ABSTRACT

BACKGROUND: Clinical practice guidelines (CPGs) have been associated with improved patient outcomes. We aimed to evaluate institutional CPG adherence and hypothesized that adherence would be associated with fewer complications in pediatric appendicitis. METHODS: A retrospective review was conducted of pediatric (<18 y) appendicitis patients who underwent appendectomy (6/1/2017-5/30/2018). Patients were managed using an institutional pediatric appendicitis CPG. The primary outcome was CPG adherence, defined as receipt of preoperative antibiotics at diagnosis, surgical prophylaxis before incision, and, in perforated/gangrenous appendicitis, continued postoperative antibiotics, and prescription for discharge antibiotics. Univariate and multivariate analyzes were performed. RESULTS: Among 399 patients, the baseline characteristics were similar between CPG-adherent and nonadherent patients. Overall CPG adherence was low at 55% (n = 221). Only 58% of patients received preoperative antibiotics per protocol (n = 233). Patients with simple appendicitis were more likely to proceed to surgery without receiving any preoperative antibiotics (35% vs. 21%, P = 0.004). Surgical prophylaxis compliance was high at 97% (n = 389). CPG violation was associated with reoperation (n = 5 versus 0, P = 0.02). After adjusting for age and admission white blood cell count, the association between CPG adherence and postoperative surgical site infection or intra-abdominal abscess remained nonsignificant (OR: 1.2, 95% CI: 0.5-2.5). CONCLUSIONS: Despite a long-standing pediatric appendicitis CPG, adherence with antibiotic components of the CPG was poor. CPG violation was significantly associated with reoperation, but was not associated with other postoperative complications. Regular audits of CPG adherence are necessary to ascertain reasons for noncompliance and identify ways to improve adherence.

ABSTRACT

The pathogenesis and etiology of schizophrenia (SCZ) remains unclear. Accumulating studies showed that complex interrelationships between brain-derived neurotrophic factor (BDNF) and an imbalanced redox system has a crucial role in the psychopathology of SCZ. However, the influence of the interrelationships of BDNF and superoxide dismutase (SOD) on cognitive impairment and clinical symptomatology in drug-naive first-episode (DNFE) SCZ patients has not been studied thoroughly. Serum BDNF levels, plasma total SOD, manganese-SOD (Mn-SOD), copper/zinc-containing SOD (CuZn-SOD) activities, and malondialdehyde (MDA) levels were measured in 327 DNFE patients with SCZ and 391 healthy controls. Cognitive functions were measured using the Repeatable Battery for the Assessment of Neuropsychological status (RBANS) and clinical symptoms were evaluated by the Positive and Negative Syndrome Scale (PANSS). Compared with the controls, the DNFE patients had increased activities of total SOD and CuZn-SOD, and reduced levels of BDNF and MDA. BDNF levels were positively correlated with CuZn-SOD activity in patients. In addition, we found that elevated Mn-SOD and CuZn-SOD activities were related to PANSS depression factor. Moreover, an interactive effect of BDNF levels and Mn-SOD activity was associated with attentional index score in the patients. Therefore, our findings suggested that interrelationships between BDNF and antioxidant mechanisms might underlie the pathological mechanisms of cognitive impairments and symptomatology in the DNFE patients with SCZ.

ABSTRACT

Nail-patella syndrome (NPS) or hereditary onycho-osteodyaplasia is a rare genetic condition involving a mutation in the LMX1B gene affecting nails, elbows, knees, and pelvis. Due to the regulatory functions of the gene in many developmental processes through the body, patients with NPS experience wide-ranging musculoskeletal problems including patellar instability, fingernail anomalies, iliac exostoses/horns, and elbow abnormalities. The patellar changes often involve aplasia, hypoplasia, and chronic dislocation. Due to these musculoskeletal involvement, arthritis of joints can occur in patients with NPS causing severe pain and disability. This is a case report of a patient with NPS who underwent a total knee arthroplasty for symptomatic knee arthritis.
