Abstract
Hermand, Eric, Léo Lesaint, Laura Denis, Jean-Paul Richalet, and François J. Lhuissier. A step test to evaluate the susceptibility to severe high-altitude illness in field conditions. High Alt Med Biol. 00:000-000, 2024.-A laboratory-based hypoxic exercise test, performed on a cycle ergometer, can be used to predict susceptibility to severe high-altitude illness (SHAI) through the calculation of a clinicophysiological SHAI score. Our objective was to design a field-condition test and compare its derived SHAI score and various physiological parameters, such as peripheral oxygen saturation (SpO2), and cardiac and ventilatory responses to hypoxia during exercise (HCRe and HVRe, respectively), to the laboratory test. A group of 43 healthy subjects (15 females and 28 males), with no prior experience at high altitude, performed a hypoxic cycle ergometer test (simulated altitude of 4,800 m) and step tests (20 cm high step) at 3,000, 4,000, and 4,800 m simulated altitudes. According to tested altitudes, differences were observed in O2 desaturation, heart rate, and minute ventilation (p < 0.001), whereas the computed HCRe and HVRe were not different (p = 0.075 and p = 0.203, respectively). From the linear relationships between the step test and SHAI scores, we defined a risk zone, allowing us to evaluate the risk of developing SHAI and take adequate preventive measures in field conditions, from the calculated step test score for the given altitude. The predictive value of this new field test remains to be validated in real high-altitude conditions.

Abstract
BACKGROUND ASN002 is an oral dual inhibitor of Janus kinase and spleen tyrosine kinase, which are involved in the pathogenesis of atopic dermatitis (AD) through their regulatory role on T helper (Th)1, Th2 and Th17/Th22 pathways. OBJECTIVES The objectives of this study were to evaluate the efficacy, safety, pharmacokinetics and effects on systemic biomarkers of ASN002 in patients with moderate-to-severe AD. Methods A total of 36 patients with moderate-to-severe AD were randomized (3 : 1) to ASN002 or placebo in the phase Ib study. Three dosage cohorts were studied over a 28-day period (20 mg, 40 mg and 80 mg once daily). RESULTS ASN002 was superior to placebo for the proportion of patients achieving Eczema Area and Severity Index (EASI) 50 (20 mg 20%, P = 0·93; 40 mg 100%, P = 0·003; 80 mg 83%, P = 0·03; placebo 22%), EASI 75 (20 mg 0%, P = 0·27; 40 mg 71%, P = 0·06; 80 mg 33%, P = 0·65; placebo 22%) and in change from baseline in pruritus (20 mg -1·3 ± 2·1, P = 0·81; 40 mg -3·1 ± 2·7, P = 0·27; 80 mg -4·7 ± 2·1, P = 0·01; placebo -1·6 ± 1·8). Adverse events were generally mild and similar across all groups. ASN002 showed dose-dependent plasma exposure with low interpatient variability, significantly downregulated several serum biomarkers involved in Th1, Th2 and Th17/Th22 immunity, and decreased the atherosclerosis-associated biomarker E selectin/SELE. CONCLUSIONS In patients with moderate-to-severe AD, ASN002 showed strong efficacy with rapid onset of action and associated improvements in systemic inflammation.

Abstract
BACKGROUND The results of the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial showed a statistically significant 29% prostate cancer mortality reduction for the men screened in the intervention arm and a 23% negative impact on the life-years gained because of quality of life. However, alternative prostate-specific antigen (PSA) screening strategies for the population may exist, optimizing the effects on mortality reduction, quality of life, overdiagnosis, and costs. METHODS Based on data of the ERSPC trial, we predicted the numbers of prostate cancers diagnosed, prostate cancer deaths averted, life-years and quality-adjusted life-years (QALY) gained, and cost-effectiveness of 68 screening strategies starting at age 55 years, with a PSA threshold of 3, using microsimulation modeling. The screening strategies varied by age to stop screening and screening interval (one to 14 years or once in a lifetime screens), and therefore number of tests. RESULTS Screening at short intervals of three years or less was more cost-effective than using longer intervals. Screening at ages 55 to 59 years with two-year intervals had an incremental cost-effectiveness ratio of $73000 per QALY gained and was considered optimal. With this strategy, lifetime prostate cancer mortality reduction was predicted as 13%, and 33% of the screen-detected cancers were overdiagnosed. When better quality of life for the post-treatment period could be achieved, an older age of 65 to 72 years for ending screening was obtained. CONCLUSION Prostate cancer screening can be cost-effective when it is limited to two or three screens between ages 55 to 59 years. Screening above age 63 years is less cost-effective because of loss of QALYs because of overdiagnosis.

