BACKGROUND The prognostic nutritional index (PNI), an immunity and nutrition based prognostic score, was correlated with clinical outcomes in different tumors. However, the prognostic significance of PNI has not been investigated in hormone sensitive prostate cancer (PCa). The objective of this study was to determine the prognostic significance of PNI in hormone sensitive PCa. METHODS Two hundred eighty PCa patients undergoing androgen deprivation therapy (ADT) as first line therapy at three centers were enrolled. The serum albumin levels and peripheral lymphocyte count were measured at the time of diagnosis. PNI was calculated as 10 * serum albumin (g/dL) + 0.005 * total lymphocyte count (per mm3). Patients were categorized in two groups using a cut-off point of 50.2 as calculated by the receiver-operating curve analysis. Univariate and multivariate cox regression analyses were performed to evaluate PNI as a favorable prognostic factor for progression-free survival (PFS), cancer-specific survival (CSS) and overall survival (OS). Prognostic accuracy was evaluated with the Harrell concordance index. RESULTS Multivariate analyses identified PNI as an independent prognostic indicator with respect to PFS (hazard ratio (HR) = 0.521, p&nbsp;= 0.001), CSS (HR = 0.421, p&nbsp;= 0.002) and OS (HR = 0.429, p&nbsp;= 0.001). Patients with elevated PNI had better clinical outcomes. The addition of PNI to the final models improved predictive accuracy (c-index 0.758, 0.830 and 0.782) for PFS, CSS and OS compared with the clinicopathological base models (c-index 0.736, 0.801 and 0.752), which included Gleason score and incidence of metastasis. CONCLUSIONS Elevated pretreatment PNI was a favorable prognostic indicator for PCa patients treated with ADT.BACKGROUND Diarrheal and acute respiratory infections remain a major cause of death in developing countries especially among children below 5 years of age. About 80% of all hospital attendances in Kenya can be attributed to preventable diseases and at least 50% of these preventable diseases are linked to poor sanitation. The purpose of this study was to assess the impact of a community-based health education program, called Familia Nawiri, in reducing the risk of diarrhea and respiratory infections among people living in three rural Kenyan communities. METHODS Cases were defined as patients attending the health facility due to diarrhea or a respiratory infection while controls were patients attending the same health facility for a non-communicable disease defined as an event other than diarrhea, respiratory infection. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a logistic regression model to assess the risk of diarrheal or respiratory infection in association with exposure to the health education program. RESULTS There were 324 cases and 308 controls recruited for the study with 57% of the cases and 59% of the controls being male. Overall, 13% of cases vs. 20% of control patients were exposed to the education program. Participants exposed to the program had 38% lower odds of diarrhea and respiratory infections compared to those not exposed to the program (adjusted OR 0.62, 95% CI 0.41-0.96). A similar risk reduction was observed for participants in the study who resided in areas with water improvement initiatives (adjusted OR 0.65, 95% CI 0.47-0.90). Variables in the adjusted model included water improvement projects in the area and toilet facilities. CONCLUSION Findings from this study suggest participants exposed to the education program and those residing in areas with water improvement initiatives have a reduced risk of having diarrhea or respiratory infection.BACKGROUND Whether ligation of the dorsal branch of the cephalic vein during the surgical establishment of the radiocephalic arteriovenous fistula (RCAVF) favorably or adversely affects the patency rate of the RCAVF remains controversial. We performed a randomized controlled trial to evaluate the effect of dorsal branch ligation on the patency rate of RCAVF. METHODS A total of 115 patients who underwent surgical establishment were randomized to two groups treated with or without ligation of the dorsal branch of the cephalic vein during the surgical process. The primary patency rates of the RCAVF at 90, 270, and 360 days after the surgery and the secondary patency rates during a follow-up up to 1 year were compared. RESULTS The patency rate did not differ significantly between the two groups at 3, 9, or 12 months after the procedure (P&nbsp;&gt; 0.05). The combined primary patency rates of the RCAVF in patients from both groups at 3, 9 and 12 months after the procedure were 87.6, 82, and 74.5% respectively, while the combined secondary patency rate was 92.2% at the 1-year follow-up. The Log-rank test indicated that the initial patency rate and secondary patency rate did not differ significantly between the two groups (P&nbsp;= 0.674 and 0.759, respectively).

Pars interarticularis (PI) fracture is a potential rare cause of suspected spinal CSF leak. METHODS This is a retrospective case series of 6 patients with suspected spinal CSF leak evaluated between January 2016 and September 2019. All patients received a magnetic resonance imaging (MRI) of the brain with and without gadolinium, MRI whole spine and full spine computed tomography (CT) myelogram. Targeted epidural patches with fibrin sealant were performed. Treatment response at return visit (3 months post-patch) was documented. RESULTS Six patients (4 females, 2 males) were diagnosed with a suspected spinal CSF leak and PI fracture. Mean age at the time of headache onset was 39 years old, and a range from 32 to 50 years old. Mean time to targeted epidural patches with fibrin sealant was 4.5 years. All 6 patients had PI fractures identified on CT myelogram and received targeted epidural patches with fibrin sealant at the site of the PI fracture.
