A multi-lesional analysis of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia: a single-centre analysis.

AIM: To conduct a multi-lesional computed tomography (CT) analysis of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) patients to determine volumetric changes in lesions over 5 years. MATERIALS AND METHODS: A retrospective case-note review was undertaken to identify 16 patients with histological and radiological features of DIPNECH between 2012-2021. Area and volume were calculated for 17 sets of lesions identified on high-resolution CT. Clinical data were extracted from electronic patient records, which included demographic data, outpatient clinic letters, histology reports, and imaging reports. RESULTS: One hundred and twenty-eight lesions were identified in 16 patients (one male, 15 female) and followed-up annually over a median 1,985 days (range 1,450-2,290). At year 1 follow-up, lesion area ranged from 1-48 mm2, and lesion volume ranged from 8-18,380 mm3; lesion area ranged from 1-45mm2 and lesion volume ranged from 11-17,800 mm3 and year 5. Half (8/16) of the patients had concomitant typical carcinoid tumours and one patient had an atypical carcinoid tumour. No statistically significant correlation (p<0.05) was found between lesion cross-sectional area or volume and duration of follow-up (years and days). No metastatic spread was observed at the time of analysis. CONCLUSIONS: No significant increase was observed in the size of over 100 lesions in patients with DIPNECH over a 5-year period and no metastasis occurred during the study period affirming the relatively indolent course of the disease.

Circulating tumor DNA association with residual cancer burden after neoadjuvant chemotherapy in triple-negative breast cancer in TBCRC 030.

BACKGROUND: We aimed to examine circulating tumor DNA (ctDNA) and its association with residual cancer burden (RCB) using an ultrasensitive assay in patients with triple-negative breast cancer (TNBC) receiving neoadjuvant chemotherapy. PATIENTS AND METHODS: We identified responders (RCB 0/1) and matched non-responders (RCB 2/3) from the phase II TBCRC 030 prospective study of neoadjuvant paclitaxel versus cisplatin in TNBC. We collected plasma samples at baseline, 3 weeks and 12 weeks (end of therapy). We created personalized ctDNA assays utilizing MAESTRO mutation enrichment sequencing. We explored associations between ctDNA and RCB status and disease recurrence. RESULTS: Of 139 patients, 68 had complete samples and no additional neoadjuvant chemotherapy. Twenty-two were responders and 19 of those had sufficient tissue for whole-genome sequencing. We identified an additional 19 non-responders for a matched case-control analysis of 38 patients using a MAESTRO ctDNA assay tracking 319-1000 variants (median 1000 variants) to 114 plasma samples from 3 timepoints. Overall, ctDNA positivity was 100% at baseline, 79% at week 3 and 55% at week 12. Median tumor fraction (TFx) was 3.7 × 10-4 (range 7.9 × 10-7-4.9 × 10-1). TFx decreased 285-fold from baseline to week 3 in responders and 24-fold in non-responders. Week 12 ctDNA clearance correlated with RCB: clearance was observed in 10 of 11 patients with RCB 0, 3 of 8 with RCB 1, 4 of 15 with RCB 2 and 0 of 4 with RCB 3. Among six patients with known recurrence, five had persistent ctDNA at week 12. CONCLUSIONS: Neoadjuvant chemotherapy for TNBC reduced ctDNA TFx by 285-fold in responders and 24-fold in non-responders. In 58% (22/38) of patients, ctDNA TFx dropped below the detection level of a commercially available test, emphasizing the need for sensitive tests. Additional studies will determine whether ctDNA-guided approaches can improve outcomes.

mTOR-dependent loss of PON1 secretion and antiphospholipid autoantibody production underlie autoimmunity-mediated cirrhosis in transaldolase deficiency.

