Abstract
BACKGROUND Ischemic stroke (IS) is an uncommon but severe complication in patients undergoing percutaneous coronary intervention (PCI). Despite significant morbidity and economic cost associated with post PCI IS, a validated risk prediction model is not currently available. AIMS We aim to develop a machine learning model that predicts IS after PCI. METHODS We analyzed data from Mayo Clinic CathPCI registry from 2003 to 2018. Baseline clinical and demographic data, electrocardiography (ECG), intra/post-procedural data, and echocardiographic variables were abstracted. A random forest (RF) machine learning model and a logistic regression (LR) model were developed. The receiver operator characteristic (ROC) analysis was used to assess model performance in predicting IS at 6-month, 1-, 2-, and 5-years post-PCI. RESULTS A total of 17,356 patients were included in the final analysis. The mean age of this cohort was 66.9 ± 12.5 years, and 70.7% were male. Post-PCI IS was noted in 109 patients (.6%) at 6 months, 132 patients (.8%) at 1 year, 175 patients (1%) at 2 years, and 264 patients (1.5%) at 5 years. The area under the curve of the RF model was superior to the LR model in predicting ischemic stroke at 6 months, 1-, 2-, and 5-years. Periprocedural stroke was the strongest predictor of IS post discharge. CONCLUSIONS The RF model accurately predicts short- and long-term risk of IS and outperforms logistic regression analysis in patients undergoing PCI. Patients with periprocedural stroke may benefit from aggressive management to reduce the future risk of IS.

EClinicalMedicine 2023; 60:102023. [PMID: 37304498 PMCID: PMC10250158 DOI: 10.1016/j.eclinm.2023.102023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 05/11/2023] [Accepted: 05/11/2023] [Indexed: 06/13/2023] Open
Abstract
Background We aimed to define clinical and cost-effectiveness of a Day Care Approach (DCA) alternative to Usual Care (UC, comparison group) within the Bangladesh health system to manage severe childhood pneumonia. Methods This was a cluster randomised controlled trial in urban Dhaka and rural Bangladesh between November 1, 2015 and March 23, 2019. Children aged 2-59 months with severe pneumonia with or without malnutrition received DCA or UC. The DCA treatment settings comprised of urban primary health care clinics run by NGO under Dhaka South City Corporation and in rural Union health and family welfare centres under the Ministry of Health and Family welfare Services. The UC treatment settings were hospitals in these respective areas. Primary outcome was treatment failure (persistence of pneumonia symptoms, referral or death). We performed both intention-to-treat and per-protocol analysis for treatment failure. Registered at www.ClinicalTrials.gov, NCT02669654. Findings In total 3211 children were enrolled, 1739 in DCA and 1472 in UC; primary outcome data were available in 1682 and 1357 in DCA and UC, respectively. Treatment failure rate was 9.6% among children in DCA (167 of 1739) and 13.5% in the UC (198 of 1472) (group difference, -3.9 percentage point; 95% confidence interval (CI), -4.8 to -1.5, p = 0.165). Treatment success within the health care systems [DCA plus referral vs. UC plus referral, 1587/1739 (91.3%) vs. 1283/1472 (87.2%), group difference 4.1 percentage point, 95% CI, 3.7 to 4.1, p = 0.160)] was better in DCA. One child each in UC of both urban and rural sites died within day 6 after admission. Average cost of treatment per child was US$94.2 (95% CI, 92.2 to 96.3) and US$184.8 (95% CI, 178.6 to 190.9) for DCA and UC, respectively. Interpretation In our population of children with severe pneumonia with or without malnutrition, >90% were successfully treated at Day care Clinics at 50% lower cost. A modest investment to upgrade Day care facilities may provide a cost-effective, accessible alternative to hospital management.

