Decreasing cancer occurrence in the aging adults: lowering analytic depth as well as chemistry and biology?
This meta-analysis aimed to evaluate the variation in the diagnostic criteria for chronic endometritis (CE) and its effect on reproductive outcomes. A search of the academic literature was conducted in various databases including PubMed, Embase, Cochrane Library, and Chinese National Knowledge Internet. Studies published in English or Chinese prior to October 1, 2019, were included in the primary screen. Data on the CE incidence rate, cure rate after antibiotic therapy, clinical pregnancy rate, miscarriage rate, and live birth rate were extracted and analyzed. Twelve eligible studies involving 1879 patients were included in this meta-analysis. Compared with strict diagnostic criteria, studies that used broad diagnostic criteria to identify CE reported a higher incidence rate (odds radio [OR] = 2.96, 95% confidence interval [CI] 1.13-6.44), clinical pregnancy rate (OR = 1.83, 95 % CI 1.18-2.8), and live birth rate (OR = 2.08, 95 % CI 1.43-3.02). Compared with a short treatment course, a longer course of antibiotic treatment significantly improved the cure rate of CE (OR = 0.29, 95% CI 0.18-0.47). Based on these findings, variation in the diagnostic criteria may alter the incidence rate, clinical pregnancy rate, and live birth rate of women with CE. A consensus on the diagnostic criteria must be established to obtain a better understanding of and additional information about CE.There is need to confirm the presence of Theileria orientalis among the cattle population in Peninsular Malaysia and to evaluate the risk factors associated with the infection. To this effect, blood samples were collected from 1045 cattle from 43 farms throughout the entire States of Peninsular Malaysia. The collected blood samples were subjected to DNA extraction and subsequent PCR amplification of the major piroplasm surface protein (MPSP) gene of the haemoprotozoan. Representative positive amplicons were purified, sequenced and compared with other sequences of the MPSP gene of T. orientalis curated from the GenBank. A well-structured questionnaire was used to get information about each cattle, it's demography, the bio-security, environmental and management factors. Univariate and multivariate analysis were used for the statistical evaluation, with significance set at p less then 0.05. A total prevalence of 49.76% (520/1045; 95% CI 46.73 - 52.79) was obtained. Types of breeds, age, production type, herd size, level of farm biosecurity, farm size, presence of other animal species in the farm, management systems and prophylaxis were significantly (p less then 0.05) associated with the prevalence of T. orientalis. This study confirmed the presence of T. orientalis and establish that the haemoprotozoan is endemic among cattle in Peninsular Malaysia.This paper presents a new analytical method to determine interface normals from a series of bright/dark field images taken from arbitrary orientations. This approach, based on a general geometrical model of interface projection, provides a generalized formulation of existing methods. It can treat an excessive number of inputs, i.e. orientation conditions. Given 6 or more sets of inputs, even with considerable experimental errors, we prove that this method is still very likely to yield results with satisfactory accuracy. The robustness of the method can thus allow its implementation in problems dealing with a large amount of data. We show that this method can also be applied to determine 1D features or to check the planarity of microstructural features.Background and purpose To identify a PSA threshold value at an intermediate follow-up time after low dose rate (LDR) prostate brachytherapy associated with cure, defined as long-term (10-15 year) freedom from prostate cancer. GA017 Materials and methods Data from 7 institutions for 14,220 patients with localized prostate cancer treated with LDR brachytherapy, either alone (8552) or with external beam radiotherapy (n = 1175), androgen deprivation (n = 3165), or both (n = 1328), were analyzed. Risk distribution was 42.4% favorable, 49.2% intermediate, and 8.4% high-risk. Patients with clinical failure before 3.5 years were excluded. Kaplan-Meier analysis was used with clinical failure (local, distant, regional or biochemical triggering salvage) as an endpoint for each of four PSA categories PSA ≤ 0.2, >0.2 to ≤0.5, >0.5 to ≤1.0, and >1.0 ng/mL. PSA levels at 4 years (±6 months) in 8746 patients without clinical failure were correlated with disease status at 10-15 years. Results For the 77.1% of patients with 4-year PSA ≤ 0.2, the freedom-from-recurrence (FFR) rates were 98.7% (95% CI 98.3-99.0) at 10 years and 96.1% (95% CI 94.8-97.2) at 15 years. Three independent validation cohorts confirmed 97-99% 10-year FFR rates with 4-year PSA ≤ 0.2. Successive PSA categories were associated with diminished disease-free rates at 10 and 15 years. PSA category was strongly associated with treatment success (p less then 0.0005). Conclusions Since 98.7% of patients with PSA ≤ 0.2 ng/mL at 4 years after LDR prostate brachytherapy were disease-free beyond 10 years, we suggest adopting this biochemical definition of cure for patients with ≥4 years' follow-up after LDR brachytherapy.The most frequent complications of osseointegrated implantation include implant-site infections, soft tissue overgrowth and failure of osseointegration. Bone overgrowth is also a complication at the abutment site and infrequently reported. We describe a rare case of difficult control and exuberant bone overgrowth, with total implant involvement, in a short period of time never before described in the literature. Bone growth around the implant is frequently underestimated and can be the cause of difficult control of skin reactions, that in some cases is just the "tip of the iceberg". Timely surgical review with removing excess bone may lead to implant preservation and control of skin reaction and healing.Background and objective Maxillary sinus disease is frequently observed in patients with unilateral cleft lip and palate (UCLP). The anatomical variations of maxillary sinus and maxilla may play a role in the high incidence of sinusitis. The aims of this study were to evaluate and compare the three-dimensional (3D) structural features of maxillary sinus and maxilla in UCLP adolescent patients between the defect and non-defect sides, and investigate the morphological relationship between the maxillary sinus and maxilla on the defect side by using cone-beam computed tomography (CBCT). Methods CBCT images were acquired from 42 UCLP adolescent patients. Maxillary sinus and maxilla on the defect and non-defect sides were segmented respectively and assessed three dimensionally, and the comparison was performed by paired t-test. A multiple linear regression was conducted to investigate the morphological relationship between the maxillary sinus and maxilla on the defect side. Results No statistically significant difference was observed in any parameter of the maxillary sinus between the defect and non-defect sides (P > 0.
