Impact of the COVID-19-induced lockdown on the incidence of ocular trauma presenting to a tertiary care hospital.

Objective: To assess the effects of lockdown and unlock phases mandated in view of COVID-19 on the incidence and characteristics of ocular trauma presenting to a tertiary care hospital. Methods and Analysis: The study was carried out as a hospital record based retrospective comparative analysis on patients presenting with ocular trauma in the lockdown period (March-July 2020) compared with the same time frame of the previous year considered as prelockdown period (March-July 2019) and during the unlock phases (August-December 2020). Results: Overall, the casualty department saw 464 patients of ocular trauma in the prelockdown period, 173 in the lockdown and 253 in unlock. The study showed a 44% reduction in patients visiting the casualty department for trauma during the lockdown compared with prelockdown, and a 62% reduction specifically in ocular trauma. The unlock phase showed a 21% reduction in ocular trauma compared with prelockdown and a 41% increase compared with the lockdown. In all three phases, the majority of people affected by ocular trauma were middle aged males from a rural background, sustained by assault. The lockdown saw a decrease in outdoor assaults (45%) and road traffic accidents (22%). Trauma sustained by females (18%) increased in the lockdown, as did home-based assaults (150%) and sexual assaults. The presentation of trauma, especially road traffic accidents and outdoor assaults saw a steady rise during the unlock. Conclusion: The lockdown mandated by the government in response to the COVID-19 pandemic had a significant impact on the trends of trauma presenting to healthcare facilities. There was a decrease in the overall number of patients approaching the casualty during the lockdown. However, during the lockdown, there was an increase in home-based trauma as opposed to outdoor assaults being the primary cause of trauma prior to the lockdown.

Study of ocular manifestations in tuberculosis and its association with HIV AIDS in a tertiary care hospital.

OBJECTIVE: To assess and understand the prevalence and clinical presentation of ocular morbidity in patients suffering from tuberculosis and compare it with ocular involvement in patients coinfected with tuberculosis and HIV AIDS. MATERIALS AND METHODS: This was a non-comparative, observational, cross sectional study done on 580 patients, who were diagnosed cases of tuberculosis, pulmonary or extrapulmonary, on or off treatment, visiting the Ophthalmology OPD, Tuberculosis OPD and ART Centre of the institute in the period from March 2015 to March 2018, screened for ocular morbidity. RESULTS: Out of 580, 408 patients had only tuberculosis and 172 had tuberculosis with HIV AIDS. 108 patients were found to have ocular involvement (18.6%) out of which 63 were males and 45 were females. The prevalence of ocular morbidity in patients with only tuberculosis was found to be 16.4% and in those having both tuberculosis and HIV AIDS was found to be 23.8%. CONCLUSION: Our study concludes that posterior uveitis, pan uveitis, periphlebitis and vitritis are the most common ocular manifestations in tuberculosis. In patients with both tuberculosis and HIV most common ocular findings included vitritis and herpes zoster ophthalmicus. Our study also concludes that lower CD4 counts (less than 200) in HIV AIDS patient is significantly associated with ocular involvement.

Fourier Transform Near-Infrared Spectroscopy for rapid and simple determination of phytic acid content in green gram seeds (Vigna radiata).

The feasibility of measuring phytic acid content in green gram (Vigna radiata) seeds was investigated by Fourier Transform Near-Infrared (FT-NIR) spectroscopic technique. Pure phytic acid standards of varying concentrations were scanned using FTNIR spectroscopy. The spectra were measured in diffused reflectance mode by keeping 100-1500 mg/100g standard of pure phytic acid in small sample cuvette. A calibration model was developed using pure phytic acid standards of varying concentrations in the near-infrared region (4000-12,000 cm(-1)). FT-NIR spectroscopy with chemometrics, using the first derivative plus vector normalisation method could predict the phytic acid content in green gram seeds samples. The developed model was validated using cross-validation technique. Maximum coefficient of determination (R(2)) value of 0.97 was obtained for the calibration model developed. The developed model was applied to predict phytic acid content in green gram seeds samples within 1-2 min. The developed procedure was further validated by recovery studies by comparing with UV spectroscopic method of phytic acid determination.

Microwave drying for safe storage and improved nutritional quality of green gram seed (Vigna radiata).

The present study describes the effect of the microwave-heating method on disinfestations and physico characteristics, viz., grain size, grain hardness, and nutritional quality, of the stored green gram seed. It has been observed that the use of the microwave-heating method not only prolongs the storage duration of the green gram seed but also enhances its nutritional quality. The effect of independent parameters, viz., microwave power level and time of exposure, on the moisture content, insect mortality, color, and antinutrient factor (phyic acid) was optimized using response surface methodology (RSM), with the optimized value for power of 808 W and time at 80 s. The optimally treated green gram seed has 8.9% moisture, 99.5% insect mortality, 2.22 Δa* (green color of seed), and 591.79 mg/100 g of antinutrient factor (phytic acid). The grain size (geometric mean diameter, D(m)) of the control (untreated) sample was 3.75 mm, and that of the microwave-treated sample using optimum conditions was 3.99 mm. The grain hardness of the control sample was 3.31 kg, and that of the microwave-treated sample using optimum conditions was 1.305 kg. In vitro protein digestibility (IVPD) of the control (untreated) sample was 83 ± 0.289%, and that of the microwave-treated sample using optimum conditions was 85 ± 0.296%. These values are significantly difference (p < 0.05). The mineral elements studied were Zn, Fe, Mg, Mn, Cu, K, Ca, and Na. The microwave treatment resulted in a non-significant (p < 0.05) effect for Mg, Mn, Cu, K, and Na but a significant (p < 0.05) effect for Zn, Ca, and Fe. The results indicate that the microwave heating not only increases the insect mortality but also reduces the moisture content and antinutritional factor (phytic acid), while the natural green color of the seed is not affected much. This study provides a novel and environmentally safe technique and increase in the nutritive quality.
