RESUMO

Background-Oxidative stress in biological systems is a complex process that is characterized by an inequity between the production of free radicals (FR) and the ability of the body to eliminate these reactive species through the use of endogenous and exogenous antioxidants. The pathogenesis of oral cancer has been linked to alterations in the antioxidant defense mechanism. Materials & Methods- Saliva from twenty patients with OSCC, forty patients with OPMDs and twenty healthy subjects in the age group of thirty five to seventy five years was analyzed for levels of nitric oxide, vitamin C, total sialic acid and GSH using spectrophotometry. Results - The levels of salivary vitamin C and glutathione were significantly reduced and those of nitric oxide and sialic acid were raised in patients having OPMD's and oral squamous cell carcinoma. The co- relation between the AOI and calculated ratios indicated that antioxidant potential of the saliva was decreased and was statistically related to (p <0.001) development of OPMD, which further may progress to oral cancer, notably OSCC. Conclusion- The current study demonstrated that the estimation of vitamin C, nitric oxide, sialic acid and GSH in saliva could be used as an early potential diagnostic biomarker in the screening of oral cancer. The antioxidant-oxidant indices (AOI's) can be used as a reliable tool for predicting the oral microenvironment and its predicted change towards development of oral cancer. This optimized developed protocol was also found to be simple and cost effective.

RESUMO

Introduction: In developed countries, about 50% of all Low-Birth-Weight new born are preterm. Low birth weight is also a leading cause of neonatal death and major risk factor for infant and under-five morbidity and mortality. Objectives: To find out prevalence of low birth weight& to determine the association of socio-demographic variables, maternal medical and obstetric risk factors with low birth weight. Methodology: Across sectional community-based study was conducted in a rural field practice area of a medical college. A total of 600 participants (mothers who delivered within 3 months) were included in the study. Results: The prevalence of LBW was found to be 17% in the current study. Statistically significant asso-ciation was obtained between age, education, occupation, socio-economic class of participants and birth weight of the child. The prevalence of LBW was found to be significantly high (51.7%) amongst children of those participants who consumed/used tobacco in any form. Conclusion: The prevalence of the LBW was found to be 17%. Extremes of reproductive age group, illit-eracy, occupation of labourer, SEC class IV, grand-multiparity, inadequate IFA consumption, short stat-ure, weight of mother and use of tobacco were found to be significantly affecting the birth weight and as-sociated with low birth weight.

RESUMO

Background: Abnormal Uterine Bleeding (AUB) is a very frequent cause of gynecological visits in women of all age groups. Ultrasound pelvis with or without endometrial sampling have been conventionally used to make diagnosis. Power Doppler is a comparatively recent modality which can be used to screen patients who will need endometrial biopsy/ curretage. We hereby conducted a study to compare the diagnostic accuracy of power Doppler sonography and hysteroscopy with histopathology associated with abnormal uterine bleeding. We also calculated the incidence of uterine pathology in AUB by power Doppler ultrasound and hysteroscopy and compared it with histopathology. Methods: This prospective cohort study was conducted at the Department of Obstetrics and Gynaecology, Institute of Medical Sciences, Banaras Hindu University. After excluding 42 women, a total of 100 women fulfilling the inclusion criteria contributed to our study. Selected women underwent power Doppler ultrasound and hysteroscopy with guided biopsy. Results were compared with histopathology as per the gold standard. Evaluation of sensitivity, specificity, positive and negative predictive values were performed for each modality. All statistical analyses were performed using the SPSS 11.0 statistical package. P value ?0.05 was considered statistically significant for all tests used. Results: Sensitivity and specificity of power Doppler are 75% and 100% for carcinoma endometrium, 72.72% and 98.9% for endometrial hyperplasia, and 81.81% and 100% for endometrial polyp, respectively. Conclusion: Power Doppler sonography can be used to screen outpatients who do not need an endometrial biopsy for abnormal uterine bleeding. This will avoid unnecessary hysteroscopy in definitive benign cases, and watchful hysteroscopy in suspected premalignant and malignant cases. Irregular branching vessels and color splashes were found to be the best parameters for diagnosing endometrial carcinoma. Power Doppler should be done along with transvaginal sonography in all cases of abnormal uterine bleeding

