Consensus about the differing characteristics of men and women exists across groups differing in sex, age, marital status, and education. Masculine characteristics are positively valued more often than feminine characteristics. Positively‐valued masculine traits form a cluster entailing competence; positively‐valued feminine traits reflect warmth‐expressiveness. Sex‐role definitions are incorporated into the self‐concepts of both men and women; moreover, these sex‐role differences are considered desirable by college students and healthy by mental health professionals. Individual differences in sex related self‐concepts are related to sex‐role relevant behaviors such as achieved and ideal family size. Sex‐role perceptions also vary as a function of maternal employment.

UNLABELLED: BMD, bone microarchitecture, and bone mechanical properties assessed in vivo by finite element analysis were associated with wrist fracture in postmenopausal women. INTRODUCTION: Many fractures occur in individuals with normal BMD. Assessment of bone mechanical properties by finite element analysis (FEA) may improve identification of those at high risk for fracture. MATERIALS AND METHODS: We used HR-pQCT to assess volumetric bone density, microarchitecture, and microFE-derived bone mechanical properties at the radius in 33 postmenopausal women with a prior history of fragility wrist fracture and 33 age-matched controls from the OFELY cohort. Radius areal BMD (aBMD) was also measured by DXA. Associations between density, microarchitecture, mechanical parameters and fracture status were evaluated by univariate logistic regression analysis and expressed as ORs (with 95% CIs) per SD change. We also conducted a principal components (PCs) analysis (PCA) to reduce the number of parameters and study their association (OR) with wrist fracture. RESULTS: Areal and volumetric densities, cortical thickness, trabecular number, and mechanical parameters such as estimated failure load, stiffness, and the proportion of load carried by the trabecular bone at the distal and proximal sites were associated with wrist fracture (p < 0.05). The PCA revealed five independent components that jointly explained 86.2% of the total variability of bone characteristics. The first PC included FE-estimated failure load, areal and volumetric BMD, and cortical thickness, explaining 51% of the variance with an OR for wrist fracture = 2.49 (95% CI, 1.32-4.72). Remaining PCs did not include any density parameters. The second PC included trabecular architecture, explaining 12% of the variance, with an OR = 1.82 (95% CI, 0.94-3.52). The third PC included the proportion of the load carried by cortical versus trabecular bone, assessed by FEA, explaining 9% of the variance, and had an OR = 1.61 (95% CI, 0.94-2.77). Thus, the proportion of load carried by cortical versus trabecular bone seems to be associated with wrist fracture independently of BMD and microarchitecture (included in the first and second PC, respectively). CONCLUSIONS: These results suggest that bone mechanical properties assessed by microFE may provide information about skeletal fragility and fracture risk not assessed by BMD or architecture measurements alone and are therefore likely to enhance the prediction of wrist fracture risk.

Hyperuricaemia is common in subjects with cardiovascular disease, but is not commonly considered a true risk factor. Recent studies suggest that uric acid is biologically active and can stimulate oxidative stress, endothelial dysfunction, inflammation and vasoconstriction. Epidemiological studies have found that uric acid can independently predict the development of hypertension, as well as stroke and heart failure. Experimentally raising uric acid in animals increases blood pressure, and pilot studies suggest that lowering uric acid in humans can reduce blood pressure in hypertensive individuals. Uric acid may also have emerging roles in the pathogenesis of kidney disease, metabolic syndrome and diabetes. More studies need to be performed on the pathophysiology and clinical consequences of hyperuricaemia in cardiovascular disease.

No method is in general usage and of demonstrated effectiveness in eliminating the self-stimulatory behaviors of retardates and autistics. An Overcorrection rationale was used to develop such a method. The Overcorrection procedures consisted of a period of practice in the correct mode of the behavior contingent upon self-stimulatory behavior. The procedures were applied in a behavioral day-care program to three retarded children and one autistic child who exhibited object-mouthing, hand-mouthing, head-weaving and hand-clapping. For some behaviors, comparisons were made between the Overcorrection procedure and several alternative procedures, such as physical punishment by a slap, reinforcement for nonself-stimulatory behavior, a distasteful solution painted on the hand of a hand-mouther, and free reinforcement. The Overcorrection procedures eliminated the self-stimulatory behaviors of all four children in tutorial sessions and during the entire school day and were more effective than the alternative procedures in eliminating self-stimulation. The Overcorrection procedures appear to be rapid, enduring, and effective methods of eliminating self-stimulatory behavior.

