Obesity is an established risk factor for the development of acute ischemic stroke. However, its effect on clinical outcomes after acute ischemic stroke has remained controversial. In the present study, we evaluated the association of body mass index (BMI) on outcomes after mechanical thrombectomy (MT) for large vessel occlusion acute ischemic stroke (LVOS).

We reviewed our prospective endovascular database for patients who had undergone MT for LVOS from 2015 to 2018. The BMI was analyzed as a continuous and categorical variable, with the latter defined as BMI, <18.5 kg/m
(underweight); BMI, 18.5-24.9 kg/m
(normal); BMI, 25-29.9 kg/m
(overweight), and BMI, >30 kg/m
(obese). find more Multivariate analysis was used to determine the outcome predictors.

A total of 335 patients had undergone MT, with 7 (2.1%) classified as underweight, 107 (31.9%) normal, 141 (42.1%) overweight, and 80 (23.9%) obese. The procedural times, techniques, and reperfusion success (treatment in cerebral infarction score >2bnal independence in recanalized patients. Thus, the obesity paradox does not appear to pertain to MT, although larger prospective studies are necessary.
The true incidence of perioperative coronavirus disease 2019 (COVID-19) has not been well elucidated in neurosurgical studies. We reviewed the effects of the pandemic on the neurosurgical case volume to study the incidence of COVID-19 in patients undergoing these procedures during the perioperative period and compared the characteristics and outcomes of this group to those of patients without COVID-19.

The neurosurgical and neurointerventional procedures at 2 tertiary care centers during the pandemic were reviewed. The case volume, type, and acuity were compared to those during the same period in 2019. The perioperative COVID-19 tests and results were evaluated to obtain the incidence. The baseline characteristics, including a modified Medically Necessary Time Sensitive (mMeNTS) score, and outcome measures were compared between those with and without COVID-19.

A total of 405 cases were reviewed, and a significant decrease was found in total spine, cervical spine, lumbar spine, and functional/pain cases. No significant differences were found in the number of cranial or neurointerventional cases. Of the 334 patients tested, 18 (5.4%) had tested positive for COVID-19. Five of these patients were diagnosed postoperatively. The mMeNTS score, complications, and case acuity were significantly different between the patients with and without COVID-19.

A small, but real, risk exists of perioperative COVID-19 in neurosurgical patients, and those patients have tended to have a greater complication rate. Use of the mMeNTS score might play a role in decision making for scheduling elective cases. Further studies are warranted to develop risk stratification and validate the incidence.

These technologies, collectively called omics, have been widely applied in the last 2 decades to study biological systems to gain deeper insight into mechanisms driving the physiology and pathophysiology of human health and disease. Because of its complex, multifactorial nature, food allergy is especially well suited to be investigated using omics approaches. In this rostrum, we review how omic technologies have been applied to explore diverse aspects of food allergy, including adaptive and innate immune processes in food-allergic responses, the role of the microbiome in food allergy risk, metabolic changes in the gut and blood associated with food allergy, and the identification of biomarkers and potential therapeutic targets for the condition. We discuss the strengths and limitations of the studies performed thus far and the need to adopt systems biology approaches that integrate data from multiple omics to fully leverage the potential of these technologies to advance food allergy research and care.The whitefly Bemisia tabaci is an agricultural pest causing large economic losses worldwide. We analysed the genomic sequence of a new viral member of the family Dicistroviridae identified by high-throughput sequencing of total RNA extracted from whiteflies. The virus, tentatively named Bemisia-associated dicistrovirus 2 (BaDV-2), has a genome of 8012 nucleotides with a polyadenylated 3' end. In contrast to typical dicistroviruses, BaDV-2 has a genome containing three open reading frames (ORFs) encoding predicted proteins of 1078 (ORF1a), 481 (ORF1b) and 834 (ORF2) amino acids, which correspond to replicase A (containing helicase and cysteine protease domains), replicase B (a domain of an RNA-dependent RNA polymerase - RdRP) and capsid proteins, respectively. The 3' end of ORF1a contains a potential frameshift signal, suggesting that ORF1a and ORF1b may be expressed as a single polyprotein (replicaseFS), corresponding to other dicistroviruses. The BaDV-2 genomic sequence shares the highest nucleotide identity (61.1 %) with Bemisia-associated dicistrovirus 1 (BaDV-1), another dicistrovirus identified from whiteflies. The full BaDV-2 replicaseFS polyprotein clustered with aparaviruses, whereas the capsid polyprotein clustered with cripaviruses in phylogenetic analyses, as with BaDV-1. The intergenic region (IGR) between ORF1b and ORF2 is predicted to adopt a secondary structure with atypical features that resembles the dicistrovirus IGR IRES structure. Our analyses indicate that BaDV-2 is a novel dicistrovirus and that BaDV-2 together with BaDV-1 may not be appropriately grouped in any of the three currently accepted dicistrovirus genera.
