TRIDENT-2: National Implementation of Genome-wide Non-invasive Prenatal Testing as a First-Tier Screening Test in the Netherlands.

The Netherlands launched a nationwide implementation study on non-invasive prenatal testing (NIPT) as a first-tier test offered to all pregnant women. This started on April 1, 2017 as the TRIDENT-2 study, licensed by the Dutch Ministry of Health. In the first year, NIPT was performed in 73,239 pregnancies (42% of all pregnancies), 7,239 (4%) chose first-trimester combined testing, and 54% did not participate. The number of trisomies 21 (239, 0.33%), 18 (49, 0.07%), and 13 (55, 0.08%) found in this study is comparable to earlier studies, but the Positive Predictive Values (PPV)-96% for trisomy 21, 98% for trisomy 18, and 53% for trisomy 13-were higher than expected. Findings other than trisomy 21, 18, or 13 were reported on request of the pregnant women; 78% of women chose to have these reported. The number of additional findings was 207 (0.36%); these included other trisomies (101, 0.18%, PPV 6%, many of the remaining 94% of cases are likely confined placental mosaics and possibly clinically significant), structural chromosomal aberrations (95, 0.16%, PPV 32%,) and complex abnormal profiles indicative of maternal malignancies (11, 0.02%, PPV 64%). The implementation of genome-wide NIPT is under debate because the benefits of detecting other fetal chromosomal aberrations must be balanced against the risks of discordant positives, parental anxiety, and a potential increase in (invasive) diagnostic procedures. Our first-year data, including clinical data and laboratory follow-up data, will fuel this debate. Furthermore, we describe how NIPT can successfully be embedded into a national screening program with a single chain for prenatal care including counseling, testing, and follow-up.

Arrhythmogenicity of scuba diving: Holter monitoring in a hyperbaric environment.

INTRODUCTION: About 26% of diving-related fatalities are caused by cardiac disease, part of which might be associated with fatal arrhythmias. This raises the question as to whether fatal arrhythmias are being provoked by hyperbaric conditions themselves or if exercise or stress provokes the fatal arrhythmias in cases of underlying (ischemic) cardiac disease. OBJECTIVE: To measure the influence of hyperbaric conditions (50 msw) on cardiac conduction and arrhythmias in professional divers by means of ECG. METHODS: This is a prospective study on military divers in a hyperbaric chamber with continuous ECG monitoring using Holter registrations. Supraventricular and ventricular ectopy was registered during hyperbaric conditions. RR, PR, QRS, QT and QTc intervals were calculated at 50 msw and compared with ECGs at rest. RESULTS: Included were 17 male military divers who made 20 dives. A total of 10 PVCs, 45 PACs, four atrial runs and four atrial pairs were seen. Significant prolongation of the PR interval was seen and a decrease of in QRS duration at 50 msw. There was no significant change in the RR, QT and QTc intervals. CONCLUSION: In these divers, no clinically relevant arrhythmias were observed during wet dives in a recompression chamber at 50 msw. We observed a small prolongation of PR interval that is probably not clinically relevant in divers without any known conduction disorders.

Soluble TLR2 and 4 concentrations in cerebrospinal fluid in HIV/SIV-related neuropathological conditions.

HIV in the central nervous system (CNS) mainly infects microglial cells which are known to express toll-like receptors (TLRs). This paper aimed to study the role of soluble TLR2 (sTLR2), sTLR4, and other inflammatory markers in cerebrospinal fluid (CSF) in HIV/Simian immunodeficiency virus (SIV)-related neurological sequelae. We determined sTLR2 and sTLR4 levels in CSF and serum/plasma of SIV-infected rhesus macaques with and without neurological sequelae, as well as in HIV-infected patients with and without cognitive impairments and Alzheimer's disease (AD) patients and matched controls. CSF cytokines and chemokines levels were analyzed in macaques as markers of neuroinflammation, while neopterin and S100B CSF concentrations were measured in HIV-infected patients as microglial and astrocyte marker, respectively. We found detectable levels of sTLR2 and sTLR4 in CSF of macaques and humans. Furthermore, CSF sTLR2 and sTLR4 concentrations were higher in SIV-infected macaques with neurological sequelae compared to those without neurological complications (p = 0.0003 and p = 0.0006, respectively). CSF IL-8 and monocyte chemoattractant protein-1 (MCP-1) levels were elevated in macaques with neurological sequelae, and a positive correlation was found between CSF levels of sTLR2/4 and IL-8 and MCP-1. Also in humans, elevated CSF sTLR4 levels were found in HIV-infected patients with cognitive impairments compared to HIV-infected patients with normal cognition (p = 0.019). Unlike CSF S100B levels, neopterin correlated positively with sTLR2 and sTLR4. No difference was found in plasma and CSF sTLR2 and sTLR4 levels between AD patients and control subjects (p = 0.26). In conclusion, CSF sTLR2 and sTLR4 may play a role in HIV/SIV-related neuroinflammation and subsequent neuropathology.

