Prematurity and congenital malformations differ according to the type of pregestational diabetes. BMC Pregnancy Childbirth 2024; 24:335. [PMID: 38698309 PMCID: PMC11064320 DOI: 10.1186/s12884-024-06470-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 03/30/2024] [Indexed: 05/05/2024] Open
Abstract
BACKGROUND Diabetes mellitus (DM) is the most common metabolic disorder in pregnancy. Women with Type 2 DM seems to have no better perinatal outcomes than those with Type 1 DM. METHODS Single-center prospective cohort observational study. Pregnant women with diabetes (141 with Type 1 DM and 124 with Type 2 DM) that were followed in the university hospital between 2009 and 2021 were included in this study. Clinical data and obstetric and perinatal outcomes were collected. RESULTS As expected, women with Type 1 DM were younger and had a longer duration of diabetes than women with Type 2 DM. Obesity and chronic hypertension were higher in the group of women with Type 2 DM and their value of HbA1c in the second and third trimesters were lower than in Type 1 DM. No differences in prematurity were found, but more extreme prematurity was observed in Type 2 DM, as well as a higher rate of congenital malformations. The frequency of hypoglycemia and the weight of the newborn was higher in Type 1 DM. The maternal independent factors related to the weight of the newborn were: the glycemic control at the third trimester, the weight gain during pregnancy, and pregestational BMI. CONCLUSIONS Newborns born to mothers with Type 1 DM were larger and had a higher frequency of hypoglycemia, while congenital malformations and precocious preterm was more associated to Type 2 DM. Metabolic control, weight gain and pregestational weight were important determinants of both obstetric and neonatal complications.

Abstract
Bacterial arthritis and osteomyelitis are usually acute diseases, which in this way differ from the often insidious course of nonbacterial osteomyelitis; however, there is often an overlap both in less acute courses of bacterial illnesses and also in nonbacterial osteitis. The overlapping clinical phenomena can be explained by similar pathophysiological processes. In bacteria-related illnesses the identification of the pathogen and empirical or targeted anti-infectious treatment are prioritized, whereas no triggering agent is known for nonbacterial diseases. The diagnostics are based on the exclusion of differential diagnoses, clinical scores and magnetic resonance imaging (MRI). An activity-adapted anti-inflammatory treatment is indicated.

Abstract
Patients with type 1 diabetes mellitus (T1D) require insulin administration at all times to maintain euglycemia and metabolic stability. Insulin administration in the perioperative period is complicated by fasting requirements and perioperative stressors that can change the patient's insulin needs. In addition, many anesthesia providers are not familiar with insulin dosing strategies and technology, such as insulin pumps and continuous glucose monitors (CGMs), that are commonly used by patients with T1D. Errors in perioperative insulin administration can lead to hypoglycemia, hyperglycemia, and diabetic ketoacidosis. This article reviews common errors of associated with the perioperative management of patients with T1D, including failure to assess and coordinate patient care preoperatively; failure to understand diabetes management and technology; failure to monitor blood glucose and recognize dysglycemia; and failure to appropriately administer basal insulin.

Implementing systematic melanoma risk assessment and risk-tailored surveillance in a skin cancer focussed dermatology clinic: A qualitative study of feasibility and acceptability to patients and clinic staff. Cancer Med 2024; 13:e6976.

Abstract
BACKGROUND International bodies recommend that melanoma risk assessment should be integrated into skin cancer care provision, but evidence to support implementation is lacking. AIM To explore the acceptability and feasibility of implementing personalised melanoma risk assessment and tailored patient education and skin surveillance within routine clinical care. METHODS This prospective qualitative implementation study was informed by the Theoretical Framework of Acceptability (TFA). Personalised, systematic melanoma risk assessment was implemented in the dermatology clinic at the Melanoma Institute Australia, Sydney, Australia February-May 2021. Pre- and post-implementation observations and semi-structured interviews with patients and staff were conducted (September 2020-March 2021). Observational notes and interview transcript data were analysed thematically using the TFA as a classifying framework. RESULTS A total of 37 h of observations were made, and 29 patients and 12 clinic staff were interviewed. We found that the delivery of personalised melanoma risk estimates did not impact on patient flow through the clinic. Dermatologists reported that the personalised risk information enhanced their confidence in assessing patient risk and recommending tailored surveillance schedules. Most patients reported that the risk assessment and tailored information were a beneficial addition to their care. Among patients whose risk deviated from their expectations, some reported feeling worried, confused or mistrust in the risk information, including those at lower risk who were recommended to decrease surveillance frequency. CONCLUSIONS It is feasible and acceptable to patients and clinic staff to calculate and deliver personalised melanoma risk information and tailored surveillance as part of routine clinical care within dermatology clinics.

Abstract
INTRODUCTION Physical examination appears to be a limiting factor of teleconsultation (TC). We evaluated the feasibility of self-percussion of the lumbar fossae (sPLF) and TC for simple renal colic (SRC) in comparison with a face-to-face consultation (FC). MATERIAL AND METHODS We performed a comparative prospective study in two steps. First: evaluation of the quality of an sPLF on a standardized patient in TC, without and with tutorial. Secondarily: evaluation of a TC and a FC for a SRC with a standardized patient in real conditions. Evaluation using objective clinical scores and qualitative scales by an observer, the standardized patient and the practitioner himself. RESULTS Forty-two practitioners were included in the study. In the absence of a tutorial, the sPLF was most often "poorly done". The tutorial led to a significant improvement in the quality of sPLF. There was no difference in diagnostic and therapeutic performance among senior physicians between TC and FC. The therapeutic performances of the interns were significantly lower in TC without his being aware of it. The qualitative scores were significantly lower in TC vs FC according to the practitioners, the standardized patient and the observer. CONCLUSION An sPLF is feasible but its practice should be taught. Unlike interns, senior physicians were able to perform a TC comparable to FC for the management of SRC. TC and telesemiology therefore require dedicated training and an experienced practitioner. LEVEL OF EVIDENCE: 2