RESUMO

Purpose: To evaluate the frequency and the association of Thrombospondin 1 (THBS1) gene single nucleotide polymorphisms (SNPs) in Asian Indian patients with optical full thickness corneal grafting surgery. Methods: Prospective case朿ontrol analysis of optical penetrating keratoplasty patients with and without immune rejection and controls for genotyping of 3 THBS1 gene SNPs (rs1478604 A>G; rs2228261 C>T; rs2228262 A>G) by Amplification Refractory Mutation System-Polymerase Chain Reaction (ARMS PCR). Results: Among 58 patients [45 with immune allograft rejection (DNA isolation was possible in 38 samples) and 13 without immune corneal allograft rejection] and 65 controls, allele frequencies observed for rs1478604 (A>G) are A: 69.7% and 72.6%, G: 30.2% and 27.3%; for rs2228261 (C>T) are T: 70.2% and 62.3%, C: 29.7% and 37.6%; and for rs2228262 (A>G) A: 97.4% and 98.4%; G 2.5% and 1.5% respectively. Genotype frequencies were rs1478604 (A>G) AA: 57.8% and 59.3%, AG 23.6% and 26.5%; GG 18.4% and 14%; for rs2228261 (C>T) TT: 40.5% and 33.8%, TC: 59% and 56.9%, CC: 0% and 9.2%; for rs2228262 (A>G) AA: 94.8% and 96.8%, AG: 5.1% and 3.1% in rejection and controls respectively. The allele and genotype frequency for the 3 described THSB1 SNPs did not show any difference between the corneal graft immune rejection patients and controls. Conclusion: Asian Indian population evaluated for THBS1 gene SNPs by ARMS PCR genotyping in Asian Indian population did not show any genetic association to immune rejection occurrence in our study.

RESUMO

Purpose: To assess the proportion of people with type 2 diabetes mellitus (T2DM) with diabetic retinopathy (DR) and sight-threatening DR (STDR) and associated risk factors in select eye-care facilities across India. Methods: In this observational study, data of people with T2DM presenting for the first time at the retina clinic of eye-care facilities across India was recorded. Data collected in 2016 over 6 months included information on systemic, clinical, and ocular parameters. International Clinical Diabetic Retinopathy (ICDR) classification scale was used to grade DR. STDR was defined as presence of severe nonproliferative (NPDR), proliferative diabetic retinopathy (PDR), and/or diabetic macular edema (DME). Results: The analysis included 11,182 people with T2DM from 14 eye-care facilities (mean age 58.2 ± 10.6 years; mean duration of diabetes 9.1 ± 7.6 years; 59.2% male). The age-standardized proportion of DR was 32.3% (95%Confidence Interval, CI: 31.4-33.2) and STDR was 19.1% (95%CI: 18.4-19.8). DME was diagnosed in 9.1% (95%CI: 8.5-9.6) and 10.7% (95%CI: 10.1-11.3) people had PDR. Statistically significant factors associated with increased risk of DR (by multivariate logistic regression analysis) were: male gender (Odds ratio[OR] 1.57, 95%CI: 1.16-2.15); poor glycemic control–glycated hemoglobin (HbA1c >10%)(OR 2.39, 95% CI: 1.1-5.22); requirement of insulin (OR 2.55, 95%CI: 1.8-3.6);history of hypertension (OR 1.42, 95%CI: 1.06-1.88) and duration of diabetes >15 years (OR 5.25, 95%CI: 3.01-9.15). Conclusion: Diabetic retinopathy was prevalent in 1/3rd and sight-threatening DR in 1/5th of people with T2DM presenting at eye-care facilities in this pan-India facility-based study. The duration of diabetes was the strongest predictor for retinopathy.

