    BACKGROUND: Chronic kidney disease (CKD) is a major cause of morbidity and mortality in Sub-Saharan Africa (SSA). The majority of studies on CKD in SSA have been conducted among HIV-infected populations and mainly from large health facilities. We determined the prevalence of CKD and its predictors among populations in communities in central Uganda. METHODS: A cross-sectional study was conducted in Wakiso district using multi-stage sampling. Data was collected on age, sex, socio-economic status, history of alcohol intake, diabetes mellitus, hypertension and smoking. Measurement of blood pressure, weight and height to determine body mass index (BMI) and investigations including HIV testing, fasting blood sugar, creatinine and urinalysis were conducted. Logistic regression was used to estimate the strength of the association between variables and the presence of CKD estimated using the Cockcroft Gault formula. RESULTS: A total of 955 participants aged 18-87 years were enrolled into the study. The median age was 31 years (Interquartile range 24-42) and majority (67%) were female. Up to 21.4% (204/955) had abnormal renal function with CKD stage 1 in 6.2% (59/955), stage 2 in 12.7% (121/955), stage 3 in 2.4% (23/955), CKD stage 4 in 0% and CKD stage 5 in 0.1% (1/995). Female gender OR 1.8 (95% Confidence Interval [CI] 1.2-2.8), age >30 years OR 2.2(95% CI 1.2-3.8) and high social economic status OR 2.1 (95% CI 1.3-3.6) were associated with increased risk of CKD while BMI > 25Kg/m2 was protective against CKD OR 0.1 (95% CI 0.04-0.2). Traditional risk factors such as HIV-infection, diabetes mellitus, smoking and alcohol intake were not found to be significantly associated with CKD. CONCLUSION: We found a high prevalence of kidney disease in central Uganda. Interestingly the traditional risk factors associated with CKD previously documented, were not associated with CKD

    Brief of Intellectual Property Law Scholars As Amici Curiae in Support of Neither Party, WesternGeco LLC v. Ion Geophysical Corp., No. 16-1011, US Supreme Court

    This amici curiae brief was filed on behalf of Intellectual Property Law Scholars in WesternGeco LLC v. Ion Geophysical Corp. in the U.S. Supreme Court. The question presented is: Whether the U.S. Court of Appeals for the Federal Circuit erred in holding that lost profits arising from prohibited combinations occurring outside of the United States are categorically unavailable in cases in which patent infringement is proven under 35 U.S.C. § 271(f). In RJR Nabisco, Inc. v. European Community, 136 S. Ct. 2090 (2016), the Supreme Court articulated a two-step method for assessing the extraterritorial reach of a US statute: 1. A court should determine whether the presumption against extraterritoriality has been rebutted—that is, whether the statute gives a clear, affirmative indication that it applies extraterritorially. If the presumption is rebutted, the statute may have extraterritorial reach. 2. But even if the presumption has not been rebutted, a court should look at the focus of the statute. If the conduct relevant to the statute\u27s focus occurred in the United States, then the case involves a permissible domestic application even if other conduct occurred abroad; but if the conduct relevant to the focus occurred in a foreign country, then the case involves an impermissible extraterritorial application regardless of any other conduct that occurred in U.S. territory. The brief of amici curiae makes the follow points: 1. The Supreme Court has not squarely answered the question as to whether the presumption against extraterritoriality applies separately to remedial provisions of a statute generally (here whether it applies to § 284). We argue it does. 2. We argue that the territorial reach § 284 necessarily depends the relevant provision of § 271 used to find liability. Here, under § 271(f), the presumption is rebutted (though it would not be generally for a case under § 271(a), with NTP v. Research in Motion may be a counter-example when one looks at the focus at step 2)). 3. We also argue that the Court should offer more guidance as to what happens even if the RJR test is satisfied. RJR Nabisco seems to operate in binary fashion -- either the statute has extraterritorial reach or it doesn\u27t. But Microsoft Corp. v. AT&T Corp., and earlier Supreme Court decision also interpreting 35 U.S.C. § 271(f), suggests that the presumption may still have a role in interpreting a statute. We offer two suggestions on how the presumption should operate in this context. First, courts should seriously and formally consider issues of comity and potential conflicts with foreign law in assessing whether to apply U.S. law extraterritorially. Second, that territoriality should remain relevant in assessments of proximate cause

    Urinary-Cell mRNA Profile and Acute Cellular Rejection in Kidney Allografts

    Background—The standard test for the diagnosis of acute rejection in kidney transplants is the renal biopsy. Noninvasive tests would be preferable. Methods—We prospectively collected 4300 urine specimens from 485 kidney-graft recipients from day 3 through month 12 after transplantation. Messenger RNA (mRNA) levels were measured in urinary cells and correlated with allograft-rejection status with the use of logistic regression. Results—A three-gene signature of 18S ribosomal (rRNA)–normalized measures of CD3ε mRNA and interferon-inducible protein 10 (IP-10) mRNA, and 18S rRNA discriminated between biopsy specimens showing acute cellular rejection and those not showing rejection (area under the curve [AUC], 0.85; 95% confidence interval [CI], 0.78 to 0.91; P<0.001 by receiver-operatingcharacteristic curve analysis). The cross-validation estimate of the AUC was 0.83 by bootstrap resampling, and the Hosmer–Lemeshow test indicated good fit (P = 0.77). In an externalvalidation data set, the AUC was 0.74 (95% CI, 0.61 to 0.86; P<0.001) and did not differ significantly from the AUC in our primary data set (P = 0.13). The signature distinguished acute cellular rejection from acute antibody-mediated rejection and borderline rejection (AUC, 0.78; 95% CI, 0.68 to 0.89; P<0.001). It also distinguished patients who received anti–interleukin-2 receptor antibodies from those who received T-cell–depleting antibodies (P<0.001) and was diagnostic of acute cellular rejection in both groups. Urinary tract infection did not affect the signature (P = 0.69). The average trajectory of the signature in repeated urine samples remained below the diagnostic threshold for acute cellular rejection in the group of patients with no rejection, but in the group with rejection, there was a sharp rise during the weeks before the biopsy showing rejection (P<0.001). Conclusions—A molecular signature of CD3ε mRNA, IP-10 mRNA, and 18S rRNA levels in urinary cells appears to be diagnostic and prognostic of acute cellular rejection in kidney allografts
