Awareness data on cervical cancer among females of rural and urban areas of Haryana, India

A cross-sectional study was done to assess the degree of current awareness and behaviors about cervical cancer among females in urban and rural areas of North India. This survey was conducted on one thousand females (500 rural and 500 urban). A well-structured questionnaire was designed to collect information about participants' knowledge on cancer of cervix uteri such as age, height and weight measurements, marital status, menstrual status, personal hygiene, age at menarche, sexual history, pregnancy and abortion history, use of contraceptive pills for birth-control, smoking, alcohol consumption, and other relevant information. The data was collected by conducting face-to-face interviews after obtaining the verbal consent of the participants. The data has the potential to reduce disease burden by spreading awareness about symptoms and risk factors of cervical cancer as well as implementation of effective early screening strategies.

Chemical technology principles for selective bioconjugation of proteins and antibodies

Proteins are multifunctional large organic compounds that constitute an essential component of a living system. Hence, control over their bioconjugation impacts science at the chemistry-biology-medicine interface. A chemical toolbox for their precision engineering can boost healthcare and open a gateway for directed or precision therapeutics. Such a chemical toolbox remained elusive for a long time due to the complexity presented by the large pool of functional groups. The precise single-site modification of a protein requires a method to address a combination of selectivity attributes. This review focuses on guiding principles that can segregate them to simplify the task for a chemical method. Such a disintegration systematically employs a multi-step chemical transformation to deconvolute the selectivity challenges. It constitutes a disintegrate (DIN) theory that offers additional control parameters for tuning precision in protein bioconjugation. This review outlines the selectivity hurdles faced by chemical methods. It elaborates on the developments in the perspective of DIN theory to demonstrate simultaneous regulation of reactivity, chemoselectivity, site-selectivity, modularity, residue specificity, and protein specificity. It discusses the progress of such methods to construct protein and antibody conjugates for biologics, including antibody-fluorophore and antibody-drug conjugates (AFCs and ADCs). It also briefs how this knowledge can assist in developing small molecule-based covalent inhibitors. In the process, it highlights an opportunity for hypothesis-driven routes to accelerate discoveries of selective methods and establish new targetome in the precision engineering of proteins and antibodies.

Differential localization of dengue virus protease affects cell homeostasis and triggers to thrombocytopenia

Thrombocytopenia is one of the symptoms of many virus infections which is the "hallmark" in the case of dengue virus. In this study, we show the differential localization of existing two forms of dengue virus protease, i.e., NS2BNS3 to the nucleus and NS3 to the nucleus and mitochondria. We also report a nuclear transcription factor, erythroid differentiation regulatory factor 1 (EDRF1), as the substrate for this protease. EDRF1 regulates the expression and activity of GATA1, which in turn controls spectrin synthesis. Both GATA1 and spectrins are required for platelet formation. On the other hand, we found that the mitochondrial activities will be damaged by NS3 localization which cleaves GrpEL1, a co-chaperone of mitochondrial Hsp70. Levels of both EDRF1 and GrpEL1 were found to deteriorate in dengue virus-infected clinical samples. Hence, we conclude that NS2BNS3-mediated EDRF1 cleavage and the NS3-led mitochondrial dysfunction account for thrombocytopenia.

istegrate (DIN) Theory Enabling Precision Engineering of Proteins

The chemical toolbox for the selective modification of proteins has witnessed immense interest in the past few years. The rapid growth of biologics and the need for precision therapeutics have fuelled this growth further. However, the broad spectrum of selectivity parameters creates a roadblock to the field's growth. Additionally, bond formation and dissociation are significantly redefined during the translation from small molecules to proteins. Understanding these principles and developing theories to deconvolute the multidimensional attributes could accelerate the area. This outlook presents a disintegrate (DIN) theory for systematically disintegrating the selectivity challenges through reversible chemical reactions. An irreversible step concludes the reaction sequence to render an integrated solution for precise protein bioconjugation. In this perspective, we highlight the key advancements, unsolved challenges, and potential opportunities.

