Abstract
BACKGROUND BEECH investigated the efficacy of capivasertib (AZD5363), an oral inhibitor of AKT isoforms 1-3, in combination with the first-line weekly paclitaxel for advanced or metastatic estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer, and in a phosphoinositide 3-kinase, catalytic, alpha polypeptide mutation sub-population (PIK3CA+). PATIENTS AND METHODS BEECH consisted of an open-label, phase Ib safety run-in (part A) in 38 patients with advanced breast cancer, and a randomised, placebo-controlled, double-blind, phase II expansion (part B) in 110 women with ER+/HER2- metastatic breast cancer. In part A, patients received paclitaxel 90 mg/m2 (days 1, 8 and 15 of a 28-day cycle) with capivasertib taken twice daily (b.i.d.) at two intermittent ascending dosing schedules. In part B, patients were randomly assigned, stratified by PIK3CA mutation status, to receive paclitaxel with either capivasertib or placebo. The primary end point for part A was safety to recommend a dose and schedule for part B; primary end points for part B were progression-free survival (PFS) in the overall and PIK3CA+ sub-population. RESULTS Capivasertib was well tolerated, with a 400 mg b.i.d. 4 days on/3 days off treatment schedule selected in part A. In part B, median PFS in the overall population was 10.9 months with capivasertib versus 8.4 months with placebo [hazard ratio (HR) 0.80; P = 0.308]. In the PIK3CA+ sub-population, median PFS was 10.9 months with capivasertib versus 10.8 months with placebo (HR 1.11; P = 0.760). Based on the Common Terminology Criteria for Adverse Event v4.0, the most common grade ≥3 adverse events in the capivasertib group were diarrhoea, hyperglycaemia, neutropoenia and maculopapular rash. Dose intensity of paclitaxel was similar in both groups. CONCLUSIONS Capivasertib had no apparent impact on the tolerability and dose intensity of paclitaxel. Adding capivasertib to weekly paclitaxel did not prolong PFS in the overall population or PIK3CA+ sub-population of ER+/HER2- advanced/metastatic breast cancer patients.ClinicalTrials.gov: NCT01625286.

Abstract
Abstract
Background: E17K is the most common activating AKT1 mutation and was shown to be a therapeutic target in this multipart Phase 1 study of AZD5363 (NCT01226316), an oral and selective pan-AKT kinase inhibitor, in patients (pts) with AKT1-mutant (AKT1m) advanced solid tumors. In heavily pretreated AKT1m (E17K) ER+ metastatic breast cancer (MBC) pts, monotherapy achieved an objective response rate (ORR) of 20% and a median progression-free survival of 5.5 months (95% CI, 2.9−6.9). Suppression of PI3K-AKT signaling results in induction of ER-dependent transcription, potentially limiting the response to single-agent PI3K/AKT inhibitors. We explored the hypothesis that simultaneous inhibition of AKT and ER signaling would enhance antitumor efficacy in AKT1m ER+ MBC.
Methods: In an expansion of this study, we administered oral AZD5363 400 mg twice daily, 4 days on 3 days off, and fulvestrant 500 mg, to AKT1m (detected in tumor tissue by local screening and/or plasma BEAMing) ER+ HER2– MBC pts, enrolled into a fulvestrant-naïve (FN) or fulvestrant-resistant (FR) cohort (max 24 pts/cohort). Key objectives included safety and efficacy by RECIST v1.1. We report results of a planned interim analysis conducted when 12 pts/cohort reached maturity for assessment of 24-week clinical benefit rate (CBR), defined as the percentage of responders plus those with stable disease (SD) ≥24 weeks.Data cut-off occurred in June 2017.
Results: At the time of analysis, 24 AKT1m pts (23 E17K, 1 E40K) had received treatment. FN had more visceral disease (83.3% vs 66.7%) and ER+/PR– status (25% vs 8.3%) than FR. Median number of prior anticancer regimens was 4.5 (range 1–9) and 6 (2–11) in FN and FR, respectively, with more chemotherapy (CT) and less hormone therapy (HT) exposure in FN vs FR [3 (0–5) vs 2 (0–6) and 2 (0–4) vs 4 (2–6) prior CT and HT, respectively]. Prior palbociclib was received by 1 (8.3%) and 4 (33.3%) pts in FN and FR, respectively. Clinical efficacy is detailed below; CBR was 33% and 42% in FN and FR, respectively (Table 1). There was 1 unconfirmed partial response in patients treated with prior palbociclib and 3 SD. At data cut-off, 18 pts had discontinued treatment: progressive disease, n=12; adverse events (AEs), n=2; other reasons, n=4. AEs were observed in all 24 pts, most commonly diarrhea (71%), nausea (63%), vomiting and decreased appetite (29%). Grade ≥3 AEs occurred in 13 (54%) pts, most frequently maculopapular rash (n=3), nausea, hyperglycemia and back pain (all n=2). Dose reduction due to AEs occurred in 3 pts.
Table 1. Clinical efficacy FNFREligible for interim data cut-off, n1212ORR, n (%)2 (17)4 (33)CBR, n (%)4 (33)5 (42)Confirmed response (complete/partial response), n (%)2 (17)4 (33)SD ≥24 weeks, n (%)2 (17)1 (8)
Conclusions: AZD5363 plus fulvestrant is clinically active in AKT1m ER+ MBC pts, including in pts with demonstrated prior resistance to fulvestrant. Comparatively lower efficacy was observed in the FN cohort; factors that may have potentially contributed (eg disease characteristics) will be explored. cfDNA and genomic data will also be presented.

Abstract
This article outlines the progress of a newly-commissioned three year study known as Network 1000. It is a three-year project funded through the Community Fund and is being carried out by the University of Birmingham on behalf of Vision 2020. The project’s aim is to create a panel survey of 1000 visually-impaired people to be interviewed regularly over the three-year period, and hopefully beyond, enabling their changing needs and circumstances to be monitored over time. The findings will be used to influence policy-makers and service-providers, and will also be disseminated to a wider audience of people with an interest in visual impairment. Building on the longitudinal nature of the project enables the project team to develop a methodology that is both democratic and inclusive. The underlying research philosophy is one of inclusion and participation and in this respect the people this research affects the most - those who are visually impaired - are involved in all stages of the research process. People with a visual impairment have played a key role in generating the data and the themes that will drive the construction of the main survey instrument. The article is divided into five sections that describe the progress of the project to date: first, it briefly outlines the background to the project; second, it describes the underlying philosophy behind the democratic approach to inclusion and participant involvement; third, it presents preliminary results from generative interviews; fourth, it discusses how the team will recruit participants to the project with particular reference to the two-stage sample design that has been adopted; and finally, it describes how this two-stage approach will be operationalized. The article concludes by outlining the next phase of the project and with a short reflection on the research process to date.

Abstract
We report a case of disseminated fatal Talaromyces (Penicillium) marneffei infection in an HIV-infected, antiretroviral treatment-experienced South African woman who had travelled to mainland China. The 37-year-old woman was admitted to a private hospital in fulminant septic shock and died within 12 h of admission. Intracellular yeast-like bodies were observed on the peripheral blood smear. A serum cryptococcal antigen test was negative. Blood cultures flagged positive after 2 days; on direct microscopy, yeast-like bodies were observed and a thermally dimorphic fungus, confirmed as T. marneffei, was cultured after 5 days. The clinical features of HIV-associated disseminated penicilliosis overlap with those of tuberculosis and endemic deep fungal infections. In the southern African context, where systemic opportunistic fungal infections such as cryptococcosis are more common among HIV-infected patients with a CD4+ count of <100 cells/µL, this infection is not likely to be considered in the differential diagnosis unless a travel history is obtained.

