A post hoc comparative real-world analysis of HEAD-US score for joint health assessment of patients with severe haemophilia A and B in Spain.

AIM: Joint damage due to haemarthrosis can be effectively monitored with point-of care ultrasound using the Haemophilia Early Arthropathy Detection with US (HEAD-US) scoring system. A post hoc comparative analysis of the joint status of patients with severe haemophilia A (HA) or B (HB) was performed. METHODS: The databases of two observational, cross-sectional studies that recruited patients with HA or HB from 12 Spanish centres were analysed to compare the status of the elbows, knees and ankles in patients with severe disease according to treatment modality. The HEAD-US score was calculated in both studies by the same trained operators. RESULTS: Overall, 95 HA and 41 HB severe patients were included, with a mean age of 35.2 ± 11.8 and 32.7 ± 14.2 years, respectively. The percentage of patients who received prophylaxis, over on-demand (OD) treatment, was much higher in HA (91.6%) than in HB (65.8%) patients. With a similar number of target joints, the HEAD-US score was zero in 6.3% HA and 22.0% HB patients (p < .01), respectively. The HA population showed significantly worse HEAD-US scores. Whilst osteochondral damage occurred more frequently in patients OD or tertiary prophylaxis, our data suggest that articular damage is less prominent in primary/secondary prophylaxis, regardless of the type of haemophilia. These latter treatment modalities were also associated with a lower prevalence of synovial hypertrophy, particularly in HB patients. CONCLUSION: This post hoc analysis indicates that joint status seems to be significantly influenced by haemophilia type (HA or HB) and treatment modality in these severe Spanish populations with severe disease. Continuing HEAD-US monitoring for the early detection and management of intra-articular abnormalities, as well as more efficiently tailored therapies should be warranted.

Applicability of the European Society of Cardiology Guidelines on the management of acute coronary syndromes to older people with haemophilia A - A modified Delphi consensus by the ADVANCE Working Group.

INTRODUCTION: As people with haemophilia (PWH) receive better treatment and live longer they are more likely to encounter cardiovascular disease (CVD) and other comorbidities. ESC guidelines for the acute management of patients presenting with acute coronary syndrome (ACS) are based on the non-haemophilia population. AIM: To review the guidelines and propose relevant adaptations for PWHA without inhibitors who are treated with prophylaxis and present with ACS. METHODS: As part of the ADVANCE Group, 20 European haemophilia experts used a modified Delphi approach to develop and gain consensus on proposed adaptations of the ESC guidelines for PWHA without inhibitors. RESULTS: Of the 32 Class I recommendations across both guidelines, adaptions were considered necessary and proposed for 15. The adaptions highlight the need to provide sufficient FVIII trough levels at the time of antithrombotic treatment in people with haemophilia A (HA) without inhibitors. Patients receiving emicizumab prophylaxis and requiring oral anticoagulation therapy or combined single antiplatelet plus oral anticoagulation therapy will require additional FVIII replacement therapy. CONCLUSION: In the absence of high-quality clinical evidence, the combined expert opinion used to develop these adaptions to the current ESC guidelines may help to guide clinicians in their treatment decisions when a PWHA presents with ACS.

Longitudinal perturbations of plasma nuclear magnetic resonance profiles in neonatal encephalopathy.

BACKGROUND: Neonatal encephalopathy (NE) is a major cause of mortality and severe neurological disability in the neonatal period and beyond. We hypothesized that the degree of brain injury is reflected in the molecular composition of peripheral blood samples. METHODS: A sub-cohort of 28 newborns included in the HYPOTOP trial was studied. Brain injury was assessed by magnetic resonance imaging (MRI) once per patient and neurodevelopment at 24 months of age was evaluated using the Bayley III Scales of Infant and Toddler Development. The nuclear magnetic resonance (NMR) profile of 60 plasma samples collected before, during, and after cooling was recorded. RESULTS: In total, 249 molecular features were quantitated in plasma samples from newborns and postnatal age showed to affect detected NMR profiles. Lactate, beta-hydroxybutyrate, pyruvate, and three triglyceride biomarkers showed the ability to discern between different degrees of brain injury according to MRI scores. The prediction performance of lactate was superior as compared to other clinical and biochemical parameters. CONCLUSIONS: This is the first longitudinal study of an ample compound panel recorded by NMR spectroscopy in plasma from NE infants. The serial determination of lactate confirms its solid position as reliable candidate biomarker for predicting the severity of brain injury. IMPACT: The use of nuclear magnetic resonance (NMR) spectroscopy enables the simultaneous quantitation of 249 compounds in a small volume (i.e., 100 µL) of plasma. Longitudinal perturbations of plasma NMR profiles were linked to magnetic resonance imaging (MRI) outcomes of infants with neonatal encephalopathy (NE). Lactate, beta-hydroxybutyrate, pyruvate, and three triglyceride biomarkers showed the ability to discern between different degrees of brain injury according to MRI scores. Lactate is a minimally invasive candidate biomarker for early staging of MRI brain injury in NE infants that might be readily implemented in clinical guidelines for NE outcome prediction.

