Predictive factors for decompensating events in patients with cirrhosis with primary biliary cholangitis under different lines of therapy.

BACKGROUND AND AIMS: The landscape in primary biliary cholangitis (PBC) has changed with the advent of second-line treatments. However, the use of obeticholic acid (OCA) and fibrates in PBC-related cirrhosis is challenging. We assessed the impact of receiving a second-line therapy as a risk factor for decompensated cirrhosis in a real-world population with cirrhosis and PBC, and identify the predictive factors for decompensated cirrhosis in these patients. APPROACH AND RESULTS: Multicenter study enrolling 388 patients with PBC-cirrhosis from the Spanish ColHai registry. Biopsy (20%), ultrasound (59%), or transient elastography (21%) defined cirrhosis, and the presence of varices and splenomegaly defined clinically significant portal hypertension (CSPH). Paris-II and PBC OCA international study of efficacy criteria determined the response to ursodeoxycholic acid (UDCA), fibrates (n=93), and OCA (n=104). The incidence of decompensated cirrhosis decreased for UDCA versus OCA or fibrates in the real-world population, but they were similar considering the propensity score-matched cohort (UDCA 3.77 vs. second-line therapy 4.5 100 persons-year, respectively), as patients on second-line therapy exhibited advanced liver disease. Consequently, GGT, albumin, platelets, clinically significant portal hypertension, and UDCA response were associated with a decompensating event. OCA response (achieved in 52% of patients) was associated with bilirubin (OR 0.21 [95% CI: 0.06-0.73]) and AST (OR 0.97 [95% CI: 0.95-0.99]), while fibrate response (achieved in 55% of patients) with AST [OR 0.96 (95% CI: 0.95-0.98]). In patients treated with OCA, drug response (sHR 0.23 [95% CI: 0.08-0.64]), diabetes (sHR 5.62 [95% CI: 2.02-15.68]), albumin (sHR 0.34 [95% CI: 0.13-0.89]), and platelets (sHR 0.99 [95% CI: 0.98-1.00]) were related to decompensation. In patients treated with fibrate, drug response (sHR 0.36 (95% CI: 0.14-0.95]), albumin (sHR 0.36 (95% CI: 0.16-0.81]), and clinically significant portal hypertension (sHR 3.70 (95% CI: 1.17-11.70]) were associated with decompensated cirrhosis. CONCLUSIONS: Advanced PBC, rather than OCA and fibrates, was found to be associated with decompensating events. Therefore, biochemical and clinical variables should be considered when making decisions about the management of these drugs. Moreover, a positive response to OCA and fibrates reduced the risk of decompensation.

Intoxicación severa por 3,4-metilendioximetanfetamina (MDMA). Reporte de caso

La intoxicación por 3,4-metilendioximetanfetamina (MDMA), ha tenido un dramático resurgimiento desde 1980, se ha extendido por gran parte de los Estados Unidos, Europa y América, ha sido ampliamente utilizada como drogas con fines recreativos, actualmente Las catinonas sintéticas se venden como "euforizantes legales" para eludir las leyes existentes, lo que resulta en toxicidad grave y muertes. Presentamos un caso clínico de un adulto joven, quien debuto con intoxicación aguda severa MDMA, con falla multiorgánica, el cual se realizó atención y manejo agudo de la intoxicación en el servicio de urgencias, con posterior manejo de complicaciones en la unidad de cuidados intensivo y finalmente con sobrevida a pesar del mal pronóstico.

3,4-methylenedioxymethamphetamine (MDMA) intoxication, has had a dramatic resurgence since 1980, has spread throughout much of the United States, Europe and America, has been widely used as a recreational drug, currently Synthetic cathinones are they sell as "legal highs" to circumvent existing laws, resulting in severe toxicity and deaths. We present a clinical case of a young adult, who debuted with severe acute MDMA poisoning, with multiple organ failure, who underwent care and acute management of the poisoning in the emergency department, with subsequent management of complications in the intensive care unit and finally with survival despite the poor prognosis.