Abstract
AIMS Topical rapamycin is used to reduce facial angiofibromas in patients with tuberous sclerosis (TSC). In the absence of a commercially available preparation, numerous formulations have been tested clinically, although only in the short term. METHODS The pharmacy at Angers University Hospital (France) produced a cream formulation that was administered to people presenting this genetic disease. We conducted a questionnaire-based survey among 79 patients with TSC about their perceptions regarding the short-, medium- and long-term efficacy and safety of a topical rapamycin preparation in relation to facial angiofibromas. RESULTS This formulation was very well tolerated and its efficacy was sustained over the long term with a mean treatment duration of 33 months (extremes 1-60). Efficacy was rated ≥ 8/10 by 67.1% of patients while safety was rated ≥ 8/10 by 84.8% of patients. CONCLUSION This survey supports the safety and efficacy of topical rapamycin in the short-, medium- and long-term in the treatment of facial angiofibromas in a cohort of 79 patients with TSC.

Abstract
Einstein's general theory of relativity from 19151 remains the most successful description of gravitation. From the 1919 solar eclipse2 to the observation of gravitational waves3, the theory has passed many crucial experimental tests. However, the evolving concepts of dark matter and dark energy illustrate that there is much to be learned about the gravitating content of the universe. Singularities in the general theory of relativity and the lack of a quantum theory of gravity suggest that our picture is incomplete. It is thus prudent to explore gravity in exotic physical systems. Antimatter was unknown to Einstein in 1915. Dirac's theory4 appeared in 1928; the positron was observed5 in 1932. There has since been much speculation about gravity and antimatter. The theoretical consensus is that any laboratory mass must be attracted6 by the Earth, although some authors have considered the cosmological consequences if antimatter should be repelled by matter7-10. In the general theory of relativity, the weak equivalence principle (WEP) requires that all masses react identically to gravity, independent of their internal structure. Here we show that antihydrogen atoms, released from magnetic confinement in the ALPHA-g apparatus, behave in a way consistent with gravitational attraction to the Earth. Repulsive 'antigravity' is ruled out in this case. This experiment paves the way for precision studies of the magnitude of the gravitational acceleration between anti-atoms and the Earth to test the WEP.

Factors associated with early relapse of infantile haemangioma in children treated for at least six months with oral propranolol: A case-control study using the 2014-2021 French Ouest DataHub. Ann Dermatol Venereol 2023; 150:189-194. [PMID: 37225615 DOI: 10.1016/j.annder.2023.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 12/08/2022] [Accepted: 03/24/2023] [Indexed: 05/26/2023]
Abstract
BACKGROUND The factors associated with early relapse of infantile haemangioma (IH) after a first course of treatment with oral propranolol for at least six months (initiated after the marketing authorization had been granted) have not previously been investigated. OBJECTIVES To identify factors associated with the risk of early relapse in children with IH treated with oral propranolol according to the current prescribing guidelines. METHODS We performed a multicentre, retrospective, case-control study, using the Ouest Data Hub database. All children treated for at least 6 months with oral propranolol for IH between 31 June 2014 and 31 December 2021, and with a follow-up visit at least three months after treatment discontinuation were included. A case was defined as relapse of IH within three months of treatment discontinuation; each case was matched for age at treatment initiation and for centre, with four (relapse-free) controls. The association between relapse and treatment or IH characteristics was expressed as an odds ratio (OR) from univariate and multivariate conditional logistic regressions. RESULTS A total of 225 children were included. Of these, 36 (16%) relapsed early. In a multivariate analysis, a deep IH component was a risk factor for early relapse [OR = 8.93; 95%CI: 1.0-78.9, p = 0.05]. A propranolol dosage level of less than 3 mg/kg/day protected against early relapse [OR = 0.11; 95%CI: 0.02-0.7, p = 0.02]. Tapering before propranolol discontinuation was not associated with a lower risk of early relapse. CONCLUSION The risk factors for late and early relapse are probably different. Investigation of the risk factors for early vs. late IH relapse is now warranted.

Abstract
BACKGROUND Fungal infections, other than candidiasis and aspergillosis, are an uncommon entity. Despite this, emerging pathogens are a growing threat. In the following case report, we present the case of an immunocompromised patient suffering from two serious opportunistic infections in the same episode: the first of these, Nocardia multilobar pneumonia; and the second, skin infection by Scedosporium apiospermum. These required prolonged antibacterial and antifungal treatment. CASE PRESENTATION This case is a 71-year-old oncological patient admitted for recurrent pneumonias that was diagnosed for Nocardia pulmonary infection. Nervous system involvement was discarded and cotrimoxazole was started. Haemorrhagic skin ulcers in the lower limbs appeared after two weeks of hospital admission. We collected samples which were positive for Scedosporium apiospermum and we added voriconazole to the treatment. As a local complication, the patient presented a deep bruise that needed debridement. We completed 4 weeks of intravenous treatment with slow improvement and continued with oral treatment until the disappearance of the lesions occurs. CONCLUSIONS Opportunistic infections are a rising entity as the number of immunocompromised patients is growing due to more use of immunosuppressive therapies and transplants. Clinicians must have a high suspicion to diagnose and treat them. A fluid collaboration with Microbiology is necessary as antimicrobial resistance is frequent.

