RESUMO
OBJECTIVES: Miniaturization of percutaneous nephrolithotomy techniques have led to their increased consideration for lower pole renal stones that can prove more challenging to reach using retrograde intrarenal surgery. The objectives of the present study were to evaluate and compare the outcomes of miniaturized percutaneous nephrolithotomy (miniPCNL) and retrograde intrarenal surgery (RIRS) for the treatment of lower pole renal stones. MATERIALS AND METHODS: A retrospective study was performed in two academic urology departments between January 2016 and June 2019. Patients presenting with one or multiple stones of the lower calyx and/or renal pelvis, between 10 and 40mm based on CT-scan treated by miniPCNL or RIRS were included. RESULTS: In all, 115 miniPCNL and 118 RIRS procedures were included. The rate of patients with no significant residual fragment (stone free rate) after the first procedure was higher in the miniPCNL group (69% vs. 52% P=0.01), especially for stones>20mm (63% vs. 24% respectively, P<0.001) and stones with a density≥1000HU (69% vs. 42% respectively, P=0.009). The higher stone free rate of miniPCNL was confirmed in multivariate analysis, adjusting for stone size and number of stones, OR 4.02 (95% CI 2.08-8.11, P<0.0001). The overall postoperative complication rate was higher in the miniPCNL group than in the RIRS group (23% vs. 11%, P=0.01). A second intervention for the treatment of residual fragments was necessary for 9.6% of patients in the miniPCNL group versus 30.5% of patients in the RIRS group (P<0.001). Pre-stenting rate and duration of ureteral drainage (2 [1-8] vs. 25 days [7-37], P<0.001) were lower in the miniPCNL group. CONCLUSIONS: The stone free rate was higher after miniPCNL, especially for stones>20mm and with a density>1000 HU, but was associated with a higher risk of postoperative complications and a longer hospital stay. RIRS resulted in fewer complications at the cost of a higher retreatment rate and longer ureteral stenting. LEVEL OF EVIDENCE: 3.

This systematic review aimed to examine whether higher comorbidity burden, as assessed by comorbidity indices, was associated with a functional autonomy decline in individuals with cognitive impairment. The search was conducted in the following databases: PubMed/MEDLINE, ScienceDirect, Cochrane, and Embase. Both cross-sectional and longitudinal studies that examined the relationship between comorbidity indices and scales measuring activities of daily living (ADL) in individuals with cognitive impairment were included. The quality assessment tool for observational cohort and cross-sectional studies of the National Institutes of Health (NIH) was used. Overall, 12 studies were included, among which three were longitudinal. Significant association was frequently reported by cross-sectional designs (n=7 studies) and only one study reported a significant longitudinal association. This longitudinal study repeatedly assessed both comorbidity burden and functional autonomy, and considered comorbidity burden as a time-varying covariate. Considering comorbidity burden as a time varying covariate may deal with the dynamic nature of comorbidity burden over time, and conducting repeated assessments during the follow-up using both comorbidity index and ADL scales may increase their sensitivity to reliably measure comorbidity burden and functional autonomy decline over time. In conclusion, a higher comorbidity index was associated with a lower level of functional autonomy in people with cognitive impairment. This relationship seems to be dynamic over time and using comorbidity indices and ADL scales only once may not deal with the fluctuation of both comorbidity burden and functional autonomy decline. To cope with complexity of this relationship this review highlights some methodological approaches to be considered.

Systemic diseases, which are in France mainly monitored in internal medicine, affect multiple organs or tissues. While cutaneous or articular manifestations are the most common, neurological involvement is often associated with severity. Diagnosis of peripheral (e.g, neuropathies) or central (e.g, myelitis) nervous disorders is quite easy through clinical examination and dedicated complementary tests. However, neuropsychological manifestations that affect cognition, including memory, attention, executive functions or reasoning, are difficult to diagnose, sometimes trivialized by practitioners. Their causes are often numerous and interrelated. Nevertheless, these cognitive manifestations are closely related to patients' quality of life, affecting their social life, family dynamics and professional integration but also the treatment adherence. The purpose of this review, focused on the example of systemic lupus erythematosus, is to raise awareness of cognitive dysfunction in systemic diseases including their management from diagnosis to treatments. The final aim is to go further into setting up research groups and care programs for patients with cognitive impairment followed in internal medicine.

BACKGROUND: Alzheimer's disease and related diseases (ADRD) are a major cause of health-related cost increase. OBJECTIVES: This study aimed to estimate the real medical direct costs of care of patients followed at a memory center, and to investigate potential associations between patients' characteristics and costs. DESIGN: Cross-sectional analyses conducted on matched data between clinical data of a cohort of patients and the claims database of the French Primary Health Insurance Fund. SETTING: Memory center in France. PARTICIPANTS: Patients attending a memory center with subjective cognitive complaint. MEASUREMENTS: Medical or nonmedical direct costs (transportation) reimbursed by the French health insurance during the one year after the first memory visit, and socio-demographic, clinical, cognitive, functional, and behavioral characteristics were analyzed. RESULTS: Among 2,746 patients (mean ± SD age 79.9 ± 8 years, 42.4% of patients with dementia), the total direct cost was on average 9,885 per patient during the year after the first memory visit: 7,897 for patients with subjective cognitive complaint, 9,600 for patients with MCI, and 11,505 for patients with dementia. A higher functional and cognitive impairment, greater behavioral disorders, and a higher caregiver burden were independently associated with a higher total direct cost. A one-point decrease in the Instrumental Activities of Daily Living score was associated with a 1,211 cost increase. The cost was higher in patients with Parkinson's disease, and Lewy body disease compared to patients with AD. Diabetes mellitus, anxiety disorders and number of drugs were also significantly associated with greater costs. CONCLUSIONS: Higher real medical direct costs were independently associated with cognitive, functional, and behavioral impairment, diabetes mellitus, anxiety disorders, number of drugs, etiologies as well as caregiver burden in patients attending a memory center. The identification of factors associated to higher direct costs of care offers additional direct targets to evaluate how interventions conducted in patients with NCD impact direct costs of care.

White matter hyperintensities (WMH), also known as leukoaraïosis are very common neuroradiological manifestations in the elderly. The main risk factors for WMH are age and high blood pressure. The vascular origin of these lesions is classically accepted and WMH are considered as one feature of the small vessel disease. WMH may be associated with clinical symptoms, depending notably on their importance according to age. They are associated with increased mortality, strokes and changes in cognition with a higher risk of dementia (vascular dementia or Alzheimer's disease). Modification of vascular risk factors could have a beneficial effect, but few evidences from controlled trials are available.
