Association of apolipoprotein E4 to the number of cerebral microbleeds in patients recovered from COVID-19

Background: COVID-19 has been associated with cerebral microbleeds (CMB). Previously, an association of ApoE4 with COVID-19 severity and CMBs in autopsy was found. In this study, we investigated if carrying the Apoe4 allele relates to the number of CMBs in magnetic resonance imaging (MRI) in patients recovered from COVID-19. Material(s) and Method(s): Adult patients recovered from COVID-19 and a control group without a history of COVID-19 was recruited. Exclusion criteria were major neurologic disease, developmental disability or pregnancy. The participants underwent brain MRI 6 months after infection, and a blinded neuroradiologist analyzed the findings. ApoE was genotyped using a microarray. Statistical analysis was performed using the statistical software R. A negative binomial model was chosen based on the distribution of CMBs. Result(s): Of the 216 subjects that underwent MRI, 168 consented to genetic testing, additionally 2 patients were excluded due to extensive CMBs and 1 due to diffuse axonal injury. We included 113 COVID-19 patients (49 ICU-treated, 29 ward-treated and 35 home-isolated) and 52 controls. The most prevalent comorbidities were hypertension, asthma and diabetes. CMBs was found in 47 subjects, with the number of CMBs ranging from 0 to 26. The ApoeE4 allele was carried by 37%, equally distributed among the groups. After adjustment, age (aRR = 1.06, p = 0.007) and COVID-19 (aRR = 2.59, p = 0.038) were independently associated with CMBs. The ApoE4 allele (aRR = 2.16, p = 0.07, CI = 0.94-5.10) was not significant. Conclusion(s): Age and previous COVID-19, but not possession of the ApoeE4 allele, were independently associated with the number of CMBs.

Dynamic MRI in a COVID-19 patient: a case series

Extensive spread of the coronavirus disease (COVID-19) prompted an investigation of its diagnostic features. Acute viral pneumonia associated with COVID-19 has been described in detail using CT, radiography, and MRI. There is no data in the literature on the descriptive picture observed with dynamic MRI. Considering a comprehensive diagnostic approach, radiologists should know how to correctly recognize and interpret COVID-19 on MRI. This case series demonstrated the ability of dynamic MRI to detect the cloudy sky sign and distinguish it from consolidation in COVID-19 patients, thus presumably distinguishing between early or mild changes and a progressive clinical course. These changes in dynamic lung images on MRI can be recorded depending on the phase of the respiratory cycle. Thus, MRI, as a radiation-free tool that can be used to examine a patient with acute viral pneumonia COVID-19, can be useful in cases where access to computed tomography is limited and dynamic morphofunctional imaging is required. © Eco-Vector, 2023.

