Exploring the role of ex vivo metabolism on blood and plasma measurements of oxytocin among women in the third stage of labour: A post hoc study. Br J Clin Pharmacol 2023; 89:3669-3680. [PMID: 37522415 DOI: 10.1111/bcp.15865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 07/11/2023] [Accepted: 07/13/2023] [Indexed: 08/01/2023] Open
Abstract
AIMS To examine the role of ex vivo oxytocin metabolism in post-dose peptide measurements. METHODS The stability of oxytocin (Study 1) and oxytocinase activity (Study 2) in late-stage pregnancy blood was quantified using liquid-chromatography tandem mass-spectrometry (LC-MS/MS) and a fluorogenic assay, respectively. Analyses were conducted using blood from pregnant women (>36 weeks gestation) evaluated in lithium heparin (LH), ethylenediaminetetraacetic acid (EDTA) and BD P100 blood collection tubes with or without protease inhibitors. In addition, plasma oxytocin concentrations following administration of oxytocin 240 IU inhaled, 5 IU intravenous or 10 IU intramuscular in women in third stage of labour (TSL) were analysed using enzyme-linked immunosorbent assay (ELISA) and LC-MS/MS to understand how quantified peptide concentrations differ between these analytical methods (Study 3). RESULTS Study 1: Oxytocin was stable in blood collected into EDTA tubes with or without protease inhibitors but not in LH tubes. Study 2: Blood collected into all EDTA-containing collection tubes led to near-complete inhibition of oxytocinase (≤100 min). In plasma, a 35% reduction in oxytocinase activity was observed in LH tubes with EDTA added. In plasma from late-stage pregnancy compared to nonpregnant participants, the oxytocinase activity was approximately 11-fold higher. Study 3: Plasma oxytocin concentrations from nonpregnant or women in TSL following exogenous oxytocin administration were ≤33 times higher when analysed using ELISA vs. LC-MS/MS methods. CONCLUSIONS Collection of blood from late-stage pregnant women into tubes containing EDTA inhibits oxytocinase effectively stabilizing oxytocin, suggesting low concentrations of oxytocin after dose administration reflect rapid in vivo metabolism.

Pharmacokinetics and safety of inhaled oxytocin compared with intramuscular oxytocin in women in the third stage of labour: A randomized open-label study. Br J Clin Pharmacol 2023; 89:3681-3689. [PMID: 37485589 DOI: 10.1111/bcp.15860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 06/20/2023] [Accepted: 06/30/2023] [Indexed: 07/25/2023] Open
Abstract
AIMS To compare pharmacokinetics (PK) and safety of heat-stable inhaled (IH) oxytocin with intramuscular (IM) oxytocin in women in third stage of labour (TSL), the primary endpoint being PK profiles of oxytocin IH and secondary endpoint of safety. METHODS A phase 1, randomized, cross-over study was undertaken in 2 UK and 1 Australian centres. Subjects were recruited into 2 groups: Group 1, women in TSL; Group 2, nonpregnant women of childbearing potential (Cohort A, combined oral contraception; Cohort B, nonhormonal contraception). Participants were randomized 1:1 to: Group 1, oxytocin 10 IU (17 μg) IM or oxytocin 240 IU (400 μg) IH immediately after delivery; Group 2, oxytocin 5 IU (8.5 μg) intravenously and oxytocin 240 IU (400 μg) IH at 2 separate dosing sessions. RESULTS Participants were recruited between 23 November 2016 to 4 March 2019. In Group 1, 17 participants were randomized; received either IH (n = 9) or IM (n = 8) oxytocin. After IH and IM administration, most plasma oxytocin concentrations were below quantification limits (2 pg/mL). In Group 2 (n = 14), oxytocin IH concentrations remained quantifiable ≤3 h postdose. Adverse events were reported in both groups, with no deaths reported: Group 1, IH n = 3 (33%) and IM n = 2 (25%); Group 2, n = 14 (100%). CONCLUSION Safety profiles of oxytocin IH and IM were similar. However, PK profiles could not be established for oxytocin IH or IM in women in TSL, despite using a highly sensitive and specific assay.