RESUMO

Purpose: To document the spectrum of eye diseases in people with type 2 diabetes mellitus (T2DM) reporting to large eye care facilities in India. Methods: The selection of eye care facilities was based on the zone of the country and robustness of the programs. Only people with known T2DM certified by internist, or taking antidiabetes medications, or referred for diabetes related eye diseases were recruited. The analysis included the demographic characteristics, systemic associations, ocular comorbidities, and visual status. Results: People (11,182) with T2DM were recruited in 14 eye care facilities (3 in north, 2 in south central, 4 in south, 2 in west, and 3 in east zone); two were government and 12 were non-government facilities. Hypertension was the commonest systemic association (n = 5500; 49.2%). Diabetic retinopathy (n = 3611; 32.3%) and lens opacities (n = 6407; 57.3%) were the common ocular disorders. One-fifth of eyes (n = 2077; 20.4%) were pseudophakic; 547 (5.4%) eyes had glaucoma and 277 (2.5%) eyes had retinal vascular occlusion. At presentation, 4.5% (n = 502) were blind (visual acuity <3/60 in the better eye) and 9.6% (n = 1077) had moderate to severe visual impairment (visual acuity <6/18-->3/60 in the better eye). Conclusion: People with T2DM presenting at eye clinics in India have high rates of diabetic retinopathy and vision loss. Cataract is a very common occurrence. Advocacy, infrastructure strengthening, and human resource development are the key to address the growing threats of T2DM and eye care in India.

RESUMO

Purpose: Diabetes is a public health concern in India and diabetic retinopathy (DR) is an emerging cause of visual impairment and blindness. Approximately 3.35–4.55 million people with diabetes mellitus (PwDM) are at risk of vision-threatening DR (VTDR) in India. More than 2/3 of India's population resides in rural areas where penetration of modern medicine is mostly limited to the government public health system. Despite the increasing magnitude, there is no systematic screening for the complications of diabetes, including DR in the public health system. Therefore, a pilot project was initiated with the major objectives of management of DR at all levels of the government health system, initiating a comprehensive program for the detection of eye complications among PwDM at public health noncommunicable disease (NCD) clinics, augmenting the capacity of physicians, ophthalmologists and health support personnel and empowering carers/PwDM to control the risk of DR through increased awareness and self-management. Methods: A national task force (NTF) was constituted to oversee policy formulation and provide strategic direction. 10 districts were identified for implementation across 10 states. Protocols were developed to help implement training and service delivery. Results: Overall, 66,455 PwDM were screened and DR was detected in 16.2% (10,765) while VTDR was detected in 7.5%. 10.1% of those initially screened returned for the next annual assessment. There was a 7-fold increase in the number of PwDM screened and a 7.6-fold increase in the number of PwDM treated between 2016 and 2018. Conclusion: Services for detecting and managing DR can be successfully integrated into the existing public health system.

RESUMO

India has the highest number of preterm births in the world, which along with low birth weight, are significant risk factors for retinopathy of prematurity (ROP). One of the challenges in combating visual loss from ROP is the lack of information and awareness among parents of preterm babies. The objective of establishing ROP parent support groups was to support parents of children with ROP by counseling, information and resource sharing, and general guidance. As part of a major initiative to combat ROP across four states in India, a strategy to develop parent support groups was developed and a pilot project was implemented in three cities. In collaboration with identified eye institutes, five ROP parent support group sessions were conducted in these cities. The concept is still in its initial stages of implementation and data are not yet available on the impact of the support groups. However, the overall turnout for the meetings was low as only 30% of parents invited attended meetings. Initial learning and experiences suggest that parent support groups could have a significant role to play in providing many benefits especially in improving awareness, knowledge, and compliance, alleviating anxiety, and empowering parents.

RESUMO

The outcome of a retinopathy of prematurity (ROP) program initiated in five districts of Odisha over 3 years with partnerships between the government and non-government organizations was prospectively analyzed. The mentoring partners trained the district ophthalmologists and neonatal care providers; the program was handed over when the trainees were considered competent enough to diagnose and treat babies with ROP. During the project period (July 2016–June 2019), 3058 babies were examined; ROP was detected in 33.81% (n = 1034) and 5.06% (n = 159) babies required treatment. At the end of the project, ROP screening was possible in all five districts, and treatment was possible in three districts. ROP care nodal centers were built in one government medical college. To strengthen the initial gain, we recommend creating an Odisha Retinopathy of Prematurity (OD-ROP) steering committee with private–public partnerships to support the program and monitor its progress in other districts of Odisha.

