[PMID: 38776289 PMCID: PMC11111077 DOI: 10.1371/journal.pone.0302964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Accepted: 04/17/2024] [Indexed: 05/24/2024] Open
Abstract
BACKGROUND Iron deficiency anemia (IDA) is a prevalent hematological complication associated with gastrointestinal (GI) cancers due to an increased loss of iron and decreased iron absorption. The purpose of this systematic review is to evaluate the use of parenteral iron to treat IDA in patients with GI cancer. METHODS PubMed, Cochrane, EMBASE, CINHAL and Scopus were searched from January 1, 2010 to September 29, 2023 with no language restrictions. We excluded editorials, case reports, abstracts, conference papers, and poster presentations. Studies were included if they discussed IDA, GI neoplasms, use of iron supplementation (with or without erythropoietin-stimulating agents [ESAs]), defined anemia and had an adult patient population. We assessed the efficacy of parenteral iron in comparison to other iron supplementation methods when treating IDA in patients with GI cancer. The Cochrane Risk of Bias Tool 2 (RoB 2) and the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) assessment tools were used to assess the quality of the included studies. Moreover, the Cochrane Effective Practice and Organization data collection form was used to collect pertinent study information. RESULTS Our search yielded 3,969 studies across all databases. Twenty-one studies were included (6 randomized control trials; 15 non-randomized studies). Of the 15 studies evaluating hemoglobin (Hb) response, seven studies found an increase in Hb levels when patients were treated with IV iron. The 14 studies evaluating red blood cell (RBC) transfusion rates found conflicting differences in RBC transfusion needs when treated with IV iron. Studies analyzing health related outcomes typically found an increase in quality of life and decreased post-operative complications. DISCUSSION This review demonstrates improved outcomes of IDA in patients with GI cancer treated with IV iron instead of other iron supplementation methods. Timely diagnosis and appropriate IDA management can greatly improve quality of life in this patient population, especially if myelosuppressive chemotherapy is required.

COVID-19 Stroke Apical Lung Examination Study 2: a national prospective CTA biomarker study of the lung apices, in patients presenting with suspected acute stroke (COVID SALES 2). Neuroimage Clin 2024; 42:103590. [PMID: 38513535 DOI: 10.1016/j.nicl.2024.103590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 03/10/2024] [Accepted: 03/13/2024] [Indexed: 03/23/2024]
Abstract
BACKGROUND Apical ground-glass opacification (GGO) identified on CT angiography (CTA) performed for suspected acute stroke was developed in 2020 as a coronavirus-disease-2019 (COVID-19) diagnostic and prognostic biomarker in a retrospective study during the first wave of COVID-19. OBJECTIVE To prospectively validate whether GGO on CTA performed for suspected acute stroke is a reliable COVID-19 diagnostic and prognostic biomarker and whether it is reliable for COVID-19 vaccinated patients. METHODS In this prospective, pragmatic, national, multi-center validation study performed at 13 sites, we captured study data consecutively in patients undergoing CTA for suspected acute stroke from January-March 2021. Demographic and clinical features associated with stroke and COVID-19 were incorporated. The primary outcome was the likelihood of reverse-transcriptase-polymerase-chain-reaction swab-test-confirmed COVID-19 using the GGO biomarker. Secondary outcomes investigated were functional status at discharge and survival analyses at 30 and 90 days. Univariate and multivariable statistical analyses were employed. RESULTS CTAs from 1,111 patients were analyzed, with apical GGO identified in 8.5 % during a period of high COVID-19 prevalence. GGO showed good inter-rater reliability (Fleiss κ = 0.77); and high COVID-19 specificity (93.7 %, 91.8-95.2) and negative predictive value (NPV; 97.8 %, 96.5-98.6). In subgroup analysis of vaccinated patients, GGO remained a good diagnostic biomarker (specificity 93.1 %, 89.8-95.5; NPV 99.7 %, 98.3-100.0). Patients with COVID-19 were more likely to have higher stroke score (NIHSS (mean +/- SD) 6.9 +/- 6.9, COVID-19 negative, 9.7 +/- 9.0, COVID-19 positive; p = 0.01), carotid occlusions (6.2 % negative, 14.9 % positive; p = 0.02), and larger infarcts on presentation CT (ASPECTS 9.4 +/- 1.5, COVID-19 negative, 8.6 +/- 2.4, COVID-19 positive; p = 0.00). After multivariable logistic regression, GGO (odds ratio 15.7, 6.2-40.1), myalgia (8.9, 2.1-38.2) and higher core body temperature (1.9, 1.1-3.2) were independent COVID-19 predictors. GGO was associated with worse functional outcome on discharge and worse survival after univariate analysis. However, after adjustment for factors including stroke severity, GGO was not independently predictive of functional outcome or mortality. CONCLUSION Apical GGO on CTA performed for patients with suspected acute stroke is a reliable diagnostic biomarker for COVID-19, which in combination with clinical features may be useful in COVID-19 triage.

Abstract
The cross section of the ^{13}C(α,n)^{16}O reaction is needed for nuclear astrophysics and applications to a precision of 10% or better, yet inconsistencies among 50 years of experimental studies currently lead to an uncertainty of ≈15%. Using a state-of-the-art neutron detection array, we have performed a high resolution differential cross section study covering a broad energy range. These measurements result in a dramatic improvement in the extrapolation of the cross section to stellar energies potentially reducing the uncertainty to ≈5% and resolving long standing discrepancies in higher energy data.

Abstract
PURPOSE To optimize real-time PCR assays for diagnosis of Bacterial Vaginosis (BV) and determine cut-off loads by ROC analysis for Gardnerella vaginalis, Atopobium vaginae and Lactobacillus spp. as compared to Nugent scoring (Gold standard) in clinical samples. RESULTS Out of 125 women, 34 were positive, 26 intermediate and 65 negative for BV by Nugent scoring. All three real-time PCR assays were found to be highly sensitive & specific and AUC suggested excellent diagnostic accuracy. An optimal cut-off was >9.45 × 103 copies/ ml, >3.34 × 103 copies/ ml & ≤ 18.63 × 103 copies/ ml for G. vaginalis, A. vaginae and Lactobacillus spp. respectively, in BV positives. Gram staining and qPCR were discordant only in patients with intermediate scores (n = 26) where qPCR identified 15 (57.69%) as positive and 11 (42.3%) as negative. CONCLUSION PCR-based molecular BV diagnosis is more accurate and can be used for deciphering intermediate Nugent scores.

Abstract
PURPOSE The objective of this study was to assess the microleakage and flexural strength of glass ionomer cement (GIC) and modified GIC (Zirconomer) when coated with protective coating agents such as COAT-IT and G-COAT plus. METHODS Sixty tooth specimens were grouped into two groups based on the type of restorations (GIC (n = 30) and Zirconomer (n = 30)). The samples were further divided into three subgroups (n = 10) based on the protective coating agent (Petroleum jelly, G-COAT Plus, or COAT IT) applied. This study evaluated the microleakage at the occlusal and cervical margins of class V restoration after being subjected to dye penetration and sectioning. Each specimen was viewed under a 40 × microscope and was given scores based on the depth of dye penetration. They were statistically analyzed using the Kruskal-Wallis test and compared within the groups using the Mann- Whitney Test. In addition, flexural strength was assessed using standardized cuboid (25 × 2 × 2 mm) specimens of restorative materials with and without protective coating agents. The mean flexural strength data of all the subgroups were statistically evaluated using a one-way analysis of variance (ANOVA) and compared within the subgroups using the student t test. RESULTS A statistically significant difference was found when occlusal margin microleakage scores were evaluated with G-COAT Plus demonstrating the lowest occlusal margin microleakage when applied over GIC restoration. The increasing order of occlusal margin microleakage scores is as follows: GIC with G-COAT Plus, Zirconomer with COAT-IT, GIC with COAT-IT, GIC, Zirconomer with G-COAT Plus, and Zirconomer. However, the cervical margin microleakage scores revealed no significant difference. While flexural strength was found to be highest for the GIC group coated with G-COAT Plus, it was observed that there was a significant improvement in the flexural strength of both GIC and Zirconomer when coated with either of the protective coating agents. CONCLUSION Within the limitations of this in vitro study, it was observed that the application of protective coating agents can significantly reduce the potential microleakage and improve the flexural strength of the restorative material especially when zirconia-reinforced GIC is the restorative material.