AVASCULAR NECROSIS OF THE FEMORAL HEAD – NOT TO BE OVERLOOKED SEQUELA AFTER COVID 19 INFECTION

BackgroundCOVID 19 infection could lead to different sequelae in survivors, known as post-COVID or long COVID 19 syndromes. Some of them are thought to be due to the thrombophylic changes observed in COVID 19 infection, but some are thought to be caused by the administrated (especially high dose) corticosteroid treatment. Avascular necrosis of the femoral head (AVNFH) is a multifactorial disease which leads to compromised vascular supply, ischemia and finally necrosis of the femoral head. As corticosteroids usage and thrombophylic states are among the main known risk factors for the development AVNFH [1], it could be presumed that the frequency of this disease will increase with the COVID 19 pandemic. The exact corticosteroid dose needed for the development of AVNFH is not clear, but it has been stated that a higher daily dose and a larger total cumulative dose increase substantially the risk for the development of osteonecrosis [2].ObjectivesTo describe in detail the characteristics of AVNFH diagnosed in patients after COVID 19 infection.MethodsThe study was done in a tertiary university rheumatological clinic. Data was extracted from the records of patients who have been referred to the clinic because of hip pain between June and December 2022. Inclusion criteria were: - a new onset of uni-or bilateral hip pain that started after a documented COVID 19 infection;and an MRI scan of the hip joints showing osteonecrosis of one or both femoral heads. Exclusion criteria were the presence of hip pain prior to the COVID 19 infection, anamnesis of traumatic injuries of the hips or pelvis, personal history of hypercoagulable states.ResultsNine patients (4 women and 5 men) with an average age 59.1 years (range 38-72) were included in the study. Four patients had been diagnosed with bilateral and five – with unilateral AVNFH, thus 13 hip joints were analysed in total (8 left and 5 right sided). The mean time lap between the COVID 19 infection and the start of the hip pain was 26.2 weeks (range 10-48 weeks). All patients had limited and painful movement in their symptomatic hip(s), especially internal rotation and four of the patients had also elevated CRP levels (mean 11.7 mg/L). The stage of the AVNFH was evaluated according to the Ficat-Arlet classification (0-IV stage). In four hips the AVNFH was stage I, five hips were classified as stage II and the remaining four joints - as stage III. All symptomatic hip joints exhibited effusion/synovitis on both ultrasound examination and the corresponding MRI scan. It should be noted that the presence of hip effusion was found to be related with a worse prognosis in AVNFH [1]. In three patients the amount of the effusion required arthrocentesis and fluid aspiration. The analysis of the joint fluid was consistent with a degenerative disease (i.e., low WBC count with predominant lymphocytes and no crystals). All patients included in our study had received corticosteroids during their COVID19 infection, while 6 of the patients had also been hospitalized due to more severe disease. According to the patients' documentation, the mean cumulative dose of the received corticosteroids was 936.2 mg prednisolone equivalent per patient (range 187-2272 mg).ConclusionAVNFH must not be overlooked in a new onset hip pain after COVID 19 infection. Our results show that corticosteroids administrated during the infection and the presence of hip joint effusion on ultrasound are especially suggestive for the development of osteonecrosis, as they were registered in all of our patients. The presence of these two factors necessitates patient referral for an MRI scan of the hips, in order that AVNFH be detected timely.References[1]Petek D, Hannouche D, Suva D.

Pleurisy and pericarditis as a cause of atypical chest pain in patients with in early post-COVID-19 period.

During the pandemic COVID-19, there has been an increase in the number of patients with non-anginal chest pain at cardiologist appointments. Objective. To assess the incidence of signs of pleurisy and pericarditis after COVID-19 in non-comorbid patients with atypical chest pain and describe their characteristics according to echocardiography and magnetic resonance imaging. Materials and methods. From February 2021 to January 2022, 200 outpatients were prospectively enrolled in the study, all of them suffered from a discomfort in the heart region for the first time after SARS-CoV-2 infection. Inclusion criteria: 18-50 years old, 5-12 weeks after SARS-CoV-2 infection, non-anginal chest pain. Exclusion criteria: pneumonia or signs of pulmonary thromboembolism, coronary heart disease, congestive heart failure or kidney disease, clinical or laboratory signs of myocarditis, oncopathology, radiation or chemotherapy of the chest in past medical history. A survey was conducted (yes/no) for the presence of general malaise, quality of life deterioration, hyperthermia, cough. Ultrasound examination of the pericardium and pleura to detect effusion or post-inflammatory changes was performed in accordance with the recommendations. Magnetic resonance imaging was performed if ultrasound imaging was poor or there was no evidence of pericardial or pleural involvement in patients with typical symptoms. Results. 82 women and 118 men were included. Median of age 39 [28-46] years old. Pericarditis was diagnosed in 152 (76%) patients, including effusive pericarditis in 119 (78%), myocarditis in 6 (3%) and myopericarditis in 49 (25%) patients, pleurisy was detected in 22 (11%) patients, exudative pleurisy - in 11 (5.5%) patients with a predominant unilateral lesion of the mediastinal-diaphragmatic region adjacent to the heart. Hyperthermia was recorded in 2.5% of cases, general malaise - in 60% and a decrease in the quality of life - in 84%. Conclusion. Serositis as a cause of atypical chest pain among young non-comorbid patients in early postCOVID was identified in 87% of patients. In the coming years, it is probably worthwhile to perform ultrasound of the pericardium and pleura in all patients with chest pain.Copyright © 2022 Infectious Diseases: News, Opinions, Training.

