Orientation: Research indicates that personality strengths and weaknesses can be a good starting point in reducing burnout risk and the resulting somatic symptoms that lower employee health and organisational outcomes. Research purpose: The current study investigated the relationship between burnout, personality traits, and somatic symptoms in a South African sample. Motivation for the study: Despite burnout’s influence on employee health and organisational outcomes, no study has been conducted within the South African context investigating these phenomena together. Knowledge of the specific personality traits that increase burnout risk and somatic symptoms is essential, as it can help create interventions to prevent and lower burnout risk for South African employees. Research approach/design and method: A quantitative cross-sectional design was followed by a purposive sample (N = 249) of South African employees who were at least 18 years old. They completed a short form Big Five personality traits and the Burnout Assessment Tool. Main findings: The results indicate a strong link between burnout and somatic symptoms, but that increased emotional stability and openness lowered burnout risk. Extraversion and emotional stability also lowered employees’ experiences of somatic symptoms, whereas conscientiousness increased somatic symptoms. Practical/managerial implications: The results inform South African organisations on possible personality traits that increase burnout risk and can inform practice and create interventions and training for employees. Contribution/value-add: The results contribute to burnout research in South Africa and create a basis for future research.

IntroductionContradictions remain on the impact of interhospital competition on the quality of care, mainly the mortality. The aim of the study is to evaluate the impact of interhospital competition on postoperative mortality after surgery for colorectal cancer in France.MethodsWe conducted a retrospective cross-sectional study from 2015 to 2019. Data were collected from a National Health Database. Patients operated on for colorectal cancer in a hospital in mainland France were included. Competition was measured using number of competitors by distance-based approach. A mixed-effect model was carried out to test the link between competition and mortality.ResultsNinety-five percent (n = 152,235) of the 160,909 people operated on for colorectal cancer were included in our study. The mean age of patients was 70.4 ±12.2 years old, and female were more represented (55%). A total of 726 hospitals met the criteria for inclusion in our study. Mortality at 30 days was 3.6% and we found that the mortality decreases with increasing of the hospital activity. Using the number of competitors per distance method, our study showed that a "highly competitive" and "moderately competitive" markets decreased mortality by 31% [OR: 0.69 (0.59, 0.80); p per year) was also associated to lower mortality rate [OR: 0.74 (0.63, 0.86); pConclusionsThe results of our studies show that increasing hospital competition independently decreases the 30-day mortality rate after colorectal cancer surgery. Hospital caseload, patients' characteristics and age also impact the post-operative mortality.

Developments in remarriage and divorce have led to an influx of research on stepfamilies. However, previous studies show that the experiences of stepmothers are underreported. Therefore, a scoping review of the currently available academic literature (2012–2022) on stepmother experiences was conducted to identify the way forward for future research. A final sample of 11 articles indicate that stepmother research is mainly WEIRD and qualitative. Stepmothers reportedly experience ambivalent emotions which they often deal with silently, whilst navigating ambiguous stepmother roles with possibly limited support or acknowledgement under the wicked stepmother stereotype. Counselling and research are encouraged to assist this forgotten member of the stepfamily. Gaps in research and further research opportunities are identified.

Abstract Background Despite therapeutic advances, lung cancer remains the first cause of death from cancer. The main objective of this study was to identify risk factors associated with death within 3‐months of the first hospitalization for lung cancer in France. Methods This analysis included patients with a first hospitalization for lung cancer (between January 1, 2016 and December 31, 2018) according to diagnosis‐related groups entered into the French national medical‐administrative database. Clinical and socioeconomic parameters and characteristics of that first hospitalization were analyzed. A model predictive of early mortality was developed based on those variables. Results The 144,087 included patients were 67% men; median age of 68 [interquartile range 60–76] years; 47% had metastatic disease at diagnosis; and 34% and 23%, respectively, had received systemic treatment or undergone curative surgery. The 3‐month mortality was 19%, and significantly higher for those ≥70 versus 30 days (OR, 1.58 1.49–1.68). In contrast, no socioeconomic characteristic was associated with early mortality. Conclusion Almost 1 in 5 patients diagnosed with lung cancer in France died within 3 months post‐diagnosis. Improving survival requires diagnosis at an earlier stage and better organization of diagnosis and specific care pathways.

