Published: January 2024

Background

Long-term care (LTC) residents with dementia can benefit from rehabilitation to improve function and quality of life. However, specific goals for rehabilitation with this population are not always clear. The purpose of this study was to describe the goals for rehabilitation for LTC residents with dementia from the perspective of residents, family, and staff.

Methods

This was a phenomenological qualitative study. LTC residents with moderate to severe dementia, family members, and staff were recruited from two LTC homes in Halifax, Nova Scotia. Data were collected through semi-structured interviews and field notes from observations with residents while they were being active within the home. Data were analyzed via the principles of thematic content analysis, mapped onto the International Classification of Functioning, Disability, and Health (ICF) Model, and reported by the participant group (i.e., residents, family, or staff).

Results

The 15 participants were three female residents aged 82 to 98 years, seven predominantly (86%) female family members aged 56 to 74 years, and five staff members (two females, three males, aged 22 to 55 years) who were physiotherapists, a physiotherapy assistant, a healthcare aide, and a registered licenced practical nurse. Most identified goals fell within the activities and participation constructs of the ICF model and focused on maintaining or improving function, mobility, and quality of life. Specific themes included preventing falls, walking or locomoting, stair climbing, maintaining activities of daily living, engaging in enjoyable exercise, maintaining independence and human connections, keeping busy, leaving the home for activities, and participating in group activities.

Conclusions

Rehabilitation goals for LTC residents living with dementia often focus on quality of life and functional activities and participation in LTC and family activities and events. Function and quality of life are interrelated, whereby functional goals influence quality of life. While some goals focus on improvement in function, maintenance or prevention of decline were also key elements. Future work should ensure rehabilitation interventions are developed relative to individually identified goals, and interventional success is measured in relation to the goal.

Published: January 2024

Background

Cumulative malaria parasite exposure in endemic regions often results in the acquisition of partial immunity and asymptomatic infections. There is limited information on how host-parasite interactions mediate the maintenance of chronic symptomless infections that sustain malaria transmission.

Methods

Here, we determined the gene expression profiles of the parasite population and the corresponding host peripheral blood mononuclear cells (PBMCs) from 21 children (< 15 years). We compared children who were defined as uninfected, asymptomatic and those with febrile malaria.

Results

Children with asymptomatic infections had a parasite transcriptional profile characterized by a bias toward trophozoite stage (~ 12 h-post invasion) parasites and low parasite levels, while early ring stage parasites were characteristic of febrile malaria. The host response of asymptomatic children was characterized by downregulated transcription of genes associated with inflammatory responses, compared with children with febrile malaria,. Interestingly, the host responses during febrile infections that followed an asymptomatic infection featured stronger inflammatory responses, whereas the febrile host responses from previously uninfected children featured increased humoral immune responses.

Conclusions

The priming effect of prior asymptomatic infection may explain the blunted acquisition of antibody responses seen to malaria antigens following natural exposure or vaccination in malaria endemic areas.
Assessment of BlaTEM, BlaSHV, and BlaCTX-M genes of antibiotic resistance in Gram-negative bacilli causing urinary tract infections in Khartoum State: a cross-sectional study
Authors: Mohammedkheir Manal Ismail Abdalla , Gaafar Elsheikh Mahgoub , AbdAlla Eltayeb GareebAlla Eltayeb
Published: January 2024

Background

Gram-negative bacilli are the most common etiological agents responsible for urinary tract infections. The prevalence of antibiotic resistance in Gram-negative bacilli is increasing at a rapid pace globally, which is constraining the available choices for UTI treatment. The objectives of this study are to identify the most common causal organisms of urinary tract infections (UTIs), and to determine their drug resistance patterns.

Materials and methods

This was a cross-sectional hospital-based study conducted at El-Amal Hospital, Bahri Teaching Hospital, and Al-Baraha Hospital, Khartoum State, from March to October 2022. Urine samples from patients suspected to have UTI were collected, and patients with confirmed UTI by laboratory investigations and yielded culture growth were enrolled. Antibiotic sensitivity testing and PCR testing of the blaTEM, blaSHV, and blaCTX-M genes were done.

Results

This study included 50 patients with UTI out of 229 suspected patients (21.8%). The most prominent group of patients was older than 60 years (40%); the majority were females (70%). Escherichia coli was the most prevalent isolated organism (50%), followed by Klebsiella oxytoca (24%), Klebsiella pneumoniae (20%), Pseudomonas aeruginosa (4%), and Citrobacter freundii (2%). A small percentage of organisms were resistant to colistin (17%). However, 77% were resistant to amikacin, 97.6% to cefotaxime, 96.8% to ceftazidime, 97.6% to ceftriaxone, 96.8% to cefixime, 87.6% to ciprofloxacin, 88.4% to gentamycin, 62% to imipenem, 67.6% to meropenem, 87.6% to norfloxacin, and 95.6% to trimethoprim. The overall resistance of isolated gram-negative organisms was 81%. The most prevalent gene for the resistance was blaTEM (100%), followed by blaCTX-M (94%), and then blaSHV (84%).

