Long-term Outcome of Coronavirus Disease-associated Mucormycosis: 1-year Follow-up Study from India.

IMPORTANCE: Invasive fungal infections have recently become a public health problem, particularly in India following the second wave of coronavirus disease 2019 (COVID-19). India harbors the world's largest population of patients suffering from diabetes. What prompted the sudden spike of mucormycosis infections in the COVID pandemic needs investigation. OBJECTIVE: To determine if COVID-19 infection prompted the spike in invasive fungal infections in diabetic population. To determine the long-term outcome of COVID-associated mucormycosis. To determine if COVID-19 infection causes diabetes mellitus transiently. DESIGN: The study was a prospective cohort study comprising patients suffering from mucormycosis. The study was planned from 20 May 2021, until 30 November 2022, to investigate the long-term follow-up (1 year) of mucormycosis patients. SETTING: The study setting was a referral hospital. PARTICIPANTS: All the consecutive patients admitted to this hospital for treatment of mucormycosis were included in the study who consented to it. Intervention(s) (for clinical trials) or exposure(s) (for observational studies): All patients suffering with mucormycosis underwent treatment at this hospital with surgery and injectable systemic antifungal drugs alongside diabetes management. MAIN OUTCOME(S) AND MEASURE(S): Primary outcome measurement was in the form of survival with cure of mucormycosis. Hypothesis being tested was formulated during data collection. RESULTS: The data of 98 participants was collected, but analysis was done after excluding the case of cutaneous mucormycosis (infant patient). Mean age for patients was 55.5 years, varying from 28 to 88 years. In our study, 63.3% of patients with mucormycosis were males and 37.8% were females, of which 55.7% (34) and 58.3% (21) were known diabetics, respectively. Previous history of diabetes mellitus was identified as an underlying comorbid condition in 56.7% of patients, while the rest were diagnosed with new-onset diabetes mellitus. Sugar levels ranged (on admission) from 112 to 494 mg/dL (median 212 mg/dL) for known diabetics and from 132 to 356 mg/dL (median 204 mg/dL) for newly diagnosed diabetics. Other comorbidities included hypertension (19.5%), ischemic heart disease (8.2%), chronic renal illness (3.09%), and one case (1.03%) of postoperative renal cell carcinoma (disease-free). The majority of cases (91.8%) were not vaccinated for COVID-19, while only two patients reported a history of vaccination with two doses, and six others had received only a single dose. At the 1-year follow-up, 57.7% of cases were disease-free, 30.9% had expired, and 11.3% were lost to follow-up. The mean glycated hemoglobin (HbA1c) at the time of admission was found to be statistically significant when compared between known diabetics and newly diagnosed ones [confidence interval (CI)-95%, p ≤ 0.01]. A total of seven patients from the newly diagnosed diabetic group no longer required medicines for diabetes at the end of 1 year (CI-95%, p ≤ 0.01). CONCLUSIONS AND RELEVANCE: Diabetes mellitus, particularly with poor glycemic control, was the single most important factor associated with and predictor of outcome. Contrary to the popular hypothesis, industrial oxygen and oxygen masks were not the reasons for the mucormycosis pandemic. Additionally, immunization against COVID provided protection not only from severe COVID but also from COVID-associated mucormycosis. It is recommended that patients with mucormycosis be followed for longer periods as a few patients could be suffering from transient diabetes, particularly against the backdrop of a pandemic.

An Analysis of the VELNEZ Nasal Pack's Acceptability and Safety for Use During Nasal Surgery: A Prospective Study.

The primary function of nasal packs is to modulate the bleeding, prevent adhesions and obstruction, with least discomfort to the subjects without risking secondary infection. However, both packing and removal of the pack is an unpleasant experience, with the latter being extremely painful. Therefore the need of the hour is a dressing which prioritizes subject comfort without compromising other desired nasal pack properties. Twenty subjects were enrolled in this interventional, open label study. The subjects had 10 hospital visits, starting from baseline (Visit 1) to postoperative day 28 (Visit 10), at regular intervals. The proportion of the population with postoperative pain alleviation and bleeding control failure (within 10 min) were the main objectives. Within 10 min of VELNEZ administration, all 20 participants got their bleeding under control. With VELNEZ, the painful nasal pack removal method was totally avoided because it was biodegradable. No moderate/severe pain, infection and adhesions were reported in any of the subjects, but few subjects reported moderate obstruction until Visit 3 (Discharge Day). In the present study, for participants undergoing nasal surgery, VELNEZ proved to be a secure and reliable nasal pack. Trial Registration: CTRI/2021/09/036437, prospectively registered.

