Nutritional status of children with neurodevelopmental disorders: a cross-sectional study at a tertiary-level hospital in northern Bangladesh.

BACKGROUND: Malnutrition in children with neurodevelopmental disorders (NDDs) is a significant global public health issue. Nutritional assessment combined with management or advice are essential to produce optimal outcomes. OBJECTIVES: The objective of this study was to assess nutritional status and the sociodemographic profile of children with neurodevelopmental disorders in Bangladesh. METHODS: A cross-sectional study was conducted from December to April 2020 among the population of children with NDDs who presented to the pediatric department of the TMSS Medical College and Rafatullah Community Hospital in Bogura during this period. Socio-demographic data along with anthropometric measurements of the children were taken. Assessment of nutritional status were made using metrics such as z-scores for weight-for-age (WAZ), height-for-age (HAZ), and body mass index-for-age (BAZ). Descriptive statistics (number and percentage) and analytical statistics (chi-square and logistic regression) were included. RESULTS: 58.6% of children displayed malnutrition, with 47.8% showing undernutrition (WHZ / BAZ - 1 SD-≤-3 SD), and 10.8% overnutrition (BAZ > 2SD). Significant negative associations were found between malnutrition and parental education level, urban residency, and monthly family income. Children diagnosed with cerebral palsy exhibited twice the likelihood to be malnourished (AOR 2.39, 95% CI 0.83-6.87). Furthermore, residing in rural regions was associated with an increased risk of experiencing malnutrition, as indicated by an adjusted odds ratio of 1.60 (95% CI 0.12-3.09). CONCLUSIONS: While the results are cross-sectional, over half of children with NDDs were found to be malnourished, suggesting that children with NDD in Bangladesh are vulnerable to developing any form of malnutrition. Therefore, regular assessments and timely nutritional support may improve their situation.

Health professionals' experiences of whistleblowing in maternal and newborn healthcare settings: A scoping review and thematic analysis.

PROBLEM: Whistleblowing, which involves raising concerns about wrongdoing, carries risks yet can be crucial to ensuring the safety of health service users in maternal and newborn healthcare settings. Understanding of the experiences of health care professionals that enact whistleblowing in this context is currently limited. BACKGROUND: Notable inquiries involving maternity services such as those reported upon by Ockenden and Kirkup and the Lucy Letby case in the United Kingdom have shone an international spotlight on whistleblowing failures. AIM: To identify and synthesise available literature addressing the experiences of healthcare professionals enacting whistleblowing in maternal and newborn care settings. METHODS: This scoping review followed Arksey and O'Malley's framework. Five academic databases were systematically searched for documents published between January 2013 and October 2023 with additional searches of Google Scholar and related reference lists. FINDINGS: Whilst 35 papers from international sources were identified, the majority originated from the United Kingdom, where recent high-profile incidents have occurred. Thematic analysis identified three main themes: 'Structural Power', 'Perfectionism' and 'Bravery, Hope and Disappointment', each with sub-themes. DISCUSSION: Whistleblowing is frequently an altruistic act in a hierarchical system. It exposes poor practices and disrupts power dynamics, especially in challenging workplace cultures. Open disclosure, however, requires psychological safety. Obstacles persist, emphasising the need for a culture of trust and transparency led by individuals who embody the desired values. CONCLUSION: Primary research on whistleblowing in maternal and newborn healthcare settings is limited. This study sheds light on power dynamics and factors that affect whistleblowing.

Social media influencers' impact during pregnancy and parenting: A qualitative descriptive study.

Pregnant people and parents engage with social media networking sites seeking support and information that is shared in a relatable way. Engaging with social media influencers (SMIs) and their followers, however, may have both affirming and harmful effects. SMIs can facilitate information-sharing, discussion, and supportive behaviors, but engaging with SMIs can lead to negative experiences and exposure to misinformation. To date, little is known about the impacts of following influencers during pregnancy and early parenthood. The aim of this study was to explore how engaging with SMIs impacts pregnant people and parents of children aged 5 or under in Australia. A qualitative descriptive approach was taken. Qualitative data from 85 anonymously completed online written surveys were thematically analyzed using Braun & Clarke's six-step process. Five overarching themes and two subthemes were identified. The first theme, "Comparisons of self," held two subthemes: "Unfavorable comparisons of self to SMIs" and "Favorable comparisons of self to SMIs." Additional themes were "A virtual community of inspiration and togetherness," "Sharing of information, opinions & experiences," "Gatekeeping self-efficacy," and "Credibility." The findings of the study indicated that discordance between influencer-mediated expectations of parenthood and a person's actual experience may affect well-being and perceptions of parental self-efficacy. Information sought from influencers may substitute for face-to-face education by clinicians. Health professionals who are also influencers may possess the ability to provide evidence-based information. This content, however, is not without risk for bias or incompleteness.

