Vasopressin Initiation as a Second-Line VasoPressor in Early Septic Shock (VISPSS).

BACKGROUND: Vasopressin is recommended as a second-line vasoactive agent for the management of septic shock; however, a paucity of data to guide its optimal use remains. The aim was to evaluate the effect of time-to vasopressin initiation and norepinephrine (NE) dose at vasopressin initiation on clinical outcomes in patients presenting with septic shock. METHODS: This was a multi-centered, retrospective, observational study conducted in patients with septic shock. Patients were divided into 2 groups: patients initiated on vasopressin when NE-equivalent dose (NEE) < 0.25 mcg/kg/min or ≥ 0.25 mcg/kg/min. The primary outcome was time-to-vasopressor discontinuation (hours). Secondary outcomes included 28-day in-hospital mortality, intensive care unit (ICU) length of stay (LOS), fluid balance after 72 hours, and the change in NEE at 12 hours. RESULTS: A total of 302 patients were included in this study. After propensity-score matching, 73 patients in each group were identified for analysis. There was no significant difference in the time-to-vasopressor discontinuation (hours) between the groups (88.8 [55-187.5] vs 86.7 [47-172]); p = 0.7815). Fluid balance (mL) at 72 hours was significantly lower when vasopressin was initiated at NEE < 0.25 mcg/kg/min (1769 [71-7287] vs 5762 [1463-8813]; p = 0.0077). A multivariable linear regression showed shorter time to shock resolution with earlier vasopressin initiation, defined as within 4 hours (p < 0.05). CONCLUSION: In this propensity-score matched cohort, vasopressin initiation at NEE < 0.25 mcg/kg/min was not associated with shorter vasopressor duration. There was a lower fluid balance at 72 hours when vasopressin was initiated at lower NE doses.

Impact of intravenous calcium with diltiazem for atrial fibrillation/flutter in the emergency department.

OBJECTIVE: The purpose of this study was to evaluate the effect of early intravenous (IV) calcium on systolic blood pressure (SBP) when administered with IV diltiazem in subjects with atrial fibrillation (AF) or flutter (AFL) with rapid ventricular response (RVR) in the Emergency Department (ED). METHODS: This was a multicenter, retrospective cohort study that evaluated adults admitted to the ED with documented AF or AFL, heart rate (HR) > 120 bpm, SBP 90 to 140 mmHg, and received treatment with IV diltiazem for rate control. The primary outcome was the change in SBP 60 min (+/- 30 min) after initial IV diltiazem administration. Secondary outcomes included time to initial rate control (HR < 100 bpm), time to sustained rate control (HR < 100 bpm for 3 h), change in HR, rates of hypotension, bradycardia, hypercalcemia, and line extravasation within 24 h of initial diltiazem administration. RESULTS: There were 198 subjects in the diltiazem monotherapy group and 56 subjects in the diltiazem with calcium group meeting the inclusion criteria. The primary outcome, median change in SBP 60 min after initial IV diltiazem administration, was similar between groups (-2 mmHg vs -1.5 mmHg; p = 0.642), but this difference was not statistically significant. All secondary outcomes were found to be similar between groups. Although not statistically significant, hypotension occurred more often in the diltiazem with calcium group (20.2% vs 32.1%; p = 0.060) while bradycardia occurred more often in the diltiazem monotherapy group (4.5% vs 0%; p = 0.213). In terms of achieving rate control, the administration of calcium with diltiazem did not significantly change the time to initial rate control (1.4 h vs 1.8 h; p = 0.141) or time to sustained rate control (7.9 h vs 7.7 h; p = 0.570) compared to diltiazem alone. CONCLUSIONS: In the setting of AF/AFL with RVR, administration of IV calcium with IV diltiazem did not show a significant impact on clinical or safety outcomes compared to IV diltiazem monotherapy.

Atracurium Versus Cisatracurium in the Treatment of Acute Respiratory Distress Syndrome.