Incontinence is a major unsolved problem in the institutional care of the profoundly retarded. A reinforcement and social analysis of incontinence was used to develop a procedure that would rapidly toilet train retardates and motivate them to remain continent during the day in their ward setting. Nine profoundly retarded adults were given intensive training (median of four days per patient), the distinctive features of which were artificially increasing the frequency of urinations, positive reinforcement of correct toileting but a delay for "accidents", use of new automatic apparatus for signalling elimination, shaping of independent toileting, cleanliness training, and staff reinforcement procedures. Incontinence was reduced immediately by about 90% and eventually decreased to near-zero. These results indicate the present procedure is an effective, rapid, enduring, and administratively feasible solution to the problem of incontinence of the institutionalized retarded.

SCIENCE under dictatorship becomes subordinated to the guiding philosophy of the dictatorship. Irrespective of other ideologic trappings, the guiding philosophic principle of recent dictatorships, including that of the Nazis, has been Hegelian in that what has been considered "rational utility" and corresponding doctrine and planning has replaced moral, ethical and religious values. Nazi propaganda was highly effective in perverting public opinion and public conscience, in a remarkably short time. In the medical profession this expressed itself in a rapid decline in standards of professional ethics. Medical science in Nazi Germany collaborated with this Hegelian trend particularly in the following enterprises: . . .

BACKGROUND: Recent data have suggested that patients with coronary disease in large arteries are at increased risk for late cardiac events after percutaneous intervention with first-generation drug-eluting stents, as compared with bare-metal stents. We sought to confirm this observation and to assess whether this increase in risk was also seen with second-generation drug-eluting stents. METHODS: We randomly assigned 2314 patients needing stents that were 3.0 mm or more in diameter to receive sirolimus-eluting, everolimus-eluting, or bare-metal stents. The primary end point was the composite of death from cardiac causes or nonfatal myocardial infarction at 2 years. Late events (occurring during months 7 to 24) and target-vessel revascularization were the main secondary end points. RESULTS: The rates of the primary end point were 2.6% among patients receiving sirolimus-eluting stents, 3.2% among those receiving everolimus-eluting stents, and 4.8% among those receiving bare-metal stents, with no significant differences between patients receiving either drug-eluting stent and those receiving bare-metal stents. There were also no significant between-group differences in the rate of late events or in the rate of death, myocardial infarction, or stent thrombosis. Rates of target-vessel revascularization for reasons unrelated to myocardial infarction were 3.7% among patients receiving sirolimus-eluting stents, 3.1% among those receiving everolimus-eluting stents, and 8.9% among those receiving bare-metal stents. The rate of target-vessel revascularization was significantly reduced among patients receiving either drug-eluting stent, as compared with a bare-metal stent, with no significant difference between the two types of drug-eluting stents. CONCLUSIONS: In patients requiring stenting of large coronary arteries, no significant differences were found among sirolimus-eluting, everolimus-eluting, and bare-metal stents with respect to the rate of death or myocardial infarction. With the two drug-eluting stents, similar reductions in rates of target-vessel revascularization were seen.

Evidence that childhood adversities are risk factors for psychosis has accumulated rapidly. Research into the mechanisms underlying these relationships has focused, productively, on psychological processes, including cognition, attachment and dissociation. In 2001, the traumagenic neurodevelopmental model sought to integrate biological and psychological research by highlighting the similarities between the structural and functional abnormalities in the brains of abused children and adults diagnosed with 'schizophrenia'. No review of relevant literature has subsequently been published. The aim of this paper, therefore, is to summarize the literature on biological mechanisms underlying the relationship between childhood trauma and psychosis published since 2001. A comprehensive search for relevant papers was undertaken via Medline, PubMed and psycINFO. In total, 125 papers were identified, with a range of methodologies, and provided both indirect support for and direct confirmation of the traumagenic neurodevelopmental model. Integrating our growing understanding of the biological sequelae of early adversity with our knowledge of the psychological processes linking early adversity to psychosis is valuable both theoretically and clinically.

