RESUMO

Let G be a graph on n vertices with vertex set V(G) and let S⊆V(G) with |S|=α. Denote by GS, the graph obtained from G by adding a self-loop at each of the vertices in S. In this note, we first give an upper bound and a lower bound for the energy of GS (E(GS)) in terms of ordinary energy (E(G)), order (n) and number of self-loops (α). Recently, it is proved that for a bipartite graph GS, E(GS)≥E(G). Here we show that this inequality is strict for an unbalanced bipartite graph GS with 0<α

RESUMO

Background: The cost of illness (COI) for common mental disorders (CMDs) that include depression, anxiety, and somatoform disorder is less studied in India. Hence, we studied the COI and disability of CMDs and their relationship in patients with depression, anxiety, and somatoform disorders. Methods: In this cross-sectional study, we recruited 220 patients (110 with depression, 58 with anxiety disorders, and 52 with somatoform disorders) and evaluated disability using the Sheehan Disability Scale (SDS). The schedule for the cost of illness (S-COI) was used for evaluating COI for the last year. Results: The annual COI of CMDs from the patient perspective was ₹21,620 (interquartile range [IQR], ₹47,761; ≈US$290). The median annual direct COI was ₹4,907 (IQR ₹7,502), and indirect COI was ₹12,900 (IQR ₹37744). The direct COI was 18%, whereas the indirect COI was 82%. The direct and indirect COI in the three groups were similar. In all three groups with ongoing treatment, the mean scores indicated a mild level of disability. Total and indirect COI, but not the direct COI, correlated positively with the severity of illness and disability. Conclusion: All the CMDs with ongoing treatment are associated with a mild level of disability and are a significant financial burden, with higher indirect costs.

RESUMO

Sex determination or sex estimation from a single or fragment of bone is always difficult in the absence of other bones from the same individual. The current study was an attempt to estimate the sex of an individual from the posterior ramus of mandible or the mandibular ramus flexure. A retrospective study was conducted using orthopantomographs (OPGs) of 200 males and 200 females between the age group of 20 - 70 years. Each radiographic image was examined for the presence of a flexure or notching on the posterior border of the ramus in relation to occlusal plane as the method followed by Loth & Henneberg 1996.The study resulted in samples that were correctly classified as females 59.5% and males 57.5 %. The overall correct sex estimation was achieved in 58.5% of the cases. The predictive accuracy or assessment was higher for females compared to males. Consequently, the posterior ramus of mandible or mandibular ramus flexure can be considered as supplementary rather than a definitive means of sex determination. Hence, it is preferable to include as many parameters as possible to attain optimal accuracy.

RESUMO

Background: The greatest contributor to the economic impact of common mental disorders (CMDs) is said to be the loss of work productivity. There is a paucity of studies from India that looks at the impact of CMDs on the productivity of work, which costs both patient and society significantly. Aim: To assess and compare work productivity by evaluating both absolute and relative presenteeism and absenteeism, in persons with CMDs. Materials and Methods: This was a cross-sectional observational study on 220 subjects (110, 58, and 52 patients with depressive disorder, anxiety disorders, and somatoform disorders, respectively), recruited through purposive sampling. We evaluated work productivity using the World Health Organization Health and Work Performance Questionnaire. Results: Absolute absenteeism was significantly different before and after treatment for CMDs as a group but not for individual disorders. Relative absenteeism, absolute presenteeism, and relative presenteeism were all significantly different before and after treatment among both CMDs as a group and also among individual disorders. Both presenteeism and absenteeism (absolute as well as relative) did not differ significantly across the diagnostic groups. Work productivity has been linearly associated with illness severity and disability. Conclusion: CMDs are associated with a significant loss of work productivity. Presenteeism is costlier than absenteeism in affecting work productivity. Loss of work productivity appears to be transdiagnostic across all CMDs. Also, the severity of loss of work productivity is associated linearly with the severity of illness and disability.

