Food insecurity, eating behaviour, and relative weight change among young adults in the aftermath of the COVID-19 lockdown

This study aims to investigate the association between food insecurity, eating behaviour and relative weight change among Malaysian young adults in the aftermath of the pandemic-led lockdown. Socio-demographics, body height, and body weight were self-reported by the young adults. Food security was assessed using the 8-item validated Food Insecurity Experience Scale (FIES), while the Three-Factor Eating Questionnaire-Revised 18-item (TFEQ-R18) was adopted to evaluate the eating behaviour of young adults. Of the 447, 45.9% maintained the same body weight as before the pandemic-led lockdown. While almost half of the young adults (47.2%) were food secure, about one-fourth (24.8%) suffered moderate-to-severe food insecurity. Meanwhile, the standardised raw scores for all the eating behaviour subscales were in the ascending order of cognitive restraint (49.37 ± 18.60) < uncontrolled eating (50.61 ± 20.37) < emotional eating (50.68 ± 24.50). The findings of the Sobel test indicated that the mediation effects of eating behaviour were not statistically significant (p > 0.05), suggesting that eating behaviour (cognitive restraint, uncontrolled eating and emotional eating) did not mediate the relationship between moderate-to-severe food insecurity and relative weight change. Health promotion interventions such as introducing food assistance programs, offering incentives for nutritious food purchases, and re-emphasising healthy eating are essential to rectify food insecurity and disordered eating among Malaysians.

High-dose pulse methylprednisolone vs. dexamethasone standard therapy for severe and critical COVID-19 pneumonia: Efficacy assessment in a retrospective single-centre experience from Malaysia

INTRODUCTION

The use of dexamethasone (DXM) has been associated with decreased mortality in the patients with hypoxemia during the coronavirus disease-2019 (COVID-19) pandemic, while the outcomes with methylprednisolone (MTP) have been mixed. This real-life study aimed to evaluate the outcomes of patients with severe respiratory failure due to COVID-19 who were treated with high doses of MTP.

MATERIALS AND METHODS

This retrospective cohort study enrolled hospitalised patients between May 2021 and August 2021, aged 18 years and above, with severe respiratory failure defined by a ratio of oxygen saturation to fraction of inspired oxygen (SF ratio) of less than 235. The treatment protocol involved administering high-dose MTP for 3 days, followed by DXM, and the outcomes were compared with those of patients who received DXM alone (total treatment duration of 10 days for both groups).

RESULTS

A total of 99 patients were enrolled, with 79 (79.8%) receiving pulse MTP therapy and 20 (20.2%) being treated with DXM only. The SF ratio significantly improved from a mean of 144.49 (±45.16) at baseline to 208 (±85.19) at 72 hours (p < 0.05), with a mean difference of 63.51 (p < 0.001) in patients who received ≤750 mg of MTP. Additionally, in patients who received >750 mg of MTP, the SF ratio improved from a baseline mean of 130.39 (±34.53) to 208.44 (±86.61) at 72 hours (p < 0.05), with a mean difference of 78.05 (p = 0.001). In contrast, patients who received DXM only demonstrated an SF ratio of 132.85 (±44.1) at baseline, which changed minimally to 133.35 (±44.4) at 72 hours (p = 0.33), with a mean difference of 0.50 (p = 0.972). The incidence of nosocomial infection was higher in the MTP group compared with the DXM group (40.5% vs. 35%, p = 0.653), with a relative risk of 1.16 (95% CI: 0.60-2.23).

CONCLUSION

MTP did not demonstrate a significant reduction in intubation or intensive care unit admissions. Although a high dose of MTP improved gas exchange in patients with severe and critical COVID-19, it did not provide an overall mortality benefit compared to standard treatment.

Globus pharyngeus due to a lymphangiomatous polyp arising from the tonsil

INTRODUCTION

Lymphangiomatous polyp of the tonsil is generally accepted as a hamartomatous lesion. Its differential diagnosis includes fibroepithelial polyp, squamous papilloma, angiofibroma, haemangioma, arteriovenous malformation, hamartoma and lymphangioma.