Feasibility and Acceptability of a Remote Stepped Care Mental Health Programme for Adolescents during the COVID-19 Pandemic in India

Remote mental health services were rapidly deployed during the COVID-19 pandemic, yet there is relatively little contemporaneous evidence on their feasibility and acceptability. This study assessed the feasibility and acceptability of a stepped care mental health programme delivered remotely by lay counsellors to adolescents in New Delhi, India, during a period of 'lockdown'. The programme consisted of a brief problem-solving intervention ("Step 1") followed by a tailored behavioural module ("Step 2") for non-responders. We enrolled 34 participants (M age = 16.4 years) with a self-identified need for psychological support. Feasibility and acceptability were assessed through quantitative process indicators and qualitative interviews (n = 17 adolescents; n = 5 counsellors). Thirty-one (91%) adolescents started Step 1 and 16 (52%) completed the planned Step 1 protocol. Twelve (75%) of the Step 1 completers were non-responsive. Eight (67%) non-responsive cases started Step 2, all of whom met response criteria when reassessed at 12 weeks post-enrolment. Adolescents favoured voice-only sessions over video-calls due to privacy concerns and difficulties accessing suitable devices. Counsellors noted challenges of completing remote sessions within the allotted time while recognising the importance of supervision for developing competence in new ways of working. Both adolescents and counsellors discussed the importance of working collaboratively and flexibly to fit around individual preferences and circumstances. Disentangling pandemic-specific barriers from more routine challenges to remote delivery should be a focus of future research.

Respiratory illness virus infections with special emphasis on COVID-19

Viruses that emerge pose challenges for treatment options as their uniqueness would not know completely. Hence, many viruses are causing high morbidity and mortality for a long time. Despite large diversity, viruses share common characteristics for infection. At least 12 different respiratory-borne viruses are reported belonging to various virus taxonomic families. Many of these viruses multiply and cause damage to the upper and lower respiratory tracts. The description of these viruses in comparison with each other concerning their epidemiology, molecular characteristics, disease manifestations, diagnosis and treatment is lacking. Such information helps diagnose, differentiate, and formulate the control measures faster. The leading cause of acute illness worldwide is acute respiratory infections (ARIs) and are responsible for nearly 4 million deaths every year, mostly in young children and infants. Lower respiratory tract infections are the fourth most common cause of death globally, after non-infectious chronic conditions. This review aims to present the characteristics of different viruses causing respiratory infections, highlighting the uniqueness of SARS-CoV-2. We expect this review to help understand the similarities and differences among the closely related viruses causing respiratory infections and formulate specific preventive or control measures.

Exogenous administration of hydrogen sulfide alleviates homocysteine induced inflammation in ARPE-19 cells

Plasma homocysteine (Hcy) is an independent risk factor for Age related macular degeneration (AMD) and an inducer of inflammation. Homocysteine catabolism releases hydrogen sulfide (H₂S). H₂S has controversial effects on inflammation. In this study we have analysed the endogenous and exogenous H₂S in modulating inflammation using adult retinal pigment epithelial (ARPE-19) cells as an in vitro model for AMD. ARPE-19 cells were treated with various concentrations of Hcy (15, 30 and 50 μM) for 3 h. Expression of Hcy transulfuration genes (CBS, CSE) by qPCR and western blot. H₂S levels were measured using Free Radical Analyzer System (WPI, USA). The inflammatory markers (IL-6 and IL-8) were evaluated using real-time PCR and ELISA. Hcy exposure increased CBS protein expression, hydrogen sulfide levels and pro-inflammatory cytokines, modulating CBS by silencing did not alter H₂S levels, but inhibition of CSE with PAG inhibited H₂S production and decreased cytokine (IL-6 and IL-8) levels. On the contrary exogenous supply of hydrogen sulfide with NaHS and by compound 1c showed anti-inflammatory effects even in the presence of Hcy. This study shows that exogenous delivery of H₂S decreases inflammation in retinal pigment epithelial cells on exposure to Hcy in ARPE-19 cells.

