Description and Durability of the Various Indirect Restoration Techniques in Molar-Incisor Hypomineralisation: A Systematic Review.

Molar-incisor hypomineralisation (MIH) is a qualitative defect of the enamel structure. Indirect restorations may represent the most suitable therapeutic solutions for patients presenting MIH with tooth restorative procedures. This systematic review aims to determine the feasibility of indirect restorations. MATERIALS AND METHODS: A systematic review has been performed and is reported following the PRISMA guidelines. It was performed on three databases (PubMed, Science Direct, and Google Scholar). Ten articles were included. RESULTS: Only two articles reported the use of CAD/CAM technologies, whereas the other eight preferred conventional registration and handmade stratification for ceramics. All indirect bonded restorations made of composite resins or ceramics had significant success rates. A temporary material was placed in most of the articles. There was no clear consensus for tissue conditioning before bonding. Depending on the authors and the articles, the follow-up period extended from 2 months to 6 years. CONCLUSIONS: The survival rate and the non-invasive procedures of indirect restorations are two main arguments that can help dental practitioners in daily practice. Development of CAD/ CAM technologies adds new perspectives in the registration, the design and production. However, more clinical trials are needed to confirm the conclusions.

Effects of postpartum milking strategy on plasma mineral concentrations and colostrum, transition milk, and milk yield and composition in multiparous dairy cows.

The effects of postpartum milking strategy on plasma mineral concentrations, blood ß-hydroxybutyrate (BHB) concentration, and colostrum, transition milk, and first monthly test milk yield and composition were evaluated in 90 multiparous Jersey and Jersey × Holstein crossbreed cows from a commercial farm. Before first postpartum milking, cows were randomly assigned to the following milking strategies, implemented during the first 2 d postpartum: twice-a-day milking (M2, standard industry practice, milking every 12 h; n = 22), once-a-day milking (M1, milking every 24 h; n = 24), restricted milking (MR, 3-L milking every 12 h; n = 21), and delayed milking (MD, no milking for the first 24 h, and milking every 12 h afterward; n = 23). Blood samples for total plasma Ca, P, and Mg determination were collected from enrollment every 4 h up to 48 h, and at 3 d in milk. Blood BHB concentration was determined at 3 and 11 d in milk. Colostrum and transition milk yields were recorded, and samples were collected at each study milking for IgG and somatic cell count (SCC) determinations. Information for first monthly test milk yield and composition was obtained from the Dairy Herd Improvement Association. Statistical analyses were conducted using generalized multiple linear and Poisson regressions with Dunnett adjustment and M2 as reference group for mean comparisons. Overall, plasma Ca concentration within 48 h after enrollment was higher for MD (2.17 mmol/L), tended to be higher for MR (2.15 mmol/L), and was similar for M1 (2.09 mmol/L) compared with M2 cows (2.06 mmol/L). No statistically significant differences compared with M2 cows were observed for plasma P and Mg concentrations. Colostrum and transition milk and total Ca harvested within 48 h after enrollment were lower for M1, MR, and MD compared with M2 cows. The MD strategy prevented harvesting colostrum with >50 g of IgG/L. No statistically significant effects were detected on plasma mineral concentrations at 3 DIM, blood BHB concentration, colostrum and transition milk SCC within 48 h after enrollment, or milk yield, energy-corrected milk yield, and SCC at first monthly test. Our results suggest that postpartum plasma Ca concentration may be influenced by postpartum milking strategy, without interfering with future milk yield and udder health. Further studies should evaluate whether the proposed milking strategies in early postpartum affect production, reproduction, or health.

Long-term follow-up of HIV-infected patients on dolutegravir monotherapy.

