Changes in blood catecholamines during induction of general anesthesia in patients with post-induction hypotension undergoing laparoscopic cholecystectomy: A single-center prospective cohort study.
BACKGROUND
Post-induction hypotension (PIH) often occurs during general anesthesia induction. This study aimed to investigate blood catecholamine levels during induction of general anesthesia in patients with PIH undergoing laparoscopic cholecystectomy.
METHODS
This prospective study included 557 adult patients who underwent laparoscopic cholecystectomy under general anesthesia. PIH was defined as a greater than 20% decrease in systolic blood pressure from the pre-induction value, a systolic arterial pressure of less than 90 mmHg, or both. Plasma concentrations of epinephrine and norepinephrine during the induction of general anesthesia were determined using enzyme-linked immunosorbent assay. Multivariate logistic regression analysis evaluated the association between the clinical factors and PIH.
RESULTS
Of the 557 patients, 390 had PIH, and the remaining 167 were allocated to the non-PIH group. Changes in blood adrenaline, noradrenaline levels, or both were more pronounced in the PIH than in the non-PIH group (p<0.05). Age, body mass index, a history of hypertension, preoperative systolic blood pressure, and propofol or sufentanil dose were independent predictors of PIH.
CONCLUSION
The changes of blood catecholamines in patients with more stable hemodynamics during the induction of general anesthesia are smaller than that in patients with post-induction hypotension.

INTRODUCTION
In the United States, over one in every ten households experiences food insecurity. Food insecurity is associated with often co-occurring adverse health consequences, including risk for obesity, type 2 diabetes, and hypertension. Within the "Food is Medicine" intervention space, Produce Prescription Programs (PRx) seek to alleviate food insecurity and improve diet and health outcomes by leveraging access to produce through healthcare organizations. Though these programs are burgeoning across the United States, research surrounding their implementation and outreach is limited.
METHODS
This study evaluates the implementation, reach, engagement, and retention of a PRx program piloted in two regions of Georgia (US) from 2020 to 2022. The study included 170 people living with one or more cardiometabolic conditions recruited from clinical sites in metropolitan and rural areas. The program provided pre-packaged produce boxes and nutrition education over six months. We examine participants' baseline demographics, food security status, dietary patterns, and loss to follow-up across contexts (metropolitan and rural). We employ regression analyses and model comparison approaches to identify the strongest predictors of loss to follow-up during the pilot period.
RESULTS
In the pilot period of this program, 170 participants enrolled across rural and metropolitan sites. Of these, 100 individuals (59%) remained engaged for the six-month program. While many individuals met the target criteria of living with or at-risk of food insecurity, not all lived with low or very low food security. Metropolitan participants, males, and those with children in the household had significantly higher odds of loss to follow-up compared to rural participants, females, and those without children in the household. No other significant demographic or household differences were observed.
DISCUSSION
This study demonstrates the potential of PRx programs to enhance food and nutrition security and cardiometabolic health in metropolitan and rural clinical settings. Future research should focus on addressing barriers to engagement and expanding the reach, impact, and sustainability of PRx programs across diverse contexts.

BACKGROUND
The left atrium approach for atrial fibrillation (AF) ablation requires an atrial transseptal puncture that may cause an iatrogenic atrial septal defect (iASD). This study aimed to investigate the incidence and predictors of iASD in catheter ablation, assessed by transthoracic echocardiography (TTE), a relatively non-invasive technique frequently employed in follow-up.
METHODS
This retrospective study included 639 patients (489 male; 60.2 ± 10.7 years) who underwent initial catheter ablation for AF between May 2005 and June 2018. All patients underwent preprocedural transesophageal echocardiography (pre-TEE), preprocedural TTE (pre-TTE), and TTE one day after the procedure (post-TTE). iASD incidence after 6 months (6 M), preprocedural characteristics, and procedure methods were evaluated.
RESULTS
Patent foramen ovale (PFO) was diagnosed in 42 patients (6.6 %) using pre-TEE and in 11 patients using pre-TTE (26.2 % of the patients with PFO in pre-TEE). Among the 597 patients without PFO, 497 underwent 6 M-TTE. iASD was observed in 59.6 % of patients using post-TTE and 4.6 % using 6 M-TTE. In the univariate logistic regression analysis, the total diameter of the sheath through the septum (odds ratio 1.15, p < 0.001) or two sheaths through a single puncture (odds ratio 4.17, p = 0.001) were independent risk factors on iASD incidence in 6 M-TTE. iASD was also more likely to occur via cryoballoon ablation using a larger sheath than radiofrequency catheter ablation.
CONCLUSIONS
iASD was not a rare complication. A larger sheath diameter or two sheaths through a single puncture were associated with the incidence of iASD.

