Social Media and Youth Mental Health.

PURPOSE OF REVIEW: We review recent evidence regarding the relationship between the social media (SM) habits, experiences, and the mental health of youth. We examine effects of social media use (SMU) on specific diagnoses including depression and anxiety. The relationship between psychiatric illness, specific SM experiences, and the issue of SM mental health contagion is also explored. RECENT FINDINGS: Youth engagement in SMU has increased dramatically in recent years, concurrent with increases in prevalence of depression and anxiety. The relationship between SMU and mental illness is complex and depends on characteristics of the user (e.g., social comparison and fear of missing out (FOMO) and their SM habits and experiences (e.g., cyberbullying, and sexting,). SM engagement has distinct impacts on anxiety, depression, and suicidality. Growing evidence documents how SM may be a medium for psychiatric contagion. Research findings are largely correlational and dependent on subjective report, limiting their interpretation. The mental health of youth is increasingly tied to their SMU, depending greatly on how youth engage with SM and resultant feedback. Future research must look to establish causality in relationships between SM and mental illness.

Synthesis, characterization, molecular docking, and antimicrobial activities of dinuclear nickel(ii), palladium(ii), and platinum(iv) complexes.

New nickel(ii), palladium(ii), and platinum(iv) complexes were synthesized by reacting the metal ions with benzidinedioxime in a 1 : 1 mole ratio. The CHN elemental analysis, spectroscopic analyses, and powder X-ray diffraction (PXRD) results showed that two Ni(ii) and two Pd(ii) ions coordinated to two benzidinedioxime ligands via the nitrogen atoms of both oxime groups and the two azomethine nitrogen atoms. In the case of the dinuclear platinum(iv) complex, however, each Pt(iv) is coordinated with the two oxygen atoms of the oxime group and the two azomethine nitrogen atoms of the ligand. Both elemental analyses and PXRD indicated that the complex ions of Ni(ii) and Pt(iv) have distorted octahedral geometry, whereas Pd(ii) has a square planar geometry. Molecular docking studies showed that the nickel(ii) complex is the most potent dual DHPS/DHFR bacterial inhibitor. The receptor of the DHPS enzyme (3ZTE) showed the best interaction with the nickel(ii) complex when compared to a receptor of the DHFR enzyme (3FRB). All the synthesized complexes and ligand exhibited significant results against PS. Aeruginous than their corresponding SMX-TMP drug. Among the three synthesized complexes, the nickel(ii) complex possessed the highest antimicrobial activities against tested microorganisms.

In Silico and In Vitro Evaluation of Some Amidine Derivatives as Hit Compounds towards Development of Inhibitors against Coronavirus Diseases.

Coronaviruses, including SARS-CoV-2, SARS-CoV, MERS-CoV and influenza A virus, require the host proteases to mediate viral entry into cells. Rather than targeting the continuously mutating viral proteins, targeting the conserved host-based entry mechanism could offer advantages. Nafamostat and camostat were discovered as covalent inhibitors of TMPRSS2 protease involved in viral entry. To circumvent their limitations, a reversible inhibitor might be required. Considering nafamostat structure and using pentamidine as a starting point, a small set of structurally diverse rigid analogues were designed and evaluated in silico to guide selection of compounds to be prepared for biological evaluation. Based on the results of in silico study, six compounds were prepared and evaluated in vitro. At the enzyme level, compounds 10-12 triggered potential TMPRSS2 inhibition with low micromolar IC50 concentrations, but they were less effective in cellular assays. Meanwhile, compound 14 did not trigger potential TMPRSS2 inhibition at the enzyme level, but it showed potential cellular activity regarding inhibition of membrane fusion with a low micromolar IC50 value of 10.87 µM, suggesting its action could be mediated by another molecular target. Furthermore, in vitro evaluation showed that compound 14 inhibited pseudovirus entry as well as thrombin and factor Xa. Together, this study presents compound 14 as a hit compound that might serve as a starting point for developing potential viral entry inhibitors with possible application against coronaviruses.

A detailed multi-omics analysis of GNB2 gene in human cancers.

