RESUMO
BACKGROUND: Postoperative urinary retention is a common concern after total joint arthroplasty (TJA) and can cause discomfort, incontinence and, if left untreated, myogenic changes to the bladder. However, overdiagnosis of postoperative urinary retention by bladder scans may lead to unnecessary interventions and delayed discharges. The purpose of this study was to compare the safety of two bladder management protocols following TJA. METHODS: From January 3, 2022 to April 29, 2022, 519 consecutive patients operated on by thirteen surgeons underwent routine postoperative bladder scanning (standard protocol). From February 28, 2022 to April 29, 2022, a new protocol was introduced by three surgeons in 209 consecutive patients using a specific algorithm (selective protocol) so that only symptomatic patients had bladder scans. The primary outcome of interest was catheterization rate. Chi-square and Students t-tests were used for analyses. There were 37.7% of patients in the selective group who received scans. RESULTS: Times to catheterization, readmissions, emergency department visits, and straight catheterization rates (15.0 versus 14.8% P = .999) were similar. More scans in the selective group resulted in intervention (39.2 versus 15.0%, P < .001). Prevoid volumes were higher in the selective protocol (608 versus 448 mL, P < .001). Postvoid volumes were similar (233 versus 223 mL, P = .497). There was one readmission for a urinary tract infection in the standard group and no urinary-related readmissions in the selective group. CONCLUSION: The selective protocol had a higher rate of same day discharge, fewer bladder scans, and did not lead to increased rates of urinary-related complications. These findings suggest that selective bladder scanning for symptomatic patients can be safely instituted for TJA patients.

BACKGROUND: Early and correct diagnosis of ST-segment elevation myocardial infarction (STEMI) is crucial for providing timely reperfusion therapy. Patients with ischemic symptoms presenting with ST-segment elevation on the electrocardiogram (ECG) are preferably transported directly to a catheterization laboratory (Cath-lab) for primary percutaneous coronary intervention (PPCI). However, the ECG often contains confounding factors making the STEMI diagnosis challenging leading to false positive Cath-lab activation. The objective of this study was to test the performance of a standard automated algorithm against an additional high specificity setting developed for reducing the false positive STEMI calls. METHODS: We included consecutive patients with an available digital prehospital ECG triaged directly to Cath-lab for acute coronary angiography between 2009 and 2012. An adjudicated discharge diagnosis of STEMI or no myocardial infarction (no-MI) was assigned for each patient. The new automatic algorithm contains a feature to reduce false positive STEMI interpretation. The STEMI performance with the standard setting (STD) and the high specificity setting (HiSpec) was tested against the adjudicated discharge diagnosis in a retrospective manner. RESULTS: In total, 2256 patients with an available digital prehospital ECG (mean age 63 ± 13 years, male gender 71%) were included in the analysis. The discharge diagnosis of STEMI was assigned in 1885 (84%) patients. The STD identified 165 true negative and 1457 true positive (206 false positive and 428 false negative) cases (77.3%, 44.5%, 87.6% and 17.3% for sensitivity, specificity, PPV and NPV, respectively). The HiSpec identified 191 true negative and 1316 true positive (180 false positive and 569 false negative) cases (69.8%, 51.5%, 88.0% and 25.1% for sensitivity, specificity, PPV and NPV, respectively). From STD to HiSpec, false positive cases were reduced by 26 (12,6%), but false negative results were increased by 33%. CONCLUSIONS: Implementing an automated ECG algorithm with a high specificity setting was able to reduce the number of false positive STEMI cases. However, the predictive values for both positive and negative STEMI identification were moderate in this highly selected STEMI population. Finally, due the reduced sensitivity/increased false negatives, a negative AMI statement should not be solely based on the automated ECG statement.

The use of the radial artery (RA) as a conduit in coronary artery bypass grafting (CABG) has been steadily increasing since the early 1990s and based on the most recent data may well become the standard of care for patients with multivessel coronary artery disease requiring multiple arterial grafts. The transradial access (TRA) approach for cardiac catherization has also increased steadily in use by interventional cardiologists owing to its reduction in bleeding and vascular complications when compared with the femoral approach and is now considered the preferred arterial access. However, prior use of TRA for cardiac catherization is a contraindication for the use of the RA for CABG because of high rates of structural damage to the vascular wall and potential for graft failure. In this issue of the Journal of Cardiac Surgery Clarke et al. examine the RA of two patients who had TRA for coronary angiography 8 and 12 years prior and note that both patients had chronic injury with dissection and obstruction of the lumen secondary to fibrosis suggesting that TRA causes long-term and irreversible damage rendering them unsuitable as conduits for CABG.