RESUMO

Background: Hypothyroidism can predispose systolic and diastolic cardiac dysfunction, increased peripheral vascular resistance, endothelial dysfunction, altered coagulopathy, and dyslipidemia resulting in atherosclerosis. Thyroid hormones can influence homocysteine metabolism by regulating the methylenetetrahydrofolate reductase (M THR). So, this study aimed to compare the markers homocysteine, high sensitive C-reactive protein (hs-CRP), and Atherogenic Indices (AI) between newly diagnosed hypothyroid and euthyroid premenopausal women. Methods: 80 Female patients between 20 and 45 years were enrolled in this study and were equally divided into cases and controls group. Laboratory tests included: i) Serum T3, T4, TSH was measured using electrochemiluminescence, ii) lipid profile, homocysteine, and hs-CRP were measured for all the participants. Atherogenic indices: Castelli risk indices I&II, Atherogenic coefficient (AEC), and Atherogenic Index of Plasma (AIP) were calculated using formulas. A comparison between the study groups was made by using the Independent t-test and Mann-Whitney U test. p-value < 0.05 was considered significant. Results: The hypothyroid group had significantly higher levels of homocysteine (p= 0.014), and hs-CRP (hs-CRP> 3.0 mg/L, 70% of participants have intermediate to high risk for a cardiovascular event) and elevated BMI compared to participants in the euthyroid group. Atherogenic indices (p< 0.001) was significantly increased in the hypothyroid participants' group. TC, TG , and LDL were significantly elevated in the hypothyroid group but did not show any association with systolic and diastolic blood pressure. Conclusions: Premenopausal women with hypothyroidism have a greater predisposition for cardiovascular disease compared to euthyroid.

RESUMO

Ranking watersheds according to their susceptibility to soil erosion is crucial in setting priorities for soil and water conservation initiatives. The main intention of this work is to characterize and prioritize 12-sub-watersheds of the Geba River Basin, northern Ethiopia for planned soil and water conservation practices. SRTM-DEM, GIS, and statistical correlation-based weighted sum approach have been utilized for generating morphometric parameters, data processing, and calculating the combined rank of sub-watersheds respectively. Fourteen morphometric parameters that have high nexus with the soil erosion susceptibility were selected and quantified using different standardized mathematical equations. Based on these quantified variables, a compound factor (rank) was calculated for each sub-watershed. Using the combined rank, the sub-watersheds were clustered into five soil erosion susceptibility zones, i.e., very high, high, moderate, low, and very low. Results revealed that sub-watersheds 7, 8, 9, and 12 which collectively cover the majority of the area (36 % of the total area) are possibly fall under the very high soil erosion susceptibility. The high (comprising of sub-watersheds 1, 5, 11), moderate (consisting of sub-watersheds 2, 3), low (consisting of sub-watershed 10), and very low (consisting of sub-watersheds 4, 6) soil erosion susceptibility zones cover 26%, 28%, 4%, and 6% of the total area respectively. The results further reflect that sub-watersheds in the very high soil erosion susceptibility category require immediate action for implementing soil and water conservation measures. This study's findings could serve as a basis for policymakers and planners in the development of erosion control strategies.

RESUMO

Sustainable agriculture demands the balanced use of inorganic, organic, and microbial biofertilizers for enhanced plant productivity and soil fertility. Plant growth-enhancing rhizospheric bacteria can be an excellent biotechnological tool to augment plant productivity in different agricultural setups. We present an overview of microbial mechanisms which directly or indirectly contribute to plant growth, health, and development under highly variable environmental conditions. The rhizosphere microbiomes promote plant growth, suppress pathogens and nematodes, prime plants immunity, and alleviate abiotic stress. The prospective of beneficial rhizobacteria to facilitate plant growth is of primary importance, particularly under abiotic and biotic stresses. Such microbe can promote plant health, tolerate stress, even remediate soil pollutants, and suppress phytopathogens. Providing extra facts and a superior understanding of microbial traits underlying plant growth promotion can stir the development of microbial-based innovative solutions for the betterment of agriculture. Furthermore, the application of novel scientific approaches for facilitating the design of crop-specific microbial biofertilizers is discussed. In this context, we have highlighted the exercise of "multi-omics" methods for assessing the microbiome's impact on plant growth, health, and overall fitness via analyzing biochemical, physiological, and molecular facets. Furthermore, the role of clustered regularly interspaced short palindromic repeats (CRISPR) based genome alteration and nanotechnology for improving the agronomic performance and rhizosphere microbiome is also briefed. In a nutshell, the paper summarizes the recent vital molecular processes that underlie the different beneficial plant-microbe interactions imperative for enhancing plant fitness and resilience under-challenged agriculture.

