Urea Level and Depression in Patients with Chronic Kidney Disease.

Depression is common in patients with chronic kidney disease (CKD). Experimental studies suggest the role of urea toxicity in depression. We assessed both the incidence of antidepressant prescriptions and depressive symptoms (measured by CESD (Center for Epidemiologic Depression) scale) in 2505 patients with CKD (Stage 3-4) followed up over 5 years in the Chronic Kidney Disease Renal Epidemiology and Information Network (CKD-REIN) cohort. We used a joint model to assess the association between the serum urea level and incident antidepressant prescriptions, and mixed models for the association between the baseline serum urea level and CESD score over the 5-year follow-up. Among the 2505 patients, 2331 were not taking antidepressants at baseline. Of the latter, 87 started taking one during a median follow-up of 4.6 years. After adjustment for confounding factors, the hazard ratio for incident antidepressant prescription associated with the serum urea level (1.28 [95%CI, 0.94,1.73] per 5 mmol/L increment) was not significant. After adjustment, the serum urea level was associated with the mean change in the CESD score (ß = 0.26, [95%CI, 0.11,0.41] per 5 mmol/L increment). Depressive symptoms burden was associated with serum urea level unlike depression events. Further studies are needed to draw firm conclusions and better understand the mechanisms of depression in CKD.

A New Approach for Cognitive Impairment Pattern in Chronic Kidney Disease.

BACKGROUND AND HYPOTHESIS: Chronic kidney disease (CKD) is associated with an elevated risk of neurocognitive disorders (NCDs). It remains unclear whether CKD-related NCDs have specific cognitive pattern or are earlier-onset phenotypes of the main NCDs (vascular NCDs and Alzheimer's disease). METHODS: We used the Mini Mental State Examination score (MMSE) to assess cognitive pattern in 3003 CKD patients (stage 3 to 4) followed up over 5 years in the Chronic Kidney Disease-Renal Epidemiology and Information Network (CKD-REIN) cohort. After normalizing MMSE scores to a 0-to-100 scale, the associations between the baseline estimated glomerular filtration rate (eGFR, using the CKD-EPI-creatinine formula) and changes in each MMSE domain score were assessed in linear mixed models. RESULTS: Patients (age: 67±13 years old; males: 65%, mean eGFR: 33±12 ml/min/1.73 m²) had a good baseline cognitive functions: the mean MMSE score was 26.9/30 ±2.9. After adjustment for age, sex, educational level, depression (past or present), cardiovascular risk factors, cerebrovascular disease, a lower baseline eGFR (per 10 ml/min/1.73 m²) was associated with a 0.53-point decrement (p<0.001; 95%CI [-0.98,-0.08]) for orientation, a 1.04-point decrement (p=0.03; 95%CI [-1.96,-0.13]) for attention and calculation, a 0.78-point decrement (p=0.003; 95%CI [-1.30,-0.27]) for language, and a 0.94-point decrement (p=0.02; 95%CI [-1.75,-0.13]) for praxis. Baseline eGFR was not, however, associated with significant changes over time in MMSE domain scores. CONCLUSION: A lower eGFR in CKD patients was associated with early impairments in certain cognitive domains: praxis, language and attention domains before an obvious cognitive decline. Early detection of NCD in CKD patients must be perform before clinically cognitive decline using preferably tests assessing executive, attentional functions and language than memory test. This could lead to a better management of cognitive impairment and their consequences on CKD management.

Importance of cytochrome 3A4 and 2D6-mediated drug-drug interactions in oxycodone consumption among older adults hospitalized for hip fracture: a cross-sectional study.

