Declining tuberculosis prevalence in Saharia, a particularly vulnerable tribal community in Central India: evidences for action.

BACKGROUND: In spite of an alarmingly high tuberculosis (TB) burden amongst the Saharia tribe of central India, there is hardly any study to investigate the impact of DOTS implementation on the magnitude of tuberculosis disease and the changes over time. This article present the findings of TB prevalence surveys conducted amongst this indigenous population in two different time periods to know the change in the prevalence of TB. METHODS: A cross sectional survey was conducted among Saharia population in Shivpuri district, Madhya Pradesh during February 2013 to May 2013 and resurvey during March 2015 to July 2015. All individuals (≥15 years) were examined for chest symptoms suggestive of TB. Sputum samples were collected from all presumptive TB cases and were confirmed by laboratory examination by Ziehl-Neelsen smear microscopy and solid media culture methods. All detected cases were referred to health facility for anti-tuberculosis treatment as per RNTCP guidelines. RESULTS: There was significant reduction (trend Chi square 19.97; OR = 1.521; p = 0.000) in the prevalence of TB at the endline (1995 per 100,000) as compared to baseline (3003 per 100,000). The reduction was significant among males as compared to females (OR 1.55; p = 0.000) and in the age group of 25-34 years (OR 2.0; p = 0.007) and 45-54 years (OR 4.39; p = 0.003). There was significant reduction in the prevalence in both smear (OR 1.29; p = 0.02) and culture positive (OR 1.57; p = 0.000) TB at the endline survey. CONCLUSION: The study findings highlight a reduction in the prevalence of TB among Saharia tribal population. Further studies are needed to identify the factors associated with reduction in prevalence among this population and also further surveys to monitor the prevalence trend over a period.

Stochastics of Cellular Differentiation Explained by Epigenetics: The Case of T-Cell Differentiation and Functional Plasticity.

Epigenetic marks including histone modifications and DNA methylation are associated with the regulation of gene expression and activity. In addition, an increasing number of non-coding RNAs with regulatory activity on gene expression have been identified. Alongside, technological advancements allow for the analysis of these mechanisms with high resolution up to the single-cell level. For instance, the assay for transposase-accessible chromatin using sequencing (ATAC-seq) simultaneously probes for chromatin accessibility and nucleosome positioning. Thus, it provides information on two levels of epigenetic regulation. Development and differentiation of T cells into functional subset cells including memory T cells are dynamic processes driven by environmental signals. Here, we briefly review the current knowledge of how epigenetic regulation contributes to subset specification, differentiation and memory development in T cells. Specifically, we focus on epigenetic mechanisms differentially active in the two distinct T cell populations expressing αß or γδ T cell receptors. We also discuss examples of epigenetic alterations of T cells in autoimmune diseases. DNA methylation and histone acetylation are subject to modification by several classes of 'epigenetic modifiers', some of which are in clinical use or in preclinical development. Therefore, we address the impact of some epigenetic modifiers on T-cell activation and differentiation, and discuss possible synergies with T cell-based immunotherapeutic strategies.

Families of Diaporthales based on morphological and phylogenetic evidence.

Diaporthales is an important ascomycetous order comprising phytopathogenic, saprobic, and endophytic fungi, but interfamilial taxonomic relationships are still ambiguous. Despite its cosmopolitan distribution and high diversity with distinctive morphologies, this order has received relativelyiaceae, Macrohilaceae, Melanconidaceae, Pseudoplagiostomaceae, Schizoparmaceae, Stilbosporaceae and Sydowiellaceae. Taxonomic uncertainties among genera are also clarified and recurrent discrepancies in the taxonomic position of families within the Diaporthales are discussed. An updated outline and key to families and genera of the order is presented.

An analysis of the fate of 917 manuscripts rejected from Clinical Otolaryngology.