Abstract
BACKGROUND Increased sensitivity and exposure to stress are associated with psychotic symptoms in schizophrenia and its risk states, but little is known about the co-evolution of stress sensitivity and exposure with positive and other symptoms in a clinical high-risk (CHR) cohort. METHOD A combined cross-sectional and longitudinal design was used to examine the associations over time of stress sensitivity and exposure (i.e. life events) with 'prodromal' symptoms in a cohort of 65 CHR patients assessed quarterly for up to 4 years, and at baseline in 24 healthy controls similar in age and gender. RESULTS Impaired stress tolerance was greater in patients, in whom it was associated over time with positive and negative symptoms, in addition to depression, anxiety and poor function. By contrast, life events were comparable in patients and controls, and bore no association with symptoms. In this treated cohort, there was a trajectory of improvement in stress tolerance, symptoms and function over time. CONCLUSIONS Impaired stress tolerance was associated with a wide range of 'prodromal' symptoms, consistent with it being a core feature of the psychosis risk state. Self-reported life events were not relevant as a correlate of clinical status. As in other treated CHR cohorts, most patients improved over time across symptom domains.

Abstract
OBJECTIVE The use of psychotropic medications in Alzheimer's disease (AD) has been associated with both deleterious and potentially beneficial outcomes. We examined the longitudinal association of psychotropic medication use with cognitive, functional, and neuropsychiatric symptom (NPS) trajectories among community-ascertained incident AD cases from the Cache County Dementia Progression Study. METHODS A total of 230 participants were followed for a mean of 3.7 years. Persistency index (PI) was calculated for all antidepressants, selective serotonin reuptake inhibitors (SSRIs), antipsychotics (atypical and typical), and benzodiazepines as the proportion of observed time of medication exposure. Mixed-effects models were used to examine the association between PI for each medication class and Mini-Mental State Exam (MMSE), Clinical Dementia Rating Sum of Boxes (CDR-Sum), and Neuropsychiatric Inventory - Total (NPI-Total) trajectories, controlling for appropriate demographic and clinical covariates. RESULTS At baseline, psychotropic medication use was associated with greater severity of dementia and poorer medical status. Higher PI for all medication classes was associated with a more rapid decline in MMSE. For antidepressant, SSRI, benzodiazepine, and typical antipsychotic use, a higher PI was associated with a more rapid increase in CDR-Sum. For SSRIs, antipsychotics, and typical antipsychotics, a higher PI was associated with more rapid increase in NPI-Total. CONCLUSIONS Psychotropic medication use was associated with more rapid cognitive and functional decline in AD, and not with improved NPS. Clinicians may tend to prescribe psychotropic medications to AD patients at risk of poorer outcomes, but one cannot rule out the possibility of poorer outcomes being caused by psychotropic medications.

Abstract
BACKGROUND Stress sensitivity and HPA axis activity may be relevant to the development and expression of psychotic disorders. Cortisol secretion has been associated with positive symptoms both in patients with psychotic disorders and in young people at clinical risk for psychosis. Herein, we aimed to replicate these findings, to determine which positive symptoms may be associated with cortisol levels, and to explore any associations with affective symptoms and impaired stress tolerance. METHODS Thirty-one clinical high risk patients were evaluated in cross-section for associations between salivary cortisol levels upon clinic entry at 11 am, demographic variables, and clinical symptoms. RESULTS Salivary cortisol levels were unrelated to medication exposure or demographics, except for higher levels in the ten females studied. Salivary cortisol bore no relationship to overall positive symptom severity but was associated with anxiety, as well as with suspiciousness and impaired stress tolerance, which were themselves highly intercorrelated. CONCLUSIONS Cortisol secretion in the context of a putative novel social situation (i.e. clinic entry) may be a biological correlate of suspiciousness, impaired stress tolerance and affective symptoms in individuals vulnerable to developing psychosis. These associations are consistent with findings from experience sampling studies in individuals at risk for psychosis as well as basic studies of animal models of schizophrenia.

Abstract
OBJECTIVE To examine associations between frequency of ready-to-eat-cereal (RTEC) consumption and cognitive function among elderly men and women of the Cache County Study on Memory Health and Aging in Utah. DESIGN A population-based prospective cohort study established in Cache County, Utah in 1995. SETTING AND PARTICIPANTS 3831 men and women > 65 years of age who were living in Cache County, Utah in 1995. MEASUREMENT Diet was assessed using a 142-item food frequency questionnaire at baseline. Cognitive function was assessed using an adapted version of the Modified Mini-Mental State examination (3MS) at baseline and three subsequent interviews over 11 years. RTEC consumption was defined as daily, weekly, or infrequent use. RESULTS In multivariable models, more frequent RTEC consumption was not associated with a cognitive benefit. Those consuming RTEC weekly but less than daily scored higher on their baseline 3MS than did those consuming RTEC more or less frequently (91.7, 90.6, 90.6, respectively; p-value < 0.001). This association was maintained across 11 years of observation such that those consuming RTEC weekly but less than daily declined on average 3.96 points compared to an average 5.13 and 4.57 point decline for those consuming cereal more or less frequently (p-value = 0.0009). CONCLUSION Those consuming RTEC at least daily had poorer cognitive performance at baseline and over 11 years of follow-up compared to those who consumed cereal more or less frequently. RTEC is a nutrient dense food, but should not replace the consumption of other healthy foods in the diets' of elderly people. Associations between RTEC consumption, dietary patterns, and cognitive function deserve further study.

Abstract
The mother-infant dyad is crucial to early development in a variety of species. The complexity of social groupings in nonhuman primates makes this relationship resilient as well as susceptible to early challenges associated with environmental chaos. Quantitative behavior observations of bonnet monkey mother-infant interactions were collected from 28 mother-infant dyads between one and twelve months of age. Social groups were subjected to several prenatal and/or postnatal housing relocations within a single year resulting in two study groups. One group experienced relocations (ATYPICAL, n = 14) and the second group (TYPICAL, n = 14) was conceived and reared in the same location. Behaviors in the ethogram included mother-infant interactions and infant social interactions with other members of the group. Observations between ages of two to four months were analyzed by a mixed model analysis of variance including fixed effects of per and postnatal history (TYPICAL, ATYPICAL), age, and history by age interaction and random effects of mother and infant nested within mother. A significant effect of relocation history was noted on a number of infant behaviors. ATYPICAL infants were out of direct contact with their mother at an earlier age but remained in her proximity. Control of proximity shifted to offsrping in the ATYPICAL group compared to the TYPICAL group. Furthermore, greater social interactions between two and four months of age with other members of the social group as well as the ir mother were observed in the ATYPICAL group. It is suggested that continuous challenge associated with relocation may affect the infant at later developmental ages due to these early differences in ways that are yet unclear.

Abstract
UNLABELLED Schizophrenia has been linked with intrauterine exposure to maternal stress due to bereavement, famine and major disasters. Recent evidence suggests that human vulnerability may be greatest in the first trimester of gestation and rodent experiments suggest sex specificity. We aimed to describe the consequence of an acute maternal stress, through a follow-up of offspring whose mothers were pregnant during the Arab-Israeli war of 1967. A priori, we focused on gestational month and offspring's sex. METHOD In a pilot study linking birth records to Israel's Psychiatric Registry, we analyzed data from a cohort of 88,829 born in Jerusalem in 1964-76. Proportional hazards models were used to estimate the relative risk (RR) of schizophrenia, according to month of birth, gender and other variables, while controlling for father's age and other potential confounders. Other causes of hospitalized psychiatric morbidity (grouped together) were analyzed for comparison. RESULTS There was a raised incidence of schizophrenia for those who were in the second month of fetal life in June 1967 (RR = 2.3, 1.1-4.7), seen more in females (4.3, 1.7-10.7) than in males (1.2, 0.4-3.8). Results were not explained by secular or seasonal variations, altered birth weight or gestational age. For other conditions, RRs were increased in offspring who had been in the third month of fetal life in June 1967 (2.5, 1.2-5.2), also seen more in females (3.6, 1.3-9.7) than males (1.8, 0.6-5.2). CONCLUSION These findings add to a growing literature, in experimental animals and humans, attributing long term consequences for offspring of maternal gestational stress. They suggest both a sex-specificity and a relatively short gestational time-window for gestational effects on vulnerability to schizophrenia.

