Trial of labour following two previous caesarean sections - A UK cohort study.

OBJECTIVES: To assess the (i) predictors of and associated rates of success and; (ii) maternal and perinatal outcomes of women undergoing trial of labour after two previous caesarean sections (TOLA2C). STUDY DESIGN: This retrospective cohort study collected data from two regional obstetric centres with 12,000 deliveries per annum collectively. The population included singleton pregnancies undergoing (i) TOLA2C, (ii) elective repeat caesarean section following two caesarean sections (ERCS) and (iii) trial of labour after one caesarean section (TOLA1C). Data was collected electronically from 2013 to 2021. Statistical analysis included Fisher exact and Kruskal-Wallis test to compare unpaired samples alongside univariate and multivariable logistic regression. The primary outcome measure was maternal and perinatal outcome. RESULTS: The three groups included; n = 146 TOLA2C, n = 206 ERCS and n = 99 TOLA1C. TOLA2C had a success rate of 65 % compared to 74 % for TOLA1C (p = 0.16). The optimal predictor of successful TOLA2C was previous successful TOLA1C OR 8.65 (95 % CI 2.75-38.41). TOLA2C was associated with greater risk of endometritis and/or sepsis postnatally compared to the other two groups [10.3 % (n = 15) versus 0.5 % (n = 1) and 3 % (n = 3) for ERCS and TOLA1C respectively p < 0.01]. It was also associated with longer maternal hospital stay [2.4 days (+/-1.8) versus 1.8 (+/-0.8) and 1.8 (+/-1.7) p < 0.01], a greater proportion of neonates with Apgar scores less than 7 (p=<0.01) and higher rates of neonatal unit admission [14 % (n = 20) versus 5 % (n = 11) versus 4 % (n = 4) (p=<0.01)]. CONCLUSION: Women considering trial of labour following two caesarean sections should be counselled regarding the potential increased risk of endometritis, sepsis and adverse neonatal outcome.

Comprehensive profiling of L1 retrotransposons in mouse.

L1 elements are retrotransposons currently active in mammals. Although L1s are typically silenced in most normal tissues, elevated L1 expression is associated with a variety of conditions, including cancer, aging, infertility and neurological disease. These associations have raised interest in the mapping of human endogenous de novo L1 insertions, and a variety of methods have been developed for this purpose. Adapting these methods to mouse genomes would allow us to monitor endogenous in vivo L1 activity in controlled, experimental conditions using mouse disease models. Here, we use a modified version of transposon insertion profiling, called nanoTIPseq, to selectively enrich young mouse L1s. By linking this amplification step with nanopore sequencing, we identified >95% annotated L1s from C57BL/6 genomic DNA using only 200 000 sequencing reads. In the process, we discovered 82 unannotated L1 insertions from a single C57BL/6 genome. Most of these unannotated L1s were near repetitive sequence and were not found with short-read TIPseq. We used nanoTIPseq on individual mouse breast cancer cells and were able to identify the annotated and unannotated L1s, as well as new insertions specific to individual cells, providing proof of principle for using nanoTIPseq to interrogate retrotransposition activity at the single-cell level in vivo.

Diagnostic test accuracy of procalcitonin and C-reactive protein for predicting invasive and serious bacterial infections in young febrile infants: a systematic review and meta-analysis.

