Vaccination saves lives: a real-time study of patients with chronic diseases and severe COVID-19 infection.

OBJECTIVES: This study aims to describe the demographic and clinical profile and ascertain the determinants of outcome among hospitalized coronavirus disease 2019 (COVID-19) adult patients enrolled in the National Clinical Registry for COVID-19 (NCRC). METHODS: NCRC is an on-going data collection platform operational in 42 hospitals across India. Data of hospitalized COVID-19 patients enrolled in NCRC between 1st September 2020 to 26th October 2021 were examined. RESULTS: Analysis of 29 509 hospitalized, adult COVID-19 patients [mean (SD) age: 51.1 (16.2) year; male: 18 752 (63.6%)] showed that 15 678 (53.1%) had at least one comorbidity. Among 25 715 (87.1%) symptomatic patients, fever was the commonest symptom (72.3%) followed by shortness of breath (48.9%) and dry cough (45.5%). In-hospital mortality was 14.5% (n = 3957). Adjusted odds of dying were significantly higher in age group ≥60 years, males, with diabetes, chronic kidney diseases, chronic liver disease, malignancy and tuberculosis, presenting with dyspnoea and neurological symptoms. WHO ordinal scale 4 or above at admission carried the highest odds of dying [5.6 (95% CI: 4.6-7.0)]. Patients receiving one [OR: 0.5 (95% CI: 0.4-0.7)] or two doses of anti-SARS CoV-2 vaccine [OR: 0.4 (95% CI: 0.3-0.7)] were protected from in-hospital mortality. CONCLUSIONS: WHO ordinal scale at admission is the most important independent predictor for in-hospital death in COVID-19 patients. Anti-SARS-CoV2 vaccination provides significant protection against mortality.

Long-term continence disturbance after lateral internal sphincterotomy for chronic anal fissure: a systematic review and meta-analysis.

AIM: A systematic review was carried out to analyse continence at 2 years or more after lateral internal sphincterotomy (LIS) for chronic anal fissure (CAF). METHOD: PubMed, MEDLINE, Scopus, Embase, Ovid, SCI, Cochrane Central Register of Controlled Trials (CENTRAL) and Google Scholar were used to search the literature from 1969-2012 for studies reporting a follow-up of more than 2 years after LIS for CAF. The primary outcome parameter analysed was continence. The secondary outcome parameters included success rate, recurrence, incidence of postoperative abscess and fistula formation and patient satisfaction. RESULTS: Of 324 studies screened, 22 (n = 4512) were included. The mean follow-up period ranged from 24-124 months. The overall continence disturbance rate was 14% (95% CI 0.09-0.2). Weighted analysis showed flatus incontinence in 9% (95% CI 0.04-0.16), soilage/seepage in 6% (95% CI 0.03-0.1), accidental defaecation in 0.91% (95% CI 0.003-0.02), incontinence to liquid stool in 0.67% (95% CI 0.001-0.02) and incontinence to solid stool in 0.83% (95% CI 0.003-0.02) of patients. CONCLUSION: The long-term risk of continence disturbance after lateral internal sphincterotomy is significant. Randomized controlled trials with a long follow-up are needed to substantiate these findings and to redefine its role in the treatment of chronic anal fissure.

The efficacy of anal fistula plug in fistula-in-ano: a systematic review.

AIMS: To assess the efficacy of anal fistula plug (AFP) procedure for the treatment of fistula-in-ano especially the complex fistulas. METHOD: The database of PUBMED, MEDLINE, SCOPUS, EMBASE and COCHRANE LIBRARY for the period 1995-2009 was searched. A systematic analysis was carried to evaluate the success rate of AFP procedure in fistula-in-ano. RESULTS: A total of 25 studies were extracted and 12 (n = 317) were finally included in the systematic review. The follow-up period ranged from 3.5 to 12 months. The AFP procedure had a success rate (patient cure rate) ranging from 24% to 92%. In complex fistula-in-ano in prospective studies (8/12 studies), the success rate was 35-87%. The success rate in patients with Crohn's disease was 29-86%. The success rate in the patients with single tracts was 44-93% and in patients with multiple tracts, success ranged from 20% to 71%. The abscess formation/sepsis rate was 4-29% (11/108) and the plug extrusion rate was 4-41% (42/232-19%). CONCLUSION: Anal fistula plug procedure has a success rate ranging from 24% to 92% in different studies. In prospective studies of complex fistula-in-ano, there was a moderate success rate of 35-87%. As AFP is associated with low morbidity and sepsis, it appears to be a safe procedure. Further randomized controlled trials studying objective parameters of fistula healing are needed to substantiate these findings.