INTRODUCTION: Early removal of urinary catheters is an effective strategy for catheter-associated urinary tract infection (CAUTI) prevention. We hypothesized that a nurse-directed catheter removal protocol would result in decreased catheter utilization and CAUTI rates in a surgical trauma intensive care unit (STICU). METHODS: We performed a retrospective, cohort study following implementation of a multimodal CAUTI prevention bundle in the STICU of a large tertiary care center. Data from a 19-month historical control were compared to data from a 15-month intervention period. Pre- and postintervention indwelling catheter utilization and CAUTI rates were compared. RESULTS: Catheter utilization decreased significantly with implementation of the nurse-driven protocol from 0.78 in the preintervention period to 0.70 in the postintervention period (P < .05). As a result of the bundle, the CAUTI rate declined significantly, from 5.1 to 2.0 infections per 1000 catheter-days in the pre- vs postimplementation period (Incident Rate Ratio [IRR]: 0.38, 95% confidence interval: 0.21-0.65). CONCLUSIONS: Implementation of a nurse-driven protocol for early urinary catheter removal as part of a multimodal CAUTI intervention strategy can result in measurable decreases in both catheter utilization and CAUTI rates.

BACKGROUND: Peripheral venous cannulation is considered a routine procedure, yet 50% of first attempt insertions fail, necessitating repeat insertion attempts. Identification of children with difficult intravenous access (DIVA) can help promote prompt escalation to an appropriately skilled clinician. OBJECTIVE: To describe current international practice regarding the identification and management of children with DIVA, and to systematically review clinical tools and clinical pathways for children with DIVA. METHODS: A cross-sectional, international survey; followed by a systematic review and critical appraisal of clinical pathways using the Appraisal of Guidelines for Research Evaluation (AGREE) II checklist. RESULTS: A total of 148 clinicians from eight countries completed the survey. The majority were nurses (n = 92; 62%), practicing as vascular access specialists (n = 27; 18%). Twenty-three respondents (16%) reported using a DIVA tool, of which the DIVA Score was most common (n = 5; 22%). Five clinical pathways were identified from the survey and review. Based on the AGREE II domains, pathways generally scored well for scope and purpose, and for clarity of presentation areas. Information on the rigor of development and editorial independence was infrequently detailed. Based on AGREE II findings, one pathway was recommended for clinical practice, and four were recommended for use with modification. CONCLUSIONS: Resources for the identification and escalation of children with DIVA are not standardized or consistently used. Further work is needed to streamline processes for DIVA identification and escalation to the appropriate clinician, with technology-assisted insertion capability. This will enhance patient experiences and reduce harm from multiple insertion attempts. CLINICAL RELEVANCE: Multiple failed insertion attempts come at great cost to the child, family, and healthcare service. Early identification and management of the child with DIVA can ensure prompt escalation and management, improving the patient and family experience.

Accumulating evidence shows that ultrasound (US) guidance improves effectiveness and safety of central venous catheter (CVC) placement. Several international guidelines therefore recommend the use of US for placement of CVCs. However, surveys show that the landmark-based technique is still widely used, while the percentage of physicians using US is increasing less than expected. The goal of this study was to investigate current practice for central venous catheterization in anaesthesiology and intensive care in the Netherlands, identify barriers for further implementation of US guidance and to evaluate whether personality traits are associated with the choice of technique. We conducted a web-based national survey, distributed among members of the Dutch societies of anaesthesiology (NVA) and intensive care (NVIC). The survey contained questions regarding physician and hospital characteristics, frequency of US use and reasons for use or non-use, as well as the NEO-FFI-3, a validated, translated questionnaire to characterize personality traits according to the 'Big Five' concept. Response rate was 22% (506/2291), of which 400 had also the personality questionnaire complete. Ultrasound guidance was used always or almost always in 68%; barriers for US use were working in a non-academic non-teaching hospital, providing cardiac anaesthesia and more years of physician experience. Reasons for not using US were perceived lack of benefit, increased procedure time, lack of US equipment and fear of loss of landmark technique skills. 13% of respondents had never experienced a complication during CVC placement, and 67% knew of a complication occurring the past year at their department. Ultrasound was thought not to be able to prevent the complication in half of these cases. Of the personality traits, only neuroticism and extraversion showed a minor positive association with US guidance. A majority of anaesthesiologists and intensivists uses US guidance for CVC placement, but a significant proportion of physicians still prefers the landmark technique. Most arguments from respondents against US guidance can be challenged. Personality traits most likely do not play a major role in the acceptance of US guidance for central venous catheterization. A potential intervention to increase US use could be formalizing local hospital policies mandating compliance with US guidance. Future research can perhaps focus on cognitive biases that currently limit more widespread use of US guidance.