Conclusion

Escherichia coli and Klebsiella species were the most commonly isolated uropathogens in this study, and the majority were highly resistant to most of the antimicrobial agents tested. Resistance genes blaTEM, blaCTX-M, and blaSHV are very common in uropathogens.

Authors: Lanuza Pamela Danielle T. , Garcia Jao Jarro B. , Turalde Christian Wilson R. , Prado Mario Jr. B.
Published: January 2024

Background

Tetanus is a life-threatening but preventable neurologic disorder characterized by trismus and muscle spasms. Despite its decreasing global incidence, it remains to be endemic in resource-limited settings such as the Philippines. This study aimed to determine the incidence, demographic characteristics, risk factors, clinical presentation, management, complications, and outcomes of non-neonatal tetanus cases in a tertiary hospital in the Philippines. It also aimed to compare the clinical profile and outcomes between the adult and pediatric subgroups.

Methods

This study used a retrospective cross-sectional design including all adult and pediatric non-neonatal tetanus patients admitted at the University of the Philippines - Philippine General Hospital from January 2012 to June 2023. Data was extracted from department censuses and inpatient charts.

Results

One hundred thirty-eight cases were included. The incidence rate was 0.03%, while mortality rate was 29%. Majority of patients were males presenting with trismus and spasms after sustaining a puncture wound. Chronic hypertension was associated with an increased hazard of death by 4.5 times (p = 0.004), while treatment with magnesium sulfate was associated with a decreased hazard of death by 35 times (p = 0.005). The mode of infection and the medications administered differed between the adult and pediatric subgroups.

Conclusions

Although the total number of cases has decreased over the past decade, tetanus remains to have a high incidence and mortality rate in the Philippines. Increasing vaccination coverage, improving public awareness, and educating health professionals can help reduce morbidity and mortality from this disease.

Published: January 2024

Background

Despite several clinical trials, the use of corticosteroid therapy for treating immunoglobulin A nephropathy (IgAN) remains controversial. We aimed to describe the use of corticosteroid therapy combined with supportive therapy in Norwegian patients with IgAN who had progressed to end-stage kidney disease.

Methods

We conducted a retrospective cohort study using data from the Norwegian Renal Registry. Overall, 143 patients with primary IgAN who progressed to end-stage kidney disease were divided into two groups: the corticosteroid group, who had been treated with corticosteroids and supportive therapy, and the non-corticosteroid group, which had underwent only supportive therapy. The kidney function, time to end-stage kidney disease, and adverse effects were described. The observation period lasted from the diagnostic kidney biopsy until the initiation of kidney replacement therapy.

Results

Of the 143 included patients, 103 underwent supportive therapy alone, and 40 were treated with corticosteroids. Most patients (94%) were treated with renin-angiotensin-system blockade, and all patients reached end-stage kidney disease after a median of 5 years (interquartile range; 2–9 years). Time from diagnosis until end-stage kidney disease was similar in the two study groups (p = 0.98). During 6 months of corticosteroid therapy, median eGFR declined from 21 (interquartile range; 13–46) mL/min/1.73 m2 to 20 (interquartile range; 12–40) mL/min/1.73 m2, and median proteinuria decreased from 5.5 g/24 h to 3.0 g/24 h. Most patients (87.5%) treated with corticosteroids reported adverse events. In our linear regression analysis investigating the time to ESKD, we found that age (β = -0.079, p = 0.008) and proteinuria at diagnosis (β = -0.50, p = 0.01) exhibited statistically significant associations with a delay in the progression to ESKD.

Conclusions

In this cohort of Norwegian patients with IgAN, corticosteroid therapy did not affect the time from diagnosis until end-stage kidney disease among a cohort of patients who all reached end-stage kidney disease. The treatment was also associated with adverse effects.

Authors: Huang Huanjia , Zhang Jian , Lin Jinmei , Shi Shengliang
Published: January 2024

Objective

This meta-analysis and systematic review were conducted to comprehensively evaluate the efficacy and safety of mesenchymal stem cells in patients with acute ischemic stroke.

Method

We conducted a manual search of electronic databases, including PubMed, Embase, the Cochrane Library, and Web of Science, with a search deadline set for February 1, 2023. Data analysis was performed using Stata version 15.0.