A physiological approach to renal clearance: From premature neonates to adults. Br J Clin Pharmacol 2023. [PMID: 38031322 DOI: 10.1111/bcp.15978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 11/13/2023] [Accepted: 11/23/2023] [Indexed: 12/01/2023] Open
Abstract
AIMS We propose using glomerular filtration rate (GFR) as the physiological basis for distinguishing components of renal clearance. METHODS Gentamicin, amikacin and vancomycin are thought to be predominantly excreted by the kidneys. A mixed-effects joint model of the pharmacokinetics of these drugs was developed, with a wide dispersion of weight, age and serum creatinine. A dataset created from 18 sources resulted in 27,338 drug concentrations from 9,901 patients. Body size and composition, maturation and renal function were used to describe differences in drug clearance and volume of distribution. RESULTS This study demonstrates that GFR is a predictor of two distinct components of renal elimination clearance: (1) GFR clearance associated with normal GFR and (2) non-GFR clearance not associated with normal GFR. All three drugs had GFR clearance estimated as a drug-specific percentage of normal GFR (gentamicin 39%, amikacin 90% and vancomycin 57%). The total clearance (sum of GFR and non-GFR clearance), standardized to 70 kg total body mass, 176 cm, male, renal function 1, was 5.58 L/h (95% confidence interval [CI] 5.50-5.69) (gentamicin), 7.77 L/h (95% CI 7.26-8.19) (amikacin) and 4.70 L/h (95% CI 4.61-4.80) (vancomycin). CONCLUSIONS GFR provides a physiological basis for renal drug elimination. It has been used to distinguish two elimination components. This physiological approach has been applied to describe clearance and volume of distribution from premature neonates to elderly adults with a wide dispersion of size, body composition and renal function. Dose individualization has been implemented using target concentration intervention.

Medication-related Medical Emergency Team activations: a case review study of frequency and preventability. BMJ Qual Saf 2023; 32:214-224. [PMID: 35790383 DOI: 10.1136/bmjqs-2021-014185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 06/08/2022] [Indexed: 11/04/2022]
Abstract
OBJECTIVES Despite recognition of clinical deterioration and medication-related harm as patient safety risks, the frequency of medication-related Rapid Response System activations is undefined. We aimed to estimate the incidence and preventability of medication-related Medical Emergency Team (MET) activations and describe the associated adverse medication events. METHODS A case review study of consecutive MET activations at two acute, academic teaching hospitals in Melbourne, Australia with mature Rapid Response Systems was conducted. All MET activations during a 3-week study period were assessed for a medication cause including identification of the contributing adverse medication event and its preventability, using validated tools and recognised classification systems. RESULTS There were 9439 admissions and 628 MET activations during the study period. Of these, 146 (23.2%) MET activations were medication related: an incidence of 15.5 medication-related MET activation per 1000 admissions. Medication-related MET activations occurred a median of 46.6 hours earlier (IQR 22-165) in an admission than non-medication-related activations (p=0.001). Furthermore, this group also had more repeat MET activations during their admission (p=0.021, OR=1.68, 95% CI 1.09 to 2.59). A total of 92 of 146 (63%) medication-related MET activations were potentially preventable. Tachycardia due to omission of beta-blocking agents (10.9%, n=10 of 92) and hypotension due to cumulative toxicity (9.8%, n=9 of 92) or inappropriate use (10.9%, n=10 of 92) of antihypertensives were the most common adverse medication events leading to potentially preventable medication-related MET activations. CONCLUSIONS Medications contributed to almost a quarter of MET activations, often early in a patient's admission. One in seven MET activations were due to potentially preventable adverse medication events. The most common of these were omission of beta-blockers and clinically inappropriate antihypertensive use. Strategies to prevent these events would increase patient safety and reduce burden on the MET.

