Factors associated with treatment adherence among pulmonary tuberculosis patients in New Delhi.

BACKGROUND: TB is treated with a six-month course of four antimicrobial drugs, and nearly all cases of TB can be cured if the medications are given and taken correctly. Due to its prolong treatment plans, there can be reasons associated with non-adherence to treatment by TB patients. Hence, the present study aimed to explore the factors associated with medication adherence among TB patients. METHOD: A cross-sectional descriptive survey was conducted among adult pulmonary tuberculosis patients enrolled under RNTCP (now NTEP) in New Delhi among 27 functional RNTCP districts. Around 200 TB patients who are enrolled in the Nikshay App and are also on treatment were considered. A structured questionnaire was prepared for the interview guide. Analysis was done using bivariate analysis, chi-square tests, and Fisher's exact tests. RESULTS: Among the total participants, 173 (86.5%) were adherent and the remaining 27 (13.5%) participants were non-adherent. The majority of the participants (91%) said they were able to follow the routine to the DOTS center, and 9% said they find it difficult to report to the DOTS center as per their schedule. Only 12.35% of non-adherent participants were seen among those who get regular reminders from their families to take medicines, as compared to 18.42% among those who did not get regular reminders from their families. More than one-fourth of the participants (25.9%) who report not getting necessary motivation from healthcare providers were non-adherent. Motivation by healthcare workers to follow drug schedules was found statistically significant to treatment compliance with a P-value of 0.0422. CONCLUSION: TB is a curable disease; this belief has turned out to be a motivational factor for patients suffering from this disease. Studies have shown that faith in the efficacy of treatment helps adherence to TB treatment while other studies describe how patient adherence was adversely affected by the belief that TB is incurable or the treatment is inefficient or that alternative treatment such as traditional medicine is better.

Copper nanoparticles loaded gelatin/ polyvinyl alcohol/ guar gum-based 3D printable multimaterial hydrogel for tissue engineering applications.

Hydrogels are becoming increasingly significant in tissue engineering because of their numerous benefits, including biocompatibility, biodegradability, and their ability to provide a supportive structure for cell proliferation. This study presents the synthesis and characterization of a new multimaterial hydrogel with 3D-printing capabilities composed of copper nanoparticle-reinforced gelatin, polyvinyl alcohol (PVA), and guar gum-based biomaterials intended for tissue engineering applications. Combining CuNPs aims to enhance the hydrogel's antibacterial properties, mechanical strength, and bioactivity, which are essential for successful tissue regeneration. Hydrogels are chemically cross-linked with glyoxal and analyzed through different assessments to examine the compressive behavior, surface morphology, sorbing capacity, biocompatibility, thermal stability, and degradation properties. The results demonstrated that including CuNPs significantly improved the hydrogel's compressive modulus (4.18 MPa) for the hydrogel with the CuNPs and provided better antibacterial activity against common pathogens with controlled degradation. All the hydrogels exhibited a lower coefficient of friction, which was below 0.1. In vitro cell culture studies using chondrocytes indicated that the CuNPs-loaded hydrogel supported cell proliferation and growth of chondrogenic genes such as collagen type II (COL2) and aggrecan (ACAN). The biocompatibility and enhanced mechanical properties of the multimaterial hydrogel make it a promising candidate for developing customized, patient-specific tissue engineering scaffolds.

Feasibility and efficacy of virtual reality rehabilitation compared with conventional physiotherapy for upper extremity impairment due to ischaemic stroke: protocol for a randomised controlled trial.

