Mutational spectrum and genotype-phenotype correlation in Mexican patients with infantile-onset and late-onset Pompe disease.

BACKGROUND: Pompe Disease (PD) is a metabolic myopathy caused by variants in the GAA gene, resulting in deficient enzymatic activity. We aimed to characterize the clinical features and related genetic variants in a series of Mexican patients. METHODS: We performed a retrospective study of clinical records of patients diagnosed with LOPD, IOPD or pseudodeficiency. RESULTS: Twenty-nine patients were included in the study, comprising these three forms. Overall, age of symptom onset was 0.1 to 43 years old. The most frequent variant identified was c.-32-13T>G, which was detected in 14 alleles. Among the 23 different variants identified in the GAA gene, 14 were classified as pathogenic, 5 were likely pathogenic, and 1 was a variant of uncertain significance. Two variants were inherited in cis arrangement and 2 were pseudodeficiency-related benign alleles. We identified two novel variants (c.1615 G>A and c.1076-20_1076-4delAAGTCGGCGTTGGCCTG). CONCLUSION: To the best of our knowledge, this series represent the largest phenotypic and genotypic characterization of patients with PD in Mexico. Patients within our series exhibited a combination of LOPD and IOPD associated variants, which may be related to genetic diversity within Mexican population. Further population-wide studies are required to better characterize the incidence of this disease in Mexican population.

Effectiveness and safety of once-weekly semaglutide: findings from the SEMACOL-REAL retrospective multicentric observational study in Colombia.

Introduction: Diabetes stands as one of the leading causes of death worldwide. Glucagon-like peptide-1 receptor agonists rank among the most effective medications for lowering blood glucose and body weight, as well as reducing cardiovascular risk in individuals with diabetes. Observational studies complement experimental evidence in new settings, different populations, and real-world healthcare practices. Methods: A multicentric observational study of adults with type 2 diabetes treated with once-weekly subcutaneous semaglutide in four health centers in Colombia was conducted. The protocol for the present study was not pre-registered. Results: Data from 186 patients were included. Most patients were women (57%) with a mean age of 62.8 ± 12.1 years. One year of once-weekly semaglutide usage was associated with a mean reduction in HbA1C of -1.47% (95% CI -1.76, -1.17), weight loss of -4.23 kg (95% CI -5.34, -3.12), and albumin/creatinine ratio of -18.6 mg/g (95% CI -60.2, -5.9). Approximately half the treated patients achieved a level of HbA1c ≤7% by the end of follow-up. Adverse events were rare and consistent with clinical trial safety profiles. Conclusion: In Colombia, administering semaglutide subcutaneously once a week over a 1-year period led to an average weight loss of 4.2 kg and a decrease of 1.4% in HbA1c.

Spinal Muscular Atrophy Update in Best Practices: Recommendations for Diagnosis Considerations.

Background and Objectives: Spinal muscular atrophy (SMA) is an autosomal recessive progressive neurodegenerative primary motor neuron disorder caused by biallelic variants of the survival motor neuron 1 (SMN1) gene. The most recent SMA best practice recommendations were published in 2018 shortly after the approval of the first SMN-enhancing treatment. The availability of disease-modifying therapies for 5q SMA and implementation of SMA newborn screening (NBS) has led to urgency to update the SMA best practice recommendations for diagnosis and to reevaluate the current classification of SMA. In addition, the availability of disease-modifying therapies has opened the door to explore improved diagnosis of adult-onset SMA. Methods: A systematic literature review was conducted on SMA NBS. An SMA working group of American and European health care providers developed recommendations through a modified Delphi technique with serial surveys and virtual meeting feedback on SMA diagnosis to fill information gaps for topics with limited evidence. A community working group of an individual with SMA and caregivers provided insight and perspective on SMA diagnosis and support through a virtual meeting to guide recommendations. Results: The health care provider working group achieved consensus that SMA NBS is essential to include in the updated best practice for SMA diagnosis (100%). Recommendations for the following are described: characterizing NBS-identified infants before treatment; minimum recommendations for starting or offering SMA NBS in a state or country; recommendations for activities and services to be provided by an SMA specialty care center accepting SMA NBS referrals; and recommendations for partnership with individuals with SMA and caregivers to support NBS-identified infants and their caregivers. Limited data are available to advance efficient diagnosis of adult-onset SMA. Discussion: Updating best practice recommendations for SMA diagnosis to include SMA NBS implementation is essential to advancing care for individuals with SMA. In addition to testing, processes for the efficient management of positive newborn screen with access to knowledgeable and skilled health care providers and access to treatment options is critical to successful early diagnosis. Additional evidence is required to improve adult-onset SMA diagnosis.