An Examination of Downward Drift as an Explanation of the Relationship Between Childhood Maltreatment and Residence in Unhealthy Neighborhoods in Adulthood: The Role of Psychiatric Symptoms

This study sought to determine whether downward drift explains relationships among childhood maltreatment, psychiatric disorders, and residence in unhealthy neighborhoods. Using data from a prospective cohort design study, individuals with court substantiated cases of child abuse and/neglect (ages 0-11 during the years 1967-1971) and matched controls were followed up in adulthood. Mental health symptoms and neighborhood disadvantage were measured in young (M_age  = 29) and middle adulthood (M_age  = 40). Physical disorder and social cohesion were also measured in middle adulthood. Childhood maltreatment increased risk for more symptoms of depression, anxiety, and illicit drug use in young adulthood and depression and anxiety in middle adulthood. Childhood maltreatment negatively impacted neighborhood residence in young and middle adulthood, increasing a person's risk of living in neighborhoods with higher levels of physical disorder and economic disadvantage, and lower levels of social cohesion. Neighborhood disadvantage in young adulthood did not increase risk for psychiatric symptoms in middle adulthood. With one exception, neighborhood disadvantage earlier in life, not psychiatric symptoms, helped explain the relationship between childhood maltreatment and living in unhealthy neighborhoods. The negative impact of childhood maltreatment was evident earlier in life and continued into middle adulthood.

Seasonal dynamics and impact factors of atmospheric CO2 concentration over subtropical forest canopies: observation from eddy covariance tower and OCO-2 satellite in Northwest Himalaya, India

Carbon dioxide (CO₂) is the key atmospheric gas that controls the earth's greenhouse effect, and forests play a major role in abating the atmospheric CO₂ by storing carbon as biomass. Therefore, it is vital to understand the role of different forests in regulating the spatiotemporal dynamics of atmospheric CO₂ concentration. In this study, we have used eddy covariance (EC) tower-based atmospheric CO₂ concentration measurements and satellite-retrieved column average CO₂ concentration of 2018 to understand the diurnal and seasonal dynamics of atmospheric CO₂ concentration over the sub-tropical forest in the foothills of northwest Himalaya, Uttarakhand, India. EC study revealed that the CO₂ concentration over the forest canopy peaks during mid-night to early morning and drop to a minimum during the afternoon. On a monthly scale, peak atmospheric CO₂ concentration was observed during July in both the sites, which was a result of more release of CO₂ by the forest ecosystem through ecosystem respiration and microbial decomposition. Enhanced photosynthetic activities during the late monsoon and post-monsoon resulted in the decrease of atmospheric CO₂ concentration over the forest ecosystem. Among the meteorological variables, rainfall was found to have the highest control over the seasonal variability of the atmospheric CO₂ concentration. Orbiting Carbon Observatory-2 (OCO-2) satellite-retrieved column average CO₂ (XCO₂) was also examined to comprehend its reliability on an ecosystem scale. The OCO-2 retrieved XCO₂ value was higher than the EC carbon flux tower-measured atmospheric CO₂ concentration, which might be due to differences in the vertical resolution of the CO₂ column and scale difference. However, the monthly atmospheric XCO₂ retrieved from OCO-2 strongly adheres with the ground-measured monthly pattern. Our study highlights that forests with varying functional traits within the same climatic conditions show variability in the regulation of atmospheric CO₂ concentration.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Peptidoglycan-treated tumor antigen-pulsed dendritic cells impart complete resistance against tumor rechallenge

Solid tumors elicit suppressive T cell responses which impair antigen-presenting cell (APC) functions. Such immune suppression results in uncontrolled tumor growth and mortality. Addressing APC dysfunction, dendritic cell (DC)-mediated anti-tumor vaccination was extensively investigated in both mice and humans. These studies never achieved full resistance to tumor relapse. Herein, we describe a repetitive RM-1 murine tumor rechallenge model for recurrence in humans. Using this newly developed model, we show that priming with tumor antigen-pulsed, Toll-like receptor (TLR)2 ligand-activated DCs elicits a host-protective anti-tumor immune response in C57BL/6 mice. Upon stimulation with the TLR2 ligand peptidoglycan (PGN), the tumor antigen-pulsed DCs induce complete resistance to repetitive tumor challenges. Intra-tumoral injection of PGN reduces tumor growth. The tumor resistance is accompanied by increased expression of interleukin (IL)-27, T-box transcription factor TBX21 (T-bet), IL-12, tumor necrosis factor (TNF)-α and interferon (IFN)-γ, along with heightened cytotoxic T lymphocyte (CTL) functions. Mice primed four times with PGN-stimulated tumor antigen-pulsed DCs remain entirely resistant to repeat challenges with RM-1 tumor cells, suggesting complete prevention of relapse and recurrence of tumor. Adoptive transfer of T cells from these mice, which were fully protected from RM-1 rechallenge, confers anti-tumor immunity to syngeneic naive recipient mice upon RM-1 challenge. These observations indicate that PGN-activated DCs induce robust host-protective anti-tumor T cells that completely resist tumor growth and recurrence.