Abstract
BACKGROUND Vagus nerve stimulation (VNS) therapy is associated with a decrease in seizure frequency in partial-onset seizure patients. Initial trials suggest that it may be an effective treatment, with few side-effects, for intractable depression. METHOD An open, uncontrolled European multi-centre study (D03) of VNS therapy was conducted, in addition to stable pharmacotherapy, in 74 patients with treatment-resistant depression (TRD). Treatment remained unchanged for the first 3 months; in the subsequent 9 months, medications and VNS dosing parameters were altered as indicated clinically. RESULTS The baseline 28-item Hamilton Depression Rating Scale (HAMD-28) score averaged 34. After 3 months of VNS, response rates (> or = 50% reduction in baseline scores) reached 37% and remission rates (HAMD-28 score <10) 17%. Response rates increased to 53% after 1 year of VNS, and remission rates reached 33%. Response was defined as sustained if no relapse occurred during the first year of VNS after response onset; 44% of patients met these criteria. Median time to response was 9 months. Most frequent side-effects were voice alteration (63% at 3 months of stimulation) and coughing (23%). CONCLUSIONS VNS therapy was effective in reducing severity of depression; efficacy increased over time. Efficacy ratings were in the same range as those previously reported from a USA study using a similar protocol; at 12 months, reduction of symptom severity was significantly higher in the European sample. This might be explained by a small but significant difference in the baseline HAMD-28 score and the lower number of treatments in the current episode in the European study.

Abstract
BACKGROUND While there is considerable epidemiologic evidence that cardiovascular risk factors increase risk of incident Alzheimer disease (AD), few studies have examined their effect on progression after an established AD diagnosis. OBJECTIVE To examine the effect of vascular factors, and potential age modification, on rate of progression in a longitudinal study of incident dementia. METHODS A total of 135 individuals with incident AD, identified in a population-based sample of elderly persons in Cache County, UT, were followed with in-home visits for a mean of 3.0 years (range: 0.8 to 9.5) and 2.1 follow-up visits (range: 1 to 5). The Clinical Dementia Rating (CDR) Scale and Mini-Mental State Examination (MMSE) were administered at each visit. Baseline vascular factors were determined by interview and physical examination. Generalized least-squares random-effects regression was performed with CDR Sum of Boxes (CDR-Sum) or MMSE as the outcome, and vascular index or individual vascular factors as independent variables. RESULTS Atrial fibrillation, systolic hypertension, and angina were associated with more rapid decline on both the CDR-Sum and MMSE, while history of coronary artery bypass graft surgery, diabetes, and antihypertensive medications were associated with a slower rate of decline. There was an age interaction such that systolic hypertension, angina, and myocardial infarction were associated with greater decline with increasing baseline age. CONCLUSION Atrial fibrillation, hypertension, and angina were associated with a greater rate of decline and may represent modifiable risk factors for secondary prevention in Alzheimer disease. The attenuated decline for diabetes and coronary artery bypass graft surgery may be due to selective survival. Some of these effects appear to vary with age.

We assessed visual form perception using the Rorschach Comprehensive System (RCS) in 23 individuals at clinical high risk for psychosis, 15 individuals with recent onset schizophrenia (< or =2 years since onset), and 34 with chronic schizophrenia (> or =3 years since onset). All three groups demonstrated reduced conventional form perception (X+%), as compared with published norms, but did not differ significantly from one another. In contrast, the high-risk group had significantly better performance on an index of clarity of conceptual thinking (WSUM6) compared to the chronic schizophrenia patients, with the recent onset group scoring intermediate to the high-risk and chronic schizophrenia groups. The results suggest that individuals at clinical high risk for psychosis display substantial deficits in visual form perception prior to the onset of psychosis and that these deficits are comparable in severity to those observed in individuals with schizophrenia. Therefore, visual form perception deficits may constitute a trait-like risk factor for psychosis in high-risk individuals and may potentially serve as an endophenotype of risk for development of psychosis. Clarity of conceptual thinking was relatively preserved among high-risk patients, consistent with a relationship to disease expression, not risk. These deficits are discussed in the context of the putative neurobiological underpinnings of visual deficits and the developmental pathophysiology of psychosis in schizophrenia.

Abstract
BACKGROUND Epidemiologic studies have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may be useful for the prevention of Alzheimer disease (AD). By contrast, clinical trials have not supported NSAID use to delay or treat AD. Few studies have evaluated cognitive trajectories of NSAID users over time. METHODS Residents of Cache County, UT, aged 65 or older on January 1, 1995, were invited to participate in the study. At baseline, participants provided a detailed inventory of their medications and completed a revised Modified Mini-Mental State Examination (3MS). Participants (n = 3,383) who were cognitively normal at baseline were re-examined after 3 and 8 years. The association between NSAID use and 3MS scores over time was estimated using random effects modeling. RESULTS Associations depended upon when NSAIDs were started and APOE genotype. In participants who started NSAID use prior to age 65, those with no APOE epsilon4 alleles performed similarly to nonusers (a difference of 0.10 points per year; p = 0.19), while those with one or more epsilon4 allele(s) showed more protection (0.40 points per year; p = 0.0005). Among participants who first used NSAIDs at or after age 65, those with one or more epsilon4 alleles had higher baseline scores (0.95 points; p = 0.03) but did not show subsequent difference in change in score over time (0.06 points per year; p = 0.56). Those without an epsilon4 allele who started NSAID use after age 65 showed greater decline than nonusers (-0.16 points per year; p = 0.02). CONCLUSIONS Nonsteroidal anti-inflammatory drug use may help to prevent cognitive decline in older adults if started in midlife rather than late life. This effect may be more notable in those who have one or more APOE epsilon4 alleles.

Abstract
OBJECTIVE To investigate the probability of individual neuropsychiatric symptoms in dementia patients as a function of eight risk factors. METHODS In the Cache County Study, we administered the Neuropsychiatric Inventory (NPI) to 328 dementia patients at baseline. Approximately 18 months later, we re-administered the NPI to 184 participants available for follow-up. Generalized estimating equation methods were used to model the probability of individual neuropsychiatric symptoms as a function of: gender, age, education, dementia type and severity, APOE status, time of observation, and general medical health. RESULTS Women showed increased tendency toward anxiety, [odds ratio (OR) 2.22, 95% confidence interval (CI) 1.31-3.76] and delusions (OR 2.15, CI 1.22-3.78), but older persons of both sexes showed less tendency toward anxiety. Dementia severity increased the tendency toward hallucinations and agitation (OR 2.42, CI 1.81-3.23) and decreased risk of depression. Positive APOE epsilon4 status increased the tendency toward aberrant motor behavior (OR 1.84, CI 1.05-3.22). Among dementia diagnoses, those with Alzheimer's disease showed decreased tendency toward agitation (OR 0.58, CI 0.35-0.95), depression (OR 0.56, CI 0.33-0.96) and disinhibition (OR 0.46, CI 0.24-0.88). Later time of observation increased risk of aberrant motor behavior and delusions, and more serious medical comorbidity increased risk of, agitation, irritability, disinhibition, and aberrant motor behavior. CONCLUSIONS Gender, age, dementia severity, APOE epsilon4, dementia diagnosis, time of observation, and general medical health appear to influence the occurrence of individual neuropsychiatric symptoms.