Transaldolase deficiency predisposes to chronic liver disease progressing from cirrhosis to hepatocellular carcinoma (HCC). Transition from cirrhosis to hepatocarcinogenesis depends on mitochondrial oxidative stress, as controlled by cytosolic aldose metabolism through the pentose phosphate pathway (PPP). Progression to HCC is critically dependent on NADPH depletion and polyol buildup by aldose reductase (AR), while this enzyme protects from carbon trapping in the PPP and growth restriction in TAL deficiency. Although AR inactivation blocked susceptibility to hepatocarcinogenesis, it enhanced growth restriction, carbon trapping in the non-oxidative branch of the PPP and failed to reverse the depletion of glucose 6-phosphate (G6P) and liver cirrhosis. Here, we show that inactivation of the TAL-AR axis results in metabolic stress characterized by reduced mitophagy, enhanced overall autophagy, activation of the mechanistic target of rapamycin (mTOR), diminished glycosylation and secretion of paraoxonase 1 (PON1), production of antiphospholipid autoantibodies (aPL), loss of CD161+ NK cells, and expansion of CD38+ Ito cells, which are responsive to treatment with rapamycin in vivo. The present study thus identifies glycosylation and secretion of PON1 and aPL production as mTOR-dependent regulatory checkpoints of autoimmunity underlying liver cirrhosis in TAL deficiency.

Clinical outcomes following surgical management of insertional Achilles tendinopathy using a double-row suture bridge technique with mean two-year follow-up.

BACKGROUND: The clinical outcomes following surgical management of insertional Achilles tendinopathy (IAT) vary depending on the surgical technique used to reattach the Achilles tendon following debridement. The aim of this study was to investigate the clinical outcomes of patients with IAT who underwent surgical management with a double-row suture bridge technique used to reattach the Achilles tendon. METHODS: A retrospective review of consecutive patients diagnosed with IAT, who underwent surgical management utilising a double-row suture bridge technique (Arthex Speedbridge), and a minimum of 3-month follow-up were included. The primary outcome was the Manchester-Oxford Foot Questionnaire (MOXFQ) Index score which is a patient reported outcome measure (PROM). Secondary outcomes included EuroQol EQ-5D-5L health-related quality of life PROM and complication rates. RESULTS: Between July 2013 and June 2020, 50 consecutive patients (23 male; 27 female) were included. The mean age (± standard deviation) was 52.3 ± 11.3 (range 29.0-84.3). Pre- and post-operative PROM data were available for all cases. The mean follow-up was 2.4 ± 1.9 years. The MOXFQ Index score improved from 48.5 to 12.4 (p < 0.01), EQ-5D-5L improved from 2.7 ± 0.46 to 1.2 ± 0.37 (p < 0.01), and EQ-VAS improved from 48.0 ± 18.4 to 84.1 ± 12.6 (p < 0.01). Four patients had complications which were of minimal clinical relevance and caused no deviation from routine recovery. There were no cases of tendon rupture. CONCLUSION: This study has demonstrated that surgical management of IAT is safe and effective with clinical improvement in both clinical and general health-related quality of life outcome PROMs. LEVEL OF EVIDENCE: IV.

GJB5 association with BRAF mutation and survival in cutaneous malignant melanoma.

BACKGROUND: Gap-junctional intercellular communication is crucial for epidermal cellular homeostasis. Inability to establish melanocyte-keratinocyte contact and loss of the intercellular junction's integrity may contribute to melanoma development. Connexins, laminins and desmocollins have been implicated in the control of melanoma growth, where their reduced expression has been reported in metastatic lesions. OBJECTIVES: The aim of this study was to investigate connexin 31·1 (GJB5) expression and identify any association with BRAF mutational status, prognosis of patients with melanoma and mitogen-activated protein kinase (MAPK) inhibitor (MAPKi) treatment. METHODS: GJB5 expression was measured at RNA and protein level in melanoma clinical samples and established cell lines treated (or not) with BRAF and MEK inhibitors (MEKi), as well as in cell lines which developed MAPKi resistance. Findings were further validated and confirmed by analysis of independent datasets. RESULTS: Our analysis reveals significant downregulation of GJB5 expression in metastatic melanoma lesions compared with primary ones and in BRAF-mutated vs. BRAF-wildtype (BRAFWT ) melanomas. Likewise, GJB5 expression is significantly lower in BRAFV600E compared with BRAFWT cell lines and increases on MAPKi treatment. MAPKi-resistant melanoma cells display a similar expression pattern compared with BRAFWT cells, with increased GJB5 expression associated with morphological changes. Enhancement of BRAFV600E expression in BRAFWT melanoma cells significantly upregulates miR-335-5p expression with consequent downregulation of GJB5, one of its targets. Furthermore, overexpression of miR-335-5p in two BRAFWT cell lines confirms specific GJB5 protein downregulation. Reverse transcriptase quantitative polymerase chain reaction analysis also revealed upregulation of miR-335 in BRAFV600E melanoma cells, which is significantly downregulated in cells resistant to MEKi. Our data were further validated using the TCGA_SKCM dataset, where BRAF mutations associate with increased miR-335 expression and inversely correlate with GJB5 expression. In clinical samples, GJB5 underexpression is also associated with patient overall worse survival, especially at early stages. CONCLUSIONS: We identified a significant association between metastases/BRAF mutation and low GJB5 expression in melanoma. Our results identify a novel mechanism of gap-junctional protein regulation, suggesting a prognostic role for GJB5 in cutaneous melanoma.

