Clindamycin plus gentamicin as expectant therapy for presumed mixed infections. (1/5981)
The prevalence of obligate anaerobes was studied prospectively in 60 patients with severe sepsis of intra-abdominal, soft tissue, female genital or oropulmonary origin. In addition, the efficacy of clindamycin (for anaerobes) plus gentamicin (for aerobic bacteria, especially coliforms) as initial empiric therapy in these patients was evaluated. Among 54 patients with cultural proof of infection, anaerobic pathogens were recovered from 52%. Nineteen patients had bacteremia; Bacteroides fragilis and Klebsiella pneumoniae were the most prevalent pathogens, being isolated in five patients each. Infection was eradicated in 56 of the 60 patients (93%). Mortality related to sepsis was 7% in the entire group, 16% in patients with bacteremia and 2% in patients without bacteremia. Eighty-five percent of aerobic isolates tested were susceptible in vitro to either gentamicin or clindamycin; 97% of anaerobic isolates were inhibited by 5 mug/ml of clindamycin. (+info)Effect of warfarin on the induction and course of experimental endocarditis. (2/5981)
The effect of warfarin treatment on an experimental endocarditis was studied in rabbits. Warfarin had no effect on the induction of a Streptococcus sanguis infection in catheter-induced endocardial vegetations, and the course of this infection was also unaltered. However, warfarin treatment resulted in rapidly progressive bacteremia, probably due to impaired circulation in clearing organs such as the lungs, liver, and spleen. Warfarin also reduced the survival time of the infected rabbits, in which pulmonary edema and extensive lung hemorrhages may have been a contributory factor. (+info)HLA-DR expression and soluble HLA-DR levels in septic patients after trauma. (3/5981)
OBJECTIVE: To determine if cellular and soluble HLA-DR molecules may be relevant in severely injured patients for the development of gram-positive or gram-negative sepsis. SUMMARY BACKGROUND DATA: HLA-DR molecules play a central role in the specific immune response to infection. The reduced HLA-DR expression on monocytes is considered to correlate with infectious complications and the development of sepsis. Data on the role of HLA-DR expression on T cells and soluble HLA-DR molecules are rare. METHODS: HLA-DR expression on monocytes and T cells was measured by flow cytometry. Plasma levels of soluble HLA-DR were studied by enzyme-linked immunosorbent assay. RESULTS: HLA-DR expression on circulating T cells, calculated as mean fluorescence intensity in channels, was reduced at day 1 after admission in 20 patients with subsequent severe sepsis compared with 46 patients without sepsis. The septic patients immediately after trauma had significantly lower soluble HLA-DR plasma levels than the nonseptic patients. At day 2 after admission, HLA-DR expression on monocytes was significantly lower in the severe sepsis group than in the patients without sepsis, and lasted until day 14 after injury. CONCLUSIONS: In severely injured patients, decreased levels of cellular and soluble HLA-DR appear as early indicators of an immune deviation associated with the development of severe sepsis. Moreover, immune alterations of different cell types may promote distinct kinds of septicemia. (+info)Protective effect of bactericidal/permeability-increasing protein (rBPI21) in baboon sepsis is related to its antibacterial, not antiendotoxin, properties. (4/5981)
OBJECTIVE AND SUMMARY BACKGROUND DATA: The recombinant fragment of bactericidal/permeability-increasing protein, rBPI21, has potent bactericidal activity against gram-negative bacteria as well as antiendotoxin (lipopolysaccharide [LPS]) action. On the basis of these activities, the authors sought to discover whether rBPI21 would be protective in baboons with live Escherichia coli-induced sepsis and whether the potential protective effects of rBPI21 (together with antibiotics) would be more closely related to its antibacterial or LPS-neutralizing effects. METHODS: In a prospective, randomized, placebo-controlled subchronic laboratory study, the efficacy of rBPI21 or placebo was studied over 72 hours in chronically instrumented male baboons infused with live E. coli under antibiotic therapy. RESULTS: Intravenous rBPI21 attenuated sepsis-related organ failure and increased survival significantly. Bacteremia was significantly reduced in the rBPI21 group at 2 hours after the start of the E. coli infusion, whereas circulating LPS was less affected. The in vivo formation of tumor necrosis factor was significantly suppressed by the rBPI21 treatment regimen. Microcirculation and organ function were improved. CONCLUSIONS: In baboon live E. coli sepsis, the salutary effect of rBPI21 results from a more prevalent antibacterial than antiendotoxin activity. (+info)A sustained rat model for studying the long-lasting catabolic state of sepsis. (5/5981)
