Abstract
The medial prefrontal cortex (mPFC) and β-adrenoceptors (βARs) have been implicated in modulating anxiety-like behavior. However, the specific contributions of the β2-AR subtype in mPFC in anxiety are still unclear. To address this issue, we used optogenetic and microRNA-based (miRNA) silencing to dissect the role of β2-AR in mPFC in anxiety-like behavior. On the one hand, we use a chimeric rhodopsin/β2-AR (Opto-β2-AR) with in vivo optogenetic techniques to selectively activate β2-adrenergic signaling in excitatory neurons of the mPFC. We found that opto-activation of β2-AR is sufficient to induce anxiety-like behavior and reduce social interaction. On the other hand, we utilize the miRNA silencing technique to specifically knock down the β2-AR in mPFC excitatory neurons. We found that the β2-AR knock down induces anxiolytic-like behavior and promotes social interaction compared to the control group. These data suggest that β2-AR signaling in the mPFC has a critical role in anxiety-like states. These findings suggest that inhibiting of β2-AR signaling in the mPFC may be an effective treatment of anxiety disorders.

Abstract
Extensive scholarship has demonstrated that communities of color, low-income communities, and Indigenous communities face greater environmental and health hazards compared to communities with more White or affluent people. Low-income, Indigenous, Black, and/or other populations of color are also more likely to lack access to health care facilities, healthy food, and adequate formal education opportunities. Despite the mountains of evidence that demonstrate the existence and significance of the elevated toxic social and environmental exposures experienced by these communities, the inclusion of these factors into chemical evaluations has been scarce. In this paper, we demonstrate a process built with publicly available data and simple geospatial techniques that could be utilized by the U.S. Environmental Protection Agency (USEPA) to incorporate cumulative approaches into risk assessments under the Toxic Substances Control Act. The use of these approaches, particularly as they relate to identifying potentially exposed and susceptible subpopulations, would help USEPA develop appropriate risk estimates and mitigation strategies to protect disproportionately burdened populations from the adverse effects of chemical exposures. By utilizing such approaches to inform risk evaluation and mitigation, USEPA can identify and protect those most burdened and impacted by toxic chemicals, and finally begin to close the gap of environmental health inequities.

Abstract
Background Industrial food animal production (IFAP) is characterized by dense animal housing, high throughput, specialization, vertical integration, and corporate consolidation. Research in high-income countries has documented impacts on public health, the environment, and animal welfare. IFAP is proliferating in some low- and middle-income countries (LMICs), where increased consumption of animal-source foods has occurred alongside rising incomes and efforts to address undernutrition. However, in these countries IFAP’s negative externalities could be amplified by inadequate infrastructure and resources to document issues and implement controls. Methods Using UN FAOSTAT data, we selected ten LMICs where food animal production is expanding and assessed patterns of IFAP growth. We conducted a mixed methods review to explore factors affecting growth, evidence of impacts, and information gaps; we searched several databases for sources in English, Spanish, and Portuguese. Data were extracted from 450+ sources, comprising peer-reviewed literature, government documents, NGO reports, and news articles. Results In the selected LMICs, not only has livestock production increased, but the nature of expansion appears to have involved industrialized methods, to varying extents based on species and location. Expansion was promoted in some countries by explicit government policies. Animal densities, corporate structure, and pharmaceutical reliance in some areas mirrored conditions found in high-income countries. There were many reported weaknesses in regulation and capacity for enforcement surrounding production and animal welfare. Global trade increasingly influences movement of and access to inputs such as feed. There was a nascent, compelling body of scientific literature documenting IFAP’s negative environmental and public health externalities in some countries. Conclusions LMICs may be attracted to IFAP for economic development and food security, as well as the potential for increasing access to animal-source foods and the role these foods can play in alleviating undernutrition. IFAP, however, is resource intensive. Industrialized production methods likely result in serious negative public health, environmental, and animal welfare impacts in LMICs. To our knowledge, this is the first systematic effort to assess IFAP trends through an environmental public health lens for a relatively large group of LMICs. It contributes to the literature by outlining urgent research priorities aimed at informing national and international decisions about the future of food animal production and efforts to tackle global undernutrition.