Abstract
BACKGROUND Atrioventricular block requiring permanent pacemaker (PPM) implantation is an important complication of transcatheter aortic valve replacement (TAVR). Application of machine learning could potentially be used to predict pre-procedural risk for PPM.
AIM To apply machine learning to be used to predict pre-procedural risk for PPM.
METHODS A retrospective study of 1200 patients who underwent TAVR (January 2014-December 2017) was performed. 964 patients without prior PPM were included for a 30-d analysis and 657 patients without PPM requirement through 30 d were included for a 1-year analysis. After the exclusion of variables with near-zero variance or ≥ 50% missing data, 167 variables were included in the random forest gradient boosting algorithm (GBM) optimized using 5-fold cross-validations repeated 10 times. The receiver operator curve (ROC) for the GBM model and PPM risk score models were calculated to predict the risk of PPM at 30 d and 1 year.
RESULTS Of 964 patients included in the 30-d analysis without prior PPM, 19.6% required PPM post-TAVR. The mean age of patients was 80.9 ± 8.7 years. 42.1 % were female. Of 657 patients included in the 1-year analysis, the mean age of the patients was 80.7 ± 8.2. Of those, 42.6% of patients were female and 26.7% required PPM at 1-year post-TAVR. The area under ROC to predict 30-d and 1-year risk of PPM for the GBM model (0.66 and 0.72) was superior to that of the PPM risk score (0.55 and 0.54) with a P value < 0.001.
CONCLUSION The GBM model has good discrimination and calibration in identifying patients at high risk of PPM post-TAVR.

Safety and efficacy of balloon angioplasty compared to stent-based-strategies with pulmonary vein stenosis: A systematic review and meta-analysis. World J Cardiol 2023; 15:64-75.

Abstract
BACKGROUND Pulmonary vein stenosis (PVS) is an uncommon but known cause of morbidity and mortality in adults and children and can be managed with percutaneous re-vascularization strategies of pulmonary vein balloon angioplasty (PBA) or pulmonary vein stent implantation (PSI).
AIM To study the safety and efficacy outcomes of PBA vs PSI in all patient categories with PVS.
METHODS We performed a literature search of all studies comparing outcomes of patients evaluated by PBA vs PSI for PVS. We selected all published studies comparing PBA vs PSI for PVS with reported outcomes of restenosis and procedure-related complications in all patient categories. In adults, PVS following atrial fibrillation ablation and in children PVS related to congenital etiology or post-procedural PVS following total or partial anomalous pulmonary venous return repair were included. The patient-centered outcomes were risk of restenosis requiring re-intervention and procedural-related complications. The meta-analysis was performed by computing odds ratios (ORs) using the random effects model based on underlying statistical heterogeneity.
RESULTS Eight observational studies treating 768 severe PVS in 487 patients met our inclusion criteria. The age range of patients was 6 months to 70 years and 67% were males. The primary outcome of the re-stenosis requiring re-intervention occurred in 196 of 325 veins in the PBA group and 111 of 443 veins in the PSI group. Compared to PSI, PBA was associated with a significantly increased risk of re-stenosis (OR 2.91, 95%CI: 1.15-7.37, P = 0.025, I2 = 79.2%). Secondary outcomes of the procedure-related complications occurred in 7 of 122 patients in the PBA group and 6 of 69 in the PSI group. There were no statistically significant differences in the safety outcomes between the two groups (OR: 0.94, 95%CI: 0.23-3.76, P = 0.929), I2 = 0.0%).
CONCLUSION Across all patient categories with PVS, PSI is associated with reduced risk of re-intervention and is as safe as PBA and should be considered first-line therapy for PVS.