Village doctors: a national telephone survey of Bangladesh's lay medical practitioners.

BACKGROUND: Bangladesh outperforms its Least Developed Country (LDC) status on a range of health measures including life expectancy. Its frontline medical practitioners, however, are not formally trained medical professionals, but instead lightly-trained 'village doctors' able to prescribe modern pharmaceuticals. This current study represents the most complete national survey of these practitioners and their informal 'clinics'. METHODS: The study is based on a national Computer Assisted Telephone Interviewing (CATI) of 1,000 informal practitioners. Participants were sampled from all eight divisions and all 64 districts of Bangladesh, including 682 participants chosen from the purposively recruited Refresher Training program conducted by the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B), supplemented with 318 additional participants recruited through snowball sampling. PRIMARY AND SECONDARY OUTCOME MEASURES: In addition to demographics, village doctors were asked about the characteristics of their 'clinics' including their equipment, their training, income and referral practices. RESULTS: Three quarters of the wholly male sample had not completed an undergraduate program, and none of the sample had received any bachelor-level university training in medicine. Medical training was confined to a range of short-course offerings. Village doctor 'clinics' are highly dependent on the sale of pharmaceuticals, with few charging a consultation fee. Income was not related to degree of short-course uptake but was related positively to degree of formal education. Finally, practitioners showed a strong tendency to refer patients to the professional medical care system. CONCLUSIONS: Bangladesh's village doctor sector provides an important pathway to professional, trained medical care, and provides some level of care to those who cannot afford or otherwise access the nation's established healthcare system. However, the degree to which relatively untrained paramedical practitioners are prescribing conventional medicines has concerning health implications.

Psychological risks experienced by interpreters in the domestic violence cases: a systematic review.

Interpreters occupy a complex position in police interviews involving domestic violence cases-neutral but necessary parties to traumatic content. The following systematic review explores the relatively sparse scholarly literature on interpreters' psychological responses to being a party to domestic violence interviews in a policing context. This article aims to explore themes of relevant studies targeting interpreters' mental health in such cases, with nine articles emerging from a comprehensive search of eight databases supplemented with a Google Scholar search. Various themes involving interpreters emerged from the ensuing analysis, including intrinsic difficulties, misguided expectations, role requirements, psychological impacts, posttraumatic growth, coping strategies, and recommendations for future research and practice, with findings holding implications for interpreting in other traumatic domains.

Pregnancy, spousal connectedness, and young married women's mental health: an analysis of the Bangladesh adolescent health and wellbeing survey.

Mental health disorders are responsible for 125.3 million disability-adjusted life years (DALYs) lost globally, with depression in adolescents rising faster than in adults. In total, more than 90% of the 1.2 billion adolescents in the world live in low- and middle-income countries (LMICs). Despite the rise in teenage marriage and pregnancy in LMICs, there is a paucity of research on the role of pregnancy as a risk factor for adolescent mental health, and the role of spousal connectedness as a potential protective factor. This study aims to address this gap. A total of 2408 currently married adolescent (aged 15-19 years) women from the Bangladesh Adolescent Health and Wellbeing Survey 2019-2020 were analysed. Multivariable models were used to assess the factors associated with depression symptoms and major depressive disorder (MDD). The prevalence of moderate/severe depressive symptoms or MDD among adolescents was 14.6%, well ahead of south Asian levels. The odds of having moderate/severe depressive symptoms (adjusted odds ratio [AOR]=1.94, 95% confidence interval [CI] 1.37-2.76) or MDD (AOR=1.63, 95%CI 1.18-2.25) were higher in pregnant adolescent women than in non-pregnant adolescent women. A closer relationship with one's husband reduced the risk of developing moderate/severe depressive symptoms (AOR=0.90, 95% CI 0.84-0.96) or MDD (AOR=0.91, 95% CI 0.86-0.97). Pregnancy and connectedness had no statistically significant interaction effect on depression. There is an urgent need for affordable and scalable interventions to reduce the risk of mental health morbidity in pregnant adolescent women especially in low- and middle-income countries.

The impact of social media influencers on pregnancy, birth, and early parenting experiences: A systematic review.