OBJECTIVES: The fate of all manuscripts rejected from the journal Clinical Otolaryngology (CO) over a three-year period was investigated. The aim was to review publication rate, delay and the impact factors of the journals that the papers went on to be published in. DESIGN: In total, 917 papers were rejected from CO between 2011 and 2013. The fate of these manuscripts was determined by searching for the corresponding author's surname, and if necessary keywords from the manuscript title, in both PubMed and Google Scholar. MAIN OUTCOME MEASURES: The main outcome measures recorded were as follows: the subsequent publication of the article, delay to publication and journal of publication. RESULTS: In all, 511 papers were subsequently published in journals, representing 55.7% of all rejected manuscripts. The average delay was 15.1 months (standard deviation [sd] = 8.8). The impact factor of CO was found to be higher than the average of the journals that accepted the rejected manuscripts in all 3 years. Only 41 (8%) papers were published in journals with a higher impact factor than CO. Of all subsequently accepted manuscripts, 60 (11.7%) were found only on Google Scholar (and not on PubMed). CONCLUSIONS: Rejection from CO certainly does not prevent subsequent publication, although the papers tend to be published after a lengthy delay and in journals with a lower impact factor than CO. When performing literature searches, it is important to search more than one database to ensure as many of the relevant articles are found as possible.

A re-appraisal of publication rates of scientific papers presented at the Otorhinolaryngology Research Society meetings.

OBJECTIVES: To review the rate of publication of papers in peer-reviewed journals after oral presentations at the Otorhinolaryngology Research Society meetings between 1996 and 2013 and to compare trends with the previous review (1979-1995). DESIGN: Literature review. SETTING: Merseyside ENT Research Collaborative. PARTICIPANTS: The abstracts of presentations at Otorhinolaryngology Research Society meetings are published in Clinical Otolaryngology. A structured search of PubMed was undertaken to identify published Otorhinolaryngology Research Society presentations. MAIN OUTCOME MEASURES: Publication rates. RESULTS: A total of 460 abstracts were identified. The interobserver reliability among reviewers was 98%. Of the total, 259 (56.3%) abstracts were published in peer-reviewed journals. The average time from Otorhinolaryngology Research Society presentation to publication was 27.7 months (median 23), which was not significantly different from the previous review. Publication by subspeciality was as follows: head and neck (45.6%), otology (30.5%), rhinology (22%) and others (1.9%). Most published Otorhinolaryngology Research Society presentations were published in Clinical Otolaryngology (22.4%), followed by the Journal of Laryngology and Otology (8.1%) and the Laryngoscope (7.3%). Clinical research was the most common category of abstracts being presented at Otorhinolaryngology Research Society meetings, followed by laboratory-based research. Over half (56.5%) of laboratory research presented were head and neck themed, while otology and rhinology predominated clinical research presentations. Over half (52.1%) of Otorhinolaryngology Research Society abstracts originated from units in the North of England. Bristol presented the most abstracts (30.1%), followed by Newcastle (25.1%). CONCLUSIONS: The publication rate of Otorhinolaryngology Research Society presentations remains high and many are subsequently published in high-impact factor otolaryngology journals. More Otorhinolaryngology Research Society presentations are now published in American and European journals.

Performance of Revised National Tuberculosis Control Programme (RNTCP) in tribal areas in India.