BACKGROUND: Febrile infants presenting in the first 90 days of life are at higher risk of invasive and serious bacterial infections than older children. Modern clinical practice guidelines, mostly using procalcitonin as a diagnostic biomarker, can identify infants who are at low risk and therefore suitable for tailored management. C-reactive protein, by comparison, is widely available, but whether C-reactive protein and procalcitonin have similar diagnostic accuracy is unclear. We aimed to compare the test accuracy of procalcitonin and C-reactive protein in the prediction of invasive or serious bacterial infections in febrile infants. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, EMBASE, Web of Science, and The Cochrane Library for diagnostic test accuracy studies up to June 19, 2023, using MeSH terms "procalcitonin", and "bacterial infection" or "fever" and keywords "invasive bacterial infection*" and "serious bacterial infection*", without language or date restrictions. Studies were selected by independent authors against eligibility criteria. Eligible studies included participants aged 90 days or younger presenting to hospital with a fever (≥38°C) or history of fever within the preceding 48 h. The primary index test was procalcitonin, and the secondary index test was C-reactive protein. Test kits had to be commercially available, and test samples had to be collected upon presentation to hospital. Invasive bacterial infection was defined as the presence of a bacterial pathogen in blood or cerebrospinal fluid, as detected by culture or quantitative PCR; authors' definitions of serious bacterial infection were used. Data were extracted from selected studies, and the detection of invasive or serious bacterial infections was analysed with two models for each biomarker. Diagnostic accuracy was determined against internationally recognised cutoff values (0·5 ng/mL for procalcitonin, 20 mg/L for C-reactive protein) and pooled to calculate partial area under the curve (pAUC) values for each biomarker. Optimum cutoff values were identified for each biomarker. This study is registered with PROSPERO, CRD42022293284. FINDINGS: Of 734 studies derived from the literature search, 14 studies (n=7755) were included in the meta-analysis. For the detection of invasive bacterial infections, pAUC values were greater for procalcitonin (0·72, 95% CI 0·56-0·79) than C-reactive protein (0·28, 0·17-0·61; p=0·016). Optimal cutoffs for detecting invasive bacterial infections were 0·49 ng/mL for procalcitonin and 13·12 mg/L for C-reactive protein. For the detection of serious bacterial infections, procalcitonin and C-reactive protein had similar pAUC values (0·55, 0·44-0·69 vs 0·54, 0·40-0·61; p=0·92). For serious bacterial infections, the optimal cutoffs for procalcitonin and C-reactive protein were 0·17 ng/mL and 16·18 mg/L, respectively. Heterogeneity was low for studies investigating the test accuracy of procalcitonin in detecting invasive bacterial infection (I2=23·5%), high for studies investigating procalcitonin for serious bacterial infection (I2=75·5%), and moderate for studies investigating C-reactive protein for invasive bacterial infection (I2=49·5%) and serious bacterial infection (I2=28·3%). The absence of a single definition of serious bacterial infection across studies was the greatest source of interstudy variability and potential bias. INTERPRETATION: Within a large cohort of febrile infants, a procalcitonin cutoff of 0·5 ng/mL had a superior pAUC value to a C-reactive protein cutoff of 20 mg/L for identifying invasive bacterial infections. In settings without access to procalcitonin, C-reactive protein should therefore be used cautiously for the identification of invasive bacterial infections, and a cutoff value below 20 mg/L should be considered. C-reactive protein and procalcitonin showed similar test accuracy for the identification of serious bacterial infection with internationally recognised cutoff values. This might reflect the challenges involved in confirming serious bacterial infection and the absence of a universally accepted definition of serious bacterial infection. FUNDING: None.

Dyadic Investigation of Posttraumatic Stress Symptoms and Daily Sleep Health in Patients With Cancer and Their Caregivers.