[PMID: 37752694 PMCID: PMC10522888 DOI: 10.1002/1348-9585.12426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 08/29/2023] [Accepted: 09/07/2023] [Indexed: 09/28/2023] Open
Abstract
OBJECTIVES Psychosocial working conditions of ready-made garment (RMG) workers have been associated with poorer self-reported health outcomes. However, no such research has been done with respect to physiological markers that are considered to reflect stress. We consequently aimed to investigate associations of psychosocial working conditions with such a marker, that is, hair cortisol, among RMG workers in Bangladesh. METHODS We conducted semi-structured face-to-face interviews in labor colonies in the Mirpur area, Dhaka, Bangladesh, in February and March 2021 with individuals identifying as garment workers. The interview inquired after various workplace stressors and resources (i.e., workplace support, workplace bullying, vertical trust, beneficial leadership, work-family conflict, and financial issues including savings, debts, financial obligations, and financial support). In addition, hair samples of 2 cm length were collected from participants. Hair cortisol concentrations (HCC) were determined based on liquid chromatography-tandem mass spectrometry (LC-MS/MS). Linear regression models were run to detect possible associations of workplace stressors and resources with HCC. RESULTS In total, data of 576 participants were included in the analysis (71.9% female, mean age = 25.9 years). Mean HCC was 4.4 pg/mg (standard deviation = 2.1 pg/mg). The sole variable significantly associated with increased HCC was "having to keep your job to support your children or spouse financially" (β = 0.28 [95% confidence interval 0.02-0.55]). CONCLUSIONS The sole workplace stressor significantly associated with increased HCC was the necessity to keep one's job to support children or spouse financially. This observation can, however, barely be disentangled from the fact that one has children/a spouse.

Abstract
OBJECTIVES This study aims to quantify the degree of work-family conflict (WFC) and financial issues among ready-made garment (RMG) workers in Bangladesh and to investigate their potential associations with self-reported health outcomes. METHODS We conducted a cross-sectional survey among 1118 RMG workers in labor colonies in Dhaka, Bangladesh, in February and March 2021. Descriptive analyses were performed to characterize WFC (i.e., family life disturbing the job or facing problems in family due to the job) and financial issues (i.e., savings, debt, financial obligations, financial support). We ran multivariable Poisson regression models to examine possible associations between WFC and financial issues and workers' health (self-reported general health and 10 specific health complaints). RESULTS We found low levels of WFC, low levels of savings, moderate levels of debt, and high levels of financial obligations: virtually all workers agreed they had to keep their job to financially support their spouse, children or other relatives. Only about a third of workers expected they would be able to receive financial support in case of a job loss. Work-family conflict was positively associated with poor health but not consistently with specific symptoms. Financial support was negatively associated, whereas being indebted was weakly positively associated with poor health. CONCLUSIONS Our findings suggest low levels of WFC among RMG workers but high levels of financial obligations. Work-family conflict was positively associated with poor health, but not consistently with specific symptoms. Being indebted was weakly positively associated with poor health. Future prospective studies are needed to confirm these findings.

Abstract
BACKGROUND Bangladesh is one of the world's largest garment exporters. Physical working conditions of garment workers are precarious and known to largely affect their health. Research on garment workers' psychosocial working conditions, however, is scarce. We aimed to quantify psychosocial working conditions of garment workers and possible associations with workers' health. METHODS We conducted a cross-sectional survey among 1,118 ready-made garment (RMG) workers in labor colonies in Dhaka, Bangladesh, in February 2021. Descriptive analyses were performed to characterize social stressors (e.g., being bullied at work, poor leadership) and social resources at work (e.g., receiving support at work, vertical trust between management and employees, beneficial leadership) and workers' health (self-reported overall health and 10 specific health complaints). To examine links of social stressors and social resources with self-reported health outcomes we ran multivariable Poisson regression models yielding prevalence ratios (PR) and 95% confidence intervals (CI). RESULTS We found low to moderate levels of workplace bullying and high levels of poor leadership (i.e., supervisors not caring about workers' problems). We also found high levels of social support, vertical trust and beneficial leadership (i.e., supervisors taking decisions free of bias). Garment workers frequently suffered from health complaints, first and foremost headache (68.3%), cold (55.3%), and back pain (50.7%). Health outcomes were poorer among workers who reported to be bullied at work versus not bullied (e.g., PR 1.55 [95% CI 1.32-1.92] for poor self-reported health when bullied by colleagues) and health was better among those reporting to feel supported versus unsupported (e.g., PR 0.61 [0.52-0.71] for poor self-reported health when supported by supervisor). Perceived vertical trust between workers and management was weakly associated with better health. Leadership behavior did not display a consistent pattern. CONCLUSIONS Our findings suggest that working conditions of RMG workers are rather good (e.g., characterized by low levels of bullying and high levels of support, vertical trust and beneficial leadership). The majority of workers reported good or very good health, although health complaints were frequently mentioned, first and foremost headache, cold, and back pain. Associations between psychosocial working conditions and health indicate worse working conditions being associated with poorer health.

