Abstract Background There is critical need to strengthen the global nursing and midwifery workforce. This is especially true in Malawi where they are the primary providers of obstetric and neonatal care. In Neno district, Malawi, in 2017, we implemented an intensive training and longitudinal bedside mentorship intervention for nurses and midwives. From inception, there was a pre-planned project target completion after 5 years, including a staged handover to local ownership after 3 years. The objective of this study was to assess differences in reported maternal and neonatal complications following project completion and handover to local leadership. Methods The project was a partnership between an academic institution and local nongovernmental organization. In October 2020, the intervention was handed over and maintained by the local organization with limited support from the academic institution. Data from January 2019 to May 2023 were extracted from the Malawi District Health Information Software 2. Bivariate analyses explored differences in the pre- and post-handover periods for all government-collected, birth-related variables. The “pre-handover” period encompassed January 2019 to September 2020 and “post-handover” from October 2020 to May 2023. Multivariate linear regression explored outcomes while controlling for health facility. Results Data were collected from 10 health facilities in the district and included a total of 23,259 births. Overall, there were few significant changes between periods. Exceptions were in reporting of antepartum hemorrhage (p

This paper explores the intricate interplay of racism, trauma, and identity in Toni Morrison's novel, "The Bluest Eye." It delves into the challenges faced by African Americans within a predominantly white society by utilizing current trauma theory and black feminist concepts. The theoretical framework includes cultural trauma theories, including the contributions from Schreiber and insights from feminist thinkers like Bell Hooks and Patricia Hill Collins. Moreover, through an intersectional analysis, this study scrutinizes how gender, racial, class, and generational trauma intertwine to mold individuals' experiences and self-perception. Therefore, by amalgamating trauma theories with feminist perspectives, this paper provides valuable insights into the struggles of the characters and the societal dynamics portrayed in Morrison's novel, "The Bluest Eye."

There is a growing global recognition that community development has the potential to enhance the socio-economic status of resource-constrained rural communities. Many countries have established commu­nity development initiatives in rural areas to reduce pov­erty and improve social investment. However, numer­ous challenges hinder the implementation of community development initiatives that contribute to poverty re­duction in most of Southern Africa. The United Nations Sustainable Development Goals (SDGs), particularly Goal 1, mandates all countries to end all forms of pov­erty by the year 2030. One approach to achieving this goal is to devise and implement sustainable community development initiatives. This review paper presents some best practices for how community development in­itiatives could reduce poverty in Southern Africa. The lit­erature collected from government reports, accredited journal articles, and other credible scientific writings from 2000 to 2022 was reviewed to triangulate sources of information and understand the state of community de­velopment initiatives. Several challenges were found to impede progress in poverty reduction and negatively impact sustainable community development. The effec­tiveness and sustainability of poverty reduction strate­gies implemented by countries in Southern Africa vary widely from country to country and within the country itself. The study provides recommendations and best practice models implemented within rural communities in Southern Africa.

Abstract Malawi experienced its deadliest Vibrio cholerae (Vc) outbreak following devastating cyclones, with >58,000 cases and >1700 deaths reported between March 2022 and May 2023. Here, we use population genomics to investigate the attributes and origin of the Malawi 2022–2023 Vc outbreak isolates. Our results demonstrate the predominance of ST69 clone, also known as the seventh cholera pandemic El Tor (7PET) lineage, expressing O1 Ogawa (~ 80%) serotype followed by Inaba (~ 16%) and sporadic non-O1/non-7PET serogroups (~ 4%). Phylogenetic reconstruction revealed that the Malawi outbreak strains correspond to a recent importation from Asia into Africa (sublineage AFR15). These isolates harboured known antimicrobial resistance and virulence elements, notably the ICEGEN/ICEVchHai1/ICEVchind5 SXT/R391-like integrative conjugative elements and a CTXφ prophage with the ctxB7 genotype compared to historical Malawian Vc isolates. These data suggest that the devastating cyclones coupled with the recent importation of 7PET serogroup O1 strains, may explain the magnitude of the 2022–2023 cholera outbreak in Malawi.