OBJECTIVE: Cancer can be a traumatic experience affecting multidimensional aspects of sleep among patients and caregivers. This study examined the differential associations of cancer-related posttraumatic stress symptoms (PTSS) with various sleep markers in this population. METHODS: Patients newly diagnosed with colorectal cancer ( n = 138, mean age = 56.93 years, 31.88% female, 60.14% Hispanic, 6.53 months after diagnosis) and their sleep-partner caregivers ( n = 138, mean age = 55.32 years, 68.12% female, 57.97% Hispanic) completed questionnaires assessing the four PTSS clusters (intrusion, avoidance, alterations in arousal and reactivity, negative alterations in cognitions and mood). Participants also completed daily sleep diaries for 14 consecutive days, from which sleep onset latency (SOL), wake after sleep onset (WASO), and sleep duration were derived. RESULTS: Actor-partner interdependence model revealed that caregivers' greater alterations in arousal and reactivity were associated with their own longer SOL ( b = 15.59, p < .001) and their patients' longer sleep duration ( b = 0.61, p = .014), whereas patients' arousal and reactivity were associated with their caregivers' shorter SOL ( b = -8.47, p = .050). Patients' and caregivers' greater negative alterations in cognitions and mood were associated with patients' longer SOL ( b = 9.15, p = .014) and shorter sleep duration ( b = -0.41, p = .050), respectively. Caregivers' greater intrusion was related to their own shorter SOL ( b = -10.14, p = .004). CONCLUSIONS: The four PTSS clusters, particularly arousal and reactivity and negative cognitions and mood, have distinct associations with sleep markers individually and dyadically in patients and caregivers affected by cancer. Investigations of psychosocial and biobehavioral pathways underlying these relations are warranted. Tailored trauma treatments and sleep interventions may improve the well-being of this population.

Correlates of posttraumatic stress in cancer patients and their family caregivers across two years following diagnosis.

OBJECTIVE: To examine risk-factors of cancer-related PTSS in the 2-years post-diagnosis in adult colorectal cancer patients and caregivers. METHODS: Patients with colorectal cancer and their caregivers (N = 130 dyads) self-reported sociodemographic, psychosocial, and medical factors at diagnosis/treatment initiation (T1), at 1- (T2), and 2-year (T3) post-diagnosis. Cancer-related PTSS were assessed, and path analysis examined associations between proposed correlates and PTSS. RESULTS: Among patients, higher neuroticism and greater physical symptom distress were concurrently associated with higher PTSS (Bs ≥ 0.10, ps ≤ 0.02); greater physical symptom distress at T1 and greater social support at T2 were associated with higher PTSS at T3 (Bs ≥ 0.37, ps ≤ 0.04). Among caregivers, female gender, higher neuroticism (Bs ≥ 0.12, ps < 0.01), and lower social support (Bs  ≤ -0.24, ps ≤ 0.02) were associated with higher concurrent PTSS; lower patient physical symptom distress and social support at T1 (Bs  ≤ -0.27, ps ≤ 0.03) and longer hours spent caregiving at T2 (B = 0.03, p = 0.05) were associated with higher PTSS at T3. CONCLUSIONS: Findings identify cancer-specific risk factors (physical symptoms, hours caregiving), in addition to established risk factors (female, neuroticism, social support) in non-medical populations. The identified subgroups should receive ongoing screening and psychosocial referral for cancer-related PTSS.

Applying clinical decision aids for the assessment and management of febrile infants presenting to emergency care in the UK and Ireland: Febrile Infant Diagnostic Assessment and Outcome (FIDO) Study protocol.

INTRODUCTION: Febrile infants 90 days and younger are at risk of invasive bacterial infections (bacteraemia and meningitis) and urinary tract infections. Together this is previously termed serious bacterial infection with an incidence of approximately 10-20%. The National Institute for Health and Care Excellence guidance advocates a cautious approach with most infants requiring septic screening, parenteral broad-spectrum antibiotics and hospital admission. Internationally, variations exist in the approach to febrile infants, with European and North American guidance advocating a tailored approach based on clinical features and biomarker testing. None of the available international clinical decision aids (CDAs) has been validated in the UK and Irish cohorts. The aim of the Febrile Infant Diagnostic Assessment and Outcome (FIDO) Study is to prospectively validate a range of CDAs in a UK and Irish population including CDAs that use procalcitonin testing. METHODS AND ANALYSIS: The FIDO Study is a prospective multicentre mixed-methods cohort study conducted in UK and Irish hospitals. All infants aged 90 days and younger presenting with fever or history of fever (≥38°C) are eligible for inclusion. Infants will receive standard emergency clinical care without delay. Clinical data and blood samples will be collected, and consent will be obtained at the earliest appropriate opportunity using research without prior consent methodology. The performance and cost-effectiveness of CDAs will be assessed. An embedded qualitative study will explore clinician and caregiver views on different approaches to care and perceptions of risk. ETHICS AND DISSEMINATION: This study was reviewed and approved by the Office for Research Ethics Committees Northern Ireland-Health and Social Care Research Ethics Committee B, Public Benefit and Privacy Panel for Health and Social Care Scotland, and Children's Health Ireland Research and Ethics Committee Ireland. The results of this study will be presented at academic conferences and in peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT05259683.