Abstract
Since its introduction in 2003, DNA barcoding has proven to be a promising method for the identification of many taxa, including mosquitoes (Diptera: Culicidae). Many mosquito species are potential vectors of pathogens, and correct identification in all life stages is essential for effective mosquito monitoring and control. To use DNA barcoding for species identification, a reliable and comprehensive reference database of verified DNA sequences is required. Hence, DNA sequence diversity of mosquitoes in Belgium was assessed using a 658 bp fragment of the mitochondrial cytochrome oxidase I (COI) gene, and a reference data set was established. Most species appeared as well-supported clusters. Intraspecific Kimura 2-parameter (K2P) distances averaged 0.7%, and the maximum observed K2P distance was 6.2% for Aedes koreicus. A small overlap between intra- and interspecific K2P distances for congeneric sequences was observed. Overall, the identification success using best match and the best close match criteria were high, that is above 98%. No clear genetic division was found between the closely related species Aedes annulipes and Aedes cantans, which can be confused using morphological identification only. The members of the Anopheles maculipennis complex, that is Anopheles maculipennis s.s. and An. messeae, were weakly supported as monophyletic taxa. This study showed that DNA barcoding offers a reliable framework for mosquito species identification in Belgium except for some closely related species.

Abstract
In order to quantify the spatial and seasonal variations of sediment oxygen consumption and nutrient fluxes, we performed a spatial survey in the south west lagoon of New Caledonia during the two major seasons (dry and wet) based on a network of 11 sampling stations. Stations were selected along two barrier reef to land transects representing most types of sediments encountered in the lagoon. Fluxes were measured using ex-situ sediment incubations and compared to sediment characteristics. Sediment oxygen consumption (SOC) varied between 500 and 2000 micromol m(-2)h(-1), depending on season and stations. Nutrient effluxes from sediment were highly variable with highest fluxes measured in muddy sediments near the coast. Inter-sample variability was as high as seasonal differences so that no seasonally driven temperature effect could be observed on benthic nutrient fluxes in our temperature range. Nutrient fluxes, generally directed from the sediment to the water column, varied between -5.0 and 70.0 micromol m(-2)h(-1) for ammonia and between -2.5 and+12.5 micromol m(-2)h(-1) for PO(4) and NO(2+3). SOC and nutrient fluxes were compared to pelagic primary production rates in order to highlight the tight coupling existing between the benthic and pelagic compartments in this shallow tropical lagoon. Under specific occasions of low pelagic productivity, oxygen sediment consumption and related carbon and nutrient fluxes could balance nearly all net primary production in the lagoon. These biogeochemical estimates point to the functional importance of sediment biogeochemistry in the lagoon of New Caledonia.

Abstract
Killer cell immunoglobulin-like receptors (KIRs) belong to a diverse family of natural killer (NK) cell receptors recognizing human leukocyte antigen (HLA) class I molecules. Due to this functional link, KIR molecules are expected to display a high polymorphism, such as their HLA ligands. Moreover, many studies conducted in mouse and human models have shown that NK-KIR receptors play an important role in haematopoietic stem cell transplantation (HSCT). A beneficial impact of peculiar KIR ligand (HLA) mismatching has been reported suggesting a role to this combinatory HLA-KIR polymorphism. It is thus important to investigate KIR diversity in various human populations. To this end, we used polymerase chain reaction-sequence-specific primers to evaluate KIR gene in five selected populations (France, Guadeloupe, Senegal, Finland and Réunion). Genotypic and haplotypic frequencies were computed, as well as genetic distances and dendrogram (phylip package). These data illustrate the genetic relationship of these five populations through the KIR polymorphism. Results revealed a wide diversity in KIR gene frequencies in Guadeloupe and Réunion, and a high specificity in Senegal. The obtained dendrogram indicated small genetic distances between France, Guadeloupe and Réunion as well as between France and Finland. Senegal showed a distant genetic relationship with the other countries and, interestingly, an inverted ratio of coding/non-coding (KIR2DS4/1D) alleles compared with Caucasians. These data expose the broad diversity in KIR genes worldwide and show that KIR genes are pertinent tools in human population genetics. If the role of KIR donor-recipient incompatibilities is confirmed, KIR diversity according to ethnicity should be taken into account during the selection of HSCT donors.

