Linking factors to incisional hernia following pancreatic surgery: a 14-year retrospective analysis.

BACKGROUND: Incisional hernias (IH) are a significant postoperative complication with profound implications for patient morbidity and healthcare costs. The relationship between IH and perioperative factors in pancreatic surgery, with particular attention to preoperative biliary stents and pancreatic fistulas requires further exploration. METHODS: This retrospective observational study examined adult patients who underwent open pancreatic surgeries via midline incision at a high-volume tertiary hepatopancreatobiliary center from January 2008 to December 2021. The study focused on IH incidence and associated risk factors, with particular attention to preoperative biliary stents and pancreatic fistulas. RESULTS: In a cohort of 620 individuals undergoing pancreatic surgery, 351 had open surgery with at least one-year follow-up. Within a median follow-up of 794 days (IQR 1694-537), the overall incidence of IH was 17.38%. The highest frequency of IH was observed among patients who had a Pancreaticoduodenectomy (PD). Significant predictors for the development of IH within the entire study population in a multivariable analysis included perioperative biliary stenting (OR 2.05; 95% CI 1.06-3.96; p = 0.03), increased age at diagnosis (OR 2.05; 95% CI 1.06-3.96; p = 0.01), and BMI (OR 1.08; 95% CI 1.01-1.15; p = 0.01). In the subset of patients who underwent Pancreaticoduodenectomy (PD), although the presence of biliary stents was associated with a heightened occurrence of SSIs, it did not demonstrate a direct correlation with an increased incidence of incisional hernias (IH). The development of pancreatic fistulas did not show a significant correlation with IH in either the Distal Pancreatectomy with Splenectomy (DPS) or the PD patient groups. CONCLUSIONS: The study underscores a notable association between biliary stent placement and increased IH risk after PD, mediated by elevated SSI incidence. Pancreatic fistulas were not directly correlated with IH in the studied cohorts. Further research is necessary to validate these findings and guide clinical practice.

Unraveling the connection: Uveitis prevalence and risk factors in psoriasis patients - a population-based study.

The association between uveitis and spondyloarthropathy (SpA)-related conditions is well-established. However, evidence describing the link between uveitis and psoriasis, and psoriasis without concomitant SpA-related conditions is scarce and conflicting. This large-scale population-based study sought to describe the prevalence and features of uveitis among psoriasis patients in Israel as well as investigating the risk for uveitis in different subgroups of psoriasis patients compared to the general population. We conducted a retrospective study utilizing the electronic database of the Meuhedet Health Maintenance Organization. The study included all patients diagnosed with psoriasis between 2000 and 2020, each patient was matched with four controls based on age, sex, place of residence, and index date. Logistic regression models were employed to assess the association between psoriasis and uveitis while adjusting for the presence of SpA-related conditions. A total of 61 003 psoriasis patients and 244 012 matched controls were included. The prevalence of uveitis was 1.3% versus 1.1% respectively (OR 1.12; 95% CI 1.10-1.30; p < 0.001). When adjusting to psoriasis severity, concurrent SpA, and psoriasis treatment no significant association was found. The rates of uveitis among psoriasis patients with concurrent SpA-related conditions was 3.2% compared to 1.4% in controls without psoriasis or SpA (OR 2.38; 95% CI 2.00-2.83; p < 0.001), while in psoriasis patients without SpA, the rate of uveitis was 1.0% and was similar to controls. Although crude rates of uveitis were higher in patients with severe psoriasis compared to mild psoriasis (2.1% vs. 1.1%), after adjustment, no significant association compared to controls was found in either group. Our findings suggest that the positive association between psoriasis and uveitis is primarily mediated by the coexistence of other SpA-related conditions. These findings imply the presence of a shared pathogenetic mechanism and set the direction for a phenotypic-targeted screening strategy.

The risk of serious bacterial infections among young ex-premature infants with fever.

Background and Objectives: To determine the rate of serious-bacterial-infections (SBI) in young ex-premature infants with fever, and to develop a risk-stratification algorithm for these patients. Methods: A retrospective cohort study including all infants who presented to the pediatric emergency department (ED) of a tertiary-care university-hospital between 2010 and 2020 with fever (≥38°C), were born prematurely (<37-weeks), had post-conception age of <52-weeks, and had available blood, urine, or CSF cultures. The rates of SBI by age-of-birth and age-at-visit were calculated and compared to a cohort of matched full-term controls. Results: The study included a total of 290 ex-premature cases and 290 full-term controls. There were 11 cases (3.8%) with an invasive bacterial infection (IBI) of either bacteremia, meningitis or both and only six controls (2.1%) with IBI (p = 0.32). Over 28-days chronologic-age, there were 10 (3.6%) IBIs among cases and no IBIs among the controls (p = 0.02). There were eight (3%) cases and three (1%) controls with IBI who were well-appearing on physical examination (p = 0.19). All eight well-appearing ex-premature infants were under 60-days adjusted-age, seven of whom (88%) were also under 28-days adjusted-age. There were 28 (10.6%) cases and 34 (12%) controls with urinary tract infection (UTI) (p = 0.5). Among cases under 60-days adjusted-age, urinalysis was not reliable to exclude UTI (50% negative). Conclusions: Well-appearing ex-preterm infants have a significant risk for IBI until the adjusted age of 28-days and for UTI until the adjusted age of 60-days. Further studies are needed to evaluate the approach to fever in this unique population.