Abstract
Although the introduction of antiretroviral therapy has rendered HIV a chronic illness, inconsistent engagement in HIV care by key populations limits its public health impact. Poor engagement in care is especially prevalent among vulnerable populations with mental health and substance use disorders. Beyond structural and health system considerations, psychosocial factors may present challenges to sustained engagement. We conducted a qualitative study using in-depth interviews with 31 primarily African American, urban-based individuals, many with past or current drug use and mental disorders, living with HIV. Participants identified several psychosocial barriers that detract from their motivation to attend appointments and take medication. These included mental distress or detachment over a lack of purpose in life; denial about the need to be engaged in care; insufficient trust in the efficacy of care or the health system; deaths of loved ones leading to bereavement or loss of social support; and engagement in specific avoidance behaviors like drugs and alcohol. The study findings suggest that more comprehensive HIV care, which integrates mental health and substance abuse services in order to enhance meaning and address coping and grief, may be important. Considering these services in addition to improving the logistical components of care such as cues/reminders, accessibility, and patient-provider communication may improve intervention packages.

Abstract
Background Increased insecticide-treated net (ITN) use over the last decade has contributed to dramatic declines in malaria transmission and mortality, yet residual transmission persists even where ITN coverage exceeds 80%. This article presents observational data suggesting that complex human net use patterns, including multiple entries to and exits from ITNs by multiple occupants throughout the night, might be a contributing factor. Methods The study included dusk-to-dawn observations of bed net use in 60 households in the Peruvian Amazon. Observers recorded number of net occupants and the time and number of times each occupant entered and exited each net. The study team then tabulated time of first entry, total times each net was lifted, and, where possible, minutes spent outside by each occupant. Results The sample included 446 individuals and 171 observed sleeping spaces with nets. Household size ranged from 2 to 24 occupants; occupants per net ranged from 1 to 5. Nets were lifted a mean 6.1 times per night (SD 4.35, range 1–22). Observers captured substantial detail about time of and reasons for net entry and exit as well as length of time and activities undertaken outside. Conclusions These findings suggest that the ITN use patterns observed in this study may contribute to residual transmission. As a result, respondents to net use surveys may truthfully report that they slept under a net the previous night but may not have received the anticipated protection. More research is warranted to explore the impact of this phenomenon. Concurrent entomological data would help assess the magnitude of the effect.

Abstract
Despite the existence of highly active antiretroviral therapy, HIV/AIDS morbidity and mortality continue to be public health burdens in the United States due to difficulties in engaging people living with HIV/AIDS (PLWHA) in continuous, effective care. In comparison to studies investigating patient-level characteristics associated with starting and remaining in care, there is relatively little research on how structural factors, such as those pertaining to healthcare providers and the infrastructure for delivery of health services, influence patients’ engagement in HIV care. Our study, based in the city of Baltimore, Maryland, uses qualitative research methods with a population of predominantly African American PLWHA who have a history of drug abuse, to examine facilitators and barriers regarding adherence to antiretroviral therapy (ART) and HIV care appointment attendance. Data collection involved conducting one-on-one, in-depth interviews with 31 study participants, and data analysis entailed thematic coding of interview transcripts and writing analytic memos to develop ideas and concepts. Among other findings, factors described as influential by our study participants related to appointment reminders and scheduling, the attitudes and communication styles of HIV clinicians, and the disposition and availability of other healthcare workers on the care “team.” Thus, improving quality of HIV care and means of delivering it may help mitigate the numerous points in the continuum of HIV care when a patient may disengage.

