Management and referral patterns for new-onset chronic cough in primary care patients.

Background: The diagnosis and management of chronic cough in primary care is challenging despite it being one of the most common chronic conditions. Objective: Clinical characterization of patients with new-onset chronic cough in the primary care setting. Methods: This was a retrospective study of adult patients (ages ≥ 18 years) with at least three visits with primary care providers (PCP) for new-onset cough, with at least 8 weeks between the first and third visits, within a tertiary-care center and affiliated clinics between January 1, 2010, and January 1, 2019 (N = 174). We calculated the frequency of primary care visits, diagnostic testing, specialist referrals, and prescribed medications up to 18 months after the third visit with a PCP for cough. Results: Of 174 patients who met the criteria of new-onset chronic cough, >50% had four or more primary care visits related to cough. Despite that, 91 (52.3%) did not receive a referral to a specialist, and 41 (23.5%) did not receive an order for a chest radiograph during the evaluation of the chronic cough. Antibiotics and systemic corticosteroids were prescribed to 106 (61%) and 63 (36%) of the patients, respectively, and 20% were prescribed opiates. No patients were prescribed central-neuromodulating agents, and angiotensin-converting enzyme inhibitors were discontinued in 48% of the patients who were taking them (12/25). Conclusion: We found considerable heterogeneity and discrepancies with clinical guideline recommendations in patients who presented with new chronic cough. There is a substantial unmet need to study chronic cough in the primary care setting to inform important stakeholders.

The Anterior Cruciate Ligament Can Become Hypertrophied in Response to Mechanical Loading: A Magnetic Resonance Imaging Study in Elite Athletes.

BACKGROUND: Evidence, mainly from animal models, suggests that exercise during periods of pubertal growth can produce a hypertrophied anterior cruciate ligament (ACL) and improve its mechanical properties. In humans, the only evidence of ACL hypertrophy comes from a small cross-sectional study of elite weight lifters and control participants; that study had methodological weaknesses and, thus, more evidence is needed. PURPOSE: To investigate bilateral differences in the ACL cross-sectional area (CSA) for evidence of unilateral hypertrophy in athletes who have habitually loaded 1 leg more than the other. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: We recruited 52 figure skaters and springboard divers (46 female and 6 male; mean age, 20.2 ± 2.7 years) because the former always land/jump on the same leg while the latter always drive the same leg into the board during their hurdle approach. Sport training for all participants began before puberty and continued throughout as well as after. Using oblique axial- and oblique sagittal-plane magnetic resonance imaging, we measured the ACL CSA and the anteroposterior diameter of the patellar tendon, respectively. In addition, isometric and isokinetic knee extensor and flexor peak torques were acquired using a dynamometer. Bilateral differences in the ACL CSA, patellar tendon diameter, and knee muscle strength were evaluated via 2-sided paired-samples t tests. Correlations between the bilateral difference in the ACL CSA and age of training onset as well as between the bilateral difference in the ACL CSA and years of training were also examined. RESULTS: A significantly larger ACL CSA (mean difference, 4.9% ± 14.0%; P = .041), as well as patellar tendon diameter (mean difference, 4.7% ± 9.4%; P = .002), was found in the landing/drive leg than in the contralateral leg. The bilateral difference in the ACL CSA, however, was not associated with the age of training onset or years of training. Last, the isometric knee flexor peak torque was significantly greater in the landing/drive leg than the contralateral leg (mean difference, 14.5% ± 33.8%; P = .019). CONCLUSION: Athletes who habitually loaded 1 leg more than the other before, during, and after puberty exhibited significant unilateral ACL hypertrophy. This study suggests that the ACL may be able to be "trained" in athletes. If done correctly, it could help lower the risk for ACL injuries.

Surgery Residents' Experiences With Seriously-Ill and Dying Patients: An Opportunity to Improve Palliative and End-of-Life Care.

OBJECTIVE: To describe how and when surgery residents provided primary palliative care and engaged specialty palliative care services. DESIGN: Phase I consisted of a previously validated survey instrument supplemented with additional questions. We then conducted semistructured interviews with a subset of the survey respondents (Phase II). Using thematic analysis, we characterized surgery residents' perceptions of palliative care delivery among surgical patients. SETTING: General surgery residency programs across the state of Michigan. PARTICIPANTS: General surgery residents across the state of Michigan. All residents in participating programs were invited to complete the survey in Phase I. Phase II consisted of a subset of the survey respondents who underwent semistructured interviews. Interview respondents were sampled to reflect the overall surveyed group. RESULTS: Among 119 survey respondents (response rate 70%), all had encountered a palliative care specialist but only 58.8% had been taught when to consult or to refer to palliative care. Survey respondents reported on a multitude of barriers within the clinician, patient and family, and systemic domains. Interviews expanded on survey findings and 4 influential factors of palliative care delivery emerged: (1) Resident Education and Training; (2) Resident Attitudes Toward Palliative Care; (3) Knowledge of Palliative Care; and (4) Training within a Surgical Culture. CONCLUSIONS: This study reveals how surgery resident training and experiences impact palliative and end-of-life care for surgical patients at teaching institutions. Knowledge of how and when residents are providing primary palliative care and engaging with palliative care services will inform future knowledge and behavioral interventions for trainees who often provide care for patients nearing the end of life.
