The paradox of safe milk supply by small-scale dairy farmers in sub-Saharan Africa: insights based on current practices in Malawi

Abstract This research paper aimed to assess milking and milk handling practices among small-scale dairy farmers and determine the presence of E. coli in raw and processed liquid milk in Malawi. A total of 113 dairy farmers were interviewed across three agroecological zones of Malawi. Eighty-seven (87) processed and raw milk samples were collected from selected food stores and dairy farms and tested for E. coli. Ninety-five percent of small-scale dairy farmers had at most 2 milking cows, with daily average milk production of less than 10 L. Sixty-nine percent cleaned milking utensils using untreated water, and the farmers had no refrigerators. Eighty-eight percent held raw milk for over 6 hours at room temperature. Escherichia coli was found to be widely distributed in raw milk (76%) and pasteurized milk (75%), averaging 5.38 ± 1.82 and 2.47 ± 1.02 log cfu/ml, respectively. In conclusion, this study demonstrates that Malawian small-scale dairy farmers employ poor milking and post-milking practices, which compromise the socioeconomic environment of small-scale dairy farmers.

The infected blood inquiry: Impact on public perceptions of blood supply risk, safety, and donation attitudes.

The UK's Infected Blood Inquiry (IBI) highlighted a major public health scandal, with at least 30 000 people infected and more than 3000 deaths attributable to infected blood and blood products. This study investigates the impact of the IBI announcement on May 20, 2024, on public perceptions of blood supply risk, safety, and donation intentions in the UK compared to the USA. A 2 (country: UK vs. USA) × 2 (time: pre-, post-IBI announcement) between-within-subject study was conducted with 1635 participants (888 UK, 747 USA). Pre-IBI data were collected from May 3 to 7, 2024, and post-IBI data from May 30 to June 30, 2024. Key measures were perceived infection risk from transfusion, transfusion safety, willingness to donate and encourage others. The impact was assessed using differences-in-differences (DiD) and reliable-change-indices (RCI). UK participants showed a significant but small decrease in perceived safety compared to USA participants, with 1 in 30 UK individuals perceiving a significant reduction in perceived transfusion safety. Decreases in perceived safety were associated with significant decreases in willingness to donate and encouragement of others in the whole sample and in USA participants and significant decreases in willingness to encourage others in UK participants. Older people reported a greater reduction in safety, and non-donors were more likely to be put off donating and not ask others to donate as a result of their perception that safety had been reduced. Overall, perceived safety decreased marginally in the UK general population. Future research should explore the long-term impacts of the IBI.

Development and Application of Reservoir Operation Method Based on Pre-Release Index for Control of Exceedance Floods

The pre-release operation has the potential to enhance the ability of a reservoir to manage exceedance floods. However, the mechanisms for the initiation and termination of such operations are unclear, and a clear method for calculating the pre-release water amount at each time step of the scheduling phase is lacking. To address this, the framework and mathematical expression for a pre-release index are proposed herein, and a refined pre-release scheduling model is developed based on the pre-release indices and their thresholds. Then, the proposed pre-release operation model is applied to the Shuifumiao Reservoir in the Lianshui River Basin in Hunan Province, China. The simulation results demonstrate that the refined pre-release scheduling model can effectively prevent exceedance floods, ensuring the safety of flood control without compromising the effectiveness of water supply safety. The proposed model provides a valuable framework and tool for enhancing the ability of reservoir operators to manage flood events and improve overall flood control safety.

Blood donation practices, motivators and barriers in the Caribbean: A narrative review.

Adequacy and safety are the twin prerogatives of the blood transfusion service which in turn is an indispensable component of public health delivery; however, many Caribbean countries have inadequate blood supply for the current and projected demands of their health care systems. Understanding blood donor motivators and barriers is crucial to improving the rate of voluntary non-remunerated blood donation (VNRD) to meet World Health Organisation (WHO) targets. The objective of this study was to review current research on the landscape of blood donation practices and attitudes in the Caribbean. We undertook a systematic search of electronic databases through September 2023 to identify studies of blood donation practices, knowledge and attitudes, including motivators and barriers to donation in the English-speaking Caribbean. We identified eight (8) relevant studies of observational study design. VNRD remain relatively uncommon; family replacement or remunerated donations were most common. Barriers to blood donation included lack of a known recipient such as a family member who needed blood, never having been asked to donate, presumed ineligibility to donate, and fear of needles or adverse reactions. Study participants indicated willingness to donate blood if provided more information about the importance of blood donation. There is a paucity of published research regarding blood donor knowledge, motivators and barriers in the Caribbean context. Such research could indicate the necessary interventions for achieving the goals of an adequate and safe blood supply.