BACKGROUND: In recent years, dolutegravir monotherapy has been explored as a drug-reduced regimen for HIV patients. METHODS: This was a retrospective observational study, including patients virologically suppressed for ≥6 months, without previous virological failure (VF) under integrase inhibitors (INIs), who had been switched to dolutegravir monotherapy (50 mg/day). The primary aim was to report the proportion of VF at week 48 (W48) and week 96 (W96) of dolutegravir monotherapy. The evolution from baseline to W48 of residual viraemia on ultra-deep sequencing and HIV DNA was also evaluated. RESULTS: Sixty-one patients were included. Prior to switching to dolutegravir monotherapy, they had a median (IQR) of 15.4 (6.5-19.9) years of antiretroviral exposure, 5.8 (3.2-10.3) years of viral suppression and 687 (461-848) CD4+ cells/mm3. They remained on dolutegravir monotherapy for a median (IQR) of 100 (29-148) weeks. Forty-two out of 61 patients (68.9%) reached W48 and 32 out of 61 patients (52.5%) reached W96. VF occurred in three patients, with the emergence of INI resistance. VF occurred before W24 and in patients pre-exposed to INIs. At W48, the probability of VF (Kaplan-Meier analysis) was 5.6% (95% CI = 1.8%-16.4%). The same result was obtained at W96. Detectable residual viraemia did not increase and median HIV DNA did not change significantly (2.4 log/106 cells at baseline and 2.3 log/106 cells at W48). Dolutegravir plasma concentration was above the IC90 in 41/41 samples, from 22 patients. CONCLUSIONS: Long-term follow-up showed a low risk of VF under dolutegravir monotherapy, in a selected population of patients with previous long-term virological suppression and low HIV reservoir.

Routine screening for HIV, hepatitis B virus and hepatitis C virus in individuals undergoing oral and maxillofacial surgery.

OBJECTIVES: Given the effectiveness of treatment of HIV, hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, there are considerable benefits associated with determining HIV/HBV/HCV status. We evaluated the feasibility and acceptability of systematic screening and subsequent care in an oral and maxillofacial surgery department. METHODS: The anaesthesiologists proposed screening for HIV, HBV and HCV to all individuals of unknown infection status undergoing surgery between 19 April 2016 and 19 April 2017. The endpoints were the rates of test offer, acceptance/refusal and new diagnoses. Seropositive individuals were referred to infectious disease specialists. Associations between age, sex or surgery type and test offer (eligible individuals) or acceptance/refusal (those offered testing) were investigated. RESULTS: Of the 1407 individuals attending the department, 1322 were eligible for inclusion in the study. Testing was proposed to 899 individuals [68%; 95% confidence interval (CI) 65-71%], 831 of whom accepted the offer (92.4%; 95% CI 90.5-94.1%). Results were obtained for 787 individuals (41 samples were uncollected and three were invalid). Age was the only factor associated with test offer in multivariable analysis [odds ratio (OR) 0.90; 95% CI 0.84-0.97, per additional 10 years], and no factor was associated with acceptance. Of the five, three and eight individuals testing positive for HIV, HBV and HCV, four, two and one patient, respectively, reported prior knowledge of seropositivity. The new diagnosis rate was 0.13% (95% CI 0-0.7%) for HIV and HBV, and 0.89% (95% CI 0.36-1.82%) for HCV [three positive polymerase chain reaction (PCR) tests]. All individuals newly diagnosed with HIV or HCV infection received specific antiviral treatment. CONCLUSIONS: Rates of screening offer and acceptance were high. Substantial screening resources are required to decrease the impact of the hidden epidemics of HIV, HBV and HCV infections.

Adult moyamoya angiopathy in Bourgogne-Franche-Comté: Epidemiology, diagnosis and management.

