RESUMEN
BACKGROUND: Intracerebral hemorrhage (ICH) is associated with high mortality, morbidity, and recurrence. Studies have reported the accuracy of several blood biomarkers in predicting clinical outcomes; however, their independent contribution in prediction remains to be established. AIM: To investigate the incremental accuracy in predicting clinical outcomes in patients with ICH in a north Indian population using blood-based biomarkers. METHODS: In this study, a total of 250 ICH cases were recruited within 72 hours of onset. Baseline clinical and CT scan measurement were recorded. Homocysteine (HCY), C-reactive protein (CRP), matrix metalloproteinase-9 (MMP9), E-selectin (SELE), and P-selectin (SELP) levels were measured through ELISA. Telephonic follow-up was done by using mRS scale at three months. RESULTS: The mean age of cohort was 54.9 (SD±12.8) years with 64.8% patients being male. A total of 109 (43.6%) deaths were observed over three months follow-up. Area under the receiver operating characteristics curve-(AUROC) for 90-day mortality were 0.55 (HCY), 0.62 (CRP), 0.57 (MMP9), 0.60 (SELE) and 0.53 (SELP) and for poor outcome at 90-day (mRS: 3-6) were 0.60 (HCY), 0.62 (CRP), 0.54 (MMP9), 0.67 (SELE) and 0.54 (SELP). In multivariable model including age, ICH volume, IVH and GCS at admission, serum SELE (p=0.004) significant for poor outcome with improved AUROC (0.86) and HCY (p=0.04), CRP (p=0.003) & MMP9 (p=0.02) for mortality with least Akaike's Information Criterion-(AIC) (1060.5). CONCLUSIONS: Our findings suggest that the serum SELE is a significant predictor of poor outcome and HCY, CRP & MMP9 for Mortality in patients with ICH in the north Indian population.

For any nation the health of its citizens especially that of the reproductive age women is critical and of paramount importance as they are the ones who usher in the new generation. Now that India is undergoing triple burden of malnutrition, if the pregnant woman is underweight, overweight, obese or diabetic both the mother and the baby are at a high risk of developing complications not only during pregnancy but also postpartum. Hence, having a good nutritional status is so important even before the woman conceives.
RESUMEN
Epilepsy is one of the common neurological diseases which affects 65-70 million people worldwide. Modified Atkins diet (MAD) as a therapy is used as one of the treatments to reduce the seizures occurrence in epileptic patients. The purpose of this purpose is to review all evidence regarding the efficacy of the MAD from randomized controlled trials (RCTs) in adolescents and adults with drug resistant epilepsy (DRE). The total of three databases were searched (PubMed, Embase, and Cochrane Library) till 31 January 2023. Only RCTs with MAD as a one of the treatment arms were included in meta-analysis. The proportion of reduction of seizures in patients with epilepsy and relative risk to identify the relationship between MAD (as risk) to decrease the epileptic seizure was used as outcomes. The Jadad score with three domains was used to estimate the quality of RCTs included for meta-analysis. Only three RCTs were included following the stringent inclusion criteria in current meta-analysis. The pooled proportion from 142 patients going through MAD therapy shows the reduction in epileptic seizure ≥50%, by the random effect model was 0.23 (95% confidence interval [CI], 0.10 to 0.37). Our meta-analysis underlines a significant efficacy of MAD compared to the control group in seizure reduction ≥50%, The pooled relative risk was 6.47 (95% CI, 1.60 to 26.14; p-value <0.05). MAD therapy was efficacious and had better compliance for seizure reduction in subjects with DRE.
RESUMEN
Despite consensus on universal screening of women at 24-28 weeks for a diagnosis of gestational diabetes, controversy remains on an appropriate criterion. The study is aimed to find out the sensitivity and specificity of Diabetes in Pregnancy Study Group India (DIPSI) criteria compared to the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria for diagnosis of Gestational Diabetes Mellitus (GDM). A meta-analysis of studies comparing DIPSI as an index test to IADPSG as the reference test for diagnosing GDM was carried out. A total of 8 comparative studies were included. Pooled analysis showed a sensitivity of 0.44 [0.29 to 0.60] and specificity of 0.97 [0.94 to 0.98], which means the index test DIPSI will correctly identify only 44% of the subjects who have the disease (GDM positive) but it will also fail to identify 56% of the GDM positive subjects. Derek's funnel graph revealed fewerchances of publication bias. Though convenient, DIPSI criteria was not found to be sensitive enough for a diagnosis of GDM and missed an opportunity to improve pregnancy and subsequent long-term outcomes for a substantial number of women. Further studies should focus on comparing pregnancy outcomes for the two criteria, so that decision to adopt any criteria is more evidence-based.

