Factors Associated with Malnutrition among Newly Diagnosed Esophageal Cancer Patients
Get PDFThe study aimed to investigate the factors associated with malnutrition among newly diagnosed EC patients. A cross-sectional study included newly diagnosed EC patients from October 2020 to March 2022. Data on clinical status (diagnosis, comorbidities, and cancer stage), socio-demographic characteristics, functional status [Performance status scale using Eastern Cooperative Oncology Group (ECOG)], anthropometric measures [weight, height, and percentage of weight loss (% LOW) past 1-month], biochemical profiles [lymphocyte and serum albumin], malnutrition status [Subjective Global Assessment (SGA)] and total daily energy protein intake were assessed. The study enrolled 227 participants, and 96.5% (n=219) were malnourished. The mean for age, weight, percentage of weight loss past 6-months, SGA score, total daily energy protein intake, and serum albumin were 61.1±11.4 years, 57.7±14.4 kg, -8.6±6.5%, 12.6±3.9, 17±5 kcal/kg/day, 0.7±0.1 g/kg/day, and 35±5 g/L respectively. About 80.6% were stage III and IV, 96% experienced dysphagia, and 67% experienced muscle wasting. The % LOW past 1 month, gender, ECOG status, and lymphocyte levels were found to be the significant factors related to malnutrition among newly diagnosed EC patients (p<0.05) by a multi-linear regression test. EC patients are at high risk of being malnourished as the tumor-related symptoms include dysphagia, inadequate nutritional intake, muscle wasting, and lymphocytopenia. The current study is restricted to only one-time nutritional screening and evaluation. The current proposed model of malnutrition is a simple, useful, and efficient clinical tool to identify EC-related malnutrition followed by the early multidisciplinary-team approach-based nutrition intervention to minimize nutrition depletion, improve functional status, and enhance clinical outcomes before therapy or even higher survival rate
Dietary Knowledge, Attitudes, Practices and their Association with Demographic Factors in Type 2 Diabetes Patients
Get PDFThe study aimed to assess dietary Knowledge, Attitude, And Practice (KAP) among Type 2 Diabetes Mellitus patients at Hospital Pakar USM (HPUSM), and their associations with demographic characteristics. The study used a cross-sectional design with a convenience sampling method, and the analysis included responses from 118 participants. Their dietary KAP and demographic characteristics were assessed using an adapted and translated questionnaire based on the ADA Diabetes Self-Management Assessment Research Tool (D-SMART) and the University of Michigan Diabetes Research and Training Centre’s KAP questionnaire. The questionnaire was translated and pilot-tested among 10% of the study population to ensure clarity and understanding. Minor adjustments were made based on participant feedback. The mean age of the 118 participants was 58.0±13.3 years, with 40.7% men and 59.3% women. The vast majority of participants possessed favourable attitudes (91.5%), good dietary knowledge (84.7%), and good practice (72.9%). Specifically, the mean scores for dietary knowledge, attitude, and practice were 41.8±9.39, 5.4±1.06, and 5.3±1.6, respectively. Bivariate analyses indicated significant associations between education level and knowledge (p=0.007) and attitude (p=0.009) but not practice (p=0.942). Multivariate Analysis of Variance (MANOVA) demonstrated a significant multivariate association between education level and the combined KAP scores, Pillai’s Trace=0.182, p=0.001. The remaining demographic variables were not significantly associated with the combined KAP scores in the multivariate model (p>0.05).The results of the study indicate that, despite the fact that the majority of participants had favourable dietary knowledge, attitudes, and practices, education level significantly influenced knowledge and attitude scores. This underscores the importance of providing ongoing and targeted dietary education, particularly for individuals with lower educational attainment, to facilitate more effective dietary management among those with Type 2 Diabetes Mellitus (T2DM)

