Vulnerabilities and reparative strategies during pregnancy, childbirth, and the postpartum period: moving from rhetoric to action

Maternal outcomes throughout pregnancy, childbirth, and the postnatal period are influenced by interlinked and interdependent vulnerabilities. A comprehensive understanding of how various threats and barriers affect maternal and perinatal health is critical to plan, evaluate and improve maternal health programmes. This paper builds on the introductory paper of the Series on the determinants of maternal health by assessing vulnerabilities during pregnancy, childbirth, and the postnatal period. We synthesise and present the concept of vulnerability in pregnancy and childbirth, and map vulnerability attributes and their dynamic influence on maternal outcomes in early and late pregnancy and during childbirth and the postnatal period, with a particular focus on low-income and middle-income countries (LMICs). We summarise existing literature and present the evidence on the effects of various reparative strategies to improve pregnancy and childbirth outcomes. Lastly, we discuss the implications of the identified vulnerability attributes and reparative strategies for the efforts of policymakers, healthcare professionals, and researchers working towards improving outcomes for women and birthing people in LMICs.

Improving emotional and psychosexual well-being screening in women living with polycystic ovary syndrome: experiences from the United Kingdom and India

With increasing evidence of emotional well-being disorders associated with polycystic ovary syndrome (PCOS), effective screening processes are of utmost importance. We studied the impact of using questionnaires to screen for emotional and psychosexual well-being across different models of care for PCOS. We analysed the data from the surveys to assess the difference in the prevalence of emotional and psychosexual ill-being across ethnicity and region. In this prospective cohort study, we invited all women attending consultations for PCOS in Birmingham, UK, and Bengaluru and Navi Mumbai, India. Those who consented to participate in the study were invited to complete a pre-clinic survey about socio-demographic data, Hospital Anxiety and Depression Scale (HADS), Body Image Concern Inventory (BICI), Beliefs about Obese Person scale (BAOP), and Female Sexual Function Index score (FSFI) and a post-clinic survey on clinic experience, lifestyle advice, and specialist referral. A total of 115 women were included in this study. The rate of questionnaire completion was 98.3% (113/115), 97.4% (112/115), 93.04% (107/115), and 84.3% (97/115) for HADS, BICI, BAOP, and FSFI, respectively. In the post-clinic survey, 28.8% reported they were screened for anxiety, 27.1% for depression, and 45.8% for body image concerns. The prevalence of anxiety, depression, and body dysmorphic disorder through pre-clinic survey was 56.5% (50.0% UK vs 59.5% India, P = 0.483), 16.5% (13.9% UK vs 17.7% India, P = 0.529), and 29.6% (36.1% UK vs 26.6% India, P = 0.208), respectively. Surveys with validated questionnaires can improve screening for emotional and psychosexual well-being associated with PCOS which may be missed by ad hoc screening during consultations.

Bacterial MgSe complex nanoparticle synthesis and electrical characterization of fabricated Ag/MgSe/p-Si hetero-structure under dark and illumination

The Pseudomonas aeruginosa OG1 strain was used in the bacterial synthesis of MgSe compound nanoparticles. The obtained samples were subsequently shaped into nanocrystalline MgSe films, and their optical, structural, morphological, and electrical properties were assessed on glass and p-Si substrates. Structural and morphological characterizations showed that the fabricated thin film samples have a polycrystalline structure with high quality and uniform grain sizes. The MgSe films produced on glass substrates exhibit a direct spectral band gap of 2.53 eV, according to optical measurements. The Ag/MgSe/p-Si layered diode structure was fabricated using the produced MgSe nanoparticles and then characterized by electrical properties. Electrical measurements were carried out under these two conditions to assess the effects of dark and illumination conditions on the band dynamics of the heterostructure devices. Under illumination, the barrier height decreased while the interface density states distribution increased. These measurements showed that using bacterial-assisted grown MgSe nanocrystalline films, the developed Ag/MgSe/p-Si device structure exhibited a remarkable photoresponse and stable rectifying property. Green synthesis methods for the production of these nanocrystalline materials have the potential to offer low-cost alternatives for photosensitive applications.

