Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
Coastal cities in tropical areas are often low-lying and vulnerable to the effects of flooding and storms. San Juan, Puerto Rico is a good example of this. It is built around a lagoon-channel complex called the San Juan Bay Estuary (SJBE). A critical channel in the estuary, the Caño Martín Peña, has filled in and now frequently floods the surrounding communities with sewage-enriched waters, causing a series of human health and ecological problems. Sediment core analyses indicate that portions of the SJBE now function as settling basins. High urban and sewage runoff to the Caño contributes nitrogen (N), but stable isotope and sediment nutrient analyses indicate that this runoff may also enhance conditions for coupled sulfate reduction-nitrogen fixation. The amount of 'new' bioavailable N created from inert atmospheric N2 gas may meet or exceed that from the runoff into the Caño Martín Peña. The ecological consequences of this appear to extend beyond the ponded channel, potentially contributing to the poor water quality of the SJBE, greater than contaminated runoff alone.

Abstract
Dementia prevention is highly important. Improved control of vascular risk factors has the potential to decrease dementia risk, but may be difficult. Therefore, we developed and piloted a care management protocol for Veterans at risk for dementia. We enrolled 32 Veterans with diabetes and hypertension, at least one of which was poorly controlled, and cognitive impairment. Participants were randomly assigned to a 6-month care management intervention or to usual care. At enrollment, 6-months and 12-months, we assessed cognitive performance, mood, and diabetes and hypertension control. At follow-up, diastolic blood pressure was lower in intervention participants at 6 months (p=.041) and 12 months (p=.022); hemoglobin A1c, global mental status and mood did not differ between groups. Recall of a distractor list (p=.006) and logical memory long-delay recall (p=.036) were better at 6 months in the intervention group (p=.006). Care management may contribute to improved control of dementia risk factors.

Abstract
Statins are widely used lipid-lowering drugs that are effective in reducing cardiovascular disease risk. Although they are generally well tolerated, they can cause muscle toxicity, which can lead to severe rhabdomyolysis. Research in this area has been hampered to some extent by the lack of standardized nomenclature and phenotypic definitions. We have used numerical and descriptive classifications and developed an algorithm to define statin-related myotoxicity phenotypes, including myalgia, myopathy, rhabdomyolysis, and necrotizing autoimmune myopathy.

Abstract
The influence of food intake on the bioavailability of isoniazid (INH) has been examined in nine healthy male volunteers. INH was administered as a single oral dose, both in fasting state and together with a standardized breakfast. Numerous venous blood samples were obtained 5 min-6 hours after the INH ingestion, and the concentrations of unmetabolized INH in serum were assessed by spectrophotometry. The observations indicate that both the peak concentration and the total amount of INH absorbed are greatly reduced when the drug is ingested together with food. Hence it is recommended that, in the treatment of tuberculosis with INH, the drug should be given on an empty stomach. The data may also have some bearing on the use of INH for assessing acetylation rates and estimating dosages of hydralazine and related drugs.

The serum levels of quinidine after single oral doses and after long-term treatment have been compared with the serum levels after administration of some other quinidine preparations on the Swedish market. The side-effects of the sustained release preparations have also been studied. Results indicated that this new sustained release quinidine preparation yields more even serum concentrations of quinidine and seemed to cause less troublesome side-effects than the marketed preparations.

Abstract
Three patients are described in whom malignant ventricular arrhythmias appeared in connection with a reinfarction some days after hospitalization for an acute myocardial infarction and in whom massive doses of procainamide, up to 7.5 g/day i.v., were necessary to prevent these arrhythmias. The serum concentration of procainamide was 2--4 times higher than the recommended upper level, but no side-effects were observed. With the dose given, one would have expected still higher serum concentrations. Several reasons for this finding are discussed, including the effects of renal function, intestinal leakage, storage of the drug in tissues and hitherto unknown metabolic pathways of procainamide in patients, who are slow acetylators.

Abstract
Maxiletine, a new drug effective in the treatment of ventricular arrhythmias, was given to 20 patients for approximately 2 years. The study was designed to investigate the nature and prevalence of side-effects during long-term therapy, and the degree of correlation between such effects and the serum levels of the drug. The methodology used to determine the serum level is described. Mexiletine was well tolerated and serious side-effects were not seen. In particular, antinuclear factor was not detected during the treatment period. The serum level of mexiletine was easily maintained within the therapeutic range, and most side-effects correlated closely with the drug level. Mexiletine appears to be an effective alternative to currently available antiarrhythmic agents.