Cerebral microbleeds and Fazekas scale in brain magnetic resonance imaging after critical COVID-19: A prospective cohort study

Background: We aimed to report long-term brain magnetic resonance imaging (MRI) findings in survivors of ICU-treated COVID-19 compared to other groups. Material(s) and Method(s): In this prospective cohort study 70 ICU-treated, 46 ward-treated and 46 home-isolated patients, diagnosed with COVID-19 in 2020, underwent brain MRI 6 months after the acute phase to determine the presence of cerebral microbleeds (CMB) and Fazekas scale. Result(s): CMBs existed in 27 (38.6%) ICU-treated, 13 (28.3%) ward-treated, 8 (17.4%) home-isolated COVID-19 patients, and in 12 (22.6%) non-COVID controls (Figure 1). The number of CMBs in COVID-19 patients and controls was median 2 (IQR 1-4) and 1 (IQR 1-2), respectively. Patients with CMBs differed from those without, regarding age (median 62 vs. 52 years, p < 0.001), history of arterial hypertension (50% vs. 31%, p = 0.03), need of ICU (56% vs. 38%, p = 0.03) and ventilator treatment (42% vs. 22%, p = 0.01), length of hospital stay (median 21 vs. 12 days, p < 0.001), and supplementary oxygen therapy (median 18 vs. 10 days, p = 0.008), respectively. Within the ICU group, patients with and without CMBs differed regarding the duration of ICU stay (median 17 vs. 9 days, p = 0.006), and mechanical ventilation (median 14 vs. 6 days, p = 0.002). In multivariable analysis, only age was associated with CMBs (OR 1.06, 95% CI 1.02-1.09). The majority of subjects in all groups had Fazekas scale one for white matter hyperintensities (Figure 1). Conclusion(s): Although the severity of respiratory failure and history of arterial hypertension were associated with the presence of CMBs, only age was an independent predictor of CMBs.

Role of telemedicine in anesthesia: Are we ready yet?

Telemedicine is a modality which utilizes technology to provide and support health care across large distances. It has redefined the practices of medicine in many specialties and continues to be a boon for clinicians on many frontiers. Its role in the branch of anesthesia remains largely unexplored but has shown to be beneficial in all the three phases: pre-operative, intra-operative, and post-operative. Now time has come that anesthesiologists across the globe reassess their strategies and utilize the telemedicine facilities in the field of anesthesia.Copyright © 2021 EDP Sciences.

The Impact of Covid19 Pandemic on Transfusion Dependent -Thalassemia Management: Experience of a Single Pediatric Treatment Center

Background: Health care systems have been facing COVID19 pandemic around the world for almost two years. Transfusion dependent (TDT) beta-thalassemia patients represent a vulnerable group,totally dependent upon hospital-based services. Aim(s): Aim of the present study was to evaluate the impact of COVID19 pandemic on management of TDT patients in a single pediatric treatment center in Northern Greece. Method(s): Patient records were reviewed in order to assess changes in management before and during the 24-month pandemic in Greece (03/01/2018-29/02/2020 and 03/01/2020 -28/02/2022, respectively) in terms of transfusion volume and transfusion frequency, mean value of pretransfusional hemoglobin, as well as laboratory parameters reflecting iron overload (ferritin levels, liver and heart MRI). Result(s): The study included 28 patients, 19 male (67.8%) and 9 female (32.2%), with an age range of 8 to 21 years. Mean number of hospital visits for transfusion was 19.97 +/- 3,52/ year prior to the pandemic and 22.38 +/- 4.35/year during the pandemic (p: 0.003). Average transfusion volume was 176.18ml +/- 38.32/kg/year kappaalphai 178.67 +/- 37.64ml/kg/year, respectively (p: 0.54). With regards to hemoglobin level, mean value was 9.56 +/- 0.42g/dl prior to the pandemic and 9.45 +/- 0.48gr/dl during the pandemic period. As to iron overload, mean ferritin level was 1362.05 +/- 517.56 ng/mL prior to the pandemic and 1021.27 +/- 508.92 ng/mL during the latter time period (p:0.016). Out of 28 enrolled patients, 26 underwent heart and liver MRI before pandemic and 23 during the pandemic period. Mean LIC values were 6.84 +/- 7.37 mg/gdw and 6.43 +/- 6.46 mg/gdw (p: 0.97) before and during the pandemic, respectively (p:0.97). Myocardial MRI values were within normal limits both before and during the pandemic. Summary-Conclusion: Covid19 pandemic did not seem to negatively affect the primary goal of transfusion therapy (pretransfusion Hb), even if an increased number of visits was required in order to transfuse the same blood volume - due to limited availability of blood units per visit. Of interest, pandemic conditions appeared to favor patient adherence to chelation therapy.