BACKGROUND: Pregnant and new parents are increasingly engaging with social media. The impacts of engaging with social media 'influencers' and 'bloggers' during a time of heightened vulnerability to influence, in particular, merits exploration. AIM: To systematically review the literature to identify what is known about how following social media 'influencers' and 'bloggers' impacts pregnant and new parents' experiences and decision-making. METHODS: A search of CINAHL, World of Science, Medline, EMBASE and Google Scholar databases was undertaken in January 2023 to identify the literature focusing on the impacts of engaging with influencers or bloggers as pregnant or new parents. The reference lists of the included papers were hand-searched. Data were extracted from each paper, tabulated, and thematically analysed. The review was reported using the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. FINDINGS: Seventeen papers met the inclusion criteria and were included in the final synthesis. Thematic analysis revealed four overarching themes, which were 'sharing information', 'support', 'identity', and 'monetisation'. DISCUSSION: Social media influencers provide a network of peers amongst whom discussions, supportive behaviours, and information sharing take place. However, concern arises around the potential for combative interactions, the risk for transmission of misinformation, and the potential impacts of following influencers who are also qualified health professionals. CONCLUSION: Existing research suggests that engaging with social media influencers can be both beneficial and harmful for pregnant and new parents. At the current time, it is unclear how exposure to the benefits or harm impacts personal experiences and decision-making.

Saliva cortisol levels and physiological parameter fluctuations in mild traumatic brain injury patients compared to controls.

BACKGROUND: Evidence suggests that fluctuations of cortisol and physiological parameters can emerge during the course of mild Traumatic Brain Injury (mTBI). OBJECTIVE: To investigate fluctuations of cortisol and physiological parametersduring the acute phase of mTBI in hospitalized patients. METHODS: 30 participants (19 patients with mTBI and 11 controls) were examined for saliva cortisol dynamics, heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP) and body temperature (BT) fluctuations for four consecutive days. Also, the participants completed the Athens Insomnia Scale and Epworth Sleepiness Scales, in order to check for sleep problems. RESULTS: Patients showed elevated levels of cortisol relative to controls (peak at 8 am and lowest levels at 12 am), as well as for most physiological parameters. MAP was significantly higher for patients throughout the measurement period, and BT was elevated for patients relative to controls at almost all measurements of the first and second day. Mean HR tended to track at non-significantly higher levels for the mTBI group. Patients' sleepiness and insomnia values (ESS and AIS) were initially significantly higher relative to controls but the difference dissipated by day 4. CONCLUSION: The increase in absolute values of cortisol and physiological parameters measurements, indicates that in the acute phase of mTBI, a stressful process is activated which may affect sleep quality as well.Supplemental data for this article is available online at at doi: 10.1080/00207454.2021.1951264.

Workplace violence in the Australian and New Zealand midwifery workforce: A scoping review.

AIM: The aim of the study is to identify and map what is known about workplace violence involving midwives in Australia and New Zealand. BACKGROUND: Research from the United Kingdom demonstrates that workplace violence within maternity services is a pervasive issue with significant and wide-ranging clinical, individual and organisational consequences. To date, little is known about this issue within Australian and New Zealand maternity services. EVALUATION: A scoping review, guided by Arksey and O'Malley's framework, was conducted. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Just one identified study aimed to explore midwives' experiences of workplace violence. A further nine arrived at related results or themes. KEY ISSUES: Workplace violence is present in a variety of forms across maternity services in Australia and New Zealand. Its prevalence is, however, yet to be understood. Workplace violence causes physical and mental health issues for midwives, premature workforce attrition, and jeopardizes the quality and safety of maternity care. CONCLUSIONS: Workplace violence has been acknowledged as one of the key contributing factors towards premature attrition from the midwifery profession, with new graduate midwives most likely to leave. With the midwifery workforce ageing and evidence of serious clinical implications emerging, workplace violence needs urgent research and organisational attention. IMPLICATIONS FOR NURSING MANAGEMENT: Workplace violence is a key contributing factor towards recruitment and retention challenges for managers. To help tackle this, managers have a key role to play in identifying and effectively addressing workplace violence by acting as positive role models, taking a zero-tolerance approach and fostering collegial relationships. Managers, holding key clinical leadership positions, are pivotal to ensuring all complaints raised are handled with transparency and consistency regardless of one's position within the clinical hierarchy and organisational structure.

A multilevel assessment of the influence of education on women's uptake of institutional delivery services during childbirth in Bangladesh.

