Nursing home geriatric rehabilitation care and interprofessional collaboration; a practice-based study
Authors: Drenth Hans , Krijnen Wim , van der Weerd Lourens , Reinders Jan Jaap , Hobbelen Hans
Published: September 2023

Background

Frailty and multimorbidity are common among patients in geriatric rehabilitation care (GRC). Proper care of these patients involves multiple professionals which requires optimal interprofessional collaboration to provide the best possible support. Interprofessional collaboration (IPC) goes beyond multi-professional collaboration. It requires professionals to think beyond the expertise of their own discipline and work on joint outcomes in which the patient is actively involved. This study describes the development of the GRC teams of an elderly care organization towards the IPC.

Methods

Mixed method pre-post study of 15 months. The interprofessional training program comprised team trainings, webinars, and online team sessions. Data was aggregated by administering the Extended Professional Identity Scale (EPIS) and QuickScan Interprofessional Collaboration (QS) measurements to GRC staff and by observations of the multi-professional team consultation (MPC) meetings of six GRC teams of an organization for elderly care in Drachten and Dokkum in the Netherlands. ADL independence (Barthel Index) and number of inpatient days were analyzed before and after the project.

Results

Pretest healthcare professional response was 106, patients for analyses was 181; posttest response was 84, patients was 170. The EPIS shows improvement on “interprofessional belonging” (P = .001, 95%CI: 0.57–2.21), “interprofessional commitment” (P = .027, 95%CI: 0.12–1.90), and overall “interprofessional identity” (P = .013, 95%CI: 0.62 − 5.20). On the QS, all domains improved; “shared values” (P = .009, 95%CI: 0.07 − 0.47), “context” (P = .005, 95%CI: 0.08 − 0.44), “structure & organization” (P = .001, 95%CI: 0.14 − 0.56), “group dynamics & interaction” (P < .001, 95%CI: 0.18 − 0.58), and “entrepreneurship & management” (P = .039, 95%CI: 0.01 − 0.48). A qualitative analysis of the reflection responses and MPC observations indicate a shift from multi-professional to more IPC. Differences in ADL over time were not statistically significant. The mean number of inpatient days was reduced by 11.8 (P < .001, 95%CI: -17.34 - − 6.31) days.

Conclusions

Within the GRC teams, there was a shift observed to more IPC and better representation of the patient’s wishes and needs. ADL independence did not change, yet we found a statistically significant decrease in the number of inpatient days. The basis for IPC was well established, however, it remains necessary that the teams continue to develop and invest in the collaboration with each other and the patient to further improve it.

Published: September 2023

Background

Rurality is fraught with numerous difficulties including a lack of advanced health facilities to provide health services, and an absence of specialist cancer services, and qualified personnel, among others. These factors exacerbate the challenges of elderly patients diagnosed with cancer and further pose limitations to activities/instrumental activities of daily living. Yet, there is limited scholarship on the strains that affect elderly patients diagnosed with cancer and the resources that helps them to overcome them. This study explores the strains, resources, and coping strategies of elderly patients diagnosed with cancer and undergoing treatment in rural Ghana.

Methods

An exploratory, descriptive qualitative design was adopted. Purposive sampling was used to recruit 20 individuals to participate in in-depth interviews. The collected data was analysed inductively using Collaizi’s framework. QSR NVivo-12 was used in managing the data.

Results

The results were grouped into two main categories, namely: strains and resources. Within the category of strains, three main themes with their corresponding sub-themes emerged: cancer-related strains (systemic side effects from treatment, altered physical appearance and body image, and experience of pain), elderly strains (altered functional ability, limited social interactions and participation, psycho-emotional reactions, limited/restricted economic participation, and financial strains), and health system strains (negative attitude and insensitive communication, delay in diagnosis, lack of geriatric oncology care, lack of community-based specialist cancer centre and long travel distance to access care, and limited availability of essential cancer medicines and other radiations services). Four types of resources were available to cancer patients: personal resources, family resources, community resources, and healthcare systems resources.

Conclusion

In conclusion, elderly patients diagnosed with cancer experience physical, economic, psychological, and emotional strains that threaten their health and well-being. However, they are able to leverage family, community, and health system-related resources to navigate through the strains. There is, therefore, a need to expand advanced health facilities with geriatric oncology units and specialists to improve access to cancer care in rural areas. The government needs to assist elderly persons with costs associated with their diagnosis and treatment through the expansion of the National Health Insurance Scheme to include this as part of the benefits package.
Receiving hemodialysis in Hispanic ethnic dense communities is associated with better adherence and outcomes among young patients: a retrospective analysis of the Dialysis Outcomes and Practice Patterns Study
Authors: April-Sanders Ayana K. , Karaboyas Angelo , Yunes Milagros , Norris Keith C. , Dominguez Mary , Kim Ryung S. , Isasi Carmen R. , Golestaneh Ladan
Published: September 2023

Background

Hispanic ethnic density (HED) is a marker of better health outcomes among Hispanic patients with chronic disease. It is unclear whether community HED is associated with mortality risk among ethnically diverse patients receiving maintenance hemodialysis.

