BACKGROUND: Currently, transcatheter closure of perimembranous ventricular septal defect (pmVSD) is a widely accepted therapeutic modality. However, arrhythmias, especially postprocedural heart blocks, are a concern and outcomes are not very clear. This study explored the outcomes and risk factors of arrhythmias associated with transcatheter device closure of pmVSD. METHODS: A total of 395 patients diagnosed with pmVSD who successfully underwent transcatheter intervention between January 2010 and December 2015 in our center were retrospectively reviewed...

In 2012, an elderly immunocompromised man died from legionellosis at a hospital in Uppsala, Sweden. The patient had visited a dental ward at the hospital during the incubation period. Legionella spp. at a concentration of 2000 colony-forming units/L were isolated from the cupfiller outlet providing water for oral rinsing. Isolates from the patient and the dental unit were Legionella pneumophila serogroup 1, subgroup Knoxville and ST9. Pulsed-field gel electrophoresis and whole-genome sequencing strongly suggested that the isolates were of common origin...

In this project, fluid flow and fluid-structure interaction are studied for the human lower gastrointestinal (GI) region. The study consists of two steps. First, we apply meshing methods to discretize both the human lower GI model and the catheter model at sufficient resolution suitable for importing into a Finite Element Analysis (FEA) tool. For model discretization, 3D models of the colon reconstructed from human MRI slices are used to obtain the valid inlet and outlet boundary surfaces. To resolve the viscous boundary layer in flow studies, a special structure of the near-wall volumetric mesh is built by triangular prisms that construct quasi-structured, multiple near-boundary sub-layers...

We proposed a blood viscosity estimation method based on pressure-flow characteristics of oxygenators used during cardiopulmonary bypass (CPB) in a previous study that showed the estimated viscosity to correlate well with the measured viscosity. However, the determination of the parameters included in the method required the use of blood, thereby leading to high cost of calibration. Therefore, in this study we propose a new method to monitor blood viscosity, which approximates the pressure-flow characteristics of blood considered as a non-Newtonian fluid with characteristics of a Newtonian fluid by using the parameters derived from glycerin solution to enable ease of acquisition...

Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents...

BACKGROUND: There have been no comparative studies of open gastrojejunostomy (OGJ) and laparoscopic gastrojejunostomy (LGJ) in gastric cancer (GC) patients with gastric outlet obstruction (GOO) to explore both short- and long-term outcomes. The aim of this study was to compare the safety and feasibility of short-term oral intake as well as the long-term oncological outcome of OGJ and LGJ. METHODS: This was a retrospective study of 53 consecutive unresectable GC patients who underwent GJ for GOO in our institute...

Outbreaks caused by norovirus infection are common and occur throughout the year. Outbreaks can be related to food outlets either through a contaminated food source or an infected food handler. Both asymptomatic and symptomatic food handlers are potentially implicated in outbreaks, but evidence of transmission is limited. To understand potential food handler transmission in outbreak scenarios, epidemiological and microbiological data on possible and confirmed norovirus outbreaks reported in London and South East England in a 2-year period were reviewed...

PURPOSE OF REVIEW: Lower urinary tract symptoms are bothersome and significantly impair patient's quality of life. Incomplete bladder emptying affects both men and women, and has shown to increase in incidence with aging. Incomplete bladder emptying is consequent upon an inability of the detrusor muscle to adequately contract to completely empty the bladder, with or without an increased bladder outlet resistance; this can be defined urodynamically as detrusor underactivity (DUA). The symptom complex consequent upon DUA is referred to as underactive bladder (UAB)...

AIM: The current standard diagnostic test to evaluate bladder outlet obstruction (BOO) is pressure-flow study (PFS). The penile cuff test (PCT) was introduced as a non-invasive alternative to PFS to determine the isovolumetric bladder pressure and also flow rate. The aim of the study was to evaluate the diagnostic accuracy and acceptability of the PCT, compared to those of PFS, in the assessment of BOO in men. METHODS: A total of 146 consecutive men with an International Prostate Symptom Score (IPSS) >12 and lower urinary tract symptoms (LUTS) for >6 months were included in this single-institution, prospective, diagnostic study...

In this paper, we propose a microfluidic device capable of generating a retarding flow field for the sorting and separation of human motile sperm in a high-throughput manner. The proposed sorting/separation process begins with a rapid flow field in a straight-flow zone to carry sperm into a sorting zone to maintain the sperm's mobility. The sorting zone consists of a diffuser-type sperm sorter to differentiate sperm with different motilities based on the flowing upstream nature of human sperm in a retarding flow field...

Substandard and falsified antimalarial and antibiotic medicines represent a serious problem for public health, especially in low- and middle-income countries. However, information on the prevalence of poor-quality medicines is limited. In the present study, samples of six antimalarial and six antibiotic medicines were collected from 31 health facilities and drug outlets in southern Malawi. Random sampling was used in the selection of health facilities. For sample collection, an overt approach was used in licensed facilities, and a mystery shopper approach in nonlicensed outlets...

We sought to describe the prenatal features and postnatal outcomes of the "criss-cross heart" (CCH) with crossing atrioventricular connections as encountered in 5 cases and to review the literature regarding fetal diagnoses of this lesion. We reviewed the clinical history and fetal echocardiograms of 5 patients with a diagnosis of CCH encountered in our institution from 2010 to 2015. Affected pregnancies were identified through the University of Alberta fetal cardiology database. Fetal and postnatal echocardiograms, prenatal and postnatal clinical records, autopsy, and surgical reports were reviewed...

REVIEW
Juan Guzman-Negron, Sandip Vasavada
Patients with pelvic organ prolapse (POP) may present with a large combination of symptoms including overactive bladder (OAB) symptoms such as urgency, frequency, and urgency incontinence. The explanation as to why these symptoms are more prevalent in POP patients is not clearly understood, but there seems to be an overall agreement that prolapse-induced bladder outlet obstruction (BOO) may trigger bladder changes resulting in OAB symptoms. Presuming this to be true, many of the studies managing OAB in POP patients have focused on the surgical management of prolapse and its aftermath, which in many of the patients leads to improvement of OAB symptoms...

The aim of this study was to evaluate the genotoxic potential of an urban river - the Wei River in Xinxiang, China using randomly amplified polymorphic DNA (RAPD) assay in planarians. The results showed that the total number of polymorphic bands and varied bands in RAPD patterns of treated planarians decreased with the water sample site far away from the sewage outlet of a factory. In addition, the genome template stability of treated groups decreased and the degree of the decline was negatively related to the distance between the sample site and the sewage outlet, suggesting that the Wei River water had genotoxicity effects on planarians and strengthening the management of the Wei River was necessary...