Abstract
OBJECTIVE Evaluate effectiveness of weight-loss interventions in a managed care setting. METHODS Three-arm randomized clinical trial: usual care, mail, and phone intervention. Participants were 1801 overweight managed care organization (MCO) members. Measures included baseline height, weight at baseline and 24 months, self-reported weight at 18 months. Intervention and participation in other weight-related programs was monitored across 24 months. RESULTS Weight losses were 2.2, 2.4, and 1.9 kg at 18 months in the mail, phone, and usual care groups, respectively. Mail and phone group weight changes were not significantly different from usual care (P<0.35). Weight losses at 24 months did not differ by condition (0.7 kg mail, 1.0 kg phone, and 0.6 kg usual care, P=0.55). Despite treatment availability over 24 months, participation diminished after 6 months. Participation was a significant predictor of outcomes in the mail and phone groups at 18 months and the mail group at 24 months. Cost-effectiveness of phone counseling was $132 per 1 kg of weight loss with mail and usual care achieving similar cost-efficiency of $72 per 1 kg of weight loss. CONCLUSION Although mail- and phone-based weight-loss programs are a reasonably efficient way to deliver weight-loss services, additional work is needed to enhance their short- and long-term efficacy.

Abstract
BACKGROUND Changing patterns of care for terminally ill people mean that 90% of patients in the UK now spend the majority of their last year of life at home. It is now widely accepted that supporting individuals to die at home relies heavily on the availability of family carers to provide the majority of the care needed. However, one of the most common reasons for unplanned admissions near the end of life is carers' inability to provide continuing care. One strategy to overcome these challenges has been to offer planned respite care. Despite recent studies, in reality little is known about respite services for patients with life limiting illness, in particular how respite is experienced by the caregivers or to what extent respite services address their needs. METHODS This prospective study, comprising mixed methods of data collection, explored the experiences of 25 family carers whose relative had been admitted to the local hospice for inpatient respite care. Semi-structured interviews were conducted at two time points: pre- and post-respite. The Relative Stress Scale Inventory was administered at both interviews. RESULTS Just over half of the sample were caring for a relative with a diagnosis of cancer (n=13); the majority of the others had a number of neurological conditions (n = 12). The data demonstrate that managing care for relatives with a life limiting illness was perceived to be hard work, both physically and mentally. Inpatient respite care was considered important as it enabled family carers to have a break from the ongoing care-giving responsibilities, as well as being an opportunity to experience 'normal life' independently. The majority of family carers felt that their expectations of respite for themselves had been achieved. The respite service was well evaluated in relation to: standard of nursing care; alternative facilities on offer, atmosphere; and other care homes. DISCUSSION Currently, inpatient respite services are provided to two patient groups--those in the last year of life and those with a chronic life limiting illness. However, on closer analysis, the current model of service delivery, a two-week inpatient stay, may not be best suited to those caring for a relative in the last year of life. Similarly, it might be questioned whether an inpatient hospice is the most suitable setting for those patients needing supportive care, rather than specialist palliative care. The study has raised many issues that need to be considered in the support of carers caring for relatives with a life limiting illness with uncertain trajectories.

Abstract
The mechanisms of carcinogenesis in nervous tissues are not well understood. It is now established that adenosine 3,',5'-cyclic monophosphate (cAMP)-pathway plays a crucial role in initiating differentiation in transformed and embryonic cells of neuronal and glial origin. Therefore, we propose that defects in the cAMP-pathway may initiate the first phase of carcinogenesis (immortalization). Subsequent genetic abnormalities in oncogenes, anti-oncogenes or other cellular genes individually or in combination may lead to transformation (cancer phenotype). This hypothesis is derived from the fact that an elevation of the cAMP level in murine NB cells induces terminal differentiation in many of these cells in spite of the fact that they are highly aneuploid. Additional changes in cAMP-regulated genes responsible for initiating differentiation may make these cells resistant to cAMP or may make the cAMP-effect on differentiation reversible. Indeed, cAMP-resistant cells exist in NB cell populations, and the cAMP-effect on differentiation is reversible in glioma cells. Identification of genes that initiate, promote and maintain terminal differentiation and those which prevent differentiation following elevation of cAMP in NB cells may increase our understanding of the mechanisms of carcinogenesis. This review illustrates the following: (a) historical background leading to the discovery of cAMP as an inducer of differentiation in nerve cells; (b) identification of potential sites in cAMP-pathway that may play a crucial role in initiating the first phase of carcinogenesis (immortalization) and potential gene targets in immortalized cells whose alterations may cause neoplastic transformation of nerve cells. It is interesting to note that the cAMP pathway remains responsive to an elevated cAMP level in inducing differentiation in NB cells in spite of chromosomal anomalies and genetic changes associated with the maintenance of a cancer phenotype.

