Abstract
Background: There are considerable benefits of point-of-use water chlorination programmes in emergencies but remaining challenges include lack of standard dosing recommendations for water treatment, inappropriate chlorination technologies, and limited published evaluations. We conducted a small-scale before-and-after field trial to assess the accuracy and consistency of an automated chlorinator named Zimba in camps housing forcibly displaced Myanmar nationals (FDMN), Cox's Bazar.
Methods: From August-September 2018, we selected two shallow tubewells [one with high (6.5 mg/L) and one with low (1.5 mg/L) iron concentration), and enrolled 20 households (10 having access to each tubewell) to participate in household surveys and water sampling. At baseline, field-team tested tubewell, and household stored water for iron, turbidity, free and total chlorine from using digital field-test kits. At baseline, the team collected water samples from selected tubewells (N=2), from Zimba chlorinators immediately after chlorination. (N=8) and household stored drinking water (N=20). Over four weeks, they collected post-treated water stored in household vessels (N=84), and post-treated household stored water in a project provided safe storage container (N=15). Water samples were tested for E. coli.
Results: At baseline, 12 (60%) samples of water stored in household vessels were contaminated with E. coli (mean log10 E. coli=0.62 MPN/100mL). After installing the Zimba, all water samples (100%) collected immediately after chlorination and project provided safe storage containers were free from E. coli, but 41% of post-treated water stored in household were contaminated with at least one E. coli/100mL. Log10 mean E. coli concentrations storage containers water stored in household vessels at baseline were similar to the post-treated water stored in the household vessels. E. coli concentrations were significantly lower in the project-provided safe storage containers [(log10 mean difference=0.92 MPN, 95% CI 0.59-1.14)] compared to baseline and to post-treated water stored in household vessels [(log10 mean difference=0.57 MPN, 95% CI 0.32-0.83)].
Conclusions: The Zimba is a potential water treatment technology for groundwater extracted through tubewells with different iron concentrations in humanitarian settings. Future research should address the low chlorine residual in household stored water and its impact on water contamination.

Authors: Kim Soo-Yeon , Kim Ah Rim 
Published: February 2021

Abstract
Background: Schizophrenia requires a community-based intervention approach combined with standard treatment to prevent relapses. A literature review is required to understand the effectiveness of community-based interventions and to enhance quality in countries where they have not been fully established. This is a protocol for a systematic review of the effectiveness of community-based interventions for patients with schizophrenia spectrum disorders. Methods: Studies on community-based interventions for patients with schizophrenia spectrum disorders that were published any time until January 2021 will be searched in six databases, using the primary words: “schizophrenia” and “community mental health services.” The comparison groups will include patients with schizophrenia spectrum disorders who are only receiving the usual care and those who also receive community-based interventions. The schizophrenia spectrum disorders referred to in this study are defined according to the DSM-5; delusional disorders, schizophrenic disorders, and schizoaffective disorder will be included. Relapse/re-hospitalization rates (primary outcome) and quality of life (secondary outcome) will be identified for each group. The study design will consider only randomized controlled trials (RCT). To assess bias, RCTs will be analyzed via the Cochrane RoB 2.0. Results will be descriptively synthesized and statistically analyzed, and will be structured according to patients’ characteristics, intervention type and exposure, and outcome type. Discrete variables will be calculated via odds ratio, and continuous variables will be calculated via standardized mean difference using RevMan 5.3 software. Discussion: We will provide a summary of the available evidence on the effectiveness of community-based interventions and specific guidelines to improve their outcomes. Systematic review registration: The protocol for this systematic review was registered on PROSPERO database; https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42019145660.