Influence of cut-off value on prevalence of short cervical length.

OBJECTIVE: To assess the distribution of cervical length (CL) in a large cohort of asymptomatic low-risk women with singleton pregnancy and no previous preterm birth and to explain the low prevalence of short CL ≤ 30 mm in this cohort. METHODS: This was a secondary analysis of a multicenter cohort study with an embedded randomized controlled trial (Triple P trial; NTR-2078) on the prevention of preterm birth with progesterone. In the cohort study, CL was measured in asymptomatic low-risk women with singleton pregnancy to investigate its predictive capacity to identify those at increased risk for preterm birth. A short CL was defined by a cut-off value of ≤ 30 mm, based on existing literature. Women with a short CL were subsequently included in a randomized controlled trial evaluating the effect of progesterone, compared with placebo, on preterm birth. In total, 57 centers and 20 234 women participated in the study. Normal distributions for CL were simulated based on the mean and SD of the original data. The distribution of CL was assessed for each individual center and measurements were compared between levels of care: primary (29 ultrasound centers), secondary (21 general hospitals) and tertiary (seven university medical centers) care institutions. Comparison was also performed between centers with low, intermediate and high volume of CL measurements. CL distributions before (n = 12 284 women) and after (n = 7950 women) a national symposium, at which the prevalence of short CL measurements was addressed publicly, were analyzed. RESULTS: Between November 2009 and August 2013, 20 234 women had CL measurements, of whom 367 (1.8%) had a short CL. Mean ± SD CL was 44.2 ± 7.8 mm. A 'dip' in the distribution of CL measurements between 20 and 30 mm was observed, defined by a ratio of < 50% when comparing the number of measurements in observed and simulated normal distributions. The dip was present in 89% of participating centers. All centers showed a dip in the distribution of measurements ≤ 30 mm when analyzed according to the level of care and volume of measurements. A significant difference was found when comparing the distribution before and after publicly addressing the low prevalence of short CL (1.7% vs 2.0% of measurements were ≤ 30 mm, respectively; P < 0.001). CONCLUSIONS: A cut-off value of 30 mm for CL was used to include women in a randomized clinical trial that was embedded in a cohort study. We suggest that the use of a predefined cut-off value for a short cervix influences the distribution of the CL measurements. Since the measurement is not blinded, preference of assessors for the control or intervention arms may have introduced selection bias. This might have resulted in fewer measurements around the cut-off value. Other trials using similar designs could benefit from this observation and take precautions to avoid selection bias.

Midpregnancy Cervical Length in Nulliparous Women and its Association with Postterm Delivery and Intrapartum Cesarean Delivery.

OBJECTIVE: To evaluate the association between midpregnancy cervical length and postterm delivery and cesarean delivery during labor. STUDY DESIGN: In a multicenter cohort study, cervical length was measured in low-risk singleton pregnancies between 16 and 22 weeks of gestation. From this cohort, we identified nulliparous women who delivered beyond 34 weeks and calculated cervical length quartiles. We performed logistic regression to compare the risk of postterm delivery and intrapartum cesarean delivery to cervical length quartiles, using the lowest quartile as a reference. We adjusted for induction of labor, maternal age, ethnicity, cephalic position, preexisting hypertension, and gestational age at delivery. RESULTS: We studied 5,321 nulliparous women. Women with cervical length in the 3rd and 4th quartile were more likely to deliver at 42(+0) to 42(+6) weeks (adjusted odds ratio [aOR] 2.02, 95% confidence interval [CI] 1.07-3.79 and aOR 1.97, 95% CI 1.06-3.67, respectively). The frequency of intrapartum cesarean delivery increased with cervical length quartile from 9.4% in the 1st to 14.9% in the 4th quartile (p = 0.01). This increase was only present in intrapartum cesarean delivery because of failure to progress and not because of fetal distress. CONCLUSION: The longer the cervix at midtrimester the higher the risk of both postterm delivery and intrapartum cesarean delivery.