Acetoacetyl-CoA thiolase and 3-hydroxy-3-methylglutaryl coenzyme synthase which comprise the 3-hydroxy-3-methylglutaryl-CoA-generating system(s) for hepatic cholesterogenesis and ketogenesis exhibit dual mitochondrial and cytoplasmic localization. Twenty to forty per cent of the thiolase and synthase of avian and rat liver are localized in the cytoplasmic compartment, the remainder residing in the mitochondria. In contrast, 3-hydroxy-3 methylglutaryl-CoA lyase, an enzyme unique to the "3-hydroxy-3-methylglutaryl-CoA cycle" of ketogenesis, appears to be localized in the mitochondrion. The small proportion, 4 to 8 percent, of this enzyme found in the cytoplasmic fraction appears to arise via leakage from the mitochondria during cell fractionation in that its properties, pI and stability, are identical to those of the mitochondrial lyase. These results are consistent with the view that ketogenesis which involves all three enzymes, acetoacetyl-CoA thiolase, 3-hydroxy-3-methylglutaryl-CoA synthase and 3-hydroxy-3-methylglutaryl-CoA lyase, occurs exclusively in the mitochondrion, whereas cholesterogenesis, a pathway which involves only the 3-hydroxy-3-methylglutaryl-CoA synthesizing enzymes, is restricted to the cytoplasm. Further fractionation of isolated mitochondria from chicken and rat liver showed that all three of the 3-hydroxy-3-methylglutaryl-CoA cycle enzymes are soluble and are localized within the matrix compartment of the mitochondrion. Likewise, cytoplasmic acetoacetyl-CoA thiolase and 3-hydroxy-3-methylglutaryl-CoA synthase are soluble cytosolic enzymes, no thiolase or synthase activity being detectable in the microsomal fraction. Chicken liver mitochondrial 3-hydroxy-3methylglutaryl-CoA synthase activity consists of a single enzymic species with a pI of 7.2, whereas the cytoplasmic activity is composed of at least two species with pI values of 4.8 and 6.7. Thus it is evident that the mitochondrial and cytoplasmic species are molecularly distinct as has been shown to be the case for the mitochondrial and cytoplasmic acetoacetyl-CoA thiolases from avian liver (Clinkenbeard, K. D., Sugiyama, T., Moss, J., Reed, W. D., and Lane, M. D. (1973) J. Biol. Chem. 248, 2275). Substantial mitochondrial 3-hydroxy-3-methylglutaryl-CoA lyase activity is present in all tissues surveyed, while only liver and kidney possess significant mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase activity. Therefore, it is proposed that tissues other than liver and kidney are unable to generate acetoacetate because they lack the mitochondrial synthase.

., solid-organ transplant recipients). Additionally, HEV-associated extrahepatic manifestations involving various organs have been reported in the last decade, although the causal link for many of them still needs to be proven. Ribavirin and interferon-alpha are the most widely used agents for the treatment of HEV infections with a certain level of success. However, ribavirin is contraindicated in pregnant patients, and interferon-alpha cannot be used in most transplant recipients. Therefore, there is an urgent need for novel antiviral compounds that are safe and effective particularly for patients having contraindications for ribavirin or interferon-alpha and infected by the ribavirin-resistant HEV. In this review article, a literature search using PubMed and MEDLINE databases was performed, up to March 2020. Only the articles published in English were reviewed.

