Antibiotics in Paediatrics: A Boon or a Bane?

Antibiotics play an essential role in antimicrobial therapy. Among all the medications in children, the most commonly prescribed therapy is antibiotics and is currently the indispensable means to cure transmissible diseases. Several categories of antibiotics have been introduced into clinical practice to treat microbial infections. Reducing the unnecessary use of antibiotics is a global need and priority. This article aims to provide better knowledge and understanding of the impact of the early use of antibiotics. This article highlights the proper use of antibiotics in chil-dren, detailing how early and inappropriate use of antibiotics affect the gut microbiome during normal body development and consequently affect the metabolism due to diabetes mellitus, obe-sity, and recurrence of infections, such as UTI. Several new antibiotics in their development stage, newly marketed antibiotics, and some recalled and withdrawn from the market are also briefly discussed in this article. This study will help future researchers in exploring the latest information about antibiotics used in paediatrics.Copyright © 2023 Bentham Science Publishers.

Total Stromal Fraction (TSF)-Fortified Adipose Tissue-Derived Stem Cells Source: An Emerging Regenerative Realm Against COVID-19 In-duced Pulmonary Compromise

The inception of the COVID-19 pandemic has jeopardized humanity with markedly dam-pening of worldwide resources. The viral infection may present with varying signs and symptoms, imitating pneumonia and seasonal flu. With a gradual course, this may progress and result in the deadliest state of acute respiratory distress syndrome (ARDS) and acute lung injury (ALI). More-over, following recovery from the severe brunt of COVID-19 infection, interstitial portions of alve-oli have been found to undergo residual scarring and further to have compromised air exchange. Such alterations in the lung microenvironment and associated systemic manifestations have been recognized to occur due to the extensive release of cytokines. The mortality rate increases with advancing age and in individuals with underlying co-morbidity. Presently, there is no availability of specific antiviral therapy or any other definitive modality to counter this progressive worsening. However, we believe principles and advancing cell-based therapy may prove fruitful in subjugating such reported worsening in these patients. This article reviews eminent knowledge and relevant ad-vancements about the amelioration of lung damage due to COVID-19 infection using adipose tis-sue-derived-total stromal fraction (TSF).Copyright © 2022 Bentham Science Publishers.

Unusual case of Obesity and Hypoventilation in Childhood

Objectives Childhood obesity can be monogenic or polygenic in etiology and is associated with significant morbidities. Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation, and neural crest tumor (ROHHHAD[NET]) syndrome, is a rare autonomic and respiratory pediatric disorder presenting with rapid weight gain in early childhood, hypothalamic-pituitary dysfunction, central hypoventilation, and an association with neural crest tumors. Methods A 6-year-old Asian girl with abnormal weight gain since the age of 3 years, presented to the pediatrician's office due to pulse oximeter readings in the 60s at home. Parents were monitoring saturations at home as a way of screening for COVID-19 infection. The pediatrician confirmed hypoxemia and transferred the patient to the Children's Medical Center emergency department on oxygen via EMS. She had occasional snoring and nighttime cough, but no history of respiratory distress, or signs of infection. There was no hyperphagia, neonatal hypoglycemia, or developmental or behavioral concerns. On examination her body weight was 30 kg (+1.56 SD) and height was 113 cm (-1.46 SD) with a body mass index (BMI) of 23.4 kg/m2 (+2.33 SD). No acanthosis nigricans, cushingoid features, or respiratory distress were noted on examination. In the intensive care unit, she was diagnosed with central hypoventilation requiring mechanical ventilation. Her laboratory work-up revealed central hypothyroidism (low Free T4 of 0.64 ng/dl, TSH 1.553 microIU/L). Other anterior pituitary hormones were normal (adrenocorticotropic hormone, 16.3 pg/mL;cortisol, 10.7 mug/dL;prolactin, 9.95 ng/ml;Insulin-like growth factor-1, 83 ng/mL;and IGF binding protein 3, 3.02 mg/L). Genetic investigations revealed no known mutations in the PHOX2B gene, making a diagnosis of central hypoventilation syndrome unlikely. Results Rapid onset weight gain around 3 years of age, central hypoventilation, and anterior pituitary hormone deficiency in our patient with negative PHOX2B is consistent with a clinical diagnosis of ROHHHAD[NET]. Our patient was started on levothyroxine;received tracheostomy for mechanical ventilation;and gastrostomy for pharyngeal dysphagia. She is doing well, goes to school, and is tolerating trials off the ventilator during the day. Conclusions ROHHAD is an important differential to consider for any child with rapid and early obesity and hypoventilation as early diagnosis is critical in improving the clinical management and the prognosis.