INTRODUCTION: Approximately half of all stroke survivors have persistent upper extremity functional impairment, leading to reduced self-care, independence and quality of life. High-intensity, task-oriented virtual reality rehabilitation improves motor recovery. However, its clinical efficacy over standard rehabilitation remains uncertain. This study aims to evaluate the feasibility and efficacy of a virtual reality-based comprehensive rehabilitation gaming system (VR-cRGS) in stroke survivors with upper extremity impairment and to characterise the structural and functional plasticity of the affected regions in the brain due to the proposed rehabilitation. METHODS AND ANALYSIS: This study is a multicentric, open-label, randomised controlled trial with an intention-to-treat analysis. A total of 162 patients will be enrolled in two academic institutes in India that specialise in stroke care. Patients with a first-ever ischaemic stroke (18-70 years and 1-6 months of stroke onset) with upper extremity impairment with 1 and 1+ grades of spasticity as per the modified Ashworth Scale and 3, 4 or 5 stages on Brunnstrom recovery staging will be enrolled. They will be randomised (1:1) into two treatment groups to receive 12 weeks of training either on VR-cRGS or on conventional physiotherapy. The primary feasibility outcome is compliance with the treatment. The primary efficacy outcome is the functional recovery of the upper extremity assessed by the Fugl-Meyer Assessment-Upper Extremity and Wolf Motor Function Test. The secondary outcomes are the Barthel Index and the 36-item Short-Form Health Survey. Multimodal brain imaging will be done in all enrolled patients at baseline and post-treatment to evaluate the structural and functional connectivity changes. The outcome measures will be analysed using paired t-tests or non-parametric tests. ETHICS AND DISSEMINATION: The study has been approved by the Institutional Ethics Review Board of the Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, Kerala, India (SCT/IEC/1415/AUGUST-2019) and the National Institute of Mental Health and Neurosciences, Bengaluru, Karnataka, India (NIMHANS/IEC (BS and NS DIV.)/32nd Meeting/21). All participants will sign an informed consent form prior to participation. The study results will be disseminated through scholarly publication. TRIAL REGISTRATION NUMBER: CTRI/2021/11/038339.

Voices of care: unveiling patient journeys in primary care for hypertension and diabetes management in Kerala, India.

Background: Diabetes and hypertension are leading public health problems, particularly affecting low- and middle-income countries, with considerable variations in the care continuum between different age, socio-economic, and rural and urban groups. In this qualitative study, examining the factors affecting access to healthcare in Kerala, we aim to explore the healthcare-seeking pathways of people living with diabetes and hypertension. Methods: We conducted 20 semi-structured interviews and one focus group discussion (FGD) on a purposive sample of people living with diabetes and hypertension. Participants were recruited at four primary care facilities in Malappuram district of Kerala. Interviews were transcribed and analyzed deductively and inductively using thematic analysis underpinned by Levesque et al.'s framework. Results: The patient journey in managing diabetes and hypertension is complex, involving multiple entry and exit points within the healthcare system. Patients did not perceive Primary Health Centres (PHCs) as their initial points of access to healthcare, despite recognizing their value for specific services. Numerous social, cultural, economic, and health system determinants underpinned access to healthcare. These included limited patient knowledge of their condition, self-medication practices, lack of trust/support, high out-of-pocket expenditure, unavailability of medicines, physical distance to health facilities, and attitude of healthcare providers. Conclusion: The study underscores the need to improve access to timely diagnosis, treatment, and ongoing care for diabetes and hypertension at the lower level of the healthcare system. Currently, primary healthcare services do not align with the "felt needs" of the community. Practical recommendations to address the social, cultural, economic, and health system determinants include enabling and empowering people with diabetes and hypertension and their families to engage in self-management, improving existing health information systems, ensuring the availability of diagnostics and first-line drug therapy for diabetes and hypertension, and encouraging the use of single-pill combination (SPC) medications to reduce pill burden. Ensuring equitable access to drugs may improve hypertension and diabetes control in most disadvantaged groups. Furthermore, a more comprehensive approach to healthcare policy that recognizes the interconnectedness of non-communicable diseases (NCDs) and their social determinants is essential.

Primary Angiitis of the CNS: Differences in the Profile Between Subtypes and Outcomes From an Indian Cohort.