A Post-marketing Surveillance, Single-Centric Study to Evaluate the Safety and Tolerability of VELNEZ as a Space-Occupying Dressing Pack After Ear Surgery.

PURPOSE: The purpose of this study was to evaluate the safety and tolerability of VELNEZ (Datt Mediproducts Pvt. Ltd., New Delhi, India) as a space-occupying dressing for controlling hemorrhage after ear surgery. METHOD: A total of 21 patients were included in an open-label, interventional, single-arm post-marketing surveillance study to investigate the safety and efficacy of the VELNEZ ear pack. The patients were questioned for collecting data related to the subject's safety and comfort, adverse events, site assessment, and otoscopic examination from discharge day to last follow-up (eight follow-up visits) at regular intervals. The standardized questionnaires for VELNEZ tolerability (pain/pressure effect, infection, and general satisfaction) were used after ear surgery. RESULTS:  The average hemorrhage control time was 1.08 ± 0.16 minutes. None of the subjects reported moderate pain at any of the study visits following surgery. This biodegradable ear pack had an average disintegration time of 25.4 days in the ear cavity. No postoperative adverse events or serious adverse events were observed. CONCLUSION: VELNEZ is safe and effective as a space-occupying dressing pack after ear surgery and is well-tolerated by patients.

Pragmatic Coarse-Graining of Proteins: Models and Applications.

The molecular details involved in the folding, dynamics, organization, and interaction of proteins with other molecules are often difficult to assess by experimental techniques. Consequently, computational models play an ever-increasing role in the field. However, biological processes involving large-scale protein assemblies or long time scale dynamics are still computationally expensive to study in atomistic detail. For these applications, employing coarse-grained (CG) modeling approaches has become a key strategy. In this Review, we provide an overview of what we call pragmatic CG protein models, which are strategies combining, at least in part, a physics-based implementation and a top-down experimental approach to their parametrization. In particular, we focus on CG models in which most protein residues are represented by at least two beads, allowing these models to retain some degree of chemical specificity. A description of the main modern pragmatic protein CG models is provided, including a review of the most recent applications and an outlook on future perspectives in the field.

Clinicopathological profile of post-COVID-19 mucormycosis cases: A report from a tertiary care center.

Introduction: Mucormycosis is a fatal fungal infection, which is rare but commonly affects immunocompromised patients. Coronavirus disease 2019 (COVID-19) patients who were immunocompromised, due to comorbid conditions, such as hematological malignancy and diabetes mellitus (DM), and patients on immunosuppressive therapy such as steroid therapy were the important host for mucormycosis infection. Aim: This study aimed to study the clinicopathological correlation of mucormycosis in post-COVID-19 patients. Material and Methods: The study was a retrospective study conducted in the Department of Pathology, Sarojini Naidu Medical College, Agra, Uttar Pradesh, India, over four months from April 2021 to July 2021, and clinically diagnosed mucormycosis cases were included in this study. Clinical details, histology slides, and blocks were reviewed, and the data were analyzed. Three- to four-micrometer sections were taken from the blocks and stained with hematoxylin and eosin, and two more slides were made for each case for periodic acid-Schiff (PAS) and Grocott methenamine silver (GMS) staining. Result: In this study, the maximum cases were above the fifth decade of life. Males were more commonly affected than females with a male-to-female ratio of 2.09:1. Of the total of 65 cases, 46 (70.77%) cases were positive for mucormycosis and 19 (29.23%) cases were negative on histopathological examination and special stain PAS and GMS. A significant correlation was found between mucormycosis-positive cases on steroid therapy and oxygen supply during the treatment for COVID-19 with P- values of 0.001 and 0.027, respectively. Conclusion: For COVID-19 patients with altered glycemic control, receiving steroid therapy and oxygen supply poses a significant threat to the development of mucormycosis.

