Status of Females in the Juvenile Justice System Iowa, 2009

Young women in the juvenile justice system present with characteristics and experiences that differentiate them from their male counterparts. As such, the juvenile justice system in Iowa must consider these factors if it is to effectively and efficiently impact recidivism, rehabilitation and public safety. Data reveal the following trends: All youth in the juvenile justice system experience a significantly higher rate of child maltreatment than do youth in the general population. Additionally, young women have a distinctly higher percentage of reported sexual abuse. Young women commit primarily non-violent offenses, with shoplifting and running away being the only two areas where they exceed young men in number. Young women are held in detention for a substantially higher percentage of misdemeanor versus felony offenses than young men. Young women of color, particularly African American females, are far more likely to come into contact with the juvenile justice system. Additionally, arrests of minority females have increased during the same time frame as arrests of Caucasian females have decreased. The general type of offense committed by young women is against public order (i.e. alcohol related violations, disorderly conduct) or property (i.e. shoplifting), though young women with subsequent charges of a violent nature are likely to have had violent offenses initially as well. Historically, young women have been a smaller segment of the juvenile justice population. They remain so today. Consequently, they are easy to overlook. But Iowa’s response to them is no less important. Perhaps, because they are fewer in number, our system can have a true and meaningful influence, with prevention of further penetration into both the juvenile and adult systems being the ultimate goal. The Iowa Task Force on Young Women recommends the following measures to facilitate movement toward that goal: 1. Facilities and programs striving to provide the most effective and efficient services to young women will opt for single gender environments with female responsive programming that includes components to address trauma. 2. All institutions and agencies that work with females involved in the juvenile justice system and which receive state funding should be required to provide annual female responsive training to their employees. Training should be research based, progressive, ongoing and result in an implementation plan. 3. As detention reform proceeds, gender and the disproportionate number of females in detention for misdemeanor offenses must be an integral part of policy and decision making discussions including any recommendations for solutions to be implemented. 4. As research, data and planning progresses related to disproportionate minority contact with the juvenile system, the needs of girls of color be given equal consideration. Specifically, assessment tools must be without race/ethnic bias and they must also be female responsive.

Juvenile antioxidant treatment prevents adult deficits in a developmental model of schizophrenia.

Abnormal development can lead to deficits in adult brain function, a trajectory likely underlying adolescent-onset psychiatric conditions such as schizophrenia. Developmental manipulations yielding adult deficits in rodents provide an opportunity to explore mechanisms involved in a delayed emergence of anomalies driven by developmental alterations. Here we assessed whether oxidative stress during presymptomatic stages causes adult anomalies in rats with a neonatal ventral hippocampal lesion, a developmental rodent model useful for schizophrenia research. Juvenile and adolescent treatment with the antioxidant N-acetyl cysteine prevented the reduction of prefrontal parvalbumin interneuron activity observed in this model, as well as electrophysiological and behavioral deficits relevant to schizophrenia. Adolescent treatment with the glutathione peroxidase mimic ebselen also reversed behavioral deficits in this animal model. These findings suggest that presymptomatic oxidative stress yields abnormal adult brain function in a developmentally compromised brain, and highlight redox modulation as a potential target for early intervention.

Early stage disc degeneration does not have an appreciable affect on stiffness and load transfer following vertebroplasty and kyphoplasty.