Most animal models of sepsis induced high mortality or early recovery and do not mimic the long-lasting catabolic state observed in patients. The purpose of this study is to develop a model of sepsis which reproduces these disorders, especially the long-lasting muscle wasting. This report summarizes our observations in a series of seven experiments using this model with rats to study the route of live Escherichia coli administration, dose of bacteria, reproducibility of the model, bacterial count in tissues, comparison of injection of live or dead bacteria, metabolic perturbations linked to infection, and potential role of tumor necrosis factor alpha (TNF-alpha) in muscle wasting. After intravenous infection, animals were anorexic and the catabolic state was long-lasting: body weight loss for 2 to 3 days followed by a chronic wasting state for several days. Liver, spleen, lung protein content, and plasma concentration of alpha2-macroglobulin were increased 2 and 6 days after infection. At 6 days, muscle protein content was substantially (-40%) reduced. The plasma TNF-alpha level measured 1.5 h after infection correlated with body weight loss observed 9 days later. The inhibition of TNF-alpha secretion by administration of pentoxifylline 1 h before infection reduced muscle wasting and activation of proteolysis at day 2 and abolished them at day 6. This septic model mimics in rats the prolonged protein metabolism alterations and muscle atrophy characteristics of infected patients and thus is useful for studying the impact of nutritional support on outcome. (+info)Early death during chemotherapy in patients with small-cell lung cancer: derivation of a prognostic index for toxic death and progression. (6/5981)
Based on an increased frequency of early death (death within the first treatment cycle) in our two latest randomized trials of combination chemotherapy in small-cell lung cancer (SCLC), we wanted to identify patients at risk of early non-toxic death (ENTD) and early toxic death (ETD). Data were stored in a database and logistic regression analyses were performed to identify predictive factors for early death. During the first cycle, 118 out of 937 patients (12.6%) died. In 38 patients (4%), the cause of death was sepsis. Significant risk factors were age, performance status (PS), lactate dehydrogenase (LDH) and treatment with epipodophyllotoxins and platinum in the first cycle (EP). Risk factors for ENTD were age, PS and LDH. Extensive stage had a hazard ratio of 1.9 (P = 0.07). Risk factors for ETD were EP, PS and LDH, whereas age and stage were not. For EP, the hazard ratio was as high as 6.7 (P = 0.0001). We introduced a simple prognostic algorithm including performance status, LDH and age. Using a prognostic algorithm to exclude poor-risk patients from trials, we could minimize early death, improve long-term survival and increase the survival differences between different regimens. We suggest that other groups evaluate our algorithm and exclude poor prognosis patients from trials of dose intensification. (+info)Septicemia in dialysis patients: incidence, risk factors, and prognosis. (7/5981)
BACKGROUND: Infection is second to cardiovascular disease as a cause of death in patients with end-stage renal disease (ESRD), and septicemia causes a majority of these infectious deaths. To identify patients at high risk and to characterize modifiable risk factors for septicemia, we examined the incidence, risk factors, and prognosis for septicemia in a large, representative group of U.S. dialysis patients. METHODS: We conducted a longitudinal cohort study of incident ESRD patients in the case-mix study of the U.S. Renal Data System with seven years of follow-up from hospitalization and death records. Poisson regression was used to examine independent risk factors for hospital-managed septicemia. Cox proportional hazards analysis was used to assess the independent effect of septicemia on all-cause mortality and on death from septicemia. Separate analyses were performed for patients on peritoneal dialysis (PD) and hemodialysis (HD). RESULTS: Over seven years of follow-up, 11.7% of 4005 HD patients and 9.4% of 913 PD patients had at least one episode of septicemia. Older age and diabetes were independent risk factors for septicemia in all patients. Among HD patients, low serum albumin, temporary vascular access, and dialyzer reuse were also associated with increased risk. Among PD patients, white race and having no health insurance at dialysis initiation were also risk factors. Patients with septicemia had twice the risk of death from any cause and a fivefold to ninefold increased risk of death from septicemia. CONCLUSIONS: Septicemia, which carries a marked increased risk of death, occurs frequently in patients on PD as well as HD. Early referral to a nephrologist, improving nutrition, and avoiding temporary vascular access may decrease the incidence of septicemia. Further study of how race, insurance status, and dialyzer reuse can contribute to the risk of septicemia among ESRD patients is indicated. (+info)Characteristics of a strain of Clostridium carnis causing septicaemia in a young infant. (8/5981)
Clostridium carnis is a species which is only rarely isolated from man or animals and is occasionally found in the soil. This paper is an account of a single isolate found in blood cultures obtained from an 8-week-old boy who was suffering from gastroenteritis. (+info)Sepsis is a life-threatening condition that arises when the body's response to an infection injures its own tissues and organs. It is characterized by a whole-body inflammatory state (systemic inflammation) that can lead to blood clotting issues, tissue damage, and multiple organ failure.
Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Infections that lead to sepsis most often start in the lungs, urinary tract, skin, or gastrointestinal tract.
Sepsis is a medical emergency. If you suspect sepsis, seek immediate medical attention. Early recognition and treatment of sepsis are crucial to improve outcomes. Treatment usually involves antibiotics, intravenous fluids, and may require oxygen, medication to raise blood pressure, and corticosteroids. In severe cases, surgery may be required to clear the infection.
Septic shock is a serious condition that occurs as a complication of an infection that has spread throughout the body. It's characterized by a severe drop in blood pressure and abnormalities in cellular metabolism, which can lead to organ failure and death if not promptly treated.