Abstract
Temozolomide, an oral DNA methylator that inactivates the DNA repair enzyme O(6)-alkylguanine-DNA alkyltransferase (AGAT), has demonstrated anticancer activity on protracted schedules. Protracted schedules may lead to an 'autoenhancement' of temozolomide's inherent cytotoxic potential by cumulative reduction of the cell's capacity for AGAT-mediated DNA repair and resistance. This study was undertaken to characterise AGAT inactivation and regeneration in the peripheral blood mononuclear cells (PBMCs) of patients treated on two protracted temozolomide schedules. O(6)-alkyl guanine-DNA alkyltransferase activity was measured in the PBMCs of patients treated on two phase I protracted temozolomide studies. Patients were treated daily for either 7 days every 2 weeks (Schedule A) or 21 days every 4 weeks (Schedule B). The effects of various temozolomide doses (75-175 mg m(-2)), treatment duration (7-21 days), and temozolomide plasma levels on AGAT inactivation and regeneration, as well as the relation between AGAT inactivation and toxicity, were studied. O(6)-alkyl guanine-DNA alkyltransferase activity in PBMCs was measured serially in 52 patients. Marked inactivation of AGAT occurred following 7 days of temozolomide treatment, with mean AGAT activity decreasing by 72% (P<0.0001). Similarly, mean AGAT activity decreased by 63 and 73% after 14 and 21 days of treatment, respectively (P<0.001 for both comparisons). O(6)-alkyl guanine-DNA alkyltransferase inactivation was greater after 7 days of treatment with higher doses of temozolomide than lower doses and remained markedly reduced 7 days post-treatment. However, AGAT inactivation following temozolomide treatment for 14 and 21 days was similar at all doses. On the continuous 21-day schedule, AGAT inactivation was significantly greater in patients who experienced severe thrombocytopenia than those who did not (90.3+/-5.5 vs 72.5+/-16.1%, P<0.045). In conclusion, protracted administration of temozolomide, even at relatively low daily doses, leads to significant and prolonged depletion of AGAT activity, which may enhance the antitumour activity of the agent.

Abstract
Study of Band Broadening occurring in Size Exclusion Chromatography (SEC) is reported using very narrow PS standards obtained and characterised by Temperature Gradient Interaction Chromatography (TGIC). Chromatograms are fitted by Exponentially Modified Gaussian functions (EMG) and mapping of band broadening is obtained for different column sets. Interpretation of the skewing of the chromatograms is proposed with a new model using Brownian motion properties inside the pores. That explains why band broadening and tailing become so important near total exclusion volume.

Abstract
PURPOSE To assess the feasibility of administering OSI-774, to recommend a dose on a protracted, continuous daily schedule, to characterize its pharmacokinetic behavior, and to acquire preliminary evidence of anticancer activity. PATIENTS AND METHODS Patients with advanced solid malignancies were treated with escalating doses of OSI-774 in three study parts (A to C) to evaluate progressively longer treatment intervals. Part A patients received OSI-774 25 to 100 mg once daily, for 3 days each week, for 3 weeks every 4 weeks. Part B patients received OSI-774 doses ranging from 50 to 200 mg given once daily for 3 weeks every 4 weeks to establish the maximum tolerated dose (MTD). In part C, patients received this MTD on a continuous, uninterrupted schedule. The pharmacokinetics of OSI-774 and its O-demethylated metabolite, OSI-420, were characterized. RESULTS Forty patients received a total of 123 28-day courses of OSI-774. No severe toxicities precluded dose escalation of OSI-774 from 25 to 100 mg/d in part A. In part B, the incidence of severe diarrhea and/or cutaneous toxicity was unacceptably high at OSI-774 doses exceeding 150 mg/d. Uninterrupted, daily administration of OSI-774 150 mg/d represented the MTD on a protracted daily schedule. The pharmacokinetics of OSI-774 were dose independent; repetitive daily treatment did not result in drug accumulation (at 150 mg/d [average]: minimum steady-state plasma concentration, 1.20 +/- 0.62 microg/mL; clearance rate, 6.33 +/- 6.41 L/h; elimination half-life, 24.4 +/- 14.6 hours; volume of distribution, 136. 4 +/- 93.1 L; area under the plasma concentration-time curve for OSI-420 relative to OSI-774, 0.12 +/- 0.12 microg/h/mL). CONCLUSION The recommended dose for disease-directed studies of OSI-774 administered orally on a daily, continuous, uninterrupted schedule is 150 mg/d. OSI-774 was well tolerated, and several patients with epidermoid malignancies demonstrated either antitumor activity or relatively long periods of stable disease. The precise contribution of OSI-774 to these effects is not known.