Preoperative ultrasound assessment of inferior vena cava (IVC) diameter and the collapsi-bility index might identify patients with intravascular volume depletion. The purpose of this review was to gather the existing evidence to find out whether preoperative IVC ultrasound (IVCUS) derived parameters can reliably predict hypotension after spinal or general anaesthesia. PubMed was searched to identify research articles that addressed the role of IVC ultrasound in predicting hypotension after spinal and general anaesthesia in adult patients. We included 4 randomized control trials and 17 observational studies in our final review. Among these, 15 studies involved spinal anaesthesia and 6 studies involved general anaesthesia. Heterogeneity with respect to the patient populations under evaluation, definitions used for hypotension after anaesthesia, IVCUS assessment methods, and cut-off values for IVCUS-derived parameters to predict hypotension precluded pooled meta-analysis. The maximum and minimum reported sensitivity of the IVC collapsibility index (IVCCI) for predicting post-spinal hypotension was 84.6% and 58.8% respectively, while the maximum and minimum specificities were 93.1% and 23.5% respectively. For the prediction of hypotension after general anaesthesia induction, the reported ranges of sensitivity and specificity of IVCCI were 86.67% to 45.5% and 94.29% to 77.27%, respectively. Current literature on the predictive role of IVCUS for hypotension after anaesthesia is heterogeneous both in methodology and in results. Standardization of the definition of hypotension under anaesthesia, method of IVCUS assessment, and the cut-offs for IVC diameter and the collapsibility index for prediction of hypotension after anaesthesia are necessary for drawing clinically relevant conclusions.

BACKGROUND AND AIMS: The diagnosis of Gestational diabetes mellitus (GDM) is challenging and controversial due to the heterogeneity or lack of consensus regarding the screening and diagnostic criteria for GDM. METHODS: A meta-analysis of studies comparing Diabetes in Pregnancy Study Group India (DIPSI) and WHO 1999 for diagnosing GDM was carried out. RESULTS: A total of 6 comparative studies were included. Pooled analysis showed sensitivity and specificity as 0.79 (95% CI: 0.53 to 0.92) and 0.97 (95% CI: 0.94 to 0.98) respectively. CONCLUSION: Based on the results of the meta-analysis, DIPSI showed higher specificity when compared to WHO 1999, hence may be used to rule in disease in probable GDM cases. However, the results should be interpreted more cautiously and carefully since only a few studies were included.

