Regressive Class Modelling for Predicting Trajectories of COVID-19 Fatalities Using Statistical and Machine Learning Models.

The COVID-19 (SARS-CoV-2 virus) pandemic has led to a substantial loss of human life worldwide by providing an unparalleled challenge to the public health system. The economic, psychological, and social disarray generated by the COVID-19 pandemic is devastating. Public health experts and epidemiologists worldwide are struggling to formulate policies on how to control this pandemic as there is no effective vaccine or treatment available which provide long-term immunity against different variants of COVID-19 and to eradicate this virus completely.

Analyzing the effect of duration on the daily new cases of COVID-19 infections and deaths using bivariate Poisson regression: a marginal conditional approach.

The whole world is devastated by the impact of the COVID-19 pandemic. The socioeconomic and other effects of COVID-19 on people are visible in all echelons of society. The main goal of countries is to stop the spreading of this pandemic by reducing the COVID-19 related new cases and deaths.

Regressive models for risk prediction of repeated multinomial outcomes: An illustration using Health and Retirement Study data.

Life expectancy is increasing in many countries and this may lead to a higher frequency of adverse health outcomes. Therefore, there is a growing demand for predicting the risk of a sequence of events based on specified factors from repeated outcomes. We proposed regressive models and a framework to predict the joint probabilities of a sequence of events for multinomial outcomes from longitudinal studies.

Effect of routine iron-folic acid supplementation among rural pregnant women living in low- and high-groundwater-iron areas in Bangladesh.

Objective: The present study investigated the risks and benefits of routine Fe-folic acid (IFA) supplementation in pregnant women living in low- and high-groundwater-Fe areas in Bangladesh.

Design: A case-controlled prospective longitudinal study design was used to compare the effect of daily Fe (60 mg) and folic acid (400 μg) supplementation for 3·5 months.

Setting: A rural community in Bangladesh.

Anemia and iron deficiency in rural Bangladeshi pregnant women living in areas of high and low iron in groundwater.

Background: Recent studies found a low rate of iron deficiency in Bangladeshi non-pregnant and non-lactating women. This was attributed to high iron concentrations in drinking water. However, there are limited data on iron deficiency among pregnant women in Bangladesh.

A generalized right truncated bivariate Poisson regression model with applications to health data.

A generalized right truncated bivariate Poisson regression model is proposed in this paper. Estimation and tests for goodness of fit and over or under dispersion are illustrated for both untruncated and right truncated bivariate Poisson regression models using marginal-conditional approach. Estimation and test procedures are illustrated for bivariate Poisson regression models with applications to Health and Retirement Study data on number of health conditions and the number of health care services utilized.

Prediction of hypertension based on the genetic analysis of longitudinal phenotypes: a comparison of different modeling approaches for the binary trait of hypertension.

For the analysis of the longitudinal hypertension family data, we focused on modeling binary traits of hypertension measured repeatedly over time. Our primary objective is to examine predictive abilities of longitudinal models for genetic associations. We first identified single-nucleotide polymorphisms (SNPs) associated with any occurrence of hypertension over the study period to set up covariates for the longitudinal analysis.

Factors influencing patient satisfaction in primary healthcare clinics in Kuwait.

Purpose: To measure the quality of health care services patient satisfaction is used as one of the most important indicators. The study aims to identify factors affecting patient's satisfaction at primary health care clinics.

Design/methodology/approach: The data was collected during January 2007 and May 2007 through a randomly-distributed questionnaire.

Determinants of antenatal morbidity: a multivariate analysis.

Objectives: The aim of this paper was to investigate the potential risk factors for developing complications and their magnitude during the antenatal period.

Methodology: The data used in this paper came from a prospective survey in rural areas of Bangladesh conducted by the Bangladesh Institute of Research for Promotion of Essential and Reproductive Health and Technologies (BIRPERHT) between November 1992 and December 1993. The differential patterns were analyzed for respondents' selected characteristics, and multivariate analysis was performed employing logistic regression and proportional hazards models for life-threatening and high-risk complications during pregnancy.

Patient demographics and disease variables correlate with distinct cytokine patterns in mitogen-stimulated peripheral blood mononuclear cells from rheumatoid arthritis patients.