BACKGROUND AND OBJECTIVES: Primary angiitis of the CNS (PACNS) is a rare disease that has significant morbidity and mortality. Subtypes of PACNS can have different presentations that could be missed with certain diagnostic modalities, further increasing diagnostic complexity. We sought to distinguish the subtypes of PACNS and describe their outcomes in an Indian cohort. METHODS: Adult patients in this retrospective single-center cohort study were reviewed from the PACNS database between 2000 and 2019. Diagnosis was made as per Calabrese and Malleck criteria. Small and medium vessel vasculitis was defined, and their clinical and radiologic profile, treatment, and outcomes were compared. Functional outcomes were noted at 6-month, 1-year, and at last follow-up, while relapses were noted at last follow-up. A poor outcome was defined as modified Rankin Scale >2. RESULTS: Seventy-two patients fulfilled the inclusion criteria of whom 50 (69.4%) were male. The small vessel vasculitis subtype had a younger age at onset (30.5 vs 40.5 years, p = 0.014), presented less often as a stroke (22% vs 62%, p = 0.001), and had greater delay in diagnosis and treatment initiation (median of 620 days vs 118 days, p = 0.001) compared with medium vessel vasculitis subtype. Although no difference was noted at 6 months, the small vessel vasculitis group had poor outcomes at 1-year and last follow-up (57% vs 20%, p = 0.011 and 72% vs 34%, p = 0.005, respectively) and had more relapses at last follow-up (89% vs 30%, p < 0.001) when compared with the medium vessel vasculitis group. On analyzing the entire cohort, 50 of 72 (69%) and 37 of 53 (69.8%) patients had a good outcome at 6 months and 1 year, respectively. Relapse was noted in 35 of 72 (49%) at final follow-up. The choice of the treatment regimen did not predict outcomes or relapses. DISCUSSION: The small vessel vasculitis subtype of PACNS is a distinct entity that has diagnostic and treatment delays with poor long-term outcomes and more relapses. Recognizing the different subtypes of PACNS may help to expedite diagnosis and plan treatment.

Real-Life Disability-Adjusted Life Years (DALY) Capture the Disability of Epilepsy Better from an Individual's Perspective.

Background and Objective: For 1.3 billion population in India, there are only scarce reports on disability of epilepsy using disability-adjusted life year (DALY) as a measure. Our objective was to estimate DALY using real-life data over a period of time for a cohort of people with epilepsy (PWE) admitted to an Epilepsy Monitoring Unit (EMU) of a tertiary care epilepsy center. Materials and Methods: : We ascertained survival status as on December 31, 2016 of all eligible admissions to the EMU between 01/01/2005 and 12/31/2015. We examined the medical records of randomly selected 200 of the 1970 survivors and all the expired PWE (n = 40) for clinical characteristics. The cumulative real-life DALY (cr-DALY) for individual was calculated as the sum of the years lost to disability (YLD) and the years of life lost (YLL). Annual population-based DALY (p-DALY) was estimated from the cr-DALY, total patient-years of follow-up, and regional population prevalence. Results: The cr-DALY per PWE was 17.63 (generalized seizures only). The cr-DALY increased by 23.7% when all seizure types were considered (23.12). PWE with epilepsy onset <10 years of age, focal epilepsy (particularly, extratemporal lobe epilepsy), and premature death had significantly higher cr-DALY. Those who underwent surgery for epilepsy or achieved remission had significantly lower cr-DALY. The computed p-DALY was 583/1,00,000 population (generalized epilepsy contributed 165/1,00,000 population; focal epilepsy contributed 418/1,00,000 population). Conclusion: Our study had identified, for the first time, several determinants that reduced DALY significantly. Real-life DALY, rather than prevalence-based DALY, captures the cumulative disability of affected individuals. Epilepsy leads to loss of 23 years of disability-adjusted life span for the affected person. This can be extrapolated to substantial economic benefits.

Building risk mitigation strategies for circularity adoption in Indian textile supply chains.