Hemolysis and COVID-19 infection: A fatal combination - An interesting series of three cases

COVID-19 has wreaked havoc ever since its inception and with the protean manifestations of the disease, it is imperative that progressively data are added to the literature. COVID-19 infection is a multisystem disorder with a wide range of clinical symptomatology. Recent information garnered has laid emphasis on pathological changes at microvascular level causing thrombotic/hemostatic defects, leading to the assorted clinical presentation. We present a consortium of three confirmed COVID-19 cases whose hospital course got convoluted with grave hematological complications in the form of hemolytic uremic syndrome and autoimmune hemolytic anemia. Regrettably, all three patients succumbed to their illness.

Utilization of Plastic Waste as a Partial Replacement of Coarse Aggregates in Concrete

Medical Plastic waste is produced in large quantities in India each year, thus recycling it as a constituent in concrete can help to reduce waste disposal. The pandemic of Covid-19 has also resulted in increased production of the PP plastic waste. Because medical plastic wastes are harmful to both the environment and human health, using plastic trash in concrete will help to safeguard both the environment and human health Earlier, different research work were undertaken to figure out safe and feasible methods for plastic waste ejection but with scarce land resources and the threat it has posed to the environment has led us to take a step back and think of safe measures for its safe re-utilization. One such approach is utilization of plastic in concrete manufacturing. With a comparatively longer service life, concrete can act as a safe place for plastic utilization. Plastic wastes are employed as coarse aggregate in concrete in various proportions, and their suitability is tested, the impact of employing plastic waste as coarse aggregate replacement is investigated in this study. As part of the investigation of concrete’s plastic inclusion effect, different experimental research are discussed in this study. The current investigation was carried out on M30 grade concrete, with coarse aggregate replaced with medical PP plastic waste at varied proportions of 20%, 40%, 60%, 80% and 100%. The physical and mechanical properties were comparatively analysed, and the replacement value was optimised. Fresh and hardened concrete qualities were tested and the concrete replacement value for coarse aggregate was optimised at 40% partial replacement of natural coarse aggregate by PP plastic in concrete. Fresh and hardened concrete qualities were tested and analysed.

