Implementation and Outcomes of Multidisciplinary Diabetes Management Program Among Type 2 Diabetic Patients: A Comparative Study.

BACKGROUND: Current guidelines recommend shifting physician-led care (PLC) for type 2 diabetes mellitus (T2DM) to more effective multidisciplinary health care (MHC). However, few researchers have studied its real-life implementation in Saudi Arabia. Therefore, we aimed to assess the implementation and compare the outcomes of an MDC diabetes management program (DMP) among T2DM patients to a PLC at a general hospital after one year of follow-up in a real-world practice setting. METHODS: We conducted this comparative patient files review study by analyzing medical records of all T2DM patients at two private care centers. Both were compared for their effectiveness in achieving two outcomes: the glycated hemoglobin (HbA1c) <7% and low-density lipoprotein-cholesterol (LDL-c) <70 mg/dl at the end of the first year. Additionally, we assessed the implementation of the DMP. RESULTS: Eight hundred thirty-four medical records were reviewed, 537 from DMP, and 279 from the PLC center. The personal health coordination was almost complete (97.8%) in the DMP, but the implementation was incomplete regarding nutrition (65.7%), dental exam (64.8%), and foot care (58.3%). Both care groups were matched for age (p = 0.056), gender (p = 0.085), duration of diabetes (p = 0.217), and basal glycemic control (p = 0.171). The DMP showed a significant net decrease in HbA1c (-0.5 [IQR 1.47%] vs -0.2 [IQR 3.05%], p = 0.0001) and LDL-c (-10 [IQR 50] vs -5 [IQR 60.5] mg/dl, p = 0.004) compared to PLC. A higher percentage of patients achieved glycemic control in the DMP than in the PLC (49.4% vs 38.7%, p = 0.038). However, both programs demonstrated similar outcomes in lipid control (28.7% vs. 30%, p = 0.695). CONCLUSION: Despite some gaps in implementation, one year of DMP showed better glycemic control among T2DM patients compared to PLC. Both programs were comparable in terms of lipid control. Further studies identifying the gaps in care implementation could improve sustainability, future replication, and generalizability of similar programs to other healthcare systems in Saudi Arabia.

Access to healthcare services and confidence in healthcare professionals' management of malaria: the views of Francophone sub-Saharan African Immigrants living in western Canada.

BACKGROUND: There is a paucity of knowledge about the healthcare attitudes and practices of French-speaking immigrants originating from Sub-Saharan Africa (FISSA) living in minority settings. The purpose of this study was to characterize FISSA healthcare experiences and confidence in the malaria-related knowledge of health professionals in Edmonton. METHODS: A structured survey was used to examine a cohort of 382 FISSA (48% female; 52% male) living in Edmonton. FISSA general healthcare attitudes, experiences and satisfaction with the Canadian healthcare system were studied. Healthcare Competency Perception (HCP) was characterized by using an index score. Statistical analyses were performed to evaluate the impact of healthcare experiences and other outcomes. RESULTS: Intriguingly, while only 42% of FISSA had a French-speaking family physician, 83% (197/238) of those who had received health care services in Alberta found that access to medical treatment was easy, and 77% (188/243) were satisfied with received care. Although 70% (171/243) of FISSA did not receive services in French, 82% (199/243) surprisingly reported having good levels of comprehension during their visits. Satisfaction with care was associated with having a family physician (p = 0.018) and having health insurance (p = 0.041). Nevertheless, confidence in the healthcare system's ability to treat malaria effectively was significantly lower, with only 39% (148/382) receiving a positive score on the HCP index. CONCLUSION: This study provides an important insight into FISSA experience with and perception of the Alberta's healthcare system.

Hearing Loss with Vision Impairment: Usher Syndrome. A Case of the East Democratic Republic of Congo.