RESUMO

This study examines the effect of advancing the breeding season on the reproductive performance of dromedary camels under an intensive management system. Using a synchronization protocol, timed natural mating in female camels was carried out either in September (2 months ahead of the natural breeding season, n = 182) or December (peak breeding season, n = 115). The ovarian responses (size of the dominant follicle at the time of mating and ovulation), pregnancy rate, and pregnancy losses were evaluated using ultrasonography. Blood samples were collected after mating to assess progesterone concentrations by RIA. The libido of male camels (n = 13) was evaluated objectively. Results showed that the percentage of female camels with an optimal sized follicle (11-17 mm) for breeding at the time of mating was lower in September compared to December (81.9 vs 91.3%, P = 0.03). The libido of male camels was lower in September than in December (P <0.001). The ovulation rate (86.3 vs 93.9%, P = 0.04), size of the ovulated follicle (12.7 ± 0.1 vs 13.7 ± 0.2 mm, P <0.001), pregnancy rates on Day 14 (47.8 vs 72.2%, P <0.001) and Day 90 (38.5 vs 60.9%, P <0.001) after mating was lower in September compared to December. However, pregnancy loss was not affected between months (15.7 vs 19.5%, P = 0.3). Among pregnant camels, the progesterone concentrations on Days 6, 8, 10, 12 and 14 after mating were lower in September as compared to December (P <0.001). In non-pregnant camels, the progesterone concentrations on Days 6, 8 and 10 after mating were also lower in September as compared to December (P <0.001). In conclusion, advancing the breeding season by two months, significantly affects the reproductive performance of dromedary camels, yet, acceptable pregnancy rates can be achieved.

RESUMO

Trichoderma spp. is one of the most popular genus of fungi commercially available as a plant growth promoting fungus (PGPF) and biological control agent. More than 80 species of Trichoderma are reported in the literature. However T. asperellum, T. harzianum, T. viride, and T. virens are most commonly utilized as biocontrol agents. Studies were initiated to explore the potential of biocontrol agents in order to develop a cost effective and practical management strategy. Analysis of large number of soil samples collected from western parts of the region led to isolation of native biocontrol agents viz., Trichoderma harzianum, Aspergillus versicolor, and Bacillus firmus from different agricultural systems. These biocontrol agents have proved their antagonistic ability in laboratory tests and field trials. In India, two species of Trichoderma i.e., T. viride and T. harzianum are commercially registered for usage against soil borne plant pathogens mostly as a seed treatment or soil application. There are published scientific papers on the efficacy of T. asperellum and T. virens in India for suppressing pathogens but these are not yet registered under Central Insecticide Board and Registration Committee (CIB & RC). This review article focuses on the uses, commercialization and adoption issues of various fungal and bacterial consortium products in sustainable disease management.

RESUMO

We have developed a simple and convenient method for the synthesis of substituted-aryllidine-2,2-dimethyl-7-thioxo/oxo-4H-[1,3]dioxino[4,5-d]pyrimidine derivatives (4a-g) via one-pot Biginelli reaction of Meldrum's acid (1), indole-3-carbaldehyde/thiophene-2-carbaldehyde/2-chloro-quinoline-3-carbaldehyde (2) and amines (3) in aqueous ethanol in the presence of a catalytic amount of CAN. The obtained pyrimidine hybrids were screened for their antimycobacterial activity against Mycobacterium tuberculi H37RV strain. The antimycobacterial results showed that compounds 4a and 4b exhibited excellent activity with MIC value of 1.6 µg/mL, four-fold greater than the standard streptomycin (6.24 µg/mL), while compounds (4c-g) showed lower efficacy. To study the interaction between the synthesized compounds and receptor, the compounds 4a, 4b, 4c, and 4d were studied for molecular docking on the enzyme enoyl-acyl carrier protein reductase (enoyl-ACP reductase) and the compounds 4a and 4b have emerged as active antitubercular agents with least binding energy -9.4 kcal/mol and -9.3 kcal/mol respectively.

