Considerations of the sacroiliac joint (SIJ) and its role in causing lower back and limb pain have taken a secondary role ever since Mixter and Barr's hallmark article in 1934 on the herniated nucleus pulposus. However, recent literature has highlighted the contribution of sacroiliac joint degeneration in the development of failed back surgery syndrome (FBSS), especially in patients undergoing lumbar or lumbosacral spinal fusion surgeries. Many reports have studied the anatomy, physiology, and clinical significance of the sacroiliac joint, but none have linked its dysfunction with other spinal deformities.
 
  A 63-year-old female with a history of multiple complex instrumented spinal fusions presented to our institution with progressive leftward coronal imbalance despite successful arthrodesis from T3 through S1. She was initially treated with decompression and reimplantation, but adjacent segment disease at the SIJ led to laxity, distal failure, and a worsening coronal deformity. A mechanical fall after herly correct the coronal imbalance, reduce pain levels, promote SIJ arthrodesis, and prevent further SIJ-related issues without significant complications over 3 years post-operation.Sleep deficiency is well-documented in individuals with irritable bowel syndrome (IBS). Sleep deficiency includes poor sleep quality and an inadequate amount of sleep, and is a modifiable risk factor for IBS symptom exacerbations. Prior studies in other populations have identified chronotype and social jetlag (SJL) as important determinants of sleep outcomes. However, chronotype and SJL have not been examined in women with IBS. We used multiple linear regression analyses to determine whether chronotype and SJL are associated with sleep outcomes during weekdays among women with IBS predominant constipation (IBS-C), IBS with predominant diarrhea (IBS-D), and healthy control (HC) women. This sample included 62 women with IBS (IBS-C = 29, IBS-D = 33) and 58 HC women who completed a 28-day daily diary from two study cohorts. The average age of the participants was 30.1 (SD 7.2) years. Chronotype was estimated from daily diary data with the average mid-sleep time on weekends (MSWwe). SJL was calculated by subtracting the average mid-sleep time on weekdays from MSWwe. Sleep outcomes included diary assessments of sleep quality, sleep need met, and restorative sleep during weekdays. In HCs, later chronotype was predictive of lower sleep quality (β = -0.19, p .05). Compared to HCs, the relationships of chronotype with weekday sleep outcomes in the women with IBS-D were in the opposite directions (all p less then .05). This exploratory study suggests that chronotype expression may reflect the temporal associations of sleep outcomes within IBS bowel pattern predominance subgroups, particularly sleep quality and sleep need met. Additional investigations are warranted to examine whether specific temporal attributes of symptoms and/or symptom severity associated with IBS subgroups contribute to chronotype expression.ABSRACT1. An experiment was designed to compare the effects of supplementing laying hen diets with phytase and myo-inositol (inositol).2. Five diets were formulated high balanced protein (HBP - 840 mg of Dlys/hen/day), HBP with inositol (HBP+I - 0.16%), reduced balance protein (RBP - 672 mg of Dlys/hen/day), RBP with inositol (RBP+I - 0.16%) and RBP with phytase (RBP+P - 3000 FTU/kg).3. Laying hen production, inositol concentrations, digestive tract morphology, amino acid digestibility and intestinal inositol transporters transcript abundance were evaluated. Data were analysed with a one-way ANOVA in SAS 9.4. Contrasts were used to assess the effect of protein, inositol, phytase and phytase vs. inositol. Differences were accepted when P ≤ 0.05.4. No effect on hen-day egg production or feed efficiency was found.  https://www.selleckchem.com/products/bms-927711.html  However, feed intake and the incidence of abnormally shaped eggs were 0.77 g/h/d and 0.17% higher, respectively, in inositol treatments. Inositol decreased egg specific gravity from 1.088 to 1.0865.5. Inositol concentration in egg yolk was similar among HBP+I, RBP+I and RBP+P, and higher than for the HBP and RBP diet groups. Both gizzard and ileal digesta were enriched in inositol in all supplemented treatments, and phytase supplementation decreased the level of IP5 and IP6 in the gizzard and ileum. Generally, neither phytase or inositol affected amino acid digestibility.6. Inositol increased transcript abundance of alkaline phosphatase in the ileum, while phytase upregulated duodenal alkaline phosphatase and SMIT1, jejunal SMIT2 and reduced ileal HMIT and SMIT1 abundance.7. In conclusion, no effect of phytase or inositol was found for laying hen production performance or amino acid digestibility, but egg quality was reduced by inositol supplementation. Inositol concentration in egg yolk was similar among supplemented treatments.Medicinal plants are sources of natural antioxidants thanks to their secondary metabolites. Previous studies showed that administration of Erodium glaucophyllum (EG) (Geraniaceae family) was found to alleviate the deleterious effects of obesity-induced damage on liver, heart and kidney. This study, carried out on adult male Wistar rats, evaluates the inhibitory effects of supplementation with E. glaucophyllum extract on obesity. Under our experimental conditions, administration of Erodium aqueous extract decreased the total cholesterol, LDL-cholesterol, and triglycerides levels as well as ASAT, ALAT, LDH, PAL levels and TBARS concentration; and increased the (HDL) with the antioxidant enzymes (SOD, CAT, GPx) in liver, heart and kidney, compared to HFD group. The anti-obesity effects of the Erodium extract in several organs were mainly due to the interaction of these bioactive molecules (polyphenols, flavonoids, and tannin compounds) and the enzyme system which could be determined by phytochemical analysis.The 2019 coronavirus pandemic (COVID-19) has affected all of society at different levels. Similarly, COVID-19 has significantly impacted every medical field, including neurosurgery. By exposing scarcities in the healthcare industry and requiring the reallocation of available resources towards the priority setting and away from elective surgeries and outpatient visits, the pandemic posed new, unprecedented challenges to the medical community. Despite the redistribution of resources towards COVID-19 patients and away from elective surgeries, urgent and emergent surgeries for life-threatening conditions needed to be continued. The neurosurgical community, like other specialties not directly involved in the care of COVID-19 patients, initially struggled to balance the needs of COVID-19 patients with those of neurosurgical patients, residents, and researchers. Several articles describing the effect of COVID-19 on neurosurgical practice and training have been published throughout the COVID-19 pandemic. This article aims to provide a focused review of the impact COVID-19 has had on neurosurgical practice and training as well as describe neurological manifestations of the disease.