Usher syndrome (USH) is a clinically heterogeneous condition characterized by sensorineural hearing loss, progressive retinal degeneration, and vestibular dysfunction. There are two phenotypically recognizable types of Usher syndrome described in the literature. Usher type 1 individual have no vestibular function and profound sensorineural hearing loss. Usher type 2 individuals have a normal vestibular function and mild-to-severe hearing loss with visual impairment that is presented later in life. We are reporting a case of 35 years old gentleman with hearing loss and visual impairment presented to the ENT clinic at the tertiary care center. Clinical evaluations as well as comprehensive testing of hearing, vestibular function, and visual function have confirmed USH. It's a rare but serious cause of hearing loss that requires comprehensive multidisciplinary evaluation in conjunction with an ophthalmology team. Further genetic, audiological, and vestibular assessments are required to help diagnose and management of specific subtypes of this syndrome.

Synthetic non-toxic anti-biofilm agents as a strategy in combating bacterial resistance.

The tremendous increase in the bacterial resistance to the available antibiotics is a serious problem for the treatment of various infections. Biofilm formation in bacteria significantly contributes to the bacterial survival in host cells, and is considered as an crucial factor, responsible for bacterial resistance. The response of the bacterial cells in the biofilm to antibiotics is completely different from that of the free floating planktonic cells of the same strain. The anti-biofilm agents that could inhibit the biofilm production without affecting the bacterial growth, apply less selective pressure over the bacterial strains than the traditional antibiotics; thus the development of bacterial resistance would be of low incidence. Many attempts have been performed to discover novel agents capable of interfering with the bacterial biofilm life cycle, and several compounds have shown promising activities in suppressing the biofilm production or in dispersing mature existing biofilms. This review describes the different chemical classes that have anti-biofilm effects against different Gram-positive and Gram-negative bacteria without affecting the bacterial growth.

Adjunctive effect of collagen membrane coverage to L-PRF in the treatment of periodontal intrabony defects: a randomized controlled clinical trial with biochemical assessment.

BACKGROUND: The innovation of leukocyte platelet-rich fibrin (L-PRF) has added enormous impact on wound healing dynamics especially the field of periodontal regeneration. The release of growth factors (GF) is thought to improve the clinical outcomes in infrabony defects. The aim of this study was to evaluate the clinical effect of covering L-PRF contained infrabony defects with collagen membranes (CM), and to compare their GF release profile to uncovered L-PRF defects and open flap debridement (OFD). METHODS: Thirty non- smoking patients with infrabony pockets participated to be randomly assigned to OFD group (n = 10), L-PRF group (n = 10), or L-PRF protected CM group (n = 10). Plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL) and the radiographic defect base fill (DBF) were measured at baseline and at 6 month following surgical intervention. Gingival crevicular fluid samples were obtained on days 1, 3, 5, 7, 14, 21 and 30 days following surgery for the Platelet Derived Growth Factor-BB (PDGF-BB) and Vascular Endothelial Growth Factors (VEGF) release profile evaluation. RESULTS: For all patients, a statistically significant (P ≤ 0.05) reduction in PI, GI, PD and CAL were reported throughout the study period. Differences between the three treatment modalities were not statistically significant. PRF + CM showed a statistically significant DBF compared to OFD and L-PRF groups at follow up. Quantitative analysis of PDGF-BB and VEGF levels demonstrated a statistically significant (P < 0.001) decline between measurement intervals for all groups with no statistically significant differences between the three groups. CONCLUSION: Within the limitations of this study, L-PRF coverage with CM may augment defect base fill through its mechanical protective effect without enhancement in the release profile of VEGF and PDGF. The non-significant intergroup differences question the validity of the claimed extra physiologic concentration of GF offered by L-PRF harvests. TRIAL REGISTRATION: The present study was registered at ClinicalTrials.gov (NCT05496608), (11/08/2022).

Gremlin-1 Level In Polycystic Ovary Syndrome And Its Clinical Correlations; A Case Control Study.

