Evaluation of nutritional status in pediatric intensive care unit patients: the results of a multicenter, prospective study in Turkey.

Introduction: Malnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies. Material and Method: In this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined. Results: Of the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48 h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48 h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024). Conclusion: Timely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48 h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score.

Health Effects of Infant Formula Supplemented with Probiotics or Synbiotics in Infants and Toddlers: Systematic Review with Network Meta-Analysis.

Supplementation of infant and follow-up formula with probiotics or synbiotics has become a common practice. In 2011 and 2017, the evidence regarding the impact of these interventions was analysed systematically. Recently new evidence was published. To evaluate through a systematic review with network meta-analysis the evidence on the impact of infant formula supplemented with probiotics or synbiotics for healthy infants and 36-month-old toddlers. RCTs published between 1999-2019 for infant formulas supplemented with probiotics alone or synbiotics in healthy infants and toddlers were identified. Data analysis included clinical (gastrointestinal symptoms, risk reduction of infectious diseases, use of antibiotics, weight/height gain and frequency of adverse events) and non-clinical outcomes (changes in faecal microbiota and immune parameters). A random effect model was used. Hedges' standard mean difference (SMD) and risk ratio (RR) were calculated. Rank analysis was performed to evaluate the superiority of each intervention. Twenty-six randomised controlled trials with 35 direct comparisons involving 1957 children receiving probiotic-supplemented formula and 1898 receiving control formula were reviewed. The mean duration of intervention was 5.6 ± 2.84 months. Certain strains demonstrated a reduction in episodes of colic, number of days with fever and use of antibiotics; however, there was considerable heterogeneity which reduced the level of certainty of effect. No significant effects were observed on weight, height or changes in faecal proportions of Bifidobacteria, Lactobacillus, Bacteroides or Clostridia. Although there is some evidence that may support a potential benefit of probiotic or synbiotic supplementation of infant formulas, variation in the quality of existing trials and the heterogeneity of the data preclude the establishment of robust recommendations.

Safety and reactogenicity of a liquid formulation of human rotavirus vaccine (porcine circovirus-free): A phase III, observer-blind, randomized, multi-country study.

BACKGROUND: The introduction of rotavirus vaccines in national immunization programs has decreased mortality and hospitalizations due to diarrhea. GSK's live-attenuated, human rotavirus vaccine (HRV) is a 2-dose vaccine for oral administration. Following the detection of porcine circovirus type 1 (PCV-1) in HRV, a PCV-free (no detection of PCV-1 and PCV-2 according to the detection limits of tests used) HRV was developed. The immunogenicity, reactogenicity and safety of a liquid (liq) PCV-free HRV were assessed in two prior studies. The present study aimed to generate additional reactogenicity and safety data. METHODS: This phase III, observer-blind, randomized, controlled multi-country study enrolled healthy 6-12-week-old infants. Infants were randomized to receive 2 doses of either the liq PCV-free HRV (N = 677) or the lyophilized (lyo) HRV (N = 674) 1-2 months apart. Solicited adverse events (AEs) were recorded for 8 days after each dose, unsolicited AEs for 31 days and serious AEs (SAEs) from dose 1 until the end of the 6-month safety follow-up. RESULTS: The occurrence of solicited general AEs was comparable between the liq PCV-free HRV and the lyo HRV groups, with irritability/fussiness being the most frequently reported (74.9% [95% confidence interval: 71.4-78.1] and 72.1% [68.6-75.5]). Unsolicited AEs were reported for 29.7% (26.3-33.3) and 30.6% (27.1-34.2) of infants in the liq PCV-free HRV and the lyo HRV group. A total of 39 and 38 infants reported at least one SAE, respectively. The most common SAEs were upper respiratory tract (0.7% and 0.9%) and urinary tract infections (0.9% and 0.6%). One SAE (constipation) in the liq PCV-free HRV group was considered as potentially causally related to vaccination by the investigator. No deaths were reported. CONCLUSIONS: The study showed that the reactogenicity and safety profiles of the liq PCV-free HRV and the lyo HRV are similar. CLINICALTRIALS: gov identifier: NCT0395474.