Textile industries are among the most polluting and demand urgent management measures to mitigate their negative environmental impact. Thus, it is imperative to incorporate the textile industry into the circular economy and to foster sustainable practices. This study aims to establish a comprehensive, compliant decision framework to analyse risk mitigation strategies for circular supply chain (CSC) adoption in India's textile industries. The Situations Actors Processes and Learnings Actions Performances (SAP-LAP) technique analyses the problem. However, interpreting the interacting associations between the SAP-LAP model-based variables is somewhat lacking in this procedure, which might skew the decision-making process. As a result, in this study, the SAP-LAP method is accompanied by a novel ranking technique, namely, the Interpretive Ranking Process (IRP), which reduces decision-making issues in the SAP-LAP method and aids in evaluating the model by determining the ranks of variables; furthermore, the study also offers causal relationships among the various risks and risk factors and various identified risk-mitigation actions by constructing Bayesian Networks (BN) based on conditional probabilities. The study's originality represents the findings using an instinctive and interpretative choice approach to address significant concerns in risk perception and mitigation techniques for CSC adoption in the Indian textile industries. The suggested SAP-LAP and the IRP-based model would assist firms in addressing risk mitigation techniques for CSC adoption concerns by providing a hierarchy of the various risks and mitigation strategies to cope with. The simultaneously proposed BN model will help visualise the conditional dependency of risks and factors with proposed mitigating actions.

Ayurvedic Treatment in the Rehabilitation of Ischemic Stroke Patients in India: A Randomized Controlled Trial Study Protocol.

In patients with ischemic stroke, motor and sensory impairments are common and are associated with functional disability. Conventional physiotherapy (CP) is the primary modality of rehabilitation for post-stroke sensorimotor dysfunction. Ayurveda is a commonly practiced alternative system of medicine that offers unique rehabilitative measures for post-stroke recovery. We hypothesize that Ayurvedic rehabilitative treatment (ART) is superior to similar duration CP in improving the sensorimotor recovery of patients with ischemic stroke at 90 days after enrollment. AyuRvedic TrEatment in the Rehabilitation of Ischemic STrOke Patients in India: A Randomized controllEd trial (RESTORE) is an investigator-initiated, multicenter, prospective, randomized, controlled, parallel-arm, blinded outcome assessment trial being conducted under the Indian Stroke Clinical Trial (INSTRuCT) Network across the four comprehensive stroke centers in India. Consecutive hemodynamically stable adult patients with their first acute ischemic stroke between 1 and 3 months from stroke onset are being randomized (1:1) into two treatment groups to receive either 1 month of ART or 1 month of CP. The primary outcome measure is the Fugl Meyer Assessment-upper extremity for physical performance at 90 days. The secondary outcomes are the modified Rankin Scale, Barthel Index, Berg Balance, and SF-36 at 90 days. The safety outcomes include a composite of irreversible morbidity and mortality. A sample size of 140 (70 in each group) patients with ischemic stroke will allow us to detect a minimal clinical important difference of 9.4 (standard deviation) with superiority margin of 5, an attrition rate of 10%, alpha of 5%, and power of 80%. This randomized trial will systematically assess the efficacy and safety of traditional ART compared to CP. The trial has been registered in the Clinical Trial Registry India (CTRI/2018/04/013379).

Effectiveness of an oral health education intervention among 6-12-year-old children: A cluster randomized controlled trial.

OBJECTIVES: Literature on the effectiveness of theory-based oral health education on the oral hygiene of children is limited. We aimed to determine the effectiveness of an health behaviour theory-based school oral health education intervention on 1) oral hygiene and 2) oral health-related knowledge, attitude and practices among 6-12-year-old children in Kerala, India. METHODS: Cluster randomized controlled trial. Sixteen class divisions (clusters) were randomized into intervention and control groups of 225 and 228 children respectively. Primary and secondary outcomes were plaque score as measured using the simplified oral hygiene index (OHI-S) and oral health-related knowledge, attitude and practices respectively. The intervention group received structured oral health education classes for three months and materials including pamphlets. Children in the control group were not given the classes or materials. RESULTS: Post-intervention OHI-S scores in the intervention group and control groups were 1.65 and 2.17 respectively (difference = -0.52, 95%CI -0.86, -0.18). All the secondary outcomes improved in the intervention group compared to the control group. CONCLUSIONS: The intervention improved the oral hygiene status, oral health-related knowledge, attitude and practices of the children. Longer term follow-up and economic appraisal are needed to help policymakers plan and develop OHEI based on health behaviour theories.

