TL;DR: The first comprehensive analysis of the surgical workforce in Uganda is reported, identifying challenges to workforce development, and evaluating current programs addressing these challenges.
Abstract: Africa’s health workforce crisis has recently been emphasized by major international organizations. As a part of this discussion, it has become apparent that the workforce required to deliver surgical services has been significantly neglected. This paper reviews some of the reasons for this relative neglect and emphasizes its importance to health systems and public health. We report the first comprehensive analysis of the surgical workforce in Uganda, identify challenges to workforce development, and evaluate current programs addressing these challenges. This was performed through a literature review, analysis of existing policies to improve surgical access, and pilot retrospective studies of surgical output and workforce in nine rural hospitals. Uganda has a shortage of surgical personnel in comparison to higher income countries, but the precise gap is unknown. The most significant challenges to workforce development include recruitment, training, retention, and infrastructure for service delivery. Curricular innovations, international collaborations, and development of research capacity are some of the initiatives underway to overcome these challenges. Several programs and policies are addressing the maldistribution of the surgical workforce in urban areas. These programs include surgical camps, specialist outreach, and decentralization of surgical services. Each has the advantage of improving access to care, but sustainability has been an issue for all of these programs. Initial results from nine hospitals show that surgical output is similar to previous studies and lags far behind estimates in higher-income countries. Task-shifting to non-physician surgical personnel is one possible future alternative. The experience of Uganda is representative of other low-income countries and may provide valuable lessons. Greater attention must be paid to this critical aspect of the global crisis in human resources for health.

TL;DR: In this paper, the authors examined the effects of film thickness and substrate deformation restraint on the mechanical properties of electron beam (e-beam) deposited Au and Ag films using nanoindentation techniques.
Abstract: This paper presents the results of nanoindentation experimental studies of the contact-induced deformation in Au and Ag thin films. The paper examines the effects of film thickness and substrate deformation restraint on the mechanical properties of electron beam (e-beam) deposited Au and Ag films. Following a brief description of film microstructure, surface topography, and contact-induced pile-up deformation, film mechanical properties (hardness and Young's modulus) were determined using nanoindentation techniques. The indentation size effects (ISE) observed in films with different thicknesses were explained using a mechanism-based strain gradient (MSG) theory. The intrinsic film yield strengths and hardnesses extracted from the MSG theory are shown to exhibit classical Hall–Petch dependence on the inverse square root of the average film grain size. Displacement bursts were also found to occur in Ag films at indentation load levels of 100 μN. These were attributed to the initial onset of dislocation slip activity, when the shear stress exceeds the estimated theoretical shear strengths of the materials.

TL;DR: Significant similarities in antigen recognition profiles between the three African population groups were found, but there were also disparities, which may stem from genetic differences between both pathogen and host populations.
Abstract: Increasing knowledge about DosR regulon-encoded proteins has led us to produce novel Mycobacterium tuberculosis antigens for immunogenicity testing in human populations in three countries in Africa to which tuberculosis (TB) is endemic. A total of 131 tuberculin skin test-positive and/or ESAT-6/CFP10-positive, human immunodeficiency virus-negative adult household contacts of active pulmonary TB cases from South Africa (n = 56), The Gambia (n = 26), and Uganda (n = 49) were tested for gamma interferon responses to 7 classical and 51 DosR regulon-encoded M. tuberculosis recombinant protein antigens. ESAT-6/CFP10 fusion protein evoked responses in >75% of study participants in all three countries. Of the DosR regulon-encoded antigens tested, Rv1733c was the most commonly recognized by participants from both South Africa and Uganda and the third most commonly recognized antigen in The Gambia. The four most frequently recognized DosR regulon-encoded antigens in Uganda (Rv1733c, Rv0081, Rv1735c, and Rv1737c) included the three most immunogenic antigens in South Africa. In contrast, Rv3131 induced the highest percentage of responders in Gambian contacts (38%), compared to only 3.4% of Ugandan contacts and no South African contacts. Appreciable percentages of TB contacts with a high likelihood of latent M. tuberculosis infection responded to several novel DosR regulon-encoded M. tuberculosis proteins. In addition to significant similarities in antigen recognition profiles between the three African population groups, there were also disparities, which may stem from genetic differences between both pathogen and host populations. Our findings have implications for the selection of potential TB vaccine candidates and for determining biosignatures of latent M. tuberculosis infection, active TB disease, and protective immunity.

TL;DR: Collection of cough aerosol cultures is feasible and reproducible in a resource-limited setting and a minority of patients with TB produced culturable cough aerosols.
Abstract: 1.17;95%CI,1.07–1.33).Thewithin-test(kappa,0.81;95%CI,0.68– 0.94) and interday test (kappa, 0.62; 95% CI, 0.43–0.82) reproducibility were high. Conclusions: A minority of patients with TB (28%) produced culturable cough aerosols. Collection of cough aerosol cultures is feasible and reproducible in a resource-limited setting.

TL;DR: In the last 20 years, there has been an overall increase in the risk of cancer during the period in both sexes, with incidence rates of major cancers such as breast and prostate showing particularly marked increases (3.7% and 5.2% annually, respectively) as discussed by the authors.
Abstract: The Kampala cancer registry is the longest established in Africa. Trends in incidence rates for a 20-year period (1991-2010) for Kyadondo County (Kampala city and a rural hinterland) illustrate the effects of changing lifestyles in urban Africa, and the effects of the epidemic of HIV-AIDS. There has been an overall increase in the risk of cancer during the period in both sexes, with incidence rates of major cancers such as breast and prostate showing particularly marked increases (3.7% and 5.2% annually, respectively). In the 1960s cancer of the oesophagus was the most common cancer of men (and second in women), and incidence in the last 20 years has not declined. Cancer of the cervix, always the most frequent cancer of women, has shown an increase over the period (1.8% per year), although the rates appear to have declined in the last 4 years. HIV prevalence in adults in Uganda fell from a maximum in 1992 to a minimum (about 6%) in 2004, and has risen a little subsequently, while availability of antiretroviral drugs has risen sharply in recent years. Incidence of Kaposi sarcoma in men fell until about 2002, and has been relatively constant since then, while in women there has been a continuing decline since 2000. Other HIV related cancers-non-Hodgkin lymphoma of younger adults, and squamous cell carcinoma of conjunctiva-have shown major increases in incidence, although the former (NHL) has shown a small decline in incidence in the most recent 2 years.
