Progression of Skin Ulcer Secondary to Calciphylaxis in a Patient With End-Stage Renal Disease (ESRD) on Hemodialysis and the Therapeutic Approach.

Calciphylaxis is a rare and severe medical condition characterized by the calcification of small blood vessels and soft tissues, leading to tissue damage, skin ulcers, and intense pain. It most commonly affects individuals with underlying health conditions such as kidney disease, particularly end-stage renal disease (ESRD), and is associated with high mortality rates. Understanding the diagnosis and management of calciphylaxis is crucial for improving patient outcomes. Diagnosing calciphylaxis can be challenging due to its rarity and overlapping symptoms with other skin conditions. Healthcare professionals typically use a combination of clinical evaluation and diagnostic tests to reach a conclusive diagnosis. The management of calciphylaxis is multifaceted and typically involves a collaborative effort between various healthcare specialists, including nephrologists, dermatologists, and wound care experts. The primary goals of treatment are to alleviate pain, promote wound healing, address underlying causes, and prevent further complications.

Comparison of Rifaximin Alone and With Quinolones in the Primary Prevention of Spontaneous Bacterial Peritonitis in Patients With Decompensated Chronic Liver Disease.

Background In cirrhotic patients with ascites, primary prevention of spontaneous bacterial peritonitis (SBP) is a key strategy to lower morbidity and death. Rifaximin and fluoroquinolone used alternately as main prophylaxis are as effective as reported. This study aimed to compare the frequency of occurrence of SBP in patients with decompensated chronic liver disease treated with rifaximin alone and in combination with fluoroquinolone. Methodology A total of 76 patients with hepatitis C virus-related decompensated chronic liver disease and ascites were divided into two groups based on matching age, sex, and Child-Pugh class. Group A (38 patients) received rifaximin 1,100 mg/day in two divided doses with daily fluoroquinolone 400 mg/day, whereas group B (38 patients) received rifaximin 1,100 mg/day alone as a two dosage. The patients were monitored for up to three months. The study's endpoints were SBP, hepatocellular carcinoma, compliance failure, death, or liver transplantation. Results In this comparative study involving 76 patients, the demographic and clinical characteristics were assessed across two treatment groups: rifaximin alone (n = 38) and rifaximin with fluoroquinolone (n = 38). The combination therapy demonstrated a statistically significant reduction in SBP compared to rifaximin alone. Additionally, the overall survival rate was higher in the combination group. These findings suggest potential benefits of the combined approach in managing hepatic encephalopathy-related complications. Conclusions When compared to rifaximin alone for primary SBP prophylaxis, the combination of rifaximin with fluoroquinolone exhibited greater effectiveness with the same safety profile.

Frequency of Pulmonary Hypertension and Its Associated Risk Factors in End-Stage Renal Disease (ESRD) Patients on Maintenance Hemodialysis.

Introduction Pulmonary hypertension (PH) is a recognized complication in patients with end-stage renal disease (ESRD undergoing maintenance hemodialysis (MHD). PH is commonly found in patients with chronic kidney disease (CKD) and ESRD. PH is associated with increased morbidity and mortality in patients with CKD. Methodology This cross-sectional study aimed to assess the prevalence of PH and its associated risk factors in MHD patients. A total of 220 ESRD patients on MHD patients at The Kidney Center, Karachi, Pakistan, aged 18-70 were included. Patients with chronic obstructive lung disease, valvular heart disease, and obstructive sleep apnea were excluded, as these conditions can be responsible for PH. PH was evaluated by echocardiography (ECHO), which was performed by a cardiologist. Results The mean age was 50.65 ± 14.4 years, with 131 (59.5%) males and 89 (40.5%) females. The average duration on hemodialysis was 5.3 ± 2.8 years. Hypertension (89.5%) and ischemic heart disease (24.1%) were prominent comorbidities. Hypertensive nephropathy (42.7%) was the leading cause of ESRD. Left ventricular hypertrophy was mild in most cases (85.5%), whereas regional wall motion abnormality (RWMA) was common (67.3%). The average pulmonary artery pressure was 35.2 ± 15.3 mmHg. Out of 220 patients, 109 patients (49.8%) of them had mild PH, nine patients (4.1%) had severe PH, and 72 patients (32.7%) had moderate PH. Associations between PH and various factors were examined. RWMA, left ventricular hypertrophy, and left ventricular ejection fraction were significantly associated with PH (p < 0.001). Serum calcium and albumin levels were also associated with PH severity (p < 0.05). Other demographic and laboratory parameters did not show a significant association. Conclusion This study highlights the prevalence of PH in MHD patients and identifies associated risk factors. Understanding these associations can aid in better managing PH in ESRD patients.

