Examining the validity and reliability of the COMcareSS (Continuity of Midwifery Care Satisfaction Survey).

BACKGROUND: Continuity of midwifery care has been proven to show an improvement in clinical outcomes for women and greater maternal satisfaction with maternity care. Several questionnaires have been developed to measure satisfaction with maternity services although few are suitable for continuity of midwifery maternity care models, and many have not been validated. AIMS: The purpose of this study was to test the reliability and validity of the newly developed Continuity of Midwifery Care Satisfaction Survey (COMcareSS) with a cohort of women who have recently experienced continuity of midwifery care. METHODS: The COMcareSS was distributed to women in Australia who had experienced a live birth within a continuity model of midwifery care and were up to two months postpartum. Factor analysis was conducted, and Cronbach's alpha coefficient calculated for the 34-item scale. FINDINGS: In total 272 completed responses were recorded. Cronbach's alpha coefficient for the scale was 0.96 suggesting some redundancy in items. There was a lack of variation in responses. In factor analysis, only one factor could feasibly be attempted. This accounted for 76 % of variation in responses. CONCLUSION: The COMcareSS scale is the first to be developed to measure maternal satisfaction with continuity of midwifery led care. The 34-item scale has good internal consistency. The scale may be unidimensional though the lack of variation in responses means that other possible latent constructs, were not able to be detected. Use of a standardised scale such as the COMcareSS will facilitate benchmarking between services and, comparison and meta-analysis in research studies.

Raspberry leaf (Rubus idaeus) use in pregnancy: a prospective observational study.

BACKGROUND: Raspberry leaf use during pregnancy in Australia is widespread. There has been little research exploring the potential beneficial or harmful effects of raspberry leaf on pregnancy, labour, and birth. More research is needed to appropriately inform childbearing women and maternity healthcare professionals on the effects of raspberry leaf so that women can make informed choices. METHODS: This study aimed to determine associations between raspberry leaf use in pregnancy and augmentation of labour and other secondary outcomes. Data was derived from questionnaires which captured demographic information and herbal use in pregnancy. Clinical outcomes were accessed from the maternity services' clinical database. Data analysis was conducted in R via package 'brms' an implementation for Bayesian regression models. RESULTS: A total of 91 completed records were obtained, 44 exposed to raspberry leaf and 47, not exposed. A smaller proportion of women in the raspberry leaf cohort had augmentation of labour, epidural anaesthesia, instrumental births, caesarean section, and postpartum haemorrhage. A larger proportion had vaginal birth and length of all phases of labour were shorter. Under these conditions the use of raspberry leaf was strongly predictive of women not having their labours medically augmented. CONCLUSIONS: While our study demonstrated that raspberry leaf was strongly predictive of women not having their labours medically augmented, the results cannot be relied on or generalised to the wider population of pregnant women. While there were no safety concerns observed in our study, this should not be taken as evidence that raspberry leaf is safe. A randomised controlled trial is urgently needed to provide women and healthcare providers with robust evidence on which to base practice.

Predicting cytopenias, progression, and survival in patients with clonal cytopenia of undetermined significance: a prospective cohort study.

