Perioperative Management in Reverse Total Neck Arthroplasty.
These technologies put together are termed as "Indigenous Technical Knowledge" (ITKs) and these ITKs have helped them a lot for sustainable agriculture in the region. Among different ITKs bunding of field, plowing before monsoon, filter strips, earthing-up in maize, mulching, compression of soil in sugarcane are the important ones for restoring the fertility of soils, reducing erosion losses, improving land productivity, and ultimately livelihoods in the region.
Currently, the risk factors for subsequent fracture following vertebral augmentation remain incomplete and controversial. To provide clinicians with accurate information for developing a preventive strategy, we carried out a comprehensive evaluation of previously controversial and unexplored risk factors.

We retrospectively reviewed patients with osteoporotic vertebral compression fracture in lumbar spine who received vertebral augmentation between January 2019 and December 2020. Based on whether refracture occurred, patients were assigned to refracture and non-refracture group. The clinical characteristics, imaging parameters (severity of vertebral compression, spinal sagittal alignment, degeneration of paraspinal muscles), and surgical indicators (cement distribution and leakage, correction of spinal sagittal alignment) were collected and analyzed.

There were 128 patients and 16 patients in non-refracture and refracture group. The incidence of previous fracture, multiple fractures, and cement leakage as independent risk factors. Furthermore, the correction of BA should not exceed 3.45°, especially in patients with risk factors.
To evaluate the relations of dietary total antioxidant capacity (DTAC) with mortality outcomes in a Chinese population.

The study included 62,063 participants from the Singapore Chinese Health Study. The participants were 45-74years at baseline (1993-1998) when dietary data were collected with a validated 165-item food frequency questionnaire. The DTAC was derived using two widely adopted scores of integrated dietary consumption of antioxidant nutrients, i.e., the Comprehensive Dietary Antioxidant Index (CDAI) and Vitamin C Equivalent Antioxidant Capacity (VCEAC). We used Cox proportional hazard model to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations with adjustment for potential confounders.

During 1,212,318 person-years of follow-up, 23,397 deaths [cardiovascular diseases (CVD) 7523; respiratory diseases 4696; and cancer 7713] occurred. In multivariable models, the HR (95% CI) comparing participants in the highest vs. lowest quartile of CDAI was 0.85 (0.82, 0.88) for all-cause mortality, 0.82 (0.76, 0.88) for CVD mortality, 0.76 (0.70, 0.83) for respiratory disease mortality (all P-trend < 0.001), and 0.94 (0.88, 1.00) for cancer mortality (P-trend = 0.16). Similar associations were found with the VCEAC index. Higher intakes of the DTAC components, i.e., vitamin C, vitamin E, carotenoids, and flavonoids, were all associated with lower mortality risk.

Diet with a higher antioxidant capacity in midlife was associated with a lower risk of all-cause, cardiovascular and respiratory disease mortality in the Singapore Chinese population, supporting the public health recommendation of consuming more plant-based foods that are rich in antioxidant nutrients.