Comparative evaluation of isoflurane and desflurane for postoperative cognitive decline in elderly patients: A prospective observational pilot study.

BACKGROUND: Approximately 16%-62% of patients undergoing non cardiac surgeries develop postoperative cognitive dysfunction. We compared the incidence of postoperative cognitive dysfunction in older adults aged 60-80 years who underwent open abdominal surgeries under general anaesthesia using isoflurane or desflurane and correlated it with the serum concentration of interleukin 1, interleukin 6, tumour necrosis factor alpha, amyloid ß and S100 on postoperative day 3. METHOD: Forty American Association of Anesthesiologists Physical Classification I or II patients were included after acquiring institutional ethics committee approval, registering in the Clinical Trials Registry - India, and informed written consent. They underwent open abdominal surgery under general anaesthesia and epidurals between 2017 and 2019. Patients with substance abuse or any disorder affecting cognition were excluded. Postoperative cognitive dysfunction was assessed by Stroop test, Wisconsin Card Sorting Test, Trail making test - B, Porteus Maze test, PGI memory scale, mini-mental state examination, and Bender Gestalt test the day before surgery and on the third postoperative day along with blood samples. RESULTS: Thirty-seven percent of the patients developed postoperative cognitive dysfunction. The risk was similar to isoflurane in comparison with desflurane (risk ratio: 0.65, 95% confidence interval: 0.30, 1.40). A significant percentage increase in reaction time for Porteus Maze test and Trail making test - B was noted with isoflurane (6.69 (4.20-8.94) and 8.01 (2.08-12.5), respectively) in comparison with desflurane group (13.01 (9.09-17.33), p = 0.003 and 11.62 (7.5-17.5), p = 0.017, respectively). CONCLUSION: Isoflurane and desflurane had a similar impact on the elderly for developing postoperative cognitive dysfunction and no correlation with any of the biomarkers used in the study on postoperative day 3.

The synthesis of heteroleptic Cu(I) complexes with coumarin-functionalized aminodiphosphine and diimine ligands is described. The complexes show yellow to deep-red phosphorescence in the solid state at ambient temperature with quantum yields up to 21%. The emission color of the complexes can be tuned by systematic modifications in the ligand system.

Functional near-infrared spectroscopy guided mapping of frontal cortex, a novel modality for assessing emergence delirium in children: A prospective observational study.

INTRODUCTION: Despite an 18%-30% prevalence, there is no consensus regarding pathogenesis of emergence delirium after anesthesia in children. Functional near-infrared spectroscopy (fNIRS) is an optical neuroimaging modality that relies on blood oxygen level-dependent response, translating to a mean increase in oxyhemoglobin and a decrease in deoxyhemoglobin. We aimed to correlate the emergence delirium in the postoperative period with the changes in the frontal cortex utilizing fNIRS reading primarily and also with blood glucose, serum electrolytes, and preoperative anxiety scores. METHODS: A total of 145 ASA I and II children aged 2-5 years, undergoing ocular examination under anesthesia, were recruited by recording the modified Yale Preoperative Anxiety Score after acquiring the Institute Ethics Committee approval and written informed parental consent. Induction and maintenance were done with O2, N2O, and Sevoflurane. The emergence delirium was assessed using the PAED score in the postoperative period. The frontal cortex fNIRS recordings were taken throughout anesthesia. RESULTS: A total of 59 children (40.7%) had emergence delirium. The ED+ group had a significant activation left superior frontal cortex (t = 2.26E+00; p = .02) and right middle frontal cortex (t = 2.27E+00; p = .02) during induction, significant depression in the left middle frontal (t = -2.22E+00; p = .02), left superior frontal and bilateral medial (t = -3.01E+00; p = .003), right superior frontal and bilateral medial (t = -2.44E+00; p = .015), bilateral medial and superior (t = -3.03E+00; p = .003), and right middle frontal cortex (t = -2.90E+00; p = .004) during the combined phase of maintenance, and significant activation in cortical activity in the left superior frontal cortex (t = 2.01E+00; p = .0047) during the emergence in comparison with the ED- group. CONCLUSION: There is significant difference in the change in oxyhemoglobin concentration during induction, maintenance, and emergence in specific frontal brain regions between children with and without emergence delirium.

