AbstractObjective:To explore the association of putative disease markers and potential risk factors with the nosocomial sepsis syndrome.Design:Prospective case-control study matched for gender, age, and length of preinfection hospital stay.Setting:1,200-bed tertiary-care center in Spain.Patients:Cases were selected using the sepsis syndrome criteria of the American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference and were divided into three groups: sepsis with bacteremia (109 cases), sepsis with positive culture other than blood (122 cases), and sepsis with negative culture (115 cases without documented infection but with sepsis syndrome, clinically suspected infection, and empirical antibiotic treatment). Controls were randomly selected from the daily list of inpatients. Data were collected prospectively. Crude and multiple-risk-factor-adjusted odds ratios and their 95% confidence intervals were computed using conditional logistic regression analysis.Results:Presence of coma in the 48 hours before sepsis, intensive care unit (ICU) stay, and decreased serum albumin levels at admission were common epidemiological markers identified for the three groups of cases. Having a central venous catheter was the main healthcare-related risk factor for bacteremia. ICU stay and nasogastric tube were the main risk factors for sepsis with positive culture other than blood. Coma within 48 hours before sepsis and the need of intensive care were the only two markers identified for culture-negative sepsis.Conclusion:Culture-negative sepsis does not behave like culture-positive sepsis, and this may imply that implementation of preventive measures to decrease the risk of bacteremia may not decrease the risk of sepsis syndrome.

Abstract OBJECTIVES The goal of this study was to identify the risk factors for prolonged length of stay (LOS) in the intensive care unit (ICU) after a bidirectional cavopulmonary shunt (BCPS) procedure and its impact on the number of deaths. METHODS In total, 556 patients who underwent BCPS between January 1998 and December 2019 were included in the study. RESULTS Eighteen patients died while in the ICU, and 35 died after discharge from the ICU. Reduced ventricular function was significantly associated with death during the ICU stay (P = 0.002). In patients who were discharged alive from the ICU, LOS in the ICU [hazard ratio (HR) 1.04, 95% confidence interval (CI) 1.02–1.06; P < 0.001] and a dominant right ventricle (HR 2.41, 95% CI 1.03–6.63; P = 0.04) were independent risk factors for death. Receiver operating characteristic analysis identified a cut-off value for length of ICU stay of 19 days. Mean pulmonary artery pressure (HR 1.03, 95% CI 1.01–1.05; P = 0.04) was a significant risk factor for a prolonged ICU stay. CONCLUSIONS Prolonged LOS in the ICU with a cut-off value of 19 days after BCPS was a significant risk factor for mortality. High pulmonary artery pressure at BCPS was a significant risk factor for a prolonged ICU stay.

World Health Organization’s Vision 2020 program has recognized Retinopathy of Prematurity(ROP) as an important cause of childhood blindness in industrialized and developing countries. Inthe last few years, it has been identifi ed in many under developed countries as well, as a result ofimproved neonatal intensive care. In Nepal, ROP screening is carried out in a few tertiary hospitalsbut there is no published data on this disease. The purpose of this study was to fi nd out the incidence,severity and risk factors of ROP among infants screened in a tertiary care hospital in the EasternRegion of Nepal.A prospective cohort study was carried out in neonates with gestational age of 34 weeks or less and,or birth weight of 1700 gm or less born over the period of one year. Dilated fundus examination ofall babies was done by indirect ophthalmoscopy between 2-4 weeks after birth and followed up tillthe retinal vascularization was complete. Classifi cation of ROP was done according to internationalclassifi cation (ICROP). Maternal and neonatal risk factors were also noted.A total of 55 babies fulfi lled the screening criteria. ROP was present in 25.45% (n=14) of the babies.Threshold disease was noted in 5.45% (n=3) of the babies screened. Low birth weight (p<0.01)and low gestational age (p<0.01) was signifi cantly associated with the incidence of ROP. Oxygensupplementation (p=<0.01) was an independent risk factor.ROP screening should be performed in all preterm low birth weight infants where there is availabilityof good neonatal intensive care units. The examination should be intensifi ed in those having riskfactors like oxygen. Further studies in the other tertiary care hospitals in Nepal would help toestablish the screening criteria for Nepalese infants.Key words: Retinopathy of prematurity, Eastern Nepal, screening

Objective. The aim of this study was to estimate the incidence of delirium and its risk factors among critically ill cancer patients in an intensive care unit (ICU). Materials and Methods. This is a prospective cohort study. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) was measured daily at morning to diagnose delirium by a physician. Delirium was diagnosed when the daily was positive during a patient’s ICU stay. All patients were followed until they were discharged from the ICU. Using logistic regression, we estimated potential risk factors for developing delirium. The primary outcome was the development of ICU delirium. Results. There were 109 patients included in the study. Patients had a mean age of 48.6 ± 18.07 years, and the main reason for admission to the ICU was septic shock (40.4%). The incidence of delirium was 22.9%. The mortality among all subjects was 15.6%; the mortality rate in patients who developed delirium was 12%. The only variable that had an association with the development of delirium in the ICU was the days of use of mechanical ventilation (OR: 1.06; CI 95%: 0.99–1.13;p=0.07). Conclusion. Delirium is a frequent condition in critically ill cancer patients admitted to the ICU. The duration in days of mechanical ventilation is potential risk factors for developing delirium during an ICU stay. Delirium was not associated with a higher rate of mortality in this group of patients.