VACCINE-INDUCED THROMBOCYTOPENIA AND THROMBOSIS: SAILING CLOSE TO THE WIND IN A PANDEMIC

SESSION TITLE: Issues After COVID-19 Vaccination Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: Ever since the global introduction of adenovirus-vector COVID-19 vaccines, cases of cerebral venous sinus thrombosis and thrombocytopenia after immunization has been reported, posing a challenge to global effects on vaccine implementation. CASE PRESENTATION: A previously healthy 33 year old male presented to emergency room with altered mental status after a left sided seizure episode at home. Patient had a 1week history of occipital headache after receiving Ad26.COV2·S Johnson and Johnson vaccine 2 weeks prior. MRI showed superior sagittal sinus thrombosis and right high frontal hemorrhage 8.6x4.7x4.9 cm. CT angiography confirmed nearly occlusive thrombosis of superior sagittal sinus with extension to right transverse sinus. Noted to have a hemoglobin of 15, platelet count of 74000, PT/INR 16/1.2 and PTT of 28. Started on intravenous heparin and intubated for GCS of 4. Heparin was stopped due to supra therapeutic PTT of 200 overnight, drop in platelet count to 55 and hemoglobin to 13. Repeat ct head done for change in neurological exam of dilated right pupil, showed frontoparietal hemorrhage 9.3 cmx4.1 cm and 7 mm midline shift. Heparin was reversed with protamine and transfused 1 unit platelets prior to emergent decompressive craniectomy and thrombectomy. Heparin induced platelet antibody and SRA came back positive confirming vaccine induced thrombocytopenia and thrombosis. Treatment was initiated with argatroban and IVIG. Platelet count improved with no further propagation of thrombus. Patient underwent feeding tube and tracheostomy placement after 10 days due to prolonged ventilator weaning period and poor mental status. Patient's neurological status continued to improve significantly over subsequent months in acute rehabilitation facility with only residual left sided hemiparesis. Patient was successfully decannulated and anticoagulation switched to apixaban DISCUSSION: Possible pathophysiology is thought to be due to a trigger in spike protein production after biodistribution of adenovirus vaccine and a subsequent autoimmune response resulting in thrombosis. Similar to HIT, platelet consumption leads to thrombocytopenia and the continued platelet and monocyte activation increases thrombin generation, resulting in thrombosis. CDC advices to maintain a high suspicion of cases with symptoms that may indicate an underlying thrombotic event along with simultaneous thrombocytopenia. Heparin use is discouraged, unless HIT testing is negative. The International Society on Thrombosis and Hemostasis (ISTH), recommend considering non-heparin anticoagulants and high-dose intravenous immunoglobulin (IVIG). While platelet transfusions are avoided, rapid progression with rising ICP may necessitate transfusion to enable neurosurgical intervention CONCLUSIONS: Management of complications including seizures and elevated intracranial pressure (ICP) is essential to reduce morbidity and mortality risk.