Abstract
Background Despite targeted indoor residual spraying (IRS) over a six-year period and free mass distribution of long-lasting insecticide-treated nets (ITNs), malaria rates in northern Ghana remain high. Outdoor sleeping and other night-time social, cultural and economic activities that increase exposure to infective mosquito bites are possible contributors. This study was designed to document these phenomena through direct observation, and to explore the context in which they occur. Methods During the late dry season months of February and March 2014, study team members carried out continuous household observations from dusk to dawn in one village in Ghana’s Northern Region and one in Upper West Region. In-depth interviews with health workers and community residents helped supplement observational findings. Results Study team members completed observations of 182 individuals across 24 households, 12 households per site. Between the two sites, they interviewed 14 health workers, six community health volunteers and 28 community residents. In early evening, nearly all study participants were observed to be outdoors and active. From 18.00-23.00 hours, socializing, night school, household chores, and small-scale economic activities were common. All-night funerals, held outdoors and attended by large numbers of community members, were commonly reported and observed. Outdoor sleeping was frequently documented at both study sites, with 42% of the study population sleeping outdoors at some time during the night. While interviewees mentioned bed net use as important to malaria prevention, observed use was low for both indoor and outdoor sleeping. Net access within households was 65%, but only 17% of those with access used a net at any time during the night. Participants cited heat as the primary barrier and reported higher net use during the rainy season. Discussion Outdoor sleeping and other night-time activities were extensive, and could significantly increase malaria risk. These findings suggest that indoor-oriented control measures such as ITNs and IRS are insufficient to eliminate malaria in this setting, especially given the low net use observed. Development and evaluation of complementary outdoor control strategies should be prioritized. A research agenda is proposed to quantify the relative risk of outdoor night-time activities and test potential vector control interventions that might reduce that risk.

Abstract
INTRODUCTION Research suggests that literacy plays a key role in mediating the relationship between formal education and care-seeking among women in developing countries. However, little research has examined literacy's role independently from formal education. This differentiation is important, as literacy programs and formal schooling entail distinct intervention designs and resources, and may target different groups. To assess the relationship between literacy and healthcare-seeking among Nepali women of low educational attainment, we analyzed data from the 2011 Nepal Demographic and Health Survey (DHS). METHODS From the 2011 Nepal DHS, our sample consisted of 7,020 women who had attained at most a primary school level of education, and a subsample of 4,875 women with no formal schooling whatsoever. We assessed associations between literacy and four healthcare-seeking outcomes: whether women identified "getting permission" as a barrier to accessing care; whether women identified "not wanting to go alone" as a barrier; whether among women who were married/partnered, the woman had some say in making decisions about her own health; and whether among women who experienced symptoms related to sexually-transmitted infections (STIs) in the past year, treatment was sought. We performed simple and multiple logistic regressions, which adjusted for several socio-demographic covariates. RESULTS Literacy was associated with some aspects of healthcare-seeking, even after adjusting for socio-demographic covariates. Among women with no more than primary schooling, literate women's odds of identifying "getting permission" as a barrier to healthcare were 23% less than illiterate women's odds (p = 0.04). For married/partnered women, odds of having some say in making decisions related to their health were 37% higher (p = 0.002) in literate than illiterate women. Comparing literate to illiterate women in the subsample with no formal schooling, odds of reporting "getting permission" as a barrier were 35% lower (p = 0.01), odds of having a decision-making say were 57% higher (p < 0.001), and odds of having sought care for experiences of STI-related symptoms were 86% higher (p = 0.04). CONCLUSIONS Further research should be undertaken to determine whether targeted literacy programs for those past normal schooling age lead to improved healthcare-seeking among Nepali women with little or no formal education.

Abstract
Acquired resistance to chemotherapy is the major obstacle to cure of small cell lung cancer (SCLC). Some of the most active drugs in the treatment of this tumor exert their cytotoxicity by interacting with the nuclear enzyme topoisomerase II (topo II), which in mammalian cells occurs in two isoforms, alpha and beta. We examined the relationship between levels of topo II alpha and beta and drug response in a panel of 25 unselected SCLC cell lines. Chemosensitivity to several topo II-interactive drugs, as well as other chemotherapeutic agents, was quantitated previously using a modified MTT assay. Topo II levels were determined by immunoblot analysis of whole cell lysates, with topo II alpha and beta isoform-specific antibodies, and results were expressed relative to levels found in NCI-H209 cells which had the highest topo II alpha in this series of cell lines. Levels of topo II alpha and beta mRNA were determined by Northern blotting. Pearson correlation analysis was used to determine the significance of the relationship between topo II alpha and beta levels and response to the various chemotherapeutic drugs, as well as the treatment history of the patients from whom the cell lines were derived. These analyses revealed an inverse correlation between topo II alpha levels and resistance to all of the tested drugs, including several drugs which are not known to interact with topo II. This correlation was statistically significant for doxorubicin, cisplatin, epirubicin, melphalan, nitrogen mustard, and vinblastine. With one exception (cisplatin), there were no significant correlations between topo II beta levels and drug response. There was no significant correlation between topo II alpha and beta levels and treatment history. Taken together, our results are consistent with the hypothesis that levels of topo II alpha are important determinants of drug response in SCLC.