Result

A total of 9 randomized controlled studies were included, involving a total of 316 people, including 159 mesenchymal stem cells and 147 control groups. Results of meta-analysis: Compared to a placebo group, the administration of mesenchymal stem cells resulted in a significant reduction in the National Institutes of Health Stroke Scale (NIHSS) scores among patients diagnosed with acute ischemic stroke [SMD=-0.99,95% CI (-1.93, -0.05)]. Compared to placebo, barthel index [SMD = 0.48,95% CI (-0.55,1.51)], modified rankin score [SMD = 0.45, 95% CI (1.11, 0.21)], adverse events (RR = 0.68, 95% CI (0.40, 1.17)] the difference was not statistically significant.

Conclusion

Based on current studies, mesenchymal stem cell transplantation can ameliorate neurological deficits in patients with ischemic stroke to a certain extent without increasing adverse reactions. However, there was no significant effect on Barthel index and Modified Rankin score.

Published: January 2024

Glioblastoma multiforme (GBM) is the most aggressive brain cancer with a poor prognosis. Therefore, the correlative molecular markers and molecular mechanisms should be explored to assess the occurrence and treatment of glioma.WB and qPCR assays were used to detect the expression of CXCL5 in human GBM tissues. The relationship between CXCL5 expression and clinicopathological features was evaluated using logistic regression analysis, Wilcoxon symbolic rank test, and Kruskal–Wallis test. Univariate, multivariate Cox regression and Kaplan–Meier methods were used to assess CXCL5 and other prognostic factors of GBM. Gene set enrichment analysis (GSEA) was used to identify pathways associated with CXCL5. The correlation between CXCL5 and tumor immunoinfiltration was investigated using single sample gene set enrichment analysis (ssGSEA) of TCGA data. Cell experiments and mouse subcutaneous transplanted tumor models were used to evaluate the role of CXCL5 in GBM. WB, qPCR, immunofluorescence, and immunohistochemical assays showed that CXCL5 expression was increased in human GBM tissues. Furthermore, high CXCL5 expression was closely related to poor disease-specific survival and overall survival of GBM patients. The ssGSEA suggested that CXCL5 is closely related to the cell cycle and immune response through PPAR signaling pathway. GSEA also showed that CXCL5 expression was positively correlated with macrophage cell infiltration level and negatively correlated with cytotoxic cell infiltration level. CXCL5 may be associated with the prognosis and immunoinfiltration of GBM.
Impact of the Sars-Cov-2 outbreak on the initial clinical presentation of new solid cancer diagnoses: a systematic review and meta-analysis
Authors: Marty Simon , Lamé Guillaume , Guével Etienne , Priou Sonia , Chatellier Gilles , Tournigand Christophe , Kempf Emmanuelle ,   a CRAB* initiative
Published: January 2024

Background

The COVID-19 pandemic might have delayed cancer diagnosis and management. The aim of this systematic review was to compare the initial tumor stage of new cancer diagnoses before and after the pandemic.

Methods

We systematically reviewed articles that compared the tumor stage of new solid cancer diagnoses before and after the initial pandemic waves. We conducted a random-effects meta-analysis to compare the rate of metastatic tumors and the distribution of stages at diagnosis. Subgroup analyses were performed by primary tumor site and by country.

Results

From 2,013 studies published between January 2020 and April 2022, we included 58 studies with 109,996 patients. The rate of metastatic tumors was higher after the COVID-19 outbreak than before (pooled OR: 1.29 (95% CI, 1.06-1.57), I2: 89% (95% CI, 86-91)). For specific cancers, common ORs reached statistical significance for breast (OR: 1.51 (95% CI 1.07-2.12)) and gynecologic (OR: 1.51 (95% CI 1.04-2.18)) cancers, but not for other cancer types. According to countries, common OR (95% CI) reached statistical significance only for Italy: 1.55 (1.01-2.39) and Spain:1.14 (1.02-1.29). Rates were comparable for stage I-II versus III-IV in studies for which that information was available, and for stages I-II versus stage III in studies that did not include metastatic patients.

Conclusions

Despite inter-study heterogeneity, our meta-analysis showed a higher rate of metastatic tumors at diagnosis after the pandemic. The burden of social distancing policies might explain those results, as patients may have delayed seeking care.
Evaluation of the tolerability and safety of [225Ac]Ac-PSMA-I&T in patients with metastatic prostate cancer: a phase I dose escalation study
Authors: Ling Sui wai , van der Veldt Astrid A. M. , Konijnenberg Mark , Segbers Marcel , Hooijman Eline , Bruchertseifer Frank , Morgenstern Alfred , de Blois Erik , Brabander Tessa
Published: January 2024

