Pulmonary manifestations, treatments and outcomes of IgG4-related disease-a systematic literature review.

Immunoglobulin G4-related disease (IgG4-RD) is a multisystem fibroinflammatory condition. A consistent feature of many cases is pulmonary infiltrates, or respiratory failure. This systematic literature review aims to summarise the pulmonary manifestations of IgG4-RD, including clinical outcomes and treatment. This review was registered on PROSPERO (CRD42023416410). Medline, Embase and Cochrane databases were searched for articles discussing IgG4-RD syndrome. Information was extracted on demographics, type and prevalence of pulmonary manifestations, treatment and clinical outcomes. Initially, after deduplication, 3123 articles were retrieved with 18 ultimately included. A pooled total of 724 patients with IgG4-RD were included, 68.6% male, mean age 59.4 years (SD 5.8) at disease onset. The most frequently described pulmonary manifestation was mediastinal lymphadenopathy (n = 186, 48.8%), followed by pulmonary nodules (n = 151, 39.6%) and broncho-vascular thickening (n = 85, 22.3%). Where treatment was reported, the majority of patients received glucocorticoids (n = 211, 93.4%). Other immunosuppressive therapy included cyclophosphamide (n = 31), azathioprine (n = 18), with mycophenolate mofetil (n = 6), rituximab (n = 6), methotrexate (n = 5) and other unspecified immunomodulators (50). Clinical outcomes were reported in 263 patients, where 196 patients had remission of their disease, 20 had relapse, 35 had stable disease, four had progression and eight patients died from complications of IgG4-RD. This systematic review summarises pulmonary manifestations, treatments and outcomes in patients with IgG4-RD. Pulmonary involvement in IgG4-RD is relatively common, leading to high levels of morbidity and mortality. Glucocorticoids remain the mainstay of treatment, but further work is required to explore the management of patients with pulmonary manifestations in association with IgG4-RD.

Influence of medical-social and socio-economic factors on infant mortality rate in the Republic of Ingushetia

BACKGROUND: The infant mortality rate, as one of the indicators of the health and quality of life of the population, is an important factor that determines the country’s healthcare priorities. Despite the steadily decreasing infant mortality rates in the Russian Federation, the value of this indicator varies by region; thus, studying the factors influencing its value is relevant. If the leading medical, social, and socioeconomic factors that influence the level of infant mortality could be determined using data from a representative region (Republic of Ingushetia), the main directions for organizing measures aimed at reducing mortality among children in the first year of life will be identified. AIM: To determine the main medical, social and socio-economic factors that influence the infant mortality rate in the Republic of Ingushetia. MATERIALS AND METHODS: An observational single-center retrospective study was performed to examine the influence of medical, social, and socioeconomic factors on the mortality rate of children aged 1 year in the Republic of Ingushetia. The obtained data were compared with similar indicators for the Russian Federation as a whole and the North Caucasus Federal District. RESULTS: During the study period (2011–2019), significant changes were observed in infant mortality rates in the Republic of Ingushetia: infant mortality has decreased because of the age components, leading to the normal ratio of neonatal and post neonatal mortality. Rates of infant mortality from certain conditions arising in the perinatal period, congenital anomalies, and nervous system and circulatory system diseases have significantly decreased. The proportion of women admitted under the supervision of antenatal clinics in the early pregnancy (up to 12 weeks) has increased, the incidence of morbidity among pregnant women has decreased, and the proportion of normal births has been increasing. Although many medical organizations have employed a sufficient number of medical personnel, the coverage for biochemical screening has decreased, detection of malformations and biochemical abnormalities during prenatal diagnostics was low, medical personnel have low qualifications, and the shortage of obstetric and pediatric beds and pathology beds for newborns and premature infants was significant. A statistically significant dependence of the frequency of deaths of children aged 1 year on socioeconomic indicators−unemployment level, monetary income of the population, and housing conditions−was revealed. CONCLUSION: The main medical, social, and socioeconomic factors that influence infant mortality were analyzed using data from the Republic of Ingushetia. Positive and negative trends in the current state of the healthcare system of this republic have been identified.