Abstract
The 'wandering spleen' is a rare condition due to extreme laxity or absence of ligaments that fix the organ in its normal anatomical position within the left upper quadrant. Without early surgical intervention, wandering spleen can lead to torsion and subsequent splenic infarction or rupture. Clinical suspicion plus urgent investigation and intervention are important, so as to salvage the spleen and prevent complications. We present a case of torsion of a wandering spleen in a 21-year-old young woman, who presented with a painful pelvic mass. We also reviewed the literature on this entity.

Abstract
Intracranial aneurysm in twins is a rare clinical disease entity. Only 15 cases have been described in the literature. We report on a pair of identical twins with intracranial aneurysms. One presented with subarachnoid haemorrhage; digital subtraction angiography showed a left posterior communicating artery aneurysm, which was treated by coiling. The patient's twin sister was called for screening, whereupon digital subtraction angiography revealed a right ophthalmic internal carotid artery aneurysm that was treated conservatively.

Abstract
558 Background: Oral fluoropyrimidines such as C and UFT plus LV (U) are widely used pro-drugs dedicated to the care of CRC. Although their toxicity profile may slightly differ, no direct comparison between these treatments has been done as both molecules are converted into fluorouracil. To help the physicians to choose between C and U, we initiated this randomized cross-over trial aimed to assess patient's preference. Methods: Pts with advanced CRC received either a first cycle of C (1,250mg/m2 x 2/d for 14 days, q3 wks) or a first cycle of U (UFT 300mg/m2/d plus LV 75 mg/d in 3 divided doses every 8 hrs for 28 days, repeated at 35-day intervals). Patients were randomized to receive C at cycle 1 followed by U (arm A) or U at cycle 1 followed by C (arm B). After 2 cycles, pts were asked which treatment they preferred. Treatment was then continued with the chosen regimen. Preferences rates are presented with 95% confidence intervals and the two groups are compared with the chi-squared test. Results: 89 pts were enrolled from 10/2005 to 6/2010. Treatment arms were well balanced for baseline characteristics: male 57%; median age 66 years; PS 0-1 81%. Most of the pts were heavily pretreated (0/1/2/ and >2 previous chemotherapy lines: 6/2/15/66). 64 (arm A: 35, arm B: 29)/89 pts received at least 2 cycles of chemotherapy and were evaluable for preference. At cycle 1, 21% and 43% of the pts presented at least 1 severe toxic event with C and U, respectively. Pts with U at cycle 1 presented more likely with severe fatigue and anorexia. There was 1 toxic death under C (gr. 3 diarrhea, gr.4 neutropenia) at cycle 1. Overall, 66% (95%CI: 52-77%) of evaluable pts expressed preference for C, and there was a statistically significant difference between arms A and B (p<0.02) with more pts preferring C in arm A: 79% (95%CI: 61-91%), as compared to arm B: 50% (95%CI: 31-79%). Conclusions: Pts with advanced CRC preferred C over U, especially when given during the first cycle. No significant financial relationships to disclose.