The role of point of care thromboelastography (TEG) and thromboelastometry (ROTEM) in management of Primary postpartum haemorrhage: A meta-analysis and systematic review.

Background: The utility of instantaneous evaluation of coagulation during primary postpartum haemorrhage (PPH) is paramount in the context of empirical blood product transfusion-related risk of dilutional and consumptive coagulopathy and circulatory overload. Methods: A profound screening of electronic databases till August 15, 2022 was carried out after being enlisted in PROSPERO (CRD42021275514). Randomized control studies, comparative cohort studies, and cross-sectional studies comparing point-of-care viscoelastic test guided blood product transfusion with empirical transfusion in patients with PPH were included. Results: We retrieved five studies, with a total of 1914 parturient with PPH. Patients receiving transfusion based upon point of care viscoelastic tests had lesser risk of having emergency hysterectomy (Odds ratio (OR) = 0.55, 95% CI 0.32-0.95, I2 = 7%), transfusion-associated circulatory overload (TACO) (OR = 0.03, 95% CI 0.00-0.50), reduced transfusion of fresh frozen plasma (OR = 0.07, 95% CI 0.04-0.14, I2 = 89%), platelets (OR = 0.51, 95% CI 0.28-0.91, I2 = 89%), packed red blood cell transfusion (OR = 0.70, 95% CI 0.55-0.88, I2 = 89%), and had better cost-effective treatment [Mean difference (MD) = -357.5, 95% CI - 567.75 to -147.25, I2 = 93%] than patient received empirical transfusion. However, there was no significant difference in the requirement of ICU admissions (OR = 0.77, 95% CI = 0.46-1.29, I2 = 82%). No mortality was detected across the studies. Conclusions: Point of care viscoelastic assessment guided transfusion in PPH confederates with reduced morbidity. Nevertheless, more studies on the triggering values for transfusion, long-term survival, and cost-benefit in patients with PPH are warranted to establish its utility.

An in silico osmotic pressure approach allows characterization of pressure-area isotherms of lipid monolayers at low molecular areas.

Surface pressure-area isotherms of lipid monolayers at the air-water interface provide essential information about the structure and mechanical behaviour of lipid membranes. These curves can be readily obtained through Langmuir trough measurements and, as such, have been collected for decades in the field of membrane biochemistry. However, it is still challenging to directly observe and understand nanoscopic features of monolayers through such experiments, and molecular dynamics (MD) simulations are generally used to provide a molecular view of such interfaces. In MD simulations, the surface pressure-area (Π-A) isotherms are generally computed using the Kirkwood-Irving formula, that relies on the evaluation of the pressure tensor. This approach, however, has intrinsic limitations when the molecular area in the monolayer is low (typically < 60 Å2 per lipid). Recently, an alternative method to compute Π-A isotherms of surfactants, based on the calculation of the three-dimensional osmotic pressure via the implementation of semipermeable barriers was proposed. In this work, we investigate the feasibility of this approach for long-chain surfactants such as phospholipids. We identify some discrepancies between the computed values and experimental results, and we propose a semi-empirical correction based on the molecular structure of the surfactants at the monolayer interface. To validate the potential of this new approach, we simulate several phosphatidylcholine and phosphatidylethanolamine lipids at various temperatures using all-atom and coarse-grained force fields, and we compute the corresponding Π-A isotherms. Our results show that the Π-A isotherms obtained using the new method are in very good agreement with experiments and far superior to the canonical pressure tensor-based method at low molecular areas. This corrected osmotic pressure method allows for accurate characterization of the molecular packing in monolayers in various physical phases.

