Abstract
Background
Aging is frequently associated with impairments of the musculoskeletal system and many elderly people experience joint discomfort or pain which might reduce their ability to move and consequently alter their quality of life. A beneficial effect of fish cartilage hydrolysate (FCH) on pain and joint function has recently been shown in an ACLT/pMMx osteoarthritis rat model.

Methods
We therefore performed an exploratory, non-comparative, multi-centric clinical trial including 33 subjects with moderate knee joint discomfort and loss of functionality to investigate the efficacy of FCH on their algo-functional status. We further determined the potential health benefit of FCH in an original clinical ex vivo study investigating the role of FCH human metabolites on primary human chondrocytes.

Results
FCH significantly improved knee pain and function, as assessed by the Knee injury and Osteoarthritis Outcome Score (KOOS). Moreover, FCH significantly reduced pain at rest and while walking, and patient global assessment (PGA), as assessed by the Visual Analogue Scale (VAS), and improved patients’ quality of life (SF-36). FCH metabolites decreased the synthesis of catabolic factors (MMP-13) and pro-inflammatory mediators (NO, PGE2) and limited the inhibitory effect of IL-1β on the synthesis of cartilage matrix components (GAG and collagen).

Conclusions
Thus, these data provide insights on the mode of action of FCH in humans and contribute to explain how FCH may relieve pain and improve joint function in subjects with knee discomfort. Although these preliminary data need to be confirmed in a randomized controlled trial, they strongly support the potential health benefit of such an active ingredient. Trial registration: The study was registered on clinicaltrials.gov with the identifier NCT04420091 (09/06/2020).

Abstract
Background
Non-operative management has been suggested as a therapy for uncomplicated appendicitis. Notwithstanding, the risk of missing an appendiceal tumor must be considered, being the surgical piece crucial to rule out neoplasms. Therefore, we aim to determine the incidence of appendiceal neoplasms in patients with acute appendicitis, tumor types and the importance of the anatomopathological study of the surgical piece.

Study design
Retrospective study in which we described patients who underwent emergent appendectomy with histopathological findings of appendiceal neoplasms from January 2012 to September 2018. Descriptive analysis included demographic variables, diagnostic methods, and surgical techniques.

Results
2993 patients diagnosed with acute appendicitis who underwent an emergency appendectomy. 64 neoplasms of the appendix were found with an incidence of 2,14%. 67.2% were women, the mean age was 46,4 years (± 19.5). The most frequent appendiceal neoplasms were neuroendocrine tumors (42,2%), followed by appendiceal mucinous neoplasms (35,9%), sessile serrated adenomas (18,8%), and adenocarcinomas (3,1%). In 89,1% of the cases, acute appendicitis was determined by imaging, and 14% of cases were suspected intraoperatively. Appendectomy was performed in 78,1% without additional procedures.

Conclusions
Appendiceal tumors are rare and must be ruled out in patients with suspected acute appendicitis. The incidence of incidental neoplasms is higher in this study than in the previously reported series. This information must be included in decision-making when considering treatment options for acute appendicitis.

Abstract
Background
There is a tendency of prompted global health systems to reduce the length of hospital stay without compromising patient safety or satisfaction. We evaluated the safety and viability of early discharge in patients undergoing minimally invasive radical prostatectomy (MIRP), as well as patient satisfaction with this strategy.

Methods
This longitudinal prospective study included 72 patients who underwent MIRP for prostate cancer. Three groups were performed according to the day of hospital discharge following surgery: same day (G1), first day after (G2), and second day after (G3). Satisfaction, adverse events, and readmission were analyzed for each group. Associations between clinicopathologic variables and same-day discharge were analyzed by comparing data between G1 patients who did and did not achieve same-day discharge.

Results
16.7% of patients were not discharged according to randomization (10 randomized to G1). 80% of G1 patients who did not achieve same-day discharge had Gleason scores of 3 + 4 or 4 + 3, which were observed in 35.7% of patients discharged on the same day (P < 0.05). Average prostate weight was significantly lower in patients who achieved same-day discharge than in those who did not (P < 0.01). Univariable logistic regression points to Gleason scores of 3 + 4 or 4 + 3 as the main factors associated with unsuccessful same-day discharge (P < 0.05). There were no significant differences in satisfaction scores.

