Significant Difference In Mortality Research Articles

Relationship between waist-to-height ratio and heart failure outcome: A single-centre prospective cohort study.

This study sought to evaluate the correlation between waist-to-height ratio (WHtR) and heart failure (HF) outcomes across different ejection fraction (EF) categories. A prospective cohort study was conducted at a comprehensive tertiary hospital in China. The participants were categorized by WHtR and EF quartiles. Outpatient or telephone follow-up occurred every 6months after the diagnosis of heart failure. The primary endpoint was all-cause mortality at 48months. Cox proportional hazard regression analyses were employed to evaluate the association between WHtR and all-cause mortality. Among 859 enrolled participants, 545 (63.4%) were male, and the mean age was 65.2±11.1years. After adjusting for age and sex, WHtR demonstrated a strong correlation with both BMI (correlation=0.703, P=0.000) and WHR (correlation=0.609, P=0.000). Individuals with a high WHtR (≥0.50) had a higher prevalence of hypertension (56.4% vs. 39.6%) and diabetes (26.5% vs. 13.7%), higher levels of TC (3.61±1.55 vs. 3.36±0.90mmol/L), TG (1.40±0.81 vs. 1.06±0.59mmol/L), and LDL-C (2.03±0.85 vs. 1.86±0.76mmol/L) compared with patients with low WHtR (<0.50). NT-proBNP levels were inversely correlated with EF values in both low and high WHtR groups. A total of 149 (18.9%) patients died at the conclusion of the follow-up period. The incidence of all-cause and cardiovascular death was higher in the low WHtR group compared with the high WHtR group [HRs=1.83 (1.30-2.58), 1.96 (1.34-2.88), respectively]. There was no significant difference in noncardiovascular mortality or rehospitalization rates between the two groups. Patients with HFrEF/low WHtR exhibited a markedly elevated risk of all-cause mortality [HR=2.31; (95% CI: 1.24-4.30)], heart failure mortality [HR=3.52; (95% CI: 2.92-8.80)], and noncardiovascular mortality [HR=4.59; (95% CI: 1.19-17.76)] compared with patients with HFrEF/high WHtR. WHtR has a negligible effect on the risk of all-cause and cardiovascular mortality in heart failure patients with preserved EFs. The obesity paradox, as delineated by WHtR, is observed in patients with HFrEF, yet absent in those with HFpEF.

Comparison of High-Dose versus Low-Dose Trimethoprim–Sulfamethoxazole for Treating Pneumocystis jirovecii Pneumonia among Hemodialysis Patients: A Nationwide Database Study in Japan

Background: Hemodialysis patients are at high risk for developing Pneumocystis jirovecii pneumonia (PJP), and trimethoprim–sulfamethoxazole (TMP–SMX) is the first-line agent for treating this disease. However, there is a lack of consensus on the required dosage of TMP–SMX for hemodialysis patients. Methods: This study used the nationwide Japanese Diagnosis Procedure Combination database to review hemodialysis patients hospitalized for PJP from April 2014 to March 2022. Eligible patients were divided into high-dose and low-dose groups based on the median daily dose per body weight of TMP. The 90-day mortality and adverse events after propensity score matching were compared between the groups. Results: A total of 126 hemodialysis patients with PJP were included, and the median daily dose per body weight of TMP was 5.74 mg/kg/day (interquartile range: 4.33–8.18 mg/kg/day). Thirty-two pairs were analyzed after the propensity score matching. No significant differences in the 90-day mortality and proportion of adverse events were observed between the high-dose and low-dose groups. Conclusions: A high dose of TMP–SMX is unlikely to decrease the in-hospital mortality and adverse events among hemodialysis patients with PJP. However, the results should be interpreted with caution, given the lack of power and lack of long-term follow-up. Additional prospective interventional studies are required to validate these results.

Inflammatory bowel disease and pulmonary embolism: a nationwide perspective.