Effect of e-learning on quality of cervical-length measurements.

OBJECTIVES: To assess the effect of implementation of a newly developed e-learning module on the quality of cervical-length measurements. METHODS: With the introduction of cervical-length (CL) measurement in a research setting, a CL measurement e-learning module (CLEM) was developed with the purpose to enhance the knowledge and skills of experienced ultrasonographers. CLEM was designed specifically for ultrasonographers who perform ultrasound in a general obstetrical practice but who do not regularly perform CL measurements. CLEM consists of five theoretical questions and three caliper-placement tests to learn the CL measurement technique. The quality of the CL measurements of CLEM participants was compared with images of non-participants using a CL measurement image score (CIS), defined as the sum of six items which assess the quality of the image. Each CLEM participant submitted five CL images and the images of non-CLEM participants were selected randomly from an ultrasound database. RESULTS: The CIS of the CLEM participants (n = 61) were significantly higher than those of non-CLEM participants (n = 23) (164.9 vs 155.6, respectively; P = 0.03). Visualization of the internal os and positioning of the calipers on the internal and external ora were found to have significantly higher CIS among the CLEM participants than among the non-CLEM participants (P = 0.001 and P < 0.001, respectively). CONCLUSIONS: Introducing CLEM may improve the quality of CL measurements obtained by trained and untrained sonographers.

Preventing Preterm Birth with Progesterone in Women with a Short Cervical Length from a Low-Risk Population: A Multicenter Double-Blind Placebo-Controlled Randomized Trial.

OBJECTIVE: The objective of this study was to evaluate the effectiveness of vaginal progesterone in reducing adverse neonatal outcome due to preterm birth (PTB) in low-risk pregnant women with a short cervical length (CL). STUDY DESIGN: Women with a singleton pregnancy without a history of PTB underwent CL measurement at 18 to 22 weeks. Women with a CL ≤ 30 mm received vaginal progesterone or placebo. Primary outcome was adverse neonatal outcome, defined as a composite of respiratory distress syndrome, bronchopulmonary dysplasia, intracerebral hemorrhage > grade II, necrotizing enterocolitis > stage 1, proven sepsis, or death before discharge. Secondary outcomes included time to delivery, PTB before 32, 34, and 37 weeks of gestation. Analysis was by intention to treat. RESULTS: Between 2009 and 2013, 20,234 women were screened. A CL of 30 mm or less was seen in 375 women (1.8%). In 151 women, a CL ≤ 30 mm was confirmed with a second measurement and 80 of these women agreed to participate in the trial. We randomly allocated 41 women to progesterone and 39 to placebo. Adverse neonatal outcomes occurred in two (5.0%) women in the progesterone and in four (11%) women in the control group (relative risk [RR], 0.47; 95% confidence interval [CI], 0.09-2.4). The use of progesterone resulted in a nonsignificant reduction of PTB < 32 weeks (2.0 vs. 8.0%; RR, 0.33; 95% CI, 0.04-3.0) and < 34 weeks (7.0 vs. 10%; RR, 0.73; 95% CI, 0.18-3.1) but not on PTB < 37 weeks (15 vs. 13%; RR, 1.2; 95% CI, 0.39-3.5). CONCLUSION: In women with a short cervix, who are otherwise low risk, we could not show a significant benefit of progesterone in reducing adverse neonatal outcome and PTB.

Multicentre randomized controlled trial comparing ferric(III)carboxymaltose infusion with oral iron supplementation in the treatment of preoperative anaemia in colorectal cancer patients.