Background: Neuromuscular blocking agents are one of the few medication classes that have demonstrated a clinical benefit in patients with severe acute respiratory distress syndrome (ARDS). However, most literature utilized cisatracurium, and utilization of atracurium is limited to 1 small study. Objective: The purpose of this study was to provide further evidence comparing the safety and efficacy of atracurium versus cisatracurium for the treatment of ARDS. Methods: This multicenter, retrospective, observational cohort noninferiority study was conducted at 3 hospitals within a tertiary health care system. We included subjects diagnosed with ARDS who received either atracurium or cisatracurium for at least 12 hours. The primary outcome measured the change in PaO2/FiO2 (P/F) ratio from baseline to 48 hours after initiation. Results: Baseline characteristics were similar between groups except for a higher median age and a higher proportion of subjects who were COVID-positive in the atracurium group. There were also some noted differences in the baseline P/F ratios. In a multivariable model adjusting for baseline characteristics, the change in the P/F ratio for atracurium was noninferior to cisatracurium at 24, 48, and 72 hours. A significant cost reduction, measured as cost per patient per day, was seen with the use of atracurium ($14.81-$25.16 vs $33.86-$41.91). Conclusion: Atracurium appears to be a safe and cheaper alternative agent in the management of ARDS.

Use of fibrinolytics for the management of massive pulmonary embolism in a patient with a history of subdural hemorrhage.

INTRODUCTION: Management of massive pulmonary embolism in patients with hemodynamic instability encompasses the use of fibrinolytics. Use of fibrinolytic therapy is currently recommended in this patient population by ACCP, AHA, and EHA if treatment benefit outweighs the risk of bleeding. There is currently no data challenging or exploring the risk of using fibrinolytic therapy for the management of massive PE in patients with a history of intracranial hemorrhage. CASE PRESENTATION: A 38-year old female with suspected massive pulmonary embolism was admitted with a chief complaint of chest pain and right leg pain. Shortly after a confirmatory CT of bilateral PE, the patient had multiple cardiac arrests along with severe shock that led to a general agreement among the team to proceed with IV and then catheter-directed TPA as well as thrombectomy. Following fibrinolytic therapy, the patient was started on a heparin drip along with epinephrine for hemodynamic support. CT chest angiography showed the resolution of emboli following treatment with the fibrinolytic agent. CT of the head taken approximately 24 h post tPA initiation was used to rule out intracranial hemorrhage or other complications resulting from tPA administration. CONCLUSION: In patients with a history of intracranial hemorrhage, catheter guided fibrinolytic and thrombectomy may be effective treatment options of massive pulmonary embolism.

The Effect of Fasting on Cardiovascular Diseases: A Systematic Review.

Among the leading causes of morbidity, disability, and death worldwide are cardiovascular diseases (CVDs). Their risk factors usually include a variety of factors associated with cardiometabolic disorders. Many public health organizations prioritize the prevention of CVDs and encourage people to maintain a healthy lifestyle. It has been shown that fasting and a healthy diet can promote weight loss and improve cardiometabolic health in various animal species. We want to know the impact of fasting on CVDs. The topic is examined in this systematic review. We looked through a wide range of online sources, including PubMed, Cochrane Library, and Google Scholar, to find randomized controlled trials (RCTs) that looked into the connection between CVDs and fasting. We included human research that has been published in English in peer-reviewed publications in the last five years, and then we screened by the title, abstract, and full-text accessibility. We picked the final 10 articles for quality assessment using Cochrane Collaboration's tool for risk-of-bias assessment of RCTs. The findings suggest that fasting is beneficial in lowering the cardiovascular risk of a population. This result holds for all types of fasting used as an intervention in the clinical trials we reviewed. The result is pronounced when fasting regimens are combined with a regular exercise routine. More comprehensive data will come from larger-scale clinical trials and case-control studies, and a thorough examination of all the potential health impacts of fasting is warranted.

Gut Microbiota and Colorectal Cancer: An Umbrella Review of Methodological Trends and Clinical Correlations.

