Background: The optimal duration of extended endocrine therapy beyond five years after initial aromatase inhibitor-based adjuvant therapy for postmenopausal women with hormone receptor-positive breast cancer is still unknown. Therefore, we conducted a clinical trial to compare two different extended endocrine therapy durations. Methods: In the randomized phase III IDEAL trial, postmenopausal patients with hormone receptor-positive breast cancer were randomly allocated to either 2...

BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence...

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease associated with autoimmune phenomena targeting intrahepatic bile duct cells (cholangiocytes). Although PBC etiopathogenesis still remains obscure, development of anti-mitochondrial auto-antibodies against pyruvate dehydrogenase complex-E2 (PDC-E2) is a common feature. MicroRNA (miR) dysregulation occurs in liver and immune cells of PBC patients, but their functional relevance is largely unknown. We previously reported that miR-506 is overexpressed in PBC cholangiocytes and directly targets both Cl(-) /HCO3(-) anion exchanger 2 (AE2) and type III inositol 1,4,5-trisphosphate receptor (InsP3R3), leading to cholestasis...

PURPOSE OF REVIEW: To give an example of how advances in medical genetics impact a developing country and how Thailand struggle to improve medical genetics services. RECENT FINDINGS: Thailand is an example of developing country with limited resources, low geneticist to population ratio, formally decentralized even though practically centralized healthcare system and growing public interest in medical genetic technology. Nonetheless, efforts have been and still being made in regard to expanding clinical genetics services, improving access to laboratory diagnosis, increasing rare disease medication in national formulary, and training of medical genetics personnel...

PURPOSE OF REVIEW: The possibility to use vitamin D supplementation to improve muscle wasting, with particular focus on cancer cachexia, is discussed. RECENT FINDINGS: Vitamin D exerts biological actions on myogenic precursor proliferation and differentiation, impinging on muscle regeneration. However, the effects of VitD supplementation in diseases associated with muscle atrophy, such as cancer cachexia, are poorly investigated. Data obtained in experimental models of cancer cachexia show that the administration of vitamin D to tumor-bearing animals is not able to prevent or delay both muscle wasting and adipose tissue depletion, despite increased expression of muscle vitamin D receptor...

BACKGROUND: Cleft lip and palate is the most common congenital anomaly in the head and neck region. These clefts are not just a distortion of the normal appearance, but they may impose a major influence on the whole patient's life, both functionally and psychologically. Clefts affect feeding, teething, hearing, speech, and social communication. The incidence of cleft lip and palate is variable in different countries and different communities. The surgical correction of cleft lip and palate went through many evolutions, but still there is no single universal protocol of repair; however, many European countries have adopted national protocols and have established cleft centers for the management and follow up of affected population...

BACKGROUND: Among non-pharmacological therapies, musical intervention is often used for patients with Alzheimer's disease (AD) and patients presenting with chronic pain. However, their efficacy is still under debate. OBJECTIVE: Our aim was to determine the efficacy of choral singing versus painting sessions on chronic pain, mood, quality of life, and cognition in AD patients. METHODS: In this multicenter randomized controlled trial, 59 mild AD patients were randomized to a 12-week singing (SG; n = 31) or painting group (PG; n = 28)...

Ceramide levels are increased in blood and brain tissue of Alzheimer's disease (AD) patients. Since the ceramide transporter protein (CERT) is the only known protein able to mediate non-vesicular transfer of ceramide between organelle membranes, the modulation of CERT function may impact on ceramide accumulation. The competitive CERT inhibitor N-(3-hydroxy-1-hydroxymethyl-3-phenylpropyl) dodecanamide (HPA-12) interferes with ceramide trafficking. To understand the role of ceramide/CERT in AD, HPA-12 can be a useful tool to modulate ceramide trafficking...

BACKGROUND: With the advent of effective antivirals against cytomegalovirus (CMV), use of CMV hyperimmune globulin has decreased. Although antiviral prophylaxis in patients at high risk for CMV is effective, many patients still have late infection, never developing antibodies sufficient to achieve immunity. Utilizing a combination of antiviral and CMV immunoglobulin G may allow patients to achieve immunity and decrease late CMV infections. METHODS: This was a prospective randomized, open-label, pilot study comparing valganciclovir (VGCV) prophylaxis for 200 days vs VGCV for 100 days followed by CMV HIG in abdominal transplant recipients at high risk for CMV...