PURPOSE: To evaluate safety and efficacy of botulinum toxin A injections in the urethral striated sphincter in patients with difficulties to perform self-intermittent catherization. METHODS: In this prospective study, 12 patients suffering from upper motor neuron diseases (8 multiple sclerosis, 2 myelitis, 1 brain injury, 1 multi system atrophy) and with difficulties to perform self-intermittent catherization, defined by a ICDQ score>1 (Intermittent Catheterization Difficulty Questionnaire) have had injections of 100U BOTOX® under EMG guidance in the urethral striated sphincter, for a total of 15 injections. Evaluations consisted of two questionnaires (ICDQ and PGI-A, Patient Global Improvement) 30 days after the injection. RESULTS: 30 days after the injection, ICDQ was improved with a mean decrease of the total score of 7.8 (SD=5.9, P<0,001). In the same manner, all the patients were improved with a mean PGI-A score of 2.3. In 73.3 % of cases, the PGI-A score was equal to 2 (improvement=much better), and in 20 % it was equal to 3 (improvement=a little better). CONCLUSIONS: Botulinum toxin A injections in the urethral striated sphincter in patients with difficulties to perform self-intermittent catherization seem to safe and effective. LEVEL OF EVIDENCE: 4.

Early reperfusion therapy is crucial and the standard of care for the management of acute ST-elevation myocardial infarction (STEMI). We report a case of STEMI with unloading followed by more delayed reperfusion, which challenges current clinical practice. It also highlights the importance of more translational research to better understand STEMI on a mechanistic level including the crucial role of mitochondria and anaerobic respiration during vessel occlusion and ischemia. This can also help in preventing post-myocardial infarction complications such as reperfusion injury, which leads to the development of heart failure.
RESUMO
A 57-year-old African-American male presented with urinary retention secondary to a history of balanitis xerotica obliterans (BXO) concurrent with penile carcinoma. BXO, characterized by chronic, sclerosing inflammation of the male external genitalia, presents significant clinical challenges due to its progressive nature and potential for complications. The patient experienced recurrent episodes of urinary retention, leading to multiple hospital visits and disease progression, prompting a comprehensive evaluation and intervention. The patient's medical history revealed a complex array of comorbidities, including penile carcinoma secondary to BXO, urethral strictures, and meatal stenosis. Clinical assessment, including bedside bladder ultrasound and laboratory investigations, confirmed urinary retention secondary to urethral stricture, necessitating urological consultation. Management strategies involved Foley catheter placement, urethral dilation, and pharmacological interventions for pain management. Subsequent follow-up and imaging evaluations identified an increased risk of carcinoma development, highlighting the importance of surveillance and early intervention in patients with BXO. This case report highlights the intricate clinical manifestations and therapeutic considerations encountered in managing BXO and its associated pathologies.
RESUMO
Background: Fluids, solutes and immune cells have been demonstrated to drain from the brain and surrounding structures to the cervical lymph vessels and nodes in the neck via meningeal lymphatics, nasal lymphatics and/or lymphatic vessels associated with cranial nerves. A method to cannulate the efferent cervical lymph duct for continuous cervical lymph fluid collection in rodents has not been described previously and would assist in evaluating the transport of molecules and immune cells from the head and brain via the lymphatics, as well as changes in lymphatic transport and lymph composition with different physiological challenges or diseases. Aim: To develop a novel method to cannulate and continuously collect lymph fluid from the cervical lymph duct in rats and to analyze the protein, lipid and immune cell composition of the collected cervical lymph fluid. Methods: Male Sprague-Dawley rats were cannulated at the carotid artery with or without cannulation or ligation at the cervical lymph duct. Samples of blood, whole lymph and isolated lipoprotein fractions of lymph were collected and analyzed for lipid and protein composition using commercial kits. Whole lymph samples were centrifuged and isolated pellets were stained and processed for flow cytometry analysis of CD3+, CD4+, CD8a+, CD45R+ (B220) and viable cell populations. Results: Flow rate, phospholipid, triglyceride, cholesterol ester, free cholesterol and protein concentrations in cervical lymph were 0.094 ± 0.014 mL/h, 0.34 ± 0.10, 0.30 ± 0.04, 0.07 ± 0.02, 0.02 ± 0.01 and 16.78 ± 2.06 mg/mL, respectively. Protein was mostly contained within the non-lipoprotein fraction but all lipoprotein types were also present. Flow cytometry analysis of cervical lymph showed that 67.1 ± 7.4% of cells were CD3+/CD4+ T lymphocytes, 5.8 ± 1.6% of cells were CD3+/CD8+ T lymphocytes, and 10.8 ± 4.6% of cells were CD3-/CD45R+ B lymphocytes. The remaining 16.3 ± 4.6% cells were CD3-/CD45- and identified as non-lymphocytes. Conclusion: Our novel cervical lymph cannulation method enables quantitative analysis of the lymphatic transport of immune cells and molecules in the cervical lymph of rats for the first time. This valuable tool will enable more detailed quantitative analysis of changes to cervical lymph composition and transport in health and disease, and could be a valuable resource for discovery of biomarkers or therapeutic targets in future studies.

