Toward machine-assisted tuning avoiding the underestimation of uncertainty in climate change projections.

Documenting the uncertainty of climate change projections is a fundamental objective of the inter-comparison exercises organized to feed into the Intergovernmental Panel on Climate Change (IPCC) reports. Usually, each modeling center contributes to these exercises with one or two configurations of its climate model, corresponding to a particular choice of "free parameter" values, resulting from a long and often tedious "model tuning" phase. How much uncertainty is omitted by this selection and how might readers of IPCC reports and users of climate projections be misled by its omission? We show here how recent machine learning approaches can transform the way climate model tuning is approached, opening the way to a simultaneous acceleration of model improvement and parametric uncertainty quantification.

Are general circulation models obsolete?

Traditional general circulation models, or GCMs-that is, three-dimensional dynamical models with unresolved terms represented in equations with tunable parameters-have been a mainstay of climate research for several decades, and some of the pioneering studies have recently been recognized by a Nobel prize in Physics. Yet, there is considerable debate around their continuing role in the future. Frequently mentioned as limitations of GCMs are the structural error and uncertainty across models with different representations of unresolved scales and the fact that the models are tuned to reproduce certain aspects of the observed Earth.

Increased risk of near term global warming due to a recent AMOC weakening.

Some of the new generation CMIP6 models are characterised by a strong temperature increase in response to increasing greenhouse gases concentration. At first glance, these models seem less consistent with the temperature warming observed over the last decades. Here, we investigate this issue through the prism of low-frequency internal variability by comparing with observations an ensemble of 32 historical simulations performed with the IPSL-CM6A-LR model, characterized by a rather large climate sensitivity.

Meckel-gruber syndrome: About an evocative case in French Guiana-When ultrasound is insufficient for accurate diagnosis in a complex syndrome.

In modern medicine, prenatal diagnosis can no longer be sufficient by ultrasound examination. The genetic technical progress and its contribution may remain a challenge in isolated sites with the consequences that this implies in perinatal health.

Predictors of abnormal cytology among HPV-infected women in remote territories of French Guiana.

Background: Cervical cancer prevention using cervical cytology is insufficiently sensitive, a significant proportion of HPV-infected women having normal cytology. The objective of the present study was to try to identify factors associated with abnormal cytology in HPV-infected women living in remote areas of French Guiana.

Methods: A study was conducted in women aged 20-65 years having HPV infections confirmed by HPV DNA detection using the GREINER-BIO-ONE kit.

The singular epidemiology of HPV infection among French Guianese women with normal cytology.

Background: In French Guiana, cervical cancer is the second most frequent cancer in females. The objective of the present study was to describe the prevalence of HPV infections in women with normal cervical cytology living in the remote villages of French Guiana.

Methods: Before the study, the study team communicated in the remote villages on the importance of screening.

[A Study of the relationship between craniofacial morphology and the occlusion in lacteal dentition: occipital remodeling specificities and basicranial individual features that play an occlusal key role].

Before performing any procedure or initiating early intervention on children in lacteal dentition, it is crucial to closely investigate a few key elements of the cranial base of the child. A first step of diagnostics is needed - the classification of the dysharmony ie its squelettal and/or functional element - before we prescribe a major orthopedic treatment or just stop dysfunctions using simple functional appliances. To confront these constraints of diagnostic, a set of 243 children in the lacteal dentition was examined.

Cervical cancer incidence in French Guiana: South American.

For the first time, the incidence of cervical cancer was estimated in French Guiana, an overseas French Territory of South America. A certified cancer registry collected exhaustive data on cervical cancer between 2003 and 2005. The age-standardized rate of invasive cervical cancer was 30.

Comparison of serum hepatitis C virus (HCV) RNA and core antigen levels in patients coinfected with human immunodeficiency virus and HCV and treated with interferon plus ribavirin.

Trak-C (Ortho-Clinical Diagnostics) is an enzyme-linked immunosorbent assay-based method capable of quantifying hepatitis C virus (HCV) core antigen (CA) in serum and could be an alternative to molecular detection and quantification of HCV RNA. We have evaluated the Trak-C assay in comparison with an HCV RNA quantitative assay (Versant HCV v3.0; Bayer Diagnostics) in the follow-up of 348 treated, human immunodeficiency virus (HIV)/HCV-coinfected patients included in the ANRS HC02 RIBAVIC trial.

A virologic survey of patients admitted to a critical care unit for acute cardiorespiratory failure.

Objective: To document the prevalence of respiratory virus infections in patients with chronic cardiac or pulmonary disorders admitted to a critical care unit for acute cardiorespiratory failure.

Design, Setting, Patients: The study took place in a critical care unit during two consecutive winters. All patients admitted to the unit for acute respiratory or cardiac failure were enrolled.