INTRODUCTION: Moyamoya angiopathy (MMA) is a progressive steno-occlusive disease of the distal internal carotid arteries mainly described in Asia. It induces the development of collateral vascular networks to reduce chronic cerebral hypoperfusion. Symptoms depend on the patient's age in Asia: children are at greater risk of transient or constituted ischemic events, whereas adults are more exposed to hemorrhagic stroke. Data from the literature seem to show that the pattern of MMA in western countries differs from that in Asia. MATERIAL AND METHODS: A retrospective study of patients with MMA was conducted in Bourgogne-Franche-Comté (mid-eastern France). Clinical data (symptoms, risk factors, age at diagnosis, number and timing of recurrences, type of treatment) as well as radiological data (angiographic findings, Suzuki's grade) were analyzed. RESULTS: Seventeen adult patients (9 men, 53%) were followed at the university hospitals of Besançon and Dijon from 2009 to 2016. Fourteen patients (83%) had bilateral disease. The mean age at diagnosis was 49 years (±16), 83% of the patients were Caucasian and 17% originated from Maghreb. Only 17% of the hemispheres had a hemorrhagic form. Ischemic form was more frequent before diagnosis with transient ischemic attack (24% of patients) and stroke (83% of patients). With medical treatment, 9 patients suffered from stroke recurrence (53% of patients) with an average delay of 22.7±34 months. Three patients (18%) had combined surgical management by encephelo-synangiosis and superficial temporal artery-to-middle cerebral artery (STA-MCA) anastomosis, without symptom recurrence after treatment with an average follow up of 14 months. CONCLUSION: MMA remains a rare cerebrovascular disease in Europe and requires multidisciplinary care. Epidemiological analysis showed differences with the Asian population, especially the predominance of ischemic forms in adults.

Efficacy of colostrum replacer versus maternal colostrum on immunological status, health, and growth of preweaned dairy calves.

Commercially available colostrum replacers (CR) are commonly used when maternal colostrum (MC) is unavailable, for managerial convenience, to ensure quality consistency at first feeding, or in disease control and eradication programs. The objective of this study was to determine the efficacy of feeding First Day Formula (Accelerated Genetics, Baraboo, WI) CR versus pooled MC on immunological status, growth, and health of preweaned dairy calves. A total of 1,220 Jersey and Jersey × Holstein calves born on a California Central Valley dairy farm were assigned after birth to receive either CR or MC following a systematic allocation procedure. Calves assigned to MC were tube fed 2.8 L of MC, and calves assigned to CR were tube fed a total of 500 g of CR (150 g of immunoglobulin G; IgG) mixed into 1.9 L of water at 1 h ± 5 min after the calf was born. A subset of calves was selected for passive transfer (n = 592) and growth (n = 268) analyses. Although both coliform count and total bacteria count were low for MC and CR fed to calves during the study, the predicted probability of calves receiving contaminated liquid feed (coliform count >10,000 cfu/mL) at first feeding was reduced for calves fed CR (1.5%) compared with calves fed MC (6.1%). The mean blood concentration of IgG was lower for calves fed CR than for calves fed MC (19.6 vs. 23.4 mg/mL). However, the apparent efficiency of absorption of IgG did not differ between treatments (34.4 and 35.9% for CR and MC, respectively). Total proteins were lower in calves fed CR compared with MC at 24 h (5.16 vs. 5.84 g/dL, respectively). Calves fed CR were 1.5 kg lighter at weaning and gained 0.03 kg less per day (0.30 vs. 0.33 kg/d, respectively) than calves fed MC before weaning. Height at weaning did not differ between the 2 treatment groups. Calves fed CR tended to have a higher predicted probability of not being treated for diarrhea than calves fed MC (0.142 vs. 0.110, respectively). However, when the disease was present, CR had a higher number of treatment days compared with MC (11.6 vs. 10.8 d, respectively). The hazard ratio of dying did not differ between MC and CR; however, CR calves had a numerically higher risk (hazard ratio = 1.347) of dying compared with calves that received MC. In conclusion, IgG absorption and serum concentration of calves were adequate when calves were fed either CR or MC. The CR-fed calves had a lower probability of receiving contaminated liquid feed and performed similar in terms of health compared with calves receiving high-quality MC, although they were slightly lighter at weaning. Therefore, the CR evaluated in this study is a valid alternative to high-quality (>50 mg of IgG/mL) MC.