Resuscitators' opinions on using a respiratory function monitor during neonatal resuscitation.

AIM: The aim of this study was to assess the resuscitators' opinions of the usefulness and clinical value of using a respiratory function monitor (RFM) when resuscitating extremely preterm infants with positive pressure ventilation. METHODS: The link to an online survey was sent to 106 resuscitators from six countries who were involved in a multicentre trial that compared the percentage of inflations within a predefined target range with and without the RFM. The resuscitators were asked to assess the usefulness and clinical value of the RFM. The survey was online for 4 months after the trial ended in May 2019. RESULTS: The survey was completed by 74 (70%) resuscitators of which 99% considered the RFM to be helpful during neonatal resuscitation and 92% indicated that it influenced their decision-making. The majority (76%) indicated that using the RFM improved their practice and made resuscitation more effective, even when the RFM was not available. Inadequate training was the key issue that limited the effectiveness of the RFM: 45% felt insufficiently trained, and 78% felt more training in using and interpreting the RFM would have been beneficial. CONCLUSION: Resuscitators considered the RFM to be helpful to guide neonatal resuscitation, but sufficient training was required to achieve the maximum benefit.

Prediction of clinical events by liver stiffness and chronic kidney disease by NAFLD in patients with type-2 diabetes.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with poorer glycemic control and a higher risk of type-2 diabetes (T2D) complications, extrahepatic and cardiovascular disease (CVD). Our study aim was to evaluate the association between NAFLD, T2D complications, and the development of overall clinical events (OCE) (CV, liver-related, and mortality) in patients with T2D. METHODS: Prospective single-center study comprising T2D subjects with no history of CVD and non-T2D matched controls. Patients were selected from the Outpatient Diabetes Clinic of Vall d'Hebron Hospital and related primary care centers. RESULTS: 186 diabetics and 57 controls were included. Amongst T2D, 124/186 subjects had NAFLD (66.6%). T2D-NAFLD subjects showed a heavier metabolic burden and higher median liver stiffness (5.6kPa [4.5-7.3] vs 4.8 [4.2-5.8]; p=0.004) compared to non-NAFLD diabetics. During a median follow-up of 5.6 years, 33 (17.7%) T2D patients developed OCE vs 4 (7.0%) controls (p=0.049). No differences were found for OCE between NAFLD and non-NAFLD diabetics (16.9% vs 19.4%; p=0.68). CV was the most reported outcome and only one liver event occurred. NAFLD diabetics showed more often chronic kidney disease (CKD), whereas T2D complications and subclinical CVD rates were similar. A higher liver stiffness, older age, and male gender were independently associated with OCE amongst the entire T2D population and NAFLD diabetics. CONCLUSIONS: NAFLD and liver stiffness were associated with CKD and clinical outcomes in diabetics, respectively. A hepatic evaluation is recommended to identify high-risk T2D patients that would benefit from early referral to specialized care.

Noninvasive monitoring of evolving urinary metabolic patterns in neonatal encephalopathy.