Lower reproductive rates of Asian citrus psyllid (Hemiptera: Psyllidae) on 'Tahiti' acid lime than on 'Valencia' sweet orange

ABSTRACT The 'Tahiti' acid lime and orange trees are hosts of 'Candidatus Liberibacter asiaticus' (CLas), the pathogen associated with the severe Asian form of huanglongbing (HLB), the most devasting citrus disease. They are also hosts of the vector of CLas, the Asian citrus psyllid (ACP) Diaphorina citri Kuwayama. Relatively small numbers of lime trees occur in gardens and small orchards near large commercial 'Valencia' sweet orange orchards in Brazil. Applications of insecticides to suppress populations of ACP on the lime trees are usually nil or less frequent than in the orange orchards. Abundance of the psyllid on lime trees may therefore increase the risk of CLas spreading to the orchards. Because the abundance of the psyllid is influenced by the suitability of the trees as hosts, we compared reproductive potential of the insect on the two hosts in a controlled environment chamber (CEC) and in a greenhouse (GH). Daily temperature and relative humidity averaged 22ºC and 60% inside the CEC and 24°C and 70% inside the GH. Two pairs of adult male and female psyllids were caged for 3 days on new shoots and the fecundity and durations of development and survival of eggs and nymphs evaluated. Overall, acid 'Tahiti' was 3.5 times less suitable to ACP than 'Valencia'. Fecundity and survival of nymphs were 27% and 59% lower, and the life cycle 34% longer on 'Tahiti' than on 'Valencia'. Potential impacts of the results on CLas spread and HLB control are discussed.

Diagnosis and treatment of coagulopathy using thromboelastography with platelet mapping is associated with decreased risk of pulmonary failure in COVID-19 patients.

INTRODUCTION: Treatment of coronavirus disease 2019 (COVID-19) patients may require antithrombotic and/or anti-inflammatory medications. We hypothesized that individualized anticoagulant (AC) management, based on diagnosis of coagulopathy using thromboelastography with platelet mapping (TEG-PM), would decrease the frequency of pulmonary failure (PF) requiring mechanical ventilation (MV), mitigate thrombotic and hemorrhagic events, and, in-turn, reduce mortality. METHODS: Hospital-admitted COVID-19 patients, age 18 or older, with escalating oxygen requirements were included. Prospective and supplemental retrospective chart reviews were conducted during a 2-month period. Patients were stratified into two groups based on clinician-administered AC treatment: TEG-PM guided vs. non-TEG guided. RESULTS: Highly-elevated inflammatory markers (D-dimer, C-reactive protein, ferritin) were associated with poor prognosis but did not distinguish coagulopathic from noncoagulopathic patients. TEG-guided AC treatment was used in 145 patients vs. 227 treated without TEG-PM guidance. When managed by TEG-PM, patients had decreased frequency of PF requiring MV (45/145 [31%] vs. 152/227 [66.9%], P  < 0.0001), fewer thrombotic events (2[1.4%] vs. 39[17.2%], P  = 0.0019) and fewer hemorrhagic events (6[4.1%] vs. 24[10.7%], P  = 0.0240), and had markedly reduced mortality (43[29.7%] vs. 142[62.6%], P  < 0.0001). Platelet hyperactivity, indicating the need for antiplatelet medications, was identified in 75% of TEG-PM patients. When adjusted for confounders, empiric, indiscriminate AC treatment (not guided by TEG-PM) was shown to be an associated risk factor for PF requiring MV, while TEG-PM guided management was associated with a protective effect (odds ratio = 0.18, 95% confidence interval 0.08-0.4). CONCLUSIONS: Following COVID-19 diagnosis, AC therapies based on diagnosis of coagulopathy using TEG-PM were associated with significantly less respiratory decompensation, fewer thrombotic and hemorrhagic complications, and improved likelihood of survival.

Microwave-sensor-node integrated into a short-range wireless sensor network.