COMPARISON OF HIGHER VERSUS LOWER DOSE STEROID ADMINISTRATION IN PATIENTS WITH COVID-19 AND ACUTE HYPOXEMIC RESPIRATORY FAILURE ON INHALED EPOPROSTENOL

SESSION TITLE: Critical Care Management of COVID-19 SESSION TYPE: Original Investigations PRESENTED ON: 10/17/2022 01:30 pm - 02:30 pm PURPOSE: Superimposed bacterial co-infection is common among patients with Coronavirus disease-19 (COVID-19) pneumonia. Incidence of any superimposed infection ranges from 0% to 40%. Up to 50% of COVID-19 patients who died, had concomitant bacterial or fungal infection. Steroids are recommended for the treatment of acute hypoxemic respiratory failure (AHRF) due to COVID-19 and are thought to mitigate inflammatory organ injury. This retrospective study explores a subset of COVID-19 patients receiving Epoprostenol (iEPO) for AHRF and compared two different steroid treatment strategies and the impact on patient outcomes. METHODS: This is a retrospective study of 101 COVID-19 patients with AHRF receiving iEPO and systemic steroids. Patients in the high dose steroid group (n=59) received a minimum of dexamethasone 20mg daily or solumedrol 100mg daily while the standard dose steroid group (n=52) were those who received any lower dose. Patients that were DNR/I were excluded from the study. The primary outcome of the study was the rate of bacterial co-infection defined by positive cultures. Secondary outcome was mortality. RESULTS: Results showed that patients treated with high dose steroids were older (66.77±11.17 vs 60.33±14.49, p0.006) and received a longer treatment course (18 days (12-25) vs 12.5 days (10-17), p 0.004). Univariate and Multivariate analysis showed that higher dose steroids were not associated with increased risk of superimposed bacterial infection (OR 0.96, CI (0.34-2.66), p0.93). The duration of steroids, regardless of the dose, was associated with increased risk of superimposed bacterial infection (OR 1.06, CI (1.01-1.13), p0.033). When adjusted for comorbidities and inflammatory state, there was no significant difference in mortality between patients treated with high dose compared to standard dose steroids (OR 3.60, CI (0.65-19.93), p0.14). A longer duration of steroids was associated with a trend towards improved mortality (OR 0.93, CI (0.87-1.00), p0.072). CONCLUSIONS: Our study suggests that the duration of steroids, rather than dosage, had an effect on patient outcomes. There was no difference in bacterial co-infection rates between the two groups, but infection rates were increased among those who received a longer course of steroid treatment. There was a trend towards lower mortality with increased steroid duration, however, this did not reach statistical significance. Given this trend towards lower mortality, future prospective studies should investigate steroid duration to determine if a longer course of treatment leads to better outcomes in patients with COVID-19 pneumonia and refractory AHRF. CLINICAL IMPLICATIONS: Based on our study, patients should not receive a higher dose or longer duration of steroid treatment given the increased risk of bacterial infection with no definitive improvement in mortality.