"Do-not-touch" lesions of bone revisited.

Incidental bone lesions are encountered frequently in day-to-day practice. Many of these lesions are indeterminate requiring referral to specialist centres for further characterisation with or without biopsy; however, as biopsy has its own drawbacks, not all lesions can be subjected to biopsy. The primary role of a radiologist in these situations is to characterise these lesions based on their imaging appearances into aggressive lesions requiring biopsy and non-aggressive lesions that do not require a biopsy. The term "do-not-touch lesion" is used to describe a lesion with typical radiographic appearances that can be characterised based on radiographic appearances alone without needing a biopsy. With recent advances in imaging, many incidental lesions can be characterised into do-not-touch lesions based on their imaging appearances alone using a single imaging technique or using a combination of imaging techniques and, less frequently, with the additional help of serological investigations, without the need for biopsy. Hence, the definition of do-not-touch lesions of bone needs a revisit. In this article, we attempt to redefine do-not-touch lesions of bone and propose an imaging-based classification for characterisation of these lesions.

Absence of clinical benefit of FDG PET-CT in staging T1 part-solid lung adenocarcinoma.

AIM: To assess the rates of nodal and metastatic disease and change in management when staging part-solid T1 lung adenocarcinomas using integrated 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography (PET)-computed tomography (CT) in a UK population. MATERIALS AND METHODS: This was a retrospective review of PET-CT examinations performed to stage radiologically suspected T1 part-solid lung adenocarcinoma (n=58) from two different centres. Rates of detection of nodal and metastatic disease, change in management, and final patient outcome were recorded. RESULTS: PET-CT changed the stage in one patient from N0 to N1. It did not change final management in any patient. CONCLUSIONS: In this UK population, PET-CT had minimal additional diagnostic benefit in staging patients with T1 part-solid lung adenocarcinoma. Especially given its cost, the inclusion of PET-CT for this indication in guidelines should be reviewed.

Deeper may not be better: relationship between catheter dysfunction and location of the catheter tip in right-sided tunnelled haemodialysis catheters.

AIM: To examine the relationship between catheter tip location and catheter dysfunction in the context of tunnelled central venous catheters (CVCs) for haemodialysis. MATERIALS AND METHODS: This was a retrospective study of 993 haemodialysis patients who underwent insertion of tunnelled CVCs of step-tip design via the right internal jugular vein (IJV). Based on intra-procedural radiographs, the catheter tip was characterised as being in the superior vena cava (SVC), cavo-atrial junction (CAJ), or deep right atrium (DRA). Patients were tracked for 90 days post-procedure for complications resulting in catheter replacement, and these were compared between cohorts. Statistical analysis was performed with Pearson's chi-square and Fisher's exact tests for categorical variables and two-sample t-test and one-way analysis of variance (ANOVA) for continuous variables. RESULTS: Ninety-five patients (9.6%) experienced catheter dysfunction necessitating replacement within 90 days of insertion. Tip location in SVC was associated with lower occurrence of catheter dysfunction (1.9%) as compared with the CAJ (8%) and DRA (11%; p=0.049). Catheter replacement due to other complications (catheter-associated bacteraemia, cuff dislodgement, exit-site infection, external catheter damage) showed no statistically significant relation to location of the CVC tip. CONCLUSION: When utilising tunnelled CVCs with a step-tip design inserted via the right IJV, location of the catheter tip in the SVC is associated with reduced occurrence of catheter dysfunction as compared to either the CAJ or DRA.

Image-based automated Psoriasis Area Severity Index scoring by Convolutional Neural Networks.

