Studies comparing endocrine-specific outcomes following parathyroidectomy (PTx) versus concurrent parathyroidectomy and thyroidectomy (PTx+Tx) are few.
10,019 patients were selected from the Collaborative Endocrine Surgery Quality Improvement Program (2014-2019). Baseline characteristics and short-term (≤30 days) outcomes for PTx+Tx vs PTx patients were compared using bivariate and multivariable methods.
PTx+Tx patients were more likely to experience clinical hypoparathyroidism (6.7% vs 0.5%, p<0.001), recurrent laryngeal nerve transection, (0.4% vs 0.1%, p=0.002) and hematoma requiring evacuation (1.0% vs 0.2%, p<0.001). Readmissions and ED visits for hypocalcemia were more frequent after PTx+Tx vs PTx. Concurrent surgery was associated with an 8-fold increase in risk of short-term complications (Odds Ratio (OR) 8.0, 95% Confidence Interval (CI) 5.7-11.1, p<0.001).
Patients undergoing PTx+Tx have increased rates of postoperative complications, ED visits, and readmissions compared to patients undergoing parathyroidectomy alone. These findings could help guide surgeon-patient discussions on the risks of concurrent surgery.

Wearable monitors can allow continuous vital signs monitoring, send data wirelessly to the electronic healthcare record, and reduce the number of unplanned admissions to intensive care.The association of left ventricular ejection fraction (LVEF) with procedural and long-term outcomes after state-of-the-art percutaneous coronary intervention (PCI) of bifurcation lesions remains unsettled. A total of 5,333 patients who underwent contemporary coronary bifurcation PCI were included in the intercontinental retrospective combined insights from the unified RAIN (veRy thin stents for patients with left mAIn or bifurcatioN in real life) and COBIS (COronary BIfurcation Stenting) III bifurcation registries. Of 5,003 patients (93.8%) with known baseline LVEF, 244 (4.9%) had LVEF less then 40% (bifurcation with reduced ejection fraction [BIFrEF] group), 430 (8.6%) had LVEF 40% to 49% (bifurcation with mildly reduced ejection fraction [BIFmEF] group) and 4,329 (86.5%) had ejection fraction (EF) ≥50% (bifurcation with preserved ejection fraction [BIFpEF] group). The primary end point was the Kaplan-Meier estimate of major adverse cardiac events (MACEs) (a composite of all-cause death, myocardial infarcti although a strong predictor of long-term MACEs, does not affect procedural outcomes.Data on depression and stress among patients with spontaneous coronary artery dissection (SCAD) are limited. selleck Using data from the VIRGO (Variation in Recovery Role of Gender on Outcomes of Young AMI Patients) study, which prospectively enrolled 3,572 acute myocardial infarction (AMI) patients between 18 and 55 years of age, we identified 67 SCAD cases. We compared Patient Health Questionnaire-9 (PHQ-9) and 14-item Perceived Stress Scale (PSS-14) scores obtained at baseline, 1 month, and 12 months between SCAD and AMI of all other causes. Using longitudinal linear mixed-effects analysis, we compared depression and stress scores between SCAD and other AMI, adjusting for time and selected covariates. Patients with SCAD had lower baseline PHQ-9 scores (6.1 ± 6.0 vs 7.7 ± 6.4 for other patients with AMI, p = 0.03), similar 1-month scores, and lower 12-month scores (3.2 ± 4.3 vs 4.9 ± 5.5, p = 0.004). At baseline and 1 month, patients with SCAD had similar PSS-14 scores to those of other patients with AMI. At 12 months, patients with SCAD had lower scores (18.4 ± 8.8 vs 21.5 ± 9.3 for other patients with AMI, p = 0.009). After adjustment for cardiovascular risk factors, co-morbidities, and clinical acuity, no differences in PHQ-9 or PSS-14 scores remained between SCAD and other AMI. Similar results were obtained in a subgroup analysis of only women with SCAD and other AMI. In conclusion, patients with SCAD had a relatively lower burden of depression and perceived stress than other patients with AMI, potentially because of fewer co-morbidities and favorable socioeconomic factors. However, given high depression and stress burden in both SCAD and other patients with AMI, routine screening can help identify and treat these patients.Electrical storm (ES) is a life-threatening condition that may lead to recurrent arrhythmias, need for ventricular mechanical support, and death. The study aimed to assess the burden of arrhythmia recurrence and in-hospital outcomes of patients admitted for ES in a large urban hospital. We performed a retrospective analysis of patients admitted with ventricular arrhythmias from January 2018 to June 2021 and identified 61 patients with ES, defined as 3 or more episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) within 24 hours. We reviewed the in-hospital outcomes and compared outcomes between patients who had no recurrence of VT/VF after the first 24 hours (34 [56%]), those with recurrence of 1 or 2 episodes of VT/VF within a 24-hour period (15 [24%]), and patients with 3 or more recurrent VT/VF events consistent with recurrent ES after the first 24 hours (12 [20%]). Patients with recurrent ES had significantly higher in-hospital mortality as compared with those with recurrent VT/VF not meeting criteria for ES or no recurrences of VT/VF (3 [25%] vs 0 [0%] vs 0 [0%]; p = 0.002). Moreover, patients with recurrent ES also had higher rates of the combined end points of ventricular mechanical support and death (7 [58%] vs 1 [6%] vs 1 [3%], p less then 0.001), invasive mechanical ventilation and death (10 [83%] vs 2 [13%] vs 2 [6%], p less then 0.001), catheter ablation or death (12 [100%] vs 7 [47%] vs 12 [35%], p less then 0.001) and heart transplantation and death (3 [25%] vs 2 [13%] vs 0 [0%], p = 0.018). In conclusion, patients admitted with ES have a high risk of in-hospital recurrence, associated with extremely poor outcomes.Heart failure (HF) affects 6 million people in the United States and costs $30 billion annually. It is unclear whether improvements in length of stay and mortality over the last few decades hold true for both systolic and diastolic HF. To better assess the epidemiological and economic burden of HF, we assessed the trends in outcomes and costs for both systolic and diastolic HF. We identified hospitalizations for systolic and diastolic HF in the National Inpatient Sample database and evaluated trends over the period from 2004 to 2017, adjusting for demographics and co-morbidities. The proportion of patients admitted with an exacerbation of systolic HF increased from 42% to 63% over the study period. We found an overall decreasing trend between 2004 and 2011 in the length of stay for HF in general with a sharper decrease in diastolic than systolic HF. Inpatient mortality decreased between 2004 and 2007 and stabilized between 2008 and 2016. Systolic HF was associated with higher mortality than diastolic HF. The total inflation-adjusted cost did not change significantly over the study period, with systolic HF costing, on average, $3,036 more than diastolic HF per admission. In conclusion, systolic HF overtook diastolic HF, accounting for most HF hospitalizations in 2008. The higher hospitalization costs for systolic HF relative to diastolic HF may have resulted, in part, from greater use of advanced support devices in patients with systolic HF.
Initial orthostatic hypotension (IOH) is a form of orthostatic intolerance defined by a transient decrease in blood pressure upon standing. Current clinical recommendations for managing IOH includes standing up slowly or lower body muscle tensing (TENSE) after standing. Considering that IOH is likely due to a large muscle activation response resulting in excessive vasodilation with a refractory period (<2 minutes), we hypothesized that preactivating lower body muscles (PREACT) before standing would reduce the drop in mean arterial pressure (MAP) upon standing and improve presyncope symptoms.
The purpose of this study was to provide IOH patients with effective symptom management techniques.
Study participants completed 3 sit-to-stand maneuvers, including a stand with no intervention (Control), PREACT, and TENSE. Continuous heart rate and beat-to-beat blood pressure were measured. Stroke volume and cardiac output were then estimated from these waveforms.
A total of 24 female IOH participants (mean ± SD 32 ± 8 years) completed the study. The drops in MAP following PREACT (-21 ± 8 mm Hg; P <.001) and TENSE (-18 ± 10 mm Hg; P <.001) were significantly reduced compared to Control (-28 ± 10 mm Hg). The increase in cardiac output was significantly larger following PREACT (2.6 ± 1 L/min; P <.001) but not TENSE (1.9± 1 L/min; P = .2) compared to Control (1.4 ± 1 L/min). The Vanderbilt Orthostatic Symptom Score following PREACT (9±8 au; P = .033) and TENSE (8 ± 8 au; P = .046) both were significantly reduced compared to Control (14 ± 9 au).
Both the drop in MAP and symptoms upon standing improved with either PREACT or TENSE. These maneuvers provide novel symptom management techniques for patients with IOH.

An ICA abutting the upper rib and running in the subcostal groove was defined as the lowest risk zone for interventions requiring a supracostal needle puncture. A theoretical high-risk zone was defined by the ICA coursing in the lower half of the intercostal space (ICS), and a theoretical moderate-risk zone was defined by the ICA coursing below the subcostal groove but in the upper half of the ICS. Arterial phase computed tomography data from 250 patients were analyzed, revealing demographic variability, with high-risk zones extending more laterally with advancing age and with more cranial ribs. Overall, within the 97.5th percentile, an ICS puncture >7-cm lateral to the spinous process incurs moderate risk and >10-cm lateral incurs the lowest risk.Percutaneous glue embolization was investigated as a treatment for bronchopleural fistulae (BPFs) and alveolar-pleural fistulae (APFs) associated with persistent air leak. Seven consecutive patients with persistent air leak were treated with percutaneous glue embolization of the BPF/APF from both iatrogenic and spontaneous causes. Treatment was performed using direct n-butyl cyanoacrylate (nBCA) glue injection for discrete, visible fistulae (n = 4), fibrin glue spray for suspected tiny multifocal leaks (n = 2), or both (n = 1). The number of treatments required per patient was 1 (n = 3), 2 (n = 3), or 3 (n = 1). Technical success was achieved in all cases. Follow-up showed resolution of all air leaks, with mean chest tube removal at 7.1 days after the embolization. The follow-up duration ranged from 2 to 47 months. No significant procedure-related morbidity, mortality, or recurrence was encountered. Percutaneous treatment for persistent BPFs and APFs showed good efficacy in this small case series and warrants further investigation.
