Kidney failure during HIV disease treated with tenofovir, multiple concurrent diseases and drug therapies

A significant case report of a HIV infected patient in his fifties who experienced an excellent virological and immunological response to antiretroviral therapy (which has been modified just to prevent or avoid some adverse events), but developed a severe, sudden acute kidney failure while under a polypharmacy due to some underlying and overwhelming disorders (i.e. arterial hypertension, non-insulin-dependent diabetes mellitus, a recent acute heart infarction with remarkable remnants, and finally an anecdotal muscle-joint pain with self-prescription of non-steroideal anti-inflammatory drugs), represents the key point for a debate around the increasing frequency of "polypharmacy" in the field of HIV infection, even when HIV resistance to antiretroviral is not a concern. The continuing increase of mean age of HIV-infected population, plus the existing, sometimes unmodifiable risk factors for cardiovascular, dysmetabolic, and renal disorders, plus the adjunct of anecdotal illnesses prompting the resort to different drugs and medications, either prescribed for HIV infection itself, or taken for concurrent or subsequent diseases, or self-prescribed occasionally due to an intercurrent, trivial disorders per se, may prompt a complicated scenario culminating with a life-threatening acute renal failure of tubular origin. Our report gives us the opportunity to revise and discuss the expected interactions between antiretroviral therapy and the even growing exposure to multiple different drug and drug classes, which may be responsible for relevant drug interactions and direct or adjunctive end-organ impairment, up to life-threatening conditions, which may be avoided or prevented by considering carefully all comorbidites and co-treatments potentially administered to HIV infected patients, thirty years after the discovery of AIDS

A singular case of cavernous internal carotid artery aneurysm in patient with cavernous sinus syndrome and bacterial meningitis

AbstractWe report the uncommon case of an acute cavernous sinus syndrome in a patient who was consequently discovered to have both a cavernous internal carotid artery aneurysm and bacterial meningitis. Which came first, the chicken or the egg? Which of the two, the aneurysm or the meningitis, gave rise to the patient’s symptoms? We briefly reviewed the literature of similar cases and tried to analyze the possible pathophysiological relationship between these findings. Moreover, this case highlights the importance of a multidisciplinary management of these patients to better decide between a medical and a surgical and/or endovascular treatment

The Interplay Between Digital Manufacturing and Dynamic Capabilities: An Empirical Examination of Direct and Indirect Effects on Firm Performance

Purpose The purpose of this paper is to identify and empirically examine the dynamic capabilities that drive the development of digital manufacturing capabilities (DMC) and the role of DMC in mediating their influence on firm performance. Design/methodology/approach Based on the dynamic capabilities view (DCV) of the firm, we develop a set of hypotheses that are tested through a survey of 110 managers in the manufacturing sector. The hypothesized model is tested through structural equation modeling (PLS-SEM). Findings The results indicate that although higher-order dynamic capabilities have a strong influence on firm performance, their effects are partially mediated by the digital manufacturing capabilities that they generate, by positively affecting the extended production process. Practical Implications Our analysis contributes to a better understanding of the interplay between levels of the dynamic capabilities hierarchy by finding that digital manufacturing capabilities play an important role in translating higher-order dynamic capabilities into enhanced firm performance. Originality By complementing the dynamic capability view with the disruptive innovation theory in a specific fast changing context, this study introduces a new construct (DMC) providing an original and considerable contribution to the literature. To the best of our knowledge, it is the first empirical study that includes and assesses all these elements together in the context of the manufacturing industry

Acute renal injury during HIV infection treated with combination antiretroviral therapy, and multiple underlying comorbidities and drug treatments. Implications of an underlying tenofovir therapy. An intriguing case report, and literature review

A significant case report of a HIV infected patient in his fifties who experienced an excellent virological and immunological response to antiretroviral therapy (which has been modified just to prevent or avoid some adverse events), but developed a severe, sudden acute kidney failure while under a polypharmacy due to some underlying and overwhelming disorders (i.e. arterial hypertension, non-insulin-dependent diabetes mellitus, a recent acute heart infarction with remarkable remnants, and finally an anecdotal muscle-joint pain with self-prescroption of non-steroideal anti-inflammatory drugs), represents the key point for a debate around the increasing frequency of “polypharmacy” in the field of HIV infection, even when HIV resistrance to antiretroviral is not a concern.The continuing increase of mean age of HIV-infected population, plus the existing, sometimes unmodifiable risk factors for cardiovascular, dysmetabolic, and renal disorders, plus the adjunct of anecdotal illnesses prompting the resort to different drugs and medications, either prescribed for HIV infection itself, or taken for concurrent or subsequent diseases, or self-prescibed occasionally due to an intercurrent, trivial disorders per se, may prompt a complicated scenario culminating with a lifethreatening acute renal failure of tubular origin.
