RESUMO

OBJECTIVE: Dipeptidase-1 (DPEP-1) is a recently discovered leucocyte adhesion receptor for neutrophils and monocytes in the lungs and kidneys and serves as a potential therapeutic target to attenuate inflammation in moderate-to-severe COVID-19. We aimed to evaluate the safety and efficacy of the DPEP-1 inhibitor, LSALT peptide, to prevent specific organ dysfunction in patients hospitalised with COVID-19. DESIGN: Phase 2a randomised, placebo-controlled, double-blinded, trial. SETTING: Hospitals in Canada, Turkey and the USA. PARTICIPANTS: A total of 61 subjects with moderate-to-severe COVID-19. INTERVENTIONS: Randomisation to LSALT peptide 5 mg intravenously daily or placebo for up to 14 days. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary endpoint was the proportion of subjects alive and free of respiratory failure and/or the need for renal replacement therapy (RRT). Numerous secondary and exploratory endpoints were assessed including ventilation-free days, and changes in kidney function or serum biomarkers. RESULTS: At 28 days, 27 (90.3%) and 28 (93.3%) of subjects in the placebo and LSALT groups were free of respiratory failure and the need for RRT (p=0.86). On days 14 and 28, the number of patients still requiring more intensive respiratory support (O2 ≥6 L/minute, non-invasive or invasive mechanical ventilation or extracorporeal membrane oxygenation) was 6 (19.4%) and 3 (9.7%) in the placebo group versus 2 (6.7%) and 2 (6.7%) in the LSALT group, respectively (p=0.14; p=0.67). Unadjusted analysis of ventilation-free days demonstrated 22.8 days for the LSALT group compared with 20.9 in the placebo group (p=0.4). LSALT-treated subjects had a significant reduction in the fold expression from baseline to end of treatment of serum CXCL10 compared with placebo (p=0.02). Treatment-emergent adverse events were similar between groups. CONCLUSION: In a Phase 2 study, LSALT peptide was demonstrated to be safe and tolerated in patients hospitalised with moderate-to-severe COVID-19. TRIAL REGISTRATION NUMBER: NCT04402957.

RESUMO

OBJECTIVES: Current evidence favors plasma to be effective against coronavirus disease 2019 (COVID-19) in critically ill patients in the early stages of infection. We investigated the safety and efficacy of convalescent plasma in specifically late-stage (designated as after 2 weeks of hospital admission) severe COVID-19 infection. We also conducted a literature review on the late-stage use of plasma in COVID-19. METHODS: This case series examined eight COVID-19 patients admitted to the intensive care unit (ICU) who met criteria for severe or life-threatening complications. Each patient received one dose (200 mL) of plasma. Clinical information was gathered in intervals of 1 day pretransfusion and 1 hour, 3 days, and 7 days posttransfusion. The primary outcome was effectiveness of plasma transfusion, measured by clinical improvement, laboratory parameters, and all-cause mortality. RESULTS: Eight ICU patients received plasma late in the course of COVID-19 infection, on average at 16.13 days postadmission. On the day before transfusion, the averaged initial Sequential Organ Failure Assessment (SOFA) score, PaO2:FiO2 ratio, Glasgow Coma Scale (GCS), and lymphocyte count were 6.5, 228.03, 8.63, and 1.19, respectively. Three days after plasma treatment, the group averages for the SOFA score (4.86), PaO2:FiO2 ratio (302.73), GCS (9.29), and lymphocyte count (1.75) improved. Although the mean GCS improved to 10.14 by posttransfusion day 7, the other means marginally worsened with an SOFA score of 5.43, a PaO2:FiO2 ratio of 280.44, and a lymphocyte count of 1.71. Clinical improvement was noted in six patients who were discharged from the ICU. CONCLUSIONS: This case series provides evidence that convalescent plasma may be safe and effective in late-stage, severe COVID-19 infection. Results showed clinical improvement posttransfusion as well as decreased all-cause mortality in comparison to pretransfusion predicted mortality. Randomized controlled trials are needed to conclusively determine benefits, dosage, and timing of treatment.

RESUMO

Intracranial lipomas are rare incidental lesions. Rokitansky first described a corpus callosal lipoma on the posterior part of the corpus callosum in 1856. Since then many cases have been reported. We report the imaging findings of an interhemispheric lipoma extending into subcutaneous plane associated with spinal lipomeningocele and corpus callosal dysgenesis. Computed tomography and magnetic resonance imaging findings are characteristic. All cases have been reported in pediatric age group till now. Such a case in this age group has not been reported earlier.