To examine the characteristics and outcomes of patients with inflammatory bowel disease (IBD) hospitalized with pulmonary embolism (PE). This cross-sectional observational study analyzed data from the 2016 to 2019 National Inpatient Sample to investigate hospitalizations for PE in the USA, stratified by the presence or absence of IBD. Adult patients were selected using the International Classification of Diseases, Tenth Revision codes for PE, Crohn's disease, and ulcerative colitis. Data on patient demographics, comorbidities, and hospital characteristics were collected. Statistical analysis included univariable and multivariable logistic regression using Stata/BE 17.0, focusing on in-hospital mortality and complications in PE patients with and without IBD. Adjusted odds ratios (aOR) and their corresponding 95% confidence intervals (CI) were calculated when appropriate. PE/IBD group was younger (mean age 58.3 vs. 62.7 years; P < 0.001), had a higher proportion of white patients (81.2% vs. 70.9%; P < 0.001), and had a greater prevalence of chronic liver disease (7.54% vs. 6.02%; P = 0.002) when compared to PE/non-IBD patients. The PE/IBD group had lower prevalence rates of coronary artery disease, congestive heart failure, obesity, chronic obstructive pulmonary disease, hypertension, and diabetes. Regarding primary outcomes, there was no significant difference in in-hospital mortality between the two groups (aOR, 0.92; 95% CI, 0.77-1.09; P = 0.355). However, the IBD/PE group had a higher risk of acute kidney injury, sepsis, septic shock, cardiac arrhythmias, and deep vein thrombosis. As for secondary outcomes, PE/IBD patients had more extended hospital stays and higher healthcare costs compared with PE/non-IBD patients. Hospitalized PE patients with IBD differ demographically and have a different comorbidity profile compared to those without IBD. PE/IBD patients demonstrate greater use of healthcare resources and elevated risk of hospitalization adverse events than PE/non-IBD patients, highlighting the necessity for individualized management approaches in this population.

Robot-Assisted Minimally Invasive Coronary Artery Bypass Grafting: Total Arterial Revascularization Using the Double-Docking Technique.

The right internal mammary artery is considered to be the second choice for arterial conduits for coronary artery bypass grafting (CABG). However, the widespread use of bilateral internal mammary artery (BIMA) grafting is limited owing to increased technical demands, lengthy procedure, and high incidence of sternal wound complications. We compared the early clinical outcomes of a novel robot-assisted double-docking technique (DDT) with an open sternotomy technique for total arterial revascularization using BIMA. Between June 2019 and June 2023, 445 patients with multivessel coronary artery disease underwent open sternotomy CABG using BIMA grafting and 145 patients underwent robot-assisted BIMA grafting using DDT. Comparative analysis of 104 pairs of matched patients obtained using propensity score matching was performed. Procedural characteristics, postoperative 30-day mortality, and composite outcome (major adverse cardiac and cerebrovascular events) at a median follow-up of 1.5 years were evaluated. Preprocedural characteristics were well balanced between the groups after propensity matching. The number of distal anastomoses performed in the conventional group was statistically higher than that performed using DDT (P < 0.001). The durations of postsurgical ventilation, intensive care unit stay, and in-hospital stay were significantly lower with the DDT than with conventional CABG (P < 0.001). There was no significant difference in all-cause mortality or major adverse cardiac events between the DDT and conventional CABG groups at a median follow-up of 1.5 years. The DDT is feasible and efficacious for revascularization of multiple coronary targets in select individuals. It is equivalent to open sternotomy in terms of early clinical outcomes and superior to open sternotomy with regard to rates of sternal infection and intensive care unit and in-hospital stay.

Characteristics and outcomes of home parenteral nutrition among children with severe neurological impairment.

To describe the characteristics, secular trends, and outcomes of home parenteral nutrition (HPN) use among children with severe neurological impairment (SNI) and non-primary digestive disorders from 2010 to 2023 and compare outcomes to children with primary digestive disorders on HPN. A retrospective review of all children with SNI and non-primary digestive disorders, where HPN was initiated between January 2010 and September 2023 at a tertiary care pediatric hospital. The Mann-Kendall trend test was used to assess trends in HPN initiation. We compared acute care service utilization in the year prior and following HPN initiation. Mortality and ability to achieve enteral autonomy outcomes were compared to those of children with HPN and primary digestive disorders. Of the 205 included children with HPN, 18 children had SNI and non-primary digestive disorders, 187 children had primary digestive disorders. There was an increase in HPN initiation among children with SNI and non-primary digestive disorders (p = 0.002) between 2010 and 2020. Among children with SNI and non-primary digestive disorders, HPN-related complications (line-associated infection/thrombus, nephrolithiasis, cholelithiasis) occurred in 72%. There was no change in acute care utilization in the year prior versus year following HPN initiation. Compared with the primary digestive disorders group, children with SNI and non-primary digestive disorders were less likely to achieve enteral autonomy (p < 0.0001); however, no significant differences in mortality were observed (22% vs. 8%, p = 0.09). HPN is increasingly being used among SNI children with non-primary digestive disorders. Compared to children with primary digestive disorders on HPN, those with SNI are less likely to achieve enteral autonomy.