A Systematic Review and Meta-Analysis on the Prevalence of Mild Cognitive Impairment and Dementia in Mexico.

INTRODUCTION: Age remains one of the major risk factors for the onset of mild cognitive impairment (MCI) and dementia. Studies on the prevalence of these conditions in Mexico used different methods, tools, and populations with different health statuses. All these heterogeneous results may be a problem in identifying the true prevalence of MCI and dementia in Mexico. To our knowledge, there is not a systematic review available that presents essential figures on the prevalence of these conditions in Mexico. Therefore, we intend to access the maximum number of reports published on the topic and determine the prevalence of MCI and dementia in older Mexican adults. METHODS: A systematic review using PubMed, Cochrane, Research Gate, Lilacs, and Scielo databases was performed. Meta-analysis of the prevalence of MCI and dementia was performed using a random-effects model and presented in a forest plot among cross-sectional, epidemiological, and pooled studies. RESULTS: Sixteen articles were included. The overall prevalence of MCI of 18% (95% CI 0.10-0.27) was estimated from pooled information from 12 selected studies, in women 21% (95% CI 0.08-0.38) and in men 18% (95% CI 0.06-0.33). The overall prevalence of dementia of 10% (95% CI 0.06-0.14) was estimated from pooled information from 9 selected studies, in women 14% (95% CI 0.05-0.25) and in men 10% (95% CI 0.04-0.17). CONCLUSION: Mexican older individuals have a similar prevalence of dementia and MCI as reported by international data; nevertheless, the prevalence is higher than in some Latin American countries. Mexico has particular issues that must be resolved, such as a lack of research in the southern regions of the country and the high incidence of comorbidities.

Head-to-toe bedside ultrasound for adult patients on extracorporeal membrane oxygenation.

Bedside ultrasound represents a well-suited diagnostic and monitoring tool for patients on extracorporeal membrane oxygenation (ECMO) who may be too unstable for transport to other hospital areas for diagnostic tests. The role of ultrasound, however, starts even before ECMO initiation. Every patient considered for ECMO should have a thorough ultrasonographic assessment of cardiac and valvular function, as well as vascular anatomy without delaying ECMO cannulation. The role of pre-ECMO ultrasound is to confirm the indication for ECMO, identify clinical situations for which ECMO is not indicated, rule out contraindications, and inform the choice of ECMO configuration. During ECMO cannulation, the use of vascular and cardiac ultrasound reduces the risk of complications and ensures adequate cannula positioning. Ultrasound remains key for monitoring during ECMO support and troubleshooting ECMO complications. For instance, ultrasound is helpful in the assessment of drainage insufficiency, hemodynamic instability, biventricular function, persistent hypoxemia, and recirculation on venovenous (VV) ECMO. Lung ultrasound can be used to monitor signs of recovery on VV ECMO. Brain ultrasound provides valuable diagnostic and prognostic information on ECMO. Echocardiography is essential in the assessment of readiness for liberation from venoarterial (VA) ECMO. Lastly, post decannulation ultrasound mainly aims at identifying post decannulation thrombosis and vascular complications. This review will cover the role of head-to-toe ultrasound for the management of adult ECMO patients from decision to initiate ECMO to the post decannulation phase.