Objectives: To evaluate the involvement of the level of Gremlin-1 in serum and follicular fluid in the diagnosis of polycystic ovary syndrome. Method: The case-controlstudy was conducted at the Kafrelsheikh University Hospital, Egypt, from September 2021 to February 2022, and comprised women with polycystic ovary syndrome and healthy controls. All participants were subjected to a detailed clinical assessment, complete clinical examination and hormonal profile assessment. Gremlin1 concentrationsin plasma and follicular fluid samples were assessed by a double-antibody sandwich enzyme-linked immunosorbent assay kit. Data was analysed using SPSS 20. RESULTS: Of the 90 subjects, 45(50%) were patients with a mean age of 29.53±4.82 years, and 45(50%) were controls with a mean age of 30.89±6.08 (p>0.05). Mean weight, body massindex, waist circumference and waist-hip ratio were significantly higher in patients compared to controls (p<0.05). Serum and follicular fluid Gremlin-1 levels were significantly higher in the patient group (p<0.05). The best cutoff of serum Gremlin-1 in the diagnosis of polycystic ovary syndrome was ≥1.325ng/ml with area under curve 0.857,sensitivity 93.3%,specificity 68.9%, positive predictive value 75%, negative predictive value 91.2% and overall accuracy 81.1%. The best cutoff of follicular fluid Gremlin-1 in the diagnosis of polycystic ovary syndrome was ≥1.725ng/ml with area under curve 0.789,sensitivity 73.3%,specificity 68.9%, positive predictive value 70.2%, negative predictive value 72.1% and overall accuracy 71.1%. CONCLUSIONS: There was a strong correlation between serum and follicular Gremlin-1 levelsin polycystic ovary syndrome patients.

Assessment Of Endometrial Integrin Beta 5 In Women With Unexplained Recurrent Pregnancy Loss.

Objectives: To examine the relationship between endometrial integrin beta 5 level and risk of recurrent pregnancy loss. Method: The descriptive, prospective, observational, case-controlstudy was conducted at the Kafrelsheikh University Hospital, Egypt, from January to May 2022, and comprised women aged up to 35 years with at least 1 live birth delivery beyond 20-week gestation with normal thyroid and prolactin levels. Age-matched normal fertile women were enrolled as controls. All the participants were subjected to detailed history and complete clinical examination. Endometrial integrin beta 5 was assessed using an antibody sandwich enzyme-linked immunosorbent assay. Data was analysed using SPSS 20. RESULTS: Of the 50 subjects, 25(50%) were cases with a mean age of 26.72±2.64 years, and 25(50%) were controls with a mean age of 25.36±2.16 years. The integrin beta 5 level was significantly lower among the cases than the controls (p<0.05). The best cut-off level of serum integrin beta 5 was ≤2.5765 with area under curve 0.886, sensitivity 88%, specificity 76%, positive predictive value 78.6%, negative predictive value 86.4%, and accuracy 82%. CONCLUSIONS: Therewas an inverse correlationbetween endometrial integrinbeta 5 andthe risk ofrecurrentpregnancy loss.

EUS-guided cyanoacrylate injection into the perforating vein versus direct endoscopic injection in the treatment of gastric varices.

Background and study aims Endoscopic injection of gastric varices (GVs) using cyanoacrylate (CYA) is associated with significant adverse events (AEs). We aimed to compare the efficacy and safety of endoscopic ultrasound (EUS)-guided CYA injection into the perforating vein versus direct endoscopic injection (DEI) of CYA in treatment of high-risk GVs. Patients and methods This was a randomized controlled trial that included 52 patients with high-risk GVs. Group A underwent EUS-guided injection into the perforator vein and Group B underwent DEI of 1 mL CYA. Endoscopic examination and Doppler EUS were repeated after 3 months to confirm eradication. Obliteration by Doppler EUS was considered by absence of Doppler flow within the varix. Repeated injection was performed in the absence of obliteration. Doppler EUS examination was repeated at 3 and 6 months after each injection. Results Forty-three patients including 27 males and 16 females with mean age 57 years completed the study. Variceal obliteration was achieved during the index session after 3 months in eight of 21 (38.1 %) in group B compared to 17 of 22 (77.2 %) in group A ( P  = 0.014). There was a significant difference in the amount of CYA needed to achieve obliteration in group B compared to group A (2 vs.1 mL, P  = 0.027). There was no statistically significant difference in the overall AE rate between group A and group B (4.5 % vs. 14.3 %, P  = 0.345). Conclusions EUS-guided CYA injection into the perforating veins achieved less amount of CYA, fewer number of sessions to obliteration, and similar overall AE rates in the treatment of high-risk GVs compared to DEI.

