Objectives

To estimate the healthcare costs associated with post-stroke dysphagia during acute hospitalisation and to identify factors influencing these costs in a tertiary hospital setting in Vietnam.

Design

A cross-sectional study using clinical and billing data from hospital records.

Setting

The study was conducted at the Neurology Center of Bach Mai Hospital, a tertiary care facility in Hanoi, Vietnam, between June 2020 and January 2022.

Participants

A total of 951 patients aged ≥18 years with acute ischaemic stroke confirmed by CT or MRI were included. Dysphagia was assessed using the Gugging Swallowing Screen.

Outcome measures

Direct healthcare costs during hospitalisation were collected from the hospital billing system and categorised as medications, diagnostic imaging, medical supplies, accommodation, food, procedures and laboratory tests. All costs were converted to USD. Associations between patient characteristics and total healthcare costs were analysed using generalised linear models (Gamma distribution with log link), applying robust standard errors.

Results

The median treatment cost was 10.08 million VND (436.24 USD) in the dysphagia group vs 6.37 million VND (275.78 USD) in the non-dysphagia group. Costs increased with dysphagia severity, reaching 22.64 million VND (979.49 USD) among patients with severe dysphagia. In multivariate analysis, dysphagia was associated with a 21% increase in costs (exp(β) = 1.21; 95% CI 1.10 to 1.33; p14, pneumonia, prolonged hospitalisation and higher educational level.

Conclusions

Post-stroke dysphagia substantially increases acute hospitalisation costs in Vietnam. Early screening, standardised management and preventive care for complications may improve outcomes and reduce costs.

Volume kinetics of crystalloid and colloid solutions administered to healthy anesthetized cats

by Chien-Hsien Kitty Yang, Xiu Ting Yiew, Robert G. Hahn, William Muir, Carolyn Kerr, Shane Bateman

This prospective experimental study evaluated the disposition of a crystalloid and a colloid solution in 10 healthy cats under general anesthesia. Each cat was randomly assigned to receive either 20 mL/kg of a balanced isotonic crystalloid solution (PLA) or 5 mL/kg of 6% tetrastarch 130/0.4 solution (T-HES), administered over 15 minutes, in a 2-period, 2-treatment crossover design. Blood samples were collected, and urine output was measured during a 3-hour experimental period. Plasma dilution was calculated using serial hemoglobin concentrations and red blood cell count. Volume kinetics (distribution and elimination) of each fluid were determined using non-linear mixed effects pharmacokinetic modeling software. Data from a previous study with a similar methodology in healthy conscious cats were included in the population kinetic analysis, revealing anesthesia as a significant covariate for k21 (peripheral-to-central intercompartmental rate constant) for PLA and k10 (dilution-dependent first-order elimination rate constant) for T-HES. Cumulative urine output under general anesthesia was approximately 3.5 times lower for PLA and 2.5 times lower for T-HES compared to conscious cats. Overall, our data suggest that the elimination of PLA and T-HES is markedly reduced, and a bolus of PLA produces a short period of plasma expansion with the potential to cause significant peripheral fluid accumulation in cats during general anesthesia.

Objectives

Globally, the circulation of influenza and other seasonal respiratory viruses changed dramatically during the COVID-19 pandemic. This study aims to determine the trends of acute respiratory infections (ARIs) caused by SARS-CoV-2, influenza A, influenza B and respiratory syncytial viruses (RSVs) in patients presenting to hospitals in the Lao People’s Democratic Republic (PDR) (Laos).

Design

Prospective surveillance study.

Setting

Four provincial hospitals across Laos between March 2021 and July 2023.

Participants

Participants of all ages who met our case definition for an ARI (axillary temperature ≥37.5°C or history of fever AND cough or other respiratory symptoms/signs OR loss of smell and/or taste) presenting to the hospital less than 10 days after symptom onset were eligible to be enrolled in the study. Combined nasopharyngeal and throat swabs were tested for SARS-CoV-2, influenza A, influenza B and human RSV (hRSV) using probe-based real-time RT (Reverse transcription)-PCR assays.

Primary outcome measure

The proportion of patients in whom SARS-CoV-2, influenza A, influenza B and hRSV was detected.

Results

There were 4203 patients recruited, of whom 898 (21%) were children aged under 5 years. SARS-CoV-2 was detected in 16.9% of patients, followed by influenza A, influenza B and hRSV (8.4%, 7.2% and 4.7%, respectively). 98 patients (2.3%) were diagnosed with probable co-infection, with at least two viruses detected. After May 2022, the number of cases of influenza A, influenza B and hRSV increased rapidly. Six per cent of patients (263) had a quick Sequential Organ Failure Assessment score of ≥2, and 34 (0.8%) patients died, of whom 11 tested positive for a respiratory virus.

Conclusions

During the COVID-19 pandemic in Laos, few respiratory viruses were detected by passive surveillance until the relaxation of non-pharmaceutical interventions implemented for infection control. After restrictions were lifted, influenza A, influenza B and hRSV emerged rapidly, showing the importance of continuous surveillance.