The Guanine-nucleotide binding protein 2 (GNB2) encodes for ß2 subunit (Gß2) of the G-protein complex. Keeping in view the increased demand of reliable biomarkers in cancer, the current study was planned to extensively explored GNB2 expression variation and its roles in different cancers using online available databases and diverse methodology. In view of our results, the GNB2 was notably up-regulated relative to corresponding controls in twenty three cancer types. As well, the elevated expression of GNB2 was found to be associated with the reduced overall survival (OS) of the Liver Hepatocellular Carcinoma (LIHC) and Rectum Adenocarcinoma (READ) only out of all analyzed cancer types. This implies GNB2 plays vital role in the tumorigenesis of LIHC and READ. Several additional analysis also explored six critical pathways and few important correlations related to GNB2 expression and different other parameters such as promoter methylation, tumor purity, CD8+ T immune cells infiltration, and genetic alteration, and chemotherapeutic drugs. In conclusion, GNB2 gene has been identified in this study as a shared potential biomarker (diagnostic and prognostic) of LIHC and READ.

An exploratory study of clinical and physiological correlates of problematic social media use in adolescents.

Prior validation studies of the Bergen Social Media Addiction Scale (BSMAS) demonstrate its utility for identifying problematic social media use in adolescents. There are knowledge gaps regarding the potential clinical and physiological underpinnings of problematic social media use in adolescents. This cross-sectional, single-visit study examined a sample of depressed (n = 30) and healthy (n = 30) adolescents who underwent clinical assessments of depressive symptom severity, bullying, cyberbullying, self-esteem, salivary measures of stress (cortisol and α-amylase) to identify correlates with adolescent and parental reports of the BSMAS. LASSO-penalized multiple linear regression models were implemented. With respect to the adolescent BSMAS scores in all subjects, the risk of problematic social media increased as depressive symptom severity increased. Depressed female adolescents appeared to have a greater risk. Based on parental BSMAS scores, depression status, depressive symptom severity, cyberbullying score, and salivary cortisol significantly predicted problematic social media use. For the depressed sample, the risk of problematic social media use increased as salivary cortisol increased. No significant predictors of problematic social media usage emerged in the healthy control sample. These preliminary results provide novel insights into clinical and physiological characteristics of problematic social media use in adolescents.

A Retrospective Evaluation of a Pilot Youth Community Assessment and Treatment Service.

OBJECTIVE: Targeted, highly accessible early intervention for youths with emerging and complex psychiatric presentations is increasingly needed. The Youth Community Assessment and Treatment Team (YCATT) multidisciplinary service was established to provide intensive intervention for youths in Perth, Australia. METHODS: The authors conducted a retrospective evaluation to examine YCATT's impact on emergency department (ED) visits, psychiatric inpatient admissions, and provision of care for youths in the transition period between adolescent and adult psychiatric services. Demographic, clinical, and service utilization data for all referrals over the pilot period (2016-2017) were collected and analyzed with descriptive statistics. RESULTS: During the pilot period, 308 referrals were accepted. All referred youths had a trauma history and presented with acute or complex conditions, and most (66%) were between 16 and 18 years old. The admission rate to a psychiatric inpatient unit was <7%. Of 61 youths specifically referred to YCATT as an alternative to psychiatric admission, 90% were successfully diverted from psychiatric or ED admission. After discharge from YCATT, youths had improved scores on the Health of the Nations Outcome Scale and 10-item Kessler Psychological Distress Scale. CONCLUSIONS: These findings suggest that YCATT is an accessible and effective service for the population of transition-age youths. It appears that YCATT, in collaboration with other community services, contributed to diverting psychiatric inpatient admissions, facilitated outpatient treatment, and enabled continuity of care for vulnerable youths. The results underscore the need for more accessible, individualized treatment approaches for youths who transition to adulthood.

Altered markers of stress in depressed adolescents after acute social media use.