In septic shock, the immune system overreacts to an infection, releasing an overwhelming amount of inflammatory chemicals into the bloodstream. This leads to widespread inflammation, blood vessel dilation, and leaky blood vessels, which can cause fluid to leak out of the blood vessels and into surrounding tissues. As a result, the heart may not be able to pump enough blood to vital organs, leading to organ failure.
Septic shock is often caused by bacterial infections, but it can also be caused by fungal or viral infections. It's most commonly seen in people with weakened immune systems, such as those who have recently undergone surgery, have chronic medical conditions, or are taking medications that suppress the immune system.
Prompt diagnosis and treatment of septic shock is critical to prevent long-term complications and improve outcomes. Treatment typically involves aggressive antibiotic therapy, intravenous fluids, vasopressors to maintain blood pressure, and supportive care in an intensive care unit (ICU).
Systemic Inflammatory Response Syndrome (SIRS) is not a specific disease, but rather a systemic response to various insults or injuries within the body. It is defined as a combination of clinical signs that indicate a widespread inflammatory response in the body. According to the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) consensus criteria, SIRS is characterized by the presence of at least two of the following conditions:
1. Body temperature >38°C (100.4°F) or 90 beats per minute
3. Respiratory rate >20 breaths per minute or arterial carbon dioxide tension (PaCO2) 12,000 cells/mm3, 10% bands (immature white blood cells)
SIRS can be caused by various factors, including infections (sepsis), trauma, burns, pancreatitis, and immune-mediated reactions. Prolonged SIRS may lead to organ dysfunction and failure, which can progress to severe sepsis or septic shock if not treated promptly and effectively.
The cecum is the first part of the large intestine, located at the junction of the small and large intestines. It is a pouch-like structure that connects to the ileum (the last part of the small intestine) and the ascending colon (the first part of the large intestine). The cecum is where the appendix is attached. Its function is to absorb water and electrolytes, and it also serves as a site for the fermentation of certain types of dietary fiber by gut bacteria. However, the exact functions of the cecum are not fully understood.
A puncture, in medical terms, refers to a small hole or wound that is caused by a sharp object penetrating the skin or other body tissues. This can result in damage to underlying structures such as blood vessels, nerves, or organs, and may lead to complications such as bleeding, infection, or inflammation.
Punctures can occur accidentally, such as from stepping on a nail or getting pricked by a needle, or they can be inflicted intentionally, such as during medical procedures like injections or blood draws. In some cases, puncture wounds may require medical attention to clean and close the wound, prevent infection, and promote healing.
Multiple Organ Failure (MOF) is a severe condition characterized by the dysfunction or failure of more than one organ system in the body. It often occurs as a result of serious illness, trauma, or infection, such as sepsis. The organs that commonly fail include the lungs, kidneys, liver, and heart. This condition can lead to significant morbidity and mortality if not promptly diagnosed and treated.
The definition of MOF has evolved over time, but a widely accepted one is the "Sequential Organ Failure Assessment" (SOFA) score, which evaluates six organ systems: respiratory, coagulation, liver, cardiovascular, renal, and neurologic. A SOFA score of 10 or more indicates MOF, and a higher score is associated with worse outcomes.
MOF can be classified as primary or secondary. Primary MOF occurs when the initial insult directly causes organ dysfunction, such as in severe trauma or septic shock. Secondary MOF occurs when the initial injury or illness has been controlled, but organ dysfunction develops later due to ongoing inflammation and other factors.
Early recognition and aggressive management of MOF are crucial for improving outcomes. Treatment typically involves supportive care, such as mechanical ventilation, dialysis, and medication to support cardiovascular function. In some cases, surgery or other interventions may be necessary to address the underlying cause of organ dysfunction.
Bacteremia is the presence of bacteria in the bloodstream. It is a medical condition that occurs when bacteria from another source, such as an infection in another part of the body, enter the bloodstream. Bacteremia can cause symptoms such as fever, chills, and rapid heart rate, and it can lead to serious complications such as sepsis if not treated promptly with antibiotics.
Bacteremia is often a result of an infection elsewhere in the body that allows bacteria to enter the bloodstream. This can happen through various routes, such as during medical procedures, intravenous (IV) drug use, or from infected wounds or devices that come into contact with the bloodstream. In some cases, bacteremia may also occur without any obvious source of infection.
It is important to note that not all bacteria in the bloodstream cause harm, and some people may have bacteria in their blood without showing any symptoms. However, if bacteria in the bloodstream multiply and cause an immune response, it can lead to bacteremia and potentially serious complications.
An Intensive Care Unit (ICU) is a specialized hospital department that provides continuous monitoring and advanced life support for critically ill patients. The ICU is equipped with sophisticated technology and staffed by highly trained healthcare professionals, including intensivists, nurses, respiratory therapists, and other specialists.
Patients in the ICU may require mechanical ventilation, invasive monitoring, vasoactive medications, and other advanced interventions due to conditions such as severe infections, trauma, cardiac arrest, respiratory failure, or post-surgical complications. The goal of the ICU is to stabilize patients' condition, prevent further complications, and support organ function while the underlying illness is treated.