Background

Life expectancy of patients with metastatic castration-resistant prostate cancer (mCRPC) is still limited despite several systemic treatments. Within five years after diagnosis of primary prostate cancer, 10–20% of the patients have mCRPC and curation is not an option. Radionuclide therapy (RNT) targeted against prostate-specific membrane antigen (PSMA) emerged as a new treatment option and showed effective results in patients with mCRPC. Survival benefit after [177Lu]Lu-PSMA RNT has already been demonstrated in several clinical trials. However, [225Ac]Ac-PSMA (225Ac-PSMA) appears to be an even more promising radiopharmaceutical for the treatment of mCRPC. The use of alpha emitting radionuclides offers advantages over beta emitting radionuclides due to the high linear energy transfer effective for killing tumor cells and the limited range to reduce the radiation effects on the healthy tissue. However, these results are based on retrospective data and safety data of 225Ac-PSMA are still limited. Therefore, a prospective trial is needed to determine the optimal amount of activity that can be administered.

Methods

The 225Ac-PSMA-Imaging & Therapy (I&T) trial is an investigator-initiated phase I, single-center, open label, repeated dose-escalation and expansion trial. Patient with PSMA-positive mCRPC after at least one line of chemotherapy and/or one line of nonsteroidal antiandrogen will be treated with 225Ac-PSMA-I&T in increasing amount of activity per cycle. Dose-escalation following an accelerated 3 + 3 design which allows to open the next dose-level cohort in the absence of dose limiting toxicity while the previous one is still ongoing. Up to 4 treatment cohorts will be explored including up to 3 dose-escalation cohorts and one expansion cohort where patients will be administered with the recommended dose. A total of up to 30 patients will be enrolled in this trial. All patients will be evaluated for safety. Additionally, dosimetry was performed for the patients in the dose-escalation cohorts after the first 225Ac-PSMA-I&T administration.

Discussion

This trial will assess the safety and tolerability of 225Ac-PSMA-I&T in patients with mCRPC to recommend the optimal dose for the phase II trial.

Authors: Ali Esraa , Červenková Lenka , Pálek Richard , Ambrozkiewicz Filip , Hošek Petr , Daum Ondrej , Liška Václav , Hemminki Kari , Trailin Andriy
Published: January 2024

Background

The prognostic significance of mast cells and different phenotypes of macrophages in the microenvironment of hepatocellular carcinoma (HCC) following resection is unclear. We aimed in this study to assess the local distribution of infiltrating macrophages and mast cells of specific phenotypes in tissues of HCC and to evaluate their prognostic values for survival of post-surgical patients.

Methods

The clinicopathological and follow-up data of 70 patients with HCC, who underwent curative resection of tumor from 1997 to 2019, were collected. The infiltration of CD68+ and CD163+ macrophages and CD117+ mast cells was assessed immunohistochemically in representative resected specimens of HCC and adjacent tissues. The area fraction (AF) of positively stained cells was estimated automatically using QuPath image analysis software in several regions, such as tumor center (TC), inner margin (IM), outer margin (OM), and peritumor (PT) area. The prognostic significance of immune cells, individually and in associations, for time to recurrence (TTR), disease-free survival (DFS), and overall survival (OS) was evaluated using Kaplan-Meier and Cox regression analyses.

Results

High AF of CD68+ macrophages in TC and IM and high AF of mast cells in IM and PT area were associated with a longer DFS. High AF of CD163+ macrophages in PT area correlated with a shorter DFS. Patients from CD163TChigh & CD68TClow group had a shorter DFS compared to all the rest of the groups, and cases with CD163IMlow & CD68IMhigh demonstrated significantly longer DFS compared to low AF of both markers. Patients from CD68IMhigh & CD163PTlow group, CD117IMhigh & CD163PTlow group, and CD117PThigh & CD163PTlow group had a significantly longer DFS compared to all other combinations of respective cells.

Conclusions

The individual prognostic impact of CD68+ and CD163+ macrophages and mast cells in the microenvironment of HCC after resection depends on their abundance and location, whereas the cumulative impact is built upon combination of different cell phenotypes within and between regions.

Authors: Schaal Luisa Fioravanti , Meneghim Roberta Lilian Fernandes de Sousa , Ferraz Lucieni Cristina Barbarini , Padovani Carlos Roberto , Victoria Cassiano , Schellini Silvana Artioli
Published: January 2024

Background

Trachoma is a notifiable disease in the state of São Paulo– Brazil. However, in Jaú, a municipality located in this state, in the last 10 years there are no records of cases. This study purpose is to assess if there are cases of inflammatory trachoma in schoolchildren aged 1 to 9 years in the municipality of Jaú as well if it is possible to detect clusters areas of the disease to establish elimination programs.

Methods

An epidemiological study was performed in 2018, involving a stratified random sample of schoolchildren aged 1- to 9-year-old, from public day care centers and elementary schools in the municipality of Jaú. A trachoma screening following the criteria of the World Health Organization (WHO) and the distribution of cases was assessed using geoprocessing.