Abstract
Introduction Elective care in the UK came to a standstill with the advent of the COVID-19 pandemic. A restart could only be enabled with ‘green site’ separation and a ‘covid protected’ zone. A ‘hospital within the hospital’ concept was developed including 9 elective theatres, 28 ring fenced elective beds, a surgical enhanced care unit, a canteen, and a separated entrance. This model was underpinned with PPE, enhanced infection control and guidance for staff. The study documented the ability to recover elective activity and therefore provide a training environment for surgical trainees. Method Data was collected weekly (7/20 to 1/21) through the business informatics system with regard to theatres cases completed compared to the activity achieved in the 11-theatre elective estate pre COVID-19. Results Pre COVID-19, an average of 263 cases were completed per week. In the first week of operation, 31% of theatre capacity was achieved. By week 7, 106% of pre COVID was recorded and 130% by week 11. This was maintained until the impact of the second wave where activity has reduced to 50% but is not anticipated to reduce further as local anaesthetic and blocks maybe utilised. Conclusions This ‘hospital within the hospital’ has enabled elective care to return to above normal levels, with increased efficiencies. This has enabled a rapid return to a training environment for trainees disheartened with deployment to critical care in the first wave.

Abstract
Introduction
Multidisciplinary foot care services contribute to the reduction in amputations from foot ulceration secondary to diabetes. The COVID-19 pandemic pressurised services and required a pause of elective care. This study reports the patient’s experience of foot care provision during the first wave where self-care, virtual appointments and patient directed appointments were utilised.
Method
Diabetic foot patients were retrospectively identified over a one-month period booked for MDT care (in hospital, OPD, diabetic foot clinic, community podiatry clinic or at home). All patients>16 years of age diagnosed with a new or previous diabetic foot ulcer or post-operative foot wound were included. Data was collated via a patient survey form and descriptive statistics were used to characterize the study population and responses.
Results
63 patients were identified (1/10 – 30/10) with data collated from 51 respondents (81%). 78% (40/51) were male. Median age was 69 years (IQR 59–76). 86% were comfortable attending a hospital appointment. 92% reported continuing to receive an appropriate level of care. All of the patients felt well supported and knew how to access the foot care service. 29% utilised virtual care. 82% (42/51) considered face to face appointments were more suitable for follow up rather than virtual/phone appointments.
Conclusions
It was possible to continue to provide safe diabetic foot care despite the COVID-19 pandemic but careful patient selection and communication is the key.

Abstract
BACKGROUND Although direct oral anticoagulants (DOACs) have been shown to be effective at reducing the risk of stroke in patients with atrial fibrillation/flutter (AF), they are sometimes underdosed off-label to mitigate their associated higher bleeding risk. We sought to evaluate frequency and clinical outcomes of inappropriate underdosing of DOACS in patients with AF. METHODS We conducted a study of subjects with AF who had a clinical indication for stroke prophylaxis (with a congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke or transient ischemic attack, vascular disease, age 65 to 47 years, sex category [CHA2DS2-VASc] of 2 or greater) and were prescribed 1 of the 4 clinically approved DOACs (apixaban, rivaroxaban, dabigatran, or edoxaban). We compared all-cause mortality, composite of stroke and systemic embolism, composite of myocardial infarction (MI), acute coronary syndromes (ACS), and coronary revascularization, and major bleeding between patients appropriately dosed and inappropriately underdosed. RESULTS A total of 8125 patients met inclusion criteria, with a mean follow up of 2.2 ± 2 years. Of those, 1724 patients (21.2%) were inappropriately dosed. After adjusting for baseline variables, there was no difference in all-cause mortality, risk of stroke or systemic embolism, International Society on Thrombosis and Haemostasis (ISTH) major bleeding, or composite of myocardial infarction, acute coronary syndromes, or coronary revascularization between patients appropriately dosed and inappropriately underdosed. In subgroup analysis, only apixaban demonstrated an increased incidence all-cause mortality (hazard ratio [HR] 1.24, 95% confidence interval [CI] 1.03-1.49) with inappropriate underdosing. There was no difference in the remaining clinical outcomes noted on subgroup analysis. CONCLUSION Underdosing of DOACs did not minimize risk of bleeding, systemic embolization or all-cause mortality in patients with AF. Inappropriate underdosing with apixaban in particular was associated with increased all-cause mortality.