BACKGROUND: Infants with moderate and severe neonatal encephalopathy (NE) frequently suffer from long-term adverse outcomes. We hypothesize that the urinary metabolome of newborns with NE reflects the evolution of injury patterns observed with magnetic resonance imaging (MRI). METHODS: Eligible patients were newborn infants with perinatal asphyxia evolving to NE and qualifying for therapeutic hypothermia (TH) included in the HYPOTOP trial. MRI was employed for characterizing brain injury. Urine samples of 55 infants were collected before, during, and after TH. Metabolic profiles of samples were recorded employing three complementary mass spectrometry-based assays, and the alteration of detected metabolic features between groups was assessed. RESULTS: The longitudinal assessment revealed significant perturbations of the urinary metabolome. After 24 h of TH, a stable disease pattern evolved characterized by the alterations of 4-8% of metabolic features related to lipid metabolism, metabolism of cofactors and vitamins, glycan biosynthesis and metabolism, amino acid metabolism, and nucleotide metabolism. Characteristic metabolomic fingerprints were observed for different MRI injury patterns. CONCLUSIONS: This study shows the potential of urinary metabolic profiles for the noninvasive monitoring of brain injury of infants with NE during TH. IMPACT: A comprehensive approach for the study of the urinary metabolome was employed involving a semi-targeted capillary electrophoresis-time-of-flight mass spectrometry (TOFMS) assay, an untargeted ultra-performance liquid chromatography (UPLC)-quadrupole TOFMS assay, and a targeted UPLC-tandem MS-based method for the quantification of amino acids. The longitudinal study of the urinary metabolome identified dynamic metabolic changes between birth and until 96 h after the initiation of TH. The identification of altered metabolic pathways in newborns with pathologic MRI outcomes might offer the possibility of developing noninvasive monitoring approaches for personalized adjustment of the treatment and for supporting early outcome prediction.

Activated prothrombin complex concentrate to treat bleeding events in acquired hemophilia A: BAHAS study.

OBJECTIVE: Activated prothrombin complex concentrate (aPCC) is a bypassing agent indicated to treat bleeds in patients with acquired hemophilia A (AHA). Nevertheless, its efficacy and safety in the real-world setting have not often been addressed. METHODS: We report the experience of Spanish reference centers for coagulation disorders and from acquired hemophilia Spanish Registry (AHASR) from August 2012 to February 2021. Follow-up period of 30 days after aPCC withdrawal. RESULTS: Thirty patients with a median age of 70 years old, suffering from 51 bleeds treated with aPCC were finally evaluated. As first-line treatment, aPCC stopped bleeding in 13 of 14 (92.9%) cases. aPCC as the second line after recombinant factor VIIa failure, stopped bleeding in all cases. In 17 patients, aPCC was used far from initial bleed control as prophylaxis of rebleeding with 94% effectiveness. No thromboembolic episodes were communicated. One patient developed hypofibrinogenemia, which did not prevent aPCC from halting bleeding. No other serious adverse events possibly or probably associated with aPCC were reported. CONCLUSIONS: This data support aPCC as hemostatic treatment in AHA with high effectiveness and excellent safety profile in acute bleeds and as extended use to prevent rebleedings, even in aging people with high cardiovascular risk.

Health-related quality of life and health status in adolescent and adult people with haemophilia A without factor VIII inhibitors-A non-interventional study.

INTRODUCTION: Real-world data on health-related outcomes in persons with haemophilia A (PwHA) can provide useful information for improving patient care. The global, non-interventional study (NIS; NCT02476942) prospectively collected high-quality data in PwHA, including those without factor VIII (FVIII) inhibitors treated according to local routine clinical practice. AIM: To report health-related quality of life (HRQoL) and health status of adult/adolescent PwHA without FVIII inhibitors. METHODS: Participants were PwHA without FVIII inhibitors age ≥12 years; they remained on existing episodic treatment or prophylaxis. HRQoL was assessed by Haemophilia Quality of Life Questionnaire for Adults (Haem-A-QoL) or Haemophilia-Specific Quality of Life Assessment for Children and Adolescents Short Form (Haemo-QoL-SF II). Health status was assessed through EuroQol 5-Dimensions 5-Levels (EQ-5D-5L) index utility score and visual analogue scale (EQ-VAS). RESULTS: Ninety-four participants enrolled; median age was 34.0 years (range 12-76). Forty-five received episodic treatment and 49 received prophylaxis for a median time of 27.7 weeks and 30.4 weeks, respectively. Mean (standard deviation) baseline Haem-A-QoL total scores were 40.1 (17.0) for the episodic group and 26.6 (14.6) for the prophylaxis group, indicating impairments in HRQoL, which remained consistent over time. Mean EQ-5D-5L IUS scores were similar between treatment regimens (0.8 episodic; 0.9 prophylaxis) and consistent over time. The mean EQ-VAS scores were similar between treatment regimens, and lower on days when bleeding occurred (79.0 vs 85.0 for episodic treatment; 77.0 vs 82.0 for prophylaxis, respectively). CONCLUSIONS: Adult and adolescent PwHA without FVIII inhibitors had HRQoL impairments regardless of whether they were treated with episodic or prophylactic standard care with FVIII.