Spray dried progesterone formulations for carrier free dry powder inhalation.

Low oral absorption and extensive first pass metabolism of progesterone is reported for many oral formulations which warrants investigation into other routes of administration. It is the aim of this study to investigate the generation of inhaled formulations of progesterone though a spray drying approach with a focus on how spray drying impacts the physicochemical properties of progesterone. Formulations of progesterone with L-leucine and hydroxypropyl methylcellulose acetate succinate (HPMCAS) are reported to this aim. X-ray diffraction, spectroscopy and thermal analysis were used to characterise these formulations and confirmed that progesterone crystallises as the Form II polymorph during spray drying regardless of the solvent used. The resultant formulations showed higher aqueous solubility than progesterone Form I starting material and the addition of HPMCAS was shown to temporarily enable a supersaturated state. Thermal analysis was used to show that the Form II polymorph was sensitive to transformation to Form I during heating. The addition of L-leucine to the formulations reduced the temperature for the polymorphic transformation by âˆ¼ 10 °C. However, when HPMCAS was added to the formulation, the Form II polymorph was prevented from transforming to the Form I polymorph. Cascade impaction was used to determine the aerosol performance of the spray dried powders and showed promising lung deposition profiles (mass median aerodynamic diameter 5 µm) with significant variation depending on the organic solvent used and the ratio of organic to aqueous phase in the feedstock. However, further optimisation of formulations was required to direct more progesterone into the alveolar regions. The addition of HPMCAS was seen to increase the alveolar deposition and therefore formed a formulation with a lower fine particle fraction and mass median aerodynamic diameter. The most suitable formulation for inhalation was formed from a 50:50 acetone:water mixture and showed an ED, FPF and FPD of 81.7%, 44.5% and 7.3 mg respectively. Therefore, HPMCAS is suggested as a suitable excipient to increase solubility, prevent polymorphic transformation and improve inhalation properties of spray dried progesterone formulations. This study highlights the use of spray drying to form inhalable progesterone powders with higher solubility which may broaden the application of this medicine.

Motives for nonmedical use of prescription stimulants in community college students.

Objective: The present study identified common motives for nonmedical use of prescription stimulants (NMUS) among community college (CC) students and examined behavioral and demographic correlates of certain motives. Participants: The survey was completed by 3,113 CC students (72.4% female; 81.7% White). Methods: Survey results from 10 CCs were evaluated. Results: NMUS was reported by 9% (n = 269) participants. The most common motive for NMUS was to "focus on studies or to improve academic performance" (67.5%) followed by to "have more energy" (52.4%). Females were more likely to report NMUS for weight loss, and males were more likely to report NMUS to experiment. The motive "to feel good or get high" was linked to polysubstance use. Conclusions: CC students report similar motives for NMUS to those commonly endorsed by 4-year university students. These findings may help identify CC students susceptible to risky substance use.

Open Surgery for Abdominal Aortic Aneurysm: 980 Consecutive Patient Outcomes from a High-Volume Centre in the United Kingdom.

