A role for counselling psychologists within the Neonatal Intensive Care Unit

Counselling psychology appears to be neglecting the importance and merits of working with the client population associated with the preterm neonate within the Neonatal Intensive Care Unit (NICU). Throughout, the benefits of such a move are highlighted with particular emphasis on how counselling psychologists are uniquely qualified for this role. Specialist knowledge required to provide clients with the greatest therapeutic gains illustrates the pertinent issues, with proposals for clinical practice put forward. NHS Trusts nationwide are encouraged to recruit this ready-made professional into the Department for the psychological health of parents and caregivers engaged in caring for the preterm neonate.     

神经外科重症监护室发热及其治疗

发热是神经外科重症监护室(Neurosurgical intensive care unit,NICU)最常见的症状之一,它是人体对损伤的保护性反应,但同时又加重了机体的负担,从而恶化临床结局。NICU发热起因复杂并相互交错,仅少部分有特异性表现,并且总上而言处理困难。因此系统地了解发热的起因、处理以及预后是非常重要的。尽管过去的文献对于发热已有很好的研究,然而缺乏对NICU发热的系统性描述。我们通过回顾文献系统性地总结了NICU发热,旨在进一步增进对NICU发热的认识从而有利于临床诊治。     

Fungemia by Candida pelliculosa (Pichia anomala) in a Neonatal Intensive Care Unit: A Possible Clonal Origin

Neonatal candidemia can occur, however, infections caused by Candida pelliculosa are rare. Here, we describe an outbreak of candidemia caused by C. pelliculosa among babies hospitalized in a neonatal intensive care unit.     

Invasive Mycosis in Medical Intensive Care Unit Patients with Severe Alcoholic Hepatitis

Background

Severe alcoholic hepatitis (AH) has a poor short-term prognosis often caused by infections. However, the incidence of invasive mycosis in patients with AH treated with corticosteroids and its impact still remains unknown.

Methods

Retrospective analyses of twelve medical ICU patients (out of 120 patients with liver cirrhosis) with histological proven AH.

Results

Twelve patients were diagnosed with histological proven AH during there stay at the ICU. All patients were treated with corticosteroids; three patients were treated with corticosteroids and pentoxifylline. Five patients had invasive aspergillosis (IA); three patients had candidemia; and two had fungal colonization with candida species. Only two patients had no evidence for fungals. IA was associated with death in all cases. Death occured in most cases shortly after diagnosis despite antifungal medication. Two patients with candidemia died; one patient died in the group with fungal colonization. Overall, the mortality rate was 100 % in patients with IA and 70 % in the group with candidemia.

Conclusions

Patients with severe AH have an increased susceptibility to invasive mycosis associated with high mortality. A high level of suspicion of invasive mycosis in AH patients and prophylactic strategies are needed in those patients.     

Aspergillus in the Intensive Care Unit

Invasive aspergillosis (IA), the most life-threatening form of aspergillosis, has become a major opportunistic fungal disease in immunocompromised patients. In high-risk patients with hematologic malignancies, IA appears to decline with the use of mold-active antifungal prophylaxis, but the situation is less clear in other patient groups at risk for IA, and precise epidemiologic data from patients treated in intensive care units (ICUs) are lacking. Most Aspergillus culture isolates from nonsterile body sites do not represent disease, but isolation of Aspergillus in critically ill patients is a marker of poor prognosis and is associated with high mortality regardless of invasion or colonization. This review presents current information on epidemiology, risk factors, and diagnosis, and discusses treatment options for patients with IA in the ICU.     

Incidence,Clinical Characteristics and Attributable Mortality of Persistent Bloodstream Infection in the Neonatal Intensive Care Unit

Background

An atypical pattern of neonatal sepsis, characterized by persistent positive blood culture despite effective antimicrobial therapy, has been correlated with adverse outcomes. However, previous studies focused only on coagulate-negative staphylococcus infection.

Methods

All episodes of persistent bloodstream infection (BSI), defined as 3 or more consecutive positive blood cultures with the same bacterial species, at least two of them 48 hours apart, during a single sepsis episode, were enrolled over an 8-year period in a tertiary level neonatal intensive care unit. These cases were compared with all non-persistent BSI during the same period.

