Antibiotics to prevent infection of the brain coverings (meningitis) in patients with basilar skull fracture | Cochrane

Basilar skull fracture (7% to 15.8% of all skull fractures) places the central nervous system in contact with bacteria from the nose and throat and may be associated with cerebrospinal fluid leakage (occurring in 2% to 20.8% of patients). Blood or watery discharge from the nose or ears, bruising behind the ear or around the eyes, hearing loss, inability to perceive odours or facial asymmetry may lead physicians to the diagnosis of basilar skull fracture. Patients with a basilar skull fracture may develop meningitis and some doctors give antibiotics in an attempt to reduce this risk.

What Happens When You Forget to Change Your Filter

So you know you’re supposed to change your air filter regularly, generally every three months or even more frequently. But, life happens and often changing filters is something that we store in the back of our minds as we think about day-to-day life—work, kids and our social lives—and we might just forget.So what’s the danger in this? How will forgetting to change your air filter affect you, your family and anyone else who enters your home?Problem #1: You’ll experience a poorer quality of air in your home.Air filters & AC filters works to trap harmful particles like mold, pet dander and bacteria that would otherwise pollute the air in your home. If a filter isn’t changed in due time, it will simply run out of room to collect more of these contaminants.Say you spill some juice. You grab a paper towel and cover the spill. After the first paper towel becomes too saturated to absorb more juice, you throw it away and grab and second one to continue cleaning up the spill. That second paper towel is necessary to keeping your home clean in the same way a new filter is.Problem #2 : Your HVAC system will work less efficiently, or not at all.In short, when you forget to change your air filter, contaminants like pollen and dust clog the filter and keep it from doing its job—cleaning the air that circulates throughout your home. And preventing your filter from doing the work it was deigned to do, not only keeps your HVAC system from doing the same, but also may harm it. and adds up to indoor air pollution which very harmful.Your HVAC system is powered by a fan motor that will have to work harder and harder to push air through a clogged filter. This additional pressure may cause the fan motor to overheat or even break entirely. Replacing a broken HVAC system will cost you—but so will letting an HVAC system run with a dirty filter. More work for the fan motor translates to higher charges on your electric bill. Additionally, a dirty evaporative (cooling) coil can dramatically reduce your airconditioners performance.Problem #3: You’ll inadvertently make your home dirtier.If your air filter becomes too clogged, the dust and dirt particles that it won’t be able to trap will simply recirculate throughout your home. This means dirt will collect quickly on surfaces within your house. Chances are, if you notice you’re dusting more frequently, it’s time to change your filter. No one wants to live in a dirty home, and cleaning more is certainly a pain, but it’s important to remember that the worst part of having more dirt in your home comes from breathing in that dirt. Failing to change your filter means living in an environment that will negatively affect your family’s health—especially if they have allergies, weak immune systems or other medical conditions.Furthermore, failing to change your filter can be negative for the environment as a whole. Remember, how clogged filters make your HVAC system work harder? As they expend more energy, your carbon footprint increases.Though changing your air filter may be an easy task to forget, it’s one that is important for your family’s health. You want to make sure the air they breathe is clean, especially if they suffer from allergies or conditions like asthma. If you need help remembering to change your air filter, try setting an alarm on your phone or marking your digital or paper calendar. Or you might align changing your filter with other important events on your calendar. Find one chore that you do every 3 months or more frequently depending on your needs, and plan to change your filter at the same time. If you’re noticing more dust in your home, or having more trouble with allergies than usual, you can take the hint that perhaps it’s time. When in doubt, just take your air filter out and see how dirty it looks. Changing your filter may be hard to remember, but the good news is, it’s a quick and easy way to improve your quality of life.

Vaccines for preventing severe salmonella infections in people with sickle cell disease | Cochrane

Salmonella organisms are probably second only to pneumococcus among bacterial causes of infection in people with sickle cell disease. Infection with these bacteria can lead to complications and reduce the quality of life of people with the disease and sometimes result in death. Immunization with salmonella vaccines is one of the interventions available to reduce infection by these bacteria. There are different types of vaccines available: the inactivated vaccines and the oral vaccines. We did not find any randomized controlled trials assessing these vaccines in people with sickle cell diseases. We therefore conclude that there is a need for a randomized controlled trial to assess the benefits and risks of the different types of vaccines to evaluate the potential for improving survival and decreasing mortality from salmonella infections in people with sickle cell disease.

Severe combined immunodeficiency

Severe combined immunodeficiency (SCID) represents a group of rare, sometimes fatal, congenital disorders characterized by little or no immune response. The defining feature of SCID, commonly known as "bubble boy" disease, is a defect in the specialized white blood cells (B- and T-lymphocytes) that defend us from infection by viruses, bacteria and fungi. Without a functional immune system, SCID patients are susceptible to recurrent infections such as pneumonia, meningitis and chicken pox, and can die before the first year of life. Though invasive, new treatments such as bone marrow and stem-cell transplantation save as many as 80% of SCID patients.