IntroductionThe series of electrocardiograms (ECGs) can help track cardiac abnormalities in patients’ conditions and make an earlier clinical decision. It is crucial for nurses working in critical care environments to acquire ECG knowledge for effective ECG monitoring and act accordingly in case of a change in patient condition. This study aimed at investigating intensive care unit (ICU) nurses’ knowledge and attitude towards ECG interpretation in Fujian province, China. The study also analyzed the relationship between participants’ demographic characteristics and level of ECG knowledge.MethodsThis study was done online at twenty-one hospitals in Fujian province using a quantitative cross-sectional design involving 357 registered nurses working in the ICU between October and December 2021. The selection of hospitals and potential participants involved purposive and convenient sampling methods, respectively. Binary logistic regression was carried out to determine factors that predict ICU nurses’ knowledge of ECG interpretation, and a p-value

Abstract Background Upsurge in cardiopulmonary dysfunctions in Enugu, Nigeria, involved mainly cement workers, automobile spray painters, woodworkers, and Cleaners and was worsened in the dry season, suggesting the need for an occupation-specific characterization of the disease features and seasonal evaluation of air quality for prevention and management. Methods We conducted a randomized cross-sectional study of eighty consenting participants (in Achara Layout, Enugu), comprising 20 cement workers (39.50 ± 14.95 years), 20 automobile spray painters (40.75 ± 9.85 years), 20 woodworkers (52.20 ± 9.77 years), and 20 cleaners (42.30 ± 9.06 years). The air quality, some haematological (fibrinogen-Fc, and C-reactive protein-CRP), and cardiopulmonary parameters were measured and analyzed using ANCOVA, at p

One of the difficulties encountered in the designing of solar photovoltaic systems is to find a model that accurately reproduces the behaviour of the system under various production conditions. The accuracy of this model depends on the identified parameters which are mainly based on the optimization technique performed and the objective function employed. The algorithm used here is the equilibrium optimizer. This one allows to identify the decision variables of the one and two diodes models of the RTC France solar cell which will allow us to minimize the objective function. The optimization strategy used here is based on the experimental data which are measured under a known temperature and irradiation level. The root mean square error between the measured and estimated current data sets, which is widely used in the literature, is adapted to evaluate the effectiveness of the method. The results obtained by calculating the mean square error by the equilibrium optimizer method for each model, are then compared with those obtained by methods identified in the literature under the similar conditions. It is found that the presented method presents results that are the closest to the real behaviour of a photovoltaic solar cell. It presents a result that minimizes the objective function enormously. Thus, we evaluate for the model with one diode the mean square error to 9.8604E−4 and 9.83532E−4 for the model with two diodes. This method reproduces better the behaviour of a photovoltaic solar cell than other methods listed in the literature. Moreover it presents a fast convergence towards the optimal solution. This allows us to validate the algorithms presented here to estimate the parameters of a photovoltaic solar cell.

This work aims at reinforcing simultaneously the coefficient of performance (COP) and the exergetic coefficient of performance (ECOP), in order to improve the operation of an absorption chiller to be used in tropical areas. It uses a new method based on the determination of variable one-line matrix that allows to find the NH3 mass fraction of NH3-NaSCN solution on each branch of the system.This matrix is obtained by substitution between the empirical formulae of NH3 and NH3-NaSCN from two different approaches, with the aim of making the current model more simple and less complex than those commonly used by other researchers. The approach developed is a direct digital method, easy to implement and allowing to find and understand some hidden functions of the black boxes of several energy simulation softwares, such as the Engineering Solver Equation (EES). The modeling of the system is carried out in Matlab to predict the temperatures and mass flows that can upgrade the system. The purpose is to contribute to the improvement and commissioning of an absorption chiller operating at thermal comfort temperatures in two cities in Cameroon: Douala and Yaoundé. The results show that the temperatures in the generator, condenser and absorber for which the COP and ECOP are maximum are respectively [92°C; 100°C]; 35°C, and [35°C; 40.8°C], and those of the mass flow rates of the refrigerant leaving the generator and condenser are respectively [0.44 kg/s; 0.86 kg/s] and 0.98 kg/s. The evaporator does not show these remarks. The simulation results can be used for thermodynamic optimisation of the cooling capacity (CC) and reduction of electrical energy consumption of the current system.

Abstract Background Mentor mothers provide psychosocial and other support to pregnant and post-partum women living with HIV (WLHIV), which has been shown to enhance maternal-infant outcomes in the prevention of mother-to-child transmission of HIV (PMTCT). Our objective was to assess the acceptability of mentor mothers as a PMTCT intervention, and to explore opinions on mentor mother program composition and delivery among stakeholders in North-Central Nigeria. Methods We conducted nine focus group discussions and 31 in-depth interviews with 118 participants, including WLHIV, pregnant women, male partners, health workers, traditional birth attendants, community leaders, PMTCT program implementers, and policymakers. Participants were purposively recruited from health facilities and surrounding communities in the Federal Capital Territory and Nasarawa State. Transcripts were manually analysed using a Grounded Theory approach, where theory was derived from the data collected. Results Most participants were female (n = 78, 67%), and married (n = 110, 94%). All participant groups found mentor mothers acceptable as women providing care to pregnant and postpartum women, and as WLHIV supporting other WLHIV. Mentor mothers were uniquely relatable as role models for WLHIV because they were women, living with HIV, and had achieved an HIV-negative status for their HIV-exposed infants. Mentor mothers were recognized as playing major roles in maternal health education, HIV treatment initiation, adherence, and retention, HIV prevention for male partners and infants, and couple HIV disclosure. Most WLHIV preferred to receive mentor mothers’ services at health facilities rather than at home, due to concerns about HIV-related stigma and discrimination through association with mentor mothers. Key mentor mother needs were identified as training, remuneration, and validation as lay health workers. Conclusions Mentor mothers are an acceptable PMTCT intervention among stakeholders in North-Central Nigeria. However, stigma and discrimination for both mentor mothers and their clients remain a critical challenge, and mentor mother needs such as training, pay, and a sustainably supported niche in health systems require focused attention.

