Authors: Lai Jia-Wen , Wang Charles C.N. , Chou Che-Yi 
Published: July 2024

Abstract
Background
Sodium-glucose transporter-2 inhibitors (SGLT-2i) are recommended for use in patients with type 2 diabetes comorbid atherosclerotic cardiovascular disease, heart failure, or chronic kidney disease. Limited reports are currently available for their use in dialysis patients. In an observational, retrospective follow-up study, we reported the clinical characteristics of chronic peritoneal dialysis (PD) patients on SGLT-2i.

Methods
We enrolled 50 diabetic chronic PD patients, and 11 continued SGLT-2i after PD treatment. We reported the patients’ ultrafiltration, HbA1c, urinary tract infection episodes, and venous CO2 during follow-up and compared the differences in these factors between patients with and without SGLT-2i.

Results
The mean age of the patients was 65 ± 15 years, and 16 (32%) patients were female. The age, gender, heart failure, and primary kidney disease were not different between patients with and without SGLT-2i at enrollment. In an average of 31 months follow-up, patients with SGLT-2i had higher ultrafiltration (1322 ± 200 ml/day vs. 985 ± 415 ml/day, p = 0.013), hemoglobin (11.2 ± 1.7 vs. 10.2 ± 1.7 g/dl), white blood cell count (9.2 ± 3.7 vs. 7.4 ± 2.1 109/L), and a lower venous CO2 (p = 0.036). The urine amount, the overall survival, the technical survival, and the chance of UTI were not different between patients with and without SGLT2i.

Conclusion
SGLT-2i may increase ultrafiltration volume and hemoglobin levels in chronic PD patients. SGLT-2i did not increase urinary tract infection but was linked to subclinical metabolic acidosis.

What was known
The effect of SGLT-2i in chronic PD patients is not clear?

This study adds
SGLT-2i is associated with increased ultrafiltration, hemoglobin, white blood cell counts, and a decreased CO2 in PD patient.

Potential impact
SGLT-2i may increase ultrafiltration in PD patients.

Abstract
Background
Adequate housing is a fundamental right and a social determinant of health. It also represents a historically contentious topic in Latin America. Migratory flows to Chile have become increasingly precarious in the past few years, limiting opportunities for adequate housing, with potential repercussions on the health of international migrants and the general population. This study aims to analyse adequate housing as a social determinant of health among international migrants and locals between 2013 and 2022 in Chile.

Methods
Observational cross-sectional study based on repeated versions of the nationally representative Socioeconomic Characterization Survey in Chile. Adequate housing indicators adapted from the United Nations Housing Rights Programme guidelines were analyzed with relation to individual health, distinguishing between the local and international migrant populations. Logistic regression models were fitted for housing indicators with migration as the main independent variable and for short-term and long-term healthcare needs in locals and immigrants with housing as the main dependent variables. Models were adjusted for sociodemographic variables and considered the complex sample design.

Results
Descriptive findings indicated higher availability of services and infrastructure among international migrants, and a disadvantage for habitability, location, and affordability by quintiles compared to locals. Logistic regression models, adjusting for demographic variables, revealed significant associations between migration status and overcrowding (OR 6.14, 2022), poor housing materiality (OR 5.65, 2022) and proximity to healthcare centres (OR 1.4, 2022) compared to locals. Experiencing hazardous situations consistently predicted short-term healthcare needs in both migrants (OR = 1.4, 2022) and locals (OR = 2.8, 2022). Overcrowding predicted both long and short-term healthcare needs among locals across the years and long term needs among migrants in 2013 and 2015.

Conclusions
We found significant inequities in adequate housing between migrant populations and locals in Chile, and some inequities among both populations based on structural socioeconomic deprivation. Experiencing hazardous situations emerged as a social determinant of health among international migrants in 2022, potentially suggesting growing challenges related to social exclusion in urban areas. However, limitations such as exclusion criteria of the survey and sample sizes for data on the migrant population potentially suggest that housing challenges and their impact on health are underestimated.
Anterior cervical corpectomy and fusion-derived adjacent segment disease managed via channel-repairing anterior endoscopic transcorporeal cervical discectomy: a case report
Authors: Qin Jianpu , Qian Hu , Xin Zhijun , Liu Guangyi , Ao Jun , Liao Wenbo 
Published: July 2024

Abstract
Background
Management of anterior cervical corpectomy and fusion (ACCF)-derived adjacent segment disease (ASD) represented a challenge facing the surgeons.