Abstract Growth in the green jobs sector has increased demand for college graduates who are prepared to enter the workforce with interdisciplinary sustainability skills. Simultaneously, scholarly calls for interdisciplinary collaboration in the service of addressing the societal challenges of enhancing resilience and sustainability have also increased in recent years. However, developing, executing, and assessing interdisciplinary content and skills at the post-secondary level has been challenging. The objective of this paper is to offer the Food-Energy-Water (FEW) Nexus as a powerful way to achieve sustainability competencies and matriculate graduates who will be equipped to facilitate the transformation of the global society by meeting the targets set by the United Nations Sustainable Development Goals. The paper presents 10 curricular design examples that span multiple levels, including modules, courses, and programs. These modules enable clear evaluation and assessment of key sustainability competencies, helping to prepare graduates with well-defined skillsets who are equipped to address current and future workforce needs.

Abstract Background Especially in high HIV prevalence contexts, such as Zambia, effective biomedical prevention tools are needed for priority populations (PPs), including key populations (KPs), who are at higher risk. HIV pre-exposure prophylaxis (PrEP) has been scaled up nationally in Zambia, but little is known about barriers to PrEP use among specific PPs to date. Methods To understand barriers and facilitators to PrEP use in Zambia, we conducted a qualitative case study of PrEP services to PPs including sero-discordant couples (SDCs), female sex workers (FSWs), and men who have sex with men (MSM) in Livingstone. The study conducted in 2021 included in-depth interviews (n = 43) guided by the socio-ecological model, and focus group discussions (n = 4) with clinic and community-based providers and PrEP-eligible clients including users and non-users across PP groups. We used thematic analysis to analyze data using codes derived both deductively and inductively. Results We found multilevel barriers and facilitators to PrEP use. Cross-cutting barriers shared across PP groups included amplifying effects of PrEP being mistaken for antiretroviral drugs used to treat HIV, including anticipated stigma, and concerns about side-effects based on both misinformation and experience. In addition, stigmatized identities, particularly that of MSM, served as a barrier to PrEP use. The fear of being mislabeled as having HIV was of greatest concern for FSWs. Facilitators to PrEP use primarily included the importance of confidential, KP-sensitive services, and the role of informed, supportive family, friends, and peers. Participants across all PP groups urged expanded education efforts to increase awareness of PrEP within the general population toward mitigating concerns of being mislabeled as living with HIV. Conclusion To our knowledge, this is the first qualitative study of the PrEP cascade among multiple PPs in Zambia. This study provides important explanation for the low rates of PrEP continuation found in earlier demonstration trials among KPs in Zambia. The study also offers recommendations for programming efforts going forward such as inclusive PrEP awareness campaigns, expanded KP sensitivity training, and related efforts to thwart PrEP stigma while expanding access.

BackgroundThis pilot study evaluates the effectiveness of mobile talk-time incentives in maintaining participation in a longitudinal mobile health (mHealth) data collection program among people living with HIV in Lusaka, Zambia. While mHealth tools, such as mobile phone surveys, provide vital health feedback, optimal incentive strategies to ensure long-term engagement remain limited. This study explores how different incentive levels affect response rates in multiple survey rounds, providing insights into effective methods for encouraging ongoing participation, especially in the context of Zambia’s prepaid mobile system and multi-SIM usage, a common practice in sub-Saharan Africa. ObjectiveThis study aimed to assess the response rate success across multiple invitations to participate in a care experience survey using a mobile phone short codes and unstructured supplementary service data (USSD) model among individuals in an HIV care setting in the Lusaka, Zambia. MethodsParticipants were recruited from 2 study clinics–1 in a periurban setting and 1 in an urban setting. A total of 2 rounds of survey invitations were sent to study participants on a 3-month interval between November 1, 2018, and September 23, 2019. Overall, 3 incentive levels were randomly assigned by participant and survey round: (1) no incentive, (2) 2 Zambian Kwacha (ZMW; US $0.16), and (3) 5 ZMW (US $0.42). Survey response rates were analyzed using mixed-effects Poisson regression, adjusting for individual- and facility-level factors. Probability plots for survey completion were generated based on language, incentive level, and survey round. We projected the cost per additional response for different incentive levels. ResultsA total of 1006 participants were enrolled, with 72.3% (727/1006) from the urban HIV care facility and 62.4% (628/1006) requesting the survey in English. We sent a total of 1992 survey invitations for both rounds. Overall, survey completion across both surveys was 32.1% (637/1992), with significantly different survey completion between the first (40.5%, 95% CI 37.4-43.6%) and second (23.7%, 95% CI 21.1-26.4) invitations. Implementing a 5 ZMW (US $0.42) incentive significantly increased the adjusted prevalence ratio (aPR) for survey completion compared with those that received no incentive (aPR 1.35, 95% CI 1.11-1.63). The cost per additional response was highest at 5 ZMW, equivalent to US $0.42 (72.8 ZMW [US $5.82] per 1% increase in response). ConclusionsWe observed a sharp decline of almost 50% in survey completion success from the initial invitation to follow-up survey administered 3 months later. This substantial decrease suggests that longitudinal data collection potential for a care experience survey may be limited without additional sensitization and, potentially, added survey reminders. Implementing a moderate incentive increased response rates to our health care experience survey. Tailoring survey strategies to accommodate language preferences and providing moderate incentives can optimize response rates in Zambia.