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. [PMID: 38379327 PMCID: PMC10839129 DOI: 10.1002/cam4.6976] [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: 10/11/2023] [Revised: 01/10/2024] [Accepted: 01/18/2024] [Indexed: 02/22/2024] Open
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.

Optical Coherence Tomography Predictors of SIde Branch REstenosis after unprotected Left Main bifurcation angioplasty using double kissing crush technique (OP-SIBRE LM Study). Catheter Cardiovasc Interv 2024; 103:51-60.

Abstract
BACKGROUND Among the two stent strategies, contemporary evidence favors double kissing crush technique (DKC) for complex unprotected distal left main bifurcation (UdLMB) lesions. However one of the major challenges to these lesions is side branch (SB) restenosis. AIMS Our aim was to identify optical coherence tomographic (OCT) characteristics that may predict SB restenosis (SBR) after UdLMB angioplasty using DKC technique. METHODS This was a single-center, retrospective study that included 60 patients with complex UdLMB disease, who underwent OCT-guided angioplasty using DKC technique. Angiographic follow-up was performed in all patients at 1 year to identify patients with SBR. Patients with SBR group were compared with patients without SBR (NSBR group) for OCT parameters during index procedure. RESULTS Twelve (20%) patients developed SBR at 1-year follow-up. The SBR group had longer SB lesion (18.8 ± 3.2 vs. 15.3 ± 3.7 mm, p = 0.004) and neo-metallic carinal length (2.1 vs. 0.1 mm, p < 0.001) when compared to the NSBR group. Longer neo-metallic carinal length was associated with the absence of the dumbbell sign, presence of hanging stent struts across the SB ostium on OCT of final MB pullback. On multivariate regression analysis, SB distal reference diameter (DRD) and SB stent expansion were identified as independent predictors of SBR with SB-DRD of ≤2.8 mm (area under curve-0.73, sensitivity-83.3%, and specificity-62.5%) and SB stent expansion of ≤89% (area under curve-0.88, sensitivity-83.3%, and specificity- 81.2%) as the best cut off values to predict SBR. CONCLUSIONS SB DRD and SB stent expansion are the OCT predictors of future SBR after UdLMB angioplasty using DKC technique.

Abstract
A 49-year-old male presented with class III exertional angina, 1 year after angioplasty of the left anterior descending artery (LAD) and right coronary artery. Coronary angiogram revealed 90% in-stent restenosis (ISR) in mid-LAD with angiographic impression of stent fracture. Optical coherence tomographic evaluation of mid-LAD ISR showed a distinct 3 mm long "eclipse sign" indicating embolized, broken guiding catheter tip as a cause of ISR, which was confirmed on reviewing 1-year-old angiographic images. This was managed with "cut and fix technique" using cutting balloon and another drug-eluting stent. Optical coherence tomographic at 9 months showed well endothelialized stent with a thin layer of neo-intimal hyperplasia over the sandwiched broken guiding tip.

Abstract
In this Letter, we present the design and performance of the frequency-dependent squeezed vacuum source that will be used for the broadband quantum noise reduction of the Advanced Virgo Plus gravitational-wave detector in the upcoming observation run. The frequency-dependent squeezed field is generated by a phase rotation of a frequency-independent squeezed state through a 285 m long, high-finesse, near-detuned optical resonator. With about 8.5 dB of generated squeezing, up to 5.6 dB of quantum noise suppression has been measured at high frequency while close to the filter cavity resonance frequency, the intracavity losses limit this value to about 2 dB. Frequency-dependent squeezing is produced with a rotation frequency stability of about 6 Hz rms, which is maintained over the long term. The achieved results fulfill the frequency dependent squeezed vacuum source requirements for Advanced Virgo Plus. With the current squeezing source, considering also the estimated squeezing degradation induced by the interferometer, we expect a reduction of the quantum shot noise and radiation pressure noise of up to 4.5 dB and 2 dB, respectively.

Abstract
Cranioplasty, specifically a repair of the skull defect resulting from a previous decompressive craniectomy, is a relatively simple procedure associated with a minimal rate of complications. Even though seizures are seen in up to 30% of the patients postoperatively, status epilepticus is not commonly described. Cerebral oedema, ischaemia and neuro-inflammation have been reported as putative causes of seizures in this population. Here, we report a case of refractory status epilepticus unresponsive to standard anti-epileptic and anaesthetic agents. The use of dexmedetomidine helped terminate the episode and led to a favourable outcome. Most of the standard anti-epileptic and anaesthetic agents act through potentiation of GABAergic transmission or sodium channel blockade and postsynaptic adrenoceptor activation by dexmedetomidine may help potentiate their effect. Further studies are needed to investigate its anticonvulsant effect on post-traumatic brain injury and elaborate on optimal dosage.

Abstract
BACKGROUND AND PURPOSE Identifying the presence and extent of intracranial thrombi is crucial in selecting patients with acute ischemic stroke for treatment. This article aims to develop an automated approach to quantify thrombus on NCCT and CTA in patients with stroke. MATERIALS AND METHODS A total of 499 patients with large-vessel occlusion from the Safety and Efficacy of Nerinetide in Subjects Undergoing Endovascular Thrombectomy for Stroke (ESCAPE-NA1) trial were included. All patients had thin-section NCCT and CTA images. Thrombi contoured manually were used as reference standard. A deep learning approach was developed to segment thrombi automatically. Of 499 patients, 263 and 66 patients were randomly selected to train and validate the deep learning model, respectively; the remaining 170 patients were independently used for testing. The deep learning model was quantitatively compared with the reference standard using the Dice coefficient and volumetric error. The proposed deep learning model was externally tested on 83 patients with and without large-vessel occlusion from another independent trial. RESULTS The developed deep learning approach obtained a Dice coefficient of 70.7% (interquartile range, 58.0%-77.8%) in the internal cohort. The predicted thrombi length and volume were correlated with those of expert-contoured thrombi (r = 0.88 and 0.87, respectively; P < .001). When the derived deep learning model was applied to the external data set, the model obtained similar results in patients with large-vessel occlusion regarding the Dice coefficient (66.8%; interquartile range, 58.5%-74.6%), thrombus length (r = 0.73), and volume (r = 0.80). The model also obtained a sensitivity of 94.12% (32/34) and a specificity of 97.96% (48/49) in classifying large-vessel occlusion versus non-large-vessel occlusion. CONCLUSIONS The proposed deep learning method can reliably detect and measure thrombi on NCCT and CTA in patients with acute ischemic stroke.

Abstract
Background Carotid artery stenting (CAS) has emerged as a less invasive alternative to carotid endarterectomy (CEA) for the prevention of future cerebrovascular events in patients with carotid artery stenosis. Despite multiple randomized controlled trials (RCTs) comparing CAS and CEA for carotid disease, real-world data outside the rigorous environment of trials is scarce. Methods The present study is a prospective observational study conducted at a tertiary care center, wherein all patients who underwent CAS between January 2007 and December 2019 were included. All patients were followed up for one year of the last enrolled patient at an interval of one, six, and 12 months and then yearly thereafter. The primary composite outcome was defined as a combination of periprocedural (until 30 days of procedure) major adverse cardiac and cerebrovascular events (MACCEs) and the long-term incidence of ipsilateral stroke. The secondary outcome included the rate of restenosis. Results A total of 115 patients (86 males and 29 females) (147 lesions) who underwent CAS between 2007 and 2019 were followed up for a median of 80.5 months. Seventy-seven (67.27%) patients were symptomatic, and 38/115 (33%) were asymptomatic. Periprocedural MACCEs were noted in six patients, and four patients had ipsilateral stroke on long-term follow-up; hence, the primary composite outcome was observed in 10 (8.7%) patients. Higher age was found to be significantly associated with the primary composite outcome (p-value = 0.005). Five (4.34%) patients were lost to follow-up, while four (3.48%) patients developed restenosis. Conclusion CAS is a safe and less invasive intervention in patients with significant carotid artery stenosis and is equally effective in preventing future strokes. The incidence of primary outcome rises with an increase in age.