Abstract
OBJECTIVE To examine 3-year rates of conversion to dementia, and risk factors for such conversion, in a population-based sample with diverse types of cognitive impairment. METHODS All elderly (aged 65 or older) residents of Cache County, UT, were invited to undergo two waves of dementia screening and assessment. Three-year follow-up data were available for 120 participants who had some form of mild cognitive impairment at baseline. Of these, 51 had been classified at baseline with prodromal Alzheimer disease (proAD), and 69 with other cognitive syndromes (CS). RESULTS Three-year rates of conversion to dementia were 46% among those with cognitive impairment at baseline. By comparison, 3.3% without impairment converted to dementia in the interval. Among converters, AD was the most common type of dementia. In individuals with at least one APOE epsilon4 allele, those with proAD or CS exhibited a 22- to 25-fold higher risk of dementia than cognitively unimpaired individuals (vs 5- to 10-fold higher risk in those without epsilon4). CONCLUSIONS Individuals with all types of mild cognitive impairment have an elevated risk of dementia over 3 years, more so in those with an APOE epsilon4 allele. These results suggest value in dementia surveillance for broad groups of cognitively impaired individuals beyond any specific category, and utility of APOE genotyping as a prognostic method.

Abstract
OBJECTIVE To examine the relative risk and population attributable risk (PAR) of death with dementia of varying type and severity and other risk factors in a population of exceptional longevity. METHODS Deaths were monitored over 5 years using vital statistics records and newspaper obituaries in 355 individuals with prevalent dementia and 4,328 without in Cache County, UT. Mean age was 83.3 (SD 7.0) years with dementia and 73.7 (SD 6.8) years without. History of coronary artery disease, hypertension, diabetes, and other life-shortening illness was ascertained from interviews. RESULTS Death certificates implicated dementia as an important cause of death, but other data suggested a stronger association. Adjusted Cox relative hazard and PAR of death were higher with dementia than with any other illness studied. Relative hazard of death with dementia was highest at ages 65 to 74, but the high prevalence of dementia after age 85 resulted in 27% PAR among the oldest old. Mortality increased substantially with severity of dementia. Alzheimer disease shortened survival time most dramatically in younger participants, but vascular dementia posed a greater mortality risk among the oldest old. CONCLUSION In this population, dementia was the strongest predictor of mortality, with a risk two to three times those of other life-shortening illnesses.

Abstract
We report on three males with prominent apathy as part of the symptom complex of depression or organic brain disease. Significant clinical responses were observed following treatment with bupropion, an antidepressant with dopamine (DA) reuptake activity. We present clinical evidence in support of the hypothesis that remission in these patients occurred as a consequence of bupropion-induced increases in central DA neurotransmission.

Abstract
BACKGROUND The role of allelic variation in APOE, the genetic locus for apolipoprotein E, in geriatric depression is poorly understood. There are conflicting reports as to an association between the epsilon4 allele and depression in late life. METHOD Using a community based study of non-demented elders in Cache County, Utah, that included many very old individuals, we examined the relationship between APOE and late-onset (age > 60) depression, with particular attention to possible age effects. RESULTS There was no overall association between APOE and depression. However, there was a significant interaction effect of APOE and age such that the relationship of late-onset depression with respect to presence of the epsilon4 allele was larger among those 80 and older compared with those below age 80. Consistent with previous studies, women were more likely to experience late-onset depression than men. CONCLUSIONS Because we excluded prevalent cases of dementia, this pattern of relative risk with age may reflect the appearance of depressive symptoms as a prodrome of Alzheimer's disease or vascular dementia. Longitudinal studies should help to confirm or refute this explanation of the data.

Abstract
Cellular immune responses play a critical role in the control of human immunodeficiency virus type 1 (HIV-1); however, the breadth of these responses at the single-epitope level has not been comprehensively assessed. We therefore screened peripheral blood mononuclear cells (PBMC) from 57 individuals at different stages of HIV-1 infection for virus-specific T-cell responses using a matrix of 504 overlapping peptides spanning all expressed HIV-1 proteins in a gamma interferon-enzyme-linked immunospot (Elispot) assay. HIV-1-specific T-cell responses were detectable in all study subjects, with a median of 14 individual epitopic regions targeted per person (range, 2 to 42), and all 14 HIV-1 protein subunits were recognized. HIV-1 p24-Gag and Nef contained the highest epitope density and were also the most frequently recognized HIV-1 proteins. The total magnitude of the HIV-1-specific response ranged from 280 to 25,860 spot-forming cells (SFC)/10(6) PBMC (median, 4,245) among all study participants. However, the number of epitopic regions targeted, the protein subunits recognized, and the total magnitude of HIV-1-specific responses varied significantly among the tested individuals, with the strongest and broadest responses detectable in individuals with untreated chronic HIV-1 infection. Neither the breadth nor the magnitude of the total HIV-1-specific CD8+-T-cell responses correlated with plasma viral load. We conclude that a peptide matrix-based Elispot assay allows for rapid, sensitive, specific, and efficient assessment of cellular immune responses directed against the entire expressed HIV-1 genome. These data also suggest that the impact of T-cell responses on control of viral replication cannot be explained by the mere quantification of the magnitude and breadth of the CD8+-T-cell response, even if a comprehensive pan-genome screening approach is applied.

Abstract
Logistic regression analyses are often challenged by the inability of unconditional likelihood-based approximations to yield consistent, valid estimates and p-values for model parameters. This can be due to sparseness or separability in the data. Conditional logistic regression, though useful in such situations, can also be computationally unfeasible when the sample size or number of explanatory covariates is large. We review recent developments that allow efficient approximate conditional inference, including Monte Carlo sampling and saddlepoint approximations. We demonstrate through real examples that these methods enable the analysis of significantly larger and more complex data sets. We find in this investigation that for these moderately large data sets Monte Carlo seems a better alternative, as it provides unbiased estimates of the exact results and can be executed in less CPU time than can the single saddlepoint approximation. Moreover, the double saddlepoint approximation, while computationally the easiest to obtain, offers little practical advantage. It produces unreliable results and cannot be computed when a maximum likelihood solution does not exist.

Abstract
The problem of testing a dose-response relationship in the presence of exchangeably correlated binary data has been addressed using a variety of models. Most commonly used approaches are derived from likelihood or generalized estimating equations and rely on large-sample theory to justify their inferences. However, while earlier work has determined that these methods may perform poorly for small or sparse samples, there are few alternatives available to those faced with such data. We propose an exact trend test for exchangeably correlated binary data when groups of correlated observations are ordered. This exact approach is based on an exponential model derived by Molenberghs and Ryan (1999) and Ryan and Molenberghs (1999) and provides natural analogues to Fisher's exact test and the binomial trend test when the data are correlated. We use a graphical method with which one can efficiently compute the exact tail distribution and apply the test to two examples.