Ventilatory pressure parameters impact the association between acute gastrointestinal injury and all-cause mortality in mechanically ventilated patients

Acute gastrointestinal injury (AGI) is common in mechanically ventilated (MV) patients, but the potential association between ventilatory pressure parameters and AGI grade and their impact on mortality remains unclear. This study aimed to explore the association between ventilatory pressure parameters and AGI grade, and their interaction on all-cause mortality in MV patients. This study was a secondary analysis of a multicenter, prospective, observational study that enrolled adult patients with an expected duration of mechanical ventilation ≥ 48 h from 14 general intensive care units in Zhejiang Province between March and August 2014. The AGI grade was assessed daily on the basis of gastrointestinal symptoms, intra-abdominal pressures, and feeding intolerance in the first week of admission to the ICU. This study included 331 patients (69.2% men; mean age, 64.6 ± 18.9 years). Multivariate regression analysis showed that plateau pressure (Pplat) (OR 1.044, 95% CI 1.009–1.081, P = 0.013), serum creatinine (OR 1.003, 95% CI 1.001–1.006, P = 0.042) and APACHE II score (OR 1.035, 95% CI 1.021–1.072, P = 0.045) were independently associated with global AGI grade III/IV within 7 days of ICU admission. Moreover, global AGI grade (HR 2.228, 95% CI 1.561–3.182, P < 0.001), serum creatinine (HR 1.002, 95% CI 1.001–1.003, P = 0.012) and APACHE II score (HR 1.039, 95% CI 1.015–1.063, P = 0.001) were independently associated with 60-day mortality. In addition, there were significant (Pint ≤ 0.028) interactions of Pplat and DP with AGI grade in relation to 60-days mortality, whereas no interaction (Pint = 0.061) between PEEP and AGI grade on 60-days mortality was observed. In the presence of Pplat ≥ 19 cmH2O, the patients with AGI grade III/IV had 60-day mortality rate of 72.2%, significantly higher than those with AGI grade I/II (48.7%, P = 0.018), whereas there were no significant differences (27.9% vs. 33.7%, P = 0.39) in 60-days mortality between AGI grade I/II and III/IV among the patients with Pplat < 19 cmH2O. In comparison with Pplat, DP had a similar interaction (Pint = 0.028) with AGI grade on 60-day mortality. Ventilatory pressure parameters (Pplat and DP) are independent risk factors of AGI grade III/IV. Pplat and DP interact with AGI grade on 60-days mortality, highlighting the importance of optimizing ventilatory pressure parameters to improve gastrointestinal function and survival outcomes of MV patients.Trial registration: ChiCTR-OCS-13003824.

Routine Extracorporeal Life Support in Infarct-Related Cardiogenic Shock: 1-Year Results of the ECLS-SHOCK Trial.

Extracorporeal life support (ECLS) has been increasingly used in the treatment of severe infarct-related cardiogenic shock in the last decade. The randomised ECLS-SHOCK trial demonstrated no benefit of early routine use on 30-day all-cause death. We herein present mid-term results. At 1-year follow-up, there were no significant differences in all-cause or cardiovascular mortality, neurologic outcome, recurrent myocardial infarction, repeat revascularisation and rehospitalisations for heart failure between ECLS and usual medical care.

Association of gastrointestinal symptoms with mortality in patients with severe fever with thrombocytopenia syndrome

