Mindfulness and compassion training for health professionals: A qualitative study.

Background: Compassion is a key component of quality care. Encouraging Health Care Professionals (HCPs) to develop a patient-centered care relationship through mindfulness and compassion training may be beneficial for both patients and HCPs. Method: We assessed the impact of a compassion-centered mindfulness program [i.e., the Mindfulness Based (MB) CARE program] on healthcare practice conducting 10 phone interviews with HCPs who experienced the program. Results: The training had an overall positive impact on the HCPs ability to feel compassion toward their patients and themselves, helped them develop kindness toward themselves and their patients, and enhanced their attention to their patient's needs and theirs. Participants were better able to accept the difficult work experiences or those their patients experienced, with more perceived equanimity and less reactivity. Conclusion: Professional mindfulness and compassion training programs could be operational levers for institutions aiming at fostering more compassionate HCPs-patients relationships.

[Hyperthyroidism-induced calciphylaxis: A case report]. / Calciphylaxie dans un contexte de maladie de Basedow : à propos d'un cas.

BACKGROUND: Calciphylaxis or calcific uremic arteriolopathy (CUA) is a cutaneous disease with ulcerations secondary to calcification of cutaneous and subcutaneous small arteries and arterioles. It is a rare but severe disease with significant morbidity and mortality affecting 1 to 4% of dialysis patients. The circumstances of occurrence are multiple. CASE: We report the case of a severe bilateral lower limb calciphylaxis in a 69-year-old, obese, hemodialysis patient with a recent diagnosis of Graves' disease complicated with hypercalcemia and cardiac arrhythmia requiring the use of vitamin K antagonist. Complex and multidisciplinary therapeutic management (daily hemodialysis, sodium thiosulfate therapy, treatment of hypercalcemia by denosumab, hyperbaric oxygen therapy, meshed skin autograft) allowed complete healing of the lesions. CONCLUSION: This is the first description of AUC secondary to hyperthyroidism in a dialysis patient. Multidisciplinary care is essential to achieve clinical improvement in those critical situations.

Antiretroviral therapy as a risk factor for chronic kidney disease: Results from traditional regression modeling and causal approach in a large observational study.

OBJECTIVE: We investigated whether patients receiving selected antiretroviral combinations had a higher risk of chronic kidney disease (CKD) using traditional regression modeling and a causal approach in a large prospective cohort. PATIENTS AND METHODS: For the purpose of this study, we selected 6301 patients who (i) started their first antiretroviral regimen after 1st January 2004, (ii) had at least one serum creatinine measurement within 6 months before ART initiation (study entry), and (iii) had at least two measurements after study entry. Baseline eGFR was defined from the last serum creatinine measurement before study entry. All eGFR values were calculated using the Modification of Diet and Renal Disease (MDRD) equation. Both traditional Cox proportional hazards model and Cox marginal structural models were applied. Distinct coding for antiretroviral therapy exposure were investigated as well as double robust estimators. RESULTS: Overall we showed that patients receiving tenofovir (TDF) with a ritonavir boosted protease inhibitor (rbPI) exhibited a higher risk of CKD compared with patients who received TDF with a non-nucleosidic reverse transcriptase inhibitor (NNRTI). Such an increased risk was observed considering both initial and current regimens. Our analysis revealed a clinician-driven switch away from TDF among persons experiencing a decline in renal function while receiving this drug. CONCLUSION: Our results show that combination of TDF and boosted protease inhibitor is associated with a higher CKD risk than TDF and a NNRTI.

[Renal physiology]. / Physiologie rénale.

The kidneys are responsible for the urinary excretion of uremic toxins and the regulation of several body systems such as intra and extracellular volume status, acid-base status, calcium and phosphate metabolism or erythropoiesis. They adapt quantitative and qualitative composition of the urine to keep these systems in balance. The flow of plasma is filtered in the range of 120 mL/min, and depends on the systemic and renal hemodynamics which is subject to self-regulation. The original urine will then be modified in successive segments of the nephron. The proximal nephron is to lead the massive reabsorption of water and essential elements such as sodium, bicarbonates, amino-acids and glucose. The distal nephron includes the distal convoluted tubule, the connector tube and the collecting duct. Its role is to adapt the quality composition of urine to the needs of the body.

Evolution of renal function in patients treated with antiangiogenics after nephrectomy for renal cell carcinoma.

PURPOSE: Side effects of antiangiogenic agents are moderate compared with other therapies. The most frequent adverse events are of a renovascular origin and manifest as hypertension (HTN) and thrombotic microangiopathy. To date, data are scanty on the renal tolerance of such drugs regarding renal function as itself, i.e., glomerular filtration rate (GFR). We report on the evolution of GFR in patients receiving antiangiogenic therapy after unilateral nephrectomy for kidney cancer. PATIENTS AND METHODS: Data from 73 patients followed in our oncology department for kidney cancer, who had undergone unilateral nephrectomy, and received any antiangiogenic therapy were reviewed. Their GFR was calculated using the aMDRD formula. RESULTS: All patients showed a declining renal function over time (-1.23 and -2.51 mL/min/1.73 m(2) using the slope of the curve or the difference between GFR at baseline and that at the end of treatment, respectively). Among them, patients who were recorded as having HTN before initiation of antiangiogenic therapy showed a higher decrease in their GFR of -13.28 and -12.06 mL/min/1.73 m(2). CONCLUSION: We recommend that blood pressure should be measured closely in those patients before initiation of antiangiogenic therapy. When HTN is diagnosed, it should be treated and renal function should be monitored since those patients may be at risk for rapidly decreasing renal function under therapy.

Herbs and the kidney.

The use of herbal therapy has increased dramatically in past years and may lead to renal injury or various toxic insults, especially in renal patients. In most countries, herbal products are not regulated as medicines. Herbal poisoning may be secondary to the presence of undisclosed drugs or heavy metals, interaction with the pharmacokinetic profile of concomitantly administered drugs, or association with a misidentified herbal species. Various renal syndromes were reported after the use of medicinal plants, including tubular necrosis, acute interstitial nephritis, Fanconi's syndrome, hypokalemia or hyperkalemia, hypertension, papillary necrosis, chronic interstitial nephritis, nephrolithiasis, urinary retention, and cancer of the urinary tract. It seems critical that caregivers be aware of the potential risk of such often underreported therapy and carefully question their patients about their use of this popular branch of alternative medicine.