In this umbrella review, we analyze the effect of gut microbiota on the development and progression of colorectal cancer (CRC), a global health challenge. Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines, we searched multiple databases for the most relevant systematic reviews and meta-analyses from 2000 to 2023. We identified 20 articles that met our inclusion criteria. The findings include the identification of specific microbiota markers, such as Fusobacterium nucleatum, for potential early diagnosis and improvement of disease treatment. This thorough study not only establishes the connection between microbiota and CRC but also provides valuable knowledge for future research in developing microbiome-centered treatments and preventive methods.

Treatment Efficacy of Plasmapheresis Versus Intravenous Immunoglobulin in Guillain-Barré Syndrome Management: A Systematic Review.

Guillain-Barré syndrome (GBS) is a rare and debilitating autoimmune disorder that affects the peripheral nervous system. Although the exact etiology of GBS is still unknown, it is thought to be triggered by a preceding gastrointestinal infection in most of the cases. Clinical manifestations include limb weakness, areflexia, and sensory loss that can further progress to neuromuscular paralysis affecting the respiratory, facial, and bulbar functions. Both plasmapheresis (PE) and intravenous immunoglobulin (IVIG) have shown effectiveness in the treatment of GBS, but it is still unclear which treatment approach is superior in terms of therapeutic efficacy. This systematic review acts per Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. For appropriate studies and research, we searched PubMed, PubMed Central (PMC), Medical Literature Analysis and Retrieval System Online (MEDLINE), Science Direct, and Google Scholar. Screening of articles was performed based on relevance and inclusion and exclusion criteria. To check for bias, we used relevant quality appraisal tools. Initially, we found 2454 articles. After removing duplicates and irrelevant papers, we finalized 31 studies based on titles, abstracts, and reading entire articles. We excluded 14 studies because of poor quality; the remaining 17 papers were included in this review. IVIG is equally efficacious as PE in improving primary outcomes and secondary outcomes. IVIG showed a slight advantage over PE in reducing the need for mechanical ventilation (MV) and hospital stay duration. However, in children, PE demonstrated a slight edge in improving secondary outcomes. PE was associated with a slightly higher risk of adverse events and post-treatment worsening symptoms compared to IVIG. IVIG is considered more user-friendly with a significantly lower patient discontinuation rate than PE. IVIG treatment was found to be significantly more expensive than PE.

Impact of oral naloxegol vs subcutaneous methylnaltrexone in treatment of opioid-induced constipation in the hospital setting.

PURPOSE: Peripherally acting µ-opioid receptor antagonists (PAMORAs) are indicated to treat laxative-refractory opioid-induced constipation (OIC). While several PAMORAs exist, no head-to-head comparative data are available. This study evaluated the efficacy, safety, and cost of oral naloxegol vs subcutaneous methylnaltrexone for OIC in the hospital. METHODS: In this multicenter retrospective chart review, patients who received oral naloxegol or subcutaneous methylnaltrexone as an inpatient were included if they were at least 18 years old, were still admitted to the hospital 48 hours after the first PAMORA dose, and either had an outpatient opioid prescription or received at least 30 morphine milligram equivalents in the 24 hours before the first PAMORA dose. The primary outcome was achievement of a bowel movement (BM) within 48 hours of the first dose. Secondary outcomes included a BM in 24 hours, time to the first BM, antimotility agent use, PAMORA cost per patient, and use of a second PAMORA due to failure of the first agent. RESULTS: A total of 330 patients were included with 2:1 allocation (220 patients receiving methylnaltrexone vs 110 patients receiving naloxegol). Baseline characteristics were similar between the groups, except for body mass index and weight. Naloxegol met a prespecified noninferiority margin of 15% in production of a BM within 48 hours (risk difference, -4.6%; 90% confidence interval, -13.6% to 4.5%; P = 0.028). Achievement of a BM within 24 hours and time to first BM were also noninferior. Antimotility agent use was higher with naloxegol, naloxegol cost $193.16 less per patient, and 2 patients switched from naloxegol to methylnaltrexone. CONCLUSION: Oral naloxegol may be an effective, cost-efficient alternative to subcutaneous methylnaltrexone for treatment of OIC in the hospital setting.