Abstract
Biological sex and gender-based constructs contribute significantly to the diversity of disease outcomes and treatment responses across the life course. To promote research considering sex and gender, the National Institutes of Health (NIH) Office of Research on Women's Health (ORWH) launched the Specialized Centers of Research Excellence (SCORE) on sex differences program. The Career Enhancement Core (CEC) of the Johns Hopkins SCORE on Sex and Age Differences in Immunity to Influenza (SADII) partnered with the Foundation for Gender-Specific Medicine, which matched NIH funding to support seed grants. Over 3 years we awarded 12 (10 were women faculty) seed grants to early-stage investigators. One year after the award, the seed grant awardees highlighted their progress, including publications, grant applications, and abstracts. All awardees noted challenges with their progress related to the COVID-19 pandemic and supply chain delays and shared suggestions for improving the programming of the CEC. They also highlighted the multiple ways the awards had helped them gain pilot data toward larger grants, build collaborative relationships, and present at the annual SCORE symposium. We describe a model and evidence supporting a private-academic collaboration to support the careers of early-stage investigators conducting research related to sex and gender.

Abstract
Introduction:
It is unclear whether the timing of meals relative to sleep impacts cardiometabolic risk factors (e.g., weight gain). This cohort study aimed to detect and describe the association of the timing of caloric intake and dietary patterns (e.g., skipping breakfast) with weight trajectory over 2 years among participants who used the Daily24 mobile application to record their timing of eating and sleeping.
Hypothesis:
We hypothesized that skipping breakfast or consuming 50% or more of daily calories in the latter half of the day is associated with greater weight gain over 2 years.
Methods:
We conducted a secondary data analysis from a multi-site, electronic health record-based cohort study of adults from 3 healthcare systems in PCORnet’s PaTH Clinical Research Network. Of the 1017 participants enrolled in the study, N=407 patients downloaded and used the Daily24 mobile application for at least 2 weekdays and 1 weekend day over 6 months. We calculated the median of each participant’s daily eating and sleeping intervals. Participants’ weights were extracted from electronic health records available for up to 10 years prior to until 10 months after baseline. Weight trajectories were calculated over 2 years of this data. Participants completed online surveys about demographics and behavioral characteristics at baseline and after 4 months. We constructed multivariate linear regression models with weight trajectory as the dependent variable and breakfast skipping (i.e., not eating anything within 3 hours of waking), having a medium or large meal within 3 hours of sleep, ≥50% caloric consumption in the latter half of the day (after 12 pm), and ≥90% caloric consumption after 7 pm as independent variables. Additional independent variables included age, sex, race, days of application use, and body mass index (BMI) category.
Results:
Mean (SD) baseline age was 50.8 (15.0) years, 75.7% had a BMI≥25 kg/m
2
, 78.1% were women, and 84.0% were white. The average number of recorded Daily24 application days was 55.9 (53.5), significantly greater than the 3-day minimum inclusion criterion. The mean of participants’ median intervals from first to last meal was 11.2 (2.0) hours. Although not statistically significant, consuming 50% of daily calories in the latter half of the day and skipping breakfast were associated with an increasing weight trajectory (0.03 and 0.25 kg/year; 95% CI -0.39 to 0.45 and -0.32 to 0.82, respectively).
Conclusions:
Timing of eating (e.g., skipping breakfast or eating most calories later in the day) may be associated with very small weight increases over time. Our app-based approach may not have had enough observations to establish this association. Further research is needed to understand the clinical importance of circadian dietary patterns related to cardiometabolic health.

Abstract
Background We aim to evaluate the association between meal intervals and weight trajectory among adults from a clinical cohort. Methods and Results This is a multisite prospective cohort study of adults recruited from 3 health systems. Over the 6-month study period, 547 participants downloaded and used a mobile application to record the timing of meals and sleep for at least 1 day. We obtained information on weight and comorbidities at each outpatient visit from electronic health records for up to 10 years before until 10 months after baseline. We used mixed linear regression to model weight trajectories. Mean age was 51.1 (SD 15.0) years, and body mass index was 30.8 (SD 7.8) kg/m2; 77.9% were women, and 77.5% reported White race. Mean interval from first to last meal was 11.5 (2.3) hours and was not associated with weight change. The number of meals per day was positively associated with weight change. The average difference in annual weight change (95% CI) associated with an increase of 1 daily meal was 0.28 kg (0.02-0.53). Conclusions Number of daily meals was positively associated with weight change over 6 years. Our findings did not support the use of time-restricted eating as a strategy for long-term weight loss in a general medical population.

Abstract
Abstract
Introduction
Recurrent episodes of aspiration pneumonia (RAP) are a significant problem in frail patients leading to high re-hospitalization and mortality. Anticipatory care planning (ACP) enables improved quality of life and end of life care. We reviewed the assessment, ACP discussions and communication with Primary Care in these patients.
Methods
We used a PDSA methodology, reviewing 116 patients with RAP referred to Speech and Language Therapy (SLT) in Elderly Medicine wards over six months, including the winter. Educational interventions were implemented. An illustrative case and pre-intervention results were presented at an online hospital-wide seminar and subsequently at an online departmental medical staff teaching session. Post-intervention analysis of 10 patients with RAP admitted over two summer months was conducted. The second round of interventions included departmental induction teaching for newly rotated doctors and creating an electronic ACP document (RAP ACP) for inclusion within the medical record.
Results
Baseline data was collected from 116 patients (mean age 85, 47% female). After the educational interventions, data was collected from 10 patients (mean age 88, 70% female). Data is being collected from winter months after the second intervention. This will be available before the conference. Baseline data demonstrated the need for improvements in documentation of Mental Capacity Assessment (MCA) specific to feeding (21.5%), ACP completion (26.7%) and flagging patients suitable for the Gold Standards Framework (GSF) on discharge (15%). Following educational interventions, there was a substantial improvement in MCA documentation (80%). Furthermore, there was a marked improvement in the completion of ACP discussions (70%). Communication of patients eligible for GSF was similar (14.2%) post-intervention.
Conclusions
Educational interventions substantially improved the quality of individualised care provided to patients with RAP. Mortality was high in both groups, yet documentation of eligibility for GSF was low, prompting further interventions targeting discharge communication.