BACKGROUND: Somatic mutations are frequently reported in individuals with cytopenia but without a confirmed haematological diagnosis (clonal cytopenia of undetermined significance; CCUS). These patients have an increased risk of progression to a myeloid malignancy and worse overall survival than those with no such mutations. To date, studies have been limited by retrospective analysis or small patient numbers. We aimed to establish the natural history of CCUS by prospectively investigating outcome in a large, well defined patient cohort. METHODS: This prospective cohort study was conducted at the Haematological Malignancy Diagnostic Service, a diagnostic laboratory in Leeds, UK. Patients aged at least 18 years who were referred for investigation of cytopenia were eligible for inclusion; those with a history of myeloid malignancy were not eligible. Targeted sequencing was conducted alongside routine clinical testing. Baseline mutation analysis was then correlated with the main study outcomes: longitudinal blood counts, disease progression to a myeloid malignancy, and overall survival with a median follow-up of 4·54 years (IQR 4·03-5·04). Data were collected manually from hospital records or extracted from laboratory or clinical outcome databases. FINDINGS: Bone marrow samples from 2348 patients were received at the Haematological Malignancy Diagnostic Service between July 1, 2014, and July 31, 2016. Of these, 2083 patients (median age 72 years [IQR 63-80, range 18-99]; 854 [41·0%] female and 1229 [59·0%] male) met the inclusion criteria and had samples of sufficient quality for further analysis. 598 (28·7%) patients received a diagnosis on the basis of their biopsy sample, whereas 1485 (71·3%) samples were classified as non-diagnostic; of these, CCUS was confirmed in 400 (26·9%) patients (256 [64·0%] male and 144 [36·0%] female). TET2, SRSF2, and DNMT3A were the most frequently mutated genes in patients with CCUS, with 320 (80%) of 400 patients harbouring a mutation in at least one of these genes. Age (p<0·0001), sex (p=0·0027), and mutations in ASXL1 (p=0·0009), BCOR (p=0·0056), and TP53 (p=0·0055) correlated with a worse overall survival; however, the number of mutations was the strongest predictor for progression to a myeloid malignancy (two mutations, p=0·0024; three or more mutations, p=0·0004). Extended sequencing of samples from a subgroup of patients with sequential samples and no mutations in the initial myeloid gene panel showed recurrent mutations in both DDX41 and UBA1, suggesting that these genes should be included in clinical test panels. INTERPRETATION: Mutation analysis is advised in patients who have undergone bone marrow examination and have an otherwise-unexplained cytopenia. High-risk genetic mutations and increased numbers of mutations are predictive of both survival and progression within 5 years of presentation, warranting clinical surveillance and, when necessary, intervention.

Association of continuity of carer and women's experiences of maternity care during the COVID-19 pandemic: A cross-sectional survey.

BACKGROUND: Recent research highlights the impact of the COVID-19 pandemic on maternity services, although none to date have analysed the association between continuity of carer and how women felt about the changes to pregnancy care and birth plans. AIM: To describe pregnant women's self-reported changes to their planned pregnancy care and associations between continuity of carer and how women feel about changes to their planned care. METHODS: A cross-sectional online survey of pregnant women aged over 18 years in their final trimester of pregnancy in Australia. FINDINGS: 1668 women completed the survey. Most women reported at least one change to pregnancy care and birthing plans. Women receiving full continuity of carer were more likely to rate the changes to care as neutral/positive (p<.001) when compared with women who received partial or no continuity. DISCUSSION: Pregnant women experienced many changes to their planned pregnancy and birth care during the COVID-19 pandemic. Women who received full continuity of carer experienced fewer changes to care and were more likely to feel neutral/positive about the changes than women who did not receive full continuity of carer.

Incidence, characteristics, risk factors and outcomes of diabetic ketoacidosis in COVID-19 patients: Comparison with influenza and pre-pandemic data.

AIMS: This study characterized incidence, patient profiles, risk factors and outcomes of in-hospital diabetic ketoacidosis (DKA) in patients with COVID-19 compared with influenza and pre-pandemic data. METHODS: This study consisted of 13 383 hospitalized patients with COVID-19 (March 2020-July 2022), 19 165 hospitalized patients with influenza (January 2018-July 2022) and 35 000 randomly sampled hospitalized pre-pandemic patients (January 2017-December 2019) in Montefiore Health System, Bronx, NY, USA. Primary outcomes were incidence of in-hospital DKA, in-hospital mortality, and insulin use at 3 and 6 months post-infection. Risk factors for developing DKA were identified. RESULTS: The overall incidence of DKA in patients with COVID-19 and influenza, and pre-pandemic were 2.1%, 1.4% and 0.5%, respectively (p < .05 pairwise). Patients with COVID-19 with DKA had worse acute outcomes (p < .05) and higher incidence of new insulin treatment 3 and 6 months post-infection compared with patients with influenza with DKA (p < .05). The incidence of DKA in patients with COVID-19 was highest among patients with type 1 diabetes (12.8%), followed by patients with insulin-dependent type 2 diabetes (T2D; 5.2%), non-insulin dependent T2D (2.3%) and, lastly, patients without T2D (1.3%). Patients with COVID-19 with DKA had worse disease severity and higher mortality [odds ratio = 6.178 (4.428-8.590), p < .0001] compared with those without DKA. Type 1 diabetes, steroid therapy for COVID-19, COVID-19 status, black race and male gender were associated with increased risk of DKA. CONCLUSIONS: The incidence of DKA was higher in COVID-19 cohort compared to the influenza and pre-pandemic cohort. Patients with COVID-19 with DKA had worse outcomes compared with those without. Many COVID-19 survivors who developed DKA during hospitalization became insulin dependent. Identification of risk factors for DKA and new insulin-dependency could enable careful monitoring and timely intervention.

