Health Risk Behavior Among Justice Involved Male and Female Youth: Exploratory,Multi-Group Latent Class Analysis

Background: Youth involved in the juvenile justice system experience a disproportionate prevalence of serious mental health issues, substance abuse, and are at an increased risk of engaging in risky sexual practices. Gender differences exist, with girls at a markedly greater risk of acquiring a sexually transmitted disease. Objectives: The present study seeks to determine if there are subgroups of male and female youth who differ in their health risk behavior. If so, do any male or female subgroups at different levels of health risk differ in regard to their sociodemographic and psychological factors, and finally, what are intervention/service delivery implications of these differences. Methods: Youth were participants in an innovative health service at a centralized intake facility located in a large southeastern U.S. city. Latent class analysis and multinomial logistic regression is utilized to examine the heterogeneity of health risk behaviors across gender groups in a sample of 777 newly arrested youth. Results: Results indicate a three class solution provided the optimal fit with the data for each gender group: a Lower Health Risk group, a Higher Health Risk group, and a Highest Health Risk group. Multinomial logistic regression analysis identified significant sociodemographic and depression effects among both male and female youth. Conclusions/Importance: Youth characterized by risky sexually behavior, elevated depression, and drug involvement should be the focus of integrated intervention services. This study documents the critical need for front end, juvenile justice intake facilities to provide behavioral and public health screening, with treatment follow-up, on newly arrested youth.     

Synthesis,antimicrobial, and antioxidant activity of benzofuran barbitone and benzofuran thiobarbitone derivatives

The synthesis of novel series of benzofuran derivatives, containing barbitone moiety, 5-[(2/4-substitutedphenyl)(5-substituted-1-benzofuran-2-yl) methylidene]pyrimidin-2,4,6(1H,3H,5H)-trione (4a–i) and thiobarbitone moiety, 5-[(2/4-substitutedphenyl)(5-substituted-1-benzofuran-2-yl)methylidene]-2-thioxodihydropyrimidin-4,6(1H, 5H)-dione (5a–i) have been reported. The target compounds (4a–i) and (5a–i) were synthesized by the Knoevenagel condensation of (5-substituted-1-benzofuran-2-yl)(2/4-substitutedphenyl) methanone (3a–i) with barbituric acid and thiobarbituric acid, respectively, in acid medium. These compounds were screened for the antimicrobial and antioxidant activities. From antimicrobial activity results it was found that compounds 4a, 5a, 4c, and 5c displayed good antibacterial and antifungal activity against all tested strains. Further, the synthesized compounds were studied for docking on the enzyme, Glucosamine-6-phosphate synthase and the compounds 4c and 5c have emerged has an active antimicrobial agent with least binding energy (?5.27 and ?4.85 kJ mol^?1). Compounds 4e, 4f, 5e, and 5f showed promising free radical scavenging activity and compounds 5a and 5b showed good chelating ability with Fe²⁺ ions.     

Nutritional Factors Associated with Antenatal Depressive Symptoms in the Early Stage of Pregnancy Among Urban South Indian Women

Many women of reproductive age from developing countries have poor nutritional status, and the prevalence of depression during pregnancy is high. The objective of the present study was to assess the prevalence of antenatal depressive symptoms in early pregnancy, and to identify the demographic and nutritional factors associated with these symptoms in a sample of urban South Indian pregnant women. This cross-sectional study was the baseline assessment of a prospective randomized controlled trial of vitamin B₁₂ supplementation in urban pregnant south Indian women between the ages of 18 and 40 years (www.clinicaltrials.gov: NCT00641862). 365 women in their first trimester of pregnancy were screened for depressive symptoms at an urban clinic in Karnataka, South India, using the Kessler Psychological Distress Scale (K-10). Nutritional, clinical and biochemical factors were also assessed. Mean (SD) age of the cohort was 22.6 (3.7) years and mean (SD) BMI was 20.4 (3.3) kg/m². 121 (33 %) of the women in the 1st trimester had symptoms consistent with depression (K-10 score >6). In multivariate log binomial regression analysis, presence of antenatal depressive symptoms in the first trimester were positively associated with vomiting, prevalence ratio (PR) = 1.54 (95 % CI 1.10, 2.16) and negatively with anemia, PR = 0.67 (95 % CI 0.47, 0.96). Nutrient intakes, serum vitamin B₁₂, methylmalonic acid, homocysteine and red cell folate levels were not associated with measures of depression. Antenatal depressive symptoms in early pregnancy are highly prevalent in urban Indian women and are more common in women with vomiting and without anemia. In this cross-sectional data, blood concentrations of vitamin B₁₂ and folate were not associated with depressive symptoms. The relationship between nutritional status and depressive symptoms may require larger and longitudinal studies.     

