Published: July 2023

Thirty-seven percent of children in Aceh suffer from stunting. This number is concerning. Several programs offering supplementary nutrition for children in hot areas have been conducted. However, the percentage is decreasing too slowly. It is unclear why those programs were ineffective. The study aims to explore the cause of stunting in children aged 25-59 months in the Kota Sigli Sub-district, Pidie Regency, Aceh, Indonesia. Qualitative research was conducted on January 2022 using ethnographic tools. Data were collected through participant observation, semi-structured interviews with eight (8) mothers of stunted children, and informal interviews with midwives. Result, the findings show that there are various factors that may influence the incidence of stunting in children: failure to provide exclusive breastfeeding, inappropriate complementary feeding, and problems with hygiene and sanitation that affect children’s health. In conclusion, this calls for an integrated approach to engaging the Indonesian government, parents, and communities in overcoming the root of the stunting problem: poverty.Keywords:
Use of reminder box for the amount of iron tablet consumption in pregnant women
Authors: Nurbaiti Nurbaiti
Published: July 2023

One of the health issues affecting pregnant women in Indonesia is iron deficiency anemia. Iron tablet supplementation is used to manage anemia, but this program has not been successful because of low compliance from forgetfulness. The use of a reminder can increase the amount of iron pill consumption. This study aimed to determine how much iron pill ingestion was impacted by the reminder box. This kind of research uses a post-test-only control group, which has a quasi-experimental design. Sixty respondents were divided into 30 intervention groups and 30 control groups. The intervention group received iron tablets in a box marked with the day, date, and time as a reminder to take their prescription, while the control group received theirs in plastic. Both groups were observed for 30 days, recording their observations on a monitoring form. An impartial t-test was utilized in the data analysis. The average amount of iron tablets ingested did not differ between the intervention and control groups (p= 0,417), although the intervention group consumed more than the average amount. Reminder boxes enhance consumption, but additional proof is required. It is unclear whether placing reminders where they are simple to notice and access will impact compliance.

During the research, the most promising halide salts for use as fluxes were analyzed and selected: Na3AlF6, Na2TiF6, K2TiF6, K1-3AlF4-6 (Nocolok ™ made in Germany). During the experimental synthesis, the most active signs of an exothermic reaction between titanium and carbon powders in the flux were recorded having a flux additive Na2TiF6. Then microstructural, micro X-ray spectral analysis and quantitative X-ray phase analyses were carried out, according to their results it was found out that the most homogeneous distribution in terms of material volume, the maximum content of a high dispersion of carbide phase close to the stoichiometric composition is also observed in samples obtained with the use of Na2TiF6 salt. The synthesized samples of the composite material were assessed according to physical and mechanical characteristics: hardness, porosity and electrical conductivity. It was found out that composite samples with an optimal structure are also characterized by a decrease in porosity by 1.33%, an increase in hardness by 94 MPa and a reduction of electrical conductivity by 0.3 MSm/m compared with samples obtained using other fluxes. According to the results of the studies carried out, Na2TiF6 flux is recommended for use to implement SHS composite AMg2-TiC material.

Background: The accuracy of third-trimester ultrasound in detecting large for gestational age and macrosomic fetuses in diabetic and non-diabetic pregnant women is unclear in the literature. The aim of the study is to examine the precision of the 4-parameter Hadlock formula for the prediction of large fetuses in these two populations. Methods: A systematic review and meta-analysis were performed, and only studies evaluating the accuracy of third-trimester ultrasound using the 4-parameter Hadlock formula were included. Data were extracted, and the meta-analysis was performed using STATA software and Meta-disk 2.0 aiming to obtain the pooled sensitivity and specificity. Quality assessment of the risk of bias was performed using the QUADS-2 tool. Results: Nine articles were included in the final analysis together with 24,693,702 pregnancies screened and 2336 real large fetuses. The included articles were judged to be at high risk of bias in more than half of the cases and at doubtful risk in the remaining cases. Comparison between diabetic and non-diabetic populations was impossible because the studies considered mixed pregnancies (diabetic and non-diabetic) or only healthy, so the comparison was made between the latter two groups. The pooled sensitivity was 0.54 (95% confidence interval (CI): 0.40–0.68), and the pooled specificity was 0.94 (95% CI: 0.90–0.97). The heterogeneity estimated by the Bivariate I2 was 0.92, and the area under the summary Receiver Operating Characteristics curve was 0.19. The subgroup analysis revealed a higher level of heterogeneity for the mixed group (I2 = 0.92) and a lower one for the healthy group (I2 = 0.67). The relative sensitivity between the mixed population and the healthy one was 0.85 (95% CI: 0.49–1.45; p = 0.57), and the relative specificity between the mixed population and the healthy one was 0.98 (95% CI: 0.91–1.04; p = 0.54), the difference between healthy and mixed groups was not significant (p = 0.11). Conclusions: Despite the high heterogeneity of the data, the overall accuracy of ultrasound is similar in mixed and healthy populations and is overall moderate in predicting large fetuses.