Liver transplant combined with heart transplant in severe heterozygous hypercholesterolemia: report of the first case and review of the literature.

Familial hypercholesterolemia (FH) is a dominant inherited disease of low-density lipoprotein (LDL) metabolism caused by mutations of LDL receptors mainly located in the liver. This metabolic disorder is responsible for severe cardiovascular disease, from coronary lesions to chronic heart failure (CHF). Liver transplantation in homozygous FH provides the missing functional LDL receptors and thus partially restores LDL receptor activity to more than 50% of normal.

[Internet use for telemedecine: fetal medicine applications].

Purpose: Assessment of the transmission of still and moving images via the Internet for teleconsultations in fetal medicine.

Material: and methods: Implementation fo two PC systems linked via the internet for the transmission of fixed ultrasound, radiography and scanner images, as well as moving ultrasound images. The assessment took into account was based upon the compression factor.

Bile and blood ratios of cyclosporin and its metabolites in patients on continuous infusion during the first three weeks after liver transplantation.

Ten patients with orthotopic liver transplants were investigated during routine therapeutic monitoring to study the relationship between the concentrations of cyclosporin and its metabolites in blood, bile and urine, and whether this information can provide early signs of severe hepatic disorders post-transplantation. Cyclosporin (Sandimmun®) was administered by continuous infusion at a constant rate of 5 mg/kg/day, modified to keep the blood cyclosporin concentration within the target range (400 to 500 μg/L). The concentrations of cyclosporin and combined cyclosporin-metabolites in blood, bile and urine were assayed daily during the 3 post-transplantation weeks that the patients spent in intensive care.

[Mesentric venous thrombosis. Risk factors, treatment and outcome. An analysis of 18 cases].

Eighteen patients with an acute thrombosis of the splanchnic veins were reviewed. Most of apparently idiopathic cases of splanchnic vein thrombosis are related to an increased coagulation related to a congenital or acquired defect of haemostasis. The aim of this study was to assess the effects of a new and effective treatment.

[Antibiotic prophylaxis in surgery of the esophagus].

Surgery of oesophagus carcinoma is a long and major procedure. Perioperative radiochemotherapy is often required. Therefore many factors favour the occurrence of local and general postoperative infection, justifying an antibiotic prophylaxis directed against oesophageal and gastric flora.

[Calibrated latero-lateral portacaval anastomosis in the treatment of digestive hemorrhages by portal hypertension in the cirrhotic patient].

The calibrated side to side portocaval shunt was described in 1979 by P. Marion. This type of shunt preserves a hepatopedal blood flow by maintaining portocaval pressure gradient superior to halve of the initial gradient.

Intrapleural bupivacaine analgesia after thoraco-abdominal incision for oesophagectomy.

Intrapleural bupivacaine administration is said to produce good analgesia for the pain induced by a subcostal incision. However, reports of its efficacy after thoracotomy are conflicting. The goal of this study was to compare the analgesia produced by intrapleural administration of bupivacaine after oesophagectomy using a thoraco-abdominal incision with that obtained from intrapleural saline.

[Hereditary deficiency of antithrombin III, protein C and protein S. A study of 31 patients from 8 unrelated families].

The families of eight unrelated patients were studied with regard to a hereditary deficiency in antithrombin III (ATIII), protein C, or protein S. These deficiencies were recognized in the course of investigations for deep-vein thrombosis (DVT) in the eight patients. A group of 31 individuals (patients and family members), mostly less than 40-year-old was explored.

[Biological criteria for the evaluation of prophylactic treatment with a low molecular weight heparin (Kabi 2165)].

Efficacy of a low molecular weight heparin (Kabi 2165) was compared with that of non-fractionated heparin in the prevention of abdominal surgery postoperative venous thrombosis by means of a double-blind randomized trial in 79 patients. Determination of D. dimers in these patients allowed assessment of specificity of this assay for detection of postoperative venous thrombosis.

Ultrasound of normal skin.

The authors have used a commercially available real-time sector scanner and a 10-MHz probe with a built-in water path for B-mode imaging of the normal skin. Measurements have been performed in 10 volunteers at 18 sites on the body surface. Normal skin thickness ranges from 1.

[Evaluation of the activity and quality of care in a digestive surgery department].

Since 1980, details of all patients operated upon in a digestive surgery unit have been entered on record-cards with the view of obtaining information on the activity of the unit and improving post-operative care. Over a 3-year period, 2005 patients underwent surgery, 25% of them for cancerous lesions. Biliary tract operations (385 patients), fundoplication by the abdominal route for gastro-oesophageal reflux (58 patients) and curative resection of the colon for carcinoma (100 patients) were set apart for evaluation.