Abstract
Prostate cancer lends itself ideally to chemoprevention due to a number of specific features of the disease. These include a high prevalence, long latency time, hormone dependency, the availability of an ideal marker (prostate serum antigen) and, last but not least, the availability of a defined precursor lesion (prostatic intraepithelial neoplasia) among the pathways leading to clinical disease. The large variability in the incidence of the tumor in different geographical regions suggests the possibility of nutritional influences regarding the stimulation and/or inhibition of clinical cancer, as there is a similar prevalence worldwide of the precursor lesion. A great number of publications have dealt with a number of nutritional factors, including fat, phytoestrogens, vitamins (especially vitamin E) and minerals such as selenium and calcium. These are among the most reported substances with a possible influence on disease development; however, unfortunately there are no conclusive results or study outcomes at present which satisfy accepted standards of evidence. Ongoing studies on nutrition and prostate cancer may bring the required evidence to support what is still only an hypothesis at present.

Abstract
OBJECTIVES To evaluate the efficacy, tolerability, endocrinological effects and the pharmacokinetics of Casodex, when given as monotherapy during daily dosing of 10-200 mg to patients with advanced prostate cancer. METHODS A total of 390 patients with advanced prostate cancer were treated for a minimum of 12 weeks with a daily monotherapy dose of Casodex. The doses ranged from 10 to 200 mg. Objective assessments of efficacy included: review of measurable metastases, prostate dimension, prostatic acid phosphatase and prostate-specific antigen (PSA) levels. Subjective assessments of efficacy included review of urological symptoms, performance status, bone scan and analgesic requirement. Pharmacokinetic samples were taken at various time points up to 3 months, and assayed using an achiral HPLC method. RESULTS Clear objective responses were observed, particularly at doses of 50 mg and above. Specifically, the median percentage decrease in PSA at 50 mg was 90.0%, and at 100 and 200 mg it was 93.4 and 94.8%, respectively. Up to 53% of symptomatic patients demonstrated a subjective response at 3 months. Casodex was well tolerated at all doses with no effect on haematological or cardiovascular parameters and no effect on renal function. The expected pharmacological effects of potent antiandrogen therapy, such as breast tenderness (58%), gynaecomastia (48%), and hot flushes (17%), were reported, but these incidences reflected the direct eliciting of these events. The intrinsic efficacy of Casodex was demonstrated despite increases of 60% in testosterone levels. However, this increase reached a plateau after 4-12 weeks of therapy, but the majority of values remained within the normal range. Casodex has a half-life of approximately 1 week, enabling once-daily dosing with no effect of age or renal impairment on its pharmacokinetics. CONCLUSION Casodex has a favourable side effect profile compared with the known safety profiles of other antiandrogens and has demonstrated intrinsic efficacy. Casodex warrants further investigation as a monotherapy for the management of advanced prostate cancer.