Conclusions
Same-day discharge was both safe and feasible and does not appear to affect satisfaction in a subset of patients with prostate cancer. Surgeons should consider the Gleason score when determining whether same-day discharge is appropriate.

Abstract
Background
MicroRNA-19b (miR-19b) has been reported to be downregulated in polycystic ovary syndrome (PCOS), while its upstream regulators are unclear. We speculated that miR-19b could potentially form a binding relationship with BBOX1 antisense RNA 1 (BBOX1-AS1), a long non-coding RNA recognized for its critical role in ovarian cancer. Subsequently, we investigated into their interaction in PCOS.

Methods
The expression of miR-19b and BBOX1-AS1 in follicular fluid from both control women (n = 80) and women with PCOS (n = 80) was detected by RT-qPCR. Correlations were analyzed with Pearson’ correlation coefficient. The binding of miR-19b to the wild-type (-wt) ad mutant (-mut) BBOX1-AS1 was determined by RNA-RNA pulldown assay. Their interactions were detected by overexpression assay. Bromodeoxyuridine (BrdU) assay was applied for proliferation analysis.

Results
BBOX1-AS1 was highly upregulated, while miR-19b was downregulated in PCOS. There was no close correlation across PCOS and the control samples. Consistently, they did not regulate the expression of each other in granulosa cells. However, BBOX1-AS1-wt, but not BBOX1-AS1-mut, could directly interact with miR-19b. BBOX1-AS1 suppressed the role of miR-19b in inhibiting granulosa cell proliferation.

Conclusion
BBOX1-AS1 is highly upregulated in PCOS, and it may serve as an endogenous competing RNA for miR-19b to suppress its role in inhibiting granulosa cell proliferation. Our study suggested the role of BBOX1-AS1 as a potential target to treat PCOS.

AbstractBackgroundPuerperal sepsis is among the leading causes of preventable maternal death not only in developing countries but also in developed countries which is usually reported as the third or fourth common direct cause of maternal death. Although the prevalence of puerperal sepsis is low, it is the significant cause of maternal mortality, morbidities and other long-term complications like secondary infertility. The aim of this study was to assess the determinants of puerperal sepsis among post-partum mothers at Mekelle city public hospitals.MethodInstitution based unmatched case control study was conducted among 444 total sample size (111 cases and 333 controls) in Mekelle city public hospitals from March 21, 2021 to April 20, 2021. Consecutive sampling for the cases and systematic sampling for the controls was used. Pretested structured questionnaire was used to collect data and the data was entered into Epi data version 4.1 then cleaned, coded and edited and exported to SPSS version 23 statistical software for analysis. Logistic regression was done and variables with aP-value of < 0.25 on Binary logistic regression were taken to multiple logistic regression analysis. At 95% confidence interval, aP-value of < 0.05 was used as cut-off point to declare the association with the dependent variable.ResultsMultiple logistic regression analysis revealed that rural residence (AOR: 3, 95% CI: 1.50–5.90), no ANC follow up (AOR: 2.7, 95% CI: 1.08–6.71), duration of rupture of membrane > 24 h (AOR: 4.1, 95% CI: 1.60–10.58), duration of labor > 24 h (AOR: 4.3, 95% CI: 1.86–9.92), number of vaginal examination >  = 5 (AOR: 2.8, 95% CI: 1.26–6.26), cesarean section mode of delivery (AOR: 2.8, 95% CI: 1.48–5.20) and no PNC follow up (AOR: 3.9, 95% CI: 1.60–9.36) were the determinant factors of puerperal sepsis in this study.ConclusionThe determinants of puerperal sepsis in this study were rural residence, not having antenatal care, prolonged duration of rupture of membrane, prolonged duration of labor, frequent number of vaginal examination, cesarean section and not having postnatal care. It is recommended that strengthening provision of health education on danger signs of pregnancy, parthograph utilization and avoiding of frequent vaginal examinations.

Published: September 2023

Abstract
Background
Mental-health-related stigma among physicians towards people with mental illnesses remains a barrier to quality care, yet few curricula provide training with a proactive focus to reduce the potential negative impacts of stigma. The aim of our study was to explore medical students’ perspectives on what areas of learning should be targeted (where stigma presents) and how they could be supported to prevent the formation of negative attitudes.

Methods
Six focus group discussions were conducted with second, third, and fourth-year postgraduate medical students (n = 34) enrolled at The University of Melbourne Medical School in September – October 2021. Transcripts were analysed using inductive thematic analysis.