Abstract
BACKGROUND To evaluate potential synergistic effect of pembrolizumab with radiotherapy (RT) compared with a standard-of-care (SOC) cetuximab-RT in patients with locally advanced-squamous cell carcinoma of head and neck (LA-SCCHN). PATIENTS AND METHODS Patients with nonoperated stage III-IV SCC of oral cavity, oropharynx, hypopharynx, and larynx and unfit for receiving high-dose cisplatin were enrolled. Patients received once-daily RT up to 69.96 Gy in 33 fractions with weekly cetuximab (cetuximab-RT arm) or 200 mg Q3W pembrolizumab during RT (pembrolizumab-RT arm). The primary endpoint was locoregional control (LRC) rate 15 months after RT. To detect a difference between arms of 60%-80% in 15-month LRC, inclusion of 66 patients per arm was required to achieve a power of at least 0.85 at two-sided significance level of 0.20. RESULTS Between May 2016 and October 2017, 133 patients were randomized to cetuximab-RT (n = 66) and pembrolizumab-RT (n = 67). Two patients (one in each arm) were not included in the analysis (a consent withdrawal and a progression before treatment start). The median age was 65 years (interquartile range 60-70 years), 92% were smokers, 60% were oropharynx (46% of oropharynx with p16+) and 75% were stage IV. Median follow-up was 25 months in both arms. The 15-month LRC rate was 59% with cetuximab-RT and 60% with pembrolizumab-RT ]odds ratio 1.05, 95% confidence interval (CI) 0.43-2.59; P = 0.91]. There was no significant difference between arms for progression-free survival (hazard ratio 0.85, 95% CI 0.55-1.32; P = 0.47) and for overall survival (hazard ratio 0.83, 95% CI 0.49-1.40; P = 0.49). Toxicity was lower in the pembrolizumab-RT arm than in the cetuximab-RT arm: 74% versus 92% patients with at least one grade ≥3 adverse events (P = 0.006), mainly due to mucositis, radiodermatitis, and rash. CONCLUSION Compared with the SOC cetuximab-RT, pembrolizumab concomitant with RT did not improve the tumor control and survival but appeared less toxic in unfit patients with LA-SCCHN.

Etiological diagnosis of macroglossia: Systematic review and diagnostic algorithm. Ann Dermatol Venereol 2022; 149:228-237. [PMID: 36229262 DOI: 10.1016/j.annder.2022.03.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 11/10/2021] [Accepted: 03/14/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND The objective of this literature review was to list the different etiologies of macroglossia reported in the literature, to identify characteristics that might guide diagnosis, and to create a diagnostic algorithm. METHODS The bibliographic search was carried out between October 2019 and July 2020 in the PubMed research base using the keywords "macroglossia" (MESH) and/or "tongue enlargement". RESULTS Of the 1711 references identified, 615 articles were excluded, and 1096 abstracts were reviewed. We classified the different etiologies identified according to their mechanism and whether they were congenital or acquired. The etiologies are divided into the following categories: genetic malformation syndromes, non-syndromic congenital malformations, endocrinopathies, neuromuscular diseases, storage disorders, infectious, inflammatory, traumatic, and iatrogenic diseases. CONCLUSION Based on this review, we propose a diagnostic algorithm for macroglossia according to the characteristics described. The most common diagnoses among acquired causes were amyloidosis (13.7%), endocrinopathies (8.8%), myopathies (4%) and tongue tumors (6.7%). The most common congenital causes were aneuploidy, lymphatic malformations, and Beckwith-Wiedemann syndrome, which is the main cause of congenital macroglossia, even if it appears isolated.

Abstract
Abstract
Background/Introduction
Elevated lipoprotein(a) [Lp(a)] is an inherited, independent, and causal risk factor for atherosclerotic cardiovascular disease (ASCVD). In a previous analysis of 30,510 ASCVD patients from UK Biobank, adjusted models showed a 100 nmol/L (≈50 mg/dL) difference in Lp(a) was associated with a 19% (95% CI 14–23%) higher risk of coronary revascularization (Welsh P, 2022).
Purpose
To determine the absolute risk for coronary revascularization in an ASCVD population with elevated versus normal Lp(a) levels.
Methods
This was an observational, retrospective study including 32,537 patients from UK Biobank with an ASCVD diagnosis (CHD, cerebrovascular or peripheral arterial disease). Absolute risk (AR) of coronary revascularization (number of coronary revascularizations per 100-person-years) was reported in patients with normal (<65 nmol/L ≈ 30 mg/dL; n=22,257) and elevated (≥150 nmol/L ≈ 70 mg/dL; n=5,204) Lp(a) levels across two time periods: within the first year of ASCVD diagnosis, and using all available follow-up data (median 4.7 years). Lp(a) was measured in an accredited single laboratory using a method standardized to WHO/IFCC reference material. The AR was also calculated for various subgroups within the ASCVD population.
Results
Within the first year after ASCVD diagnosis, 628 (12.07%) of the population with elevated Lp(a) underwent coronary revascularization compared to 1,787 (8.03%) with normal Lp(a). Those with elevated Lp(a) had a higher AR (14.00 per 100-person-years, 95% CI 13.02–14.99; p<0.001) than those with normal Lp(a) (9.34; 95% CI 8.92–9.76). This also held in a subgroup with myocardial infarction (MI; n=9,588), AR of 18.98 (95% CI 16.95–21.01) in those with elevated Lp(a) (n=1,571) vs. AR of 13.02 (95% CI 12.16–13.89) in those with normal Lp(a) (n=6,441) (p<0.001). AR of coronary revascularization within the first year of ASCVD diagnosis was also greater in participants with family history of CV disease (p<0.001) and premature CV disease (<60 years of age) (p<0.001). When using all available follow-up, AR of coronary revascularization was higher in participants with elevated versus normal Lp(a) in the ASCVD population (3.79 vs 2.55; p<0.001) and across all subgroups.
Conclusion
Elevated Lp(a) in patients with ASCVD was associated with increased risk of coronary revascularization in the first year (and subsequently), including those with a prior MI, premature CV disease, or family history of CV disease. Lp(a) testing in ASCVD patients can therefore aid estimations for the risk of revascularization, and thus the targeting of additional therapies to lower such risks.