In a dynamic shift, lowering reliance on fossil fuels and greenhouse gas emissions is now a top goal. This is accomplished through expanding the usage of renewable energy. Solar photovoltaic (PV) energy is now more than ever at the heart of many cities’ policies. Improving the efficiency of PV systems is a current research goal. The key challenge in rectifying complex systems is to establish a model that correctly reproduces the system’s dynamic behaviour. The goal function and optimization method utilised are indicative of the model parameters’ correctness. This paper presents a mix of differential evolution (DE) and Harris hawk optimisation (HHO). The suggested technique estimates the parameter vector that minimises the objective function to the greatest extent possible. This is for the many diode models. The procedure is validated using experimental data acquired at a known temperature and irradiance. The root mean square error (RMSE) is used to assess the method’s effectiveness. A comparison is made between the objective function of the hybrid approach presented in this publication and previously authorised methods. The strategy utilised is as straightforward as many others stated in our predecessors’ publications, and this applies to both models analysed. When compared to the simple version of the Harris hawk optimizer, this approach allows for more experimentation.

The COVID-19 pandemic fast-tracked the remote-working trend and placed many employees in a unique situation: conducting work in the presence of household pets. Despite research on pet-friendly workplaces, little work is available on the impact pets may have on remote-working owners. A simultaneous multimethod study was conducted to explore the impact of pets on remote-working employees’ work-related exhaustion and job satisfaction. The current study reports on the qualitative findings of the multimethod study. Using purposive sampling data were collected from remote-working pet owners (n = 77) through an online survey. Qualitative content analysis shows that pets served as a social resource to remote workers and influenced participants’ willingness to continue remote working. Some remote workers also saw their pets as a demand. This study provides preliminary insight into pets’ role in job satisfaction and work-related exhaustion through social support.

Despite the importance and requirement of integrated reporting on human capital (HC), research indicates a lack of reporting frameworks and adequate disclosure in organization reports. Thus, a unique research opportunity is created for researchers to determine what is being presented in reports and how it correlates with human resource management. This article investigates HC reporting practices and proposes a risk reporting framework in support of corporate governance. A qualitative method utilizing qualitative document analysis was followed to analyze a purposive sample (n = 39) of Johannesburg Stock Exchange top 40 listed companies’ annual integrated reports of 2020. Overall, companies followed a widely accepted risk management approach, with inconsistencies in the phases and methods of reporting the risk management phases directed at HC. The magnitude of the risk to the companies is also not understood. The most commonly reported HC risks were employee growth and development, diversity and inclusion, career paths, and employee turnover and turnover intention. Employee work-related well-being was largely neglected. An interesting finding is that the reported risks were metrics-deprived. Current HC practices are backward-looking instead of forward-looking, and they are fragmented. Therefore, an HC reporting framework is suggested for future research that addresses the gaps in integrated reports.

Orientation: Articles from three African psychology journals were reviewed to indicate their use and reporting practices of convenience samples. Research purpose: Method-relevant sections of empirical research reports (qualitative, quantitative, mixed method, etc.) were categorised to establish current method use and reporting practices as well as the methodological standards of convenience sampling in three African psychology journals from 2018 to mid-2020. Motivation for the study: Convenience sampling is the most popularly used sampling method in psychology. However, little attention is paid to sampling composition and sampling methods in articles, which influences trustworthiness, generalisability and replication of results. Psychology is also experiencing criticism because of the lack of non-Western, educated, industrialised, rich and democratic (WEIRD) samples. Research approach/design and method: A systematised review design was followed to purposively collect and categorise articles that used convenience samples as a sampling approach (n = 139) from the South African Journal of Industrial Psychology, the South African Journal of Psychology and the Journal of Psychology in Africa. Main findings: General reporting practices included sample size, gender, country, sample source (e.g. university) and age. Other sample characteristics indicate that studies were primarily conducted with South Africans speaking Afrikaans or English. English was mainly used to collect data from primarily black (African) and white (Caucasian) racial groups. Participants were largely female from university or college. Some sample differences such as sample size were also noted between qualitative and quantitative research methods. African journals’ reporting practices of sample characteristics were found to include standards and frequencies similar to or higher than those of international journals. Practical/managerial implications: Journals should pay attention to their role in influencing the reporting practices and standards of convenience samples and consider incorporating the presented categories. Contribution/value-add: The use of convenience sampling in African psychology journals is presented along with the potential of African research to provide non-WEIRD samples in psychology. Recommendations for improving the use of this sampling method are highlighted.

