Published: February 2024

A method was developed and validated for vanillin, ethyl vanillin, and methyl vanillin determination in Thai rice cultivars by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) under the selected reaction monitoring mode. In rice samples, the limit of detection was 13.3, 11.2 and 5.0 mg/kg for vanillin, ethyl vanillin, and methyl vanillin. A high correlation coefficient was obtained (R2 = 0.9999, 0.9999 and 0.9998) within the linear range (0 - 300 mg/L) in the MS method. The recoveries ranging from 90.63 % ± 6.25 to 108.7 % ± 2.35 were obtained in different spiking concentrations. The average RSD% of intra-day for vanillin, ethyl vanillin, and methyl vanillin was 6.90, 5.13 and 2.16 %, and the inter-day were 6.72, 5.30 and 5.64 %, respectively. The developed method was applied to 24 commercial rice samples. Vanillin, were found in 24 samples ranging from 95.2 to 773.2 mg/kg. However, ethyl vanillin and methyl vanillin were not detected under LOD. The developed UPLC-MS/MS method for vanillin, ethyl vanillin and methyl vanillin determination include the merits of simple preparation steps and high sensitivity.

Authors: Almuqrin Abdulaziz , Alshuweishi Yazeed Abdullah , Alfaifi Mohammed , Daghistani Hussam , Al-Sheikh Yazeed A. , Alfhili Mohammad A. 
Published: February 2024

BACKGROUND:
Hyperuricemia is linked to an increased risk of various chronic diseases, but data on the prevalence and association of hyperuricemia with liver function in Saudi Arabia are scarce.

OBJECTIVES:
Evaluate the prevalence, association, and risk measures of hyperuricemia and liver function in the Saudi population.

DESIGN:
Retrospective, cross-sectional analysis

SETTING:
Database on large portion of Saudi population

PATIENTS AND METHODS:
Laboratory data, age, and gender of the studied subjects were collected from Al Borg Diagnostics. Subjects were stratified, based on their uric acid (UA) levels, into three groups: hypouricemic, normouricemic, and hyperuricemic. The association of UA with liver enzymes was examined in all three groups.

MAIN OUTCOME MEASURES:
Association of serum UA levels with alanine transaminase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), and total bilirubin (TB).

SAMPLE SIZE:
13 314 subjects.

RESULTS:
Our study showed that the prevalence of hyperuricemia in the Saudi population is 17.3% (20.3% in males and 15.1% in females). We also found a positive correlation between ALT, AST, and TB with UA levels. The risk of being hyperuricemic was significantly increased in individuals with elevated ALT, AST, and TB. Individuals with elevated ALT, AST, and total TB had a higher chance of having hyperuricemia than those with normal activity. Notably, ALT, AST, and TB had good discriminating capacity for hyperuricemia.

CONCLUSIONS:
Hyperuricemia is highly prevalent in the Saudi population and is associated with compromised liver function. However, further studies are needed to elucidate the mechanisms underlying these findings in large prospective cohort studies in different populations.

LIMITATIONS:
Lack of data on other potential confounding variables.

Published: February 2024

Abstract. It has been demonstrated that HALO Photonics Doppler lidars (denoted HALO Doppler lidar hereafter) have the capability for retrieving the aerosol particle depolarization ratio at a wavelength of 1565 nm. For these lidars operating at such a long wavelength, the retrieval quality depends to a large degree on an accurate representation of the instrumental noise floor and the performance of the internal polarizer, whose stability has not yet been assessed for long-term operation. Here, we use 4 years of measurements at four sites in Finland to investigate the long-term performance of HALO Doppler lidars, focusing on aerosol particle depolarization ratio retrieval. The instrumental noise level, represented by noise-only signals in aerosol- and hydrometeor-free regions, shows stable performance for most instruments but clear differences between individual instruments. For all instruments, the polarizer bleed-through evaluated at liquid cloud base remains reasonably constant at approximately 1 % with a standard deviation of less than 1 %. We find these results to be sufficient for long-term aerosol particle depolarization ratio measurements and proceed to analyse the seasonal and diurnal cycles of the aerosol particle depolarization ratio in different environments in Finland, including in the Baltic Sea archipelago, a boreal forest and rural sub-arctic. To do so, we further develop the background correction method and construct an algorithm to distinguish aerosol particles from hydrometeors. The 4-year averaged aerosol particle depolarization ratio ranges from 0.07 in sub-arctic Sodankylä to 0.13 in the boreal forest in Hyytiälä. At all sites, the aerosol particle depolarization ratio is found to peak during spring and early summer, even exceeding 0.20 at the monthly-mean level, which we attribute to a substantial contribution from pollen. Overall, our observations support the long-term usage of HALO Doppler lidar depolarization ratio measurements, including detection of aerosols that may pose a safety risk for aviation.