Enhanced primary care after hospitalization: General practitioner, pharmacist and patient feedback from the REMAIN HOME trial. Res Social Adm Pharm 2023; 19:510-516. [PMID: 36261303 DOI: 10.1016/j.sapharm.2022.09.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 08/30/2022] [Accepted: 09/26/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND Pharmacist and general practitioner (GP) collaborative models of care are continuing to evolve in the Australian primary care setting. The REMAIN HOME study investigated whether a pharmacist integrated into 14 different primary care teams in general practice (the "practice pharmacist model") reduces readmission to hospital for patients prescribed five or more long term medicines or high risk comorbidities. The aim of this paper is to describe the attitudes of GPs, patients, and practice pharmacists towards this model of pharmacist and GP collaboration. METHODS To explore the views and opinions about the model of care (pharmacist integration into general practice), participating GPs were invited to complete a survey that included the 13-item validated Attitudes Toward Collaboration Instrument for GPs (ATCI-GP) one month after the pharmacist had been integrated into the practice. Survey instruments were also created for patients and pharmacist participating in the intervention. These were deployed after the initial consultation and at the end of the intervention period respectively, to elicit each stakeholders' views and experiences of the service. Data were analysed using descriptive statistics. RESULTS In total, 48 GPs, 43/101 patients (43%) and 11/13 practice pharmacists (85%) completed the survey. The majority of GPs strongly agreed or agreed with all statements of the ATCI-GP, indicating support for the practice-integrated pharmacist model. Most patients agreed that there was a role for a pharmacist in their general practice (n = 28, 76%), and that they would like to see the pharmacist again (n = 34, 79%). Pharmacists indicated that they enjoyed the role (n = 11, 91%) and found the position professionally satisfying (n = 9, 82%). Most pharmacists agreed that co-location (inside the general practice itself, rather than in a co-located pharmacy) was beneficial (n = 8, 73%) and all pharmacists (100%) acknowledged the benefits of having access to patient medical records. Free text comments from GPs were enthusiastic overall, although some concerns about the financial viability of the model in the current setting were raised. The primary limitation of the study is the anonymous nature of the survey, meaning clustering of responses across the 14 sites could not be determined. CONCLUSIONS A practice pharmacist model of care in the Australian primary care setting appears to be accepted by GPs, patients and practice pharmacists and provides promising evidence that this model of care is likely to be well accepted if implemented more broadly in the Australian healthcare setting, provided that it can be appropriately remunerated.

Everolimus Based Immunosuppression Strategies in Adult Lung Transplant Recipients: Calcineurin Inhibitor Minimization Versus Calcineurin Inhibitor Elimination. Transpl Int 2023; 36:10704. [PMID: 36744051 PMCID: PMC9894878 DOI: 10.3389/ti.2023.10704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 01/02/2023] [Indexed: 01/21/2023]
Abstract
Everolimus (EVE) provides an alternative to maintenance immunosuppression when conventional immunosuppression cannot be tolerated. EVE can be utilized with a calcineurin inhibitor (CNI) minimization or elimination strategy. To date, clinical studies investigating EVE after lung transplant (LTx) have primarily focused on the minimization strategy to preserve renal function. The primary aim was to determine the preferred method of EVE utilization for lung transplant recipients (LTR). To undertake this aim, we compared the safety and efficacy outcomes of EVE as part of minimization and elimination immunosuppressant regimens. Single center retrospective study of 217 LTR initiated on EVE (120 CNI minimization and 97 CNI elimination). Survival outcomes were calculated from the date of EVE commencement. On multivariate analysis, LTR who received EVE as part of the CNI elimination strategy had poorer survival outcomes compared to the CNI minimization strategy [HR 1.61, 95% CI: 1.11-2.32, p=0.010]. Utilization of EVE for renal preservation was associated with improved survival compared to other indications [HR 0.64, 95% CI: 0.42-0.97, p=0.032]. EVE can be successfully utilized for maintenance immunosuppression post LTx, particularly for renal preservation. However, immunosuppressive regimens containing low dose CNI had superior survival outcomes, highlighting the importance of retaining a CNI wherever possible.