Methods
A 41-year man diagnosed as C3-4 level ASD derived from C5-level ACCF surgery 13 years ago was admitted to the hospital for numbness and pain in the right shoulder and upper limb. Percutaneous full-endoscopic anterior transcorporeal cervical discectomy (PEATCD) was performed, and pre- and postoperative clinical and imaging data were collected.

Results
The operation was completed within 70 min, and no clinical or radiological complication was reported. The visual analog scale (VAS) score decreased from preoperative 5 points to postoperative 1 point. Numbness was relieved postoperatively and disappeared completely at postoperative 3 months. Imaging data indicated sufficient spinal cord decompression, good channel repairing and cervical alignment.

Conclusions
Channel-repairing PEATCD was successfully performed to treat ACCF-derived ASD, nevertheless, the long-term efficacy remained tracing and further clinical trials were needed to validate its efficacy.
Does krill oil enhancing the new bone formation in orthopedically expanded median palatal suture in rat model? A micro-CT and immunohistochemical analysis
Authors: Simsek Doga , Gok Gulay Dumanli , Delipinar Sibel Demirci 
Published: July 2024

Abstract
Background
The purpose of this study was to assess the effects of systemically given krill oil (KO) on the development of new bone formation in the sutura palatina media following rapid maxillary expansion (RME).

Methods
28 4–5 week-old male Wistar albino rats were randomly divided into 4 groups: Control (C), Only Expansion (OE) (no supplement but undergoing expansion and retention), KE (supplemented during both the expansion and retention phases), Krill Oil Nursery Group (KN) (supplemented during the 40-day nursery phase as well as during the expansion and retention phases). A 5-day RME was followed by a 12-day retention period. All rats were euthanized simultaneously. Micro-computerized tomography (Micro-CT), hemotoxylen-eosin (H&E) staining, and immunohistochemical analysis were conducted. Kruskal-Wallis and Dunn tests with Bonferonni corrrection were applied (p < 0.05).

Results
Expansion and KO supplementation did not cause a statistically significant change in bone mineral density (BMD), bone volume fraction (BV/TV), spesific bone surface (BS/BV) and trabecular thickness (Tb.Th). While the expansion prosedure increased the trabecular seperation (Tb.Sp), KO supplemantation mitigated this effect. The KE group exhibited a statistically significantly increase in trabecular number (Tb.N) compared to the OE group. Although receptor activator of nuclear factor-kappa-Β ligand (RANKL)/osteoprotegerin (OPG) ratios did not show significant differences between groups, the KE and OE groups demonstrated the lowest and highest value, respectively. KE showed a reduced amount of tartrate-resistant acid phosphatase (TRAP) compared to the OE.

Conclusion
KO positively affected the architecture of the new bone formed in the mid-palatal suture. In this rat model of RME, results support the idea that administering of KO during the expansion period or beginning before the RME procedure may reduce relapse and enhance bone formation within the mid-palatal suture.

Published: July 2024

Abstract
Background
The death of a child is one of the most devastating events a family can face, resulting in significant physical and psychosocial morbidity. Bereavement support programs have been developed in high-income contexts to address this need. However, little is known about implementing bereavement programs in low-and middle-income countries (LMICs). Here, we describe the implementation of a bereavement program for parents whose children died due to cancer or other catastrophic illnesses.

Methods
We conducted a retrospective analysis to describe the implementation of a hospital-based End of Life (EoL) care and bereavement program. This program was developed in several stages, including an assessment of bereaved families, development program guidelines, staff training, piloting of the program, refinement, and standardization. The program was developed between 2019 and 2021 in a nonprofit, teaching hospital and referral center for southwestern Colombia.

Results
Several tools were developed as key components of the bereavement program: a virtual bereavement course; guidance for EoL and bereavement communication and care, memory making, and follow-up calls; a condolence letter template, and group support workshops. A total of 956 healthcare professionals were trained, 258 follow-up calls to bereaved parents were made, 150 individual psychological follow-ups to parents with complicated grief occurred, 79 condolence letters were sent, and 10 support group workshops were carried out. Challenges were identified and overcome, such as limited resources and staff, and cultural perceptions of death. In 2021, this program received an award by the hospital as the Best Strategy to Humanize Healthcare.