Role of endoscopic ultrasound and cyst fluid tumor markers in diagnosis of pancreatic cystic lesions.

BACKGROUND: Pancreatic cystic lesions (PCLs) are common in clinical practice. The accurate classification and diagnosis of these lesions are crucial to avoid unnecessary treatment of benign lesions and missed opportunities for early treatment of potentially malignant lesions. AIM: To evaluate the role of cyst fluid analysis of different tumor markers such as cancer antigens [e.g., cancer antigen (CA)19-9, CA72-4], carcinoembryonic antigen (CEA), serine protease inhibitor Kazal-type 1 (SPINK1), interleukin 1 beta (IL1-ß), vascular endothelial growth factor A (VEGF-A), and prostaglandin E2 (PGE2)], amylase, and mucin stain in diagnosing pancreatic cysts and differentiating malignant from benign lesions. METHODS: This study included 76 patients diagnosed with PCLs using different imaging modalities. All patients underwent endoscopic ultrasound (EUS) and EUS-fine needle aspiration (EUS-FNA) for characterization and sampling of different PCLs. RESULTS: The mean age of studied patients was 47.4 ± 11.4 years, with a slight female predominance (59.2%). Mucin stain showed high statistical significance in predicting malignancy with a sensitivity of 87.1% and specificity of 95.56%. It also showed a positive predictive value and negative predictive value of 93.1% and 91.49%, respectively (P < 0.001). We found that positive mucin stain, cyst fluid glucose, SPINK1, amylase, and CEA levels had high statistical significance (P < 0.0001). In contrast, IL-1ß, CA 72-4, VEGF-A, VEGFR2, and PGE2 did not show any statistical significance. Univariate regression analysis for prediction of malignancy in PCLs showed a statistically significant positive correlation with mural nodules, lymph nodes, cyst diameter, mucin stain, and cyst fluid CEA. Meanwhile, logistic multivariable regression analysis proved that mural nodules, mucin stain, and SPINK1 were independent predictors of malignancy in cystic pancreatic lesions. CONCLUSION: EUS examination of cyst morphology with cytopathological analysis and cyst fluid analysis could improve the differentiation between malignant and benign pancreatic cysts. Also, CEA, glucose, and SPINK1 could be used as promising markers to predict malignant pancreatic cysts.

Gaps in knowledge and practices of malaria prevention in Francophone African immigrants in Metropolitan Edmonton.

BACKGROUND: Important knowledge gaps exist in the understanding of the management of the risks of imported malaria in Canada among Francophone immigrants from sub-Saharan Africa (FISSA). The aim of this cross-sectional study was to investigate the malaria related-knowledge, attitude and practices (KAP) of FISSA in Edmonton, where these immigrants are in an official minority language situation and the impact of language barriers on these factors. METHODS: A structured survey was used to examine the KAP of 382 FISSA in the Edmonton area from 2018 to 2019. Fisher's Exact Test was applied to determine if there were associations between knowledge of malaria and different risk factors. RESULTS: Almost all FISSA (97%) had an accurate knowledge of fever as the key symptom of malaria. Interestingly, 60% of participants identified bed nets as a preventive method and only 19% of participants had accurate knowledge of malaria transmission. An accurate knowledge of symptoms was significantly associated with a high perceived risk of contracting malaria [odds ratio (OR) 4.33, 95% confidence interval (CI) 1.07-20.62]. Furthermore, even though 70% of FISSA had a high perceived risk of contracting malaria in endemic regions, only 52% of travellers had a pre-travel medical encounter. Importantly, language was not the predominant reason for not seeking pre-travel medical advice, although 84% of respondents chose French as their official language of preference when seeking medical advice. Having a French-speaking physician was correlated with satisfactory prevention knowledge (OR 1.96, 95% CI 1.16-3.35). With respect to health-seeking behaviour, 88% of respondents with a child < 5 years of age would seek medical care for fever in the child after travel to sub-Saharan Africa (SSA). CONCLUSION: This study highlights that factors other than knowledge, risk assessment, and language might determine the lack of compliance with pre-travel medical encounters. It underscores the need for effective strategies to improve this adherence in minority settings.