Objectives: Total hip arthroplasty is a successful procedure for treating advanced osteoarthritis (OA). Metal bearing surfaces remain one of the most widely implanted prosthesis, however approximately 10% of patients develop adverse local tissue reactions (ALTRs), namely lymphocytic predominant soft tissue reaction with or without necrosis and osteolysis resulting in high revision rates. The mechanism(s) for these reactions remains unclear although T lymphocyte mediated type IV hypersensitivity to cobalt (Co) and chromium (Cr) ions have been described. The purpose of this study was to determine the prolonged effects of Co and Cr metal ions on synovial fibroblasts to better understand the impact of the synovial membrane in the development of ALTRs. Methods: Human synovial fibroblast-like cells were isolated from donors undergoing arthroplasty. DNA content and Alamar blue assay were used to determine cellular viability against exposure to Co and Cr. A beta-galactosidase assay was used to determine the development of cellular senescence. Western blotting and RT-qPCR were employed to determine changes in senescent associated secretory factors, signaling and anti-oxidant enzyme expression. A fluorescent assay was used to measure accumulation of hydrogen peroxide. Results: We demonstrate that prolonged cobalt exposure results in a downregulation of the enzyme catalase resulting in cytosolic accumulation of hydrogen peroxide, decreased Akt activity and cellular senescence. Senescent fibroblasts demonstrated upregulation of proinflammatory cytokines IL-1β and TNFα in addition to the neurotrophic factor NGF. Conclusion: Our results provide evidence that metal ions induce a senescent associated secretory phenotype in synovial fibroblasts that could contribute to the development of adverse local tissue reactions.

Abstract Background Critically ill children require close monitoring to facilitate timely interventions throughout their hospitalisation. In low- and middle-income countries with a high disease burden, scarce paediatric critical care resources complicates effective monitoring. This study describes the monitoring practices for critically ill children in a paediatric high-dependency unit (HDU) in Malawi and examines factors affecting this vital process. Methods A formative qualitative study based on 21 in-depth interviews of healthcare providers (n = 12) and caregivers of critically ill children (n = 9) in the HDU along with structured observations of the monitoring process. Interviews were transcribed and translated for thematic content analysis. Results The monitoring of critically ill children admitted to the HDU was intermittent, using devices and through clinical observations. Healthcare providers prioritised the most critically ill children for more frequent monitoring. The ward layout, power outages, lack of human resources and limited familiarity with available monitoring devices, affected monitoring. Caregivers, who were present throughout admission, were involved informally in monitoring and flagging possible deterioration of their child to the healthcare staff. Conclusion Barriers to the monitoring of critically ill children in the HDU were related to ward layout and infrastructure, availability of accurate monitoring devices and limited human resources. Potential interventions include training healthcare providers to prioritise the most critically ill children, allocate and effectively employ available devices, and supporting caregivers to play a more formal role in escalation.

Traditionally, doctoral studies take at least three to six years of full-time study, depending on the country and institution. However, the number of doctoral students who complete their studies in the prescribed time does not meet the expectations of the scientific community. Many students who enrol in a doctoral programme either drop out or do not complete it within the expected time frame. The literature is replete with evidence of the challenges faced by early career researchers, but there is still little reported on how to bridge the existing and perceived barriers that continue to undermine doctoral study retention. These and other obstacles must be addressed and combated by questioning the root causes of students dropping out of their studies. Thus, this study sought to suggest pathways to overcome these and other obstacles by providing a coherent overview of what we need to do and how. The methodology used included a thorough review of international accredited peer reviewed articles extracted from the SCOPUS multidisciplinary database. A total of 24 articles relevant to the topic were thus selected. The key finding of this initiative is that doctoral students face wide-ranging financial, academic, and social challenges that need to be addressed innovatively to improve the timely realisation of the successful completion of their studies.