RESUMO

BACKGROUND: A "functional treatment gap" exists in primary care of India despite the higher prevalence of psychiatric disorders at primary care. Traditional classroom training for primary care doctors (PCDs) fails to translate into adequate clinical skills to provide basic psychiatric treatment. An innovative telepsychiatric on-consultation training (Tele-OCT) is designed exclusively for practicing PCDs where a telepsychiatrist trains PCDs in live video streaming of their own real-time general consultations of primary health centres. The aim of this study is to establish performance indicators of Tele-OCT for its effective implementation. METHODOLOGY: The data collected using a file review method from a naturalistic design of the implementation of Tele-OCT for 73 PCDs from August-2016 to October-2018 across Mandya district, Karnataka, India. RESULTS: Flexibility in the scheduling of Tele-OCT sessions is key to success. Personal smartphones of PCDs with available videoconference applications are the popular choice. Four consecutive Tele-OCT sessions are planned for each PCD with a gap of 2-4 weeks over two months. The first three sessions are considered the "optimum Tele-OCT training package" for each PCD, followed by the fourth one as a 'Tele-OCT impact evaluation session' in a live, real-time general consultation. Each Tele-OCT is conducted in an average ten general patients in about two hours per session, totalling about 30 patients in 6 hours of Tele-OCT training package per PCD. Patient's profiles especially common mental disorders are reflective of a true picture of Indian primary care. CONCLUSIONS: Performance indicators of Tele-OCT for future implementation are established. Tele-OCT appears to be a path-breaking training model for PCDs to integrate psychiatric care in their general practice.

RESUMO

BACKGROUND & OBJECTIVES: : Telepsychiatric methods can be used for the purpose of providing clinical care comparable to in-person treatment in various settings including rehabilitation. Previous evidence has shown that clinical outcomes for both are comparable. In view of challenges posed in the implementation of traditional psychiatric care in India, telepsychiatry offers an avenue to provide feasible, affordable and clinically useful psychiatric services. This study was conducted to examine the utility, feasibility and clinical effectiveness of providing collaborative telepsychiatric services with a primary care doctor for inpatients in a rehabilitation centre through a telepsychiatrist of estabilished psychiatry department in a tertiary care centre in south India in a collaborative care model with a primary care doctor. METHODS: : Patients at the rehabilitation centre attached to an urban primary healthcare centre received collaborative care using telepsychiatry for a period from January 2013 to December 2016. A retrospective review of their charts was performed and sociodemographic, clinical and treatment details were collected and analyzed. RESULTS: : The sample population (n=132) consisted of 75 per cent males, with a mean age of 43.8 ± 12.1 yr. Each patient received an average of 7.8 ± 4.9 live video-consultations. Initially, an antipsychotic was prescribed for 84.1 per cent (n=111) of patients. Fifty four patients (40.9%) had a partial response and 26 (19.7%) patients showed a good response. INTERPRETATION & CONCLUSIONS: : The study sample represented the population of homeless persons with mental illness who are often brought to the rehabilitation centre. This study results demonstrated the successful implementation of inpatients collaborative telepsychiatry care model for assessment, follow up, investigation and treatment of patients through teleconsultation.

