Effect of vacuum and atmospheric frying and heating on physico-chemical properties of rice bran oil.

The study highlights the impact of vacuum (13.33 kPa) and atmospheric (101.325 kPa) pressure on the Physico-chemical stability of rice bran oil (RBO) during continuous frying and heating at equivalent thermal driving force (∆T = 45 °C). Reduced operating pressure played a major role in retaining the Physico-chemical quality of RBO. Results show that the PV, FFA, p-An value, IV, TOTOX value, total polar compound (TPC), saturated fatty acids, CIE color values, and viscosity of RBO increased significantly (p < 0.05) at a higher rate during frying and heating (22.24 h) under atmospheric pressure as compared to vacuum pressure. TPC and total saturated fatty acids were formed 34.37% and 32.76%, and 7.33% and 2.23% more, respectively, whereas, total unsaturated fatty acids were found to be 3.34% and 1.04% less during frying and heating at atmospheric pressure as compared to vacuum pressure condition. In general, vacuum frying technology is suitable for making papaya chips with extended reuse of RBO.

Sustaining immediate newborn care processes (delayed cord clamping and early breastfeeding initiation) in the delivery room: a quality improvement study.

BACKGROUND: Immediate newborn care processes like delayed cord clamping (DCC) and early breastfeeding initiation (EBFI) in the delivery room have several benefits including survival. Despite the evidence, the practices have not been widely adopted. We used a point-of-care quality improvement (QI) to implement and sustain these two immediate newborn care processes in our delivery room over a period of 2 years through a series of plan-do-study-act (PDSA) cycles. METHODS: All neonates above 30 weeks of gestation irrespective of the need for resuscitation except Rh-isoimmunisation were eligible for DCC. Neonates >35 weeks not requiring respiratory support or resuscitation were eligible for EBFI. The root causes of gaps in the quality were analysed by fishbone analysis. The key quantitative outcome measure was the percentage of eligible deliveries in which DCC and EBFI were done. Duration of DCC was also recorded in the sustenance phase. This implementation was done through three PDSA cycles and the practices were sustained for 2 years. RESULTS: A total of 770 deliveries were part of this QI study from October 2018 to December 2020. There was a significant improvement in DCC (median) from a baseline of 25% to 96% over a 2-year period. Sensitisation, making DCC part of pre-birth checklist and recording outcomes on a dashboard daily helped to implement and sustain the processes over 2 years. As a co-process, EBFI improved (median) from a baseline of 50% to 97% without any major intervention in the system. CONCLUSIONS: Immediate newborn care processes could be sustained by making them part of pre-birth preparation and dashboard recording by a QI initiative without any additional resources.

Coping with autism during lockdown period of the COVID-19 pandemic: A cross-sectional survey.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is thought to have greatly impacted families of individuals with autism spectrum disorder (ASD) due to lockdown, given lack of access to healthcare, therapy, and day-care centers. This survey was conducted to understand the magnitude of the impact of lockdown, and its effect on the health and behavior of individuals with ASD and their families. MATERIALS AND METHODS: We conducted an anonymous online survey, disseminated to families registered with our hospital and collaborating centers. The survey questionnaire collected information on sociodemographic details, details of the patient's and parents' behavior and health during the COVID-19 lockdown, and treatment details of the patient. RESULTS: A total of 153 families completed the survey. Of the 153, nearly half of the individuals with ASD had an inadequate understanding of lockdown, 54% had increased screen-time, while a third reported new-onset behavioral changes. About 40% received online therapies, of which 85% reported benefits. Of the 132 who answered the parent's section, 55% reported decreased interest and/or pleasure in doing daily activities and 43% felt depressed and/or hopeless. About 80% of families reported short-term positive changes such as improved speech, language skills, and participation in household chores. CONCLUSION: The COVID-19 pandemic has disrupted routines, triggered behavioral issues in individuals with ASD, and impacted the coping skills of both individuals and families, along with the mental health and well-being of the family. Valuable suggestions to improve therapy services and clinical care using technology have been uncovered and need to be explored.

High pressure, temperature and time-dependent effects on enzymatic and microbial properties of fresh sugarcane juice.

