Mouse vs. Machine: The Game

Many modern video games built by big name companies are coded by a group of people together using, and possibly modifying, an already designed game engine. These games usually have another group of people creating the artwork. In this project, I coded and designed a video game from scratch, as well as created all the artwork used in the game. The player controls a mouse character who fights a variety of monsters. In order to create the complexity of the game, I implement basic neural networks as the enemy artificial intelligence, i.e. the decision making process of the enemy. It uses this to learn how to combat a player from the player’s actions, including movement and attacking. Movement is implemented through changing the player’s position on the screen, and attacking creates an image which causes damage to other characters. The program is coded in Python, using the Pygame library for displaying graphics. It is currently an alpha version, with the code built and all the gameplay elements in place. With the existing foundation, this game, “Mouse versus Machine”, can be extended into a full-fledged game in the future

Ovarian hyperstimulation syndrome: review and new classification criteria for reporting in clinical trials

STUDY QUESTION What is an objective approach that employs measurable and reproducible physiologic changes as the basis for the classification of ovarian hyperstimulation syndrome (OHSS) in order to facilitate more accurate reporting of incidence rates within and across clinical trials? SUMMARY ANSWER The OHSS flow diagram is an objective approach that will facilitate consistent capture, classification and reporting of OHSS within and across clinical trials. WHAT IS KNOWN ALREADY OHSS is a potentially life-threatening iatrogenic complication of the early luteal phase and/or early pregnancy after ovulation induction (OI) or ovarian stimulation (OS). The clinical picture of OHSS (the constellation of symptoms associated with each stage of the disease) is highly variable, hampering its appropriate classification in clinical trials. Although some degree of ovarian hyperstimulation is normal after stimulation, the point at which symptoms transition from those anticipated to those of a disease state is nebulous. STUDY DESIGN, SIZE, DURATION An OHSS working group, comprised of subject matter experts and clinical researchers who have significantly contributed to the field of fertility, was convened in April and November 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS The OHSS working group was tasked with reaching a consensus on the definition and the classification of OHSS for reporting in clinical trials. The group engaged in targeted discussion regarding the scientific background of OHSS, the criteria proposed for the definition and the rationale for universal adoption. An agreement was reached after discussion with all members. MAIN RESULTS AND THE ROLE OF CHANCE One of the following conditions must be met prior to making the diagnosis of OHSS in the context of a clinical trial: (i) the subject has undergone OS (either controlled OS or OI) AND has received a trigger shot for final oocyte maturation (e.g. hCG, GnRH agonist [GnRHa] or kisspeptin) followed by either fresh transfer or segmentation (cryopreservation of embryos) or (ii) the subject has undergone OS or OI AND has a positive pregnancy test. All study patients who develop symptoms of OHSS should undergo a thorough examination. An OHSS flow diagram was designed to be implemented for all subjects with pelvic or abdominal complaints, such as lower abdominal discomfort or distention, nausea, vomiting and diarrhea, and/or for subjects suspected of having OHSS. The diagnosis of OHSS should be based on the flow diagram. LIMITATIONS, REASONS FOR CAUTION This classification system is primarily intended to address the needs of the clinical investigator undertaking clinical trials in the field of OS and may not be applicable for the use in clinical practice or with OHSS occurring under natural circumstances. WIDER IMPLICATIONS OF THE FINDINGS The proposed OHSS classification system will enable an accurate estimate of the incidence and severity of OHSS within and across clinical trials performed in women with infertility.