Phase-Dependent Long Persistent Phosphorescence in Coumarin-Phosphine-Based Coinage Metal Complexes.

A coumarin functionalized aminodiphosphine has been introduced as a bidentate ligand in coinage metal chemistry. Mono-, di-, and trimetallic copper and silver complexes were synthesized with this ligand. The hybrid character of the ligand led to compounds with rich luminescence properties. These include coumarin-based blue fluorescence, observed as a sole emission in solution at room temperature, and green phosphorescence, which is efficient at low temperatures and dominates the spectra of the metal complexes. In the rigid environment of frozen solutions, the green phosphorescence shows an unusually long (for metal complexes) decay on the seconds timescale in high quantum yield. In addition, a red phosphorescence, which may be assigned to the triplet state localized in the phosphine-M3 Cl2 (M=Cu, Ag), is observed for the trinuclear complexes at low temperature. Neither the second-long phosphorescence nor the red emission is observed for the coumarin ligand, thus they must be a result of the coordination to coinage metal clusters. The excited states in these compounds were also investigated by femtosecond transient absorption spectroscopy and quantum chemical calculations.

Impact of intravenous dexamethasone on the initiation and recovery of atracurium in children: A double-blinded randomized controlled trial.

BACKGROUND: Chronic steroid intake has been associated with attenuation of neuromuscular block. Despite some promising animal and adult studies, the effect of a single dose of intravenous dexamethasone on neuromuscular blockers is not well established. Thus, the present study aimed to demonstrate the effect of dexamethasone given at the time of induction for the prevention of PONV on the action of neuromuscular blockers in children undergoing elective surgery. METHOD: After obtaining approval from the Institute Ethics Committee and written informed parental consent, 100 ASA I and II children aged 4-15 years undergoing elective surgery randomized to receive either: 0.15 mg/kg (maximum of 5 mg) of dexamethasone diluted to a total volume of 2 ml with 0.9% saline (n = 50) or 2 ml of 0.9% saline (n = 50) at the time of induction. The time interval between application of atracurium and maximum T1 depression, 25% twitch height recovery of T1, amid 25% and 75% twitch height recovery of T1, amid the 25% twitch height recovery of T1 and recovery of the neuromuscular block to a TOF ratio of 0.9, and in between the initiation of atracurium injection till the recovery of the neuromuscular block to a TOF ratio of 0.9 was defined as onset time, clinical duration, recovery index, recovery time, and total recovery period, respectively, and recorded. RESULTS: The onset time and recovery index time were lower (1.96 ± 0.39, 8.04 ± 2.14, respectively) with dexamethasone in comparison with saline (2.01 ± 0.51, 8.9 ± 3.4, respectively) but not statistically significant. The clinical duration, recovery time, and total recovery period were similar. CONCLUSION: Application of a single bolus dose (0.15 mg/kg) of dexamethasone during induction does not attenuate atracurium-induced neuromuscular blockade in children.

Comparative evaluation of intraoperative dexmedetomidine versus lidocaine for reducing postoperative cognitive decline in the elderly: a prospective randomized controlled trial.

INTRODUCTION: Neuroinflammation, neuronal cytotoxicity, and apoptosis due to exposure to anaesthetic agents are often implicated in postoperative cognitive dysfunction (POCD). Lidocaine and dexmedetomidine have been shown to suppress the neuron-specific markers of inflammation, and we aimed to compare their neuroprotective efficacy in elderly patients. MATERIAL AND METHODS: This prospective randomized control study compared the incidence of POCD in ASA I/II patients aged 60 to 80 years without any history of substance abuse or any disorder affecting cognition. Dexmedetomidine and lidocaine were administered intraoperatively, and their effects on POCD were correlated with serum levels of IL-1, IL-6, TNF-a, amyloid-ß, and S100 on postoperative day 3. POCD was assessed by the Stroop test, Trail making test-B, Porteus Maze test, Mini-Mental State Examination (MMSE), and Montreal Cognitive Assessment (MoCA) on the day before surgery and the third postoperative day, along with blood samples. RESULTS: Demographic parameters, anaesthesia duration, exposure to anaesthetic gases, intraoperative opioid use, and blood transfusion were similar in the lidocaine ( n = 31) and dexmedetomidine ( n = 29) groups. The incidence of POCD was 29.03% in the lidocaine group and 24.1% in the dexmedetomidine group ( P = 0.77). On postoperative day 3, IL-1 levels increased by 449% with lidocaine and 202% with dexmedetomidine ( P = 0.03). TNF-a, IL-6, and S-100ß levels increased similarly in both groups. There was no significant correlation between percentage changes in neuropsychological tests and biomarkers. CONCLUSIONS: There was no significant difference in the incidence of POCD, but dexmedetomidine had a better anti-inflammatory effect in terms of lesser rise of postoperative IL-1 compared to lidocaine.