Efficacy and Safety of Vamorolone Over 48 Weeks in Boys With Duchenne Muscular Dystrophy: A Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: Vamorolone is a dissociative agonist of the glucocorticoid receptor that has shown similar efficacy and reduced safety concerns in comparison with prednisone in Duchenne muscular dystrophy (DMD). This study was conducted to determine the efficacy and safety of vamorolone over 48 weeks and to study crossover participants (prednisone to vamorolone; placebo to vamorolone). METHODS: A randomized, double-blind, placebo-controlled and prednisone-controlled clinical trial of 2 doses of vamorolone was conducted in participants with DMD, in the ages from 4 years to younger than 7 years at baseline. The interventions were 2 mg/kg/d of vamorolone and 6 mg/kg/d of vamorolone for 48 weeks (period 1: 24 weeks + period 2: 24 weeks) and 0.75 mg/kg/d of prednisone and placebo for the first 24 weeks (before crossover). Efficacy was evaluated through gross motor outcomes and safety through adverse events, growth velocity, body mass index (BMI), and bone turnover biomarkers. This analysis focused on period 2. RESULTS: A total of 121 participants with DMD were randomized. Vamorolone at a dose of 6 mg/kg/d showed maintenance of improvement for all motor outcomes to week 48 (e.g., for primary outcome, time to stand from supine [TTSTAND] velocity, week 24 least squares mean [LSM] [SE] 0.052 [0.0130] rises/s vs week 48 LSM [SE] 0.0446 [0.0138]). After 48 weeks, vamorolone at a dose of 2 mg/kg/d showed similar improvements as 6 mg/kg/d for North Star Ambulatory Assessment (NSAA) (vamorolone 6 mg/kg/d-vamorolone 2 mg/kg/d LSM [SE] 0.49 [1.14]; 95% CI -1.80 to 2.78, p = 0.67), but less improvement for other motor outcomes. The placebo to vamorolone 6 mg/kg/d group showed rapid improvements after 20 weeks of treatment approaching benefit seen with 48-week 6 mg/kg/d of vamorolone treatment for TTSTAND, time to run/walk 10 m, and NSAA. There was significant improvement in linear growth after crossover in the prednisone to vamorolone 6 mg/kg/d group, and rapid reversal of prednisone-induced decline in bone turnover biomarkers in both crossover groups. There was an increase in BMI after 24 weeks of treatment that then stabilized for both vamorolone groups. DISCUSSION: Improvements of motor outcomes seen with 6 mg/kg/d of vamorolone at 24 weeks of treatment were maintained to 48 weeks of treatment. Vamorolone at a dose of 6 mg/kg/d showed better maintenance of effect compared with vamorolone at a dose of 2 mg/kg/d for most (3/5) motor outcomes. Bone morbidities of prednisone (stunting of growth and declines in serum bone biomarkers) were reversed when treatment transitioned to vamorolone. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov Identifier: NCT03439670. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that for boys with DMD, the efficacy of vamorolone at a dose of 6 mg/kg/d was maintained over 48 weeks.

Introducción: la hipersensibilidad por fármacos es inducida por una respuesta aberrante del sistema inmune; por lo general, impredecible, dosis independiente y amenazante para la vida del paciente. Las reacciones de hipersensibilidad por fármacos con compromiso mucocutáneo se dan en alrededor del 2 %-3 % de los pacientes hospitalizados. Objetivo: describir un caso de necrólisis tóxica epidérmica por un fármaco a base de caléndula y acetilcisteína como los presuntos desencadenantes. Presentación del caso: hombre de 39 años, quien asistió a emergencias, por malestar general, artralgias, mialgias, astenia y adinamia de un día de evolución. Tres días después refirió la aparición de lesiones purpúricas progre-sivas que se extendieron por cara, extremidades y glúteos; delimitadas; no dolorosas, y sin desaparecer a la digitopresión, asociado con disnea, inestabilidad hemodinámica y cardiovascular. Al sexto día de hos-pitalización, se interrogó al paciente, quien se había automedicado un fármaco de origen desconocido, presuntamente de extracto herbal a base de caléndula más acetilcisteína para artralgias, osteomialgias y disfagia. A la mañana siguiente, presentó lesiones purpúricas y ulcerativas extensas. Se observaron lesiones purpúricas progresivas y ulcerativas en cara extremidades y glúteos. Mediante la sospecha clínica y la evaluación histopatológica, se confirmó la necrólisis tóxica epidérmica. Conclusiones: las reacciones adversas medicamentosas severas que amenazan la vida del paciente son relativamente raras, pero representan un verdadero desafío diagnóstico y terapéutico. Es necesario profundizar en la investigación para esclarecer la causa de este tipo de reacción medicamentosa.