BACKGROUND & OBJECTIVES: The Revised National Tuberculosis Control Programme (RNTCP) provides free diagnostic and treatment services to all tuberculosis (TB) patients registered under it. Equitable access, implying a preference for the most hard-to-reach groups particularly for tribal areas, is a major concern for RNTCP. This study was conducted to assess the performance of RNTCP in terms of case detection and cure rates in areas dominated by tribal groups in India. METHODS: We used the RNTCP data collected by the Central TB Divison, Government of India. RNTCP has a systematic monitoring mechanism which tracks the outcome of every patient put on treatment. There is a standardized recording and reporting structure in place; indicators are monitored regularly at every level of the health system; and regular supervision ensures quality of the Programme. The main indicators include the number of cases diagnosed and the percentage of patients who are successfully treated. These indicators were used to assess the RNTCP performance in tribal areas. RESULTS: We observed a poor performance in terms of case detection rate (CDR) in tribal and backward districts as compared with other districts in India. Among tribal districts 53 per cent in 2010, 45 per cent in 2011 and 56 per cent in 2012 had CDR of new smear positive <70%. It was also observed that 26 per cent of tribal dominated districts had CDR of <51 per cent in 2012. More than 50 per cent of tribal districts were not able to achieve more than 85 per cent of cure rate. INTERPRETATION & CONCLUSIONS: The findings of this study suggested that the overall RNTCP performance in tribal areas was not optimal, and the target of >85 per cent of core rate was achieved by less than half of the tribal districts.

Pulmonary tuberculosis - a health problem amongst Saharia tribe in Madhya Pradesh.

BACKGROUND & OBJECTIVES: The information on tuberculosis (TB) situation amongst Saharia, one of the particularly vulnerable tribal groups (PVTGs) in Madhya Pradesh, is not available from Gwalior division of the s0 tate. Hence, this study was undertaken to estimate the prevalence of pulmonary tuberculosis (PTB) disease amongst them. METHODS: A community based cross-sectional TB prevalence survey was undertaken among Saharia PVTG in Gwalior district of Madhya Pradesh. A random sample of villages predominated by Saharia tribe was selected from all the blocks in proportion to the size of Saharia population in each block of the district. All eligible individuals were questioned for chest symptoms relating to TB. Two sputum samples were collected from each of the eligible individuals, transported to the laboratory, and were examined by Ziehl-Neelsen(ZN) smear microscopy and solid media culture methods. RESULTS: Of the total 10,259 individuals eligible for screening, 9,653 (94.1%) were screened for symptoms. Overall prevalence of PTB was found to be 3294 per 100,000. The prevalence increased with age and the trend was significant ( p<0.001). The prevalence of TB was significantly higher amongst males (5497/100,000) as compared to females (1376/100,000) ( p<0.001). INTERPRETATION & CONCLUSIONS: The study results provide vital information on the current situation of pulmonary TB disease among the Saharia tribal community in Gwalior district of Madhya Pradesh. In view of high PTB disease prevalence among this PVTG, there is an urgent need to improve and further intensify TB control measures in this area.

Situation of drug resistant tuberculosis in Saharia tribe of central India.

BACKGROUND & OBJECTIVES: The information on multidrug resistant tuberculosis (MDR-TB) situation amongst Saharia, one of the Particularly Vulnerable Tribal Groups (PVTGs) in Madhya Pradesh, India, is not available. Hence, this study was undertaken to find the situation of MDR-TB amongst Saharia PVTG in two districts of Madhya Pradesh. METHODS: Community based cross-sectional TB prevalence surveys were conducted among Saharia PVTG in Gwalior and Shivpuri districts of Madhya Pradesh. Chest symptomatics were identified from the individual registered for the study. Two sputum samples were collected from each of the eligible individuals, transported to the laboratory, and were examined by Ziehl-Neelsen (Z-N) smear microscopy and solid medium culture methods. Drug susceptibility testing of the isolates was done by indirect proportion method on solid medium. RESULTS: MDR rate was 2.2 per cent of new cases and 8.2 per cent among the previously treated cases of TB in Gwalior while it was two per cent among the previously treated cases in Shivpuri district. INTERPRETATION & CONCLUSIONS: Though the prevalence of tuberculosis in these districts was alarmingly high, the MDR rates were more or less similar to national average. However, the findings of this study highlight the need for active intervention so that the MDR-TB is kept under control.

Health literacy on tuberculosis amongst vulnerable segment of population: special reference to Saharia tribe in central India.