This paper presents the first microwave-sensor-node integrated into a short-range wireless sensor network based on ZigBee technology. The node includes an analog front-end circuit, a Frequency Modulated Continuous Wave generator, an Analog-to-Digital-Converter module, a transceiver, a power unit, a processing unit and a new one-port dielectric permittivity sensor which is able to measuring the separation of structural cracks by the reflection coefficient measured in microwave frequencies. The analog front-end is composed of a pair of power dividers, an isolator and a mixer. The dielectric permittivity sensor is based on a patch antenna of variable length. The processing unit and transceiver are implemented with an Arduino UNO and an XBee module respectively. Additionally, the methodology for data processing is presented and the results of the measurement of a synthetic crack are presented. The results show that the system was successfully implemented with a sensitivity of 0.07 GHz/mm, for an opening range of between 0 and 5 mm and for a frequency range ranging from 2.782 GHz to 3.131 GHz. It is important to mention that the measurement was done remotely, placing the sensor 3 m from the client PC.

Tenofovir Disoproxil Fumarate Reduces the Severity of COVID-19 in Patients with Chronic Hepatitis B.

BACKGROUND AND AIMS: HIV-positive patients on tenofovir hydroxyl fumarate (TDF)/emtricitabine have a lower risk of COVID-19 and hospitalization than those given other treatments. Our aim was to analyze the severity of COVID-19 in patients with chronic hepatitis B (CHB) on TDF or entecavir (ETV). METHODS: Spanish hospital databases (n = 28) including information regarding adult CHB patients on TDF or ETV for the period February 1st to November 30th 2020 were searched for COVID-19, defined as a positive SARS-CoV-2 polymerase chain reaction, and for severe COVID-19. RESULTS: Of 4736 patients, 117 had COVID-19 (2.5%), 67 on TDF and 50 on ETV. Compared to patients on TDF, those on ETV showed (p < 0.05) greater rates of obesity, diabetes, ischemic cardiopathy, and hypertension. COVID-19 incidence was similar in both groups (2.3 vs. 2.6%). Compared to TDF, patients on ETV more often (p < 0.01) had severe COVID-19 (36 vs. 6%), required intensive care unit (ICU) (10% vs. 0) or ventilatory support (20 vs. 3%), were hospitalized for longer (10.8 ± 19 vs. 3.1 ± 7 days) or died (10 vs. 1.5%, p = 0.08). In an IPTW propensity score analysis adjusted for age, sex, obesity, comorbidities, and fibrosis stage, TDF was associated with a sixfold reduction in severe COVID-19 risk (adjusted-IPTW-OR 0.17, 95%CI 0.04-0.67, p = 0.01). CONCLUSION: Compared to ETV, TDF seems to play a protective role in CHB patients with SARS-CoV-2 whereby the risk of severe COVID-19 is lowered.

Impacts of huanglongbing on fruit yield and quality and on flushing dynamics of Sicilian lemon trees.