BACKGROUND: Controversy persists regarding the optimal treatment for large abdominal aortic aneurysm (AAA), highlighted by the publication of the National Institute for Health and Care Excellence (NICE) guideline (NG156) on March 2020. The pendulum of opinion swings once more from endovascular to open surgical treatment. We report our experience over the last 15 years in treating consecutive AAA by open surgery. METHODS: A retrospective review of a prospectively collected vascular database of all patients undergoing infra-renal open abdominal aortic aneurysm repair (OR) repair from 2004 to 2019 at the largest aneurysm centre in the United Kingdom. OR for elective and emergency (ruptured and symptomatic) outcomes included early morbidity and 30-day mortality, and long-term survival. RESULTS: 1017 patients underwent OR between 2004-2019, on application of our inclusion-criteria 994 patients formed our cohort for analysis (81.2% male) with a mean age 73.6 ± 7.8 years treated by OR for AAA. In that group 672 were elective and 308 were emergency (for ruptured or symptomatic). Overall 30 day mortality was 11.3%, elective 30 day mortality was 2.5%, and emergency 30 day mortality was 29.9%. 30 day re-intervention rate was 9.5%, (elective 7.0%, emergency 15.9%). Survival at 1000 days for elective repair was 72 v 46.7% for emergency and at 2000 days was 43.4% for elective v 25% for emergency. CONCLUSION: Our data confirm that open surgery for AAA can be performed in large volume centres quite safely. Elective and Emergency surgery does affect early 30 day mortality but does not influence long-term outcome.

Mid-Arm Point in PAEDiatrics (MAPPAED): An effective procedural aid for safe pleural decompression in trauma.

OBJECTIVE: Life-threatening thoracic trauma requires emergency pleural decompression and thoracostomy and chest drain insertion are core trauma procedures. Reliably determining a safe site for pleural decompression in children can be challenging. We assessed whether the Mid-Arm Point (MAP) technique, a procedural aid proposed for use with injured adults, would also identify a safe site for pleural decompression in children. METHODS: Children (0-18 years) attending four EDs were prospectively recruited. The MAP technique was performed, and chest wall skin marked bilaterally at the level of the MAP; no pleural decompression was performed. Radio-opaque markers were placed over the MAP-determined skin marks and corresponding intercostal space (ICS) reported using chest X-ray. RESULTS: A total of 392 children participated, and 712 markers sited using the MAP technique were analysed. Eighty-three percentage of markers were sited within the 'safe zone' for pleural decompression (4th to 6th ICSs). When sited outside the 'safe zone', MAP-determined markers were typically too caudal. However, if the site for pleural decompression was transposed one ICS cranially in children ≥4 years, the MAP technique performance improved significantly with 91% within the 'safe zone'. CONCLUSIONS: The MAP technique reliably determines a safe site for pleural decompression in children, albeit with an age-based adjustment, the Mid-Arm Point in PAEDiatrics (MAPPAED) rule: 'in children aged ≥4 years, use the MAP and go up one ICS to hit the safe zone. In children <4 years, use the MAP.' When together with this rule, the MAP technique will identify a site within the 'safe zone' in 9 out of 10 children.

Prevalence of gender dysphoria and suicidality and self-harm in a national database of paediatric inpatients in the USA: a population-based, serial cross-sectional study.