BACKGROUND: Previous studies have suggested that clozapine is associated with increases in both weight and serum triglyceride (but not cholesterol) levels. Because of the pharmacologic similarities between clozapine and olanzapine, we decided to evaluate if olanzapine use was associated with an increase in triglycerides. METHOD: Twenty-five inpatients (21 men, 4 women) were treated with olanzapine, and their outcomes were tracked prospectively in a medication utilization evaluation study. RESULTS: After 12 weeks on a mean +/- SD dose of 13.8+/-4.4 mg/day, weight increased a mean of 12 lb (5.4 kg; from 190+/-37 lb [85.5+/-16.7 kg] to 202+/-30 lb [90.9+/-13.5 kg]), while fasting triglycerides increased a mean of 60 mg/dL (from 162+/-121 mg/dL to 222+/-135 mg/dL). Both increases were significant at p < .05. Fasting total cholesterol did not increase. The triglyceride increase was even larger when we excluded 8 patients who received various interventions to lower lipid levels (e.g., pravastatin, low-fat diet) during the olanzapine trial. There was a strong association between weight change and triglyceride change (p < .02); after controlling for weight, analysis of covariance showed no independent increase in triglycerides. CONCLUSION: These results suggest olanzapine has significant effects on weight and serum triglyceride levels. Clinical implications are discussed.

Lasers with ultrafast pulses have been developed to decrease the energy necessary to incise tissues and to decrease damage to surrounding tissues. The IntraLase femtosecond (10-15 seconds) laser has been approved by the FDA for lamellar corneal surgery. It uses an infrared (1053 nm) scanning pulse focused to 3 microm with an accuracy of 1 microm to cut a spiral pattern in the corneal stroma creating precise lamellar flaps for LASIK. Clinical studies show that the flaps are uniformly of good quality with no flap complications. The flexibility of this system allows for intrastromal corneal surgery and may make it useful for other refractive and corneal procedures.

Precancerous lesions of oral mucosa, known as potentially malignant disorders in recent years, are consists of a group of diseases, which should be diagnosed in the early stage. Oral leukoplakia, oral submucous fibrosis, and oral erythroplakia are the most common oral mucosal diseases that have a very high malignant transformation rate. Oral lichen planus is one of the potentially malignant disorders that may be seen in six different subtypes including papular, reticular, plaque-like, atrophic, erosive, and bullous type, clinically. Atrophic and erosive subtypes have the greater increased malignant transformation risk compared to another subtypes. Although there are various etiological studies, the etiology of almost all these diseases is not fully understood. Geographically, etiologic factors may vary. The most frequently reported possible factors are tobacco use, alcohol drinking, chewing of betel quid containing areca nut, and solar rays. Early diagnosis is very important and can be lifesaving, because in late stages, they may be progressed to severe dysplasia and even carcinoma in situ and/or squamous cell carcinoma. For most diseases, treatment results are not satisfactory in spite of miscellaneous therapies. While at the forefront of surgical intervention, topical and systemic treatment alternatives such as corticosteroids, calcineurin inhibitors, and retinoids are widely used.

Hyp mice having an inactivating mutation of the phosphate-regulating gene with homologies to endopeptidases on the X-chromosome (Phex) gene have bones with increased matrix extracellular phosphoglycoprotein (MEPE). An acidic, serine- and aspartic acid-rich motif (ASARM) is located in the C terminus of MEPE and other mineralized tissue matrix proteins. We studied the effects of ASARM peptides on mineralization and how PHEX and MEPE interactions contribute to X-linked hypophosphatemia (XLH). ASARM immunoreactivity was observed in the osteoid of wildtype bone and in the increased osteoid of Hyp mice. In wildtype bone, PHEX immunostaining was found particularly in osteoid osteocytes and their surrounding matrix. Treatment of MC3T3-E1 osteoblasts with triphosphorylated (3 phosphoserines) ASARM peptide (pASARM) caused a dose-dependent inhibition of mineralization. pASARM did not affect collagen deposition or osteoblast differentiation, suggesting that pASARM inhibits mineralization by direct binding to hydroxyapatite crystals. Binding of pASARM to mineralization foci in pASARM-treated cultures and to synthetic hydroxyapatite crystals was confirmed by colloidal-gold immunolabeling. Nonphosphorylated ASARM peptide showed little or no binding to hydroxyapatite and did not inhibit mineralization, showing the importance of ASARM phosphorylation in regulating mineralization. PHEX rescued the inhibition of osteoblast culture mineralization by pASARM, and mass spectrometry of cleaved peptides obtained after pASARM-PHEX incubations identified pASARM as a substrate for PHEX. These results, showing that pASARM inhibits mineralization by binding to hydroxyapatite and that this inhibitor can be cleaved by PHEX, provide a mechanism explaining how loss of PHEX activity can lead to extracellular matrix accumulation of ASARM resulting in the osteomalacia of XLH.