COVID-19 associated ketosis and diabetic ketoacidosis: A rapid review.

SARS-CoV-2 infection could disrupt the endocrine system directly or indirectly, which could result in endocrine dysfunction and glycaemic dysregulation, triggering transient or persistent diabetes mellitus. The literature on the complex relationship between COVID-19 and endocrine dysfunctions is still evolving and remains incompletely understood. Thus, we conducted a review on all literature to date involving COVID-19 associated ketosis or diabetic ketoacidosis (DKA). In total, 27 publications were included and analysed quantitatively and qualitatively. Studies included patients with DKA with existing or new onset diabetes. While the number of case and cohort studies was limited, DKA in the setting of COVID-19 seemed to increase risk of death, particularly in patients with new onset diabetes. Future studies with more specific variables and larger sample sizes are needed to draw better conclusions.

Fifty years of data show the effects of climate on overall skull size and the extent of seasonal reversible skull size changes (Dehnel's phenomenon) in the common shrew.

Global climate change affects many aspects of biology and has been shown to cause body size changes in animals. However, suitable datasets allowing the analysis of long-term relationships between body size, climate, and its effects are rare. The size of the skull is often used as a proxy for overall body size. Skull size does not change much in fully grown vertebrates; however, some high-metabolic small mammals shrink in winter and regrow in spring, including their skull and brain. This is thought to be a winter adaptation, as a smaller brain size reduces energy requirements. Climate could thus affect not only the overall size but also the pattern of the size change, that is, Dehnel's phenomenon, in these animals. We assessed the impact of the changes in climate on the overall skull size and the different stages of Dehnel's phenomenon in skulls of the common shrew, Sorex araneus, collected over 50 years in the Bialowieza Forest, E Poland. Overall skull size decreased, along with increasing temperatures and decreasing soil moisture, which affected the availability of the shrews' main food source, earthworms. The skulls of males were larger than those of females, but the degree of the decrease in size did not differ between sexes. The magnitude of Dehnel's phenomenon increased over time, indicating an increasing selection pressure on animals in winter. Overall, climate clearly affected the common shrew's overall size as well as its seasonal size changes. With the current acceleration in climate change, the effects on the populations of this cold-adapted species may be quite severe in a large part of its distribution range.

Quantifying the Financial Impact of Delayed Adoption of CPT Code Changes in Radiology.

PURPOSE: To quantify the financial effect of delayed reporting of new moderate sedation (MS) Current Procedural Terminology (CPT) codes at an academic radiology practice, and to identify barriers to timely reporting. MATERIALS AND METHODS: Billing and reimbursement data was collected for a 28-month period (January 1, 2017-April 30, 2019). Reporting of new MS codes was identified and compared to the number of procedures performed by radiology over the study period. Using the number of procedures performed and payment data, losses were estimated. A root cause analysis was then performed to further understand delayed reporting. RESULTS: MS was reported with 2.5% of cases in 2017, 47.8% of cases in 2018 and 69.1% of cases in 2019. Appropriate coding was not achieved until June 2018, equating to a 17-month lag in implementation. Lost revenue from inaccurate reporting of MS alone was $21,357 ± $3,945 per month. Primary barriers to an efficient transition included (1) updating billing systems, (2-5) coder, nursing, technologist, and operator education and coordination, and (6) drafting and vetting new procedural report templates. CONCLUSIONS: Delayed reporting of the new moderate sedation codes resulted in a $363,069 ± $67,065 loss of procedural revenue at an academic radiology practice. Primary drivers of the delay were lags in education and coordination at multiple points in the reporting chain. As healthcare policy shifts and changes to coding become more frequent and significant, timely adoption becomes more salient for radiologists.

Midwives providing woman-centred care during the COVID-19 pandemic in Australia: A national qualitative study.