BACKGROUND: Transgender and non-binary young people experience discrimination that has been linked to suicidal ideation and self-harm, but few studies have examined this association systematically. We aimed to study the association between gender dysphoria-related diagnostic coding and hospital admission for suicidality or self-harm in a large representative pediatric inpatient database from the USA. METHODS: Using the 2016 and 2019 Kids' Inpatient Database (KID), we identified transgender and non-binary young people (aged 6-20 years) with International Classification of Diseases (ICD)-10 codes related to gender dysphoria. We identified suicidal ideation using explicit suicidality ICD-10 codes, and self-harm using 355 self-harm ICD-10 codes. Prevalence of suicidality (primary outcome), self-harm, and the combination of suicidality and self-harm (secondary outcomes) was compared between young people with and without gender dysphoria-related codes. Univariable and multivariable regression was used to test for an association between gender dysphoria and suicidality, self-harm, or suicidality and self-harm combined. FINDINGS: 1 090 544 individuals were included from KID 2016 and 1 026 752 from KID 2019. Gender dysphoria-related diagnoses were prevalent in 161 per 100 000 hospital admissions in KID 2016 and 475 per 100 000 hospital admissions in KID 2019. In KID 2016 and KID 2019, among individuals who were White, privately insured, or from higher median income ZIP code areas, proportionately more had gender dysphoria-related codes. Prevalence of suicidality was greater in individuals with gender dysphoria-related codes than in individuals without gender dysphoria-related codes in KID 2016 (635 [36%] of 1755 individuals with gender dysphoria-related codes vs 55 351 [5%] of 1 088 789 individuals without gender dysphoria-related codes; unadjusted prevalence ratio [PR] 7·19 [95% CI 6·75-7·66]) and KID 2019 (2680 [55%] of 4872 individuals with gender dysphoria-related codes vs 38 831 [4%] of 1 021 880 individuals without gender dysphoria-related codes; unadjusted PR 5·45 [5·30-5·60]). This association persisted in multivariable modelling adjusting for confounders in KID 2016 (adjusted PR 5·02 [95% CI 4·67-5·41]) and KID 2019 (4·14 [4·02-4·28]). Increased unadjusted and adjusted PRs for individuals with gender dysphoria-related codes, relative to those without, were also evident for self-harm and when combining suicidality and self-harm in both the 2016 and 2019 datasets. INTERPRETATION: In a large representative national sample, transgender and non-binary young people with gender dysphoria-related diagnoses were frequently admitted to hospital for suicidality or self-harm. The lower rates of gender-dysphoria-related codes among young people who were non-White, publicly insured, and from low-income households suggest that underlying inequities might shape the identification and management of gender dysphoria. Structural and health-care provider-level interventions are needed to reduce discrimination and expand gender-affirming competencies to prevent adverse outcomes for hospitalised transgender and non-binary young people with gender dysphoria.

Challenges and positive impact of rare cancer caregiving: A mixed-methods study of caregivers of patients with Erdheim-Chester disease and other histiocytic neoplasms.

Background: The importance of deriving benefit and meaning has been identified among cancer caregivers, but this has yet to be examined in the context of rare cancers. We sought to characterize unmet needs and experiences of caregivers of patients with Erdheim-Chester disease (ECD) and other histiocytic neoplasms (HN) and to identify factors associated with finding benefit and meaning-making in providing care for patients with rare cancers. Methods: Caregivers of patients with ECD and other HN completed quantitative surveys. Linear univariable regression modeling examined associations between unmet needs, social and family support, and intolerance of uncertainty with benefit finding and meaning-making. A subset participated in qualitative interviews assessing experiences of rare cancer caregiving that were analyzed with applied thematic analysis (NCT039900428). Findings: Of caregivers (N = 92, M = 54 years old, 68% female) of patients with ECD (75%) and other HN (25%), 78% reported moderately or severely unmet support needs, most frequently informational (58%) and psychological/emotional (66%) needs. Caregivers with unmet informational, psychological/emotional, and social support needs, difficulty tolerating uncertainty, a longer duration of the patient's illness, lower social support, more family conflict, and higher anxiety and depression symptoms demonstrated less benefit finding and meaning-making (ps <.05). Qualitative interviews (N = 19) underscored information and support needs and the capacity to derive meaning from caregiving. Interpretation: Rare cancer caregivers report numerous unmet information and support needs, needs that arise from disease rarity itself and which are associated with diminished capacity for deriving benefit and meaning from caregiving. Findings highlight targets for interventions to improve support for caregivers with HN and other rare cancers.

Pilot Trial of Homebound Hematopoietic Cell Transplantation.