Abstract
BACKGROUND AND PURPOSE N-methyl-D-aspartate (NMDA) receptors represent an attractive drug target for the treatment of neurological and neurodegenerative disorders associated with glutamate-induced excitotoxicity. The aim of this study was to map the binding domain of high affinity 5-substituted benzimidazole derivatives [N-{2-[(4-benzylpiperidin-1-yl)methyl]benzimidazol-5-yl}methanesulphonamide (XK1) and N-[2-(4-phenoxybenzyl)benzimidazol-5-yl]methanesulphonamide (XK2)] on the GluN2B subunit of the NMDA receptor. EXPERIMENTAL APPROACH The pharmacological antagonistic profiles of XK1 and XK2 were assessed using in vitro rat primary cerebrocortical neurones and two-electrode voltage clamp on Xenopus oocytes expressing heterologous GluN1/GluN2B receptors. Direct ligand binding was determined using the recombinant amino-terminal domain (ATD) of GluN2B. KEY RESULTS XK1 and XK2 effectively protected against NMDA-induced excitotoxicity in rat primary cortical neurones. Low concentrations of XK1 (10 nM) and XK2 (1 nM) significantly reversed neuronal death. Both compounds failed to inhibit currents measured from oocytes heterologously expressing GluN1-1a subunit co-assembled with the ATD-deleted GluN2B subunit. XK1 and XK2 showed specific binding to recombinant protein of GluN2B ATD with low nanomolar affinities. Several residues in the recombinant ATD of GluN2B were identified to be critical for conferring XK1 and XK2 sensitivity. The inhibitory effects of XK1 and XK2 were pH-sensitive, being increased at acidic pH. CONCLUSIONS AND IMPLICATIONS These results demonstrate that XK1 and XK2 are effective neuroprotective agents in vitro and indicate that 5-substituted benzimidazole derivatives inhibit GluN1/GluN2B receptors via direct binding to the ATD of the GluN2B subunit. These compounds represent valuable alternatives to the classical antagonist ifenprodil as pharmacological tools for studying GluN2B-containing NMDA receptors.

Abstract
Accurate estimates of stress in an atherosclerotic lesion require knowledge of the material properties of its components (e.g., normal wall, fibrous plaque, calcified regions, lipid pools) that can only be approximated. This leads to considerable uncertainty in these computational predictions. A study was conducted to test the sensitivity of predicted levels of stress and strain to the parameter values of plaque used in finite element analysis. Results show that the stresses within the arterial wall, fibrous plaque, calcified plaque, and lipid pool have low sensitivities for variation in the elastic modulus. Even a +/- 50% variation in elastic modulus leads to less than a 10% change in stress at the site of rupture. Sensitivity to variations in elastic modulus is comparable between isotropic nonlinear, isotropic nonlinear with residual strains, and transversely isotropic linear models. Therefore, stress analysis may be used with confidence that uncertainty in the material properties generates relatively small errors in the prediction of wall stresses. Either isotropic nonlinear or anisotropic linear models provide useful estimates, however the predictions in regions of stress concentration (e.g., the site of rupture) are somewhat more sensitive to the specific model used, increasing by up to 30% from the isotropic nonlinear to orthotropic model in the present example. Changes resulting from the introduction of residual stresses are much smaller.

Abstract
BACKGROUND AND OBJECTIVES Anti-Uz, a scarce antibody, defines a glycophorin B high-incidence antigen, which is protease-sensitive. In a few years, we have encountered 12 antibodies of similar specificity, made by Black individuals of the S- s+ U+ phenotype. MATERIALS AND METHODS Antibodies were characterized by serological methods, with common and rare MNS types, as well as red cells treated with various proteases. RESULTS Anti-U-like, mostly an autoantibody, was of IgG class and reacted optimally by indirect antiglobulin test at 20 degrees C. The corresponding antigen was destroyed by several proteases. Tests with papain-treated or Dantu+ cells suggested the existence of several subspecificities. CONCLUSION Anti-U-like is common in the African population, though its reactions are often misinterpreted. The fact that antibody producers are always Black patients remains unexplained. No relationship with a pathological state could be established.

Abstract
The Rapid Translation System (RTS 500) (Roche Molecular Biochemicals) is a high-yield protein expression system that utilizes an enhanced E. coli lysate for an in vitro transcription/translation reaction. In contrast to conventional transcription/translation, this system allows protein expression to continue for more than 24 h. We demonstrated the utility of the RTS 500 by expressing different soluble and active proteins that generally pose problems in cell-based expression systems. We first expressed GFP-lunasin, a fusion protein that, because of its toxicity, has been impossible to produce in whole cells. The second protein we expressed, human interleukin-2 (IL-2), is generally difficult to produce, either as the native molecule or as a GSTfusion protein, in a soluble form in bacteria. Finally, we demonstrated the capacity of the RTS 500 to co-express proteins, by the simultaneous production of GFP and CAT in a single reaction. This new technology appears to be particularly usefulfor the convenient production of preparative amounts (100-900 microg) of proteins that are toxic or insoluble in cell-based systems.

