The changing face of cognitive gender differences in Europe

Cognitive gender differences and the reasons for their origins have fascinated researchers for decades. Using nationally representative data to investigate gender differences in cognitive performance in middle-aged and older populations across Europe, we show that the magnitude of these differences varies systematically across cognitive tasks, birth cohorts, and regions, but also that the living conditions and educational opportunities individuals are exposed to during their formative years are related to their later cognitive performance. Specifically, we demonstrate that improved living conditions and less gender-restricted educational opportunities are associated with increased gender differences favoring women in some cognitive functions (i.e., episodic memory) and decreases (i.e., numeracy) or elimination of differences in other cognitive abilities (i.e., category fluency). Our results suggest that these changes take place due to a general increase in women's cognitive performance over time, associated with societal improvements in living conditions and educational opportunities

Gender and sexual orientation differences in cognition across adulthood : age is kinder to women than to men regardless of sexual orientation

Despite some evidence of greater age-related deterioration of the brain in males than in females, gender differences in rates of cognitive aging have proved inconsistent. The present study employed web-based methodology to collect data from people aged 20-65 years (109,612 men; 88,509 women). As expected, men outperformed women on tests of mental rotation and line angle judgment, whereas women outperformed men on tests of category fluency and object location memory. Performance on all tests declined with age but significantly more so for men than for women. Heterosexuals of each gender generally outperformed bisexuals and homosexuals on tests where that gender was superior; however, there were no clear interactions between age and sexual orientation for either gender. At least for these particular tests from young adulthood to retirement, age is kinder to women than to men, but treats heterosexuals, bisexuals, and homosexuals just the same

Reconstruction after partial duodenectomy using a Roux-en-Y lateral duodenojejunostomy: a single center retrospective analysis

Oncologic resections of the second and third portions of the duodenum (D2 and D3) via partial duodenectomy can pose a challenging clinical problem. The duodenum must be repaired primarily or reconstructed. We have adopted a method of reconstruction using a Roux-en-Y duodenojejunostomy (D-J) in patients with extensive duodenal wall loss. We report our results in the first series of these cases. A retrospective review of patients who underwent post partial duodenectomy with reconstruction between June 2004 and March 2014 was performed. Five patients underwent partial duodenectomy with reconstruction. Two had resection for extrinsic tumors (colonic adenocarcinoma). Three had intrinsic duodenal tumors (one tubular adenoma, one adenocarcinoma and one gastrointestinal stromal tumor). All patients were reconstructed via retrocolic Roux-en-Y D-J. Mean estimated blood loss was 470 mL with median length of stay of 11 days. Post-operative complications included three intra-abdominal abscesses, one superficial wound infection and one gastrointestinal bleed. There were no anastomotic leaks, injuries to the ampulla of Vater or mortalities. In conclusion, partial duodenectomy of lateral D2/D3 with Roux-en-Y D-J is a relatively safe and effective alternative to partial duodenectomy with primary repair or pancreaticoduodenectomy for certain tumors of the duodenum

Practical examination of bystanders performing Basic Life Support in Germany: a prospective manikin study

<p>Abstract</p> <p>Background</p> <p>In an out-of-hospital emergency situation bystander intervention is essential for a sufficient functioning of the chain of rescue. The basic measures of cardiopulmonary resuscitation (Basic Life Support – BLS) by lay people are therefore definitely part of an effective emergency service of a patient needing resuscitation. Relevant knowledge is provided to the public by various course conceptions. The learning success concerning a one day first aid course ("LSM" course in Germany) has not been much investigated in the past. We investigated to what extent lay people could perform BLS correctly in a standardised manikin scenario. An aim of this study was to show how course repetitions affected success in performing BLS.</p> <p>Methods</p> <p>The "LSM course" was carried out in a standardised manner. We tested prospectively 100 participants in two groups (<b>Group 1: </b>Participants with previous attendance of a BLS course; <b>Group 2: </b>Participants with no previous attendance of a BLS course) in their practical abilities in BLS after the course. Success parameter was the correct performance of BLS in accordance with the current ERC guidelines.</p> <p>Results</p> <p>Twenty-two (22%) of the 100 investigated participants obtained satisfactory results in the practical performance of BLS. Participants with repeated participation in BLS obtained significantly better results (<b>Group 1: </b>32.7% vs. <b>Group 2: </b>10.4%; p < 0.01) than course participants with no relevant previous knowledge.</p> <p>Conclusion</p> <p>Only 22% of the investigated participants at the end of a "LSM course" were able to perform BLS satisfactorily according to the ERC guidelines. Participants who had previously attended comparable courses obtained significantly better results in the practical test. Through regular repetitions it seems to be possible to achieve, at least on the manikin, an improvement of the results in bystander resuscitation and, consequently, a better patient outcome. To validate this hypothesis further investigations are recommended by specialised societies.</p