First report of Athelia rolfsii (=Sclerotium rolfsii) associated with foot rot disease of Chrysanthemum morifolium in India.

Chrysanthemum morifolium L. is an important flower crop grown in different parts of Karnataka for its striking cut flowers and international market value. During a field survey (Mysore district, Karnataka, February, 2022), chrysanthemum fields were found infected with foot rot disease. The presence of white mycelial structures with sclerotia were recorded near the stem-soil interface. The disease incidence ranged 10-12% measured in an area of approximately 10 hectares. The infected plants showed quick wilt, yellowing and toppling of the entire plant. Infected plants from Doddamaragowdanahally and Rayanahally (n=15) were collected and associated fungal pathogen isolated after surface sterilization with NaOCl (1%) on potato dextrose agar (PDA) amended with chloramphenicol (50 mg/L). Fungal mycelia developed from the infected tissues were inoculated on to fresh PDA plates to obtained pure cultures for further identification. Fungal colonies with dense, aerial whitish-cottony mycelia with uniformly globoid sclerotia (0.284.2 mm) were observed after 15 days of incubation (28 ± 2°C). Sclerotia were white in the beginning and turned brown at maturity. The average number of sclerotia produced per plate ranged from 240 to >480 (n = 10). To further to confirm the identity of the isolates, two representative isolates (CmSr1 and CmSr2) was subjected to molecular identification based on ITS-rDNA sequences. Briefly, genomic DNA was isolated from 12 day old cultures using the CTAB method and ITS-rDNA was amplified using ITS1-ITS4 primers (White et al., 1990). An expected amplicon of >650 bp (ITS) was obtained and later sequenced from both the directions. The consensus sequences were analysed through nBLAST search which revealed that 100% sequence similarity with reference sequences of Athelia rolfsii (S. rolfsii) from GenBank database (MT127465, MN974137, KC292637; identity 656/656; 0 gaps). A phylogenetic tree obtained by the neighbor-joining method using MEGAX shared a common clade with the reference sequences retrieved and computed, thus confirming the identification based on sequence analysis and molecular phylogeny. The representative sequence of A. rolfsii isolates CmSr1 and CmSr2 isolates deposited in GenBank with Accession nos. ON456153 and ON456154, respectively. Based on etiology, morphological, cultural and molecular data the pathogen was identified as Athelia rolfsii (Curzi) Tu & Kimbrough (Syn: Sclerotium rolfsii Sacc.) (Mordue, 1974; Mahadevakumar et al., 2016, 2018). Plants (n=60) were inoculated with sclerotial bodies (2 sclerotia/plant) near stem soil interface under green house and covered with polythene bags (at 27 ± 2°C and 80% RH). Non-inoculated plants (n=20) served as controls. The development of foot rot disease was observed eight days after inoculation. A total of 48 plants showed the foot rot symptoms and 12 inoculated plants and control plants remained healthy. The identity of the fungus was confirmed by morphological and cultural characters after re-isolation. C. morifolium is an important flower crop in Karnataka. S. rolfsii is known to be associated with blight and collar rot of Chrysanthemum spp. from Kerala (Beena et al., 2002) but no species (host) identity provided. Therefore, to the best of our knowledge, this is the first report of foot rot disease caused by Athelia rolfsii on C. morifolium in India. Early diagnosis of this disease will help the farmers to adopt suitable management practices to avoid loss.

END TB initiative - involving youth - challenges and solutions.

WHO has given a special call to involve youth in END TB initiative. Involvement of youth, especially in the medical fraternity, in the TB control activities can ensure we reach our goal of ending TB in India by 2025. This study was planned to recruit and monitor young volunteers from medical colleges of Andhra Pradesh. 183 volunteers were recruited from 15 medical colleges and were tasked to spread awareness among general public. Work of these volunteers was monitored via Whatsapp group chats and videoconferencing. 4 follow-up meetings were held via videoconferencing and various hurdles and challenges were discussed. Major challenges faced included lack of physical meetings due to COVID-19 pandemic, which adversely affected their motivation and monitoring activities. Increased involvement from medical colleges, regular telecommunication and meetings can improve the work and motivation of these volunteers.