Abstract
Antigen-specific lymphocytes are important in the immune response to viral infection. Peripheral blood mononuclear cells (PBMC) are traditionally used as a source of effector cells in most immunological studies. We described here the use of the bispecific monoclonal antibodies (BSMAB) anti CD3:CD8 (CD3,8) and anti CD3:CD4 (CD3,4B) to expand and selectively enrich CD4+ and CD8+ T cells populations, respectively. The expanded cells demonstrated >90% CD3+CD4+ or CD3+CD8+ by 14 days. We measured HIV- and CMV-specific responses of these subset-enriched T cell and found that sensitivity and specificity is similar or higher when compared to PBMC in various cellular immunology assays (CMI). Vbeta analysis of BSMAB-enriched cells demonstrated comparable repertoire to the parent PBMC. Although both CD45RA(hi) and CD45RO(hi) cell populations were expanded with the BSMAB, selective subset depletion demonstrated that the antigen-specific T cell responses were restricted to the initial CD45RO(hi) memory effector subgroup. In conclusion, BSMAB in vitro enrichment of T cells allows significant expansion of the cell population without loss of specificity. This technique of cell expansion permits studies of T cell subset function in situations where the initial cell source is scarce, and presents an alternative for viable and functional T cells in immunological assays.

Abstract
Municipal solid wastes are major sources of air, water and soil contamination. There is a need for alternative waste management techniques to better utilize the waste and minimize its adverse environmental impact. A two-phase pilot-scale bio-fermentation system was used to evaluate the feasibility of producing methane from grass waste, a major constituent of solid wastes. The bi-phasic system consists of a solid phase and a methane phase. Leachate is re-circulated through the solid phase until a desired level of volatile fatty acid (VFA) is accumulated in the leachate. The leachate is then transferred to the methane reactor where the VFA is converted to methane. The results showed that 67% of the volatile solids in the waste can be converted into soluble chemical oxygen demand in a period of six months. The system produced an average of 0.15 m3 of methane per kg of grass. The average methane concentration in the produced gas was 71%. A mathematical model was developed to estimate the methane and carbon dioxide concentrations in the gas phase as a function of reactor properties.

Abstract
Recent studies have shown that progressive supranuclear palsy (PSP) could be inherited, but the pattern of inheritance and the spectrum of the clinical findings in relatives are unknown. We here report 12 pedigrees, confirmed by pathology in four probands, with familial PSP. Pathological diagnosis was confirmed according to recently reported internationally agreed criteria. The spectrum of the clinical phenotypes in these families was variable including 34 typical cases of PSP (12 probands plus 22 secondary cases), three patients with postural tremor, three with dementia, one with parkinsonism, two with tremor, dystonia, gaze palsy and tics, and one with gait disturbance. The presence of affected members in at least two generations in eight of the families and the absence of consanguinity suggests autosomal dominant transmission with incomplete penetrance. We conclude that hereditary PSP is more frequent than previously thought and that the scarcity of familial cases may be related to a lack of recognition of the variable phenotypic expression of the disease.