Pain after stroke: A review.

Pain after stroke (PAS) is a common clinical problem that is both underdiagnosed and undertreated. Yet, it induces depression and cognitive troubles, and impairs quality of life. To provide tools for practitioners, this report describes the most common PAS syndromes, including central post-stroke pain, spasticity and contractures, shoulder pain and complex regional pain syndromes, as well as headache and chondrocalcinosis, along with their risk factors, their prevention and their specific treatments. In addition, to ensure that the compulsory post-stroke clinical assessment in France is optimal, it is recommended that clinicians be trained in how to diagnose and treat PAS, and even to prevent it by early identification of at-risk patients, with the aim to improve patients' motor and cognitive functions and quality of life.

Associated arterial and venous cerebral manifestations in Behçet's disease.

Behçet's disease is a rare multisystemic vasculitis with an etiology that is still unknown. Neurological manifestations may be seen in approximately 5-15% of patients, and both parenchymal and extraparenchymal neurological involvement has been described. When cerebral venous thrombosis (CVT) is the main extraparenchymal manifestation of Behçet's disease, the condition is then dubbed "angio-Behçet's syndrome". However, arterial involvement is extremely rare, with only one reported case of vasculo-neuro-Behçet's disease, characterized by both venous and intracranial arterial involvement - until now. This report is of two patients diagnosed with Behçet's disease characterized by the concomitant presence of both cerebral arterial manifestations and CVT.

High-contrast 10 fs OPCPA-based front end for multi-PW laser chains.

Applications using multi-PW lasers necessitate high temporal pulse quality with a tremendous contrast ratio (CR). The first crucial prerequisite to achieve multi-PW peak power is the generation of ultrashort pulses with good spectral phase quality. Second, to avoid any deleterious pre-ionization effect on targets, nanosecond contrast better than 1012 is also targeted. In the framework of the Apollon 10 PW French laser program, we present a high-contrast 10 fs front-end design study to inject highly energetic Ti:sapphire PW lasers. The CR has been measured and analyzed in different time ranges highlighting the different major contributions for each scale.

Enhanced recovery ERAS for elderly: a safe and beneficial pathway in colorectal surgery.

BACKGROUND: Enhanced recovery after surgery (ERAS) pathway includes recovery goals requiring active participation of the patients; this may be perceived as "aggressive" care in older patients. The aim of the present study was to assess whether ERAS was feasible and beneficial in older patients. METHODS: Since June 2011, all consecutive colorectal patients were included in an ERAS pathway and documented in a dedicated prospective database. This retrospective analysis included 513 patients, 311 younger patients (<70 years) and 202 older patients (≥70 years). Outcomes were adherence to the ERAS pathway, functional recovery, postoperative complications, and hospital stay. RESULTS: Older patients had significantly more diabetes, malignancies, cardiac, and respiratory co-morbidities; both groups underwent similar surgical procedures. Overall adherence to the ERAS pathway was in median 78 % in younger and 74 % in older patients (P = 0.86). In older patients, urinary drains were kept longer (P = 0.001), and oral fluid intake was reduced from day 0 to day 3 (P < 0.001). There were no differences in mobilization and intake of nutritional supplements. Postoperative complications were similar for both comparative groups (51.5 vs. 46.6 %, P = 0.32). Median length of stay was 7 days (IQR 5-13) in older patients vs. 6 days (IQR 4-10) in the younger group (P = 0.001). CONCLUSION: Adherence to the ERAS pathway was equally high in older patients. Despite more co-morbidities, older patients did not experience more complications. Recovery was similar and hospital stay was only 1 day longer than in younger patients. ERAS pathway is of value for all patients and does not need any adaptation for the elderly.

Dolutegravir as monotherapy in HIV-1-infected individuals with suppressed HIV viraemia.

