A cesarean scar ectopic pregnancy (CSEP) is a fairly uncommon presentation wherein the conceptus is implanted deep in the myometrium and at the exact scar site of the previous cesarean section. There are various CSEP management options that range from medical treatment to surgical interventions such as dilatation and curettage, laparoscopic excision, resection by laparotomy, or, sometimes, a combination of these modalities. Establishing a diagnosis of CSEP can be challenging. Given the relatively rare incidence of CSEP, its management is controversial and current standards of therapy have been derived from data obtained from a limited number of patients...

Membrane functionality is crucial in microfluidics for realizing operations such as filtration, separation, concentration, signaling among cells and gradient generation. Currently, common methods often sandwich commercially available membranes in multi-layer devices, or use photopolymerization or temperature-induced gelation to fabricate membrane structures in one-layer devices. Biofabrication offers an alternative to forming membrane structures with biomimetic materials and mechanisms in mild conditions. We have recently developed a biofabrication strategy to form parallel biopolymer membranes in gas-permeable polydimethylsiloxane (PDMS) microfluidic devices, which used positive pressure to dissipate air bubbles through PDMS to initiate membrane formation but required careful pressure balancing between two flows...

Since circulating tumor cells (CTCs) are tumor cells which are found in the blood of cancer patients, CTCs are potential tumor markers, so a rapid isolation of CTCs is desirable for clinical applications. In this paper, a three-dimensional polystyrene (PS) microfiber fabric with vacuum aspiration system was developed for capturing CTCs within a short time. Various microfiber fabrics with different diameters were prepared by the electrospinning method and optimized for contact frequency with cells. Vacuum aspiration utilizing these microfiber fabrics could filter all cells within seconds without mechanical damage...

Malawi has one of the highest maternal mortality ratios in the world. Unsafe abortions are an important contributor to Malawi's maternal mortality and morbidity, where abortion is illegal except to save the woman's life. Postabortion care (PAC) aims to reduce adverse consequences of unsafe abortions, in part by treating incomplete abortions. Although global and national PAC policies recommend manual vacuum aspiration (MVA) for treatment of incomplete abortion, usage in Malawi is low and appears to be decreasing, with sharp curettage being used in preference...

California statewide West Nile virus (WNV) minimum infection rates in Culex thriambus Dyar mosquitoes are high; however, few specimens are submitted and tested each year, as their distribution seems limited to larval habitats along riparian systems. To evaluate the role of Cx. thriambus in the amplification, maintenance, and overwintering of WNV in Lake County, CA, the bionomics and vector potential of the species was investigated during 2014 and 2015. Culex thriambus was the most abundant mosquito species, with 1,153 adults and 7,624 immatures collected by vacuum aspiration and dip sampling, respectively, at the primary study site...

The authors report a case of an 84-year-old woman with an exposed mandibular plate after reconstruction, which finally healed with combination therapy using vacuum-assisted closure therapy and hyperbaric oxygen therapy. The woman was diagnosed with mucosal carcinoma of the right oral cavity. During reconstruction after segmental excision of the mandible, a titanium plate was selected based on several risk factors. After the operation, the plate became exposed at the center of the chin. A second surgery was deemed inappropriate because of her age, malnutrition, and recurrent aspiration pneumonia...

Contraception is an essential element of high-quality abortion care. However, women seeking abortion often leave health facilities without receiving contraceptive counselling or methods, increasing their risk of unintended pregnancy. This paper describes contraceptive uptake in 319,385 women seeking abortion in 2326 public-sector health facilities in eight African and Asian countries from 2011 to 2013. Ministries of Health integrated contraceptive and abortion services, with technical assistance from Ipas, an international non-governmental organisation...

Purpose. To evaluate comparative aspiration flow performance and also vitrectomy operating time efficiency using a double-cutting open port vitreous cutting system incorporated in a two-dimensional cutting (TDC, DORC International) vitrectome design versus standard vitreous cutter. Methods. In vitro investigations compared aspiration flow rates in artificial vitreous humor at varying cutter speeds and vacuum levels using a TDC vitrectome and a standard vitrectome across different aspiration pump systems. A prospective single-centre clinical study evaluated duration of core vitrectomy in 80 patients with macular pucker undergoing 25-gauge or 27-gauge vitrectomy using either a TDC vitrectome at 16,000 cuts per minute (cpm) or standard single-cut vitrectome, combined with a Valve Timing intelligence (VTi) pump system (EVA, DORC International)...

BACKGROUND: Right heart thrombus in the absence of structural heart disease, atrial fibrillation, or intracardiac catheter is rare. It typically represents a thrombus migrating from the venous system to the lung, known as thrombi-in-transit, and can lead to a life-threatening pulmonary embolism. The optimal therapy for thrombi-in-transit remains controversial. We report our experience using percutaneous removal of right heart thrombus using vacuum aspiration. METHODS: Patients with right atrial mass who were hemodynamically stable and underwent vacuum thombectomy using the AngioVac system (AngioDynamics) at our institution were included in this analysis...