Introduction. Ensuring road safety is one of the foremost tasks in any country with vehicular traffic. Despite significant efforts made to improve road safety in Ukraine and globally, the issue of traffic accidents is still relevant. Problem statement. Given the relatively high level of mortality due to accidents, Ukraine needs to ensure highly qualified management of road safety, which requires an integrated approach and consideration of various aspects, including legislation, infrastructure, vehicles and road user’s behavior. Purpose. Ensuring road safety, reducing the severity of the consequences of traffic accidents and providing comfortable travel conditions for road users. Materials and methods. Current legislative acts and regulatory documents regarding the identification of places (areas) of concentration of traffic accidents, as well as statistical information on the number of such places (areas) were analyzed. Results. It has been established that the implementation of a new criterion for identifying the places (areas) of the concentration of traffic accidents is justified and indicates a systematic approach to road safety management.

Placental Drug Delivery to Treat Pre-Eclampsia and Fetal Growth Restriction.

Pre-eclampsia and fetal growth restriction (FGR) continue to cause unacceptably high levels of morbidity and mortality, despite significant pharmaceutical and technological advances in other disease areas. The recent pandemic has also impacted obstetric care, as COVID-19 infection increases the risk of poor pregnancy outcomes. This review explores the reasons why it lacks effective drug treatments for the placental dysfunction that underlies many common obstetric conditions and describes how nanomedicines and targeted drug delivery approaches may provide the solution to the current drug drought. The ever-increasing range of biocompatible nanoparticle formulations available is now making it possible to selectively deliver drugs to uterine and placental tissues and dramatically limit fetal drug transfer. Formulations that are refractory to placental uptake offer the possibility of retaining drugs within the maternal circulation, allowing pregnant individuals to take medicines previously considered too harmful to the developing baby. Liposomes, ionizable lipid nanoparticles, polymeric nanoparticles, and adenoviral vectors have all been used to create efficacious drug delivery systems for use in pregnancy, although each approach offers distinct advantages and limitations. It is imperative that recent advances continue to be built upon and that there is an overdue investment of intellectual and financial capital in this field.

Association between Child Mortality and Healthcare Facility Level Factors: Evidence from Nationally Representative Survey

Child mortality is an important indicator of child health and overall national development. Under-five mortality is unacceptably high in Low- and Middle-Income Countries (LMICs) including Bangladesh. Increased availability and access to the healthcare services can play a significant role to reduce under-five mortality. The aim of this study was to explore the associations of several forms of child mortality with health facility level factors. Data were extracted from the 2017-18 Bangladesh Demographic and Health Survey data and 2017 Bangladesh Health Facility Survey data. Three outcome variables were considered: neonatal mortality, infant mortality, and under-five mortality in this study. Health facility level factors were considered as major explanatory variables. They were the availability of the child healthcare services at the nearest healthcare facility, readiness of the nearest healthcare facility to provide child healthcare services and the average distance of the nearest healthcare facility providing child healthcare services. Multilevel mixed-effect logistic regression model was used to determine the associations between the outcome variables and explanatory variables adjusted for covariates. We reported under-five, infant and neonatal mortality were 40, 37, and 30 per 1000 live births, respectively. The likelihood of neonatal and infant mortality was found to be declined for one-unit increase on the availability and readiness of the mothers’ homes nearest healthcare facilities to provide child healthcare services. On contrary, for every kilometre increased distance between mothers’ homes and their nearest healthcare facility was found to be associated with increased in the likelihoods of neonatal, infant and under-five mortality. The availability of health facilities providing child healthcare services close to residence and their improved management, infrastructure, and readiness to provide child healthcare services play a significant role in reducing under-five mortality in Bangladesh. Policies and programs should prioritize to increase the availability and accessibility of health facilities that provide child healthcare services.

Endotyping in ARDS: one step forward in precision medicine

BackgroundThe Berlin definition of acute respiratory distress syndrome (ARDS) includes only clinical characteristics. Understanding unique patient pathobiology may allow personalized treatment. We aimed to define and describe ARDS phenotypes/endotypes combining clinical and pathophysiologic parameters from a Canadian ARDS cohort.MethodsA cohort of adult ARDS patients from multiple sites in Calgary, Canada, had plasma cytokine levels and clinical parameters measured in the first 24 h of ICU admission. We used a latent class model (LCM) to group the patients into several ARDS subgroups and identified the features differentiating those subgroups. We then discuss the subgroup effect on 30 day mortality.ResultsThe LCM suggested three subgroups (n1 = 64, n2 = 86, and n3 = 30), and 23 out of 69 features made these subgroups distinct. The top five discriminating features were IL-8, IL-6, IL-10, TNF-a, and serum lactate. Mortality distinctively varied between subgroups. Individual clinical characteristics within the subgroup associated with mortality included mean PaO2/FiO2 ratio, pneumonia, platelet count, and bicarbonate negatively associated with mortality, while lactate, creatinine, shock, chronic kidney disease, vasopressor/ionotropic use, low GCS at admission, and sepsis were positively associated. IL-8 and Apache II were individual markers strongly associated with mortality (Area Under the Curve = 0.84).PerspectiveARDS subgrouping using biomarkers and clinical characteristics is useful for categorizing a heterogeneous condition into several homogenous patient groups. This study found three ARDS subgroups using LCM; each subgroup has a different level of mortality. This model may also apply to developing further trial design, prognostication, and treatment selection.