Results

Four thousand-six hundred-nineteen children from 44 elementary schools were examined, and 126 children with active trachoma were detected, with an adjusted prevalence rate of 2.65%. The prevalence was higher (3.01%) in children aged 6- to 9-year-old compared to children aged 1-to 5-year-old (2.42%). There were clusters with a higher concentration of positive cases of the disease in three schools located in the neighborhoods with lower socioeconomic conditions.

Conclusion

Inflammatory trachoma still present in children aged 1- to 9-year-old in the city of Jaú. The positive cases were located mainly in areas with low socioeconomic conditions. Health promotion with active search and periodical treatment must be planned to fight this important blinding cause, that persists in our municipality.

Authors: Fernandes Danielle , Kemigisha Elizabeth , Achen Dorcus , Akatukwasa Cecilia , Ruzaaza Gad Ndaruhutse , Coene Gily , Delobelle Peter , Nyakato Viola N. , Michielsen Kristien
Published: January 2024

Background

Previous initiatives concerning adolescent sexual and reproductive health (SRH) education in Low-or-Middle Income Countries (LMICs) have been limited by cultural norms and misinformation perpetuated within families. Responding to the paucity of research on the implementation of SRH interventions in LMICs and limited knowledge regarding their mechanisms, this study undertakes a process evaluation of a parent-focused intervention to promote parent-adolescent communication about SRH in Uganda.

Methods

This paper explores the implementation, contextual factors and mechanisms of impact of the intervention, using the Medical Research Council (MRC) guidelines for process evaluations. Implementation was evaluated through indicators of dose, fidelity and adaptations, acceptability and feasibility. The contextual factors and mechanisms of impact were evaluated to refine the intervention’s causal assumptions. Data was collected during April - October 2021 in South-Western Uganda using a mixed-methods approach, including document analysis, intervention observations, interviews, focus group discussions and most significant change stories.

Results

The acceptability of the intervention was related to its community engagement, the strong rapport with delivery agents, and individual characteristics of participants. Five contextual factors influencing implementation were highlighted; (i) cultural norms, (ii) perceptions about youth SRH, (iii) poverty, (iv) Covid-19 pandemic, and (v) prior research projects in the community. When considering the intervention’s mechanisms of impact, four causal pathways were identified; (i) Awareness of SRH needs helped parents overcome stigma, (ii) Parenting skills training improved SRH communication, (iii) Group learning stimulated shared parenting, and (iv) Group learning improved co-parenting.

Conclusion

The paper presented three key learnings and corresponding recommendations for future research. Firstly, implementation success was credited to meaningful community engagement which improved acceptability and uptake. Secondly, the complex influences of contextual factors highlighted the need for contextual analysis in research studies to inform intervention design. Finally, this evaluation recognised the interplay between mechanisms of impact and suggested further research consider such combined impacts when designing intervention content.

Published: January 2024

Background

This study aimed to explore the knowledge, attitude, and practice (KAP) toward exercise therapy of patients with major depressive disorder (MDD).

Methods

This cross-sectional study was conducted at the First Hospital of Shanxi Medical University between April and October 2023 in patients with MDD. A self-designed questionnaire was used to evaluate the KAP (Cronbach’s α = 0.787). The minimum-maximum scores were 2–23 for knowledge, 11–55 for attitude, and 7–35 for practice.

Results

A total of 494 valid questionnaires were analyzed. The mean KAP dimension scores were 15.39 ± 3.34/23 (66.91%), 36.54 ± 19.33/55 (66.44%), and 19.33 ± 5.22/35 (55.23%), indicating poor knowledge, negative attitude, and weak practice. Multivariable logistic regression analysis showed that female (OR = 0.613, 95%CI: 0.376-1.000, P = 0.050), urban residence (OR = 0.443, 95%CI: 0.259–0.758, P = 0.003), suburban residence (OR = 0.047, 95%CI: 0.016–0.138, P < 0.001), higher income (OR = 3.889–7.928, all P < 0.001), and unclear self-reported depression level (OR = 0.078, 95%CI: 0.027–0.221, P < 0.001) were independently associated with the knowledge scores. Knowledge scores (OR = 1.102, 95%CI: 1.022–1.188, P = 0.011), female gender (OR = 0.437, 95%CI: 0.246–0.776, P = 0.005), city (OR = 0.410, 95%CI: 0.226–0.744, P = 0.003), married (OR = 3.577, 95%CI: 1.751–7.650, P < 0.001), higher income (OR = 0.065–0.392, both P < 0.050), depressive trend (OR = 2.640, 95%CI: 1.110–6.278, P = 0.028), high depression score level (OR = 0.176, 95%CI: 0.104-0.300, P < 0.001), and unclear self-reported depression score (OR = 0.023, 95%CI: 0.007–0.076, P < 0.001) were independently associated with the attitude scores. Finally, knowledge scores (OR = 1.130, 95%CI: 1.051–1.215, P = 0.001), attitude scores (OR = 1.199, 95%CI: 1.124–1.280, P < 0.001), and city (OR = 0.583, 95%CI: 0.352–0.965, P = 0.036) were independently associated with the practice scores. The structural equation modeling analysis showed that knowledge, but not attitude (β = 0.103, P = 0.092) or practice (β = 0.034, P = 0.603), influenced the depression level (β=-0.074, P < 0.001); attitude influenced practice (β = 0.369, P < 0.001).