Social media use (SMU) is an inherent element in the daily life and neurodevelopment of adolescents, but broad concerns exist regarding the untoward effects of social media on adolescents. We conducted a prospective, cross-sectional study that sought to examine the acute effects of SMU on clinical measures and biomarkers of stress in healthy and depressed adolescents. After at least 24 h of abstinence from social media, depressed adolescents (n = 30) and healthy control adolescents (n = 30) underwent baseline clinical assessment of their prior SMU, depressive symptom severity, self-esteem, and exposure to bullying. Participants provided salivary samples that were analyzed for α-amylase and cortisol levels. After 20 min of unsupervised SMU, saliva analyses and clinical assessments were repeated. After 20 min of SMU, salivary cortisol and α-amylase levels were significantly higher in adolescents with depression but not in healthy control adolescents. Furthermore, small but statistically significant changes in depressive symptom severity occurred in all participants. These changes in depressive symptoms were not clinically meaningful. SMU did not significantly change self-esteem measures among participants. Adolescents with depression appeared to have more physiological reactivity after SMU compared with healthy adolescents. Further research should characterize SMU as a clinical dimension and risk factor among adolescents with depression and other psychiatric disorders.

Suicidality and self-injurious behavior among adolescent social media users at psychiatric hospitalization.

BACKGROUND: The current study sought to examine the relationship between documented social media use and suicidality and self-injurious behaviors in adolescents at the time of psychiatric hospitalization. METHODS: We retrospectively identified adolescents (aged 12-17 years) hospitalized on an inpatient psychiatric unit during 1 year. Abstracted information included documented social media use, demographic variables, documented self-injurious behaviors, the Patient Health Questionnaire-9, and the Suicide Status Form-II. Logistic regression was implemented to examine the effect of social media use on the risk of self-injurious behaviors and suicidality. RESULTS: Fifty-six adolescents who used social media were identified and matched with 56 non-social media users. Those with reported social media use had significantly greater odds of self-injurious behaviors at admission (odds ratio, 2.55; 95% confidence intervals, 1.17-5.71; P = .02) vs youth without reported social media use. Adolescents with reported social media use also had greater odds of increased suicidal ideation and suicide risk than those with no reported use, but these relationships were not statistically significant. CONCLUSIONS: Social media use in adolescents with a psychiatric admission may be associated with the risk of self-injurious behaviors and could be a marker of impulsivity. Further work should guide the assessment of social media use as part of a routine adolescent psychiatric history.

Evidence Based Dyadic Therapies for 0- to 5-Year-Old Children With Emotional and Behavioral Difficulties.

As many as one in four preschool-aged children are estimated to struggle with psychosocial stress and social-emotional issues; yet, interventions are often postponed until older ages when change is actually more difficult. Reasons for this include limited interventions, paucity of FDA approved medications for young children, as well as the dearth of clinicians adequately trained in psychotherapeutic approaches for young children. This commentary outlines indications of the four most commonly used evidence-based dyadic psychotherapies for young children: Child-Parent Psychotherapy (CPP) and Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), used primarily for young children with trauma, and Parent-Child Interaction Therapy (PCIT) and Child Parent Relationship Therapy (CPRT), used mostly for children with behavioral issues. Rooted in attachment theory and further supported by the premise that the quality of the child-caregiver dyad is paramount to psychological wellbeing, these therapies focus on strengthening this relationship. Literature indicates that insecure or disorganized early attachments adversely affect an individual's lifelong trajectory. These therapies have demonstrated efficacy leading to positive behavioral changes and improved parent-child interactions. The major challenges of clinical practice focused on young children and their families include proper diagnosis and determining the best therapeutic strategy, especially for families who have not benefited from prior interventions. At this time, it is still unclear which therapy is best indicated for which type of patients and it mostly has been driven by convenience and provider preference or training. Further research is required to tailor treatments more successfully to the child's needs.

The Differential Impact of Social Media Use on Middle and High School Students: A Retrospective Study.

