Towards a youth mental health paradigm: a perspective and roadmap.

Most mental disorders have a typical onset between 12 and 25 years of age, highlighting the importance of this period for the pathogenesis, diagnosis, and treatment of mental ill-health. This perspective addresses interactions between risk and protective factors and brain development as key pillars accounting for the emergence of psychopathology in youth. Moreover, we propose that novel approaches towards early diagnosis and interventions are required that reflect the evolution of emerging psychopathology, the importance of novel service models, and knowledge exchange between science and practitioners. Taken together, we propose a transformative early intervention paradigm for research and clinical care that could significantly enhance mental health in young people and initiate a shift towards the prevention of severe mental disorders.

Structural Investigation and Optical Properties of Dysprosium (Dy3+) Ions Doped Oxyfluoro Antimony Borate Glasses for Photonics Applications.

Dysprosium oxide-doped glasses with a composition of 60B2O3-10Sb2O3-10Al2O3-10NaF-(10-x) LiF-xDy2O3 (x = 0.1,0.5, 1.0,1.5,2.0,2.5 mol%) were prepared using a conventional melt-quenching technique. The glasses were characterized through various analytical investigations, including X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, refractive index, density, optical absorption, excitation, photoluminescence (PL) studies, decay measurements and radiation shielding parameters. The XRD and FT-IR confirms the glassy nature and functional groups present in the titled glass. The absorption spectra were used to determine the oscillator strength of the Dy3+ absorption transitions as well as the bond created with the O-2 ion in the titled glass network. The degree of the suitability of developed glasses for lasing applications was demonstrated by radiative parameters determined using Judd-Ofelt theory. In the prepared glass samples, the optical bandgap measurements indicate the presence of non-bridging oxygen (NBOs), localization of charges and donor centers in the titled glasses. Due to the de-excitation of 4F9/2 to the corresponding 6H15/2,6H13/2 and 6H11/2 states, the PL emission spectrum shows two main strong emissions at blue(480nm), yellow (575nm) and one less emission at red (663nm). The CIE coordinates determined using PL emission spectra reveal the coordinates that are falling within the white light region. Various shielding parameters such as mass attenuation coefficient, mean free path, effective atomic number were estimated to understand the radiative shielding nature of the titled glasses. Within the addition of Dy2O3, it was found that the shielding parameters values of the titled glass samples are increasing. The Mass Attenuation Coefficient, Half Value Layer and Mean Free Path of the as prepared glasses has been compared with different types of concretes to understand the shielding effectiveness of prepared glass.

The role of patient perceptions and hyperfunctional voice disorders in predicting voice therapy attendance.

OBJECTIVES/HYPOTHESIS: Attendance is essential to voice therapy's effectiveness in the treatment of voice and laryngeal disorders. With such high rates of drop-out and non-attendance, it is important to understand the factors that influence this behavior. This study sought to identify potential predictors of attendance to voice therapy at an interdisciplinary voice clinic. STUDY DESIGN: Single-institution retrospective cohort study. METHODS: In this retrospective cohort study, patients evaluated at an interdisciplinary voice clinic who received a referral for voice therapy were identified. Age, gender, voice-related diagnoses, Voice Handicap Index-10 scores, Reflux Symptom Index scores, and measures of patient perceptions (self-rated severity, importance of voice in one's life, and "feelings about voice therapy") were recorded to evaluate associations with attendance to at least one therapy session. Standard statistical analysis and logistic regressions were performed. RESULTS: Of 168 subjects included, 111 (66.1 %) attended at least one session of voice therapy. Patients diagnosed with primary hyperfunctional voice disorders had a significantly higher attendance rate than other groups. Attenders had higher self-ratings of severity and more positive "feelings about voice therapy" compared to non-attenders. Regression models found three significant predictors of therapy attendance: primary diagnosis of hyperfunctional voice disorder, self-rated severity, and "feelings about voice therapy." CONCLUSION: In this cohort, patients with more positive feelings about voice therapy, higher self-rated severity, and a diagnosis of primary hyperfunctional voice disorder were more likely to attend voice therapy.

Obesity-alleviating potential of asiatic acid and its effects on ACC1, UCP2, and CPT1 mRNA expression in high fat diet-induced obese Sprague-Dawley rats.