Bridging the Gaps: The Transformative Effect of Coronavirus Disease 2019 (COVID-19) on Preventive Measures Among Medical and Health Sciences College Students in Madinah, Saudi Arabia.

Background The global impact of coronavirus disease 2019 (COVID-19) has disrupted the activities of medical and health profession education institutions. This study aimed to determine the impact of COVID-19 on medical and health profession education students' knowledge, attitudes, and practices toward preventive measures and their commitment to precautionary measures before, during, and after the pandemic. Materials and methods A cross-sectional study was carried out from January to March 2023 using an online, structured, validated questionnaire survey to gather information from medical and health sciences students from three universities, encompassing five colleges in Madinah, Saudi Arabia. The minimum required sample size was estimated using the Epi Info software as 380. The data was analyzed using IBM SPSS Statistics for Windows, Version 20.0 (Released 2011; IBM Corp., Armonk, New York, United States). Statistical tests including Student's t-test, chi-squared test, and analysis of variance (ANOVA) test were applied. Results The findings revealed that personal experiences with COVID-19 infection had a significant impact on students' attitudes and commitment to preventive measures (p<0.05). Among the participants, 172 students (45%) reported having contracted COVID-19. Students with clinical exposure showed a higher level of understanding and adherence to preventive measures (248 students, 68%), compared to pre-clinical students (198 students, 52%) (p<0.05). Positive attitudes were observed toward practices such as sneezing etiquette (289 students, 76%) and flu vaccination (314 students, 83%) (p<0.05). However, negative attitudes were observed toward mask-wearing (155 students, 41%) and social distancing (144 students, 38%), particularly among male students (p<0.05). Conclusion The study provided valuable insights into the impact of the COVID-19 pandemic on medical and health sciences students' knowledge, attitudes, and practices toward preventive measures and the importance of introducing COVID-19 prevention measures in the pre-clinical phase as well as mental health support to promote positive attitudes and enhance adherence to preventive measures.

The Fixed Dose Combination of Sofosbuvir and Velpatasvir is Safe and Effective in Patients of Chronic Hepatitis C With End-stage Renal Disease.

Background: The burden of hepatitis C virus (HCV) in India is alarming, with a major share of this virus being witnessed in patients with end-stage renal disease (ESRD). A pan-genotypic combination of sofosbuvir and velpatasvir is found to be safe, effective, and economical in resource-constraint countries such as ours. However, there are scanty data on the efficacy and safety of sofosbuvir and velpatasvir combination in patients with ESRD. Hence, we performed this study to evaluate the safety and efficacy of the combination of sofosbuvir and velpatasvir in patients of chronic hepatitis C (CHC) with ESRD. Methods: This is an observational study comprising of 40 CHC patients with ESRD on maintenance hemodialysis. All patients were treated with a fixed-dose combination of sofosbuvir and velpatasvir for 12 weeks in case of non-cirrhotic or compensated cirrhosis and 24 weeks in case of decompensated cirrhosis. The efficacy was assessed by sustained virological response defined by negative HCV RNA at 12 weeks (sustained virological response [SVR] 12) post treatment, and safety was assessed by recording any side-effects of all patients. Results: Out of the 40 patients enrolled in our study, majority were non-cirrhotic (77%), and all were treatment-naive. The mean age was 49.87 ± 12.13 years, and 80% patients were male. The mean baseline HCV RNA was 2.61 ± 7.83 × 106 IU/ml. All the 40 patients (100%) achieved undetectable HCV RNA at the end of treatment; however, 39 patients (97.5%) achieved SVR 12. There was no significant deterioration of estimated glomerular filtration rate (eGFR) after completion of antiviral therapy as compared to the baseline eGFR (13.27 ± 10.32 vs13.54 ± 11.38, P = 0.54). None of the patients reported any serious adverse effects during treatment. Conclusion: The fixed-dose combination of sofosbuvir and velpatasvir is effective and has showed excellent safety profile in patients of CHC with ESRD.

