Ying Wu, Richard J Cook
With the increasing availability of large prospective disease registries, scientists studying the course of chronic conditions often have access to multiple data sources, with each source generated based on its own entry conditions. The different entry conditions of the various registries may be explicitly based on the response process of interest, in which case the statistical analysis must recognize the unique truncation schemes. Moreover, intermittent assessment of individuals in the registries can lead to interval-censored times of interest...

Kai P Law, Hua Zhang
Gestational diabetes mellitus (GDM) is a form of diabetes that is first recognised during pregnancy, with no evidence of pre-existing type 1 or type 2 diabetes. The prevalence of GDM has been rising steadily over the past few decades, coinciding with the ongoing epidemic of obesity and type 2 diabetes. Although GDM normally disappears after delivery, women who have been previously diagnosed with GDM are at a greater risk of developing gestational diabetes in subsequent pregnancies, and type 2 diabetes later in life...

Neurodegeneration, the progressive death of neurons, loss of brain function, and cognitive decline is an increasing problem for senior populations. Its causes are poorly understood and therapies are largely ineffective. Neurons, with high energy and oxygen requirements, are especially vulnerable to detrimental factors, including age-related dysregulation of biochemical pathways caused by altered expression of multiple genes. GHK (glycyl-l-histidyl-l-lysine) is a human copper-binding peptide with biological actions that appear to counter aging-associated diseases and conditions...

Hirschsprung disease (HD) in late childhood is uncommon and often undiagnosed or misdiagnosed. However, in a patient with Hirschsprung disease, of greater significance is the occurrence of life threatening enterocolitis. In its more severe form, this is associated with gross dilatation of the colon and profound toxaemia, the combination being termed toxic megacolon. Because of its relative rarity, we report a case of 10-year-old child who had a history of chronic constipation for nine years. He later developed complications and presented to the emergency department with toxic megacolon, a rare occurrence due to neglected constipation...

Multiple brain abscesses in an immunocompetent patient is a challenging clinical problem in the medical world despite advances in imaging techniques, laboratory diagnostics, surgical interventions, and antimicrobial treatment. It is a clinical entity that typically tends to occur in the presence of known predisposing factors. Clinicians seek to determine the potential risk factors responsible for the development of brain abscess because it is very crucial for management of this life-threatening condition. At times, like in our case, there are clinical situations where it is difficult to reveal any traditional risk factors...

Both long-term administration of immunosuppressive agents and chronic inflammatory conditions, such as autoimmune disease, could be risk factors for the development of cutaneous squamous cell carcinoma (cSCC). In this report, we present a case of recurrent multiple cSCC on the scalp in a patient with juvenile dermatomyositis who had been administered cyclosporine and Predonine since she was a 1-year-old infant. Interestingly, immunohistochemical staining revealed IL-17-producing cells adjacent to IL-17R-expressing atypical keratinocytes...

Myo-inositol (MI), the precursor of the second messenger phosphoinositide (PI), mediates multiple cellular events. Rat islets exhibit active transport of MI, though the mechanism involved remains elusive. Here, we report, for the first time, the expression of sodium/myo-inositol cotransporter 1 (SMIT1) in rat islets and specifically, β-cells. Genetic or pharmacological inhibition of SMIT impaired glucose-stimulated insulin secretion by INS-1E cells, probably via down-regulation of PI signaling. Additionally, we found that SMIT1 expression in INS-1E cells and isolated islets was augmented by acute high-glucose exposure and reduced in chronic hyperglycemia conditions...

Multiple sclerosis is the most common inflammatory, chronic and degenerative condition of the central nervous system, and represents the first cause of disability in young adults. In Mexico, 11 to 20 out of every 100 000 people suffer from this disease. The causes of multiple sclerosis remain unknown, but several theories have been proposed: the interaction of environmental factors, viral infectious factors and genetic and immune susceptibility of each individual patient, which induce an autoimmune response and promote neuronal/axonal degeneration...

INTRODUCTION: Neovascular age-related macular degeneration (nAMD) is a chronic eye condition that causes severe deterioration of vision and ultimately blindness. Two vascular endothelial growth factor inhibitors are approved for nAMD treatment in Europe: ranibizumab and aflibercept. The European license for ranibizumab was updated with an individualized "treat and extend" (T&E) regimen, which involves more proactive treatment based on changes in best corrected visual acuity (BCVA) and/or anatomical outcomes...

Burkholderia pseudomallei (Bp), the agent of melioidosis, causes disease ranging from acute and rapidly fatal to protracted and chronic. Bp is highly infectious by aerosol, can cause severe disease with nonspecific symptoms, and is naturally resistant to multiple antibiotics. However, no vaccine exists. Unlike many Bp strains, which exhibit random variability in traits such as colony morphology, Bp strain MSHR5848 exhibited two distinct and relatively stable colony morphologies on sheep blood agar plates: a smooth, glossy, pale yellow colony and a flat, rough, white colony...

Chronic constipation is a common, persistent condition affecting many patients worldwide, presenting significant economic burden and resulting in substantial healthcare utilization. In addition to infrequent bowel movements, the definition of constipation includes excessive straining, a sense of incomplete evacuation, failed or lengthy attempts to defecate, use of digital manoeuvres for evacuation of stool, abdominal bloating, and hard consistency of stools. After excluding secondary causes of constipation, chronic idiopathic or primary constipation can be classified as functional defecation disorder, slow-transit constipation (STC), and constipation-predominant irritable bowel syndrome (IBS-C)...

Reactivation of the hepatitis B virus (HBV) is a risk in the 350 million HBV carriers worldwide. HBV reactivation may cause hepatocellular carcinoma, cirrhosis, and fulminant hepatitis, and HBV reactivation accompanied with malignant tumor and/or chemotherapy is a critical problem for patients with chronic HBV infection. Multiple risk factors causing an immunosuppressive state can also induce HBV reactivation.We present a case of HBV reactivation during an immunosuppressive state caused by Cushing disease and physical and psychological stress after a disaster...