BACKGROUND & OBJECTIVES: Health literacy on tuberculosis (TB) is an understanding about TB to perform activities with regard to prevention, diagnosis and treatment. We undertook a study to assess the health literacy on TB among one of the vulnerable tribal groups (Saharia) in central India. METHODS: In this cross-sectional study, 2721 individuals aged >15 yr from two districts of Madhya Pradesh State of India were interviewed at their residence during December 2012-July 2013. By using a short-form questionnaire, health literacy on cause, symptoms, mode of transmission, diagnosis, treatment and prevention of TB was assessed. RESULTS: Of the 2721 (Gwalior 1381; Shivpuri 1340) individuals interviewed; 76 per cent were aged <45 yr. Living condition was very poor (62% living in huts/katcha houses, 84 per cent with single room, 89 per cent no separate kitchen, 97 per cent used wood/crop as a fuel). Overall literacy rate was 19 per cent, and 22 per cent had >7 members in a house. Of the 2721 respondents participated, 52 per cent had never heard of TB; among them 8 per cent mentioned cough as a symptom, 64 per cent mentioned coughing up blood, and 91 per cent knew that TB diagnosis, and treatment facilities were available in both government and private hospitals. Health literacy score among participants who had heard of TB was <40 per cent among 36 per cent of respondents, 41-60 per cent among 54 per cent and >60 per cent among 8 per cent of respondents. INTERPRETATION & CONCLUSIONS: The finding that nearly half of the respondents had not heard of TB indicated an important gap in education regarding TB in this vulnerable population. There is an urgent need to implement targeted interventions to educate this group for better TB control.

Perspectives of Indian traditional and allopathic professionals on religion/spirituality and its role in medicine: basis for developing an integrative medicine program.

Allopathic medical professionals in developed nations have started to collaborate with traditional, complementary, and alternative medicine (TCAM) to enquire on the role of religion/spirituality (r/s) in patient care. There is scant evidence of such movement in the Indian medical community. We aim to understand the perspectives of Indian TCAM and allopathic professionals on the influence of r/s in health. Using RSMPP (Religion, Spirituality and Medicine, Physician Perspectives) questionnaire, a cross-sectional survey was conducted at seven (five TCAM and two allopathic) pre-selected tertiary care medical institutes in India. Findings of TCAM and allopathic groups were compared. Majority in both groups (75% of TCAM and 84.6% of allopathic practitioners) believed that patients' spiritual focus increases with illness. Up to 58% of TCAM and allopathic respondents report patients receiving support from their religious communities; 87% of TCAM and 73% of allopaths believed spiritual healing to be beneficial and complementary to allopathic medical care. Only 11% of allopaths, as against 40% of TCAM, had reportedly received 'formal' training in r/s. Both TCAM (81.8%) and allopathic (63.7%) professionals agree that spirituality as an academic subject merits inclusion in health education programs (p = 0.0003). Inclusion of spirituality in the health care system is a need for Indian medical professionals as well as their patients, and it could form the basis for integrating TCAM and allopathic medical systems in India.

Indian health care professionals' attitude towards spiritual healing and its role in alleviating stigma of psychiatric services.

Persons with mental illnesses in India and rest of developing world continue to consult religious/spiritual (R/S) healers or traditional, complementary and alternative medicine (TCAM) professionals prior to seeking psychiatric services that are devoid of spiritual components of care. We aim to understand TCAM and allopathic professionals' perspectives on patients' R/S needs within mental health services, cross-sectional study was conducted at five TCAM and two allopathic tertiary care hospitals in three different Indian states; 393 participants completed RSMPP, a self-administered, semi-structured survey questionnaire. Perspectives of TCAM and allopathic health professionals on role of spirituality in mental health care were compared. Substantial percentage, 43.7 % TCAM and 41.3 % allopathic, of participants believe that their patients approach R/S or TCAM practitioners for severe mental illness; 91.2 % of TCAM and 69.7 % of allopaths were satisfied with R/S healers (p = 0.0019). Furthermore, 91.1 % TCAM and 73.1 % allopaths (p = 0.000) believe that mental health stigma can be minimized by integrating with spiritual care services. Overall, 87 % of TCAM and 73 % of allopaths agreed to primary criterion variable: 'spiritual healing is beneficial and complementary to psychiatric care.' A quarter of allopaths (24.4 %) and 38 % of TCAM physicians reportedly cross-refer their grieving patients to religious/TCAM healer and psychiatrist/psychologist, respectively; on logistic regression, significant (p < 0.05) predictors were clinical interactions/references to r/s healers. Providing spiritual care within the setup of psychiatric institution will not only complement psychiatric care but also alleviate stigma against mental health services. Implications on developing spiritual care services like clinical chaplaincy are discussed.