Impact of infectious density-induced additional screening and treatment saturation on COVID-19: Modeling and cost-effective optimal control.

This study introduces a novel SI2HR model, where "I2" denotes two infectious classes representing asymptomatic and symptomatic infections, aiming to investigate and analyze the cost-effective optimal control measures for managing COVID-19. The model incorporates a novel concept of infectious density-induced additional screening (IDIAS) and accounts for treatment saturation. Furthermore, the model considers the possibility of reinfection and the loss of immunity in individuals who have previously recovered. To validate and calibrate the proposed model, real data from November-December 2022 in Hong Kong are utilized. The estimated parameters obtained from this calibration process are valuable for prediction purposes and facilitate further numerical simulations. An analysis of the model reveals that delays in screening, treatment, and quarantine contribute to an increase in the basic reproduction number R0, indicating a tendency towards endemicity. In particular, from the elasticity of R0, we deduce that normalized sensitivity indices of baseline screening rate (θ), quarantine rates (γ, αs), and treatment rate (α) are negative, which shows that delaying any of these may cause huge surge in R0, ultimately increases the disease burden. Further, by the contour plots, we note the two-parameter behavior of the infectives (both symptomatic and asymptomatic). Expanding upon the model analysis, an optimal control problem (OCP) is formulated, incorporating three control measures: precautionary interventions, boosted IDIAS, and boosted treatment. The Pontryagin's maximum principle and the forward-backward sweep method are employed to solve the OCP. The numerical simulations highlight that enhanced screening and treatment, coupled with preventive interventions, can effectively contribute to sustainable disease control. However, the cost-effectiveness analysis (CEA) conducted in this study suggests that boosting IDIAS alone is the most economically efficient and cost-effective approach compared to other strategies. The CEA results provide valuable insights into identifying specific strategies based on their cost-efficacy ranking, which can be implemented to maximize impact while minimizing costs. Overall, this research offers significant insights for policymakers and healthcare professionals, providing a framework to optimize control efforts for COVID-19 or similar epidemics in the future.

MucoRice-CTB line 19A, a new marker-free transgenic rice-based cholera vaccine produced in an LED-based hydroponic system.

We previously established the selection-marker-free rice-based oral cholera vaccine (MucoRice-CTB) line 51A for human use by Agrobacterium-mediated co-transformation and conducted a double-blind, randomized, placebo-controlled phase I trial in Japan and the United States. Although MucoRice-CTB 51A was acceptably safe and well tolerated by healthy Japanese and U.S. subjects and induced CTB-specific antibodies neutralizing cholera toxin secreted by Vibrio cholerae, we were limited to a 6-g cohort in the U.S. trial because of insufficient production of MucoRice-CTB. Since MucoRice-CTB 51A did not grow in sunlight, we re-examined the previously established marker-free lines and selected MucoRice-CTB line 19A. Southern blot analysis of line 19A showed a single copy of the CTB gene. We resequenced the whole genome and detected the transgene in an intergenic region in chromosome 1. After establishing a master seed bank of MucoRice-CTB line 19A, we established a hydroponic production facility with LED lighting to reduce electricity consumption and to increase production capacity for clinical trials. Shotgun MS/MS proteomics analysis of MucoRice-CTB 19A showed low levels of α-amylase/trypsin inhibitor-like proteins (major rice allergens), which was consistent with the data for line 51A. We also demonstrated that MucoRice-CTB 19A had high oral immunogenicity and induced protective immunity against cholera toxin challenge in mice. These results indicate that MucoRice-CTB 19A is a suitable oral cholera vaccine candidate for Phase I and II clinical trials in humans, including a V. cholerae challenge study.