Results

We identified 81 episodes of persistent BSI (8.5% of all neonatal late-onset sepsis) in 74 infants, caused by gram-positive pathogens (n=38, 46.9%), gram-negative pathogens (n=21, 25.9%), fungus (n=20, 24.7%) and polymicrobial bacteremia (n=2, 2.5%). Persistent BSI does not differ from non-persistent BSI in most clinical characteristics and patient demographics, but tends to have a prolonged septic course, longer duration of feeding intolerance and more frequent requirement of blood transfusions. No difference was observed for death attributable to infection (9.8% vs. 6.5%), but neonates with persistent BSI had significantly higher rates of infectious complications (29.6% vs. 9.2%, P < 0.001), death from all causes (21.6% vs. 11.7%, P = 0.025), and duration of hospitalization among survivors [median (interquartile range): 80.0 (52.5-117.5) vs. 64.0 (40.0-96.0) days, P = 0.005] than those without persistent BSI.

Conclusions

Although persistent BSI does not contribute directly to increased mortality, the associated morbidities, infectious complications and prolonged septic courses highlight the importance of aggressive treatment to optimize outcomes.     

Antifungal Prophylaxis in the Pediatric Intensive Care Unit

Invasive fungal infections in children have shown a dramatic increase over the last two decades. Their importance and clinical implications are more prominent in selected groups of patients such as critically ill children in the pediatric intensive care unit (PICU). This population constitutes an important target for prophylactic antifungal interventions. While antifungal agents have been studied in various clinical settings, knowledge in this particular setting is rather scant. The current data suggest that antifungal prophylaxis in the PICU setting should be tailored to the needs of each patient guided by the individual’s risk factors and local epidemiology.

     

Bloodstream Infections in the Intensive Care Unit: A Single-Center Retrospective Bacteriological Analysis Between 2007 and 2019

Hospital-acquired bloodstream infections are a severe worldwide problem associated with significant morbidity and mortality. This retrospective, single-center study aimed to analyze bloodstream infections in patients hospitalized in the intensive care unit of the Military Institute of Medicine, Poland. Data from the years 2007–2019 were analyzed. When the infection was suspected, blood samples were drawn and analyzed microbiologically. When bacterial growth was observed, an antimicrobial susceptibility/resistance analysis was performed. Among 12,619 analyzed samples, 1,509 were positive, and 1,557 pathogens were isolated. In 278/1,509 of the positive cases, a central line catheter infection was confirmed. Gram-negative bacteria were the most frequently (770/1,557) isolated, including Acinetobacter baumannii (312/770), Klebsiella pneumoniae (165/770; 67/165 were the isolates that expressed extended spectrum beta-lactamases (ESBL), 5/165 isolates produced the New Delhi metallo-β-lactamases (NDM), 4/165 isolates expressed Klebsiella pneumoniae carbapenemase (KPC), and 1/165 isolate produced OXA48 carbapenemase), Pseudomonas aeruginosa (111/770; 2/111 isolates produced metallo-β-lactamase (MBL), and Escherichia coli (69/770; 11/69 – ESBL). Most Gram-positive pathogens were staphylococci (545/733), mainly coagulase-negative (368/545). Among 545 isolates of the staphylococci, 58 represented methicillin-resistant Staphylococcus aureus (MRSA). Fungi were isolated from 3.5% of samples. All isolated MRSA and methicillin-resistant coagulase-negative Staphylococcus (MRCNS) strains were susceptible to vancomycin, methicillin-sensitive Staphylococcus aureus (MSSA) isolates – to isoxazolyl penicillins, and vancomycin-resistant Enterococcus (VRE) – to linezolid and tigecycline. However, colistin was the only therapeutic option in some infections caused by A. baumannii and KPC-producing K. pneumoniae. P. aeruginosa was still susceptible to cefepime and ceftazidime. Echinocandins were effective therapeutics in the treatment of fungal infections.     