Dibenzyl (benzo [d] thiazol-2-yl (hydroxy) methyl) phosphonate (DBTMP) showing anti-S. aureus and anti-biofilm properties by elevating activities of serine protease (SspA) and cysteine protease staphopain B (SspB).

Staphylococcus aureus biofilms are the pathogenic factor in the spread of infection and are more pronounced in multidrug-resistant strains of S. aureus, where high expression of proteases is observed. Among various proteases, Serine protease (SspA) and cysteine protease Staphopain B (SspB) are known to play a key role in the biofilm formation and removal of biofilms. In earlier studies, we have reported Dibenzyl (benzo [d] thiazol-2-yl (hydroxy) methyl) phosphonate (DBTMP) exhibits anti-S. aureus and anti-biofilm properties by elevating the expression of the protease. In this study, the effect of DBTMP on the activities of SspA, and SspB of S. aureus was evaluated. The SspA and SspB genes of S. aureus ATCC12600 were sequenced (Genbank accession numbers: MZ456982 and MW574006). In S. aureus active SspA is formed by proteolytic cleavage of immature SspA, to get this mature SspA (mSspA), we have PCR amplified the mSspA sequence from the SspA gene. The mSspA and SspB genes were cloned, expressed, and characterized. The pure recombinant proteins rSspB and rmSspA exhibited a single band in SDS-PAGE with a molecular weight of 40 and 30 KD, respectively. The activities of rmSspA and rSspB are 32.33 and 35.45 Units/mL correspondingly. DBTMP elevated the activities of rmSspA and rSspB by docking with respective enzymes. This compound disrupted the biofilms formed by the multidrug-resistant strains of S. aureus and further prevented biofilm formation. These findings explain that DBTMP possesses anti-S. aureus and anti-biofilm features.

Resilience and complexity measurement for energy efficient global supply chains in disruptive events.

The whole world is faced with the COVID-19 epidemic that causes major disruptions in global supply chains. The aim of study is to evaluate the effects of COVID-19 on energy efficient global supply chains (SCs) and to model the global supply chain resilience and energy management affected during the COVID-19 considering trade between Turkey and China, and Turkey and the EU. In this study, firstly using System Dynamics (SD) model, the behavior of countries against COVID-19 for a certain period of time is observed, subsequently the increase in complexity is analyzed with entropy measurement to determine whether the systems are resilient or not and to mark the differences arising from reporting in the first and second wave of the pandemic in the developed model. It is determined that the second wave reporting differences is less than first wave reporting differences except Turkey. From the learning effect perspective, it has been seen that the effect on the economy and foreign trade are less than first wave of pandemic even though the number of patients originating in the second wave are higher. It means that countries responded to the second wave of COVID-19 in a more resilient way. It is found that as a major finding of this study, perceived complexity of the system decreases in the second wave because of the resilience of supply chain considering learning effect and centralized decision making ensure increasing resilience and resilience measure in global supply chains. The study is highly helpful for governments, decision makers and managers to understand and manage the impacts of COVID-19 on global supply chains being resilient and energy efficient.

A systematic review on SARS-CoV-2 remission: an emerging challenge for its management, treatment, immunization strategies, and post-treatment guidelines.

The COVID-19 disease caused by severe acute respiratory syndrome coronavirus -2 (SARS-CoV-2) has posed as a major health concern for people all across the globe. Along with the increasing confirmed patients being readmitted with complaints for fever, cough, cold, the effective monitoring of 'relapse' of the SARS-CoV-2 virus in the previously discharged patients have become the next area of focus. However, availability of limited data on reactivation of SARS-CoV-2 makes the disease prognosis as well as the effective control of re-infection an immense challenge. Prompted by these challenges, we assessed the possibility of re-infection in discharged patients and the risk of the transmission, proficiency of RT-PCR results and approximate period required for the quarantine, and the real challenges for the development of vaccine. In the present review, the published literature on all the possible cases of re-infection from February to July were reported, thereby selected 142 studies from a hub of overall 669 studies after full text screening. The incomplete virus clearance, poor sensitivity of the present diagnostic testing, emergence of mutant strains, insufficient mucus collection from the throat swab etc., are some of the possible causes of re-infection. The new protocols for management of COVID-19 discharged patients should be revised in the guidelines.

