Published: March 2014

Objective: Assess the impact of intercurrent respiratory infections in infants <29 weeks gestational age (GA).

Study Design: A retrospective cohort study of 111 infants born <29 weeks GA, controlling for bronchopulmonary dysplasia (BPD) severity and assessing pulmonary health over the first year of life through oxygen, diuretic and inhaled steroid use.

Result: Regression analysis showed viral infections increased oxygen use (odds ratio (OR) of 15.5 (confidence interval (CI)=3.4, 71.3)). The trend test showed increasing numbers of viral infections were associated with increased oxygen (OR (95% CI)=6.4 (2.3 to 17.4), P=0.0003), diuretic (OR (95% CI)=2.4 (1.1to 5.2), P=0.02) and inhaled steroid use (OR (95% CI)=2.2 (1.003 to 5.2), P=0.049), whereas bacterial infections were not.

Conclusion: Viral infections caused more long-term pulmonary morbidity/mortality than bacterial infections on premature lung health, even when controlling for BPD.

Background: Time to deterioration (TTD) endpoints are often utilized in the analysis of patient-reported outcome (PRO) data in oncology clinical trials but different endpoint definitions and analysis frameworks exist that can impact result interpretation. This review examined the analysis, reporting and heterogeneity of TTD endpoints in the literature, the impact of analysis methods on results, and provides recommendations for future trials.

Methods: A targeted literature review of articles published between 2017 and 2022 was performed to collate TTD endpoints reported in oncology randomized controlled trials (RCTs).

Purpose: In the present study, the findings related to the epidemiology, clinical presentation, and therapeutic outcomes of elderly patients treated with transoral laser microsurgery (TOLM) and transoral robotic surgery (TORS) for supraglottic laryngeal squamous cell carcinoma (LSCC) have been reviewed.

Methods: A PubMed, Cochrane Library, and Scopus literature search was conducted according to the PRISMA statements. Critical literature analysis was carried out considering the last advancement in TOLS and TORS, and their related surgical, functional, and survival outcomes.

TANGO2 deficiency disorder, a rare autosomal recessive genetic disorder characterised by biallelic loss-of-function variants in the TANGO2 gene, was first described in 2016. This disorder involves the transport and Golgi organisation homologue, impacting Golgi membrane redistribution into the endoplasmic reticulum. Clinically, affected individuals exhibit a multiorgan phenotype, with prominent neurological manifestations such as developmental delay and regression.

Background: Patient-reported outcomes (PROs) play an increasing role in the evaluation of oncology treatments. At the same time, single-arm trials are commonly included in regulatory approval submissions. Because of the high risk of biases, results from single-arm trials require careful interpretation.

Introduction: Approximately 2 million people in Italy are currently living with dementia or mild cognitive impairment (MCI), and 4 million are involved as family members or caregivers. Considering the significant impact of dementia, the Italian Ministry of Health entrusted the Italian National Institute of Health (Istituto Superiore di Sanità) with the development of a guideline within the Italian National Guideline System (Sistema Nazionale Linee Guida, SNLG) on the diagnosis and treatment of dementia and MCI. The main objective was to provide evidence-based recommendations aimed at reducing the variability and ensuring the appropriateness of clinical practices throughout the whole care process from identification and diagnosis to the end of life for people with dementia (PwD) or MCI and their families/caregivers.