Introduction: Drug hypersensitivity is induced by an aberrant response from the immune system. It is usually unpredictable, dose-independent, and can be life-threatening to the patient. Drug-induced hypersensitivity reactions with mucocutaneous involvement occur in approximately 2­3% of hospitalized patients. However, Toxic Epidermal Necrolysis is a rare case. Aim: To describe a case of drug-induced toxic epidermal necrolysis triggered by Calendula officinalis and acetylcysteine. Case report: A 39-year-old male was pre-sented to the emergency room with malaise, arthralgia, myalgia, asthenia, and adynamia since day one. Three days later, he developed progressive purpuric lesions that spread to the face, extremities, and buttocks. These lesions were painless, not delineate, and did not blanch under pressure. They were asso-ciated with dyspnea and hemodynamic and cardiovascular instability. On the sixth day of hospitaliza-tion, the patient admitted to self-medicating with an unknown drug, presumably a herbal extract based on calendula and acetylcysteine, for arthralgia, myalgia, and dysphagia. The morning after the drug consumption, the patient developed extensive purpuric and ulcerative lesions. A diagnosis of toxic epi-dermal necrolysis was made based on clinical suspicion and histopathological confirmation. Conclusion:Severe adverse drug reactions that threaten a patient's life are relatively rare. However, they represent a real diagnostic and therapeutic challenge when they do occur

Introdução: a hipersensibilidade a drogas é induzida por uma resposta aberrante do sistema imunoló-gico; geralmente imprevisível, independente da dose e com risco de vida para o paciente. As reações de hipersensibilidade a drogas com comprometimento mucocutâneo estão em torno dos 2-3% dos pacien-tes hospitalizados. Objetivo: descrever um caso de necrólise epidérmica tóxica causada por uma droga à base de Calendula officinalis e acetilcisteína como os supostos desencadeantes. Apresentação do caso:homem, 39 anos, deu entrada no pronto-socorro manifestando mal-estar, artralgia, mialgia, astenia e adinamia há um dia. Posteriormente, três dias depois, relatou o aparecimento de lesões purpúricas pro-gressivas que se espalharam para a face, extremidades e nádegas; que são delimitadas, não dolorosas e não desaparecem com a acupressão associada a dispnéia, instabilidade hemodinâmica e cardiovascular. No sexto dia de internação, o paciente foi questionado, y disse que tinha se automedicado com uma droga de origem desconhecida, presumivelmente extrato de ervas à base de calêndula mais acetilcis-teína para artralgia, osteomialgia e disfagia. Na manhã seguinte, apresentou extensas lesões purpúricas e ulcerativas. Observam-se lesões purpúricas progressivas e ulcerativas que se estendem à face, extre-midades e nádegas. Pela suspeita clínica e confirmação histopatológica, confirma-se a necrólise epidér-mica tóxica. Conclusões: reações adversas graves a medicamentos que ameaçam a vida do paciente são relativamente raras, mas quando ocorrem representam um verdadeiro desafio a nível diagnóstico e terapêutico. São precisas mais pesquisas para esclarecer a causa desse tipo de reação medicamentosa.

A Case of Primary Lung Adenocarcinoma With Two Uncommon Presentations: Neurological Paraneoplastic Syndrome and Pericardial Effusion.

Lung cancer is the second most common cancer worldwide and remains the first cause of cancer death. The diagnosis of lung cancer is mostly made following evaluation for respiratory signs and symptoms but sometimes the first presentation may be atypical. Some symptoms may be related to the invasion of adjacent structures and others caused by an autoimmune-mediated process when cross-reactivity between tumor antigens and normal nervous tissues is responsible for paraneoplastic syndromes. We present a case of a young woman with a smoking history who first manifested with two uncommon presentations of lung cancer: a paraneoplastic neurological syndrome and a hemorrhagic pericardial effusion with cardiac tamponade.

Septic Embolism Associated With Periodontal Disease: A Case Report.

Parvimonas micra and Provetella oralis are two commensal anaerobic bacteria of the human oral cavity. Anaerobic bacteria infections are uncommon and require a high index of suspicion and a quick start of appropriate treatment. We present a patient with multifocal infiltrates compatible with septic embolism (lung, liver, and spleen emboli) and polymicrobial bacteremia with Parvimonas micra and Provetella oralis. Periodontal disease appears to be the main cause of this disseminated infection.

Voluminous bilateral adnexal cysts in a young female: the challenge of fertility preservation.

An ovarian benign cyst is a common finding in women of reproductive age. However both the disease and its treatment may have an impact on ovarian reserve, resulting in a significant risk of premature ovarian insufficiency. The counselling on fertility preservation is of paramount importance in such cases. We report the management of a young woman with giant bilateral benign adnexal cysts, highlighting the complexity of fertility preservation in such scenario.