Health Problems and Healthcare-Seeking Practices of Workers Processing E-Waste in the Unorganized Sector in the Slums of a South Indian City: An Exploratory Study.

Context: The precarious nature of the work in the unorganized e-waste processing sector poses a threat to workers' health by making them vulnerable to occupational injuries as well as other work-related diseases in addition to job insecurity and related issues. Aims: To systematically explore and quantify employment and working conditions along with the occupational health problems and healthcare-seeking practices of workers processing e-waste in the slums of a south Indian city. Settings and Design: Cross-sectional study conducted in the slums of a south Indian city. Methods and Material: We used a structured interview schedule among 248 randomly selected workers. Statistical Analysis Used: Descriptive statistics were utilized to summarize the results. 95% CI was calculated for select proportions. Chi-square tests were used to determine statistical significance. Results: We found a predominance of self-employment; unclear employment relationship; no paid holidays; long working hours; unequal wages; absence of work-related social security; absent workers' organization; rented units; minimal/no use of safety equipment, no concept of good ergonomic practices. The commonest occupational health concerns were injuries (17% & 41% respectively) and musculoskeletal problems (43.5%). Private/charitable clinics were the commonest source of seeking healthcare which contributed to 'irrational' practices in the form of repeated TT injections. Conclusions: Findings suggest that the precarious work in the unorganized e-waste processing sector could not only give rise to health problems but also make workers undermine the severity of their health problems. The non-responsiveness of the local public healthcare system compels them to rely on private and charitable clinics and pay for services that are otherwise freely available in UPHCs.

Elicitation of defense response by transglycosylated chitooligosaccharides in rice seedlings.

Long-chain chitooligosaccharides (COS) with degree of polymerization (DP) more than 4 are known to have potential biological activities. A hyper-transglycosylating mutant of an endo-chitinase from Serratia proteamaculans (SpChiD-Y28A) was used to synthesize COS with DP6 and DP7 using COS DP5 as substrate. Purified COS with DP5-7 were tested to elicit the defense response in rice seedlings. Among the COS used, DP7 strongly induced oxidative burst response as well as peroxidase, and phenylalanine ammonia lyase activites. A few selected marker genes in salicylic acid (SA)- and jasmonic acid-dependent pathways were evaluated by real-time PCR. The expression levels of pathogenesis-related (PR) genes PR1a and PR10 and defense response genes (chitinase1, peroxidase and ß -1,3-glucanase) were up regulated upon COS treatment in rice seedlings. The DP7 induced Phenylalanine ammonia lyase and Isochorismate synthase 1 genes, with concomitant increase of Mitogen-activated protein kinase 6 and WRKY45 transcription factor genes indicated the possible role of phosphorylation in the transmission of a signal to induce SA-mediated defense response in rice.

Consumption of fruits, vegetables and salt in the context of control of type 2 diabetes and hypertension in Kerala, India.