Conclusion

The KAP toward exercise among MDD patients is poor in Shanxi. Females, people living in urban or suburban areas, with lower income, and self-reported unclear depression levels should be targeted by education interventions.
Association between thymic hyperplasia and serum calcium level in Graves’ disease
Authors: Zeng Jing , Li Lan , Wei Dong
Published: January 2024

Background

Graves' disease increases bone resorption in hyperthyroidism, leading to elevated serum calcium levels and a negative bone balance. Thymic hyperplasia is observed in some Graves' disease patients. What's more, there have been a few reports of increased serum calcium and severe osteoporosis induced by Graves’ disease with thymic hyperplasia. It remains unclear whether Graves’ disease with thymic hyperplasia is associated with higher serum calcium levels. Our study aimed to investigate the possibility of elevated serum calcium levels and aggravated bone mobilization in Graves’ disease patients with thymic hyperplasia.

Methods

Newly diagnosed and untreated patients with Graves' disease (n = 96) were enrolled. They were divided into two groups based on the incidental detection of thymic hyperplasia during imaging. Albumin, alkaline phosphatase, calcium, free triiodothyronine, free thyroxine, thyroid-stimulating hormone, and thyrotrophin receptor antibody (TRAb) were measured, and a computerized tomography of the chest was obtained.

Results

Patients with Graves’ disease who had thymic hyperplasia were notably younger (P=0.018) and exhibited higher serum calcium levels (P=0.001) compared to those with Graves’ disease without thymic hyperplasia. In the multiple regression analysis, thymic hyperplasia, TRAb, and female gender were significant variables associated with elevated serum calcium levels in patients with Graves' disease, collectively accounting for 31.7% of the variation in serum calcium.

Conclusions

Graves’ disease patients with thymic hyperplasia showed higher serum calcium levels. thymic hyperplasia, TRAb, and female gender were found to be correlated with increased serum calcium levels in Graves’ disease, suggesting a potential association between thymic hyperplasia and bone mobilization in Graves’ disease.
Non-invasive ventilation in the care of patients with chronic obstructive pulmonary disease with palliative care needs: a scoping review

Published: January 2024

Background

Patients with severe chronic obstructive pulmonary disease (COPD) could have palliative care (PC) needs because of unmet needs such as dyspnoea. This may lead to anxiety and may have an impact on patients’ ability to perform daily activities of living. PC can be started when patients with COPD have unmet needs and can be provided alongside disease-modifying therapies. Non-invasive ventilation (NIV) could be an important measure to manage dyspnoea in patients with COPD in need of PC. A scoping review was conducted to gain an overview of the existing research and to identify knowledge gaps. The aim of this scoping review was to systematically map published studies on the use of NIV in patients with COPD with PC needs, including the perspectives and experiences of patients, families, and healthcare professionals (HCPs).

Methods

This review was conducted following the framework of Arksey and O’Malley. The reporting of the review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. The review protocol was published. AMED, CINAHL, Embase, MEDLINE, PEDro, and PsycInfo were searched from inception to November 14, 2022. The included studies had to report the perspectives and experiences of COPD patients, relatives, and HCPs regarding NIV in the care of patients with COPD with PC needs. In pairs, the authors independently assessed studies’ eligibility and extracted data. The data were organised thematically. The results were discussed in a consultation exercise.

Results

This review included 33 papers from 32 studies. Four thematic groupings were identified: preferences and attitudes towards the use of NIV; patient participation in the decision-making process of NIV treatment; conflicting results on the perceived benefits and burdens of treatment; and heterogenous clinical outcomes in experimental studies. Patients perceived NIV as a ‘life buoy’ to keep them alive. Many patients wanted to take part in the decision-making process regarding NIV treatment but expressed varying degrees of inclusion by HCPs in such decision-making. Conflicting findings were identified regarding the perceived benefits and burdens of NIV treatment. Diversity in heterogeneous clinical outcomes were reported in experimental studies.