Results
In terms of where stigma presents, three main themes emerged – (1) through unpreparedness in dealing with patients with mental health conditions, (2) noticing mentors expressing stigma and (3) through the culture of medicine. The primary theme related to 'how best to support students to prevent negative attitudes from forming' was building stigma resistance to reduce the likelihood of perpetuating stigma towards patients with mental health conditions and therefore enhance patient care. The participants suggest six primary techniques to build stigma resistance, including (1) reflection, (2) skills building, (3) patient experiences, (4) examples and exemplars, (5) clinical application and (6) transforming structural barriers. We suggest these techniques combine to form the ReSPECT model for stigma resistance in the curriculum.

Conclusions
The ReSPECT model derived from our research could provide a blueprint for medical educators to integrate stigma resistance throughout the curriculum from year one to better equip medical students with the potential to reduce interpersonal stigma and perhaps self-stigma. Ultimately, building stigma resistance could enhance care towards patients with mental health conditions and hopefully improve patient outcomes.
Patient priorities for fulfilling the principle of respect in research: findings from a modified Delphi study
Authors: Kraft Stephanie A. , Duenas Devan M. , Shah Seema K. 
Published: September 2023

Abstract
Background
Standard interpretations of the ethical principle of respect for persons have not incorporated the views and values of patients, especially patients from groups underrepresented in research. This limits the ability of research ethics scholarship, guidance, and oversight to support inclusive, patient-centered research. This study aimed to identify the practical approaches that patients in community-based settings value most for conveying respect in genomics research.

Methods
We conducted a 3-round, web-based survey using the modified Delphi technique to identify areas of agreement among English-speaking patients at primary care clinics in Washington State and Idaho who had a personal or family history of cancer. In Round 1, respondents rated the importance of 17 items, identified in prior qualitative work, for feeling respected. In Round 2, respondents re-rated each item after reviewing overall group ratings. In Round 3, respondents ranked a subset of the 8 most highly rated items. We calculated each item’s mean and median rankings in Round 3 to identify which approaches were most important for feeling respected in research.

Results
Forty-one patients consented to the survey, 21 (51%) completed Round 1, and 18 (86% of Round 1) completed each of Rounds 2 and 3. Two sets of rankings were excluded from analysis as speed of response suggested they had not completed the Round 3 ranking task. Respondents prioritized provision of study information to support decision-making (mean ranking 2.6 out of 8; median ranking 1.5) and interactions with research staff characterized by kindness, patience, and a lack of judgment (mean ranking 2.8; median ranking 2) as the most important approaches for conveying respect.

Conclusions
Informed consent and interpersonal interactions are key ways that research participants experience respect. These can be supported by other approaches to respecting participants, especially when consent and/or direct interactions are infeasible. Future work should continue to engage with patients in community-based settings to identify best practices for research without consent and examine unique perspectives across clinical and demographic groups in different types of research.
SelANet: decision-assisting selective sleep apnea detection based on confidence score
Authors: Bark Beomjun , Nam Borum , Kim In Young 
Published: September 2023

Abstract
Background
One of the most common sleep disorders is sleep apnea syndrome. To diagnose sleep apnea syndrome, polysomnography is typically used, but it has limitations in terms of labor, cost, and time. Therefore, studies have been conducted to develop automated detection algorithms using limited biological signals that can be more easily diagnosed. However, the lack of information from limited signals can result in uncertainty from artificial intelligence judgments. Therefore, we performed selective prediction by using estimated respiratory signals from electrocardiogram and oxygen saturation signals based on confidence scores to classify only those sleep apnea occurrence samples with high confidence. In addition, for samples with high uncertainty, this algorithm rejected them, providing a second opinion to the clinician.

Method
Our developed model utilized polysomnography data from 994 subjects obtained from Massachusetts General Hospital. We performed feature extraction from the latent vector using the autoencoder. Then, one dimensional convolutional neural network—long short-term memory (1D CNN-LSTM) was designed and trained to measure confidence scores for input, with an additional selection function. We set a confidence score threshold called the target coverage and performed optimization only on samples with confidence scores higher than the target coverage. As a result, we demonstrated that the empirical coverage trained in the model converged to the target coverage.