Relación entre ansiedad, depresión y linfocitos T CD4+ en pacientes con virus de inmunodeficiencia humana (VIH) en un hospital general de Lima* / Relationship between anxiety, depression and CD4+ T lymphocytes in patients with Human Immunodeficiency Virus (HIV) in a general hospital in Lima

RESUMEN Objetivo: Determinar la relación entre ansiedad, depresión y recuento de linfocitos T CD4+ en una muestra de personas portadoras del virus de inmunodeficiencia humana (VIH). Metodología: Estudio observacional y analítico. Se evaluó a 144 pacientes con VIH en un hospital general de Lima, Perú. Se utilizó la Escala de Ansiedad y Depresión Hospitalaria (HADS). Resultados: La edad media de los sujetos de estudio fue de 41 años. La mayoría estuvo constituida por varones (71,5 %), solteros (86,1 %) y con grado de instrucción secundaria (57,6 %). La duración promedio de la enfermedad fue 7,7 años; el 11,1 % presentó alguna comorbilidad; y el 95,1 % utilizó tenofovir como tratamiento. El 34 % y el 16,7 % presentaron algún nivel de ansiedad y depresión, respectivamente. Los pacientes que se encontraban en estadio de sida presentaron mayores niveles de ansiedad (p < 0,001) y depresión (p < 0,001). Los pacientes con VIH y comorbilidades médicas presentaron mayores niveles de depresión (p = 0,044). Los niveles de ansiedad (ρ = -0,516, p = 0,01) y depresión (ρ = -0,509; p = 0,01) estuvieron relacionados con el recuento de linfocitos T CD4+. Conclusión: Se encontraron mayores niveles de depresión en pacientes con comorbilidades y estadio de sida, así como mayores niveles de ansiedad en pacientes en estadio de sida. Se comprobó, además, una relación indirecta y significativa entre los niveles de ansiedad, depresión y el recuento de linfocitos T CD4+. Se recomienda capacitar a los profesionales de salud en el tamizaje de ansiedad y depresión, a fin de mejorar la salud mental de pacientes con VIH.

ABSTRACT Objective: To determine the relationship between anxiety, depression and CD4+ T lymphocyte count in a sample of people carrying the human immunodeficiency virus (HIV). Methodology: Observational and analytical study. A total of 144 HIV-positive patients were evaluated. The Hospital Anxiety and Depression Scale (HADS) was used. Results: The sample's mean age was 41 years. Most of the probands were male (71.5%), single (86.1%) and with secondary education (57.6%). The average length of the disease was 7.7 years, 11.1% presented some comorbidity, and 95.1% used tenofovir as treatment. Thirty-four and 16.7% presented some level of anxiety and depression, respectively. Patients at the AIDS stage presented higher levels of anxiety (p < 0.001) and depression (p < 0.001). Patients with HIV and medical comorbidities had higher levels of depression (p = 0.044). Anxiety (ρ = -0.516, p = 0.01) and depression (ρ = -0.509; p = 0.01) levels were related to CD4+ T lymphocyte count. Conclusion: Higher levels of depression were found in patients with comorbidities and AIDS stage, and higher levels of anxiety were found in patients at the AIDS stage. In addition, a significant indirect relationship was found between anxiety and depression levels and the CD4+ T cell count. Training healthcare professionals to screen for anxiety and depression in order to improve the mental health of HIV patients, is highly recommended.

Oxidized Regenerated Cellulose Versus Calcium Alginate in Controlling Bleeding From Malignant Wounds: A Randomized Controlled Trial.

BACKGROUND: There is no consensus on the best intervention for topical management of bleeding in malignant wounds. Although surgical hemostatic dressings are recommended, the use of calcium alginate (CA) is frequent among practitioners. OBJECTIVE: The aim of this study was to evaluate the hemostatic efficacy of oxidized regenerated cellulose (ORC) and CA dressing in the management of bleeding from malignant wounds resulting from breast cancer. METHODS: This was a randomized open clinical trial. The outcomes measured were total time to hemostasis and the number of hemostatic products used. RESULTS: Sixty-one patients were potentially eligible for the study, 1 did not consent, and 32 were assessed to be ineligible, resulting in a sample of 28 who were randomized to 2 study groups. Total time to hemostasis was 93.8 seconds in the ORC group, with an average of 30.1 seconds (95% confidence interval, 18.6-189 seconds), and 67 seconds in the CA group, with an average of 30.4 seconds (confidence interval, 21.7 seconds to imprecise upper limit). The main difference was 26.8 seconds. Kaplan-Meier log-rank test, and Cox model showed no statistical significance (P = 0.894). A total of 18 hemostatic products were used in the CA group and 34 in the ORC group. No adverse effects were identified. CONCLUSIONS: Although no significant differences were identified in terms of time, more hemostatic products were used in the ORC group, highlighting the effectiveness of CA. IMPLICATIONS FOR PRACTICE: Calcium alginate may be the first choice in the management of bleeding in malignant wounds, favoring nursing in the most immediate hemostatic actions.