Radiological findings of mucormycosis rhinosinusitis among Indian COVID-19 patients during the pandemic second wave

Background: Sinonasal mucormycosis is a quickly progressing and lethal fungal disease which showed an increased incidence in COVID-19 patients in the Indian population during the second wave of the pandemic. The objective of this study was to study the various sinus areas affected and the imaging findings of the disease. Method(s): The imaging records of patients with sinonasal mucormycosis during the second wave of the COVID-19 pandemic were reviewed and analysed for whom computed tomography (CT) and/or magnetic resonance imaging (MRI) images had been performed. Result(s): Of the 65 patients, 6.1% had single sinus involvement, and 93.9% had multiple sinus involvement, and out of latter, 91.8% had bilateral sinuses affected by the disease process. A total of 49.2% patients with sinus involvement had erosions of the sinus walls. A total of 35.4% patients had only sinonasal mucormycosis, 38.5% patients had rhino-orbital mucormycosis, 4.6% patients had rhino-cerebral mucormycosis and 16.9% patients had rhino-orbitocerebral mucormycosis. The pterygopalatine fossa was affected in 26.2% patients. A total of 9.2% patients had cavernous sinus thrombosis. A total of 12% of the cases had infarction in the cerebral hemispheres. Conclusion(s): In a setting of sinonasal mucormycosis, especially in the immuno-compromised and with those infected with COVID-19, cross-sectional imaging can assess the presence and extent of the disease and helps plan its medical and surgical management.Copyright © 2023, The Author(s).

Towards Lifting the Trade-off between Accuracy and Adversarial Robustness of Deep Neural Networks with Application on COVID 19 CT Image Classification and Medical Image Segmentation

Deep neural networks (DNNs) are vulnerable to adversarial noises. Adversarial training is a general strategy to improve DNN robustness. But training a DNN model with adversarial noises may result in a much lower accuracy on clean data, which is termed the trade-off between accuracy and adversarial robustness. Towards lifting this trade-off, we propose an adversarial training method that generates optimal adversarial training samples. We evaluate our methods on PathMNIST and COVID-19 CT image classification tasks, where the DNN model is ResNet-18, and Heart MRI and Prostate MRI image segmentation tasks, where the DNN model is nnUnet. All these four datasets are publicly available. The experiment results show that our method has the best robustness against adversarial noises and has the least accuracy degradation compared to the other defense methods. © 2023 SPIE.

ID: 219407 The Cardiac Patient and Neuromodulation, When Anticoagulation Dictates the Intervention

Introduction: Patients with cardiac comorbidities present unique challenges for undergoing interventional pain procedures. Consensus guidelines on safe anticoagulation management are categorized by procedure, patient specific bleeding risk factors, and class of anticoagulation (Table 1, Table 2).1 Specifically, some procedures occur in close proximity to the spinal cord, require large gauge needles and styletted leads, while others are in compressible locations with minimal tissue disruption. Further, pain-induced hypercoagulation increases the risk of thrombo-vascular events.1 This accentuates the importance of interdisciplinary perioperative coordination with the prescribing cardiologist. Case: A 71-year-old male with past-medical-history of CABG, bilateral femoral-popliteal bypass, atrial fibrillation on apixaban and ticagrelor, and multiple cardiac stents presented with intermittent shooting axial back pain radiating to right buttock, lateral thigh, and calf, worsened with activity. MRI demonstrated thoracic myelomalacia, multi-level lumbar disc herniation, and moderate central canal stenosis. An initial multi-model treatment approach utilizing pharmacologic agents, physical therapy, ESI's, and RFA failed to alleviate symptoms. After extensive discussion with his cardiologist, he was scheduled for a three-day SCS trial. Ticagrelor and apixaban were held throughout the 3-day trial and for 5 and 3 days prior, respectively, while ASA was maintained. Successful trial with tip placement at T6 significantly improved function and pain scores (Figure 1). Upon planned percutaneous implant, the cardiologist recommended against surgical implantation and holding anticoagulation. Alternatively, the patient underwent bilateral lumbar medial branch PNS implant with sustained improvement in lower back symptoms. However, he contracted COVID, resulting in delayed lead explanation (>60 days) without complication. Conclusion(s): Interventional pain practice advisories are well established for anticoagulation use in the perioperative period.1,2 However, there is limited high-quality research on the appropriate length to hold anticoagulation prior to surgery for high thrombotic risk patients. Collegial decision making with the cardiologist was required to avoid deleterious procedural complications. However, they may be unfamiliar with the nuances between interventions or between trial and implant. Prospective studies have shown that low risk procedures, such as the PNS, may not require holding anticoagulants.3 Other case data has demonstrated post-SCS epidural hematoma with ASA use after being held for 1-week prior to surgery. Our patient was unable to undergo SCS implant and instead elected for a lower risk procedure with excellent efficacy. 4 However, delayed PNS lead extraction due to COVID19 hospitalization presented further risk of infection and lead fracture.5 PNS may prove to be an appropriate treatment option for patients who are anticoagulated and are not SCS candidates.