Abstract
Background Brugada syndrome is an inherited cardiac channelopathy associated with major arrhythmic events (MAEs). The presence of a positive family history of sudden cardiac death (SCD) as a risk predictor of MAE remains controversial. We aimed to examine the association between family history of SCD and MAEs stratified by age of SCD with a systematic review and meta-analysis. Methods and Results We searched the databases of MEDLINE and EMBASE from January 1992 to January 2020. Data from each study were combined using the random-effects model. Fitted metaregression was performed to evaluate the association between the age of SCD in families and the risk of MAE. Twenty-two studies from 2004 to 2019 were included in this meta-analysis involving 3386 patients with Brugada syndrome. The overall family history of SCD was not associated with increased risk of MAE in Brugada syndrome (pooled odds ratio [OR], 1.11; 95% CI, 0.82-1.51; P=0.489, I2=45.0%). However, a history of SCD in family members of age younger than 40 years of age did increase the risk of MAE by ≈2-fold (pooled OR, 2.03; 95% CI, 1.11-3.73; P=0.022, I2=0.0%). When stratified by the age of cut point at 50, 45, 40, and 35 years old, a history of SCD in younger family member was significantly associated with a higher risk of MAE (pooled OR, 0.49, 1.30, 1.51, and 2.97, respectively; P=0.046). Conclusions A history of SCD among family members of age younger than 40 years was associated with a higher risk of MAE.

Abstract
Abstract
Introduction
Adverse surgical events remain at an unacceptably high level despite multiple global safety initiatives being introduced. As yet, however there is no conclusive evidence to identify whether physiological markers can be used to predict whether a surgeon will make an error
Method
Surgeons were asked to complete a simulated laparoscopic cholecystectomy task while physiological metrics and gaze behaviour was tracked. LightGBM and CatBoost were used to predict the physiological metric most useful in predicting whether a surgeon was about to make an error. The binary task used a boolean value of “does an error occur in the next 5 seconds” as the dependent variable, while the multiclass task classified the severity of error (0, 1, 2, 3).
Results
Autocorrelation with lag (eventually calculated with a lag of timestep 2) measured the tendency of this timeseries to correlate with itself. The degree of correlation, or lack of correlation, and sudden changes in correlation over time were gleaned from this feature.
Conclusions
Skin conductance was most likely to successfully predict impending error. However when gaze features were added, overall model performance improved by 6.4%. The potential for reduction in surgical error rate and improvement in patient safety are important factors to consider.

Abstract
Herbal medicines are becoming more popular and acceptable day by day due to their effectiveness, limited side effects, and cost-effectiveness. Cholistani plants are reported as a rich source of antibacterial, antifungal, antiprotozoal, antioxidant, and anticancer agents. The current study has evaluated antiviral potential of selected Cholistani plants. The whole plants were collected, ground and used in extract formation with n-hexane, ethyl acetate and n-butanol. All the extracts were concentrated by using a rotary evaporator and concentrate was finally dissolved in an appropriate vol of the same solvent. All of the extracts were tested for their antiviral potential by using 9-11 days old chick embryonated eggs. Each extract was tested against the Avian Influenza virus H9N2 strain (AIV), New Castle Disease virus Lasoota strain (NDV), Infectious bronchitis virus (IBV) and an Infectious bursal disease virus (IBDV). Hemagglutination test (HA) and Indirect Hemagglutination (IHA) tests were performed for different viruses. The overall order of the antiviral potential of Cholistani plants against viruses was NDV>IBV>IBDV>AIV. In terms of antiviral activity from extracts, the order of activity was n-butanol>ethyl acetate>n-hexane. The medicinal plants Achyranthes aspera, Neuroda procumbens, Panicum antidotale, Ochthochloa compressa and Suaeda fruticose were very effective against all four poultry viruses through their extracts. The low IC50 values of these extracts confirm the high antiviral potential against these viruses. It is worth to mention that Achyranthes aspera was found positive against IBDV through all its extracts which overcome the problem of unavailability of any known drug against IBDV. In short, the study proved that Cholistani plants are rich source of antiviral agent and their extracts can be used as good source of antiviral drugs both in crude and in purified form.

