Low-value care: antipsychotic medication use among community-dwelling medicare beneficiaries with Alzheimer's disease and related dementias and without severe mental illness.

Antipsychotic medication use among elderly with Alzheimer's disease and related dementias (ADRD) and without severe mental illness is considered as low-value care. Our objective was to assess the factors associated with this inappropriate use of antipsychotic medications among community-dwelling Medicare beneficiaries with ADRD and without severe mental illness.

Evidence for functional interactions between the placenta and brain in pregnant mice.

The placenta plays a pivotal role in the development of the fetal brain and also influences maternal brain function, but our understanding of communication between the placenta and brain remains limited. Using a gene expression and network analysis approach, we provide evidence that the placenta transcriptome is tightly interconnected with the maternal brain and fetal brain in d 15 pregnant C57BL/...

EEG of patients in coma after traumatic brain injury reflects physical parameters of auditory stimulation but not its emotional content.

We aimed to investigate the origin of EEG response of patients in coma and after moderate TBI to emotional stimulation, whether they distinguish emotional content or only react to the physical features of an audio signal.

Uterine Cancer Incidence and Mortality - United States, 1999-2016.

Uterine cancer is one of the few cancers with increasing incidence and mortality in the United States, reflecting, in part, increases in the prevalence of overweight and obesity since the 1980s (1). It is the fourth most common cancer diagnosed and the seventh most common cause of cancer death among U.S. women (1). To assess recent trends in uterine cancer incidence and mortality by race and ethni...

Pain could negatively affect school grades - Swedish middle school students with low school grades most affected.

Recurrent headache, abdominal and musculoskeletal pain are common in adolescents and it is therefore important to understand their impact on the transitional period from childhood to adulthood. However, studies of the prevalence over time and implications on educational outcomes are still limited, especially regarding multiple pain symptoms. The present study material consists of questionnaire sur...

Effects of cold on murine brain mitochondrial function.

Therapeutic hypothermia is a strategy that reduces metabolic rate and brain damage during clinically-relevant hypoxic events. Mitochondrial respiration is compromised by hypoxia, with deleterious consequences for the mammalian brain; however, little is known about the effects of reduced temperature on mitochondrial metabolism. Therefore, we examined how mitochondrial function is impacted by temper...

Comparison of brain magnetic resonance imaging between myotonic dystrophy type 1 and cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.

Anterior temporal lobe hyperintensities detected by brain MRI are a recognized imaging hallmark of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Because similar findings may be present in patients with myotonic dystrophy type 1 (DM1), the brain MRI in these two diseases is often misinterpreted. We compared the MRI findings between the two ent...

Application of the Communication Complexity Scale in Peer and Adult Assessment Contexts for Preschoolers With Autism Spectrum Disorders.

The purpose of this study was to measure changes in communication of preschoolers with autism using the Communication Complexity Scale (CCS; Brady et al., 2012) and to examine the utility of the CCS in measuring pretreatment and posttreatment changes within peer and adult assessment contexts.

Visual inspection for diagnosing cutaneous melanoma in adults.

Melanoma has one of the fastest rising incidence rates of any cancer. It accounts for a small percentage of skin cancer cases but is responsible for the majority of skin cancer deaths. History-taking and visual inspection of a suspicious lesion by a clinician is usually the first in a series of 'tests' to diagnose skin cancer. Establishing the accuracy of visual inspection alone is critical to und...

Amyloid-degrading enzymes in Alzheimer´s disease: from molecules to genetic therapy

Alzheimer’s disease (AD) is the main form of dementia in elderly population worldwide. By 2010 it was estimated that 35.6 million of people were living with this disease, and it was projected that this figure will triple by the year 2050. According to amyloid hypothesis, production and aggregation of amyloid beta (A-beta) peptide is the initial step in AD development. A-beta peptide is generated...

Whole-Brain Functional Ultrasound Imaging Reveals Brain Modules for Visuomotor Integration.

Large numbers of brain regions are active during behaviors. A high-resolution, brain-wide activity map could identify brain regions involved in specific behaviors. We have developed functional ultrasound imaging to record whole-brain activity in behaving mice at a resolution of ∼100 μm. We detected 87 active brain regions during visual stimulation that evoked the optokinetic reflex, a visuomot...