Small molecule generators of biologically reactive sulfur species

Sulfur metabolism is integral to cellular growth and survival. The presence of a wide range of oxidation states of sulfur in biology coupled with its unique reactivity are some key features of the biology of this element. In particular, nearly all oxidation states of sulfur not only occur but are also inter-convertible. In order to study the chemical biology of reactive sulfur species, tools to reliably detect as well as generate these species within cells are necessary. Herein, an overview of strategies to generate certain reactive sulfur species is presented. The donors of reactive sulfur species have been organized based on their oxidation states. These interesting small molecules have helped lay a strong foundation to study the biology of reactive sulfur species and some may have therapeutic applications in the future as well.

Reactive Oxygen Species-Triggered Tunable Hydrogen Sulfide Release

A series of carbamothioates with tunable release of H₂S after activation by reactive oxygen species are reported. The half-lives of H₂S release could be tuned from 24 to 203 min by varying the basicity of the amine.

Unpacking Pretrial Detention: An Examination of Patterns and Predictors of Readmissions

Pretrial detention makes up the majority of jail admissions, but little is known about this high-volume population. The current study fills this gap by examining the pretrial detention population in New York City and assesses their pretrial readmissions over a 10-year follow-up period. While the number of individuals detained pretrial has consistently decreased since 1995, the prevalence and the frequency of pretrial readmissions remain high: About 60% of the sample was readmitted at least once within 10 years and they were readmitted on average 3 times. A negative binomial model predicting readmission counts for felony and misdemeanor admissions found that males, non-Hispanic Blacks, and younger individuals were more frequently readmitted pretrial. Self-reported drug use and prior criminal records were associated with higher readmission counts. We also found that charge and discharge types predicted readmission counts. Findings suggest the importance of earlier intervention and developing targeted strategies to reduce further readmissions.

Criminal responsibility: Meta-analysis and study space

While some correlates of criminal responsibility (CR) outcomes are consistent, others are not. Study-level characteristics, such as sample selection, variability in the operational definition of insanity, or other unknown influences may explain discrepant findings. It is critical to systematically consolidate and assess the literature in order to guide future work. We conducted the first meta-analysis and study space analysis (see Malpass et al., ) in this area. 15 studies met inclusion criteria for the meta-analysis, which encompassed 19,500 cases. Summary effects for psycholegal cases indicated that older age, female sex, educational attainment, and unemployment were associated with insanity. Those classified insane more often had psychiatric histories and psychotic disorders. Finally, individuals opined or found insane were less likely to have criminal histories but more likely to have been opined incompetent to stand trial in the past. Importantly, virtually all summary effects were impacted by study design. Study space analyses (N = 7) revealed a dearth of literature that thoroughly addressed theoretically important variables. Taken together, the project provides a comprehensive, empirical analysis of CR correlates and a systematic call for future research.

Pronator teres accessorius: A new variant in flexor antebrachial musculature

Muscles of flexor compartment of forearm have a common origin from medial epicondyle of humerus. Additional bellies of flexor muscles are commonly reported but presence of supernumerary muscles is an infrequent phenomenon. The present study describes an unusual muscle mass in flexor compartment of forearm simulating pronator teres. During routine dissection the upper limb of a 50 years old male cadaver, a supernumerary muscle was found on left side of the upper limb in the flexor compartment. The origin of the muscle was 2cm wide and aponeurotic in nature and attached to an oblique line extending from the inferior surface of the medial epicondyle and the medial surface of the trochlea. It was inserted on an oblique line 2.5cm wide on the radius in area between supinator superiorly and flexor digitorum profundus inferiorly. Existence of accessory muscles, which connect flexor muscles, could be explained embryologically by incomplete cleavage of flexor mass during development. The flexor muscles of the forearm develop from the flexor mass which subsequently divides into two layers: superficial and deep. The deep layer gives rise to flexor digitorum superficialis, flexor digitorum profundus and flexor pollicis longus. These supernumerary muscles are extremely rare entities and probably represent deranged embryological development or the process of atavism in which the anomalous part persist for a longer time in the tree of evolution.