Abstract
Background A recent increase in migration both inside Europe and from non-European countries has expanded the language profile of many European countries. As a result, there has been a significant increase in barriers to healthcare access experienced by linguistic minority migrants. This systematic review aims to explore language barriers in primary care, focusing on the experiences of linguistic minority migrants living in Europe. Methods PubMed, Embase, Scopus and Global Health were searched to identify studies published in English until May 2021. Qualitative and mixed methods studies on either linguistic minority migrants or healthcare workers working with linguistic minority migrants, exploring the impacts of language barriers in a primary care setting published were eligible. The studies were analysed using a Braun and Clarke's thematic analysis approach. Quality of the studies were assessed using the Mixed Methods Appraisal Tool. Results 16 studies from 14 different European countries were eligible. Participants in the studies included four groups: linguistic minority migrants (n = 11), healthcare workers (n = 10), interpreters (n = 1) and administrative staff (n = 1). Barriers identified included a lack of interpreters, limited cultural competence of practitioners, a lack of practitioner training and knowledge, a lack of accessible information for migrants, difficulties expressing emotions and building patient-practitioner relationships, and risks to women's bodily autonomy resulting from language barriers. Conclusions Linguistic minority migrants living in Europe face a number of barriers when accessing primary care. These barriers can risk patient safety, reduce the likelihood of seeking healthcare services, and impact patient experiences of healthcare services. There is a need for improved interpreter services, practitioner training, and information accessibility for both migrants and healthcare staff. Key messages • Linguistic minority migrants experience significant barriers to primary healthcare access across Europe. • There is a need for improved interpreter services, practitioner training, and information accessibility for both migrants and healthcare staff.

Abstract
Background Heart Failure with reduced Ejection Fraction (HFrEF) is a common disorder affecting a large population. Iron deficiency (ID) with and without anaemia is an important variable which is often underreported and under treated in clinical practice, which contributes to patient symptoms. The present study was undertaken to study the prevalence and Spectrum of Iron Deficiency in patients of HFrEF. Methods This is a single-centre observational study. All patients with a clinical diagnosis of HFrEF presenting to the hospital were studied. Ejection Fraction (EF) was assessed on Echo and ID was diagnosed on basis of serum ferritin <100 micro g/dl or serum ferritin 100-300 micro g/dl with low Transferrin Saturation (TSAT) (< 20%). Results We have studied a total of 204 patients with a predominantly male population (73%) and a mean age of 62.88 years. Most of our patients were in mid-level functional class (mean 2.48 ± 0.50) and had low EF (mean 29.56 ± 6.52). Out of 204 patients, 88.7% patients had ID with 83% patients having absolute ID. Of the total patients with HF, 70% had anaemia. Amongst those with anaemia 93% had ID, and even without anaemia, 68% had absolute or functional ID, underlying the importance of evaluating iron status in all patients of HF irrespective of their haemoglobin levels. Conclusion This study highlights the burden of iron deficiency in heart failure patients in the Indian population and opens the way for large scale studies for better characterization of iron deficiency as well as therapeutic trials in the management of heart failure patients.

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO's and Advanced Virgo's Third Observing Run. PHYSICAL REVIEW LETTERS 2022; 129:061104.

Abstract
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 M_{⊙} and 1.0 M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14 yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200] Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2 M_{⊙}<m_{PBH}<1.0 M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1 M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Abstract
Abstract
Study question
Does adding gonadotropin-releasing hormone agonist (GnRHa) to hCG trigger increases the number of high-grade embryos in GnRH antagonist protocol in fresh non-donor IVF?
Summary answer
Final oocyte maturation triggered by dual trigger increases the number of MII oocytes thus transferring good-quality embryos and cryopreserving surplus embryos compared to hCG trigger.
What is known already
hCG has been conventionally used as a ‘faux’ LH surge to bring about final oocyte maturation due to structural similarity between the two. GnRH agonist, on the other hand, induces a more physiological gonadotropin surge for follicular maturation, but is associated with luteal phase deficiency. Recent studies have shown that combining GnRHa with hCG trigger improves oocyte maturation and embryo quality with the added benefit of a luteal phase support, thereby improving IVF outcomes in terms of both embryological and reproductive outcomes.
Study design, size, duration
A single-center, open labelled, randomized controlled trial including 100 normal responder patients between 21-38 years undergoing IVF using GnRH antagonist protocol between January 2020 to August 2021. The study excluded patients with the presence of other variables of adverse outcomes like diminished ovarian reserve (AFC < 5 or AMH < 1.2 ng/ml), endocrine disorders, thin endometrium (<6mm), previous history of uterine surgeries, and high responders.
Participants/materials, setting, methods
100 patients undergoing fresh IVF cycle using GnRH antagonist protocol were randomized after informed consent to receive either dual trigger (Leuprolide acetate 1 mg + rhCG 250 mcg, n = 50) or single hCG trigger (rhCG 250 mcg, n = 50). Oocyte retrieval was done 35-37 hours after trigger followed by IVF/ICSI, as indicated. Oocyte and embryo grading was done using Istanbul consensus. Analysis was done by ITT. Outcomes were analyzed using Independent t-test and Chi-square test.
Main results and the role of chance
The baseline characteristics were comparable in both arms. the number of MII oocytes retrieved (7.82 versus 5.92, p = 0.003) and the number of day-3 grade-1 embryos (4.24 versus 1.8, p < 0.001) were higher in the dual trigger group, whereas fertilization rates between the two groups (91.82% versus 88.51%, p=NS) were comparable. Consequently, the number of embryos cryopreserved (2.68 versus 0.94, p < 0.001) were significantly higher in the dual trigger group. However, the implantation rate between the two groups (21% versus 19.6%, p = 0.770) was comparable. The serum LH levels 12 hours post trigger were measured in both the arms and as expected, high serum LH values were documented in the dual trigger group (46.23 mIU/ml vs 0.93 mIU/ml, p < 0.0001).
Limitations, reasons for caution
Due to the impact of the Covid-19 pandemic causing an intermittent pause in IVF services at our center, a smaller sample size of 100 patients could be enrolled in the study, and reproductive outcomes in terms of live births and cumulative live births could not be assessed
Wider implications of the findings
This study, though small, has contributed to some evidence of redesigning the dual trigger in all antagonist cycles, with the exception of high responders and PCOS patients. The addition of GnRHa to hCG trigger has led to the possibility of cryopreserving surplus embryos thereby increasing the cumulative live births.

Abstract
Study question
To compare role of intra-ovarian platelet rich plasma (PRP) versus marrow derived stem cell (SC) instillation for improvement in ovarian reserve (AFC, AMH and FSH)
Summary answer
Both PRP and SC therapy improves the ovarian reserve however, response to PRP is superior to SC post intervention
What is known already
With increasing incidence of females with diminished ovarian reserve (DOR), posing a serious challenge in terms of limited treatment options for these couples. Clinicians are trying to find effective strategies besides oocyte donation or adoption Of late, novel ovarian rejuvenation approaches has been investigated which are currently available for research purposes only. Multiple studies are evaluating effect of intra-ovarian PRP or autologous SC instillation, the results are encouraging as they are showing improvement in ovarian reserve thus bringing a paradigm shift in treatment options. None of the published studies so far have compared PRP versus SC in DOR population.
Study design, size, duration
A prospective comparative study was conducted at Division of Reproductive Medicine of a tertiary care institute. 72 infertile females (20-39 years) with poor ovarian reserve (AMH <1.2 ng /ml; AFC<5) were enrolled in the study between January 2020 to December 2021. The two comparative groups underwent either intra-ovarian PRP instillation (n = 42) or autologous SC transplantation (n = 30).
Participants/materials, setting, methods
After the two groups were matched (PRP vs SC) for baseline characteristics (Age, AMH, AFC, FSH, Estradiol), 30 subjects in each group were compared for change in serum FSH/AMH/Estradiol levels, AFC, right and left ovarian volume at 1st month and 3rd month post intervention from the baseline. This was also compared between the two groups using Student t-test. The cost and procedural pain measured using Visual analog scale (VAS) were also compared between the groups.
Main results and the role of chance
After matching for baseline characteristics, significant ∼ 1.8/2 and ∼1.5/1.6 fold increase in AFC at 1st/3rd month post intervention (p<0.001) was observed after PRP instillation and SC transplantation respectively. This significant improvement was observed more in PRP group than SC group at 3rd month post intervention (7.07 vs 5.60, p=0.02), while no significant difference existed at 1st month of follow up. However, there was no significant improvement in serum FSH, AMH and Estradiol levels (p0.05) from the baseline at 1st and 3rd month post intervention in both the groups. Similarly, there was no significant difference between the two groups in serum FSH level (7.98 IU/ml vs 9.62 IU/ml, p=0.062; 8.26 IU/ml vs 9.50 IU/ml, p=0.15), AMH level (1.62 ng/ml vs 1.02 ng/ml, p=0.27; 1.35 ng/ml vs 0.95 ng/ml, p=0.24), Estradiol level (49.12 pg/ml vs 56.48 pg/ml p=0.443; 54.7 pg/ml vs 61.12 pg/ml, p=0.44), right ovarian volume (3.13 cm3 vs 2.49 cm3, p=0.06; 3.37 cm3 vs 2.74 cm3,p=0.063) and left ovarian volume (2.98 cm3 vs 2.47 cm3, p=0.102; 2.87 cm3 vs 2.34 cm3,p=0.103) at 1st and 3rd month post intervention respectively. PRP was more cost-effective and associated with less pain (32.5 mm vs 28.13 mm, p=0.02), and better patient compliance.
Limitations, reasons for caution
This was a comparative study and the participants were not randomized but were matched for the baseline characteristics. Also due to impact of Covid-19 causing intermittent pause in nonessential facilities like IVF services, a smaller sample size could be enrolled and also clinical outcomes could not be evaluated
Wider implications of the findings
This study, although comparative, for the first time highlights the beneficial role of PRP over SC, thus can establish superiority of PRP as minimally invasive, economical, patient friendly and a recommended therapy for ovarian rejuvenation and folliculogenesis, providing the DOR females an opportunity to produce their own offspring.

