Abstract

Objective
To develop models for prediction of the onset of specific diseases in cats using pet insurance data and to evaluate their predictive performance.

Methods
Agria Pet Insurance data from almost 550,000 cats (2011 to 2016) were analyzed and used to train predictive models for periodontal disease and skin tumors using breed, sex, and insurance claim history. Random downsampling and 1:1 matching by age, insurance duration, and time at risk balanced the dataset. Variables were then further processed, with random forest and conditional logistic regression used for analysis. Model accuracy was assessed through leave-one-out cross-validation, while variable importance plots, partial dependence plots, and coefficients were used for model interpretation.

Results
Model accuracy ranged from 81.9% to 88.2% (P < .01, baseline 50%). Key predictors included prior insurance claims for “digestive,” “whole body symptom,” “skin,” and “injury conditions,” which may be nonspecific and predictive of various diseases. Maine Coon, Siamese, and Burmese cats were associated with periodontal disease–positive predictions, while domestic cats were linked with negative predictions. For skin tumors, Norwegian Forest Cats, Devon Rex and Sphynx cats, and Maine Coon cats were associated with positive predictions, whereas Birman and domestic cats were linked with negative predictions.

Conclusions
This study presents a method of machine learning predictive analysis on pet insurance data, although more comprehensive medical information and approaches accounting for data characteristics may be necessary to develop clearer predictors.

Clinical Relevance
To prevent or detect these conditions early, veterinarians can use the breed risk results to guide clients, especially those with high-risk breeds, by offering early advice on lifestyle and monitoring.

This paper explores the innovative direction control of rotating detonation waves in rotating detonation engines (RDEs) by adjusting the ignition location and employing helical combustors with a sinusoidal cross section. In our experimental setup, we conducted 25 combustion tests using two distinct combustor geometries, each featuring different helical profile directions. The following conclusion drawn from the results: when the ignition was positioned 30.6–46.0 mm from the inlet, the detonation wave direction was invariably influenced by the helical direction. This correlation was statistically significant, with an occurrence probability (assuming a random direction probability of 0.5) being [Formula: see text], far exceeding the 0.05 significance level. Furthermore, the helical combustors generated a measurable torque due to the pressure differentials created by shock waves within the combustor. This torque, recorded between [Formula: see text] at a mass flow rate of 28.5–29.0 g/s, indicates the potential of power extraction from the combustor. Notably, the torque direction was also controllable via the helical direction. This study presents a significant advancement in propulsion technology, demonstrating a novel method to control detonation wave direction and torque generation in RDEs through helical combustor design, paving the way for more efficient and controllable propulsion systems.

MISSÃO ENTRE OS NONES: O DESAFIO DA MISSÃO PÓS-MODERNA
Authors: Rodrigues Chaves Jolivê 
Published: February 2025

O crescimento daqueles que se declaram Nones, ou pessoas sem filiação religiosa, tem sido continuamente superior ao da população em geral em várias culturas. Embora uma minoria no grupo se diga ateia ou agnóstica, a grande massa afirma acreditar em Deus, mas rejeita as instituições religiosas. Assim, como cristãos e discípulos de Jesus, precisamos notar a onda cultural da mudança contemporânea como uma das oportunidades mais significativas para alcançar os Nones para Cristo. Recomenda-se uma ação intencional e planejada da igreja para promover a missão com o grupo. Tal projeto pode envolver educação teológica, agências missionárias e treinamento em abordagens práticas, entre outros elementos.
Neuro-cardiovascular correlates of controlled slow yogic breathing: A pilot study
Authors: Kharya Chhaya , Bhagat Om Lata , Deepak K. K. 
Published: February 2025

Objectives:
We assessed the frontal cerebral hemodynamic alterations and neuro-cardiovascular interactions during alternate nostril breathing (ANB), a slow yogic breathing manoeuvre.

Material and Methods:
Five healthy male volunteers (age 30 ± 3.8 years) practised ANB for 5 min at five breaths per minute with the timing ratio (seconds) of 4:2:4:2 (inspiration: Pause: Expiration: Pause). We recorded 16 channels of functional near-infrared spectroscopy at the prefrontal cortex (PFC) region of the brain, electrocardiography, beat-to-beat arterial blood pressure (BP), respiratory movements and end-tidal carbon dioxide (ETCO2) for 5 min each: Pre (T0), during (T1) and post-ANB (T2). ETCO2, oxy-haemoglobin (oxy-Hb), deoxy-haemoglobin (deoxy-Hb), total haemoglobin (HbT) concentrations and time domain parameters of heart rate variability (HRV), BP variability (BPV) and baroreflex sensitivity (BRS) were calculated.