CASE REPORT

A 33-year-old man presented with 2 months history of feeling of foreign body sensation in the throat. Examination revealed a nodular red coloured polyp on the left tonsil. Histologically, the polyp was covered by squamous epithelium and is composed of numerous vascular channels containing lymphocytes and eosinophilic material, in a fibrous stroma. Immunohistochemically, the endothelial cells were positive toward CD31 and D2-40.

DISCUSSION

The characteristic histological features of a lymphangiomatous polyp are benign vascular proliferation with variable fibrous, adipose and lymphoid stromal components. Nested intraepithelial epidermotropism of lymphocytes can be observed. The vascular channels are typically thin-walled and contain eosinophilic proteinaceous material and lymphocytes. There is no reported incidence of recurrent or malignant transformation.

Effects of Sonication and Thermal Pasteurization on the Nutritional, Antioxidant, and Microbial Properties of Noni Juice

Sonication is recognized as a potential food processing method to improve the functional properties of fruit juice. This study evaluated the effects of different sonication durations (20, 40, and 60 min) and thermal pasteurization on the nutritional, antioxidant, and microbial properties of noni juice. Fresh noni juice served as the control. The main organic acids detected were malic (57.54−89.31 mg/100 mL) and ascorbic (17.15−31.55 mg/100 mL) acids. Compared with the fresh sample, the concentrations of these compounds were significantly improved (p < 0.05) in the 60 min sonicated sample but reduced (p < 0.05) in the pasteurized sample. Moreover, sonication for 60 min resulted in increments of scopoletin, rutin, and vanillic acid compared to the fresh sample. The antioxidant activity of the juice sample was improved in the sample sonicated for 60 min. Irrespective of juice processing method, the level of microbial counts in noni juice was within the satisfactory level over the 8 weeks of refrigerated (4 °C) storage. This study highlights the feasibility of using ultrasound processing to enhance the quality of noni juice on the industrial scale.

Knowledge, attitudes, and practices towards COVID-19 among undergraduates during emergency remote learning

Background

The coronavirus disease 2019 (COVID-19) pandemic paralyzes the education sector. To minimize the interruption of teaching and learning, most universities in Malaysia shifted to virtual mode during this unprecedented period of the pandemic. With an ever-increasing number of Malaysians fully vaccinated against COVID-19, the education system is expected to switch back to face-to-face mode this year. It is crucial to assess the knowledge, attitudes, and practices (KAP) of COVID-19 among emergency remote learning undergraduates before reverting to physical teaching and learning. Hence, a study was conducted with this aim in mind.

Methods

A total of 299 Malaysian undergraduates were recruited through a snowball sampling approach. The online questionnaire encompassed three main segments: informed consent, sociodemographic information, and KAP questions on COVID-19.

Results

The mean scores for knowledge, attitude, and practice were 4.05/6, 11.14/12, and 5.07/7, respectively. The results of the present study showed that year 1 respondents had significantly higher levels (p < 0.05) of KAP scores than year 4 respondents. In addition, the attitude score of science majors respondents was significantly greater (p < 0.05) than those of nonscience majors. The KAP scores showed no significant difference among groups with different sexes, ethnicities, and COVID-19 histories. Partial correlation analysis revealed that the overall knowledge score was positively correlated with attitude (r = 0.193, p = 0.001) and practice (r = 0.343, p < 0.001) scores whereas the total attitude score was positively correlated with the total practice score (r = 0.149, p = 0.010).

Conclusion

Our current results suggest that COVID-19 workshops, seminars, or training programs for year 4 students could be conducted to enhance their KAP levels.

Prevalence and factors associated with sexual dysfunction among middle-aged women in a multi-ethnic country: A cross sectional study in Malaysia

INTRODUCTION

This study aimed to determine the prevalence and factors associated with female sexual dysfunction in an outpatient clinic in Malaysia.