Effect of lockdown amid second wave of COVID-19 on environmental noise scenario of the megacity Delhi, India.

This paper analyzes the impact of second wave of COVID-19 lockdown on environmental noise levels of 25 sites in Delhi city and compares the noise scenario during pre-lockdown, lockdown, and post-lockdown periods. The study utilized the noise monitoring data acquired from 25 real-time ambient noise monitoring stations, installed by the Delhi Pollution Control Committee, Delhi, at various sites throughout Delhi city. A significant reduction of up to 10 and 3 dB(A) in day and night equivalent noise levels, respectively, had been observed during the lockdown period as compared to the pre-lockdown and post-lockdown periods. The study also revealed that only nine sites, including four industrial and five commercial zone sites, complied with the ambient noise standards during lockdown period, and no silence or residential zone sites complied with the ambient noise standards even during the lockdown period. A roadmap for environmental noise management and control is suggested. The study also reports the community's perception toward the change in acoustic environment of Delhi city during the lockdown period by conducting an environmental noise perception survey. The present study should be helpful in devising noise control action plans and policy interventions for environmental noise management and control in the metropolitan city Delhi, India.

Being ethically resilient during COVID-19: a cross-sectional study of Indian supply chain companies

Purpose: The present study aims to examine the relationship between techno-ethical orientation and ethical decision-making (EDM) in Indian supply chain companies during the COVID-19 pandemic. It also aims to explore the moderating role of technological frames (TF) in the relationship between techno-ethical orientation and EDM. Design/methodology/approach: The relationship between techno-ethical orientation and EDM is examined using correlation and regression analysis. The moderating effect of five dimensions of TFs (personal attitude, application value, organisational influence, supervisor influence and industry influence) is analysed using structural equation modelling. Findings: The correlation coefficient between techno-ethical orientation and EDM is 0.513. Also, the regression coefficient (β = 0.213) is significant at 0.05, establishing a positive linkage between the two. R-square values showed a 45.2% variation in EDM is explained by techno-ethical orientation. Similarly, all variables of TFs have a positive and significant moderating effect on the relationship between techno-ethical orientation and EDM. Originality/value: This is one of the pioneer studies exploring techno-ethical orientation’s impact on EDM in supply chain companies. © 2022, Emerald Publishing Limited.

Positive reframing as a mediator between gratitude and technostress amongst Indian students during the COVID-19 pandemic

Purpose: The aim of the current study was to examine the previously unexplored relationship between positive reframing as a mediator between gratitude and technostress in Indian students. By examining this relationship, the authors aim to expand the theoretical domain of gratitude research by examining its potential influence on technology-induced stress. Design/methodology/approach: A cross-sectional survey was used to collect and analyze data from 552 Indian college students who participated in graduate and postgraduate programs across various educational institutions in India. Regression and mediation analyses were performed with both IBM SPSS 25 and AMOS. Findings: This study’s data suggest that positive reframing plays an important mediating role between gratitude and technostress. Gratitude also encourages positive reframing, which reduced technostress among the students. Taken together, our data showed that gratitude induces positive reframing, which in turn reduces techno-stress among Indian students in the current study. Research limitations/implications: The sample size in this study is relatively small in relation to the student population in India. The current study relied primarily on quantitative data and analysis and further research could use a mixed-method approach to better understand the underlying mechanisms between positive reframing, gratitude and technostress. The results are derived under an extreme coronavirus disease 2019 (COVID-19) pandemic situation;therefore, the results cannot be generalized to normal times. Practical implications: The paper includes implications for teachers, academic leaders, parents and civil society. Originality/value: Overall, the relationship between positive reframing, gratitude and technostress has not been thoroughly explored. To the best of the authors' understanding, this is the first study to examine the influence of gratitude on technology-induced stress and the role of reframing. © 2022, Emerald Publishing Limited.