BACKGROUND
Chronic systemic inflammation is associated with mortality in patients with chronic kidney disease, cardiovascular disease, and diabetes. The goal of this study was to examine the relationship between pretransplant inflammatory biomarkers (growth differentiation factor-15 [GDF-15], interleukin-6 [IL-6], soluble tumor necrosis factor receptor-1, monokine induced by gamma interferon/chemokine [C-X-C motif] ligand 9 [MIG/CXCL9], monocyte chemoattractant protein-1, soluble FAS, tumor necrosis factor-α, interleukin-15, and interleukin-1β) and death with function (DWF) after kidney transplantation (KT).
METHODS
We retrospectively measured inflammatory biomarker levels in serum collected up to 1 y before KT (time from blood draw to KT was 130 ± 110 d) in recipients transplanted between January 2006 and December 2018. Kaplan-Meier estimation, Cox regression, and Gradient Boosting Machine modeling were used to examine the relationship between inflammatory biomarkers and DWF.
RESULTS
Our cohort consisted of 1595 KT recipients, of whom 62.9% were male and 83.2% were non-Hispanic White. Over a mean follow-up of 7.4 ± 3.9 y, 21.2% of patients (n = 338) experienced DWF. Patients with the highest quartile levels of GDF-15 (>4766 pg/mL), IL-6 (>6.11 pg/mL), and MIG/CXCL9 (> 5835 pg/mL) had increased rates of DWF, and each predicted mortality independently of the others. When adjusted for clinical factors (age, diabetes, etc), the highest quartile levels of GDF-15 and IL-6 remained independently associated with DWF. Adding inflammatory markers to a clinical Cox model improved the C-statistic for DWF from 0.727 to 0.762 using a Gradient Boosting Machine modeling approach.
CONCLUSIONS
These findings suggest that pre-KT serum concentrations of GDF-15, IL-6, and MIG/CXCL9 may help to risk stratify and manage patients undergoing KT and suggests that chronic inflammation may play a role in mortality in KT recipients.

BACKGROUND
Losing or donating a kidney is associated with risks of developing hypertension and albuminuria. Few studies address mechanisms or interventions. We investigate potential benefits of a K+- alkali-enriched diet and the mechanisms underlying proteinuria.
METHODS
Male Sprague Dawley rats were fed either a 2% NaCl + 0.95% KCl diet (HNa-LK) or a 0.74% NaCl + 3% K+-alkali diet (HK-alk) for 3 wk prior to uninephrectomy then maintained on respective diets for 12 wk. Blood pressure (by tail-cuff), urine, blood and kidney proteins were analyzed Pre- and Post-uninephrectomy.
RESULTS
Pre-uninephrectomy, HK-alk vs. HNa-LK fed rats exhibited similar blood pressures and plasma [K+], [Na+], but lower proximal (NHE3, NBCe1, NaPi2) and higher distal (NCC, ENaC, pendrin) transporter abundance, a pattern facilitating K+ and HCO3- secretion. Post-uninephrectomy, single nephron GFR rose 50% and Li+ clearance doubled with both diets; in HK-alk vs HNa-LK: the rise in blood pressure was less and ammoniagenesis was lower, abundance of proximal tubule transporters remained lower, ENaC-α fell and NCCp rose consistent with K+ conservation. Post-uninephrectomy, independent of diet, albuminuria increased 8-fold and abundance of endocytic receptors was reduced (megalin by 44%, dab2 by 25-35%) and KIM-1 was increased.
CONCLUSIONS
The K-alkali-enriched diet blunted post-uninephrectomy hypertension and facilitated acid clearance by suppressing proximal Na+ transporters and increasing K+ -alkali secretion. Further, uninephrectomy associated proteinuria could be attributed, at least in part, to elevated SNGFR coupled to downregulation of megalin which reduced fractional protein endocytosis and Vmax.