ICUs may be organized into different units based on the type of care provided, such as medical, surgical, cardiac, neurological, or pediatric ICUs. The length of stay in the ICU can vary widely depending on the patient's condition and response to treatment.
Endotoxemia is a medical condition characterized by the presence of endotoxins in the bloodstream. Endotoxins are toxic substances that are found in the cell walls of certain types of bacteria, particularly gram-negative bacteria. They are released into the circulation when the bacteria die or multiply, and can cause a variety of symptoms such as fever, inflammation, low blood pressure, and organ failure.
Endotoxemia is often seen in patients with severe bacterial infections, sepsis, or septic shock. It can also occur after certain medical procedures, such as surgery or dialysis, that may allow bacteria from the gut to enter the bloodstream. In some cases, endotoxemia may be a result of a condition called "leaky gut syndrome," in which the lining of the intestines becomes more permeable, allowing endotoxins and other harmful substances to pass into the bloodstream.
Endotoxemia can be diagnosed through various tests, including blood cultures, measurement of endotoxin levels in the blood, and assessment of inflammatory markers such as c-reactive protein (CRP) and procalcitonin (PCT). Treatment typically involves antibiotics to eliminate the underlying bacterial infection, as well as supportive care to manage symptoms and prevent complications.
Ligation, in the context of medical terminology, refers to the process of tying off a part of the body, usually blood vessels or tissue, with a surgical suture or another device. The goal is to stop the flow of fluids such as blood or other substances within the body. It is commonly used during surgeries to control bleeding or to block the passage of fluids, gases, or solids in various parts of the body.
A critical illness is a serious condition that has the potential to cause long-term or permanent disability, or even death. It often requires intensive care and life support from medical professionals. Critical illnesses can include conditions such as:
1. Heart attack
2. Stroke
3. Organ failure (such as kidney, liver, or lung)
4. Severe infections (such as sepsis)
5. Coma or brain injury
6. Major trauma
7. Cancer that has spread to other parts of the body
These conditions can cause significant physical and emotional stress on patients and their families, and often require extensive medical treatment, rehabilitation, and long-term care. Critical illness insurance is a type of insurance policy that provides financial benefits to help cover the costs associated with treating these serious medical conditions.
"APACHE" stands for "Acute Physiology And Chronic Health Evaluation." It is a system used to assess the severity of illness in critically ill patients and predict their risk of mortality. The APACHE score is calculated based on various physiological parameters, such as heart rate, blood pressure, temperature, respiratory rate, and laboratory values, as well as age and chronic health conditions.
There are different versions of the APACHE system, including APACHE II, III, and IV, each with its own set of variables and scoring system. The most commonly used version is APACHE II, which includes 12 physiological variables measured during the first 24 hours of ICU admission, as well as age and chronic health points.
The APACHE score is widely used in research and clinical settings to compare the severity of illness and outcomes between different patient populations, evaluate the effectiveness of treatments and interventions, and make informed decisions about resource allocation and triage.
Calcitonin is a hormone that is produced and released by the parafollicular cells (also known as C cells) of the thyroid gland. It plays a crucial role in regulating calcium homeostasis in the body. Specifically, it helps to lower elevated levels of calcium in the blood by inhibiting the activity of osteoclasts, which are bone cells that break down bone tissue and release calcium into the bloodstream. Calcitonin also promotes the uptake of calcium in the bones and increases the excretion of calcium in the urine.
Calcitonin is typically released in response to high levels of calcium in the blood, and its effects help to bring calcium levels back into balance. In addition to its role in calcium regulation, calcitonin may also have other functions in the body, such as modulating immune function and reducing inflammation.
Clinically, synthetic forms of calcitonin are sometimes used as a medication to treat conditions related to abnormal calcium levels, such as hypercalcemia (high blood calcium) or osteoporosis. Calcitonin can be administered as an injection, nasal spray, or oral tablet, depending on the specific formulation and intended use.
Lipopolysaccharides (LPS) are large molecules found in the outer membrane of Gram-negative bacteria. They consist of a hydrophilic polysaccharide called the O-antigen, a core oligosaccharide, and a lipid portion known as Lipid A. The Lipid A component is responsible for the endotoxic activity of LPS, which can trigger a powerful immune response in animals, including humans. This response can lead to symptoms such as fever, inflammation, and septic shock, especially when large amounts of LPS are introduced into the bloodstream.
A newborn infant is a baby who is within the first 28 days of life. This period is also referred to as the neonatal period. Newborns require specialized care and attention due to their immature bodily systems and increased vulnerability to various health issues. They are closely monitored for signs of well-being, growth, and development during this critical time.
Peritonitis is a medical condition characterized by inflammation of the peritoneum, which is the serous membrane that lines the inner wall of the abdominal cavity and covers the abdominal organs. The peritoneum has an important role in protecting the abdominal organs and providing a smooth surface for them to move against each other.