Abstract
Ondansetron 4 mg was compared with metoclopramide 10 mg for prevention of post-operative nausea and emesis in in-patients undergoing major gynaecological surgery in this double-blind, randomized, placebo-controlled, multicentre study. A total of 1044 patients received a single intravenous (i.v.) injection of study medication immediately before induction of anaesthesia. Nausea and emesis were assessed over the 24 h post-operative period. Significantly more patients who received ondansetron experienced no emetic episodes (44%) compared with those who received metoclopramide (37%, P = 0.049) or placebo (25%, P < 0.001). No nausea was experienced by significantly more patients who received ondansetron (32%) than with patients who received metoclopramide (24%, P = 0.009) or placebo (16%, P < 0.001). In addition, fewer emetic episodes, less severe nausea and a reduced need for rescue antiemetics were also observed with ondansetron (P < 0.05 vs. metoclopramide and placebo). Metoclopramide and placebo-treated patients were also 1.5 times (95% Cl 1.5-4.2) and 2.5 times (95% Cl 1.1-2.0) more likely, respectively, to experience nausea post-operatively. Overall, ondansetron was the most effective antiemetic in this patient population.

Abstract
1. Contracting for Safety (CFS) has become an integral part of nursing practice but never has been subjected to scientific scrutiny. 2. Clinical reasons for avoiding the use of contracting with some patient populations exist, including that some patients may construe CFS as a failure of empathy by the caregiver. 3. CFS can, in some instances, be helpful in establishing a therapeutic relationship or aiding in assessment, but never should be the sole basis for determining a patient's lethality.

Abstract
1. Oxidation of benzo[a]pyrene (BP) by I2 in the presence of AgClO4 in benzene generates the BP.+ClO4-.AgI complex. This same method was used to produce radical cations from 6-FBP, 6-ClBP, 6-BrBP and 6-CH3BP. 2. Reaction of the BP, 6-FBP, 6-ClBP and 6-BrBP radical cation perchlorates with H2O produced BP 1,6-, 3,6- and 6,12- dione, whereas 6-CH3BP.+ClO4-.AgI yielded 6-CH2OHBP. 3. When BP.+ClO4-.AgI and 6-FBP.+ClO4-.AgI were reacted with NaOAc in H2O/CH3CN (9:1), 6-OAcBP was formed, in addition to the quinones. In the case of 6-ClBP.+ClO4-.AgI, a small amount of 1-OAc-6-ClBP and 3-OAc-6-ClBP was formed in addition to the diones, whereas for 6-BrBP and 6-CH3BP the reaction products were BP diones and 6-CH2OHBP respectively. 4. These results confirm the localization of charge in the BP.+ at C-6, followed by C-1 and C-3. 5. The reaction of BP with NOBF4 in CH2Cl2 produced BP.+BF4-, radical cation free of complexation with inorganic salts. 6. Reaction of BP.+BF4- with DNA produced the depurinating adducts BP-6-C8Gua, BP-6-C8dGua and BP-6-N7Gua.

Abstract
Metabolic activity in cardiac tissue slices from the guinea pig (GP), the rat (RT), the nonhibernating summer and winter hedgehog (SH and WH), respectively, was determined at 20 degrees and at 37 degrees C from their rates of heat production, P, (units, W/g tissue) by direct and indirect calorimetry. Energy-linked transport of Na+ and K+ in the tissues was determined from changes in metabolic rate induced by specific inhibition of the Na/K pump, the functional expression of Na/K-ATPase, the pacemaker enzyme in energy production assigned the role of transporting Na+ and K+ out of and into the cell. The results indicate a higher rate of energy production and utilization in the cardiac tissue of the hedgehog than in that of the nonhibernators, the rat and the guinea pig, at both temperatures. At 37 degrees C the rate at which the cardiac tissue from the hedgehog consumed oxygen was as much as six times that registered for the guinea pig. The temperature coefficients of P and of the Na/K pump in the tissues from the two groups of hedgehogs were significantly higher than in the tissues from the rat and the guinea-pig (P < 0.001). The determined metabolic indices, the basal rate of heat production P, the rate of oxygen consumption, P(O2) in thermal units (W/g tissue), and the Na/K-pump capacity (PC) indicate species-specific differences between the animals. Both PC and its variation with temperature, delta PC/delta T(o)C, were in the order WH > SH > RT > GP. These results indicate that the hedgehog's cardiac tissue, in comparison with that of the nonhibernators, has a greater capacity to generate energy in general and for active transport of Na+ and K+ at 37 degrees C after exposure to a lower temperature. A role is suggested for the Na/K-ATPase and some other unique rate-limiting enzymes in the metabolic pathway for the observed differences in temperature tolerance and cardiac performance between hibernators and nonhibernators.

