Background
Respiratory distress syndrome (RDS) is a disease that commonly affects premature infants whose lungs are not fully developed. RDS results from a lack of surfactant in the lungs. The more premature the infant is, the greater is the likelihood of having RDS. However, even though not all premature infants have RDS, preemptive treatment with artificial pulmonary surfactant is administered in most cases.

Objective
We aimed to develop an artificial intelligence model to predict RDS in premature infants to avoid unnecessary treatment.

Methods
In this study, 13,087 very low birth weight infants who were newborns weighing less than 1500 grams were assessed in 76 hospitals of the Korean Neonatal Network. To predict RDS in very low birth weight infants, we used basic infant information, maternity history, pregnancy/birth process, family history, resuscitation procedure, and test results at birth such as blood gas analysis and Apgar score. The prediction performances of 7 different machine learning models were compared, and a 5-layer deep neural network was proposed in order to enhance the prediction performance from the selected features. An ensemble approach combining multiple models from the 5-fold cross-validation was subsequently developed.

Results
Our proposed ensemble 5-layer deep neural network consisting of the top 20 features provided high sensitivity (83.03%), specificity (87.50%), accuracy (84.07%), balanced accuracy (85.26%), and area under the curve (0.9187). Based on the model that we developed, a public web application that enables easy access for the prediction of RDS in premature infants was deployed.

Conclusions
Our artificial intelligence model may be useful for preparations for neonatal resuscitation, particularly in cases involving the delivery of very low birth weight infants, as it can aid in predicting the likelihood of RDS and inform decisions regarding the administration of surfactant.
Teledermatology During Military Conflicts (Preprint)
Authors: Popovych Hanna 
Published: June 2023

BACKGROUND

Telehealth, in particular teledermatology, has become an accepted way to offer necessary consultations and follow-ups, and, most importantly, to triage patients for medical intervention based on urgency.

OBJECTIVE

The objective of our study was to assess the success of a teledermatology initiative for the civilian population during a military conflict.

METHODS

Over 10 months (March 2022 to December 2022), 320 patients were consulted using: (1) store and forward teledermatology, which involves transferring images and clinical information to the dermatologist for review asynchronously; and (2) live interactive teledermatology, usually video conferencing, which allows real-time interaction between the doctor and the patient. The entire project was implemented by dermatologists based in and sponsored by the Euroderm Clinic located in Kiev, Ukraine.

RESULTS

A total of 320 patients participated. Of the civilian population consulted and managed by dermatologists via the telehealth initiative, the majority of patients (n=208, 65%) were female (mean age 37 years). Males accounted for 35% (n=112) of the sample (mean age 59 years). There were 80 consults involving pediatric patients aged 1 to 16 years, which comprised 25% of all consultations. Preliminary analysis showed that 70% (n=224) of patients experienced an acute exacerbation of chronic skin diseases and skin infections (psoriasis: n=80, 25%; eczema: n=48, 15%; seborrheic dermatitis: n=16, 5%; skin infections: n=32, 10%; skin fungal infections: n=26, 8%; acne: n=22, 7%); 20% (n=64) had skin neoplasms, including benign and malignant ones (melanoma: n=6, 2%; seborrheic keratoma: n=13, 4%; nevus: n=32, 10%; basal cell carcinoma: n=10, 3%; squamous cell carcinoma: n=3, 1%); and 10% (n=32) had skin alterations due to trauma, burns, and postsurgical treatment.

CONCLUSIONS

Teledermatology aims to provide systematic dermatological services to the most vulnerable people—women, children, and older adults—during military conflicts. According to our study, the majority of diagnoses made using teledermatology were confirmed (n=288, 90%) after an in-person examination. The correct diagnosis was hampered by factors such as poor image quality and periodic lack of internet connection.

