“…After all, the popular press constantly barrages us with similar entertaining lists of facts we didn't know about certain things. Squissato and Brown 1 have selected some interesting articles on which to comment from many thousands of possible articles. The danger of this approach was that it was completely at the discretion of the authors to select what they considered important topics and to hopefully then give an unbiased assessment of that topic.…”

“…[1][2][3][4][5] Lowquality studies do not adequately assess sodium intake, they use extreme variation in dietary sodium and they measure outcomes over a duration of a few days. They do not address known confounding factors for the outcomes being tested nor do they control for blood pressure (the main mechanism of sodium-induced harm) and they are conducted in populations with diseases where reverse causality is likely.…”

“…The publication of such studies, leveraged by the private sector, has created a false aura of scientific controversy around dietary salt. [1][2][3][4][5] Although the call for a large randomized controlled trial on dietary sodium is not new, it has limited feasibility in Western countries where the food supply contains so much sodium. 6 In Africa, where some populations still have low sodium intake, it was deemed unethical to increase dietary sodium in a trial setting.…”

“…CTS ranks amongst the top leading causes of days lost from work and productivity loss, affecting 0.7 per 10,000 workers annually [ 4 ]. In the occupations that impose a high physical burden on the upper extremity, such as ‘administrative and secretarial’ and ‘skill trades’ the annual incidence of CTS is as high as 82 and 136 per 10,000 workers, respectively [ 5 ]. Signs and symptoms of CTS are predominantly represented by pain, numbness, tingling, and weakness of the wrist and hand area innervated by the median nerve (lateral 3.5 digits) [ 2 , 6 ].…”

Background Accurate diagnosis of carpal tunnel syndrome (CTS) is essential for directing appropriate treatment; and for making decisions about work injury claims. The Kamath and Stothard Questionnaire (KSQ) is a self-reported tool used for the diagnosis of CTS. Comprehensibility and comprehensiveness of this questionnaire are critical to diagnostic performance and need to be established. The purpose of the study was to describe how potential respondents, clinicians, and measurement researchers interpret KSQ questions in order to identify and resolve potential sources of misclassification. Methods Hand therapists, measurement researchers, participants with CTS, and a control group were interviewed using cognitive interviewing techniques (talk aloud, semi-structured interview probes) in Hamilton, Canada. All interviews were recorded and transcribed verbatim. A directed content analysis was done to analyze the interviews using a previously established framework. Findings Eighteen participants were interviewed. Areas, where questions were unclear to some participants, were recorded and categorized into five themes: Clarity and Comprehension (52%), Relativeness (38%), Inadequate Response Definition (4%), Perspective Modifiers (4%), and Reference Point (2%). Respondents also identified several symptoms of CTS that are not covered by the KSQ that might be of diagnostic value, e.g., weakness and dropping items. Conclusion The content validity of the current iteration of the KSQ was not established. The problematic questions identified in the study have been reported to have low specificity and negative predictive values in a previous quantitative study. The content validity issues identified may explain the poor performance. Recommendations were made to modify the wording of the KSQ and the potential addition of three new questions. Future studies should determine whether the modified questionnaire can provide better diagnostic accuracy and psychometric properties. The results of this study may assist in ruling in or out CTS diagnosis to a wide variety of target audience, such as hand specialists, physical and occupational therapists, as well as family doctors.

“…Carpal tunnel syndrome (CTS) is a common cause of upper extremity disability, with an average incidence of 103 per 100,000 people per year in Canada and even higher incidences in some occupations. 1 , 2 Carpal tunnel release (CTR) has become the most commonly performed surgical procedure in the hand. 3 Outcomes following CTR surgery are generally favorable, with 70%–90% of patients having good to excellent outcomes; however, some patients have poor outcomes and higher postsurgical pain despite a perceived technical success by the surgeon.…”

Purpose: Outcomes following carpal tunnel release (CTR) are generally favorable. When patient satisfaction or symptom resolution is not as expected, understanding what factors contribute to that outcome could allow for strategies targeted at improving results. Our purpose was to determine if measurable mental health factors, specifically resilience and pain catastrophization, correlate with patients' postoperative outcomes following CTR. Methods: A prospective cohort study was performed. Ninety-four patients were recruited to take part in the study. Patients completed written consent, the Boston Carpal Tunnel Questionnaire (BCTQ), the Pain Catastrophizing Scale, and the Brief Resilience Scale. A single surgeon, or his resident under supervision, performed an open CTR under local anesthetic. Our primary outcome measure was a repeat BCTQ at 6 months. Pearson correlation coefficients and univariate analyses were performed to assess the correlation between Pain Catastrophizing Scale and Brief Resilience Scale scores and final BCTQ scores. Results: Forty-three and 63 participants completed the BCTQ at 3 and 6 months, respectively. This was 10% below the number needed to achieve appropriate power. Among those that responded, all participants showed improvement in their symptoms (P ¼ .001). There was no correlation between patients' Pain Catastrophizing Scale or Brief Resilience Scale scores and 6-month BCTQ scores or the amount of improvement in the BCTQ at final follow-up. Conclusions: Most participants improved following CTR. Patients' self-assessed resilience, and the degree of pain catastrophization did no correlate with the amount of improvement patients had after surgery. Type of study/level of evidence: Prognostic II.