BACKGROUND: The Psoriasis Area and Severity Index (PASI) score is commonly used in clinical practice and research to monitor disease severity and determine treatment efficacy. Automating the PASI score with deep learning algorithms, like Convolutional Neural Networks (CNNs), could enable objective and efficient PASI scoring. OBJECTIVES: To assess the performance of image-based automated PASI scoring in anatomical regions by CNNs and compare the performance of CNNs to image-based scoring by physicians. METHODS: Imaging series were matched to PASI subscores determined in real life by the treating physician. CNNs were trained using standardized imaging series of 576 trunk, 614 arm and 541 leg regions. CNNs were separately trained for each PASI subscore (erythema, desquamation, induration and area) in each anatomical region (trunk, arms and legs). The head region was excluded for anonymity. Additionally, PASI-trained physicians retrospectively determined image-based subscores on the test set images of the trunk. Agreement with the real-life scores was determined with the intraclass correlation coefficient (ICC) and compared between the CNNs and physicians. RESULTS: Intraclass correlation coefficients between the CNN and real-life scores of the trunk region were 0.616, 0.580, 0.580 and 0.793 for erythema, desquamation, induration and area, respectively, with similar results for the arms and legs region. PASI-trained physicians (N = 5) were in moderate-good agreement (ICCs 0.706-0.793) with each other for image-based PASI scoring of the trunk region. ICCs between the CNN and real-life scores were slightly higher for erythema (0.616 vs. 0.558), induration (0.580 vs. 0.573) and area scoring (0.793 vs. 0.694) than image-based scoring by physicians. Physicians slightly outperformed the CNN on desquamation scoring (0.580 vs. 0.589). CONCLUSIONS: Convolutional Neural Networks have the potential to automatically and objectively perform image-based PASI scoring at an anatomical region level. For erythema, desquamation and induration scoring, CNNs performed similar to physicians, while for area scoring CNNs outperformed physicians on image-based PASI scoring.

Foot care knowledge and self-care practices among diabetic patients in Penang: A primary care study.

INTRODUCTION: In Malaysia, the prevalence of diabetes mellitus has been increasing annually, currently affecting 18.3% of the population. Diabetic foot ulcer, a common complication of diabetes, is associated with high morbidity and mortality, consequently increasing health care expenditure. A previous study showed that foot care knowledge and foot self-care practices help to reduce the development of ulcers.1,2 This study aims to identify the level of foot care knowledge and self-care practices among diabetic patients in the primary care setting. OBJECTIVE: This study was to determine the level of foot care knowledge and foot self-care practices among diabetic patients in the primary care setting in Penang Island and its determinants and the correlation between level of foot care knowledge and self-care practices among diabetic patients. MATERIAL AND METHODS: A cross sectional study was performed on 311 diabetic patients who were registered to two government health clinics in Penang. Information regarding respondents' demographic status, foot care knowledge, and foot self-care practices were gathered using a self-administered questionnaire. Data were analysed using the Statistical Package for the Social Sciences (SPSS) 22. The Mann-Whitney U test and Kruskal-Wallis test were applied to the analysis. Multiple linear regression was performed to identify the determinants. Correlation between knowledge and self-care practice was determined using the linear regression model. RESULTS: One hundred and sixty-five (53.1%) respondents achieved good knowledge scores and 196 respondents (63%) achieved good self-care practice scores. The median age of respondents was 61 years, who were mostly females (56.6%), Malays (41.2%), and unemployed (48.6%). Median HbA1c level was 7.5%, and 42.8% of respondents had diabetes for 5 to 10 years. Lowest scores for knowledge and self-care practices were observed in foot skin care questions. Formal foot care education was found to be a significant predictor of foot care knowledge (p<0.05, 95% CI -1.102, -0.098). Foot care knowledge was significantly and positively correlated with foot self-care practices (p<0.001, 95% CI 0.548, 0.727). CONCLUSION: Foot care knowledge has significant positive correlation with foot self-care practices. Empowering diabetic patients with foot care knowledge may lead to significantly better foot self-care practices.

IgE blockade with omalizumab reduces pruritus related to immune checkpoint inhibitors and anti-HER2 therapies.

