    Abstract: The article highlights the powerful influence of contractor selection in improving road project performance in Uganda. It provides empirical evidence of the performance of road projects as a less studied phenomenon because in Uganda, most public works are delivered with longer delays, contracts are more often awarded to larger suppliers and a higher share of the payment is postponed after delivery. Use of poor-quality materials, poor scheduling, delayed procurement, and poor contractor selection causes cost and time overruns on roads. The study adopts a cross sectional design in terms of quantitative and qualitative approaches to collect data. A multivariate analysis and surveys were taken from 190 respondents. It was found that contractor monitoring has a significant positive effect on the completion of roads while contractor selection has a direct and indirect positive effect on performance of roads through the partial mediation of contractor selection. This suggests that contractor selection has an effect on the improvement of the level of road projects performance in Uganda. There is a need to improve the scrutiny of the contractor selection process in road agencies in Uganda. This will require a good review of the government policy on contractor selection aimed at making it more robust and efficient

    Risk of End-Stage Renal Disease in HIV-Positive Potential Live Kidney Donors

    New federal regulations allow HIV-positive individuals to be live kidney donors; however, potential candidacy for donation is poorly understood given the increased risk of end-stage renal disease (ESRD) associated with HIV infection. To better understand this risk, we compared the incidence of ESRD among 41 968 HIV-positive participants of North America AIDS Cohort Collaboration on Research and Design followed for a median of 5 years with the incidence of ESRD among comparable HIV-negative participants of National Health and Nutrition Examination III followed for a median of 14 years. We used risk associations from multivariable Cox proportional hazards regression to derive cumulative incidence estimates for selected HIV-positive scenarios (no history of diabetes, hypertension, AIDS, or hepatitis C virus coinfection) and compared these estimates with those from similarly selected HIV-negative scenarios. For 40-year-old HIV-positive individuals with health characteristics that were similar to those of age-matched kidney donors, viral load <400 copies/mL, and CD4+ count ≥500 cells/μL, the 9-year cumulative incidence of ESRD was higher than that of their HIV-negative peers, yet still low: 2.5 versus 1.1 per 10 000 among white women, 3.0 versus 1.3 per 10 000 among white men, 13.2 versus 3.6 per 10 000 among black women, and 15.8 versus 4.4 per 10 000 among black men. HIV-positive individuals with no comorbidities and well-controlled disease may be considered low-risk kidney donor candidates

    Doctor can I buy a new kidney? I've heard it isn't forbidden: what is the role of the nephrologist when dealing with a patient who wants to buy a kidney?

    Organ trafficking is officially banned in several countries and by the main Nephrology Societies. However, this practice is widespread and is allowed or tolerated in many countries, hence, in the absence of a universal law, the caregiver may be asked for advice, placing him/her in a difficult balance between legal aspects, moral principles and ethical judgments. In spite of the Istanbul declaration, which is a widely shared position statement against organ trafficking, the controversy on mercenary organ donation is still open and some experts argue against taking a negative stance. In the absence of clear evidence showing the clinical disadvantages of mercenary transplantation compared to chronic dialysis, self-determination of the patient (and, with several caveats, of the donor) may conflict with other ethical principles, first of all non-maleficence. The present paper was drawn up with the participation of the students, as part of the ethics course at our medical school. It discusses the situation in which the physician acts as a counselor for the patient in the way of a sort of “reverse” informed consent, in which the patient asks advice regarding a complex personal decision, and includes a peculiar application of the four principles (beneficence, non-maleficence, justice and autonomy) to the donor and recipient parties