Pork as a Source of Diverse Viral Foodborne Infections: An Escalating Issue

This review synthesizes current knowledge on the risks posed by viral foodborne infections associated with pork, emphasizing their global prevalence and the complexity of managing such pathogens. It covers a range of significant viruses, including hepatitis A and E, norovirus, rotavirus, sapovirus, enterovirus, astrovirus, and enteric adenovirus. The role of pigs as reservoirs for diverse pathogens with zoonotic potential further complicates safety challenges, extending risks to individuals involved in pork production and processing. Various factors influencing viral contamination throughout the meat production chain are explored, from farm-level practices to processing and handling procedures. Emphasis is placed on the critical importance of implementing effective control measures at each stage, including enhanced biosecurity, rigorous hygiene practices, and appropriate thermal processing techniques. Additionally, the need for improved surveillance and detection methods to effectively identify and monitor viral presence in meat products is highlighted. In conclusion, the necessity of adopting a One Health approach that integrates efforts in animal health, food safety, and public health to mitigate the risks of viral foodborne infections associated with meat consumption is underscored. This holistic strategy is essential for safeguarding consumer health and ensuring the safety of the global food supply.

Unscrambling why plastics aren't detectable in chicken eggs

Several food groups have been reported to contain varying concentrations of plastics. This study was designed to quantitatively investigate for the first time in Australia the presence of plastics in store-bought chicken eggs. Three commonly consumed brands of free-range, free-range organic, barn-laid and backyard (home-laid) chicken egg samples were analyzed for seven common polymers (i.e., polypropylene, polyethylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, poly-(methylmethacrylate) and polycarbonate). Samples were extracted by enzyme digestion and pressurized liquid extraction, followed by quantitative analysis through double-shot microfurnace pyrolysis coupled to gas chromatography-mass spectrometry. No plastics were detected at concentrations > limit of detection (LOD) (from 0.04 μg/g for PS to 0.22 μg/g for PVC) in the egg samples analyzed, regardless of brand and category, suggesting limited exposure of Australians to plastics from consuming eggs This study provides valuable baseline data and underscores the importance of continued monitoring to ensure the safety and integrity of food supplies in the face of rising environmental plastic pollution.

Influences on improved confidence among allied health students in working with Australian Indigenous people during a rural placement: a pre-post survey study

BackgroundTogether with addressing social determinants of health, culturally safe healthcare provision is essential for closing the health outcomes gap experienced by Aboriginal and Torres Strait Islander (Indigenous) Australians. Rural placements potentially provide students of the health professions with opportunities to enhance their knowledge and skills regarding cultural safety. We used rural placements data systematically collected from allied health students, including commencement- and end-of-placement questionnaire responses, to investigate the determinants of confidence in working with Indigenous people.MethodsThe study comprised data from all students who provided survey data at both commencement and end of their first placement directly supervised by the administering University Department of Rural Health during the period 2019–2022. Five-point ordered responses to the question ‘How confident do you feel about working with Aboriginal people?’ were used to assess student and placement-related determinants of confidence (Confident/Very confident versus other) at baseline and increased confidence (≥ 1 point) during the placement using crude and adjusted multivariable robust Poisson regression.ResultsParticipating students (N = 489) were from diverse allied health disciplines (including pharmacy n = 94, 19.2%; chiropractic n= 66, 13.5%; physiotherapy n= 65, 13.3%; social work n = 59, 12.1%; and occupational therapy 58, 11.9%). Confidence in dealing with Aboriginal people was lower at commencement among females compared with males (adjusted relative risk [aRR] 0.65; 95% confidence interval [CI] 0.53–0.80), and higher among students of Australian rural origin compared with others (aRR 1.49; CI 1.22–1.83) and those who reported previous experience working with Indigenous people compared with those reporting none (aRR 1.40; CI 1.14–1.72). Placement attributes associated with increased confidence working with Indigenous people between placement commencement and end were interaction with Indigenous people within the placement (aRR 2.32; CI 1.24–4.34), placement model reflecting more structured academic supervision (aRR 1.18; CI 1.02–1.37), and placement length (aRR per additional day 1.002; CI 1.001–1.004). These associations were robust to modelling that accounted for a ceiling effect on increased confidence.ConclusionsWhile influenced by students’ demographic attributes and prior experiences, confidence of allied health students in working with Indigenous people is enhanced during rural placements, particularly through direct contact with Indigenous people.

Developing a human monoclonal antibody combination CRM25 to prevent rabies after exposure.