Introduction: The severe Asian form of huanglongbing (HLB), a vascular disease associated with the phloem-limited bacterium 'Candidatus Liberibacter asiaticus', is transmitted by the Asian citrus psyllid (ACP) Diaphorina citri. Disease impacts are known for sweet oranges and acid limes but not lemons. Methods: In a five-year study (2017-2021) we compared yield and fruit quality between naturally-infected and healthy 5-yr-old trees of Sicilian lemon 'Femminello', and shoot phenology on both lemon and 'Valencia' orange, both grafted onto 'Swingle' citrumelo, grown in southeastern São Paulo State, Brazil. HLB severity (percentage of tree canopy area with HLB symptoms) was assessed every 3-4 months, fruit yield and quality in May (2017 to 2019) or June/July (2020-2021), and vegetative and reproductive shoots fortnightly on 50-cm-long branches. The development of ACP on one-year-old seedlings of five lemon varieties, 'Tahiti' acid lime, 'Valencia' orange, and orange jasmine was evaluated. Results: Symptoms increased from 11% in 2017 to 64% in 2021, and a monomolecular model estimated 10 years for symptoms to occupy >90% of the tree canopy. On average, production of trees with symptom on 20%, 50% or 80% of the canopy respectively dropped by 18%, 38%, and 53% compared to healthy trees. Fruits of symptomatic branches of lemons were 4.22% lighter and the number of dropped fruits did not correlate with symptom severity. Flushing on symptomatic branches started earlier by 15 to 55 days as compared to the healthy branches of lemon and orange. On diseased trees, vegetative and reproductive shoots respectively increased by 24.5% and 17.5% on lemon and by 67.2% and 70.6% on sweet orange, but fruit set was reduced by 12.9% and 19.7% on lemon and orange trees, respectively. ACP reproduced similarly on all tested plants. Discussion: The fast symptom progress, significant yield reduction, and earlier flushing on diseased trees, providing conditions highly favorable for the pathogen to spread, reinforce the need of prompt diseased tree removal and frequent ACP preventive control to manage HLB in lemons as in any other citrus crop.

Review of Sarcopenia and Testosterone Deficiency With Chronic Liver Disease and Postoperative Liver Transplant Utility of Short-Term Testosterone Replacement Therapy.

OBJECTIVES: Chronic liver disease is often associated with testosterone deficiency. However, testosterone replacement does not improve hepatic function or survival with diseased liver. So far, to our knowledge, testosterone replacement therapy after successful livertransplantforfunctional sarcopenia has not been studied. We had 3 goals: (1) define postoperative functional sarcopenia afterlivertransplant with serum testosterone level; (2) examine the role of short-term testosterone replacement therapy with active in-bed exercise of upper and lower extremity joints; and (3) correlate functional sarcopenia with skeletal muscle index and skeletal muscle density in relation to ascites, pleural effusion subtracted body mass index. MATERIALS AND METHODS: We evaluated 16 liver transplant recipients who had been receiving posttransplanttestosterone replacementtherapy with functional sarcopenia. Preoperative and postoperative demographics and laboratory and radiological data were retrieved; body mass index, skeletal muscle index, and skeletal muscle density were calculated. For this retrospective study, institutional review board approval was obtained before the electronic database was reviewed and analyzed. RESULTS: Mean testosterone level was 28.3 ng/dL (<5% of expected). Twelve patients received 1 dose, and the remaining 4 patients received >1 dose oftestosterone cypionate, 200 mg. Mean hospital stay was 26 days. Seven patients were discharged home, with the remaining patients to a rehabilitation facility or nursing home. One patient died from a cardiac event, and another patient died from recurrent metastatic malignancy. The 1-year and 5-year actuarial patient and graft survival rates were 93.8% and 87.5%, respectively. Overall, 5 patients were sarcopenic by skeletal muscle index, and 6 patients had poor muscle quality by skeletal muscle density. CONCLUSIONS: Testosterone deficiency after liver transplant exists with functional sarcopenia. Two- thirds of such recipients have low skeletal muscle index and/or have low skeletal muscle density. Short- term testosterone replacement therapy with in-bed active exercise provides 5-year patient and graft survival of 87.5%.

Nivolumab after selective internal radiation therapy for the treatment of hepatocellular carcinoma: a phase 2, single-arm study.

