Age Distribution of Cases of 2009 (H1N1) Pandemic Influenza in Comparison with Seasonal Influenza
INTRODUCTION: Several aspects of the epidemiology of 2009 (H1N1) pandemic influenza have not been accurately determined. We sought to study whether the age distribution of cases differs in comparison with seasonal influenza. METHODS: We searched for official, publicly available data through the internet from different countries worldwide on the age distribution of cases of influenza during the 2009 (H1N1) pandemic influenza period and most recent seasonal influenza periods. Data had to be recorded through the same surveillance system for both compared periods. RESULTS: For 2009 pandemic influenza versus recent influenza seasons, in USA, visits for influenza-like illness to sentinel providers were more likely to involve the age groups of 5-24, 25-64 and 0-4 years compared with the reference group of >64 years [odds ratio (OR) (95% confidence interval (CI)): 2.43 (2.39-2.47), 1.66 (1.64-1.69), and 1.51 (1.48-1.54), respectively]. Pediatric deaths were less likely in the age groups of 2-4 and <2 years than the reference group of 5-17 years [OR (95% CI): 0.46 (0.25-0.85) and 0.49 (0.30-0.81), respectively]. In Australia, notifications for laboratory-confirmed influenza were more likely in the age groups of 10-19, 5-9, 20-44, 45-64 and 0-4 years than the reference group of >65 years [OR (95% CI): 7.19 (6.67-7.75), 5.33 (4.90-5.79), 5.04 (4.70-5.41), 3.12 (2.89-3.36) and 1.89 (1.75-2.05), respectively]. In New Zealand, consultations for influenza-like illness by sentinel providers were more likely in the age groups of <1, 1-4, 35-49, 5-19, 20-34 and 50-64 years than the reference group of >65 years [OR (95% CI): 2.38 (1.74-3.26), 1.99 (1.62-2.45), 1.57 (1.30-1.89), 1.57 (1.30-1.88), 1.40 (1.17-1.69) and 1.39 (1.14-1.70), respectively]. CONCLUSIONS: The greatest increase in influenza cases during 2009 (H1N1) pandemic influenza period, in comparison with most recent seasonal influenza periods, was seen for school-aged children, adolescents, and younger adults
Bullying and Suicidality in Children and Adolescents Without Predisposing Factors: A Systematic Review and Meta-analysis
Published evidence has suggested that engaging in school or cyber bullying may potentially be associated with a suicidal ideation and suicide attempts. The aim of our review/meta-analysis was to evaluate the potential association between school and cyber bullying and suicidality (including suicidal ideation, planning and/or committing a suicide attempt) in children and adolescents (< 19 years old) who are considered as a “healthy” population, without predispositions for suicidality factors (not subpopulations with characteristics that may constitute proneness to bullying and its consequences, including sexual minorities, drug users and youth with psychiatric comorbidity). Regarding school bullying, victims and bullies independently, and victims and bullies together, were significantly more likely to present suicidal ideation and commit a suicide attempt, compared to non-involved participants. Victims of school bullying were found to be significantly more likely to commit a suicide attempt that required medical treatment. Victims of cyber bullying were significantly more likely to present suicidal ideation and commit a suicide attempt. A positive relationship between involvement in both school bullying and cyber-bullying with suicidal ideation and suicidal behavior was observed. This review/meta-analysis contributes to further understanding bullying and suicidality as it includes results of participants without any predisposing factors for suicidality, thus providing more clear results with regard to the magnitude of the effects of both school and cyber bullying on suicidality. © 2018, Springer International Publishing AG, part of Springer Nature
Early switch to oral versus intravenous antimicrobial treatment for hospitalized patients with acute pyelonephritis: a systematic review of randomized controlled trials
Background: Acute pyelonephritis is a common infection with significant
morbidity and mortality, particularly in pediatric populations.
Early-switch strategies (from intravenous to oral treatment) may be an
acceptable or even preferred option in the treatment of patients with
acute pyelonephritis in terms of effectiveness and safety and can also
reduce the economical burden associated with pyelonephritis.
Objective: We sought to evaluate the effectiveness and safety of
early-switch strategies in hospitalized patients with acute
uncomplicated pyelonephritis.