Hip fracture is a common injury and represents a major health problem with an increasing incidence. In older adults, opioids such as oxycodone are often preferred to other analgesics such as tramadol because of a lower risk of delirium. Different parameters, such as inhibition of cytochrome P450 (CYP450) 2D6 and/or 3A4, can potentially lead to pharmacokinetic variations of oxycodone representing a risk of adverse drugs effects or lack of drug response. There is a risk of drug-drug interactions involving CYP450 in older adults due to the high prevalence of polypharmacy. This study sought to identify patient characteristics that influence oxycodone administration. A single-center observational study included 355 patients with a hip fracture hospitalized in a geriatric postoperative unit. Composite endpoint based on form, duration, and timing to intake separated patients into three groups: "no oxycodone", "low oxycodone ", and "high oxycodone ". CYP450 interactions were studied based on a composite variable defining the most involved CYP450 pathways between CYP2D6 and CYP3A4. CYP450 interactions with CYP2D6 pathway involved were associated with the risk of "high oxycodone" [odds ratio adjusted on age and the type of hip fracture (OR*) 4.52, 95% confidence interval (CI) 1.39-16.83, p = 0.02)], as well as serum albumin levels (OR* 1.09, 95% CI 1.02-1.17, p = 0.01). Cognitive impairment was negatively associated with the risk of "high oxycodone" (OR* 0.38, 95% CI 0.18-0.77, p = 0.02). This study showed an association between CYP2D6 interactions and higher oxycodone consumption indirectly reflecting the existence of uncontrolled postoperative pain.

Real-life impact of respiratory panel PCR assay on antibiotic prescription in geriatric acute care in the pre-COVID-19 era.

OBJECTIVES: In this era of bacterial resistance, avoiding inappropriate use of antibiotic treatments is of major importance. Respiratory tract infections are frequent among older patients, and differentiating viral from bacterial infections is a challenge. The aim of our study was to evaluate the impact of recently available respiratory PCR testing on antimicrobial prescription in geriatric acute care. METHODS: We performed a retrospective study, including all hospitalized geriatric patients who had had multiplex respiratory PCR testing prescribed from 1st October 2018 to 30th September 2019. The PCR test comprised a respiratory viral panel (RVP) and a respiratory bacterial panel (RBP). PCR testing could be prescribed at any time during hospitalization by geriatricians. Our primary endpoint was antibiotic prescription after viral multiplex PCR testing results. RESULTS: All in all, 193 patients were included, 88 (45.6%) of whom had positive RVP, while none had positive RBP. Patients with positive RVP had significantly fewer antibiotic prescriptions following test results than patients with negative RVP (odds ratio (OR) 0.41, 95% confidence interval (CI) 0.22-0.77; p = 0.004). Among positive-RVP patients, factors associated with antibiotic continuation were presence of radiological infiltrate (OR 12.02, 95%CI 3.07-30.29), and detected Respiratory Syncytial Virus (OR 7.54, 95%CI 1.74-32.65). That said, discontinuation of antibiotic treatment seems safe. CONCLUSION: In this population, the impact of viral detection by respiratory multiplex PCR on antibiotic therapy was low. It could be optimized by means of clearly formulated local guidelines, qualified staff and specific training by infectious disease specialists. Cost-effectiveness studies are necessary.

Cognitive performance is associated with glomerular filtration rate in patients with chronic kidney disease: results from the CKD-REIN cohort.

BACKGROUND: Chronic kidney disease (CKD) is associated with cognitive impairment in general population. We assessed the association between kidney and cognitive functions in patients with CKD and the influence of cardiovascular (CV) risk factors, and depression on this association. METHODS: The CKD-Renal Epidemiology and Information Network cohort included 3033 patients with CKD stages 3-4, followed for 5 years. Cognitive function was assessed with the Mini-Mental State Examination (MMSE) and estimated glomerular filtration rate (eGFR) with the CKD-Epidemiology Collaboration equation-creatinin formula. Evolution of the MMSE score over time and its association with baseline eGFR were investigated with linear mixed models. We assessed the risk of incident cognitive outcome (hospitalisation or death with relevant International Classification of Disease-10 codes), with a Cox proportional hazard model. RESULTS: The mean age was 66.8, the mean eGFR was 33 mL/min/1.73 m2 and 387 patients (13.0%) had an MMSE score below 24 at baseline. A 10 mL/min/1.73 m2 decrement of baseline eGFR was associated with a mean MMSE decrease of 0.12 (95% CI 0.04 to 0.19) after adjustment for demographic characteristics, depression, CV risk factors and disease; but baseline eGFR was not associated with MMSE temporal evolution. HR for cognitive outcome during follow-up (median 2.01 years) associated with a 10 mL/min/1.73 m2 decrement of baseline eGFR was 1.35 (1.07, 1.70) (p=0.01) after adjustment. CONCLUSIONS: In patients with CKD, lower eGFR was associated with worse cognitive performance and incident cognitive events, independently of demographics, CV risk factors and depression. TRIAL REGISTRATION NUMBER: NCT03381950.