BACKGROUND: The COVID-19 pandemic has caused isolation, fear, and impacted on maternal healthcare provision. AIM: To explore midwives' experiences about how COVID-19 impacted their ability to provide woman-centred care, and what lessons they have learnt as a result of the mandated government and hospital restrictions (such as social distancing) during the care of the woman and her family. METHODS: A qualitative interpretive descriptive study was conducted. Twenty-six midwives working in all models of care in all states and territories of Australia were recruited through social media, and selected using a maximum variation sampling approach. Data were collected through in-depth interviews between May to August, 2020. The interviews were recorded, transcribed verbatim, and thematically analysed. FINDINGS: Two overarching themes were identified: 'COVID-19 causing chaos' and 'keeping the woman at the centre of care'. The 'COVID-19 causing chaos' theme included three sub-themes: 'quickly evolving situation', 'challenging to provide care', and 'affecting women and families'. The 'Keeping the woman at the centre of care' theme included three sub-themes: 'trying to keep it normal', 'bending the rules and pushing the boundaries', and 'quality time for the woman, baby, and family unit'. CONCLUSION: Findings of this study offer important evidence regarding the impact of the pandemic on the provision of woman-centred care which is key to midwifery philosophy. Recommendations are made for ways to preserve and further enhance woman-centred care during periods of uncertainty such as during a pandemic or other health crises.

A partial migrant relies upon a range-wide cue set but uses population-specific weighting for migratory timing.

BACKGROUND: Many birds species range over vast geographic regions and migrate seasonally between their breeding and overwintering sites. Deciding when to depart for migration is one of the most consequential life-history decisions an individual may make. However, it is still not fully understood which environmental cues are used to time the onset of migration and to what extent their relative importance differs across a range of migratory strategies. We focus on departure decisions of a songbird, the Eurasian blackbird Turdus merula, in which selected Russian and Polish populations are full migrants which travel relatively long-distances, whereas Finnish and German populations exhibit partial migration with shorter migration distances. METHODS: We used telemetry data from the four populations (610 individuals) to determine which environmental cues individuals from each population use to initiate their autumn migration. RESULTS: When departing, individuals in all populations selected nights with high atmospheric pressure and minimal cloud cover. Fully migratory populations departed earlier in autumn, at longer day length, at higher ambient temperatures, and during nights with higher relative atmospheric pressure and more supportive winds than partial migrants; however, they did not depart in higher synchrony. Thus, while all studied populations used the same environmental cues, they used population-specific and locally tuned thresholds to determine the day of departure. CONCLUSIONS: Our data support the idea that migratory timing is controlled by general, species-wide mechanisms, but fine-tuned thresholds in response to local conditions.

Geographic patterns in seasonal changes of body mass, skull, and brain size of common shrews.

Some small mammals exhibit Dehnel's Phenomenon, a drastic decrease in body mass, braincase, and brain size from summer to winter, followed by a regrowth in spring. This is accompanied by a re-organization of the brain and changes in other organs. The evolutionary link between these changes and seasonality remains unclear, although the intensity of change varies between locations as the phenomenon is thought to lead to energy savings during winter.Here we explored geographic variation of the intensity of Dehnel's Phenomenon in Sorex araneus. We compiled literature on seasonal changes in braincase size, brain, and body mass, supplemented by our own data from Poland, Germany, and Czech Republic.We analyzed the effect of geographic and climate variables on the intensity of change and patterns of brain re-organization.From summer to winter, the braincase height decreased by 13%, followed by 10% regrowth in spring. For body mass, the changes were -21%/+82%, respectively. Changes increased toward northeast. Several climate variables were correlated with these transformations, confirming a link of the intensity of the changes with environmental conditions. This relationship differed for the decrease versus regrowth, suggesting that they may have evolved under different selective pressures.We found no geographic trends explaining variability in the brain mass changes although they were similar (-21%/+10%) to those of the braincase size. Underlying patterns of change in brain organization in northeastern Poland were almost identical to the pattern observed in southern Germany. This indicates that local habitat characteristics may play a more important role in determining brain structure than broad scale geographic conditions.We discuss the techniques and criteria used for studying this phenomenon, as well as its potential presence in other taxa and the importance of distinguishing it from other kinds of seasonal variation.

Somatic Mutations and the Risk of Undifferentiated Autoinflammatory Disease in MDS: An Under-Recognized but Prognostically Important Complication.

