Working relationships between obstetric care staff and their managers: a critical incident analysis
Background
Malawi continues to experience critical shortages of key health technical cadres that can adequately respond to Malawi’s disease burden. Difficult working conditions contribute to low morale and frustration among health care workers. We aimed to understand how obstetric care staff perceive their working relationships with managers.
Methods
A qualitative exploratory study was conducted in health facilities in Malawi between October and December 2008. Critical Incident Analysis interviews were done in government district hospitals, faith-based health facilities, and a sample of health centres’ providing emergency obstetric care. A total of 84 service providers were interviewed. Data were analyzed using NVivo 8 software.
Results
Poor leadership styles affected working relationships between obstetric care staff and their managers. Main concerns were managers’ lack of support for staff welfare and staff performance, lack of mentorship for new staff and junior colleagues, as well as inadequate supportive supervision. All this led to frustrations, diminished motivation, lack of interest in their job and withdrawal from work, including staff seriously considering leaving their post.
Conclusions
Positive working relationships between obstetric care staff and their managers are essential for promoting staff motivation and positive work performance. However, this study revealed that staff were demotivated and undermined by transactional leadership styles and behavior, evidenced by management by exception and lack of feedback or recognition. A shift to transformational leadership in nurse-manager relationships is essential to establish good working relationships with staff. Improved providers’ job satisfaction and staff retentionare crucial to the provision of high quality care and will also ensure efficiency in health care delivery in Malawi
Cost-effectiveness of a mobile health-supported lifestyle intervention for pregnant women with an elevated body mass index
Objective To assess the cost-effectiveness of a mobile health-supported lifestyle intervention compared with usual care.
Methods We conducted a cost-effectiveness analysis from the perspective of the publicly-funded health care system. We estimated costs associated with the intervention and health care utilisation from first antenatal care appointment through delivery. We used bootstrap methods to quantify the uncertainty around cost‐effectiveness estimates. Health outcomes assessed in this analysis were gestational weight gain (GWG; kg), incidence of excessive GWG, quality-adjusted life years (QALYs), and incidence of large-for-gestational-age (LGA). Incremental cost-effectiveness ratios (ICERs) were calculated as cost per QALY gained, cost per kg of GWG avoided, cost per case of excessive GWG averted, and cost per case of LGA averted.
Results Total mean cost including intervention and health care utilisation was €3745 in the intervention group and €3471 in the control group (mean difference €274, P = 0.08). The ICER was €2914 per QALY gained. Assuming a ceiling ratio of €45,000, the probability that the intervention was cost‐effective based on QALYs was 79%. Cost per kg of GWG avoided was €209. The cost-effectiveness acceptability curve (CEAC) for kg of GWG avoided reached a confidence level of 95% at €905, indicating that if one is willing to pay a maximum of an additional €905 per kg of GWG avoided, there is a 95% probability that the intervention is cost-effective. Costs per case of excessive GWG averted and case of LGA averted were €2117 and €5911, respectively. The CEAC for case of excessive GWG averted and for case of LGA averted reached a confidence level of 95% at €7090 and €25,737, respectively.