METHODS

The study was conducted among female patients aged 50 years and older who attended the outpatient clinic of a public hospital in Malaysia. A self-administered questionnaire was used that was based on the Malay version of the Female Sexual Function Index questionnaire. The predictors of female sexual dysfunction were identified using multivariate logistic regression analysis.

RESULTS

A total of 263 females were recruited in this study, with a mean age of 60.6 ± 6.7 years. The distribution of the respondents' ethnicities was mostly Malay (42.2%), followed by Chinese (41.8%) and Indian (16.0%). The prevalence of female sexual dysfunction among participants was 68.8%. The prevalence of the subscales of female sexual dysfunction was as follows: desire (85.2%), satisfaction (74.9%), arousal (71.1%), lubrication (66.9%), pain (61.2%), and orgasm (60.8%). According to multivariate logistic regression, patients of Indian ethnicity had an increased risk of female sexual dysfunction (0R=16.60, 95% CI=2.54-108.63), and a higher frequency of sexual intercourse was correlated with a lower risk of female sexual dysfunction (0R=0.13, 95% CI=0.08-0.24).

CONCLUSION

Seven-tenths of the middle-aged female patients attending the outpatient clinic suffered from female sexual dysfunction. Indian ethnicity and having a lower frequency of sexual intercourse were predictors of female sexual dysfunction. Future intervention studies are needed to address this problem.

Food security during the COVID-19 home confinement: A cross-sectional study focusing on adults in Malaysia

The surge in coronavirus disease 2019 (COVID-19) transmission cases has led to the decision to execute the Movement Control Order (MCO) by the Federal Government of MalaysiaEconomic activities, psychological wellbeing, and food security may be negatively affected by the implementation of MCO. Therefore, this study aims to assess the prevalence of food insecurity and its associated factors during the enforcement of MCO 1.0. A total of 162 respondents were enrolled in this study using convenience and snowball sampling approaches. Socio-demographic information was self-reported by the respondents. Food security and the presence of depressive symptoms during the MCO 1.0 were assessed with Food Insecurity Experience Scale (FIES) and Patient Health Questionnaire-2 (PHQ-2), respectively. Current findings demonstrated that the prevalence of food insecurity was 43.2%. Ethnicity, marital status, employment status, monthly earned income and being the head of a household were significantly associated (p< 0.05) with food insecurity during the MCO 1.0. A higher odds ratio for food insecurity were observed among Malaysian Indian (OR = 2.541, CI: 1.041-6.205), those with active employment during the MCO 1.0 (OR = 4.175, CI: 1.189-14.660) and those with a monthly income of less than RM4000 during the MCO 1.0 (OR = 5.396, CI: 1.362-21.838). In conclusion, policymakers are urged to pay more attention to these vulnerable populations when formulating economic stimulus plans and coping strategies for food insecurity in the post-COVID-19 era.

Changes in Dietary Intake Patterns and Weight Status during the COVID-19 Lockdown: A Cross-Sectional Study Focusing on Young Adults in Malaysia