Abstract
Abstract
Study question
Does intra-ovarian instillation of platelet rich plasma (PRP) improves the clinical outcome of IVF cycles in women with Diminished Ovarian reserve (DOR)?
Summary answer
PRP instillation leads to consistent improvement in Antral follicle count (AFC), thus achieving clinical pregnancy rate of 33.3% per cycle in women with DOR.
What is known already
There is rising incidence of females with diminished ovarian reserve (DOR) especially among Asian ethnicity. With the emergence of regenerative medicine, multiple studies have evaluated the role of intra-ovarian PRP, demonstrating a beneficial role in improving ovarian reserve parameters (serum Follicular stimulating hormone (FSH), serum anti-Mullerian hormone (AMH), AFC). Despite its’ favorable effects on biochemical markers and AFC, data regarding improvement in clinical outcome remains elusive and led to inception of this study.
Study design, size, duration
A prospective interventional study was conducted at Division of Reproductive Medicine of a tertiary care institute. 41 infertile females aged 20-39 years with DOR (AMH <1.2 ng /ml; AFC<5) were enrolled in the study during a 6-month period beginning from August 2021.
Participants/materials, setting, methods
After informed consent, patients received fresh autologous PRP, prepared from 30 ml venous blood. 1.5ml of PRP instilled in each ovarian stroma between day 7-10 of menstrual cycle under sedation. Patients were followed up for three-consecutive months to assess ovarian reserve parameters including serum FSH, AMH and AFC. Patients showing significant improvement in parameters were recruited for fresh IVF cycles using Antagonist protocol with 1% transdermal testosterone. Outcomes were analysed using linear mix effect model.
Main results and the role of chance
The average platelet concentration in PRP was ∼10,00,000 platelets/µL. The mean age of enrolled patients was 31.22±4.16 years. Linear improvement in AFC (3.63 vs 6.98 vs 7.97 vs 6.90, p<0.001) was observed from baseline to three consecutive follow-up months with maximal response witnessed in second month in 57.1% of those undergoing IVF cycle. However, there was no significant difference in Serum FSH (p=0.11) and AMH (p=0.16) from the baseline post intervention. Of the 41 patients, 35 (85.3%) responded to the treatment and underwent IVF antagonist cycle. 5 out of 35 IVF cycles were cancelled mid-cycle due to poor ovarian response. The mean dose of gonadotropin requirement was 2667.5±281.1 IU (Follicular stimulating hormone) and 1400±337.3 IU (Human menopausal gonadotropin). The average number of oocytes retrieved was 5.7±2.2 whereas mean number of MII oocytes was 4.63±1.85. The fertilization rate and the cleavage rate were 92.4% and 74.1% respectively. Of the thirty patients, eight patients underwent day 2 transfer due to poor grade of embryos. Mean number of grade 1- day 3 embryos was 1.25±0.55 with surplus embryos available for cryopreservation in 14 patients. The overall clinical pregnancy rate per transfer was 33.33%. No adverse events were reported.
Limitations, reasons for caution
This was a prospective single arm study. A randomized controlled trial comprising a “no-treatment” arm would establish a Level-I evidence. However, “no-treatment” arm in a developing country like ours, imposes financial burden on the couple with no guaranteed clinical success and thus raising ethical concern and need for ovarian rejuvenation.
Wider implications of the findings
With the impetus to provide a biological child to these DOR women, intra-ovarian PRP instillation as a method of ovarian rejuvenation holds promising results. Evidently, PRP is not only effective in improving ovarian reserve but this translates into an improved reproductive outcome in a population, previously limited to oocyte donation.

Abstract
Abstract
Study question
Does sperm affect the implantation and early embryogenesis?
Summary answer
Deranged sperm genomic integrity, limited repair mechanisms, aberrant gene expression have the potential to be transmitted to developing embryo and affect implantation and embryonic development.
What is known already
The terminally differentiated, transcriptionally quiscent sperm cells are vulnerable to a host of factors which might affect its function. The spermatozoa with truncated repair mechanisms have the potential to fertilize the oocyte, but eventually result in high rates of pre and post implantation losses. Oxidative stress, deranged genomic integrity, aberrant gene expression in the sperm cell has the potential to affect fertilisation potential, implantation and embryonic viability. This has been seen to be correlated with decreased fertilisation, clevage rates and blastocyst development and thus impaired implantation rates.
Study design, size, duration
A case control study of 75 men from infertile couples who had recurrent implantation failure (RIF) in IVF cycles and 75 fertile controls at AIIMS, New Delhi, India. Study duration was 2 years.
Participants/materials, setting, methods
Semen samples from men from couples who had RIF were analyzed as per WHO 2010. Sperm reactive oxygen species (ROS) and DNA fragmentation index (DFI) was assessed by chemiluminiscence and sperm chromatin structure assay (SCSA) respectively. Relative sperm telomere length was evaluated from sperm DNA by q-PCR analysis. The expression of genes pertinent for early embryonic development was done by qPCR. The relative quantification was done after normalizing with GAPDH and β-actin by 2-ΔΔCt method.
Main results and the role of chance
Seminal ROS levels (RLU/sec/million sperm) were seen to be significantly higher [57.75 (10.1-1186.9)] in cases with respect to controls [16.7(1.15-53.9)] (p < 0.001***). The mean DFI of men undergoing ART was significantly higher (37.7 ± 5.7) vs 23.2 ± 4.6%; p < 0.001***) in cases as compared to controls. ROS and DFI levels correlated negatively with sperm concentration and progressive motility (p < 0.001***). We analyzed the expression of FOXG1, SOX3, STAT4, RPS6, RBM9, RPL10A, RPS17, RPL29, WNT5A, HSP90, TOMM7, EIF5A genes. The expression of SOX3, RBM9, WNT5A, HSP90, TOMM7, and EIF5A showed a significant difference from control levels. The relative sperm telomere length was found to be significantly lower in RIF patients as compared to controls (p < 0.001***).
Limitations, reasons for caution
The current study was a case control study and lacked randomization and also is limited by low sample size. There is a lack of stratification in the enrollment of participants due to difference in specific risk of occurrence and varied clinical history.
Wider implications of the findings
The analysis of spermatozoal gene expression is important for understanding the sperm differentiation, fertilization and early embryonic events. Correlation with oxidative stress, genomic integrity and telomere length may help in regulationof gene expression. It may help in establishing sperm gene expression as a potential biomarker.