Venetoclax, Obinutuzumab and Atezolizumab (PD-L1 Checkpoint Inhibitor) for First-Line Treatment for Patients with Chronic Lymphocytic Leukemia (CLL)

Background: Dysfunction of T cells, NK cells and other immune subsets is common in patients (pts) with CLL. Venetoclax (VEN), a BCL-2 inhibitor and obinutuzumab (OBIN), a CD20 monoclonal antibody (mAb) are approved for pts with CLL (Fischer, NEJM 2019). Atezolizumab, a PD-L1 checkpoint inhibitor (CPI), is approved for melanoma, lung cancer and other solid tumors. Preclinical studies showed synergy of VEN and CD20 mAb with CPI (Kohlhapp, Cancer Discovery 2021;Westin, Lancet Oncology 2014). Clinical studies showed activity of PD1 inhibition in pts with Richter's transformation, but not CLL (Ding, Blood 2017;Jain, ASH 2018). To our knowledge, no prior study has evaluated PD-L1 inhibition in pts with CLL, nor combined CPI, VEN and OBIN. We hypothesized that combined VEN, OBIN and atezolizumab will be synergistic. Methods: This is an investigator-initiated Phase II trial of combined VEN, OBIN and atezolizumab in pts with previously untreated CLL meeting 2008 IWCLL treatment criteria (NCT02846623). Eligibility criteria included age ≥18 years, adequate organ function (total bilirubin ≤1.5 x ULN, ALT and AST ≤2.5 x ULN, creatinine ≤1.5 x ULN). OBIN was given at a flat dose of 100mg IV Cycle (C)1 Day (D)1, 900 mg C1D2, 1000mg on C1D8, 1000mg on C1D15 and then 1000mg on C2-9 D1. Atezolizumab was given at a flat dose of 1680 mg IV (split over 2 days) on C1D3-4 and then C2-9D1-2. VEN was initiated at the start of C3 with the weekly dose-escalation (20mg daily to a target dose of 400mg daily) and continued daily until end of C14 (total 12 cycles of VEN). All pts stopped therapy at the end of C14. Response assessments were done with CT imaging and bone marrow aspirate/biopsy with MRD assessment (multi-color flow cytometry;sensitivity 10 -4) at the end of C2 (prior to VEN initiation), end of C6, end of C9, and end of C14. Results: From July 2019 to December 2020, a total of 26 pts were enrolled. The median age was 60 years (range, 21-74). The baseline characteristics are shown in Table 1. A total of 19/26 (73%) had unmutated IGHV gene. Though the study did not restrict pts with del(17p) or mutated TP53, no pt in the current cohort had del(17p)/ mutated TP53. A total of 14 (54%) pts had a baseline lymph node >5cm. The median follow-up is 13.3 months. One pt came off study in C1 (details below). A total of 25 pts initiated VEN. The TLS risk categories at the start of C1 were high (n=9, 36%), medium (n=12, 48%), and low (n=4, 16%). After 2 cycles of OBIN and atezolizumab (prior to VEN initiation), the majority of pts had downgrading of TLS risk category [high (n=2, 8%), medium (n=3, 12%), and low (n=20, 80%)]. After C6 (about 3 cycles of VEN 400mg daily), bone marrow undetectable (U)-MRD rate was 19/25 (76%);4/25 (16%) had low+ MRD and 2/25 (8%) had high+ MRD. After C9 (about 6 cycles of VEN 400mg daily), among the 21 pts (4 pts have not reached this time-point), the bone marrow U-MRD rate was 18/21 (86%);2/21 (10%) had low+ MRD and 1/21 (5%) had high+ MRD. A total of 14 pts completed C14 (9 pts have not reached this time-point;2 pts came off study prior to completing C14, details below);13/14 (93%) achieved bone marrow U-MRD and 1/14 (7%) has low+ MRD. No patient had disease progression or MRD relapse so far. One pt died (details below). Three pts came off study (one developed retroperitoneal hematoma after receiving enoxaparin for DVT in C1;one developed CPI-induced colitis and removed from the study in C10;one died from COVID-19 pneumonia in C14 while in bone marrow U-MRD remission). Grade 3-4 neutropenia occurred in 14/26 (54%) pts. Grade 3 thrombocytopenia occurred in 5/26 (19%) pts;no pt had G4 thrombocytopenia. A total of 4 pts developed CPI-induced toxicities (colitis, G3, n=1;mucositis, G3, n=1;nephritis, G2, n=1;myositis, G2, n=1). A total of 10/25 (40%) pts had dose reduction of VEN, the majority due to neutropenia. Atezolizumab was discontinued early in 3 pts due to CPI-induced toxicities. Laboratory correlative studies including scRNAseq and CyTOF are ongoing. Conclusions: Treatment with combined VE , OBIN and atezolizumab leads to high rate of early U-MRD remission with 76% bone marrow U-MRD remission at the end of C6 (about 3 cycles of VEN 400mg daily). Four pts had CPI-induced toxicities. The enrollment in this trial continues and updated data and correlative studies will be presented at the ASH meeting.

