With an increasing trend of patients with young-onset colorectal cancer (CRC), risks of second primary cancers (SPCs) among them become a concerning issue. We aimed to define the detailed risk and site-distributed patterns of SPCs in young CRC individuals (age ≤50). A population-based cohort were identified from the Surveillance, Epidemiology, and End Results database between 1973 and 2013. Standardized incidence ratios (SIRs) and absolute excess risk (AER) were calculated to assess the risk for SPCs compared with the general population...

The role of thecal glands in the ovary of birds remains controversial. Using transmission electron microscopy and immunohistochemistry, immunohistochemical localisation of cyclooxygenase I and II (COX-1 and COX-2), oestrogen receptor α and β (ER-α and ER-β), androgen receptor (AR) and progesterone receptor (PR), a detailed analysis of the thecal glands was performed. Our ultrastructural studies revealed that the thecal glands of the quail ovary consist of 2 cell types, steroid-producing cells (SPCs) and enclosing cells (ENCs)...

BACKGROUND: The right to adequate outpatient palliative care has existed for several years in Germany. In recent years outpatient palliative care has developed very positively. Nevertheless, in emergency situations paramedics and emergency physicians were often included in the care of palliative care of patients. The aim of our study was to investigate the cooperation between outpatient palliative care teams and the emergency medical services. Another aim was to identify structural realities and based on these to discuss the possibilities in the optimization of outpatient palliative medical emergency situations...

Introduction: Around 3.2%-8.4% of patients receive venoarterial (VA) extracorporeal membrane oxygenation (ECMO) support after pediatric cardiac surgery. The desired outcome is "bridge-to-recovery" in most cases. There is no universally agreed protocol, and given the associated costs and complications rates, the decisions as of when and when not to institute VA ECMO are largely empirical. Methods: A retrospective review of the ECMO database at the Scottish Pediatric Cardiac Services (SPCS) was undertaken...

Clostridium perfringens produces various exotoxins and enzymes that cause food poisoning and gas gangrene. The genes involved in virulence are regulated by the agr-like quorum sensing (QS) system, which consists of a QS signal synthesis system and a VirSR two-component regulatory system (VirSR TCS) which is a global regulatory system composed of signal sensor kinase (VirS) and response regulator (VirR). We found that the perfringolysin O gene (pfoA) was transiently expressed during mid-log phase of bacterial growth; its expression was rapidly shut down thereafter, suggesting the existence of a self-quorum quenching (sQQ) system...

BACKGROUND: The authors' systematic review indicated an increasing trend in the risk of second primary cancers (SPCs) from the 1980s to 2000 when considering studies from the United States and Australia. It is uncertain whether this trend has continued to increase since 2000. METHODS: The current study was a population-based study of 51,802 individuals with adult-onset cancers identified in the Tasmanian Cancer Registry. Patients with a first cancer diagnosis made between 1980 and 2009 were followed up to December 2013...

Data on efficacy outcomes of endovascular versus surgical revascularization in patients with critical limb ischemia (CLI) in contemporary practice are limited. In this prospective cohort study, 353 consecutive patients with CLI were enrolled and allocated to endovascular (PTA [percutaneous transluminal angioplasty]), surgical (SURG), or no revascularization (No REVASC) after interdisciplinary consensus. Outcome measures were sustained primary clinical success (sPCS; survival without major amputation, repeated target extremity revascularization, and freedom from CLI), limb salvage, and amputation-free survival...

Tissue engineering techniques provide a great potential to de novo construct a histological bladder. Smooth muscle regeneration is extremely important for the functional recovery of engineered neo-bladder. However, many challenges remain for the use of bladder smooth muscle cells (SMCs) as the cell sources. Recent evidences showed that smooth muscle progenitor cells (SPCs) in the peripheral blood have the capacity of differentiating into SMCs, while their use for bladder regeneration hasn't yet been reported...

INTRODUCTION: As cancer survivors continue to live longer, the incidence of second primary cancers (SPCs) will also rise. Relatively little is understood about the diagnostic pathway for SPCs, how people appraise, interpret symptoms and seek help for a second different cancer and the experiences (including challenges) of healthcare providers relating to SPCs. This study aims to systematically appraise and synthesise the literature on the pathways to diagnosis of an SPC and the associated patient and healthcare provider experiences...