Generation of soluble NKG2D ligands: proteolytic cleavage, exosome secretion and functional implications.

The activating natural killer group 2 member D (NKG2D) receptor is expressed on NK cells, cytotoxic T cells and additional T cell subsets. Ligands for human NKG2D comprise two groups of MHC class I-related molecules, the MHC class I chain-related proteins A and B (MICA/B) and 6 UL16-binding proteins (ULBP1-6). While NKG2D ligands are absent from most normal cells, expression is induced upon stress and malignant transformation. In fact, most solid tumours and leukaemia/lymphomas constitutively express at least one NKG2D ligand and thereby are susceptible to NKG2D-dependent immunosurveillance. However, soluble NKG2D ligands are released from tumour cells and can down-modulate NKG2D activation as a means of tumour immune escape. In some tumour entities, levels of soluble NKG2D ligands in the serum correlate with tumour progression. NKG2D ligands can be proteolytically shed from the cell surface or liberated from the membrane by phospholipase C in the case of glycosylphosphatidylinositol (GPI)-anchored molecules. Moreover, NKG2D ligands can be secreted in exosomal microvesicles together with other tumour-derived molecules. Depending on the specific tumour/immune cell setting, these various forms of soluble and/or exosome-bound NKG2D ligands can exert multiple effects on NKG2D/NKG2D ligand interactions. In this review, we focus on the role of various proteases in the shedding of human NKG2D ligands from tumour cells and discuss the not completely unanimous reported functional implications of soluble and exosome-secreted NKG2D ligands for immunosurveillance.

Exploring knowledge and healthseeking behaviour related to sexually transmitted infections among the tribal population of Madhya Pradesh, central India.

This community-based cross-sectional study was carried out in the tribal population of randomly selected villages of Jabalpur district, Madhya Pradesh, central India. A total of 200 married men and women aged 15­49 years were interviewed to explore their knowledge, experience and health-seeking behaviour related to sexually transmitted infections (STIs). Though 91% of respondents were aware of STIs, the sexual route was mentioned by only 19%as the route of transmission. Around 18% reported a need for social isolation from persons with STIs. Though 88% of the respondents felt modern medicine was the best remedy for STIs, only a few of them used medical treatment while suffering from an STI. Twenty-seven per cent of respondents resorted to traditional healers, and 30% utilized home remedies for STI treatment. The study highlights a need for generating STI awareness amongst the tribal population of the region through a needs-based behaviour change communication (BCC)strategy.

ETC Model: How One Small Dialysis Organization Is Navigating Uncharted Policy Waters.

The ETC model proposes to increase access to home dialysis and transplant for patients with ESRD. Implementation of this model is happening while many dialysis organizations are still suffering the far-reaching effects of the coronavirus disease 2019 (COVID-19) pandemic. In addition, the model has the potential to negatively affect small and independent dialysis organizations disproportionately. It incentivizes home dialysis over transplant and promotes development of new home dialysis programs, rewards achievement over improvement, and places an excessive burden on small and independent dialysis organizations. Advantages of the program include the focus on self-care as an acceptable alternative to home dialysis for some patients and the potential for some organizations to make improvements in care with increased reimbursements. The authors hope that the Centers for Medicare and Medicaid Services will address many of these concerns in updated rulemaking and guidance.

