Acute kidney injury and vancomycin/piperacillin/tazobactam in adult patients: a systematic review.
The aim of this systematic review was to assess AKI (acute kidney injury) in adult patients, treated with vancomycin (V) + piperacillin/tazobactam (PT) compared to V monotherapy. Studies were found in Pubmed, Web of Science and Scopus databases. Articles not in English, pediatric studies and case reports were excluded. ⋯ The model showed a pooled significant higher risk of developing AKI [OR 2.77 (95% CI 1.94, 3.96), p < 0.0001] in V + PT group compared to V group. Association of V and PT appears to be associated with a greater risk of AKI compared to V in monotherapy. These results may serve as the impetus for further evaluation into true mechanisms behind this additive nephrotoxic effect and its potential implications on mortality.

Atrial fibrillation (AF) is a frequent pathology in Internal Medicine departments. The aim of our study was to identify the risk factors associated with the development of new-onset AF during hospitalization and to evaluate its outcome as in-hospital mortality. We conducted a retrospective case-control study on a cohort of 14,179 patients admitted to an internal medicine department. ⋯ The most frequent causes for hospitalization were sepsis, significantly higher in the case group. From the results of the multivariate analysis, the factors related independently to the development of AF were the presence of a number of comorbidities ≥ 3 (OR = 1.52; p = 0.017), sepsis as a reason of hospitalization (OR = 2, 16; p = 0.001) and glycemic value at the admission ≥ 130 mg/dL (OR = 1.44; p = 0.047). Both the length of hospital stay and in-hospital mortality were higher in the group of patients who developed AF, with a statistically significant difference compared to controls (p < 0.001).

Inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis, is an immune-mediated, chronic relapsing disorder characterised by severe gastrointestinal symptoms that dramatically impair patients' quality of life, affecting psychological, physical, sexual, and social functions. As a consequence, patients suffering from this condition may perceive social stigmatisation, which is the identification of negative attributes that distinguish a person as different and worthy of separation from the group. Stigmatisation has been widely studied in different chronic conditions, especially in mental illnesses and HIV-infected patients. ⋯ Likewise, resilience has been studied in different populations, age groups, and chronic conditions, especially mental illnesses and cancer, but little is known about this issue in patients with inflammatory bowel disease, even if this could be an interesting area of research. Resilience can be strengthened through dedicated interventions that could potentially improve the ability to cope with the disease. In this paper, we focus on the current knowledge of stigmatisation and resilience in patients with inflammatory bowel disease.

Randomized Controlled Trial
Two different techniques of ultrasound-guided peripheral venous catheter placement versus the traditional approach in the pre-hospital emergency setting: a randomized study.
We performed a randomized pre-hospital clinical study to compare two different techniques of ultrasound-guided peripheral venous catheter (PVC) insertion and the conventional cannulation technique in the pre-hospital emergency setting, with a specific focus on the procedural success rate and the time required to introduce PVC. This pre-hospital prospective controlled randomized clinical trial allocated patients treated by emergency medical service to undergo PVC insertion fully controlled by ultrasound (ultrasound guidance of the PVC tip until it penetrates the lumen, group A), PVC insertion partially controlled by ultrasound (target vein identification only, group B) or to receive PVC without any ultrasound guidance (group C). The study outcomes were monitored until the patient was admitted to the hospital. ⋯ The number of attempts was significantly lower (A: 1.18 ± 0.54, B: 1.05 ± 0.22, C: 1.22 ± 0.57, p < 0.001) and the time required for the procedure shorter (A: 75.3 ± 60.6, B: 43.5 ± 26.0, C: 82.3 ± 100.9 s, p < 0.001) in group B compared to groups A and C. Both techniques of ultrasound-guided PVC placement were associated with higher success rates than the conventional method. However, PVC insertion partially controlled by ultrasound was superior to full ultrasound guidance in terms of time and number of cannulation attempts required.

Antagonists of Vascular Endothelial Growth Factor (Anti-VEGF) are widely administered by intravitreal injection for the treatment of ocular pathologies such as Age-related Macular Degeneration, Diabetic Macular Edema, Proliferative Diabetic Retinopathy and occlusion of retinal vessels. Anti-VEGF agents, in particular bevacizumab, were introduced in oncology to inhibit tumor-induced angiogenesis feeding neoplastic tissues. Subsequently, other specific agents were developed for intraocular administration. ⋯ Nevertheless, clinical observations have raised the possibility that, even in these conditions, anti-VEGF agents may increase cardiovascular risk in patients who, being elderly and/or diabetic, are intrinsically prone to such events. This paper aims at reviewing the current knowledge on VEGF and its pharmacologic antagonists from mechanistic and side effect points of view, with specific reference to patients with sight-threatening conditions. Internists should be aware of the need to collaborate with ophthalmologists and pharmacovigilance operators to define as best as possible the risk/benefit balance of intravitreal agents in patients who might lose their sight if left untreated, or increase their risk of suffering a cardiovascular event if treated.