OBJECTIVES: Despite a significant decline over time, maternal mortality remains high in Bangladesh. Institutional delivery during childbirth is crucial to reducing maternal mortality, but uptake of institutional delivery services (IDS) remains suboptimal in Bangladesh. Though women's education plays a crucial role in the use of IDS, the educational status of the household head and area-level literacy rate also appear to act as predictors of IDS uptake. This study aims to assess the effect of the educational status of women and household heads as well as district-level adult literacy rates on the use of IDS during childbirth among women in Bangladesh. DESIGN: This study analyzed nationally representative cross-sectional survey data from the 2019 Bangladesh Multiple Indicator Cluster Survey. SETTING: Bangladesh. PARTICIPANTS: 9,207 currently married women aged 15-49 years who had at least one live birth in the two years preceding the survey were included in the study. The outcome measure was women's use of IDS during their last childbirth. A multilevel logistic regression model was used to explore the association between education status of women and household heads, and district (i.e., area unit) adult literacy rates and uptake of IDS among women in Bangladesh by controlling for other sociodemographic covariates and clustering. RESULTS: About 53% of women used IDS during childbirth. Adjusting for other factors and clustering, women with higher educational status, those living in households with higher-educated heads, and those in districts with greater adult literacy rates are more likely to use IDS, after controlling for key sociodemographic variables including wealth. CONCLUSIONS: Uptake of IDS in Bangladesh remains low, with education playing an important independent role in determining rates. The findings of the study provide empirical evidence for policymakers to design multi-modal educational programs targeted not only at literate women but also at household head (especially male) and communities where literacy (and equally importantly health literacy) may be variable or absent.

Survival of rural telehealth services post-pandemic in Australia: A call to retain the gains in the 'new normal'.

AIM: COVID-19 rapidly transformed how Australians access health care services. This paper considers how the inability for urban patients to access in-person care expediated the introduction of virtual solutions in health service delivery thus creating a new access paradigm for rural and remote Australians. CONTEXT: 'Physical distancing' is a phrase synonymous with public health responses to COVID-19 in Australia, but distance is a decades-long problem for rural health access. Counterintuitively, the pandemic and associated restrictions on mobility have reduced in real terms the distance from, and therefore the time taken to access, critical public services. 'Lockdowns' have unlocked health access for rural and remote Australians in ways that had been rejected prior to 2020. The pandemic has disrupted traditional delivery models and allowed the piloting of novel solutions, at the same time as stress-testing current delivery systems. In the process, it has laid bare a myopia we term 'urban paternalism' in understanding and delivering rural health. APPROACH: This commentary outlines how the COVID-19 operating environment has challenged traditional urban-dominated policy thinking about virtual health care delivery and how greater availability of telehealth appointments goes some way to reducing the health access gap for rural and remote Australians. CONCLUSION: Australian Commonwealth Government policy changes to expand the Medical Benefit Scheme (MBS) to include telephone or online health consultations are a positive initiative towards supporting Australians through the ongoing public health crisis and have also created access parity for some rural and remote patients. Although initially announced as a temporary COVID-19 measure in March 2020, telehealth has now become a permanent feature of the Medicare landscape. This significant public health reform has paved the way for a more flexible and inclusive universal health care system but, more importantly, taken much needed steps towards improving access to primary health care for patients in rural and remote areas. Now the question is: Can the health care system integrate this virtual model of delivery into 'business as usual' to ensure the long-term sustainability of telehealth services to rural and remote Australia?

Under the regulatory radar: Unregulated rural healthcare in Bangladesh and Australia.

This study examines health regulation under conditions of geographical constraint in two strikingly different settings, one on a remote island in Bangladesh and the other in an impoverished rural region in Australia. Both suffer from an absence of medically qualified professionals, which means that in the resultant vacuum, patients access alternative healthcare. The concept of regulation (or lack of regulation) is explored in terms of unconventional new responses to rural health deficits. The two cases show unexpected commonality, with policymakers facing shared challenges beyond physical remoteness. The difference in the degree of enforcement of regulation offers the greatest point of difference. This comparative study revealed a weak health regulatory system in the remote Bangladesh area of Bhola Island where 'alternatives' to formal clinical approaches have become the default choice. Brazen stop-gap servicing is commonplace on Bhola Island, but in The Gemfields such practices only occur in the shadows or as a last resort. Each isolated location, one in a developing country and the other in a developed setting, exemplifies how geographical remoteness can present an opportunity for innovations in supply to emerge. Surprisingly, it is the developing world case that better leverages a regulatory void to respond to local healthcare needs.

The parents are watching: Midwifery students' perceptions of how workplace bullying impacts mothers and babies.