PURPOSE: To evaluate the safety and efficacy of selective internal radiation therapy (SIRT) in combination with a PD-1 inhibitor in patients with unresectable hepatocellular carcinoma (uHCC) and liver-only disease ineligible for chemoembolization. PATIENTS AND METHODS: NASIR-HCC is a single-arm, multicenter, open-label, phase 2 trial that recruited from 2017 to 2019 patients who were naïve to immunotherapy and had tumors in the BCLC B2 substage (single or multiple tumors beyond the up-to-7 rule), or unilobar tumors with segmental or lobar portal vein invasion (PVI); no extrahepatic spread; and preserved liver function. Patients received SIRT followed 3 weeks later by nivolumab (240 mg every 2 weeks) for up to 24 doses or until disease progression or unacceptable toxicity. Safety was the primary endpoint. Secondary objectives included objective response rate (ORR), time to progression (TTP), and overall survival (OS). RESULTS: 42 patients received SIRT (31 BCLC-B2, 11 with PVI) and were followed for a median of 22.2 months. 27 patients discontinued and 1 never received Nivolumab. 41 patients had any-grade adverse events (AE) and 21 had serious AEs (SAE). Treatment-related AEs and SAEs grade 3-4 occurred in 8 and 5 patients, respectively. Using RECIST 1.1 criteria, ORR reported by investigators was 41.5% (95% CI 26.3% to 57.9%). Four patients were downstaged to partial hepatectomy. Median TTP was 8.8 months (95% CI 7.0 to 10.5) and median OS was 20.9 months (95% CI 17.7 to 24.1). CONCLUSIONS: The combination of SIRT and nivolumab has shown an acceptable safety profile and signs of antitumor activity in the treatment of patients with uHCC that were fit for SIRT. TRIAL REGISTRATION NUMBER: NCT03380130.

Ethnicity and Nonsurgical Rhinoplasty.

Background: Nonsurgical rhinoplasty is a procedure that is gaining popularity in aesthetic clinics particularly because of its minimally invasive nature compared with surgery. It is recognized that there are ethnic variations in nose injection techniques and planned aesthetic outcomes. Objectives: The objective of this study was to explore experts' views about the ethnic differences in the anatomical features of the nose and procedure-related considerations in nonsurgical rhinoplasty. Methods: Using a priori set topics and questions, 4 expert aesthetic physicians, from 4 different ethnic backgrounds and working in 4 different regions, were asked to describe the essential elements to be considered when planning a nonsurgical rhinoplasty, including product choice, injection technique, safety measures, and any practical hints to facilitate achieving the desired outcome. Results: All invited experts responded to the full set of questions. There were similarities between the treating physicians in some of the technical steps. Nevertheless, there were several differences identified regarding baseline anatomy and patient expectations that could be attributed to ethnicity. Patients' and physicians' expectations regarding a successful nonsurgical rhinoplasty can vary depending on their ethnic backgrounds. Therefore, with the current global ethnic and cultural diversities, in addition to the knowledge of the nasal anatomy and safe injection techniques, it is imperative that aesthetic practitioners have full awareness and a good understanding of these ethnic variations. Conclusions: Nonsurgical rhinoplasty is a highly demanded aesthetic procedure. Patients' ethnic differences need to be carefully taken into consideration when discussing, planning, and performing nasal fillers injection.

Effect of physiotherapy on the promotion of bone mineralization in preterm infants: a randomized controlled trial.

Preterm infants have a low level of bone mineralization compared to those born at term. The purpose of the present study was to investigate the effect of reflex locomotion therapy (RLT) on bone mineralization and growth in preterm infants and compare its effect to other physiotherapy procedures. Forty-six preterm infants born at 29-34 weeks were randomized into three groups: one group received RLT (n = 17); the other group received passive movements with gentle joint compression (n = 14); and the control group received massages (n = 15). All the treatments were performed at the neonatal unit for one month. The main outcome measure was bone mineralization, which was measured using the tibial speed of sound (Tibial-SOS). All the groups were similar in terms of gestational age (31.8 ± 1.18), birth weight (1,583.41 ± 311.9), and Tibia-SOS (1,604.7 ± 27.9) at the beginning of the intervention. At the end of the study, significant differences were found among the groups in the Tibial-SOS [F(4,86) = 2.77, p = 0.049, ηp2 = 0.114] in terms of the benefit to the RLT group. In conclusion, RLT has been effective at improving Tibial-SOS levels and has been more effective than other physical therapy modalities; therefore, it could be considered an effective physiotherapeutic modality for the prevention and treatment of osteopenia from prematurity.