INTRODUCTION: Clean intermittent catheterization (CIC) is a mainstay in the management of neurogenic bladder. OBJECTIVE: To assess the effect of CIC on urinary tract infection and upper renal tract function in pediatric patients with neurogenic bladder, and the influence of duration of CIC on these variables. STUDY DESIGN: A retrospective study was performed in 67 pediatric patients with neurogenic bladder who started CIC between 2014 and 2019 at our institution. The febrile urinary tract infection (fUTI) rate, renal pelvis diameter (measured by antero-posterior renal pelvis diameter, APPD), bladder wall thickness (BWT) on ultrasound, and creatinine level at 6 months and 12 months of CIC were compared with baseline in all patients. The grade of vesicoureteral reflux (VUR) at 12 months of CIC were also compared with baseline. RESULTS: There were no significant differences compared with baseline after 6 months of CIC in the rate of fUTI, APPD, and BWT (p > 0.05); however, all of these parameters significantly improved after 12 months of CIC (p < 0.05). The VUR grade was significantly reduced after 12 months of CIC(p = 0.03). There was no significant change in serum creatinine level with any duration of CIC (both p > 0.05). DISCUSSION: Continuing CIC for more than 6 months had a beneficial influence on protecting the upper urinary tract. Complications of CIC, such as recurrent fUTI and lower urinary tract trauma, are more likely to occur in the early stage of CIC due to poor technique by the caregivers and poor patient compliance underscoring the importance of caregiver education. Study limitations include the retrospective nature and small sample size. CONCLUSION: CIC for less than 6 months may have limited influence on renal protection; however, a longer duration of CIC (12 months) resulted in significant improvement in outcomes. This study demonstrates the importance of proper caregiver education to establish standardized CIC techniques and to improve CIC quality.