Rescue Everolimus Post Lung Transplantation is Not Associated With an Increased Incidence of CLAD or CLAD-Related Mortality. Transpl Int 2023; 36:10581. [PMID: 36824294 PMCID: PMC9942680 DOI: 10.3389/ti.2023.10581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 01/24/2023] [Indexed: 02/10/2023]
Abstract
Everolimus (EVE) has been used as a calcineurin inhibitor (CNI) minimization/ elimination agent or to augment immunosuppression in lung transplant recipients (LTR) with CNI-induced nephrotoxicity or neurotoxicity. The long-term evidence for survival and progression to chronic lung allograft dysfunction (CLAD) is lacking. The primary aim was to compare survival outcomes of LTR starting EVE-based immunosuppression with those remaining on CNI-based regimens. The secondary outcomes being time to CLAD, incidence of CLAD and the emergence of obstructive (BOS) or restrictive (RAS) phenotypes. Single center retrospective study of 91 LTR starting EVE-based immunosuppression matched 1:1 with LTR remaining on CNI-based immunosuppression. On multivariate analysis, compared to those remaining on CNI-based immunosuppression, starting EVE was not associated with poorer survival [HR 1.04, 95% CI: 0.67-1.61, p = 0.853], or a statistically significant faster time to CLAD [HR 1.34, 95% CI: 0.87-2.04, p = 0.182]. There was no difference in the emergence of CLAD (EVE, [n = 57, 62.6%] vs. CNI-based [n = 52, 57.1%], p = 0.41), or the incidence of BOS (p = 0.60) or RAS (p = 0.16) between the two groups. Introduction of EVE-based immunosuppression does not increase the risk of death or accelerate the progression to CLAD compared to CNI-based immunosuppression.

Abstract
Abstract
Background
Patients with cystic fibrosis (CF) experience recurrent bacterial pulmonary exacerbations. The management of these infections becomes increasingly complex due to decreased antimicrobial susceptibility and inadequate pharmacokinetic/pharmacodynamic (PK/PD) characterization of the most commonly used antimicrobial agents in this population.
Methods
One hundred fifty-five pediatric and adult participants receiving cefepime (n=82), meropenem (n=42), or piperacillin-tazobactam (n=31) were enrolled. Opportunistic blood samples were obtained during hospitalization. Population PK (PopPK) analysis was conducted using nonlinear mixed effects modeling in NONMEM, and clinical and demographic characteristics were evaluated as potential covariates. Monte Carlo simulations evaluated the probability of PK/PD target attainment (PTA) for different dosing regimens. Multiple targets, defined as percentage of a 24-h time period that the free drug concentration exceeds the MIC (fT > MIC), were selected based on prior studies of beta-lactam antibiotics.
Results
Preliminary PopPK modeling results show that lean body weight, creatinine clearance, daily dose, mode of administration (standard vs. extended infusion), and age affect PK parameters, with varying effects by drug. As anticipated, extended or continuous infusions resulted in higher PTA (Table 1). In the cefepime group, the 3-h infusion regimen achieved higher PTAs than the 0.5-h regimen across all age groups (Figure 1, Figure 2). Estimated breakpoints (in which ≥ 90% of patients are expected to achieve a PK/PD target) were 2-4 fold higher in pediatric participants receiving a 3-h infusion vs. 0.5-h infusion, based on age and target fT > MIC (Table 1). In the meropenem group, increased creatinine clearance led to reduced PTA, and in the piperacillin-tazobactam group, total daily dose and interval were the principal drivers of PTA. Table 1:Breakpoints (mg/L, highest minimum inhibitory concentration (MIC) with ≥ 90% PK target attainment) for different infusion durations, based on Monte Carlo simulations.Figure 1:Comparison of PTA between the two durations of infusion for 50 mg/kg (3 to 11 years) or 2 g (12 years and above) cefepime q8h at the target of 65% fT> MIC.Figure 2:Comparison of PTA between two durations of infusion for 50 mg/kg (3 to 11 years) or 2 g (12 years and above) cefepime q8h at the target of 100% fT> MIC.
Conclusion
To our knowledge, this is the largest PopPK study to date of these antimicrobials in individuals with CF. Clinicians should incorporate local antibiograms with these PopPK models to determine optimal dosing in patients with CF, since standard dosing regimens may fail to achieve specific PK/PD targets. This population may also benefit from beta-lactam therapeutic drug monitoring.