Association of dietary selenium intake and all-cause mortality of Parkinson’s disease and its interaction with blood cadmium level: a retrospective cohort study

BackgroundParkinson’s disease (PD) is a slowly progressive neurodegenerating disease that may eventually lead to disabling condition and pose a threat to the health of aging populations. This study aimed to explore the association of two potential risk factors, selenium and cadmium, with the prognosis of Parkinson’s disease as well as their interaction effect.MethodsData were obtained from the National Health and Nutrition Examination Survey (NHANES) 2005–2006 to 2015–2016 and National Death Index (NDI). Participants were classified as Parkinson’s patients by self-reported anti-Parkinson medications usage. Cox regression models and restricted cubic spline models were applied to evaluate the association between PD mortality and selenium intake level as well as blood cadmium level. Subgroup analysis was also conducted to explore the interaction between them.ResultsA total of 184 individuals were included. In full adjusted cox regression model (adjusted for age, gender, race, hypertension, pesticide exposure, smoking status and caffeine intake), compared with participants with low selenium intake, those with normal selenium intake level were significantly associated with less risk of death (95%CI: 0.18–0.76, P = 0.005) while no significant association was found between low selenium intake group and high selenium group (95%CI: 0.16–1.20, P = 0.112). Restricted cubic spline model indicated a nonlinear relationship between selenium intake and PD mortality (P for nonlinearity = 0.050). The association between PD mortality and blood cadmium level was not significant (95%CI: 0.19–5.57, P = 0.112). However, the interaction term of selenium intake and blood cadmium showed significance in the cox model (P for interaction = 0.048). Subgroup analysis showed that the significant protective effect of selenium intake existed in populations with high blood cadmium but not in populations with low blood cadmium.ConclusionModerate increase of selenium intake had a protective effect on PD mortality especially in high blood cadmium populations.

Reducing childhood mortality extends mothers’ lives

During the twentieth century, childhood mortality was dramatically reduced globally, falling by more than 90% in the United States and much of Europe. Total fertility also fell, with the combined result that many parents who otherwise would have experienced the loss of a child were spared the trauma and negative health consequences that accompany such a loss. Here I use mathematical modeling to argue that the reduction in the frequency of child death that occurred in the twentieth century indirectly led to a substantial reduction in female mortality, resulting in an extension of female lifespan. I estimate that the reduction in maternal bereavement in the US during the twentieth century indirectly increased mean female lifespan after age 15 by approximately 1 year. I discuss implications for our understanding of the persistence of the sex gap in longevity and approaches to improving maternal health outcomes in countries that still face high levels of childhood mortality.

Short-term results after total hip arthroplasty using dual-mobility acetabular cup on geriatric patients with femoral neck fracture

The rate of femoral neck fractures (FNF) increases exponentially with age, meanwhile in geriatric patients they are associated with high levels of functional deficiency and mortality. Studies find that hip arthroplasty is a method of choice for treatment of displaced FNF. One option regarding the increased risk of postoperative dislocation in these patients is the dual-mobility acetabular cup (DMAC). The aim of our study is to assess the functional outcome, joint stability and complication rate after total hip arthroplasty (THA) using DMAC in geriatric patients with FNF. In the study were included 390 patients with a mean follow-up period of 31.2 months. No cases of dislocation or intraprosthetic dislocation were encountered. Displaced FNF can successfully be treated with THA using DMAC, as it provides excellent stability and function, as well as low risk of revision surgery.