Vertebroplasty and kyphoplasty have been reported to alter the mechanical behavior of the treated and adjacent-level segments, and have been suggested to increase the risk for adjacent-level fractures. The intervertebral disc (IVD) plays an important role in the mechanical behavior of vertebral motion segments. Comparisons between normal and degenerative IVD motion segments following cement augmentation have yet to be reported. A microstructural finite element model of a degenerative IVD motion segment was constructed from micro-CT images. Microdamage within the vertebral body trabecular structure was used to simulate a slightly (I = 83.5% of intact stiffness), moderately (II = 57.8% of intact stiffness), and severely (III = 16.0% of intact stiffness) damaged motion segment. Six variable geometry single-segment cement repair strategies (models A-F) were studied at each damage level (I-III). IVD and bone stresses, and motion segment stiffness, were compared with the intact and baseline damage models (untreated), as well as, previous findings using normal IVD models with the same repair strategies. Overall, small differences were observed in motion segment stiffness and average stresses between the degenerative and normal disc repair models. We did however observe a reduction in endplate bulge and a redistribution in the microstructural tissue level stresses across both endplates and in the treated segment following early stage IVD degeneration. The cement augmentation strategy placing bone cement along the periphery of the vertebra (model E) proved to be the most advantageous in treating the degenerative IVD models by showing larger reductions in the average bone stresses (vertebral and endplate) as compared to the normal IVD models. Furthermore, only this repair strategy, and the complete cement fill strategy (model F), were able to restore the slightly damaged (I) motion segment stiffness above pre-damaged (intact) levels. Early stage IVD degeneration does not have an appreciable effect in motion segment stiffness and average stresses in the treated and adjacent-level segments following vertebroplasty and kyphoplasty. Placing bone cement in the periphery of the damaged vertebra in a degenerative IVD motion segment, minimizes load transfer, and may reduce the likelihood of adjacent-level fractures.

Low income, community poverty and risk of end stage renal disease

BACKGROUND: The risk of end stage renal disease (ESRD) is increased among individuals with low income and in low income communities. However, few studies have examined the relation of both individual and community socioeconomic status (SES) with incident ESRD. METHODS: Among 23,314 U.S. adults in the population-based Reasons for Geographic and Racial Differences in Stroke study, we assessed participant differences across geospatially-linked categories of county poverty [outlier poverty, extremely high poverty, very high poverty, high poverty, neither (reference), high affluence and outlier affluence]. Multivariable Cox proportional hazards models were used to examine associations of annual household income and geospatially-linked county poverty measures with incident ESRD, while accounting for death as a competing event using the Fine and Gray method. RESULTS: There were 158 ESRD cases during follow-up. Incident ESRD rates were 178.8 per 100,000 person-years (105 py) in high poverty outlier counties and were 76.3 /105 py in affluent outlier counties, p trend = 0.06. In unadjusted competing risk models, persons residing in high poverty outlier counties had higher incidence of ESRD (which was not statistically significant) when compared to those persons residing in counties with neither high poverty nor affluence [hazard ratio (HR) 1.54, 95% Confidence Interval (CI) 0.75-3.20]. This association was markedly attenuated following adjustment for socio-demographic factors (age, sex, race, education, and income); HR 0.96, 95% CI 0.46-2.00. However, in the same adjusted model, income was independently associated with risk of ESRD [HR 3.75, 95% CI 1.62-8.64, comparing the < $20,000 income group to the > $75,000 group]. There were no statistically significant associations of county measures of poverty with incident ESRD, and no evidence of effect modification. CONCLUSIONS: In contrast to annual family income, geospatially-linked measures of county poverty have little relation with risk of ESRD. Efforts to mitigate socioeconomic disparities in kidney disease may be best appropriated at the individual level.

High specificity of line-immunoassay based algorithms for recent HIV-1 infection independent of viral subtype and stage of disease.

ABSTRACT: BACKGROUND: Serologic testing algorithms for recent HIV seroconversion (STARHS) provide important information for HIV surveillance. We have shown that a patient's antibody reaction in a confirmatory line immunoassay (INNO-LIATM HIV I/II Score, Innogenetics) provides information on the duration of infection. Here, we sought to further investigate the diagnostic specificity of various Inno-Lia algorithms and to identify factors affecting it. METHODS: Plasma samples of 714 selected patients of the Swiss HIV Cohort Study infected for longer than 12 months and representing all viral clades and stages of chronic HIV-1 infection were tested blindly by Inno-Lia and classified as either incident (up to 12 m) or older infection by 24 different algorithms. Of the total, 524 patients received HAART, 308 had HIV-1 RNA below 50 copies/mL, and 620 were infected by a HIV-1 non-B clade. Using logistic regression analysis we evaluated factors that might affect the specificity of these algorithms. RESULTS: HIV-1 RNA <50 copies/mL was associated with significantly lower reactivity to all five HIV-1 antigens of the Inno-Lia and impaired specificity of most algorithms. Among 412 patients either untreated or with HIV-1 RNA ≥50 copies/mL despite HAART, the median specificity of the algorithms was 96.5% (range 92.0-100%). The only factor that significantly promoted false-incident results in this group was age, with false-incident results increasing by a few percent per additional year. HIV-1 clade, HIV-1 RNA, CD4 percentage, sex, disease stage, and testing modalities exhibited no significance. Results were similar among 190 untreated patients. CONCLUSIONS: The specificity of most Inno-Lia algorithms was high and not affected by HIV-1 variability, advanced disease and other factors promoting false-recent results in other STARHS. Specificity should be good in any group of untreated HIV-1 patients.