Abstract
Study question Does immune response to COVID-19 vaccination affect the clinical outcome in fully vaccinated infertile women undergoing IVF/ICSI cycles? Summary answer COVID-19 IgG antibodies are present in follicular fluid post vaccination and higher immune response increases duration of gonadotrophins required and negatively impacts the IVF outcome. What is known already Recent studies assessed the influence of COVID-19 infection and mRNA COVID-19 vaccine on the stimulation cycle characteristics and embryological variables of patients undergoing IVF cycle and found no effect on the IVF outcome in their immediate IVF cycle after recovery, except for a decreased number of top quality embryos. One study reported infection or mRNA vaccine results in rapid formation of anti-COVID IgG which can be detected in follicular fluid. This immune response did not lead to any significant negative effect on ovarian follicular function. There is a possibility that COVID-19 infection might affect numerous fertility-linked proteins. Study design, size, duration Prospective observational study, conducted at Division of Reproductive Medicine of tertiary care institute. After taking informed consent, 32 patients who satisfy the inclusion and exclusion criteria with history of receiving two doses of Covishield or Covaxin vaccine with at-least 2 weeks from last dose, were recruited for IVF/ICSI cycles from December 2021 to January 2022, for assessing COVID-19 IgG antibodies in their follicular fluid. Participants/materials, setting, methods Women of 21-40 years with normal ovarian reserve and normal uterine cavity were included, those with history of COVID infection were excluded. All patients underwent GnRH antagonist protocol. Follicular fluid was collected at time of oocyte retrieval. After collecting oocytes, 400 microlitre of follicular fluid was stored at -80 and later thawed and analysed for SARS-CoV-2 IgG antibodies (ADVIA Centaur COV2G assay, Germany) which are expressed in index value and reported as reactive (≥1 index). Main results and the role of chance Out of 32, 21 (65.6%) of the participants had received COVISHIELD (V1)and 11 (34.3%) received COVAXIN (V2). The mean gap between vaccine and the IVF cycle was 84.94 ± 52.65 days. The mean COVID IgG antibody titres (Index) were significantly higher in V1, 28.77±33.50 (0.34 -100), than V2 2.28±3.74(0.05-13.23), p<0.001. Patients with higher antibody titres, required longer duration of ovarian stimulation, rho=0.42, p = 0.017. Patients with higher COVID IgG antibodies were negatively correlated with clinical pregnancy rate (20.9 0± 29.68 vs 4.60 ± 6.28, p = 0.153). The time gap from the last dose of vaccine to IVF cycle had moderate negative correlation with percentage of grade-I embryos out of the total embryos fertilised (%), rho= -0.33, p = 0.068. Furthermore, higher gonadotropins doses were required in patients with high antibody titres, rho=0.25, p = 0.160, and amongst V1 vs V2, total dose of gonadotropins required was 3802.38±742.92 vs 3422.73±564.52, respectively, p=0.115. COVID IgG antibody titres had weak negative correlation with number of grade-I embryos, rho= -0.16, p = 0.396. The time gap from the last dose of vaccine to IVF cycle had a weak negative correlation with number of grade-I embryos, rho=-0.28, p = 0.124. Limitations, reasons for caution The main limitation of this study is small sample size. However, the study is currently ongoing, and these are the interim results of the same. As prospective studies with larger sample size would be required to assess the effect of different COVID-19 vaccines in different populations on the IVF outcomes. Wider implications of the findings The present study confirms the presence of COVID IgG antibodies in follicular fluid in vaccinated women, and proves that COVISHIELD vaccinated patients had higher antibody titres. Higher antibody titres require longer duration of stimulation and result in poorer outcomes so a longer interval from vaccine to IVF should be recommended. Trial registration number NA

Abstract
Study question
What is cut-off value for peripheral and uterine natural killer (pNK, uNK) cells and any correlation between them in fertile and RIF women?
Summary answer
Cut-off values were 7% for uNK and 11.6% for pNK in fertile controls. No significant correlation observed among fertile and infertile women with RIF.
What is known already
Association of uNK and pNK cells with infertility is debatable. It is not clear whether measuring NK cell levels in RIF has a role. pNk cell levels however has been used in various studies to guide the need of immunotherapy in RIF women. Definition of normal range of uNK cell numbers has also not been stated clearly because of lack of standardised protocol. Literature reveals the cut off values for pNk cells to be 12% or 18% and for uNK cells between 5-12.9%. Correlation between uNK and pNK cells in fertile or RIF women has not been studied earlier.
Study design, size, duration
A prospective study was conducted at ART Centre, Department of Obstetrics and Gynecology at tertiary care institute during a period from January 2019 to January 2021. Thirty women with RIF and fifty fertile controls with age <35 years having regular menstrual cycles and no hormonal treatment in last 3 months were enrolled in the study for uNK and pNK cell testing. The permission was obtained from the Institute Ethics Committee.
Participants/materials, setting, methods
Subjects included women with RIF with age 20-35 years, tubal and unexplained factors, normal ovarian reserve, normal karyotype and normal uterine cavity. In both subjects and controls, midluteal endometrial biopsy sample was taken for Immunohistochemistry staining of CD 56+ cells to determine uNK cells. Peripheral venous blood was also obtained at the time of biopsy for flow cytometry in peripheral blood mononuclear cells to determine pNK cells. Cut off values were derived from fertile controls.
Main results and the role of chance
The mean age and BMI were comparable between fertile control and study group(29.45±3.3 vs 31.17±3.3 years, 22.97±1.89 vs 23.21±2.2 kg/m2; p-value >0.05). The control group had median value of 7% for uNK cell levels and 11.6% for pNK cell levels. In RIF subjects, the median value for uNK cells was 13.5% and even though higher compared to controls it was not statistically significant(p-value >0.05) . The median pNK values were comparable among controls and RIF group (11.6% vs. 12%). All RIF subjects did not have elevated NK cell levels. 18 (60%) subjects had elevated uNK cell levels (more than 7%) whereas 40% had below the reference value. pNK cells were also elevated in only 53.3% of subject population. There was positive correlation found between uNK and pNK cell levels in RIF subjects, however it was not statistically significant (r 0.312, p-value 0.09). In fertile controls, there was insignificant negative correlation between uNK and pNK cell levels (r -0.231, p-value 0.33).
Limitations, reasons for caution
The small sample size is the foremost limitation of study.
Wider implications of the findings
uNK cell testing may be worthwhile in women with unexplained RIF so as to guide immunotherapy to improve pregnancy outcomes. As no significant correlation has been found between pNK and uNK cells in fertile and RIF women, pNK cell testing in RIF women may be done with caution.

Abstract
BackgroundRecently, it has been recognized that frailty and pre-frailty are common in patients with rheumatoid arthritis (RA) [1]. Whether frailty status portends an increased risk of adverse outcomes in patients with RA on biologic or targeted synthetic disease modifying anti-rheumatic drugs (b- or tsDMARDs) remains unknown.ObjectivesTo evaluate the association between frailty and adverse outcomes in patients with RA exposed to b- or tsDMARDs.MethodsUsing the IBM/Watson MarketScan Commercial Claims and Encounters Databases, we identified all patients with RA who filled new prescriptions (or received infusions) for TNFα antagonists (TNFi), non-TNFi biologics (rituximab, abatacept, tocilizumab) or Janus Kinase inhibitors (JAKi) between 2008-2019. We used a 1-year lookback period without the use of these drugs to identify new users. The date of the first prescription within these three drug categories was the index date. Patients’ frailty risk score was calculated using the Claims-Based Frailty Index (CFI) [2], which estimates a deficit-accumulation frailty index using International Classification of Diseases codes, Current Procedural Terminology codes, and Healthcare Common Procedure Coding System codes in administrative claims data in the 1-year baseline period. The index ranges from 0 (not at all frail) to 1 (severely frail). The primary outcome was time to serious infections (those requiring hospitalization); secondary outcomes: any infection (outpatient or inpatient encounters) and all-cause hospitalizations.Patients were followed until 1) outcome occurrence; 2) disenrollment; 3) >90 days elapsed (or >180 days for rituximab) without further fills of the first drug categories; 4) they filled/received infusions of b-/tsDMARDs from a different drug category; or 5) 2 years after index. Cox proportional hazards adjusting for demographics, calendar year, serious and/or opportunistic infections in the 12-months prior to index were used to estimate the adjusted hazard ratios (aHR) and 95% confidence intervals (CIs) for each outcome. In separate model, we additionally adjusted for comorbidity burden, and health care utilization (HCU).ResultsA total of 62,246 patients with RA met our inclusion criteria of whom 50,910 (82%) started TNFi as their first biologic, 9525 (15%) non-TNFi biologics, and 1811 (3%) JAKi. Among these, 3928 (6%) were considered frail. In multivariable analyses, frail patients had higher risk of serious infections compared to non-frail patients (aHR 2.37, 95% CI 2.05-2.74) which decreased to aHR 1.34, 95% CI 1.13-1.58 (Table 1) after adjusting for comorbidity burden and the HCU. Similarly, frailty was associated with increased risk of any infection (aHR 1.18, 95% CI 1.11-1.25), and all-cause hospitalizations (aHR 1.34, 95% CI 1.21-1.49) relative to non-frail individuals.Table 1.Multivariable models evaluating the association between frailty status and inpatient infections as the outcomeVariable#Hazard Ratio (95% Confidence Interval)@Hazard Ratio (95% Confidence Interval)Frail2.37 (2.05, 2.74)1.34 (1.13, 1.58)#Model adjusts for age, sex, major infection requiring inpatient admission in 12 months prior, concomitant baseline drugs such as csDMARDs, glucocorticoids, NSAIDs and opioids@Model additionally adjusts for Chalrson comorbidy score and healthcare utilizationConclusionFrailty is an important predictor for the risk of adverse outcomes among patients with RA treated with b- or tsDMARDs.