BACKGROUND: Immunoglobulin E (IgE) blockade with omalizumab has demonstrated clinical benefit in pruritus-associated dermatoses (e.g. atopic dermatitis, bullous pemphigoid, urticaria). In oncology, pruritus-associated cutaneous adverse events (paCAEs) are frequent with immune checkpoint inhibitors (CPIs) and targeted anti-human epidermal growth factor receptor 2 (HER2) therapies. Thus, we sought to evaluate the efficacy and safety of IgE blockade with omalizumab in cancer patients with refractory paCAEs related to CPIs and anti-HER2 agents. PATIENTS AND METHODS: Patients included in this multicenter retrospective analysis received monthly subcutaneous injections of omalizumab for CPI or anti-HER2 therapy-related grade 2/3 pruritus that was refractory to topical corticosteroids plus at least one additional systemic intervention. To assess clinical response to omalizumab, we used the Common Terminology Criteria for Adverse Events version 5.0. The primary endpoint was defined as reduction in the severity of paCAEs to grade 1/0. RESULTS: A total of 34 patients (50% female, median age 67.5 years) received omalizumab for cancer therapy-related paCAEs (71% CPIs; 29% anti-HER2). All had solid tumors (29% breast, 29% genitourinary, 15% lung, 26% other), and most (n = 18, 64%) presented with an urticarial phenotype. In total 28 of 34 (82%) patients responded to omalizumab. The proportion of patients receiving oral corticosteroids as supportive treatment for management of paCAEs decreased with IgE blockade, from 50% to 9% (P < 0.001). Ten of 32 (31%) patients had interruption of oncologic therapy due to skin toxicity; four of six (67%) were successfully rechallenged following omalizumab. There were no reports of anaphylaxis or hypersensitivity reactions related to omalizumab. CONCLUSIONS: IgE blockade with omalizumab demonstrated clinical efficacy and was well tolerated in cancer patients with pruritus related to CPIs and anti-HER2 therapies.

How has COVID-19 affected the treatment of osteoporosis? An IOF-NOF-ESCEO global survey.

The effects of COVID-19 have the potential to impact on the management of chronic diseases including osteoporosis. A global survey has demonstrated that these impacts include an increase in telemedicine consultations, delays in DXA scanning, interruptions in the supply of medications and reductions in parenteral medication delivery. INTRODUCTION: The COVID-19 pandemic has had profound effects on the health of the global population both directly, via the sequelae of the infection, and indirectly, including the relative neglect of chronic disease management. Together the International Osteoporosis Foundation and National Osteoporosis Foundation sought to ascertain the impact on osteoporosis management. METHODS: Questionnaires were electronically circulated to a sample of members of both learned bodies and included information regarding the location and specialty of respondents, current extent of face to face consultations, alterations in osteoporosis risk assessment, telemedicine experience, alterations to medication ascertainment and delivery and electronic health record (EHR) utilisation. Responses were collected, quantitative data analysed, and qualitative data assessed for recurring themes. RESULTS: Responses were received from 209 healthcare workers from 53 countries, including 28% from Europe, 24% from North America, 19% from the Asia Pacific region, 17% from the Middle East and 12% from Latin America. Most respondents were physicians (85%) with physician assistants, physical therapists and nurses/nurse practitioners represented in the sample. The main three specialties represented included rheumatology (40%), endocrinology (22%) and orthopaedics (15%). In terms of the type of patient contact, 33% of respondents conducted telephone consultations and 21% video consultations. Bone mineral density assessment by dual-energy X-ray absorptiometry (DXA) usage was affected with only 29% able to obtain a scan as recommended. The majority of clinicians (60%) had systems in place to identify patients receiving parenteral medication, and 43% of clinicians reported difficulty in arranging appropriate osteoporosis medications during the COVID-19 crisis. CONCLUSIONS: To conclude through surveying a global sample of osteoporosis healthcare professionals, we have observed an increase in telemedicine consultations, delays in DXA scanning, interrupted supply of medications and reductions in parenteral medication delivery.

From benchtop to clinic: a translational analysis of the immune response to submicron topography and its relevance to bone healing.