Peritonitis can occur as a result of bacterial or fungal infection, chemical irritation, or trauma to the abdomen. The most common cause of peritonitis is a rupture or perforation of an organ in the abdominal cavity, such as the appendix, stomach, or intestines, which allows bacteria from the gut to enter the peritoneal cavity.
Symptoms of peritonitis may include abdominal pain and tenderness, fever, nausea and vomiting, loss of appetite, and decreased bowel movements. In severe cases, peritonitis can lead to sepsis, a life-threatening condition characterized by widespread inflammation throughout the body.
Treatment for peritonitis typically involves antibiotics to treat the infection, as well as surgical intervention to repair any damage to the abdominal organs and remove any infected fluid or tissue from the peritoneal cavity. In some cases, a temporary or permanent drain may be placed in the abdomen to help remove excess fluid and promote healing.
Bacterial infections are caused by the invasion and multiplication of bacteria in or on tissues of the body. These infections can range from mild, like a common cold, to severe, such as pneumonia, meningitis, or sepsis. The symptoms of a bacterial infection depend on the type of bacteria invading the body and the area of the body that is affected.
Bacteria are single-celled microorganisms that can live in many different environments, including in the human body. While some bacteria are beneficial to humans and help with digestion or protect against harmful pathogens, others can cause illness and disease. When bacteria invade the body, they can release toxins and other harmful substances that damage tissues and trigger an immune response.
Bacterial infections can be treated with antibiotics, which work by killing or inhibiting the growth of bacteria. However, it is important to note that misuse or overuse of antibiotics can lead to antibiotic resistance, making treatment more difficult. It is also essential to complete the full course of antibiotics as prescribed, even if symptoms improve, to ensure that all bacteria are eliminated and reduce the risk of recurrence or development of antibiotic resistance.
A "newborn infant" refers to a baby in the first 28 days of life outside of the womb. This period is crucial for growth and development, but also poses unique challenges as the infant's immune system is not fully developed, making them more susceptible to various diseases.
"Newborn diseases" are health conditions that specifically affect newborn infants. These can be categorized into three main types:
1. Congenital disorders: These are conditions that are present at birth and may be inherited or caused by factors such as infection, exposure to harmful substances during pregnancy, or chromosomal abnormalities. Examples include Down syndrome, congenital heart defects, and spina bifida.
2. Infectious diseases: Newborn infants are particularly vulnerable to infections due to their immature immune systems. Common infectious diseases in newborns include sepsis (bloodstream infection), pneumonia, and meningitis. These can be acquired from the mother during pregnancy or childbirth, or from the environment after birth.
3. Developmental disorders: These are conditions that affect the normal growth and development of the newborn infant. Examples include cerebral palsy, intellectual disabilities, and vision or hearing impairments.
It is important to note that many newborn diseases can be prevented or treated with appropriate medical care, including prenatal care, proper hygiene practices, and timely vaccinations. Regular check-ups and monitoring of the newborn's health by a healthcare provider are essential for early detection and management of any potential health issues.
Protein C is a vitamin K-dependent protease that functions as an important regulator of coagulation and inflammation. It is a plasma protein produced in the liver that, when activated, degrades clotting factors Va and VIIIa to limit thrombus formation and prevent excessive blood clotting. Protein C also has anti-inflammatory properties by inhibiting the release of pro-inflammatory cytokines and reducing endothelial cell activation. Inherited or acquired deficiencies in Protein C can lead to an increased risk of thrombosis, a condition characterized by abnormal blood clot formation within blood vessels.
Burns are injuries to tissues caused by heat, electricity, chemicals, friction, or radiation. They are classified based on their severity:
1. First-degree burns (superficial burns) affect only the outer layer of skin (epidermis), causing redness, pain, and swelling.
2. Second-degree burns (partial-thickness burns) damage both the epidermis and the underlying layer of skin (dermis). They result in redness, pain, swelling, and blistering.
3. Third-degree burns (full-thickness burns) destroy the entire depth of the skin and can also damage underlying muscles, tendons, and bones. These burns appear white or blackened and charred, and they may be painless due to destroyed nerve endings.
Immediate medical attention is required for second-degree and third-degree burns, as well as for large area first-degree burns, to prevent infection, manage pain, and ensure proper healing. Treatment options include wound care, antibiotics, pain management, and possibly skin grafting or surgery in severe cases.
Gram-negative bacterial infections refer to illnesses or diseases caused by Gram-negative bacteria, which are a group of bacteria that do not retain crystal violet dye during the Gram staining procedure used in microbiology. This characteristic is due to the structure of their cell walls, which contain a thin layer of peptidoglycan and an outer membrane composed of lipopolysaccharides (LPS), proteins, and phospholipids.
The LPS component of the outer membrane is responsible for the endotoxic properties of Gram-negative bacteria, which can lead to severe inflammatory responses in the host. Common Gram-negative bacterial pathogens include Escherichia coli (E. coli), Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, and Proteus mirabilis, among others.