RESUMO

This study was conducted to develop simple superovulation protocols for dromedary camels using eCG. In experiment 1, camels received either 1000, 2000, 3000, 4000, 5000 or 6000 IU eCG. In experiment 2, camels received either 400 mg FSH (Folltropin-V) twice-daily over 5 days or 3000 IU eCG. In experiment 3, camels received 3000 IU eCG either at 2, 3, 4 or 5 days after ovulation induction. Ovarian response and embryo yield were evaluated in all experiments and embryos collected from camels treated with FSH and eCG were transferred to recipients to examine pregnancy rates. The mean number of ovulations (12.6 ± 1.5 and 13.3 ± 1.2 vs 3.4 ± 0.3, 6.2 ± 0.6 and 9.3 ± 1.0, respectively) and transferable embryos (4.6 ± 1.3 and 4.8 ± 1.0 vs 1.6 ± 0.2, 2.2 ± 0.4 and 1.1 ± 0.4, respectively) with 3000 and 4000 IU eCG doses were higher compared to 1000, 2000 and 6000 IU eCG doses (P < 0.05). Doses of 5000 and 6000 IU eCG resulted in a higher number of unovulatory follicles than other doses (P < 0.05). The FSH treatment resulted in higher number of ovulatory follicles (21.8 ± 1.3 vs 14.8 ± 1.7) and ovulations (18.5 ± 1.1 vs 13.9 ± 1.4) compared to eCG (P < 0.05). However, the number of transferable embryos and pregnancy rates were similar in these treatments. The timing of eCG treatment after ovulation induction did not affect the number of ovulatory follicles and transferable embryos but eCG treatment at 5 days after ovulation induction reduced the number of ovulations (P < 0.05). In conclusion, the optimal dose of eCG to induce superovulation is 3000-4000 IU and it produces a comparable embryo yield to FSH, and can be administered at 2-4 days after ovulation induction.

RESUMO

BACKGROUND: Neurology services in rural and semi-urban part of India are very limited, due to poor infrastructure, resources, and manpower. Tele-neurology consultations at a non-urban setup can be considered as an alternative and innovative approach and have been quite successful in developed countries. Therefore, an initiative to bridge this health gap through Tele-Medicine has been taken by the Government of India. AIM: To study the sociodemographic and clinical profiles of patients who have received collaborative Tele-Neurology consultations from the Tele-Medicine Centre, National Institute of Mental Health and Neurosciences, Bengaluru. METHODOLOGY: We reviewed case files of such patients between December 2010 and March 2017. A total 189 collaborative tele-neurology outpatient consultations were provided through the Tele-Medicine Centre, located at a tertiary hospital-based research centre in southern India. RESULTS: The mean age of the patients was 39.6 (±19) years and 65.6% were aged between 19 to 60 years; 50.8% were male. The most common diagnosis was a seizure disorder in 17.5%, followed by cerebrovascular accident/stroke in 14.8%. Interestingly, 87.3% were found to benefit from tele-neurology consultations using interventions such as a change of medications in 30.1%, referral to a specialist for review in 15.8%, and further evaluation of illness and inpatient care for 7.93%. CONCLUSION: This study has demonstrated the successful implementation of outpatient-based collaborative tele neurology consultation in Karnataka.

RESUMO

This study was conducted to assess the effects of commercial extenders and storage temperature on dromedary camel sperm quality during liquid preservation. In Experiment 1, ejaculates (n = five males; replicated seven times) were split and diluted with synthetic (OPTIXcell, EquiPlus, INRA96, Bioxcell or AndroMed; Experiment 1a) or egg-yolk based (Biladyl, Green buffer or Triladyl; Experiment 1b) extenders and stored for 48 h at 4 °C. In Experiment 2, split ejaculates (n = five males; replicated six times) were used to directly compare Green buffer, OPTIXcell and Triladyl extenders over 48 h of storage at 4 °C. Ejaculates collected in Experiment 3 (n = five males; replicated five times) were diluted with Green buffer or Triladyl before chilled storage for 48 h at 4 or 15 °C. Sperm kinematics, viability and acrosome integrity were assessed during liquid storage. In Experiment 1a, there was the greatest total sperm motility (TM) in the OPTIXcell group following 24 and 48 h of storage, while in Experiment 1b, there was the greatest TM after 48 h of storage with Triladyl and Green buffer. In Experiment 2, there were greater TM and viable acrosome intact spermatozoa in the Triladyl and Green buffer than with OPTIXcell group. In Experiment 3, there was a greater TM in the Triladyl than Green buffer group at 24 and 48 h of storage regardless of storage temperature (which had no effect on sperm quality). In conclusion, camel sperm have greater viability when preserved in liquid form for 48 h following dilution with Triladyl and storage at either 4 or 15 °C.