The present study evaluated the effects of asiatic acid (AA), a pentacyclic triterpenoid from Centella asiatica on lipid metabolism parameters in a rat model of obesity induced using a high fat diet (HFD) for 42 days. AA (20 mg/kg body weight [BW]) was administered orally once daily for 42 days, and an orlistat-treated group of rats (10 mg/kg BW) was included for comparison. Changes in BW, blood glucose levels, insulin resistance and leptin, adiponectin, amylase, and lipase levels in the blood; lipid profiles of plasma; liver antioxidants levels; and acetyl CoA carboxylase(ACC), uncoupling protein-2 (UCP2), and carnitine palmitoyltransferase-1 (CPT1) mRNA expression were observed in the experimental rats. Our results revealed that AA (20 mg/kg BW), similar to orlistat, reduced the increase in BW; increased bone mineral contents and bone mineral densities; reduced blood glucose levels, insulin resistance, leptin, plasma lipid levels; increased adiponectin, amylase, lipase levels in the blood; showed antioxidant activity; and altered mRNA expression of lipid metabolism-related genes, including ACC, UCP 2, and CPT 1, in the HFD-fed rats. From these results, we concluded that AA possesses significant anti-obesity potential through the suppression of BW gain, lipid lowering action, development of insulin and leptin sensitivity, antioxidant activity, and increased mRNA expression of lipid metabolism-related genes.

Integrated (one-stop shop) youth health care: best available evidence and future directions.

Although mental health problems represent the largest burden of disease in young people, access to mental health care has been poor for this group. Integrated youth health care services have been proposed as an innovative solution. Integrated care joins up physical health, mental health and social care services, ideally in one location, so that a young person receives holistic care in a coordinated way. It can be implemented in a range of ways. A review of the available literature identified a range of studies reporting the results of evaluation research into integrated care services. The best available data indicate that many young people who may not otherwise have sought help are accessing these mental health services, and there are promising outcomes for most in terms of symptomatic and functional recovery. Where evaluated, young people report having benefited from and being highly satisfied with these services. Some young people, such as those with more severe presenting symptoms and those who received fewer treatment sessions, have failed to benefit, indicating a need for further integration with more specialist care. Efforts are underway to articulate the standards and core features to which integrated care services should adhere, as well as to further evaluate outcomes. This will guide the ongoing development of best practice models of service delivery.

Studies on effect of oat and cheese incorporation on sensory and textural quality of short-dough type biscuit.

In view of their growing importance in human nutrition, incorporation of oats and cheese during the manufacture of short-dough type biscuits was studied. Rolled oats were incorporated at 25, 35 and 45 % of refined wheat flour in short-dough type biscuit formulation. Cheddar and processed cheese were used for flavouring purpose at three levels each, viz. 30, 40 and 50 % on flour basis. The dough exhibited less firmness on oats incorporation as indicated by lower firmness value (21.73 N) as against 25.05 N for control dough measured by Texture Analyser. Addition of cheese to the 25 % oat incorporated dough further reduced its firmness and altered its viscoelastic characteristics. Baking conditions for the oats and cheese incorporated biscuits were optimized as 165 °C for 25-27 min. Sensory evaluation results revealed that the biscuit made from 25 % oat incorporated dough scored highest in most of the sensory attributes including overall acceptability. Cheddar cheese and processed cheese levels were optimized at 30 and 40 % in oats-incorporated dough based on the sensory analysis of biscuits prepared from the dough samples. The moisture and ß- glucan contents were 3.93 % and 0.62 %; 4.32 % and 0.60 % for cheddar cheese and processed cheese added biscuits, respectively. The spread ratios were higher in cheese incorporated biscuits than in oat incorporated biscuits. It was concluded that good quality cheese flavoured biscuits can be prepared by incorporating rolled oats in biscuit formulation along with cheddar or processed cheese.

Structural changes in response to bioaccumulation of iron and mercury in Chromolaena odorata (L.) King & Robins.

A comparative study was designed to elucidate the effect of iron and mercury on the morphological and anatomical changes as well as bioaccumulation potential in Chromolaena odorata. Plants were grown in half-strength Hoagland nutrient medium artificially contaminated with known quantities of HgCl2 (15 µM) and FeCl3 (1000 µM). Bioaccumulation of Hg and Fe was maximum in the root, and comparatively reduced bioaccumulation was recorded in the stem and leaves. Microscopic studies on morphology and anatomy revealed development of trichomes and lenticels on the stem and modified trichomes on leaves. Localized deposits of stained masses in various internal parts of the root, stem and leaf also were observed. Differential adaptation/strategy of C. odorata to attain tolerance towards Hg and Fe and phytoremediation potential of the plant is discussed.

Colour tunable photoluminescence studies of Dy3+/Eu3+ co-doped BaPbAlFB glasses for epoxy-free w-LED applications.