ObjectiveTo assess the three key issues for congenital anomalies (CAs) prevention and care, namely, CA prevalence, risk factor prevalence and survival, in a longitudinal cohort in Riyadh, Saudi Arabia.SettingTertiary care centre, Riyadh, Saudi Arabia.ParticipantsSaudi women enrolled during pregnancy over 3 years and their 28 646 eligible pregnancy outcomes (births, stillbirths and elective terminations of pregnancy for foetal anomalies). The nested case-control study evaluated the CA risk factor profile of the underlying cohort. All CA cases (1179) and unaffected controls (1262) were followed through age 2 years. Referred mothers because of foetal anomaly and mothers who delivered outside the study centre and their pregnancy outcome were excluded.Primary outcome measuresPrevalence and pattern of major CAs, frequency of CA-related risk factors and survival through age 2 years.ResultsThe birth prevalence of CAs was 412/10 000 births (95% CI 388.6 to 434.9), driven mainly by congenital heart disease (148 per 10 000) (95% CI 134 to 162), renal malformations (113, 95% CI 110 to 125), neural tube defects (19, 95% CI 25.3 to 38.3) and chromosomal anomalies (27, 95% CI 21 to 33). In this study, the burden of potentially modifiable risk factors included high rates of diabetes (7.3%, OR 1.98, 95% CI 1.04 to 2.12), maternal age >40 years (7.0%, OR 2.1, 95% CI 1.35 to 3.3), consanguinity (54.5%, OR 1.5, 95% CI 1.28 to 1.81). The mortality for live births with CAs at 2 years of age was 15.8%.ConclusionsThis study documented specific opportunities to improve primary prevention and care. Specifically, folic acid fortification (the neural tube defect prevalence was >3 times that theoretically achievable by optimal fortification), preconception diabetes screening and consanguinity-related counselling could have significant and broad health benefits in this cohort and arguably in the larger Saudi population.

Objective.To examine the duration of methicillin-resistant Staphylococcus aureus (MRSA) carriage and its determinants and the influence of eradication regimens.Design.Retrospective cohort study.Setting.A 1,033-bed tertiary care university hospital in Bern, Switzerland, in which the prevalence of methicillin resistance amongS. aureusisolates is less than 5%.Patients.A total of 116 patients with first-time MRSA detection identified at University Hospital Bern between January 1, 2000, and December 31, 2003, were followed up for a mean duration of 16.2 months.Results.Sixty-eight patients (58.6%) cleared colonization, with a median time to clearance of 7.4 months. Independent determinants for shorter carriage duration were the absence of any modifiable risk factor (receipt of antibiotics, use of an indwelling device, or presence of a skin lesion) (hazard ratio [HR], 0.20 [95% confidence interval {CI}, 0.09-0.42]), absence of immunosuppressive therapy (HR, 0.49 [95% CI, 0.23-1.02]), and hemodialysis (HR, 0.08 [95% CI, 0.01-0.66]) at the time MRSA was first MRSA detected and the administration of decolonization regimen in the absence of a modifiable risk factor (HR, 2.22 [95% CI, 1.36-3.64]). Failure of decolonization treatment was associated with the presence of risk factors at the time of treatment (P= .01). Intermittent screenings that were negative for MRSA were frequent (26% of patients), occurred early after first detection of MRSA (median, 31.5 days), and were associated with a lower probability of clearing colonization (HR, 0.34 [95% CI, 0.17-0.67]) and an increased risk of MRSA infection during follow-up.Conclusions.Risk factors for MRSA acquisition should be carefully assessed in all MRSA carriers and should be included in infection control policies, such as the timing of decolonization treatment, the definition of MRSA clearance, and the decision of when to suspend isolation measures.

Abstract PURPOSE: Vancomycin-resistant enterococci (VRE) emerged as one of the major nosocomial pathogens across the globe. Gut colonization rate with VRE is higher in patients admitted to intensive care units (ICUs) due to the higher antibiotic pressure. VRE colonization increases the risk of developing infection up to 5–10 folds. The aim of this study was to determine the rates of VRE colonization among the patients admitted to pediatric ICU (PICU) and risk factors associated with it. MATERIALS AND METHODS: Rectal swabs were collected after 48 h of admission to PICU from 198 patients. The samples were inoculated onto bile esculin sodium azide agar with 6 mg/ml of vancomycin. Growth on this medium was identified by the standard biochemical test, and minimum inhibitory concentration of vancomycin and teicoplanin was detected by agar dilution method. Resistance genes for vancomycin were detected by polymerase chain reaction. Risk factors were assessed by logistic regression analysis. RESULTS: The rates of VRE colonization in patients admitted to PICU was 18.6%. The majority of the isolates were Enterococcus faecium (75.6%) followed by Enterococcus faecalis (24.4%). One patient acquired a VRE bloodstream infection (2.6%) among colonized patients, and none of the noncolonized patients acquired the infection. Consumption of vancomycin was found to be the only risk factor significantly associated with VRE colonization. CONCLUSION: Routine surveillance and isolation of patients found to be VRE colonized may not be possible in tertiary care hospitals; however, educating health-care workers, promoting handwashing with antiseptic soaps or solutions, and antibiotic Stewardship policy may help in the reduction of vancomycin resistance and VRE colonization.