Endoscopic resection of superficial bowel neoplasia: The unmet needs in the Egyptian practice.

BACKGROUND: Management of superficial bowel neoplasia (SBN) in early stages is associated with better outcomes. The last few decades experienced a paradigm shift in the management of SBN with the introduction of advanced endoscopic resection techniques (ERTs). However, there are no clear data about the aspects of ERTs in Egypt despite the growing gastroenterology practice. AIM: To investigate the knowledge, attitude, and practice of ERTs toward management of SBN among Egyptian practitioners and the suitability of the endoscopy units' infrastructures toward these techniques. METHODS: An online 2-pages questionnaire was used. The first page comprised demographic data, and questions for all physicians, about the knowledge (11 questions) of and attitude (5 questions) toward ERTs as a therapeutic option for SBN. The second page investigated the practice of ERTs by endoscopists (6 questions) and the infrastructures of their endoscopy units (14 questions). The survey was disseminated through July 2021 and the data were collected in an excel sheet and later analyzed anonymously. RESULTS: The complete responses were 833/2300 (36.2%). The majority of the participants were males (n = 560, 67.2%), middle-aged (n = 366, 43.9%), consultants (n = 464, 55.7%), gastroenterologists (n = 678, 81.4%), spending ≥ 15 years in practice (n = 368, 44.2%), and were working in university hospitals (n = 569, 68.3%). The majority correctly identified the definition of SBN (88.4%) and the terms polypectomy, endoscopic mucosal resection (EMR), and endoscopic submucosal dissection (ESD) (92.1%, 90.2%, and 89.1% respectively). However, 26.9%, 43.2% and 49.5% did not recognize the clear indication of polypectomy, EMR, and ESD respectively. Although 68.1% of physicians are convinced about the ERTs for management of SBN; only 8.9% referred all candidate cases for ERTs. About 76.5% of endoscopists had formal training in the basic polypectomy techniques while formal training for EMR and ESD was encountered only in 31.9% and 7.2% respectively. About 71.6% and 88.4% of endoscopists did not perform EMR or ESD in the last one year. Consequently, the complication rate reported by endoscopists was limited to 18.1% (n = 103) of endoscopists. Only 25.8% of endoscopists feel confident in the management of ERTs-related complications and a half (49.9%) were not sure about their competency. Regarding the endoscopy units' infrastructures, only 4.2% of the centers had their endoscopes 100% armed with optical enhancements and 54.4% considered their institutions ready for managing ERTs-related complications. Only 18.3% (n = 104) of endoscopists treated their complicated cases surgically because the most frequent ERTs-related complications were procedural bleeding (26.7%), and perforations (17%). CONCLUSION: A significant deficiency was reported in the knowledge and attitude of Egyptian practitioners caring for patients with SBN toward ERTs. The lack of trained endoscopists in both EMR and ESD in part is due to unsuitable infrastructures of many endoscopy units.

Extracellular vesicles in low volume uterine lavage and serum: novel and promising biomarker for endometritis in Arabian mares.

BACKGROUND: Extracellular vesicles (EVs) are a promising biomarker and play a vital role in cell-cell communication. This study aimed (I) to identify and characterize EVs from low volume uterine lavage (LVL) and serum in mares with endometritis, compared to healthy controls and (II) to measure serum levels of interleukin 6 (IL-6), and prostaglandins (PGF2α and PGE2). Mares were divided into 30 sub-fertile (endometritis) and 20 fertile (controls). Serum and LVL was collected for EV isolation, and determination of serum levels of inflammatory mediators. Characterization and visualization of EVs were done by electron microscopy, dynamic light scattering and flow cytometry. RESULTS: Serial ultracentrifugation of LVL and use of a commercial kit for serum were strategies for EVs isolation. Mares with endometritis released higher amounts of larger size EVs. The EVs from mares with endometritis differentially expressed CD9 and CD63, compared to controls. Mares suffering from endometritis evoked higher levels of inflammatory mediators. CONCLUSIONS: Thus, EVs could be used for a better understanding the regulatory mechanisms associated with developing endometritis in mares.