Methods

A retrospective analysis of patients in the United States cohort of the Dialysis Outcomes and Practice Patterns Study (DOPPS) database (2011–2015) was conducted (n = 4226). DOPPS data was linked to the American Community Survey database by dialysis facility zip code to obtain % Hispanic residents (HED). One way ANOVA and Kruskal Wallis tests were used to estimate the association between tertiles of HED with individual demographic, clinical and adherence characteristics, and facility and community attributes. Multivariable Cox proportional hazards models were used to estimate the mortality hazard ratio (HR) and 95% CIs by tertile of HED, stratified by age; a sandwich estimator was used to account for facility clustering.

Results

Patients dialyzing in facilities located in the highest HED tertile communities were younger (61.4 vs. 64.4 years), more commonly non-White (62.4% vs. 22.1%), had fewer comorbidities, longer dialysis vintage, and were more adherent to dialysis treatment, but had fewer minutes of dialysis prescribed than those in the lowest tertile. Dialyzing in the highest HED tertile was associated with lower hazard of mortality (HR, 0.86; 95% CI, 0.72-1.00), but this association attenuated with the addition of individual race/ethnicity (HR, 0.92; 95% CI, 0.78–1.09). In multivariable age-stratified analyses, those younger than 64 showed a lower hazard for mortality in the highest (vs. lowest) HED tertile (HR, 0.66; 95% CI, 0.49–0.90). Null associations were observed among patients ≥ 64 years.

Conclusions

Treating in communities with greater HED and racial/ethnic integration was associated with lower mortality among younger patients which points to neighborhood context and social cohesion as potential drivers of improved survival outcomes for patients receiving hemodialysis.
Clinical application of real-time PET/CT guided targeted retroperitoneal masses biopsy in diagnosing malignant tumors
Authors: Li Xiaomin , Zhang Wanchun
Published: September 2023

Objective

To explore the feasibility, safety, and clinical application value based on the fusion image of 18 F-FDG PET/CT, for guiding retroperitoneal puncture biopsy technology and to determine the diagnosis of retroperitoneal masses in diagnosing malignant tumors.

Methods

From March 2019 to January 2023, 42 patients underwent 18 F-FDG PET/CT imaging and were found to have retroperitoneal lesions that required definite diagnosis; 22 were male, 20 were female, and the average age was(59.17 ± 13.23) years. According to the fused 18 F-FDG PET/CT tomographic image, the target point with the highest metabolic activity, the safest, and expected maximum sample size was selected. CT scans were acquired with the same machine and fused with 18 F-FDG PET, guiding the puncture biopsy needle to approach the expected target zone, enabling timely delivery of pathological and immunohistochemical examination of the biopsy. Success rate, total examination time, biopsy operation time, complications, CT radiation dose, pathological, and immunohistochemical results were recorded.

Results

All 42 patients were sampled successfully with the successful rate being 100%. The site of sampling of 42 patients accurately targeted the highest metabolic activity, the safest, and the expected maximum sample size. All 42 patients received clear diagnosis (25 cases of malignant tumors and cases of 17 benign tissues). 15 cases of patients had a change in clinical diagnosis, accounting for 35.7% of all patients, and affecting subsequent treatment plans. The average total examination time for patients was (41.3 ± 7.3) minutes, and the biopsy operation time was (29.1 ± 8.7) minutes. The effective radiation dose generated by the entire examination generated by CT guidance was (2.0 ± 0.5) mSv; no severe complications occurred in the patients.

Conclusion

Real-time-guided retroperitoneal puncture biopsy based on 18 F-FDG PET/CT fusion image is safe, accurate, and feasible, and can provide patients of retroperitoneal mass with clear pathological diagnosis and immunohistochemical evaluation.

Authors: Zhu Hui-Ping , Qi Han , Liu Xiao-Hui , Liu Kuo , Li Bing-Xiao , Wen Fu-Yuan , Xie Yun-Yi , Zhang Ling
Published: September 2023

Background

Disability was a major public health problem in China. However, the prevalence of disabilities in community-dwelling adults and their relationships to chronic physical conditions were unclear. We aimed to estimate the prevalence of disabilities and associated factors among a large community-based cohort in China.

Methods

Participants who were local permanent residents aged 18 years or above and completed the disability assessments were selected from the Cohort study on Chronic Disease of Communities Natural Population in Beijing, Tianjin and Hebei (CHCN-BTH) from 2017 to 2019. Disability was assessed using five questions about impairments and activity limitations based on the International Classification of Functioning (ICF), Disability and Health. Univariate, multivariate and multilevel logistic regressions were conducted to estimate the associations between disabilities and associated factors.