Efficacy of variable high pressure, temperature and time on the browning causing enzymes and microbial activities, which are major spoilage factors during preservation of sugarcane juice, was studied. The juice was processed at 200-600 MPa pressure for 2-8 min at 40 and 60 °C and their effect on polyphenol oxidase and peroxidase as well as microbiological quality in terms of total plate count, yeast and molds and total coliforms was studied. Application of high pressures were found to cause significant decrease in enzymatic and microbial activities. The effects were found to be significantly more pronounced at 60 °C as compared to 40 °C. Process time also caused significant (p < 0.05) negative effect on microbial and enzyme activities. The sugarcane juice treated at 600 MPa for 6 min at 60 °C was found sufficient to inactivate the microbial counts completely. Whereas, enzymes were found to be completely inactivated in the samples processed at 600 MPa for 8 min at 60 °C. A pressure of 600 MPa at 60 °C for 8 min could be applied during commercial preservation of sugarcane juice for getting complete inactivation of browning causing enzymes and spoilage causing microorganisms.

Use of high pressure technology for the development of novel jam and its quality evaluation during storage.

Jam like product was prepared using high pressure (HP) processing technology and was compared with thermally processed one for quality attributes. Strawberry pulp was mixed with pectin (1%) and sugar and packed in low density polyethylene pouches (50 g pack size) and processed at 200, 400 and 600 MPa for 30 min at 50 °C. Ascorbic acid, anthocyanins, phenolics, flavonoids and antioxidant activities were found to be significantly retained to a better extent in HP processed jams as compared to thermally processed one. The CIE L*, a* and b* values decreased significantly with increase in pressure, the decrease being of much lesser extent compared to thermally processed one. Increase in pressure was found to increase the sensory attributes for colour, appearance, flavour, texture and overall acceptability significantly; however, the scores were comparatively lesser than that of thermally processed jam. The sample processed at 600 MPa showed a shelf-life of 3 months on the basis of physico-chemical, sensory and microbial attributes when stored at ambient storage conditions (28 ± 5 °C).

Shellac and Aloe vera gel based surface coating for shelf life extension of tomatoes.

Shellac (S) and Aloe vera gel (AG) were used to develop edible surface coatings for shelf-life extension of tomato fruits. The coating was prepared by dissolving de-waxed and bleached shellac in an alkaline aqueous medium as such as well as in combination with AG. Incorporation of AG in shellac coating improved permeability characteristics of the coating film towards oxygen and carbon dioxide and water vapours. The coatings when applied to tomatoes delayed senescence which was characterized by restricted changes in respiration and ethylene synthesis rates during storage. Texture of the fruits when measured in terms of firmness showed restricted changes as compared to untreated control. Similar observations were also recorded in the case of instrumental colour (L*, a* and b* values). The developed coatings extended shelf-life of tomatoes by 10, 8 and 12 days in case of shellac (S), AG and composite coating (S + AG) coated fruits, respectively; when kept at ambient storage conditions (28 ± 2 °C).

Process optimization for osmo-dehydrated carambola (Averrhoa carambola L) slices and its storage studies.

An osmotic-dehydration process protocol for Carambola (Averrhoacarambola L.,), an exotic star shaped tropical fruit, was developed. The process was optimized using Response Surface Methodology (RSM) following Central Composite Rotatable Design (CCRD). The experimental variables selected for the optimization were soak solution concentration (°Brix), soaking temperature (°C) and soaking time (min) with 6 experiments at central point. The effect of process variables was studied on solid gain and water loss during osmotic dehydration process. The data obtained were analyzed employing multiple regression technique to generate suitable mathematical models. Quadratic models were found to fit well (R(2), 95.58 - 98.64 %) in describing the effect of variables on the responses studied. The optimized levels of the process variables were achieved at 70°Brix, 48 °C and 144 min for soak solution concentration, soaking temperature and soaking time, respectively. The predicted and experimental results at optimized levels of variables showed high correlation. The osmo-dehydrated product prepared at optimized conditions showed a shelf-life of 10, 8 and 6 months at 5 °C, ambient (30 ± 2 °C) and 37 °C, respectively.

Pressure ulcers: an unusual complication of indwelling urethral catheter.

INTRODUCTION: Pressure ulcers are common among patients with spinal cord disorders (SCD) and occur due to unrelieved pressure on soft tissues. CASE REPORTS: Two ladies with paraplegia following acute transverse myelitis developed pressure ulcers over medial aspects of thighs due to indwelling urethral catheter. Absence of sensation, weakness of both legs and lack of knowledge about catheter care contributed to ulcer formation. CONCLUSION: Indwelling urethral catheter may unusually result in pressure ulcers over the thighs in patients with SCD. Among health professionals involved in the care of these subjects awareness is essential for preventing this complication.
