Long COVID and Hybrid Immunity among Children and Adolescents Post-Delta Variant Infection in Thailand.

This study aimed to assess long COVID, and describe immunogenicity against Omicron variants following BNT162b2 vaccination. A prospective cohort study was conducted among children (aged 5-11) and adolescents (aged 12-17) who had SARS-CoV-2 infection from July to December 2021 (Delta predominant period). Long COVID symptoms were assessed by questionnaires at 3 months after infection. Immunogenicity was evaluated by using a surrogate virus-neutralizing antibody test (sVNT) against the Omicron variant. We enrolled 97 children and 57 adolescents. At 3 months, 30 children (31%) and 34 adolescents (60%) reported at least one long COVID symptom, with respiratory symptoms prevailing (25% children and 32% adolescents). The median time from infection to vaccination was 3 months in adolescents and 7 months in children. At 1 month following vaccination, in children who received one-dose and two-dose BNT162b2 vaccines, the median (IQR) sVNT against Omicron was 86.2% inhibition (71.1-91.8) and 79.2% inhibition (61.5-88.9), respectively (p = 0.26). Among adolescents who received one-dose and two-dose BNT162b2 vaccines, the median (IQR) sVNT against Omicron was 64.4% inhibition (46.8-88.8) and 68.8% inhibition (65.0-91.2) (p = 0.64). Adolescents had a higher prevalence of long COVID than children. Immunogenicity against the Omicron variant after vaccination was high and did not vary between one or two doses of the vaccine in either children or adolescents.

A comparative study of mortality differences and associated characteristics among elderly and young adult patients hospitalised with COVID-19 in India.

INTRODUCTION: Studies have shown that elderly have been disproportionately impacted by COVID pandemic. They have more comorbidities, lower pulmonary reserve, greater risk of complications, more significant resource utilization, and bias towards receiving lower-quality treatment. OBJECTIVES: This research aims to determine the characteristics of those who died inhospital due to COVID illness, and to compare these factors between elderly and young adults. METHODS: We conducted a large retrospective study at a government run center in Rishikesh, India, from 1st May 2020 till 31st May 2021, and divided study population into adults (aged 18 to 60 years) and elderly (aged 60 years). We evaluated and compared our data for presenting symptoms, vitals, risk factors, comorbidities, length of stay, level of care required, and inhospital complications. Long-term mortality was determined using telephonic follow-up six months after discharge. RESULTS: Analysis showed that elderly had 2.51 more odds of dying inhospital compared to younger adults with COVID. Presenting symptoms were different for elderly COVID patients. The utilization of ventilatory support was higher for elderly patients. Inhospital complications revealed similar profile of complications, however, kidney injury was much higher in elderly who died, while younger adults had more Acute Respiratory Distress. Regression analysis showed that model containing cough and low oxygen saturation on admission, hypertension, Hospital Acquired Pneumonia, Acute Respiratory Distress Syndrome, and shock, predicted inhospital mortality. CONCLUSION: Our Study determined characteristics of inhospital and long-term mortality in elderly COVID patients and compared them from adults, to help better triaging and policy making in future.

Analysis of Optical Coherence Tomography (OCT) and Optical Coherence Tomography Angiography (OCTA) Parameters in Young Adults after SARS-CoV-2 Infection (COVID-19) Compared with Healthy Young Controls.

PURPOSE: To compare retinal changes in young adults with previous SARS-CoV-2 infection with healthy young controls using optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA). METHODS: This prospective single-center study was conducted at the University Hospital of Zurich, Zurich, Switzerland. Participants were imaged from May to November 2021 using the SOLIX device (Visionix International SAS, Pont-de-l'Arche, France). We performed 12 mm × 12 mm, 6.4 mm × 6.4 mm, 6 mm × 6 mm and 3 mm × 3 mm OCT and OCTA scans, as well as fundus photography of each participant's eyes. RESULTS: In total, 466 participants were imaged. Of these, 233 were healthy controls with negative RT-PCR tests for SARS-CoV-2, 168 were young adults who had a SARS-CoV-2 infection at least 180 days previously, 19 were participants who had a SARS-CoV-2 infection < 180 days previously, and 46 were participants with asymptomatic SARS-CoV-2 infection (i.e., serologically positive but with no symptoms). Compared with healthy controls, statistically significant differences were found for OCTA recordings of the optic disc for the whole image (WI) and WI capillary vessel density, with both being higher in the SARS-CoV-2 group. CONCLUSION: Statistically significant results were only observed for selected variables, and in parts, only unilaterally, with relatively large p values (p = 0.02-0.03). Thus, we did not interpret these as clinically significant, leading to the conclusion that young and otherwise healthy individuals (mainly men) seem to recover from mild COVID-19 infections with no ophthalmological residues.

Post-acute Sequelae of SARS-CoV-2 Infection: Do Indians Fare Better?

INTRODUCTION: The uplift of SARS-CoV-2 infection has necessitated the understanding of long-term consequences in the affected population. This study was driven by a lack of Indian studies to estimate the torment of post-coronavirus disease 2019 (COVID-19) symptoms and the quality of life. METHODS:  This prospective observational study was conducted in a tertiary care centre in South India, between August and November 2020. SARS-CoV-2 hospitalised patients were telephonically questioned regarding the persistence of symptoms along with an assessment of the quality of life using the 15D questionnaire in the first, second, and fourth weeks. Since a majority of the patients had resolution of symptoms by four weeks, the study was not extended for a longer period. RESULTS: The study included 476 patients whose mean length of hospital stay was 7.67 days. Of the patients, 68.7% had mild severity, 24.8% had moderate disease, and 6.5% had severe disease. About 28.4% required oxygen, 8.2% required ICU care, and 1.3% required mechanical ventilation. Myalgia (13.9%), cough (1.3%), and dyspnoea (6.1%) were the predominant persistent symptoms in the fourth-week post-discharge. All the symptoms of health-related quality of life and physical performance improved by the fourth week, which was statistically significant. CONCLUSION: Our study findings are in stark contrast to the studies published from other regions of the world, which show a significant worsening of quality of life even among those with mild illness.