BACKGROUND: Proper diet is necessary to control hypertension and diabetes. This paper describes the combined fruit and vegetable, and salt intake of adults (>=18 years) who were detected to have hypertension or diabetes. METHODS: We analysed the data from a state-wide survey of 12012 adults using the World Health Organization STEPs for NCD risk factor surveillance. We evaluated the recommended intake of fruit and vegetable (>=5 servings/day) and salt (<5 gm/day) across participants divided into four strata, and the probabilities were also estimated using the fitted multiple binary logistic regression models. RESULTS: Overall, 13.9% (95%CI: 12.2%-15.9%) and 29.4% (95%CI: 28%-30.8%) of participants consumed the recommended level of fruit and vegetable, and salt, respectively. Adjusted odds ratios were not significantly different across the four strata based on the status of treatment and control of diabetes or hypertension. The likelihood of following the recommended fruit and vegetable intake was highest for 50-69-year-old females with above high school education, obese, under treatment for diabetes or hypertension, and had normal values of FBS and BP (0.28). The likelihood for recommended salt intake was highest for 50-69-year-old males with above high school education and had normal BMI, under treatment for diabetes or hypertension, and had normal values of FBS and BP (0.69). CONCLUSION: The status of diabetes or hypertension did not show considerable influence in the fruit, vegetable, and salt intake of adults in general. A detailed exploration of the accessibility and acceptability of such recommended intakes in the Kerala context is warranted.

Preparedness of primary and secondary health facilities in India to address major noncommunicable diseases: results of a National Noncommunicable Disease Monitoring Survey (NNMS).

BACKGROUND: The monitoring framework for evaluating health system response to noncommunicable diseases (NCDs) include indicators to assess availability of affordable basic technologies and essential medicines to treat them in both public and private primary care facilities. The Government of India launched the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular diseases and Stroke (NPCDCS) in 2010 to strengthen health systems. We assessed availability of trained human resources, essential medicines and technologies for diabetes, cardiovascular and chronic respiratory diseases as one of the components of the National Noncommunicable Disease Monitoring Survey (NNMS - 2017-18). METHODS: NNMS was a cross-sectional survey. Health facility survey component covered three public [Primary health centre (PHC), Community health centre (CHC) and District hospital (DH)] and one private primary in each of the 600 primary sampling units (PSUs) selected by stratified multistage random sampling to be nationally representative. Survey teams interviewed medical officers, laboratory technicians, and pharmacists using an adapted World Health Organization (WHO) - Service Availability and Readiness Assessment (SARA) tool on handhelds with Open Data Kit (ODK) technology. List of essential medicines and technology was according to WHO - Package of Essential Medicines and Technologies for NCDs (PEN) and NPCDCS guidelines for primary and secondary facilities, respectively. Availability was defined as reported to be generally available within facility premises. RESULTS: Total of 537 public and 512 private primary facilities, 386 CHCs and 334 DHs across India were covered. NPCDCS was being implemented in 72.8% of CHCs and 86.8% of DHs. All essential technologies and medicines available to manage three NCDs in primary care varied between 1.1% (95% CI; 0.3-3.3) in rural public to 9.0% (95% CI; 6.2-13.0) in urban private facilities. In NPCDCS implementing districts, 0.4% of CHCs and 14.5% of the DHs were fully equipped. DHs were well staffed, CHCs had deficits in physiotherapist and specialist positions, whereas PHCs reported shortage of nurse-midwives and health assistants. Training under NPCDCS was uniformly poor across all facilities. CONCLUSION: Both private and public primary care facilities and public secondary facilities are currently not adequately prepared to comprehensively address the burden of NCDs in India.

Multi-morbidity and blood pressure control: Results of a cross-sectional study among school teachers in Kerala, India.

The patterns of concordant and discordant comorbidities of hypertension and their association with hypertension control were ascertained in this cross-sectional study. A total of 402 adults with hypertension were identified from the baseline survey of a randomized controlled trial for hypertension control among school teachers in Kerala. Chronic conditions were captured and categorized into concordant and discordant comorbidities. Nearly 57% of teachers with hypertension reported multimorbidity. Concordant morbidity was reported by 44% and discordant by 21% of participants. The odds of hypertension control was higher among those who reported at least one discordant morbidity (odds ratio [OR]: 2.76, 95% confidence interval [CI]:1.69-4.49) and those who reported at least one concordant morbidity (OR: 2.08, CI: 1.37-3.16), compared to their counterparts. Hypertension control was higher for those who reported any comorbidity (OR: 2.37, CI: 1.51-3.71) compared to those who did not report any. Well-designed large-scale mixed methods studies are required to thoroughly explore multimorbidity and its relationship with hypertension control in India.