Abstract
BackgroundBiologic therapies used in the management of rheumatoid arthritis (RA) target several cytokines that have been implicated in the pathogenesis of multiple myeloma (MM). Yet little is known about the association between use of biologic or targeted synthetic disease modifying anti-rheumatic drugs (b or tsDMARDs) in RA and the incidence of MM.ObjectivesOur objective was to estimate the association between b/tsDMARD use and the risk of MM among persons with RA using Veterans Health Administration (VHA) data. We hypothesized that b-/tsDMARD use is associated with a lower incidence of MM compared with conventional synthetic DMARDs (csDMARDs).MethodsIn this retrospective cohort study, we identified patients >18 years of age diagnosed with RA in any United States VHA facility from 1/1/2002 and 12/31/2018. All patients met the following inclusion criteria: 1) two or more International Classification of Diseases Version 9 or 10 (ICD9 or ICD10) codes for RA at least 7 days apart but no more than 365 days apart 2) a prescription for a csDMARD within 90 days of the first RA diagnosis 3) one inpatient or outpatient visit 30 days to 2 years preceding first RA diagnosis (indicating a regular user of VHA). Medication data was derived from the outpatient prescription fills, bar coded medication administration (BCMA), and intravenous (IV) data domains. The csDMARDs included in these analyses were: methotrexate, sulfasalazine, leflunomide, and hydroxychloroquine. The bDMARDs included were tumor necrosis factor inhibitors (TNFi) and non-TNFi biologics such as tocilizumab, rituximab, abatacept, and biosimilars; tsDMARD was tofacitinib. Patients with MM before the diagnosis of RA were excluded. Incident MM was determined by 1 or more ICD9/10 code or ICD-oncology codes. Multivariable Cox proportional hazards model were performed to estimate the hazard ratio for developing MM among those during and following the use of a b-/tsDMARD relative to b-/tsDMARD-naïve persons adjusting for age, gender, race, and ethnicity.Results27,540 veterans with RA met study eligibility criteria, of whom 8,322 (30%) had taken a b-/tsDMARD. Over the study period there were 77 incident MM over a total of 192,000 person years. There were 55 events in users of csDMARDs, an incidence rate (IR) of 0.40 (95% CI 0.30-0.52) per 1000 person-years and 22 in persons currently or formerly using b-/tsDMARDs (IR 0.41, 0.25-0.61 per 1000 person years). The unadjusted hazard ratio for MM following bDMARD use relative to csDMARD only use was 1.04 (0.63, 1.73), which increased to 1.28 (0.76, 2.16) after adjusting for demographic characteristics (Table 1).Table 1.Multivariable Cox proportional hazards model for association between use of disease modifying anti-rheumatic drugs and incident multiple myeloma.Clinical characteristicHazards ratio (95% CI)csDMARDReferenceb-/tsDMARD use1.28 (0.76-2.16)Age*1.04 (1.02-1.07)Female0.58 (0.20-1.62)RaceReferenceWhite2.11 (1.15-3.86)Black0.70 (0.10-5.08)OtherHispanic Ethnicity0.71 (0.17-2.92)Abbreviations: b-/tsDMARD- biologic or targeted synthetic disease modifying anti-rheumatic drug; CI: confidence interval*Hazards ratio reflects risk per every 1-year increase in ageModel adjusted for age, gender, race, and ethnicityConclusionIn this nationwide VA study, we did not observe an association between bDMARD use and the incidence of MM. Of note, the median interval from initiation of a bDMARD to the end of follow-up was approximately 5.8 years, which does not allow for an examination of a possible longer term influence.Disclosure of InterestsNone declared

Abstract
The ongoing COVID-19 pandemic is a major public health crisis. Despite the development and deployment of vaccines against SARS-CoV-2, the pandemic persists. The continued spread of the virus is largely driven by the emergence of viral variants, which can evade the current vaccines through mutations in the Spike protein. Although these differences in Spike are important in terms of transmission and vaccine responses, these variants possess mutations in the other parts of their genome which may affect pathogenesis. Of particular interest to us are the mutations present in the accessory genes, which have been shown to contribute to pathogenesis in the host through innate immune signaling, among other effects on host machinery. To examine the effects of accessory protein mutations and other non-spike mutations on SARS-CoV-2 pathogenesis, we synthesized viruses where the WA1 Spike is replaced by each variant spike genes in a SARS-CoV-2/WA-1 infectious clone. We then characterized the in vitro and in vivo replication of these viruses and compared them to the full variant viruses. Our work has revealed that non-spike mutations in variants can contribute to replication of SARS-CoV-2 and pathogenesis in the host and can lead to attenuating phenotypes in circulating variants of concern. This work suggests that while Spike mutations may enhance receptor binding and entry into cells, mutations in accessory proteins may lead to less clinical disease, extended time toward knowing an infection exists in a person and thus increased time for transmission to occur.

Abstract
BackgroundRecruitment of candidates is a cost- and effort-intensive aspect of rheumatology fellowship programs. For program leaders to efficiently use the available resources and improve recruitment outcomes, it is imperative to understand the attributes that influence the candidates’ choice of a program. Previous studies have examined the type and relative importance of the factors that candidates use in selecting other fellowship programs (1, 2). However, no such studies have been conducted in the field of rheumatology.ObjectivesTo examine the factors that influence the selection of fellowship programs by rheumatology applicants.MethodsAn anonymous, web-based survey comprised of 13 questions was shared with rheumatology fellowship applicants on messaging applications and online forums. The survey was open from 10/29/2021-11/06/2021. Participation was voluntary and informed consent was implied through the participants’ response. Three reminders to complete the survey were sent. Four domains of the applicant’s perception in relation to their preference of ranking rheumatology programs were assessed: (1) program prestige, (2) program structure, (3) interview day experience, and (4) career path of the alumni. The survey questions were devised in one of the following formats: (1) 5-point Likert scale, (2) rank order questions, (3) yes/no questions, (4) multiple choice questions, and (5) open-ended questions.ResultsThirty-two rheumatology applicants responded to the survey. The prestige of the program was reported to be extremely important by 16%, very important by 19%, somewhat important by 44%, and little or not important by 21% responders. The opportunity to see a diverse patient population was reported to be important by 97% respondents. The call schedule and higher number of fellows were considered important by 88% of the respondents. 66% preferred programs with higher number of faculty members. 69% favored programs with an ultrasound curriculum. The availability of clinician-educator track (18%), MCR/MPH (14%), and T32 grand (4%) were considered less important. 69% reported that the opportunity to train at a Veterans Administration hospital did not influence their choice. Regarding interview day experience, interaction with the faculty (63%) and the fellows (17%) were considered important factors influencing program ranking. Respondents preferred programs with alumni in academic clinician track (45%) and private practice (43%) compared to programs with alumni in academic research (13%) or industry pathway (4%). The geographical location of the program including the cost of living and location of significant others also influenced the applicants’ choice.ConclusionTo the best of our knowledge, this is the first survey to assess the attributes that influence a candidate’s choice of a rheumatology fellowship program. Our survey demonstrated that a positive interview day experience and program attributes including the opportunity to interact with a diverse patient population, relaxed call schedule, higher number of fellows and faculty, the presence of an ultrasound curriculum, and the location were the dominant factors influencing applicants’ choice of a program. The main limitation of our study is the lack of generalizability due to selection bias. Understanding the factors involved in decision making of the rheumatology fellowship applicants can provide valuable information for both the applicants and the programs and therefore lead to a better match.References[1]Kelm DJ, Skalski JH, Nelson DR, Kashani KB, Lee AS, Wesselius LJ, et al.