RESUMO

Embryologically mullerian duct derivatives lead to formation of female genitalia and wolffian duct derivatives to male genitalia. Presence of mullerian duct derivatives in a chromosomally normal male (XY) leads to male pseudohermaphroditism and is referred to as Persistent Mullerian Duct Syndrome (PMDS). A young male patient with bilateral cryptorchidism presented to our hospital who was subsequently imaged. There are many case reports of persistent mullerian duct syndrome but they focus mainly on surgical aspects. In this article, MRI features of persistent müllerian duct syndrome are presented.

RESUMO

The American Heart Association reports the annual incidence of out-of-hospital cardiopulmonary arrests (OHCA) is greater than 300,000 with a survival rate of 9.5%. Bystander cardiopulmonary resuscitation (CPR) saves one life for every 30, with a 10% decrease in survival associated with every minute of delay in CPR initiation. Bystander CPR and training vary widely by region. We conducted a retrospective study of 320 persons who suffered OHCA in South Florida over 25 months. Increased survival, overall and with bystander CPR, was seen with increasing income (p = 0.05), with a stronger disparity between low- and high-income neighborhoods (p = 0.01 and p = 0.03, resp.). Survival with bystander CPR was statistically greater in white- versus black-predominant neighborhoods (p = 0.04). Increased survival, overall and with bystander CPR, was seen with high- versus low-education neighborhoods (p = 0.03). Neighborhoods with more high school age persons displayed the lowest survival. We discovered a significant disparity in OHCA survival within neighborhoods of low-income, black-predominance, and low-education. Reduced survival was seen in neighborhoods with larger populations of high school students. This group is a potential target for training, and instruction can conceivably change survival outcomes in these neighborhoods, closing the gap, thus improving survival for all.

RESUMO

BACKGROUND: Health care in prisons is one of the neglected health areas in our country. Looking into the health problems of prisons will show us a way for the approach in providing the heath care for prisoners. OBJECTIVES: To assess the health status of convicted inmates of prison and to study their sociodemographic profile. MATERIALS AND METHODS: A cross-sectional study was conducted among the inmates of central prison over a period of 1 year. Study population comprised of 300 convicted life-term prisoners. The inmates were interviewed using predesigned and pretested proforma. Sociodemographic data were analyzed by frequencies and percentages along with 95% confidence interval using statistical package SPSS18. RESULTS: In health status, 29 (9.6%) inmates suffered from acute upper respiratory tract infections and 15 (5%) from acute lower respiratory tract infections. A total of 54 (18%) inmates had ascariasis. Diseases of musculoskeletal system and connective tissue contributed to 26 (8.7%) of inmates. A total of 252 (84%) prisoners had anemia. In sociodemographic profile, it was found that rural people, unmarried, illiterates, lower socioeconomic status people were more likely to have committed the crime resulting in the conviction for life. CONCLUSIONS: As there is an increase in number of prisoners and morbidities among them, there is an urgent need for prison health care services in developing countries like India and provide training to the health care providers to manage the commonly existing health problems among prisoners in the prisons.

RESUMO

Inhaled glucocorticosteroids (corticosteroids) continue to be the standard treatment for nonexacerbated asthma because of their anti-inflammatory actions. These include effects on the airway vasculature, which participates in the inflammatory process. Corticosteroids are now known to have genomic as well as nongenomic effects that involve different mechanisms of action. The genomic vascular effects of inhaled corticosteroids include a decrease in airway wall hypervascularity (inhibition of angiogenesis), reversal of the increased airway blood flow, and inhibition of vascular hyperpermeability and leukocyte recruitment. In addition, inhaled corticosteroids decrease airway blood flow acutely (within minutes) and reversibly through a nongenomic action that involves noradrenergic neurotransmission. This effect is likely related to the binding of inhaled corticosteroids to the plasma membrane of and the inhibition of the extraneuronal monoamine transporter on airway vascular smooth muscle cells, thereby increasing norepinephrine concentrations at alpha(1)-adrenoceptors and causing airway vascular smooth muscle contraction and a decrease in airway blood flow. Inasmuch as vascular hyperperfusion is a manifestation of airway inflammation, the acute vasoconstriction could also be considered an anti-inflammatory effect of inhaled corticosteroids.