Gram-negative bacterial infections can cause a wide range of clinical syndromes, such as pneumonia, urinary tract infections, bloodstream infections, meningitis, and soft tissue infections. The severity of these infections can vary from mild to life-threatening, depending on the patient's immune status, the site of infection, and the virulence of the bacterial strain.
Effective antibiotic therapy is crucial for treating Gram-negative bacterial infections, but the increasing prevalence of multidrug-resistant strains has become a significant global health concern. Therefore, accurate diagnosis and appropriate antimicrobial stewardship are essential to ensure optimal patient outcomes and prevent further spread of resistance.
Animal disease models are specialized animals, typically rodents such as mice or rats, that have been genetically engineered or exposed to certain conditions to develop symptoms and physiological changes similar to those seen in human diseases. These models are used in medical research to study the pathophysiology of diseases, identify potential therapeutic targets, test drug efficacy and safety, and understand disease mechanisms.
The genetic modifications can include knockout or knock-in mutations, transgenic expression of specific genes, or RNA interference techniques. The animals may also be exposed to environmental factors such as chemicals, radiation, or infectious agents to induce the disease state.
Examples of animal disease models include:
1. Mouse models of cancer: Genetically engineered mice that develop various types of tumors, allowing researchers to study cancer initiation, progression, and metastasis.
2. Alzheimer's disease models: Transgenic mice expressing mutant human genes associated with Alzheimer's disease, which exhibit amyloid plaque formation and cognitive decline.
3. Diabetes models: Obese and diabetic mouse strains like the NOD (non-obese diabetic) or db/db mice, used to study the development of type 1 and type 2 diabetes, respectively.
4. Cardiovascular disease models: Atherosclerosis-prone mice, such as ApoE-deficient or LDLR-deficient mice, that develop plaque buildup in their arteries when fed a high-fat diet.
5. Inflammatory bowel disease models: Mice with genetic mutations affecting intestinal barrier function and immune response, such as IL-10 knockout or SAMP1/YitFc mice, which develop colitis.
Animal disease models are essential tools in preclinical research, but it is important to recognize their limitations. Differences between species can affect the translatability of results from animal studies to human patients. Therefore, researchers must carefully consider the choice of model and interpret findings cautiously when applying them to human diseases.
Prospective studies, also known as longitudinal studies, are a type of cohort study in which data is collected forward in time, following a group of individuals who share a common characteristic or exposure over a period of time. The researchers clearly define the study population and exposure of interest at the beginning of the study and follow up with the participants to determine the outcomes that develop over time. This type of study design allows for the investigation of causal relationships between exposures and outcomes, as well as the identification of risk factors and the estimation of disease incidence rates. Prospective studies are particularly useful in epidemiology and medical research when studying diseases with long latency periods or rare outcomes.
High Mobility Group Box 1 (HMGB1) protein is a non-histone chromosomal protein that is widely expressed in various cell types, including immune cells and nucleated cells. It plays a crucial role in the maintenance of nucleosome structure and stability, regulation of gene transcription, and DNA replication and repair. HMGB1 can be actively secreted by activated immune cells or passively released from necrotic or damaged cells. Once outside the cell, it functions as a damage-associated molecular pattern (DAMP) molecule that binds to various receptors, such as Toll-like receptors and the receptor for advanced glycation end products (RAGE), on immune cells, leading to the activation of inflammatory responses and the induction of innate and adaptive immunity. HMGB1 has been implicated in various physiological and pathological processes, including inflammation, infection, autoimmunity, cancer, and neurological disorders.
Anti-bacterial agents, also known as antibiotics, are a type of medication used to treat infections caused by bacteria. These agents work by either killing the bacteria or inhibiting their growth and reproduction. There are several different classes of anti-bacterial agents, including penicillins, cephalosporins, fluoroquinolones, macrolides, and tetracyclines, among others. Each class of antibiotic has a specific mechanism of action and is used to treat certain types of bacterial infections. It's important to note that anti-bacterial agents are not effective against viral infections, such as the common cold or flu. Misuse and overuse of antibiotics can lead to antibiotic resistance, which is a significant global health concern.
Cytokines are a broad and diverse category of small signaling proteins that are secreted by various cells, including immune cells, in response to different stimuli. They play crucial roles in regulating the immune response, inflammation, hematopoiesis, and cellular communication.
Cytokines mediate their effects by binding to specific receptors on the surface of target cells, which triggers intracellular signaling pathways that ultimately result in changes in gene expression, cell behavior, and function. Some key functions of cytokines include:
1. Regulating the activation, differentiation, and proliferation of immune cells such as T cells, B cells, natural killer (NK) cells, and macrophages.
2. Coordinating the inflammatory response by recruiting immune cells to sites of infection or tissue damage and modulating their effector functions.
3. Regulating hematopoiesis, the process of blood cell formation in the bone marrow, by controlling the proliferation, differentiation, and survival of hematopoietic stem and progenitor cells.
4. Modulating the development and function of the nervous system, including neuroinflammation, neuroprotection, and neuroregeneration.