Abstract
Although prior studies suggest reduced androgen levels in women with acquired immune deficiency syndrome wasting, little is known regarding the regulation of adrenal and ovarian androgen secretion in such patients. We investigated ovarian and adrenal function in 13 human immunodeficiency virus-infected women with acquired immune deficiency syndrome wasting and 21 age- and body mass index-matched healthy control subjects studied in the early follicular phase. Subjects received hCG (5000 U, im) on d 1 and Cosyntropin (0.25 mg, i.v.) on d 3 after dexamethasone (1 mg, orally, at 2400 h) pretreatment on d 2. At baseline, human immunodeficiency virus-infected subjects demonstrated significantly reduced T [18 +/- 2 vs. 25 +/- 2 ng/dl (0.6 +/- 0.1 vs. 0.9 +/- 0.1 nmol/liter); P = 0.02], free T [1.5 +/- 0.1 vs. 2.4 +/- 0.2 pg/ml (5.3 +/- 0.5 vs. 8.3 +/- 0.6 pmol/liter); P = 0.001], androstenedione [119 +/- 6 vs. 162 +/- 14 ng/dl (4.16 +/- 0.20 vs. 5.66 +/- 0.48 nmol/liter); P = 0.02], and dehydroepiandrosterone sulfate [0.96 +/- 0.17 vs. 1.55 +/- 0.19 microg/ml (2.6 +/- 0.5 vs. 4.2 +/- 0.5 micromol/liter); P = 0.047] levels compared with the control subjects. T [8 +/- 2 vs. 6 +/- 2 ng/dl (0.3 +/- 0.1 vs. 0.2 +/- 0.1 nmol/liter); P = 0.48], free T [0.5 +/- 0.2 vs. 0.4 +/- 0.1 pg/ml (1.7 +/- 0.7 vs. 1.5 +/- 0.5 pmol/liter); P = 0.85], 17 hydroxyprogesterone [0.5 +/- 0.2 vs. 0.7 +/- 0.2 microg/liter (1.6 +/- 0.6 vs. 2.0 +/- 0.6 nmol/liter); P = 0.63], and androstenedione [-1 +/- 12 vs. 8 +/- 11 ng/dl (-0.03 +/- 0.42 vs. 0.28 +/- 0.39 nmol/liter), P = 0.61] responses to hCG were not different between the groups. Cortisol responses were increased and dehydroepiandrosterone sulfate responses were decreased in the human immunodeficiency virus-infected vs. control subjects after ACTH stimulation. The ratio of DHEA to cortisol was significantly decreased at 60 (71 +/- 11 vs. 107 +/- 10; P = 0.02) and 90 (63 +/- 8 vs. 102 +/- 9; P = 0.004) min post-ACTH in the human immunodeficiency virus-infected patients compared with control subjects. Baseline urinary free cortisol levels were not different between the groups [36 +/- 9 vs. 36 +/- 5 microg/24 h (99 +/- 26 vs. 100 +/- 13 nmol/d)]. The DHEA to cortisol ratio correlated with the CD4 count (r = 0.67; P = 0.01). These data demonstrate significant shunting of adrenal steroid metabolism away from androgenic pathways and toward cortisol production in human immunodeficiency virus-infected women with the wasting syndrome. In contrast, our data suggest intact ovarian androgen responsivity to hCG stimulation. Further studies of the mechanism of adrenal steroid shunting and the efficacy of androgen replacement in human immunodeficiency virus-infected women are necessary.

Abstract
BACKGROUND Cognitive deficits are a major determinant of social and occupational dysfunction in schizophrenia. In this study, we determined whether neurocognitive enhancement therapy (NET) in combination with work therapy (WT) would improve performance on neuropsychological tests related to but different from the training tasks. METHODS Sixty-five patients with schizophrenia or schizoaffective disorder were randomly assigned to NET plus WT or WT alone. Neurocognitive enhancement therapy included computer-based training on attention, memory, and executive function tasks; an information processing group; and feedback on cognitive performance in the workplace. Work therapy included paid work activity in job placements at the medical center (eg, mail room, grounds, library) with accompanying supports. Neuropsychological testing was performed at intake and 5 months later. RESULTS Prior to enrollment, both groups did poorly on neuropsychological testing. Patients receiving NET + WT showed greater improvements on pretest-posttest variables of executive function, working memory, and affect recognition. As many as 60% in the NET + WT group improved on some measures and were 4 to 5 times more likely to show large effect-size improvements. The number of patients with normal working memory performance increased significantly with NET + WT, from 45% to 77%, compared with a decrease from 56% to 45% for those receiving WT. CONCLUSIONS Computer training for cognitive dysfunction in patients with schizophrenia can have benefits that generalize to independent outcome measures. Efficacy may result from a synergy between NET, which encourages mental activity, and WT, which allows a natural context for mental activity to be exercised, generalized, and reinforced.

Abstract
Loss of lean body and muscle mass characterizes the acquired immunodeficiency syndrome (AIDS) wasting syndrome (AWS). Testosterone and exercise increase muscle mass in men with AWS, with unclear effects on muscle composition. We examined muscle composition in 54 eugonadal men with AWS who were randomized to 1) testosterone (200 mg im weekly) or placebo and simultaneously to 2) resistance training or no training in a 2 × 2 factorial design. At baseline and after 12 wk, we performed assessments of whole body composition by dual-energy X-ray absorptiometry and single-slice computed tomography for midthigh cross-sectional area and muscle composition. Leaner muscle has greater attenuation. Baseline muscle attenuation correlated inversely with whole body fat mass ( r = −0.52, P = 0.0001). This relationship persisted in a model including age, body mass index, testosterone level, viral load, lean body mass, and thigh muscle cross-sectional area ( P = 0.02). Testosterone ( P = 0.03) and training ( P = 0.03) increased muscle attenuation. These data demonstrate that thigh muscle attenuation by computed tomography varies inversely with whole body fat and increases with testosterone and training. Anabolic therapy in these patients increases muscle leanness.

Abstract
Human immunodeficiency virus (HIV) lipodystrophy (LIPO) is characterized by increased visceral adiposity, peripheral fat atrophy, dyslipidemia, and insulin resistance. GH concentrations are known to vary inversely with excess weight and body fat but have not been investigated in HIV lipodystrophy. Twenty-one subjects with HIV LIPO, 20 HIV-infected nonlipodystrophy subjects (NONLIPO), and 20 control (C) subjects were prospectively recruited for this study and compared. Subjects in the three groups were all male, age-matched [median, 47 yr old (interquartile range, 37-50) LIPO; 41 (37-44) NONLIPO; and 43 (37-49) C], and body mass index-matched [median, 24.3 kg/m(2) (interquartile range, 22.2-26.6) LIPO; 24.4 (23.3-25.9) NONLIPO; and 24.8 (22.7-26.1) C] (P: > 0.05 for all comparisons). Visceral abdominal fat [16,124 mm(2) (11,246-19,790) LIPO; 7,559 (5,134-11,201) NONLIPO; and 8,803 (6,165-11,623) C; P < 0.01 LIPO vs. NONLIPO and LIPO vs. C] and the ratio of visceral abdominal fat to sc abdominal fat [1.37 (0.71-2.44) LIPO vs. 0.57 (0.47-0.78) NONLIPO vs. 0.55 (0.41-0.71) C, P < 0.01 LIPO vs. NONLIPO and LIPO vs. C] were significantly increased in the LIPO subjects but were not significantly different between NONLIPO and C. The mean overnight GH concentration, determined from frequent sampling every 20 min (from 2000 h to 0800 h) was decreased in the LIPO subjects [0.38 microg/L (0.13-0.67) LIPO vs. 0.96 (0.53-1.30) NONLIPO vs. 0.81 (0.49-1.03) C, P < 0.05 LIPO vs. NONLIPO and LIPO vs. C] and not significantly different between NONLIPO and C. Pulse analysis demonstrated decreased baseline GH [0.08 microg/L (0.06-0.21) LIPO vs. 0.19 (0.10-0.32) NONLIPO vs. 0.17 (0.12-0.57) C, P < 0.05 LIPO vs. NONLIPO and LIPO vs. C] and GH peak amplitude [1.06 microg/L (0.46-1.94) LIPO vs. 2.47 (1.22-3.43) NONLIPO and 2.27 (1.36-4.25) C, P < 0.05 LIPO vs. NONLIPO and LIPO vs. C] in the LIPO subjects but no significant difference in pulse frequency. No significant differences were observed between NONLIPO and C for any GH parameter. Insulin-like growth factor-I was not different between the groups. Total body fat (r = -0.40, P = 0.01) and visceral fat (r = -0.58, P = 0.0001) correlated inversely with mean overnight GH concentrations in the HIV-infected patients. In a multivariate regression model, controlling for age, body mass index, body fat, and visceral fat, only visceral fat was a significant predictor of mean GH concentrations (P = 0.0036, r(2) for model = 0.40). These data demonstrate normal GH pulse frequency and insulin-like growth factor-I concentrations but reduced mean GH concentrations, basal GH concentrations, and GH pulse amplitude in patients with HIV lipodystrophy. Increased visceral adiposity is the strongest predictor of reduced GH concentrations in HIV lipodystrophy. Further studies are necessary to determine the clinical significance of reduced GH in patients with HIV lipodystrophy.