BACKGROUND: Reducing drug burden is a key challenge for achieving lifelong suppressive HIV therapy. Dolutegravir, with a high potency, long half-life and high genetic barrier, offers potential for monotherapy. METHODS: This observational single-centre study enrolled all patients with HIV RNA (viral load) <50 copies/mL for at least 12 months, with CD4 >350 cells/mm(3) and with no failure under integrase inhibitor therapy who had switched from suppressive ART to dolutegravir monotherapy (50 mg/day). Primary outcome was proportion of patients with viral load <50 copies/mL at week 24. RESULTS: Twenty-eight patients treated for a median ART duration of 17 years (IQR 11-20), virally suppressed for a median of 79 months (IQR 42-95) and with a median CD4 count of 624 cells/mm(3) (IQR 524-761), were enrolled. Baseline ART consisted of a three-drug (n = 10), two-drug (n = 10) or single-drug (n = 8) regimen with integrase inhibitor exposure in 13 patients. The proportion of patients maintaining viral load <50 copies/mL was 96% (95% CI 79%-100%) at week 4, 100% (95% CI = 85%-100%) at week 8, 93% (95% CI 76%-99%) at week 12 and 92% (75-99) at week 24. Three patients (3.70%; 95% CI 3.4%-10.8%) with prior integrase inhibitor experience had HIV RNA rebound with the presence of resistance mutations. Genotyping of HIV DNA using the Sanger method or ultradeep sequencing showed no integrase inhibitor resistance-associated mutations (RAMs) except for the mutation 74I in a patient on a suppressive elvitegravir regimen. The median within- and between-subject variability of dolutegravir C24 was 25% and 34%, respectively. Nine patients with a year of follow-up remained virally suppressed. CONCLUSIONS: Dolutegravir has the potency to be further investigated as a single ART in randomized studies, particularly in patients with no prior exposure to integrase inhibitors.

[Updates on prevention and treatment of melanoma: Pharmacist involvements and challenges]. / Actualités dans la prévention et la prise en charge du mélanome : implications et enjeux pour le pharmacien.

Melanoma is a skin cancer that represents an actual public health problem. Its incidence is increasing every year. Environmental risk factors have been clearly identified. Early diagnosis of a suspicious skin lesion should be possible by any health professionals because the prognosis is correlated with the evolution of the disease and the presence of metastases. The advent of new therapies in metastatic forms with the development of immunotherapies and kinases inhibitors has significantly changed the management of this disease. New therapies are available in retail pharmacies and involve health professionals out of the hospital. This article is intended for community and hospital pharmacists and summarizes recommendations for primary and secondary prevention. It updates on new targeted therapies. It wants to give advices to the community pharmacists about the effective use of those treatments for melanoma.

[Moyamoya disease: Diagnosis, clinical features, evolution and treatment in 10 patients]. / Maladie de Moyamoya : aspects diagnostiques, cliniques, évolutifs et thérapeutiques chez 10 patients.

INTRODUCTION: Moyamoya disease is a rare chronic cerebrovascular disease. The objective of this article is to report the different clinical and radiological presentations and describe treatments and clinical course of this disease. METHODS: We searched for patients with Moyamoya disease diagnosed at a French university hospital. The diagnosis was based on arteriographic records showing uni- or bilateral stenosis of distal intracranial internal carotid arteries or middle cerebral arteries associated with a classic collateral network imparting a puff of smoke aspect. Data about clinical and radiological symptoms were analyzed for all identified patients. RESULTS: Ten patients were recorded between 2009 and 2014 including one child and nine adults. The initial presentation was intracerebral hemorrhage in two patients, ischemic stroke in six, and either exercice-related transient ischemic attacks or syncope in two. Recurrent events were noted in four patients. Four patients had one or several recurrent vascular events. Eight patients were given medical treatment and none underwent surgery. Secondary Moyamoya syndrome was suspected in two patients, all the others one were considered idiopathic. CONCLUSION: Moyamoya disease is a rare but potentially severe illness. The initial presentation is more frequently an ischemic stroke; recurrences are frequent. The diagnosis is based on arteriography, which is also recommended to search for a cause.