Results

Totally, 12,871 community-dwelling adults completed the survey. Among of them, 12.9% (95% CI: 12.3%-13.5%) reported having any disability. The prevalence of any disability was significantly higher in participants who were older age, widowed, retired and smokers, had higher BMI, average monthly income < 5000 RMB, lower education level, lower physical exercise frequency and heavy physical labor. Multilevel logistic regressions showed that there were significant associations between disabilities with chronic physical conditions, especially in the vision impairment with lower back pain, and hearing impairment as well as difficulty walking without special equipment with injuries.

Conclusions

Many Chinese adults suffered from disabilities. Sustained efforts should be made to develop specific population-based health promotion and prevention programs for disabilities in China.

Food-related worry and food bank use during the COVID-19 pandemic in Canada: results from a nationally representative multi-round study
Authors: Daly Zachary , Black Jennifer , McAuliffe Corey , Jenkins Emily
Published: September 2023

Background

Early in the COVID-19 pandemic, nearly one in five adults in Canada worried about having enough food to meet their household’s needs. Relatedly, throughout the pandemic, public messaging repeatedly urged Canadians to support food charities, including food banks. Yet few studies have examined food bank usage during the pandemic or whether food charities were widely used by Canadians worried about food access.

Methods

This study draws on four rounds of nationally representative surveying conducted during the COVID-19 pandemic between May 2020 and December 2021 among adults 18 years and older living in Canada. Descriptive statistics were used to examine rates of food-related worry during all four survey rounds. Data from the fourth survey round, collected in December 2021, were used to explore use of food-based community programs since the onset of the pandemic, including food banks. Logistic regression analyses were used to examine differences in socio-demographic and health-related characteristics between adults who did and did not report accessing food banks before and after adjusting for household income.

Results

Across survey rounds (n = 12,091), more than one in seven participants reported stress or worry related to having enough food to meet their household’s basic needs in the previous two weeks. Yet, by December 2021, fewer than 4% of participants reported ever accessing a food bank during the pandemic. Younger age, living with a child, financial concerns due to the pandemic, two different measures of food worry, pre-existing mental health conditions, disability, LGBT2Q + identity, and racialized or Indigenous identity, were each statistically significantly associated with higher odds of using food banks even when controlling for household income.

Conclusions

Despite persistently high rates of food-related worry in 2020 and 2021 in Canada, relatively few adults reported accessing food banks or other charity-based community food programs. While respondents facing social, financial, and health-related inequities and reporting food worry were more likely to use food banks, most respondents did not report food bank use, regardless of financial or demographic circumstances or experiences of food worry. Findings align with previous research indicating that more adequate and comprehensive supports are needed to alleviate food-related-worry in Canada.

Published: September 2023

Background

Previous studies have investigated the association between cardiometabolic risk factors and cardiovascular disease (CVD), but evidence of the attributable burden of individual and combined cardiometabolic risk factors for CVD and mortality is limited. We aimed to investigate and quantify the associations and population attributable fraction (PAF) of cardiometabolic risk factors on CVD and all-cause mortality, and calculate the loss of CVD-free years and years of life lost in relation to the presence of cardiometabolic risk factors.

Methods

Twenty-two thousand five hundred ninety-six participants aged ≥ 35 without CVD at baseline were included between October 2012 and December 2015. The outcomes were the composite of fatal and nonfatal CVD events and all-cause mortality, which were followed up in 2018 and 2019 and ascertained by hospital records and death certificates. Cox regression was applied to evaluate the association of individual and combined cardiometabolic risk factors (including hypertension, diabetes and high low-density lipoprotein cholesterol (LDL-C)) with CVD risk and all-cause mortality. We also described the PAF for CVD and reductions in CVD-free years and life expectancy associated with different combination of cardiometabolic conditions.

Results

During the 4.92 years of follow-up, we detected 991 CVD events and 1126 deaths. Hazard ratio were 1.59 (95% confidential interval (CI) 1.37–1.85), 1.82 (95%CI 1.49–2.24) and 2.97 (95%CI 1.85–4.75) for CVD and 1.38 (95%CI 1.20–1.58), 1.66 (95%CI 1.37–2.02) and 2.97 (95%CI 1.88–4.69) for all-cause mortality, respectively, in participants with one, two or three cardiometabolic risk factors compared with participants without diabetes, hypertension, and high LDL-C. 21.48% of CVD and 15.38% of all-cause mortality were attributable to the combined effect of diabetes and hypertension. Participants aged between 40 and 60 years old, with three cardiometabolic disorders, had approximately 4.3-year reductions life expectancy compared with participants without any abnormalities of cardiometabolic disorders.