Objectives: We theorized that myelodysplastic syndrome (MDS) with somatic mutations and karyotype abnormalities are associated with autoinflammation, and that the presence of autoinflammatory disease affected prognosis in MDS. Methods: One hundred thirty-four MDS patients were assessed for the prevalence of autoinflammatory complications and its link with karyotypes and somatic mutation status. Autoinflammatory complications were described either as well-defined autoinflammatory diseases (AD) or undifferentiated "autoinflammatory disease" (UAD) (defined as CRP over 10.0 mg/L on five consecutive occasions, taken at separate times and not explained by infection). Several patient characteristics including demographic, clinical, laboratory, cytogenetics charts, and outcomes, were compared between different groups. Results: Sixty-two (46.3%) patients had an autoinflammatory complication manifesting as arthralgia (43.5% vs. 23.6%, p = 0.0146), arthritis (30.6% vs. 15.3%, p = 0.0340), skin rash (27.4% vs. 12.5%, p = 0.0301), pleuritis (14.5% vs. 4.2%, p = 0.0371) and unexplained fever (27.4% vs. 0%, p < 0.0001). AD were found in 7.4% of MDS patients (with polymyalgia rheumatic being the most frequently one). Classical autoimmune diseases were found only in 4 MDS patients (3.0%). Transcription factor pathway mutations (RUNX1, BCOR, WTI, TP53) (OR 2.20 [95%CI 1.02-4.75], p = 0.0451) and abnormal karyotypes (OR 2.76 [95%CI 1.22-6.26], p = 0.0153) were associated with autoinflammatory complications. Acute leukaemic transformation was more frequent in MDS patients with autoinflammatory features than those without (27.4% vs. 9.7%, p = 0.0080). Conclusions: Autoinflammatory complications are common in MDS. Somatic mutations of transcription factor pathways and abnormal karyotypes are associated with greater risk of autoinflammatory complications, which are themselves linked to malignant transformation and a worse prognosis.

Biophysical effects, safety and efficacy of raspberry leaf use in pregnancy: a systematic integrative review.

BACKGROUND: Childbearing women have been using various herbs to assist with pregnancy, labour and birth for centuries. One of the most common is raspberry leaf. The evidence base for the use of raspberry leaf is however under-developed. It is incumbent on midwives and other maternity care providers to provide women with evidence-based information so they can make informed choices. The aim of this study was to review the research literature to identify the evidence base on the biophysical effects, safety and efficacy of raspberry leaf in pregnancy. METHODS: A systematic, integrative review was undertaken. Six databases were searched to identify empirical research papers published in peer reviewed journals including in vitro, in vivo, human and animal studies. The search included the databases CINAHL, MEDLINE, Cochrane Library, Scopus and Web of Science Core Collection and AMED. Identified studies were appraised independently by two reviewers using the MMAT appraisal instrument. An integrative approach was taken to analysis. RESULTS: Thirteen studies were included. Five were laboratory studies using animal and human tissue, two were experiments using animals, and six were human studies. Included studies were published between 1941 and 2016. Raspberry leaf has been shown to have biophysical effects on animal and human smooth muscle including the uterus. Toxity was demonstrated when high doses were administered intravenously or intaperitoneally in animal studies. Human studies have not shown any harm or benefit though one study demonstrated a clinically meaningful (though non-statistically significant) reduction in length of second stage and augmentation of labour in women taking raspberry leaf. CONCLUSIONS: Many women use raspberry leaf in pregnancy to facilitate labour and birth. The evidence base supporting the use of raspeberry leaf in pregnancy is weak and further research is needed to address the question of raspberry leaf's effectiveness.

Comparative analysis of gene expression platforms for cell-of-origin classification of diffuse large B-cell lymphoma shows high concordance.

Cell-of-origin subclassification of diffuse large B cell lymphoma (DLBCL) into activated B cell-like (ABC), germinal centre B cell-like (GCB) and unclassified (UNC) or type III by gene expression profiling is recommended in the latest update of the World Health Organization's classification of lymphoid neoplasms. There is, however, no accepted gold standard method or dataset for this classification. Here, we compare classification results using gene expression data for 68 formalin-fixed paraffin-embedded DLBCL samples measured on four different gene expression platforms (Illumina wG-DASLTM arrays, Affymetrix PrimeView arrays, Illumina TrueSeq RNA sequencing and the HTG EdgeSeq DLBCL Cell of Origin Assay EU using an established platform agnostic classification algorithm (DAC) and the classifier native to the HTG platform, which is CE marked for in vitro diagnostic use (CE-IVD). Classification methods and platforms show a high level of concordance, with agreement in at least 80% of cases and rising to much higher levels for classifications of high confidence. Our results demonstrate that cell-of-origin classification by gene expression profiling on different platforms is robust, and that the use of the confidence value alongside the classification result is important in clinical applications.

Financial Effect of Unbundling Moderate Sedation from Procedural Codes in Radiology.