Cytokines can be classified into several categories based on their structure, function, or cellular origin. Some common types of cytokines include interleukins (ILs), interferons (IFNs), tumor necrosis factors (TNFs), chemokines, colony-stimulating factors (CSFs), and transforming growth factors (TGFs). Dysregulation of cytokine production and signaling has been implicated in various pathological conditions, such as autoimmune diseases, chronic inflammation, cancer, and neurodegenerative disorders.
Critical care, also known as intensive care, is a medical specialty that deals with the diagnosis and management of life-threatening conditions that require close monitoring and organ support. Critical care medicine is practiced in critical care units (ICUs) or intensive care units of hospitals. The goal of critical care is to prevent further deterioration of the patient's condition, to support failing organs, and to treat any underlying conditions that may have caused the patient to become critically ill.
Critical care involves a multidisciplinary team approach, including intensivists (specialist doctors trained in critical care), nurses, respiratory therapists, pharmacists, and other healthcare professionals. The care provided in the ICU is highly specialized and often involves advanced medical technology such as mechanical ventilation, dialysis, and continuous renal replacement therapy.
Patients who require critical care may have a wide range of conditions, including severe infections, respiratory failure, cardiovascular instability, neurological emergencies, and multi-organ dysfunction syndrome (MODS). Critical care is an essential component of modern healthcare and has significantly improved the outcomes of critically ill patients.
Endotoxins are toxic substances that are associated with the cell walls of certain types of bacteria. They are released when the bacterial cells die or divide, and can cause a variety of harmful effects in humans and animals. Endotoxins are made up of lipopolysaccharides (LPS), which are complex molecules consisting of a lipid and a polysaccharide component.
Endotoxins are particularly associated with gram-negative bacteria, which have a distinctive cell wall structure that includes an outer membrane containing LPS. These toxins can cause fever, inflammation, and other symptoms when they enter the bloodstream or other tissues of the body. They are also known to play a role in the development of sepsis, a potentially life-threatening condition characterized by a severe immune response to infection.
Endotoxins are resistant to heat, acid, and many disinfectants, making them difficult to eliminate from contaminated environments. They can also be found in a variety of settings, including hospitals, industrial facilities, and agricultural operations, where they can pose a risk to human health.
Streptococcus agalactiae, also known as Group B Streptococcus (GBS), is a type of bacteria that commonly colonizes the gastrointestinal and genitourinary tracts of humans. It is Gram-positive, facultatively anaerobic, and forms chains when viewed under the microscope.
While S. agalactiae can be carried asymptomatically by many adults, it can cause serious infections in newborns, pregnant women, elderly individuals, and people with weakened immune systems. In newborns, GBS can lead to sepsis, pneumonia, and meningitis, which can result in long-term health complications or even be fatal if left untreated.
Pregnant women are often screened for GBS colonization during the third trimester of pregnancy, and those who test positive may receive intrapartum antibiotics to reduce the risk of transmission to their newborns during delivery.
Puerperal infection, also known as childbed fever or postpartum infection, is a healthcare-associated infection that can occur in women following childbirth, miscarriage, or abortion. It's typically caused by bacteria that enter the reproductive system during these processes and can lead to inflammation and infection of the uterus, fallopian tubes, ovaries, or other pelvic organs.
The most common causative agents are Streptococcus pyogenes (Group A streptococcus), Staphylococcus aureus, and Escherichia coli. Symptoms of puerperal infection can include fever, abdominal pain, foul-smelling vaginal discharge, and painful urination. If left untreated, the infection can lead to serious complications such as sepsis, infertility, or even death.
Prompt diagnosis and treatment with antibiotics are crucial for managing puerperal infections and preventing complications. Good hygiene practices and proper sterilization of medical equipment can also help reduce the risk of developing this infection.
A biological marker, often referred to as a biomarker, is a measurable indicator that reflects the presence or severity of a disease state, or a response to a therapeutic intervention. Biomarkers can be found in various materials such as blood, tissues, or bodily fluids, and they can take many forms, including molecular, histologic, radiographic, or physiological measurements.
In the context of medical research and clinical practice, biomarkers are used for a variety of purposes, such as:
1. Diagnosis: Biomarkers can help diagnose a disease by indicating the presence or absence of a particular condition. For example, prostate-specific antigen (PSA) is a biomarker used to detect prostate cancer.
2. Monitoring: Biomarkers can be used to monitor the progression or regression of a disease over time. For instance, hemoglobin A1c (HbA1c) levels are monitored in diabetes patients to assess long-term blood glucose control.
3. Predicting: Biomarkers can help predict the likelihood of developing a particular disease or the risk of a negative outcome. For example, the presence of certain genetic mutations can indicate an increased risk for breast cancer.
4. Response to treatment: Biomarkers can be used to evaluate the effectiveness of a specific treatment by measuring changes in the biomarker levels before and after the intervention. This is particularly useful in personalized medicine, where treatments are tailored to individual patients based on their unique biomarker profiles.
It's important to note that for a biomarker to be considered clinically valid and useful, it must undergo rigorous validation through well-designed studies, including demonstrating sensitivity, specificity, reproducibility, and clinical relevance.