Conclusions

There is a need for more studies designed to investigate the effectiveness of NIV as a palliative measure for patients with COPD with PC needs using comprehensive outcomes. It is especially important to gain more knowledge on the experiences of all stakeholders in the use of home-based NIV treatment to these patients.

Background

Medical students’ empathy toward patients with Alzheimer’s is rarely found in formal medical curricula. Based on Vygotsky’s theory, watching films and reflection can be considered as effective methods to improve empathy. The present study aimed to explore medical students’ perceptions of empathy toward patients with Alzheimer after participating in an educational program by using interactive video based on Vygotsky’s theory.

Methods

This qualitative study was conducted at Tehran University of Medical Sciences in 2022. The population included all 40 medical students. Firstly, the Still Alice movie which is about the feelings of a professor who was diagnosed with Alzheimer’s disease was shown to the students. Secondly, the students reflected on their experiences of watching the movie. Thirdly, a session was held for group discussion on the subject of the movie, the patient’s feelings, the doctor’s attitude, the social environment surrounding the patient shown in the movie, and the necessity of empathy toward patients with Alzheimer’s disease. The reflection papers were analyzed using the conventional qualitative content analysis method.

Results

After analyzing 216 codes from 38 reflection papers, four categories, including communication with a patient with Alzheimer’s, understanding the patient with Alzheimer’s as a whole, medical science development, and the student’s individual ideology, were extracted.

Conclusion

Reflection and group discussion after watching movie by providing opportunities for social interaction about personal interpretations will lead to active role in enhancing empathy. Based on the perceptions of the medical students, they gained a perspective to consider the patient as a whole and pay attention to establishing a proper relationship with the patient.

Published: January 2024

Background

Welfare technology interventions have become increasingly important in home-based palliative care for facilitating safe, time-efficient, and cost-effective methods to support patients living independently. However, studies evaluating the implementation of welfare technology innovations are scarce, and the empirical evidence for sustainable models using technology in home-based palliative care remains low. This study aimed to report on the use of the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework to assess the implementation of remote home care (RHC) a technology-mediated service for home-living patients in the palliative phase of cancer. Furthermore, it aimed to explore areas of particular importance determining the sustainability of technologies for remote palliative home-based care.

Methods

A secondary analysis of data collected by semi-structured interviews with patients with cancer in the palliative phase, focus groups, and semi-structured interviews with healthcare professionals (HCPs) experienced with RHC was performed. A deductive reflexive thematic analysis using RE-AIM dimensions was conducted.

Results

Five themes illustrating the five RE-AIM dimensions were identified: (1) Reach: protective actions in recruitment - gatekeeping, (2) Effectiveness: potential to offer person-centered care, (3) Adoption: balancing high touch with high tech, (4) Implementation: moving towards a common understanding, and (5) Maintenance: adjusting to what really matters. The RE-AIM framework highlighted that RHC implementation for patients in the palliative phase of cancer was influenced by HCP gatekeeping behavior, concerns regarding abandoning palliative care as a high-touch specialty, and a lack of competence in palliative care. Although RHC facilitated improved routines in patients’ daily lives, it was perceived as a static service unable to keep pace with disease progression.

Conclusions

A person-centered approach that prioritizes individual needs and preferences is necessary for providing optimal care. Although technologies such as RHC are not a panacea, they can be integrated as support for increasingly strained health services.

Background

Higher maternal pre-pregnancy body mass index (BMI) is associated with adverse pregnancy and perinatal outcomes. However, whether these associations are causal remains unclear.

Methods

We explored the relation of maternal pre-/early-pregnancy BMI with 20 pregnancy and perinatal outcomes by integrating evidence from three different approaches (i.e. multivariable regression, Mendelian randomisation, and paternal negative control analyses), including data from over 400,000 women.

Results

All three analytical approaches supported associations of higher maternal BMI with lower odds of maternal anaemia, delivering a small-for-gestational-age baby and initiating breastfeeding, but higher odds of hypertensive disorders of pregnancy, gestational hypertension, preeclampsia, gestational diabetes, pre-labour membrane rupture, induction of labour, caesarean section, large-for-gestational age, high birthweight, low Apgar score at 1 min, and neonatal intensive care unit admission. For example, higher maternal BMI was associated with higher risk of gestational hypertension in multivariable regression (OR = 1.67; 95% CI = 1.63, 1.70 per standard unit in BMI) and Mendelian randomisation (OR = 1.59; 95% CI = 1.38, 1.83), which was not seen for paternal BMI (OR = 1.01; 95% CI = 0.98, 1.04). Findings did not support a relation between maternal BMI and perinatal depression. For other outcomes, evidence was inconclusive due to inconsistencies across the applied approaches or substantial imprecision in effect estimates from Mendelian randomisation.

