Objective: Chronic subdural hematoma (CSDH) is a common form of intracranial hemorrhage with a substantial recurrence rate. We aimed to investigate the predictive factors for the postsurgical recurrence of CSDH.
Methods: We retrospectively reviewed the medical records of patients with CSDH who underwent surgery in West China Hospital between January 2012 and June 2018. Univariate and multivariate analyses were performed to identify the relationships between recurrence of CSDH and factors such as age, sex, history of injury, Markwalder grading, computed tomography findings, surgical methods, and outcomes.
Results: A total of 328 patients (281 men and 47 women) aged 22-93 years (mean age, 65.14 ± 13.76 years) were included. Computed tomography findings at admission showed mixed density hematoma in 136 patients, isodensity hematoma in 140, high-density hematoma in 34, and low-density hematoma in 18. The mortality and recurrence rate were 0.30% (1 of 328) and 2.44% (8 of 328), respectively. Six months postoperatively, 327 patients had Markwalder grade 0. Hematoma recurred in 8 patients of which 7 were mixed density hematoma and 1 was isodensity hematoma. Six patients who underwent craniotomy had thickened inner neomembrane that was resected. Univariate and multivariate analyses found mixed density hematoma to be an independent risk factor for the recurrence of CSDH.
Conclusions: Burr hole craniostomy with irrigation and closed-system drainage is effective for the surgical treatment of CSDH. Mixed density hematoma is an independent predictor for the recurrence of CSDH. Presence of thick inner neomembrane might be the primary cause of CSDH recurrence.

Fast growth rate and stocking density are global animal welfare concerns for broiler chickens. The objective of this study was to evaluate the effect of genetic strain and stocking density on the behavior of broilers. In a 2 × 2 randomized complete block design, conventional (CONV) and slow-growing (SG) broilers were stocked at either 29 kg/m (LO, n = 31 birds/pen) or 37 kg/m (HI, n = 40 birds/pen) in 16 pens (n = 4 pens/treatment).

The design of mixed-dimensional heterostructures has emerged to be a new frontier of research as it induces exciting physical/chemical properties that extend beyond the fundamental properties of single dimensional systems. Therefore, rational design of heterostructured materials with novel surface chemistry and tailored interfacial properties appears to be very promising for the devices such as the gas sensors. Here, a highly sensitive gas sensor device is constructed by employing heterostructures of boron doped molybdenum disulfide quantum dots (B-MoS Qdots) assembled into the matrix of TiCT MXene.

The feasibility of carbon mineralization relies on the carbonation efficiency of CO-reactive minerals, which is largely governed by the water content and state within material mesopores. Yet, the pivotal role of confined water in regulating carbonation efficiency at the nanoscale is not well understood. Here, we show that the maximum CO intake occurs at an optimal relative humidity (RH) when capillary condensation initiates within the hydrophilic mesopores.

Nosema ceranae and Lotmaria passim are two commonly encountered digestive tract parasites of the adult honey bee (Apis mellifera L.). Although these parasites are associated with colony losses, little is known about how they affect individual bee physiology and behaviour at the colony level.

Mupirocin is an effective antibiotic for infectious skin diseases. However, mupirocin is formulated as an ointment and is difficult to apply in canine systemic pyoderma. Therefore, many clinicians reformulate mupirocin off-label ointment into a spray.
