Modified Early Warning Score (MEWS) as a predictor of intensive care unit admission in cancer patient on chemotherapy with positive blood culture: A retrospective cohort study.

BACKGROUND: Although the usefulness of the Modified Early Warning Score (MEWS) in predicting clinical deterioration or the need for intensive care unit (ICU) admission has been evaluated in several studies, only few reports have considered the immune status of the patient. Patients receiving chemotherapy for cancer are at risk of sepsis. This study aimed to assess the validity of MEWS in predicting clinical deterioration, ICU admission, and mortality among immunocompromised cancer patients on chemotherapy (CPOC). METHODS: This retrospective cohort study was conducted at a tertiary care center in Jeddah, Saudi Arabia. Subjects aged>14 years with positive blood cultures, who were hospitalized between June 2016 and June 2017, were included. MEWS was calculated at different time intervals: before, after, and at the time (0-time) of positive blood culture. RESULTS: Overall, 192 patients were enrolled, including 89 CPOC and 103 immunocompetent individuals (controls). ICU admission rate was significantly lower in the CPOC group than in the control group (21 % vs. 50 %, P < .001). Positive MEWS rate (score ≥4) at 0-time was lower in the CPOC group, but the difference was not significant (39.7 % vs. 60.3 %, P = .129). In the CPOC group, positive MEWS rate (score ≥4) had a sensitivity, specificity, positive predictive value, and negative predictive value of 52.6 %, 70 %, 32.3 %, and 84 %, respectively, which was comparable to that observed in the control group. Furthermore, the receiver operating characteristic curve in the CPOC group showed that MEWS calculated 12-36 h before positive blood culture was a significant predictor of ICU admission. The optimal threshold of MEWS with the best sensitivity and specificity was ≥ 3 for the CPOC group and ≥ 4 for the control group to predict ICU admission. MEWS was a generally poor predictor of mortality. CONCLUSION: MEWS ≥ 3 calculated 12-36 h before positive blood culture is the best predictor of ICU admission for CPOC.

Epidemiology of pediatric sepsis in the pediatric intensive care unit of king Abdulaziz Medical City, Jeddah, Saudi Arabia.

BACKGROUND: Pediatric sepsis remains a significant cause of morbidity and mortality worldwide. This study aimed to identify the incidence of sepsis and septic shock among patients admitted to the pediatric intensive care unit (PICU) of a tertiary center in Saudi Arabia.  Patients' demographics and risk factors associated with sepsis-related mortality were also investigated. METHODS: A retrospective cohort study was conducted in the PICU of King Abdulaziz Medical City, Jeddah (KAMC-J). KAMC-J is a tertiary care hospital in the western region of Saudi Arabia. A total of 2389 patients admitted to the PICU of KAMC-J between January 1, 2013 and December 31, 2017 were screened and evaluated for sepsis using The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). RESULTS: Of the 2389 total admissions to the PICU, 113 patients (4.9%) met the definition of Sepsis-3; 50.4% of the 113 patients met the definition of septic shock. Most patients (66.3%) were less than 6 years old, and 52.2% were male. Eight-five patients (75.2%) had underlying comorbidities. The respiratory system was the most common primary site of infection (57.5%). Bacterial and viral infections were the most common infectious etiology with reported rates of 29.2 and 21.2%, respectively. The median duration of PICU stay was 8 days and the 28-day PICU mortality rate was 23.9%. A Pediatric Sequential Organ Failure Assessment (pSOFA) Score greater than four and a pre-existing percutaneous central venous catheter were associated with a significant increase in mortality, with adjusted odds ratios of 3.6 (95% confidence interval: 1.30-9.93) and 9.27 (95% confidence interval: 1.28-67.29), respectively. CONCLUSIONS: The incidence of sepsis in our institution is comparable to that reported internationally; however, the mortality rate is higher than that of developed countries. Nationwide studies identifying sepsis epidemiology are needed to improve the outcome of pediatric sepsis. Following international guidelines for central-line insertion and maintenance is of paramount importance.

Isolated hypoplasia of the abdominal wall associated with fetal parvovirus B19 infection.

We report a rare case of a preterm infant with a diagnosis of hydrops fetalis, associated with parvovirus B19 infection. At birth, the infant had severe ascites. She recovered and was discharged in later good condition. In follow-up at 10 years of age, she still had severe isolated hypoplasia of the abdominal muscles. Isolated hypoplasia of the abdominal muscles after parvovirus B19 infection appears to be a separate entity, which should be differentiated from other abdominal wall anomalies.

Cytomegalovirus viremia among pediatric oncology non-stem cell transplant patients with prolonged fever neutropenia.

BACKGROUND: Cytomegalovirus (CMV) is a rare cause of prolonged febrile neutropenia (PFN) among pediatric oncology patients, especially in non-stem cell transplant setting (Non-SCTS). Infectious Diseases Society of America (IDSA) guidelines stated briefly that neutropenia is not considered as an indication of CMV re-activation, and thus preventive strategies are not needed; however, multiple studies pressed on the need to treat CMV viremia among patients with PFN even when there is no evidence of end-organ involvement. Therefore, this study aimed to prospectively investigate the significance of CMV as a cause of PFN among pediatric oncology patients in a Non-SCTS. PATIENTS AND METHODS: This was a prospective cohort study that was done at Princess Norah Oncology Center, King Abdulaziz Medical City in Jeddah, Saudi Arabia. CMV viral load was monitored weekly once the subject was identified as a case of PFN until resolution. Subjects and treating physicians were blinded to CMV viral load results. RESULTS: The data of 27 PFN episodes (48% males) were analyzed. The incidence of CMV viremia was reported as 29.6%. Both CMV positive and negative episodes of PFN had similar rate of spontaneous resolution (p=0.669), with overall mortality as 105 and 125 per 1000 PFN episodes, respectively. No subject received anti-CMV in the positive CMV group; however, one subject did in the negative group for reasons other than CMV infection. CONCLUSION: This study demonstrated that CMV was not a significant cause of PFN in Non-SCTS. CMV also had no significant role in terms of survival and severity of the PFN episode.

The incidence of ventilator-associated pneumonia (VAP) in a tertiary-care center: Comparison between pre- and post-VAP prevention bundle.

INTRODUCTION: Ventilator-associated pneumonia (VAP) is a nosocomial infection that develops 48h after the initiation of mechanical ventilatory support. Current evidence-based guidelines demonstrate that VAP prevention is feasible through the implementation of certain VAP prevention bundle of interventions simultaneously. We aimed in this study to investigate the effect of VAP prevention pre- and post- implementation. METHODS: This is a single-center, cohort study that took place at the Pediatric Intensive Care Unit (PICU) of King Abdulaziz Medical City (KAMC), Jeddah, Saudi Arabia from January 2015 to March 2018 and assessed the rate of VAP before and after implementation of the bundle. RESULTS: The study included 141 children, 95 were included from the pre-bundle group and 36 from the bundle group. VAP developed in 35% of the pre-bundle group compared to 31% of the bundle group (p=0.651) with incidence rates equaled to 18 and 12 per 1000 ventilator days, respectively. CONCLUSION: This study found that VAP bundle did not significantly reduce VAP rate in the PICU. Further large prospective multi-center studies with longer intervention duration are indicated to investigate the benefits of using VAP prevention bundle.