There is paucity of literature on the association of peripheral blood cytokine patterns with patient demographics and disease variables in rheumatoid arthritis (RA). We test the hypothesis that there may be differences in peripheral blood levels of inflammatory cytokines in RA subjects according to various disease variables. In this case, we could identify peripheral blood cytokine markers that correlate with different disease variables.

Delivery complications and healthcare-seeking behaviour: the Bangladesh Demographic Health Survey, 1999-2000.

Maternal health services have a potentially critical role in the improvement of reproductive health. The use of health services is related to the availability, quality and cost of the services, as well as to social structure, health beliefs and the personal characteristics of the users. The present paper examined the factors that influence the use of maternal health services for some selected pregnancy-related complications (e.

Factors influencing nurses' attitudes towards the use of computerized health information systems in Kuwaiti hospitals.

Aim: This paper reports a survey of nurses' attitudes towards computerized health information systems, the characteristics that influence these attitudes and the level of nurses' skills in computer use.

Background: The use of such systems in developed countries and in some developing countries has already become a reality. However, nurses as a group of care providers have been found to resist computerization, seeing computerized health information systems as dehumanizing, confusing and uncaring.

Complications during pregnancy, delivery, and postnatal stages and place of delivery in rural Bangladesh.

The utilization of safe motherhood services including maternity care in Bangladesh is very poor. Only a very small proportion of deliveries takes place in a hospital/clinic. This study is based on data from a follow-up study on maternal morbidity in rural Bangladesh.

Statistical methods for analysis of repeated measures on maternal morbidity.

Objectives: This paper applies statistical methods to identify factors associated with pregnancy-related complications in rural Bangladesh. The results are examined in order to identify the factors that can help formulate policy for reducing pregnancy-related morbidity.

Methods: Two statistical methods are used in this study to analyse the repeated-measures data on pregnancy-related complications in rural Bangladesh.

Frequency of red blood cell alloantibody in Kuwaiti population.

Objective: The aim of this study was to analyze the alloimmunization against red blood cells (RBC) among Kuwaiti population.

Unmet need for contraception in Kuwait: issues for health care providers.

Based on a nationally representive household survey of Kuwaiti women held in 1999 (n = 1502) unmet need for contraception was analyzed in Kuwait, an oil-rich Muslim country. It was found that 9.7% currently married women had an unmet need for contraception.

A multistage model for maternal morbidity during antenatal, delivery and postpartum periods.

There is acute dearth of information regarding factors affecting complications during different stages of childbearing in Bangladesh. This study employs a multistage model that involves transitions at different stages to complications. The proposed model appears to display more meaningful explanation concerning the impact of different factors on the incidence of complications taking into account types of transitions.

Determinants of the use of maternal health services in rural Bangladesh.

Utilization of health services is a complex behavioral phenomenon. Empirical studies of preventive and curative services have often found that use of health services is related to the availability, quality and cost of services, as well as to social structure, health beliefs and personal characteristics of the users. In this paper an attempt is made to examine the factors associated with the use of maternal health care services in Bangladesh on the basis of data from a survey of maternal morbidity in Bangladesh, conducted by the Bangladesh Institute of Research for Promotion of Essential and Reproductive Health and Technologies (BIRPERHT).

Analysis of ante-partum maternal morbidity in rural Bangladesh.

This paper presents the results of a prospective study of maternal morbidity during the ante-partum period in rural areas of Bangladesh. The data came from a survey of Maternal Morbidity in Bangladesh, conducted by the Bangladesh Institute of Research for Promotion of Essential and Reproductive Health and Technologies (BIRPERHT) during the period from November 1992 to December 1993. Since then no such national level survey has been conducted in Bangladesh.

Utilisation of postnatal care in Bangladesh: evidence from a longitudinal study.

Utilisation of health services is a complex behavioural phenomenon. Empirical studies of preventive and curative services in Bangladesh have often showed that the use of health services is related to the availability, quality and cost of services, as well as to social structure, health beliefs and personal characteristics of the users. The present paper attempts to examine factors associated with the utilisation of healthcare services during the postnatal period in Bangladesh by using prospective data from a survey on maternal morbidity in Bangladesh, conducted by the Bangladesh Institute of Research for Promotion of Essential and Reproductive Health and Technologies (BIRPERT).