Ultrasound evaluation of joint damage and disease activity in adult patients with severe haemophilia A using the HEAD-US system.

INTRODUCTION: The Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) system and scoring scale has proven to be an accurate and time-efficient imaging method for identifying joint damage in patients with haemophilia. AIM: Observational, multicentre, cross-sectional study conducted in 8 centres in Spain that assessed the joint status of adult patients with severe haemophilia A (SHA) using HEAD-US. METHODS: Joint status of the elbow, knee and ankle was evaluated in adults with SHA receiving on-demand (OD) treatment, or primary (PP), secondary (SP), tertiary (TP) or intermittent (IP) prophylaxis. RESULTS: Of the 95 patients enrolled, 87 received prophylaxis (6.3% PP, 38.9% SP, 43.2% TP and 3.2% IP). Mean age was 35.2 years, and 59% of patients had not undergone image testing in the last year. The HEAD-US score was 0 in all joints in 6.3% of patients. The ankle was the most affected joint, regardless of treatment regimen. Patients receiving OD treatment, TP or IP had the overall worst scores, mainly in the ankles and elbows; a similar but milder profile was observed in patients on SP; and patients on PP had the best score in all joints. CONCLUSION: Joint function may be effectively preserved in patients with SHA on PP, but OD treatment or later initiation of prophylaxis does not seem to prevent progression of arthropathy. Disease worsening was observed in patients OD, TP or IP, most often affecting ankles and elbows. Closer ultrasound imaging monitoring may improve management of these patients.

Effects of very early start of norepinephrine in patients with septic shock: a propensity score-based analysis.

BACKGROUND: Optimal timing for the start of vasopressors (VP) in septic shock has not been widely studied since it is assumed that fluids must be administered in advance. We sought to evaluate whether a very early start of VP, even without completing the initial fluid loading, might impact clinical outcomes in septic shock. METHODS: A total of 337 patients with sepsis requiring VP support for at least 6 h were initially selected from a prospectively collected database in a 90-bed mixed-ICU during a 24-month period. They were classified into very-early (VE-VPs) or delayed vasopressor start (D-VPs) categories according to whether norepinephrine was initiated or not within/before the next hour of the first resuscitative fluid load. Then, VE-VPs (n = 93) patients were 1:1 propensity matched to D-VPs (n = 93) based on age; source of admission (emergency room, general wards, intensive care unit); chronic and acute comorbidities; and lactate, heart rate, systolic, and diastolic pressure at vasopressor start. A risk-adjusted Cox proportional hazard model was fitted to assess the association between VE-VPs and day 28 mortality. Finally, a sensitivity analysis was performed also including those patients requiring VP support for less than 6 h. RESULTS: Patients subjected to VE-VPs received significantly less resuscitation fluids at vasopressor starting (0[0-510] vs. 1500[650-2300] mL, p < 0.001) and during the first 8 h of resuscitation (1100[500-1900] vs. 2600[1600-3800] mL, p < 0.001), with no significant increase in acute renal failure and/or renal replacement therapy requirements. VE-VPs was related with significant lower net fluid balances 8 and 24 h after VPs. VE-VPs was also associated with a significant reduction in the risk of death compared to D-VPs (HR 0.31, CI95% 0.17-0.57, p < 0.001) at day 28. Such association was maintained after including patients receiving vasopressors for < 6 h. CONCLUSION: A very early start of vasopressor support seems to be safe, might limit the amount of fluids to resuscitate septic shock, and could lead to better clinical outcomes.

The Role of Ultrasound for Detecting Occult Penetrating Cardiac Wounds in Hemodynamically Stable Patients.