TB free India: Reaching the unreached tribal population under National Tuberculosis Elimination Programme.

India is the highest TB burden country in the world. The burden however is not uniform in different strata including tribal population - one of the key affected populations in the country. As the evidences from tribal population are hardly available, most of the policies and strategies implemented under National Tuberculosis Elimination Programme (NTEP) are usually based on the evidences from general populations. NTEP is continuously taking steps to strengthen TB services in tribal areas. The Social Action Plan including Tribal Action Plan is in place and the appropriate strategies are incorporated in the National Strategic Plan (NSP) to ensure universal access to quality TB services to vulnerable population groups. However, its implementation becomes challenging especially in tribal areas as different tribal groups have their own unique ways of dealing with health issues. These issues are therefore required to be addressed holistically involving all the stakeholders. In view of this a symposium was jointly organized by the Central TB Division (CTD), Govt. of India and ICMR - National Institute of Research in Tribal Health (NIRTH), Jabalpur on 17th and 18th December, 2019 at ICMR - NIRTH, Jabalpur. It provided an excellent platform for all the stakeholders from different parts of the country to share their experiences in tuberculosis particularly among marginalized populations. The recommendations emerged out of this interactive symposium highlight the sincere effort of NTEP to tackle TB situation in tribal population and show the way forward towards India's TB elimination goal by 2025 especially in hard to reach tribal areas.

Anatomical and fMRI-network comparison of multiple DLPFC targeting strategies for repetitive transcranial magnetic stimulation treatment of depression.

BACKGROUND: The efficacy of repetitive transcranial magnetic stimulation (rTMS) for depression may vary depending on the subregion stimulated within the dorsolateral prefrontal cortex (DLPFC). Clinical TMS typically uses scalp-based landmarks for DLPFC targeting, rather than individualized MRI guidance. OBJECTIVE: In rTMS patients, determine the brain systems targeted by multiple DLPFC stimulation rules by computing several surrogate measures: underlying brain targets labeled with connectivity-based atlases, subgenual cingulate anticorrelation strength, and functionally connected networks. METHODS: Forty-nine patients in a randomized controlled trial of rTMS therapy for treatment resistant major depression underwent structural and functional MRI. DLPFC rules were applied virtually using MR-image guidance. Underlying cortical regions were labeled, and connectivity with the subgenual cingulate and whole-brain computed. RESULTS: Scalp-targeting rules applied post hoc to these MRIs that adjusted for head size, including Beam F3, were comparably precise, successful in directly targeting classical DLPFC and frontal networks, and anticorrelated with the subgenual cingulate. In contrast, all rules involving fixed distances introduced variability in regions and networks targeted. The 5 cm rule targeted a transitional DLPFC region with a different connectivity profile from the adjusted rules. Seed-based connectivity analyses identified multiple regions, such as posterior cingulate and inferior parietal lobe, that warrant further study in order to understand their potential contribution to clinical response. CONCLUSION: EEG-based rules consistently targeted DLPFC brain regions with resting-state fMRI features known to be associated with depression response. These results provide a bridge from lab to clinic by enabling clinicians to relate scalp-targeting rules to functionally connected brain systems.

Drug-induced bullous pemphigoid: cases triggered by intravenous iodine and etanercept.

Bullous pemphigoid (BP) is one of the most common acquired immunobullous diseases. Rarely, the development of BP is attributed to drug exposure. We present two cases of BP, one triggered by intravenous iodine, and one associated with etanercept treatment in a patient with psoriasis; the first time, to our knowledge, that either of these associations has been reported. The recognition of occasional cases of drug-induced BP such as ours, with timely cessation of the offending agent, may produce rapid clinical improvement with decreased exposure to potent immunosuppressive therapy.