RESUMO

Purpose: With improving survival of preterm neonates, retinopathy of prematurity (ROP) is emerging as a major cause of childhood blindness. Incidence of sight-threatening ROP can be reduced by improving the quality of care provided to preterm neonates. Methods: This before-and-after study was designed to develop a need-based intervention package to improve knowledge, skills, and practices of those providing care for preterm neonates, and to evaluate the effectiveness of this package when combined with point-of-care quality improvement (POCQI) in improving survival of preterm neonates without sight-threatening ROP. The study had a formative component to assess baseline knowledge, skills, practices and attitudes, and to assess the needs of the healthcare staff to improve the care of preterm neonates. It was conducted in four special care neonatal units (SCNU) in the state of Madhya Pradesh in India. Results: A theory of change was developed to guide the development of study tools including needs assessment and educational package development. The educational package thus developed has been tested at the study sites in combination with POCQI projects driven by local teams of healthcare providers. The effectiveness of the interventions has been evaluated by collection of individual-level data on neonates admitted at the study sites. Conclusion: A multidimensional educational package integrated with system changes in the form of quality improvement (QI) endeavours driven by local context and needs were developed and evaluated in the project.

RESUMO

Retinopathy of Prematurity (ROP) is a potentially blinding disease of the eye that can affect infants born four or more weeks preterm and have received intensive neonatal care. ROP is a dynamic, time-bound disease that is not present at birth. Preventing visual loss from ROP in India requires scaling up services for screening and treatment for ROP to match the exponential growth in neonatal intensive care in India and other low- and middle-income countries. Operational guidelines for prevention of visual loss from ROP will facilitate rapid scale up of services, by identifying key players and their roles and responsibility in the Indian context. The guidelines recommend broad eligibility criteria for screening (gestational age ?34 weeks, birth weight ?2000 gms) as the special newborn care unit (SNCU) have varying quality of neonatal care. Treatment is based on the early treatment for retinopathy of prematurity (ET-ROP) study treatment criteria. The screening criteria could be revisited when more contextual evidence on the risk of ROP is available in India.

RESUMO

Purpose: In India, more than 800 special newborn care units (SNCUs) have been established since 2008 in government facilities. More preterm infants are now surviving and blindness from retinopathy of prematurity (ROP) is increasing. The aim of the Queen Elizabeth Diamond Jubilee Trust's initiative (2012–1019) was to improve the quality of neonatal care and integrate ROP services into the government health system using expertise in the government and nongovernment sector in four states in a sustainable and scalable manner. Methods: State Ministries of Health were engaged and collaboration was established between three government programs (Ministry of Health and Family Welfare, Rashtriya Bal Swasthya Karyakram, and blindness prevention) and relevant professionals. Extensive training took place and equipment was provided. Implementation was guided by a multidisciplinary National Task Force and was monitored by state coordination committees. The Task Force appointed technical expert groups to support implementation through advocacy, information, education and communication materials, operational guidelines, a competency-based training curriculum, and an online database and website. Results: Twenty-two ophthalmologists in government facilities were trained to screen for ROP and nine to treat ROP. Almost 13,500 preterm infants were screened in 17 SNCUs and 86% of the 456 infants with sight-threatening ROP were treated. An educational resource using latest pedagogy based on key domain areas for best practices for small and preterm neonates including ROP has been developed and pilot tested and is being evaluated and scaled up. Conclusion: All four states are scaling up services or have plans to scale up, and several other states have started the initiatives.