The effectiveness of green heart application to manage modifiable risk factors of coronary artery disease in Tehran Heart Center: Study protocol for a randomized controlled trial.

The burden of cardiovascular disease (CVD) is diminishing in developed countries. However, in middle- and low-income countries the CVD death rates are growing. CVD is the most common cause of death and disability in Iran and accounts for nearly half of all mortalities in Iranians. Therefore, preventive strategies by risk factor modification are a top priority in the country. Recently, Mobile-Health (mHealth) technology has been the focus of increasing interest in improving the delivery of cardiovascular prevention, targeting a combination of modifiable risk factors. This parallel-group single-blinded randomized controlled trial study has been designed to evaluate the impact of using a mHealth application on risk factors control. Individuals aged between 25 and 75 years who have documented CVD by coronary angiography in Tehran Heart Center and have at least one uncontrolled risk factor from the three including hypertension, dyslipidemia, and current cigarette smoking will be included. We are going to randomize 1544 patients into two study arms as follows: 1- Intervention: usual care + mHealth 2- Control: usual care + paper-based recommendations and educational materials. After 3 and 6 months of follow-up, the status of risk factors will be determined through outpatient visits and face-to-face interviews for both arms. Outcome: Successful risk factor control will be measured after 3 and 6 months. Nowadays, mHealth is becoming increasingly popular, providing a good opportunity for constant monitoring of risk factors and changing health behavior in a target population. Meanwhile, providing evidence for the effectiveness of health intervention delivery using mobile technologies could help health providers encourage their at-risk population to stop smoking, control blood pressure and blood cholesterol, and participate in regular physical activity. While the burden of CVD is growing in developing countries, this type of intervention can be a cost-effective way to reduce it in these countries.

[The predictive value of dynamic changes of neutrophil/lymphocyte ratio (NLR) combined with the model of end-stage liver disease (MELD) score in patients with acute-on-chronic hepatitis B liver failure].

Objective: To determine the predictive value of dynamic changes of neutrophil/lymphocyte ratio (NLR) combined with the model of end-stage liver disease (MELD) score in patients with acute-on-chronic hepatitis B liver failure. Methods: Patients with acute-on-chronic hepatitis B liver failure who were hospitalized in the Department of Hepatology of Qilu Hospital of Shandong University from January 2010 to July 2023 were retrospectively enrolled. According to the clinical outcomes of patients within 30 days of admission, they were divided into the survival group and the death group. The dynamic changes in NLR and initial values on day 3, 5, 8, and 12 in two groups were analyzed for the diagnostic value of 30-day prognosis in patients with acute-on-chronic hepatitis B liver failure. Logistic regression analysis and machine learning XGBoost algorithm were used to evaluate the risk factors influencing the prognosis of patients at 30 days. Receiver operating characteristic(ROC) curve was used to evaluate the diagnostic value of NLR and initial value change combined with MELD score on day 12 of admission in patients with chronic acute hepatitis B liver failure. Results: A total of 243 patients were enrolled in the study, including 145 patients in the survival group [115 males, 30 females, aged 25-74 (47±11)] and 98 patients in the death group [80 males, 18 females, aged 22-80 (49±13) ]. The median initial NLR of survival group and death group were 3.5 (2.1, 5.3) and 4.9 (2.9, 8.3), respectively, and the difference was statistically significant (P=0.003). The variation of NLR from the initial value on day 3, 5, 8, and 12 in the survival group [1.6 (0, 4.3), 1.9 (-0.2, 4.1), 2.0 (-0.1, 4.3) and 2.9 (0.3, 7.0), respectively] were lower than that in the death group [3.2 (0.9, 7.5), 5.1 (1.8, 7.6), 5.8 (2.0, 10.6) and 9.6 (3.5, 16.4), respectively] (all P<0.001). Logistic regression multivariate analysis showed that the changes in NLR on the 12th day and initial value (OR=1.07,95%CI:1.01-1.14, P=0.014), the changes in NLR on the 3rd day and initial value (OR=2.71, 95%CI: 1.32-5.55, P=0.007), the initial value of NLR (OR=1.18,95%CI:1.01-1.37,P=0.035) and fibrinogen (OR=0.21,95%CI:0.05-0.96,P=0.044) were related factors for death within 30 days. Machine learning XGBoost algorithm showed that the weight of the change between the NLR on the 12th day and the initial value was the highest. The area under the ROC curve of the combined MELD score was 0.812 (95%CI: 0.728-0.895), the specificity was 67.78%, and the sensitivity was 82.35%. Conclusion: Dynamic change of NLR combined with MELD score has high predictive value for the short-term prognosis of patients with acute-on-chronic hepatitis B liver failure.