Immunization against rabies post-exposure prophylaxis (PEP) requires passive immunization with either monoclonal antibody (mAb) or blood-derived rabies immunoglobin (RIG). Currently, replacing traditional RIG with emerging mAb or mAb combinations is highly recommended due to the limited supply and potential safety risks of RIG. Here, we developed a mAb combination named CRM25 by combining two human mAbs, RM02 and RM05, at a 1:1 mass ratio. RM02 and RM05 were non-competing and non-overlapping mAbs targeting epitopes I and III, respectively. K226 and G229 were found to be the critical amino acid sites for RM02 neutralization, but the mutant I338T displayed decreased susceptibility to RM05 neutralization. Notably, CRM25 was capable of cross-neutralizing rabies virus (RABV) strains containing K226M or I338T mutations. CRM25 additionally showed an inhibitory effect on the infection of all tested common RABVs and non-RABV phylogroup I lyssaviruses. CRM25 not only exhibited neutralizing activity but also exhibited antiviral effects via Fc-mediated effector functions. Importantly, CRM25 was comparable to human RIG in terms of its capacity to protect Syrian golden hamsters from lethal RABV challenges. These findings promote more thorough research on CRM25's antiviral properties in cells and in vivo to enhance its clinical applicability and suggest that it may be a viable candidate medication for rabies PEP.

Clinicians' Perspectives and an Ethical Analysis of Safer Supply Opioid Prescribing.

In British Columbia, Canada, many physicians providing care to individuals with high-risk opioid use disorder adopted safer supply (SS) opioid prescribing in the spring of 2020 with the goal of facilitating public health measures for COVID-19. This prescribing practice continued after measures were lifted. This study aimed to explore prescribers' perspectives following several years of local experience in prescribing SS opioids, primarily in the form of hydromorphone tablets, and to apply ethical concepts to explore current challenges and ongoing sources of provider distress. Addiction medicine SS prescribers participated in individual or small group semi-structured interviews. Each interview was transcribed and analysed for recurrent themes. Themes were then integrated into a narrative ethics discussion. Eleven addiction medicine physicians practicing in various settings within Vancouver participated in this study. Six themes were identified: clinical assessment, clinician distress, gaps in care, models of safer supply, research, and special populations. Ethical dilemmas in prescribing SS are identified and explored through a discussion of biomedical ethics principles and the physician role.

Prevalence, incidence, and residual risk for human immunodeficiency virus among blood donors from 2003 to 2022 in Guangzhou, China.

China's significant population affected by HIV poses a substantial threat to blood transfusion safety. Despite advancements in blood testing techniques, a residual risk of HIV transmission persists. Accurately assessing HIV epidemic and the residual risk is vital for monitoring blood supply safety and evaluating the effectiveness of new screening tests. We conducted a retrospective analysis of HIV detection results among voluntary blood donors from 2003 to 2022. The study included data on HIV-confirmed positive donors, HIV prevalence, infection risk factors, and an incidence-window period mathematical model to estimate the residual risk of HIV. Between 2003 and 2022, HIV prevalence among blood donors in Guangzhou showed a peak-shaped trend, initially increasing before declining. The overall HIV prevalence was 18.9 infections per 100,000 donations. Male donors had a significantly higher prevalence compared with female donors. Donors aged 26-35 years had the highest prevalence. Ethnic minority donors had a higher prevalence compared with Han donors. Repeat donors had a lower prevalence compared with first-time donors. Donors from other provinces had a higher prevalence compared with local donors. During the period of 2003 to 2022, the residual risk of HIV in Guangzhou steadily decreased, reaching a notable 1 in 526,316 donations in the past two years. The HIV epidemic among blood donors in Guangzhou remains severe, but the residual risk of HIV is decreasing. Novel detection methods have proven advantageous in reducing this residual risk. Implementing additional effective measures is imperative to ensure blood safety and curb the spread of HIV.

Increasing the available water diversion volume of water source project through flood resource utilization: A case study of the middle route of the South-to-North water diversion project in China

Water supply operating rules are critical for guaranteeing the safety of the water supply in the source project and receiving areas and overcoming the uneven distribution of water resources among different regions. Previous studies have mainly focused on optimizing the water supply operating rules to balance multiple benefits under the current engineering design parameters. In this study, a framework is proposed in which the water supply operating rules for the resource reservoir are adapted through flood resource utilization. The correlations among seasonal floods are first analyzed by considering the influence of water diversion projects. The seasonal flood-limited water levels (FLWLs) are then re-designed in terms of a flood damage assessment index under the deduced most-probable seasonal floods. Finally, the water supply operating curves of the resource reservoir are optimized by adopting the recommended seasonal FLWLs. The middle route of the South-to-North Water Diversion Project in China is taken as a case study. The results show that the recommended seasonal FLWLs are 160.2 m in summer and 164.2 m in autumn, and that the annual average available water diversion volume can be increased by 0.52 billion m3 without increasing the flood risk. Compared with the current water supply operating rules, the optimal operating curves make the annual distribution of the available water diversion volume more uniform in different typical-year scenarios and reduce the surplus reservoir water. These findings are helpful for exploring the potential of water resource utilization.