Creating Colostomies for Sacral Pressure Ulcers: A Single‐Centre Retrospective Study

ABSTRACT

Faecal contamination of sacral pressure ulcers occurs frequently, so, theoretically, faecal diversion using colostomies is a useful procedure. We retrospectively analysed the data of adult patients for whom colostomies were created to enhance wound healing and compared patients with sacral pressure ulcers who received colostomies and those who did not during the same period. Patients' characteristics analysed included age, gender, comorbidities, WBC count, serum CRP level and microbial profile (before creating colostomy). Additionally, we examined whether the wound was closed, the recurrence rate after wound closure, and mortality outcomes. Regression analysis indicated that colostomy creation was associated with fewer species of gut microbiota cultured and lower rates of wound dehiscence after closure; no association was found between colostomy and mortality. Colostomies help promote wound healing of sacral pressure ulcers after closure by eradicating wound infection, and do not increase patients' mortality rates.

Objectives

Cohort studies of ageing and cognitive decline typically do not begin fielding comprehensive cognitive assessments until older adulthood. However, for identifying preventable dementia risk factors, there is strong value in beginning at earlier ages. The case is especially compelling in sub-Saharan Africa, where the number of older individuals is expected to triple in the next three decades, and where risk factors may operate more intensively at earlier ages. This study reports on the adaptation and validity of the Harmonised Cognitive Assessment Protocol (HCAP) approach in the Kenya Life Panel Survey (KLPS), collected among middle-aged respondents.

Design

To evaluate the validity of the HCAP approach in Kenya, this study assesses model fit statistics from confirmatory factor analyses (CFA) and tests measurement invariance by respondent characteristics.

Setting

Both rural and urban areas in Kenya.

Participants

A sample of n=5878 individuals from the KLPS, who have been surveyed regularly since they were schoolchildren in the 1990s. The HCAP assessment was administered in 2023 at an average age of 37 years (10–90 range 34 to 41).

Primary and secondary outcome measures

For each individual, the CFA generates a general cognitive performance score, and cognitive performance scores for five distinct domains, including memory, executive functioning, language, orientation to time and place, and visuospatial functioning.

Results

Fit of the models to the data was adequate for general cognitive performance (root mean squared error of approximation (RMSEA)=0.03; comparative fit index (CFI)=0.94; standardised root mean residual (SRMR)=0.05), language (RMSEA=0.02; CFI=0.95; SRMR=0.05) and good for memory (RMSEA=0.05; CFI=0.99; SRMR=0.02) and executive functioning (RMSEA=0.03; CFI=0.98; SRMR=0.03). The CFA indicate that the factor structure is consistent with findings from other countries and that reliability for the general cognitive performance score was high. Statistical models also suggest invariance at the scalar level for leading demographic (gender, age) and socioeconomic (education, occupational complexity) characteristics.

Conclusions

This study demonstrates that the cognitive functioning of mid-age Kenyans appears to be well captured by the adapted protocol. While there is a moderate decline in cognitive performance among older individuals, this relationship appears to be mediated by education, indicating that this KLPS HCAP provides a valuable baseline for studying future cognitive decline.

eHealth versus face-to-face support for remission of type 2 diabetes by calorie restriction (eHealth DIabetes remission Trial): study protocol for a non-inferiority parallel group randomised controlled trial

Por: Otten · J. · Tellström · A. · Schien · C. · Chninou · Y. · Lindholm · L. · Winkvist · A. · Liv · P. · Stomby · A.
Introduction

If a person is in diabetes remission, even if only for a short time, this reduces the risk of later diabetes complications and lowers healthcare costs. A recent study shows that long-term remission of type 2 diabetes can be achieved through calorie restriction using total diet replacement. However, this intervention involves support through face-to-face meetings every 2 to 4 weeks over a 2-year period, which is not feasible in routine care with limited resources. Therefore, we have developed an eHealth programme to help patients achieve diabetes remission through calorie restriction in a cost-effective manner. Our primary hypothesis is that an eHealth programme will be non-inferior to face-to-face meetings in helping patients with type 2 diabetes achieve remission through caloric restriction. Our second hypothesis is that eHealth support will be more cost-effective than face-to-face support.

Methods and analysis

The eHealth DIabetes remission Trial is a multicentre, two-arm, non-inferiority, open-label, randomised controlled parallel group trial with blinded endpoint assessment conducted at two centres in Sweden. The study duration is 2 years. People with type 2 diabetes (≤6 years duration) use total diet replacement (approximately 900 kcal/day) with the aim of losing 15 kg and achieving diabetes remission. Participants are randomly assigned to either the eHealth support group or the face-to-face support group. The treatment programme to achieve and maintain weight loss is the same in both groups, but the method of support differs between the groups. The primary outcome is haemoglobin A1c (HbA1c) after 1 year. The secondary outcome is HbA1c at 6 months and 2 years. Other important secondary outcomes are diabetes remission rate, body weight and cost-effectiveness. The latter is assessed using the incremental cost per quality-adjusted life-years gained.