BackgroundThe clinical significance of gastrointestinal (GI) symptoms in patients with severe fever and thrombocytopenia syndrome (SFTS) is poorly characterized. This study aimed to determine the prevalence and effect of GI symptoms on the prognosis of patients with SFTS. MethodsThis was a retrospective multi-center cohort study that included hospitalized patients with SFTS from three institutions between October 2010 and August 2022. The risk factors for mortality and intensive care unit (ICU) admission were identified by Cox and logistic regression analyses, respectively. Kaplan-Meier curves were used to analyze the cumulative mortality risk. ResultsAmong 304 patients, the median age was 62.0 years and 51.0% of the patients were male. A total of 202 patients (66.4%) had at least one GI symptom on admission. Diarrhea (69.8%) and nausea (57.4%) were the most common symptoms. Patients with GI symptoms had lower male proportion (46.0% vs. 60.8%, P = 0.015), higher aspartate aminotransferase (177.5 U/L vs. 118.0 U/L, P = 0.010) and lactic dehydrogenase (771.0 U/L vs. 666.5 U/L, P = 0.017) levels than that of patients without GI symptoms. However, there was no significant difference in mortality rates (23.8% vs. 21.6%, P = 0.668) and ICU admission (14.4% vs. 12.7%, P = 0.701) between SFTS patients with and without GI symptoms. Multivariate analysis suggested that GI symptoms at admission were not associated with mortality and ICU admission. ConclusionsGI symptoms are common in patients with SFTS. However, the presence of GI symptoms was not an independent risk factor for poor prognosis.

Impact of timing of ERCP on long term outcomes of ERCP for acute cholangitis – A single center retrospective study

IntroductionAcute cholangitis is a critical medical emergency. The association between the timing of ERCP and clinical outcomes of acute cholangitis is still debated. The current study aims to evaluate whether ERCP within 48 h (urgent) is associated with improved long term clinical outcomes. MethodsThis study is a single-center retrospective analysis of a prospectively maintained database. All patients admitted with acute cholangitis as per Tokyo guidelines at AIG Hospitals, Hyderabad between January 2022 to December 2022 were included. We evaluated the association between urgent ERCP and length of hospital stay, need for reintervention and readmissions, and mortality. ResultsA total of consecutive 301 patients underwent ERCP for acute cholangitis; of which 217 patients (31.3 % females; mean age 54.02 ± 14.9 years) underwent urgent ERCP. The remaining 84 (32.1 % females; mean age 56.56 ± 13.9 years) underwent routine ERCP. Fifty-eight (26.7 %) and 22 (26.2 %) patients with Grade III underwent urgent and routine ERCP respectively. The median (IQR) hospital stay for urgent ERCP was 8.00 (6.00 – 11.00) days and for routine ERCP was 11.00(8.00 – 15.00; p value 0.0001), with similar hospital stay post ERCP (p 0.26). There was no significant difference in mortality upto one year between patients who underwent urgent (22.1 %;48/217) or routine ERCP (31.0 %;26/84, p 0.135). The cox proportional hazard model showed that mortality is independently associated with older age (HR 1.034;95 %CI: 1.013 – 1.054; p 0.001) and malignancy (HR 8.64;95 %CI:4.728 – 15.790; p 0.0001). There was no significant difference between two groups in terms of need for reinterventions and readmissions. ConclusionsUrgent ERCP for acute cholangitis is associated comparable overall mortality, need for reinterventions, and readmissions with decreased total length of hospital stay. There is an unmet need to confirm these findings by randomized controlled studies.

P195 CARDIOVASCULAR OUTCOMES IN PATIENTS WITH AORTIC STENOSIS AND HYPERTENSION UNDERGOING AORTIC VALVE REPLACEMENT

Background and Objective: Aortic valve stenosis (AS) is most common valvular heart disease and in its severe form requires aortic valve replacement (AVR). The prevalence of both AS and arterial hypertension (HTN) increases with age and the conditions therefore often co-exist. Co-existence of AS and HTN is associated with higher global left ventricular (LV) pressure overload, more abnormal LV geometry and function, and more adverse cardiovascular outcome. Management of HTN in AS has historically been associated with prudence and concerns, mainly related to drug-induced potential adverse consequences. We evaluated the cardiovascular outcomes of patients with AS and HTN undergoing to AVR Methods: A retrospective cohort study where all the patients who underwent AVR between 2019- 2024, in a 4-level center in Bogotá, Colombia. A descriptive analysis was performed. Continuous variables were expressed as mean or median with their respective measure of dispersion, standard deviation or interquartile range (ICR), the categorical variables were expressed in proportions and absolute numbers. Results: We analyzed 1043 Patients with moderate/severe AS undergoing AVR, 64.3% (671 with HTN), median age for all of 69.8 years ICR (61.7-77.4) Hypertensive patient being older (72 years p&lt;0.0001). In the HTN group 57.8% were men, and more frequently they had diabetes and dyslipidemia comorbidities (p&lt;0.001) as well as greater baseline renal involvement (p&lt;0.001) comparatively with NO-HTN. In addition, hypertensive patient had better LVEF and were treated with ARA II/IECA (55,6% vs 19.4% p&lt;0.001), beta blockers (60.4% vs 47.3% p&lt; 0.001) and anti-calcium medication (13,1% vs 19,5% p&lt;0.001).Table 1. Cardiovascular outcomes showed greater tendency towards worsening of renal function. There were no statistically significant differences in mortality. Conclusions: AVR is presented as a safe procedure in patients with AS and HTN in developing countries. The institutional results show a safe technique, associated with low mortality rates. Hypertensive patients had more acute kidney injury in the post-surgical period, which leads us to propose kidney protection strategies in this group.