Consensus Guidelines for Influenza Vaccination in Patients with Diabetes.

Influenza is a prevalent health issue encountered in daily practice. Patients with diabetes mellitus face a higher risk of infections, including influenza, owing to the compromised immune system associated with diabetes. This susceptibility arises from the potential of diabetes mellitus to weaken the immune system. Moreover, elevated blood glucose levels can create a conducive environment for the growth of bacteria and viruses. This consensus is formulated by a multidisciplinary team to serve as practical guidance for the administration of influenza vaccinations to patients with diabetes mellitus in daily practice.

Global vaccine coverage and childhood survival estimates: 1990-2019.

Objective: To quantify the association between reduction in child mortality and routine immunization across 204 countries and territories from 1990 to 2019. Methods: We used child mortality and vaccine coverage data from the Global Burden of Disease Study. We used a modified child survival framework and applied a mixed-effects regression model to estimate the reduction in deaths in children younger than 5 years associated with eight vaccines. Findings: Between 1990 and 2019, the diphtheria-tetanus-pertussis (DTP), measles, rotavirus and Haemophilus influenzae type b vaccines were significantly associated with an estimated 86.9 (95% confidence interval, CI: 57.2 to 132.4) million fewer deaths in children younger than 5 years worldwide. This decrease represented a 24.2% (95% CI: 19.8 to 28.9) reduction in deaths relative to a scenario without vaccines. The DTP and measles vaccines averted 46.7 (95% CI: 30.0 to 72.7) million and 37.9 (95% CI: 25.4 to 56.8) million deaths, respectively. Of the total reduction in child mortality associated with vaccines, 84.2% (95% CI: 83.0 to 85.1) occurred in 73 countries supported by Gavi, the Vaccine Alliance, with an estimated 45.4 (95% CI: 29.8 to 69.2) million fewer deaths from 2000 to 2019. The largest reductions in deaths associated with these four vaccines were in India, China, Ethiopia, Pakistan and Bangladesh (in order of the size of reduction). Conclusion: Vaccines continue to reduce childhood mortality significantly, especially in Gavi-supported countries, emphasizing the need for increased investment in routine immunization programmes.

Sepsis Unveils T-cell Large Granular Lymphocytic Leukemia in the Setting of End-Stage Renal Disease: A Rare Hematologic Malignancy.

Large granular lymphocytic (LGL) leukemia is a rare chronic lymphoproliferative disorder originating from natural killer cells or T lymphocytes. In this report, we present the case of a 66-year-old female initially treated for sepsis, with methicillin-sensitive Staphylococcus aureus identified on initial blood culture prompting intravenous (IV) antibiotic therapy. The patient met systemic inflammatory response syndrome criteria upon admission due to severe neutropenia. Persistent fever led to neurological symptoms, and imaging revealed lung abnormalities along with chronic changes on the CT scan of the head. Multidisciplinary consultations were sought, resulting in treatment adjustments including antifungals and filgrastim. Flow cytometry and bone marrow biopsy confirmed the diagnosis of LGL leukemia.