BACKGROUND: At least a third of patients with a colorectal carcinoma who are candidate for surgery, are anaemic preoperatively. Preoperative anaemia is associated with increased morbidity and mortality. In general practice, little attention is paid to these anaemic patients. Some will have oral iron prescribed others not. The waiting period prior to elective colorectal surgery could be used to optimize a patients' physiological status. The aim of this study is to determine the efficacy of preoperative intravenous iron supplementation in comparison with the standard preoperative oral supplementation in anaemic patients with colorectal cancer. METHODS/DESIGN: In this multicentre randomized controlled trial, patients with an M0-staged colorectal carcinoma who are scheduled for curative resection and with a proven iron deficiency anaemia are eligible for inclusion. Main exclusion criteria are palliative surgery, metastatic disease, neoadjuvant chemoradiotherapy (5 × 5 Gy = no exclusion) and the use of Recombinant Human Erythropoietin within three months before inclusion or a blood transfusion within a month before inclusion. Primary endpoint is the percentage of patients that achieve normalisation of the haemoglobin level between the start of the treatment and the day of admission for surgery. This study is a superiority trial, hypothesizing a greater proportion of patients achieving the primary endpoint in favour of iron infusion compared to oral supplementation. A total of 198 patients will be randomized to either ferric(III)carboxymaltose infusion in the intervention arm or ferrofumarate in the control arm. This study will be performed in ten centres nationwide and one centre in Ireland. DISCUSSION: This is the first randomized controlled trial to determine the efficacy of preoperative iron supplementation in exclusively anaemic patients with a colorectal carcinoma. Our trial hypotheses a more profound haemoglobin increase with intravenous iron which may contribute to a superior optimisation of the patient's condition and possibly a decrease in postoperative morbidity.

Vitamin D status is not associated with inflammatory cytokine levels during experimental human endotoxaemia.

Vitamin D has been shown to modulate innate immune responses in vitro and ex vivo; however, human in-vivo data are lacking. At high latitudes, seasonal vitamin D deficiency is common due to alternating ultraviolet (UV)-B radiation exposure. In the present study, we investigated whether levels of 25 hydroxyvitamin D(3) [25(OH)D(3) ] and its active metabolite 1,25 dihydroxyvitamin D(3) [1,25(OH)(2) D(3) ] are subject to seasonal variation and whether plasma levels of these vitamin D metabolites correlate with the in-vivo cytokine response during experimental human endotoxaemia [administration of lipopolysaccharide (LPS) in healthy volunteers]. Plasma levels of 25(OH)D(3) and 1,25(OH)(2) D(3) were determined in samples obtained just prior to administration of an intravenous bolus of 2 ng/kg LPS (derived from Escherichia coli O:113) in 112 healthy male volunteers. In the same subjects, plasma levels of the inflammatory cytokines tumour necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 were analysed serially after endotoxin administration. Plasma levels of 1,25(OH)(2) D(3) , but not 25(OH)D(3) , were subject to significant seasonal variation, with lower levels in autumn and winter. 25(OH)D(3) and 1,25(OH)(2) D(3) levels did not correlate with plasma cytokine responses. Furthermore, 25(OH)D(3) deficient subjects (< 50 nmol/l) displayed an identical cytokine response compared with sufficient subjects. In conclusion, plasma levels of vitamin D are not correlated with the LPS-induced TNF, IL-6 and IL-10 cytokine response in humans in vivo. These findings question the direct role of vitamin D in modulation of the innate immune response.

Pharmacokinetics of the combination raltegravir/atazanavir in HIV-1-infected patients.

OBJECTIVES: To evaluate the use of raltegravir with unboosted atazanavir in combination with one nucleoside reverse transcriptase inhibitor (NRTI) (lamivudine or emtricitabine) as a potentially well-tolerated once-daily (qd) maintenance regimen. METHODS: We compared the pharmacokinetics of raltegravir 400 mg twice daily (bid) with raltegravir 800 mg qd in HIV-infected patients (n=17) on unboosted atazanavir (600 mg qd) in combination with lamivudine or emtricitabine. RESULTS: The area under the plasma concentration vs. time curve for a dose interval t (AUC0 -t ) of 800 mg qd divided by 2 was not significantly different from the AUC0 -t of 400 mg bid (P=0.664) but the minimum concentration (C min ) was 72% lower with the qd regimen (P=0.002). The regimen was well tolerated and the viral load remained undetectable in all patients during the 6 weeks of the study follow-up. CONCLUSIONS: A qd regimen of raltegravir 800 mg, atazanavir 600 mg and lamivudine or emtricitabine resulted in favourable pharmacokinetic profiles and good short-term safety and efficacy data. Larger phase IIb studies are needed to explore this novel regimen.

Dynamics of nasopharyngeal bacterial colonisation in HIV-exposed young infants in Tanzania.