PURPOSE: To assess and quantify the financial effect of unbundling newly unbundled moderate sedation codes across major payors at an academic radiology practice. MATERIALS AND METHODS: Billing and reimbursement data for 23 months of unbundled moderate sedation codes were analyzed for reimbursement rates and trends. This included 10,481 and 28,189 units billed and $443,257 and $226,444 total receipts for codes 99152 (initial 15 minutes of moderate sedation) and 99153 (each subsequent 15 minute increment of moderate sedation), respectively. Five index procedures-(i) central venous port placement, (ii) endovascular tumor embolization, (iii) tunneled central venous catheter placement, (iv) percutaneous gastrostomy placement, and (v) percutaneous nephrostomy placement-were identified, and moderate sedation reimbursements for Medicare and the dominant private payor were calculated and compared to pre-bundled reimbursements. Revenue variation models across different patient insurance mixes were then created using averages from 4 common practice settings among radiologists (independent practices, all hospitals, safety-net hospitals, and non-safety-net hospitals). RESULTS: Departmental reimbursement for unbundled moderate sedation in FY2018 and FY2019 totaled $669,701.34, with high per-unit variability across payors, especially for code 99153. Across the 5 index procedures, moderate sedation reimbursement decreased 1.3% after unbundling and accounted for 3.9% of procedural revenue from Medicare and increased 11.9% and accounted for 5.5% of procedural revenue from the dominant private payor. Between different patient insurance mix models, estimated reimbursement from moderate sedation varied by as much as 29.9%. CONCLUSIONS: Departmental reimbursement from billing the new unbundled moderate sedation codes was sizable and heterogeneous, highlighting the need for consistent and accurate reporting of moderate sedation. Total collections vary by case mix, patient insurance mix, and negotiated reimbursement rates.

Daily energy expenditure in white storks is lower after fledging than in the nest.

Many juvenile birds turn into long-distance migrants within weeks of fledging. This transition involves upheavals in their energy management as major changes in growth and activity occur. Understanding such ontogenetic transitions in energy allocation has been difficult because collecting continuous data on energy costs in wild developing birds was previously largely impossible. Here, we continuously measured heart rate and fine-scale movements of 20 free-living juvenile white storks (Ciconia ciconia) using on-board bio-loggers to explore individual and environmental factors relating to daily mean heart rate. In addition, we explored which specific energy management strategy storks use during these crucial early life stages. We found that daily mean heart rate increased with overall movement activity, and increasing body temperature, but that it decreased with age. Further, we found that during the nestling period, when growth costs are high, activity costs are low, and post-fledging that activity costs are increased while maintenance costs are low, indicating a constraint on overall energy use in both phases. Our observations are consistent with the hypothesis that individuals invested more energy per unit time while still in the nest than after fledging despite the high costs of flight.

The future in their hands: Graduating student midwives' plans, job satisfaction and the desire to work in midwifery continuity of care.

BACKGROUND: Midwife-led continuity of care models benefit women and the midwives who work in them. Australian graduate midwives are familiar with, and educated to provide, continuity of care to women although the opportunity to work exclusively in positions providing continuity of care on graduation is uncommon. AIM: To explore the immediate and aspirational employment plans and workforce choices, reasons for staying in midwifery and perceptions around factors likely to influence job satisfaction of midwives about to graduate from one Australian university during the years 2012-2016. METHODS: This longitudinal study draws on survey responses from five cohorts of midwifery students in their final year of study. FINDINGS: Ninety five out of 137 midwifery students responded to the survey. Almost nine out of ten respondents either aspired to work in a continuity of care model or recognised that they would gain job satisfaction by providing continuity of care to women. Factors leading to job satisfaction identified included making a difference to the women for whom they care, working in models of care which enabled them to provide women with 'the care I want to give', and having the ability to make autonomous midwifery decisions. CONCLUSION: Aligning early graduate work experiences with continuity of care models may have a positive impact on the confidence and professional development of graduate midwives, which in turn may lead to greater satisfaction and retention among a workforce already committed to supporting the maternity healthcare reform agenda.

Exploratory Study of MYD88 L265P, Rare NLRP3 Variants, and Clonal Hematopoiesis Prevalence in Patients With Schnitzler Syndrome.