Association Between COVID-19 Pandemic and Serious Mental Illness: Systematic Review within Salutogenesis Model for Public Health Management

Background: The outbreak of the COVID-19 pandemic, the constant transformation of the SARS-COV-2 virus form, exposure to substantial psychosocial stress, environmental change, and isolation have led to the inference that the overall population's mental health could be affected, resulting in an increase in cases of psychosis. Objective(s): We initiated a systematic review to determine the impact of the SARS-COV-2 virus and its long-term effects-in both symptomatic and asymptomatic cases-on people with or without psychosis. We envisioned that this would give us an insight into effective clinical intervention methods for patients with psychosis during and after the pandemic. Method(s): We selected fifteen papers that met our inclusion criteria, i.e., those that considered participants with or without psychiatric illness and exposed to SARS-COV-2 infection, for this review and were retrieved via Google, Google Scholar, MEDLINE, PubMed, and PsychINFO Database. Key Gap: There is a dearth of research in understanding how COVID-19 affects people with or without a prior personal history of psychosis. Result(s): The systematic review summary provides insight into the state of knowledge. Insights from the systematic review have also been reviewed from the salutogenesis model's perspec-tive. There is moderate evidence of new-onset psychosis during the COVID-19 pandemic in which some antipsychotics treated the psychotic symptoms of patients while treating for COVID-19. Suggestions and recommendations are made for preventive and promotive public health strategies. Conclusion(s): The Salutogenesis model and Positive Psychology Interventions (PPI) provide another preventive and promotive public health management approach.Copyright © 2023 Bentham Science Publishers.

IDDF2023-ABS-0005 Hepatocellular carcinoma (HCC) treatment experience using smart fusion in dialysis patients

BackgroundApproximately 700 dialysis patients are seen at our hospital. Among them are patients with HCC that develop viral hepatitis. Advances in ultrasound systems have improved the accuracy of HCC treatment and diagnosis. This time, we had the opportunity to use microwaves for dialysis patients using Smart Fusion and needle navigation installed in APLIOi800 so that we will report it.MethodsTen dialysis patients were treated from January 2018 to February 2023. An Emprint (Covidien, USA) antenna was used for treatment. Canon APLIOi800(Canon, Tochigi, Japan) was used. The built-in function is Smart Fusion. This method can display ultrasound imaging and volume data from other modalities, such as CT and MRI, in association with positional information using a magnetic sensor. Needle navigation has a function that can confirm the position of the needle. It is possible to treat even when the tumor is overprinted and the visualization is poor due to bubbles. Informed consent was obtained from all patients and the treatment was performed.ResultsIt was possible to visualize all tumors. In this study, CT images were used in 0 cases, and MRI was used in 1 Case. No serious side effects occurred after treatment.ConclusionsUsing this method, it was thought that dialysis patients could be safely and accurately treated.

Imbalanced brain connectome: A possible link behind functional somatic disorders, multiple chemical sensitivity, and long COVID patients