No full textArtikel ini mengkaji dinamika dan dampak sosial budaya dari praktik Doi Balanca dalam pernikahan masyarakat Bugis, serta cara mempertahankan kesucian pernikahan di tengah perubahan nilai sosial. Menggunakan pendekatan studi kasus kualitatif, data dikumpulkan melalui observasi dan wawancara mendalam. Temuan menunjukkan bahwa Doi Balanca berfungsi sebagai mekanisme untuk memastikan komitmen seorang pria terhadap calon istrinya, dengan jumlah yang dipengaruhi oleh kelas sosial, adat istiadat, peran keluarga, dan komunikasi antar-keluarga. Studi ini mengungkapkan bahwa praktik Doi Balanca berperan dalam menjaga kehormatan dan stabilitas sosial. Namun, penolakan terhadap Doi Balanca dapat menyebabkan konflik, ketegangan emosional, dan isolasi sosial, serta dampak negatif seperti lamaran yang ditolak, menjadi perawan tua, pernikahan lari, dan kehamilan di luar nikah. Oleh karena itu, memahami kompleksitas sosial dan budaya Doi Balanca sangat penting untuk menemukan solusi inklusif guna mengatasi konflik yang muncul.This article aims to systematically examine the social and cultural dynamics of the Doi Balanca practice in Bugis marriage traditions, as well as its impact on the sanctity of marriage amid shifting social values. The primary objective of this study is to understand the function of Doi Balanca as a social mechanism, the factors influencing its monetary value, and the conflicts that may arise from its rejection. This research adopts a qualitative case study approach, employing observation and in-depth interviews. The findings reveal that Doi Balanca is perceived as a symbol of a man\u27s commitment to his prospective wife, with its value and meaning shaped largely by Bugis society’s social constructs. It serves to uphold family honor and ensure social stability, yet the amount is determined by various factors such as social class, customary traditions, the role of the families involved, and inter-family communication. Rejection of this practice may lead to serious consequences, including family disputes, emotional tensions, and social exclusion—often culminating in broken engagements, elopements, or premarital pregnancies. The study concludes by emphasizing the importance of understanding the social and cultural complexities surrounding Doi Balanca in order to develop inclusive solutions to emerging conflicts. It recommends strengthening inter-family communication in determining the amount of Doi Balanca and promoting more flexible approaches that mitigate potential conflicts without eroding traditional values
Response of Porang (Amorphophallus muelleri) to the Application of Arbuscular Mycorrhizal Fungi
No full textArbuscular mycorrhizal fungi (AMF) are fungi that create symbiotic relationships with plant roots, enhance nutrient absorption, and aid in root growth initiation. The purpose of this study is to evaluate how porang plants (Amorphophallus muelleri) respond to AMF delivery at various doses. The study utilized a Completely Randomized Design with five treatments: MKK0 (control), MKK1 (15 g AMF/10 kg soil), MKK2 (25 g AMF/10 kg soil), MKK3 (35 g AMF/10 kg soil), and MKK4 (45 g AMF/10 kg soil). The characteristics measured were plant height, plant dry weight, and tuber weight. The results revealed that the MKK1 treatment produced the optimum response to the plant height of 40.75 cm, dry weight of 6.3 g, and tuber weight of 26.5 g. AMF at a dose of 15 g significantly boosted the growth and expansion of porang tubers. Due to the soil\u27s low nutrient availability, excessive AMF doses did not produce desirable outcomes. Thus, administering the appropriate dose of AMF can promote proper porang development.

BAIT BOOSTER UTILIZATION ON BOTTOM GILLNET IN PALABUHANRATU BAY WATERS
Get PDFThe technological status of bottom gillnet fishing gear (rampus net) and its fishing operation methods have not changed much in its development and tend to be static. This problem also occurs among rampus net fishermen in Palabuhanratu Bay, where there is a decrease in catch productivity. The technological innovation needed for rampus net fishing gear is the use of bait boosters to attract and gather fish so that they are easy to catch. The research activities were carried out using an experimental fishing method with 20 trips as replications by comparing between treatment of rampus net with the control. The results showed that there was an increase in catches in treatment of rampus net compared to the control. The catch consisted of 61.2% demersal fish and 38.8% pelagic fish, dominated by largehead hairtail fish. The productivity of the treatment of rampus net had a value greater than the control, namely 0.85 kg/net-piece and 0.50 kg/net-piece, respectively. The production margin of the catch of the rampus net treatment compared to the control was 70.5%.

FISHERMEN’S PERCEPTION ON PORTABLE COOLING MACHINES WITH SOLAR PANELS AT BATU BERIGA, CENTRAL BANGKA REGENCY
Get PDFThis study aims to analyze the perceptions of Batu Beriga fishermen regarding the use of portable cooling machines powered by solar panels as an alternative to ice in handling fish catches. The technology is considered promising as it reduces dependence on ice blocks, lowers operational costs, and helps maintain fish freshness for longer periods. A descriptive quantitative approach was employed, using a structured questionnaire administered to 40 active fishermen with at least five years of fishing experience. Perceptions were assessed through 10 indicators covering functionality, economic benefits, ease of use, compatibility, technical complexity, and impact on catch quality. The results reveal that most fishermen expressed positive perceptions, with the highest agreement on the machine’s function as an ice substitute (95%) and its adaptability to vessel conditions (90%). However, concerns remain regarding the initial investment cost and fabrication complexity, as only 50% of respondents agreed with this aspect. Overall, the findings highlight a strong relative advantage and compatibility, while technical complexity persists as a major challenge. The study underscores the need for policy support in the form of technology subsidies, soft loans, and technical training programs to facilitate wider adoption. Such interventions are expected to accelerate the integration of renewable energy technologies into small-scale fisheries, reduce fishermen’s operational costs, and strengthen post-harvest handling systems. Furthermore, the adoption of solar-powered cooling technology aligns with the Sustainable Development Goals (SDGs), particularly Goal 7 (Affordable and Clean Energy) and Goal 14 (marine ecosystem).