Abstract
INTRODUCTION The right ventricle (RV) strain measured by speckle tracking (RVS) is an echocardiographic parameter used to assess RV function. We compared RVS to RV fractional area change (FAC%), tricuspid annular plane systolic excursion (TAPSE) and Doppler tissue imaging-derived peak systolic velocity (S') in the assessment of right ventricular (RV) systolic function measured using cardiac magnetic resonance imaging (MRI). METHODS We enrolled consecutive patients who underwent cardiac MRI between Jan 2012 and Dec 2017 and a transthoracic echocardiogram (TTE) within 1 month of the MRI with no interval event. Baseline clinical characteristics and MRI parameters were extracted from chart review. Echocardiographic parameters were measured prospectively. TTE parameters including RVS, TAPSE, S', and FAC% were tested for accuracy to identify impaired RV EF (EF < 45% & <30%) using receiver operator curves. RESULTS The study cohort included 500 patients with mean age 55 years ± 18 and peak tricuspid regurgitation velocity 2.7 ± 1.4 m/s. The area under ROC for RVS was 0.69 (95% CI 0.63-0.75) and 0.78 (95% CI 0.70-0.88) to predict RVEF < 45% & RVEF < 30%, respectively. The RV FAC% had second highest accuracy of predicting RVEF among all the TTE parameters tested in study. CONCLUSION Right ventricular strain is the most accurate echocardiographic method to detect impaired right ventricular systolic function when using MRI as the gold standard.

Abstract
Pericardial disease is a recognized manifestation of cardiovascular disease in the end-stage renal disease (ESRD) population, and can manifest as pericardial effusion, though the prognosis of pericardial disease in ESRD patients is unclear. In the modern era of renal replacement therapy, little is known about the prevalence and the implications of pericardial effusion in ESRD patients, its echocardiographic characteristics, and risk factors. We conducted a retrospective chart review on subjects > than 18 years of age with known ESRD who were undergoing outpatient evaluation for renal transplantation at Mayo Clinic Arizona between January 2001 and December 2015 and had baseline echocardiogram completed within 3 months of their initial evaluation. Patients with moderate sized pericardial effusions or larger were identified. The pericardial effusion cohort was age and gender matched with a cohort of patients with ESRD without pericardial effusion in a 1:2 fashion. 54 patients with moderate or greater sized pericardial effusion out of 2,820 patients that fit our inclusion criteria, corresponding to a prevalence of 1.9%. A total of 41 patients or 75.9%, had a moderate sized effusion. A total of 13 patients, or 24.1% had a large sized effusion, 7 of whom had tamponade physiology on echocardiography. The presence and size of the effusion was not predictive for worse outcomes. Hemodialysis duration was protective, but no other factors were predictive or protective in the development of moderate sized or larger pericardial effusions, including echocardiographic parameters.