Pharmacokinetic Alterations Associated with Critical Illness.

Haemodynamic, metabolic, and biochemical derangements in critically ill patients affect drug pharmacokinetics and pharmacodynamics making dose optimisation particularly challenging. Appropriate therapeutic dosing depends on the knowledge of the physiologic changes caused by the patient's comorbidities, underlying disease, resuscitation strategies, and polypharmacy. Critical illness will result in altered drug protein binding, ionisation, and volume of distribution; it will also decrease oral drug absorption, intestinal and hepatic metabolism, and renal clearance. In contrast, the resuscitation strategies and the use of vasoactive drugs may oppose these effects by leading to a hyperdynamic state that will increase blood flow towards the major organs including the brain, heart, kidneys, and liver, with the subsequent increase of drug hepatic metabolism and renal excretion. Metabolism is the main mechanism for drug clearance and is one of the main pharmacokinetic processes affected; it is influenced by patient-specific factors, such as comorbidities and genetics; therapeutic-specific factors, including drug characteristics and interactions; and disease-specific factors, like organ dysfunction. Moreover, organ support such as mechanical ventilation, renal replacement therapy, and extracorporeal membrane oxygenation may contribute to both inter- and intra-patient variability of drug pharmacokinetics. The combination of these competing factors makes it difficult to predict drug response in critically ill patients. Pharmacotherapy targeted to therapeutic goals and therapeutic drug monitoring is currently the best option for the safe care of the critically ill. The aim of this paper is to review the alterations in drug pharmacokinetics associated with critical illness and to summarise the available evidence.

Resultados materno y perinatal de pacientes con diagnóstico prenatal de gastrosquisis en un centro de Medellín / Maternal and perinatal outcomes of patients with prenatal diagnosis of gastroschisis in a center in Medellin

Objetivo: Describir los resultados maternos y perinatales de pacientes con diagnóstico prenatal de gastrosquisis atendidos en un centro de referencia obstétrica de Medellín. Método: Estudio observacional, descriptivo y retrospectivo, llevado a cabo en la Clínica Universitaria Bolivariana en fetos con diagnóstico prenatal de gastrosquisis desde el 1 de enero de 2010 hasta el 31 de julio de 2021. Resultados: Se identificaron 54 gestantes con diagnóstico prenatal de gastrosquisis. En el 63% era su primer embarazo y el 27,8% eran adolescentes. La duración promedio de la gestación fue de 35 semanas y 6 días. La cesárea fue la vía más común (98,1%) y la indicación más frecuente fue sufrimiento de asa 66,7%. El 55,6% de los neonatos requirieron más de una intervención quirúrgica para el cierre de la pared abdominal. Las complicaciones más frecuentes fueron anemia (66,7%) e íleo posoperatorio (72,2%). La mortalidad fue del 13%. Conclusiones: Se evidencian algunas características similares a las reportadas en otras series. La mayor presentación fue en primer embarazo, la causa de finalización de la gestación fue sufrimiento de asas (demostrando la importancia del seguimiento ecográfico), y las complicaciones más frecuentes fueron anemia e íleo posoperatorio presentados por la prematuridad. La mortalidad comparada con la de otras instituciones locales fue menor.