BIOBETTERS: THE BETTER BIOLOGICS AND THEIR REGULATORY OVERVIEW

The continuous innovation of the biopharmaceutical industry has led to development of a new category of biopharmaceuticals i.e. Biobetters or Biosuperiors. Biobetters may have better efficacy, a longer half-life, lower dosing frequency, a reduced risk of immunogenicity, reduced toxicity and side effects along with lower early-stage research risk and development costs. Biobetters rather than biosimilars may capture significant share of market and are the next wave for companies to ride on. Although it sounds intuitive, biobetters will have to face various ordeals like identification of the apparent unmet need, quantification of the potential market opportunity, expensive investment in clinical trials, challenging regulatory approval, pressures of price erosion and patent litigations. Thus, development of biobetters truly requires the right balance between providing life-changing medical management for patients and maintaining an innovative pipeline for continued business success. This review will focus on technical and regulatory prospects of biobetters.

Does adult attachment style mediate the relationship between childhood maltreatment and mental and physical health outcomes?

Attachment theory has been proposed as one explanation for the relationship between childhood maltreatment and problematic mental and physical health outcomes in adulthood. This study seeks to determine whether: (1) childhood physical abuse and neglect lead to different attachment styles in adulthood, (2) adult attachment styles predict subsequent mental and physical health outcomes, and (3) adult attachment styles mediate the relationship between childhood physical abuse and neglect and mental and physical health outcomes. Children with documented cases of physical abuse and neglect (ages 0-11) were matched with children without these histories and followed up in adulthood. Adult attachment style was assessed at mean age 39.5 and outcomes at 41.1. Separate path models examined mental and physical health outcomes. Individuals with histories of childhood neglect and physical abuse had higher levels of anxious attachment style in adulthood, whereas neglect predicted avoidant attachment as well. Both adult attachment styles (anxious and avoidant) predicted mental health outcomes (higher levels of anxiety and depression and lower levels of self-esteem), whereas only anxious adult attachment style predicted higher levels of allostatic load. Path analyses revealed that anxious attachment style in adulthood in part explained the relationship between childhood neglect and physical abuse to depression, anxiety, and self-esteem, but not the relationship to allostatic load. Childhood neglect and physical abuse have lasting effects on adult attachment styles and anxious and avoidant adult attachment styles contribute to understanding the negative mental health consequences of childhood neglect and physical abuse 30 years later in adulthood.

Child Maltreatment, Problem Behaviors, and Neighborhood Attainment

Using data from a prospective cohort design study of a group of children with documented histories of abuse and neglect (n = 908) and matched controls (n = 667), this paper examines whether problem behaviors (e.g., prostitution, crime, school problems, and homelessness) in young adulthood explain the link between maltreatment in childhood and living in high-risk neighborhoods in middle adulthood. Problem behaviors were assessed at mean age of 29 and neighborhood characteristics were assessed at mean age of 40. Child maltreatment predicted living in less desirable neighborhoods in middle adulthood. Problem behaviors in young adulthood partially mediated the relationship between childhood maltreatment and residence in less desirable neighborhoods in middle adulthood. The direct paths from child maltreatment to neighborhoods were not significant for Black children. For White children, there was a direct relationship between child maltreatment and living in an economically disadvantaged neighborhood. Problem behaviors were a stronger mediator between child maltreatment and living in more disordered and less socially cohesive neighborhoods for Black children, while the problem behaviors were a stronger mediator for living in more economically disadvantaged and less socially cohesive neighborhoods for White children. Further research is needed to understand these racial differences. Interventions should focus on preventing problem behaviors to minimize the risk of residency in high-risk neighborhoods.

Visible-Light-Triggered Uncaging of Carbonyl Sulfide for Hydrogen Sulfide (H2S) Release

Generation of hydrogen sulfide (H₂S) is challenging and few methods are capable of localized delivery of this gas. Here, a boron dipyrromethene-based carbamothioate (BDP-H₂S) that is uncaged by visible light of 470 nm to generate carbonyl sulfide (COS), which is rapidly hydrolyzed to H₂S in the presence of carbonic anhydrase, a widely prevalent enzyme, is reported.