Antibiotic prophylaxis during the second and third trimester in pregnancy to reduce adverse pregnancy outcomes and morbidity | Cochrane

Antibiotics are administered to pregnant women during the second and third trimester of pregnancy (before labour) to prevent bacteria in the vagina and cervix affecting the pregnancy. Infection by some infectious organisms in a woman’s genital tract can cause health problems for the mother and her baby, and has been associated with preterm births. This review of eight randomised trials involved approximately 4300 women in their second or third trimester. We found that antibiotics did not reduce the risk of preterm prelabour rupture of the membranes (one trial, low quality of evidence), or the risk of preterm birth (six trials, high quality of evidence). Preterm delivery was reduced in pregnant women who had a previous preterm birth and an imbalance of bacteria in the vagina (bacterial vaginosis) during the current pregnancy. There was no reduction in preterm delivery in pregnant women with previous preterm birth without a bacterial imbalance during the current pregnancy (two trials). Postpartum endometritis, or infection of the uterus following birth, was reduced overall (three trials, moderate quality of evidence), as well as in a trial of high-risk women who had a previous preterm birth (one trial, moderate quality of evidence). No reduction in neonatal illness was observed. Outcomes of interest were available in trials with high losses to follow-up. We could not estimate the side effects of antibiotics since side effects were rare; however, antibiotics may still have serious side effects on women and their babies.

Needle size for vaccination procedures in children and adolescents | Cochrane

Vaccines contain antigens that make our immune system produce antibodies that can protect against disease. Antigens are modified or partial forms of the virus, bacteria, or the toxin that cause the disease that the vaccine protects against. Because the antigen is altered from its original form it cannot cause disease, but it can produce an immune response.

Antibiotics for preventing recurrent sore throat | Cochrane

Recurrent sore throat is an inflammation of the throat occurring three or more times per year. Sore throat has many causes, including bacteria, viruses, fungi (uncommonly) and non-infective causes. It causes throat pain, redness, swelling, swollen lymph nodes and symptoms of other accompanying respiratory infections. Antibiotics are sometimes used to prevent recurrent sore throat on the basis that sore throats can be caused by bacteria. However, frequent use of antibiotics has been linked to the development of antibiotic resistance. We looked for studies (randomised controlled trials) that investigated the effectiveness of antibiotics for preventing recurrent sore throat in adults and children.

Mechanisms of Yersinia Pathogenesis | NERCE | BEID

The genus of the Gram negative bacterium Yersinia harbors three species that are mammalian pathogens: Y. pestis, the causative agent of plague, is acquired by the bite of an infected flea, and results from direct inoculation of bacteria into the bloodstream. Two other species, Y. enterocolitica, and Y. pseudotuberculosis, are enteric pathogens and acquired by ingestion of contaminated food or water. Y. pestis is believed to have recently evolved from Y. pseudotuberculosis, while Y. pseudotuberculosis and Y. enterocolitica split from a more ancient common ancestor. All three species are highly lymphotropic, with the property of colonizing and replicating in lymphoid organs. While the precise pathologies of the three species differ in humans (enteric Yersiniae tend to cause self-limiting infections of the intestine and mesenteric lymph nodes, while Y. pestis is a disseminated often fatal systemic infection), all three share a common 70 kB virulence plasmid that encodes the well studied Yersinia Type III secretion system and its secreted effector Yersinia outer proteins (Yops). Oral infection of mice with either Y. enterocolitica or Y. pseudotuberculosis also leads to a disseminated infection and thus is a useful model of systemic yersiniosis. The purpose of the Yops appears to be interference with essential aspects of host immune response and cell biology. For example YopH is a tyrosine phosphatase that disrupts actin cytoskeleton dynamics by interfering with focal adhesion protein complexes. In addition, YopH directly blocks T and B cell activation by dephosphorylating essential signaling proteins at the activated B and T cell receptors.

Interventions for preventing recurrent urinary tract infections during pregnancy | Cochrane

Recurrent urinary tract infections (RUTI) are common in women generally, and particularly in pregnant women. A urinary tract infection (UTI) is an infection of the urinary tract (bladder, kidneys) due to the presence of bacteria in the urine (bacteriuria). During pregnancy, UTI may be a serious complication that is associated with adverse pregnancy outcomes for both mother and child including preterm birth and small-for-gestational-age babies. Therefore, it is important to define the optimal intervention for preventing RUTI during pregnancy to improve pregnancy outcomes. Interventions used to prevent RUTI in pregnant women can be pharmacological (antibiotics) or non-pharmacological (cranberry products, acupuncture, probiotics and behavioural modifications). So far, little is known about the best way to prevent RUTI in pregnant women.