[Functional reconstruction of the forearm by composite free flap of fibula and soleus reinnervated. About a clinical case]. / Reconstruction fonctionnelle de l'avant-bras par lambeau libre composite de fibula et de soléaire ré-innervé. À propos d'un cas.

SUBJECT: We present the case of a forearm functional reconstruction of composite fibula free flap. This is a complex forearm trauma by crushing in a 24-year-old patient. The assessment of the lesions showed a bone defect of 15cm radial and ulnar diaphysis, a muscular defect of the posterior compartment of the forearm and a large skin defect next. The radial pedicle was also injured. METHODS: At 48hours, we conducted a reconstruction by free fibular flap and soleus muscle. The fibula osteosynthesys was performed between the proximal ulna and radius distally. The nerve of the soleus muscle was anastomosed to a branch of the posterior interosseous nerve and tendons of the extensor muscles of the wrist and fingers were sutured to the distal portion of the transferred muscle. RESULTS: At 6 months, bone healing is achieved. Soleus muscle contracts and the strength of the extensor muscles of the fingers and wrist has been listed 4. Joint amplitudes of -20°/75° for the wrist, complete for the long fingers and the elbow. The aftermath of the donor site is minimal. CONCLUSION: Reconstruction by free fibular flap and reinnervated soleus muscle is often cited in the literature but few cases are described. It is for us, the best therapeutic solution for this type of injury. It restores muscle function satisfactorily all ensuring high quality coverage defect of the forearm.

[Anaplasic large cell lymphoma after breast prosthesis removal: about a case]. / À propos d'un cas de lymphome anaplasique à grandes cellules diagnostiqué après explantation de prothèse mammaire.

There has recently been a new controversy about the appearance of a particular histological type of lymphoma, anaplasic large cell lymphoma, in patients carriers of breast implants, with no causal link has been established for the moment. We report the case of a patient of 67 years old with recurrent effusion breast after explantation of breast prosthesis. The diagnosis of anaplasic large cell lymphoma was made after histological examination of the entire peri-prosthetic capsule after removal of most common diagnoses such as infection. Taking in hematological load was then established with the administration of chemotherapy to complete remission. All peri-prosthetic recurrent effusion should suggest the diagnosis of anaplasic large cell lymphoma, the definitive diagnosis requires the completion of a total capsulectomy with histological examination of the entire capsule.

Rapid plasma viral suppression in naive HIV-infected patients with high CD4 cells and low viraemia initiating a dual nucleoside reverse transcriptase inhibitor strategy: a proof-of-concept study.

OBJECTIVES: To evaluate whether a dual nucleoside reverse transcriptase inhibitor (NRTI) strategy can control HIV replication in antiviral therapy (ART)-naive HIV-infected patients with a high CD4 cell count and a low viral load (VL). METHODS: This observational study included all HIV-infected treatment-naive patients with a CD4 cell count >300 cells/mm(3), a plasma HIV RNA between 1000 copies/mL and 30,000 copies/mL and wild-type virus who initiated dual NRTI ART between January 2008 and December 2012. HIV RNA and CD4 cell count were assessed at Day 0, Week (W) 4, W12, W24 and W48. The primary endpoint was the proportion of patients with a plasma VL (pVL) <50 copies/mL at W24. RESULTS: Twenty patients were included. The median (IQR) baseline characteristics were: time since HIV diagnosis, 25 months (8-66 months); CD4 cell count, 592 cells/mm(3) (405-798 cells/mm(3)); HIV RNA, 10,395 copies/mL (4106-16,566 copies/mL); and HIV DNA, 464 copies/10(6) peripheral blood mononuclear cells (195-1168 copies/10(6) PBMC). Nineteen patients received tenofovir/emtricitabine and one patient received abacavir/lamivudine. At W12, 88% of the patients with available data (n = 16/18, 95% CI 0.65-0.99) had a pVL <50 copies/mL. Overall, the proportion of patients with a pVL <50 copies/mL was 100% (n = 20/20, 95% CI 0.83-1.0) at W24 and 95% (n = 18/19, 95% CI 0.74-0.99) at W48 (with one patient lost to follow-up and one patient with poor treatment compliance). The median increase in CD4 cells was 83 cells/mm(3) (40-310 cells/mm(3)). There was no discontinuation of antiretroviral therapy for any reason such as lack of efficacy or toxicity. CONCLUSIONS: This pilot study suggests that, in patients with a high CD4 cell count and a low VL, a dual NRTI strategy may represent a potentially effective treatment strategy to control HIV replication. This needs to be confirmed in larger controlled clinical studies.