GLP-2 as an indicator and modulator of acute inflammation improves cardiac function and survival in sepsis. Eur Heart J 2022.

Abstract
Abstract
Purpose
GLP-1 and GLP-2 (glucagon-like peptide-1/2) are gut hormones secreted in response to food. While GLP-1 controls glucose metabolism, GLP-2 is a local gut growth factor regulating intestinal nutrient absorption. GLP-2 has been found to be upregulated in patients with colitis. We hypothesize that beyond its local intestinal function GLP-2 might be involved in systemic immune responses.
Methods and results
To analyze whether GLP-2 secretion is modulated by the immune system, we measured circulating GLP-2 levels in 2 clinical cohorts. In the first cohort (n=34) GLP-2 levels increased over time following cardiac surgery as an inflammatory stimulus. In the second cohort 223 patients with sepsis had a 3.9 fold increase of GLP-2 plasma levels vs. 53 healthy controls (3.0 ng/mL vs. 11.4 ng/mL; p<0.001). High GLP-2 levels were associated with markers of inflammation (IL-6, PCT, CRP), septic cardiomyopathy (NT-proBNP) and independently predicted mortality in humans with sepsis. Induction of sepsis in mice by endotoxin or cecal ligation puncture strongly increased GLP-2 levels independent from food intake. By injecting various proinflammatory cytokines and inducing sepsis in IL1R−/− and IL6−/− mice we identified that inflammation upregulates GLP-2 secretion through IL-6. To identify the source of GLP-2 secretion under inflammation, we induced sepsis in Gcg−/− mice lacking endogenous GLP-2 production with a tissue-specific reactivation of Gcg in gut L-cells (GcgRAΔvilCre) or pancretic alpha cells (GcgRAΔPDX1-Cre). We observed sepsis-induced GLP-2 secretion to be derived from the pancreas and not from the gut. Additional in-vitro and ex-vivo approaches revealed that IL-6 directly activates GLP-2 secretion from pancreatic alpha cells. Gcg−/− mice lacking GLP-2 production and Glp2r−/− mice show aggravated sepsis indicating that endogenous upregulation of GLP-2 is protective. Finally, we analyzed whether inflammatory upregulation of GLP-2 has immunomodulatory relevance. We administered GLP-2 or saline as control per central jugular vein catheter mice who underwent CLP. GLP-2 treatment improved LV-contractility (dp/dtmax) in septic cardiomyopathy (control 7361 vs. GLP-2 9500 mmHg/s; p<0.01), inhibited sepsis-induced hypotension and reduced mortality (p=0.018). Mechanistically GLP-2 reduced myeloid immune cell infiltration into heart and liver tissue and decreased proinflammatory cytokine levels in various organs and the blood (TNF-α, IL-6 and IL-1β). After broad GLP-2 receptor profiling we found maximum mRNA expression in gut tissues with no expression on immune cells. By further mechanistic studies we found GLP-2 to protect against sepsis-induced gut barrier dysfunction.
Conclusions
Here we identified a counter-regulatory control system in which IL-6 derived upregulation of GLP-2 secretion limits excessive innate immune responses and protects against sepsis. These findings might open new avenues for the treatment of patients with inflammatory diseases.

Abstract
During recovery phases following a nuclear or radiological incident analyses of doses received by members of the public and responders are often required. Several methods have been investigated for use at different timescales after the incident, including assessments based on measurements of materials present at the time of the incident. Common salt has previously been shown to have potential for retrospective dosimetry in the mGy dose range using laboratory instrumentation. This preliminary study investigates the use of portable instruments, with unprepared commercially sourced salt, in dose ranges below 100 μGy. Responses from pulsed IRSL and portable OSL instruments were compared. For OSL measurements, detection limits of 7 μGy have been demonstrated, with detection limits of 30-340 μGy for the other instruments investigated. Dose responses in the 0-500 μGy range were determined for the most sensitive systems, which show a linear response over this dose range with a non-zero intercept representing doses received from environmental sources since manufacture of the salt. For use as a dosimeter, methods of removing or accounting for inherited signals will be required in this low dose range. The results demonstrate that salt has considerable potential for use in retrospective dosimetry below 100 μGy, and that measurements can be conducted with portable OSL instruments.