Introduction: The coronavirus disease 2019 (COVID-19) isolation has altered individuals’ food purchasing behaviour and dietary intake patterns. Therefore, this study aims to investigate the changes in dietary intake patterns and their impacts on the weight status of young adults in Malaysia during the COVID-19 lockdown. Methods: This cross-sectional study involved 1045 young adults in Malaysia. The changes in dietary intake patterns were assessed using the Dietary Diversity Questionnaire with slight modifications, while anthropometric measurements including body height, body weight before the pandemic and current body weight were self-reported. Results: Overall, nearly half of the respondents (48.8%) gained weight during the confinement, with an average increment of 4.06 ± 3.23 kg. Of 1045, 45.3% reported consuming more fruits and 60.2% had higher plain water intake during the pandemic. It is observed that 41.0% to 66.8% of the young adults changed their dietary intake patterns during the pandemic. Increased consumption in cereals and grains (β = 0.084, p = 0.015, 95% CI = 0.017–0.160), as well as oils and fats (β = 0.123, p = 0.001, 95% CI = 0.059–0.241), was positively associated with weight gain during the pandemic. On the contrary, an increased plain water intake was negatively associated with weight gain during the lockdown (β = −0.100, p = 0.003, 95% CI = −0.171–−0.034). Findings in the current study also suggested that cutting back cereals and grains (β = 0.156, p < 0.001, 95% CI = 0.122–0.288), as well as oils and fats (β = 0.091, p = 0.012, 95% CI = 0.022–0.183), contributed significantly to weight loss during the pandemic confinement. Conclusion: In conclusion, the enforcement of the Movement Control Order (MCO) drove up the prevalence of overweight/obesity among young adults in Malaysia. Increased consumption of cereals and grains and oils and fats contributed to weight gain in the pandemic lockdown. Nonetheless, a noticeable proportion of young adults in Malaysia shifted to a healthier food choice by increasing the consumption of fruits and vegetables.

Eating Behaviors among Online Learning Undergraduates during the COVID-19 Pandemic

The outbreak of Coronavirus Disease-2019 (COVID-19) has upended education systems. The pandemic switched traditional face-to-face classes to online classes. Poor eating behaviors in undergraduate students' lives may affect the well-being of their later stages of life. This study aimed to investigate the eating behaviors among online learning undergraduates during the COVID-19 pandemic. A total of 122 students were recruited. The results revealed more than half of the respondents (52.46%) skipped meals. Breakfast (46.72%) was the most skipped meal. The majority of the respondents (94.26%) snacked between meals. Biscuits (88.52%), bread (84.43%), and fruits (80.33%) were the most common snacked foods. Meal skipping was found to be associated with gender (χ² = 6.83, p < 0.05). In the future, more health interventions program aimed to promote healthy eating behaviors among undergraduates are highly warranted.

High-sensitivity single-shot perfusion-weighted fMRI

A method is presented for measurement of perfusion changes during brain activation using a single-shot pulsed spin labeling technique. By employing a double-inversion labeling strategy, stationary tissue (background) signal was suppressed while minimally affecting perfusion sensitivity. This allowed omission of the otherwise required reference scan, resulting in twofold-improved temporal resolution. The method was applied to visual and motor cortex activation studies in humans, and compared to standard FAIR-type perfusion labeling techniques. Experiments performed at 1.5T and 3.0T indicate a close to 90% suppression of background signal, at a cost of an 11% and 9%, respectively, reduction in perfusion signal. Combined with the twofold increase in signal averaging, and a reduction in background signal fluctuations, this resulted in a 64% (1.5T, N = 3) and a 128% (3T, N = 4) overall improvement in sensitivity for the detection of activation-related perfusion changes.

A protocol for assessing subtraction errors of arterial spin-tagging perfusion techniques in human brain

A protocol for assessing signal contributions from static tissue (subtraction errors) in perfusion images acquired with arterial spin-labeling (ASL) techniques in human brain is proposed. The method exploits the reduction of blood T(1) caused by the clinically available paramagnetic contrast agent, gadopentetate dimeglumine (Gd-DTPA). The protocol is demonstrated clinically with multislice FAIR images acquired before, during, and after Gd-DTPA administration using a range of selective inversion widths. Perfusion images acquired postcontrast for selective inversion widths large enough (threshold) to avoid interaction with the imaging slice had signal intensities reduced to noise level, as opposed to subtraction errors manifested on images acquired using inversion widths below the threshold. The need for these experiments to be performed in vivo is further illustrated by comparison with phantom results. The protocol allows a one-time calibration of relevant ASL parameters (e.g., selective inversion widths) in vivo, which may otherwise cause subtraction errors. Magn Reson Med 43:896-900, 2000.