Conclusions Results suggest that a mobile-health lifestyle intervention could be cost-effective; however, a better understanding of the short- and long-term costs of LGA and excessive GWG is necessary to confirm the results

Too few staff, too many patients: A qualitative study of the impact on obstetric care providers and on quality of care in Malawi
Background: Shortages of staff have a significant and negative impact on maternal outcomes in low-income countries, but the impact on obstetric care providers in these contexts is less well documented. Despite the government of Malawi's efforts to increase the number of human resources for health, maternal mortality rates remain persistently high. Health workers' perceptions of insufficient staff or time to carry out their work can predict key variables concerning motivation and attrition, while the resulting sub-standard care and poor attitudes towards women dissuade women from facility-based delivery. Understanding the situation from the health worker perspective can inform policy options that may contribute to a better working environment for staff and improved quality of care for Malawi's women. Methods: A qualitative research design, using critical incident interviews, was used to generate a deep and textured understanding of participants' experiences. Eligible participants had performed at least one of the emergency obstetric care signal functions a in the previous three months and had experienced a demotivating critical incident within the same timeframe. Data were analysed using NVivo software. Results: Eighty-four interviews were conducted. Concerns about staff shortages and workload were key factors for over 40% of staff who stated their intention to leave their current post and for nearly two-thirds of the remaining health workers who were interviewed. The main themes emerging were: too few staff, too many patients; lack of clinical officers/doctors; inadequate obstetric skills; undermining performance and professionalism; and physical and psychological consequences for staff. Underlying factors were inflexible scheduling and staff allocations that made it impossible to deliver quality care. Conclusion: This study revealed the difficult circumstances under which maternity staff are operating and the professional and emotional toll this exacts. Systems failures and inadequate human resource management are key contributors to the gaps in provision of obstetric care and need to be addressed. Thoughtful strategies that match supply to demand, coupled with targeted efforts to support health workers, are necessary to mitigate the effects of working in this context and to improve the quality of obstetric care for women in Malawi
Subtidal macrozoobenthos communities from northern Chile during and post El Niño 1997–1998
Despite a large amount of climatic and oceanographic information dealing with the recurring climate phenomenon El Niño (EN) and its well known impact on diversity of marine benthic communities, most published data are rather descriptive and consequently our understanding of the underlying mechanisms and processes that drive community structure during EN are still very scarce. In this study, we address two questions on the effects of EN on macrozoobenthic communities: (1) how does EN affect species diversity of the communities in northern Chile? and (2) is EN a phenomenon that restarts community assembling processes by affecting species interactions in northern Chile? To answer these questions, we compared species diversity and co-occurrence patterns of soft-bottoms macrozoobenthos communities from the continental shelf off northern Chile during (March 1998) and after (September 1998) the strong EN event 1997–1998. The methods used varied from species diversity and species co-occurrence analyses to multivariate ordination methods.
Our results indicate that EN positively affects diversity of macrozoobenthos communities in the study area, increasing the species richness and diversity and decreasing the species dominance. EN represents a strong disturbance that affects species interactions that rule the species assembling processes in shallow-water, sea-bottom environments
Ageism and sexuality
Sexuality remains important throughout a person’s life, but sexual behavior does not receive the same levels of acceptance at all ages. Older people are challenged by ageist attitudes and perceptions that hinder their sexual expression. They are stereotyped as non-sexual beings who should not, cannot, and do not want to have sexual relationships. Expressing sexuality or engaging in sexual activity in later life is considered by many in society as immoral or perverted. False expectations for older people also stem from ideals of beauty, centralization of the biomedical perspective on sexuality of older adults, and the association of sex with reproduction. Unfortunately, older people internalize many ageist attitudes towards sexuality in later life and become less interested in sex and less sexually active. The following chapter explores attitudes towards sexuality in later life among the media, young people, older people themselves, and care providers. In order to enable older people to express their sexuality and sexual identity freely and fully, awareness of ageist perceptions must be raised and defeated