Abstract
BackgroundSystemic autoimmune rheumatic disease (SARD) patients may be at risk for disease flare and prolonged symptom duration after COVID-19, perhaps related to DMARD disruption and immune activation.ObjectivesTo describe DMARD disruption and identify differences in SARD activity among patients with and without prolonged COVID-19 symptom duration.MethodsWe identified all SARD patients with confirmed COVID-19 at the Mass General Brigham healthcare system in Boston, USA; prospective recruitment is ongoing. Surveys were used to collect demographics, clinical characteristics, DMARD disruption, COVID-19 course, and SARD disease activity before and after COVID-19. The survey included validated instruments measuring disease activity, pain, fatigue, functional status, and respiratory quality of life. Prolonged symptom duration was defined as COVID-19 symptoms lasting ≥28 days. We compared differences in patient-reported measures between those with and without prolonged symptoms.ResultsWe analyzed survey responses from 174 COVID-19 survivors with SARDs (mean age 52±16 years, 81% female, 80% White). The most common SARDs were RA (40%) and SLE (14%). Fifty-one percent of the 127 respondents on any DMARD reported a disruption to their regimen at COVID-19 onset (Figure 1). Among individual DMARDs, 56-77% were reported to have any change, except for hydroxychloroquine (23%) and rituximab (46%). SARD flare after COVID-19 was reported by 41% of respondents (Table 1). Patient global assessment of SARD activity was worse after COVID-19 (mean 7.6±2.3 before vs. 6.6±2.9 after COVID-19, p<0.001). Prolonged symptom duration was reported by 45% of participants. Those with prolonged symptoms had a higher initial COVID-19 symptom count (median 7 vs. 4, p<0.001) and were more likely to be hospitalized for COVID-19 (28% vs. 17%, p=0.001). Respondents experiencing prolonged symptom duration had higher disease activity on RAPID3 (p=0.007) as well as more pain (p<0.001) and fatigue (p=0.03) compared to those without prolonged symptoms.Table 1.Acute COVID-19 course, SARD flare/activity, and patient-reported outcomes among COVID-19 survivors with SARDs.All COVID-19 survivors with SARDs (n=174)Prolonged symptom duration ≥28 days (n=78)No prolonged symptom duration/(n=96)p-value (prolonged vs. not)Acute COVID-19 courseCOVID-19 symptom duration, days, median [IQR]14 [9, 29]46 [30, 65]11 [7, 14]<0.0001Initial symptom count, median [IQR]6 [3, 8]7 [6, 9]4 [2, 7]<0.001Hospitalized, n (%)38 (22)22 (28)16 (17)0.001SARD flare/activitySelf-reported SARD flare after COVID-19, n (%)71 (41)38 (49)33 (34)0.15Disease activity by RAPID3, median [IQR]9 [4, 14]11.2 [6, 16]7 [3, 13]0.0067RAPID3 categorical score, n (%)0.13Remission (0)11 (7)4 (5)7 (7)Near remission (0.3-1.0)23 (14)5 (7)18 (19)Low severity (1.3-2.0)26 (15)10 (14)16 (17)Moderate severity (2.3-4.0)55 (33)27 (36)28 (29)High severity (4.3-10.0)54 (32)28 (38)26 (27)Patient-reported outcomesPain by SF-MPQ, median [IQR]2 [1, 2]2 [1, 2]1 [0, 2]0.0008Fatigue by FSI, median [IQR]53 [27, 84]66 [31, 91.5]43 [26, 76]0.031mHAQ, median [IQR]0.125 [0, 0.38]0.25 [0, 0.75]0.125 [0, 0.38]0.11Respiratory quality of life by SGRQ, global [IQR]15 [4, 29]16 [4, 36]10 [4, 26]0.49RAPID3, Routine Assessment of Patient Index Data 3; SF-MPQ, Short-form McGill Pain Questionnaire; FSI, Fatigue Symptom Inventory; mHAQ, modified Health Assessment Questionnaire; SGRQ, Saint George’s Respiratory Questionnaire.Figure 1.Frequency of baseline DMARD use and proportion with any disruption at COVID-19 onset.ConclusionDMARD disruption, SARD flare, and prolonged symptoms were common in this prospective study of COVID-19 survivors with SARDs.

Abstract
BackgroundAnti-TNF drugs have dramatically improved the management of inflammatory arthritis (IA).Although the introduction of biosimilars have reduced the cost, chronic use of biologic agentshas a high impact on healthcare expenditure. This study evaluated the cost effectiveness of adose reduction strategy for the most commonly used anti- TNF drugs over a period of 10 yearsin patients with IA in remission.ObjectivesThe purpose of this study was to explore whether patients with Inflammatory Arthritis (IA) (Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) or Ankylosing Spondylitis (AS) would remain in remission after 10 year period, following a reduction in biologic dosing frequency and to calculate the cost savings associated with dose reduction.MethodsThis prospective, non-blinded, non-randomised study was commenced in 2010. Patientswith IA, Rheumatoid arthritis (RA),ankylosing spondylitis (AS) and Psoriatic arthritis (PsA)who were in remission as defined by disease activity indices (DAS28<2.6, BASDAI<4), andwere offered Anti TNF dose reduction. Patients on etanercept were reduced from 50mgweekly to fortnightly, adalimumab 40mg once monthly instead of fortnightly. Patients wereassessed for disease activity at 1, 4 and 10 years following reduction in dosingfrequency.Cost saving was calculated by deducting the total annual cost of the biologicagent used over 10 years compared with the cost if the dosing interval had not changed.ResultsSeventy nine patients with inflammatory arthritis in remission were recruited. 57% had rheumatoid arthritis (n=45), 13% psoriatic arthritis (n=10) and 30% ankylosing spondylitis (n=24). 57% (n=45) were taking etanercept and 43% (n=34) adalimumab. The percentage of patients who maintained dose reduction at 10 years was 9% (n=7). Of the total 48 patients who were successfully dose reduced at year 1 (n=42), (69%, n=29) were able to maintain the dose reduction up to 4 years and 9% (n=7) maintained this dose reduction up to year 10. The estimated cost saving was €4,928 per patient per year. Estimated cost savings for 7 patients on reduced dose was €344,952.88 over 10 years.ConclusionAnti TNF dose reduction strategy in patients with IA results in substantial cost savings. Implementation of a dose reduction strategy while monitoring of disease activity reduces the financial impact of the use of biologic therapies. Further studies should be done to identify which patients are more likely to remain in remission while on dose reduction.References[1]Bonafede MM, Gandra SR, Watson C, Princic N, Fox KM.