Conclusions
This study highlights the feasibility of developing and implementing EoL and bereavement care programs for parents and families within hospitals in LMICs. Lack of resources, staff, and training are some of the identified challenges to implementation. Utilizing methodological tools allows us to identify facilitator factors and deliverable outcomes of our EoL and bereavement program. This model provides a valuable framework for resource-limited settings.
Nurses’ perception of thirst in patients within palliative home care: a qualitative study
Authors: Lythell Caroline , Schaller Anne Söderlund , Jaarsma Tiny , Friedrichsen Maria 
Published: July 2024

Abstract
Background
Thirst is the body’s natural urge to replenish fluids in response to a deficiency in hydration. Patients at the end of life gradually lose their independence and reach a point where they become unable to express their needs and can no longer drink on their own. In palliative care, the main advice is to provide regular oral care to relieve symptoms such as dry mouth and thirst. However, according to previous studies the prevalence of thirst and dry mouth remains.

Aim
The aim of this study was to describe palliative care, nurses’ views and experiences of thirst in end-of-life care in specialist palliative care units.

Methods
A qualitative interview study with an inductive approach was conducted. Eighteen nurses working in six different specialist palliative care units in different hospitals in Sweden were interviewed. The interviews were transcribed and analysed with a content analysis approach according to Graneheim and Lundman.

Results
When nurses discuss thirst, they perceive thirst as a problem for the patient. This is attributable to various factors, including the patient breathing with an open mouth, a reduced level of awareness, and negligence on the part of the nursing staff. Signs of thirst are dry mouth, and frequently and intense sucking on the oral care stick during oral care. It also emerged that not all nurses perceived that dying patients experienced thirst. They believe that thirst is something that is reduced in the dying patient in the same way as hunger. The most important thing to them is to relieve the dry mouth by providing good oral care. Several issues, such as a lack of guidelines paired with the patient’s reduced consciousness and hence his/her lack of communication, make assessing thirst problematic.

Conclusion
Nurses have different thoughts and experiences about thirst, where some perceive patients as thirsty while others perceive them as having a dry mouth. Nurses expressed that both evidence and guidelines are lacking.

Abstract
Background
The aims of the present study were to investigate the incidence of nurses who suffered anxiety during the COVID-19 pandemic and to explore how expressive suppression influences the relationship between family function and anxiety.

Methods
This study used cross-sectional research and simple random sampling. A total of 300 questionnaires were distributed and 254 questionnaires were qualified after invalid questionnaires were proposed, thus a total of 254 female nurses from a tertiary hospital were included in this study. The measurement included General demographic questionnaires, the Self-Scale Anxiety, Scale (SAS), Emotion Regulation Strategies Questionnaire (ERQ), and Family Function Assessment (FAD). T-test, nonparametric Wilcoxon or Kruskal-Wallis test, χ2 test, Pearson or Spearman correlation analysis, multiple stepwise regression and bootstrap methods was performed to analyze the data.

Results
In this study, 22.4% of the nurses exhibited anxiety symptoms, with 17.7% eliciting mild anxiety symptoms, 4.3% showing moderate anxiety symptoms and 0.4% with severe anxiety symptoms. Family function and expressive suppression were positively associated with anxiety severity. And family function influenced anxiety among nurses via direct and indirect (Expressive suppression -mediated) pathways.

Conclusions
Expressive suppression partially mediated the influence of family function on anxiety symptom. To this end, nurse administrators should establish a robust mental health support system encompassing psychological counseling and emotional support groups. Furthermore, nurse administrators should consistently inquire about nurses’ family situations, encourage nurses to articulate their emotions and needs candidly, both within the domestic sphere and the workplace, while refraining from excessive self-repression.

Abstract
Background
The COVID-19 vaccination programme in South Africa was rolled out in February 2021 via five delivery channels- hospitals, primary healthcare (PHC), fixed, temporary, and mobile outreach channels. In this study, we estimated the financial and economic costs of the COVID-19 vaccination programme in the first year of roll out from February 2021 to January 2022 and one month prior, in one district of South Africa, the West Rand district.

Methods
Financial and economic costs were estimated from a public payer’s perspective using top-down and ingredient-based costing approaches. Data were collected on costs incurred at the national level and from the West Rand district. Total cost and cost per COVID-19 vaccine dose were estimated for each of the five delivery channels implemented in the district. In addition, we estimated vaccine delivery costs which we defined as total cost exclusive of vaccine procurement costs.