For eligible patients with multiple myeloma (MM) and amyloid light chain (AL) amyloidosis, high-dose chemotherapy and autologous hematopoietic cell transplantation (HCT) is a standard and widely used consolidation therapy. Autologous HCT requires specialized care at a transplantation center and investment from patients and caregivers. We studied the safety and feasibility of delivering transplantation care in a homebound setting to decrease the burden of therapy and increase access to autologous HCT. Patients with MM and AL amyloidosis undergoing autologous HCT were eligible if they resided in designated ZIP codes and had a full-time caregiver, Wi-Fi connection, HCT Comorbidity Index ≤3, and Karnofsky Performance Status score ≥80. High-dose melphalan (on day -2) and hematopoietic cell reinfusion (day 0) were administered in the outpatient clinic. Protocol-specific home care was provided from day +1 through engraftment. Patients were assessed and blood was drawn daily by advanced practice providers. Interventions were delivered by registered nurses. Attending physicians communicated daily through telemedicine. Quality of life, patient and caregiver satisfaction, and fecal microbiota profiling data were collected. Fifteen patients were enrolled and received transplantation care at home starting on day +1 following hematopoietic cell infusion. Patients remained in the program for an average of 12 days and required an average of 2 outpatient visits while receiving home care. Seven of 15 patients were admitted for a median of 4 days (range, 3 to 10 days); admission occurred on day +7 in 5 patients, on day +8 in 1 patient, and on day +12 in 1 patient for neutropenic fever in 2 patients, fever attributed to engraftment syndrome in 2 patients, diarrhea in 2 patients, and dehydration in 1 patient. Only 1 patient had a documented infection (Clostridioides difficile). One patient admitted with neutropenic fever required intensive care unit admission for a gastrointestinal bleed. Forty-seven percent of the patients experienced a grade ≥3 nonhematologic toxicity. There were no deaths on the study. Patients and caregivers reported high satisfaction with care. Microbiota diversity patterns were similar to those of autologous HCT recipients who did not receive post-HCT care at home, although a subset of the cohort maintained microbiota diversity throughout. Homebound HCT in an urban setting is safe and feasible, with less than one-half of patients requiring inpatient admission. Despite increased patient and caregiver responsibility in the homebound setting compared with an inpatient setting, patient and caregiver satisfaction was high. These results support expansion of homebound transplantation care programs.

Systematic review and meta-analysis assessing the diagnostic test accuracy of procalcitonin in the diagnosis of invasive bacterial infections in febrile infants: a study protocol.

INTRODUCTION: Young febrile infants are at higher risk of invasive bacterial infections (IBIs) compared with older children. The clinical features of IBI are subtle in this cohort mandating that clinicians take a cautious approach to their initial assessment and management. This includes the measurement of blood biomarkers of infection such as C reactive protein (CRP) and procalcitonin (PCT). In the UK, PCT is not widely available and not recommended for routine use in hospital. This is in contrast to Europe and the USA where PCT is regularly used to assist clinical decision-making. The objective of this review and meta-analysis is to report the diagnostic test accuracy of PCT in detecting IBI in febrile infants less than 91 days old, compare its accuracy with CRP and define optimal PCT cut-off values in this cohort. METHODS AND ANALYSIS: A search strategy will include MEDLINE, EMBASE, Web of Science, The Cochrane Library and grey literature. There will be no language or date limitations. Diagnostic accuracy studies compliant with STARD criteria will be considered against eligibility criteria. Abstracts, then full texts, of potentially eligible studies will be independently screened for selection. Data extraction and quality assessment, using the QUADAS-2 tool, will be completed by two independent authors and a third author used for any inconsistencies. True positives, false positives, true negatives and false negatives will be pooled to collate specificity and sensitivity with 95% CIs. Results will be portrayed in forest plots, alongside their quality assessments. ETHICS AND DISSEMINATION: This review does not require ethical clearance. This review will be published in peer-reviewed journals and key messages will be disseminated through presentations at local and international conferences related to this field. The authors aim for this review to be completed and published in 2023.

Diagnostic test accuracy of dipstick urinalysis for diagnosing urinary tract infection in febrile infants attending the emergency department.