Combined Ibrutinib and Venetoclax for First-Line Treatment of Patients with Chronic Lymphocytic Leukemia (CLL): Focus on Long-Term MRD Results

Background: Ibrutinib (IBR) and venetoclax (VEN) combination is a highly effective therapy for patients (pts) with CLL (Jain, NEJM 2019;Wierda, ASH 2020;Kater, EHA 2021). We previously reported results of the first-line cohort of a phase II trial of combined IBR and VEN for high-risk pts with CLL (Jain, NEJM 2019;Jain, JAMA Oncology 2021). Here we report updated data for these pts with focus on MRD. Methods: Pts with previously untreated CLL meeting IWCLL treatment criteria were enrolled. All pts had at least one high-risk feature: del(17p), mutated TP53, del(11q), unmutated IGHV, or age ≥65 years (yrs). Pts received IBR 420 mg daily for 3 cycles followed by addition of VEN (weekly dose-escalation to 400mg daily). Combined therapy was given for 24 cycles (28 days/cycle). Pts with bone marrow (BM) undetectable MRD (U-MRD) (flow cytometry;sensitivity 10 -4) at 24 cycles of combined therapy discontinued both VEN and IBR;MRD+ pts continued IBR. A trial amendment allowed an additional 12 cycles of combined VEN and ibrutinib for pts who remained BM MRD+ after Cycle 24. Response assessments were performed using BM and CT imaging studies (2008 IWCLL criteria). U-MRD was defined as <0.01%;low MRD+ 0.01% to <1%;high MRD+ ≥1%. Progression-free survival (PFS) was assessed as the time from the start of study drug to CLL progression, Richter transformation, or death from any cause. Blood MRD was monitored every 6 months in pts off treatment or on ibrutinib monotherapy beyond 24 cycles of combined treatment. Results: A total of 80 pts were enrolled. Baseline characteristics are shown in Table 1. The median follow-up was 44.1 months. Five pts came off study during 1 st 3 cycles of IBR monotherapy;75 pts initiated VEN. We previously reported that after 12 cycles of the combination, 45/80 (56%) achieved BM U-MRD remission;24/80 (30%) were BM MRD-positive (low MRD+, n=19;high MRD+, n=5). After 24 cycles of the combination, 53/80 (66%) achieved BM U-MRD remission;14/80 (17%) were BM MRD+ (low MRD+, n=13;high MRD+, n=1). Overall, 60/80 (75%) achieved BM U-MRD as the best response. Updated PFS is provided in Figure 1. Of the 53 pts who were BM U-MRD at the end of cycle 24 of the combination, 52 pts had a subsequent blood MRD assessment done in follow-up (1 missed due to COVID-19);51/53 discontinued all therapy, 2 pts continued IBR per treatment physician discretion. With a median time of 18.4 months post Cycle 24, 8 pts had recurrence of blood MRD (defined as MRD ≥ 0.01% in 2 consecutive visits) in follow-up with 1 pt with CLL progression. The sole pt with CLL progression had mutated IGHV with del(11q) and NOTCH1 mutation. The pt had delayed achievement of BM U-MRD with the pt achieving U-MRD for the first time at the end of Cycle 24 of combined therapy. She was noted to have disease progression 22 months off therapy;BTK or PLCG2 mutation were not detected and the patient is currently in clinical remission on acalabrutinib. The time to MRD conversion for these 53 pts is shown in Figure 2. There were 14 pts who were BM MRD+ at the end of cycle 24 of the combination (low MRD+, n=13;high MRD+, n=1). The only pt with high-MRD+ at end of cycle 24 was noted to have Richter transformation at that time. The remaining 13 pts (all low MRD+ in BM, range 0.01-0.56%) continued IBR monotherapy. With a recent trial amendment, MRD+ pts after Cycle 24 could get 12 additional cycles of venetoclax;9/13 pts have resumed VEN. 6/9 pts have achieved U-MRD remission. 2 pts had Richter transformation and 3 pts have died (Jain, JAMA Oncology 2021). Conclusions: We report long term follow-up of combined IBR and VEN in first-line CLL. Remissions were durable with some pts having recurrence of blood MRD in follow-up, which may be an early indicator of relapse. In a small subset of the pts with BM MRD+ disease at 24 cycles of combined therapy, additional VEN appears to lead to U-MRD remission in majority of the pts. Whether this will lead to improved long-term PFS remains to be determined.

Impact of COVID-19 lockdown on ambient noise levels in seven metropolitan cities of India.

The paper analyzed the impact of lockdown on the ambient noise levels in the seventy sites in the seven major cities of India and ascertained the noise scenario in lockdown period, and on the Janta Curfew day in comparison to the pre-lock down period and year 2019 annual average values. It was observed that the majority of the noise monitoring sites exhibited a decrement in ambient day and night equivalent noise levels on the national Janta Curfew day and Lockdown period as compared with the normal working days attributed to the restricted social, economical, industrial, urbanization activity and reduced human mobility. A mixed pattern was observed at a few sites, wherein the ambient day and night equivalent noise levels during Janta curfew day and Lockdown period had been reported to be higher than that on the normal working days. The study depicts the noise scenario during the lockdown and pre-lockdown period for seventy sites in India and shall be instrumental in analyzing the consequences and implications of imposing lockdowns in future on the environmental noise pollution in Indian cities.