Estimation of cause-specific mortality in Rakai, Uganda, using verbal autopsy 1999-2019

ABSTRACT Background There are scant data on the causes of adult deaths in sub-Saharan Africa. We estimated the level and trends in adult mortality, overall and by different causes, in rural Rakai, Uganda, by age, sex, and HIV status. Objectives To estimate and analyse adult cause-specific mortality trends in Rakai, Uganda. Methodology Mortality information by cause, age, sex, and HIV status was recorded in the Rakai Community Cohort study using verbal autopsy interviews, HIV serosurveys, and residency data. We estimated the average number of years lived in adulthood. Using demographic decomposition methods, we estimated the contribution of each cause of death to adult mortality based on the average number of years lived in adulthood. Results Between 1999 and 2019, 63082 adults (15–60 years) were censused, with 1670 deaths registered. Of these, 1656 (99.2%) had completed cause of death data from verbal autopsy. The crude adult death rate was 5.60 (95% confidence interval (CI): 5.33–5.87) per 1000 person-years of observation (pyo). The crude death rate decreased from 11.41 (95% CI: 10.61–12.28) to 3.27 (95% CI: 2.89–3.68) per 1000 pyo between 1999–2004 and 2015–2019. The average number of years lived in adulthood increased in people living with HIV and decreased in HIV-negative individuals between 2000 and 2019. Communicable diseases, primarily HIV and Malaria, had the biggest decreases, which improved the average number of years lived by approximately extra 12 years of life in females and 6 years in males. There were increases in deaths due to non-communicable diseases and external causes, which reduced the average number of years lived in adulthood by 2.0 years and 1.5 years in females and males, respectively. Conclusion There has been a significant decline in overall mortality from 1999 to 2019, with the greatest decline seen in people living with HIV since the availability of antiretroviral therapy in 2004. By 2020, the predominant causes of death among females were non-communicable diseases, with external causes of death dominating in males.

Ghrelin for Neuroprotection in Post–Cardiac Arrest Coma

Out-of-hospital cardiac arrest survival rates have markedly risen in the last decades, but neurological outcome only improved marginally. Despite research on more than 20 neuroprotective strategies involving patients in comas after cardiac arrest, none have demonstrated unequivocal evidence of efficacy; however, treatment with acyl-ghrelin has shown improved functional and histological brain recovery in experimental models of cardiac arrest and was safe in a wide variety of human study populations. To determine safety and potential efficacy of intravenous acyl-ghrelin to improve neurological outcome in patients in a coma after cardiac arrest. A phase 2, double-blind, placebo-controlled, multicenter, randomized clinical trial, Ghrelin Treatment of Comatose Patients After Cardiac Arrest: A Clinical Trial to Promote Cerebral Recovery (GRECO), was conducted between January 18, 2019, and October 17, 2022. Adult patients 18 years or older who were in a comatose state after cardiac arrest were assessed for eligibility; patients were from 3 intensive care units in the Netherlands. Expected death within 48 hours or unfeasibility of treatment initiation within 12 hours were exclusion criteria. Patients were randomized to receive intravenous acyl-ghrelin, 600 μg (intervention group), or placebo (control group) within 12 hours after cardiac arrest, continued for 7 days, twice daily, in addition to standard care. Primary outcome was the score on the Cerebral Performance Categories (CPC) scale at 6 months. Safety outcomes included any serious adverse events. Secondary outcomes were mortality and neuron-specific enolase (NSE) levels on days 1 and 3. A total of 783 adult patients in a coma after cardiac arrest were assessed for eligibility, and 160 patients (median [IQR] age, 68 [57-75] years; 120 male [75%]) were enrolled. A total of 81 patients (51%) were assigned to the intervention group, and 79 (49%) were assigned to the control group. The common odds ratio (OR) for any CPC improvement in the intervention group was 1.78 (95% CI, 0.98-3.22; P = .06). This was consistent over all CPC categories. Mean (SD) NSE levels on day 1 after cardiac arrest were significantly lower in the intervention group (34 [6] μg/L vs 56 [13] μg/L; P = .04) and on day 3 (28 [6] μg/L vs 52 [14] μg/L; P = .08). Serious adverse events were comparable in incidence and type between the groups. Mortality was 37% (30 of 81) in the intervention group vs 51% (40 of 79) in the control group (absolute risk reduction, 14%; 95% CI, -2% to 29%; P = .08). In patients in a coma after cardiac arrest, intravenous treatment with acyl-ghrelin was safe and potentially effective to improve neurological outcome. Phase 3 trials are needed for conclusive evidence. Clinicaltrialsregister.eu: EUCTR2018-000005-23-NL.