Risk Factors for Occupational Blood Exposure, Compliance with Policies of Infection Prevention and Control, and Costs Associated with Post Exposure Management Among Nursing Staff.

Objective: To examine the risk factors linked with occupational blood exposure (OBE) among nursing staff (NS), we pinpoint deficiencies in the compliance with policies of infection prevention and control, and assess the expenditures associated with infection prevention and control. Methods: Healthcare workers that completed an "Occupational Blood Exposure Report Form" were divided into NS (observation) group and non-NS (control) group. Univariate and multivariable analyses were conducted to compare both groups in various aspects. We also explored design patents intended to minimize occupational exposure. Results: The highest incidence of OBE was observed in the department of neurosurgery. Among NS, OBE incidence was found to be influenced by independent risk factors, such as gender, age, occupational title, work location, and incidence of sharps injuries. Protective factors against OBEs included the use of arterial blood gas needles and suture needles. Personal protective equipment (PPE) usage rates were low in both groups prior to OBEs (0.74% vs 0.00%, P > 0.05). Correct emergency management could be improved promptly by both groups following an OBE (P > 0.05). However, the observation group exhibited a higher proportion of blood expression after a sharps injury and a higher re-evaluation rate at 6 months post-exposure compared to the control group (P < 0.05). In 2018, the per capita costs of infection prevention and control for NS were the Chinese Yuan (RMB) 339.43 per individual. In response to these findings, two utility model patents have been authorized. Conclusion: The risk and protective factors related to the occurrence of OBEs were investigated in this study, suggesting that there is a need for improvement in the rate of PPE usage and the re-evaluation rate of OBEs among NS. Additionally, focused training on emergency blood expression and compliance with policies among non-NS personnel is deemed necessary.

A scoping review of triatomine control for Chagas disease prevention: current and developing tools in Latin America and the United States.

Chagas disease is an infectious disease of human and animal health concern, with 6-8 million chronic human infections and over 50,000 deaths throughout the Americas annually. Hematophagous insects of the subfamily Triatominae, also called kissing bugs, vector the protozoan parasite, Trypanosoma cruzi Chagas (Trypanosomatida: Trypanosomatidae), that causes Chagas disease. Despite the large human health burden, Chagas disease is a neglected tropical disease with inadequate funding for research and preventive practices. Given the resource-poor environment of most agencies trying to protect public health, it is critical to consider all control options for reducing vector populations and the risk of human exposure to T. cruzi to identify the most appropriate tools for each context. While numerous triatomine control methods exist, the literature lacks a compilation of the strategies used, a critical examination of their efficiency, and a particular focus on triatomine control in the United States compared to elsewhere in the Americas. Here, we present a review of the literature to assess historical intervention strategies of existing and developing triatomine control methods. For each method, we discuss progress in the field, future research to further advance the method, and limitations. While we found that pyrethroid insecticide is still the most commonly used method of triatomine and Chagas disease control, we suggest that complementing these techniques with alternative control methods in development will help to achieve Chagas disease reduction goals.

Infection prevention and control and related practices in African neonatal units: The Pan-African neonatal care assessment study (PANCAS).

BACKGROUND: The burden of neonatal mortality is primarily borne by low- and middle-income countries (LMICs), including deaths due to healthcare-associated infections (HAIs). Few studies have assessed infection prevention and control (IP&C) practices in African units caring for small and/or sick newborns aimed to reduce HAIs. METHODS: We performed a mixed-methods study composed of a survey and virtual tour to assess IP&C and related practices. We created a survey composed of multiple-choice and open-ended questions delivered to site respondents via Zoom or video equivalent. Respondents provided a virtual tour of their unit via video and the study team used a checklist to evaluate specific practices. RESULTS: We recruited 45 units caring for small and sick newborns in 20 African countries. Opportunities to optimize hand hygiene, Water, Sanitation and Hygiene (WASH) practices, Kangaroo Mother Care, and IP&C training were noted. The virtual tour offered further understanding of IP&C challenges unique to individual sites. All respondents expressed the need for additional space, equipment, supplies, education, and IP&C staff and emphasized that attention to maternal comfort was important to IP&C success. DISCUSSION: This study identified opportunities to improve IP&C practices using low-cost measures including further education and peer support through learning collaboratives. Virtual tours can be used to provide site-specific assessment and feedback from peers, IP&C specialists and environmental engineering experts.