The impact of the current medico-legal and regulatory culture in Ireland on the decision of graduate entry medical school students to pursue a career in obstetrics and gynecology

ObjectivesMedico-legal and regulatory culture has a significant impact on medical practitioners, including the decision of graduates to enter high-risk specialties. This study explores the impact of the current medico-legal and regulatory culture in Ireland on the decision of graduate entry medical students to enter one high risk specialty, obstetrics and gynecology. Study DesignWe conducted a survey of 146 final-year, graduate-entry medical students pre- and post- a 6-week rotation in obstetrics and gynecology in Ireland. Participants were asked to rate the influence (on a four-point scale) of factors such as fear of being sued, being reported to the regulatory body or criminal prosecution on their decision to pursue a career in obstetrics or gynaecology. Data were matched pre- and post-rotation and McNemar-Bowker’s test was used to test for differences in related data. All analysis was conducted using SPSS for Windows version 25. ResultsThe responses of 72 students to both questionnaires could be matched (response rate 49.3%). The majority of participants pre-rotation reported that fear of being sued (74%), fear of being reported to the regulatory body (70%) and fear of criminal prosecution (55%) were factors influencing their decision (somewhat or to a great extent) to pursue a career in obstetrics. There were no significant changes post-rotation. Compared to obstetrics, lower proportions of participants pre-rotation considered fear of being sued (54%), fear of being reported to the regulatory body (50%) and fear of criminal prosecution (40%) as factors influencing their decision to pursue a career in gynecology. There were no significant changes post-rotation. ConclusionsMedico-legal and regulatory culture is shaping the perceptions of graduate entry medical students of obstetrics and gynecology and influencing their decision to pursue a career in the speciality. Understanding the impact of medico-legal culture on career choices including a high-risk specialty such as obstetrics and gynecology is important from both a policy and reform context, and if the healthcare service is to recruit and retain adequate numbers to ensure the safe provision of healthcare.

Hot topic: Avian influenza subtype H5N1 in US dairy—A preliminary dairy foods perspective

In February and March of 2024, an unusual illness began affecting dairy herds primarily in Texas and neighboring states. The causative agent of this illness was ultimately confirmed in late March 2024 to be a strain of highly pathogenic avian influenza H5N1 belonging to clade 2.3.4.4b. In the months following the emergence of this viral disease in cattle, infections have spread to at least 191 herds in 13 states at the time of this writing in August 2024, primarily through cattle and human movement. Surprisingly, early examination of raw milk samples from clinically affected animals indicated that the virus had an affinity for the mammary tissue, and viral shedding into raw milk occurred at high levels, exceeding 108 log10 50% tissue culture infectious dose (TCID50) in some cases. These high viral loads coupled with evidence that farm cats who consumed raw milk from clinically ill animals were infected and exhibited high mortality rates, raised concerns about the safety of the US milk supply for human consumption. To date, 4 cow-associated human infections have been reported, all from farm employees with direct contact with infected animals. Several parameters ultimately affect the theoretical public health risk from consumption of dairy products manufactured from a milk supply containing H5N1, namely (1) initial viral load, (2) persistence of H5N1 in raw milk, (3) viral inactivation through processing practices including pasteurization, and (4) human susceptibility and infectious dose. In the short period since the emergence of this disease in dairy cattle in the United States, research has begun to answer these critical questions, although our knowledge is still quite limited at this time. Here we review the literature available from the current H5N1 outbreak in US dairy cattle, as well as selected relevant literature from previous research in other animal agriculture sectors, that affect our current understanding of the parameters associated with the food safety risk of this disease in the US dairy supply chain.

Protocol to Support Skin-to-Skin Care and Closeness Between Parents and Neonates in the NICU

Skin-to-skin care (SSC) is essential, can help to prevent separation of parents and the neonate in the NICU, and should be a standard practice. It can safely be integrated into the routine care of preterm neonates, those who require surgery, and those who require all levels of intensive care. Years of experience with the provision of SSC in our NICU influenced our approach to care and resulted in practice guidelines for the safe provision of SSC. In this article, we present our clinical practical guidelines that support SSC and closeness between parents and the neonate to ensure the use of these practices for all neonates in the NICU.