PURPOSE
Despite systemic thrombolysis, a few patients with high-risk pulmonary embolism (PE) remain hemodynamically unstable. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a considerable lifesaving therapy but systemic thrombolysis before cannulation could carry a high risk of hemorrhage and alter the prognosis.
METHODS
Between June 2012 and June 2023, we retrospectively analyzed from three intensive care units in Sorbonne University, ECMO-related complications and 90-day mortality for high-risk PE patients who received ECMO without previous systemic thrombolysis compared to those cannulated after systemic thrombolysis failure. Hospital discharge survivors were assessed for long-term health-related quality of life and echocardiographic evaluations.
RESULTS
72 high-risk PE patients [median age 48 (37-61) years, Simplified Acute Physiology Score II (SAPS II) 74 (60-85)] were placed on VA-ECMO for 5 (5-7) days. 31 (43%) patients underwent pre-ECMO thrombolysis (thrombolysis ECMO group, T +) compared to 41 patients (57%, no thrombolysis ECMO group, T-). There was more pre-ECMO cardiac arrest in the thrombolysis ECMO group (94% vs. 67%, p = 0.02). Ninety-day survival was not different between groups (39% vs 46%, log-rank test, p = 0.31). There was no difference in severe hemorrhages (61% vs 59%, p = 1). Twenty-five over 28 patients attended follow-up at a median time of 69 (52-95) months. Long-term quality of life was acceptable and none of them experienced chronic thromboembolic pulmonary hypertension.
CONCLUSIONS
Ninety-day survival and bleeding events rates did not differ in patients treated with VA-ECMO after systemic thrombolysis compared to those who were not. Recent systemic thrombolysis, as a single parameter, should not be considered as a contraindication for VA-ECMO in high-risk PE.

BACKGROUND
We conducted a comparative analysis of hypertension prevalence, progression, and treatment in two Finnish population-based cohorts comprising older adults born 20 years apart. The study covered data from pre- and post-HYVET Study eras and spanned the onset of the COVID-19 pandemic.
METHODS
All 70-year-old home-dwelling citizens of Turku, in Southwest Finland, were invited to participate in the survey in 1990 (1920-born TUVA cohort) and in 2010 (1940-born UTUVA cohort) with a 25-year follow-up plan. The analyses included those with available data for systolic and diastolic blood pressure (BP), yielding 1015 TUVA and 888 UTUVA participants at baseline. Biomarkers associated with BP were analysed with - and chi-square tests.
RESULTS
At baseline, 83.4% of TUVA and 74.3% of UTUVA participants had uncontrolled BP, with respective antihypertensive medication usage at 36.0% and 55.9% ( < .001 for both between-cohort differences). Systolic BP exhibited an inverted U-shaped trajectory, with TUVA initially 7.8 mmHg higher at 155.4 mmHg than UTUVA ( < .001). However, by the ages 80-82, the difference in systolic BP trajectories between the cohorts was attenuated to 4.0 mmHg ( = .03). Diastolic BP differences were less clinically significant. UTUVA demonstrated higher use of all five conventional antihypertensive categories than TUVA ( ≤ .02 for all categories).
CONCLUSIONS
In the early years of older adulthood, the 1940-born cohort showed a positive trend in hypertension management, yet maintained a 74.3% baseline rate of uncontrolled BP. Furthermore, by the ages 81-82, the benefits observed over the 1920-born cohort had lessened, influenced by the COVID-19 pandemic or other lasting factors. Heightened efforts to improve hypertension treatment in older adults remain crucial in the post-HYVET era.

BACKGROUND
Given the pervasive issues of obesity and diabetes both in Puerto Rico and the broader United States, there is a compelling need to investigate the intricate interplay among BMI, pregestational, and gestational maternal diabetes, and their potential impact on the occurrence of congenital heart defects (CHD) during neonatal development.
METHODS
Using the comprehensive System of Vigilance and Surveillance of Congenital Defects in Puerto Rico, we conducted a focused analysis on neonates diagnosed with CHD between 2016 and 2020. Our assessment encompassed a range of variables, including maternal age, gestational age, BMI, pregestational diabetes, gestational diabetes, hypertension, history of abortion, and presence of preeclampsia.
RESULTS
A cohort of 673 patients was included in our study. The average maternal age was 26 years, within a range of 22 to 32 years. The mean gestational age measured 39 weeks, with a median span of 38 to 39 weeks. Of the 673 patients, 274 (41%) mothers gave birth to neonates diagnosed with CHD. Within this group, 22 cases were linked to pre-gestational diabetes, while 202 were not; 20 instances were associated with gestational diabetes, compared to 200 without; and 148 cases exhibited an overweight or obese BMI, whereas 126 displayed a normal BMI.
CONCLUSION
We identified a statistically significant correlation between pre-gestational diabetes mellitus and the occurrence of CHD. However, our analysis did not show a statistically significant association between maternal BMI and the likelihood of CHD. These results may aid in developing effective strategies to prevent and manage CHD in neonates.