Health Needs Assessment: Chronic Kidney Disease Secondary to Type 2 Diabetes Mellitus in a Population without Social Security, Mexico 2016-2032.

Health needs assessment is a relevant tracer of planning process of healthcare programs. The objective is to assess the health needs of chronic kidney disease (CKD) secondary to type 2 diabetes mellitus (T2 DM) in a population without social security in Mexico. The study design was a statistical simulation model based on data at the national level of Mexico. A stochastic Markov model was used to simulate the progression from diabetes to CKD. The time horizon was 16 years. The results indicate that in 2022, kidney damage progression and affectation in the diabetic patient cohort will be 34.15% based on the time since T2 DM diagnosis. At the end of the 16-year period, assuming that the model of care remains unchanged, early renal involvement will affect slightly more than twice as many patients (118%) and cases with macroalbuminuria will triple (228%). The need for renal replacement therapy will more than double (169%). Meanwhile, deaths associated with cardiovascular risk will more than triple (284%). We concluded that the clinical manifestations of patients with CKD secondary to T2 DM without social security constitute a double challenge. The first refers to the fact that the greatest health need is early care of CKD, and the second is the urgent need to address cardiovascular risk in order to reduce deaths in the population at risk.

Impact of GST thickness on GST-loaded silicon waveguides for optimal optical switching.

Phase-change integrated photonics has emerged as a new platform for developing photonic integrated circuits by integrating phase-change materials like GeSbTe (GST) onto the silicon photonics platform. The thickness of the GST patch that is usually placed on top of the waveguide is crucial for ensuring high optical performance. In this work, we investigate the impact of the GST thickness in terms of optical performance through numerical simulation and experiment. We show that higher-order modes can be excited in a GST-loaded silicon waveguide with relatively thin GST thicknesses (<100 nm), resulting in a dramatic reduction in the extinction ratio. Our results would be useful for designing high-performance GST/Si-based photonic devices such as non-volatile memories that could find utility in many emerging applications.

Effect of physical therapy on bone remodelling in preterm infants: a multicenter randomized controlled clinical trial.

BACKGROUND: Preterm infants have a low level of bone mineralization compared to those born at term, since 80% of calcium incorporation occurs at the end of pregnancy. The purpose of the present study was to investigate the effect of reflex locomotion therapy on bone modeling and growth in preterm infants and to compare its effect with those of other Physiotherapy modalities. METHODS: A multicentre randomized controlled clinical trial was conducted (02/2016 - 07/2020). 106 preterm infants born at the Virgen de la Arrixaca University Clinical Hospital, the General University Hospital of Elche and the Torrecárdenas University Hospital of Almería, between 26 and 34 weeks with hemodynamic stability, complete enteral nutrition and without any metabolic, congenital, genetic, neurological or respiratory disorders were evaluated for inclusion. Infants were randomly assigned to three groups: one group received reflex locomotion therapy (EGrlt); another group received passive mobilizations with gentle joint compression (EGpmc); and the control group received massage (CG). All treatments were carried out in the neonatal units lasting one month. The main outcome measure was bone formation and resorption measured with bone biomarkers. A mixed ANOVA was used to compare the results of bone biomarkers, and anthropometric measurements. RESULTS: Infants were randomized to EGrlt (n = 38), EGpmc (n = 32), and CG (n = 36). All groups were similar in terms of gender (p = 0.891 female 47.2%), gestational age (M = 30.753, SD = 1.878, p = 0.39) and birth weight (M = 1413.45, SD = 347.36, p = 0.157). At the end of the study, significant differences were found between the groups in their interaction in bone formation, measured with osteocalcin [F (2,35) = 4.92, p = 0.013, ηp2 = 0.043], in benefit of the EGrlt. CONCLUSIONS: Reflex locomotion therapy has been effective in improving bone formation, more so than other Physiotherapy modalities. Therefore, reflex locomotion therapy could be considered one of the most effective physiotherapeutic modalities for the prevention and treatment of osteopenia of prematurity. TRIAL REGISTRSTION: Trial retrospectively registered at ClinicalTrials.gov. First posted on 22/04/2020. REGISTRATION NUMBER: NCT04356807 .

