Purpose Despite the need for advanced hemodynamic monitoring, the role of the pulmonary artery catheter (PAC) in cardiogenic shock (CS) remains controversial due to conflicting evidence from previous studies. Material and Methods This single-center retrospective study utilized the MIMIC-IV database to assess the impact of PAC use on 30-day in-hospital mortality and clinical outcomes in CS patients admitted between 2008 and 2019. Propensity score matching (PS) and inverse propensity treatment weighting (IPTW) were employed to adjust for baseline differences. The primary outcome was 30-day in-hospital mortality; secondary outcomes included hospital and ICU length of stay and complications. Cox proportional hazard ratio analyses were performed to evaluate the association between PAC use and mortality outcomes. Results The final cohort consisted of 1940 adult CS patients, with 134 receiving PAC and 1806 not. PAC use significantly reduced 30-day in-hospital mortality (PS-matched HR 0.57, 95% CI: 0.39-0.83; IPTW HR 0.58, 95% CI: 0.35-0.96) but was associated with longer hospital stays (16.47 vs 12.37 days) and ICU stays (9.26 vs 7.52 days). Conclusion PAC use in CS patients was associated with improved short-term survival but also with longer hospitalization and potential complications, underscoring the need for careful patient selection and further research.

Background: Invasive management strategies for myocardial infarction (MI) and multivessel coronary artery disease (MV-CAD) include complete revascularization (successful revascularization of all coronary artery lesions or segments ≥1.5 mm in diameter with ≥50% diameter stenosis) and incomplete revascularization (including culprit-only revascularization). However, non-culprit lesion management strategy in elderly patients remains ambiguous due to a lack of representation of this cohort in randomized trials (RCTs) and higher cardiovascular complication risks. Methods: We performed a meta-analysis comparing clinical outcomes of elderly individuals (age ≥65 years) with MI and MV-CAD submitted to complete vs. incomplete (including culprit-only) percutaneous coronary intervention (PCI). The outcomes of interest were all-cause death, cardiovascular mortality, recurrent MI, and any revascularization. Pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated using a random-effects model. Results: Thirteen studies (3 RCTs, 1 post hoc analysis of previous RCT, and 9 observational studies) with a total of 12,289 patients were included. Complete revascularization (CR) was performed in 5,232 patients, while 7,057 patients underwent incomplete revascularization (IR). The mean age was 80.46 years for CR and 80.73 years for IR and the mean durations of follow-ups ranged from 12-78 months. As compared to IR, the CR group was associated with significantly lower risk of all-cause mortality (OR 0.59, 95% CI 0.49 to 0.71, p<0.0001) (Figure 1), cardiovascular mortality (OR 0.56, 95% CI 0.40 to 0.77, p=0.0005), recurrent MI (OR 0.62, 95% CI .47 to 0.81, p=0.0005) (Figure 2), and any revascularization (OR 0.47, 95% CI 0.26 to 0.86, p=0.01). Conclusion: Among elderly patients with MI and MV-CAD, CR is associated with a lower risk of all-cause mortality, cardiovascular mortality, recurrent MI, and any revascularization.

Background: Ambiguity surrounds invasive management of non-ST-segment elevation myocardial infarction (NSTE-MI) in older adults (≥70 years), and the number of elderly patients undergoing invasive treatment in clinical practice remains relatively low. Data comparing the efficacy of invasive versus conservative medical management for NSTEMI in this population is conflicting due to the under-representation or exclusion of the older population from randomized controlled trials (RCTs). Methods: We performed a meta-analysis of RCTs to evaluate the long-term outcomes of invasive versus conservative medical strategies in older patients with NSTEMI. Random effects meta-analysis was conducted to estimate the odds ratio (OR) with 95% CI for the individual endpoints of all-cause mortality, cardiovascular (CV) mortality, recurrent myocardial infarction (MI), unplanned revascularization, and readmission for cardiovascular causes. Results: A total of nine RCTs with 4,336 patients (Invasive: 2,368; Control: 1,968) with median follow-ups ranging from 6-63.6 months were included. Compared with a conservative strategy, an invasive strategy was associated with a significantly decreased risk of recurrent MI (OR 0.62, 95% CI 0.47-0.81; p<0.001) (Figure 1) and unplanned revascularization (OR 0.38, 95% CI 0.25-0.56; p<0.001). There was no difference in all-cause mortality (OR 0.81, 95% CI 0.39-1.35; p=0.42) (Figure 2), CV mortality (OR 0.72, 95% CI 0.43-1.23; p=0.23), or readmission for cardiovascular causes (OR 1.21, 95% CI 0.63-2.33; p=0.57) between invasive and conservative management strategies. Conclusion: In older patients ≥70 years old with NSTE-MI, an invasive strategy reduced the risk of recurrent MI and revascularization when compared with conservative management. However invasive strategy did not offer any benefit in mortality or cardiac-cause related readmission over conservative management.