Conclusions

Cardiometabolic risk factors were associated with a multiplicative risk of CVD incidence and all-cause mortality, highlighting the importance of comprehensive management for hypertension, diabetes and dyslipidemia in the prevention of CVD.
Evaluation of different decontamination procedures on bond strength to sound and caries affected dentin using “no-wait” universal adhesive
Authors: Moharam Lamiaa M , Salem Haidy N , Khadr Sherif , Abdou Ahmed
Published: September 2023

Background

Current study aimed to evaluate the effect of different decontamination procedures on micro-shear bond strength (μSBS) of sound (SoD) and caries-affected dentin (CAD) of two universal adhesives after blood-saliva contamination.

Methods

One hundred and eighty bovine anterior teeth were prepared and allocated into the respective groups according to tested dentin substrates [SoD, CAD], universal adhesives [Clearfil Bond Universal Quick (UBQ), All-Bond-Universal (ABU)], adhesive contamination stage [none, contamination before and after adhesives light-curing], and according to decontamination procedures [no decontamination, water rinsing, adhesive rebond, Ethylenediaminetetraacetic acid (ETDA) and chlorhexidine (CHX) application]. Universal adhesives were applied according to manufacturer instructions in self-etch (SE) bonding mode. Four composite microrods were built for each tooth. Specimens were kept in distilled water for 24 hours at 37°C before testing μSBS. Four-way ANOVA and Tukey HSD tests were used for data analysis.

Results

A statistically significant difference between contamination stages of both universal adhesives at different decontamination procedures for SoD and CAD. Highest μSBS was recorded for UBQ control group at SoD, while the least was recorded for light-cured ABU upon water rinsing decontamination procedure of CAD.

Conclusions

Proper cavity isolation is mandatory to avoid possible contamination which can dramatically affect μSBS. CHX is a potent cavity decontaminant that can restore different dentin substrates bond strength. EDTA presents a promising substitute. UBQ adhesive showed better bonding performance than ABU to both dentin substrates. Application of regular cavity decontamination approaches is highly advised in daily practice to avoid possible detrimental effect of accidental cavity contamination.
Comparative analysis of anchorage strength and histomorphometric changes after implantation of miniscrews in adults and adolescents: an experimental study in Beagles
Authors: Zhao Yi , Jia TingTing , Wang Zhiqiang
Published: September 2023

Objectives

This study aimed to explore the differences in anchorage strength and histomorphometric changes in orthodontic miniscrews between adult and adolescent beagles.

Material and method

Six adult beagles and six young beagles were used as experimental subjects, and eight miniscrews were symmetrically placed in the posterior mandible of each dog. Measurement of the displacement (mm) of two adjacent miniscrews after load application was performed to compare the anchorage strength between the adult and adolescent groups. Three intravital bone fluorochromes (oxytetracycline, calcein green, xylenol orange) were administered postoperatively to mark the active bone-forming surface. Subsequently, the mineral apposition rate and bone-implant contact ratio were measured for dynamic and static histomorphometry. Finally, the expression levels of the RANKL/OPG ratio were evaluated by immunohistochemistry.

Results

The average displacement of miniscrews in the adult group was significantly less than that in the adolescent group after load application. For histomorphometry analysis, the mineral exposure rate in the adolescent group was higher than that in the adult group with or without force application. In addition, more fractures and new bone formation but deceased bone-implant contact ratios were observed in the adolescent group than in the adult group. The ratio of RANKL/OPG expression increased more in the adolescent group than in the adult group.

Conclusion

Miniscrews do not remain in the same position as skeletal anchors, and the amount of displacement was higher in adolescent group than that in adult group, reflecting the weaker anchorage strength of miniscrews in adolescents due to the higher bone turnover rate and active bone remodelling. Therefore, it is feasible to apply orthodontic loading to the miniscrews in adult patients earlier, even immediately, but it is recommended to wait a period for the adolescents.
Development and feasibility of an oral health e-learning program for long-term Japanese overseas workers: a pilot randomized controlled trial
Authors: Sasayama Kiriko , Momoi Yasuko , Gilmour Stuart , Ota Erika
Published: September 2023

Background

This study aimed to assess the feasibility and acceptability of an oral health self-care e-learning intervention for overseas workers as well as the research procedures for a future controlled trial.

Methods

We randomly allocated participants to either the intervention (n = 48) or control (n = 51) group. The intervention group received a standardized leaflet plus a theory-based oral health e-learning program. The control group received only the standardized leaflet. We assessed health behaviour related to fluoride toothpaste use, oral care knowledge, motivation, oral care self-efficacy, and oral health related quality of life (QoL). Chi-square and t test analyses were performed to make comparisons between the two groups. To evaluate the research process, participants in the intervention group were asked open-ended questions to assess the acceptability and feasibility of the research procedures in practice.