Background: Functional Somatic Disorders (FSDs) are characterized by persistent physical symptoms that cannot be explained by other somatic or psychiatric conditions. Multiple Chemical Sensitivity (MCS) is a non-allergic FSD characterized by odour intolerance and various somatic symptoms being attributed to the influence of toxic environmental chemicals in low, usually harmless doses. The pathophysiology of FSDs are still not clear. Smell and taste complaints were also among the notable symptoms characterizing the covid epidemic and the latest evidence suggests overlaps between long COVID and FSDs. Method(s): The study includes advanced analysis of MRI-derived functional and structural connectomes acquired on a 3 T MR scanner. Furthermore, it includes questionnaires and paraclinical tests, e.g. the Sniffin' Stick olfactory test, Mini-Mental State Examination, and Sino-Nasal Outcome test 22. The pilot part of the project included 6 MCS patients who were compared with 6 matched healthy participants. Later follow-up included analysis of 8 multiorgan FSD and 4 post-COVID patients. Result(s): The MCS group showed important brain structural connectivity differences in 34 tracts. Notably, for MCS patients, the olfactory cortex (especially in the right hemisphere) showed decreased connectivity with regions in the emotional system. Conclusion(s): We plan to extend these findings with whole-brain modelling of the functional connectivity in the patient groups. Long-term this could be used as a 'fingerprint' which could help with diagnosis and treatment monitoring in FSDs as well as with new diagnoses such as long-COVID.Copyright © 2023

Cannabis-Induced Catatonia in a 15-Year-Old Male: A Case Report

Introduction: Catatonia is a syndrome of primarily psychomotor disturbances most common in psychiatric mood disorders but that also rarely has been described in association with cannabis use. Case Presentation: A 15-year-old White male presented with left leg weakness, altered mental status, and chest pain, which then progressed to global weakness, minimal speech, and a fixed gaze. After ruling out organic causes of his symptoms, cannabis-induced catatonia was suspected, and the patient responded immediately and completely to lorazepam administration. Discussion(s): Cannabis-induced catatonia has been described in several case reports worldwide, with a wide range and duration of symptoms reported. There is little known about the risk factors, treatment, and prognosis of cannabis-induced catatonia. Conclusion(s): This report emphasizes the importance of clinicians maintaining a high index of suspicion to accurately diagnose and treat cannabis-induced neuropsychiatric conditions, which is especially important as the use of high-potency cannabis products in young people increases.Copyright © 2023, State Medical Society of Wisconsin.

Post-Covid Myocarditis Simulating Acute Coronary Syndrome

Background: Acute myocarditis corresponds to an acute inflammation of the myocardium whose origin is most often viral. Several viruses can be incriminated to note the parvovirus B19, the virus herpes of the group 6 and to a lesser degree the virus of the hepatitis C (VHC) [18,19]. Since 2019 and with the discovery of SARS COV2 some cases of myocarditis associated with covid have been noted, this last association is rare and is present in only 5% of cases [8]. The diagnosis of myocarditis is sometimes difficult and can lead to confusion with acute coronary syndrome, especially in cases of ST-segment elevation on the EKG, hence the interest of magnetic resonance imaging, which has made it possible in recent years to reduce the rate of unnecessary coronary angiography, especially in the case of young subjects with no cardiovascular risk factors. in this context we report the case of a 33 year old patient with no cardiovascular risk factors and no medical or surgical antecedents who was admitted to the emergency department for the management of acute chest pain related to acute post-covid myocarditis, the patient was initially admitted to the cardiology intensive care unit where he was put in condition and under analgesic treatment and under therapeutic protocal of covid 19 and under anticoagulation based on low molecular weight heparin at preventive dose with a good clinical evolution he was transferred thereafter to the clinical cardiology then declared outgoing under treatment of covid 19 with an appointment of control in 1 month.

Measuring the impact of the COVID-19 pandemic on breast cancer screening in Puerto Rico

Introduction: The COVID-19 pandemic has caused major changes to healthcare services, especially those related to early detection and screening practices like breast cancer. In Puerto Rico, breast cancer is the main cause of death, representing 18.9% of cancer deaths in women, making early detection even more important to prevent morbidity and mortality. This study aims to describe the impact of COVID-19 on breast cancer screening and assess differences in health utilization by age group and health regions in Puerto Rico. Method(s): This study used data on breast cancer screening medical claims from Puerto Rico Track, a project in collaboration with the Puerto Rico Public Health System and the Puerto Rico Institute of Statistics that aims to assess health access and utilization patterns in Puerto Rico. Claims including unilateral and bilateral mammography, sonommamography, and MRI were analyzed. Descriptive statistics and percentual changes between the COVID-19 baseline year (2016) compared with 2020 and 2021 were performed (overall, by age-group and health region). Result(s): A total of 193,793 screening tests were performed in 2016, compared to 66,463 in 2020, and 89,322 in 2021. Overall, a third of the medical claims for breast cancer screening (33.2%) were in the age group of 51-60 years. An overall decreasing percentual change was observed comparing 2016 vs. 2020 (65.7%), where the age group with the broadest gap reduction were among women 41-50 years old (68.2%). When comparing medical claims of 2016 (193,750) versus 2021 (89,320) (pre and post pandemic), an important decreasing change (53.9%) was observed. The age group with the highest decrease comparing 2016 to 2021 was the 41-50 years one (68.2%). The Western region of Mayaguez/Aguadilla had the highest decreasing percentual change, with a reduction of 73.6% in 2020 compared to 2016, and 62.6% when compared 2021 with 2016. Conclusion(s): Breast cancer screening was notably affected by the COVID-19 pandemic in Puerto Rico. A pattern of decreasing breast cancer screening was observed by health regions and by age. These efforts provide evidence of the need of tailored evidence-based interventions to increase breast cancer screening in the island.