Objective: To describe the outcomes of maternal and perinatal in patients diagnosed with prenatal gastroschisis that received medical care at an obstetric reference center in Medellin. Method: Observational, descriptive and retrospective study in fetuses with a prenatal diagnosis of gastroschisis performed in the Clínica Universitaria Bolivariana between January 1st 2010 and July 31st 2021. Results: Were included 54 pregnant women with prenatal diagnosis of gastroschisis. The 63% were their first pregnancy and 27,8% were adolescents. The average duration of gestation was 35 weeks and 6 days. Cesarean section was the most common way of delivery (98,1%) and the most frequent indication was suffering from loop (66,7%). The 55,6% of neonates required more than one surgical intervention for closure of the abdominal wall. The most frequent complications were anemia (66,7%) and postoperative ileus (72,2%). A mortality of 13% was presented. Conclusions: Some characteristics like reported in other series are evident. The greatest presentation was in the first pregnancy, the cause of termination of pregnancy was suffering from loops (demonstrating the importance of ultrasound monitoring) and the most frequent complications were anemia and postoperative ileus presented by prematurity. Mortality, compared to other local institutions, was lower.

Prevalence of pressure injury and associated factors in hospitalized adult patients with cancer.

INTRODUCTION: Hospitalized cancer patients experience limitations in their daily activities resulting from the severity of their condition. Such changes alter patients' sensory perception and hinder their mobility, thus predisposing them to the development of PI. OBJECTIVE: The goal of this study was to analyze the prevalence of PI and associated factors in hospitalized cancer patients. MATERIALS AND METHODS: This observational, epidemiological, cross-sectional, descriptive study was carried out in the inpatient and ICU settings of an oncological hospital in São Paulo, Brazil. RESULTS: A total of 341 patients who met the inclusion criteria and agreed to participate in the study were interviewed and assessed. Data obtained in the interviews were analyzed for logistic regression analysis. Pressure injury prevalence was 10% (34 patients). The use of disposable diapers was significantly associated with the development of PI, with a 6.077 increased chance of PI in such patients in the ICU setting. In this epidemiologic study of 341 hospitalized cancer patients, the prevalence of PI was 10%. The use of disposable diapers was the only factor associated with the presence of PI after logistic regression analysis. CONCLUSION: Knowing the risk factors of this specific population was essential to implement actions and optimize indications of disposable diaper use. There is an absence of epidemiologic records due to limited publications available on the subject; creating a program to prevent PI development within the inpatient, assisted population.

Efficacy and Safety of Vamorolone vs Placebo and Prednisone Among Boys With Duchenne Muscular Dystrophy: A Randomized Clinical Trial.

Importance: Corticosteroidal anti-inflammatory drugs are widely prescribed but long-term use shows adverse effects that detract from patient quality of life. Objective: To determine if vamorolone, a structurally unique dissociative steroidal anti-inflammatory drug, is able to retain efficacy while reducing safety concerns with use in Duchenne muscular dystrophy (DMD). Design, Setting, and Participants: Randomized, double-blind, placebo- and prednisone-controlled 24-week clinical trial, conducted from June 29, 2018, to February 24, 2021, with 24 weeks of follow-up. This was a multicenter study (33 referral centers in 11 countries) and included boys 4 to younger than 7 years of age with genetically confirmed DMD not previously treated with corticosteroids. Interventions: The study included 4 groups: placebo; prednisone, 0.75 mg/kg per day; vamorolone, 2 mg/kg per day; and vamorolone, 6 mg/kg per day. Main Outcomes and Measures: Study outcomes monitored (1) efficacy, which included motor outcomes (primary: time to stand from supine velocity in the vamorolone, 6 mg/kg per day, group vs placebo; secondary: time to stand from supine velocity [vamorolone, 2 mg/kg per day], 6-minute walk distance, time to run/walk 10 m [vamorolone, 2 and 6 mg/kg per day]; exploratory: NorthStar Ambulatory Assessment, time to climb 4 stairs) and (2) safety, which included growth, bone biomarkers, and a corticotropin (ACTH)-challenge test. Results: Among the 133 boys with DMD enrolled in the study (mean [SD] age, 5.4 [0.9] years), 121 were randomly assigned to treatment groups, and 114 completed the 24-week treatment period. The trial met the primary end point for change from baseline to week 24 time to stand velocity for vamorolone, 6 mg/kg per day (least-squares mean [SE] velocity, 0.05 [0.01] m/s vs placebo -0.01 [0.01] m/s; 95% CI, 0.02-0.10; P = .002) and the first 4 sequential secondary end points: time to stand velocity, vamorolone, 2 mg/kg per day, vs placebo; 6-minute walk test, vamorolone, 6 mg/kg per day, vs placebo; 6-minute walk test, vamorolone, 2 mg/kg per day, vs placebo; and time to run/walk 10 m velocity, vamorolone, 6 mg/kg per day, vs placebo. Height percentile declined in prednisone-treated (not vamorolone-treated) participants (change from baseline [SD]: prednisone, -1.88 [8.81] percentile vs vamorolone, 6 mg/kg per day, +3.86 [6.16] percentile; P = .02). Bone turnover markers declined with prednisone but not with vamorolone. Boys with DMD at baseline showed low ACTH-stimulated cortisol and high incidence of adrenal insufficiency. All 3 treatment groups led to increased adrenal insufficiency. Conclusions and Relevance: In this pivotal randomized clinical trial, vamorolone was shown to be effective and safe in the treatment of boys with DMD over a 24-week treatment period. Vamorolone may be a safer alternative than prednisone in this disease, in which long-term corticosteroid use is the standard of care. Trial Registration: ClinicalTrials.gov Identifier: NCT03439670.

