Disseminated thymoma in pleural fluid: An unusual case.

Thymic epithelial tumours show characteristic cytological features on fine-needle aspiration cytology, however the cytological features of thymoma in fluid cytology are not well described. We present the case of a 77 year-old-woman with known pleural dissemination of type B2/B3 thymoma presenting with shortness of breath and orthopnoea due to a pleural effusion. Cytological evaluation of the pleural fluid showed cellular smears composed of numerous small lymphocytes with small numbers of admixed mesothelial cells.

Evaluation of the Fast Prior Authorization Technology Highway.

Background: Prior authorization (PA) is a utilization management tool used by health plans and pharmacy benefit managers where the payer requires additional documentation from health care providers before authorization of payment for a medication or procedure. PA processes are hypothesized to be more efficient if electronic transmission is utilized instead of manual submission.

Objective: To evaluate the impact of electronic PA (ePA) on approval rate and time to decision and to assess health care provider perception of using ePA.

Body mass index and in-hospital postoperative complications following primary total hip arthroplasty.

Background: The influence of obesity measured in terms of body mass index (BMI) on the complication rates following total hip arthroplasty (THA) is a matter of debate.

Methods: This retrospective study conducted at a tertiary referral centre at Brisbane, Australia, examines the association between BMI and in-hospital postoperative complications, length of operating time and duration of hospital stay in 964 patients, who underwent THA from 2006 to 2010.

Results: Amongst patients undergoing primary THA, when compared to the normal weight patients, those with BMI between 25 kg/m and 29.

Transforming the future of health together: The Learning Health Systems Consensus Action Plan.

The Learning Health Community is an emergent global multistakeholder grassroots incipient movement bonded together by a set of consensus developed at the 2012 Learning Health System (LHS) Summit. The Learning Health Community's Second LHS Summit was convened on December 8 to 9, 2016 building upon LHS efforts taking shape in order to achieve consensus on actions that, if taken, will advance LHSs and the LHS vision from what remain appealing concepts to a working reality for improving the health of individuals and populations globally. An iterative half-year collaborative revision process following the Second LHS Summit led to the development of the .

Factors That Influence Women to Disclose Sexual Assault History to Health Care Providers.

Objective: To examine women's experiences with sexual assault screening by health care professionals and identify factors that influence women to disclose their sexual assault history to providers.

Design: Cross-sectional descriptive survey with correlational analysis.

Setting: On-line survey distributed nationally.

Recommendations for fluoride limits in drinking water based on estimated daily fluoride intake in the Upper East Region, Ghana.

Both dental and skeletal fluorosis caused by high fluoride intake are serious public health concerns around the world. Fluorosis is particularly pronounced in developing countries where elevated concentrations of naturally occurring fluoride are present in the drinking water, which is the primary route of exposure. The World Health Organization recommended limit of fluoride in drinking water is 1.

Persistence of seeds from crops of conventional and herbicide tolerant oilseed rape (Brassica napus).

A series of rotation experiments at five sites over four years has explored the environmental and agronomic implications of growing herbicide tolerant oilseed rape and sugar beet. This paper reports on the population dynamics of volunteer rape (Brassica napus). The experiments compared four winter oilseed rape (WOSR) cultivars: a conventional cultivar (Apex) and three developmental cultivars either genetically modified (GM) to be tolerant to glyphosate or glufosinate, or conventionally bred to be tolerant to herbicides of the imidazolinone group.

Flow-injection analysis with fluorescence detection for the determination of trace levels of ammonium in seawater.

A method using flow-injection, gas-diffusion, derivatisation and then fluorescent detection has been established for ammonium ion determination in seawater. The fluorescent derivative formed by reacting ortho-phthaldialdehyde (OPA) and sulfite with ammonia gives high sensitivity while removing potential interferences. This is required to measure the low concentrations of ammonium often seen in the open ocean.

Herbicidal action of 2-hydroxy-3-alkyl-1,4-naphthoquinones.

The main mode of herbicidal activity of 2-hydroxy-3-alkyl-1,4-naphthoquinones is shown to be inhibition of photosystem II (PSII). The herbicidal and in vitro activities have been measured and correlated with their (Log)octanol/water partition coefficients (Log Ko/w). The length of the 3-n-alkyl substituent for optimal activity differed between herbicidal and in vitro activity.