OBJECTIVES: To estimate the prevalence of nasopharyngeal bacterial colonisation (NPBC) patterns in young Tanzanian HIV-exposed infants and to analyse the influence of maternal NPBC and of the infant's HIV status on the NPBC pattern. METHODS: Longitudinal cohort study of neonates born to HIV-infected mothers visiting Kilimanjaro Christian Medical Centre, Tanzania, between 2005 and 2009. Demographic and clinical data and nasopharyngeal bacterial cultures were obtained at the age of 6 weeks, 3 and 6 months, and at one time point, a paired mother-infant nasopharyngeal swab was taken. RESULTS: Four hundred and twenty-two swabs were taken from 338 eligible infants. At 6 weeks of age, colonisation rates were 66% for Staphylococcus aureus, 56% for Streptococcus pneumoniae, 50% for Moraxella catarrhalis and 14% for Haemophilus influenzae. Colonisation with S. aureus diminished over time and was more common in HIV-infected infants. S. pneumoniae and H. influenzae colonisation rose over time and was more prevalent in HIV-uninfected children. Co-colonisation of S. pneumoniae with H. influenzae or M. catarrhalis was mostly noticed in HIV-infected infants. S. pneumoniae and M.catarrhalis colonisation of the mother was a risk factor for colonisation in HIV-uninfected infants, while maternal S. aureus colonisation was a risk factor for colonisation in HIV-infected infants. Among the 104 S. pneumoniae isolates, 19F was most prevalent, and 57 (55%) displayed capsular serotypes represented in the 13-valent pneumococcal conjugate vaccine. CONCLUSIONS: NPBC was common in Tanzanian HIV-exposed infants. The significant prevalence of pneumococcal vaccine serotypes colonising this paediatric population justifies the use of the 13-valent pneumococcal vaccine to reduce the burden of pneumococcal invasive disease.

Ziprasidone--not haloperidol--induces more de-novo neurogenesis of adult neural stem cells derived from murine hippocampus.

INTRODUCTION: Here, we present a stem-cell based study on the de-novo generation of beta-III-tubulin-positive neurons after treatment with the classic antipsychotic drug haloperidol or after treatment with the second-generation antipsychotic (SGA) ziprasidone. METHODS: Adult neural stem cells (ANSC) dissociated from the adult mouse hippocampus were expanded in cell culture with basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF). ANSC differentiated upon withdrawal of EGF and bFGF. RESULTS AND DISCUSSION: Ziprasidone generated significantly more beta-III-tubulin-positive neurons than haloperidol during the differentiation of adult neural stem cells isolated from murine hippocampus (ANSC). We assume that this net increase in neurogenesis by ziprasidone relies on this drug's 5-HT1A receptor affinity, which is not present in the haloperidol molecule, since the inactivation by WAY100621 impeded this process. These data could possibly suggest a clinical relevance for studying antipsychotic drugs in the stem cell paradigm employed in this study.

Routinization of prenatal screening with the non-invasive prenatal test: pregnant women's perspectives.

Due to the favorable test characteristics of the non-invasive prenatal test (NIPT) in the screening of fetal aneuploidy, there has been a strong and growing demand for implementation. In the Netherlands, NIPT is offered within a governmentally supported screening program as a first-tier screening test for all pregnant women (TRIDENT-2 study). However, concerns have been raised that the test's favorable characteristics might lead to uncritical use, also referred to as routinization. This study addresses women's perspectives on prenatal screening with NIPT by evaluating three aspects related to routinization: informed choice, freedom to choose and (personal and societal) perspectives on Down syndrome. Nationwide, a questionnaire was completed by 751 pregnant women after receiving counseling for prenatal screening. Of the respondents, the majority (75.5%) made an informed choice for prenatal screening as measured by the multidimensional measure of informed choice (MMIC). Education level and religious affiliation were significant predictors of informed choice. The main reason to accept screening was "seeking reassurance" (25.5%), and the main reason to decline was "every child is welcome" (30.6%). The majority of respondents (87.7%) did not perceive societal pressure to test. Differences between test-acceptors and test-decliners in personal and societal perspectives on Down syndrome were found. Our study revealed high rates of informed decision-making and perceived freedom to choose regarding fetal aneuploidy screening, suggesting that there is little reason for concern about routinization of NIPT based on the perspectives of Dutch pregnant women. Our findings highlight the importance of responsible implementation of NIPT within a national screening program.

Regulation of cytokine responses by seasonality of vitamin D status in healthy individuals.