Patient satisfaction with post-operative surgical services and associated factors at Addis Ababa City government tertiary hospitals' surgical ward, cross-sectional study, 2022.

Introduction: patient satisfaction is an attitude resulting from a person's general orientation towards the total experience of health care. The study was done with the aim of evaluating post-operative patient satisfaction level with the quality of service provided at the surgical wards; determining how much factors related to physicians, nursing, laboratory, and information provision service influence satisfaction level; and determining factors impacting patient satisfaction level. Methods: a hospital-based quantitative cross-sectional study design was conducted in six Addis Ababa City Government tertiary hospitals from November 4th to December 13th, 2022. Patients who had major operations done at the government hospitals from November 21st to December 5th, 2022, were included in the study population. A pre-tested, structured, and Amharic-version questionnaire was used to interview patients. A bivariate and multivariate logistic regression model was used to identify the variables that had an association with the dependent variable. P-values less than 0.05 were considered statistically significant. Results: a total of 287 patients participated in the research, providing a response rate of 95%. Of the total participants, 144 were males (50.8%) and 143 were females (49.5%). The overall patient satisfaction level with surgical ward service is 96.2%. The level of patient satisfaction with nursing services is 94.8%, with physician's services it is 98.6%, with the facility it is 92.3%, and with the provision of information about post-operative complications it is 69.7%. Those who have above-first-degree educational status are less satisfied (66.7%) than patients with other levels of educational status. Only the patients' residency showed a small level of association (r= 0.145, p=0.014) with overall patient satisfaction with surgical ward service among the demographic components. The two variables that are strongly correlated with patient satisfaction are the adequacy of the time ward nurses spent with patients during evaluation and treatment (r = 0.503, p = 0.000) and adequate nurses' response to patients' calls (r = 0.498, p = 0.000). Post-operative patient satisfaction with surgical ward nursing service, physician service, hospital facilities, and the provision of information about post-op complications explain about 40.9 percent of the variation in the overall patient satisfaction with post-op care provided at the surgical ward. Patient satisfaction with nursing service has more significant effect with overall patient satisfaction than the other variables (ß = 0.266, p =0.0002). Conclusion: post-operative patients at Addis Ababa City Government Tertiary Hospitals expressed a very high degree of satisfaction with the care they received in the surgical wards. The study also found that patients were generally less satisfied with the information they were given on drugs, side effects, and available treatment options. Another factor identified in the study that caused unhappiness was the unavailability of some pharmacy and laboratory services.

Tenecteplase use in the management of acute ischemic stroke: Literature review and clinical considerations.

PURPOSE: Several research articles have been published within the last decade comparing the use of tenecteplase to alteplase in ischemic stroke management. Prior reporting on the comparative therapeutic efficacy and safety profiles of tenecteplase and alteplase is reviewed. SUMMARY: Tenecteplase is a variant of native tissue-type plasminogen activator, which rapidly promotes thrombolysis by catalyzing formation of the serine protease plasmin. Tenecteplase has theoretical advantages over alteplase as it has greater fibrin specificity and has a longer half-life than alteplase. This allows the administration of a single bolus over 5 to 10 seconds, as opposed to a bolus followed by a 1-hour infusion with alteplase. While currently approved by the Food and Drug Administration for the treatment of ST-segment elevation myocardial infarction, tenecteplase has also been studied in the treatment of acute ischemic stroke and has extensive data for this off-label indication. The most comprehensive trials to date evaluating the use of tenecteplase in acute ischemic stroke include the TNK-S2B, Australian TNK, ATTEST, Nor-Test, and EXTEND-IA TNK trials. Findings from these randomized controlled studies suggest that tenecteplase is at least as efficacious as alteplase in terms of neurological outcomes. The majority of these studies also reported a trend toward improved safety profiles with the use of tenecteplase. CONCLUSION: Current clinical evidence shows that tenecteplase is not inferior to alteplase for the treatment of ischemic stroke and suggests that tenecteplase may have a superior safety profile. Furthermore, tenecteplase also has practical advantages in terms of its administration. This can potentially lead to a decrease in medication errors and improvement in door to thrombolytic time.