Ethics and dissemination

The study was approved by the Swedish Ethical Review Authority (Dnr 2022-02242-01, 2023-03707-02). The results will be published in peer-reviewed scientific journals and discussed at national and international conferences and with patient organisations.

Characterizing temporal and global host innate immune responses against SARS-CoV-1 and -2 infection in pathologically relevant human lung epithelial cells

by Vivian Y. Tat, Aleksandra K. Drelich, Pinghan Huang, Kamil Khanipov, Jason C. Hsu, Steven G. Widen, Chien-Te Kent Tseng, George Golovko

Severe acute respiratory syndrome coronavirus-1 (SARS-CoV-1) and -2 (SARS-CoV-2) are beta-coronaviruses (β-CoVs) that have caused significant morbidity and mortality worldwide. Therefore, a better understanding of host responses to β-CoVs would provide insights into the pathogenesis of these viruses to identify potential targets for medical countermeasures. In this study, our objective is to use a systems biology approach to explore the magnitude and scope of innate immune responses triggered by SARS-CoV-1 and -2 infection over time in pathologically relevant human lung epithelial cells (Calu-3/2B4 cells). Total RNA extracted at 12, 24, and 48 hours after β-CoVs or mock infection of Calu-3/2B4 cells were subjected to RNA sequencing and functional enrichment analysis to select genes whose expressions were significantly modulated post-infection. The results demonstrate that SARS-CoV-1 and -2 stimulate similar yet distinct innate antiviral signaling pathways in pathologically relevant human lung epithelial cells. Furthermore, we found that many genes related to the viral life cycle, interferons, and interferon-stimulated genes (ISGs) were upregulated at multiple time points. Based on their profound modulation upon infection by SARS-CoV-1, SARS-CoV-2, and Omicron BA.1, four ISGs, i.e., bone marrow stromal cell antigen 2 (BST2), Z-DNA Binding Protein 1 (ZBP1), C-X-C Motif Chemokine Ligand 11 (CXCL11), and Interferon Induced Transmembrane Protein 1 (IFITM1), were identified as potential drug targets against β-CoVs. Our findings suggest that these genes affect both pathogens directly and indirectly through the innate immune response, making them potential targets for host-directed antivirals. Altogether, our results demonstrate that SARS-CoV-1 and SARS-CoV-2 infection induce differential effects on host innate immune responses.

Comparison between artificial dermis with split‐thickness skin graft and full‐thickness skin graft for reconstruction of joint‐involved burn wounds: A retrospective review from a tertiary burn centre

Abstract

We aimed to compare the scar quality and recovery rate of joint activity for patients with joint-involved burn injuries receiving either artificial dermis (AD) with split-thickness skin graft (STSG) or full-thickness skin graft (FTSG) for reconstruction. The primary outcomes were %skin graft (SG) take. Secondary outcomes included complications such as the infection rate and donor site morbidity, 12-month scar quality evaluated using the Vancouver scar scale (VSS), recovery rate of joint activity and incidence of scar contracture requiring further revision. Twenty-eight patients between 1 August 2021, and 1 August 2023, were enrolled. Twelve patients received AD-STSG while the other 16 patients underwent FTSG for reconstruction. The median %SG take was 95.0% (interquartile range [IQR] 6.3%) and 96.0% (IQR 10.0%) for the AD-STSG and FTSG groups (p = 0.71). The FTSG group had significantly better 12-month scar quality (median VSS 4.0 [IQR 1.3] vs. 6.0 [IQR1.5], p < 0.01) and recovery rate of joint activity (median 82.5% [IQT 15.0%] vs. 70.0% [IQR 7.5%], p < 0.01) compared with AD-STSG group. However, two patients in the FTSG group (12.5%) suffered partial wound dehiscence of the donor site, whereas no patients experienced donor site morbidity in the AD-STSG group (p = 0.49). The incidence of scar contracture requiring further revision was 25.0% (3/12) in the AD-STSG group and 12.5% (2/16) in the FTSG group (p = 0.62). In conclusion, AD-STSG could be an alternative treatment over FTSG for larger joint-involved burn wounds (>200 cm2) owing to lesser donor site morbidity with admissible cosmetic outcomes and functional recovery.

Clinical efficacy of crushed prednisolone and hydrocolloid powder in the primary treatment of peristomal pyoderma gangrenosum and correlation to in vitro drug release data

Abstract

We evaluated the primary application of crushed prednisolone combined with hydrocolloid powder for clinically diagnosed peristomal pyoderma gangrenosum (PPG). We present our data on this cohort and follow-up of our previous patients. Of the 23 patients who were commenced on this regime, 18 healed (78%). Twenty-two patients commenced on this regime as the primary treatment for their PPG, and for one, it was a rescue remedy after failed conventional therapy. Four patients with significant medical comorbidities failed to heal and one had their stomal reversal surgery before being fully healed. The proposed treatment regime for PPG is demonstrated to be effective, inexpensive and able to be managed in the patient's usual home environment. In vitro drug release analysis was undertaken, and data are presented to provide further insights into the efficacy of this regime.