Abstract
BACKGROUND Transcatheter aortic valve replacement (TAVR) is a reliable method of treating patients with severe aortic stenosis, but is associated with postprocedure conduction defects. OBJECTIVE The purpose of this study was to compare clinical outcomes in patients who developed advanced conduction defects post-TAVR to those who did not. METHODS We conducted a retrospective chart review of 243 patients who underwent balloon-expandable TAVR with the Edwards Sapien valve to determine the incidence of advanced conduction defects in our cohort. We compared clinical outcomes including overall mortality, improvement in symptomatology, and improvement in left ventricular ejection fraction. RESULTS Among the 243 patients included in the study, 9.1% (22/243) required permanent pacemaker (PPM); 19.8% (48/243) developed left bundle branch block (LBBB), and 71.2% (173/243) did not develop any permanent advanced conduction defects. Overall 1-year mortality was similar across all three groups. There was significant improvement in New York Heart Association functional capacity of all groups post-TAVR, but this was much less in the PPM group (45.5% vs 68.8%, P = .04). Postprocedure from TAVR, patients with LBBB or PM were less likely to have improvement in their ejection fraction (net loss of -0.7% for LBBB and -5.7% for PPM compared to a net gain of 2.3% for no-LBBB/PM (P = .02). CONCLUSION Patients who develop LBBB or require PM post-TAVR with Edwards Sapien valves are less likely to improve New York Heart Association functional capacity and more likely to have no improvement or deterioration of their pre-TAVR left ventricular ejection fraction.

Abstract
AIM This study evaluated the effectiveness and safety of rapid and slow rehydration in children aged 6-60 months with dehydrating diarrhoea and severe malnutrition. METHODS A randomised controlled trial was conducted from July 2011 to March 2014 at the International Centre for Diarrhoeal Disease Research Bangladesh. We included children with weight for age and, or, weight for length Z-scores of less than -3 or with bipedal oedema and acute diarrhoea with severe dehydration. The children received intravenous fluid at different rates: 105 rapidly over six hours and 103 slowly over the 12 hours recommended by the World Health Organization. RESULTS All the children were successfully rehydrated. The admittance weights were similar for the slow and rapid groups: 8.4 kg and 8.3 kg. After 24 hours, the mean percentage weight gain was 8.5% and 9.0%, respectively. This confirmed that most of the children had been suffering from severe dehydration on admission. The respective proportions of children who received unscheduled intravenous fluid were 18% and 17%. None developed fluid overload or heart failure and most recovered normal renal function after rehydration. CONCLUSION Rapid rehydration saved time, was as safe as slow rehydration and was a better option for dehydrating diarrhoea and severe malnutrition.

Abstract
Abstract
Background
Coronary artery disease (CAD) and atrial fibrillation (AF) are commonly associated. Co-treatment with multiple anti-thrombotic agents can increase the risk of bleeding.
Purpose
We sought to evaluate patient-centered outcomes in patients with AF on double therapy with direct oral anticoagulants (DOACs) compared to patients with standard triple therapy, [a vitamin K antagonist (VKA) plus dual antiplatelet therapy].
Methods
We performed an extensive systematic review of the literature and meta-analysis of randomized controlled trials reporting outcomes of patients receiving double therapy with DOACs compared to triple therapy with VKAs in patients with AF undergoing percutaneous coronary intervention (PCI). Patient-centered outcomes were the International Society of Thrombosis and Hemostasis (ISTH) major or clinically relevant non-major bleeding (CRNB), all-cause mortality, major adverse cardiovascular events (MACE), myocardial infarction, stent thrombosis, and stroke.
Results
Four randomized controlled trials (9602 patients) met our inclusion criteria. Compared to VKAs, DOACs were associated with significantly lower ISTH major bleeding/ CRNB (RR - 0.75, 95% CI: 0.67-0.82, p < 0.00001, I2 = 11%). There were no statistically significant differences in the efficacy outcomes, including myocardial infarction (RR- 0.99, 95% CI :0.79-1.25, p = 0.96, I2 = 0%), stent thrombosis (RR - 0.97, 95% CI: 0.6-1.55, p = 0.89, I2 = 0%), ischemic stroke (RR - 0.76, 95% CI: 0.5-1.15, p = 0.19, I2 = 0%), all-cause mortality (RR - 1.06, 95% CI: 0.85-1.31, p = 0.61, I2 = 0%) and MACE (RR - 1.06, 95% CI: 0.91-1.22, p = 0.97, I2 = 0%).
Conclusion
Compared with triple therapy with VKAS, double therapy with DOACs is associated with a reduced risk of bleeding and is as effective in patients with AF undergoing PCI.