Oral treprostinil has been shown to improve exercise capacity and delay disease progression in patients with pulmonary arterial hypertension (PAH), but its effects on hemodynamics are not well-characterized. The FREEDOM-EV trial was a Phase III, international, placebo-controlled, double-blind, event-driven study in 690 participants with PAH who were taking a single oral PAH therapy. FREEDOM-EV demonstrated a significantly reduced risk for clinical worsening with oral treprostinil taken three times daily and did not uncover new safety signals in PAH patients. Sixty-one participants in the FREEDOM-EV trial volunteered for a hemodynamics sub-study. Pulmonary artery compliance (PAC), a ratio of stroke volume to pulmonary pulse pressure, significantly increased from Baseline to Week 24 in the oral treprostinil group compared with the placebo group (geometric mean 26.4% active vs. -6.0% placebo; ANCOVA p=0.007). There was a significant increase in cardiac output in the oral treprostinil group compared to the placebo group (geometric mean 11.3% active vs. -6.4% placebo; ANCOVA p=0.005) and a corresponding significant reduction in pulmonary vascular resistance (PVR) (geometric mean -21.5 active vs. -1.8% placebo; ANCOVA p=0.02) from Baseline to Week 24. These data suggest that increased compliance contributes to the physiological mechanism by which oral treprostinil improves exercise capacity and delays clinical worsening for patients with PAH.

Pediatric cardiology (PC) is a rapidly advancing specialty addressing a large population of children as well as adults with congenital heart disease. It requires huge technical and financial resources; therefore, establishing, maintaining, and developing such services in limited resource settings are challenging. A PC program that includes clinical aspects, echocardiography, diagnostic and interventional cardiac catheterization and cardiac surgery, and rheumatic heart disease control was established in Sudan in 2004. There are currently three public centers with facilities to evaluate and treat children with heart disease: two in Khartoum and one in Wad Medani. Major obstacles include the shortage of trained personnel and operation rooms, the deficiency of intensive care facilities, and the financial burden of interventional procedures. This paper details the establishment and progress of the program, its challenges, potential solutions, and future perspectives for PC programs in Sudan and African countries.
RESUMO
Takotsubo cardiomyopathy (TC), an acute cardiac event is often associated with acute emotional stress, usually in the setting of cardiovascular risk factors. This case report attempts to review one of the triggers of TC beer potomania-induce hyponatremia with imaging findings that shows the link between severe hyponatremia and TC.
RESUMO
BACKGROUND: Given the associated morbidity, mortality, and financial consequences of catheter associated urinary tract infections (CAUTIs), efforts should be made to mitigate the risk. We sought to describe, and report results for a post-catheter removal bladder management protocol focused on decreasing catheter reinsertion, catheter days, and overall CAUTI risk. METHODS: This was a quality improvement initiative implemented over a 3-month period at a single urban, tertiary health care center. Patients with an indwelling urinary catheter deemed eligible for removal were followed and cared for according to the study protocol. Rates of catheter reinsertion, catheter days, and assessment of CAUTI risk were compared between cohorts. RESULTS: A total of 173 patients were eligible for protocol enrollment. Catheter reinsertion rate was 16% during the pilot, compared to 21% and 27% for the historical cohorts, (P = .02). The mean number of catheter day's during the study was 1.4 days, compared to 9.5 and 5.6 days in the historical cohorts (P = .004). Catheter hours (OR 1.010 95% CI 1.005 - 1.015 P < .0001.) was a predictor of catheter reinsertion during the pilot. CONCLUSIONS: Our protocol resulted in a reduction of catheter reinsertion rates and number of catheter days. Expansion of this protocol to a larger patient cohort is required.