BackgroundHIV is a major global public health challenge, claiming the lives of over 32 million people so far. The satisfaction of HIV-affected clients with the quality of their HIV services at treatment centres is crucial for quality improvement. This article assesses clients' satisfaction with different aspects of the overall care experience and seeks to determine if the type of health facility ownership is a predictor of satisfaction.MethodsA cross-sectional study involving 430 respondents was conducted between September and October 2019. Purposeful and convenient sampling techniques were used to select health facilities and potential respondents, respectively. A pre-tested, interviewer-administered questionnaire was used to collect data. Binary logistic regression was used to assess the association between type of health facility and clients' satisfaction based on the six assessed aspects of care, and p˂0.05 was considered statistically significant.ResultsThe general clients' satisfaction with HIV/AIDS services at care and treatment centres was 92.3%. Respondents from public health facilities were most satisfied with privacy and confidentiality (100%), physical environment (100%), counseling (99.5%) and drug availability (99.5%); respondents from private health facilities were most satisfied with the time spent in the facility (95.9%); while respondents from faith-based health facilities were most satisfied with staff-patient communication (99.2%). However, after adjusting for confounders, only one aspect of care, that of "time spent in the facility," showed significant association with the type of health facility.ConclusionGenerally, clients' satisfaction with HIV/AIDS services at care and treatment centres in the Ubungo District, Dar es Salaam was high. This finding should encourage health care providers to maintain high-quality services to sustain clients' satisfaction.

Orientation: Work-related research from the perspective of psychology journal publications is reviewed, indicating research topic trends and research method use. Research purpose: What psychology journals are publishing about work-related topics as well as how these topics are being investigated was indicated. The specific objectives of this study were to analyse what research methods are being used, how these methods are being used and for what topics in work-related research. Motivation for the study: The lack of studies that investigate the use of research methods and work-related study themes from the perspective of miscellaneous psychology journals prompted this study. Research approach/design and method: A systematised review design was followed based on data collected by a previous study. Work-related research articles (n = 73) from five top-tier international miscellaneous or general psychology journals (published between 2013 and 2017) were collected and categorised. Main findings: Quantitative methods, convenience samples, cross-sectional designs and questionnaires for data collection as well as analysis of variance were the most frequently used methodologies. Workplace relationships, job search quality and re-employment and work stress were the most frequently investigated topics. Practical/managerial implications: Researchers should pay attention to the areas that lack methodological transparency in their studies to address the replication crisis in psychology. Method use should be expanded beyond quantitative methods where applicable. Industrial and organisational psychologists are reminded of their identity as applied psychologists. Contribution/value-add: The use of research methods in work-related research published by psychology journals is presented. Trends for this sample as well as areas for improving the replication crisis in psychology were identified.

Research methods play an imperative role in research quality as well as educating young researchers, however, the application thereof is unclear which can be detrimental to the field of psychology. Therefore, this systematised review aimed to determine what research methods are being used, how these methods are being used and for what topics in the field. Our review of 999 articles from five journals over a period of 5 years indicated that psychology research is conducted in 10 topics via predominantly quantitative research methods. Of these 10 topics, social psychology was the most popular. The remainder of the conducted methodology is described. It was also found that articles lacked rigour and transparency in the used methodology which has implications for replicability. In conclusion this article, provides an overview of all reported methodologies used in a sample of psychology journals. It highlights the popularity and application of methods and designs throughout the article sample as well as an unexpected lack of rigour with regard to most aspects of methodology. Possible sample bias should be considered when interpreting the results of this study. It is recommended that future research should utilise the results of this study to determine the possible impact on the field of psychology as a science and to further investigation into the use of research methods. Results should prompt the following future research into: a lack or rigour and its implication on replication, the use of certain methods above others, publication bias and choice of sampling method.