Abstract
BackgroundGiant cell arteritis (GCA) is a large-vessel vasculitis mainly involving the aorta and cranial arteries. It is the most frequent vasculitis in adults over 50 years. When they are stimulated by interferon-gamma (IFN-γ), vascular smooth muscle cells (VSMC) contribute to GCA pathogenesis by producing chemokines triggering the recruitment of pro-inflammatory T cells and monocytes (1).ObjectivesCurrent knowledge about the interaction between resident cells of the vascular wall (VSMC, myofibroblasts [MF]) and immune cells is limited. The aim of our research was to better characterize the interactions between VSMC, MF and T cells in GCA.MethodsFresh fragments of temporal artery biopsies (TAB) performed at Dijon university hospital (France) were prospectively sent to our research unit. Fresh sections of positive and negative TAB were fixed and embedded in optimal cutting temperature OCT and stored at -80°C. Then, cryostat sections were fixed, permeabilized, blocked and incubated with primary antibodies (anti-alpha smooth muscle actin [α-SMA], anti-myosin heavy chain 11 [MHC11], anti-Desmin, anti CD90, anti-CD45, anti-HLA-DR, anti-phospho STAT1 [pSTAT1] and anti-pSTAT3) and secondary antibodies for confocal microscopy analyses. Fresh sections of healthy TAB were embedded in MATRIGEL and covered by DMEM to obtain vascular cells in culture. Cells were treated with trypsina-EDTA between each passage. Vascular cells were used after 4-7 doubling passages. Cells were analyzed by immunofluorescence, flow cytometry and RT-PCR and their proliferation was evaluated by impedancemetry (iCELLigence system). Peripheral blood mononuclear cells (PBMC) and vascular cells thus obtained were co-cultured for 7 days in different conditions. Vascular cells were cultured in the presence or absence of IFN-γ and tumor necrosis factor alpha (TNF-α) or interleukin-6 (IL-6) and soluble receptor of IL-6 for 72 hours. When cells reached confluence, they were cultured alone or with allogenic PBMC activated with anti-CD3/CD28 microbeads. After 7 days of culture, cells were separated with a treatment with EDTA and studied by flow cytometry.ResultsConfocal microscopy analyses of GCA arteries showed that neointima was mainly composed of myofibroblasts (MF) (α-SMA+Desmin+MHC11lowCD90+) in contact with CD45+ cells and that MF expressed HLA-DR, the phosphorylated form of STAT1 (pSTAT1) and in a lesser extent pSTAT3, strongly suggesting the activation of the IFN-γ signaling pathway rather than the IL-6 pathway. The phenotype of cultured vascular cells isolated from fresh TAB was consistent with MF. When MF were exposed to IFN-γ and TNF-α in vitro, their proliferation capacity decreased and their levels of expression of HLA-DR and CD86 increased (median fluorescence intensity [MFI] from 0 to 57 [p=0.03] and from 34 to 103 [p=0.03], respectively). In addition, co-cultures of MF and activated PBMC revealed that MF maintained the polarization of T cells into Th1 and Tc1 cells (p≤0.001) and to a lesser extent into Th17 and Tc17 cells (p=0.03). This effect was even more significant when MF were previously exposed to IFN-γ and TNF-α but not when they were exposed to IL-6.ConclusionOur results show that myofibroblasts are present in the neointima of GCA patients and that these MF activate signaling pathways indicative of IFN-γ exposure. Moreover, these MF, especially when exposed to IFN-γ, maintain the polarization of T cells into Th1 and Tc1 cells, which contributes to amplify the production of IFN-γ and thus initiate a pro-inflammatory amplification loop that likely participates in vascular inflammation and remodelling.References[1]Corbera-Bellalta M, Planas-Rigol E, Lozano E, Terrades-Garcia N, Alba MA, Prieto-Gonzalez S, et al.

Healthy for Two/Healthy for You: Design and methods for a pragmatic randomized clinical trial to limit gestational weight gain and prevent obesity in the prenatal care setting. Contemp Clin Trials 2022; 113:106647. [PMID: 34896296 PMCID: PMC8844210 DOI: 10.1016/j.cct.2021.106647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 11/30/2021] [Accepted: 12/03/2021] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To compare the effect of Healthy for Two/Healthy for You (H42/H4U), a health coaching program, in prenatal care clinics that serve a racially and economically diverse population, on total gestational weight gain (GWG) (vs. usual care). We hypothesize that compared to usual prenatal care, intervention participants will have lower GWG and lower rates of gestational diabetes mellitus (GDM). METHODS We report the rationale and design of a pragmatic, parallel arm randomized clinical trial with 380 pregnant patients ≤15 weeks gestation with overweight or obesity from one of 6 academic and community-based obstetrics practices, randomized to either H42/H4U or usual prenatal care in a 1:1 ratio. The study duration is early pregnancy to 6 months postpartum. The primary outcome is total GWG, calculated as the difference between first clinic-assessed pregnancy weight and the weight at 37 weeks gestation. Key maternal and infant secondary outcomes include GDM incidence, weight retention at 6 months postpartum, infant weight, maternal health behaviors and wellness. CONCLUSIONS This pragmatic clinical trial embeds a pregnancy health coaching program into prenatal care to allow parallel testing compared to usual prenatal care on the outcome of total GWG. The real-world design provides an approach to enhance its sustainability beyond the trial to ultimately improve maternal/child health outcomes and reduce future obesity. TRIAL REGISTRATION The study was first registered at clinicaltrials.gov on 1/26/21 (NCT04724330).

Enterocyte-innate lymphoid cell crosstalk drives early IFN-γ-mediated control of Cryptosporidium. Mucosal Immunol 2022; 15:362-372.

Abstract
The intestinal parasite, Cryptosporidium, is a major contributor to global child mortality and causes opportunistic infection in immune deficient individuals. Innate resistance to Cryptosporidium, which specifically invades enterocytes, is dependent on the production of IFN-γ, yet whether enterocytes contribute to parasite control is poorly understood. In this study, utilizing a mouse-adapted strain of C. parvum, we show that epithelial-derived IL-18 synergized with IL-12 to stimulate innate lymphoid cell (ILC) production of IFN-γ required for early parasite control. The loss of IFN-γ-mediated STAT1 signaling in enterocytes, but not dendritic cells or macrophages, antagonized early parasite control. Transcriptional profiling of enterocytes from infected mice identified an IFN-γ signature and enrichment of the anti-microbial effectors IDO, GBP, and IRG. Deletion experiments identified a role for Irgm1/m3 in parasite control. Thus, enterocytes promote ILC production of IFN-γ that acts on enterocytes to restrict the growth of Cryptosporidium.