Fungal Infections in COVID-19 Intensive Care Patients

Opportunistic fungal infections increase morbidity and mortality in COVID-19 patients monitored in intensive care units (ICU). As patients’ hospitalization days in the ICU and intubation period increase, opportunistic infections also increase, which prolongs hospital stay days and elevates costs. The study aimed to describe the profile of fungal infections and identify the risk factors associated with mortality in COVID-19 intensive care patients. The records of 627 patients hospitalized in ICU with the diagnosis of COVID-19 were investigated from electronic health records and hospitalization files. The demographic characteristics (age, gender), the number of ICU hospitalization days and mortality rates, APACHE II scores, accompanying diseases, antibiotic-steroid treatments taken during hospitalization, and microbiological results (blood, urine, tracheal aspirate samples) of the patients were recorded. Opportunistic fungal infection was detected in 32 patients (5.10%) of 627 patients monitored in ICU with a COVID-19 diagnosis. The average APACHE II score of the patients was 28 ± 6. While 25 of the patients (78.12%) died, seven (21.87%) were discharged from the ICU. Candida parapsilosis (43.7%) was the opportunistic fungal agent isolated from most blood samples taken from COVID-19 positive patients. The mortality rate of COVID-19 positive patients with candidemia was 80%. While two out of the three patients (66.6%) for whom fungi were grown from their tracheal aspirate died, one patient (33.3%) was transferred to the ward. Opportunistic fungal infections increase the mortality rate of COVID-19-positive patients. In addition to the risk factors that we cannot change, invasive procedures should be avoided, constant blood sugar regulation should be applied, and unnecessary antibiotics use should be avoided.     

Management of High-Risk Pregnancy: Report of a Combined Obstetrical and Neonatal Intensive Care Unit

The methodology, equipment and personnel required to carry out an intensive-care program in the management of high-risk pregnancies have been outlined. The perinatal mortality rate has been determined and its etiology has been analyzed.There appear to be three conditions in which the degree of high risk is such as to warrant provision of the complete facilities of the service we described, viz., (a) severe pre-eclampsia; (b) marked intrauterine growth retardation with placental insufficiency as determined from serial measurements of uterine growth and estriol determinations; and (c) irreversible labour in premature pregnancies where a birth weight of 2200 g. or less is anticipated. Numerous other conditions that we have monitored have perhaps had their good outcome because of monitoring facilities. A less sophisticated and more easily applied method of monitoring should be available within the context of routine labour and delivery rooms.There is a pressing need to re-evaluate and change some of our methods of educating our undergraduate, postgraduate and practising physicians and to provide continuing education in the realm of prenatal care and recognition of high-risk pregnancy. Regionalization and centralization of this type of intensive care for high-risk pregnancies are required.Indispensable to the success of this type of project is the incorporation, without physical, emotional or intellectual barriers, of both a pediatric and an obstetrical component within the intensive-care unit.     

Life-and-Death Decisions in a Neonatal Intensive Care Unit in Denmark: The Discrete Authority of Origin Stories

In what ways are care and compassion implicated in efforts to establish lives worth living? Drawing on fieldwork in a Danish Neonatal Intensive Care Unit (NICU), in this article we investigate the role of family biographies in conducting life-and-death decisions around premature infants. Guided by a larger literature on citizenship, we view decisions in the NICU as political acts of assigning citizenship. We ask what bodies and biographies can generate and evoke care and compassion among NICU staff and forge entries or exits from the Danish Welfare State. We demonstrate that infants’ origin stories are appointed legitimate forms of suffering in contemporary Danish society and are thus granted an unnoticed form of authority in life-and-death decisions. In this way, we conclude that what comes to constitute a life worth living in the twenty-first-century Danish Welfare State is in fact the worth of the family.     

First Outbreak with MRSA in a Danish Neonatal Intensive Care Unit: Risk Factors and Control Procedures

Introduction

The purpose of the study was to describe demographic and clinical characteristics and outbreak handling of a large methicillin-resistant Staphylococcus aureus (MRSA) outbreak in a neonatal intensive care unit (NICU) in Denmark June 25^th–August 8^th 2008, and to identify risk factors for MRSA transmission.

Methods

Data were collected retrospectively from medical records and the Danish Neobase database. All MRSA isolates obtained from neonates, relatives and NICU health care workers (HCW) as well as environmental cultures were typed.

Results

During the 46 day outbreak period, 102 neonates were admitted to the two neonatal wards. Ninety-nine neonates were subsequently sampled, and 32 neonates (32%) from 25 families were colonized with MRSA (spa-type t127, SCCmec V, PVL negative). Thirteen family members from 11 of those families (44%) and two of 161 HCWs (1%) were colonized with the same MRSA. No one was infected. Five environmental cultures were MRSA positive. In a multiple logistic regression analysis, nasal Continuous Positive Airway Pressure (nCPAP) treatment (p = 0.006) and Caesarean section (p = 0.016) were independent risk factors for MRSA acquisition, whereas days of exposure to MRSA was a risk factors in the unadjusted analysis (p = 0.04).

