Outcome in young adults who were diagnosed with complex regional pain syndrome in childhood and adolescence.
2020; 5 (6): e860
Introduction: Complex regional pain syndrome (CRPS) is a neuropathic pain condition of unknown etiology. Little is known of long-term outcomes of young adults who were diagnosed with CRPS as children.Methods: In this study, surveys were mailed to adults who were treated for childhood CRPS at the Lucile Packard Children's Hospital between 1994 and 2018. Completed surveys were analyzed for pain symptoms. Health-related quality-of-life surveys, the Optum SF-8, were analyzed based on norm-based scoring.Results: This study had a 50% response rate. Patients were treated with physical and occupational therapy, peripheral or sympathetic nerve blocks, medication for neuropathic pain, and psychotherapy. Sixty-eight percent of the subjects reported pain. Each 1-year increase in the patient's age at the time of CRPS diagnosis increased the odds of having at least mild pain as an adult by 61% (P = 0.005). Most patients had slightly lower quality-of-life scores than the US population average in both the mental component score (43.4, 95%, confidence interval 3.4) and the physical component score (44.4, 95%, confidence interval 3.3).Conclusions: Young adults in our sample had long-lasting pain symptoms. More than two-thirds of adult patients reported some degree of pain, and these patients had a lower quality of life. Encouraging was that the majority did not have CRPS spreading to other areas, and their pain did not warrant further treatment. Understanding long-term outcomes may lead to risk stratification earlier in the disease to improve future quality of life.

Transition to Practice in Anesthesiology: Survey Results of Practicing Anesthesiologists on Their Experience.
The journal of education in perioperative medicine : JEPM
2019; 21 (2): E619
To assess the experiences and attitudes of practicing anesthesiologists on practice/business management training received during residency and transitioning to practice through an online survey.An online survey, consisting of 39 questions developed by the American Society of Anesthesiologists (ASA) Committee on Young Physicians, was emailed to 2 6551 practicing US anesthesiologists who were ASA members.Questions about individuals' demographic information, transition to practice (TTP) experiences, medical business training, and TTP curricula in residency were included. Results were reported as descriptive statistics.A total of 1199 responses were obtained (response rate 4.5%), and68% reported working in private practice over an average of 17 years. Those practicing ≤ 10 years were more likely to have a TTP curriculum in residency compared to those in practice ≥ 11 years. Common problems reported by many participants regarding TTP included: lack of effective mentorship, inadequate residency curricula/education, and an unfamiliarity with available resources.Although medical business practice education is now required by training programs, there is room for improvement in education. One potential solution is establishing TTP curricula in residency programs, which emphasize the business aspects of medicine and practice management, thus easing trainees from a training to practice environment.

Association of hypoglycemia, hyperglycemia, and glucose variability with morbidity and death in the pediatric intensive care unit
2006; 118 (1): 173-179
We evaluated retrospectively plasma glucose levels and the degree of hypoglycemia, hyperglycemia, and glucose variability in a PICU and then assessed their association with hospital length of stay and mortality rates.Electronic medical records at the Packard Children's Hospital at Stanford University were reviewed retrospectively for all PICU admissions between March 1, 2003, and March 31, 2004. Patients with a known diagnosis of diabetes mellitus were excluded. The prevalence of hyperglycemia was defined with cutoff values of 110, 150, and 200 mg/dL. Hypoglycemia was defined as < or = 65 mg/dL. Glucose variability was assessed with a calculated glucose variability index.In 13 months, 1094 eligible admissions generated 18865 glucose values (median: 107 mg/dL; range: 13-1839 mg/dL). Patients in the highest maximal glucose quintile had a significantly longer median PICU length of stay, compared with those in the lowest quintile (7.5 days vs 1 day). Mortality rates increased as patients' maximal glucose levels increased, reaching 15.2% among patients with the greatest degree of hyperglycemia. Hypoglycemia was also prevalent, with 18.6% of patients (182 of 980 patients) having minimal glucose levels of < or = 65 mg/dL. There was an increased median PICU length of stay (9.5 days vs 1 day) associated with glucose values in the lowest minimal quintile, compared with those in the highest quintile. Hypoglycemia was correlated with mortality rates; 16.5% of patients with glucose levels of < or = 65 mg/dL died. Glucose variability also was associated with increased length of stay and mortality rates. In multivariate logistic regression analyses, glucose variability, taken with hyperglycemia and hypoglycemia, showed the strongest association with mortality rates.Hyperglycemia and hypoglycemia were prevalent in the PICU. Hypoglycemia, hyperglycemia, and, in particular, increased glucose variability were associated with increased morbidity (length of stay) and mortality rates.

Sequence-resolved detecton of pausing by single RNA polymerase molecules
2006; 125 (6): 1083-1094
Transcriptional pausing by RNA polymerase (RNAP) plays an important role in the regulation of gene expression. Defined, sequence-specific pause sites have been identified biochemically. Single-molecule studies have also shown that bacterial RNAP pauses frequently during transcriptional elongation, but the relationship of these "ubiquitous" pauses to the underlying DNA sequence has been uncertain. We employed an ultrastable optical-trapping assay to follow the motion of individual molecules of RNAP transcribing templates engineered with repeated sequences carrying imbedded, sequence-specific pause sites of known regulatory function. Both the known and ubiquitous pauses appeared at reproducible locations, identified with base-pair accuracy. Ubiquitous pauses were associated with DNA sequences that show similarities to regulatory pause sequences. Data obtained for the lifetimes and efficiencies of pauses support a model where the transition to pausing branches off of the normal elongation pathway and is mediated by a common elemental state, which corresponds to the ubiquitous pause.