Results:
In comparison to T0, the oxy-Hb and time domain parameters of HRV and BPV at the left lower region of the PFC were significantly increased at T1. Up-BRS-SBP showed a trend of enhancement during the manoeuvre. A significant optically measured HbT concentration with a corresponding decrease in deoxy-Hb was observed at T1.

Conclusion:
Optically measured Oxy-Hb and HbT increased gradually with the increased practice of ANB, with a simultaneous decrease in deoxy-Hb suggesting a cerebral activation during ANB that may be predominantly in ventromedial PFC. Both baroreflex and mechanical mechanisms appear responsible for the improved neurovascular coupling. Slow yogic breathing may have beneficial effects in disorders that involve cerebral hypoactivation.

Background and Objective
Advanced HIV disease (AHD), defined by the World Health Organization (WHO) as a CD4 count of fewer than 200 cells/mm3 or WHO stage 3 or 4, remains a significant contributor to AIDS-related mortality despite global antiretroviral therapy (ART) scale-up. This study aimed to determine the prevalence and identify the determinants of AHD among newly diagnosed persons living with HIV in Abia State, Nigeria.

Methods
This was a retrospective chart review that analyzed data from patients newly enrolled in the United States centers for disease control and prevention (CDC) human immunodeficiency virus (HIV) ART program in Abia State between October 2021 and September 2023. Data were collected using a proforma designed to capture socio-demographic and clinical variables, including age, gender, residence, marital status, education level, and co-morbidities. Descriptive statistics was conducted to analyze the demographic and clinical characteristics of the participants, while logistic regression was conducted to assess the determinants of advanced HIV disease among ART-naive individuals newly diagnosed with HIV.

Results
The prevalence of AHD among the study population was 10.7%. The odds of AHD were significantly lower among individuals aged 26–35 years (aOR = 0.587) and 36–45 years (aOR = 0.638) compared to other age groups. Rural residence was associated with a lower prevalence of AHD (8.6%) compared to urban (13.9%) and semi-urban (12.2%) areas. Individuals with tertiary education (aOR = 0.625) and those employed (aOR = 0.503) showed significantly reduced odds of AHD. Persons identified through outreach testing were associated with a lower prevalence of AHD (2.9%) compared to outpatient department testing (40.2%).

Conclusion and Implications for Translation
The study supports targeted community testing to reduce AHD prevalence among persons living with HIV. Expanding outreach programs to urban areas and supporting individuals with lower socioeconomic status are critical. Addressing social determinants of health, particularly education and employment, alongside early ART initiation, can mitigate the progression to advanced disease.
IMPACT OF ZN-DOPPED ON SNEDDS/ZNXFE3-XO4 FORMULATION ON THEIR CRYSTAL STRUCTURE AND ANTIOXIDANT PERFORMANCE

Published: February 2025

Self-Nano-Emulsifying Drug Delivery System (SNEDDS)/ZnxFe3-xO4 has been successfully formulated through the synthesis of ZnxFe3-xO4 by the coprecipitation method and SNEDDS/ZnxFe3-xO4 by the sonication method. This study is focused on the effect of Zn doping on the crystal structure and antioxidant performance of ZnxFe3-xO4 nanoparticles. ZnxFe3-xO4 samples were characterized using FTIR and XRD to determine the functional groups and structure of the sample, respectively. SNEDDS/ZnxFe3-xO4 samples were characterized using FTIR and Antioxidants with the DPPH method to determine the functional groups and antioxidants in the sample, respectively. The FTIR characterization results of the ZnxFe3-xO4 sample showed the emergence of Zn-O and Fe-O functional groups in the wave number range of 825-869 cm-1 and 560-594 cm-1, respectively. This indicates that Zn2+ doping was successfully synthesized and shifted the Fe3+ ion. The IR spectrum also shows that the higher the concentration of Zn2+ ions, the more significant the change in absorption intensity, indicating that more molecules absorb light at wave numbers of 825-869 cm-1. The XRD characterization results show that the ZnxFe3-xO4 nanoparticle structure is an inverse cubic spinel occupying the Fd3m crystal group. Based on the analysis of XRD data, the higher the concentration of Zn2+ doping, the smaller the size of the ZnxFe3-xO4 nanoparticles produced. The diffraction peak of the sample on the 311 plane shifts towards a smaller angle due to the effectiveness of Zn2+ ion doping, shifting the Fe3+ ion because the radius of the Zn2+ ion is larger than the Fe3+ one. The antioxidant performance analysis of SNEDDS/ZnxFe3-xO4 showed inhibition potential ranging from 11% to 15%, increasing with higher Zn²⁺ concentrations.