OBJECTIVE: To report the diagnostic test accuracy of dipstick urinalysis for the detection of urinary tract infections (UTIs) in febrile infants aged 90 days or less attending the emergency department (ED). DESIGN: Retrospective cohort study. PATIENTS: Febrile infants aged 90 days or less attending between 31 August 2018 and 1 September 2019. MAIN OUTCOME MEASURES: The sensitivity, specificity and predictive values of dipstick urinalysis in detecting UTIs defined as growth of ≥100 000 cfu/mL of a single organism and the presence of pyuria (>5 white blood cells per high-power field). SETTING: Eight paediatric EDs in the UK/Ireland. RESULTS: A total of 275 were included in the final analysis. There were 252 (92%) clean-catch urine samples and 23 (8%) were transurethral bladder catheter samples. The median age was 51 days (IQR 35-68.5, range 1-90), and there were 151/275 male participants (54.9%). In total, 38 (13.8%) participants had a confirmed UTI. The most sensitive individual dipstick test for UTI was the presence of leucocytes. Including 'trace' as positive resulted in a sensitivity of 0.87 (95% CI 0.69 to 0.94) and a specificity of 0.73 (95% CI 0.67 to 0.79). The most specific individual dipstick test for UTI was the presence of nitrites. Including trace as positive resulted in a specificity of 0.91 (95% CI 0.86 to 0.94) and a sensitivity of 0.42 (95% CI 0.26 to 0.59). CONCLUSION: Point-of-care urinalysis is moderately sensitive and highly specific for diagnosing UTI in febrile infants. The optimum cut-point to for excluding UTI was leucocytes (1+), and the optimum cut-point for confirming UTI was nitrites (trace). TRIAL REGISTRATION NUMBER: NCT04196192.

Nursing Faculty's Perceptions of Climate Change and Sustainability.

AIM: The aim of this research study was to investigate the perceptions of climate change and sustainability of faculty teaching in associate and baccalaureate degree nursing programs in South Carolina and their attitudes toward inclusion of relevant content into the nursing curriculum. BACKGROUND: Climate change is a topic that receives limited discussion in most nursing education curricula. METHOD: This cross-sectional, descriptive study gathered data from 21 schools of nursing via an online survey consisting of demographic questions, the New Ecological Paradigm Scale, and the Sustainability Attitudes in Nursing Survey 2 and two questions regarding the current inclusion of content. RESULTS: Eighty-one percent of respondents did not include health implications of climate change in their teaching content; 67% did not include health implications of sustainability. CONCLUSION: Results provide preliminary evidence of gaps and areas of need for curricular content related to climate change and sustainability.

Use of mechanical insufflation exsufflation and manual techniques in an intubated adult with COVID-19 positioned in prone-A case study.

BACKGROUND AND PURPOSE: The therapeutic benefits of prone positioning have been described over the last 50 years culminating in a systematic review supporting this management strategy for patients with severe hypoxaemic respiratory failure. Early work detailing treatment approaches for COVID-19 have advocated the use of prone positioning. Limited data exists regarding physiotherapy intervention in patients with COVID-19 owing to the recent emergence of this novel disease. Despite the acknowledged beneficial effects of physiotherapy on secretion clearance and lung recruitment in the general critical care population, there is a lack of evidence pertaining to physiotherapeutic intervention for acutely unwell intubated adults in prone lying. METHODS: This case study report follows the CARE case report guidelines. One patient with COVID-19 pneumonitis who underwent physiotherapy intervention in prone lying is discussed. Informed consent was gained from next of kin for data to be published. RESULTS: Treatment techniques including mechanical insufflation-exsufflation in prone were feasible and well tolerated by this patient with only transient adverse effects noted. Treatment techniques assisted with secretion clearance. DISCUSSION: Further work on safety, feasibility, and efficacy of physiotherapy intervention in patients with and without COVID-19 in prone will contribute to the evidence base on this subject.