WITHDRAWN: Steroids for treating tuberculous meningitis.

BACKGROUND: Even though corticosteroids have been used alongside antituberculosis drugs for tuberculous meningitis (TBM) since the 1950s their role remains controversial. Some believe corticosteroids improve outcome while others point to the lack of supportive evidence. In patients who are immunocompromised because of HIV infection the risks and benefits of steroids are unknown. OBJECTIVES: To assess the effects of steroids on death and disability in patients with TBM. SEARCH STRATEGY: We searched the Cochrane Infectious Diseases Group specialized trials register (February 2005), The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2005), MEDLINE (1966 to February 2005), EMBASE (1980 to February 2005), and LILACS (February 2005). SELECTION CRITERIA: Randomised controlled trials of steroids in people on TB treatment for TBM. DATA COLLECTION AND ANALYSIS: Two independent reviewers applied study selection criteria, assessed methodological quality and extracted data. MAIN RESULTS: Six trials of 595 patients met the inclusion criteria. No study described allocation concealment. Steroids were associated with fewer deaths (relative risk [RR] 0.79; 95% confidence interval [CI] 0.65 to 0.97) and a reduced incidence of death and severe residual disability (RR 0.58, 95% CI 0.38 to 0.88). Subgroup analysis suggests an effect on mortality in children (RR 0.77, 95% CI 0.62 to 0.96) but the results in a smaller number of adults are inconclusive (RR 0.96, 95% CI 0.50 to 1.84). There is little evidence that the severity of disease influences the effects of steroids on mortality. AUTHORS' CONCLUSIONS: Adjunctive steroids might be of benefit in patients with TBM. However, existing studies are small, and poor allocation concealment and publication bias may account for the positive results found in this review. No data are available on the use of steroids in HIV positive persons. Future placebo-controlled studies should include patients with HIV infection and should be large enough to assess both mortality and disability.

Comparison of the three strategies of verbal scoring of the Glasgow Coma Scale in patients with stroke.

Presence of aphasia in patients with stroke poses a problem in the use of the full form (eye-motor-verbal) Glasgow Coma Scale (GCS). Stroke investigators and clinicians have used three different strategies to deal with the untestable verbal subscale, i.e. eliminating the verbal subscale; pseudoscoring with 'one', and median value substitution; but the predictive accuracy of the strategies has not been compared. To compare the predictive accuracy of the three strategies for acute mortality in stroke, we prospectively applied the GCS to 275 consecutive patients with acute stroke and recorded their survival status before discharge from hospital. 95 (33.8%) patients died. 32 (12%) patients had untestable verbal score. Receiver-Operator-Characteristic curves for predicting mortality were constructed with the GCS sum score and with the multivariate logistic models, and areas under the curves were measured to compare the predictive accuracy. They were all found to be similar (0.87-0.88 sq unit). Specifically, the GCS with eye and motor subscale had 87% accuracy compared to 88% for the model with eye, motor and verbal scale. We conclude that the short-form (eye-motor) GCS is as good a predictor of early mortality (within 2 weeks) as the full form (eye-motor-verbal) GCS in patients with stroke.

Age at marriage and cervical cancer incidence.

Cancer of the uterine cervix is the commonest cancer among Indian women accounting for 1/5 of the total cancer incidence. It is the estimated that by the turn of century 139,000 women in India would be developing cervical cancer. Age at marriage has been recognised as a major risk factor associated with cervical cancer. Over the past 8 decades there has been a rise in age at marriage varying from 14 years in 1901 to 18 years in 1981. Consequently the proportion of women married in the age group 15-19 years has fallen from 88% in 1941 to 45% in 1981. The present paper has attempted to study the effect of change in proportion married below 17 years on cervical cancer incidence for the year 1985 in India. The proportion of married women in the age group 15-19 years was constant around 88% from 1901-41 and from 1951 onwards the reduction in the proportion married has been observed. During the last 35 years, after the start of reduction in the proportion married in the age group (15-19) years, a reduction of 2097 cervical cancer cases or 6.3 percent reduction in the incidence of invasive cervical cancer is observed. It may be postulated that it will take a long time to expect a significant reduction in the incidence of cervical cancer if the primary prevention of rising the age at marriage above 18 years is adopted as a strategy for control of cervical cancer.