Abstract
INTRODUCTION AND AIMS The non-medical use of prescription stimulants such as methylphenidate, dexamphetamine and modafinil is increasing in popularity within tertiary academic settings. There is a paucity of information on awareness, attitudes, and acceptability by professionals of use in this context. This study aimed to investigate professionals' knowledge of and attitudes towards the use of cognitive enhancers (CEs) in academic settings, and their willingness to use a hypothetical CE. DESIGN AND METHODS A mail survey was sent to doctors, pharmacists, nurses, accountants and lawyers in New Zealand. These disciplines were chosen as they require professional registration to practice. The questionnaire comprised four sections: (1) demographics, (2) knowledge of CEs, (3) attitudes towards the use of CEs, and (4) willingness to use hypothetical CEs. RESULTS The response rate was 34.5% (414/1200). Overall, participants strongly disagreed that it was fair to allow university students to use CEs for cognitive enhancement (Mdn = 1, IQR: 1,3), or that it is ethical for students without a prescription to use cognitive enhancers for any reason (Mdn = 1, IQR: 1,2). Professions differed in their attitudes towards whether it is ethical for students without a prescription to use CEs for any reason (p = 0.001, H 31.527). DISCUSSION AND CONCLUSION Divergent views and lack of clear consensus within professions and between professionals on the use of CEs have the potential to influence both professionals and students as future professionals. These divergent views may stem from differences in the core values of self-identity as well as extrinsic factors of acceptability within the profession in balancing the elements of opportunity, fairness and authenticity in cognitive enhancement. Further research is required to inform the development of policy and guidelines that are congruent with all professions.

Systematic review and meta-analysis of oral paracetamol versus combination oral analgesics for acute musculoskeletal injuries. Emerg Med Australas 2020; 33:107-113. [PMID: 32864884 DOI: 10.1111/1742-6723.13596] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 07/05/2020] [Accepted: 07/08/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVE The aim of this systematic review and meta-analysis was to determine if a combination of analgesics conveys any significant clinical benefit over paracetamol alone in managing acute musculoskeletal injuries. METHODS Two reviewers independently searched MEDLINE (via PubMed), EMBASE and Cochrane electronic databases. Randomised controlled trials comparing paracetamol with paracetamol plus other oral analgesics in managing acute musculoskeletal injuries (e.g. sprains, contusions) were identified. Outcomes were reduction in pain score, adverse events and need for additional analgesia. Studies were critiqued using the Cochrane Risk of Bias Assessment Tool and data analysed using RevMAN meta-analysis software. RESULTS Six studies were included (n = 1254). No paediatric studies were identified. Five studies compared paracetamol to paracetamol plus NSAID. One study also included an opioid in the combination group. There was no clinically important difference between groups for reduction in pain score in the first 2 h, 24 h or 72 h. At 2 h the mean difference in reduction in pain score at rest on 100 mm VAS was 0.72 mm (-1.36, 2.79), P = 0.5. On activity it was -1.79 mm (-4.08, 0.49), P = 0.12. The risk of adverse events in ED was -0.00 (-0.04, 0.03). More patients receiving combination therapy required additional analgesia in the first 2 h: -0.03 (-0.06, -0.01), P = 0.01. CONCLUSION Paracetamol monotherapy is a reasonable first-line analgesic for acute musculoskeletal injuries as combining additional oral agents does not result in any significant additional analgesic effect.

Abstract
BACKGROUND We compared plasma and cerebrospinal fluid (CSF) pharmacokinetics of paracetamol after intravenous (IV) and oral administration to determine dosing regimens that optimize CSF concentrations. METHODS Twenty-one adult patients were assigned randomly to 1 g IV, 1 g oral or 1.5 g oral paracetamol. An IV cannula and lumbar intrathecal catheter were used to sample venous blood and CSF, respectively, over 6 hours. The plasma and CSF maximum concentrations (Cmax), times to maximum concentrations (Tmax), and area under the plasma and CSF concentration-time curves (AUCs) were calculated using noncompartmental techniques. Significance was defined by P < .0167 (Bonferroni correction for 3 comparisons for each parameter). Probability (X < Y) (p″) with Bonferroni corrected 95% confidence intervals (CIs) were calculated (CIs including 0.5 meet the null hypothesis). Results are presented as median (range) or p″ (CI). P values are listed as 1 g IV vs 1 g orally, 1 g IV vs 1.5 g orally and 1 g orally vs 1.5 g orally, respectively. RESULTS Wide variation in measured paracetamol concentrations was observed, especially in the oral groups. The median plasma Cmax in the 1 g IV group was significantly greater than the oral groups. In contrast, the median CSF Cmax was not different between groups. The median plasma Tmax in the 1 g IV group was 105 and 75 minutes earlier than in the 1 and 1.5 g oral groups. The median CSF Tmax was not significantly different between groups. The median plasma AUC (total) was not significantly different between groups; however, in the first hour, the median plasma AUC was significantly greater in the IV group than in the oral groups. In the second hour, there was no difference between groups. The median CSF AUC (total) did not significantly differ between groups; however, in the first hour, the median CSF AUC was significantly greater in the IV compared with the orally groups. In the second hour, there was no difference between groups. Our analysis indicated that the median Cmax, Tmax, and AUC values lacked precision because of small sample sizes. CONCLUSIONS Peak plasma concentrations were greater and reached earlier after IV than oral dosing. Evidence for differences in CSF Cmax and Tmax was lacking because of the small size of this study.