Inhibition of Listeria monocytogenes by Phage Lytic Enzymes Displayed on Tailored Bionanoparticles
The high mortality rate associated with Listeria monocytogenes and its ability to adapt to the harsh conditions employed in food processing has ensured that this pathogen remains a serious problem in the ready-to-eat food sector. Bacteriophage-derived enzymes can be applied as biocontrol agents to target specific foodborne pathogens. We investigated the ability of a listeriophage endolysin and derivatives thereof, fused to polyhydroxyalkanoate bionanoparticles (PHA_BNPs), to lyse and inhibit the growth of L. monocytogenes. Turbidity reduction assays confirmed the lysis of L. monocytogenes cells at 37 °C upon addition of the tailored BNPs. The application of BNPs also resulted in the growth inhibition of L. monocytogenes. BNPs displaying only the amidase domain of the phage endolysin were more effective at inhibiting growth under laboratory conditions (37 °C, 3 × 107 CFU/mL) than BNPs displaying the full-length endolysin (89% vs. 83% inhibition). Under conditions that better represent those found in food processing environments (22 °C, 1 × 103 CFU/mL), BNPs displaying the full-length endolysin demonstrated a greater inhibitory effect compared to BNPs displaying only the amidase domain (61% vs. 54% inhibition). Our results demonstrate proof-of-concept that tailored BNPs displaying recombinant listeriophage enzymes are active inhibitors of L. monocytogenes.fals

This report provides the main results and findings of the nineteenth annual underwater television survey on the Aran, Galway Bay and Slyne head Nephrops grounds, ICES assessment area; Functional Unit 17. The survey was multi-disciplinary in nature collecting UWTV, CTD and other ecosystem data. In 2020 a total of 44 UWTV stations were successfully completed, 34 on the Aran Grounds, 5 on Galway Bay and 5 on Slyne Head patches. The mean burrow density observed in 2020, adjusted for edge effect, was medium at 0.29 burrows/m². The final krigged burrow abundance estimate for the Aran Grounds was 359 million burrows with a CV (Coefficient of Variance; relative standard error) of 4%. The final abundance estimate for Galway Bay was 27 million and for Slyne Head was 7 million, with CVs of 13% and 4% respectively. The total abundance estimates have fluctuated considerably over the time series. The 2020 combined abundance estimate (394 million burrows) is 20% lower than in 2019, and it is below the MSY Btrigger reference point (540 million burrows). Using the 2020 estimate of abundance and updated stock data implies catches between 443 and 508 tonnes in 2021 that correspond to the F ranges in the EU multi annual plan for Western Waters, assuming that discard rates and fishery selection patterns do not change from the average of 2017–2019. Virgularia mirabilis was the only sea-pen species observed on the UWTV footage. Trawl marks were present at 7% of the Aran stations surveyed
Diet quality and blood pressure among pregnant women with overweight or obesity: A secondary analysis of two randomized controlled trials
Introduction: Maternal obesity is a significant risk factor for hypertensive disorders of pregnancy. High diet quality may protect against this, yet data regarding the relationship between diet quality and blood pressure among pregnant women with raised body mass index (BMI) is limited. Material and methods: This is a secondary analysis (n = 543) of women with BMI ≥25 kg/m2 from two randomized controlled trials; PEARS (Pregnancy Exercise and nutrition Research Study with smartphone application support) and ROLO (Randomized cOntrol trial of LOw glycemic index diet to prevent macrosomia in euglycemic women). Blood pressure was measured at 10–18 weeks and 28 weeks of pregnancy. Mean arterial pressure was calculated as (diastolic blood pressure (Formula presented.) [systolic blood pressure (Formula presented.) diastolic blood pressure]). Diet quality was assessed using 3-day food diaries, and Alternative Healthy Eating Index for Pregnancy (AHEI-P) scores were generated, quantifying alignment of food intakes with dietary guidelines in first and early third trimesters. The cohort was divided based on AHEI-P tertiles to explore differences at an alpha significance value of \u3c0.05. Results: The mean age of the group was 32.21 ± 4.39 years with a median body mass index (BMI) of 28.13 (IQR 3.47) kg/m2. Mean arterial pressures in the first and third trimesters were 81.07 ± 9.00 mmHg and 82.33 ± 7.53 mmHg, respectively. Rates of elevated blood pressure (≥120/80 mmHg) were 22.33% in trimester 1 and 24.48% in early trimester 3. Mean AHEI-P scores in trimester 1 and early trimester 3 were 53.90 ± 10.43 and 54.05 ± 10.76, respectively. There was no correlation between AHEI-P score and blood pressure and no differences in blood pressure between AHEI-P tertiles at either timepoint (all P-values \u3c0.05). A higher proportion of those with elevated early third trimester blood pressure had a BMI of ≥30 kg/m2 compared with those with normal blood pressure (40.31% vs 28.64%, P = 0.016). Conclusions: While diet remains an important factor in maternal health and wellbeing, we did not find a relationship between diet quality as measured by AHEI-P and blood pressure among pregnant women with BMI ≥25 kg/m2. High BMI remains a risk factor for hypertensive disorders of pregnancy
