Functional outcome and muscle wasting in adults with tetanus.
BACKGROUND: In many countries, in-hospital survival from tetanus is increasing, but long-term outcome is unknown. In high-income settings, critical illness is associated with muscle wasting and poor functional outcome, but there are few data from resource-limited settings. In this study we aimed to assess muscle wasting and long-term functional outcome in adults with tetanus. METHODS: In a prospective observational study involving 80 adults with tetanus, sequential rectus femoris ultrasound measurements were made at admission, 7 days, 14 days and hospital discharge. Functional outcome was assessed at hospital discharge using the Timed Up and Go test, Clinical Frailty Score, Barthel Index and RAND 36-item Short Form Health Survey (SF-36) and 3 and 6 months after discharge using the SF-36 and Barthel Index. RESULTS: Significant muscle wasting occurred between hospital admission and discharge (p70 y of age, functional recovery at 6 months was reduced compared with younger patients. Hospital-acquired infection and age were risk factors for muscle wasting. CONCLUSIONS: Significant muscle wasting during hospitalization occurred in patients with tetanus, the extent of which correlates with functional outcome

Mitigating Unwanted Photophysical Processes for Improved Single-Molecule Fluorescence Imaging
Organic fluorophores common to fluorescence-based investigations suffer from unwanted photophysical properties, including blinking and photobleaching, which limit their overall experimental performance. Methods to control such processes are particularly important for single-molecule fluorescence and fluorescence resonance energy transfer imaging where uninterrupted, stable fluorescence is paramount. Fluorescence and FRET-based assays have been carried out on dye-labeled DNA and RNA-based systems to quantify the effect of including small-molecule solution additives on the fluorescence and FRET behaviors of both cyanine and Alexa fluorophores. A detailed dwell time analysis of the fluorescence and FRET trajectories of more than 200,000 individual molecules showed that two compounds identified previously as triplet state quenchers, cyclooctatetraene, and Trolox, as well as 4-nitrobenzyl alcohol, act to favorably attenuate blinking, photobleaching, and influence the rate of photoresurrection in a concentration-dependent and context-dependent manner. In both biochemical systems examined, a unique cocktail of compounds was shown to be optimal for imaging performance. By simultaneously providing the most rapid and direct access to multiple photophysical kinetic parameters, smFRET imaging provides a powerful avenue for future investigations aimed at discovering new compounds, and effective combinations thereof. These efforts may ultimately facilitate tuning organic dye molecule performance according to each specific experimental demand