Vaccination is one of the greatest public health achievements of the 20th century, with a tremendous impact in the prevention and control of diseases. However, the recent reemergence of vaccine-preventable diseases calls for a need to evaluate current vaccination practices and disparities in vaccination between high-income countries and low-and-middle-income countries. There are massive deficits in vaccine availability and coverage in resource-constrained settings. Therefore, this perspective seeks to highlight the reemergence of vaccine-preventable diseases in Africa within the lens of health equity and offer recommendations on how the continent should be prepared to deal with the myriad of its health systems challenges. Among the notable factors contributing to the reemergence, stand health inequities affecting vaccine availability and the dynamic vaccine hesitancy. Strengthening health systems and addressing health inequities could prove useful in halting the reemergence of vaccine-preventable diseases.

ABSTRACTAnaesthetics in aquaculture serve as a stress avoidance mechanism, mitigating stress-related impacts during fish handling and transportation. This study assessed the efficacy of sodium bicarbonate and clove stem powder as anaesthetic agents for Nile Tilapia juveniles. Four hundred and twenty uniform O. niloticus juveniles (5 ± 0.5 g, 74 ± 5 mm) were exposed to varying concentrations of sodium bicarbonate (10, 15, 20, 25, 30, 35, 40 g/L) and clove stem powder (0, 1, 3, 5, 7, 10, 15 g/L) in 20 L transparent plastic tanks. The results showed an inverse relationship between anaesthetic concentration and induction time, a direct relationship with recovery time, and an inverse correlation between induction and recovery times for both agents (P

The Southern Ground-hornbill (SGH) (Bucorvus leadbeateri) is considered an umbrella species for biodiversity conservation in savannah biomes since they require large territories and significant protection measures that help to conserve a wide range of biodiversity with similar savanna and grassland requirements. Declines of the species are attributed to low reproductive rates coupled with multiple anthropogenic threats, including secondary poisoning, and persecution. Little is known about connectivity and population structure of SGH populations in Africa, south of the equator. Knowledge of population differentiation is needed to ensure that targeted conservation management plans can be implemented to slow population declines and ensure survival of the species. To inform a long-term conservation strategy, we investigated the broad-scale population structure of Southern Ground-hornbill across their sub-equatorial range. Our study based on 16 microsatellite loci identified moderate variation (average of 5.889 alleles per locus and a mean observed heterozygosity of 0.546) similar to other long-lived avian species. In contrast, mitochondrial DNA sequences analysis identified low diversity (Hd = 0.3313, π = 0.0015). A Bayesian assignment approach, principal component analysis, analysis of molecular variance and phylogenetic analysis identified weak to moderate population structuring across long distances and mitochondrial data showed a shallow phylogeny. Restriction to long-distance dispersal was detected that could not be attributed to isolation by distance, suggesting that other factors, such as their dispersal biology, are shaping the observed genetic differentiation. Although our study does not support the designation of populations as independent conservation units, we advocate that population management should continue to follow the Precautionary Principle (mixing founders from the same range state, rather than allowing mixing of founders from the extremes of the range) until there is scientific certainty. Following further research, if no independent conservation units are detected, then the global captive population can contribute to reintroductions across the range. In the wild, populations at the edge of the species range may need additional management strategies and gene flow should be promoted between neighbouring populations.

Background: As urban populations rapidly expand across sub-Saharan Africa, promoting sustainable and efficient transportation systems is imperative for fostering economic growth and social inclusion by enhancing mobility and accessibility. Objectives: This study examines the travel mode choices and factors influencing the use of these modes among residents of Lusaka, Zambia, for their work or school trips. Method: A household survey ascertained mode choice, trip characteristics, and transportation challenges experienced. Descriptive, contingency table, and post hoc analyses explored relationships between mode and associated factors. Results: Public buses emerged as the predominant mode for work/school trips, followed by walking and private cars, highlighting public transit’s and non-motorised transport’s importance. However, travel behaviour varied significantly by residential density. High-density areas favoured public transit and walking, while low-density areas promoted greater private vehicle use, highlighting the influence of urban form on mode choice. Key mode choice factors included travel time, fares and safety, though environmental concerns had lesser impact. Crucially, socio-economic and demographic characteristics like age, gender, income, education, employment, car ownership, trip purpose, household composition, presence of children, and destination accessibility significantly influenced mode choices, revealing the complex interplay shaping mobility patterns. Conclusion: Findings underscore the need for policy interventions investing in public transportation infrastructure, enhancing pedestrian and cycling facilities, and prioritising walkability in urban planning to encourage sustainable transportation behaviours. Contribution: This study contributes to the discourse on urban sustainability by highlighting the importance of integrating social, economic, and environmental considerations into transportation planning and policymaking processes.