BIMEKIZUMAB MAINTAINED IMPROVEMENTS IN EFFICACY ENDPOINTS AND HAD A CONSISTENT SAFETY PROFILE THROUGH 52 WEEKS IN PATIENTS WITH NON-RADIOGRAPHIC AND RADIOGRAPHIC AXIAL SPONDYLOARTHRITIS: RESULTS FROM TWO PARALLEL PHASE 3 STUDIES

BackgroundBimekizumab (BKZ), a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A, met all primary/secondary endpoints at Week (Wk) 16 in patients (pts) with active non-radiographic axial spondyloarthritis (nr-axSpA) and radiographic axSpA (r-axSpA;i.e., ankylosing spondylitis), in the parallel phase 3 BE MOBILE 1 and 2 studies, respectively.[1,2]ObjectivesTo assess efficacy and safety of BKZ in these pts up to Wk 52.MethodsBE MOBILE 1 (NCT03928704) and 2 (NCT03928743) both involved a 16-wk placebo (PBO)-controlled and 36-wk maintenance period.[1,2] Pts were randomised to subcutaneous BKZ 160 mg Q4W (BKZ) or to PBO then BKZ from Wk 16 (PBO/BKZ).Results220/254 (86.6%) randomised pts with nr-axSpA and 298/332 (89.8%) with r-axSpA completed Wk 52. Efficacy was sustained to Wk 52 in both studies (Table 1). ASAS40 responses in BKZ-randomised pts increased from Wk 16 (nr-axSpA: 47.7%;r-axSpA: 44.8%;non-responder imputation [NRI]) to Wk 52 (60.9%;58.4%;NRI) with high levels of efficacy across TNFi-naïve and TNFi-IR populations (Table 1). At Wk 52, ASDAS <2.1 was achieved by 61.6% and 57.1%, and ASDAS <1.3 by 25.2% and 23.4%, of BKZ-randomised pts with nr-axSpA and r-axSpA, respectively (Figure 1). Wk 16 reductions from baseline in objective signs of inflammation (MRI, hs-CRP), and improvements in function (BASFI) and ASQoL, were maintained through 52 wks. Efficacy at Wk 52 was similar in PBO/BKZ-treated and BKZ-randomised pts (Table 1).At Wk 52, 75.0% (183/244) of pts with nr-axSpA and 75.5% (249/330) of pts with r-axSpA had ≥1 treatment-emergent adverse event (TEAE) on BKZ;the most frequent (% pts) TEAEs by preferred term (MedDRA v19.0) were nasopharyngitis (nr-axSpa: 12.3%;r-axSpA 9.1%) and upper respiratory tract infection (9.4%;6.4%);few COVID-19 infections were reported (7.0%;2.1%). Incidence (pts/100 pt years) of serious TEAEs were low (4.4;7.1);no major adverse cardiovascular events, active tuberculosis cases, serious COVID-19 infections, or deaths were reported. Most incidences of fungal infection (19.6;14.9;none serious or systemic) were Candida (12.8;8.3) and mild to moderate;two pts in both studies discontinued the study due to Candida infections. Incidence of IBD (1.0;1.0) and uveitis (1.5;2.4) were low.ConclusionAcross the axSpA spectrum, BKZ resulted in sustained efficacy to Wk 52. No new safety signals were observed, consistent with the Wk 24 safety profile.[1,2]References[1]Deodhar A. Ann Rheum Dis 2022;81:772–3;2.[2]van der Heijde D.