Published: February 2021

Abstract
Background: Prophylactic use of abdominal drain in gastrectomy has been questioned in the last 15 years and a 2015 Cochrane meta-analysis on four RCTs concluded that there was no convincing evidence to the routine drain placement in gastrectomy. Nevertheless, the Authors evidenced the moderate/low quality of the included studies and highlighted how 3 out of 4 came from Eastern countries. After 2015 only retrospective studies have been published, all with inconsistent results.Methods: ADiGe (Abdominal Drain in GastrEctomy) Trial is a multicenter prospective randomized non-inferiority trial with a parallel design. It aimed to verify whether avoiding routine use of abdominal drain is burdened with complications, particularly an increase in postoperative invasive procedures. Patients with gastric cancer, scheduled for subtotal or total gastrectomy with curative intent, are eligible for inclusion, irrespective of previous oncological treatment. The primary composite endpoint is reoperation or percutaneous drainage procedures within 30 postoperative days. The primary analysis will verify whether the incidence of the primary composite endpoint is higher in the experimental arm, avoiding routine drain placement, than control arm, undergoing prophylactic drain placement, in order to falsify or support the null hypothesis of inferiority. Secondary endpoints assessed for superiority are overall morbidity and mortality, Comprehensive Complications Index, incidence and time for diagnosis of anastomotic and duodenal leaks, length of hospital stay, readmission rate.Assuming one-sided alpha of 5%, and cumulative incidence of the primary composite endpoint of 6.4% in control arm and 4.2% in the experimental one, 364 patients allow to achieve 80% power to detect a non-inferiority margin difference between the arm proportions of 3.6%. Considering a 10% drop-out rate, 404 patients are needed. In order to have a balanced percentage between total and subtotal gastrectomy, recruitment will end at 202 patients for each type of gastrectomy. The surgeon and the patient are blinded until the end of the operation, while postoperative course is not blinded to patient and caregivers.Discussion: ADiGe Trial could contribute to critically re-evaluate the role of prophylactic drain in gastrectomy, a still widely used procedure.Trial registration: Prospectively registered (last updated on October 29, 2020) at Clinicaltrials.gov with the identifier NCT04227951, https://clinicaltrials.gov/ct2/show/NCT04227951.

Abstract
Background: N95 respiratory protection masks are used by healthcare professionals to prevent contamination from infectious microorganisms transmitted by droplets or aerosols.Methods: We conducted a rapid review of the literature analyzing the effectiveness of decontamination methods for mask reuse. The database searches were carried out up to September 2020. The systematic review was conducted in a way which simplified the stages of a complete systematic review, due to the worldwide necessity on reliable fast evidences on this matter.Results: A total of 563 articles were retrieved of which 48 laboratory-based studies were selected. Fifteen decontamination methods were included in the studies. A total of 19 laboratory studies used Hydrogen peroxide, 21 studies used ultraviolet germicidal irradiation,4 studies used ethylene oxide, 11 studies used dry heat, 9 studies used moist heat, 5 studies used ethanol, two studies used isopropanol solution, 11 studies used microwave oven, 10 studies used sodium hypochlorite, seven studies used autoclave, three studies used electric rice cooker, one study used cleaning wipes, one study used bar soap, one study used water, one study used multi-purpose high-level disinfection cabinet and another one used chlorine dioxide. Five methods promising: hydrogen peroxide vapor, ultraviolet irradiation, dry heat, wet heat/pasteurization, and microwave ovens.Conclusions: We have presented the best available evidence on masks decontamination, nevertheless, its applicability are limited due to few studies on the topic and lack of studies on real environments.

Abstract
Background: Graphene oxide (GO), a novel carbon-based nanomaterial, has promising applications in biomedicine. However, it induces potential cytotoxic effects on the gastrointestinal (GI) tract cells, and these effects have been largely uncharacterized. The present study aimed to explore the toxic effects of GO on the intestinal tract especially under pre-existing inflammatory conditions, such as inflammatory bowel disease (IBD), and elucidate underlying mechanisms.Results: Our findings indicated that oral gavage of GO worsened acute colitis induced by 2.5% dextran sodium sulfate (DSS) in mice. In vitro, GO exacerbated DSS-induced inflammation and apoptosis in the FHC cell line, an ideal model of intestinal epithelial cells (IECs). Further, the potential mechanism underlying GO aggravated mice colitis and cell inflammation was explored. Our results revealed that GO treatment triggered apoptosis in FHC cells through the activation of reactive oxygen species (ROS)/AMP-activated protein kinase (AMPK)/p53 pathway, as evidenced by the upregulation of cytochrome c (Cytc), Bax, and cleaved caspase-3 (c-cas3) and the downregulation of Bcl-2. Interestingly, pretreatment with an antioxidant, N-acetyl-L-cysteine, and a specific inhibitor of AMPK activation, Compound C (Com.C), effectively inhibited GO-induced apoptosis in FHC cells.Conclusions: Our data demonstrate that GO-induced IECs apoptosis via ROS/AMPK/p53 pathway activation accounts for the exacerbation of colitis in vivo and aggravation of inflammation in vitro. These findings provide a new insight into the pathogenesis of IBD induced by environmental factors. Furthermore, our findings enhance our understanding of GO as a potential environmental toxin, which helps delineate the risk of exposure to patients with disturbed intestinal epithelial barrier/inflammatory disorders such as IBD.