Hypotension is a medical term that refers to abnormally low blood pressure, usually defined as a systolic blood pressure less than 90 millimeters of mercury (mm Hg) or a diastolic blood pressure less than 60 mm Hg. Blood pressure is the force exerted by the blood against the walls of the blood vessels as the heart pumps blood.
Hypotension can cause symptoms such as dizziness, lightheadedness, weakness, and fainting, especially when standing up suddenly. In severe cases, hypotension can lead to shock, which is a life-threatening condition characterized by multiple organ failure due to inadequate blood flow.
Hypotension can be caused by various factors, including certain medications, medical conditions such as heart disease, endocrine disorders, and dehydration. It is important to seek medical attention if you experience symptoms of hypotension, as it can indicate an underlying health issue that requires treatment.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Blood pressure is the force exerted by circulating blood on the walls of the blood vessels. It is measured in millimeters of mercury (mmHg) and is given as two figures:
1. Systolic pressure: This is the pressure when the heart pushes blood out into the arteries.
2. Diastolic pressure: This is the pressure when the heart rests between beats, allowing it to fill with blood.
Normal blood pressure for adults is typically around 120/80 mmHg, although this can vary slightly depending on age, sex, and other factors. High blood pressure (hypertension) is generally considered to be a reading of 130/80 mmHg or higher, while low blood pressure (hypotension) is usually defined as a reading below 90/60 mmHg. It's important to note that blood pressure can fluctuate throughout the day and may be affected by factors such as stress, physical activity, and medication use.
Urination, also known as micturition, is the physiological process of excreting urine from the urinary bladder through the urethra. It is a complex process that involves several systems in the body, including the urinary system, nervous system, and muscular system.
In medical terms, urination is defined as the voluntary or involuntary discharge of urine from the urethra, which is the final pathway for the elimination of waste products from the body. The process is regulated by a complex interplay between the detrusor muscle of the bladder, the internal and external sphincters of the urethra, and the nervous system.
During urination, the detrusor muscle contracts, causing the bladder to empty, while the sphincters relax to allow the urine to flow through the urethra and out of the body. The nervous system plays a crucial role in coordinating these actions, with sensory receptors in the bladder sending signals to the brain when it is time to urinate.
Urination is essential for maintaining the balance of fluids and electrolytes in the body, as well as eliminating waste products such as urea, creatinine, and other metabolic byproducts. Abnormalities in urination can indicate underlying medical conditions, such as urinary tract infections, bladder dysfunction, or neurological disorders.
A foreign-body reaction is an immune response that occurs when a non-native substance, or "foreign body," is introduced into the human body. This can include things like splinters, surgical implants, or even injected medications. The immune system recognizes these substances as foreign and mounts a response to try to eliminate them.
The initial response to a foreign body is often an acute inflammatory reaction, characterized by the release of chemical mediators that cause vasodilation, increased blood flow, and the migration of white blood cells to the site. This can result in symptoms such as redness, swelling, warmth, and pain.
If the foreign body is not eliminated, a chronic inflammatory response may develop, which can lead to the formation of granulation tissue, fibrosis, and encapsulation of the foreign body. In some cases, this reaction can cause significant tissue damage or impede proper healing.
It's worth noting that not all foreign bodies necessarily elicit a strong immune response. The nature and size of the foreign body, as well as its location in the body, can all influence the severity of the reaction.

- With three good case scenarios, Dr. Kritek explained how it was difficult to accurately diagnose sepsis using the Sepsis-2/SIRS criterion, and how the SIRS criterion led to several false positives. (the-hospitalist.org)
Inflammatory5
- These aforesigns are used to identify systemic inflammatory response syndrome that only becomes sepsis when presence of sepsis is there. (selfgrowth.com)
- In Gram-negative bacterial sepsis, production of excess pro-inflammatory cytokines results in hyperinflammation and tissue injury. (nature.com)
- Inflammatory mediators play a critical role in the pathogenesis and potential management of intra-abdominal sepsis. (nature.com)
- Sepsis can be considered in individuals with systemic inflammatory response syndrome (SIRS) manifested by alterations in at least two of temperature, heart rate, respiratory rate, and/or white blood cell count. (aacc.org)
- In so doing it indirectly addresses a major concern expressed over the new Sepsis-3 definitions: Will abandoning the systemic inflammatory response syndrome (SIRS) criteria delay the identification of sepsis? (medscape.com)
Pediatric3
- We present data from 1995, 2000, and 2005 in seven U.S. states, examining how case mix, outcome, and resource use for pediatric severe sepsis have changed over time. (nih.gov)
- there was an 81% increase in pediatric severe sepsis cases since 1995 and a 45% increase since 2000. (nih.gov)
- Nationally, there were 75,255 pediatric hospitalizations in 2005 involving severe sepsis, with an associated cost of $4.8 billion. (nih.gov)
Etiology1
- Sepsis is fairly unknown to the general public, and complicated by its rapid progression and diverse etiology. (lu.se)
