Objective: To determine the risk factors for premature myocardial infarction among young South Asians. Design and setting: Case-control study in a hospital admitting unselected patients with non-fatal acute myocardial infarction. Methods and subjects: Risk factor assessment was done in 193 subjects aged 15-45 years with a first acute myocardial infarct, and in 193 age, sex, and neighbourhood matched population based controls. Results: The mean (SD) age of the subjects was 39 (4.9) years and 326 (84.5%) were male. Current smoking (odds ratio (OR) 3.82, 95% confidence interval (CI) 1.47 to 9.94), use of ghee (hydrogenated vegetable oil) in cooking (OR 3.91, 95% CI 1.52 to 10.03), raised fasting blood glucose (OR 3.32, 95% CI
BackgroundDue to the limited data available in the pediatric population and lack of interventional studies to show that administration of vitamin D indeed improves clinical outcomes, opinion is still divided as to whether it is just an innocent bystander or a marker of severe disease. Our objective was therefore to estimate the prevalence of vitamin D deficiency in children admitted to intensive care unit (ICU) and to examine its association with duration of ICU stay and other key clinical outcomes.MethodsWe prospectively enrolled children aged 1 month–17 years admitted to the ICU over a period of 8 months (n = 101). The primary objectives were to estimate the prevalence of vitamin D deficiency (serum 25 (OH) <20 ng/mL) at ‘admission’ and to examine its association with length of ICU stay.ResultsThe prevalence of vitamin D deficiency was 74 % (95 % CI: 65–88). The median (IQR) duration of ICU stay was significantly longer in ‘vitamin D deficient’ children (7 days; 2–12) than in those with ‘no vitamin D deficiency’ (3 days; 2–5; p = 0.006). On multivariable analysis, the association between length of ICU stay and vitamin D deficiency remained significant, even after adjusting for key baseline variables, diagnosis, illness severity (PIM-2), PELOD, and need for fluid boluses, ventilation, inotropes and mortality [adjusted mean difference (95 % CI): 3.5 days (0.50–6.53); p = 0.024].ConclusionsWe observed a high prevalence of vitamin D deficiency in critically ill children in our study population. Vitamin D deficient children had a longer duration of ICU stay as compared to others.Electronic supplementary materialThe online version of this article (doi:10.1186/s13613-015-0102-8) contains supplementary material, which is available to authorized users.
Children receiving fluid boluses over 5-10 minutes each had a higher risk of intubation than those receiving boluses over 15-20 minutes each. Notwithstanding the lack of difference in risk of mortality and the possibility that a lower threshold of intubation and mechanical ventilation was used in the presence of fluid overload, our results raise concerns on the current recommendation of administering boluses over 5-10 minutes each in children with septic shock.
Objectives: Energy needs in critically ill children are dynamic and variable. Data on energy balance in children with severe sepsis using indirect calorimetry (IC) is lacking. Thus, we planned to study the energy needs and balance of this cohort. Methods: Prospective observational study conducted in ventilated children aged 5 to 12 years, admitted in pediatric intensive care unit with severe sepsis from May 2016 to June 2017. Measured resting energy expenditure (mREE) was measured with IC (Quark RMR, COSMED) till 7 days or pediatric intensive care unit discharge. Predicted energy expenditure (pREE) was estimated using Schofield, Harris and Benedict, and FAO/WHO/UNU equations. Primary outcome was to study the daily energy balance. Secondary outcome was to determine nitrogen balance and agreement of mREE with pREE. Results: Forty children (24 boys) with median age of 7 (5.2, 10) years were enrolled. All received enteral nutrition; 35 (87.5%) received inotropic support. Median ventilation-free days were 19 days and 4 children died (10%). A total of 176 IC measurements were obtained with an average of 4 per patient. The mean mREE was 51 ± 17 kcal/kg and mean respiratory quotient was 0.77 ± 0.07. There was persistent negative energy balance from days 1 to 7 and negative nitrogen balance from days 1 to 5. There was poor agreement of pREE with mREE using Bland Altman plots. None of severity of illness scores (PRISM III, daily Sequential Organ Function Assessment, daily Vasoactive Inotropic Score) showed correlation with mREE. Conclusions: Persistent negative energy and nitrogen balance exist during acute phase of severe sepsis. Predictive equations are inaccurate compared with IC as the criterion standard.
The prevalence of severe vitamin D deficiency is high in children with septic shock admitted to pediatric intensive care unit. Severe vitamin D deficiency at admission seems to be associated with lower rates of shock reversal at 24 hours of ICU stay. Our study provides preliminary data for planning interventional studies in children with septic shock and severe vitamin D deficiency.
OBJECTIVE: To determine if initial fluid resuscitation with balanced crystalloid (e.g., multiple electrolytes solution [MES]) or 0.9% saline adversely affects kidney function in children with septic shock. DESIGN: Parallel-group, blinded multicenter trial. SETTING: PICUs of four tertiary care centers in India from 2017 to 2020. PATIENTS: Children up to 15 years of age with septic shock. METHODS: Children were randomized to receive fluid boluses of either MES (PlasmaLyte A) or 0.9% saline at the time of identification of shock. All children were managed as per standard protocols and monitored until discharge/death. The primary outcome was new and/or progressive acute kidney injury (AKI), at any time within the first 7 days of fluid resuscitation. Key secondary outcomes included hyperchloremia, any adverse event (AE), at 24, 48, and 72 hours, and all-cause ICU mortality. INTERVENTIONS: MES solution (n = 351) versus 0.9% saline (n = 357) for bolus fluid resuscitation during the first 7 days. MEASUREMENTS AND MAIN RESULTS: The median age was 5 years (interquartile range, 1.3–9); 302 (43%) were girls. The relative risk (RR) for meeting the criteria for new and/or progressive AKI was 0.62 (95% CI, 0.49–0.80; p < 0.001), favoring the MES (21%) versus the saline (33%) group. The proportions of children with hyperchloremia were lower in the MES versus the saline group at 24, 48, and 72 hours. There was no difference in the ICU mortality (33% in the MES vs 34% in the saline group). There was no difference with regard to infusion-related AEs such as fever, thrombophlebitis, or fluid overload between the groups. CONCLUSIONS: Among children presenting with septic shock, fluid resuscitation with MES (balanced crystalloid) as compared with 0.9% saline resulted in a significantly lower incidence of new and/or progressive AKI during the first 7 days of hospitalization.
Oxygen is an essential lifesaving medicine used for several indications at all levels of health care. The COVID-19 pandemic and its recent second wave have resulted in a surge in demand for necessary resources, including trained staff, hospital beds, and medical supplies like oxygen. Limited availability of these resources resulted in added risk of adverse outcomes. Also, the widespread unregulated use of oxygen by the general public in household settings poses safety concerns. This review focuses on sources of medical oxygen like cryogenic oxygen plants, pressure swing adsorption, oxygen concentrators, and oxygen cylinders. Their specifications, storage, distribution within healthcare settings, regulation, and safety concerns have been considered. Resources needed for calculating oxygen demand, surge planning, identifying the suitable source, and distribution systems for different settings have been detailed. This review aims to help the hospital administrators, biomedical engineers, and clinicians plan and rationalize oxygen usage in low-and middle-income countries during the COVID-19 pandemic.
Hypoparathyroidism leading to status dystonicus is rarely reported in literature. The authors present an 8-y-old girl with idiopathic familial hypoparathyroidism who presented with status dystonicus. She was managed successfully with midazolam infusion, calcium and vitamin D supplementation, and oral anti-dystonia drugs.