Background: Pulmonary arterial hypertension secondary to atrial septal defect (ASD) is an important determinant of morbidity and mortality in defect closure. We aimed to compare perioperative outcome between preoperative borderline and low pulmonary vascular resistance index (≥4â WU.m2 and <4â WU.m2, respectively) in surgical closure of secundum atrial septal defect with concomitant pulmonary arterial hypertension. Methods and results: This was a single-center retrospective cohort study between January 2015 and January 2020. We classified patients with low and borderline PVRI who underwent ASD closure and recorded the perioperative outcomes. Results: We analyzed a total of 183 patients with atrial septal defect and pulmonary arterial hypertension; 92 patients with borderline PVRI and 91 patients with low PVRI. Borderline pulmonary vascular resistance index was not associated with increased risk of postoperative mortality (p = 0.621; OR0.48, 95% CI 0.04-5.48), but associated with higher risk of overall morbidity in bivariate analysis (p = 0.002; OR3.28, 95% CI 1.5-6.72). Multivariate analysis showed positive association of borderline pulmonary vascular resistance index (p = 0.045; OR2.63, 95% CI 1.02-6.77) and preoperative tricuspid valve gradient ≥64â mmHg (p = 0.034; OR2.77, 95% CI 1.08-7.13) with overall morbidity. Conclusion: There is no difference in incidence of in-hospital mortality between preoperative borderline and low pulmonary vascular resistance index patients. However, preoperative borderline pulmonary vascular resistance index and tricuspid valve gradient ≥64â mmHg are associated with increased overall morbidity after surgical closure in secundum atrial septal defect patients with pulmonary arterial hypertension.
RESUMO
BACKGROUND: The prevalence of Rheumatic Mitral Stenosis (MS) has significantly changed over the last decades. We intend to examine patient demographics, Echocardiographic characteristics, procedural success rates, and complications throughout 30-years. METHODS: We conducted a single-center descriptive observational study. The study population consists of patients undergone percutaneous balloon mitral valvuloplasty (PBMV) at Emek Medical Center in Israel from January 1990 to May 2019. RESULTS: Four hundred seventeen patients underwent PBMV during the study period and were eligible for the study. Age did not change significantly over time (p = 0.09). The prevalence of Male and patients who were smoking and had multiple comorbidities such as hypertension, dyslipidemia, ischemic heart disease, and chronic kidney disease became increases over time (p = 0.02, p = 0.02, p = 0.001, p = 0.01, p = 0.02, and p = 0.001, respectively). Wilkins score and all its components increased over time, and the total score was higher in females (p = 0.01). Seventy-nine (18.9%) patients had complications. The rate of complications did not change over decades. Patients with Wilkins score > 8, post-procedural MR of ≥2, and post-procedural MVA < 1.5 had the highest risk for the need of Mitral valve replacement (MVR) surgery in 2 years following PBMV (3.64, 4.03, 2.44, respectively, CI 95%, p < .0001 for all). The median time in these patients was 630 days compared to 4-5 years in the entire population. Patients with Post-procedural MR of ≥2 and post-procedural MVA < 1.5 had ten times risk for developing heart failure (HR 9.07 and 10.06, respectively, CI 95%, P < .0001). CONCLUSION: Our research reveals trends over time in patients' characteristics and echocardiographic features. Our study population consists of more male patients with multiple comorbidities and more complex and calcified valvular structures in the last decade. Wilkins score > 8, post-procedural MR of ≥2, and post-procedural MVA < 1.5 cm2 were in-depended predictors for the time for surgery and heart failure hospitalization.

BACKGROUND: This case report describes a subclavian vein cannulation that inadvertently led to an arterial puncture with the catheter tip radiologically seen at the level of the aorta. This case emphasizes the importance of postprocedural imaging and the disadvantages of not using ultrasound guidance in central venous catheterization. CASE PRESENTATION: A 24-year-old Caucasian man with diabetes mellitus type 1 presented himself to the emergency department due to abdominal pain accompanied by nausea and vomiting. The patient's vital signs revealed blood pressure of 84/53 mmHg, heart rate of 103 beats per minute, respiratory rate of 18 breaths per minute, and temperature of 98.2 °F (36.7 °C). On physical examination, he was found to have dry oral mucosa with poor skin turgor, with diagnostics showing that he was in diabetic ketoacidosis after running out of insulin for 2 days. The patient was transferred to the intensive care unit to receive a higher level of care. Unfortunately, due to difficulty of peripheral line placement, only a gauge-22 cannula was secured at the left dorsum of the hand. Efforts to replace the current peripheral line were unsuccessful, and a decision to perform a central vein cannulation via the internal jugular vein was made. This was futile as well due to volume depletion, prompting a subsequent right subclavian vein route attempt. The procedure inadvertently punctured the arterial circulation, leading to the catheter tip being visible at the level of the aorta on postprocedure X-ray. The subclavian line was immediately removed with no adverse consequences for the patient. A right femoral line was successfully placed, and continuous management of the diabetic ketoacidosis ensued until normalization of the high anion gap was achieved. CONCLUSION: Utilization of real-time ultrasound guidance via the subclavian approach could have allowed for direct visualization of needle insertion to the anatomical structures, guidewire location, and directionality, all of which can lead to decreased complications and improved cannulation success compared with the landmark technique. A leftward direction of the catheter seen on postprocedural X-rays should raise high suspicion of inadvertent catheter placement and immediate correction. This complication should have been prevented if ultrasound guidance had been used.
