s who fell (relative risk 0.117, 95% confidence interval 0.035-0.384). Conclusion The combination of alendronate sodium with alfacalcidol and calcium can significantly improve the bone mineral density of the lumbar spine and femoral neck. For older patients with OPA, subjectively paying attention to avoiding falls can significantly reduce the risk of fragility fractures.Background Lung cancer is the leading cause of cancer-related deaths. Although epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are effective for advanced non-small cell lung cancer (NSCLC) harboring EGFR mutations, some patients experience little or no response. The Glasgow prognostic score (GPS) is an inflammation-related score based on C-reactive protein (CRP) and albumin concentrations, and has prognostic value in various cancer settings. This study aimed to evaluate whether GPS could predict response of NSCLC to EGFR-TKIs. selleck Methods This retrospective multicenter study evaluated patients with NSCLC harboring EGFR mutations who received EGFR-TKI monotherapy from October 2006 to December 2016. GPS values were determined using CRP and albumin concentrations from before initiation of EGFR-TKIs. link2 The Kaplan-Meier method and Cox proportional hazard models were used to evaluate progression-free survival (PFS) and overall survival (OS). Results In 214 patients, 141, 43, and two patients had Gonse to EGFR-TKI treatment by using GPS.The expression of classical HLA class I antigens (HLA-I) on the surfaces of cancer cells allows cytotoxic T cells to recognize and eliminate these cells. Reduction or loss of HLA-I is a mechanism of escape from antitumor immunity. The present study aimed to investigate the clinicopathological impacts of HLA-I and non-classical HLA-I antigens expressed on pancreatic ductal adenocarcinoma (PDAC) cells. We performed immunohistochemistry to detect expression of HLA-I antigens in PDAC using 243 PDAC cases and examined their clinicopathological influences. We also investigated the expression of immune-related genes to characterize PDAC tumor microenvironments. Lower expression of HLA-I, found in 33% of PDAC cases, was significantly associated with longer overall survival. Higher expression of both HLA-E and HLA-G was significantly associated with shorter survival. Multivariate analyses revealed that higher expression of these three HLA-I antigens was significantly correlated with shorter survival. Higher HLA-I expression on PDAC cells was significantly correlated with higher expression of IFNG, which also correlated with PD1, PD-L1, and PD-L2 expression. In vitro assay revealed that IFNg stimulation increased surface expression of HLA-I in three PDAC cell lines. It also upregulated surface expression of HLA-E, HLA-G, and immune checkpoint molecules including PD-L1 and PD-L2. These results suggest that the higher expression of HLA-I, HLA-E, and HLA-G on PDAC cells is an unfavorable prognosticator. It is possible that IFNg promotes a tolerant microenvironment by inducing immune checkpoint molecules in PDAC tissues with higher HLA-I expression on PDAC cells.A 69-year-old woman was referred to our department with complaints of abdominal discomfort in the standing position. She had undergone robot-assisted radical cystectomy and ileal conduit urinary diversion for bladder cancer 10 months earlier. Abdominal CT revealed a parastomal hernia. Laparoscopic parastomal hernia repair using the Pauli technique was performed successfully with no recurrence after a 4-month follow-up. Although there are concerns about potential mesh-related complications and long-term results, this novel approach can be a successful option for parastomal hernia repair. As far as we know, this is the first English-language report on the application of Pauli parastomal hernia repair combined with a pure laparoscopic approach.Introduction High kVp techniques, 15% or 10-kVp rules, are well-known dose reduction methods. Traditionally, the use of high tube potential (i.e. increased kVp) is associated with decreased radiographic contrast and overall image quality. Recent studies suggest contrast and image quality are not heavily reliant on kVp with digital systems. This study aims to assess the effects of the high tube potential technique on clinical radiographic image quality when using digital systems, to validate high kVp as a dose saving technique. Methods A selection of comparable pelvis and lumbar spine radiographs were collected from the hospital's picture archiving and communication system (PACS), with technical factors recorded. All clinical radiographs were assessed by 5 senior radiographers using a 15-point visual grading analysis (VGA) rubric. Results For 40 AP pelvis radiographs and 40 lateral lumbar spine radiographs, reduction in the dose area product (DAP) with higher kVp is seen. Average pelvis DAP at 75 kVp = 14.06 mGy.cm2 ; 85 kVp = 7.47 mGy.cm2 . Average lumbar spine DAP at 80 kVp = 15.76 mGy.cm2 ; 90 kVp = 14.83 mGy.cm2 . Image quality and contrast scores showed no statistically significant difference between the high and low kVp groups (z = 0.06 and 0.12, respectively). Average pelvis VGA score at 75 kVp = 11.26; 85 kVp = 12.55. Average lumbar spine VGA score at 80 kVp = 9.23; 90 kVp = 10.64. Conclusions The high tube potential techniques allowed for reduced patient radiation doses whilst showing no degradation of diagnostic image quality in a clinical setting. This study successfully validates the high kVp technique as a useful tool for reducing patient radiation doses whilst maintaining high diagnostic image