Abstract
OBJECTIVE To ascertain the prevalence and type of psychiatric morbidity present in HIV infected patients presenting for the first time to a specialty HIV medical clinic. Also, to develop a way of screening for psychiatric cases in this setting using established self-report questionnaires. METHOD Fifty patients who presented consecutively for medical care at the Johns Hopkins Hospital General HIV Clinic participated in this study. These patients were first screened using the General Health Questionnaire and the Beck Depression Inventory and subsequently underwent a comprehensive neuropsychiatric evaluation. RESULTS Fifty-four percent were found to suffer from a psychiatric disorder with an additional 22 percent from an active substance use disorder. These rates are one-and-one-half to two times higher than those reported from other medical clinics. The GHQ and BDI used together as screens could identify psychiatric "cases" with a sensitivity of 81 percent and a specificity of 61 percent, an efficacy similar to that found in other clinics. CONCLUSIONS Given the high prevalence of psychiatric disorders in HIV infected patients presenting for medical care, screening, evaluating, and treating for these disorders is crucial and should be pursued systematically. This is best done through the presence of a psychiatric team within HIV medical clinics rather than in affiliation with such clinics.

Abstract
Fifty-four cobalt-chrome alloy femoral heads were retrieved at revision surgery or at post-mortem; 23 came from uncemented, eight from hybrid and 23 from cemented hip arthroplasties. The uncemented and hybrid implants had porous coating, metal backing and modular femoral heads; with one exception none of the cemented implants had any of these. Twenty-five of the 31 heads from uncemented and hybrid arthroplasties, and 11 of the 23 heads from cemented arthroplasties showed surface damage involving more than 25% of the surface. Scanning electron microscopy revealed multidirectional fine scratches 1 micron to 10 microns in depth and width which appeared to have been made by fine, hard particles. There was a higher rate of such damage in the uncemented and hybrid arthroplasties than in the cemented implants, suggesting that the abrasive particles were mainly released from the metal, rather than from the cement or polyethylene components of the implants.

Abstract
In a consecutive series of admissions to the Johns Hopkins Sexual Disorders Unit, 4 out of 20 patients appeared to have simulated paraphilic symptoms that further assessment indicated were either exaggerated or not present. The paper presents case histories of these 4 patients. A descriptive comparison is made between these patients and control groups of patients who admitted having paraphilic symptoms and a group of patients accused of having paraphilic symptoms but who denied them. Patients who simulated paraphilias tended to be self-referred (75%) and without current legal charges (100%). None of these patients was referred or sought treatment for pedophilia, in contrast to the other two patient groups, in which pedophilia accounted for 75% of the referrals. Several possible explanations for why patients might simulate paraphilias and implications for therapists who evaluate or treat sex offenders are discussed.

A Plasmodium falciparum antigen gene coding for a 220-kD glutamate-rich protein (GLURP) has been cloned, and the 783 C-terminal amino acids of this protein (GLURP489-1271) have been expressed as a beta-galactosidase fusion protein in Escherichia coli. The encoded 783 amino acid residues contain two areas of repeated amino acid sequences. Antibodies against recombinant GLURP489-1271, as well as against a synthetic peptide corresponding to GLURP899-916, and against a synthetic peptide representing the major glutamate rich repeat sequence from the P. falciparum ring erythrocyte surface antigen (Pf155/RESA) (EENV)6 were examined in 423 individuals (age range 30 days-78 years) living in a malaria holoendemic area of Liberia. In the 5-9-year-old age group, subjects with anti-GLURP489-1271 antibody concentrations greater than the mean value of the group had lower parasite densities than those with low antibody concentrations (P = 0.0151). High levels of anti-GLURP899-916 antibodies did not correlate with low parasite densities. However, high levels of anti-(EENV)6 antibodies were associated with significantly lower parasite densities in the 2-4-year-old age group (P = 0.0189). There was no correlation between the anti-GLURP489-1271 and anti-(EENV)6 antibody responses. The data provide indirect evidence for a protective role of antibodies reacting with recombinant GLURP489-1271 as well as with the synthetic peptide (EENV)6 from the Pf155/RESA.

