The strong independent association between self-efficacy and function found in this study suggests that clinical programs in areas such as prevention, geriatric evaluation and management, and rehabilitation should attempt simultaneously to improve physical skills and confidence. Available knowledge of the factors influencing efficacy should guide the development of these efficacy-building programs.

Our findings suggest that predisposition to geriatric syndromes and functional dependence may result when impairments in multiple domains compromise compensatory ability. It may be possible to restore compensatory ability and prevent or delay the onset of several geriatric syndromes and, perhaps, functional dependence by modifying a shared set of predisposing factors. Perhaps it is time to take a more unified approach to the geriatric syndromes and functional dependence.

Several readily identifiable factors appeared to distinguish the subgroup of older fallers at risk for suffering a serious fall injury. These factors should help guide who and what to target in prevention efforts.

The clinical significance of micrometastasis of colorectal cancer (CRC) to regional lymph nodes remains controversial. In this review, we analyze publications that have evaluated the clinical significance of occult lymph node metastasis in CRC. An extensive literature search identified 19 publications that evaluated the clinical significance of micrometastatic CRC by various methods, including immunohistochemistry (IHC; n ‫؍‬ 13) and reverse transcription-polymerase chain reaction (RT-PCR, n ‫؍‬ 6). These studies were reviewed for methodology and findings. Significant limitations in methodology were identified, including inconsistent histological definitions of micrometastatic disease, poor sampling because of an inadequate number of lymph nodes or number of sections per lymph node analyzed, lack of conformity with respect to IHC antibody or RT-PCR marker, and inadequate power because of small sample size. Micrometastatic lymph node metastasis identified by RT-PCR was consistently found to be prognostically significant, but this was not true of micrometastatic disease identified by IHC. RT-PCR analysis of lymph nodes with specific markers can help identify pN0 (pathological-negative lymph node) CRC patients at increased risk for recurrence. The identification of occult disease by IHC techniques may also ultimately prove to be associated with worse outcome, but a number of inadequately powered studies have concluded conversely.
