Assessment of treatment retention rates and predictors of retention on opioid agonist treatment among adolescents.

INTRODUCTION: Opioid agonist treatment (OAT) is an effective treatment for opioid dependence syndrome in adults. However, studies on effectiveness of OAT in adolescents are limited; existing studies show varying retention rates. The present study aimed to assess OAT retention rates in adolescent patients with opioid dependence syndrome registered in a community drug treatment clinic in Delhi, India, and to analyse factors associated with retention at 1 year. METHODS: Retrospective cohort study. All adolescents (n = 130) aged 10-19 years, started on OAT from January 2020 to July 2022 were included. Baseline and follow-up data was extracted from online record system maintained at the clinic. OAT retention rates at different timepoints were assessed. Multivariable logistic regression was used to discern factors associated with one-year retention. RESULTS: The participants' mean age was 16.9 (SD 1.4) years. Mean age of starting opioids was 14.9 (SD 2.2) years; 29.5% (n = 38) injected opioids. The 6-, 12-, 18- and 24-month retention rate on OAT was 64.4%, 45.6%, 38.7% and 29% respectively. The retention rates with buprenorphine and methadone were comparable. Multivariate logistic regression showed retention for less than 12 months to be significantly associated with younger age of starting heroin, involvement in illegal activities, absenteeism from school and substance use in family. DISCUSSION AND CONCLUSIONS: The 12-month retention rates on OAT in adolescents is comparable to retention rates in adults. Various factors associated with early age of onset of opioid use are also associated with lower retention rates on OAT.

Pathways to care and barriers in treatment among patients with Dissociative disorders.

INTRODUCTION: Dissociative disorder patients often present with sudden and embarrassing symptoms, and it is difficult for the patient and care giver to understand initially, recognize the need for help and reach for appropriate treatment timely. This can result in high risk of engaging in dangerous behaviors such as self-harm and suicidal acts, impaired global functioning, and poor quality of life. Knowledge about the types of barriers which are there in treatment seeking, can help in planning strategies for their removal and to facilitate the treatment process. METHODS: Cross-sectional study among patients (n=133) with Dissociative disorders which were recruited from January 2023 to June 2023 in a tertiary care hospital. Pathways to care and barriers in treatment for Dissociative disorders were assessed by interviewing patients using semi-structured proforma. The Dissociative Experience Scale and World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0)) were used to assess disease severity and impact of illness on various domains of life respectively. Group comparison was made to assess differences in social- clinical profile of patients choosing different modalities of treatment. RESULTS: 133 patients of Dissociative disorders with mean age 29.6±9.2, showed their first-choice of help seeking from general practitioner/ neurologist (40.6%), traditional faith healers (35.3%), psychiatrist (18.1%) and 5.2% preferred alternative treatments. This trend changed with 2nd and 3rd contact of help seeking with greater preference for psychiatrist in their 2nd (n=45, 33.8%) and 3rd (n=69, 51.8%) contact. The median duration of untreated illness was 56 weeks (IQR 24-182 weeks). Social-clinical profile of patients varied with their choice of treatment, having lower education level (P = 0.013), longer duration of untreated illness (p=0.003), more severity of symptoms (p=0.032) and greater disability scores(p=0.002) in patients whose first treatment choice was traditional faith healers. More than 70% patients faced availability barriers, stigma, unawareness about mental illness and influence of others in treatment of choice as barriers in initiating and continuing treatment. CONCLUSION: Patients with Dissociative disorders seek treatment from a multitude of healthcare providers including traditional faith healers, general physicians, and alternative medicine practitioners before reaching psychiatrist and undergoes various barriers in treatment. There is need to implement necessary measures for sensitization and awareness about Dissociative disorders to prevent prolonged and undue delays in initiation of appropriate management.

Investigation on pollination approaches, reproductive biology and essential oil variation during floral development in German chamomile (Matricaria chamomilla L.).

German chamomile is an important medicinal and aromatic herb known for its blue essential oil. It lacks studies on anthesis, breeding systems and floral development with their impact on the essential oil. Therefore, the study investigated floral development and divided it into six reproductive stages (RS-1 to RS-6). The first four stages (5-6 days long) were identified as the floral enlargement and differentiation, followed by the fifth stage (10 days long) of three anthesis flushes, i.e., anther dehiscence, ray and disc florets' style branches flush. Anther dehiscence started 1-2 days before style branches flushes showed protandry and overlapped later with style branches flushes. Pollen production started from RS-3 and showed maximum viability (89%) at anther dehiscence (RS-5.1). Pollen showed dispersal through the air up to 0.7 m distance. Seed setting in controlled pollination experiments showed that removing disc florets could be successfully used as the emasculation alternate in German chamomile. The maximum essential oil content (0.40%) at the full blossomed floral stage (RS-4 &-5) suggested the right time for capitula harvesting. The findings on reproductive biology and breeding systems would offer several tools and techniques to support future breeding programs for genetic improvement of German chamomile.

ESBL Production Among E. coli and Klebsiella spp. Causing Urinary Tract Infection: A Hospital Based Study.

INTRODUCTION: Increase in extended-spectrum ß-lactamases (ESBL) producing microbes in recent years has led to limitations of treatment options. This study aimed to assess the prevalence of ESBL producing E. coli and Klebsiella spp. at a tertiary hospital in Nepal. METHODS: A total of 2209 non-repetitive mid-stream urine (MSU) samples were collected during the study period (March to September 2014). Identification of the isolates was done by Gram's staining followed by biochemical tests. Antibiotic susceptibility testing was done by modified Kirby-Bauer disc diffusion method and interpretation was done following Clinical and Laboratory Standard Institute (CLSI) guidelines, 2013. ESBL screening among E. coli and Klebsiella spp. isolates were done using ceftriaxone, cefotaxime, ceftazidime and cefpodoxime. The confirmation was done by phenotypic disc diffusion test (combined disc method) using ceftazidime (30µg) and ceftazidime plus clavulanic acid (30/10µg), and cefotaxime (30µg) and cefotaxime plus clavulanic acid (30/10µg) disc as per CLSI guidelines. RESULTS: A total of 451 samples showed significant bacteriuria with 365 (80.9%) E. coli, 17 (3.8%) Klebsiella pneumoniae and 3 (0.7%) Klebsiella oxytoca. Of 451 isolates, 236 (52.3%) were found MDR strains. By combined disk test, 33 (91.7%) E. coli and 3 (8.3%) Klebsiella spp. were found ESBL producers. CONCLUSION: Higher prevalence of ESBL producing E. coli and Klebsiella spp. was observed warranting prompt need of surveillance for effective management of such MDR strains.