Introduction The escalating consumption of ultra-processed foods (UPFs) among school-aged children in developing countries poses a significant threat to public health, contributing to the dual burden of malnutrition. In Malawi, where undernutrition coexists with a burgeoning obesity epidemic, understanding the determinants of UPF consumption and its impact on children’s nutritional status is imperative. This study, conducted in Lilongwe, Malawi, aimed to investigate the association between UPF consumption, sociodemographic factors and the nutritional status of school-aged children.Materials and methods 511 children aged 7–14 were recruited from 2 densely populated townships using systematic random sampling. Data on sociodemographic factors, UPF consumption and nutritional status were collected through face-to-face interviews and anthropometric measurements. UPF consumption was assessed using a validated Food Frequency Questionnaire while multinomial logistic regression was employed to analyse associations.Results Results revealed alarmingly high UPF consumption among children, particularly those high in sugar. Multinomial logistic regression identified significant predictors of malnutrition outcomes. Notably, children consuming UPFs more than three times a week were more likely to be malnourished. Overweight status was positively associated with sausage intake (β=0.226, adjusted OR 1.254, 95% CI 1.004 to 1.566, p=0.046) and age (β=0.020, adjusted OR=0.257, 95% CI 0.156 to 0.28, p=0.003). Conversely, underweight status was linked with residential location (β=4.507, adjusted OR 0.01, 95% CI 0.000 to 0.281, p=0.006) and fizzy drinks (β=1.071, adjusted OR 2.919, 95% CI 1.413 to 6.028, p=0.004).Conclusion The high prevalence of UPF consumption among school-aged children is significantly associated with malnutrition. Moreover, sociodemographic factors influence UPF consumption, highlighting the need for targeted interventions to reduce malnutrition. These findings may inform public health policies to mitigate malnutrition among children in Malawi’s urban communities.

Aims In Malawi, there are three Consultant psychiatrists for a population of approximately 20 million people. We cannot rely solely on specialists to provide mental health care. We produced the Malawi Quick Guide to Mental Health (the Guide) to improve the psychiatric health-care resources available to frontline mental health workers in Malawi, thus improving service provision to patients. We aimed to evaluate its impact on the frontline non-specialists who provide most mental health care in Malawi. Methods In collaboration with the Malawi Ministry of Health, the University of Malawi, St John of God Malawi, and a Malawian user group, a group of psychiatrists with experience working in Malawi co-produced the Malawi Quick Guide to Mental Health. It provides practical information for assessing and managing mental disorders in Malawi. We distributed the Guide to over 400 health centres in Malawi. Next, we converted the Guide into a freely available phone app in both Android and Apple stores. To study its impact, we baseline surveyed frontline mental health professionals regarding their access to basic psychiatry guidelines and information in clinics, as well as their confidence in delivering mental health care. We repeated this survey six months after the distribution of the printed Guide and six months after the app launch. Results Baseline survey: 20 health-care professionals representing regions throughout Malawi responded. 70% of respondents were between 25–40 years old and 45% were female. All respondents either agreed or strongly agreed that they needed more support caring for mentally unwell patients. 15% had no access to any resources whatsoever to guide their care. Printed guide survey: 95% agreed or strongly agreed that having a printed copy of the Guide increased their confidence in caring for patients. Information resource accessibility, availability and usage in mental health clinics had improved from baseline. The respondents found the Guide helped their day-to-day practice, with 95% rating it either extremely helpful or very helpful. 95% either agreed or strongly agreed that it had improved the care they provided their patients. App survey: 66% of respondents prefer using the app over the textbook version. All agreed that the app made them more confident in caring for their patients and that their care had improved because of the app. They were all likely to recommend it to a colleague. It has now been downloaded almost 1000 times. Conclusion A free, co-produced mental health book and phone app have helped to address the issue of limited access to basic psychiatry guidelines and information in clinics in Malawi. This has improved clinicians’ confidence and their perceived patient care.