BACKGROUND: There is evidence in favor of using the ultrasound as the primary screening tool in looking for an occult cardiac injury. We report on a prospective single-center study to determine the diagnostic accuracy of chest ultrasound for the diagnosis of occult penetrating cardiac wounds in a low-resource hospital from a middle-income country. METHODS: Data were collected prospectively. We included all consecutive patients 14 years and older who presented to the Emergency Trauma Unit with (1) penetrating injuries to the precordial area and (2) a systolic blood pressure ≥ 90 mmHg (hemodynamically stable). The main outcome measures were sensitivity, specificity, and positive and negative predictive values of ultrasound compared with those of the pericardial window, which was the standard test. RESULTS: A total of 141 patients met the inclusion criteria. Our results showed that for diagnosing an occult cardiac injury, the sensitivity of the chest ultrasonography was 79.31%, and the specificity was 92.86%. Of the 110 patients with a normal or negative ultrasound, six had a positive pericardial window. All of these patients had left hemothoraces. None of them required further cardiac surgical interventions. CONCLUSION: We found that ultrasound was 79% sensitive and 92% specific for the diagnosis of occult penetrating cardiac wounds. However, it should be used with caution in patients with injuries to the cardiac zone and simultaneous left hemothorax.

Joint status in Spanish haemophilia B patients assessed using the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) score.

AIM: The use of musculoskeletal ultrasound (MSK-US) following protocols for haemophilic arthropathy and the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) score can help standardize monitoring in haemophilia. This study evaluated the joint status (elbows, knees and ankles) of patients with haemophilia B (HB) in Spain using MSK-US and the HEAD-US score. METHODS: Haemophilia B patients ≥14 years old were included in this observational, multicentre, cross-sectional study, regardless of their clinical condition, HB severity and treatment received. Two blinded observers were involved in image acquisition and scoring in each centre. RESULTS: Eighty-two patients from 12 centres were enrolled: 27% mild HB, 23% moderate, 50% severe HB. Mean age was 38.9 ± 16.4 years, 60% were treated on demand (OD) and 40% were on prophylaxis. HEAD-US was zero in all joints in 28.6% OD patients and 36.4% on prophylaxis. Mean scores significantly worsened with HB severity, except for the left knee. Patients on primary and secondary prophylaxis had significantly better joint health vs OD patients in all joints, except the right ankle. Among OD patients, those with severe disease presented significantly worse scores in all HEAD-US items related to permanent damage. CONCLUSION: Joint status of HB patients in Spain is influenced by severity and treatment modality, related to the development of arthropathy, which appears prevalent in OD patients with severe HB. Routine assessment with an imaging tool such as ultrasound and HEAD-US system may help to improve joint health by personalizing and adjusting treatment in this population.

Association of Medicaid Expansion Policy with Outcomes in Homeless Patients Requiring Emergency General Surgery.

BACKGROUND: Medicaid expansion has reduced obstacles faced in receiving care. Emergency general surgery (EGS) is a clinical event where delays in appropriate care impact outcomes. Therefore, we assessed the association between non-Medicaid expansion policy and multiple outcomes in homeless patients requiring EGS. METHODS: We used 2014 State Inpatient Database to identify homeless individuals admitted with a primary EGS diagnosis who underwent an EGS procedure. States were divided into those that did and did not implement Medicaid expansion. Multivariable quantile regression was used to examine associations between non-Medicaid expansion states and (1) length of stay and (2) total index hospital charges within the homeless population. Multivariable logistic regression was used to assess the associations between non-Medicaid expansion and (1) mortality, (2) surgical complications, (3) discharge against medical advice, and (4) home healthcare. RESULTS: A total of 6930 homeless patients were identified. Of these, 435 (6.2%) were in non-expansion states. Non-Medicaid expansion was associated with higher charges (coef: $46,264, 95% CI 40,388-52,139). There were non-significant differences in mortality (OR 1.4, 95% CI 0.79-2.62; p = 0.2) or surgical complications (OR 1.16, 95% CI 0.7-1.8; p = 0.4). However, homeless individuals living in non-expansion states did have higher odds of being discharged against medical advice (OR 2.1, 95% CI 1.08-4.05; p = 0.02), and lower odds of receiving home healthcare (OR 0.6, 95% CI 0.4-0.8; p = 0.01). CONCLUSION: Homeless patients living in Medicaid expansion states had lower odds of being discharged against medical advice, higher likelihood of receiving home healthcare and overall lower total index hospital charges.

The Oxygen Load Supplied during Delivery Room Stabilization of Preterm Infants Modifies the DNA Methylation Profile.