The immune modulating capacity of vitamin D(3) is well-recognized. Ultra-violet (UV) exposure determines production of vitamin D(3) in vivo and varies through the course of the year, especially in temperate regions. However, it is not known whether the human innate immune response differs due to seasonality. To validate the seasonal effects of vitamin D(3) , the effect of 1,25(OH)(2) D(3) on peripheral blood mononuclear cells (PBMC) cytokine response was first determined in vitro. 1,25(OH)(2) D(3) decreased interleukin (IL)-6 and tumour necrosis factor (TNF)-α release by PBMC stimulated with tripalmitoyl-S-glycerylcysteine (Pam3Cys) or lipopolysaccharide (LPS). Subsequently, ex-vivo stimulation studies were performed in 15 healthy volunteers through the course of the four seasons of the year. PBMC were isolated and stimulated with Toll-like receptor (TLR)-2 and TLR-4 ligands Pam3Cys and LPS, respectively. Circulating concentrations of 25(OH)D(3) and 1,25(OH)(2) D(3) were higher during summer (P<0·05) and a down-regulation of TLR-4-mediated IL-1ß, IL-6, TNF-α, interferon (IFN)-γ and IL-10 production in summer was observed compared to winter (P<0·05). The variation in cytokine response upon TLR-2 (Pam3Cys) stimulation was moderate throughout the four seasons. The repressed cytokine production during the summer months could be explained partly by the reduced cell-membrane expression of TLRs. Physiological variation in vitamin D(3) status through the four seasons of the year can lead to alteration in the innate immune responses. Elevated vitamin D(3) level in vivo is associated with down-regulation of cytokine response through diminished surface expression of pattern recognition receptors.

Aetiology of acute febrile illness in children in a high malaria transmission area in West Africa.

OBJECTIVES: Areas with declining malaria transmission in sub-Saharan Africa have recently witnessed important changes in the aetiology of childhood acute febrile illness (AFI). We describe the aetiology of AFI in a high malaria transmission area in rural Burkina Faso. METHODS: In a prospective hospital-based diagnostic study, children aged 3 months to 15 years with AFI were recruited and assessed using a systematic diagnostic protocol, including blood cultures, whole blood PCR on a selection of bacterial pathogens, malaria diagnostics and a multiplex PCR on nasopharyngeal swabs targeting 21 viral and 4 bacterial respiratory pathogens. RESULTS: A total of 589 children with AFI were enrolled from whom an infectious disease was considered in 575 cases. Acute respiratory tract infections, malaria and invasive bacterial infections (IBI) accounted for 179 (31.1%), 175 (30.4%) and 75 (13%) of AFI cases respectively; 16 (21.3%) of IBI cases also had malarial parasitaemia. A viral pathogen was demonstrated from the nasopharynx in 157 children (90.7%) with respiratory tract symptoms. Of all children with viral respiratory tract infections, 154 (92.4% received antibiotics, whereas no antibiotic was provided in 13 (17%) of IBI cases. CONCLUSIONS: Viral respiratory infections are a common cause of childhood AFI in high malaria transmission areas, next to malaria and IBI. These findings highlight the importance of interventions to improve targeted treatment with antimicrobials. Most patients with viral infections received antibiotics unnecessarily, while a considerable number with IBI did not receive antibiotics.

Is asymptomatic bacteriuria associated with short cervical length in women with a singleton pregnancy, a secondary analysis of two national cohort studies with small embedded randomized controlled trials.

OBJECTIVE: To assess the association between asymptomatic bacteriuria (ASB) and short cervical length (CL), since they are both associated with preterm delivery. STUDY DESIGN: In two prospective multicentre cohort studies, pregnant women were screened for the presence of ASB and short CL (≤25 mm). We compared CL in women with and without ASB. Both studies had a small randomised clinical trial embedded. RESULTS: Our study population comprised 1 610 women, of whom 114 were ASB positive. Median cervical length was similar in women with and without ASB (44.0 vs 44.0 mm, P = 0.60). More women in the ASB positive group had a short CL compared to the ASB negative group (1.8 % versus 0.4 %, P = 0.047)). The gestational age at delivery did not differ between the groups (ranging from 38 + 3 in women with ASB and short CL to 39 + 5 in women without ASB with a short CL P = 0.52). No preterm births occurred in women with a short cervical length (regardless of ASB status). In the women without ASB and no short CL 4.8 % had a preterm birth, in the women with ASB but not a short CL 4.1 % had a preterm birth. CONCLUSION: While ASB status did not influence median cervical length, we found a significant relationship between a short CL and ASB positive women. We found no statistical significant difference on the preterm birth rate and mean gestational age.