Virulence phenotypes differ between toxigenic Vibrio parahaemolyticus isolated from western coasts of Europe

Vibrio parahaemolyticus is the leading bacterial cause of gastroenteritis associated with seafood consumption worldwide. Not all members of the species are thought to be pathogenic, thus identification of virulent organisms is essential to protect public health and the seafood industry. Correlations of human disease and known genetic markers (e.g. thermostable direct hemolysin (TDH), TDH-related hemolysin (TRH)) appear complex. Some isolates recovered from patients lack these factors, while their presence has become increasingly noted in isolates recovered from the environment. Here, we used whole-genome sequencing in combination with mammalian and insect models of infection to assess the pathogenic potential of V. parahaemolyticus isolated from European Atlantic shellfish production areas. We found environmental V. parahaemolyticus isolates harboured multiple virulence-associated genes, including TDH and/or TRH. However, carriage of these factors did not necessarily reflect virulence in the mammalian intestine, as an isolate containing TDH and the genes coding for a type 3 secretion system (T3SS) 2α virulence determinant, appeared avirulent. Moreover, environmental V. parahaemolyticus lacking TDH or TRH could be assigned to groups causing low and high levels of mortality in insect larvae, with experiments using defined bacterial mutants showing that a functional T3SS1 contributed to larval death. When taken together, our findings highlight the genetic diversity of V. parahaemolyticus isolates found in the environment, their potential to cause disease and the need for a more systematic evaluation of virulence in diverse V. parahaemolyticus to allow better genetic markers.

Maternal health in cities: analysis of institutional maternal mortality and health system bottlenecks in Kampala City Uganda, 2016-2021

Background Recent estimates have shown a stagnation in maternal mortality reduction globally. Levels and trends in maternal mortality in urban settings in Africa are of interest due to health system challenges posed by rapid urbanisation. Given the high percentage of births occurring in city health facilities, tracking the institutional maternal mortality ratio (IMMR) can reveal key performance issues. We described the trends in IMMR between 2016 and 2021, and the causes and characteristics of maternal deaths in Kampala, Uganda. Methods This retrospective study utilised routine data from all facilities in Kampala that provided childbirth services from 2016 to 2021. Three key variables were used: number of deliveries, live births, and maternal deaths. Additionally, from medical records in three purposively selected hospitals, we extracted information on characteristics of women recorded as maternal deaths and their causes for the period 2016-2021 from death notification and review forms. We conducted descriptive analysis and assessed time trends in IMMR. Results For the six-year period, the Kampala-level IMMR was 189/100,000 deliveries (194/100,000 livebirths). The IMMR declined from 213 (2016) to 109/100,000 deliveries in 2019 (p=0.04) and then increased to 258 in 2021 (p=0.12). A review of 358 maternal death records showed that 65% of deaths were women referred from other health facilities, and 47% lived in the surrounding district (Wakiso). Obstetric haemorrhage (44%) and hypertensive disorders in pregnancy (28%) were the most commonly recorded causes of death. Health system factors such as lack of blood and other supplies contributed to 65% of the deaths reviewed. Conclusions IMMR in Kampala increased from 2019-2021. Health infrastructure changes and maternal health initiatives potentially accounted for the observed trend by affecting data quality. Referral and facility readiness were underlying reasons for maternal deaths. Addressing bottlenecks in emergency referral processes may contribute to mortality reduction. Further research should determine the relative contribution of key influences on mortality levels and examine the dynamics between women’s care-seeking pathways and service delivery arrangements for emergency obstetric care in urban settings.