Hydroxyapatite (Ca10(PO4)6(OH)2, HAp) is a calcium phosphate-based biomaterial that is widely used in bone implants due to its similarity in composition with the constituent elements of bone. However, HAp still has poor mechanical properties, so research was carried out to improve the mechanical properties such as reduced brittleness, less fracture resistance, and a denser structure of HAp by synthesizing composites with PEG. This study used PEG as a filler and HAp as a matrix. HAp was synthesized from blood clam shells (Anadara granosa) using the sol-gel method. HAp-PEG composite was synthesized using the in-situ method with various HAp concentrations of 40, 50, 60, 70, and 80%. FTIR characterization showed the presence of functional groups PO43− and CO23−, which indicated the presence of HAp. Analysis of the XRD pattern showed a crystal size of 24.194 nm. SEM-EDX showed the needle-shaped HAp-PEG composite HAp crystal morphology and obtained a Ca/P ratio of 1.87. Analysis of DTA results showed a weight loss of 65.72% in the composite at a temperature > 200 °C. A degradation test was also carried out to see the percentage of the HAp-PEG composite to be degraded, and the optimum degraded composite with increasing days had a concentration of 70%.

In the current endeavor, a new Schiff base of 14,15,34,35-tetrahydro-11H,31H-4,8-diaza-1,3(3,4)-ditriazola-2,6(1,4)-dibenzenacyclooctaphane-4,7-dien-15,35-dithione was synthesized. The new symmetrical Schiff base (Q) was employed as a ligand to produce new complexes comprising Co(II), Ni(II), Cu(II), Pd(II), and Pt(II) metal-ions at a ratio of 2:1 (Metal:ligand). There have been new ligands and their complexes validated by (FTIR), (UV-visible), 1H-NMR, 13C-NMR, CHNS, and FAA spectroscopy, Thermogravimetric analysis (TG), Molar conductivity, and Magnetic susceptibility. The photostabilization technique to enhance the polymer was also used. The ligand Q and its complexes were mixed in 0.5% w/w of polyvinyl chloride in tetrahydrofuran (THF). The photo stabilization of polymer films was studied at 25 °C under irradiation of light λ 380–250 nm with intensity of 7.75 × 10−9 ein dm−3 s−1. The photostabilization activity of these compounds was determined by monitoring the hydroxyl, carbonyl, and polyene indexes, weight loss method with irradiation time. The ICO, IPO and IOH index values increased with irradiation time, this increase depends on the type of additives. The surface morphology for these films was studied during irradiation time. This project is highly intriguing for the ecosystem in regards to the decrease in the consumption of plastic.

<p><strong>Objective:</strong> Evidence of an increased dementia risk with insulin use in type 2 diabetes (T2DM) is weakened by confounding by indication and disease severity. Herein we reassess this association, while accounting for confounding through design and analysis. </p>
<p><strong>Research Design and</strong> <strong>Methods:</strong> Using administrative healthcare data from British Columbia, Canada we identified patients diagnosed with T2DM in 1998-2016. To adjust for confounding by diabetes severity through design, we compared new users of insulin to new users of a non-insulin class, both from a restricted cohort of those who previously received two non-insulin antihyperglycemic classes. We further adjusted for confounding using: (1) conventional multivariable adjustment and (2) inverse probability of treatment weighting (IPTW) based on the high-dimensional propensity score algorithm. The hazard ratio [HR] (95% confidence interval [CI]) of dementia was estimated using cause-specific hazards models with death as a competing risk.</p>
<p><strong>Results:</strong> The analytical comparative cohort included 7,863 insulin vs 25,230 non-insulin users. At baseline, insulin users were more likely to have worse health indicators. A total of 78 dementia events occurred over a median (IQR) follow-up of 3.9 (5.9) years among insulin users and 179 events occurred over 4.6 (4.4) years among non-insulin users. The HR (95% CI) of dementia for insulin use vs non-insulin use was 1.68 (1.29-2.20) before adjustment and 1.39 (1.05-1.86) after multivariable adjustment, which was further attenuated to 1.14 (0.81-1.60) after IPTW weighting. </p>
<p><strong>Conclusions:</strong> Among persons with T2DM previously exposed to two non-insulin antihyperglycemic medications, no significant association was observed between insulin use and all-cause dementia. </p>

Liturgical Renewal in Contemporary Orthodox Thought in Romania: A Preliminary Assessment
Authors: Qaramah Mihail K. 
Published: June 2023