The Second COVID Wave Washes Over New York State

By Oct 30, 2020 nine NYS counties had over 3% positive tests. By Nov 9, 29 counties exceeded 3% positive. By Nov 29, 45 counties out of 62 did. The contagion showed classic spatial diffusion from epicenters with great rapidity. Data on percent of positive COVID tests for 16 days out of 57 between Oct 30 and the Dec 25 crest showed no SE association with percent positive. The 31 rural counties often had significantly higher means and medians than the 31 urban. The sole factor frequently associating with percent positive was 2020 percent Trump vote. The Trump vote signaled risk behaviors that led to epicenters in rural counties spreading COVID to the rest of the state. After early January 2021, the means and medians declined as rapidly as they had built up to the crest, an indication that behaviors changed massively toward interventions, especially in the rural, Trump-voting counties. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Understanding the COVID 19 Conundrum and Decluttering the scientific literature on COVID 19.

As COVID 19 continues to over burden the healthcare system globally, the scientists are relentlessly pursuing research and publishing copious data on relevant managements strategies for the infection. This short communication has attempted to simplify the available information on the subject in a manner that is easy to understand and implement in clinical setting. COVID 19 is not a single disease but a spectrum and should be classified based on clinical, radiological and laboratory parameters. A simple yet powerful way is to classify COVID 19 as COVIN - COVID Infection but no disease; COVIRI - COVID infection with predominant respiratory symptoms; COVIDI - COVID infection leading to an abnormal immune response and COVID S- referring to the sequalae of an acute COVID Infection. A clinical subtype specific approach may result in easier communication between healthcare providers which in turn may improve patient outcomes by providing targeted therapy.

Initial review of pregnancy and neonatal outcomes of pregnant women with COVID-19 infection.

OBJECTIVES: Data regarding the pathogenesis and clinical manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue to emerge, however, there's limited data in regard to maternal and neonatal outcomes. Therefore, we conducted a retrospective analysis of all pregnant women who tested positive for SARS-CoV-2 within Nuvance Health system. METHODS: Data were abstracted from the medical records of each patient and descriptive analysis was performed. Variables included demographics, COVID testing results, symptoms, management, labor course, neonatal information, and complications. RESULTS: Total of 40 patients were identified. Average age was 29.6 years old, 35% were Hispanic, and approximately one in three patients had comorbidities. Of the patients who had repeated testing, the average number of days between first positive test and negative test was 36.8 days (± 19.9 days). Three out of four women reported symptoms. Of the 40 pregnant women who were positive for SARS-CoV-2, 25 of them delivered. About 84% of the women delivered after 37 weeks. Twelve percent of the women delivered under 33 and 6/7 weeks. Most patients had vaginal deliveries (68%) and the remaining had cesarean deliveries. Neonatal outcomes included: mean 1 and 5 min Apgar scores of 8 and 8.8, respectively and the mean birth weight was 3212 g. Twenty neonates were tested for SARS-CoV-2 and were all found to be negative. CONCLUSIONS: Overall, with routine prenatal care and preventive measures, pregnant patients and neonates in our study had good outcomes. At this time, there appears to be no evidence of vertical transmission.

A Statement of Solidarity on COVID-19 Pandemic 2020 by the South Asian Family Physicians.

The World Organization of Family Doctors (WONCA) is a not-for-profit organization and was founded in 1972 by member organizations in 18 countries. WONCA now has 118 Member Organizations in 131 countries and territories with a membership of about 500,000 family doctors and more than 90 percent of the world's population. WONCA has seven regions, each of which has its own regional Council and run their own regional activities including conferences. WONCA South Asia Region is constituted by the national academies and colleges and academic member organizations of this region namely India, Pakistan, Bangladesh, Nepal, Sri Lanka, Bhutan, and the Maldives. In the background of the ongoing COVID 19 pandemic, the office bearers, academic leaders, practitioners, and researchers of primary care from the South Asia Region have issued a solidarity statement articulating the role of primary care physicians.

Fever, flu and family physicians during COVID 19 pandemic 2020 in India.

Fevers - undifferentiated, often unacknowledged, is one of the largest morbidity afflicting in primary care settings and the overall healthcare ecosystem in India. FEVER is probably also the largest public health entity in terms of DALY - (Disability Adjusted Life Years) impacting the working population both in urban as well as rural areas; however, it remains unaddressed by public health programs, which are largely organized through vertical disease-focused national programs. The family physicians see a high volume of undifferentiated fevers throughout the year with seasonal and regional variations in India. Family doctors are not formally linked with the public health programs as India continues to march on selective primary care. Family physicians and medical officers are the most vulnerable for exposure to undifferentiated patient load. The first two health workers who died of COVID 19 in India (Indore) were practicing family physicians. Two mohalla clinic doctors tested positive in Delhi and two other general practitioners have been found to be infected in Mumbai. The media discussions have been on increasing capacity for critical care and the number of ventilators etc., It is also important for the governments to urgently review the functionality of PHCs, CHCs and district hospitals, and create a framework of partnership with standalone family physicians and general practitioners as well as nursing home, small hospitals to play a constructive role in managing the epidemic.