Proper regulation of the innate immune response to bone biomaterials after implantation is pivotal for successful bone healing. Pro-inflammatory M1 and anti-inflammatory M2 macrophages are known to have an important role in regulating the healing response to biomaterials. Materials with defined structural and topographical features have recently been found to favourably modulate the innate immune response, leading to improved healing outcomes. Calcium phosphate bone grafts with submicron-sized needle-shaped surface features have been shown to trigger a pro-healing response through upregulation of M2 polarised macrophages, leading to accelerated and enhanced bone regeneration. The present review describes the recent research on these and other materials, all the way from benchtop to the clinic, including in vitro and in vivo fundamental studies, evaluation in clinically relevant spinal fusion models and clinical validation in a case series of 77 patients with posterolateral and/or interbody fusion in the lumbar and cervical spine. This research demonstrates the feasibility of enhancing biomaterial-directed bone formation by modulating the innate immune response through topographic surface features.

Quality of life with pharmacological treatment in patients with benign prostatic enlargement: results from the Evolution European Prospective Multicenter Multi-National Registry Study.

BACKGROUND: Lower urinary tract symptoms due to benign prostate enlargement (LUTS/BPE) can lead to significant disturbances to health-related quality of life (HRQoL) and psychological well-being. The aim of this study was to evaluate the effect of pharmacological treatment of LUTS/BPE on disease specific and generic QOL measures. METHODS: Evolution was a European prospective, multicenter multi-national, observational registry collecting real-life clinical data over 2 years on the management of LUTS/BPE in primary and secondary care. This study investigated disease-specific QOL using questionnaires such as IPSS Q8, BPH Impact Index (BII) and generic QOL using questionnaires like EuroQOL Five Dimension (EQ5D) which encompassed EQ5D VAS and EQ5D health index. RESULTS: The registry enrolled 1838 BPE patients and 1246 patients were evaluable at the end of 24 months. Nearly 70% of patients in the study were previously treated with medical therapy and 17% of these had already discontinued medical treatment previously for various reasons with lack of efficacy being the most common. The mean time since diagnosis of LUTS in the previously treated group was 4.7 years (0-26 years). Medical management produced statistically significant improvement in QOL (disease specific and generic) in previously untreated patients and an insignificant change in generic QOL in previously treated patients. CONCLUSIONS: After 5-years from the onset of symptoms, LUTS/BPE patients previously treated with medication had significantly impaired QOL in patients in a manner comparable to other chronic diseases. Earlier intervention with minimally invasive surgical techniques (MIT) should be considered in LUTS/BPE patients that do not show a significant improvement in QOL with medical therapy.

Contemporary use of phytotherapy in patients with lower urinary tract symptoms due to benign prostatic hyperplasia: results from the EVOLUTION European registry.

BACKGROUND: To use the European Association of Urology Research Foundation (EAURF) registry data to determine the proportion of contemporary Lower Urinary Tract Symptoms associated with Benign Prostatic Enlargement (LUTS/BPE) patients prescribed phytotherapy, and to determine their subjective quality of life and clinical progression responses. METHODS: This was a prospective multicenter multinational observational registry study, conducted over 2 years. Men ≥ 50 years seeking LUTS/BPE were divided at baseline into two cohorts, presently/recently untreated patients (PUP) commencing pharmacotherapy at baseline and presently/recently treated patients (c-PTP) continuing previously received pharmacotherapy, with 24-month follow-up (FU). RESULTS: Overall, 2175 patients were enrolled with 1838 analyzed. Of the PUP cohort (n = 575), 92 (16%) received phytotherapy and 65 (71%, n = 65/92) completed 24-month FU, with France prescribing 34% (n = 30/89) the highest proportion of phytotherapy among all LUTS/BPE medications. In the c-PTP group (n = 1263), only 69 (5%) patients were using phytotherapy, falling to n = 35/69 (51%) at 24-month FU (highest in France 20% (n = 43/210)). Though defined disease progression occurred in ≤ 20%, with only 1% proceeding to surgical intervention, in both groups, clinically meaningful improvement was lower and symptom persistence was higher in PUP but similar in the treated (c-PTP) patients on phytotherapy compared to the other LUTS/BPE medication. CONCLUSION: Low heterogeneous prescribing rates for phytotherapy were reported in both PUP and c-PTP cohorts over the 24-month FU. Although phytotherapy led to subjective improvements, healthcare practitioners should prescribe them with caution until higher quality evidence and guideline recommendations supporting its use are available.