État des lieux des connaissances des internes sur le syndrome confusionnel et sa prise en charge chez le patient âgé agité.

Résumé La confusion est fréquente et grave chez le sujet âgé hospitalisé, alors qu'elle est souvent évitable. Plusieurs études sur les connaissances des infirmier(e)s et des médecins sur la confusion révèlent un manque de formation. En France, l'interne est souvent le prescripteur de première ligne en hospitalisation. Cette enquête nationale réalisée entre juin et décembre 2019 avait pour but d'évaluer les connaissances des internes sur la confusion et la prise en charge de sa forme hyperactive chez le sujet âgé.Pour cela, un auto-questionnaire a été élaboré à partir des recommandations de la Haute Autorité de santé (HAS) sur la confusion puis transmis via les réseaux sociaux aux internes. Ils sont 182 internes de 23 spécialités et de 18 villes différentes à y avoir répondu. Ils déclaraient être impliqués dans 97% des prises en charge alors que 45 % d'entre eux n'avaient pas connaissance des recommandations. La thérapeutique semblait être l'étape la plus difficile et les internes passés par une formation pratique en gériatrie obtenaient de meilleurs résultats.Les enjeux liés à la confusion et les recommandations de prise en charge thérapeutique sont mal connus des internes. La formation théorique mais surtout pratique en stage semble améliorer le niveau de connaissance. Abstract Delirium is frequent and serious, while it is often avoidable. Previous studies revealed a caregivers lack of knowledge about this syndrome concerning diagnosis and therapeutic management. In France, residents are often in first line to manage delirium patients. The purpose of this study is therefore to assess residents' level of knowledge about delirium and its therapeutic management in the elderly.Our study is a national survey carried out between June and December 2019 using a self-administrated survey derived from the 2009 Haute Autorité de santé (HAS) recommendations about delirium. The primary endpoint was the global score obtained by residents. The secondary endpoints were the score in different fields of competence (general knowledge, diagnostic, therapeutic) and the comparison of the resident's score according to their formation. One hundred eighty-two residents from 23 specialties and 18 different cities were represented. Residents were involved in more than 97% of the cases, while 45% of them were unaware of the HAS recommendations. Mean score to the survey was 68/100, and therapeutic management seemed the most difficult step, especially when the symptoms of delirium were severe. Our study highlights the benefit of practical training during internship to improve the level of knowledge on delirium.This study suggests the need for specific teaching on delirium. Training both theoretical and practical seems to be the most effective method. Development of a national educational program about delirium and its management could be proposed to improve residents awareness and develop their skill. Increasing the number of mobile geriatric teams and strengthen their action could also be a concrete option to improve delirium management. Finally, we could imagine the development of a pocket tool to offer a practical bedside help for clinicians. The development of such a tool would require further studies to evaluate its relevance and effectiveness.

Relevance of Cardiovascular Risk Factors Screening in People Aged over 65 Years: Results from a Large French Urban Population (The CARVAR92 Study).

BACKGROUND: Cardiovascular disease is the leading cause of death and disability in older people. Traditional cardiovascular risk factors (CVRFs) still have an impact on cardiovascular risk among older people. Nevertheless, screening campaigns rarely target subjects aged over 65 years. This study aimed to assess the distribution and relevance of conventional CVRF screening in people aged over 65 years. METHODS: Between 2007 and 2018, among a screening CVRF campaign in the western suburbs of Paris (32,692 subjects), we individualized 6,577 subjects aged 65 years and over. All conventional CVRFs have been systematically assessed. RESULTS: The screening allowed to suspect hypertension in a larger proportion of subjects over 65 years compared to subjects under 65 years (27% vs. 18%, p < 0.0001). Hypertension control was higher in women compared to men but not significantly different in the age-groups (p = 0.91). Screening for diabetes mellitus was positive in 3% of older subjects and 2.4% in younger (p = 0.005). Risk assessment with dedicated score (SCORE O.P.) allowed to move toward a low-risk estimation, resulting in the diminution of intermediate risk group in women over 65 years (from 68 to 61%, p < 0.001). CONCLUSIONS: Screening CVRFs especially hypertension remains relevant in people aged over 65 years as it enables to detect unknown CVRFs in numerous subjects. Increasing awareness of CVRFs may be the first step to CVRF control, which is known to be efficient on cardiovascular mortality and functional autonomy in later life.