Redundant and regulatory roles for Toll-like receptors in Leishmania infection

Toll-like receptors (TLRs) are germline-encoded, non-clonal innate immune receptors, which are often the first receptors to recognize the molecular patterns on pathogens. Therefore, the immune response initiated by TLRs has far-reaching consequences on the outcome of an infection. As soon as the cell surface TLRs and other receptors recognize a pathogen, the pathogen is phagocytosed. Inclusion of TLRs in the phagosome results in quicker phagosomal maturation and stronger adaptive immune response, as TLRs influence co-stimulatory molecule expression and determinant selection by major histocompatibility complex (MHC) class II and MHC class I for cross-presentation. The signals delivered by the TCR-peptide-MHC complex and co-stimulatory molecules are indispensable for optimal T cell activation. In addition, the cytokines induced by TLRs can skew the differentiation of activated T cells to different effector T cell subsets. However, the potential of TLRs to influence adaptive immune response into different patterns is severely restricted by multiple factors: gross specificity for the molecular patterns, lack of receptor rearrangements, sharing of limited number of adaptors that assemble signalling complexes and redundancy in ligand recognition. These features of apparent redundancy and regulation in the functioning of TLRs characterize them as important and probable contributory factors in the resistance or susceptibility to an infection.

"On demand" redox buffering by H2S contributes to antibiotic resistance revealed by a bacteria-specific H2S donor

Understanding the mechanisms of antimicrobial resistance (AMR) will help launch a counter-offensive against human pathogens that threaten our ability to effectively treat common infections. Herein, we report bis(4-nitrobenzyl)sulfanes, which are activated by a bacterial enzyme to produce hydrogen sulfide (H2S) gas. We found that H2S helps maintain redox homeostasis and protects bacteria against antibiotic-triggered oxidative stress "on demand", through activation of alternate respiratory oxidases and cellular antioxidants. We discovered, a hitherto unknown role for this gas, that chemical inhibition of H2S biosynthesis reversed antibiotic resistance in multidrug-resistant (MDR) uropathogenic Escherichia coli strains of clinical origin, whereas exposure to the H2S donor restored drug tolerance. Together, our study provides a greater insight into the dynamic defence mechanisms of this gas, modes of antibiotic action as well as resistance while progressing towards new pharmacological targets to address AMR.

Combined evaluations of competency to stand trial and mental state at the time of the offense: An overlooked methodological consideration?

Combined evaluations of competency to stand trial (CST; competency) and mental state at the time of the offense (MSO; sanity) frequently co-occur. However, most research examines the 2 as discrete constructs without considering 4 potential combined evaluation outcomes: competent-sane, incompetent-sane, competent-insane, and incompetent-insane. External validity can be improved if research more closely mirrored practice. It may be incorrect to assume incompetent defendants are similar across CST-only and combined evaluations, and insane defendants are similar across MSO-only and combined evaluations. Using a sample of 2,751 combined evaluations, we examined demographic, clinical, offense, evaluation, and psycholegal characteristics associated with evaluators' combined evaluation opinions. Multinomial regression analyses revealed older defendants were more likely to be opined incompetent-insane. Defendants with psychotic disorders were more often opined insane, regardless of competency status. Affective diagnoses predicted competent-insane opinions. Developmental disorders were closely related to incompetence, regardless of sanity status. Defendants with organic disorders tended to have global psycholegal impairment, in that they were more often opined incompetent-insane, incompetent-sane, or competent-insane, relative to competent-sane. Prior hospitalization predicted competent-insane relative to competent-sane opinions. Defendants not under the influence of a substance during the offense or with no prior convictions were more likely to be opined insane, regardless of competency status. We interpret these findings in light of psycholegal theory and provide recommendations for research and practice. Collectively, results suggest incorporation of combined evaluations into CST and MSO research is an important methodological consideration not to be overlooked. (PsycINFO Database Record

Esterase Activated Carbonyl Sulfide/Hydrogen Sulfide (H2S) Donors

Hydrogen sulfide (H₂S) is a mediator of a number of cellular processes, and modulating cellular levels of this gas has emerged as an important therapeutic area. Localized generation of H₂S is thus very useful but highly challenging. Here, we report pivaloyloxymethyl-based carbonothioates and carbamothioates that are activated by the enzyme, esterase, to generate carbonyl sulfide (COS), which is hydrolyzed to H₂S.

