The Effects of Secondary Pneumonia on the Curative Efficacy of Multidrug-resistant Tuberculosis: A Retrospective Cohort Study

正Tuberculosis(TB)is a formidable global health problem and ranks above HIV as the leading cause of death world wide.In2017,a total number of 10.0 million cases of TB were reported, which resulted in1.3 million TB deaths. Resistance to standard anti-TB     

Symptom assessment of patients with chronic obstructive pulmonary disease

The primary purpose of this secondary data analysis was to evaluate the efficacy and suitability of the Memorial Symptom Assessment Scale (MSAS) for use with patients with severe chronic obstructive pulmonary disease (COPD). Symptoms experienced by patients with severe COPD were assessed in the original investigation using the 32-item MSAS. The sample consisted of 72 individuals with COPD ranging in age from 36 to 79 years. To increase its efficiency for use with severely ill COPD patients, the original MSAS was shortened to include the 19 most frequently reported symptoms. Reliability of the revised tool remained high (Cronbach's alpha = .86). Content and convergent validity of the revised tool were also established. The revised MSAS appears to be an appropriate measure of the multidimensional, multisymptom experience of patients with severe COPD.     

Symptom clusters related to specific cancers

OBJECTIVES: To examine the current research related to symptom clusters in specific cancer diagnoses. DATA SOURCES: Research studies, review articles. CONCLUSION: Factors that can impact symptoms and their relationship include the stage of disease, treatment used, modification of treatment for the individual patient, patient co-morbidities as well as psychological, sociological, and cultural factors. Understanding is needed regarding which of these factors individually or in combination contribute to symptoms clustering together. The mechanism underlying symptom perception and interpretation need further exploration. Research focus should be on one type of cancer. IMPLICATIONS FOR NURSING PRACTICE: Symptom cluster research offers little at this point to be helpful in patient diagnosis, assessment, monitoring, or management of disease.

Screening tests to detect Chlamydia trachomatis and Neisseria gonorrhoeae infections--2002.

Since publication of CDC's 1993 guidelines (CDC, Recommendations for the prevention and management of Chlamydia trachomatis infections, 1993. MMWR 1993;42[No. RR-12]:1-39), nucleic acid amplification tests (NAATs) have been introduced as critical new tools to diagnose and treat C. trachomatis and Neisseria gonorrhoeae infections. NAATs for C. trachomatis are substantially more sensitive than previous tests. When using a NAAT, any sacrifice in performance when urine is substituted for a traditional swab specimen is limited, thus reducing dependence on invasive procedures and expanding the venues where specimens can be obtained. NAATs can also detect both C. trachomatis and N. gonorrhoeae organisms in the same specimen. However, NAATs are usually more expensive than previous tests, making test performance from an economic perspective a key consideration. This report updates the 1993 guidelines for selecting laboratory tests for C. trachomatis with an emphasis on screening men and women in the United States. (In this report, screening refers to testing persons in the absence of symptoms or signs indicating C. trachomatis or N. gonorrhoeae infection.) In addition, these guidelines consider tests from an economic perspective and expand the previous guidelines to address detection of N. gonorrhoeae as well as C. trachomatis infections. Because of the increased cost of NAATs, certain laboratories are modifying manufacturers' procedures to improve test sensitivity without incurring the full cost associated with screening with a NAAT. Such approaches addressed in these guidelines are pooling of specimens before testing with a NAAT and additional testing of specimens whose non-NAAT test result is within a gray zone. This report also addresses the need for additional testing after a positive screening test to improve the specificity of a final diagnosis. To prepare these guidelines, CDC staff identified pertinent concerns, compiled the related literature published during 1990 or later, prepared tables of evidence, and drafted recommendations. Consultants, selected for their expertise or disciplinary and organizational affiliations, reviewed the draft recommendations. These final guidelines are the recommendations of CDC staff who considered contributions from scientific consultants. These guidelines are intended for laboratorians, clinicians, and managers who must choose among the multiple available tests, establish standard operating procedures for collecting and processing specimens, interpret test results for laboratory reporting, and counsel and treat patients.     

Prevention of oral diseases and oral health promotion.

Research and activities, as promoted in 1989 and 1990, in oral disease prevention and health promotion are summarized. Significant syntheses of research findings have occurred, as a result of planning and workship activities, which will direct oral health promotion in the 1990s. Original research on established and new preventive therapies for dental caries, periodontal diseases, oral mucosal alterations, soft-tissue lesions, precancers and cancers, and trauma are reported, opportunities to prevent oral diseases or maintain oral health through changes in individual behaviors, professional orientation, and social and environmental changes are addressed.