Factors contributing to high performance of sows in free farrowing systems

BackgroundPressure to abolish farrowing crates is increasing, and producers are faced with decisions about which alternative system to adopt. For sow welfare, well designed free farrowing systems without close confinement are considered optimal but producers have concerns about increased piglet mortality, particularly crushing by the sow. Reporting accurate performance figures from commercial farms newly operating such systems could inform the transition process. This study investigated performance on three commercial farms operating four different zero-confinement systems, three of which were newly installed. A total of 3212 litters from 2920 sows were followed from farrowing to weaning over a three-year period with key performance indicators (KPIs) recorded. Mixed Models (LMMs, GLMMs) determined the influence of different factors (e.g. farrowing system, sow parity, management aspects) and litter characteristics on performance, including levels and causes of piglet mortality.ResultsPiglet mortality was significantly influenced by farm/system. Live-born mortality ranged from 10.3 to 20.6% with stillbirths ranging from 2.5 to 5.9%. A larger litter size and higher parity resulted in higher levels of mortality regardless of system. In all systems, crushing was the main cause of piglet mortality (59%), but 31% of sows did not crush any piglets, whilst 26% crushed only one piglet and the remaining sows (43%) crushed two or more piglets. System significantly influenced crushing as a percentage of all deaths, with the system with the smallest spatial footprint (m2) compared to the other systems, recording the highest levels of crushing. Time from the start of the study influenced mortality, with significant reductions in crushing mortality (by ~ 4%) over the course of the three-year study. There was a highly significant effect of length of time (days) between moving sows into the farrowing accommodation and sows farrowing on piglet mortality (P < 0.001). The less time between sows moving in and farrowing, the higher the levels of piglet mortality, with ~ 3% increase in total mortality every five days. System effects were highly significant after adjusting for parity, litter size, and days pre-farrowing.ConclusionThese results from commercial farms demonstrate that even sows that have not been specifically selected for free farrowing are able, in many cases, to perform well in these zero-confinement systems, but that a period of adaptation is to be expected for overall farm performance. There are performance differences between the farms/systems which can be attributed to individual farm/system characteristics (e.g. pen design and management, staff expertise, pig genotypes, etc.). Higher parity sows and those producing very large litters provide a greater challenge to piglet mortality in these free farrowing systems (just as they do in crate systems). Management significantly influences performance, and ensuring sows have plenty of time to acclimatise between moving in to farrowing accommodation and giving birth is a critical aspect of improving piglet survival.

Trends in prevalence, mortality, and risk factors of dementia among the oldest-old adults in the United States: the role of the obesity epidemic.

The oldest-old population, those aged ≥ 80years, is the fastest-growing group in the United States (US), grappling with an increasingly heavy burden of dementia. We aimed to dissect the trends in dementia prevalence, mortality, and risk factors, and predict future levels among this demographic. Leveraging data from the Global Burden of Disease Study 2019, we examined the trends in dementia prevalence, mortality, and risk factors (with a particular focus on body mass index, BMI) for US oldest-old adults. Through decomposition analysis, we identified key population-level contributors to these trends. Predictive modeling was employed to estimate future prevalence and mortality levels over the next decade. Between 1990 and 2019, the number of dementia cases and deaths among the oldest-old in the US increased by approximately 1.37 million and 60,000 respectively. The population growth and aging were highlighted as the primary drivers of this increase. High BMI emerged as a growing risk factor. Females showed a disproportionately higher dementia burden, characterized by a unique risk factor profile, including BMI. Predictions for 2030 anticipate nearly 4 million dementia cases and 160,000 related deaths, with a marked increase in prevalence and mortality anticipated among those aged 80-89. The past 30years have witnessed a notable rise in both the prevalence and mortality of dementia among the oldest-old in the US, accompanied by a significant shift in risk factors, with obesity taking a forefront position. Targeted age and sex-specific public health strategies that address obesity control are needed to mitigate the dementia burden effectively.

NT-proBNP point-of-care testing for predicting mortality in end-stage renal disease: A survival analysis

This study examines the predictive value of elevated N-terminal-pro brain natriuretic peptide (NT-pro BNP) levels for mortality among patients with end-stage renal disease (ESRD). Data from 768 ESRD patients, excluding those with cancer or lost follow-up, were analyzed using Kaplan–Meier curves and Cox proportional hazards models over three years. Results indicated that patients with very high NT-pro BNP levels had shorter average survival times and a significantly higher risk of mortality (hazard ratio 1.43). Advanced age, ICU admission, and comorbidities like cerebrovascular diseases and chronic obstructive pulmonary disease also contributed to increased mortality risks. Thus, elevated NT-pro BNP is an independent risk factor for mortality in ESRD patients.

Infectious bronchitis virus: an overview of the "chicken coronavirus".