The efficacy and safety of extracorporeal membrane oxygenation (ECMO) support during transcatheter aortic valve replacement (TAVR) remains unknown. We conducted a meta-analysis to compare benefit and risk of ECMO in TAVR patients. Bibliographic databases were searched from inception to January 1, 2024. Included studies involved patients ≥18 years old undergoing TAVR and using ECMO emergently or prophylactically. Mortality and procedure success were primary outcomes. Peri- or postoperative complications were the secondary outcomes. We identified 11 observational studies, including 2,275 participants (415 ECMO and 1,860 non-ECMO). The unadjusted mortality risk in ECMO-supported patient was higher than non-ECMO patients (odds ratio [OR] 1.73). The mortality unadjusted risk remained high (OR 3.89) and statistically significant for prophylactic ECMO. Prophylactic ECMO had lower mortality risk compared with emergent ECMO (OR 0.17). Extracorporeal membrane oxygenation-supported patients had lower procedural success rate (OR 0.10). Extracorporeal membrane oxygenation patients undergoing TAVR had significantly increased risk of bleeding (OR 3.32), renal failure (OR 2.38), postoperative myocardial infarction (OR 1.89), and stroke (OR 2.32) compared with non-ECMO patients. Clinical results are not improved by ECMO support in patients with high-risk TAVR. Prophylactic ECMO outperforms emergent. Overall, ECMO support increases mortality and postoperative complications. Transcatheter aortic valve replacement outcomes may improve with prophylactic ECMO in high-risk situations.

Abstract Objective: Global concern exists for workplace violence against healthcare workers (HCWs), especially in low and middle-income nations. This violence includes physical, verbal, or sexual abuse and has a significant impact despite initiatives like Occupational Safety and Health Administration (OSHA) guidelines. We conducted a study in Kenya to address this issue. Methods: We did a cross-sectional survey that collected responses during June 6th to August 9th, 2022, focused on healthcare professionals in Kenya within the global ViSHWaS study. Violence against healthcare professionals in multiple Kenyan counties was analysed, The study reached participants through social media, emails, and other channels using a snowball sampling technique. Results: The survey included 1,458 HCWs, primarily females (66.5%), aged 36-45 (42.4%), and of African race, representing 40 counties, with the majority from Nairobi (28.9%) and working in government academic (35.5%) and private academic institutions (20.6%). Most had over 11 years of healthcare experience (64.4%), and registered nurses were the most common cadre (27.8%). Approximately half (49.9%) reported experiencing violence, with verbal violence (80.6%) and emotional abuse (78.6%) being common. Online harassment was reported by only 3.5%, mainly on Facebook (63.2%), involving hate speech (92.1%). Patients or their relatives were the most common aggressors (44.7%), while supervisors accounted for 12.5%. The frequency of violence varied, and 80.2% noted an increase after the COVID-19 pandemic. Only 41.2% of incidents were reported. Most were familiar with safety guidelines (93.6%). Self-violence was associated with familiarity with guidelines, concern about violence, preparedness, and night shifts, while colleague violence was associated with age, gender, race, work experience, training, preparedness, and night shifts. Conclusion: Our Kenya-based cross-sectional sub-analysis highlights that a significant number of HCWs experienced violence, especially during the COVID-19 pandemic, which negatively affected job satisfaction. Although most HCWs were familiar with OSHA guidelines, there were difficulties in their practical implementation.