BACKGROUND:Peer support provided by experienced and/or trained "expert" women living with HIV has been adopted by prevention of mother-to-child transmission of HIV (PMTCT) programs across sub-Saharan Africa. While there is ample data on HIV status disclosure among non-expert women, there is little data on disclosure among such expert women, who support other women living with HIV. OBJECTIVE:This study compared HIV disclosure rates between expert and non-expert mothers living with HIV, and contextualized quantitative findings with qualitative data from expert women. METHODS:We compared survey data on HIV disclosure to male partners and family/friends from 37 expert and 100 non-expert mothers living with HIV in rural North-Central Nigeria. Four focus group discussions with expert mothers provided further context on disclosure to male partners, extended family and peers. Chi square and Fisher's exact tests were applied to quantitative data. Qualitative data were manually analyzed using a Grounded Theory approach. RESULTS:Two-thirds of the 137 participants were 21-30 years old; 89.8% were married, and 52.3% had secondary-level education. Disclosure to male partners was higher among expert (100.0%) versus non-expert mothers (85.0%), p = 0.035. Disclosure to anyone (93.1% vs 80.8%, p = 0.156), and knowledge of male partners' HIV status were similar (75.7% versus 66.7%, p = 0.324) between expert and non-expert mothers, respectively. With respect to male partners, HIV serodiscordance rates were also similar (46.4% vs 55.6%, p = 0.433). Group discussions indicated that expert mothers did not consistently disclose to their mentored clients, with community-level stigma and discrimination stated as major reasons for this non-disclosure. CONCLUSIONS:Expert mothers experience similar disclosure barriers as their non-expert peers, especially regarding disclosure outside of intimate relationships. Thus, attention to expert mothers' coping skills and disclosure status, particularly to mentored clients is important to maximize the impact of peer support in PMTCT.

Biofilm formation is considered a major cause of therapeutic failure because bacteria in biofilms have higher protection against antimicrobials. Thus, biofilm-related infections are extremely challenging to treat and pose major concerns for public health, along with huge economic impacts. Pseudomonas aeruginosa, in particular, is a “critical priority” pathogen, responsible for severe infections, especially in cystic fibrosis patients because of its capacity to form resistant biofilms. Therefore, new therapeutic approaches are needed to complete the pipeline of molecules offering new targets and modes of action. Biofilm formation is mainly controlled by Quorum Sensing (QS), a communication system based on signaling molecules. In the present study, we employed a molecular docking approach (Autodock Vina) to assess two series of chromones-based compounds as possible ligands for PqsR, a LuxR-type receptor. Most compounds showed good predicted affinities for PqsR, higher than the PQS native ligand. Encouraged by these docking results, we synthesized a library of 34 direct and 25 retro chromone carboxamides using two optimized routes from 2-chromone carboxylic acid as starting material for both series. We evaluated the synthesized carboxamides for their ability to inhibit the biofilm formation of P. aeruginosa in vitro. Overall, results showed several chromone 2-carboxamides of the retro series are potent inhibitors of the formation of P. aeruginosa biofilms (16/25 compound with % inhibition ≥ 50% at 50 μM), without cytotoxicity on Vero cells (IC50 > 1.0 mM). The 2,4-dinitro-N-(4-oxo-4H-chromen-2-yl) benzamide (6n) was the most promising antibiofilm compound, with potential for hit to lead optimization.

Abstract Background HIV status disclosure to male partners is important for optimal outcomes in the prevention of mother-to-child transmission of HIV (PMTCT). Depending on timing of HIV diagnosis or pregnancy status, readiness to disclose and disclosure rates may differ among HIV-positive women. We sought to determine rates, patterns, and experiences of disclosure among Nigerian women along the PMTCT cascade. Methods HIV-positive women in rural North-Central Nigeria were purposively recruited according to their PMTCT cascade status: pregnant-newly HIV-diagnosed, pregnant-in care, postpartum, and lost-to-follow-up (LTFU). Participants were surveyed to determine rates of disclosure to male partners and others; in-depth interviews evaluated disclosure patterns and experiences. Tests of association were applied to quantitative data. Qualitative data were manually analysed by theme and content using the constant comparative method in a Grounded Theory approach. Results We interviewed 100 women; 69% were 21–30 years old, and 86% were married. There were 25, 26, 28 and 21 women in the newly-diagnosed, in-care, postpartum, and LTFU groups, respectively. Approximately 81% of all participants reported disclosing to anyone; however, family members were typically disclosed to first. Ultimately, more women had disclosed to male partners (85%) than to family members (55%). Rates of disclosure to anyone varied between groups: newly-diagnosed and LTFU women had the lowest (56%) and highest (100%) rates, respectively (p = 0.001). However, family (p = 0.402) and male partner (p = 0.218) disclosure rates were similar between cascade groups. Across all cascade groups, fear of divorce and intimate partner violence deterred women from disclosing to male partners. However, participants reported that with assistance from healthcare workers, disclosure and post-disclosure experiences were mostly positive. Conclusion In our study cohort, although disclosure to male partners was overall higher, family members appeared more approachable for initial disclosure. Across cascade groups, male partners were ultimately disclosed to at rates > 75%, with no significant inter-group differences. Fear appears to be a major reason for non-disclosure or delayed disclosure by women to male partners. Augmentation of healthcare workers’ skills and involvement can mediate gender power differentials, minimize fear and shorten time to male partner disclosure among women living with HIV, regardless of their PMTCT cascade status.