RESUMO

Reproductive seasonality has been reported in numerous species, including male dromedary camels, yet investigations into seasonal changes in camel semen quality have yet to be conducted. The aim of this study was to characterise the seasonal changes in camel semen quantity and quality as well as correlate these changes to testis and accessory sex gland morphology, sexual behaviour, libido and environmental factors such as day length and ambient temperature in Oman. Semen was collected twice a month for a year and testicular and accessory sex organ biometry recorded once a month via ultrasonography (n = 8 bulls). Blood samples were collected monthly to assess testosterone levels. Results indicated that testes and accessory sex glands size increased during October-April, peaking with testosterone concentrations during January (P<0.05). The sexual behaviour and libido of camels was also greater during the months of October-April (P<0.05). Attempts to collect semen were 100% successful during November-February. Semen volume, as well as sperm gross activity, concentration, motility, average path velocity and percentage with intact acrosomes were the greatest during January and decreased from May-September (P<0.05). Changes in values for semen variables, testosterone concentrations and sex organ anatomy were also highly correlated with seasonal changes in day length and ambient temperatures. In conclusion, a clearly defined reproductive season was observed in male camels in Oman ranging from December-March, with peak reproductive function occurring during December-January. To increase the success of breeding programs, matings or semen collections should be timed to occur when reproductive function is maximal.

RESUMO

Genetic and functional diversity of osmotolerant bacterial endophytes colonizing the root, stem, and leaf tissues of pearl millet genotypes differing in their drought susceptibility was assessed. Two genotypes of pearl millet, viz., the drought tolerant genotype TT-1 and the drought susceptible genotype PPMI-69, were used in the present study. Diazotrophs were found to be the predominant colonizers, followed by the Gram positive bacteria in most of the tissues of both the genotypes. Higher proportion of bacterial endophytes obtained from the drought tolerant genotype was found to be osmotolerant. Results of 16S rRNA gene-ARDRA analysis grouped 50 of the highly osmotolerant isolates into 16 clusters, out of which nine clusters had only one isolate each, indicating their uniqueness. One cluster had 21 isolates and remaining clusters were represented by isolates ranging from two to four. The representative isolates from each cluster were identified, and Bacillus was found to be the most prevalent osmotolerant genera with many different species. Other endophytic bacteria belonged to Pseudomonas sp., Stenotrophomonas sp., and Macrococcus caseolyticus. High phylogenetic diversity was observed in the roots of the drought tolerant genotype while different tissues of the drought susceptible genotype showed less diversity. Isolates of Bacillus axarquiensis were present in all the tissues of both the genotypes of pearl millet. However, most of the other endophytic bacteria showed tissue/genotype specificity. With the exception of B. axarquiensis and B. thuringiensis, rest all the species of Bacillus were found colonizing only the drought-tolerant genotype; while M. caseolyticus colonized all the tissues of only the drought susceptible genotype. There was high incidence of IAA producers and low incidence of ACC deaminase producers among the isolates from the root tissues of the drought-tolerant genotype while reverse was the case for the drought-susceptible genotype. Thus, host played an important role in the selection of endophytes based on both phylogenetic and functional traits.

