Group B streptococci (GBS; Streptococcus agalactiae) are the leading cause of neonatal invasive diseases and are also important pathogens for elderly adults. Until now, nearly all GBS with reduced penicillin susceptibility (PRGBS) have shown β-hemolytic activity and grow on sheep blood agar. However, we have previously reported three PRGBS clinical isolates harboring a CylK deletion that form small less hemolytic colonies. In this study, we examined the causes of small, less hemolytic colony formation in these clinical isolates...

Statin therapy is regarded as an effective medication to reduce cardiovascular events in patients at higher risk for future incidence of coronary artery disease. However, very few studies have been conducted to examine its implementation in non-Western real-world practice. In this study, we sought to describe statin prescription patterns in relation to patient characteristics in a Japanese multicenter percutaneous coronary intervention (PCI) registry as a foundation for quality improvement. We studied 15,024 patients that were prospectively enrolled in the Japan Cardiovascular Database-Keio interhospital Cardiovascular Study Registry from January 2009 to August 2014...

The aim of this study was to evaluate prognostic values of ambulatory blood pressure (ABP) and clinic blood pressure (CBP) in diabetic patients with hypertension. A total of 450 diabetic hypertensive patients without established cardiovascular diseases were enrolled and 416 patients who had finished 12months' follow-up were included in final analysis. Baseline data were collected and Cox proportional hazards regression analysis was used to evaluate prognostic value of ABP and CBP. Compared to those without study endpoints (n = 370), those experienced study endpoints (n = 46) were more elderly and more likely to be male, and had longer hypertension duration (7...

SIGNIFICANCE The incidence of cardiovascular events increases by aging, representing the main cause of death in old population. Aging is associated with over-production of reactive oxygen species (ROS), which may affect clotting and platelet activation, and impair endothelial function so predisposing elderly patients to thrombotic complications. RECENT ADVANCES There are increasing evidences to suggest that aging is associated with an imbalance between oxidative stress and antioxidant status. Thus, up-regulation of ROS-producing enzymes such as nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and myeloperoxidase, along with down-regulation of antioxidant enzymes, such as superoxide dismutase and glutathione peroxidase, occur during aging...

Atypical fibroxanthoma (AFX) is a rare spindle cell neoplasm predominantly found on the head and neck of elderly individuals with sun-damaged skin, with no evidence-based guidelines for their management. A systematic retrospective review of the literature focusing on treatment modality found a recurrence and metastasis rate of 8.0% (5.6% when adjusted for incomplete excisions) and 0.5% for local excision and 4.6% and 3.2% for Mohs micrographic surgery, respectively. Our results suggest that with clear surgical margins, AFX is unlikely to recur and metastases are rare, with significantly higher rates in the immunosuppressed population...

Primary cutaneous large B‑cell lymphomas (PCBLT), EBV-positive large B‑cell lymphomas, not otherwise specified (EBV+ DLBCL, NOS), and primary cutaneous intravascular large B‑cell lymphomas (PCIVLBL) are recognized as cutaneous lymphomas with intermediate to poor prognosis. Differentiation from indolent B‑cell lymphomas or other pathologies of the skin can be complex, both clinically and histologically, but vital for the outcome of the patient. The combination of immunotherapy and polychemotherapy regimens, such as R‑CHOP, has led to significant improvements in prognosis, especially in diffuse large B‑cell lymphomas...

Electronic Health Record (EHR)-derived data is a valuable resource for research, and efforts are underway to overcome some of its limitations by using data from external sources to gain a fuller picture of patient characteristics, symptoms, and exposures. Our goal was to assess the utility of augmenting EHR data with geocoded patient addresses to identify geospatial variation of disease that is not explained by EHR-derived demographic factors. Using 2011-2014 encounter data from 27,604 University of Pennsylvania Hospital System asthma patients, we identified factors associated with asthma exacerbations: risk was higher in female, black, middle aged to elderly, and obese patients, as well as those with positive smoking history and with Medicare or Medicaid vs...

Neurodegenerative diseases are a devastating group of conditions that cause progressive loss of neuronal integrity, affecting cognitive and motor functioning in an ever-increasing number of older individuals. Attempts to slow neurodegenerative disease advancement have met with little success in the clinic; however, a new therapeutic approach may stem from classic interventions, such as caloric restriction, exercise, and parabiosis. For decades, researchers have reported that these systemic-level manipulations can promote major functional changes that extend organismal lifespan and healthspan...

Although a normal member of the gastrointestinal and vaginal microbiota, group B Streptococcus (GBS) can also occasionally be the cause of highly invasive neonatal disease and is an emerging pathogen in both elderly and immunocompromised adults. Neonatal GBS infections are typically transmitted from mother to baby either in utero or during passage through the birth canal and can lead to pneumonia, sepsis, and meningitis within the first few months of life. Compared to the adult immune system, the neonatal immune system has a number of deficiencies, making neonates more susceptible to infection...

BACKGROUND: Amnestic mild cognitive impairment (aMCI) is characterized by cognitive functional decline, especially in memory. Resting-state functional magnetic resonance imaging (fMRI) has been widely used in neuroimaging studies that explore alterations between patients and normal individuals to elucidate the pathological mechanisms of different diseases. The current study was performed to investigate alterations in the functional connectivity of the default mode network (DMN) in aMCI patients compared to healthy elderly controls, as well as further define the association between neurological alterations and memory function...

BACKGROUND: New generation hormone-therapies (NGHT) targeting the androgen signalling pathway are nowadays proposed to elderly patients with metastatic castration-resistant prostate cancer (CRPCa). The impact of these treatments on cognitive function has never been evaluated whereas cognitive impairment may have an impact on the autonomy and the treatment adherence. The aim of this study is to prospectively assess the incidence of cognitive impairment in elderly men after treatment by NGHT for a metastatic CRPCa...

Brain abnormalities in neuromyelitis optica spectrum disorder (NMOSD) are highly heterogeneous and often non-specific. Extensive white matter involvement has been described and frequently manifests with encephalopathy requiring prompt intervention. Rarely, this may represent the only manifestation at onset without concurrent suggestive features of the disease, thus making diagnosis challenging. NMOSD may potentially occur at any age, but it seems that this disorder has distinctive clinical features in the elderly...

Left ventricular aneurysms and pseudoaneurysms are complications of myocardial infarction. With advances in percutaneous coronary intervention, development of thrombolytic agents, and early initiation of treatment with angiotensin-converting enzyme inhibitors to decrease afterload and inhibit left ventricular remodeling, these complications have become much less common. Here, we report an incidental finding of a giant aneurysm of the left ventricle with associated thrombus and mural calcifications in an elderly male patient who presented to his primary care physician for abdominal pain and denied any prior coronary artery disease...

Sarcopenia is a complex and multifactorial disease that includes a decrease in the number, structure and physiology of muscle fibers, and age-related muscle mass loss, and is associated with loss of strength, increased frailty, and increased risk for fractures and falls. Treatment options are suboptimal and consist of exercise and nutrition as the cornerstone of therapy. Current treatment principles involve identification and modification of risk factors to prevent the disease, but these efforts are of limited value to the elderly individuals currently affected by sarcopenia...