Objective To provide insights into the nature, risk factors, impact and existing measures for reporting and preventing violence in the healthcare system. The under-reporting of violence against healthcare workers (HCWs) globally highlights the need for increased public awareness and education. Methods The Violence Study of Healthcare Workers and Systems study used a survey questionnaire created using Research Electronic Data Capture (REDCap) forms and distributed from 6 June to 9 August 2022. Logistic regression analysis evaluated violence predictors, including gender, age, years of experience, institution type, respondent profession and night shift frequency. A χ 2 test was performed to determine the association between gender and different violence forms. Results A total of 5405 responses from 79 countries were analysed. India, the USA and Venezuela were the top three contributors. Female respondents comprised 53%. The majority (45%) fell within the 26–35 age group. Medical students (21%), consultants (20%), residents/fellows (15%) and nurses (10%) constituted highest responders. Nearly 55% HCWs reported firsthand violence experience, and 16% reported violence against their colleagues. Perpetrators were identified as patients or family members in over 50% of cases, while supervisor-incited violence accounted for 16%. Around 80% stated that violence incidence either remained constant or increased during the COVID-19 pandemic. Among HCWs who experienced violence, 55% felt less motivated or more dissatisfied with their jobs afterward, and 25% expressed willingness to quit. Univariate analysis revealed that HCWs aged 26–65 years, nurses, physicians, ancillary staff, those working in public settings, with >1 year of experience, and frequent night shift workers were at significantly higher risk of experiencing violence. These results remained significant in multivariate analysis, except for the 55–65 age group, which lost statistical significance. Conclusion This global cross-sectional study highlights that a majority of HCWs have experienced violence, and the incidence either increased or remained the same during the COVID-19 pandemic. This has resulted in decreased job satisfaction.

Background and Objectives: Bartter syndrome (BS) is a rare group of autosomal-recessive disorders that usually presents with hypokalemic metabolic alkalosis, occasionally with hyponatremia and hypochloremia. The clinical presentation of BS is heterogeneous, with a wide variety of genetic variants. The aim of this systematic review was to examine the available literature and provide an overview of the case reports and case series on BS. Materials and Methods: Case reports/series published from April 2012 to April 2022 were searched through Pubmed, JSTOR, Cochrane, ScienceDirect, and DOAJ. Subsequently, the information was extracted in order to characterize the clinical presentation, laboratory results, treatment options, and follow-up of the patients with BS. Results: Overall, 118 patients, 48 case reports, and 9 case series (n = 70) were identified. Out of these, the majority of patients were male (n = 68). A total of 21 patients were born from consanguineous marriages. Most cases were reported from Asia (73.72%) and Europe (15.25%). In total, 100 BS patients displayed the genetic variants, with most of these being reported as Type III (n = 59), followed by Type II (n = 19), Type I (n = 14), Type IV (n = 7), and only 1 as Type V. The most common symptoms included polyuria, polydipsia, vomiting, and dehydration. Some of the commonly used treatments were indomethacin, potassium chloride supplements, and spironolactone. The length of the follow-up time varied from 1 month to 14 years. Conclusions: Our systematic review was able to summarize the clinical characteristics, presentation, and treatment plans of BS patients. The findings from this review can be effectively applied in the diagnosis and patient management of individuals with BS, rendering it a valuable resource for nephrologists in their routine clinical practice.

Background and Objective: The association of non-alcoholic fatty liver disease (NAFLD) and metabolic-associated fatty liver disease (MAFLD) with intensive care unit (ICU) admissions and the need for mechanical ventilation and disease severity in COVID-19 patients. Material and Methods: A systematic literature review was conducted on the databases: Cochrane, Embase, PubMed, ScienceDirect, and the Web of Science from January 2019 to June 2022. Studies evaluating MAFLD using laboratory methods, non-invasive imaging, or liver biopsy were included. The study protocol was registered in PROSPERO (ID CRD42022313259), and PRISMA guidelines were followed. The NIH quality assessment tool was used for quality assessment. RevMan version 5.3 software was used for pooled analysis. A sensitivity analysis was performed to assess the result’s stability. Results: A total of 37,974 patients from 17 studies were assessed for the association between MAFLD and ICU admission. A total of 3396 COVID-19 patients required ICU admission: 1236 (20.41%) in the MAFLD group and 2160 (6.77%) in the non-MAFLD group. The odds ratio was 1.86 for ICU admission, p = 0.007, and a (95% CI) of [1.18–2.91]. A total of 37,166 patients from 13 studies were included in the need for invasive mechanical ventilation analysis. A total of 1676 patients required mechanical ventilation: 805 in the MAFLD group (14.20% of all MAFLD patients) and 871 patients in the non-MAFLD group (2.76% of all non-MAFLD patients). The odds ratio was 2.05, p = 0.02, and a (95% CI) of [1.12–3.74]. A total of 5286 patients from 14 studies were included in the COVID-19 disease severity analysis. Severe COVID-19 was seen in 1623 patients, with 33.17% (901/2716) of MAFLD patients and 28.09% (722/2570) of non-MAFLD patients having severe disease. The odds ratio was 1.59 for disease severity, p = 0.010, and a (95% CI) of [1.12–2.26]. Conclusions: Our meta-analysis suggests that there are significantly increased odds of ICU admissions, a need for invasive mechanical ventilation, and disease severity in MAFLD patients who acquire COVID-19.
