Experts at The University of Nottingham say our stress levels at work peak when we reach about 50 to 55 years of age and decrease as we head towards retirement. In the first comprehensive report into age related stress and health at work to be carried out in Britain researchers from the Institute of Work, Health and Organisations also found that the effects of stress in our working lives can stay with us well into retirement. The research, led by Amanda Griffiths, Professor of Occupational Health Psychology, reviewed hundreds of publications from the last 20 years. Professor Griffiths, said: “Work related stress is thought to be responsible for more lost working days than any other cause and it is becoming clear that it is also one factor affecting older workers’ willingness and ability to remain in the labour force. Therefore, protecting tomorrow’s older workers, as well as today’s, will pay dividends, as older workers will form a major part of tomorrow’s workforce.” Many of us are likely to be working much longer than we expected. Until now the majority of reviews of research into work-related stress – its causes and its effects – have been based on large groups of workers and very rarely distinguished by age. This report, for TAEN – The Age and Employment Network, Age Concern and Help the Aged, aimed to address that gap. This new research suggests that the reason studies show smaller number of workers report high stress levels once in their 50s might be because they have left stressful posts in favour of something less demanding; they already have retired voluntarily or because of ill health; or increasing seniority can give staff more control over their working life which makes it less stressful. The report says this makes older staff the healthy ‘survivors’ of the workplace. Chris Ball, TAEN Chief Executive, said: “This report fills an important gap in our understanding of how stressful work can impact upon people towards the end of their working lives and into retirement. Demographic change and ageing populations have made extending working life a priority both in the UK and elsewhere. Clearly, we have to consider the kind of work people do and every aspect of the working environment with a view to removing stressors where we possibly can. TAEN and our sister charity, Age Concern and Help the Aged, sincerely hope this report will influence thinking and practice, so the casual acceptance of work-created mental ill health, permeating into older age, becomes a thing of the past.” The report suggests that stress could be eased by giving older staff more control over their job; better recognition for the contribution they make; increased flexible working; and improvements in social support. Professor Griffiths said: “As we get older people’s priorities may also change; they often have caring responsibilities, or wish to spend time with grandchildren and develop other interests. Their work and career may not be their primary drivers. Making work attractive and flexible – to allow older people to balance work and their other interests more easily may be one very important step forward”. She suggests that such investments in the quality of people’s ‘third age’ – their life after retirement – should be made during working life, not just afterwards.

Embryos that are most likely to result in a pregnancy are crucial to the success of in vitro fertilization (IVF) but are difficult to identify. Researchers at Yale School of Medicine, led by Emre Seli, M.D., are developing a fast, non-invasive test to help assess embryo viability for IVF. Seli, associate professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale, presented new embryo selection findings at the American Society for Reproductive Medicine (ASRM) meeting held in Atlanta, Georgia. Women undergoing infertility treatment with IVF are hormonally stimulated to produce multiple eggs, which are then fertilized in the lab. In most cases, multiple embryos are generated and cultured. Selecting embryos for implantation is currently highly subjective. “It’s a guessing game that can end in IVF failure or multiple pregnancies,” said Seli. “Our goal is to find a way to pinpoint the embryos with the best chance of success, so that we can transfer fewer embryos and cut down on the possibility of multiple pregnancies without reducing the pregnancy rate.” To detect the difference between a viable and non-viable embryo, Seli and his team have studied the metabolomic profile of spent embryo cultures. A metabolomic profile is the unique chemical fingerprint that results from the metabolic activity of embryos in culture. The team previously found that metabolomic profiling could give an instant snapshot of the physiology of a cell. This non-invasive approach may provide a useful adjunct to the current embryo grading systems based on the structure of the embryo and the rate at which the embryo divides. Building on this groundbreaking finding, Seli and his team have found that a viability score generated by non-invasive assessment of embryo culture media using metabolomics affected pregnancy outcomes in women treated in four different centers in Europe and Australia. This study – performed in collaboration with Molecular Biometrics, Inc. and co-authored by Denny Sakkas, Lucy Botros, Marc Henson and Kevin Judge – was presented at the ASRM meeting. “These findings have important implications for the more than 125,000 IVF cycles performed yearly in the United States,” said Seli. “The high multiple pregnancy rates associated with IVF have significant public health consequences, such as decreased survival and increased risk of lifelong disability associated with severe prematurity.” Seli also received the 2009 Ira and Ester Rosenwaks New Investigator Award on October 18. This prestigious award is given annually by ASRM and recognizes outstanding contributions to research in reproductive sciences by an investigator within the first 10 years of his/her career. The award recognizes Seli’s work in infertility research, identifying novel genes and characterizing key aspects of the regulation of gene expression during early development.