Results

A total of 82 participants (Intervention = 36, Control = 46) were included in the analysis. The dropout rate was 17.2%. The modal time taken to complete the e-learning intervention was more than 30 min (33.3%). Of the 36 respondents in the intervention group, 27 (70.4%) said that the e-learning intervention had changed their behaviour. At the three months follow-up, oral care knowledge alone was improved in the e-learning group.

Conclusion

This pilot study provides evidence that the theory-based self-care for oral health e-learning intervention is feasible in overseas workers. Next, this feasible and acceptable pilot study should be used with an appropriate sample size in a randomized controlled trial.

Participatory development of a manual for the implementation of diversity-sensitive palliative and hospice care in Germany: a mixed-methods study protocol
Authors: Erdsiek Fabian , Yılmaz-Aslan Yüce , Brzoska Patrick
Published: September 2023

Background

The diversity of the population is associated with different needs and expectations towards palliative and hospice care. Current approaches available in Germany generally fall short in addressing the role of diversity and intersectionality in this health care setting and healthcare facilities struggle with organizational difficulties and missing information on how to implement corresponding diversity-sensitive measures. The present study aims to develop a hands-on manual that enables providers of hospice and palliative care to implement measures and strategies for diversity-sensitive care, while taking into account the perspective of healthcare users and explicitly including vulnerable and minority patient groups.

Methods

A participatory approach is used to co-create the aforementioned manual using an explanatory sequential mixed-methods design. First, based on a systematic analysis of existing measures, an initial draft of the manual will be developed. Subsequently, an online survey will be conducted among all hospice and palliative care providers in Germany (n = 2,823). Based on the results of the survey, 12 to 15 qualitative problem-centered interviews will be conducted with employees of selected providers who took part in the survey. Results of the survey and the qualitative interviews will be integrated and analyzed. In parallel to the development and research process, a comprehensive dissemination strategy will be developed.

Discussion

The manual will assist providers of palliative and hospice care in determining goals, needs, and available resources in order to utilize patient-centered and diversity-sensitive measures to meet a wide range of expectations. It can also be informative for providers in other countries. The participatory co-development approach ensures the practical relevance of the manual, while the mixed-methods design allows for targeted input on the manual’s usability, acceptance, and viability as a supportive tool.
Filling gaps in experiences religious understanding of people living with cancer in palliative care: a phenomenological qualitative study
Authors: Silva Hellen Luiza Meireles , Valério Pedro Henrique Martins , Barreira Cristiano Roque Antunes , Peria Fernanda Maris
Published: September 2023

Background

According to a phenomenology of contemporary religion, the analysis of religious experiences finds that they are part of an individual’s search for something powerful that overcomes him seeking not only a need, but the meaning of all existence. The present study aims to contribute to a deeper understanding of the religious experiences of people living with cancer in palliative care (PC) and fill gaps in access to experience, with regard to how it was properly lived.

Methods

A qualitative, phenomenological, cross-sectional study was conducted with 14 people living with cancer undergoing PC at two outpatient clinics of a public hospital. The experiences were accessed through in-depth interviews and the results were analysed according to the principles of classical phenomenology.

Results

The patients confidently surrendered to the divine, attributing to it the power of continuity of life or not, which sustained them and launched them into horizons of hope, directing them to possibilities of achieving meaning in life, which it fed back their faith and to continue living, opening them up to an intense perception of the value of life.

Conclusions

The religious positions of confident surrender to the divine, to his will and a belief in his intervention, regardless of the outcome, opened possibilities to patients for the belief in the continuity of life by the power of faith. This position allowed the patients in this study to visualize achievements in the present and in the future, opening a horizon of hope, meaning and value of living. This study showed how this elements are presented and sustained, providing subsidies to health professionals seeking to provide more holistic care.
Safety and efficacy of P2Et extract from Caesalpinia spinosa in breast cancer patients: study protocol for a randomized double blind phase II clinical trial (CS003-BC)
Authors: Ballesteros-Ramírez Ricardo , Pinilla Paola , Sanchéz Jesús , Torregrosa Lilian , Aschner Pablo , Urueña Claudia , Fiorentino Susana
Published: September 2023

Background

Chemotherapy in breast cancer is effective but can generate significant toxicity and lead to tumor resistance. Joint treatment with standardized plant extracts can be an alternative to improve the response and allow an effective activation of the antitumor immune response that favors recovery in the short and long term. The P2Et extract of Caesalpinia spinosa presents antitumor activity in cells and animal models of breast cancer, improves the tumor microenvironment, and induces activation of the specific immune response against the tumor and is synergistic when used together with anthracyclines, which makes it a good candidate for evaluation in patients.