Pediatric drug development in the United States has grown under the current regulations made permanent by the Food and Drug Administration Safety and Innovation Act of 2012. Over 1200 pediatric studies have now been submitted to the US FDA, but there is still a high rate of failure to obtain pediatric labeling for the indication pursued. Pediatric oncology represents special problems in that the disease is most often dissimilar to any cancer found in the adult population. Therefore, the development of drug dosing in pediatric oncology patients represents a special challenge...

Inhalation of cannabis smoke is its most common use and the pulmonary complications of its use may be the single most common form of drug-induced pulmonary disease worldwide. However, the role of cannabis consumption in asthma patients and allergic clinical situations still remains controversial. To review the evidence of asthma and allergic diseases associated with the use of marijuana, we conducted a search of English, Spanish, and Portuguese medical using the search terms asthma, allergy, marijuana, marihuana, and cannabis...

Beta-N-methylamino-L-alanine (BMAA) has been demonstrated to contribute to the onset of the ALS/Parkinsonism-dementia complex (ALS/PDC) and is implicated in the progression of other neurodegenerative diseases. While the role of BMAA in these diseases is still debated, one of the suggested mechanisms involves the activation of excitatory glutamate receptors. In particular, the excitatory effects of BMAA are shown to be dependent on the presence of bicarbonate ions, which in turn forms carbamate adducts in physiological conditions...

PURPOSE OF REVIEW: The approach to systemic sclerosis (SSc) has changed over the years with an increasing focus on the very early diagnosis of the disease. The terminology identifying patients in the early phase of SSc has been significantly confusing in the last three decades. The purpose of this article is to analyze how the concept of "very early SSc" has evolved over the years, which is the role of an early diagnosis and how early treat patients. RECENT FINDINGS: Several attempts have been made over time, to create more sensitive and specific classification criteria to include the largest number of SSc patients, also in the earliest phase...

Transposons have emerged as promising vectors for gene therapy that can potentially overcome some of the limitations of commonly used viral vectors. Transposons stably integrate into the target cell genome, enabling persistent expression of therapeutic genes. Transposons have evolved from being used as basic tools in biomedical research to bona fide therapeutics. Currently, the most promising transposons for gene therapy applications are derived from Sleeping Beauty (SB) or piggyBac (PB). Stable transposition requires co-delivery of the transposon DNA with the corresponding transposase gene, mRNA, or protein...

MicroRNAs (miRNAs), as a kind of important small endogenous single-stranded non-coding RNA, play critical roles in a large number of human diseases. However, the currently known experimental verifications of the disease-miRNA associations are still rare and experimental identification is time-consuming and labor-intensive. Accordingly, identifying potential disease-related miRNAs to help people understand the pathogenesis of complex diseases has become a hot topic. In this study, we take advantage of known disease-miRNA associations combined with a large number of experimentally validated miRNA-target associations, and further develop a novel disease-miRNA-target heterogeneous network for identifying disease-related miRNAs...

Applications of bone marrow-derived mesenchymal stem cells (BM-MSCs) have been documented for diseases occur in the sports system, the central nervous system, the cardiovascular system etc. However, poor viability of donor stem cells after transplantation limits their therapeutic efficiency. Although the autophagy theory has been reported, the underlying mechanisms are still poorly understood. Isolation and culture methods of mesenchymal stem cells are currently concentrate on four ways. Overall, BM-MSCs have both important research significance and clinical application value in cell replacement therapy, gene therapy and reconstruction of tissues as well as organs especially for myocardial infarction (MI)...

Cells are powerful miniature electrophoresis chambers, at least during part of their life cycle. They die at the moment the voltage gradient over their plasma membrane, and their ability to drive a self-generated electric current carried by inorganic ions through themselves irreversibly collapses. Senescence is likely due to the progressive, multifactorial damage to the cell's electrical system. This is the essence of the "Fading electricity theory of aging" (De Loof et al., Aging Res. Rev. 2013;12:58-66)...

BACKGROUND: Direct-acting antiviral (DAA) resistance-associated substitutions (RASs) can jeopardize the effectiveness of DAAs in patients with hepatitis C virus (HCV). The selection pressure by pegylated-interferon (Peg-IFN) plus ribavirin (P/R) treatment may enhance HCV genome variation. However, whether P/R treatment alters the rate of change of RASs is still unclear. MATERIALS AND METHODS: We retrieved the genomic sequences of HCV genotype (GT) 1a patients from GenBank, which included patients naïve to P/R (pre-IFN group) and those previously treated with P/R (post-IFN group)...