Published: February 2024

Diabetes Mellitus is a non-communicable disease that continues to experience an increase in the number of cases with high mortality and morbidity rates, expected to triple by the year 2030. In the long term, it can lead to microvascular, macrovascular, and neuropathic complications such as peripheral vascular disease, indicating abnormalities in the lower limbs, manifested as diabetic ulcers. The research aims to determine the Influence of Diabetic Foot Exercises on the Risk of Diabetic Ulcers in Patients with Diabetes Mellitus at Sukosari Community Health Center in Babadan Subdistrict, Ponorogo Regency. The research design is a pre-experimental study with a One Group Pretest-Posttest approach. The study was conducted from June to August 2023. The population consisted of all Diabetes Mellitus patients at Sukosari Community Health Center in Babadan. Sample of 30 respondents was selected using purposive sampling. The independent variable was the risk of diabetic ulcers, and the dependent variable was diabetic foot exercises. The observation instrument used was Inlow's 60-second diabetic foot screening tool. Statistical analysis was performed using the Wilcoxon signed-rank test through SPSS with α = 0.05. The research results showed that the risk of diabetic ulcers before diabetic foot exercises, more than half of the respondents (63.3%), had a moderate category, and 43.3% had a mild category. There is an influence of Diabetic Foot Exercises on the Risk of Diabetic Ulcers in Patients with Diabetes Mellitus at Sukosari Community Health Center in Babadan Subdistrict, Ponorogo Regency, with a p-value of 0.000 ≤ α 0.05. Diabetic foot exercises can be performed independently, without the need for equipment, and at no cost. It is hoped that patients with Diabetes Mellitus can perform them regularly, systematically, and continuously, with the expectation of reducing the risk of diabetic ulcers.

Published: February 2024

Development countries are often linked to heightened rural-to-urban migration rates, along with widespread unemployment and high fertility rates in rural areas, including Indonesia. This research aims to investigate the impact of unemployment rates and life expectancy on the population levels in Indonesian urban areas. The data used is Indonesian’s urban population, unemployment rate, and life expectancy from 2003-2022 that published by The World Bank and the United Nations-World Population Prospect and it is analyzed using quantitative methods. Based on time-series regression data, the research indicates a significant influence of both unemployment rates and life expectancy on population levels in urban areas of Indonesia. This highlights developmental disparities between regions, particularly in rural and urban area, although there are signs of increased employment opportunities in rural regions. Therefore, monitoring and evaluation, both by the government and the community, are necessary for ensuring that government budget allocations are precise, effective, and efficient.
Negara berkembang identik dengan tingkat migrasi dari desa ke kota yang tinggi, dan persebaran angka pengangguran dan angka fertilitas yang tinggi di daerah pedesaan, salah satunya adalah Indonesia. Penelitian ini berusaha menganalisis pengaruh tingkat pengangguran dan angka harapan hidup terhadap tingkat populasi penduduk di daerah perkotaan di Indonesia. Data yang digunakan adalah tingkat populasi di daerah perkotaan, tingkat pengangguran, dan angka harapan hidup Indonesia pada tahun 2003-2022 yang dipublikasikan oleh The World Bank dan United Nations-World Population Prospect yang dianalisis menggunakan metode kuantitatif. Berdasarkan hasil regresi data time-series, hasil penelitian menujukkan bahwa tingkat pengangguran dan angka harapan hidup berpengaruh signifikan terhadap tingkat urbanisasi di Indonesia. Hal ini menunjukkan adanya kesenjangan pembangunan antar daerah khususnya di daerah pedesaan dan perkotaan, namun terdapat indikasi peningkatan lapangan kerja di daerah pedesaan. Dengan demikian, perlu dilakukan monitoring dan evaluasi baik dari pemerintah maupun masyarakat pada penyaluran alokasi anggaran belanja pemerintah agar lebih tepat sasaran, efektif, dan efisien.