Abstract
INTRODUCTION AND OBJECTIVES The EORTC conducted two randomized phase III trials of maximal androgen blockade (MAB) in 695 patients with metastatic prostate cancer. Trial 30,843 compared orchidectomy or buserelin to buserelin plus cyproterone acetate and showed no significant difference in survival while trial 30,853 showed that Zoladex plus flutamide had a significantly longer survival than orchidectomy. Reasons for this discrepancy were sought. METHODS In order to determine whether differences in patient characteristics could explain these possibly contradictory results, a Cox proportional hazards regression model was used to identify prognostic factors for survival in each study. Patients were divided into risk groups (good or poor prognosis with 3.5 and 1.75 years' median survival, respectively) based on their alkaline phosphatase, hemoglobin, performance status, pain score, T category and G grade at entry on study. RESULTS The survival advantage of MAB in 30,853 was limited to patients with a good prognosis (164/302 (54%) of the patients). In 30,843, only 93/337 patients (28%) had a good prognosis so there were insufficient data to draw separate conclusions in these patients. Despite the limitations of subgroup analyses, these results show that patients in 30,843 had on the average a worse prognosis than patients in 30,853. Hence there were fewer good prognosis patients who could potentially benefit from MAB, thus providing one possible explanation for the overall negative conclusion. CONCLUSIONS These studies once again underline the importance of taking into account patient characteristics when designing and interpreting metastatic prostate cancer trials. They also provide criteria which may be used to define risk groups as part of a protocol's patient eligibility criteria. In the design of future trials assessing MAB, a sufficient number of good prognosis patients should be entered to reliably assess treatment efficacy in this subgroup.

Abstract
The International Consultation on Urological Diseases (ICUD), under the cosponsorship of the World Health Organization (WHO), the International Society of Urology (SIU), and the International Union Against Cancer (UICC), is active in the organization of global consultations on urological diseases. The major urological associations from the five continents (the American Urological Association (AUA), the Urological Association of Asia (UAA), the Confederation Americana Urologia (CAU), and the European Association of Urology (EAU)), together with societies with expertise in specific programs such as the International Continence Society, the International Society for Impotence Research, the International Prostate Health Council, the American Cancer Society, the International Union Against Cancer, and the European Organization for Research and Treatment of Cancer, came together in the late 1980s on the basis of their proven record in organizing successful international meetings on urological cancer to initiate the concept of the ICUD. At the suggestion of the WHO, a First International Consultation on Benign Prostatic Hypertrophy (BPH) was organized in 1991, not only to provide recommendations to medical practitioners but also to define and plan future research on the subject. The formula, based on global multiprofessional collaboration and expertise, exceeded expectations, and other consultations were to follow, e.g., on prostate cancer, incontinence, erectile dysfunctions, and nosocomial infections. In 1994 it became necessary to establish a legal nongovernmental organization to foster the goals of the ICUD, essentially for the creation of awareness, knowledge, and recommendations on the diagnosis and treatment of urological diseases.

Abstract
Isoflavonoids, flavonoids and lignans are natural oestrogenic compounds derived from soya, tea, fruits and vegetables and they have been proposed as chemopreventive agents in Asian men, in whom the incidence of prostate cancer is much lower than in men from the West. In addition to their weak oestrogenic activity, oestrogen antagonistic activity has also been described for some of these compounds. Furthermore, the lignan, enterolactone and the soya-derived isoflavone genistein are inhibitors of several steroid metabolising enzymes, such as aromatase, 5alpha-reductase and 17beta-hydroxysteroid dehydrogenase. Genistein is a potent inhibitor of tyrosine kinases and along with flavonoids such as kaempferol and apigenin is also an inhibitor of topoisomerases I and II, enzymes which are crucial to cellular proliferation. Genistein is also an inhibitor of angiogenesis and many experimental in vivo and in vitro models, including those for prostate cancer, are growth inhibited by isoflavonoids, flavonoids and lignans. It is estimated that the traditionally eating Japanese male consumes approximately 20 mg of isoflavones per day, whereas for Western men, the daily consumption would be less than 1 mg/day. This is reflected in a high mean plasma concentration of genistein (180 ng/ml, n = 72) in Japanese men, compared to a level of <10 ng/ml for Western males.