Abstract
INTRODUCTION A model of general practitioner (GP) and pharmacist collaboration in primary care may be an effective strategy to reduce medication-related problems and provide better support to patients after discharge. The aim of this study is to investigate whether a model of structured pharmacist and GP care reduces hospital readmissions in high-risk patients. METHODS AND ANALYSIS This protocol details a stepped-wedge, cluster-randomised trial that will recruit participants over 9 months with a 12-month follow-up. There will be 14 clusters each representing a different general practice medical centre. A total of 2240 participants will be recruited from hospital who attend an enrolled medical centre, take five or more long-term medicines or whose reason for admission was related to heart failure or chronic obstructive pulmonary disease.The intervention is a multifaceted service, involving a pharmacist integrated into a medical centre to assist patients after hospitalisation. Participants will meet with the practice pharmacist and their GP after discharge to review and reconcile their medicines and discuss changes made in hospital. The pharmacist will follow-up with the participant and liaise with other health professionals involved in the participant's care. The control will be usual care, which usually involves a patient self-organising a visit to their GP after hospital discharge.The primary outcome is the rate of unplanned, all-cause hospital readmissions over 12 months, which will be analysed using a mixed effects Poisson regression model with a random effect for cluster and a fixed effect to account for any temporal trend. A cost analysis will be undertaken to compare the healthcare costs associated with the intervention to those of usual care. ETHICS AND DISSEMINATION The study has received ethical approval (HREC/16/QRBW/410). The study findings will be disseminated through peer-reviewed publications, conferences and reports to key stakeholders. TRIAL REGISTRATION NUMBER ACTRN12616001627448.

Abstract
In Belgium, very few women give birth outside the delivery room. In the United Kingdom and in the Netherlands, they are more numerous. Several studies evaluated obstetric and neonatal outcomes of home births compared with hospital births. We selected seven recent and large studies (with cohorts of more than 5.000 women) using PubMed, Science Direct and Cochrane Database of Systematic Reviews. Several questions were examined. Is there any difference in maternal and neonatal outcomes depending on the intended place of birth? Does parity affect outcomes ? What are the characteristics of women who choose to deliver at home ? We conclude that giving birth at home improves obstetric outcomes but is riskier for the baby, especially for the first one. The women delivering at home are mainly white Europeans, between 25 and 35 years old, in a relationship, multiparous and wealthier. In order to avoid this increased risk for the baby while preserving the obstetric advantages, alongside birth centers offer an intermediate solution. They combine the reassuring home-like atmosphere with the safety of the hospital. In Belgium, the first alongside birth center " Le Cocon " (a low technicity unit distinct from the delivery room) offers now this type of alternative place of birth for women in Hôpital Erasme in Brussels.

Abstract
INTRODUCTION The last century focused all its attention on the care of the pathological pregnancies with remarkable results, at the price of fatal overmedicalisation in normal pregnancies. Efforts centered on the pregnant patients at low risk are being developped. OBJECTIVES To compare obstetric and neonatal outcomes obtained by independent midwives (IM) to a group control of pregnant women at low risk at Hospital Erasme. MATERIAL AND METHODS Retrospective constitution of a multivariated cohort case-witnesses 1:2 of patients at low risk including 128 followed in antenatal and delivered by the IM and 256 followed in antenatal and delivered by the group control Erasme (E) RESULTS: The rate of spontaneous vaginal delivery is significantly higher in the group IM (88,28 % versus 77,7 % in the group E). The rates of epidurals (66,79 % versus 37,50 %) and episiotomies (24,61 % versus 8,60 %) are significantly higher in the group E. Transfers to the neonatal unit are more frequent in the group E. CONCLUSION The obstetrics attitudes are less interventionist in the IM group. The reasons can be linked to bias selection or to different obstetrics practices in both groups. Positive effects in terms of maternal and neonatal outcomes are quite positive.