Published: July 2023

Background: Muscle atrophy resulting wholly or partially from disuse represents a serious medical complication that decreases quality of life and increases morbidity and mortality. The accumulation of misfolded/unfolded proteins disrupts endoplasmic reticulum (ER) homeostasis and thus causes ER stress. Growing evidence indicates that ER stress plays an essential role in skeletal muscle remodeling under various physiological or pathophysiological conditions. However, whether ER stress is involved in disuse-induced muscle atrophy remains unclear. Methods: To induce muscle atrophy, 8-week-old C57BL/6JNifdc male mice were subjected to 3, 7, or 14 days of hindlimb unloading (HU), and rhesus macaques (Macaca mulatta) were subjected to 10∘ head-down tilted bed rest (HDBR) for 6 weeks. Tauroursodeoxycholic acid (TUDCA) (500 mg/kg/d) was orally administered to mice during HU to inhibit ER stress. Quantitative PCR, Western blotting, and immunohistochemistry were conducted to evaluate gene, protein, and structural changes, respectively. Results: ER stress marker genes were rapidly induced by HU in a similar trend to that observed with atrophy-related genes such as Atrogin-1, muscle RING finger 1 (MuRF1), and muscle ubiquitin ligase of SCF complex in atrophy-1 (MUSA1). Inhibition of ER stress with TUDCA, a pan-ER stress inhibitor, attenuated HU-induced muscle atrophy and the upregulation of ubiquitin ligases via the AKT/forkhead box O3a pathway. In addition, the oxidative-to-glycolytic myofiber type transition caused by HU was also inhibited by TUDCA treatment. ER stress activation was also confirmed in HDBR-induced rhesus soleus muscle atrophy. Conclusions: The strong positive correlation between ER stress activation and both HU- and HDBR-induced muscle atrophy indicates that ER stress activation is ubiquitously involved in disuse-induced muscle atrophy, regardless of species. Thus, inhibiting ER stress may be an effective therapeutic strategy to prevent muscle atrophy during disuse.

Objective: Few studies have reported the direct effect of C–X–C motif chemokine ligand 10 (CXCL10) and Neuregulin 1 (Nrg1) on neurons after spinal cord injury (SCI). This study reports the role of CXCL10 in the regulation of neuronal damage after SCI and the potential therapeutic effect of Nrg1. Methods: The expression level of CXCL10 and Nrg1 in SCI mice was analyzed in the Gene Expression Omnibus DataSets, followed by immunohistochemical confirmation using a mouse SCI model. HT22 cells and NSC34 cells were treated with CXCL10 and Nrg1, individually or in combination, and then assayed for cell viability. The percentage of wound closure was determined through the cell scratch injury model using HT22 and NSC34 cells. Potential molecular mechanisms were also tested in response to either the individual administration of CXCL10 and Nrg1 or a mixture of both molecules. Results: CXCL10 expression was significantly increased in both young and old mice subjected to SCI, while Nrg1 expression was significantly decreased. CXCL10 induced a decrease in cell viability, which was partially reversed by Nrg1. CXCL10 failed to inhibit scratch healing in HT22 and NSC34 cells, while Nrg1 promoted scratch healing. At the molecular level, CXCL10-activated cleaved caspase 9 and cleaved caspase 3 were both inhibited by Nrg1 through pERK1/2 signaling in HT22 and NSC34 cells. Conclusions: CXCL10 is upregulated in SCI. Despite the negative effect on cell viability, CXCL10 failed to inhibit the scratch healing of HT22 and NSC34 cells. Nrg1 may protect neurons by partially antagonizing the effect of CXCL10.

