Background: The aim of this study was to compare the effects of easy and difficult embryo transfers (ET) on implantation and pregnancy rates.
Materials And Methods: In this prospective study, we analyzed the results of 706 ET procedures over a 12-month period. An easy ET was defined as a transfer that occurred without the use of force or other instrumentation. A difficult ET was defined as the use of force for catheter placement, and/or the use of additional instruments, and/or manipulation. Pregnancy rate was compared between patients with easy or difficult ETs.
Results: There was a significantly higher implantation rate in the easy group (21.7%) compared to the difficult group (12.1%, p<0.05).The easy group had a higher pregnancy rate (38.1%) compared to patients who had difficult ETs (21.4%; p<0.05).
Conclusion: Any uterine manipulation during ET adversely affects in vitro fertilization (IVF). Precaution should be taken to identify possibly difficult ET cases in advance.

Honeydew honey is less studied than nectar honey, although it is characterized by peculiar nutritional properties. This is mainly due to its challenging production, which leads to easy counterfeiting and difficult valorization. This contribution aims to provide a comprehensive characterization of the physico-chemical, palynological, functional, and food safety properties of a large sampling of honeydew honeys collected throughout Italy.

: Accurate target definition, treatment planning and delivery increases local tumor control for radiotherapy by minimizing collateral damage. To achieve this goal for uveal melanoma (UM), tantalum fiducial markers (TFMs) were previously introduced in proton and photon beam radiotherapy. However, TFMs cause pronounced scattering effects in imaging that make the delineation of small tumors difficult.

This study investigates the process of planning for future inpatient resources (beds, staff and costs) for maternity (pregnancy and childbirth) services. The process of planning is approached from a patient-centered philosophy; hence, how do we discharge a suitably rested healthy mother who is fully capable of caring for the newborn baby back into the community? This demonstrates some of the difficulties in predicting future births and investigates trends in the average length of stay. While it is relatively easy to document longer-term (past) trends in births and the conditions relating to pregnancy and birth, it is exceedingly difficult to predict the future nature of such trends.

Chronic migraine (CM) is the ultimate and most burdensome form of the transformation from episodic migraine (EM), called chronification. The mechanism behind migraine chronification is poorly known and difficult to explore as CM has the same spectrum of pathogenesis as EM and the EM-CM transition is bidirectional. Central sensitization (CS) is a key phenomenon in migraine: its mechanisms include disturbed neural plasticity, which is the ability of the nervous system to adapt to endo- and exogenous changes.

Maximizing the amount of work harvested from an environment is important for a wide variety of biological and technological processes, from energy-harvesting processes such as photosynthesis to energy storage systems such as fuels and batteries. Here, we consider the maximization of free energy-and by extension, the maximum extractable work-that can be gained by a classical or quantum system that undergoes driving by its environment. We consider how the free energy gain depends on the initial state of the system while also accounting for the cost of preparing the system.