OBJECTIVE: To assess the prevalence of the MYD88 L265P mutation and variants within NLRP3 and evaluate the status of oligoclonal hematopoiesis in 30 patients with Schnitzler syndrome (SchS). METHODS: Thirty patients with SchS were recruited from 3 clinical centers. Six patients with known acquired cryopyrin-associated periodic syndromes (aCAPS) were included as controls. Allele-specific oligonucleotide-polymerase chain reaction was used for the detection of the MYD88 L265P variant, next-generation sequencing was applied to analyze NLRP3 and 28 genes associated with myelodysplastic syndrome, and gene scanning was performed for the detection of X chromosome inactivation. RESULTS: Activating NLRP3 mutations were not present in 11 SchS patients who had not been sequenced for this gene previously. The MYD88 L265P variant was present in 9 of 30 SchS patients, and somatic mutations associated with clonal hematopoiesis were identified in 1 of 30 patients with SchS and 1 of 6 patients with aCAPS. Evidence of nonrandom X chromosome inactivation was detected in 1 female patient with SchS and 1 female patient with aCAPS. CONCLUSION: A shared molecular mechanism accounting for the pathogenesis of inflammation in SchS remains elusive. Clonal hematopoiesis is not associated with other somatic mutations found in individuals with SchS or aCAPS.

Effects of a topical botanically-enriched salve on cutaneous oxygenation.

OBJECTIVE: There is a medical need to evaluate new treatments that may improve wound healing. This study aimed to determine if Original Healing Salve (OHS, Puremedy, Inc.) a topical, botanically-enriched salve (BES), changes distal leg tissue oxygenation in people with type 2 diabetes. METHOD: A randomised, controlled, crossover, double-blinded clinical trial comparing changes in cutaneous oxygen delivery (mean TcPO2) on multiple sites of the lower extremity following application of a botanically-enriched topical salve, as compared with application of the salve's base in patients with type 2 diabetes. Subjects were recruited from the general population as a convenience sample. RESULTS: A total of 16 participants were recruited. Analysis of the primary outcome demonstrated no statistically significant difference in TcPO2 at 30 minutes postapplication when comparing the BES to the base salve (BS) on the leg (-0.39±8.54mmHg; p=0.86). Analyses of secondary outcomes at 30 minutes postapplication indicated that mean TcPO2 was significantly higher than preapplication levels among subjects receiving both the BES (3.70±6.62mmHg; p=0.04) and BS on the leg (4.08±5.21mmHg; p=0.007). On the foot, mean TcPO2 at 30 minutes postapplication was higher in the BES compared with the BS, this difference was not significant (0.98±8.59mmHg; p=0.66). Mean TcPO2 was higher than preapplication levels among subjects receiving both the BES (1.21±7.70mmHg; p=0.54) and BS on the foot (2.19±7.27mmHg; p=0.25). These differences were non-significant. CONCLUSION: These findings support consideration of topical treatments containing botanical ingredients to increase cutaneous oxygen delivery in the lower extremity in patients with type 2 diabetes.

The use of targeted sequencing and flow cytometry to identify patients with a clinically significant monocytosis.

The diagnosis of chronic myelomonocytic leukemia (CMML) remains centered on morphology, meaning that the distinction from a reactive monocytosis is challenging. Mutational analysis and immunophenotyping have been proposed as potential tools for diagnosis; however, they have not been formally assessed in combination. We aimed to investigate the clinical utility of these technologies by performing targeted sequencing, in parallel with current gold standard techniques, on consecutive samples referred for investigation of monocytosis over a 2-year period (N = 283). Results were correlated with the morphological diagnosis and objective outcome measures, including overall survival (OS) and longitudinal blood counts. Somatic mutations were detected in 79% of patients, being invariably identified in those with a confirmed diagnosis (99%) but also in 57% of patients with nondiagnostic bone marrow features. The OS in nondiagnostic mutated patients was indistinguishable from those with CMML (P = .118) and significantly worse than in unmutated patients (P = .0002). On multivariate analysis, age, ASXL1, CBL, DNMT3A, NRAS, and RUNX1 mutations retained significance. Furthermore, the presence of a mutation was associated with a progressive decrease in hemoglobin/platelet levels and increasing monocyte counts compared with mutation-negative patients. Of note, the immunophenotypic features of nondiagnostic mutated patients were comparable to CMML patients, and the presence of aberrant CD56 was highly specific for detecting a mutation. Overall, somatic mutations are detected at high frequency in patients referred with a monocytosis, irrespective of diagnosis. In those without a World Health Organization-defined diagnosis, the mutation spectrum, immunophenotypic features, and OS are indistinguishable from CMML patients, and these patients should be managed as such.