DIAPHRAGMATIC CHOREA IN A PATIENT WITH HUNTINGTON'S DISEASE: A CASE REPORT

TOPIC: Pulmonary Physiology TYPE: Fellow Case Reports INTRODUCTION: Respiratory muscle weakness is known to occur in neurodegenerative disorders, including Huntington's disease (HD), and causes 25% of deaths in this population. Though diaphragmatic dystonia has been described in some neurodegenerative diseases, it has not been in HD. In general, little published data exists on overall respiratory function and diaphragmatic movement in HD. CASE PRESENTATION: We describe a 58-year-old male with HD, presenting with progressive dyspnea over 1 year and an accompanying choking sensation upon awakening. Cardiac evaluation with echocardiogram and dobutamine stress test revealed only left ventricular hypertrophy. Family history includes HD in his mother, diagnosed at autopsy age 72;an older brother with HD onset at 53 that died at 62;a maternal aunt with onset in her 50s that died in her 70s. His maternal grandmother and 2 other family members also had involuntary movements believed to be chorea. Most died from respiratory complications. Physical exam showed adequate air entry bilaterally, with clear breath sounds and decreased chest wall expansion. No abdominal paradox or diaphragm dysfunction was appreciated in supine or seated position. On walking oximetry, he became tachypneic and dyspneic after 2 minutes of walking, prompting him to stop. His saturation on room air did not drop below 96%. Heart rate increased to 110 beats per minute. Laboratory panel revealed hemoglobin 13.8 g/dl. A venous blood gas revealed pH 7.38 and pCO2 of 49.A dynamic digital chest radiography (DDR) was performed during two tidal breaths and a forced inspiratory and expiratory maneuver. This revealed decreased bilateral lung inflation. Diaphragmatic contours were elevated bilaterally with a mildly reduced excursion. During the breathing cycle multiple independent diaphragmatic contractions were appreciated on forced inspiration and exhalation resulting in paradoxical motion and dyssynchrony. There was exaggerated use of accessory muscles in the shoulder girdle as a compensatory mechanism. Spasms in the upper airway were also noted throughout the test. Because of covid restrictions, the patient is awaiting pulmonary function tests. DISCUSSION: DDR uniquely provides the opportunity to interrogate respiratory physiology and identify diaphragmatic abnormalities, such as coordination impairments and dyssynchrony compared to static chest radiography;with lower levels of radiation as used in video fluoroscopy. As previously described1, we suggest that the understanding of dyspnea in patients with neurologic disease is enhanced using DDR. CONCLUSIONS: We report the first case of diaphragmatic chorea in a patient with HD using DDR. Future studies are needed to better understand this newly recognized phenomenon of diaphragmatic discoordination and its association with shortness of breath.

Heterogeneity in COVID-19 Patients at Multiple Levels of Granularity: From Biclusters to Clinical Interventions

Several studies have shown that COVID-19 patients with prior comorbidities have a higher risk for adverse outcomes, resulting in a disproportionate impact on older adults and minorities that fit that profile. However, although there is considerable heterogeneity in the comorbidity profiles of these populations, not much is known about how prior comorbidities co-occur to form COVID-19 patient subgroups, and their implications for targeted care. Here we used bipartite networks to quantitatively and visually analyze heterogeneity in the comorbidity profiles of COVID-19 inpatients, based on electronic health records from 12 hospitals and 60 clinics in the greater Minneapolis region. This approach enabled the analysis and interpretation of heterogeneity at three levels of granularity (cohort, subgroup, and patient), each of which enabled clinicians to rapidly translate the results into the design of clinical interventions. We discuss future extensions of the multigranular heterogeneity framework, and conclude by exploring how the framework could be used to analyze other biomedical phenomena including symptom clusters and molecular phenotypes, with the goal of accelerating translation to targeted clinical care.

AR and VR and AI allied technologies and depression detection and control mechanism

Due to the outbreak of COVID-19 pandemic, there exists a situation of worldwide/nationwide lockdown across different countries which results in the growth of new-age technologies including augmented reality (AR) and virtual reality (VR) and their demands. Lockdown situation and social distancing had given sufficient time to develop innovative ideas by using AR/VR technologies. Many global seminars or conferences had been cancelled to practice social distancing and adopt the AR/VR technologies. The consequences of COVID-19 pandemic such as uncertain prognoses and shortages of resources had led to an increase in the depression level among people. This chapter demonstrates the applications of AR/VR and its proposed methodology to integrate the benefits of VR to the standardized mental health treatment process of mental health issues such as depression. The need for effective diagnosis and treatment of mental health combined with the recent advancement of artificial intelligence technologies had led to an increase in explorations in this direction. Deep learning has potentially discovered new learning patterns on the human-machine interface to identify risk factors of mental illness as well as to give optimized therapies. © Springer Nature Switzerland AG 2021.