Association of haemoglobin levels in the first trimester and at 26-30 weeks with fetal and neonatal outcomes: a secondary analysis of the Global Network for Women's and Children's Health's ASPIRIN Trial.

OBJECTIVE: Limited data are available from low- and middle-income countries (LMICs) on the relationship of haemoglobin levels to adverse outcomes at different times during pregnancy. We evaluated the association of haemoglobin levels in nulliparous women at two times in pregnancy with pregnancy outcomes. DESIGN: ASPIRIN Trial data were used to study the association between haemoglobin levels measured at 6+0 -13+6  weeks and 26+0 -30+0  weeks of gestation with fetal and neonatal outcomes. SETTING: Obstetric care facilities in Pakistan, India, Kenya, Zambia, The Democratic Republic of the Congo and Guatemala. POPULATION: A total of 11 976 pregnant women. METHODS: Generalised linear models were used to obtain adjusted relative risks and 95% CI for adverse outcomes. MAIN OUTCOME MEASURES: Preterm birth, stillbirth, neonatal death, small for gestational age (SGA) and birthweight <2500 g. RESULTS: The mean haemoglobin levels at 6+0 -13+6  weeks and at 26-30 weeks of gestation were 116 g/l (SD 17) and 107 g/l (SD 15), respectively. In general, pregnancy outcomes were better with increasing haemoglobin. At 6+0 -13+6  weeks of gestation, stillbirth, SGA and birthweight <2500 g, were significantly associated with haemoglobin of 70-89 g/l compared with haemoglobin of 110-129 g/l The relationships of adverse pregnancy outcomes with various haemoglobin levels were more marked at 26-30 weeks of gestation. CONCLUSIONS: Both lower and some higher haemoglobin concentrations are associated with adverse fetal and neonatal outcomes at 6+0 -13+6  weeks and at 26-30 weeks of gestation, although the relationship with low haemoglobin levels appears more consistent and generally stronger. TWEETABLE ABSTRACT: Both lower and some higher haemoglobin concentrations were associated with adverse fetal and neonatal outcomes at 6-13 weeks and 26-30 weeks of gestation.

Comprehensive Analysis of Adverse Events Associated with Gastric Peroral Endoscopic Myotomy: An International Multicenter Study.

BACKGROUND: Gastric peroral endoscopic myotomy (G-POEM) has emerged as an effective management approach for patients with refractory gastroparesis. This study aims to comprehensively study the safety of G-POEM and describe the predictive factors of adverse events (AEs) occurrence. METHODS: This study is a retrospective study involving 13 tertiary care centers (7 USA, 1 South America, 4 Europe, and 1 Asia). Patients who underwent G-POEM for refractory gastroparesis were included. Cases were identified by the occurrence of AEs. For each case, two controls were randomly selected and matched for age (± 10 years), gender, and etiology of gastroparesis. RESULTS: A total of 216 patients underwent G-POEM for gastroparesis. Overall, 31 (14%) AEs were encountered [mild 24 (77%), moderate 5 (16%), and severe 2 (6%)] during the duration of the study. The most common AE was abdominal pain (n = 16), followed by mucosotomy (n = 5) and capnoperitoneum (n = 4), and AEs were most commonly identified within the first 48-h post-procedure 18 (58%). The risk of adverse event occurrence was significantly higher for endoscopists with experience of < 20 G-POEM procedures (OR 3.03 [1.03-8.94], p < 0.05). CONCLUSION: G-POEM seems to be a safe intervention for refractory gastroparesis. AEs are most commonly mild and managed conservatively. Longitudinal mucosal incision, use of hook knife, use of clips for mucosal closure and endoscopist's experience with > 20 G-POEM procedures is significantly associated with decreased incidence of AEs.

Clinical phenotypes and therapeutic responses in cutaneous-predominant sarcoidosis: 6-year experience in a tertiary referral service.