Objectives: This study aimed to investigate the changing SARS-CoV-2 seroprevalence and associated health and sociodemographic factors in Malawi between February 2021 and April 2022. Methods: In total, four 3-monthly serosurveys were conducted within a longitudinal population-based cohort in rural Karonga District and urban Lilongwe, testing for SARS-CoV-2 S1 immunoglobulin (Ig)G antibodies using an enzyme-linked immunosorbent assay. Population seroprevalence was estimated in all and unvaccinated participants. Bayesian mixed-effects logistic models estimated the odds of seropositivity in the first survey, and of seroconversion between surveys, adjusting for age, sex, occupation, location, and assay sensitivity/specificity. Results: Of the 2005 participants (Karonga, n = 1005; Lilongwe, n = 1000), 55.8% were female and median age was 22.7 years. Between Surveys (SVY) 1 and 4, population-weighted SARS-CoV-2 seroprevalence increased from 26.3% to 89.2% and 46.4% to 93.9% in Karonga and Lilongwe, respectively. At SVY4, seroprevalence did not differ by COVID-19 vaccination status in adults, except for those aged 30+ years in Karonga (unvaccinated: 87.4%, 95% credible interval 79.3-93.0%; two doses: 98.1%, 94.8-99.5%). Location and age were associated with seroconversion risk. Individuals with hybrid immunity had higher SARS-CoV-2 seropositivity and antibody titers, than those infected. Conclusion: High SARS-CoV-2 seroprevalence combined with low morbidity and mortality indicate that universal vaccination is unnecessary at this stage of the pandemic, supporting change in national policy to target at-risk groups.

Intervertebral disc degeneration and pain are associated with the nucleotide-binding domain, leucine-rich repeat, and pyrin domain-containing 3 (NLRP3) inflammasome activation and the processing of interleukin-1 beta (IL-1β). Activation of thehm inflammasome is triggered by Toll-like receptor stimulation and requires the cofactor receptor cluster of differentiation 14 (CD14). Short Link N (sLN), a peptide derived from link protein, has been shown to modulate inflammation and pain in discs in vitro and in vivo; however, the underlying mechanisms remain elusive. This study aims to assess whether sLN modulates IL-1β and inflammasome activity through interaction with CD14. Disc cells treated with lipopolysaccharides (LPS) with or without sLN were used to assess changes in Caspase-1, IL-1β, and phosphorylated nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB). Peptide docking of sLN to CD14 and immunoprecipitation were performed to determine their interaction. The results indicated that sLN inhibited LPS-induced NFκB and Caspase-1 activation, reducing IL-1β maturation and secretion in disc cells. A significant decrease in inflammasome markers was observed with sLN treatment. Immunoprecipitation studies revealed a direct interaction between sLN and the LPS-binding pocket of CD14. Our results suggest that sLN could be a potential therapeutic agent for discogenic pain by mitigating IL-1β and inflammasome activity within discs.

Applying cold to a bone injury can aid healing, though its mechanisms are complex. This study investigates how cold therapy impacts bone repair to optimize healing. Cold was applied to a rodent bone model, with the physiological responses analyzed. Vasoconstriction was mediated by an increase in the transient receptor protein channels (TRPs), transient receptor potential ankyrin 1 (TRPA1; p = 0.012), and transient receptor potential melastatin 8 (TRPM8; p < 0.001), within cortical defects, enhancing the sensory response and blood flow regulation. Cold exposure also elevated hypoxia (p < 0.01) and vascular endothelial growth factor expression (VEGF; p < 0.001), promoting angiogenesis, vital for bone regeneration. The increased expression of osteogenic proteins peroxisome proliferator-activated receptor gamma coactivator (PGC-1α; p = 0.039) and RNA-binding motif protein 3 (RBM3; p < 0.008) suggests that the reparative processes have been stimulated. Enhanced osteoblast differentiation and the presence of alkaline phosphatase (ALP) at day 5 (three-fold, p = 0.021) and 10 (two-fold, p < 0.001) were observed, along with increased osteocalcin (OCN) at day 10 (two-fold, p = 0.019), indicating the presence of mature osteoblasts capable of mineralization. These findings highlight cold therapy’s multifaceted effects on bone repair, offering insights for therapeutic strategies.