Transesophageal Echocardiography-Guided Extracorporeal Membrane Oxygenation Cannulation in COVID-19 Patients.

OBJECTIVES: A paucity of data supports the use of transesophageal echocardiography (TEE) for bedside extracorporeal membrane oxygenation (ECMO) cannulation. Concerns have been raised about performing TEEs in patients with COVID-19. The authors describe the use and safety of TEE guidance for ECMO cannulation for COVID-19. DESIGN: Single-center retrospective cohort study. SETTING: The study took place in the intensive care unit of an academic tertiary center. PARTICIPANTS: The authors included 107 patients with confirmed SARS-CoV-2 infection who underwent bedside venovenous ECMO (VV ECMO) cannulation under TEE guidance between May 2020 and June 2021. INTERVENTIONS: TEE-guided bedside VV ECMO cannulation. MEASUREMENTS: Patient characteristics, physiologic and ventilatory parameters, and echocardiographic findings were analyzed. The primary outcome was the number of successful TEE-guided bedside cannulations without complications. The secondary outcomes were cannulation complications, frequency of cannula repositioning, and TEE-related complications. MAIN RESULTS: TEE-guided cannulation was successful in 99% of the patients. Initial cannula position was adequate in all but 1 patient. Fourteen patients (13%) required cannula repositioning during ECMO support. Forty-five patients (42%) had right ventricular systolic dysfunction, and 9 (8%) had left ventricular systolic dysfunction. Twelve patients (11%) had intracardiac thrombi. One superficial arterial injury and 1 pneumothorax occurred. No pericardial tamponade, hemothorax or intraabdominal bleeding occurred in the authors' cohort. No TEE-related complications or COVID-19 infection of healthcare providers were reported during this study. CONCLUSIONS: Bedside TEE guidance for VV ECMO cannulation is safe in patients with severe respiratory failure due to COVID-19. No tamponade or hemothorax, nor TEE-related complications were observed in the authors' cohort.

The prevalence of skin lesions and associated factors in hospitalised adult patients with cancer.

OBJECTIVE: To assess the prevalence of skin lesions and evaluate the clinical and sociodemographic factors associated with their presence in hospitalised patients. METHOD: This descriptive, cross-sectional, correlational study was performed in inpatient units and intensive care units of a cancer hospital in São Paulo, Brazil, after approval by the Institutional Research Ethics Committee. Data from hospitalised adult patients with cancer were collected during physical examinations and from medical records. A Chi-squared test, univariate analysis, a logistic regression model with results expressed as odds ratio (OR) and 95% confidence intervals (CI), and Classification and Regression Tree (CART) analysis were used to evaluate the data. RESULTS: Of 341 patients, 80 had skin lesions, equating to an overall prevalence of 23.5%. The skin lesions included pressure injuries (10%), incontinence-associated dermatitis (6.7%), skin tears (6.5%), malignant wounds (3.8%) and complicated surgical wounds (3.2%). The factors associated with skin lesions in cancer patients were the use of disposable nappies (OR: 4.436) and age (59.1±15.1 years), according to the CART analysis, and the wearing of nappies (OR: 4.466, p<0.001), presence of ecchymosis (OR: 2.532, p<0.001) and infection (OR: 6.449, p=0.040), according to multiple regression analysis. CONCLUSION: This study contributed to knowledge about prevalence and associated factors of skin lesions in hospitalised patients with cancer, allowing the implementation of preventive measures.
