Second wave of COVID 19 pandemic in India came with unexpected quick speed and intensity, creating an acute shortage of beds, ventilators, and oxygen at the peak of occurrence. This may have been partly caused by emergence of new variant delta. Clinical experience with the cases admitted to hospitals suggested that it is not merely a steep rise in cases but also possibly the case profile is different. This study was taken up to investigate the differentials in the characteristics of the cases admitted in the second wave versus those admitted in the first wave. Records of a total of 14398 cases admitted in the first wave (2020) to our network of hospitals in north India and 5454 cases admitted in the second wave (2021) were retrieved, making it the largest study of this kind in India. Their demographic profile, clinical features, management, and outcome was studied. Age sex distribution of the cases in the second wave was not much different from those admitted in the first wave but the patients with comorbidities and those with greater severity had larger share. Level of inflammatory markers was more adverse. More patients needed oxygen and invasive ventilation. ICU admission rate remained nearly the same. On the positive side, readmissions were lower, and the duration of hospitalization was slightly less. Usage of drugs like remdesivir and IVIG was higher while that of favipiravir and tocilizumab was lower. Steroid and anticoagulant use remained high and almost same during the two waves. More patients had secondary bacterial and fungal infections in Wave 2. Mortality increased by almost 40% in Wave 2, particularly in the younger patients of age less than 45 years. Higher mortality was observed in those admitted in wards, ICU, with or without ventilator support and those who received convalescent plasma. No significant demographic differences in the cases in these two waves, indicates the role of other factors such as delta variant and late admissions in higher severity and more deaths. Comorbidity and higher secondary bacterial and fungal infections may have contributed to increased mortality.

Cross-cultural adaptation of self-reported measures to other languages endeavors to enhance the validity and reliability of the instrument for the local population. Traditionally, qualified academicians or language experts performed the translation task, but nowadays, various online translation tools are available for the same. The present study intends to compare the validity of traditional and online modes of translation of selfreported measures, and to develop a hybrid method by combining the traditional and online methods to achieve an accurate translation cost-effectively. For this purpose, the existing English version of shame and stigma scale was translated into the Hindi language traditionally by language experts, Google translator, and by a hybrid method. The validity of translated versions was tested using the content validity index (CVI). The CVI score was found to be 0.94 for the traditional method, which is significantly higher compared to the online translation method in which the CVI score was 0.42. CVI score in the hybrid method comes to be 0.84. The present study suggests that the online translation method alone is insufficient for the accurate translation of questionnaires and, therefore, it is recommended that hybrid method should be followed for the process of cross-cultural adaptation of self-report measures to impart high accuracy in a cost-effective manner.

Purpose: Long COVID syndrome is now a real and pressing public health concern. We cannot reliably predict who will recover quickly or suffer with mild debilitating long COVID 19 symptoms or battle life threatening complications. In order to address some of these questions, we studied the presence of symptoms and various correlates in COVID 19 patients who were discharged from hospital, 3 months and up to 12 months after acute COVID 19 illness. Methods: This is an observational follow up study of RT PCR confirmed COVID 19 patients admitted at 3 hospitals in north India between April August 2020. Patients were interviewed telephonically using a questionnaire regarding the post COVID symptoms. The first tele calling was done in the month of September 2020, which corresponded to 4 to 16 weeks after disease onset. All those who reported presence of long COVID symptoms, were followed up with a second call, in the month of March 2021, corresponding to around 9 to 12 months after the onset of disease. Results: Of 990 patients who responded to the first call, 615 (62.2%) had mild illness, 227 (22.9%) had moderate and 148 (15.0%) had severe COVID 19 illness at the time of admission. Nearly 40% (399) of these 990 patients reported at least one symptom at that time. Of these 399 long COVID patients, 311 (almost 78%) responded to the second follow up. Nearly 8% reported ongoing symptomatic COVID, lasting 1 to 3 months and 32% patients having post COVID phase with symptoms lasting 3 to 12 months. Nearly 11% patients continued to have at least one symptom even at the time of the second interview (9 to 12 months after the disease onset). Overall, we observed Long COVID in almost 40% of our study group. Incidence of the symptoms in both the follow ups remained almost same across age groups, gender, severity of illness at admission and presence of comorbidity, with no significant association with any of them. Most common symptoms experienced in long COVID phase in our cohort were fatigue, myalgia, neuro psychiatric symptoms like depression, anxiety, brain fog and sleep disorder, and breathlessness. Fatigue was found to be significantly more often reported in the elderly population and in those patients who had a severe COVID 19 illness at the time of admission. Persistence of breathlessness was also reported significantly more often in those who had severe disease at the onset. The overall median duration of long COVID symptoms was 16.9 weeks with inter quartile range of 12.4 to 35.6 weeks. The duration of symptom resolution was not associated with age, gender or comorbidity but was significantly associated with severity of illness at the time of admission (P=0.006). Conclusions: Long COVID is now being recognized as a new disease entity, which includes a constellation of symptoms. Long COVID was in almost 40% of our study group with no correlation to age, gender, comorbidities or to the disease severity. The duration of symptom resolution was significantly associated with severity of illness at the time of admission (P = 0.006). In our study, all patients reported minor symptoms such as fatigue, myalgia, neuro psychiatric symptoms like depression, anxiety, brain fog and sleep disorder and persistence of breathlessness. Severe organ damage was not reported by our subjects. This might be the longest post COVID follow up study on a sample of nearly 1000 cases from India.