Abstract
Summer internships serve important roles in training the next generation of biomedical researchers and healthcare providers through laboratory and clinical experiences that excite trainees about these fields and help them make informed decisions about career paths. The SARS-CoV-2 (COVID) pandemic and associated physical distancing restrictions precluded implementation of traditional in-person summer curricula and led to the cancellation of many internships across the USA. COVID-related disruptions also created opportunities for trainees to engage in remote research, become proficient in online learning platforms, and explore multidisciplinary topics. These skills are highly relevant to trainees as virtual interfaces occupy an increasingly mainstream role in their professional paths. The response to the COVID pandemic required real-time adaptations at all levels for major biomedical institutions including the University of Maryland Baltimore (UMB). Pivoting summer programs to a virtual format as part of this response provided a "teachable moment" to expose trainees to the innovation and resilience that are essential components of the biomedical profession. UMB summer programs, which span diverse biomedical disciplines from cancer research to diabetes, consolidated resources and identified mentors with online research projects to develop a robust virtual curriculum. Herein, data from a cancer-focused internship illustrate the collaborative adaptations to established components and creation of new learning modules in the transition to, and implementation of, online training. Outcomes are presented in the context of the COVID pandemic and significant societal issues that arose in the summer of 2020. The utility of virtual components and their impact on future programs is discussed.

Abstract
BackgroundEpidemiologic studies suggest that disease duration and degree of inflammatory activity of rheumatoid arthritis (RA) contribute to lymphoma development (1). Whether the decrease in inflammatory burden seen with use of biologic or targeted synthetic disease modifying anti-rheumatic drugs (bDMARDs or tsDMARDs) translates into a lower risk of lymphoma in RA needs to be studied.ObjectivesThe objective of our study was to examine the effect of administration of b/tsDMARDS on the incidence of lymphoma relative to conventional synthetic DMARDs (csDMARDs) in an inception cohort of Veterans with RA.MethodsWe identified patients >18 years of age diagnosed with RA in any US Veterans Affairs (VA) facility from 1/1/2002 and 12/31/2018 using the VA Corporate Data Warehouse (CDW). To be included, each patient was required to meet the following criteria: 2+ RA diagnostic codes at least 7 days apart but no more than 365 days apart; 2) a prescription for a csDMARD within 90 days of the first RA diagnosis; and 3) an inpatient or outpatient visit 30 days to 2 years preceding first RA diagnosis (indicating they are a regular user of the VA). The csDMARDs included in these analyses were: methotrexate, sulfasalazine, leflunomide, and hydroxychloroquine. The bDMARDs included were tumor necrosis factor inhibitors (TNFi) and non-TNFi biologics such as tocilizumab, rituximab, abatacept, and biosimilars; tsDMARD was tofacitinib. Patients with prevalent lymphoma were excluded. Lymphoma diagnoses were identified using International Classification of Diseases Version 9, 10 and Oncology (ICD9, ICD10, ICDO) codes.We used marginal structural models as described by Hernan et al (2) and time-varying Cox models to control for confounding by indication while evaluating this association. We adjusted for baseline demographics (age, sex, race, ethnicity, year of cohort entry, rheumatology visits), and time-varying CRP and time-varying Rheumatoid Disease Comorbidity Index (RDCI) (3) to control for confounding.Results27,421 Veterans with RA met our eligibility criteria. Most of the Veterans (56%) were in the age range 61-80 years old; 89% male, 76% White, 14% African American. 8,225 (30%) patients were treated with a b-/tsDMARD. The crude incidence rates were 1.71 (95% CI 1.5-1.94) per 1000 person-years for those only on csDMARDs and 1.78 (95% CI 1.44-2.18) for patients during or following use of a b/tsDMARDs. After adjustment with both time-fixed and time-varying covariates using marginal structural models, the incidence of lymphoma was not different between patients who did and did not use a b/tsDMARD (hazard ratio=1.06, 95% CI= 0.82-1.37) (Table 1).Table 1.Estimates of Effect of bDMARD or tsDMARD use on Lymphoma relative to use of csDMARDsMarginal Structural Models; adjusted for:@Demographics1.04(0.80, 1.34)#Demographics + CRP1.06(0.82, 1.37)* per 1000 person-years@Demographics = age, gender, race, ethnicity, rheumatology visits, and year of cohort entry#Adjusts for CRP, baseline rheumatology visits (yes/no) and RDCI.CRP = C-Reactive Protein, RDCI = Rhematic Disease Comorbidity Index, CI = Confidence Interval, b/tsDMARD = biologic or targeted synthetic DMARD, csDMARD = conventional synthetic DMARDConclusionIn this large study using the nationwide VA data, we did not observe an association between the use of b/ts DMARDs and an increased risk of lymphoma.References[1]Baecklund E, Iliadou A, Askling J, Ekbom A, Backlin C, Granath F, et al.

Abstract
BackgroundMerkel cell carcinoma (MCC) is twice as likely to recur in immunosuppressed (IS) patients as in immunocompetent (IC) patients. Iatrogenic IS due to autoimmune disease (AD) may influence prognosis differently than intrinsic IS such as due to hematologic malignancy. Moreover, modification of IS medication may improve prognosis.ObjectivesOur objective was to evaluate the risk of MCC recurrence among patients with AD diseases relative to other immunosuppressive conditions among 762 MCC patients from an Institutional review board-approved registry.MethodsWe categorized patients into 3 groups: IS due to AD (ISAD); IS from other causes (lSnon-AD) such as hematologic malignancy, solid organ transplant, human immunodeficiency virus; or immune competent (n=31, 70, and 661 respectively). ISAD patients were subcategorized into rheumatoid arthritis (RA) (ADRA, n=13) vs. AD except for RA (ADnon-RA, n=18). Descriptive statistics were used to compare the features of different characteristics in each group. Kaplan-Meier survival curves were constructed to assess the cumulative incidence of recurrence in different patient groups. In order to estimate the associations between baseline patient characteristics and the risk of MCC recurrence, Fine and Gray regression models were used with death as a competing risk for recurrence. The multivariable models adjusted for age, sex, and extent of MCC at initial presentation.ResultsPatients with ISAD had lower stage disease (local disease: 58% vs. 36%, p = 0.003) and smaller primary tumors than ISnon-AD (<= 2 cm: 83% vs. 57%, p=0.023). After adjusting for age, sex, and stage, ISAD patients (ADRA and ADnon-RA) overall had a 54% higher recurrence rate (hazard ratio (HR): 1.54, p=0.21) than IC patients. In comparison, ISnon-AD group had a 165% higher recurrence rate (HR: 2.65, p<0.001) than IC patients (Figure 1). When considered separately, ADRA pts appeared to have a similar recurrence rate as IC pts (HR: 1.19, p=0.76) while ADnon-RA pts had a higher recurrence rate (HR: 1.83, p=0.16) relative to IC pts. At the time of MCC diagnosis, 80% (n=24) of AD pts were on IS medication including conventional disease modifying drugs, biologics, or oral steroids. After MCC diagnosis, 22% (5 patients) stopped all immunosuppressive medications. Among patients on biologics, 89% (8/9 pts) elected to stop the drug. Eleven pts with AD experienced recurrences. Our study was underpowered to demonstrate associations regarding use of a particular immunosuppressive medication and MCC recurrence.Figure 1.Cumulative incidence of Merkel cell carcinoma recurrence in different patient groups.AD = autoimmune disease; IS = immunosuppressed; RA = rheumatoid arthritis.There were 4/13, 8/18, 49/70, and 217/661 recurrences in the RA, ADnon-RA, other immunosuppressed, and not chronically immunosuppressed groups, respectively. Follow-up time ranged from 26 days to 16 years, with median follow-up times of 4.7 years, 1.6 years, 1.6 years, and 3.9 years for the RA, ADnon-RA, other immunosuppressed and not chronically immunosuppressed groups, respectively.ConclusionIn this cohort, pts with AD appeared to have a better prognosis than intrinsic IS, with RA conferring very little risk above that for immune competent pts.AcknowledgementsI have no acknowledgements to declare.Disclosure of InterestsNone declared