Abstract
The effects of hemorrhagic shock and retransfusion on the activities of two endogenous antioxidant enzymes, catalase and superoxide dismutase, were studied in male New Zealand white rabbits. Following instrumentation and stabilization, blood was withdrawn to reduce mean arterial pressure to 35 mmHg (SHOCK). After 60 min of shock, the warmed autologous blood was infused and the animals were allowed to recover for an additional 30 min (RETRANS). CONTROL animals were instrumented but not bled or transfused. A 60 min period of hemorrhagic shock had no significant effect on tissue or plasma activities of catalase or superoxide dismutase. However, transfusion following hemorrhagic shock resulted in an increase in catalase activity of nearly two-fold in the liver and five-fold in the small intestine. In contrast, superoxide dismutase activity remained unchanged after retransfusion in other tissues and in plasma. These results indicate that superoxide dismutase and catalase activities may be preserved or even induced following transfusion for hemorrhagic shock.

Abstract
Two of 25 healthy pet sooty mangabey (SM) monkeys (Cercocebus atys) living in West Africa were seropositive by immunoblot when surveyed for antibody to simian immunodeficiency virus of macaques (SIVmac). SIVsmLIB1 was isolated from one of the pet sooty mangabeys. Nucleotide sequence data showed that this isolate is a member of the SIVsm/human immunodeficiecy virus type 2 (HIV-2)/SIVmac group of primate lentiviruses. Furthermore, sequence comparisons revealed extensive genetic diversity among SIVsm isolates similar to that observed previously in SIV isolates from naturally infected African green monkeys. These observations provide additional evidence for monkey-human cross-species transmission of SIVsm as the source of HIV-2 infection of human.

Abstract
The effect of cadralazine and its active metabolite CGP 22639 on the covalent binding reaction of C4 and C3 has been studied. Trypsin-Sepharose was used to activate radio-labelled C3 and C4 and binding of the radio-labelled protein to the trypsin-Sepharose was measured. Cadralazine inhibited 50% of the binding of C3 and C4 at concentrations of 19 mmol/l and 15 mmol/l, respectively. Its active metabolite was more potent and inhibited 50% of the C3 and C4 binding at concentrations of 8 and 3.5 mmol/l, respectively. These concentrations are much higher than those found in plasma during therapy. This is consistent with the clinical observation that in patients with normal kidney function cadralazine is not an inducer of SLE.

Abstract
Thirty-four asbestos workers, with either asbestosis, diffuse pleural thickening, calcified pleural plaques, or with comparable asbestos exposure but no evidence of asbestos-related disease and seven normal controls underwent a progressive exercise test. The subjects were categorized on the basis of lung function tests and PA chest X-rays. During the exercise test oxygen saturation was measured continuously by an ear lobe oximeter. The asbestosis and diffuse pleural thickening groups showed significant oxygen desaturation on exertion, confirming that both these conditions give rise to appreciable respiratory disability.

Abstract
Stable human hybridomas were generated that produced inhibitory anti-Plasmodium falciparum monoclonal antibodies. Peripheral blood lymphocytes, obtained from adults in Liberia, a malaria endemic area, were immortalized with Epstein-Barr virus and then fused with KR4, a human, lymphoblastoid cell line. Stable hybridomas that produced anti-P. falciparum monoclonal antibody were identified by an ELISA assay that used the trophozoite and schizont antigens of both the Honduras I and FCR3 parasite strains. Monoclonal antibodies produced by selected hybridomas derived from lymphocytes of two individuals were subsequently studied. The anti-parasite antibodies were produced at 1-3 micrograms/ml in culture supernatants. All of the monoclonal antibodies bound specifically to trophozoites and schizonts of both strains of parasite in an indirect immunofluorescence assay and inhibited production of ring stage parasites by more than 90% when added to trophozoite or schizont containing erythrocytes in culture. Western immunoblot analysis of antigens obtained from trophozoites and schizonts (parasite age span of 36 to 48 h) was performed using either affinity purified or ammonium sulfate-concentrated monoclonal antibody. Antibody from three hybridomas which bound primarily to antigens of the Honduras 1 strain had Mr of approximately 140,000, 130,000 and 123,000.