Analysis of the waitlist performance and post-transplant outcomes of lung transplant in elderly recipients in Korea: A nationwide cohort study.

There is a lack of information on the waitlist performance and post-transplant outcomes of lung transplants in elderly recipients in Korea. We retrospectively reviewed and analyzed data from the Korean Network for Organ Sharing database between March 2010 and August 2023. In total, 2574 patients were listed for lung transplantation during the study period, with 511 (19.9%) of them being over 65 years of age. Among these, 188 patients (36.8%) underwent transplantation, while 184 patients (36%) passed away without undergoing transplantation at the time of data extraction. The most prevalent underlying disease on the waitlist was idiopathic pulmonary fibrosis, accounting for 68.1%. The 1-year survival rate was significantly lower in the elderly compared to that in the nonelderly (65.4vs. 75.4%; p=.004). In the multivariate Cox analysis, elderly (hazard ratio [HR], 1.49; 95% CI, 1.14-1.97; p=.004) and a high urgent status at registration (HR, 1.83; 95% CI, 1.40-2.40; p<.001) were significantly associated with post-transplant 1-year mortality. Kaplan-Meier curves demonstrated a significant difference in post-transplant mortality based on the urgency status at enrollment (χ2=8.302, p=.016). Even with the same highly urgent condition at the time of transplantation, different prognoses were observed depending on the condition at listing (χ2=9.056, p=.029). The elderly exhibited worse transplant outcomes than nonelderly adults, with a highly urgent status at registration identified as a significant risk factor. Unprepared, highly urgent transplantation was associated with poor outcomes.

Extralaryngeal Spread in Total Laryngectomy: Comparing the Need for Thyroidectomy.

Objective: At our institution, thyroid preservation during total laryngectomy (TL) varies by surgeon, offering a distinctive dataset to compare disease outcomes in TL patients with or without thyroidectomy. Methods: This retrospective chart review study, conducted at a tertiary referral medical center, comprises patients who underwent TL for laryngeal or hypopharyngeal squamous cell carcinoma from 2014 to 2022. The study includes data on patient demographics, surgeries, pathological staging, tumor subsites, thyroid involvement, and adjuvant therapy. Results: In this study, 147 patients, mostly male (83%) and white (82%), were included. Surgeries comprised 60 hemi thyroidectomies, 35 total or completion thyroidectomies, 48 without thyroid removal, and 4 isthmusectomies. Data analysis compared these 4 groups and the cohort of no thyroid removal (NT) versus any thyroidectomy (T = 99). Among the 99 patients, 27 showed positive gland involvement, primarily due to direct disease extension (26 cases). No significant difference was found in recurrence rates or recurrence-related mortality among the 4 groups or between NT and T (P = .156). However, there was a significant difference in T staging and prognostic staging among the groups and between NT versus T (P = .043). The NT cohort showed a higher likelihood of being T3, while T was more likely to be T4. Conclusion: We found no significant difference in recurrence rates or mortality between TL patients with or without thyroid removal. However, those without thyroid removal often had lower T stages. Notably, 27% of thyroidectomy patients had gland invasion, highlighting the importance of thyroid removal in TL.

Comparison of four aortic bioprostheses: Hancock II vs. St Jude Trifecta vs. Carpentier-Edwards Perimount Magna vs. Magna Ease-mid-term results (COMPARE SAVR study).