Review
This paper explores global COVID-19 treatment and containment strategies in 108 countries worldwide, specifically the correlation between COVID-19 deaths and the countries' vaccination rates. Comparison of data across states, provinces, territories, and countries relied upon a common method to evaluate data regarding the impact of COVID-19 policies in the last three years. Data from nine different databases were analyzed to determine if there were correlations between the percentage of countrywide COVID-19 deaths/population and countries' percent vaccinated. Secondary outcome measures include the effect of other variables on COVID-19 death rates per country population, including health expenditures and annual income per capita, COVID-19 tests per 1000 people, stringency index (a measure of each country's containment strategies), hydroxychloroquine/ivermectin scores (measure country use), hypertension, obesity, diabetes, and geographic locations. COVID-19 vaccination rates ranged from 0-99% in 108 countries. Bivariate analysis demonstrates the following independent variables to correlate with COVID-19 deaths/population (Spearman correlation coefficient, p value): countrywide COVID-19 vaccination rates (moderate relationship, r=0.39, < .001); healthcare expenditures per capita per annum (US dollars) (moderate relationship, r=0.46, < .001), net annual income per capita (moderate relationship, r=0.50, < .001), COVID-19 tests per 1000 country population (moderate relationship, r=0.36, < .003); stringency index per country (moderate relationship, r=0.28, < .003); hydroxychloroquine index (negative relationship, r= 0.15, = .125); and ivermectin index (negative relationship, r=0.23 = .018). The authors found that the higher the percentage of a country's vaccination rate, stringent containment strategies, mass testing, etc., moderately correlated with higher COVID-19 death rates/population. Future studies are required to explore the findings of this study fully.

INTRODUCTION
Gestational diabetes mellitus (GDM) is defined as diabetes diagnosed in the second or third trimester of pregnancy that was not clearly overt diabetes before gestation. Unrecognized and untreated GDM confers significantly greater maternal and fetal risk, which is largely related to the degree of hyperglycemia. The specific risks of diabetes in pregnancy include but are not limited to, spontaneous abortion, pre-eclampsia, fetal anomalies, macrosomia, neonatal hypoglycemia, hyperbilirubinemia, and respiratory distress syndrome. Additionally, GDM is also implicated in long-term metabolic derangements in the offspring in the form of obesity/overweight, hypertension, dysglycemia, insulin resistance, and dyslipidemias later in life. To determine the prevalence of anthropometric and metabolic derangements in children between 1 and 5 years of age, born to women with GDM.
METHODS
This hospital-based cross-sectional study was conducted between November 2019 and November 2021 at our Pediatric Endocrine Clinic. Women were diagnosed as having GDM based on the American Diabetes Association Criteria (2019). History regarding the treatment of the GDM (diet only/diet and medical treatment) and detailed physical examination, including anthropometry and blood pressure, were recorded. Blood samples were collected from children for the estimation of their metabolic profile.
RESULTS
Overweight, obesity, and severe obesity were present in 18 (11.3%), 2 (1.3%), and 2 (1.3%) children, respectively. Hypertension was found in 21 (19.4%) children. Elevated LDL, triglyceride, and total cholesterol were seen in 3 (1.9%), 84 (52.5%), and 1 (0.6%) children, respectively. Impaired fasting glucose (IFG) was found in 6 (3.8%) children, while 27 (16.9%) subjects were found to be having impaired glucose tolerance after OGTT. Insulin resistance was found in 30 (18.8%) children. GDM mothers with a higher BMI tended to have children with a higher BMI (correlation coefficient, r = .414, < .001). Higher serum triglyceride levels (r = -0.034, = 0.672) were recorded in children, irrespective of the BMI of their mothers. There was no significant correlation of maternal BMI with blood pressure (r = -0.134, = 0.091) or with HOMA-IR (r = 0.00, = 0.996) in children. However, mothers with a higher BMI had children with statistically higher fasting blood glucose (r = +0.339, = <0.001) as well as blood glucose 2 hours after OGTT (r = +0.297, = <0.001). This positive correlation of maternal BMI with the glucose metabolism of their offspring was observed for both male and female genders.
CONCLUSION
Children of women with GDM had a higher BMI, and the mode of treatment for GDM did not lead to differences in childhood BMI. The higher BMI of a GDM mother is associated with altered glucose metabolism in their offspring. Deranged levels of triglyceride across the gender were not found to be statistically significant. This has implications for future metabolic and cardiovascular risks in targeting this group for intervention studies to prevent obesity and disorders of glucose metabolism as one potential strategy to prevent adverse metabolic health outcomes.