Persistent eosinopenia is associated with in-hospital mortality among older patients: unexpected prognostic value of a revisited biomarker.

INTRODUCTION: Infection is one of the major causes of mortality and morbidity in older adults. Available biomarkers are not associated with prognosis in older patients. This study aimed to analyze the value of eosinopenia (eosinophil count< 100/mm3) as a prognosis marker among older patients with suspected or confirmed bacterial infection. METHODS: A retrospective study was performed from 1 January to 31 December 2018 among patients in a geriatrics ward suffering from a bacterial infection treated with antibiotics. Biomarker data including the eosinophil count, neutrophil count and C-reactive protein (CRP) were collected within 4 days after patient diagnosis. Persistent eosinopenia was defined as a consistent eosinophil count< 100/mm3 between Day 2 and Day 4. The association of biomarkers with 30-day hospital mortality in a multivariate analysis was assessed and their predictive ability using the area under the ROC curve (AUC) was compared. RESULTS: Our study included 197 patients with a mean age of 90 ± 6 years. A total of 36 patients (18%) died during their stay in hospital. The patients who died were more likely to have persistent eosinopenia in comparison to survivors (78% versus 34%, p < 0.001). In the multivariate analysis, persistent eosinopenia was associated with in-hospital mortality with an adjusted HR of 8.90 (95%CI 3.46-22.9). The AUC for eosinophil count, CRP and neutrophil count between Day 2 and Day 4 were 0.7650, 0.7130, and 0.698, respectively. CONCLUSION: Persistent eosinopenia within 4 days of diagnosis of bacterial infection appeared to be a predictor of in-hospital mortality in older patients.

Bloodstream infections in older population: epidemiology, outcome, and impact of multidrug resistance.

Bloodstream infections (BSIs) among older patients are frequent with high rate of mortality. Infections with multidrug-resistant organisms (MDRO) are associated with higher mortality than with susceptible microorganisms. We aimed to evaluate the prevalence of MDRO infection during BSI in older population and the factors associated with unfavorable outcome. This study is a retrospective cohort of all BSI episodes occurring among older patients (> 65yo), from April 1, 2010, to December 31, 2016, in a French university hospital for geriatric medicine. A total of 255 BSI episodes were analyzed. Mean age was 86.3±6.5 years, and sex ratio (M/F) was 0.96. Main comorbidities were orthopedic device (26.7%), active neoplasia (24.3%), and diabetes mellitus (18.4%). Main primary sites of infection were urinary tract infections (56.9%), respiratory tract infections (10.6%), intra-abdominal infections (7.1%), and skin and soft tissue infections (4.7%). Main bacteria identified were Escherichia coli (45.1%), Staphylococcus aureus (14.1%), enterococci (10.7%), coagulase-negative staphylococci (CoNS) (5.5%), and streptococci (5.1%). MDROs were involved in 17.2% of BSI (gram-negative bacilli: 9.0%; CoNS: 4.3%; and methicillin-resistant S. aureus (MRSA): 3.9%). The main factor associated with MDRO BSI was colonization with MDRO (OR=6.29; 95%CI=2.9-14.32). Total mortality was 18.4% and significantly higher in case of initial severity (OR=3.83; 95%CI=1.75-8.38), healthcare-associated infection (OR=5.29; 95%CI=1.11-25.30), and MRSA BSI (OR=9.16; 95%CI=1.67-50.16). BSI due to MDRO is frequent in older population and is strongly associated with carriage of MDRO. Healthcare-associated BSI, severe episodes, and BSI due to MRSA are associated with unfavorable outcome. In these cases, a broad-spectrum antibiotic should be promptly initiated.

Off-label use of midazolam in older inpatients: analysis of prescribing practices in a French hospital (MIDnight study).