Abstract
Asian men have much lower incidences of prostate cancer and possibly of benign prostatic hyperplasia (BPH) than their Western counterparts. Vegetarian men also have a lower incidence of prostate cancer than omnivorous males. Both Asian and vegetarian men consume low-fat, high-fibre diets which provide a rich supply of weak dietary oestrogens. These plant or phyto-oestrogens have been proposed as chemopreventive agents, particularly for Asian men and to a lesser extent, for vegetarian men also. The three principal classes of phyto-oestrogens are the isoflavonoids, flavonoids and lignans. Many foods of plant origin contain varying amounts of these compounds and hundreds of plants manifest some degree of oestrogenic activity. Soya, a dietary staple in many parts of Asia, is a major source of the isoflavonoids, daidzein and genistein. Flavonoids are present in high concentration in many fruits, vegetables and crop species. In particular, apigenin and kaempferol are regarded as major flavonoids because of their common occurrence in plants, and their significant concentrations when present. Apples, onions and tea-leaves are excellent sources of flavonoids. Plant lignans are present in many cereals, grains, fruits and vegetables, and give rise to the mammalian lignans, enterodiol and enterolactone; however, the richest source is linseed (flaxseed) and other oilseeds. In addition to their oestrogenic activity, many of these plant compounds can interfere with steroid metabolism and bioavailability, and also inhibit enzymes, such as tyrosine kinase and topoisomerase, which are crucial to cellular proliferation.

Abstract
BACKGROUND Mepartricin, a semisynthetic polyene derivative with a favorable effect on urethro-prostatic function, was clinically evaluated, adopting the diagnostic and research criteria recommended by the First International Consultation on BPH. METHODS A multicenter, randomized, double-blind, parallel-group study compared mepartricin 40 mg/daily to placebo in the treatment of 196 patients with newly diagnosed BPH and mild-to-moderate symptomatology. International Prostate Symptom Score (I-PSS), quality of life (QoL) index and maximum urinary flow-rate (Qmax) were determined every 4 weeks for 6 months; postvoiding volume, prostate volume, and prostate-specific antigen (PSA) were assessed after 3 and 6 months of therapy. RESULTS Mepartricin was shown to determine a statistically significant improvement over placebo in I-PSS and QoL index from month 2 onwards, and a significant linear increase in Qmax over the study period. At month 6, the improvement in the mepartricin and placebo groups in I-PSS, QoL index, and Qmax was 6.3 (standard error (SE) 0.51) and 4.2 (SE 0.60) points (P = 0.003), 0.99 (SE 0.14) and 0.62 (SE 0.12) points (P = 0.036), and 2.7 (SE 0.46) and 1.2 (SE 0.46) ml/sec (P = 0.051), respectively. No significant differences were noted in postvoiding residual volume, prostate volume, or PSA. Mepartricin tolerability was good, showing no adverse events on sexual function. CONCLUSIONS Mepartricin proved to be an effective treatment of benign prostatic hyperplasia, determining an improvement in symptoms, quality of life, and peak urinary flow.

Abstract
Both benign hyperplasia (BPH) and cancer of the prostate are manifest in men beyond the age of 50. Approximately 50% of men greater than 50 years of age will suffer from the symptoms associated with BPH, especially from bladder outlet obstruction. With the ever-increasing proportion of the population over 65 years of age worldwide, BPH is becoming an important medical problem as the world moves into the next millennium. Cancer of the prostate is the second most commonly diagnosed cancer after skin cancer in the male population of the United States, and the second most common cause of death from cancer after that of the lung. Overall, around the world the incidence of carcinoma of the prostate is increasing annually by 2-3%. Both race and geographical location have a profound influence of the prevalence of prostate cancer worldwide. Black men in the USA have the highest incidence, while the incidence is much lower in Asian men from China, Japan and Thailand. Although the prostate gland is androgen-dependent, it is now recognized that the biological actions of endocrine-related factors, such as androgens, oestrogens, glucocorticoids and certain dietary and environmental factors, are mediated within the gland by various growth regulatory factors. The growth regulatory factors such as epidermal growth factor (EGF), keratinocyte growth factors (KGF), fibroblast growth factors (FGFs) and insulin-like growth factors II and I are mitogenic and directly stimulate cell proliferation under the modulating influence of steroid hormones. Steroids are therefore essential but not directly responsible for cell proliferation. Certain plant compounds such as isoflavonoids, flavonoids and lignans have been proposed as cancer protective compounds in populations with low incidences of prostate diseases. In particular, soya contains the isoflavone genistein, a compound with many properties which could influence both endocrine and growth factor signalling pathways.