Abstract Background Adolescents living with HIV (ALHIV) have worse health outcomes than other populations of people living with HIV. Contributing factors include lack of standard and comprehensive procedures for ALHIV transitioning from pediatric to adult care. This has contributed to poor retention at, and following transition, which is problematic especially in high ALHIV-burden, resource-limited settings like Nigeria. Methods Using a two-arm cluster randomized control design, the Adolescent Coordinated Transition (ACT) trial will measure the comparative effectiveness of a graduated transition and organized support group intervention against the usual practice of abrupt transfer of Nigerian ALHIV from pediatric to adult care. This study will be conducted at 12 secondary and tertiary healthcare facilities (six intervention, six control) across all six of Nigeria’s geopolitical zones. The study population is 13- to 17-year-old ALHIV (N = 216, n = 108 per study arm) on antiretroviral therapy. Study participants will be followed through a 12-month pre-transfer/transition period and for an additional 24 months post transfer/transition. The primary outcome measure is the proportion of ALHIV retained in care at 12 and 24 months post transfer. Secondary outcome measures are proportions of ALHIV achieving viral suppression and demonstrating increased psychosocial wellbeing and self-efficacy measured by psychometric tests including health locus of control, functional social support, perceived mental health, and sexual risk and behavior. Discussion We hypothesize that the ACT intervention will significantly increase psychosocial wellbeing, retention in care and ultimately viral suppression among ALHIV. ACT’s findings have the potential to facilitate the development of standard guidelines for transitioning ALHIV and improving health outcomes in this population. The engagement of a consortium of local implementing partners under the Nigeria Implementation Science Alliance allows for nationwide study implementation and expedient results dissemination to program managers and policy-makers. Ultimately, ACT may also provide evidence to inform transitioning guidelines not only for ALHIV but for adolescents living with other chronic diseases in resource-limited settings.

Abstract Background Low rates of maternal healthcare service utilization, including facility delivery, may impede progress in the prevention of mother-to-child transmission of HIV (PMTCT) and in reducing maternal and infant mortality. The MoMent (Mother Mentor) study investigated the impact of structured peer support on early infant diagnosis presentation and postpartum maternal retention in PMTCT care in rural Nigeria. This paper describes baseline characteristics and correlates of facility delivery among MoMent study participants. Methods HIV-positive pregnant women were recruited at 20 rural Primary Healthcare Centers matched by antenatal care clinic volume, client HIV prevalence, and PMTCT service staffing. Baseline and delivery data were collected by participant interviews and medical record abstraction. Multivariate logistic regression with generalized estimating equation analysis was used to evaluate for correlates of facility delivery including exposure to structured (closely supervised Mentor Mother, intervention) vs unstructured (routine, control) peer support. Results Of 497 women enrolled, 352 (71%) were between 21 and 30 years old, 319 (64%) were Christian, 245 (49%) had received secondary or higher education, 402 (81%) were multigravidae and 299 (60%) newly HIV-diagnosed. Delivery data was available for 445 (90%) participants, and 276 (62%) of these women delivered at a health facility. Facility delivery did not differ by type of peer support; however, it was positively associated with secondary or greater education (aOR 1.9, CI 1.1–3.2) and Christian affiliation (OR 1.4, CI 1.0–2.0) and negatively associated with primigravidity (OR 0.5; 0.3–0.9) and new HIV diagnosis (OR 0.6, CI 0.4–0.9). Conclusions Primary-level or lesser-educated HIV-infected pregnant women and those newly-diagnosed and primigravid should be prioritized for interventions to improve facility delivery rates and ultimately, healthy outcomes. Incremental gains in facility delivery from structured peer support appear limited, however the impact of duration of pre-delivery support needs further investigation. Religious influences on facility delivery and on general maternal healthcare service utilization need to be further explored. Trial Registration ClinicalTrials.gov number NCT01936753 , registered September 2013.