Methylprednisolone, dexamethasone or hydrocortisone for acute severe pediatric asthma: does it matter?

OBJECTIVE: Various intravenous (IV) corticosteroids are available for acute severe asthma (ASA) treatment. The choice of IV corticosteroids varies broadly and depends on institution, country, or physician preferences. In this study, we compared the efficacy of IV methylprednisolone, hydrocortisone and dexamethasone in ASA treatment during pediatric intensive care unit (PICU) admission. METHODS: The study was a prospective randomized clinical trial. We enrolled patients of 1-21 years after they were admitted to the PICU requiring continuous beta-2 agonist treatment. Patients were randomized into three groups: Group A: IV Methylprednisolone, Group B: IV Hydrocortisone and Group C: IV Dexamethasone. The primary outcomes measured were durations of beta-2 agonist continuous nebulization treatment. Secondary outcomes, included PICU and hospital length of stay (LOS), pediatric asthma severity score (PASS), need for mechanical ventilation and maximum dose of beta-2 agonist treatment. RESULTS: 61 patients were included in the analysis. 22 patients recruited in Group A, 20 in group B and 19 group C. Median durations of beta-2-agonist treatment were 23 h (QR 16-38) for methylprednisolone, 27 h (QR 16-40) for hydrocortisone, and 32 h (QR 16-48) for dexamethasone (p = 0.90). There was no difference in PICU LOS, hospital LOS, PASS score, B2 agonist maximum dose, or need for ventilation support. CONCLUSIONS: The use of IV methylprednisolone, hydrocortisone, and dexamethasone have equivalent efficacy when used at the appropriate doses. Studies with larger cohorts are needed to compare the effectiveness of IV corticosteroids in the management of ASA in the PICU setting.

Development and Validation of an Objective Scoring Tool for Robot-Assisted Partial Nephrectomy: Scoring for Partial Nephrectomy.

Objective: To develop a structured and objective scoring tool for assessment of robot-assisted partial nephrectomy (RAPN): Scoring for Partial Nephrectomy (SPaN). Materials and Methods:Content development: RAPN was deconstructed into 6 domains by a multi-institutional panel of 10 expert robotic surgeons. Performance on each domain was represented on a Likert scale of 1 to 5, with specific descriptions of anchors 1, 3, and 5. Content validation: The Delphi methodology was utilized to achieve consensus about the description of each anchor for each domain in terms of appropriateness of the skill assessed, objectiveness, clarity, and unambiguous wording. The content validity index (CVI) of ≥0.75 was set as cutoff for consensus. Reliability: 15 de-identified videos of RAPN were utilized to determine the inter-rater reliability using linearly weighted percent agreement, and Construct validation of SPaN was described in terms of median scores and odds ratios. Results: The expert panel reached consensus (CVI ≥0.75) after 2 rounds. Consensus was achieved for 36 (67%) statements in the first round and 18 (33%) after the second round. The final six-domain SPaN included Exposure of the kidney; Identification and dissection of the ureter and gonadal vessels; Dissection of the hilum; Tumor localization and exposure; Clamping and tumor resection; and Renorrhaphy. The linearly weighted percent agreement was >0.75 for all domains. There was no difference between median scores for any domain between attendings and trainees. Conclusion: Despite the lack of significant construct validity, SPaN is a structured, reliable, and procedure-specific tool that can objectively assesses technical proficiency for RAPN.

Bathroom activities monitoring for older adults by a wrist-mounted accelerometer using a hybrid deep learning model.