Conclusions

MRSA transmission occurs with high frequency in the NICU during hospitalization with unidentified MRSA neonates. Caesarean section and nCPAP treatment were identified as risk factors for MRSA colonization. The MRSA outbreak was controlled through infection control procedures.     

Evaluation of mRNA Biomarkers to Identify Risk of Hospital Acquired Infections in Children Admitted to Paediatric Intensive Care Unit

Objectives

Hospital-acquired infections (HAI) are associated with significant mortality and morbidity and prolongation of hospital stay, adding strain on limited hospital resources. Despite stringent infection control practices some children remain at high risk of developing HAI. The development of biomarkers which could identify these patients would be useful. In this study our objective was to evaluate mRNA candidate biomarkers for HAI prediction in a pediatric intensive care unit.

Design

Serial blood samples were collected from patients admitted to pediatric intensive care unit between March and June 2012. Candidate gene expression (IL1B, TNF, IL10, CD3D, BCL2, BID) was quantified using RT-qPCR. Comparisons of relative gene expression between those that did not develop HAI versus those that did were performed using Mann Whitney U-test.

Patients

Exclusion criteria were: age <28 days or ≥16 years, expected length of stay < 24 hours, expected survival < 28 days, end-stage renal disease and end-stage liver disease. Finally, 45 children were included in this study.

Main Results

The overall HAI rate was 30% of which 62% were respiratory infections. Children who developed HAI had a three-fold increase in hospital stay compared to those who did not (27 days versus 9 days, p<0.001). An increased expression of cytokine genes (IL1B and IL10) was observed in patients who developed HAI, as well as a pro-apoptosis pattern (higher expression of BID and lower expression of BCL2). CD3D, a key TCR co-factor was also significantly down-modulated in patients who developed HAI.

Conclusions

To our knowledge, this is the first study of mRNA biomarkers of HAI in the paediatric population. Increased mRNA expressions of anti-inflammatory cytokine and modulation of apoptotic genes suggest the development of immunosuppression in critically ill children. Immune monitoring using a panel of genes may offer a novel stratification tool to identify HAI risk.     

Multipurpose Intensive Care Unit in a District General Hospital

The advantages of a four-bedded purpose-built general intensive care unit in a district general hospital are described. In addition to 1,447 inpatients treated between January 1968 and December 1971 the unit was used to conduct outpatient investigations. This has filled an important gap in conventional arrangements, and is practical and economical. The unit has proved to have advantages, not only for seriously ill patients but also has benefited the hospital in other ways. It has been of material assistance in recruiting and training nursing and medical staff and has been welcomed and supported by patients and their relatives. It has also attracted practical support from voluntary organizations whose generosity has enabled much additional equipment to be purchased.     

High Proportion of Intestinal Colonization with Successful Epidemic Clones of ESBL-Producing Enterobacteriaceae in a Neonatal Intensive Care Unit in Ecuador

Background and Aims

Neonatal infections caused by Extended-spectrum beta-lactamase (ESBL)-producing bacteria are associated with increased morbidity and mortality. No data are available on neonatal colonization with ESBL-producing bacteria in Ecuador. The aim of this study was to determine the proportion of intestinal colonization with ESBL-producing Enterobacteriaceae, their resistance pattern and risk factors of colonization in a neonatal intensive care unit in Ecuador.

Methods

During a three month period, stool specimens were collected every two weeks from hospitalized neonates. Species identification and susceptibility testing were performed with Vitek2, epidemiologic typing with automated repetitive PCR. Associations between groups were analyzed using the Pearson _X ² test and Fisher exact test. A forward step logistic regression model identified significant predictors for colonization.

Results

Fifty-six percent of the neonates were colonized with ESBL-producing Enterobacteriaceae. Length of stay longer than 20 days and enteral feeding with a combination of breastfeeding and formula feeding were significantly associated with ESBL-colonization. The strains found were E. coli (EC, 89%) and K. pneumoniae (KP, 11%) and epidemiological typing divided these isolates in two major clusters. All EC and KP had bla _CTX-M group 1 except for a unique EC isolate that had bla _CTX-M group 9. Multi-locus sequence typing performed on the K. pneumoniae strains showed that the strains belonged to ST855 and ST897. The two detected STs belong to two different epidemic clonal complexes (CC), CC11 and CC14, which previously have been associated with dissemination of carbapenemases. None of the E. coli strains belonged to the epidemic ST 131 clone.