Midazolam is a short-acting benzodiazepine approved for sedation and anesthesia induction. Recent data suggested that midazolam may also be used in off-label indications such as treatment of behavioral and psychological disturbances in older people. Given the scarcity of published data and a lack of evidence in older people in such indications, midazolam raises concern because it may also cause serious-related adverse events. To provide a better understanding of its real-life use in geriatrics, we examined the prescribing practices of midazolam in French older inpatients. Of the 460 patients aged 65 years and over hospitalized at the time of the study, 21 had a prescription of midazolam (5%) which was mainly prescribed for anxiolysis (n = 12), premedication before painful procedures (n = 5), and agitation (n = 4). Midazolam was often prescribed "as required," and the median duration of prescription was 6 months. This work results in a better knowledge and information about the use of midazolam in older people. These prescribing practices, which are not anecdotal, also plead for age-specific guidelines for the treatment of behavioral and psychological disturbances.

Rehospitalization following a stay in geriatric rehabilitation wards: rates and predictive factors.

Hospitalization in the elderly patients is highly associated with morbi-mortality. Geriatric post-acute and rehabilitation care wards are designed to provide care and to implement life project of elderly patients. Objective of this study was to characterize rehospitalizations after a stay in geriatric post-acute and rehabilitation care wards. METHODS: The study was retrospective, case-control, including all the patients hospitalized in the 4 geriatric post-acute and rehabilitation care wards of a hospital in Paris (France) and returned at home. Data collection was carried out on the basis of the hospitalization report and the information system of the hospital. Rehospitalizations were documented by the information system as well as by telephone interview. We compared patients according to whether they had been rehospitalized or not within 60 days after discharge. RESULTS: Out of a total of 1,063 stays during a 12 months period, 435 (41%) were discharged at home. Re-admission rate was 10.1% at 30 days and 18.4% at 90 days. Mean age of rehospitaliszed patients was 87.2 years ± 5.3 vs 87.9 years ± 5.8 for non-rehospitalized patients. Patients rehospitalized had more often a delirium during the prior hospitalization. CONCLUSION: Unplanned rehospitalisation is a major public health issue and should be prevented particularly after a stay in a geriatric post-acute and rehabilitation care wards.

Potentially inappropriate prescription of antidepressants in old people: characteristics, associated factors, and impact on mortality.

ABSTRACTBackground:The increasing use of antidepressants (ADs) has raised concerns about their inappropriate use in old people. OBJECTIVE: To examine the prevalence of potentially inappropriate prescribing (PIP) of ADs, their associated factors, and their impact on mortality in a sample of old people in France. METHODS: The analysis used data from the SIPAF study, a cross-sectional study consisting of 2,350 people aged ≥ 70 years. Trained nurses interviewed participants at home between 2008 and 2010. Information was collected concerning socio-demographic and health characteristics, including medication use. The study population consisted of the 318 AD users from the SIPAF study (13.5%). PIP of ADs was defined according to national and international criteria. Factors associated with PIP of ADs were assessed using a multivariate logistic regression model. The influence of PIP of ADs on mortality was assessed using a Cox model (median follow-up 2.8 years). RESULTS: Among the SIPAF study, 71% of AD users were female and the mean age was 84 ± 7 years. Selective serotonin reuptake inhibitors (SSRIs) were the most prescribed ADs (19.8%). We found PIP of ADs in 36.8% of the study population, mainly the co-prescription of diuretics with SSRIs (17.6%) and the prescription of tricyclics (12.9%). PIP of ADs was associated with polypharmacy (aOR5-9 drugs 2. 61, 95% CI 1.11-6.16 and aOR≥10 drugs 2.69, 95% CI 1.06-6.87) and comorbidity (aOR3-4 chronic diseases 2.59, 95%CI 1.04-6.44 and aOR≥5 chronic diseases 2.33, 95%CI 0.94-5.79), and increased the risk of mortality during follow-up (aHR 2.30, 95%CI 1.28-4.12). CONCLUSIONS: This study shows that more than one third of AD prescriptions may be inappropriate in old people. PIP of ADs was related to polypharmacy and comorbidity and increased mortality among AD users.