Measurements of Surgical Volume in Low- and Middle-Income Countries, a Systematic Review

Background

Surgical volume is a surgical indicator that was described in the Lancet Commission on Global Surgery (LCoGS) and the World Bank World Development Indicators as an important metric for tracking the delivery of surgical care.

Objectives

We aimed to characterize the reports on surgical volume (SV) in the existing literature by using a systematic review to assess studies that examine surgical procedures as a ratio of a population (procedures/100,000 population).

Methods

The PRISMA guideline was employed in the systematic review of articles that addressed the measurement of SV in low- and middle-income countries (LMICs), with the primary outcome of surgical procedures/100,000 population.

Findings

The search result consisted of 6,657 preliminary studies. Following the title and abstract screening, 6,464 articles were excluded, and the remaining 193 were included in the full text review. From the full text review of the 193, only 26 of these articles defined SV as the ratio of number of procedures per population of the catchment/geographical area. The reported SV was a mean of 765, with an SD of 1260 operations per 100,000. The median SV was 180 (min = 0.900, max = 4470).

Conclusion

Our findings support the LCoGS assessment of the gap in surgical care. The target for SV is 5000 per 100,000 population, compared to the average of 765 per 100,000 population as found in this review. The challenges for assessing surgical volume gaps are vast, including the nature of written records, which limits SV reports to an absolute number of procedures per year without a reference to the catchment population. For the purpose of tracking SV, we recommend using proxies that account for the capacity of facilities to deliver care regardless of the catchment population.

Body image concerns in women with polycystic ovary syndrome: a systematic review and meta-analysis

OBJECTIVE

To assess differences in body image concerns among women with and without polycystic ovary syndrome (PCOS).

DESIGN

This is a systematic review and meta-analysis.

METHODS

Electronic databases (MEDLINE, EMBASE, APA PsychInfo, PUBMED, Web-of-Science Core Collection, and Cochrane Controlled Register of Trials [CENTRAL]) were searched from inception through July 2022. Outcome measures included validated questionnaires reporting on body image concerns. Methodological quality was assessed by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system, and included studies were assessed for risk of bias. Meta-analyses were performed using the inverse variance method based on random or fixed effects models (Review Manager, Version 5).

RESULTS

A total of 918 women with PCOS and 865 women without PCOS from 9 studies were included. Meta-analysis of 3 studies using Multidimensional Body-Self Relations Questionnaire Appearance Scale (MBSRQ-AS) showed those with PCOS reported higher dissatisfaction with appearance evaluation and appearance orientation compared to those without PCOS (mean difference [MD] = -0.78, I2 = 0%, P < .00001, and MD = 0.22, I2 = 54%, P = .004, respectively). Meta-analysis of 2 studies showed higher dissatisfaction with overweight preoccupation, lower body area satisfaction, and body weight classification on MBSRQ-AS subscales in those with PCOS compared to those without PCOS (all P < .001). Meta-analysis of 2 studies using the Body Esteem Scale for Adolescents and Adults (BESAA) showed significantly lower scores for the weight subscale in those with PCOS compared to those without PCOS (P = .03).

CONCLUSIONS

Those with PCOS experience more significant body image concerns, emphasising the importance of awareness in the clinical care of PCOS. Considering the limited evidence, further studies are warranted to identify drivers and mitigating factors.

Emotional and psychosexual well-being is influenced by ethnicity and birthplace in women and individuals with polycystic ovary syndrome in the UK and India

OBJECTIVE

To assess the association of ethnicity and birthplace on emotional and psychosexual well-being in women with polycystic ovary syndrome (PCOS).

DESIGN

Cross-sectional study.

SETTING

Community recruitment via social media campaigns.

POPULATION

Women with PCOS completing an online questionnaire in September-October 2020 (UK) and May-June 2021 (India).