Neighborhood Context and Binge Drinking by Race and Ethnicity in New York City

BACKGROUND

Neighborhood context is associated with binge drinking and has significant health, societal, and economic costs. Both binge drinking and neighborhood context vary by race and ethnicity. We examined the relations between neighborhood characteristics--neighborhood norms that are accepting of drunkenness, collective efficacy, and physical disorder--and binge drinking, with a focus on examining race and ethnic-specific relationships.

METHODS

Respondent data were collected through 2005 random digit-dial-telephone survey for a representative sample of New York City residents; neighborhood data were based on the 2005 New York City Housing and Vacancy Survey. Participants were 1,415 past-year drinkers; Whites (n = 877), Blacks (n = 292), and Hispanics (n = 246). Generalized estimating equations were used to estimate population average models.

RESULTS

For the overall sample, neighborhood norms that were more accepting of drunkenness were associated with greater binge drinking (odds ratio [OR] = 1.22; 95% confidence interval [CI] = 1.09, 1.37); collective efficacy and physical disorder were not significant. However, when examining this by race/ethnicity, greater collective efficacy (OR = 0.75; 95% CI = 0.62, 0.91) and greater physical disorder (OR = 0.76; 95% CI = 0.62, 0.93) were associated with less binge drinking for Whites only. Neighborhood norms that were more accepting of drunkenness were associated with binge drinking among Whites (OR = 1.20; 95% CI = 1.05, 1.38) and, while not significant (perhaps due to power), the associations were similar for Hispanics (OR = 1.18; 95% CI = 0.83, 1.68) and slightly lower for Blacks (OR = 1.11; 95% CI = 0.67, 1.84).

CONCLUSIONS

Overall, results suggest that neighborhood characteristics and binge drinking are shaped, in part, by factors that vary across race/ethnicity. Thus, disaggregating data by race/ethnicity is important in understanding binge drinking behaviors.

Quality and Acceptability of Meat Nuggets with Fresh Aloe vera Gel

Aloe vera has been used worldwide for pharmaceutical, food, and cosmetic industries due to its wide biological activities. However, quality improvement of low fat meat products and their acceptability with added Aloe vera gel (AVG) is scanty. The aim of this study was to explore the feasibility of using fresh AVG on physicochemical, textural, sensory and nutritive qualities of goat meat nuggets. The products were prepared with 0%, 2.5%, and 5% fresh AVG replacing goat meat and were analyzed for proximate composition, physicochemical and textural properties, fatty acid profile and sensory parameters. Changes in lipid oxidation and microbial growth of nuggets were also evaluated over 9 days of refrigerated storage. The results showed that AVG significantly (p<0.05) decreased the pH value and protein content of meat emulsion and nuggets. Product yield was affected at 5% level of gel. Addition of AVG in the formulation significantly affected the values of texture profile analysis. The AVG reduced the lipid oxidation and microbial growth in nuggets during storage. Sensory panelists preferred nuggets with 2.5% AVG over nuggets with 5% AVG. Therefore, AVG up to 2.5% level could be used for quality improvement in goat meat nuggets without affecting its sensorial, textural and nutritive values.

The effect of various oral hygiene products on the microbial flora in patients undergoing orthodontic treatment

Context

Orthodontic devices lead to significantly greater plaque accumulation and gingival inflammation resulting in a change of gingival flora from cocci and rods to motile organisms like spirochetes.

Aims

The aim was to study the effect of various oral hygiene products on the microbial flora in patients undergoing orthodontic treatment.

Materials and Methods

The microbial composition of 40 patients, divided into four groups of 10 patients each, was evaluated. Group I patients were prescribed nonfluoridated dentifrice which act as the control group, Group II patients were given fluoridated dentifrice while in Group III and Group IV fluoridated mouth rinse and cetylpyridinium chloride mouth rinse, respectively, along with nonfluoridated toothpaste was prescribed. The plaque sample was collected at the start of orthodontic treatment, after 30 days, 60 days and 90 days for all the patients. The microscopic slides were prepared and observed under dark field microscopy at the magnification of ×1000 and microbes were classified as cocci, spirochetes, fusiforms, filaments, and rods.