quality for digital pelvis and lumbar spine radiography.Introduction There is limited literature on the appropriateness of viral load (VL) monitoring and management of detectable VL in public health settings in rural South Africa. Methods We analysed data captured in the electronic patient register from HIV-positive patients ≥ 15 years old initiating antiretroviral therapy (ART) in 17 public sector clinics in rural KwaZulu-Natal, during 2010-2016. We estimated the completion rate for VL monitoring at 6, 12, and 24 months. We described the cascade of care for those with any VL measurement ≥ 1000 HIV-1 RNA copies/mL after ≥ 20 weeks on ART, including the following proportions (1) repeat VL within 6 months; (2) re-suppressed; (3) switched to second-line regimen. Results There were 29 384 individuals who initiated ART during the period [69% female, median age 31 years (interquartile range 25-39)]. Of those in care at 6, 12, and 24 months, 40.7% (9861/24 199), 34% (7765/22 807), and 25.5% (4334/16 965) had a VL test at each recommended time-point, respectively. The VL results were documented at all recommended time-points for 12% (2730/22 807) and 6.2% (1054/16 965) of ART-treated patients for 12 and 24 months, respectively. Only 391 (18.3%) of 2135 individuals with VL ≥ 1000 copies/mL on first-line ART had a repeat VL documenting re-suppression or were appropriately changed to second-line with persistent failure. Completion of the treatment failure cascade occurred a median of 338 days after failure was detected. Conclusion We found suboptimal VL monitoring and poor responses to virologic failure in public-sector ART clinics in rural South Arica. Implications include increased likelihood of morbidity and transmission of drug-resistant HIV.Introduction As most patients with epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) develop progressive disease after treatment with osimertinib, it is important to develop more effective treatment options. Afatinib has been shown to be more effective in in vitro studies than osimertinib when used in cancer cell lines containing some specific EGFR mutations. Therefore, afatinib may be an effective solution, especially when used in combination with an anti-VEGF agent such as bevacizumab. Methods A phase II multicenter, open-label, single-arm trial has been initiated to evaluate the efficacy and safety of afatinib and bevacizumab combination as salvage therapy for EGFR-mutated lung cancer in patients previously treated with osimertinib. The primary endpoint will be the objective response rate (ORR) and secondary endpoints are progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and adverse events (AEs). Discussion A previous study indicated that afatinib inhibits lung cancer cells with specific EGFR mutations more effectively than other EGFR-TKIs such as osimertinib. Therefore, we expect that combination therapy using afatinib and bevacizumab will be effective in patients previously treated with osimertinib (registration no. jRCTs031190077).Introduction There are increasing concerns about radiation exposure among women who undergo full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT). The main aim of this study was to compare the entrance surface dose (ESD) and average glandular dose (AGD) from FFDM and DBT for different breast thicknesses. Methods The ESD and AGD for FFDM in craniocaudal, mediolateral oblique and DBT in craniocaudal projection were recorded from a GE Senographe Essential FFDM unit. The accuracy of the ESD and AGD from the FFDM unit was verified during regular quality assurance programme. Patients were categorised according to their compressed breast thicknesses. X-ray tube potential and target filter combinations were varied with ESD and AGD recorded directly from the FFDM unit. The non-parametric Kruskal-Wallis, Mann-Whitney and Wilcoxon signed-rank tests were performed. Results The median and interquartile range (IQR) age of the patients were 48 and 11 years, respectively. The highest median for ESD and median total AGD for different breast thicknesses were ranged from 3.3 to 9.1 mGy and 3.3 to 6.0 mGy, respectively, for two-view FFDM. However, it ranged from 3.1 to 8.9 mGy and 1.8 to 4.0 mGy, respectively, for single-view DBT. Both ESD and AGD were significantly lower for DBT (P less then 0.001) compared with FFDM. link3 There was a significant difference (P = 0.001) in the ESD and AGD values for different breast thicknesses in FFDM and DBT techniques. Conclusions The AGD for a single-view DBT was lower than the two-view FFDM technique.Our systematic review compiled multiple studies and evaluated survivorship and clinical outcomes of cup-cage construct usage in the management of massive acetabular bone defects. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Various combinations of "acetabular", "pelvis", "cup cage" and their corresponding synonyms were used to search relevant articles in the Cochrane, EMBASE, and PubMed databases. Basic information of the functional scores, implant revision rate, and complication rate were selected as outcomes for analysis. Finally, a total of 11 articles published between 1999 and 2019 were selected, which include 232 patients with an average age of 68.5 years (range, 30-90). The mean follow-up period was 48.85 months (range, 1-140). Our study shows that the cup-cage construct has a good clinical outcome with a low revision rate and a low complication rate. Improved clinical outcomes of cup-cage constructs were seen with a revision rate of 8% and an all-cause complication rate of 20%.