Abstract
The Romanian Orthodox Patriarchate’s liturgical renewal movement has a spontaneous character, but without a well-defined agenda. This paper examines some of the reflections from renowned Romanian theologians about the liturgical renewal in the Orthodox Church and explores how they define the notion of liturgical reform, how they perceive the idea of change in worship, and what a liturgical renewal might look like. Moreover, it examines some concrete reforms that have already been put into practice, but without specific authorization from the Romanian Church hierarchy. The purpose of this approach is to find a starting point for an official synodal and academic debate on the possibility to implement a systematic liturgical reform at an institutional level.**

Introduction. Survival rates and treatment algorithms for patients with bladder cancer (BC) depend on the depth of tumor invasion, in particular on the presence of the bladder muscle layer invasion and extraorganic spread. To assess the depth of bladder invasion, the VI-RADS system was developed in 2018, which is based on multiparametric MRI (mpMRI). According to published studies on the VI-RADS effectiveness, there is a high diagnostic accuracy for identifying formations with probable invasion into the muscle layer. The data on BC extraorganic spread are limited and the issue of assessing the sensitivity and specificity of this system requires further study.Aim of the study. To evaluate the diagnostic performance of mpMRI using the VI-RADS system in detecting muscle invasion and BC extraorganic growth.Materials and methods. A prospective study was conducted in the clinics of the National Medical Research Radiological Centre and included 75 patients aged 19 to 85 years, of which 39 (52%) had been newly diagnosed with BC, 36 (48%) had a relapse or continuous tumor growth. All patients underwent pelvic organs mpMRI on a tomograph with a magnetic field induction of 1.5T, followed by transurethral resection (TUR), TUR-biopsy of the bladder or cystectomy no later than 6 weeks after scanning.. The description of the bladder tumor included its measurements, localization and VI-RADS scale assessment. The data obtained by mpMRI were compared with the results of the morphological study using statistical analysis.Results. According to the results of the study, the overall VI-RADS scale sensitivity for categories above 3 (the presence of muscle invasion is equivocal) was 95.15% [90.11%; 99.95%], above 4 (muscle invasion is likely) – 92.59% [82.11%; 97.94%], specificity was determined at the level of 47.62% [25.71%; 70.22%] and 80.95% [58.09%; 94.55%] respectively. When assessing extraorganic spread in 30 patients, the sensitivity was 83.33% [62.62%; 95.26%], specificity – 83.33% [35.88%; 99.58%]. The accuracy and positive predictive value also had high levels from 80 to 95%, in contrast to the negative predictive value (55.56%).Conclusion. The scale for BC invasion depth assessing VI-RADS is characterized by high rates of sensitivity, specificity and accuracy, in particular when used in determining extraorganic spread.

Assessment of the odontoclastic activity in extracted deciduous teeth with and without dental caries
Authors: Priya S. Viswa , Duraisamy Vinola , Sekar Balakrishnan 
Published: June 2023

Objectives:
The aim of the study is to assess the odontoclasts and inflammatory cells in extracted deciduous teeth, with and without dental caries, and thereby evaluate the possibility of decreased rate of resorption/delay in exfoliation due to alteration in cell count of odontoclasts.

Material and Methods:
Twenty extracted deciduous teeth (10 with dental caries and 10 without dental caries) were collected, prepared, sectioned, and stained to study under a light microscope with a magnification of ×400. Histological analysis was done to assess the number, shape, and nature of odontoclasts and inflammatory cells.

Results:
The findings showed that the odontoclastic activity is more in non-carious deciduous teeth than in carious deciduous teeth which was statistically significant (P < 0.05). Findings also indicate the predominance of inflammatory cells and evident hyperemia in carious deciduous teeth which was highly significant.

Conclusion:
Odontoclast number and activity are predominant in non-carious teeth whereas there is a clear dominance of inflammatory cells in the carious specimen over the non-carious specimen which establishes that dental caries in deciduous teeth may influence the normal physiologic resorption at the cellular level with reduced odontoclast activity, reducing the rate of resorption and delaying exfoliation.

Clinical Significance:
This study supports the fact of delayed exfoliation/shedding in carious deciduous teeth.