BACKGROUND: We sought to derive and internally validate a simple and easily applied clinical prediction rule to identify patients with nonvalvular atrial fibrillation (AF) whose stroke risk while taking aspirin is, irrespective of age, low enough that oral anticoagulation therapy is unnecessary. METHODS: We included 2501 patients with AF treated with aspirin during participation in 6 clinical trials. Patients were randomly divided into derivation and validation sets. Recursive partitioning was used to identify patients in the derivation set whose risk for stroke (ischemic or hemorrhagic) or transient ischemic attack was comparable to that observed in an age- and sex-matched cohort from the Framingham Heart Study. The derived prediction rules were tested on the validation set. RESULTS: Overall, 166 patients (6.6%) had an event during 4688.6 person-years (PYs) of observation for an incident rate of 3.5 events per 100 PYs. Patients in the derivation set classified as low risk (no previous stroke or transient ischemic attack, no treated hypertension or systolic blood pressure equal to or exceeding 140 mm Hg, no symptomatic coronary artery disease, and no diabetes) experienced 1.0 events per 100 PYs, compared with an age- and sex-matched rate of 1.2 events per 100 PYs. In the validation set, low-risk patients experienced 1.1 events per 100 PYs (expected rate of 1.2 events per 100 PYs). Low-risk patients made up 24% of the cohort and 16% of patients older than 75 years. Low-risk patients who were randomized to therapeutic oral anticoagulation therapy experienced 1.5 events per 100 PYs. CONCLUSION: Irrespective of age, patients with AF and none of these 4 clinical features and who take aspirin have stroke rates comparable to those of age-matched community cohorts and would not benefit substantially from anticoagulation.

AIMS: Recent results generated in a mouse model suggest that tumour angiogenesis/vasculogenesis can be initiated and maintained by bone marrow derived endothelial progenitor cells. This present study investigated the distribution and frequency of CD133 positive endothelial progenitor cells in patients with non-small cell lung cancer (NSCLC) (tumour tissue and tumour free lung regions) and healthy controls using fresh frozen specimens. The novel marker CD133 identifies human haemopoetic precursor cells, in addition to human endothelial progenitor cells. METHODS: Seventy nine lung cancer specimens and 66 adjacent histologically tumour free tissues of the same patient cohort were analysed; 11 postmortem specimens from control patients who did not suffer from malignant disease served as controls. Cryostat sections were stained for CD133, CD31, vascular endothelial growth factor receptor 2 (VEGFR-2; KDR), p53, and the proliferation marker Ki-67, and the correlations were analysed. RESULTS: Forty three of 63 evaluable tumour specimens had increased numbers of CD133 positive cells and in some cases capillary forming CD133 positive structures were detectable. In addition, 30 of 63 specimens had raised expression of KDR and 29 of 63 had increased MVD. Increased CD133 expression marginally correlated with raised KDR expression but not with p53 and Ki-67. CONCLUSION: A significant increase in CD133 positive cells was documented in patients with NSCLC, suggesting an involvement of endothelial progenitor cells in tumour vasculogenesis and tumour growth in these patients.

