Standalone Ayurvedic treatment of high-risk COVID-19 patients with multiple co-morbidities: A case series.

We report a case-series of Ayurvedic treatment in seven COVID-19 positive patients with multiple co-morbidities, categorized as high-risk for poor outcome from SARS-CoV-2 infection. All of them recovered completely from their illness with resolution of symptoms following Ayurvedic treatment. The data was collected from patients treated during the early months of the COVID-19 pandemic (June 2020 to September 2020) at an out-patient Ayurvedic Clinic, Chennai, India.

Developmental Regulation of Effector and Resident Memory T Cell Generation during Pediatric Viral Respiratory Tract Infection.

Viral respiratory tract infections (VRTI) remain a leading cause of morbidity and mortality among infants and young children. In mice, optimal protection to VRTI is mediated by recruitment of effector T cells to the lungs and respiratory tract, and subsequent establishment of tissue resident memory T cells (Trm), which provide long-term protection. These critical processes of T cell recruitment to the respiratory tract, their role in disease pathogenesis, and establishment of local protective immunity remain undefined in pediatric VRTI.

Pediatric acute respiratory distress syndrome associated with human metapneumovirus and respiratory syncytial virus.

Objectives: To study the incidence, risk factors, clinical course, and outcome of ARDS in children with HMP and RSV.

Working Hypothesis: We hypothesized that ARDS in children with HMP was similar in incidence, risk factors, clinical course, and outcomes to ARDS in children with RSV.

Study Design: Retrospective, observational study over 2 years.

Airway CD8(+) T Cells Are Associated with Lung Injury during Infant Viral Respiratory Tract Infection.

Infants and young children are disproportionately susceptible to severe complications from respiratory viruses, although the underlying mechanisms remain unknown. Recent studies show that the T cell response in the lung is important for protective responses to respiratory infections, although details on the infant/pediatric respiratory immune response remain sparse. The objectives of the present study were to characterize the local versus systemic immune response in infants and young children with respiratory failure from viral respiratory tract infections and its association to disease severity.

Vitamin B deficiencies in a critically ill autistic child with a restricted diet.

An 11-year-old male with autism became less responsive and was hospitalized with hepatomegaly and liver dysfunction, as well as severe lactic acidosis. His diet for several years was self-limited exclusively to a single "fast food"-a particular type of fried chicken-and was deficient in multiple micronutrients, including the B vitamins thiamine and pyridoxine. Lactic acidosis improved rapidly with thiamine; 2 weeks later, status epilepticus-with low serum pyridoxine-resolved rapidly with pyridoxine.

Severe hemorrhagic coagulopathy with hemophagocytic lymphohistiocytosis secondary to Epstein-Barr virus-associated T-cell lymphoproliferative disorder.

Objective: We describe the coagulopathy and hemorrhagic complications associated with fulminant, secondary hemophagocytic lymphohistiocytosis in a cohort of patients with Epstein-Barr virus-associated T-cell lymphoproliferative disorder.

Patients And Methods: Institutional Review Board-approved retrospective review of all patients at our children's hospital over 3 years (2008-2010) with hemophagocytic lymphohistiocytosis secondary to acute Epstein-Barr virus-associated T-cell lymphoproliferative disorder.

Results: Four males (2, 3, 17, and 20 yr old) presented with fever, hepatosplenomegaly, and pancytopenia with elevated serum ferritin, and all met clinical and laboratory criteria for secondary hemophagocytic lymphohistiocytosis.

Nitric oxide-associated pulmonary edema in children with pulmonary venous hypertension.

Nitric oxide (NO)-associated pulmonary edema is rarely reported in children; in adults, it is often associated with left-sided heart failure. We report a case series of children with NO-associated pulmonary edema, which was defined as new multilobar alveolar infiltrates and worsening hypoxemia within 24 h of initiation or escalation of NO and radiologic or clinical improvement after NO discontinuation. We identified six patients (0.

Out-of-hospital noninvasive ventilation: epidemiology, technology and equipment.