METHODS

The survey has five components, with a baseline information and sociodemographic section followed by four validated questionnaires: Hospital Anxiety and Depression Scale (HADS); Body Image Concern Inventory (BICI); Beliefs About Obese Persons Scale (BAOP); and Female Sexual Function Index (FSFI).

MAIN OUTCOME MEASURES

We used adjusted linear and logistic regression models, adjusting for age, education, marital status and parity, to evaluate the impact of ethnicity and birthplace on questionnaire scores and outcomes (anxiety and/or depression, HADS ≥ 11; body dysmorphic disorder (BDD), BICI ≥ 72).

RESULTS

A total of 1008 women with PCOS were included. Women of non-white ethnicity (613/1008) reported higher rates of depression (OR 1.96, 95% CI 1.41-2.73) and lower BDD (OR 0.57, 95% CI 0.41-0.79) than white women (395/1008). Women born in India (453/1008) had higher anxiety (OR 1.57, 95% CI 1.00-2.46) and depression (OR 2.20, 95% CI 1.52-3.18) but lower BDD rates (OR 0.42, 95% CI 0.29-0.61) than women born in the UK (437/1008). All sexual domains, excluding desire, scored lower for non-white women and women born in India.

CONCLUSIONS

Non-white women and women born in India reported higher emotional and sexual dysfunction, whereas white women and women born in the UK reported higher body image concerns and weight stigma. Ethnicity and birthplace need to be considered for tailored, multidisciplinary care.

A mechanical task for measuring sign- and goal-tracking in humans: A proof-of-concept study

Cue-based associative learning (i.e., Pavlovian conditioning) is a foundational component of behavior in almost all forms of animal life and may provide insight into individual differences in addiction liability. Cues can take on incentive-motivational properties (i.e., incentive salience) through Pavlovian learning. Extensive testing with non-human animals (primarily rats) has demonstrated significant variation among individuals in the behaviors this type of learning evokes. So-named "sign-trackers" and "goal-trackers" have been examined in many studies of non-human animals, but this work in humans is still a nascent area of research. In the present proof-of-concept study, we used a Pavlovian conditioned approach task to investigate human sign- and goal-tracking in emerging adults. Conditioned behaviors that developed over the course of the task were directed toward the reward-cue and toward the reward location. Participants' eye-gaze and behavior during the task were submitted to a latent profile analysis, which revealed three groups defined as sign-trackers (n = 10), goal-trackers (n = 4), and intermediate responders (n = 36). Impulsivity was a significant predictor of the sign-tracking group relative to the goal-tracking group. The present study provides preliminary evidence that a simple procedure can produce learned Pavlovian conditioned approach behavior in humans. Though further investigation is required, findings provide a promising step toward the long-term goal of translating important insights gleaned from basic research into treatment strategies that can be applied to clinical populations.

Peer mentorship to build research capacity among members of the International Student Surgical Network (InciSioN): a proof of concept study

BACKGROUND

International Student Surgical Network (InciSioN) is the largest student and trainee global surgery interest group worldwide and its members have contributed significantly to global surgery research. The InciSioN Research Capacity-Building (IReCaB) program aimed to enhance the research skills and confidence of participants via a peer mentorship model.

METHODS

After an open call to members of InciSioN to enroll, participants' knowledge of research methods and the process was evaluated through a test to assign mentor and mentee roles, with mentors being those who scored ≥ 20/25. Mentors then delivered a series of four webinars to help disseminate research methodology to mentees. Finally, mentees were tested on their knowledge of research and their satisfaction with the program was also evaluated.

RESULTS

Fifty-two participants, mostly from LMICs (n = 23/52, 44.2%) were enrolled, and 36 completed the program. There was a significant improvement in the proportion of questions answered correctly on the post-program test (R = 0.755, p < 0.001). Post-IReCaB test scores were greater than pre-IReCaB scores (p < 0.001). The difference in confidence after the course was also significant (p < 0.001). IReCaB participants successfully designed, implemented, and published an international cross-sectional study.