Background: Social media use is now a central aspect of adolescent life and development. Little is known about the clinical implications of social media use in children and adolescents presenting in acute crisis for psychiatric admission. This study sought to compare the potential effects of social media use among middle and high school students on outcomes of psychiatric morbidity. It was hypothesized that among social media users, high school students would have greater psychiatric morbidity compared with middle school students. Methods: The research team extracted clinical and demographic data from adolescents (aged 12-17 years) presenting for acute psychiatric admission who also had documented social media use (N = 56). Educational status, middle school (n = 21) versus high school (n = 35), was examined as an independent variable. Psychotropic medication use, self-injurious behavior, suicide risk, and suicidal ideation were examined as dependent variables in logistic regression models. Results: High school students using social media had significantly greater predicted odds of psychotropic medication use and self-injurious behavior compared with students in middle school who used social media. High school students using social media had greater, although not statistically significant, predicted odds of suicide risk and suicidal ideation compared with middle school students using social media. Conclusions: Social media use is likely an important factor to consider in psychiatric evaluations. The present findings suggest that social media use in high school students is associated with greater psychiatric morbidity compared with middle school students. Further research could illuminate the developmental lines of social media use and age-specific risks.

Decreasing Treatment Duration of Electroconvulsive Therapy (ECT) Using Daily Right Unilateral Ultrabrief Instead of Bitemporal ECT.

OBJECTIVE: Electroconvulsive therapy (ECT) is an effective treatment for depression, but the standard 2 to 3 times weekly treatment course results in a total treatment duration of >2 weeks. We explored the viability of decreasing treatment duration by using daily right unilateral ultrabrief (RULUB) ECT instead of standard bitemporal (BT) ECT. METHODS: This study involved a retrospective review of records of inpatients 18 to 64 years of age who were treated between 2012 and 2017 at a large tertiary ECT center. Lead placement/technique, treatment duration (days from first to last ECT), number of ECT treatments, and scores on the Patient Health Questionnaire-9 (PHQ-9), and the Hamilton Depression Rating Scale (HamD-24) were collected. Statistical analysis was performed using 1-way analysis of variance and t tests. RESULTS: Of 214 patients, 112 started daily RULUB ECT (86 were completers and 26 were eventually switched to BT), and 83 started and completed BT ECT. Daily RULUB completers finished their course of ECT 6.5 days faster than those who received BT ECT (11.7 vs. 18.2 d, P<0.0001), while the number of ECT treatments did not significantly differ between the 2 groups (daily RULUB 8.6 treatments vs. BT 8.3 treatments, P=0.4402). There were no significant differences in the final PHQ-9 or HamD-24 depression scores between the 2 groups. One case of significant cognitive impairment was observed in the daily RULUB group. CONCLUSIONS: Daily RULUB ECT compared with BT ECT allowed depression to be treated faster and with similar efficacy. Randomized controlled trials, which include the use of formal cognitive and physical side effect measures, are needed to further explore the viability of daily RULUB ECT.

Parent-Child Interaction Therapy in a Case of Global Developmental Delay and Leukoencephalopathy.

Parent-child interaction therapy (PCIT) is an evidence-based, behavioral dyadic treatment for caregivers and their children aged 2-7 years old with emotional and behavioral disorders. Here we present a treatment course of a 3-years-old girl with leukoencephalopathy, dysgenesis of the brainstem, and associated global developmental delay who was diagnosed with muscular dystrophy after PCIT completion. At the beginning of PCIT she had the developmental level of an 18 months old with language skills of a 12-18 months old; both her vocabulary and verbal expression were very limited. She had slow, unco-ordinated gait with limited fine motor skills. She was referred to Psychiatry with concerns regarding disruptive behaviors including severe self-injury. PCIT was started with a focus on PRIDE skills (Praise, Reflection, Imitation, behavioral Description and Enjoyment); particularly behavioral description and reflection with simple developmentally appropriate labeled praise. Modifications to treatment included using non-verbal actions (e.g., "high fives" as praises), sign language and using only one-step basic commands, which greatly improved compliance. In a matter of weeks, the patient demonstrated remarkable improvement in her disruptive behavior as evidenced by parent/daycare report and clinical observation. Surprisingly her vocabulary more than doubled and her ability of self-expression also increased; she was able to point to things and ask for them. This clinical experience suggests that PCIT principles are effective treatment interventions for other clinical presentations outside of the usual inclusion criteria. Implementation of targeted PCIT interventions greatly benefited the development of language skills and communication in a young child with global developmental delay.