Priority setting for children and young people with chronic conditions and disabilities

Background

The aim of this project was to identify the top 10 priorities for childhood chronic conditions and disability (CCD) research from the perspectives of children and young people with lived experience, their parents and caregivers and the professionals who work with them.

Methods

We conducted a three-stage study based on the James Lind Alliance priority-setting partnership methods. It comprised two online surveys (n = 200; n = 201) and a consensus workshop (n = 21) with these three stakeholder groups in Australia.

Results

In the first stage, 456 responses were submitted, which were coded and collapsed into 40 overarching themes. In the second stage, 20 themes were shortlisted, which were further refined in stage 3, before the top 10 priorities being selected. Of these, the top three priorities were improving awareness and inclusion in all aspects of their life (school, work and social relationships), improving access to treatments and support and improving the process of diagnosis.

Conclusions

The top 10 priorities identified reflect the need to focus on the individual, health systems and social aspects of the CCD experience when conducting research in this area.

Patient or Public Contribution

This study was guided by three Advisory Groups, comprising (1) young people living with CCD; (2) parents and caregivers of a child or young person with CCD and (3) professionals working with children and young people with CCD. These groups met several times across the course of the project and provided input into study aims, materials, methods and data interpretation and reporting. Additionally, the lead author and seven members of the author group have lived and experienced CCD.     

Synthesis and Structure-Activity Relationships of Vasicine Analogues as Bronchodilatory Agents

The series of vasicine (1) analogues, an alkaloid from Adhatoda vasica Nees., were synthesized with changes in A, B or C rings. Compounds 13-19 were evaluated for in vitro bronchodilatory activity using isolated guinea pig tracheal chain. Compounds 3-8 were also synthesized in good yields using microwave-mediated synthesis under solvent free conditions. Compounds 5 and 8 with seven-member C ring were more active than etofylline and caused 100% relaxation of both the histamine and acetycholine pre-contracted guinea pig tracheal chain. The structure-activity relationship studies showed that the quinazoline and oxo functionalities were essential for activity. The compounds without C ring and instead having aliphatic and phenyl substitutions in B ring showed relaxation against histamine pre-contracted tracheal chain only, 2-methyl substituted analogues, 12 and 13, being most active with 100% relaxation effect.     

Essential skills for purchasing — The views of directors of public health andhealth authority chief executives

Since the NHS reforms, health authorities have been purchasing health care and have been advised that publichealth considerations must inform all NHS activities, and that the Director of Public Health must be supported by a team of qualified support staff. This survey of directors of public health and health authority chief executives in England shows the skills currently available to support health authority purchasing, and the perceived importance of this wide range of skills to the purchasing process. Future models of purchasing will need to ensure access by purchasers to public health and multi-disciplinary advice.     