Fever is a common medical sign that describes an increase in internal body temperature to levels above normal. Generally, a fever is an indication of something unusual in the body. It is the body’s response to a disease. In adults, a fever usually is not dangerous unless it reaches 103 F (39.4 C) or higher. In young children and infants, a slightly elevated temperature may be a sign of a serious infection. According to Medilexicon’s medical dictionary, fever is: “A complex physiologic response to disease mediated by pyrogenic cytokines and characterized by a rise in core temperature, generation of acute phase reactants, and activation of immune systems.” The degree of fever is not necessarily related to the seriousness of the underlying condition. There are numerous over-the-counter medications to lower a fever. However, it seems sometimes it is better left untreated. Fever could play an important role in helping the body fight off a number of infections. Fever is considered as one of the body’s immune mechanisms to attempt a neutralization of a perceived threat inside the body (bacterial or viral). The average temperature of the human body is 98.6 F (37 C). Depending on the cause of the fever, symptoms may include: * Dehydration High fevers between 103 F (39.4 C) and 106 F (41.1 C) may cause: * Confusion Fever-induced seizures in children Although alarming, these seizures usually do not cause any lasting effects and are often triggered by a fever from a common childhood illness. Infants An unexplained fever is greater cause for concern in infants and in children than in adults. It is recommended to seek medical advice when a baby has a fever of 101 F (38.3 C) or higher or when: * The baby is younger than 3 months of age. * Infant refuses to eat or drink. * Has a fever and unexplained irritability. Unusual crying during a diaper change or when moved. * Has a fever and seems lethargic and unresponsive. In infants and children younger than age 2, these may be signs of meningitis (an infection and inflammation of the membranes and fluid surrounding the brain and spinal cord). * When a newborn and has a lower than normal temperature. Less than 97 F (36.1 C). Very young babies may not be able to regulate their body temperature when they are ill. They may become cold rather than hot. Children Children usually tolerate fevers well. Parents should not only check temperature measurement but also how the child behaves. There is probably no cause for alarm if the child has a fever but is responsive, drinking fluids, playing, making eye contact and responding to stimuli such as facial expressions and voice. Seek medical advice if the child: * Has a fever after being left in a hot car. Seek medical care immediately. * Has a fever that persists longer than one day in children younger than age 2. Fever lasting longer than three days in children ages 2 and older. * Is lethargic or irritable, vomits repeatedly, has a severe headache or stomachache, or has any other symptoms causing major discomfort. Ask for medical guidance if there are special circumstances (a child with immune system problems or with a pre-existing illness). Sometimes, older children with severe neurological impairments, with a life-threatening bacterial infection in the blood (sepsis) or with suppressed immune systems can have a lower than normal temperature. Adults Seek medical advice if: * Temperature is higher than 103 F (39.4 C) In addition, seek immediate medical attention if a fever appears together with any of these signs or symptoms: * Abdominal pain or pain when urinating What are the causes of fever? The mechanism of body temperature: * Body temperature is set by the hypothalamus which is an area at the base of the brain that acts as a thermostat for the whole system. * Temperature is the balance of the heat produced by the body tissues (particularly the liver and muscles), and the heat the body loses. * During illness, normal temperature may be set a little higher as the body directs blood away from the skin to decrease heat loss. * When a fever starts, the body tries to elevate its temperature. There is a feeling of chilliness and possible shivering. This is to generate heat until the blood around the hypothalamus reaches the new set point. * When temperature begins to return to normal, there may be profuse sweat to get rid of the excess heat. * For the very old, the very young or alcoholic, the body’s ability to produce a fever may be diminished. Usually, a fever indicates the body is responding to a viral or bacterial infection. Other possible causes include: * Certain inflammatory conditions such as rheumatoid arthritis (inflammation of the lining of the joints) * Extreme sunburn * Heat exhaustion * In some rare cases, a malignant tumor or some forms of kidney cancer * Some immunizations, such as the diphtheria, tetanus and acellular pertussis (DTaP) or pneumococcal vaccines (in infants and children) * Some medications, such as antibiotics and drugs used to treat high blood pressure or seizures Sometimes it is impossible to identify the cause of a fever. If a temperature of 101 F (38.3 C) or higher lasts for