BACKGROUND: After acute ischemic stroke, a higher level of troponin has been considered as an important biomarker for predicting mortality. AIM AND OBJECTIVES: The study aimed to quantitatively assess the prognostic significance of the effect of baseline troponin levels on all-cause mortality in patients with acute ischemic stroke using a meta-analysis approach. MATERIALS AND METHODS: The following electronic databases such as PubMed, Web of Science, Cochrane Central Register of Controlled Trials, TRIP Database, and ClinicalTrialsgov were used for obtaining the relevant articles from literature. Data were extracted in standardized data collection form by two independent investigators. Any disagreements were resolved by consensus. All the statistical analyses were performed in STATA software (Version 13.1). RESULTS: A total of 19 studies were included in the present meta-analysis involving a total of 10,519 patients. The pooled analysis suggested that elevated serum troponin level was associated with inhospital mortality (rate ratios [RR] 2.34, 95% confidence interval [CI] 1.30-3.38) and at the end of last follow-up mortality (RR 2.01; 95% CI 1.62-2.40). Sensitivity analysis by removing a single study by turns indicated that there was no obvious impact of any individual study on the pooled risk estimate. No significant publication bias was observed in the beg test (P = 0.39); however, significant publication bias was observed in the egger test (P = 0.046). CONCLUSION: Our findings indicated that a higher level of troponin might be an important prognostic biomarker for all cause in hospital and follow-up mortalities in patients with acute ischemic stroke. These study findings offer insight into further investigation in prospective studies to validate this particular association. The study was registered in OSF registries DOI's 10.17605/OSF. IO/D95GN.
RESUMEN
BACKGROUND AND OBJECTIVE: Stem cell therapy has emerged as a potential therapy for the treatment of stroke. We performed a systematic review and meta-analysis of published randomized controlled studies using various types of stem cell therapies in patients with ischemic stroke (IS). METHOD: Literature search was carried out using PubMed, Google Scholar, Cochrane library, and clinicaltrial.gov to identify studies on stem cell therapy in IS from its inception till January 2020. Data were extracted independently by two reviewers. STATA version 13 was used for carrying out meta- analysis. We included only randomized controlled trials (RCTs) if any of the stem cell therapy was used to treat patients with IS in any phase after the index stroke. RESULTS: We included a total of eight randomized controlled studies involving 459 subjects (217 intervention and 242 controls) in the meta-analysis. We did not observe statistically significant reduction in mean NIHSS score in the intervention group (SMD - 0.34, 95% CI - 0.76 to 0.08) in patients with acute or sub-acute stroke. However, a statistically significant reduction (SMD - 1.57, 95% CI -2.22 to -0.92) was observed in patients with chronic ischemic stroke. Statistically non-significant reduction in mean mRS in the intervention group (SMD 0.04, 95% CI -0.20 to 0.28) in patients with acute or sub-acute ischemic stroke was observed, however a statistically significant reduction (SMD - 1.07, 95% CI - 1.94 to -0.19) was noted in patients with chronic stroke. We did not observe statistically significant reduction in mean Barthel index score (SMD 0.24, 95%CI -1.69 to 2.17) in chronic stroke. Statistically non-significant lower mortality rate was observed in intervention group compared to controls (Risk Ratio 0.84, 95% CI 0.43 to 1.66) among acute or sub-acute, as well as in the chronic stroke group (Risk Ratio 0.47, 95% CI 0.20 to 1.09). CONCLUSION: Our meta-analysis provides no clinically important evidence for efficacy of stem cells in reducing neurological deficit compared to control group. Well-designed large randomized controlled trials are required to provide more information on the efficacy of stem cell therapy in patients with IS.
RESUMEN
BACKGROUND AND AIMS: The entire globe is undergoing an unprecedented challenge of COVID-19 which has affected the lifestyle behaviour of individuals. The present review is an attempt to summarize the effect of pandemic COVID-19 on lifestyle behaviour among the Indian population. METHODS: A review was carried out to summarize the effect of pandemic COVID-19 on lifestyle behaviour focusing on changes in dietary or eating behaviour, stress, sleep pattern, and level of physical activity among the Indian population. Literature searches were conducted in PubMed and Google Scholar from inception till October 2020 to identify all relevant studies. RESULTS: A total of 11 studies (n = 5957, age group 18-70 years, comprising both genders) consisting of 1 hospital and 10 community based, were included in the present review. A change in lifestyle behaviour was observed due to COVID-19. Psychosocial or any kind of mental stress among the participants was found to be prevalent. Weight gain and decline in physical activity were also observed. Not only sleep quantity but sleep quality was also found to be affected due to COVID-19. CONCLUSION: The present review indicates the need for lifestyle behaviour programmes via using the platform of E-media and also for the dissemination of health education.