BACKGROUND: There is a limited evidence base for the treatment of cutaneous sarcoidosis. OBJECTIVE: To describe treatment modalities and responses in patients with predominantly cutaneous sarcoidosis, in addition to clinical characteristics and prevalence of systemic disease. METHODS: Data were prospectively collected over a 6-year period. The Cutaneous Sarcoidosis Activity and Morphology Index was used to assess treatment effectiveness. RESULTS: In total, 47 patients with biopsy-confirmed cutaneous sarcoidosis were identified. Morphologically, the most common lesions were papules (49%) and plaques (42.6%). The most commonly affected sites were the head and neck (79%); 89.4% had systemic as well as cutaneous disease; 77% received systemic corticosteroid therapy, while 87% required further steroid-sparing treatment; 40% achieved clinical remission with hydroxychloroquine (HCQ) and 88% achieved clinical remission with methotrexate (MTX). OR of achieving remission on MTX compared with HCQ was 9.8 (95% CI 2.4-40.4, P = 0.001). MTX was superior to both azathioprine (AZA) (OR = 22; 95% CI 1.7-285.9; P = 0.02) and mycophenolate mofetil (MMF) (OR = 22; 95% CI 1.7-285.9; P = 0.02) in achieving remission. CONCLUSION: HCQ is effective and well-tolerated. MTX was associated with significantly increased probability of achieving clinical remission compared with AZA and MMF.

Modified Broström repair with suture tape augmentation for lateral ankle instability: A systematic review.

BACKGROUND: There is increasing interest in augmentation of modified Broström repairs for lateral ankle instability with a prosthetic reconstruction using suture tape internal bracing. The aim of this study was to investigate if suture tape augmentation resulted in improved clinical and radiological outcomes compared to a standard modified Broström repair alone. METHODS: A systematic review following PRISMA guidelines was undertaken. All clinical studies published in Medline, Embase, Pubmed and the Cochrane Library Database from inception until January 2020 reporting on the use of suture tape augmentation to a modified Broström repair for lateral ankle instability. RESULTS: 78 studies were identified of which 10 (assessing 333 patients) met the criteria for inclusion. Mean follow up was 24.8 months (range 6-52 months). All studies showed a statistically significant improvement across multiple clinical outcome measures post-surgery in both suture tape augmentation and modified Broström groups, however there were no statistically significant inter-group differences. Pooled results suggested there may be a reduction in recurrence of instability with suture tape augmentation when compared to modified Broström repair alone (p < 0.05). Overall quality of evidence was moderate to poor with limited data to support use of suture tape augmentation. CONCLUSION: Clinical and radiographic outcomes using a suture tape internal bracing for lateral ankle instability are excellent, and are equivalent to standard treatment across multiple clinical and radiographic assessment measures. There is minimal evidence to suggest functional outcomes are better, or recurrence rates are lower than modified Broström repair alone. PROSPERO REGISTRY: CRD42020169876. LEVEL OF EVIDENCE: II.

Management of cardiac disease in cancer patients throughout oncological treatment: ESMO consensus recommendations.

Cancer and cardiovascular (CV) disease are the most prevalent diseases in the developed world. Evidence increasingly shows that these conditions are interlinked through common risk factors, coincident in an ageing population, and are connected biologically through some deleterious effects of anticancer treatment on CV health. Anticancer therapies can cause a wide spectrum of short- and long-term cardiotoxic effects. An explosion of novel cancer therapies has revolutionised this field and dramatically altered cancer prognosis. Nevertheless, these new therapies have introduced unexpected CV complications beyond heart failure. Common CV toxicities related to cancer therapy are defined, along with suggested strategies for prevention, detection and treatment. This ESMO consensus article proposes to define CV toxicities related to cancer or its therapies and provide guidance regarding prevention, screening, monitoring and treatment of CV toxicity. The majority of anticancer therapies are associated with some CV toxicity, ranging from asymptomatic and transient to more clinically significant and long-lasting cardiac events. It is critical however, that concerns about potential CV damage resulting from anticancer therapies should be weighed against the potential benefits of cancer therapy, including benefits in overall survival. CV disease in patients with cancer is complex and treatment needs to be individualised. The scope of cardio-oncology is wide and includes prevention, detection, monitoring and treatment of CV toxicity related to cancer therapy, and also ensuring the safe development of future novel cancer treatments that minimise the impact on CV health. It is anticipated that the management strategies discussed herein will be suitable for the majority of patients. Nonetheless, the clinical judgment of physicians remains extremely important; hence, when using these best clinical practices to inform treatment options and decisions, practitioners should also consider the individual circumstances of their patients on a case-by-case basis.