Results
Total financial and economic costs were estimated at US$8.5 million and US$12 million, respectively; with a corresponding cost per dose of US$15.31 (financial) and US$21.85 (economic). The two biggest total cost drivers were vaccine procurement which contributed 73% and 51% to total financial and economic costs respectively, and staff time which contributed 10% and 36% to total financial and economic costs, respectively. Total vaccine delivery costs were estimated at US$2.1 million (financial) and US$5.7 million (economic); and the corresponding cost per dose at US$3.84 (financial) and US$10.38 (economic). Vaccine delivery cost per dose (financial/economic) was estimated at US$2.93/12.84 and US$2.45/5.99 in hospitals and PHCs, respectively, and at US$7.34/20.29, US$3.96/11.89 and US$24.81/28.76 in fixed, temporary and mobile outreach sites, respectively. Staff time was the biggest economic cost driver for vaccine delivery in PHCs and hospitals while per diems and staff time were the biggest economic cost drivers for vaccine delivery in the three outreach delivery channels.

Conclusion
This study offers insights for budgeting and planning of COVID-19 vaccine delivery in South Africa’s public healthcare system. It also provides input for cost-effectiveness analyses to guide future strategies for maximizing vaccination coverage in the country.
Understanding patient perspectives on digital therapeutics and its platform for insomnia: insights from focused group interviews
Authors: Kim Jinhyun , Park Kyung Mee , Lee Suonaa , Park Sooji , Hong Minji , Shin Jaeyong , Lee Eun 
Published: July 2024

Abstract
Background
Digital therapeutics (DTx) is a treatment option that uses computer software to provide evidence-based interventions for medical disorders. DTx platforms are digital services that facilitate interactions among stakeholders of DTx treatment within a standardized structure. However, there is still a lack of overall awareness regarding the effectiveness and usage of DTx and DTx platforms. This study aimed to investigate insomnia patients’ recognition, thoughts, feelings, and demands for conventional treatments versus DTx for insomnia.

Methods
Nine participants, aged 19–50 years, who had experience with professional medical interventions for insomnia, were recruited through purposive sampling. Two online focus group interviews, each lasting 1.5 h, were conducted. The interview questions focused on difficulties encountered during conventional treatment, inadequate recognition of DTx, and concerns and demands regarding DTx and its platform. The data were analyzed using thematic analysis.

Results
The participants reported subjective difficulties associated with receiving conventional treatment, including concerns about drug side effects and dependence, social stigma, and lack of perceived necessity for treatment. They expressed concerns about DTx, such as cost-effectiveness, evidence on efficacy, and concerns about breach of personal information. Additionally, their demands included convenience of use, reduction in social stigma related to the use of DTx, compatibility of DTx with other healthcare systems, and enhanced communication with healthcare providers when using DTx platforms.

Conclusions
The focus group highlighted the need for increased awareness, demonstrated efficacy, cost-effectiveness, cybersecurity measures, and accessibility of insomnia DTx and its platforms. Tailored approaches considering patient characteristics are crucial for widespread adoption of insomnia DTx and its platforms.

Abstract
Background
Salmonid species have followed markedly divergent evolutionary trajectories in their interactions with sea lice. While sea lice parasitism poses significant economic, environmental, and animal welfare challenges for Atlantic salmon (Salmo salar) aquaculture, coho salmon (Oncorhynchus kisutch) exhibit near-complete resistance to sea lice, achieved through a potent epithelial hyperplasia response leading to rapid louse detachment. The molecular mechanisms underlying these divergent responses to sea lice are unknown.

Results
We characterized the cellular and molecular responses of Atlantic salmon and coho salmon to sea lice using single-nuclei RNA sequencing. Juvenile fish were exposed to copepodid sea lice (Lepeophtheirus salmonis), and lice-attached pelvic fin and skin samples were collected 12 h, 24 h, 36 h, 48 h, and 60 h after exposure, along with control samples. Comparative analysis of control and treatment samples revealed an immune and wound-healing response that was common to both species, but attenuated in Atlantic salmon, potentially reflecting greater sea louse immunomodulation. Our results revealed unique but complementary roles of three layers of keratinocytes in the epithelial hyperplasia response leading to rapid sea lice rejection in coho salmon. Our results suggest that basal keratinocytes direct the expansion and mobility of intermediate and, especially, superficial keratinocytes, which eventually encapsulate the parasite.

Conclusions
Our results highlight the key role of keratinocytes in coho salmon’s sea lice resistance and the diverged biological response of the two salmonid host species when interacting with this parasite. This study has identified key pathways and candidate genes that could be manipulated using various biotechnological solutions to improve Atlantic salmon sea lice resistance.
