Having kids causes more relationship conflicts in couples than illnesses or accidents, according to a new study which also found that relationship quality is restored when the kids grow up and move out. Manuela Schicka, along with Eric Widmer, from the University of Geneva in Switzerland, demonstrated that while the various styles of conjugal interactions generally remain stable along the life course, some critical life events and transitions weigh much more on relationship quality than others, sometimes in unexpected ways. Schicka observed 721 heterosexual couples participating in a survey in 1998 and 2011, which generated information on stability and change among couples living in Switzerland. She looked at normative (ie expected and ordinary) transitions like becoming parents, grown children leaving home (the "empty nest" syndrome) and retirement. Researchers also examined non-normative (ie unexpected and unintended) events like socio-professional and health-related problems. To assess relationship quality, they looked at indicators such as relationship satisfaction, thoughts of separation, conflicts of different sorts, and severity of arguments. The styles of conjugal interactions were identified following the typology based on dimensions like cohesion (fusion vs autonomy, openness vs closure) and regulation (level of gendered role differentiation, level of routinisation). The researchers found that couples with a high degree of fusion resisted better to life hazards. They also found that the style of conjugal interactions change very little over the life course. However, some transitions, especially the retirement phase, tend to result in the growth of fusion. This moment in time and the "empty nest" transition appeared as rather beneficial for relationship quality. By contrast, transition to parenthood and socio-professional problems generated more conflicts and a decrease in relationship satisfaction, researchers found. It is also interesting to note that serious illness and injuries do not affect relationship quality. Almost half of the interviewed couples had been confronted to health problems during the study, whereas only 20 per cent faced socio-professional difficulties. Schicka explained that the difference of outcome between work and health related problems by the fact that people are considered as controlling their occupational trajectory, whereas illness and accidents are seen as linked to bad luck and not personal responsibility. It is therefore ironical that the main purpose of matrimonial union, having kids, is a major challenge to couple stability, whereas transitions to the "empty nest" and to retirement succeed in reuniting couples at an age that is generally not perceived as the most romantic one, researchers said.

Scientists have found a novel way to attack the drug resistant bacteria that cause eye infections resulting in blindness. The study led by Daniel Kadouri, an assistant professor of oral biology at the University of Medicine and Dentistry of New Jersey had three major components. The first established that isolates of two antibiotic-resistant ocular pathogens, Pseudomonas aeruginosa and Serratia marcescens, were all susceptible to being attacked and killed by at least one of two other bacteria, Micavibrio aeruginosavorus and Bdellovibrio baceriovorus. The latter two bacteria act as predators against the pathogens but are believed to be "good," or non-infectious, bacteria when they exist within the human body, researchers said. In the second phase, human corneal-limbic epithelial cells that are native to the eye were exposed in vitro to M aeruginosavorus and B baceriovorus to test whether those "good" predator bacteria would cause either toxicity or inflammation in those cells, which they did not. In the third phase, the two "good" predator bacteria were injected into live worms from the species Galleria mellonella, which is well established as a suitable to test the toxicity of various microbes as well as a live organism's innate immunity to those microbes. here injection of the pathogenic bacterium aeruginosa as a positive control was one hundred per cent fatal to the worms, other worms injected with the two "good" predator bacteria had 11-day survival rates between 93.3 and 100 per cent, a strong sign that the "good" bacteria were not toxic to the worms. In addition a lack of change in larval pigmentation following injection suggested that the "good" bacteria also did not provoke an aggressive innate immune response in the worms. "Taken together, our findings leave us confident that, in isolation, pathogenic bacteria are susceptible to successful attack by predator bacteria, predator bacteria do not appear inherently harmful to ocula r cells when applied topically, and a live organism can tolerate the predator bacteria well," said Kadouri. "The time to test all three phenomena simultaneously in the eye tissue of a live organism may now be at hand," Kadouri said.

High heels may cause permanent injury, with most women suffering pain in just over an hour of wearing height-enhancing footwear, a new study has found. Wearing the ill-fitted shoes can cause long-term damage including arthritis, stress fractures, and trapped nerves, which may even require surgery or steroid injections, consultant podiatrist Mike O'Neill warned. Researchers at The College of Podiatry, UK, found that almost half of women have suffered foot problems after wearing an uncomfortable pair of shoes, but 43 per cent will suffer in the name of fashion. One third of women also admitted that they had worn heels they knew did not fit, simply because they "looked nice" - and could not find a pair in their size, The Telegraph reported. On average, high heels start to hurt after 1 hour, 6 minutes and 48 seconds, but a fifth 20 per cent started to feel the pinch within just 10 minutes. As many as 28 per cent women said they have resorted to dancing bare foot in a nightclub or bar when they could not put up with the pain any longer. One third of them admitted to have been forced to remove their shoes and walk home barefoot because they could not bear the pain any longer. The study of 2,000 British adults also found that only 12 per cent of men have put up with stylish but uncomfortable shoes. Researchers said that could explain why women are likely to have more issues with their feet, and are twice as likely to suffer from corns, cracked heels and bunions. A staggering 90 per cent of women have experienced problems and 20 per cent admitted they are "embarrassed" by their feet while 12 per cent are so ashamed they cover them constantly. As many as 19 per cent of women have refused to seek help despite these problems, because they believed their foot complaint was unimportant. Researchers said it appears younger women are more likely to be doing themselves harm as the younger the woman, the higher their heels. 20 per cent of those aged 18 to 24 owned a pair of six inch heels.