Infectious bronchitis virus (IBV) is a highly contagious avian Gammacoronavirus that affects mainly chickens (Gallus gallus) but can circulate in other avian species. IBV constitutes a significant threat to the poultry industry, causing reduced egg yield, growth and mortality levels that can vary in impact. The virus can be transmitted horizontally by inhalation or direct/indirect contact with infected birds or contaminated fomites, vehicles, farm personnel and litter (Figure 1). The error-prone viral polymerase and recombination mechanisms mean diverse viral population results, with multiple genotypes, serotypes, pathotypes and protectotypes. This significantly complicates control and mitigation strategies based on vigilance in biosecurity and the deployment of vaccination.

Multicentric investigations of the role in the disease severity of accelerated phospholipid changes in COVID-19 patient airway

ContextThe changes in host membrane phospholipids are crucial in airway infection pathogenesis. Phospholipase A2 hydrolyzes host cell membranes, producing lyso-phospholipids and free fatty acids, including arachidonic acid (AA), which contributes significantly to lung inflammation. AimFollow these changes and their evolution from day 1, day 3 to day 7 in airway aspirates of 89 patients with COVID-19-associated acute respiratory distress syndrome and examine whether they correlate with the severity of the disease. The patients were recruited in three French intensive care units. The analysis was conducted from admission to the intensive care unit until the end of the first week of mechanical ventilation. ResultsIn the airway aspirates, we found significant increases in the levels of host cell phospholipids, including phosphatidyl-serine and phosphatidyl-ethanolamine, and their corresponding lyso-phospholipids. This was accompanied by increased levels of AA and its inflammatory metabolite prostaglandin E2 (PGE2). Additionally, enhanced levels of ceramides, sphingomyelin, and free cholesterol were observed in these aspirates. These lipids are known to be involved in cell death and/or apoptosis, whereas free cholesterol plays a role in virus entry and replication in host cells. However, there were no significant changes in the levels of dipalmitoyl-phosphatidylcholine, the major surfactant phospholipid. A correlation analysis revealed an association between mortality risk and levels of AA and PGE2, as well as host cell phospholipids. ConclusionOur findings indicate a correlation between heightened cellular phospholipid modifications and variations in AA and PGE2 with the severity of the disease in patients. Nevertheless, there is no indication of surfactant alteration in the initial phases of the illness.

Community Conversations: A Tool in Improving Health Outcomes and Reducing the Burden of Visceral Leishmaniasis (Kala-azar) in Isiolo County, Kenya

Visceral Leishmaniasis (Kala-azar) is a neglected tropical disease (NTD) caused by Leishmania species that affects human. Transmission is through the bite of Phlebotomus sandflies. Globally, WHO ranks Kala-azar as the second largest parasitic killer after Malaria. The disease poses a threat to more than a billion people on almost every continent. Approximately 90% of Kala-azar global burden is found in Africa. Major endemicity is documented in Eastern Africa (Kenya, South Sudan, Sudan, Ethiopia, and Somalia). Accurate burden of the disease in Kenya is unknown attributable to inadequate information on disease prevalence, diagnostic challenges, and spatial distribution. Additionally, morbidity and mortality levels from the disease in the Country are unknown ascribable to a low index of suspicion by healthcare workers, diagnostic challenges, and case management. An example of diagnostic challenges is a reported outbreak of ‘unknown disease’ akin to Kala-azar in Marsabit County in May 2023 where nine people were confirmed dead and over 80 hospitalized. This study aimed to analyze community’s prioritization of causes of Kalaazar as well as community awareness of disease prevention and control. Quantitative data were collected using Participatory Epidemiology methods in purposively selected study villages. Qualitative data were collected through semi-structured interviews. Study findings indicated that 97.2% of respondents had heard about Kala-azar. Despite the awareness, a broad gap between knowledge and practice of prevention and control strategies of the disease was evident. Kala-azar was associated with human behaviour like preferences for traditional and alternative treatment approaches (45.2%), evening outdoor practices before going to bed (99.6%), sleeping outdoors (60.1%), occasional bed nets use (69.2%), and availability of domestic animals and wild animals within house yards (54.6%). Cultural beliefs and practices were noted to play a key role in augmenting the disease burden, where most cases had burn scars from traditional healers’ therapeutic burns. As a consequence, they sought medical help after onset of complications, which ranged from increased severity to fatalities. Community engagement was minimal in prevention and control. In this participatory research, we propose behaviour change communication activities for the elimination of Kala-azar as a public health problem. This article serves as a base for future studies aimed at giving voice to communities while enhancing their understanding of causes of diseases, the possibility of enhanced early diagnostic techniques, and options for prevention, control, and surveillance which in turn is translated to action.