Efficacy of raltegravir switching strategies in HIV-infected patients with suppressed viraemia according to the genotypic sensitivity score.

BACKGROUND AND PURPOSE: The lack of antiretroviral (ARV) backbone activity associated with raltegravir has been proposed as the main explanation for virological relapse observed in patients with undetectable viraemia who are switched from a ritonavir-boosted protease inhibitor (PI) to raltegravir. However ARV activity remains difficult to assess in this context. The aim of our study was to precisely assess the ARV backbone activity in patients with undetectable viraemia who underwent raltegravir switching strategies and to evaluate the efficacy of such switching strategies based on the genotypic sensitivity score (GSS). METHODS: Patients with a plasma human immunodeficiency virus type 1 (HIV-1) RNA level of <50 copies/mL on a stable two ARV-class regimen were enrolled if they switched one of their ARV drugs to raltegravir 400 mg twice daily. The GSS was calculated using a genotyping test performed on the HIV-1 RNA of the last plasma measurement with a HIV-1 RNA level of >50 copies/mL before the switch and on the results of all previous genotyping tests. The primary endpoint was the proportion of patients with a plasma HIV-1 RNA level of <50 copies/mL at week 24. RESULTS: Fifty-six patients were enrolled in this study. The proportion of patients with a plasma HIV-1 RNA level of <50 copies/mL at week 24 was 92.9 % (range 83.0-97.2 %) in the intent-to-treat analysis and 98.1 % (90.0-99.7 %) in per-protocol analysis. When the backbone was fully active, the proportion was 100.0 % (86.7-100.0 %) at week 24 and week 48 in the per-protocol analysis. We observed a decrease in plasma total cholesterol and triglycerides of -12.7 % (p = 0.005) and -26.5 % (p = 0.001), respectively. CONCLUSIONS: Raltegravir switching strategies are effective when the associated backbone is fully active according to the GSS. In the context of undetectable viraemia, where ARV activity remains difficult to assess, the determination of the GSS requires the entire ARV history of the patient and all previous HIV-RNA genotyping test results.

Blood calcium dynamics after prophylactic treatment of subclinical hypocalcemia with oral or intravenous calcium.