RESUMO

People with diabetes mellitus require long-term care that is timely, patient-centered, community-based and sustainable. Any deficiency in care increases the risk of developing complications like Diabetic Retinopathy. Patients or their carers also have numerous questions and doubts during this long-period of care. This increases the pressure on health systems that are struggling with a lack of skilled human resources. One option is to provide counseling support using a dedicated helpline. Over the last five years a major initiative to tackle visual impairment due to diabetes was rolled out in India by the Public Health Foundation of India supported by the Queen Elizabeth Diamond Jubilee Trust, UK. One component of the initiative was establishing a toll-free helpline (1800 121 2096) to address the lack of awareness and to empower people with diabetes in Telangana and Andhra Pradesh states in India. Over a 1-year period, the helpline received 4406 calls, making a case for a national service for people with diabetes.

RESUMO

Diabetes mellitus continues to increase in epidemic proportions globally as well as in India. Poor glycemic control in long-standing diabetes mellitus eventually leads to chronic complications such as retinopathy, nephropathy, neuropathy, and cardiovascular disease. Diabetic retinopathy is emerging as an important cause of avoidable visual impairment and blindness in India across all strata of society. Much of this vision loss can be prevented by improving control of known risk factors, annual fundus screening, with prompt treatment of individuals with sight-threatening retinopathy. The Queen Elizabeth Diamond Jubilee Trust has made a significant contribution by supporting such a program across India, including Goa. The newly established medical retina clinic at Goa Medical College now provides facilities for screening, a detailed evaluation of advanced retinopathy, and therapeutic modalities such as laser and intravitreal injections. The peripheral centers are equipped to screen all people with diabetes mellitus and refer those with sight-threatening retinopathy to the medical college. The provision of a foot scanner to evaluate the risk of foot ulcers and microalbuminuria assessment as part of the nephropathy screening would encompass the entire gamut of diabetic microvascular complications. The next decade would provide evidence if this initiative, with the enthusiastic partnership of the state government, results in reduction of blindness in the people of Goa and an overall reduction in diabetes-related morbidity and mortality.

RESUMO

Purpose: Complications of diabetes mellitus (DM) are a public health problem globally. DM management entails medication and self-management. Peer support groups (PSGs) can improve self-management and promote healthy behavior. The objectives of this study were to design, establish, and evaluate two PSG models for people who had been screened for diabetic retinopathy to assess self-reported lifestyle changes, satisfaction with meetings and barriers to attendance. Methods: Peer groups were established using a pre-tested facilitator's guide in 11 locations in 3 states. Group members were oriented on diabetes management and lifestyle changes to improve control. Attendees' experiences were ascertained through semi-structured interviews and self-report. Data were analyzed using MS Excel 2017. Results: Eleven PSGs were established in 3 states, in 10 community health centers and one eye hospital. 53 sessions were held and 195 people attended on 740 occasions. Lifestyle changes most frequently reported between first and second visits were taking medication regularly and dietary modification. Attendance declined in the eye hospital group. 83% of CHCs members were satisfied or very satisfied compared with 37% of eye hospital (EH) members. The barriers included distance and lack of family support. Conclusion: PSGs held in CHCs were more sustainable than those in an eye hospital, and group members were more satisfied and more likely to report positive lifestyle changes. Findings were self-reported and hence a major limitation for the study. Further studies should focus on obtaining objective measures of control of diabetes and risk factors for diabetic retinopathy from members attending peer support groups in CHCs.

RESUMO

Diabetes mellitus (DM) is of increasing public health importance in India. The magnitude has been increasing over the past three decades. DM is associated with major microvascular complications among which diabetic retinopathy (DR) is emerging as one of the leading causes of visual impairment in low and middle income countries. Two-thirds of the Indian population resides in rural areas where access to modern medicine is limited mostly to the public health system. Operational guidelines are critical in delivering program components effectively. They provide the template to benchmark service delivery and help in improving quality of care. A pilot initiative to reduce visual impairment in people with diabetes was supported by an international nongovernmental funding organization over a 5-year period in India. This initiative facilitated the development of operational guidelines for DR. The guidelines were developed through consensus and primarily addressed the public health system in India.