Monitoring activities of daily life (ADLs) allows to evaluate health conditions for older adults. However, there are still a limited number of studies on bathroom activities monitoring using a wrist-mounted accelerometer. To fill this gap, in this study, researchers collected data from 15 older adults wearing a wrist-mounted accelerometer. Six bathroom activities, i.e., dressing, undressing, brushing teeth, using toilet, washing face, and washing hands, were investigated. In total, 49.4-hour data for bathroom activities were collected. A hybrid convolutional neural network (CNN) is introduced for bathroom activity recognition. This hybrid CNN model is developed using both hand-crafted and CNN-based features as input. The proposed hybrid CNN model is compared to four machine learning models, i.e., Multilayer Perceptron (MLP), Support Vector Machines (SVM), K-nearest Neighbors (KNN), and Decision Trees (DT), and a conventional CNN model. Based on the classification results of leave-one-subject-out cross-validation (LOSO), the hybrid CNN model outperformed the other models. The hybrid CNN model is also tested based on a transfer learning method. As a calibration step based on LOSO, the transfer learning method additionally trains the model with an example of each activity from the test subject. The transfer learning method obtained better classification performance than LOSO. With transfer learning, the f1-score for using toilet was improved from 0.7784 to 0.8437. This study proposes a deep learning model fusing hand-crafted features and CNN-based features. Besides, the transfer learning method offers a way to build subject-dependent models to improve the classification performance.Clinical relevance -This provides a model that helps monitoring older adults' bathroom activities using a single wrist-mounted accelerometer.

Alterations in the Expression Profile of Serum miR-155, miR-223, miR-17, miR-200a, miR-205, as well as Levels of Interleukin 6, and Prostaglandins during Endometritis in Arabian Mares.

So far the intimate link between serum microRNA (miRNA) and uterine inflammation in mares is unknown. We aimed (I) to investigate expression profile of eca-miR-155, eca-miR-223, eca-miR-17, eca-miR-200a, and eca-miR-205 (II) and to measure concentrations of interleukin 6 (IL-6), and prostaglandins (PGF2α and PGE2) in serum of mares with healthy and abnormal uterine status (endometritis). This study was conducted on 80 Arabian mares: young (4-7 years), and old (8-14 years). Mares were divided into 48 sub-fertile (endometritis) and 32 fertile (control) at stud farms. Serum was collected for measuring IL-6, PGF2α, and PGE2, as well as miRNA isolation and qRT-PCR. Concentrations of IL-6, PGE2, and PGF2α were higher in mares with endometritis compared to control. Age of mares had a remarkable effect on IL-6, PGE2, and PGF2α concentrations. Relative abundance of eca-miR-155, eca-miR-223, eca-miR-17, eca-miR-200a, and eca-miR-205 was higher in both young and old mares with endometritis. We noticed that eca-miR-155, eca-miR-223, eca-miR-200a, and eca-miR-205 revealed higher expression level in old than young mares with endometritis. This is the first study that has revealed the changes in cell free miRNA and serum inflammatory mediators during endometritis, and these findings could be used for a better understanding the pathophysiology mechanisms of endometritis in equine.

Repurposing a PICU for Adult Care in a State Mandated COVID-19 Only Hospital: Outcome Comparison to the MICU Cohort to Determine Safety and Effectiveness.

Objective: The ongoing coronavirus 2019 (COVID-19) pandemic is disproportionally impacting the adult population. This study describes the experiences after repurposing a PICU and its staff for adult critical care within a state mandated COVID-19 hospital and compares the outcomes to adult patients admitted to the institution's MICU during the same period. Design: A retrospective chart review was performed to analyze outcomes for the adults admitted to the PICU and MICU during the 27-day period the PICU was incorporated into the institution's adult critical care surge plan. Setting: Tertiary care state University hospital. Patients: Critically ill adult patients with proven or suspected COVID-19. Interventions: To select the most ideal adult patients for PICU admission a tiered approach that incorporated older patients with more comorbidities at each stage was implemented. Measurements and Main Results: There were 140 patients admitted to the MICU and 9 patients admitted to the PICU during this period. The mean age of the adult patients admitted to the PICU was lower (49.1 vs. 63.2 p = 0.017). There was no statistically significant difference in the number of comorbidities, intubation rates, days of ventilation, dialysis or LOS. Patients selected for PICU care did not have coronary artery disease, CHF, cerebrovascular disease or COPD. Mean admission Sequential Organ Failure Assessment (SOFA) score was lower in patients admitted to the PICU (4 vs. 6.4, p = 0.017) with similar rates of survival to discharge (66.7 vs. 44.4%, p = 0.64). Conclusion: Outcomes for the adult patients who received care in the PICU did not appear to be worse than those who were admitted to the MICU during this time. While limited by a small sample size, this single center cohort study revealed that careful assessment of critical illness considering age and type of co-morbidities may be a safe and effective approach in determining which critically ill adult patients with known or suspected COVID-19 are the most appropriate for PICU admission in general hospitals with primary management by its physicians and nurses.

