Published: May 2020

Abstract
Background: We conducted this study to understand roles of community leaders on adolescents HIV and Sexual and Reproductive Health (SRH) rights in Mulanje-Malawi. We assessed how each role influence health seeking behaviour and improve SRH rights among adolescents from the local perspective. Methods: A qualitative study approach was used. We conducted 12 Focus Group Discussions (FGDs) and 17 Key Informant Interviews (KIIs) with community leaders. Purposive sampling technique was used to select study participants for both KIIs and FGDs. Random sampling technique was used to identify one Traditional Authority (TA) and 12 villages where FGDs were conducted. Inductive thematic content analysis was done guided by the study objectives to generate emerging themes. Results: Community leaders have many roles on adolescents HIV and SRH. These roles include advisory, encouragement, regulating and restricting cultural practices, formulating bye-laws and handling sexual abuse complaints. However, community leaders with religious affiliation have shown to have different views with those representing other institutions not affiliated to religion. In addition, the majority of community leaders indicated low level of knowledge on adolescent’s SRH rights. Conclusion: We suggest that the roles of community leaders differ depending on the position held and institution represented. Those community leaders not affiliated to religious can encourage certain behaviour in adolescents while those from religious background are discouraging it. Stakeholders involved in the fight against HIV and SRH rights should invest more on capacity building among the community leaders.

Abstract
Background: In patients with long-term indwelling bladder catheters, bacterial colonization is inevitable, leading to urinary tract infections or encrustations with subsequent catheter blockage. Currently, bladder irrigations are the most frequently used prophylactic means, but the best solution remains yet to be determined. In vitro studies demonstrate that polihexanide is a promising option for catheter irrigation, but no data about safety and tolerability exist.Methods: In a prospective observational study in patients with long-term (> 2 weeks) indwelling bladder catheter, a 0.02% polihexanide solution was used to rinse the catheter on five consecutive days. Adverse events, tolerability and vital signs were assessed before, during, after and at the end of the treatment period. Results: There was no serious adverse event in the study. A total of 28 adverse events (AEs) in 15 (46.88%) participants were experienced. Absolute changes in pain scores were not clinically relevant. No incidences of either flushing or sweating were found during instillation. Bladder spasms during instillation were reported in two cases during a single instillation. Mean pulse rates did not change by more than 3 beats per minute. Mean changes in body temperature did not exceed 0.12 °C. Clinically relevant changes in blood pressure were recorded for 3 patients.Conclusions: This is the first study to demonstrate that a 0.02% polihexanide solution can safely be used for catheter irrigation.

Abstract
Assessing public opinion towards tobacco policies is important, particularly when determining the possible direction of future public health policies. The aim of this study was to describe the implementation of tobacco retailer licensing systems by state and territory governments in Australia, and to use the National Drug Strategy Household Survey (NDSHS) to assess levels of public support for a retailer licensing system in each jurisdiction over time and by a range of socio-demographic and behavioural attributes. National and state/territory estimates of public support for a tobacco retailer licensing system were derived as proportions using NDSHS data from 2004 to 2016. The effect of one’s jurisdiction of residence on the likelihood of supporting such an initiative in 2016 was assessed using logistic regression while controlling for various socio-demographic and behavioural characteristics. Public support for a tobacco retailer licensing system ranged from a high of 67.2% (95% CI 66.5% – 67.9%) nationally in 2007 and declined to 59.5% (95% CI 58.9% – 60.2%) in 2016. In 2016, support was greatest amongst those from Tasmania, those aged 50 years and older, females, those from the least disadvantaged areas, those living in major cities, never-smokers and never-drinkers. After adjusting for the socio-demographic and behavioural attributes of respondents, those from Queensland were significantly less likely to support a licensing system (adjusted OR = 0.85, 95% CI 0.77 – 0.94) compared to those from other jurisdictions, while those from Tasmania were significantly more likely to support a licensing system compared to those from other jurisdictions (adjusted OR = 1.29 , 95% CI 1.09 – 1.52). A clear majority of the public support a tobacco retailer licensing system, regardless of whether or not such a system is already in place in their jurisdiction of residence. Tobacco control initiatives other than a retailer licensing system may explain some of the residual variations in support observed between jurisdictions.