Some like it hot: temperature and acidification modulate larval development and settlement of the sea urchin Arbacia lixula

We studied the effects of temperature and pH on larval development, settlement and juvenile survival of a Mediterranean population of the sea urchin Arbacia lixula. Three temperatures (16, 17.5 and 19 °C) were tested at present pH conditions (pHT 8.1). At 19 °C, two pH levels were compared to reflect present average (pHT 8.1) and near-future average conditions (pHT 7.7, expected by 2100). Larvae were reared for 52-days to achieve the full larval development and complete the metamorphosis to the settler stage. We analyzed larval survival, growth, morphology and settlement success. We also tested the carry-over effect of acidification on juvenile survival after 3 days. Our results showed that larval survival and size significantly increased with temperature. Acidification resulted in higher survival rates and developmental delay. Larval morphology was significantly altered by low temperatures, which led to narrower larvae with relatively shorter skeletal rods, but larval morphology was only marginally affected by acidification. No carry-over effects between larvae and juveniles were detected in early settler survival, though settlers from larvae reared at pH 7.7 were significantly smaller than their counterparts developed at pH 8.1. These results suggest an overall positive effect of environmental parameters related to global change on the reproduction of A. lixula, and reinforce the concerns about the increasing negative impact on shallow Mediterranean ecosystems of this post-glacial colonizer.

Role of hepatocyte wounding on " Plasmodium " liver-stage development and survival

