The National Library of Medicine (NLM) is the coordinator of a national network of medical libraries with over 6,000 members. The reliability of the information provided by the centers, divisions and other units of NLM is backed by professional opinions of independent experts in their respective fields. Founded in 1836, NLM provides access to up-to-date information and electronic resources. Millions of people can take advantage of the data made available by The National Library of Medicine, and there is also an impressive print collection to explore. The website of the Library of Medicine offers free articles on a range of subjects, a medical dictionary, information on drugs and diseases, as well as results of clinical trials and important biomedical literature for self-education.

One of NLM’s purposes is to make as much medical information as possible available to millions of individuals and thousands of communities in the United States of America and other parts of the world. The National Library of Medicine works closely with international organizations, federal agencies and public health institutions for the scientific information to be widely available at any time. From the moment of its foundation, the National Library of Medicine has been representing medical societies, foundations, health science libraries and hospitals trying to inform the public and make everyone aware of the recent developments in the field.

The National Library of Medicine offers plenty of exciting opportunities when it comes to learning more about the history of medicine. Everyone interested can visit local exhibits that historians from NLM organize, hosted by local universities and libraries. NLM tours are available to those visiting Washington DC, along with exhibitions, workshops and interactive computer displays.  Using NLM, one can easily access around 18 million references from several thousand biometric journals. Often, there is a link to the full text of the article you are interested in, which helps the library promote health awareness and inform the public of new developments in the industry. The importance of National Library of Medicine is difficult to overestimate, as it’s currently one of the most well-known centers offering education opportunities and making significant contribution to health sciences in the United States.

Ring-Calcification of Coronary Artery Aneurysms in an Adolescent

Figure 1. Right anterior oblique view (left) and posteroanterior view (right), showing an oval calcification at the base of the heart (arrow). _ _

Kawasaki disease is an acute febrile illness of unknown etiology, which occurs predominantly in infancy and early childhood. Coronary artery aneurysms develop in approximately 15 to 20 percent of children during the acute stage of the disease. Although follow-up coronary angiography one to two years later has revealed regression of the coronary aneurysms in more […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Conclusion

Contrary to the poor predictive value, on an individual basis, of the aforementioned indices to assess the outcome of COPD, a very important prognostic factor in this group of older people appeared to be the presence of coincident or subsequent associated severe diseases, such as arteriosclerotic heart disease, pulmonary embolism, and serious gastrointestinal bleeding. Almost […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Outcome

When one specifically considers studies that followed patients with COPD after a severe acute episode of respiratory insufficiency, it appears that an immediate recovery after the acute decompensation is likely: respectively, 63, 70, 74, 75, and 94 percent of the patients survived the acute episode in publications by Asmundsson and Kilburn, by Gottlieb and Balchum, […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Discussion

Our carefully defined population sample consists of patients suffering from severe COPD and acute superimposed respiratory failure who required mechanical ventilation. Asthma or other chronic respiratory diseases were excluded, and we believe that we have observed longitudinally a homogeneous group of patients. In addition, the same type of treatment, mechanical ventilation, and respirator weaning procedure […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Multivariable analysis

Figure 2. Duration of mechanical ventilation (MV) and age of patients with COPD. Only patients who survived their extubation longer than ten days are considered (subsets A2 and B; see text).

To find variables defining “very early” deaths (occurring during mechanical ventilation or less than ten days after extubation; subset Al) and “early” deaths (subset A2, ie, all other patients in group A), we compared these two subsets in Table 4. Patients who did not survive mechanical ventilation longer than ten days proved not to have […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Results

Figure 1. Survival plot of 39 patient-episodes of COPD which required mechanical ventilation for acute respiratory failure.

Between July 1,1982 and March 1,1985, there were 35 patients with COPD who had to be intubated for decompensation of their condition and who were eligible for this study. Their anthropometric and pulmonary functional data are listed in Table 1. These patients accounted for 39 periods of mechanical ventilation during the study; two patients (patients […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Nutritional Parameters

Nutritional Parameters Serum levels of protein, albumin, phosphate, potassium, and creatinine were recorded from the charts, as were body weight and height at admission, in order to evaluate the nutritional status. In cases with more than one determination of these parameters, the value closest to the intubation date was considered. The percentage of normal weight […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Measurements during Acute Respiratory Failure

Measurements during Acute Respiratory Failure From each chart the hematocrit reading on admission to the hospital, arterial blood gas levels immediately preceding intubation, and nutritional parameters (discussed subsequently) were recorded. During mechanical ventilation, evidence of infection (chest roentgenogram showing a new pulmonary infiltrate, elevated white blood cell count, fever, increased production of sputum, cultures of […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation: Materials and Methods

Patients All consecutive patients suffering from COPD who were mechanically ventilated for their respiratory condition in our ICU between July 1,1982 and March 1,1985 were studied; COPD was defined as an obstructive respiratory syndrome assessed by pulmonary function tests showing a ratio of the forced expiratory volume in one second over the forced vital capacity […]

Failure to Predict Six-Month Survival of Patients with COPD Requiring Mechanical Ventilation

A Prospective Study The natural course of chronic obstructive pulmonary -disease (COPD) is characterized by recurrent exacerbations of respiratory failure, and mechanical ventilation appears often to be the only therapeutic tool available to avoid an imminent fatal outcome. Mechanical ventilation seems ideally suited to such a situation: it provides both oxygen and mechanical power to […]
