dye for Sentinel Node Biopsy in Breast Cancer: A Case Report
Authors: Jin Ling , Yu Jyh-Cherng , Hong Zhi-Jie , Liao Guo-Shiou 
Published: May 2024

Abstract
We present the case of a 59-year-old Taiwanese female who is married and retired, and was diagnosed with invasive ductal carcinoma in her right breast at stage cT1cN0 (Stage IA). She visited us for further treatment and underwent breast-conserving surgery after communication. During the surgery in the operating room, Patent Blue V was injected to localize the sentinel lymph nodes. At the same time, the patient developed blue-colored urticaria around her whole body skin after the blue dye injection. This rare reaction alerted us to pay attention to the patient’s vital signs and prevent a severe allergic reaction, but her vital signs remained stable throughout the operation process. Although her vital signs were stable when she returned to the nursing ward, the patient required more time to recover, possibly due to her allergic predisposition.

Authors: Mohan Amitabh , Rangwala Murtuza , Chandaka Ganesh M 
Published: May 2024

Abstract

Introduction:
Local advancement flap is an important tool in the hands of reconstructive surgeons, whereas doing closure of the defect local tissue provides the best match. In this study, we describe a new technique for the closure of defects up to the size of 8 cm.

Materials and Methods:
It is a prospective intervention and observation study where we perform the candy closure technique to close the defect created after excising the skin lesion. This is an advancement flap technique where flaps are advanced and the defect is closed. This is a better technique to close the small skin defect.

Results:
In this study, we perform the candy closure technique in 43 patients without any flap loss or any major complication. The scar quality was fair to good and it was acceptable to the patient. The defect was closed primarily so the requirement of dressing was alleviated and the patient could return to work early.

Conclusion:
The candy closure technique is a safe and effective advancement flap for the closure of defects using surrounding skin. The technique can be used to close small defects where redundant skin is amiable in the surroundings.
Novel use of intraprocedural ibutilide during atrioventricular nodal reentrant tachycardia ablation
Authors: Bera Debabrata , Banerjee Arnab , Bhattacharya Kuntal , Majumder Suchit 
Published: May 2024

Abstract
Atrial fibrillation (AF) is known to occur during electrophysiology studies during the induction of supraventricular tachycardia, especially with isoprenaline. If AF is sustained ablation becomes challenging. DC cardioversion (DCCV) is preferred as medications like amiodarone alters subsequent analysis. We report a 45-year-old female with atrioventricular nodal reentrant tachycardia (AVNRT) (induced with isoprenaline), who developed spontaneous AF, which recurred several times (despite successful DCCV). It was finally controlled with ibutilide. She was taken up after 1 h when AVNRT could be reinduced without any occurrence of AF. The AV nodal property was altered minimally. Radiofrequency ablation could be successfully performed. This is the first report of ibutilide-aided AVNRT ablation, which appears feasible and does not affect inducibility.

Published: May 2024

Abstract

Background:
Several investigations suggested correlation between microscopic colitis (MC) and celiac disease (CD). This study aimed to examine this relationship using large-sized, population-based data with adequate control for confounding factors.

Methods:
This study employed the National Inpatient Sample (NIS) database over 4 years (2016–2019). Patients with/without MC in the presence/absence of CD were identified through ICD-10 codes. Univariate and multi-variate analyses involving odds ratios (OR) and 95% confidence intervals (CI) were performed.

Results:
Overall, 26,836,118 patients were analyzed. Of whom, 6,836 patients had MC (n = 179 with CD and n = 6,657 without CD). The mean hospital stay was not significantly different between both groups (5.42 ± 5.44 days vs. 4.95 ± 4.66 days, P = 0.202). The univariate analysis revealed a significant association between MC and CD (OR = 22.69, 95% [19.55, 26.33], P < 0.0001). In the multi-variate analysis, which adjusted for potential confounders including age, race, hospital region, hospital teaching status, ZIP income, smoking status, alcohol overuse, hypertension, diabetes mellitus, lipidemia-related disorders, non-steroidal anti-inflammatory drug use, and selected auto-immune diseases, the association remained significant (OR = 15.71, 95% CI [13.52, 18.25], P < 0.0001). Moreover, in patients with MC, the presence of CD emerged as a significant, independent variable of in-hospital mortality in univariate (OR = 2.87, 95% [1.14, 7.21], P = 0.025) and multi-variate (OR = 3.37, 95% CI [1.32, 8.60], P = 0.011) analyses.

Conclusion:
This study establishes a probable link between MC and CD, backed by both univariate and multi-variate analyses, while also identifying CD as an independent risk factor for increased mortality among MC patients. These findings need to be validated in real-world clinical studies.
Antifungal Susceptibility Pattern of Fungi Isolated from Patients with Otomycosis Attending a Tertiary Health Care Institution in Sokoto, Nigeria
Authors: Yabo Umar Sufiyanu , Robert Iseh Kufre , Mohammed Yahaya 
Published: May 2024

Abstract

Background:
Antifungal therapy is an important component of patient management for acute and chronic mycoses. However, treatment choices are restricted because of the scanty number of antifungal drug classes. Medical treatment of otomycosis is further compromised by the emergence of antifungal drug resistance, and these limits available drug classes as treatment options. Once considered a rare occurrence, antifungal drug resistance is on the rise in many high-risk medical centers. Most concerning is the evolution of multidrug-resistant organisms refractory to several different classes of antifungal agents, especially among common Candida species.

Aim:
This study seeks to identify the fungal species implicated in otomycosis among patients attending a tertiary health-care institution in Sokoto, Nigeria and determine its susceptibility pattern using commonly used antifungal agents.

Methods:
A descriptive, cross-sectional, hospital-based study was conducted on 100 patients with otitis externa. The ear discharge specimens were collected and analyzed using the standard microbial techniques. The antibiotic susceptibility profiles were determined for 12 different antifungal by the standard disk diffusion method. Data were analyzed using the SPSS software version 25 and the P < 0.05 was considered as statistically significant.

Results:
One hundred and twenty-four external ear discharge samples were collected from either right ear, left ear, or both ears (some patients has unilateral while others have bilateral disease and those with bilateral disease, samples were taken from the two ears). Aspergillus
niger 30 (40.0%) was the most commonly isolated fungi in this study, followed by Candida spp. 25 (33.3%), Aspergillus
fumigatus 5 (6.7%), Mucor 5 (6.7%), Penicillum 4 (5.3%), Aspergillus
flavus 3 (4.0%), and Rhizopus 3 (4.0%) %). The isolated fungi were tested for antifungal sensitivity to 6 antifungal discs. A. niger shows good susceptibility to clotrimazole (100%), nystatin (90%), and fluconazole (83.3%) but was resistant to griseofulvin, terbinafine, and ketoconazole. A. flavus and A. fumigatus also show good sensitivity to clotrimazole, nystatin, and fluconazole. Candida
albicans was only susceptible to clotrimazole but resistant to other tested antifungal disc. Rhizopus and Penicillum species showed 100.0% sensitivity to clotrimazole but also resistant to other tested antifungal discs.

Conclusions:
This study revealed that Aspergillus and Candida species were the most common fungal pathogens causing otomycosis. A. niger is the predominant fungal isolate. Molds isolates showed good susceptibility to clotrimazole, while highest resistance was to terbinafine and ketoconazole. Yeasts isolates showed highest susceptibility to clotrimazole and highest resistance to nystatin and fluconazole.