RESUME La première étape primordiale au cycle de vie du Plasmodium dans un hôte mammifère est l'invasion des hepatocytes par des sporozoites. L'infection finale des hepatocytes est précédée de la traversée de plusieurs cellules hôtes, rompant les membranes plasmiques et ayant comme résultat la sécrétion des facteurs cytotoliques dans le micro-environnement. Ce matériel endogène libéré est fortement stimulant/immunogène et peut servir de signal de danger initiant des réponses distinctes dans diverses cellules. De nos jours, le caractère essentiel et salutaire de la migration des sporozoites comme étape d'infection du Plasmodium est vivement controversée. Ainsi, notre étude a visé à caractériser l'effet de l'interaction du parasite avec ses cellules hôtes d'un point de vue immunologique. En particulier, nous avons voulu évaluer l'effet de la perte de matériel cellulaire pendant l'infection de Plasmodium sur les hepatocytes primaires de souris et sur des cultures cellulaires HepG2. Nous avons observé que les facteurs cytotoxiques dérivés des cellules endommagés activent NF-κB - un important régulateur de réponse inflammatoires -dans des cellules voisines des cellules endommagés, qui sont des cellules hôtes potentielles pour l'infection finale du parasite. Cette activation de NF-κB s'est produite peu de temps après l'infection et a mené in vitro et in vivo à une réduction d'infection de façon dépendante du temps, un effet qui a pu être compensé par l'addition de BAY11-7082, un inhibiteur spécifique de NF-κB. De plus, aucune activation de NF-κB avec des parasites SPECT-/-, incapables de traverser les hepatocytes, n'a été observée. Nous avons montré parla suite que l'activation de NF-κB induit l'expression de l'enzyme iNOS dans les hepatocytes, qui est responsable d'une diminution des hepatocytes infectés. En outre, les hepatocytes primaires des souris MyD88-/- n'ont montré ni activation de NF-κB, ni expression d'iNOS lors de l'infection, ce qui suggère la participation des membres de famille du Toll/IL-1 récepteur dans la reconnaissance des facteurs cytosoxiques. En effet, le manque de MyD88 a augmenté significativement l'infection in vitro et in vivo. D'autre part, un rôle bénéfique pour l'activation de NF-κB a été évalué. Les cellules infectées étaient plus résistantes contre l'apoptose induite par Fas (CD95/Apo-1) que les cellules non infectées ou les cellules infectées dans lesquelles NF-κB a été bloqué par BAY11-7082 in vitro. Paradoxalement, l'expression d'iNOS contribue à la protection des cellules infectées contre l'apoptose pax Fas, puisque le traitement avec l'inhibiteur spécifique SMT (S-methylisothiourea) a rendu les cellules infectées plus susceptibles à l'apoptose. Un effet bénéfique additionnel pour le parasite est que la plupart des cellules hôtes traversées présentent des peptides du parasite aux cellules T cytotoxiques spécifiques et peuvent donc réorienter la réaction immune spécifique sur les cellules non infectées. Nous montrons que les cellules hôtes endommagés par la migration du parasite induit l'inflammation, qui limite l'ampleur de l'infection. D'autre part, nos données soutiennent que la survie du parasite Plasmodium dans le foie est assurée par une augmentation de la résistance des hepatocytes contre l'apoptose. SUMMARY The first obligatory step of the Plasmodium life cycle in the mammalian host is the invasion of hepatocytes by sporozoites. Final hepatocyte infection involves the penetration of several host cells, whose plasma membranes are ruptured in the process, resulting in the release of cytosolic factors into the microenvironment. This released endogenous material is highly stimulatory / immunogenic and can serve as a danger signal initiating distinct responses in various cells. To date, it is highly controversial whether sporozoite migration through hepatocytes is an essential and beneficial step for Plasmodium infection. Thus, our study aimed at characterizing the effect of the interaction of the parasite with its host cells from an immunological point of view In particular, we wanted to evaluate the effect of cell material leakage during Plasmodium infection on cultured mouse primary hepatocytes and HepG2 cells. We observed that wounded cell-derived cytosolic factors activate NF-κB - a main regulator of host inflammatory responses - in cells bordering wounded cells, which are potential host cells for final parasite infection. This activation of NF-κB occurred shortly after infection and led to a reduction of infection load in a time dependent manner in vitro and in viva, an effect that could be reverted by addition of the specific NF-κB inhibitor BAY11-7082. In addition, no NF-κB activation was observed when SPECT-/- parasites, which are devoid of hepatocyte traversing properties, were used. We provide further evidence that NF-κB activation causes the induction of inducible nitric oxide synthase (iNOS) expression in hepatocytes, and this is, in turn, responsible for a decrease in Plasmodium-infected hepatocytes. Furthermore, primary hepatocytes from MyD88-/- mice showed no NF-κB activation and iNOS expression upon infection, suggesting a role of the Toll/IL-1 receptor family members in sensing cytosolic factors. Indeed, lack of MyD88 significantly increased infection in vitro and in vivo. In a further complementary series of experiments, we assessed a possible beneficial role for the activation of NF-κB. Infected cells were more resistant to Fas (CD95/Apo-1)-mediated apoptosis than uninfected cells or infected cells in which NF-κB was blocked by BAYl1-7082 in vitro. Paradoxically, iNOS expression contributes to the protection of infected cells from Fas-induced apoptosis, since treatment with the specific iNOS inhibitor SMT (S-Methylisothiourea Sulfate) rendered the infected cells more susceptible to apoptosis. An additional beneficial effect of host cell traversal for the parasite is the fact that mainly traversed cells present parasite-derived peptides to specific cytotoxic T cells and therefore may redirect the specific immune response to uninfected cells. In summary, we have shown that host cells wounded by parasite migration induce inflammation, which limits the extent of parasite infection. In addition, our data support the notion that survival of Plasmodium parasites in the liver is mediated by increasing the resistance of hepatocytes to Fas-induced apoptosis.