OBJECTIVES: To determine whether the amount of oxygen provided during postnatal stabilization changes the DNA methylome in preterm infants. STUDY DESIGN: This prospective, observational study included 32 preterm infants ≤32 weeks of gestation who received oxygen in the delivery room. Patients were monitored using a respiratory function monitor to determine the amount of oxygen received upon stabilization. Blood samples were processed for comparison of DNA methylation before and after resuscitation using a DNA methylation high-resolution microarray Infinium Human DNA methylation EPIC 850K BeadChip. RESULTS: The median amount oxygen provided to preterm infants during stabilization was 644 mLO2/kg. Male sex and vaginal delivery were associated with increased oxygen needs. There were 2626 differentially methylated CpGs representing 1567 genes that showed an association with oxygen load selected and, of these, 85% were hypomethylated. We found that oxygen loads of >500 mLO2/kg changed the methylation pattern of the selected CpGs. Genes associated with these CpGs were "enriched" in KEGG pathways involved in cell cycle progression, DNA repair, and oxidative stress. CONCLUSIONS: The oxygen load provided upon resuscitation modified the DNA methylome. Differential methylation may lead to altered expression of genes related to cell cycle progression, oxidative stress, and DNA repair. The reversibility of these early epigenetic changes is unknown but merits further study.

Oxygen needs during resuscitation and surfactant to achieve stabilisation were independent risks factors for pulmonary interstitial emphysema in preterm infants.

AIM: Pulmonary interstitial emphysema is a severe complication of mechanical ventilation in preterm infants that leads to air leakage and, or, chronic lung disease. We determined the associated risk factors. METHODS: This was a retrospective case-control study from 2005 to 2014 at a regional referral centre in Valencia, Spain. The cases were 54 preterm infants up to 30 weeks' gestation and, or, born weighing less than 1500 g, who were diagnosed with pulmonary interstitial emphysema (PIE). The 54 controls were preterm infants without PIE matched by gestational age. Univariate analysis and multivariate analysis were performed to assess the independent predicting factors. RESULTS: Infants with PIE had been resuscitated with higher mean fractional inspired oxygen concentration (FiO2 ) (p = 0.008), had received higher peak mean positive end expiratory pressure (p = 0.00) and higher mean airway pressure (p = 0.026) 24 hours before diagnosis. PIE patients also received more surfactant (p = 0.00) and had higher mortality (p = 0.034). A Cox regression model identified that independent risk factors were the total amount of surfactant administered and the mean FiO2 during the 24 hours before diagnosis. CONCLUSION: Independent risk factors for pulmonary interstitial emphysema in preterm infants were higher oxygen during resuscitation and a higher need for surfactant and ventilatory pressures before diagnosis.

Presence of acute and chronic renal failure in patients with paroxysmal nocturnal hemoglobinuria: results of a retrospective analysis from the Spanish PNH Registry.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, life-threatening blood disease. With the advent of eculizumab treatment, renal function has substantially improved, although no data from real-world clinical practice are available. An observational, retrospective, multicenter study was conducted in Spain on clinical data obtained from outpatient visits of patients with PNH (Spanish PNH Registry) who had experienced acute (ARF) or chronic (CRF) renal failure. Of the 128 patients registered (April 2014), 60 were diagnosed with classic PNH. Twenty-seven (45.0%) patients with a mean age of 48.5 (±16.2) years had renal failure, ARF or CRF, and were included in this study. Near half of the patients (n = 13; 48.1%) presented with ARF alone, 33.3% (n = 9) had CRF with episodes of ARF, while 18.5% (n = 5) were diagnosed with CRF alone. For patients with diagnosis of PNH and renal failure (n = 27), the median time to the first ARF episode was 6.5 (CI 95%; 2.2, 14.9) years, whereas the median to the diagnosis of CRF was 14.5 (CI 95%; 3.8, 19.2) years after the diagnosis of PNH. Patients with ARF (n = 22) were treated with eculizumab and did not experience new episodes of ARF, except for one patient with sepsis. Of the patients with CRF, two received treatment without experiencing further episodes of ARF. Sixteen patients who completed treatment (11 with ARF and 5 with ARF + CRF) recovered from the episode of ARF or from CRF. Of the remaining patients treated with eculizumab, one patient improved from stages III to II, three patients stabilized without showing disease progression, and one patient progressed from stages III to IV. Treatment with eculizumab in PNH patients has beneficial effects on renal function, preventing ARF and progression to CRF.

[Perinatal Dengue: A case Report]. / Dengue perinatal: Reporte de caso.

