Dietary Intervention during Weaning and Development of Food Allergy: What Is the State of the Art?

Food allergy (FA) affects approximately 6-8% of children worldwide causing a significant impact on the quality of life of children and their families. In past years, the possible role of weaning in the development of FA has been studied. According to recent studies, this is still controversial and influenced by several factors, such as the type of food, the age at food introduction and family history. In this narrative review, we aimed to collect the most recent evidence about weaning and its role in FA development, organizing the gathered data based on both the type of study and the food. As shown in most of the studies included in this review, early food introduction did not show a potential protective role against FA development, and we conclude that further evidence is needed from future clinical trials.

Percutaneous cholecystostomy in elderly patients with acute cholecystitis: a systematic review and meta-analysis.

Percutaneous cholecystostomy (PC) is often preferred over early cholecystectomy (EC) for elderly patients presenting with acute cholecystitis (AC). However, there is a lack of solid data on this issue. Following the PRISMA guidelines, we searched the Medline and Web of Science databases for reports published before December 2022. Studies that assessed elderly patients (aged 65 years and older) with AC treated using PC, in comparison with those treated with EC, were included. Outcomes analyzed were perioperative outcomes and readmissions. The literature search yielded 3279 records, from which 7 papers (1208 patients) met the inclusion criteria. No clinical trials were identified. Patients undergoing PC comprised a higher percentage of cases with ASA III or IV status (OR 3.49, 95%CI 1.59-7.69, p = 0.009) and individuals with moderate to severe AC (OR 1.78, 95%CI 1.00-3.16, p = 0.05). No significant differences were observed in terms of mortality and morbidity. However, patients in the PC groups exhibited a higher rate of readmissions (OR 3.77, 95%CI 2.35-6.05, p < 0.001) and a greater incidence of persistent or recurrent gallstone disease (OR 12.60, 95%CI 3.09-51.38, p < 0.001). Elderly patients selected for PC, displayed greater frailty and more severe AC, but did not exhibit increased post-interventional morbidity and mortality compared to those undergoing EC. Despite their inferior life expectancy, they still presented a greater likelihood of persistent or recurrent disease compared to the control group.