Oral Teicoplanin as an Alternative First-Line Regimen in Clostridium difficile Infection in Elderly Patients: A Case Series.

BACKGROUND: Elderly patients are more susceptible to Clostridium difficile infections (CDIs). Despite existing guidelines, there is no specific treatment for CDI in geriatrics. Vancomycin is commonly used in the treatment of CDI. Teicoplanin is an alternative glycopeptide which recently received marketing authorization approval for CDI in Europe. OBJECTIVES: Evaluate the potential interest of oral teicoplanin and assess whether such treatment could potentially become an alternative treatment in mild to severe CDIs in elderly patients. METHODS: A prospective monocentric study was conducted over 10 months (from December 2015 to October 2016) in a geriatric unit (Sainte Périne, AP-HP, Paris, France). According to the remote infectious disease specialist, some hospitalized patients suffering from CDI and aged over 65 years received oral teicoplanin 200 mg twice a day (highest dose recommended). The clinical response to teicoplanin and relapses after treatment were evaluated. Patients were monitored up to 90 days after teicoplanin administration, and analyzed in non-responder imputation analysis. RESULTS: Eleven patients received teicoplanin among 19 CDIs during the study time period. In non-responder imputation analysis, 90.9% (n = 10) successfully responded to oral teicoplanin. The rate of relapse observed after a 90-day follow-up was 36.4%. Patients reported no drug-related adverse effects. CONCLUSION: Oral teicoplanin is a glycopeptide that could be proposed as an alternative to other recommended drugs for CDI. In our case series, teicoplanin seems to be an effective therapy as a first-line regimen for CDI in geriatrics. Such treatment has good acceptability in geriatrics, considering it can be taken orally twice a day.

Geriatric factors analyses from FFCD 2001-02 phase III study of first-line chemotherapy for elderly metastatic colorectal cancer patients.

AIM: Several predictors of metastatic colorectal cancer (mCRC) outcomes have been described. Specific geriatric characteristics could be of interest to determine prognosis. METHOD: Elderly patients (75+) with previously untreated mCRC were randomly assigned to receive infusional 5-fluorouracil-based chemotherapy, either alone (FU) or in combination with irinotecan (IRI). Geriatric evaluations were included as an optional procedure. The predictive value of geriatric parameters was determined for the objective response rate (ORR), progression-free survival (PFS) and overall survival (OS). RESULTS: From June 2003 to May 2010, the FFCD 2001-02 randomised trial enrolled 282 patients. A baseline geriatric evaluation was done in 123 patients; 62 allocated to the FU arm and 61 to the IRI arm. The baseline Charlson index was ≤1 in 75%, Mini-Mental State Examination was ≤27/30 in 31%, Geriatric Depression Scale was >2 in 10% and Instrumental Activities of Daily Living (IADL) was impaired in 34% of the patients. Multivariate analyses revealed that no geriatric parameter was predictive for ORR or PFS. Normal IADL was independently associated with better OS. The benefit of doublet chemotherapy on PFS differed in subgroups of patients ≤80 years, with unresected primary tumour, leucocytes >11,000 mm3 and carcinoembryonic antigen >2N. There was a trend towards better OS in patients with normal IADL. CONCLUSION: The autonomy score was an independent predictor for OS. A trend toward a better efficacy of doublet chemotherapy in some subgroups of patients was reported and should be further explored.

[Antibiotic prescription usage and assessment in geriatric patients]. / Usage et évaluation des prescriptions antibiotiques en gériatrie.

Due to the high risk of infection, the geriatric population is regularly subjected to antibiotics. Faced with bacterial resistance, particularly among elderly dependent patients, it is essential to promote proper use and correct prescription of antibiotics. A study evaluated antibiotic prescription in a geriatric hospital with 598 beds and highlighted the importance of collaboration between geriatricians and infectious disease specialists.

[A geriatrics unit with a 24 hour visiting policy]. / Une unité de gériatrie ouverte aux familles sans limitation d'horaires.

As hospitals' visiting times are extended, patients' families and friends are granted an ever more important place. The nursing team of an acute geriatrics unit open 24/7 examined the place and the role of patients' families and friends and their involvement in care.