Introduction Monitoring the SARS-CoV-2 pandemic in low-resource countries such as Malawi requires cost-effective surveillance strategies. This study explored the potential utility of phone-based syndromic surveillance in terms of its reach, monitoring trends in reported SARS-CoV-2-like/influenza-like symptoms (CLS/ILS), SARS-CoV-2 testing and mortality.Methods Mobile phone-based interviews were conducted between 1 July 2020 and 30 April 2022, using a structured questionnaire. Randomly digital dialled numbers were used to reach individuals aged ≥18 years who spoke Chichewa or English. Verbal consent was obtained, and trained research assistants with clinical and nursing backgrounds collected information on age, sex, region of residence, reported CLS/ILS in the preceding 2 weeks, SARS-CoV-2 testing and history of household illness and death. Data were captured on tablets using the Open Data Kit database. We performed a descriptive analysis and presented the frequencies and proportions with graphical representations over time.Findings Among 356 525 active phone numbers, 138 751 (38.9%) answered calls, of which 104 360 (75.2%) were eligible, 101 617 (97.4%) consented to participate, and 100 160 (98.6%) completed the interview. Most survey respondents were aged 25–54 years (72.7%) and male (65.1%). The regional distribution of the respondents mirrored the regional population distribution, with 45% (44%) in the southern region, 41% (43%) in the central region and 14% (13%) in the northern region. The reported SARS-CoV2 positivity rate was 11.5% (107/934). Of the 7298 patients who reported CLS/ILS, 934 (12.8%) reported having undergone COVID-19 testing. Of the reported household deaths, 47.2% (982 individuals) experienced CLS/ILS 2 weeks before their death.Conclusion Telephonic surveillance indicated that the number of SARS-CoV-2 cases was at least twice as high as the number of confirmed cases in Malawi. Our findings also suggest a substantial under-reporting of SARS-CoV-2-related deaths. Telephonic surveillance has proven feasible in Malawi, achieving the ability to characterise SARS-CoV-2 morbidity and mortality trends in low-resource settings.

Background The completion of case-based surveillance forms was vital for case identification during COVID-19 surveillance in Malawi. Despite significant efforts, the resulting national data suffered from gaps and inconsistencies which affected its optimal usability. The objectives of this study were to investigate the processes of collecting and reporting COVID-19 data, to explore health workers’ perceptions and understanding of the collection tools and processes, and to identify factors contributing to data quality. Methods A total of 75 healthcare professionals directly involved in COVID-19 data collection from the Malawi Ministry of Health in Lilongwe and Blantyre participated in Focus Group Discussions and In-Depth Interviews. We collected participants’ views on the effectiveness of surveillance forms in collecting the intended data, as well as on the data collection processes and training needs. We used MAXQDA for thematic and document analysis. Results Form design significantly influenced data quality and, together with challenges in applying case definitions, formed 44% of all issues raised. Concerns regarding processes used in data collection and training gaps comprised 49% of all the issues raised. Language issues (2%) and privacy, ethical, and cultural considerations (4%), although mentioned less frequently, offered compelling evidence for further review. Conclusions Our study highlights the integral connection between data quality and the design and utilization of data collection forms. While the forms were deemed to contain the most relevant fields, deficiencies in format, order of fields, and the absence of an addendum with guidelines, resulted in large gaps and errors. Form design needs to be reviewed so that it appropriately fits into the overall processes and systems that capture surveillance data. This study is the first of its kind in Malawi, offering an in-depth view of the perceptions and experiences of health professionals involved in disease surveillance on the tools and processes they use.

Forests are important ecosystems offering extensive material and immaterial benefits to people and the environment. If not well monitored and sustainably managed, forest resource use can lead to degradation, which has global environmental and socio-economic implications. There is currently limited information on the factors that lead to forest use in the Cryptosepalum forests of Zambia, and how these factors potentially influence forest integrity. This study aimed at establishing the socio-economic aspects that determine resource utilisation and forest loss in the Cryptosepalum forest of Manyinga and Zambezi Districts of North-western Zambia. Using a semi-structured questionnaire 207 randomly selected households were interviewed in 7 villages surrounding the Cryptosepalum forest (4 in Manyinga and 3 in Zambezi district). Additionally, three focus Group Discussions were conducted to triangulate interview data. Descriptive statistics, Pearson's Chi-square test of independence and binary logistic regression were used to analyse the data. The study established 14 forest products used by local communities in the study sites. Socio-economic factors, namely; gender, level of education, household size, wealth, and residence status significantly influenced use of 9 of the 14 forest products. Further, significant relationships (p
