Analyzing the Covariance Structure of Plasma Signaling Proteins in Relation to the Diagnosis of Dementia

Calvin Guan, Rhoda Au, Alvin Ang and Ashis Gangopadhyay

Article Type: Original Research | First Published: 2024/02/12

Numerous studies have shown that individuals with dementia have exhibited activation of inflammatory pathways in their brains. Typically, these studies use traditional and well-established regression methods for data analysis. In this paper, a new approach is introduced that utilizes the analysis of the covariance structure using methods related to the principal component analysis (PCA) theory. Eleven biomarkers related to neuroinflammation were used to determine the association with the onset o...

Fitting Birth and Death Queuing Models using Maximum Likelihood Estimation with Application to COVID-19 Pandemic in Sub-Saharan Africa

Nkemnole EB and Kuti OO

Article Type: Research Article | First Published: March 03, 2023

The COVID-19 pandemic has revealed facts about deficiencies in health resource planning of some countries having relatively high case count and death toll. The virus has undergone an observed increase of cases that led to a global pandemic. Many authors have developed different models for predicting or observing the current trend of COVID-19 pandemic. In this study, fitting birth and death models using maximum likelihood estimation (MLE) method with application to COVID-19 in sub-Sahara Africa i...

Hypothyroidism: A Small Clinical Trial Will Quickly Resolve the Combination Therapy Controversy

Timothy A Welborn, AO, PhD, FRCP, FRACP, MBBS and Satvinder S Dhaliwal, PhD, MSc, BSC

Article Type: Letter | First Published: October 23, 2022

Hypothyroidism is an extremely common condition. More than 100 million prescriptions for thyroxine (T4) are processed in the USA each year. T4 is the recommended treatment for hypothyroidism. But 5-15% of patients treated to target with T4 continue to have symptoms. Some of these patients respond dramatically to the addition of triiodothyronine (T3) as first reported 20 years ago....

A New Modified Liu Ridge-Type Estimator for the Linear Regression Model: Simulation and Application

Olasunkanmi J Oladapo, Abiola T Owolabi, Janet I Idowu and Kayode Ayinde

Article Type: Original Research | First Published: July 09, 2022

Several efforts have been made to solve the multicollinearity problem, which arises from correlated regressors in the linear regression model. This is because the Ordinary Least Squares (OLS) Estimator becomes inefficient in the presence of multicollinearity....

Development of a Novel Retrospective Instrument to Gauge the General Well-being Index and Lumbar Specific Disability Index Post Intervention in Lumbar Degenerative Disease

Song Ying Chong, MBBS, Mahmoud Danaee, PhD and Dharmendra Ganesan, FRCS

Article Type: Original Article | First Published: July 04, 2022

The clinical outcome data for patients who had a particular intervention for the lumbar degenerative disease is based on changes in symptomatology. This functional data had been acquired in a prospective manner using standard tools e.g., ODI, RMQ, SF-36 etc. Such data may be lacking in many facilities of developing countries due to various reasons....

Time Based Prediction of Breast Cancer Tumor Recurrence Using Machine Learning

Siddharth Raj Gupta

Article Type: Original Article | First Published: May 06, 2022

An in-depth study using the database from GLOBOCAN, CDC, and WHO health repository highlights the lethality of breast cancer, taking thousands of lives each year. Therefore, timely prediction of cancer can help patients to consult the doctor on time. In the past various studies have successfully predicted the nature of the tumor to be benign or malignant and if the breast cancer tumor will reoccur or not. However, no time-based models have been studied previously. With the help of Machine Learni...

Triple Negative Breast Cancer Prevalence in Indian Patients over a Decade: A Systematic Review

Suvobrata Sarkar and Murtaza Akhtar

Article Type: Systematic Review and Meta-analysis | First Published: January 12, 2022

Triple Negative Breast Cancer (TNBC) is an aggressive variant of breast cancer with penurious prognosis and limited therapeutic options. This subtype is characterised with higher incidence rate among the younger women, aggressive tumour behaviour, with early local recurrence and distant metastasis leading to poor outcomes. In India, majority of prevalence data of TNBC is hospital based from patient treated at tertiary care hospitals or centres ranging from 10% to 43% which is evident from the va...