The efficacy and safety of lecanemab 10 mg/kg biweekly compared to a placebo in patients with Alzheimer's disease: a systematic review and meta-analysis of randomized controlled trials.

Alzheimer's disease, prevalent in individuals aged 60 and above, constitutes most dementia cases and significantly impairs memory and cognitive functions. With global Alzheimer's cases projected to triple by 2050, there is a pressing need for effective interventions. Lecanemab, a monoclonal antibody targeting amyloid-beta plaques, shows promise in slowing Alzheimer's progression. Positive clinical trial results have instilled hope in patients, prompting ongoing research to advance understanding and intervention possibilities. To contribute to this knowledge base, we conducted a systematic review and meta-analysis, focusing on lecanemab's efficacy and safety at a dosage of 10 mg/kg. This comprehensive approach aimed to address gaps in the current literature, scrutinize research disparities, and guide future investigations. Applying strict inclusion/exclusion criteria, we assessed study details, participant information, and intervention specifics, using the Cochrane risk of bias tool for quality evaluation. Statistical analyses, conducted with R software, included risk ratios and mean differences, assessing heterogeneity and publication bias. The meta-analysis reveals a significant positive effect of lecanemab (10 mg/kg biweekly) on cognitive outcomes in Alzheimer's disease. Consistent reductions in ADCOMS, CDR-SB, and ADAS-cog14 scores across studies indicate drug efficacy with narrow confidence intervals and no significant heterogeneity. While TEAE shows no significant difference, heightened risks of ARIA-E and ARIA-H associated with lecanemab underscore the need for vigilant safety monitoring in clinical practice. Despite the drug efficacy, the study emphasizes a balanced assessment of benefits and potential risks associated with lecanemab, providing critical insights for clinicians evaluating its use in addressing cognitive impairment in individuals with Alzheimer's disease.

The role of nutritional interventions in the prevention and treatment of chronic lung disease of prematurity.

Chronic lung disease of prematurity or bronchopulmonary dysplasia (BPD) is a common complication of preterm birth. Nutrition may affect incidence and severity of BPD. In this context, the Section on Nutrition, Gastroenterology and Metabolism, the Pulmonary Section of the European Society for Paediatric Research (ESPR) and SPR have joined forces to review the current knowledge on nutritional issues related to BPD. The aim of this narrative review is to discuss the clinical implications for nutritional practice. Nutrient deficiencies may influence pathogenesis of BPD. Adequate nutrition and growth can play a crucial role in the prevention of and recovery from BPD. Optimal nutrition strategy is an important principle, especially in the early postnatal period. As optimal energy intake in infants at risk of BPD or with evolving BPD is not yet defined, further research with well-designed studies on nutritional strategies for preterm infants with BPD is urgently needed. IMPACT: Based on current evidence it seems reasonable to recommend that BPD diagnosed infants should receive an energy supply ranging from 120 to 150 Kcal/kg/d. Exclusive MOM feed with adequate fortification should be encouraged as this is associated with a significant reduction in the risk of BPD. Suboptimal nutritional delivery is often seen in preterm infants with BPD compared to controls.

Association of lipid levels with motor and cognitive function and decline in Parkinson's disease.