Abstract
UNLABELLED To assess the value of simulation based training in the management of obstetric emergencies. METHOD A search by keywords: obstetrics, gynecology, simulation, drills, emergency training restricted to randomized trials led to a selection of eight articles. RESULTS Shoulder dystocia simulation unmasked deficiencies in performing Mc Robert maneuver in nearly 20% of doctors in training as well as ineffective and potentially harmful maneuver such as pressure on the uterine fundus. Delivery of the impacted shoulder improved from 42.9% to 83.3% after simulation training leading to a shorter head to body delivery interval. In postpartum haemorrhage simulation, lack of knowledge on prostaglandins and alkaloids of ergot, delay to transfer the patient to the operating room (82% of cases) and a poor communication between different professionals were identified. Post simulation improvement was seen in knowledge, technical skills, team spirit and structured communication. In severe preeclampsia simulation, mistakes such as injection of undiluted magnesium sulphate, caesarean section on an unstable patient were identified and reduced by 75%. Management of magnesium sulphate toxicity was also improved after simulation training. CONCLUSION This review confirms the potential of simulation in training health professionals on management of obstetrics emergencies. Although the integration of this training modality into the curriculum of health care professionals in obstetrics and gynaecology seems beneficial, questions on the cost, the minimum standard of facilities, type of mannequins, human resources and frequency of drills required to achieve the learning objectives remain unanswered.

Abstract
To assess factors related with postpartum testing for diabetes and the mothers' knowledge about their infant's future risk for diabetes and obesity, we asked 87 women with gestational diabetes who delivered during a 28-month period, to perform a postpartum glucose screening. They were then asked to answer a telephone questionnaire regarding risk perception of diabetes and infant's risk, and were invited to undergo further glucose testing if they missed the first test. Postpartum screening was assessed according to medical, sociodemographic and interview characteristics. A total of 42.5% of women escaped initial postpartum screening and 43.0% escaped secondary testing. Performance of postpartum testing was related with sub-Saharan origin, BMI < 25 kg/m(2) and with high risk perception of developing permanent diabetes. Few women were informed about their infant's future risk.

Abstract
Pregnancy is associated with relative carbohydrate intolerance and insulin resistance. Gestational diabetes mellitus (GDM) is recognized as a risk factor for a number of adverse outcomes during pregnancy, including excessive fetal growth, increased incidence of birth trauma and neonatal metabolic abnormalities. This recognition has led to recommendations to screen all pregnant women for GDM and to treat those whose glucose tolerance tests exceed threshold criteria. Numerous epidemiological studies show that GDM affects between 1 and 25% of pregnancies, depending on the ethnicity of the population studied and the diagnostic criteria. Intervention to change lifestyle and, if maternal hyperglycemia persists, treatment with additional oral medication or insulin injections have shown to improve perinatal outcomes. Patients with GDM have a high risk of developing type 2 diabetes in the years after delivery and these women are encouraged to practice specific health behaviours (dietary habits, physical activity) during the postpartum period. The present article discusses the management of GDM in the light of data from the latest studies and international recommendations.

Abstract
For nearly 50 years, the strategy of screening and the diagnostic criteria for gestational diabetes have been the subject of endless controversies. They differ between countries and from one center to another, mainly because of the lack of hard data allowing to define glycemic thresholds at which a therapeutic management is needed. Recently, a large observational study has demonstrated the existence of a robust relationship between maternal blood sugar and several fetomaternal perinatal complications. This relationship is linear, with no clear threshold that would define gestational diabetes unambiguously. Meanwhile, two randomized intervention trials have shown that the therapeutic management of mild gestational diabetes was associated with improved perinatal outcomes. Based on these data, the "International Association of Diabetes and Pregnancy Study Group" (IADPSG) released new recommendations on screening methods and diagnostic criteria for gestational diabetes. Although already endorsed by several international associations and implemented in some countries, these recommendations still raise questions and criticisms. This is why the "Groupement des Gynécologues Obstétriciens de Langue Française de Belgique" (GGOLFB) organized a meeting between diabetologists and gynecologists which allowed to reach a consensus on the strategy that we intend to implement in our respective centers. The purpose of this paper is to briefly overview the recent advances in gestational diabetes and more particularly to make our key conclusions known to the medical community. This will enable the standardization of the management of gestational diabetes in the French-speaking part of Belgium.