Methods

Conducted at a single center, this phase II study is a randomized, double-blind, placebo-controlled trial aimed at assessing the safety and efficacy of P2Et extract in patients diagnosed with stage II and III breast cancer, who are eligible for neoadjuvant treatment. The study aims to determine the safety profile at the previously established optimal biological dose from phase I trial while investigating various efficacy outcomes. These outcomes include improvements in quality of life, immunomodulation, metabolic profile, microbiome, as well as clinical indicators such as tumor reduction, disease-free survival, and pathological response, assessed at different stages of the treatment regimen.

Discussion

Treatment with the P2Et extract in breast cancer patients is hypothesized to enhance overall well-being, positively influencing their quality of life, while also triggering an antitumor immune response and enhancing immune infiltration. These combined effects have the potential to contribute to improved long-term survival outcomes for patients receiving the phytomedicine alongside neoadjuvant chemotherapy treatment.

Isolation, characterization and antimicrobial resistance of Yersinia enterocolitica from Polish cattle and their carcasses
Authors: Łada Piotr , Kończyk-Kmiecik Klaudia , Bancerz-Kisiel Agata
Published: September 2023

Background

Yersinia enterocolitica is a heterogeneous bacterial species that has been divided into six biotypes and more than 70 serotypes. Each year, the European Food Safety Authority classifies yersiniosis caused by Y. enterocolitica as one of the most important zoonotic diseases. The prevalence of Y. enterocolitica in cattle has not been thoroughly analyzed in Poland, and beef and bovine carcasses contaminated with antimicrobial resistant Y. enterocolitica pose a health risk for both, farm workers and consumers. Therefore, the aim of this study was to evaluate the prevalence of Y. enterocolitica in cattle and to determine the antimicrobial susceptibility of the isolated strains.

Results

A total of 1020 samples were analyzed, including 660 rectal swabs collected from live cattle and 360 swabs from cold-stored beef carcasses. The results of this study indicate that Y. enterocolitica was isolated from three of the 15 examined cattle herds and the prevalence within these herds ranged from 0% to nearly 32%. Y. enterocolitica was isolated from 14.7% of the examined heifers, 7.4% of calves and 5.5% of adult cows. More than 65% of the strains were isolated from cold enrichment. The strains isolated from live cattle tested positive for the ystB gene, while ail and ystA genes were not found. Most of the isolated strains belonged to bioserotype 1A/NT. The majority of the isolated strains were resistant to ampicillin, cefalexin and amoxicillin with clavulanic acid, however these are expected phenotypes for Y. enterocolitica.

Conclusions

The results of this study indicate that Y. enterocolitica is present in cattle herds in Poland. The strains isolated from live cattle were ystB-positive, most of them belonged to bioserotype 1A/NT. The prevalence of Y. enterocolitica strains was generally low in cold-stored beef carcasses.
Aldosterone-progesterone relationship in sexually intact Chihuahua bitches
Authors: Galizzi Alberto , Dossi Greta , Borromeo Vitaliano , Pocar Paola , Groppetti Debora , Locatelli Chiara
Published: September 2023

Background

Aldosterone represents an important target of heart failure therapy and may be a valuable indicator of the renin-angiotensin-aldosterone system activity. However, its assessment might be challenging because of the effect of individual factors. In a recent study, intact female dogs showed the highest value of urinary aldosterone-to-creatinine ratio (UAldo:C) compared to other sex categories. In humans and rodents, an influence of progesterone has been reported by several studies. To our knowledge, the relationship between aldosterone and progesterone has not yet been investigated in dogs. The aim of this prospective study was to investigate this relationship in sexually intact Chihuahua females, measuring both hormones twice in the same bitch, that is in anoestrus when progesterone concentrations are baseline and in dioestrus when they are high.

Results

The study population consisted of 14 sexually intact Chihuahua bitches. Serum progesterone (34.06 (21.17–44.90) vs. 0.19 [0.13–0.38] ng/ml; P < 0.001) and urinary aldosterone (9886.98 ± 5735.22 vs. 5005.72 ± 2127.73 pg/ml; P = 0.01) were significantly higher in dioestrus compared to anoestrous. Urinary aldosterone-to-creatinine ratio was higher in dioestrus compared to anoestrus (4.16 [3.17–6.80] vs. 3.39 ± 1.64 µg/g), but it did not reach the statistical significance (P = 0.056). Serum progesterone showed a moderate positive correlation with urinary aldosterone (ρ = 0.638, P < 0.001) and UAldo:C (ρ = 0.516, P = 0.005).

Conclusions

The results of the present study suggest the existence of a progesterone-aldosterone relationship in canine species, indicating that sex and phase of reproductive cycle should be taken into account when interpreting aldosterone concentrations. Further studies are needed to confirm these results on a larger canine population and to identify the underlying mechanisms in this species.