Total serum Ca dynamics and urine pH levels were evaluated after prophylactic treatment of subclinical hypocalcemia after parturition in 33 multiparous Jersey × Holstein crossbreed cows. Cows were blocked according to their calcemic status at the time of treatment [normocalcemic (8.0-9.9 mg/dL; n = 15) or hypocalcemic (5.0-7.9 mg/dL; n = 18)] and randomly assigned to 1 of 3 treatments: control [no Ca supplementation (n = 11)]; intravenous Ca [Ca-IV (n = 11), 500 mL of 23% calcium gluconate (10.7 g of Ca and 17.5 g of boric acid as a solubilizing agent; Durvet, Blue Springs, MO)]; or oral Ca [Ca-Oral (n = 11), 1 oral bolus (Bovikalc bolus, Boehringer Ingelheim, St. Joseph, MO) containing CaCl2 and CaSO4 (43 g of Ca) 2 times 12h apart]. Total serum Ca levels were evaluated at 0, 1, 2, 4, 8, 12, 16, 20, 24, 36, and 48 h, and urine pH was evaluated at 0, 1, 12, 24, 36, and 4 8h after treatment initiation. Total serum Ca levels were higher for Ca-IV than for control and Ca-Oral cows at 1, 2, and 4h after treatment initiation, but lower than Ca-Oral cows at 20, 24, and 36 h and lower than control cows at 36 and 48 h. At 1h after treatment initiation, when serum Ca levels for Ca-IV cows peaked (11.4 mg/dL), a greater proportion of Ca-IV (n = 8) cows had total serum Ca levels >10mg/dL than control (n = 0) and Ca-Oral (n = 1) cows. At 24h after treatment initiation, when Ca-IV cows reached the total serum Ca nadir (6.4 mg/dL), a greater proportion of Ca-IV (n = 10) cows had serum Ca levels <8 mg/dL than control (n = 5) and Ca-Oral (n = 2) cows. Treatment, time, and treatment × time interaction were significant for urine pH. Mean urine pH was lower for Ca-Oral cows (6.69) than for control (7.52) and Ca-IV (7.19) cows. Urine pH levels at 1h after treatment were lower for Ca-IV cows compared with both control and Ca-Oral cows, a finding likely associated with the iatrogenic administration of boric acid added as a solubilizing agent of the intravenous Ca solution used. At 12, 24, and 36 h, urine pH levels were lower for Ca-Oral cows compared with both control and Ca-IV cows. This was expected because the oral Ca supplementation used (Bovikalc) is designed as an acidifying agent. Wide fluctuations in blood Ca were observed after prophylactic intravenous Ca supplementation. The implications for milk production and animal health, if any, of these transient changes in total serum Ca have yet to be evaluated.

[Enhanced Recovery After Surgery--optimal management of the surgical patient]. / Réhabilitation améliorée après chirurgie--L'ere de la prise en charge optimale du patient chirurgical.

Enhanced Recovery After Surgery (ERAS) is a multimodal, standardized and evidence-based perioperative care pathway. With ERAS, postoperative complications are significantly lowered, and, as a secondary effect, length of hospital stay and health cost are reduced. The patient recovers better and faster allowing to reduce in addition the workload of healthcare providers. Despite the hospital discharge occurs sooner, there is no increased charge of the outpatient care. ERAS can be safely applied to any patient by a tailored approach. The general practitioner plays an essential role in ERAS by assuring the continuity of the information and the follow-up of the patient.

Cost-effectiveness of the implementation of an enhanced recovery protocol for colorectal surgery.

BACKGROUND: Enhanced recovery protocols may reduce postoperative complications and length of hospital stay. However, the implementation of these protocols requires time and financial investment. This study evaluated the cost-effectiveness of enhanced recovery implementation. METHODS: The first 50 consecutive patients treated during implementation of an enhanced recovery programme were compared with 50 consecutive patients treated in the year before its introduction. The enhanced recovery protocol principally implemented preoperative counselling, reduced preoperative fasting, preoperative carbohydrate loading, avoidance of premedication, optimized fluid balance, standardized postoperative analgesia, use of a no-drain policy, as well as early nutrition and mobilization. Length of stay, readmissions and complications within 30 days were compared. A cost-minimization analysis was performed. RESULTS: Hospital stay was significantly shorter in the enhanced recovery group: median 7 (interquartile range 5-12) versus 10 (7-18) days (P = 0·003); two patients were readmitted in each group. The rate of severe complications was lower in the enhanced recovery group (12 versus 20 per cent), but there was no difference in overall morbidity. The mean saving per patient in the enhanced recovery group was €1651. CONCLUSION: Enhanced recovery is cost-effective, with savings evident even in the initial implementation period.