Abstract
This review explores the neurobiology of stress and its possible role in the etiology of schizophrenia. Major life events may play a role in onset and relapse in schizophrenia. Other data suggest that early stress exposure increases schizophrenia risk, especially in individuals with latent vulnerability. Animal research has led to an elucidation of the mechanisms by which stress and cortisol are toxic to the hippocampus and impair cognition. Associations among these factors have been found in a variety of human conditions, including psychiatric illness and normal aging. These mechanisms are plausible in schizophrenia, which is characterized by a degree of cortisol dysregulation, hippocampal abnormality, and cognitive impairment. Characterization of the role of the stress cascade in schizophrenia has implications for novel pharmacologic and other treatment, especially for cognitive symptoms, which are debilitating and largely refractory to treatment.

Abstract
We evaluated metabolic and clinical features of 71 HIV-infected patients with lipodystrophy by comparing them with 213 healthy control subjects, matched for age and body mass index, from the Framingham Offspring Study. Thirty HIV-infected patients without fat redistribution were compared separately with 90 matched control subjects from the Framingham Offspring Study. Fasting glucose, insulin, and lipid levels; glucose and insulin response to standard oral glucose challenge; and anthropometric measurements were determined. HIV-infected patients with lipodystrophy demonstrated significantly increased waist-to-hip ratios, fasting insulin levels, and diastolic blood pressure compared with controls. Patients with lipodystrophy were more likely to have impaired glucose tolerance, diabetes, hypertriglyceridemia, and reduced levels of high-density lipoprotein (HDL) cholesterol than were controls. With the exception of HDL cholesterol level, these risk factors for cardiovascular disease (CVD) were markedly attenuated in patients without lipodystrophy and were not significantly different in comparison with controls. These data demonstrate a metabolic syndrome characterized by profound insulin resistance and hyperlipidemia. CVD risk factors are markedly elevated in HIV-infected patients with fat redistribution.

Abstract
The Cochran-Armitage test for trend is a popular statistical procedure for detecting increasing or decreasing probabilities of response when a categorical exposure is ordered. Such associations may arise in a variety of biomedical research settings, particularly in dose-response designs such as carcinogenicity experiments. Previously, computing limitations mandated the use of the asymptotic trend test, but with the availability of new algorithms, increased computing power, and appropriate software the exact trend test is now a practical option. Nevertheless, the exact test is sometimes criticized on the grounds that it is conservative. In this paper we investigate the implications of this conservatism by comparing the true type I error and power of three alternative tests of trend - the asymptotic test, the exact test and an admissible exact test proposed by Cohen and Sackrowitz. The computations are performed by an extension to the network algorithm of Mehta et al. This allows us to make precise power comparisons between the tests under any given design without resorting to simulation. We show how this tool can guide investigators in choosing the most appropriate test by considering the design of two-year carcinogenicity studies carried out by the National Toxicology Program. We additionally compare the tests for various other combinations of sample sizes and number of groups or levels of exposure. We conclude that the asymptotic test, while more powerful where it is valid, generally does not preserve the type I error. This violation of the a priori testing level can be greatly affected by imbalance in the data or unequal spacing of dose levels.

Abstract
Previous studies have indicated that there is a significant prevalence (50%) of hypogonadism among men with acquired immunodeficiency syndrome (AIDS)-associated wasting, and for these patients testosterone administration has been shown to increase lean body mass and improve quality of life. However, the prevalence of hypogonadism is not known among men with weight loss related to human immunodeficiency virus (HIV) infection who are receiving highly active antiretroviral therapy (HAART). From 1997 through 1999, we investigated total and free testosterone levels in 90 men who were <90% of ideal body weight or had weight loss of >10% from preillness weight; 71% of these subjects were receiving HAART. Twenty-one percent of the subjects receiving HAART had low free testosterone levels. No correlation was seen between weight, CD4 cell count, medication status, and other clinical factors. These data suggest that hypogonadism remains relatively common in men with AIDS wasting, despite treatment with HAART. HIV-infected men with wasting syndrome should be screened for hypogonadism and receive physiological androgen replacement therapy if they are hypogonadal.

Abstract
BACKGROUND Lean body mass is an important predictor of survival and functional status in patients with AIDS wasting. The bias between different techniques for assessing body composition in AIDS wasting is not known. DESIGN We compared total body potassium (TBK) with fat-free mass (FFM) determined by dual-energy X-ray absorptiometry (DXA), bioelectrical impedance analysis (BIA), and skinfold-thickness measurement (SKF) in 132 patients (63 men, 69 women) with AIDS wasting (weight < 90% of ideal body weight, or weight loss > 10% of original, or both). None of the subjects exhibited clinical lipodystrophy. Comparisons were made by using different BIA equations. RESULTS Lean body mass determined by DXA was highly correlated with TBK in men (r = 0.79, P: < 0.0001) and women (r = 0.84, P: < 0.0001). FFM(BIA) and FFM(DXA) were significantly different (P: < 0.01 in men and P: < 0.0001 in women). The difference between FFM(DXA) and FFM(BIA) was significantly greater with greater weight and body fat, particularly in HIV-infected women (r = -0.39, P: = 0.001 for weight; r = -0.60, P: < 0.0001 for fat). The comparability of FFM and fat mass determined by DXA and BIA was dependent on the specific BIA equation used. Among men, no single BIA equation was more highly predictive of fat mass and FFM in comparison with DXA. CONCLUSIONS The differences between DXA, BIA, and SKF in the determination of fat mass and FFM are significant in patients with AIDS wasting. BIA overestimates FFM compared with DXA in those with greater body fat. Standard BIA equations may not accurately estimate FFM and fat mass in men and women with AIDS wasting.