Published: September 2023

Background

Gastric cancer (GC) is one of the most common malignancies, affected by several genetic loci in the clinical phenotype. This study aimed to determine the association between PTGER4 and PRKAA1 gene polymorphisms and the risk of GC.

Methods

A total of 509 GC patients and 507 age and sex-matched healthy controls were recruited to explore the association between PTGER4 and PRKAA1 genetic polymorphisms and GC susceptibility. Logistic regression analysis was used to study the correlation between these SNPs and GC, with odd ratio (OR) and 95% confidence interval (CI) as indicators. Multifactor dimensionality reduction was utilized to analyze the genetic relationships among SNPs. was conducted to predict gene expression, the impact of SNPs on gene expression, and the signaling pathways involved in PTGER4 and PRKAA1.

Results

Overall, rs10036575 in PTGER4 (OR = 0.82, p = 0.029), rs10074991 (OR = 0.82, p = 0.024) and rs13361707 (OR = 0.82, p = 0.030) in PRKAA1 were associated with susceptibility to GC. Stratification analysis revealed that the effects of these SNPs in PTGER4 and PRKAA1 on GC susceptibility were dependent on smoking and were associated with a reduced risk of adenocarcinoma (p < 0.05). Bioinformatics analysis showed an association between SNPs and corresponding gene expression (p < 0.05), and PRKAA1 may affect GC by mediating RhoA.

Conclusion

This study suggests that PTGER4 and PRKAA1 SNPs might affect the susceptibility of GC, providing a new biological perspective for GC risk assessment, pathogenesis exploration, and personalized treatment.

Published: September 2023

Background

Cerebral ischaemia‒reperfusion (I/R) frequently causes late-onset neuronal damage. Breviscapine promotes autophagy in microvascular endothelial cells in I/R and can inhibit oxidative damage and apoptosis. However, the mediation mechanism of breviscapine on neuronal cell death is unclear.

Methods

First, transcriptome sequencing was performed on three groups of mice: the neuronal normal group (Control group), the oxygen-glucose deprivation/ reoxygenation group (OGD/R group) and the breviscapine administration group (Therapy group). Differentially expressed genes (DEGs) between the OGD/R and control groups and between the Therapy and OGD/R groups were obtained by the limma package. N6-methyladenosine (m6A) methylation-related DEGs were selected by Pearson correlation analysis. Then, prediction and confirmation of drug targets were performed by Swiss Target Prediction and UniProt Knowledgebase (UniProtKB) database, and key genes were obtained by Pearson correlation analysis between m6A-related DEGs and drug target genes. Next, gene set enrichment analysis (GSEA) and Ingenuity pathway analysis (IPA) were used to obtain the pathways of key genes. Finally, a circRNA-miRNA‒mRNA network was constructed based on the mRNAs, circRNAs and miRNAs.

Results

A total of 2250 DEGs between the OGD/R and control groups and 757 DEGs between the Therapy and OGD/R groups were selected by differential analysis. A total of 7 m6A-related DEGs, including Arl4d, Gm10653, Gm1113, Kcns3, Olfml2a, Stk26 and Tfcp2l1, were obtained by Pearson correlation analysis. Four key genes (Tfcp2l1, Kcns3, Olfml2a and Arl4d) were acquired, and GSEA showed that these key genes significantly participated in DNA repair, e2f targets and the g2m checkpoint. IPA revealed that Tfcp2l1 played a significant role in human embryonic stem cell pluripotency. The circRNA-miRNA‒mRNA network showed that mmu_circ_0001258 regulated Tfcp2l1 by mmu-miR-301b-3p.

Conclusions

In conclusion, four key genes, Tfcp2l1, Kcns3, Olfml2a and Arl4d, significantly associated with the treatment of OGD/R by breviscapine were identified, which provides a theoretical basis for clinical trials.

Published: September 2023

Background

Polypyrimidine tract binding protein 1 (PTBP1) has been found to play an important role in the occurrence and development of various tumors. At present, the role of PTBP1 in gastric cancer (GC) is still unknown and worthy of further investigation.

Methods

We used bioinformatics to analyze the expression of PTBP1 in patients with GC. Cell proliferation related experiments were used to detect cell proliferation after PTBP1 knockdown. Skeleton staining, scanning electron microscopy and transmission electron microscopy were used to observe the changes of actin skeleton. Proliferation and actin skeleton remodeling signaling pathways were detected by Western Blots. The relationship between PTBP1 and proliferation of gastric cancer cells was further detected by subcutaneous tumor transplantation. Finally, tissue microarray data from clinical samples were used to further explore the expression of PTBP1 in patients with gastric cancer and its correlation with prognosis.