CONCLUSION

This study showed improvements in participants' understanding of theoretical components of scientific research. We offer a model for research capacity building that can be implemented, modeled, and further refined by similar organizations with academic research goals.

Ethnicity-related stereotypes and their impacts on medical students: A critical narrative review of health professions education literature

BACKGROUND

Stereotypes are oversimplified beliefs about groups of people. Social psychology concepts and theories describing ethnicity-related stereotypes are well reported in non-medical educational settings. In contrast, the full impact of stereotyping on medical students, and the extent to which they were represented in health professions education (HPE) is less well-described. Using the lens of social psychological theory, this review aimed to describe ethnicity-related stereotypes about medical students portrayed in HPE literature and the impacts of those stereotypes.

METHODS

A critical narrative approach was undertaken. Social psychology concepts and theories were used as a framework through which to review the impacts of ethnicity-related stereotypes on medical students as described in HPE literature. A database search of Ovid MEDLINE, JSTOR, Project Muse, and PsychINFO was conducted to identify both theoretical and empirical articles relating to this topic in the HPE literature. Data was synthesised using thematic analysis, giving particular care to appraise the evidence from perspectives in social psychology.

FINDINGS

In HPE, the experiences and impact of stereotyping on learners from minority ethnic groups was explained by social psychology concepts such as stereotype threat, stereotype reactance, attributional ambiguity, self-fulfilling prophecy, stereotype boost, stereotype lift, and stereotype masking. Stereotype boost and stereotype lift were particularly described among students who identified as White, whereas stereotype threat was described more commonly among students from minority ethnics groups. The impact of stereotyping is not just on assessment, but may be across all teaching and learning activities at medical school.

INTERPRETATION

Social psychology concepts and theories can be used to describe the experience and impact of ethnicity-related stereotypes in HPE. Educators can better support learners from minority ethnic groups by self-reflecting over assumptions about individuals from minority ethnic groups, as well as minimise the impact of stereotyping and bias to create more inclusive learning environments.

Differentiating between Evidence/gap maps and scoping reviews in the evidence synthesis ecosystem

OBJECTIVE

Scoping reviews and evidence map methodologies are increasingly used by researchers. The objective of this article is to outline the main differences between both types of evidence synthesis to improve their conduct.

STUDY DESIGN AND SETTING

This article summarizes the key issues facing reviewers who conduct scoping reviews and evidence maps and those who use the results and may engage in consultations during their development.

RESULTS

Several differences exist between the methodologies, and these are in their protocol development, scope, inclusion criteria, data extraction, reporting, and use. Evidence maps are mainly driven by questions of effectiveness of a particular intervention and hence they use the PICOS format similar to systematic reviews of effectiveness. Scoping reviews mostly use the PCC format where they map a concept of interest relevant to a particular population in a specific setting and context. Data extraction is limited by only coding of studies and intervention characteristics in evidence maps. The results of the evidence maps can be used inform research priorities and research funding, whereas scoping reviews results may be used to inform policy development by clarifying key concepts and methods, and further research.

CONCLUSION

We recommend authors who are planning to undertake scoping reviews confirm that their research question can be appropriately answered using a scoping review methodology, however, for broader research questions without the need for an in-depth analysis of the information, we recommend authors to consider mapping reviews.

Systematic analysis of authorship demographics in global surgery

Background

Global surgery has recently gained prominence as an academic discipline within global health. Authorship inequity has been a consistent feature of global health publications, with over-representation of authors from high-income countries (HICs), and disenfranchisement of researchers from low-income and middle-income countries (LMICs). In this study, we investigated authorship demographics within recently published global surgery literature.

Methods

We performed a systematic analysis of author characteristics, including gender, seniority and institutional affiliation, for global surgery studies published between 2016 and 2020 and indexed in the PubMed database. We compared the distribution of author gender and seniority across studies related to different topics; between authors affiliated with HICs and LMICs; and across studies with different authorship networks.