Conclusions

More than half of the neonates were colonized with ESBL-producing Enterobacteriaceae where the main risk factor for colonization was length of hospital stay. Two of the isolated clones were epidemic and known to disseminate carbapenemases. The results underline the necessity for improved surveillance and infection control in this context.     

The Planning and Operation of an Intensive Care Unit

It is desirable that every hospital of 100 beds or more should have an intensive care unit. An attempt is made to outline the more important features to be considered, including the physical aspects, when planning and establishing such a unit. The unit should contain 2-4% of the total number of hospital beds. It should be separate, centrally located and self-contained. Direct observation of all patients must be possible at all times. Efficient and specially trained personnel using modern and special equipment are required. Orientation lectures and demonstrations must be carried out frequently and regularly. The types of patients to be admitted to the unit are discussed, as well as the governing rules and regulations. All doctors should have a right to admit and look after their own patients in the unit; an Intensive Care Unit Committee made up of representatives of the major services is suggested as a means of controlling admissions and discharges and for general administration.     

Continued Surveillance of Serratia marcescens Infections by Bacteriocin Typing: Investigation of Two Outbreaks of Cross-Infection in an Intensive Care Unit

During an 8.5-month period, 198 additional isolates of Serratia marcescens were typed by bacteriocin sensitivity; 154 isolates were typable and were categorized according to our current system of 54 provisional bacteriocin sensitivity patterns. Two outbreaks of nosocomial infection due to S. marcescens occurred in our intensive care unit, involving two and five patients, respectively. The latter outbreak was caused by a strain of S. marcescens which was not sensitive to any of the 10 bacteriocins normally used. Therefore we developed a supplementary procedure based on bacteriocin production rather than bacteriocin sensitivity. Bacteriocin production was induced with mitomycin C, and the crude lysates were applied to 15 provisional bacteriocin indicator strains. The reverse typing procedure was necessary to determine the spread and ultimate subsidence of this particular outbreak of cross-infection.     

Characterizing Glucose Changes Antecedent to Hypoglycemic Events in the Intensive Care Unit

ObjectiveTo determine whether patterns of glucose changes before hypoglycemia vary according to the severity of the event.MethodsIn this retrospective analysis, point-ofcare blood glucose (POC-BG) data were obtained from the intensive care units (ICUs) of a convenience sample of hospitals that responded to a survey on inpatient diabetes management quality improvement initiatives. To evaluate POC-BG levels before hypoglycemic events, data from patients who experienced hypoglycemia during their time in the ICU were examined, and their glucose changes were assessed against a comparison group of patients who achieved a glycemic range of 80 to 110 mg/dL without ever experiencing hypoglycemia. Absolute glucose decrease, glucose rate of change, and glucose variability before hypoglycemic events (< 40, 40-49, 50-59, and 60-69 mg/ dL) were calculated.ResultsA total of 128 419 POC-BG measurements from 2942 patients in 89 ICUs were analyzed. Patients who experienced the most severe hypoglycemic episodes had the largest absolute drop in their glucose levels before the event (P < .001). The glucose rate of change before a hypoglycemic event increased with worsening hypoglycemia: mean (± standard deviation) glucose rate of change was-1.69 (± 2.98) mg/dL per min before an episode with glucose values less than 40 mg/dL, -0.56 (± 2.65) mg/dL per min before an episode with glucose values 60 to 69 mg/dL, but only -0.39 (± 0.70) for patients who attained a glucose range of 80 to 110 mg/dL without hypoglycemia (P < .001). Glucose variability before an event progressively increased with worsening biochemical hypoglycemia and was least among patients achieving glucose concentrations in the 80 to 110-mg/dL range without hypoglycemia (P < .001).ConclusionsAntecedent glucose change and variability were greater for patients who experienced hypoglycemia. If monitored, these patterns could potentially alert clinicians and help them take preventive measures. Further examination of how these parameters interact with other predisposing risk factors for hypoglycemia is warranted. (Endocr Pract. 2012;18:317-324)
