Gram-negative bacteremia occurs more frequently in elderly populations (65 years or older) and is associated with higher morbidity and mortality in this population. [23] E.coli is the most common cause of community-acquired bacteremia accounting for approximately 75% of cases. [24] E.coli bacteremia is usually the result of a urinary tract ...
Diagnosis can be complicated by the fact that many elderly people have preexisting incontinence or dementia. [11] It is reasonable to obtain a urine culture in those with signs of systemic infection that may be unable to report urinary symptoms, such as when advanced dementia is present. [30]
Sepsis will prove fatal in approximately 24.4% of people, and septic shock will prove fatal in 34.7% of people within 30 days (32.2% and 38.5% after 90 days). [105] Lactate is a useful method of determining prognosis, with those who have a level greater than 4 mmol/L having a mortality of 40% and those with a level of less than 2 mmol/L having ...
[8] [10] It is more common in women, in the elderly, in residents of long-term care facilities, and in people with diabetes, bladder catheters, and spinal cord injuries. [11] People with a long-term Foley catheter always show bacteriuria. Chronic asymptomatic bacteriuria occurs in as many as 50% of the population in long-term care.
People with infectious pneumonia often have a productive cough, fever accompanied by shaking chills, shortness of breath, sharp or stabbing chest pain during deep breaths, and an increased rate of breathing. [9] In elderly people, confusion may be the most prominent sign. [9]
The disease primarily affects older adults, persons with weakened immune systems, pregnant women, and newborns. Rarely, people without these risk factors can also be affected. A person with listeriosis usually has fever and muscle aches, often preceded by diarrhea or other gastrointestinal symptoms. Almost everyone who is diagnosed with ...
Adults 65 years of age and older can have a weaker immune response to flu vaccines, making them more likely to get sick with the flu or get flu complications even when vaccinated, according to the ...
Klebsiella ranks second to E. coli for urinary tract infections in older people. [6] It is also an opportunistic pathogen for patients with chronic pulmonary disease, enteric pathogenicity, nasal mucosa atrophy, and rhinoscleroma. [citation needed] New antibiotic-resistant strains of K. pneumoniae are appearing. [7]