Assessing the SpO2 in a random population - Looking for the best among fingers.

Context: Pulse oximetry is one of the most revolutionary methods used to monitor the patients in the clinical setting, particularly intensive care and anesthesia. We usually use the index or middle finger to measure SpO2 values, but little is known about the inter-digital differences that exist between the fingers. Aim: We aim to compare the peripheral capillary oxygen saturation among fingers of both hands. A total of 93 healthy volunteers aged between 18 and 50 years participated in the study. Materials and Methods: Their SpO2 values were recorded from each finger with at least 1 minute of resting interval. Their blood pressure, heart rate, and body temperature were recorded as well. Result: A total of 930 measurements were obtained from 93 volunteers. The highest average SpO2 value of right-handed volunteers was measured from the left little finger (98.48 ± 0.62) of right-handed volunteers, and it was statistically significant when compared with the right ring finger, right little finger, left thumb, left index, left middle finger, and left ring finger. The highest average SpO2 from left-handed volunteers was obtained from the right index finger, but it was statistically insignificant. Conclusion: We assume ethnic and climatic differences to play a role in contradictory results noted from previous studies conducted, and this needs to be investigated further. It is recommended that multiple readings may be obtained from other fingers as well before coming to any conclusion as inter-finger variability cannot be ignored.

Glimpse into the Lifestyle of Doctors.

Background: Lifestyle disorders are on rise world over. Also, the role of doctors as leaders in propagating healthy lifestyles needs to get a reality check. Aims and Objectives: This study aimed to investigate the prevalence of lifestyle disorders, eating habits, nutrition patterns, and lifestyle of doctors by assessing health-related behaviours considering gender and other relevant demographic parameters. The objectives of the present study are to find out the relationship of lifestyle disorders among doctors and to study lifestyle disorders and related behaviour among male and female doctors and other subgroups. Materials and Methods: Online survey was conducted using Googledoc in June to August 2021. Descriptive statistical analysis has been carried out in the present study. The student's t-test (two tailed, independent) has been used. Results: About 50% rated a happiness quotient of 7 and 8. Surgeons had more diabetes and hypertension than physicians. Prevalence of hypertension was more in self-employed males versus males in job. About two-third participants scored ≥ 80% on healthy lifestyle score. Conclusion: Our results call for a well-thought strategy to overcome the financial and technological hindrances to accurately identify health risk factors and plan corrective interventions. A healthy lifestyle both in terms of diet and exercise should be incorporated into the schedules of doctors.

Clinical profile of ChAdOx1 nCoV-19- and BBV152-vaccinated individuals among hospitalized COVID-19 patients: a pair-matched study.