Published: February 2021

Abstract
Background: Trauma is the leading cause of death in people under 40 years of age worldwide. Various studies have been conducted focused on reducing the annual mortality rate due to trauma. One of the most important measures is reducing the time between the incident and the treatment set up, therefore estimation of the severity of trauma and progressing to mortality before further evaluation is justified. Numerous trauma scoring systems have been apllied worldwide as models for predicting mortality of trauma patients in short and long term periods based on clinical and laboratory data. In this study we aim to compare different trauma scoring systems (such as GAP, MGAP, RTS, TRISS) with a relatively new model – Shiraz Trauma Transfusion Score (STTS) – and to discribe the best qualities of these scoring systems for trauma patients in short (less than 24 hours) and long (more than 24 hours) term.Methods: In this cross-sectional study, data from hospitalized trauma patients in Rajaei hospital (center B) of Shiraz, Iran from May to November 2016 were collected and analyzed. Collected data consisted of age, sex, hospital admission duration, mechanism of trauma along with clinical data for calculating different trauma scoring systems, were recorded. Results: while RTS and STTS were the best predictors of mortality in trauma patients in the first 24 hours (sensitivity of 100.00%), GAP and MGAP were the best predictors of the patients’ survival (specificity of 93.83% and 92.59%). GAP and ISS were the best predictors of mortality in trauma patients for more than 24 hours (sensitivity of 82.02%). On the other hand, TRIS and RTS was the best predictors of patients' survival (specificity of 82.59% and 80.26%).Conclusions: Our study findings suggest that the utility and applicability of Shiraz Trauma Transfusion Score(STTS) in predicting mortality is not only comparable with other commonly used scoring methods but it may be of more value in short term mortality prediction.

Published: February 2021

Abstract
BACKGROUND: Early breastfeeding cessation is a societal concern given the massive benefits associated with breastfeeding for mother and child. More effective interventions are needed to increase breastfeeding duration. Prior to developing such interventions more research is needed to examine breastfeeding supports and barriers from the perspective of breastfeeding stakeholders. One such framework that can be utilized is the Socio-Ecological Model which stems from Urie Broffenbrenner’s early theoretical frameworks (1973-1979). The purpose of this study was to examine supports and barriers to breastfeeding across environmental systems. METHODS: A total of 49 representatives participated in a telephonic interview. Interviewees represented various levels of the model based on their current breastfeeding experience (i.e., mother or significant other) or occupation. A direct content analysis was performed as well as a constant comparative analysis to determine differences between level representatives. RESULTS: Common supports identified by all interviewees were in-hospital breastfeeding education (organizational level) and the existence of breastfeeding protection legislation (policy level). Barriers identified by all interviewees included a lack of support (interpersonal level), lack of hospital resources (organizational level) and lack of specificity within the existing breastfeeding protection legislation (policy level). Other identified supports and barriers varied by representatives for each level of the model. CONCLUSION: Future efforts should target multiple levels of the SEM to eliminate the disparities between breastfeeding mothers’ perceptions and the stakeholders working to increase breastfeeding initiation and duration rate.

Abstract
Background: Globally, very preterm birth is a health concern leading to various developmental difficulties such as poor motor and/or cognitive function. For infants born very preterm, Family-Centered Care (FCC) might promote developmental skills over the time in an appropriate enriched environment. The purpose of this study is to systematically review and assess the evidence of FCC interventions on the motor and neurobehavioral development in very preterm infants. Additionally, this review aims to determine the factors that might affect infant development.Methods: Systematic review will be carried out by including a) quasi-randomized controlled trials and randomized controlled trials b) of very preterm born infants (born < 32 weeks of gestation) and their primary caregivers will be included in the review c) who received FCC based interventions such as collaborative interaction between a healthcare professional and a parent, home program, home visits, and parent education and d) measure motor and neurobehavioral function. Electronic databases such as Scopus, PubMed, EMBASE, Cochrane Library, Web of Science, CINAHL, and PsycINFO will be searched using database-specific terms. Additionally, searches will be carried out in ProQuest, and references of included studies will be searched. Two review authors, independently, will conduct the screening, data extraction, and critical appraisal of included studies. If possible, a meta-analysis will be undertaken to assess the effect of the FCC on the motor and neurobehavior of premature infants.Conclusion: The review will provide insights regarding the effect of the FCC on preterm infants. This systematic review will guide the clinicians on the feasibility of practicing FCC that might support and promote the integration of parents into various rehabilitation settings.Systematic review registration: Protocol has been registered in PROSPERO on August 26, 2020.
Hsp90 modulates human sperm capacitation via the Erk1/2 and p38 MAPK signaling pathways