Nosocomial Sepsis

Introduction: Nosocomial sepsis is a common and serious infection of neonates who are admitted in intensive care unit. They lead to significant morbidity and mortality in both developed and resource limited countries. The neonatal intensive care unit (NICU) is a suitable environment for disseminating the infections and, hence, needs preventive intervention. The study was carried out to determine the risk factors for nosocomial sepsis in neonatal intensive care unit. Material and Methods: This was a cross-sectional study conducted in a seven bedded teaching and referral hospital NICU. All neonates in NICU who did not have any sign of infection at admission and remained hospitalized for at least 48 hours were observed. Nosocomial sepsis was diagnosed according to the CDC criteria. Risk factors for nosocomial sepsis were analyzed with Chi-square test and Logistic regression model. P-value of <0.05 was considered significant. Results: Low birth weight (both preterm and IUGR) and mechanical ventilation were found to be related with nosocomial sepsis. Conclusions: Low birth weight and mechanical ventilation were the most important risk factors fornosocomial sepsis.

Background: Plantar plate pathology is common, yet it is unclear whether, and to what extent, the length of the second metatarsal contributes to this problem. Methods: We conducted a retrospective case-control (1:2) study to examine radiographic risk factors for plantar plate tears. One hundred patients (age 55.7 ± 12.3 years) with plantar plate injuries and 200 healthy controls (age 56.3 ± 11.3 years) were included. Cases were defined as patients with nonacute, isolated, plantar plate pathology of the second metatarsophalangeal joint confirmed by intraoperative inspection at a single foot and ankle specialty practice from June 1, 2007, to January 31, 2014. Patients presenting for pain outside of the forefoot served as the control group. Controls were matched on age (±2 years), gender, and year of presentation. Weight-bearing foot x-rays were assessed for several predetermined angular relationships by a single rater. Conditional logistic regression was used to identify risk factors for plantar plate injury. Results: A long second metatarsal, defined as a metatarsal protrusion index less than −4 mm, was the only significant risk factor for plantar plate pathology in both the univariate and multivariable analyses (multivariate odds ratio 2.5 [95% confidence interval 1.8 to 3.3], P = .002). Conclusion: We found that a long second metatarsal was a risk factor for developing second metatarsophalangeal joint plantar plate tears. This knowledge may aid foot and ankle surgeons when contemplating the need for second metatarsal shortening osteotomies (eg, Weil osteotomy) during plantar plate surgery and when deciding on the amount of shortening for second metatarsal osteotomies. Level of Evidence: Level III, retrospective comparative study.

Purpose: Acute kidney injury (AKI) is a severe complication in medical and surgical intensive care units accounting for a high morbidity and mortality. Incidence, risk factors, and prognostic impact of this deleterious condition are well established in this setting. Data concerning the neurocritically ill patients is scarce. Therefore, aim of this study was to determine the incidence of AKI and elucidate risk factors in this special population. Methods: Patients admitted to a specialized neurocritical care unit between 2005 and 2011 with a length of stay above 48 hours were analyzed retrospectively for incidence, cause, and outcome of AKI (AKI Network-stage ≥2). Results: The study population comprised 681 neurocritically ill patients from a mixed neurosurgical and neurological intensive care unit. The prevalence of chronic kidney disease (CKD) was 8.4% (57/681). Overall incidence of AKI was 11.6% with 36 (45.6%) patients developing dialysis-requiring AKI. Sepsis was the main cause of AKI in nearly 50% of patients. Acute kidney injury and renal replacement therapy are independent predictors of worse outcome (hazard ratio [HR]: 3.704; 95% confidence interval [CI]: 1.867-7.350; P < .001; and HR: 2.848; CI: 1.301-6.325; P = .009). Chronic kidney disease was the strongest independent risk factor (odds ratio: 12.473; CI: 5.944-26.172; P < .001), whereas surgical intervention or contrast agents were not associated with AKI. Conclusions: Acute kidney injury in neurocritical care has a high incidence and is a crucial risk factor for mortality independently of the underlying neurocritical condition. Sepsis is the main cause of AKI in this setting. Therefore, careful prevention of infectious complications and considering CKD in treatment decisions may lower the incidence of AKI and hereby improve outcome in neurocritical care.