Results

After applying analysis of variance and Tukey honest significant difference test, it was observed that after 30 days, only the proportion of filaments was found to be significantly higher in Group I. After 60 days, Group I had significantly lower proportion of cocci and a higher proportion of rods as compared to other groups. After 90 days, Group I had significantly higher count of rods, filaments, fusiforms, and spirochetes as compared to Groups III and IV.

Conclusion

Less amount of the microbial shift to the pathogenic organisms was seen in the patients in whom mouthwashes along with tooth brushing were prescribed.

Competency to stand trial among female inpatients

Competency to stand trial evaluations are conducted by forensic mental health professionals to opine whether defendants possess the mental abilities to understand, appreciate, and reason in regard to their court proceedings. The majority of research on competency to stand trial evaluations has focused on males, with research on female defendants being relatively underexplored. Even less is known of diverse female samples referred for competency evaluation. In the current study, we sought to examine whether characteristics associated with competency among predominantly male samples translate to a racially, ethnically, and culturally diverse group of female defendants (N = 288, 85% non-White). Chi-square analyses revealed significant relationships between findings of incompetence and defendants' diagnosis of a psychotic disorder, active psychotic symptoms, medication noncompliance, nonparticipation in the evaluation, and nonfelony charges. Logistic regression analysis indicated that defendants who experienced active psychotic symptoms, did not participate in their evaluations, and were not compliant with their medication were most likely to be found incompetent. Notably, neither minority status nor age was a significant characteristic in predicting incompetence. These findings in particular differ from much of the literature and highlight the need to examine competency within a cross-cultural framework, as characteristics associated with competency opinions do not necessarily translate across demographic groups.

Do the long-term consequences of neglect differ for children of different races and ethnic backgrounds?

Scant research has examined how children of different races or ethnic backgrounds manifest consequences of neglect. We examined multiple domains of functioning (academic/intellectual, social/behavioral, and psychiatric), three theories (racial invariance, double jeopardy, and resilience), and potential confounding variables. Children with documented cases of neglect (ages 0-11) and matched controls without such histories were followed up and interviewed in adulthood (N = 1,039). The sample was 47.3% female, 62.4% White, 34.3% Black, and 3.4% Hispanic. Black and White neglected children showed negative consequences for IQ, reading ability, and occupational status compared to controls. Compared to same race and ethnic group controls, neglected White children showed extensive mental health consequences, Black children showed more anxiety and dysthymia, and Hispanic children showed increased risk for alcohol problems. Black and White neglected children differed in risk for violence compared to same race controls: Neglected Black children were arrested for violence two times more often than Black controls, whereas neglected White children were more likely than White controls to report engaging in violence. Findings provide some support for each theory (racial invariance, double jeopardy, and resilience). Understanding the factors that account for similarities and differences in consequences requires further investigation. Implications for research and policy are discussed.

Comparing the Youth Psychopathic Traits Inventory (YPI) and the Psychopathy Checklist–Youth Version (PCL-YV) Among Offending Girls

Using a multimeasure longitudinal research design, we measured psychopathy with the Youth Psychopathic Traits Inventory (YPI) and the Psychopathy Checklist–Youth Version (PCL-YV) among 122 offending girls. We examined the psychometric properties of the YPI, investigated the association between the YPI and the PCL-YV, and assessed their concurrent and longitudinal association with externalizing problems on the Youth/Adult Self-Report and violent and delinquent behaviors on the Self-Report of Offending. Alphas for the YPI were adequate and there were small to moderate correlations between the YPI and PCL-YV, suggesting that each assesses distinctive personality features. The YPI and the PCL-YV were approximately equivalent in their association with concurrent and longitudinal outcomes with two exceptions, where the YPI demonstrated a stronger association with antisocial behavior. Concurrently, there was a divergent relationship between the psychopathy factor scores and antisocial outcomes. Within 2 years, the psychopathy affective factor, which constrained the YPI and PCL-YV to be equivalent, was associated with externalizing behaviors and the YPI affective factor was associated with violent offending. Approximately 4½ years later, neither measure was significantly related to antisocial behavior after accounting for past behavior. Reasons for continuity and discontinuity in risk identification are discussed.