Perinatal exposure of rats to the HIV drug efavirenz affects medial prefrontal cortex cytoarchitecture.

Efavirenz (EFV) is used for antiretroviral treatment of HIV infection, and successfully inhibits viral replication and mother-to-child transmission of HIV during pregnancy and childbirth. Unfortunately, the drug induces neuropsychiatric symptoms such as anxiety and depressed mood and potentially affects cognitive performance. EFV acts on, among others, the serotonin transporter and serotonin receptors that are expressed in the developing brain. Yet, how perinatal EFV exposure affects brain cytoarchitecture remains unclear. Here, we exposed pregnant and lactating rats to EFV, and examined in the medial prefrontal cortex (mPFC) of their adult offspring the effects of the maternal EFV exposure on cortical architecture. We observed a significant decrease in the number of cells, mainly mature neurons, in the infra/prelimbic and cingulate cortices of adult offspring. Next, we found an altered cortical cytoarchitecture characterized by a significant reduction in deep- and superficial-layer cells. This was accompanied by a sharp increase in programmed cell death, as we identified a significantly higher number of cleaved Caspase-3-positive cells. Finally, the serotonergic and dopaminergic innervation of the mPFC subdomains was increased. Thus, the perinatal exposure to EFV provoked in the mPFC of adult offspring cell death, significant changes in cytoarchitecture, and disturbances in serotonergic and dopaminergic innervation. Our results are important in the light of EFV treatment of HIV-positive pregnant women, and its effect on brain development and cognitive behavior.

Skin disorders in HIV-infected patients from West Java.

AIM: to describe the spectrum of HIV-related skin disorders as well as their prevalence and relation to CD4-cell counts among HIV-seropositive patients from West Java, Indonesia. METHODS: all HIV-positive patients presenting in 2008 at the HIV-clinic, Hasan Sadikin Hospital, were included in a cross-sectional study. Patients who had a skin complaint were examined by a dermatologist. Skin diseases were classified based on ICD 10. RESULTS: among 843 patients, 121 (14.4%) had a skin complaint, consisting of skin manifestations (73.3%), drug eruptions (30.5%), and sexually transmitted infections (15.7%), some of them had more than one diseases. The most common skin manifestations were drug eruptions, pruritic papular eruptions, seborrhoeic dermatitis, herpes zoster, dermatophytosis, and bacterial skin infections. Among patients who started nevirapine, 6.4% (95%CI: 3.9% - 8.9%) developed any kind of drug eruption, and 1.4% (95%CI 0.2%-2.6%) developed a severe drug eruption. No cases of Kaposi sarcoma, penicilliosis, eosinophilic folliculitis were seen, however one case of histoplasmosis was diagnosed. CONCLUSION: this is the first report describing the prevalence and characteristic of skin manifestation in HIV-positive in Indonesia. Indonesian physicians should be alert about HIV when patient presents with certain skin manifestations. The rate of severe drug eruptions following treatment with nevirapine is a cause of concern that needs further study.

Prevention and treatment of HIV addicted patients: a biopsychosocial approach.

Injecting drug use is the main route of HIV transmission in many parts of Indonesia. Efforts to prevent HIV-transmission through injecting drug use mostly focus on subjects who actively inject. In scientific publications, the term 'injecting drug users' tends to be used without a clear definition and without specifying the pattern of drug use as current or former drug use, frequency, duration, type of injected drug(s) or context (e.g. imprisonment). Actually, injecting drug users (IDUs) have different drug use patterns, risk behavior, somatic co-morbidity, psychiatric co-morbidity, and psychosocial problems. In fact, these patients are suffering from addiction as a chronic brain disease in co-occurrence with somatic and psychiatric disorder and many social problems. Failing in addressing the problems comprehensively will lead to the failure of drug treatment. This is why addiction can be best studied and treated from a biopsychosocial perspective. Accordingly, treatment goals can be differentiated in crisis intervention, cure or recovery (detoxification, relapse prevention), and care or partial remission (stabilization and harm reduction). In summary, injecting drug use in Indonesia is not a single entity and patient oriented prevention and care for IDUs, especially focusing on their addiction, should be addressed to prevent the transmission of HIV/AIDS.