Background: Gastric inflation (GI) can induce gastric regurgitation and subsequent aspiration pneumonia, which can prolong intensive care unit stay. However, it has not been verified in patients with out-of-hospital cardiac arrest (OHCA). This study aimed to investigate the incidence of GI during prehospital resuscitation and its effect on aspiration pneumonia and resuscitation outcomes in patients with out-of-hospital cardiac arrest. Methods: This was a multicenter, retrospective, observational study. Patients with non-traumatic OHCA aged >19 years who had been admitted to the emergency department were enrolled. Patients who received mouth-to-mouth ventilation during bystander cardiopulmonary resuscitation (CPR) were excluded from the evaluation owing to the possibility of GI following bystander CPR. Patients who experienced cardiac arrest during transportation to the hospital who were treated by the emergency medical service (EMS) personnel, and those with a nasogastric tube at the time of chest or abdominal radiography were also excluded. Radiologists independently reviewed plain chest or abdominal radiographs immediately after resuscitation to identify GI. Chest computed tomography performed within 24 h after return of spontaneous circulation was also reviewed to identify aspiration pneumonia. Results: Of 499 patients included in our analysis, GI occurred in approximately 57% during the prehospital resuscitation process, and its frequency was higher in a bag-valve mask ventilation group (n = 70, 69.3%) than in the chest compression-only cardiopulmonary resuscitation (n = 31, 55.4%), supraglottic airway (n = 180, 53.9%), and endotracheal intubation groups (n = 3, 37.5%) (p = 0.031). GI was inversely associated with initial shockable rhythm (adjusted odds ratio [OR] 0.53; 95% confidence interval [CI]: 0.30–0.94). Aspiration pneumonia was not associated with GI. Survival to hospital discharge and favorable neurologic outcomes were not associated with GI during prehospital resuscitation. Conclusions: GI in patients with OHCA was not associated with the use of different airway management techniques.
Professional identity and personal value in occupational health psychology: Overlap or eclipse?
Authors: Rizzo Amelia
Published: July 2023

Developing a professional identity encompasses acquiring specialized knowledge, understanding social work values, and integrating knowledge and values into practice, all of which are crucial components of professional competence. Professional identity combines the definition of a profession, the nature of identity, and the processes involved in acquiring that identity, both individually and within a professional group. In social work, two main theoretical frameworks are relevant: the trait approach, which focuses on individual and psychological aspects such as needs and risk-based perceptions, and the power and construction approach, which operates at the macro and social levels.

Safely managed sanitation (SMS) has been difficult to achieve in resource-limited rural areas. To support achieving sustained SMS in rural Cambodia, iDE introduced the alternating dual-pit latrine (ADP), which treats fecal sludge (FS) on-site to reduce microbial hazards using storage and lime while maintaining latrine functionality. However, FS can only be safely managed with ADPs if households perform a set of recommended practices in a certain order, particularly regarding how and when they switch between pits. To understand how real-world household sanitation practices and knowledge affect on-site FS treatment at scale, we surveyed 765 rural households with ADPs across five of 25 Cambodian provinces. Response frequencies, descriptive statistics, and regressions with five multi-factor indices that describe households’ practices and attitudes related to ADPs and ultimately safe FS treatment were calculated. Despite training at the time of purchase, three in five households did not recall how long treatment must proceed until emptying can be performed safely, and no household actually waited the recommended two years to empty their pits. While households appreciated the advantages of owning an ADP, such as reduced costs and required land area compared to single-pit latrines over time, no household followed recommended treatment practices, which could have serious health and environmental implications. Household practices also varied by province, flood proneness, education, and other factors, adding complexity to how to mitigate these issues; for example, completing formal education surprisingly reduced compliance with recommended ADP practices. Household behaviors have a strong impact on the success of on-site sanitation systems in rural areas achieving sustained SMS. Increased access to affordable and safe emptying service providers could allow households to empty and switch the pits of their ADPs, and safely dispose of FS in-situ based on the duration of treatment. Household practices when operating on-site sanitation systems must also be considered when designing such systems and monitoring for SMS once such systems are installed.

Moral differences hinder communication and relationship formation. However, perceptions and reactions to moral dissimilarity varies. Accordingly, we explored how moral adaptiveness (a flexible application of morality) relates to the intent to communicate with and befriend morally dissimilar others by focusing on moral relativism (believing that morals are subjective) and moral tolerance (believing that one should not condemn/change dissimilar others). We observed adaptiveness’ relationships with the willingness to communicate (WTC) with morally dissimilar others and greater moral diversity in close friendship networks. Surveys of convenience samples of adults recruited through MTurk (Nstudy1 = 325; Nstudy2 = 1219) demonstrated partial evidence of a positive link between moral adaptiveness and WTC. By comparison, a consistent relationship between adaptiveness and the moral diversity of friendship networks did not emerge.
