ABSTRACT

INTRODUCTION: Caregivers of patients with primary malignant brain tumours experience substantial psychological distress while caring for someone with a progressive, life-limiting neurological illness. However, there are few interventions aimed at addressing the psychosocial needs of this population. We developed and are testing a population-specific, evidence-based, telehealth intervention (NeuroCARE) to reduce anxiety symptoms and improve psychosocial functioning in this caregiver population. METHODS AND ANALYSIS: This study is a non-blinded, randomised controlled trial of a psychological intervention for caregivers of patients with primary malignant brain tumours receiving care at the Massachusetts General Hospital Cancer Center or Dana-Farber Cancer Institute. We will enrol 120 caregivers who screen positive for heightened anxiety. Participants will be randomised 1:1 to the NeuroCARE intervention or a usual care control condition. Caregivers assigned to NeuroCARE will complete six individual telehealth sessions with a trained behavioural health specialist over 12 weeks. Caregivers randomised to the control condition will receive usual care, including possible referral to social work or other appropriate resources. Participants will complete self-report questionnaires at baseline and 11 weeks and 16 weeks postrandomisation. The primary outcome is anxiety symptoms at 11 weeks among NeuroCARE participants, compared with usual care. Secondary outcomes include caregiver-reported depressive symptoms, quality of life, caregiver burden, caregiving self-efficacy, perceived coping skills and post-traumatic stress disorder symptoms. We also will explore potential mediators of the NeuroCARE effect on caregiver anxiety symptoms. ETHICS AND DISSEMINATION: The study is funded by a Career Development Award from Conquer Cancer, the American Society of Clinical Oncology Foundation (award number 2019CDA-7743456038) and approved by the Dana-Farber/Harvard Cancer Center Institutional Review Board (Protocol #19-250 V.10.1). The study will be reported in accordance with the Consolidated Standards of Reporting Trials statement for non-pharmacological trials. Results will be presented at scientific meetings and in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04109209.

ABSTRACT

Context: Neisseria gonorrhoeae is a Gram-negative diplococcus, an obligate human pathogen, and the etiologic agent of the sexually transmitted infection (STI), gonorrhoea. culture is the standard procedure for diagnosis, which may be supported by nucleic acid tests and microscopy. Aims: To determine the best possible method of diagnosis for Gonococcus infection in resource-limited settings. Settings and Design: The meta-analyses were designed to determine the difference in diagnosis between Culture and nucleic acid amplification tests (NAATs) and also between the different Amplification Tests and widely available Roche COBAS AMPLICOR test. Subjects and Methods: Databases searched were Pubmed, Medline, Google Scholar and Cochrane reviews. Risk ratio (RR) with 95% confidence intervals was estimated for the dichotomous outcomes. The random-effect model was applied for all the studies in the analysis. Statistical Analysis Used: The meta-analysis was computed in RevMan Version 5.3, Copenhagen, Denmark. Results: In the first analysis, NAATs significantly improved the chances of detection in comparison to the standard culture and final RR was 1.24 (1.05-2.51), which put the diamond on the right of no-effect axis, indicating more positives by NAATs. In the second analysis, AMPLICOR had the more positive results, which may have indicated better detection rate, as well as less specificity and final RR was 0.809 (0.737-0.888), which put the diamond on the left of the non-effect axis, indicating more positives by AMPLICOR. Conclusions: In a resource-limited scenario like India, the syndromic management of STIs are considered to be the norm. A positive diagnosis is only given if the tests are confirmed by Culture, as it is still considered to be the gold standard of diagnosis. However, in many cases, due to suboptimal transportation and lack of proper handling, culture in unable to grow even if the patient is infected. In such cases, Nucleic Acid Tests should be able to detect an infection.

ABSTRACT

For last few years in the early spring bird flu poses a threat to India. The causative agent H5N1 virus is also getting robust day by day acquiring an ability to cross the species barrier. It is now known as (H5N1) which is emerging as killer virus to man. Although human casualty is yet to be recorded from India, but the threat is not over. The present study had been undertaken in the village of Hakimpur of Singur Block of District Hooghly, West Bengal, with a population 862 of 215 families. The objective of the study was to assess the knowledge of the study population regarding bird flu and to study their practice regarding poultry maintenance. The head of the family from each family was interviewed. A house to house survey in the census method on a pre-designed, pre-tested, semi-structured schedule was done. Information regarding socio-demographic profile, poultry keeping, correct knowledge about bird flu, mode of transmission, culling, etc was recorded. The data were collected and analyzed by relevant statistical methods. The results showed that 46% respondents knew what bird flu is, 62.8% knew the mode of transmission, and 35.3% knew the procedure of culling. Out of literates about 53% and out of the illiterates only 0.93% were aware of the transmission of the virus through body fluids. The predominant source of information was mass media. 57.14% of the families rearing poultry, kept the birds in shed, 40.48% in cage, and 2.38% in living room.

ABSTRACT

The Tetrahymena thermophila origin recognition complex (ORC) contains an integral RNA subunit, 26T RNA, which confers specificity to the amplified ribosomal DNA (rDNA) origin by base pairing with an essential cis-acting replication determinant--the type I element. Using a plasmid maintenance assay, we identified a 6.7 kb non-rDNA fragment containing two closely associated replicators, ARS1-A (0.8 kb) and ARS1-B (1.2 kb). Both replicators lack type I elements and hence complementarity to 26T RNA, suggesting that ORC is recruited to these sites by an RNA-independent mechanism. Consistent with this prediction, although ORC associated exclusively with origin sequences in the 21 kb rDNA minichromosome, the interaction between ORC and the non-rDNA ARS1 chromosome changed across the cell cycle. In G(2) phase, ORC bound to all tested sequences in a 60 kb interval spanning ARS1-A/B. Remarkably, ORC and Mcm6 associated with just the ARS1-A replicator in G(1) phase when pre-replicative complexes assemble. We propose that ORC is stochastically deposited onto newly replicated non-rDNA chromosomes and subsequently targeted to preferred initiation sites prior to the next S phase.