Abstract
Circulating osteocalcin is a good marker of osteoblastic activity and decreases significantly after stressful physiological states such as major surgery. Glucocorticoids are known to inhibit osteoblastic activity and result in a decline in circulating osteocalcin. We used etomidate to inhibit the cortisol response to routine gynaecological surgery to determine if this would prevent the postoperative decline in osteocalcin. Twenty-four patients were allocated randomly to receive either thiopental or etomidate for induction of anaesthesia; all other aspects of anaesthesia and perioperative management were standardized. In the thiopental group, circulating cortisol increased significantly at 2 and 6 h after the start of surgery and plasma osteocalcin concentrations decreased significantly to almost 50% of baseline values at 48 h. Etomidate abolished the cortisol response to surgery, and circulating osteocalcin concentrations did not change after operation. There was a significant difference in osteocalcin concentration between the groups at 48 h. We conclude that the cortisol response to surgery is associated with a postoperative decrease in circulating osteocalcin.

Abstract
BACKGROUND The mammalian lignans enterolactone and enterodiol are produced in the colon by the action of bacteria on the plant precursor secoisolariciresinol diglycoside, which is found in high concentrations in flaxseed. OBJECTIVE Two experiments were conducted to determine 1) whether there is a dose response in urinary lignan excretion with increasing flaxseed intake, 2) whether flaxseed processing affects lignan excretion, 3) peak plasma lignan concentrations, and 4) plasma lignan concentrations after chronic supplementation. DESIGN Nine healthy young women supplemented their diets with 5, 15, or 25 g raw or 25 g processed (muffin or bread) flaxseed for 7 d during the follicular phase of their menstrual cycles. Twenty-four-hour urine samples were collected at baseline and on the final day of supplementation. As an adjunct to the 25-g-flaxseed arm, subjects consumed the supplement for an additional day and blood and urine samples were collected at specific intervals. All blood and urine samples were analyzed for enterolactone and enterodiol by gas chromatography-mass spectroscopy. RESULTS A dose-dependent urinary lignan response to raw flaxseed was observed (r = 0.72, P < 0.001). The processing of flaxseed as a muffin or bread did not affect the quantity of lignan excretion. Plasma lignan concentrations were greater (P < or = 0.05) than baseline by 9 h after flaxseed ingestion (29.35+/-3.69 and 51.75+/-7.49 nmol/L, respectively). The total plasma area under the curve was higher on the eighth than on the first day (1840.15+/-343.02 and 1027.15+/-95.71 nmol x h/L, respectively). CONCLUSION Mammalian lignan production from flaxseed precursors is dependent on time and dose but not on processing.

Abstract
We have investigated contamination of extradural catheters during normal handling with starch powdered gloves. In the laboratory, extradural catheters were handled in sterile fields with both powdered and non-powdered gloves, simulating preparation for patient insertion. The catheters together with glove samples were then examined using a Zeiss 940 scanning electron microscope. Microscopy of samples revealed starch contamination of the catheters handled with powdered gloves, especially in the side hole areas. We conclude that extradural catheters may be contaminated easily by starch powder from surgical gloves. This powder may then be deposited into the extradural space. The effect of starch in the extradural space is not known but starch is known to cause inflammatory and granulomatous reactions in other parts of the body as well as being directly allergenic. Powder contamination of catheters may be avoided easily by the use of powder-free gloves and we feel that these should be used whenever possible.

Abstract
A novel NADPH-dependent enoyl reductase, catalyzing the conversion of 1-cyclohexenylcarbonyl coenzyme A (1-cyclohexenylcarbonyl-CoA) to cyclohexylcarbonyl-CoA, was purified to homogeneity from Streptomyces collinus. This enzyme, a dimer with subunits of identical M(r) (36,000), exhibits a Km of 1.5 +/- 0.3 microM for NADPH and 25 +/- 3 microM for 1-cyclohexenylcarbonyl-CoA. It has a pH optimum of 7.5, is most active at 30 degrees C, and is inhibited by both divalent cations and thiol reagents. Two internal peptide sequences were obtained. Ansatrienin A (an antibiotic produced by S. collinus) contains a cyclohexanecarboxylic acid moiety, and it is suggested that the 1-cyclohexenylcarbonyl-CoA reductase described herein catalyzes the final reductive step in the conversion of shikimic acid into this moiety.