Radiative Capture on Nuclear Isomers: Direct Measurement of the ^{26m}Al(p,γ)^{27}Si Reaction. PHYSICAL REVIEW LETTERS 2022; 128:042701.

Abstract
We present the first direct measurement of an astrophysical reaction using a radioactive beam of isomeric nuclei. In particular, we have measured the strength of the key 447-keV resonance in the ^{26m}Al(p,γ)^{27}Si reaction to be 432_{-226}^{+146} meV and find that this resonance dominates the thermally averaged reaction rate for temperatures between 0.3 and 2.5 GK. This work represents a critical development in resolving one of the longest standing issues in nuclear astrophysics research, relating to the measurement of proton capture reactions on excited quantum levels, and offers unique insight into the destruction of isomeric ^{26}Al in astrophysical plasmas.

Low concentration Phloxine B staining for high chemical contrast, nonlinear microscope mosaic imaging of skin alterations in pseudoxanthoma elasticum. BIOMEDICAL OPTICS EXPRESS 2022; 13:252-261.

Abstract
Pseudoxanthoma elasticum (PXE) is an autosomal recessive metabolic disorder characterized by ectopic mineralization of soft connective tissue. Histopathology findings include fragmented, mineralized elastic fibers and calcium deposits in the mid-dermis. Nonlinear microscopy (NLM) can be used for visualization of these histopathological alterations of the mid-dermis in PXE-affected skin sections. Upon introducing a normalized 3D color vector representation of emission spectra of three of the main tissue components (collagen, elastin and calcification) we found that due to their broad, overlapping emission spectra, spectral separation of emission from elastin and calcification is practically impossible in fresh-frozen or unstained, deparaffinized PXE sections. However, we found that the application of a low concentration Phloxine B staining after the deparaffinization process creates an imaging contrast for these two tissue components, which enables spectral decomposition of their fluorescence images. The obtained concentration maps for calcium deposits can be well suited for the determination of illness severity by quantitative analysis.

Safety and efficacy of low-dose PI3K inhibitor taselisib in adult patients with CLOVES and Klippel-Trenaunay syndrome (KTS): the TOTEM trial, a phase 1/2 multicenter, open-label, single-arm study. Genet Med 2021; 23:2433-2442.

Abstract
PURPOSE PIK3CA pathogenic variants in the PIK3CA-related overgrowth spectrum (PROS) activate phosphoinositide 3-kinase signaling, providing a rationale for targeted therapy, but no drug has proven efficacy and safety in this population. Our aim was to establish the six-month tolerability and efficacy of low-dose taselisib, a selective class I PI3K inhibitor, in PROS patients. METHODS Patients over 16 years with PROS and PIK3CA pathogenic variants were included in a phase IB/IIA multicenter, open-label single-arm trial (six patients at 1 mg/day of taselisib, then 24 at 2 mg/day). The primary outcome was the occurrence of dose limiting toxicity (DLT). Efficacy outcomes were the relative changes after treatment of (1) tissue volume at affected and unaffected sites, both clinically and on imaging; (2) cutaneous vascular outcomes when relevant; (3) biologic parameters; (4) quality of life; and (5) patient-reported outcomes. RESULTS Among 19 enrolled patients, 2 experienced a DLT (enteritis and pachymeningitis) leading to early trial termination (17 treated, 10 completed the study). No serious adverse reaction occurred in the 1 mg cohort (n = 6). No significant reduction in affected tissue volume was observed (mean -4.2%; p = 0.81; SD 14.01). Thirteen (76.4%) participants reported clinical improvement (pain reduction, chronic bleeding resolution, functional improvement). CONCLUSION Despite functional improvement, the safety profile of low-dose taselisib precludes its long-term use.

Abstract
Abstract
Background
Besides targeted temperature management (TTM), no other therapeutic strategy has shown to improve neurological outcome in cardiac arrest patients. Recently, it has been suggested that higher levels of mean arterial blood pressure (>90 mmHg) may have a protective neurological effect in this population, yet data is scarce.
Objective
To describe the association between neurological outcomes and MAP during TTM.
Methods
Retrospective study of a prospective database including survivors of a cardiac arrest undergoing TTM and admitted to the acute cardiac care of a tertiary university hospital from September 2007 to July 2020. MAP was recorded from arrival and hourly during TTM. Neurological outcome was graded 3 months after initial event using the Pittsburgh Cerebral Performance Category (CPC) scale and patients were divided classified as follows: Group A patients with CPC of 1 to 2 (good neurological outcome), and group B, with CPC 3 to 5 (poor neurological outcome or death). As CPC 5 comprises patients who have died but whose cause of death may not be related to their neurological condition, we sort to control this potential source of bias, by including a variable of “severe neurological injury”, which includes patients with CPC 3–4 and those CPC 5 who died due to WLST due to poor neurological prognosis/brain death.
Results
A total pf 431 patients were analysed. Baseline and cardiac arrest characteristics are depicted in Table 1. Patients in group B had a higher proportion of non-witnessed cardiac arrest, out-of-hospital cardiac arrest, non-shockable rhythm, and longer time before ROSC. The relation between MAP and neurological outcome is shown in Table 2. The were no differences of MAP in day 1 and 3 between groups. MAP was statistically higher in Group A during day 2 or rewarming phase. Mean MAP during day 1 and 2; and during day 1, 2 and 3 was also significantly higher in group A. However, when same analysis was performed under the variable “severe neurological injury” no statistically significant differences were observed.
Conclusion
There is no association between MAP and neurological outcomes, when true “severe neurological injury” is analysed. Therefore, and until further data is obtained, following actual practical guidelines or avoiding hypotension seems to be the goal in this population, as higher MAP may also have deleterious effects.