Auditory evoked responses during different phases of menstrual cycle

The electrophysiological correlates of changes in sensory function during menstrual cycle has already been studied and attributed to the hormonal influence. Effects of estrogen and progesterone on waves of auditory brainstem responses (ABR) have been reported and a hypothesis has been proposed that sex steroids have more influence on central auditory pathways. As mid-latency responses (MLRs) and slow vertex responses (SVRs) are better indicators of central auditory pathways, so MLRs and SVRs were also recorded besides ABRs in the present study. Waves of ABRs, MLRs & SVRs were recorded in 20 normal cycling females in 4 different phases of menstrual cycles from Cz-A1 and Cz-A2 position with alternating 90dB sound pressure click stimuli. Contralateral ear was masked with a white noise of -40 dBHL. With the same setting by changing the number of click stimuli, intervals of stimuli and filter bandpass the above 3 recordings were taken. The evoked responses in females having ovulatory cycles were compared within the four phases using ANOVA test. There is a trend of increase in peak latencies of ABR waves III and V and IPL I-V in estrogen-peak midcycle while decrease in latencies in progesterone-peak (interpeak latency) midluteal phase. Peak latencies of MLR waves No, Po, Na, Pa and Pb also show a same trend. SVR waves P2 and N2 are significantly delayed in mid-cycle (178.80 +/- 20.49, 276.65 +/- 18.32) while conduction is faster in midluteal phase (166.45 +/- 17.41, 261.95 +/- 21.07). Smallest latencies of all the waves are occurring during menstruation. These findings are suggesting that normal cyclical variations in the levels of estrogen and progesterone during menstrual cycle do affect the auditory pathways and effects are better seen on the central component.     

Polysubstance Use Among Minority Adolescent Males Incarcerated for Serious Offenses

Background

Adolescent juvenile offenders are at high risk for problems associated with drug use, including polysubstance use (i.e., use of a variety of drugs). The combination of juvenile offending and polysubstance use presents a significant public and child health concern.

Objective

This study explored polysubstance use among a sample of youth incarcerated for serious offenses. We examined several risk factors for substance use and delinquency (i.e., early and frequent substance use, prior history of arrests, school expulsion, Black ethnicity), as well as the association between aggression and polysubstance use.

Methods

Data were collected via questionnaires from 373 serious male juvenile offenders upon intake into a secure locked facility. Youth were on average 16 years old, and minority youth were overrepresented (28.1 % Black, 53.1 % Latino). Poisson regressions were used to assess the associations between the risk factors, aggression, and polysubstance use.

Results

Consistent with the literature, Black youth reported less polysubstance use and later age of drug use onset than White and Latino youth. Findings suggest that Latino juvenile offenders and those with an early and problematic pattern of substance use are at heightened risk for polysubstance use. Aggression was not significantly related to polysubstance use, over and above the risk factors.

Conclusions

Given that Latino youth experience low rates of treatment for substance use, the development of culturally-sensitive interventions for these youth is needed. Interventions should also be multifaceted to address the multitude of risk factors associated with polysubstance use among juvenile offenders.

     

Azaepothilone B and its derivatives: a patent review

Introduction: Azaepothilone B, also known as ixabepilone, is a semi synthetic second generation epothilone B analogue. Azaepothilone B, its derivatives, and analogues, are used for treating advance metastatic breast cancer. It has been used as a chemotherapeutic medication for cancer.

Areas covered: This review highlights the patents on different routes for synthesis of azaepothilone B, its derivatives and analogues. The review will also provide the reported pharmacological activity and its polymorphs in the treatment of several cancers, such as breast cancer (metastatic or locally advanced), non-Hodgkin’s lymphoma, and pancreatic cancer. In addition, it considers other proliferative diseases such as viral infections, degenerative diseases of the musculoskeletal system, kidney disease, and immune response related diseases. Different databases such as Espacenet, ISI Web of Knowledge, Patbase, and Thomson Innovation have been searched extensively to review the patents. The analysis has been done to indicate the patenting trend across years and the comparison of active assignees.

Expert opinion: Azaepothilone B, along with its derivatives and analogues, can damage cancer cells in very low concentrations and retain its activity when tumor cells are insensitive to paclitaxel. Hence, it is highly potent agent. Azaepothilone B alone, in combination with other chemotherapeutics, or in the form of formulations, led to applications in various types of cancer. Also, antiproliferative activity of azaepothilone B has great potential for the treatment of proliferative diseases, such as skin diseases and infections. Recent progress in synthesizing azaepothilone B has encouraged researchers to develop new methods for the synthesis of azaepothilone B, its derivatives, and analogues, to obtain maximum yield in minimum steps.