In the era of percutaneous aortic valve implantation, biological valves are the preferred prostheses implanted in patients undergoing surgical aortic valve replacement (sAVR). The aim was to present a real-life analysis of mid-term sAVR outcomes for the four aortic bioprostheses: the Hancock II, the Carpentier-Edwards Perimount Magna, the Carpentier-Edwards Perimount Magna Ease and the Trifecta valve. This is a retrospective study based on data from the Polish National Cardiac Surgery Database. The study population comprised of 1,589 consecutive patients, of whom 432 were in the Hancock II group, 356 in the Carpentier-Edwards Perimount Magna group, 427 in the Carpentier-Edwards Magna Ease group, and 374 in the Trifecta group. A comparison of the four groups was performed using analysis of variance (ANOVA) or Kruskal-Wallis test with appropriate post hoc tests (Tukey HSD or Steel-Dwass, respectively). Patients in the Hancock II group were older, had higher New York Heart Association (NYHA) and Canadian Cardiovascular Society (CCS) classes, had lower prevalence of hypertension and hyperlipidemia but higher prevalence of diabetes. The lowest mean valve size was observed in Trifecta group and the highest was in the Magna group (P<0.001). Survival analysis showed no significant differences in in-hospital mortality: 3.9% in Hancock II, 3.1% in Perimount, 3.3% in Magna and 2.1% in Trifecta group. Five-year mortality was significantly higher in Hancock II group (25.7%) compared to the other bioprostheses: 12.1% in Perimount, 9.1% in Magna and 10.70% in Trifecta group respectively. The 5-year mortality rate was significantly higher in the Hancock II group compared to the other bioprostheses. In contrast, Trifecta, Perimount Magna, and Magna Ease had similar 5-year mortality rates.

The Safety of Calcium Channel Blockers in Controlling Blood Pressure During Cardiac Surgery: A Meta-analysis of Random Controlled Trials

Background: Intraoperative hypertension is a very common critical condition in cardiac surgery, which may lead to myocardial ischemia, affect the smooth progress of the operation, and even lead to the death of the patient. Therefore, it is necessary to manage perioperative hypertension in cardiac surgery. At present, there are various types of drugs for hypertension control in clinical practice, and it is necessary to select vasoactive drugs suitable for cardiac surgery. Methods: A systematic search was conducted in PubMed (Medline), Embase, and the Cochrane Library databases to compare the safety of calcium channel blockers and other antihypertensive drugs in controlling hypertension during cardiac surgery, with the search ending in July 2024. For continuous variables, we utilized combined weighted mean difference (WMD) with a 95% confidence interval (CI) and risk ratio (RR) with a 95% confidence interval to assess both efficacy and safety. Results: A total of six randomized controlled trials were included, with a total of 1886 patients. There was no significant difference in mortality between calcium channel blockers and other vasodilators (RR=0.75, 95% CI: 0.45,1.26, P =0.28; I2=0%, P=0.75). Also, there was no significant difference in the incidence of atrial fibrillation (RR=1.09, 95% CI: 0.94,1.26, P=0.26; I2=13%, P=0.33). In addition, there were no significant differences in the incidence of myocardial infarction (RR=0.76, 95% CI: 0.41,1.39, P=0.37; I2=0%, P=0.55) and renal insufficiency (RR=0.92, 95% CI: 0.65,1.31, P=0.66; I2=40%, P=0.19) between the two groups. Finally, there was no significant difference in the incidence of total adverse events between the two groups (RR=1.05, 95% CI: 0.87,1.27, P=0.60; I2=0%, P=0.68). Conclusion: Compared with other vasodilators, there is no significant difference in the safety of calcium channel blockers in controlling blood pressure in cardiac surgery.

Clinical characteristics and outcomes of Australian and Indian ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI)

IntroductionThe incidence of STEMI and subsequent mortality has been reported to be higher in Indian populations compared to developed countries. However, there is limited data directly comparing contemporary primary percutaneous coronary intervention (pPCI) treatment strategies and clinical outcomes for STEMI patients between developed and developing countries. Materials and methodsWe compared population demographics, procedural characteristics, times to reperfusion and mortality in STEMI patients treated with pPCI between two tertiary referral centers in India and Australia respectively over a 3-year period (1st Jan 2017–31st Dec 2019). ResultsA total of 1293 STEMI presentations (896 Indian vs 397 Australian) were included. On average, Indian patients had lower median BMI than Australian patients (BMI 25.4 vs 27.8; p < 0.001), were significantly younger (mean age 56.0 vs 63.2 years; p < 0.001), more likely male (84 % vs 80 %; p = 0.046) and diabetic (48 % vs 18 %); p < 0.001). Radial access (50 % vs 88 %; p < 0.001) and TIMI III flow post PCI was also significantly lower (85 % vs 96 %; p < 0.001) with median door-to-balloon time significantly shorter in the Indian cohort (20mins vs 43mins; p < 0.001); however, median symptom to balloon time was significantly longer (245mins vs 160mins; p < 0.001). No significant differences in 30-day mortality (4.0 % vs 2.8 % Australian; p = 0.209) or 1-year mortality (6.5 % vs 4.3 %; p = 0.120) were observed. ConclusionSignificant differences in demographics and presentation characteristics exist between Indian and Australian STEMI patients treated with pPCI. Indian patients had significantly longer pre-hospital delays and lower achievement of TIMI III flow post PCI, yet shorter in-hospital time to treatment.