[Representation and practice about "chimical restraints": qualitative study with 50 health worker]. / Interprétation et pratiques autour du terme "contention chimique" : étude qualitative auprès de 50 professionnels de santé.

The term "chemical restraints" seems to be used in medical practice, but does not have the same meaning for all French health care professionals. In available literature it is considered as use of psychotropic medications for behavioral disorders. We used qualitative research method based on semi-directive interviews, in order to better understand meaning of "chemical restraint" term for geriatric medical and paramedical personnel. This term is well understood, rarely used, wrong for some professional because "drugs do not hold". The term of "physical restraint" has a more tangible reality. The term of "sedation of psychocomportemental troubles" is more common and seems to have a less pejorative connotation. In practice chemical restraint may correspond to emergency use of benzodiazepines or neuroleptics by injection at doses leading to the patient's sedation without his consent.

[Urinary tract infections in the elderly]. / Les infections urinaires chez la personne âgée.

In the elderly, urinary tract infections are frequent. Diagnosis is not always evident because symptoms are often absent. In doubt, a urinary strip evaluation must be performed. Prevention begins with simple lifestyle and dietary rules, such as good voiding and adequate fluid intake. Asymptomatic bacteriuria is treated only in certain cases. Other urinary tract infections require antibiotics, which must be adapted to renal function.

Laparoscopy versus EVAR for the treatment of abdominal aortic aneurysms in the octogenarian.

BACKGROUND: Octogenarians are considered at high surgical risk for the treatment of abdominal aortic aneurysms (AAA). The laparoscopic aortic surgery (LAS) and the endovascular treatment (EVAR) are 2 minimum invasive techniques whose objective is to limit the operative traumatism. The objective of this study was to compare our results with short- and medium-term results with these 2 techniques in the octogenarians. METHODS: Between January 2002 and December 2012, the data of 674 operated consecutive AAA (315 LAS, 172 EVAR, and 187 open surgeries) were collected prospectively. Eighty-seven patients aged ≥80 years presenting a favorable anatomy were treated by LAS or EVAR. Twenty-five patients aged ≥85 years with a favorable anatomy were excluded because we generally did not propose LAS to them. Statistical analysis compared the demographic data and the results of the 2 groups. The principal criterion of judgment (PCJ) was the combined rate of mortality and severe systemic complications (MSSC) at 30 days. An uni/multivariate model was used to determine the factors associated with the occurrence of the PCJ. The data were expressed as means and standard deviations. A P value ≤0.05 was considered significant. RESULTS: Sixty-two patients (90% men, age 81.8 ± 1.4 years) were included. There were 31 EVAR and 31 LAS. The 2 groups were comparable concerning the demographic data, the comorbidities, and the aneurysmal anatomies. There was a nonsignificant tendency to higher rates of mortality (9.7 vs. 3.2%, P = 0.3) and MSSC at 30 days (16.1 vs. 3.2%, P = 0.09) in the LAS group. During the operation, LAS was associated with a longer operative time (289 ± 85 vs. 152 ± 57 min, P < 0.0001), more blood losses (1,073 ± 763 vs. 148 ± 194 mL, P < 0.0001), and more transfusions (2.0 ± 3.0 vs. 0.9 ± 1.1 units, P = 0.048). In the postoperative period, the patients operated by LAS had longer reanimation and hospitalization stays (12.9 ± 13.1 vs. 7.0 ± 2.5 days, P = 0.02; and 3.3 ± 4.4 vs. 0.6 ± 0.7 days, P = 0.002; respectively). However, in multivariate analysis, an operative duration >300 min was the only variable associated with the PCJ (P = 0.05). With a follow-up of 9.0 ± 10.7 month, there were 2 reinterventions in the EVAR group, whereas with a follow-up of 38.0 ± 23.9 month, no reintervention was observed in the LAS group. CONCLUSIONS: In the short run, EVAR significantly reduces the operative traumatism in comparison with LAS in the octogenarian presenting an AAA with a favorable anatomy. However, the choice of the technique is not independently predictive of MSSC at 30 days. When a durable repair is desirable, LAS remains a possible option in the octogenarian with a good general condition presenting a favorable aneurysmal anatomy.