Result
To confirm whether the model has been optimized according to the objectives, the coverage violation was used to measure the difference between the target coverage and the empirical coverage. As a result, the value of coverage violation was found to be an average of 0.067. Based on the model, we evaluated the classification performance of sleep apnea and confirmed that it achieved 90.26% accuracy, 91.29% sensitivity, and 89.21% specificity. This represents an improvement of approximately 7.03% in all metrics compared to the performance achieved without using a selective prediction.

Conclusion
This algorithm based on selective prediction utilizes confidence measurement method to minimize the problem caused by limited biological information. Based on this approach, this algorithm is applicable to wearable devices despite low signal quality and can be used as a simple detection method that determine the need for polysomnography or complement it.

Published: September 2023

Abstract
Background
Some patients infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) go on to experience post-COVID-19 condition or long COVID. Preliminary findings have given rise to the theory that long COVID may be due in part to a deranged immune response. In this study, we assess whether there is an association between SARS-CoV-2 infection and the incidence of immune-mediated inflammatory diseases (IMIDs).

Methods
Matched cohort study using primary care electronic health record data from the Clinical Practice Research Datalink Aurum database. The exposed cohort included 458,147 adults aged 18 years and older with a confirmed SARS-CoV-2 infection and no prior diagnosis of IMIDs. They were matched on age, sex, and general practice to 1,818,929 adults with no diagnosis of confirmed or suspected SARS-CoV-2 infection. The primary outcome was a composite of any of the following IMIDs: autoimmune thyroiditis, coeliac disease, inflammatory bowel disease (IBD), myasthenia gravis, pernicious anaemia, psoriasis, rheumatoid arthritis (RA), Sjogren’s syndrome, systemic lupus erythematosus (SLE), type 1 diabetes mellitus (T1DM), and vitiligo. The secondary outcomes were each of these conditions separately. Cox proportional hazard models were used to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI) for the primary and secondary outcomes, adjusting for age, sex, ethnic group, smoking status, body mass index, relevant infections, and medications.

Results
Six hundred and nighty six (0.15%) and 2230 (0.12%) patients in the exposed and unexposed cohort developed an IMID during the follow-up period over 0.29 person-years, giving a crude incidence rate of 4.59 and 3.65 per 1000 person-years, respectively. Patients in the exposed cohort had a 22% increased risk of developing an IMID, compared to the unexposed cohort (aHR 1.22, 95% CI 1.12 to 1.33). The incidence of three IMIDs was significantly associated with SARS-CoV-2 infection. These were T1DM (aHR 1.56, 1.09 to 2.23), IBD (aHR 1.36, 1.18 to 1.56), and psoriasis (1.23, 1.05 to 1.42).

Conclusions
SARS-CoV-2 was associated with an increased incidence of IMIDs including T1DM, IBD and psoriasis. However, these findings could be potentially due to ascertainment bias. Further research is needed to replicate these findings in other populations and to measure autoantibody profiles in cohorts of individuals with COVID-19.
Proposed protocol for utilising high-flow nasal oxygen therapy in treatment of dogs hospitalised due to pneumonia
Authors: Teppo Anna-Maija , Rossi Heini , Rajamäki Minna M. , Hyytiäinen Heli K. 
Published: September 2023

Abstract
Background
High-flow nasal oxygen (HFNO) therapy is a non-invasive respiratory support method that provides oxygen-enriched, warmed, and humidified air to respiratory-compromised patients. It is widely used in human medical care, but in veterinary medicine it is still a relatively new method. No practical guidelines exist for its use in canine pneumonia patients, although they could potentially benefit from HFNO therapy. This study aims to provide a new, safe, non-invasive, and effective treatment protocol for oxygen supplementation of non-sedated dogs with pneumonia.

Methods
Twenty privately owned dogs with pneumonia will receive HFNO therapy at a flow rate of 1–2 L/kg, and the fraction of inspired oxygen will be determined individually (ranging from 21% to 100%). HFNO therapy will continue as long as oxygen support is needed based on clinical evaluation. Patients will be assessed thrice daily during their hospitalisation, with measured primary outcomes including partial pressure of oxygen, oxygen saturation, respiratory rate and type, days in hospital, and survival to discharge.

Discussion
The proposed protocol aims to provide a practical guideline for applying HFNO to dogs hospitalised due to pneumonia. The protocol could enable more efficient and well-tolerated oxygenation than traditional methods, thus hastening recovery and improving survival of pneumonia patients.