Barium lead alumino fluoroborate (BaPbAlFB) glasses singly and co-doped with Dy3+ and Eu3+ ions were prepared by melt quench method and studied their photoluminescence (PL) properties along with energy migration. Singly doped Dy3+/Eu3+ ions in BaPbAlFB glasses under 365 and 393 nm excitation wavelengths emit the PL bands through Dy: (4F9/2 → 6H15/2 and 4F9/2 → 6H13/2) and Eu: (5D0→7F2) transitions located at (Dy: 483 and 575 nm) and (Eu: 613 nm) respectively. Further, tunability of PL emissions is achieved by exciting the Dy3+/Eu3+ co-doped BaPbAlFB glasses at various wavelengths. The obtained CIE (0.34, 0.33) and CCT value (5080.4 K) of Dy3+/Eu3+ co-doped BaPbAlFB glass produced white light emission under 365 nm excitation wavelength. The corresponding CCT values of Dy3+/Eu3+ co-doped BaPbAlFB glasses varied from 1580 to 5080 K and their corresponding color emission changes from intense red to white light regime quite suitable for fabrication of epoxy-free w-LED devices.

The relationship between therapeutic alliance, frequency of consultation and uptake of telemedicine among patients seeking treatment for early psychosis: A moderated mediation model.

Background: Telehealth services ensure the delivery of healthcare services to a wider range of consumers through online platforms. Nonetheless, the acceptance and uptake of telehealth remain elusive. This study aims to understand the (a) uptake and (b) acceptability of telemedicine, (c) if therapeutic alliance mediates the relationship between the frequency of consultations with clinicians and the uptake of telemedicine in patients with early psychosis, and (d) role of education in moderating the relationship between therapeutic alliance and the uptake of telemedicine for their mental healthcare. Methods: A convenience sample of outpatients (n = 109) seeking treatment for early psychosis and their care providers (n = 106) were recruited from a tertiary psychiatric care centre. Sociodemographic and clinical characteristics, therapeutic alliance (Working Alliance Inventory), and telemedicine use were captured through self-administered surveys. The moderated mediation analysis was performed using PROCESS macro 3.4.1 with therapeutic alliance and level of education as the mediating and moderating factors, respectively. Results: The acceptance of telemedicine was high (possibly will use: 47.7%; definitely will use: 26.6%) whilst the uptake was low (11%). Therapeutic alliance mediated the relationship between the frequency of consultation and the uptake of telemedicine (ß: 0.326; CI: 0.042, 0.637). This effect was moderated by the level of education (ß: -0.058; p < 0.05). Conclusion: Therapeutic alliance mediates the relationship between the frequency of consultations and the uptake of telemedicine services with the level of education moderating this mediation. Focusing on the patients with lower education to improve their telemedicine knowledge and therapeutic alliance might increase the uptake.

Mapping the schizophrenia quality of life scale to EQ-5D, HUI3 and SF-6D utility scores in patients with schizophrenia.

OBJECTIVES: The current study aimed to map the disease-specific Schizophrenia Quality of Life Scale (SQLS) onto the three- and five-level EuroQol five-dimension (EQ-5D-3 L and EQ-5D-5 L), Health Utility Index Mark 3 (HUI3) and Short Form six-dimensional (SF-6D) preference-based instruments to inform future cost-utility analyses for treatment of patients with schizophrenia. METHODS: Data from 251 outpatients with schizophrenia spectrum disorders was included for analysis. Ordinary least square (OLS), Tobit and beta regression mixture models were employed to estimate the utility scores. Three regression models with a total of 66 specifications were determined by goodness of fit and predictive indices. Distribution of the original data to the distributions of the data generated using the preferred estimated models were then compared. RESULTS: EQ-5D-3 L and EQ-5D-5 L were best predicted by the OLS model, including SQLS domain scores, domain-squared scores, age, and gender as explanatory predictors. The models produced the best performance index and resembled most closely with the observed EQ-5D data. HUI3 and SF-6D were best predicted by the OLS and Tobit model respectively. CONCLUSION: The current study developed mapping models for converting SQLS scores into generic utility scores, which can be used for economic evaluation among patients with schizophrenia.

A cross-sectional study on the frequency and risk factors for neonatal hypoglycemia in babies born in rural Kerala.