Abstract
Background Malaria is a major travel medicine issue. Retrospective confirmation of a malaria episode diagnosed in an endemic area can have relevant implications in trasfusional medicine in Europe, where blood donors are excluded from donation on the basis of positive malaria serology. However, there is scarce evidence on the dynamics of antimalarial antibodies after a first malaria episode in non immune individuals. First aim of this study was to describe the dynamics of antimalarial antibodies in a first malaria episode in non immune travellers. Secondary objectives were to assess the sensitivity of serology for a retrospective diagnosis in non immune travellers diagnosed while abroad and to discuss the implications in transfusional medicine. Methods Retrospective analysis of the results of an indirect fluorescence antibody test (IFAT) for malaria available for patients with a first malaria episode by Plasmodium falciparum and admitted at the IRCCS Sacro Cuore Don Calabria hospital in a 14-year period. The antibody titres were collected at baseline and during further follow up visits. Epidemiological, demographic and laboratory test results (including full blood count and malaria parasite density) were anonymously recorded in a study specific electronic Case Report Form created with OpenClinica software. Statistical analysis was performed with SAS software version 9.4. Results Thirty-six patients were included. Among them, all but two were Europeans (one African and one American). Median length of fever before diagnosis was two days (IQR 1-3). Thirty-five patients had seroconversion between day 1 and day 4 from admission, and the titre showed a sharply rising titre, often to a very high level in a few days. Only a single patient remained negative in the first 5 days from admission, after which he was no more tested. Six patients were followed up for at least two months, and they all showed a decline in IFAT titre, tending to seroreversion (confirmed in one patient with the longest follow up, almost four years). Conclusions Serology demonstrated reliable for retrospective diagnosis in non immune travellers. The decline in the antimalarial titre might be included in the screening algorithms of blood donors, but further studies are needed.

Abstract
Background: Adipose-derived mesenchymal stem cells ( ADMSCs ) have attracted widespread interest as cell-based tissue repair systems. To obtain adequate quantities of ADMSCs for therapeutic applications, extensive in vitro expansion is required. However, under current two-dimensional (2D) approaches , ADMSCs rapidly undergo replicative senescence , and cell growth is impeded and stem cell properties are eliminated by mechanisms that are poorly understood . These issues limit the extensive applications of ADMSCs . In this study, we investigated senescence-related changes in mesenchymal stem cells (MSCs) isolated from human adipose tissue in 2D and three-dimensional (3D) cultures. Methods: We studied cell growth over a given period (21 days) to determine if modes of culture were associated with ADMSCs senescence . ADMSCs were isolated from healthy females by liposuction surgery and then were grew in 2D and 3D cultures. The cell morphology was observed during cell culture. Every other time of culture, senescence-associated β-galactosidase (SA-β-gal) expression, cell viability, proliferation, and differentiation potential of ADMSCs from 2D and 3D cultures were detected. Also, senescence and stemness related genes expression, telomere length, telomerase activity, and energy metabolism of ADMSCs for different culture time were evaluated. Results: With long-term propagation, we observed significant changes in cell morphology, proliferation, differentiation abilities and energy metabolism, which were associated with increases in SA-β-gal activity, and decreases in telomere length and telomerase activity . Notably, when cultured in 3D, these changes were improved. Conclusions: Our results indicate that 3D culture is able to ameliorate senescence-related changes in ADMSCs.

Abstract
Background: Depression is one of the most prevalent emotional mental health problem among adolescents. Mental health problem might be the result of child maltreatment considering their prevalence are increasing simultaneously in Indonesia. The aim of this study is determining the association between depression and history of maltreatment among adolescents. Methods: An analytic cross-sectional study was conducted to 786 junior high school students of Bandung City, West Java, Indonesia. Subject was selected using two stage cluster sampling. The questionnaire of Children’s Depression Inventory (CDI) and ISPCAN Child Abuse Screening Tool (ICAST) were applied to assess depression and history of maltreatment respectively. Depression confirmation was diagnosed by psychiatry based on scored positive in CDI. Data were analyzed using chi-square and multiple regression test. Results: History of child maltreatment was associated with depressive disorder in adolescents (p = 0.03). All dimension of child maltreatment had significant association with depression (p <0.05). Psychological violence had the highest risk factor for the occurrence of depressive disorders (PR = 6.51), followed by violence exposure and physical violence. Sexual violence was not a common dimension of child maltreatment among students. The history of psychological violence had the strongest association with depression, which three times more likely to develop depression (POR = 3.302, p = 0.004)Conclusion: Psychological violence was proven as a strong risk factor in developing depression symptom for adolescents student. Early intervention to prevent maltreatment and its consequences is critical, as well.