INTRODUCTION:The period of transition from pediatric to adult care has been associated with poor health outcomes among 10-19 year old adolescents living with HIV (ALHIV). This has prompted a focus on the quality of transition services, especially in high ALHIV-burden countries. Due to lack of guidelines, there are no healthcare transition standards for Nigeria's estimated 240,000 ALHIV. We conducted a nationwide survey to characterize routine transition procedures for Nigerian ALHIV. MATERIALS AND METHODS:This cross-sectional survey was conducted at public healthcare facilities supported by five local HIV service implementing partners. Comprehensive HIV treatment facilities with ≥1 year of HIV service provision and ≥20 ALHIVs enrolled were selected. A structured questionnaire assessed availability of treatment, care and transition services for ALHIV. Transition was defined as a preparatory process catering to the medical, psychosocial, and educational needs of adolescents moving from pediatric to adult care. Comprehensive transition services were defined by 6 core elements: policy, tracking and monitoring, readiness evaluation, planning, transfer of care, and follow-up. RESULTS:All 152 eligible facilities were surveyed and comprised 106 (69.7%) secondary and 46 (30.3%) tertiary centers at which 17,662 ALHIV were enrolled. The majority (73, 48.3%) of the 151 facilities responding to the "clinic type" question were family-centered and saw all clients together regardless of age. Only 42 (27.8%) facilities had an adolescent-specific HIV clinic; 53 (35.1%) had separate pediatric/adolescent and adult HIV clinics, of which 39 (73.6%) reported having a transfer/transition policy. Only 6 (15.4%) of these 39 facilities reported having a written protocol. There was a bimodal peak at 15 and 18 years for age of ALHIV transfer to adult care. No surveyed facility met the study definition for comprehensive transition services. CONCLUSIONS:Facilities surveyed were more likely to have non-specialized HIV treatment services and had loosely-defined, abrupt transfer versus transition practices, which lacked the core transition elements. Evidence-based standards of transitional care tailored to non-specialized HIV treatment programs need to be established to optimize transition outcomes among ALHIV in Nigeria and in similar settings.

Compulsive buying behavior (CBB) has begun to be recognized as a condition worthy of attention by clinicians and researchers. Studies on the commonalities between CBB and other behavioral addictions such as gambling disorder (GD) exist in the literature, but additional research is needed to assess the frequency and clinical relevance of the comorbidity of CBB and GD. The aim of the study was to estimate the point-prevalence of CBB+GD in a clinical setting. Data corresponded to n=3,221 treatment-seeking patients who met criteria for CBB or GD at a public hospital unit specialized in treating behavioral addictions. Three groups were compared: only-CBB (n=127), only-GD (n=3,118) and comorbid CBB+GD (n=24). Prevalence for the co-occurrence of CBB+GD was 0.75%. In the stratum of patients with GD, GD+CBB comorbidity obtained relatively low point prevalence (0.77%), while in the subsample of CBB patients the estimated prevalence of comorbid GD was relatively high (18.9%). CBB+GD comorbidity was characterized by lower prevalence of single patients, higher risk of other behavioral addictions (sex, gaming or internet), older age and age of onset. CBB+GD registered a higher proportion of women compared to only-GD (37.5% vs. 10.0%) but a higher proportion of men compared to only-CBB (62.5% vs. 24.4%). Compared to only-GD patients, the simultaneous presence of CBB+GD was associated with increased psychopathology and dysfunctional levels of harm avoidance. This study provides empirical evidence to better understand CBB, GD and their co-occurrence. Future research should help delineate the processes through which people acquire and develop this comorbidity.

Aims: The primary objective of this study was to analyze the association between alcohol consumption and short-term response to treatment (post intervention) in male patients with gambling disorder enrolled in a group cognitive behavioral therapy (CBT) program.Methods: The sample consisted of 111 male individuals with a diagnosis of Gambling Disorder, with a mean age of 45 years (SD= 12.2). All participants were evaluated by a comprehensive assessment battery and assigned to CBT groups of 10-14 patients attending 16 weekly outpatient sessions lasting 90 min each.Results: The highest mean pre- and post-therapy differences were recorded for the alcohol risk/dependence group on the obsessive/compulsive and anxiety dimensions of the SCL-90-R. As regards the presence of relapses and dropouts over the course of the CBT sessions, the results show a significant association with moderate effect size: patients with risk consumption or alcohol dependence were more likely to present poor treatment outcomes.Conclusions: Alcohol abuse was frequent in GD, especially in patients with low family income and high accumulated debts. High levels of somatization and high overall psychopathology (measured by the SCL-90-R) were associated with increased risk of alcohol abuse. Alcohol abuse was also associated with poor response to treatment.

