A stacking ensemble deep learning approach to cancer type classification based on TCGA data

Cancer tumor classification based on morphological characteristics alone has been shown to have serious limitations. Breast, lung, colorectal, thyroid, and ovarian are the most commonly diagnosed cancers among women. Precise classification of cancers into their types is considered a vital problem for cancer diagnosis and therapy. In this paper, we proposed a stacking ensemble deep learning model b

Do women enrolled in PMTCT understand the recommendations : A case study from Kilimanjaro

Introduction: Prevention of mother-to-child transmission (PMTCT) remains a cornerstone of HIV prevention and control efforts. It is vital that the beneficiaries of PMTCT programs understand PMTCT recommendations, especially since their adherence to recommendations is key to successful PMTCT. There have been several major changes in PMTCT recommendations, and many women have encountered different r

Depression and associated factors among geriatric population in Moshi district council, Northern Tanzania

Background: Depression in the elderly population has been identified as a significant public health problem associated with adverse outcomes such as decreased quality of life, cognitive decline, and increased rates of suicide. We aimed to determine the prevalence and factors associated with depressive symptoms among geriatric population in Moshi district council, northern Tanzania. Methods: This c

Prediction of perinatal death using machine learning models : A birth registry-based cohort study in northern Tanzania

Objective We aimed to determine the key predictors of perinatal deaths using machine learning models compared with the logistic regression model. Design A secondary data analysis using the Kilimanjaro Christian Medical Centre (KCMC) Medical Birth Registry cohort from 2000 to 2015. We assessed the discriminative ability of models using the area under the receiver operating characteristics curve (AU

Internet addiction and associated factors among medical and allied health sciences students in northern Tanzania : A cross-sectional study

Background: Internet addiction is one of the fast-growing addictive behaviors and is a significant public health problem affecting a large number of people worldwide. Excessive use of the internet among university students increases their risk of internet addiction and related negative consequences. This study aimed to determine the prevalence and factors associated with internet addiction among m

Predictors of perinatal death in the presence of missing data : A birth registry-based study in northern Tanzania

Background More than five million perinatal deaths occur each year globally. Despite efforts put forward during the millennium development goals era, perinatal deaths continue to increase relative to under-five deaths, especially in low- A nd middle-income countries. This study aimed to determine predictors of perinatal death in the presence of missing data using birth registry data from Kilimanja

Factors associated with mental distress among undergraduate students in northern Tanzania

Background: Mental distress is a major public health problem which includes anxiety, depression and somatic symptoms such as sleeping problems, fatigue and headache. University students are consistently reported to have higher levels of mental distress compared to the general population. Although university students with mental distress have significantly impaired cognitive functioning, learning d

Issues and recommendations for the residual approach to quantifying cognitive resilience and reserve

Background: Cognitive reserve and resilience are terms used to explain interindividual variability in maintenance of cognitive health in response to adverse factors, such as brain pathology in the context of aging or neurodegenerative disorders. There is substantial interest in identifying tractable substrates of resilience to potentially leverage this phenomenon into intervention strategies. One

Multi-Omic Investigations of a 17-19 Translocation Links MINK1 Disruption to Autism, Epilepsy and Osteoporosis

Balanced structural variants, such as reciprocal translocations, are sometimes hard to detect with sequencing, especially when the breakpoints are located in repetitive or insufficiently mapped regions of the genome. In such cases, long-range information is required to resolve the rearrangement, identify disrupted genes and, in symptomatic carriers, pinpoint the disease-causing mechanisms. Here, w

Multi-omics analysis reveals multiple mechanisms causing Prader-Willi like syndrome in a family with a X;15 translocation

Prader-Willi syndrome (PWS; MIM# 176270) is a neurodevelopmental disorder caused by the loss of expression of paternally imprinted genes within the PWS region located on 15q11.2. It is usually caused by either maternal uniparental disomy of chromosome 15 (UPD15) or 15q11.2 recurrent deletion(s). Here, we report a healthy carrier of a balanced X;15 translocation and her two daughters, both with the

Multiple therapeutic effects of human neural stem cells derived from induced pluripotent stem cells in a rat model of post-traumatic syringomyelia

BACKGROUND: Post-traumatic syringomyelia (PTS) affects patients with chronic spinal cord injury (SCI) and is characterized by progressive deterioration of neurological symptoms. To improve surgical treatment, we studied the therapeutic effects of neuroepithelial-like stem cells (NESCs) derived from induced pluripotent stem cells (iPSCs) in a rat model of PTS. To facilitate clinical translation, we

The Cognitive Basis of the Conditional Probability Solution to the Value Problem for Reliabilism

The value problem for knowledge is the problem of explaining why knowledge is more valuable than mere true belief. The problem arises for reliabilism in particular, i.e., the externalist view that knowledge amounts to reliably acquired true belief. Goldman and Olsson argue that knowledge, in this sense, is more valuable than mere true belief due to the higher likelihood of future true beliefs (pro

Outcomes of trabecular metal total ankle replacement : a longitudinal observational cohort study of 239 consecutive cases from the Swedish Ankle Registry

Background and purpose — Information on outcomes after some modern total ankle replacement (TAR) designs is scarce. We therefore examined outcomes after trabecular metal (TM) TAR in Sweden by use of data from the national registry. Patients and methods — On December 31, 2020, 239 primary TM TARs had been reported to the Swedish Ankle Registry. We analyzed prosthesis survival probability, using exc

Postoperative Pain Management and Patient Evaluations After Five Different Surgical Procedures. A Prospective Cohort Study

Background: Sufficient pain management is a necessity and can play an important role in patients’ contentment. Aims: To investigate the instituted postoperative pain treatment, patients’ levels of pain, opioid consumption, and patient contentment, supplemented with a questionnaire based on the International Pain Outcome (IPO). Methods: This prospective observational cohort study was conducted at Z

Predicting Sensitivity to Adverse Lifestyle Risk Factors for Cardiometabolic Morbidity and Mortality

People appear to vary in their susceptibility to lifestyle risk factors for cardiometabolic disease; determining a priori who is most sensitive may help optimize the timing, design, and delivery of preventative interventions. We aimed to ascertain a person's degree of resilience or sensitivity to adverse lifestyle exposures and determine whether these classifications help predict cardiometabolic d

Orthodox Tradition and Human Sexuality

Sex is a difficult issue for contemporary Christians, but the past decade has witnessed a newfound openness regarding the topic among Eastern Orthodox Christians. Both the theological trajectory and the historical circumstances of the Orthodox Church differ radically from those of other Christian denominations that have already developed robust and creative reflections on sexuality and sexual dive

Prenatal Exposure to Locally Emitted Air Pollutants Is Associated with Birth Weight: : An Administrative Cohort Study from Southern Sweden

While prenatal exposure to ambient air pollution has been shown to be associated with reduced birth weight, there is substantial heterogeneity across studies, and few epidemiological studies have utilized source-specific exposure data. The aim of the present study was, therefore, to investigate the associations between local, source-specific exposure to fine particulate matter (PM2.5) during pregn