The reasons for the publication of current expert consensus statement after 4 years from the previous one are: the growing number of evidence on the benefits of the use of single-pill combinations (SPCs) in hypertension (also with concomitant dyslipidaemia), the extension of indications for their use in the hypertension management algorithm and the emergence in recent years after the publication of Polish Society of Hypertension experts' position statement in 2013 of new types of SPCs available to doctors in Poland, including triple-drug combinations of antihypertensives and the so-called "hybrids" SPCs containing not only antihypertensive drugs but also statins...

This article adopts a realist approach to evaluate a social prescribing pilot in the areas of Hackney and City in London (United Kingdom). It unpacks the contextual factors and mechanisms that influenced the development of this pilot for the benefits of GPs, commissioners and practitioners, and reflects on the realist approach to evaluation as a tool for the evaluation of health interventions. Primary care faces considerable challenges including the increase in long-term conditions, GP consultation rates, and widening health inequalities...

INTRODUCTION: Signal detection from healthcare databases is possible, but is not yet used for routine surveillance of drug safety. One challenge is to develop methods for selecting signals that should be assessed with priority. AIM: The aim of this study was to develop an automated system combining safety signal detection and prioritization from healthcare databases and applicable to drugs used in chronic diseases. METHODS: Patients present in the French EGB healthcare database for at least 1 year between 2005 and 2015 were considered...

We use Monte Carlo simulations to investigate the thermodynamic behavior of soft porous crystal (SPC) adsorbents under the influence of an external barostat. We consider SPCs that naturally exhibit polymorphism between crystal forms of two distinct pore sizes. In the absence of barostatting, these crystals may be naturally divided into two categories depending on their response to stress applied by the adsorbate fluid: those which macroscopically deform and change the volume of their unit cell ("breathing") and those which instead undergo internal rearrangements that change the adsorbate-accessible volume without modifying the unit cell volume ("gate-opening")...

Background: In Japan, there has been a lot of reports showing an association between facial flushing after light alcohol consumption and heterozygosity for inactive aldehyde dehydrogenase-2 (ALDH2). Persons with inactive ALDH2 may have a higher risk of alcohol-related oral, pharyngeal and esophageal cancers, compared with those with wild-type ALDH2. The purpose of this study was to examine whether flushers with oral or pharyngeal squamous cell carcinoma have an increased risk of synchronous or metachronous cancer of the upper gastrointestinal (UGI) tract...

The single-pill combination (SPC) comprising nebivolol (5 mg), a vasodilatory β1 -selective antagonist/β3 -agonist, and valsartan (80 mg), a renin-angiotensin-aldosterone system inhibitor, is the only Food and Drug Administration-approved β-blocker/renin-angiotensin-aldosterone system inhibitor SPC for hypertension. Additive effects of four nebivolol/valsartan SPC doses (5 mg/80 mg, 5/160 mg, 10/160 mg, 10/320 mg nebivolol/valsartan) were compared with five Food and Drug Administration-approved non-β-blocker/renin-angiotensin-aldosterone system inhibitor SPCs (aliskiren/hydrochlorothiazide, aliskiren/amlodipine, valsartan/amlodipine, aliskiren/valsartan, and telmisartan/amlodipine)...

BACKGROUND: Cancer survivors are at risk of developing a second primary cancer (SPC) later in life because of persisting effects of genetic and behavioural risk factors, the long-term sequelae of chemotherapy, radiotherapy and the passage of time. This is the first study with Austrian data on an array of entities, estimating the risk of SPCs in a population-based study by calculating standardized incidence ratios (SIRs). METHODS: This retrospective cohort study included all invasive incident cancer cases diagnosed within the years 1988 to 2005 being registered in the Tyrol and Vorarlberg Cancer Registries...

To explore the roles of various K+ channels in regulating the spontaneous activity of bladder muscularis mucosae (MM) that is considered to play an important role in maintaining mucosal function. Effects of K+ channel modulators on electrical and contractile activity in the guinea-pig bladder MM were examined using intracellular microelectrode and isometric tension recording. The MM predominately generated bursting spontaneous action potentials (SAPs) and phasic contractions (SPCs) that were blocked by nifedipine (1µM)...