Methods: We searched in PubMed, Cochrane Central Register of Controlled
Trials, and Scopus to identify randomized controlled trials (RCTs) that
compared intravenous antibiotic regimens to regimens including an early
switch to oral (after initial intravenous) treatment.
Results: Eight RCTs (6 in children) were eligible for inclusion. In 5
RCTs the intravenous antibiotic treatment arms were not switched to oral
treatment until the end of the study while in the remaining 3 RCTs the
intravenous arms were switched late to oral treatment (after 5-10 days).
Data regarding the incidence of renal scars, microbiological
eradication, clinical cure, reinfection, persistence of acute
pyelonephritis, and adverse events were provided in 4 (all pediatric
trials), 6 (4 pediatric), 4 (2 pediatric), 5 (3 pediatric), 3 (1
pediatric), and 5 RCTs (3 pediatric), respectively. There were no
differences regarding the above outcomes between the two compared
treatment regimens in either pediatric or adult populations.
Conclusion: Early switch to oral antibiotic strategies seem to be as
effective and safe as intravenous regimens for the treatment of
hospitalized patients with acute pyelonephritis. These findings suggest
that there is probably a potential to decrease the duration of
intravenous treatment by 4-11 days in hospitalized patients with acute
pyelonephritis without compromising their outcomes
Liposomal amphotericin B in critically ill paediatric patients
What is known and Objective: Literature provides much evidence regarding liposomal amphotericin B treatment for fungal infections in neonates and infants. Relevant data regarding critically ill paediatric patients of older age are scarce. We aimed to present our experience regarding liposomal amphotericin B use in critically ill paediatric patients from a tertiary-care paediatric hospital in Athens, Greece. Methods: We prospectively identified all paediatric patients who received treatment with liposomal amphotericin B in the intensive care unit of a tertiary-care paediatric hospital during a 3-year period (2005-2008). Data were retrieved from the evaluation of the available medical records. Results and Discussion: Twenty-three (nine females, mean age: 26.4 months, range: 5-39 months) critically ill paediatric patients were included; 12 had malignancy. In 16 of the 23 included children, liposomal amphotericin B was administered for the treatment of confirmed fungal infections (all but one were invasive), whereas in seven patients, it was used as pre-emptive treatment. One patient received voriconazole concomitantly. Eleven of the 16 children with documented infections were cured; five improved. Six of the seven children who received pre-emptive treatment also showed clinical improvement. Nine deaths were noted, all attributed to underlying diseases. Two cases of hepatotoxicity and one case of nephrotoxicity (all leading to drug-discontinuation) occurred. Seven and five cases of mild reversible hypokalaemia and hyponatraemia, respectively, were also noted. What is new and Conclusion: According to the findings of our small case series, liposomal amphotericin B may provide a useful treatment option for fungal infections of vulnerable critically ill paediatric patients with considerable comorbidity. © 2011 Blackwell Publishing Ltd
Patients included in randomised controlled trials do not represent those seen in clinical practice: focus on antimicrobial agents
Clinicians rely on the findings of randomised controlled trials (RCTs)
to formulate clinical decisions regarding individual patients. We
examined whether patients included in RCTs focusing on antimicrobial
agents are representative of those encountered in real-life clinical
situations. PubMed was searched for RCTs referring to the field of
infectious diseases. Data regarding the exclusion criteria of the
identified RCTs were extracted and critically evaluated. In total, 30
trials (17 referring to respiratory tract, 5 to skin and soft-tissue, 4
to intra-abdominal, 2 to gynaecological and 2 to bloodstream infections)
were included in the study. All retrieved RCTs reported extensive
exclusion criteria. After comparing in a qualitative manner (based on
our clinical experience) the eligible patient population in the
identified RCTs with the respective population that would be encountered
in general practice, it was observed that the above-mentioned patient
populations differ considerably. In conclusion, RCTs in the field of
infectious diseases use extensive and stringent exclusion criteria, a
fact that may lead to considerable difference between the patient
populations of RCTs and those viewed in clinical practice. The
application of the findings of RCTs to the care of individual patients
should be performed cautiously. (C) 2010 Elsevier B.V. and the