RESUMO

Purpose: In India, people with diabetes (PwDM) often seek care in the government-approved alternative medicine system, AYUSH (Ayurveda, Yoga and naturopathy, Unani, Siddha and Homeopathy). The purpose of this pilot study was to assess whether health education plus retinal imaging for diabetic retinopathy (DR) within an AYUSH hospital increased the uptake of screening for DR compared with health education and referral. Methods: The study was a nonrandomized pilot conducted in two AYUSH hospitals. Both hospitals received intervention on educating the AYUSH practitioners about DR screening and distributing health education materials to diabetic patients. In one hospital in addition to education, retinal imaging by a trained technician with remote grading by an ophthalmologist was provided, while in another hospital PwDM were referred to nearby eye hospitals for screening. The uptake of screening was assessed through registers and phone calls. Results: At baseline, only 10.7% of 178 PwDM were aware of DR and only 8% had undergone DR screening. After the intervention, in the hospital where screening was provided, all (100%) eligible patients (101) underwent digital imaging, whereas in the other hospital only 25% of 77 eligible patients underwent screening in eye hospitals (P < 0.001). Conclusion: AYUSH hospitals could provide a feasible and acceptable location for providing DR screening services. Further studies are required to assess scale-up of such intervention.

RESUMO

Purpose: The effectiveness of Accredited Social Health Activists (ASHAs) with and without monetary incentive in uptake of diabetic retinopathy (DR) screening at community health center (CHC) was compared in South Gujarat, India. Methods: In this non-randomized controlled trial, ASHAs were incentivized to refer people with diabetes mellitus (PwDM) from their respective villages for DR screening after people were sensitized to DM and DR. The minimum sample size was 63 people in each arm. Results: Of 162, 50.6% were females, 80.2% were literate, 56.2% were >50 years, 54.3% had increased random blood sugar (RBS), and 59.9% had diabetes for 5 years. The percentage of screening was significantly higher [relative risk (RR) = 4.37, 95% confidence interval (CI) 2.79, 6.84] in ASHA incentive group and health education (HE) group (RR = 3.67, 95% CI 2.35, 5.75) compared with baseline. Providing incentive to ASHAs was not found to be of extra advantage (RR = 1.19, 95% CI 0.89, 1.57). The likelihood of uptake of screening was higher among uncontrolled PwDM, poor literacy, and higher duration of diabetes in incentive phase (P < 0.001) compared with HE. The results show that age (P = 0.017), education (P = 0.015) and level of RBS (P = 0.001) of those referred were significantly associated with incentives to ASHAs. Conclusion: ASHAs can be used effectively to refer known PwDM for DR screening especially when DR screening program is introduced in population with low awareness and poor accessibility. When incentives are planned, additional burden on resources should be kept in mind before adapting this model of care.

RESUMO

Purpose: The aim of this diagnostic observational study was to assess the spread and biological behavior of gallbladder cancer using 64-slice computerized tomography (CT) scanner in this particular geographic belt (eastern Uttar Pradesh, western Bihar, and northern Madhya Pradesh provinces of North India). Indians are ethnically and culturally different from their Western counterparts among whom the incidence of this disease is comparatively low. Subjects and Methods: After systemic examination, all patients (87) were subjected to ultrasonographic examination. All cases were histopathologically proven. Confirmed cases were subjected to volumetric CT examination of abdomen and pelvis, plain, post contrast and delayed phase. Results: Majority of the cases were adenocarcinoma. There was female preponderance with majority belonging to fifth and sixth decades. Commonest presentation was diffuse, irregular, enhancing wall thickening in 49.4%. Majority had invasion of liver parenchyma (74.7%). Cholelithiasis was seen in 48.3% cases. Invasion of biliary radicals was high (13.8-18.4%). Eleven cases had invasion of portal vein and tumor thrombus, with hepatic artery invasion in one case. In two cases, both hepatic artery and portal vein invasion was seen. Portal and peripancreatic nodal metastasis was seen in 58.5%. Distant metastasis was reported. Conclusion: Few studies involving the Indian population have attempted to use multi-row detector CT to define the biological behavior of carcinoma gallbladder. The opinion whether the pathology is operable or non-operable can reasonably be given. This large-scale, single-center study gives insight about the epidemiology and biological behavior of carcinoma gallbladder.