Results

1240 articles were included for analysis. Most authors were male (60%), affiliated only with HICs (51%) and of high seniority (55% were fully qualified specialist or generalist clinicians, Principal Investigators, or in senior leadership or management roles). The proportion of male authors increased with increasing seniority for last and middle authors. Studies related to Obstetrics and Gynaecology had similar numbers of male and female authors, whereas there were more male authors in studies related to surgery (69% male) and Anaesthesia and Critical care (65% male). Compared with HIC authors, LMIC authors had a lower proportion of female authors at every seniority grade. This gender gap among LMIC middle authors was reduced in studies where all authors were affiliated only with LMICs.

Conclusion

Authorship disparities are evident within global surgery academia. Remedial actions to address the lack of authorship opportunities for LMIC authors and female authors are required.

Statistical optimization of amorphous iron phosphate: inorganic sol-gel synthesis-sodium potential insertion

Iron phosphate, Fe₂ (HPO₄)₃*4H₂O, is synthesized at ambient temperature, using the inorganic sol–gel method coupled to the microwave route. The experimental conditions for the gelling of Fe (III)-H₃PO₄ system are previously defined. Potentiometric Time Titration (PTT) and Potentiometric Mass Titration (PMT) investigate the acid–base surface chemistry of obtained phosphate. Variations of surface charge with the contact time, Q a function of T, are examined for time contact varying in the range 0–72 h. The mass suspensions used for this purpose are 0.75, 1.25 and 2.5 g L⁻¹. The point of zero charge (PZC) and isoelectric point (IEP) are defined using the derivative method examining the variations \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\frac{{{\text{dpH}}}}{{{\text{d}}t}} = f\left( {{\text{pH}}} \right)$$\end{document}dpHdt=fpH, at lower contact time. A shift is observed for PZC and IEP towards low values that are found to be 2.2 ± 0.2 and 1.8 ± 0.1, respectively. In acidic conditions, the surface charge behavior of synthesized phosphate is dominated by \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\overline{{ > {\text{POH}}}}$$\end{document}>POH¯ group which pK_a = 2.45 ± 0.15. Q against T titration method is performed for synthesized Fe₂ (HPO₄)₃*4H₂O in NaCl electrolytes. The maximal surface charge (Q) is achieved at the low solid suspension. Hence, for m = 0.75 g L⁻¹, Q value of 50 coulombs is carried at μ = 0.1 and pH around 12, while charge value around 22 coulombs is reached in the pH range: 3–10. The effect of activation time, Q and pH on sodium insertion in iron phosphate, were fully evaluated. To determine the optimal conditions of the studied process, mathematical models are used develop response surfaces in order to characterize the most significant sodium interactions according to the variation of the pH, Q, the contact time and the contents of the synthesized material.

Prevalence of Diarrheagenic Escherichia coli (DEC) and Salmonella spp. with zoonotic potential in urban rats in Salvador, Brazil

Studies evaluating the occurrence of enteropathogenic bacteria in urban rats (Rattus spp.) are scarce worldwide, specifically in the urban environments of tropical countries. This study aims to estimate the prevalence of diarrhoeagenic Escherichia coli (DEC) and Salmonella spp. with zoonotic potential in urban slum environments. We trapped rats between April and June 2018 in Salvador, Brazil. We collected rectal swabs from Rattus spp., and cultured for E. coli and Salmonella spp., and screened E. coli isolates by polymerase chain reaction to identify pathotypes. E. coli were found in 70% of Rattus norvegicus and were found in four Rattus rattus. DEC were isolated in 31.3% of the 67 brown rats (R. norvegicus). The pathotypes detected more frequently were shiga toxin E. coli in 11.9%, followed by atypical enteropathogenic E. coli in 10.4% and enteroinvasive E. coli in 4.5%. From the five black rats (R. rattus), two presented DEC. Salmonella enterica was found in only one (1.4%) of 67 R. norvegicus. Our findings indicate that both R. norvegicus and R. rattus are host of DEC and, at lower prevalence, S. enterica, highlighting the importance of rodents as potential sources of pathogenic agents for humans.