BACKGROUND: Most studies have focused on comparing blood lipid biomarkers between Parkinson's disease (PD) and normal controls (NC). However, further research is necessary to explore the impact of blood lipid levels on motor and cognitive function, as well as the progression of motor dysfunction and cognitive decline over time. Thus, the aim of this study is to investigate the relationship between blood lipid biomarkers and these indicators in individuals with PD. METHODS: The cohort study enrolled 157 PD patients and 146 NC from the Tianjin Huanhu Hospital from September 2017 to September 2019. Serum lipid fractions were detected in fasting serum samples. PD patients were followed up at 2 ± 0.6 years for clinical assessment. RESULTS: PD patients exhibited lower serum triglyceride (TG) levels as compared to NC (P = 0.008). PD male patients exhibited lower serum lipoprotein cholesterol(LDL-C) and total cholesterol (TC) levels than female patients (LDL-C: P = 0.034; TC: P = 0.019). Serum TG levels correlated significantly with Unified PD Rating Scale III, Hoehn and Yahr stage and Montreal Cognitive Assessment scores in PD patients. Additionally, serum TG levels were associated with follow-up motor function decline and cognitive decline in adjusted regression models in PD patients. CONCLUSIONS: To summarise, the study findings suggest that decreased serum TG levels are significantly associated with greater motor dysfunction, cognitive dysfunction and the greater deterioration of the two indicators.

Role of Uncertainty in Illness and Coping Strategies in Advance Directive Completion in Patients With End-stage Liver Disease.

OBJECTIVE: We examined the associations among advance directives (ADs) completion, coping, uncertainty in illness, and optimism and pessimism in patients with end-stage liver disease (ESLD). BACKGROUND: Although associations among ADs, coping, and uncertainty have been studied in patients with other life-limiting illnesses, these concepts have not been studied together in patients with ESLD. PATIENTS AND METHODS: Patients were recruited at 2 health care institutions as part of a larger prospective study. They were enrolled if they had a diagnosis of nonhepatocellular carcinoma ESLD, Sodium Model for End-Stage Liver Disease ≥15, and no prior history of liver transplantation. Uncertainty, coping, optimism, and pessimism were assessed using the Uncertainty in Illness Scale for Adults, Revised Ways of Coping Checklist, and Life Orientation Test-revised. AD documentation at the time of study enrollment was retrospectively extracted from patient medical records. RESULTS: In the sample [N = 181; median age = 57 y, 115 (64%) males], male sex [odds ratio (OR) = 4.66; 95% CI: 1.53, 14.17], being listed or under evaluation for liver transplantation (OR = 3.09; 95% CI: 1.10, 8.67), greater Sodium Model for End-Stage Liver Disease scores (OR = 1.10; 95% CI: 1.01, 1.20), and greater uncertainty (OR = 1.04; 95% CI: 1.01, 1.07) were positively associated with AD documentation. Higher coping avoidance was negatively associated with AD documentation (OR = 0.915; 95% CI: 0.840, 0.997). CONCLUSIONS: Clinicians should consider the role of uncertainty and coping measures to improve patient-specific advance care planning conversations and expand opportunities for all patients with ESLD to file an AD, especially women and patients not listed or under evaluation for transplantation.

Potential Association Between Latent Toxoplasma gondii Infection and Suicide Attempts: A Case-Control Registry-Based Study.

Toxoplasma gondii is a ubiquitous parasitic protozoan that may be an important cause of neurological and psychiatric diseases. The purpose of this case-control registry-based study was to evaluate the prevalence of T. gondii infection and related risk factors among subjects who attempted suicide by drug use and a control group at the Iranian National Registry Center for Toxoplasmosis in Mazandaran Province, northern Iran. Baseline data were collected from participants using a questionnaire, and a blood sample was taken from each individual. The plasma was prepared for serological analysis, whereas the buffy coat was used for molecular analysis. Out of 282 individuals (147 cases with suicide attempters [SA] and 135 controls), 42.9% of patients and 16.3% of control subjects were positive for anti-Toxoplasma immunoglobin G (IgG), but all participants were negative for T. gondii DNA and anti-Toxoplasma immunoglobin M. Based on multiple logistic regressions, IgG seropositivity in SA in the age group of 20-30 years was 3.22 times higher than that in the control group (p < 0.001). These findings suggest that latent T. gondii infection among SA is significantly higher than that in healthy individuals, indicating a potential association between latent toxoplasmosis and SA at least in the studied area. Further research is needed to shed light on the potential association between T. gondii and suicide among different populations and areas of the world.
