As diluted bdHSSL was compensated for sugars and salts in order to avoid nutrient limitation, changes in μmax were assumed to be caused by the presence of the inhibitory compounds only.
By contrast, in patients with expiratory flow limitation, changes in ventilation, such as an increase in flow and/or in breathing frequency, can elevate FRC above V r.
Although the requirement for a consistent format of the SensorMedic PFT data would appear to be a limitation, changes in the format of the underlying electronic health record data requires substantial revision of many parts of the extract, transform and load process.
There is little evidence that pain and activity limitation change in concert with desirable changes to movement patterns.
Non-compliers showed no difference in their: (i) baseline age, gender, episode duration, general health, depression, low back pain intensity, activity limitation, sick leave, making a LBP-related insurance claim, physically strenuous work, or job satisfaction, nor their (ii) 12 month activity limitation, change in activity limitation from baseline, or sick leave.
In short, I commend the authors in investigating the potential uses of tDCS as a clinical tool but given the above limitations, changes in methodology would need to be implemented before drawing firmer conclusions.
The authors discuss as a limitation that changes in questionnaire ratings may have limited clinical relevance.
Still, freshwater cyanobacterial studies exploring physiological linkages between gene responses to N limitation and changes in cell physiology have been limited, especially for toxic, freshwater genera such as Microcystis.
In Drosophila, nutrient limitation or changes in nutrient-sensing pathways slow germ cell proliferation, reduce germline stem cell number, or both (Armstrong et al., 2014; Drummond-Barbosa and Spradling, 2001; Hsu et al., 2008; LaFever et al., 2010; McLeod et al., 2010; Roth et al., 2012; Sheng and Matunis, 2011).
Latent growth curve models were used to test whether: 1) baseline physical activity was associated with baseline work limitations; 2) changes in physical activity were related to changes in work limitations; and 3) baseline physical activity predicted changes in work limitations.
Therefore, the objective of this study was to prospectively explore the existence of a relationship between patient-physiotherapist agreement on baseline 1) pain intensity and 2) functional limitations, and changes in patient-reported low back pain intensity and related functional limitations, measured four weeks after baseline.