Adverse drug reactions in primary care: a scoping review

BACKGROUND

Medication-related adverse events, or adverse drug reactions (ADRs) are harmful events caused by medication. ADRs could have profound effects on the patients' quality of life, as well as creating an increased burden on the healthcare system. ADRs are one of the rising causes of morbidity and mortality internationally, and will continue to be a significant public health issue with the increased complexity in medication, to treat various diseases in an aging society. This scoping review aims to provide a detailed map of the most common adverse drug reactions experienced in primary healthcare setting, the drug classes that are most commonly associated with different levels/types of adverse drug reactions, causes of ADRs, their prevalence and consequences of experiencing ADRs.

METHODS

We systematically reviewed electronic databases Ovid MEDLINE, Embase, CINAHL Plus, Cochrane Central Register of Controlled Trials, PsycINFO and Scopus. In addition, the National Patient Safety Foundation Bibliography and the Agency for Health Care Research and Quality and Patient Safety Net Bibliography were searched. Studies published from 1990 onwards until December 7, 2018 were included as the incidence of reporting drug reactions were not prevalent before 1990. We only include studies published in English.

RESULTS

The final search yielded a total of 19 citations for inclusion published over a 15-year period that primarily focused on investigating the different types of adverse drug reactions in primary healthcare. The most causes of adverse events were related to drug related and allergies. Idiosyncratic adverse reactions were not very commonly reported. The most common adverse drug reactions reported in the studies included in this review were those that are associated with the central nervous system, gastrointestinal system and cardiovascular system. Several classes of medications were reported to be associated with adverse events.

CONCLUSION

This scoping review identified that the most causes of ADRs were drug related and due to allergies. Idiosyncratic adverse reactions were not very commonly reported in the literature. This is mainly because it is hard to predict and these reactions are not associated with drug doses or routes of administration. The most common ADRs reported in the studies included in this review were those that are associated with the central nervous system, gastrointestinal system and cardiovascular system. Several classes of medications were reported to be associated with ADRs.

Two-year patient-related outcome measures (PROM) of primary ventral and incisional hernia repair using a novel three-dimensional composite polyester monofilament mesh: the SymCHro registry study

Purpose

This study examined patient-related outcome measures (PROMs) after repair of ventral primary or incisional hernias using Symbotex™ composite mesh (SCM), a novel three-dimensional collagen-coated monofilament polyester textile.

Methods

Pre-operative, peri-operative, and post-operative data were obtained from the French “Club Hernie” registry with 12- and 24-month follow-up.

Results

One-hundred consecutive patients (mean age 62.0 ± 13.7; 51% female) underwent repair of 105 hernias: primary (39/105, 37.1%, defect area 5.2 ± 5.6 cm²) and incisional (66/105, 62.9%, 31.9 ± 38.7.8 cm²). The mean BMI was 29.7 (± 5.6 kg/m²). American Society of Anesthesiologists classifications were I 39.4%, II 37.4% and III 23.2%. 75% had risk factors for healing and/or dissection. Of 38 primary repairs, 37 were completed laparoscopically (combined approach n = 1), and of 62 incisional hernia repairs, 40 were completed laparoscopically, and 20 by open repair (combined approach n = 2). Laparoscopic was quicker than open repair (36.2 ± 23.5 min vs. 67.4 ± 25.8, p < 0001). Before surgery, 86.3% of hernias were reported to cause discomfort/pain or dysesthesia. At 24 months (93 of 100 patients), 91 (97.8%) reported no lump and 81 (87.1%) no pain or discomfort. Of 91 patients, 86 (94.5%) rated their repair “good” or “excellent.” There were nine non-serious, surgeon-detected adverse events (ileus, n = 3; seroma, n = 6) and one hernia recurrence (6–12 months).