Understanding Blood Donation Practices in Gilgit, Pakistan An Anthropological Perspective

Blood is widely recognized as an essential bodily fluid crucial for sustaining life, and blood donation plays a critical role in saving lives. Ensuring access to a safe and sufficient supply of blood and its derivatives and reliable blood transfusion services is indispensable for a strong healthcare system. It is important to note that voluntary non-remunerated blood donors are the most reliable source of safe blood supply. In Pakistan, 70% of donated blood comes from replacement or paid donations, while only 10% comes from voluntary donations. In Gilgit, voluntary blood donation is scarce, and most blood comes from replacements. The respondents display limited understanding of blood transfusion, while they exhibit a positive attitude toward voluntary blood donation despite low participation. This discrepancy is attributed to inadequate awareness and campaigns, as well as prevalent myths and negative perceptions associated with blood and blood donation. Furthermore, sectarian-based segregation, the symbolic relationships between the donor and recipient and the exclusion of female blood donors exacerbate the gap between blood supply and demand. The research emphasises culturally suited solutions and strategies that can help enhance voluntary blood donation in Gilgit.

Modified McKissock Technique for Secondary Breast Reduction - A Prospective Study on Safety, Surgical and Aesthetic Outcomes.

Numbers of secondary breast reductions are increasing but those are potentially associated with higher complication rates than primary mammaplasty. Necrosis of the Nipple-Areola-Complex (NAC) is a devastating complication that can occur after repeated NAC transposition, particularly when the initially used pedicle is unknown. Thus, the authors established a modification of McKissock's technique for secondary breast reductions including three pedicle components to ensure safe vascular supply of the NAC. The presented technique incorporates a superior and inferior dermoglandular pedicle according to McKissock and an additional central pedicle. The technique was applied for secondary breast reduction in a series of 25 breasts (14 patients: 11 bilateral, 3 unilateral). Complication rates, pre- and postoperative BREAST-Q scores, and aesthetic outcomes were evaluated. Mean resection weight was 299 g (range, 40-646), and the NAC was transposed by 4.2 cm on average (range, 1-10). No case of NAC-necrosis was observed, and comparison of pre- and postoperative BREAST-Q values indicated substantial improvement in all domains. Postoperatively, 84.6% of patients reported excellent satisfaction with breast appearance. According to those results, the modified McKissock-technique is a safe technique for patients requiring secondary breast reduction, even if the primarily used pedicle is unknown. Additionally, the established technique is associated with improved postoperative patient-reported outcomes and yields aesthetically favorable results.

A Transformer-Based Approach to Leakage Detection in Water Distribution Networks.

The efficient detection of leakages in water distribution networks (WDNs) is crucial to ensuring municipal water supply safety and improving urban operations. Traditionally, machine learning methods such as Convolutional Neural Networks (CNNs) and Autoencoders (AEs) have been used for leakage detection. However, these methods heavily rely on local pressure information and often fail to capture long-term dependencies in pressure series. In this paper, we propose a transformer-based model for detecting leakages in WDNs. The transformer incorporates an attention mechanism to learn data distributions and account for correlations between historical pressure data and data from the same time on different days, thereby emphasizing long-term dependencies in pressure series. Additionally, we apply pressure data normalization across each leakage scenario and concatenate position embeddings with pressure data in the transformer model to avoid feature misleading. The performance of the proposed method is evaluated by using detection accuracy and F1-score. The experimental studies conducted on simulated pressure datasets from three different WDNs demonstrate that the transformer-based model significantly outperforms traditional CNN methods.

Alkoxy-functionalized covalent organic Framework membranes for efficient molecular sieving with high water permeance

The presence of various trace water-soluble organic pollutants, such as dyes, poses significant potential risks to human health and ecosystems. Membrane technology presents a promising and sustainable approach for their removal from aqueous environments. However, the amorphous structure of most commercial membranes makes it challenging to achieve effective separation with high water flux. Here, we present a novel series of hydrophilic COF membranes with different alkoxy sidechain lengths for the first time. These alkoxy sidechain functional COF membranes exhibit efficient rejection of water-soluble organic dyes, including rose bengal (> 50 %), congo red (> 98 %), brilliant blue R250 (> 99 %), and alcian blue (> 99 %). Moreover, these membranes demonstrate a high water flux exceeding 291.8 L m-2h−1 bar−1 and exceptional long-term operational stability lasting at least 2880 min. The superior performance of COF membranes is attributed to their optimal pore size, excellent hydrophilicity, and high crystallinity. This finding offers a promising approach for effectively eliminating water-soluble organic pollutants, thereby ensuring the safety and sustainability of the water supply.