Clinical Presentation of Influenza in Children 6 to 35 Months of Age: Findings From a Randomized Clinical Trial of Inactivated Quadrivalent Influenza Vaccine.

BACKGROUND: In an exploratory analysis of an inactivated quadrivalent influenza vaccine (IIV4) trial in children 6-35 months without risk factors for influenza, we evaluated clinical presentation of influenza illness and vaccine impact on health outcomes. METHODS: This phase III trial was conducted in 13 geographically diverse countries across 5 influenza seasons (2011-2014). Children were randomized 1:1 to IIV4 or control. Active surveillance was performed for influenza-like episodes (ILE); influenza was confirmed by reverse transcription polymerase chain reaction (RT-PCR). The total vaccinated cohort was evaluated (N = 12,018). RESULTS: 5702 children experienced ≥1 ILE; 356 (IIV4 group) and 693 (control group) children had RT-PCR-confirmed influenza. Prevalence of ILE was similar in RT-PCR-positive and RT-PCR-negative cases regardless of vaccination. Breakthrough influenza illness was attenuated in children vaccinated with IIV4; moderate-to-severe illness was 41% less likely to be reported in the IIV4 group than the control group [crude odds ratio: 0.59 (95% confidence intervals: 0.44-0.77)]. Furthermore, fever >39°C was 46% less frequent following vaccination with IIV4 than with control [crude odds ratio: 0.54 (95% confidence intervals: 0.39-0.75)] in children with breakthrough illness. Health outcome analysis showed that, each year, IIV4 would prevent 54 influenza cases per 1000 children and 19 children would need to be vaccinated to prevent 1 new influenza case. CONCLUSIONS: In addition to preventing influenza in 50% of participants, IIV4 attenuated illness severity and disease burden in children who had a breakthrough influenza episode despite vaccination.

Mycoplasma pneumoniae infection with neurologic complications.

BACKGROUND: Extrapulmonary complications of Mycoplasma pneumoniae (M. pneumoniae) infection include encephalitis, optic neuritis, acute psychosis, stroke, cranial nerve palsies, aseptic meningitis and also it may be implicated in immune mediated neurological diseases such as acute demyelinating encephalomyelitis, Guillain-Barre syndrome and transverse myelitis. CASE PRESENTATION: We present five cases with acute neurological diseases after M. pneumoniae infection. The clinical presentations were characterized by encephalitis in 2 patients, Gullain-Barre syndrome in 2 patients, transverse myelitis in 1 patient. M. pneumoniae infection was detected in serum by serological method. Only two patients had respiratory symptoms preceding M. pneumoniae infection. Brain MRI revealed hyperintensities on corpus striatum and mesencephalon in one patient with encephalitis, the other had front parietal coalescent periventricular white matter lesions on T2 images. The patient with transverse myelitis had cervical, dorsal and lumbar scattered hyperintense lesions on T2 images. Two patients were treated with high dose steroid, the other two patients received treatment with intravenous immune globuline. CONCLUSION: M. pneumoniae may reveal different neurologic complications with different radiologic findings.

Successful treatment of tongue aspergillosis caused by Aspergillus flavus with liposomal amphotericin B in a child with acute lymphoblastic leukemia.

A 5-year-old boy with acute lymphoblastic leukemia and probable pulmonary aspergillosis developed a hard, protuberant, white-yellow and aggressive elongated lesion on the left side of his tongue during a febrile agranulocytopenic episode. Despite the use of broad-spectrum antibiotics and other supportive therapies, the lesion increased to about 2x4 cm in size within two days and became grey-black with an erythemateous, irregular line. Partial excision of the tongue was performed and isolates recovered from the tongue biopsy specimen were identified as Aspergillus flavus. An increase in the systemic dose (7 mg/kg/day) and local intraoral delivery of liposomal amphotericin B was successful in treating the patient and resulted in improved clinical and laboratory findings. Herein, we document the observation of tongue aspergillosis in a leukemic child with probable pulmonary aspergillosis receiving liposomal amphotericin B therapy and the successful treatment of tongue aspergillosis with an increased dose (7mg/kg) of liposomal amphotericin B. To the best of our knowledge, this is the youngest patient with documented intraoral aspergillosis and only the second case of tongue aspergillosis caused by Aspergillus flavus.