Conclusions

Our findings support a causal role for maternal pre-/early-pregnancy BMI on 14 out of 20 adverse pregnancy and perinatal outcomes. Pre-conception interventions to support women maintaining a healthy BMI may reduce the burden of obstetric and neonatal complications.

Mosquito odour-baited mass trapping reduced malaria transmission intensity: a result from a controlled before-and-after intervention study

Published: January 2024

Background

Conventional vector control strategies have significantly reduced the malaria burden. The sustainability of these methods is currently challenged. Odour-based traps are emerging technologies that can complement the existing tools. Implementation of odour-based traps for mass trapping is limited due to the restricted range of vectors caught with available carbon dioxide-dependent lures, and the lack of comprehensive field studies. The objective of this study was to assess the impact of odour-mediated mass trapping targeting outdoor vectors, using a synthetic cattle urine lure that attracts a wide range of vector species in a variety of physiological states, on malaria prevalence and entomological parameters to determine malaria transmission intensities.

Methods

A controlled before-and-after study was conducted in two rural communities in southern Ethiopia. Baseline monthly entomological and seasonal cross-sectional malaria prevalence surveys were conducted in both communities for a year. Then, mass trapping of mosquitoes was conducted in one of the villages, while the monthly entomological surveillance and seasonal malaria prevalence surveys continued in both villages. Generalised linear mixed models were constructed and tested to determine which factors were significantly affected by the intervention.

Results

Mass trapping contributed to the reduction of the population of the principal malaria vector, Anopheles arabiensis, and the associated entomological indicators, the human bite rate (HBR) and the entomological inoculation rate (EIR), in the intervention village compared to the control village. The intervention village had an average HBR by An. arabiensis of 3.0 (95% CI 1.4–4.6) during the peak malaria transmission season, compared to 10.5 (95% CI − 0.5–21.5; P < 0.0001) in the control village. The intervention village (mean 0.02, 95% CI − 0.05–0.4.8) had a daily EIR eight times lower than the control village (mean 0.17, 95% CI), which likely contributed to the reduced malaria prevalence in the intervention community following its introduction by ca. 60% (95% CI 55–63).

Conclusions

The combined use of odour-based mass trapping and conventional control strategies coincided with a reduction of human-vector contact and malaria prevalence, providing support for odour-baited technologies as a viable option for next-generation vector control tools. Further cluster-randomised control studies are recommended in different eco-epidemiological settings with varying malaria transmission intensities.

Background

Previous research in FMS-like tyrosine kinase 3 ligands (FLT3L) has primarily focused on their potential to generate dendritic cells (DCs) from bone marrow progenitors, with a limited understanding of how these cells affect CD8 T cell function. In this study, we further investigated the in vivo role of FLT3L for the immunomodulatory capabilities of CD8 T cells.

Methods

Albumin-conjugated FLT3L (Alb-FLT3L) was generated and applied for translational medicine purposes; here it was used to treat naïve C57BL/6 and OT1 mice for CD8 T cell response analysis. Syngeneic B16ova and E.G7ova mouse models were employed for adoptive cell transfer to evaluate the effects of Alb-FLT3L preconditioning of CD8 T cells on tumor progression. To uncover the underlying mechanisms of Alb-FLT3L modulation, we conducted bulk RNA-seq analysis of the CD44high CD8 T cells. STAT1-deficient mice were used to elucidate the functional roles of Alb-FLT3L in the modulation of T cells. Finally, antibody blockade of type one interferon signaling and in vitro coculture of plasmacytoid DCs (pDCs) with naive CD8 T cells was performed to determine the role of pDCs in mediating regulation of CD44high CD8 T cells.

Results

CD44high CD8 T cells were enhanced in C57BL/6 mice administrated with Alb-FLT3L. These CD8 T cells exhibited virtual memory features and had greater proliferative and effective functions. Notably, the adoptive transfer of CD44high naïve CD8 T cells into C57BL/6 mice with B16ova tumors led to significant tumor regression. RNA-seq analysis of the CD44high naïve CD8 T cells revealed FLT3L to induce CD44high CD8 T cells in a JAK-STAT1 signaling pathway-dependent manner, as supported by results indicating a decreased ability of FLT3L to enhance CD8 T cell proliferation in STAT1-deficient mice as compared to wild-type control mice. Moreover, antibody blockade of type one interferon signaling restricted the generation of FLT3L-induced CD44high CD8 T cells, while CD44 expression was able to be induced in naïve CD8 T cells cocultured with pDCs derived from FLT3L-treated mice. This suggests the crucial role of pDCs in mediating FLT3L regulation of CD44high CD8 T cells.

Conclusions

These findings provide critical insight and support the therapeutic potential of Alb-FLT3L as an immune modulator in preconditioning of naïve CD8 T cells for cancer immunotherapy.