Conclusions

Compared to baseline, open and laparoscopic surgery improved PROMs 24 months after primary and incisional hernia repair. Minimal complications and recurrence support the long-term efficacy of SCM.

Childhood central adiposity at ages 5 and 9 shows consistent relationship with that of the maternal grandmother but not other grandparents

BACKGROUND

The importance of a life course approach to childhood obesity has been emphasized; however, few studies can prospectively investigate relationships in three-generation families.

OBJECTIVE

To prospectively investigate the relationship between grandparental and grandchild waist circumference (WC) at ages 5 and 9 down maternal and paternal lines.

METHODS

At baseline in the Lifeways Cross-Generation Cohort, 1094 children were born to 1082 mothers; 585 were examined at age 5 and 298 at age 9. Of the total 589 children with measured WC, data were also available from 745 grandparents. Child WC was standardized for age and sex, and theory-based hierarchical linear regression was used.

RESULTS

Maternal grandmother (MGM) WC was predictive of grandchild WC at both time points. At age 5, grandchild's standardized birth weight (B = 0.266, p = 0.001), mother's means tested eligibility for free medical care (B = 1.029, p = 0.001) and grandchild seeing maternal grandparents daily (B = 0.312, p = 0.048) were significant alongside MGM WC (B = 0.015, p = 0.019). At age 9, only MGM WC (B = 0.022, p = 0.033) and mother's WC (B = 0.032, p = 0.005) were significant. Mediation analysis with mother's WC showed significant direct relationship of MGM and grandchild WC.

CONCLUSIONS

This prospective cross-generational cohort shows consistent patterns of association between MGM and grandchild WC, not seen in other grandparental lineages.

Diabetes microvascular complications-A clinical update

BACKGROUND

The purpose of this study is to summarise the empirical evidence addressing diabetes microvascular complications and management. The effects of diabetes mellitus include long-term damage, dysfunction and failure of various organs. Microvascular disease tends to occur predominantly in tissues where glucose uptake is independent of insulin activity because these tissues are exposed to glucose levels that correlate very closely with blood glucose levels. These metabolic injuries cause altered blood flow and changes in endothelial permeability, extravascular protein deposition and coagulation resulting in organ dysfunction which in turn lead to microvascular complications.

METHOD

A systematic search of the literature from 2000 to 2016 was conducted using four databases (Medline, Pubmed, Cochrane central and Google scholar) using search terms such as diabetic microvascular complications', pathogenesis, screening, risk factors, pharmacological and non-pharmacological interventions and management.

RESULTS

The current evidence supports a direct relationship between blood pressure (BP) and glycaemic control and progression of nephropathy and retinopathy. These are now considered as independent risk factors for microvascular disease progression. New fields of research addressing new drugs as potential therapeutic targets of the future will be presented.

CONCLUSION

The prevention of microvascular disease involves paying attention to aggravating risk factors and implementing screening programmes to improve early detection.

Total HDL cholesterol efflux capacity in healthy children - Associations with adiposity and dietary intakes of mother and child

BACKGROUND AND AIMS

High-density lipoprotein (HDL) cholesterol efflux capacity in adults may be a measure of the atheroprotective property of HDL. Little however, is known about HDL cholesterol efflux capacity in childhood. We aimed to investigate the relationship between HDL cholesterol efflux capacity and childhood anthropometrics in a longitudinal study.