Introduction: Glucose is the main source of energy for the developing brain. Hypoglycemia is a commonly encountered and treatable problem in the neonatal period. The newborn baby should be breastfed soon after delivery and continued on demand breastfeeding. As families become nuclear, mothers may not have the necessary skills and knowledge about the importance of exclusive breastfeeding. Health care workers play an important role in preparing the mothers for exclusive breastfeeding and ensuring that the newborn remains euglycemic. Problems encountered during breastfeeding should be corrected on an individual basis, and uninterrupted feeding should be ensured as per BFHI guidelines. Aim: To find out the frequency and risk factors of hypoglycemia and its relation to feeding in babies of GDM mothers, large for gestational age, and small for gestational age babies in a baby-friendly hospital adhering to the BFHI guidelines. Materials and Methods: A single-center, observational study was carried out among 160 consecutively born babies born to mothers with gestational diabetes, large for gestational age and small for gestational age for a period of one year from October 2018 to September 2019. Data was collected using an interviewer administered proforma and from antenatal and postnatal records. Glucose monitoring was done and values were recorded. Data was analysed using SPSS software. Qualitative data was expressed as percentage. and quantitative data was expressed as mean and standard deviation. Association with risk factors was studied using the Chi-squared test. Results: The overall incidence of hypoglycemia was 15.3% in our study. The main risk factors identified were prematurity and small for gestational age. Maximum incidence of hypoglycemia was noted in the first 24 hours after birth. Incidence of hypoglycemia in exclusively breastfed babies was only 10.5% compared to those on formula feeds where breastfeeding was contraindicated due to medical reasons and where the incidence was found to be 33.3%. Incidence of hypoglycemia was 50%. The most common symptoms of hypoglycemia were jitteriness and poor feeding. Eleven per cent of babies had asymptomatic hypoglycemia. In babies detected to have hypoglycemia, prompt treatment with oral feeds or intravenous (IV) dextrose was started. There was no mortality in the study population. Conclusion: Incidence of hypoglycemia was maximum in the first hour of life, highlighting the need to start early feeds and to do meticulous monitoring in high-risk babies like pre-term babies, small for gestational age, large for gestational age and babies of diabetic mothers. The incidence of hypoglycemia in exclusively the breastfed group was 10.5%. This showed that confident and successful breastfeeding with the support of health care staff should be the norm to prevent hypoglycemia, and preparation for breastfeeding should begin right from the antenatal period.

An Unexpected Role for Cell Density Rather than IgM in Cell-Surface Display of the Fc Receptor for IgM on Human Lymphocytes.

The Fc receptor for IgM, FcMR, is unusual in that it is preferentially expressed by cells of the adaptive immune system. It is, moreover, the only constitutively expressed Fc receptor on human T cells. Efforts to decipher the normal functions of FcMR have been complicated by species-specific expression patterns in lymphocytes from mice (B cells) versus humans (B, NK, and T cells). In human cells, FcMR cell-surface expression has been reported to be low at baseline ex vivo, with one suggested contribution being ligand-induced internalization by serum IgM. Indeed, preincubation overnight in IgM-free culture medium is recommended for studies of FcMR because surface display is increased under these conditions. We investigated FcMR display on human lymphocytes in PBMCs and found that, surprisingly, cell-surface FcMR was unaffected by IgM abundance and was instead downregulated in high-cell density cultures by a yet undefined mechanism. We further found that ex vivo processing of whole blood decreased surface FcMR, supporting the idea that FcMR expression is likely to be greater on circulating lymphocytes than previously appreciated. Collectively, these findings prompt new predictions of where and when FcMR might be available for functional interactions in vivo.

Lifetime Prevalence and Correlates of Schizophrenia and Other Psychotic Disorders in Singapore.

Introduction: The current study aimed to establish the lifetime prevalence of schizophrenia and other psychotic disorders, its sociodemographic correlates and association with physical disorders using data from the Singapore Mental Health Study (SMHS 2016). Methods: A two-phase design comprising population-level screening of psychotic symptoms using the World Health Organization Composite International Diagnostic Interview version 3.0 psychosis screen followed by clinical reappraisal based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria were used to establish the prevalence. Results: A total of 6,126 respondents completed the first phase of the study, giving a response rate of 69.5%. 5.2% (n = 326) of respondents endorsed at least one symptom in the psychosis screen. After the phase two clinical reappraisal interviews and adjusting for false-negative rate, the corrected prevalence of schizophrenia and other psychotic disorders was 2.3% (95% CI: 2.3-2.3%). The odds of having DSM-IV schizophrenia and other psychotic disorders was significantly higher among those of Malay ethnicity (OR = 3.9, 95% CI 1.4-11.0), and those who were unemployed (OR = 4.3, 95% CI 1.2-15.9). 80.4% of those with a psychotic disorder had consulted a doctor or a mental health professional for their symptoms. Conclusions: Our results indicate that approximately 2.3% of Singapore's community-dwelling adult population had a lifetime diagnosis of schizophrenia and other psychotic disorders. While the treatment gap of the disorder was relatively small, the severe nature of the disorder emphasizes the need for continued outreach and early diagnosis and treatment.