Willingness to pay for one-stop anesthesia in pediatric day surgery

<p>Abstract</p> <p>Background</p> <p>This study assesses the parents' Willingness To Pay (WTP) for One Stop Anesthesia (OSA). OSA is part of a free screening procedure that determines the timing of the anesthesiological assessment. In OSA-positive patients, the preoperative assessment is carried out on the same day as the surgery. The OSA allows patients who have to undergo surgery in a pediatric day surgery to avoid accessing the pre-admission clinic.</p> <p>Method</p> <p>This is a descriptive cohort study. A sample of 106 parents were interviewed directly by means of a questionnaire. The questionnaire builds a hypothetical scenario where the interviewee has a chance to buy the OSA health service with the WTP. The WTP values are distributed in classes and are contingent to the market built in the questionnaire. The Chi Square and Cramer's V tests evaluate the WTP dependence on the parents' place of origin and occupation.</p> <p>Results</p> <p>The approximate average of the WTP classes is €87.21 per family. The Chi Square test relative to the WTP classes and the places of origin is statistically significant (p < 0.05). The Cramer's V test is 0.347 and points to a positive association between the two demographics. The Cramer's V test of the WTP classes and the types of job is 0.339 and indicates a positive association.</p> <p>Conclusion</p> <p>Nearly 90% of pediatric patients who were screened for timing the preoperative assessment are true positives to OSA. This allows doing away with the pre-hospitalization, with definite advantages for the families. This screening is a health service that families would be hypothetically willing to pay.</p

Cryopreservation of hazelnut (Corylus avellana l.) axillary buds from in vitro shoots using the droplet vitrification method

Cryopreservation by droplet vitrification was applied to hazelnut (Corylus avellana L.). axillary buds of the Italian cultivated variety Tonda Gentile Romana, which were collected from in vitro growing shoots, immersed in ice cooled PVS2 or PVS3 for 60 or 90 min, then transferred to a droplet of vitrification solution, placed on a strip of aluminium foil, and plunged into liquid nitrogen (LN). Additionally, the effect on the recovery of the mother plant after cryopreservation was evaluated, following a cold pre-treatment at 4◦C for 3 months. The highest regrowth percentage (56.7%) was obtained after applying PVS3 for 60 min, while the application of PVS2 for the same amount of time reduced regrowth to 41.5%. Increasing the exposure to vitrification solutions to 90 min reduced regrowth to 43.3% when PVS3 was applied, and 35.6% if PVS2 was used. The cold pre-treatment on the mother plant did not significantly improve overall regrowth. The cryopreservation process did not decline the rooting ability of the recovered shoot

The current provision of community-based teaching in UK medical schools: an online survey and systematic review

Objective: To evaluate the current provision and outcome of community-based education (CBE) in UK medical schools. Design and data sources: An online survey of UK medical school websites and course prospectuses and a systematic review of articles from PubMed and Web of Science were conducted. Articles in the systematic review were assessed using Rossi, Lipsey and Freeman’s approach to programme evaluation. Study selection: Publications from November 1998 to 2013 containing information related to community teaching in undergraduate medical courses were included. Results: Out of the 32 undergraduate UK medical schools, one was excluded due to the lack of course specifications available online. Analysis of the remaining 31 medical schools showed that a variety of CBE models are utilised in medical schools across the UK. Twenty-eight medical schools (90.3%) provide CBE in some form by the end of the first year of undergraduate training, and 29 medical schools (93.5%) by the end of the second year. From the 1378 references identified, 29 papers met the inclusion criteria for assessment. It was found that CBE mostly provided advantages to students as well as other participants, including GP tutors and patients. However, there were a few concerns regarding the lack of GP tutors’ knowledge in specialty areas, the negative impact that CBE may have on the delivery of health service in education settings and the cost of CBE. Conclusions: Despite the wide variations in implementation, community teaching was found to be mostly beneficial. To ensure the relevance of CBE for ‘Tomorrow’s Doctors’, a national framework should be established, and solutions sought to reduce the impact of the challenges within CBE. Strengths and limitations of this study: This is the first study to review how community-based education is currently provided throughout Medical Schools in the UK. The use of Rossi, Lipsey and Freeman’s method of programme evaluation means that the literature was analysed in a consistent and comprehensive way. However, a weakness is that data from the online survey was obtained from online medical school prospectuses. This means the data may be incomplete or out of date. Data in the literature review may also be skewed by publication bias