Ultrafast all-optical phase switching enabled by epsilon-near-zero materials in silicon.

Transparent conducting oxides (TCOs) have emerged as both particularly appealing epsilon-near-zero (ENZ) materials and remarkable candidates for the design and fabrication of active silicon nanophotonic devices. However, the leverage of TCO's ultrafast nonlinearities requires precise control of the intricate physical mechanisms that take place upon excitation. Here we investigate such behavior for ultrafast all-optical phase switching in hybrid TCO-silicon waveguides through numerical simulation. The model is driven from the framework of intraband-transition-induced optical nonlinearity. Transient evolution is studied with a phenomenological two-temperature model. Our results reveal the best compromise between energy consumption, insertion losses and phase change per unit length for enabling ultrafast switching times below 100 fs and compact active lengths in the order of several micrometers.

Consenso multidisciplinar para el manejo de la tromboembolia de pulmón / Multidisciplinary Consensus for the Management of Pulmonary Thromboembolism

El objetivo del presente documento es actualizar el consenso previo publicado en 2013, en relación con 12 áreas controvertidas en el manejo de la tromboembolia de pulmón (TEP). Para cada área se realizó una exhaustiva revisión bibliográfica y una propuesta de recomendación, sometida a un proceso de debate interno en dos teleconferencias sucesivas. En relación con el diagnóstico, recomendamos no utilizar la escala Pulmonary Embolism Rule Out Criteria (PERC) de forma aislada para descartar la TEP y, cuando haya indicación de dímero D, recomendamos emplear un punto de corte ajustado a la edad. Sugerimos utilizar la angiotomografía computerizada de tórax como prueba de imagen para el diagnóstico de la mayoría de los pacientes con sospecha de la enfermedad. Se recomienda utilizar anticoagulantes de acción directa (en vez de antagonistas de la vitamina K) para el tratamiento de la mayoría de los pacientes con TEP, y se sugiere utilizar anticoagulación para la mayoría de los pacientes con TEP subsegmentaria. Se recomienda no colocar un filtro de vena cava inferior en la mayoría de los pacientes. Si se indica tratamiento de reperfusión, el panel recomienda utilizar fibrinolisis sistémica a dosis completas. La duración de la anticoagulación está condicionada principalmente por la presencia (o ausencia) y el tipo de factor de riesgo para enfermedad tromboembólica venosa, y recomendamos no realizar estudios de trombofilia para decidir la duración de la anticoagulación a la mayoría de los pacientes con TEP. Finalmente, sugerimos no realizar cribado extendido de cáncer oculto en pacientes con TEP. (AU)

We have updated recommendations on 12 controversial topics that were published in the 2013 National Consensus on the diagnosis, risk stratification and treatment of patients with pulmonary embolism (PE). A comprehensive review of the literature was performed for each topic, and each recommendation was evaluated in two teleconferences. For diagnosis, we recommend against using the Pulmonary Embolism Rule Out Criteria (PERC) rule as the only test to rule out PE, and we recommend using a D-dimer cutoff adjusted to age to rule out PE. We suggest using computed tomography pulmonary angiogram as the imaging test of choice for the majority of patients with suspected PE. We recommend using direct oral anticoagulants (over vitamin K antagonists) for the vast majority of patients with acute PE, and we suggest using anticoagulation for patients with isolated subsegmental PE. We recommend against inserting an inferior cava filter for the majority of patients with PE, and we recommend using full-dose systemic thrombolytic therapy for PE patients requiring reperfusion. The decision to stop anticoagulants at 3 months or to treat indefinitely mainly depends on the presence (or absence) and type of risk factor for venous thromboembolism, and we recommend against thrombophilia testing to decide duration of anticoagulation. Finally, we suggest against extensive screening for occult cancer in patients with PE. (AU)