White light emission from Dy3+-doped ZnO + Bi2O3 + BaF2 + B2O3 + TeO2 glasses: Structural and spectroscopic properties.

The ZnO + Bi2O3 + BaF2 + B2O3 + TeO2 (ZnBiBaBFTe) host glass was prepared by melt quenching technique with the aim of achieving white light emission from Dy3+ ions. Their structural and spectroscopic properties were systemically investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Visible absorption, emission spectra and decay times. Judd-Ofelt (JO) parameters (Ωλ) evaluated from absorption spectrum were utilized to calculate the radiative parameters for 4F9/2 level of Dy3+ ions. The optical band gap energy of as-prepared glasses were calculated for the indirect, (αhυ)1/2 and direct, (αhυ)2 allowed transitions. The emission spectra of Dy3+:ZnBiBaBFTe glasses showed two intense peaks at 575 nm (4F9/2→6H13/2) and 481 nm (4F9/26H15/2) upon 386 nm excitation. The highest emission intensity was observed at 1.0 mol% of Dy3+ for 4F9/2→6H13/2 transition and the results are used in conjunction with lifetime measurements to derive spectroscopic parameters for the stimulated emission cross-section (25.2 × 10-22 cm2), gain bandwidth (5.86 × 10-28 cm3), and favourable quantum efficiency (74.2%). Moreover, white light can be realized with a CIE coordinates by adjusting the concentration of Dy3+ ions in ZnBiBaBFTe host glass. Efficient spectroscopic values and realizable white lighting in Dy3+-doped ZnBiBaBFTe glasses may have potential applications in laser illumination devices.

Antiobesity efficacy of asiatic acid: down-regulation of adipogenic and inflammatory processes in high fat diet induced obese rats.

In the current study, we evaluated the effects of Asiatic acid (AA) on lipid metabolic markers in HFD-induced obese Sprague-Dawley rat model. AA (20 mg/kg BW) was administered orally to HFD-fed rats for 42 days. Changes in body composition, glucose, insulin resistance (IR) and lipid profiles of tissues, plasma and the pattern of gene expression of peroxisome proliferator-activated receptor-γ (PPAR-γ) and its target genes fatty-acid synthase (FAS), adipocyte protein-2 (aP2) and uncoupling protein-2 (UCP-2) and pro-inflammatory factor tumor necrosis factor (TNF)-α were observed in experimental rats. Oral administration of AA exerts therapeutic effects similar to orlistat in attenuating body weight gain, glucose, IR, plasma and tissue lipids and mRNA levels of PPAR-γ, FAS, aP2 and inflammatory factor TNF-α and increasing UCP-2 expression in HFD-fed rats. Hence, these findings concluded that AA attenuate HFD-induced obesity by modulating PPAR-γ and its target genes and regulate lipid metabolism, suggesting their possible antiobesity effects.

Trajectories of symptom severity and functioning over a three-year period in a psychosis high-risk sample: A secondary analysis of the Neurapro trial.

The Ultra-High Risk (UHR) for psychosis group is known to be heterogeneous with diverse outcomes. This study aimed to: 1. Identify subclasses of UHR individuals based on trajectories of symptomatic and functional change over time, 2. Identify predictors of these trajectories. A sample of 304 UHR individuals participating in the Neurapro trial were followed over an average of 40 months. All participants received cognitive-behavioural case management (CBCM). Symptomatic and functional profiles were investigated using latent class growth analysis. Multinomial regression was employed to investigate predictors of classes. Identified trajectories showed mostly parallel slopes (i.e. improving symptoms/functioning over time), which were primarily distinct regarding the severity of symptomatology/level of functioning at baseline (i.e. the intercept). Higher symptomatic/lower functioning classes were predicted by higher substance use, older age, female gender, and lower cognitive functioning. No divergent trajectories were identified as all classes improved over time. This may reflect effective treatment through CBCM, natural illness course, or effective engagement with mental health services. Nonetheless, classes highest in symptoms/lowest in functioning still showed considerable impairment during follow-up, highlighting the need for targeted intervention in these subgroups. The study emphasizes the need for more clinical attention directed towards UHR patients being female or using substances.

Indium-catalyzed C-S cross-coupling of aryl halides with thiols.

Indium-catalyzed C-S cross-coupling of aromatic and alkane thiols with aryl halides proceeds smoothly in the presence of In(OTf)(3) (10 mol %), TMEDA (20 mol %), and KOH as a base in DMSO at 135 degrees C. When this protocol was utilized, a variety of thiols could be cross-coupled with aryl halides to afford the corresponding aryl sulfides in good to excellent yields.