RESUMO

This study was conducted to develop simple superovulation protocols in dromedary camels. Using two commercial FSH products, a series of experiments was conducted to evaluate the effect of different superovulation protocols on ovarian response and embryo production. In experiment 1, camels in control group (n = 15) received 400 mg Folltropin-V in a traditional protocol (FSH diluted in saline and given twice daily in decreasing doses over 5 days) and camels in split-injection (2 doses 48 h apart) groups received either 400 (n = 16, first dose: 320 mg, second dose: 80 mg) or 200 mg (n = 16, first dose: 120 mg, second dose: 80 mg) of slow-release (SR) preparation of Folltropin-V [Folltropin-V diluted in hyaluronan (5 mg/mL) solution]. In experiment 2, camels in control group (n = 13) received 2000 IU Pluset in a traditional protocol and camels in split-injection groups received either 2000 (n = 14, first dose: 1600 IU, second dose: 400 IU) or 1000 IU (n = 16, first dose: 600 IU, second dose: 400 IU) of SR preparation of Pluset (Pluset diluted in hyaluronan solution). In experiment 3, camels received SR preparation of 200 mg Folltropin-V (n = 45, first dose: 120 mg, second dose: 80 mg) or 1000 IU Pluset (n = 42, first dose: 600 IU, second dose: 400 IU) in a split-injection protocol. In experiments 1 and 2, the mean number of ovulations, corpora lutea, transferable embryos and unfertilized ova were similar (P > 0.05) between groups. In experiment 3, there was no difference (P > 0.05) between SR preparations of Folltropin and Pluset on the number of ovulatory sized (≥9 mm) follicles (15.8 ±â€¯0.9 vs 16.7 ±â€¯0.9) and transferable embryos (5.0 ±â€¯0.4 vs 5.2 ±â€¯0.5). In conclusion, split-injection of SR preparation of FSH resulted in a similar superovulatory response compared to a traditional protocol and a similar superovulatory response can be achieved with SR preparations of Folltropin-V and Pluset in a split-injection protocol.

RESUMO

INTRODUCTION: The Indian National Mental Health Survey (NMHS) of 2015-2016 has estimated 13.7% lifetime and 10.6% point prevalence for mental illnesses. It has identified that the treatment gap for mental illnesses ranges between 70% and 92%. Tele-Psychiatric consultations could be an alternative and innovative approach to bridge this gap in low resource settings. AIMS: To study the sociodemographic and clinical profiles of patients who have received collaborative Tele-Psychiatric consultations across district hospitals in Karnataka, India. METHODOLOGY: We performed a retrospective review of case files of patients who have received collaborative Tele-Psychiatric consultations from January 2013 to June 2017 through video-conferencing. A total of 139 consultations were provided to patients in the state of Karnataka. RESULTS: The mean age of the sample is 31 (±15.5) years. 61.8% were male and 79.8% were aged more than 18 years. In total, 25.9% of them had schizophrenia and other psychotic disorders, 14.4% had mental retardation, 13.7% had a mood disorder and 14.4% had a substance use disorder. 67.6% of patients had been advised pharmacotherapy, 7.9% had been advised rehabilitation along with pharmacotherapy and 24.4% were advised further evaluation of illness and inpatient care at a higher centre. CONCLUSION: Collaborative tele-psychiatric consultations to district hospitals from an academic tertiary care hospital can be feasible and are likely to benefit patients from rural areas. There is a need for more studies to elucidate their acceptability by patients, caregivers and professionals.

RESUMO

BACKGROUND: Neurological rehabilitation service in developing countries like India is a great challenge in view of limited resources and manpower. Currently, neurological rehabilitation with a multidisciplinary team is limited to a few major cities in the country. Tele-neurorehabilitation (TNR) is considered as an alternative and innovative approach in health care. It connects the needy patients with the health-care providers with minimum inconvenience and yields cost-effective health care. AIM: The aim of this study was to study the socioclinical parameters, feasibility, and utility of TNR services in India. METHODOLOGY: A retrospective file review of TNR consultations provided through Telemedicine Center at a quaternary hospital-based research center in south India between August 2012 and January 2016. RESULTS: A total of 37 consultations were provided to the patients belonging to four districts of Karnataka. The mean age of the patients was 34.7 (±19.5) years, 23 (62.1%) were aged between 19 and 60 years, and 31 (83.8%) were male. Thirty-one patients (83.8%) had central nervous system-related disorders such as stroke, cerebral palsy, and tubercular meningitis with sequelae or neuromuscular disorders such as Guillain-Barre Syndrome and Duchenne muscular dystrophy. Twelve patients (32.4%) were advised to consult higher centers in the vicinity, and the rest was referred to the district hospital. CONCLUSION: The findings suggest that TNR services are feasible, effective, and less resource intensive in delivering quality telemedicine care in India. More clinical studies are required to elucidate its full utility at different levels and in different parts of the country.
