Effectiveness of Family-Based Diabetes Management Intervention on Glycated Haemoglobin Among Adults With Type 2 Diabetes: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Glycated hemoglobin (HbA1c) control is a crucial goal in the management of type 2 diabetes mellitus (T2DM), requiring lifelong commitment and family support. This study aimed to assess the effectiveness of family-based diabetes management intervention on HbA1c among adults with T2DM. From inception up to 2022, a comprehensive literature search was conducted across PubMed, ProQuest, Scopus, CORE, and the Cochrane Library. The quality of studies was evaluated using the Joanna Briggs Institute (JBI) Critical Appraisal tools. Effect sizes were calculated using standard deviations (SD), while the degree of heterogeneity was evaluated using the Higgins I2 test. Subgroup analyses were performed to explore factors contributing to sources of heterogeneity among trials. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed, and the protocol was registered with PROSPERO CRD42022384034. A total of 18 randomized controlled trials (RCTs) involving 2815 participants indicated that family-based diabetes management intervention had a statistically significant impact on improving HbA1c (Mean Difference [MD] = -.47; 95% Confidence Interval [CI]: -.64 to -.30, p < .001) with a moderate level of heterogeneity (I2 = 59%). Subgroup analysis indicated that family-based diabetes management intervention among adults with T2DM in developing regions was more effective in improving HbA1c levels compared to developed countries. Family-based diabetes management interventions improved HbA1c. Further research is required to develop diabetes management strategies with a family focus that clearly defines the family's involvement.

NUTRIENT PROFILE BLACK SOLDIER FLY LARVAE (HERMETIA ILLUCENS): EFFECT OF FEEDING SUBSTRATE AND HARVESTED TIME

The objective of this study was to asses the effect of different feeding substrates (FS), harvesting times (HT), and the interaction between FS and HT on the chemical composition of black soldier fly larvae (BSFL). The experiment used a 4 x 2 factorial arrangement with two main factors, FS (T1, T2, T3, T4), and HT (15-d and 20-d). Thus, there were eight treatment combinations, all together with five replications. The results show that there was no interaction (P&gt;0.05) between FS and HT on dry matter (DM), crude protein (CP), crude lipid (CL), phosphorus (P), gross energy (GE), and amino acid contents. The ash content of BSFL grown on T2 media and harvested on day 15 was higher (P&lt;0.05) than those grown on T2 media and harvested on day 20. The calcium (Ca) content of BSFL grown on all media and harvested on day 20 was higher (P&lt;0.05) than those harvested on day 15. In conclusion, combining fruit wastes and tofu by-products produced BSFL with high CP content but low CL, ash, Ca, and P contents. In addition, BSFL grown on all substrates media and harvested on day 15 had better CP, Ca, and P contents. The dispensable amino acid of BSFLs fed with T3 diets was the best. The lowest body weight gain was produced by feeding a substrate containing a high percentage of rice bran. The findings indicate that the best nutrient composition of BSFL as animal feed would be achieved in early harvest time (15-d) and grown in heterogeneous feeding substrates.

Numerical and experimental investigation of static shaft Wankel expander for compressed-air energy storage

Compressed air energy storage (CAES) is a promising technology for storing mechanical and electrical energy using the gas power cycle. The expansion device is a critical component of the CAES that determines the overall performance of the system. Standard Wankel expander (SWE) is one of the volumetric expanders which has several advantages including low vibration, ability to produce high power output, low manufacturing cost and less moving parts. However, SWE requires valves for timing the inlet and outlet flow and a balancing system to ensure reliable operation. Static shaft Wankel expander (SSWE) is an attractive solution to enable valves’ removal and the need for balancing system. This paper presents a detailed experimental and numerical investigation of an SSWE performance at various operating pressures and temperatures for CAES application. An advanced computational fluid dynamic simulation model taking into account the dynamic motion of the SSWE and utilising real gas air properties. A compressed air test rig was constructed and instrumented with temperature, flow rate, pressure and torque sensors. Experimental testing at temperatures 20 °C to 80 °C and pressures of 1.5 bara to 3 bara was conducted and compared to the CFD simulations results. Correlations were developed for the friction power loss. Experimental results showed that the developed SSWE can produce power output of 504 W at 80 °C and 3 bara and its isentropic efficiency reached 71 % at 60 °C and 2 bara.

Spirituality-based environmental literacy among prospective biology teacher in Indonesia: Analysis based on gender, accreditation, and semester-level aspects

Spirituality-based environmental literacy (SEL) influences ecological knowledge, environmental expectations, cognitive abilities, and environmental-related behavior. In this regard, this research aims to determine SEL among prospective biology teacher throughout Indonesia. This study included a cross-sectional survey. The target respondents are students of education study programs in the field of biology who come from various institutions in Indonesia. Gender aspects, study program accreditation status, and semester-level are positioned as respondent characteristics whose impact on environmental literacy is analyzed. The sample size is 632 students. The data collection instrument used was the ELIS. The data collection process is carried out online. Data was analyzed using SPSS. We discuss the results of different tests based on gender, different tests based on accreditation, and different tests based on semester-level. This research provides unique results. Women have higher levels of SEL than men. There are significant differences between men and women in terms of environmental literacy, although references do not always support this. Accreditation status does not support differences in SEL levels. Furthermore, the semester-level (final semester) has a higher SEL, but that is only in the knowledge aspect. On that basis, we suggest several aspects to consider in future research.

Path analysis model for preventing stunting in dryland area island East Nusa Tenggara Province, Indonesia.

The problem of stunting is still a fundamental problem in Indonesia's human development. East Nusa Tenggara Province is an archipelago dryland area where in 2007-2021 it has contributed to the highest number of stunting children prevalence in Indonesia. This study aims to determine the relationship of variables in individual, household and district level with the prevalence of stunting. This type of research is observational study with a cross sectional design. This study used individual secondary data from the Indonesian Nutritional Status Survey in 2021 consisting of 7,835 toddlers and National Social Economics Survey 2021. This research found that both specific & sensitive intervention programs had an influence in accelerating the decline in stunting prevalence (higher score on Z Score). Results also revealed the positive influence of the food access variable on nutritional intake. The results of the path analysis test showed that sensitive intervention program variables have a positive effect on food access variable and environmental variable (environmental sanitation) such as the habit of open defecation and healthcare. There was significant relationship on disease history, environment and intake to Height for Age (HAZ) score. In conclusion, direct and indirect factors have important roles to prevent stunting. Sensitive and specific intervention program, food access, macro determinants and environment are the indirect indicators which contribute significantly to the stunting. The risk of children under five years old experiencing malnourished nutritional status increases with a history of infectious disease (diarrhea, ARI, worms). The risk of children under five years experiencing malnourished nutritional status decreases with adequate nutritional intake. It is hoped that there will be a special model of stunting control interventions at the individual level and at the family, household and district level that are integrated and of high quality through multisectoral cooperation in the dryland areas of the islands of East Nusa Tenggara Province.