Abstract
The neutron inelastic scattering of carbon-12, populating the Hoyle state, is a reaction of interest for the triple-alpha process. The inverse process (neutron upscattering) can enhance the Hoyle state’s decay rate to the bound states of 12C, effectively increasing the overall triple-alpha reaction rate. The cross section of this reaction is impossible to measure experimentally but has been determined here at astrophysically-relevant energies using detailed balance. Using a highly-collimated monoenergetic beam, here we measure neutrons incident on the Texas Active Target Time Projection Chamber (TexAT TPC) filled with CO2 gas, we measure the 3α-particles (arising from the decay of the Hoyle state following inelastic scattering) and a cross section is extracted. Here we show the neutron-upscattering enhancement is observed to be much smaller than previously expected. The importance of the neutron-upscattering enhancement may therefore not be significant aside from in very particular astrophysical sites (e.g. neutron star mergers). The triple-alpha process plays a role in nucleosynthesis, in the formation of 12C. Here, the authors discuss the rate and role of the neutron upscattering phenomenon on the triple-alpha process in a multi-step process.

Abstract
PURPOSE OF REVIEW This narrative review aims to summarize advances in the field of small fiber neuropathy made over the last decade, with emphasis on novel research highlighting the distinctive features of SFN. RECENT FINDINGS While the management of SFNs is ideally aimed at treating the underlying cause, most patients will require pain control via multiple, concurrent therapies. Herein, we highlight the most up-to-date information for diagnosis, medication management, interventional management, and novel therapies on the horizon. Despite the prevalence of small fiber neuropathies, there is no clear consensus on guidelines specific for the treatment of SFN. Despite the lack of specific guidelines for SFN treatment, the most recent general neuropathic pain guidelines are based on Cochrane studies and randomized controlled trials (RCTs) which have individually examined therapies used for the more commonly studied SFNs, such as painful diabetic neuropathy and HIV neuropathy. The recommendations from current guidelines are based on variables such as number needed to treat (NNT), safety, ease of use, and effect on quality of life.

Abstract
Introduction
COVID-19 is associated with an increased risk of venous thromboembolism (VTE). We compared the incidence of VTE on a busy hip fracture unit during 2020 with previous years to identify factors that may have played a role in its development.
Methods
Data were retrospectively obtained by notes review for patients admitted with neck or shaft of femur fracture. This included baseline characteristics, comorbidities and operative risk factors for VTE.
Results
11 of 420 patients (2.6%) were diagnosed with VTE in 2020, compared with 25 of 2,115 patients (1.2%) between January 2015 and December 2019 (RR 2.2 [95% CI 1.1 to 4.5, p < 0.05]). Only one patient in 2020 had confirmed COVID-19. Retrospective data between 2015–2019 were incomplete, and so statistical analysis of demographic and operative risk factors was not conducted. Descriptive statistics show there were comparable proportions of smokers and malignancy in both groups, and the majority of patients in both groups received either mechanical or pharmacological VTE prophylaxis. A higher proportion of patients were independently mobile prior to admission in 2020 (72.7% vs 28%). There was a shorter interval to development of VTE in 2020 (mean 12 days in 2020 vs 25 days in 2015–2019).
Conclusion
Following hip fracture surgery patients were twice as likely to develop venous thromboembolism in 2020 than in the previous five years. There was also a shorter time to development of VTE. This was despite a higher reported level of premorbid mobility in 2020 in otherwise similar patient groups. We hypothesise that isolation due to the COVID-19 lockdown contributed to this result. This suggests a need for enhanced vigilance and prompt VTE prophylaxis in this vulnerable population in the event of further pandemic waves and lockdowns.

Abstract
BACKGROUND AND PURPOSE There are limited data on the prevalence and outcome of intracranial atherosclerotic disease in patients with low-risk transient or persistent minor neurologic events. We sought to determine the prevalence and risk factors associated with intracranial atherosclerotic disease in patients with low-risk transient or persistent neurologic events. MATERIALS AND METHODS Participants with available intracranial vascular imaging from the Diagnosis of Uncertain-Origin Benign Transient Neurologic Symptoms (DOUBT) study, a large prospective multicenter cohort study, were included in this post hoc analysis. The prevalence of intracranial atherosclerotic disease of ≥50% was determined, and the association with baseline characteristics and DWI lesions was evaluated using logistic regression. RESULTS We included 661 patients with a median age of 62 years (interquartile range, 53-70 years), of whom 53% were women. Intracranial atherosclerotic disease was found in 81 (12.3%) patients; asymptomatic intracranial atherosclerotic disease alone, in 65 (9.8%); and symptomatic intracranial atherosclerotic disease, in 16 (2.4%). The most frequent location was in the posterior cerebral artery (29%). Age was the only factor associated with any intracranial atherosclerotic disease (adjusted OR, 1.9 for 10 years increase; 95% CI, 1.6-2.5). Multivariable logistic regression showed a strong association between intracranial atherosclerotic disease and the presence of acute infarct on MR imaging (adjusted OR, 3.47; 95% CI, 1.91-6.25). CONCLUSIONS Intracranial atherosclerotic disease is not rare in patients with transient or persistent minor neurologic events and is independently associated with the presence of MR imaging-proved ischemia in this context. Evaluation of the intracranial arteries could be valuable in establishing the etiology of such low-risk events.

Abstract
Background Sex-based disparity exists in liver transplantation (LT) with women being disadvantaged at every stage of the process starting from assessment to post transplantation (Bryce et al., 2009). The reasons for this are multifactorial and include biological disparities, psychosocial, and allocation inequalities (Burra et al., 2013). Aims The purpose of this study was to identify differences in immediate or long-term complications post-LT by sex. Methods We analyzed 702 patients who underwent LT at the University of Alberta from 2002 to 2015. Patients aged < 18 years or requiring a repeat or multivisceral transplant were excluded. Renal dysfunction was defined according to the KDIGO criteria. Cardiovascular disease (CVD) was defined as hospitalization for or death from coronary artery disease, cardiac arrest or cerebrovascular disease. Results Male patients comprised 69% of the population. Time on the waitlist was similar for men (9.3 ± 11.7 months) and women (9.9 ± 12.3 months; p=0.57). Both sexes were comparable in age (males: 53 ± 10 years; females: 52 ± 11 years; p=0.19), MELD (males: 18 ± 9; females: 19 ± 10; p=0.16) and BMI (males: 27.7 ± 5.7 kg/m2; females: 27.3 ± 6.6 kg/m2; p=0.58). Women had lower creatinine pre-LT (males: 1.1 ± 0.60 mg/dL; females 0.96 ± 0.51 mg/dL; p<0.01). There were no differences in donor age, sex or BMI. Women had significantly longer hospital length of stay (males: 18 days [IQR: 11, 32]; females: 25 days [IQR: 14, 43]; p <0.001). There was no difference in risk of acute kidney injury (OR 1.4 [95% CI: 0.98, 2.1]; p=0.06), infection (OR 1.1 [95% CI: 0.8, 1.5]; p=0.52) or rejection episodes (OR 1.1 [95% CI: 0.8, 1.5]; p=0.74) following LT. Women had a higher risk of CKD post-LT (OR 2.3 [95% CI: 1.6, 3.2]; p<0.0001). There was no difference in de-novo diabetes (males: 22%; females: 16%; p=0.10), hypertension (males: 45%; females: 48%; p=0.41), dyslipidemia (males: 37%; females: 39%; p=0.67) and CVD (males: 20%; females: 19%; p=0.84) post-LT. Graft (males: 11.4 ± 0.4 years; females: 11.8 ± 0.5 years; p=0.32) and patient survival (males: 11.8 ± 0.4 years; females: 12.4 ± 0.5 years; p=0.18) were similar over a median follow up of 6.3 years [IQR: 3.5, 9.9]. Conclusions Women spend a longer time in hospital and are at an increased risk of CKD following LT. Despite these differences, overall graft and patient survival are comparable. Our data suggest the disparity between sexes likely exists pre-LT and females that undergo LT have similar outcomes to their male counterparts. ![]()