more than three weeks and it is medically impossible to find the cause after extensive evaluation, the diagnosis may be fever of unknown origin. To confirm a diagnosis, other tests may be required, such as blood tests. In the case of a low-grade fever that persists for three weeks or more, but with no other symptoms, a variety of tests may be recommended to help find the cause. These may include blood tests and X-rays. Antibiotics do not treat viral infections, such as stomach infection and mononucleosis. There are a few antiviral drugs used to treat some specific viral infections. However, the most effctive treatment for most viruses is often rest and plenty of fluids. Over-the-counter medications Over-the-counter medications may be recommended, such as acetaminophen (Tylenol, parecetamol) or ibuprofen (Advil, Motrin) to lower a high fever. Adults also may use aspirin. However, do not give aspirin to children under 16 years of age, because it may trigger a rare, but potentially fatal, disorder known as Reye’s syndrome. Is it wise to lower a fever? In the case of a low-grade fever, it is not advisable to try to lower the temperature. This may extend the illness or mask symptoms and make it more difficult to determine the cause. A number of experts judge that aggressively treating a fever interferes with the body’s immune response. The viruses that cause colds and other respiratory infections thrive at normal body temperature. By producing a low-grade fever, the body may be helping eliminate a virus. Febrile seizures usually involve loss of consciousness and shaking of limbs on both sides of the body. Infrequently, a child may become rigid and convulse only part of his or her body. What to do in case of a febrile seizure? Lay the child on his or her side or stomach on the floor or ground. Remove any sharp objects that are near the child, loosen tight clothing and hold the child to prevent injury. Do not place anything in the child’s mouth or try to stop the seizure. Although most seizures stop on their own, call for emergency medical assistance if a seizure lasts longer than 10 minutes. After the seizure, take the child to the doctor as soon as possible to determine the cause of the fever. Remedies A number of things can be of assistance during a fever: * Drinking plenty of fluids. Drinking water, juices or broth. Fever can cause fluid loss and dehydration. The use an oral rehydration solution (such as Pedialyte) is recommended for a child under age 1. * Resting. It is essential for recovery. Activity can raise body temperature. * Staying cool. Dressing in light and comfortable clothing, keeping the room temperature cool. * Taking acetaminophen or ibuprofen. Use according to the instructions or doctor’s recommendations. High doses or long-term use of acetaminophen may cause liver or kidney damage, and acute overdoses can be fatal. * Soaking in lukewarm water. Particularly in case of high temperatures, a lukewarm five- to 10-minute soak or bath can be cooling. Do not use alcohol. And if the bath causes shivering, stop the bath. Shivering raises the body’s internal temperature (shaking muscles generate heat). Taking a temperature * Temperature in the anus (rectum/rectal) is at or over 100.0 °F (37.8 °C) To check temperature, there are several types of thermometers, including electronic thermometers and ear thermometers. Digital thermometers and those that quickly take temperature from the ear canal are particularly useful for young children and older adults. As glass mercury thermometers may have potential health implications for humans and the environment, they have been discontinued and are no longer recommended. Although not the most accurate way to take a temperature, oral thermometer can be used for an armpit reading: * Place the thermometer in the armpit with arms crossed over the chest. * Wait four to five minutes. The axillary temperature is slightly lower than an oral temperature. * The actual number on the thermometer should be reported to the doctor. Specify where on the body the temperature taken. Use a rectal thermometer for infants: * Place a dab of petroleum jelly on the bulb. * Lay baby on his or her tummy. * Carefully insert the bulb one-half inch to one inch into the baby’s rectum. * Hold the bulb and baby still for three minutes. * Do not let go of the thermometer while it is inside the baby. If the baby moves, the thermometer could go deeper and cause an injury. How to prevent fever? Washing hands often, especially before eating and after using the toilet, after spending time in a crowd or around someone who’s sick, and after petting animals. Show children how to wash their hands properly, lathering both the front and back of each hand with soap, and rinsing carefully under running water. When there is no access to soap and water, carrying moist towelettes or hand sanitizer. When possible, trying not to touch nose, mouth or eyes which are the main way viral infections are transmitted. In addition, adults and children should remember to turn away from others and to cover their mouths when coughing and their noses when sneezing. Written by Stephanie Brunner B.A. |