Oral administration of Oxalobacter formigenes (O. formigenes), an oxalate-degrading bacterium, is thought to derive oxalate from systemic sources by inducing net enteric oxalate secretion. Here, the impact of O. formigenes on nephrocalcinosis was investigated in an ethylene glycol rat model mimicking hepatic oxalate overproduction in primary hyperoxaluria. Eighteen rats were administered ethylene glycol (0.75% in drinking water) for 6 weeks, of which 9 were treated by oral gavage with O. formigenes and 9 received vehicle. Five control rats did not receive ethylene glycol or O. formigenes. Plasma and urinary oxalate levels, calcium oxalate crystalluria, urinary volume, fluid intake, and serum creatinine were monitored during the study. On killing, nephrocalcinosis was quantified. Ethylene glycol intake induced pronounced hyperoxalemia, hyperoxaluria, calcium oxalate crystalluria and nephrocalcinosis. Concomitant O. formigenes treatment partially prevented the ethylene glycol-induced increase in plasma oxalate and completely prevented nephrocalcinosis. Urinary oxalate excretion was not reduced by O. formigenes treatment. Nevertheless, absence of crystals in renal tissue of O. formigenes-treated ethylene glycol animals indicates that the propensity for oxalate to crystallize in the kidneys was reduced compared to non-treated animals. This is supported by the lower plasma oxalate concentrations in O. formigenes-treated animals. This study shows a beneficial effect of O. formigenes treatment on ethylene glycol-induced hyperoxalemia and nephrocalcinosis, and thus supports a possible beneficial effect of O. formigenes in primary hyperoxaluria.Three-dimensional (3D) printed anatomical models can provide cognitive anatomical information. click here We aimed to study the effect of a 3D printed kidney model on patient understanding of kidney anatomy and the percutaneous nephrolithotomy (PCNL) procedure as well as the overall patient satisfaction with the model. Seven patients who underwent PCNL were enrolled in the study. Personalized 3D printed kidney models were constructed based on the patients' computed tomography images. Patients completed two questionnaires regarding their understanding and satisfaction with the use of the 3D printed kidney model before and after using the model during informed consent. The mean age of the study population was 58.0 years. Comparison of patient understanding and satisfaction between the two questionnaires showed a general trend toward better understanding and improved satisfaction with use of 3D printed kidney models. Statistically significant results were seen for understanding of kidney anatomy, stone size, procedure, and satisfaction (p values 0.046, 0.025, 0.046, and 0.046, respectively). Five of the seven patients (71.4%) answered that the model was very useful. However, none of the patients answered that the cost was appropriate. In the current study, patients showed improved understanding of the kidney anatomy and the PCNL procedure and higher satisfaction with using the 3D printed kidney model during informed consent. With further studies using larger patient numbers and decreased production cost, using 3D printed kidney models has the potential to be a useful adjunct for patient understanding during PCNL.The efficacy and safety of extracorporeal shock wave therapy (ESWT) on chronic plantar fasciitis (PF) in patients with axial spondyloarthritis (axSpA) remain unclear. To investigate the efficacy and tolerability of ESWT in patients with PF in axSpA. In this double-blind, randomized controlled trial, 22 axSpA patients with PF who had heel pain above 5 according to visual analog scale (VAS) over 3 months were randomly divided into 2 groups ESWT and sham-ESWT. Both groups received a total of three treatments at 1-week intervals. All patients were assessed by the VAS, heel pressure algometry, Foot Function Index (FFI), and plantar fascia ultrasonography (thickness and morphology) at baseline, 1 week after each session, 4th and 8th week after the last therapy. The mean ± SD ages of the ESWT and sham-ESWT groups were 43.8 ± 8.2 and 48.5 ± 7.6 years, respectively. Significant time effects between the time points were observed in both groups in terms of VAS, pressure algometry, and FFI. There was a statistically significant decrease in pain, an increase in perceived pressure algometry values, and an improvement in activity restriction in the ESWT group compared to the sham-ESWT group. There was not a change in the plantar fascia thickness before and after the intervention in both groups. No side effects were observed during the treatment and follow-up. ESWT appears to be a safe and well-tolerated physical therapy modality for improving chronic refractory heel pain due to PF in patients with axSPA. This trial was registered to The Australian New Zealand clinical trial with the registration number ACTRN12618001954213. The enrollment began in 15/12/2018 and data collection stopped in 29/05/2020.Soft-tissue lumps and bumps are a common referral for imaging in children and adolescents. The etiology of these lesions includes benign non-tumorous lesions, as well as benign and malignant tumors. Some of these lesions have a characteristic imaging appearance but others do not and require tissue sampling to make a diagnosis. MRI typically provides the best overall characterization of soft-tissue masses; however, in some cases US provides complementary information to that provided by MRI that can help make a diagnosis.Muscle spindle afferent feedback is modulated during different phases of locomotor tasks in a way that facilitates task goals. However, only a few studies have studied H-reflex modulation during landing. This study aimed to characterize soleus (SOL) H-reflex modulation during the flight and early landing period of drop landings. Since landing presumably involves a massive increase in spindle afferent firing due to rapid SOL muscle stretching, we hypothesized H-reflex size would decrease near landing reflecting neural modulation to prevent excessive motoneuron excitation. The soleus H-reflex was recorded during drop landings from a 30 cm height in nine healthy adults. Electromyography (SOL, tibialis anterior (TA), medial gastrocnemius, and vastus lateralis), ankle and knee joint motion and ground reaction force were recorded during landings. Tibial nerve stimulation was timed to elicit H-reflexes during the flight and early ground contact period (five 30 ms Bins from 90 ms before to 60 ms after landing). The H-reflexes recorded after landing (0-30 and 30-60 ms) were significantly smaller (21-36% less) than that recorded during the flight periods (90-0 ms before ground contact; P ≤ 0.004). The decrease in H-reflex size not occurring until after ground contact indicates a time-critical modulation of reflex gain during the last 30 ms of flight (i.e., time of tibial nerve stimulation). H-reflex size reduction after ground contact supports a probable neural strategy to prevent excessive reflex-mediated muscle activation and thereby facilitates appropriate musculotendon and joint stiffness.
The aim of this study was to examine the effects of proinflammatory cytokines on cells of different developmental stages during the generation of stem cell-derived beta cells (SC-beta cells) from human pluripotent stem cells (hPSCs). We wanted to find out to what extent human SC-beta cells are suitable as an experimental cellular model and, with regard to a possible therapeutic use, whether SC-beta cells have a comparable vulnerability to cytokines as bona fide beta cells.

hPSCs were differentiated towards pancreatic organoids (SC-organoids) using a 3D production protocol. SC-beta cells and non-insulin-producing cells were separated by FACS and differential gene expression profiles of purified human SC-beta cells, progenitor stages and the human beta cell line EndoC-βH1, as a reference, were determined after 24h incubation with the proinflammatory cytokines IL-1β, TNF-α and IFN-γ via a transcriptome microarray. Furthermore, we investigated apoptosis based on caspase cleavage, the generation of reactive oxygen species and activation of mitogen-activated protein-kinase (MAPK) stress-signalling pathways.