Abstract
Background: The most common sites of recurrence after liver transplantation for hepatocellular carcinoma (HCC) have been reported to be the liver, lung, bone, and adrenal glands, but there have also been many reports of cases of multiple recurrence. The prognosis after recurrence is poor, with reported median survival after recurrence of HCC ranging from 9 to 19 months. Here, we report a case of long-term survival after recurrence of pharyngeal metastasis following living-donor liver transplantation (LDLT) for HCC within the Milan criteria, by resection of the metastatic region and cervical lymph node dissection. Case presentation: A 47-year-old man with a Model End-stage Liver Disease (MELD) score of 11 underwent LDLT for HCC within the Milan criteria for liver cirrhosis associated with hepatitis B virus infection, with his 48-year-old elder brother as the living donor. One year and 10 months after liver transplantation, he visited a nearby hospital with a chief complaint of discomfort on swallowing. A pedunculated polyp was found in the hypopharynx, and biopsy revealed HCC metastasis. We performed pharyngeal polypectomy. Two years later, cervical lymph nodes metastasis appeared, and neck lymph node dissection was performed. Although recurrence subsequently occurred three times in the grafted liver, the patient is still alive 12 years and 10 months after recurrence of pharyngeal metastasis. He is now a tumor-free outpatient taking sorafenib. Conclusion: It is necessary to recognize that the nasopharyngeal region is a potential site of HCC metastasis. Prognostic improvement can be expected with close follow-up, early detection, and multidisciplinary treatment, including radical resection.

Abstract
Background: The low genetic diversity of Upland cotton limits the potential for genetic improvement. Making full use of the genetic resources of Sea-island cotton will facilitate genetic improvement of widely cultivated Upland cotton varieties. The chromosome segments substitution lines (CSSLs) provide an ideal strategy for mapping quantitative trait loci (QTL) in interspecific hybridization.Results: In this study, a CSSL population was developed by PCR-based markers assisted selection (MAS), derived from the crossing and backcrossing of Gossypium hirsutum (Gh) and G. barbadense (Gb), firstly. Then, by whole genome re-sequencing, 11,653,661 high-quality single nucleotide polymorphisms (SNPs) were identified which ultimately constructed 1,211 recombination chromosome introgression segments from Gb. The sequencing-based physical map provided more accurate introgressions than the PCR-based markers. By exploiting CSSLs with mutant morphological traits, the genes responding for leaf shape and fuzz-less mutation in the Gb were identified. Based on a high-resolution recombination bin map to uncover genetic loci determining the phenotypic variance between Gh and Gb, 64 QTLs were identified for 14 agronomic traits with an interval length of 158 kb to 27 Mb. Surprisingly, multiple alleles of Gb showed extremely high value in enhancing cottonseed oil content (SOC). Conclusions: This study provides guidance for studying interspecific inheritance, especially breeding researchers, for future studies using the traditional PCR-based molecular markers and high-throughput re-sequencing technology in the study of CSSLs. Available resources include candidate position for controlling cotton quality and quantitative traits, and excellent breeding materials. Collectively, our results provide insights into the genetic effects of Gb alleles on the Gh, and provide guidance for the utilization of Gb alleles in interspecific breeding.
Biofilm formation on three different endotracheal tubes: a prospective clinical trial