BACKGROUND AND AIMS: Vitamin C has been used as an anti-oxidant in various diseases including viral illnesses like coronavirus disease (COVID-19). METHODS: Meta-analysis of randomized controlled trials (RCT) investigating the role of vitamin C supplementation in COVID-19 was carried out. RESULTS: Total 6 RCTs including n = 572 patients were included. Vitamin C treatment didn't reduce mortality (RR 0.73, 95% CI 0.42 to 1.27; I2 = 0%; P = 0.27), ICU length of stay [SMD 0.29, 95% CI -0.05 to 0.63; I2 = 0%; P = 0.09), hospital length of stay (SMD -0.23, 95% CI -1.04 to 0.58; I2 = 92%; P = 0.57) and need for invasive mechanical ventilation (Risk Ratio 0.93, 95% CI 0.61 to 1.44; I2 = 0%; P = 0.76). Further sub-group analysis based on severity of illness (severe vs. non-severe), route of administration (IV vs. oral) and dose (high vs. low) failed to show any observable benefits. CONCLUSION: No significant benefit noted with vitamin C administration in COVID-19. Well-designed RCTs with standardized control group needed on this aspect.

BACKGROUND: Vitamin-D is an immune-modulator which might be linked to disease severity by SARS-CoV-2. METHODS: Meta-analysis of RCTs and quasi-experimental studies, evaluating the role of vitamin-D supplementation in COVID patients was done. RESULTS: Total 5 studies (3 RCTs and 2 Quasi-experimental) including n = 467 patients were included. Vitamin D didn't reduce mortality (RR 0.55, 95%CI 0.22 to 1.39, p = 0.21), ICU admission rates (RR 0.20, 95% CI 0.01-4.26, p = 0.3) and need for invasive ventilation (RR 0.24, 95% CI 0.01-7.89, p = 0.42). CONCLUSION: No significant difference with vitamin-D supplementation on major health related outcomes in COVID-19. Well-designed RCTs are required addressing this topic.

BACKGROUND: Serum leptin has been considered as an important measurable diagnostic and prognostic biomarker for polycystic ovarian syndrome (PCOS), although its evidence for use in clinical practice is limited. We aim to synthesize the available evidence on the clinical use of serum leptin values in PCOS by doing a systematic review and meta-analysis of studies. OBJECTIVE: To conduct a meta-analysis to determine the pooled effect size of the association of leptin levels in patients with PCOS. METHODS: We searched electronic databases, i.e., PubMed, Google Scholar, Web of Science, ClinicalTrials.gov, and Medline from inception to September 2020, keeping filters for human studies and published in the English language. We used the random-effects model if heterogeneity between the studies was > 50%; otherwise, a fixed-effect model was applied to determine the standardized mean difference with 95% CI for comparison of leptin level between cases and controls. All the statistical analyses were completed using software STATA version 13. RESULTS: The meta-analysis included a total of 35 studies involving 2015 cases and 1767 controls that suggested statistically significantly higher leptin levels in the women with PCOS as compared to controls (SMD, 1.76, 95% CI 1.28 to 2.23, P < 0.001). In the stratified analysis when only high methodological quality studies were included, we did not observe a statistically significant difference in the leptin level between PCOS and controls (SMD 0.68, 95% CI -0.09 to 1.46). Analysis restricted to low methodological quality studies observed statistically significant high leptin levels in PCOS women as compared to controls (SMD 2.24, 95% CI 1.65 to 2.83). CONCLUSION: The available evidence suggests that elevated leptin levels may be associated with risk of PCOS as compared to controls; however, failure to observe the similar association in high methodological quality studies demands further well-designed adequately powered studies to validate the findings.