Implementation of “Test and Treat” Strategy: Analysis of Deaths of People Living with HIV from 2017 to 2022 in Baise City, China

Background: Acquired immune deficiency syndrome (AIDS) remains a significant public health concern in China. Treatment coverage has been expanded by revising the antiretroviral therapy (ART) for people living with HIV (PLWH). Several years after implementing the new “Test and Treat” strategy, it is essential to evaluate its impact on people living with HIV since its implementation. Objectives: This study was conducted to comprehensively analyze the deaths of PLWH from 2017 to 2022 in Baise City, China. Methods: A retrospective cohort study was conducted to comprehensively analyze the deaths of PLWH in Baise from 2017 to the first half of 2022. The data was acquired from the AIDS Information System (AIDSIS). The all-cause and AIDS-related mortality rates were calculated for PLWH, along with the proportion of specific death causes. Interrupted time series analysis was utilized to examine changes in all-cause mortality pre- and post-implementation of the new strategy. Kaplan-Meier curves were drawn to compare the mortality risk within 1 year of diagnosis between treated and untreated patients, as well as between late discoverers and non-late discoverers. Related factors of death were also analyzed using the Cox proportional hazards regression model. Results: During the observation period, among a total of 8,922 PLWH cases, 1,265 people died, resulting in an all-cause mortality rate of 4.19 per 100 person-years. Acquired immune deficiency syndrome -related deaths numbered 438, accounting for 34.62% of the total deaths, with a mortality rate of 1.45 per 100 person-years. There were 730 non-AIDS-related deaths, representing 57.71%, with a mortality rate of 2.42 per 100 person-years. The overall mortality rate from all causes within 1 year after diagnosis was 5.58 per 100 person-years. No significant difference was identified in the all-cause mortality rate between the periods before and after the implementation of the new strategy. Untreated PLWH and late discoverers exhibited a high risk of death within 1 year of diagnosis. Most deaths were caused by common chronic diseases, while AIDS-related mortality was mainly due to opportunistic infections. Factors such as gender, age at diagnosis, occupation, educational background, ethnic group, infection route, history of ART, and baseline CD4 level were associated with the risk of all-cause mortality and AIDS-related mortality. Conclusions: After the implementation of the “Test and Treat” strategy, no significant difference in mortality among PLWH was recorded in Baise City, China. We recommend that the health department strengthen the testing of PLWH and improve treatment options. Additionally, we suggest encouraging the maintenance of long-term ART treatment and taking measures to prevent and control tuberculosis and common chronic diseases in individuals who are HIV positive.

Gender Disparities in Japanese Interventional Cardiology: Outcomes of Female Operators in Percutaneous Coronary Interventions

BackgroundGender disparity remains a significant global concern in interventional cardiology, and there is a lack of extensive research examining the outcomes of percutaneous coronary interventions (PCIs) performed by female interventionalists. ObjectivesThe aim of this study was to examine the practice patterns and outcomes of PCIs conducted by female interventionalists in Japan. MethodsThis retrospective observational study analyzed data from the Japanese Percutaneous Coronary Intervention registry between January 2019 and December 2021. The primary endpoint was in-hospital mortality and the secondary endpoint was the success rate of PCIs. ResultsA total of 447 female operators (7.3% of all operators) performed 35,211 PCIs (5.3%) during the study period. Female doctors treated a higher percentage of patients with ST-segment elevation myocardial infarction compared with their male counterparts (20.2% vs 17.7%; P = 0.001), whereas male doctors were more likely to perform PCIs for left main disease (4.9% vs 5.9%; P < 0.001) and lesions treated with rotational atherectomy (3.5% vs 4.9%; P < 0.001). The success rate of PCIs was higher for female interventionalists (97.8% vs 97.2%; P < 0.001). After conducting a risk-adjusted analysis, we found no significant difference in in-hospital mortality (adjusted OR: 0.896; 95% CI: 0.78-1.03; P = 0.12), or procedural complications associated with the operator's gender. ConclusionsOverall, female operators exhibited outcomes similar to their male counterparts in terms of adjusted procedural outcomes, and higher crude success rate in certain subgroups. These findings emphasize gender disparities and stress the need to increase gender diversity in interventional cardiology.