Abstract
Small interfering RNA (siRNA) shows great promise in cancer therapy, but its effectiveness in vivo still remains a crucial issue for its transition into the clinics. Although the successful use of polyethylene glycol (PEG)ylated lipidic delivery systems have already been reported, most of the formulation procedures used are labour intensive and also result in unstable end products. We have previously developed a simple yet efficient hydration-of-freeze-dried-matrix (HFDM) method to entrap siRNA within lipid particles, in which the products exhibited superior stability. Here, we show that these HFDM-formulated particles are stable in the presence of serum and can deliver siRNA efficiently to tumours after intravenous administration. Using these particles, around 50% knockdown of the target gene expression was observed in tumours. With the use of siRNA targeting the E6/7 oncogenes expressed in cervical cancer, we showed a 50% reduction in tumour size. This level of tumour growth suppression was comparable to that achieved from cisplatin at the clinically used dose. Overall, our results demonstrate the feasibility of using HFDM-formulated particles to systematically administer E6/7-targeted siRNA for cervical cancer treatment. The simplicity of preparation procedure along with superior product stability obtained from our method offers an innovative approach for the in vivo delivery of siRNA.

Abstract
AIMS The objective of this study was to assess the relative bioavailability of oseltamivir carboxylate (active metabolite) following oral administration of the market suspension, the clinical trial suspension and the market capsule formulations of oseltamivir (prodrug) in healthy subjects. METHODS In this single-center, open-label, three-period crossover study, 24 healthy adult volunteers were randomized to receive one dose (150 mg oseltamivir) of each of the three formulations (market suspension, clinical trial suspension, market capsule formulation), with a 7-day washout period between each administration. Blood samples, collected for up to 48 h post-dosing, were analyzed for plasma oseltamivir and oseltamivir carboxylate. Adverse events were monitored. RESULTS Pharmacokinetic parameters for oseltamivir and oseltamivir carboxylate were similar for the three formulations. Bioequivalence for oseltamivir carboxylate was demonstrated between the market capsule and the two suspensions: 90% confidence intervals for the log-transformed Cmax, AUClast and AUCinf ratios fell within the 80 - 125% criteria. Similarly, the two suspensions were also demonstrated as bioequivalent for oseltamivir carboxylate. Oseltamivir was well tolerated. The majority of adverse events observed were mild in intensity, with the most common being nausea and headache. CONCLUSIONS This study demonstrates that the market suspension, the clinical trial suspension and the market capsule formulations of oseltamivir are bioequivalent for the active metabolite, oseltamivir carboxylate. Based on this finding, the market suspension may be used to achieve comparable exposure in patients unable to take capsules.

Abstract
Kidney transplantation can restore the fertility of women with chronic renal insufficiency, allowing them to bear children. Yet, pregnancy after renal graft is associated with high maternal and fetal morbidity. The purpose of this case-controlled retrospective study was to evaluate maternal and fetal outcomes of pregnancies in renal transplant recipients, and to compare the results to a control population. We studied 18 pregnancies in 14 renal grafted patients, between 1990 and 2003. Each pregnancy was paired for age, number of pregnancies and parity with 2 controls. The analyses concerned the presence of risk factors at the conception, the outcome of the pregnancy and the occurring of maternal-fetal complications. There were significantly more infections (50 % versus 11 %), anaemia (28 % versus 3 %), caesarean sections (72 % versus 14 %), intrauterin growth restriction (39 % versus 3 %), premature babies (44 % versus 8 %) and small weights at birth (50 % versus 8 %) in the transplanted women and a trend to an increased incidence of hypertensive complications. One baby of a transplanted mother died. No deterioration of renal function nor any maternal death occurred. In conclusion, the rates of maternal-fetal complications in pregnancies after kidney transplantation found in our hospital are similar to those of the literature and in comparison with controls, make them high-risk pregnancies. Nevertheless, by respecting certain criteria, the majority have a successful outcome.