Published: February 2021

Abstract
Background: Heat shock protein 90 (Hsp90) is a highly abundant eukaryotic molecular chaperone that plays important roles in client protein maturation, protein folding and degradation, and signal transduction. Previously, we found that both Hsp90 and its co-chaperone cell division cycle protein 37 (Cdc37) were expressed in human sperm. Hsp90 is known to be involved in human sperm capacitation via unknown underlying mechanism(s). As Cdc37 was a kinase-specific co-chaperone of Hsp90, Hsp90 may regulate human sperm capacitation via other kinases. It has been reported that two major mitogen-activated protein kinases (MAPKs), extracellular signal-regulated kinase 1/2 (Erk1/2) and p38, are expressed in human sperm in the same locations as Hsp90 and Cdc37. Phosphorylated Erk1/2 has been shown to promote sperm hyperactivated motility and acrosome reaction, while phosphorylated p38 inhibits sperm motility. Therefore, in this study we explored whether Hsp90 modulates human sperm capacitation via the Erk1/2 and p38 MAPK signaling pathways. Methods: Human sperm was treated with the Hsp90-specific inhibitor 17-allylamino-17-demethoxygeldanamycin (17-AAG) during capacitation. Computer-assisted sperm analyzer (CASA) was used to detect sperm motility and hyperactivation. The sperm acrosome reaction was analyzed by using fluorescein isothiocyanate-conjugated Pisum sativum agglutinin (PSA-FITC) staining. The interactions between Hsp90, Cdc37, Erk1/2 and p38 were assessed using co-immunoprecipitation (Co-IP) experiments. Western blotting analysis was used to evaluate the levels of protein expression and phosphorylation. Results: Human sperm hyperactivation and acrosome reaction were inhibited by 17-AAG, suggesting that Hsp90 is involved in human sperm capacitation. In addition, Co-IP experiments revealed that 17-AAG reduced the interaction between Hsp90 and Cdc37, leading to the dissociation of Erk1/2 from the Hsp90-Cdc37 protein complex. Western blotting analysis revealed that levels of Erk1/2 and its phosphorylated form were subsequently decreased. Decreasing of Hsp90-Cdc37 complex also affected the interaction between Hsp90 and p38. Nevertheless, p38 dissociated from the Hsp90 protein complex and was activated by autophosphorylation. Conclusions: Taken together, our findings indicate that Hsp90 is involved in human sperm hyperactivation and acrosome reaction. In particular, Hsp90 and its co-chaperone Cdc37 form a protein complex with Erk1/2 and p38 to regulate their kinase activity. These results suggest that Hsp90 regulates human sperm capacitation via the Erk1/2 and p38 MAPK signaling pathways.
Reclaiming Identity: Women, Social Exclusion, and Resistance in Bumi Manusia
Authors: Sofi Muhammad Jauhari , Basiri Nasim 
Published: February 2021

This paper aims to unveil the gender-based prejudice and the colonial state's policies that systematically exclude Native women by considering Pramoedya A. Toer's Bumi Manusia. It focuses on how women are excluded from useful social life participation and resist such unfair treatment to reclaim their own identity. A close textual analysis with postcolonial and feminist discourses was used in this literary study to interpret particular feelings, experiences, and events in the novel. After a comprehensive examination, the study found that women during the Dutch occupation in Java were denied their rights, freedom, and opportunities crucial to their social integration; they had to live their lives according to the interests of the ruling classes, i.e., the men and the white Europeans. Various forms of resistance, ranging from the lowest opposition mode to open rebellions, have been articulated as a response to the said social exclusion. In this sense, the novel exposes a female character that can take on a new form of existence. The insights gained from this study might be of assistance to confirm the awakening of women's conscious­ness in struggling against the oppressive power of sexism and racism in early twentieth century Java.

Abstract
In this research, effect of productive stages in nitrogen and phosphorus excretion in wastewater from hyperintensive tilapia (Oreochromis niloticus) culture was evaluated. Fish were cultivated considering three development stages (fingerling of 1.79 g, juvenile of 36.13 g, and adult of 72.96 g). Nitrite, nitrate, ammonium, and phosphorus concentration were determined in order to know the amount of nutrients excreted per productive stage of the fish at a high stocking density. Biometric data were recorded during the experiment with the purpose of determining the growth behavior of fish, as well as the measurement of the aerobic metabolism. Results showed that survival, growth, and health of fish are not affected by hyperdensity of culture; as well, combined catabolism of proteins and lipids was presented as substrates for energy with value for O:N ratio ranging between 20 and 60. In addition, higher concentration in excretion of nitrogen compounds and phosphorus per gram of fish was recorded in wastewater from a hyperintensive culture in fingerlings than in juveniles and adults. These results suggest the use of this wastewater in the early stages of fish growth, aiming to enhance sustainable systems with maximum use of the resources, such as aquaponics systems.
