Role of Dietary Management and Physical Activity in Control of Hypertension in Rural Areas of Punjab-A Cross-sectional Study

Introduction: As reported by WHO, hypertension is the third ‘killer’ disease, accounting for one in every eight deaths worldwide. Many modifiable and non-modifiable risk factors are found to be associated with the disease. The present study aims to determine the role of dietary management and physical activity in the control of hypertension in a given population. Material and Methods: A cross-sectional study was conducted that. Study included all hypertensive patients (290) from the field practice area of a tertiary care institute. A self-constructed, pretested questionnaire was used to enquire about the socio- demographic factors and other risk factors associated with hypertension. The data was analyzed using SPSS 23 and valid conclusions were drawn by using the chi-square test. Results: Out of 290 patients, 204 (70.3%) were females and 86 (29.7%) were males. Univariate analysis identified decreased salt intake, decreased fatty food consumption, physical activity, stress management, and spiritual help as highly significant factors affecting hypertension. On multivariate analysis, physical activity, stress management and spiritual help were found to be significant. Conclusion: The study showed that physical activity, stress management and spiritual help were significantly associated with hypertension control among the elderly. Measures should be taken to create awareness about lifestyle modifications in the control of hypertension.

A study of knowledge, attitude and practices regarding biomedical waste management among health care providers in a tertiary care Institute in Punjab

The biomedical waste, if not properly managed, can harm the surrounding environment, cause various infections and injuries to the healthcare workers, patients, their attendants. Methods: This cross-sectional study was conducted to assess the knowledge, attitude and practices among different cadres of health care providers in a tertiary care institute. Expecting that 50% of the study population had precise knowledge about the rules and legislation of biomedical waste management, with an allowable error of 10%, at 95% confidence interval, and accounting for the finite population correction for 1700 participants, a minimum sample size of 426 was taken. Data analysis was done by using Microsoft excel and SPSS. Results: Out of 426 subjects, 138 (32.4%) were nurses, 35 (8.2%) were lab technicians and 253 (59.4%) were housekeeping staff. Knowledge, attitude and practices regarding biomedical waste management and handling were significantly (p<0.05) higher among the nurses as compared to other health care providers. Conclusions: Knowledge, attitude and practices regarding the collection, segregation, rules, and disposal of biomedical waste management was more among nursing staff compared to other health care workers. Hence, emphasis on adequate training is required among other health care workers for the safe handling and disposal of biomedical waste management.

Direct Benefit Transfer Scheme for Tuberculosis Patients – Performance Challenges observed by the Providers and Patients

Introduction: Government of India launched an Aadhar-linked Direct Benefit Transfer (DBT) scheme from 1st April, 2018. Under this scheme, all notified TB patients would receive Rs 500 per month (~US$7) throughout the course of their treatment for nutritional support. Aim and Objectives: To determine the challenges faced by the health providers and patients in the implementation of Direct Benefit Transfer scheme. Methods: This was a mixed method cross-sectional study conducted on all public and private TB patients notified during the year 2019 under RNTCP (now NTEP) in district Amritsar, Punjab. Quantitative data about the availability and validation of bank accounts was obtained from the Nikshay portal after having permission from the District TB Officer. Qualitative data was obtained from the focus group discussion and in-depth interviews with the involved staff members (17) and patients (20) registered in Tuberculin units of Amritsar. Results: From the Nikshay reports, it was observed that there was significant difference between the public and private sector and between rural and urban areas. Focus group discussion was done with the TB Health Visitor (TBHV) and Senior TB supervisors (STS) and asked about the hurdles they faced. Items were identified and tabulated. In-depth interviews were conducted on 20 patients, 10 each from public and private sector respectively. Data collected was transcribed and arranged as per the themes or questions and then the information was recorded under those sub-headings. Conclusion: The major challenges observed by the providers were lack of support from the private sector, lack of awareness among people, technical issues and more work burden. Patients mostly mentioned about confidentiality issues, lack of awareness, social stigma of the disease, less amount and long and complex process.

Correlation of optical coherence tomography angiography and microperimetry (MP3) features in wet age-related macular degeneration

Purpose: To evaluate and correlate the functional treatment response using microperimetry (MP3) with the morphological findings on optical coherence tomography angiography (OCTA) in wet AMD pre- and post-treatment with anti-vascular endothelial growth factor (VEGF). This was a single-centre prospective, interventional study. Methods: Patients with wet AMD were treated with 3 injections of intravitreal anti-VEGF at monthly intervals for 3 months and followed at 1, 2, 3, and 6 months postinjection. Using “overlay” features, morphologic characteristics of OCTA at the site of choroidal neovascular membrane (CNVM) lesion were analyzed and correlated functionally with MP3. Data were collected including visual acuity at presentation and follow-up with multimodal imaging features, treatment details, complications (if any), and treatment given for that complication. Descriptive observational analysis and paired t-test was used to compare the appearance of the neovascular network on OCTA imaging with retinal sensitivity on MP3. Results: OCTA in the pretreatment phase revealed CNVM as an abnormal vascular network arising from the choroid and invading the subretinal space. On MP3, decreased retinal sensitivity was observed corresponding to the area of CNVM. Post-treatment, OCTA revealed reduction in abnormal vascular network in 51 (91.07%) eyes that correlated with increased retinal sensitivity at the corresponding area on MP3. Statistical analysis showed baseline mean retinal sensitivity at the site of CNVM as 320.07 dB, which improved to 521.53 and 730.20 dB at 1 and 3 months postinjection follow-up, respectively. Conclusion: Combining the findings of OCTA and MP3 using “overlay” features gives us precise information of structure–function correlation at presentation and also in response to treatment. It also helps to improve patient's compliance, confidence to treatment, and their understanding of the disease process as well.

Management of recurrent rhegmatogenous retinal detachment

Rhegmatogenous retinal detachment (RRD) repair is one of the most common vitreoretinal surgeries a surgeon performs. In an ideal scenario, RRD can be repaired with a single surgical intervention; however, despite excellent skill, flawless technique, and the introduction of high-end technology, up to 10% of cases require additional interventions to ultimately repair recurrent detachments. It is thus important to study the outcomes of multiple interventions to understand whether performing repeat vitrectomy on patients with a history of failed surgeries is worthwhile. Thus, recurrent retinal detachment (re-RD) remains a significant challenge for vitreoretinal surgeons as well as the patients considering the economic and the emotional burden of undergoing multiple interventions. The advent of microincision vitrectomy system, perfluorocarbon liquids, and effective intraocular tamponades has opened new doors for managing re-RDs. In this article, we have reviewed and summarized the various causes and approaches for management for optimal anatomical and functional outcomes.

Branch retinal artery occlusion post-penetrating globe injury with intraocular foreign body

Intraocular foreign body (IOFB) in cases of penetrating eye injury accounts for an important indication of vitreoretinal intervention following ocular trauma. Vascular occlusion as a complication of IOFB is rare. Here we present a case of a 34-year-old male with post-traumatic cataract and an intraocular metallic foreign body (IOFB) lodged in the superficial layers of the retina inferotemporal to the disc, causing an inferotemporal branch retinal artery occlusion. The case was managed by lensectomy with pars plana vitrectomy and IOFB removal followed by a second procedure of secondary IOL implantation. Final best-corrected visual acuity improved to 6/24. This case highlights an unusual sequelae following penetrating ocular trauma.