Whooping cough (pertussis) caused by Bordetella pertussis is a highly contagious respiratory tract infection. continues to be a global public health problem. The World Health Organization reported 151,074 cases of pertussis worldwide and estimated 89 000 deaths in 2018. In recent years, pertussis epidemics have been observed in countries that have maintained high vaccination coverage. According to the official report of the Ministry of Health and Sports, the total accumulated cases of Coqueluche in Bolivia reach 756, of which 469 are up to 5 years old and 287 older than that age range and 8 deaths had to be regretted until August 10, 2023. Coqueluche is a notifiable disease. It is important to reflect that infectious diseases have no borders; a relevant question would be whether Bolivia is prepared or is failing to control this outbreak of reemerging disease, after COVID-19. We should not lower our guard or dismiss early action; new preventive strategies are needed.

Introduction: health-related quality of life is a broad, multidimensional, and subjective concept that represents the subject's perception of both positive and negative aspects of their physical, psychological, emotional, and social health. Objective: to analyze health-related quality of life and its relationship with self-care habits in nursing students of a private university in Argentina during the second quarter of 2023. Methods: descriptive, cross-sectional, quantitative study. We surveyed 109 nursing students using the SF-36 health questionnaire. Results: a low prevalence of habits such as smoking (3,67 %), sedentary lifestyle (39,45 %) and low attendance to regular medical consultations (41,28 %) was found. The best rated quality of life scale was Physical Function and the worst rated was Vitality. The summary physical component presented a higher mean than the mental component. Quality of life was associated with gender, marital status, having children, year of study, body mass index and hours of sleep per day. Conclusions: health-related quality of life was assessed as good, except for the vitality dimension. The students' lifestyle was mostly positive and related to physical and mental health. It is necessary to implement actions that promote self-care and the maintenance of quality of life in students.
Nutrition Periodization in Recreational Endurance Athletes During Training Camp – Case study
Authors: Kumstát Michal , Hlinský Tomáš 
Published: February 2024

Both training and dietary practices used by athletes greatly vary. Current sports nutrition guidelines promote dietary manipulation of energy-yielding nutrients specific to the period of training. The study explores the ad libitum nutrition practices of four healthy adult recreational athletes during a 2-week cycling training camp (~100 km·d-1, ~240 min·d-1) with particular attention to the current sports nutrition recommendations. Based on evidence-based guidelines, peri-exercise carbohydrate (CHO) and protein (PRO) intake periodization cut-off levels were set for athletes. Training days were categorized as hard (HARD, two training units/day), middle (MID, one training unit/day), and easy (LOW, no training). Fourteen-day diet records were used and analyzed by nutritional software for energy intake (EI), carbohydrate (CHO), and protein (PRO) intake.
Relative daily EI of 78.6±4.5, 73.3±6.4, 75.4±8.2 kcal·kg·d-1, and CHO 8.9±0.8, 7.8±1.0, 8.2±1.5 g·kg1 intakes were not different in HARD, MID and LOW days, respectively. The mean daily EI was 1.3× higher than the predicted total daily energy expenditure, irrespective of the training day category, resulting in ~500 kcal·d-1 energy surplus. In the 2h post-exercise period, PRO intake exceeded the current recommendations 4.6-fold, and CHO intake was significantly lower after a second training session on HARD days (0.7 g·kg·h-1) than a recommendation (1.2 g·kg·h-1). Mean in-exercise CHO intake (~11.5 g·h-1) was significantly under the moderate 30 g·h-1 recommendation.
In conclusion, the dietary behaviours of recreational athletes are not consistent with current sports nutrition periodization guidelines. Energy intake throughout the training camp led to positive energy balance being highest on non-training days. Daily or during and post-exercise CHO and PRO intakes were not adjusted to the training sessions' volume, intensity, or duration.
