India has the second highest number of cases of sickle cell disease (SCD) and affects the most socioeconomically disadvantaged communities living in a horizontal belt from Gujarat to Odisha state. Despite high prevalence, information about cerebral hemodynamics among children with SCD in India remains scarcely described.We performed transcranial Doppler (TCD) to assess cerebral hemodynamics among Indian children with SCD and evaluated their association with clinical and hematological parameters.Children aged 3-18years, diagnosed with SCD living in Raipur in Chhattisgarh and Ahmedabad in Gujarat state were recruited. TCD was performed to obtain flow velocities from middle cerebral (MCA), intracranial internal carotid (ICA) and basilar artery. Associations were evaluated between timed-average-mean-maximum velocities (TAMMV) and various clinical and hematological parameters.Our prospective study included 62 consecutive children with known SCD. Mean ± SD age of the study population was 9.8 ± 3.9 years and 31 (50%) were male. Mean ± SD hemoglobin was 8.64 ± 1.34 Gm/dL while the mean HbSS ± SD was 70.25 ± 15.27%. While 6 (9.6%) children had suffered from stroke during previous 2 years, 7 (11%) demonstrated abnormal TAMMV. Higher HbSS level along with history of iron chelation therapy, blood transfusion and/or stroke showed a trend towards having higher TAMMV.Stroke and cerebral hemodynamic alterations are common among Indian children with SCD. Larger studies with detailed neuroimaging and genetic evaluations are needed for better understanding, characterization, risk stratification as well as optimization of the timing of blood transfusion to reduce physical disabilities among Indian children with SCD. 相似文献
COVID-19 epidemic has resulted in devastating mortality and morbidity consisting of socioeconomic and health effects that have included respiratory/pulmonary, cardiovascular, mental health and neurological consequences such as anxiety, depression, and substance use. Several effective vaccines have been developed and extensive efforts are underway to develop therapeutics to treat COVID-19. Cannabis and/or its product-cannabidiol (CBD) are being advertised for the treatment of COVID-19 associated mental/neurological complications and substance use disorders. However, research reviewed shows that there is insufficient data from clinical studies to support the use of cannabis or CBD for the treatment of COVID-19 associated mental health and neurological complications. Additional basic and clinical research is suggested to develop cannabis or cannabidiol for the treatment of mental health problems associated with coronavirus infection and or substance use disorders. In the meantime, it is important that the addiction physician/psychiatrist must caution while prescribing or recommending cannabis or CBD for treating such clinical indications.
Graphical abstract
Research shows that currently there is no clinical evidence to support the use of cannabis or any of its compounds including CBD for treating any of the neuropsychiatric complications of COVID-19. Thus, it is important that the addiction physicians/psychiatrists caution their patients from using cannabis or cannabis products for treating any such complications.
Surgical drains are commonly used in plastic surgery. Drains are subsequently removed at arbitrary volumes depending on local protocols. The rational for when to remove a drain has not been scientifically determined. We compared removal of drains at ≤30?ml/24?h vs. ≤50?ml/24?h for 158 wounds, in 90 patients. Postoperative complications, length of hospital stay and resulting cost–benefit were considered. Prospective data were collected for two consecutive similar cohorts of patients undergoing abdominoplasty, bilateral breast reduction and breast augmentation. In the first cohort, drains were removed when drainage was ≤30?ml/24?h and the second cohort when ≤50?ml/24?h. Demographics, days of drainage, surgeon grade and duration of postoperative hospital stay were recorded. Patient records were then analysed and complications recorded, including haematoma, infection, seroma, wound breakdown and fat necrosis. The median postoperative stay for all three operations for both drainage cohorts was similar with no statistically significant difference; however, the drainage time in breast augmentation was significantly less in the <50?ml/24?h group. There were no significant differences in outcome measures between the patients undergoing abdominoplasty, breast reduction or breast augmentation. Drain removal at ≤50 vs. ≤30?ml/24?h did not result in an increase in postoperative morbidity or adverse outcome in any of the three different operation types. 相似文献
The burden of diabetes is expected to rise from 415 million individuals in 2015 to 642 million individuals by 2040. Most individuals pass through a phase of prediabetes before developing full-blown diabetes. Insulin resistance, impaired incretin action, and insulin hypersecretion are central to the pathophysiology of prediabetes. Individuals older than 40 years of age and other high-risk individuals should be screened for diabetes with fasting plasma glucose and/or hemoglobin A1c. For those diagnosed with prediabetes, the goal of treatment should be restoring euglycemia, because there are data showing that restoring normoglycemia during prediabetes and early diabetes can produce lasting remission. The preferred approach for this is intensive lifestyle intervention, which besides reducing progression to diabetes, has also been shown to reduce all-cause mortality in a long-term follow-up study. The best evidence for a pharmacological approach is with metformin. Other drugs that have shown efficacy include thiazolidinediones, alpha-glucosidase inhibitors, orlistat, basal insulin, and valsartan. However, except for metformin, none of these drugs are currently recommended for this purpose. Newer agents such as glucagon-like peptide-1 agonists and dipeptidyl peptidase 4 (DPP-4) inhibitors also have considerable promise in this area. Bariatric surgery can be offered to patients with metabolic syndrome and body mass index of 30-35. 相似文献