Dementia Care at End of Life: Current Approaches.

PURPOSE OF REVIEW: Dementia is a progressive and life-limiting condition that can be described in three stages: early, middle, and late. This article reviews current literature on late-stage dementia. RECENT FINDINGS: Survival times may vary across dementia subtypes. Yet, the overall trajectory is characterized by progressive decline until death. Ideally, as people with dementia approach the end of life, care should focus on comfort, dignity, and quality of life. However, barriers prevent optimal end-of-life care in the final stages of dementia. Improved and earlier advanced care planning for persons with dementia and their caregivers can help delineate goals of care and prepare for the inevitable complications of end-stage dementia. This allows for timely access to palliative and hospice care, which ultimately improves dementia end-of-life care.

Urethral Polyembolokoilamania: An Unusual Manifestation of Behavioral and Psychological Symptoms of Dementia (BPSD).

Behavioral and psychological symptoms of dementia (BPSD) have varied presentations and frequently occur throughout the trajectory of dementia. Hypersexuality and general disinhibition of societal and cultural norms are commonly documented in all types of dementia. However, sparse literature exists on polyembolokoilamania (insertion of foreign objects in bodily orifices) without a sexual component as a dementia-related symptom. We review an unusual case of a 94-year-old man who presented with urethral polyembolokoilamania without hypersexuality or other behavioral disinhibition. We highlight clinical considerations of managing urethral polyembolokoilamania in an elderly patient without a previous neurocognitive disorder diagnosis. A multidisciplinary team approach with input from Internal Medicine, Urology, Psychiatry, and Neurology lead to a comprehensive assessment of a patient that could have been managed solely as a surgical case. This spearheaded a formal diagnosis of neurocognitive disorder-guiding successful management, follow-up, caregiver education, and reduction of further harm.

SiglecF+Gr1hi eosinophils are a distinct subpopulation within the lungs of allergen-challenged mice.

Although eosinophils as a group are readily identified by their unique morphology and staining properties, flow cytometry provides an important means for identification of subgroups based on differential expression of distinct surface Ags. Here, we characterize an eosinophil subpopulation defined by high levels of expression of the neutrophil Ag Gr1 (CD45+CD11c-SiglecF+Gr1hi). SiglecF+Gr1hi eosinophils, distinct from the canonical SiglecF+Gr1- eosinophil population, were detected in allergen-challenged wild-type and granule protein-deficient (EPX-/- and MBP-1-/-) mice, but not in the eosinophil-deficient ΔdblGATA strain. In contrast to Gr1+ neutrophils, which express both cross-reacting Ags Ly6C and Ly6G, SiglecF+Gr1hi eosinophils from allergen-challenged lung tissue are uniquely Ly6G+ Although indistinguishable from the more-numerous SiglecF+Gr1- eosinophils under light microscopy, FACS-isolated populations revealed prominent differences in cytokine contents. The lymphocyte-targeting cytokines CXCL13 and IL-27 were identified only in the SiglecF+Gr1hi eosinophil population (at 3.9 and 4.8 pg/106 cells, respectively), as was the prominent proinflammatory mediator IL-13 (72 pg/106 cells). Interestingly, bone marrow-derived (SiglecF+), cultured eosinophils include a more substantial Gr1+ subpopulation (∼50%); Gr1+ bmEos includes primarily a single Ly6C+ and a smaller, double-positive (Ly6C+Ly6G+) population. Taken together, our findings characterize a distinct SiglecF+Gr1hi eosinophil subset in lungs of allergen-challenged, wild-type and granule protein-deficient mice. SiglecF+Gr1hi eosinophils from wild-type mice maintain a distinct subset of cytokines, including those active on B and T lymphocytes. These cytokines may facilitate eosinophil-mediated immunomodulatory responses in the allergen-challenged lung as well as in other distinct microenvironments.