PROBLEM: Bullying in the midwifery profession has been documented and the problem is now known to extend to the poor treatment of midwifery students. In nursing, research has shown that bullying in the clinical workplace can adversely impact on quality of care. To date, no research has explored whether the bullying of midwifery students has secondary impacts on the experiences and care of mothers, babies, and their support persons. AIM: To examine how midwifery students, who self-identify as having been bullied, perceive the repercussions on women and their families. METHODS: This qualitative descriptive study explored 120 Australian and United Kingdom (UK) based midwifery students. Data were collected using an anonymous online qualitative survey and were thematically analysed. FINDINGS: The findings suggest that the bullying of midwifery students impacts women and their families in a number of ways. Midwifery students perceive that mothers and babies are frequently implicated either directly or indirectly in the enactment of bullying. This can impact their safety, fractures relationships, and impairs the women's confidence in the student and the profession. Students additionally reported that women and/or their support persons can feel compelled to step in to defend and protect the student. CONCLUSIONS: The bullying of midwifery students is perceived to place women at risk, in uncomfortable situations, damage rapport and undermines their confidence in students and the profession. This also impacts adversely on the student's ability to provide women centred care as they lose confidence in front of the woman and her family when they are bullied by registered midwives.

Social culture and the bullying of midwifery students whilst on clinical placement: A qualitative descriptive exploration.

The context within which midwifery students are professionally socialised is thought to impact upon the development of their sense of belongingness, their attitudes and values, and their commitment to the midwifery profession. Negative forms of socialisation are known to lead to undesirable outcomes including desensitisation about humanistic needs. This has potential to extend to an acceptance of workplace bullying and unfair treatment of others, including midwifery students whilst on clinical placement. This study aimed to explore how the social culture of the maternity setting influences midwifery students' experiences of being bullied whilst on clinical placement. One hundred and twenty midwifery students from Australia and the United Kingdom completed a qualitative online survey and the data was thematically analysed. One main overarching theme and four sub themes were identified. These were: 'the organisational culture of acceptance: "in front of"', 'brazen expression', 'group buy-in', 'suppression of dissent', and 'collateral damage'. Each of these factors enabled replication of the problem and led to perpetuation of the bullying cycle. This study illuminated that an entrenched culture of acceptance exists which impacts the students educational experience, the care received by mothers and babies, and the reputation of the midwifery profession.

Midwifery students' perceptions of the modifiable organisational factors that foster bullying behaviours whilst on clinical placement. A qualitative descriptive study.

PROBLEM: An increasing body of research suggests midwifery students experience bullying and harassment whilst on clinical placement. Little is known, however, about factors that foster bullying within this context and how they may be addressed. AIM: To explore and describe midwifery students' perceptions of what modifiable organisational factors foster bullying behaviours and to map the identified factors against the students' perceptions of a solution. METHODS: A qualitative descriptive design was used. A total of 120 midwifery students from the United Kingdom and Australia participated in this study. Participants completed an online qualitative survey and data was thematically analysed. FINDINGS: The midwifery students in this study perceive that several organisational factors exist that help foster bullying behaviours towards them whilst undertaking clinical placement. Three overarching themes were identified relating to ineffective midwifery mentorship, the high stress environment of the maternity unit, and challenges faced with transparency and whistleblowing. Students identified a range of potential structural responses to bullying. CONCLUSIONS: Recommendations are made that midwifery managers and academics acknowledge how students perceive several potentially modifiable organisational factors which either lead to or exacerbate the likelihood of them being the target of bullying whilst on clinical placement. Consideration should be given to solutions that from the student's perspective may help tackle bullying and subsequently lead to fewer students leaving midwifery education and further depleting the future workforce.

Midwifery students' experiences of bullying and workplace violence: A systematic review.

