Introduction: The effective method of treatment of Polycystic Overy Syndrome (PCOS) is lifestyle modification. The aim of this study was to evaluate the effect of 12 weeks aerobic exercise on DHEAso4, 17OH-Progestron Concentrations, number of follicles and menstrual condition of women with PCOS. Methods: In this clinical trial, 40 PCOS patients lean (BMI<20) and obese (BMI>25) randomly divided ...

Lean health care is one of new managing approaches putting the patient at the core of each change. Lean construction is based on visualization for understanding and prioritizing imporvments. By using only visualization techniques, so much important information could be missed. In order to prioritize and select improvements, it’s essential to integrate new analysis tools to achieve a good unders...

Background and Aim: The growing healthcare expenses, technological advancements and increasing competition in healthcare services, brings up new challenges for healthcare industry in providing appropriate services to customers. The Lean methodology, which is a managerial approach, provides tools necessary to eliminate waste and increase customer satisfaction through increasing quality of the se...

To cite: Margolius D, Ranji SR. BMJ Qual Saf 2015;24:477–479. Front-line healthcare workers are the first to witness the everyday errors that occur in patient care—when a medication dose is delayed, or when an unnecessary test causes harm. Residents and interns are those front-line workers in academic medical centres, working for up to 80 h a week for at least 3 years (in the USA). Just as hosp...

BACKGROUND Acute ozone (O(3)) exposure results in greater inflammation and airway hyperresponsiveness (AHR) in obese versus lean mice. OBJECTIVES We examined the hypothesis that these augmented responses to O(3) are the result of greater signaling through tumor necrosis factor receptor 2 (TNFR2) and/or interleukin (IL)-13. METHODS We exposed lean wild-type (WT) and TNFR2-deficient (TNFR2(-/...

I is common for a retailer to sell products from competing manufacturers. How then should the firms manage their contract negotiations? The supply chain coordination literature focuses either on a single manufacturer selling to a single retailer or one manufacturer selling to many (possibly competing) retailers. We find that some key conclusions from those market structures do not apply in our ...

In modern times, far-reaching changes especially in production have taken place. Lean manufacturing systems require delivery strategies such as just-in-time or just-in-sequence that are synchronized with production demand to make sure the optimal amount of inventory is on hand at any time. This development comes along with both increasing dependence and cross-linking of inhouse-logistics system...

This note collects together some observations I made in the context of comparing graph properties by the graph minor relation [ 2 ], but which apply more generally to arbitrary subsets of a given poset. They are all simple and ought to be well known, but I have been unable to find a source. The main observation is that the subsets of an infinite poset P can be decomposed in a way that resembles...