Abstract
A novel lipodystrophy syndrome characterized by insulin resistance, hypertriglyceridemia, and fat redistribution has recently been described in human immunodeficiency virus (HIV)-infected men and women. Women with the HIV lipodystrophy syndrome exhibit a marked increase in waist-to-hip ratio and truncal adiposity; however, it is unknown whether androgen levels are increased in these patients. In this study, we assessed androgen levels in female patients with clinical lipodystrophy based on evidence of significant fat redistribution in the trunk, extremities, neck and/or face (LIPO: n = 9; age, 35.7+/-1.7 yr; BMI, 24.7+/-0.8 kg/m2) in comparison with age- and BMI-matched nonlipodystrophic HIV-infected females (NONLIPO: n = 14; age, 37.6+/-1.1 yr; BMI, 23.4+/-0.6 kg/m2) and healthy non-HIV-infected control subjects (C: n = 16; age, 35.8+/-0.9 yr; BMI, 23.1+/-0.4 kg/m2). Fasting insulin, lipid levels, virologic parameters, and regional body composition using dual energy x-ray absorptiometry were also assessed. Total testosterone [ LIPO, 33+/-6 ng/dL (1.1+/-0.2 nmol/L); NONLIPO, 17+/-2 ng/dL (0.6+/-0.1 nmol/L); C, 23+/-2 ng/dL (0.8+/-0.1 nmol/L); P < 0.05 LIPO vs. C and LIPO vs. NONLIPO] and free testosterone determined by equilibrium dialysis [LIPO, 4.5+/-0.9 pg/mL (16+/-3 pmol/L); NONLIPO, 1.7+/-0.2 pg/mL (6+/-1 pmol/L); C, 2.4+/-0.2 pg/mL (8+/-1 pmol/L); P < 0.05 LIPO vs. C and LIPO vs. NONLIPO] were increased in the lipodystrophic patients. Sex hormone-binding globulin levels were not significantly different between LIPO and C, but were significantly lower in the LIPO vs. NONLIPO patients (LIPO 84+/-7 vs. NONLIPO 149+/-17 nmol/L, P < 0.05). The LH/FSH ratio was significantly increased in the LIPO group compared with the NONLIPO and C subjects (LIPO, 2.0+/-0.6; NONLIPO, 1.1+/-0.1; C, 0.8+/-0.1; P < 0.05 LIPO vs. NONLIPO and LIPO vs. C). Body fat distribution was significantly different between LIPO and C subjects. Trunk to extremity fat ratio (1.46+/-0.17 vs. 0.75+/-0.05, LIPO vs. C, P < 0.05) was increased and extremity to total fat ratio decreased (0.40+/-0.03 vs. 0.55+/-0.01, LIPO vs. C, P < 0.05). In contrast, fat distribution was not different in the NONLIPO group vs. control subjects. Among the HIV-infected patients, free testosterone correlated with percent truncal fat (trunk fat/trunk mass) (r = 0.43, P = 0.04). These data suggest that hyperandrogenemia is another potentially important feature of the HIV-lipodystrophy syndrome in women. Additional studies are necessary to determine the clinical significance of increased androgen levels and the relationship of hyperandrogenism to fat redistribution and insulin resistance in this population of patients.

Abstract
BACKGROUND Substantial loss of muscle mass occurs among men with AIDS wasting. OBJECTIVE To investigate the independent effects of testosterone therapy and progressive resistance training in eugonadal men with AIDS wasting. DESIGN Randomized, controlled trial. SETTING University hospital. PATIENTS 54 eugonadal men with AIDS wasting (weight < 90% ideal body weight or weight loss > 10%). INTERVENTION In a 2 x 2 factorial design, patients were assigned to receive testosterone enanthate (200 mg/wk) or placebo injections and progressive resistance training (three times weekly) or no training for 12 weeks. MEASUREMENTS Cross-sectional muscle area and other indices of muscle mass. RESULTS Cross-sectional muscle area increased in response to training compared with nontraining (change in arm muscle mass, 499 +/- 349 mm2 vs. 206 +/- 264 mm2 [P = 0.004]; change in leg muscle mass, 1106 +/- 854 mm2 vs. 523 +/- 872 mm2 [P = 0.045]) and in response to testosterone therapy compared with placebo (change in arm muscle mass, 512 +/- 371 mm2 vs. 194 +/- 215 mm2 [P< 0.001]; change in leg muscle mass, 1,236 +/- 881 mm2 vs. 399 +/- 729 mm2 [P = 0.002]). Levels of high-density lipoprotein cholesterol decreased in response to testosterone therapy compared with placebo (-0.03 +/- 0.13 mmol/L vs. 0.05 +/- 0.13 mmol/L [-1 +/- 5 mg/dL vs. 2 +/- 5 mg/dL]; P= 0.011) and increased in response to training compared with nontraining (0.05 +/- 0.13 mmol/L vs. 0.00 +/- 0.16 mmol/L [2 +/- 5 mg/dL vs. 0 +/- 6 mg/dL]; P = 0.052). CONCLUSIONS In contrast to anabolic therapies that may have adverse effects on metabolic variables, supervised exercise effectively increases muscle mass and is associated with significant positive health benefits in eugonadal men with AIDS wasting.

Abstract
CONTEXT A syndrome of lipodystrophy, characterized by fat redistribution and insulin resistance, has been estimated to affect the majority of human immunodeficiency virus (HIV)-infected individuals who are treated with combination antiretroviral therapy. There are no proven therapies for the metabolic disturbances associated with HIV lipodystrophy syndrome. OBJECTIVE To determine the safety and efficacy of metformin therapy in HIV-infected patients with fat redistribution and abnormal glucose homeostasis. DESIGN AND SETTING Randomized, double-blind, placebo-controlled pilot study conducted in a university hospital between December 1998 and January 2000. PATIENTS Twenty-six HIV-infected, nondiabetic patients with fat redistribution and abnormal oral glucose tolerance test (OGTT) results, hyperinsulinemia, or both. INTERVENTIONS Patients were randomly assigned to receive metformin, 500 mg twice daily (n = 14), or identical placebo (n = 12), for 3 months. MAIN OUTCOME MEASURES Insulin area under the curve (AUC), calculated 120 minutes following a 75-g OGTT at baseline vs at 3-month follow-up and compared between treatment groups. RESULTS Patients treated with metformin demonstrated significant reductions in mean (SEM) insulin AUC 120 minutes after OGTT (-2930 [912] vs -414 [432] microIU/mL [-20349 6334 vs -2875 3000 pmol/L]; P =.01), weight (-1.3 [0.6] vs 1.1 [0.4] kg; P =.005), and diastolic blood pressure (-5 [4] vs 5 [2] mm Hg; P =.009) vs controls, respectively. Metformin therapy was associated with a decrease in visceral abdominal fat (VAT; -1115 [819] vs 1191 [699] mm(2); P =.08) and a proportional reduction in subcutaneous abdominal fat (SAT); the VAT-SAT ratio was unchanged in metformin-treated vs placebo-treated patients. No increase in lactate or liver transaminase levels was observed with metformin treatment. Mild diarrhea was the most common adverse effect of metformin. No patient discontinued therapy because of adverse effects. CONCLUSIONS This study suggests that a relatively low dosage of metformin reduces insulin resistance and related cardiovascular risk parameters in HIV-infected patients with lipodystrophy.

Abstract
Hypogonadism is prevalent among human immunodeficiency virus-infected men, in whom significantly reduced quality of life and mood disturbances have been reported. Previous studies have not investigated the relationship between depression score and gonadal function among such patients. We first compared depression scores in hypogonadal (n = 52) and eugonadal (n = 10) patients with acquired immunodeficiency syndrome (AIDS) wasting, matched for weight and disease status, and then investigated the effects of testosterone administration on depression score in a randomized, double-blind, placebo-controlled study among the group of hypogonadal men with AIDS wasting. The primary end point in all comparisons was the Beck Depression Inventory. Hypogonadal patients demonstrated significantly increased scores on the Beck inventory compared with eugonadal-, age-, weight-, and disease status-matched subjects (15.5+/-1.1 vs. 10.6+/-1.4 mean +/- SEM, P = 0.02). Among the combined hypogonadal and eugonadal subjects, a significant inverse correlation was seen between the Beck score and both free (r = 0.41, P<0.01) and total serum testosterone levels (r = -0.43, P<0.001). The relationship between the Beck score and testosterone levels remained highly significant, controlling for weight, viral load, CD4 count, and antidepressant use (P<0.01 for free testosterone, P<0.001 for total testosterone). Furthermore, when subjects were divided into two groups, based on a Beck score greater than 18 or less than or equal to 18, serum total and free testosterone levels were significantly lower in the subjects with a Beck score greater than 18, whereas there were no differences in weight, viral load, CD4 count, or Karnofsky status. End of study data were available in 39 patients who completed the randomized, placebo-controlled study. Beck score decreased significantly only in the subjects receiving testosterone (-5.8+/-1.3, P< 0.001), but not in subjects randomized to placebo (-2.7+/-1.3, P> 0.05). In a regression analysis, the change in Beck score was related significantly to change in weight (P<0.01). These data demonstrate increased depression score in association with hypogonadism in men with AIDS wasting, independent of weight, virologic status, and other disease factors. In such patients, administration of testosterone results in a significant improvement in depression inventory score. This effect may be a direct effect of testosterone or related to positive effects of testosterone on weight and/or other anthropometric indices. Additional studies are needed to assess the effects of testosterone on clinical depression indices in human immunodeficiency virus-infected patients.