INTRODUCTION: Few reports are available about perinatal dengue, with controversial results in regards the risk of perinatal outcome. OBJECTIVE: To report a case of perinatal dengue as a differential diagno sis with neonatal sepsis, which must be considered in endemic areas. CLINICAL CASE: Male newborn of a 23 year-old female, who presented a Non-Structural Protein 1 (NS1) antigen positive to dengue at 36 weeks of gestation and negative anti-dengue antibodies. At day six of the illness a healthy newborn was born. On the second day of life the neonate presented fever with no other pathological findings on the physical exam, associated with severe thrombocytopenia (17,900 platelets/uL), increased C-reactive protein, a positive NS1 antigen, and positive anti-dengue immunoglobulin G (IgG). He was treated with ampicillin and gentamicin according the Institution protocol of neonatal sepsis. The newborn showed clinical improvement, with hemodynamic stability and significant increase of platelets, receiving the medical discharge. CONCLUSIONS: Dengue in pregnancy produces the risk of adverse perinatal outcomes, particularly low birth weight and preterm delivery. Children of mothers diagnosed with dengue at the end of pregnancy should be observed closely with serial hemograms during child's first days of life, due to the high risk of vertical transmission.

Patients with type 1 Gaucher disease in Spain: A cross-sectional evaluation of health status.

A multicentre, cross-sectional epidemiological survey was conducted to describe the health status of patients with type 1 Gaucher disease (GD1) in Spain. Patient data were collected retrospectively from clinical records. Therapeutic goals for seven clinical parameters were chosen as primary outcome measures. 108 GD1 patients (mean age 44.8 years; 53% male) were recruited from 28 hospitals. Ninety-five patients (88%) were receiving treatment for GD1. Hemoglobin concentration was the therapeutic goal with the highest level of achievement, being met by 105 of 108 patients (97%), followed by the goals for liver volume (86/98 patients; 88%), spleen volume (67/77 patients; 87%) and platelet count (81/108 patients; 75%). The goal for bone mineral density (BMD) was met by 48 of 75 patients (64%), and the goal for quality of life was met by 65 of 103 patients (63%). Bone pain was the parameter with the lowest level of achievement (goal met by 50/94 patients; 53%). The clinical information most often missing from patient records was the BMD Z-score (missing for 31% of patients). These data suggest that most Spanish GD1 patients have good control over hematological and visceral parameters, but there is a need to improve monitoring and treatment of GD-related bone disease.

The diagnostic accuracy of cardiac ultrasound for acute myocardial ischemia in the emergency department: a systematic review and meta-analysis.

BACKGROUND: Chest pain is responsible for millions of visits to the emergency department (ED) annually. Cardiac ultrasound can detect ischemic changes, but varying accuracy estimates have been reported in previous studies. We synthetized the available evidence to yield more precise estimates of the accuracy of cardiac ultrasound for acute myocardial ischemia in patients with chest pain in the ED and to assess the effect of different clinical characteristics on test accuracy. METHODS: A systematic search for studies assessing the diagnostic accuracy of cardiac ultrasound for myocardial ischemia in the ED was conducted in MEDLINE, EMBASE, CENTRAL, CINAHL, LILACS, Web of Science, two trial registries and supplementary methods, from inception to December 6th, 2022. Prospective cohort, cross-sectional, case-control studies and randomized controlled trials (RCTs) that included data on diagnostic accuracy were included. Risk of bias was assessed with the QUADAS-2 tool and a bivariate hierarchical model was used for meta-analysis with paired Forest and SROC plots used to present the results. Subgroup analyses was conducted on clinically relevant factors. RESULTS: Twenty-nine studies were included, with 5043 patients. The overall summary sensitivity was 79.3% (95%CI 69.0-86.8%) and specificity was 87.3% (95%CI 79.9-92.2%), with substantial heterogeneity. Subgroup analyses showed increased sensitivity in studies where ultrasound was conducted at ED admission and increased specificity in studies that excluded patients with previous heart disease, when the target condition was acute coronary syndrome, or when final chart review was used as the reference standard. There was very low certainty in the results based on serious risk of bias and indirectness in most studies. CONCLUSIONS: Cardiac ultrasound may have a potential role in the diagnostic pathway of myocardial ischemia in the ED; however, a pooled accuracy must be interpreted cautiously given substantial heterogeneity and that important patient and test characteristics affect its diagnostic performance.