Eyes wide shut - unusual two stage repair of pectus excavatum and annuloaortic ectasia in a 37 year old marfan patient: Case report

We report about a 37 year old male patient with a pectus excavatum. The patient was in NYHA functional class III. After performed computed tomography the symptoms were thought to be related to the severity of chest deformation. A Ravitch-procedure had been accomplished in a district hospital in 2009. The crack of a metal bar led to a reevaluation 2010, in which surprisingly the presence of an annuloaortic ectasia (root 73 × 74 mm) in direct neighborhood of the formerly implanted metal-bars was diagnosed. Echocardiography revealed a severe aortic valve regurgitation, the left ventricle was massively dilated presenting a reduced ejection fraction of 45%. A marfan syndrome was suspected and the patient underwent a valve sparing aortic root replacement (David procedure) in our institution with an uneventful postoperative course. A review of the literature in combination with discussion of our case suggests the application of stronger recommendations towards preoperative cardiovascular assessment in patients with pectus excavatum.

Surrogate decision making for patients with end-stage dementia.

OBJECTIVE: We aim to explore how health surrogates of patients with dementia proceed in decision making, which considerations are decisive, and whether family surrogates and professional guardians decide differently. METHODS: We conducted an experimental vignette study using think aloud protocol analysis. Thirty-two family surrogates and professional guardians were asked to decide on two hypothetical case vignettes, concerning a feeding tube placement and a cardiac pacemaker implantation in patients with end-stage dementia. They had to verbalize their thoughts while deciding. Verbalizations were audio-recorded, transcribed, and analyzed according to content analysis. By experimentally changing variables in the vignettes, the impact of these variables on the outcome of decision making was calculated. RESULTS: Although only 25% and 31% of the relatives gave their consent to the feeding tube and pacemaker placement, respectively, 56% and 81% of the professional guardians consented to these life-sustaining measures. Relatives decided intuitively, referred to their own preferences, and focused on the patient's age, state of wellbeing, and suffering. Professional guardians showed a deliberative approach, relied on medical and legal authorities, and emphasized patient autonomy. Situational variables such as the patient's current behavior and the views of health care professionals and family members had higher impacts on decisions than the patient's prior statements or life attitudes. CONCLUSIONS: Both the process and outcome of surrogate decision making depend heavily on whether the surrogate is a relative or not. These findings have implications for the physician-surrogate relationship and legal frameworks regarding surrogacy. Copyright © 2011 John Wiley & Sons, Ltd.

Sequential or concomitant chemotherapy in limited stage small-cell lung cancer.

PURPOSE: Chemotherapy (CT) combined with radiation therapy (RT) is the standard treatment for limited disease small-cell lung cancer (LDSCLC). Many questions including RT dose, fractionation, and sequence of RT/CT administration remain controversial. In this paper, we retrospectively assessed the outcome of patients with LDSCLC treated with radiation of at least 50 Gy.METHODS AND MATERIALS: From December 1997 to January 2006, 69 consecutive patients with LDSCLC were treated at our institutions. Treatment consisted of at least 4 cycles of CT, and 3D conformal thoracic RT. The median age was 61 years (range, 37-78 years). Sequential or concomitant CT/RT was given in 47 (68%) and 22 (32%) of the patients, respectively. The median RT dose was 60 Gy. Prophylactic cranial irradiation (PCI) was administered in 47 (68%) patients.RESULTS: With a median follow-up of 36 months (range, 6-107), 16 patients were alive without disease. The median overall survival time was 24 months, with a 3-year survival rate of 29%. The 3-year disease-free survival (DFS) and loco-regional control (LRC) rates were 23% and 60%, respectively. A better DFS was significantly associated with performance status (PS) 0 (p = 0.004), complete response to treatment (p = 0.03), and PCI group (p = 0.03). A trend towards improved overall survival (OS) was observed for patients who underwent PCI (p = 0.07). Patients treated with sequential CT/RT had a better outcome than those treated with concomitant treatment (3-year DFS rate 27% vs. 13%; p = 0.04). However, PCI was delivered more frequently for the sequential group. No significant dose-response relationship was found in terms of LRC. The multivariate analysis showed that complete response to treatment was the only significant factor for OS.CONCLUSION: Complete response to treatment was the most important factor for OS. A better DFS was significantly associated with the PCI group. We did not find a significant difference in outcome between patients receiving doses of 60 Gy or more and patients receiving 60 Gy or less.