Foot-and-mouth disease (FMD) is a highly contagious disease which caused several large outbreaks in Europe in the last century. The last important outbreak in Switzerland took place in 1965/66 and affected more than 900 premises and more than 50,000 animals were slaughtered. Large scale emergency vaccination of the cattle and pig population has been applied to control the epidemic. In recent years, many studies have used infectious disease models to assess the impact of different disease control measures, including models developed for diseases exotic for the specific region of interest. Often, the absence of real outbreak data makes a validation of such models impossible. This study aimed to evaluate whether a spatial, stochastic simulation model (the Davis Animal Disease Simulation model) can predict the course of a Swiss FMD epidemic based on the available historic input data on population structure, contact rates, epidemiology of the virus and quality of the vaccine. In addition, the potential outcome of the 1965/66 FMD epidemic without application of vaccination was investigated. Comparing the model outcomes to reality, only the largest 10% of the simulated outbreaks approximated the number of animals being culled. However, the simulation model highly overestimated the number of culled premises. While the outbreak duration could not be well reproduced by the model compared to the 1965/66 epidemic, it was able to accurately estimate the size of the area infected. Without application of vaccination the model predicted a much higher mean number of culled animals than with vaccination, demonstrating that vaccination was likely crucial in disease control for the Swiss FMD outbreak in 1965/66. The study demonstrated the feasibility to analyze historical outbreak data with modern analytical tools. However, it also confirmed that predicted epidemics from a most carefully parametrized model cannot integrate all eventualities of a real epidemic. Therefore, decision makers need to be aware that infectious disease models are useful tools to support the decision making process but their results are not equal valuable as real observations and should always be interpreted with caution.

Background: Gambling disorder (GD) is characterized by a significant lack of self-control and is associated with impulsivity-related personality traits. It is also linked to deficits in emotional regulation and frequently co-occurs with anxiety and depression symptoms. There is also evidence that emotional dysregulation may play a mediatory role between GD and psychopathological symptomatology. Few studies have reported the outcomes of psychological interventions that specifically address these underlying processes. Objectives: To assess the utility of the Playmancer platform, a serious video game, as an additional therapy tool in a CBT intervention for GD, and to estimate pre-post changes in measures of impulsivity, anger expression and psychopathological symptomatology. Method: The sample comprised a single group of 16 male treatment-seeking individuals with severe GD diagnosis. Therapy intervention consisted of 16 group weekly CBT sessions and, concurrently, 10 additional weekly sessions of a serious video game. Pre-post treatment scores on South Oaks Gambling Screen (SOGS), Barratt Impulsiveness Scale (BIS-11), I7 Impulsiveness Questionnaire (I7), State-Trait Anger Expression Inventory 2 (STAXI-2), Symptom Checklist-Revised (SCL-90-R), State-Trait Anxiety Inventory (STAI-S-T), and Novelty Seeking from the Temperament and Character Inventory-Revised (TCI-R) were compared. Results: After the intervention, significant changes were observed in several measures of impulsivity, anger expression and other psychopathological symptoms. Dropout and relapse rates during treatment were similar to those described in the literature for CBT. Conclusion: Complementing CBT interventions for GD with a specific therapy approach like a serious video game might be helpful in addressing certain underlying factors which are usually difficult to change, including impulsivity and anger expression.

Pseudomonas putida strains are being developed as microbial production hosts for production of a range of amphiphilic and hydrophobic biochemicals. P. putida’s obligate aerobic growth thereby can be an economical and technical challenge because it requires constant rigorous aeration and often causes reactor foaming. Here, we engineered a strain of P. putida KT2440 that can produce phenazine redox-mediators from Pseudomonas aeruginosa to allow partial redox balancing with an electrode under oxygen-limited conditions. P. aeruginosa is known to employ its phenazine-type redox mediators for electron exchange with an anode in bioelectrochemical systems. We transferred the seven core phenazine biosynthesis genes phzA-G and the two specific genes phzM and phzS required for pyocyanin synthesis from P. aeruginosa on two inducible plasmids into P. putida KT2440. The best clone, P. putida pPhz, produced 45 mg/ L pyocyanin over 25 h of growth, which was visible as blue color formation and is comparable to the pyocyanin production of P. aeruginosa. This new strain was then characterized under different oxygen-limited conditions with electrochemical redox control and changes in central energy metabolism were evaluated in comparison to the unmodified P. putida KT2440. In the new strain, phenazine synthesis with supernatant concentrations up to 33 µg/ mL correlated linearly with the ability to discharge electrons to an anode, whereby phenazine-1-carboxylic acid served as the dominating redox mediator. P. putida pPhz sustained strongly oxygen-limited metabolism for up to 2 weeks at up to 12 µA/ cm² anodic current density. Together, this work lays a foundation for future oxygen-limited biocatalysis with P. putida strains.

How do university training and subsequent practical experience affect expertise in clinical psychology? To answer this question we developed methods to assess psychological knowledge and the competences to diagnose, construct case conceptualizations, and plan psychotherapeutic treatment: a knowledge test and short case studies in a first study, and a complex, dynamically evolving case study in the second study. In our cross-sectional studies, psychology students, trainees in a certified postgraduate psychotherapist curriculum, and behavior therapists with more than ten years of experience were tested (100 in total: 20 each of novice, intermediate, and advanced university students, postgraduate trainees, and therapists). Clinical knowledge and competences increased up to the level of trainees but unexpectedly decreased at the level of experienced therapists. We discuss the results against the background of expertise research and the training of clinical psychologists (in Germany). Essential factors for continuing education of psychotherapists are proposed.