Hemodynamic changes in cytokines, chemokines, acute phase proteins and prostaglandins in mares with subclinical endometritis.

Apparently healthy mares with conception failure or embryonic loss may have subclinical endometritis (SE). Our objective was to document evidence of systemic immune responses against SE in mares. In apparently healthy (control) mares as well as those with chronic endometritis (ChE) or subacute suppurative endometritis (SSE), both considered classes of SE, serum concentrations of cytokines (IL-1ß, IL-6, IL-10 and TNF-α), chemokines (IL-8), acute phase protein (SAA), and plasma concentrations of prostaglandins (PGF2α and PGE2) were measured using validated enzyme linked immunoassays (EIA). Mixed-breed mares of known reproductive history, were used. Based on an endometrial cytological examination, mares were allocated into the following groups: healthy (control), ChE, and SSE (12, 26 and 11 mares, respectively). Serum concentrations of IL-6, IL-8 and IL-10 and plasma PGF2α concentrations were increased (P < 0.01) in mares with SSE compared to healthy mares. Furthermore, serum concentrations of IL-6 (P < 0.05) and IL-10 (P < 0.05) were elevated in the ChE group compared to the healthy group whereas serum SAA (P < 0.01) and plasma PGE2 (P < 0.05) were higher in healthy mares compared to ChE and SSE mares. However, serum concentrations of IL-1ß and TNF-α were not significantly different among groups. In conclusion, there were two novel findings: (1) development of serum testing for a set of biochemical markers has promise to explore the pathogenesis of inflammation in mares with SE; and (2) none of the individual biomarkers studied, excluding IL-8, was a significant predictor of SE. However, serum IL-6:IL-10 and IL-6:TNF-α concentrations, as well as plasma PGE2:PGF2α ratios, may yield a novel diagnostic marker for chronic subclinical endometritis.

Role of Endoscopic Ultrasound-Guided Fine-Needle Aspiration of Portal Vein Thrombus in the Diagnosis and Staging of Hepatocellular Carcinoma.

BACKGROUND/AIMS: Malignant portal vein thrombus (PVT) is found in up to 44% of patients with hepatocellular carcinoma (HCC). The nature of the thrombus influences treatment selection. The aim of this study was to assess the safety and efficacy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in determining the nature of PVT in liver cirrhosis and/or HCC. METHODS: A prospective study was conducted in 34 patients with liver cirrhosis and/or HCC with PVT. Under EUS guidance, PVT was punctured using a 22 G FNA needle (Cook Medical, Bloomington, IN, USA) followed by monitoring of the puncture tract using color Doppler. Patients were followed for adverse events 2 hours after recovery. RESULTS: Throughout the 30-month study period, 34 patients, including 24 males with a mean age of 59±8 years, were enrolled. There were 8 patients with known HCC and 26 with no liver masses detected by computed tomography (CT). EUS-FNA from PVT was positive for malignancy in 3 patients (8.8%), of which only 1 patient was diagnosed with HCC by CT and 2 patients were newly diagnosed with HCC after EUS-FNA. No major complications were reported. CONCLUSION: EUS-FNA is a safe and effective technique for determining the nature of PVT that does not fulfill the malignant criteria via imaging studies in patients with liver cirrhosis and/or HCC.