Abstract
We describe a phase I-II study of two consecutive 5-day courses of a three-drug regimen of ifosfamide (IFM), carboplatin (CBDCA), and either etoposide (VP-16) (regimen 1) or teniposide (VM-26) (regimen 2) in high doses together with autologous bone marrow transplantation (ABMT), for previously treated patients with ovarian carcinoma (OC), germ cell tumors (GCT), gestational trophoblastic disease (GTD), or oat cell carcinoma (OCC). Forty-four patients entered the study. Two patients with OC received regimen 1, and 22 were given regimen 2. Sixteen patients with GCT, two with GTD, and two with OCC were treated with regimen 1. Six patients (13%) died of toxicity. Nephropathy and esophagitis were the dose-limiting toxic effects. The maximum-tolerated doses (MTDs) were 1,500 and 200 mg/m2/d for 5 days for IFM and CBDCA, respectively, in combination with VP-16 250 mg/m2/d for 5 days (regimen 1), and 150, 1,500, and 200 mg/m2/d for 5 days for VM-26, IFM, and CBDCA, respectively (regimen 2). The response rate of patients with OC was 78% (complete response [CR], 14%). For patients previously resistant to chemotherapy, the response rate was 70%. There were no long-term disease-free survivors among patients with OC. The response rate of patients with GCT was 60% (CR, 33%). All responders with GCT were resistant to previous chemotherapy. Unmaintained CRs lasted 2, 6, 8+, 27+, and 37+ months. Of the two patients with GTD, one with previous resistance to chemotherapy attained a CR of 18+ months. One patient with OCC attained a CR lasting 6 months. The regimen possesses great antitumor activity. It produced CRs of long duration in a number of patients with GCT and GTD who were previously resistant to chemotherapy.

Abstract
Eleven obese volunteers took part in a 12-week study during 8 weeks of which 2 meals of their control 1000 kcal diets were replaced by a soya based liquid formula (1 month) or a milk based liquid formula (1 month). The mean weight loss per month was 2.5 kg (P less than 0.05). On the soya formula total and LDL cholesterol levels were reduced significantly over the month by 10.0 +/- 2.7% (P less than 0.01) and 17.5 +/- 5.6% (P less than 0.02), respectively. Neither the milk based formula or the control low calorie diet lowered serum cholesterol significantly over the diet period. No change was seen in serum triglycerides on any of the 3 diets. No difference was seen between treatments in 24-h urinary C-peptide excretion. The results indicated that use of a vegetable protein supplement in a weight loss program which induced moderate weight loss was associated with a reduction in blood lipids, whereas moderate weight loss on a control low calorie diet or milk based formula was not.

Abstract
HLA immunization is a common complication of transfusion therapy in 30% to 60% of oncohematologic patients. Evidence shows that leukocytes present in cellular blood products are the main component involved in the occurrence of HLA immunization, and several studies showed that leukocyte-poor blood products are less able to induce it. However, leukocyte-poor platelet concentrates obtained by conventional techniques, ie, centrifugation, frequently have a high level of remaining leukocytes. Cotton wool filter Imugard IG 500 can be used to obtain leukocyte-poor cellular blood products. The technique is easy to perform, even in an emergency, and can be used with either packed RBCs or platelet concentrates. Means of 97%, 92%, and 76% elimination of leukocytes are obtained for packed RBCs, pooled standard platelet concentrates, and single-donor platelet concentrates, respectively. Patients were randomized to receive either standard (control group) or filtered (leukocyte-poor group) blood products. Of 112 randomized patients, 69 were evaluable, 35 in the control group and 34 in the leukocyte-poor group. Both groups are comparable according to age, diagnosis, sex ratio, previous transfusions, and pregnancies. There is a significant difference in regard to the HLA immunization rate (31.4% in the control v 11.7% in the leukocyte-poor group, P less than .05) and frequency of refractoriness to platelet transfusions (46.6% v 11.7%, P less than .05). We conclude that this filtration technique can be an efficient means to reduce the HLA immunization rate in polytransfused oncohematologic patients.
