ABSTRACT
Background: An intricate physiological and pathophysiological connection exists between the heart and lungs, which is especially important in individuals with spinal cord injury (SCI). While an exercise intervention may seem the best approach to leverage this relationship, the prior work has shown that, despite numerous health benefits, regular exercise training does not improve cardiorespiratory control in individuals with SCI. Breath training presents an alternative intervention that is uniquely accessible, with yogic breathing directly engaging linked fluctuations in respiration and cardiovascular control. In addition, there is evidence across a range of populations that regular yogic breathing reduces cardiovascular disease risk. It is possible that the chronic decrease in breathing frequency associated with regular yogic breathing, rather than the specific yogic breathing techniques themselves, is the primary contributor to the observed risk reduction. Methods: Therefore, in 12 individuals with traumatic SCI from C4 to T8, the authors compared Unpaced and conventional 0.083 Hz (Slow) paced breathing with various yogic breathing techniques including: (1) inspiratory-expiratory breath holds (i.e., Kumbhaka or "Box Breathing"), (2) extended exhalation (1:2 duty cycle), and (3) expiratory resistance via throat constriction (i.e., Ujjayi). Beat-to-beat heart rate and blood pressure were measured as well as end-tidal CO2 and O2 saturation were measured. Statistical analysis was performed using a one-way repeated-measures analysis of variance with post hoc pairwise t tests corrected for multiple comparisons. Results: As expected, all slow breathing patterns markedly increased respiratory sinus arrhythmia (RSA) compared with Unpaced in all (n = 12) individuals. More importantly, Ujjayi breathing appeared to improve ventilatory efficiency over Unpaced breathing in individuals with SCI by increasing O2 saturation (97.6% vs. 96.1%; p = 0.042) and tended to decrease end-tidal CO2 (32 mmHg vs. 35 mmHg; p = 0.08). While other slow breathing patterns demonstrated similar effects, only Ujjayi improved RSA while increasing heart rate and improving ventilatory efficiency. Conclusions: Hence, slow breathing per se can result in important cardiorespiratory changes, but the yogic breathing practice of Ujjayi, with glottic throat resistance, may hold the greatest promise for improving cardiorespiratory control in individuals with SCI (CTR ID No. NCT05480618).
ABSTRACT
Patient: Female, 58-year-old. Final Diagnosis: Benign recurrent lipoma following incomplete surgical removal. Symptoms: Discomfort, Aesthetic Dissatisfaction. Clinical Procedure: Surgical Revision-Excision-Exploration with Lipoma Extraction. Specialty: Plastic Surgery (Hand Surgery). Objective: Unusual Clinical Presentation and Course. Background: Lipoma is a usually painless tumor composed of adipocytes, of fat cells, arising from mesenchymal tissue. It manifests itself in locations in the body where adipocytes are and has circumscribed growth. Its incidence in the hand is relatively low (1%-4.9%). Despite most lipomas being benign and usually asymptomatic, the location of lipoma can lead to nerve compression symptoms. We report a case of an unusual recurrence of lipoma in the wrist after incomplete excision. Case report: A 58-year-old female presented with a large, soft mass located on the volar side of the wrist, which recurred during the first week following the initial excision. While the patient did not exhibit symptoms of nerve compression, she reported experiencing swelling and pain at the surgical site postoperatively. The patient underwent surgical re-excision of the lesion, and the excised tissue was sent for histological examination. The subsequent histological analysis confirmed the diagnosis of a benign lipoma. The patient expressed satisfaction with the surgical revision, postoperative care, and outcomes, reporting high levels of contentment in pain relief, functional improvement, and cosmetic results. Conclusions: Lipomas often remain asymptomatic for extended periods, only becoming a source of discomfort or concern once they increase in size or impact one's appearance. Although most lipomas are benign and pose little risk to overall health, certain malignant variants exist. Recurrence of lipoma is uncommon and typically suggests an incomplete initial excision. In anatomically complex regions like the hand or wrist, meticulous planning and preoperative imaging are essential to prevent compression, exclude malignancy, and preserve function.