Background: COVID-19 infections among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-vaccinated individuals are of clinical concern, especially in those requiring hospitalization. Such real-world data on ChAdOx1 nCoV-19- and BBV152-vaccinated individuals are scarce. Hence, there is an urgent need to understand their clinical profile and outcomes. Methods: A 1:1 pair-matched study was performed among vaccinated and unvaccinated COVID-19 patients admitted between March 2021 and June 2021 at a tertiary care centre in New Delhi, India. The vaccinated group (received at least one dose of ChAdOx1 nCoV-19 or BBV152) was prospectively followed till discharge or death and matched [for age (±10 years), sex, baseline disease severity and comorbidities] with a retrospective group of unvaccinated patients admitted during the study period. Paired analysis was done to look for clinical outcomes between the two groups. Results: The study included a total of 210 patients, with 105 in each of the vaccinated and unvaccinated groups. In the vaccinated group, 47 (44.8%) and 58 (55.2%) patients had received ChAdOx1 nCoV-19 and BBV152, respectively. However, 73 patients had received one dose and 32 had received two doses of the vaccine. Disease severity was mild in 36.2%, moderate in 31.4% and severe in 32.4%. Two mortalities were reported out of 19 fully vaccinated individuals. All-cause mortality in the vaccinated group was 8.6% (9/105), which was significantly lower than the matched unvaccinated group mortality of 21.9% (23/105), p = 0.007. Vaccination increased the chances of survival (OR = 3.8, 95% CI: 1.42-10.18) compared to the unvaccinated group. Conclusion: In the second wave of the pandemic predominated by delta variant of SARS CoV-2, vaccination reduced all-cause mortality among hospitalized patients, although the results are only preliminary.

COVID-19 infection in patients with haematological disease - A tertiary centre experience from north India.

This retrospective study was aimed to understand the clinical, laboratory, radiological parameters and the outcome of COVID-19 patients with underlying haematological disease. All patients with known haematological disease admitted with COVID-19-positive status from April to August 2020 in the COVID-19 facility of a tertiary care centre in north India, were included. Their medical records were analyzed for outcome and mortality risk factors. Fifty four patients, 37 males, were included in the study. Of these, 36 patients had haematological malignancy and 18 had benign disorder. Fever (95.5%), cough (59.2%) and dyspnoea (31.4%) were the most common symptoms. Nine patients had severe disease at diagnosis, mostly malignant disorders. Overall mortality rate was 37.0 per cent, with high mortality seen in patients with aplastic anaemia (50.0%), acute myeloid (46.7%) and lymphoblastic leukaemia (40.0%). On univariate analysis, Eastern Cooperative Oncology Group performance status >2 [odd ratio (OR) 11.6], COVID-19 severity (OR 8.2), dyspnoea (OR 5.7) and blood product transfusion (OR 6.4) were the predictors of mortality. However, the presence of moderate or severe COVID-19 (OR 16.6, confidence interval 3.8-72.8) was found significant on multivariate analysis. The results showed that patients with haematological malignancies and aplastic anaemia might be at increased risk of getting severe COVID-19 infection and mortality as compared to the general population.

Effectiveness of electroconvulsive therapy in acute management of delirious mania in COVID-19 positive woman in second trimester pregnancy.

Delirious mania has been described as a state of acute excitement, fluctuating sensorium, affective and catatonic symptoms. Electroconvulsive therapy (ECT) despite being an effective treatment modality in such cases, has been under-utilised during pregnancy, mainly due to safety concerns. Here, we report the effectiveness of ECT in acute management of delirious mania in a 24 weeks pregnant woman who also tested COVID-19 positive during hospitalisation. Patient presented with three weeks history of acute manic excitement with period of altered sensorium and catatonic symptoms with no response to trials of two antipsychotic agents. After organic causes ruled out, patient was planned for ECT while ongoing antipsychotic was continued. After the first ECT session, patient tested positive for COVID-19, though asymptomatic and had to be shifted to COVID-19 isolation facility. Complete resolution of psychiatric symptoms occurred after fifth ECT. All five ECT sessions, including those in COVID-19 isolation facility were carried out under supervision of a multidisciplinary team. None of the ECT sessions had any major adverse event. Symptom remission sustained even following ECT discontinuation. No neonatal or maternal adverse effects observed after an uneventful delivery at 35 weeks. Both mother and child continued to maintain well in follow-up period of one year on oral olanzapine. In this unusual concurrent presentation of mania, delirium and catatonic symptoms during second trimester pregnancy, we highlighted the effectiveness and safety of ECT as a viable treatment modality. Additionally, management challenges posed by patient testing COVID-19 positive and then, administering ECT in COVID-19 isolation facility using personal protective equipment by multidisciplinary team has been highlighted.