Results

Through bioinformatics studies, we found that PTBP1 was highly expressed in GC patients and correlated with poor prognosis. Cell proliferation and cycle analysis showed that PTBP1 down-regulation could significantly inhibit cell proliferation. The results of cell proliferation detection related experiments showed that PTBP1 down-regulation could inhibit the division and proliferation of GC cells. Furthermore, changes in the morphology of the actin skeleton of cells showed that PTBP1 down-regulation inhibited actin skeletal remodeling in GC cells. Western Blots showed that PTBP1 could regulate proliferation and actin skeleton remodeling signaling pathways. In addition, we constructed PTBP1 Cas9-KO mouse model and performed xenograft assays to further confirm that down-regulation of PTBP1 could inhibit the proliferation of GC cells. Finally, tissue microarray was used to further verify the close correlation between PTBP1 and poor prognosis in patients with GC.

Conclusions

Our study demonstrates for the first time that PTBP1 may affect the proliferation of GC cells by regulating actin skeleton remodeling. In addition, PTBP1 is closely related to actin skeleton remodeling and proliferation signaling pathways. We suppose that PTBP1 might be a potential target for the treatment of GC.

Background

Socioeconomic status has long been associated with population health and health outcomes. While ameliorating social determinants of health may improve health, identifying and targeting areas where feasible interventions are most needed would help improve health equity. We sought to identify inequities in health and social determinants of health (SDOH) associated with local economic distress at the county-level.

Methods

For 3,131 counties in the 50 US states and Washington, DC (wherein approximately 325,711,203 people lived in 2019), we conducted a retrospective analysis of county-level data collected from County Health Rankings in two periods (centering around 2015 and 2019). We used ANOVA to compare thirty-three measures across five health and SDOH domains (Health Outcomes, Clinical Care, Health Behaviors, Physical Environment, and Social and Economic Factors) that were available in both periods, changes in measures between periods, and ratios of measures for the least to most prosperous counties across county-level prosperity quintiles, based on the Economic Innovation Group’s 2015–2019 Distressed Community Index Scores.

Results

With seven exceptions, in both periods, we found a worsening of values with each progression from more to less prosperous counties, with least prosperous counties having the worst values (ANOVA p < 0.001 for all measures). Between 2015 and 2019, all except six measures progressively worsened when comparing higher to lower prosperity quintiles, and gaps between the least and most prosperous counties generally widened.

Conclusions

In the late 2010s, the least prosperous US counties overwhelmingly had worse values in measures of Health Outcomes, Clinical Care, Health Behaviors, the Physical Environment, and Social and Economic Factors than more prosperous counties. Between 2015 and 2019, for most measures, inequities between the least and most prosperous counties widened. Our findings suggest that local economic prosperity may serve as a proxy for health and SDOH status of the community. Policymakers and leaders in public and private sectors might use long-term, targeted economic stimuli in low prosperity counties to generate local, community health benefits for vulnerable populations. Doing so could sustainably improve health; not doing so will continue to generate poor health outcomes and ever-widening economic disparities.

Published: September 2023

Background

Primary Systemic Sclerosis (PSS) is a connective tissue disorder characterized by excessive collagen deposition in the skin and internal organs. Interstitial lung disease (ILD) is a late demonstration of PSS and cytokines can contribute to the disease pathology. The purpose of the current study was to determine the association between serum interleukin-6 level and pulmonary involvement in progressive systemic sclerosis.

Methods and materials

Demographic data and serum interleukin-6 levels were measured for 30 PSS patients with pulmonary involvement (case group) and 30 PSS patients without pulmonary involvement (control group) following informed consent. The disease duration and activity, C-reactive protein (CRP), chest x-ray and highresolution CT scan (HRCT) findings, ejection fraction (EF) and echocardiography findings, and pulmonary artery pressure (PAP) were also determined in both groups.

Results

The age of patients in case and control groups was 52.5 ± 9.3 and 43.9 ± 9.7 years, respectively (p = 0.001). No significant difference was found between serum levels of IL-6 in case and control groups (73.1 ± 95.4 vs 46.7 ± 83.6 pg/ml, p = 0.267). However, IL-6 level was significantly higher in male case patients compared to male controls (p = 0.007). The duration of PSS was 11.6 ± 6.4 and 7.4 ± 4.2 years in case and control groups, respectively (p = 0.002). The quantitative CRP and PAP was also significantly higher in case patients (p = 0.01 and p < 0.001, respectively). There was found reticulonodular pattern in 20 (66.7%) of the cases, whereas 28 (93.3%) of the controls had normal Chest X-rays (CXR) (p < 0.001). EF was significantly lower in case patients compared to control patients (p = 0.001).

Conclusion

The serum level of IL-6 did not appear to have a relationship with pulmonary involvement, hence it could not be regarded as a potential therapeutic target.