METHODS AND RESULTS

Seventy-five children (mean age = 9.4 ± 0.4 years) were followed from birth until the age of 9 years. HDL cholesterol efflux capacity was determined at age 9 by incubating serum-derived HDL-supernatants with ³H-cholesterol labeled J774 macrophages and percentage efflux determined. Mothers provided dietary information by completing food frequency questionnaires in early pregnancy and then 5 years later on behalf of themselves and their children. Pearson's correlations and multiple regression analyses were conducted to confirm independent associations with HDL efflux. There was a negative correlation between HDL cholesterol efflux capacity and waist circumference at age 5 (r = -0.3, p = 0.01) and age 9 (r = -0.24, p = 0.04) and BMI at age 5 (r = -0.45, p = 0.01) and age 9 (r = -0.19, p = 0.1). Multiple regression analysis showed that BMI at age 5 remained significantly associated with reduced HDL cholesterol efflux capacity (r = -0.45, p < 0.001). HDL-C was negatively correlated with energy-adjusted fat intake (r = -0.24, p = 0.04) and positively correlated with energy-adjusted protein (r = 0.24, p = 0.04) and starch (r = 0.29, p = 0.01) intakes during pregnancy. HDL-C was not significantly correlated with children dietary intake at age 5. There were no significant correlations between maternal or children dietary intake and HDL cholesterol efflux capacity.

CONCLUSIONS

This novel analysis shows that efflux capacity is negatively associated with adiposity in early childhood independent of HDL-C.

Evaluation of pharmacy students' rural placement program: preparation for interprofessional practice

OBJECTIVE

To date, there are few data on pharmacy-specific placement programs and their impact on students' work after graduation. The present study evaluated an innovative rural pharmacy placement program targeted at influencing students to work and live in rural areas after graduation. A secondary aim of the study was to explore the students' intentions to come back and practice in rural areas as a result of their involvement in the rural pharmacy program.

METHODS

A questionnaire was distributed, by hand, to a total of 58 third and fourth (final) year pharmacy students undertaking their rural placement in the Gippsland region, in rural Victoria in 2011 and 2012.

RESULTS

Fifty-seven responses were returned (response rate = 98%). Students stated that understanding pharmacy practice from a rural perspective, visits to rural health professionals and sites and the attitude of their preceptors were essential to their satisfaction with their rural placements. A significant number of students (72%) intend to seek employment in rural areas if opportunities arise as a result of their increased rural awareness. The key components for a successful rural placement program were described by the surveyed students as social awareness, recognising job opportunities and interprofessional learning.

CONCLUSION

The evaluation of the rural placement program revealed that students valued their visits to rural sites and their interaction with other rural health professionals the most.

Willingness of Saudi dental professionals to treat Hepatitis B virus-infected patients

BACKGROUND

Hepatitis B virus (HBV) is considered the most important cross-infection hazard in developing countries. Patients infected with hepatitis virus could encounter difficulties in obtaining dental care. The aim of this study was to investigate the willingness of Saudi dental professionals to treat hepatitis B virus infected patients.

MATERIALS AND METHODS

This cross-sectional survey was carried out by distributing 300 questionnaires to Saudi dentists working in 40 government and private dental centers in Riyadh, Saudi Arabia. The questionnaire included questions related to age, sex, vaccination against HBV, screening for HBV antibody levels, willingness to treat hepatitis B infected patients, and the reasons behind any refusal. A t-test was used to compare the results and a P < 0.05 was considered significant.

RESULTS

Of the 300 distributed questionnaires, 274 were collected giving a response rate of 91%. The respondents were 212 males (77.4%) and 62 (22.6%) females. Only 10.2% of the Saudi dentists were willing to treat HB infected patients. The other dentists (89.8%) were unwilling to provide dental care for HB infected patients. Although 94.5% of the surveyed dentists were vaccinated against HBV, the main reason behind the refusal to treat HB infected patients (92.3%) was the risk of cross infection.

CONCLUSION

High percentages of Saudi dentists are unwilling to treat HBV-infected patients due to their apprehension about risk of cross infection. Many of the Saudi dentists do not screen for HBV antibody levels. All vaccinated dentists should carefully monitor their antibody levels to evaluate the need for booster doses. There is a need for educational programs to change the attitude of dentists toward treating HBV-infected patients. The strict adoption of cross infection preventive protocols by dentists will reduce the risk of transmitting infectious diseases in dental clinics as identification of blood-borne infections is not always possible.