BACKGROUND: Workplace violence directed at registered midwives in the maternity setting has been a recognised issue since the early 1990s. More recently it has become evident that midwifery students are also victims of bullying and harassment whilst on clinical placement. Due to the short and long-term impacts this has on students, it is likely to have a detrimental effect on the future and sustainability of the midwifery profession. As a basis for designing a response, it is important to understand what is currently known about this phenomenon. AIM: To systematically review the literature to identify what is known about workplace violence and bullying experienced by midwifery students whilst on clinical placement. METHOD: Reporting of this review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search was undertaken of all primary research that focussed upon workplace violence and bullying involving midwifery students whilst on clinical placement, published between January 1990 and December 2019. Pre-defined terms were used to search the following five databases: CINAHL, Web of Science, MEDLINE, Embase, supplemented with Google Scholar. Additional manual searches of reference lists were conducted. An assessment of the quality of each eligible study was then undertaken using an appropriate mixed methods appraisal tool (MMAT). Extracted data were then synthesised using thematic synthesis. FINDINGS: Nine articles met the criteria for inclusion in the review. Studies were primarily qualitative, with some reporting descriptive statistics that do not enable key issues such as prevalence to be reliably addressed. The synthesis identified four main themes that related to workplace violence and bullying of midwifery students whilst on clinical placement. Results were clustered around the role of power in bullying, prevalence and impacts, the culture of compliance, and the victim's response. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: A broader understanding of the nature of workplace violence and bullying and how it manifests itself is beginning to emerge, but more and higher quality research is required to establish an empirical base on which to design interventions. Studies suggest that bullying is common and has significant impacts at both a personal and professional level.  This strongly reinforces a need for greater policy and organisational responses to bullying in the clinical education context, in order to break the bullying cycle and ensure the midwives of the future remain in the profession and sustain the workforce.

Healthcare Capacity, Health Expenditure, and Civil Society as Predictors of COVID-19 Case Fatalities: A Global Analysis.

Background: The rapid growth in cases of COVID-19 has challenged national healthcare capacity, testing systems at an advanced ICU, and public health infrastructure level. This global study evaluates the association between multi-factorial healthcare capacity and case fatality of COVID-19 patients by adjusting for demographic, health expenditure, population density, and prior burden of non-communicable disease. It also explores the impact of government relationships with civil society as a predictor of infection and mortality rates. Methods: Data were extracted from the Johns Hopkins University database, World Bank records and the National Civic Space Ratings 2020 database. This study used data from 86 countries which had at least 1,000 confirmed cases on 30th April 2020. Negative binomial regression model was used to assess the association between case fatality (a ratio of total number of confirmed deaths to total number of confirmed cases) and healthcare capacity index adjusting for other covariates. Findings: Regression analysis shows that greater healthcare capacity was related to lesser case-fatality [incidence rate ratio (IRR) 0.5811; 95% confidence interval (CI) 0.4727-0.7184; p < 0.001] with every additional unit increase in the healthcare capacity index associated with a 42% decrease in the case fatality. Health expenditure and civil society variables did not reach statistical significance but were positively associated with case fatalities. Interpretation: Based on preliminary data, this research suggests that building effective multidimensional healthcare capacity is the most promising means to mitigate future case fatalities. The data also suggests that government's ability to implement public health measures to a degree determines mortality outcomes.

The 'lifecycle' of human beings: a call to explore vector-borne diseases from an ecosystem perspective.

BACKGROUND: Dengue virus, an Aedes mosquito-borne flavivirus, is associated with close to 400 million reported infections per annum worldwide. Reduction of dengue virus transmission depends entirely on limiting Aedes breeding or preventing adult female contact with humans. Currently, the World Health Organization promotes the strategic approach of integrated vector management in order to optimise resources for mosquito control. MAIN TEXT: Neglected tropical disease researchers focus on geographical zones where the incidence of clinical cases, and prevalence of vectors, are high. In combatting those infectious diseases such as dengue that affect mainly low-income populations in developing regions, a mosquito-centric approach is frequently adopted. This prioritises environmental factors that facilitate or impede the lifecycle progression of the vector. Climatic variables (such as rainfall and wind speed) that impact the vector's lifecycle either causally or by happenstance also affect the human host's 'lifecycle', but in very different ways. The socioeconomic impacts of the same variables that influence vector control impact host vulnerability but at different points in the human lifecycle to those of the vector. Here, we argue that the vulnerability of the vector and that of the host interact in complex and unpredictable ways that are characteristic of (complex and intransigent) 'wicked problems'. Moreover, they are treated by public health programs in ways that may ignore this complexity. This opinion draws on recent evidence showing that the best climate predictors of the scale of dengue outbreaks in Bangladesh cannot be explained through a simple vector-to-host causal model. CONCLUSIONS: In mapping causal pathways for vector-borne diseases this article makes a case to elevate the lifecycle of the human host to a level closer in equivalence to that of the vector. Here, we suggest value may be gained from transferring Rittel and Webber's concept of a wicked (social) problem to dengue, malaria and other mosquito-transmitted public health concerns. This would take a 'problem definition' rather than a 'solution-finding' approach, particularly when considering problems in which climate impacts simultaneously on human and vector vulnerability.