Published: May 2020

Abstract
Background: Biofilm formation on endotracheal tubes (ETTs) is an early and frequent event in mechanically ventilated patients. The biofilm is believed to act as a reservoir for infecting microorganisms and thereby, contribute to development and relapses of ventilator-associated pneumonia (VAP). Once a biofilm has formed on an ETT surface, it is difficult to eradicate. This clinical study aimed to compare biofilm formation on three widely used ETTs with different surface properties and to explore factors potentially predictive of biofilm formation.Methods: We compared the grade of biofilm formation on ETTs made of uncoated polyvinyl chloride (PVC), silicone-coated PVC, and PVC coated with noble metals after > 24 hours of mechanical ventilation in critically ill patients. The comparison was based on scanning electron microscopy of ETT surfaces, biofilm grading, surveillance and biofilm cultures, and occurrence of VAP.Results: High-grade (score ≥ 7) biofilm formation on the ETTs was associated with development of VAP (OR 4.17 [95% CI 1.14–15.3], p = 0.031). Compared to uncoated PVC ETTs, the silicone-coated and noble-metal-coated PVC ETTs were independently associated with reduced high-grade biofilm formation (OR 0.18 [95% CI 0.06–0.59], p = 0.005 and OR 0.34 [95% CI 0.13–0.93], p = 0.036, respectively). No significant difference was observed between silicon-coated ETTs and noble-metal-coated ETTs (OR 0.54 [95% CI 0.17–1.65] p = 0.278). The microbes found in the ETT biofilm were frequently found in surveillance cultures at intubation and often remained in the biofilm despite appropriate antibiotic therapy. High-grade biofilm formation on ETTs was not predicted by either colonization with common VAP pathogens in surveillance cultures or duration of invasive ventilation.Conclusion: High-grade biofilm formation on ETTs was associated with development of VAP. Compared to the uncoated PVC ETTs, the silicone-coated and noble-metal coated PVC ETTs were independently associated with reduced high-grade biofilm formation. Methods aimed at the continuous monitoring of biofilm formation are warranted. Routines for biofilm removal need further study.Trial registration: ClinicalTrials.gov, NCT02284438.

Tectonic plates in 3D mantle convection model with stress- history-dependent rheology

Published: May 2020

Abstract
Plate tectonics is a key feature of the dynamics of the Earth’s mantle. By taking into account the stress-history-dependent rheology of mantle materials, we succeeded in realistically producing tectonic plates in our numerical model of mantle convection in a three-dimensional rectangular box. The calculated lithosphere is separated into several pieces (tectonic plates) that rigidly move. Deformation of the lithosphere caused by the relative motion of adjacent plates is concentrated in narrow bands (plate margins) where the viscosity is substantially reduced. The plate margins develop when the stress exceeds a threshold and the lithosphere is ruptured. Once formed, the plate margins persist, even after the stress is reduced below the threshold, allowing the plates to stably move over geologic time. The vertical component of vorticity takes a large value in the narrow plate margins. Secondary convection occurs beneath old tectonic plates as two-dimensional rolls with their axes aligned to the direction of plate motion. The surface heat ﬂow decreases with increasing distance from divergent plate margins (ridges) in their vicinity in the way the cooling half-space model predicts, but it tends towards a constant value away from ridges as observed for the Earth because of the heat transport by the secondary convection.

Abstract
Background: Meaning in life (MiL) is considered to be an important part of health and is associated with many positive outcomes in older adults, such as quality of life and longevity. As health promotors, nurses may take patients’ MiL into account in the care process. There is a knowledge gap in terms of what constitutes good care in relation to older patients’ MiL, and what the benefits may be for patients when nursing is attuned to this aspect. The purpose of this study was to explore the experiences of home nursing older adults in relation to nurses’ attunement to MiL. Methods: Gadamerian hermeneutic phenomenological design with semi-structured interviews. Participants were 24 aged home nursing patients. A framework of care ethical evaluation was used in the analysis. Multiple dialogues enhanced understanding. Results: Patients did not expect nurses’ regard for their MiL. They rather expected ‘normal contact’ and adequate physical care. Nurses showed that they were open to patients’ MiL by being interested in the patient as a person and by being attentive to specific and hidden needs. Participants explained that the nurse’s behaviour upon arrival set the tone: they knew immediately if there was room for MiL or not. All participants had positive and negative experiences with nurses’ behaviour in relation to MiL. Valued nursing care included maintaining a long, kind and reciprocal relationship; doing what was needed; and skilled personalised care. Participants mentioned ‘special ones’: nurses who attuned to them in a special way and did more than expected. Benefits of care that was attuned to patients’ MiL were: experiencing a cheerful moment, feeling secure, feeling like a valuable person and having a good day. Older adults also stressed that consideration for MiL helps identify what is important in healthcare. Conclusion: Aged homecare patients value nurses’ attunement to their MiL positively. Although patients regard MiL mostly as their own quest, nurses play a modest yet important role. Managers and educators should support nurses’ investment in reciprocal nurse-patient relationships.