MicroRNA-19a regulates the proliferation, migration and invasion of human gastric cancer cells by targeting CUL5.

Gastric cancer is one of the prevalent types of cancers and despite improvements in its treatment, the overall survival is still far from descent. The dearth of efficient biomarkers, chemotherapeutic agents and therapeutic targets form a major hurdle in the treatment of the gastric cancer. Accumulating evidences suggest that MicroRNAs (miRs) may prove important therapeutic targets/agents for the m...

CNB-001, a pleiotropic drug is efficacious in embolized agyrencephalic New Zealand white rabbits and ischemic gyrencephalic cynomolgus monkeys.

Ischemic stroke is an acute neurodegenerative disease that is extremely devastating to patients, their families and society. Stroke is inadequately treated even with endovascular procedures and reperfusion therapy. Using an extensive translational screening process, we have developed a pleiotropic cytoprotective agent with the potential to positively impact a large population of brain ischemia pat...

Traces of Statistical Learning in the Brain's Functional Connectivity after Artificial Language Exposure.

Our environment is full of statistical regularities, and we are attuned to learn about these regularities by employing Statistical Learning (SL), a domain-general ability that enables the implicit detection of probabilistic regularities in our surrounding environment. The role of brain connectivity on SL has been previously explored, highlighting the relevance of structural and functional connecti...

Trends of skin cancer mortality after transplantation in the United States: 1987 to 2013.

- -Organ transplant recipients are at high risk of skin cancer mortality.-This study defines population-based mortality from skin cancer posttransplantation and identifies recipients at increased risk of skin cancer mortality.-These findings can guide dermatologists in adopting skin cancerescreening protocols specific to the identified high- risk categories.

Targeting indoleamine-2,3-dioxygenase in cancer: Scientific rationale and clinical evidence.

Immunotherapy through immune checkpoint blockers (ICBs) is quickly transforming cancer treatment by improving patients' outcomes. However, innate and acquired resistance to ICBs remain a major challenge in clinical settings. Indoleamine 2,3-dioxygenases (IDOs) are enzymes involved in tryptophan catabolism with a central immunosuppressive function within the tumor microenvironment. IDOs are over-ex...

Glucuronorhamnoxylan from Capsosiphon fulvescens inhibits the growth of HT-29 human colon cancer cells in vitro and in vivo via induction of apoptotic cell death.

Colorectal cancer is the third most diagnosed cancer and a leading cause of cancer death. Dissatisfaction with currently available anti-colorectal cancer drugs caused by unwanted side effects and low efficacy necessitates new therapeutic agents. In the present study, a sulfated glucuronorhamnoxylan polysaccharide (named SPS-CF) purified from a green alga Capsosiphon fulvescens was evaluated for it...

Cystatin are allocated into three major families. Family -I stefins, family -II cystatins and family -III kininogens, according to their amino acid sequence, molecular weight, carbohydrate content and disulphide bonds. It has been investigated tha...

Synergistic Activity of Paclitaxel, Sorafenib, and Radiation Therapy in advanced Renal Cell Carcinoma and Breast Cancer.

Advanced cancer has been shown to be associated with a higher percentage of epigenetic changes than with genetic mutations. Preclinical models have shown that the combination of paclitaxel, sorafenib, and radiation therapy (RT) plays a crucial role in renal cell carcinoma (RCC) and breast cancer. This study aimed to investigate the involvement of mitochondrial cytochrome c-dependent apoptosis in t...

miR-122 Targets X-Linked Inhibitor of Apoptosis Protein to Sensitize Oxaliplatin-Resistant Colorectal Cancer Cells to Oxaliplatin-Mediated Cytotoxicity.

Although oxaliplatin is one of the most effective chemotherapeutic drugs used to treat colorectal cancer (CRC), long-term administration usually induces acquired drug resistance during the course of treatment. Thus, there is an urgent need to explore novel strategies to improve the efficiency of cancer therapy. The aim of this study was to explore the effect of microRNA-122 (miR-122) on reversing ...