Noninvasive ventilation has been utilized successfully in the pre- and out-of-hospital settings for a variety of disorders, including respiratory distress syndrome in neonates, neurologic and pulmonary diseases in infants and children, and heart failure as well as chronic obstructive pulmonary disease in adults. A variety of interfaces as well as mechanical positive pressure devices have been used: simple continuous positive airway pressure devices are available which do not require sophisticated equipment, while a broad spectrum of ventilators have been used to provide bilevel positive airway pressure. Extensive training of transport teams may be important, particularly when utilizing bilevel positive airway pressure in infants and children.

Comparing the clinical severity of the first versus second wave of 2009 Influenza A (H1N1) in a New York City pediatric healthcare facility.

Objective: We previously reported the epidemiology of 2009 Influenza A (H1N1) in our pediatric healthcare facility in New York City during the first wave of illness (May-July 2009). We hypothesized that compared with the first wave, the second wave would be characterized by increased severity of illness and mortality.

Design: : Case series conducted from May 2009 to April 2010.

Novel role for aldose reductase in mediating acute inflammatory responses in the lung.

Exaggerated inflammatory responses and the resultant increases in alveolar-capillary permeability underlie the pathogenesis of acute lung injury during sepsis. This study examined the functions of aldose reductase (AR) in mediating acute lung inflammation. Transgenic mice expressing human AR (ARTg) were used to study the functions of AR since mice have low intrinsic AR activity.

Plasma thrombin activatable fibrinolysis inhibitor and tissue factor pathway inhibitor changes following sepsis.

Sepsis-induced systemic inflammation results in coagulation abnormalities that may be different in gram-positive and gram-negative infections. We used ciprofloxacin to induce a predominantly gram-positive Enterococcus faecalis polymicrobial sepsis in rats. Ciprofloxacin-untreated rats exhibited a predominantly gram-negative polymicrobial sepsis.

Albuterol-induced myocardial ischemia in sickle cell anemia after hemolysis from ceftriaxone administration.

Hemolysis induced by ceftriaxone is a complication that has been described in sickle cell anemia. Albuterol is known to induce myocardial ischemia. We describe a case of albuterol-induced cardiac dysfunction in a patient with sickle cell anemia who developed severe anemia after administration of ceftriaxone.

Exacerbation of intestinal permeability in rats after a two-hit injury: burn and Enterococcus faecalis infection.

Objective: To determine alterations in intestinal epithelial permeability to solutes in burn injured rats with and without Enterococcus faecalis infection and the role of neutrophils in the intestinal permeability changes.

Design: Prospective sham-controlled animal study.

Setting: University research laboratory.

Tissue factor pathway inhibitor and thrombin activatable fibrinolytic inhibitor plasma levels following burn and septic injuries in rats.

Burn and septic injuries induce profound changes in coagulation status. This study examined the changes in plasma tissue factor pathway inhibitor (TFPI) and thrombin activatable fibrinolytic inhibitor (TAFI) levels in a rat model of burn and septic injuries. Rats underwent 30% TBSA cutaneous scald burn injury and septic insult was induced by caecal ligation and puncture (CLP).

Effects of pentoxyfylline on mesenteric lymph node T-cells in a rat model of thermal injury.

Cutaneous burn injury-induced T lymphocyte suppression is a well-known phenomenon. In this study, we evaluated the effect of treatment of burn rats with pentoxifylline (PTX) on the burn-induced suppression of T lymphocytes. Anesthetized rats were subjected to 30% total body surface area burn by exposing skin to 95 degrees C water for 10 s.

LPS-induced changes in myocardial markers in neonatal rats.

Lipopolysaccharide (LPS) produces varied systemic metabolic effects. We studied the effects of LPS on the cardiac fatty acid profile and its relationship to energy metabolism and inflammatory mediators that included TNF-alpha and nitric oxide synthase (NOS) in 10-day-old neonatal rat pups. Rat pups received an i.

T-cell proliferative responses following sepsis in neonatal rats.

Both experimental and clinical evidence suggest a suppression of T-cell function in burn and sepsis. The objective of the present study was to evaluate splenocyte and purified T-cell proliferative response and IL-2 production in septic neonatal rats. We also examined if alterations in T-cell proliferation and IL-2 production in neonatal sepsis is due to elevation in PGE2.