Abstract
Fat redistribution in the setting of protease inhibitor use is increasingly common and is associated with insulin resistance in human immunodeficiency virus (HIV)-infected patients. However, little is known regarding the factors that may contribute to abnormal insulin regulation in this population. We assessed fasting insulin levels in HIV-infected men and determined the relationship among insulin, body composition, endogenous gonadal steroid concentrations, and antiviral therapy in this population. We also determined the effects of exogenous testosterone administration using the homeostatic model for insulin resistance (HOMA IR) in hypogonadal HIV-infected men with the acquired immunodeficiency syndrome wasting syndrome. Fifty HIV-infected men with acquired immunodeficiency syndrome wasting were compared with 20 age- and body mass index (BMI)-matched healthy control subjects. Insulin concentrations were significantly increased in HIV-infected patients compared to those in control patients (16.6+/-1.8 vs. 10.4+/-0.8 microU/mL; P<0.05) and were increased in nucleoside reverse transcriptase (NRTI)-treated patients who did not receive a protease inhibitor (PI; 21.7+/-4.3 vs. 10.4+/-0.8 microU/mL; P<0.05). Insulin concentrations and HOMA IR were inversely correlated with the serum free testosterone concentration (r = -0.36; P = 0.01 for insulin level; r = -0.30; P = 0.03 for HOMA), but not to body composition parameters, age, or BMI. In a multivariate regression analysis, free testosterone (P = 0.05), BMI (P<0.01), and lean body mass (P = 0.04) were significant. Lower lean body mass and higher BMI predicted increased insulin resistance. The HIV-infected patients demonstrated an increased trunk fat to total fat ratio (0.49+/-0.02 vs. 0.45+/-0.02; P<0.05) and an increased trunk fat to extremity fat ratio (1.27+/-0.09 vs. 0.95+/-0.06, P = 0.01), but a reduced extremity fat to total fat ratio (0.44+/-0.01 vs. 0.49 + 0.01; P = 0.02) and reduced overall total body fat (13.8+/-0.7 vs. 17.2+/-0.9 kg; P<0.01) compared to the control subjects. Increased truncal fat and reduced extremity fat were seen among NRTI-treated patients, but this pattern was most severe among patients receiving combined NRTI and PI therapy [trunk fat to extremity ratio, 1.47+/-0.15 vs. 0.95+/-0.06 (P<0.01); extremity fat to total fat ratio, 0.40+/-0.02 vs. 0.49+/-0.01 (P<0.05)]. Insulin responses to testosterone administration were investigated among 52 HIV-infected men with hypogonadism and wasting (weight <90% ideal body weight and/or weight loss >10%) randomized to either testosterone (300 mg, im, every 3 weeks) or placebo for 6 months. Testosterone administration reduced HOMA IR in the HIV-infected men (-0.6+/-0.7 vs. +1.41+/-0.8, testosterone vs. placebo, P = 0.05) in association with increased lean body mass (P = 0.02). These data demonstrate significant hyperinsulinemia in HIV-infected patients, which can occur in the absence of PI use. In NRTI-treated patients not receiving PI, a precursor phenotype is apparent, with increased truncal fat, reduced extremity fat, and increased insulin concentrations. This phenotype is exaggerated in patients receiving PI therapy, with further increased truncal fat and reduced extremity fat, although hyperinsulinemia per se is not worse. Endogenous gonadal steroid levels are inversely related to hyperinsulinemia in HIV-infected men, but reduced lean body mass and increased weight are the primary independent predictors of hyperinsulinemia. Indexes of insulin sensitivity improve in response to physiological androgen administration among hypogonadal HIV-infected patients, and this change is again related primarily to increased lean body mass in response to testosterone administration.

Abstract
A novel lipodystrophy syndrome (characterized by insulin resistance, hypertriglyceridemia, and fat redistribution) has recently been described in human immunodeficiency virus (HIV)-infected patients. However, investigation of the lipodystrophy syndrome has generally been limited to men; and a comprehensive evaluation of insulin, lipids, and regional body composition has not been performed in the expanding population of HIV-infected women. In this study, we assessed fasting insulin, lipid levels, virologic parameters, and regional body composition, using dual-energy x-ray absorptiometry, in a cohort of 75 HIV-infected women (age, 25-46 yr), in comparison with 30 healthy weight-matched premenopausal control subjects. HIV-infected women demonstrated significant truncal adiposity (38.5 +/- 0.9 vs. 34.9 +/- 1.3%, P < 0.05) hyperinsulinemia (15.9 +/- 1.5 vs. 7.5 +/- 0.6 microU/mL, P < 0.001) and an increased insulin-to-glucose ratio (0.2 +/- 0.02 vs. 0.1 +/- 0.03, P < 0.001), compared with control subjects. Insulin and the insulin-to-glucose ratio were increased, even among HIV-infected patients with low body weight (<90% of ideal body weight) (insulin, 13.3 +/- 2.8 microU/mL, P < 0.01 vs. control; insulin/glucose, 0.2 +/- 0.04, P < 0.01 vs. control). Insulin and the insulin-to-glucose ratio were most significantly elevated among patients with increased truncal adiposity (insulin, 28.2 +/- 3.2 microU/mL, P < 0.001 vs. control; insulin/ glucose, 0.32 +/- 0.04, P < 0.001 vs. control). In contrast, no differences in insulin were seen in relation to protease inhibitor (PI) use. Similarly, HIV-infected women also demonstrated significant hypertriglyceridemia (144 +/- 15 vs. 66 +/- 23 mg/dL, P < 0.01 vs. controls), which was present even among low-weight patients (148 +/- 32 mg/dL, P < 0.001 vs. control) but was not related to truncal adiposity or PI usage. These data demonstrate significant hyperinsulinemia and truncal adiposity in HIV-infected women. Our data suggest that these metabolic abnormalities occur at baseline in HIV-infected women, independent of PI use. However, these data do not rule out a direct effect of PI therapy on fat metabolism or indirect effects of PI therapy to further worsen glucose and lipid homeostasis in association with weight gain and disease recovery.

Abstract
Fifty-one human immunodeficiency virus-positive men with hypogonadism and wasting were randomized to receive testosterone enanthate, 300 mg i.m. every 3 weeks, or placebo for 6 months, followed by open-label testosterone administration for 6 months. Subjects initially randomized to placebo gained lean body mass (LBM) only after crossover to testosterone administration (mean change +/- standard error of the mean, -0.6 +/- 0.7 kg [months 0-6] vs. 1.9 +/- 0.7 kg [months 6-12]; P = .03). In contrast, subjects initially randomized to testosterone continued to gain LBM during open-label administration (2.0 +/- 0.7 kg [months 0-6] vs. 1.6 +/- 0.6 kg [months 6-12]; P = .62) and had gained more LBM at 1 year than did subjects receiving testosterone for only the final 6 months of the study (3.7 +/- 0.8 kg vs. 1.0 +/- 1.0 kg; P = .05). Testosterone administration results in sustained increases in LBM during 1 year of therapy in hypogonadal men with AIDS wasting.