Abstract
The metabolism of hydralazine (1-hydrazinophthalazine hydrochloride, Apresoline) was investigated in 17 hypertensive patients of known acetylator status who were chronically treated with oral doses of 50 mg b.i.d. or 100 mg b.i.d. hydralazine. The acetylator status was assessed either by the monoacetyldapsone/dapsone ratio or by the isoniazide plasma half-life. In each patient the tests were performed on two different days of treatment and they included the analyses of four hydralazine metabolites (NAc-HPZ, 3OH-MTP, MTP and TP), as well as apparent hydrazine in urine and also the determination of plasma concentrations of apparent hydralazine. All data of the two experiments performed within an interval of at least five days were in good agreement, thus indicating that the patients were in pharmacokinetic steady states. No correlation was detectable between any of the determined amounts of metabolites of hydralazine and the assigned acetylator status of the patients. On the other hand the rank order of the urinary yields of the two main metabolites NAc-HPZ and 3OH-MTP suggest to be a representative scale for the patients' status in respect to the biotransformation of the drug itself. The urinary yield of apparent hydrazine is dependent on the pH applied during the analyses and is not correlated with any of the other data recorded. The findings of the present study support the assumption that measuring a relevant prominent metabolite of the drug itself may lead to a more reliable assessment of the particular metabolic status of the patients than by classification through a non treatment related foreign compound.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Unit dose and traditional drug distribution systems were compared in a 352-bed long-term-care facility by analyzing nursing time, medication-error rate, medication costs, and waste. Time spent by nurses in preparing, administering, charting, and other tasks associated with medications was measured with a stop-watch on four different nursing units during six-week periods before and after the nursing home began using unit dose drug distribution. Medication-error rate before and after implementation of the unit dose system was determined by patient profile audits and medication inventories. Medication costs consisted of patient billing costs (acquisition cost plus fee) and cost of medications destroyed. The unit dose system required a projected 1507.2 hours less nursing time per year. Mean medication-error rates were 8.53% and 0.97% for the traditional and unit dose systems, respectively. Potential annual savings because of decreased medication waste with the unit dose system were $2238.72. The net increase in cost for the unit dose system was estimated at $615.05 per year, or approximately $1.75 per patient. The unit dose system appears safer and more time-efficient than the traditional system, although its costs are higher.

Abstract
Two hundred and eighty-two children, two to nine years old, were included in a prospective three-year study in four villages with holoendemic malaria. In three villages the children received monthly doses of either chloroquine, pyrimethamine or chlorproguanil respectively for two years. In the fourth, vitamin tablets were used as placebo. Presumptive treatment with chloroquine (10 mg base kg-1) was given to all children with fever of suspected malarial origin. The two-year drug distribution was satisfactorily fulfilled to 168 children. Surveys, including physical and laboratory examinations were performed every six months, four weeks after medication. A fifth village was only visited at the start of the study and after two years. The mean crude parasite rate was initially 92%. Plasmodium falciparum was the main species. Splenomegaly was recorded in all children. In the chloroquine-treated children, the parasite rates varied between 30% and 50% during the study. By the end of the second year the spleen rate was reduced from 100% to 50%. Reported episodes of fever were reduced to half and mean haematocrit levels increased by 6% in comparison with children receiving the placebo. Total IgG concentrations were reduced from 36.7 g l-1 to 25.9 g l-1, whereas no significant decrease was observed in malarial seropositivity as measured by indirect immunofluorescence. Chlorproguanil had a weaker impact on parasitaemia with parasite rates between 50% and 90%. However, the spleen rate was reduced to 67% and there was a significant reduction of reported fever episodes. Mean haematocrits increased by 4%. Total IgG decreased from 31.8 g l-1 to 23.8 g l-1. In contrast, in the pyrimethamine group, the placebo group and the untreated group from the fifth village, the malariometric indices after two years were comparable to each other and to the initial values. During the third year only presumptive chloroquine treatment was given, and by the end of the study all malariometric indices were again comparable. From clinical observations there was no apparent impairment of protective immunity to malaria from the two years of regular distribution of the drugs. We conclude that a certain degree of malaria control could be achieved in Liberian children by the administration of monthly doses of chloroquine 10 mg base kg-1. The administration of chlorproguanil (1.5 mg kg-1) represents an alternative regimen.