Subcutaneous versus Transvenous Implantable Cardioverter Defibrillator in Patients with End-Stage Renal Disease Requiring Dialysis: Extended Long-Term Retrospective Multicenter Follow-Up.

Implantable cardioverter defibrillators (ICD) prevent sudden cardiac death (SCD). Patients with end-stage renal disease (ESRD) requiring dialysis are at a very high risk of infection from cardiac implantable electronic device (CIED) implantation as well as mortality. In the present study, we compared the long-term complications and outcomes between subcutaneous ICD (S-ICD) and transvenous ICD (TV-ICD) recipients. In this retrospective analysis, we analyzed a total of 43 patients with ESRD requiring dialysis who received either a prophylactic S-ICD (26 patients) or a single right ventricular lead TV-ICD (17 patients) at seven experienced centers in Germany. Follow-up was performed bi-annually, at the end of which the data concerning comorbidities and, if applicable, reason for death were checked and confirmed with patients' general practitioner, nephrologist and cardiologist. The median follow up duration was 95.6 months (range 42.8-126.3 months). Baseline characteristics were without noteworthy significant differences between groups. During follow-up (FU), there were significantly more device-associated infections (HR 8.72, 95% confidence interval (CI), 1.18 to 12.85, p < 0.05) and device-associated hospitalizations (HR 10.20, 95% CI 1.22 to 84.61, p < 0.001), as well as a higher cardiovascular mortality (HR 9.17, 95% CI 1.12 to 8.33, p < 0.05), in the TV-ICD group. The number of patients requiring hospitalization for any reason was significantly higher in the TV-ICD group (HR 2.59, 95% CI 1.12 to 6.41, p < 0.05). There was no significant difference in overall mortality (HR 1.92, 95% CI 0.96 to 6.15, p = 0.274). Our data suggest that, in this extended follow-up in seriously compromised renal patients on dialysis, the S-ICD patients have statistically fewer device infections and hospitalizations as well as lower cardiac mortality compared with the TV-ICD cohort.

Maryland's Global Budget Revenue Program and Equitable Access to Esophagectomy for Esophageal Cancer

IntroductionWe evaluated equity in access to esophagectomy after Maryland's 2014 “Global Budget Revenue” (GBR) implementation, which equalizes reimbursement rates irrespective of patient insurance and employs an annual hospital revenue ceiling to incentivize reductions in unnecessary resource utilization. We hypothesized that more traditionally underserved patients would undergo surgical treatment for esophageal cancers after GBR. MethodsUsing Maryland's Health Services Cost Review Commission database, we retrospectively analyzed patient demographics, insurance statuses, inflation-adjusted hospital charges, postoperative outcomes, and discharge dispositions for esophagectomies for neoplasms between 2012 and 2018. ResultsFour hundred eighty six patients were included: 22.0% (107) pre-GBR and 78.0% (379) post-GBR. The proportion of African-American patients increased post-GBR (5.6% versus 12.9%, P = 0.035) and subsequently exhibited year-over-year increases. While not statistically significant, the proportion of Medicaid patients increased from 4.7% to 10.0% (P = 0.085). The post-GBR era also saw patients from 10 new counties, six of which were in Maryland's bottom half of counties ranked by median household income, receive operative esophageal cancer treatment without losing representation from pre-GBR counties. Patient age and sex were comparable between the two groups, and there were no significant differences in mortality or 30-day readmissions. Inflation-adjusted hospital charges and length of hospital stay did not appreciably change post-GBR, including after adjusting for age, comorbidities, and surgical approach. ConclusionsGBR increased access to esophagectomy for African-Americans, those insured by Medicaid, and those from lower socioeconomic status counties. Contrary to prior studies of outpatient and emergency room settings, we found the GBR program's goal of reduction of resource utilization and cost were not apparent in this complex surgical population.