There has been a paradigm shift in professionals' perceptions of the caregiver. The challenges include: how best to support the family; improving caregiver perception of professionals; comparison of caregiver costs across illness groups; cross-cultural perspectives; longitudinal assessment for trait/statedependent characteristics; and practical assessment tools in the clinical setting. Purpose of review With a focus on publications around 2002, this paper attempts a synthetic overview of the broad range of issues in the field of family/informal caregiver burden for all categories of mental disorders. The paper seeks to answer the following questions: how far have publications advanced the field of caregiver burden; how far have they addressed the limitations of previous studies; what more needs to be done? Recent findings Although researchers accepted ‘burden’ as an ‘allencompassing’ term, many caregivers reported positive and uplifting experiences, and hence the term ‘care giving’ is proposed. Care giving is associated with emotional and cognitive transformations. The most important predictors of burden are problematical behaviour, disability and the severity of symptoms. Effective treatment is thus the first step to reduce burden. High expressed emotion may indicate the family's attempts to help the patient; and is mediated by controlling behaviour, stigma, burden, and caregiver perceptions of the patient's control over their own behaviour. New questionnaire measures of expressed emotion encourage cross-cultural research. Psycho-education is the most popular family intervention treatment. Outcome indicators that include caregiver attitudes and knowledge show more positive outcomes than readmission and caregiver burden. Encounters with health professionals are frustrating.

Patients with first-episode (FE) schizophrenia (n = 27), unipolar depression (n = 10) and bipolar disorder (n = 17) and age- and gender-matched healthy control subjects (n = 27) were administered a battery of neuropsychological (NP) tests. FE schizophrenics performed significantly less well than patients with affective disorders in the area of visual motor processing and attention. Affective disorder patients without psychotic features did not perform significantly differently to controls. However, affective disorder patients with psychotic features performed as poorly as schizophrenics, with the most pronounced impairment in the area of visual motor processing and attention. Our data tentatively suggest the existence of a dichotomy in neuropsychological impairment, with psychotic patients showing similar neuropsychological deficits, while non-psychotic affective patients perform comparably to controls.

Abstract Heparin of five commercially available brands was used to study the disappearance of heparin anticoagulant activity in normal humans. The drug was administered intravenously by bolus injection and by continuous infusion. Heparin anticoagulant activity was determined by two assays: a diluted activated partial thromboplastin time (APTT) and an assay based on inactivation of bovine factor Xa, using a clotting system. After a bolus injection, the data fitted neither single exponential nor zero-order clearance. In semilogarithmic plots, heparin anticoagulant activity disappeared according to a slightly convex curve almost always preceded by a rapid initial loss of heparin anticoagulant activity. This disappearance profile was observed with all heparin regardless of the brand or assay system. Heparin anticoagulant activity estimated by the APTT disappeared faster than heparin anticoagulant activity estimated by the anti-Xa activity in the first phase. As expected, higher anticoagulant levels with the anti-Xa assay than with the APTT were also found on continuous infusion in normals as well as in patients treated for deep vein thrombosis or pulmonary embolism. The experimental data suggested a model based on the combination of a saturable and a linear clearance mechanism. These experimental data provide reliable guidelines for adjustment of the dose of heparin in single patients.

Obstructive sleep apnoea syndrome (OSAS) often coexists in patients with chronic obstructive pulmonary disease (COPD). The present prospective cohort study tested the effect of OSAS treatment with continuous positive airway pressure (CPAP) on the survival of hypoxaemic COPD patients. It was hypothesised that CPAP treatment would be associated with higher survival in patients with moderate-to-severe OSAS and hypoxaemic COPD receiving long-term oxygen therapy (LTOT). Prospective study participants attended two outpatient advanced lung disease LTOT clinics in São Paulo, Brazil, between January 1996 and July 2006. Of 603 hypoxaemic COPD patients receiving LTOT, 95 were diagnosed with moderate-to-severe OSAS. Of this OSAS group, 61 (64%) patients accepted and were adherent to CPAP treatment, and 34 did not accept or were not adherent and were considered not treated. The 5-yr survival estimate was 71% (95% confidence interval 53-83%) and 26% (12-43%) in the CPAP-treated and nontreated groups, respectively (p<0.01). After adjusting for several confounders, patients treated with CPAP showed a significantly lower risk of death (hazard ratio of death versus nontreated 0.19 (0.08-0.48)). The present study found that CPAP treatment was associated with higher survival in patients with moderate-to-severe OSAS and hypoxaemic COPD receiving LTOT.
